Range hood and wind speed and wind pressure sensor for range hood

Abstract

The invention discloses a wind speed and wind pressure sensor for a range hood. The wind speed and wind pressure sensor comprises a sampling part, wherein the sampling part comprises a pressure tapping pipe, a first pressure guide pipe, a second pressure guide pipe and a pressure sensor part; the first pressure guide pipe and the second pressure guide pipe are arranged at the end part of the pressure tapping pipe, and are connected to the pressure sensor part through conduits respectively; a partition plate is arranged in the pressure tapping pipe, and divides the pressure tapping pipe into a first pressure tapping cavity and a second pressure tapping cavity; the first pressure tapping cavity faces an air flow, while the second pressure tapping cavity is far from the air flow; the first pressure guide pipe is communicated with the first pressure tapping cavity; the second pressure guide pipe is communicated with the second pressure tapping cavity; high pressure tapping holes (14) communicated with the first pressure tapping cavity and low pressure tapping holes (15) communicated with the second pressure tapping cavity are formed in the pressure tapping pipe (1); the high pressure tapping holes (14) are positioned in the bottom of the pressure tapping pipe (1), and are inverted-V-shaped; the low pressure tapping holes (15) are positioned in the side wall of the pressure tapping pipe (1); and the low pressure tapping holes (15) and the high pressure tapping holes (14) are distributed in a staggered manner.

Description

Technical field [0001] The invention relates to a sensor, in particular to a wind speed and wind pressure sensor for a range hood, a range hood applying the wind speed and wind pressure sensor, and a method for adaptively adjusting and controlling the fan speed of the range hood. Background technique [0002] When the range hood is in use, when the amount of indoor oil smoke increases or the wind pressure of the public flue increases, it is necessary to adjust the motor speed to increase the exhaust air volume and improve the smoke exhaust effect. Traditional range hoods often require users to follow Subjectively feel the manual adjustment, which not only takes up busy hands, but also easily contaminates the fingers; automatic adjustment of the wind speed according to the environment can greatly enhance the intelligence of the cooker hood, which is one of the typical features of future kitchen appliances; automatically when the concentration of fumes is low Reducing the wind spee...

Problems solved by technology

However, the existing Verabar tubes used in air conditioning and HVAC systems, as commonly used flowmeters, are not suitable for the working environment of range hoods. , the condensed oil will often block the pressure tap hole, making the pressure tap not work properly, so further research is needed to obtain a wind speed and pressure sensor suitable for the working environment of the range hood
