る。Explaining the curve shown in FIG. 9, the temperature in the inner tub 4 rises until time t1 by starting the drying operation and gradually drying the laundry. This process is usually called the preheat drying process. Then, from time t1 to time t2, the drying progresses while maintaining a constant temperature T1. The drying temperature in the inner tub 4 is kept constant at the constant temperature T1 because the amount of heat supplied by the warm air blowing means and the amount of heat used for water evaporation of the laundry are balanced. This step is usually called a constant rate drying step, and the temperature T1 is called a constant rate drying temperature.

る。Then, when the temperature reaches the predetermined temperature T2, the heater 16 in the warm air blowing means is turned off to blow cold air. This process is commonly referred to as the cooldown process. In this process, the surface temperature of the laundry is lowered so that the user can easily take out the laundry. Then, time t4
After blowing cold air for a certain period of time, the drying process is completed.

ことがあった。When a large amount of oily stains such as edible oil adheres to the laundry and cannot be completely removed by washing and remains, the temperature in the inner tub 4 is raised to about 65 ° C. and dried. Then, the edible oil remaining on the surface of the laundry was oxidized by heat, and eventually turned yellow and became visible as stain stains on the laundry surface.

濯物が発火に至ることもあった。Even in that case, a part of the laundry may be in a high temperature state of about 65 ° C. due to residual heat. If the laundry is left in this state, oil stains such as edible oil remaining on the laundry are gradually oxidized. However, depending on the type of edible oil, self-heating may occur, which raises the surface temperature of the laundry and causes carbonization of the laundry and, in some cases, smoking. Further, when self-heating further proceeds, in the worst case, the laundry may be ignited.
