Description
Technical field
The present invention relates to liquid dispensing apparatus, be particularly fitted to the detergent throwing device on the electric rinsing maching of electrical washing machine, electrically dish-washing machine etc.
Background technology
In the past, use the detergent additive of the electric washing facilitys such as the electrical washing machine of liquid detergent, electrically dish-washing machine (as washing agent, softener, softening agent, bactericidal liquid etc.) adding method be that the liquid agent that user will throw in leaves the receptacle of specifying in advance in, washing facility to be rushed by water according to washing course or the method for other machineries is punched into cylindric washer them.The injected volume of this method depends on the operation of user, and each washing process needs to add washing agent to receptacle simultaneously.Along with the continuous fluidization of washing agent, disposable volume washing agent of depositing is in machine intimate, throw in the troublesome poeration that portion washes agent not only can reduce user in washing procedure as required, according to the difference of washings kind and amount, automatically can also regulate washing agent injected volume.So washing facility needs the device that washing agent is thrown in automatically.
Investigate existing technology, have following example.Disclosed in Japanese Unexamined Patent Publication 61-172594, by air pump, certain pressure is applied to the liquid detergent be filled in container, the opening time of control valve thus control the technology of washing agent injected volume.Passing through completely for another example disclosed in JP 2000-334197 applies air pressure, the technology that liquid agent extrudes from container to the liquid detergent examination in 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 detergent box, and the pressure produced by gear pump is washing agent force feed or be attracted to the water box being positioned at washing facility top, then inputs washtub.This scheme gear pump is often dipped in washing agent, and when washing agent is finished and occurs dry, the washing agent solidified can produce the gear action that very large damping hinders gear pump.The work noise of gear pump can affect the control of the noise specification of washing facility equally.The same program also exists and to fluctuate the input precision problem that the input speed difference that causes produces because washing fluid viscosity.
Comprehensive above disclosed technology, adopts air pump press-in to provide power, there is the sealing leak of detergent tank lid and liquid detergent viscosity change causes the inaccurate problem of injected volume.Adopt the way of contact of similar gear pump to provide to washing agent to there is liquid detergent during mobilization dynamic and solidify the problem causing pump to block.
Japanese Unexamined Patent Publication 11-019391 provides a kind of scheme, a water pump is set in washing machine, water in pump handle washing machine washtub or the water in bathing pool are drawn on the pipeline in washtub and arrange a nozzle, nozzle has depression generator, while pumping water, utilize the suction function of nozzle, washing agent is sucked main current, puts in washtub after mixing.The power that this technology provides avoids the sealing problem of motive power of air pump scheme and the problem of solidification of gear pump scheme.But the prerequisite of the program arranges the water pump providing constant pressure, and cost compare is high.
CN201258409Y utilizes current to produce negative pressure device equally, but propose and utilize the current of running water to produce negative pressure, but the size of negative pressure and discharge relation are very large, when the water inlet of direct use washing facility electromagnetic valve produces 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 the program proposes to arrange measuring box between negative pressure device and detergent box, shutoff valve 1-1 and valve 1-2, open valve 1-3 and valve 1-4 to make to produce vacuum in measuring box, then shutoff valve 1-3 and 1-4, open valve 1-2, rely on vacuum residual in metric space to make washing agent flow into measuring box, then shutoff valve 1-1 opens valve 1-2,1-3,1-4, and the negative pressure relying on current to produce is attracted to the washing agent in measuring box in water box goes.
The program proposes the negative pressure that causes of current size that embodiment 1 exists and fluctuate the solution of the washing agent input precision problem caused.But in the program, measuring box filled by washing agent is carry out when negative pressure source and measuring box space cut off, negative pressure remaining in measuring box is relied on to attract washing agent, when negative pressure is not enough, metric space can not be filled, and causes throwing in the not high problem of precision and occurs; Actual conditions are, when measuring box and this negative pressure source lead to, measuring box absolutely notly reaches so-called vacuum, more why not when measuring box and vacuum source cut off, though now measuring box exists negative pressure, but still there is 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 washing agent in measuring box in addition to rely on negative pressure to be attracted in main current to go, washing agent all can be had between valve to pipeline to remain, these washing agent concentrate or can hinder the flowing of washing agent after solidifying, and finally may affect input effect again.
The detergent embarking device of the 200910152768.X that the applicant proposes, solves the problems referred to above, but there is following problem:
1) constant volume valve, negative pressure generator, detergent box is respectively different parts, and centre realizes connecting of each several part with flexible pipe.But the program needs to install a lot of tube connectors, the flexible pipe be particularly connected with detergent box is difficult to choose in material can resistance to various chemical composition (surfactant, disinfectant etc. compared with Strong oxdiative performance), occur that tube connector is aging when breaking, there is the problem that washing agent leaks.Overall pipeline connects too much, and cause device stream complicated, cost is also higher.
2) capacity of this device constant volume is relevant with constant volume line, and when constant volume device delivery port position is higher than constant volume chamber bottom surface, constant volume space is the space arrived above constant volume chamber between constant volume device delivery port plane, and constant volume chamber can not be utilized completely.
3) when constant volume chamber is emptying, draining drop is little, and emptying time is long, causes throwing in excessive cycle.
4) detergent box and water box are arranged separately, take up room large.

The operation principle of apparatus for feeding liquid detergent of the present invention is described below in conjunction with accompanying drawing:
Load the user of the washing facility (such as washing machine) of this delivery device when needs liquid delivery washing agent, horizontal direction draws detergent box 9, detergent box is drawn out from water box 2, and user can add mouth 95 to the washing agent of detergent box and pour washing agent into.After washing agent is filled, then detergent washing agent box is back into inside water box, and water box joint 70 and detergent box liquid outlet 94 are tightly connected.
When needing putting detergent, be energized to the solenoid B of electromagnet water supply valve 1, electromagnetic water inlet valve B opens, the water inlet that running water flows to by water outlet B 103 negative pressure generator 4 be formed on water box 2 upper shell 24 chews 42, current are chewed by water inlet, contraction mouth 44 again in negative pressure generator flows to reservoir chamber 43, 2 li, water box is flowed out to by gap 46 after full water in reservoir chamber, underbalance effect is produced because current are amplified by cross section after described contraction mouth, it is low that the pressure chewing 41 through negative pressure gas port 45 places with negative pressure water outlet can chew the pressure at flow export place than water outlet, when flow export is to atmosphere opening, the pressure at negative pressure gas port place can form negative pressure lower than atmospheric pressure.Because reservoir chamber overfall position is higher than the top edge 441 of contraction mouth, in water inlet process contraction mouth can surround by the water in reservoir chamber, outside air can not be inhaled into inside negative pressure gas port and cause negative pressure to be lost.
The size of this negative pressure is relevant with the speed of current, and water velocity is relevant with water flow pressure again.
First explanation liquid detergent input A-stage-
Each valve state (see Fig. 8):
The electromagnetic water inlet valve A of electromagnet water supply valve 1: close
The electromagnetic water inlet valve B of electromagnet water supply valve 1: open
The valve A307 of constant volume device 3: open, the valve B308 of constant volume device 3: close
The valve C312 of constant volume device 3: open
The negative pressure gas port 45 of negative pressure generator 4 connects with the vacuum aspiration port 303 of constant volume device 3, and owing to not having water in the constant volume chamber 306 of constant volume device, valve ball I311 falls within valve seat C309 without buoyancy because of deadweight, and valve C312 is in open mode;
The unlatching of electromagnetic water inlet valve B makes current enter water box 2 through negative pressure generator 4, and the negative pressure that current produce just is delivered to the constant volume chamber 306 of constant volume device.The valve A307 controlling constant volume device is in open mode, the valve B308 of constant volume device is in closed condition, mixed solution outlet 313 and the mixed solution of water box of constant volume device export 27 and connect also and atmosphere, and the negative pressure of negative pressure generator 4 exports 313 to atmosphere opening by the mixed solution of constant volume device.Because valve B308 is in closed condition, the washing agent in detergent box is closed can not flow to constant volume chamber by valve B.Under this state, constant volume chamber is in negative pressure state always.
Secondly explanation washing agent stowing operation-
Each valve state:
Electromagnetic water inlet valve A: close
Electromagnetic water inlet valve B: open
The valve A of constant volume device: close
The valve B of constant volume device: open
The valve C of constant volume device: open
Control to open the valve B of constant volume device, close the valve A of constant volume device, like this, open-minded between the constant volume chamber 306 of constant volume device and inlet 301, the mixed solution of constant volume chamber and constant volume device is closed between exporting 313; The water inlet 314 of constant volume device connects with electromagnetic water inlet valve A, electromagnetic water inlet valve A is in closed condition, the water inlet of constant volume device and outside are in pressure closed condition, and electromagnetic water inlet valve B be in open mode can continue produce negative pressure, this negative pressure is delivered to the constant volume chamber of constant volume device constantly, and the washing agent in liquid detergent box just enters constant volume chamber 306 by the sucking action of constant volume chamber negative pressure by inlet 301.
Again illustrate be filled with rear waiting process-
Each valve state:
Electromagnetic water inlet valve A: close
Electromagnetic water inlet valve B: open
The valve A of constant volume device: close
The valve B of constant volume device: open
The valve C of constant volume device: close
When liquid detergent is filled with constant volume chamber, the effect of valve ball I311 liquid body buoyancy upwards contacts with constant volume chamber valve seat C309, and valve C312 is closed, and constant volume chamber and negative pressure source cut off, and liquid detergent no longer enters constant volume chamber.
Then illustrate washing agent rush defeated process-
Each valve state:
Electromagnetic water inlet valve A: open
Electromagnetic water inlet valve B: close or open
The valve A of constant volume device: open
The valve B of constant volume device: close
The valve C of constant volume device: close
Constant volume chamber is filled with and after waiting process terminates, by the valve B of automatically controlled closedown constant volume device, open the valve A of constant volume device, open electromagnetic water inlet valve A, running water flow in constant volume chamber 306 by the water outlet A 102 of electromagnet water supply valve and the water inlet 314 of constant volume device, flows out to the mixed solution outlet 27 of water box after the liquid detergent in constant volume chamber is mixed by running water together with running water from the mixed solution outlet 313 of constant volume device.
Finally explanation constant volume chamber evacuation procedure-
Each valve state
Electromagnetic water inlet valve A: close
Electromagnetic water inlet valve B: close
The valve A of constant volume device: open
The valve B of constant volume device: close
The valve C of constant volume device: open
After flushing terminates, electromagnetic water inlet valve B closes, because the drainage by suction mouth 41 of negative pressure generator is lower than contraction mouth lower limb 442, water in reservoir chamber 43 is emptying by drainage by suction mouth 41, make contraction mouth 44 pairs of atmosphere openings of negative pressure generator, electromagnetic water inlet valve A closes, so the vacuum aspiration port 303 of constant volume device is also in atmosphere opening state, because mixed solution outlet 27 height of water box is lower than constant volume chamber bottom surface 3061, liquid in constant volume chamber is just under the effect of deadweight, discharged by mixed solution outlet 313, until the liquid height in constant volume chamber drops to constant volume chamber bottom surface less than 3061.
Flow pipe part between the outlet of the mixed solution of constant volume device and the mixed solution outlet of water box also can be arranged on above constant volume chamber by actual product, as long as the position of the mixed solution outlet 27 of final water box is lower than constant volume chamber bottom surface 3061, the mixed solution of constant volume chamber inside can be drained by siphon.
When the height of the mixed solution outlet 27 of actual product upper water box is lower than constant volume chamber bottom surface more distance (generally reaching more than 20cm), the velocity of discharge of the mixed solution in constant volume chamber will be accelerated, and shortens the cycle time of throwing in.
So once input action can throw in the liquid detergent that constant volume chamber volume (such as 20CC) is measured, if need more, can carry out 1 time, 2 times again ... such several is thrown in, and throws in the liquid detergent of constant volume chamber cubical content multiple.
Also can change the size in constant volume space, such as be set to 10CC, so just can throw in the liquid detergent of 10CC or its times of quantity.
In whole washing agent launch process, the state of each valve is as follows:
| Movement content | Electromagnetic water inlet valve A | Electromagnetic water inlet valve B | Constant volume chamber valve A | Constant volume chamber valve B | Constant volume chamber valve C | |
| 1 | Initial stage | Close | Open | Open | Close | Open |
| 2 | Washing agent filling | Close | Open | Close | Open | Open |
| 3 | Fill rear wait | Close | Open | Close | Open | Close |
| 4 | Rush defeated | Open | Open or close | Open | Close | Close |
| 5 | Emptying | Close | Close | Open | Close | Open |
From the above, this device of the present invention, no matter tap water hydraulic is in the minimum (0.02MPa) of conventional criteria, and still the highest limit (1.0MPa), can throw in the liquid detergent of constant volume chamber cubical content integral multiple exactly.
In the present invention, the valve A of constant volume device and the implementation method of valve B can be realized by a three-way magnetic valve door, and time by-pass valve control B closes, valve A is in open mode, and time by-pass valve control B is in and opens, valve A is in closed condition.
Also can realize the control of valve B with an electromagnetic valve, be realized the control of valve A by other valve such as ball valve.
In this case, multi-channel electromagnetic valve (valve B1, B2......) can also be set for valve B and control, realize the switching input control of multichannel washing agent.
For preventing negative pressure in running water water pipe by the washing agent suck-back inhaled in detergent box to water supply pipe, reverse stop valve can be set in the water inlet of the water inlet of constant volume device or negative pressure generator.
When user pulls out sink 9 inside water box 2, for preventing washing agent from flowing out from detergent box outlet, in detergent box exit, reverse stop valve can be installed.
Foregoing invention solves in the past that detergent embarking device pipeline is many, system complex, the solution below constant volume chamber constant volume line can not be emptying, and constant volume space can not use completely, the problem that emptying time is long, and detergent box is separated with water box and arranges the large problem of duty.
