The program controller controls the opening and closing of each valve port.

The liquid storage supply valve 2-2 is connected to the liquid storage tank 1 through the washing liquid input pipe 5, and the liquid storage tank 1 is flexibly connected to the washing liquid input pipe 5, which is detachable and convenient for users to clean; Vent valve port 2-5, vent valve port 2-5 is connected with a vent pipe 8, vent valve port 2-5 can make outside air smoothly enter in the valve cavity 2-1, prevent the liquid in the valve cavity 2-1 from flowing out simultaneously, or allow A small amount of liquid flows out, which can ensure that the liquid in the valve cavity 2-1 flows out through the water outlet valve port 2-3 smoothly.

When the washing liquid is put in, the washing liquid enters the valve cavity through the liquid storage supply valve 2-2, and the flow rate through the liquid storage supply valve 2-2 is proportional to the opening time. Through experiments, it can be determined that the liquid storage supply valve 2-2 and the valve cavity In this way, by controlling the opening time of the liquid storage supply valve 2-2, it can be ensured that the valve cavity will be filled once it is opened. After the washing liquid fills the valve cavity, tap water will enter through the water inlet pipe 7 from the water inlet valve port 3-1 on the one hand. In the valve cavity 2-1, on the other hand, through the connecting pipe 4, it is flushed into the valve cavity 2-1 from the liquid stop valve port 2-4, and then flows out from the outlet valve port 2-3. If a large amount of washing liquid needs to be added, only It is necessary to adjust the entire control process and repeat it in sequence, so as to realize the automatic delivery of quantitative washing liquid.

Embodiment 2 is a washing machine with the washing liquid automatic dispensing device described in Embodiment 1, including a program controller, a liquid storage tank 1, a liquid inlet solenoid valve 2 and a water inlet solenoid valve 3 electrically connected to the program controller. The liquid solenoid valve 2 includes a liquid storage supply valve port 2-2, a water outlet valve port 2-3 and a liquid stop valve port 2-4. The water outlet valve port 2-3 is located on the left side of the valve cavity 2-1, and the water outlet valve port 2- 3 Connect to the outlet pipe 6, the liquid storage supply valve port 2-2 is located on the upper part of the valve chamber 2-1 and connects to the liquid storage tank 1, the liquid stop valve port 2-4 is located at the bottom of the valve chamber 2-1 and connected to the water inlet pipe through the communication pipe 4 7. The water inlet valve port 3-1 of the water inlet solenoid valve 3 is located on the right side of the valve chamber 2-1, and the water inlet valve port 3-1 is a one-way valve, which ensures that tap water can enter the valve chamber 2-1 In order to prevent the liquid in the valve cavity 2-1 from flowing back into the water inlet pipe 7. The program controller controls the opening and closing of each valve port.

The liquid storage tank 1 is fixed on the washing machine, and the user can store detergents, softeners, bleaching agents and other washing liquids therein, which can be conveniently added after use.

The working process of this embodiment is as follows: firstly, the washing liquid is filled into the liquid storage tank 1, and after putting in the laundry, when the washing machine needs to put in the detergent, the program controller receives the automatic weighing sensing signal or the water level height setting value to control the washing process.
