Description

Detailed Description of the Invention The present invention uses the rotation of a fan to draw in air from the IF surface of the main body of the device and cause hot air heated by a heater to flow into a drum serving as a storage space for items to be dried, and to exchange heat with the items to be dried. The present invention relates to a clothes dryer that exhausts air, and particularly relates to an improvement in the mounting structure of an air intake filter that forms an air intake path that passes through a heater by 1 m.

For example, in the clothes dryer shown in FIG.
With a lid 15 that can be opened and closed to cover the clothing input port 16, the circular helmet protrusion 19 of the lid 15 is brought into contact with the backing 18 provided on the circular flange 17 forming the front clothing input port 16 of the device main body 1 to seal it. A number of intake ports 30 are formed in the lower part of the lid 15 facing the heater 10, and a removable intake filter 31 is provided on the inside, and a rib 32 whose both ends are connected to the circular protrusion 19 is provided inside the lid 16. A lid backing 33 was fixed to the rib 32 and brought into contact with the curved surface of the device main body 1 to form an intake path. If an abnormal condition occurs where the fan stops blowing air, the heater 10 will overheat and the clothes will continue to be agitated, so the hot air will flow back from the air outlet due to the air generated by the agitation of the clothes. , intake filter 31 and button 15
could be transformed.

The present invention solves the above-mentioned conventional drawbacks by improving the mounting structure of the intake filter attached to the lid, and aims to provide a clothes dryer of unprecedented high quality.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, a drum 2 is rotatably supported within a device body 1, a fan 4 that rotates within a fan case 3 is provided behind the drum 2, and a drum pulley 6 and a motor pulley 7 are connected to the rotation shaft of a drive motor 5. Fixed this goo IJ-6
, 7 by the V-belt 8 and fan belt 9,
The drum 2 and fan 4 rotate. Reference numeral 1o denotes a self-heating heater having positive temperature characteristics, which is appropriately fixed to the heater case 12 between a drum support plate 11 that rotatably supports the drum 2 and the front surface of the main body 1 of the device. A bearing 13 for rotationally supporting the drum 2 is provided on the outer periphery of the drum support plate 11, and a large number of ventilation holes 14 are provided behind the heater 1o to allow hot air to flow into the drum 2.

Reference numeral 16 denotes a lid that can be opened and closed to cover the clothes input port 16, and a circular flange 1 that forms the front clothes input port 16 of the device body 1.
The circular protrusion 19 of the lid 16 is attached to the backing 18 provided at 7.
A suction port 2o is formed in the lower part of the lid 15 facing the heater 1o, and the suction port 2o
A removable intake filter 21 fitted from the outside of the lid 16 is formed of a synthetic resin having better heat resistance than the lid 16. M of heater 1o? An air outlet 25 having a large number of intake slits 24 is fixed to the T side of the main body 10ir, which corresponds to the J side. The intake filter 21 is provided with a rib 22, and a lid backing 23 is provided on the rib 22.
is fixed, and the lid backing 23 is brought into contact with the outer periphery of the air outlet 25 to form an air intake path.

The operation of the above configuration will be explained below.

As the fan 4 rotates, the intake air is transferred to the rib 22 of the intake filter 21 attached to the intake port 2o of the lid 15.
Passes through the intake path sealed with the lid backing 23,
Air is taken in from the intake slit 24 of the ventilation port 26, and
The hot air heated by o enters the drum 2 through the ventilation holes 14 of the drum support plate 110, exchanges heat with the clothes, and
It passes through a filter 28 that is removably provided on the rear surface, flows into the fan case 3, and is discharged by the fan 4 into the exhaust guide 29.
The entire air is exhausted to the outside of the device main body 1.

In this way, according to this embodiment, it is sufficient to select a material for the lid that is a synthetic resin that has good moldability and does not cause any appearance problems such as moss after molding. There is also an advantage in terms of cost since no materials are required.

On the other hand, if an abnormal condition occurs in which the fan belt 9 breaks or comes off during operation, the heater 1o is overheated because the air blowing is stopped. On the other hand, since the clothes in the drum 2 continue to be agitated, the air generated by the agitation of the clothes enters the heater 10 through the ventilation holes 14 of the drum support plate 11, and the hot air, which has become superheated and reaches a high temperature, passes through the intake slit 24 to the lid 15. Conventionally, a lid was used to cause the flow to flow in the opposite direction to normal. A lid to prevent deformation of the intake filter. Both the intake filter had to be made of heat-resistant synthetic resin, making it extremely expensive.

Alternatively, the cost was high because a thermostat was installed between the heater 1o and the intake slit 24 to detect high temperature and cut off the power supply circuit, but by forming the intake path with the intake filter 21 as in the present invention, By forming only this intake filter 21 with a heat-resistant synthetic resin, it is possible to prevent deformation in the event of an abnormality, and since only the intake filter 21, which is a small part, is made of a high-grade heat-resistant synthetic resin, costs can be reduced. can also be reduced.

The air intake filter 2 can be attached and detached from the outside of the lid 16.
1 is installed, the intake filter 21 can be handled from the product side, and maintenance such as cleaning of the intake filter 21 is greatly improved, operation is easy, and usability can be greatly improved. Further, since the intake filter 21 has a flange shape around the periphery by the ribs 22, it is possible to prevent clothes from welding to the dust suction part and getting dirty when taking them in or out.

As described below, the present invention has extremely practical effects.
