Abstract

The utility model relates to a device of the automatic water supply and drain combined device for a washing machine, in particular to a combined device to realize the automatic water supply and drain of a washing machine. A water valve which is arranged on the drainage passage is arranged on the water supply passage of the combined device; a cam which is driven by a motor can drive a right angle type pull rod on the water valve of water supply or water drain to move to start the water valve of water supply or water drain; a controller can control the state of water supply, or non-water supply, or non-water drain, or water drain by controlling the positioning rotation of the motor without using an electromagnetic valve.

Description

Automatic water supply and drain combined device for washing machine

The utility model relates to a kind of device of realizing that washing machine advances automatically, draining is controlled, particularly a kind of composite set of realizing that washing machine advances automatically, draining is controlled.

At present, the automatic washing machine of Chu Xianing has a pulling water valve on drainage channel on the market, and its unlatching is inhaled moving device control by electromagnetism, and they have formed drain solenoid valve.Intake tunnel is by the monolithic devices solenoid control.The work of these electromagnetic valves has brought tedious noise.And, because in the whole process of water inlet or draining, corresponding solenoid valve will be worked always, thereby not only make the noise time of sending than growing but also damaging electromagnetic valve easily and expend more electric energy, these electromagnetic valves are also all more expensive.

The purpose of this utility model provides a kind of the need and realizes that with electromagnetic valve washing machine advances automatically, draining control, and lower-cost device.

The utility model is to realize like this, cancel electromagnetism still loading onto the pulling water valve that is equipped with on the present washing machine drainage passage on the drainage channel and inhale moving device, intake tunnel is shifted near drainage channel, and one of repacking similarly spurs water valve and cancels the monolithic devices electromagnetic valve on intake tunnel, the pull bar of these two water valves type of all squaring up, increase the cam of a motor and drive thereof, along with the rotation of motor can make perpendicular type pull bar on cam driven water inlet or the draining water valve move and realizes intaking or the unlatching of draining water valve, increase a controller in addition,, the location of control motor realizes water inlet so that rotating, do not advance the control of not draining or hull-borne, thereby realize advancing automatically of washing machine, draining control.

Like this, just can not adopt electromagnetic valve and realize advancing automatically, draining control, and only in the process of two states conversion this device just work, thereby can reduce noise, energy consumption and fault, can also reduce cost.

Further improvement of the utility model be with advance, drainage channel is communicated to overall channel and constitutes a valve body, can make easy for installation like this.

Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail.

Accompanying drawing 1: the utility model is in the A-A cutaway view of hull-borne.

Accompanying drawing 2: the utility model is in the vertical view of hull-borne.

Accompanying drawing 3: the front view of cam 4.

Accompanying drawing 4: the wiring diagram of the internal wiring of controller 8 and motor 5.

Fig. 1,2 has described that this washing machine advances automatically, drain combined assembly, it has the valve body 1 that intake tunnel X and drainage channel Y is communicated to overall channel T and constitutes, into water water valve 2 and draining water valve 3 are arranged respectively on intake tunnel X and drainage channel Y, cam 4 is driven by motor 5 and clockwise rotates, its chimb can back down the perpendicular

type pull bar

6 or 7 and realize that the unlatching of water inlet water valve 2 or draining water valve 3, controller 8 can control motor 5 and rotate in water inlet, the location of not advancing not draining or drainage position on water water valve 2 into or the draining water valve 3.Microswitch 9,10 in the controller 8 is installed in the below of the advancing of valve body 1, drainage channel X, Y.

Fig. 3 has described cam 4, have on cam planes with centre of gyration O is the projection 11 of 2/3rds disk volumes at center, this projection radius should be greater than the front contact of microswitch 9,10 distance to motor 5 axle center, and is symmetrical in the line of chimb summit and centre of gyration O.

Fig. 4 has described the internal wiring of controller 8 and the circuit connection diagram of motor 5, the normal-closed end of the Chang Kaiduan of the microswitch 9 in the controller 8, normal-closed end, microswitch 10 is lead-out wire G, H, I respectively, the common port of microswitch 9 is connected to the Chang Kaiduan of microswitch 10 by lead, the common port lead-out wire J of microswitch 10 also is connected to an end of motor 5, other end lead-out wire K by lead.Dotted line is meant the connecting line with the washing machine control circuit.

Washing machine provided by the utility model advances automatically, drain combined assembly, its overall channel T is connected on the delivery port under the washing machine drum in use, lead-out wire G, H, I and K are connected to water intaking valve control end L, the draining valve control end M of washing machine control circuit, the Chang Kaiduan M of water level switch and the zero line of power supply respectively.When not working, the chimb of cam 4 backs down draining water valve 3, and projection 11 touches microswitch 9,10 and makes device be in hull-borne, and the water valve 2 of intaking this moment is in closed condition.When needs were intake, the timer on the washing machine was to water intaking valve control end L power supply, and motor 5 gets electric drive cam 4 and rotates 120 °, discharge draining water valve 3 and microswitch 10, and back down into water water valve 2, motor 5 cuts off the power supply and locatees, device is in into water state, and draining this moment water valve 3 is in closed condition.When the water level in the washing machine reaches predetermined height, water level switch is connected, water intaking valve control end L outage, the Chang Kaiduan M of water level switch gets electric and makes motor 5 get 120 ° of electric drive cam 4 rotations, discharges water inlet water valve 2 and microswitch 9, and projection 11 touches microswitches 10, motor 5 cuts off the power supply and locatees, device can be in not hull-borne, and advance this moment, draining water valve 2,3 all is in closed condition, and washing machine is in the washing state.After washing end, the timer on the washing machine is to draining valve control end M power supply, and motor 5 gets electric drive cam 4 and rotates 120 °, backs down draining water valve 3, and projection 11 touches microswitch 9 again, and motor 5 cuts off the power supply and locatees, and device is in hull-borne.After draining finished, the timer on the washing machine went to into water state to motor 5 power supplies again.So just, realized advancing automatically, the control of draining.
