[0060] In this utility model, "front," "rear," "left," "right," "up," and "down" all refer to... Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The markings in the text shall prevail.

[0061] The following is based on Figures 1 to 11 This invention provides a detailed description of the garment processing equipment.

[0062] In this embodiment, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 and Figure 11 As shown, the garment processing equipment 100 includes a first outer tub 11, a first inner tub 12, a second outer tub 21, a second inner tub 22, a frame 71, and a housing 72. The frame 71 is located within the housing 72 and has a certain structural strength to form the supporting structure of the garment processing equipment 100. The housing 72 forms the outer contour structure of the garment processing equipment 100 and is typically a sheet metal structure. The first outer tub 11 accommodates the first inner tub 12, and the first outer tub 11 and the first inner tub 12 together constitute the first washing tub assembly 1. The second outer tub 21 accommodates the second inner tub 22, and the second outer tub 21 and the second inner tub 22 together constitute the second washing tub assembly 2.

[0063] like Figure 1 and Figure 2 As shown, the first outer tub 11 includes a first front tub 111 and a first rear tub 112, and the second outer tub 21 includes a second front tub 211 and a second rear tub 212. Figure 5As shown, the first front tub 111 and the second front tub 211 are integrally formed to form a front tub structure. In this solution, by configuring the front tubs of the first outer tub 11 and the second outer tub 21 as an integral unit, the overall structure becomes more stable. Furthermore, compared to the prior art solution of connecting each tub to the frame, the assembly of the first and second outer tubs in this solution is simpler to operate, involves fewer steps, and has higher space utilization. This is beneficial for the miniaturization design of the garment processing equipment 100, and thus facilitates the application of this solution in space-constrained scenarios where the garment processing equipment 100 has the function of processing multiple tubs separately.

[0064] In one implementation, such as Figure 6 As shown, the first rear tub 112 and the second rear tub 212 are integrally formed to form a rear tub structure. By configuring the rear tubs of the first outer tub 11 and the second outer tub 21 as an integral molding, the stability of the overall structure is further improved, the assembly operation and process of the first outer tub and the second outer tub are simplified, the space utilization rate is higher, and it is conducive to the miniaturization design of the garment processing equipment 100.

[0065] In one embodiment, the first inner tub 12 has a larger capacity and is used to handle large items of clothing (such as sweaters, coats, trousers, etc., which have a certain size and weight), while the second inner tub 22 has a smaller capacity and is used to sort and handle small items of clothing (such as underwear, baby clothes, socks, etc., which are small and lightweight), to facilitate the washing needs of multi-person households. Furthermore, the capacity of the first inner tub 12 can be more than 5 kg, and the capacity of the second inner tub 22 can be less than 3 kg.

[0066] In one implementation, such as Figure 1 and Figure 11 As shown, the first outer barrel 11 is fixed to the frame 71, the second front barrel 211 of the second outer barrel 21 is supported by the first front barrel 111 of the first outer barrel 11, and the second rear barrel 212 of the second outer barrel 21 is supported by the first rear barrel 112 of the first outer barrel 11. That is, the second outer barrel 21 is not directly connected to the frame 71, which can reduce the number of parts required for assembly, reduce the modification of the frame 71, and simplify the assembly process.

[0067] In one implementation, such as Figure 1As shown, the capacity of the second outer tub 21 is smaller than that of the first outer tub 11. There are two second outer tubs 21, which are located on either side of the top of the first outer tub 11. Each second outer tub 21 is matched with a second inner tub 22. Specifically, the first outer tub 11 is larger and heavier, and is located in the lower middle part of the casing 72, which helps to stabilize the center of gravity of the whole machine. Furthermore, the position of the first outer tub 11 can be the same as or approximately the same as the position of the outer tub in existing single-tub washing machines, so as to minimize the modification to the water circuit layout, wiring layout, and assembly structure related to the first outer tub 11, or even not modify them at all, utilizing the original water circuit, wiring, and assembly structure to reduce modification costs. Furthermore, the configuration of two second outer tubs 21 enriches the sorting and processing functions. For example, one second outer tub 21 can be dedicated to infant clothing, while the other can be dedicated to underwear. Moreover, this design places the two second outer tubs 21 on either side of the top of the first outer tub 11. This fully utilizes the existing space above the first outer tub 11, maximizing the installation space for the second outer tubs 21 and minimizing or even eliminating modifications to the overall machine dimensions, thus reducing processing costs. It also contributes to the stability of the machine's center of gravity. It should be understood that the number of second outer tubs 21 could also be three or even more, which would likely require increasing the size of the casing 72 to accommodate more second outer tubs 21.

[0068] Furthermore, such as Figure 1 and Figure 3 As shown, the two second outer tubs 21 are symmetrically arranged about the vertical plane of the central axis of the first outer tub 11, which can improve the dynamic balance of the garment processing equipment 100 and make the structure more stable. In addition, the two second outer tubs 21 are symmetrically arranged in appearance, which makes the garment processing equipment 100 more visually appealing.

[0069] Furthermore, such as Figure 1 and Figure 3 As shown, the central axes of the second outer barrel 21 and the first outer barrel 11 are parallel to each other. The plane in which the central axes of one second outer barrel 21 and the first outer barrel 11 lie is the first plane, and the plane in which the central axes of the other second outer barrel 21 and the first outer barrel 11 lie is the second plane. The angle between the first plane and the second plane is 55°-65°, preferably 60°. Specifically, one second outer barrel 21 is arranged as close as possible to the left side of the top of the first outer barrel 11 in the available space, and the other second outer barrel 21 is arranged as close as possible to the right side of the top of the first outer barrel 11 in the available space. In this way, the arrangement of the two second outer barrels 21 can make full use of the original available space between the top of the first outer barrel 11 and the left and right inner walls of the frame 71, and avoid the configuration of the second outer barrels 21 from increasing the overall height of the machine, or even adding two second outer barrels 21 within the original height of a single barrel.

[0070] In one implementation, such as Figure 1 and Figure 2 As shown, the axial depth of the first front bucket 111 is greater than the axial depth of the first rear bucket 112, and the axial depth of the second front bucket 211 is greater than the axial depth of the second rear bucket 212. Specifically, the first rear bucket 112 and the second rear bucket 212 need to be assembled with corresponding motors. The structures of the first rear bucket 112 and the second rear bucket 212 are more complex than those of the corresponding first front bucket 111 and the second front bucket 211. Therefore, the processing molds matched with the first rear bucket 112 and the second rear bucket 212 are more complex than those matched with the first front bucket 111 and the second front bucket 211. Setting the axial depth of the first front bucket 111 and the second front bucket 211 to be deeper than that of the corresponding rear bucket can reduce the processing difficulty and processing cost.

[0071] Furthermore, such as Figure 1 , Figure 4 and Figure 8 As shown, the first front barrel 111 and the second front barrel 211 are connected by a connecting rib 3, the length of which extends along the axial direction of the second front barrel 211. Specifically, since the axial depth of the first front barrel 111 and the second front barrel 211 is relatively large, in order to improve the stability of the connection between the two, a connecting rib 3 extending along the axial direction of the second front barrel 211 is configured. This allows the first front barrel 111 and the second front barrel 211 to be stably connected, and the connection structure is simple and easy to process.

[0072] Furthermore, such as Figure 1 and Figure 8 As shown, the connecting rib 3 extends from the front end face of the second front barrel 211 to the rear end face of the second front barrel 211. On the one hand, it can extend the extension length of the connecting rib 3 as much as possible to further improve the stability of the connection between the first front barrel 111 and the second front barrel 211. On the other hand, the front end face of the connecting rib 3 is coplanar with the front end face of the second front barrel 211, and the rear end face of the connecting rib 3 is coplanar with the rear end face of the second front barrel 211, which can reduce the probability of deformation of the front barrel structure during injection molding.

[0073] In one implementation, such as Figure 3 and Figure 4As shown, the capacity of the second outer tub 21 is smaller than that of the first outer tub 11. The second outer tub 21 is located above the first outer tub 11. The bottom wall of the second outer tub 211 extends downward to form a first extension 2111. A heating chamber 4 is formed between the inner wall of the first extension 2111 and the bottom outer wall of the second inner tub 22. The second inner tub 22 has multiple through holes (not shown in the figure), and the second inner tub 22 and the heating chamber 4 are connected through the through holes on the second inner tub 22. When the clothing processing equipment 100 starts the clothing processing program, the water in the water pipe in the housing 72 first enters the heating chamber 4, and then enters the second inner tub 22 through the heating chamber 4 to perform washing, rinsing, and dehydration operations on the clothes. Of course, tap water can also be directly sprayed into the second inner tub 22 through the spray device. The heating chamber 4 is used to house the heating element (not shown in the figure). When the second inner tub 22 needs to perform hot washing or sterilization treatment on the clothes, the heating element (e.g., heating tube) is turned on to heat the water in the heating chamber 4, so as to perform hot washing or sterilization treatment on the clothes in the second inner tub 22. In addition, the first extension 2111, the connecting rib 3 and the first front tub 111 are connected sequentially in the left-right direction of the clothes processing equipment 100, and the second outer tub 21 is arranged compactly with the first outer tub 11.

[0074] Furthermore, such as Figure 4 As shown, the first extension 2111 includes a first extension segment 21111, a second extension segment 21112, and a third extension segment 21113 connected sequentially in a direction away from the first front tub 111. The connecting rib 3 is connected to the first extension segment 21111 and the first front tub 111, respectively. The first extension segment 21111 is tangent to the circumference of the outer wall of the second front tub 211, which helps to increase the size of the heating chamber 4. This increases the volume of water that the heating chamber 4 can hold, thereby improving the washing effect. It also increases the installation space for the heating element, thereby improving the heating efficiency.

[0075] The maximum distance between the outer contour of the connection between the first front barrel 111 and the connecting rib 3 and the first extension section 21111 is S1, and the minimum distance between the circumference of the arc outer wall of the second front barrel 211 and the first front barrel 111 is S2, where S1 < S2. The connecting rib 3 is connected to the first extension section 21111 and the first front barrel 111 respectively. Specifically, if the connecting rib 3 is directly connected to the circumferential arc surface of the first front barrel 111 and the circumferential outer wall of the second front barrel 211 respectively, the wall thickness of the connecting rib 3 at various parts along the circumferential direction of the first front barrel 111 will vary greatly. This will cause the connecting rib 3 to easily deform during the integral injection molding process of the first front barrel 111 and the second front barrel 211, resulting in an increased product defect rate. Therefore, in this solution, the first extension section 21111 is configured to be tangent to the circumference of the outer wall of the second front barrel 211, and S1 < S2 is limited. The connecting rib 3 is connected to the first extension section 21111 and the first front barrel 111 respectively. By optimizing the setting position of the connecting rib 3, the wall thickness of the connecting rib 3 at various parts along the circumferential direction of the first front barrel 111 is made as equal as possible or the difference is small, so as to reduce the product defect rate. It should be understood that the distance between the outer contour of the connection between the first front bucket 111 and the connecting rib 3 and the first extension segment 21111 refers to the vertical distance between any point on the outer contour of the connection between the first front bucket 111 and the connecting rib 3 and the first extension segment 21111. Since the outer contour of the connection between the first front bucket 111 and the connecting rib 3 is arc-shaped, the vertical distance between any point on this arc and the first extension segment 21111 varies. The maximum distance S1 is the largest of these vertical distances. The minimum distance S2 between the circumference of the arc-shaped outer wall of the second front bucket 211 and the first front bucket 111 refers to the smallest distance between any point on the arc-shaped outer wall of the second front bucket 211 and any point on the first front bucket 111.

[0076] Furthermore, such as Figure 4 As shown, the second extension section 21112 extends horizontally, reducing the presence of dead corners in the bottom cavity wall of the heating cavity 4, thereby reducing the probability of stains remaining in the heating cavity 4.

[0077] Specifically, as Figure 3 and Figure 4The following is a detailed description using the garment processing device 100 shown as an example. Regarding the second outer tub 21 located on the upper left side of the first outer tub 11, the second front tub 211 of this second outer tub 21 has a first extension 2111, which includes a first extension segment 21111, a second extension segment 21112, and a third extension segment 21113 connected sequentially from right to left. The first extension segment 21111 is tangent to the circumference of the outer wall of the second front tub 211, and the starting position of the first extension segment 21111 is defined such that S1 < S2. Regarding the second outer tub 21 located on the upper right side of the first outer tub 11, this second outer tub 21 and the second outer tub 21 located on the upper left side of the first outer tub 11 are symmetrically arranged about the vertical plane of the central axis of the first outer tub 11. The structure and location of the first extension 2111 and the connecting rib 3 related to this second outer tub 21 will not be described further.

[0078] In one implementation, such as Figure 6 and Figure 7 As shown, the bottom of the second rear bucket 212 is provided with a second extension 2121. The second extension 2121 has the same or approximately the same structure as the first extension 2111. The inner wall of the second extension 2121 forms part of the cavity wall of the heating chamber 4. The heating element is installed on the second rear bucket 212. The length of the heating element extends along the axial direction of the second outer bucket 21 to increase the heating surface area.

[0079] In one implementation, such as Figure 2 , Figure 6 and Figure 7 As shown, the first rear drum 112 and the second rear drum 212 are connected by a connecting plate 5, which extends in the vertical direction. Specifically, the first rear drum 112 and the second rear drum 212 are relatively short (small axial depth), and the space between them in the front-to-back direction is limited. By connecting them with the connecting plate 5 extending in the vertical direction, the first rear drum 112 and the second rear drum 212 can be connected as a whole, while also improving the stability of the connection, ensuring the stability of the whole machine operation, and extending the service life.

[0080] Furthermore, such as Figure 2 , Figure 6 and Figure 7As shown, the longitudinal section of the connecting plate 5 is approximately triangular. The connecting plate 5 includes a first sidewall 51, a second sidewall 52, and a third sidewall 53 connected sequentially. The first sidewall 51 extends along a portion of the circumferential surface wall of the first rear tub 112 and is integrally formed with the first rear tub 112. The second sidewall 52 extends along a portion of the circumferential surface wall of the second rear tub 212 and is integrally formed with the second rear tub 212. The third sidewall 53 extends vertically. By optimizing the structure of the connecting plate 5, the structural stability of the connecting plate 5 is improved, making the integral structure of the first rear tub 112 and the second rear tub 212 more stable. Of course, in one specific embodiment, the garment processing device 100 is equipped with two second outer tubs 21, and the two second outer tubs 21 are symmetrically arranged about the vertical plane of the central axis of the first outer tub 11. In order to improve the overall structural stability of the tub, the two connecting plates 5 are symmetrically arranged about the vertical plane of the central axis of the first outer tub 11, and are used to connect the second rear tubs 212 of the two second outer tubs 21 respectively.

[0081] Furthermore, the third sidewall 53 extends vertically to further improve the stability of the integral structure of the second rear barrel 212 and the first rear barrel 112.

[0082] In one implementation, such as Figure 5 As shown, the axial depth of the first front bucket 111 is equal to the axial depth of the second front bucket 211, so as to make full use of the circumferential space of the first front bucket 111 and maximize the capacity of the second outer bucket 21.

[0083] Furthermore, such as Figure 2 As shown, the capacity of the second outer tub 21 is smaller than that of the first outer tub 11. The second outer tub 21 is located above the first outer tub 11. The axial depth of the first rear tub 112 is greater than that of the second rear tub 212. The rear end face of the second rear tub 212 is located in front of the rear end face of the first rear tub 112. Specifically, components such as a water inlet valve and a drying air duct (not shown in the figure) need to be installed above the first rear tub 112, which restricts the installation direction of the second outer tub 21 in the front-rear direction within the housing 72. In order to reduce or avoid changes to the dimensions of the housing 72, the axial depth of the second rear tub 212 is reduced, and the rear end face of the second rear tub 212 is moved forward to make room for the installation of other components.

[0084] Furthermore, such as Figure 1 As shown, the front end face of the first front tub 111 is coplanar with the front end face of the second front tub 211, so as to increase the capacity of the second outer tub 21 and also improve the aesthetics of the outer contour of the front of the garment processing equipment 100.

[0085] In one embodiment, the front tub structure and the rear tub structure are connected by fasteners (such as screws), specifically, as follows: Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the first front bucket 111 is provided with a plurality of first mounting holes 1111, and the first rear bucket 112 is provided with a plurality of second mounting holes 1121. The first mounting holes 1111 and the second mounting holes 1121 are matched one by one and fastened together by screws. The second front bucket 211 is provided with a plurality of third mounting holes 2112, and the second rear bucket 212 is provided with a plurality of fourth mounting holes 2122. The third mounting holes 2112 and the fourth mounting holes 2122 are matched one by one and fastened together by screws, thereby realizing the assembly of the front bucket structure and the rear bucket structure.

[0086] In one embodiment, a sealing ring is configured to ensure a tight seal at the assembly point of the front and rear tub structures.

[0087] Furthermore, such as Figure 8 and Figure 9 As shown, the first front bucket 111 and the first rear bucket 112 are sealed by the first sealing ring 113, and the second front bucket 211 and the second rear bucket 212 are sealed by the second sealing ring 213. The sealing structure is simple and easy to assemble.

[0088] Furthermore, such as Figures 7 to 10 As shown, the first front tub 111 and the second front tub 211 are connected by a connecting rib 3. The rear end of the connecting rib 3 is provided with a first snap-fit ​​protrusion 31 and a second snap-fit ​​protrusion 32. A slot 33 is formed between the first snap-fit ​​protrusion 31 and the second snap-fit ​​protrusion 32. The front end face of the first rear tub 112 is provided with a first annular slot 1122, and the front end face of the second rear tub 212 is provided with a second annular slot 2123. The first annular slot 1122 and the second annular slot 2123 are separated by a third snap-fit ​​protrusion 8 at the integral connection between the first rear tub 112 and the second rear tub 212. The first sealing ring 113 is engaged in the first annular groove 1122, the second sealing ring 213 is engaged in the second annular groove 2123, the third engaging protrusion 8 is inserted into the groove 33, the first engaging protrusion 31 is inserted into the first annular groove 1122 and presses backward against the first sealing ring 113, the second engaging protrusion 32 is inserted into the second annular groove 2123 and presses backward against the second sealing ring 213, and the rear end of the second front barrel 211 is inserted into the second annular groove 2123 and presses backward against the second sealing ring 213, thereby ensuring the sealing between the front barrel structure and the rear barrel structure.

[0089] In one implementation, such as Figure 1 and Figure 2 As shown, the garment processing equipment also includes multiple shock-absorbing columns 91 and multiple suspension springs 92. The shock-absorbing columns 91 are used to support the first outer tub 11, and the suspension springs 92 are used to lift the first outer tub 11. The shock-absorbing columns 91 and the suspension springs 92 cooperate to install the first outer tub 11 on the frame 71.

[0090] Furthermore, such as Figure 1 and Figure 2 As shown, there are four shock-absorbing columns 91. Two shock-absorbing columns 91 are respectively supported on the bottom sides of the front end of the first front tub 111, and the other two shock-absorbing columns 91 are respectively supported on the bottom sides of the first rear tub 112. Of course, the number of shock-absorbing columns 91 is not limited to four; it can also be three, five, or even more. To ensure stable operation of the washing tub assembly and save space, the number of shock-absorbing columns 91 is preferably four.

[0091] Furthermore, such as Figure 1 and Figure 6 As shown, there are two suspension springs 92, which are respectively connected to the left and right sides of the upper part of the first front barrel 111. In one specific embodiment, as... Figure 1 and Figure 11 As shown, since a second outer tub 21 is respectively provided on both sides of the top of the first outer tub 11, the assembly space for the suspension spring 92 is limited. Therefore, in this solution, the garment processing equipment 100 is also provided with two reinforcing mounting plates 73. The length of the reinforcing mounting plates 73 extends along the front-rear direction of the garment processing equipment 100. The two reinforcing mounting plates 73 are respectively located on the left and right sides of the first outer tub 11, and the reinforcing mounting plates 73 are connected to the housing 72. The suspension spring 92 and the reinforcing mounting plates 73 are matched one-to-one. The top end of the suspension spring 92 is connected to the reinforcing mounting plate 73, and the bottom end of the suspension spring 92 is connected to the first outer tub 11. In this solution, by adding the reinforcing mounting plates 73 to install the suspension spring 92, interference between the installation of the suspension spring 92 and the second washing tub assembly 2 is avoided, and the arrangement is reasonable and compact. In a specific embodiment, since the axial depth of the first front tub 111 is greater than the axial depth of the first rear tub 112, the bottom end of the suspension spring 92 is connected to the outer wall of the first front end 111 to ensure the stability of the overall structure.

[0092] In one implementation, such as Figure 1 As shown, the garment processing equipment 100 is also equipped with a balance block 6, which is connected to the front tub structure to reduce the vibration generated by the first outer tub 11 and the second outer tub 21 during operation. Furthermore, since the first washing tub assembly 1 is large in size and bears a heavy load, the vibration is more obvious during operation. Therefore, connecting the balance block 6 to the first front tub 111 can directly and effectively dampen the vibration of the first washing tub assembly 1, thereby significantly reducing the vibration amplitude of the entire machine.

[0093] In one embodiment, the garment processing device 100 includes a first washing tub assembly 1, two second washing tub assemblies 2, and three direct drive motors (not shown in the figure) to drive the three washing tub assemblies separately and independently. Compared with the traditional belt drive technology, the direct drive motors used in this solution have stronger power and occupy less space.
