Description

Technical Field

[0001] This application relates to the field of cleaning device technology, and in particular to an automatic water tank cleaning device and its exhaust control method. Background Technology

[0002] With the development of computer technology, robotics technology has also advanced rapidly. Currently, underwater robots are increasingly widely used in various fields, assisting people in underwater operations, including underwater cleaning, underwater exploration, and underwater tourism. Robots used for underwater cleaning, such as automatic pool cleaning devices, need to descend to the bottom of the pool to clean it. However, due to gaps in the body of these devices, many air bubbles can accumulate inside during descent. These air bubbles increase the buoyancy of the automatic pool cleaning device, thus affecting its descent speed. Summary of the Invention

[0003] According to a first aspect of this application, an automatic water tank cleaning device is provided, the device comprising:

[0004] The shell has a water inlet at its upper part;

[0005] A filter device is installed inside the housing. The filter device is capable of filtering the water flow entering the water inlet and storing the filtered waste.

[0006] A water ingress detection unit is provided, which is capable of detecting whether the automatic cleaning device for the water tank has been submerged in water.

[0007] An inlet baffle is provided in the area where the water inlet is located. The inlet baffle includes a first end and a second end, and the second end is rotatable relative to the first end, thereby opening or closing the inlet baffle. The automatic cleaning device for the pool has two operating modes: a surface cleaning mode and a sinking venting mode. In both the surface cleaning mode and the sinking venting mode, the inlet baffle is in the open state.

[0008] According to the automatic water tank cleaning device provided in this application, the device further includes:

[0009] A water-permeable barrier is provided in the area where the water inlet is located, wherein...

[0010] In the aforementioned surface cleaning mode, the permeable barrier is in the open state, thereby allowing water carrying debris to enter the surface inlet; and

[0011] In the sinking and venting mode, the water-permeable barrier is in a closed state, thereby preventing the debris in the filter device from flowing out of the water surface inlet.

[0012] According to the present application, an automatic water tank cleaning device further includes a driving device, wherein the water-permeable blocking member or the water inlet baffle can be opened and closed by the driving device.

[0013] According to the present application, an automatic water tank cleaning device is provided, wherein the inlet baffle can be opened by the water flow into the inlet of the water surface.

[0014] According to the present application, an automatic water tank cleaning device is provided, which further includes a control unit, wherein the control unit is capable of receiving the detection signal of the water inlet detection unit, and controlling the automatic water tank cleaning device to enter the water surface cleaning mode or the sinking air venting mode based on the detection signal.

[0015] According to the present application, an automatic pool cleaning device is provided, which further includes a bottom contact detection unit. The bottom contact detection unit can detect whether the automatic pool cleaning device has sunk to the bottom of the pool. If the bottom contact detection unit detects that the automatic pool cleaning device has sunk to the bottom of the pool, the bottom contact detection unit triggers the automatic pool cleaning device to enter the bottom cleaning mode.

[0016] According to the present application, an automatic water tank cleaning device is provided, wherein the water-permeable blocking member is disposed on the inner or outer side of the water inlet baffle.

[0017] According to the present application, an automatic water tank cleaning device is provided, wherein the water-permeable blocking component is a mesh baffle or a grid baffle.

[0018] According to the present application, an automatic water tank cleaning device is provided, wherein the first end is disposed on the housing.

[0019] According to a second aspect of this application, a method for controlling the venting of an automatic water tank cleaning device during water immersion is provided, wherein the venting control method includes controlling the automatic water tank cleaning device described above to enter a venting mode during venting, and opening the water inlet baffle in the venting mode.

[0020] According to the present application, an automatic water tank cleaning device is provided with a method for controlling the venting when it sinks into water. The venting control method further includes: determining whether the automatic water tank cleaning device has sunk to the bottom of the water tank; if the automatic water tank cleaning device has sunk to the bottom of the water tank, controlling the automatic water tank cleaning device to enter the bottom cleaning mode; in the bottom cleaning mode, the inlet baffle is closed, and water suction is performed through the bottom inlet of the automatic water tank cleaning device.

[0021] The embodiments described in this application have the following beneficial effects:

[0022] The automatic water cleaning device of this application includes a housing with a water inlet, a filter, a water inlet detection unit, and an inlet baffle. When the automatic water cleaning device cleans the water surface, opening the inlet baffle allows the filter to clean the water surface smoothly. When the automatic water cleaning device sinks, opening the inlet baffle allows the device to quickly expel the gas inside the device, thereby increasing the sinking speed of the automatic water cleaning device.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] This application provides an automatic water tank cleaning device. Figure 1 This is a partial structural schematic diagram of the automatic water tank cleaning device provided in this application. Figure 1 As shown, the device includes: a housing 101, a filter device 102, a water inlet detection unit (not shown), and a water inlet baffle 103. A water surface inlet is provided on the upper part of the housing 101. The filter device 102 is disposed inside the housing 101 and can filter the water entering the water surface inlet and store filtered debris. The water inlet detection unit can detect whether the automatic water cleaning device has water in it. The water inlet baffle 103 is disposed in the area where the water surface inlet is located. The water surface inlet baffle 103 includes a first end 104 and a second end 105. The second end 105 can rotate relative to the first end 104, thereby opening or closing the water surface inlet baffle 103. The automatic water cleaning device has two operating modes: a surface cleaning mode and a sinking venting mode. In both the surface cleaning mode and the sinking venting mode, the water inlet baffle 103 is in the open state.

[0031] Specifically, the aforementioned automatic pool cleaning device can move and clean within a pool-shaped structure, such as a swimming pool, water storage tank, spa pool, water tank, or water reservoir. The automatic pool cleaning device can be a device such as an automatic cleaning system or a pool cleaning robot, capable of cleaning the pool-shaped structure. This application does not limit the specific presentation of the automatic pool cleaning device or the pool-shaped structure, as long as the principle of this application is achieved. It is understood that when cleaning the pool, the automatic pool cleaning device includes cleaning the waterline, the water surface, and the bottom of the pool. When cleaning the bottom of the pool is required, the automatic pool cleaning device needs to descend to the bottom of the pool to perform the cleaning.

[0032] The structure of the automatic water tank cleaning device will be described in detail below with reference to the attached drawings. Figure 1As shown, the automatic water tank cleaning device may include a housing 101, a filter device 102, a water inlet detection unit, and a water inlet baffle 103. The housing 101 has a water surface inlet at its upper part, through which water from the tank enters the automatic water tank cleaning device. The filter device 102 filters the water entering the device and stores any filtered debris. The clean water filtered by the filter device 102 is discharged from the drain outlet of the automatic water tank cleaning device back into the tank. This process is repeated to clean the water surface in the tank.

[0033] The water ingress detection unit can be located inside the housing 101 of the automatic pool cleaning device, or at a predetermined position on the surface of the housing 101. This water ingress detection unit can detect whether the automatic pool cleaning device is submerged in water. If the water ingress detection unit detects that the automatic pool cleaning device is submerged in water, the automatic pool cleaning device can enter a surface cleaning mode, a sinking air venting mode, and a bottom cleaning mode. The surface cleaning mode, the sinking air venting mode, and the bottom cleaning mode will be described below.

[0034] For example, the water ingress detection unit may include a sensor and a data detection module. The sensor may be a water outlet sensor, a pressure sensor, an ultrasonic sensor, a laser sensor, etc. The sensor can acquire the data to be detected and send the data to the data detection module, which then determines whether the automatic cleaning device for the pool has entered the water based on the data.

[0035] The description of sensor types above is merely exemplary, and this application does not impose specific limitations, as long as the technical principles of this application can be achieved. For example, the water ingress detection unit can also detect the current and / or power of the water pump in the automatic water cleaning device. When the automatic water cleaning device is started but not filled with water (e.g., when the automatic water cleaning device is warming up), the water pump in the automatic water cleaning device has no load, so the water pump only has a small current and operates with a small power. However, after the automatic water cleaning device is placed on the water surface, water will enter the interior of the automatic water cleaning device. At this time, the water pump has a load, and the current and power will change, increasing. Based on this principle, by detecting the current and / or power of the water pump, it is possible to determine whether the automatic water cleaning device has been filled with water.

[0036] An inlet baffle 103 may also be provided at the area where the water inlet is located. The inlet baffle 103 may include a first end 104 and a second end 105. The second end 105 is rotatable relative to the first end 104. By rotating the second end 105 relative to the first end 104, the water inlet baffle 103 can perform an opening or closing action. In one embodiment, the first end 104 is disposed on the housing 101.

[0037] The opening of the inlet baffle 103 refers to the rotation of the second end 105 of the inlet baffle 103 relative to the first end 104, thereby opening the inlet baffle 103 (e.g., the second end 105 moves away from the housing 101), allowing water to flow into the automatic water tank cleaning device. The closing of the inlet baffle 103 refers to the rotation of the second end 105 of the inlet baffle 103 relative to the first end 104, thereby closing the inlet baffle 103 (e.g., the second end 105 contacts or engages with the housing 101), thereby preventing water from flowing into the automatic water tank cleaning device. The above description of opening and closing is merely exemplary and is not intended to limit the meaning of these two actions. Those skilled in the art can select the opening and closing actions of the inlet baffle 103 based on the principles of this application, as long as the technical principles of this application are achieved.

[0038] The automatic pool cleaning device can operate in two modes: a surface cleaning mode and a sinking venting mode. The inlet baffle 103 needs to be open when the automatic pool cleaning device enters the surface cleaning mode (i.e., when it is performing surface cleaning), allowing water in the pool to smoothly enter the device through the surface inlet for filtration by the filter 102. The inlet baffle 103 also needs to be open when the automatic pool cleaning device enters the sinking venting mode (i.e., when it is sinking in the pool), allowing gas in the device to be smoothly discharged through the inlet baffle 103 from the surface inlet during sinking, enabling the device to sink quickly in the pool.

[0039] The above embodiments have the following beneficial effects:

[0040] The aforementioned automatic water tank cleaning device includes a housing 101 with a water inlet, a filter device 102, a water inlet detection unit, and an inlet baffle 103. When the automatic water tank cleaning device cleans the water surface, opening the inlet baffle 103 allows the filter device 102 to smoothly clean the water surface of the tank. When the automatic water tank cleaning device sinks, opening the inlet baffle 103 allows the automatic water tank cleaning device to quickly expel the gas inside the device during the sinking process, thereby increasing the sinking speed of the automatic water tank cleaning device.

[0041] In one embodiment, Figure 2 This is a structural schematic diagram of the inlet baffle 103 and the water-permeable blocking component 106 provided in this application. Figure 2 As shown, the device further includes a water-permeable barrier 106, which is disposed in the area where the water surface inlet is located. In the water surface cleaning mode, the water-permeable barrier 106 is in an open state, thereby allowing water carrying garbage to enter the water surface inlet; and in the sinking and venting mode, the water-permeable barrier 106 is in a closed state, thereby preventing garbage in the filter device 102 from flowing out of the water surface inlet.

[0042] Specifically, the automatic water cleaning device may further include a water-permeable barrier 106, which is located in the area of ​​the water inlet. The water-permeable barrier 106 allows water to flow smoothly but blocks debris from passing through. Therefore, when the automatic water cleaning device is in surface cleaning mode, the water-permeable barrier 106 is open, and both the water-permeable barrier 106 and the inlet baffle 103 are open, allowing water containing debris to flow smoothly into the automatic water cleaning device for filtration by the filter device 102. When the automatic water cleaning device is in sinking and venting mode, the water-permeable barrier 106 is closed, and the inlet baffle 103 is open while the water-permeable barrier 106 is closed, allowing gas to escape smoothly from the automatic water cleaning device. Debris in the automatic water cleaning device is prevented from being backflowed into the water by the water-permeable barrier 106.

[0043] The water-permeable barrier 106 includes a first end and a second end. The first end of the water-permeable barrier 106 is connected to the housing. The second end of the water-permeable barrier 106 is rotatable relative to the first end of the water-permeable barrier 106. By rotating the second end relative to the first end, the water-permeable barrier 106 can perform an opening or closing action.

[0044] The opening of the permeable barrier 106 refers to the rotation of the second end of the permeable barrier 106 relative to the first end, thereby opening the permeable barrier 106 (e.g., the second end of the permeable barrier 106 moves away from the housing), allowing debris in the water to flow into the automatic water tank cleaning device. The closing of the permeable barrier 106 refers to the rotation of the second end of the permeable barrier 106 relative to the first end, thereby closing the permeable barrier 106 (e.g., the second end contacts or engages with the housing), preventing debris in the automatic water tank cleaning device from flowing into (i.e., backflowing) into the water tank, and allowing gas in the automatic water tank cleaning device to pass through the permeable barrier 106 and the inlet baffle 103 and exit from the water surface inlet. The above description of opening and closing is merely exemplary and is not intended to limit the meaning of these two actions. Those skilled in the art can select the opening and closing actions of the permeable barrier 106 based on the principles of this application, as long as the technical principles of this application are achieved.

[0045] exist Figure 2 In the illustrated embodiment, both the inlet baffle 103 and the water-permeable blocking member 106 can be oriented in the same direction (i.e., Figure 2 (As shown in the left direction) Open, in Figure 2 In the scenario shown, the inlet baffle 103 is located on the outside, and the water-permeable barrier 106 is located on the inside. In other words, the water-permeable barrier 106 is closer to the interior of the automatic water tank cleaning device (e.g., closer to the filter device 102) than the inlet baffle 103.

[0046] exist Figure 2 In the illustrated embodiment, the opening direction of the permeable barrier 106 may also be different from the opening direction of the inlet baffle 103. In other words, the inlet baffle 103 opens towards... Figure 2 The left-side opening is shown, while the water-permeable barrier 106 is oriented towards... Figure 2 The right-side direction is shown.

[0047] In another embodiment, the inlet baffle 103 may be located on the inner side, and the water-permeable barrier 106 may be located on the outer side. In other words, the inlet baffle 103 is closer to the interior of the automatic water tank cleaning device (e.g., closer to the filter device 102) than the water-permeable barrier 106. In this embodiment, both the inlet baffle 103 and the water-permeable barrier 106 may open in the same direction, i.e., both open towards the direction of the filter device. The opening direction of the water-permeable barrier 106 may also be different from that of the inlet baffle 103. That is, the water-permeable barrier 106 opens away from the filter device 102, while the inlet baffle 103 opens towards the direction of the filter device.

[0048] The above description of the positional relationship and opening direction of the inlet baffle 103 and the water-permeable blocking component 106 is merely exemplary. Those skilled in the art can selectively set the positional relationship and opening direction of the two according to actual needs, as long as the technical principle of this application can be achieved.

[0049] The structure of the permeable barrier 106 can be configured as needed. In one embodiment, the permeable barrier 106 is a mesh baffle or a grid baffle. The permeable barrier 106 can also be a barrier such as a mesh or a diamond mesh, which serves to allow air to pass through and block debris.

[0050] The above embodiments have the following beneficial effects:

[0051] By installing a permeable barrier 106 at the water inlet of the automatic water cleaning device, during the descent of the automatic water cleaning device, the gas in the automatic water cleaning device can be smoothly discharged through the water inlet baffle 103 and the permeable barrier 106 by opening the water inlet baffle 103 and closing the permeable barrier 106. In addition, the permeable barrier 106 can prevent the garbage in the automatic water cleaning device from being ejected back into the water pool, thereby increasing the descent rate of the automatic water cleaning device while preventing the water in the water pool from being contaminated by the garbage in the automatic water cleaning device.

[0052] In one embodiment, the device further includes a drive mechanism, wherein the permeable barrier 106 and / or the inlet baffle 103 can be opened and closed by the drive mechanism.

[0053] Specifically, the automatic cleaning device for the water tank may further include a driving device that can drive the opening and closing of the permeable barrier 106 or the inlet baffle 103. The driving device may include, for example, a motor, a hydraulic device, or a transmission device to achieve the opening and closing of the permeable barrier 106 and / or the inlet baffle 103. Those skilled in the art can select the driving device according to actual needs, as long as it can achieve the technical principles of this application. This application does not specifically limit the specific implementation of the driving device in this embodiment.

[0054] In one embodiment, the driving device can drive both the inlet baffle 103 and the permeable blocking member 106 separately, thereby achieving separate control of the inlet baffle 103 and the permeable blocking member 106. For example, the driving device can drive both the permeable blocking member 106 and the inlet baffle 103 to open (e.g., both open simultaneously or sequentially), or it can drive both the permeable blocking member 106 and the inlet baffle 103 to close (e.g., both close simultaneously or sequentially), or it can drive the permeable blocking member 106 to close and the inlet baffle 103 to open.

[0055] The driving method described above for the driving device to drive the permeable barrier 106 and the inlet baffle 103 is merely exemplary and is not intended to limit the driving method of the driving device to drive the permeable barrier 106 and the inlet baffle 103. Those skilled in the art can selectively set the driving method to control the permeable barrier 106 and the inlet baffle 103 according to actual needs, as long as the technical principle of this application can be achieved.

[0056] In one embodiment, the inlet baffle 103 can be opened by the water flow into the water inlet.

[0057] For example, the inlet baffle 103 can be inwardly opening, that is, the inlet baffle 103 can be opened at the water inlet towards the inside of the automatic pool cleaning device. In this configuration, after the automatic pool cleaning device is filled with water, the inlet baffle 103 can be opened by the water flow at the water inlet (i.e., inwardly opening) without the need for a drive device to open the inlet baffle 103, thereby saving the power of the automatic pool cleaning device.

[0058] In one embodiment, the device further includes a control unit, wherein the control unit is capable of receiving a detection signal from the water inlet detection unit and controlling the automatic water tank cleaning device to enter the cleaning mode or the sinking and venting mode based on the detection signal.

[0059] Specifically, the automatic pool cleaning device may further include a control unit. This control unit can receive a detection signal from the water ingress detection unit, and upon detecting water entering the automatic pool cleaning device via the detection signal, can control the automatic pool cleaning device to enter either a surface cleaning mode or a submerged air venting mode. For example, the control unit can also control the automatic pool cleaning device to first enter the surface cleaning mode, and after the automatic pool cleaning device has operated in the surface cleaning mode for a preset time, then control the automatic pool cleaning device to enter the submerged air venting mode.

[0060] It is understood that the control unit can also be connected to the drive device, and thus the control unit can control the opening and closing of the water-permeable barrier 106 and / or the inlet baffle 103 by controlling the operation of the drive device.

[0061] In one embodiment, the device further includes a bottom-contact detection unit, which is capable of detecting whether the automatic pool cleaning device has sunk to the bottom of the pool. If the bottom-contact detection unit detects that the automatic pool cleaning device has sunk to the bottom of the pool, the bottom-contact detection unit triggers the automatic pool cleaning device to enter the bottom cleaning mode.

[0062] Specifically, the automatic pool cleaning device may also include a bottom contact detection unit, which can detect whether the automatic pool cleaning device has sunk to the bottom of the pool. When the bottom contact detection unit detects that the automatic pool cleaning device has sunk to the bottom of the pool, the bottom contact detection unit can trigger the automatic pool cleaning device to enter the bottom cleaning mode. For example, the bottom contact detection unit can send a detection signal to the control unit to inform the control unit that the automatic pool cleaning device has sunk to the bottom of the pool, and the control unit can control the automatic pool cleaning device to enter the bottom cleaning mode.

[0063] In one embodiment, the water-permeable barrier 106 is disposed on the inner or outer side of the inlet baffle 103.

[0064] Specifically, the permeable barrier 106 can be disposed on the inner or outer side of the inlet baffle 103. For example, when the permeable barrier 106 is disposed on the inner side of the inlet baffle 103, in one case, both the permeable barrier 106 and the inlet baffle 103 can be outwardly open, meaning they open at the water inlet towards the direction away from the automatic cleaning device of the pool; in another case, the permeable barrier 106 is inwardly open, and the inlet baffle 103 is outwardly open. When the permeable barrier 106 is disposed on the outer side of the inlet baffle 103, in one case, both the permeable barrier 106 and the inlet baffle 103 can be inwardly open; in another case, the permeable barrier 106 is outwardly open, and the inlet baffle 103 is inwardly open.

[0065] According to a second aspect of this application, a method for controlling the venting of an automatic water tank cleaning device during water immersion and submersion is provided. The control method 300 will be described in detail below with reference to the accompanying drawings.

[0066] Figure 3 This is a flowchart illustrating the air venting control method for the automatic water tank cleaning device provided in this application during water immersion and submersion. (For example...) Figure 3 As shown, the control method 300 includes steps 301 to 302. Steps 301 to 302 will be described in detail below.

[0067] In step 301, the automatic water tank cleaning device described above is controlled to enter the sinking and venting mode when it sinks.

[0068] Specifically, when the automatic cleaning device for the water tank sinks, it enters the sinking and venting mode. In the sinking and venting mode, the automatic cleaning device for the water tank needs to sink in the water tank and vent the gas inside the device during the sinking process.

[0069] In step 302, under the sinking and venting mode, the inlet baffle 103 is opened.

[0070] When the automatic water tank cleaning device needs to sink in the water tank and expel the gas inside the device during the sinking process, the inlet baffle 103 at the area where the water inlet of the automatic water tank cleaning device is located is opened so that the gas inside the automatic water tank cleaning device can be quickly discharged.

[0071] The above embodiments have the following beneficial effects:

[0072] Opening the inlet baffle 103 during the sinking process of the automatic water cleaning device can facilitate the rapid discharge of gas inside the device during the sinking process, thereby increasing the sinking speed of the automatic water cleaning device.

[0073] In one embodiment, when a water-permeable barrier 106 is provided at the area where the water inlet of the automatic water cleaning device is located, the water-permeable barrier 106 needs to be closed at the same time as the water inlet baffle 103 is opened, so as to prevent the garbage inside the automatic water cleaning device from overflowing into the water pool and causing the water quality in the water pool to be polluted again.

[0074] In one embodiment, the exhaust control method further includes: determining whether the automatic water tank cleaning device has sunk to the bottom of the water tank; if the automatic water tank cleaning device has sunk to the bottom of the water tank, controlling the automatic water tank cleaning device to enter the bottom cleaning mode; in the bottom cleaning mode, the inlet baffle 103 is closed, and water suction is performed through the bottom inlet of the automatic water tank cleaning device.

[0075] Specifically, during the process of the automatic cleaning device sinking in the pool, the sinking status of the automatic cleaning device can be detected in real time to determine whether the automatic cleaning device has sunk to the bottom of the pool. When the automatic cleaning device has sunk to the bottom of the pool, it means that the automatic cleaning device can start cleaning the bottom of the pool. At this time, the automatic cleaning device can be controlled to enter the bottom cleaning mode. In the bottom cleaning mode, the inlet baffle 103 at the water surface inlet can be closed, and water suction can be performed through the bottom inlet of the automatic cleaning device to clean the bottom of the pool.

[0076] Understandably, if the water pump power of the automatic pool cleaning device is large enough, the inlet baffle 103 and the bottom inlet can be opened simultaneously in the pool bottom cleaning mode. Water is drawn in through the bottom inlet to clean the bottom of the pool, and water is drawn in through the surface inlet to clean the water in the pool while cleaning the bottom. In this case, the cleaning efficiency is higher.

[0077] According to a third aspect of this application, a computer storage medium is provided, wherein a computer program is stored in the storage medium, and when the computer program is executed by a processor, it implements an exhaust control method for the automatic water tank cleaning device described in any of the above embodiments when it sinks into water, the control method comprising: controlling the automatic water tank cleaning device described in any of the above embodiments to enter a sinking exhaust mode when it sinks, and opening the water inlet baffle 103 in the sinking exhaust mode.

[0078] Fourthly, this application also provides a computer program product, which includes a computer program that can be stored on a non-transitory computer-readable storage medium. When the computer program is executed by a processor, the computer can execute the venting control method for the automatic water cleaning device of the pool when it sinks into the water provided by the above methods. The control method includes: controlling the automatic water cleaning device of the pool described in any of the above embodiments to enter the sinking venting mode when it sinks, and opening the water inlet baffle 103 in the sinking venting mode.

[0079] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units.
