Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a drum-type clothes dryer used in general households.

Structure of conventional example and its problems A conventional clothes dryer of this type has a rotating drum rotatably supported within the main body, a drum front plate rotatably supporting the front part of the rotating drum, and a drum front plate rotatably supporting the front part of the rotating drum. It is equipped with a support that supports the front plate on the main body, and a lid switch that is controlled by opening and closing the lid, but since the lid switch was separately fixed to the support with screws, etc. There was a problem in that the assembly work became extremely complicated and the number of parts increased, making the total cost extremely high.

Purpose of the Invention In view of the above-mentioned conventional problems, the present invention aims to simplify the configuration, facilitate assembly work, and lower the total cost by not reducing the number of parts. .

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a dryer main body having a clothes input opening opened and closed by a lid on the front side, a dryer main body rotatably disposed within the dryer main body,
A rotating drum having an exhaust hole covered with a filter at the rear, an exhaust fan provided behind the exhaust port of the rotating drum, and a front opening edge of the rotating drum slidably touching the outer periphery of the resin molded product. A circular drum front plate fixed to the dryer body via a support, a heater installed in the intake system to supply warm air to the rotating drum, and a lid switch linked to opening and closing the lid. The lid switch has a switch case integrally formed with the support, a fixed contact plate and a movable contact plate having an operation button are housed in the switch case, and the lid switch has a switch case integrally formed with the support. is equipped with an operation part that presses the movable contact plate against the fixed contact plate through the operation button when opening/closing. According to this configuration, the switch part is fixed separately to the support with screws, etc., as in the past. This eliminates the need for this work and also reduces the number of parts, so all that is required for assembly is to attach the support that supports the drum front plate to the main body.
Moreover, since the configuration can be simplified, the total cost can be reduced.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a dryer main body having a clothes input port 2 on the front side, and a rotary drum 3 is rotatably supported within this main body 1. 4
A drum support shaft is crimped to the drum holder 5 and pivotally supports the rear portion of the rotary drum 3. A forced exhaust fan 6 is rotatably attached to the drum support shaft 4. Reference numeral 7 denotes a filter cover that is detachably attached to the rear inside of the rotating drum 3, and houses a filter 8 therein. Reference numeral 9 denotes a plurality of exhaust holes provided at the rear of the rotary drum 3 facing the filter cover 7, and the exhaust holes 9 communicate with a fan case 10 in which the forced exhaust fan 6 is housed.

Reference numeral 11 denotes a circular drum front plate, and the drum front plate 11 is connected to the section a at its outer circumference through a highly wear-resistant felt 13 attached to a flange 12 formed at the front opening of the rotating drum 3. The rotary drum 3 is rotatably supported. Further, the drum front plate 11 is located between the main body 1 and the rotating drum 3,
A support 14 for the drum front plate 11 and a heater 1 inside.
5 is fixed by a heater cover 16 containing a heater cover 16. Reference numeral 17 denotes a lid for opening and closing the clothing slot 2 of the main body 1, and the lid 17 is formed with an operating section 19 for operating a lid switch 18 provided on the support 14. 20 is a plurality of intake holes formed on the front surface of the main body 1 facing the heater cover 16; 21;
is the drum front plate 1 facing the heater cover 16.
1 has multiple small holes.

In the above configuration, the outside air sucked into the heater cover 16 through the intake hole 20 is heated by the heater 15 and becomes warm air, and this warm air enters the rotating drum 3 through the small hole 21 to dry the clothes and , filter 8 via filter cover 7
and is exhausted to the outside of the aircraft by a forced exhaust fan 6.

Figures 2a, b, c, and d show the structure of a support 14 for supporting the drum front plate 11 on the main body 1, and this support 14 is an integral resin molded product made of synthetic resin. A support part A having a height of H and a switch case B located on the side of this support part A are integrally constructed. This support 14 has holes c on the upper surface shown in FIG. 2a and holes c' on the lower surface shown in FIG. 3d, respectively.
1 with self-tapping screws.
As shown in FIG. 3c, in the switch case B, the support 14 includes the necessary components for the lid switch 18, namely, a fixed contact plate 22 with the contacts crimped thereon, and a fixed contact plate 22 with the contacts crimped thereon. The closed movable contact plate 23 and the operation button 24 for pressing the movable contact plate 23 from the outside of the switch case B are housed, and the opening of the switch case B is covered with the bar 2.
A lever 26 is attached to the switch case B, and a lever 26 is attached to the switch case B to apply a pushing force to the operating button 24 from the outside.
A support with a lid switch as shown in FIG. 3 is constructed by attaching a button 27 opposite to the operating section 19 provided on the cover.

FIG. 4 shows the state when the drum front plate 11 is attached to the main body 1, and the drum front plate 11 is attached to the second
The support 14 shown in the figure and the support 1 shown in FIG.
4 and self-tapping screws 2 to the main body 1.
Attached by 8.

In this way, in one embodiment of the present invention, the support 14 for supporting the drum front plate 11 on the main body 1 is provided.
The case B of the lid switch 18 is integrally molded from synthetic resin, and the parts necessary for the lid switch 18 are stored inside the case B, which reduces the number of parts and simplifies assembly work. It is something that can be measured.

Effects of the Invention As described above, according to the present invention, there is provided a support for supporting a drum front plate that rotatably supports the front part of a rotating drum on a main body, and a lid switch that is controlled by opening and closing the lid. Since the case and the case are made of an integral resin molded product, there is no need to separately fix the switch part to the support with screws, etc. as in the past, and the number of parts is also reduced. As a result, the assembly work only requires attaching the support for supporting the drum front plate to the main body, and the structure can be simplified, so that the total cost can be reduced.
