Abstract

PURPOSE: To make it possible to lessen the friction of clothing to the wall surface of a dehydrating tank of a fully automatic washing machine which dries the clothing by the operation of a blasting means while applying centrifugal force on the clothing by rotating a pulsator and to efficiently agitate the clothing by increasing the bore of the dehydrating tank upward to a taper shape. CONSTITUTION: The clothing tends to be kicked off outside when the centrifugal force is applied on the clothing by rotating the pulsator 26 by the driving force of a driving motor 27 after the end of washing, rinsing and dehydrating strokes, but the wash is kicked upward of the dehydrating tank 21 along the slope 25 of the pulsator 26. As a result, the clothing is agitated and is dried evenly by the air for drying generated by the blasting means 28. The clothing kicked up by the centrifugal force at this time moves upward while maintaining the contact with the wall surface of the dehydrating tank 21 but the contact resistance of the clothing with the dehydrating tank 21 is lowered and the clothing is made to be kicked up much higher by forming dehydrating tank 21 to the bore of the tapered shape gradually widened toward the upper direction. The agitating effect is thus enhanced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic washing machine which is used in general households, in which washing and rinsing of clothes are performed by a pulsator rotating at a low speed and dehydration is performed by rotating a dehydrating tank at a high speed.

2. Description of the Related Art A conventional fully automatic washing machine has a structure as shown in FIG. That is, the main body 1, a water tank 3 supported by a suspension 2 in the main body 1, a dehydration tank 5 having a hollow dehydration shaft 4 on the top surface and a hollow bottom surface, and the dehydration shaft 4 on the bottom surface of the water tank 3. It is supported by a bearing 6 provided. Denoted at 8 is a washing shaft which is supported by a bearing 7 inside the dehydration shaft 4, and has a pulsator 9 inside the dehydration tub 5.
It has. Further, the washing shaft 8 is linked with the drive motor 10. Denoted at 11 is a blowing means for blowing warm air into the dehydration tank 5. Reference numeral 12 is a fluid balancer fixed to the dehydration tank 5.

[0003]

In such a structure, when the washing, rinsing and dehydration steps are completed, the drive motor 1
With the power of 0, the pulsator 9 is rotated and centrifugal force is applied to the clothes. By this centrifugal force, the clothes are splashed above the dehydration tank 5. Thereby, the clothes are agitated and dried by the blowing means 11.

However, as a problem of this method, the clothes are repelled against gravity so that a strong centrifugal force is required to some extent. For this reason, clothes that are accelerated rapidly rub against the wall surface of the dewatering tank and are easily damaged, and this frictional force is an obstacle to the height at which the clothes are splashed.

Further, there is also a problem that the splashed clothes collide with the bottom of the fluid balancer 12 and hinder stirring.

The present invention is intended to solve the above problems,
By gradually widening the inner diameter of the dehydration tub in an upward direction, friction between the clothes and the wall of the dehydration tank is reduced, and a fully automatic washing machine that effectively stirs the clothes is provided. For the purpose of one.

Further, according to the present invention, by providing a tapered slope below the fluid balancer protruding into the water tank from the inner diameter of the fluid balancer toward the inner diameter of the dehydration tank, full automatic washing for preventing collision of clothes and smoothly stirring. The second purpose is to provide a machine.

Furthermore, the present invention provides a fully automatic washing machine which is provided with an elastic body for the purpose of facilitating the jumping up of the clothes so as to project into the dehydration tub on the pulsator, thereby effectively stirring the clothes. The third purpose is to provide.

In order to achieve the above first object, the first means of the present invention comprises a main body, a water tank supported by a suspension in the main body, and a bearing mounted on the bottom surface of the water tank. A dehydration shaft, a dehydration tub fixed to this dehydration shaft and having a fluid balancer attached to the top, a washing shaft axially supported in the dehydration shaft, a pulsator attached to this washing shaft, and warm air in the dehydration tub. The present invention provides a fully-automatic washing machine including an air blowing unit for blowing and a drive motor that works in conjunction with a washing shaft and a dehydration shaft, in which the inner diameter of the dehydration tub is gradually widened upward.

In order to achieve the above-mentioned second object, the second means of the present invention comprises a main body, a water tank supported by a suspension in the main body, a dehydration shaft mounted on the bottom surface of the water tank by a bearing, and A dehydration tub fixed to the dehydration shaft and having a fluid balancer attached to the upper part thereof, a washing shaft axially supported in the dehydration shaft, and a pulsator attached to the washing shaft,
The dehydrator is equipped with an air blower for blowing hot air and a drive motor that works in conjunction with the washing shaft and the dehydrator shaft, and extends downward from the fluid balancer inner diameter to the dehydrator tub inner diameter below the fluid balancer protruding into the dehydration tub. It is intended to provide a fully automatic washing machine having a tapered inclination up to.

In order to achieve the third object, the third means of the present invention is a main body, a water tank supported by a suspension in the main body, a dehydration shaft mounted on the bottom surface of the water tank by a bearing, and A dehydration tub fixed to the dehydration shaft and having a fluid balancer attached to the upper part thereof, a washing shaft axially supported in the dehydration shaft, a pulsator attached to the washing shaft, and a blowing means for blowing warm air into the water tub.

[0012]

According to the first means of the present invention, when the washing, rinsing and dehydration steps are completed, the pulsator is rotated by the power of the drive motor to apply a centrifugal force to the clothes. The centrifugal force pushes the clothes up above the dehydration tank. This causes the clothes to be agitated and dried by the blowing means, but the clothes repelled by the centrifugal force move upward while contacting the dehydration tank wall surface. At this time, by gradually widening the inner diameter of the dehydration tank upward,
Since the dehydration tank wall surface inclines a part of the reaction force of the collision of the clothes to which the force is applied in the horizontal direction by the centrifugal force in the other direction, the contact resistance between the clothes and the dehydration tank wall surface can be reduced. Further, by rotating the dehydration tank at a high speed, for the same reason as described above, the clothes are moved upward based on the centrifugal force generated at that time, and the clothes are easily stirred.

The second means of the present invention is such that after the washing, rinsing and dehydration steps are completed,
Rotate the pulsator and apply centrifugal force to the clothes. The centrifugal force pushes the clothes up above the dehydration tank. This causes the clothes to be agitated and dried by the blowing means, but the clothes repelled by the centrifugal force move upward along the dehydration tank wall surface and reach the bottom of the fluid balancer. At this time, if the bottom surface of the fluid balancer is projected from the dehydration tank as in the conventional case, the clothing splashed on the bottom surface of the projected fluid balancer is prevented from further splashing, and efficient stirring cannot be performed. By providing a tapered slope from the inner diameter of the fluid balancer downward to the inner diameter of the dehydration tank, the fluid balancer protruding into the dehydration tank can be smoothly stirred without hindering the movement of the clothes, and The clothes are scattered to the outside of the dehydration tub and fall inward to promote the stirring of the clothes.

According to the third means of the present invention, when the washing, rinsing and spin-drying steps are completed, the pulsator is rotated by the power of the drive motor to apply a centrifugal force to the clothes. Due to this centrifugal force, the clothes tend to be splashed above the dehydration tank, and at this time, an elastic body projecting inward of the dehydration tank is provided on the pulsator, which is encouraged by the repulsive force of the elastic body deflected by the inertia of the clothes. Moreover, the clothes can be splashed higher and effective stirring can be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 15 denotes a water tank suspended from a main body 16 by a plurality of suspensions 17 in a semi-constrained manner. Further, the water tank 15 has a dehydration tank 21 axially supported by a dehydration shaft 18, appropriately provided with water passage holes 19 and a fluid balancer 20, and having an inner diameter gradually widening upward in a tapered shape. Further, 22 is the dehydration shaft 18
Is a bearing that supports. Further, 23 is a dehydration shaft 18
The washing shaft is supported by a metal bearing 24 inside. The washing shaft 23 is provided with a pulsator 26 having an inclined surface 25 inside the dehydration tub 21, and the drive motor 2 is provided at the other end.
7 are connected. Further, 28 is a blower means fixed to the top surface of the water tank 15.

The operation of the above configuration will be described. When the washing, rinsing, and dehydrating processes are completed, the pulsator 26 is rotated by the power of the drive motor 27, and centrifugal force is applied to the clothes. Although the clothes tend to be splashed out by this centrifugal force, they are splashed above the dehydration tub 21 along the inclined surface 25 of the pulsator 26. As a result, the clothes are agitated and uniformly dried by the blowing means, but the clothes repelled by the centrifugal force move upward while coming into contact with the wall surface of the dehydration tank 21. At this time, by gradually widening the inner diameter of the dehydration tub 21 in the upward direction, the contact resistance between the clothes and the wall surface of the dehydration tub 21 can be reduced and the water can be repelled higher. Further, by rotating the dehydration tank 21 at a high speed, it is possible to easily stir the clothes upward by the centrifugal force generated at that time.

Next, a second embodiment of the present invention will be described with reference to FIG. In this embodiment, the entire structure of the fully automatic washing machine is the same as that shown in FIG. 1, and therefore its explanation is omitted, and the difference will be mainly described below.

Fluid balancer 2 protruding into the dehydration tank 21
The bottom surface of the fluid balancer 20 has a tapered slope 29 whose inner diameter decreases downward from the inner diameter of the fluid balancer 20.

The operation of the above configuration will be described. When the washing, rinsing, and dehydrating processes are completed, the pulsator 26 is rotated by the power of the drive motor 27, and centrifugal force is applied to the clothes. The centrifugal force pushes the clothes up above the dehydration tank 21. This causes the clothes to be agitated and dried by the blowing means 28, but the clothes repelled by the centrifugal force move upward along the wall surface of the dehydration tank 21 and reach the bottom of the fluid balancer 20. At this time, by providing a tapered slope 29 having an inner diameter that becomes smaller in the upward direction on the bottom surface of the fluid balancer 20, it is possible to smoothly stir without disturbing the movement of the clothes.

Next, a third embodiment of the present invention will be described with reference to FIG. In this embodiment, the entire structure of the fully automatic washing machine is the same as that shown in FIG. 1, and therefore its explanation is omitted, and the difference will be mainly described below.

The pulsator 26 is provided with an elastic body 30 projecting into the dehydration tank 21. When the washing, rinsing, and dehydrating processes are completed, the pulsator 26 is rotated by the power of the drive motor 27, and centrifugal force is applied to the clothes. Due to this centrifugal force, the clothes tend to be splashed above the dehydration tub 21, and at this time, the repulsive force of the elastic body 30 that is deflected by the inertia of the clothes at this time encourages the clothes to rise even higher and effective stirring can be performed.

[0022]

As described above, according to the first means of the present invention, the inner diameter of the dewatering tank spreads upward in a taper shape, so that the centrifugal force in the dewatering process horizontally applies clothes to the dewatering tank wall surface. However, due to the inclination, part of the reaction force of the collision is released in the other direction, so that the contact resistance between the clothes and the wall surface of the dehydration tank can be reduced, and the clothes can be prevented from being damaged. Further, by rotating the dehydration tank at a high speed, for the same reason as described above, it is possible to move the clothes upward based on the centrifugal force generated at that time, facilitate stirring, and reduce the damage to the clothes. .

The second means of the present invention provides a tapered slope from the inner diameter of the fluid balancer downward to the inner diameter of the dewatering tank by projecting below the fluid balancer protruding into the dewatering tank. The clothes can be smoothly stirred without hindering the movement, and the clothes can be scattered to the outside of the dehydration tank and dropped inward to promote the stirring of the clothes.

The third means of the present invention is to provide an elastic body projecting inwardly of the dehydration tank on the pulsator, and in the dehydration process,
The garment is encouraged by the repulsive force of the elastic body that is deflected by the inertia, so that the garment can be splashed higher and effectively stirred.

As is clear from the above, according to the present invention, by effectively stirring the clothes, the warm air can be uniformly blown to the clothes and the clothes can be efficiently dried.
