Description

[0001] Multi-station sanitary container

[0002] The subject of the invention is a multi-station sanitary container, intended especially for use at mass events, as well as for individual rental and for the equipment of public institutions.

[0003] Vacuum sewage systems comprising two vacuum pumps and a controller are known from international patent application WO 2018132015 Al, wherein the pumps are configured to operate individually, in series, or in parallel, depending on the required vacuum demand. In addition, the device comprises an accumulator tank which functions both as a distributor for directing wastewater to the pumps and as a vacuum tank to ensure sufficient vacuum accumulation within the system. The device comprises an inlet pipe system connected to the tank and comprising at least one inlet connection intended to be connected to a field sewage system. The pump inlet is connected to the tank via a pipe system. The pump outlet is equipped with an outlet pipe system with an outlet connection, which can be connected to an external wastewater tank or a local sewage system. In the device, initially only one pump is activated to achieve the required vacuum level of approximately 50%. If additional capacity is needed due to increased flushing, the second pump is activated.

[0004] A vacuum system connected to toilets, urinals or sinks, containing a liquid ring vacuum pump with an integrated grinder is known from the description of the international invention WO 0190495 Al. The pump is connected via pipes to the toilets, and each toilet is fitted with a drainage valve. The pump starts and runs for a few seconds to establish a vacuum in the pipes between the toilet and the pump, and the drainage valve subsequently opens to empty the toilet, after which the valve closes and the pump stops shortly afterwards.

[0005] A multi-station vacuum toilet is known from Chinese patent application CN 107939082 A, comprising an elongated cuboid body with a vacuum station located at one end. A partition wall is arranged along the body, separating two rows of sanitary stations, each comprising a sanitary fixture such as a vacuum toilet bowl or a vacuum urinal. The vacuum discharge valves of the sanitary fixtures located at opposing stations are connected to a single pipe, the other end of which is connected to a vacuum pipe leading to the vacuum station.

[0006] In known solutions of multi-station sanitary containers, standard shipping containers are used as the structural base, which is advantageous in terms of transportability but imposes limitations regarding the arrangement of sanitary stations and the routing of the necessary installations. In such solutions, internal drains integrated into the container frame are often made of PVC pipes, which results in reduced tightness of the system. Additionally, in known solutions, certain components must be disassembled for transport, such as external air conditioning units or washbasins mounted to the outer walls of the container. Moreover, known sanitary containers require relatively precise leveling. Known solutions are often prone to pipe clogging and additionally require an external power source, which may be difficult to access. In summary, known solutions involve issues related to installation, transport, and ensuring long-term operation without the need for servicing or repairs.

[0007] A multi-station sanitary container comprising a cuboid body with two longer vertical walls parallel to each other, two shorter vertical walls parallel to each other and perpendicular to the longer walls, and further comprising two rows of sanitary cabins, each of which contains a toilet bowl, with one row of sanitary cabins located on one side of the longer walls of the container and the other row on the other side, and further comprising a technical duct in which the vacuum pipes of the vacuum sewage system are located, and a water installation connected to the toilet flushes, as well as a technical room in which the vacuum sewerage vacuum pump is located, and in addition, the container body contains an entrance to the technical room located on one of the outer walls of the container, characterized in that the technical duct is positioned between the rows of cabins and is separated from them by partitions, and the vacuum piping comprises main vacuum pipes, with each main vacuum pipe is connected to 2 to 4 vacuum discharge valves of the toilet bowls, each via a separate branch vacuum pipe, wherein the main vacuum pipes are arranged above the toilet bowls and their discharge valves, and furthermore, the main vacuum pipes are connected to a buffer tank, which is connected via a valve to the vacuum pump and the buffer tank is further connected via a valve to a vacuum separator located below it, which is also connected via a valve to the vacuum pump.

[0008] Preferably, the multi-station container comprises a power generator located inside the technical room, the power generator being connected to the floor of the technical room via linear guides, and positioned on the side of the entrance to the technical room, with the guides arranged perpendicular to said entrance.

[0009] Further advantages are achieved when the multi-station container comprises a central air conditioning system, wherein the indoor unit is located in the upper part of the technical room, and the outdoor unit is located in the lower part of the technical room, wherein each cabin is provided, in the upper part of its rear wall, with a supply air grille connected via an air conditioning duct to the indoor unit, and in the lower part of the cabin with an exhaust air grille.

[0010] Additional advantages are obtained when the multi-station container comprises two washbasins located inside the technical room, wherein one of the washbasins is positioned along one of the longer side walls of the container, and the other along the opposite longer side wall, each of the washbasins being accessible through an opening formed in the corresponding longer external wall of the container, and each washbasin is enclosed from the interior of the technical room by a body.

[0011] Further advantages are achieved when the multi-station container comprises a washbasin located inside the technical duct, on the side of the container opposite to that of the technical room, the washbasin being accessible through an opening formed in the shorter external wall of the container, and being enclosed from the interior of the technical duct by a body.

[0012] Further advantages are achieved when the vacuum separator comprises a drawer slidably arranged in its lower part, the drawer containing a separation sedimentation chamber.

[0013] The multi-station sanitary container according to the invention, by employing a vacuum sewage system, reduces water consumption — in the case of flushing, the water volume is reduced from approximately 5 liters to 0.5-0.7 liters — and does not require precise leveling. The arrangement of the main vacuum pipes above the discharge valves of the toilet bowls eliminates the problem of gravitational backflow of wastewater, facilitates the maintenance of stable vacuum within the system, reduces the risk of pipe clogging, and contributes to the reliable operation of the installation. The use of multiple main vacuum pipes, each connected to several branch pipes leading to the discharge valves of toilet bowls, enables a more balanced flow through each main pipe, eliminates the risk of overloading, reduces pressure losses, and additionally allows continued use of the toilets connected to the remaining pipes in the event of a failure of one of the main pipes. Furthermore, the sanitary container according to the invention does not include any components that need to be disassembled for transport. The washbasins do not protrude beyond the outer walls of the container. The arrangement of the generator on linear guides allows it to be slid into the interior of the technical room during transport. Both the outdoor and indoor units of the air conditioning system are located inside the technical room, which allows for maintaining temperatures within the comfort zone without causing difficulties related to the transport and on-site installation of the sanitary container. Additionally, the air conditioning system protects the internal technical space from freezing during winter. The use of a roll-up door at the entrance to the technical room reduces interference with designated circulation paths during maintenance of the sanitary container. The technical duct, located between the rear walls of the rows of sanitary stations, enables space-efficient organization of installation piping, allowing for optimal use of available space while ensuring easy access for system maintenance. Transport and installation of the container are simplified, while a number of solutions enhancing user comfort are provided, along with the integration of multiple sanitary stations within a single container. The solution according to the invention thus ensures a high level of user comfort, while also facilitating transport, enabling simple installation and maintenance, and reducing water consumption.
