Abstract
An electrodeless fluorescent lamp for a microwave oven comprises a microwave oven which comprises an oven body (1) which is provided with a magnetron and a waveguide, a control panel (2), an oven door (5) and a heating cavity (3), the bottom of which is provided with a rotary plate (4). The utility model is characterized in that the heating cavity (3) of the microwave oven is provided with a sealed electrodeless discharging lamp (6) which is filled with inert gas and mercury, and the wall of the electrodeless lamp is coated with phosphor (7). The utility model adopts the electrodeless fluorescent lamp in the microwave oven and uses the microwave oven as a high-frequency generating device of the electrodeless discharging lamp, having the advantages of lighting, long service life and disinfection effect.
Description
Technical field
The utility model belongs to a kind of illuminating lamp that uses on microwave oven.
Background technology
Electrodeless florescent lamp is to be coupled to high frequency radio wave in the discharge space that is filled with certain inert gas and mercury by certain measure, the electronics of discharge space vibrates back and forth in its residing position, make the mercury molecular ionization and excite, produce ultraviolet photon, these ultraviolet photons are got on the glass bulb inwall that is coated with fluorescent material, will produce visible radiation, electrodeless florescent lamp mainly is made up of the cell-shell that is filled with inert gas and a certain amount of mercury, radio-frequency generator, several parts of power coupling device.Microwave oven is to utilize microwave energy to make the hydrone motion in the food produce heat, convert electrical energy into the heat energy cooking food, tungsten filament illuminating lamp (because of tungsten filament is a metal) can not be installed in the service area of microwave oven, and the tungsten filament illuminating lamp can only be positioned in the nonclient area, and useful life is short.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of microwave oven electrodeless florescent lamp of long service life.
The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model is provided with microwave oven, microwave oven comprises body of heater (1), control panel (2), fire door (5), heating chamber (3), the heating chamber bottom is equipped with in rotating disk (4) body of heater magnetron, waveguide is housed, it is characterized in that: in microwave oven heating cavity (3), be provided with the sealing electrodless discharge fluorescent tube (6) that is filled with inert gas and mercury, scribble fluorescent material (7) on the electrodless discharge tube wall.
Magnetron in the utility model microwave oven body imports microwave by waveguide in heating chamber after, on the one hand the food in the heating chamber is heated, microwave signal excites the mercury molecular ionization in the electrodless discharge fluorescent tube on the one hand, produce ultraviolet ray, ultraviolet ray is got to and is promptly sent visible light on the phosphor powder layer of electrodless discharge tube wall and play illuminating effect.The electrodless discharge tube wall also can be provided with the local position that is not coated with fluorescent material, makes ultraviolet ray see through this position and enters heating chamber, and heating chamber is played the sterilizing effect.
The utility model is used for microwave oven with electrodeless florescent lamp, utilize the high frequency generating apparatus of microwave oven as electrodeless florescent lamp, make the electrodless discharge fluorescent tube send visible light and ultraviolet light, usually the illuminating lamp life-span in the microwave oven had only about 1000 hours, and can not be installed in the service area, the electrodeless florescent lamp life-span that the utility model is used for microwave oven can reach 60000 hours, and can be installed in the service area, electrodeless florescent lamp not only has illuminating effect, and its ultraviolet light also can play the sterilizing effect.

Specific embodiments
Present embodiment electrodless discharge fluorescent tube 6 is fixed on the interior sidewall of microwave oven heating cavity, be filled with inert gas and small amount of mercury in the fluorescent tube, half scribbles fluorescent material tube wall, half is not coated with fluorescent material, the part that is coated with fluorescent material is used for that the ultraviolet light in the fluorescent tube is become visible light and plays a role in lighting, and the position that is not coated with fluorescent material can make ultraviolet light see through heating chamber is played disinfective action.
Because the microwave of microwave oven is intermittently to send, present embodiment adopts two kinds of measures with assurance electrodless discharge fluorescent tube energy continuous firing, the one, and the fluorescent material of electrodless discharge fluorescent tube adopts long lad phosphor; The 2nd, reduce the fluorescent tube internal pressure, common electrodeless discharge lamp pipe pressure is 3-5 lattice oils column, the pressure of this routine electrodeless fluorescent tube is 1 lattice oil column, to guarantee the gas stable discharging in the fluorescent tube.
The effective quartz glass of this routine electrodeless discharge lamp is made, and quartz glass can see through ultraviolet light on the one hand, plays disinfective action, on the one hand the quartz glass long service life.
The electrodeless fluorescent tube of this example is a stock shape, also can be the sealing fluorescent tube of other shape that is filled with inert gas and mercury.
