Abstract
The utility model relates to an electric heating energy-saving warmer, which takes PTC sensitive ceramics as an electrical heating element. An outer casing is composed of a heating plate and a base; an electric heating box is arranged in the outer casing; after a power supply is switched on; the electrical heating element in the electric heating box transfers the heat of the electrical heating element to the heating plate via a heat transferring plate for heating. The utility model is especially suitable for people putting feet on the heating plate for the heating when working and studying at a table. The utility model has fast rise in temperature, less power combustion and long service life.
Description
A kind of employed electrothermal energy-saving warmer of electricity field that relates to.
Use at present the infra-red heater of heating in the quartz ampoule or the heating board of far ultrared paint, they all with the metallic resistance silk as heater element, its weak point is that electric power consumption is bigger, heating wire uses with the passing of time yielding.
The purpose of this utility model is intended at the problems referred to above and actual needs, and a kind of electrothermal energy-saving warmer is provided.Be particularly useful for using for when study of bending over one's desk working.
The purpose of this utility model is to realize like this, adopt the PTC sensitive ceramic as heating, its concrete structure is formed shell body by heated sheet and base, in be provided with Electric heating box, the Electric heating box circumscripted power line, Electric heating box is formed box body by heat transfer plate and base plate, be built-in with sensitive ceramic, electrode and insulator, power line communicates with electrode respectively, and Electric heating box is supported by the spring that installs on the base, make heat transfer plate and heated sheet keep being close to, after electricity was connected, the heat of sensitive ceramic was passed to heated sheet by heat transfer plate, and used for heating, when it was particularly useful for bending over one's desk working study, foot-operated being placed on the heated sheet warmed oneself.
The utility model adopts the PTC sensitive ceramic as heating, has following advantage:
1, electric power consumption is few, and maximum power consumption only is 40W/h, and is not subjected to the influence of mains voltage variations, and alterating and direct current all can be used.Because different sensitive ceramics has different Curie-point temperatures, therefore,, can obtain the inferior heating temperature of different retainings along with the difference of selecting ceramic material sensitive to heat-humidity for use.
2, when power connection, the resistance value of sensitive ceramic is low during than normal temperature, and then starting current is big moment, thereby has and heat up rapidly.
When 3, sensitive ceramic is worked, its resistance value can be with the increase and decrease of temperature respective change, thereby the utility model can remain constant relatively heating temperature, can not transship during thermal sensitive ceramics work, have long service life, its continuous operation life-span can reach 5000 hours.
Fig. 1 is a structural representation of the present utility model.
Embodiment: as shown in Figure 1, heated sheet 1, heat transfer plate 4, base plate 5 usefulness aluminum materials are by the mould drawing, base 2 is through heat ductile forming, between heat transfer plate 4 and base plate 5, be equipped with sensitive ceramic 6, the upper and lower limit of sensitive ceramic 6 is furnished with electrode 7,8 and mica insulator 9,10 respectively, electrode 7,8 circumscripted power lines 3, spring 11 places the base upper support Electric heating box, and heated sheet 1 and base 2 are used screw attachment.
