A cupboard 105 is installed above the sink 101, and a predetermined storage space is provided below the central area of the cupboard 105, and the wall-mounted microwave oven 111 is mounted in the storage space. have.

벽부착형 전자렌지(111)의 저면(113)에는, 도 6에서 확대하여 도시한 바와 같이, 한 쌍의 흡입구(115)가 형성되어 있으며, 흡입구(115)의 바깥측에는 각각 하나의 램프(117a, 117b)가 하향조명 가능하도록 설치 즉, 점등시 하부에 설치된 가스렌지(103)를 향하여 조명하여 적당한 조명도를 형성하도록 설치되어 있다.On the bottom surface 113 of the wall-mounted microwave oven 111, as shown in FIG. 6, a pair of suction ports 115 are formed, and one lamp 117a is provided on the outside of the suction port 115, respectively. , 117b is installed to enable downward illumination, that is, it is installed to illuminate toward the gas stove 103 installed at the bottom when the lamp is turned on, so as to form an appropriate illumination degree.

이러한 램프는 소정의 전원에 의해 점등되며, 그 점등회로가 도 7에 도시되어 있다.This lamp is turned on by a predetermined power supply, and its lighting circuit is shown in FIG.

도 7은 종래의 벽부착형 전자렌지의 램프점등회로도이다.7 is a lamp lighting circuit diagram of a conventional wall-mounted microwave oven.

종래의 램프점등회로는, 도면에 도시된 바와 같이, 한 쌍의 램프(117a, 117b)에 병렬로 연결되어 있는 램프전압원(121)과, 램프전압원(121)과 한 쌍의 램프(117a, 117b)사이에 연결된 고조명릴레이(123)와, 고조명릴레이(125)와 병렬로 램프전압원(121)과 램프(117a, 117b)사이에 직렬로 연결된 저조명릴레이(125) 및 다이오드(126)를 갖고 있다.In the conventional lamp lighting circuit, as shown in the figure, a lamp voltage source 121 connected in parallel to a pair of lamps 117a and 117b, a lamp voltage source 121 and a pair of lamps 117a and 117b. The low light relay 125 and the diode 126 connected in series between the lamp voltage source 121 and the lamps 117a and 117b in parallel with the high light relay 125 and the high light relay 123 connected therebetween.
