Problems solved by technology

For regenerative operation of the vacuum cleaner, the bypass air valve can also be used, but its opening cross-section is designed for suction and is therefore too small to ensure ideal cleaning of the dust filter and dust chamber

Embodiment Construction

[0025] figure 1 A vacuum cleaner 1 is shown, which is designed here as a portable hand-held vacuum cleaner, for example. The vacuum cleaner 1 has a housing 13 on which a handle 14 is formed, on which a user can guide the vacuum cleaner 1 over the surface to be cleaned during suction operation. Furthermore, a switch 15 is formed on the housing 13 , via which a motor 19 of the vacuum cleaner 1 can be switched on and off. The motor 19 is used to operate the fan 5, which generates a flow of suction air for taking suction from the surface to be cleaned. A suction nozzle 2 is also formed on the housing 13 of the vacuum cleaner 1 , through which suction material enters the vacuum cleaner 1 . A dust collection chamber 4 with a dust filter 3 is connected downstream of the suction nozzle 2 in the suction direction. A fan 5 with a motor 19 is then provided. The dust filter 3 separates the dust collection chamber 4 containing the inhaled material from the clean air flow path 6 (for ex...

Abstract

The invention relates to a vacuum cleaner (1) having a suction nozzle (2), a dust collection chamber (4) equipped with a dust filter (3) and a fan (5), wherein the suction nozzle (2) is directed towards conveying suction to The suction operation in the dust chamber (4) is connected to the fan (5) with the dust chamber (4) connected in between, where the clean air flow path (6) is between the dust filter (3) and the fan (5 ) with a bypass air intake (7), and wherein the dust chamber (4) has a regeneration interface (8) for connection to the base station (16) for regenerative operation, for the ) is transported from the vacuum cleaner (1) to the base station (16). In order to further optimize the regeneration effect, it is proposed that the bypass air intake (7) has a variable opening cross-section for feeding the bypass air into the clean air flow path (6) based on the already opened state, wherein the opening cross-section The magnitude of the cross-section can be adjusted from a defined first non-zero magnitude to a defined second non-zero magnitude depending on the switchover of the vacuum cleaner (1) between suction and regeneration operation.

Description

technical field [0001] The invention relates to a vacuum cleaner with a suction nozzle, a dust collection chamber equipped with a dust filter, and a fan, wherein the suction nozzle is operated with a dust collection chamber connected therebetween for suction operation for conveying suctioned matter into the dust collection chamber connected to the fan, where the pure air path between the dust filter and the fan has a bypass air intake, and where the dust chamber has a regenerative interface for connection to the base station for regenerative operation, for the The aspirated material in the dust chamber is transported from the vacuum cleaner to the base station. Background technique [0002] Regenerative vacuum cleaners of the above-mentioned type are known in the prior art. This type of vacuum cleaner has a dust filter designed as a so-called permanent filter, which is not replaced when it is completely filled with dust - or earlier if necessary - The normal suction direct...
