Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a dehydrating/drying/washing machine capable of performing a series of operations of washing, dehydrating, and drying items to be washed.

[Prior Art] Conventionally, the following two types are known as typical configurations of washing machines having functions other than washing.

The first type consists of an aquarium, a dehydration tank supported rotatably around a vertical axis within the aquarium, and a dehydration tank with a number of small holes perforated in the surrounding wall, and a dehydration tank rotatably supported around a vertical axis within the dehydration tank. Equipped with rotatably supported stirring blades, by rotation of the stirring blades,
This dehydrating washing machine not only washes the items to be washed, but also dehydrates the items after washing by rotating the dehydrating tank at high speed.

The second type includes an aquarium and a rotating drum that is rotatably supported around a horizontal axis within the aquarium and has a large number of small holes in its peripheral wall, and contains water in the aquarium. By rotating the rotating drum, the items to be washed inside the rotating drum are washed, and by rotating the rotating drum while supplying warm air to the items to be washed in the rotating drum, the items to be washed after dehydration are washed. This is a washer/dryer that performs drying.

However, in the first type, the items to be washed are soaked in water in the water tank and are stirred by a stirring blade and washed by a stream of water, so a large amount of water is required for washing. Moreover, the objects to be washed tend to get twisted or tangled with the washing operation, and if these twists and tangles are not corrected after the washing operation is finished, the center of gravity of the dehydration tank will be unbalanced and the dehydration operation will not be carried out smoothly. In some cases, the washing and dehydrating operations could not be performed continuously.

In addition, in the second type, washing is carried out by rotating the rotating drum around the horizontal axis and transferring the items to be washed without depending on the water flow, so compared to the first type. The amount of water used when washing is reduced, and the items to be washed are no longer twisted or tangled. However, in this second type, at the end of the washing operation, the items to be washed are unevenly distributed at the bottom of the rotating drum due to their own weight, causing the center of gravity of the rotating drum to be unbalanced. It was not possible to perform a dewatering operation by rotating a rotating drum at high speed around a horizontal axis. This type of dehydration uses a heavy flywheel-like weight to suppress vibrations.

Therefore, this type of washing machine was heavy and unsuitable for household use.

In view of the problems in the first and second types, a washing machine having the configuration shown in, for example, Japanese Patent Laid-Open No. 196993/1983 has been proposed.

This washing machine includes a bowl-shaped water tank that is displaceably supported between a vertical state and a horizontal state via a support body within the main body, and a large number of small water tanks rotatably housed within the water tank. Equipped with a bowl-shaped rotating tank with transparent holes, the water tank is rotated vertically and rotated around the pulsator to wash and rinse the items in the rotating tank. , With the water tank in a vertical position, the rotating tank is rotated at high speed around the vertical axis to dehydrate the washed or rinsed items on the beach. By rotating the machine around its horizontal axis, it is possible to dry the laundry after dehydration.

[Problem to be Solved by the Invention] However, in this conventional washing machine, in order to change the attitude of the water tank and the rotating tank between the vertical state and the horizontal state, a motor for rotationally driving the rotating tank is required. In addition to the included drive mechanism, it is necessary to provide a drive mechanism including a motor for attitude control, which poses problems in that the addendum is complicated, and furthermore, it becomes large and expensive.

In addition, with this conventional washing machine, the attitude of the water tank must be rotated between vertical and horizontal positions when transitioning from spin-drying to drying, and when starting washing again after drying. Therefore, there was a problem in that the transition of these operations could not be performed in a short period of time.

It is an object of the present invention to provide a dehydrating/drying/washing machine that can perform continuous and effective dehydration/drying/washing.

Furthermore, it is an object of the present invention to be able to freely select and set the location of the hot air supply device as a heating means, and to accommodate the items to be washed from the hot air supply device with a simple ventilation passage configuration. Hot air can be effectively supplied into the inner tank for storing the items to be washed, and the warm air can be smoothly supplied to the inner tank for storing the items to be washed, thereby drying the items to be washed in a short time. Our objective is to provide a dehydrating, drying and washing machine.

Between the hot air supply device and the inner tank, hot air is supplied from the hot air supply device into the inner tank through air outlets provided opposite to the outer tank, the support body, and the inner tank, respectively. A ventilation passage is provided for this purpose.

[Function] In the dehydrating/drying/washing machine configured as above,
With water stored in the outer tank and objects to be washed stored in the inner tank, the inner tank is rotated around a horizontal axis or an inclined axis to wash the objects. Also,
With the items to be washed stored in the inner tank, the inner tank is rotated together with the inner tank at high speed around a vertical axis, and hot air is supplied from the hot air supply device through the air passage and the air outlet. Warm air is supplied into the tank to dehydrate the items to be washed, and with the dehydrated items stored in the inner tank, the inner tank is rotated around a horizontal axis or an inclined axis to remove the water. Things are dried. During this drying process, hot air from the hot air supply device is directly supplied from the air passage through the air outlet into the inner tank without being obstructed by obstacles.

Furthermore, in this dehydrating/drying/washing machine, the hot air supply device as a heating means can be set and arranged at any position outside the outer tank, and the simple air passage structure allows the warm air supply device to be placed inside the inner tank.

During this drying operation, the high-temperature and humid air in the inner tank 33 is transferred to the rear shaft portion 33 of the inner tank 33, which also serves as an air outlet.
On the opposite side, water is discharged into the overflow hose 91 from the overflow port 90 which also serves as a hot air exhaust port formed at 1lIit of the outer tank 10, and the overflow hose 127, expansion cooling chamber 92 and drain hose 123 are connected to the motor. cooling fan 10
By being effectively cooled by the airflow generated at 2, the hot and humid air passing through these hoses and the expansion cooling chamber is cooled and dehumidified, and then discharged to the outside through the drain hose 89. Therefore, the hot and humid air in the inner tank 33 is rarely or almost never discharged to the outside as it is.

Further, in this washing machine, the hot air supply device 94 is connected to the outer tank 10.
Since the warm air supply device 94 can be installed at an appropriate location such as the inside of the main body cover 2 without getting in the way, as in the embodiment, it can also be installed outside or inside the main body cover 2. , the ventilation passage 1 through the ventilation openings 30.34.104 provided opposite to the inner tank 10.21.33, respectively.
Since the configuration is configured to supply hot air from 02, the inner tank 33
Hot air can be supplied using the bearing part, and there is no need to provide a special supply passage, simplifying the configuration.

(Modifications) Note that the present invention is not limited to the configuration of the above-mentioned embodiments, but can be modified and implemented as follows.

(1) In the above embodiment, the inner tank 21 is made of synthetic resin and is formed into a substantially cylindrical shape, and a large number of small holes 28 as water drainage portions are provided in the peripheral wall of the inner tank 21. etc. to form a nearly cylindrical shape, and use the mesh on the peripheral wall as a drainage part. Alternatively, a nearly cylindrical framework can be created by combining multiple pillars, etc., and the gaps between the pillars can be used as drainage parts, or a cylinder with a bottom can be formed from stainless steel, etc., and water can be poured into the peripheral and bottom walls of the cylinder. Making a hole through the middle tank 2
When the inner tank 1 and the inner tank 33 are molded of metal such as stainless steel, it becomes particularly strong and resistant to heat.

(2) The inner tank 33 is rotatably supported around an inclined axis that is inclined at a predetermined angle with respect to the horizontal axis.

(3) In the above embodiment, a plurality of reinforcing annular protrusions 39 are formed on the outer peripheral surface of the inner tank 33, but these annular protrusions 39 are formed on the inner peripheral surface of the inner tank 33.

When the annular protrusion 39 is formed on the inner circumferential surface of the inner tub 33 in this way, compared to the case where it is formed on the outer circumferential surface, when the inner tub 33 rotates during a rinsing operation, the annular protrusion 39 It is possible to suppress the generation of bubbles due to agitation of the water, and also prevent the items to be washed from coming into close contact with the inner circumferential surface of the inner tank 33 during drying, allowing for effective drying. It can be performed.

[Effect of the invention] Since this invention is configured as explained above,
It has the following effects.

The support body is rotatably supported within the outer tank about a vertical axis, and the inner tank is supported rotatably about a horizontal axis or an inclined axis within the support body, without changing the attitude of the support body. Since it is configured to perform washing, dewatering, and drying operations by using the rotation axes of the support body and the inner tank, there is no need to provide a drive mechanism including a motor to control the attitude of the tank, and the structure is simple. It is simple, compact, lightweight, and can be manufactured at low cost.

Further, since the washing, dehydrating, and drying operations are performed in sequence without changing the attitude of the tank, these operations can be performed continuously in a short time.

Moreover, in the individual operations of washing, dewatering, and drying, the inner tank containing the items to be washed is first rotated around a horizontal axis or an inclined axis so that the items to be washed can be washed without using swirling water flow. Because of this, the amount of water used when washing is small, and there is almost no twisting or tangling of the items being washed during the washing operation.
The washing operation can be performed effectively without causing cloth damage, and there is no need for the troublesome work of correcting twists and tangles of the items to be washed after the washing operation is completed. can be automatically migrated to

Furthermore, as the inner tank is rotated around a horizontal axis or an inclined axis, the temperature of the air in the inner tank is increased to dry the items to be washed. The items to be washed are transferred and the drying operation can be carried out effectively.

Moreover, since there is almost no twisting or tangling of the items to be washed during washing and drying operations, the items to be washed can be dried uniformly and quickly with almost no fabric damage, which is extremely effective.

Moreover, the hot air supply device as a heating means can be set and arranged at any position outside the outer tank, and the simple configuration of the air passage allows hot air to flow from the hot air supply device into the inner tank without obstacles. It is possible to dry the items to be washed effectively in a short period of time by supplying them smoothly without being hindered by water.
