Description

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

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

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. When washing, multiple amounts of water are required, and the washing process tends to cause the objects to be washed to become twisted or tangled.If these twists and entanglements are not corrected 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, with this second type, at the end of the washing operation, the object to be washed is unevenly distributed at the bottom of the rotating drum due to its own weight, causing the center of gravity of the rotating drum to be unbalanced, 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. To provide a machine without dehydration washing which can immediately start dehydration operation after completion of dehydration.

Furthermore, it is an object of the present invention to easily mold a spherical inner tank for accommodating items to be washed using synthetic resin, and to attach a driven gear that meshes with a driving gear on the outer periphery of the inner tank. It is an object of the present invention to provide a dehydrating washing machine which can be easily installed and whose driving structure can be simplified.

[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, An inner tank is rotatably supported on the support body around a horizontal axis or an inclined axis tilted at a predetermined angle with respect to the horizontal axis, and has a peripheral wall with a large number of small holes. a washing driving means for washing by rotating the inner tank around the horizontal axis or the inclined axis with water contained in the outer tank and items to be washed stored in the inner tank; and a dewatering drive means for dewatering by rotating the support integrally with the inner tank at high speed around the vertical axis while the items to be washed after being washed are housed in the inner tank, and the inner tank has a substantially hemispherical shape. A pair of members are connected to each other at opposite edges, and one member is provided with a driven gear on the outer periphery that meshes with a driving gear connected to a motor. The tank is designed to rotate.

[Function] In the dewatering and washing machine configured as described above, water is stored in the outer tank, and items to be washed are stored in the inner tank, and the inner tank is rotated along the horizontal axis or the inclined axis. The washing machine rotates around the washing machine and washes the clothes to be washed. Further, while the items to be washed after being washed are stored in the inner tank, the support body is rotated at high speed around the vertical axis integrally with the inner tank, thereby dewatering the items to be washed. Furthermore, in this dehydrating washing machine, the spherical inner tank can be easily divided into a pair of roughly hemispherical members and molded using synthetic resin, etc., and a driven gear that meshes with the driving gear is attached to the outer periphery of one of the members. By providing this, the drive configuration can be simplified.

During! The center of the bottom of the support plate 26 is formed by a support plate 28 made of iron plate for reinforcement, and an earthen hollow shaft 29 extending downward is protruded and fixed to the lower surface of the support plate 28 . Inside the outer tank 15, the inner tank 26 is rotatably supported around the vertical axis Y-Y by a bearing 31, with the soil hollow shaft 29 passing through the bottom of the outer tank 15 via the seal member 30. has been done.

A large number of annular convex portions 32 correspond to PiIl! of the inner tank 26. In order to reinforce this, they are formed on the outer peripheral surface of the inner tank 26 at predetermined intervals in the vertical direction. Numerous small holes 33 as water drainage parts
is transparently installed in the peripheral wall of the inner tank 26 between the annular protrusions 32 so as to extend in the horizontal direction. Further, a large number of drain holes 34 are provided through the bottom wall of the inner tank 26 and the support plate 28 so as to extend in the vertical direction, and are formed to have a larger diameter than the small holes 33.

As shown in FIGS. 1 to 4, a pair of flat plate portions 35 are provided on both sides of the lower half of the peripheral wall of the middle tank 26, and the lower half of the middle horizontal 26 has a cross section. It is constructed to have a small oval shape. A pair of bearing parts 36 are connected to the inner tank 26
is formed protruding from the outer surface of the upper end of the flat plate part 35 at approximately the center in the vertical direction, and its inner upper end is opened toward the upper half of the inner tank 26 . A band-shaped low-friction member 37 made of a wear-resistant synthetic resin with a small coefficient of friction is fixed to the lower inner circumferential surface of the bearing portion 36, and supports a shaft portion 43 of an inner tank 41, which will be described later.

(Related Structure of Inner Tank) As shown in FIGS. 1, 2, and 5 to 7, the inner tank 41 for accommodating items to be washed consists of a pair of substantially hemispherical members made of synthetic resin. 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 portion 36 also serves as an air blowing port, and the opening of the other shaft portion 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 The distance between the two flat plate portions 35 of the inner tank 26 is approximately the same as that between the two flat plate portions 35 of the inner tank 26. Therefore, if the inner tank 42 is inserted into the middle tank 26 from above, both shaft parts 43 can be moved to the bearing part 3 of the middle tank 26.
6, and in this state, the presser member 46 is screwed to the upper end of the bearing part 36 so as to engage with the upper outer periphery of the shaft part 43. The inner tank 42 is supported in the middle tank 26 so as to be rotatable around the horizontal axis XX while being sandwiched from both sides.

As shown in FIGS. 2 and 8 to 10, a plurality of locking pieces 47 are formed on the edge of the hemispherical member 42a on the - side of the inner tank 41, and on the edge of the hemispherical member 42b on the other side. Engagement hole 48

42b is held in a coupled state. A pair of protrusions 49 for transferring laundry storage are formed at a predetermined interval on the inner circumferential surface of the inner tank 41 so as to extend substantially parallel to the rotational axis of the inner tank 41. Both members 42 of 41
a and 42b are fixed with screws 50. A plurality of bosses 51 for assisting in moving laundry items are formed on the inner circumferential surface of the inner tank 41 so as to extend parallel to the protrusions 49 at a predetermined interval. Part 4
2a and 42b are fixed with screws 52.

In this embodiment, as is clear from FIG.
The top of the washing storage conversion protrusion 49 is inclined so as to gradually approach the rotational axis side of the inner tub 41 from the middle part in the longitudinal direction toward both ends. Therefore, due to the inclined structure of the protrusion 49, sufficient height can be ensured at both ends of the protrusion 49, and the effect of reversing the object to be washed can be improved when washing.

A large number of annular convex portions 53 are located inside the inner part'! In order to reinforce the peripheral wall of the inner tank 41, they are formed at predetermined intervals in the vertical direction on the outer peripheral surface of the inner tank 41, and as shown in FIG. Near the outer periphery, the vertical distance between the annular convex portions 53 becomes narrower, making it possible to withstand concentrated loads during dewatering. A large number of small holes 54 are formed through the peripheral wall of the inner tank 41 between the annular protrusions 53 so as to extend in the horizontal direction, and as shown in FIG.
near the outer periphery in the horizontal plane including the rotation axis X-x, and the protrusion 4
A small hole 54 is essentially formed on the lower side of the base of the inner tank 9 so that water concentrated in these parts can be effectively discharged to the outside of the inner tank 41 during dehydration.

Note that since the hemispherical members 42a and 42b are molded using molds consisting of a male mold and a female mold, the direction of mold removal is along the rotational axis XX. In this case, since the shaft portion 43, the protrusion 49, and the small hole 54 protrude in the horizontal direction, it is easy to remove the mold.

Further, in this embodiment, as is clear from FIG. 1, the diameter of the small hole 54 of the inner tank 41 gradually increases as it moves away from the vicinity of the outer periphery in the horizontal plane containing the rotational axis XX of the inner tank 41. It is configured such that the largest hole is smaller than the small hole 33 in the peripheral wall of the inner tank 26.

As shown in FIG. 1, FIG. 2, FIG. 5, and FIG.
The planar shape thereof is substantially similar to the opening 3 of the main body cover 2 and the opening 17 of the outer tank cover 16. The lid body 56 made of synthetic resin is opened and closed at the entrance 55 of the inner tank 41 by a hinge 57 at the rear edge at a position approximately at the same height as the upper end of the outer tank 15 so as to be in the same direction as the opening/closing direction of the main body opening/closing 114. rotatably mounted;
The hinge 57 is normally biased to rotate in the opening direction (counterclockwise in FIG. 1) by the action of a spring (not shown) provided at the hinge 57.

A large number of small holes 59 are formed in the lid 5 so as to extend vertically.
6 is transparent. The small hole 59 of this lid body 56
As shown in FIG. 11, the small hole 54 of the inner tank 41 is formed by a core 60 having an arc 60a during molding of the lid 56 or each member 42a, 42b of the inner tank 41, and the small hole 59. Arcs 59a and 54a are formed on the inner edge of 54 to prevent items to be washed from getting caught.

The protrusion 61 for changing the laundry storage area is formed on the inner surface of the lid body 56 so as to be continuous with the partial protrusion 70 formed on the inner circumferential surface of the inner tank 41 substantially parallel to the axis of rotation thereof. It is arranged to face the other two protrusions 49 at a predetermined interval. And, this protrusion 61 (partial protrusion 70) and the above-mentioned 2
The protrusions 49 of m are formed every 120 degrees. A plurality of accommodating portions 62 and 63 for accommodating detergent etc. are partition plates 6
4 is defined within the outer recessed portion of the protrusion 61.

Therefore, the detergent stored in the storage portions 62 and 63 in advance falls into the outer tank 15 as the inner tank 41 rotates, and the detergent is prevented from directly adhering to the clothes, causing discoloration of the clothes. can be prevented.

A locking member 66 made of synthetic resin as a locking means is rotatably attached to the front edge of the outer concave portion of the protrusion 61 by a support shaft 67 at the intermediate portion, and has one end attached to the inner! A locking claw portion 66a that can engage with the opening edge of the entrance/exit port 55 of 41 is provided, and a release operation portion 66b is provided at the other end. This locking member 66 is normally urged to rotate in a direction (counterclockwise in FIG. 1) to engage with the opening edge of the entrance/exit port 55 by a spring means (not shown), and this engagement causes the lid body 56 to be rotated. It is designed to be locked and held in the closed position. Further, the locking member 66 of this embodiment is configured such that the mass on the side of the locking claw portion 66a of the support shaft 67 is larger than the mass on the side of the operating portion 66b, and the inner tank 41 is arranged along the horizontal axis X-X. Alternatively, when rotated around the vertical axis Y-Y, centrifugal force generates a rotational force in the direction of locking the lid 56 in the locking member 66. Furthermore, when the lid body 56 is moved in the closing direction, the locking claw portion 66a collides with the opening edge of the inner tank 41, and the locking claw portion 66a temporarily avoids against the spring action and passes through the opening edge. The member 66 is formed with an inclined surface so that the member 66 returns due to the action of a spring and engages with the edge of the opening.

As shown in FIG. 1, FIG. 2, FIG. 5, and FIG.

The outer peripheral portion of the upper end of the inner tank 41 is disposed close to the outer tank cover 16, and the upper part of the driven gear 69 is covered by the outer tank cover 16.

Further, in this embodiment, as is clear from FIG. 1, the outer diameter of the inner tank 41 is larger than the inner diameter of the balancer 27 on the middle tank 26, and when the inner tank 41 is in a stopped state, its entrance and exit are 55 is configured such that the lower edge of the balancer 27 is positioned above the lower edge of the balancer 27, and the items to be washed are placed between the inner tub 41 and the middle tub 26 through the gap between the lower edge of the entrance 55 and the balancer 27. This prevents accidental injection. Furthermore, as shown in FIGS. 1 and 2, the inner tank 41
and the distance between the outer periphery of the inner tank 26 and the outer periphery of the inner tank 26 and the outer tank 1.
The distance between the outer circumferential portion and the outer circumferential portion 5 is configured to increase as it goes downward, thereby preventing the generation of bubbles during washing and rinsing, and ensuring good drainage.

In this state, the seed part driving motor 75 is rotated, and the inner tank 26 is rotated together with the inner tank 41 at high speed around the vertical axis Y-Y via the second drive mechanism 100, thereby dehydrating the items to be washed. It will be done. Therefore, by changing the axis of rotation of the inner tank 41 containing the items to be washed from the horizontal axis X-X to the vertical axis Y-Y, the transition from the washing or rinsing operation to the dewatering operation can be made smoothly in a short time. It can be carried out.

Furthermore, if the laundry is dried after dehydration,
As in the case of washing, the first lateral drive motor 75
The inner tank 41 is rotated around the horizontal axis XX via the drive mechanism 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 rotated. Flexible bellows-shaped connecting cylinder 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 rolled, and warm air is distributed throughout the interior of the inner tub 41, making it possible to perform the drying operation effectively.

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 hose 111 and expanded 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 made of synthetic resin and has a substantially cylindrical shape, and a large number of small holes 33 are made through the peripheral wall thereof as water drainage parts. etc. to form a nearly cylindrical shape, and use the mesh on the peripheral wall as a drainage part, or alternatively, combine multiple pillars, etc. to create a nearly cylindrical frame string, and use the gaps between the pillars as a drainage part. To do so.

(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 above embodiment, a plurality of reinforcing annular protrusions 53 are formed on the outer peripheral surface of the inner tank 41, 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 tub 41 in this way, compared to the case where it is formed on the outer circumferential surface, the annular protrusion 53 is more easily affected when the inner tub 41 rotates during a rinsing operation. It is possible to suppress the generation of bubbles due to agitation of water, and also to prevent the items to be washed from coming into close contact with the inner peripheral surface of the inner tank 41 during drying. drying can be carried out.

4) In the above embodiment, the protrusion 4 used as a washing device is
9.61 and three partial protrusions 7o are provided at intervals of 120 degrees, but for example, in the stopped state shown in FIG. a
Two protrusions may be formed at the same height as the rotational axis of 41 so as to face each other, that is, only two protrusions may be provided at 180 degrees apart.

5) In the above embodiment, the driven gear 69 is internal!
Although it is formed integrally with the outer circumferential step 68 of one member 42a of 41, this UIA#htk↓69 is formed separately from the member 42a and is fitted and fixed to the step 68.

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

The support is rotatably supported within the outer tank about a vertical axis, and the inner tank is rotatably supported within the support about a horizontal or inclined axis, without changing the orientation of the support. 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.

Furthermore, since the spherical inner tank is divided into a pair of roughly hemispherical members, they can be easily molded from synthetic resin, etc., and can be driven to the outer periphery of one member without straddling both members. A wave gear that meshes with the gear can be provided, and the assembly of both members and the drive configuration can be simplified.
