Abstract

An indoor unit of an in-ceiling mount type air conditioner includes a box-shaped housing having a top plate portion, a side plate portion and an opening portion at the lower portion thereof, a face panel detachably mounted on the opening portion of the housing, an indoor heat exchanger through which the inside of the housing is compartmented into a primary side and a secondary side, and an air blower secured to the top plate portion of the housing that faces the primary side, has a primary side heat insulating material is provided to the top plate portion so as to face the primary side of the housing and a secondary side heat insulating material provided to the side plate portion so as to face the secondary side of the housing, wherein the primary side heat insulating material is provided with an opening portion through which the air blower is fixed to the top plate portion.

Description

technical field [0001] The present invention relates to an indoor unit of a ceiling-embedded air conditioner in which the inside of a housing is insulated. Background technique [0002] Conventionally, the indoor unit of the ceiling-embedded air conditioner has a box-shaped housing with an opening on the lower side, and the inside of the housing is divided into a primary side space and a secondary side space by an indoor heat exchanger. The primary side space is divided by the top plate of the housing and the indoor heat exchanger, and the air before air conditioning is drawn from the room into the primary side space. In addition, the secondary side space is partitioned by the side plate portion, the top plate portion of the housing, and the indoor heat exchanger, and air-conditioned air is sent from the primary side space to the secondary side space. On the side plate portion and the top plate portion of the secondary side space facing the casing, a secondary side heat ins...
