This utility model is a mobile laundry, which is housed in a train carriage. Thus, its disadvantage is that the movement of the system is possible only with the help of railways. Installation of such a mobile laundry on a car is not possible due to its design features.

There is another model of a mobile laundry used by the military and produced by the Project-Technique Corporation: Mechanized field laundry MPP-9 is designed for washing, drying, ironing and uniforms of military personnel who are outside the permanent deployment in the field.

It includes the following modules: heat supply point (autonomous mini-boiler room); washing module; drying module; power plant on a trailer. Also, separate tents have a dirty linen module, a clean linen module, and a water storage module.

The mechanized field laundry MPP-9 is moved from place to place with the help of trucks (this requires four KAMAZ or URAL trucks) or railway transport (two or three railway platforms are required).

The mechanized field laundry MPP-9 is not a self-sufficient mobile system. Rather, it is a set of modules that each time you move it must be disassembled and assembled at a new location, which entails significant time costs for bringing the laundry into working order. In addition, the volume of the modules is such that several units of transport equipment are required to move all the modules. The fundamental difference between the claimed invention and the currently existing models of mobile laundries is the placement of the entire set of laundry equipment in one body or trailer with dimensions of about 6000 mm by 2400 mm. The complex can be installed both on a wheeled chassis with a wheel arrangement of 8x8 or 8x4, as well as on a separate trailer.

The technical problem, the solution of which is provided when using the claimed invention, is the lack of mobility of existing transportable laundry complexes.

Disclosure of the essence of the invention

The claimed invention is carried out in order to solve the above problem, and, therefore, the technical problem of the present invention is to develop such a mobile laundry system that would fit in the limited space of one body-van and provide a washing capacity of at least 50 kg of washed and dried laundry in hour. The technical result of the claimed invention is to enable the functioning of a mobile laundry, the dimensions of which do not exceed the dimensions of the body-van.

The essence of the claimed invention is as follows.

Mobile laundry located inside the van of a truck, characterized in that it includes a water tank fixed inside the van, one or two washing machines located parallel to the front wall of the van, one or two dryers located above the wheel arches of the van along the side walls of the van and an ironing roller located along the side of the van behind one of the van's wheel arches. The laundry is housed in the confined space of a box body or truck trailer, making it easy to transport the mobile laundry to places where there are no fixed laundry facilities. The invention can be carried out as follows.

To accommodate the system, it is proposed to use a box body with dimensions of 6094 mm by 2550 mm (external overall), 6000 mm by 2000 mm (internal) of the K6350 type, a wheeled chassis based on KAMAZ-6350, URAL-532362 with a wheel arrangement of 8x8 or 8x4 or a two-axle trailer ...

A stainless steel water tank with built-in heating elements is used to heat the water to the temperature required for washing. For heating water, it is proposed to use heating elements with a capacity of at least 20 kW. The water tank is installed close to the front wall of the van, in its inner space. Using a separate tank for heating water allows you not to waste time heating water in the washing machine itself, but to heat it up while rinsing. This speeds up the washing cycle, increases the maintainability of the complex, as it allows the use of tubular electric heaters of the washing machines themselves in a more gentle mode.

The optimum distance from the front wall of the box body to the beginning of the wheel arch is 2,130 mm. At a distance of about 1030 mm from the front wall of the standard KUNG van, a transverse reinforcing element of the KUNG frame is placed. It is not recommended to violate the integrity of this element, therefore, the door for feeding / loading dirty linen into the van, as well as the operator's entrance, is proposed to be placed only in the part of the side wall, between the front wall of the van from the side of the cab and the transverse reinforcing element of the van body. That is, to accommodate the door on the side wall of the box body, an area approximately 1030 mm long from the front inner wall of the box body is available, which makes it possible to obtain a sufficient distance from the water tank to the washing machine to provide the operator's working area. This space, in general, is sufficient for comfortable work, since the average radius along the outstretched arm of the operator is 770mm. According to GOST R ISO 3411-99, the minimum recommended length of the working space is about 1000 mm.

Directly washing is carried out by two washing machines of the passage (barrier) type.

Washing machines are located across the body of the K6350 type van, at a distance of about 1100 mm from the front wall of the van, which makes it possible to install a door in the wall of the van to the front reinforcing spar. Dirty laundry is loaded through this door. This arrangement allows you to divide the washing area into clean and dirty. By framing washing machines with cladding panels up to the ceiling of the van, complete separation of work areas is achieved.

The used washing machines have a shock-absorbing suspension of the external drum using springs and shock absorbers, computer control of the process of filling, washing, rinsing, spinning, draining, two doors of the external drum for loading and unloading laundry, opening upwards, held in the upper position by gas springs with installed locks blockers.

The sprung suspension of the outer drum allows you to increase the spin speed without destructive consequences for the box body, up to 700-1100 rpm. A high spin speed is limited by the strength parameters of the washing machine, a smaller one - by the increased residual moisture of the laundry (the achieved residual moisture of the laundry is about 50-60%).

Residual moisture 60-70% increases the drying time in the dryer. The value of the residual moisture content of the laundry after drying of about 6-12% can be achieved in this case for a much longer time or due to increased energy consumption.

The inner drum of the washing machine should have a volume of 100-300 liters if two washing machines are used, and 400-600 liters if one washing machine is used, made of stainless perforated steel, with two flaps that open up / down, locked with horizontal pins of the latches through the fold of the sash into the side wall of the inner drum directly or through bushings. To lock the pins themselves, there is a rotary handle with its own locking mechanism, which prevents spontaneous opening of the doors during the rotation of the drum.

Also, the washing machine has two drive motors, left and right, for rotating the inner drum through the semi-shafts rotating in bearing supports located on the side walls of the outer drum, a frequency converter for controlling the motors. The machines have valves for filling cold and hot water, a valve for draining water from a drum, a water level meter in a drum, a vibration sensor, a door closing sensor, an opening / closing sensor for filling valves. A washing machine with one motor can also be an option. Upward opening loading doors of washing machines allow you to save working space for the operator to move. If the loading hatches were opened sideways, then when opening the hatch of one machine, it would be difficult to access the other.

Washing machines are attached through holes in the bottom of the van to a U-shaped metal fastening frame fixed under the bottom of the van. This is necessary in order to reduce the load on the floor of the van, both when the van is moving and when the laundry is running, as the washing machines in operation generate increased vibration.

Soundproofing the laundry room can be done by attaching the cladding panels to the outside or inside of the van walls. Panels made of gypsum-fiber boards or other sound-insulating materials can be used as cladding noise-insulating panels. It is also proposed to install soundproofing panels on the walls of washing machines or soundproofing pads on the cladding panels to reduce the noise level inside the van.

The mobile laundry also includes two tumble dryers with an inner drum made of perforated stainless steel.

Dryers are installed inside the van above the van wheel arches and can be bolted over the wheel arches. In this case, the maximum length of the drying machine is limited by the length of the wheel arch and the diameter of the door of the loading door of the drying machine due to the need to provide free space sufficient to open the door of the drying machine.

From the side of loading things, the drum of the dryer can be held from below and from above by rollers, and the rear part is held by a bearing mounted on the half-shaft of the drum cross and driven by a belt drive from the engine. Alternatively, instead of supporting rollers, two bearings can be installed in the rear support. Also, the dryer has a fan for supplying drying air and at least one heating unit. One heating unit is used to operate a mobile laundry under normal external conditions with a capacity determined by the total load power of the entire laundry not exceeding 100 kW. The second heating unit can be used for operation at low temperatures with shutdown of heating of heater tanks, heating system, etc. and the transfer of all the released power to heating the air for drying.

Heating stages are switched manually by the operator at an outside air temperature of up to - 50 degrees Celsius. The control of the drying machine is computer-based, with the ability to adjust the time, drying temperature, speed and drum rotation time.

The dryer has at least one air temperature sensor downstream of the tubular electric heaters and at the outlet of the drum. Air in the dryer is supplied and discharged by means of air ducts, which are then discharged to the outside of the box body. Also, the dryer has an air purification filter, an autonomous fire extinguishing system, a special door lock in the open position, so that when the chassis is not horizontal on the ground, the dryer door is fixed and does not close spontaneously.

Dryers are located along the sidewalls of the van, above the wheel arches. For mobile laundry it is suggested to use tumble dryers with elongated inner drums. Typically, manufacturers increase the drum diameter to increase the performance of dryers. However, due to the limited space of the van, it is necessary not to increase the diameter, but to lengthen the drum while maintaining the diameter. The specific dimensions of the drum depend on the size of the van in which the mobile laundry is installed.

The location of the dryers above the wheel arches allows for a passage of approximately 700-750mm between the dryers and the washing machines. The weight distribution of the mobile laundry equipment is designed in such a way as to ensure the safe operation of the vehicle chassis, to reduce the risk of breakdowns when driving over rough terrain due to the balance of the equipment mass relative to the longitudinal axis of the van body.

The loading hatches of the drying machines are directed towards the unloading hatches of the washing machines, which makes it possible to reduce the distance of transfer of linen from the washing machine to the dryer. Dryers of a mobile laundry with elongated inner drums are made with beveled upper edges of the bodies, which allows them to be installed above the wheel arches close to the ceiling of the van and maximize the internal volume of the van to ensure the required performance for washing and drying clothes with a residual moisture of about 6-12% and not less than 50 kg / hour of washed, dried clothes.

The van can also be equipped with an ironing roller with an ironing zone width of 1000 mm. The ironing rink is proposed to be located in the back of the van behind the wheel arch, along the wall.

Electrical control panels are located on the opposite wall of the van, and there is also free space for placing auxiliary equipment, for example, the table and chair of the operator's workplace, or an iron with a board for ironing small items

All parts of the machines in contact with linen are proposed to be made of corrosion-resistant stainless steel; stainless fasteners can be used to fasten the main elements. This is necessary because high humidity in such a small volume when using other steel can lead to premature corrosion and difficulties in maintenance.

A real mobile laundry can be implemented on the basis of a standard KUNG with the following dimensions of the internal space: width - 2400 mm, length - 6000 mm. In this case, the width of the water tank is 300 mm. The distance from the tank to the washing machines is 800 mm. The distance between washing machines and dryers is 1000 mm, the length of the drying machine is 1150 mm, the distance between them is 700 mm. The width of the doors through which the linen is loaded is about 1000 mm, the width of the doors through which clean linen is dispensed is 1540 mm.

To operate the claimed mobile laundry, an electric generator with a capacity of at least 100 kW is required. It is located outside the van body and runs on diesel fuel. The equipment is powered using one or two cables. In this case, one of them is power, and the second is connected to an electrical panel, with the help of which control is carried out. It is impractical to use a generator of a different power: lower power will be insufficient for solving problems, higher power will entail problems with the installation of a mobile electric generator and increased fuel consumption.

Mobile laundry, implemented according to the above example, works as follows.

Water for washing is supplied through a fitting or tap installed in the floor of the van body, to which a rubber hose is connected from the outside. Inside the body, the incoming water is separated and, with the help of at least two hoses, the water tank and washing machines are filled at the same time. The operation of the equipment begins with filling the water tank, turning on its heating. At the same time, the mobile laundry operator loads the dirty laundry into the washing machine (s). Since the washing machines are equipped with their own heating elements, the washing process starts before the required temperature of the water in the water tank is reached.

When the required temperature in the water tank is reached, heated water from the tank is poured into the washing machine. The tank is replenished with a new portion of water and it is heated for the second wash. At this time, the washing machine washes, maintaining the water temperature with its own tubular electric heaters, drains out dirty water, fills in cold water for rinsing, rinsing, draining and wringing out the laundry. The water used in the wash is drained out through the drainage hole in the floor of the van, and moves along the hose connected to the hole to the desired distance for draining. At the end of spinning, the operator opens the unloading door and loads the clothes into the dryer, in which the clothes are dried. Simultaneously with the drying of the first batch of laundry, the washing machine performs the next wash. Dried laundry from the tumble dryer is either fed onto the ironer or removed from the machine. The dryer can have two heating stages depending on the ambient temperature, the desired mode is selected manually by the operator.
