REAL-TIME COOKING FUME CONCENTRATION MONITORING SYSTEM AND RANGE HOOD APPLYING THE SAME

Document Type and Number:

WIPO Patent Application WO/2017/166890

Kind Code:

A1

Abstract:

A real-time cooking fume concentration monitoring system comprises an electrical box with a confined space inside. The electrical box is provided with a partition plate (5) for dividing the inner space of the electrical box into a first chamber (A) and a second chamber (B) which are not connected with each other. Inside the first chamber (A) there is provided with a signal transmitting unit (2) capable of emitting a pulsed optical signal. Inside the second chamber (B) there is provided with a signal receiving unit (3) capable of receiving the pulsed optical signal emitted from the signal transmitting unit (2). A portion of the electrical box, which is opposite to the signal transmitting unit (2) and the signal receiving unit (3), is a light transmissive region. The signal output terminal of the signal receiving unit (3) is connected with a data processing unit (7) capable of calculating a cooking fume concentration signal in real time from an optical signal intensity received by the signal receiving unit (3). The real-time cooking fume concentration monitoring system detects fume concentration using a non-contact manner, with low power consumption, and can help meet the requirements by whole machine standby energy efficiency; and the signal detection sensitivity is high. A range hood, comprising the real-time fume concentration monitoring system.
