Method, device and equipment for detecting and controlling wind pressure of range hood and storage medium

Abstract

The invention discloses a method, device and equipment for detecting and controlling wind pressure of a range hood and a storage medium. The method for detecting and controlling the wind pressure of the range hood comprises the following steps that a first wind pressure value sensed by a first wind pressure detection module arranged at an air inlet of the range hood and a second wind pressure value sensed by a second wind pressure detection module arranged at an air outlet of the range hood are acquired when a motor is started; a current wind pressure reference value is calculated according tothe first wind pressure value and the second wind pressure value; a real-time first wind pressure value sensed by the first wind pressure detection module and a real-time second wind pressure value sensed by the second wind pressure detection module are acquired; according to the real-time first air pressure value, the real-time second air pressure value and the current air pressure reference value, the air volume change trend of the range hood is determined; according to the air volume change trend of the range hood, the air volume of the range hood is controlled; by updating the wind pressure reference value at each motor startup, the running status of a whole flue system and a wind cabinet system of the current range hood is reflected, the influence of system errors is eliminated, misjudgment is avoided, and the accuracy of wind pressure detection is improved.

Description

technical field [0001] The invention relates to the technical field of household appliance control, in particular to a method, device, equipment and storage medium for wind pressure detection and control of a range hood. Background technique [0002] Range hoods have maintained rapid development in recent years. Low noise and large air volume have become an important indicator of consumer satisfaction. Among them, the air volume reflects the smoke exhaust capability of the range hood, which is subject to the influence of the air duct system of the range hood itself and the public flue. Once the range hood has too much oil fume or the public flue is blocked, it will affect the exhaust air volume of the range hood, affect the exhaust effect of the range hood, and even affect the normal use of the range hood. [0003] At present, the existing range hoods can judge the blockage of the public flue or its own air duct system by detecting the current of the motor to control the i...

Once the range hood has too much oil fume or the public flue is blocked, it will affect the exhaust air volume of the range hood, affect the effect of the range hood, and even affect the normal use of the range hood

[0003] At present, the existing range hoods can judge the blockage of the public flue or its own air duct system by detecting the current of the motor to control the increase of the gear of the range hood; or by detecting the pressure change of the air outlet to judge the public flue. The blockage of the flue or its own air duct system is used to control the increase of the range of the hood; but on the one hand, the change value of the current will be affected by the deviation of the current detection device, the motor itself, the temperature, etc., and the detected current value or wind The pressure value is compared with a fixed set value to adjust the air volume gear. Too single judgment method cannot continuously reflect the current air volume in real time, and misjudgment is prone to occur.
