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.

[Conventional Prostitution] The following two types are known as typical configurations of conventional washing machines.

The first type consists of a water tank, a dehydration tank that is rotatably supported around a vertical axis, and has a large number of small holes in the surrounding wall, and a dewatering tank that is rotatably supported around a vertical axis within the water tank. This dehydrating washing machine is equipped with a stirring blade, and the rotation of the stirring blade washes the items to be washed in the water tank, and the high-speed rotation of the dehydrating tank dehydrates the items to be washed after washing.

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 immersed in water in a water tank, and the items are stirred by a stirring blade and washed by a water stream. A large amount of water is required when washing, and the washing process tends to cause the items to be washed to become twisted or tangled.If the items to be washed are not twisted or tangled after the washing process, the balance of the center of gravity of the dehydration tank will be affected. The dehydration operation could not be performed smoothly due to the dehydration, and the washing and dehydration operations could not be performed 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 in the lower part of the rotating drum, and the center of gravity of the rotating drum becomes unbalanced due to its own weight, so it continues to rotate in this state. It was not possible to perform a dewatering operation by rotating the drum at high speed around a horizontal axis.

This invention was made by focusing on the problems that exist in the conventional technology, and its purpose is to wash the items without twisting, entangling or damaging the fabric. The purpose is to provide a machine that dehydrates and washes immediately after finishing the process.

Furthermore, it is an object of the present invention that a driven body for rotating the inner tank is arranged at a weight balanced position of the inner tank,
Therefore, the drive body connected to the driven body can be placed at a position where the weight of the support body is balanced, allowing the inner tank to rotate smoothly during washing operations, etc. To provide a dehydrating washing machine that does not induce unbalanced rotation.

[Means for Solving the Problem] In order to achieve the above object, the dehydration washing machine of the present invention includes an outer tank, a support body rotatably supported around a vertical axis within the outer tank, Ji! Tl! An inner tank has a large number of small holes perforated therein, an outer tank contains water so that the water level reaches the inside of the inner tank, and the inner tank is placed horizontally with the items to be washed stored in the inner tank. a washing drive means for washing by rotating around an axis or an inclined axis; and a support body integrally rotated around the vertical axis with the inner tank containing the items to be washed after washing; a dewatering drive means for dewatering by rotating at high speed, and a driven part body is provided on the outer periphery of the inner tank so as to pass near the lowest part, and the driven part body is provided at the bottom of the support below the inner tank. A drive body connected to the inner tank is provided, and the inner tank is rotated by rotation of the drive body.

[Function] In the dehydrating washing machine configured as described above, water is stored in the outer tank and the items to be washed are stored in the inner tank, and the inner tank is rotated along the horizontal axis or the inclined axis. It rotates around the machine and washes the items to be washed. Further, with the items to be washed after being washed stored in the inner tank, the support body is rotated at high speed around the vertical axis together with the inner tank, and the items to be washed are dehydrated within a set time. Furthermore, in this dehydration washing machine, the driven body for rotating the inner tank is arranged at a weight balanced position of the inner tank, and therefore the drive body connected to the driven body is arranged at a weight balanced position of the support body. Therefore, the inner tank can be rotated smoothly during washing operations, etc., and unbalanced rotation of the support body is not induced during dewatering operations.

A band-shaped low-friction member 37 made of a drag-resistant synthetic resin with a small coefficient of friction is fixed to the lower inner circumferential surface of the bearing portion 36, and supports the shaft portion 43 (described later) 1141.

(Seki 3I topography of the inner tank) As shown in Figures 1, 2, and 5 to 7, the inner tank 41 for accommodating the items to be washed consists of a pair of approximately hemispherical containers made of synthetic resin. Member 42a.

42b are connected and fixed to each other at their opposing edges, and are configured to have an approximately spherical shape as a whole. A pair of short cylindrical shaft portions 43 are integrally formed on the outer surfaces of the tops of both members 42a and 42b to protrude horizontally, and one shaft portion 43 prevents objects to be washed in the inner tank 41 from flying out. A protective net 44 is attached to protect this one shaft portion 43.
The bearing part 36 also functions as an air blowing point, and the opening of the other shaft part 43 is closed by a cover plate 45.

The distance between the tips of both shaft parts 43 is configured to be slightly smaller than the inner diameter of the upper half of the inner tank 26, and the outer diameter of the inner tank 41 between the base ends of both shaft parts 43 is It is configured to be approximately the same as the spacing between the two living plate portions 35ral of the middle tank 26. Therefore, by inserting the inner tank 42 into the inner tank 26 from above, both shaft parts 43 can be fitted to the bearing parts 36 of the inner tank 26, and in this state, the holding member 46 can be inserted into the shaft part. By screwing the upper end of the bearing part 36 so as to engage with the upper outer periphery of the inner tank 43, the inner tank 42, which is vertically divided into two parts, is held between both sides in the inner tank 26. It is rotatably supported about axis IIX-X.

In this state, the horizontal movement motor 75 is rotated, and the inner tank 26 and the inner tank 41 are rotated together with the inner tank 41 at high speed around the vertical axis YY through the second drive mechanism 100 to dehydrate the items to be washed. It will be done. Therefore, the transition from the washing action or rinsing action to the hydrophilic action is performed while the items to be washed are stored! By changing the rotation axis of 41 from the horizontal axis XX to the vertical axis fiY-Y, the rotation can be carried out smoothly in a short time.

Furthermore, if the laundry is dried after dehydration,
As in the case of washing, the lateral movement motor 75 causes the first
The inside [41] is rotated around the horizontal axis X-x through the driving aperture 99, and the hot air supply device is turned on by energizing the fan motor 116 and the heating fan 118! The warm air generated from the flexible bellows-shaped connecting body 1
20, ventilation passage 119, ventilation port 121 and rear shaft portion 43
The liquid is supplied into the inner tank 41 through the inner tank 41 and discharged from each small hole 54 while avoiding the front shaft portion 43 closed by the lid 45 . Therefore, as the inner tub 41 rotates, the items to be washed are transferred, and the warm air is distributed throughout the inner tub 41, allowing for effective drying.

Then, the hot and humid air discharged from the small hole 54 of the inner tank 41 is discharged into the overflow hose 111 from an overflow port (not shown) formed in the side wall of the outer tank 15 that also serves as a hot air exhaust port. , this overflow port 111 and expansion cooling chamber 112
After being cooled and dehumidified in the drain hose 109
is discharged to the outside through the Note that the fan 102 of the motor 75 cools not only the motor 75 but also the overflow hose 111 and the like.

(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 embodiment described above, the inner tank 26 is formed of synthetic resin into a substantially cylindrical shape, and a large number of small holes 33 are provided as water drainage portions in the peripheral wall of the inner tank 26. 26 is formed into a substantially cylindrical shape using wire mesh or the like, and the peripheral wall lil[1] is used as a drainage part, or alternatively, a substantially cylindrical framework is created by combining multiple supports, etc., and the gaps between the supports are shall be used as the water drainage part.

(2) In the embodiment described above, the inner tank 41 is rotatably supported within the middle tank 26 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 X-x.

(3) In the embodiment described above, a plurality of reinforcing annular protrusions 53 are formed on the outer peripheral surface of the inner tank 41 (6), but these annular protrusions 53 are formed on the inner peripheral surface of the inner tank 41.

When the annular protrusion 53 is formed on the inner circumferential surface of the inner M441 in this way, compared to the case where it is formed on the outer circumferential surface, the annular protrusion 53 is This prevents bubbles from forming due to agitation of the water, and also keeps the items to be washed inside when drying! ! 441
It is possible to prevent the drying material from coming into close contact with the inner circumferential surface of the inner periphery of the drying material, thereby allowing effective drying.

(4) In the above embodiment, the protrusion 4 for reversing the laundry
9.61 and three partial protrusions 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 provided at 180 degrees apart.

(5) In the above embodiment, the driven body and the drive body are constituted by gears 69 and 92 that mesh with each other, but the driven body is constituted by a driven boob provided on the outer periphery of the inner tank 41. At the same time, the driving part body is constituted by a driving pulley provided at the inner bottom of the inner tank 26, and both bobbles are connected by a belt.

[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 and dewatering operations by using the rotational axis of the inner tank, these operations can be performed continuously in a short time.

Moreover, in the individual washing and dewatering operations, first, the inner tank containing the items to be washed is rotated around a horizontal axis or an inclined axis, so that the items to be washed are washed without using water flow. Therefore, the amount of water used during washing can be reduced, and since the items to be washed do not get twisted or tangled during the washing operation, the washing operation can be carried out effectively without causing fabric damage, etc. After finishing washing, 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 dewatering operation.

Further, the driven body for rotating the inner tank is arranged to pass near the bottom of the inner tank, that is, to pass through the weight balance position approximately at the center of the inner tank, and is therefore connected to the driven body. The drive member body is also arranged at a weight balance position approximately in the center of the middle girder. Therefore, when the inner tank is vertically rotated during the washing operation, etc., the inner tank can be rotated smoothly without any unbalanced load being applied to the bearings at both ends of the ram. Unbalanced rotation is not induced when the unit rotates at high speed, and vibrations of both tanks can be prevented.
