Air treatment apparatus
There is provided an air treatment apparatus including an air flow generator that is arranged to generate an airflow, a moisture source that is arranged to introduce water vapour into the air flow, a body that in use surrounds both the air flow generator and the moisture source, a water supply system that is arranged to provide water to the moisture source, the water supply system including a water tank assembly that is separable from the body, an interface sealing element that is arranged to form a seal between the water tank assembly and the body that prevents leakage of air into the body, an air supply feed that is arranged to convey air from within the body of the air treatment apparatus into the water tank assembly, and one or more air filter assemblies that are located upstream of both the moisture source and the air supply feed.
1. An air treatment apparatus comprising:
an air flow generator that is arranged to generate an air flow;
a moisture source that is arranged to introduce water vapour into the air flow;
a body that in use surrounds both the air flow generator and the moisture source, the body being arranged to support the moisture source;
a water supply system that is arranged to provide water to the moisture source, the water supply system comprising a water tank assembly that is separable from the body, the water tank assembly comprising:
a water tank, and
a tank-to-body connector that is disposed on the water tank assembly and that is arranged to separably connect to a corresponding body-to-tank connector provided on the body and through which water is conveyed from the water tank to the body;
an interface sealing element that is arranged to form a seal between the water tank assembly and the body that prevents leakage of air into the body;
an air supply feed that is arranged to convey air from within the body of the air treatment apparatus into the water tank assembly; and
one or more air filter assemblies that are located upstream of both the moisture source and the air supply feed.
2. The air treatment apparatus of claim 1 , wherein the interface sealing element is arranged to form a seal around an interface between the water tank assembly and the body.
3. The air treatment apparatus of claim 1 , wherein each air filter assembly comprises a filter sealing element that is arranged to engage the body of the air treatment apparatus to prevent air from passing around edges of the air filter assembly.
4. The air treatment apparatus of claim 1 , wherein the interface sealing element is arranged on the body-to-tank connector.
5. The air treatment apparatus of claim 1 , wherein the air supply feed is arranged to convey air from within the body into the water tank assembly through the tank-to-body connector.
6. The air treatment apparatus of claim 1 , wherein an interface between the water tank assembly and the body is formed between the tank-to-body connector and the body-to-tank connector.
7. The air treatment apparatus of claim 1 , wherein the interface sealing element is provided on the tank-to-body connector.
8. The air treatment apparatus of claim 1 , wherein one of the tank-to-body connector and the body-to-tank connector is biased towards the other of the tank-to-body connector and the body-to-tank connector.
9. The air treatment apparatus of claim 8 , wherein the body-to-tank connector is movably mounted to the body of the air treatment apparatus and comprises a resilient member that is arranged to bias the body-to-tank connector towards the tank-to-body connector.
10. The air treatment apparatus of claim 1 , wherein the water tank assembly is arranged to support the moisture source.
11. The air treatment apparatus of claim 10 , wherein the interface sealing element is arranged to form a seal between a surface of a water tank of the water tank assembly and a surface of the body.
12. The air treatment apparatus of claim 11 , wherein in use the interface sealing element is arranged to surround the moisture source.
13. The air treatment apparatus of claim 10 , wherein the air supply feed is arranged to convey air from within the body into the water tank assembly through an aperture provided in the water tank assembly, and wherein in use this aperture is surrounded by the interface sealing element.
14. The air treatment apparatus of claim 1 , wherein the water tank of the water tank assembly is provided with a tank opening and the water tank assembly further comprises a removable tank cap or cover that is arranged to fit over and thereby occlude the tank opening.
15. The air treatment apparatus of claim 14 , wherein the removable tank cap or cover comprises a tank cap sealing element that is arranged to form a seal against the water tank when the removable tank cap or cover is disposed on the water tank and thereby prevent leakage of air through the tank opening into the water tank.
