Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a dehydrating washing machine.

[Prior Art] Conventionally, as a dehydrating washing machine, a rotary drum with a large number of small holes perforated in the peripheral wall is supported rotatably around a horizontal axis in a water tank, and water is contained in a water tank. By rotating the rotating drum, the items to be washed in the rotating drum are washed, and by rotating the rotating drum with water removed from the water tank, the items to be washed are dehydrated. In addition, in the above-mentioned dehydrating washing machine, the lid body for opening and closing the opening for loading and unloading the laundry has almost the same shape as the opening, and one edge of the lid body is supported by a hinge. This allows the lid to be moved between a closed position where it joins to the periphery of the opening and a released position where the opening is opened. When placed in each position, the lid is held in that position by a locking device.

[Problems to be Solved by the Invention] However, in the above-mentioned apparatus, when a larger load is applied to the lid from the inside of the rotating drum due to the object to be washed stored in the drum during the washing operation, The lid may be deformed and damaged, the connection between the lid and the opening may become misaligned, making it difficult to open and close smoothly, or a large load may be applied to the locking device, causing the lid to be incorrectly locked. There is also a problem that the sliding groove may be released due to the spherical shape, and that it is complicated to form the sliding groove to match the shape of the sphere, resulting in considerable difficulty in manufacturing it. In order to prevent this, it became necessary to reduce the amount of laundry to be washed per wash, making it less convenient to use, and it became necessary to make the locking device more rigid, leading to a rise in manufacturing costs. .

The present invention has been made in order to solve the above-mentioned problems, and its purpose is to ensure that the force applied to the lid body by the object to be washed during the washing operation is stopped within the inner tank through the lid body. This makes it possible to increase the amount of laundry that can be processed, and also simplifies the structure of the locking device and the pivot structure for the lid, reducing the operating force for opening and closing the lid. The objective is to provide a dehydrating washing machine that is always stable and light.

[Means for Solving the Problem] In order to achieve this object, the invention according to claim 1 includes: an outer tank; a support body rotatably supported around a vertical axis within the outer tank; A substantially spherical 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 that performs a washing operation by rotating the inner tank around the horizontal axis or the inclined axis with water contained in the outer tank so that the water level reaches the outer tank; A dewatering drive that performs a dewatering operation by rotating the support body integrally with the inner tank at high speed around the vertical axis without rotating the inner tank around the horizontal axis or the tilted axis when an object is accommodated therein. an opening for putting in and taking out things to be washed is formed in the upper part of the inner tank, and a lid body that can open and close the opening is provided on the inner surface of the inner tank, and the lid body placed in the closed position opens the outside of the tank. The lid is configured to engage with the inner circumferential surface of the inner tank at its peripheral edge, and the lid is rotatable at its base around an axis substantially perpendicular to the horizontal axis and within a small range in the vertical axis direction. movably supported.

Further, in the invention according to claim 2, in the invention according to claim 1, the lid body is sandwiched by a recess formed in each abutting portion of a pair of hemispherical members forming the inner tank in a spherical shape. I try to do that.

According to the present invention having the above configuration, water is stored in the outer tank and items to be washed are stored in the inner tank,
the inner tank is rotated about a horizontal axis or an inclined axis;
The things that need to be washed are washed. In addition, when the items to be washed after washing are stored in the inner tank, the support body can be rotated integrally with the inner tank around the vertical axis while the inner tank does not rotate around the horizontal axis or the inclined axis. It rotates at high speed and dehydrates the items to be washed. And with this dehydrating washing machine,
When the lid is placed in the closed position, its outer periphery engages with the inner periphery of the inner tank, and since the lid is vertically movable, the lid and the inner periphery of the inner tank engage with each other. are in contact with each other, and the force applied to the lid is reliably received by the inner circumferential surface of the inner tank.

Furthermore, since the lid is rotatably mounted around an axis substantially perpendicular to the rotational axis of the inner tank, there is no risk of the inner tank being erroneously rotated when the lid is opened or closed. Furthermore, since the pivot shaft support of the lid body is rotatably held by a recess formed in the abutting portion of the pair of hemispherical members forming the inner tank, the pivot support structure of the lid body can be simplified. At the same time, the operating force for opening and closing the lid can be reduced.

It is introduced into the inner tank 31 through.

(Operation) Next, an outline of the operation of the dehydrating/drying/washing machine configured as described above will be explained with reference to FIG. 11.

First, with the main body opening/closing lid 4 and the inner tank lid 37 open, the items to be washed are put into the inner tank 31, and then the inner tank lid 37 and the main body opening/closing lid 4 are closed and a start switch (not shown) is turned on. When operated, a series of operations shown in the time chart of FIG. 11 are automatically performed sequentially 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 31 by the first drive mechanism 77, (c) drainage operation by opening the drain valve 85, and (d) middle operation by the second drive mechanism 78. Dewatering operation based on the rotation of the 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 31 by the first drive mechanism 77 (g) Drain valve 8

It should be noted that during each of the above operations (a) to (i), the detected object 102 made of a magnet attached to the inner tank 21 and the detected object 126 (described later) attached to the lid body 37 are connected to the outer tank. 1
Detecting bodies 103, 128 made of Hall elements arranged on 5
By this detection, the positioning of the middle tank 21 or the inner tank 31 is performed by the control device (not shown).

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 31,
The drain valve 85 is closed, the spring clutch 71 is placed in a disconnected state, the first drive mechanism 77 is formed, and the brake body 76 is placed in a braking state to restrict rotation of the inner tank 21. In this state, the water supply valve of the water supply device 81 is opened, water is supplied into the outer tank 15 from the first and second water supply ports 82 and 83, and the water level in the outer tank 15 reaches the inside of the inner tank 31. When the water level reaches the normal water level Wn, the seed section driving motor 51 is rotated in the forward direction, and the inner tank 31 is moved along the horizontal axis X via the first drive mechanism 77.
- Rotated around X. Then, the washing operation is started by the rotation of the inner tank 31.

During this washing operation, the spherical inner tank 31 containing the items to be washed is rotated around the horizontal axis , so-called washing is performed. Therefore,
The amount of water used when washing can be reduced. In addition, since there is almost no twisting or tangles in the items to be washed, the washing operation can be carried out effectively without damaging the cloth, and there is no need to worry about having to correct the kinks or tangles of the items to be washed after the washing operation is finished. It is possible to automatically shift from washing operation to draining operation and dewatering operation without requiring any work.

In addition, when rinsing is performed after washing items,
Similarly to the above-mentioned washing, the inner tank 31 is rotated by the seed part movement motor 51 via the first drive mechanism 77, and by opening the water supply valve of the water supply device 81, the inner tank 31 is drained from the first water supply port 82. Water is supplied toward the outer circumferential surface, and water is also supplied into the inner tank 31 from the second water supply port 83 through the nine ventilation passages, the ventilation port 101, and the rear shaft portion 32, and the inside of the outer tank 15 is rinsed. Water is discharged through the overflow port (path shown) and overflow hose 87 to maintain a constant water level. Therefore, the rinsing water is replaced one after another, the bubbles adhering to the outer peripheral surface of the inner tank 31 are washed away by the water from the first water supply port 82, and the bubbles adhering to the items to be washed in the inner tank 31 are washed away by the water from the first water supply port 82. 2
It is effectively washed away by water from the water supply port 83.

Furthermore, when dewatering is performed after the washing and rinsing of the laundry, the spring clutch 71 is brought into the connected state to form the second drive mechanism 78, and the brake body 76 is brought into the non-braking state to perform the intermediate operation. Rotation of the tank 21 is allowed. When the seed part driving motor 51 is rotated in this state, the inner tank 21 and the inner tank 31 are rotated integrally around the vertical axis Y-Y via the second drive mechanism 78, and the laundry is dehydrated. It will be done.

Therefore, the rotational axis of the inner tank 31 containing the items to be washed can be changed from the horizontal axis
By changing to -Y, it can be done smoothly and in a short time.

Furthermore, when drying is performed after dehydrating the laundry, the inner tank 31 is rotated around the horizontal axis X-X by the seed section driving motor 51 via the first drive mechanism 77, as in the case of washing. At the same time, by energizing the fan motor 96 and the heating heater 98, hot air is generated from the hot air supply device 95, and the hot air flows through the connecting cylinder 100, the ventilation passage 99, and the rear shaft portion 32 to the inner tank. 31 and each small hole 35
is discharged from. Therefore, while transferring the items to be washed,
The drying operation can be performed effectively by applying warm air to the items to be washed. During the drying operation described above, the inner tank 31
The hot and humid air inside is introduced from the overflow port (shown in the diagram), which also serves as a hot air outlet, provided in the outer tank 15, through the overflow hose 87, into the expansion cooling chamber 88, where it is cooled and dehumidified, and then released to the outside. be discharged.

In this state, when the lid body 37 is further rotated toward the closed position, the locking protrusion 124 of the locking member 119 is engaged with the locking recess 125 of the inner tank 31, as shown by the solid line in the figure. The lid 37 is held in the closed position.

As described above, in this embodiment, in order to hold the lid body 37 in the closed position, the locking protrusion 124 of the locking member 119 must be retracted into the recess 115, and the user is required to perform this operation. By forcing, the user can confirm that the entrance/exit 36 is reliably closed.

Further, in this embodiment, the rotation axis Z-Z of the lid body 37 is aligned with the inner tank 3.
Since it is set at a position offset from the rotation center of 1,
When the lid body 37 is opened and closed, the lid body 37 is not moved in close contact with the inner surface of the inner tank 31, and the contact resistance between the two can be reduced and operability can be improved. Furthermore, as shown in FIG. 9, when the lid body 37 is closed, the accommodating portion 12
7 moves along and between the pair of protrusions 129 of the inner tub 31, so there is no fear that the object to be washed will be caught between the lid body 37 and the inner tub 31.

In addition, 130 is a detergent placement part formed on the upper surface of the lid body 37.

On the other hand, when the lid body 37 is placed in the normal closed position shown in FIG. 6, the detected object 126 is placed opposite the detected object 128, as described above. In addition, the lid body 37 is shown in FIG.
When the detection object 126 is slightly released toward the release position as shown by the dotted chain line, the detection object 126 moves out of the detection range by the detection object 128.

Therefore, if the presence or absence of an output from the detection body 128 is monitored by a control device (not shown), the rotation of the inner tank 31 can be started after confirming the closed state of the lid 37, and the lid 37 can be incompletely closed. Since the inner tank 31 is not rotated in the same state, it can be used safely.

Further, when the lid 37 is placed in the closed position, the lid 3
7 is in a position where its outer peripheral edge is engaged with the inner circumferential surface of the inner tank 31, and the entrance/exit 36 is completely closed, so that when washing is performed, etc., the items to be washed stored in the inner tank 31 are Therefore, even if a large force is applied to the lid 37 from inside the inner tank 31, the lid 37 can be moved in the vertical direction, so the outer periphery of the lid 37 can be reliably moved to the inner tank 31. Since it can be brought into contact and engagement with the inner circumferential surface, the force can be reliably received and stopped, and dispersing the force and reducing the force has the same effect and makes the structure of the locking member 119 firm. There's no need. Therefore, the number of items to be washed that can be put into the inner tank 31 can be increased, and the structure of the locking member 119 can be simplified and manufactured at low cost. Furthermore, in this embodiment, since the lid body 37 is rotatably supported around the axis Z-Z orthogonal to the rotational axis X-X of the inner tank 31, the inner tank 31 is rotated when the lid body 37 is opened and closed. It cannot be accidentally moved and therefore no misalignment can occur. Also, a pair of hemispherical members 31a of the inner tank 31.

31b, the shaft support 114 of the lid body 37 is held between the formed bearings 111, so the operating force required to rotate the lid body 37 is always stable and light, and the structure is simplified and manufactured at low cost. can do.

Further, since the opening/closing direction of the lid 37 is set to be the same as that of the main body opening/closing lid 4, operability can be improved.

On the other hand, when assembling the locking member 119 to the lid body 37,
First, as shown in FIG. 10(a), the end of the support shaft 118 on the side opposite to the straddle mounting side is inserted into the hole 116 in the recess 115 of the lid 37. Next, the support shaft 118
is moved upward in Fig. 10 (a), and Fig. 10 (
As shown in b), the other end of the straddle-mounted bearing is also inserted into the hole 116. Then, the locking member 1 is inserted into the recess 115.
19, and the pair of shaft support pieces 120 are engaged with the intermediate portion of the support shaft 118 from above.

Subsequently, as shown in FIG. 10(c), from below the recess 115, the collar 117 of the support shaft 118 and one shaft support piece 120 are removed.
A stopper 121 is fitted to the support shaft 118 between the two. Then, the stopper 121 restricts the movement of the support shaft 118 in the axial direction. Finally, attach the leaf spring 123 to the support shaft 1.
18 and the inner surface of the locking member 119.
0 and locks one end of the locking member 119 to the spring hook piece 122, the installation of the locking member 119 can be easily completed in a short time.

Further, in this embodiment, as shown in FIG. 6, the bearings 111 for the lid 37 are located offset from the joint line L of the inner tank 31, and the joint line L allows each bearing 111
is divided into unequal parts, and the large and small bearings are divided into component parts 111a,
1llb is formed at the joint portion of each hemispherical member 31a, 31b of the inner tank 31. Therefore, if the large bearing accommodates the shaft support 114 of the lid 37 in the component 111a, the lid 37 can be temporarily fixed to one of the hemispherical members 31a, and in that state, both hemispherical members 31a.

31b, both bearings form part 111a.

111b, they can be easily assembled.

Note that this invention is not limited to the above embodiments,
The configuration of each part can also be changed as follows.

(1) The inner tank 21 is formed into a substantially cylindrical shape using a wire mesh or the like, and the mesh on the peripheral wall is used as a drainage part, or a plurality of supports are combined to form a substantially cylindrical framework, and each of the supports is formed into a substantially cylindrical shape. The gap between the parts can be used as a drainage part, or a stainless steel plate or the like can be made into a bottomed cylindrical shape, and a drainage hole can be provided through the peripheral wall and bottom wall.

(2) The inner tank 31 is rotatably supported around an inclined axis that is inclined at a predetermined angle with respect to the horizontal axis XX.

[Effects of the Invention] As is clear from the detailed description above, according to the present invention, by supporting the base of the lid so that it can move within a small range in the vertical direction, the outside of the lid can be moved. The periphery is securely brought into contact with the inner circumferential surface of the inner tub, and therefore, the force applied to the lid body by the object to be washed during the washing operation is reliably received and stopped by the inner circumferential surface of the inner tub, so that the force is dispersed. , has the same effect when reduced. Therefore, the amount of washable items that can be processed can be increased, and the structure of the locking device for the lid can be simplified. Furthermore, since the direction of rotation of the lid body intersects the direction of rotation of the inner tank, there is an effect that there is no risk of the inner tank being erroneously rotated when the lid body is opened/closed. In addition, since the structure of the rotation shaft is extremely simple, there is no force applied to the lid, which means that the force required to open and close the lid is constantly reduced.Furthermore, manufacturing costs can be greatly reduced. There is also.
