Detailed ways

A general washing machine has a control system, a water inlet assembly, a dehydration bucket 2 and a water tank 1, as shown in Fig. 1, the water inlet assembly includes a water inlet pipe 3 that feeds water into the range of the dehydration bucket 2, and the top of the water bucket 1 is provided with a fixed frame 5 , There is an annular gap S between the outside of the dehydration tub 2 and the inside of the tub 1 . In order to simultaneously eliminate the foam in the area of the dehydration bucket 2 and in the annular gap S, the following embodiment is used.

Embodiment one:

The present embodiment provides the defoaming structure of the washing machine, as shown in Figures 2 and 3, comprising a water inlet pipe 3, a water inlet branch pipe 31 and a water diversion component 4, the water inlet end of the water inlet branch pipe 31 is connected with the water inlet pipe 3, and the water outlet end is fixed on a fixed On the frame 5, the water diversion part 4 is fixed on the fixed frame 5 by means of screw connection and the like, and a part is located below the outlet end of the water inlet branch pipe 31. A plurality of water outlet holes 41 are arranged in the circumferential direction of the annular gap S. The water inlet branch pipe 31 can also directly feed water alone, but the extra pipeline is relatively long, and in this embodiment, the water inlet branch pipe 31 is connected to the water inlet pipe 3, and the pipeline is relatively short, which saves cost. A water inlet hole 51 connected to the water inlet pipe 3 and a defoaming hole 52 connected to the water inlet branch pipe 31 are correspondingly provided on the fixed frame 5 , see FIG. 4 and FIG. 5 .

In this embodiment, in order to achieve water defoaming into the entire annular gap S, the water guide member 4 is an annular groove body, which corresponds to the annular gap S and is located at the top of the annular gap S. The portion below the water outlet of the water inlet branch pipe 31 on the annular tank body is the water inlet proximal end 401, and the part of the annular tank body away from the water inlet branch pipe 31 water outlet end is the water inlet distal end 402, as shown in Figure 6, the water outlet hole 41 is set On the side wall of the annular tank body, the bottom surface of the water inlet distal end 402 is also provided with water outlet holes 41, the water outlet holes 41 are distributed on the same plane, the annular tank body is installed horizontally, and the plane where the water outlet holes 41 are distributed is inclined relative to the horizontal plane. And the water outlet hole located at the near end of the water inlet is higher than the water outlet hole 41 at the far end of the water inlet, and the plane of the water outlet hole distribution is inclined at an angle of 3° to 8° relative to the horizontal plane, such as 3°, 4°, 5°, 6°, 7° or 8°, etc., if the inclined distribution angle of the water outlet is too large, the water will flow directly to the far end 402 of the water inlet along the annular groove, and the water may not flow from the water outlet near the near end 401 of the water inlet. 41, causing the defoaming range to be limited to the bottom near the water inlet distal end 402 of the annular tank body, the defoaming effect is not good, and the angle of inclination distribution of the water outlet holes is too small, so that the inlet water cannot flow quickly along the annular tank body to the water inlet far end 402, but on the way it has already flowed out from the water outlet hole 41 near the water inlet near end 401, resulting in the defoaming range being limited to the bottom near the water inlet near end 401 of the annular tank body, and effective defoaming cannot be achieved as well. .

In addition, the annular tank body can also be installed obliquely, specifically, it is inclined downward relative to the fixed frame 5 from the near water inlet 401 to the distal end 402 of the water inlet, and the angle of inclination of the annular tank relative to the fixed frame 5 is 3° to 8°, for example 3°, 4°, 5°, 6°, 7° or 8°, etc. Similarly, if the installation angle of the annular tank is too large, the water will flow directly along the annular tank to the far end of the water inlet 402 , the water may not flow out from the water outlet hole 41 near the water inlet proximal end 401, resulting in the defoaming range being limited to the bottom near the water inlet distal end 402 of the annular tank body, the defoaming effect is not good, and the annular tank body is installed obliquely If the angle is too small, the inlet water cannot quickly flow along the annular groove to the water inlet distal end 402, but on the way it has already flowed out from the water outlet hole 41 near the water inlet proximal end 401, resulting in the defoaming range being limited to the annular groove The bottom near the water inlet proximal end 401 of the body also cannot achieve effective defoaming.

And in order to allow water to flow from the water inlet proximal end 401 of the annular tank body to the water inlet distal end 402, it is better that the water outlet hole 41 is arranged on the side wall of the annular tank body, and on the inner ring side wall of the annular tank body Water outlet holes 41 can be set on the side wall of the outer ring. The water outlet holes 41 are distributed along the circumference on the annular groove body, calculated by angle, the distance between two adjacent water outlet holes 41 is 3°～6°, such as 3°, 4°, 5° or 6°, two If the interval angle between the water outlet holes 41 is too large, the discharge speed of the inflow water from the water outlet holes 41 will be slow and the flow rate will be small, which will affect the defoaming effect. If the interval angle between the two water outlet holes 41 is too small, it will cause Most of the water has flowed out from the water outlet hole 41 at the water inlet proximal end 401 of the annular tank body, resulting in less water at the water inlet distal end 402 of the annular tank body, resulting in uneven defoaming, which affects the defoaming effect. The water outlet holes 41 can be evenly distributed on the annular tank body, or gradually from the water inlet proximal end 401 to the water inlet distal end 402 from sparse to dense, that is, the interval angle is getting smaller and smaller, so that all the holes on the entire annular tank body can be guaranteed. The flow rate of the water outlet hole 41 is relatively uniform, which ensures the defoaming effect of the entire annular gap S.

The specific defoaming method includes the following steps: after the washing machine drain procedure is finished, the control system controls the dehydration bucket 2 to rotate at a low speed for 10 seconds, and the control system controls the water inlet component to enter the dehydration bucket 2 to eliminate dehydration when the dehydration bucket 2 rotates. Foam in the range of bucket 2, and water into the gap between the dehydration bucket 2 and the water bucket 1 at the same time to eliminate the foam in the gap between the dehydration bucket 2 and the water bucket 1. After 10 seconds, the control system controls the water inlet component End with water. The dehydration barrel 2 rotates at a low speed and can adopt half-power operation. The low-speed rotation of the dehydration bucket 2 can pull the foam and make the large foam burst. The water inlet component feeds water into the range of the dehydration bucket 2, and then through the low-speed rotation of the dehydration bucket 2, all the places within the range of the dehydration bucket 2 are covered with water, so that the foam in the range of the dehydration bucket 2 is broken by the impact of the water inlet At the same time, the water inlet assembly enters the gap between the dehydration bucket 2 and the water tank 1, thereby eliminating the foam in the gap between the dehydration bucket 2 and the water tank 1. In order to eliminate the foam in the gap between the dehydration bucket 2 and the water tub 1 more effectively, water can be fed into the entire annular gap S between the dehydration bucket 2 and the water bucket 1 through the water inlet assembly.

The time that the control system controls the dehydration bucket 2 to rotate at a low speed can be controlled in other time ranges in 5 to 30 seconds, such as 6 seconds, 12 seconds, 15 seconds, 20 seconds, 24 seconds, 30 seconds or the like, except for 10 seconds. The weight of the clothes is small, the amount of detergent is less, and the amount of washing water is correspondingly reduced, so the amount of foam will be relatively small, so this time can be adjusted according to the weight of the clothes and the amount of washing water.

In addition to the annular groove, the water diversion part 4 of the present embodiment can also adopt an annular pipe body, which is connected with a water inlet connecting pipe connected with the water inlet branch pipe, and the pipe wall of the annular pipe body is provided with a water outlet hole 41, because the annular pipe body There will be no overflow problem that exists in the annular tank body, so the aperture of the water outlet hole 41 can be set smaller, so that the water flow ejected from the water outlet hole 41 has a certain pressure, and the foam can be better eliminated.
