Problems solved by technology

This is because in a low temperature environment, the lubricating oil in the fan will thicken or even solidify, resulting in poor lubricating effect of the lubricating oil and increased resistance for the fan to start.
In addition, after the fan is used for a period of time, the lubricating oil and grease will evaporate, making it more difficult to start
This has led to the fact that the newly bought heater is normal when it is purchased in the mall, and it cannot be started after a perio

Embodiment 1

[0046] In Embodiment 1, the device for controlling fan startup includes:

[0047] The voltage dividing module 5 is connected in series with the fan 1, and is used to divide the pressure of the fan 1 when it is not short-circuited;

[0048] A short-circuit module 6, connected in parallel with the voltage divider module 5, for short-circuiting the voltage divider module 5 during operation;

[0049] The control module 3 is connected with the short-circuit module 6, and is used to control the short-circuit module 6 not to work when the ambient temperature of the fan 1 is lower than the preset temperature, and to control the short-circuit module when the ambient temperature is higher than the preset temperature 6 work.

[0050] It should be noted that the voltage dividing module 5 includes but is not limited to a voltage dividing resistor, as long as it is an electronic component that has a certain resistance value and can divide a certain voltage from the fan 1 so that the fan 1 ...

Embodiment 2

[0071] The difference between the second embodiment and the first embodiment is that the first embodiment uses the thermistor 8 to change its own resistance according to the change of the ambient temperature, so as to control the connection and disconnection of the short-circuit module 6, which is not required in the first embodiment. The controller does not need to sense the specific temperature of the environment in the first embodiment. In the second embodiment, the temperature sensor 4 detects the ambient temperature information around the heating element 2 in real time, and sends the temperature information to the controller. There is a preset temperature in the controller. When the temperature detected by the temperature sensor 4 is less than When the preset temperature is reached, the controller controls the electronic switch to be turned off; when the temperature detected by the temperature sensor 4 is greater than or equal to the preset temperature, the controller cont...

Abstract

The invention relates to a device and method for controlling startup of a fan and an air heater using the device. The device for controlling startup of the fan comprises a voltage diversion module, ashort circuit module and a control module, wherein the voltage diversion module is connected with the fan in series and is used for voltage diversion of the fan, the short circuit module is connectedwith the voltage diversion module in parallel and is used for short circuits of the voltage diversion module in work, and the control module is connected with the short circuit module and is used forcontrolling the short circuit module not to work when the environment temperature of the fan is lower than a preset temperature and controlling the short circuit module to work when the environment temperature of the fan is higher than the preset temperature. According to the device and method for controlling startup of the fan and the air heater using the device, when the temperature is low, under-voltage startup of the fan is achieved; and after the fan is started, it can be ensured that the fan operates at a normal voltage. By adoption of the device and method for controlling startup of thefan and the air heater using the device, the problem that the fan cannot be started under a low temperature and the problem that the fan cannot operate normally after being started under the low temperature are solved.

Description

technical field [0001] The invention relates to the technical field of fan control, in particular to a device and method for controlling fan startup and a heater using the device. Background technique [0002] Existing air heaters all generate heat through a PTC (Positive Temperature Coefficient, positive temperature coefficient) heating element, and then the fan positioned behind the PTC heating element radiates heat to the PTC heating element. The hot air blown out by the radiator is used to heat the room. [0003] The fan on the heater is divided into AC and DC. The AC fan is directly powered by the mains, and the DC fan is generally powered by the mains after step-down and rectification. However, whether it is an AC fan or a DC fan, it is inevitable to increase the starting power in a low temperature environment. This is because in a low temperature environment, the lubricating oil in the fan will thicken, or even solidify, resulting in poor lubricating effect of the l...
