Abstract

The utility model provides a novel electric-heating transparent bread toaster, in particular to a full transparent electric-heating bread toaster, whose heating elements are transparent conductive films. The utility model has the advantages of simple structure, beautiful appearance, high heating efficiency, and uniform toasting temperature, which is an ideal household electric-heating device with commodity value.

Description

Transparent bread toaster

The utility model relates to a kind of electrothermal bake bread device of novelty, is specifically related to a kind of transparent conductive film electrical heating type bake bread device.

Popular in the market bake bread device all is the bake bread device based on Electric heating, and its thermal element generally has two kinds: a kind of single or double heating sheet for the heating wire winding; Another kind is embedded tubular electrothermal element.These two kinds of electric heaters all are to be heater element with the nichrome wire, and part energy consumes with the visible light form in its heating process, so the thermal efficiency reduces relatively; And the also easily oxidation in air of the heating wire of naked form, for roaster, this heating heating is inhomogeneous, and bigger thermograde is arranged.Therefore, as the bake bread utensil of heater element above-mentioned certain defective is arranged with nichrome wire with this.

The purpose of this utility model provides a kind of simple in structure, the thermal efficiency is high, baking quality is good and aesthetic in appearance bake bread device.

For achieving the above object, the utility model spy provides a kind of electrothermal bake bread device, and it mainly comprises a base; One has the housing of some rusk heating chambers that are parallel to each other; The heating of the sidewall of some formation heating chambers; The rusk carriage of one suspension between all heating chambers and housing bottom; One can be with the device for ejecting that pushes away on the carriage or transfer; Two relatively be fixedly set in the both sides of carriage respectively, when carriage moves up and down, guide the guiding mechanism of its direction, and a temperature controller.It is characterized in that described heating is made up of transparent conductive film and some electrodes that is coated on the conductive film that a transparent base, is coated on the described transparent base.

Above-mentioned electrothermal bake bread device owing to adopt transparent conductive film as heater element, does not have the energy consumption of visible light form, so thermal efficiency height in its heating process.In addition, because transparent conductive film is planar heating, so temperature is even, baking efficient height, the flames of anger; And it is simple in structure, and is aesthetic in appearance, and whole clearing can directly be observed cured effect.

Below by introduction and description of drawings thereof, can further understand the purpose of this utility model, structure and advantage to the utility model embodiment.Its accompanying drawing is:

Fig. 1 is the perspective view of the utility model one embodiment;

Fig. 2 is the elevational cross-sectional view along " A-A " line among Fig. 1; And

Fig. 3 is the cutaway view along " B-B " line among Fig. 2.

Shown in Fig. 1,2 and 3, the chief component of the utility model electrothermal bake bread device includes:

One base 5;

One shell 2, it has the rusk heating chamber 10 that some (being 3 in the present embodiment) are parallel to each other, and this shell can be made by transparent glass or resin;

Be arranged on the heating 1 of each heating chamber both sides, each heating 1 is made up of transparent base 111, the transparent conductive film 112 and the some electrodes 113 that is fixed on the conductive film 112 that are coated on this transparent base.In the present embodiment, transparent base 111 usefulness transparent high temperature resistant glass are made, and are bonded on the shell 2; Transparent conductive film 112 can utilize chemical vapour deposition (CVD) or magnetron sputtering technique and be coated on the transparent base 111, be added with in the gas source of vapour deposition or in the sputtering target material during coating some doped chemicals (referring to by Shanghai Silicate Inst., Chinese Academy of Sciences in application on July 31st, 1992, application number is the patent of invention " electric heater of transparent conductive and the application thereof of long-term work under high temperature " of CN92109071.4); And respectively establish an electrode 113(at relative two ends of each conductive film 112 and consult Fig. 3), this kind electrode is single or compound metal electrode (as the Ni-Cr electrode), adopts vacuum deposition method to be coated on the conductive film 112;

One rusk carriage 9 is made with stainless steel or other material, and its suspension is between the bottom of all heating chambers 10 and housing 2, in order to hold all rusk of putting into from heating chamber 10;

One device for ejecting 4, it is arranged under the carriage 9, is operatively connected relation with carriage, when above-mentioned carriage 9 is transferred, rusk 7 is all descended put in place; When the rusk baking finishes; The rusk that this device for ejecting will be baked carriage 9 ejects heating chamber;

Two guiders 6 relatively are fixedly set in the both sides of above-mentioned carriage 9 respectively, are used for guiding when the upper and lower motion of carriage its direction; And

One temperature controller 3, it is temperature required to be used for regulating the baking rusk, treat that temperature reaches after, the mechanical organ of establishing by other impels above-mentioned device for ejecting 4 that carriage 9 is popped up, to eject roasting good rusk.

This shows, the thermal efficiency height of conductive film type heating of the present utility model, temperature is even, and cured effect is good, and advantages such as the flames of anger are tangible.Through probationary certificate, the utility model electrothermal bake bread device can be worked under operating temperature (＜220 ℃) steadily in the long term, and because whole housing is transparent, the baking live telecast of the rusk of dress in can directly seeing, have much appreciation effect on the spot, real is the roasting equipment of a kind of tame electricity consumption that is suitable for promoting.

The utility model is not limited to above-mentioned appearance structure shown in the drawings, can adopt different base materials according to different needs, and different electrodes is made the bright bake bread device of full impregnated of various different geometries and different structure.
