For the ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.
[0045] The laundry processing device 100 in the embodiment of the application can be a washing machine, a drying machine, a washing-drying integrated machine or the like.
[0046] Please refer to Figures 1 to 3a The laundry processing device 100 provided by the embodiment of the application comprises a box body 10, a barrel structure 20, a driving member (not shown in the figure), a hanging spring 40 and a damping assembly 50.
[0047] The barrel structure 20, the driving member, the hanging spring 40 and the damping assembly 50 are all accommodated inside the box body 10. The two ends of the hanging spring 40 are connected to the inner wall of the box body 10 and the barrel structure 20 respectively, and the damping assembly 50 is connected to the bottom of the barrel structure 20, for balancing the vibration generated when the laundry processing device 100 works. The driving member is used for driving the inner barrel in the barrel structure 20 to rotate, so as to wash the laundry inside. The driving member is preferably a dd motor, and compared with the traditional belt driving, the dd motor has stronger overall performance and improves the washing effect.
[0048] The barrel structure 20 at least comprises a first barrel 21, a second barrel 22 and a third barrel 23, and the first barrel 21 and the second barrel 22 are symmetrically arranged with the vertical plane where the central axis of the third barrel 23 is located. The arrangement of the first barrel 21, the second barrel 22 and the third barrel 23 can meet the washing requirements of different types of laundry of users.
[0049] The first tub 21 and the second tub 22 are located to the upper left and upper right of the third tub 23, respectively, and the inner diameter of the cross-section of the first tub 21 and the second tub 22 is smaller than the inner diameter of the cross-section of the third tub 23. The positional distribution of the first tub 21, the second tub 22 and the third tub 23 can ensure the overall space occupied by the clothing processing equipment 100.
[0050] The first barrel 21 includes a first inner barrel 212 and a first outer barrel 211, with a first heating chamber 213 located between them. The second barrel 22 includes a second inner barrel 222 and a second outer barrel 221, with a second heating chamber 223 located between them. The third barrel 23 includes a third inner barrel 232 and a third outer barrel 231, with a third heating chamber 233 located between them. The first heating chamber 213 and the second heating chamber 223 are located near the bottom of the first outer barrel 211 and the second outer barrel 221, respectively, and in the horizontal direction, the first heating chamber 213 and the second heating chamber 223 are offset in opposite directions. The third heating chamber 233 is located at the bottom of the third outer barrel 231.
[0051] The garment processing equipment 100 also includes a heating assembly, which includes a first heating element (not shown in the figure), a second heating element (not shown in the figure), and a third heating element 30. The first heating element, the second heating element, and the third heating element 30 are respectively installed in the first heating chamber 213, the second heating chamber 223, and the third heating chamber 233 to heat the washing water located in the first heating chamber 213, the second heating chamber 223, and the third heating chamber 233, respectively.
[0052] Please refer to Figure 1 and Figure 3a The first inner tub 212, the second inner tub 222, and the third inner tub 232 are cylindrical in shape. Driven by three driving components, they rotate relative to the first outer tub 211, the second outer tub 221, and the third outer tub 231 to wash the clothes inside. The first outer tub 211, the second outer tub 221, and the third outer tub 231 are also nearly cylindrical in shape. A first heating chamber 213 and a second heating chamber 223 extend from the bottom of the first outer tub 211 and the second outer tub 221, respectively. This means that when the clothing handling device 100 does not have a heating function, the first outer tub 211, the second outer tub 221, and the third outer tub 231 are also cylindrical in shape.
[0053] To reduce the overall space occupied by the garment processing equipment 100, the first heating chamber 213 and the second heating chamber 223 are respectively located below the first inner tub 212 and the second inner tub 222, offset away from the third tub 23. There is a large space between the first tub 21 and the third tub 23 near the inner wall of the housing 10, which increases the heating space of the first heating chamber 213. This larger heating space allows for the installation of a higher-power heating element, thereby improving the heating efficiency of the washing water in the first tub 21, and further enhancing the overall washing efficiency of the garment processing equipment 100.
[0054] The first heating element, the second heating element, and the third heating element 30 are heating tubes, but they are not limited to these.
[0055] In one alternative embodiment, please refer to Figure 1 , Figure 3a , Figure 3b and Figure 4 The first heating chamber 213 and the second heating chamber 223 are symmetrically arranged with respect to the vertical plane of the central axis of the third barrel 23. The first heating chamber 213 will be described in detail below.
[0056] The first heating chamber 213 has a first extending surface 2131, a second extending surface 2132, and a bottom surface 2133. The first extending surface 2131, the second extending surface 2132, the bottom surface 2133, and the outer wall of the first inner tub 212 form the first heating chamber 213. The first heating element heats the washing water located in the first heating chamber 213, and the heated washing water exchanges heat with the washing water in the first inner tub 212 during the rotation of the first inner tub 212, thereby heating the washing water in the first inner tub 212.
[0057] The bottom surface 2133 of the first heating chamber 213 is a horizontal plane to facilitate the installation of the first heating element. It should be noted that the first heating element is located within the first heating chamber 213 and needs to maintain a certain distance from the first extension surface 2131, the second extension surface 2132, the bottom surface 2133, and the outer wall of the first inner barrel 212 of the first heating chamber 213 to prevent the heat of the first heating element from damaging the inner wall of the first heating chamber 213. The horizontal plane of the bottom surface 2133 not only facilitates the installation of the first heating element but also improves the heating safety of the first heating element.
[0058] The width of the bottom surface 2133 of the first heating chamber matches the width of the first heating element. This can be understood as follows: on the horizontal plane, the safety distance between the first heating element and the first extension surface 2131 and the second extension surface 2132, plus the width of the first heating element, equals the width of the bottom surface 2133 of the first heating chamber.
[0059] A first connecting rib 2a is provided between the first barrel 21 and the third barrel 23. The first connecting rib 2a is located on the line connecting the center of the circle containing the cross-section of the first inner barrel 212 and the center of the circle containing the cross-section of the third inner barrel 232. This minimizes the distance between the first barrel 21 and the third barrel 23, that is, minimizes the thickness of the first connecting rib 2a, thereby ensuring that the space occupied by the barrel structure 20 is minimized.
[0060] In an optional embodiment, the thickness of the first connecting rib 2a (i.e., Figure 3b The arrow marked L1 shown is greater than or equal to 1.5mm to ensure the connection strength between the first barrel 21 and the third barrel 23, and to prevent leakage caused by deformation of the sealing ring during the assembly of the front and rear barrels.
[0061] In an optional embodiment, the second extension surface 2132 of the first heating chamber 213 is the tangent to the circle containing the cross-section of the first outer barrel 211, and the second extension surface 2132 corresponds to the connection between the first barrel 21 and the third barrel 23, that is, to the first connecting rib 2a.
[0062] The line connecting the center of the circle containing the cross-section of the first inner tub 212 and the center of the circle containing the cross-section of the third inner tub 232 passes through the position where the distance between the first tub 21 and the third tub 23 is minimized. While ensuring the strength of the tub structure 20, the smaller the distance between the first tub 21 and the third tub 23, and between the second tub 22 and the third tub 23, the smaller the space occupied by the tub structure 20, thus ensuring that the clothing processing equipment 100 occupies less space. It can be understood that the second extension surface 2132 corresponds to the connection point between the first tub 21 and the third tub 23, enabling the tub structure 20 to occupy less space.
[0063] Although the heating chamber has a large space, allowing for the installation of high-power heating elements, it's not always better to have a larger heating chamber. While ensuring sufficient space for the heating element installation, a smaller heating chamber ensures that the heating element is submerged even with a small amount of washing liquid in the tub, thus guaranteeing its safe operation.
[0064] In an optional embodiment, the first extending surface 2131 is a tangent to the circle containing the cross-section of the first outer tub 211. This allows the first heating chamber 213, formed by the first extending surface 2131, the bottom surface 2133, the second extending surface 2132, and the outer wall of the first inner tub 212, to have a smaller space while ensuring the installation of a high-power first heating element. This ensures that even when there is a small amount of washing water in the first tub 21, the first heating element can be submerged, guaranteeing heating safety and reducing the minimum amount of washing water used.
[0065] It should be noted that the third heating chamber 233 located at the bottom of the third inner tub 232 can be set based on the connection structure of other components at the bottom of the box 10. The third heating chamber 233 can be located directly below the third inner tub 232, or it can be offset towards the first inner tub 212 or the second inner tub 222. This application embodiment does not make specific limitations.
[0066] In one alternative embodiment, please refer to Figure 1 and Figure 5 The first barrel body 21 includes a first front barrel 214 and a first rear barrel 215, with the first front barrel 214 sealingly connected to the first rear barrel 215. The second barrel body 22 includes a second front barrel 224 and a second rear barrel 225, with the second front barrel 224 sealingly connected to the second rear barrel 225. The third barrel body 23 includes a third front barrel 234 and a third rear barrel 235, with the third front barrel 234 sealingly connected to the third rear barrel 235. The first front barrel 214, the second front barrel 224, and the third front barrel 234 are integrally formed, as are the first rear barrel 215, the second rear barrel 225, and the third rear barrel 235. The integral forming of the first front barrel 214, the second front barrel 224, and the third front barrel 234, as well as the first rear barrel 215, the second rear barrel 225, and the third rear barrel 235, not only ensures the overall structural strength of the barrel structure 20 but also improves the ease of installation of the barrel structure 20.
[0067] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. 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 only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
