[0041] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

A first washing tub and a second washing tub are arranged side by side inside the frame. The frame includes a rear support, which is located near the bottom of the first washing tub and the bottom of the second washing tub.

[0047] It achieves water and electricity separation, ensuring high safety; it allows the steam box to smoothly deliver steam to both washing drums, achieving better steam care; it also makes wiring more convenient, solving the problem of water and electricity separation being impossible due to unsuitable placement of the electrical box and steam box in twin-drum washing machines.

[0048] Example 1

[0049] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, this embodiment provides a twin-tub washing machine, including:

[0050] The frame 1 has a first washing drum 41 and a second washing drum 42 arranged side by side inside it; the frame 1 includes a rear support, which is located near the bottom of the first washing drum 41 and the bottom of the second washing drum 42; specifically, the first washing drum 41 and the second washing drum 42 are arranged side by side in a vertical direction; the openings of the first washing drum 41 and the second washing drum 42 face the same direction.

[0051] The electrical box 21 is mounted on the rear bracket and located near the bottom of the first washing drum 41;

[0052] Steam box 22 is mounted on the rear bracket and located below electrical box 21;

[0053] Furthermore, such as Figure 3 and Figure 4 As shown, the rear support includes a first column 11, a second column 12, a rear crossbeam 13, and a back plate. The rear crossbeam 13 and the back plate 32 are both connected between the first column 11 and the second column 12. The rear crossbeam 13 includes a main crossbeam 131 and a secondary crossbeam 132. The main crossbeam 131 is bent towards the bottom of the first washing drum 41 to form the secondary crossbeam 132. The back plate 32 is located above the main crossbeam 131. The bottom wall of the electrical box 21 is set on the secondary crossbeam 132, and the side wall of the electrical box 21 near the back plate 32 is set on the back plate 32.

[0054] Specifically, such as Figure 10 As shown, the bottom wall of the electrical box 21 has points c1, c2, and c3 connected to the crossbeam sub-plate 132 and arranged sequentially. The distance between points c1 and c2 is c1c2, and the distance between points c2 and c3 is c2c3. The magnitude of the vertical force at point c1 is F. c1 The magnitude of the vertical force at point c2 is F. c2 The magnitude of the vertical force at point c3 is F. c3 Satisfying: 40mm < c1c2 < 60mm, 40mm < c2c3 < 60mm, F c1 =k c1 *F G F c2 =k c2 *F G F c3 =k c3 *F G ,

[0055] Among them, F G For the weight of electrical box 21, 0.1 < k c1 <0.2, 0.1<k c2 <0.2, 0.1<k c3 <0.2;

[0056] Preferably, c1c2 = c2c3 = 50mm, k c1 =k c2 =k c2 =1 / 6.

[0057] Furthermore, the side wall of the electrical box 21 near the back plate 32 has points c4, c5, and c6 connected to the back plate 32. The distance between points c4 and c5 is c4c5, and the distance between points c5 and c6 is c5c6. The magnitude of the horizontal force at point c4 is F. c41 The magnitude of the vertical force at point c4 is F. c42 The magnitude of the horizontal force at point c5 is F. c51 The magnitude of the vertical force at point c5 is F. c52 The magnitude of the horizontal force at point c6 is F. c61 The magnitude of the vertical force at point c6 is F. c62 Satisfying: 168mm < c4c5 < 208mm, 108mm < c5c6 < 148mm, F c41 =k c41 *F z F c42 =k c42 *F G F c51 =k c51 *F z F c52 =k c52 *F G F c61 =k c61 *F z F c62 =k c62 *F G .

[0058] To address the issue of the electrical box 21 not being securely fixed, this embodiment proposes that the crossbeam subplate 132 has points C1, C2, and C3 that connect to the bottom wall of the electrical box 21, with points C1, C2, and C3 corresponding to points C1, C2, and C3, respectively. A first fixing structure 1321 is formed at each of points C1, C2, and C3 to fix the electrical box 21. Specifically, the first fixing structure 1321 is a locking hole, and the electrical box 21 has a locking buckle. The buckle is embedded in the locking hole, thus connecting the electrical box 21 to the crossbeam main plate 131 and preventing the electrical box 21 from moving forward / backward and / or left / right.

[0059] To address the issue of inaccurate installation of the electrical box 21, this embodiment proposes that the crossbeam sub-plate 132 also forms a first guide structure 1322 for guiding the installation of the electrical box 21, so that the electrical box 21 is accurately installed on the crossbeam sub-plate 132; the first guide structure 1322 is a guide hole, and the crossbeam sub-plate 132 has multiple guide holes.

[0060] To address the issue that the low strength of the rear crossbeam 13 leads to its easy deformation and bending, this embodiment proposes that the crossbeam subplate 132 has a first anti-bending structure 1323, which is a protrusion and has at least two of them; this improves the strength of the rear crossbeam 13 and prevents the rear crossbeam 13 from deforming, bending, and swaying.

[0061] like Figure 5 and Figure 6 As shown, in view of the problem that the connection between the steam box 22 and the rear crossbeam 13 is inconvenient, this embodiment proposes that the twin-tub washing machine also includes a fixing plate 23; the fixing plate 23 is connected to the main crossbeam 131 and is located below the secondary crossbeam 132;

[0062] like Figure 11 As shown, the steam box 22 is mounted on the fixed plate 23. The steam box 22 has points a and b connected to the fixed plate 23, and the distance between points a and b is ab. The magnitude of the horizontal force at point a is F. a1 The magnitude of the vertical force at point a is F. a2 The magnitude of the horizontal force at point b is F. b1 The magnitude of the vertical force at point b is F. b2 Satisfying: 92mm < ab < 132mm, F a1 =k a1 *F z F a2 =k a2 *F G ,F b1 =k b1 *F z F b2 =k b2 *F G ,

[0063] Among them, F Z F represents the magnitude of the resonance force of a twin-tub washing machine. G The weight of steam box 22; 0.4 < k a1 <0.6, 0.4<k a2 <0.6, 0.4<k b1 <0.6, 0.4<k b2 <0.6;

[0064] Preferably, ab = 112 mm, ka1 =k a2 =k b1 =k b2 =0.5.

[0065] Furthermore, the fixing plate 23 has points A and B that connect to the steam box 22, with points A and B corresponding to points a and b, respectively; a fourth fixing structure 2321 is formed at both points A and B for connecting the fixing plate 23 and the steam box 22; specifically, the fourth fixing structure 2321 is a fixing hole; the fixing plate 23 also has a positioning structure 2322 for positioning when the fixing plate 23 is connected to the steam box 22, so that the steam box 22 is accurately set on the fixing plate 23; the positioning structure 2322 is a positioning hole or a positioning groove.

[0066] To address the unreliable connection between the fixing plate 23 and the rear crossbeam 13, this embodiment proposes that the fixing plate 23 includes a fixing main plate 231 and a fixing secondary plate 232. The fixing main plate 231 is arranged parallel to the crossbeam main plate 131 and connected to it. The fixing main plate 231 is bent to one side of the bottom of the first washing drum 41 to form the fixing secondary plate 232. The fixing secondary plate 232 is arranged parallel to the crossbeam secondary plate 132 and has a steam box 22. The crossbeam main plate 131 has a third fixing structure 1311 and the fixing main plate 231 has a second fixing structure 2311. The third fixing structure 1311 cooperates with the second fixing structure 2311 for connecting the crossbeam main plate 131 and the fixing main plate 231.

[0067] In addition, the main body of the crossbeam 131 has a second anti-bending structure 1313, which is a protrusion and protrudes towards the back plate 32; the second anti-bending structure 1313 has a fifth fixing structure for connecting the main body of the crossbeam 131 and the back plate 32; the second anti-bending structure 1313 can enhance the strength of the rear crossbeam 13.

[0068] like Figure 9 As shown, the twin-tub washing machine also includes a cabinet module 3, which includes the frame 1 described in any of the above claims; the first washing tub 41 and the second washing tub 42 can be independently inlet and outlet, avoiding cross-contamination and mutual staining of different clothes during washing, and realizing zoned washing;

[0069] Furthermore, the housing module 3 also includes a base 31, a first side plate, a second side plate, and a back plate 32; the frame 1 is a cuboid structure in general, with the base 31 at the bottom of the frame 1, a front panel at the front of the frame 1, a first side plate at the left side of the frame 1, and a second side plate at the right side of the frame 1.

[0070] Example 2

[0071] Unlike Embodiment 1, the first guide structure 1322 is a slot, and the crossbeam subplate 132 has multiple slots.

[0072] Example 3

[0073] Unlike Embodiment 1, this embodiment addresses the issue of unreliable connection between the fixing plate 23 and the rear crossbeam. The fixing plate 23 includes a main fixing plate 231 and a secondary fixing plate 232. The main fixing plate 231 is bent towards one side of the bottom of the first washing drum to form the secondary fixing plate 232. The main crossbeam plate 131 has a second guide structure 1312, and the main fixing plate 232 has a third guide structure. The second guide structure 1312 cooperates with the third guide structure to guide the connection between the main crossbeam plate 131 and the main fixing plate 231. The second guide structure 1312 is a guide hole or slot, and the main crossbeam plate 131 has multiple guide holes or slots. Correspondingly, the third guide structure is a guide post or latch, and the main fixing plate 231 has multiple guide posts or latches.
