  Conventionally, as an example of this type of air conditioner panel structure, a panel structure of a mist apparatus that is installed on a ceiling surface and performs air conditioning is known (see, for example, Patent Document 1).

  Hereinafter, the mist device will be described with reference to FIG. As shown in the figure, a grill plate 104 is provided to cover an apparatus main body 103 provided with a circulation fan 101 and a movable louver 102, and the apparatus main body 103 is placed indoors through an intake port 105 provided with a number of crosspieces 105a in a main body casing 103a. A circulation ventilation path 107 for sucking air and blowing out air through the outlet 106, a circulation fan 101 for ventilating the circulation ventilation path 107, and a heat exchanger for heating the air flowing through the circulation ventilation path 107 108, a movable louver 102 that can change the blowing direction of the air blown out through the blowout port 106, and an air conditioning means such as a ventilation fan 110 that sucks indoor air and exhausts it outside through the exhaust duct 109. The grill plate 104 is mounted via the ceiling 111 by a plurality of panel fixing means 112 such as screws. It was constructed which is fixed to the body 103.

  In addition, there are various types of panel structures for this type of air conditioner. However, when resin panels are used, cracks may occur at the location where the panel is fixed due to a number of factors such as aging, solvent-related factors, and stress. There is a problem that there is a possibility of falling, and various means for suppressing panel drop are taken. As an example, a ventilation fan that is installed on a wall surface and performs air conditioning is known (see, for example, Patent Document 2).

Hereinafter, the ventilation fan will be described with reference to FIG. As shown in the figure, a sliding plate 114 is slidably provided on the main body frame 113. When the sliding plate 114 slides, the panel 115 moves integrally and the suction port 116 is opened and closed. On the other hand, since the panel 115 is connected to the sliding plate 114 as the screw 119 is tightened to the boss 118 through the screw fixing portion 117 of the sliding plate 114, the panel 115 is hooked when the boss 118 is damaged. Since the portion 120 is supported downward by the screw fixing portion 117 of the sliding plate 114 and engages with the protrusion 121 of the sliding plate 114, the panel 115 is prevented from falling off.
