[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a microwave oven internal light that illuminates the inside of a microwave oven that heats and cooks food and performs defrosting treatment by microwave irradiation from a magnetron.

[0002]

[Prior art]

 Inside the microwave oven, where food is cooked and thawed by microwave irradiation from a magnetron, an interior light is provided to illuminate the inside. Conventionally, a filament-type lamp has been used as the interior lamp of this microwave oven, and since this lamp has problems with electric wave leakage and wiring, punching holes are provided on the wall surface inside the microwave oven to perform punching. It is provided to illuminate the inside of the microwave oven through the hole.

However, in a structure in which the inside of the microwave oven is illuminated with a lamp through a punching hole provided on the inner wall of the microwave oven, the irradiation range of the lamp is narrowed by the punching hole, so the inside of the oven becomes dark. Moreover, since the light of the lamp is not natural light, the exact color of the illuminated food is not known and the cooking condition is not well understood. Furthermore, the structure in which a punching hole is provided on the inner wall of the refrigerator and the light is shined from there is more complicated to manufacture and costly. Moreover, since it is a lamp, wiring for power supply is also required, which is troublesome and costly.

Therefore, as a means for solving such inconvenience, the one disclosed in Japanese Patent Laid-Open No. 60-33427 has been proposed in the past, and as a means for solving the drawback, Japanese Patent Laid-Open No. 62-268085. And those disclosed in JP-A-63-116354. In all of these, an electrodeless discharge lamp that discharges and emits light by microwaves is installed in the microwave oven.

[0005]

[Problems to be solved by the device]

 However, in all conventional lamps, the lamp (fluorescent lamp) is directly exposed inside the microwave oven, so if the lamp breaks due to some accident, the lamp (fluorescent lamp) will be applied to the heated object in the control room. ) There is a problem that the fragments fall. In addition, since ordinary fluorescent lamps use mercury inside, they are dangerous when cracked against food.If they are directly exposed in the microwave oven, the container of the object to be heated may hit and crack. There is also a greater risk of incidents occurring.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a microwave oven interior lamp which solves the above-mentioned inconvenience.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a microwave oven in which microwaves are generated by a magnetron to heat and cook an object to be cooked, and a fluorescent lamp that is turned on by the radio wave output of the magnetron is provided in the microwave oven. The fluorescent lamp is characterized in that it is separated from the interior by a protective plate through which microwaves pass.

Further, the protective plate through which the microwaves pass is characterized by being transparent or translucent.

[0009]

[Action]

 Since the fluorescent lamp that lights up with the radio wave output of the magnetron is separated from the interior by a protective plate that allows microwaves to pass through, even if the fluorescent lamp breaks due to some accident, fragments may fall onto the object to be controlled. Absent.

Even if it is divided by the protective plate, the protective plate allows microwaves to pass therethrough, so there is no problem in cooking the cooked food and lighting the fluorescent lamp. Further, since the protective plate is transparent or semi-transparent, even if the fluorescent lamp is divided by the protective plate, it transmits light and can illuminate the interior.
