Description
The utility model relates to a kind of furniture, particularly Cool and warm chair.
At present, general seat or yarn are sent out (chair) though various ways is arranged, and all do not have temp regulating function, and the hard seat chair is very cool winter, and it is too hot that yarn is sent out (chair) summer.Several constant temperature chairs appear in recent years, it as the patent No. 88221617.1 Air-ventilating soft mattresses, the patent No. be 87201992.U have a thermoregulator chair etc., the former has used semiconductor cooler to realize air-conditioning, structurally conductive plate will bear human body and cut lotus and impulsive force, junction rapid wear ring with thermal storage device, conductive plate is big, takes material, the cost height, and it is also inhomogeneous to conduct heat, big more the closer to thermal storage device place thermograde.The cushion(ing) material of this Air-ventilating soft mattresses must be thicker, otherwise that the people can feel is hard and uncomfortable, but heat transfer property reduces greatly, and the heating-up time is long, the power consumption height.The latter can only lower the temperature, and can not heat up, thereby only be applicable to summer.
The purpose of this utility model is to provide a kind of temperature adjustable, cool in summer and warm in winter Cool and warm chair.
