Abstract

PURPOSE:To eliminate clap sounds of a chuck, button, etc., in stirring clothing to be dried, by providing a bag for receiving said clothing inside a drum. CONSTITUTION:A dehydrated clothing 22 is received in a bag 25 and current is supplied to a motor 18 and heater 13. A drum 7 and a double sided fan 16 are rotated respectively with low and high speed. Air from a circulating path 10 is heated by a heater 13 in a L-shaped duct 14, enters as high temperature air the drum 7 from a hot air inlet 9 of a drum support plate 5, passes through the bag 25, evaporates water content included in the clothing 22, causes waste cloth to be caught by a filter and is sucked in the double-sided fan 16 in a fan casing 11 from a hot air outlet 8. Condeced water cooled here by the external air is drained from a drain port 15 of the circulating path 10. The clothing 22 in the bag 25 is rotated in the bag 25 rotated integrally with the drum 7 through a pulley and belt 24 by the motor 18 so that potential energy generated by the clothing 22 scraped up and dropped is absorbed by the bag 25 made of a soft material to restrain clap sounds of buttons or the like.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a clothes dryer, and in particular, when stirring drying materials,
Related to eliminating the sound of tapping zippers, buttons, etc.

[Conventional technology]

Conventional dryers rotate a drum that serves as a dryer, and the clothes stored in the drum are also rotated and agitated as the drum rotates. This rotation of clothing.

Dry the clothes by stirring so that the hot air evenly hits the clothes. However, when clothes with zippers or buttons are placed in the dryer to dry, the rotation of the machine lifts the clothes and as they fall, the zippers or buttons slam against the drum made of steel or plastic, producing a clanking sound. No consideration was given to this impact noise. In addition, some cushioning materials are applied only to the inner surface of the outer periphery of the drum to reduce impact noise, but the side surfaces of the drum are not taken into account, and the full effect is not achieved.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, zippers and buttons attached to clothing are picked up by rotation, and when they fall, they slam against the inner surface of a drum made of hard material, producing a clanking sound. When drying clothes with zippers or buttons, the noise level increases by about 20 dB, which is a problem.

The object of the present invention is to use this zipper, a clicker with a button,
The purpose is to eliminate the clicking sound.

[Means to solve the problem]

The purpose of the present invention is to provide a bag with good air permeability and flexibility between the inner surface of the drum and the clothing, and to absorb the impact force of dropping zippers and buttons attached to the clothing, thereby eliminating clicking sounds. is achieved.

[Effect]

The bag of the present invention is attached to the inner surface of the drum and configured to rotate together with the drum, which is the same principle as when two conventional drums are stacked, so the clothes inside the bag can be freely rotated and agitated. Therefore, there will be no problems such as the bag becoming twisted or not being able to dry.

In addition, the ventilation holes in the bag are small enough to prevent zippers, buttons, etc. from getting caught, so there is no risk of clothing getting caught.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. A back cover 2 is fixed to the rear surface of a machine frame 1 made of gold R.

Clothes entrance/exit formed on the front of the machine frame 1 3. A door 4 for opening and closing the entrance/exit 3 is located at the front of the machine frame 1, and includes a metal annular drum support plate 5 fixed to the machine frame 1 and a rear bearing 6 disposed at the rear of the machine frame 1. A drum 7 serving as a drying chamber is rotatably supported. The drum 7 has a hot air outlet 8 formed of a large number of holes on its rear surface. Drum support plate 5
To the hot air population 9 formed on the lower side of the fan casing 1
A circulation path 1o is formed which communicates with the first vent 12. A honeycomb-shaped heater 13 made of a positive temperature coefficient thermistor is provided opposite the hot air inlet 9, and is housed in an L-shaped duct 14 fixed to the drum support plate 5. Heat exchange type double-sided fan 16 disposed across the fan casing 11
is rotatably supported on a support shaft 17 via metal.

A motor 18 disposed in the upper part of the machine frame 1 rotates the drum 7 using pulleys including an idler pulley and a belt 24, and the double-sided fan 16 is also rotated by the pulley belt. A filter 19 is attached from inside so as to cover the hot air outlet on the rear surface of the drum 7. A cooling air inlet 20 is formed in the center of the back cover 2, and a cooling air outlet 21 is formed in the outer periphery. A temperature sensor 23 that detects changes in the state of the air inside the drum is installed in the fan casing facing the hot air outlet 8 provided on the rear surface of the drum. Further, a net-like bag 25 is attached to the inner surface of the drum 7 at a plurality of locations using removable Velcro tapes 26. The lid 27 of this bag 25 is made of rope and has Velcro tape 26.
The bag 25 can be removed.

The operation will be explained below. When driving, first open the door 4, remove the lid 27 of the bag 25, and place the dehydrated clothes 22 into the bag 2.
When the power is turned on (not shown), the electric motor 1
Air from the circulation path 10 in which the drum 7 and the heater 13 are energized to rotate at a low speed and a double-sided fan 16 at a high speed is heated by the heater 13 in the L-shaped duct 14 and is transferred to the drum 11 support plate 5 as high-temperature dry air. The hot air enters the drum 7 from the population 9, passes through the bag 25 made of net, and is evenly applied to the clothes rotating inside the bag 25, evaporating the moisture contained in the clothes 22, becoming high temperature, and filtering the filter 19. After the cloth waste is collected, it is sucked into the double-sided fan 16 in the fan casing 11 from the hot air outlet 8 of the drum 7. Here, the air outside the machine is cooled to below the dew point temperature, and the double-sided fan 1
Condensed water is generated on the side of the circulation air passage 6, and the condensed water is discharged from the drain port 15 of the circulation passage 10.

The clothes 22 in the bag 25 are freely rotated in the bag 25, which rotates integrally with the drum 7, by a motor 18, which is a driving source, via a pulley and a belt 24. The bag 25 made of a flexible material absorbs the potential energy when the clothing 22 is picked up and falls, thereby suppressing the clanking sound.

FIG. 2 shows the bag 25 and the lid 27.

In FIG. 3, the same effect is obtained by making the bag 25 and lid 27 openable and closable with a zipper 28.

In FIG. 4, the same effect can be obtained by attaching the lid 27 to the inner door 29 with removable Velcro 26.

FIG. 5 shows a rotary shaft 31 supported by an inner door 29, and a lid 27 attached to a lid fixing plate 30 so as to be freely rotatable and removable. You can get the same effect with this.

〔Effect of the invention〕

According to the present invention, even when drying clothes with zippers or buttons, the bag's flexibility absorbs and eliminates the banging noise of the zippers and buttons when it rotates or falls, compared to when only the drum is used. It becomes possible to suppress the tapping sound of 65 dB to 45 dB.
