ホコリが詰まると警報装置が働くようになった。Effect: With this configuration, when the lint filter is clogged with lint, the amount of air passing through the intake section decreases, and the TC heater is heated, increasing the resistance value and lowering the current value. The maximum current when the power supply is powered manually (hereinafter referred to as inrush current) is constant regardless of the wind -1, and this inrush current and the subsequent stable current (
(hereinafter referred to as stable current) increases as the air volume decreases. In addition, the alarm device is activated when the ratio of inrush current to stable current reaches a certain value, so even if there are differences in the input values of individual PTC heaters, the lint filter is always stable. Fixed: -1 or more'' - When the dust becomes clogged, the alarm system will start working.

者に知らせる。When the drum 2 is operated with clothes placed in it, the heater 3 and the motor 6 are energized, and the hot air enters the drum 2 from the heater 3 near the intake air 1, absorbs the moisture from the clothes, passes through the filter 4, and is sent to the fan. 5, the lint is discharged from the exhaust port to the outside of the machine.At this time, the lint attached to the clothes is collected in the filter 4.As shown in Fig. 2, when the power is turned on, the current of the heater 3 increases rapidly. (inrush current)
When the heater 3 becomes hot, the resistance increases and the current value decreases. The heater 3 is cooled by the air sucked in by the fan 5, and the energy generated by the heater is balanced, so that the current value continues at a constant value. If this current value is defined as a stable current (Vc), this current changes depending on the wind: 11. Therefore, when the air volume decreases, the heater 3 is heated, the resistance value increases, and the current value decreases (V'c).
. Since the maximum current (Vm) when the power is turned on reaches its upper limit instantaneously, it is not affected much by the air volume and remains a constant value for each heater. Therefore, if the ratio between the maximum current (Vm) and the stable current (Vc) is expressed by the formula V c / V m = K, when this K reaches a certain value or more? By leaving the 'fN device active, it is possible to reliably detect the situation where the filter 4 is clogged with lint and the wind t1 is falling, and this signal activates the alarm system to alert the user. Let me know.

る。Therefore, it is possible to know exactly when to clean the filter, and by cleaning it, the force of air blowing to the heater is improved, and drying is carried out smoothly. Furthermore, since the current value is reduced by comparing the inrush current and the stable current, it is possible to reliably sense a change in current due to a clogged mouth and issue an alarm. In addition, the condition of the lint filter in the clothes dryer can be determined immediately after the clothes are put in, which has the effect of effectively taking countermeasures against clogged clothes.
