Problems solved by technology

[0005] On the one hand, the pressure surge generated by the brief reversal of the usual air flow is uncomfortable for the user of the vacuum cleaner, and on the other hand, the pressure surge impairs the suction capacity of the vacuum cleaner

Embodiment Construction

[0024] Figure 1a with Figure 1b A vacuum cleaner 1 with a device 2 for compensating air pressure surges is shown according to a first embodiment.

[0025] Here, the vacuum cleaner 1 essentially comprises a suction head 3 , a storage container 4 and an air intake device 5 .

[0026] from Figure 1a to Figure 3 It can be seen that the suction head 3 again essentially comprises a filter 6 , a filter cleaning device 7 and a turbine 8 .

[0027] The turbine 6 is used to generate a vacuum by means of which the first air flow LS1 flows into the interior of the vacuum cleaner 1 . Via the first air flow LS1 , dust particles and dirt particles can be absorbed and transported into the storage container 4 for storage.

[0028] The filter 6 serves to filter out dust and dirt particles from the first air flow HS sucked in by the vacuum cleaner 1 and thus protects the turbine 8 in particular from dust and dirt.

[0029] The filter cleaning device 7 serves to clean the filter 6 by brief...

Abstract

The invention relates to a device for a vacuum cleaner, for compensating pressure surges, through which device a first air flow can flow in a first flow direction and a second air flow can flow in a second flow direction. The device contains a main body having a first flow cross-sectional area and at least one flow resistance element, at least part of the free end of which projects in the second flow direction to create a second flow cross-sectional area, the first flow cross-sectional area being greater than the second flow cross-sectional area, such that the second air flow flowing in the second direction is reduced. The invention also relates to a vacuum cleaner hose comprising a device for a vacuum cleaner for compensating pressure surges. The invention further relates to the vacuum cleaner comprising a device for the vacuum cleaner for compensating pressure surges.

Description

technical field [0001] The invention relates to a device for compensating air pressure surges for a vacuum cleaner, through which a first air flow can flow in a first flow direction and a second air flow can flow in a second flow direction. equipment. [0002] Furthermore, the invention relates to a vacuum cleaner hose with a device for compensating air pressure surges for the vacuum cleaner. [0003] Furthermore, the invention relates to a vacuum cleaner with a device for compensating air pressure surges for the vacuum cleaner. Background technique [0004] Prior art vacuum cleaners used in conjunction with dust-generating power tools, especially hammer drills and saws, typically have filter cleaning systems. In this case, filter cleaning can be accomplished by briefly reversing the normal air flow through the filter to be cleaned. The air flow that flows in the opposite direction to the normal flow briefly creates a pressure surge that causes accumulated dust and dirt t...
