Hereinafter, an elevating and lowering device for a ceiling-mounted air conditioner according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the drawings, the same reference numerals are given to the same elements even when they are shown in different drawings. In the drawings, the same reference numerals as used in the accompanying drawings are used to designate the same or similar elements. And detailed description of the configuration will be omitted. Also, directional terms such as "top", "bottom", "front", "back", "front", "forward", "rear", etc. are used in connection with the orientation of the disclosed drawing (s). Since the elements of the embodiments of the present invention can be positioned in various orientations, the directional terminology is used for illustrative purposes, not limitation.

1 and 2, a ceiling-mounted air conditioner lifting apparatus 1000 according to an embodiment of the present invention is installed in a housing 1100 provided at an upper portion of an indoor unit body 2000 A rotation shaft 1300 that is rotated by receiving the rotational force of the motor 1200; a rotation sensor 1400 installed on the rotation shaft to sense a rotation angle; a plurality of drums 1500 provided on the rotation shaft; And a wire length compensating unit 1700 for compensating a difference in length when the wire is wound and unwound from the drum.

As shown in FIGS. 2 to 11, the wire length compensating unit 1700 includes a plurality of wires 1600 wound around the drum 1500 at regular intervals to be discharged to opposite sides of the drum 1500, The wound wire 1600 is introduced into the lower part and is raised by the pulley 1750 and then lowered by the load sensing pulley 1720 to be supplied to the lifting panel 3000 while the drum 1500 When the tension of the wire 1600 located between the load detection rollers 1720 is increased, the pulley 1750 descends downward against the elastic force of the elastic member 1770, So that the respective corners of the lifting panel 3000 are brought into close contact with the indoor unit body 2000.

Accordingly, the length variation of the wire 1600 can be compensated for so that the lifting panel 3000 having the filter capable of cleaning can be completely and tightly coupled to the indoor unit body 2000. Thus, the length- 3000 are made to be in a state in which they can be brought into close contact with the indoor base frame 2000 without hitting the four corners thereof.

Hereinafter, the wire length compensating unit 1700 will be described in more detail. The wire length compensating unit 1700 includes a pulley accommodating member 1710, a load sensing pulley 1720, a load sensing pulley rotary shaft 1730, a micro limit switch 1740, A pulley 1750, a pulley pulley rotary shaft 1760, a resilient member 1770, and a cover 1780.

The drum accommodating member 1710 is mounted on the housing 1100 and has grooves 1600 formed at regular intervals to allow the two wires 1600 wound on the drum 1500 to flow in at regular intervals to be discharged to the opposite sides A guide groove 1713 formed at a predetermined distance from the upper portion of the groove so as to fit the rotary shaft of the guide pulley in a direction perpendicular to the groove, A covering member fixing groove 1714 formed to be deeper than the guide pulley rotation axis guide groove to elastically support both ends of a rotary pulley rotary shaft inserted along the guide pulley rotary shaft guide groove and a cover fixing portion 1715 formed in a screw shape on the upper surface, And a switch fixing portion 1716 protruding from both sides.

Thus, the load sensing pulley 1730 and the pulley rotation shaft 1760 are fitted into the groove 1711 so that the load sensing pulley 1720 and the pulley 1750 are positioned.

Further, the rotation of the load sensing pulley rotary shaft 1730 may be raised to a certain height by the slot 1712, and the slot may be formed to be long.

The load sensing pulley 1720 is formed with a groove for guiding the wire to the outer circumferential surface and is fitted to the load sensing pulley rotary shaft 1730 so as to be positioned in each groove 1711 of the toothless accommodating member 1710.

The load sensing pulley rotary shaft 1730 is inserted into the elongated hole 1712 so as to protrude from both sides of the pulley accommodating member and is inserted into the center of rotation of the load sensing pulley 1720.

Accordingly, when the wire 1600 is caught by the load sensing pulley 1720 and the tension is applied in the upward direction, the load sensing pulley rotary shaft 1730 contacts the micro limit switch 1740, .

When the load sensing pulley rotation shaft 1730 rises, the micro limit switch 1740 senses the rising of the load sensing pulley rotation shaft and sends a motor operation signal to a control unit not shown. When the rotation sensing shaft of the load sensing pulley 1740 rises It is detected and fixed to the switch fixing portion 1716 to stop the operation of the motor by sending a control signal to the control portion.

The pulley 1750 is fitted in the groove 1711 of the pulley housing member 1710 and is positioned between the drum 1500 and the load sensing pulley 1720 Respectively.

Therefore, when the tensile force applied to the pulley 1750 by the pulley 1760 is increased, pressing the pulley 1770, which is a compression spring, causes the pulley 1760 to rotate downward along with the pulley rotation axis 1760 in the groove of the pulley accommodating member. At this time, the length of the wire 1600 is finely corrected so that the edge of the lifting panel 3000 is closely attached to the indoor unit body 2000.

The elastic member 1770 is installed in the elastic member receiving groove 1714 of the pulley receiving member 1710 so as to support both ends of the pulley rotary shaft 1760 provided on the pulley accommodating member 1710 by elastic force.

In the present embodiment, the elastic member 1770 is a compression spring but can be used as long as it has elasticity of a predetermined height.

The cover 1780 is tightly attached to the upper surface of the drum receiving member 1710 and fastened to the cover fixing portion 1715 with a fastening screw 1790 so as to restrict the upward movement of the drum pulley 1750.

It is preferable that the cover 1780 further include a positioning pin 1701 that is inserted into both ends of the donut-receiving member 1710 and determines its position.

Therefore, the positioning pin 1701 for positioning the donut-receiving member 1710 at both ends of the cover 1780 is inserted into the cover 1780, thereby facilitating the assembly of the cover 1780 on the donut-receiving member 1710.

The roller receiving member 1710 is provided with shaft receiving portions 1717 on both sides thereof to support the rotation shaft 1730 of the load sensing pulley protruding from the slot 1712 from below.

A position where the micro limit switch 1740 is operated by the shaft receiving portion 1717 protruding from both sides of the pulley accommodating member 1710 to support the load sensing pulley rotary shaft 1730 protruding from the slot 1712 from below Can be accurately set.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention if they are apparent to those skilled in the art.
