Description
Technical field
The utility model relates to the field that shielding reduces or eliminate the electric equipment electromagnetic radiation, especially a kind of irradiation eliminating apparatus that can electromagnetic radiation be shielded the non-radiation electromagnetic oven that absorbs and eliminate through the earth connection in the power supply.
Technical background
In recent years, electromagnetic oven has got into huge numbers of families because of its thermal efficiency height becomes the household electrical appliances rising star.Its operation principle is: convert AC power into direct current through rectifier; Make direct current become the high-frequency alternating current of 20-30KHZ through the RF power converter again; Again high-frequency alternating current is added on the electromagnetic induction coil of flat cored screw shape; Produce high-frequency alternating magnetic field thus; Its magnetic line of force penetrates the heat-resisting support panel of stove and accessory housing top setting and acts on the metal pan that is placed on this support panel, and at the metal bottom of pot body eddy current powerful because of electromagnetic induction produces, the internal resistance that eddy current overcomes the bottom of a pan produces thermal source.Electromagnetic oven work that is to say as long as just must have the substantial radiation source that the low frequency of high frequency and the 220V of 20-30KHZ is superimposed.The electromagnetic radiation meeting of electromagnetic oven causes adverse effect to people's cognition of close contact electromagnetic oven, and the research staff has proposed many technical schemes to solve electromagnetic radiation for this reason.For example; In the Chinese utility model patent specification of the CN2682767Y of on March 2nd, 2005 bulletin, disclose " a kind of electromagnetic oven ", its technical scheme comprises body of heater and platen, and platen is fixed on the body of heater; The body of heater surfaces coated is covered with metal coating, and the metal in the metal coating is a nickel alloy.The body of heater surfaces coated of the electromagnetic oven of this structure is covered with metal coating can only carry out the part magnetic screen to electromagnetic oven.
A kind of " radiation protection electromagentic furnace " disclosed in the Chinese utility model patent specification of the CN2777921Y of on May 3rd, 2006 bulletin; Comprise upper shell, lower house and panel; Characteristics are that the part beyond the relative stove interior loop of panel is provided with the metal radiation protective layer, and this metal radiation protective layer is located at the outer surface or the inner surface of panel; The inner surface of upper shell, lower house or outer surface are provided with the metal radiation protective layer; This metal radiation protective layer disclosed technical scheme in specification is: upper shell, lower house can directly adopt ferromagnetic material or composite material to make; Also can outside the plastic material housing, set up the cover body of a composite material; The heating position of the relative electromagnetic oven of cover body is provided with the cooker posting port, and the air entry and the exhaust outlet of lower house are provided with wire netting.Technical scheme adopts metal radiation protective layer electromagnetic radiation shielding with electromagnetic induction coil corresponding to the part beyond the panel heating position in the above-mentioned disclosed file; But the device of eliminating radiation is not set; And between this electromagnetic radiation shielding device panel and the housing, have the leakage field gap between panel and the pan, exist can not be effectively with ELECTROMAGNETIC RADIATION SHIELDING and the deficiency eliminated.
In on April 19th, 2006 disclosed Chinese invention patent ublic specification of application disclosed " a kind of skid resistant, antimagnetic leakage structure of electromagnetic oven "; In the disclosed technical scheme of this application be: include the electromagnetic oven main body; Cooking pan is seated on the support flat board of electromagnetic oven; The dull and stereotyped outer rim of support is embedded with ring-type skid resistant, antimagnetic leakage first quoit; Second quoit of ring-type antimagnetic leakage also is installed around the electromagnetic induction wire coil outer in the electromagnetic oven, and second quoit also is connected to a ground wire that draws outward.Can only electromagnetic induction coil be adopted the quoit radiation-screening corresponding to the part beyond the support flat board in the above-mentioned disclosed technical scheme; And the ground wire that on quoit, connects carries out magnetic radiation and releases; Ring-type skid resistant, antimagnetic leakage first quoit of the dull and stereotyped outer rim setting-in of support; Can further absorb the magnetic line of force, prevent that magnetic dispersion from taking place.But; Electromagnetic induction coil is the position that the magnetic line of force is the most intensive, electromagnetic radiation is the strongest corresponding to the pot body heated end portion on the support flat board; The magnetic line of force major part here can be by the pot bulk absorption; And a fraction of magnetic line of force causes electromagnetic radiation from the leakage field gap, to let out, so external electromagnetic radiation still exists because of between second quoit and the support flat board, have the leakage field gap between pot body and support flat board and first quoit.
In addition on June 1st, 2007; My application and " irradiation eliminating apparatus of the non-radiation electromagnetic oven " patent No. that obtains patent of invention are in the patent applications such as 200710109398.2; Though radiation provides a kind of shielding and cancellation element technology of complete closure to electromagnetic oven, exists the pot body to touch the incomplete problem in pad installation site.
