The present invention relates to a wire length compensating device for an up and down grill of a ceiling type air conditioner and, specifically, to an elevating device for an up and down panel of a ceiling type air conditioner, which compensates for length deviation of a wire using a pulley, a pulley rotary shaft, and an elastic repulsive member in order for an up and down panel to be completely attached and connected to an inner unit main body having a filter which can be cleaned. According to the present invention, the elevating device for an up and down panel of a ceiling type air conditioner includes: the wire (1600) connected to the up and down panel (3000) by being wound on or unwound from multiple drums (1500) installed on a rotary shaft (1300) rotating by receiving the rotational force of a motor (1200) by being installed in a housing (1100) installed in the upper part of the inner unit main body (2000); and a wire length compensating unit compensating for the generation of length difference when the wire is wound on or unwound from the drum. The wire length compensating unit (1700) individually draws two strands of the wire wound on the drum and fixed to the housing at fixed intervals and discharges the two strands of the wire to an opposite side. When small tension is applied to the wire wound on the drum, the wire is supplied to the up and down panel by being drawn to the lower part, drawn to the upper part by the pulley (1750), and drawn to the lower part again by a load sensing pulley (1720). When the tension of the wire located between the drum and the load sensing pulley becomes bigger, the pulley moves down to the lower part while corresponding to an elastic repulsive force of the elastic repulsive member (1770) and controls a wound amount of the wire. Therefore, each corner of the up and down panel is attached to the inner unit main body.

    본 발명은 천장형 공기조화기의 승강그릴용 와이어길이보상장치에 관한 것으로서, 특히 청소가능한 필터를 내장하고 있는 승강패널이 실내기본체에 완전 밀착 결합되도록 와이어의 길이 편차를 도르레풀리와 도르레풀리회전축 및 탄발부재에 의해 보상해 주도록 된 천장형 공기조화기용 승강패널승하강장치에 관한 것이다. 본 발명의 천장형 공기조화기용 승강패널승하강장치는, 실내기본체(2000)의 상부에 구비된 하우징(1100)에 설치되어 모터(1200)의 회전력을 전달받아 회전하는 회전축(1300)에 설치된 복수개의 드럼(1500)으로 풀리거나 감기면서 승강패널(3000)에 연결되도록 된 와이어(1600)와, 와이어가 드럼에 감기고 풀릴 때 길이의 차이가 발생하는 것을 보상하도록 된 와이어길이보상유니트를 갖추되, 와이어길이보상유니트(1700)는, 하우징에 고정됨과 더불어 드럼에 감긴 2가닥의 와이어가 각각 일정한 간격으로 유입되어 반대쪽으로 배출되되, 드럼에 감긴 와이어에 장력이 적게 걸리면 와이어가 하부로 유입되어 도르레풀리(1750)에 의해 상부로 올라갔다가 다시 하중감지풀리(1720)에 의해 하부로 내려와서 승강패널로 공급되며, 드럼과 하중감지롤러의 사이에 위치한 와이어의 장력이 커지게 되면 도르레풀리가 탄발부재(1770)의 탄발력에 대향하여 하부로 내려오면서 와이어의 감김량을 조절하여 승강패널이 각각의 모서리가 실내기본체에 밀착되도록 된 것을 특징으로 한다.
