Description
Technical field
The present invention relates to liquid dispensing apparatus, particularly be fitted to the detergent throwing device on the electric rinsing maching of electrical washing machine, electric dish-washing machine etc.
Background technology
In the past; The liquid detergent that uses electric washing facilitys such as the electrical washing machine of liquid detergent, electric dish-washing machine is (like washing agent; Softener; Softening agent, bactericidal liquid etc.) liquid detergent that the adding method person of being to use will throw in leaves the receptacle of appointment in advance in, and washing facility dashes through water according to washing course or other mechanical methods are punched into cylindric washer to them.The injected volume of this method depends on user's operation, and simultaneously each washing process need add washing agent to receptacle.Continuous fluidization along with washing agent; The disposable volume washing agent of depositing is in machine intimate; Throw in the troublesome poeration that the part washing agent not only can reduce the user in the washing procedure as required, can also be according to washings kind and amount different, regulate the cleaning solution injected volume automatically.So device that needs cleaning solution to throw in automatically on the washing facility.
Investigate existing technology, following example is arranged.As TOHKEMY 61-172594 is disclosed the liquid detergent that is filled in the container is applied certain pressure through air pump, thus the technology of the time of opening of control valve control washing agent injected volume.Special for another example to open 2000-334197 disclosed fully through examination applies air pressure to the liquid detergent in the container, the technology that extrudes liquid agent from container.These schemes need the user after the liquid detergent groove is filled with washing agent, to seal the groove lid fully.If poor sealing, the pressure of pump will leak.Even the pressure of pump is the same, the flowing velocity of the liquid detergent of different viscosities under same pressure can be different, causes throwing in inaccurate.The noise of pump also influences the noise index of washing facility in addition.
Disclosed technical scheme also has at the bottom of washing facility placement washing lotion box on the Chinese market, and the pressure that produces through gear pump perhaps is attracted to the water box that is positioned at the washing facility top to the cleaning solution force feed, imports washtub again.This scheme gear pump often is dipped in the cleaning solution, and cleaning solution uses up when drying takes place, and the cleaning solution that solidifies can produce the gear action that very big damping hinders gear pump.The work noise of gear pump can influence the control of the noise index of washing facility equally.Same this scheme also exists because of washing the fluid viscosity input precision problem that the input speed difference that causes produced that fluctuates.
Disclosed technology more than comprehensive adopts air pump to be pressed into power is provided, and exists lid sealing leak of washing agent groove and liquid detergent viscosity to change and causes the inaccurate problem of injected volume.Exist liquid detergent to solidify when adopting the way of contact of similar gear pump mobilization dynamic to be provided and cause the pump blocking problem to washing agent.
Japanese kokai publication hei 11-019391 provides a kind of scheme; A water pump is set in washing machine, and water in the pump handle washing machine washtub or the water in the bathing pool are drawn on the pipeline in the washtub nozzle are set, and have depression generator on the nozzle; When pumping water; Utilize the suction function of nozzle, suck main current to cleaning solution, put in the washtub after the mixing.The power that this technology provides has been avoided the sealing problem of air pump power scheme and the problem of solidification of gear pump scheme.But the prerequisite of this scheme is that the water pump that constant pressure is provided is set, and cost is than higher.
CN201258409Y utilizes current to produce negative pressure device equally; But proposed to utilize the current of running water to produce negative pressure; And the size of negative pressure and discharge relation are very big; When directly using the water inlet generation negative pressure of washing facility electromagnetic valve, the negative pressure fluctuation range of generation can be very big, and the input precision of washing agent is difficult to control.
The embodiment 2 of this scheme proposes between negative pressure device and Box for detergent, to be provided with the metering box; Shut off valve 1-1 and valve 1-2 open valve 1-3 and valve 1-4 and make generation vacuum, shut off valve 1-3 and 1-4 then in the metering box; Open valve 1-2; Residual vacuum makes cleaning solution flow into the metering box in the dependence metric space, and shut off valve 1-1 opens valve 1-2,1-3,1-4 then, and the negative pressure that relies on current to produce is attracted to the cleaning solution in the metering box in the water box goes.
This scheme has proposed the solution that cleaning solution that negative pressure fluctuation that current size that embodiment 1 exists causes causes is thrown in precision problem.But cleaning solution filling metering box is under the situation of negative pressure source and the space cut-out of metering box, to carry out in this scheme; Rely on negative pressure remaining in the metering box to attract cleaning solution; When negative pressure was not enough, metric space can not be filled, and caused throwing in the not high problem of precision and occurred; Actual conditions are that when metering box and this negative pressure source led to, the metering box was the absolutely not so-called vacuum that reaches; More why not when the metering box cuts off with vacuum source, there is negative pressure though measure box this moment, but still at air pressure (a certain amount of air is arranged) necessarily; Along with the filling of liquid detergent, metering box remaining space diminishes, and that air in certain amount of existence is compressed; The negative pressure of metering box remaining space disappears, and just can not recharge washing agent this moment; Under the metering box poor sealing situation, just more be a problem.Be filled in the cleaning solution of metering in the box in addition and rely on negative pressure to be attracted to again in the main current to go, all can have cleaning solution residual between from the valve to the pipeline, these cleaning solutions concentrate or solidify after can hinder flowing of cleaning solution, finally possibly influence the input effect.
