Description

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

[Prior Art] Conventionally, two primary 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 sink 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 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, 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 hydrophilic action by rotating the drum at high speed around a horizontal axis.

This invention was made by paying attention to the problems that exist in the conventional technology, and its purpose is to create a dehydration flow that can transfer to the dehydration operation, such as twisting and entangling the items to be washed, and staining the fabric. The goal is to provide an opportunity for people to grow their lives.

Furthermore, it is an object of the present invention to provide a dehydrating sink machine that can increase the storage capacity of items to be washed without increasing the overall size, and can process a large amount of items to be washed at the same time. There is a particular thing.

[Means for Solving the Problems] In order to achieve the above object, the dehydration flow combinator of the present invention includes an outer tank and a support rotatably supported within the outer tank around a vertical axis. and an inner tank rotatably supported within the support body around a horizontal axis or an inclined axis tilted at a predetermined angle with respect to the horizontal axis, and having a large number of small holes in the peripheral wall, and a water level inside the inner tank. a washing drive means for washing by rotating the inner tank around the horizontal axis or the inclined axis with water being stored in the outer tank and items to be washed in the inner tank; a hydrophilic driving means for dewatering by rotating the support body 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; The support body is formed into a substantially cylindrical shape, and the inner tank is formed into a substantially spherical shape.

[Function] In the dewatering and draining 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. The washing machine rotates around the washing machine and washes the clothes to be washed. Further, with the items to be washed stored in the inner tank, the support body is rotated at high speed around a vertical axis integrally with the inner tank to dehydrate the items to be washed. In this dehydration draining machine, a support body of the same shape is provided inside the cylindrical outer structure, and an almost spherical inner tank is supported within the support body, so that it can be used inside the tank in a limited space. The capacity of the tank can be increased, and a large amount of items to be washed can be processed at the same time when washing and dehydrating the items.

[Example] Hereinafter, an example of a dehydrating/drying/washing machine embodying the present invention will be described in detail based on the drawings.

A flexible bellows-shaped shield member 18 is installed between the opening 3 of the main body cover 2 and the 'opening 17 of the outer tank cover 16, and is always kept open in both directions regardless of the swinging of the outer tank 15.
3 and 17 are connected in an airtight state to prevent hot air and moisture in the outer tank 15 from entering between the outer tank 15 and the main body case 2, and to prevent vibrations of the outer tank 15 from entering the main body case 1 and the main body case 2. It is configured such that the signal is not transmitted to the main body cover 2.

(Related structure of the inner tank) As shown in FIGS. 1 and 2, the inner tank 26 as a support is made of synthetic resin and has a substantially bottomed cylindrical shape similar to the outer WJ 15, with the lower part facing toward the center. It is formed to be inclined downward, and an annular balancer 27 is attached to its upper end. The center of the bottom of the inner tank 26 is formed by a support plate 28 made of a plate for reinforcement, and a hollow soil shaft 29 extending downward is protruded and fixed to the lower surface of the support plate 28 . And middle school 4112
6 is a bearing 3 in the outer tank 15 with the soil hollow shaft 29 penetrating the bottom of the outer tank 15 via the seal member 30.
1 for rotation about a vertical axis Y-Y.

A large number of annular protrusions 32 are formed on the outer peripheral surface of the inner tank 26 at predetermined intervals in the vertical direction in order to reinforce the peripheral wall of the inner tank 26. A large number of small holes 33 serving as water drainage portions extend horizontally between the annular convex portions 32 and the inner tank 26.
The surrounding wall is transparent. 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 horizontal portion 26.
5, the lower half of the middle #126 is configured to have a roughly oval cross section. A pair of bearing parts 36 are connected to the inner tank 26
is formed to protrude 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 has a pair of substantially hemispherical members 42a made of synthetic resin. .

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 top outer surfaces of both members 42a and 42b to protrude horizontally, and one shaft portion 43 has an inner If! A protective net 44 is attached to prevent washing items from flying out inside the shaft 41, and one of the shaft portions 43 and the bearing portion 36 serves as an air outlet, and the opening of the other shaft portion 43 serves as a cover plate. It is blocked by 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 inserted into 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, thereby creating a structure divided into two parts in the vertical direction. The inner tank 42 is supported rotatably around the horizontal axis XX while being held from both sides within the inner tank 26 .

As shown in FIGS. 2 and 8 to 10, a plurality of locking pieces 47 are formed at the edge of one hemispherical member 42a of the inner tank 41, and are engaged with the other hemispherical member 42b. Both members 42a engage the hole 48.

42b is held in a coupled state. A pair of protrusions 4 and 9 for reversing laundry items are formed at a predetermined interval on the inner peripheral surface of the inner tub 41 so as to extend substantially parallel to the axis of rotation of the inner tub 41. , both members 4 of the inner tank 41
2a and 42b are fixed with screws 50. A plurality of bosses 51 for assisting in reversing laundry items are formed on the inner peripheral surface of the inner tub 41 so as to extend parallel to the protrusions 49 at a predetermined interval. The members 42a and 42b are fixed by screws 52.

In this embodiment, as is clear from FIG.
The top of the washing object reversing protrusion 49 is inclined so as to gradually approach the rotation axis side of the inner tub 41 from the longitudinally intermediate portion toward both ends. Therefore, due to the inclined structure of the protrusion 49, a 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 protrusions 53 are formed on the outer peripheral surface of the inner tank 41 at predetermined intervals in the vertical direction in order to reinforce the peripheral wall of the inner tank 41, and as shown in FIG. Near the outer periphery in the horizontal plane including the rotational axis XX, the vertical distance between the annular convex portions 53 becomes narrower, so that the structure can withstand concentrated loads during dehydration. A large number of small holes 54 are formed between the annular convex portions 53 so as to extend in the horizontal direction. ! 41
As shown in FIG.
A small hole 54 is essentially formed near the outer periphery in a horizontal plane including the rotation axis X-X of 1 and below the base of the protrusion 49, and water concentrated in these parts during dehydration is removed. is effectively discharged to the outside of the inner tank 41.

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, this is because the shaft portion 43, the protrusion 49, and the small hole 54 protrude in the horizontal direction.

Easy to cut out.

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 outer circumferential return in the horizontal plane containing the rotation axis x-X of the inner tank 41. Moreover, the largest hole is configured to be 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 lid body 56 made of synthetic resin is formed on the peripheral wall of the main body cover 2 and has a planar shape similar to the opening 3 of the main body cover 2 and the opening 17 of the outer tank cover 16.
A hinge 57 is installed at the rear end 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.
It is attached to the entrance/exit 055 of the inner tank 41 so that it can be rotated to open and close, and is always rotated in the opening direction (counterclockwise in FIG. 1) by the action of a spring (not shown) provided at the hinge 57. It is dynamically energized.

A large number of small holes 59 are transparently provided in the eleven bodies 56 so as to extend in the vertical direction. Then, the small hole 5 of this M body 56
9 and the small hole 54 of the inner tank 41, as shown in FIG.
At the time of molding b, a core 60 having an arc 60a is formed, and arcs 59a and 54a are formed to prevent objects to be washed from getting caught on the inner edges of the small holes 59 and 54.

The protrusion 61 for reversing the laundry is formed on the inner surface of the lid 56 so as to be continuous with the partial protrusion 70 formed on the inner peripheral surface of the inner tub 41 substantially parallel to the axis of rotation. It is arranged to face the other two protrusions 49 at a predetermined interval. The protrusions 61 (partial protrusions 70) and the two protrusions 49 are formed at intervals of 120 degrees. A plurality of storage spaces for storing detergents and the like are defined by partition plates 64 in the outer recesses 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 an opening 55 of the inner tank 41 at one end thereof. A locking claw portion 66a that can be engaged with the edge of the opening is provided, and a release operation portion 66b is provided at the other end. The locking member 66 is urged by a spring means (not shown) to rotate in the direction (counterclockwise in FIG. It is designed to be locked and held in the closed position. Furthermore, the locking member 66 of this embodiment is configured such that the mass of the locking claw portion 66a @ is larger than the mass of the operating portion 66b side than the support shaft 67, 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. Further, 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 the opening edge against the spring action. The member 66 is formed with an inclined surface so that when the member 66 passes through, it returns to its original position due to a spring action and engages with the edge of the opening.

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

A driven gear 69 as a driven body is integrally formed in this stepped portion 68 so as to pass near the lowest part of the inner tank 41 about the rotation axis XX. 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 located above the lower edge of the balancer 27, so that items to be washed are not mistakenly placed between the inner tub 41 and the inner tub 26 through the gap between the lower edge of the doorway 55 and the balancer 27. This prevents it from being thrown in. Furthermore, as shown in FIGS. 1 and 2, #I4 in the above
The distance between the outer periphery of the inner tank 1 and the inner tank 26 and the outer periphery of the inner tank 26 and the outer tank 15 are configured to increase as they go downward, thereby preventing the generation of bubbles during washing or rinsing. In addition to this, drainage is also improved.

It is formed on the rear wall of the outer tank 15 so as to communicate with the lower end of the ventilation passage 119 so as to closely face the rear shaft portion 43 of the inner tank 41. [:] The air is introduced from 121 into the inner tank 41 through the rear bearing part 36 and the rear shaft part 43, and the temperature of the air in the inner tank 41 is increased to dry the items to be washed.

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

Now, in this dehydrating/drying/washing machine, with the main body opening/closing M4 and the inner tank lid 56 open, the items to be washed are put into the inner tank 41, and then the inner tank lid 56 is closed and the storage part 62 is opened.
．． When detergent is poured into the container 63, the main body opening/closing n4 is closed, and a start switch (not shown) is turned on, a series of operations shown in the time chart of FIG. 12 are automatically performed in sequence. That is, first, the main body opening/closing lid 4 is locked in the closed position by a lid locking solenoid (not shown), and is maintained in this locked state until the series of operations is completed.

After the main body opening/closing 114 is locked, the water supply device 104 is activated. Water supply operation, washing operation based on the rotation of the inner tank 41 by the first drive horizontal 99, drainage operation by opening the drain valve 108, dewatering operation based on the rotation of the inner tank 26 by the second drive mechanism 100, and water supply by the water supply device 104. operation, water supply by the water supply device 104 and a squirting 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,
A dewatering operation based on the rotation of the inner tub 411I26 by the second drive mechanism 100 and a drying operation based on the warm air supply by the hot air supply device 115 and the rotation of the inner tank 41 by the first drive mechanism 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 cut off, and the first driving machine tree 99 is formed. The play 4f4c98 enters the braking state and the rotation of the middle #I26 is restricted. In this state, the egg driving motor 75 is rotated, and the first drive mechanism 99
The inner tub 41 is rotated around the horizontal axis X-X through the inner tank 41, and the items to be washed are transferred by the plurality of reversing ridges 49, 61, so that so-called tumble washing is performed. Therefore, compared to a method in which the items to be washed are stirred with water using a pulsator, etc., less water is used when washing because swirling water flow is not used, and the items to be washed do not get twisted or entangled during the washing operation. , the washing action can be performed effectively, and after the washing action is finished,
To automatically perform a washing operation from a washing operation to a draining operation and a dewatering operation without requiring the troublesome work of correcting twists and entanglements of items to be washed.

In addition, when j-rinsing is performed after washing the items to be washed, the inner tank 41 is rotated around the horizontal axis X-X by the ml driving motor 75 via the first drive mechanism 99, as in the case of washing. At the same time, water is supplied from the first water supply port 105 toward the outer peripheral surface of the inner tank 41 by opening the water supply valve of the water supply device 104, and water is supplied from the second water supply port 106 to the ventilation passage 119, the ventilation 0121, and the rear shaft. Water is supplied to the interior of the inner tank 41 through the section 43, and rinsing water is discharged from the overflow day (not shown) to maintain a constant water level. Therefore, the bubbles attached 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, and the bubbles attached to the items to be washed in the inner tank 41 are washed away. The water from the second water supply port 106 effectively washes away the bubbles.

Furthermore, when dewatering is performed after washing and rinsing the laundry, the drain valve and the clutch solenoid are turned on, the spring clutch 94 is connected, and the second
When the drive mechanism 100 is formed, the brake body 98 is brought into a non-braking state, allowing the inner tank 26 to rotate. 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 operation or the rinsing operation to the dewatering operation can be made smoothly in a short time. can be done.

Furthermore, if the laundry is dried after dehydration,
As in the case of washing, the seed part movement motor 75 causes the first
I%@Movement 11The inner tank 41 is connected to the horizontal axis X-X through the M99.
The hot air supply device 11 is rotated around the
5 is supplied into the inner tank 41 through the visible bellows-shaped connecting cylinder 120, the air passage 119, the air outlet 121, and the rear shaft part 43, and is closed by the lid 45. The liquid is discharged from each small hole 54 while avoiding the front shaft portion 43. 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) that also serves as a hot air exhaust port formed on the side wall of the outer tank 5. - This overflow bowl 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 1.1.1 and the like.

(Modifications) Note that the present invention is not limited to the configuration of the embodiment described above, but can be modified and embodied as follows.

(1) In the embodiment described above, the medium M426 is formed of synthetic resin into a substantially cylindrical shape, and the peripheral wall thereof has a large number of small holes 33 as water drainage portions. to form a nearly cylindrical shape, and use the mesh on the peripheral wall as a drainage part, or to create a nearly cylindrical framework by combining multiple pillars, etc., and use the gaps between the pillars as a drainage part. thing.

(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 XX.

(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 peripheral 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 It is possible to suppress the generation of bubbles due to the agitation of the 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 performed effectively.

(4) In the above embodiment, the protrusion 4 for reversing the laundry
9.61 and three partial protrusions 70 are provided at intervals of 120 degrees, but for example, when the inner tank 4 is in a stopped state (not shown in FIG.
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.

[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, a support body of the same shape is provided inside the cylindrical outer tank,
Since the almost spherical inner tank is rotatably supported within the support body around a horizontal axis or an inclined axis, the distance between the axes can be reduced compared to cases where the inner tank has another shape, such as an elliptical cylindrical shape. It can be made large, and the volume of the inner tank can be increased within the limited inner tank.
This does not increase the overall size, and multiple items can be processed simultaneously when washing and dehydrating items.
