Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of robots, in particular to a pool cleaning robot. BACKGROUND

[0002] The pool cleaning robot is a robot capable of performing cleaning tasks in a pool. Generally, a filter system is arranged in the body of the pool cleaning robot, and the filter system includes a dirt containing space and a filter assembly arranged therein. When the pool cleaning robot is working, external water can enter the body and flow through the dirt containing space, and the water filtered by the filter assembly is discharged from the body, while the dirt is left in the dirt containing space.

[0003] During the operation of the pool cleaning robot, when the dirt accumulates in the dirt containing space, the cleaning ability of the pool cleaning robot will decrease. At this time, the pool cleaning robot needs to be cleaned to restore its cleaning ability. However, frequent cleaning of the pool cleaning robot will result in low cleaning efficiency and increase the burden on the user. UTILITY MODEL CONTENT

[0004] The present application provides a pool cleaning robot, which aims to maintain good cleaning ability of the pool cleaning robot while reducing the frequency of cleaning the pool cleaning robot.

[0005] The specific technical solutions are as follows:

[0006] The present application provides a pool cleaning robot, which aims to maintain good cleaning ability of the pool cleaning robot while reducing the frequency of cleaning the pool cleaning robot.

[0007] The body;

[0008] The filter system is located in the interior of the body, and the filter system includes a dirt containing space I, a dirt containing space II, a filter assembly I and a filter assembly II. The filter assembly I is communicated with the dirt containing space I, and the filter assembly II is communicated with the dirt containing space II.

[0009] The water flow driving assembly is located in the interior of the body.

[0010] The water flow driving assembly has a first mode and a second mode.

[0011] When the water flow driving assembly is in the first mode, the water flow passes through the dirt containing space I, and the dirt in the water flow is collected in the dirt containing space I after being filtered by the filter assembly I.

[0012] In a case where the water flow driving assembly is in the second mode, water flows from the dirty space I to the dirty space II, and is filtered by the filter assembly II and discharged from the machine body; wherein the dirt in the dirty space I is collected in the dirty space II along with the water flow.

[0013] The pool cleaning robot in the embodiments of the present application can transfer the dirt in the dirty space I to the dirty space II when the water flow driving assembly is in the second mode, so that the pool cleaning robot can maintain good cleaning ability. Compared with the related art which only provides one dirty space, the frequency of cleaning the pool cleaning robot can be reduced, so that the cleaning efficiency of the pool cleaning robot can be improved, and the burden of the user can be reduced.

[0014] In some embodiments, the machine body is provided with a water inlet, a first water outlet and a second water outlet.

[0015] In a case where the water flow driving assembly is in the first mode, water flows into the dirty space I through the water inlet and is discharged through the first water outlet.

[0016] In a case where the water flow driving assembly is in the second mode, water flows into the dirty space I through the first water outlet, and is discharged through the second water outlet after passing through the dirty space II.

[0017] The machine body is provided with a water inlet and two water outlets. In a case where the water flow driving assembly is in the first mode, external water flows into the machine body through the water inlet, flows through the dirty space I, and is finally discharged through the first water outlet. In a case where the water flow driving assembly is in the second mode, external water flows into the machine body through the first water outlet, flows through the dirty space I and the dirty space II in turn, and is finally discharged through the second water outlet. As can be seen, by providing a water inlet and two water outlets, the water flow direction can be adapted to different working modes.

[0018] In some embodiments, the water flow driving assembly is located on the side of the dirty space I away from the dirty space II.

[0019] In this way, in the second mode, the water flow can be easily pushed from the dirty space I to the dirty space II when the driving assembly is working. This arrangement is beneficial to shorten the water flow path in the machine body, so that the energy loss of the water flow during the flow process can be reduced.

[0020] In some embodiments, the first water outlet, the water flow driving assembly and the dirty space I have a closed flow channel therebetween.

[0021] In this way, when the pool cleaning robot is in the first mode, the water flow driving assembly can efficiently drive the water flow through the dirty water storage space I and out through the first water outlet.

[0022] In some embodiments, the water flow driving assembly comprises an impeller and a motor connected to the impeller, and the rotation direction of the motor in the first mode is opposite to the rotation direction of the motor in the second mode.

[0023] When the water flow driving assembly is in the first mode, the motor drives the impeller to rotate forward, and under the driving action of the impeller, external water can directly enter the dirty water storage space I through the water inlet and flow in the direction of the impeller, and finally be discharged out of the machine body through the first water outlet. When the water flow driving assembly is switched from the first mode to the second mode, the motor drives the impeller to rotate reversely, and under the driving action of the impeller, external water enters the machine body from the first water outlet, and then flows through the dirty water storage space I and the dirty water storage space II in sequence, and is discharged out of the machine body through the second water outlet.

[0024] In some embodiments, the water inlet is provided with a one-way valve;

[0025] When the water flow driving assembly is in the first mode, the one-way valve is opened;

[0026] When the water flow driving assembly is in the second mode, the one-way valve is closed.

[0027] In this way, when the water flow driving assembly is in the second mode, it can be ensured that the water in the dirty water storage space I will not flow out of the machine body through the water inlet, thereby ensuring that the water flow smoothly enters the dirty water storage space II from the dirty water storage space I.

[0028] In some embodiments, a water flow channel is provided between the dirty water storage space I and the dirty water storage space II;

[0029] When the water flow driving assembly is in the first mode, the water flow channel is closed;

[0030] When the water flow driving assembly is in the second mode, the water flow channel is open.

[0031] In this way, when the water flow driving assembly is in the first mode, it is ensured that the water flow entering the machine body only passes through the dirty water storage space I and does not enter the dirty water storage space II, which is beneficial to avoid a part of the water flow entering and exiting the dirty water storage space II, thereby reducing the cleaning efficiency of the pool cleaning robot.

[0032] In some embodiments, the water flow passage communicates a lower portion of the dirty space I and the dirty space II when the water flow driving assembly is in the second mode.

[0033] In this way, dirt in the dirty space I can more easily enter the water flow passage and then enter the dirty space II through the water flow passage in the second mode.

[0034] In some embodiments, the water flow passage communicates a lowest portion of the dirty space I and the dirty space II when the water flow driving assembly is in the second mode.

[0035] In this way, dirt in the dirty space I can more easily enter the water flow passage and then enter the dirty space II through the water flow passage in the second mode.

[0036] In some embodiments, the filter assembly I includes a plurality of filter layers arranged in a stack, and the filter assembly II includes at least one filter layer.

[0037] The water flow driving assembly is in the first mode, which is the main working mode of the pool cleaning robot, that is, the pool cleaning robot is in the first mode most of the time when performing a cleaning task. In contrast, the second mode is mainly used to transfer dirt in the dirty space I and is only used when transferring dirt, that is, the pool cleaning robot is in the second mode only a small part of the time when performing a cleaning task. Based on the above, the number of filter layers included in the filter assembly I can be set to be more, for example, at least two layers, to ensure the filtering effect in the main working mode. The number of filter layers included in the filter assembly II can be one or more, as long as it can block dirt when transferring dirt and prevent dirt leakage.

[0038] In some embodiments, the filter layer is a porous material layer or a filter screen.

[0039] In some embodiments, the porous material includes a sponge.

[0040] In some embodiments, the filter system includes a mounting frame I and a mounting frame II, the dirty space I is formed inside the mounting frame I, and the dirty space II is formed inside the mounting frame II.

[0041] At least one of the mounting frame I and the mounting frame II is detachably connected to the body.

[0042] The dirty water accommodating space I is formed in the interior of the mounting frame I, which makes the mounting frame I and the filter assembly I located in the interior of the mounting frame I constitute an integral structure. Similarly, the dirty water accommodating space II is formed in the interior of the mounting frame II, which makes the mounting frame II and the filter assembly II located in the interior of the mounting frame II constitute an integral structure. In this way, when assembling, the integral structure constituted by the mounting frame I and the filter assembly I and the integral structure constituted by the mounting frame II and the filter assembly II can be connected with the body, which makes the assembling process more convenient. In addition, at least one of the mounting frame I and the mounting frame II is connected with the body in a detachable manner, which makes the mounting frame I and / or the mounting frame II can be separated from the body, so that the dirt in the dirty water accommodating space I and the dirty water accommodating space II can be cleaned.

[0056] The pool cleaning robot is a robot capable of performing cleaning tasks in a pool. Generally, a filter system is arranged in the body of the pool cleaning robot, which includes a dirt containing space and a filter assembly arranged therein. When the pool cleaning robot is working, external water can enter the body and flow through the dirt containing space, and the water filtered by the filter assembly is discharged from the body, while the dirt is left in the dirt containing space.

[0057] During the operation of the pool cleaning robot, when the dirt accumulates in the dirt containing space, the cleaning ability of the pool cleaning robot will decrease. At this time, the pool cleaning robot needs to be cleaned to restore its cleaning ability. However, frequent cleaning of the pool cleaning robot will result in low cleaning efficiency and also increase the burden on the user.

[0058] Based on the above situation, the embodiments of the present application provide a pool cleaning robot, which aims to maintain good cleaning ability of the pool cleaning robot while reducing the frequency of cleaning the pool cleaning robot.

[0059] AsFigure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown in the figure, this application embodiment provides a pool cleaning robot 10, which includes a body 100, a filtration system 200, and a water flow drive assembly 300. The filtration system 200 is located inside the body 100 and includes a dirt-containing space I 201, a dirt-containing space II 202, a filter assembly I, and a filter assembly II. Filter assembly I is connected to dirt-containing space I 201, and filter assembly II is connected to dirt-containing space II 202. The water flow drive assembly 300 is located inside the body 100. The water flow drive assembly 300 has a first mode and a second mode. When the water flow drive assembly 300 is in the first mode, the water flows through the dirt-containing space I 201 and is filtered by the filter assembly I, and the dirt in the water is collected in the dirt-containing space I 201. When the water flow drive assembly 300 is in the second mode, the water flows from the dirt collection space I 201 into the dirt collection space II 202, and is discharged from the body 100 after being filtered by the filter assembly II; wherein, the dirt in the dirt collection space I 201 is collected in the dirt collection space II 202 along with the water flow.

[0060] It is understood that filter assembly I is connected to the dirt-containing space I 201, both when filter assembly I is located within the dirt-containing space I 201 and when filter assembly I is arranged adjacent to the dirt-containing space I 201. Similarly, filter assembly II is connected to the dirt-containing space II 202, both when filter assembly II is located within the dirt-containing space II 202 and when filter assembly II is arranged adjacent to the dirt-containing space II 202.

[0061] The pool cleaning robot 10 in this embodiment includes a filtration system 200 comprising a dirt-containing space I 201 and a dirt-containing space II 202, and filter components I and II respectively connected to the dirt-containing spaces I 201 and II 202. When the water flow drive component 300 is in the first mode, under the action of the water flow drive component 300, external water enters the body 100, flows through the dirt-containing space I 201, is filtered by the filter component I, and is then discharged outside the body 100. During this process, the filtered dirt is stored in the dirt-containing space I 201.

[0062] When the dirt in the dirty water storage space 201 accumulates to a certain extent, the water flow driving assembly 300 can be switched to the second mode. At this time, under the action of the water flow driving assembly 300, the water flow enters the dirty water storage space 202 from the dirty water storage space 201 and is filtered by the filtering assembly II, and then is discharged out of the machine body 100. In the process of the water flow entering the dirty water storage space 202 from the dirty water storage space 201, the dirt in the dirty water storage space 201 is washed into the dirty water storage space 202 and is stored in the dirty water storage space 202.

[0063] As the dirt in the dirty water storage space 201 decreases, the cleaning ability of the pool cleaning robot 10 is restored, and then the pool cleaning robot 10 can be switched back to the first mode and continue to perform the cleaning work in the first mode.

[0064] The pool cleaning robot 10 in the embodiment of the present application can transfer the dirt in the dirty water storage space 201 to the dirty water storage space 202 when the water flow driving assembly 300 is in the second mode, so that the pool cleaning robot 10 maintains good cleaning ability. Compared with the related art which only provides one dirty water storage space, the frequency of cleaning the pool cleaning robot 10 can be reduced, thereby facilitating the improvement of the cleaning efficiency of the pool cleaning robot 10, and also reducing the burden on the user.

[0065] In some embodiments, the machine body 100 is provided with a water inlet 101, a first water outlet 102 and a second water outlet 103. When the water flow driving assembly 300 is in the first mode, the water flow enters the dirty water storage space 201 through the water inlet 101 and is discharged through the first water outlet 102. When the water flow driving assembly 300 is in the second mode, the water flow enters the dirty water storage space 201 through the first water outlet 102 and is discharged through the second water outlet 103 after passing through the dirty water storage space II 202.

[0066] The machine body 100 is provided with a water inlet 101 and two water outlets. When the water flow driving assembly 300 is in the first mode, the external water flow enters the machine body 100 through the water inlet 101 and flows through the dirty water storage space 201, and is finally discharged through the first water outlet 102. When the water flow driving assembly 300 is in the second mode, the external water flow enters the machine body 100 through the first water outlet 102 and flows through the dirty water storage space I 201 and the dirty water storage space II 202 in turn, and is finally discharged through the second water outlet 103. As can be seen, by providing the water inlet 101 and the two water outlets, the water flow direction in different working modes can be adapted.

[0067] In one embodiment, the water flow driving assembly 300 is located on the side of the dirt containing space 201 away from the dirt containing space 202.

[0068] The water flow driving assembly 300 is located on the side of the dirt containing space 201 away from the dirt containing space 202, that is, the dirt containing space 201 is located between the water flow driving assembly 300 and the dirt containing space 202. In this way, in the second mode, the water flow can be more easily pushed from the dirt containing space 201 to the dirt containing space 202 when the driving assembly is working. This arrangement is conducive to shortening the water flow path in the machine body 100, thereby reducing the energy loss of the water flow during the flow process.

[0069] In one embodiment, the first water outlet 102, the water flow driving assembly 300, and the dirt containing space 201 have a closed flow channel.

[0070] In this way, in the case where the pool cleaning robot 10 is in the first mode, the water flow driving assembly 300 can more efficiently make the water flow through the dirt containing space 201 and be discharged through the first water outlet 102.

[0071] Further, the water flow driving assembly 300 includes an impeller 301 and a motor 302 connected to the impeller 301, and the rotation direction of the motor 302 in the first mode is opposite to the rotation direction of the motor 302 in the second mode.

[0072] In the case where the water flow driving assembly 300 is in the first mode, the motor 302 drives the impeller 301 to rotate forward, and under the driving action of the impeller 301, external water can directly enter the dirt containing space 201 through the water inlet 101 and flow in the direction of the impeller 301, and finally be discharged to the outside of the machine body 100 through the first water outlet 102.

[0073] When the water flow driving assembly 300 is switched from the first mode to the second mode, the motor 302 drives the impeller 301 to rotate reversely, and under the driving action of the impeller 301, external water enters the machine body 100 through the first water outlet 102, and then flows through the dirt containing space 201 and the dirt containing space 202 in turn, and is discharged to the outside of the machine body 100 through the second water outlet 103.

[0074] In some embodiments, the water inlet 101 is provided with a one-way valve. In the case where the water flow driving assembly 300 is in the first mode, the one-way valve is opened; in the case where the water flow driving assembly 300 is in the second mode, the one-way valve is closed.

[0075] In this way, when the water flow driving assembly 300 is in the second mode, the water in the dirty water storage space 201 cannot flow out of the machine body 100 through the water inlet 101, so that the water flow can smoothly flow from the dirty water storage space 201 to the dirty water storage space 202.

[0076] In one embodiment, the one-way valve is the first baffle 104, which is arranged on the inner side of the machine body 100 and is hinged to the machine body 100. The first baffle 104 can cover the water inlet 101.

[0077] In this way, when the water flow driving assembly 300 is in the first mode, the pressure outside the first baffle 104 is greater than the pressure inside the first baffle 104. Under the action of the pressure difference, the first baffle 104 rotates inside the machine body 100, so that the water inlet 101 is in an open state. When the pool cleaning robot 10 is in the second mode, under the action of the water flow driving assembly 300, the pressure inside the first baffle 104 is greater than the pressure outside the first baffle 104. Under the action of the pressure difference, the first baffle 104 tightly abuts against the inner wall of the machine body 100 and covers the water inlet 101, so that the water inlet 101 is in a closed state.

[0078] In addition, the first baffle 104 is used as the one-way valve, which has a simple structure, is easy to process, and has a low cost.

[0079] In some embodiments, a water flow channel 205 is arranged between the dirty water storage space 201 and the dirty water storage space 202. When the water flow driving assembly 300 is in the first mode, the water flow channel 205 is closed; and when the water flow driving assembly 300 is in the second mode, the water flow channel 205 is open.

[0080] In this way, when the water flow driving assembly 300 is in the first mode, it is ensured that the water flow entering the machine body 100 only passes through the dirty water storage space 201 and does not enter the dirty water storage space 202, which is beneficial to avoid the water flow entering and exiting the dirty water storage space 202, thereby reducing the cleaning efficiency of the pool cleaning robot 10.

[0081] In some embodiments, when the water flow driving assembly 300 is in the second mode, the water flow channel 205 communicates the lower part of the dirty water storage space 201 and the dirty water storage space 202.

[0082] In this way, the dirt in the dirty water storage space 201 in the second mode can more easily enter the water flow channel 205, and then enter the dirty water storage space 202 through the water flow channel 205.

[0083] In one embodiment, the water flow passage 205 is in communication with the lowest part of the dirt containing space I 201 and the dirt containing space II 202 when the water flow driving assembly 300 is in the second mode.

[0084] Thus, in the second mode, dirt in the dirt containing space I 201 can more easily enter the water flow passage 205 and then enter the dirt containing space II 202 through the water flow passage 205.

[0085] In some embodiments, a partition is provided between the water flow passage 205 and the dirt containing space I 201, and an opening is provided on the partition, which is in communication with the dirt containing space I 201 and the water flow passage 205. A second baffle 206 is provided in the water flow passage 205, the top of the second baffle 206 is hinged to the partition, and the second baffle 206 can cover the opening.

[0086] The top of the second baffle 206 is hinged to the partition, and under the action of gravity, the second baffle 206 is in an upright state, thereby covering the opening on the partition. When the pool cleaning robot 10 is in the first mode, water flows in the dirt containing space I 201, which makes the water on both sides of the second baffle 206 have different flow rates. According to Bernoulli's equation, the water pressure on both sides of the second baffle 206 is also different, specifically, the water pressure on the side of the second baffle 206 facing the water flow passage 205 is greater than the water pressure on the side facing the dirt containing space I 201, so that a pressure difference is formed on both sides of the second baffle 206, and under the action of the pressure difference, the second baffle 206 tightly abuts against the partition, maintaining the covering state of the opening.

[0087] When the water flow driving assembly 300 is in the second mode, under the action of the water flow driving assembly 300, the water pressure in the dirt containing space I 201 is greater than the water pressure in the water flow passage 205, and under the action of the pressure difference, the second baffle 206 rotates to expose the opening, so that the water flow in the dirt containing space I 201 can enter the dirt containing space II 202 through the water flow passage 205.

[0088] In some embodiments, the filter assembly I includes a plurality of filter layers arranged in layers, and the filter assembly II includes at least one filter layer.

[0089] The water flow driving assembly 300 is in the first mode, which is the main working mode of the pool cleaning robot 10, that is, the water flow driving assembly 300 is in the first mode most of the time when the pool cleaning robot 10 performs a cleaning task. In contrast, the second mode is mainly used for transferring the dirt in the dirty space 201, and is only used when the dirt is transferred, that is, the water flow driving assembly 300 is in the second mode only for a small part of the time when the pool cleaning robot performs a cleaning task. Based on the above, the number of filter layers included in the filter assembly I can be set to be more, for example, at least two, to ensure the filtering effect in the main working mode. The number of filter layers included in the filter assembly II can be one or more, as long as it can block the dirt when the dirt is transferred and prevent the dirt from leaking.

[0090] Further, the filter layer is a porous material layer or a filter screen. When the number of filter layers is multiple, each filter layer can be a same structure layer or a different structure layer. For example, the filter assembly can be a combination structure of a porous material layer and a filter screen.

[0091] It can be understood that the size of the pores of the porous material is much smaller than the size of the mesh of the filter screen, and therefore, the filter screen can achieve relatively rough filtering, and the porous material layer can achieve relatively fine filtering.

[0092] Specifically, when the filter layer is a porous material layer, along the front-rear direction of the body 100, the water inlet 101 is located between the porous material layer of the filter assembly I and the porous material layer of the filter assembly II. In this way, in the first mode, the water flow entering the dirty space 201 through the water inlet 101 is blocked by the filter assembly I on the side close to the dirty space 202 during the filtering process of the filter assembly I. In this way, when the pool cleaning robot 10 switches to the second mode, the dirt is flushed into the dirty space 202 by the water flow and is blocked by the filter assembly II, thereby ensuring that the dirt is stored in the dirty space 202 and does not leak out of the body 100 through the second water outlet 103.

[0093] Specifically, the porous material includes a sponge, which has a good filtering effect and a low cost.

[0094] In some embodiments, the filter system 200 includes a mounting frame I 207 and a mounting frame II 208, the dirty space 201 is formed in the inside of the mounting frame I 207, and the dirty space 202 is formed in the inside of the mounting frame II 208. At least one of the mounting frame I 207 and the mounting frame II 208 is detachably connected with the body 100.

[0095] The dirty material accommodating space 201 is formed in the interior of the mounting frame 207, which makes the mounting frame 207 and the filter assembly I located in the interior of the mounting frame 207 form an integral structure. Similarly, the dirty material accommodating space 202 is formed in the interior of the mounting frame 208, which makes the mounting frame 208 and the filter assembly II located in the interior of the mounting frame 208 form an integral structure. In this way, in the assembly process, the integral structure formed by the mounting frame 207 and the filter assembly I and the integral structure formed by the mounting frame 208 and the filter assembly II can be connected with the body 100, which makes the assembly process more convenient.
