Problems solved by technology

[0002]At present, the device for injecting liquid detergent into the washing machine is realized by various pumps. There are two commonly used devices, one is the liquid washing machine integrated with the washing machine The auxiliary box needs to be molded separately; the other is a split type, which needs to be installed on the washing machine. These two methods have caused unnecessary troubles to production and processing.

Embodiment 1

[0033] figure 1 Shown is the embodiment of the pressure test in various parts of the liquid washing aid device, as shown in the figure, it includes: a tap water outlet 12 connected with tap water, a water inlet pipe 14 leading to the main waterway 15 and the auxiliary waterway 16, installed in the auxiliary waterway 15 The pressure control device 6 and the auxiliary control valve 5 on the upper, the control valve 8 and the main control valve 10 installed on the main waterway 16. The anti-backflow device 4 installed on the bypass 17, the metering pump 2 connected to the liquid washing aid box 1, the outlet pipeline 18 is connected to the water inlet pipeline of the washing machine, and the liquid washing aid passes through the washing machine water inlet electromagnetic valve 11 of the washing machine Enter in the washing machine 13. In order to facilitate the test, a pressure gauge 3 and a pressure gauge 9 are respectively installed on the secondary waterway 15 and the main w...

Embodiment 2

[0047] combine figure 2 Specifically illustrate a kind of device embodiment 2 that automatically injects liquid detergent into the washing machine, it comprises: the tap water outlet 12 that is connected with tap water, draws the water inlet pipeline 14 of main waterway 15, auxiliary waterway 16, is installed on the auxiliary waterway 15 The pressure control device 6 is a control valve 8 installed on the main waterway 16. The anti-backflow device 4 installed on the bypass 17, the metering pump 2 connected with the liquid washing aid box. Before the washing machine starts working, set all pipelines to be blocked, turn on the water inlet button of the washing machine, turn on the pressure control device 6 to the specified value, and after the water flow is consistent, start the metering pump 2, and the anti-backflow device 4 is in the open state to ensure that the bypass 17 is unobstructed , inject a certain amount of liquid detergent. After the liquid washing aid is injected...

Embodiment 3

[0051] Such as image 3 , the researchers of the present invention believe that the pressure control device 6 can be a shrink tube, and in the present invention, the definition of the shrink tube is as follows, even if the shrink tube in the present invention is the same as the technical term in other technical fields, the present invention According to the self-definition, in the present invention, the shrinking tube refers to a passage with a small aperture, which can be a thin tube or a small micropore, through which the secondary The pressure of the waterway 15 drops to the specified range.

[0052] Specifically speaking, when the control valve 8 is closed, the water flow from the secondary waterway 15 can smoothly open the washing machine water inlet electromagnetic valve 11, for example, when the tap water pressure of the auxiliary waterway 15 is about 0.022 MPa, the washing machine water inlet solenoid valve 11 can be opened, Therefore, the pressure control device 6 ca...

Abstract

The invention provides a method and device for injecting a liquid detergent assistant via a water inlet electromagnetic valve of a washing machine. The method comprises the steps that one end of a water inlet pipeline is connected to a tap faucet, the other end is connected to an assistant waterway and a main waterway, and the assistant waterway and the main waterway are connected to a water outlet pipeline; a pressure control device is disposed on the assistant waterway, and a bypass is disposed on the assistant waterway between the pressure control device and the water outlet pipeline and connected to a liquid detergent assistant box; the main waterway and the assistant waterway are closed, the washing machine is switched on, and then the assistant waterway is opened; the liquid detergent assistant is automatically injected into the assistant waterway and flows into the washing machine via the water inlet electromagnetic valve along the assistant waterway and the water outlet pipeline; and when the amount of liquid detergent assistant reaches a designated dosage, the main waterway can be opened for water injection, and the washing machine starts working when a designated water level is reached. The method and the device provided by the invention have the advantages that the device used for injecting the liquid detergent assistant is effectively connected to the water inlet electromagnetic valve of the washing machine, so that a current situation of the washing machine is not broken; and processing is simple, and operations are convenient.

Description

technical field [0001] The invention relates to a method and device for injecting liquid detergent into a washing machine by utilizing a water inlet electromagnetic valve of the washing machine. Background technique [0002] At present, the device for injecting liquid detergent into the washing machine is realized by various pumps. There are two commonly used devices. One is the liquid detergent box integrally formed with the washing machine, which needs to be molded separately; As a body, it needs to be installed on the washing machine, and these two methods have caused unnecessary troubles to production and processing. [0003] In view of this, how to design a method and device capable of injecting liquid washing aid without changing the current situation of the washing machine is the object of the present invention. Contents of the invention [0004] The main purpose of the present invention is to provide a method for injecting liquid washing aid by using the water inl...
