Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and particularly relates to a cleaning base station and cleaning equipment. Background Technology

[0002] A cleaning robot is a smart home appliance used for automatically cleaning floors. A cleaning base station can perform multiple interactive tasks on the cleaning robot, including charging, refilling water, washing, drying, and dust collection. The cleaning base station in related technologies includes a water tank and a washing chamber. The washing chamber has multiple spray nozzles to direct water flow from multiple locations. The water tank is pre-filled with water at a certain level and is connected to each spray nozzle to direct water flow, thereby enabling the cleaning robot to clean and / or rinse the washing chamber. However, the water tank is relatively large, occupying a significant amount of space, resulting in a large cleaning base station. Furthermore, when the water in the tank is depleted, the cleaning robot and / or washing chamber need to be in standby mode while waiting for refills, affecting the cleaning efficiency of the base station. Summary of the Invention

[0003] In view of this, the present invention provides a cleaning base station and cleaning equipment to solve the technical problem of how to improve cleaning efficiency while reducing the size of the cleaning base station.

[0004] The technical solution provided by the embodiments of the present invention is implemented as follows:

[0005] A cleaning base station includes: a cleaning chamber, which is hollow inside, for at least docking and cleaning a cleaning robot, and a spray nozzle for discharging water; and a water circuit board, including an inlet pipe, multiple outlet pipes, and a guide pipe connecting the inlet pipe and the outlet pipes, wherein the inlet pipe is used to introduce water, and the spray nozzles are connected to the outlet pipes to supply water to the cleaning chamber and / or rinse the cleaning chamber.

[0006] In some embodiments, the diversion pipeline includes: a first branch connected to the inlet pipeline; multiple second branches connected to each of the outlet pipelines; and a connecting pipeline, one end of which is connected to the inlet pipeline and / or the first branch, and the other end of which is connected to each of the second branches, so that the water flow from the inlet pipeline is diverted to the corresponding outlet pipeline via each of the second branches.

[0007] In some embodiments, the connecting pipeline includes a manifold and a plurality of spaced-apart branch pipes. One end of the manifold is connected to the inlet pipe and / or the first branch, and each branch pipe is connected to the other end and / or the same side of the manifold. The number of the second branches is greater than the number of the branch pipes.

[0008] In some embodiments, two water distribution pipes are provided, and each water distribution pipe is connected to two second branches.

[0009] In some embodiments, along the direction of water flow from the inlet pipe toward the manifold, the cross-sectional area of ​​the outlet pipe closer to the inlet pipe is larger than the cross-sectional area of ​​the outlet pipe farther from the inlet pipe.

[0010] In some embodiments, each of the water distribution pipes is connected to an equal number of water outlet pipes, and there are two or more of them; each of the spray nozzles is arranged in groups, and the number of each group is equal to the total number of the water distribution pipes; wherein, at least two groups of spray nozzles are arranged opposite each other in the cleaning chamber, and each of the water outlet pipes on each of the water distribution pipes is connected to one of the spray nozzles in each group.

[0011] In some embodiments, the cleaning base station further includes a liquid pump for pumping out wastewater from the cleaning chamber; wherein the water circuit board further includes a flushing pipe connected to at least the water inlet pipe, the flushing pipe being used to direct water flow to the liquid pump.

[0012] In some embodiments, the flow guide pipe further includes a third branch, through which the flushing pipe is connected to the water inlet pipe or to the first branch; wherein the cross-sectional area of ​​the flow channel of the third branch is smaller than the cross-sectional area of ​​the flow channel of the manifold.

[0013] In some embodiments, the water channel plate includes an upper cover and a lower cover, which are fixedly connected and together form the flow guide pipe.

[0014] In some embodiments, the lower cover is configured as the top cover of the cleaning chamber.

[0015] This invention provides a cleaning device, including the aforementioned cleaning base station and a clothing processing device for cleaning clothing; the cleaning base station is disposed at the bottom of the clothing processing device, and the water circuit board in the cleaning base station is connected to the water inlet valve of the clothing processing device.

[0016] This invention provides a cleaning base station and cleaning equipment. The cleaning base station includes a cleaning chamber and a water circuit board. The cleaning chamber is hollow and serves at least as a docking point for cleaning robots. The cleaning chamber is equipped with spray nozzles for discharging water. The water circuit board includes an inlet pipe, multiple outlet pipes, and a guide pipe. The inlet pipe introduces water from the outlet components. The guide pipes connect the inlet and outlet pipes to direct the water flow from the inlet pipes to the outlet pipes. The spray nozzles are connected to the outlet pipes to supply water to the cleaning chamber and / or rinse the cleaning chamber. This design allows the water circuit board to directly connect to the outlet components and guide and divert the water flow, reducing the need for additional water circuit components for flow guidance and diversion. Furthermore, the water circuit board does not require a pre-existing water storage cavity, resulting in a smaller volume and thus a smaller overall size for the cleaning base station. Simultaneously, the cleaning robot and / or cleaning chamber do not need to wait for water replenishment and can be supplied with water at any time, improving the cleaning efficiency of the cleaning base station.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0028] In the following description, the terms "first," "second," "etc." are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions under normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use.

[0029] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0030] This invention provides a cleaning base station and a cleaning device, wherein the cleaning device includes at least a cleaning base station. Figure 1 and Figure 2As shown, the cleaning base station includes a cleaning chamber 1 and a water channel plate 2. The cleaning chamber 1 is hollow and is used at least for docking and cleaning cleaning robots, including but not limited to sweeping and mopping robots, floor mopping robots, sweeping and mopping combos, or floor scrubbers. The water channel plate 2 directs water flow to the cleaning chamber 1. The cleaning chamber 1 is equipped with spray nozzles 11 for discharging water, so as to supply water to the cleaning chamber 1 and / or rinse the cleaning chamber 1 through the spray nozzles 11. For example, after the water flow from the spray nozzles 11 is supplied to the cleaning tank 12 of the cleaning chamber 1, the brush 13 inside the cleaning chamber 1 can clean the mop of the cleaning robot and / or clean the outer shell of the cleaning robot. After the cleaning chamber 1 completes the cleaning operation on the cleaning robot, that is, after the cleaning robot leaves the cleaning chamber 1, the water flow from the spray nozzles 11 can rinse away any remaining debris in the cleaning chamber 1. The waste remaining in the cleaning chamber 1 can be solids such as dust and impurities, or liquids such as wastewater from the cleaning robot, depending on the type of cleaning robot and the working environment. The water flow discharged from the spray nozzle 11 can be domestic wastewater containing a small amount of waste, clean water, or washing water containing detergent, depending on the water flow introduced by the water circuit board 2. This water circuit board 2 can adapt to various types of water flow and does not have high requirements for the cleanliness of the water flow itself, thus increasing the scope of application of the water circuit board 2. It should be noted that the application scenario type of this embodiment does not limit the structure of the cleaning base station and cleaning equipment of this embodiment.

[0031] Reference Figure 3 and Figure 4 The water circuit board 2 includes an inlet pipe 21, an outlet pipe 22, and a guide pipe 23. Multiple outlet pipes 22 are provided. The guide pipes 23 connect the inlet pipes 21 to each outlet pipe 22. The inlet pipes 21 guide the water flow from the outlet components into the guide pipes 23. The guide pipes 23 direct the water flow to each outlet pipe 22. Each outlet pipe 22 is connected to a spray nozzle, such as... Figure 1 As shown, water is supplied to and / or the cleaning chamber 1 is rinsed via spray nozzle 11, that is, referring to Figure 1 The cleaning chamber 1 is provided with multiple spray nozzles 11 to supply water to the cleaning tank 12 inside the cleaning chamber 1 at multiple locations. When the cleaning tank 12 has multiple brush plates 13, each spray nozzle 11 can simultaneously wet and / or rinse each brush plate 13 at multiple locations, and can supply water to and / or rinse the cleaning tank 12 together at multiple locations.

[0032] It should be noted that the water outlet component can be a faucet, a water pipe, a valve body connected to the faucet and / or water pipe, or a water outlet component of other devices, such as a component on a water heater or laundry detergent unit 3 that introduces and / or exits water flow. Regardless of the structure of the water outlet component or the device it is connected to, the inlet pipe 21 can introduce water flow into the water outlet component, and then the guide pipe 23 directs the water flow to each outlet pipe 22. (Refer to...) Figures 1 to 4 In this embodiment of the invention, the water channel plate 2 directly directs the water flow to the spray nozzle 11 without pre-storing a certain water level. The water channel plate 2 does not require a cavity for water storage, thus allowing it to direct the water flow to the spray nozzle 11 with a smaller volume. The smaller size of the water channel plate 2 avoids occupying a large space, which helps reduce the size of the cleaning base station. Furthermore, unlike a water tank, the water channel plate 2 does not require automatic or manual water replenishment. The spray nozzle 11 can directly discharge water to clean the cleaning robot and / or rinse the cleaning chamber 1, thereby improving the cleaning efficiency of the cleaning base station.

[0033] Understandably, referring to Figure 1 and Figure 4 In the aforementioned context, "multiple water outlet pipes 22" indicates that the number of water outlet pipes 22 is two or more; "water outlet pipes 22 are connected to spray nozzles 11 one by one" indicates that one water outlet pipe 22 is connected to one spray nozzle 11. The spray nozzle 11 can be a through hole opened in the inner wall of the cleaning chamber 1, or it can be an internal pipe of the spray head; the water outlet end of the water outlet pipe 22 can be directly connected to the location of the spray nozzle 11, thus directly connecting to the spray nozzle 11; of course, the water outlet pipe 22 can also be as follows... Figure 1 The spray nozzle 11 is indirectly connected via a water pipe. This application does not limit the specific structure of the spray nozzle 11, nor does it limit the specific connection structure between the water outlet pipe 22 and the spray nozzle 11, as long as the water flow at each water outlet pipe 22 can be directed to the cleaning chamber 1 through the spray nozzle 11. However, regardless of how the water outlet pipe 22 is set, the number of water outlet pipes 22 in the water circuit board 2 is greater than the number of water inlet pipes 21. The water circuit board 2 achieves the effect of guiding and diverting the flow, eliminating the need to install adapters, valves, and other water circuit accessories in the cleaning base station to achieve guiding and diverting the flow, reducing the assembly difficulty of water circuit accessories in the cleaning base station, and making the water pipe laying in the cleaning base station simpler.

[0034] This invention provides a cleaning base station, which includes a cleaning chamber 1 and a water circuit board 2. The cleaning chamber 1 is hollow and is used at least for docking and cleaning cleaning robots. The cleaning chamber 1 is equipped with spray nozzles 11 for discharging water. The water circuit board 2 includes an inlet pipe 21, multiple outlet pipes 22, and a guide pipe 23. The inlet pipe 21 is used to introduce water flow from the outlet pipes. The guide pipes 23 connect the inlet pipe 21 and the outlet pipes 22 to guide the water flow introduced by the inlet pipe 21 to each outlet pipe 22. The spray nozzles 11 are connected to the outlet pipes 22 one by one to supply water to the cleaning chamber 1 and / or rinse the cleaning chamber 1. This application utilizes a water circuit board 2 to directly guide and divert water flow from the outlet components. This eliminates the need for adapters, valves, or other water circuit accessories within the cleaning base station for this purpose. Furthermore, the water circuit board 2 does not require a pre-existing water storage cavity. Unlike a water tank, the water circuit board 2 does not require automatic or manual water replenishment. Moreover, the smaller size of the water circuit board 2 and the reduced number of water circuit accessories within the cleaning base station contribute to its compact size. With the water circuit board 2 installed, the cleaning robot and / or cleaning chamber 1 do not need to wait for water replenishment, resulting in higher cleaning efficiency at the cleaning base station.

[0035] In some embodiments, reference is made to Figure 1 and Figure 2 The cleaning base station is adjacent to the clothing handling device 3 to enable the water circuit board 2 to communicate with the components of the clothing handling device 3 that introduce and / or discharge water flow, but at least to the components that introduce water flow in the clothing handling device 3. That is, the water circuit board 2 can at least introduce water flow from the inlet valve 31 of the clothing handling device 3. In other words, the outlet component can be the inlet valve 31 of the clothing handling device 3, or the inlet valve 31 of the clothing handling device 3 and the drain valve for discharging water flow (not shown in the figure). To facilitate understanding, let's take the example of the water inlet valve 31 and the drain valve of the clothing processing device 3 connected to the water circuit board 2: The drain valve can be equipped with a start-up program. Suppose that the clothing processing device 3 is to dehydrate three times. After the first and second dehydration, the drain valve is not connected to the water circuit board 2. The water circuit board 2 introduces water flow from the water inlet valve 31 of the clothing processing device 3. The cleaning base station can start the cleaning operation without waiting for the clothing processing device 3 to discharge wastewater. After the third dehydration, the drain valve is connected to the water circuit board 2. The water circuit board 2 can introduce washing wastewater that does not contain impurities or contains a small amount of impurities to rinse the cleaning chamber 1 and / or supply water to the cleaning chamber 1, making reasonable use of wastewater and saving water resources.

[0036] In some possible embodiments, refer to Figure 1 and Figure 2The water outlet is the inlet valve 31 of the clothing handling device. The inlet pipe 21 is connected to the inlet valve 31 to supply clean water to the water circuit board 2. The water circuit board 2 and the clothing handling device 3 share the same inlet valve 31, further reducing the number of water circuit components in the cleaning base station. The connection between the water circuit board 2 and the inlet valve 31 allows for direct supply of clean water, reducing the possibility of detergents such as laundry powder and liquid being introduced into the cleaning chamber 1 through the washing wastewater and remaining on the cleaning robot's mop, thereby reducing the likelihood of slippery or uneven surfaces after the cleaning robot has mopped. In some possible implementations, a flow meter can also be installed at the connection point between the inlet valve 31 and the inlet pipe 21 to monitor the inflow status of clean water and the flow rate of clean water supplied by the inlet pipe 21.

[0037] In some embodiments, reference is made to Figure 4 The diversion pipe 23 includes a first branch 231, a second branch 232, and a connecting pipe 233. The first branch 231 is connected to the inlet pipe 21; the second branch 232 has multiple branches, each connected to an outlet pipe 22. Figure 4 In the schematic diagram shown, all the branch paths within the elliptical frame are second branch paths 232. (Refer to...) Figure 5 The second branch 232 is defined as 232a, 232b, 232c, and so on up to 232n. The outlet pipes 22 are defined as 22a, 22b, 22c, and so on up to 22n. Then 232a is connected to 22a, 232b is connected to 22b, and so on up to 232n. One end of the connecting pipe 233 is connected to the inlet pipe 21 and / or the first branch 231 to supply water flowing through the inlet pipe 21. It can be understood that one end (left end) of the connecting pipe 233 can be directly connected to the inlet pipe 21, or, as shown in the schematic diagram of this application, indirectly connected to the inlet pipe 21 by connecting to the first branch 231. In this embodiment, it can be considered that one end (left end) of the connecting pipe 233 is connected to both the inlet pipe 21 and the first branch 231. The other end (right end) of the connecting pipe 233 is connected to each of the second branches 232, so that the water flow from the inlet pipe 21 is guided to the corresponding outlet pipe 22 through each of the second branches 232. That is, before the water flows out of the outlet pipe 22, the second branches 232 have already diverted the water flow from the connecting pipe 233. Therefore, even if the locations of the outlet pipes 22 are different, each outlet pipe 22 can still guide the water flow, thus allowing the spray nozzles 11 to function as described above. Figure 1 As shown, water is discharged from multiple locations to wet and / or rinse each brush plate 13.

[0038] In some embodiments, refer to Figure 6The water channel plate 2 includes an upper cover 201 and a lower cover 202. The upper cover 201 and the lower cover 202 are fixedly connected and together form a flow guide pipe, reducing the processing and forming difficulty of the flow guide pipe. It is understood that this is for illustrative purposes only. Figure 4 The upper cover 201 is omitted. The upper cover 201 and the lower cover 202 can be detachably connected by means of snap-fit, interlocking of connectors (screws, bolts, etc.), or they can be permanently fixed by means of welding, riveting, etc. In some possible implementations, the upper cover 201 and the lower cover 202 are welded to each other to reduce the difficulty of setting up a sealing structure for the upper cover 201 and the lower cover 202.

[0039] In some embodiments, refer to Figure 1 , Figure 2 and Figure 6 The top cover 14 of the cleaning chamber 1 can be set as the bottom cover 202, meaning that the flow channels inside the water circuit board 2 can be formed on the top cover 14. This design reduces the assembly process of the bottom cover 202, thereby simplifying the assembly difficulty of the cleaning chamber 1 and the water circuit board 2. Furthermore, the overall height of the assembled cleaning chamber 1 and the water circuit board 2 does not need to be calculated based on the height of the bottom cover 202, but only on the height of the top cover 201 and the top cover 14. This helps to reduce the overall height of the cleaning base station, thereby further reducing the volume of the cleaning base station.

[0040] In some embodiments, refer to Figure 5 The connecting pipe 233 includes a manifold 2331 and a plurality of spaced-apart branch pipes 2332. One end (left end) of the manifold 2331 is connected to the inlet pipe 21 and / or the first branch 231. That is, the manifold 2331 is the component in the connecting pipe 233 that supplies water flowing from the inlet pipe 21. It can be understood that one end (left end) of the manifold 2331 can be directly connected to the inlet pipe 21, or it can be indirectly connected to the inlet pipe 21 by being connected to the first branch 231 as shown in the schematic diagram of this application. In this embodiment, it can be regarded as one end (left end) of the manifold 2331 being connected to both the inlet pipe 21 and the first branch 231.

[0041] Reference Figure 5Each branch pipe 2332 is connected to the other end and / or the same side of the manifold 2331 so that the water flow from the manifold 2331 is directed through each branch pipe 2332 to the corresponding outlet pipe 22. Each branch pipe 2332 is connected to the other end (right end) of the manifold 2331 away from the inlet pipe 21; or, each branch pipe 2332 is connected to the same side (upper or lower) of the manifold 2331; or, some branch pipes in each branch pipe 2332 are connected to the other end (right end) of the manifold 2331, and other branch pipes in each branch pipe 2332 are connected to the same side (upper or lower) of the manifold 2331. For example, one branch pipe 2332 is connected to the right end of the manifold 2331, and another branch pipe 2332 is connected to the lower side of the manifold 2331. It should be noted that if some branch pipes 2332 are connected to both sides of the manifold 2331, they can also be considered as connected to the other end of the manifold 2331. This application does not limit the specific location of each water distribution pipe 2332 within the manifold 2331, as long as the water flow within the manifold 2331 can be guided to each outlet pipe 22 via each water distribution pipe 2332. Each water distribution pipe 2332 is connected to the other end and / or the same side of the manifold 2331, allowing each outlet pipe 22 to be arranged adjacently, reducing the difficulty of laying water pipes connected to each outlet pipe 22. Furthermore, all laid water pipes are connected to the same end and / or the same side of the water circuit board 2, making the water pipe laying process simpler. In addition, the arrangement of each water distribution pipe 2332 does not occupy the thickness space of the water circuit board 2, but still utilizes the length and / or width space of the water circuit board 2 for layout, further reducing the volume of the cleaning base station.

[0042] In the embodiments shown in this application, reference is made to Figure 5The schematic diagram of water flow direction shows that the water flow direction in the water circuit board 2 flows sequentially through: inlet pipe 21, first branch 231, confluence pipe 2331, each branch pipe 2332, each second branch 232, and each outlet pipe 22. Among them, the number of second branch lines 232 is greater than the number of water distribution pipes 2332. For ease of explanation, it is assumed that there are three second branch lines 232, namely 232a, 232b, and 232c. Correspondingly, there are also three outlet pipes 22, namely 22a, 22b, and 22c. There are multiple water distribution pipes 2332, and the number of water distribution pipes 2332 is less than the number of second branch lines 232. Therefore, there are two water distribution pipes 2332, namely 2332a and 2332b. 2332a can connect to two of the three first branch lines 231, or 2332b can connect to two of the three first branch lines 231. The water distribution pipes 2332 divide the water flowing from the confluence pipes 2331 into two streams, and each second branch line 232 divides the second branch line 232 into three streams. This application does not limit the specific number of water distribution pipes 2332 and second branch lines 232, as long as the number of second branch lines 232 is greater than the number of water distribution pipes 2332. This arrangement ensures that before the water flow is divided into a larger quantity at the second branch lines 232, it is first divided into a smaller quantity by the water distribution pipes 2332. The water distribution pipes 2332 then transfer the smaller quantity of water to the second branch lines 232, allowing each second branch line 232 to smoothly discharge water.

[0043] In some possible embodiments, refer to Figure 5 This design allows the cross-sectional area of ​​the manifold 2331 to be larger than that of the branch pipe 2332, and the cross-sectional area of ​​the branch pipe 2332 to be larger than that of the second branch 232. From the manifold 2331 to each branch pipe 2332, and then to each second branch 232, the cross-sectional area decreases. According to Bernoulli's principle, the water velocity increases from the manifold 2331 to each branch pipe 2332 and then to each second branch 232. This facilitates the smooth flow of water through each outlet pipe 22 and also allows the water circuit board 2 to quickly discharge water, enabling the cleaning base station to begin cleaning operations quickly. It is understood that "cross-sectional area" refers to the cross-sectional area within the pipe in the direction perpendicular to the water flow direction.

[0044] In some possible embodiments, refer to Figure 5The number of second branches 232 can be set to an even number and evenly divided into groups. Each branch pipe 2332 is connected to a group of second branches 232, and the number of second branches 232 connected to each branch pipe 2332 is equal, so that the water flow rate from each second branch 232 is more uniform, thereby making the water flow rate from each spray nozzle 11 more uniform. This allows each spray nozzle 11 to uniformly supply water to and / or rinse the cleaning chamber 1 at multiple locations. In the schematic diagram shown in this application, refer to... Figure 5 There are two water distribution pipes 2332, and each water distribution pipe 2332 is connected to two second branches 232. That is, there are four second branches 232 (232a, 232b, 232c, 232d). Correspondingly, there are also four outlet pipes 22 (22a, 22b, 22c, 22d). The two water distribution pipes 2332 are defined as 2332a and 2332b. The two second branches 232 are in a group, that is, 2332a is connected to 232a and 232b, and 2332b is connected to 232c and 232d. This configuration ensures that each branch in each water circuit board 2 that requires diversion will split the water flow into two streams. For example, the branch pipe 2332 connects to the branch of two second branch 232, and the confluence pipe 2331 connects to the branch of two branch pipes 2332. This not only allows for gradual diversion but also makes the structure of each branch in the water circuit board 2 that achieves diversion relatively similar, which is convenient for the processing and manufacturing of the water circuit board 2.

[0045] In some embodiments, refer to Figure 5 The water flows in the direction from the inlet pipe 21 toward the manifold pipe 2331, i.e. Figure 5From left to right, the cross-sectional area of ​​the outlet pipe 22 closer to the inlet pipe 21 is larger than that of the outlet pipe 22 farther from the inlet pipe 21. For ease of explanation, referring to the above embodiment, the outlet pipe 22 closest to the inlet pipe 21 (the leftmost outlet pipe) is defined as 22a, and the outlet pipe 22 farthest from the inlet pipe 21 (the rightmost outlet pipe) is defined as 22d. That is, the cross-sectional area of ​​the flow channel of 22a is larger than that of 22d. According to Bernoulli's principle, the pressure difference at the farther outlet pipe 22 is greater than the pressure difference at the closer outlet pipe 22, meaning the pressure difference within 22d is less than the pressure difference within 22a. Therefore, even if the location of 22d is far from the inlet pipe 21, water flow can still be generated due to the larger pressure difference. Furthermore, since the pressure difference within 22d is greater than that within 22a, the water flow velocity within 22d is greater than that within 22a. It is feasible to simultaneously generate water flow from the more distant 22d and the more nearby 22a. Moreover, fluid flow rate = fluid velocity x fluid cross-sectional area. The water flow within 22a has a slower velocity and a larger flow channel; the water flow within 22d has a faster velocity and a smaller flow channel. Therefore, it is feasible to generate the same flow rate from the more distant 22d and the more nearby 22a.

[0046] In the embodiments illustrated in the schematic diagrams of this application, reference is made to... Figure 5 Each branch water pipe 2332 is connected to each outlet water pipe 22 with equal flow channel cross-sectional area. That is, the flow channel cross-sectional area of ​​each outlet water pipe 22 near the inlet water pipe 21 is equal and larger than the flow channel cross-sectional area of ​​each outlet water pipe 22 far from the inlet water pipe 21. In other words, (22a=22b)<(22c=22d), in order to simplify the structure of each outlet water pipe 22 and reduce the assembly difficulty of the water circuit board 2.

[0047] In some embodiments, refer to Figure 1 and Figure 5 Each branch water pipe 2332 is connected to an equal number of outlet water pipes 22, and there are two or more of them; each spray nozzle 11 is set in groups, for example... Figure 1As shown, the four spray nozzles 11 are divided into two groups, with each group containing two spray nozzles 11. The number of spray nozzles 11 in each group is equal to the total number of water distribution pipes 2332. For example, if there are three water distribution pipes 2332, then each spray nozzle 11 is divided into three groups, with each group containing three spray nozzles 11. Correspondingly, the outlet pipes 22 also have three groups, with each group containing three outlet pipes 22. Each outlet pipe 22 on each water distribution pipe 2332 is connected to one spray nozzle 11 in each group. For example, the three outlet pipes 22 in the first group are connected to one spray nozzle 11 in the first, second, and third groups, respectively. The outlet pipes 22 in each group are staggered with the spray nozzles 11 in each group. Therefore, even if the positions of the outlet pipes 22 in each group are different, and / or the cross-sectional areas of the flow channels of the outlet pipes 22 in each group are different, the total flow rate of the water discharged from each group of spray nozzles 11 is approximately equal.

[0048] Among them, reference Figure 1 At least two sets of spray nozzles 11 are arranged opposite each other within the cleaning chamber 1. For example, if there are two sets of spray nozzles 11, they are arranged opposite each other within the cleaning chamber 1 to wet the brush discs 13 and / or rinse the cleaning tank 12 at opposite positions. Specifically, the two sets of spray nozzles 11 are distributed on both sides of the central axis surface and are symmetrically arranged. This central axis surface passes through the perpendicular bisector of the line connecting the two brush discs 13. If there are three sets of spray nozzles 11, two sets of spray nozzles 11 can be arranged opposite each other within the cleaning chamber 1, and the other set of spray nozzles 11 can be located on the central axis surface of the cleaning chamber 1.

[0049] The above, combined with Figures 1 to 7 The principle of the diversion implementation of the water circuit board 2 in this embodiment of the invention will be explained:

[0050] Each spray nozzle 11 is defined as 11a, 11b, 11c, and 11d, where 11a and 11b form one group, and 11c and 11d form another group. Water flows from nozzle 2332a to nozzles 232a and 232b, respectively, and water flows from nozzle 2332b to nozzles 232c and 232d, respectively. (Refer to...) Figure 7 Each water pipe connected to a set of water outlet pipes 22 extends in different directions. For example, water pipe e1 connected to 2332a extends to the left, and water pipe e2 connected to 2332b extends to the right. The water flow in 232a flows to 11a via 22a, the water flow in 232b flows to 11d via 22b, the water flow in 232c flows to 11b via 22c, and the water flow in 232d flows to 11c via 22d. The total flow rate of water discharged from one set of spray nozzles (11a and 11b) is equal to the total flow rate of water discharged from another set of spray nozzles (11c and 11d), so that both brush plates 13 can be wetted and the water content of the two brush plates 13 is approximately equal, so as to clean the cleaning robot evenly.

[0051] In some embodiments, reference is made to Figure 1 The cleaning base station also includes a liquid pump (not shown in the figure) for pumping out wastewater from the cleaning chamber 1. In some possible embodiments, the liquid pump may be connected to the drain pipe and / or drain outlet of the clothing processing device 3 to discharge the wastewater from the cleaning chamber 1 through the drain pipe and / or drain outlet of the clothing processing device 3. (Refer to...) Figure 4 The water circuit board 2 also includes at least a flushing pipe 24 connected to the water inlet pipe 21. The flushing pipe 24 is used to guide the water flow to the liquid pump to supply a certain amount of water into the liquid pump, thereby creating a water seal inside the liquid pump. The water seal can also play a cooling role, reducing the heat generated by friction inside the liquid pump. In other words, the water circuit board 2 provided in this embodiment of the invention can not only divert and guide the water flow, but also supply a certain amount of water into the liquid pump, thereby reducing the number of water circuit accessories connected to the liquid pump in the cleaning base station and further reducing the size of the cleaning base station.

[0052] In some embodiments, reference is made to Figure 5 The diversion pipe 23 also includes a third branch 234. The flushing pipe 24 is connected to the inlet pipe 21 or the first branch 231 via the third branch 234. In other words, the flushing pipe 24 can guide the water flow from the inlet pipe 21 through the third branch 234. The cross-sectional area of ​​the flow channel of the third branch 234 is smaller than that of the flow channel of the manifold 2331. Therefore, according to Bernoulli's principle, the pressure difference in the third branch 234 is greater than the pressure difference in the manifold 2331, so that the water flow from the inlet pipe 21 or the first branch 231 is first guided to the third branch 234.

[0053] The following combination Figures 1 to 7 The pumping principle of the cleaning chamber 1 provided in this embodiment of the invention is explained as follows: During the cleaning process of the cleaning robot at the cleaning base station, the pumping pump is not started. The water flow in the inlet pipe 21 is guided through the first branch 231 to the manifold 2331, and then through each outlet pipe 22 to each spray nozzle 11. After the cleaning robot completes its cleaning operation at the cleaning base station and leaves the cleaning chamber 1, the pumping pump starts. Due to the vacuum effect and the large pressure difference in the third branch 234, the water flow in the inlet pipe 21 is guided through the first branch 231 to the third branch 234. After the water seal in the pumping pump is established, the pumping pump is disconnected from the flushing pipe 24. The water flow in the inlet pipe 21 is again guided to the manifold 2331, and the spray nozzles 11 discharge water to flush the cleaning chamber 1, while the pumping pump pumps water simultaneously. In other words, while the pump is pumping water, the cleaning chamber 1 can be flushed simultaneously, and the pumping speed of the pump is greater than the water guiding speed of the spray nozzle 11, so that the pump can pump out the wastewater in the cleaning chamber 1.

[0054] This invention provides a cleaning device, referring to... Figure 1The cleaning equipment includes a clothing handling device 3 and the aforementioned cleaning base station. The clothing handling device 3 is used to clean clothing. The clothing handling device 3 can be a fully automatic washing machine, a semi-automatic washing machine, or a washer-dryer combo. The type of clothing handling device 3 is not limited here, as long as it can handle clothing. The cleaning base station is positioned adjacent to the clothing handling device 3. The cleaning base station can be located at the bottom of the clothing handling device 3 or next to it, as long as the cleaning base station and clothing handling device 3 can fulfill the functions described in any of the above embodiments, and the cleaning base station allows the cleaning robot to dock easily.

[0055] In some possible implementations, the cleaning base station is located at the bottom of the clothing handling device 3, allowing the liquid in the clothing handling device 3 to flow directly into the washing chamber 1 located at the bottom under the influence of gravity. In this embodiment, the cleaning base station utilizes the floor space at the bottom of the clothing handling device 3, resulting in high space utilization. (Refer to...) Figure 1 and Figure 2 The water circuit board 2 in the cleaning base station is connected to the water inlet valve 31 of the clothing processing device 3, so that the water circuit board 2 can introduce clean water from the water inlet valve 31, making the cleaning operation of the cleaning base station more efficient and reducing the possibility of residual cleaning agent on the mop of the cleaning robot.
