Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clothes dryer in which a heat source and a temperature detection means are disposed in the air passage leading to the drying chamber. It ends the operation.

In conventional clothes dryers, a timer is installed for a longer time than necessary, allowing the user to set the drying time appropriately depending on the amount of clothes, or using an expensive humidity sensor to finish drying. was.

There was a problem.

The present invention has been made in view of the above-mentioned conventional drawbacks, and is intended to ensure operational reliability and economy by completing drying only by detecting the number of interruptions of a temperature detection means, such as a thermostat.

The present invention will be explained in detail below. In the figure, reference numeral 1 denotes a housing, which houses a motor 2 at its inner bottom and a drying chamber 3 consisting of a rotating drum at its center. 4 is a belt that converts the rotational force of the motor 2 into the rotation of the drying cabinet 3; and 5 is a belt that converts the rotation of the motor 2 into the rotation of the fan 6.

The drying cabinet 3 has a front opening that can be opened and closed with a door 7, and a filter 8 is disposed at the rear inside thereof. As the fan 6 rotates, air enters the drying chamber a through its front suction hole (not shown), and this air is discharged to the outside through the filter 8. Since the air entering the drying chamber 3 is heated by the heat source 11 disposed between the heater cover 9 and the heater mounting plate 10, the moist objects to be dried in the drying chamber a are dried.

Reference numeral 12 denotes a temperature detecting means provided in the middle of the air blowing path of the fan 6, and in the embodiment, it is provided on the downstream side of the filter 8. As the temperature detecting means 12, a temperature regulating thermostat is used, and the supply of electricity to the heat source 11 is interrupted. The number of interruptions is counted by the number detection circuit 13, and when the number of interruptions reaches a preset number, the main power supply 14 is turned off.

In the above configuration, when the main power source 14, which is the AC power source, is turned on, the fan 6 starts blowing air in the direction of the arrow a, and the air heated by the heat source 11 enters the drying chamber 3, causing the damp air to dry. Dry the dried items. If this operation continues for more than a certain period of time, depending on the amount of material to be dried,
A temperature detection means 12 provided behind the filter 8 detects that the exhaust gas temperature is high and opens the energization circuit to the heat source 11. At this point, the motor 2 rotates the drying chamber 3 and the fan 6 to blow only outside air to lower the temperature inside the drying chamber 3. By this operation, the temperature detection means 12 closes the circuit of the heat source 11 again and blows hot air.

Here, the number of times the temperature detection means 12 is turned on and off is counted by a number detection circuit 13 shown in FIG. 2, and when the number of times set according to the clothes drying capacity is reached, the main power is disconnected to end the drying. It turns out.

As described above, according to the present invention, drying of clothes is completed by detecting the number of times the temperature detection means is turned on and off, and there is no need to set the timer time longer than necessary.
It is possible to prevent unnecessary drying operations, and there is no need for expensive sensors, etc., and there are effects such as a highly accurate drying completion operation can be performed at low cost.
