Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of washing machine components, in particular to a water containing structure of a washing machine without an outer drum and the washing machine. BACKGROUND

[0002] The pulsator washing machine adopts the form of combination of inner and outer drums to achieve washing and dewatering functions. The water between the inner and outer drums and the water between the inner drum and the outer drum flow through the dewatering holes on the inner drum. The space between the inner and outer drums is in a humid state for a long time, which is easy to breed bacteria and produce dirt. The washing machine without an outer drum cancels the outer drum on the basis of the structure of the traditional washing machine, which solves the problem of secondary pollution of clothes caused by residual stains and bacteria breeding in the outer drum. The water in the water containing support part is relatively small, which reduces the water consumption of the washing machine.

[0003] However, the existing washing machine without an outer drum has the following problems. The inner drum bottom end rotates to clean clothes, which is easy to cause water seepage of the inner drum. The water seeped out of the inner drum seeps down through the gap at the bottom end of the inner drum of the washing machine, which damages the parts of the washing machine. For example, in the patent CN114645401A, a washing machine without an outer drum is disclosed, which comprises a balance ring and an inner drum. The balance ring forms a first water passing channel, and the first water passing channel is provided with a first water inlet and a first water outlet. The first water passing channel is formed with a first flow guide surface and a second flow guide surface. One end of the first flow guide surface is connected to one end of the second flow guide surface. The other end of the first flow guide surface extends to the first water inlet. The other end of the second flow guide surface extends to the first water outlet. The connection part of the first flow guide surface and the second flow guide surface is higher than the first water inlet and the first water outlet. The inner drum is provided with a second water passing channel, and the second water passing channel is formed with a second water inlet and a second water outlet. The first water outlet is in communication with the second water inlet. SUMMARY

[0030] The sealing structure 3 comprises an ear-shaped sealing oil groove 303 and a curved extension 301, both of which are arranged in an annular structure, a fastening spring 304 arranged in the outer groove of the ear-shaped sealing oil groove 303, and a water absorption expansion assembly arranged in the groove between the ear-shaped sealing oil groove 303 and the curved extension 301.

[0031] Specifically, when the washing machine is washing clothes, the speed reducer 5 drives the washing machine inner drum 1 and the rotating flange 4 to rotate, because the side wall of the washing machine inner drum 1 is a non-porous cylinder wall, a certain amount of water is contained in the washing machine inner drum 1 to clean the clothes; when draining, the waste water is drained through the drain valve 6 at the bottom end of the washing machine inner drum 1 connected to the drain pipe. When the washing machine inner drum 1 is filled with water to wash clothes, in order to prevent the water in the washing machine inner drum 1 from seeping through the gap between the bottom end of the washing machine inner drum 1 and the rotating flange 4 and flowing to the speed reducer 5, damaging the washing machine parts, the water containing support 2 and the sealing structure 3 are arranged to prevent the water in the washing machine inner drum 1 from seeping.

[0032] When the rotating flange 4 rotates, the sealing structure 3 seals the gap between the rotating flange 4 and the water containing support 2, the ear-shaped sealing oil groove 303 contains a certain amount of oil, which ensures the stable rotation of the rotating flange 4, and the fastening spring 304 makes the ear-shaped sealing oil groove 303 better fit the rotating flange 4.

[0033] At the same time, the water absorption expansion assembly absorbs water and expands, and extrudes the outer side of the ear-shaped sealing oil groove 303 through the water absorption expansion assembly, so that the ear-shaped sealing oil groove 303 better fits the rotating flange 4, avoiding water seepage.

[0034] In one embodiment of the present application, the water absorption expansion assembly comprises a water absorption resin 9 and an extrusion push plate 8, the water absorption resin 9 is arranged in the groove between the ear-shaped sealing oil groove 303 and the curved extension 301, one side of the water absorption resin 9 is provided with the extrusion push plate 8, and the extrusion push plate 8 is located on one side of the fastening spring 304.

[0035] Specifically, the water absorption resin 9 absorbs water and expands, and extrudes the outer side of the ear-shaped sealing oil groove 303 through the extrusion push plate 8, so that the ear-shaped sealing oil groove 303 better fits the rotating flange 4, avoiding water seepage.

[0036] In one embodiment of the present application, the area surrounded by the top recess of the ear-shaped sealing oil groove 303 and the outer side of the rotating flange 4 is an oil infiltration groove 305.

[0037] In one of the embodiments of the present application, the top end of the curved extension 301 is attached with a sealing ring positioning piece 7, the bottom end of the curved extension 301 is provided with a sawtooth fixing block 302 at the clamping position of the water containing support 2, and an oil injection mechanism is arranged in the top end groove of the sealing ring positioning piece 7.

[0038] Specifically, the sealing ring positioning piece 7 reinforces the structure of the curved extension 301, and the sawtooth fixing block 302 is coated with glue, so that the curved extension 301 is combined with the water containing support 2 more firmly and tightly.

[0039] In one of the embodiments of the present application, the oil injection mechanism comprises an oil storage box 12, a transmission pipe 13 and an oil outlet nozzle 14, and the oil storage box 12 is provided with a squeezing mechanism on both sides.

[0040] Specifically, the squeezing mechanism squeezes the side of the oil storage box 12 at the same time, so that the oil is more easily squeezed out.

[0041] In one of the embodiments of the present application, the top end of the oil storage box 12 is connected with the transmission pipe 13, the end of the transmission pipe 13 extends to the top end of the ear-shaped sealing oil groove 303, the end of the transmission pipe 13 is provided with the oil outlet nozzle 14, and the oil outlet nozzle 14 is located above the oil infiltration groove 305.

[0042] Specifically, the oil drops into the oil infiltration groove 305, slowly penetrates into the ear-shaped sealing oil groove 303 through the gap between the bottom end of the oil infiltration groove 305 and the rotating flange 4, and strengthens the lubricating effect between the ear-shaped sealing oil groove 303 and the rotating flange 4.

[0043] In one of the embodiments of the present application, the squeezing mechanism comprises a hole cylinder 11, a water-absorbing and expanding rubber 10 and a squeezing block 15, the hole cylinder 11 is internally provided with the water-absorbing and expanding rubber 10, one side of the water-absorbing and expanding rubber 10 is provided with the squeezing block 15, the squeezing block 15 is in sliding connection with the inside of the hole cylinder 11, the squeezing block 15 abuts against one side of the oil storage box 12, and a plurality of through holes are formed in the side wall of the hole cylinder 11.

[0044] Specifically, if a small amount of liquid drops seep out from the gap between the bottom end of the washing machine inner barrel 1 and the rotating flange 4, the water flows to the sealing structure 3, the water-absorbing and expanding rubber 10 in the hole cylinder 11 absorbs water and expands, and pushes the squeezing block 15 to move, the squeezing block 15 squeezes the oil storage box 12 on both sides, so that the oil in the oil storage box 12 flows out to the transmission pipe 13, and then flows to the oil outlet nozzle 14 through the transmission pipe 13, the oil drops into the oil infiltration groove 305, and then penetrates into the ear-shaped sealing oil groove 303, thereby strengthening the lubricating effect between the ear-shaped sealing oil groove 303 and the rotating flange 4.

[0045] In one embodiment of the present application, the side wall of the washing machine inner drum 1 is a non-porous cylinder wall. The inside of the washing machine inner drum 1 can hold water to clean clothes.

[0046] In one embodiment of the present application, the inner drum assembly further comprises a drain valve 6 located at the bottom end of the washing machine inner drum 1.

[0047] In another aspect, the present application also provides a washing machine, wherein the washing machine housing is provided with the above-mentioned water holding structure of the non-outer drum washing machine.

[0048] The working principle of the present application is as follows: when the washing machine is cleaning clothes, the speed reducer 5 drives the washing machine inner drum 1 and the rotating flange 4 to rotate. Since the side wall of the washing machine inner drum 1 is a non-porous cylinder wall, a certain amount of water is held inside the washing machine inner drum 1 to clean clothes. When draining water, the drain valve 6 at the bottom end of the washing machine inner drum 1 is connected to the drain pipe to drain the waste water. When the washing machine inner drum 1 holds water to wash clothes, in order to prevent the water in the washing machine inner drum 1 from seeping through the gap between the bottom end of the washing machine inner drum 1 and the rotating flange 4 and flowing to the speed reducer 5, damaging the washing machine parts, a water holding support 2 and a sealing structure 3 are provided to prevent the water in the washing machine inner drum 1 from seeping. When the rotating flange 4 rotates, the sealing structure 3 seals the gap between the rotating flange 4 and the water holding support 2. The ear-shaped sealing oil groove 303 contains a certain amount of oil, which ensures the stable rotation of the rotating flange 4. The tightening spring 304 makes the ear-shaped sealing oil groove 303 better fit the rotating flange 4. If a small amount of liquid droplets seep out of the gap between the bottom end of the washing machine inner drum 1 and the rotating flange 4 and flow to the sealing structure 3, the water-absorbing and expanding rubber 10 in the porous cylinder 11 absorbs water and expands, pushing the extrusion block 15 to move. The extrusion block 15 extrudes the oil storage box body 12 on both sides, causing the oil in the oil storage box body 12 to flow out to the transmission pipe 13 and then to the oil outlet nozzle 14. The oil droplets enter the oil infiltration groove 305 and slowly seep into the ear-shaped sealing oil groove 303 through the gap between the ear-shaped sealing oil groove 303 and the rotating flange 4 at the bottom end of the oil infiltration groove 305, strengthening the lubricating effect between the ear-shaped sealing oil groove 303 and the rotating flange 4. At the same time, the water-absorbing resin 9 absorbs water and expands, extruding the ear-shaped sealing oil groove 303 outside through the extrusion push plate 8, so that the ear-shaped sealing oil groove 303 better fits the rotating flange 4, avoiding water seepage.
