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 detergent addition in existing washing machines and poor performance of multiple injections, and provides a washing machine with automatic multifunctional detergent addition. Specifically, it provides a more optimized principle, which is practical The operation is more convenient and feasible, and the automatic dosing system that can accurately and quantitatively add a variety of different functional detergents and care agents

Embodiment 1

[0048] like Figure 1-Figure 5 As shown, the laundry treatment agent dispensing device of this embodiment includes a housing 100, and the housing 100 has at least two hollow chambers inside, and a flexible separator 600 is sealed and installed in each hollow chamber to separate each hollow chamber. It is a water inlet chamber and a liquid storage chamber; the housing 100 is respectively provided with a water inlet end and a pressure relief end connected with 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 100 is provided with liquid outlets connected to the liquid storage chambers corresponding to the hollow chambers, and the liquid storage chambers are filled with laundry treatment agents; the water inlet of the washing machine enters the water inlet chamber from the water inlet end, and squeezes the flexible separator. The 600 is deformed toward the liquid sto...

Embodiment 2

[0070]The dispensing device of this embodiment further provides a one-way conduction device suitable for the liquid outlet and the liquid inlet on the basis of the first embodiment, specifically:

[0071] like Figure 3-Figure 5 As shown, the one-way conducting device 1000 described in this embodiment includes a valve body 1002, a valve cover 1001, a valve core 1004 and a return spring 1003. The valve body 1002 has a hollow passage inside; the valve cover 1001 is arranged on the valve body One end of the hollow channel of 1002, a valve hole is opened on the bonnet 1001; the valve core 1004 is arranged in the hollow channel of the valve body 1002, and one end of the spool 1004 can be relatively movable and installed on the bonnet 1001, and the other end is connected with the hollow channel. The channel openings of the channel are matched; one end of the return spring 1003 stops against the valve cover 1001, and the other end stops against the valve core 1004;

[0072] Specific...

Embodiment 3

[0078] This embodiment provides a washing machine with a laundry treatment agent dispensing device as described in Embodiment 1 or Embodiment 2, including a water inlet valve and a water collection box. The water inlet valve includes a first water outlet control port connected to the water collection box and a communication The second water outlet control end of each water inlet end of the delivery device, each pressure relief end and each liquid outlet end of the delivery device are respectively connected to the water collection box;

[0079] Preferably, the washing machine further includes a storage box for storing the laundry treatment agent, and each liquid inlet end of the injecting device is connected to the storage box.

[0080] In the control method of the washing machine in this embodiment, when it is necessary to inject a certain laundry treatment agent, the washing machine controls the laundry water to enter the water inlet corresponding to the laundry treatment agen...

Abstract

The invention provides a releasing device for a clothing treating agent, a washing machine and a control method of the releasing device. The releasing device for the clothing treating agent includes ashell, the shell is internally provided with two or more hollow cavities, and a flexible separation body is installed in each hollow cavity in a sealed mode to separate each hollow cavity into a water inlet cavity and a liquid storage cavity; a water inlet end communicating with the water inlet cavity and a pressure relief end are arranged on the positions, corresponding to each hollow cavity, ofthe shell correspondingly, and each water inlet end communicates with a water inlet pipe of the washing machine; liquid discharging ends communicating with the liquid storage cavities are arranged onthe positions, corresponding to the hollow cavities, of the shell correspondingly, and the liquid storage cavities are filled with the clothing treating agent; and incoming water of the washing machine enters the water inlet cavities from the water inlet ends, squeezes the flexible separation bodies to deform to the liquid storage cavities, and discharge the clothing treating agent holding in theliquid storage cavities from the liquid discharge ends. According to the releasing device for the clothing treating agent, it can be ensured that residue is avoided in the adding processes of variousdetergents and nursing agents, the problem that the different detergents and nursing agents contaminate each other can be solved, and the washing effect of clothes is effectively improved.

Description

technical field [0001] The invention relates to the technical field of automatic injection of laundry treatment agent for washing machines, in particular to a laundry treatment agent injection device, a washing machine and a control method thereof. 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 ...
