Abstract

The utility model relates to a cold-heat mattress. A semiconductor refrigerating and heating device, a radiator and a centrifugal fan are arranged and fixed in a mattress frame which has the function of supporting, a heat insulation layer is attached tightly at the lower side of a mattress surface, and a cold-heat conduction sheet is arranged between the semiconductor refrigerating and heating device and the heat insulation layer. The radiator then is arranged at the lower part of the semiconductor refrigerating and heating device, the circumference of the radiator is provided with the centrifugal fan, and the side surface of the bottom of the mattress is respectively provided with air vents. The utility model is a cold-heat mattress which can adjust cold and heat and can be used comfortably for each season.

Description

A kind of cold and hot pad

The utility model relates to the mat in a kind of daily living article.

At present, the mat of selling on the market is as function singlenesses such as cushion, back cushions.Only the mat top layer being made with summer sleeping mat, bamboo chip of having in summer,, or then make the top layer with fleece lined goods and other thermal insulation cloths in winter as the way that makes people's feeling cool.Though these ways also can allow the people feel pleasantly cool or warm sensation, can not can both use in winter, summer, thereby use and always make us feeling not to be very convenient.

The purpose of this utility model aim to provide a kind of regulate cold and hot, can be at the cold and hot pad of comfortable use in each season.

The purpose of this utility model realizes by following manner:

The utility model comprises pad face, heat-insulation layer, the cold heat transfer sheet of biography, semiconductor refrigerating heat-producing machine, radiator, centrifugal blower, switch, mat framework, semiconductor refrigerating heat-producing machine, radiator, centrifugal blower are mounted in the passive mat framework, be glued with heat-insulation layer under the pad face, be the cold heat transfer sheet of biography between semiconductor refrigerating heat-producing machine and the heat-insulation layer, radiator then is arranged at semiconductor refrigerating heat-producing machine bottom, and centrifugal blower being installed at its periphery, the tassel side is respectively equipped with ventilating opening.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is semiconductor refrigerating system electrical schematic diagram.

As shown in Figure 1, the utility model comprises pad face 1, heat-insulation layer 2, passes cold heat transfer sheet 3, semiconductor refrigerating heat-producing machine 4, radiator 5, centrifugal blower 6, alteration switch 7, mat framework 9.Pad face 1 lower floor is a heat-insulation layer 2, heat-insulation layer 2 bottoms are provided with and pass cold heat transfer sheet 3, be close to semiconductor refrigerating heat-producing machine 4 with the cold heat transfer sheet 3 of biography, the semiconductor refrigerating heat-producing machine can be sleeved on the not cotton plate with heat-blocking action, 5 in radiator is arranged at semiconductor refrigerating heat-producing machine 4 bottoms, and centrifugal blower 6 being installed at its periphery, whole tassel two sides are respectively equipped with ventilating opening 8, can lead to centrifugal blower 6 heat is delivered to the outside.Semiconductor refrigerating heat-producing machine 4, radiator 5, centrifugal blower 6 can be mounted in the passive mat framework 9.

As shown in Figure 2, semiconductor refrigerating heat-producing machine 4 for its operation principle of TEC semiconductor refrigerating heat-producing machine is: P-type semiconductor element and N-type semiconductor element are coupled to thermocouple, after connecting dc source, can produce the temperature difference and transfer of heat in the joint, a joint in the above, the sense of current is N → P, temperature descends and heat absorption, this be cold junction and under the joint, electric current is P → N, and temperature rises and heat release, is the hot junction, some semiconductor thermocouple being together in series on circuit, then is in parallel aspect heat transfer.Like this, 4 upper end heat absorptions of semiconductor refrigerating heat-producing machine, lower end heat release, Q among Fig. 2 _ABe heat absorption, Q _BBe heat release, and in time extract extraneous by ventilating opening 8 heat by radiator 5 and centrifugal blower 6.

When the utility model heats when needs, only need the reversal of power setting, then hot, the cold junction position changes, and realizes cold and hot pad heat-production functions.

The utility model in use, can be according to cold and hot needs, mix up alteration switch, transformer plugs in, the 220V alternating current is transformed into the 12V direct current, makes the acting of semiconductor refrigerating heat-producing machine, produce cold temperature or hot temperature and be passed to cold heat transfer sheet 3, be stored in the heat-insulation layer, again by heat-insulation layer with the cold or hot pad face that is distributed to.The material of pad face can be plastic material, or the flannelette material, multiple material such as bamboo chip.The mat framework also can be used making such as timber, aluminium, plastics.

The utility model is easy to use, makes simply, and cold and hot the adjusting, the four seasons are suitable for.The applicable multiple uses such as cushion, back cushion, mattress, sofa cushion of doing.Can also be with fixedly connected making such as chair, bed, sofas.
