Abstract

The utility model belongs to an air conditioning which comprises a box type mattress supporting body and a frame type supporting surface on the supporting body, wherein, a semiconductor cold and thermal device which is provided with an inner and an outer cavity bodies and a micro circulation fan is also arranged in the supporting body. Cold air can flow out from the slits of the frame in summer so as to directly reduce surface (mattress surface) temperature, the cold air can also directly act on human bodies through mattress holes so as to radiate heat, and the utility model can also heat air for thermal protection in winter. The utility model usually can reduce or increase indoor temperature for 3 to 7 DEG, and therefore, the utility model has the characteristics of cool in summer and warm in winter. The utility model overcomes the disadvantages of poor cooling effect in summer of forced ventilation type mattresses which needs additional air heating devices in winter.

Description

Air-conditioning bed cushion

The utility model belongs to the mattress of the daily sleep usefulness of people, particularly a kind of mattress that is provided with air refrigeration and heater in mattress.

At notification number is to disclose a kind of " family expenses forced ventilation mattress " among the CN2063374U, this mattress comprises mattress supporting mass and blower fan and the air filter that upper, middle and lower layer and baffle plate are all around formed, utilize blower fan air to be sent into by force the intermediate layer of mattress supporting mass when use summer, an air-flow part flows out from the mattress upper strata, another part flows out from side shield, thereby heat is taken away, realized the purpose of reducing temperature of heatstroke prevention; Then will send into the purpose that reaches heating by blower fan during winter through the air of heating.This mattress is in summer, owing to be to flow out through the mattress upper strata after sending into air at room temperature in the mattress again.Air themperature does not reduce, and in fact only is the purpose that is used for reaching cooling of having quickened bed surface and the convection current of human body surrounding air; Then be equipped with in addition air heating apparatus winter and in blower fan is sent into mattress, reach the purpose of heating again after with air heat.Therefore, this class mattress exists the effect of preventing heatstroke and lower the temperature summer relatively poor, need add defectives such as air heating apparatus in addition and be used to winter heat.

The purpose of this utility model is that design a kind ofly has hot and cold wind generation apparatus in the mattress supporting mass, and the mattress that the upper support face of mattress had both been had elasticity, can have been breathed freely, with reach Xia Liang, the winter is warm and purpose such as suitable Various Seasonal use.

Solution of the present utility model is that the mattress supporting mass is designed to case structure, and its top adopts hoop to make bearing-surface, and inner chamber is provided with the conductor refrigeration sheet as air refrigeration and heater, adopts mini fan as air circulation device simultaneously.Therefore, the utility model comprises box-type mattress supporting mass, and its upper support face is the hoop structure, is provided with hot and cold device of semiconductor and air circulation fans in the supporting mass inner chamber; The hot and cold device of semiconductor is fixed in supporting mass inner chamber middle part, circulating fan then is individually fixed in two air inlet places of hot and cold device, the hot and cold device of semiconductor comprises inside and outside two cavitys that function can be changed mutually, and when inner chamber was the refrigeration chamber, exocoel was the heat radiation chamber; When inner chamber during as heating chamber, exocoel then is the refrigeration chamber; In inner chamber, also be provided with wire netting to improve its efficient.And function conversion relies on the polarity (positive and negative electrode) that changes the conductor refrigeration sheet to realize.In order to improve result of use, in the supporting mass cavity, also be provided with a dividing plate, it is divided into two parts, be respectively air at room temperature chamber and cold (heat) air chamber, cooling and heating device then is fixed on this dividing plate.The utility model can directly be spread bamboo mat or straw mat on the hoop bearing-surface when using summer; Cold wind overflows through the hoop slit both can directly make dishes served at a feast cooling, flowed out through the mat hole simultaneously and also can divide heat to take away upper body part; Then filling up the heat keeper face season in spring and autumn, can use as routine; Then the positive and negative electrode conversion of the current input terminal of hot and cold device semiconductor-on-insulator refrigerating sheet can be sent into warm braw in mattress in the time of in the winter time.

The utility model is owing to be provided with the hot and cold device of air at mattress supporting mass middle part, bearing-surface adopts the hoop structure, therefore the air after refrigeration or heating can overflow by uniform hole on the hoop face, when the hot employing of weather bamboo (grass) seat is made the pad face, the cold air that overflows both can reduce the temperature of mat, can see through the seat hole again and directly act on human-body radiating, and cloth cover is big, flow velocity is low owing to the cold air that sees through the dishes served at a feast divides, and does not also cause the people to catch a cold.And hot-air overflowed through the face of stretching tight and was used for heat tracing winter, can suitably improve the temperature of its conventional pad face again, played warming effect; Then can use as routine season in spring and autumn.The hot and cold wind apparatus of this mattress in use can reduce air at room temperature or improve 3～7 degree.Therefore, the utlity model has and use characteristics such as nice and cool, that winter is warm and versatility is stronger summer.
