[0067] It should be noted that the bottom of the outer drum 2 is formed by combining the reinforcing plate 23 and the rear wall 22 of the drum, thereby improving the structural strength and rigidity of the bottom of the outer drum 2, which can help to increase the maximum speed of the entire clothing processing device, reduce the safety gap between the inner drum and the outer drum 2, and further help to increase the volume of the washing chamber inside the inner drum.
[0068] like Figure 3 and Figure 7 As shown, in some embodiments, the reinforcing plate 23 can be fixed to the front wall of the cylinder rear wall 22 by welding. In this way, the reinforcing plate 23 and the cylinder rear wall 22 are fixed as one body by welding, which can improve the connection stability between the reinforcing plate 23 and the cylinder rear wall 22, and is conducive to improving the structural strength and rigidity of the cylinder bottom of the outer cylinder 2.

Specifically, the front side of the reinforcing rib 24 may abut against the rear wall of the reinforcing plate 23, and the rear side of the reinforcing rib 24 may abut against the front wall of the cylinder rear wall 22. By disposing the reinforcing rib 24 between the reinforcing plate 23 and the cylinder rear wall 22, the reinforcing plate 23 and the cylinder rear wall 22 can be combined to form a double-layer structure with a front-to-back spacing. This can improve the structural strength and rigidity of the reinforcing plate 23 and the cylinder rear wall 22, reduce the weight of the cylinder bottom of the outer cylinder 2, and help reduce costs.
[0072] like Figure 7 and Figure 8 As shown, in some embodiments, the reinforcing rib 24 can be integrally formed on the front wall of the barrel rear wall 22. The reinforcing rib 24 can be arranged to protrude forward from the front wall of the barrel rear wall 22. The rear wall of the reinforcing plate 23 can abut against the front side of the reinforcing rib 24. Therefore, the reinforcing rib 24 can be integrally formed on the front wall of the barrel rear wall 22 through integral injection molding; the reinforcing plate 23 is then fixed to the front side of the barrel rear wall 22, so that the rear wall of the reinforcing plate 23 abuts against the front side of the reinforcing rib 24, which helps to simplify the structure and reduce production costs.
[0073] It should be noted that in some other embodiments, the reinforcing ribs 24 can be integrally formed on the rear wall of the reinforcing plate 23. The reinforcing ribs 24 can be integrally formed on the rear wall of the reinforcing plate 23 by integral injection molding. The reinforcing plate 23 and the reinforcing ribs 24 can then be fixed to the front wall of the cylinder rear wall 22 by welding or screwing.
[0074] like Figure 3 and Figure 7 As shown, in some embodiments, the reinforcing plate 23 can be welded and fixed to the front wall of the reinforcing rib 24. The reinforcing plate 23 is fixed to the reinforcing rib 24 by welding, so that the reinforcing plate 23, the reinforcing rib 24 and the cylinder rear wall 22 are connected as a whole, which can improve the connection stability between the reinforcing plate 23, the reinforcing rib 24 and the cylinder rear wall 22, and is conducive to improving the structural strength and rigidity of the cylinder bottom of the outer cylinder 2.
[0075] In some embodiments, the reinforcing plate 23 may also be detachably mounted on the front wall of the reinforcing rib 24 by screws. The use of screws to fix the reinforcing plate 23 and the reinforcing rib 24 facilitates installation and removal.
[0076] In some embodiments, the front wall of the reinforcing rib 24 may be provided with a fixing hole (not shown). The fixing hole may be a threaded hole. The reinforcing plate 23 may be provided with a through-hole (not shown) arranged opposite the fixing hole. The reinforcing plate 23 may be removably fixed to the front wall of the reinforcing rib 24 via the fixing hole and the through-hole. Specifically, screws are passed through the through-holes and threadedly connected to the fixing holes, so that the reinforcing plate 23 can be fixed to the front wall of the reinforcing rib 24 by the screws cooperating with the fixing hole and the through-hole.
[0077] like Figure 3 and Figure 7 As shown, in some embodiments, a liquid balancing weight chamber 25 can be formed between the rear wall of the reinforcing plate 23 and the front wall of the barrel rear wall 22. The liquid balancing weight chamber 25 is sealed and isolated between the rear wall of the reinforcing plate 23 and the front wall of the barrel rear wall 22. The reinforcing ribs 24 can be arranged inside the liquid balancing weight chamber 25. In this way, by forming the liquid balancing weight chamber 25 between the reinforcing plate 23 and the barrel rear wall 22, liquid (such as water or other liquids) can be input into the liquid balancing weight chamber 25, thereby forming a water balancing weight, thereby realizing the balancing weight function of the outer barrel 2. In addition, by adjusting the weight of the liquid input into the liquid balancing weight chamber 25, the weight of the outer barrel 2 can be adjusted, thereby realizing the adjustable weight of the outer barrel 2, that is, realizing the adjustment of the balancing weight of the outer barrel 2.

[0084] like Figure 9 and Figure 10 As shown, in some embodiments, the laundry processing apparatus may include a liquid level detection device 26. The liquid level detection device 26 may be disposed on the rear wall 22 of the tub. The liquid level detection device 26 may be used to detect the liquid level within the liquid counterweight chamber 25. Thus, after liquid is input into the liquid counterweight chamber 25 through the liquid inlet 223 to a predetermined height, liquid input may be stopped, maintaining the liquid within the liquid counterweight chamber 25 at the predetermined height, thereby controlling the counterweight of the outer tub 2.
[0085] It should be noted that the preset height of the liquid in the liquid counterweight chamber 25 can be adjusted as needed and is not limited here.
[0086] like Figure 7 、 Figure 9 and Figure 10As shown, in some embodiments, the liquid level detection device 26 may include a first detection portion 261 and a second detection portion 262. The first detection portion 261 may be provided on the rear wall 22 of the cylinder. One end of the first detection portion 261 may extend into the liquid counterweight chamber 25. The other end of the first detection portion 261 may be exposed on the rear wall of the cylinder rear wall 22 and may be used for an external power supply. The second detection portion 262 may be provided on the rear wall 22 of the cylinder. The second detection portion 262 may be spaced apart from the first detection portion 261. One end of the second detection portion 262 may extend into the liquid counterweight chamber 25. The other end of the second detection portion 262 may be exposed on the rear wall of the cylinder rear wall 22 and may be used for an external power supply. In this way, the first detection portion 261 and the second detection portion 262 may be respectively connected to the positive and negative poles of the external power supply. When the liquid level in the liquid counterweight chamber 25 is higher than the first detection portion 261 and the second detection portion 262, the liquid will submerge the first detection portion 261 and the second detection portion 262, and the first detection portion 261 and the second detection portion 262 will be connected to each other through the liquid, thereby generating a liquid level signal. Based on this liquid level signal, the liquid supply to the liquid counterweight chamber 25 can be stopped, thereby maintaining the liquid in the liquid counterweight chamber 25 at a preset height.
[0087] In some embodiments, the liquid level detection device 26 can be connected to the liquid inlet valve 13 by signal. The first detection part 261 and the second detection part 262 can be connected to the liquid inlet valve 13 by signal, respectively. In this way, when the first detection part 261 and the second detection part 262 are connected to each other and generate a liquid level height signal, the liquid level height signal can generate a corresponding control signal, and transmit the control signal to the liquid inlet valve 13. The liquid inlet valve 13 can control the liquid inlet valve 13 to stop the liquid inlet according to the control signal corresponding to the liquid level height signal, so that the liquid inlet port 223 stops transporting liquid into the liquid counterweight chamber 25, thereby maintaining the liquid in the liquid counterweight chamber 25 at a preset height.
[0088] In some embodiments, the second detection portion 262 can be arranged below the first detection portion 261 at intervals. The position height of the first detection portion 261 is higher than the position height of the second detection portion 262. In this way, when the liquid inlet 223 transports liquid into the liquid counterweight chamber 25, as the liquid level in the liquid counterweight chamber 25 rises, the liquid preferentially submerges the second detection portion 262; when the liquid level rises to the position height of the first detection portion 261, the liquid can simultaneously submerge the first detection portion 261 and the second detection portion 262. At this time, the first detection portion 261 and the second detection portion 262 can be connected to each other through the liquid, thereby generating a liquid level height signal. Therefore, the position height of the first detection portion 261 can be used as a preset height position of the liquid.
[0089] It should be noted that, in other embodiments, the second detection portion 262 may also be spaced apart and disposed above the first detection portion 261. In this way, the height of the second detection portion 262 may also serve as the preset height of the liquid.
[0090] In other embodiments, the first detection portion 261 and the second detection portion 262 may also be arranged horizontally and spaced apart. In this way, when liquid is transported within the liquid counterweight chamber 25, the liquid can simultaneously submerge the first detection portion 261 and the second detection portion 262. The height of the first detection portion 261 and the second detection portion 262 can serve as the preset height of the liquid.
[0091] Figure 11 yes Figure 3 A front view of the middle reinforcing plate 23.
[0092] like Figure 3 、 Figure 7 and Figure 11 As shown, in some embodiments, the reinforcing plate 23 can be annular. The reinforcing plate 23 can be arranged circumferentially around the bearing seat 221. By placing the reinforcing plate 23 annularly around the bearing seat 221, the reinforcing plate 23 does not increase the thickness of the bearing seat 221 in the front-to-back direction, thereby increasing the bearing span and encroaching on the internal volume of the outer cylinder 2. By placing the reinforcing plate 23 annularly around the bearing seat 221, the bearing span can be reduced, the space occupied by the reinforcing plate 23 at the bottom of the outer cylinder 2 can be reduced, and the internal volume of the outer cylinder 2 can be increased.
[0093] In some embodiments, the liquid balancing weight chamber 25 can be annular. The liquid balancing weight chamber 25 can be arranged circumferentially around the bearing seat 221. This annular arrangement of the liquid balancing weight chamber 25 around the bearing seat 221 can help reduce the bearing span and save space occupied by the liquid balancing weight chamber 25 at the bottom of the outer cylinder 2.
[0094] In some embodiments, the inner edge of the reinforcing plate 23 can be connected to the outer edge of the bearing seat 221. The outer edge of the reinforcing plate 23 can be connected to the inner circumferential wall of the barrel body 21. In this way, by connecting the inner edge of the reinforcing plate 23 to the outer edge of the bearing seat 221 and the outer edge of the reinforcing plate 23 to the inner circumferential wall of the barrel body 21, the accommodating chamber 20 can be enclosed and formed between the inner circumferential wall of the barrel body 21 and the reinforcing plate 23 and the front wall of the bearing seat 221. In addition, the liquid counterweight chamber 25 can be formed in the area between the outer periphery of the bearing seat 221 and the inner circumferential wall of the barrel body 21.
[0095] like Figure 3 、 Figure 7 and Figure 8As shown, in some embodiments, an abutment portion 222 may be provided at the circumferential edge of the cylinder rear wall 22. The abutment portion 222 may be annular. The abutment portion 222 may be circumferentially arranged around the circumferential edge of the cylinder rear wall 22. The abutment portion 222 may be provided between the outer peripheral edge of the reinforcing plate 23 and the inner peripheral wall of the rear end of the cylinder body 21. In this way, when the reinforcing plate 23 is fixed to the front side of the cylinder rear wall 22, the circumferential edge of the reinforcing plate 23 may abut against the abutment portion 222 in front and back, so that the liquid counterweight chamber 25 between the reinforcing plate 23 and the cylinder rear wall 22 may be formed in the area between the outer periphery of the bearing seat 221 and the abutment portion 222.
[0096] In some embodiments, the peripheral edge of the reinforcing plate 23 can be fixed to the front wall of the abutment portion 222 by welding or screwing. In this way, by using the peripheral edge of the reinforcing plate 23 to be fixedly connected to the front wall of the abutment portion 222, the connection strength between the reinforcing plate 23 and the cylinder rear wall 22 can be improved, and the sealing performance of the liquid counterweight chamber 25 can be improved.
[0097] like Figure 7 and Figure 8 As shown, in some embodiments, a first gap (not shown) can be formed between the outer edge of the reinforcing plate 23 and the inner circumferential wall of the cylinder body 21. This first gap can be used to form a first weld. In this way, the outer edge of the reinforcing plate 23 can be welded to the inner circumferential wall of the cylinder body 21, which can help improve the connection strength between the reinforcing plate 23, the cylinder body 21, and the cylinder rear wall 22, and improve the sealing performance of the liquid counterweight chamber 25.
[0098] In some embodiments, a second gap (not shown) may be formed between the inner edge of the reinforcing plate 23 and the outer edge of the bearing seat 221. This second gap may be used to form a second weld. Thus, the inner edge of the reinforcing plate 23 may be welded to the outer edge of the bearing seat 221, thereby improving the connection strength between the reinforcing plate 23 and the cylinder rear wall 22 and enhancing the sealing of the liquid counterweight chamber 25.
[0099] like Figure 3 、 Figure 7 and Figure 8 As shown, in some embodiments, the reinforcing ribs 24 can be arranged in an elongated strip shape. The reinforcing ribs 24 can extend in the radial direction of the cylinder rear wall 22. Thus, the elongated structure of the reinforcing ribs 24 can increase the connection area between the reinforcing plate 23 and the cylinder rear wall 22. By extending the reinforcing ribs 24 in the radial direction of the cylinder rear wall 22, the reinforcing plate 23 can be fixed to the front side of the cylinder rear wall 22 from its inner edge to its outer edge, thereby improving the connection strength and stability between the reinforcing plate 23 and the cylinder rear wall 22.
[0100] In some embodiments, the reinforcing rib 24 can be provided on the outer periphery of the bearing seat 221. The reinforcing rib 24 can extend from the outer periphery of the bearing seat 221 toward the circumferential edge of the cylinder rear wall 22. In this manner, one end of the reinforcing rib 24 can be fixedly connected to the outer periphery of the bearing seat 221, thereby enhancing the connection strength and rigidity between the reinforcing plate 23, the reinforcing rib 24, and the bearing seat 221.
[0101] In some embodiments, the end of the reinforcing rib 24 away from the bearing seat 221 can extend to the abutment portion 222. The reinforcing rib 24 can extend in the radial direction of the cylinder rear wall 22 and be arranged between the outer peripheral edge of the bearing seat 221 and the abutment portion 222. In this way, the end of the reinforcing rib 24 away from the bearing seat 221 can be connected to the abutment portion 222, thereby improving the connection strength and rigidity between the cylinder body 21, the reinforcing rib 24, and the cylinder rear wall 22.
[0102] like Figure 3 、 Figure 7 and Figure 8 As shown, in some embodiments, multiple reinforcing ribs 24 may be provided. Multiple reinforcing ribs 24 may be protrudingly arranged at intervals on the front wall of the cylinder rear wall 22. Multiple reinforcing ribs 24 may be arranged within the liquid counterweight chamber 25. Multiple reinforcing ribs 24 may be circumferentially arranged around the bearing seat 221 at intervals. Multiple reinforcing ribs 24 may extend in different radial directions along the cylinder rear wall 22. In this way, the multiple reinforcing ribs 24 can cooperate to enhance the connection strength and rigidity between the reinforcing plate 23, the reinforcing ribs 24, and the cylinder rear wall 22, thereby improving the structural strength and rigidity of the bottom of the outer cylinder 2.
[0103] like Figure 3 、 Figure 7 and Figure 8 As shown, in some embodiments, a plurality of reinforcing ribs 24 can divide the liquid balancing weight chamber 25 into a plurality of balancing weight sub-cavities 251. The balancing weight sub-cavities 251 can be formed between two adjacent reinforcing ribs 24. The plurality of balancing weight sub-cavities 251 can be circumferentially spaced and arranged around the circumference of the bearing seat 221.
[0104] In some embodiments, the reinforcing rib 24 may be provided with a liquid-passing notch 241. The liquid-passing notch 241 can connect the counterweight subcavities 251 on both sides of the reinforcing rib 24. That is, adjacent counterweight subcavities 251 can be connected through the liquid-passing notch 241. In this way, the liquid inlet 223 can connect to any counterweight subcavity 251, delivering liquid to that counterweight subcavity 251. Liquid in that counterweight subcavity 251 can then flow through the liquid-passing notch 241 to the adjacent counterweight subcavity 251.
[0105] In some embodiments, the liquid-passing notch 241 may be formed at the front side of the reinforcing rib 24 . In other embodiments, the liquid-passing notch 241 may also be formed at other positions of the reinforcing rib 24 .
[0106] In some embodiments, there may be multiple liquid-passing notches 241. The multiple liquid-passing notches 241 may be sequentially spaced apart along the length of the reinforcing rib 24 on the front side of the reinforcing rib 24. Adjacent counterweight subcavities 251 may be interconnected through the multiple liquid-passing notches 241 corresponding to the reinforcing rib 24.
[0107] In some embodiments, the liquid inlet 223 can be disposed in the upper region of the barrel rear wall 22. The liquid inlet 223 can communicate with the counterweight subcavity 251 in the upper region of the liquid counterweight chamber 25. Thus, when the liquid inlet 223 delivers liquid to the counterweight subcavity 251 in the upper region of the liquid counterweight chamber 25, the liquid entering the counterweight subcavity 251 can flow through the liquid-passing notch 241 to the remaining counterweight subcavities 251.
[0108] It should be noted that, in other embodiments, the liquid inlet 223 can be located in the lower region of the barrel rear wall 22. The liquid inlet 223 can communicate with the counterweight subcavity 251 in the lower region of the liquid counterweight chamber 25. Thus, when the liquid inlet 223 delivers liquid to the counterweight subcavity 251 in the lower region of the liquid counterweight chamber 25, the liquid entering the counterweight subcavity 251 can also overflow through the liquid-passing notch 241 and flow into the remaining counterweight subcavities 251.
[0109] In other embodiments, the liquid inlet 223 may be provided in other areas of the barrel rear wall 22 .
[0110] Figure 12 yes Figure 11 Partial cross-sectional view along the BB direction.
[0111] like Figure 3 、 Figure 7 、 Figure 11 and Figure 12 As shown, in some embodiments, the reinforcing plate 23 can have a trumpet-shaped structure. From the inner edge of the reinforcing plate 23 toward its outer edge, the reinforcing plate 23 can be arranged to extend obliquely toward the cylinder rear wall 22. The trumpet-shaped, oblique extension structure of the reinforcing plate 23 can gradually reduce the thickness of the liquid counterweight chamber 25 from the outer peripheral edge of the bearing seat 221 toward the outer peripheral edge of the cylinder rear wall 22, gradually reduce the front-to-back width of the reinforcing rib 24 from the outer peripheral edge of the bearing seat 221 toward the outer peripheral edge of the cylinder rear wall 22, and gradually reduce the thickness of the bottom of the outer cylinder 2 from the center toward the outer peripheral edge, thereby facilitating a reduction in the bearing span of the cylinder rear wall 22 and increasing the internal volume of the outer cylinder 2.
[0112] In some embodiments, the annular center of the reinforcing plate 23 may be provided with an assembly hole 231. The reinforcing plate 23 can be mounted onto the front end of the bearing seat 221 through the assembly hole 231. Specifically, when the reinforcing plate 23 is fixed to the front side wall of the barrel rear wall 22, the front end of the bearing seat 221 can be embedded in the assembly hole 231 and exposed outside the accommodating cavity 20.
[0113] Figure 13 yes Figure 11 Partial cross-sectional view along CC direction. Figure 14 yes Figure 13 A local enlarged schematic diagram in .
[0114] like Figure 7 、 Figure 11 、 Figure 13 and Figure 14 As shown, in some embodiments, a pressure relief hole 232 may be formed on the reinforcing plate 23. A one-way pressure relief valve 233 may be embedded in the pressure relief hole 232. The liquid or gas in the liquid counterweight chamber 25 can overflow into the accommodating chamber 20 through the one-way pressure relief valve 233. In this way, when the liquid inlet 223 delivers excessive liquid into the liquid counterweight chamber 25, the pressure in the liquid counterweight chamber 25 increases, and the excess liquid can overflow into the accommodating chamber 20 through the one-way pressure relief valve 233, thereby ensuring the safety of the liquid counterweight chamber 25.
[0115] When the liquid (such as water) in the liquid counterweight chamber 25 is heated to generate steam, the pressure in the liquid counterweight chamber 25 increases, and the excess steam can overflow into the accommodating chamber 20 through the one-way pressure relief valve 233, ensuring the safety of the interior of the liquid counterweight chamber 25.
[0116] In some embodiments, the first detection portion 261 can be positioned at a lower height than the one-way pressure relief valve 233. The second detection portion 262 can also be positioned at a lower height than the one-way pressure relief valve 233. Thus, when the liquid in the liquid counterweight chamber 25 rises to a preset level, the preset level can be lower than the one-way pressure relief valve 233, allowing the one-way pressure relief valve 233 to be located in the gaseous space of the liquid counterweight chamber 25. When the liquid (e.g., water) in the liquid counterweight chamber 25 is heated to generate steam, the steam can be ensured to smoothly overflow from the one-way pressure relief valve 233 into the accommodating chamber 20.
[0117] like Figure 13 and Figure 14 As shown, in some embodiments, a pressure relief pipe 234 may be protruding from the back side of the reinforcement plate 23. A pressure relief hole 232 may be formed inside the pressure relief pipe 234. The pressure relief hole 232 may penetrate the pressure relief pipe 234. In this way, the one-way pressure relief valve 233 can be installed into the pressure relief hole 232 from the rear end of the pressure relief pipe 234. The one-way pressure relief valve 233 is fixed inside the pressure relief pipe 234, and then the one-way pressure relief valve 233 is embedded and fixed in the pressure relief hole 232.
[0118] In some embodiments, a limiting rib 2331 may be provided on the outer peripheral wall of the rear end of the one-way pressure relief valve 233. The limiting rib 2331 may be an annular structure. A limiting groove 2341 may be provided around the rear end of the pressure relief pipe 234. The limiting groove 2341 may be an annular structure. The limiting rib 2331 may be adapted to the limiting groove 2341. Thus, when the one-way pressure relief valve 233 is installed into the pressure relief hole 232 from the rear end of the pressure relief pipe 234, the limiting rib 2331 may be embedded in the limiting groove 2341 and abut against the limiting groove 2341, thereby preventing the one-way pressure relief valve 233 from excessively extending into the pressure relief hole 232 and preventing the front end of the one-way pressure relief valve 233 from protruding beyond the front side wall of the reinforcing plate 23.
