Description

[Detailed description of the invention] The present invention relates to a single-tank fully automatic washing machine that combines a washing tank and a dehydration tank. A water tank is formed between the washing tank and the dryer, and this water tank has the function of pumping water from the washing tank and storing it, making it possible to use the cleaning solution twice. The purpose is to dehumidify the exhaust gas and promote the cleaning effect by increasing the temperature of the stored water.

In conventional washing machines of this kind, i.e., one-tank fully automatic washing machines that combine a washing tank and a dehydration tank, we focused on the uneconomical problem of not being able to use the detergent solution twice. It is well known that water is temporarily stored and reused in a water storage tank provided separately from the washing tank.

It is also well known to attach a dryer to the top of a fully automatic washing machine to facilitate drying.

However, there has been no attempt to improve the performance of both by combining them and interfering with each other's functions.

The present invention attempts to combine the functions of both a washing machine and a dryer to improve their mutual performance.

The aforementioned one-tank fully automatic washing machine that combines a dehydration tank and a washing tank has the uneconomical problem of not being able to use the detergent twice, and the dryer has the disadvantage of not being able to use the detergent twice. Hot air comes into contact with the system and it is then exhausted, but since this exhaust air is hot and humid, it has the disadvantage that when operating indoors, the exhaust must be guided outside through a duct.

The present invention aims to solve these conventional drawbacks and provide an excellent washing machine with dryer.

Examples thereof will be described below with reference to the drawings. In the figure, 1 is an outer casing, 2 is a cover plate placed and fixed on the upper part of the outer casing 1, on which a dehydration lid 3 is rotatably supported and an electromagnetic water supply valve 4 is fixed.

A dewatering receiver 5 elastically supported by the outer casing 1 is disposed in the lower part of the cover plate 2, and a washing tank 6 which also functions as a rotatable dehydrating tank is provided inside the receiver.

A pulsator 7 is rotatably provided at the bottom of the washing tank 6.

8 is a drive motor, 9 is a bearing case, and this bearing case 9
The inlet side of an electromagnetic drain valve 10 that operates in conjunction with a clutch (not shown) installed in the machine is connected to the dewatering tank 5 , and the outlet side of the electromagnetic drain valve 10 is connected to a fuselage hose 1 via a trifurcated pipe 11 .
2 and an overflow hose 13 are connected.

The overflow hose 5 branches and communicates with an overflow port 14 of the dewatering tank 5 and an overflow channel 16 established in a water storage tank 15 fixed to the upper part of the cover plate 2, respectively.

A spring 1 is attached to the drain port 17 provided at the bottom of the water tank 15.
A valve element 19, which is biased in the closing direction at 8, is in contact with the valve element 19 to form a drain valve.

20 is a pump, the suction side of which is connected to the dehydration receiving tank 5 expansion part 5
', and the discharge side is connected to a discharge port 22 opened in the water storage tank 15 via a discharge hose 21.
Connected to 3.

Reference numeral 24 denotes an outer case of the dryer, which is screwed and fixed to the water storage tank 15 with screws.

A bearing casing 25 that also serves as a fan case is fixed to a support plate 25 fixed to the outer case 24, and a rotatable drum 27 is provided.

28 is a dryer motor, which connects the drum 27 with a flat belt 29.
■ Bell) Drive the fan 31 at 30.

32 is a dryer lid pivotally supported on the front plate 33 so as to be openable and closable; 34
．． Reference numeral 35 indicates a time switch for the washing machine and a time switch for the dryer, and a control system component group protected by a shielding plate 36 is fixed at the negative corner of the time switch.

37 indicates an electric heater. 38 is a filter that can be attached to and removed from the drum 27, and 39 is a fan outlet that communicates with the upper opening of the water tank 15.

40 is a drain valve operating knob, and 41 is an exhaust port provided at the top of the water tank 15, which communicates with the upper opening of the water tank 15.

42 is an intake hole opened in the outer case 24, and 43 is a partition plate fixed to the outer case 24, which is located between the fan outlet 39 and the exhaust port 41, and allows air from the outlet 39 to be blown into the exhaust port. 4
Send it to 1.

Note that when the partition plate 43 is inserted into the liquid, air cannot be drawn in, and the air is actually guided through the heat exchange pipe.

In the above configuration, the operation and effect thereof will be explained next. After putting the items to be washed and detergent into the washing tank 6, the time switch 34 and program selection switch (not shown) are set and started. The water supply to the washing tank 6 is controlled by the sequential operation of the programmed contacts built into the switch 34, the water level control switch (not shown), the clutch (not shown) installed in the bearing housing 9, etc. Fully automatic cleaning is performed, starting with washing, draining, rinsing (repeating water supply, stirring, draining, and dewatering), dehydration, and cutting.

In this case, if the program setting by the program selection switch includes water storage, the pump 20 is rotated after washing during the progression of the above process to transfer the washing water in the washing tank 6 to the water storage tank 15. Pump water (the subsequent steps are the same).

To use the stored cleaning liquid for the next cleaning, turn the drain valve operation knob 40 to open the valve body 19, supply the cleaning liquid in the water tank 15 to the cleaning tank 6, and start the time switch 34. position, and supply water for the shortage through the water supply valve 4.

The subsequent steps are as described above. In addition, when wet clothes are inserted into the drum 27 of the dryer with water stored in the water tank 15 and the dryer time switch 35 is set to a predetermined position and the dryer is operated, the intake air from the suction port 42 is transferred to the heater 37. After being heated to become heated dry air, it exchanges heat with the clothes in the drum 27 to become warm air, and this humid air is discharged from the exhaust port 41 by the fan 31 through the fan discharge port 39 and the partition plate 43. Ru.

At this time, the humid air discharged from the fan outlet 39 exchanges heat with the cleaning liquid in the cold water storage tank 15 and releases part of the moisture and heat in the cleaning liquid while reaching the exhaust port 41.

At the same time, the temperature of the cleaning liquid will rise slightly.

As described above, according to the present invention, it is possible to save money by using the detergent solution twice, and by removing part of the moisture and heat from the exhaust air of the dryer, the high temperature of the exhaust air into the room can be reduced. High humidity is alleviated, and at the same time, the temperature of the water stored in the water storage tank increases, improving cleaning performance in the next cleaning.

In particular, in the past, a dehumidifying device consisting of a heat exchanger was separately built into the main body of the dryer to remove moisture from the exhaust gas, but according to the present invention, the water storage tank is dehumidified. It also has the function of a device, and has excellent features such as being able to perform the dehumidifying function without the need for the dryer itself to be equipped with a dehumidifying device.
