Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a washing machine, and particularly to a washing machine that can carry out washing, rinsing, spin-drying, and drying as a series of washing cycles.

"Prior Art" Conventionally, this type of washing machine typically has a rotating shaft 37 of a rotating drum 24 provided in a water tank 35 set in a horizontal direction, as shown in FIGS. 4 and 5. A drum type is known. To give an overview of such a drum-type washing machine, for example, the driving force for rotating the rotating drum 24 around a horizontal axis is transmitted from a motor 31 to a pulley 32, and integrally attached to the rotating drum 24 via a belt 33. The signal is transmitted to the attached pulley 34. On the other hand, the blower fan 21 that rotates during the drying process is driven by the motor 20, and the air flow generated thereby is transferred to the heater 2.
It is heated at 2. The heated air stream is passed through a duct 23 into a rotating drum 24 to dry the dehydrated laundry. This air stream is then discharged into a duct 25, dehumidified in a heat exchanger 26, and Duct 2
7 and circulated to the above-mentioned blower fan 21.

In such conventional washing machines, the rotating shaft 37 of the rotating tram 24 is provided in a horizontal direction, so that the laundry can be rotated in a vertical plane. Compared to this method, the laundry is always efficiently transferred and dropped during the drying process.

However, in the case of this conventional washing machine, when the laundry is stored in the rotating drum 24 in the dewatering process, the laundry is unevenly distributed in the rotating drum 24, and the center of gravity of the rotating body is uneven. This caused problems such as the balance being lost and vibration and noise occurring. Therefore, as shown in Figure 4,
As a vibration and soundproof measure, a method is provided in which the water tank 35 is made heavier; for example, the weight 36 is
However, this had the disadvantage of increasing the M of the product more than necessary and reducing the commercial value of the washing machine.

On the other hand, in order to solve such problems, for example, a washing machine disclosed in Japanese Patent Application No. 1983-36835, which is an earlier application of the present applicant, as shown in FIGS. 6 and 7 attached to the present application, has been developed. something is proposed.

In this washing machine 1', as shown in FIG. 6, a pinion gear t5 is attached to a horizontal shaft 4a that rotatably supports the water tank 4.
．． A worm gear 15I, to which is fixedly attached and driven by the motor 16, meshes with this pinion gear 15a. As the worm gear 15 is driven, the hollow cylindrical water tank 4 starts to rotate, and the rotating shaft 5a of the hollow cylindrical rotary tank 5 provided in the water tank 4 moves to Y in the figure.
It is supported so as to be integrally displaceable between a substantially vertical state coinciding with the axis and a substantially horizontal state coinciding with the X-axis in the figure.

Therefore, in such a washing machine 1', during the dewatering process, the rotating shaft 5. The rotary shaft 5a can be placed vertically, and the rotating shaft 5a can be moved horizontally during the drying process, so that the best usage conditions without the above-mentioned problems can be obtained during any process.

"Problem to be solved by the invention" However, in this washing machine 1', the hollow cylindrical water tank 4 is
Since the product is displaced between the axis and the Y-axis, its rotation locus becomes large relative to the volume of the rotating tank, resulting in a new inconvenience in that the external dimensions of the product become large.

Furthermore, as shown in FIG. 7, in this washing machine 1', one end of the water supply hose 19 is fixed to the water tank 4, so it is necessary to have elasticity sufficient to accommodate the displacement of the water tank 4. It has an elastic structure wrapped around it. For this reason, the water supply hose 19 swings greatly due to vibrations during the dewatering process, and violently collides with the inner wall of the outer tank, the outer wall of the water tank 4, etc., causing a large amount of noise.

In addition, the so-called drying path of this washing machine 1' includes a fan 1
0 is connected to a duct 12 via a heater 11, and this duct 12 is communicated with the inside of the water tank 4, and reaches an exhaust hole provided in the lid 14 through the inside of the rotating tank 5.
There was a problem that hot and humid air was released into the room.

"Purpose of invention" Therefore, the main purpose of this invention is washing.

To provide a convenient washing machine that efficiently performs rinsing, dehydration, and drying.

Another objective of Haku is to provide a washing machine that does not require a weight for vibration and soundproofing during the dewatering process, and that reduces the noise generated by water supply hoses and the like.

Still another object is to provide a washing machine which eliminates the release of moisture during drying and which reduces the size of the device product.

"Means for Solving the Problems" In order to achieve the above object, the main means adopted by the present invention are: a substantially spherical water tank; a washing machine, wherein the water tank is supported so as to be displaceable between a substantially vertical state and a substantially horizontal state, and the rotating tank is integrally displaced in accordance with displacement of the water tank, , a support for supporting the water tank is formed hollow, and this hollow part serves as a water supply passage for supplying water to the water tank and a hot air passage for sending and discharging hot air for drying the inside of the water tank. This is the point.

If the rotating tub is supported almost vertically, the laundry in the rotating tub will rotate around the vertical axis. Similarly, it is suitable for washing, rinsing and dehydration.Then, when the rotating tub is supported almost horizontally, the laundry in the rotating tub will rotate around the horizontal axis, for example. Like the conventional drum type, it is suitable for drying.

On the other hand, if the water supply passage and the hot air passage are provided in the support body that supports the water tank, there will be no ribbing in the water supply passage, which does not require a coiled portion to provide the elastic structure of the water supply hose. In addition, in the hot air passage, a closed hot air circulation path is formed to enable air cooling and dehumidification.

Furthermore, since the water tank and the rotating tank have a substantially spherical shape, the rotation locus is small compared to the capacity of the water tank.

"Effects of the Invention" According to this invention, it is possible to alternately rotate the laundry around the horizontal axis and around the vertical axis, so that the best condition can be achieved both during spin-drying and during drying. It can be used in

Also, since there is no need for a weight for vibration and soundproofing,
Compared to conventional devices, the entire device can be made lighter, and by reducing the rotation locus of the water tank, the device can be made more compact and manufacturing costs can be reduced.

Furthermore, since a portion of the water supply path and the hot air path are incorporated into the support that supports the water tank, it is possible to reduce noise caused by vibrations of the hose and the like. Moreover, air cooling and dehumidification by circulation is possible, and release of hot and humid air to the outside of the refrigerator can be prevented.

The above objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

[51°: A cold air blowing chamber 72 is provided that forcibly takes in cold air from outside the refrigerator into the refrigerator through an intake hole 91 formed at the bottom. In this cold air blowing chamber 72,
A cooling fan 60 is installed, and for example, as shown by the thin line arrow in FIG. flowed along.

After circulating in the refrigerator in this way, the cold air is discharged from the exhaust port 92 provided at the upper part of the outer tank 51. At the same time, cooling and dehumidification is performed inside the water tank 54, and as shown in FIG. It turns out.

The water tank 54 has an entrance 511 for the outer tank 51 at its upper part.
．． A lid 64 of an opening corresponding to the lid 64 is attached so as to be openable and closable, and a hollow spherical rotating tank 55 having an opening adjacent to the lid 64 formed at the top is housed inside the water tank 54. . That is, this rotary tub 55 is a washing tub that also serves as a dehydration tank, and is appropriately provided with holes 56 (double water holes in FIG. 2) for dehydration and for introducing hot air. The rotating shaft 55 of the rotating tank 55. is set to coincide with the vertical central axis (Y axis in FIG. 1) of the water tank 54 in the state shown by the broken line in FIG.

In addition, on the inner surface of the rotating tub 55, there is a panfur 56 for rolling laundry and the like. is formed (see Figures 2 and 3).

Next, this rotating shaft 55. vertically passes through the lower part of the water tank 54 and is rotatably supported by a bearing 59 attached to the outside of the water tank 54 .

As shown in FIGS. 2 and 3, near this bearing 59, driving force is applied to the rotating shaft 55 through a belt. A motor 57 is provided for transmitting the signal to the motor.

On the other hand, a motor 66 used for controlling the attitude of the water tank 54 is fixed to the base 53 described above. A single wire 65 that is pulled by forward and reverse rotation is wound around the drive shaft of the motor 66, and both ends of the wire 65 are fixed to the upper end 67° and the bottom 67 of the water tank 54, respectively. . Therefore, when this motor 66 is rotated in either the forward or reverse direction, the hollow horizontal shaft 548.5

The water tank 54 rotates around the center of rotation.

In addition, the water tank 54 is connected to the water supply hose 69m through the water supply hose 69□' through the water supply valve 68 shown in FIG.
9b (see Figure 1) are connected, and both of these
It is introduced into a hollow horizontal shaft 54 and is set so that water can be supplied into the water tank 54 from this horizontal shaft 54 as well, for example.

A detergent box 69c is connected to the water supply hose 69b, and finishing agents, detergents, etc. (not shown) filled therein are appropriately mixed into the water supply, if necessary.

Furthermore, as shown in FIG. 1, the water tank 54 is provided with a drain valve at a corresponding position at the lowest position, with the rotating shaft 55.1 of the rotating tank 55 installed horizontally or vertically. 63m, 631. is provided. This drain valve 63. ．． 63t serves to transfer the sewage in the water tank 54 to the water receiver ff1B9 provided on the base 53, and the water collected here is discharged to the outside of the refrigerator via the drain hose 70.

Next, with reference to FIG. 1, the functions of the embodiment apparatus configured as described above will be explained. FIG. 1 shows the state of the water tank 4 during the washing, rinsing, or dehydration process, and the rotating shaft 551 of the rotating tank 55 is connected to the hollow spherical water tank 5.
4, which is conveniently set on the central vertical axis, that is, the Y axis.

At this time, the rotating tank 55 rotates around the central vertical axis (Y-axis) in accordance with the drive of a motor 57 that is integrally attached to the outer surface of the lower part of the water tank 54 . This rotating tank 5
When 5 rotates in this manner, the dewatering process is carried out smoothly and efficiently according to a predetermined program.

In the case of this washing machine 1'', unlike conventional drum-type washing machines, which spin the laundry with the rotating shaft 55. of the rotating tub 55 horizontal, the rotating shaft 55. Since the dehydration is performed in a state where the laundry is in a state where the laundry is unbalanced, the so-called imbalance caused by uneven distribution of laundry is reduced, and vibrations can be absorbed with a relatively small balancer.

In addition, in terms of drainage in the dewatering process, this wastewater is discharged through the drainage valve 63. The water is then collected in a water tray 89 and discharged through a drain hose 70 as appropriate.

Next, when the dewatering process is finished, the washing machine 1'' enters the drying process, and FIGS. 2 and 3 show the mode during this drying process. When the motor 66 (FIG. 1) is driven, The wire 65 on the upper end 678 side of the water tank 54 is pulled.In response, the water tank 54 begins to rotate, and the support frame 53
．． ．． For example, Y in FIG.
It is moved until it reaches the X-axis position (horizontal position) shown in FIG. 3, which is rotated 90 degrees from the axis position. FIG. 3 shows the rotating shaft 55 of the rotating tank 55. A state in which the is aligned with the X axis is shown.

At this time, if the motor 57 fixed to the water tank 4 is driven at low speed, the rotating shaft 558 will be horizontal, so
The rotating tank 55 rotates around the horizontal axis (X-axis). Therefore, when the rotary tub 55 rotates in this manner, the laundry rolls appropriately and is dried smoothly and efficiently.

When the air forced into the support frame 538 from the ventilation chamber 71 attempts to pass through the support frame 53, it is heated by the heater 61 and becomes warm air, which is turned into a hollow horizontal shaft 54. The water is supplied into the water tank 54 from The warm air that has entered the water tank 54 is further passed through the water hole 56 to the rotating tank 55.
This is where the hydrophilized laundry is dried. The warm air containing a large amount of moisture in the rotating tank 55 passes through the water passage hole 56 on the opposite side to the support frame 53I of the water tank 54,
flows to the side. A cooling fan 60 is installed on the inner surface of the rotating tank 56.
Cooling and dehumidification is performed using the cooling air sent out by the heater, causing moisture to condense and drying the warm air. Thus, suitably dried air enters the support frame 53 through the horizontal shaft 54 and is circulated into the ventilation chamber 71.

Note that the rotating tank 55 is rotated even while the water tank 54 is moving.
It may be driven to rotate at a low speed by the motor 57, or
It may also be stopped. When the drying process is finished in the case of continuous use, the next washing, rinsing, and rinsing processes are started, and the motor 66 is rotated in the opposite direction to prepare for the dehydration process again and is locked to the bottom 67 of the water tank 54. wire 65
will be indexed. Accordingly, the rotating shaft 558 of the rotating tank 55 changes from the horizontal position (FIG. 3) to the vertical position (first
(Figure).
