Fan simulating natural wind and natural wind simulating method

Abstract

The invention discloses a fan simulating natural wind. The fan comprises a fan body and a control part, wherein the fan body is provided with a head shaking motor, a fan blade rotating motor and a sprinkling can device; the control part comprises a user control panel, a controller, a temperature and humidity sensor and a pyroelectric infrared sensor; the temperature and humidity sensor, the pyroelectric infrared sensor and the sprinkling can device are in communication connection with the controller; the controller stores a plurality of comfortable natural wind speed samples collected in different regions and under different environment conditions; when the environment humidity measured by the temperature and humidity sensor is lower than a set value in the controller, the controller controls the sprinkling can device to spray mist for adjusting the environment humidity; and after the controller processes received temperature and humidity signals of the current temperature and humiditysensor, heat source position signals of the pyroelectric infrared sensor and heat source temperature signals, corresponding natural wind sample signals are obtained from a storage to control the headshaking motor to swing by a preset amplitude relative to a heat source, and the effects of simulating the natural wind and saving energy are achieved.

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
