When the pumping element 2, for example, the piston pump stops being pressed in, the elastic piece 42 returns to the closed state under the action of its own elastic force, thereby achieving a leakproof effect. Among them, the detergent leakage preventing chamber 5 can hold a lotion which is used in a laundry washing process such as a detergent or a softener.

The flow direction control member 4 is made of an elastic material (such as rubber, silica gel, etc.), and the flow direction control member 4 is provided with a spring piece 42. The root portion of the spring piece 42 is fixedly connected with the flow direction control member 4, and the other edges are closely aligned with the flow direction control member 4. And can slide relative to each other. When the pressure transmitted from the liquid in the detergent leak prevention chamber 5 is sufficiently large, the elastic piece 42 can be forced to be elastically deformed, the elastic piece 42 is lifted up, and the detergent or softener flows into the flushing chamber 12.

The upper edge of the detergent leakage prevention chamber 5 is tightly fitted with the detergent leakage prevention chamber 5, and the upper edge of the detergent leakage prevention chamber 5 is higher than the washing conduit, so that the liquid level in the detergent leakage prevention chamber 5 is higher than the washing conduit The liquid level inside is effective to prevent liquid in the washing duct from leaking into the flushing chamber 12.

The detergent dispensing device 100 of the washing machine according to the embodiment of the present invention mainly includes a water distributor (also referred to as a shower) 3, a water distributor 3 cold water inlet pipe 312, a water distributor 3 hot water inlet pipe 311, a flushing chamber 12, and the like.

The water distributor 3 is embedded directly above the flushing chamber 12, and the water distributor 3 is connected to the cold water inlet pipe 312 and the hot water inlet pipe 311 to take in the water in the inlet valve. The entire water distributor 3 structure is an annular hollow cavity that closely fits along the inner wall of the flushing chamber 12. The lower part of the water distributor 3 is provided with a series of spray holes 321 which can spray and wash the washing chamber 12. The inner side of the water distributor 3 is provided with an overflow groove 322 through which the excessive water pressure can be effectively unloaded.

The hollow area of the water distributor 3 may be provided with a manual addition port 14, and the detergent, softener, washing powder and the like may be manually dispensed by manually adding the port 14. The flip cover 212 is opened from the top of the washing machine and directly placed, so that a drawer structure can be saved, the production cost is greatly reduced, and the structure is simplified.

An automatic addition port 13 for detergent and softener is disposed in the flushing chamber 12, and the flow direction control member 4 cooperates with the detergent leakage preventing chamber 5 to connect the flushing chamber 12 with the detergent storage chamber 11. Thus, the detergent storage chamber 11 can be placed inside the water inlet box, and the storage space can be increased.

The water distributor 3 is embedded in the interior of the flushing chamber 12, and can be easily disassembled by the user, and can be easily cleaned when there is detergent or the like remaining in the flushing chamber 12.

The detergent dispensing device 100 of the washing machine according to the embodiment of the present invention can deliver detergent, softener, washing powder, etc. from the top into the water inlet system, and is fully dissolved in the flushing chamber 12 and then flows into the washing tub 211. washing. The drawer structure of the conventional drum washing machine is reduced, the cost is greatly reduced, and the structure is simplified. The front door of the washing machine is a complete appearance, neat and beautiful.

The detergent dispensing device 100 of the washing machine according to the embodiment of the present invention uses a pumping member 2 such as a piston pump to respectively A detergent or softener or the like is pumped into the washing tub 211.

Specifically, the user places the laundry into the washing tub 211, and the driving motor 215 drives the laundry in the washing tub 211 to rotate. The computer board control system 213 calculates the weight of the laundry by the motor load measurement. The computer board control system 213 calculates the appropriate amount of detergent based on the weight of the laundry, and then converts it into the number of delivery cycles of the piston pump. The delivery amount of one delivery cycle of the piston pump is the delivery accuracy of the detergent.

The working principle of the pumping element 2, such as a piston pump, is divided into two steps: the first step is pumping, and the detergent is pumped from the detergent storage chamber 11 to the pump body position of the piston pump; the second step is to send, The detergent in the pump body of the piston pump is sent to the detergent leak prevention chamber 5. The increase in the detergent pressure in the detergent leak prevention chamber 5 causes the elastic piece 42 flowing to the control member 4 to be opened, and the detergent is discharged into the flushing chamber 12.

The water distributor 3 injects water to spray the flushing chamber 12, dissolves the detergent in the washing chamber 12, and rinses it into the washing tub 211 for washing.

The last time the influent water is rinsed, the pumping element 2, such as a piston pump, draws the detergent or softener from the detergent storage chamber 11 into the detergent leak prevention chamber 5 based on the information calculated by the computer board control system 213. The increase in the detergent pressure in the detergent leak prevention chamber 5 causes the elastic piece 42 flowing to the control member 4 to be pushed up, and the detergent or softener is discharged into the flushing chamber 12. The water dispenser 3 dissolves and rinses the detergent of the washing chamber 12 into the washing tub 211 for washing or softening treatment.

The manual adding port 14 can directly directly put detergent powder, softener, detergent and the like into the washing chamber 12, and the water distributor 3 re-injects water to spray the washing chamber 12 to dissolve the washing powder, softener, detergent and flush to the washing tub 211. in.

The detergent dispensing device 100 of the washing machine according to the embodiment of the invention can conveniently and accurately control the dosage of detergents and softeners, and can store detergents and softeners of sufficient capacity to reduce the user's addition of filling detergents and softeners. The number of times is also accompanied by a manual addition port 14 for manually adding detergent, detergent, softener, and the like.
