The present embodiment provides a fan heater, as shown in fig. 1 to 7, including: wind-guiding structure 1, fan subassembly 2 and the piece 3 that generates heat, wind-guiding structure 1 includes convergent portion 4, and fan subassembly 2 sets up the big end department at convergent portion 4, and the piece 3 that generates heat sets up the one side at fan subassembly 2.

When the fan heater of this embodiment is in operation, as shown in fig. 5, the direction indicated by the arrow in fig. 5 is the direction of air flowing through the fan heater of this embodiment, the fan assembly 2 sucks air into the tapered portion 4, the air flows out from the small end of the tapered portion 4 after passing through the heat generating member 3, and the air carries away heat on the heat generating member 3 when passing through the heat generating member 3. The fan assembly 2 plays a role in accelerating air while sucking the air, and improves the air flow rate. When air flow passes through convergent portion 4, along with the cross-section of convergent portion 4 reduces gradually, the velocity of flow of air in convergent portion 4 increases, promptly on fan subassembly 2 basis to the air acceleration, has further increased the velocity of flow of air, has improved the air supply distance, can be faster with the heat transfer to farther distance of piece 3 that generates heat for indoor rapid heating up promotes user experience. Moreover, compared with the common axial-flow fan heater in the prior art, the wind power generated by the fan assembly 2 in the embodiment is not directly diffused indoors, but the wind power generated by the fan assembly 2 is fully utilized through the tapered part 4, so that the wind power is more concentrated, and the energy loss caused by hot air disturbance is reduced.
