Description

Technical Field

[0001] The present invention relates to the technical field of air fans, and more specifically, to a control method for a portable cooling and humidifying air fan. Background Art

[0002] In the field of air fans, it is of great significance to study the control method of portable cooling and humidifying air fans. With global climate change and the increase of extreme weather events, people's demand for indoor environmental comfort is getting higher and higher. Traditional air fans can only provide wind power and cannot meet people's needs for temperature and humidity. Therefore, the development of an air fan that can both cool down and humidify will greatly improve the indoor air quality and improve people's quality of life. In addition, by accurately controlling the working state of this air fan, energy conservation and emission reduction can be achieved, energy consumption can be reduced, and it is beneficial to environmental protection.

[0003] Prior to the present invention, the control method of the existing portable cooling and humidifying air fan mainly adopts the method of combining the regeneration temperature adjustment of the absorbent material and the detection of the humidity sensor. The technical difficulty lies in how to extend the service life of the absorbent material and reduce power consumption while ensuring the humidification efficiency. The key points include accurately controlling the power of the heater, adjusting the speed of the humidifying fan and the adsorption rotor, and designing a reasonable humidifier structure to achieve efficient humidity exchange. Specifically, in the prior art, absorbent materials such as zeolite or silica gel desiccant are usually used to control the indoor humidity by adjusting their regeneration temperature. Although this control method can meet the humidification requirements, long-term operation at a high regeneration temperature will shorten the service life of the absorbent material, and the evaporation of water during high-temperature heating will consume more energy. In addition, the portable cooling and humidifying air fan in the prior art also involves how to effectively integrate wind power and humidity output, and how to design a control method that is easy for users to operate. For example, some prior arts realize the humidification function when the fan is discharged by setting a water storage tank and a vaporization structure, and set an adjustable baffle at the fan outlet to optimize the air volume and humidity output. However, these designs are often more complicated and it is difficult to take into account portability, energy consumption and user experience at the same time. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0081] In the field of air fans, it is of great significance to study the control method of portable cooling and humidifying air fans. With global climate change and the increase of extreme weather events, people's demand for indoor environmental comfort is getting higher and higher. Traditional air fans can only provide wind power and cannot meet people's needs for temperature and humidity.

Then, small water supply pipes and air supply pipes are integrated inside the fan frame, which are led out from their respective water storage areas and air storage areas and extend to the vicinity of the fan outlet. Water pipelines should be equipped with micro pumps to control the speed and direction of water flow to ensure that the water can be evenly distributed into the air. Gas pipelines should be designed with regulating valves to control the air flow to ensure that the airflow and water vapor are fully mixed and evenly output.

[0121] In an embodiment of the present invention, the sensor monitors the current humidity and transmits the data to the control unit. A fiberglass tube is provided from the water storage area to the top of the fan for gas transmission. An atomizer is provided at the outlet of the water storage area. The output flow of the atomizer is controlled by the control unit, which calculates the deviation according to the target humidity and determines the output flow of the atomizer using a PID algorithm according to the deviation. For example, when the actual humidity is lower than the target humidity, the control unit will increase the output flow of the atomizer; otherwise, the output flow will be reduced. This ensures that the indoor humidity remains within the set range.

[0122] Figure 5 The present invention is a flowchart of setting a multifunctional air outlet and automatically adjusting in a control method of a portable cooling and humidifying air fan according to an embodiment of the present invention.

[0126] S503, after the gas from the air outlet is discharged, it is carried to the blades by the wind of the fan and blown out.

[0127] In an embodiment of the present invention, an air outlet is arranged behind the fan blades, including a water vapor outlet and a liquid nitrogen outlet. The outside of the liquid nitrogen outlet is a passage between the water vapor outlet and the atomizer, and the liquid nitrogen is taken out together by the gas from the water vapor outlet after being discharged. After the gas from the air outlet is discharged, it is brought to the blades by the wind of the fan and blown out. For example, when humidification is required, the water vapor outlet is opened; when cooling is required, the liquid nitrogen outlet is opened. In this way, humidification and cooling functions can be achieved at the same time.

[0128] Figure 6 The present invention is a flowchart of a control method for a portable cooling and humidifying air fan in which a weighing device is arranged in a supporting frame and the real-time control temperature is adjusted through a remote controller according to the weighing of the weighing device.

[0132] S603, calculating and updating the control temperature using a fourth calculation formula according to the real-time increase ratio of the control temperature;

[0133] The third calculation formula is:

[0134] stbl=(zl-ysb)÷K

[0135] Wherein, stbl is the real-time control temperature increase ratio, zl is the weight of the electronic weighing device, ysb is the preset comparison value, and K is the temperature conversion coefficient;

[0136] The fourth calculation formula is:

[0137] temp2=(1+stbl)×temp

[0138] Among them, temp2 is the updated control temperature, stbl is the real-time increase ratio of the control temperature, and temp is the control temperature.

[0139] In an embodiment of the present invention, an electronic weighing device is arranged in the water support frame, and the real-time collected weight is converted into a voltage signal. When the voltage value exceeds the preset comparison value, the third calculation formula is used to calculate the real-time control temperature increase ratio; and the fourth calculation formula is used to calculate the updated control temperature according to the real-time control temperature increase ratio. For example, when the weight of the electronic weighing device is 500 grams and the preset comparison value is 400 grams, the real-time control temperature increase ratio is calculated to be 0.25 by the third calculation formula; and then the updated control temperature is calculated to be 20 degrees Celsius according to the fourth calculation formula (assuming that the original control temperature is 16 degrees Celsius). This ensures that a constant temperature can be maintained under different loads.

[0140] Figure 7 The present invention is a flow chart of a portable cooling and humidifying air fan control method according to an embodiment of the present invention, in which the liquid nitrogen output is automatically turned off when the air fan detects that no one is indoors or a window or door is open.

[0144] S703: If a door or window opening signal is obtained, the liquid nitrogen output is automatically turned off; otherwise, no processing is performed.

[0145] In an embodiment of the present invention, an unmanned monitoring button is provided inside the air fan, and the unmanned monitoring is to sense moving objects through infrared. If there is no moving object, the liquid nitrogen output is automatically turned off. For example, when the user leaves the room, the infrared sensor detects that no one is in the room, and the system automatically turns off the liquid nitrogen output to save energy. Otherwise, no processing is performed. If a door or window opening signal is obtained, the liquid nitrogen output is automatically turned off. For example, when the user opens the window for ventilation, the system receives a signal that the window is opened and automatically turns off the liquid nitrogen output to avoid wasting resources. Otherwise, no processing is performed. This ensures that the liquid nitrogen output is stopped in time when refrigeration is not required to save energy and increase the service life of the equipment.
