Description

Technical Field

[0001] This utility model relates to a garment processing device, and more particularly to a multi-tube garment processing device. Background Technology

[0002] Existing multi-drum laundry handling devices include a housing and multiple independently operable washing drums housed within the housing, allowing users to wash different types of clothing separately. In the prior art, to reduce the number of drain outlets in the machine, the drain pipes of different washing drums are usually connected to the same drain box, and then discharged through a single drain outlet from the drain box.

[0003] For example, the drainage device disclosed in existing patent CN217052751U includes a drainage box and a drainage pipe. The drainage box has several drainage chambers and several water inlets, each drainage chamber communicating with one of the water inlets. The drainage box also has a drainage hole communicating with all the drainage chambers. The drainage pipe is installed at the end face of the drainage hole opening, and the drainage pipe has several first drainage channels, each first drainage channel communicating with one of the drainage chambers to form an independent flow channel. The drainage box includes a detachably connected box body and a box cover. The drainage chambers and water inlets are located in the box body, while the drainage holes are located on the box cover. Existing drain boxes are usually installed on the outside of the casing, and each drain pipe needs to be individually inserted through the casing to connect to each water inlet. As a result, the ends of multiple drain pipes connected to the water inlets are exposed on the outside of the casing, meaning that the outlet ends of multiple drain pipes are visible. This not only takes up too much space but also reduces the appearance of the product. In addition, the exposed outlet ends of the drain pipes are more susceptible to detachment due to external impacts, which can lead to leakage problems. Utility Model Content

[0004] To address the shortcomings and deficiencies of the existing technology, this utility model provides a multi-tube clothing processing device. By placing the water inlet seat inside the casing, it not only ensures the reliability of the connection between the drain pipe and the water inlet, but also reduces the volume of the drain box exposed outside the casing, thus avoiding excessive space occupation and improving the product's appearance.

[0005] To achieve the above-mentioned technical objectives, this utility model provides a multi-drum washing device, including a housing, a drain box, and at least two washing drums installed inside the housing. Each washing drum is connected to a drain pipe. The drain box includes a water inlet seat and a water outlet seat. The water inlet seat has at least two water inlets and a drain cavity communicating with each water inlet. Each water inlet is connected to a drain pipe. The water outlet seat has a drain port. The water inlet seat is located inside the housing, and the water outlet seat is located outside the housing. The housing has a through hole, and a connector is provided between the water inlet seat and the water outlet seat through the through hole. The connector connects the drain cavity and the drain port.

[0006] Preferably, the connector includes a first connector disposed on the water inlet seat and communicating with the drain cavity, and a second connector disposed on the water outlet seat and communicating with the drain outlet, wherein the first connector and the second connector are sleeved together to connect the drain cavity and the drain outlet.

[0007] Preferably, the first connector has a positioning section located on the outside of the housing, and the second connector is sleeved on the outside of the positioning section.

[0008] Preferably, the water inlet seat is further provided with a first connecting part, and the housing is provided with a support frame for supporting the washing drum. The first connecting part is connected to the support frame or to the washing drum so that the water inlet seat is pre-installed in the housing; or the first connecting part is connected to the housing so that the water inlet seat is pre-installed on the housing.

[0009] Preferably, the water inlet seat is provided with a second connecting part, the water outlet seat is provided with a third connecting part, and the fastener passes through the third connecting part and is detachably connected to the second connecting part.

[0010] Preferably, the projections of the second connecting portion and the third connecting portion on the housing are both located within the through hole, so that the second connecting portion and the third connecting portion abut against each other.

[0011] Preferably, the second connecting portion has a second abutting surface surrounding the outside of the connector, the third connecting portion has a third abutting surface abutting against the second abutting surface, and a sealing ring is sandwiched between the second abutting surface and the third abutting surface.

[0012] Preferably, the housing includes a detachably connected back plate, and the back plate is provided with the through hole.

[0013] Preferably, a sealing element is provided between the connector and the wall of the through hole to seal the gap between the connector and the wall of the through hole.

[0014] Preferably, the water inlet seat includes a top wall and a bottom wall, and the top wall and / or the bottom wall are provided with a vertically extending connecting pipe, the inside of the connecting pipe forming the water inlet; and / or the bottom of the water outlet seat is provided with a downwardly extending water outlet pipe, the inside of the water outlet pipe forming the drain outlet.

[0015] By adopting the above technical solution, this utility model has the following advantages:

[0016] 1. The water inlet seat of this utility model is located inside the housing, and the water outlet seat is located outside the housing. The housing is provided with a through hole, and a connector is provided between the water inlet seat and the water outlet seat through the through hole. The connector connects the drainage chamber and the drainage outlet. By placing the water inlet base inside the casing, the water inlet can be located inside the casing. This allows the drain pipe to be hidden inside the casing and connected to the water inlet, avoiding the unsightly appearance caused by the drain pipe being exposed outside the casing and the problem of the connection failing due to external impact. This ensures the reliability of the connection between the drain pipe and the water inlet, and reduces the volume of the drain box exposed outside the casing, with only the water outlet base exposed, thus avoiding excessive space occupation and improving the product's appearance. In addition, placing the water outlet base outside the casing facilitates connection to an external drainage system, and allows for direct external operation for drain blockage or cleaning without opening the casing. Finally, the connector design ensures the continuity and shortest possible drainage path inside and outside the casing, allowing water in the drainage chamber to flow quickly through the connector to the drain outlet and be discharged from the drain box, thereby accelerating the drainage speed and reducing residue.

[0017] 2. The connector includes a first connector located on the inlet seat and communicating with the drain chamber, and a second connector located on the outlet seat and communicating with the drain outlet. The first connector and the second connector are sleeved together to connect the drain chamber and the drain outlet. The sleeved connection increases the connection reliability and sealing reliability of the first connector and the second connector, effectively preventing connection failure or leakage. In addition, the sleeved connection of the first connector and the second connector also provides a pre-positioning effect for the subsequent outlet seat, thereby reducing the assembly difficulty of the outlet seat.

[0018] 3. The first connector has a positioning section located on the outside of the housing, and the second connector is sleeved on the outside of the positioning section. This design allows the positioning section to form a physical guiding structure. During installation, workers can directly insert the second connector along the positioning section, avoiding misalignment caused by blind operation and resulting in difficulty in smooth assembly.

[0019] 4. The water inlet base also has a first connecting part, and a support frame for supporting the washing drum is provided inside the housing. The first connecting part is connected to the support frame or to the washing drum so that the water inlet base is pre-installed inside the housing; or the first connecting part is connected to the housing so that the water inlet base is pre-installed on the housing. This design allows the support frame, washing drum, or housing to become the mounting carrier for the water inlet base. Since the support frame, washing drum, or housing are all existing structures, there is no need to add an additional bracket to fix the water inlet base, thereby simplifying the product structure. By pre-installing the water inlet base, the pre-positioning of the water inlet base can be achieved, which facilitates the subsequent connection between the water inlet base and the water outlet base, thereby reducing the assembly difficulty of the water inlet base and the water outlet base.

[0020] 5. The water inlet seat has a second connecting part, and the water outlet seat has a third connecting part. Fasteners pass through the third connecting part and are detachably connected to the second connecting part. This design allows the water outlet seat to be assembled after the casing is assembled. The fasteners pass through the third connecting part from the outside in and connect to the second connecting part, allowing for fastener assembly on the outside of the casing, thus reducing the difficulty of fastener assembly. Furthermore, the fastener connection between the water outlet seat and the water inlet seat further improves the reliability of their connection. Finally, during maintenance, only the fasteners need to be removed to separate the water outlet seat, while maintaining the connection between the water inlet seat and the inside of the casing, making maintenance simple and convenient.

[0021] 6. The projections of the second and third connecting parts on the housing are both located within the through holes, so that the second and third connecting parts abut against each other. Compared with the solution where the housing needs to make through holes for fasteners to pass through to cover the second connecting part, this technical solution only requires making the through holes larger to expose the second connecting part, thereby reducing the processing difficulty of the housing.

[0022] 7. The second connecting part has a second abutting surface surrounding the outside of the connector, and the third connecting part has a third abutting surface that abuts against the second abutting surface. A sealing ring is sandwiched between the second abutting surface and the third abutting surface. This design allows for circumferential compression of the sealing ring to prevent water leakage at the connection between the water outlet seat and the water inlet seat.

[0023] 8. The housing includes a detachable back panel with the aforementioned through-hole. This design allows the water outlet to be hidden at the rear of the product, preventing it from being observed by the user, thus improving the product's appearance; the detachable design of the back panel also facilitates the subsequent disassembly, maintenance, or replacement of the water inlet.

[0024] 9. A sealing element is provided between the connector and the wall of the through hole to seal the gap between them. This design prevents foreign objects from entering the housing through the through hole; in addition, the sealing element also has a shock-absorbing function, thus preventing the connector from colliding with the wall of the through hole due to vibration during use and generating noise.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the terms "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," etc., which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0039] Example 1

[0040] Combination Figures 1 to 11 As shown, the multi-drum clothing processing device of this utility model includes a housing, a drain box 100, and at least two washing drums installed inside the housing. Each washing drum is used for washing clothes. The washing drum can be a drum type or a pulsator type. Multiple washing drums can be stacked or placed side by side, which is not limited here. Each washing drum is connected to a drain pipe. The water from multiple drain pipes is discharged uniformly through the drain box 100. In this embodiment, the drain box 100 includes a water inlet seat 110 and a water outlet seat 120. The water inlet seat 110 has at least two water inlets 111 and a drain cavity communicating with each water inlet 111. Each water inlet 111 is connected to a drain pipe. The water outlet seat 120 has a drain outlet 121. The water inlet seat 110 is located inside the housing, and the water outlet seat 120 is located outside the housing. The housing has a through hole 200. A connector 130 is provided between the water inlet seat 110 and the water outlet seat 120 through the through hole 200. The connector 130 connects the drain cavity and the drain outlet 121.

[0041] In this embodiment, by placing the water inlet base 110 inside the casing, the water inlet 111 can be located inside the casing. This allows the drain pipe to be hidden inside the casing and connected to the water inlet 111 located inside the casing, avoiding the unsightly appearance caused by the drain pipe being exposed outside the casing and the problem of the connection failing due to external impact. This ensures the reliability of the connection between the drain pipe and the water inlet 111 and reduces the volume of the drain box 100 exposed outside the casing, with only the water outlet base 120 exposed, thus avoiding excessive space occupation and improving the appearance of the product. In addition, placing the water outlet base 120 outside the casing facilitates connection of the water outlet base 120 to an external drainage system, and allows for direct operation outside the machine to handle blockages or cleaning of the drain outlet 121 without opening the casing. Finally, the design of the connector 130 ensures the continuity and shortest possible drainage path inside and outside the casing, allowing water in the drainage chamber to flow quickly through the connector 130 to the drain outlet to be discharged from the drain box 100, thereby accelerating the drainage speed and reducing residue.

[0042] Specifically, in this embodiment, the connector 130 includes a first connector 131 and a second connector 132. Both the first connector 131 and the second connector 132 are hollow structures, so that water passages are formed inside the first connector 131 and the second connector 132. The first connector 131 is disposed on the water inlet seat 110 and the water passage inside the first connector 131 is connected to the drain cavity. The second connector 132 is disposed on the water outlet seat 120 and the water passage inside the second connector 132 is connected to the drain outlet 121. The first connector 131 and the second connector 132 are sleeved together to connect the drain cavity and the drain outlet 121. That is, the first connector 131 is sleeved on the outside of the second connector 132 or the second connector 132 is sleeved on the outside of the first connector 131. The sleeved method can increase the connection reliability and sealing reliability of the first connector 131 and the second connector 132, effectively avoiding connection failure or leakage. In addition, the sleeved connection of the first connector 131 and the second connector 132 also provides a pre-positioning effect for the subsequent water outlet seat 120, thereby reducing the assembly difficulty of the water outlet seat 120.

[0043] In this embodiment, the first connector 131 and the water inlet seat 110 are integrally injection molded, and the second connector 132 and the water outlet seat 120 are integrally injection molded. The water inlet end of the water passage in the first connector 131 is connected to the water outlet of the drain chamber. The second connector 132 is sleeved on the outside of the first connector 131 so that the water outlet end of the water passage in the first connector 131 is connected to the second connector 132. In this way, the assembly steps of the first connector 131 and the water inlet seat 110 and the sealing structure between them can be eliminated, as well as the assembly steps of the second connector 132 and the water outlet seat 120 and the sealing structure between them can be eliminated, reducing the assembly steps while effectively preventing water leakage.

[0044] Taking a multi-drum laundry handling device with three washing drums as an example, there are also three corresponding water inlets 111. The three water inlets 111 are connected to the three washing drums one by one through three drain pipes. The water inlet base 110 includes a top wall and a bottom wall. A total of three vertically extending connecting pipes are provided on the top wall and / or the bottom wall. The water inlet 111 is formed inside the connecting pipe. Preferably, some connecting pipes are located on the top wall and some connecting pipes are located on the bottom wall. This can avoid the large volume of the water inlet base 110 caused by all of them being concentrated on the top wall or the bottom wall. The bottom of the water outlet base 120 is provided with a downwardly extending water outlet pipe. The drain outlet 121 is formed inside the water outlet pipe so that the water in the water outlet base 120 can be discharged in time through the drain outlet 121 under the action of gravity.

[0045] Taking a system with three water inlets 111 as an example, the drainage chamber in this embodiment includes three drainage channels, namely the first drainage channel 01, the second drainage channel 02, and the third drainage channel 03, as follows: Figures 4 to 6As shown, for ease of description, the three inlets 111 are defined as the first inlet 111a, the second inlet 111b, and the third inlet 111c. The first inlet 111a is connected to the first drainage channel 01, the second inlet 111b is connected to the second drainage channel 02, and the third inlet 111c is connected to the third drainage channel 03. The internal water passage of the first connector 131 includes a first water passage 131a and a second water passage 131c that are separated and independent from each other. The first drainage channel 01 is connected to the first water passage 131a, and the second drainage channel 02 is connected to the first drainage channel 03. Water channel 01 is connected so that water in the second drainage channel 02 flows through the first drainage channel 01 to the first water passage 131a. The third drainage channel 03 is set independently and is not connected to the first drainage channel 01 or the second drainage channel 02. The third drainage channel 03 is connected to the second water passage 131c so that water in the third drainage channel 03 flows to the second water passage 131c. The water passage inside the second connector 132 is connected to both the first water passage 131a and the second water passage 131c so that water flows through the second connector 132 to the water outlet seat 120 and is discharged from the drain outlet 121. With this design, when water enters the inlet seat 110 through the first inlet 111a and the second inlet 111b, it can be discharged to the outlet seat 120 through the first water passage 131a, preventing it from flowing into the third drainage passage 03 and then into the drain pipe connected to the third inlet 111c, thus preventing cross-contamination. Since the first inlet 111a and the second inlet 111b are both located on the top wall of the inlet seat, the outlet end of the drain pipe connected to the first inlet 111a and the second inlet 111b is higher than the second drainage passage 02 and the first drainage passage 01. Therefore, the connection between the second drainage passage 02 and the first drainage passage 01 will not cause cross-contamination between the two drain pipes.

[0046] It is understood that in other embodiments of this utility model, when there are two washing tubs, there are also two water inlets. One water inlet is located on the top wall of the water inlet base, and the other water inlet is located on the bottom wall of the water inlet base. In this case, the drainage channels connected to the two water inlets are distributed vertically and separated to prevent cross-contamination of water.

[0047] like Figure 9 As shown, in this embodiment, the first connector 131 is provided through the through hole 200 and has a positioning section 1310 located on the outside of the housing, and the second connector 132 is sleeved on the outside of the positioning section 1310. This design allows the positioning section 1310 to form a physical guiding structure. During installation, the worker can directly insert the second connector 132 along the positioning section 1310, avoiding misalignment caused by blind operation and thus preventing smooth assembly.

[0048] In addition, the water inlet seat 110 in this embodiment is also provided with a first connecting part 112, which is a mounting ear. A support frame for supporting the washing drum is provided inside the housing. The first connecting part 112 is connected to the support frame by screws or to the washing drum by screws so that the water inlet seat 110 is pre-installed in the housing; or the first connecting part 112 is connected to the housing by screws so that the water inlet seat 110 is pre-installed on the housing. This design allows the support frame, washing drum, or housing to serve as the mounting carrier for the water inlet base 110. Since the support frame, washing drum, or housing are all existing structures, there is no need to add an additional bracket to fix the water inlet base 110, thus simplifying the product structure. By pre-installing the water inlet base 110, its pre-positioning can be achieved, which facilitates the subsequent connection between the water inlet base 110 and the water outlet base 120, thereby reducing the assembly difficulty of the water inlet base 110 and the water outlet base 120. Finally, fixing the water inlet base 110 with screws also allows for detachable installation of the water inlet base 110, making it convenient for later disassembly, maintenance, and replacement.

[0049] Secondly, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 11 As shown, the water inlet seat 110 is also provided with a second connecting part 113, and the second connecting part 113 is provided with a threaded hole 1131. The water outlet seat 120 is provided with a third connecting part 122, and the third connecting part 122 is provided with a mounting hole 1221. Fasteners (screws) pass through the mounting hole 1221 of the third connecting part 122 and are detachably connected to the threaded hole 1131 on the second connecting part 113. With this design, the water outlet seat 120 can be assembled after the casing is assembled. The fasteners pass through the third connecting part 122 from the outside to the inside and are connected to the second connecting part 113, so that the fasteners can be assembled on the outside of the casing, thereby reducing the assembly difficulty of the fasteners. In addition, the fasteners can also be used to connect the water outlet seat 120 and the water inlet seat 110, thereby further improving the connection reliability between the water inlet seat 110 and the water outlet seat 120. Finally, during maintenance, only the fasteners need to be removed to separate the water outlet seat 120, while the water inlet seat 110 remains connected to the inside of the casing, making maintenance simple and convenient.

[0050] like Figure 8 As shown, preferably, the housing includes a left side panel, a right side panel, a top panel, a bottom panel, a front panel, and a back panel 300. The back panel 300 is detachably connected to the left side panel, right side panel, top panel, and bottom panel by screws. The back panel 300 has a through hole 200 running through the front and back. This design allows the water outlet 120 to be hidden at the rear of the product, preventing it from being seen by the user, thereby improving the product's appearance. The detachable design of the back panel 300 also facilitates the subsequent disassembly, maintenance, or replacement of the water inlet 110.

[0051] like Figure 11As shown, the projections of the second connecting portion 113 and the third connecting portion 122 on the back plate 300 are both located within the through hole 200, so that the second connecting portion 113 and the third connecting portion 122 abut against each other. Compared with the solution where the back plate needs to make a through hole for fasteners to pass through to cover the second connecting portion 113, this technical solution only requires making the through hole 200 larger to expose the second connecting portion 113, thereby reducing the number of holes to be processed on the back plate 300 and reducing the processing difficulty of the back plate 300.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 11 As shown, to prevent water leakage between the second connecting part 113 and the third connecting part 122, in this embodiment, the second connecting part 113 is an annular rib that surrounds the outside of the first connector 131 and is spaced apart from the first connector 131. The end face of the second connecting part 113 forms a second abutting surface 1132 that surrounds the outside of the first connector 131. A plurality of threaded holes 1131 are circumferentially spaced on the second abutting surface 1132. The third connecting part 122 is an annular rib that protrudes from the outside of the second connector 132. A mounting hole 1221 is provided on the third connecting part 122. One end of the third connecting part 122 facing the water inlet seat 110 forms a third abutting surface 1222 that abuts against the second abutting surface 1132. The end of the second connector 132 is inserted between the second connecting part 113 and the first connector 131 so that the second connector 132 is fitted onto the outside of the first connector 131. A sealing ring is sandwiched between the second abutting surface 1132 and the third abutting surface 1222. This design allows for circumferential compression of the sealing ring to prevent leakage at the connection between the water outlet seat 120 and the water inlet seat 110.

[0053] Finally, a sealing element is provided between the connector 130 and the wall of the through hole 200, that is, a sealing element is provided between the second connector 132 and the wall of the through hole 200 to seal the gap between the second connector 132 and the wall of the through hole 200. This design can prevent foreign objects from entering the housing through the through hole 200; in addition, the sealing element can also have a shock absorption function, thus preventing the connector 130 from colliding with the wall of the through hole 200 due to vibration during use and generating noise.

[0054] It is understood that in other embodiments of this utility model, one of the left side plate and the right side plate of the housing is provided with the above-mentioned through hole so that the connector passes through the left side plate or the right side plate.

[0055] It is understood that in other embodiments of this utility model, the number of connectors is one, one of the water inlet seat and the water outlet seat is integrally formed with the connector, and the other is provided with a mounting hole for the connector to be inserted, so that the connector connects the drain chamber and the drain outlet.

[0056] It is understood that in other embodiments of this utility model, after the second connector on the water outlet seat is sleeved on the first connector, the water outlet seat can also be fixedly connected to the back plate by screws to maintain the sleeved state of the second connector and the first connector and prevent the two from separating.

[0057] In addition to the preferred embodiments described above, there are other embodiments of this utility model. Those skilled in the art can make various changes and modifications based on this utility model. As long as they do not depart from the spirit of this utility model, they should all fall within the scope defined in the claims of this utility model.
