Description
Technical field
It is particularly a kind of for detergent on washing machine and care agent the invention belongs to the liquid dispensing apparatus in electrical equipment
Delivery device.
Background technology
At present, the dispensing of the electrical equipment detergent such as existing washing machine of in the market be by being manually added in washing tube or
Inside the detergent case that detergent is stored in the electrical equipment such as washing machine in advance, then it will be washed by water punching or other method
Agent is washed to deliver into washing tubes of electrical equipment such as washing machines.The dispensing of this detergent depends on artificial control, and washes every time
It will be delivered manually when washing, the amount delivered every time is all different.Demand and expanding economy with market, in electricity such as washing machines
The device delivered automatically is used in device equipment it is with a kind of inevitable trend, and can be adjusted automatically according to washing weight difference
The injected volume of detergent is saved, such client is in use without will add detergent every time, but also can be in laundry
Substantial amounts of detergent is disposably deposited in the electric equipments such as machine.
It is to use peristaltic meatering pump, metering gear that the electrical equipment such as the washing machine of automatic release device are applied on existing market
Pump, piston pump etc. realize automatic dispensing.Because the viscosity of detergent is the conversion varied with temperature with season and is changed, often
The detergent viscosity of kind of brand is also different, so precision during its dispensing is also different, and pump it is complicated, be manufactured into
This height, in washing facility, non-used time detergent easily lumps in pump for a long time.
At present, the Chinese invention patent document such as Application No. 200910152768.x discloses a kind of liquid detergent
Delivery device, the delivery device has constant volume device, can constant volume accurately deliver, it has the valve that is made up of valve A and valve B
Setting room in body, valve body, valve body is externally provided with water outlet nozzle, and intake nozzle, feed liquor nozzle and air nozzle, valve body are provided with valve A, valve B,

The valve ball of water, valve ball constitutes valve C with valve seat C, and water outlet nozzle is connected by valve A with constant volume chamber, and feed liquor nozzle is by valve B with determining
Room is connected, and air nozzle is connected by valve C with constant volume chamber, although the invention can accomplish quantitative dispensing, in practice, including this
Existing detergent throwing device including detergent throwing device also exists following not enough：
1st, the valve in constant volume device and constant volume device controls detergent injected volume completely, causes the structure of constant volume device excessively multiple
Miscellaneous, manufacturing cost is high, and precision is low, easy to block, and is repaired after blocking and more change clothes shield agent switching valve inconvenience.
2nd, sealed by the valve in constant volume device, sealed precision is not high.
3rd, liquid detergent trough, entering water electromagnetic valve, water box, constant volume device and negative pressure generator are connected by pipeline, are led
Cause that whole detergent embarking device structure is too fat to move, covert possessive volume is big.
In addition, constantly upgrading for existing washing machine, washing machine more high-end at present is after detergent is added, also
Addition care agent is needed to be nursed.And lack rational in infrastructure in the market, and can be by detergent, care agent and water
The automatic release device fast switched.
