Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dehydrating washing machine capable of performing washing, rinsing, and dehydrating operations of laundry items.

[Prior Art] Conventionally, as this type of dehydrating washing machine, there exists, for example, the one shown in the specification and drawings of US Pat. No. 2,171,499. This device has an outer tank that can contain water, and a substantially spherical inner tank that is rotatable around a horizontal axis and a vertical axis inside the outer tank. Around the inner tank, there are a number of holes that allow water to pass through, each opening toward the center of the sphere. The items to be washed are washed by rotating the inner tank around the horizontal axis while supplying water to the outer tank so that the water level reaches the inside of the inner tank containing the items to be washed. It has become. Further, after draining the water in the outer tank, the inner tank is rotated at high speed around the vertical axis to dewater the items to be washed.

[Problems to be Solved by the Invention] However, in the above-mentioned dehydrating washing machine, the numerous holes on the circumferential surface of the inner tank are each opened toward approximately the center of the sphere, so the drilling work for each hole is difficult. It is very troublesome and, for example, when molding resin using a mold consisting of a male mold and a female mold, it is very difficult to release the mold because the bottles for forming the holes all face toward the center of the sphere. Furthermore, there was a problem in that the particles generated in the minute gaps between the molds were generated on the inner surface due to the structure of the dividing surface, causing damage to the clothes.

The present invention has been made to solve the above-mentioned problems, and when molding the hemispherical members of the inner tank, for example, from resin, the dividing surface of the mold is placed outside the inner peripheral surface of the inner tank. This makes it possible to avoid the occurrence of flakes on the inner circumferential surface, facilitates the production of the resin mold for the inner tank, and prevents the user from submerging in water in the inner tank during washing operations. The side portions allow water to enter the inner tank and drain water from the inner tank to the outside very smoothly and quickly, and also to prevent water from flowing from the inner tank to the outside during dewatering operations. It is an object of the present invention to provide a dehydrating washing machine that allows the removal operation to be performed extremely smoothly and quickly.

[Means for Solving the Problem] In order to achieve this object, the dehydration washing machine of the present invention includes an outer tank, a support supported rotatably around a vertical axis in the outer tank, and a support for the support. It is rotatably supported on the body around a horizontal axis or an inclined axis tilted at a predetermined angle with respect to the horizontal f-crest line, and has an inner tank with a number of holes in the peripheral wall, and a water level that reaches the inside of the inner tank. a washing driving means for carrying out a washing operation by rotating the inner tank around the horizontal axis or the inclined axis with water stored in the outer tank and items to be washed stored in the inner tank; and a dewatering drive means for performing a dewatering operation by rotating the support body integrally with the inner tank at high speed around the vertical axis while the washing items are housed in the tank, and the inner tank is A pair of substantially hemispherical members divided in the direction of the rotational axis are connected to each other at their opposing edges, and a large number of holes are opened in the peripheral wall surfaces of both members in the same direction as the rotational axis.

[Function] In the dehydrating washing machine of the present invention having the above configuration, water is stored in the outer tank so that the water level reaches the inside of the inner tank, and the inner tank is opened with the items to be washed stored in the inner tank. By being rotated by the washing drive means, 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 integrally with the inner tank by the dewatering drive means, thereby dewatering the items to be washed.

According to this dehydrating washing machine, a spherical inner tank can be easily manufactured by connecting a pair of substantially hemispherical members at their opposing edges.

In addition, since the peripheral walls of both members have many holes opened in the same direction as the axis of rotation, it is easy to manufacture them when resin molding them, and the dividing surface of the mold can also be placed on the outside surface. Therefore, it is possible to avoid the formation of paris on the inner surface of the inner tank. Furthermore, even if the numerous holes in the inner tank all have the same diameter, the opening area becomes substantially larger as the distance from the axis of rotation of the inner tank increases. Water draining to the outside of the inner tank and water entering into the inner tank are performed extremely smoothly and quickly.

(Operation) Next, an outline of the operation of the dehydrating/drying/washing machine configured as described above will be explained with reference to FIG.

First, with the main body opening/closing N4 and the inner tank lid 37 open, the items to be washed are put into the inner tank 30, then the inner tank lid 37 and the main body opening/closing lid 4 are closed, and a start switch (not shown) is operated. A series of operations shown in the time chart of FIG. 7 are sequentially and automatically performed by 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 by the first drive mechanism 76 (c) drainage operation by opening the drain valve 85 (d) inner tank operation by the second drive mechanism 77 (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 30 by the first drive mechanism 76 (g) Drain valve 8
(h) Dewatering operation based on the rotation of the inner tank 21 by the second drive mechanism 77 (i) Hot air supply by the hot air water supply device 94 and rotation of 1 {y30 by the first drive mechanism 76 Note that during each of the above-mentioned operations (a) to (i), the control device determines the state of the inner tank 21 or the inner tank 30 in the state shown in FIG. 1 based on a detection signal from a sensor (not shown). Positioning is performed.

Next, each of the above operations will be explained in detail.

Now, when washing is performed with the items to be washed stored in the inner tank 30, the drain valve 85 is closed, the spring clutch 71 is in the disconnected state, and the first drive mechanism 76 is formed. The brake body 75 is in a braking state and the middle tank 2
1 rotation is restricted. 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 reaches the normal water level Wn, the tank driving motor 5
1 is rotated, the inner tub 30 is rotated around the horizontal axis XX via the first drive mechanism 76, and a washing operation is started.

During this washing operation, the spherical inner tank 30 containing the items to be washed is rotated around the horizontal axis X-X, and as the rotation progresses, the items to be washed are rolled by the plurality of reversing protrusions 34, 40, etc. While washing, so-called washing is performed. Therefore, the amount of water used when washing can be reduced. Furthermore, since the items to be washed are hardly twisted or tangled, the washing operation can be carried out effectively without causing much damage to the items to be washed. Each hole 35 in the lower part of the inner tank 30 immersed in water is connected to each hole 35 near the horizontal axis X-X.
5 and the diameter in the vertical axis Y-Y direction is almost the same,
As is clear from FIG. 7, the opening area is substantially large, so that water can enter the inner tank 30 and drain water from the inner tank 30 to the outside very smoothly and quickly. Therefore, if water remains in the inner tank 30 forever, the driving load on the inner tank 30 may become larger than necessary.
On the contrary, the amount of water entering the inner tank 30 is not too small and the washing effect is not reduced, so that the washing action can always be carried out efficiently. Moreover, after the washing operation is finished, 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 draining operation and the dewatering operation.

In addition, when rinsing is performed after washing the items to be washed, the tank driving motor 51 is used to
The inner tank 30 is rotated via the first drive mechanism 76 . In addition, by opening the water supply valve of the water supply device 81, water is supplied from the water supply port 82 toward the outer peripheral upper surface 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 replaced one after another, the water from the water supply port 82 effectively washes away the bubbles adhering to the outer peripheral surface of the inner tank 30 and the objects to be washed in the inner tank 30.

Further, when dehydration is performed after the washing and rinsing of the laundry, the spring clutch 71 is connected to form the second drive mechanism 77, and the brake body 75
is placed in a non-braking state, and rotation of the inner tank 21 is allowed. In this state, when the tank drive motor 51 is rotated, the inner tank 21 and the inner tank 30 are rotated at high speed around the vertical axis Y-Y through the second drive mechanism 77, and the objects to be washed are rotated at high speed. Dehydration takes place. Therefore, the rotational axis of the inner tank 30 containing the items to be washed can be changed from the horizontal axis By making this change, it can be done quickly and smoothly.

In this case as well, since the area below each hole 35 in the lower part of the inner tank 30 is substantially large, water drains from the inner tank 30 to the outside very smoothly and quickly, and the water remains in the inner tank forever. It never stays below 30.

In addition, when drying is performed after dehydrating the items to be washed, the inner tank 30 is rotated around the horizontal axis XX by the tank drive motor 51 via the first drive mechanism 76, as in the case of washing. At the same time, by energizing the fan motor 96 and the heating heater 98, the hot air generation source 9 of the hot air supply device 94 is activated.
5 generates hot air, the hot air is supplied into the inner tank 30 via the connecting cylinder 100, the hot air supply passage 99, the air outlet 101 and the rear shaft part 31, and is discharged from each small hole 35. Ru. Therefore, the drying operation can be effectively performed by blowing warm air onto the items to be washed while rolling the items.

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 overflow hose 86.

Now, in this dehydrating/drying/washing machine, the inner tank 30 is composed of a pair of substantially hemispherical members 30a and 30b divided in the direction of its rotational axis (X-X), and their inner reinforcing lips 46 protrude in the horizontal direction. At the same time, a horizontal portion 47a is formed on the outer diameter side of the outer reinforcing lip 47, and
Since the large number of holes 35 are all opened in parallel to the horizontal axis XX, the members 30a and 30b can be smoothly cut out and molded easily.

In particular, when forming a large number of holes 35, as shown in FIG.
3 is provided with a bottle 103a for forming the hole 35, the inner surface edge of each hole 35 formed by mold release can be finished smoothly and beautifully by giving a so-called radius, There is no possibility that so-called debris will appear at the inner hole edge, and therefore, the items to be washed will not be damaged during washing and dewatering operations.

By joining these hemispherical members 30a, 30b to each other at their opposing edges, the substantially spherical inner tank 30 can be easily manufactured. Further, since a plurality of inner reinforcing ribs 46 extending along the joining direction of both members 30a, 30b are integrally formed on the inner surface of the peripheral wall of both members 30a, 30b, sufficient strength of the inner tank 30 can be ensured. Together with both members 30a. Since a plurality of outer reinforcing ribs 47 extending along a direction perpendicular to the joining direction of both members 30a and 30b are integrally formed on the outer circumferential surface of 30b, the inner tank 30 is The strength can be further increased and it can withstand loads from all directions.

Furthermore, since the inner reinforcing rib 46 extends along the rotational axis direction of the inner tub 30, when the inner tub 30 is rotated around the horizontal axis XX and a washing operation or a drying operation is performed,
The inner reinforcing ribs 46 facilitate the transfer of the items to be washed, thereby enhancing the washing and drying effects. Also,
Particularly during the drying operation, a gap is formed by the inner reinforcing rib 46 between the inner surface of the peripheral wall of the inner tub 30 and the object to be washed, so that warm air flows through the gap as well, improving drying efficiency. Furthermore, since the outer reinforcing rib 47 extends along the direction perpendicular to the rotational axis of the inner tub 30, when the inner tub 30 is rotated around the horizontal axis X-X and a washing operation is performed, the outer reinforcing rib 47 The reinforcing ribs 47 prevent the washing water from being stirred indiscriminately, and the generation of bubbles can be reduced.

[Modification] Note that the present invention is not limited to the configuration of the embodiment described above, and can be modified and embodied as follows.

(1) When molding the inner tank 30 with resin, the dividing surface of the mold is the outer surface (
102b) and the inner surface (102a).

(2) When molding the inner tank 30 with resin, set the dividing surface of the mold to the outer surface (
102b) and the inner surface (102a).

(3) When molding the inner tank 30 with resin, the dividing surface of the mold is placed inside the inner surface (102a) where clothing does not come into contact with it.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, in manufacturing each hemispherical member of the substantially spherical inner tank,
For example, in the case of resin molding, the dividing surface of the mold for opening a large number of holes in the peripheral wall of each member in the same direction as the axis of rotation can be placed outside the inner peripheral surface of the inner tank. A smooth and beautiful finish can be achieved without the occurrence of flakes at the end of the inner hole, so that the object to be washed will not be damaged during washing and dehydration. Furthermore, even if the holes in both members have the same diameter, the opening area becomes substantially larger as the distance from the horizontal axis of rotation or the tilted axis of rotation of the spherical inner tank increases. In the lower part that is immersed in water, water drains from the inner tank to the outside and water enters the inner tank extremely smoothly and quickly through each hole with a substantially large opening area. Also, during the dewatering operation, water drains from the inner tank to the outside similarly smoothly and quickly. Therefore, washing and dewatering operations can always be carried out efficiently and easily.
