Embodiment 1

[0075] like Figure 1-11 As shown, the invention discloses a detergent delivery device, comprising:

[0076] A detergent box body 8, the detergent box body 8 includes at least one first cavity 9, and the first cavity 9 is used to accommodate and store a liquid dosing solvent;

[0077] A uniform water box support 7, a water uniform mixing chamber 15 is arranged on the water uniform box holder 7, and a discharge port 16 is arranged at the lowest point of the water uniform mixing chamber 15;

[0078] A dosing device, the dosing device is used to absorb and put the liquid dosing solvent in the first cavity 9 into the homogeneous water mixing chamber 15;

[0079] When the dispensing device is working, the liquid detergent in the first chamber 9 is sucked into the dispensing device through the liquid detergent inlet 64 on the first chamber 9, and can be discharged into the uniform water mixing chamber as the dispensing device works. 15. The liquid feeding solvent and water are mix...

Embodiment 2

[0106] Example 2, such as Figure 1-13 As shown, the present invention discloses another detergent dispensing device. A one-way valve is set between the liquid detergent inlet 64 and the Venturi tube negative pressure suction inlet 63, and the one-way valve makes the first The liquid dosing solvent in the first cavity 9 can only flow to the Venturi tube negative pressure suction port 63 through the liquid detergent inlet 64 , and prevent the water flow in the Venturi tube structure 6 from flowing to the first cavity 9 . Other structures are with embodiment 1.

[0107] This arrangement prevents the water from flowing backward into the first chamber 9 when the water pressure of the water inlet device is too high.

[0108] Preferably, the one-way valve includes a plug 67, a valve plug 65 and a second adjustment spring 66, the plug 67 is arranged at the liquid detergent inlet 64, the plug 67 has a conical surface or a step On the other hand, one end of the second adjustment spri...

Embodiment 3

[0111] Example 3, such as Figure 1-14 As shown, the present invention discloses another detergent dispensing device. A pressure relief valve device 4a is arranged at the front end of the Venturi pipe structure 6, and the pressure relief valve device 4a is used to discharge the water at the Venturi pipe inlet 61. Drainage and pressure relief are performed when the pressure is too large, and other structures are the same as other embodiments.

[0112] When the water pressure passing through the Venturi tube exceeds the set water pressure, the pressure relief valve opens, and water flows into the second chamber 13 from the pressure relief valve, thereby reducing the water pressure in the Venturi tube and enabling it to be used effectively.

[0113] The pressure relief valve device 4a includes a pressure relief valve cover 40, a pressure relief port 41, a rubber valve plug 42 and a first adjustment spring 43, and the rubber valve plug 42 and the first adjustment spring 43 are use...

Abstract

The invention provides a detergent putting device and a washing machine. The detergent putting device comprises a detergent box body and a water uniformizing box support; the detergent box body comprises a second box body, the second box body is internally provided with at least one first accommodating cavity, and the first accommodating cavity is used for accommodating and storing a liquid putting solvent; a water uniformizing mixing cavity is formed in the water uniformizing box support; the liquid putting solvent in the first accommodating cavity flows to the water uniformizing mixing cavity under the action of a water inlet device and a putting pipeline; and the putting method comprises the following steps that the putting amount of the detergent is controlled through an electric control board, after information of the water inlet amount, the water inlet speed, the temperature and the viscosity of the detergent is collected, a putting amount signal is given through empirical data, then the on-off time of a putting control valve is controlled, and the putting amount of the detergent is adjusted and controlled through temperature and water pressure compensation. The detergent putting device and the washing machine are ingenious in structure, accurate in control and reliable in use.

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...
