Description
Technical field
The utility model relates to the delivery device of liquid preparation, and control device is thrown in the liquid scrubbing being particularly fitted on the electric rinsing maching of electrical washing machine, electric dish-washing machine etc.
Background technology
In the past, using the adding method of the liquid detergent (or softener, softening agent, bactericidal liquid etc.) of the electric washing facilitys such as the electrical washing machine of liquid detergent, electric dish-washing machine is that the liquid detergent that user will throw in leaves the receptacle of appointment in advance in, and the method that washing facility rushes by water according to washing course or other are mechanical is punched into washtub washing washing agent.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.Continuous enhancement along with detergent liquid, in washing facility, the disposable volume washing agent of depositing is a kind of application trend, user can throw in as required a certain amount of washing agent wherein in washing process like this, this not only can reduce user's troublesome poeration, can also, according to the difference of washings kind and amount, automatically regulate washing agent injected volume.So configure detergent embarking device on washing facility, it is a kind of developing direction.
Investigate existing technology, have following example.As disclosed in TOHKEMY 61-172594 the liquid detergent being filled in container is applied to the opening time of certain pressure control valve by air pump, thereby control washing agent injected volume.For another example JP 2000-334197 is disclosed applies air pressure by the liquid detergent in container completely, and washing agent is extruded from container.These schemes need user after liquid detergent trough is filled with 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 the liquid detergent of different viscosities under same pressure can be different, causes throwing in inaccurate.The noise of pump also affects the noise index control of washing facility in addition.
In Chinese market, disclosed technical scheme also has in the bottom of washing facility and places liquid scrubbing case, and the pressure producing by gear pump is washing liquid force feed or attract to the water box that is positioned at washing facility top, then inputs washtub.Its gear pump of this scheme is often dipped in washing agent, and when washing agent is finished, residual washing agent drying and consolidating in pump, can produce the rotation that very large damping hinders gear pump middle gear while reusing.And the work noise of gear pump also has adverse effect to the control of washing facility noise index.This scheme also exists because washing agent viscosity fluctuation causes and throws in the input error problem that speed difference produces besides.
Comprehensive above disclosed technology, adopts air pump to be pressed into power is provided, and exists detergent tank lid sealing leak and liquid detergent viscosity to change and causes the inaccurate problem of injected volume.While adopting the way of contact of similar gear pump to provide mobilization dynamic to washing agent, exist liquid detergent to solidify the problem that causes pump to stop up.
Japanese kokai publication hei 11-019391 provides a kind of scheme, a water pump is set in washing machine, water in pump handle tub of washing machine or the water suction streams in bathing pool are crossed the nozzle arranging on the pipeline in washtub, on nozzle, there is depression generator, when pumping water, utilize the suction function of nozzle, cleaning solution is sucked into main current, after mixing, put in washtub.The power that this technology provides has been avoided the sealing problem of motive power of air pump scheme and the residual washing agent solidification problem of gear pump scheme, but the prerequisite of this scheme is that the water pump that constant pressure is provided is set, and cost compare is high like this.
CN201258409Y document discloses the device that utilizes equally current to produce suction function, but what propose is to utilize the current of running water to produce negative pressure, and the relation of the size of negative pressure and tap water pressure and flow is very large, therefore while directly using the water inlet of electromagnetic valve in washing facility to produce negative pressure, the negative pressure fluctuation range producing can be very large, and the input precision of washing agent is difficult to control.
The embodiment 2 of this scheme proposes, between negative pressure device and detergent box, measuring box is set, shut off valve one and valve two, open valve three and valve four and make generation vacuum in measuring box, then shut off valve three and valve four, open valve two, rely on residual vacuum in metric space to make liquid detergent flow into measuring box, then shut off valve one is opened valve two, valve three, valve four, and the negative pressure that relies on current to produce attracts the washing agent in measuring box in water box.
This scheme has proposed embodiment 1 and has existed current size to cause the solution of the washing agent input error problem that negative pressure fluctuation causes.But in this scheme, washing agent filling measuring box is the in the situation that of negative pressure source and the cut-out of measuring box space, relies on negative pressure remaining in measuring box to attract washing agent, and during negative pressure deficiency, metric space can not be filled, and causes throwing in the problem appearance that precision is not high; Actual conditions are, when measuring box and this negative pressure source lead to, measuring box is the absolutely not so-called vacuum that reaches, more why not when measuring box and vacuum source cut off, though now measuring box exists negative pressure, but still have certain air pressure (having a certain amount of air), along with the filling of liquid detergent, measuring box remaining space diminishes, and that a certain amount of air of existence is compressed, the negative pressure of measuring box remaining space disappears, and now just can not recharge washing agent; In measuring box poor sealing situation, be just more a problem.Be filled in addition washing agent in measuring box and rely on negative pressure to attract again in main current, all can have washing agent residual between from valve to pipeline, these washing agent concentrated or fixed after can hinder flowing of washing agent, finally may affect input effect.
