Abstract

The invention relates to a carpet cleaning device (1), especially a sweeper or a carpet brush, with a device for removing dust, soiling particles or the like from a surface to be cleaned, especially sweeping units, preferably in the form of sweeping brushes (2) and a collecting chamber (3) for soiling removed. In order to obtain easy and especially hygienic operation with the simplest possible structure, the invention proposes that the cleaning device (1) be connectable to a suction device (12) to empty the collecting chamber (3).

Description

The invention relates to a cleaning device, in particular a sweeper or a carpet sweeper, with a device for collecting dust, dirt or the like. Of a surface to be cleaned, in particular Sweeping elements preferably in the form of brushes, and a receiving chamber for the dirt.

Such cleaning devices are used as carpet sweepers known in various configurations.

E.g. is to refer to the German utility model DE-U-19 09 382.

Carpet sweepers of this type are already included an electric drive has become known, for example. to the German utility models DE-U-75 34 321 and DE-U-75 36 434 is to be referred.

Further in the prior art is also on DE-A-29 43 210 and US-A-5 018 240.

In such carpet sweepers, it is also known the collected dirt in a separate holder to collect. This can be used to empty the intake be removed from the device altogether.

Furthermore, vacuum cleaner devices are known, for which purpose only referred to, for example, DE-A-39 11 580 becomes. Here, the dirt is sucked in one Dust bag collected after opening the vacuum cleaner is removable and can be disposed of altogether.

There is a need for a cleaning device such as in particular to specify a carpet sweeper that the one hand not as complex and large as a vacuum cleaner is trained, but on the other hand if possible same hygienic advantages in terms of disposal of the collected dirt. The technical The problem is therefore given by a To further develop the cleaning advice of the type specified above and design that with the simplest possible Structure nevertheless an advantageous and particular one hygienic handling is given.

This technical problem is solved in the subject of claim 1, it being based on the fact that the cleaning device Has means by means of which the cleaning device for emptying the receiving chamber with an external suction device can be interconnected.

The suction device can For example, be a common vacuum cleaner. This is a Cleaning device created, its inclusion as it were represents an interim storage facility for the collected dirt. The receptacle itself is preferably not openable or removable from the device. The emptying can only by connecting a suction device, in particular the usual vacuum cleaner. In advantageous Way, this cleaning device can have a used for a long period of time and several cleaning processes the suction device without it being necessary to connect. If the suction device is used anyway, can also drain the cleaning device hereby be made. Even the dirt that has been collected by the cleaning device in the usual way in the dust bag of a vacuum cleaner transported and can then all in all with the dust bag be disposed of in the usual way. An expensive one Device for attaching your own dust bag or the like on the cleaning device in question itself is not necessary. Here, the cleaning device motor-operated or only hand-operated be. Engine operation can be used in particular for driving the cleaning brushes may be provided. In another Embodiment of the invention provides that the Receiving chamber has a suction port for connection the suction device. The suction port is therefore immediate coupled to the receiving chamber. As long as the suction device is not connected, comes the suction nozzle no meaning too. In detail, the reception chamber be designed such that following one Inlet funnel, which in the case of sweeping brushes in the tangential direction of ejection of the sweeping brushes is, a trough-like receiving groove is formed. This receiving channel extends further preferably transverse to a direction in which the cleaning device usually move for cleaning purposes is. It is also advantageous to the receiving channel in extending substantially above the inlet funnel to arrange. Through the inlet funnel, the dirt particles thrown off by the brushes steered and deflected above, so that they then into the Receiving gutter fall. In a cross section is the Compare the receiving chamber with a snail shell. The inlet funnel also expediently extends essentially over the length of the receiving channel and at the same time also over the length of the sweeping brushes. The suction nozzle can advantageously in open a floor of the receiving channel.

Is shown and described - initially with reference to Fig. 1- a cleaning device 1 in the form of a carpet sweeper. The cleaning device here has brushes 2, of which usually two individual brushes side by side are arranged on a central drive. Continue an electric motor is provided, which is not in detail is shown for driving the sweeping brushes 2.

The cleaning device 1 has a receptacle 3, in which dirt particles, dust, etc., which by means of Sweeping brushes 2 swept up, collected. In Fig. 1 is schematically in a receiving channel 4 of the Receiving chamber 3 accumulated dirt 5 shown.

Next is the receiving chamber 3 with a suction port 6 formed in a bottom of the receiving groove 4th flows. The bottom of the receiving channel 4 is therefore in the area of the suction nozzle 6 partially interrupted. Of the In the exemplary embodiment, suction nozzle 6 can be in the center with respect to a transverse extension (extension in the direction of the longitudinal axes of the sweeping brushes 2) of the receiving chamber 3 be formed, but it can also be, for example or assigned to the ends at both ends the receiving chamber 3 be formed and in contrast for example, the bottom of the receiving channel would be 4 then with double-sided arrangement twice each a suction nozzle 6 interrupted. The suction nozzle can also directly connected to one or both ends be. Here is an enforcement of Soil not required.

The receiving chamber 3 also has an inlet funnel 7, which is arranged in the direction of throw of the sweeping brushes 2 is. The inlet funnel 7 is in its mouth area 8 formed with an opening height that is about corresponds to a radius of the carpet sweeping brushes 2. He then tapers and is curved up to a height h, in which an inner trough wall 9 den Conclusion to the receiving channel 4 forms. In the embodiment passes through the suction nozzle 6 through the inlet funnel 7 approximately in the middle in relation to a longitudinal or Transverse extent of the inlet funnel 7 and the receptacle 3 in total. The assertive ends in this area Suction nozzle 6 in the inlet funnel 7 as it were Flow divider.

It is also important that the receiving channel 4 above of the inlet funnel 7 and to an opening of the Inlet funnel 7 is arranged sunk. The receiving channel 4 is roughly assigned to one upper cross-sectional half of a brush 2.

As from the cross-sectional view according to FIG. 1, however also the cross-sectional representations of FIGS. 5 and 6 can be seen, the receiving funnel 7 is together with the receiving channel 4, as it were, like a snail shell designed.

From the representations of FIGS. 1 and 2 is still can be seen that the suction nozzle 6 in a suction line 10 opens out with a connector 11 with a suction device shown only schematically, namely in particular a vacuum cleaner 12 can be connected. Of the Connector 11 is closable.

It is also preferably provided in the drawing however, not shown in detail that the mouth opening 8 of the inlet funnel 7 can be closed by a blind is. This can cause a fall out of collected dirt, for example when the Device.

The design of the receiving chamber 3 is further in detail 3 to 6 can be seen.

As can be seen in particular from the cross-sectional representation Fig. 5 shows is also the connection of the suction channel 6 together with the assigned part of the receiving channel 4 and the upper substantially circular arc End 13 formed like a worm gear. Means Locking means 14 can be the receiving chamber 3 in the cleaning device 1 be locked. It is particularly preferred that the receiving chamber 3 cannot be released operationally is arranged in the cleaning device.
