Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has two washing tubs, and the washing liquid and rinse water used in the other washing tub are transferred to one washing tub by the pump action of the back blade of the rotary blade of one washing tub. , which allows used washing liquid and rinsing water to be reused.

Furthermore, when transferring the liquid from the other washing tub to one washing tub, water is prevented from being scattered due to the rotation of the rotary blade of one washing tub.

This will be explained below based on the diagram.

Inside the machine frame 1, there is a washing tub 2 of a non-automatic washing machine that only performs washing and rinsing, and an outer tub 4 (washing tub 4) that contains a washing/drying tub 3 of an automatic washing machine that automatically performs everything from washing to spin-drying. ) are installed in parallel.

The outer tank 4 is suspended from the top of the machine frame 1 by a suspension rod 5 having a vibration-proofing mechanism, and the drive motor 7 for rotating the rotary blade 6 and the dehydration tank 3, a bearing case 8, etc. are attached to the bottom of the outer tank. ing.

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 15 denotes a water supply channel connected to a faucet, which is branched into two 16 and 17. One 16 supplies water to the washing and dewatering tank 3 via a water supply solenoid valve 18, and the other 17 supplies water to a manual water supply valve 19. Water is supplied to the washing tub 2 through the washing tub 2.

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 the boots IJ-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.

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 communication solenoid valve 34.

Next, to explain the electric circuit diagram, 36 is a circuit on the automatic washing machine side, 37 is a water level switch that detects the water level in the outer tub 4 and switches from the normally closed contact 38 to the normally open contact 39 when it reaches the specified water level, 40 1 is a timer motor that drives the program timer, and 41 to 45 are program switches built into the program timer, which are controlled to open and close according to the programming shown in FIG.

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 2, and has an automatic reversing switch 51 in addition to the main switch 50.

52 is a starting capacitor. Reference numerals 29 and 30 designate select switches which are controlled to open and close as shown in the operational diagram of FIG. 5 by operating the reuse switching heir 53 in the operation panel 14 shown in FIG.

The communication solenoid valve 34 and the delay relay 54 are connected to the b contact of the select switch 29.

55 is a normally open contact of a relay that closes about 10 seconds after the delay relay 54 is energized, and the select switch 29
It is inserted between the b contact of the rotary blade drive motor 22 and the rotary blade drive motor 22.

59 is a power source. In Figure 4, 56 is a washing timer 49
, 57 is the drain switching illegitimate child that opens and closes the manual drain valve 27, and 58 is the setting illegitimate child of the program timer.

Next, the operation will be explained.

When the reuse switching heir 53 is turned off, the select switch 29 closes to the a contact and opens the b contact.
The communication solenoid valve 34 is not energized and is closed, and the washing tub 2 and the outer tub 4 are in an independent state, and washing and rinsing are performed in the washing tub 2, while washing and dehydration are performed in the washing/drying tub 3, respectively. They can be performed independently without being related to each other.

That is, the select switch 30 is connected to the rotary blade drive motor 22.
, and the circuit 36 on the automatic washing machine side is energized via the a contact of the select switch 29, respectively.

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 53 to "reuse" at the end of the washing process. do.

Then, the select switch 29 switches from the a contact to the b contact, cutting off the power to the automatic washing machine side circuit 36 and temporarily stopping the operation, and energizing the communication solenoid valve 34 to open it, and the inside of the outer tub 4 is The washing liquid is transferred to the washing tub 2 via the connecting path 35.

At the same time, delay relay 54 is also energized.

When the water level in the washing tub 2 rises to a point where the rotary blades 20 are sufficiently immersed, for example, as shown by the water level line, due to the liquid transfer, the normally open contact 55 of the delay relay 54 closes and the rotary blade drive motor 22 is rotated in one direction regardless of the washing timer 49, and the rotary blade 20 is rotated.

As a result, the outer tank 4 is now pumped by the rotor blade back blade 31.
The liquid inside is transferred to the washing tub 2.

At this time, if the rotor blade 20 is rotated at the same time as the communication solenoid valve 34 opens, there is no liquid on the rotor blade 20 at the beginning of rotation, so the transferred liquid will be violently scattered due to the rotation of the rotor blade 20. There is a risk that it may fly out of the aircraft and wet the floor.

However, according to this washing device, after the communication solenoid valve 34 is opened, the rotary blade 2
0, the liquid transfers to some extent before the rotor 20 rotates, submerging the rotor 20 in the liquid, and even when the rotor rotates, the liquid will scatter violently and wet the floor. Nothing happens.

Then, when the desired amount of washing liquid is transferred to the washing tub 2, if the reuse switching heir 53 is set to "off", the b contact of the select switch 29 is opened, and the delay relay 54 is opened.
The excitation of the communication solenoid valve 34 is cut off and the normally open contact 55 is opened to cut off the power to the rotary vane drive motor 22 and stop the rotary vane 20. At the same time, the communication solenoid valve 34 is also deenergized and closed. 2 and the outer tank 4 are made independent.

Therefore, the used washing liquid transferred to the washing tub 2 can be reused to wash other items.

Also, according to the minute setting of the eldest child 53, power is re-energized to the automatic washing machine side circuit 36 via the a contact of the select switch 29, and the remaining processes are restarted.

In the above explanation, the used washing liquid in the washing and dehydrating tank 3 is transferred to the washing tub 2 and reused. However, the water used for rinsing in the washing and dehydrating tank is transferred to the washing tub and reused. You can do that as well.

In addition, although the valve body interposed in the connecting path 35 is of a solenoid valve type, it is also a manual % type that is operated by the reuse switching heir 53 and opens when the valve is set to "reuse". Although the delay relay 54 is used as a means for delaying, a timer or the like may also be used.

Furthermore, the two washing tubs are a washing tub 2 of a non-automatic washing machine and a washing tub 4 (outer tub) of an automatic washing machine, but the washing tub of any type of washing machine may be used.

Therefore, according to the present invention, it is possible to easily transfer the used washing liquid and rinse water from the other washing tub to one of the two washing tubs by using the pumping action of the back blade of the rotary blade. This allows the used washing liquid and rinse water to be easily reused without having to take out and transfer the laundry in the other washing tub.

Furthermore, it is possible to provide a washing device that exhibits excellent effects such as eliminating the risk of the liquid scattering due to the rotation of the rotor blades and wetting the floor surface when the washing liquid and rinsing water are transferred to one of the washing tubs.
