Background technology
At present, at cooked wheaten food making, tobacco processing course, all need to use apparatus for baking, its electrical heating elements mostly is the electrothermal tube that heating alloy constitutes, and heating alloy is the line heat source of high temperature naked light heating, and its thermal hysteresis is serious, electric conversion efficiency is low, and starting current is big, and the life-span is short.The apparatus for baking that uses infrared heating is arranged in the recent period,, make body of heater by double-deck skeleton as Chinese patent " ZL86210479.3 far infrared food baking oven ", riveted joint has reflecting plate around the inner frame, austenic stainless steel belt is installed on the electric hot plate with cleat insulator, is placed in the burner hearth, the surface scribbles Fe
3O
4, Fe
2O
3Oxide layer, as the heater element that heats up.Emitting far-infrared because of it, have the advantage of economize on electricity, clean environment, advanced technology, be applied.Along with the continuous appearance of new technology, the far infrared thermal source needs more easy structure.
The face electric hot plate of existing a kind of insulating substrate surface modification is made base material by the carborundum plate of thickness 4-6mm, and surface modification is made, and its thermal efficiency is up to more than 96%, and thermal inertia is little, and radiating surface is big, and quick heating is more fast again than heating alloy temperature rise; Long service life, but continuous operation up to ten thousand hours; Face electric hot plate radiation wavelength is at the infrared waves of 5-14 micron, and the organic nutrition composition of baked goods is damaged seldom, and it is light to have structure, is convenient to the advantage of making the electric heating thermal source of apparatus for baking preferably is installed.
Summary of the invention
The purpose of this utility model is, design and produce a kind of far infrared surface electric radiation apparatus for baking, adopt the face electric hot plate of insulating substrate surface modification to make pyrotoxin, be arranged on the inside panel of apparatus for baking, it is light to constitute structure, quick heating, easy constant temperature, the apparatus for baking of article such as long-lived baked goods or tobacco.
The technical scheme that the utility model adopted is, a kind of far infrared surface electric radiation apparatus for baking, by roof box, exterior panel, inside panel, base plate, heat reflection plate is formed, fill insulant material between exterior panel and inside panel, top board is equipped with temperature controller, inside panel is a heat reflection plate, be fixed with the face electric hot plate of the insulating substrate surface modification of queueing discipline on inside panel and the base plate, blocked protection network on the face electric hot plate, the end edge of every block of insulating substrate surface modification face electric hot plate is along being provided with silver electrode and electrode terminal, and contact conductor is connection in series-parallel and is connected with electric-controlled switch; Establish electric-controlled switch in the exterior panel side, casing is provided with the cabinet door of fill insulant material.
The utility model has the advantages that: the electric heating conversion superior function of giving full play to existing face electric hot plate, compare with existing like product, energy-saving effect is obvious, the thermal efficiency of the face electric hot plate that is adopted is up to more than 96%, quick heating, changed resistance wire heating hysteresis, be easy to control temperature, the safety during the equipment that guaranteed is used; But continuous operation up to ten thousand hours; Face electric hot plate radiation wavelength is at the infrared waves of 5-14 micron, can activate in the biological cell can, protect its organic nutrition composition, the organic nutrition composition of baked good such as pollen, tobacco, vegetables, seed is damaged seldom; Safe in utilization, durable.Be applicable to the apparatus for baking of article such as various baked goods or tobacco.
Description of drawings
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the vertical organigram of far infrared surface electric radiation apparatus for baking of the present utility model
Fig. 2 is the A-A profile of Fig. 1
Among the figure, 1-exterior panel, 2-inside panel (heat reflection plate), 3-insulation material, 4-temperature controller, the face electric hot plate of 5-inwall, the face electric hot plate of 6-base plate, 7-protection network, 8-cabinet door, 9-silver electrode, 10-contact conductor, 11-electric-controlled switch.
The specific embodiment
As seen from Figure 1, far infrared surface electric radiation apparatus for baking of the present utility model, by roof box, exterior panel, inside panel, base plate, heat reflection plate is formed, fill insulant material 3 between exterior panel 1 and inside panel 2, top board is equipped with temperature controller 4, inside panel is a heat reflection plate 2, be fixed with the face electric hot plate 5 of the insulating substrate surface modification of queueing discipline on the inside panel, also be fixed with the face electric hot plate 6 of the insulating substrate surface modification of queueing discipline on the base plate, blocked protection network 7 on the face electric hot plate, establish electric-controlled switch in the exterior panel side, casing is provided with the cabinet door 8 of fill insulant material.
As seen from Figure 2, the end edge of every block of insulating substrate surface modification face electric hot plate is along being provided with silver electrode 9 and electrode terminal, and contact conductor 10 is connection in series-parallel and is connected with electric-controlled switch 11;
Using method of the present utility model is: the desire baked good of packing in the far infrared surface electric radiation apparatus for baking, connect power supply, the heating of face electric hot plate, radiated infrared ripple, air heat, temperature near the face electric hot plate be can be adjusted to preference temperature, can reach the baking purpose.
