Description

  The present invention relates to a sensor unit having a non-contact type sensor that detects the temperature of an object in a non-contact manner, and an indoor unit of an air conditioner including the sensor unit, and particularly relates to the communication line of the sensor unit.

In a sensor unit having a non-contact type sensor that detects the temperature of an object in a non-contact manner, for example, there is one provided in an indoor unit of an air conditioner (for example, see Patent Document 1).
In the indoor unit of the air conditioner described in Patent Document 1, the non-contact sensor is rotated in the horizontal direction during operation, and the temperature of the human body in the air-conditioning target area, the temperature of the wall, the temperature of the floor, the position of the furniture, Activity, ceiling temperature, solar radiation, floor plan, etc. are scanned over a wide range. By doing so, it is possible to perform an operation without unnecessary air conditioning, that is, an operation with reduced power consumption. Note that main types of non-contact sensors include pyroelectric type, thermal electromotive force type thermal infrared detection sensors, and visible light cameras.

  Moreover, the indoor unit of the air conditioner described in Patent Document 1 has a non-contact type sensor housed in the housing unit of the indoor unit when stopped, so that the appearance influence can be suppressed. On the other hand, during operation, the non-contact sensor gradually starts to protrude from the indoor unit while rotating along the spiral guide, and the non-contact sensor stops once when it rotates to the end point of the guide. At this time, the non-contact type sensor is in a state of projecting to the maximum from the storage portion. Next, it rotates in the reverse direction to a certain angle, and when it rotates to the specified angle, it rotates in the reverse direction again. By repeating this operation, the object is scanned and detected over a wide range.
