BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic washing and drying machine used in ordinary households.

[0002]

2. Description of the Related Art The construction of a new fully automatic washing and drying machine is shown in FIG.
Description will be made based on 0.

[0003] 1 is a housing of a fully automatic washing and drying machine, and 2 is a receiving cylinder. Reference numeral 3 denotes a suspension mechanism for suspending and supporting the receiving cylinder 2 from the casing 1. Reference numeral 4 denotes a washing / dehydrating shaft having a hollow biaxial structure, 5 denotes a clutch for switching transmission of rotational force to the washing / dehydrating shaft during washing or dehydrating, 6 denotes a washing / dehydrating tub, and 7 denotes a washing / dehydrating tub. It is a fluid balancer provided in. Reference numeral 8 denotes a motor provided at the bottom of the receiving tube 2, and 9 denotes a pulsator provided at the center bottom of the washing and dewatering tub, which is provided with an inclined surface on its outer periphery and has a pan-shaped shape. . Numeral 10 denotes rib-shaped wings formed radially from the central portion of the pulsator to the outer periphery through the inclined surface of the outer peripheral portion. 11 is a drain cock, 12 is hot air blowing means, 13 is a substantially horizontally provided telescopic tube for sending hot air into the washing and dewatering tub 6, and 14 is a heat exchange unit. is there.

The operation of the thus-configured fully automatic washing / drying machine will be described below.

For washing, clothes, water and detergent are put into the washing and dewatering tub 6, the clutch of the transmission mechanism 5 is set to the washing side, and the power of the motor 8 is transmitted to the pulsator 9 via the washing shaft. As the pulsator 9 rotates, the clothing is caught by the rib-shaped wings 10 of the pulsator 9 and rotated underwater to progress.

[0006] Dehydration is performed after washing and rinsing are completed.
After draining the water in the washing and dewatering tub 6 by opening the drain cock 11, the clutch of the transmission mechanism 5 is switched to the dehydrating side,
The washing and dewatering tub 6 is rotated by the power of the motor 8 through a dewatering shaft, and the water is separated from the laundry by centrifugal force.

In the drying, first, the pulsator 9 is rotated and the clothes adhered to the inner wall of the washing and dewatering tub 6 are peeled off by the centrifugal force at the time of dehydration, and are disturbed up and down in the washing and dewatering tub 6. In this state, warm air is blown from the hot air blowing means 12 into the washing and dewatering tub 6 through the telescopic tube 13. By this warm air, we take moisture of thing to be dried,
Thereafter, dehumidification is performed while passing through the heat exchange unit 14, and the airflow is
The drying proceeds by returning to the hot air generating means 12 again.

[0008]

When the telescopic tube 13 through which warm air passes is provided in a substantially horizontal direction as shown in the conventional configuration, it is pulled in one horizontal direction above the washing and dewatering tub 6. Therefore, the vibration of the swinging motion of the washing and dewatering tub 6 due to the high-speed rotation during the dehydration is not uniformly transmitted to the housing, and causes a distorted vibration as a whole. In some cases, due to the distorted vibration, there is a problem that the spinning of the washing and spinning tub 6 itself does not rise.

Further, since the inside of the telescopic tube 13 is hollow, a lot of bubbles generated at the time of washing reach the hot air generator 12 through the inside thereof, causing various inconveniences. There were also issues.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a fully automatic washing and drying machine capable of efficiently performing washing and drying while reducing vibration during a spin-drying operation.

It is another object of the present invention to provide a fully automatic washing / drying machine having a structure in which bubbles during washing do not reach the hot air device.

[0012]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention relates to a fully automatic washing and drying machine, which comprises a vertically extending telescopic tube for communicating a washing and dewatering tub from a receiving tube which is a hot air path. It is connected to each from the direction,
With this configuration, the washing and dewatering tub is not pulled in one direction, so that the vibration of the washing and dewatering tub is transmitted to the housing almost uniformly, and the vibration during operation can be reduced as a whole.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION
A housing that supports the receiving cylinder with a plurality of suspensions,

It is a fully automatic washing and drying machine that is connected by doing. In this configuration, since the bellows-shaped telescopic tube is in a substantially vertical state, even if the washing and dewatering tub swings when rotating at high speed during dehydration, it is not pulled in one horizontal direction, Vibration occurs in a substantially natural state, and the vibration is transmitted uniformly to the housing, thereby reducing the vibration as a whole.

[0014] The second aspect of the present invention is the first aspect.
In addition to the invention described above, a bellows-shaped telescopic tube is provided with a flexible vibration-absorbing portion at at least one end, so that vibration can be absorbed more flexibly during the swinging movement of the washing and dewatering tub. As a result, the transmission of vibration to the housing is reduced, and the washing machine is a fully automatic washing and drying machine with reduced vibration.

The third aspect of the present invention is the first aspect of the present invention.
In addition to the described invention, a hollow passage formed by the end of the bellows-shaped telescopic tube is provided along the inner surface of the washing and dewatering tub up to near the center of the partition plate, and the outlet of the passage is provided at the outlet of the passage. Since the guide for guiding air is provided on the side of the washing and dewatering tub, the warm air efficiently hits the object to be dried at the time of drying, and efficient drying is achieved as a whole.

The fourth aspect of the present invention is the first aspect.
In addition to the above-mentioned invention, the end of the bellows-shaped telescopic tube is installed tangentially to the upper surface of the partition plate so as to blow air along the outer circumferential direction of the washing dewatering tub. Because of this, warm air is swirled inside the washing and dewatering tub, so that the hot air hits the entire material to be dried. As a result, drying is promoted, and high-speed drying can be realized.

The fifth aspect of the present invention is the first aspect of the present invention.
In addition to the described invention, the end of the bellows-shaped telescopic tube is divided into a plurality of tubes, and each of the tubes can be blown against the upper surface of the partition plate along the outer peripheral direction of the washing dewatering tub. As it is installed inclined in the tangential direction as described above, since the hot air is in a violent swirl inside the washing and dewatering tub, it hits the whole dried material well and the drying is promoted, As a result, the object to be dried can be dried at a high speed.

The invention according to claim 6 of the present invention is the invention according to claim 1.
In addition to the described invention, the inside of the bellows-shaped telescopic tube opens for the flow of air in the direction of the washing and dewatering tub,
Since a valve is provided that does not open to the flow of air from the washing and dewatering tub side in the opposite direction, bubbles generated during washing pass through the inside of the bellows-shaped telescopic tube and heat on the housing side. Prevents entry into the wind generator.
