Description

[0001] This application is a divisional application of the Chinese patent application filed with the China Patent Office on May 19, 2017, with application number 201710358573.5 and invention name “Self-cleaning method of self-moving cleaning robot and self-moving cleaning robot”. Technical Field

[0002] The invention relates to a self-cleaning method of a self-moving cleaning robot and the self-moving cleaning robot, belonging to the technical field of small household appliance manufacturing. Background Art

[0003] The working mode of water vacuum cleaners currently on the market is usually to spray water on the ground and recycle sewage at the same time. However, after the work is completed, dust and other dirt will accumulate in the dust suction port / dirt cleaning port and air duct of the machine, which is very difficult for people to clean manually. Some places cannot even be cleaned, which brings inconvenience to users. In addition, at the end of the work, the pollutants remaining in the dust suction port or the dirt cleaning port will drip onto the work surface and cause secondary pollution.

[0004] The prior art with publication number CN101283894 discloses an automatic cleaning method and equipment. Page 4 of the specification discloses that an electric rotary mop cooperates with the front water spray head to spray water on the ground, and then the water suction port sucks away the sewage. The last line of page 5 explains that after the cleaning work is completed, the water inlet and the drainage interface are connected to the user's water inlet and drainage port respectively, and the cleaning machine automatically completes the cleaning of the inside of the machine body. Obviously, the above cleaning method requires user participation to change the original working mode of the automatic cleaning equipment, making the operation process more cumbersome.

[0005] The prior art with publication number CN106214079 discloses a self-cleaning cleaning machine, which can self-clean part of its own sewage recovery components. Page 36 of its specification states that after the cleaning machine is finished working, it can directly self-clean the external water supply pipe. Specifically, it is necessary to separate the cleaning brush from the external water supply pipe, and extend the external water supply pipe together with the water outlet pipe head to the self-cleaning pipe. Similarly, the above self-cleaning method also changes the original working mode of the cleaning method, which is cumbersome to operate and not conducive to long-term use. Summary of the invention

[0006] The technical problem to be solved by the present invention is to address the deficiencies in the prior art and to provide a self-cleaning method for a self-moving cleaning robot and a self-moving cleaning robot. Without changing the original working mode of the self-moving cleaning robot, the method can self-clean some stains remaining on the roller brush, roller brush cavity, water suction port, dust suction port and air duct position of the self-moving cleaning robot, and can prevent residual pollutants from dripping onto the working surface to cause secondary pollution. The method is simple to operate and easy to control, and can effectively realize the self-cleaning process of the self-moving cleaning robot.

[0007] The technical problem to be solved by the present invention is achieved through the following technical solutions:

[0008] A self-cleaning method for a self-moving cleaning robot, wherein the self-moving cleaning robot is provided with a working mode and a self-cleaning mode. When the self-moving cleaning robot needs to self-clean, the following steps are performed:

[0009] Step 100: Control the whole machine to enter a self-cleaning mode;

[0010] Step 200: The whole machine starts self-cleaning action;

[0011] Step 300: After the self-cleaning conditions are met, the self-cleaning mode ends.

[0012] Specifically, the step 100 specifically includes: the self-moving cleaning robot receives an input signal from a user and controls the entire machine to enter a self-cleaning mode.

[0013] Alternatively, the step 100 specifically includes: after the working mode of the self-moving cleaning robot ends, the whole machine is automatically controlled to enter the self-cleaning mode.

[0014] More specifically, the self-cleaning action in step 200 is a self-cleaning action in a small area, which is 1-3 square meters.

[0015] In order to meet different cleaning needs, the self-cleaning action in the small area includes an in-situ running action, an in-situ rotating action, or a spiral walking action.

[0016] In order to achieve a better cleaning effect, the self-cleaning action in step 200 specifically includes: increasing the suction force of the whole machine and / or increasing the water spray flow rate. Specifically, the suction force is increased to 1.5 times or more of the original; the water spray flow rate is increased to 1.5 times or more of the original.

[0017] In addition, the self-cleaning condition in step 300 is a time condition, that is, a self-cleaning time is preset in the whole machine control system, and the self-cleaning time is controlled by an automatic timing device arranged in the whole machine. After the preset time is reached, the self-cleaning mode is terminated.

[0018] The self-cleaning condition in step 300 may also be a water level condition, that is, a water level lower limit threshold is preset in the whole machine control system, and the self-cleaning mode is terminated after the actual water level reaches the threshold through a water level detection device provided in the whole machine.

[0019] The present invention also provides a self-moving cleaning robot, comprising a body, wherein the body is provided with a control system, a cleaning system and a walking system, wherein the control system is provided with a self-cleaning mode conversion control module, wherein the self-cleaning mode conversion control module is activated to enter the self-cleaning mode according to a user input signal, or the self-cleaning mode conversion control module automatically controls the self-moving cleaning robot to enter the self-cleaning mode and perform a self-cleaning action.

[0020] Specifically, the self-cleaning action is a self-cleaning action in a small area, and the small area is 1-3 square meters.

[0021] More specifically, the self-cleaning action in the small area includes an in-situ running action, an in-situ rotating action, or a spiral walking action.

[0022] In order to achieve a better cleaning effect, the self-cleaning action also includes: increasing the suction force and / or the water spray flow rate in the cleaning system.

[0023] To sum up, the present invention provides a self-cleaning method of a self-moving cleaning robot and a self-moving cleaning robot, which can self-clean some stains remaining on the roller brush, roller brush cavity, water suction port, dust suction port and air duct position of the self-moving cleaning robot without changing the original working mode of the self-moving cleaning robot, and can prevent residual pollutants from dripping onto the working surface to cause secondary pollution. The operation is simple and the control is convenient, and the self-cleaning process of the self-moving cleaning robot can be effectively realized.

[0028] Figure 1 FIG. 1 is a basic flow chart of the self-cleaning method of the cleaning machine of the present invention. Figure 1 As shown, the present invention provides a self-cleaning method of a self-moving cleaning robot, wherein the self-moving cleaning robot is provided with a working mode and a self-cleaning mode. When the self-moving cleaning robot needs to self-clean, the following steps are performed:

[0029] Step 100: Control the whole machine to enter a self-cleaning mode;

[0030] Step 200: The whole machine starts self-cleaning action;

[0031] Step 300: After the self-cleaning conditions are met, the self-cleaning mode ends.

[0032] Specifically, the step 100 specifically includes: the self-mobile cleaning robot receives the input signal from the user and controls the whole machine to enter the self-cleaning mode. In the actual operation process, different ways of inputting signals can be used according to different needs of users, for example: the whole machine can be controlled to enter the self-cleaning mode by the user manually pressing the self-cleaning mode button, the user can also control the whole machine to enter the self-cleaning mode by remote control, and of course, the user can also control the whole machine to enter the self-cleaning mode by a mobile phone installed with an operation APP. Alternatively, the step 100 can also specifically include: self-controlling the whole machine to enter the self-cleaning mode. The above-mentioned various operation processes can be controlled at any time in the working state of the self-mobile cleaning robot, for example: after the working mode of the self-mobile cleaning robot ends, or before the self-mobile cleaning robot returns to the charging station, the self-mobile cleaning robot can control itself to enter the self-cleaning mode; for example: after the self-mobile cleaning robot receives a user signal during work (such as edge walking operation, random walking operation or spiral walking operation), it can also enter the self-cleaning mode.

[0033] When the self-mobile cleaning robot enters the self-cleaning mode, the self-cleaning action begins. Specifically, in order to improve the self-cleaning efficiency, the self-cleaning action in step 200 is a self-cleaning action in a small area, and the small area is 1-3 square meters. In order to adapt to different cleaning needs, the self-cleaning action in the small area includes an in-situ running action or an in-situ rotation action or a spiral walking action. In order to better complete the self-cleaning operation and achieve the purpose of cleaning cleaning components, such as roller brushes, air ducts, etc., the self-cleaning action in step 200 specifically includes: increasing the suction of the whole machine and / or increasing the water spray flow rate. Specifically, the suction is increased to 1.5 times or more of the original; the water spray flow rate is increased to 1.5 times or more of the original.

[0034] That is to say, when the self-moving cleaning robot enters the self-cleaning mode, its movement mode can be an in-situ running action, an in-situ rotating action, or a spiral walking action. Specifically, the in-situ running action refers to the self-moving cleaning robot running in-situ without any movement, only relying on suction to absorb water, or only increasing the suction of the fuselage and / or increasing the water spray flow rate, and the body also does not move at all, and there is no movement trajectory. The in-situ rotating action refers to the clockwise or counterclockwise movement of the fuselage of the self-moving cleaning robot in a small area, and the movement trajectory can be a full circle or a semicircle. The spiral walking action refers to the walking action of the self-moving cleaning robot in a small area with a spiral line as the movement trajectory. The in-situ running action, in-situ rotating action, or spiral walking action can be divided into in-situ action and moving action, and usually only one of these two actions occurs. Since the self-moving cleaning robot maintains the original working mode after entering the self-cleaning mode, by adjusting the working state, it moves in a small area, or only increases the suction or increases the water spray flow rate at the same time, the operation method is simple and the self-cleaning efficiency is high.

[0035] In addition, the self-cleaning condition in step 300 is a time condition, that is, a self-cleaning time is preset in the whole machine control system, and the self-cleaning time is controlled by an automatic timing device set in the whole machine, and the self-cleaning mode ends after the preset time is reached. Usually, the preset time is 10-20 seconds.

[0036] In addition to the time condition, the self-cleaning condition in step 300 may also be a water level condition, that is, a water level lower limit threshold is preset in the whole machine control system, and the self-cleaning mode is terminated after the actual water level reaches the threshold through a water level detection device arranged in the whole machine.

[0037] Figure 2 This is a schematic diagram of the appearance structure of the self-moving cleaning robot of the present invention; Figure 3 FIG. 2 is a cross-sectional schematic diagram of the self-propelled cleaning robot of the present invention. Figure 2 and Figure 3As shown, the present invention also provides a self-moving cleaning robot 1000, including a body, wherein a control system, a cleaning system and a walking system (not shown in the figure) are arranged in the body, and a self-cleaning mode conversion control module is arranged in the control system, and the self-cleaning mode conversion control module starts to enter the self-cleaning mode according to a user input signal, or the self-cleaning mode conversion control module automatically controls the self-moving cleaning robot to enter the self-cleaning mode. Specifically, in order to improve the self-cleaning efficiency, the self-moving cleaning robot performs a self-cleaning action after entering the self-cleaning mode, and the self-cleaning action is a self-cleaning action in a small area, and the small area is 1-3 square meters. In order to adapt to different cleaning needs, the self-cleaning action in the small area includes an in-situ running action or an in-situ rotating action or a spiral walking action. In order to better complete the cleaning operation, the self-cleaning action specifically also includes: increasing the suction force and / or increasing the water spray flow rate in the cleaning system.

[0038] Embodiment 1

[0039] Combination Figures 1 to 3 As shown, the working process in this embodiment is as follows:

[0040] When the self-moving cleaning robot 1000 is cleaning the floor, the user finds that there are local heavy stains on the floor being cleaned, so he manually presses the self-cleaning mode button on the remote control to control the whole machine to enter the self-cleaning mode. At this time, the self-moving cleaning robot 1000 changes from the previous working walking state to spinning in place, cleaning a small area of ​​about 2.5 square meters. At the same time, the suction force of the self-moving cleaning robot 1000 is increased to 1.8 times the original, and the water spray flow rate is increased to 2 times the original. Since the water spray volume increases in the self-cleaning mode, and the lower limit threshold of the water level is preset in the control system of the whole machine, the water level detection device set in the whole machine detects that the actual water level reaches the threshold and ends the self-cleaning mode.

[0041] Embodiment 2

[0042] Combination Figures 1 to 3 As shown, the working process in this embodiment is as follows:

[0043] When the self-moving cleaning robot 1000 is cleaning the floor, the user finds that there is water accumulation in a part of the floor being cleaned, and controls the whole machine to enter the self-cleaning mode through a mobile phone installed with an operating APP. When the self-moving cleaning robot enters the self-cleaning mode, the self-moving cleaning robot 1000 moves in a small area of ​​2 square meters, and the suction force is increased to 3 times the original. Since the self-cleaning time is preset in the whole machine control system, the self-cleaning time is controlled by the automatic timing device set in the whole machine, for example: 12 seconds. When the preset time is reached, the self-cleaning mode ends.

[0044] Embodiment 3

[0045] Combination Figures 1 to 3 As shown, the working process in this embodiment is as follows:

[0046] After the working mode of the self-moving cleaning robot 1000 ends, the self-moving cleaning robot 1000 automatically controls the whole machine to enter the self-cleaning mode. At this time, the self-moving cleaning robot 1000 moves with a motion track in a small area of ​​3 square meters, and the suction force and water spray flow rate are increased to 2 times the original. The self-cleaning mode ends after 15 seconds of self-cleaning operation.

[0047] Embodiment 4

[0048] Combination Figures 1 to 3 As shown, the working process in this embodiment is as follows:

[0049] After the working mode of the self-mobile cleaning robot 1000 ends, the self-mobile cleaning robot 1000 automatically controls the whole machine to enter the self-cleaning mode. At this time, the self-mobile cleaning robot 1000 remains at the position when entering the self-cleaning mode, and the suction force and water spray flow rate remain unchanged. The self-cleaning mode ends after 20 seconds of self-cleaning operation.

[0050] To sum up, the present invention provides a self-cleaning method of a self-moving cleaning robot and a self-moving cleaning robot. Without changing the original working mode of the self-moving cleaning robot, the method can self-clean some stains including water stains, garbage, hair, etc. remaining on the roller brush, roller brush cavity, water suction port, dust suction port, and air duct of the self-moving cleaning robot, and can prevent residual pollutants from dripping onto the working surface to cause secondary pollution. The method is simple to operate and easy to control, and can effectively realize the self-cleaning process of the self-moving cleaning robot.
