Field of the Invention The present invention generally appertains to improvements in cleaning systems and especially relates to new and novel improvements in a system for automatically cleaning enclosed areas and articles contained therein, most particularly public rest rooms and the wash and toilet facilities disposed therein.
2. Description of the Prior Art The presence of unsightly and unsanitary public rest rooms, especially in gasoline service stations, is so well known and the existence of which has become so general, as of late, that no considerable elaboration need by given to the problem to which no solution has become apparent. In the latter regard, the only solution is the ancient one of employing efficient manual labor on an inspection schedule to clean the rooms and the facilities therein. Unfortunately, present economic and sociological conditions all but negate the employment of competent and reliable workmen to maintain such public rooms in sanitary and attractive condition.
Attempts to eliminate the need for utilizing manual labor in effecting cleaning operations of such rooms by providing automatic cleaning systems have not been fruitful. One such cleaning system is disclosed in U.S. Pat. No. 3,381,312, wherein cleaning implements are stored in the ceiling of a bathroom above the toilet facilities and are automatically lowered relative to the facilities and then rendered operative to distribute washing and rinsing fluids to the facilities and then returned to their storage places while suction hoses function to remove any water accumulation on the floor around the facilities and a heater and fan operate to circulate drying air through the bathroom.
Such bathroom cleaning system may function fine in public buildings having large bathrooms housing a considerable number of toilet facilities and where it is only desired or necessary, due to ample manual labor, just to clean the toilet facilities in an automatic manner with manual labor being able to clean the remainder of the bathroom. Even so, such system for primarily cleaning the toilet facilities is only a partial answer to the problem. And such partial solution would be to no avail because the cost of installation and operation thereof, due to its complex nature, would be so high as to economically preclude its installation and use in public rest rooms in service stations, small restaurants and the like privately owned establishments dedicated to serving the public.
SUMMARY OF THE INVENTION The present invention is summarized in that a cleaning system for cleaning the interior of a room enclosure equipped with toilet facilities without the employment of manual labor includes a pipe network arranged over portions of the inner wall structure of the enclosure, nozzle units carried by the pipe network within the interior of the enclosure, to unit fluids onto all parts of the enclosure, and input means connected to the pipe network for sequentially conveying cleaning fluids to the pipe network for emission therefrom by the nozzle units.
The purpose of the present invention is to ensure that public rest rooms or any bathroom facility, for that matter, are maintained in clean, sanitary and aesthetically appealing condition without necessitating the expenditure of manual labor to accomplish this directly.
Accordingly, an object of the present invention is to construct an automatically functioning, dependable, reliable and economically practical and efficient system for washing, rinsing, sanitizing and drying the entire and overall inner surface of a rest room and with particular emphasis on the wash and toilet facilities therein.
The present invention has a further object in that a self-contained room structure may be permanently installed as a functioning unit in a building and which is equipped with built-in plumbing fixtures, such as wash bowl, toilet and urinal, and which has a built-in integer of an automatically operating spray nozzle and piping arrangement for directing in a strategic and sequential manner over the wall and floor surfaces and into and over the plumbing fixtures effective sprays of wash, rinse, sanitizing and drying fluids from appropriate supply sources provided as operating adjuncts to the maintenance and consequent proper operation of the rest room unit.
BRIEF DESCRIPTION OF THE DRAWING The accompanying drawing contains a perspective view, partly broken away and shown in section, of a room structure that exemplarily typifies a selfcontained rest room in accordance with the teachings of the present invention, especially with regard to the automatic cleaning system which is shown structurally in perspective and also shown mainly diagrammatically.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now more particularly to the accompanying drawing, the numeral 10 generally designates a room enclosure which is a self-contained structure constructed and adapted to be permanently installed in a building so as to function therein as a public rest room or, at least, as a bathroom, for example if installed in a dwelling not given to serving the public.
The room enclosure 10 is molded or formed from fiber glass which has an inner hardgel surface. The enclosure is composed of walls 12, a ceiling and a floor 14, with the latter being pitched toward a drain area 16. One or more of the walls is provided with an ingress and egress door 18. The room enclosure is provided with built-in plumbing fixtures that are operatively oriented along one side wall 20 and include a wash bowl 22 and a commode 24. Also, a urinal 26 is preferably positioned along another side wall 28. Of course, such provision and placement of the facilities is merely exemplary and the room enclosure is shown in its simplest form devoid of any partition walls and any customary furnishings.
Built into the walls of the room enclosure, as by being molded therein in the instance of plastic piping or by being integrally associated with the exterior surface of the walls thereof, is a series of pipes 30. The pipes are laid out in a series pattern along the side walls and in adjacency to the ceiling with the pipes being adapted to convey commonly various fluids into the interior of the room enclosure. The particular design placement of the pipes is not of importance and some of the pipes can pass over the ceiling, if desired. It is important that a network of piping be established to ensure a minimum amount of pipe with a maximum amount of coverage in the distribution of fluids into the interior of the room enclosure.
In the latter regard, a number of rotating nozzle units 32 are provided with the nozzle units being rotatably attached to offset pipe ends 34 on the pipes and being of a nature so that fluid emitted from the nozzle imparts a rotational force to the nozzle heads attached to the pipe ends 34. The nozzle units are placed in a minimum strategic arrangement so that fluid sprays therefrom impinge on the entire inner wall and floor surface of the room enclosure 10. Thus, certain of the nozzle units, as partly shown, will be on opposite walls and will have their jets directed so as to spray up and down all over the opposing wall. The ceiling and floor will also be effectively sprayed.
The floor drain area 16 is formed with a drain outlet 38 that is in communication with a stand pipe 40 whereby fluids from the nozzles are carried off from the drain area after effectively flowing down the walls and over the floor.
Preferably, the nozzle units will sequentially emit a washing fluid, a rinsing fluid, a sanitizing fluid and then a drying fluid. Such sequence can be of an automatic timed nature or can be the result of manual operation of suitable controls for operating equipment which constitutes maintenance adjuncts in association with the room enclosure 10.
In this respect, water from a main water supply is carried by a main water supply pipe 42 to a motor driven pump 44, which in some instances-where the water supply pressure is high enough may be eliminated. Usually though the pump will be required to develop and maintain the necessary water pressure. The output line 46 of the pump communicates with a four-way valve 48 which can be manually operated or can be automatically controlled by a motor driven timer mechanism in consort with the operation of the pump.
In one position of the valve 48, the water output from the pump or, at least, from the supply pipe 42 in the absence of the pump, passes through a line 50 which carries a detergent reservoir 52 with the water, as it passes through the line 50, becoming admixed with detergent so that wash fluid is carried to the main input line 54 downstream from the valve and in direct communication with the piping 30.
In another position of the valve 48, clear water passes through the valve from the pump or directly from the water supply line 42 to the main input line 54 which operation constitutes the rinse cycle.
In another position of the valve 48, wherein the pump is out of operation or the line 46 is closed off, the input line 54 is in communication with the output line 56 of an air compressor 58. In such position, air is carried to the nozzle units 32 and 36. When the air line 56 is in operation, the passing air picks up a metered quantity of sanitizing fluid from the reservoir 60 connected by a metering and closeoff valve 62 to the air line 56. The reservoir 60 can be closed off so that only air is conveyed to the nozzle units 32 and 36.
While the air compressor is shown in communication with the valve and piping arrangement as the source of drying air currents, such can be replaced by a motor driven blower in communication with the room enclosure directly or through the piping and nozzle units. Also, if necessary, the air, in either instance, can be heated. However, this most probably would not be necessary because of the good drainage conditions.
While the room enclosure is shown and described as a self-sufficient expressly formed and fabricated unit, it can be appreciated that the cleaning system, as shown and described, can be installed for excellent operation in existing rest rooms, especially since the majority of such rooms have tiled walls and floor drains, with the latter being the only real important factor. And even then, if the room has adequate drainage through a door or the like, the absence of a floor drain will not be detrimental to the operation of the system.
Inasmuch as the present invention is subject to many variations, modifications and changes in detail, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
