Electromagnetic valve for jet mixer
Technical field
The jet that the present invention relates to the liquid detergent that a kind of detergent for washing machine is mixed to form even concentration with water mixes
The electromagnetic valve of clutch, belongs to the detergent input technology of washing machine.
Background technology
No matter laundry clothes use machine washing or hand washing, and preferable way is first to make concentration cleaning mixture suitable, uniform,
The medicated clothing will washed again puts into and stirs evenly, and by the immersion of cleaning mixture, uses the tension force of detergent to be separated with medicated clothing by dirt,
Can wash clean medicated clothing.
The clothes washing method correct with washing machine should be: first start discharges water, and it is the most mixed with water that water puts into detergent after putting enough
Close, then put into medicated clothing washing by soaking.
But requiring time for owing to discharging water, medicated clothing, in order to save trouble, is typically directly put into the washing tub of washing machine, with warp by people
Test a certain amount of detergent of input, then start water inlet laundry clothes.Owing to not being that the cleaning mixture carrying out even concentration in advance puts clothing again
Thing soaks, and after causing medicated clothing to be saturated with water, detergent is just difficult to be dissolved between the fiber of medicated clothing and goes, so usually occurring washing not
Enough clean situations, and, part of article contacts the long period due to the detergent with high concentration, showing of decolouring even occurs
As.
Although some has the washing machine of putting detergent function, also it is by the detergent of not diluted during water inlet
Directly throw in into washing tub.In the patent of Application No. 200820034740.7, disclose washing powder of washing machine automatically add dress
Put, advantage be can automatic washing-powder feeding, and overcome the problem of detergent caking blocking, deficiency is directly to be thrown by detergent
Enter washing tub, still can not first make the suitable liquid detergent of concentration.
It is total enclosing during the work of Part Full Automatic washing machine, if to throw in medicated clothing more extremely difficult for cleaning mixture to be carried out.
A kind of detergent for washing machine and disinfectant is disclosed in the patent of Application No. 201010179091.1
Automatic adding device, advantage is to have accomplished relatively accurate control, shortcoming be detergent be water inlet during use stage
Throw in, but still can not accomplish that enter washing tub is all the cleaning mixture of even concentration, and complicated structure.
In the patent document of Patent No. 201110120512.8, disclose a kind of detergent throw in and mixing arrangement,
Dispose the discharging gate of a duckbill in the discharging opening of charging basket, under the effect of feeding engine, detergent is got into turbine stirrer
Mixing with water, advantage is to blend uniform cleaning mixture, and deficiency is that the discharging gate of duckbill uses elasticity meeting after time length
Weakening, cause sealing to reduce, detergent is likely to penetrate into turbine stirrer, causes to precisely input according to inflow and washes
Wash agent.
It is, thus, sought for a kind of equipment that can accurately control detergent input quantity according to inflow.
Summary of the invention
It is an object of the invention to provide a kind of equipment that can accurately control detergent input quantity according to inflow.
The technical scheme is that the electromagnetic valve for jet mixer, jet mixer is mainly by ejector 1, electricity

Axis is provided with through feeding-passage 25, and feeding-passage 25 is taper, one end of feeding-passage 25 and the charging hole on ejector
11 are threaded connection, and the other end communicates with hopper by spigot joint 26;The diameter of described valve ball is at the bottom of less than the cone of feeding-passage
Diameter, more than the vertex of a cone diameter of feeding-passage;Being provided with coil bore at feeding-passage and valve body, coil bore is provided with peace in valve body surface
Dress mouth, described installing port is the annular opening around feeding-passage cone bottom outer wall, and solenoid enters coil from installing port
Chamber is also enclosed within feeding-passage outer wall;Valve ball and spring is filled in from one end at the bottom of the cone of feeding-passage successively feeding-passage, then will connect
Mouth 26 is connected with the cone bottom of feeding-passage, makes spigot joint holddown spring, valve ball is pressed to the vertex of a cone end of feeding-passage, blocking charging
Passage;Described spigot joint 26 are provided with the back-up ring matched with installing port, after the spigot joint cone bottom with feeding-passage is connected,
The clogging installing port of back-up ring, is fixed on solenoid in coil bore.
The cone bottom inwall of described feeding-passage is provided with female thread or draw-in groove, and described spigot joint outer wall is provided with and matches
Female thread or bayonet socket, both or are connected together by screwed together.
It is provided with agitator in described blender, the water flowed into from ejector and detergent is stirred mixing, reinjects and wash
In clothing bucket.
When pressure signal transmission is conversed instantaneous to control system, control system by pressure transducer according to pressure signal
Flow of inlet water, further according to the ratio requirement of cleaning mixture, controls to export the current intensity to solenoid or voltage swing;Electromagnetic wire
Circle produces the magnetic force of varying strength by the current intensity inputted or voltage swing;Magnetic force inhales dynamic valve ball, makes valve ball overcome spring
Elastic force, move to the direction of hopper, between the endoporus of valve ball and feeding-passage produce a space, enable detergent to pass through
Space is inhaled in ejector, and arrives blender together with the water of water inlet end, is mixed into the cleaning mixture of even concentration;Electricity
The magnetic force that magnetic coil produces is the biggest, and the distance that valve ball overcomes the elastic force of spring to move to the feed end of feeding-passage is the biggest, at valve
Space between ball and feeding-passage inwall is the biggest, and the detergent being flow to ejector by space is the most.
Described feeding-passage is cone.
