Description

[Detailed Description of the Invention] The present invention relates to a rotary drum type clothes dryer, and particularly relates to a support structure on the rear side of the rotary drum.

Conventionally, in this type of clothes dryer, as shown in FIG. 3, a drum shaft 32 is fixed to the center of the rear end surface of a rotating drum 31, and a bearing 34 containing lubricant etc. is installed in the rear cover 33. By inserting the drum shaft 32 into the bearing 34, the rotating drum 3
1 was supported rotatably, but this structure required a large number of parts such as the drum shaft 32, bearing 34, and their attachment parts, and the assembly work was also complicated, making it very difficult from the viewpoint of workability and cost. It was bad for me.

This proposal was made in view of these points,
The embodiment of the present invention shown in FIGS. 1 and 2 will be described in detail below. Reference numeral 1 denotes a cabinet having an opening 2 on the front, and a door 3 for opening and closing the opening 2.
It has a central location. Reference numeral 4 denotes a front cover fixed to the inner surface of the cabinet 1 so as to be positioned around the opening 2. A bearing material 5 is provided on the inner peripheral edge of the front cover 4, and a sealing felt 6 is provided on the outer peripheral edge of the front cover. An exhaust port 7 is provided, and an exhaust passage 8 is formed between it and the front end surface of a rotating drum, which will be described later. Reference numeral 9 denotes a rotary drum having an input port 10 on the front side and an air discharge part 11 consisting of a large number of small holes on the outer circumference thereof, and the front side of the drum is rotatably supported on a bearing material 5. (Rear end surface) 12 has an air intake part (ventilation port) 1 having a central part bulging forward to form a receiving part 13 and a large number of small holes on the outer periphery of the receiving part 13.
form 4. Reference numeral 15 denotes a rear cover which is fixed within the cabinet 1 and has a sealing felt 16 on its outer peripheral edge to form an intake passage (ventilation passage) 17 between it and the drum rear plate 12, and has an intake port 18 at a proper location. Reference numeral 19 denotes a protrusion formed by bulging the center part of the rear cover 15 forward, and a protrusion 19 that is formed by bulging the center part of the rear cover 15,
3 through the sliding contact member 20, the rear side of the rotary drum 9 is rotatably supported.
Incidentally, as the sliding contact member 20, for example, an oil-impregnated member is used. Reference numeral 21 denotes an intake duct that communicates with the intake port 18 and has a heater 22 installed therein. Reference numeral 23 denotes an electric motor installed on the inner bottom surface of the cabinet 1. A fan 24 is attached to one end of the rotating shaft, and a pulley 2 is attached to the other end.
5. It is linked to the rotating drum 9 via the belt 26. 27 is a fan case whose suction side is connected to the exhaust port 7 and whose discharge side is connected to the exhaust duct 28;
A thread waste filter 29 is detachably installed on the suction side. 30 indicates a lid that closes the filter outlet.

In the above configuration, when clothes are put into the rotating drum 9 and the electric motor 21 is driven to rotate, the rotating drum 9 starts rotating and loosens the clothes by the rotation.
The fan 24 also starts rotating and sucks air into the intake duct 21. Then, the sucked air is heated by the heater 22 in the intake duct 21, turns into hot air, enters the rotating drum 9 through the intake port 18, intake passage 17, and air intake part 14, and dries by contacting the clothes. The air then passes through the air exhaust section 11, the exhaust passage 8, the exhaust port 7, the fan case 27, and is discharged from the exhaust duct 28 to the outside of the machine.
In this way, the clothes drying operation is performed.

In the above embodiment, the central part of the drum rear plate 12 and the central part of the rear cover 15 are respectively bulged rearward to form a protrusion on the rotating drum 9 side.
A receiving portion may be formed at 5.

As described above, according to the configuration of the present invention, it is possible to reduce the number of parts for supporting the rear side of the rotating drum, simplify the assembly work, and provide a product that is good in terms of workability and cost. can.
