Description

[Detailed Description of the Invention] The present invention relates to a clothes dryer, in which hot air is guided into the rotating drum from hot air intake holes provided in the drum support plate in order to dry the clothes in the rotating drum. To provide a highly safe clothes dryer with a simple configuration by using a filter to prevent cotton waste from clothes inside from accumulating in a heater case due to backflow or the like.

In a conventional clothes dryer, a hot air intake hole is provided in a drum support plate that rotatably supports a rotating drum, and this hot air intake hole is communicated with the inside of the rotating drum.
A highly heat-resistant filter, located on the inner surface of the rotating drum and integrally molded into a resin frame, was fixed with screws or rivets, facing the hot air intake holes.
However, since the filter is made of a resin frame, the unit cost of the parts is high, and since it is fixed with screws or rivets, the number of parts and installation man-hours are large.Moreover, clothing may come into contact with the resin frame of the filter or the heads of the screws, causing damage to the clothing and There was a drawback that the generation of dust increased and the cotton dust that adhered to the filter also adhered to clothing.

The present invention solves the above-mentioned conventional problems, and embodiments thereof will be described below with reference to the accompanying drawings.
In the figure, reference numeral 1 denotes a device main body, and a rotary drum is supported for four rotations by a drum support plate 2 and a fan casing 3 fixed inside. A drive motor 5 rotates the rotary drum 4 and the fan 8 in the fan casing 3 via a V-belt 6 and a fan belt 7, respectively. Reference numeral 9 denotes a clothes inlet of the rotary drum 4, and a door 10 covering this opening can be freely opened and closed, and a door 10 is fixed to the front surface of the main body 1 of the apparatus. 11
is an in-drum filter 11 provided on the rear surface of the rotating drum 4.

Reference numeral 12 denotes a heater case provided at the front inside the device main body 1, and a heater 13 constituting a heat source is provided inside the heater case.

The drum support plate 2 is fixed to the inner surface of the device main body 1, and is attached to the upper opening 1 of the heater case 12.
4 communicates with a large number of hot air intake holes 15 formed in the drum support plate 2, and these hot air intake holes 15 communicate with the inside of the rotating drum 4. A packing 16 is provided on the end face of the upper opening 14 of the heater case 12, and between this packing 16 and the outer periphery of the hot air intake hole 15 of the drum support plate 2 provided opposite to the upper opening 14, It holds the filter 17.

Reference numeral 18 indicates an air outlet provided at the lower end side of the heater case 12, 19 indicates clothes to be dried, 20 indicates an insulator holding the heater 13, and 21 and 22 indicate the heater case 12, the main body 1, and the drum support plate 2. An insulating spacer 23 that insulates between the two is a bearing that rotatably supports the rotating drum 4.

In the above configuration, when the switch provided in the device body 1 is turned on, the drive motor 5 and the heater 13
The rotary drum 4 and the fan 8 are rotated via the V-belt 6 and the fan belt 7. Air sucked in from outside the device main body 1 by the rotation of the fan 8 passes through the air outlet 18 of the heater case 12 and is heated by the heater 13 to become hot air. This hot air passes through the filter 17 and the hot air intake hole 15 of the drum support plate 2 from the upper opening 14, and then passes through the rotating drum 4.
Go inside and dry the clothes 19. The air containing moisture generated by this drying is passed from the filter 11 in the drum at the rear of the rotating drum 4 to the fan casing 3.
It passes through and is discharged to the outside of the device main body 1.

Here, the clothes 19 inside the rotating drum 4 generate a lot of cotton dust due to contact between the clothes and the surface of the drum support plate 2 . However,
By providing a filter 17 between the end surface of the upper opening 14 of the heater case 12 and the inside of the hot air intake hole 15 of the drum support plate 2, it is possible to prevent the cotton dust from flowing back into the heater case 12. In addition, since the filter 17 is disposed between the heater case 12 and the drum support plate 2 as described above, it can be constructed from a pressed product such as a wire mesh filter, and the unit cost of the parts is low.
By positioning it between the heater case 12 and the drum support plate 2, the number of parts and the number of installation steps can be greatly reduced.

Furthermore, if the numerous hot air intake holes 15 provided in the drum support plate 2 are formed into a burring shape that protrudes outward from the rotating drum 4, fabric damage caused by contact between the end face of the intake holes and clothing can be eliminated, and the generation of cotton waste can be prevented. You can do less.

As described above, the present invention provides a filter between the end face of the opening corresponding to the hot air outlet of the heater case housing the heat source and the inside of the numerous hot air intake holes formed in the drum support plate so as to communicate with the interior of the rotating drum. By positioning and holding the cotton dust in place, the filter can reliably capture the cotton dust that tends to flow back into the heater case from inside the rotating drum, and prevents the drying material from hitting the filter itself. In addition to preventing dust from re-adhering, the filter mounting part does not protrude inside the drum, which prevents damage to the dried material.Furthermore, a filter with a simple structure, such as a wire mesh filter, can be used. It has great effects such as requiring no effort to install it.
