[Problems to be solved by the device]

 The shoe dryer described in the above publication sucks the outside air with a fan, heats the sucked outside air with electric heat to produce warm air, and blows this warm air into the inside of the shoe. A relay was provided in the passage, and the relay was connected as shown in the circuit in FIG. 3, the power was turned on and off by opening and closing the relay, and the amount of heat was intermittently supplied for a certain period of time for control. That is, the heating is performed for a substantially constant time unless the setting of the heat supply condition is changed. When the power is on, if the outside air temperature is high, the temperature of the warm air blown into the shoes will be high, and if the outside air temperature is low, the temperature of the warm air will be low, the shoes will dry depending on the temperature of the outside air. It was difficult to dry the shoes under optimal conditions due to varying degrees.

That is, when the shoes are dried for a certain period of time, if the temperature of the hot air is high, the shoes are dried quickly and the drying is completed, and after that, the hot air is blown for the remaining time. The temperature of the material, etc. becomes too high and the material is damaged. On the other hand, if the temperature of the warm air is low, the shoes will not dry sufficiently and you will feel uncomfortable when you wear them, and if you leave the shoes in an insufficiently dry condition, they will cause mold and the like. Has a problem that it hurts. Further, the optimum temperature and blowing time of the warm air for drying the shoes differ depending on the type and material of the shoes.

For example, in the case of shoes made of cow leather, it is preferable to dry them at 40 ° C. or lower. When drying at 40 ° C., it is best to dry for 3 hours. In the case of shoes made of cloth, drying at 50 ° C or lower is recommended. When drying at 50 ° C, it is best to dry for 2 hours. Therefore, it was necessary to set the temperature and the blowing time of the warm air constantly blown in, which was troublesome. Therefore, it is an object of the present invention to provide a shoe drying device that does not dry too much and therefore does not damage the material of the shoe.

The warm air temperature control device 5 is assembled like the circuit shown in FIG. That is, it is composed of the temperature sensor 6 and the control circuit section 7. The control circuit unit 7 includes a power supply circuit 71, a timer 72, a phase control circuit 73, and a control circuit 74.

Next, a usage state of the shoe dryer 1 will be described. Put the shoes on the outlet 4 and set it. Next, when the power of the shoe dryer is turned on, the electric heat 3, the fan 2, and the warm air temperature adjusting device 5 move. Explaining this movable state, the outside air is sucked from the lower side by the fan 2, the sucked outside air is warmed by the electric heat 3, and the warmed hot air is blown out from the air outlet 4.

At this time, since the temperature sensor 6 is provided in the hot air passage between the electric heat 3 and the air outlet 4, the temperature measured by the temperature sensor 6 is transmitted to the control circuit 74, and this control circuit 74 outputs a signal to the phase control circuit 73 to control the output of the electric heat 3. That is, when the temperature of the warm air becomes higher than the predetermined temperature, the temperature sensor 6 senses the voltage waveform of the voltage passing through the electric heat 3 by the phase control 73 as shown by the hatched line in FIG. make low. Therefore, the temperature of the electric heat 3 decreases and reaches a predetermined temperature. When the temperature of the warm air becomes lower than a predetermined temperature, the temperature sensor 6 senses the voltage waveform of the voltage passing through the electric heat 3 as shown by the hatched line in FIG. Therefore, the temperature of the electric heat 3 rises to a predetermined temperature. In this way, the warm air discharged from the outlet 4 is always at a constant temperature, so that it will dry to an optimum state at a fixed time. After a certain period of time, the timer 72 is activated to cut off the electric current and the drying of the shoes is completed.
