Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flow chart illustrating a method for controlling an air heater according to an exemplary embodiment of the present disclosure. The air heater is internally provided with a heating unit, a fan and a temperature sensor. When the fan is in working state, the outside air can be kept to be gushed from the air inlet of the air heater. The heating unit may heat the intake air by heat radiation. The heated intake air is blown out from the air outlet of the air heater along with the air flow, thereby adjusting the temperature of the outside air. The method comprises the following steps:
and S11, detecting the air inlet temperature T of the air heater.
Step S12 is performed when it is detected that the intake air temperature of the air heater is higher than the first temperature threshold T1, i.e., T > T1.
And S12, controlling the heating unit of the air heater to stop heating, and keeping the fan of the air heater in a working state after controlling the heating unit to stop heating.
When it is detected that the intake air temperature of the air heater is higher than the first temperature threshold, i.e., T < ═ T1, step S13 is performed.
And S13, keeping the heating unit of the air heater in a working state, and keeping the fan of the air heater in a working state.
Through the technical scheme, the following technical effects can be at least achieved:
when the inlet air temperature of the air heater is detected to be higher than a first temperature threshold value, the heating unit of the air heater is controlled to stop heating, and after the heating unit stops heating, the fan of the air heater is kept in a working state, so that the inlet air of the air heater can be kept after the heating unit stops heating, the temperature sensor in the air heater can sense the real temperature of the outside air, and the heating unit is started in time when the temperature of the outside air is reduced.
Fig. 2 is another method for controlling an air heater, exemplarily shown in the present disclosure, the method including:
and S21, detecting the air inlet temperature T of the air heater.
Step S22 is performed when it is detected that the intake air temperature of the air heater is lower than the low temperature threshold T0, i.e., T < ═ T0.
And S22, keeping the heating unit in a high-power working gear.
The heating unit can be in working positions with different powers, for example, the power of a high-power working position is 3.5w, and the power of a low-power working position is 2.8 w. When the air temperature is lower than 10 ℃, the human body feels cold and uncomfortable, so the low temperature threshold T0 can be set to be 10 ℃. Like this, when detecting that the inlet air temperature is less than 10 ℃, this heating element is in high power operating position, can heat the admission more fast to make outside air rapid heating up.
As the heating unit continuously heats the air, the temperature of the outside air rises, and the temperature of the air inlet gradually rises, so that the power of the heating unit can be properly reduced. Further, the user generally sets the target temperature Tset. The air heating unit may be controlled to stop heating in case the intake air temperature is greater than the target temperature Tset for energy saving.
In the case where it is detected that the intake air temperature of the air heater is not lower than the temperature threshold T0 and is not higher than the target temperature Tset by a certain temperature, for example, T > T0 and T < ═ Tset +2 ℃, step S23 is performed. In the case where it is detected that the intake air temperature of the air heater is higher than the target temperature Tset by a certain temperature, for example, T > Tset +2 ℃, step S24 is executed.
And S23, switching the heating unit from a high-power working position to a low-power working position.
And S24, controlling the fan to continuously work within a first preset time period after the heating unit stops heating, and controlling the fan to be switched from a continuous working state to an intermittent working state when the first preset time period is over.
Illustratively, the fan is continuously operated within 3 minutes after the heating unit stops heating, and after the 3 minutes, the fan is controlled to be switched from the continuous operation state to the intermittent operation state in which the operation is suspended for 1 minute every 2 minutes.
Firstly, the heating unit continuously works for 3 minutes after stopping, so that the waste heat radiated by the heating unit can be fully utilized; then, the temperature sensor is switched to the intermittent working state, so that the temperature sensor can sense the temperature of the outside air instead of the temperature of the gas in the air heater after the heat radiation of the heating unit.
Further, when it is detected again that the intake air temperature of the air heater is lower than the target temperature Tset by a certain temperature, for example, T < ═ Tset-1 ℃, after the fan is controlled to stop heating in the heating unit, step S25 is executed.
And S25, controlling the heating unit to start heating, and controlling the fan to keep a continuous working state.
That is, when the inlet air temperature is detected to be lower than Tset-1 ℃, the heating unit and the fan are controlled to enter a normal working state, so that the air heater can play a heating function.
