Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dehydrating washing machine capable of washing and dehydrating laundry items.

[Prior Art] Conventionally, the following two types of washing machines have been known as typical configurations.

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. This is a washing machine that washes the items inside the rotating drum by rotating the rotating drum.

[Problems to be Solved by the Invention]However, in the first type, the items to be washed are soaked in water in a water tank and are stirred by a stirring blade to be washed by a stream of water. , A large amount of water is required when washing, and the washing action tends to cause the objects to be washed to become twisted or tangled. There have been cases where the balance has been disrupted and the spin-drying operation cannot be performed smoothly, making it impossible to perform the washing and spin-drying operations continuously.

In addition, in the second type, washing is performed 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, and the center of gravity of the rotating drum becomes unbalanced due to its own weight. It was not possible to perform a dewatering operation by rotating a rotating drum at high speed around a horizontal axis. For this reason, this type of washing machine that performs dehydration uses a heavy weight such as a flywheel 0 to suppress vibrations. Therefore, this type of washing machine is heavy and is not suitable for household use.

This invention was made by paying attention to the point U while existing in the conventional technology, and its purpose is to prevent twisting, entanglement, fabric damage, etc. from occurring in the items to be washed. To provide a dehydrating and washing machine that can sequentially and effectively perform washing, rinsing and dehydration.

Furthermore, it is an object of the present invention to provide a protrusion for reversing the laundry in the inner tank I! By placing it on the inner surface of the body,
To provide a dehydrating washing machine which can increase the strength of a lid body without special reinforcement and can effectively utilize the back side of a protrusion.

[Means for solving the problem] In order to achieve the above object, the dehydrating washing machine of the present invention includes an outer tank, a support body rotatably supported around a vertical axis in the outer tank, , an inner tank supported rotatably around a horizontal axis or an inclined axis tilted at a predetermined angle with respect to the horizontal axis on the support body, and an inner tank having a large number of small holes in the peripheral wall, and a water level reaching the inside of the inner tank. a washing driving means for washing by rotating the inner tank around the horizontal axis or the inclined axis with water stored in the outer tank and items to be washed stored in the inner tank; A dewatering drive means is provided for dewatering by rotating the support body integrally with the inner tank at high speed around the vertical axis while the washing product is housed in the tank, In addition to providing an entrance for taking things in and out, the entrance is covered by a lid so that it can be opened and closed, and a protrusion for reversing the items to be washed is provided on the inner peripheral surface of the inner tub and the lid.

[Function] In the dehydrating washing machine configured as described above, water is stored in the outer tank and objects to be washed are stored in the inner tank, and the inner tank rotates around the horizontal axis or the inclined axis. The washing machine is rotated by the machine to wash the items to be washed. In addition, with the items to be washed stored in the inner tank, the support body is rotated at high speed around a vertical axis together with the inner tank to dehydrate the items to be washed.

Furthermore, in this dehydrating washing machine, multiple protrusions for reversing the laundry are formed on the inner circumferential surface of the inner tank and the lid, so the protrusions on the lid also serve as reinforcement to strengthen the lid. In addition, it is possible to form an accommodating section such as a detergent accommodating section on the opposite surface of the protrusion.

Warm air is introduced into the inner tank 41 from this air outlet 121 through the rear bearing part 30- and the rear shaft part 43, and the inner tank 4
The temperature of the air inside 1 is increased.

(Operation) Next, the operation of the dehydrating/drying/washing machine configured as described above will be explained.

Now, in this dehydrating/drying/washing machine, the main body can be opened/closed 1!4 times.
After putting the items to be washed into the inner tank 41 with the inner tank lid 56 open, the inner tank lid 56 is closed and the storage section 62 is opened.
．． When detergent is put into the container 63, the main body opening lW4 is closed, and a start switch (not shown) is turned on, a series of operations shown in the time chart of FIG. 7 are automatically performed in sequence. That is, first, the main body opening/closing parts 1 and 4 are locked in the closed position by a lid locking solenoid (not shown), and held in this locked state until a series of operations is completed.

Thereafter, a water supply operation by the water supply device 104, a washing operation based on the rotation of the inner tank 41 by the first drive mechanism 99, a drainage operation by opening the drain valve 108, and a dewatering operation based on the rotation of the inner tank 21 by the second horizontal drive mechanism 100. , a water supply operation by the water supply device 104 , a rinsing operation based on water supply by the water supply device 104 and rotation of the inner tank 41 by the first drive mechanism 99 , a drainage operation by opening the drain valve 108 , a drain operation by the second horizontal drive machine 100 of the inner tank 21 A dewatering operation based on the rotation, and a drying operation based on the hot air supply by the hot air supply device 115 and the rotation of the inner tank 41 by the first horizontal driving machine 99 are performed.

When the laundry is to be washed, the drain valve and the clutch solenoid (not shown) are turned off, the spring clutch 94 is turned off, and the first drive side 99 is formed. The brake body 98 enters the braking state, and the rotation of the inner tank 21 is regulated. In this state, the seed part driving motor 75 is rotated, and the inner tank 41 is rotated around the horizontal axis XX through the first drive mechanism 99, and the objects to be washed are rotated by the plurality of reversing protrusions 49, 61, and 70. While being transferred, the so-called washing process is carried out. Therefore, compared to a method in which the items to be washed are stirred with water using a pulsator, the amount of water used when washing can be reduced.
In addition, since there is almost no twisting or entanglement of the items to be washed during the washing operation, the washing operation can be carried out effectively without causing almost any fabric damage. It is possible to automatically shift from the washing operation to the draining operation and the dewatering operation without the need for troublesome work of correction.

Further, when rinsing is performed after washing the laundry, the inner tub 41 is rotated around the horizontal axis X-X by the seed section driving motor 75 via the first drive mechanism 99, as in the case of washing. At the same time, by opening the water supply valve of the water supply device 104, water is supplied from the first water supply port 105 toward the outer peripheral surface of the inner tank 41, and water is supplied from the second water supply port 106 to the ventilation passage 119, the ventilation port 121, and the rear. Water is supplied to the interior of the inner tank 41 via the shaft portion 43, and rinsing water in the outer tank 15 is discharged from a drainage channel (not shown) of an overflow port (not shown) to maintain a constant water level. Therefore, the rinsing water is replaced one after another, and the bubbles adhering to the outer circumferential surface of the inner tank 41 are gently washed away along the spherical outer circumferential surface by the water from the first water supply port 105. Bubbles adhering to the items to be washed inside are effectively washed away by water from the second water supply port 106.

Further, when dewatering is performed after the washing or rinsing of the laundry, the drain valve and the clutch solenoid are turned on, and the spring clutch 94 is connected to the second
When the drive mechanism 100 is formed, the brake body 98 is brought into a non-braking state, allowing the inner tank 21 to rotate. In this state, the seed part driving motor 75 is rotated, and the inner tank 21 and the inner tank 41 are rotated at high speed around the vertical axis Y-Y through the second drive mechanism 100, and the laundry is dehydrated. It will be done. Therefore, the rotational axis of the inner tank 41 containing the items to be washed is changed from the horizontal axis X-X to the vertical axis Y-Y during the transition from the washing operation or the rinsing operation to the dewatering operation without changing the posture of the paddle. This allows the process to be carried out smoothly in a short period of time.

Moreover, when the laundry is dried after dehydration,
As in the case of washing, the seed part movement motor 75 causes the first
The inner tank 41 is rotated around the horizontal axis x-X via the driver side 99, and the fan motor 116 and the heating heater 118 are energized, so that the hot air generated from the hot air supply device 115 is Flexible bellows-shaped connecting body 1
20, ventilation passage 119. Air outlet 121 and rear shaft portion 43
The water is supplied into the inner tank 41 through the holes 54 and discharged from each small hole 54 . Therefore, as the inner tank 41 rotates, the items to be washed are transferred and the drying operation can be carried out effectively.

During this drying operation, the hot and humid air in the inner tank 41 is transferred to the rear shaft portion 43 of the inner tank 41 which also serves as an air outlet.
On the opposite side, the water is discharged into the overflow hose 111 from an overflow port (not shown) that also serves as a hot air exhaust port formed in the OII wall of the outer tank 15, and is further discharged to the outside via the drain hose 109. The hot and humid air is cooled and dehumidified in the overflow hose 111, expansion cooling chamber 112, and drain hose IO9.

In the washing machine of this embodiment, the inner tank lid body 56
Since the protrusion 61 for washing by tapping is formed, the protrusion 61 also plays the role of reinforcing the inner tank lid 56, eliminating the need for reinforcing glue etc. for the inner tank lid 56 and eliminating the need for, for example, the embodiment In this way, the back surface of the protrusion 61 can be effectively used as a detergent storage section. .

If the inner tank 21 and the inner tank 41 are made of metal such as stainless steel, it will be particularly strong and resistant to heat.

(2) In the above embodiment, one seed part movement motor 7
5 constitutes a washing drive means and a dewatering drive means, but each drive means should be constituted by an independently provided drive motor.

(3) In the above embodiment, the inner tank 41 is rotatably supported within the middle tank 21 around the horizontal axis X-X;
The inner tank 41 is rotatably supported around an inclined axis inclined at a predetermined angle with respect to the horizontal axis XX.

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 41 during drying, allowing for effective drying. It can be performed.

(5) In the above embodiment, the protrusion 4 for reversing the laundry
A total of three protrusions 9 and 70 are provided at 120 degree intervals. For example, in the stopped state shown in FIG. 1, the inner tank 4
Two protrusions may be formed so as to face each other at the same height as the first rotation axis, that is, only two protrusions may be formed at 180 degrees apart.

[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. It is configured to perform washing and dewatering operations by using the rotating axes of the support and the inner tank, so washing and dewatering operations can be performed sequentially without changing the posture of the tank. These operations can be performed continuously in a short period of time.

Furthermore, in each washing and dewatering operation, 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 water flow. Therefore, the amount of water used during washing can be reduced, and since there is almost no twisting or entanglement of the items to be washed during the washing operation, it is possible to perform the washing operation effectively without causing almost any damage to the cloth. After the washing operation is finished, there is no need for the troublesome work of correcting twists and entanglements of the items to be washed, and the washing operation can automatically shift to the dehydration operation.

Furthermore, since a plurality of protrusions for reversing laundry items are formed on the inner peripheral surface of the lid that covers the entrance and exit of the inner tank, the strength of the lid can be increased without the need for special reinforcement.
The opposite side of the protrusion can be used effectively.
