Abstract
The utility model discloses a heating box belonging to an electric heating device. The utility model aims to provide a box type heating device having the advantages of simple structure, high safety and reliability and long service life. The heating box comprises a box body (2) of an open top, an electric heating element and a control device. The electric heating element is arranged in the box body (2), and the control device is fixed on the box body (2) and electrically connected with the electric heating element. A heating plate is arranged on the inner bottom of the box body (2). The heating plate consists of a framework (3), a heat transferring plate (5) fixed on the surface of the framework (3) and an electric heating element (4) fixed on the back of the heat transferring plate (5). The utility model not only has the advantages of simple structure, convenient use, high warming speed, uniform heat transferring, etc, but also overcomes the defects of traditional warmers, such as high energy consumption, easily oxidized heating elements, poor use safety, etc. The utility model provides a heating device suitable for broad families to use.
Description
Technical field: the utility model relates to a kind of heating installation, relates in particular to a kind of box warmer.
Background technology: electric heating device is the electric calorifie installation that people are used for warming, though it is of a great variety, function is different, but most of warmers all are to be heater element to be exposed to airborne resistance wire or quartz ampoule, not only oxidation easily, service life lack, but also have the hidden danger of leaking electricity and causing fire because of improper use.At present, though multiple box warmer with low temperature heater element in PTC potsherd, the MCH potsherd etc. has appearred on the market, but have defectives such as complex structure, cost height.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of heating case of simple in structure, safe and reliable, long service life.
To achieve these goals, the utility model by the following technical solutions: it comprises the uncovered casing in top, be arranged on heating in this casing, be fixed on the control device that is electrically connected with this heating on the described casing; Bottom in casing is provided with heating board, and this heating board is made of framework, the heat transfer plate that is fixed on this framework surface, the heating that is fixed on this heat transfer plate back side.
Respectively be provided with a heating board on two relative inwalls of casing; The surface of heat transfer plate fixedly is coated with woollen blanket; Heating is one of PTC heating sheet, MCH heating sheet or CTC heating sheet.
Compared with the prior art, the utility model is owing to adopted technique scheme, and substitute high temperature heater elements such as traditional resistance wire or quartz ampoule with low temperature heater element in PTC heating sheet, MCH heating sheet or the CTC heating sheet etc., therefore not only have simple in structure, easy to use, the advantage such as even that heats up rapidly, conducts heat, but also overcome traditional warmer energy consumption height, the easy oxidation of heater element, easily by defectives such as protection network scald, safety in utilization differences.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: control device 1 casing 2 frameworks 3 heatings 4 heat transfer plates 5 woollen blankets 6
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: heating board places the bottom of the uncovered casing in top 2, and described heating board is made of framework 3, the heat transfer plate 5 that is fixed on this framework surface, the heating 4 that is fixed on this heat transfer plate back side; The control device 1 that is provided with temperature control knob and power switch is fixed on the inwall of casing 2, and heating 4 is electrically connected with control device 1; Heating 4 can adopt PTC heating sheet, also can adopt MCH heating sheet or CTC heating sheet.In order to strengthen heating effect, on two of casing 2 relative inwalls, respectively be provided with a heating board; For fear of scald, fixedly be coated with woollen blanket 6 on the surface of each heat transfer plate 5.
