상기 샤시(10)의 하단 주연부(11)와 디스챠지그릴(20)의 안착부(22)의 밀착부는 각형의 경사돌기(12)와 경사홈(23)으로 각각 형성하여 온도변화에 따른 팽창 및 수축시 항상 상호 밀착되도록 한다.The close contact portion of the lower periphery 11 of the chassis 10 and the seating portion 22 of the discharge grill 20 are each formed of a rectangular inclined protrusion 12 and an inclined groove 23 to expand and expand according to a temperature change. Always ensure close contact with each other when shrinking.

상기 각형의 경사돌기(12)와 경사홈(23)의 틈새는 약 0.5~0.8mm가 되도록 한다.The clearance between the inclined protrusions 12 and the inclined grooves 23 is about 0.5 to 0.8 mm.

이와 같이 구성된 본 발명은, 샤시(10)와 디스챠지그릴(20)의 조립시 디스챠지그릴(20)의 하단 주연부(21)에 설정된 간격마다 돌출형성된 다수의 안착부(22)를 샤시(10)의 하단 주연부(11)에 밀착되게 끼워 조립한다.According to the present invention configured as described above, when the chassis 10 and the discharge grill 20 are assembled, the chassis 10 includes a plurality of seating portions 22 protruding at intervals set at the lower periphery 21 of the discharge grill 20.
