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 cleaning solution 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 agent 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; But 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 cleaning solution 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.

Below in conjunction with accompanying drawing the present invention is described further.
When valve A302 and valve B303 were provided with in horizontal direction, the upper limb position of valve seat A30131 through hole is constant volume chamber constant volume maybe the start line position.Valve A and valve B are in vertical direction the time, and the position of valve seat A is constant volume chamber constant volume maybe the start line position.The height that A501 is chewed in water box 5 water inlet is equal to or less than this constant volume position maybe start line the time, and this constant volume chamber constant volume possibly be constant volume start line position in start line position.The height that A is chewed in water box water inlet is higher than this constant volume maybe start line position the time; The height that the water inlet of water box is chewed is constant volume start line position; Because the height that the water inlet of water box is chewed is lower than constant volume chamber end face, the constant volume chamber volume that forms between the altitude line that constant volume chamber end face and water box water inlet is at this moment chewed is exactly the constant volume space.
The operation principle of apparatus for feeding liquid detergent of the present invention:
The user who loads the washing facility (such as washing machine) of this delivery device throws in enough nonexpondable liquid scrubbing amount in liquid detergent groove 2; When needing to throw in washing agent, give the solenoid B energising of electromagnet water supply valve, electromagnetic water inlet valve B opens; Running water flows out to through water outlet B 103 and attracts the water inlet of generator 4 to chew 401; Current were chewed 402 o'clock through attracting contraction mouth 403 in the generator to flow to water outlet, because water flow section amplifies, it is low that the pressure of chewing 402 gas port 404 places that connect with water outlet can be chewed the pressure at flow export place than water outlet; Flow export is during to atmosphere opening, and the pressure at the gas place of chewing can be lower than atmospheric pressure and form negative pressure.The size of this negative pressure is relevant with the speed of current, and water velocity is relevant with water flow pressure again, and the evidence water flow pressure is seen accompanying drawing 1 with the negative pressure relation that is produced.
At first explain liquid detergent throw in A-stage-
Each valve state:
Electromagnetic water inlet valve A: close
Electromagnetic water inlet valve B: open
Constant volume chamber valve A: open
Constant volume chamber valve B: close
Constant volume chamber valve C: open
The gas port 404 of attraction generator is chewed 3017 with the gas of constant volume device and is linked, owing to do not have water in the constant volume device constant volume chamber 3013, valve ball 310 falls within on the bearing 30121 because of the deadweight reason, and valve C304 is in open mode;
The unlatching of electromagnetic water inlet valve B makes current get into water box 5 through attracting generator 4, and the negative pressure that current produced just is delivered to the constant volume chamber of constant volume device.Control constant volume chamber valve A302 is in open mode; The corresponding with it constant volume chamber valve B303 that must make is in closed condition; The water outlet of constant volume device chew 312 chew with water box water inlet that A501 connects and with atmosphere UNICOM, attract the negative pressure of generator 4 to chew to atmosphere opening through the water outlet of constant volume device.Because valve B is in closed condition, the washing agent in the liquid detergent groove is closed by valve B and can not be flowed to the constant volume chamber.The constant volume chamber is in negative pressure state always under this state.
Next explain the cleaning solution stowing operation-
Each valve state:
Electromagnetic water inlet valve A: close
Electromagnetic water inlet valve B: open
Constant volume chamber valve A: close
Constant volume chamber valve B: open
Constant volume chamber valve C: open
Can open constant volume chamber valve B through automatically controlled, close constant volume chamber valve A, like this, constant volume device constant volume chamber and feed liquor are open-minded between chewing 3016, and constant volume chamber and the water outlet of constant volume device are closed between chewing 312; Constant volume device water inlet is chewed 313 and is connected with electromagnetic water inlet valve A; Electromagnetic water inlet valve A is in closed condition; The water inlet of constant volume device is chewed with the outside and is in the pressure closed condition; And electromagnetic water inlet valve B is in open mode and can continues to produce negative pressure, and this negative pressure is delivered to constant volume device constant volume chamber constantly, and the washing agent in the liquid detergent groove just receives the sucking action of constant volume chamber negative pressure to chew 3016 through feed liquor and gets into constant volume chambers 3013.
Wait process after explanation is filled with again-
Each valve state:
Electromagnetic water inlet valve A: close
Electromagnetic water inlet valve B: open
Constant volume chamber valve A: close
Constant volume chamber valve B: open
Constant volume chamber valve C: close
When liquid detergent was filled with the constant volume chamber, valve ball liquid body buoyancy function upwards contacted with constant volume chamber valve seat C, and valve C304 is closed, and constant volume chamber and negative pressure source cut off, and liquid detergent no longer gets into the constant volume chamber.
As previously mentioned, the tap water hydraulic fluctuation can cause the water velocity fluctuation, thereby the negative pressure that causes attracting generator to produce changes a lot; Because the variation of this pressure causes the speed that liquid detergent flows to the constant volume chamber to fluctuate, and is set to 20cc such as the constant volume chamber, the constant volume chamber is filled with during hydraulic pressure 0.02MPa needs 20 seconds; And hydraulic pressure only needed for 5 seconds when being 1.0MPa; The shut-in time of opening with valve A according to worst condition valve B constant volume when action is set to 20 seconds, during hydraulic pressure 1.0MPa, and the initial 5 seconds C of valve place open modes; Negative pressure is entered the constant volume chamber; After 5 seconds because valve C is closed, and negative pressure can not be delivered to the constant volume chamber, so after 5 seconds between 20 seconds the washing agent in the liquid detergent groove can not get into the constant volume chamber again.
The time and the loading relation of constant volume chamber filling liquid are seen Fig. 2 under the different negative pressure.P1 refers to the negative pressure that high water flow pressure (1.0MPa) produces among the figure, and P2 refers to the negative pressure that low water flow pressure (0.02MPa) produces.
Explain then cleaning solution dash defeated process-
Each valve state:
Electromagnetic water inlet valve A: open
Electromagnetic water inlet valve B: close or open
Constant volume chamber valve A: open
Constant volume chamber valve B: close
Constant volume chamber valve C: close
After the constant volume chamber is filled with and the wait process finishes; Through the automatically controlled constant volume chamber valve B that closes; Open constant volume device valve A; Open electromagnetic water inlet valve A, the water outlet A 102 of running water through electromagnet water supply valve with the constant volume device water inlet chew 313 and flow in the constant volume chamber 3013, the indoor liquid detergent of constant volume is mixed the back by running water and chews 312 together with running water from the water outlet of constant volume device and flow out to the water inlet of water box and chew A501.
Explain at last constant volume chamber evacuation procedure-
Each valve state
Electromagnetic water inlet valve A: close
Electromagnetic water inlet valve B: close
Constant volume chamber valve A: open
Constant volume chamber valve B: close
Constant volume chamber valve C: open
After dashing defeated the end, electromagnetic water inlet valve B closes, and chews B502 to atmosphere opening owing to attract the water outlet of generator 4 to chew 402 through the water inlet of water box; Electromagnetic water inlet valve A closes; Also be in the atmosphere opening state so constant volume device gas chews 3017, because water box water inlet chews A501 and highly be equal to or less than constant volume chamber constant volume start line, the indoor liquid of constant volume is just under the effect of conducting oneself with dignity; Chew 312 through the water outlet of constant volume chamber and discharge, drop to constant volume chamber constant volume start line up to the indoor liquid height of constant volume.
So once the input action can be thrown in constant volume chamber volume and (removed the constant volume start line with the lower part; Such as 20CC) amount liquid detergent; More if desired, can carry out again 1 time, 2 times ... Throw in so for several times, throw in the liquid detergent of constant volume chamber cubical content multiple.
Also can change the size in constant volume space,, so just can throw in the liquid detergent of 10CC or its multiple amount such as being set to 10CC.
The state of each valve of whole cleaning solution launch process is following:
