[0029] The washing machine is a cleaning electric appliance that uses electric energy to produce mechanical action to wash clothes. It is a commonly used clothes processing device. The washing machine can free the user's hands, wash a large amount of clothes at a time, save the user's time and effort in doing housework, and bring great convenience to the user. With the development of the washing machine industry technology, the washing mode of the washing machine is more and more diversified, and the demand of users for the double-cylinder washing machine with washing function in each cylinder is increasing.

[0030] In the related art, the double-cylinder washing machine includes an upper cylinder and a lower cylinder, and the upper cylinder and the lower cylinder are composed of an outer cylinder and an inner cylinder. In assembly, in order to provide stable support for the upper cylinder, a connecting piece is generally arranged between the upper outer cylinder and the lower outer cylinder. However, in the assembly of the existing washing machine, the connecting piece needs to be connected and fixed with the upper outer cylinder and the lower outer cylinder through fasteners respectively, and the assembly is very troublesome.

[0031] Based on the above situation, please refer to Figures 1-6The embodiment of the present application provides a clothes processing device, which comprises a first shell, the first shell comprises a first outer cylinder 100, a second outer cylinder 200 and a connecting piece 400, the first outer cylinder 100 comprises a first cylinder body 110 and a first cover 120, the first cover 120 is arranged at one end of the first cylinder body 110, the first cylinder body 110 is provided with a first opening at the end away from the first cover 120, the second outer cylinder 200 comprises a second cylinder body 210 and a second cover 220, the second cover 220 is arranged at one end of the second cylinder body 210, the second cylinder body 210 is provided with a second opening at the end away from the second cover 220, the first opening and the second opening are located at opposite sides of the first shell, the connecting piece 400 connects the first outer cylinder 100 and the second outer cylinder 200, and the first outer cylinder 100, the connecting piece 400 and the second outer cylinder 200 are integrally formed.

[0032] It should be noted that the inner cavity of the first cylinder body 110 is used for assembling the upper inner cylinder 500, the first opening is an entrance for the upper inner cylinder 500 to be installed in the first cylinder body 110, and the direction from the first end of the first cylinder body 110 to the second end is opposite to the direction from the first end of the second cylinder body 210 to the second end, that is, the first cover 120 and the second cover 220 are arranged on different sides, so that the upper inner cylinder 500 and the lower inner cylinder 600 can be installed in the first outer cylinder 100 and the second outer cylinder 200 in different installation directions respectively, the upper inner cylinder 500 and the lower inner cylinder 600 can be well avoided during assembly, and the problem of interference between the upper inner cylinder 500 and the lower inner cylinder 600 during assembly can be avoided, thereby indirectly improving the assembly efficiency of the whole washing machine. Figure 1 For the convenience of description, the first opening is located at the front side of the first outer cylinder 100, the second opening is located at the rear side of the second outer cylinder 200, that is, the first cover 120 is the rear cover of the first outer cylinder 100, and the second cover 220 is the front cover of the second outer cylinder 200.

[0033] Effects of the present application: (1) The laundry treatment equipment integrates the first outer cylinder 100, the second outer cylinder 200, and the connecting piece 400 connecting the first outer cylinder 100 and the second outer cylinder 200, which not only saves the trouble of connecting the connecting piece 400 to the first outer cylinder 100 or the second outer cylinder 200 through fasteners during assembly, thereby improving the assembly efficiency of the entire washing machine, but also after assembly, the weight of the first outer cylinder 100 can act as the counterweight of the second outer cylinder 200, and the weight of the second outer cylinder 200 can act as the counterweight of the first outer cylinder 100, so that the first outer cylinder 100 and the second outer cylinder 200 can be counterweighted, achieving the effect of system dynamic balance with a smaller weight balance block; (2) By setting the first cover 120 of the first outer cylinder 100 and the second cover 220 of the second outer cylinder 200 on different sides, the upper inner cylinder 500 and the lower inner cylinder 600 can be well avoided during assembly, which is beneficial to avoid the problem of interference between the upper inner cylinder 500 and the lower inner cylinder 600 during assembly, thereby indirectly improving the assembly efficiency of the entire washing machine; (3) The processing technology of the outer cylinder of the washing machine can be simplified, avoiding separate processing of each part, and the fasteners required when connecting the first outer cylinder 100 and the second outer cylinder 200 of the existing washing machine can be reduced.

[0034] Please refer to Figures 1 to 3 The laundry treatment equipment further comprises a third outer cylinder 300, the third outer cylinder 300 comprising a third cylinder body 310 and a third cover 320, the third cover 320 being arranged at one end of the third cylinder body 310, and the third cylinder body 310 being provided with a third through port at an end away from the third cover 320, the second outer cylinder 200 being connected with the third outer cylinder 300, and the second through port and the third through port being in communication, so that the second outer cylinder 200 and the third outer cylinder 300 jointly enclose an inner cylinder accommodating cavity, and the second cover 220 is provided with an opening 221 in communication with the inner cylinder accommodating cavity and the external environment. The third outer cylinder 300 can be arranged together with the second outer cylinder 200 to form a cylinder body for assembling the lower inner cylinder 600, the third through port being an entrance for the lower inner cylinder 600 to be installed in the second outer cylinder 200, and the second outer cylinder 200 and the third outer cylinder 300 being in abutting cooperation to provide a position for installing the lower inner cylinder 600, and also forming a wrapping protection effect for the lower inner cylinder 600, so that the lower inner cylinder 600 can work in a stable supporting environment. In addition, please refer to Figures 1 to 3When the length of the second outer cylinder 200 is less than the length of the third outer cylinder 300, the center of gravity of the lower cylinder body composed of the second outer cylinder 200, the third outer cylinder 300 and the lower inner cylinder 600 falls on the third outer cylinder 300, and the first cover 120 is closer to the center of gravity of the lower cylinder body than the cover arranged at the end of the first cylinder body 110 away from the first cover 120 (assuming that the first outer cylinder 100 is provided with a front cover and is not provided with a rear cover, because the first outer cylinder 100 is provided with an opening at least at one end for mounting the upper inner cylinder 500), that is, the center of gravity of the upper cylinder body composed of the first outer cylinder 100 and the upper inner cylinder 500 is closer to the center of gravity of the lower cylinder body, so that the counterweight effect between the upper cylinder body and the lower cylinder body is better.

[0035] It should be noted that the second outer cylinder 200 and the third outer cylinder 300 can be connected by a plurality of fasteners, and a sealing member is arranged between the second outer cylinder 200 and the third outer cylinder 300 to ensure the sealing of the connection between the second outer cylinder 200 and the third outer cylinder 300, so as to avoid the leakage of the washing machine. Please refer to Figure 1 The opening 221 arranged on the second outer cylinder 200 can expose the laundry of the lower inner cylinder 600, so that the user can put the laundry into the lower inner cylinder 600 through the opening 221 of the second outer cylinder 200 for cleaning.

[0036] Please refer to Figure 6 The laundry treating apparatus further comprises an upper inner cylinder 500 and a lower inner cylinder 600. The upper inner cylinder 500 is arranged in the first outer cylinder 100, and the lower inner cylinder 600 is arranged in the inner cylinder accommodating cavity. Part of the lower inner cylinder 600 is located in the second outer cylinder 200, and part of the lower inner cylinder 600 is located in the third outer cylinder 300. For the convenience of understanding, taking the first opening located at the front side of the first outer cylinder 100, the second opening located at the rear side of the second outer cylinder 200, and the third opening located at the front side of the third outer cylinder 300 as an example, when assembling, part of the lower inner cylinder 600 is first mounted in the third outer cylinder 300 through the third opening, and then the remaining part of the lower inner cylinder 600 is mounted in the second outer cylinder 200 from back to front through the second opening by the relative movement of the second outer cylinder 200 and the third outer cylinder 300, so as to realize the assembly of the entire lower inner cylinder 600 in the inner cylinder accommodating cavity. The upper inner cylinder 500 can be mounted in the first outer cylinder 100 from front to back through the first opening, and the installation of the upper inner cylinder 500 is not affected by the installation of the lower inner cylinder 600, that is, the upper inner cylinder 500 and the lower inner cylinder 600 do not interfere with each other during installation, which greatly reduces the interference factors caused by the simultaneous assembly of the upper inner cylinder 500 and the lower inner cylinder 600 on the rack 700.

[0037] It should be noted that the upper inner drum 500 and the lower inner drum 600 both refer to the drum body for participating in the washing of laundry, and the driving assembly or other components required for the movement of the upper inner drum 500 and the lower inner drum 600 can be installed after the upper inner drum 500 is assembled in the first outer drum 100 or the lower inner drum 600 is assembled in the inner drum accommodating cavity. The driving assembly can be, but is not limited to, a motor.

[0038] Referring to Figure 1 , the inner wall of the first drum body 110 is formed with a first drain groove 111 in communication with the inner cavity of the first outer drum 100, and the first cover 120 or the first drum body 110 is provided with a first drain portion in communication with the first drain groove 111 and the external environment. When the upper inner drum 500 is assembled in the inner cavity of the first outer drum 100, the sewage generated by the upper inner drum 500 for washing laundry will be transported to the inner cavity of the first outer drum 100. The first drain groove 111 is arranged at the lowest part of the inner cavity of the first outer drum 100, so that the sewage can be collected in the first drain groove 111 and discharged out of the body through the first drain portion, realizing the required drainage function of the upper inner drum 500 after washing laundry.

[0039] Referring to Figures 1 to 3 , the inner wall of the third drum body 310 or between the second drum body 210 and the third drum body 310 is formed with a second drain groove 311 in communication with the inner drum accommodating cavity. The third cover 320 or the third drum body 310 is provided with a second drain portion in communication with the second drain groove 311 and the external environment. When the lower inner drum 600 is assembled in the inner drum accommodating cavity, the sewage generated by the lower inner drum 600 for washing laundry will be transported to the inner drum accommodating cavity. The second drain groove 311 is arranged at the lowest part of the inner drum accommodating cavity, so that the sewage can be collected in the second drain groove 311 and discharged out of the body through the second drain portion, realizing the required drainage function of the lower inner drum 600 after washing laundry.

[0040] It should be noted that the second drain groove 311 can be arranged on the inner wall of the third drum body 310, so that the sewage can be discharged out of the body through the second drain portion; the second drain groove 311 can also be partially arranged on the inner wall of the third drum body 310, and the other part is arranged on the inner wall of the second drum body 210. When the second outer drum 200 and the third outer drum 300 are connected by cooperation, the grooves on the inner walls of the two can jointly form a complete second drain groove 311, which can also discharge the sewage out of the body through the second drain portion.

[0041] In an embodiment, the second outer drum 200 and the third outer drum 300 jointly constitute a lower outer drum, and the volume of the first outer drum 100 is smaller than the volume of the lower outer drum. In this way, the second outer drum 200 can on the one hand vacate the installation position of other components of the washing machine, such as the drying assembly, so that the internal structure of the entire washing machine can be more compact when assembled, which is beneficial to improve the space utilization, and on the other hand, the center of gravity of the first outer drum 100 can be closer to the front cover of the second outer drum 200, so that the weight of the first outer drum 100 can more easily act as a counterweight of the second outer drum 200, and the weight of the second outer drum 200 can act as a counterweight of the first outer drum 100, which is beneficial to reduce the use of the counterweight block 800.

[0042] It should be noted that the first outer drum 100 and the upper inner drum 500 jointly serving as the upper drum body with a smaller washing capacity can be more suitable (but not limited to) for washing small or light clothes, such as washing clothes for infants, while the second outer drum 200, the third outer drum 300 and the lower inner drum 600 jointly serving as the lower drum body with a larger washing capacity can be more suitable (but not limited to) for washing large or heavy clothes, such as washing clothes for adults, so as to meet the user's selection of different drum bodies for washing clothes according to different clothes, which is beneficial to improve the applicability of the entire washing machine and expand the use scenarios of the entire washing machine to meet the different use requirements of different users.

[0043] In an embodiment, under the premise that the volume of the first outer drum 100 is smaller than the volume of the lower outer drum and the first outer drum 100 is arranged on one side above the lower outer drum, the ratio of the length of the second outer drum 200 to the total length of the lower outer drum is 1:3 to 1:2. The length of the second outer drum 200 should not be too long, otherwise the center of gravity of the integrated structure jointly constituted by the first outer drum 100, the connecting piece 400 and the second outer drum 200 will move towards the third outer drum 300, which will weaken the counterweight effect of the second outer drum 200 and the first outer drum 100, resulting in an increase in the weight of the counterweight block 800 required by the second outer drum 200; the length of the second outer drum 200 should also not be too short, otherwise there will be not enough place for the second outer drum 200 and the third outer drum 300 to be abutted and matched, and the weight of the second outer drum 200 itself will also decrease, which will also affect the counterweight effect with the first outer drum 100.

[0044] It should be noted that the specific length of the second outer drum 200 can be designed with reference to the length of the first outer drum 100, and as an optional embodiment, when the length of the first outer drum 100 is less than 1 / 2 of the total length of the lower outer drum, the length of the second outer drum 200 is 1 / 3 of the total length of the lower outer drum.

[0045] Please refer to Figures 4-6, the laundry treating apparatus further comprises a frame 700, the first outer tub 100, the second outer tub 200 and the third outer tub 300 are arranged in the frame 700, the first outer tub 100 and the second outer tub 200 are arranged in parallel in the vertical direction, the first outer tub 100 is above the second outer tub 200, and the second outer tub 200 and the third outer tub 300 are arranged in parallel in the horizontal direction. In this way, after the first outer tub 100, the second outer tub 200 and the third outer tub 300 are installed in the frame 700, the first through hole of the first outer tub 100 and the third through hole of the third outer tub 300 are in the same direction, that is, the direction in which the first outer tub 100 can accommodate the upper inner tub 500 is the same as the direction in which the third outer tub 300 can accommodate the lower inner tub 600, so that during assembly, the frame 700 only needs to leave one side to meet the accommodation of the upper inner tub 500 and the lower inner tub 600, without the need to disassemble the support on the other side of the frame 700, while ensuring that the first outer tub 100, the second outer tub 200 and the third outer tub 300 can be compactly installed in the frame 700, the upper inner tub 500 and the lower inner tub 600 can also be installed at the same entrance position, which is conducive to reducing the assembly difficulty and indirectly improving the assembly efficiency of the washing machine.

[0046] In an embodiment, the laundry treating apparatus further comprises a drying assembly (not shown in the figure), which is arranged in the frame 700; the drying assembly is arranged above the third outer tub 300 and on the side of the first cover 120 away from the first tub body 110. The drying assembly comprises components such as a heat pump, a condenser and an evaporator, and the arrangement of the drying assembly can meet the requirement that the washing machine can dry the washed clothes, and by arranging the first outer tub 100, the second outer tub 200, the third outer tub 300 and the drying assembly at the left upper position, the left lower position, the right lower position and the right upper position in the frame 700 respectively, the installation positions of the components can be better distributed from top to bottom and left to right, so that the internal structure of the frame 700 is more compact, which can not only improve the space utilization of the frame 700, make the assembly more simple and reasonable, but also make the internal structure of the entire washing machine more compact, which is conducive to reducing the overall size of the washing machine and meeting the user's requirement for light and small design of the washing machine.

[0047] In an embodiment, please refer to Figures 4-6 , the laundry treating apparatus further comprises a counterweight 800, which is arranged in the second outer tub 200, and the counterweight 800 is on the side of the second cover 220 away from the second tub body 210. The arrangement of the counterweight 800 can make the counterweight of the first outer tub 100 and the second outer tub 200 more balanced, and because the entire machine will vibrate when the inner tub of the washing machine rotates at high speed, the arrangement of the counterweight 800 can avoid that the overall structure of the outer tub of the washing machine is too light, effectively reducing the vibration and noise generated when the inner tub of the washing machine rotates. Please refer toFigure 1 、 Figure 4 , the first outer cylinder 100 is an upper outer cylinder, the upper outer cylinder and the upper inner cylinder 500 jointly form an upper cylinder body, the second outer cylinder 200 and the third outer cylinder 300 jointly form a lower outer cylinder, the upper outer cylinder is shorter, and the lower outer cylinder is longer, the second outer cylinder 200, the third outer cylinder 300 and the lower inner cylinder 600 jointly form a lower cylinder body. The center of gravity of the upper cylinder body is located above the second outer cylinder 200, the third outer cylinder 300 is longer than the second outer cylinder 200, and the center of gravity of the lower cylinder body is located at a rear position without considering the weight of the upper cylinder body counterweight and the counterweight 800. Based on the integrated forming of the first outer cylinder 100, the connecting piece 400 and the second outer cylinder 200, the counterweight 800 arranged on the front side of the second outer cylinder 200 can serve as the counterweight of the upper cylinder body when the upper inner cylinder 500 rotates and the first outer cylinder 100 has a tendency to sway, thereby reducing the degree of swaying of the first outer cylinder 100 during operation of the upper cylinder body. When the lower inner cylinder 600 rotates and the second outer cylinder 200 and the third outer cylinder 300 have a tendency to sway, the swaying caused by the clothes in the lower inner cylinder 600 is constrained by the counterweight 800 on the front side of the second outer cylinder 200 and the counterweight of the upper cylinder body, thereby maintaining the stability of the lower outer cylinder and reducing the degree of swaying of the second outer cylinder 200 and the third outer cylinder 300 during operation of the lower cylinder body. In other words, by arranging the counterweight 800 on the front side of the second outer cylinder 200, the same set of counterweights 800 can be used to balance the counterweight effect of the upper cylinder body and the lower cylinder body, and the overall structure is more compact.

[0048] In another embodiment, the counterweight 800 can also be arranged on the connecting piece 400, and the counterweight 800 is located on the front side of the connecting piece 400, which can also have the effect of balancing the counterweight of the first outer cylinder 100 and the second outer cylinder 200.
