Abstract

An electric fire box can be used for baking wetted shoes, insoles, clothings, quilts and the like, and also can be used for warming feet or a room. The electric fire box is characterized in that a heating board is arranged in a wooden box; batten grids are formed on the upper surface of the heating board and fixed together with wooden box; an adjustable temperature controlled switch is installed on the wooden box; one lead wire of the adjustable temperature controlled switch is connected with a live wire of a power supply, and the other lead wire in series connection with a fuse and a snap action temperature controller is connected to a live wire position of a 3-prong socket of the heating board; a zero wire position of the 3-prong socket is connected with a zero wire of the power supply; and an earthing wire position of the 3-prong socket is connected with an earthing wire of the power supply. Compared with a common electric warmer that heats through electric heating wires, the electric fire box only uses electrical quantity of 20 percent when generating the same heat quantity; the electric fire box does not generate electromagnetic radiation and static electricity to the outer surroundings when heating, cannot cause short circuit accidents when the surface meets water, and can also transmit far infrared rays at the same time so as to achieve health care and physiotherapy functions; and in addition, the electric fire box can heat uniformly and thermostatically.

Description

The electricity fire-box

Affiliated technical field

The utility model is a kind of shoes that wet that can be used for drying, shoe-pad, and clothing, quilt etc., and can be used for being applicable to the occasion that all need be warmed oneself to pin heating or to the electric fire-box of room heating.

Background technology

The heater members that existing space heater adopts all is a heating wire generally, and after the energising, the effect that produces heat is played in the just heating of the resistance of heating wire the inside.But the electrothermal wire heating has following deficiency: can produce electromagnetic radiation and static, if run into the water accident that can be short-circuited, and also electrothermal wire heating's poor effect, taking electricity, heating wire can not be accomplished even heating simultaneously.

Summary of the invention

At above-mentioned deficiency, the utility model provides a kind of electric fire-box, its adstante febre can externally not produce electromagnetic radiation and static, its surface runs into the water accident that also can not be short-circuited, it can also send far infrared, produces the health-care physical therapy effect, and its heating efficiency is 5 times of common electrical heated filament, and it can also accomplish evenly heated at constant temperature.

The purpose of this utility model is achieved in that coating nanometer carbon ink semiconductor exothermic material at the tow sides of a glass mat forms heating layer, stick again by insulating materials at the upper and lower surface of heating layer and (as to have soaked the glass fabric of epoxy resin, glass fibre, PET, mica, asbestos etc.) insulating barrier of making is a conductive layer in the outside of insulating barrier up and down, seven layers altogether of this plates have formed above-mentioned heating board by the high temperature pressing.Connect live wire onboard in addition, zero line, three sockets of earth connection.Through hole is arranged on glass mat, make up and down two-layer heating layer be communicated with, the live wire position of three sockets is by an in succession end of top heating layer of copper electrode, and the zero line position is by an in succession end of following heating layer of copper electrode, earth connection position in succession upper strata conductive layer and lower floor's conductive layer.

In wooden case, put this heating board, heating board is near the top of wooden case, on it, there are batten grid and wooden case to be fixed together, adjustable temperature detect switch (TDS) is housed on wooden case, the in succession live wire of power supply of a lead-out wire of adjustable temperature detect switch (TDS), connecting fuse and fast jumping formula temperature controller of another root lead-out wire is connected on the live wire position of three sockets, the in succession zero line of power supply of the zero line position of three sockets, the in succession earth connection of power supply of the earth connection position of three sockets, fuse and fast jumping formula temperature controller be attached to heating board below.

During use, plug in, electric current just comes out from the live wire of power supply, through adjustable temperature detect switch (TDS), fuse and fast jumping formula temperature controller have flowed to the other end from an end of top heating layer, down get back to zero line from the other end of following heating layer again, heating board just work has generated heat.In the heating layer heating, it also produces electromagnetic radiation, because the electric current direction of heating layer and following heating layer in the above is opposite, top heating layer and following heating layer almost be produced in same place big or small identical, the electromagnetic radiation that direction is opposite is so the electromagnetic radiation that they produce has just been cancelled out each other.Upper strata conductive layer and lower floor's conductive layer all are connected on the earth connection position of three sockets, the static that whole like this heating board produces just has been directed on the earth connection, simultaneously conductive layer can also armoured magnetic field, so whole heating board does not externally just produce electromagnetic radiation and static, this electric fire-box does not externally just have electromagnetic radiation and generation of static electricity thus.Nanometer carbon ink semiconductor exothermic material heating efficiency is 5 times of common electrical heated filament, and it can also send far infrared, produces the health-care physical therapy effect.Because nanometer carbon ink semiconductor exothermic material is in the middle of heating board, so the heating board surface runs into the water accident that also can not be short-circuited.Because the surface of whole heating board produces equal heat simultaneously, so this electric fire-box can be accomplished even heating.When temperature was higher than the temperature of fast jumping formula temperature controller setting, it is disconnecting circuit just, and heating board has not just generated heat, and when temperature was lower than the temperature of fast jumping formula temperature controller setting, it just connected circuit, and heating board has generated heat again, and electric fire-box keeps heated at constant temperature with this.

The beneficial effects of the utility model are: the electrothermal wire heating who adopts with the common electrical warmer compares, under the situation that produces equal heat, the utility model only need use 20% electric energy, energy-saving effect is very obvious, the utility model does not externally have electromagnetic radiation and generation of static electricity at adstante febre, the surface runs into the water accident that also can not be short-circuited, it can also send far infrared simultaneously, produce the health-care physical therapy effect, and it can also be accomplished evenly, heated at constant temperature is so the utility model has good result of use.
