Abstract

A fan assembly includes a body and an air outlet connected to the body. The body includes an air inlet comprising a plurality of apertures formed in an outer casing of the body, an impeller and a motor for driving the impeller to generate an air flow which passes along an air flow path extending from the air inlet to the impeller, a drive circuit for actuating the motor, the drive circuit being connected to the outer casing, and a panel for shielding the drive circuit from the air flow passing along the air flow path. The drive circuit includes a connector for connecting the drive circuit to a power cable, the connector being located within the outer casing. The outer casing includes an aperture through which the power cable is inserted to connect the cable to the connector, The panel includes a drain located beneath the connector.

Claims

1. A fan assembly comprising a body and an air outlet connected to the body, the body comprising:

an air inlet comprising a plurality of apertures formed in an outer casing of the body;

an impeller and a motor for driving the impeller to generate an air flow which passes along an air flow path extending from the air inlet to the impeller;

a drive circuit for actuating the motor, the drive circuit being connected to the outer casing; and

a panel for shielding the drive circuit from the air flow passing along the air flow path;

wherein the drive circuit comprises a connector for connecting the drive circuit to a power cable, the connector being located within the outer casing, the outer casing comprising an aperture through which the power cable is inserted to connect the cable to the connector, and wherein the panel comprises a trough located beneath the connector and in a form of a recessed section of the panel with a drain located in a lowermost part of the trough.

2. The fan assembly of claim 1, comprising an annular air inlet member for guiding the air flow towards the impeller, and wherein the drive circuit extends at least partially about the air inlet member.

3. The fan assembly of claim 2, wherein the panel is arcuate in shape.

4. The fan assembly of claim 1, wherein the panel comprises a base and a side wall upstanding from a periphery of the base.

5. The fan assembly of claim 1, wherein the panel and the drive circuit are connected to a common part of the outer casing.
