Abstract
The utility model relates to a two purpose electric heating disc, which belongs to an electric heating apparatus. The utility model is composed of a thermistor electrical heating element (PTC) with a positive temperature coefficient, a power cord, two current conducting radiating fins, an insulator, a base, a heat conducting plate, and an insulating piece. A presser foot is arranged below the heat conducting plate; the presser foot presses and fixes components of the electric heating disc after bended; the electrical heating element and the current conducting radiating fins are connected with current conducting gum. The utility model can automatically limit the highest heating temperature, and has the advantages of high safety, convenient installation, thin thickness, and high electric heating efficiency. The utility model can be widely used for heating and baking liquid, beverage, food, etc. in the occasions of families, offices, hotels, etc.
Description
The utility model relates to electric heating appliance, and more clearly saying so is in is used for the dual-purpose electric hot tray of heated baking that liquid, beverage, food and other article are heated or toast in the occasions such as front yard, office, laboratory.
The electric hot tray in past such as Electric stove etc. can not be controlled heating-up temperature mostly automatically.Because of temperature too high, easy scaling loss heating object, even catch fire and cause fire, very dangerous.When being used to toast, again Yin Wendu too high and easily burn, roasting stick with paste, roasting bad food or article, very undesirable.Except, the Electric stove in past is fixed by screw-nut mostly, and structure is complicated, and trouble slightly is installed, and cost is also high slightly.
The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provides a kind of and can limit maximum heating temperature automatically, can not burn out article, can not bake paste food, more can breaking out of fire, and safe and reliable; Can be used for heated baking ideally; And the dual-purpose electric hot tray of heated baking simple in structure, easy for installation, that cost is also lower.
In order to achieve the above object, the utility model is made of the base of electric heating element, the power line that links to each other with electric heating element, the insulator that electric heating element is installed, installation insulator.Said electric heating element is by semistor (PTC) and be close on the semistor two end electrodes two conduction fin and form.Power line links to each other with two conduction fin respectively.On the top conduction fin heat conduction utmost point is installed, lining is with insulating trip between the two.The resistance of semistor increases with the rising of temperature.And when temperature surpassed its Curie-point temperature, its resistance increased rapidly, and heating power then is reduced to almost nil rapidly.This just defines the maximum temperature of its heating.And the Curie point of this heating element is to select with different processing technologys.This just makes this electric hot tray can control maximum heating temperature automatically, guarantees to use safely and reliably, can not burn out article, can not bake paste, more can not cause fire, heats, toasts all very good.
Fixing below the heat-conducting plate and successively passing the presser feet that they is fixed and clamped after insulating trip, two conduction fin, insulators and the bases bending.This simple structure is simplified assembling, and cost also decreases.
Between semistor and two the conduction fin with conductive adhesive.This just makes the contact resistance between the two reduce greatly, and thermal conductivity improves, and electrothermal efficiency also improves.
Task of the present utility model comes to this and finishes.
The utility model can the volitional check maximum heating temperature, can the scaling loss article, the roasting food of sticking with paste, more can not cause fire, and heating, baking are dual-purpose, convenient, flexible, safe and reliable.It is simple in structure, easy to assembly, can be widely used in the places such as family, hospital, office, laboratory heating, baking to liquid, food and other article.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.
Fig. 1 is the structural representation of embodiment 1.
Shown in the figure, embodiment 1 is by being that PTC element 4, power line 7, insulator 5 and base 6 constitute with the semistor electric heating element.Two conduction fin 3 are close on the two end electrodes of PTC element 4, and with conductive adhesive.Power line 7 with rivet 9 riveteds the conduction fin 3 on.On the conduction fin 3 heat-conducting plate 1 is installed, lining is with mica insulation sheet 2 between the two.Be welded with 2 presser feets 10 below the heat-conducting plate 1, after presser feet 10 bendings insulating trip 2, conduction fin 3, insulator 5, base 6 all be assembled together together with PTC element 4, simple and practical.All be with porcelain ring 8 on power line 7 and the presser feet 10, insulate with thermal insulation.Embodiment 1 maximum heating temperature can be defined as 220 ℃ automatically.The heating, the baking all very good, can be widely used in the occasions such as family, hospital.
