Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clothes dryer that introduces hot air into a rotating drum, and by introducing cold air into a drum support plate that forms a drum input opening, it is possible to dry clothes easily when loading and unloading items to be dried. The purpose is to prevent burns.

A conventional clothes dryer is as shown in FIG. 1, with a body 101 being the main body of the clothes dryer, the front side of which is covered with a front body 103 having an input port 102 for loading and unloading clothes. , the rear side is covered with a back plate 104. Also, the front body 103
A lid 105 for opening and closing the input port 102 is attached to the lid 105, and an air intake port 106 is provided on the lid 105.

Reference numeral 107 is a substantially cylindrical rotating drum having an outlet 108 for ventilation on the rear wall, which rotates and agitates the clothes. A filter cover 110 equipped with a filter 109 is attached to the drum 107 on the outlet 108 side.
The drum shaft 111 is coaxially and removably engaged with a drum shaft 111 fixed to the center of the drum shaft 111.

112 is a motor installed at the bottom of the body 101, which connects the drum 1 through a drum pulley 114 fixed to a motor shaft 113, a motor pulley 115, a drum belt 116, and a fan belt 117.
07, rotational force is transmitted to the fan pulley 118.

119 is a heater 12 attached to the front body 103
A heating furnace is formed by a heater cover having a diameter of 0 and a drum support plate 122 having an intake hole 121. The rotating drum 10 is mounted on the drum support plate 122.
A sealing material 123 that also serves as a seal is fixed to the bearing of the front flange portion of No. 7, and the rotary drum 107 is airtightly and rotatably supported via the sealing material 123.

Reference numerals 124 and 125 denote fan cases, and as a fan 126 rotates, air is sucked in from the intake port 106 of the lid 105, passes through the intake slit 127 of the front body 103, and then passes through the heater 120 to become hot air, which is then heated to support the drum. Intake hole 12 of plate 122
Hot air is introduced into the rotating drum 107 through the rotary drum 107. 128 indicates a cover, and 129 indicates clothing.

Conventionally, when loading and unloading clothing 129 from the input port 102, there is a risk of burns due to contact with position A of the drum support plate 122 near the heater 120, so a cover is made of a material that is highly heat resistant and has poor thermal conductivity. There was a need to install the 128 over the parts that could be touched by hands. Therefore, attaching the cover 128 requires a lot of effort and increases costs, and the cover 128 tends to turn over or come off when it comes into contact with clothing when handling the clothing.

The present invention solves the above conventional problems,
This provides a simple configuration without using a cover.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 5. In the figure, an intake port 203 is provided on a lid 202 provided on the front body 201 so as to be openable and closable, an intake port 205 is provided on the lid 202 of the front body 201 at a position facing the intake air cylinder 204, and a heater 206 is provided on the lid 202 of the front body 201. A frame B is formed on the heater cover 207 fixed to the front body 201, and a plurality of intake ports 210 are provided near the input port 209 of the drum support plate 208. And from the intake port 205 to the frame B,
It constitutes an intake path leading to the intake port 210. 2
11 is a filter, 212 is an intake slit, 21
3 is an intake port.

Therefore, when air is taken in from the fan 126 shown in the first diagram, it passes through the filter 211 from the air intake port 203 of the lid 202, passes through the air intake slit 212, and passes through the heater 206, thereby becoming hot air, which is heated to the drum support plate 208. The first air intake path introduced into the rotating drum 214 from the air intake port 213, the air intake port 205, the frame B, and the air intake port 210 described above.
The air passes through the second intake path via the rotary drum 214 and is introduced into the rotating drum 214.

In the above configuration, when loading and unloading clothing,
Inlet port 209 of drum support plate 208 that comes in contact with hands
The nearby area α does not reach a high temperature because cold air is constantly introduced from the intake port 210, eliminating the risk of burns and eliminating the need for a cover that was conventionally attached to the inlet to prevent burns. . Further, by cooling the high temperature portion x of the heater cover 207 with the cold air from the air intake port 210, the heat resistance and durability of the heater cover 207 made of resin are significantly improved.

As described above, according to the present invention, it is possible to prevent a rise in temperature at the input port portion of the drum support plate by the cooling effect of cold air, and it is possible to prevent burns when taking out clothes. Moreover, the durability of the members near the heat source can be improved by the cooling effect, and a highly safe structure can be provided.
