Description

The utility model relates to devices for cleaning the interiors of vehicles, in particular to built-in vacuum cleaners, and can be used for cleaning and cleaning rooms for passengers on vehicles. It is most suitable for cleaning cabins on ships or compartments in passenger rail cars.

It is already known to use a vacuum cleaner to clean the compartment and corridor of a passenger carriage, which is usually carried out at the points of formation upon arrival of trains and at points of turnover. For this, a household electric vacuum cleaner is used, which is included in the compartment opposite the second and eighth compartments located in the corridor of the car, as well as in the outlet compartment itself [1].

Cleaning passenger rooms with a known vacuum cleaner requires moving it around the car, it takes a lot of time and time-consuming. During the operation of non-stationary (moving during the cleaning process) vacuum cleaners, filtered air, as a rule, is discharged into the space of the cleaned room and contains a certain fraction of dust not retained by the filters and subjected to electrification when passing through the internal channels of the vacuum cleaner.

In addition, the filtered air emerging from the vacuum cleaner creates air flows in relatively small rooms (compartments, corridors), entrain the dust, which is suspended for a long time, and then settles, reducing the quality of the cleaning.

The closest analogue of the claimed utility model is the technical solution described in [2] and related to the built-in vacuum cleaner of the vehicle (car).

The known vacuum cleaner contains a chamber associated with a means of creating a vacuum in it, filter elements connected to the chamber of the inlet air pipe, at the outlet of the cabin of which there is a pneumatic connector for connecting a flexible hose with replaceable nozzles installed at its end and a filtered air outlet pipe connected to the camera.

The known vacuum cleaner allows to reduce labor costs and reduce the time for cleaning the passenger compartment of the vehicle, since it does not involve moving the discharge chamber with filtering elements during the cleaning process, however, when used on vehicles with a large number (or area) of passenger spaces (compartment of a passenger carriage or cabin) It requires laying an extended air pipe, which leads to an increase in the mass of the vehicle, the complexity of its design and to an increase in the cost of manufacturing Nia.

In addition, the effectiveness of the known vacuum cleaner is not very high due to the low degree of vacuum in its chamber, since the source of vacuum in it is the air supply system to the internal combustion engine.

The objective the utility model aims to solve is to reduce the cost of manufacturing a vehicle and increase the efficiency and quality of cleaning passenger rooms, and the technical result that can be achieved by using it is to simplify the design and reduce the mass of the built-in vacuum cleaner.

To solve this problem and achieve the specified technical result in a vacuum cleaner for cleaning the vehicle interior, containing a chamber with means for creating a vacuum in it, filter elements, an inlet air pipe connected to the chamber, with which a flexible hose is attached with nozzles installed on its end and communicating with the air outlet pipe, it is proposed that the air pipe be made in the form of hollow handrails and rails laid along the premises for passengers (cabins, compartments), on which to install air orazemy for docking the flexible hose, that is, In a utility model, it is proposed to combine the functions of the railing in the corridors of passenger compartments and cabins with the air pipes of the dust extraction system.

Each pneumatic connector on the air pipe can be equipped with a pneumatic valve and / or plug, and a rigid pipe can be installed between the flexible hose and nozzle -

extension cord with a handle and remote controls for creating a vacuum.

The filter elements can be located as in the prototype - in the chamber in front of the means of creating a vacuum in it, or in a removable unit installed between the flexible hose and the rigid extension tube.

In this case, the means for creating a vacuum can be made in the form of an electric fan installed in the chamber, or in the form of an ejector communicating with a source of compressed gas.

To increase the degree of dust cleaning of the premises, the air exhaust pipe can be taken outside the vehicle interior.

A possible constructive implementation of the utility model for installation on passenger cars is illustrated in the accompanying drawings.

Figure 1 shows a fragment of a passenger car with a built-in vacuum cleaner located on its side wall along the corridor.

Figure 2 presents a diagram of a passenger car, top view.

Figure 3 is a view And from the compartment to the side wall of the car.

The built-in vacuum cleaner of the passenger car 1 can be placed on its side wall 2 along the corridor 3 and contains a chamber 4 with a means for creating it

discharge 5 (figure 3), filter elements 6 and connected to the chamber 4 inlet air pipe 7 and the outlet pipe 8, the outlet of which is located outside the passenger compartment 1.

The inlet air pipe 7 is made in the form of a carriage 1 fixed to the side wall 2 of the car 1 and a hollow handrail passing along its corridor 3, which ensures the convenience and safety of passengers moving in the process of vehicle movement.

On the inlet air pipe 7 there are pneumatic connectors 9 for joining the flexible hose 10. Each pneumatic connector 9 can be equipped with a pneumatic valve 11, as well as a plug 12 (figure 3).

For the convenience of using a vacuum cleaner, a rigid extension tube 13 with a handle 14 and a control member 15 of the vacuum generating means 5 can be attached to the end of the flexible hose 10. The control 15 can also be wireless, providing on-off means for creating the vacuum 5, which, in its in turn, it can be made in the form of a fan 16 installed in the chamber 4 (Fig. 3) with an electric drive or in the form of an ejector communicating with the source of compressed gas and with the cavity of the chamber 4 (not shown in the drawings).

The filtering elements 6 can be located in the chamber 4 in front of the means of creating a vacuum in it 5 or in a removable block 17 (Fig. 3), installed between the flexible hose 10 and the rigid extension tube 13, at the end of which replaceable nozzles 18 are attached.

If it is necessary to clean the rooms of the car 1, one flexible hose 10 is connected to one of the pneumatic connectors 9 on the inlet air pipe 7. For this, the plug 12 is removed and the flexible hose 10 is joined with the pneumatic connector 9, automatically opening the pneumatic valve 11.

Then, with the help of the control element 15, the means for creating a vacuum 5 in the chamber 4 is turned on, dust and small debris together with air are sucked in through the nozzles 18 into the chamber 4, passing through the filtering elements 6, and the cleaned air leaves the outlet 8 from the passenger compartment of car 1.

After cleaning the room near the first pneumatic connector 9, the means for creating a vacuum 5 is turned off, the flexible hose 10 is undocked, while the pneumatic valve 11 is automatically closed and the flexible hose 10 is attached to the next pneumatic connector 9.

The filtering elements 6 are periodically cleaned by removing them from the chamber 4 or replacing the removable unit 17.

Declared as a utility model, the built-in vacuum cleaner provides quick and convenient cleaning of the vehicle premises, which does not require large labor costs, while the vehicle is not complicated, and its mass practically does not increase.
