DE8803226U1 - Cleaning device for toilet and urinal bowls - Google Patents

Description

The invention relates to a cleaning device for toilet and urinal bowls.

Cleaning toilet and urinal bowls, especially in larger toilet facilities such as those found in public toilets, guest houses, hotels, schools, hospitals, etc., is a laborious and unpleasant task when using the hand cleaning brushes known to date.

The invention is based on the object of

To create an improvement that enables quick, thorough and pleasant cleaning of even large numbers of toilet and urinal bowls.

This object is achieved according to the invention by the cleaning device characterized in claim 1.

The invention thus creates a device that can be easily moved over a pool to be cleaned and then allows convenient cleaning of the pool with the help of the telescopically movable and all-round pivoting cleaning brush, which has a motor drive.

Advantageous embodiments of the device according to the invention are the subject of the subclaims, which speak for themselves and are so easily understandable that no further explanation is required. The only thing to mention in detail about the claimed design of the cleaning brush is that the dense, closed cover bristle ring made of soft bristles serves as a splash guard or splash guard against water stirred up by the rest of the brush in the basin to be cleaned and the other bristle rings with different bristle lengths and bristle inclination angles enable intensive and complete cleaning not only of the easily accessible surfaces of the basin to be cleaned, but also of corners, angles, in the drain and under sink rims.

An embodiment of the device according to the invention is shown by way of example in the accompanying drawings and is described in detail below. In the drawings:

Axial section.

According to Fig. 1, the cleaning device has a mobile bridge-like frame 1, which consists of a U-shaped base frame 1a provided with castors and a support bracket 1b connected to it and projecting upwards.

In the middle of the support bracket Ib, a telescopic arm 11 is pivoted in all directions by means of a ball joint 8, the downwardly extendable part of which has a built-in motor mount 6 with an electric motor 7 and carries a cleaning brush 5 attached to its lower end. The

An operating handle 9 with a switch handle 10 arranged thereon for switching the electric motor 7 is attached to the lower telescopic arm section.

A control box 3, which is also attached to the support bracket 1b of the frame 1, contains a motor control which ensures that the motor 7 changes its direction of rotation each time it is switched on again via the switch handle 10.

The cleaning brush 5 is, as shown by the 15 arrows, longitudinally displaceable and ^pivotable in all directions and can be reversed in its direction of rotation.

The electrical supply cable 4 for the electric motor can run inside the frame 1 designed as a tubular frame.

The cleaning brush 5 shown in Fig. 2 represents a concrete embodiment with the following features:

Water is stirred up by the rotating movement of the cleaning brush. In the specific example, the bristles have a length of approx. 80 mm (measured from the brush body) and are inclined downwards by approx. 10° (relative to the brush rotation axis, which is considered vertical).

The next two bristle rings B and C each have bristle lengths of approx. 60 mm and their bristles are inclined upwards by approx. 6° and 12° respectively.

The next bristle ring G has a bristle length of approx. 70 mm and a bristle inclination of approx. 15° upwards.

The bristles of the bristle ring H are approx. 40 mm long and are inclined downwards by approx. 20°. The bristle ring I, with a bristle inclination of approx. 50° downwards, has longer bristles, namely approx. 50 mm long.

The other bristle rings K, L and M each have bristles that are approx. 30 mm long and bristle inclination angles of 50° or 80° downwards or parallel to the axis of rotation (bristle ring M).

Of the bristle rings B to H, the bristle rings F and I consist of soft bristles, the remaining bristle rings of hard bristles.

While, as already mentioned, the cover bristle ring A is a circumferentially tightly closed bristle ring, the other bristle rings B to M each consist of about 7 to 12 individual bristle bundles distributed around the circumference of the brush body.
