Indoor unit and refrigeration cycle apparatus

Abstract

An indoor unit includes a case having an opening part on a lower surface thereof when the indoor unit is installed, and a decorative panel having a substantially rectangular air inlet being open to the opening part of the case and being attached to the lower surface of the case. The decorative panel has temporary hanging levers attached to opposed positions shifted to be parallel from midpoints on any opposed two of four sides on edges of the air inlet toward any opposed vertexes. The case has temporary hanging hooks corresponding to the temporary hanging levers on edges of the opening part.

1 . An indoor unit comprising:
 a case having an opening part on a lower surface thereof when the indoor unit is installed; and   a decorative panel having a rectangular air inlet being open to the opening part of the case, the decorative panel being attached to the lower surface of the case,   the decorative panel having temporary hanging levers attached to opposed positions shifted from midpoints on any opposed two of four sides on edges of the air inlet parallelly toward any opposed vertexes,   the case having temporary hanging hooks corresponding to the temporary hanging levers on edges of the opening part.   
     
     
         2 . The indoor unit of  claim 1 ,
 wherein the temporary hanging levers each have   a hook portion hooked on one of the temporary hanging hooks, and   an operating portion on which a finger can be placed to turn the hook portion.   
     
     
         3 . The indoor unit of  claim 2 , further comprising protruding portions for catching the turned temporary hanging levers, on the edges of the air inlet. 
     
     
         4 . The indoor unit of  claim 1 , wherein the temporary hanging levers are attached to opposed positions shifted toward opposed vertexes close to a position of the decorative panel to which an electric component box is attached. 
     
     
         5 . The indoor unit of  claim 1 , wherein, after the temporary hanging levers are hooked on the temporary hanging hooks, the case and the decorative panel are fixed with screws. 
     
     
         6 . A refrigeration cycle apparatus comprising: the indoor unit of  claim 1 ; and an outdoor unit,
 the refrigeration cycle apparatus having a refrigerant circuit connecting, by pipes, a compressor compressing and discharging refrigerant, a condenser condensing the refrigerant by heat exchange, an expansion device decompressing the condensed refrigerant, and an evaporator exchanging heat between the decompressed refrigerant and air.
