Description
Technical field
The utility model relates to the delivery device of liquid preparation, and control device is thrown in the liquid scrubbing particularly be 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 the 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 to them.This method, the injected volume of washing agent depends on the randomness that the 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, the disposable volume washing agent of depositing is a kind of application trend, the user can throw in as required a certain amount of washing agent in washing process like this, not only can reduce user's troublesome poeration, can also, according to the difference of washings kind and amount, automatically regulate the cleaning solution injected volume.So on washing facility, the configuration detergent embarking device is a kind of developing direction.
Investigate existing technology, following example is arranged.As disclosed as TOHKEMY 61-172594 the liquid detergent be filled in container is applied to the opening time of certain pressure control valve by air pump, thereby control the washing agent injected volume.JP 2000-334197 is disclosed for another example applies air pressure by the examination of the liquid detergent in container fully, and washing agent is extruded from container.These schemes need the user after liquid detergent trough is filled with washing agent, the groove lid to be sealed fully.If there is 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 affects the noise index of washing facility in addition.
On Chinese market, disclosed technical scheme also has in the bottom of washing facility and places the liquid scrubbing case, and the pressure produced by gear pump to the water box that is positioned at the washing facility top, then is inputted washtub to washing liquid force feed or attraction.Its gear pump of this scheme often is 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 the 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 the washing agent viscosity fluctuation causes and throws in the input error problem that speed difference produces besides.
Comprehensive above disclosed technology, adopt air pump to be pressed into power be provided, and exists detergent tank lid sealing leak and liquid detergent viscosity to change and cause 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 the pump handle tub of washing machine or the water suction streams in bathing pool are crossed the nozzle arranged on the pipeline in washtub, there is depression generator on nozzle, when pumping water, utilize the suction function of nozzle, cleaning solution is sucked into to main current, put in washtub after mixing.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.
The 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 produced 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 1-1 and valve 1-2, open valve 1-3 and valve 1-4 and make in measuring box to produce vacuum, then shut off valve 1-3 and valve 1-4, open valve 1-2, rely on residual vacuum in metric space to make liquid detergent flow into measuring box, then shut off valve 1-1 opens valve 1-2,1-3,1-4, and the negative pressure that relies on current to produce attracts the washing agent in measuring box in the water box.
This scheme has proposed embodiment 1 and has existed the current size to cause the solution of the washing agent input error problem that the negative pressure fluctuation causes.But in this scheme, washing agent filling measuring box is in the situation that negative pressure source and measuring box space cut off, and relies on negative pressure remaining in measuring box to attract washing agent, and during the negative pressure deficiency, metric space can not be filled, causes throwing in the problem that precision is not high and occur; 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 there is negative pressure in measuring box, but still have certain air pressure (a certain amount of air is arranged), along with the filling of liquid detergent, the measuring box remaining space diminishes, and a certain amount of air of that 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, just more be a problem.The washing agent be filled in addition in measuring box relies on negative pressure to attract in main current again, all can have washing agent residual between from the valve to the pipeline, these washing agent concentrated or fixed after can hinder flowing of washing agent, finally may affect the input effect.
Summary of the invention
The utility model will solve the apparatus for feeding liquid detergent structure more complicated of current washing facility configuration, the input precision is not accurate enough, washing agent is the residual fixed problem such as cause that the equipment operation is obstructed easily, provide a kind of washing agent of the present utility model to throw in controller for this reason, this washing agent is thrown in the controller simple structure, and volume is little, easy to install, the interior washing agent of equipment is difficult for residual, and the input precision is high.
