Field of the Invention The present invention relates to an in-ceiling type air conditioner which cools or heats a room and buries an indoor unit body under the ceiling, or a ceiling-hanging type air conditioner in which the unit is hung from the ceiling. In particular, the present invention is suitable for cleaning, checking, or replacing a filter or a suction grill through which cold or hot air blown into a room passes.

Description of the Related Art In a ceiling-embedded type air conditioner in which a decorative panel is attached to a lower portion of a unit body, a rotary drum is provided, and the other end of a wire having one end wound on the rotary drum is sucked through a pulley to a grill. It is known that the suction grille is supported so as to be able to move up and down freely, and the suction grille and a filter supported by the suction grille are moved up and down by driving of a motor.

グリルを床面に対して水平を保つことが困難となる。In the above prior art, since one end of the wire is fixed, if the speed of the lifting operation is increased, the influence of winding unevenness of the wire on the motor side becomes smaller toward the fixed side. . Therefore, the wire winding speed is different between the motor side and the fixed side of the wire, and it is difficult to keep the suction grill horizontal with respect to the floor surface.

However, since the other end of the motor or the wire is fixed to a portion above the pulley of the unit body, a structure considering so-called recyclability is considered. However, further improvement is desired in order to smoothly lower the suction grille. Further, when a non-azeotropic refrigerant mixture, particularly R407C refrigerant, is used, the pressure under the same temperature condition becomes higher, and when the operation under the same condition as the conventional one is performed, the operation is performed at a higher pressure than the conventional one. Therefore, there is a problem that the operating pressure further increases due to the clogging of the suction grille or the filter, and the cooling / heating capacity is reduced, the reliability, and the life of the compressor is reduced.

になり、昇降に要する動力が低減される。The motors 21 and 24 are driven and controlled by a control unit (not shown), whereby the wire 13 is unwound from the rotating drums 12 and 25 or wound up and the suction grill 10 is raised and lowered. Since both ends of the wire 13 are wound around the rotating drums 12 and 25 via the guide rollers 20 provided on the suction grill 10, the suction grill 10 is wound symmetrically, so that it can be raised and lowered horizontally. Done. Therefore, it is easy to increase the speed of the lifting operation, and if the driving voltage is changed, for example, by finely adjusting the winding speed of the wire 13 by the motors 21 and 24, the suction grill 10 can be further improved.
Is good for leveling. Since the guide roller 20 is rotatably supported, the lift ratio is the same as the condition of the moving pulley, and the power required for lifting and lowering is reduced.

できる。When the suction grill 10 has descended to a predetermined position, the operation of the motors 21 and 24 is stopped by operating a remote controller (not shown) or the like. At this time, when there are a plurality of indoor units in the same room such as a building, it is desirable that one remote control lowers the suction grills 10 of the plurality of indoor units almost simultaneously. After the suction grill 10 is lowered, the filter 11 can be removed for cleaning or washing. When the refrigerant flowing through the heat exchanger 3 is a non-azeotropic mixed refrigerant, in particular, R407C refrigerant, the speed of the ascending and descending operation is fast and smooth, so that the suction grill or the filter can be frequently cleaned. Cooling and heating performance can be improved.

The wire 13 is wound on both 2 and 25 and the suction grill 10 is raised. Since a detector such as a micro switch 23 is attached to the decorative panel 7, the drive of the motor 21 can be automatically stopped when the suction grill 10 is stored in the suction port 8 of the decorative panel 7.

きる。Further, if the two rotating drums 12 and 25 and the motors 21 and 24 for driving them are provided on the decorative panel 7, one wire 13 is guided at four corners of the suction grill 10 and both ends are rotated. Since it is wrapped around 12, 25, the suction grille 10 can be moved up and down to maintain a horizontal position even when the elevating speed is increased, and can be moved up and down smoothly, and the main part of the elevating mechanism is located in the decorative panel 7. Maintenance and replacement, such as a failure of the lifting device, can be facilitated.
