Embodiment 1

[0044] Example 1, such as Figure 1~5 As shown, the present invention discloses a detergent dispensing device, comprising a dispensing chamber 13, a first chamber 14 is arranged in the dispensing chamber 13, and liquid is stored in the first chamber 14, and the dispensing liquid is stored in the dispensing chamber 13. The first chamber 14 communicates with the constant volume chamber 4 through the liquid suction pipe 6, and the constant volume chamber 4 is connected with the water inlet valve 22 through two Venturi tube structures, and the negative pressure pipes of the two Venturi tube structures are connected to the constant volume chamber. The chamber 4 is connected, and a one-way valve and / or a float valve are set in the two negative pressure pipes and the suction pipe 6. By changing the water inlet status of the two Venturi tubes, the injected liquid flows into the constant volume chamber 4 or constant volume The delivery liquid in the chamber 4 is delivered to the delive...

Embodiment 2

[0064] Example 2, such as Figure 6 As shown, the present invention discloses another detergent dispensing device, including a dispensing chamber 13, a chamber assembly is arranged in the dispensing chamber 13, and the chamber assembly and the fixed volume chamber 4 pass through the liquid suction pipe 6 The chamber assembly includes at least two chambers, and liquid can be placed in each chamber, and a reversing valve 30 is arranged on the suction pipe 6, and the reversing valve 30 is connected to the chamber through the suction pipe 6. The chambers in the chamber assembly are connected, and the constant volume chamber 4 is connected to the water inlet valve 22 through two Venturi tube structures, and the negative pressure pipes of the two Venturi tube structures are connected to the constant volume chamber 4. One-way valve and / or ball float valve are set in pipe, liquid suction pipe 6, by changing the water inlet state of two Venturi tubes, make the injection liquid flow to ...

Embodiment 3

[0079] Example 3, such as Figure 1-12 As shown, the present invention discloses a detergent dispensing device, comprising a drawer box base 29 and a drawer box cover plate 28, and a dispensing chamber 13 is formed between the drawer box base 29 and the drawer box cover plate 28. The top of the drawer box cover plate 28 is successively provided with a detergent cover plate 27 and a top cover plate 23, the constant volume chamber 4 is formed between the top cover plate 23 and the detergent cover plate 27, and other structures are the same as Example 1.

[0080] Preferably, a front panel 25 is provided on the front end of the drawer box base 29 , and a handle 26 is provided on the front panel 25 .

[0081] This arrangement facilitates that the drawer box assembly can be quickly and conveniently pulled apart or pushed in as required during use.

[0082] Preferably, a casing 24 is provided outside the drawer box base 29 , and the casing 24 wraps around the drawer box base 29 and...

Abstract

The invention provides a detergent feeding device and a washing machine. The detergent feeding device comprises a feeding cavity; a cavity assembly is arranged in the feeding cavity; the cavity assembly communicates with a constant volume cavity through a liquid suction pipe; the cavity assembly comprises at least two cavities; fed liquid can be placed in each cavity; a switching valve is arranged on the liquid suction pipe; the constant volume cavity is connected with a water inlet valve through two Venturi tube structures; negative pressure tubes of the two Venturi tube structures communicate with the constant volume cavity; and one-way valves and / or floating ball valves are arranged in the two negative pressure tubes and the liquid suction pipe. By changing the water inlet states of the two Venturi tubes, the fed liquid flows to the constant volume cavity or the fed liquid in the constant volume cavity is fed into the feeding cavity. By arranging the two Venturi tube structures, a double-Venturi negative-pressure multi-feeding automatic feeding assembly is formed, the structure is reasonable, the control is accurate, the control structure for automatic feeding of a detergent is greatly simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a detergent dispensing device and a washing machine. Background technique [0002] At present, various washing machine manufacturers have launched washing machines with automatic feeding function. This kind of washing machine can realize the intelligent addition of detergent, avoiding users from manually adding detergent, which is more convenient and has a good user experience. With the advancement of science and technology and the increasingly perfect functions of washing machines, users have higher and higher requirements for the technology of automatically injecting detergent into washing machines. The detergent dispensing devices in the related art generally use piston pumps, centrifugal pumps, peristaltic pumps and solenoid valves, etc. to directly dispense detergent into the water tank. Washing performance, and the clothes will be damaged due to the direct con...
