Abstract
The utility model relates to a constant temperature furnace, which comprises a base and a microcrystal glass panel, wherein the base is internally provided with an electric furnace and an electric circuit control board, an heat insulating board is disposed between the electric furnace and the electric circuit control board. The constant temperature furnace also comprises a sensor, wherein the sensor is located below the microcrystal glass panel, and the surface of the sensor is contacted with the lower surface of the microcrystal glass panel, thereby enabling the pan to keep constant temperature, not only avoiding electromagnetic radiation to hurt the human body, but also being suitable for various pans, and having wide range of use.
Description
Technical field:
The utility model relates to a kind of heater, relates in particular to a kind of constant temperature oven.
Background technology:
In the prior art, constant temperature oven mostly is the electromagnetic constant-temperature stove, there is following shortcoming in this constant temperature oven: the electromagnetic radiation that heater coil produces when work is harmful, and, the electromagnetism heating has special requirement to the pan material, can only be the irony pan promptly, make that the scope of application of this constant temperature oven is less.For this reason, people attempt again changing the heat generating member in the heater into electric furnace, though can avoid hazards of Electromagnetic Radiation like this, also can increase the scope of application of heater, and this heater can not carry out thermostatic control to pan again.
The utility model content:
The technical problems to be solved in the utility model is, provides a kind of and not only avoided hazards of Electromagnetic Radiation, but also can enlarge the constant temperature oven of the scope of application.
For solving above-mentioned technical problem, the utility model constant temperature oven, it comprises base and glass-ceramic panel, be provided with electric furnace and circuit control panel in the described base, be provided with thermal insulation board between described electric furnace and the circuit control panel, it also comprises sensor, and described sensor is positioned at the below of glass-ceramic panel, and the surface of described sensor contacts with the lower surface of glass-ceramic panel.
After adopting said structure, the utlity model has following advantage:
According to the vertical heat conduction of glass-ceramic panel, horizontal heat insulation characteristic, electric furnace by glass-ceramic panel to directly over pan heating, can be oppositely after pan is heated to the glass-ceramic panel heating outside directly over the electric furnace, the surface of sensor contacts the temperature that can record pan with the lower surface of this part glass-ceramic panel, when the temperature of pan reaches predetermined value, sensor is passed to circuit control panel with signal, circuit control panel cuts off the power supply to electric furnace, electric furnace stops heating, the temperature of pan begins to reduce, when temperature reduces a little and reaches predetermined value, the circuit control panel recovery is powered to electric furnace pan is heated, and so can make pan keep constant temperature, can avoid hazards of Electromagnetic Radiation, be applicable to various pans again, the scope of application is wider.
As improvement, described sensor and circuit control panel are positioned at the same side of thermal insulation board.Thermal insulation board separates sensor and electric furnace, thereby avoids the influence of electric furnace to sensor, makes sensor more accurate to the monitoring of pan temperature.
As further improvement, also scribble the heat-conducting silicone grease layer between the surface of described sensor and the lower surface of glass-ceramic panel.Like this, the heat transfer between sensor and the glass-ceramic panel is stable, sensor to the pan temperature monitoring more reliable.
As preferably, described electric furnace is a resistance furnace.
Improve as another kind, it also comprises sensor stand, and described sensor is installed on the sensor stand through spring.It is stable to use support to be convenient to sensor, and spring can make the contact of sensor contact with glass-ceramic panel or pan all the time, and the monitoring effect of sensor is better.

The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1 and Figure 2; the utility model constant temperature oven; it comprises base 1 and glass-ceramic panel 2; be provided with electric furnace 5 and circuit control panel 3 in the described base 1; electric furnace 5 is installed on the electric furnace installing plate in the base 1 on 9; the bottom of electric furnace 5 can also add shell fragment 10, can play a protective role to electric furnace 5 like this.Between electric furnace 5 and circuit control panel 3, be provided with thermal insulation board 6, electric furnace 5 and circuit control panel 3 can be separated like this.During use, pan 8 is placed on the glass-ceramic panel 2, and base 1 is placed on the operating desk by footing 11.
It also comprises sensor 4, and described sensor 4 is positioned at the below of glass-ceramic panel 2, and the surface of described sensor 4 contacts with the lower surface of glass-ceramic panel 2.Described sensor 4 and circuit control panel 3 are positioned at the same side of thermal insulation board 6, can avoid the influence of 5 pairs of sensors 4 of electric furnace like this.For the surface that makes sensor 4 contacts reliable and conducts heat stablely with the lower surface of glass-ceramic panel 2, between the lower surface of the contact of sensor 4 and glass-ceramic panel 4, also be provided with commercially available heat-conducting silicone grease layer 7.
Described electric furnace 5 can be selected resistance furnace for use.
It also comprises sensor stand 4.1, and described sensor 4 is installed on the sensor stand 4.1 through spring 4.2, and spring 4.2 supports sensor 4 and contacts with the lower surface of glass-ceramic panel 2 all the time.
According to general knowledge as can be known, generally indicate the mark of sensor 4 positions, and the bottom of pan 8 covers this mark when using at the upper surface of the glass-ceramic panel 2 of this constant temperature oven.
