Abstract

Humidifying apparatus includes a body comprising a chamber into which water is supplied by a water tank. An air flow is generated over water stored in the chamber, and a humidifying system humidifies the air flow with water from the chamber. Water in the chamber is irradiated by an ultraviolet radiation emitting lamp. The lamp forms part of a cartridge removably locatable within the body so that the lamp is received within an ultraviolet radiation transparent tube of the chamber. The body includes a plurality of supports for supporting the cartridge therebetween. Each support has a curved track for guiding movement of the cartridge towards the tube, the tracks being shaped to orient the cartridge for insertion of the lamp into the tube as the cartridge moves along the tracks towards the tube.

Claims

1. A humidifying apparatus comprising:

a body comprising a chamber;

a water tank for supplying water to the chamber;

an air flow generating device for generating an air flow over water stored in the chamber;

a humidifying device for humidifying the air flow with water from the chamber;

a cartridge removably locatable within the body, the cartridge comprising an ultraviolet radiation emitting lamp for irradiating water in the chamber, the chamber comprising an ultraviolet radiation transparent tube for receiving the lamp; and

at least one air outlet for emitting the air flow;

wherein the body comprises a plurality of supports for supporting the cartridge therebetween, each support comprising a curved track for guiding movement of the cartridge towards the tube, the tracks being shaped to orient the cartridge for insertion of the lamp into the tube as the cartridge moves along the tracks towards the tube.

2. The apparatus of claim 1, wherein the cartridge is slidable along the tracks.

3. The apparatus of claim 1, wherein the cartridge comprises a plurality of runners, each runner being locatable within a respective track.

4. The apparatus of claim 3, wherein the width of each track varies along the length of the track.

5. The apparatus of claim 4, wherein the width of each track increases along the length of the track.

6. The apparatus of claim 4, wherein the width of each track increases from a first width which is substantially equal to the width of its respective runner, to a second width which is substantially equal to the length of is respective runner.

7. The apparatus of claim 1, wherein the body comprises a bottom wall defining an aperture through which the cartridge is insertable into the body, and wherein each support is connected to the bottom wall of the body.

8. The apparatus of claim 7, wherein each track extends from the bottom wall of the body towards the chamber.

9. The apparatus of claim 7, wherein the longitudinal axis of the tube is substantially parallel to the bottom wall of the body.

10. The apparatus of claim 7, wherein the body comprises a panel for closing the aperture, and wherein the panel comprises a mechanism for urging the cartridge towards a position in which the lamp is inserted fully within the tube.

11. The apparatus of claim 7, wherein the humidifying device comprises a transducer, and wherein the transducer is removable from the body through the aperture.
