Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clothes dryer in which drying control is performed by a temperature detection sensor, and more particularly to mounting of a temperature sensor.

2. Description of the Related Art Conventionally, this type of clothes dryer has a structure as shown in FIGS. 4 and 5. That is, the rotary drum 2 rotatably supported in the main body 1 has an intake port 2a formed in the front surface and an exhaust port 2b formed in the center of the rear surface. The exhaust port 2b is covered with a filter 6. A fan case 7 having an opening 7a at a position facing the exhaust port 2b is provided at the rear of the drum 2. In the fan case 7, the intake port 2a
There is provided a fan 7b that draws out the hot air 4 heated by the heating element 3 disposed upstream of the above into the drum 2. This fan 7b applies hot air 4 to clothes 5 and then filters 6, exhaust port
It is introduced into the fan case 7 through 2b and the opening 7a. The introduced hot and humid air and cooling air are heat-exchanged on both sides of the fan 7b, and after dehumidifying, blown again to the heating body 3 to form a circulation path for blowing the heated hot air into the drum 2 to form clothes. 5 is dried. In order to detect the dryness of the clothes, a temperature detecting sensor 8 is attached to a fan case reinforcing plate 9 provided in the opening 7a. If the temperature detecting sensor 8 is directly attached to the reinforcing plate 9, water drops may adhere to the surface of the temperature detecting sensor 8 due to the hot and humid air, resulting in erroneous detection. Therefore, the surface of the temperature detection sensor 8 is covered with the resin material 11 to prevent water droplets from directly adhering thereto.

Problems to be Solved by the Invention However, in the conventional configuration, the temperature detection sensor 8 is made of the resin material 11
Since it was necessary to cover the same with other factors, many man-hours were required and mass productivity was lowered. Further, since this temperature detecting sensor is fixed only by the metal band 10, there is a problem that the sensor 8 may come off during temperature detecting and transportation.

The present invention solves the above problems, and an object of the present invention is to reduce the number of working steps and to stably fix the temperature detection sensor to prevent the temperature sensor from coming off.

Means for Solving the Problems To achieve the above object, a clothes dryer of the present invention is provided with a main body of a dryer, a rotary drum rotatably provided in the main body, and a rear portion of the rotary drum. A fan that introduces hot air from an exhaust port on the rear surface of the rotary drum, a fan case that covers the fan and has an opening at a position facing the exhaust port of the rotary drum, and a motor that drives the rotary drum and the fan A case for accommodating the lead wire of the temperature detection sensor by forming a groove from the outer peripheral direction toward the opening on the outer surface of the fan case facing the rear surface of the rotary drum and extending the groove to the opening. Provided in this case, the temperature detection sensor drawn out from the groove is embedded in the filler and housed therein, and a reinforcing plate having an inlet and an air vent for injecting the filler is attached to the case so as to cover the case. It is a digit.

Function According to this configuration, the temperature detection sensor can be securely fixed by the simple assembly work in which the temperature detection sensor is housed in the case and attached to the reinforcing plate, and the filling work is easily performed because the case is filled with the filling agent. It can be done, and water droplets do not directly adhere to the surface of the temperature detection sensor.

EXAMPLES Examples of the present invention will be described below with reference to FIGS. 1 to 3.

As shown in FIG. 1, the clothes dryer according to the present embodiment has a drum 12 rotatably supported in a main body 13 having an intake port 12a at the front and an exhaust port 12b at the rear. An opening 18a is provided at a position facing the exhaust port 12b covered with the filter 17.
Is provided with a fan case 18, in which the hot air 15 heated by the heating element 14 is applied to the material 16 to be dried in the drum 12 and introduced into the fan case from the exhaust port 12b. It has 18b. The fan 18b exchanges heat on both sides to dehumidify the hot and humid air from the drum 12. A fan case reinforcing plate 21 having a plurality of ventilation holes is attached to the opening 18a of the fan case 18. A temperature detection sensor 19 for detecting dryness is attached to the fan case reinforcing plate 21.

The mounting of the temperature detecting sensor 19 will be described in detail with reference to FIGS. 2 and 3. That is, the lead wire 19a of the sensor 19 is housed in the groove 20 formed from the opening 18a of the fan case 18 to the outer peripheral portion, and is covered by the lid cover 27. Further, the sensor 19 is mounted in the sensor case 24 by inserting the claw 23 into the hole 22 provided in the reinforcing plate 21. Moreover, the reinforcing plate 21 is provided with an injection port 25 for filling the moisture-proof sealing material of the sensor 19 and a hole 26 for bleeding air when the sealing material is injected, at a position where the sensor case 24 is attached. It makes the work easier.

EFFECTS OF THE INVENTION As is clear from the above embodiments, according to the present invention, it is possible to carry out a simple assembling operation of accommodating the temperature detecting sensor in the case and attaching it to the reinforcing plate, and the number of steps is reduced. In addition, since the temperature detection sensor injects the filler into the case, there is no erroneous detection. Furthermore, the lead wire of the temperature detection sensor is stored in the groove provided in the fan case to prevent the lead wire from contacting the drum. can do.
