Description

A kind of infrared cooking equipment
Technical field
The present invention relates to a kind of infrared cooking equipment, belong to the heat-insulated field of heating vessel.
Background technology
At present, existing cooking equipment, such as baking machine are all added using resistance heating wire or electrothermal tube The structure of heat.It is typically to be set between resistance heating wire or electrothermal tube and housing to reduce thermal loss Heat-preservation cotton is put, but the effect of heat insulation of heat-preservation cotton is poor, and larger heat causes amount of heat to shell diffusion Loss, it is uneven also to there is heating in the structure for causing to consume energy greatly and using resistance heating wire or electrothermal tube to heat And the big shortcoming of structure space.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of infrared cooking equipment, overcome in the prior art Insulation is that, by setting heat-preservation cotton between resistance heating wire or electrothermal tube and housing, structure heating is uneven Even, consume energy the big and big defect of structure space.
The technical scheme that the present invention solves above-mentioned technical problem is as follows:A kind of infrared cooking equipment, including pottery Outside the cooking ware that porcelain is made and the bearing for supporting the cooking ware, the bottom wall of the cooking ware Surface attachment has Electric radiant Heating Film;Suction is provided between the bottom wall outer surface of the cooking ware and the Electric radiant Heating Film Receive the heat-sink shell of the electrothermal film radiation heat.
The beneficial effects of the invention are as follows:The present invention due to the bottom wall outer surface of cooking ware and Electric radiant Heating Film it Between be provided with the heat-sink shell for absorbing electrothermal film radiation heat, the heat-sink shell can absorb electrothermal film radiation heat Heat transference efficiency is improved simultaneously, is accelerated the heat transfer to cooking ware, is reached good heat-transfer effect, and The structure more fastens durable.
On the basis of above-mentioned technical proposal, the present invention can also do following improvement.
Infrared cooking equipment as described above of the invention, further, the cooking ware and the heat-sink shell It is made by black ceramic, the heat-sink shell is integrally formed with the cooking ware.
It is using above-mentioned further beneficial effect:Said structure of the present invention is to realize cooking ware and heat absorption Layer one is made up of black ceramic, and the cooking ware can absorb the radiant heat of Electric radiant Heating Film in itself, effectively carry The programming rate of temperature in high vessel, reduces thermal loss.
Infrared cooking equipment as described above of the invention, further, the heat-sink shell is black high temp resistance Coating, it is therefore preferable to black chrome coating or black nickel coating.The black high temp resistance coating can be resistant to 400 degree with On high temperature.
It is using above-mentioned further beneficial effect:Institute is adapted to using black chrome coating or black nickel coating There is the pottery of type and make a concerted effort by force with ceramic junction.
Infrared cooking equipment of the invention as described above, further, the thickness of the heat-sink shell for 200~ 500μm。
Invention infrared cooking equipment as described above, further, open at one end is limited on the bearing, The host cavity of other end closing, the cooking ware is arranged on the opening end of the host cavity, the collecting There is gap between the bottom wall of the inner face of the blind end of chamber and the cooking ware.
It is using above-mentioned further beneficial effect:Because the inner face of the blind end of host cavity is cooked with described Preparing food has gap between the bottom wall of vessel, and the gap can be used for radiating, prevent the blind end of host cavity Inner face temperature is too high, that is, prevents that the bottom wall temperature of bearing is too high.
