Embodiment 1

[0024] figure 1 It is a schematic structural diagram of the detergent dispensing device for washing machine provided in this embodiment, and the user can realize semi-automatic dispensing of detergent through the detergent dispensing device described in this embodiment.

[0025] The detergent dispensing device described in this embodiment includes a liquid storage chamber 1 provided with a discharge port 11, a constant volume chamber 2 provided with a water inlet 21 and communicated with the inner barrel of the washing machine, and connected to the liquid storage chamber 1 and the constant volume chamber through a one-way valve. The working chamber 3 connected to the chamber 2, and the power assembly 4 that repeatedly changes the pressure in the working chamber 3; by changing the pressure in the working chamber 3, the detergent in the liquid storage chamber 1 is sent into the constant volume chamber 2 through the working chamber 3 And enter the inner drum of the washing machin...

Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is that the switch 42 is connected to the controller, and the addition of detergent is integrated into the laundry program as a program, that is, the laundry program includes adding detergent, washing, rinsing and dehydration, and can be adjusted according to the clothes. Choose the amount of detergent to be added according to the amount of detergent and the degree of dirt. There is no need to manually turn on and off the switch 42, and the amount of detergent added is accurately controlled by the controller, so as to realize fully automatic injection of detergent. Other structures described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0035] This embodiment also provides a washing machine, including the above-mentioned detergent dispensing device for a washing machine. The washing machine realizes automatic injection of detergent through the above-mentioned detergent ...

Abstract

The invention discloses a washing-machine detergent putting device and a washing machine. The washing-machine detergent putting device comprises a liquid storage cavity, a constant-volume cavity communicated with a washing-machine inner cylinder, a working cavity communicated with the liquid storage cavity and the constant-volume cavity through a one-way valve and a power assembly enabling pressure in the working cavity to be repeatedly changed; by changing the pressured in the working cavity, detergent in the liquid storage cavity is sent to the constant-volume cavity through the working cavity and enter the washing-machine inner cylinder along with water flow. According to the washing-machine detergent putting device and the washing machine, as the liquid storage cavity, the working cavity and the constant-volume cavity which are sequentially communicated in a one-way mode are formed, the power assembly enabling the pressure in the working cavity to be changed is arranged, and the pressure in the working cavity is changed to enable the detergent in the liquid storage cavity to be sent to the constant-volume cavity through the working cavity and enter the washing-machine inner cylinder along with the water flow, semi-automatic or full-automatic putting of the detergent is achieved.

Description

technical field [0001] The invention relates to the technical field related to washing machines, in particular to a washing machine detergent injection device and a washing machine. Background technique [0002] Along with the development of washing machine detergent automatic adding technology, there is following shortcoming in the delivery device of existing washing machine: [0003] 1. The existing washing machine feeding device is mainly controlled by an electronic valve, uses the Venturi effect to realize the feeding of detergent, or installs a small pump to realize the feeding of detergent. The delivery device with the above-mentioned structure has a complex structure, resulting in high production cost of the whole machine; poor reliability, prone to failure, increased maintenance costs; and takes up a large installation space. [0004] 2. It is impossible to visually see the amount of detergent added and the remaining amount of detergent in the liquid storage box for...
