[0008] The second processing tank assembly extends horizontally and includes a second outer tank and a second inner tank that rotates relative to the second outer tank.

[0009] The second outer tub is located above the first outer tub and is distributed on one side of the center of the first outer tub; the junction of the second outer tub and the first outer tub forms a first connection structure.

[0010] The second processing tank assembly further includes: a first heating chamber disposed at the bottom of the second outer tank, located vertically between the second outer tank and the second inner tank, and horizontally located outside the first connecting structure.

[0015] Optionally, the junction between the first connecting structure and the outer walls of the first outer barrel and the second outer barrel includes a first pre-treatment structure, wherein the cross-section of the junction forms an obtuse angle or an arc.

[0016] Optionally, the garment processing equipment further includes a housing, wherein both the first outer tub and the second outer tub are located within the housing; the difference in distance between the outer side wall of the second outer tub and the outer side wall of the first outer tub from the side wall of the housing is less than 10 mm.

[0017] Optionally, the first heating chamber is located within the space enclosed by the second inner barrel, the first outer barrel, and the side wall of the box body;

[0018] The first heating chamber includes at least a first extension section extending outward and downward from the second outer barrel. One end of the first extension section is tangent to the side wall of the second outer barrel, and the other end is connected to the connecting rib, such that the connecting rib is distributed between the outer peripheral wall of the first outer barrel and the first extension section. The radial thickness of the connecting rib is less than or equal to the minimum spacing between the arcuate outer peripheral walls of the first outer barrel.

[0019] Optionally, the first heating chamber further includes a second extension section and a connecting section, the second extension section being tangent to the side wall of the other side of the second outer barrel; the first extension section and the second extension section are connected by the connecting section, which extends horizontally.

[0020] Optionally, the second outer tub and the first outer tub are integrally formed; the first outer tub includes a first front tub and a first rear tub connected and communicating with each other, and the second outer tub includes a second front tub and a second rear tub connected and communicating with each other; the first front tub and the second front tub are integrally formed, and the first rear tub and the second rear tub are integrally formed.

[0021] The garment processing device provided in this application includes: a first processing tub assembly extending horizontally, comprising a first outer tub and a first inner tub rotatable relative to the first outer tub; and a second processing tub assembly, at least two of which extend horizontally, comprising a second outer tub and a second inner tub rotatable relative to the second outer tub; wherein the two second outer tubs are located above the first outer tub and distributed on both sides of the center of the first outer tub; a first connecting structure is formed at the junction of the second outer tub and the first outer tub; the second processing tub assembly further includes: a first heating chamber disposed at the bottom of the second outer tub, vertically located between the second outer tub and the second inner tub, and horizontally located outside the first connecting structure. It can be seen that the garment processing device of this application, by placing the second outer tub above the first outer tub and distributing it on both sides of the center of the first outer tub, makes the structure more compact. Furthermore, by setting the first heating chamber vertically between the second outer tub and the second inner tub, and horizontally located outside the first connecting structure, space utilization is more efficient. Therefore, the garment processing device of this application has a more compact structure and more efficient space utilization.

[0038] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0039] To address the technical problems in related technologies, embodiments of this application provide a garment processing device. (Reference) Figures 1-4 The garment processing equipment includes:

[0040] The first processing tank assembly extends horizontally and includes a first outer tank 11 and a first inner tank 12 that rotates relative to the first outer tank 11.

[0041] The second processing tank assembly extends horizontally and includes a second outer tank 21 and a second inner tank 22 that rotates relative to the second outer tank 21.

[0042] The second outer barrel 21 is located above the first outer barrel 11 and is distributed on one side of the center of the first outer barrel 11; the junction of the second outer barrel 21 and the first outer barrel 11 forms a first connection structure 30.

[0043] The second processing tank assembly further includes a first heating chamber 40, which is disposed at the bottom of the second outer tank 21, located vertically between the second outer tank 21 and the second inner tank 22, and horizontally located outside the first connecting structure 30.

[0044] The clothing processing device in this application embodiment can be a washing machine, such as a front-loading washing machine. It is understood that it can also be a dryer, a washer-dryer combo, or other clothing processing devices. For clarity, the following description primarily uses a front-loading washing machine as an example. It is understood that the technical solutions described below can also be applied to other clothing processing devices.

[0045] Understandably, the processing tank of the first processing tank assembly is the large tank, and the processing tank of the second processing tank assembly is the small tank. The operation of the two processing tank assemblies is independent of each other; that is, the control components of the garment processing equipment can control the operation of only the first processing tank assembly, only the second processing tank assembly, or both processing tank assemblies. For the sake of brevity, general terms are sometimes used for unified description. For example, the first and second processing tank assemblies can be collectively referred to as processing tank assemblies, and the first outer tank 11 and the second outer tank 21 can be collectively referred to as outer tanks, and so on. Understandably, the first and second processing tank assemblies, in addition to the outer and inner tanks, may also include other components such as a motor that drives the inner tank to rotate; these will not be detailed here.

[0046] Understandably, there can be one or more second processing bucket components. If multiple second processing bucket components are set, their operation can also be independent of each other, which will not be elaborated further.

[0047] Understandably, due to the presence of a first processing drum assembly and a second processing drum assembly, and their vertical arrangement, the space for the heating chamber in the second processing drum assembly, i.e., the space for the first heating chamber 40, is relatively small. Therefore, it is positioned vertically between the second outer drum 21 and the second inner drum 22, and horizontally outside the first connecting structure 30. In other words, the first heating chamber 40 is located in the intersection area of ​​the first connecting structure 30 and the second inner drum 22. This allows for full utilization of the limited space in the garment processing equipment.

[0048] Specifically, an electrically energized heating element can be installed inside the first heating chamber 40, and multiple through holes for water to pass through are provided between the first heating chamber 40 and the second inner tank 22. This allows the water in the first heating chamber and the water in the second inner tank 22 to be interconnected, and the heating element can heat the water in the second inner tank 22.

[0049] In the garment processing device of this application embodiment, the second outer tub 21 is positioned above the first outer tub 11 and distributed on both sides of the center of the first outer tub 11, making the structure more compact. Furthermore, the first heating chamber 40 is positioned vertically between the second outer tub 21 and the second inner tub 22, and horizontally outside the first connecting structure 30, resulting in more efficient space utilization.

[0050] In other embodiments of this application, reference is made to Figure 4 and Figure 5 The second processing tank assembly has two parts, and the first heating chambers 40 of the two second outer tanks 21 and the first connecting structure 30 connected to them are symmetrically distributed about the axis of the first outer tank 11.

[0051] Having two secondary processing tanks better suits the needs of typical households; for example, one tank can be used for underwear, and the other for socks. The structure isn't overly complex, and the size doesn't need to be increased significantly. It's understandable that in some cases, more than one secondary processing tank could be used.

[0052] Understandably, the two second outer tubs 21 are positioned above the first outer tub 11, which makes the center of gravity of the garment handling equipment more stable. The two second outer tubs 21 are distributed on both sides of the center of the first outer tub 11; that is, the centers of the three tubs are connected to form a triangle, thus making the structure more stable.

[0053] First, the symmetrical arrangement of the first connecting structure 30 makes the distribution structure of the three outer barrels more stable. Second, the symmetrical distribution of the first heating chamber 40 makes the distribution of the first heating chamber and even the second processing barrel assembly relative to the first processing barrel assembly more reasonable, optimizing the structure. The symmetrical distribution can be such that the centers of the three barrels form an isosceles triangle. It should be noted that the symmetrical distribution about the axis of the first outer barrel 11 can also be a symmetrical distribution about the vertical plane containing the axis. Figure 4 and Figure 5 The middle part is marked as P1.

[0054] Specifically, in addition to the symmetrical distribution, the first heating chambers 40 of the two second outer barrels 21 and the two first connecting structures 30 are also at the same height, which is more conducive to the balance of the two second processing barrel assemblies during operation.

[0055] In other embodiments of this application, reference continues to be made to... Figure 4 The first connecting structure 30 includes connecting ribs 31, which are evenly distributed on both sides at the junction.

[0056] One side of the two sides is the first outer barrel 11, and the other side is the second outer barrel 21. That is, the connecting ribs 31 are evenly distributed on the side walls of the first outer barrel 11 and the second outer barrel 21, making the connection structure more stable and reliable.

[0057] It is understood that the first connecting structure 30 may also include detachable connectors such as bolts, so that the firmness between the second outer barrel 21 and the first outer barrel 11 can be further strengthened on the basis of the connecting rib 31.

[0058] In some other embodiments of this application, the connecting rib 31 is disposed on the line connecting the centers of the first outer barrel 11 and the second outer barrel 21.

[0059] In this way, the first outer tub 11, through the connecting rib 31, can better support the second outer tub 21. That is, the connecting rib 31, without interfering with the first heating chamber 40, is positioned as close as possible to the direct below the second outer tub 21. The line connecting the centers of the first outer tub 11 and the second outer tub 21 is... Figure 4 The middle part is marked as L1.

[0060] In other embodiments of this application, the wall thickness of the first outer barrel 11 is W; the radial thickness of the connecting rib 31 is T, and is set as: W <T<2W。

[0061] In this way, the connecting rib 31 can have sufficient strength while reducing the space occupied by the connecting rib 31.

[0062] Specifically, W can be 1mm-2mm, and T can be 1.5mm-3mm.

[0063] In other embodiments of this application, reference continues to be made to... Figure 4 The junction of the first connecting structure 30 with the outer walls of the first outer barrel 11 and the second outer barrel 21 includes a first pre-treatment structure 51, wherein the cross-section of the junction forms an obtuse angle or an arc.

[0064] In this way, there are no sharp corners or other structures that could easily cause stress concentration at the joints, thus increasing the strength and stability of the structure.

[0065] The first pre-processing structure 51 can be formed in one step, such as by injection molding, or it can be formed by multiple processes, such as local cutting after injection molding, which will not be described in detail.

[0066] The cross section here refers to the cross section cut along the radial direction of the outer barrel.

[0067] In other embodiments of this application, reference is made to Figure 1The garment processing equipment also includes a housing 60, in which the first outer tub 11 and the second outer tub 21 are both located. The difference in distance between the outer side wall of the second outer tub 21 and the outer side wall of the first outer tub 11 from the side wall of the housing 60 is less than 10 mm.

[0068] In this way, the second outer tub 21 is positioned as far outward as possible, and the outer wall of the second outer tub 21 can even be vertically aligned with the outer wall of the first outer tub 11. This reduces the height of the second outer tub 21, ensuring that the overall height of the garment processing equipment does not increase even when the second outer tub 21 is added.

[0069] In some other embodiments of this application, the motor driving the inner tub to rotate can be a direct-drive motor (DD motor). DD motors have unique characteristics such as low speed and high torque, simple structure, reduced mechanical loss, low noise, and low maintenance. This allows for better adaptation to clothing processing equipment with multiple second processing tub assemblies.

[0070] In some other embodiments of this application, the second outer barrel 21 and the first outer barrel 11 are integrally formed.

[0071] In this way, on the one hand, there is no need for assembly, which simplifies the structure and reduces manufacturing costs; on the other hand, it makes the structure between the three outer barrels more stable.

[0072] In other embodiments of this application, reference is made to Figure 2 and Figure 6 The first outer tub 11 includes a first front tub 111 and a first rear tub 112 connected and communicating with each other, and the second outer tub 21 includes a second front tub 211 and a second rear tub 212 connected and communicating with each other; the first front tub 111 and the second front tub 211 are integrally formed, and the first rear tub 112 and the second rear tub 212 are integrally formed.

[0073] Similarly, a one-piece molded structure has the advantages of reducing manufacturing costs and making the structure more robust. Dividing an outer tub into a front tub and a rear tub makes it easier to install and maintain the inner tub.

[0074] As before, the first front cylinder 111 and the second front cylinder 211 are collectively referred to as the front cylinder, and the first rear cylinder 112 and the second rear cylinder 212 are collectively referred to as the rear cylinder.

[0075] Specifically, sealing rings are provided at the mounting points of the front and rear cylinders. On the end face, the sealing rings encircle the front or rear cylinder.

[0076] In other embodiments of this application, reference is made to Figure 5 The first heating chamber 40 is located within the space enclosed by the second inner barrel 22, the first outer barrel 11, and the side wall of the box body 60;

[0077] refer to Figure 7 The first heating chamber includes at least a first extension section 41 extending outward and downward from the second outer barrel 21. One end of the first extension section 41 is tangent to the side wall of the second outer barrel, and the other end is connected to the connecting rib, such that the connecting rib is distributed between the outer peripheral wall of the first outer barrel and the first extension section 41; the radial thickness of the connecting rib is less than the minimum spacing between the arc-shaped outer peripheral walls of the first outer barrel.

[0078] Specifically, the space enclosed by the second inner barrel 22, the first outer barrel 11, and the side walls of the housing 60 is approximately triangular. Placing the first heating chamber 40 here allows for full utilization of the space. Furthermore, this space is also located below the second inner barrel 22, making it suitable for accommodating the heating chamber.

[0079] Specifically, if the connecting rib 31 is directly connected to the circumferential arc outer peripheral wall of the first outer barrel 11 and the circumferential outer wall of the second outer barrel 21 respectively, the wall thickness of the connecting rib 31 at various parts along the circumference of the first outer barrel 11 will vary greatly. This will cause the connecting rib 31 to easily deform during the integral injection molding process of the first outer barrel 11 and the second outer barrel 21, resulting in an increased product defect rate. Therefore, in this solution, the first extension section 41 is configured to be tangent to the circumference of the outer wall of the second outer barrel 21, and the radial thickness of the connecting rib is limited to be less than the minimum distance between the outer peripheral wall of the first outer barrel and the arc outer peripheral wall of the second outer barrel. The connecting rib 31 is connected to the first extension section 41 and the first outer barrel 11 respectively. By optimizing the setting position of the connecting rib 31, the wall thickness of the connecting rib 31 at various parts along the circumference of the first outer barrel 11 is made as equal as possible or the difference is small, so as to reduce the product defect rate.

[0080] Understandably, due to the presence of the first heating chamber, the outer wall of the second outer barrel is partly arc-shaped and partly non-arc-shaped, for example, it could be a straight line. (Reference) Figure 4 The minimum spacing is the minimum spacing between the arc portion of the second outer barrel and the first outer barrel, without involving the non-arc portion of the second outer barrel.

[0081] In other embodiments of this application, the first heating chamber further includes a second extension 42 and a connecting section 43, the second extension 42 being tangent to the side wall of the other side of the second outer barrel; the first extension 41 and the second extension 42 are connected by the connecting section 43, which extends horizontally.

[0082] The second extension 42 is tangent to the side wall of the other side of the second outer barrel, meaning the second extension 42 is an inwardly inclined straight line. This makes the structure of the first heating chamber more compact and stable.

[0083] The connecting section 43 extends horizontally, meaning the bottom wall of the first heating chamber is horizontal, which facilitates the installation of the heating element.

[0084] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the technical solutions contained in this application. Various modifications and changes can be made to the above embodiments without departing from the scope of this application. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments merely illustrate several implementations of this application and do not limit the scope of protection of this patent application.
