Among them, the technology of electric heating devices is also diverse, but usually they mainly use a number of heating tubes or heating wires for heating. However, the dehumidifier heaters currently on the market are all like an air heating device with application number CN201520023353.3, which has no internal guide structure, resulting in the air inlet entering the heater and encountering obstacles such as mica sheets and the bottom shell opposite the air inlet before changing the wind direction to discharge air. As a result, most of the flowing air is concentrated at the air outlet opposite the obstacle of the air inlet, making the air outlet density uneven, resulting in uneven air heating. The negative effects of the uneven heating of the air by the heating wire are as follows: 1. In areas with no wind or little wind, the heating wire will turn red with high temperature, affecting the life of the heating wire; 2. In areas with no wind or little wind, where the heating wire turns red with high temperature, the limiting mica sheet will be carbonized and decomposed at high temperature, affecting the life of the limiting mica sheet; 3. The uneven heating of the air leads to a decrease in the thermal efficiency of air heating, affecting the dehumidification effect, and making the dehumidification amount relatively insufficient.
