Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a clothes dryer for drying clothes, etc., and particularly to the structure of a rotating drum.

Conventional technology Drums used in clothes dryers include those made of synthetic resin and those made of iron plates, but synthetic resin drums have the disadvantage of being sensitive to high temperatures, so they cannot be used as a substitute for those made of iron plates. is insufficient. On the other hand, products made of iron plates require the preparation of various processing equipment in order to handle the production of a wide variety of products, which has been particularly demanded in recent years, and at the same time, the processing equipment has to be changed frequently during production, making it difficult to mass-produce. It contained some defects.

Problems to be Solved by the Invention Regarding the assemblability of conventional iron plate drums, there have been the following problems. In other words, we produce a wide variety of products with different sizes, such as welding to assemble metal plates by curving them into a cylindrical shape, and seamer processing to integrate the cylindrical body and end cap, or the cylindrical body and support lid. However, assembly and processing equipment had to be changed frequently, reducing assembly efficiency and increasing capital investment. In view of the above problems, the present invention is easy to assemble and suitable for mass production,
Another object of the present invention is to provide a rotating drum that reduces heat loss and improves drying efficiency.

Means for Solving the Problems In order to achieve the above object, the present invention provides a bottomed cylinder made of synthetic resin, uses this as a base, and screws and fixes a rectangular steel plate to the base to form a cylindrical body, At the same time, an end cover made of a steel plate is screwed and fixed to the open end of the bottomed cylinder, and a support cover made of a steel plate is screwed and fixed to the bottomed part of the other end to constitute a rotating drum. .

The drum can be assembled using ordinary screw tightening operations using the bottomed cylindrical base made of synthetic resin as a base, so there is no need for production equipment such as seaming to match the size of the drum, making it suitable for the production of a wide variety of products. It is possible to provide a drum structure that can be easily assembled anywhere and has extremely high productivity.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In the figure, 1 is a clothes dryer having a door 2 for loading clothes, a rotating drum 3 for drying clothes, and a rotating drum 3 for drying clothes.
It has a built-in motor 4, a blower 6, and a heater 6.

The rotating drum 3 includes a bottomed cylindrical base 7 made of synthetic resin with one end open, a cylindrical body 9 made of a steel plate wrapped around a body 8 of the base 7, and a steel plate closing the open end of the base 7. and a support lid 1 fixed to the bottomed portion of the base 7.
It consists of 1.

The bottomed cylindrical base 7 has a baffle 12 protruding from its inner circumferential surface for picking up clothes during rotation, and the end cover 1o has one end of the rotating drum 3 rotatably supported in the center. A sliding support portion 13 is formed, and an annular bent edge 14 is bent at the periphery.

The cylindrical body part 9 has a rectangular shape made of a steel plate, and is fixed to the base part 7 by wrapping it around the cylindrical part of the base part 7 and passing through the overlapping part of each rectangular end with a screw 16 inserted from the cylindrical body part 9. ing. On the other hand, the end cover 10 is applied to the open end of the bottomed cylindrical base 7, and by screwing the screw 16 inserted from the end cover 10 side into the boss portion 17 formed on the end surface of the base 7, One end of the cylindrical body 9 is pressed and fixed all around so that it is sandwiched between the annular bent edge 14 of the end cap 10 and the base 7.

Further, on the bottom side of the bottomed cylindrical base 7, an annular bent edge 18 is bent at the periphery, and a support lid 11 with a bearing 19 for rotationally supporting a rotating drum fixed in the center is attached to the support lid 11 side. The other end of the cylindrical body 9 is fixed to the base 7 with a screw 20 inserted from the support lid 11.
Press and fix the entire circumference so that the scissors fit between the two. This prevents deformation of the cylindrical portion. The body part 8 is provided with a plurality of ribs 27, and when the cylindrical body part 9 is attached to the base part 7, a plurality of compartments 2 are formed between the body part 8 and the cylindrical body part 9.
8 is formed. The rotary drum 3 is formed like this, and the heat flow port 21 to the rotary drum 3 is provided on the drum front plate 22 that supports the sliding support part 13 of the end cover 10 of the rotary drum 3. A heater 6 is installed on the drum front plate 22.
A heater mounting plate 23 housing the rotary drum 3 is fixed thereto, and a blower case 24 is arranged behind the rotating drum 3. 26
is a filter detachably attached to the hot air outlet 26 of the rotating drum 3.

In the above configuration, the heater 6 is energized and the motor 3
When the rotating drum 3 and the blower 6 are rotated, air is taken in from the air intake port 27, heated by the heater 6, becomes hot air, passes through the entire hot air flow 21, enters the rotating drum 3, and removes the clothes inside the rotating drum 3. After drying, the air blower 6 discharges the air to the outside of the main body. That is, the rotating drum 3 is installed in the main body so that the hot air flow port 21 on the end cover 10 side is on the windward side, and the hot air outlet 26 provided on the force support cover 11 side is on the leeward side.

Effects of the Invention As described above, according to the present invention, the welding work required when assembling the conventional metal plates forming the body of a rotating drum by curving them into a cylindrical shape is no longer necessary, or the cylindrical body and the end Seamer processing, which joins the lid button and support lid, requires several types of production equipment depending on the size of the drum, and it also takes time to change the production equipment, making it difficult to increase efficiency when producing a wide variety of products. Eliminating the need for tedious work, a rotary drum can be formed by assembling the end cover, cylindrical body, and support cover using screws using the bottomed resin cylindrical base as the base, making it easy to assemble a wide variety of drums. It is highly mass-producible.

In addition, since a compartment is formed between the bottomed cylindrical base made of synthetic resin and the cylindrical body made of metal plate, it has the effect of covering the rotating drum with a heat insulating layer, allowing energy to be radiated from the surface of the rotating drum. Since loss can be minimized, drying efficiency can be increased and drying performance can be improved.

In addition, it has been revealed that clothing containing oxidized cooking oil, etc. during drying can generate abnormal heat if left unattended after drying. Because it melts and opens due to high temperatures, new air is supplied and ignition occurs.However, in this invention, even in such cases, the ignition mechanism is blocked to prevent the formation of an air supply path, so that if one ignition burns out, the ignition mechanism is blocked. It is extremely effective in terms of safety as well. On the other hand, in conventional rotating drums made of synthetic resin, the cylindrical body has an inclined surface due to processing and molding, so the belt that is suspended on the cylindrical body to rotate the rotating drum always faces outward. This added force to the belt, making it easier to remove the belt. Alternatively, since a recess is formed in the cylindrical body of the rotating drum to form a buckle for stirring clothes, noise is generated at the discontinuous part of the cylindrical body due to this recess when the drum is rotated by the belt. In the present invention, it is possible to easily form an ideal cylindrical body while increasing assembly mass productivity, thereby making it possible to eliminate belt dislocation and generation of abnormal noise.
