Described herein embodiments of, in General, are related to the electric vacuum cleaner with the function of the phase control of the electric fan.

Usually the electric vacuum cleaner of this type includes a main body of a vacuum cleaner, which contains an electric fan. In the main body of the vacuum cleaner dust Luggage (dust precipitation chamber) is formed communicating with the intake side of the electric fan. Dust Luggage has an element for collecting dust, such as dust bag or container to collect dust, and keeps the dust which is sucked by driving the electric blower of a vacuum cleaner.

In such an electric vacuum cleaner, it is desirable that the suction power of the electric fan was variable depending, for example, the amount of dust on the surface being cleaned. If the suction power is variable, the input current of the electric fan, in General, can have an adjustable phase.

This technical problem was solved due to the fact that the electric vacuum cleaner according to the invention contains an electric fan; a control to set the phase angle of the input current of the electric fan; a variable resistor that sets with the ability to change the resistance value and through which the your this setting with the possibility of changing the capacity of the electric fan; and management tool for establishing, in accordance with the resistance value of the variable resistor of the phase angle of the input current of the electric fan, specified through the control range of a predefined phase angle, harmonics which are generated with a value not less than the specified limit values.

Preferably, the electric vacuum cleaner further comprises a means of measuring current to measure the current value of the electric fan, when the value of the current electric fan, measured by means of current measurement is not less than a preset value, the control sets the phase angle of the input current of the electric fan, specified through the control range of a predefined phase angle, harmonics which are generated with a value which is not less than the prescribed limit values.

Preferably, when the phase angle of the input current of the electric fan, specified through the control, less than or greater than a predefined phase angle, harmonics which are generated with a value which is not less than the prescribed limit value, the control changes the magnitude of the change is of a phase angle of the input current of the electric fan, asked by control, in accordance with the magnitude of the change of the resistance value of the variable resistor.

Preferably, the tool control sets the amount of change of the phase angle of the input current of the electric fan, specified through the control, in accordance with the magnitude of the change of the resistance value of the variable resistor, in the region in which the phase angle of the input current of the electric fan is less than a predetermined phase angle, harmonics which are generated with a value which is not less than a predefined limit value, and relatively increases the rate of change of the phase angle of the input current of the electric fan, which will be specified by the control corresponding to the rate of change of the resistance value of the variable resistor, in a relatively small area in which the phase angle of the input current electric fan more than a predefined phase angle, harmonics which are generated with a value which is not less than the prescribed limit values.

In figure 2 the reference position 11 marked the so-called electric vacuum cleaner, container type, and electric vacuum cleaner 11 has a main body 12 of the vacuum cleaner and element 13 forming an air duct, which is a tube and has the ability to detach from the main body 12 of the vacuum cleaner.

The main body 12 of the vacuum cleaner can be rotated and moved on the surface, and contains an electric fan 15 and the dust-collecting portion (not shown)which is communicated with the intake side of the electric fan 15. The suction hole 17 of the main body, which communicates with the dust collection part, and to which is attached the end of the element 13 forming a duct from the base, open on the front side of the main body 12 of the vacuum cleaner. The switch 18 power supply that is used to turn on/off the electrical part, which includes an electric fan 15, that is used to turn on/off the electric vacuum cleaner 11, is located on the upper part of the main body 12 of the vacuum cleaner in that the second position, which is addressed to the user and can be visually recognized by the user. The adjusting portion 19, which serves to enable the user tasks with the possibility to change the suction power of the electric fan 15, is located approximately in the Central part of the upper part of the main body 12 of the vacuum cleaner. The outlet 20 is formed on the main body 12 of the vacuum cleaner for release.

Element 13 forming duct includes: a connecting tube 21 connected to the suction inlet 17 of the main body; a flexible hose 22 connected to the extremity of the connecting tube 21; part 23 manual control provided at the tip of the hose 22, which allows the user to hold element 13 forming an air duct and to control them; telescopic tube 24 connected to the end part 23 of manual control with the possibility of disconnection; and sexual brush 26 as part of the suction holes connected to the extremity of the telescopic tube 24. Element 13 forming duct is an integral part of the duct where the duct connected to the suction side of the electric fan 15, together with the dust collection part, etc. is divided into several parts.

For example, the dust-collecting portion may avlat the Xia dust bag, such as, for example, paper bag, paleological device, such as, for example, cyclone (centrifugal) the separation device, or simply filter the filter and keeps the dust which is sucked together with air through the element 13 forming the duct by driving the electric fan 15 of the vacuum cleaner.

Next will be described the internal structure of the electric vacuum cleaner 11.

As shown in Figure 5, the sequential connection of the electric fan 15 and the element 31 control electric vacuum cleaner 11 is electrically connected to an electrical outlet e AC, for example, voltage range 100-240V via a power cord (not illustrated). The cord is wound on a coil of cord in the main body 12 of the vacuum cleaner (figure 2)and plug the end part of the cord connected to a power outlet on a wall surface or the like, is located outside of the main body 12 of the vacuum cleaner (Figure 2). The plug part of the power cord is pulled out of the coil cord to connect to a power outlet located far from the main body 12 of the vacuum cleaner (Figure 2), and wound on the coil cord to the main part of the cord was placed in the main body 12 of the vacuum cleaner (Figure 2).

Item 31 control the population controls the phase of the mains e AC to set the phase angle of the input current of the electric fan 15. For example, the element 31 of the control may be a control alternating current, such as symmetric triode thyristor, and managing contact 31a is electrically connected to the means 32 of the control.

The tool 32, the control turns on/off the element 31 by transmitting a trigger signal to the control contact element 31a 31 management, and determines the phase angle of the input current of the electric fan 15, which will be specified by the element 31 of the control. The tool 32 control electrically connected to the variable resistor 33. For example, the tool 32 control may be a digital circuit of a microcomputer or the like, and can detect the point of zero crossing of the waveform of the mains voltages e AC tool 34 detection of zero crossing, such as the well-known scheme of detection of zero crossing.

In this case, the adjusting element 33a of the variable resistor 33 is connected with the adjusting part 19 (Figure 2) and is moved by sliding the adjusting part 19 (2), and thus the resistance value can be set with the possibility of change. The characteristic of the change of the resistance value of the variable resistor 33 is smooth, no point bending, at least in the area is relevant to a predefined range of phase angle, approximately 90aboutharmonics which are generated with a value which is not less than the prescribed limit value L (for example, limit values established by the IEC, Figure 4). In the embodiment, in particular, as shown in figure 3(a), the resistance value of the variable resistor 33 increases, for example, by moving the adjusting part 19 (Figure 2) to one side (e.g. left side) and decreases as you move regulation section 19 (2) in the other direction (for example, right side). That is, the resistance value of the variable resistor 33 is changed in a linear manner. In addition, one end of the variable resistor 33 is electrically connected with a pre-defined source of DC voltage (not shown), the other end is grounded, the voltage of the DC power voltage is divided by a change of the resistance value, and the divided voltage is read using the 32 control.

That is, the means 32 performs control to digital conversion and reading the divided voltage corresponding to the resistance value, which is an analog value of the variable resistor 33 in each cycle zero-crossing detected using means 34 discovery go to the Yes through zero, and thus determines the timing trigger signal (trigger pulse), which must be transferred to the element 31 of the control, in addition, determines the phase angle of the input current of the electric fan 15, which will be specified by the element 31 of the control. In other words, the tool 32 management delivers the trigger signal corresponding to the off time of the point of zero crossing, the control contact element 31a 31 control for on/off element 31 of the control, and also controls the input current of the electric fan 15. Accordingly, the electric vacuum cleaner 11 sets the capacity of the electric fan 15 with the possibility of change through a variable setting the value of resistance of the variable resistor 33.

For example, when determining the phase angle of the tool 32, the control compares the read divided voltage with a table of ratios stored in the storage medium (not illustrated). For example, as shown in figure 3(b), the table of ratios of input current linearly increases (decreases) with decreasing (increasing) the resistance values in the field And in which the resistance value of the variable resistor 33 is less than a predefined first threshold, which was set in advance, a constant input current is independent is IMO from changes (increase/decrease) the magnitude of the resistance of the variable resistor 33 in the region, in which the value of resistance of the variable resistor 33 is not less than a predefined first threshold and less than a predefined second threshold that has been set in advance in the phase angle approximately equal to 90, the harmonics which are generated with a value which is not less than the prescribed limit value L (Figure 4), and input current linearly increases (decreases) with decreasing (increasing) the resistance values in the area C in which the value of resistance of the variable resistor 33 is not less than a predefined second threshold, which was set in advance. That is, in the table of ratios of the phase angle specified through the element 31 of the control, set the range of the phase angle approximately equal to 90, the harmonics which are generated with a value which is not less than the prescribed limit value L (Figure 4). Moreover, for example, the rate of change of the input current, i.e. the magnitude of change of the input current corresponding to the magnitude of the changes resistances in area A and area C, are approximately equal to each other.

Moreover, in the embodiment, since the tool 32 control is a digital circuit, the input current table of correlations is clearly a stepped shape. However, since re is hell between steps can be arbitrarily set low in the range, no problems in practical use, a description will be given with the assumption that the input current table of correlations is smooth.

Next will be described the actions when working with the first embodiment of the invention.

The user electrically connects the electric vacuum cleaner 11 to the outlet e of AC power by connecting the power cord from the outlet, runs the electric vacuum cleaner 11 by switching switch 18 power, moves the adjusting portion l9 to the left or right depending on the situation with regard to the type, amount of dust or the like to the surface and stops the adjusting portion 19 in the position in which the suction power of the electric fan 15 corresponds to a desirable suction power.

That is, the means 32 performs control to digital conversion and reading the divided voltage in each cycle of zero crossing detected using means 34 detection of zero crossing, and the divided voltage corresponding to the resistance value of the variable resistor 33 is set based on the position displacement of the adjusting element 33a of the variable resistor 33, corresponding to the position displacement adjustment part 19 set p is loveteam, but the means 32 of the control depending on the divided voltage sets the time of the transfer trigger signal to the element 31 of the control and thus sets the phase angle of the input current of the electric fan 15 specified through the element 31 of the control.

In particular, as shown in figure 3(b), when the resistance value of the variable resistor 33 is in region A, the tool 32 management linearly increases (decreases) the input current is decreasing (increasing) the resistance values.

When the resistance value of the variable resistor 33 is in region B, the tool 32, the controller sets a constant input current regardless of changes (increase/decrease) the magnitude of the resistance of the variable resistor 33.

In addition, when the resistance value of the variable resistor 33 is in region C, the tool 32 management linearly increases (decreases) the input current is decreasing (increasing) the resistance values.

As a result, as shown in Figure 4, the magnitude of the current (third) harmonic does not exceed a given limit value L.

The user makes an electric vacuum cleaner to suck the dust from the air by the negative pressure generated by driving the electric fan 15, preferably running on the power, with the surface being cleaned through the element 13 forming duct, including sexual brush 26, etc. Sucked dust is transferred from the air and collected on the dust part. Moreover, the air remaining after separation of the dust, comes to electric fan 15, and then is released outside of the main body 12 of the vacuum cleaner through the outlet 20.

After harvest, the user switches the switch 18 power supply to turn off the electric vacuum cleaner 11 (electric fan 15).

As described above, in accordance with the first embodiment, the tool 32 control sets depending on the magnitude of the resistance of the variable resistor 33 phase angle of the input current of the electric fan 15 specified through the element 31 of the control range of a predefined phase angle approximately equal to 90, the harmonics which are generated with a value which is not less than the prescribed limit value L, so the harmonics contained in the input current, can be suppressed when using the universal variable resistor 33.

Next, with reference to Figure 5-7 will be described second variant implementation. In addition, since the same reference position belong to the same configurations and actions with p the pout of the embodiment, their description will be omitted.

In the second embodiment, as shown in Figure 5, the means 32 controls the first variant implementation using the 37 current measurement measures the amount of current supplied to the electric fan 15.

Only when the value of current measured by using the 37 current measurement, electric fan 15 is not less than a preset value which has been set in advance, the tool 32 control sets the phase angle of the input current of the electric fan 15 specified through the element 31 of the control range of a predefined phase angle approximately equal to 90, the harmonics which are generated with a value which is not less than the prescribed limit value L.

In particular, as shown in Fig.6, the tool 32 control depending on the current value measured by using the 37 current measurement, electric fan 15 selects the desired table relationships from a variety of tables, relationships, stored in the storage medium, or sets with the possibility of changing the first and/or second threshold table of the ratios and therefore can change the range of the region corresponding to a predefined range of phase angle approximately equal to 90, the harmonics of which g is generated from the current value, the value of which is not less than the prescribed limit value L. In particular, the tool 32 control reduces the scope In, when the current value measured by using the 37 current measurement, electric fan 15 is relatively small (less than a pre-specified value), and increases the scope, when the current value measured by using the 37 current measurement, electric fan 15 is relatively large (at least a pre-specified value). In addition, the range of the field can be changed on multiple stages or without stage. Moreover, the region should not exist when the job is minimum.

When the amount of air sucked in by the vacuum cleaner in an electric fan 15, the relatively reduced, for example, in dust-parts etc. received at least a predefined amount of dust, the amount of current of the electric fan 15 is relatively reduced. Therefore, as shown in Fig.7 additional dash-dotted line, the current (third harmonic) is also reduced. Accordingly, when the current value measured by using the 37 current measurement, electric fan 15 is relatively reduced (does not exceed a preset value), the current (third) harmonic does not exceed a predetermined limit value L, the even if the tool 32 control reduces the scope Century

As described above, in accordance with the second embodiment, the means 32 of the control when the value of the current detected by the means 37 of the detection current, the electric fan 15 is not less than a predefined value which has been set in advance, determines the phase angle of the input current of the electric fan 15, which will be specified by the element 31 of the control range of a predetermined phase angle approximately equal to 90, the harmonics which are generated with a value which is not less than a predetermined value L, and thus, for example, when the value of electric current the fan 15 is less than a predefined value, and almost no harmonics are generated, the power management means 32 of the control can be simplified, and the change in power of the electric fan 15 may be smoother, corresponding to the operation stroke of the adjusting portion 19, that is, the change in the value of the resistance of the variable resistor 33.

In addition, in each of the above embodiments, the input current set using the 32 management in the area do not always have to be constant up until a specified value of the harmonics will not exceed zadanu the limit value L.

Next, with reference to Fig will be described a third option implementation. In addition, since the same reference position belong to the same configurations and operations for each of the above embodiments, their description will be omitted.

In the third embodiment, as in each of the above embodiments, in the case where the phase angle of the input current of the electric fan 15 specified through the element 31 management, less than or greater than a predefined phase angle of 90, the harmonics which are generated with a value which is not less than the prescribed limit value L, the means 32 of the control changes the value of the change in phase angle of the input current of the electric fan 15 specified through the element 31 of the control, in accordance with the magnitude of the change of the resistance value of the variable resistor 33.

In particular, the tool 32 control sets the amount of change of the phase angle of the input current of the electric fan 15 specified through the element 31 of the control corresponding to the change in resistance value of the variable resistor 33, relatively small in area D, in which the phase angle of the input current of the electric fan 15 is less than the phase angle of 90 in this embodiment, the harmonics of the which are generated with the value the value of which is not less than the prescribed limit value L, and sets the amount of change of the phase angle of the input current of the electric fan 15 specified through the element 31 of the control corresponding to the change in resistance value of the variable resistor 33 is relatively large in area E in which the phase angle of the input current of the electric fan 15 is not less than the phase angle of 90 in this embodiment, the harmonics which are generated with a value which is not less than the prescribed limit value L. that is, since the rate of change of phase angle is set by means of the table relationships in the field of E greater than in region D, the tool 32 management sets the phase angle specified through the element 31 of the control of the phase angle (approximately 90), the harmonics which are generated with a value which is not less than the prescribed limit value L.

Accordingly, the input current linearly increases (decreases) with decreasing (increasing) the resistance value when the resistance value of the variable resistor 33 is located in the region D, in addition, the input current linearly increases (decreases) when the degree of change is greater than in region D, decreasing (increasing) the resistance values when the size of the resistance of the variable resistor 33 is in the area E.

As described above, in accordance with the third embodiment when the phase angle of the input current of the electric fan 15 specified through the element 31 management, less than or greater than a predefined phase angle, harmonics which are generated with a value which is not less than the prescribed limit value L, the means 32 of the control changes the value of the change in phase angle of the input current of the electric fan 15 specified through the element 31 of the control, in accordance with the magnitude of the change of the resistance value of the variable resistor 33 and thus can more smoothly change the capacity of the electric fan 15 in accordance with control of the adjusting part 19 the user, that is, the changing rate of the resistance of the variable resistor 33.

Basically, the user needs a precise regulation of the power of the electric fan 15 when setting a relatively low power and does not require precise regulation of the power of the electric fan 15 when setting a relatively high power. Then the change in phase angle of the input current of the electric fan 15 specified through the element 31 of the control corresponding to the change in resistance value of the variable resistor 33, octanal is by relatively small in area D, in which the phase angle of the input current of the electric fan 15 is less than the phase angle (90), the harmonics which are generated with a value which is not less than the prescribed limit value L, and the change in phase angle of the input current of the electric fan 15 specified through the element 31 of the control corresponding to the change in resistance value of the variable resistor 33, is set relatively large in area E in which the phase angle of the input current of the electric fan 15 more (not less) phase angle (90), the harmonics which are generated with a value which is not less than the prescribed limit value L. Therefore, when the capacity of the electric fan 15 is relatively small, the change in the input current (power) electric fan 15 is small even in the case when the user specifies a large stroke adjusting portion 19, and thus can be made precise power control. When the capacity of the electric fan 15 is relatively high, the user can widely change the input current (power) electric fan 15 with no job large stroke adjusting portion 19.

In accordance with at least one of the above embodiments, the tool 32 councils is to be placed, in accordance with the resistance value of the variable resistor 33, sets the phase angle of the input current of the electric fan 15 specified through the element 31 of the control range of a predetermined phase angle, that is, approximately equal to 90, the harmonics which are generated with a value which is not less than the prescribed limit value L, and thus the harmonics contained in the input current, can be suppressed when using the universal variable resistor 33. So no need to use expensive specialized variable resistor even, for example, for an electric vacuum cleaner 11, with different supply voltage and maximum input current, and can be provided an inexpensive multifunction electric vacuum cleaner 11, and can be eliminated reducing the power factor and the generation of noise caused by harmonics.

Since the electric vacuum cleaner 11 uses an electric fan 15, mainly uses a lot of current approximately equal to 10A controls the output electric fan 15 in a wide range from 0 to the maximum and is fixed in use on a particular input current, set by the user, it is easy to generate harmonics. Accordingly, as the tool 32 control the effect of each of the above embodiments determines the phase angle of the input current of the electric fan 15, specified through the element 31 control, harmonics can be effectively suppressed uniformly in such an electric vacuum cleaner 11.

In addition, the user can easily check the capacity of the electric fan 15 through the visual determination of the position adjusting portion 19, through which the electric vacuum cleaner becomes easy to handle.

In addition, because the tool 32 control formed by a digital circuit, it is possible to freely control the installation phase angle of the input current of the electric fan 15.

Moreover, in each of the above embodiments, since a change in the resistance value of the variable resistor 33 is smooth, no point bending, at least in the area corresponding to a predefined range of phase angle, harmonics which are generated with a value which is not less than the prescribed limit value L, it doesn't always have to be linear. That is, the resistance value of the variable resistor 33 can be changed, for example, by the so-called LOG curve or may be formed by the inflection point in the upper limit value, lower limit value or similar value of resistance in the area other than the area corresponding to the range pre is acceptable phase angle, harmonics which are generated with a value which is not less than the prescribed limit value L.

Variable resistor 33 can be located in any position, for example, on item 13 of the forming duct (part 23 manual control).

Valid, for example, instead of a known schema detection of zero crossing, was made the means 34 for determining the zero-crossing so that the voltage of the outlet e AC directly read by the tool 32, as well as the means 32 of the control was determined by the point of zero crossing. In particular, the tool 32 control subjects AC outlet e AC half-wave straightening, divides and receives the voltage e, performs digital conversion of the divided voltage and transmits it to the element 31 of the trigger control signal corresponding to the off time, the time when the divided voltage becomes equal to 0.

In addition, the tool 32 can be formed of an analog circuit using, for example, comparator, etc.

Despite the fact that have been described particular embodiments of these options for implementation were presented for illustrative purposes only and are not intended to limit the scope of the image is to be placed. Moreover, as described in this document new versions of the implementation can be implemented in many other forms; among other things, without departing from the invention in the form described in this document variants of implementation can be made of various exceptions, substitutions and changes.
