PURPOSE:To enable to linearly change the temperature in a 'Kotatsu' built under floor, by changing convection of air by slidably providing siding panels having breather slots to a 'Kotatsu'. CONSTITUTION:When two sliding panels A and B are overlapped to each other, cool air C rapidly flow to the inside of a warmer, and convection of air heated by a heater 3 is increased. A thermostat 4 is cooled by the cool air, increasing the electrical conductivity, and increasing the temperature inside the 'Kotatsu'. On the contrary, when breather slots 2 are not completely overlapped to each other, the air C is prevented from coming into the inside of the 'Kotatsu' by the sliding panels, so that convection of air is extremely decreased, the temperature inside the 'Kotatsu' frame 1 is easy to rise, and heat conductivity to the thermostat 4 is increased, while the electrical conductivity in it is decreased. In such a manner, the temperature in the 'Kotatsu' can be changed linearly by changing the area of breather slots 2 on the sliding panels linearly. |
