Description
Technical field
The present invention relates to the metering control that automated fluid is thrown in.
Background technology
In the past; The cleansing solution that uses electric washing facilitys such as the electrical washing machine of liquid detergent, electric dish-washing machine is (like washing agent; Softening agent; 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 cleansing solution injected volume automatically.So device that needs cleansing solution to throw in automatically on the washing facility.
Disclosed liquid detergent input mode has the suction pump mode on the market, gear-type pump fashion of extrusion and constant volume measurement mode etc.The Perfected electromagnetic metering valve of the CN2008101204252.7 mode that the inventor proposes, the method for employing constant volume combined valve can realize with the constant volume space being the control mode of unit injected volume, but there is following problem in this mode:
1, outlet conduit is arranged on spool conduit the inside; When draining was moved after one time meter action was accomplished; Can only be discharged to the basal surface position of spool at most, can not be emptied to the position, the end in constant volume chamber, cause that liquid residue is arranged in the constant volume chamber; Even the mixed liquor of water and adjuvant also may be in piston and pipe inner wall set after their dryings.
2, the valve of this structure can not realize that two kinds of adjuvants switch the function of throwing in addition.
3, in the constant volume chamber residual liquid is arranged, during the continuous measurement action, each residual quantity is basic identical; Corresponding remaining space too; The amount basically identical of throwing in, but when the time interval is longer, can cause actual filling space to become big after the residual liquid evaporation; Cause the filling quantitative change big, precision is thrown in influence.
Summary of the invention
The constant volume chamber that the present invention will solve the previously presented Perfected electromagnetic metering valve existence of the inventor can not be emptied completely and the requirement that can not realize that the multiple additives switching is thrown in.The present invention provides a kind of electromagnetic measurement valve for this reason, and this metering valve can measure the liquid detergent of set amount, and dashes the liquid detergent of metering with the tap water of input and to transport to cylindric washer, and can realize that liquid detergent repeatedly measures input.

Below in conjunction with accompanying drawing the present invention is described further.
The principle of work of electromagnetic measurement valve of the present invention:
During meter action:
The user who loads the washing facility (such as washing machine) of this delivery device throws in enough nonexpondable adjuvant in the liquid additive groove, when needing to throw in, chew 108 at gas and connect negative pressure source (like air pump or flow suction pump); Valve ball D9 receives and attracts to move down, and valve D is closed, and opens the respective electrical magnet valve for this moment solenoid 3 energisings; Moveable piston 5 is attracted valve B13 is opened, and valve A12 closes, under the vacuum suction effect; Liquid agent (comprising washing agent, softening agent, germifuge etc.) is chewed 107 through feed liquor and is got into constant volume chamber 109 with valve B13, and along with the increase of liquid agent, liquid level rises; Valve ball C8 rises, and is full of up to the constant volume chamber.The state of this each valve of process is following:
Constant volume chamber valve A: close
Constant volume chamber valve B: open
Constant volume chamber valve C: open
Constant volume chamber valve D: close
Valve ball C8 contacted with valve seat C when the constant volume chamber was full of; Valve C14 closes, and makes constant volume chamber and gas chew 108 blocking-up, the sealing of constant volume chamber; Even after this gas is chewed and is continued to provide attraction power; Because valve C14 closes, it is indoor that the suction at the gas place of chewing can not be delivered to constant volume, and liquid agent can not get into the constant volume chamber again.The state of the next valve of this state is following:
Constant volume chamber valve A: close
Constant volume chamber valve B: open
Constant volume chamber valve C: close
Constant volume chamber valve D: close
Even the negative pressure source of the gas place of chewing connection has pressure surge or liquid agent viscosity difference like this, cause the inflow velocity of liquid agent different, and a meter action is identical to the amount of the liquid agent of the indoor filling of constant volume.
After the constant volume chamber is full of and the wait process finishes,, close constant volume chamber valve B through the said solenoid valve of operation; Open constant volume device valve A; Tap water is chewed 106 inputs from water inlet, through the interstitial hole 401 and the valve A12 inflow constant volume chamber 109 of secured core 4, valve ball C8 rising this moment valve-off C; Valve ball D9 rising Open valve D, the indoor liquid agent of constant volume is mixed the back and is chewed 105 outflows from the water outlet of constant volume device in the lump together with tap water with the tap water of inflow.
Each valve state of this process:
Constant volume chamber valve A: open
Constant volume chamber valve B: close
Constant volume chamber valve C: close
Constant volume chamber valve D: open
Constant volume chamber evacuation procedure:
After dashing defeated the end, water inlet is closed, and the constant volume room pressure is removed; Constant volume device gas is chewed 108 and is in the atmosphere opening state; The indoor liquid of constant volume just under the effect of deadweight, is chewed 105 through the water outlet of constant volume chamber and is discharged, and drops to water outlet up to the indoor liquid height of constant volume and chews the position.Be provided with lowlyer if the position is chewed in water outlet, the indoor liquid of constant volume is discharged totally fully, reach the effect of protection moveable piston.
Each valve state of this process:
Constant volume chamber valve A: open
Constant volume chamber valve B: close
Constant volume chamber valve C: open
Constant volume chamber valve D: open
So once throw in the liquid agent that action can be thrown in constant volume chamber volume (such as 10CC) amount, more if desired, can carry out again 1 time, 2 times ... Throw in so for several times, throw in the liquid agent of constant volume chamber volumetric quantity multiple.
More than explanation is the electromagnetic measurement valve of throwing in a kind of liquid agent.Also can control the interpolation of two kinds of liquid agent respectively, add liquid detergent during such as program for washing, add liquid softener or germifuge during rinsing in the indoor combination that two valve A, two valve B are set of constant volume.
