Description

TECHNICAL FIELD

[0001] The present application relates to a washing machine, more particularly, a double drum washing machine. BACKGROUND

[0002] With the development of society and the increasing demand for the quality of life, the double drum laundry processing device is born in response to the development and needs of the times. It not only saves the space of the laundry processing device, but also provides more convenient laundry processing needs for users.

[0003] One of the important technical problems of the double drum laundry processing device is how to set the double drum. The previous conventional method is to set two drums in their respective frames, but there is a gap between the two drums, which not only occupies a lot of space, but also has a relatively large vibration noise during use.

[0004] Later, some technologies have improved this problem by connecting the two drums, which relatively reduces the space of the double drum laundry processing device and also reduces the noise to some extent. However, it still needs to install a balance adjusting device including a counterweight on the outer drum, which not only increases the cost of the washing machine, but also has no obvious effect on shock absorption and noise reduction. Moreover, the elements connecting the double drums are separately arranged, which not only makes the installation complicated, but also is easily affected by the long-term running process of the double drum laundry processing device, causing problems such as falling off and poor stability.

[0005] In addition, since the inner drum and the outer drum are mutually installed, dirt is easily accumulated between the inner and outer drums during use of the washing machine. At the same time, since the inner and outer drums are mutually installed, the user cannot clean the outer wall of the inner drum and the inner wall of the outer drum, which increases the bacteria in the washing machine and reduces the washing efficiency and cleanliness of the laundry after washing. At the same time, the washing process of the washing machine is to tumble and wash the laundry by rotating the inner drum, so that the washing capacity of the washing machine is based on the inner drum, which makes the utilization rate of the internal space of the washing machine lower and cannot expand the washing capacity of the washing machine on the basis of the existing washing machine. If such laundry is left for a long time, dirt will adhere to the laundry, causing the problem that the dirt cannot be completely removed.

[0006] Therefore, the present application is proposed. SUMMARY

[0036] As shown in Figures 1 to 4 The embodiments of the present application introduce a double-drum washing machine, which comprises a support frame 100, the support frame 100 is surrounded by a shell surrounding the outer side thereof to form an outer shell, a first washing unit 1 and a second washing unit 2 are arranged in a stacked manner inside the outer shell, and the first washing unit 1 and the second washing unit 2 are respectively mounted on the support frame 100 by springs and / or damping members. The first washing unit 1 and the second washing unit 2 can simultaneously have clothes washing and drying functions. Preferably, in the embodiments of the present application, the first washing unit 1 and the second washing unit 2 arranged above simultaneously have washing and drying functions.

[0037] Embodiment one

[0038] As Figure 2 shown, the double drum washing machine comprises a washing machine support frame 100, a first washing unit 1 and a second washing unit 2 installed in the support frame 100, and a first inner drum 7 and a second outer drum 10 arranged in the first washing unit 1 and the second washing unit 2 respectively. In the embodiment, the first washing unit 1 comprises the first inner drum 7 capable of independently containing washing water, and the second washing unit 2 comprises the coaxially arranged second outer drum 10 and second inner drum 8. Through the above arrangement, the washing capacity of the inner drum is increased. In the embodiment, the capacity of the first inner drum 7 is smaller than that of the second inner drum 8. Preferably, the first washing unit 1 is arranged with the inner drum capable of independently containing washing water, i.e., the first inner drum 7 is capable of independently containing washing water. In this way, the effective washing space of the double drum washing machine is larger.

[0039] In the embodiment, the front and rear ends of the first washing unit 1 and the second washing unit 2 are connected through a support assembly 3. The support assembly 3 is detachably installed on the first washing unit 1. Through the arrangement of the support assembly 3 between the first washing unit 1 and the second washing unit 2, the two washing units are integrally connected to realize the double drum washing machine sharing the counterweight. In addition, the placement gap of the first inner drum 7 and the second outer drum 10 can be fully utilized without occupying additional space, so that the structure of the double drum washing machine is more compact, and the vibration noise is reduced.

[0040] As Figure 3 shown, the support assembly 3 comprises a front and rear extending connecting support 31, a front connecting piece 32 and a rear support 33. The connecting support 31 is provided with a protruding connecting block 9 at the front and rear ends respectively. The connecting block 9 is provided with a mounting hole 91. The end faces of the connecting block 9 are attached to the front connecting piece 32 and the rear support 33 respectively. Screws pass through the mounting hole 91 to connect the connecting support 31, the front connecting piece 32 and the rear support 33. The two ends of the connecting support 31 are respectively bent by a certain angle, so that the connecting support 31 has a U-shaped structure. The length of the gap of the connecting support 31 is equal to the axial length of the first inner drum 7, so that the front end and the rear end of the first inner drum 7 can be smoothly placed in the gap. Preferably, the connecting support 31 is arranged in relative inclination.

The support assembly 3 further includes the rear connecting piece 35, which is detachably mounted on one side of the support end 34. The rear connecting piece 35 is provided with a protruding support end, and the support end is provided with a mounting through hole. The rear connecting piece 35 is fixedly mounted on the rear support 33. The rear support 33 is coaxially arranged with the first inner cylinder 7, and the support end is connected to the second outer cylinder 10. Thus, the first inner cylinder 7 and the second outer cylinder 10 are fixedly connected and regarded as a whole, so that no additional counterweight is arranged, the components are reduced, the cost is reduced, the components are less, the probability of failure is lower, and the stability of the overall structure is improved.

[0043] As shown in Figures 2 to 4 In the embodiment of the present application, the front connecting piece 32 includes an arc-shaped structure at the upper portion and left and right support ends arranged at the lower portion of the arc-shaped structure. The left and right support ends are arranged at different height positions, and the two end portions of the arc-shaped structure and the left and right support ends are provided with mounting through holes. The two end portions of the arc-shaped structure are provided with through holes, and screws pass through the through holes and the mounting holes 91 on the connecting block 9 in sequence to fixedly connect the front connecting piece 32 and the connecting support 31.

[0044] The arc-shaped structure at the upper portion of the front connecting piece 32 is used for abutting against the first inner cylinder 7, and the lower half is connected to the front portion of the second outer cylinder 10. The inner concave surface of the arc-shaped structure matches the outer contour of the first inner cylinder 7, and the front portion of the second outer cylinder 10 is provided with bolt columns corresponding to the mounting through holes of the left and right support ends.

[0045] In the embodiment, the front end and the rear end of the second outer cylinder 10 are provided with a connecting part 4 protruding from the surface, the connecting part 4 is arranged in the axial direction of the second outer cylinder 10, the structure of the connecting part 4 is more firm and reliable, the connection of the second outer cylinder 10 is more stable, the connecting part 4 is connected with the front connecting part 32 and the rear connecting part 35 respectively, and the installation is facilitated.

[0046] The connecting part 4 is a bolt column integrally formed at the front end and the rear end of the second outer cylinder 10, the front end bolt column penetrates the front connecting part 32, and the rear end bolt column penetrates the mounting through hole of the rear connecting part 35. The bolt column is provided with a hollow structure, the bolt column penetrates the mounting through hole, and the screw is connected and fixed with the hollow structure through a gasket, so as to fix and connect the first inner cylinder 7 and the second outer cylinder 10.

[0047] As shown in Figure 3 In the embodiment, the water collecting device 5 coaxially sleeved with the first inner cylinder 7 has an accommodating chamber open to the side of the first inner cylinder 7, and the first inner cylinder 7 is arranged in the accommodating chamber. A water collecting groove 6 is arranged on the bottom wall of the accommodating chamber, and the discharged water flow of the first inner cylinder 7 is discharged into the water collecting groove 6. The discharged water flow of the first inner cylinder 7 can be collected in the water collecting recess, the spatter of the discharged water flow to the wall surface of the first inner cylinder 7 is reduced, and the discharge efficiency of the discharged water flow is improved under the collection of the water collecting groove 6. The first inner cylinder 7 is arranged on the support assembly 3, and the water collecting groove 6 is located in the middle of the connecting support 31, so that the space occupation volume is reduced and the layout is more reasonable.

[0048] Embodiment two

[0049] As shown in Figure 1 In the embodiment, a double drum washing machine is introduced, and the difference between the embodiment and the above-mentioned embodiment is that the first washing unit 1 and the second washing unit 2 of the double drum washing machine are respectively provided with the first inner cylinder 7 and the second inner cylinder 8 which can independently contain washing water, so that the effective washing area of the double drum washing machine is larger. In addition, the mounting mode of the second inner cylinder 8 is different from the existing mounting mode, the rear end of the second inner cylinder 8 is additionally provided with the rear support 33 coaxially arranged as introduced in the first embodiment, but the rear support 33 coaxially arranged with the second inner cylinder 8 does not have the support end part 34 in the embodiment, the first inner cylinder 7 and the second inner cylinder 8 are arranged on different support assemblies 3, and the second inner cylinder 8 is a conical cylinder with one end having a large diameter and the other end having a small diameter, so that the washing space of the original outer cylinder washing machine can be effectively increased.

[0050] Embodiment three

[0051] The embodiment of the present application is different from the first embodiment in that the second inner drum 8 is coaxially sleeved with a water collecting device 5, and the water collecting device 5 has an accommodating chamber which is open to one end. Preferably, the capacity of the second inner drum 8 is larger than that of the first inner drum 7. In this way, when the double drum washing machine is working, the double drum washing machine is more stable as a whole due to the heavier weight of the second inner drum 8 and the location of the second inner drum 8 at the lower end of the double drum washing machine.

[0052] The water collecting device 5 comprises a bottom wall and a side wall. The bottom wall is coaxially arranged with the second inner drum 8 and arranged at the rear of the second inner drum 8. The side wall is arranged at the edge of the bottom wall and extends towards the second inner drum 8 and annularly arranged outside the second inner drum 8. The extension length of the side wall is specifically set according to the position of the water outlet. Preferably, the water outlet is arranged within the surrounding range of the side wall. Arranging the water outlet within the surrounding range of the side wall can effectively block the discharged water flow in the second inner drum 8 and prevent the discharged water flow from splashing on the wall surface of the second inner drum 8.

[0053] The water collecting groove 6 is recessed away from the second inner drum 8 and annularly arranged on the bottom wall. The water collecting groove 6 comprises a first side wall, a second side wall and a groove bottom wall.

[0054] As another scheme in the embodiment, the first side wall is connected with the edge of the bottom wall of the water collecting device 5 and extends away from the second inner drum 8. The second side wall is connected with the side wall of the water collecting device 5 and extends towards the second inner drum 8. The groove bottom wall is connected with the first side wall and the second side wall respectively. In this scheme, the water collecting groove 6 is integrally formed and fixedly connected with the bottom wall and the side wall of the water collecting device 5 as an independent component. As an independent component, the water collecting groove 6 is fixedly connected with the water collecting device 5, which is simple to process and is especially beneficial to cleaning and repairing the water collecting groove 6 later when the water collecting groove 6 is detachably fixedly connected with the water collecting device 5.

[0055] The water collecting groove 6 and the water collecting device 5 can be connected by welding, screwing, riveting or inserting.

[0056] In the embodiment of the present application, the first inner drum 7 and the second inner drum 8 are integrally installed through the support assembly 3. The support assembly 3 is installed at the front and rear ends of the first inner drum 7. The water collecting groove 6 is located between the connecting supports 31 of the support assembly 3. In this way, the gap space of the double drum washing machine can be better utilized and the effective washing space of the double drum washing machine can be improved.

[0057] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application, and any person skilled in the art can make some changes or modifications to the above-mentioned technical content with equivalent embodiments within the scope of the technical solutions of the present application. The embodiments in the above-mentioned embodiments can be further combined or replaced, as long as they do not deviate from the technical solutions of the present application.
