Description

Field of invention

[0001] The invention relates to cleaning technology, in particular hand-held electric devices for cleaning the joints of floor coverings indoors and outdoors, which are equipped with a collection device for collecting loosened dirt, weeds or deposits. Background of the invention

[0002] Electric grout cleaners with rotating brushes are known from the prior art; these remove dirt or growth from grout lines. The loosened dirt usually remains on the floor surface and must subsequently be swept or vacuumed up manually.

[0003] Some well-known devices have rigid collection boxes that hold the loosened dirt. However, such boxes are limited in volume, difficult to clean, not space-saving to store, and increase the weight of the device. Furthermore, their rigid design makes flexible emptying and storage difficult.

[0004] Therefore, there is a need for a joint cleaning device that enables reliable removal of the loosened dirt, but is lighter, more flexible and ergonomically easy to handle. Summary

[0005] It is an object of the invention to provide an electric grout cleaner that enables simple and reliable dirt removal, has a larger capacity, is easier to handle and clean, and provides additional comfort and safety features for the user.

[0006] The electric joint cleaner according to the invention comprises a housing (1) with a handle (2) and a switch (4) arranged thereon, a lower brush head (5) with a rotating brush (6) and one or more wheels (7) for guiding along joints.

[0007] A collection device, in particular in the form of a flexible collection bag (8), is arranged on the brush head (5). The collection bag (8) is detachably connected to the brush head (5) by means of fastening means (9) and may have a discharge opening (10) and a stiffening element (11).

[0008] The dirt can be introduced into the collection bag (8) via an air duct (12) that utilizes the airflow generated by the brush (6). Alternatively or additionally, the dirt can be introduced by the centrifugal force of the brush (6), so that the collection bag (8) is filled even without an additional airflow. A filter insert (13) can be provided as an option.

[0009] To protect the collection bag (8), a protective element (16) is provided which is arranged below the collection bag and prevents the bag from touching the ground and being damaged during use.

[0010] The collection bag (8) can be made of textile, tear-resistant or washable material and may be equipped with a viewing strip (14). Alternatively or additionally, a rigid collection box (15) can be provided.

[0011] Further features include telescopic handles, soft-grip handles, battery operation, LED lighting, splash guards, noise-dampening materials, and the use of reusable or disposable bags, the latter also made of compostable material. Fig. Figure 1 shows a perspective view of a grout cleaner with a collection bag. Fig. Figure 2 shows a detailed view of the brush head with wheel and intake opening. Fig. Figure 3 shows the collection bag in a detached view. Fig. Figure 4 shows a schematic section through the brush head with air guide channel. Fig. Figure 5 shows a variant with a rigid collection box.

[0012] Fig. Figure 1 shows an electric grout cleaner with a housing (1) that has a handle (2) with a switch (4) at its upper end. The electric motor in the brush head (5) is powered via the mains connection cable (3). The brush head (5) is equipped with a rotating brush (6) that is guided along a grout line by one or more wheels (7). The flexible collection bag (8) is attached behind the brush head (5). The collection bag (8) is secured by fasteners (9) and can be removed without tools. A stiffening element (11) at the top ensures that the bag remains open and that the dirt is reliably collected. A discharge opening (10) is located at the rear.

[0013] Additionally, the collection bag (8) can be connected to the housing (1) or handle at the rear via a retaining element (17). This retaining element (17) prevents the collection bag (8) from touching the ground during use and supports the function of the protective element (16).

[0014] Fig. Figure 2 shows the connection between the collection bag (8) and the brush head (5). An air duct (12) directs the airflow generated by the brush into the collection bag. Alternatively or additionally, the dirt can be introduced by the centrifugal force of the brush (6). A filter insert (13) can optionally be integrated. A protective element (16) is also provided, which is advantageously positioned below the lower edge of the bag. This protective element (16) serves to prevent the collection bag (8) from resting on or dragging on the ground, especially when the device is tipped over, and thus protects the material of the collection bag from damage.

[0015] Fig. Figure 3 shows the collection bag (8) in a detached view. It is made of tear-resistant textile material, can be fully washed and has a viewing strip / fill level indicator (14).

[0016] Fig. Figure 4 shows a cross-section through the brush head (5) of the air guide channel (12), which ensures targeted filling of the collection bag (8). Additionally, dirt can also be introduced here solely by the centrifugal force of the brush (6).

[0017] Fig. Figure 5 shows an alternative embodiment in which a rigid collection box (15) is attached instead of the collection bag (8).
