Indoor unit for air-conditioning apparatus

Abstract

The indoor unit for an air-conditioning apparatus includes: a fan; a heat exchanger located on a front side of the indoor unit with respect to the fan and on an upstream side with respect to the fan; an electrical component unit arranged in front of the heat exchanger in a horizontally long posture; a front designed panel located on a foremost side of the indoor unit in an openable and closeable manner; and an electrical component cover removably mounted to members forming a casing of the indoor unit, the electrical component cover including: a lower cover plate for covering a lower side of the electrical component unit; and a front cover plate for covering a front side of the electrical component unit. The front cover plate is exposed when the front designed panel is opened.

1 . An indoor unit for an air-conditioning apparatus, comprising:
 a fan to generate an air flow flowing from an air inlet formed at a top of the indoor unit to an air outlet formed in a lower portion of the indoor unit;   a heat exchanger located on a front side of the indoor unit with respect to the fan and on an upstream side with respect to the fan;   an electrical component unit arranged in front of the heat exchanger in a horizontally long posture;   a front designed panel located on a foremost side of the indoor unit in an openable and closeable manner; and   an electrical component cover removably mounted to members forming a casing of the indoor unit, the electrical component cover including
 a lower cover plate for covering a lower side of the electrical component unit, and 
 a front cover plate for covering a front side of the electrical component unit, 
   the front cover plate being exposed when the front designed panel is opened.   
     
     
         2 . The indoor unit for an air-conditioning apparatus of  claim 1 , wherein the lower cover plate is exposed in a front lower portion of the indoor unit even under a state in which the front designed panel is closed. 
     
     
         3 . The indoor unit for an air-conditioning apparatus of  claim 1 ,
 wherein the lower cover plate and the front cover plate of the electrical component cover are connected to each other through intermediation of a hinge structure, and   wherein the front cover plate is turnable downward to a front with respect to the lower cover plate under a state in which the front designed panel is opened.   
     
     
         4 . The indoor unit for an air-conditioning apparatus of  claim 1 , wherein the front cover plate is fastened with screws to the members forming the casing of the indoor unit so that the front cover plate is prevented from being turned with respect to the lower cover plate unless the screws fastening the front cover plate are unscrewed, and that the lower cover plate is prevented from being removed from the members forming the casing of the indoor unit unless the front cover plate is turned. 
     
     
         5 . The indoor unit for an air-conditioning apparatus of  claim 1 , wherein the members forming the casing of the indoor unit includes a right lateral panel and a left lateral panel for closing lateral surfaces of the indoor unit. 
     
     
         6 . The indoor unit for an air-conditioning apparatus of  claim 1 , wherein the lower cover plate and the front cover plate of the electrical component cover are different from each other in material. 
     
     
         7 . The indoor unit for an air-conditioning apparatus of  claim 1 , wherein the lower cover plate and the front cover plate of the electrical component cover are different from each other in plate thickness.
