Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a clothes dryer used in a general household, and particularly relates to a configuration for installing a temperature regulator for detecting the exhaust temperature of the clothes dryer.

BACKGROUND ART Conventionally, as shown in FIG. 2, this type of clothes dryer has a structure in which a motor 2 is provided on the upper part of an exterior body 1, and this motor 2 drives a fan 3 provided on the back side of the exterior body 1 and its fan 3. A rotary drum 4 provided in front of the fan 3 is driven to rotate via belts 5 and 6. A fan casing 7 supports the fan 3 and forms a ventilation path, and a felt seal 8 maintains airtightness between the drum 4 and the fan casing 7, and is usually fixed to the fan casing 7. Next, to briefly explain the operation, as the fan 3 rotates, hot air generated by the heater 9 provided on the front side of the exterior body 1 enters the drum 4, and after drying the clothes 10, the drum 4
is guided from the rear surface to the fan casing 7,
It returns to the heater 9 again. A temperature regulator 11 is fixed to a fan casing plate 12 in the center of the fan casing 7, and is used to prevent the temperature inside the drum 4 from rising above a predetermined temperature. As shown in FIGS. 3 and 4, the temperature regulator 11 is sealed in a tube 13 made of resin or the like to be shielded from moisture in the atmosphere, and then fixed to the fan casing 7 with a metal fitting 14. There is.

Problems to be Solved by the Invention In such a conventional configuration, if the tube 13 that protects the temperature regulator 11 is damaged by some external force, the temperature regulator 11 is directly exposed to the air containing a large amount of moisture from the drum 4. The problem is that the insulation deteriorates due to exposure, and current flows from the temperature regulator 11 connected between the power supply and the heater 9 to the metal exterior body 1 side, resulting in a risk of electric shock to the user. be. On the other hand, if a temperature controller that can be used even in a humid atmosphere is used, it becomes very expensive.

The present invention is intended to solve these problems, and aims to prevent deterioration of the temperature sensing accuracy and insulation performance of a temperature controller.

Means for Solving the Problem In order to solve this problem, the present invention includes a rotating drum rotatably supported within an exterior body, and a fan provided behind the rotating drum for blowing hot air into the rotating drum. a motor that drives the rotating drum and the fan; a fan casing that supports the fan and forms a ventilation path; and an exhaust path formed by connecting the rotating drum and the fan casing with a seal that maintains airtightness. an exhaust flow passage member that communicates between the inside and outside of the exhaust passage; and a temperature regulator attached to the exhaust flow passage body outside the exhaust passage; It has an inlet that opens toward the exhaust flow, an outlet that communicates with the inlet and opens on an opposing surface, and also forms a path from the inlet to the temperature regulator and a path from the temperature regulator to the outlet.

Effect With this configuration, even though the temperature controller is installed outside the exhaust path where it is not affected by moisture, the exhaust air inside the exhaust path that originally needs to be detected is guided outside the exhaust path. This allows the temperature sensing part of the temperature controller to detect the temperature. As a result, there is no need to cover the temperature controller with a moisture-proof enclosure as in the past, and it is possible to use an inexpensive temperature controller, and it also has excellent insulation performance and can improve safety.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIG. The basic configuration of the clothes dryer according to this embodiment is the same as the conventional configuration described above, and the explanation thereof will be omitted to avoid duplication. It should be noted that among the components used in this embodiment, the same components as those of the conventional component are given the same reference numerals. In FIG. 1, 15 is a rib integrally formed on the fan casing 7, and 8 is a felt-like seal that maintains airtightness between the rotating drum and the fan casing 7. The seal 8 thus forms a ventilation path for the exhaust air from the drum. Reference numeral 16 denotes an exhaust flow passage body that communicates the inside and outside of the exhaust passage, and has an inlet 16a opened toward the exhaust flow in the exhaust passage, and an outlet 16b opened along the exhaust flow on the back side of the exhaust flow passage body. We are prepared. In addition, a temperature controller 11 is installed outside the exhaust path.
It has an opening 16c for attaching the temperature sensing part 11a.

In the above configuration, when the equipment is operated, the exhaust gas containing moisture from the drum flows as shown by arrow A in FIG. A part of the exhaust gas enters the inside of the exhaust flow passage member 16 from the inlet 16a of the exhaust flow passage member 16, and is guided to the temperature sensitive temperature 11a of the temperature regulator provided outside the exhaust route. Thereafter, the exhaust flow passage body 16 is discharged from the outlet 16b into the exhaust path again. Therefore, although the temperature regulator 11 is located outside the exhaust path, it can detect the constantly changing exhaust gas temperature in the exhaust path, and the temperature inside the drum can be adjusted as before. In the above embodiment, the exhaust flow passage member 16 is attached separately to the fan casing 7, but the same effect can be obtained even if the exhaust flow passage member 16 is integrally formed with the fan casing 7, for example.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the temperature regulator is provided outside the exhaust path by providing an exhaust flow passage member that guides the exhaust flow in the exhaust path outside the exhaust path. Since there is no risk of the contacts inside the temperature controller coming into contact with hot and humid exhaust gas, there is no need to use a particularly sealed temperature controller, and an inexpensive temperature controller can be used. It is also possible to improve electrical insulation.
