Description

[Detailed description of the invention] This invention relates to the mounting structure of clothes dryers, especially the heater changeover switch, by installing the changeover switch through two-stage insulation, which improves safety and reduces the number of man-hours required for installing the changeover switch. The purpose of the present invention is to provide an inexpensive clothes dryer.

Conventional clothes dryer heater selector switch mounting structure is such that the iron plate base of the selector switch is directly fixed to the front of the device using screws, so there is no two-stage insulation and the switch is attached using multiple screws. For,
It required a lot of man-hours.

The present invention solves these conventional drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings. A rotating drum 2 rotatably supported within a device body 1 is provided, and a fan 4 rotating within a fan case 3 is provided behind the rotating drum 2.

The drum 2 and the fan 4 are rotated by a V-belt 8 and a fan belt 9, which are hung around a drum pulley 6 and a motor pulley 7, which are fixed to the rotating shaft of the drive motor 5.

Reference numeral 10 denotes a self-heating heater made of a heating element having a positive resistance-temperature characteristic, which is fixed to the heater case 11 and located between the inside front surface of the device body 1 and the drum support plate 12, and covers the clothes slot 13. The door 14 is provided with an intake port 15 facing the heater 10.

A heater changeover switch 16 that changes the heat generation capacity of the heater 10 is located at the front lower part of the main body 1, and is also connected to a plurality of locking parts 19 provided in a recess 18 of a switch mounting plate 17 made of synthetic resin. The iron plate base 20 of the changeover switch 16 is held, and the switch mounting plate 17 is fixed to the front surface of the device main body 1 with screws 21.

The locking portion 19 of the switch mounting plate 17 is sloped 22 and has elasticity to fix the iron plate base 20, and the protrusion 23 of the switch mounting plate 17 is inserted into the hole 24 of the iron plate base 20. The position is regulated based on the location. In addition, 26 is a time switch, 27 is a knob inserted into the shaft of the time switch 26, and 28 is a decorative board.

In the above configuration, air taken in by the rotation of the fan 4 passes through the intake port 15 of the door 14 and is heated by the heater 10. The heated hot air is
It enters the drum 2 through the ventilation hole of the drum support plate 12, exchanges heat with the clothing, passes through the fan case 3 at the rear of the drum 2, and is heated by the rotating fan 4 to the main body 1 of the device.
Exhausted outside. The heater 10 can be switched between strong and weak states by selecting and pressing the button 25 of the changeover switch 16.

As described above, according to the clothes dryer of the present invention, by attaching the iron plate base of the changeover switch to the synthetic resin switch mounting plate, the changeover switch has a two-stage insulation structure, which improves safety. Since the iron plate base is fixed by the plurality of locking parts integrally formed on the switch mounting plate, there is no need for conventional installation with screws, which reduces the number of installation work. Since the iron plate base is fixed by the locking part and protrusion, there is no wobbling of the base in the front and back, left and right, and up and down directions when the push button switch for changing the heater is operated, and it can be securely fixed. The button will not hit the button, making it difficult to operate the button, and will not damage the button surface. Further, the position can be regulated by the hole provided in the base of the changeover switch and the protrusion provided in the switch mounting plate, and the base of the changeover switch can be reliably fixed in a predetermined position.
