Description

[Detailed Description of the Invention] The present invention particularly relates to a synthetic resin drum whose portion that is exposed to hot air is made of a metal plate.

Drums used in clothes dryers include those made of iron plates and those made of synthetic resin, but drums made of iron plates are very time-consuming to process and assemble, and drums made of synthetic resin are sensitive to high temperatures. There are drawbacks.

The present invention incorporates the advantages of both to facilitate assembly and improve heat resistance.

To explain based on the figures below, 1 is a clothes dryer having a door 2 for loading clothes on the front, a drum 3 for drying clothes,
A motor 4 that drives the drum, a blower 5 and a heater 6
Built-in.

The drum 3 includes a bottomed cylindrical portion 7 made of synthetic resin with one end open, and a metal end cover 8 that closes the open end of the bottomed cylindrical portion.

The bottomed cylindrical portion 7 has a baffle 9 protruding from its inner peripheral surface for lifting up clothes during rotation, and a hot air outlet 10 at the center of one end surface. The end cover 8 has a clothing inlet 11 formed in the center, a large number of hot air flow holes 12, etc., formed around the clothing inlet, and an annular bent edge 13 formed on the periphery. are doing.

This end cover 8 is applied to the open end of the bottomed cylindrical portion 7,
In addition, the screws 14 inserted from the end cover 8 side are fixed by screwing into the end surfaces of the baffles 9 formed in the cylindrical portion, and the annular shape of the end cover The bent edge 13 is fitted into the opening edge of the cylindrical portion 7 from the outside, and this annular fold is attached to the hook portions 15 integrally formed on the outer periphery of the cylindrical portion 7 at appropriate intervals. By locking the curved edge 13, deformation of the cylindrical portion 7 is prevented.

This locking is performed between the outer circumferential surface of the cylindrical portion 7 and the hook portion 15...
This is done by inserting an annular bent edge between...

The drum 3 is formed in this manner, and the hot air outlet 10 of this drum is rotatably supported by the opening edge of the blower case 16 surrounding the blower 5, and the clothes input port 11 is connected to the heater. It is supported by the opening edge of the mounting plate 17.

18 is a filter detachably attached to the hot air outlet 10.

In the above configuration, when the heater 6 is energized and the drum 3 and blower 5 are rotated by the motor 4, air is taken in from the air intake port 19 formed on the back of the main body, heated by the heater 6, and turned into hot air. After that, the population of hot air flow was 12...
- enters the drum 3 through the drum, and after drying the clothes in the drum, is discharged to the outside of the main body by the blower 5.

That is, the drum 3 is installed in the main body so that the hot air flow 12 is on the windward side and the hot air outlet 10 is on the leeward side.

As described above, in this case, since the bottomed cylindrical portion 7 of the drum is formed of synthetic resin, there is no need for welding work, etc. that is required when assembling a metal plate curved into a cylindrical shape, and the assembly is easy and mass production is possible. rich in

Also, there is a hot air flow 12 around the clothing input port 11...
In a drum with perforations, this hot air flow area is exposed to high temperatures, so a drum made of synthetic resin up to this area would have poor durability.
Since the end cover 8 having the holes therein is made of metal, it has great heat resistance and can extend its life.

Further, the end cover 8 is screwed to the end surface of a baffle 9 formed in the bottomed cylindrical portion, and has a plurality of hook portions 15 with an annular bent edge 13 formed on the outer peripheral surface of the bottomed cylindrical portion. . . , at appropriate intervals, even if the bottomed cylindrical portion 7 made of synthetic resin tries to deform due to heat, it is prevented by the end cap 8 and will not deform even after long-term use.

Note that the hook portions 15 may be formed into continuous annular grooves without being formed at appropriate intervals, but in this case, the annular protrusion for forming the annular grooves may be formed on the side of the molding die. Since it becomes necessary to form the hook portions 15 at appropriate intervals and the mold becomes weak, as in the present proposal, a plurality of hook portions 15 are formed at appropriate intervals.
・It is better to form
