Description

Heating and cooling cushion {Heating or cooling floor cushion}

The present invention relates to a cold and warm cushion and a heat exchanger used therein to keep a user cool or warm for a long time by maintaining cold or warm air in the cushion.

Cushions are rugs used in our sedentary culture that mainly use a room or floor as a living room to provide comfort and comfort to a seated person. Typically, cushions or cotton with cushions are used in a cloth shell. This is due to the warmth of the fabric is not to feel cold even in winter, but also to get comfort by cushions, and in summer, it is used to be a royal, stool and resin so as to increase the ventilation.

However, the above-mentioned conventional cushion can obtain warmth or coolness due to its material characteristics or external structure, so it is not possible to obtain warmth above atmospheric temperature or coolness below atmospheric temperature. Therefore, such a cushion has four distinct seasons as in Korea. In particular, there has been a disadvantage in that the cold and cold periods can not give comfort to the user.

Various attempts have been made to remedy these shortcomings, for example, the invention of 'cooling cushion using heat pipes' proposed in Publication No. 1991-0002302 (April 11, 1991), and Publication No. 10-2004-. 0066499 (published Jul. 27, 2004) has been proposed a 'method of manufacturing a cushion installed with a heat transfer heater wire and a refrigerant material', the following briefly introduces to help the understanding of the present invention.
