Description

This invention is a mobile shower set that can be mounted on a truck.

Roadside car parks often have sanitary areas where sanitary buildings are available. As these buildings are used by a large number of people, the question of whether they provide sufficient sanitary safety is frequently raised. On the other hand, when driving in places where sanitary facilities are not available, bathing is not an option. There are millions of people in the world who work as professional drivers but do not have access to basic sanitary care such as showering. Fixed showers are only available in a small number of car parks, and as such car parks regularly accommodate more than 100 drivers, there is plenty of room for improvement in the sanitary conditions of the showers.

A simple solution is known as a mobile shower. In most cases it is a small cabin on a self-folding lightweight frame, similar to a small tourist tent. A lightweight cover with a zippered entrance opening is attached to the frame. The installed shower room has no floor. Bathing is done by pouring water from a container placed inside, or, in more luxurious versions, by sending it to the end of a hose by a pump. In both cases, the problem of used water arises. If the cabin does not have a floor, used water and cleaning agents leak out and contaminate the surroundings. If the cabin has a floor, the problem is even greater, as the water has to be removed from inside the cabin, which also contaminates the surroundings. This type of cabin is easy to disassemble and assemble and takes up almost no space, but it does not allow washing with hot water and there is no option to dispose of used water in an environmentally friendly way. Such existing showers are not possible in the cabin of a truck, even if you want to use them.

China Utility Model Patent CN211796086U

A portable mobile shower is known from Patent Document 1, and includes a folding tent, a shower head, a hot and cold water mixer, a water pump assembly, an electric control box, a water purification bucket, a drainage bucket, a tent support, a ceiling, a side enclosure, a drainage tank, a seepage plate, a water pump mounting base, a first water pump, a second water pump, and a third water pump. The folding tent is composed of a tent support, a ceiling, a side enclosure, a drainage tank, and a seepage plate. The roof slides to the outside of the upper part of the tent support, and the side enclosure slides to the outside of the lower part of the tent support. The side enclosure is connected to the ceiling by a zipper, and the drainage tank is located at the bottom of the tent frame, inside the side casing. The seepage plate is attached and installed on top of the drainage tank. The shower is hung and installed on the top of the tent pole. Three water pumps are permanently installed on the mounting base, and an electric control box is permanently installed on the mounting base of the first water pump via the pole. The water inlet of the first water pump is connected to the bucket via a water pipe. The first end of the water outlet is connected to the hot and cold water mixer via a water pipe. The water outlet of the hot and cold water mixer is connected to the shower via a water pipe. The water supply pipe is connected to the drain tank, and the water outlet of the third water pump is connected to the drain bucket via a water supply pipe.

The structure as seen from the description in the patent is complex and consists of many parts. Although of high quality, disassembly and assembly are complicated. In addition, the large number of parts increases the volume and weight of the entire set, which is not suitable for people who want to use such a shower in the cab of a truck, which has a floor space of only about 4 ^m2 . Moreover, for people who make long journeys or who change their place of stay or residence frequently or daily, it takes too much time to unfold and assemble such a structure. In addition, the large number of parts that require assembly and disassembly makes it almost impossible to use such a shower in the cab of a truck.

It is necessary to develop a design that meets user expectations, is easy to assemble and disassemble, takes up little space when folded, is comfortable and easy to maintain, and is eco-friendly in the natural environment.

Polish patent application P. 441979 is known as a portable shower. It has a closed water circuit consisting of a cold water tank connected to a hot water tank via a pump and a thermostatic mixer tap in the shower. It is characterized in that it has a shower base with a heated water reservoir connected by a tap attached to the shower base and the cold water tank, an internal coil connecting the circuit with the thermostatic tap of the shower, an outlet connected by a pump and a filter system to the heated water reservoir and from the bottom of the shower base to an isolation pad, the heated water reservoir containing a heating system in the form of an electric heater.

The invention is a portable shower set with walls and a ceiling, a water tank, and a rubber hose with a shower head. The shower set can be installed inside a truck, and inside it has a curtain made of a waterproof material that can be fixed to a shower base, and the top can be attached to the ceiling of the truck cab.

The second version is a cabin with a chamber filled with compressed air and a curtain that, once filled, becomes a cabin ready for showering. The shower base can be fixed and the top of the base can be attached to the roof of the truck cab. Heated purified water is supplied to the curtain via a hose by a water pump. The water in the purified water tank is heated by a heater with a thermostat. The hose leads to a shower head with a water pump switch. The shower base has a spout that drains the waste water into a waste water tank. The heater and the water pump are powered by an electric cable at a voltage of 12 VDC or 24 VDC depending on the vehicle. The shower base can be installed in one of the two side compartments of the truck cab. The purified water tank can be installed under the bed of the truck cab or outside the rear wall of the cab. The waste water tank can be installed outside the truck cab, under the floor.

This solution allows drivers to shower without having to leave the cab.

The mobile shower set of this invention can be mounted on a truck as an add-on, and all that is required is to convert both beds into foldable ones and install water inlets and outlets inside and outside the truck.

The shower comprises a folding curtain 10 made of waterproof material which forms the entirety of the four walls and ceiling, a rubber hose with a shower bed 11, and a shower base 19 with a safety door 5. In use, the curtain 10 is fixed to the wall of the shower base 19, fastened to a hook 17, and hung from a ring in the ceiling of the truck, or temporarily attached to the ceiling of the truck in another similar manner. One side of the curtain wall has a zipper 16 which can be opened to allow access to the shower room.

The frame of the curtain 10 may consist of four interconnected air chambers 9 filled with compressed air via air valves 14. The shower structure comprises a clean water tank 12 and a drain tank 13. The clean water tank 12 contains a water pump 3, to which a hose is connected, leading to a shower head 11 with a switch 15 for the water pump 3, and a heater 1 with a thermostat 2, via which the desired temperature can be adjusted. The heater 1 and the water pump 3 are supplied with power from the truck vehicle equipment via an electrical cable 20, at a voltage of 12 VDC or 24 VDC depending on the vehicle. To pour the clean water, a hose with a screw cap 6 is used.

The drain tank 13 has a spout 7 with a screw cap. Wastewater from the shower base 19 flows into the drain tank 13 via the drain outlet 4 and the drain pipe 8. The tank 13 is canister-shaped, and after using the shower, the tank can be removed and carried to a place with a sewage system, and the wastewater can be drained from the outlet. This model of mobile shower for trucks includes a curtain 10, a shower base 19, a water purification tank 12, a drain tank 13, and a hose with a shower head 11.

When the curtain 10 is unfolded, its four walls are fixed to the ceiling of the vehicle, and its lower part is fixed to the wall of the shower base in the side compartment of the cabin. When using the shower, the curtain 10 is attached to the ceiling of the truck cab with the hooks 17 at the top and casters. The shower can be accessed by folding down about one-third of the lower and upper beds inside the truck. A purified water tank 12 and a drain tank 13 are installed under the bed or outside the cab of the truck. A water pump 3 is installed in the purified water tank 12, and a hose with a shower head attached to the end with a switch for the water pump 3 is connected to the water pump 3.

The clean water tank is equipped with a fill tap. The waste water tank is equipped with a drain plug. The walls and ceiling, i.e. the shower curtain, are made of waterproof material and are secured to the ceiling of the truck using assembly techniques such as hooks, rings, Velcro, zippers, buckles, snaps, etc. The frame that secures the curtain may consist of an air chamber 9 filled with compressed air, in which case the frame is provided with at least one lockable access/door. The shower walls and ceiling are made of waterproof material and are secured to the frame. The air chamber frame is provided with four access doors to allow for quicker emptying of the air chamber 9.

The purified water tank 12 is fitted with a heater 1 with a thermostat 2, which heats the water to a desired temperature and allows the water to be adjusted to the desired bathing temperature using the thermostat 2. The heater 1 and water pump 3 are powered via an electrical cable 20 at a voltage of 12 VDC or 24 VDC depending on the vehicle. The heater output is adjusted to match the output of the power supply. The shower is folded up and placed in a side storage compartment on the left or right side of the truck cab. The user tops up the purified water tank 12 with the water he needs.

Next, to heat the water in the purified water tank 12, the heater 1 is switched on and the desired temperature is set with the knob of the thermostat 2. When the water is heated and reaches the set temperature, this state is signaled by an indicator light or an acoustic signal. Next, the two beds are folded up by about 1/3 to allow access to the side luggage compartment from inside the cab. The next step is to lift the door that protects the curtain 10 from mechanical damage caused by luggage carried there and install the curtain 10 together with the shower head 11. The curtain 10 is fixed using the hooks 17 at the top of the curtain 10 and the casters fixed to the roof of the truck, and the curtain material is stretched to the top. One of the walls of the curtain 10 has a zipper 16 that can be opened to access the shower room.

When the user enters the shower room, the water pump 3 next to the shower head 11 is activated. The water pump 3 starts to pump up hot water. Hot water starts to come out of the shower head 11 at the temperature set by the thermostat. A drain 4 is installed at the bottom of the shower, and the wastewater flowing through the floor of the shower base is drained into the drain tank 13 by gravity. After the shower is finished, the user leaves it to dry. Next, the curtain 10 is removed from the roof of the truck cab, the curtain 10 is folded into the shower base 19, and the door of the shower base 19 is closed. The canister-shaped drain tank 13 is unhooked from the dirty water drain pipe 8, carried to a location where the sewer is located, and the contents are discharged into the sewer. If the frame has the form of an inflatable air chamber 9, the air can be released by loosening the inlet and outlet valves in a similar procedure. The walls and ceiling material of the curtain 10 are folded into the shower tray 19, and the protective door of the shower base 19 is closed.
