Description
Technical field
The present invention relates to temperature measuring equipment, specifically a kind of panel is combined by two or more cell block and is provided with the electromagnetic oven of temperature measuring equipment.
Background technology
The operation principle of existing electromagnetic oven utilizes the magnetic line of force in magnetic field by metalware (magnetic conduction is conductive material again) bottom, produces eddy current in metalware, makes metalware heating at a high speed voluntarily itself, and then the food in heating of metal vessel.
At present, on market, electromagnetic heating device is when temperature acquisition, all by whole piece insulating materials panel (ceramic panel, microcrystal face plate etc.) by metalware (magnetic conduction is conductive material again) bottom temp, pass on the temperature sensor in electromagnetic oven, calculation process is carried out again by the mainboard integrated circuit on electromagnetic oven, carry out power adjusting again, thus reach the temperature control requirement of needs.
Because metalware (magnetic conduction is conductive material again) bottom temp is by whole piece insulating materials panel (ceramic panel, microcrystal face plate etc.) to pass in electromagnetic oven on temperature sensor, because there is insulating materials panel (ceramic panel, microcrystal face plate etc.) existence, so, temperature in electromagnetic oven on temperature sensor can not be equal with the true temperature of metalware (magnetic conduction is conductive material again) bottom, it belongs to a kind of temperature radiation transfer mode, there is certain temperature value error between the two, the test of temperature value inaccuracy, cause the function that electromagnetic oven is not all cooked.
Also someone attempts boring a hole on insulating materials panel and installing temperature measuring equipment, but is limited to the material that existing panel applies, and there is the problem that stress is concentrated, and causes in transport, uses, easily broken in process, high in cost of production defect.
Summary of the invention
Technical problem to be solved by this invention overcomes above-mentioned existing electromagnetic oven to measure coarse defect to metalware bottom temp, provides a kind of and measure accurate electromagnetic oven to metalware bottom temp.
For this reason, the present invention adopts following technical scheme: a kind of electromagnetic oven, comprise electromagnetic oven panel, it is characterized in that, described electromagnetic oven panel comprises at least two cell blocks, be provided with heat-conducting piece between adjacent cell block, described heat-conducting piece directly contacts with at least one temperature sensor and carries out heat transfer.
When the present invention uses, be pressed on heat-conducting piece bottom metalware.Heat bottom metalware is directly passed to heat-conducting piece by the present invention, because temperature sensor directly contacts with heat-conducting piece, thermal loss is very little, thus making the temperature in electromagnetic oven on temperature sensor and the true temperature value bottom metalware (magnetic conduction is conductive material again) closely, the error between two temperatures reaches very little.Temperature sensor is connected with the coupler be arranged on integrated circuit mainboard by wire, carries out calculation process by the integrated circuit on mainboard, then carries out power adjusting, thus reaches the temperature control requirement of needs.
As improving further and supplementing technique scheme, the present invention takes following technical measures:
Described temperature sensor is arranged on a support, and described support is fixed on the housing of electromagnetic oven.
Support plays supporting and location effect to temperature sensor, and support can adopt elastic support or non-resilient support.
Described temperature sensor and heat-conducting piece close contact, thermometric more fast, accurately.
Described heat-conducting piece can be made up of Heat Conduction Material entirely; Also can make primarily of non-thermally conductive material, in non-thermally conductive material, be provided with heat conducting element or material, and the surface of heat conducting element or material and bottom surface exposed, the bottom surface of heat conducting element or material directly contacts with temperature sensor.
At least two described cell blocks are in the same plane, and heat-conducting piece surface exceeds cell block surface 0.5-5mm, and can make the bottom of metalware and heat-conducting piece surface contact so closely, thermometric is more accurate.
The material of described heat-conducting piece is ceramic panel or microcrystal face plate, also can adopt the high-temperature insulation panel of other materials.
The present invention adopts heat-conducting piece that the heat bottom metalware is almost passed to temperature sensor without loss, make the temperature in electromagnetic oven on temperature sensor and the true temperature value bottom metalware closely, error between two temperatures is very little, thus utilization can reach accurate control by the integrated circuit on mainboard to the temperature bottom metalware.
Below in conjunction with specification drawings and specific embodiments, the present invention is further illustrated.
