Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a dryer suitable for drying simple clothing such as underwear, which utilizes a hair dryer as a hot air supply source.

[Conventional technology]

JP-A-60-5198 discloses a conventional technique for drying clothes using a hair dryer as a hot air supply source. This consists of a stationary clothes dryer equipped with a rotating drum for storing clothes, an exhaust fan, a heater for heating dry air, etc., and a hair dryer.The hair dryer can be attached or detached from the air intake of the clothes dryer. It is meant to be worn.

[Problem that the invention attempts to solve]

The basic specifications of a hair dryer are determined based on the hot air temperature, hot air volume, and time required for drying hair. Therefore, when using a hair dryer for purposes other than its intended purpose as described above, it must not be used beyond its performance or subjected to an abnormal heat load.

Generally, the amount of heat required for forced drying of clothes is much larger than the amount of heat that can be generated by a hair dryer. For this reason, when drying clothes using a hair dryer, connected operation is often performed for a long period of time, which tends to apply an abnormal heat load and easily lead to overheating. If the hair dryer is overheated, the built-in thermostat will activate and force the hair dryer to shut down, leaving clothes partially dry. If a thermostat is not installed, the plastic outlet grille and the case surrounding the heater may burn out or become deformed due to heat.

This invention solves the above-mentioned problems when drying clothes using a hair dryer, and allows the dryer, which is essential for drying clothes, to run continuously for a long time, thereby reducing the need for using the hair dryer. The main objective is to make it possible to dry clothes under more suitable operating conditions.

[Means for solving problems]

As shown in FIG. 1, the simple clothes dryer of this invention includes a hair dryer 1, a clothes storage body 2 for storing clothes A, and a connection unit 3 for connecting the two.
When the hair dryer 1 is connected to the connection unit 3, the heater 9 of the hair dryer 1 is controlled via the heater control circuit 38 provided in the connection unit 3.
is connected to a power source, and the voltage supplied to the heater 9 is lowered to a potential suitable for long-term operation. In other words, this invention lowers the temperature of the hot air to prevent the hair dryer from overheating, allowing it to operate for long periods of time.

Specifically, hair dryer 1 and connection unit 3
Connectors 24 and 35 are provided at the connection portions of the hair dryer 1, respectively, and the control circuit 16 of the hair dryer 1 and the heater control circuit 38 built in the connection unit 3 can be connected through the connectors 24 and 35, respectively. In the connected state, the heater control circuit 38 is interposed between the heat generating section 18 including the heater 9 of the hair dryer 1 and the power source, and reduces the voltage applied to the heater 9. Preferably, a variable resistor 40 is provided in the heater control circuit 38 so that the amount of heat generated by the hair dryer 1 can be adjusted depending on the object to be dried.

[Effect]

By connecting the hair dryer 1 to the connection unit 3, the heater 9 of the hair dryer 1 is connected to the power source via the heater control circuit 38 provided in the connection unit 3. When the hair dryer is operated in this state, a current with a potential lowered by the heater control circuit 38 is applied to the heat generating section 18, and the amount of heat generated by the heater 9 is reduced.

[Effect of idea]

As described above, in the simple clothes dryer of the present invention, when the hair dryer 1 is used for drying clothes, the voltage supplied to the heat generating section 18 is lowered by the heater control circuit 38 of the connection unit 3, and the heater 9 generates heat. Since the amount is forcibly reduced, even if continuous operation is performed for a long period of time, there is no overheating, and clothes drying can be carried out easily under suitable operating conditions. This may cause the thermostat to activate during drying, interrupting the drying process, or turning off the hair dryer 1.
It is possible to reliably prevent the case etc. from being burnt out or thermally deformed due to overheating. A simple clothes dryer using such a hair dryer 1 is suitable for drying light clothing such as underwear, and by forming the clothes storage body 2 with a cloth bag, the hair dryer 1 can be used for multiple purposes by being carried when traveling etc. It is also suitable for
