Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a washing machine having two washing tubs, in which washing liquid and rinsing water from the other washing tub can be easily transferred to one washing tub. The purpose is to provide a washing device that can be reused.

Conventionally, when there is a large amount of laundry, only the rated capacity of the washing machine is washed first, and once the laundry is finished, the laundry is placed in another container (
For example, the laundry was left in a bucket (for example, a bucket), and the remaining laundry was washed without draining the washing liquid from the washing tub, and the washing liquid was reused.

After washing the remaining laundry, the washing liquid is drained and the laundry left in the container is rinsed, which takes a lot of time and is cumbersome to complete. Ta.

If you use two washing machines, you can wash your clothes in one washing machine and then transfer the laundry to the adjacent washing machine for rinsing.

In the meantime, another item of laundry can be washed using the first washing liquid, and then rinsed in the adjacent washing machine.
The overall time required for washing is reduced.

From this point of view, washing machines with a structure in which washing tubs are installed side by side have been proposed, but even with such washing machines, in order to reuse the washing liquid, the laundry must be transferred by hand, which is a cumbersome process. It required

The present invention has been made in view of these points, and will be explained below based on the drawings.

Inside the machine frame 1, a washing tub 2 and an outer tub 4 (washing tub) containing a washing/dehydrating tub 3 are arranged side by side.

The outer tank 4 is attached to the upper part of the machine frame 1 by a hanging rod 5 having a vibration isolation mechanism.
The rotating blade 6 and a drive motor 7 for rotating the dehydration tank 3, a bearing case 8, and the like are mounted on the bottom of the outer tank.

9 is a belt connecting pulleys 10 and 11.

Reference numeral 12 denotes a drainage channel of the outer tank, which communicates with the outside of the machine via a drainage solenoid valve 13.

Reference numeral 14 denotes an overflow channel of the outer tank, which is connected to the drainage channel 12.

Reference numeral 15 denotes a water supply channel connected to a water faucet, which is branched into two channels 16 and 1γ; one 16 supplies water to the washing and dewatering tank 3 via a water supply electromagnetic valve 18, and the other 1γ supplies water to a manual water supply valve 19. Water is supplied to the washing tub 2 through the washing tub 2.

A series of processes such as washing, rinsing, and dehydration are automatically performed in the washing/dehydration tank 3 based on a program timer.

A rotary blade 20 is provided at the bottom of the washing tub 2.

This rotary blade 20 is rotated by a rotary blade drive motor 22 attached to a base 21.

23 is a belt connecting pulleys 24 and 25.

Reference numeral 26 denotes a drain channel of the washing tub 2, which is connected to the drain channel 12 via a manual drain valve 27.

28 is an overflow channel, which is also connected to the drainage channel 12.

The upper end of the washing tub 2 is extended to form a top plate 30 having a clothes input port 29 into the dehydration tub 3.

In the washing tub 2, only washing and rinsing are performed.

A back blade 31 is formed on the back side of the rotary blade 20, and a pump chamber 33 is formed with the blade 32.

The suction side of the pump chamber 33 and the bottom of the outer tank 4 are communicated through a connecting passage 35 having a valve body 34.

Next, to explain the electric circuit diagram, 36 is a circuit on the automatic washing machine side that automatically performs a series of processes such as washing, rinsing, and spin-drying in the washing/drying tank 3, and 37 is a circuit that detects the water level in the outer tub 4. The water level switch switches from the normally closed contact 38 to the normally open contact 39 when the specified water level is reached, 40 is a timer motor that drives the program timer, 41 to 45 are program switches built into the program timer, and the program is programmed according to the programming shown in Figure 3. Opening/closing controlled.

46 is also an automatic reversing switch built into the program timer and switched over in a relatively short period, 47 is a starting capacitor for the drive motor 7, and 48 is a top cover safety switch that opens when the top cover (not shown) is opened.

A washing timer 49 controls the rotary blade drive motor 22 of the washing tub 20, and has an automatic reversing switch 51 in addition to the main switch 50.

52 is a starting capacitor.

Reference numeral 53 denotes a manual switch controlled by the operation of the reuse switching heir 54 shown in FIG. 4. When the heir 54 is in the "off" position, the NC contacts 55 and 56 are closed; NC contacts 55 and 56 are opened and NO contact 57 is closed.

61 is a power source.

Further, in conjunction with the reuse switching heir 54, the valve body 34 of the connecting passage 35 is opened when "reuse" is set.

FIG. 4 shows the operation panel 66, and 58 is the washing timer 4.
9 is the setting heir, 59 is the drain switching heir that opens and closes the manual drain valve 27, and 60 is the setting heir of the program timer.

Next, the operation will be explained.

When washing or rinsing is performed in the washing tub 2, if the reuse switching heir 54 is set to ``1 off'' and the washing timer 49 is set,
The drive motor 22 is driven via the NC contacts 55, 56 of the manual switch 53 and the washing timer 49 to perform washing and rinsing.

In addition, when performing everything from washing to dehydration in the washing/dehydration tank 3, if you also turn the reuse switching heir 54 to "off" and set the program timer heir 60 to the washing process, the process from washing to dehydration will be performed automatically according to the programming shown in Figure 3. It is carried out in a regular manner.

Next, when you want to reuse the used laundry liquid in the washing and dehydrating tank 3 to wash another laundry, set the reuse switching heir 54 to "reuse" at the end of the washing process. Set.

Then, the valve body 34 opens, and at the same time the manual switch 53 opens.
Since the ONC contact 55 is opened and the NO contact 57 is opened, power is cut off to the automatic washing machine side circuit 36 to temporarily stop the operation, and the rotary blade drive motor 22 is continuously energized to rotate the rotary blade 20 once. Rotate continuously in the direction.

The pump action of the back blade 31 causes the washing liquid in the outer tub 4 to be transferred to the washing tub 2 through the connecting path 35.

After the desired amount of washing liquid has been transferred to the washing tub 2, if the reuse switching heir 54 is set to "off", the NO
Contact point 57 opens to stop rotor blade 20, and
Since the valve body 34 closes and makes the washing tub 2 and the outer tub 4 independent,
By setting the washing timer 49, the washing liquid transferred in the washing tub 2 can be used to wash another item of laundry.

Further, since the NC contact 55 is closed by the "off" setting of the eldest child 54, the power supply to the automatic washing machine side circuit 36 is restarted, and the remaining steps are automatically carried out.

When the reuse switching heir 54 is set to “reuse”, the NC
Since the contact point 55 is opened, the automatic washing machine will not operate even if the program timer is operated by mistake.In other words, the rotary blade 6 will not rotate even when the water level is low and damage the laundry. Since the NC contact 56 is also opened, even if the washing timer 49 is set by mistake, the rotary blade 20 will not be stopped by the reversing switch 51.

In the above explanation, we have described the case where the used washing liquid in the washing/spinner tank 3 is transferred to the washing tub 2 side for reuse. Reuse can be similarly achieved by setting the reuse switching heir 54 to 1 reuse.

FIG. 5 is an electric circuit diagram of another embodiment, in which the valve body 34 of the connection path is a solenoid valve operated by a solenoid 62, and a manual switch 63,
64 and 65 are opened and closed according to the operation diagram in FIG.

37' is a water level switch for the outer tank 4;
It is similar to

The programming is the same as in FIG.

Therefore, when the setting is "1 reuse", the drive motor 22 is energized through the switch 64 and the normally open contact 39' of the water level switch 37' to rotate the rotor blade 20 in one direction, and the solenoid 62 is also turned on via the switch 65. Excite the valve body 3
4 opens the valve.

When the water in the outer tub 4 moves to the washing tub 2 and the water level drops and the water level switch 37' returns to the normally closed contact 38', the rotor 20 is automatically stopped and the valve body 34 is closed to stop the water transfer. It is something that stops.

In the above embodiment, the valve body 34 is opened and closed in conjunction with the reuse switching heir 54 (manual switches 53 and 63 to 65), but the valve element may be operated by another heir.

Further, although the washing tub 2 and the washing tub (outer tub 4) of the automatic washing machine are arranged side by side, the same washing tub 2 may be arranged side by side.

In this case, water can be easily transferred from either side.

Furthermore, when the "reuse" setting was set, the drive motor 22 was driven at the same time as the valve body 34 was opened, but after the valve body 34 was opened and some water had moved, the drive motor 22 was driven and the rotor blade was By rotating the washing tub 20, water can be prevented from scattering in the washing tub 2.

Therefore, according to the configuration of the present invention, one of the two washing tubs is pumped into the other washing tub by using the pumping action of the pump chamber composed of the back blade of the rotor blade and the blade pressure. Used washing liquid and rinsing water can be easily transferred, and the washing liquid and rinsing water can be easily reused without taking out and transferring the laundry.

When transferring washing liquid or rinse water, only the rotor blades of one washing tub rotate continuously in one direction, so even if you accidentally set the timer for the other washing tub, the rotor blades of this washing tub will Even when the water level is low, it won't rotate and damage the laundry.

In addition, it is possible to provide a washing device which exhibits extremely excellent effects, such as being inexpensive and requiring no separate pump when transferring water.
