Description
Technical field
The present invention relates to the delivery device of liquid preparation, control device is thrown in the liquid scrubbing be particularly fitted on the electric rinsing maching of electrical washing machine, electrically dish-washing machine etc.
Background technology
In the past, the adding method using the electric liquid detergent (or softener, softening agent, bactericidal liquid etc.) of washing facility such as the electrical washing machine of liquid detergent, electrically dish-washing machine is that the liquid detergent that user will throw in leaves the receptacle of specifying in advance in, and washing facility to be rushed by water according to washing course or the method for other machineries is punched into washtub them.This method, the injected volume of washing agent depends on the randomness that user operates, and each washing process all needs to add washing agent to receptacle.Along with constantly going forward one by one of detergent liquid, in washing facility, disposable volume washing agent of depositing is a kind of application trend, such user can throw in a certain amount of washing agent as required in washing process, not only can reduce the troublesome poeration of user, according to the difference of washings kind and amount, automatically can also regulate cleaning solution injected volume.So washing facility configuring detergent embarking device is a kind of developing direction.
Investigate existing technology, have following example.The opening time liquid detergent be filled in container being applied to certain pressure control valve by air pump disclosed in Japanese Unexamined Patent Publication 61-172594, thus control washing agent injected volume.Passing through completely for another example disclosed in JP 2000-334197 applies air pressure to the liquid detergent examination in container, and washing agent is extruded from container.These schemes need user after liquid detergent trough fills washing agent, groove lid to be sealed completely.If there is poor sealing, the pressure of pump will leak.Even if the pressure of pump is the same, the flowing velocity of liquid detergent under same pressure of different viscosities can be different, causes input inaccurate.The noise of pump also affects the noise specification of washing facility in addition.
In Chinese market, disclosed technical scheme also has at the bottom of washing facility placement liquid scrubbing case, and the pressure produced by gear pump is washing liquid force feed or be attracted to the water box being positioned at washing facility top, then inputs washtub.Its gear pump of this scheme is often dipped in washing agent, when washing agent is finished, in pump the washing agent drying and consolidating that remains, the rotation that very large damping hinders gear pump middle gear can be produced when reusing.And the control of the work noise of gear pump to washing facility noise specification also has adverse effect.The program also exists because washing agent viscosity fluctuation causes the input error problem thrown in speed difference and produce besides.
