PARTICLE SENSING DEVICE AND AIR CONDITIONER INCLUDING THE SAME

摘要

A particle sensing device and an air conditioner including a sensor has a sensing path through which air passes, a flow path housing which accommodates the sensor and guides air, and a flow path switching device to all air suctioned from the outside is guided to the sensing path, or some of the air suctioned from the outside and moving flows back in an obliquely upward direction and flows into the sensing path.

主权项

1. A particle sensing device comprising:
a sensor including a sensing path through which air passes; and a flow path housing which accommodates the sensor and guides air suctioned into the flow path housing from an outside, wherein in a first operational state of the particle sensing device, all of the air suctioned from the outside is guided to the sensing path, and in a second operational state of the particle sensing device, only a portion of the air suctioned from the outside flows into the sensing path, after changing flow direction inside the flow path housing to flow in an obliquely upward direction to reach the sensing path.
