Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a washer/dryer that can perform washing, rinsing, spin-drying, and drying processes in an integrated manner.

BACKGROUND OF THE INVENTION A conventional washer/dryer has a structure as shown in FIGS. 3 and 4.

That is, a barrel-shaped water tank 2 is pivotally supported on a horizontal axis within the washing machine main body 1, and a rotating drum 3 is mounted on a drum shaft 4 within the water tank 2.
The interior is rotatable through the Furthermore, the water tank 2 and the rotating drum 3 can be switched between a vertical position and a horizontal position, and the inner peripheral surface of the water tank 2 and the rotating drum 3 are
an external ventilation section 5 surrounded by an outer peripheral surface of the rotary drum 3;
A blowing path for hot air circulation consisting of an internal blowing section 6 is formed inside. 7 is a rotary blade equipped with a hot air circulation function and a washing article agitation function. 8 is a heater. Further, 9 is a drive device for rotating the rotary drum 3, and the rotation motor 10 for switching the aquarium attitude is coupled to a pinion gear 11 and an arc-shaped rack gear 12 that is engaged with the pinion gear 11. . The rack gear 12
is fixed to the wall of the water tank 2. Further, the drive device 9 includes a drum pulley 1 coupled to one end of the drum shaft 4.
3, a drum shaft motor 14 provided close to the drum shaft 4, a motor pulley 15 and a belt 16 that transmit the rotation of the drum shaft motor 14. The water tank 2 is supported by a pair of support legs 17, and the lower end of the support legs 17 is supported by a drainage case 19 having a drainage box 18 having a balancing function in the center. That is, the drain box 18 has the function of a balancer that prevents the washing machine main body from vibrating due to the weight of the washing water stored therein at the time of starting spin-drying and rinsing. A vibration-proof support 20 is interposed between the four corners of the drainage case 19 and the bottom surface of the washing machine main body 1. 21 is a ventilation motor provided on the rear surface of the main body 1 to ventilate hot air containing moisture evaporated from the laundry items when the laundry items are dried; 22 is a ventilation fan; and 23 is a liquid balancer.

With this configuration, the washing, rinsing, and dewatering processes are performed in a vertical position as shown in Fig. 3, and then, by counterclockwise rotation of the binion gear 11 attached to the water tank rotation motor 10, the rack gear 12 is moved and the drum shaft is rotated. 4 is set in a horizontal position and the drying process begins. In the drying process, the rotary drum 3 rotates, the laundry items are lifted and dropped, and are further dried by circulating hot air.

Problems to be Solved by the Invention However, in such a configuration, since the rack gear 12 is provided on the side surface of the water tank 2, the shape of the water tank 2 is also arcuate, and is subject to shape restrictions. In addition, in the process of turning the water tank 2 from the vertical state to the horizontal state, the moment due to the load of the water tank 2 applied to the binion gear 11 gradually increases.
It is also added to the mounting part of the pinion gear 11 of 9. As a result,
Unbalanced loads are applied to the several vibration isolation supports 20 shown in FIG. 4, and the vibration isolation supports 20 are unbalancedly compressed. For this reason, one drainage case will be tilted, and the water tank 2 supported by the support legs 17 on the drainage case 19 will be tilted.This is the reason why it is difficult to control the position of the water tank 2. There was also the problem of wear of the meshing surfaces of the binion gear 11 and rack gear 12 due to dehydration vibration.

Therefore, the present invention realizes a highly reliable rotating configuration of the water tank 2 with a simple configuration.

Means for Solving the Problems The technical means of the present invention for solving the above problems comprises: a substantially spherical water tank; a substantially spherical rotating tank installed in the water tank and having appropriate water passage holes formed therein; and the rotating tank. and a pulsator that rotates coaxially and independently or integrally, a pair of supports that support the water tank on both axes and can rotate at any angle, and at least one suspension attached to each of the supports. and a wire attached to the water tank, a wire folding part such as a fixed pulley fixed above the attachment part of the wire, and a turning motor installed on the bottom of the main body and winding the wire. It is something.

For production The effect of this technical means is as follows.

When the washing, rinsing, and spin-drying steps are completed and the machine moves on to the drying step, the rotation motor installed on the bottom of the main unit is driven, winding the wire attached to the water tank and keeping the water tank in a horizontal position. That is, the wire whose negative end is attached to the water tank is folded back by a fixed pulley or the like fixed above the attachment point and pulled downward by a rotation motor or the like. At this time, centering on a pair of supports,
A moment is generated between the aquarium and the wire attached to the aquarium, causing the aquarium to rotate around the pair of supports.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

In FIGS. 1 and 2, 30 is a rectangular cylindrical main body, and a clothing slot 31 is provided approximately at the upper center of the main body. Reference numeral 32 denotes a substantially spherical water tank, which is provided with a substantially spherical rotating tank 35 and a pulsator 36 in which appropriate water passage holes 33 and a balancer 34 are formed at the top.

The pulsator 36 and the rotating tank 35 are connected to a mechanical section 38 by a drive shaft 37. Furthermore, the drive shaft 37
can be arbitrarily disconnected from the rotary tub 35 by the mechanical section 38 and includes a washing pulley 39, and the washing pulley 39 and the washing motor 40 are interlocked via a belt 41. Further, a drying pulley 42 is attached coaxially with the washing pulley 39 and is linked to a drying motor 44 via a belt 43. Reference numeral 45 denotes reinforcing metal fittings attached to the outer periphery of the water tank 32, each having a rotating shaft 46 on the opposite side, and a bearing 4 fixed to a column 47.
8 is fitted. Here, the rotating shaft 46, support column 47, and bearing 48 constitute a support body. The support column 47 is semi-restrictedly suspended from the main body by two suspensions 49, and the base 50 is fixed to the main body 30, and is connected to a drying fan 51, a heat exchanger 52, and an air duct 53.
A fan motor for the blower fan 51 and a rotation motor 54 for rotating the water tank 32 are fixed to the base 50. 5
5 is a clutch that disconnects the output shaft 56 and the input shaft of the speed reduction mechanism 57. A wire 58 is attached to rotate the water tank 32, and is folded back by a fixed pulley 59, which is a wire folding part provided above the wire attachment part 72 provided in the water tank 32, and is folded back by a fixed pulley 59, which is a wire folding part disposed above the wire attachment part 72 provided in the water tank 32. It is adapted to be wound around a pulley 61 fixed to an output shaft 60 of. Further, reference numeral 62 denotes a ventilation path from the ventilation fan 51, which communicates with an L-shaped ventilation path 63 attached to the outer wall of the water tank 32 through a sliding portion 64. Further, the above-mentioned air blowing path 63 communicates with the inside of the water tank 32 via a heater 65 provided on the top surface of the water WJ 32. 66 is a lint filter provided inside the inner M67 for throwing in the dressing order, and communicates with the intake port 68. The intake port 68 communicates with the blower fan 51 and the heat exchanger 52 via an exhaust path 69, a sliding portion 64, and an exhaust duct 71, forming a series of air circulation paths.

Next, the operation of this embodiment will be explained. FIG. 1 shows the state of the water tank 32 during washing, rinsing, and dewatering processes, and during washing, the drive shaft 37 of the rotating tank 32 is positioned perpendicular to the installation surface of the main body 30. At this time, the pulsator 36 is connected to the drive shaft 37 by a mechanical part 38, and is rotated in a constant mode by the power of the washing motor 40. Next, during dewatering, the rotary tank 35 is connected to a drive shaft 37 by a mechanical section 38 in the same manner as the pulsator 36, and rotates at high speed to perform a dewatering process. At this time, the vibration of the rotating tank 35 is transmitted from the water tank 32 to the two pairs of suspensions 49 via the bearing 48 and is damped. Next, when the above dehydration process is completed, the clutch 5
5 is connected to a deceleration mechanism 57, and the rotating motor 54 is driven for a certain period of time.

Then, the pulley 61 attached to the output shaft 60 of the deceleration mechanism 57 winds up the wire 58 whose other end is attached to the water tank 32, so that the water tank 32 rotates around the rotation axis 46 to a horizontal state.

At this time, since the wire 58 is folded back at the upper part of the wire attachment part of the water tank 32 by the fixed pulley 59, the rotation axis 46
A moment centered on can be applied in a certain direction. Further, since the rotation motor 54 is fixed on the base 50 attached to the main body 3o, the moment when the water tank is rotated is reduced as in the conventional example. Furthermore, this embodiment has a flexible rotation structure using the wire 58 and does not use a rack gear and pinion gear as in the conventional example, so that adverse effects such as wear due to dehydration vibration can be avoided.

Effects of the Invention As described above, the present invention has a configuration in which the wire attached to the aquarium is wound and rotated, so there is no restriction on the shape of the aquarium, and the wire is folded back at the upper part of the wire attachment part of the aquarium using a fixed pulley. Therefore, a moment centered around the rotation axis can be applied in a fixed direction.Furthermore, since the rotation motor is fixed on a base attached to the main body, the aquarium will not tilt due to the moment when the aquarium is rotated, and the aquarium will not tilt. The position can be easily set.Furthermore, since it has a flexible rotation structure using wires, it is possible to provide a washer/dryer that is free from the effects of wear and the like due to dehydration vibration.
