Embodiment Construction

[0035] Next, an embodiment of the present invention will be described with reference to the drawings.

[0036] figure 1 is an example of a common ceiling-buried air conditioner, the figure 1 Among them, reference numeral 10 is an air conditioner. This air conditioner 50 is a unit 2 formed of a sheet metal that is installed in the ceiling 1, has a suction port 3 in the middle, and has an air outlet 4 on the four sides of the outer periphery, and is installed on the ceiling surface 6 to close the ceiling hole 5. The decorative panel 7 and the suction grille 9 with the suction port 8 in the middle constitute.

[0037] 10 is a fan made of a turbo blower 11 and a fan motor 13 installed on the top plate 12, 14 is an exhaust port that guides the indoor air from the air inlet 8 to the turbo blower 11, and 15 has an inner rising edge 15a and an outer side. The rising edge 15b is made of foamed styrene and has an angled ring-shaped water receiving tray. 16 is a plate-fin heat exchang...

Abstract

An in-ceiling mount type air conditioner including an operation switch for switching a power supply status of a power source to an elevating motor for elevating an air suction grille, upper-limit position detectors for detecting the upper-limit positions of the air suction grille, a timer for counting a predetermined time from the actuation of the upper-limit position detector, and a controller for stopping the elevating motor when the timer counts the predetermined time after the air suction grille reaches the upper-limit position and keeping the air suction grille to stop when the forced stop of the air suction grille is detected by the forced stop detector.

Description

technical field [0001] The invention relates to the installation structure of the suction grille of the ceiling-buried air conditioner with a unit body arranged in the ceiling, and the lifting control system of the suction grille. Background technique [0002] Generally, there is known a ceiling-embedded air conditioner in which a suction grill is provided on a decorative ceiling and a filter is provided on the grill (JP-A-2-233920). Because this type of air conditioner buried in the ceiling removes the air intake grille from the decorative panel and then removes the filter, compared with the previous air conditioner, it is easier to assemble and disassemble the filter or replace it with a new one. The maintenance of the net, etc. is relatively easy. [0003] However, in the air conditioner buried in the ceiling, it is natural to install the decorative board or the suction grille in the ceiling. Therefore, since the removal of the above-mentioned suction grille is carried o...
