Abstract

An accessory for use in a vacuum cleaner or a vacuum-cleaning conduit for collecting and holding liquid sucked up by the vacuum cleaner, comprising: a container having a reservoir for holding the liquid, a removable cover for said container and extending substantially horizontally thereover, means for dividing said container into said reservoir and a chamber above said reservoir and having a substantially horizontally extending plate, an inlet fitting connected to said cover for connecting the interior of sand reservoir to a hose leading to the suction nozzle of the vacuum cleaner or a vacuum cleaning conduit, said inlet fitting including a pipe extending vertically and having a lower end portion extending into said reservoir, an outlet fitting in said cover for connection to a hose leading to the body of the vacuum cleaner or vacuum-cleaning conduit and communicating with said chamber, at least one passage in said plate between said chamber and said reservoir, and a float-controlled valve including a float vertically guided on said lower end portion and a sealing plate loosely arranged on said float and adapted to close said passage to thereby shut off said chamber from said reservoir when the liquid in said reservoir reaches a predetermined level.

Claims

1. An accessory for use in a vacuum cleaner or a vacuum-cleaning conduit for collecting and holding liquid sucked up by the vacuum cleaner, comprising:

a container having a reservoir for holding the liquid, a removable cover for said container and extending substantially horizontally thereover, means for dividing said container into said reservoir and a chamber above said reservoir and having a substantially horizontally extending plate, an inlet fitting connected to said cover for connecting the exterior of said reservoir to a hose leading to the suction nozzle of the vacuum cleaner or a vacuum cleaning conduit, said inlet fitting including a pipe extending vertically and having a lower end portion extending into said reservoir, an outlet fitting in said cover for connection to a hose leading to the body of the vacuum cleaner or vacuum-cleaning conduit and communicating with said chamber, at least one passage in said plate between said chamber and said reservoir, and a float-controlled valve including a float vertically guided on said lower end portion and a sealing plate loosely arranged on said float and adapted to close said passage to thereby shut off said chamber from said reservoir when the liquid in said reservor reaches a predetermined level.

2. An accessory according to claim 1, wherein said vertical pipe is centered on said cover and said pipe includes means for clamping said dividing means to said cover.

3. An accessory according to claim 2, wherein said means on said vertical pipe is a shoulder.

4. An accessory according to claim 1, comprising a filter between said passage and said outlet fitting.

5. An accessory according to claim 1, comprising a baffle plate shielding and being disposed under the outlet fitting within said chamber.

6. An accessory according to claim 1, wherein said float is disposed on such a level that said sealing plate seals said passage when the liquid level in said container corresponds to about one third of the height of the container.

7. An accessory according to claim 1, wherein said float is guided externally along said lower end portion of said vertical pipe and wherein said sealing plate is an annular plate.
