Abstract

The invention relates to an automatic toilet-cleaning system, mainly designed for the automatic cleaning of toilets installed in public areas, in large companies and in public institutions, with the essential aim of regularly cleaning the toilet, maintaining said toilet in perfect conditions of use, without any intervention by personnel, by means of manual or automatic actuation. This negates the necessity of the unpleasant task of having to manually clean, on a fairly frequent basis, toilets that are frequently used, such as those installed in public places, in large companies and in public institutions. To this end, the system comprises an enclosure that is mobile in relation to a stationary structure. Said enclosure is retracted in a first, idle position, the toilet remaining accessible for normal use, and in a second, working position, it is moved over the toilet in order to perform a cleaning cycle.

Description

AUTOMATIC TOILET CLEANING SYSTEM DESCRIPTION OBJECT OF THE INVENTION

The following invention, as expressed in the statement of the present specification, refers to an automatic toilet cleaning system, being primarily intended for automatic cleaning of toilets installed in public places, in large companies and public bodies , having as an essential objective to perform a regular cleaning of the toilet keeping it in perfect conditions of use, without the intervention of any personnel, with manual or automatic operation.

In this way, the sometimes unpleasant task of having to manually clean, with a certain frequency, those toilets that have frequent use, such as toilets installed in public places, in large companies and public bodies, is avoided.

Another important object is that the proposed cleaning system allows the application of products that, to prevent the spread of certain diseases, such as aureginous pseudomonas, staphylococcus aureus, enterococcus hirae, escherichia coli, etc.

In addition, it has the added advantage that in the execution of the cleaning a cabin is defined in which the toilet is left, effecting a three-dimensional cleaning of the same and its contour.

SCOPE

This report describes an automatic system for cleaning toilets, being applicable for cleaning toilets installed in public places, in large companies and public bodies, which have frequent use.

In this way, it is of special application in those public services in which the toilets are located in a small enclosure without any other sanitary element, such as service areas, airports, bus stations, train, etc. Likewise, it is also applicable in airplanes, trains, campsites, factories, restaurants, etc.

In addition, the system can be adapted to a portable toilet, so that it can be used in very different places during the necessary time, and, thus, it could be temporarily installed in large works for the operators of the same and in very different events in which a large number of people gather.

BACKGROUND OF THE INVENTION

As it is known, when using the services of establishments or public places in general, we usually find ourselves with the unpleasant situation that they encounter such dirt that makes their use practically impossible. Given this situation, the only possibility to try to maintain adequate hygiene in public toilets is through continuous cleaning, which represents an important economic cost and, even more, when traveling to the place where they are. Also, a major drawback is that the manual cleaning task, on many occasions, is a very unpleasant task given the existing dirt, as a result of the performance of unscrupulous people who do not take care of the facilities. In addition, the dirt that can accumulate in public toilets can lead to the spread of certain diseases such as aureginous pseudomonas, staphylococcus aureus, enterococcus hirae, escherichia coli, etc., all of them preventable with proper cleaning. Thus, as it is known in numerous public establishments, there are several toilets, mounted on a cantilever at a certain height or anchored to the ground, separated by a screen, which makes it necessary to invest a considerable amount of time in cleaning them. that makes cleaning management more expensive, which must be carried out continuously. In order to solve the inconveniences that manual cleaning of public toilets entails, we have tried to implement means that allow them to be cleaned automatically, so that the owner of this file, at the time, requested the documents ES 2 251 884 and ES 2 2531 1 1, so that in document ES 2 251 884 a "Automatic cleaning system for toilets" is described, consisting of a waterproof tent automatically foldable from a housing arranged in the wall adjacent to the toilet, in the floor or ceiling, and which completely covers the same, through which a system of pressurized fluid sprinklers directed towards the toilet is arranged, as well as an adequate drainage of evacuation of fluid and debris that it carries.

Document ES 2 253 1 1 1 describes improvements based on the tent being constituted by a cover based on a shutter of waterproof and corrosion-resistant slats, roll-up in a housing provided in the wall or floor, and guided by lateral guides provided in facing walls or side bulkheads flanking the toilet; on the ground there is a grid that covers all or a large part of the covered area, and under which the technical area is arranged as well as sprinklers directed towards the outside of the toilet.

Likewise, we can consider US patent documents 2,605,478; WO 95/30801; FR 2 74 743; US 5,655,233; US 4,348,776; GB 191228974 and WO 2006/048490, so that in US Patent 2,605,478 an apparatus for cleaning a bath is described, which is based on a rotating structure that incorporates cleaning means, said structure adapting a first position vertical leaving the toilet free and a second horizontal position on the toilet for cleaning. This structure makes all the elements accessible, which is a serious inconvenience. There is no cleaning of the exterior or of the floor and walls.

In WO 95/30801 a system is described which on the one hand has a rotating panel for closing a surface and a mobile armature carrying the spraying device.

Patent document FR 2 744 743 describes an assistance installation for automatic cleaning of a toilet, which is constituted by means that adapt a first retracted position on the wall and an extension position on the toilet, dragging in that position the liquid projection means. WO 2006/048490 describes a cleaning system defined by folding means on the toilet, whose folding means incorporate conduits for conducting liquid for pressure cleaning.

Finally, we can consider document ES2375031 of the same holder as the present file and in which a system based on a movable structure from a first folding position to a second position deployed on the toilet and between the side walls is described, the structure being of support equipped with a shaft driven by a motor reducer.

DESCRIPTION OF THE INVENTION

This report describes an automatic system for cleaning toilets, being primarily intended for automatic cleaning of toilets installed in public places, in large companies and public bodies, once they have been used being clean and disinfected prepared for a new use, so that the system comprises: a movable passenger compartment, with respect to a fixed structure, which in a first resting position is retracted, the toilet being accessible for normal use and in a second working position is displaced on the toilet to carry out a cleaning cycle;

a means of linear displacement of the cabin;

a water pump;

a soap / disinfectant pump;

a wax pump, and;

a control panel, so that the cabin with its side and upper sides closed presents: rotating blades for washing water supply arranged in its inner upper base;

at least one sprinkler to each inner side;

an air turbine, at its upper external base, associated with nozzles laterals that penetrate into the interior of the passenger compartment;

or a telescopic guide to each outer side, and;

or a window on its lower front face of the toilet passage. The linear displacement means of the passenger compartment are defined by a motor with a linear actuator and a set of plates, so that said displacement means can be replaced by any other equivalent means such as a rotary motor, a hydraulic cylinder, etc. Logically, the water, soap / disinfectant and wax pumps are communicated with the rotating blades arranged in the internal upper base of the cabin that insufflate the water and the precise products in each wash cycle on the toilet. That is, the system will incorporate the corresponding circuit for the contribution of soap / disinfectant, waxes or any other precise in the wash cycle.

Likewise, the water, soap / disinfectant and wax pumps are communicated with the internal side sprinklers of the cabin, allowing the toilet to be cleaned both by its internal surface and by its external surface. During the cleaning operation, with the passenger compartment in its second working position, the nozzles propel an air curtain over the window of the lower front face of the passenger compartment, acting as a closure.

After cleaning the toilet and moving the passenger compartment from its working position to its resting position, it causes the toilet to progressively dry.

To complement the description that is going to be carried out below, and in order to help a better understanding of the characteristics of the invention, this descriptive report is accompanied by a set of drawings, whose figures are illustrative and not limiting , the most characteristic details of the invention are represented.

DESCRIPTION OF A PREFERRED EMBODIMENT

In view of the aforementioned figures and according to the numbering adopted we can see how the automatic toilet cleaning system comprises a movable cabin 1 with respect to a fixed structure 2, which in a first rest position is retracted, being accessible The toilet 3 for normal use and in a second working position is displaced on the toilet 3 to carry out a cleaning cycle and be perfectly clean and disinfected. For this, the system incorporates a means of linear displacement of the passenger compartment 1 based on a motor 4 with linear actuator 5 and a set of plates 6, through which the passenger compartment 1 passes from its first resting position to its second position of Work and vice versa, being driven by telescopic side guides 7. Likewise, to carry out the cleaning cycle it incorporates a water pump 8, as well as a soap / disinfectant pump 9 and a wax pump 10, mounted on the fixed structure 2, associated with the corresponding hydraulic circuit.

In addition, the movable compartment 1 in its internal upper base incorporates rotating blades 1 1 and in its internal sides incorporates sprinklers 12, associated with the circuit hydraulic, through which it drives the water and cleaning products of the toilet 3, both for its internal surface and for its external surface.

Likewise, the movable compartment 1 in its upper external base incorporates an air turbine 13 associated with lateral nozzles 14 that penetrate inside the interior 1, so that during the cleaning process the lateral nozzles 14 propel an air curtain over the window 15 of the lower front part of the passenger compartment 1 closing it.

Thus, once the cleaning and disinfection cycle has finished, the passenger compartment 1, in its working position, will return to its resting position, so that in said path the nozzles 14 are causing the toilet 3 to dry, being prepared to A new use.

Likewise, the system incorporates a control panel 16 that will allow to program the cleaning cycle according to the needs and even it can be modified by Wi-Fi.

Referring to the figures of the designs, we can observe how in Figure 1 the passenger compartment 1, arranged in its second working position, will begin the cleaning / disinfection cycle, so that the rotation of the rotating blades 1 1 will drive the soapy water with disinfectant on the toilet 3 cleaning the internal part, and, simultaneously, by the side sprinklers 12 the soapy water with disinfectant is driven by the external surface of the toilet 3, making a total cleaning and disinfection of the toilet 3 and the surroundings.

In said figure 1 neither the soap / disinfectant pump 9 nor the wax pump 10 has been represented, nor the control panel 16 to be able to observe the linear displacement means of the passenger compartment 1 based on the motor 4 and the actuator linear 5 with the set of plates 6.

In addition, the activation of the air turbine 13 causes an air curtain to be produced by the side nozzles 14 that closes the lower front window 15 of the passenger compartment 1 by closing it during the cleaning and disinfection process.

Once the cleaning and disinfection has been completed, the movable passenger compartment 1 returns to its first resting position when the motor 4 is activated with a linear actuator 5 associated with the set of plates 6 that moves it, perfectly guided by the guides 7, to the time the air leaving the side nozzles 14 causes the toilet 3 to dry, leaving it clean and disinfected for a new use.

Thus, the activation of the motor 4 causes the linear actuator 5 to move in the direction of the arrow "A", while the passenger compartment 1 will move in the direction of the arrow "B" to its first rest position and to the Inverse when it comes to moving from its first resting position to its second working position.

Said motor 4 with linear actuator 5 may be replaced by any equivalent means such as a rotary motor or a cylinder.

Figure 2 of the figures shows how the lateral nozzles 14 remain, the cabin 1 being in its second working position, in the front part of the toilet closing the window 15 with an air curtain and returning to its first position At rest, after finishing the cleaning cycle, it will cause the toilet 3 to dry and leave it ready for a new use in a perfect state of cleaning and disinfection.

Likewise, in figure 3 of the designs it is observed how the lateral nozzles 14 remain on the sides of the toilet 3 and how by means of the lateral sprinklers 12 the external cleaning of the toilet 3 will be carried out and the spilled water will be expelled by the floor of the own cabin.

The structure reflected in the different figures can be part of a fixed structure or it can form a portable structure that can be used in those places that are temporarily necessary.
