Problems solved by technology

This automatic detergent delivery method has certain requirements for the design and assembly of the structure, and the structure is relatively complicated and the cost is high to realize.
In addition, some washing machines are fed by motor-driven gear pumps, peristaltic pumps, and piston pumps. This method requires additional motors and pumps, which is costly and cannot achieve accurate quantitative feeding.
[0004] In view of this, the present invention mainly solves the problems of inaccurate automatic adding of detergents in existing washing machines and poor variety of dosing performance, and provides a method for controlling the dosing of laundry treatment agents that can accurately and quantitatively add a variety of detergents and care agents with different functions

Embodiment 1

[0039] The washing machine of this embodiment includes a storage device for storing the laundry treatment agent and a delivery device for putting the laundry treatment agent. The delivery device has a hollow chamber, and a separator is sealed and installed in the hollow chamber to separate the hollow chamber. The chamber is divided into a water inlet chamber and a liquid storage chamber. The water inlet chamber has a water inlet end and a pressure relief end. The water inlet end is connected to the water inlet control device of the washing machine. The liquid storage chamber has a liquid inlet end and a liquid outlet end. storage device.

[0040] When the water inlet control device is turned on, the laundry water enters the water inlet chamber of the dispensing device from the water inlet end, and flows out from the pressure relief end. The laundry water drives the separator to move toward the liquid storage chamber or squeezes the separator to deform into the liquid storage ch...

Embodiment 2

[0071] Such as Figure 1-Figure 3 As shown, the washing machine of this embodiment includes an integrated storage device and a delivery device; the storage device has a storage chamber 203, and the laundry treatment agent is stored in the storage chamber 203; The device has a hollow chamber, and a flexible separator 110 is installed in the hollow chamber to separate the hollow chamber into a water inlet chamber and a liquid storage chamber; the liquid storage chamber has a liquid inlet end 115 and a liquid outlet end, and the liquid inlet end 115 It communicates with the storage chamber 203; the water of the washing machine flows into / out of the water inlet chamber, presses the flexible separator to deform to the liquid storage chamber, and discharges the laundry treatment agent contained in the liquid storage chamber from the liquid outlet.

[0072] In this implementation, the storage of the laundry treatment agent is realized through the storage device, and the automatic del...

Embodiment 3

[0090] Such as Figure 1-Figure 3 As shown, the dispensing device of this embodiment includes a housing, which has at least two hollow chambers inside, and a flexible partition 110 is sealed and installed in each hollow chamber to separate each hollow chamber into a water inlet chamber and a water inlet chamber. A liquid storage chamber; the housing is respectively provided with a water inlet end and a pressure relief end connected to the water inlet chamber corresponding to each hollow chamber, and the water inlet end is connected with the water inlet pipeline of the washing machine; the housing is corresponding to each hollow chamber The chambers are respectively provided with liquid outlets connected to the liquid storage chamber, and the laundry treatment agent is placed in the liquid storage chamber; the water inlet of the washing machine enters the water inlet chamber from the water inlet end, and the flexible separator 110 is squeezed to deform into the liquid storage ch...

Abstract

The invention provides a clothes processing agent feeding control method of a washing machine. The washing machine comprises a storage device for storing clothes processing agent and a feeding devicefor feeding the clothes processing agent, wherein the feeding device comprises a hollow cavity inside which a separating unit is mounted in a sealed mode to separate the hollow cavity into a water inlet cavity and a liquid storage cavity, the water inlet cavity is provided with a water inlet end and a pressure relief end, the water inlet end is communicated with a water inlet control device of thewashing machine, the liquid storage cavity is provided with a liquid inlet end and a liquid outlet end, and the liquid inlet end is communicated with the storage device. The clothes processing agentfeeding control method comprises that the washing machine determines the number of times of feeding N of the feeding device according to the total amount to be fed M of the clothes processing agent, the single fixed feeding amount m of the feeding device and the water inlet velocity V of the washing machine and controls the numbers of opening and closing of the water inlet control device accordingto the number of times of feeding. According to the feeding principles of the feeding device, the clothes processing agent feeding control method of the washing machine takes into full considerationthe influence of the water inlet velocity on the single fixed feeding amount and improves the feeding precision of the clothes processing agent.

Description

technical field [0001] The invention relates to the technical field of automatic injection of laundry treatment agents in washing machines, in particular to a method for controlling injection of laundry treatment agents in washing machines. Background technique [0002] Washing machine, as the most common household appliance used in people's daily life, with the continuous development and progress of technology, the research and development of washing machine pays more and more attention to improving the user experience on the basis of meeting people's basic laundry requirements. More and more washing machines have the function of automatically adding detergent, so that users no longer need to manually add detergent when using the washing machine, which greatly facilitates the use of users and improves the user experience. [0003] The automatic adding method of detergent in existing washing machines generally adopts the Venturi principle. The change in the diameter of the w...
