Equipment trolleys for cleaning purposes and Methods of cleaning floors

The invention relates to an equipment trolley for cleaning purposes, which carries a plurality of containers and shelves arranged one above the other on a chassis with a structure.
15th

In a known equipment trolley of this type, the chassis and the structure consist of a tubular frame. Of the Tubular frame is jurc attaching different brackets prepared for containers and bowls as well as shelves. The lower container, which can be placed on the chassis, takes the Cleaning solution. By repeatedly dipping a scrubber-like mopping device wrapped with mop covers the cleaning solution can be taken from the container and distributed on the floor to be cleaned. Dureh the repeated immersion of the mopping device in the cleaning solution it becomes increasingly polluted. Because of the increasing contamination of the cleaning solution, the Cleaning effect more and more. In addition, the cleaning solution is not being used optimally. In addition, the Cleaning hospital rooms runs the risk of being of one

-δι sick people in the other sick room because of the Continued use of the cleaning solution will spread bacteria.

In order to reduce the risk of the cleaning of sick rooms To lessen the spread of bacteria from one room to another room, it is common for everyone Room to use new mop covers. Such a cleaning process is time-consuming because it is usually off Existing textile, expensive mop covers have to be washed out after each use in the laundry. Furthermore This process is cumbersome because the cleaning woman has a large number of new and used mop covers must lead. Finally, it cannot be avoided that when the mop covers are replaced with the cleaning solution comes into contact. Since the cleaning solution is aggressive to the skin, it often leads to skin damage.

The invention is based on the object of providing a device dare to create whose ease of use is optimal and which enables faster and better cleaning results.

According to the invention, this object is achieved with an equipment trolley of the type mentioned at the outset in that a can be filled with cleaning liquid (disinfectant solution) Tank with drain cock above a dipping vat ·· for a scrubber-like mopping device equipped with a sponge is arranged, and that the dip tank can be emptied into a lower-lying collecting basin, into which the liquid contained in the sponge and squeezed out by a press located above the collecting basin or can be drained indirectly via a drain.

The spatial assignment of the various parts of the equipment trolley allows the floor to be cleaned ergonomically with a compact design of the equipment trolley. So the Tauchv / anne - Niteiner amount of liquid to be filled that just is necessary for cleaning a certain area, e.g. for the area of a room. Should there be a residue of cleaning fluid is still in the dip tank, it is drained into the collecting basin. The dip tank then stands for the recording new cleaner cleaning fluid is available again. The press allows after each application of cleaning fluid squeeze the sponge on the floor and before each new immersion in the cleaning liquid, so that the cleaning liquid in the dip tank is not contaminated by dirty cleaning liquid. The possible squeezing out of the sponge before immersion in the liquid has the further advantage that the sponge more clean cleaning fluid for the immersion pan. remove than would be possible without squeezing. In addition, it is guaranteed that the cleaning lady does not longer with the cleaning fluid that is aggressive to the skin comes into contact because the sponge is squeezed out by the press and the covers are changed completely omitted.

The immersion tub is space-saving, easy to assemble and easily accessible _when it is tilted so that it can be filled with the cleaning fluid in its first position and emptied in its second position.

the press is preferably between the tank and the collecting basin and arranged behind the folded up touch panel. There the press is only used when the .TRUchwmne is in use but this is lowered in the used position

works, the press is easily accessible for the operator. With this arrangement the press does not need a special one Drain for contaminated liquid to be provided because the squeezed out liquid immediately

In the collecting tank runs ^:

The drinking bowl can also be designed in such a way that, in the folded-up position, it does not only hold the press but also covers the drain cock of the tank. Since it is not necessary for the mopping device to drip to wet the floor If the cleaning fluid transfers to the floor, it is useful if the towel rails are above the maximum Has grate lying on the liquid level for squeezing out and / or wiping off the sponge of the mopping device. Preferably the grate is formed in the inside of the sloping front wall of the immersion varine. The back wall the immersion tub should have wall parts inclined towards a pouring channel so that the cleaning liquid is tipped out towards the drainage channel results in a suction, the dirt particles in the immersion tub when Tipping out due to the resulting suction.

The press can consist of a stationary grate and a movable ram arranged above the grate, which is preferably guided and can be operated by hand via at least one toggle lever. For ergonomic work both To ensure for both right-handed and left-handed people, one leg of each knee lever is connected across the Carriage extending shaft attached, on each end of which a hand lever can be slipped.
