動作を停止させていた。BACKGROUND OF THE INVENTION Conventionally, this type of clothes dryer has detected the temperature of the drying exhaust gas to determine when drying has ended. In other words, the exhaust temperature rises from near room temperature at the start of drying to the temperature required for evaporation of moisture, and then the temperature is maintained at a constant level as the supply of heat and the heat exhausted as steam are balanced. rate dry area),
Then, the amount of steam decreases and the supplied heat is exhausted as it is, so the steam rises. As can be seen from this characteristic, the end of the constant rate drying region can be confirmed by the rise in exhaust gas temperature, so this temperature rise was detected and the operation was stopped after a certain period of time delay.

駆動させるモータである。In FIG. 1, an outer box 1 is provided with a drum 2 in which clothes are placed and rotated. A front plate 3 rotatably supports the front part of the drum 2 and is fixed to the outer box 1, and a heat source 4 is fixed with a heater cover 6 between the outer box 1 and the front plate 3. Reference numeral 6 denotes a fan for making air into hot air through the heat source 4 and introducing it into the drum 2, removing moisture from the clothes and discharging it to the outside of the machine. A sensor 7 for detecting the temperature of the exhaust gas is provided at the exhaust portion discharged by the fan 6, and a control device 8 is provided for controlling the heat source 4 and the motor 9 based on temperature detection. Reference numeral 9 is a motor that drives the drum 2 and the 71 cylinder 6.

ΔＤ１は乾燥終了近くのΔＤに比べ著るしく激しい。To explain the operation of the above configuration, when clothes are placed in the drum 2 and the power is turned on, the heat source 4 is heated and the motor 9 rotates the drums 2, 71 and 6, blowing hot air to the drum 2.
It enters the inside of the aircraft, absorbs moisture from clothing, and is ejected out of the aircraft. At this time, the sensor 7 senses the temperature of the exhaust gas. The exhaust temperature is the second
As shown in the figure, the temperature initially rises from near room temperature to the temperature required for water evaporation, and then the heat supply and the heat exhausted in the form of steam are similar and a constant temperature is maintained (constant rate). dry area). As the clothes dry, the amount of steam decreases and the supplied heat is exhausted along with the steam, causing the temperature to rise. By utilizing this point and sensing the temperature change ΔD over a certain time Δt, dryness can be detected when the temperature exceeds a certain predetermined value after the unbalanced dry region. However, depending on the type and amount of clothing, the fabric may become tangled or unravel. At that time, if the cloth becomes entangled, the hot air will not diffuse sufficiently into the clothing and will be partially exhausted as hot air, causing a sudden rise in the temperature of the exhaust air (see the section 2 in Figure 2). It removes moisture from clothing, lowering the temperature. The temperature rise ΔD1 of the hot air when it is wrapped in cloth is significantly greater than ΔD near the end of drying.
そのためΔＤ２を０〈βくΔＤ２＜α〈ΔＤ１範囲に決
めて検知すれば途中の布がらみによる未乾燥状態で乾燥
したという誤検知を防止でき、常に安定した乾燥ができ
る。Therefore, by setting ΔD2 in the range of 0<β and ΔD2<α<ΔD1 for detection, it is possible to prevent erroneous detection of drying in an undried state due to cloth particles in the middle, and stable drying can always be achieved.
