Description

Indoor unit of air conditioner

This disclosure relates to an indoor unit of an air conditioner having a communication adapter.

An indoor unit having a communication adapter for wireless communication of an air conditioner is known. In the indoor unit of the conventional air conditioner, when operating the communication panel, the design panel in front of the communication panel is fully opened (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2016-38147

In the indoor unit of the conventional air conditioner, when operating the communication panel, there is a problem that the communication panel cannot be operated unless the design panel in front of the communication panel is fully opened. Further, there is a problem that the design of the air conditioner when operating the communication adapter cannot be maintained.

The present disclosure has been made in view of the above circumstances, and the interior of the air conditioner can suppress the deterioration of the design of the air conditioner even when the design panel is opened when operating the communication adapter. The purpose is to provide an opportunity.
Another object of the present disclosure is to provide an indoor unit of an air conditioner that can operate a communication adapter without fully opening the design panel and does not affect the design when the design panel is not in the open state.
