Description

The photo-thermal electric oven

The utility model relates to the electric heater that utilizes the photoelectricity thermal source, is specially a kind of photo-thermal electric oven.

At present, the electric heater that people use always generally adopts quartzy infrared radiator.In the prior art, its primary structure all is in the space of housing and netted guard shield formation quartz ampoule to be housed, the pyrotoxin of the infrared radiator of this quartz-like all is open in the surface, be subjected to cargo sweat or collision to cause electric leakage and generation electric shock accidents easily, heat spreads easily during use, and it is inhomogeneous to dispel the heat, and heat insulation effect is poor, consuming electric power is big, and can not automatic switch.

The purpose of this utility model just is to overcome the deficiency of above-mentioned prior art, and heat radiation quick heating when a kind of use is provided can automatic switch limit temperature, refuse flare automatically, harm people body cell not, leakproof, the photo-thermal electric oven of high insulating effect.

The utility model is achieved in that the photo-thermal electric oven comprises body of heater, electro-heat equipment, automatic temperature limit switch, power line, the body of heater top is equipped with the heat sink of a double as cover plate, a thermal insulation board that has four circular holes is equipped with in the relevant position, top of body of heater, spacing equates between four circular holes on this thermal insulation board, the insulation base plate that has four holes corresponding with thermal insulation board also is equipped with in the bottom of body of heater, heat sink and thermal insulation board and body of heater form cavity, cavity is built-in with four equal-sized cylindrical tube metal furnace linings, metal furnace lining lower end is fixed on the thermal insulation board, circular hole is positioned at metal furnace lining central authorities, and the top is close to the heat sink bottom surface and is formed the heat build-up inner chamber; Electro-heat equipment is installed on the movable pressing board, and the circular hole that passes thermal insulation board from the hole of insulation on the base plate inserts metal furnace lining inner chamber corresponding site, and movable pressing board is fixed on the bottom surface of insulation base plate, and the band temperature limit switch of refusal flare device automatically is contained in the body of heater side; Electro-heat equipment is connected with automatic temperature limit switch by the electric wire series connection; Heat sink, metal furnace lining, thermal insulation board are made by the same metal material that scribbles fire prevention, heat transfer, intensification layer, and body of heater and insulation base plate are made by heat insulation, insulating materials.

After adopting such structure, because heat sink, thermal insulation board and insulation base plate and body of heater are totally enclosed type temperature storage, insulation, insulation system, thereby safe in utilization, can not have an accident because of reasons such as collision, corrosion cause electric leakage; And four electro-heat equipments stretch into the heating of metal furnace lining inner chamber, and heat removes and is directly transferred on the heat sink, can be transmitted to fast on the heat sink by the heat build-up of metal furnace lining inner chamber again, and programming rate is accelerated, and heat is more concentrated; The totally enclosed type keeping warmth space that forms in the body of heater makes heat can not spread again, dispels the heat evenly during use, and consuming electric power is few.In addition,, make the no flare generation in surface because heat sink, thermal insulation board and metal furnace lining surface scribble the heat transfer of band fireproof agent, the layer that heats up, can the harm people body cell yet; Again owing to adopted the automatically automatic temperature limit switch of refusal flare device of band is housed,, can play the function of closing automatically or opening when the people leaves or temperature when too high.

Introduce embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is a stereogram of the present utility model;
