【detailed description】

The technical solutions of the embodiments of the present invention will be explained and described below in conjunction with the accompanying drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present invention.

Referring to Fig. 1, the detergent dissolving and foaming mechanism of a washing machine according to a preferred embodiment of the present invention includes a detergent box assembly 2 and a water inlet channel 3 arranged on a dehydration tub frame assembly 1. Referring to Fig. 3, the dehydration tub frame assembly 1 includes a dehydration tub assembly 1 Bucket frame 11, window sealing ring 12 and water inlet joint 13, dehydration bucket frame 11 is provided with water inlet 110, forms water outlet 10 in the inner side of window sealing ring 12, window sealing ring 12, water inlet joint 13 and dehydration bucket frame The space surrounded by 11 is the water inlet channel of this embodiment, and the water outlet 10 is located at the lower side of the lip of the drum 4 , and the water and/or detergent flowing out from the water outlet 10 can directly enter the drum 4 .

1 and 2, the water inlet 110 is connected to the detergent box 21 of the detergent box assembly 2 through the water inlet pipe 6, and the detergent solution in the detergent box 21 enters the water inlet channel 3 through the water inlet pipe 6. In this embodiment, The water inlet channel 3 is also connected with a spraying device. Referring to FIG. 4 , the spraying device of this embodiment includes a spraying pipe 5 . One end of the spray pipe 5 is connected to the spray port 31 provided on the side wall of the water inlet passage 3, and the other end of the spray pipe 5 is connected to the water inlet valve 22 of the detergent box assembly 2, and the water inlet valve 22 works to pass through the water inlet valve. The shower pipe 5 injects impact water flow into the water inlet channel 3, and the side wall of the water inlet channel 3 opposite to the impact direction of the impact water flow is provided with a baffle plate 32, as shown in Figure 4, the spray port 31 is located On the upper side wall, a baffle plate 32 is arranged on the lower side wall of the water inlet channel 3. When the detergent solution enters the water inlet channel 3, it is impacted by the water flow, and the baffle plate 32 prevents the detergent solution from directly flowing out of the water outlet 10, and The rotating water flow is generated in the water inlet channel 3, and the detergent solution is in contact with the air in the water inlet channel 3 for secondary dissolution and foaming (the primary dissolution and foaming is performed in the detergent box), so that the detergent is fully absorbed in the water inlet channel 3. Dissolving and foaming to produce rich foam, rich and delicate foam is easier to penetrate into the clothes, improving the washing rate of clothes. In addition, the foaming of the detergent solution by the impact of the water flow requires air to be in contact with it, so the detergent solution in this embodiment does not fill the entire water inlet channel, but leaves an upper space so that the air can enter and participate in the foaming of the detergent. Bubble.

During actual use, due to the existence of the baffle, when the washing machine stops water intake, the water at the bottom is blocked by the baffle and cannot flow out from the water outlet. In order to drain the remaining water, a small hole can be made on the side wall of the channel near the baffle. In the washing process, although the small hole also discharges water, the rotating water flow formed in the water inlet channel makes the water discharge at the small hole not very large, and only a small amount of water flows into the drum from the small hole, so the setting of the small hole is very important. The impact of detergent dissolving and foaming in the water inlet channel is minimal, and it is not enough to affect the water flow at the water outlet.

As shown in Figures 3 and 4, the baffle 32 of this embodiment is close to the water outlet 10, and the baffle 32 is inclined toward the water outlet 10 of the water inlet channel 3, and the impact point 51 of the impacting water flow is located between the baffle 32 and the water outlet 10. The intersection of the side walls of the water inlet channel 3 or the intersection of the baffle plate 32 and the side wall of the water inlet channel 3, that is, the impact point 51 of the water flow is close to the water outlet 10 of the water inlet channel 3, so as to avoid detergent solution and foam remaining in the water inlet channel Inside, because the impact point of the water flow is close to the water outlet of the water inlet channel, the foam formed by the impact can directly enter the drum from the water outlet.

With reference to Fig. 4, in order to improve the impact effect of the water flow of the spray device, the caliber design of the spray port 31 is relatively small, and the water flow of the spray pipe 5 has a higher flow rate when passing through the spray port 31, so as to effectively impact the detergent solution, so as to improve Foaming effect of detergent. As shown in Figure 4, a spray joint 52 is arranged on the upper side wall of the water inlet channel 3, and the spray pipe 5 is sleeved on the spray joint. The diameter of the spout 31 is preferably designed to be 1.5mm-3mm.

Those skilled in the art can imagine that this embodiment realizes the impact flow of the detergent solution in the water inlet channel. In addition to water flow, it can also be air flow, water-air mixed flow, etc. Therefore, the spray pipe can also be connected to the water pump. Or on the air pump. Certainly, in this embodiment, the spray pipe is connected to the water inlet valve of the detergent box assembly, and the water inlet valve can be used to provide impact water flow, without additional water pump or air pump, the structure is simple, and the implementation cost is reduced.

Referring to Fig. 2, the detergent box assembly of the present embodiment includes a detergent box 21 and a water inlet valve 22, and the detergent box 21 is provided with a main wash detergent storage area 211, a softener storage area 212 and a prewash detergent storage area 213, the water inlet valve 22 adopts a double water inlet valve, that is, the water inlet valve 22 is provided with a first nozzle 221 and a second nozzle 222, the first nozzle 221 communicates with the main wash detergent storage area 211 through the first connecting pipe 23, and the second The second nozzle 222 communicates with the pre-washing detergent storage area 213 through the second connecting pipe 24, the first connecting pipe communicates with the second connecting pipe and the cross connection 25 communicates with the softener storage area 212, and the above-mentioned spray pipe 5 is connected to the second connecting pipe. Take over 24 on.

The pre-washing function of the washing machine is before the main washing function, and the main washing function and the foaming function can be performed at the same time, or the main washing function can be performed separately, and the softener function is performed last. The detergent powder corresponding to the main wash function and the pre-wash function and the softener corresponding to the softener function have been added in the early stage.

The first nozzle 221 is opened separately, and there is water in the main wash detergent storage area 211; the second nozzle 222 is opened separately, and there is water in the prewash detergent storage area 213 and the spray pipe; the first nozzle 221 and the second nozzle 222 open simultaneously, main wash detergent storage area 211, softener storage area 212 and pre-wash detergent storage area 213 and spray pipe all have water.

The dissolving and foaming function is usually carried out simultaneously with the main washing function, which requires water in the spray pipe, but at this time the pre-washing function has ended and the softener function has not yet started, so the first nozzle 221 and the second nozzle 222 cannot be opened at the same time , the present embodiment adopts the following control steps:

1. The first nozzle 221 is turned on for T1 time to flush part of the detergent in the main washing detergent storage area 211 into the water inlet channel;

2. The first nozzle 221 is closed, and the second nozzle 222 is opened for T2 time to perform impact dissolution and foaming;

3. The first nozzle 221 and the second nozzle 222 are turned on alternately for each T3 time, and after N cycles, the first nozzle 221 is normally turned on until the water inflow ends.

Since the opening and closing of the water inlet valve 22 generally takes 1 second, in order to ensure that the first nozzle 221 and the second nozzle 222 do not open at the same time, in the process of alternately opening the first nozzle 221 and the second nozzle 222, there is One second is a state in which both the first nozzle 221 and the second nozzle 222 are closed.

Since the spray pipe 5 is connected to the second connecting pipe 24, when the second nozzle 222 is opened, part of the water enters the water inlet channel through the spray pipe 5 to impact and foam the detergent solution. Dissolving and foaming of the detergent can be realized. Compared with the existing triple water inlet valve, this embodiment reduces the cost of accessories.

Applying the above-mentioned embodiment to the drum washing machine usually adopts the water-forward mode. When the water-forward drum washing machine enters the water, the drum rotates continuously, and the water/detergent foam is sprayed on the clothes and fully contacts with the clothes, increasing the Decontamination effect, improve cleaning ability. At the same time, users can intuitively see the water inlet effect through the transparent glass door.
