Specific embodiment
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 2 a kind of utilization water intake valve of washing machine injects the device of washing assisant, described device includes water injection module 7 and washing assisant filling module 4, and washing assisant filling module 4 is connected with water injection module 7.
Water injection module 7 includes main water flow pipes 2 and Venturi tube 3, and Venturi tube 3 is in parallel with main water flow pipes 2.
Washing assisant filling module 4 includes washing assisant box 41, metering device 42 and stopper 43, specifically, washing assisant box 41 connects metering device 42, and one end of stopper 43 is connected with metering device 42, and the other end is connected with the injection port at the throat 33 of Venturi tube 3.
Washing assisant filling module 4 is provided with communicator, and washing machine is provided with control washing assisant filling module(4)Control module, described control module connects the program control system of washing machine, and described communicator can be realized communicating with the control module of washing machine.
During use, it is connected running water outlet mouth 1 after the port of the inlet cylinders section 31 of Venturi tube 3 is merged with one end of main water flow pipes 2, the port of diffuser 34 of Venturi tube 3 is connected water intake valve of washing machine 5 after merging with the other end of main water flow pipes 2, start washing machine, washing machine controls washing assisant filling module(4)Control module and washing assisant fill module 4 and be provided with communicator and realize communicating.
The tap water of running water outlet mouth 1 injection flows through main water flow pipes 2 and Venturi tube 3 simultaneously, enter water intake valve of washing machine 5 afterwards and open it, the program control system of washing machine simultaneously or postpones to send instruction, open stopper 43, when tap water passes through the throat 33 of Venturi tube 3, negative pressure is produced near throat 33, now throat 33 nearby produces adsorption, washing assisant is inhaled into the throat 33 of Venturi tube 3, the port of washing assisant circular cone diffuser 34 from Venturi tube 3 with tap water is flowed out, then the tap water flowing out with main water flow pipes 2 converges, together washing machine is injected by water intake valve of washing machine 5.
After reaching washing assisant specified consumption, metering device 42 feeds back to washing machine procedure control system, the program control system of washing machine sends instruction again, close stopper 43, stop washing assisant filling, now, still through Venturi tube 3, the washing assisant that tube wall is rinsed and guarantees with suction is well into washing machine for tap water.
Now, because stopper 43 is closed, tap water can't enter washing assisant filling module 4 it is therefore prevented that tap water pours in down a chimney, and dilute, pollute washing assisant.
After adding water to washing machine and specifying water level, water intake valve of washing machine 5 is automatically switched off, and washing machine is started working.
Liquid washing assisant minimum level in washing assisant box 41 is higher than the water inlet of the injection port at the throat 33 of Venturi tube 3 and/or water intake valve of washing machine 5.
When tap water separately flows into main water flow pipes 2 and Venturi tube 3, the assignment of traffic of two pipelines must is fulfilled for following condition:After water flowing before washing assisant flows into clothing machine water intaking valve 5, water intake valve of washing machine 5 must first be opened by tap water;In addition, when current pass through Venturi tube 3, the throat 33 of Venturi tube 3 can produce enough negative pressure, washing assisant is sucked the throat 33 of Venturi tube 3, and in water tub of washing machine(6)Water level reach specified water level before, suck specify consumption washing assisant.
The operation principle of Venturi tube 3 is as follows:
As shown in figure 3, standard(Classical)Venturi tube is made up of inlet cylinders section 31, circular cone contraction section 32, cylindrical throat 33, circular cone diffuser 34;A diameter of D of cylindrical section 31, its length is also equal to D;Contraction section 32 is cone, and has 21o±1oAngle;Throat 33 is the circular cylinder section of a diameter of d, and its length is also equal to d;Diffuser 34 is cone, and angle of flare is 7o~15o
When current flow inside Venturi tube, at the narrowest place of pipeline(I.e. cylindrical throat 33), dynamic pressure(Velocity head)Reach maximum, static pressure(Resting Pressure)Reach minima, the speed of current rises because of the relation that diminishes of the cross-sectional area that shoves, and entirely shoves and will experience pipe reductions process within the same time, thus pressure is also in the reduction of same time, and then generation pressure differential, this pressure differential is to fluid one external suction of offer.
Water intake valve of washing machine 5 is guide electromagnetic valve, and its structure and operation principle are as follows:
As shown in figure 4, its structure of water intake valve of washing machine 5 mainly includes:Electromagnetic valve has been divided into intake antrum 552, control chamber 551 and water chamber 553 by valve body 50, valve element 51, electromagnet coil 52, spring 53 and iron core 54, valve body 50 and valve element 51;
Valve body 50 is provided with water outlet port 56, water inlet port 57 and apopore 58, and apopore 58 is arranged on the inside of electromagnetic valve 5, and valve element 51 is above apopore 58, and valve element 51 is when deforming upon, and apopore 58 is sealed by valve element 51 just;
Valve element 51 is provided with pressurization hole 511 and centre bore 512;
As shown in Figure 4, water intake valve of washing machine is closed type, in the state of no power not water filling, iron core 54 is pressed to the centre bore 512 of valve element 51 by the effect of spring 53 elastic force, and centre bore 512 is sealed, simultaneously in the presence of elastic force, valve element 51 is pressed on apopore 58, also apopore 58 is sealed, now centre bore 512 and apopore 58 are in closed state;
When tap water injects from the port 57 that intakes, current are gradually filled with intake antrum 552 in the direction of the arrow, subsequently enter control chamber 551 from pressurization hole 511, because centre bore 512 is in closed state, the water of control chamber 551 can't flow out from centre bore 512, it is full of water in intake antrum 552 and control chamber 551, the hydraulic pressure in two chambeies is equal, now under the pressure of water and the collective effect of his spring 53, the active force that valve element 51 contacts side with control chamber 551 contacts the active force of side more than valve element 51 with intake antrum 552, apopore 58 is sealed by valve element 51, centre bore 512 and apopore 58 are in closed state;
After starting washing machine, the electromagnet coil 52 of water intake valve of washing machine 5 is energized, iron core 54 can be in the presence of electromagnetic force, the elastic force overcoming spring 53 moves, now centre bore 512 is no longer sealed, water in control chamber 551 directly flows into water chamber 553 from centre bore 512, because pressurization hole 511 is less, the water intake velocity of control chamber 551 is slower, pressure in control chamber 551 is just less than the pressure in intake antrum 552 quickly, therefore valve element 51 contacts the pressure of side less than the pressure contacting side with intake antrum 552 with control chamber 551, now valve element 51 effect of being stressed is in opening, water directly enters water chamber 553 by apopore 58 from intake antrum 552, as shown in Figure 5.
