Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fully automatic washing machine, and more particularly to a control device for a fully automatic washing machine that performs dewatering and rinsing while intermittently pouring water during an intermediate dewatering process.

Conventionally, this type of apparatus has had the disadvantage that the rinsing effect is reduced due to the generation of bubbles since the water containing the detergent is stirred.

An object of the present invention is to eliminate the above-mentioned drawbacks.

The gist of the present invention is to provide an outer tank attached to the outer frame via a buffer device, a washing and dehydrating tank housed inside the outer tank, and a top cover provided on the top of the outer frame. The fully automatic washing control device, which is equipped with a water supply valve and a shower water inlet connected to the water supply valve, automatically performs a series of washing processes including intermediate dehydration immediately after washing is completed, a selection switch that is turned on only when the button is pressed during the middle of dehydration, excluding the beginning and end of intermediate dehydration, and connected in series with the water supply valve; and a selection switch that is connected in series with the selection switch when this selection switch is turned on. The point is that an intermittent switch is provided.

According to the present invention, bubble generation can be efficiently Hereinafter, the present invention will be explained based on the drawings of an embodiment.

As shown in FIG. 1, an outer tank 2 is attached to an outer frame 1 via a buffer device 9.

Inside the outer tub 2, a washing/dehydrating tank 3 is housed, which is a washing tub for washing and a dehydrating tank for dehydrating, and a pulsator 4 is disposed at the center of the bottom of this washing/dehydrating tub 3.

A drain valve 5 is attached to the bottom of the outer tank 2, and a drain hose 6 is connected to the drain valve 5.

A clutch 7 is provided at the center of the bottom of the outer tub 2, and the clutch 7 transmits the power from the motor 8 to the pulsator 4 during washing and to the washing/drying tub 3 during dehydration.

A top cover 10 is provided on the top of the outer frame 1.

A panel 12 is attached to this top cover 10,
Furthermore, this panel 12 has a timer 11 and a liquid level switch 1.
3 is provided.

The liquid level switch 13 detects the amount of water supplied, and when a predetermined amount of water is reached, the water supply electromagnetic pulp 15 provided inside the panel 12 is turned off to stop the water supply.

A water inlet 14 for injecting water into the washing and dewatering tank 3 is connected to this water supply valve.

This water inlet 14 is provided in the top cover 10.

Further, a water supply hose 16 is connected to the water supply valve 15 .

The shape of the water inlet 14 has a hole diameter of approximately 1 meter and a pitch of 5 meters.
Approximately 100 of them were provided at intervals of .

The water injected from the water inlet 14 flows out from the individual outflow holes in an almost linear shape at a relatively slow outflow speed, and the cross section of the entire flow horizontally cut in the streamline direction is a dot. It flows out in the form of a layered shower.

Note that this water inlet 14 is connected to the pulsator 4 with a slow circumferential speed.
It is arranged so that water is poured into the top like a shower.

Next, the control circuit of the fully automatic washing machine having the above-mentioned configuration will be explained with reference to FIG.

A pilot lamp 29, a solenoid 30, a water supply valve 15, a timer motor 28 button, and a triangle button of the motor 8 are commonly attached to one end of the power source 17.

In addition, the cam switch 18゜1 connected to the other end of the power supply 17
9.20.21.22.23 Buttons 24 are switches for executing a predetermined cycle according to the cycle table of the program chart shown in FIG.

The reversing switch 25 switches the motor 80 for a certain period of time.
This is a switch that changes the direction of rotation, and the switch 26 is an intermittent switch that is turned on and off at a certain period of time.

The lid switch 27 is a switch that senses abnormal vibrations during dehydration and turns off the power to the circuit.

The timer motor 28 is a motor that operates each cam switch, and the pilot lamp 29 is an operation display lamp.
The solenoid 30 opens and closes the drain valve 5.

Here, the intermittent switch 26 is intermittently turned on during intermediate dehydration.
The cam switch 21 operates independently of the intermittent switch 26 during rinsing, and is a selection switch that controls the water supply valve 15 by the intermittent switch 26 during intermediate dehydration.

As is clear from the program chart in FIG. 3, the b side of the sludge cam switch 21 is designed to close after a while after the start of dewatering before rinsing, that is, during intermediate dehydration, and open before the end. .

Next, the operation of the above configuration will be explained.

1) When cam switch 1B is turned on, cam switch 1
9.24 is closed, the cam switch 22 is closed to the a side, and the liquid level switch 13 is closed to the NC side, so the water supply valve 15 is energized and water supply starts.

After a predetermined amount of water has been supplied, the liquid level switch 13 switches to the No side to stop water supply, and then the cam switch 23 switches to a
When the washing machine is closed to the side, the cam switch 24, the reversing switch 25, and the motor 8 are energized to perform washing.

After a certain period of time has elapsed, the cam switch 20 closes, the cam switch 22 closes to side b, and the cam switch 23 closes.
．． 24 each open to start draining water.

Then, after a certain period of time has passed, the cam switch 19
opens, the liquid level switch 13 switches to the NC side, and the cam switch 23 closes to the b side, starting intermediate dehydration.

After a while, when the cam switch 21 is closed to side b, the water supply valve 15 is energized, and water is supplied while dehydrating.

At this time, since the circuit to the water supply valve 15 passes through the intermittent switch 26, water is injected from the water supply valve 15 intermittently.

For example, water is supplied for 3 seconds and water supply is stopped for 7 seconds, 12 times for 2 minutes.

At this time, water is intermittently poured onto the pulsator 4 in the form of a shower from the numerous outflow holes of the water inlet 14 to perform dewatering.

Since closing the b side of the broken cam switch 21 is made slower than closing the b side of the cam switch 23, the generation of bubbles can be suppressed.

In other words, the laundry immediately after washing contains a lot of detergent, but since clean water is poured after the laundry is dehydrated to remove the detergent contained in the laundry, a large amount of foam will not be generated. do not have.

Even if a small amount of foam occurs, a shower-like water injection will effectively eliminate the foam.

Before the spin-drying is finished, the cam switch 21 is turned off and the intermittent water supply is stopped, so that only the effect of centrifuging the water that is soaked in the laundry is produced, so that when the spin-drying is finished, The laundry can be dehydrated at a high rate.

Furthermore, in the unlikely event that water drips between the outer tub and the washing/spin-drying tank even though the drain valve is open due to intermittent water supply, the intermittent water supply will stop before the spin-drying is finished. Only the stop and dehydration action works, so when dehydration is complete! Now, the water that has accumulated between the outer tank and the washing/drying tank can be quickly drained.

After dehydration for a predetermined time, the cam switch 19.24 closes,
When the cam switches 21, 22, and 23 are switched to the a side, and the cam switch 20 is opened, rinsing is started.

At this time, since the cam switch 21 is closed to the a side, even if the liquid level switch 13 is switched to the NO side, the water supply valve 1
5 is energized, and the state of water injection rinsing can be maintained.

Next [The washing cycle ends after draining and spin-drying according to the time cycle, but since the cam switch 21 is open during the last spin, the water supply valve 15 is not energized and water is not supplied during spin-drying, resulting in a poor spin-drying rate. No worries.

In this way, according to the above embodiment, an intermittent switch 26 is provided to open and close the water supply valve 15 intermittently during intermediate dehydration, and the water is periodically passed through the water inlet 14 to the washing/dehydration tank 3.
By injecting water intermittently in the form of a shower, the splashing of water and the sound of water stirring can be suppressed to the extent that it is not a practical problem, and the amount of water supplied can be reduced by approximately 101 J, resulting in a significant water saving effect. was gotten.

As described above, according to the present invention, a control device for a fully automatic washing machine that can efficiently control foaming and improve the rinsing effect is provided.
