A fan for simulating natural wind and method for simulating natural wind

Abstract

The fan for simulating natural wind according to the present invention includes a fan body with a head-shaking motor, a fan blade rotation motor and a watering can device; and a control unit including a user control board, a controller, a temperature and humidity sensor and a pyroelectric infrared sensor, wherein, The temperature and humidity sensor, pyroelectric infrared sensor, and watering can device are respectively connected to the controller by communication. The controller stores a number of comfortable natural wind speed samples collected in different regions and under different environmental conditions. When the ambient humidity measured by the temperature and humidity sensor When it is lower than the set value in the controller, the controller controls the watering can device to spray to adjust the ambient humidity. The controller receives the current temperature and humidity signal from the temperature and humidity sensor, the heat source position signal from the pyroelectric infrared sensor and After the heat source temperature signal is processed, the corresponding natural wind sample signal is obtained from the memory to control the shaking head motor to swing to the heat source with a predetermined range, so as to achieve the effect of simulating natural wind and saving energy.

Description

technical field [0001] The invention belongs to the field of home appliances, and in particular relates to a fan for simulating natural wind and a method for simulating natural wind. Background technique [0002] With the improvement of people's requirements for comfort, more and more different types of electric fans that simulate natural wind have poured into the market. The most common one is to use temperature sensors to adjust the wind speed according to temperature changes to simulate natural wind. However, the simulated natural wind is affected by many factors, such as air temperature, relative humidity, turbulence intensity of the simulated wind, and action time, etc. It is not successful to adjust the wind speed and stop operation simply according to the change of a certain influencing factor. Simulate natural wind to meet human comfort. And studies have shown that natural winds in different environments, regions, and wind speeds have similar spectral characteristic...

AI Technical Summary

Problems solved by technology

[0003] For example, in the existing technical solutions, the user only controls the speed of the motor to drive the fan blades through changes in the ambient temperature or the temperature of the heat source of the human body, so as to control the magnitude of the wind force; the user controls the operation of the fan by setting the temperature limit at which the fan motor stops running. Stopping may not meet the human body's hair-drying needs

Moreover, the adjustment of the air supply angle of the fan is not convenient enough. When shaking the head: it is easy to cause waste of wind power; when it is fixed: it is easy to cause uncomfortable blowing due to concentrated wind force, so a reasonable swing movement is required
