It is also known that a heating element such as a ceramic heater is interposed in the air passage of the spot cooler mechanism to add a function as a warm air blower to use as a cold / hot air blower.

れの方式が優れているとは一概に言えなかった。The method of advancing and retracting the heating element in the air passage has a complicated structure, and it is difficult to manufacture a low cost one. On the other hand, in the case of the method of rotating the blower forward and backward, the air passage is divided into two, but since the blower outlet is the same, the cold air passage and the warm air passage become close to each other, and the cold air during cold air operation also reaches the heating element side. There is a possibility that water vapor in the air may condense in the flow and near the heating element to cause electric leakage, and it cannot be generally said that either method is superior.
