Abstract

The utility model relates to an automatically controlled washing machine which can make the rinsing of an ordinary washing machine automotive by utilizing a siphon valve, a floating ball or a water pressure device. Two basic forms are provided. The first basic form is that a water pre-entering water tank is arranged on the upper direction of a washing cylinder. The drain valve of the washing cylinder is opened by the floating ball when the clear water in the water pre-entering water tank reaches a certain water level. The siphon valve is opened to let the clear water enter the washing cylinder when the water level of the water pre-entering water tank reaches the vertex. The second form is that the siphon valve, the floating ball or a water inlet valve controlled by the water pressure device are arranged in the communicating vessel of the washing cylinder. An automatically controlled water inlet valve is closed, and the water flow enters the communicating vessel slowly through another manual valve when the water level raises to a certain height. The siphon valve can be automatically opened to discharge the water when the water level reaches the peak. The washing period of the two form depends on the speed of the water level raising.

Description

Automatic level controlling washing machine

The utility model is the design about semi-automatic washing machine.

The automatic washing machine of making of micro computer and electromagnetic valve can make laundry increasingly automated, but its circuit and complex structure cost an arm and a leg.Conventional laundry apparatus is because each water inlet, draining and motor switch all want manually-operated, particularly rinse cycle to spend most manually, so saying of " laborsaving do not save time " arranged.

The purpose of this utility model be with straightforward procedure make a kind of rinse cycle automation washing machine it should have characteristics simple and reliable for structure, cheap, that be easy to popularize.

Main points of the present utility model are:

1, can utilize the siphon valve of automatic water level control as draining or inlet valve;

2, can utilize ball float or hydraulic devices to realize the automatic control of draining or inlet valve and motor switch;

3, the length of laundry cycles is to regulate by the speed that water level raises, and this speed can artificially be selected;

4, can be with a pre-water tank inlet to save flooding time or to be convenient to realize automatic control.

Accompanying drawing 1 is an embodiment of the present utility model.As shown in the figure, above a common two-tub washing machine, add a pre-water tank inlet 6, siphon valve 4 and ball float 5 are housed in it, ball float is by connecting rod 7 control motor switch 9 and draining valves 10, connecting rod can be drawn below water tank, but to use sealing ring 8 leakproofs, also can after tank top is drawn by a wicket, walk around below the arrival of the water tank outside.Water filling and start laundry in wash bucket 2 earlier during use, anhydrous in the water tank 6 at this moment, ball float 5 is in position A, and motor switch 9 is connected.Allow water purification intake by selected flow velocity then from water inlet 3.Switch 9 cuts out when ball float 5 reaches position B, the motor stall; Meanwhile draining valve 10 is also opened by the ball float active force, and sewage is discharged by side discharge chamber 1 and bottom discharge hole in wash bucket 2, till having arranged.Afterwards, when surpassing the top when further rising of water level in the water tank 6 (this moment, ball float reached position C), the rate of climb is increased sharply because the water surface dwindles suddenly, until flooding the siphon pipe top, siphon valve 4 is promptly opened, so the water purification in the water tank 6 just enters rapidly in the wash bucket 2.Ball float 5 is got back to position A once again, and motor is connected, and begins next rinse cycle again.

The speed of the current that enter from water inlet 3 has determined the length of a rinse cycle.Design should guarantee that the water discharge time of wash bucket 2 is shorter than the shortest time of ball float from position B to C.

The rotating function of conventional laundry apparatus and timing function keep, but timing range will extend to and finishes whole rinse cycle.Regularly finish the appropriate to the occasion alarm signal that is provided with to remind the operator and go to turn off the tap and to do last dehydration.

Accompanying drawing 3 is another embodiment of the present utility model.This is one and conventional laundry apparatus, and as overlapping drums washing machine matched self-control device 15, it and wash bucket 11 are communicated with, and water intaking valve (calling " control valve " in the following text) 16 and one siphon drain valve 19 of hydraulic pressure control is housed in it.The major part of the current that enter from water inlet 17 enters linker through control valve 16.Control valve 16 is standard-sized sheets when beginning to intake.Control valve begins to close when water level reaches A, shuts fully up to B; The motor switch 3 of meanwhile doing washing is also connected by the hydraulic pressure effect, begins laundry.Afterwards, the water inlet current can only slowly enter linker by another hand control valve 18, the length of its flow velocity decision laundry cycles.The siphon valve is opened automatically when water level rises to C, and the sewage in the wash bucket is drained.When water level was lower than a certain height, the control contact 14 of clutch 20 was connected and is made the dehydration tube rotation, to quicken emptying sewage.12 is siphon pipe.

Claims

1, a kind of current automatic control washing machine, it comprises water intaking valve, draining valve, motor, it is characterized in that draining valve or water intaking valve are the siphon valves of automatic water level control; Washing machine has the ball float or the hydraulic devices of the automatic control that realizes draining or inlet valve and motor.

2, washing machine according to claim 1 is characterized in that having a pre-inlet water tank.
