FAN ASSEMBLY Russian patent published in 2015 - IPC F04D29/58 

FIELD: heating.

SUBSTANCE: invention relates to fan building and to a nozzle for a fan. A fan assembly includes a motor-driven impeller designed for formation of an air flow, at least one heater designed for heating of the first part of the air flow and a casing containing at least one outlet air hole meant for outlet of the first part of the air flow, and the first channel device intended to supply the first part of the air flow to at least one above said outlet air hole. For cooling of some part of the casing, the latter includes a device for deflection of the second part of the air flow from at least one above said heater and the second channel device intended to supply the second part of the air flow along the inner surface of the casing. Such second part of the air flow can be combined with the first part of the air flow inside the casing, or it can be discharged through at least one second outlet hole for air of the casing, preferably after the outer surface of the casing.

EFFECT: improved structure.
