Description
Technical Field
The present invention relates to a sensor unit and an indoor unit of a ceiling-embedded air conditioner provided with the sensor unit, and more particularly to a structure of the sensor unit.
Background
Some conventional indoor units of ceiling-embedded air conditioners include an indoor unit including a sensor unit (see, for example, patent document 1). The indoor unit of the air conditioner of patent document 1 includes a casing and an outlet panel. The discharge port panel is mounted to the front surface of the housing.
The discharge port panel includes a discharge port portion and a sensor mounting portion located on the right side of the discharge port portion. The outlet portion is provided with an opening portion constituting an outlet for discharging air. The opening is provided with a plurality of horizontal blades that can rotate about an axis that runs along the longitudinal direction of the indoor unit of the air conditioner. In addition, a plurality of vertical blades that can rotate about an axis extending in the height direction of the indoor unit of the air conditioner are provided behind the plurality of horizontal blades of the outlet panel.
The sensor unit is detachably attached to the sensor attachment portion, and detects a floor temperature and a person in a room. Then, based on the detection result of the sensor unit, the horizontal blade and the vertical blade are driven and controlled, thereby controlling the temperature of the air discharged from the discharge port panel, and making the air-conditioning target area a comfortable environment.
The sensor mounting portion is mounted with a sensor mounting plate so as to protrude forward from the discharge surface of the discharge port panel. The plane on which the sensor mounting plate is located forms an acute angle θ with respect to the thickness direction of the discharge port panel, i.e., the front-rear direction of the indoor unit of the air conditioner. That is, the sensor unit is disposed so as to protrude from the exterior decorative surface, is disposed at an acute angle to the floor surface, and is disposed so as to face downward with respect to the front surface of the discharge port panel.
