[0023] Embodiment 2:

[0024] In the prior art, the fixed connection between the clutch upper sleeve and the washing tub 1 is either directly integrated, or the clutch upper sleeve is directly fixed to the bottom of the washing tub 1. However, more often, a flange 2 is provided at the bottom of the washing tub 1 to consider the fixing strength, and the clutch upper sleeve and the flange 2 are fixed. The fixing part of the clutch upper sleeve and the flange 2 is usually adopted in that: the position where the clutch upper sleeve and the flange are fixed is usually located on the horizontal plane at the bottom of the washing tub 1. In this case, no matter what, it is impossible to find a place for the water flow passage of the washing tub 1, unless, as described in the background art, the water hole is restricted by the diameter of the clutch upper sleeve and the flange or the connecting piece, resulting in poor water flow. In the prior art, although there is also a concave portion formed at the bottom of the washing tub, these practices are designed for other purposes. One of the most important structural designs of the present invention is to fix the upper sleeve of the clutch and the washing tub 1 to a position higher than the lower plane of the bottom of the washing tub or lower than the lower plane of the washing tub, so that the side formed by the height difference has sufficient drainage and water flow space, and / or the diameter of the fixed connection between the upper sleeve of the clutch and the water inlet structure B is smaller than the diameter of the inner wall of the water inlet structure B.

[0025] Specifically, Figure 1-10 As shown, the present invention discloses a washing machine structure, including an outer tub 10, a washing tub 1, a flange and a deceleration clutch 11, the washing tub 1 is fixedly connected to the clutch upper sleeve, the impeller is fixedly connected to the impeller shaft, and a water-passing device A is arranged on the upper part of the deceleration clutch 11. Refers to a water flow device arranged below the washing tub 1. No drainage hole is arranged at the lower part of the washing tub 1. The washing water in the washing tub 1 flows to the water flow device A and then flows to the drainage structure of the washing machine. The water flow device A is connected to the washing tub 1 through the water inlet structure B. A water flow ring 4 is arranged below the flange 2. A downward sealing ring 6 is formed on the lower surface in the middle of the water flow ring 4. The fixed position of the washing tub 1 and the upper shaft sleeve of the clutch is higher than the upper plane of the bottom of the washing tub 1. The water inlet structure forms a side discharge hole 7 above the bottom of the washing tub 1. The side discharge hole 7 here is for flowing the washing water in the washing tub 1 to the water flow device A. A water flow channel 4 is formed between the inner wall of the sealing ring 6 and the upper shaft sleeve of the clutch. The water flow channel 4 is connected to the water flow channel 9 of the water flow device A. An internal drain port 12 is arranged on the water flow device A, and the internal drain port 12 is connected to the drainage structure of the washing machine.

[0026] Example 3

This arrangement greatly increases the water inlet area of ​​the water inlet structure B of the water flow device A by providing the inclined side holes 7 on the water flow bowl 3. On the premise of meeting the connection strength between the water flow device A and the flange 2, the washing tub 1, and the upper sleeve of the clutch, the circulation efficiency of the washing water is improved, and it is avoided that hair or washing materials clog the water inlet structure of the water flow device during use, thereby affecting the normal use of the washing machine; and under this scheme, the contact surface between the sealing ring 6 and the water flow device A is small, so that sealing can be achieved through a smaller upper water seal 8, thereby reducing the possibility of overflow of the washing water.

[0028] Preferably, the side discharge holes 7 described herein may be arranged in a right angle, an arc shape, or an oblique line shape, and the washing water may enter from the side of the water bowl 3 or from the top surface and the side of the water bowl 3 .

[0029] Preferably, the water bowl 3 and the flange 2, and the water bowl 3 and the water ring 4 are all connected by bolts. The bolt holes connecting the water bowl 3 and the flange, and the bolt holes connecting the water bowl 3 and the water ring 4 can be shared or used differently. The different use here means that the water bowl 3 is fixedly connected to the water ring 4 and the flange using different bolt holes, respectively.

[0030] Embodiment 4:

[0031] like Fig. 9 As shown, as an embodiment of the present invention, a flange structure is disclosed, wherein the flange 2 is fixedly connected to the bottom of the washing tub 1, and the flange 2 forms a flange groove near the upper sleeve of the clutch, and the flange 2 includes a flange horizontal portion 201 and a flange recessed portion 202, and the flange groove is upwardly arranged in a direction away from the outer tub 10, and a flange first connection portion 203 is formed at the top of the flange groove, and the flange first connection portion 203 is configured to be fixedly connected to the upper sleeve of the clutch, and the washing shaft passes through the flange first connection portion 203, and the flange 2 forms a flange second connection portion 204 near the flange groove, and the flange second connection portion 204 is formed on the flange horizontal portion 201, and the flange second The connection part 204 is configured to be fixedly connected with the water ring 4. The height of the first flange connection part 203 is higher than that of the second flange connection part 204. The first flange connection part 203 and the second flange connection part 204 form a height difference. A flange lateral drainage hole 205 is provided between the first flange connection part 203 and the second flange connection part 204. A downward sealing ring 6 is formed on the lower surface in the middle of the water ring 4. A water passage 5 is formed between the sealing ring 6 and the upper sleeve of the clutch. The washing water in the washing bucket 1 flows to the water passage 5 through the flange lateral drainage hole 205, and then flows to the water device A. The sealing ring 6 and the upper water seal 8 of the water device A are slidably sealed, and an inner lip is provided at the contact connection between the sealing ring 6 and the upper water seal 8. This setting changes the flange structure, and the flange lateral drainage hole provided greatly increases the water inlet of the water device under the premise of ensuring the flange connection strength.

[0032] Preferably, the flange lateral drainage hole 205 here can be set in a right angle, arc shape, or oblique line shape, and the washing water can enter from the side of the flange 2 or from the top surface and side of the flange 2.

[0033] It should be pointed out that, for those skilled in the art, several improvements and modifications may be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
