A dewatering tank 5 elastically supported by the washing machine main body 1 is installed in the lower part of the cover plate 2, and a washing tub 6 which is rotatable and also serves as a dehydrating tank is provided inside the dehydrating tank 5.

A pulsator 7 is rotatably provided at the bottom of the washing tub 6 and is driven by a motor 8.

Reference numeral 9 denotes a bearing housing, and the inlet side of the electromagnetic drain valve 10 that is interlocked with a clutch (not shown) installed inside the bearing housing 9 is
It communicates with the bottom of the dewatering tank 5, and a drain hose 12 and an overflow hose 1 are connected to the outlet side of the electromagnetic drain valve 10 via a trifurcated pipe 11.
3 is connected.

The overflow hose 13 connects to the overflow port 14 of the dewatering tank 5 and the cover plate 2.
It branches and communicates with a water storage overflow port 16 of a water storage tank 15 provided at the top and a drain port 36 of a heat exchanger 33, which will be described later.

A water storage drain port 17 is provided at the bottom of the water tank 15, and a cock 18 is provided.
Water is supplied to the dewatering tank 5 through the dehydration tank 5.

A pump 19 has a water suction side connected to the bottom of the dewatering tank 5, and a discharge side connected to a discharge port 21 provided in the water storage tank 15 via a discharge hose 20.

If there is no water in the water storage tank 15, the rinsing liquid is poured into the water storage tank 15 after the final rinsing process.
A water level control device (not shown) is provided to operate a pump 19 to pump water into the water.

22 is a main body of the dryer, which is fixed to the water tank 15 by screwing.

Reference numeral 23 denotes a drying drum rotatably supported within the dryer main body 22, and a large number of hot air suction ports 24 are provided at the front peripheral edge of the drum 23.

Further, a recess 23' is formed at the rear of the drum 23, and this recess 23' is provided with a large number of hot air discharge ports 25, and a filter cover 26 is provided in a detachable manner. 27 is installed.

28 is arranged at the rear of the drum 23 and has a fan 2 inside.
9 is a built-in fan case, 30 is an air pipe communicating with the fan case 28, and 31 is a hot air intake port 2 at the front of the drum 23.
4 and has a heater 32 inside.

33 is a heat exchanger whose both ends are connected to the blower pipe 30 and the intake pipe 31, respectively, and has a condensing pipe 34, radiation fins 35, etc., and this heat exchanger 33 is connected to the water storage overflow port 16 of the water storage tank 15. It is placed at the bottom.

36 is a drain port through which water droplets cooled and separated within the heat exchanger 33 are discharged.

37 connects the drum 23 and fan 29 to a motor (not shown)
This is a belt for driving by.

38 is a door attached to the front of the dryer main body 22.

39.40 is a washing time switch and a drying time switch.

To explain the operation in the above configuration, first, after putting laundry and detergent into the washing tub 6, the washing time switch 39 and program selection switch (not shown) are set and started. The programmed contacts and cam operations, the water level control switch (not shown), the clutch built into the bearing housing 9 (not shown), the electromagnetic water supply valve 4, the electromagnetic drain valve 10, etc. are interlocked.
So-called fully automatic washing is performed in the following order: water supply, washing, drainage, rinsing (water supply, agitation, drainage, dehydration repeated), and dehydration.

In this case, if the program setting by the selection switch includes rinsing water storage, the pump 19 is activated after the final rinsing in the progression of the above steps.
The rinsing liquid in the washing tank 7 and the dewatering tank 6 is pumped into a water storage tank 15.

That is, after the final rinse is completed, the water level control switch detects that there is no water in the water tank 15 and operates the pump 19 to pump up water.

When using the stored water for the next wash, turn on the cock 1.
8 is opened to supply water from the water tank D5 to the washing tub 6, and at the same time, the time switch 39 is set to the start position, and the insufficient amount of water is supplied through the water supply valve 4.

The subsequent steps are as described above.

Further, when storing washing liquid in the water storage tank 15, the same operation is performed.

When the laundry that has been washed, rinsed, and dehydrated is put into the drying drum 23 and the drying time switch 40 is turned on, the motor (not shown) is driven, the drum 23 and the fan 29 are rotated, and the heater is turned on. 32 is energized.

The air in the drum 23 is sucked in by the fan 29 and sent to the blast pipe 30, and then passes through the heat exchanger 33.
When passing through the intake pipe 31, the air is heated by the heater 32 to become hot air, which is then introduced into the drum 23 again to dry the material to be dried.

In such an air circulation path, the high-temperature and humid air generated in the drum 23 is condensed into water droplets in the condensing pipe 34 of the heat exchanger 33, which is constantly cooled by the water stored in the water storage tank 15, and is discharged as water. It passes through the port 36, overflow hose 13, and drain hose 12, and is discharged to the outside of the machine.

As is clear from the above explanation, according to the present invention, the heat exchanger is cooled with water in the water tank instead of conventionally using room temperature air, so the temperature of the heat exchanger can be lowered. As a result, the effect of condensing moisture in the dry air is improved, the drying time is shortened, and the drying efficiency is improved.

Alternatively, since a fan device for air cooling is not required, the cost can be reduced.

Furthermore, the water tank is equipped with a water level control device that operates a pump to store the rinse water after rinsing in the tank when there is no water in the tank, and the dryer is normally not operated. Considering that the drying process is carried out by putting the dehydrated laundry into the drum after the final rinse, water is always stored in the water tank during the drying operation.
The heat exchanger is reliably cooled by water, and the dehumidifying capacity can be increased without requiring any special operation by the user, and the drying performance can be improved.
