Description
Technical field
The utility model relates to shielding to be reduced or eliminates the field of electrical equipment electromagnetic radiation, especially a kind of shielding carried out the irradiation eliminating apparatus of the high-power non-radiation electromagnetic oven eliminated by power ground of high-power electromagnetic oven radiation being carried out being coupled.
Background technology
In recent years, high-power electromagnetic oven has progressively replaced liquefied gas, natural gas and oil burning installation to enter the large-scale dining units such as hotel, dining room with energy-efficient and advantage that is safety and environmental protection.But the operation principle of electromagnetic oven is that AC power is converted to direct current through rectifier, through frequency converter, direct current is become again the high-frequency alternating current of 20-30KHZ, again high-frequency alternating current is added on the spiral helicine electromagnetic induction coil of flat, hollow, produce high-frequency alternating magnetic field, its magnetic power makes to produce powerful eddy current because of electromagnetic induction bottom metal pan, and the internal resistance that eddy current overcomes the bottom of a pan produces thermal source.As long as that is substantial radiation source that is superimposed of the low frequency of the electromagnetic oven work high frequency and 50HZ that just must have 20-30KHZ.
The electromagnetic radiation of electromagnetic oven can cause adverse effect to the human body of close contact electromagnetic oven, and research staff proposes many technical schemes to solve electromagnetic radiation for this reason.Such as, on March 2nd, 2005 bulletin CN2682767Y Chinese utility model patent description in disclose " a kind of electromagnetic oven ", its technical scheme comprises body of heater and platen, and platen is fixed on body of heater, body of heater surface is coated with metal coating, and the metal in metal coating is nickel alloy.The body of heater surface of the electromagnetic oven of this structure is coated with metal coating and can only carries out part magnetic screen to electromagnetic oven.
In addition on June 1st, 2007, I applies for and the patent of invention of authorizing " irradiation eliminating apparatus of the non-radiation electromagnetic oven " patent No. is in 200710109398.2 patent applications such as grade, although provide a kind of shielding and cancellation element technology of complete closure to electromagnetic oven radiation, also lack the elimination radiotechnology of high-power electromagnetic oven.
Summary of the invention
In order to solve the radiation problem that leaks of high-power electromagnetic oven, the utility model provides a kind of screening arrangement having complete closure according to the design feature of existing band metal pan high-power electromagnetic oven, has electromagnetic radiation coupling circuit, can eliminate the irradiation eliminating apparatus of the high-power electromagnetic oven of electromagnetic oven radiation low-cost high-efficiency.Not only method is simple to utilize this technology, with low cost and to eliminate radiation effect good.
The utility model adopted technical scheme of dealing with problems is: a kind of irradiation eliminating apparatus with metal pan high-power electromagnetic oven, forms by according to exterior metal shell, metal pan, electromagnetic radiation coupler, electromagnetic conversion operating circuit and the power ground being assigned in one.Form a complete housing by metal shell, metal pan, electromagnetic conversion operating circuit and the electromagnetic radiation coupler of electromagnetic oven are loaded in housing, electromagnetic radiation coupler one end is connected with metal pan small resistor, the other end is connected with metal shell small resistor, power ground is connected with metal shell small resistor, the strong magnetic line of force that coil panel produces when electromagnetic oven works is except carrying out except eddy current thermal power transfer to metal pan, the radiation that metal pan also can be made to produce some leaks, these radiation leaked will be coupled on metal shell by electromagnetic radiation coupler, again together with metal shell shielding electromagnetic radiation by power ground be connected to the earth in eliminate, finally reach and eliminate electromagnetic oven and to leak the object of anti-radiation protection health.
Described metal shell is the shell adopting metal material processing shaping, and the relevant position perforate on shell leaves the position of installing metal pan.
Described metal pan is the matrix pot body directly adopting metal material processing.
Described electromagnetic radiation coupler can be that capacitor, resistor, resistance-capacitance coupling device etc. can the devices of coupled electromagnetic wave, also can be the one in a wire or the conductor material that is directly connected.
