Description

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

[Prior Art] The inventors of this application have already invented a dehydrating/drying washing machine as described below. This dehydrating/drying washing machine has an outer tank that can contain water inside the case body, and a support that is rotatable around a vertical axis inside the outer tank. A pair of bearings are provided to face each other on a horizontal axis, each bearing supports a shaft portion of an inner tub for storing laundry rotatably around the horizontal axis, and a drying means is provided. The structure is such that hot air for drying clothes is supplied from the inside of the inner tank through an opening inside the shaft. Then, the laundry is washed by rotating the inner tub around the horizontal axis while supplying water to the outer tub so that the water level reaches the inside of the inner tub containing the laundry. Also, after draining the water in the outer tank,
The laundry is dehydrated by rotating the support body together with the inner tub at high speed around the vertical axis. Further, hot air for drying clothes is supplied from the drying means into the inner tank through the inner side of the shaft portion to dry the clothes.

[Problem to be solved by the invention] However, in the above-mentioned dehydrating/drying washing machine, the inner tub has a spherical shape, and as mentioned above, the inner tub rotates around the horizontal axis during washing and drying, and the washing machine rotates around the horizontal axis during washing and drying. When drying items, warm air is supplied into the inner tank through the hot air introduction opening, so when the inner tank is rotated around the horizontal axis and washing or drying operations are performed. Laundry tends to gather and stagnate near the center of rotation, that is, near the opening where the amount of rotation is small and is close to the horizontal axis. Therefore, the opening area for introducing and discharging hot air is reduced, which causes problems in introducing and discharging hot air, and the necessary amount of movement of the laundry during washing and drying is not ensured, resulting in insufficient agitation of the laundry. There was a problem.

This invention was made with attention to such problems, and its purpose is to prevent the laundry from rotating near the horizontal axis of rotation of the inner tub during washing and drying operations. This method reliably prevents laundry from gathering and accumulating inside both sides, and also actively removes laundry that tends to accumulate especially near the horizontal axis of rotation during washing and drying operations without hindering the introduction and inflow of hot air during drying. To provide a dehydrating/drying washing machine capable of stirring and moving laundry uniformly over a metal body in an inner tank.

[Means for Solving the Problems] In order to achieve this object, the present invention includes an outer tank for storing washing water, a tank rotatably supported in the outer tank around a vertical axis, and an outer tank for storing washing water. or a support body having a pair of bearings facing each other on an inclined axis inclined with respect to the horizontal axis thereof, and a pair of shaft parts, the shaft parts being supported by the bearings of the support body and extending along the horizontal axis. Or an inner tank that can rotate around an inclined axis, the inner tank has a large number of small holes in the peripheral wall, can accommodate laundry, and supplies hot air for drying clothes into the inner tank. drying means and washing 1. The method comprises an inner tank rotation drive means for rotating the inner tank around a horizontal axis or an inclined axis during rinsing and drying operations, and a dewatering drive means for rotating the inner tank together with a support at high speed around a vertical axis; A flat part extending in a direction substantially perpendicular to the horizontal axis or the inclined axis is provided on the inside corresponding to each shaft part of the inner tank, and a plurality of inwardly protruding parts are provided inside each of the flat parts. It forms a convex part.

[Function] In the present invention having the above configuration, when the inner tub rotation driving means is operated, the inner tub is rotated around the horizontal axis or the inclined axis, and the laundry stored in the inner tub is washed. It will be done.

Further, when the dewatering driving means is activated, the inner tub is rotated together with the support body at high speed around the vertical axis, thereby dewatering the laundry. Thereafter, when the inner tank rotation driving means is operated again and the drying means is operated, hot air is supplied into the inner tank through the inside of the shaft, and drying after dehydration is performed.

In particular, during this washing operation and drying operation, laundry that tends to accumulate near the horizontal axis of the inner tub is caught on the plurality of convex portions with its movement toward the shaft portion being restricted by the flat portion. Aggressively stirred. Therefore, so-called beating washing and drying of the laundry can be uniformly and efficiently carried out over the metal body in the inner tank.

A and the rear shaft portion 2OA and are introduced into the inner tank 30.

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

First, with the main body opening/closing lid 4 and the inner tub lid 37 open, laundry is thrown into the inner tub 30, then the inner tub lid 37 and the main body opening/closing lid 4 are closed, and a start switch (not shown) is operated. Then, a series of operations are automatically performed in sequence under the control of a control device (not shown). That is, (a) Water supply operation by the water supply device 81 (b) Washing operation based on the rotation of the inner tank 30 (c) Drain valve 8
(d) Dehydration operation based on the rotation of the inner tank 21 (e) Water supply operation by the water supply device 81 (f) Water supply by the water supply device 81 and rinsing operation based on the rotation of the inner tank 3o (g) Drain valve Drainage operation by opening 85 (h) Inner tank 21
(i) A drying operation based on the rotation of the inner tank 30 and the supply of warm air by the hot air supply device 94.

(Details of Operation) Next, each of the above-mentioned operations (a) to (i) will be explained in detail.

(Washing, washing, spin-drying, drying operations) Now, when washing is carried out with the main body opening/closing lid 4 and the lid body 37 both closed and the laundry stored in the inner tub 30 in advance as described above, When a switch (not shown) is operated, the drain valve 85 is automatically closed, and the spring clutch 7 is automatically closed.
1 enters the cutoff state, and the brake body 75 enters the braking state to restrict the rotation of the inner tank 21. In this state,
The water supply valve of the water supply device 81 is opened, and water is supplied into the outer tank 15 from the water supply port 82. When the water level in the outer tank 15 reaches the inside of the inner tank 30 and becomes a washing water level (not shown) lower than the normal water level Wn, the seed part movement motor 5
1 is rotated, the inner tub 30 is rotated around the horizontal axis X-X, and the washing operation is started.

During this washing operation, the spherical inner tub 3 containing the laundry
0 is rotated around the horizontal axis X-X, and as the laundry is rotated, the laundry is rolled by a plurality of reversing protrusions 34, 40, etc., and further, the flat part 30 perpendicular to the horizontal axis X-X
The laundry is actively stirred and loosened by the convex part 30c for stirring the laundry provided on b, and the individual laundry items are replaced, thereby efficiently supplying water to the laundry. This improves the washing efficiency by washing by washing. At this time, since the transfer of the laundry around the horizontal axis X-X requires a larger force as the distance from the horizontal axis X-X increases, the shape of the convex portion 30c is made higher and wider as the distance from the horizontal axis X-X increases. are doing. When the laundry is caught on the convex part 30c and lifted upward from below, the centrifugal force acting on the laundry causes the laundry to have a horizontal axis along the side surface of the convex part 30c. Since a force is applied in a direction away from X-X, the laundry does not stay in the vicinity of the horizontal axis X-X.

In addition, when rinsing is performed after washing the laundry, the inner tub 30 is activated by the seed part movement motor 51 as in the case of washing.
is rotated. Furthermore, when the water supply valve of the water supply device 81 is opened, water is supplied from the water supply port 82 toward the upper surface of the outer circumference of the inner tank 30, and the rinsing water in the outer tank 15 passes through the overflow port and overflow hose 87 (not shown). The water level is maintained at a constant level. Therefore, while the rinsing water is being replaced one after another, the water from the water supply port 82 effectively washes away the foam adhering to the outer peripheral surface of the inner tub 30 and the foam adhering to the laundry in the inner tub 30. It will be done.

Furthermore, when dewatering is performed after washing or rinsing the laundry, the spring clutch 71 is brought into a connected state, and the brake body 75 is brought into a non-braking state to allow rotation of the inner tub 21. In this state, when the seed part driving motor 51 is rotated, the inner tub 21 and the inner tub 30 are rotated at high speed around the vertical axis YY, and the laundry is dehydrated.

Further, when the laundry is dried after being dehydrated, the inner tub 30 is rotated around the horizontal axis X-X by the seed section driving motor 51, and the fan motor 96 and By energizing the heating heater 98, hot air is generated from the hot air generation source 95 of the hot air supply device 94, and the hot air is delivered to the connecting cylinder 100, the hot air supply passage 99, and the air outlet 101.
and supplied into the inner tank 30 via the rear shaft portion 2OA,
It is discharged from each small hole 35 and the shaft portion 20B. Therefore, while transferring the laundry, hot air can be applied to the laundry to effectively dry the laundry.

During this drying operation, the hot and humid air in the inner tank 30 flows from an overflow port (not shown) provided in the outer tank 15 that also serves as a hot air exhaust port, through an overflow hose 87, and into the expansion cooling chamber 88.
After being cooled and dehumidified in the overflow hose 87, expansion cooling chamber 88, etc., it is discharged to the outside through the drainage hose 86.

In this embodiment, a cylindrical body 29 made of stainless steel that is not easily deformed by heat and is slidably fitted into a bearing 28A on the side of the inner tank 21 is attached to a convex portion 30c formed protruding from the inner tank 30. A drop-off prevention ring 31 that engages with the side of the bearing 28A is provided at the tip of the shaped body 29, and is inserted into the engagement groove 28a.
Since the inner tub 30 containing heavy laundry is rotated during a washing operation, or when the inner tub 30 is rotated in a heated state during a drying operation, the machine of the shaft portion 2OA The mechanical strength is ensured, wear and deformation of the bearing 28A and the cylindrical body 29 are prevented, and the shaft portion 2OA is prevented from falling off from the bearing 28A. Moreover, since stainless steel has a small coefficient of friction, smooth rotation of the inner tank 30 can be obtained.

Furthermore, in the above embodiment, since the inner tub 30 is integrally formed with the flat part 30b so as to cover the inner opening of the cylindrical body 29, laundry does not enter the inside of the cylindrical body 29 during washing and drying operations. You can prevent it from happening.

Therefore, the laundry is effectively rolled near the center of the inner tub 30, preventing the laundry from becoming an obstacle to the passage of warm air or preventing washing from being carried out effectively, resulting in stable washing. Can perform washing and drying operations.

Further, in the embodiment, the convex portions 30c are formed radially so as to form a fan shape as a whole, and each convex portion 30c
Since the hot air introduction hole 30a is formed in the flat part 30b located between the two, the convex part 30c rotating together with the inner tank 30 acts as a fan during the drying process, and therefore the hot air is heated by centrifugal force. The warm air is also guided outward and introduced into the inner tank 30 from the entire flat part 30b, and is discharged from the entire flat part 30b on the opposite side, so that the warm air flows into the center of the inner tank 30. It passes through the entire interior of the inner tub 30 without passing only through the interior of the inner tub 30, and efficient drying is performed within the inner tub 30. Also, the convex portion 30c prevents the stirring operation during the transfer of laundry during the drying operation. This is carried out efficiently as in the washing operation, and hot air is sufficiently supplied to each item to be washed.

Note that the present invention is not limited to the above-mentioned embodiments. For example, the stainless steel cylindrical body or mesh plate portion may be provided only on the shaft portion on the hot air introduction side, or the flat portion may be formed from individual parts instead of integrally. The configuration can be changed and embodied as desired without departing from the gist of the present invention, such as attachment.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, washing and drying efficiency can be improved by adding stirring action to the transfer movement of laundry during washing and drying operations. It produces the effect that can be achieved.
