The nozzle is used to dispense the mixed liquid of the fourth water path and the guide water path into the clothing treatment chamber.

[0013] In some embodiments, at least a portion of the bottom wall of the pull-out space is provided with a filtration zone, which is used to collect and filter the liquid discharged from the dispenser box, so that the liquid filtered by the filtration zone flows to the guide water path, and the liquid that has not been filtered by the filtration zone is discharged through the pull-out port.

[0014] In some embodiments, the nozzle body assembly includes a nozzle body and a cover. The nozzle body includes a water channel plate, and the cover is disposed on the top side of the water channel plate, and the two enclose a first sub-cavity, a second sub-cavity, and a third sub-cavity that are not interconnected.

[0039] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0040] In the description of the embodiments of this application, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0044] This application provides a detergent dispensing device for use in a garment processing device having a garment processing chamber. This application also provides a garment processing device, including a garment processing chamber and a detergent dispensing device according to any embodiment of this application. The detergent dispensing device is used to dispense liquid containing detergent into the garment processing chamber. It should be noted that the garment processing devices in this application include, but are not limited to, top-loading washing machines, front-loading washing machines, and washer-dryer combos; this specification uses a top-loading washing machine as an example.

[0045] The garment processing chamber (not shown) is used to contain garments to be processed. For example, the garment processing device includes a housing, a cylindrical assembly, and a cover assembly. The cylindrical assembly is disposed in the housing, and the interior of the cylindrical assembly constitutes at least part of the garment processing chamber. One side of the housing has a garment inlet. The cover assembly is used to open and close the garment inlet. Users can put and take out garments into the garment processing chamber through the garment inlet.

[0046] Exemplarily, the garment handling equipment further includes a workbench disposed on the top side of the housing, with a garment inlet formed on the inner side of the workbench, and a cover assembly disposed on the workbench. A detergent dispensing device is located inside the workbench. In one embodiment, the workbench has a receiving space communicating with the garment handling chamber, the receiving space having an opening located inside the workbench, through which the detergent dispensing device is installed within the receiving space; in another embodiment, at least a portion of the workbench and the detergent dispensing device are integrally formed.

[0047] Please see Figure 1 and Figure 2 The detergent dispensing device includes a nozzle body assembly 100 and a dispenser box 200. The nozzle body assembly 100 has a pull-out space 10b, with a pull-out opening on one side in a first direction. The dispenser box 200 is pull-outably disposed within the pull-out space 10b via the pull-out opening. The dispenser box 200 is used to hold detergent; the type of detergent is not limited and can be fabric softener, laundry liquid, laundry powder, or detergent salt, etc. The user can pull out the dispenser box 200, add detergent, and then return the dispenser box 200. The pull-out direction of the dispenser box 200 can be along the front-to-back direction of the garment handling equipment (direction v in the diagram).

[0048] Please see Figure 12 and Figure 13 The detergent dispensing device also includes a first water path 100a, a second water path 100b, a third water path 100d, a first valve 41, and a second valve 42. It should be noted that the first water path 100a, the second water path 100b, the third water path 100d (and the fourth water path 100c mentioned later) refer only to the structures that facilitate the flow of liquid, and are not limited to pipe structures. The dashed lines with arrows in the attached diagram indicate the direction of liquid flow for reference.

[0049] At least two of the three water paths—first water path 100a, second water path 100b, and third water path 100d—flow through the distributor box 200. That is, after any two or all three water paths flow through the distributor box 200, the liquid mixes with the detergent to form a detergent solution, which carries the detergent. When the detergent solution enters the garment processing chamber, the detergent is dispensed. The detergent dispensing device can dispense detergent through any two or all three water paths.

[0050] For example, the first water path 100a, the second water path 100b, and the third water path 100d are used to realize different dispensing functions of the detergent dispensing device, such as dispensing different types of detergent.

[0051] For example, the water outlet of the water passage flowing through the distributor box 200 in the first water passage 100a, the second water passage 100b and the third water passage 100d includes at least a portion of a pull-out port, and the liquid flowing through the water passage of the distributor box 200 can be discharged through the pull-out port and enter the clothing processing chamber.

[0052] The first valve 41 is used to distribute water to the first water path 100a or the second valve 42. The second valve 42 is used to distribute the water distributed by the first valve 41 to the second water path 100b or the third water path 100d. The form of the water source is not limited; it can be a tap water pipe connected to the clothing processing equipment or the outlet pipe of the circulation pump of the clothing processing equipment.

[0053] Understandably, the water source can be selectively allocated to the first water path 100a, the second water path 100b, or the third water path 100d. The first valve 41 and the second valve 42 control the opening and closing of the first water path 100a, the second water path 100b, and the third water path 100d, thereby controlling the function of the detergent dispensing device.

[0054] Please see Figure 1 and Figure 2 The first valve 41 and the second valve 42 are arranged along the first direction, that is, along the pull-out direction of the dispenser box 200. This arrangement helps to reduce the size of the detergent dispensing device in directions other than the first direction. Since the nozzle body assembly 100 has reserved dimensions corresponding to the pull-out space 10b, the arrangement of the first valve 41 and the second valve 42 can reuse these dimensions, and hardly increases the installation space occupied by the detergent dispensing device, thus facilitating the installation of the detergent dispensing device in the clothing processing equipment.

[0055] For example, the garment processing equipment includes a control device, which is used to automatically control the on / off state of the first water path 100a, the second water path 100b, and the third water path 100d via a valve assembly in response to the current operating state of the garment processing equipment according to a preset program. For example, in one specific embodiment, the garment processing equipment includes a control panel, which provides a human-machine interface. Users can control the garment processing equipment through the control panel. The control panel has at least one function button. When the function button is pressed, the valve assembly switches between directing water to the first water path 100a, the second water path 100b, or the third water path 100d. Through this function button, users have more control over the garment processing equipment and can manually control the switching function of the detergent dispensing device.

[0056] In some embodiments, the detergent dispensing device further includes a third valve (not shown), which is connected to a water source and the first water path 100a. It is understood that the first valve 41 and the third valve are independent of each other; the first valve 41 can connect the first water path 100a to the water source, and the third valve can also connect the first water path 100a to the water source. The first valve 41 and the third valve are connected to different water sources, and the third valve can supply different liquids to the first water path 100a. For example, the third valve is a hot water valve, connected to a hot water source, which can supply hot water above room temperature to the first water path 100a, thereby increasing the temperature at which the detergent is dispensed, promoting detergent dissolution, and improving the washing effect on clothes.

[0057] The first valve 41 and the third valve are arranged along a second direction, which is perpendicular to the first direction. Since the first valve 41 and the second valve 42 are arranged along the first direction, the third valve can be conveniently arranged on the nozzle body assembly 100 along the second direction. In other words, the arrangement of the first valve 41 and the second valve 42 is conducive to the arrangement of the third valve on the nozzle body assembly 100.

[0058] In some embodiments, please refer to Figure 1 , Figure 6 and Figure 7 The inlet and outlet of the first valve 41 are arranged along the first direction and located on opposite sides of the first valve 41 in the first direction. This facilitates the connection of the first valve 41 to a water source. For example, when the water source is an external tap water pipe, the first valve 41 can be easily tightened onto the tap water pipe.

[0059] In some embodiments, please refer to Figure 2The dispenser box 200 includes at least one first detergent tank 201 and at least one second detergent tank 202. Two of the first water path 100a, the second water path 100b, and the third water path 100d flow through the same first detergent tank 201, and the other water path flows through the second detergent tank 202. The term "at least one" in this specification refers to one or more quantities, such as two, three, four, or more.

[0060] It should be noted that when two of the first water channels 100a, the second water channel 100b, and the third water channel 100d flow through the same first detergent tank 201, it means that the same first detergent tank 201 can hold liquid from one water channel or liquid from the other water channel.

[0061] Taking a scenario where there are two detergent tanks 201, and the first water path 100a and the second water path 100b flow through the same detergent tank 201, one detergent tank 201 can hold liquid detergent, such as laundry liquid, while the other detergent tank 201 can hold granular detergent, such as laundry powder or detergent granules. The liquid in the first water path 100a is divided into two parts, both of which flow simultaneously into the two detergent tanks 201; similarly, the liquid in the second water path 100b is divided into two parts, both of which flow simultaneously into the two detergent tanks 201. Users can add either laundry powder or laundry liquid at a time. Regardless of whether laundry powder or laundry liquid is added, water can enter through either the first water path 100a or the second water path 100b, and the liquid can flow through both detergent tanks 201, thus achieving detergent dispensing.

[0062] The second detergent tank 202 differs from the first detergent tank 201 and can hold different types of detergents. The liquid in the third sub-cavity 10a-3 allows the detergent dispensing device to dispense detergent from the second detergent tank 202, enriching the functionality of the detergent dispensing device. For example, the second detergent tank 202 is used to hold fabric softener, and the detergent dispensing device can activate the third sub-cavity 10a-3 after the clothes are cleaned to add fabric softener, making the clothes fluffy and soft.

[0063] In some embodiments, among the two water paths flowing through the same first detergent tank 201, the flow rate of one water path is greater than the flow rate of the other water path. This flow rate refers to the amount of liquid flowing through the water path and entering the dispenser box 200 per unit time. That is, taking the first water path 100a and the second water path 100b as examples, during the operation of the laundry processing equipment, the rate at which detergent is dispensed through the first water path 100a is greater than the rate at which detergent is dispensed through the second water path 100b.

[0064] For example, faster detergent dosing is suitable for garment processing equipment that processes clothes through soaking, while slower detergent dosing is suitable for garment processing equipment that processes clothes through foam washing. Slower detergent dosing allows the detergent to dissolve fully and generate foam. Therefore, different detergent dosing speeds need to be matched to different washing modes of garment processing equipment.

[0065] The flow rates of the first water path 100a and the second water path 100b are different. This means that controlling the speed of detergent dispensing does not require adjusting the flow rate of a single chamber. Instead, the first valve 41 and the second valve 42 can be used to switch between connecting the first water path 100a and the second water path 100b. This structure is simple and reliable, and more reliable than the flow rate adjustment scheme mentioned above. On the other hand, the structure of the first water path 100a and the second water path 100b is matched with their corresponding flow rates, which helps to keep the liquid flowing continuously without interruption. The detergent mixture solution is formed more evenly in the first detergent tank 201, which is beneficial for detergent dispensing and reduces residue.

[0066] In some embodiments, please refer to Figure 8 , Figure 9 , Figure 12 and Figure 13 The nozzle body assembly 100 also includes a nozzle 50a, a water guide path 100e, and a fourth water path 100c. The water guide path 100e is used to collect at least a portion of the liquid discharged from the dispenser box 200 and guide the liquid to the nozzle 50a. It should be noted that, in some embodiments, the water guide path 100e can be used to collect a detergent mixture solution formed by any one of the three water paths 100a, 100b, and 100d passing through the dispenser box 200.

[0067] Please see Figure 12 and Figure 13 The inlet of the fourth water channel 100c is connected to one of the first water channel 100a, the second water channel 100b, and the third water channel 100d. The outlet of the fourth water channel 100c is used to guide the liquid to the nozzle 50a, which in turn dispenses the mixed liquid from the fourth water channel 100c and the guide water channel 100e into the garment processing chamber. Taking the connection of the inlet of the fourth water channel 100c to the second water channel 100b as an example... Figure 12As shown, when the second water path 100b is connected to the water source, the fourth water path 100c is also connected to the water source. That is, after the second water path 100b flows through the distributor box 200 to form a detergent mixture, the detergent mixture flows through the guide water path 100e to the nozzle 50a, where it mixes with the liquid in the fourth water path 100c. Therefore, when the detergent dispensing device dispenses detergent through the second water path 100b, the detergent components dissolve better, which is more conducive to foaming, better suited to the washing mode of the garment processing equipment, and improves the washing effect.

[0068] In some embodiments, please refer to Figures 3 to 5 The outlet of the fourth water channel 100c faces the nozzle 50a. Thus, the liquid discharged from the outlet of the fourth water channel 100c can drive the mixed liquid at the nozzle 50a to flow towards the nozzle 50a, and the water outlet shape of the nozzle 50a is quite similar to the water outlet shape of the fourth water channel 100c.

[0069] In some embodiments, please refer to Figure 4 and Figure 5 The detergent dispensing device includes a turbulence structure 13711, which is disposed in the fourth water channel 100c and is used to provide a circumferential velocity component to the liquid in the fourth water channel 100c. The aforementioned provision of a circumferential velocity component means that the liquid in the fourth water channel 100c, after passing through the turbulence structure 13711, has a non-zero velocity component in the circumferential direction of the fourth water channel 100c, and the circumferential direction of the fourth water channel 100c is perpendicular to the extension direction of the fourth water channel 100c.

[0070] After passing through the turbulent structure 13711, the liquid state changes and tends to spread out in the circumferential direction, forming multiple streams of liquid with different directions. This allows for better mixing with the liquid in the guiding water channel 100e, improving mixing efficiency. It also enables the liquid at the outlet of the fourth water channel 100c to spread out in a roughly cone shape, resulting in a wider radiation range and better visual effect.

[0071] For example, the turbulence structure 13711 includes one or more helical blades for guiding the helical motion of the liquid. A helical blade is a blade with a helical shape, extending in the helical direction. After passing through the helical blades, the liquid exhibits a helical motion with a circumferential velocity component. The helical blade structure is simple, provides good turbulence control for the liquid, and has low resistance, reducing energy loss as the liquid passes through.

[0072] In some embodiments, please refer to Figure 4 and Figure 5The outlet end of the fourth water channel 100c is equipped with a narrowing section 1372a to increase the flow velocity at the outlet end of the fourth water channel 100c. It should be noted that the flow cross-sectional area of ​​the narrowing section 1372a decreases along the liquid flow direction. By limiting the flow cross-sectional area when the liquid is ejected, the narrowing section 1372a can increase the impact force of the ejected liquid, resulting in a better mixing effect, and can also propel the mixed liquid at the nozzle 50a further, improving the spraying effect.

[0073] In some embodiments, please refer to Figure 4 , Figure 8 and Figure 9 At least a portion of the bottom wall of the pull-out space 10b is provided with a filter zone 10c. The filter zone 10c is used to collect and filter the liquid discharged from the distributor box 200, so that the liquid filtered by the filter zone 10c flows into the guide water path 100e, and the liquid that has not been filtered by the filter zone 10c is discharged through the pull-out port. On the one hand, the filter zone 10c allows the liquid discharged from the distributor box 200 to pass through and enter the guide water path 100e. On the other hand, its filtration function divides the liquid discharged from the distributor box 200 into multiple fine liquid bundles, which can block incompletely dissolved detergent clumps, reduce the probability of downstream blockage, and also facilitate the contact between the liquid discharged from the distributor box 200, i.e., the detergent mixture solution, and air, increasing the air content in the liquid and promoting detergent dissolution and foaming.

[0074] The filtration zone 10c also allows unfiltered liquid to be discharged through the pull-out port. When the liquid flow rate discharged from the dispenser box 200 is large, liquid that is not filtered in time by the filtration zone 10c can overflow through the pull-out port and enter the garment processing chamber, thus preventing the liquid flow in the detergent dispensing device from becoming clogged.

[0075] For example, the filter zone 10c has a plurality of densely arranged filter pores, such as Figure 9 As shown.

[0076] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 6 The nozzle assembly 100 includes a nozzle body 10 and a cover 20. The nozzle body 10 includes a water channel plate 11. The cover 20 is disposed on the top side of the water channel plate 11, and the two enclose three non-communicating sub-cavities: a first sub-cavity 10a-1, a second sub-cavity 10a-2, and a third sub-cavity 10a-3. That is, liquid in one sub-cavity will not enter the other two sub-cavities. The first water channel 100a flows through the first sub-cavity 10a-1, the second water channel 100b flows through the second sub-cavity 10a-2, and the third water channel 100d flows through the third sub-cavity 10a-3. The three water channels do not interfere with each other.

[0077] In this embodiment, the first sub-cavity 10a-1, the second sub-cavity 10a-2, and the third sub-cavity 10a-3 are not pre-installed pipe structures, but are assembled and enclosed by the water channel plate 11 and the cover 20. This arrangement facilitates the rational layout of the first sub-cavity 10a-1, the second sub-cavity 10a-2, and the third sub-cavity 10a-3, improving space utilization. For example, a first water-dividing rib 111 is formed on one side of the water channel plate 11, and a second water-dividing rib 21 is formed on the side of the cover 20 near the water channel plate 11. The first water-dividing rib 111 and the second water-dividing rib 21 cooperate to enclose the first sub-cavity 10a-1, the second sub-cavity 10a-2, or the third sub-cavity 10a-3.

[0078] For example, please refer to Figure 6 and Figure 10 The water circuit board 11 has at least one first through hole 11a-1, at least one second through hole 11a-2, and at least one third through hole 11a-3. The first sub-cavity 10a-1 is connected to the pull-out space 10b through at least one first through hole 11a-1, the second sub-cavity 10a-2 is connected to the pull-out space 10b through at least one second through hole 11a-2, and the third sub-cavity 10a-3 is connected to the pull-out space 10b through at least one third through hole 11a-3. It is understood that after the liquid from the first sub-cavity 10a-1 flows out into the pull-out space 10b, it falls into the first detergent tank 201; after the liquid from the second sub-cavity 10a-2 flows out into the pull-out space 10b, it falls into the first detergent tank 201; and after the liquid from the third sub-cavity 10a-3 flows out into the pull-out space 10b, it falls into the second detergent tank 202. This eliminates the need for additional drainage pipes and helps save space inside the detergent dispensing device.

[0079] In some embodiments, please refer to Figure 6 and Figure 8 The nozzle body 10 includes a first sidewall 12 and a side structure 13. The pull-out space 10b and the sidewall structure are located on opposite sides of the first sidewall 12 in a second direction. That is, the outer surface of the first sidewall 12 near the pull-out space 10b at least partially constitutes the inner wall of the pull-out space 10b, while the side structure 13 is located on the side of the first sidewall 12 away from the pull-out space 10b. In this way, the size of the nozzle body assembly 100 in directions other than the second direction can be reduced, making it easier to arrange the device in the workbench of the garment processing equipment. The second direction can be the left-right direction of the garment processing equipment.

[0080] like Figure 2 and Figure 8 As shown, the first valve 41 and the second valve 42 are both located on the top side of the side structure 13, so as to avoid increasing the size of the part corresponding to the pull-out space 10b as much as possible.

[0081] In some embodiments, please refer to Figure 2The second valve 42 is located on the top side of the cover 20. The inlet and outlet of the second valve 42 are both located on the bottom side of the second valve 42 and penetrate the cover 20. That is, the water inlet and outlet of the second valve 42 are roughly along the height of the clothing processing equipment. The structure of the second valve 42 does not occupy a large space in the horizontal direction.

[0082] In some embodiments, please refer to Figure 6 and Figure 8 A portion of the cover 20 extends to the top side of the side structure 13. The detergent dispensing device includes a bottom cover 30, which is located on the bottom side of the nozzle body 10 and extends to the bottom side of the side structure 13. The cover 20, side structure 13, and bottom cover 30 together enclose a portion of the first water path 100a, a portion of the second water path 100b, and a portion of the third water path 100d. In other words, a portion of the first water path 100a, a portion of the second water path 100b, and a portion of the third water path 100d are not pre-installed pipe structures, but are formed after assembly using the cover 20, side structure 13, and bottom cover 30. This arrangement facilitates the rational layout of the first water path 100a, the second water path 100b, and the third water path 100d, improving space utilization.

[0083] For example, the water channel 100e is also enclosed by the side structure 13 and the bottom cover 30.

[0084] Exemplary examples, in some embodiments, the nozzle 50a is disposed on the nozzle body 10. In other embodiments, please refer to... Figure 3 The nozzle 50a is located on the bottom cover 30, which facilitates the spraying of water towards the clothing treatment chamber.

[0085] For example, a portion of the workbench forms at least a portion of the bottom cover 30; or, a portion of the workbench forms at least a portion of the nozzle body 10; or, a portion of the workbench forms at least a portion of the box cover 20. That is, a portion of the workbench and at least a portion of the detergent dispensing device are integrally formed, thus making the structure of the garment handling equipment compact.

[0086] In some embodiments, please refer to Figures 11 to 13The side structure 13 includes a bottom wall 132, a side enclosure 133, and a partition wall 134. The partition wall 134 divides the area enclosed by the side enclosure 133 and the bottom wall 132 into a first space 134a-1 and a second space 134a-2. The partition wall 134 is provided with a through hole 134a, which connects the first space 134a-1 and the second space 134a-2. The first space 134a-1 is connected to the second sub-cavity 10a-2. The first water passage 100a flows through a portion of the second space 134a-2 and the first space 134a-1, while the fourth water passage 100c flows through another portion of the second space 134a-2. That is, the second water passage 100b and the fourth water passage 100c are connected through the second space 134a-2. When the second water passage 100b is connected to a water source, it can also provide a water source for the fourth water passage 100c. In this embodiment, no additional piping structure is required to set up the fourth water channel 100c, which can save the space occupied by the fourth water channel 100c.

[0087] It should be noted that the bottom wall portion 132 is not limited to being located on the bottom side of the side structure 13.

[0088] In some embodiments, please refer to Figure 5 and Figure 11 The bottom wall portion 132 of the second space 134a-2 is provided with a first water outlet 132a. The side structure 13 includes a guide structure disposed below the bottom wall portion 132. One end of the guide structure is connected to the first water outlet 132a, and the outlet of the other end is the outlet of the fourth water channel 100c. The space within the guide structure defines a portion of the fourth water channel 100c. The water outlet direction of the fourth water channel 100c is approximately along the extension direction of the guide structure. The liquid in the second space 134a-2 enters the guide structure through the first water outlet 132a of the bottom wall portion 132 by immersion. The guide structure remains filled with liquid, so that the water outlet of the fourth water channel 100c continuously sprays liquid without interruption.

[0089] In some embodiments, please refer to Figures 3 to 5 The flow guiding structure includes a split cylindrical section 1371 and a nozzle section 1372. The cylindrical section 1371 connects the first water outlet 132a and the nozzle section 1372. The nozzle section 1372 bends towards the nozzle 50a in a direction away from the cylindrical section 1371 to spray water towards the nozzle 50a. The nozzle section 1372 is mounted on the cylindrical section 1371, and its outlet orientation can be adjusted according to the required water spray direction.

[0090] The space within the nozzle section 1372 forms a narrowed section 1372a, and the flow cross-sectional area of ​​the narrowed section 1372a decreases along the liquid flow direction. That is, the narrowed section 1372a is provided at the outlet end of the fourth water path 100c. In this embodiment, the cylinder section 1371 and the nozzle section 1372 extend into the space between the bottom wall section 132 and the bottom cover 30. The liquid ejected from the outlet of the nozzle section 1372 has a suction effect on the surrounding liquid, which can promote mixing and foaming.

[0091] For example, a turbulent flow structure 13711 is provided inside the cylindrical section 1371, and the turbulent flow structure 13711 is located upstream of the narrowed section 1372a.

[0092] For example, please refer to Figure 4 and Figure 9 The bottom side of the nozzle body 10 and / or side structure 13, together with the bottom cover 30, encloses a guide cavity 100e-1. The guide cavity 100e-1 defines a guide water path 100e. A guide structure extends into the guide cavity 100e-1, and the nozzle portion 1372 is spaced apart from the inner wall of the guide cavity 100e-1. It can be understood that the detergent mixture discharged from the filter zone 10c enters the guide cavity 100e-1, is collected by the bottom cover 30, and flows along the guide water path 100e to the nozzle 50a.

[0093] In some embodiments, please refer to Figures 7 to 9 The bottom wall portion 132 corresponding to the second space 134a-2 is provided with a first water inlet 132b. The bottom side of the side structure 13 and the bottom cover 30 define a water passage 30a-3. The first water inlet 132b connects the second space 134a-2 and the water passage 30a-3. After the liquid in the water passage 30a-3 overflows, it enters the second space 134a-2 through the first water inlet 132b, so that the second space 134a-2 can guide the liquid to the first space 134a-1 and the flow guiding structure, and has a large water pressure, making it difficult to interrupt the flow. For example, the second valve 42 is connected to the water passage 30a-3, and the second water path 100b flows through the water passage 30a-3, the first water inlet 132b, the through hole 134a, and the first space 134a-1.

[0094] In some embodiments, please refer to Figure 8 , Figure 9 , Figure 12 and Figure 13The side structure 13 includes a support plate portion 131 and a first enclosure portion 135. The first enclosure portion 135 is connected to the first side wall 12 and together encloses a first water inlet cavity 135a. The support plate portion 131 and the bottom cover 30 together enclose a first channel 30a-1. The support plate portion 131 is provided with a first water outlet 131a, which connects the first water inlet cavity 135a and the first channel 30a-1. The first water inlet cavity 135a connects to the first sub-cavity 10a-1. When the liquid in the first channel 30a-1 overflows, it enters the first water inlet cavity 135a through the first water outlet 131a, so that the first water inlet cavity 135a can guide the liquid to the first sub-cavity 10a-1, and has a large water pressure, making it less likely to interrupt the flow. For example, the first valve 41 is connected to the first channel 30a-1, and the first water path 100a flows through the first channel 30a-1, the first water outlet 131a, the first water inlet chamber 135a and the first sub-chamber 10a-1.

[0095] In some embodiments, please refer to Figure 8 , Figure 9 , Figure 12 and Figure 13 The side structure 13 also includes a second enclosure 136, which connects to the first side wall 12 and together encloses a second water inlet cavity 136a. A support plate 131 and a bottom cover 30 together enclose a second channel 30a-2. The support plate 131 is provided with a second water outlet 131b, which connects the second water inlet cavity 136a and the second channel 30a-2. The second water inlet cavity 136a connects to a third sub-cavity 10a-3. When the liquid in the second channel 30a-2 overflows, it enters the second water inlet cavity 136a through the second water outlet 131b, allowing the second water inlet cavity 136a to guide the liquid to the third sub-cavity 10a-3, and providing high water pressure to prevent flow interruption. For example, the second valve 42 is connected to the second channel 30a-2, and the third water path 100d flows through the second channel 30a-2, the second water outlet 131b, the second water inlet 136a, and the third sub-cavity 10a-3.

[0096] It should be noted that, for ease of identification and understanding, Figure 12 and Figure 13 The first inlet 132b, the first outlet 131a, and the second outlet 131b are highlighted by shaded areas, but have no other limiting meaning.
