Description

Technical Field

[0001] This disclosure relates to the field of clothing processing technology, specifically to a dispensing device and clothing processing equipment. Background Technology

[0002] In related technologies, the dispensing device of a garment processing equipment is used to dispense detergent into the drum. For example, water from the inlet pipe of the garment processing equipment can flush the detergent from the dispensing device into the drum. Currently, the reliability of the dispensing device is relatively poor. Utility Model Content

[0003] The purpose of this disclosure is to provide a dispensing device that has high reliability.

[0004] To achieve the above objectives, this disclosure provides a dispensing device, comprising: The first material box includes a first mixing chamber, and a first water inlet, a first feeding chamber and a first water outlet, all of which are connected to the first mixing chamber; The second material box includes a second mixing chamber, and a second water outlet, a second feeding chamber, and a second water inlet, all of which are connected to the second mixing chamber. A connecting structure, connected in series between the first outlet and the second inlet; and A negative pressure compensation structure is connected to the connecting structure and is used to introduce compensation gas into the connecting structure.

[0005] In some possible implementations, the first material box and the second material box are spaced apart along a preset direction, and the negative pressure compensation structure is disposed between the first material box and the second material box in the preset direction.

[0006] In some possible implementations, the communication structure includes a tubular box disposed between the first material box and the second material box in a predetermined direction, and the negative pressure compensation structure is connected to the tubular box.

[0007] In some possible implementations, the tubing includes a connector for connecting to the housing of the garment processing equipment.

[0008] In some possible implementations, the communication structure includes a first pipe and a second pipe, the pipe box being connected to a first outlet via the first pipe and to a second inlet via the second pipe.

[0009] In some possible implementations, the first material box and the second material box are spaced apart along a preset direction, the preset direction being the left-right direction, and the connecting structure and the negative pressure compensation structure are disposed near the front side of the first material box and the front side of the second material box.

[0010] In some possible implementations, the negative pressure compensation structure includes a compensation element, the compensation element includes a compensation cavity, the compensation cavity is provided with compensation gas, and the compensation cavity is in communication with the communication structure.

[0011] In some possible implementations, the compensation element is disposed on the outside of the connecting structure.

[0012] In some possible implementations, the first material box and the second material box are spaced apart along a preset direction, the preset direction being the left-right direction, and the compensation member is connected to the upper side of the connecting structure.

[0013] In some possible implementations, the compensation member has a first end and a second end disposed opposite to each other along its own extension direction, the first end being closed and the second end having an opening that connects the compensation cavity and the connecting structure.

[0014] In some possible implementations, the compensation member has a first end and a second end disposed opposite to each other along its own extension direction, both the first end and the second end having an opening that connects the compensation cavity and the connecting structure.

[0015] In some possible implementations, the compensation element is constructed as a compensation tube, the compensation tube is constructed as a U-shaped tube, and the opposite ends of the U-shaped tube are constructed as the first end and the second end.

[0016] According to a second aspect of this disclosure, a garment handling apparatus is provided, including the dispensing device as described above.

[0017] In some possible implementations, the garment handling device includes a first tube, a second tube, and a third tube, with the second tube positioned to the upper left of the first tube and the third tube positioned to the upper right of the first tube.

[0018] In some possible implementations, the volume of the second cylinder is smaller than the volume of the first cylinder, and / or the volume of the third cylinder is smaller than the volume of the first cylinder.

[0019] Through the above technical solution, in the dispensing device provided by this disclosure, the first feeding chamber can dispense washing liquid into the first mixing chamber. When the water supply flows through the first mixing chamber, the first mixing chamber can achieve mixing of the water supply and the washing liquid. Similarly, the second feeding chamber can dispense washing liquid into the second mixing chamber. When the water supply flows through the second mixing chamber, the second mixing chamber can achieve mixing of the water supply and the washing liquid.

[0020] When the water intake in the first mixing chamber ends, the water recedes from the first mixing chamber. When the liquid in the first mixing chamber flows out of the first mixing chamber quickly, a brief water hammer effect occurs in the first mixing chamber. This causes a negative pressure to be generated in the first mixing chamber, for example, at the mixing point of the first mixing chamber and the first feeding chamber. As a result, a small amount of washing liquid in the first feeding chamber may be accidentally drawn into the first mixing chamber. Therefore, when the garment processing equipment performs the next washing operation, it will lead to the over-addition of washing liquid, or when the garment processing equipment performs the rinsing mode, it will lead to the incorrect addition of washing liquid.

[0021] To address this, this disclosure adds a negative pressure compensation structure. When the liquid in the first mixing chamber flows out rapidly, the negative pressure compensation structure can introduce compensation gas into the connecting structure. This gas can then replenish the first mixing chamber through the connecting structure. This reduces or even prevents negative pressure from forming in the first mixing chamber, for example, preventing negative pressure from forming at the mixing point between the first mixing chamber and the first feeding chamber. This reduces or even prevents the washing liquid in the first feeding chamber from being accidentally drawn into the first mixing chamber. This prevents excessive or incorrect addition of washing liquid, thereby improving the reliability of the feeding device.

[0022] Similarly, when the liquid in the second mixing chamber flows out of the second mixing chamber rapidly, the negative pressure compensation structure can introduce compensation gas into the connecting structure. This gas can then be replenished into the second mixing chamber through the connecting structure. This can reduce or even prevent negative pressure from being generated in the second mixing chamber, for example, preventing negative pressure from being generated at the mixing point of the second mixing chamber and the second feeding chamber. This can reduce or even prevent the washing liquid in the second feeding chamber from being accidentally drawn into the second mixing chamber. This can also prevent the washing liquid from being added in excess or incorrectly.

[0023] Furthermore, by connecting the negative pressure compensation structure to the connecting structure, on the one hand, the connecting structure can provide an installation base for the negative pressure compensation structure and facilitate the connection between the two; on the other hand, this arrangement can prevent the negative pressure compensation structure from being too close to one of the first and second mixing chambers when it is placed on the first or second material box, thus preventing the negative pressure compensation structure from being too far from the other. In other words, connecting the negative pressure compensation structure to the connecting structure can make the negative pressure compensation structure closer to both the first and second material boxes, which allows the compensation gas to quickly reach the first mixing chamber and the second mixing chamber, thereby improving the reliability of the negative pressure compensation structure.

[0024] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0027] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0028] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "front," "back," "left," and "right" are used based on the definition of the garment handling equipment, which can be found in the following references. Figure 1 , Figure 2 , Figure 7 as well as Figure 8 In the context of clothing processing equipment, the terms "up," "down," "front," "back," "left," and "right" are used. The up / down direction can be referenced to the direction of gravity of the equipment, and the left / right direction can be referenced to the width of the equipment. In the front / back direction, "front" can be understood as the side of the equipment facing the user, and "back" as the side away from the user. The gate of the clothing processing equipment is typically located on the front side. "Inner" and "outer" refer to the inner and outer contours of each component. "Upstream" and "downstream" are defined based on the direction of water flow. The terms "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the following description, when referring to accompanying drawings, the same reference numerals in different drawings denote the same or similar elements, which will not be repeated here.

[0029] According to some embodiments of this disclosure, reference is made to Figures 1 to 8 As shown, this disclosure provides a dispensing device for dispensing detergent into the drum of a garment processing device. The detergent can be laundry liquid, fabric softener, disinfectant, laundry pods, fragrance enhancer, bleach, etc., and this disclosure does not limit the types. The dispensing device can have a switchable dispensing mode and a water dispensing mode. In the dispensing mode, the dispensing device mixes external water with the detergent and then dispenses it into the drum of the garment processing device; in the water dispensing mode, the dispensing device dispenses external water without detergent mixture into the drum to rinse the washed clothes. The more types of detergent the dispensing device can dispense, the more thoroughly the clothes can be cleaned, thereby improving the user experience.

[0030] In some embodiments of this disclosure, reference is made to Figure 1 and Figure 2 As shown, the dispensing device may include: a first material box 1, including a first water inlet 11 and a first water outlet 14; a second material box 2, including a second water outlet 21 and a second water inlet 24; and a connecting structure 3, which is connected in series between the first water outlet 14 and the second water inlet 24, that is, the connecting structure 3 connects the first material box 1 and the second material box 2 in series.

[0031] Through the above technical solution, in the dispensing device provided in this disclosure, the first material box 1 can receive water from the outside through the first water inlet 11. The water can enter the first material box 1 through the first water inlet 11, and then mix with the washing liquid in the first material box 1. The mixed water can flow into the connecting structure 3 through the first water outlet 14, and then flow into the second material box 2 through the second water inlet 24 via the connecting structure 3. After that, the mixed water can mix with the washing liquid in the second material box 2, and then the mixture contains the first... The detergent in the first detergent box 1 and the detergent in the second detergent box 2 can flow out of the second detergent box 2 through the second water outlet 21 and flow into the drum of the garment processing equipment. Therefore, compared with the water supply that mixes the detergent in the first detergent box 1 alone, or the water supply that mixes the detergent in the second detergent box 2 alone, the dispensing device of this disclosure can provide external water supply that mixes both the detergent in the first detergent box 1 and the detergent in the second detergent box 2. This can increase the variety of detergents dispensed into the drum, thereby improving the user experience.

[0032] In addition, regarding the water supply, since the first material box 1, the connecting structure 3 and the second material box 2 are connected in series, the water supply can flow through the first material box 1, the connecting structure 3 and the second material box 2 in sequence. This facilitates the water supply to mix the washing liquid in the first material box 1 and the washing liquid in the second material box 2 in sequence, which is convenient for stable dispensing of various types of washing liquids.

[0033] It should be noted that the first feed box 1 and the second feed box 2 can be filled with different types of detergents during use. The first feed box 1 can contain at least one detergent, for example, two detergents. In some embodiments, the first feed box 1 may include at least two first feeding chambers 13, each containing one type of detergent. Similarly, the second feed box 2 can contain at least one detergent, for example, two detergents. In some embodiments, the second feed box 2 may include at least two second feeding chambers 23, each containing one type of detergent. This disclosure does not impose any limitations on this.

[0034] It should also be noted that when the first material box 1 and the second material box 2 are in use, the external water supply can be mixed separately with the washing liquid in the first material box 1. When the water flows through the second material box 2, the mixing of the mixed water supply with the washing liquid in the second material box 2 is eliminated. This allows for the separate dispensing of the washing liquid in the first material box 1. Similarly, when the external water supply flows through the first material box 1, the mixing of the water supply with the washing liquid in the first material box 1 is eliminated. Subsequently, the water supply that has not been mixed with the washing liquid in the first material box 1 can be mixed separately with the washing liquid in the second material box 2. This allows for the separate dispensing of the washing liquid in the second material box 2. Therefore, the dispensing device of this disclosure can realize multiple dispensing modes, including single-material box dispensing and double-material box dispensing, allowing users to choose according to their needs.

[0035] In some embodiments of this disclosure, reference is made to Figures 1 to 4 As shown, the first material box 1 may include a first mixing chamber 12 and a first feeding chamber 13, with the first inlet 11, the first outlet 14, and the first feeding chamber 13 all connected to the first mixing chamber 12; the second material box 2 includes a second mixing chamber 22 and a second feeding chamber 23, with the second outlet 21, the second inlet 24, and the second feeding chamber 23 all connected to the second mixing chamber 22. A connecting structure 3 connects the first mixing chamber 12 and the second mixing chamber 22 in series.

[0036] Through the above technical solution, in the dispensing device provided in this disclosure, water can enter the first mixing chamber 12 of the first material box 1 through the first water inlet 11, and the first feeding chamber 13 can dispense washing liquid into the first mixing chamber 12. In this way, when the water flows through the first mixing chamber 12, it can mix with the washing liquid in the first material box 1. Subsequently, the mixed water can flow into the second mixing chamber 22 of the second material box 2 through the connecting structure 3. The second feeding chamber 23 can dispense washing liquid into the second mixing chamber 22. In this way, when the water flows through the second mixing chamber 22, it can mix with the washing liquid in the second material box 2. Subsequently, the water mixed with the washing liquid in the first material box 1 and the detergent in the second material box 2 can flow out of the second mixing chamber 22 through the second water outlet 21, and then out of the second material box 2, and into the cylinder of the clothing processing equipment.

[0037] In some embodiments of this disclosure, reference is made to Figures 1 to 4 As shown, the dispensing device may include a water tank 4, which may include an outlet 41 and a return water inlet 42. The outlet 41 is connected upstream of the first inlet 11, and the return water inlet 42 is connected downstream of the second outlet 21. Thus, the water tank 4 is adapted to distribute external water supply to the first inlet 11 (i.e., to the first feed box 1) through the outlet 41, and to receive water mixed with detergent through the return water inlet 42. Therefore, the water tank 4 can integrate the water inlet and return water functions of the dispensing device. This facilitates water flow in the dispensing device and also allows for modular design, thus facilitating assembly of the dispensing device and consequently, the assembly of the garment processing equipment.

[0038] In some implementations, reference Figures 1 to 4 As shown, the first material box 1 and the second material box 2 can be spaced apart along a preset direction. For example, the preset direction can be the left and right direction, and the first material box 1 and the second material box 2 can be spaced apart along the left and right direction.

[0039] In some implementations, reference Figures 1 to 4 As shown, the water box 4 can have a first side 43 and a second side 44 arranged opposite to each other along the aforementioned preset direction. The first side 43 is located near the first material box 1 and has an outlet 41; the second side 44 is located near the second material box 2 and has a return water inlet 42. Thus, the outlet 41 and the return water inlet 42 can be located on opposite sides of the water box 4. Furthermore, the above arrangement allows the outlet 41 to be close to the first inlet 11 of the first material box 1, thereby facilitating the supply of external water to the water box 4. The above arrangement also allows the return water inlet 42 to be close to the second outlet 21 of the second material box 2, thereby facilitating the return of water mixed with washing liquid to the water box 4. Therefore, the above arrangement facilitates the flow of water in the dispensing device.

[0040] In some implementations, reference Figures 1 to 4 As shown, the dispensing device may include a water inlet valve 5, which is adapted to receive external water supply. The water box 4 may have a water inlet chamber 45, which connects the water inlet valve 5 and the outlet 41. In this way, the water inlet valve 5 can dispense external water into the water box 4, specifically into the water inlet chamber 45 of the water box 4. Subsequently, the water in the water inlet chamber 45 can flow through the outlet 41 to the first water inlet 11, and then into the first feed box 1.

[0041] In some implementations, reference Figures 1 to 4As shown, the water tank 4 may include at least one water inlet 46, which is connected downstream of the return water inlet 42 and is used to connect with the drum of the laundry treatment device. In this way, the water mixed with detergent flows into the water tank 4 through the return water inlet 42 and then flows out of the water tank 4 through the water inlet 46, and is then dispensed into the drum, thereby enabling the dispensing device to dispense detergent into the drum.

[0042] In some implementations, reference Figures 1 to 4 As shown, the number of water inlets 46 can be at least two, meaning the laundry treatment device can include at least two drums. In this embodiment where there are at least two water inlets 46, the dispensing device can include a reversing valve 6 connected between the return water inlet 42 and the water inlet 46, for distributing water from the return water inlet 42 to at least one water inlet 46. Thus, the reversing valve 6 can distribute water mixed with detergent to the corresponding water inlet 46 as needed, thereby enabling the dispensing of detergent to the corresponding drum.

[0043] In some embodiments, reference Figures 1 to 4 As shown, the water box 4 can have a return water chamber 47 and a supply water chamber 48. The return water port 42 is connected to the return water chamber 47, and the supply water port 46 is connected to the corresponding supply water chamber 48. The reversing valve 6 is connected between the return water chamber 47 and any supply water chamber 48. In this way, the supply water mixed with washing liquid can enter the return water chamber 47 through the return water port 42, and then enter the reversing valve 6. After that, the reversing valve 6 can release the supply water mixed with washing liquid into the corresponding supply water chamber 48 as needed. Then, the supply water mixed with washing liquid in the supply water chamber 48 can flow out through the supply water port 46 and then be released into the corresponding cylinder. Thus, the return water chamber 47 and the supply water chamber 48 in the water box 4 can be used in conjunction with the supply valve to realize the distribution of water supply.

[0044] In some implementations, reference Figures 1 to 4 As shown, the number of water inlets 46 is at least two, including a first water inlet 10 and a second water inlet 20. The first water inlet 10 is used to connect to the first drum 100 of the laundry processing device, and the second water inlet 20 is used to connect to the second drum 200 of the laundry processing device. Thus, the dispensing device can dispensing detergent into both the first drum 100 and the second drum 200. The laundry processing device can be configured as a twin-drum laundry processing device.

[0045] In some embodiments, reference Figures 1 to 4As shown, at least two water inlets 46 may include a third water inlet 30, which is used to connect to the third drum 300 of the laundry processing device. Thus, the dispensing device can also dispense detergent into the third drum 300. The laundry processing device can be configured as a three-drum laundry processing device.

[0046] In some implementations, reference Figures 1 to 4 As shown, the specific water circuit principle of the dispensing device is as follows: After receiving external water supply, the inlet valve 5 directs the water from the outside into the water box 4, specifically into the inlet chamber 45 of the water box 4. The water in the inlet chamber 45 then flows through the outlet 41 to the first inlet 11, and then into the first feed box 1. The water then mixes with the detergent in the first feed box 1, and the mixed water flows through the first outlet 14 into the connecting structure 3, and then through the connecting structure 3 into the second feed box 2 via the second inlet 24. The mixed water then mixes with the detergent in the second feed box 2. The water mixed with the detergent from the first feed box 1 and the detergent from the second feed box 2 then flows out of the second feed box 2 through the second outlet 21 and into the water box 4, specifically into the return water chamber 47. Subsequently, the water supply in the return water chamber 47 enters the reversing valve 6. Then, the reversing valve 6 can release the water mixed with washing liquid into the corresponding water supply chamber 48 as needed. Then, the water mixed with washing liquid in the water supply chamber 48 can flow out through the water supply port 46 and be released into the corresponding cylinder. In this way, the dispensing device can release washing liquid into the cylinder, such as into the first cylinder 100, the second cylinder 200, and the third cylinder 300.

[0047] In some implementations, reference Figures 1 to 4 as well as Figure 7 and Figure 8 As shown, the first material box 1 and the second material box 2 can be spaced apart along a preset direction, and the water box 4 has a first side 43 and a second side 44 arranged opposite to each other along the preset direction. The volume of the second cylinder 200 and the volume of the third cylinder 300 can both be smaller than the volume of the first cylinder 100. The first water inlet 10 can be arranged on the first side 43 of the water box 4, and the second water inlet 20 and the third water inlet 30 can be arranged on the second side 44 of the water box 4.

[0048] Since the first cylinder 100 has a large volume, it requires a large amount of water and washing liquid. Therefore, the first water inlet 10 is set separately on the first side 43 to ensure the arrangement space of the first water inlet 10, thereby ensuring the diameter or cross-sectional area of ​​the first water inlet 10. This ensures that enough water and washing liquid can be supplied to the first cylinder 100.

[0049] By setting the second water inlet 20 and the third water inlet 30 on the same side, the second water inlet 20 and the third water inlet 30 can be centrally located. This facilitates the simultaneous flow of water from the second water inlet 20 and the third water inlet 30 on the second side 44, and also makes full use of the space on the second side 44.

[0050] In some embodiments, the water inlet valve 5 can be arranged on the first side 43 of the water box 4 to facilitate water flow between the water inlet valve 5 and the first water inlet 11, and the reversing valve 6 can be arranged on the second side 44 of the water box 4 to facilitate water flow through the water supply port 46, such as facilitating water flow through the first water supply port 10, the second water supply port 20, and the third water supply port 30.

[0051] In some embodiments, reference Figures 1 to 4 As shown, both the second water inlet 20 and the third water inlet 30 can include a main inlet 461 and a defoaming inlet 462. Thus, the main inlet 461 primarily functions to add water and detergent to the second cylinder 200 or the third cylinder 300, while the defoaming inlet 462 assists in adding water to the second cylinder 200 or the third cylinder 300 to quickly eliminate foam within them.

[0052] In some embodiments of this disclosure, reference is made to Figures 1 to 8 As shown, the dispensing device may include a negative pressure compensation structure 7, which is connected to the connecting structure 3 and is used to introduce compensation gas into the connecting structure 3.

[0053] Through the above technical solution, in the dispensing device provided by this disclosure, the first feeding chamber 13 can dispense washing liquid into the first mixing chamber 12. When the water supply flows through the first mixing chamber 12, the first mixing chamber 12 can achieve the mixing of water supply and washing liquid. Similarly, the second feeding chamber 23 can dispense washing liquid into the second mixing chamber 22. When the water supply flows through the second mixing chamber 22, the second mixing chamber 22 can achieve the mixing of water supply and washing liquid.

[0054] When the water intake in the first mixing chamber 12 ends, the water recedes from the first mixing chamber 12. When the liquid in the first mixing chamber 12 flows out of the first mixing chamber 12 quickly, a brief water hammer effect occurs in the first mixing chamber 12. This causes a negative pressure to be generated in the first mixing chamber 12. For example, a negative pressure will be generated at the mixing point of the first mixing chamber 12 and the first feeding chamber 13. As a result, a small amount of washing liquid in the first feeding chamber 13 may be accidentally drawn into the first mixing chamber 12. Therefore, when the garment processing equipment performs the next washing operation, it will lead to the over-addition of washing liquid, or when the garment processing equipment performs the rinsing mode, it will lead to the incorrect addition of washing liquid.

[0055] To address this, this disclosure adds a negative pressure compensation structure 7. When the liquid in the first mixing chamber 12 flows out of the first mixing chamber 12 rapidly, the negative pressure compensation structure 7 can introduce compensation gas into the connecting structure 3. This gas can then be replenished into the first mixing chamber 12 via the connecting structure 3. This reduces or even prevents negative pressure from being generated in the first mixing chamber 12, for example, preventing negative pressure from being generated at the mixing point of the first mixing chamber 12 and the first feeding chamber 13. This reduces or even prevents the washing liquid in the first feeding chamber from being accidentally drawn into the first mixing chamber 12. This prevents excessive or incorrect addition of washing liquid, thereby improving the reliability of the feeding device.

[0056] Similarly, when the liquid in the second mixing chamber 22 flows out of the second mixing chamber 22 rapidly, the negative pressure compensation structure 7 can introduce compensation gas into the connecting structure 3. This gas can then be replenished into the second mixing chamber 22 through the connecting structure 3. This can reduce or even prevent the generation of negative pressure in the second mixing chamber 22, for example, preventing negative pressure from being generated at the mixing point of the second mixing chamber 22 and the second feeding chamber 23. This can reduce or even prevent the washing liquid in the second feeding chamber from being accidentally drawn into the second mixing chamber 22. This can also prevent the washing liquid from being added in excess or incorrectly.

[0057] Furthermore, by connecting the negative pressure compensation structure 7 to the connecting structure 3, on the one hand, the connecting structure 3 can provide an installation base for the negative pressure compensation structure 7 and facilitate the connection between the two; on the other hand, this arrangement can prevent the negative pressure compensation structure 7 from being too close to one of the first mixing chamber 12 and the second mixing chamber 22 when it is set on the first material box 1 or the second material box 2, thus preventing the negative pressure compensation structure 7 from being too far from the other. In other words, connecting the negative pressure compensation structure 7 to the connecting structure 3 can make the negative pressure compensation structure 7 closer to both the first material box 1 and the second material box 2, which allows the compensation gas to quickly reach the first mixing chamber 12 and the second mixing chamber 22, thereby improving the reliability of the negative pressure compensation structure 7.

[0058] It should be noted that this disclosure does not limit the specific structure of the negative pressure compensation structure 7, which will be described in detail in the following embodiments.

[0059] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 7 as well as Figure 8As shown, the first material box 1 and the second material box 2 are spaced apart along a preset direction, and the negative pressure compensation structure 7 can be disposed between the first material box 1 and the second material box 2 in the preset direction. In this way, on the one hand, the arrangement space between the first material box 1 and the second material box 2 can be used to arrange the negative pressure compensation structure 7, thereby improving the utilization rate of the arrangement space in the garment processing equipment; on the other hand, this arrangement makes the negative pressure compensation structure 7 close to both the first material box 1 and the second material box 2, thereby shortening the path of the compensation gas to the first material box 1 and the second material box 2.

[0060] In some implementations, reference Figure 1 , Figure 2 , Figures 5 to 8 As shown, the connecting structure 3 may include a tubing box 31. In a preset direction, the tubing box 31 may be disposed between the first material box 1 and the second material box 2, and the negative pressure compensation structure 7 is connected to the tubing box 31. In this way, the tubing box 31 can provide an installation base for the negative pressure compensation structure 7 and support the negative pressure compensation structure 7, avoiding the connection between the negative pressure compensation structure 7 and the flexible hose of the connecting structure 3, which would cause the negative pressure compensation structure 7 to be easily displaced and deformed.

[0061] In some embodiments, the tube box 31 may have a communicating cavity that can communicate with the negative pressure compensation structure 7 and can be connected between the first tube 32 and the second tube 33 described below, which is not limited in this disclosure.

[0062] In some embodiments, reference Figure 1 , Figure 2 , Figures 5 to 8 As shown, the tube box 31 may include a connecting part 311 for connecting to the housing of the garment processing equipment. In this way, the connecting part 311 can be used to fix the tube box 31 to the housing, thus achieving relative fixation of both the position of the tube box 31 and the position of the negative pressure compensation structure 7, thereby improving the reliability of the dispensing device.

[0063] In some embodiments, connecting portions 311 may be provided on both sides of the tube box 31 along a preset direction, and this disclosure does not limit this.

[0064] In some implementations, reference Figure 1 , Figure 2 , Figures 5 to 8As shown, the connecting structure 3 includes a first pipe 32 and a second pipe 33. The pipe box 31 is connected to the first outlet 14 through the first pipe 32, that is, the pipe box 31 is connected to the first mixing chamber 12 through the first pipe 32, and is connected to the second inlet 24 through the second pipe 33, that is, the pipe box 31 is connected to the second mixing chamber 22 through the second pipe 33. In this way, the water supplied in the first mixing chamber 12 can flow into the pipe box 31 through the first pipe 32 and into the second mixing chamber 22 through the second pipe 33, thereby realizing the series connection between the first material box 1 and the second material box 2.

[0065] In some implementations, reference Figure 1 , Figure 2 , Figures 5 to 8 As shown, in a preset direction, both the first tube 32 and the second tube 33 can be disposed between the first material box 1 and the second material box 2, and this disclosure does not limit this.

[0066] In some embodiments, the preset direction can be left-right, and the connecting structure 3 and the negative pressure compensation structure 7 can be positioned close to the front side of the first material box 1 and the front side of the second material box 2. This allows the connecting structure 3 and the negative pressure compensation structure 7 to be positioned forward, facilitating the series connection between the first material box 1 and the second material box 2. The connecting portion 311 of the aforementioned tube box 31 can be connected to the front crossbeam of the housing; this disclosure does not impose any limitations on this.

[0067] In some implementations, the negative pressure compensation structure 7 can be constructed in any suitable manner, referencing Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the negative pressure compensation structure 7 may include a compensation element 71, which includes a compensation cavity 711 containing a compensation gas. The compensation cavity 711 is connected to the connecting structure 3. In other words, the negative pressure compensation structure 7 can pre-fill the compensation cavity 711 of the compensation element 71 with compensation gas. Because the compensation cavity 711 is connected to the connecting structure 3, when liquid rapidly flows out of the first mixing cavity 12, the water hammer effect generated in the first mixing cavity 12 will cause the compensation gas in the compensation cavity 711 to automatically flow into the connecting structure 3 and then automatically be added to the first mixing cavity 12. Similarly, when liquid rapidly flows out of the second mixing cavity 22, the water hammer effect generated in the second mixing cavity 22 will cause the compensation gas in the compensation cavity 711 to automatically flow into the connecting structure 3 and then automatically be added to the second mixing cavity 22. This further improves the reliability of the dispensing device.

[0068] In addition, when the water supply and washing liquid flow into the first mixing chamber 12, the compensation gas introduced into the first mixing chamber 12 can at least partially return to the compensation chamber 711. Thus, when the liquid in the first mixing chamber 12 flows out of the first mixing chamber 12 quickly again, the compensation gas in the compensation chamber 711 will automatically flow back into the first mixing chamber 12. Therefore, the setting of the compensation chamber 711 can realize the cyclic compensation of the negative pressure in the first mixing chamber 12.

[0069] Similarly, when the water supply and washing liquid flow into the second mixing chamber 22, the compensation gas introduced into the second mixing chamber 22 can at least partially return to the compensation chamber 711. Thus, when the liquid in the second mixing chamber 22 flows out of the second mixing chamber 22 rapidly again, the compensation gas in the compensation chamber 711 will automatically flow back into the second mixing chamber 22. Therefore, the compensation chamber 711 can realize the cyclic compensation of the negative pressure in the second mixing chamber 22.

[0070] In some embodiments, reference Figure 5 and Figure 6 As shown, the compensation member 71 can be disposed on the outside of the connecting structure 3. This allows the space outside the connecting structure 3 to be used to arrange the compensation member 71, avoiding the compensation member 71 occupying the internal space of the connecting structure 3. The compensation member 71 can be disposed at any suitable location on the connecting structure 3, such as on the aforementioned pipe box 31; this disclosure does not impose any limitations on this.

[0071] In some implementations, reference Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the first material box 1 and the second material box 2 can be spaced apart in the left-right direction, and the compensation member 71 can be connected to the upper side of the connecting structure 3. In this way, the flow of liquid in the connecting structure 3 into the compensation cavity 711 can be reduced or even avoided.

[0072] In some implementations, reference Figure 5 As shown, the compensation component 71 has a first end 712 and a second end 713 arranged opposite to each other along its extension direction. Both the first end 712 and the second end 713 can have an opening 714, which connects the compensation cavity 711 and the connecting structure 3. The advantage of this arrangement is that when the compensation gas in the compensation cavity 711 compensates for the pressure in the connecting structure 3, the compensation gas can enter the connecting structure 3 through any one of the two openings 714. Thus, more openings 714 allow the compensation gas to enter the connecting structure 3 more quickly, and then quickly enter the first mixing cavity 12 and the second mixing cavity 22, thereby improving the negative pressure compensation effect.

[0073] In some implementation examples, refer to Figure 5 As shown, the compensation member 71 is constructed as a compensation tube, which can be constructed as a U-shaped tube. The two opposite ends of the U-shaped tube are constructed as a first end 712 and a second end 713. This arrangement facilitates the formation of an opening 714 at the first end 712 and an opening 714 at the second end 713 on the compensation tube. In addition, the U-shaped tube arrangement can reduce the length of the compensation member 71 between the two openings 714 without changing the volume of the compensation cavity 711, thereby reducing the space occupied by the compensation member 71 and facilitating its arrangement. Of course, in embodiments where both the first end 712 and the second end 713 include an opening 714, the compensation tube can also be constructed as a W-shaped tube, an M-shaped tube, etc. This disclosure does not impose too many restrictions on the specific shape of the compensation tube.

[0074] In some embodiments, the compensation tube can be constructed as a U-shaped flexible tube, and two connecting nozzles can be provided on the connecting structure 3. The first end 712 and the second end 713 can be respectively connected to a connecting nozzle, for example, sleeved on a connecting nozzle. This disclosure does not limit this.

[0075] In some implementations, reference Figure 6 As shown, the compensation member 71 has a first end 712 and a second end 713 arranged opposite each other along its extension direction. The first end 712 is closed, that is, it restricts the compensation gas in the compensation cavity 711 from flowing out of the compensation member 71 through the first end 712. The second end 713 has an opening 714, which connects the compensation cavity 711 and the connecting structure 3. In this way, the compensation gas in the compensation cavity 711 can flow into the connecting structure 3 through the opening 714, realizing the connection between the compensation cavity 711 and the connecting structure 3. In addition, the closure of the first end 712 can simplify the structure of the compensation member 71 and improve the reliability of the compensation member 71.

[0076] In some embodiments, where the first end 712 is closed, the compensation member 71 can be configured as a compensation tube, which can be a straight tube, for example, extending in a vertical direction. Of course, the compensation tube can also be configured as a bent tube, and this disclosure does not limit this.

[0077] In other embodiments, where the first end 712 is closed, the compensation member 71 can also be constructed in other non-tubular shapes. For example, the compensation member 71 can be constructed as a cylinder, a sphere, an ellipsoid, a polygonal prism, or a pyramid. Correspondingly, the shape of the compensation cavity 711 can also be constructed as a sphere, an ellipsoid, a pyramid, or a pyramid. Here, this disclosure does not impose excessive limitations on the specific shape of the compensation member 71.

[0078] In some embodiments of this disclosure, for water box 4, the outlet 41 of water box 4 can be directly connected to the first inlet 11 of the first material box 1, that is, the distance between the outlet 41 and the first inlet 11 is basically zero. Similarly, the return water outlet 42 of water box 4 can be directly connected to the second outlet 21 of the second material box 2, that is, the distance between the return water outlet 42 and the second outlet 21 is basically zero.

[0079] In some implementations, reference Figures 1 to 4 As shown, the outlet 41 of the water box 4 is connected to the upstream of the first water inlet 11 of the first material box 1 via the inlet pipe 81, and the return water outlet 42 of the water box 4 is connected to the downstream of the second water outlet 21 of the second material box 2 via the outlet pipe 82. Thus, by connecting the outlet 41 and the first water inlet 11 via the inlet pipe 81, the positions of the outlet 41 and the first water inlet 11 can be flexibly arranged. Similarly, by connecting the second water outlet 21 and the return water outlet 42 via the outlet pipe 82, the positions of the second water outlet 21 and the return water outlet 42 can be flexibly arranged. This facilitates the assembly of the dispensing device and the assembly with other components of the garment processing equipment, such as the housing.

[0080] In some implementations, reference Figure 1 and Figure 2 As shown, the first material box 1 and the second material box 2 are spaced apart along a preset direction, and at least part of the water box 4 is arranged between the first material box 1 and the second material box 2 in the preset direction. In this way, on the one hand, the arrangement space between the first material box 1 and the second material box 2 can be used to arrange the water box 4, thereby improving the utilization rate of the arrangement space in the garment processing equipment. On the other hand, this arrangement makes the water box 4 close to both the first material box 1 and the second material box 2. This makes the distance between the outlet 41 and the first water inlet 11 closer, thus facilitating the shortening of the length of the water inlet pipe 81, and the distance between the return water outlet 42 and the second water outlet 21 closer, thus facilitating the shortening of the length of the water outlet pipe 82. This makes it easier to quickly add washing liquid to the drum.

[0081] In some embodiments, the preset direction can be left and right, and the water box 4 is located behind the first material box 1 and the second material box 2. In this way, the water box 4 can supply water to the first material box 1 from back to front through the water inlet pipe 81. Since the garment processing equipment usually takes in water from the rear, the arrangement of the water box 4 can adapt to the water inlet of the garment processing equipment, thereby facilitating the dispensing device to dispense washing liquid.

[0082] In some implementations, reference Figure 1 and Figure 2As shown, the water inlet pipe 81 can extend in the front-to-back direction. The rear end of the water inlet pipe 81 is connected to the outlet 41, and the front end of the water inlet pipe 81 is connected to the first water inlet 11. In this way, the water inlet pipe 81 can transport the water supply from the outlet 41 to the first water inlet 11 from back to front, and then transport it to the first material box 1.

[0083] In some embodiments, reference Figure 1 and Figure 2 As shown, the water inlet pipe 81 may include a first section 811 and a second section 812. The first section 811 is connected to the outlet 41 and is positioned between the first material box 1 and the second material box 2 in the left-right direction. The second section 812 is connected to the first water inlet 11 and is positioned above the first material box 1. This allows the space between the first material box 1 and the second material box 2 to be used for the arrangement of the first section 811, facilitating a compact design of the dispensing device. Furthermore, the second section 812 is positioned above the first material box 1, meaning it is connected to the top of the first material box 1. This prevents the second section 812 from being positioned to the side or below the first material box 1, thus avoiding backflow of water into the second section 812 when the water supply exits the first material box 1.

[0084] In some implementations, reference Figure 1 and Figure 2 As shown, the water outlet pipe 82 can extend in a front-to-back direction. The front end of the water outlet pipe 82 is connected to the second water outlet 21, and the rear end of the water outlet pipe 82 is connected to the return water outlet 42. In this way, the water outlet pipe 82 can transport the water supply from the second water outlet 21 to the return water outlet 42 from front to back, thereby allowing the water supply mixed with washing liquid to flow back into the water box 4, which facilitates the addition of washing liquid into the drum by the water box 4.

[0085] In some embodiments, reference Figure 1 and Figure 2 As shown, the water outlet pipe 82 includes a third section 821 and a fourth section 822. The third section 821 can communicate with the outlet 41 and is positioned above the second material box 2. The fourth section 822 can communicate with the return water inlet 42 and is positioned between the first material box 1 and the second material box 2 in the left-right direction. This arrangement of the third section 821 above the second material box 2 avoids the situation where the third section 821 is positioned to the side or below the second material box 2, preventing water from flowing directly into the third section 821 when it flows into the first material box 1 through the connecting structure 3, thus preventing some water from being mixed with the washing liquid in the second material box 2. Furthermore, the space between the first material box 1 and the second material box 2 can be used to arrange the fourth section 822, facilitating a compact design of the dispensing device.

[0086] In some implementations, reference Figure 1 and Figure 2 As shown, the first material box 1 and the second material box 2 are spaced apart in the left-right direction. In the left-right direction, the connecting structure 3 can be set between the first material box 1 and the second material box 2, and is set close to the front side of the first material box 1 and the front side of the second material box 2. In this way, on the one hand, the space between the first material box 1 and the second material box 2 can be used to arrange the connecting structure 3, which is conducive to the compact design of the dispensing device. On the other hand, the connecting structure 3 can transfer the water supply in the first material box 1 to the second material box 2 from the front side of the dispensing device, thus avoiding the connecting structure 3 being placed at the rear and encroaching on the arrangement space of the water box 4.

[0087] In some implementations, see reference Figures 1 to 4 as well as Figure 7 and Figure 8 As shown, the water inlet 46 can be connected to a water supply pipe 83, which is used to connect to the drum of the laundry processing equipment. In this way, the washing liquid can be added to the drum using the water supply pipe 83.

[0088] At least one water inlet 46 may include a first water inlet 10, and at least one water supply pipe 83 may include a first water supply pipe 40. In the left-right direction, the first water supply pipe 40 is disposed between the first material box 1 and the second material box 2 and is used to communicate with the first cylinder 100 of the garment processing equipment. In this way, the first water supply pipe 40 can be arranged in the arrangement space between the first material box 1 and the second material box 2, which is conducive to the compact design of the dispensing device.

[0089] In some embodiments, reference Figures 1 to 4 as well as Figure 7 and Figure 8 As shown, the first water supply pipe 40 may include a first water supply section 401 and a second water supply section 402 connected to each other. The first water supply section 401 extends in a front-to-back direction, and its rear end is connected to the first water inlet 10. The second water supply section 402 extends in a vertical direction, and its lower end is connected to the first cylinder 100. In this way, the first water supply section 401 can transport water mixed with detergent from the water box 4 from back to front, and the second water supply section 402 can transport the water in the first water supply section 401 downward. This facilitates the forward and downward transportation of water, thereby facilitating the addition of detergent to the first cylinder 100 from the front and top.

[0090] In some embodiments, reference Figures 1 to 6As shown, the connecting structure 3 may include a pipe box 31, and the second water supply section 402 may be connected to the pipe box 31. The pipe box 31 is used to connect to the housing of the clothing processing equipment. In this way, the pipe box 31 can provide auxiliary support for the second water supply section 402, thereby ensuring the reliability of the second water supply section 402. The second water supply section 402 may be integrally formed into the pipe box 31; this disclosure does not impose any limitations on this.

[0091] In some embodiments, reference Figure 5 and Figure 6 As shown, the second water supply section 402 can be arranged below the aforementioned negative pressure compensation structure 7, and this disclosure does not impose any restrictions on this arrangement. Additionally, the second water supply section 402 can be arranged below the aforementioned first pipe 32, and this disclosure also does not impose any restrictions on this arrangement.

[0092] In some implementations, reference Figures 1 to 6 As shown, the water box 4 may have a first side 43 and a second side 44 arranged opposite to each other along a preset direction. The first side 43 is close to the first material box 1, and the second side 44 is close to the second material box 2. The first side 43 is provided with a first water inlet 10, and the first water supply pipe 40 is arranged close to the first material box 1. In this way, it is convenient to transport water forward from the first side 43, and arranging the first water supply pipe 40 relatively close to the first material box 1 can reduce the bending of the first water supply pipe 40 and facilitate the delivery of water by the first water supply pipe 40.

[0093] In some embodiments, the first water supply section 401 may be arranged above the first section 811 to make full use of the vertical arrangement space near the first material box 1. This disclosure does not limit this.

[0094] In some implementations, reference Figures 1 to 4 as well as Figure 7 and Figure 8 As shown, at least one water inlet 46 includes a second water inlet 20, and at least one water supply pipe 83 includes a second water supply pipe 50. The rear end of the second water supply pipe 50 is connected to the second water inlet 20, and the front end of the second water supply pipe 50 is used to connect to the second drum 200 of the laundry processing equipment. This facilitates the delivery of water from back to front to the front of the second drum 200 through the second water supply pipe 50, so as to realize the dispensing of washing liquid into the second drum 200.

[0095] In some implementations, reference Figures 1 to 4 as well as Figure 7 and Figure 8As shown, at least one water inlet 46 includes a third water inlet 30, and at least one water supply pipe 83 includes a third water supply pipe 60. The rear end of the third water supply pipe 60 is connected to the third water inlet 30, and the front end of the third water supply pipe 60 is used to connect to the third drum 300 of the laundry processing equipment. This facilitates the delivery of water from back to front to the front of the third drum 300 through the third water supply pipe 60, so as to realize the dispensing of washing liquid into the third drum 300.

[0096] In some embodiments, reference Figures 1 to 4 as well as Figure 7 and Figure 8 As shown, both the second water inlet 20 and the third water inlet 30 may include a main inlet 461, and both the second water supply pipe 50 and the third water supply pipe 60 include a main pipe 831 connected to the corresponding main inlet 461.

[0097] In this configuration, the front end of the main pipe 831 of the second water supply pipe 50 is closer to the first feed box 1 than its rear end; similarly, the front end of the main pipe 831 of the third water supply pipe 60 is closer to the second feed box 2 than its rear end. Thus, at least a portion of the second water supply pipe 50 is inclined from back to front, towards the first feed box 1. This arrangement facilitates the dispensing of washing liquid from the front of the second feed box 200 into the second feed box 200 when the first feed box 1 and the second drum 200 are located on the same side. Similarly, at least a portion of the third water supply pipe 60 is inclined from back to front, towards the second feed box 2. This arrangement facilitates the dispensing of washing liquid from the front of the third feed box 300 into the third feed box 300 when the second feed box 2 and the third drum 300 are located on the same side.

[0098] In some embodiments, reference Figures 1 to 4 as well as Figure 7 and Figure 8 As shown, both the second water inlet 20 and the third water inlet 30 can include a defoaming port 462, and both the second water supply pipe 50 and the third water supply pipe 60 include a defoaming pipe 832 connected to the corresponding defoaming port 462. Thus, the defoaming pipe 832 can assist in supplying water to the corresponding second cylinder 200 or third cylinder 300 to quickly eliminate foam within the second cylinder 200 or third cylinder 300.

[0099] In some implementations, reference Figures 1 to 4 As shown, the reversing valve 6 can be located on the rear side of the water box 4. In this way, the arrangement space on the rear side of the water box 4 can be used to arrange the reversing valve 6, thereby facilitating the arrangement of the water supply port 46 on the front side of the water box 4.

[0100] In some implementations, reference Figures 1 to 4As shown, the water inlet valve 5 can be located at the rear of the water box 4. This allows the water inlet valve 5 to supply external water into the water box 4 from the rear to the front.

[0101] In some implementations, reference Figures 1 to 4 As shown, the outlet 41, return water inlet 42 and supply water inlet 46 can all be arranged on the front side of the water box 4.

[0102] Below, this disclosure will provide a detailed description of the specific flow direction of the water in the dispensing device, in conjunction with the above-described specific embodiments. (Reference) Figures 1 to 4 As shown, after receiving external water supply, the water inlet valve 5 can pump the water from the outside into the water box 4 from back to front, specifically into the water inlet chamber 45 of the water box 4. Subsequently, the water in the water inlet chamber 45 can flow into the water inlet pipe 81 through the outlet 41, and then flow from back to front along the water inlet pipe 81, and flow into the first material box 1 through the first water inlet 11. Afterwards, the water supply mixes with the detergent in the first material box 1. The mixed water can flow into the connecting structure 3, so that the water supply flows in the left and right direction in the connecting structure 3. When the first material box 1 is located on the left side of the second material box 2, the water supply flows from left to right in the connecting structure 3 and flows into the second material box 2. Then, the mixed water supply can mix with the detergent in the second material box 2. Subsequently, the water supply mixed with the detergent in the first material box 1 and the detergent in the second material box 2 can flow out of the second material box 2 through the second water outlet 21 and flow into the water outlet pipe 82. Then, the water supply flows from front to back along the water outlet pipe 82 and flows into the water box 4 through the return water outlet 42, specifically, into the return water chamber 47.

[0103] Subsequently, the water supply in the return water chamber 47 enters the reversing valve 6. The reversing valve 6 can then, as needed, release the water mixed with washing liquid into the corresponding water supply chamber 48. The water mixed with washing liquid in the water supply chamber 48 can then flow out through the water supply port 46 and be released into the corresponding cylinder. Specifically, the water supplied into the first water supply pipe 40 can flow from back to front and then from top to bottom, so as to enter the first cylinder 100 through the front and top sides. The water supplied into the second water supply pipe 50 can flow from back to front and towards the first material box 1, so as to enter the second cylinder 200 through the front side. The water supplied into the third water supply pipe 60 can flow from back to front and towards the second material box 2, so as to enter the third cylinder 300 through the front side.

[0104] According to a second aspect of this disclosure, a garment processing apparatus is provided, including the dispensing device described above. This garment processing apparatus possesses all the beneficial effects of the dispensing device described above, which will not be elaborated upon herein.

[0105] In some embodiments of this disclosure, reference is made to Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the garment processing device may include a first cylinder 100 and a second cylinder 200, with the second cylinder 200 and the dispensing device disposed above the first cylinder 100; in the vertical direction, the first material box 1, the second material box 2, and the connecting structure 3 may be disposed between the first cylinder 100 and the second cylinder 200.

[0106] Through the above technical solution, in the garment processing equipment provided in this disclosure, the dispensing device can utilize the space between the first drum 100 and the second drum 200 to arrange the first material box 1, the second material box 2, and the connecting structure 3. This allows for the installation of the first material box 1, the second material box 2, and the connecting structure 3, thus achieving a reasonable arrangement of components. Furthermore, it facilitates ensuring the volume of the first material box 1 and the second material box 2, preventing insufficient dispensing of washing liquid due to excessively small volumes.

[0107] In some implementations, reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the water box 4 can be located behind the second cylinder 200. This allows the space behind the second cylinder 200 to be used to arrange the water box 4, thus facilitating full utilization of the space.

[0108] In some embodiments, reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the garment processing device may include a third cylinder 300, and the water box 4 may also be disposed behind the third cylinder 300.

[0109] In some implementations, reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the first water supply pipe 40 can be located above the first cylinder 100. In this way, on the one hand, the arrangement space above the first cylinder 100 can be used to arrange the first water supply pipe 40, and on the other hand, the first water supply pipe 40 can deliver washing liquid to the first cylinder 100 from top to bottom, avoiding backflow of water from the first cylinder 100 into the first water supply pipe 40 when the first water supply pipe 40 is arranged to the side or below the first cylinder 100.

[0110] In some implementations, reference Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the garment processing equipment includes a third drum 300, which is positioned above the first drum 100. A first detergent dispenser 1, a second detergent dispenser 2, and a connecting structure 3 are also disposed between the first drum 100 and the third drum 300. In this way, the garment processing equipment can achieve three-drum partitioned washing. Furthermore, the space between the first drum 100 and the third drum 300 can be used to arrange the first detergent dispenser 1, the second detergent dispenser 2, and the connecting structure 3, ensuring sufficient volume for both dispensers and avoiding insufficient detergent due to small size.

[0111] In some embodiments, the second water inlet 20 and the third water inlet 30 both include a main inlet 461, and the second water supply pipe 50 and the third water supply pipe 60 both include a main pipe 831 connected to the corresponding main inlet 461. The main pipe 831 can dispense washing liquid into the second cylinder 200 or the third cylinder 300.

[0112] Among them, reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the main pipe 831 may include a main section 8311, which extends vertically, and the highest point of the main section 8311 is higher than the highest points of the second cylinder 200 and the third cylinder 300. Here, since the space between the second cylinder 200 and the first cylinder 100 is used to arrange the first material box 1, the second material box 2, and the connecting structure 3, it is inconvenient for the main pipe 831 to extend from between the second cylinder 200 and the first cylinder 100, or from between the third cylinder 300 and the first cylinder 100. Therefore, by setting the main section 8311 of the main pipe 831 to extend upward to a point higher than the highest point of the second cylinder 200 and the third cylinder 300, it is convenient to arrange the part of the main pipe 831 connected to the main section 8311 above the second cylinder 200 or the third cylinder 300, for example, to facilitate the arrangement of the auxiliary section 8312 and the connecting section 8313 described below.

[0113] In some embodiments, reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the main pipe 831 may include an auxiliary section 8312 connected downstream of the main section 8311. The auxiliary section 8312 extends in a front-rear direction and is disposed between the second cylinder 200 and the third cylinder 300. In this way, on the one hand, the auxiliary section 8312 is disposed above the second cylinder 200 or the third cylinder 300, and on the other hand, the auxiliary section extends forward to facilitate connection to the front side of the second cylinder 200 or the front side of the third cylinder 300.

[0114] In some embodiments, reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the main pipe 831 may include a connecting section 8313 downstream of the auxiliary section 8312. The connecting section 8313 of the second water supply pipe 50 extends obliquely downwards towards the side closer to the second cylinder 200; the connecting section 8313 of the third water supply pipe 60 extends obliquely downwards towards the side closer to the third cylinder 300. In this way, the connecting pipe of the second water supply pipe 50 can realize the connection between the second water supply pipe 50 and the second cylinder 200, and the connecting pipe of the third water supply pipe 60 can realize the connection between the third water supply pipe 60 and the third cylinder 300.

[0115] In some implementations, reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the defoaming port 462 can be connected to a defoaming tube 832, which extends in the vertical direction. This facilitates the use of vertical space to arrange the defoaming tube 832.

[0116] The following will describe in detail the specific water supply path of water supply pipe 83. Specifically, for the first water supply pipe 40, the water supplied can first be conveyed from back to front along the first water supply section 401. Then, the water entering the second water supply section 402 can be conveyed downwards, thereby dispensing the washing liquid from the front and top of the first cylinder 100 into the first cylinder 100. The water supplied by the second water supply pipe 50 can first be conveyed upwards along the main section 8311, then forwards along the auxiliary section 8312, and then leftwards and downwards along the connecting section 8313, thereby dispensing the washing liquid into the second cylinder 200. Similarly, the water supplied by the third water supply pipe 60 can first be conveyed upwards along the main section 8311, then forwards along the auxiliary section 8312, and then rightwards and downwards along the connecting section 8313, thereby dispensing the washing liquid into the third cylinder 300.

[0117] In some implementations, reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the water inlet pipe 81 can be located below the second cylinder 200, and the water outlet pipe 82 can be located below the third cylinder 300. This facilitates the use of the space between the second cylinder 200 and the first material box 1 to arrange the water inlet pipe 81. Similarly, it facilitates the use of the space between the third cylinder 300 and the second material box 2 to arrange the water outlet pipe 82.

[0118] In some implementations, reference Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the first material box 1 and the second cylinder 200 are both located at the upper left of the first cylinder 100, and the second material box 2 and the third cylinder 300 are both located at the upper right of the first cylinder 100. This allows the first material box 1 and the second cylinder 200 to be positioned on the same side, and the second material box 2 and the third cylinder 300 to be positioned on the same side. The garment processing equipment includes a first cylinder 100, a second cylinder 200, and a third cylinder 300, with the second cylinder 200 positioned at the upper left of the first cylinder 100 and the third cylinder 300 positioned at the upper right of the first cylinder 100.

[0119] In some implementations, reference Figure 7 and Figure 8 As shown, the volume of the second tub 200 can be smaller than the volume of the first tub 100. Thus, the second tub 200 can be used to wash small or lightweight garments, while the first tub 100 can be used to wash large or heavy garments.

[0120] In some implementations, reference Figure 7 and Figure 8 As shown, the volume of the third tub 300 can be smaller than the volume of the first tub 100. Thus, the third tub 300 can be used to wash small or lightweight garments, while the first tub 100 can be used to wash large or heavy garments.

[0121] In some implementations, reference Figure 7 and Figure 8 As shown, the depth of the second cylinder 200 can be less than that of the first cylinder 100 so that the water box 4 can be arranged behind the second cylinder 200. Similarly, the depth of the third cylinder 300 can be less than that of the first cylinder 100 so that the water box 4 can be arranged behind the third cylinder 300.

[0122] In some implementations, reference Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, for the water box 4, a vent pipe 49 may be provided on the water box 4. The vent pipe 49 is used to communicate with the first cylinder 100 and to vent air into the first cylinder 100. This disclosure does not limit this.

[0123] In some implementations, reference Figure 7 and Figure 8As shown, a first counterweight 91 can be provided on the second cylinder 200, for example, the first counterweight 91 can be provided on the side of the second cylinder 200 near the third cylinder 300. Similarly, a second counterweight 92 can be provided on the third cylinder 300, for example, the second counterweight 92 can be provided on the side of the third cylinder 300 near the second cylinder 200. In this way, the first counterweight 91 can increase the weight of the second cylinder 200, thereby delaying the vibration of the second cylinder 200. Similarly, the second counterweight 92 can increase the weight of the third cylinder 300, thereby delaying the vibration of the third cylinder 300.

[0124] In some embodiments, reference Figure 7 and Figure 8 As shown, the auxiliary section 8312 of the second water supply pipe 50 can be located above the first counterweight 91, allowing the auxiliary section 8312 of the second water supply to avoid collision with the first counterweight 91. Similarly, the auxiliary section 8312 of the third water supply pipe 60 can be located above the second counterweight 92, allowing the auxiliary section 8312 of the third water supply to avoid collision with the second counterweight 92.

[0125] In some implementations, reference Figure 7 and Figure 8 As shown, a connector 93 can be connected between the second cylinder 200 and the third cylinder 300, so that the vibration of one of the second cylinder 200 and the third cylinder 300 can be transmitted to the other through the connector 93, so as to use the other for vibration reduction.

[0126] In some embodiments, reference Figure 7 and Figure 8 As shown, both the second cylinder 200 and the third cylinder 300 may include a front cylinder and a rear cylinder. The connector 93 may be integrally formed between the front cylinder of the second cylinder 200 and the front cylinder of the third cylinder 300. This disclosure does not limit this.

[0127] In some embodiments, reference Figure 7 and Figure 8 As shown, the connector 93 may include connected horizontal and vertical ribs. The horizontal ribs may be connected between the second cylinder 200 and the third cylinder 300. In this way, the connector 93 can have good structural strength, which is beneficial for transmitting vibration between the second cylinder 200 and the third cylinder 300.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
