Description

Technical Field

[0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine which is only provided with a washing drum but not with an outer drum. Background Art

[0002] In the prior art, a drum washing machine generally includes an inner drum and an outer drum which are fitted together. The outer drum is sealed for holding water, and the inner drum is used to hold clothes. The clothes in the inner drum are beaten and washed by controlling the rotation of the inner drum. At the same time, a dehydration hole is provided on the inner drum, so that the water in the outer drum flows into the inner drum through the dehydration hole to soak the clothes in the inner drum. The water in the inner drum flows out to the outer drum through the dehydration hole, and the water on the clothes in the inner drum is discharged to the outer drum through the dehydration hole when the inner drum rotates at a high speed, so as to achieve the purpose of dehydrating the clothes after washing.

[0003] However, since the inner drum and the outer drum are nested in each other, dirt is easily accumulated between the inner and outer drums during the use of the washing machine; at the same time, since the inner and outer drums are nested in each other, the user cannot clean the outer wall of the inner drum and the inner wall of the outer drum, which increases the bacteria inside the washing machine, reduces the washing efficiency of the washing machine and the cleanliness of the clothes after washing.

[0004] At the same time, in the above-mentioned existing washing machines, since the outer drum is mounted outside the inner drum, the washing process of the washing machine is to wash the clothes by rotating the inner drum, so that the washing capacity of the washing machine is based on the inner drum, which makes the internal space utilization rate of the washing machine low and the washing capacity of the washing machine cannot be expanded on the existing basis.

[0005] In view of this, how to set up a washing machine to combine the inner and outer drums into one, so that the inner drum is set as a sealed container, which can not only hold water and clothes, but also rotate to beat the clothes for washing; at the same time, since the washing machine does not have an outer drum, or the outer drum is integrated with the washing machine shell, the inner drum of the washing machine can also be enlarged to expand the washing capacity of the washing machine, which has become a research and development hotspot.

[0006] In particular, since the washing drum formed by the inner drum is not only used to hold washing water, but also rotates to beat and wash the clothes in the drum, how to rotatably install the washing drum in the washing machine shell has become a difficult problem that needs to be solved urgently.

[0007] At the same time, since the washing drum not only rotates but also needs to take in and drain water, how to connect the washing drum that integrates the functions of inner and outer drums with the water inlet pipe, drain pipe and other components of the washing machine has become an urgent research and development issue that needs to be overcome.

[0008] In view of this, the present invention is proposed. Summary of the invention

[0086] In this embodiment, the washing tub 1 is divided into a first part 13 and a second part 14 along the axial direction, and the first part 13 and the second part 14 are coaxially plugged and connected so as to be relatively rotatable around the axis; a dynamic sealing assembly 15 is provided at the junction of the first part 13 and the second part 14; at least one first support ring 26 is sleeved on the outer periphery of the first part 13, and at least one second support ring 27 is sleeved on the outer periphery of the second part 14. By sleeved support rings on the outer peripheries of different parts of the washing tub, the two parts of the washing tub are supported respectively by different support rings, so as to achieve the effect that different parts of the washing tub can be relatively rotatable around the axis, thereby achieving the effect that part of the washing tub constitutes a rotatable part, and part is stationary and connected to the water inlet pipe, drain pipe and other components of the washing machine.

[0087] Preferably, in this embodiment, the connecting surface of the first part 13 and the second part 14 is perpendicular to the axis of the washing drum 1, so that the connecting surface of different parts of the washing drum is any radial cross-section of the washing drum, ensuring that the two parts can rotate around the axis.

[0088] In this embodiment, the first part 13 of the washing tub 1 includes the bottom 11 of the washing tub 1, and the second part 14 of the washing tub 1 includes the flange of the mouth of the washing tub 1; Figure 7 As shown, the second part 14 is provided with openings such as a drain port 19 and a water inlet which are connected to the outside, so that the second part 14 of the washing drum 1 is connected to the drain pipe of the washing machine through the drain port 19 and to the water inlet pipe of the washing machine through the water inlet, so that a part of the washing drum 1 close to the drum opening constitutes a static part, and the washing drum 1 with integrated inner and outer drum functions is connected to the water inlet pipe, water outlet pipe and other components of the washing machine, ensuring the purpose of normally executing the water intake, drainage and dehydration procedures.

[0089] In this embodiment, the first part 13 and the second part 14 of the washing tub 1 respectively include the front half and the rear half of the side wall 12, the front end of the first part 13 and the rear end of the second part 14 are correspondingly sleeved, and a bearing 18 is provided at the sleeve joint, the outer peripheral wall of the bearing 18 is in contact with the inner periphery of the second part 14, and the inner peripheral wall of the bearing 18 is in contact with the outer periphery of the first part. At the same time, in order to ensure the sealing of the joint between the two, a dynamic seal assembly 15 is provided on at least one side of the bearing 18, and the inner and outer peripheries of the dynamic seal assembly 15 are respectively sealed and connected with the first part 13 and the second part 14 to ensure the waterproofness of the joint between the first part and the second part.

[0090] In this embodiment, a first support ring 26 is provided on the outer periphery of the bottom 11 of the first part 13, and a drive motor 5 is provided on the first support ring 26. A plurality of connecting ribs 21 located on the rear side of the bottom 11 are provided at the rear end of the first support ring 26. The connecting ribs 21 extend in the axial direction of the washing tub 1 and are connected together at the axis to form a mounting portion 22. The mounting portion 22 is located on the rear side of the bottom 11 of the washing tub. The drive motor 5 is installed on the mounting portion 22. The motor shaft 51 of the drive motor 5 is coaxially connected to the bottom 11 of the first part 13 of the washing tub 1 to drive the first part 13 to rotate around the axis relative to the second part 14.

[0091] In this embodiment, the diameter of the second part 14 is larger than the diameter of the first part 13 to ensure that the lowest point of the washing drum is located on the second part 14, so that the washing water in the washing drum converges and flows toward the second part 14, ensuring that all the washing water in the washing drum 1 can be discharged, thereby achieving the purpose of the washing machine normally executing the drainage program.

[0092] Preferably, in the present embodiment, the first part 13 is a cone whose diameter gradually increases from the bottom 11 of the drum to the junction of the first part 13 and the second part 14, so that when the first part 13 rotates at a high speed to dehydrate the clothes in the drum, the washing water in the first part 13 is driven by centrifugal force to flow to the second part 14, so that the dehydrated water flow can be completely discharged through the drain pipe connected to the second part 14, thereby achieving the purpose of the washing machine normally executing the dehydration program (not indicated in the drawings).

[0093] In this embodiment, at least one circle of retaining ribs 16 protruding radially toward the axial direction of the washing tub 1 is provided at the junction of the first part 13 and the second part 14. By providing the retaining ribs, the clothes contained in the first part are prevented from flowing to the second part along with the drainage water flow, so that the clothes to be processed are always in the first part of the washing tub; at the same time, through the above arrangement, the clothes contained in the first part can enter the second part without being affected by centrifugal force, gravity, etc., ensuring that the clothes can be washed, dehydrated, etc. by the rotating first part.

[0094] At the same time, in this embodiment, in order to ensure that the washing water can flow between the first part 13 and the second part 14, the retaining rib 16 is provided with a leaking hole 17 for the washing water to pass through, so that the washing water can pass through the retaining rib 16 to achieve the effects of water intake, drainage, dehydration, etc. In this embodiment, the leaking hole 17 provided on the retaining rib 16 is located at the junction of the retaining rib 16 and the wall of the washing tub 1, so as to ensure that the water flowing to one side of the retaining rib 16 can all pass through the retaining rib 16 through the leaking hole 17, thereby ensuring the smooth drainage of the washing machine.

[0095] In this embodiment, the support ring 2 sleeved on the outer circumference of the second part 14 of the washing tub 1 is the second support ring 27. The groove 6 provided on the second support ring 27 is provided with separation ribs 61 arranged at intervals along the circumference of the washing tub. Each separation rib 61 divides the annular groove 6 into a plurality of arc grooves 62. The slider portion 7 radially protruding from the outer circumference of the second part 14 of the washing tub 1 is inserted into any arc groove 62 of the second support ring 27. By providing the separation rib 61 in the groove 6 on the second support ring 27, the second part 14 of the washing tub 1 can only generate a swing displacement of the distance between adjacent separation ribs 61, so that the second part 14 can be subjected to the friction of the first part 13 and swing in a small range, so as to reduce the torque stress at the connection between the two parts; and the second part 14 of the washing tub 1 can also constitute a non-rotating part, so as to achieve the effect of connecting with the water inlet pipe, drain pipe and other components of the washing machine. Of course, in this embodiment, in order to ensure the stability of the connection between the water inlet pipe, the drain pipe, etc. of the washing machine and the second part 14 of the washing drum 1, it is necessary to set at least part of the water inlet pipe, the drain pipe and other components as a bellows that can produce axial expansion and contraction, so as to ensure that the water inlet pipe, the drain pipe and other components will not fall off from each other due to the swinging of the second part.

[0096] In this embodiment, the distance between at least a portion of the partition rib 61 and the axis of the washing tub 1 is smaller than the distance between the slider portion 7 and the axis of the washing tub 1, so as to ensure that the second portion 14 of the washing tub 1 can be blocked by the partition rib 61 and confined within the single arc-shaped groove 62, so that the second portion 14 of the washing tub 1 can only produce a small range of relative swing displacement.

[0097] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
