Description

OBJECT OF THE INVENTION

The invention, as stated in the title of the present specification, relates to cleaning equipment for urban waste bins and the like which contributes, to its intended use, advantages and features, which are described in detail further on, which imply an improvement in the current state of the art.
The object of the present invention lies in a cleaning equipment which, especially designed to clean urban waste bins or other containers or similar elements, is distinguished by essentially comprising a waterproof bag to cover the waste bin and a brush to clean and apply steam therein, achieving, among other advantages, more effective cleaning with less water consumption and avoiding splashes and unwanted inconvenience to passers-by.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention falls within the industry sector dedicated to the manufacture of equipment, appliances, accessories and cleaning devices, focusing particularly on those in urban areas.

BACKGROUND OF THE INVENTION

Currently, in most municipalities, to clean waste bins, equipment with a KSrcher-type pressurized water cleaning system, is normally used, consisting of a gun connected to a tank supported on a vehicle and with which water or water with detergent is applied under high pressure on the waste bin to be cleaned. Furthermore, in the case of tilting waste bins, it is usually necessary to hold them upside down, for example with a bar or the like that acts as a stop, to apply pressurized water therein and make the dirt fall out of the bin.
The problem with this system, in addition to a large consumption of water and the fact that the vehicle is not always suitable for passing through narrow streets or sidewalks, is mainly the inconvenience it represents for other passers-by, since a large amount of water is splashed and everything around the waste bin gets wet, including vehicles, facades, etc. Furthermore, the problem of water splashes is even greater, if possible, when it is windy, since the jet of water can wet pedestrians, even when they are many meters away from the operator who handles the pressurized water gun.
On the other hand, if the compressor turns off or has any operating or heating problems, the gun can no longer be used. Finally, another drawback is the use of boilers to carry out deeper cleaning of stains, graffiti or others, where if the boiler does not work correctly, they cannot be removed.
The objective of the present invention is, therefore, the development of a new equipment and system for cleaning waste bins to avoid these drawbacks.
Furthermore, and as a reference to the current state of the art, at least the applicant is unaware of the existence of any other cleaning equipment for urban waste bins and like, or of any other invention of similar application, which presents technical and structural features that are the same or similar to those presented by that which is claimed herein.

DESCRIPTION OF THE INVENTION

The cleaning equipment for urban waste bins and the like proposed by the invention is configured as the ideal solution to the aforementioned objective, the characterizing details that make it possible and that distinguish it being conveniently included in the final claims that accompany this description.
Specifically, what the invention proposes, as noted above, is cleaning equipment that is especially designed to clean urban waste bins or other containers or similar urban elements, which is essentially distinguished by comprising a waterproof bag, sized to completely cover at least one waste bin and a brush to clean and apply steam therein, achieving, among other advantages, more effective cleaning with less water consumption and preventing splashes and unwanted inconvenience to passers-by.
More specifically, the equipment of the invention comprises at least the following elements:

A plastic bag or other waterproof material, which can be reusable and has an access hole to allow the handle of an applicator element to pass through it;
An applicator element, i.e. sprayer, suitable for introducing steam and spraying cleaning or disinfection products, from a container tank with means to produce said steam and/or spray; and
A brush with radial plastic bristles which, optionally, is incorporated into the nozzle itself of the steam applicator element.

In addition, the equipment optionally provides for the inclusion of a vacuum cleaner with a brush at the end of the suction nozzle.
Therefore, the steps of the bin cleaning process are as follows:

Firstly, after placing the bag on the waste bin arranged vertically, without tilting, and so that the mouth of the bag is open downwardly, practically touching the ground, the inside is sprayed, introducing the nozzle of the applicator through the opening provided for this purpose at the bottom of the bag and which is now located at the top of the bin.
Next, steam is applied to the inside of the waste bin, causing the dirt to soften.
Then, the inside of the waste bin is brushed.
In this process, water from the steam falls onto the support or crossbar and legs of the waste bin, which also softens any dirt they may have.
Once the waste bin is cleaned with steam, and after removing the bag, the interior solid waste is vacuumed.
Preferably, a small brush is attached to the suction nozzle with which the crossbar and support legs of the bin are scrubbed, at the same time vacuuming up any solid and liquid waste that may have been left impregnating said support or the ground under the waste bin.

The equipment of the invention provides multiple advantages over systems currently used for the same purpose, where the following stand out particularly:

The water vapor is concentrated therein, so that it helps, together with the brushes, to clean and disinfect the waste bin without having to tilt it.
Significant water savings and disinfectant product savings are achieved, especially on windy days.
It is a silent system, since the steam and suction are produced by an electrical system.
The size of the equipment is very small, and it can be incorporated into a manual push cleaning cart, so it may gain access anywhere, even on sidewalks less than one meter wide and narrow streets in historic downtown areas, making hardly any noise at all.
The size of the bag will be variable to adapt to different types or sizes of waste bins or containers, and it may also consist of an extendable bag to adapt its dimension to different needs, for example twin waste bins, which are installed in pairs.
It allows the cleaning of graffiti or stains with a retractable gun with water or steam.
Thanks to the bag, there is no splashing on pedestrians or elements adjacent to the waste bin.
