Embodiment 1

[0043] 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 with the constant volume chamber. The cavity 4 is communicated, and a one-way valve and / or a float valve are set in the two negative pressure tubes and the suction tube 6, and the injected liquid flows to the constant volume cavity 4 or constant volume by changing the water inlet status of the two Venturi tubes The delivery liquid in the chamber 4 is delivered to the de...

Embodiment 2

[0063] Example 2, such as Figure 1-11 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.

[0064] 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 .

[0065] This arrangement facilitates that the drawer box assembly can be quickly and conveniently pulled apart or pushed in as required during use.

[0066] Preferably, a casing 24 is provided outside the drawer box base 29 , and the casing 24 wraps around the drawer box base 29 and...

Embodiment 3

[0069] Embodiment 3, the present invention also discloses a washing machine, comprising the detergent injection device as described in Embodiment 1 or Embodiment 2.

[0070] The washing machine can drop the liquid in the first chamber 14 multiple times as needed through the control program.

[0071] Preferably, the detergent dispensing device can be an independent external dispensing device, or can be a dispensing device integrated on the washing machine, and the dispensing device forms a highly integrated dispensing device with the main water inlet valve and the water inlet box on the washing machine. device.

[0072] Preferably, the detergent dispensing device shares the main water inlet solenoid valve of the washing machine, that is, the water inlet valve 22, and the solenoid valve can have a corresponding number of control switching ports according to the type of liquid to be dispensed, for controlling the dispensing of different toiletries.

Abstract

The invention provides a detergent feeding device and a washing machine. The detergent feeding device includes a feeding containing cavity, wherein a first cavity is arranged in the feeding containing cavity, feeding liquid is stored in the first cavity, the first cavity is in communication with a constant volume cavity through a liquid suction tube, 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 are in communication with the constant volume cavity, one-way valves and / or floating ball valves are arranged in the two negative pressure tubes and the liquid suction tube. By changing water feeding states of the two Venturi tubes, the feeding liquid flows towards the constant volume cavity or the feeding liquid in the constant volume cavity is fed into the feeding containing cavity. By arranging the two Venturi tube structures, a double-Venturi negative-pressure single-throwing automatic feeding assembly is formed, suction and feeding of the feeding liquid are completed in a double-negative-pressure mode, the structure is reasonable, control is accurate, the structure for controlling automatic feeding of 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...
