Description

The present invention relates to a robot vacuum cleaner with an air purification function and a cleaning system, and more particularly, to a robot vacuum cleaner configured to clean the ambient air in a predetermined cleaning zone while cleaning the floor, and a cleaning system.

Despite the convenience that came with the invention of the vacuum cleaner, cleaning still remains a tedious household obligation, since the user has to move the vacuum cleaner himself to different places in the home. To solve this problem, work was undertaken to create a robot vacuum cleaner that can automatically move and carry out cleaning. Such a conventional robot vacuum cleaner automatically moves around a given area and draws dust and dirt from the surface without requiring user intervention. However, an ordinary robot vacuum cleaner does not have an air purification function, and it simply works by absorbing dust and dirt, thereby cleaning the surface. Recently, in connection with cases of SARS, many buyers have developed a deep interest in health problems and maintaining cleanliness and freshness of air. It is time to introduce the air purification function into the robot vacuum cleaner.

Figure 1 presents a schematic view of a conventional robot cleaner. As shown in FIG. 1, a conventional robot cleaner, i.e. having neither a function of air purification nor a function of air filtering, comprises a housing 7 and driving wheels 1 and driven wheels 2 located on the lower part of the housing 7. The upper part of the housing 7 has an antenna 3 for exchanging signals with a remote controller, and a distance sensor 4, located, respectively, in predetermined positions.

In addition, the housing 7 is equipped with a drive motor (not shown) for generating a suction force, and a dust collector (not shown). The suction force created by the drive motor is transmitted to the suction port 5 located in the lower part of the housing 7 so that dust and dirt from the surface to be cleaned are drawn into the suction port 5 under the influence of the suction force.

However, a robot vacuum cleaner of the indicated design collecting dust and dirt from the surface being cleaned has problems when moving along the area to be cleaned along a predetermined path. Firstly, since the robot vacuum cleaner has only a cleaning function by sucking dust and dirt from the surface to be cleaned, the buyer has to buy a separate air cleaning device in order to add the air cleaning function to the robot vacuum cleaner. Secondly, if dust from the surface is not completely absorbed into the suction port 5 of the robot vacuum cleaner that does not have an air purification function, the air in the cleaning zone is polluted, which leads to potential harm to the user due to polluted air.

Thus, there is still an unmet need to address the above disadvantages and miscalculations.

The present invention was created to solve the above problems of the prototype. Accordingly, the technical task of the present invention was the creation of a robot vacuum cleaner and cleaning system that clean the surrounding air in the cleaned area during surface cleaning.

This technical application is solved due to the fact that the robot vacuum cleaner according to the present invention includes a housing, a drive, driving wheels located in the lower part of the housing, a dust suction device made in the housing for drawing dust from the surface to be cleaned, an air cleaning device made in case, for drawing in air with dust from the cleaned area, purifying the air and discharging purified air, and a controller located in the case for controlling the drive and the air purification device, while Lena has a cover that forms the appearance of a robot vacuum cleaner, and the air purifier contains an intake system drive for drawing air with dust from the cleaning zone, a suction port connected to one side of the housing cover, an exhaust port connected to the other side of the housing cover, a cleaning path air in fluid communication with the suction port and the outlet port, and filters located in the air purification path to clean the drawn-in air.

Preferably, the suction port is formed on one side of the front of the housing cover.

Preferably, the outlet port is formed on the other side of the front of the housing cover.

Preferably, the suction port is formed on one side of the upper portion of the housing cover.

Preferably, the outlet port is formed on the other side of the front of the lid body.

Preferably, the outlet port is formed on the other side of the upper portion of the lid body.

Preferably, the suction drive is located in the air purification path for drawing in air.

Preferably, the filters comprise a first filter that filters out relatively large dust particles from the drawn in air and a second filter that filters out small particles and minor odors from the air.

The above technical problem is also solved due to the fact that the robot vacuum cleaner system according to the invention comprises a drive for driving wheels, a dust suction device for drawing dust from a surface to be cleaned, and a controller for controlling a drive and a dust suction device, further comprising an air cleaning device controlled by a controller, which is arranged to carry out cleaning by a device for suctioning dust and air purification by a device for cleaning air simultaneously or selectively and in The second air purification device comprises a suction system drive for drawing dusty air from a predetermined cleaned area, a suction port through which air is drawn in, an exhaust port through which purified air is discharged, and at least one filter for purging the drawn air, and the system made with the possibility of drawing air through the suction port, filter cleaning and exhaust through the exhaust port when the controller actuates the suction system.

The following is a more detailed description of a robot cleaner and a robot cleaner system according to the present invention with reference to the accompanying drawings.

As shown in FIGS. 2-5, the robot cleaner 10 includes a housing 12, a housing cover 11 connected to the housing 12 to form the exterior of the robot cleaner 10, a dust suction device 16, and a drive device 20. The robot cleaner also includes an upper chamber 30, a front camera 32, an obstacle sensor 34, an air purifier 60, a controller 40, a storage device 41, and a transceiver device 43. Position I denotes the direction the robot cleaner 10 is moving against. 10. Suction device 16 dust is made on the housing 12 for drawing in dusty air and, thereby, to collect dust from the surface to be cleaned. The dust suction device 16 may take a variety of well-known forms. For example, the dust suction device 16 may have a suction motor (not shown) and a dust collecting chamber drawn in through the suction port, or a suction tube formed opposite the surface being cleaned and operating from the suction motor.

The drive 20 contains two driven wheels 21 located at the front on both sides of the housing 12, two driving wheels 22 located at the rear on both sides of the housing 12, a pair of electric motors 24 for rotating the two rear wheels 22, respectively, and a timing belt 25 for transmitting drive force from the rear wheels 22 to the front wheels 21. In addition, the drive 20 is configured to independently rotate the electric motors 24 clockwise or counterclockwise in accordance with the control signal from the controller 40. The direction of movement of the robot EWOS 10 can be changed by rotating the motors 24 with different frequencies. The front camera 32 is located on the housing 20 for photographing the images in front and outputting the received images to the controller 40. The upper camera 30 is located on the housing 12 for photographing the images from above and outputting the images on the controller 40. In another embodiment, a fish-like lens is used in the upper camera 30 eye "(not shown). A fisheye lens is disclosed in Korean Patent Applications No. 1996-7005245 and 1994-22112 and is manufactured by various optical manufacturers, therefore, a detailed description thereof is omitted.

The obstacle sensors 34 are located on the periphery of the housing 12 at predetermined intervals for emitting signals to the outside and for receiving reflected signals. The obstacle sensors 34 may be ultrasonic sensors for emitting and receiving ultrasound. Obstacle sensors 34 are also used to measure the distance to an obstacle or wall.

As shown in FIG. 4, an air purification device 60 is located on one side of the housing 12 for drawing air from the zone to be cleaned and for air purification. The air purification device 60 includes a suction system drive 61, a suction port 63 connected to one side of the housing cover 11, an exhaust port 65 connected to the other side of the housing cover 11, an air purification path 67 and filters 69. The suction system drive 61 creates a suction force to draw in air and dust from the cleaning zone. The drive 61 of the suction system can be installed in the path 67 of the air purification and creates a suction force together with a suction motor (not shown), which creates a suction force for the dust suction device in the housing 12.

Accordingly, the suction system drive 61 can be configured either in conjunction with a drive motor (not shown) or separately from the drive motor to create a suction force in the air purification device 60. The suction drive 61 may consist of an electric motor and a fan.

The suction port 63 is formed on one side of the front of the housing cover 11 or on one side of the side of the housing cover 11. An outlet port 65 is formed on the other side of the front of the housing cover 11 or on the other side of the side of the housing cover 11. As shown in FIG. 2, the suction port 63 is formed on one side of the front of the housing cover 11, while the exhaust port 65 is formed on one side of the rear of the housing cover 11. The positions at which the suction port 63 and the outlet port 65 are formed may vary. For example, a suction port 63 may be formed on one side of the front of the housing cover 11, while an outlet port 65 may be formed on one side of the upper part of the housing cover 11, as shown in FIG. In addition, there may be at least two suction ports 63 and at least two exhaust ports 65. In this embodiment, each suction port 63 and exhaust port 65 may be located independently of the air purification path 67 or may be connected to the air purification path 67.

The air purification path 67 is in fluid communication with the suction port 63 and the exhaust port 65, so that air drawn through the suction port 63 by the suction system drive 61 exits through the exhaust port 65, passing through the air purification path 67.

Provided that the suction port 63 communicates with the outlet port 65, this communication line may take various forms, for example, a straight line or a curved line.

Filters 69 clean the air drawn through the suction port 63. Filters 69 include a first filter 71 and a second filter 73. The first filter 71 filters out relatively large dust particles, and the second filter 73 filters out relatively fine dust particles and small odors from the air, from which large dust. In another embodiment, the second filter 73 may comprise a high-performance dry air filter for filtering the smallest bacteria and viruses, fungi, house dust and animal dust, which can cause respiratory and allergic diseases in humans. The second filter 73 may use a common deodorizing filter to eliminate various odors.

The controller 40 processes the signals received through the transceiver device 43 and accordingly controls the various components. The robot cleaner 10 may further comprise a keyboard (not shown). In this embodiment, a keyboard (not shown) is formed on the housing 12 and contains a plurality of keys for setting the functions of the robot cleaner, and the controller 40 processes the key signals inputted from a keyboard (not shown).

The controller 40 includes a dust suction device 16 and a drive 20, and instructs the robot cleaner 10 to clean the cleaning zone. The controller 40 also simultaneously controls the air purification device 60. Including the drive 20 and at the same time the air purification device 60, but not including the dust suction device 16, the robot vacuum cleaner 10 can only perform the function of air purification, moving around the cleaned area.

A storage device 41 stores images photographed by the upper camera 30 so that the controller 40 can calculate the location and direction of movement. The transceiver 43 transmits data to an external device 80 through a transmitter (not shown) installed in the controller 40 (not shown), and transmits signals received from the external device 80 to the controller 40. The external device 80 may be a wireless relay device (not shown ) or a remote controller (not shown) through which data is transmitted and received. In this embodiment, the external device 80 is a remote controller.

The following is a detailed description of the operation of the robot vacuum cleaner system having the air purification function of the described construction. When an operation command is received from the external device 80, the robot cleaner 10 receives this command through the transceiver device 43. Depending on whether the command was received for cleaning or air purification, the controller 40 includes a drive 20, a dust suction device 16, or a device 60 air purification. Accordingly, automatically crossing a predetermined area, the robot cleaner 10 performs cleaning using the dust suction device 16 and purifies the air using the air purification device 60, or selectively performs either cleaning or air cleaning.

When the controller 40 turns on the actuator 61 of the suction system, air is drawn in through the suction port 63, cleaned by filters 69 of the air purifier 60, and discharged through the exhaust port 65. When a signal to stop the operation of the actuator 20 is input through an external device 80, the robot vacuum cleaner stops at the specified location but continues to clean the air. As described above, the robot vacuum cleaner 10 performs cleaning and air purification simultaneously or selectively. Since the above robot vacuum cleaner and the robot vacuum cleaner system for cleaning the surface have an air purification function, the user does not need to buy a separate air cleaner, which gives him an additional advantage. In addition, since the robot vacuum cleaner cleans and refreshes the air in a given cleaning zone, it helps to create a fresher environment in the home.

The above options and advantages are illustrative and should not be construed as limiting the present invention. The description of the present invention is illustrative and does not limit the scope of the formula. Professionals understand the various possible alternatives, changes and modifications. In the claims, the “means + function” clauses are intended to encompass the described structures performing the above function, and not only structural equivalents, but also equivalent structures.
