Outdoor unit for air-conditioning apparatus

Abstract

The outdoor unit for an air-conditioning apparatus includes: a heat exchanger covering the opening of the rear surface of the housing from an inside of the housing; a fan motor support member having a part of the fan motor support member above the air-sending device being locked onto an upper end side of the heat exchanger and a part of the fan motor support member below the air-sending device being fixed onto a bottom panel of the housing; an inverted U-shaped locking plate formed on an upper side of the fan motor support member, the inverted U-shaped locking plate having a downward groove; and a size adjustment section to be fitted into the downward groove of the inverted U-shaped locking plate in accordance with a height and a thickness of the heat exchanger so that the heat exchanger is fitted into the downward groove of the inverted U-shaped locking plate through intermediation of the size adjustment section.

1 . An outdoor unit for an air-conditioning apparatus, comprising:
 a housing having an opening formed in a rear surface thereof and an air outlet formed in a front surface thereof;   a heat exchanger covering the opening of the rear surface of the housing from an inside of the housing;   a fan motor support member having an air-sending device fixed to a center portion thereof, a part of the fan motor support member above the air-sending device being locked onto an upper end side of the heat exchanger and a part of the fan motor support member below the air-sending device being fixed onto a bottom panel of the housing;   a locking section formed on an upper side of the fan motor support member, the locking section having a downward groove; and   a size adjustment section to be fitted into the downward groove of the locking section in accordance with a height and a thickness of the heat exchanger so that the heat exchanger is fitted into the downward groove of the locking section through intermediation of the size adjustment section.   
     
     
         2 . The outdoor unit for an air-conditioning apparatus of  claim 1 , wherein the size adjustment section has a downward groove, in which an upper end portion of the heat exchanger is to be fitted. 
     
     
         3 . The outdoor unit for an air-conditioning apparatus of  claim 1 , further comprising:
 a stepped portion having a flat surface, which is formed on one side surface forming the downward groove of the locking section, the stepped portion being formed by cutting and raising a part of the one side surface; and   a hook portion formed on a surface of the size adjustment section on the stepped portion side, the hook portion being configured to be locked onto the stepped portion when the size adjustment section is fitted into the downward groove of the locking section.   
     
     
         4 . The outdoor unit for an air-conditioning apparatus of  claim 3 , further comprising a U-shaped regulation piece formed on a surface of the size adjustment section on an opposite side to the surface on the stepped portion side, the U-shaped regulation piece being configured to regulate lateral movement of the size adjustment section when the size adjustment section is fitted into the downward groove of the locking section. 
     
     
         5 . The outdoor unit for an air-conditioning apparatus of  claim 2 , further comprising a cushioning member fitted into the downward groove of the size adjustment section so as to absorb vibrations.
