Description of specific embodiments

Detailed reference is made to specific embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Where possible, similar reference position will be used on the drawings to denote similar elements.

Referring to figure 1, a vacuum cleaner includes a housing 10, the suction nozzle 20, the sliding tube 30 connected to the suction nozzle 20, to change the length, the node 40 of the handle on one side of the sliding tube 30, and the connecting sleeve 50, connected between the node 40 of the handle and the housing 10.

Node handle 40 is provided for holding by the user.

The housing 10 and the node 40 pens contain the transmitting device 100 and receiving device 200 installed, respectively, on them to communicate with each other by ultrasonic waves.

If the transmitting device 100 is installed on the housing 10, then the receiving device is installed on the node 40 of the handle and Vice versa.

The housing 10 contains a control device (not shown)located therein, to control the radiation of the ultrasonic wave from the transmitting device 100 and receiving ultrasonic wave receiver 200.

Electrical cable 60 passes inside the connecting sleeve 50 and is connected between the interior of the housing 10 and Oslo the handle 40. Electrical cable 60 connects the control device (not shown) with the transmitting device 100 or the receiving device 200 installed on the node 40 of the handle.

The transmitting device 100 or the receiving device 200 on the housing 10 is also connected to the control device (not shown) to perform a working command of the control device.

The wheels 11 are installed on both sides of the inside of the housing 10 to move the chassis, and the wheel 11 is connected with a driving device (not shown)such as a motor in the housing, and a drive unit (not shown) connected to the control device (not shown) for driving wheels 11 running control device for moving body 100.

In this case, though, it is preferable that, if the receiving device 200 or the transmitting device 100 is installed on the housing 10, two wheels 11 were located on the front side of the housing 10, and one wheel 11 was located on the rear side of the housing, the location of the wheels is not limited to this.

The receiving device 200 or the transmitting device 100 located on the housing 10, thus, sets of ultrasonic communication with the transmitting device 100 or the receiving device 200 located on the node 40 of the handle.

If the transmitting device 100 to the node 40 of the handle transmits ultrasound is a new wave in the direction of the receiving device 200 (or if the transmitting device 100 on the housing 10 transmits an ultrasonic wave toward the receiving device 200 to the node 40 of the handle), the distance between the transmitter 100 and the receiver 200 is calculated on the basis of the achieved distance and period of time of the ultrasonic wave, and the distance used for the tripartite measurements to determine the position of the node 40 of the handle relative to the body.

In this case, the period of time an ultrasonic wave is calculated from the time of radiation of ultrasonic waves by the transmitting device 100 to the starting time of reception of the ultrasonic wave receiver 200.

The basic principles of the tripartite measurement will be described with reference to figa.

The tripartite dimension is the method of obtaining the relative position of the object through the use of a triangular shape. To obtain the position of the object by way of a tripartite measurement uses two or more than two reference points and the distances to the reference points of the object.

Only for accurate and defining the relative position in two dimensions through a tripartite measurement requires at least three control points.

If you want to get the relative position of the point T from the reference points P1, P2 and P3, SN is Chala get the distance r1 from P1 to T, the distance r2 from P2 to T and the distance r3 from P3 to T.

Then the point T becomes the point of intersection of the sphere S1 of radius r1 of the sphere S2 of radius r2 and the sphere S3 with radius r3. Then, we determine the coordinates of the position of point T on the X-axis, Y-axis and Z-axis, as indicated below.

Equation 1

r12=x2+y2+z2

r22=(x-d)2+y2+z2

r32=(x-i)2+(y-j)2+z2

x=

y=

z=

Where x, y and z coordinates, respectively, on the X-axis, Y-axis and Z-axis, d is the distance between P1 and P2 on the X-axis, i is the distance between P1 and P3 on the X-axis, and J is the distance between P1 and P3 on the axis Y. In this example, the Z-axis has only a positive value.

FIGU is a schematic view depicting the perceived position of the node 40 of the handle through the use of data on the distance obtained on the basis of ultrasonic communication between the transmitting device 100 to the node 40 of the handle and the receiver 200 on the body, the tripartite dimension in a vacuum cleaner of the present invention.

Although the tripartite dimension described with reference to a case in which the transmitting device 100 installed on the node 40 of the handle, and the receiving device 200 is installed on the housing 10 on FIGU, the installation position can be varied places the mi.

In this case, the provisions of the receiving devices 200 on the housing 10 are reference points P1, P2 and P3, the position of the transmitting device 100 to the node 40 of the handle is the point T.

By calculating and perception of distances (speed achievements/periods of time) between P1, P2 and P3, and through the use of triangular measurement can be obtained the exact position of the point T.

When receiving the position of point T through the use of triangular measurement is the process in which the position of the point T is converted to a position in the coordinate system of the body 10, in which the front end of the body taken as a reference starting position F.

In this case, since all points of the reference source position F P1~P3 and the position of the point T is known, it is easy to convert the position of the point T obtained through tripartite dimension, the position in the coordinate system of the body 10.

In line with this is fixed relative position and distance of the point T, i.e. the node 40 of the handle, relative to the reference source position F in the coordinate system of the body 10.

In this case, the most important are the relative position of the node 40 of the handle on the X-axis and Y-axis of the coordinate system of the body, as they are important parameters for the calculation of the direction of rotation, the degree of rotation and the distance between the node handle 40 and the housing 10.

That is, by determining the change of position of point T in the coordinate system of the body 10 and a previous position of point T this point T is possible to know the change of position of the node 40 of the handle and the distance between the node 40 of the handle and the housing 10.

Figure 3 - block diagram of the device 300 used in a vacuum cleaner of the present invention, in which the device 300 has the difference E (Ex, Ey, Ez) as input, which is the difference between the positions (Xs, Ys, Zs) of a reference point, i.e. the relative position of the housing relative to the node handle, which assumes the presence of the hull, and the actual relative positions (X, Y, Z), and the linear velocity V, the angular velocity W (or the speed of the two wheels), with which the body should move, as output.

4 is a block diagram of the control according to the first preferred embodiment of the present invention.

The first version of the implementation includes one transmitting device 100 installed on the node 40 of the handle, and three receiving device 200 mounted on the housing. The transmitting device 100 and receiving device 200 is connected to the device 300 of the control.

The receiving device 200 is connected to the device 300 control cables passing through the inner part to the pus 10, and the transmitting device 100 is connected to the device 300 control via cable 60 passing through the interior of the connecting sleeve.

In accordance with the command device 300 controls the transmitting device 100 emits an ultrasonic wave toward the reception device 200, and the ultrasonic wave radiated thus, taken a receiving device 200.

Preferably, the receiving device 200 provided communication with the transmitting device 100 under the control device 300 controls simultaneously or alternately.

As the speed of ultrasonic waves is about 340 m/s by multiplying the speed for periods of time for which the ultrasonic wave passes, respectively, of the transmitting device 100 and receiving device 200, can be obtained distances, respectively, between the transmitting device 100 and receiving device 200.

Through the use of distances between the transmitting device 100 and receiving device 200 and the data on the distance between the receiving device 200 in a triangular measurement, calculates the position of the transmitting device, and by using the position of the transmitting device 100 in the coordinate system of the body can be calculated by the relative position of the transmitting device 100 Rel the relative reference point (the front point of the body) coordinate system of the body.

Since the transmitting device 100 installed on the node 40 of the handle, the distance between the node 40 of the handle and the housing 10 can be obtained through the above-mentioned method.

The device 300 control is connected with a driving device 400, and the driving device 400 is similar to the drive motor connected to the wheels 11 (see figure 1) to move the housing 10.

Therefore, if the distance between the node 40 of the handle and the housing 10 is not appropriate, the device 300 controls the driving device 400 for rotation of the wheels 11 to force the body 10 to move closer to the node 40 of the handle or may be located at a greater distance from the node 40 of the handle.

If the position of the node handle 40 is moved in the directions left/right or rotated, the device 300 management determines the change of the position transmitting device 100 and controls the driving device 400 and the wheels 11, respectively, to cause the housing 10 to rotate or to move in the directions left/right in accordance with the trajectory of the node 40 of the handle.

5 is a block diagram of a control in accordance with the second preferred embodiment of the present invention.

The second variant of implementation differs from the first variant of realization of the fact that the receiving device 200 in which tableno on node 40 of the handle, and many of the transmitting device 100 is installed on the housing 10, while other parts are identical to the first variant implementation.

In this example, when there are three transmitting device 100, assuming that three of the transmitting device 100 is referred to as a first transmitting device 101, the second transmitting device 102 and the third transmitting device 103, by using data on the distance between the first-third transmitting devices 101~103 and the receiving device 200 and the data on the distance between the transmitting devices in a triangular measurement can be determined the position of the receiving device 200 to the node 40 of the handle and then through the use position of the receiving device 200 in the coordinate system of the body can be calculated relative position and the distance of the receiving device 200 relative to the reference source position coordinate system enclosure 10.

As a result, can be determined the distance between the node 40 of the handle and the housing 10 and the relative position, and based on this, like the first variant implementation through actuation of the driving devices 400 and wheel 11 (see Fig 1) under the management device 300, the control can be performed adjusting the distance between the housing 10 and the node 40 of the handle and rotate the housing 10.

T is is, in comparison with the first embodiment except that only changed the position and number of the transmitting device 100 and the node 40 of the handle, the control movement of the body 10 with respect to the relative position, distance and direction of rotation between the hub 40 of the handle and transmitting devices 100 are identical.

This is similar to the second variant implementation, if the number of transmitting devices 100 more receiving devices 200, and if the transmitting device 100 to emit ultrasonic waves toward the receiving device 200 at the same time, noise may occur when receiving signals.

Therefore, it is necessary that the connection between the transmitting device 100 and receiving device 200 installed in sequence.

In detail, if the first transmitting device 101 transmits an ultrasonic wave receiving device 200 receives the ultrasonic wave, and the device 300, the control calculates the distance between the first transmitter 101 and the receiver 200.

Then, if the second transmitting device 102 transmits the ultrasonic wave, the receiving device 200 receives the ultrasonic wave, and the device 300, the control calculates the distance between the second transmitter 102 and the receiver device 200.

Then, if the third transmitting device 103 before the t of the ultrasonic wave, the receiving device 200 receives the ultrasonic wave, and the device 300, the control calculates the distance between the third transmitter 103 and the receiver 200.

Then, by using the data about distances between the first~third transmitting devices 101~103, which is already known, and the data about distances between the transmitting device 100: 101~103 and the receiving device 200 in a triangular measurement can be determined the position of the node 40 of the handle, which is the receiving device 200.

6 is a perspective view of the vacuum cleaner, container type in accordance with a third preferred embodiment of the present invention.

The cleaner of the third preferred variant implementation differs from the vacuum cleaner of the first preferred variant implementation that although the vacuum cleaner of the first variant implementation contains one transmitting device 100 installed on the node 40 of the handle, the vacuum cleaner of the third variant of the implementation contains two transmitting device 100 installed on the node 40 of the handle. Except for the aforementioned cleaners first and third embodiments are identical.

The node 40 of the handle includes a latch 550 mounted thereon, and transmitting devices 100 are installed on both sides of the retainer 550 at a distance from each other. Two is erediauwa device 100 sets of ultrasonic communication, accordingly, with many receiving devices 200 on the housing 10.

The latch 550 includes a first latch 551, which is a projecting part from the node 40 of the handle, and a second latch 552, which is a projecting part from the end of the first latch 551 on both sides for mounting, respectively, the transmitting device 100.

In accordance with these provisions of the transmitting device 100 is calculated by the tripartite dimension, and the relative position and the distance to the enclosure 10 may also be calculated.

In this state, if the user rotates the node 40 of the handle, the rotation direction and degree of rotation of the node handle 40 can be determined based on changes in position of each of the transmitting devices 100.

The reason is that since the latch 550 attached to the node 40 of the handle, making the trajectory of the node 40 of the handle and the trajectory of the retainer 550 is identical to, respectively, the trajectory of each of the transmitting devices 100 also corresponds to the trajectory of the node 40 of the handle.

Based on this, the device 300 (see Fig.7) determines the direction and degree of rotation of the housing 10 and accordingly moves the housing 10.

However, the provisions of the transmitting device 100 and receiving device 200 are interchangeable.

7 is a block diagram administered the I in accordance with the third preferred embodiment of the present invention.

As described above, the node 40 of the handle contains the first transmitting device 110 and the second transmitting device 120 installed on it, and the casing 10 contains a number of receiving devices 200 located on it. If there are three receiving device 200, the first receiving unit 201, the second receiving device 202 and the third receiving device 203.

The first and second transmitting devices 110 and 120 and the device 300 controls are connected by electric cables 60, passing inside of the connecting sleeve, and the first through third receiving devices 201-203 and the device 300 controls are connected by electric cables in the housing 10.

In this case, to prevent from interference with each other, a first set of ultrasonic communication between the first transmission unit 110 and the first to third receiving device 201~203, and the calculated distance between the first transmission unit 110 and the first to third receiving devices 200.

Then, set ultrasonic communication between the second transmission unit 120 and the first to third receiving device 201~203, and calculates a distance between the second transmission unit 120 and the first to third receiving devices 200.

The device 300 management ensures implementation of this phase uses the information about the distance of three is tarannum measurement to determine the positions of the first transmitting device 110 and the second transmitting device 120, specifies the displacement of the node handle 40 on the basis of changes of the provisions of the first and second transmitting devices 110 and 120 and controls the movement of the body 10 in accordance with certain so moving.

However, changes in the terms and amounts of the transmitting device 100 and receiving device 200 is also included in the scope of the present invention.

Fig - block-control circuit in accordance with a fourth preferred embodiment of the present invention.

The cleaner of the fourth preferred option implementation differs from the vacuum cleaner of the first preferred variant implementation, the fact that the cleaner of the fourth version of the implementation contains the sensor 600 movement that is installed on the node 40 of the handle for precise determination of the rotation of the node 40 of the handle.

Sensor 600 motion sensor is used in cellular phone and the like to determine changes in position caused by the movement of the object (cell phone).

As the sensor 600 movement is connected to the device 300 control using electric cable 60 passing through the connecting sleeve, the rotation direction and degree of rotation of the node 40 of the handle defined by the sensor 600 movements are transmitted to the device 300 management and are used as the basic data for management of the housing 10.

When this is the fourth version of the implementation also includes the node 40 of the handle with the transmitting device 100, installed on it, and the housing 10 with the first to third receiving devices 200: 201~203 installed on it. Description ultrasonic communication between the above-mentioned transmitting device 100 and receiving device 200, the distance calculation and the calculation of provisions that have already been completed, will be omitted.

Figa and 9b is schematic views showing changes in the position of the body 10 in accordance with the rotation of the node 40 of the handle in the third or fourth embodiment, respectively.

Definition of rotation of the node 40 of the handle, on the basis of changes in the two transmitting devices 100 mounted on the latch 500 (see Fig.6), can be performed in the third embodiment, or the determination of the rotation of the node handle 40 on the basis of the sensor 600 movement (see Fig.7), installed on the node 40 of the handle, can be performed in the fourth embodiment.

Usually, if the node 40 of the handle makes a great twist in most cases the user is facing the direction of rotation of the node 40 of the handle.

That is, like the condition on the left side on figa or condition on the left side on fig.9b if the node handle 40 is moved at a given range the anterior region of the housing 10, the housing 10 is converted in the forward direction, and in this case, the user will be facing in the forward direction.

Just like the condition on the right is the thoron on figa, if the user turns in the left direction for change, respectively, the position of the node 40 of the handle, the body 10 will move in this direction.

Therefore, similar to the condition on the right side on fig.9b device 300 controls the body 10 to move, taking into account the direction of rotation and the degree of rotation of the node 40 of the handle and the relative distance to the node handle.

Figure 10 - block diagram of the control in accordance with the fifth preferred embodiment of the present invention.

In this case a vacuum cleaner fifth variant of the implementation differs from the vacuum cleaner of the first variant of realization of the fact that the cleaner fifth variant of the implementation contains additional transmitting device 150 installed on the housing 10.

Additional transmitting device 150 is connected to the device 300 controls for radiation of ultrasonic waves on the outer side of the housing 10 under the control device 300 controls.

Additional transmitting device 150 is used to emit ultrasonic waves to determine the position of the body 10 and measure the distance from the housing 10 to the obstacle near the housing 10.

Therefore, additional ultrasonic wave transmitting device 150 is picked by the receiving device 200 located on the housing 0, after reflection of ultrasonic waves from obstacles near the housing 10.

This is similar to the mechanism in which the bat is studying ultrasonic wave and receives the reflected ultrasonic wave for the perception of obstacles near the bat, and determines the distance to the obstacle.

Therefore, if the receiving device 200 receives the ultrasonic wave reflected thus, the device 300 management determines the presence and position of obstacles near the housing 10, and measures the distance between the obstacle and the housing 10.

Thus, if the device 300 management determines the obstacle, measures the distance between the obstacle and the housing 10, and determines that the distance between the obstacle and the housing 10 is within a predefined distance, the device 300, the control actuates the drive unit 400 and the wheel 11 (see figure 1) for the location of housing 10 at a specified distance from an obstacle.

Thus, it is possible to prevent the housing 10 from bringing into contact and impact with an obstacle.

It is necessary to prevent interference between the connections of the transmitting device 100 with the receiving device 200 and the additional transmitting device 150 with receiving devices 200.

Therefore, first, the transmitting device 100 emits an ultrasonic wave, priem the e device 200 receives the ultrasonic wave, and the device 300 control determines the distance between the transmitter 100 and the receiver 200, and uses the distance in a triangular measurement to calculate the position of the node 40 of the handle containing the transmitting device 100 located on it.

After completion of the transmission ultrasonic wave transmitting device 100 additional transmitting device 150 emits an ultrasonic wave near the housing 10, and a part of the ultrasonic waves emitted thereby is picked by the receiving device 200 after the reflection of ultrasonic waves from obstacles near the housing 10.

As a result, by determining the position and distance of the housing 10 by means of the ultrasonic wave reflected thus, the device 300 control adjusts the position of the body 10.

The above steps are repeated to calculate the position of the node 40 of the handle and position of the obstruction.

As shown in figure 11, if the user holds the node 40 of the handle and cleans the connection between the transmitting device 100 (or the receiving device 200)that is installed on the node 40 of the handle, and the receiving device 200 (or the transmitting device 100)mounted on the body 10.

In accordance with this measured distance between the transmitting device 100 and receiving device 200, based on the distance R is Scituate the distance between the node 40 of the handle and the housing 10 and the position of the node 40 of the handle through a tripartite dimension.

Therefore, if the distance between the housing 10 and the node 40 of the handle is higher than the given reference distance D at the moment, the housing 10 is moved to the node 40 of the handle for setting the distance between the housing 10 and the node 40 of the handle is equal to the reference distance.

If the distance between the housing 10 and the node 40 of the handle is less than the specified reference distance D, the housing 10 is moved in the direction opposite to the node 40 of the handle, for setting the distance between the housing 10 and the node 40 of the handle is equal to the reference distance.

Fig. 12 and 13, the precedence diagram showing the steps of a method of controlling a vacuum cleaner in accordance with a preferred embodiment of the present invention.

First, the transmitting device emits an ultrasonic wave (S1201). Then, the receiving device receives the ultrasonic wave from the transmitting device (S1202).

After receiving the ultrasonic wave of the ultrasonic wave is multiplied by the obtained time period.

In accordance with this measured distance between receiver and transmitter, measured in this way the distance is used when the tripartite dimension for calculating the position of the transmitting device or the receiving device on the handle to obtain the position of the node handle (S1203).

Through the use of p is the position of the node handle, thus obtained in the coordinate system of the body, the relative position of node handles on the basis of the reference source position coordinate system of the body, and the distance between the node of the handle and the housing can be installed.

When the distance of the node to handle the case set is thus determined exceeds or not the distance between the node of the handle and the housing preset reference distance (S1204).

In the result of the determination, if the distance exceeds the reference range, indicating that the distance between the node of the handle and the housing is too large, to reduce the distance the control unit moves the body in the direction of node handles (S1205).

Meanwhile, if the distance does not exceed, but does not reach the predetermined reference range, indicating that the case is too close to the node of the handle so that the user can engage with the housing, the control unit moves the body in a direction opposite to the node handle (S1206).

Meanwhile, if the distance between the node of the handle and the housing is within a predetermined reference range, this condition is maintained (S1207).

After moving the hull again determines is or not the distance between the node of the handle and the housing within a predetermined reference range (S1208), and if so, the case ostanavlivaetsa the (S1209).

The rotation of the node handle can be known by determining motion sensor, or by comparing the provisions of the transmitting device or the receiving device on the node handles before and after the rotation.

Therefore, determines is rotated or not the node handle (S1301), if rotated, the control unit determines the rotation direction and degree of rotation of the node handle (S1302), and moves the housing in accordance with the direction and degree of rotation of the node handle (S1303).

Meanwhile, as described above, is determined, or is no obstacle within a predetermined distance from the housing by ultrasonic connection between the secondary transmitter and the receiver (S1304).

Accordingly, if it is determined that the obstacle is within a specified distance from the housing, the control unit moves the housing at a distance from the obstacle, the greater the distance you set.

If the obstacle is located at a greater distance from the body than the specified distance, the control unit stops the body (S1305).

Even if Fig. 12 and 13 illustrate that the movement of the body following the movement back and forth of the node handle, moving the enclosure, following the rotation of the node handle, and movement of the body caused by the obstacle is performed using one with the person, the movement of the body in each scenario can be run independently.

As described, a vacuum cleaner and a method of controlling a vacuum cleaner of the present invention have the following advantages.

As the body moves automatically, following the move node handle, if the user moves a node handle, the user does not need to pull a case with the effort.

As the body moves automatically, if the user moves backward, the user will not have trouble with the link with the case.

In addition, since the vacuum cleaner makes it easy to determine the position of the obstacle, and determines the distance from the hull to the obstacles and avoids an obstacle, the body damage caused by hitting an obstacle, can be prevented.

In addition, since the vacuum determines the direction of rotation of the node handle and rotates the casing, even if the user rotates the casing, user convenience is increased.
