Abstract

A cleaning appliance includes a main body and a collecting chamber releasably held on the main body. The collecting chamber includes a closure member which is movable between a closed position and an open position in which the collecting chamber can be emptied and an actuating member adapted and arranged to release the collecting chamber from the main body and, when the collecting chamber is released from the main body, to release the closure member from the closed position. By providing such an arrangement, a single actuating member can be used to release the collecting chamber from the main body of the cleaning appliance and also to open the closure member to empty the collecting chamber. A single actuating member is less complex, requires less space and is more intuitive for a user to operate.

Claims

1. A cleaning appliance comprising:

a main body, and

a collecting chamber releasably held on the main body, the collecting chamber comprising,

a closure member which is movable between a closed position and an open position in which the collecting chamber can be emptied, and

an actuating member comprising a user operable button,

wherein the user operable button is depressible toward a bottom of the collecting chamber to release the collecting chamber from the main body when the collecting chamber is held on the main body, and

wherein the user operable button is depressible toward a bottom of the collecting chamber to release the closure member from the closed position when the collecting chamber is not held on the main body.

2. A cleaning appliance as claimed in claim 1, wherein the actuating member forms part of a catch which holds the collecting chamber on the main body.

3. A cleaning appliance as claimed in claim 2, wherein the actuating member comprises a first part which forms part of the catch and includes a user-operable button, and a second part which is adapted and arranged to release the closure member.

4. A cleaning appliance as claimed in claim 3, wherein the actuating member further comprises a displaceable member which, in a first position, couples the first and second parts of the actuating member, and in a second position, decouples the first and second parts.

5. A cleaning appliance as claimed in claim 4, wherein the main body comprises a projection to displace the displaceable member from the first position to the second position when the collecting chamber is held on the main body.

6. A cleaning appliance as claimed in claim 4, wherein the displaceable member is rotatable between the first and second positions.

7. A cleaning appliance as claimed in claim 3, wherein the closure member further comprises a catch and the second part is adapted and arranged to urge the catch to release the closure member when the actuating member is operated when the collection chamber is removed from the main body.

8. A cleaning appliance as claimed in any one of the preceding claims, wherein the cleaning appliance is a vacuum cleaner.

9. A cleaning appliance as claimed in claim 8, wherein the vacuum cleaner incorporates a cyclonic separator.

10. A cleaning appliance as claimed in claim 9, wherein the cyclonic separator comprises an upstream cyclone separator having an upstream collector and a downstream cyclone separator having a downstream collector, both collectors being arranged within the collecting chamber.

11. A cleaning appliance as claimed in claim 10 wherein deposited dirt and dust within the each of the upstream and downstream collectors can be emptied simultaneously when the closure member is released.

12. A cleaning appliance comprising:

a main body, and

a collecting chamber releasably held on the main body, the collecting chamber comprising,

a closure member which is movable between a closed position and an open position in which the collecting chamber can be emptied, and

a depressible member,

wherein the depressible member is depressible in a fixed direction to release the collecting chamber from the main body when the collecting chamber is held on the main body, and

wherein the depressible member is depressible in the same fixed direction to release the closure member from the closed position when the collecting chamber is not held on the main body.

13. A cleaning appliance comprising:

a main body comprising a displacement projection, and

a collecting chamber releasably held on the main body, the collecting chamber comprising,

a closure member which is movable between a closed position and an open position in which the collecting chamber can be emptied,

an actuating member which is depressible both to release the collecting chamber from the main body and, when the collecting chamber is released from the main body, to release the closure member from the closed position, and

a connecting device, comprising a first part, a second part, and a displaceable member located between the first part and the second part, wherein a first distal end of the first part of the connecting device is proximate to the actuating member and a second distal end of the first part of the connecting device is proximate to the displaceable member, and a first distal end of the second part of the connecting device is proximate to the displaceable member and a second distal end of the second part of the connecting device is proximate the closure member,

wherein when the collecting chamber is not held on the main body, the displaceable member is configured to transmit a downward force applied to the first part of the connecting device by the actuating member to the second part of the connecting device, which then applies the force to release the closure member, and

wherein when the collecting chamber is held on the main body, the displacement projection contacts and displaces the displaceable member to prevent the downward force from being transmitted from the first part of the connecting device to the second part of the connecting device, and to thereby prevent the closure member from being released when the actuating member is depressed.
