Abstract
The utility model discloses an electrothermal cooking vessel, concretely an electrothermal furnace, comprising a sheet with a depressed area, a heating element in the depressed area and a cast iron panel arranged on the upper surface of the shell and at least covering the depressed area, characterized in that: the heating element comprises an adiabatic and insulated base seat and a thermal resistance wire fixed on the base seat, wherein the thermal resistance wire does not contact with the cast iron panel. The thermal resistance wire heats the cast iron panel using thermal conduction and thermal radiation ways and the heating speed is quicker. The base seat for fixing the thermal resistance wire is not only insulated but also adiabatic and the air heat storage coefficient is relative small. Thus the residual heat in the electrothermal furnace is relative small to increase the cooling rate of the iron cast panel by a certain degree after the thermal resistance wire stops work. In addition, the utility model also discloses an oven with the electrothermal furnace.
Description
Technical field
The utility model relates to the electrical heating cooking apparatus, specifically is a kind of electrothermal furnace and the baking box with this electrothermal furnace.
Background technology
Existing panel type cooking furnace has electromagnetic oven, electric pottery stove and electrothermal furnace etc., although the operation principle of these stove and accessorys and mode of heating are all inequality, the cooker loading end all is a panel.Wherein electromagnetic oven and electric pottery stove often adopt glass-ceramic panel as loading end, and electrothermal furnace cast iron panel then commonly used is as loading end.
Electrothermal furnace generally includes: have sunk area housing, be arranged on heater element in the housing sunk area, be arranged on above the housing and cover the cast iron panel of its sunk area at least.Wherein, heater element comprises insulating materials and is embedded in heating resistance wire in the insulating materials fully.For improving the efficiency of heating surface, the lower surface of cast iron panel is close to the upper surface of insulating materials.During work, the direct heat packs of heating resistance wire is covered insulating materials thereon, and insulating materials conducts the cast iron panel that heats on it by heat more then.
The weak point of this electrothermal furnace is:
On the one hand, the heat ray penetrance of general insulating materials is extremely low, so the heat of the heating resistance wire of traditional electrothermal furnace is to pass to the cast iron panel by insulating materials in the mode of heat transmission.Even therefore heating resistance wire quits work, heat-insulating material still stores certain heat, causes the cast iron panel to need the long period to lower the temperature.So not only can cause waste to the energy, it is high and it is carried out operations such as wiping, touch to make the user take for cast iron panel temperature as carrying cooker face easily after electrothermal furnace quits work a period of time yet, and causes the scald accident thus.In addition, because heating resistance wire is by heat exchange pattern heating cast iron panel, so electrothermal furnace needs the long period cast iron panel could be heated to operating temperature after starting working, and it is slower promptly to heat reaction speed, has reduced user's experience.
On the other hand, for general insulating materials, its heat resisting temperature is lower, therefore can not use the bigger heating resistance wire of power, has limited the raising of the operating temperature of electrothermal furnace.
The utility model content
First technical problem that the utility model solves provides a kind of electrothermal furnace, and not only firing rate is fast to make it, and cooling rate is also very fast.
Second technical problem that the utility model solves provides a kind of baking box of above-mentioned electrothermal furnace, makes this baking box further possess the function of electrothermal furnace, realizes the multifunction of baking box.
For solving first technical problem, first technical scheme that the utility model adopts is:
A kind of electrothermal furnace, comprise: have sunk area housing, be arranged on heater element in the housing sunk area, be arranged on above the housing and cover the cast iron panel of its sunk area at least, it is characterized in that: described heater element comprises the pedestal and the heating resistance wire that is installed on this pedestal of thermal insulation and insulation, and this heating resistance wire does not contact with described cast iron panel.
As one of improvement of the present utility model: be spaced apart 2 to 11mm between described heating resistance wire and the described cast iron panel.Meeting under the prerequisite of electric safety standard, if the distance between heating resistance wire and the cast iron panel is enough little, then the firing rate of electrothermal furnace can be faster, and after stopping heating, the heat that remains in air buffer is also less, can very fast conduction gives the cast iron panel and distributes.
As two of improvement of the present utility model: described heating resistance wire is long ribbon shape, and its lower end is plugged in the described pedestal.
As three of improvement of the present utility model: state heating resistance wire and be long ribbon shape, its lower end is plugged in the described pedestal.
As four of improvement of the present utility model: the lower end of described heating resistance wire distributes to be provided with and is used for plugging the some protuberances that are fixed on described pedestal.
As five of improvement of the present utility model: the upper end of described heating resistance wire also is provided with and its protuberance corresponding concave part.
As six of improvement of the present utility model: also be provided with fixing hole on the described protuberance, be equipped with the fixed leg that protrudes in the protuberance surface in the described fixing hole.
For solving second technical problem, second technical scheme that the utility model adopts is:
A kind of baking box comprises the baking box main body, it is characterized in that: the upper surface of described baking box main body also is installed with described first technical scheme or the described electrothermal furnace of its improvement project.
Compared with prior art, the beneficial effect of the utility model first technical scheme is: because described heating resistance wire is barish, only conduct mode of heating compared to original by heat, the utility model is by the heat conduction and the heat radiation dual mode heating cast iron panel of air buffer, and the speed of heating is faster.And the pedestal that is used for fixing heating resistance wire not only insulate, but also adiabatic, thus pedestal can't to store the heat of heat or storage minimum.Because the heat accumulation coefficient of air is less, the heat that the air buffer in the electrothermal furnace stores is also very little in addition.Therefore the cooling rate of cast iron panel after heating resistance wire quits work obtains raising to a certain degree.
