이러한 구성에 의해서, 도어스크린(120)은 도어전면판(110)의 투시용개구(111)를 차단하도록 도어전면판(110)에 결합되어 전자렌지의 조리실 내부를 투시할 수 있도록 하고, 전자파차단판(130)은 도어스크린(120)의 후방에 배치되어 전자렌지의 조리실로부터의 전자파가 외부로 누출되지 못하도록 하며, 도어배면판(150)은 전자파차단판(130)의 공명실 입구(135)를 차단하도록 결합된다.By such a configuration, the door screen 120 is coupled to the door front plate 110 so as to block the see-through opening 111 of the door front plate 110 so as to see the inside of the cooking chamber of the microwave, and electromagnetic shielding The plate 130 is disposed at the rear of the door screen 120 to prevent electromagnetic waves from the cooking chamber of the microwave oven from leaking to the outside, and the door rear plate 150 is an resonance chamber inlet 135 of the electromagnetic wave blocking plate 130. Are combined to block them.

그런데, 이러한 종래의 전자렌지용 도어에 있어서는, 전자파가 유도되어 상쇄되는 공명실의 입구를 차단하기 위해서 도어배면판을 불가피하게 마련함으로써,부품추가에 따른 제작원가 상승과 작업공정 추가로 생산성을 저하시키는 문제점이 있다.However, in the conventional microwave oven door, the door back plate is inevitably provided in order to block the entrance of the resonance chamber in which electromagnetic waves are induced and canceled, thereby lowering productivity by increasing manufacturing costs and adding work processes due to the addition of parts. There is a problem.

이에 따라, 도어배면판을 이용하지 않고 공명실의 입구를 차단할 수 있다면, 부품을 절감할 수 있어 바람직할 것이다.Accordingly, if it is possible to block the entrance of the resonance chamber without using the door back plate, it would be desirable to save parts.

따라서, 본 발명의 목적은, 부품수를 줄여 제작원가 절감 및 생산성을 향상시킬 수 있는 전자레지용 도어를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a door for an electronic range that can reduce the number of parts and improve production cost and productivity.
