Description

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

[Prior Art] Conventionally, this type of dehydrating washing machine includes one shown in the specification and drawings of US Pat. No. 2,171,499, for example. This product is equipped with a spherical inner tank that uses a motor as a drive source to rotate around a horizontal axis when washing, and rotates at high speed around a vertical axis during dehydration. A wave gear meshing with a drive gear connected to the motor is fixed and protrudes in an annular shape.

[Problems to be Solved by the Invention] However, in the conventional dehydrating washing machine, since the wave gear is fixed to protrude in an annular shape from the outer peripheral surface of the inner tank,
Considering the annularly protruding and fixed wave gear, the space between the outer circumferential surface of the inner tank and the support supporting the inner tank or the outer tank must be made large, so there is no opportunity for washing. There was a problem that the body inevitably became larger.

The present invention has been made to solve the above-mentioned problems, and allows the space between the outer peripheral surface of the inner tank and the support supporting the inner tank or the outer tank to be set as small as possible. In this way, the purpose is to downsize and save space in the washing machine.

[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 washing are stored in the inner tank, and the inner tank is rotated along the axis of rotation thereof. A pair of substantially hemispherical members are divided into two parts along a plane perpendicular to the axis of rotation of the inner tank, and are connected to each other at their opposing edges. A concavely cut annular stepped portion is formed, and a wave gear that meshes with a driving gear connected to a motor is formed on the stepped portion, so that the inner tank is rotated by the driving of the motor through the meshing of the two grating wheels. This is what I did.

[Function] In the dehydrating 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 rotates around the horizontal axis or the inclined axis. It is rotated and the items to be washed are 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. Furthermore, with this dehydrating washing machine,
The spherical inner tank can be divided into a pair of almost hemispherical members and easily molded using synthetic resin, etc., and a wave gear that meshes with the drive gear can be installed in an annular step recessed on the outer periphery of one member. In addition to simplifying the drive configuration by providing
It is possible to save space in the washing machine.

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 inner tank 26.
5, the lower half of the middle tank 26 is configured to have a substantially oval shape in cross section. The pair of bearing portions 36 are formed to protrude from the upper end outer surface of the flat plate portion 35 at approximately the center in the vertical direction of the inner tank 26, and the inner upper ends thereof are opened toward the upper half of the inside 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 the inner tank) As shown in FIGS. 1, 2, and 5 to 8, the inner tank 41 for accommodating the items to be washed has its horizontal axis of rotation
A pair of substantially hemispherical synthetic resin members 42a and 42b divided into two along a plane orthogonal to . 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 has an inner I! 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. 4
It is blocked by 5.

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 both hand plate portions 35 of the middle 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 36 of the middle tank 26.
In this state, the holding member 46 is inserted into the bearing portion 3 so as to engage with the upper outer periphery of the shaft portion 43.
6, the inner tank 42, which is vertically divided into two parts, is supported rotatably around the horizontal axis XX while being held from both sides within the middle tank 26. .

As shown in FIGS. 2 and 9 to 11, 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 are coupled to hole 48.

42b is held in a coupled state. A pair of protrusions 49 for reversing laundry items are formed at a predetermined interval on the inner circumferential surface of the inner tub 41 so as to extend substantially parallel to the rotational axis of the inner tub 41,
At the protrusion 49, both members 42a, 4 of the inner tank 41
2b is 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. Member 42a
, 42b are fixed with screws 52.

In this embodiment, as is clear from FIG. 10, the top of the ridge 49 for reversing the object to be washed goes from the middle part in the longitudinal direction to both ends, and gradually moves toward the rotation axis of the inner tub 41. It is inclined to approach. 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 convex portions 53 are provided in order to reinforce the peripheral wall of the inner tank 41. 41 at predetermined intervals in the vertical direction, and as shown in FIG. The spacing is narrower, creating a structure that can withstand concentrated loads during dehydration. The large number of small holes 54 are arranged in the annular convex portion 53 so as to extend in the horizontal direction parallel to the horizontal axis X-X.
As shown in FIG. 2, in particular, near the outer periphery in the horizontal plane including the rotation axis XX of the inner #fJ41 and below the base of the protrusion 49, Small hole 54
are essentially formed, and water concentrated in these parts is effectively discharged to the outside of the inner tank 41 during dehydration.

Since the hemispherical members 42a and 42b are molded using a mold consisting of a male mold 65a and a female mold 65b, 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. Moreover, the largest one is medium WJ26
It is configured to be smaller than the small hole 33 in the peripheral wall of.

As shown in FIG. 1, FIG. 2, FIG. 5, and FIG. 3 and the opening 17 of the outer tank cover 16. The lid body 56 made of synthetic resin is attached to the inner tank 41 by a hinge 57 at the rear end edge at a position approximately at the same height as the upper end of the outer layer 15 so as to be in the same direction as the opening/closing direction of the main body opening/closing lid 4.
It is attached to the doorway 55 so that it can be rotated to open and close, and is always biased to rotate in the opening direction (in the direction of the half-hour hand in FIG. 1) by the action of a spring (not shown) provided at the hinge 57. ing.

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. 12, the small hole 54 of the inner Wj 41 is formed by a core 60 having an arc aOa during molding of the lid body 56 or each member 42a, 42b of the inner tank 41, and the small hole 59.54 Arcs 59a and 54a are formed on the inner edge of the container to prevent objects to be washed from getting caught.

The protrusions 49 are arranged opposite to each other 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 portions 62 and 63 for storing detergent etc. are partition plates 64.
The outer concave portion of the protruding ridge 61 is defined by a section.

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, preventing the detergent from directly adhering to the clothes and discoloring 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 normally urged to rotate in the direction of engagement with the opening edge of the entrance/exit port 55 (in the direction of the half-hour hand in FIG. 1) 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 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 connected to the horizontal thin line 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 stop claw portion 66a temporarily avoids the action against the spring action and passes through the opening edge. The member 66 is formed with an inclined surface so that it returns under the action of a spring and engages with the edge of the opening.

As shown in FIG. 1, FIG. 2, FIG. 5, FIG. 6, and FIG. The stepped portion 68 is formed so that the base end portion of the wave gear 69 as a wave member is integrated with the stepped vertical surface 68b and the stepped horizontal surface 68a around the rotational axis XX. , so that the teeth of the wave gear 69 are reinforced. Further, the wave gear 69 is covered from above by an outer tank cover 16 disposed close to the outer circumference of the upper end of the inner tank 41 . Further, the stepped portion 68 has a stepped horizontal surface 68 parallel to the horizontal axis XX, as shown in FIG.
a and the stepped vertical surfaces 6 and 8b parallel to the vertical axis Y-Y, and each tooth of the wave gear 69 formed inside extends parallel to the horizontal axis X-X. Therefore, it is easy to remove the mold after forming with the male die 65a and the female die 65b, and the shaft portion 43° protrusion 4
9 and the small hole 54 etc. can be easily molded together.

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 may accidentally fall between the inner VI 41 and the inner tank 26 through the gap between the lower edge of the entrance 55 and the balancer 27. It prevents it from being thrown in.

Furthermore, as shown in FIGS. 1 and 2, the distance between the outer peripheries of the inner tank 41 and the middle tank 26 and the distance between the outer peripheries of the middle tank 26 and the outer tank 15 increase as they go downward. This structure prevents the generation of bubbles during washing and rinsing, and allows for good drainage.

1 into the inner tank 41 through the rear bearing part 36 and the rear shaft part 43, the temperature of the air in the inner tank 41 is raised, and the items to be washed are dried.

(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 lid 4 and the inner tank lid 56 open, items to be washed are put into the inner tank 41, and then the inner WJ lid 56 is closed and the storage section 62 is opened.
When detergent is poured into the container 63, the main body opening/closing lid 4 is closed, and a start switch (not shown) is turned on, a series of operations shown in the time chart of FIG. 13 are always automatically performed.

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 a series of operations is completed.

After locking the main body opening/closing lid 4, the water supply device 104 performs a water supply operation, the first drive mechanism 99 performs a washing operation based on the rotation of the inner tank 41, the drain valve 108 opens to drain water, and the second drive mechanism 100 performs a water drain operation based on the rotation of the inner tank 26. Dewatering operation based on rotation,
Water supply operation by the water supply device 104, 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, drainage operation by opening the drain valve 108, and rotation of the inner tank 26 by the second drive mechanism 100. Dewatering operation based on
A drying operation is performed based on hot air supply by the hot air supply device 115 and rotation of the inner tank 41 by the first drive mechanism 99.

When the laundry is to be washed, the drain valve and the clutch solenoid (not shown) are turned off, the spring clutch 94 is disconnected, the first drive mechanism 99 is formed, and the brake The body 98 enters a braking state and the rotation of the inner tank 26 is restricted. In this state, the seed part driving motor 75 is rotated, and the inner WJ 41 is rotated around the horizontal axis XX through the first drive mechanism 99, and the items to be washed are transferred by the plurality of reversing ridges 49.61. , So-called taki-washing (washing) is performed. Therefore, compared to a method in which the items to be washed are stirred together with water using a pulsator or the like, the amount of water used when washing can be reduced because swirling water flow is not used. In addition, since the items to be washed do not get twisted or tangled during the washing operation, the washing operation can be performed effectively, and there is no need for the troublesome work of correcting the kinks and tangles of the items to be washed after the washing operation is completed. It is possible to automatically shift from the washing operation to the draining operation and the dewatering operation without having to do so.

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 from the second water supply port 106 to the ventilation passage 119, the ventilation port 121, and the rear. Inner tank 4 via shaft portion 43
Water is supplied to the inside of the container 1, and Suzuki water is discharged from an overflow port (not shown) to maintain a constant water level. Therefore, inside I! 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. It is effectively washed away by water from the second water supply port 106.

Furthermore, when dewatering is performed after the washing and rinsing of the laundry, the drain valve and the clutch solenoid are turned on, the spring clutch 94 is brought into a connected state, and the second drive mechanism 100 is formed. The brake body 98 is brought into a non-braking state and rotation of the inner tank 26 is allowed. In this state, the seed part driving motor 75 is rotated, and the second drive mechanism 10
0, the inner tank 26 and the inner tank 41 are integrally aligned along the vertical axis Y-
It rotates at high speed around the Y to dehydrate the items to be washed. Therefore, the transition from the washing or rinsing operation to the dewatering operation can be smoothly performed in a short time 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. be able to.

Furthermore, when drying is performed after dehydrating the laundry, the inner 'W! 41 is rotated around the horizontal axis X-X, and by energizing the fan motor 116 and the heating heater 118, hot air generated from the hot air supply device 115 is connected to a flexible bellows-shaped connection.

20 is supplied into the inner tank 41 through the ventilation passage 119, the ventilation opening 121, and the rear shaft portion 43, and is 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 effectively perform the drying operation.

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 gradually removed at , it is discharged to the outside through a drainage hose 109 . In addition, the fan 10 of the motor 75
2 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 embodiment, but can be modified and embodied 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 provided as water drainage portions in the peripheral wall of the inner tank 26. etc. to form a substantially cylindrical shape, with the mesh on the peripheral wall serving as a drainage part. Alternatively, a substantially cylindrical framework is created by combining a plurality of pillars, and the gaps between the pillars are used as drainage parts.

(2) In the above embodiment, the inner tank 41 is rotatably supported in the middle tank 26 around the horizontal axis X-X, but the inner tank 41 is supported at a predetermined angle with respect to the horizontal axis tax-x. Rotatably supported about a tilted tilt axis.

(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, 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. It can be dried directly.

(4) In the embodiment described above, three protrusions 49, 61 and partial protrusions 70 for reversing the items to be washed are provided at 120 degree intervals. For example, in the stopped state shown in FIG. Two protrusions may be formed so as to face each other at the same height as the axis of rotation, that is, only two protrusions may be formed at 180 degrees apart.

(5) In the above embodiment, the wave gear 69 is connected to the inner tank 4.
Although the driving gear 69 is formed integrally with the outer circumferential stepped portion 68 of one member 42a of 1, the driving gear 69 may be formed separately from the member 42a and fitted and fixed to the stepped portion 68.

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

A spherical inner tank is divided into a pair of substantially hemispherical members, and an annular step is formed on the outer periphery of one of the members, which is cut out in a concave shape along a plane perpendicular to the axis of rotation of the inner tank. Since a wave gear is formed in the part, each tooth of the wave gear can be housed in the concave stepped part to eliminate or extremely reduce the amount of protrusion from the outer peripheral surface of the inner tank. By making the distance between the outer peripheral surface of the inner tank and the support or the outer tank as small as possible, the entire dehydration method can be downsized.
