Abstract

The utility model discloses a heat storage warming device, which comprises a heating wire, a ceramic dish, an insulating layer, a shell and a circuit for energy conversion. The heat storage warming device is characterized in that the heat storage warming device also comprises a heating conductive layer and a thermal storage layer; the heating conductive layer is installed in the gap between the heating wire and the ceramic dish, and the thermal storage layer is installed between the ceramic dish and the insulating layer. The heat storage warming device is suitable for people warming themselves in winter, and can be used for the hot compress and the physical therapy.

Description

Heat storage warming device

The utility model relates to a kind of accumulation of heat warmer, the electrically heated accumulation of heat warmer of particularly a kind of usefulness.

It is of a great variety, too numerous to mention, traditional that winter, people were used as the utensil of heating, and warmer commonly used has hot-water bottle, metal or earthenware hot-water bottle etc.

Occurred in succession again in recent years with electrically heated accumulation of heat warmer, its heater generally adopts heating wire, after the heating wire energising, be transformed into heat energy by electric energy, add heat-resisting anticreep heat-insulation layer, heat is stored, slow release, for people's heating, this type of warmer mode of heating is simple, and temperature retention time is long, but the major defect that it exists is that thermal resistance is big, amount of stored heat is little, the easy oxidation of heating wire, shortcomings such as vibration resistance difference.

The purpose of this utility model is to provide a kind of thermal resistance little, and amount of stored heat is big, the non-damageable accumulation of heat warmer of heating wire.

The purpose of this utility model is to realize like this; Warmer comprises by electrothermal relay RJ(8), current-limiting resistance R1(11), light emitting diode D(12), supply socket (9) and heating wire R(7) power conversion circuits (13) formed, be used to place the ceramic disk (6) of heating wire, be located at the heat-resisting anticreep heat-insulation layer (3) of ceramic disk outside and be located at housing (2) outside the heat-insulation layer (3), it is characterized in that it also comprises one deck heat-conducting layer (5), with one deck recuperation layer (4), described heat-conducting layer (5) is provided in a side of heating wire R(7) and ceramic disk (6) between the space in, described recuperation layer (4) is provided in a side of between ceramic disk (6) and the heat-insulation layer (3).

The utility model has the advantages that: warmer is owing to set up heat-conducting layer and recuperation layer; again because heat-conducting layer is directly to contact with heater (heating wire) and ceramic disk with recuperation layer; and heat conduction; be full of with heat-storing material that institute has living space around it; therefore it is not fragile not have air thermal resistance heating wire therebetween; heat-conducting layer and recuperation layer quick heating, and the temperature of heater self can be not too high, thus protect and prolong the life-span of heater effectively.This warmer amount of stored heat is big, charges and discharge ratio of specific heat＞1:30.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is a line map of the present utility model.

Describe the utility model concrete structure in detail below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, Fig. 1 are structure charts of the present utility model.Fig. 2 is a line map of the present utility model.Warmer comprises heating wire R(7), be used to place the ceramic disk (6) of heating wire; At heating wire R(7) and ceramic disk (6) between the space in be provided with heat-conducting layer (5); be provided with one deck recuperation layer (4) in ceramic disk (6) outside; be only heat-resisting anticreep heat-insulation layer (3) in the outside of recuperation layer (4); in the outside of heat-insulation layer (3) is exactly the housing (2) of warmer; outside at housing (2) can also be provided with a protective bag (1) again; inside at warmer also is provided with by electrothermal relay RJ(8); current-limiting resistance R1(11); heating wire R(7) and the power conversion circuits (13) formed of supply socket (9) light emitting diode D(12).At recuperation layer (4) and electrothermal relay RJ(8) between connect a heat-conducting plate (10), heat-conducting plate (10) is by metal material, iron plate for example, corrosion resistant plate or copper coin etc. make, the purpose of setting up heat-conducting plate is in order to conduct heat evenly, described heat-conducting layer (5) and recuperation layer (4) are by kaolin or alundum (Al, silica, zinc oxide, the compounds of forming with magnesia etc. mix the coating of back coating formation with a kind of curing materials, described curing materials can be a sodium metasilicate, or No. seven magnesium elements etc.This warmer can make the series of products of different capacity as required.

Now be that 500W is the using method of example explanation warmer with power; Supply socket (9) need only be connected attaching plug, light emitting diode D(12 during use) bright, through about 5 minutes, electrothermal relay RJ(8) tripping automatically, attaching plug is taken off in outage.The warmer shell can be warming up to 95 ℃, warms oneself for the people in the time of the heat slow release.
