Fabric softener putting device used for washing machine

Abstract

The invention relates to a fabric softener putting device used for a washing machine. The fabric softener putting device used for the washing machine comprises a water inlet solenoid, a liquid storage box, a fixed capacity container, a fabric softener switch valve and a negative pressure generator. The liquid storage box is provided with a water box and a laundry detergent / fabric softener storage chamber. The fixed capacity container is provided with a laundry detergent inlet, a negative port and a drain outlet. The water inlet solenoid is provided with a water inlet, a first water outlet having a solenoid and a second outlet having a solenoid. The second water outlet is connected with the negative pressure generator, and a negative pressure port of the negative pressure generator is connected with the negative pressure port of the fixed capacity container. The fabric switch valve comprises a water inlet, a laundry detergent inlet, a fabric softener inlet, and a liquid outlet. The laundry detergent / fabric softener storage chamber is connected with the fabric softener switch valve. The water inlet solenoid is connected with the water inlet of the fabric softener switch valve. The fabric softener switch valve is connected with the laundry detergent inlet of the fixed capacity container, and the drain outlet of the fixed capacity container is connected with the water box. The putting device is low in manufacturing cost, high in precision, convenient to switch, and the fabric softener hardly jam.

Description

technical field [0001] The invention belongs to a liquid distributing device in an electrical appliance, in particular to a detergent and care agent dispensing device for a washing machine. Background technique [0002] At present, the detergents for washing machines and other electrical appliances in the market are manually added to the washing tub or stored in the detergent storage boxes of washing machines and other electrical appliances in advance, and then the detergent is injected by water flushing or other methods. into the washing tub of washing machines and other electrical appliances. The delivery of this detergent depends on human control, and it must be manually delivered every time it is washed, and the amount of delivery is different each time. With the demand of the market and the development of the economy, it is an inevitable trend to use automatic feeding devices in washing machines and other electrical equipment, and the amount of detergent can be automat...

AI Technical Summary

Problems solved by technology

[0005] 1. The fixed container and the valve in the fixed container completely control the detergent dosage, which makes the structure of the fixed container too complicated, high manufacturing cost, low precision, easy to block, and it is inconvenient to maintain and replace the detergent switching valve after blockage

[0006] 2. Relying on the valve seal in the fixed container, the sealing accuracy is not high

[0007] 3. The liquid detergent tank, water inlet solenoid valve, water box, fixed container and negative pressure generator are all connected through pipelines, resulting in a bloated structure of the entire detergent automatic dispensing device, which occupies a large volume in disguise

However, the current market lacks an automatic feeding device that has a reasonable structure and can quickly switch detergent, care agent and water.
