Problems solved by technology

[0002] When cooking in today's home kitchen, when the stove burns natural gas or gas, it will produce a certain amount of harmful exhaust gas, such as CO, NOx or leaked gas, etc. Although these exhaust gases are not easy to detect through people's sense of smell, but If the exhaust gas cannot be discharged outside in time, it will cause certain harm to people's health.

example 1

[0040] After the air quality sensor is initialized for 1 minute, if the actual value detected by it is 60, it means that the air quality is particularly poor. At this time, the fan is controlled to work for 3 minutes, and then the value of the reference value B is recorded as 40, and the air quality sensor continues Detect air quality, if the detected value at this time is 35, since 40-5=35, then update the reference value B to 35, since 35 is greater than 30, then reacquire the data detected by the air quality sensor, if the detected value is 20 ,35-5=30, update the reference value to 30 at this time, since 30=V2, the reference value is still 30, and then reacquire the data detected by the air quality sensor, if the detection value is 35, the controller starts the fan to work 3 minutes, and then reacquire the data detected by the air quality sensor.

example 2

[0041] Example 2: After the air quality sensor is initialized for 1 minute, if the actual value detected by it is 35, set the reference value B to 35, and then reacquire the data detected by the air quality sensor. If the detected value is 45, then The controller controls the fan to work for 3 minutes, and then reacquires the data detected by the air quality sensor.

[0042] The above two examples are just a specific description, the actual work is based on the actual detection value according to figure 1 implementation of the control process.

Abstract

Provided is a control method of an extractor hood with the air quality detection function. The extractor hood comprises a controller, an air quality sensor and a draught fan, and the air quality sensor is connected with the controller. The control method is characterized by comprising the steps of initialization of the air quality sensor and the like. The quality condition of air inside a kitchen is obtained through the air quality sensor installed on the extractor hood; when the quality of air inside the kitchen is poor, the extractor hood can be automatically controlled to work, environmental cleanliness of the kitchen is kept, and good health of people is facilitated.

Description

technical field [0001] The invention relates to a control method of a range hood with an air quality detection function, in particular to a control method of a range hood which can automatically control exhaust air according to the air quality of a kitchen. Background technique [0002] When cooking in today's home kitchen, when the stove burns natural gas or gas, it will produce a certain amount of harmful exhaust gas, such as CO, NOx or leaked gas, etc. Although these exhaust gases are not easy to detect through people's sense of smell, but If the exhaust gas cannot be discharged outdoors in time, it will cause certain harm to people's health. In order to overcome the above defects, the control method of range hood with air quality detection function is developed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control method for a range hood with an air quality detection function, which can automatically co...
