[0019] In some embodiments, the garment handling device includes a second tubular assembly, which includes a second tubular body and a second vent pipe.

[0020] The second cylinder is provided with a second vent, one end of the second vent pipe is connected to the second vent, and the other end is connected to the atmosphere.

[0021] In some embodiments, the garment processing device includes a second tubular assembly and a water collector. The second tubular assembly includes a second tubular body and a second drain pipe. The water collector is provided with a water collection chamber and an outlet, a second inlet, and at least one first inlet all connected to the water collection chamber. The first drain pipe is connected to the first inlet, and the second drain pipe is connected to the second inlet.

[0022] In some embodiments, the number of first cylinder assemblies is at least two, the number of first inlets is at least two, each first inlet is connected to a corresponding first cylinder, and the liquid in each first cylinder is discharged into the water collection chamber through the corresponding first inlet.

[0023] In some embodiments, there are at least two first drain pipes, one of which is located on the left or right side of the second cylinder, with one end of the first drain pipe connected to one of the first inlets in a front-back direction and the other end connected to one of the first cylinders; the other first drain pipe is located on the rear side of the first cylinder, with one end of the first drain pipe connected to another first inlet in a left-right direction and the other end connected to another first cylinder.

One end of the first vent pipe is connected to a first vent, and the other end is connected to the atmosphere. During liquid inlet or outlet of the first cylinder, the first vent pipe maintains pressure balance within the cylinder, ensuring smooth liquid inlet or outlet. Furthermore, since the first vent pipe connects the first cylinder to the first drain pipe, when there is excessive liquid or air bubbles within the first cylinder, some of the liquid or air bubbles can overflow through the first vent pipe to the first drain pipe and be discharged. In addition, because the first vent pipe connects the first cylinder to the atmosphere, it also helps prevent siphoning during the draining process to some extent. In other words, the first vent pipe in this embodiment connects the first cylinder, the first drain pipe, and the atmosphere. Liquid and foam coming out of the first vent flow into the first vent pipe. The liquid will flow through the first vent pipe to the first drain pipe, while the foam, being lighter, will flow to the end of the first vent pipe closer to the atmosphere. This further facilitates drainage and can balance the air pressure inside the first cylinder and achieve overflow. While improving the reliability of the garment processing equipment, it further reduces the number of pipes required. Attached Figure Description

[0051] The following is a detailed description of this application.

[0052] This application provides a garment processing device.

[0053] It is understandable that garment processing equipment can come in various forms, such as washing machines, spin dryers, dryers, washer-dryer combos, and washer-dryer sets. Garment processing equipment can independently perform any one or more of the functions of washing, drying, and spin-drying.

[0054] Please see Figures 1 to 5 The garment processing equipment includes at least one first cylinder assembly 20. The first cylinder assembly 20 includes a first cylinder 21, a first drain pipe 22, and a first vent pipe 23. The first cylinder 21 is provided with a first drain port 211 and a first vent port 212. The first drain pipe 22 is connected to the first drain port 211 and is used to drain liquid from the first cylinder 21. The first vent pipe 23 is connected to the first drain pipe 22, with one end connected to the first vent port 212 and the other end connected to the atmosphere.

[0055] For example, the garment handling equipment includes a housing, and a first cylinder 21 is disposed in the housing.

[0056] For example, the water collector 30 has a water collection cavity, and the water collector 30 has an outlet 33, a second inlet 31 and at least one first inlet 32 ​​that are all connected to the water collection cavity.

[0057] The end of the first drain pipe 22 away from the first drain port 211 is connected to the first inlet 32.

[0058] For example, the garment processing device includes a second cylinder assembly 10, which includes a second cylinder 11 and a second drain pipe 12. The second cylinder 11 is disposed in the housing and has a second drain port. One end of the second drain pipe 12 is connected to the second drain port and the other end is connected to the second inlet 31.

[0059] For example, the first vent pipe 23 includes a first connection port 234, a second connection port 235 and a third connection port 236 that are interconnected. The first connection port 234 is connected to the first vent port 212, the second connection port 235 is connected to the second drain pipe 12 and the third connection port 236 is connected to the atmosphere.

[0060] Understandably, the housing is used to provide accommodating space for the second cylindrical assembly 10 and the first cylindrical assembly 20, and the housing has sufficient structural strength to serve as a load-bearing component, vertically bearing weight and resisting horizontal forces. The first cylindrical assembly 20 is supported on the housing, and the housing is capable of bearing at least the weight of the first cylindrical assembly 20 and its load.

[0061] It is understood that the specific structure of the second cylinder 11 is not limited. The second cylinder 11 may include a first outer cylinder and a first inner cylinder. The first outer cylinder is fitted over the first inner cylinder. The first outer cylinder is used to hold water, and the first inner cylinder is used to hold clothing. In this embodiment, the first inner cylinder holds water through the first outer cylinder, and the first inner cylinder may also be referred to as a perforated inner cylinder. In other embodiments, the first inner cylinder holds water on its own, and may also be referred to as a non-perforated inner cylinder.

[0062] It is understood that the specific structure of the first cylinder 21 is not limited. The first cylinder 21 may include a second outer cylinder and a second inner cylinder. The second outer cylinder is fitted over the second inner cylinder. The second outer cylinder is used to hold water, and the second inner cylinder is used to hold clothing. In this embodiment, the second inner cylinder holds water through the second outer cylinder, and the second inner cylinder may also be referred to as a perforated inner cylinder. In other embodiments, the second inner cylinder holds water on its own, and may also be referred to as a non-perforated inner cylinder.

[0063] It is understood that the second drum assembly 10 and the first drum assembly 20 can be used to perform the same clothing processing function or different clothing processing functions. Exemplarily, in some embodiments, the second drum assembly 10 and the first drum assembly 20 can be used to wash or dry the same type of clothing or to wash or dry different types of clothing. For example, the second drum assembly 10 can wash or dry underwear, socks, etc., while the first drum assembly 20 can wash or dry outerwear, etc., thus allowing for corresponding washing or drying of clothing of different sizes or with different washing or drying requirements, thereby increasing clothing processing efficiency and reliability. In other embodiments, one of the second drum assembly 10 and the first drum assembly 20 is used for washing clothing, and the other is used for drying clothing, thus providing multiple clothing processing functions.

[0064] It should be noted that the second cylinder assembly 10 and the first cylinder assembly 20 can work simultaneously or separately.

[0065] Please see Figures 1 to 3 The first tubular body 21 is located above the second tubular body 11. "Above" means that the axis of the first tubular body 21 is higher than the axis of the second tubular body 11. The first tubular body 21 can be located directly above, to the upper left of, or to the upper right of the second tubular body 11, etc. This increases garment handling capacity without increasing floor space and facilitates the independent operation of the second tubular body assembly 10 and the first tubular body assembly 20, or their sequential operation to achieve different functions.

[0066] Please see Figure 1 The liquid in the second cylinder 11 can flow through the second drain pipe 12 and the second inlet 31 to the water collection chamber. The liquid in the first cylinder 21 can flow through the first drain pipe 22 and the first inlet 32 ​​to the water collection chamber, and then be discharged from the water collection chamber through the outlet 33.

[0067] For example, please refer to Figure 1 The second inlet 31 and the first inlet 32 ​​are positioned higher than the outlet 33. This allows the liquid flowing into the water collection chamber through the second inlet 31 and the first inlet 32 ​​to be directly discharged out of the water collector 30 through the lower outlet 33.

[0068] For example, the first vent 212 is located above the first drain port 211.

[0069] For example, the first vent 212 is located at the top of the first cylinder 21.

[0070] Here, the top of the first cylinder 21 refers to the portion located above the second reference surface of the first cylinder 21, where the second reference surface is a horizontal plane passing through the axis of the first cylinder 21. For example... Figure 3As shown, the second reference plane is denoted by M.

[0071] For example, the first vent 212 is positioned above the highest washing water level, so that liquid or foam in the outer tub that is above the highest washing water level can flow out to the water collection chamber through the first vent pipe 23, avoiding the problem of excessive water in the first tub 21 causing water overflow in the clothing processing equipment.

[0072] For example, the third port 236 of the first vent pipe 23 is connected to the atmosphere. When liquid is being introduced into or discharged from the first cylinder 21, the first vent pipe 23 can maintain the air pressure balance inside the first cylinder 21 to achieve smooth liquid introduction or discharge. The first vent pipe 23 connects the first cylinder 21 to the water collection chamber. When there is too much liquid or air bubbles in the first cylinder 21, some of the liquid or air bubbles can overflow into the water collection chamber through the first vent pipe 23 and be discharged away.

[0073] For example, when the second cylinder 11 is draining liquid, it can be connected to the atmosphere through the first vent pipe 23, which can also prevent the formation of a siphon effect during the draining process to a certain extent.

[0074] For example, when the first cylinder 21 is draining liquid, it can be connected to the atmosphere through the first vent pipe 23, which can also prevent the formation of a siphon effect during the draining process to a certain extent.

[0075] In addition, when the first cylinder 21 is draining liquid, or when a pressure difference is formed, it can avoid siphoning the liquid in the second cylinder 11 to a certain extent.

[0076] By setting up a water collector 30, the drained liquid from the second cylinder assembly 10 and the first cylinder assembly 20 can flow into the water collection chamber of the water collector 30, and then be discharged through the water outlet pipe 60 of the clothing processing equipment. This reduces the number of water outlet pipes 60, facilitates the internal piping of the clothing processing equipment, saves installation space, and thus helps to improve the structural compactness of the clothing processing equipment and reduce the space occupied by the clothing processing equipment.

[0077] In the garment processing device provided in this embodiment, the first cylinder assembly 20 is equipped with a first vent pipe 23, which is connected to a first drain pipe 22. One end of the first vent pipe 23 is connected to a first vent, and the other end is connected to the atmosphere. When liquid is being introduced into or discharged from the first cylinder 21, the first vent pipe 23 can maintain the air pressure balance inside the first cylinder 21, thus achieving smooth liquid introduction or discharge. Furthermore, since the first vent pipe 23 connects the first cylinder 21 to the first drain pipe 22, when there is excessive liquid or air bubbles inside the first cylinder 21, some of the liquid or air bubbles can overflow through the first vent pipe 23 to the first drain pipe 22 and be discharged. In addition, because the first vent pipe 23 connects the first cylinder 21 to the atmosphere, it can also prevent the formation of a siphon effect during the discharge process to a certain extent. In other words, the first vent pipe 23 in this embodiment connects the first cylinder 21, the first drain pipe 22, and the atmosphere. Liquid and foam coming out of the first vent 212 flow into the first vent pipe 23. The liquid will flow through the first vent pipe 23 to the first drain pipe 22. The foam is relatively light and will flow to the end of the first vent pipe 23 closer to the atmosphere. In this way, it is easier to drain the liquid and can balance the air pressure in the first cylinder 21 and the overflow effect. While improving the reliability of the clothing processing equipment, it further reduces the number of pipes.

[0078] In some embodiments, please refer to Figures 1 to 3 The garment processing equipment includes an atmospheric connector 50, and a first vent pipe 23 is connected to the atmospheric connector 50.

[0079] For example, the atmospheric connector 50 is disposed in the housing, that is, the atmospheric connector 50 is fixedly installed through the housing to improve the installation stability of the atmospheric connector 50.

[0080] In addition, when there is too much liquid or air bubbles in the first cylinder 21, some of the liquid or air bubbles can overflow to the atmospheric connection 50 through the first vent pipe 23.

[0081] Here, by setting up an atmospheric connector 50 and connecting the third connecting port 236 to the atmospheric connector 50, stable ventilation to the first cylinder assembly 20 can be achieved.

[0082] By incorporating an atmospheric connector 50, the second cylinder 11 can be connected to the atmospheric connector 50 via the second vent pipe 13, and the first cylinder 21 can be connected to the atmospheric connector 50 via the first vent pipe 23. This design balances the air pressure within both the second and first cylinders 11 and facilitates overflow. The atmospheric connector 50 also simplifies the piping arrangement of the garment processing equipment, saves installation space, and reduces costs. Furthermore, the connection of both the second vent pipe 13 and the first vent pipe 23 to the atmospheric connector 50 contributes to a more compact and streamlined design for the garment processing equipment.

[0083] In some embodiments, the interior of the atmospheric connector 50 contains a defoamer.

[0084] Here, by containing defoamer inside the atmospheric connector 50, foam overflowing into the atmospheric connector 50 can be eliminated, which can prevent foam from entering the atmosphere through the atmospheric connector 50 to a certain extent, thus improving the user experience.

[0085] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 The first cylinder assembly 20 includes a drain valve 24, and the second drain pipe 12 includes a first sub-drain pipe 221 and a second sub-drain pipe 222. The drain valve 24 is used to selectively connect the first sub-drain pipe 221 and the second sub-drain pipe 222. The end of the first sub-drain pipe 221 away from the drain valve 24 is connected to the first drain port 211.

[0086] For example, the first vent pipe 23 is connected to the second sub-drain pipe 222.

[0087] For example, the first vent pipe 23 is connected to the drain valve 24.

[0088] For example, the end of the second sub-drain pipe 222 away from the drain valve 24 is connected to the first inlet 32.

[0089] In other words, the first vent pipe 23 is connected to the second sub-drain pipe 222 and is connected to the water collector 30 through the second sub-drain pipe 222. The first vent pipe 23 is always connected to the water collection chamber of the water collector 30. That is, the drain valve 24 is used to selectively connect the first sub-drain pipe 221 and the second sub-drain pipe 222. The drain valve 24 cannot block the first vent pipe 23 from the water collection chamber.

[0090] Thus, even when the first drum 21 is not draining, liquid or foam above the highest washing water level inside the first drum 21 can overflow into the water collection chamber through the first vent pipe 23. Furthermore, the first vent pipe 23 is connected to the second sub-drain pipe 222 and, through the second sub-drain pipe 222, is connected to the water collector 30. This helps to shorten the length of the first vent pipe 23, facilitating pipe routing inside the garment processing equipment, saving installation space, and reducing costs.

[0091] For example, in some embodiments, the first sub-drain pipe 221 and the second sub-drain pipe 222 can be an integral structure, that is, the first sub-drain pipe 221 and the second sub-drain pipe 222 are the same pipe. In other embodiments, the first sub-drain pipe 221 and the second sub-drain pipe 222 can be a separate structure, which facilitates the drain valve 24 to selectively open or close the first sub-drain pipe 221 and the second sub-drain pipe 222.

[0092] In some embodiments, please refer to Figure 1 and Figure 2 The water collector 30 is positioned lower than the first cylinder 21 so that the water discharged from the first cylinder 21 can flow to the water collector 30 under the action of gravity.

[0093] In this way, the higher position of the first cylinder 21 compared to the water collector 30 can be used to achieve a "downward drainage" method, which is convenient for drainage. In addition, it can also improve the problem of liquid backflow from the water collector 30 to the first cylinder 21, and the water collector 30 does not need to be equipped with a backflow structure, which is conducive to further simplifying the drainage structure of the clothing processing equipment.

[0094] It should be noted that the specific structure of the first ventilator 23 is not limited here.

[0095] For example, in some embodiments, please refer to Figure 1 and Figure 5 The first ventilation tube 23 includes a first sub-tube 231, a second sub-tube 232 and a third sub-tube 233.

[0096] The first ends of the first sub-tube 231, the second sub-tube 232 and the third sub-tube 233 are interconnected. The second end of the first sub-tube 231 is connected to the first vent. The second end of the second sub-tube 232 is connected to the drain valve 24. The second end of the third sub-tube 233 is connected to the atmosphere.

[0097] For example, in some embodiments, the first sub-tube 231 and the second sub-tube 232 may be an integral venting pipe, and the third sub-tube 233 may be connected to the integral venting pipe; in other embodiments, the first sub-tube 231 and the third sub-tube 233 may be an integral venting pipe, and the second sub-tube 232 may be connected to the integral venting pipe; in still other embodiments, the second sub-tube 232 and the third sub-tube 233 may be an integral venting pipe, and the first sub-tube 231 may be connected to the integral venting pipe.

[0098] Here, the first sub-pipe 231 can be used for both overflow and ventilation. That is, when there is too much liquid or air bubbles in the first cylinder assembly 20, it can be discharged into the water collection chamber through the first sub-pipe 231 and the second sub-pipe 232 in sequence. The first cylinder assembly 20 can also be connected to the atmospheric connector 50 through the first sub-pipe 231 and the third sub-pipe 233 in sequence. This simplifies the piping layout while taking into account both overflow and venting.

[0099] For example, in some embodiments, please refer to Figure 1 and Figure 5The first vent tube 23 includes a first sub-tube 231, a second sub-tube 232, a third sub-tube 233, and a multi-port tube 237. One end of the first sub-tube 231 is connected to the multi-port tube 237, and the other end has a first connection port 234. One end of the second sub-tube 232 is connected to the multi-port tube 237, and the other end has a second connection port 235. One end of the third sub-tube 233 is connected to the multi-port tube 237, and the other end has a third connection port 236.

[0100] That is, one end of the first sub-tube 231, the second sub-tube 232 and the third sub-tube 233 are connected by a multi-port pipe 237, and the other end forms the first connecting port 234, the second connecting port 235 and the third connecting port 236 respectively.

[0101] For example, the second sub-tube 232 extends generally along the height direction so that the lower end of the second sub-tube 232 forms a second communication port 235 and is connected to the second sub-drainage pipe 222, and the upper end of the second sub-tube 232 is connected to the multi-port pipe 237.

[0102] Here, the first sub-pipe 231, the second sub-pipe 232 and the third sub-pipe 233 are connected by a multi-port pipe 237, which facilitates the molding and manufacturing of the first vent pipe 23.

[0103] For example, the junction of the first sub-tube 231 and the third sub-tube 233 is lower than the first communication port 234 and lower than the end of the third sub-tube 233 that is away from the first sub-tube 231.

[0104] Therefore, the liquid and foam coming out of the first vent 212 flow through the first sub-pipe 231 to the junction of the first sub-pipe 231, the second sub-pipe 232 and the third sub-pipe 233. Under the action of gravity, the liquid will flow down through the second sub-pipe 232 to the first drain pipe 22. The foam is relatively light and will flow through the end of the third sub-pipe 233 that is closer to the atmosphere (atmosphere connector 50). In this way, the situation of liquid entering the third sub-pipe 233 can be improved, and the drainage can be further facilitated.

[0105] For example, the second sub-tube 232 extends along the height direction of the garment handling device, a portion of the first sub-tube extends downward and communicates with the first end of the second sub-tube 232, and a portion of the third sub-tube extends downward and communicates with the first end of the second sub-tube 232.

[0106] In other words, the junction of the first sub-tube 231, the second sub-tube 232 and the third sub-tube 233 is roughly Y-shaped.

[0107] The first sub-tube 231 may extend downwards from the first end to facilitate the flow of liquid into the second sub-tube 232 under the action of gravity.

[0108] The third sub-tube 233 can extend downward from the first end, which reduces the flow of liquid into the third sub-tube 233 while allowing foam to enter the third sub-tube 233.

[0109] In other embodiments, the first vent tube 23 may also include only the first sub-tube 231, the second sub-tube 232, and the third sub-tube 233, without including the multi-port tube 237, that is, the first sub-tube 231, the second sub-tube 232, and the third sub-tube 233 are directly connected.

[0110] In some embodiments, the first vent pipe 23 includes a first sub-pipe 231 and a third sub-pipe 233. One end of the first sub-pipe 231 is connected to the first vent, and the other end is connected to the first drain pipe 22. One end of the third sub-pipe 233 is connected to the first sub-pipe 231, and the other end is connected to the atmosphere.

[0111] Here, the first sub-pipe 231 can be used for both overflow and ventilation. That is, when there is too much liquid or air bubbles in the first cylinder assembly 20, it can be discharged sequentially through the first sub-pipe 231 to the first drain pipe 22 and then discharged. The first cylinder assembly 20 can also be connected to the atmospheric connector 50 sequentially through the first sub-pipe 231 and the third sub-pipe 233. This simplifies the piping layout while taking into account both overflow and venting.

[0112] It should be noted that there are multiple ways to connect the first sub-tube 231 and the third sub-tube 233.

[0113] In some embodiments, the first vent tube 23 includes a multi-port tube 237, and the third sub-tube 233 is connected to the first sub-tube 231 through the multi-port tube 237.

[0114] Here, the first sub-pipe 231 and the third sub-pipe 233 are connected by a multi-port pipe 237, which facilitates the molding and manufacturing of the first vent pipe 23.

[0115] In other embodiments, an opening may be made directly on the first sub-tube 231 and then connected to the third sub-tube 233.

[0116] In some embodiments, the multi-port pipe 237 is connected to the drain valve 24.

[0117] In other words, the multi-port pipe 237 is connected to the drain valve 24 and is connected to the first drain pipe 22 through the drain valve 24.

[0118] When there is excessive liquid or air bubbles inside the first cylindrical assembly 20, it can be discharged sequentially through the first sub-pipe 231 and the multi-port pipe 237 to the first drain pipe 22 and then discharged. The first cylindrical assembly 20 can also be connected to the atmospheric connection member 50 sequentially through the first sub-pipe 231 and the third sub-pipe 233. This simplifies piping while balancing overflow and venting. For some embodiments, please refer to... Figure 1 and Figure 5 The positions of the first connecting port 234 and the third connecting port 236 are both higher than the position of the second connecting port 235.

[0119] For example, the positions of the first connecting port 234 and the third connecting port 236 are both higher than the position of the multi-port 237.

[0120] The position of the first connecting port 234 is higher than that of the second connecting port 235, so that when there is too much liquid or air bubbles in the first cylinder assembly 20, some of the liquid or air bubbles can overflow into the water collection chamber under the action of gravity.

[0121] The third connecting port 236 is positioned higher than the second connecting port 235. This allows air to enter the first connecting port 234 through the third connecting port 236 and flow to the first cylinder assembly 20. At the same time, it reduces the possibility of liquid in the first drain pipe 22 flowing to the third connecting port 236 through the second connecting port 235 when the first cylinder assembly 20 is draining liquid.

[0122] In some embodiments, please refer to Figures 1 to 3 The second cylinder 11 is provided with a second vent 111, and the second cylinder assembly 10 also includes a second vent pipe 13. One end of the second vent pipe 13 is connected to the second vent 111, and the other end is connected to the atmosphere.

[0123] For example, the second vent 111 is located above the second drain port.

[0124] For example, the second vent 111 is located at the top of the second cylinder 11.

[0125] Here, the top of the second cylinder 11 refers to the portion located above the first reference surface of the second cylinder 11, where the first reference surface is a horizontal plane passing through the axis of the second cylinder 11. For example... Figure 3 As shown, the first reference plane is denoted by N.

[0126] For example, the second vent 111 is positioned higher than the maximum washing water level. In this way, liquid or foam in the outer tub that is above the maximum washing water level can flow out to the water collection chamber through the second vent pipe 13, thus avoiding the problem of excessive water in the second tub 11 causing water overflow in the clothing processing equipment.

[0127] For example, one end of the second vent 13 away from the second vent 111 is connected to the atmospheric connector 50.

[0128] By providing a second vent pipe 13, which connects the second cylinder 11 to the atmosphere, the second vent pipe 13 can maintain the air pressure balance inside the second cylinder 11 during liquid inlet or outlet, thus ensuring smooth liquid inlet or outlet. Furthermore, when there is excessive liquid or air bubbles inside the second cylinder 11, some of the liquid or air bubbles can overflow to the atmosphere connector 50 through the second vent pipe 13.

[0129] In some embodiments, please refer to Figures 1 to 3 The number of first cylinder components 20 is at least two, the number of first inlets 32 is at least two, each first inlet 32 ​​is connected to a corresponding first cylinder 21, and the liquid in each first cylinder 21 is discharged into the water collection chamber through the corresponding first inlet 32.

[0130] In this embodiment, the number of first cylinder components 20 is two, that is, the garment processing device has at least three cylinder components, and one garment processing device can perform multiple different garment processing activities simultaneously or in sequence.

[0131] For example, the second tub assembly 10 can be used for washing outerwear, and the two first tub assemblies 20 can be used for washing underwear and socks, respectively.

[0132] In addition, the two first cylinders 21 can be located to the upper left and upper right of the second cylinder 11, respectively. That is, the two first cylinders 21 are arranged side by side and spaced apart in the left and right direction. This reduces interference and also reduces the size of the garment processing equipment in the height direction, which facilitates the overall balance of the garment processing equipment. The second cylinder 11 is located below the two first cylinders 21. The vertical stacking design reduces the lateral space of the garment processing equipment, thereby making the overall size of the garment processing equipment more suitable.

[0133] For example, two first inlets 32 are arranged at intervals along the height direction, with one first inlet 32 ​​positioned higher than the other first inlet 32, in order to reduce the interference between the two first inlets 32 when draining water.

[0134] In some embodiments, please refer to Figures 1 to 2 There are at least two first drain pipes 22. One first drain pipe 22 is located on the left or right side of the second cylinder 11, and one end of the first drain pipe 22 is connected to one of the first inlets 32 in the front-back direction, while the other end is connected to one of the first cylinders 21. The other first drain pipe 22 is located on the rear side of the first cylinder 21, and one end of the first drain pipe 22 is connected to another first inlet 32 ​​in the left-right direction, while the other end is connected to another first cylinder 21.

[0135] One of the first drain pipes 22 is located on the left or right side of the second cylinder 11 to guide the liquid discharged from the first cylinder 21 to a first inlet 32. This pipe arrangement utilizes the lateral space around the first cylinder 21, making the garment processing equipment compact.

[0136] Another first drain pipe 22 is located on the rear side of the first cylinder 21 to guide the liquid discharged from the first cylinder 21 to a first inlet 32. This pipe arrangement shortens the pipe length from the first cylinder 21 to the water collector 30, saving materials and installation space.

[0137] In some embodiments, please refer to Figures 1 to 3 The water collector 30 is located on the rear side of the second cylinder 11, and the outlet 33 is located on the rear side wall of the water collector 30.

[0138] In this way, the drainage point of the clothing processing equipment is located at the rear of the equipment, which makes it easier to connect to the drain pipes in the user's room, and it is also more concealed and aesthetically pleasing.

[0139] For example, the second cylinder assembly 10, the first cylinder assembly 20, and the water collector 30 are all disposed inside the tank.

[0140] The housing includes a back panel, and the garment processing equipment includes a water outlet pipe 60 and a pipe connector. The pipe connector passes through the back panel, and one end of the pipe connector is connected to the outlet 33 in the front-to-back direction. The water outlet pipe 60 is located outside the housing and is connected to the pipe connector.

[0141] It is understandable that the pipe joint draws out the liquid in the water collector 30 through the outlet 33 and discharges it through the outlet pipe 60.

[0142] In this embodiment, the pipe connector passes directly through the back panel, and the water outlet pipe 60 is located outside the housing, allowing the water collector 30 to be installed close to the inner surface of the back panel, reducing the space occupied on the rear side of the cylinder assembly, thus making the clothing processing equipment structure compact.

[0143] For example, please refer to Figure 6 As shown, the outlet 33 is located on the rear side wall of the water collector 30 to facilitate connection with the pipe fitting.

[0144] The structure of the pipe fitting is not limited; for example, the pipe fitting can be an elbow or a straight fitting.

[0145] Please see Figures 1 to 3 The following describes the direction of liquid flow within the water collector 30 in a specific embodiment of this application.

[0146] The liquid discharged from the second cylinder 11 enters the water collector 30 through the second inlet 31, and then enters the water outlet pipe 60 through the outlet 33 for discharge.

[0147] The liquid discharged from the first cylinder 21 at the upper left enters the water collector 30 through the lower first inlet 32, and then enters the water outlet pipe 60 through the outlet 33 for discharge.

[0148] The liquid discharged from the first cylinder 21 at the upper right enters the water collector 30 through the first inlet 32 ​​at a higher position, and then enters the water outlet pipe 60 through the outlet 33 for discharge.

[0149] In some embodiments, please refer to Figures 1 to 3 The volume of the second cylinder 11 is greater than the volume of the first cylinder 21.

[0150] For example, the second cylinder 11 has a first clothing processing cavity, and the first cylinder 21 has a second clothing processing cavity, the volume of the second clothing processing cavity being smaller than the volume of the first clothing processing cavity.

[0151] In other words, the second tube 11 can hold more clothes, meaning the overall weight of the second tube assembly 10 can be greater than that of the first tube assembly 20.

[0152] Thus, the second cylinder 11 can handle larger or larger quantities of clothing, such as outerwear, while the first cylinder 21 can handle smaller or smaller quantities of clothing, such as socks, underwear, or baby clothes.

[0153] In this embodiment, the volume of the second cylinder 11 is larger than that of the first cylinder 21. The second cylinder 11 located at the bottom is heavier, which makes it easier to lower the overall center of gravity of the clothing processing equipment. Thus, while increasing the stability of the clothing processing equipment, the second cylinder 11 can also offset the vibration from above based on its own weight, thereby increasing the overall balance performance of the clothing processing equipment.

[0154] In some embodiments, please refer to Figure 2 In the orthographic projection of the plane perpendicular to the height direction of the garment processing equipment, the two first cylinders 21 are arranged symmetrically with respect to the central axis of the second cylinder assembly 10.

[0155] In other words, when looking down along the height of the garment processing device, the two first cylinders 21 can be seen to be mirror-symmetrical about the central axis of the second cylinder assembly 10. That is, if the garment processing device is folded along the central axis of the second cylinder 11, the two first cylinders 21 can completely overlap.

[0156] In this embodiment, on the one hand, the symmetrical arrangement helps to make the entire garment processing equipment more stable during operation, and when one or both of the two first tubular components 20 work at the same time, the power of the two first tubular components 20 can be more balanced; on the other hand, the symmetrical arrangement can also make the layout more reasonable and increase the aesthetic appeal.

[0157] In some embodiments, please refer to Figures 1 to 3 The garment processing equipment includes a drain pump 40, which is installed in the second drain pipe 12 and is used to pump the liquid in the second drain pipe 12.

[0158] Under the action of the drain pump 40, the liquid discharged from the second cylinder 11 can overcome gravity and move upward. In other words, the second cylinder 11 can adopt the "upward drainage" drainage method, which is more efficient. Furthermore, due to the setting of the drain pump 40, backflow will basically not occur in the second cylinder assembly 10.

[0159] In some embodiments, please refer to Figure 2 Along the left and right direction of the garment processing equipment, the water collector 30 and the drain pump 40 are located on the same side of the vertical plane of the second cylinder 11, which is a vertical plane passing through the axis of the second cylinder 11.

[0160] For example, if the water collector 30 is located to the left of the vertical plane Q, then the drain pump 40 is also located to the left of the vertical plane Q; or, for example, if the water collector 30 is located to the right of the vertical plane Q, then the drain pump 40 is also located to the right of the vertical plane Q. Figure 2 As shown. This can shorten the pipe length between the second cylinder assembly 10 and the water collector 30, and also reduce the head loss of the drain pump 40.

[0161] For example, please refer to Figures 6 to 9 The atmospheric connector 50 is provided with a ventilation channel 51, a second connection port 52, and at least one first connection port 53, all of which are connected to the ventilation channel 51. One end of the second ventilation pipe 13 is connected to the second ventilation port 111, and the other end is connected to the second connection port 52. One end of the first ventilation pipe 23 is connected to the first ventilation port 212, and the other end is connected to the first connection port 53.

[0162] The atmospheric connector 50 facilitates the piping arrangement of the garment processing equipment, saves installation space, and reduces costs. Furthermore, both the second vent pipe 13 and the first vent pipe 23 are connected to the atmospheric connector 50, which helps to reduce the size and improve the compactness of the garment processing equipment.

[0163] In some embodiments, please refer to Figures 8 to 9 The lowest point of the first connection port 53 is higher than the highest point of the second connection port 52.

[0164] When there is too much liquid or air bubbles in the first cylinder 21, some of the liquid or air bubbles can overflow into the water collection chamber through the first vent pipe 23, and some of the liquid or air bubbles can also overflow into the ventilation channel 51 of the atmospheric connector 50 through the first vent pipe 23.

[0165] Since the lowest point of the first connection port 53 is set higher than the highest point of the second connection port 52, when some liquid or bubbles also overflow through the first vent pipe 23 to the venting channel 51 of the atmospheric connector 50, the liquid or bubbles can flow into the second cylinder 11 through the second connection port 52. This can, to a certain extent, improve the situation where the liquid or bubbles overflowing to the venting channel 51 directly overflow into the external environment through the third vent port 54 of the atmospheric connector 50, which is beneficial to improving the reliability of the overflow of the clothing treatment equipment and the user's experience.

[0166] In some embodiments, please refer to Figures 8 to 9 The lowest point of the second connection port 52 is not higher than the lowest point of the ventilation channel 51.

[0167] For example, the lowest point of the second connection port 52 is flush with the lowest point of the ventilation channel 51, or the lowest point of the second connection port 52 is lower than the lowest point of the ventilation channel 51.

[0168] Since the lowest point of the second connection port 52 is not higher than the lowest point of the ventilation channel 51, it is beneficial for the liquid or air bubbles overflowing into the ventilation channel 51 to flow back into the second cylinder 11 through the second connection port 52. This can improve the problem of water accumulation in the ventilation channel 51 and further improve the reliability of the clothing processing equipment and the user's experience.

[0169] In some embodiments, please refer to Figures 8 to 9 The atmospheric connector 50 is also provided with a third vent 54, through which the ventilation channel 51 is connected to the atmosphere. The lowest point of the third vent 54 is higher than the highest point of the first connector 53.

[0170] In other words, the second connection port 52 can be connected to the atmosphere through the third vent port 54, and the first connection port 53 can be connected to the atmosphere through the third vent port 54.

[0171] For example, if the lowest point of the third vent 54 is higher than the highest point of the first connection port 53, then the lowest point of the third vent 54 is also higher than the highest point of the second connection port 52.

[0172] Since the lowest point of the third vent 54 is higher than the highest point of the first connection port 53, it can improve the situation where liquid or bubbles overflowing into the ventilation channel 51 through the second connection port 52 and the first connection port 53 are directly discharged into the atmosphere through the third vent 54. It is also beneficial for all liquid or bubbles overflowing into the ventilation channel 51 to flow back into the second cylinder 11 through the second connection port 52.

[0173] It should be noted that the specific structure of the atmospheric connector 50 is not limited here.

[0174] In some embodiments, please refer to Figures 6 to 9 The atmospheric connector 50 includes a connecting body 55, the interior of which has a ventilation channel 51. A second connecting section 56 is provided at one end of the connecting body 55 along the axial direction. The second connecting section 56 has a second connecting port 52. At least one first connecting section 57 is provided on the circumferential sidewall of the connecting body 55. The first connecting section 57 has a first connecting port 53.

[0175] For example, the connecting body 55 may be columnar, with an internal ventilation channel 51 formed inside the column.

[0176] For example, in some embodiments, the cross-sectional shape of the connecting body 55 along the perpendicular axis can be circular, so that the liquid or bubbles overflowing into the ventilation channel 51 can flow back into the second cylinder 11 through the second connection port 52. Of course, in other embodiments, the cross-sectional shape of the connecting body 55 along the perpendicular axis can also be other shapes besides circular.

[0177] For example, the number of first connection ports 53 corresponds one-to-one with the number of first cylinders 21.

[0178] In an embodiment where there are two first connection ports 53, the two first connection ports 53 are symmetrically arranged about the vertical plane of the connecting body 55, which is a vertical plane passing through the axis of the connecting body 55.

[0179] For example, the cross-sectional area of ​​the second connecting segment 56 along the axial direction perpendicular to the second connecting segment 56 and the cross-sectional area of ​​the first connecting segment 57 along the axial direction perpendicular to the first connecting segment 57 are both smaller than the cross-sectional area of ​​the ventilation channel 51 along the axial direction perpendicular to the connecting body 55.

[0180] In some embodiments, please refer to Figures 6 to 7 An end plate 58 is provided at the end of the connecting body 55 away from the second connecting section 56. The end plate 58 forms a third vent 54, and the ventilation channel 51 is connected to the atmosphere through the third vent 54.

[0181] For example, the end plate 58 and the connecting body 55 can be an integral structure or a separate structure.

[0182] Here, the end plate 58 and the second connecting section 56 are respectively located at opposite ends of the connecting body 55 along the axial direction.

[0183] In this embodiment, an end plate 58 is provided at the end of the connecting body 55 away from the second connecting section 56, and the end plate 58 is formed with a third vent 54. While venting is carried out through the third vent 54, the end plate 58 can also block the liquid or bubbles overflowing into the ventilation channel 51, so that the liquid or bubbles overflowing into the ventilation channel 51 can flow back into the second cylinder 11 through the second connecting port 52.

[0184] In some embodiments, please refer to Figures 6 to 7 The end plate 58 is provided with a positioning post 581, which is positioned and cooperates with the housing.

[0185] The end plate 58 is provided with a positioning post 581, which is used to position and cooperate with the housing, thereby improving the reliability of the connection between the atmospheric connector 50 and the housing and the assembly efficiency.

[0186] The number of positioning posts 581 can be one or more.

[0187] For example, there are two positioning posts 581. The two positioning posts 581 can not only position the end plate 58, but also enable the atmospheric connector 50 to engage with the housing to prevent rotation.

[0188] In some embodiments, the end plate 58 is fastened to the housing.

[0189] For example, please refer to Figure 6 Both the end plate 58 and the housing are provided with fastening holes 582. Fasteners are inserted through the fastening holes 582 of the end plate 58 and the housing to achieve a fastening connection between the end plate 58 and the housing.

[0190] For example, the fastening connection between the end plate 58 and the housing includes, but is not limited to, bolt connection, screw connection, rivet connection, etc.

[0191] This connection method is simple and reliable.

[0192] For example, please refer to Figures 6 to 7 A portion of the end plate 58 on the side opposite to the connecting body 55 protrudes to form a protrusion 59, and a third vent 54 is formed on the protrusion 59. Thus, when the atmospheric connector 50 is installed in the housing, the protrusion 59 can be flush with the outer surface of the housing, or the protrusion 59 can protrude from the outer surface of the housing, which can improve the situation where the third vent 54 is blocked, thereby improving the reliability of ventilation of the clothing processing equipment.

[0193] For example, with the atmospheric connector 50 installed in the housing, the axis of the connecting body 55 is parallel to the horizontal plane, or the axis of the connecting body 55 is inclined upward. This is beneficial to further improve the situation where liquid or bubbles overflowing into the ventilation channel 51 are directly discharged into the atmosphere through the third vent 54.
