The robot cleaner directs the intake duct so as to ensure the removal of foreign particles from the surface being cleaned. Typically, the robot cleaner moves and sucks inside the dust or the dirt on the floor, through the suction aperture and produces a filtered air. Therefore, the dust outside the zone of immediate treatment, remains on the surface being cleaned. The dust on the floor can rise into the air and dissipate in the air, thus causing the need for ventilation for some time after cleaning is completed. In addition, for air purification, the user has to purchase additional generators ions, at least one per paragraph is operating. If you supply each room generators ions, it will lead to too high costs.

The reference character 'I' denotes the front side of the robot cleaner.

The suction device 16 is mounted on the housing 12 of the cleaning device and is designed to collect dust from the opposite surface of the floor by suction air. The suction device 16 may be constructed in accordance with various well known ways. For example, the suction device 16 may include a motor to create a suction force (not shown) and a dust collector for collecting dust which is sucked in through the inlet or suction opening, which is addressed to the floor, due to the actuation of the electric motor, designed to create a suction force.

The actuator 20 includes two auxiliary wheels 21 mounted on both front sides, two leading wheels 22 mounted on both rear sides, two of the drive motor 24, designed to bring the rotation of the respective two rear wheels 22, and means 25 for transmitting the driving force, designed to transmit the driving force from the rear wheels 22 of the front auxiliary wheels 21.

In this embodiment, the means 25 for transmitting the driving force is made in the form of a synchronous belt or the willow for torque transmission. In addition, the actuator 20 is to ensure that the motor 24 to rotate independently from each other, in the direction of clockwise or counterclockwise in accordance with a control signal from the control unit 40. The direction of movement of the robot cleaner is changed by varying the number of revolutions per minute of the respective drive motors 24.

Front camera 32 mounted on the housing 12 of the cleaning device and is intended to capture images of objects in front of, and transfer photographed image control device 40. The upper chamber 30 is installed on the housing 12 of the cleaning device and is intended for photographing the image of the ceiling and transmission photographed image control device 40. Preferably in the upper chamber 30 is used an ultra-wide angle lens-type "fish eye" (with an angle field of 180° and more) (not shown). The design of ultra-wide-angle lens type fisheye disclosed in the publication of the patent Korean 1996-7005245, the publication of the patent Korean 1997-48669 and publication of the patent Korean 1994-22112. Ultra-wide angle lens-type "fish eye" comes on the market, several manufacturers lenses. Therefore, a detailed description is not given.

The sensors 34 for detection is of obstacles are located at a predetermined distance from each other on a circumferential periphery of the housing 12 of the cleaning device and transmits the signal to the external space and reception of the reflected signal. Alternatively, as a sensor 34 for detecting obstacles can be used an ultrasonic sensor that emits an ultrasonic wave and receives the reflected ultrasonic wave. The sensor 34 for detecting obstacles is also used to determine the distance to obstacles. As a sensor (not shown) to determine the length of travel, which is connected with the control device 40 may be used a sensor to detect rotation, which determines the rotational speed of the drive wheels 22 or the rotational speed of the auxiliary wheels 21, expressed in revolutions per minute. Sensor for detecting the rotation may be a code sensor that detects the rotational speed of the respective drive motors 24, expressed in revolutions per minute.

As shown in figure 4, the device 11 for generating negative ions includes flow fan 45, the motor 47 of the rotational motion, the generator 49 of negative ions, the outlet channel 57, item 59 lattice part and multiple filters 51. Direct-flow fan 45 is mounted on one side of the housing 12 of the cleaning device and is designed to release air from the interior of the housing 12 of the cleaning device. Power to the motor 47 of the rotational motion on the W from the power supply (not shown), and the motor 47 of the rotational movement causes the rotation of the direct-flow fan 45 for messages torque effort to release air from the housing 12 of the cleaning device. The generator 49 generates negative ions negative ion of the air, which is produced by direct-flow fan 45. Generated negative ion is produced together with the air, thereby cleaning the surrounding air.

Negative ion includes tiny invisible particles that have electric charge. An ion is an atom with an electric charge, which represents an element or molecule with an electrical charge that represents a set of atoms. Negative ion is an ion that has a negative charge. In the case when the stable molecule is electrically charged by certain particles and thus electrified, the state of a molecule called negative ionization. Oxygen and chlorine is likely to be negative ionization. When an electron "jumps" from the surface of the substance, the emission of electrons. The negative ion generator is a device designed for ionization of surrounding substances by generating a large number of electrons on the basis of this is about principle. Therefore, by supplying a negative voltage of approximately one thousand Volts, the electrons, which carry a negative charge, are emitted into the air at high speed by means of corona discharge, that is, by breaking down the insulation in the air, with enough energy for ionization to ionize air negative ions.

The generator 49 of negative ions is an industrially produced and available on the market a negative ion generator that generates negative ions to clean the air and provides fresh air within a defined space. The outlet channel 57 is a channel for the release of air in the body of the robot cleaner. Item 59 lattice part is attached to the end of the discharge channel 57 and has a lot of holes formed therein. The air passing through the exhaust channel 57, is produced in a predetermined space through the outlet 63, which is formed on one side of the cover 14 of the housing and the position of which corresponds to the location of the element 59 lattice part.

As shown in figure 5, item 59 lattice part can be grounded to the housing 12 of the cleaning device through the grounding device 65. This is done to prevent "sticking" of negative ion, g is narisovannogo generator 49 of negative ions, the element 59 lattice part, when a positive ion is generated at the element 59 lattice part that could lead to a decrease in the efficiency of generation of negative ion. For the same reason, the surface of the outlet 63 may be formed of an antistatic polymer when the grounding element 59 lattice part on the housing 12 of the cleaning device.

Many filters 51 are installed on one side of the element 59 lattice part and are designed to filter air, produced by the exhaust channel 57, and include the first filter 53 and the second filter 55. The first filter 53 filters out dust from sucked air, consisting of particles of large size. The second filter 55 filters out fine dust particles of the air passed through the first filter 53, and eliminates odors. Preferably, if the second filter 55 is formed from a high-performance dry air filter designed to filter out particles which are major causes of respiratory diseases and allergies, that is, mold, house dust, dandruff animals and viruses. Alternatively, the second filter 55 may be a conventional filter to eliminate odors. A filter for removing odors cleans the air by removing different smells.

Saponi the surrounding device 41 memorizes and stores the image of the ceiling, photographed by the upper camera 30, and facilitates the control device 40 in determining data relating to the location of the robot cleaner, or data relating to the movement of the robot cleaner. Transmitting-receiving device 43 transmits data to be transmitted to the external device 80 via a transceiver (not shown)mounted in the control unit 40, and transmits the signal from an external device 80 received by the transceiver (not shown), the control device 40. The external device 80 preferably is a device for routing and transmitting it wirelessly. The controller 40 processes the signal received by transceiver device 43, and controls the respective components in accordance with the received signal. In that case, if the body 12 of the cleaning device is a key input device (not shown), and this is a keyboard input device, a plurality of keys for setting functions of the robot cleaner, the control unit 40 processes the signals from the keys entered via a keyboard input device.

The control device 40 controls the actuator 20 to provide moving in the working area in accordance with a predetermined path of movement, and ensure that the AET entry in the storage device 41 of the card images of the ceiling, obtained on the basis of the image photographed by the upper camera 30. Alternatively, when receiving a command transmitted via a wireless connection from keyboard input or from the outside, the control unit 40 retrieves a map image before performing the work of cleaning. Through the use of image maps when performing tasks in the work process control device 40 detects the location of the robot cleaner. When the input signal of the execution request job received through a wireless network from a keyboard input device or from the outside, the control device 40 determines the current position of the robot cleaner by comparing maps images with current images coming from the upper chamber 30 and the front camera 32, and controls the actuator 20 so as to provide movement of the detected position, which corresponds to the trajectory at a given destination. The signal of execution request includes the task to perform cleaning or monitoring by cameras 30, 32.

While moving along a given trajectory to the destination control device 40 calculates the error of the length of the move by using the length of the move, a particular code sensor, and the current situation, which defined the but by comparing the photographed image with the stored card images. The control device 40 controls the actuator 20 so as to provide tracking of the trajectory to the destination due to correction of errors are calculated. When the robot cleaner 10 operates, the control device 40 controls the suction device 16 and a device 11 for generating negative ions in accordance with the request signal to perform work at the same time. In particular, direct-flow fan 45 device 11 for generating negative ions is driven by power supplied from a power supply (not shown)provided in the housing 12 of the cleaning device. The air produced by the exhaust channel 57, is cleaned using a variety of filters 51, and when releasing the cleaned air passes through the generator 49 of negative ions. Therefore, the ionized air produced in the predetermined area being cleaned.

In addition, dust or dirt on the floor, absorbed in the body 12 of the cleaning device by an electric motor (not shown)designed to create a suction force, and the suction pipe, which are manufactured cleared the air. As a result, in the process of moving in a predetermined area of the robot cleaner cleans the floor, releasing the cleaned air and negative ions in the air or selectively or simultaneously.

When p is lovatelli enters a command to the external device 80, initiating termination of operation of the actuator 20, the robot cleaner 10 remains in a certain position and continues to perform the job for cleaning the floor or the generation of negative ions. When you shut down for cleaning or generating negative ions, the user enters a command to terminate the operation of the entire device through the external device 80. Accordingly, the controller 40 of the robot cleaner 10 issues a command to stop execution of the work and ensures the return of the robot cleaner 10 to the original position. As described above, the robot cleaner 10, is equipped with a negative ion generator, automatically moves over the area being cleaned, performing cleaning by suction through the use of suction devices 16 and air cleaning by using a device 11 for generating negative ions simultaneously or selectively.

As described above, the robot cleaner according to the present invention performs the cleaning of the floor and generates negative ions in a predetermined zone with simultaneous automatic movement with a predetermined area. Accordingly, the robot cleaner is a tool that contributes to the conservation of human health and refreshing environment in the house. In addition, the robot cleaner according to the present invention I have is cheap, because the user does not need to buy a separate generator of negative ions, and easy to use thanks to automatic operation.

In addition, the element 59 lattice part made of antistatic polymer and grounded to the housing 12 of the cleaning device to save the element 59 lattice part is electrically neutral or negatively charged at all times. Accordingly, to prevent "sticking" of negative ion generated by the generator 49 negative ions to the surface of the element 59 lattice part.
