In the fast warm mode, the rotation speed of the fan 30 is high, and the air flow can be accelerated, so that the indoor temperature is rapidly raised.

In one embodiment, the heater includes a balance key electrically connected to the control chip to stop the fan 30 or rotate at a second rotation speed, wherein the second rotation speed is less than the first rotation speed. That is, the warmer has a balanced mode. When the indoor temperature tends to be stable, the rotating speed of the fan 30 is reduced, or the fan 30 is turned off, and the natural convection of the heating main body 10 is relied on at the moment, so that the energy consumption of the warmer can be reduced.

The specific type of the fast warm key is not limited, and may be, for example, a physical key, a touch key, or the like, which is not limited herein. Similarly, the specific type of the balance key is not limited, and for example, the balance key may be a physical key, or may be a touch key.

In some embodiments, the balance key and the fast warm key may be integrated into the same key. That is, the warmer is provided with one function key. The operation mode of the function key is not limited, for example, the function key is triggered for multiple times, and the warmer can cyclically select the balance mode and the quick warming mode. For another example, after the user triggers the function key, the heater enters the quick heating mode, and after the preset time, the quick heater automatically enters the balance mode, so that the energy consumption of the heater can be reduced. The predetermined time may be determined according to actual conditions, such as half an hour, one hour, and the like.

In other embodiments, the balance key and the quick warm key are independent. Specifically, after the user triggers the balance key, the warmer enters the balance mode. And after the user triggers the quick-heating key, the warmer enters a quick-heating mode.

The specific type of the heater is not limited, for example, in an embodiment, the heater is an electric oil heater, the heating body 10 includes a plurality of heating fins 11 connected in series, and the heating fins 11 enclose heat conducting oil therein. After the heat conducting oil is heated, the heat is transferred to the heating fins 11, and the heating fins 11 are heated to heat surrounding air.
