Embodiment
Technical scheme is further illustrated below by embodiment.
Fig. 1, Fig. 2 are to carry Electrocontrolled tee valve washing machine complete machine structure schematic diagram described in embodiment one.As shown in the figure, general
On the basis of logical washing machine, an Electrocontrolled tee valve 2, the discharge outlet 21 and drainpipe of Electrocontrolled tee valve 2 are set behind draining pump 3
4 are connected, for the waste water after washing to be discharged；The circulation port 22 of Electrocontrolled tee valve 2 is connected with inner circulating tube 5, interior circulation
Pipe 5 is in washing machine shell 1, and the gap along between washing machine shell 1 and outer barrel, finally enters in washing of drum type washing machine cylinder.
Fig. 3 to Fig. 8 gives the structure composition schematic diagram of Electrocontrolled tee valve 2 in the first embodiment.Electrocontrolled tee valve 2 wraps
Cavity volume 25 is included, the cavity volume 25 is the trigone being made of three square side walls, a triangle roof and a triangle bottom wall
Columnar hollow structure.Water inlet 23, discharge outlet 21 and circulation port 22 are respectively equipped with three of them side wall.The discharge outlet 21 and follow
The angle of two walls where collar extension 22 is provided with rotation axis 27, and one end of rotation axis 27 is inserted into 25 roof of cavity volume, and the other end is inserted
Enter in 25 bottom wall of cavity volume, and be connected by shaft coupling with 24 output shaft of electric machine assembly, electric machine assembly 24 passes through output shaft
Rotate and drive rotation axis 27 to rotate, rotation axis 27 is driven with this.Rocker 26 is connected with rotation axis 27, and rocker 26 is with turning
Moving axis 261 is one of the forming, and such a connection mode is relatively more firm.When electric machine assembly 24 drives the rotation of rotation axis 27 so that rocker
26 are swung left and right, and water inlet 23 is communicated with discharge outlet 21 or 22 one of both of circulation port.
In this present embodiment, the angle of two walls where discharge outlet 21 and circulation port 22 is less than 90 degree, this angular dimension can be with
So that the rocking tendency of rocker 26 is smaller, reduces and wave the time, reduce control difficulty, add flexibility, easily control
System.Certainly, the angle can also be greater than or equal to 90 degree.
In this present embodiment, rocker 26 and rotation axis 27 can also be two separate pieces, and one is connected to by attachment device
Rise, but not as integrally formed part consolidates.
Rocker 26 includes connection floor 261, and one end of connection floor 261 is fixedly connected in rotation axis 27, and the other end connects
It is connected to the water fender 262 for blocking discharge outlet 21 or circulation port 22.Wherein connect floor 261 and water fender 262 is integrated
Shaping, this kind of structure are relatively more firm.Wherein water fender 262 includes plate chamber 263 and the plate being detachably arranged in inside plate chamber 263
Core 264, is provided with centre bore 265 in the plate core 264, can easily replace plate core when plate core 264 is damaged, add material
Expect utilization rate.Centre bore 265 is provided with cricoid groove in plate core 264.The thickness of plate core can be reduced, mitigate weight
Amount, saves material, reduces cost.
In this present embodiment, it can also be two separate pieces to connect floor 261 and water fender 262, connected by fixing device
Together, this kind of connection mode can eaily combine replacement connection floor 261 or water fender 262.
In this present embodiment, water fender 262 may not be is composed of plate chamber 263 and plate core 264, and is integrated into
Type part.But the rocker 26 of such a structure is inconvenient to replace component.

The detergent of laundry powder particles or high concentration between Electrocontrolled tee valve 2 is sprayed by nozzle 6 on the clothing in cylindric washer,
It so can thoroughly dissolve washing powder or detergent and improve the washing effect of clothing well.
Fig. 9 is the complete machine structure schematic diagram that Electrocontrolled tee valve washing machine is carried described in embodiment two.Its with embodiment one not
It is that the mounting means of Electrocontrolled tee valve 2 is different with part：The water inlet 23 of the Electrocontrolled tee valve 2 and laundry machine barrel bottom draining
Mouth 7 connects；The circulation port 22 of Electrocontrolled tee valve 2 is connected by draining pump 3 through inner circulating tube 5 with washing of drum type washing machine cylinder；The electricity
The discharge outlet 21 for controlling triple valve 2 connects drainpipe 4.
In above-mentioned washing machine, the operation principle of Electrocontrolled tee valve 2 is：After electrical power, the left and right of motor output shaft
Rotate and drive 27 left-right rotation of rotation axis, and then control rocker 26 to swing to the left or to the right, discharge outlet can be closed to the right by swinging
21, water inlet 23 is communicated with circulation port 22, water is flowed out from circulation port 22, under the action of draining pump 3, washing in washing machine
Wash water by inner circulating tube 5 iterative cycles in washing tube.Circulation port 22 can be closed by turning left, and make water inlet 23 and draining
Mouth 21 communicates, and the washings in washing machine are directly drained by discharge outlet 21.As draining pump 3 does not start, then maintain neither to spray,
Also the washing state of not draining.
Specifically, in washing process, washings are intake after certain water level, always on or intermittent unlatching draining pump
3, and start Electrocontrolled tee valve 2, by the rotation of electric machine assembly 24, control rocker 26 is swung to the right, closes discharge outlet 21, make into
The mouth of a river 23 is communicated with circulation port 22, water is flowed out from circulation port 22, and under the action of draining pump 3, the washings in washing machine lead to
The iterative cycles in washing tube of inner circulating tube 5 are crossed, washing powder or detergent can be prevented to be deposited in drainpipe 7, and circulating
During fully dissolve, be fully used, while the washings of high concentration are sprayed into cylindric washer by the nozzle 6 of the circulatory system
On clothing, the wash degree of clothing is farthest improved.As draining pump 3 does not start, then maintain neither to spray, also not draining is washed
Wash state.
Drainage procedure is reached after washing process, starts Electrocontrolled tee valve 2, passes through the rotation of electric machine assembly 24, control
Rocker 26 is swung to the left, is closed circulation port 22, water inlet 23 is communicated with discharge outlet 21, the washings in washing machine pass through draining
Mouth 21 is directly drained.
Above-mentioned two embodiment difference is, during washing machine drainage in embodiment one, draining pump 3 can work,
It can also close；During washing machine drainage in embodiment 2, draining pump 3 is closed at this time.
, can be the same with washing process for rinse cycle, Electrocontrolled tee valve can be opened to discharge outlet 21, with normal
Rinsing program.
Technical solutions according to the invention can be applied to roller washing machine or rotary drum washing machine, can be by Electrocontrolled tee valve
The control system of washing machine is connected to by circuit, coordinates corresponding programme-control, the automation acted with realization.
Above in association with the specific embodiment technical principle that the invention has been described.These descriptions are intended merely to explain the present invention's
Principle, and limiting the scope of the invention cannot be construed in any way.Based on explanation herein, the technology of this area
Personnel would not require any inventive effort the other embodiments that can associate the present invention, these modes are fallen within
Within protection scope of the present invention.
