DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a clothes dryer according to one embodiment of the present invention will be described. FIG. 1 is a side sectional view of the clothes dryer of the present embodiment,
FIG. 2 is an external front view. First, with reference to FIG. 1 and FIG. 2, a description will be given of a structure of the clothes dryer which is different from a conventional clothes dryer. Note that the same components as those of the conventional clothes dryer are denoted by the same reference numerals and description thereof will be omitted.

In this clothes dryer, as shown in FIG.
The cylindrical machine frame 1 made of sheet metal has an upper part curved in a semicircular shape, and a lower part bent so that both corners are substantially perpendicular. The curved shape of the upper part of the machine frame 1 has a diameter slightly larger than the diameter of the drum 13.

FIG. 3 is an enlarged view of a portion A in FIG. The upper portion of the cylinder cover 4 is formed in a substantially semicircular shape corresponding to the upper shape of the machine frame 1, and its edge is bent substantially vertically rearward as shown in FIG. 3. Meanwhile, machine frame 1
Is bent inward, the front edge of the machine casing 1 is fitted inside the edge of the cylinder cover 4, and the overlapped portion is made of a synthetic resin fitted outside. They are fastened together by screws 37 penetrating the front plate 2. Machine frame 1
Is easy to deform because it is a tubular sheet metal. However, by fitting to the upper edge of the cylinder cover 4 as described above, the shape can be adjusted according to the shape of the upper edge. Since the cylinder cover 4 is reinforced from the inside, the rigidity can be increased.

Next, the structure of the door of the clothes dryer and its mounting structure will be described. In this clothes dryer, the door 5 has a substantially circular shape so as to match the upper shape of the front plate 2. FIG. 4 is a front perspective view of a main part of the clothes dryer, and FIG.
Is a cross-sectional view taken along the line BB 'in FIG. 2, and FIGS. 6 to 10 are a front view and cross-sectional views of each member constituting the door 5.

FIG. 6 shows a door frame 40 made of synthetic resin, FIG. 7 shows an outer window plate 41 made of translucent synthetic resin, FIG. 8 shows a holding frame 42 made of flame-retardant synthetic resin, and FIG. Tempered glass 43, FIG. 10 shows inner window plate 4 made of transparent synthetic resin.
4. The assembly structure of these five members is as shown in the H section of FIG.

That is, the door frame 40 has a window opening 401 which is largely opened in a substantially circular shape, and a groove 402 is formed around the window opening 401. The outer window plate 41 is partially formed with a recess 411 for a door handle, and a peripheral edge other than the recess 411 is a tongue 412 bent substantially vertically. The tongue 412 is adapted to fit exactly into the groove 402 of the door frame 40, so that the outer window plate 41
Is attached to the door frame 40.

A window opening 421 having a diameter slightly smaller than the diameter of the tempered glass 43 is formed in the holding frame 42, and the periphery of the window opening 421 has a stepped glass receiving portion 4.
22. When the tempered glass 43 is loosely fitted into the glass receiving portion 422, the window opening 421 is closed by the tempered glass 43. Then, the tempered glass 43 is sandwiched between the holding frame 42 and the door frame 40, and the holding frame 42 is further sandwiched between the door frame 40 and the inner window plate 44, from the back surface (inner side surface) of the inner window plate 44. The penetrated screw 45 is screwed to the door frame 40.

The see-through window at the center of the door 5 assembled in this manner is a substantially circular plate-like heat-resistant tempered glass 43.
Is sandwiched between a synthetic resin inner window plate 44 and an outer window plate 41 in a triple structure. In the event that a fire or the like occurs inside the drum 13 during drying of the clothes, even if the resin-made inner window plate 44 burns, the holding frame 42 does not burn (because it is flame-retardant) and the tempered glass 43 falls off. Will be kept without. Therefore, combustion is stopped by the tempered glass 43, and further spreading to the outside can be prevented. Further, since the tempered glass 43 has good thermal conductivity, the temperature becomes high even during normal clothes drying.
This prevents the user from directly touching the hand, thereby preventing an accident such as a burn.

For the purpose of preventing combustion, a metal can be used as the material of the holding frame 42. However, when the holding frame 42 is formed of metal, a portion corresponding to the window opening 421 is discarded, and the material is wasted. But with high cost. In addition, of course, if a normal, that is, non-flame-retardant synthetic resin is used, the intended purpose cannot be achieved. If a flame-retardant synthetic resin is used as in the present embodiment, the desired purpose can be achieved, and the cost can be lower than using a metal.
It is more preferable to form the inner window plate 44 with a flame-retardant resin, but generally, the flame-retardant resin has poor transparency and is not suitable for such a window. Even if transparency can be obtained, the cost is considerably high.

As shown in FIG. 5, a hinge 46 is fixed to a boss 403 protruding inside the door frame 40 of the door 5 with a screw. Since the front plate 2 is made of synthetic resin, the strength is not sufficient to support the door 5 having a large load. Therefore, in this clothes dryer, a screw 49 for fixing the hinge 46 is passed through the through hole of the front plate 2 and screwed to a metal plate located inside the front plate 2. As shown in FIG. 4, the metal plate is a duct cover 48 fixed to the front surface of the cylinder cover 4 to form the drying duct 25 at a position where the lower screw 49 is attached. At the attachment position 49, the reinforcing plate 50 is attached to the front surface of the cylinder cover 4. A metal cylindrical collar 51 is inserted into the through hole formed in the front plate 2,
The stress acting on the screw 49 is not directly applied to the front plate 2 and is dispersed in the circumferential direction.
With such a mounting structure of the door 5, the door 5 can be held openably and closably with high durability.

Incidentally, since the clothes dryer has the circular door 5 as described above, the clothes dryer has the same structure as the conventional clothes dryer having a rectangular door shown in FIG. The gap between the lower end of the frame and the lowest part of the machine frame 1 becomes narrower. Instead, a large area can be secured near the lower corners. Therefore, as shown in FIG. 2, an operation panel 34 is provided at a lower right corner portion toward the front.

FIG. 11 is an enlarged view of the operation panel 34, and FIG.
FIG. 13 is a diagram showing the substrate arrangement inside the front plate 2, FIG. 13 is a state diagram when the substrate is prepared, and FIG. 14 is a state diagram when the substrate is attached to the clothes dryer. The board is composed of a P board 60 to which a 100 V commercial AC power supply line is connected, and a C board 61 on which various displays and switches corresponding to the operation panel 34 are arranged. They are connected by a line 62. The C board 61 is provided directly behind the operation panel 34, and the P board 60 is provided below the door 5.

In order to efficiently obtain (ie, as many as possible) substrates from a substrate material of a predetermined size, two substrates are processed in a linearly connected state as shown in FIG. You. Then, after cutting the substrate into a predetermined shape, the substrate is divided into two substrates. Further, as shown in FIG. 14, after components are mounted on each substrate, the components are respectively housed in a connected substrate case, and a coating process for moisture proof is performed. Then, after the processing, the connected substrate case is separated and attached to an appropriate shape as shown in FIG. As described above, in the clothes dryer, the substrate manufacturing, the coating process, and the like are performed in the state shown in FIG. 13, which is advantageous in reducing the manufacturing cost. In addition, since the high-voltage part and the low-voltage part are separated from each other, it is safe for repairs and the like.

It should be noted that the above embodiment is merely an example, and it is apparent that modifications and corrections can be made as appropriate within the scope of the present invention.
