Referring to fig. 1, an embodiment of the present invention is a control system for a temperature-sensing variable frequency fan, the system includes a temperature sensor and a control unit, the temperature sensor is connected to the control unit, and the control unit is connected to a fan motor, in use of the fan, the temperature sensor may be installed inside an outer casing of the fan, and since the material of the outer casing of the fan does not usually block the temperature, the temperature value collected by the temperature sensor inside the outer casing is substantially close to the ambient temperature of the position where the fan is located. The control unit may be a commercially available single-chip module or a central processing unit, which is not described in detail here, and has a structure as follows:
the temperature sensor is used for collecting a current temperature value after the system is started, and transmitting the temperature value collected for the first time to the control unit as a first temperature value, wherein the first temperature value collected by the temperature sensor is an environment temperature value of the position of the fan. When the system starts each time, the control unit takes the temperature value firstly collected by the temperature sensor as the first temperature value and takes the temperature value as a reference to adjust the air output of the fan.
The temperature sensor is also used for continuously acquiring the current temperature value according to the time interval and continuously transmitting the current temperature value to the control unit. The aforementioned interval time can be set according to actual needs and different environments in which the fan is used, and generally the interval can be set to 10-30 min.
Above-mentioned the control unit is used for using first temperature value as the benchmark, when receiving the temperature value once more, compares with first temperature value, if be less than first temperature value, then controls fan motor and reduces fan speed, otherwise then controls fan motor and risees fan speed to by the control unit according to current ambient temperature, adjust fan speed, and then the air output size of control fan is favorable to promoting human body and feels the comfort level.
In addition, because the indoor temperature does not change much under the condition of no refrigeration equipment, the temperature value comparison change can be based on 1 ℃, namely, if the temperature value of the comparison value is 1 ℃ higher than the first temperature value, the control unit controls the fan motor to be increased by one gear. Otherwise, if the temperature value of the comparison value is 1 ℃ less than the first temperature value, the control unit controls the fan motor to reduce the first gear, and the rotating speed of the fan motor is controlled in a circulating mode.
Preferably, in order to facilitate the control unit to control the fan to have consistency in the ascending and descending of the rotating speed of the fan, a plurality of gears may be preset in the control unit, each gear corresponding to a different output power of the fan motor, so that the control unit controls the fan motor to reduce the rotating speed of the fan to one gear. The control unit controls the fan motor to increase the fan speed to one gear.
Referring to fig. 2, according to another embodiment of the present invention, in addition to the temperature sensor and the control module, when the system is used on a fan, in order to implement integral control, a switch reset key 1, a pitching head key 2, a horizontal head key 3, a pitching head motor, and a horizontal head motor may be added to the system, and the switch reset key, the pitching head key, and the horizontal head key are designed on a control panel 5 of a fan housing, as shown in fig. 3. The pitching and shaking motor and the horizontal shaking motor are in power connection with respective driving mechanisms, and then the switch reset key 1, the pitching and shaking key 2, the horizontal shaking key 3, the pitching and shaking motor and the horizontal shaking motor are all connected to the control unit, so that the switch reset key triggers the control unit to control the on-off of the fan power supply, and the pitching and shaking motor and the horizontal shaking motor are controlled to drive the driving mechanisms to reset the fan head to an initial state. The control unit is respectively triggered by the pitching oscillating key and the horizontal oscillating key to control the starting and stopping of the pitching oscillating motor and the horizontal oscillating motor. In addition, in order to facilitate the start and stop of the control system of the temperature-sensing variable frequency fan, a temperature-sensing variable frequency key 4 can be additionally arranged on the control panel, and the temperature-sensing variable frequency key triggers the control unit to start or close the control system of the temperature-sensing variable frequency fan with the functions.
Based on the above embodiment, through corresponding program settings, each key can trigger the control unit to execute a corresponding function, for example, when the horizontal oscillation key is pressed for a short time, power on-off control of the fan motor can be performed, and the fan can be turned off when the speed is adjusted for a long time, and after the fan is turned off, the pitching oscillation motor and the horizontal oscillation motor can also be controlled to drive the fan head to reset to an initial state. When the pitching oscillating key and the horizontal oscillating key are pressed for a short time, the pitching oscillating motor and the horizontal oscillating motor can be turned on or off. When the temperature-sensing frequency conversion key is pressed for a short time, the control system of the temperature-sensing frequency conversion fan is started or closed.
Referring to fig. 4, another embodiment of the present invention is a control method for a temperature-sensitive variable frequency fan, including the steps of:
and step S1, starting the system, collecting the current temperature value by the temperature sensor, and transmitting the temperature value collected for the first time to the control unit as the first temperature value. After the system is powered on, a temperature sensor in the fan acquires the temperature value of the position where the fan is located, and the first acquired temperature value is used as a reference, and the following steps are continued.
And step S2, the temperature sensor continuously collects the current temperature value according to the time interval and continuously transmits the current temperature value to the control unit. In this step, in addition to the first temperature value acquired for the first time, at least one temperature value is present as a comparison value. As mentioned above, during the execution of the method, the temperature sensor collects the current ambient temperature at certain time intervals, for example, once every 10-30min, and transmits the collected ambient temperature to the control unit, and the time intervals can be adjusted according to the actual environmental requirements, for example, in a place where the ambient temperature changes greatly, a shorter time interval can be set, and in a place where the ambient temperature changes little, a relatively longer time interval can be set.
Step S3, the control unit compares the first temperature value with the first temperature value when receiving the first temperature value again, and controls the fan motor to decrease the fan speed if the first temperature value is less than the first temperature value, otherwise controls the fan motor to increase the fan speed. The comparison may be performed in degrees celsius, i.e. if the temperature value of the comparison value is 1 ℃ greater than the first temperature value, the control unit controls the fan motor to shift up by one gear. Otherwise, if the temperature value of the comparison value is 1 ℃ less than the first temperature value, the control unit controls the fan motor to reduce by one gear, and the process is repeated.
Further, in order to facilitate the control unit to control the actual rotation speed of the fan, a plurality of gears may be built in the control unit in advance, and each gear corresponds to a different output power of the fan motor, in contrast to the above step S3, the control unit controls the fan motor to decrease the rotation speed of the fan by one gear. The control unit controls the fan motor to increase the fan speed to one gear.
In the embodiment, the method takes the ambient temperature of the position of the fan as a temporary reference value, and adjusts the rotating speed of the fan according to the temperature change after the fan is started by taking the temporary reference value as a reference, so that the air output of the fan is consistent with the curve change of the indoor temperature, the human body feeling is effectively improved, a preset threshold value and a wind speed mode are not needed, and the control mode is simple and effective.
