Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a clothes dryer for general household use.

[Prior Art] A conventional clothes dryer of this type had the configuration shown in FIG. In FIG. 5, l is the main body of the clothes dryer, 2 is a heating element serving as a heat source, 3 is a rotating drum for storing and drying clothes, 4 is a blower fan, 5 is a fan case for storing the blower fan, and 6 is a rotating drum for storing and drying clothes. is a motor that rotationally drives the blower fan 4 and the rotary drum 3. Reference numeral 7 denotes an exhaust port provided to exhaust water vapor and hot air removed from the clothes 8 in the rotating drum 3 by the ventilation fan 4. Reference numeral 9 designates a front plate on which a rotating drum 3 as described later is attached or pivotally supported in front of the rotating drum 3.

In the configuration described above, when the motor 6 rotates, the rotating drum 3 and the ventilation fan 4 rotate.

The air heated by the heating element 2 becomes hot air and is introduced into the rotating drum 3. This hot air dries the clothes 8 transferred therein by the rotation of the rotating drum 3. The water vapor removed from the clothes by this drying action is discharged to the outside of the main body 1 from the exhaust lower via the fan case 5 along with the hot air.

As shown in FIGS. 6 to 8, the rotary drum 3 of such a conventional clothes dryer has a flange 11 having a bearing inner circumferential lip 10 at the front, which is rotatably supported by the front plate 9, and a cylindrical shape. It is formed from a body 12 and a disc-shaped end plate 13,
These are integrated into the flange 1 as shown in Figure 7.
1 adhesive and a caulked portion 14 is formed on the periphery of the end plate 13;
Seams were processed at the front and rear of the fuselage 12, respectively.

Furthermore, the baffle portion 15 for stirring the clothes is formed by bending a thin plate for forming the body 12 of the rotating drum described above.

[Problems to be Solved by the Invention] In the above-described configuration, as shown in FIG. 9, in order to improve the stirring performance, the height Something big is required. In this case, the baffle 15 is formed by bending the drum body 12.
is formed, so the length of sx Y is the flange 1
The distal end 16 protrudes inward from the distal end 16, and since the inside of the distal end 16 is hollow, clothing may get caught, and it is also dangerous from a safety standpoint. ) was required.

In addition, as shown in FIG. 10, as a means of improving stirring performance, there is a problem in that when attempting to form a protrusion 17 at the tip of the baffle 15, it is impossible with the conventional structure and manufacturing method of the drum body 12. was there.

Further, the conventional method of forming the rotating drum 3 requires seam processing using the caulking portion 14 described above, which requires large-scale equipment such as a seam processing machine, and increases in fixed costs are unavoidable.

Therefore, an object of the present invention is to eliminate the need for seam processing as described above, and to eliminate the need for the tip portion 16 of the baffle 15 to be hollow.
The purpose of the present invention is to provide a drying machine equipped with a drying drum in which a baffle having an arbitrary shape such as a protrusion can be easily formed and easily installed in the rotary drum 3.

[Means for solving problems]

The present invention includes a dryer main body, a heating element, a rotating drum, and a blower fan, and the rotating drum includes a flange having a bearing inner peripheral lip at the front, a cylindrical body, a disc-shaped end plate, and a plurality of dryers provided on the cylindrical body. The clothes dryer is composed of a substantially triangular prism-shaped baffle, and the triangular prism-shaped baffle has its side surfaces fixed to the inner wall of the body, and its both end surfaces fixed to the flange and the end plate.

That is, according to the present invention, the baffle is formed separately, and the cylindrical body of the rotating drum is formed only from a complete body without the conventional bending process for forming the baffle.
The baffle is a substantially triangular solid column, and the intestinal body, flange, and end plate are attached and fixed to this.
This made it possible to form a rotating drum.

[Effect]

With the above-mentioned configuration, the parts can be formed separately in any desired shape in a solid state, and can be used as pillars to form the drum body, flanges, rear end plates, etc. as shown in the embodiments described later. For example, by fixing it with screws.
(The rotating drum can be integrated, that is, manufactured.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. This embodiment is the same as the conventional example except for the detailed structure of the rotating drum, so the same reference numerals as used in the description of the conventional example are used for parts that do not require changes.

Therefore, 1 is the main body of the washing machine, 2 is the heating element, 3 is the rotating drum, 4 is the blower fan, 5 is the fan case, 6 is the motor, and 7
is the exhaust port, 8 is the clothing, 9 is the front plate, and these are the fifth
As shown in the figure.

According to the present invention, as shown in FIGS. 1 and 2, the rotating drum 3 has a flange 11 having a bearing inner circumferential lip 10 that is pivotally supported by the front plate 9, and has a plurality of through holes for passing screws 18. A hole 19 is provided.

Furthermore, the body 12 for the rotating drum 3, which should be located at the center, is formed by winding a thin strip 20 into a cylindrical shape as shown in FIGS. 3 and 4 [without the conventional bending process] One end 21 of the thin plate 20 is overlapped with the other end 22, and the through holes 23 and 23' provided near both ends are made to coincide with each other. At this time, it is aligned with a female thread provided on the side surface of a baffle 25, which will be described later, and fixed with a screw 29. Further, the end plate 13 is also provided with a through hole 24 to which a baffle 25 is screwed.

[As shown in FIG. 1, the baffle 25 is separately formed in the shape of a solid triangular prism, and is provided with a side surface 26 to be attached to the body 12, and a female threaded portion 2B on both sides 27 and 27, respectively. The body 12 and the baffle side 2 are connected by screws 29.
6, and the screws 18 connect the flange 11 and the baffle end face 27, and the screws 30 connect the end plate 13 and the baffle end face 2.
7' is fixed. In this way, the rotating drum 3 is integrally formed as shown in FIG.

In the above-mentioned example, the baffles 25 are fixed with screws, but they may also be fixed with soldering.

〔Effect of the invention〕

As is clear from the description of the above embodiments, according to the present invention, when forming a rotating drum, the baffles can be formed separately into a solid column shape, which eliminates the need for conventional bending of thin plates. The baffle can be formed into any shape, size, and height. Furthermore, since the baffle can be easily attached and fixed at the same time as the rotating drum is integrally formed, conventional equipment such as a seam processing machine is not required.

In addition, individual parts can be manufactured and transported separately, so rationalization can be achieved.
