Description

The invention relates to sanitary-hygienic means, in particular, to devices for cleaning the soles of shoes.

The prior art portable shoe care device for cleaning shoes, including a housing in which an electric drive, rotatable rollers and a cleaning element in the form of a tape closed in a ring are placed (patent RU 122007 U1, IPC A47L 23/00, publ. 20.11.2012.) . A disadvantage of the known device is its low productivity, which does not allow it to be used to clean the soles of shoes at the entry points of a large number of people.

The prior art also knows a device for cleaning the sole of a shoe, including a trough-like body with washing liquid, a composite drive drum made of sections mounted on an extended shaft and kinematically connected to it by friction clutches to limit the moment of transmission of rotation, a rotation drive, a driven drum, a plurality closed in the ring of cleaning tapes, dressed on drums and tape cleaning device, the force of pressing which to the cleaning tape is less than the force on the above friction clutch sections rivodnogo drum.

Each cleaning tape of the aforementioned device is a lamellar chain, the links of which are equipped with removable brushes. (Patent RU 2096017 C1, IPC A47L 23/22, publ. 20.11.1997.)

The disadvantages of the device are the increased complexity of the design of the tapes, uneven movement due to the fact that in chain transmissions with a constant speed of rotation of the driving drum, the chain speed is not constant, but depends on many factors, in particular, on the link structure, the shape of the surface of the drive drum, and so on. In addition, there is a risk of resonance phenomena and increased noise during operation. The disadvantages of this design can also be attributed to the high complexity of manufacturing and inconvenience of operation. It should also be noted that there are two extended shafts in the design, on one of which drive drums are installed, and on the other - driven drums. In this case, the tension of the cleaning tapes is carried out by applying force to the specified shafts, which leads to their deflection and uneven tension of the tapes.

A device for cleaning the sole of a shoe is also known, including a body with a trough-shaped recess for washing liquid, an upper grill covering the recess of the body, a rotation drive, cleaning elements in the form of wedge belts closed in a ring having in the upper part of the brush, two continuous drive shafts leading pulleys mounted on drive shafts, two driven shafts, driven pulleys that rotate freely on driven shafts, a cleaning device for brush belts and nozzles for supplying washing or disinfecting liquids. (German patent DE 4441637 C2, IPC A47L 23/26, publ. 05/30/1996.),

The disadvantages of this device are: increased complexity and low technological design, inconvenience of operation, due to the difficulty of replacing brush belts;

The increased complexity of the design is due to the presence of two drive shafts, two driven shafts, twice the number of brush belts with their counter rotation.

The presence in the design of two pairs of extended shafts (leading and driven) makes it impossible to ensure uniform tension of the belts due to the deflection of these shafts and, as a result, limiting the length of the cleaning surface of the device along the axes of the latter.

The inconvenience of operation is explained by the presence of continuous drive shafts on which the pulleys rotate, both driving, driving brush belts, and driven. To replace one failed brush belt, it is necessary to completely disassemble the entire design of the device, dismantle all shafts, brush belts and pulleys.

The prior art also known device "Mat disinfection", which is made in the form of a sealed container, the lower and side walls of which are made of chemically resistant waterproof material and are tightly interconnected, and the upper wall, which is connected with the side walls, is flexible waterproof. At the same time, a porous filler is placed between the upper and lower walls, which is impregnated with a disinfectant, the upper wall contains holes with a diameter of 0.1-0.5 mm and a diameter of 1-10 mm, which alternate with each other.

The device allows for cleaning and disinfection of the soles of shoes when passing through the mat without allocating special time to clean the shoes. Since the action of the mat appears only when heaviness in this particular case affects the surface - the weight of a person in shoes (Ukrainian patent No. 84506 MKI A47L 23/00)

The disadvantage of this device is that the device does not provide automatic removal of dirt after passing a person in shoes, dirt will accumulate in the middle of the container, which must be periodically cleaned or washed, refilled with a disinfectant and change the filler. The device is labor intensive to operate.

Also known is a vacuum cleaning mat for cleaning shoes, including a flat sealed container with filler, the upper wall of the container made with holes for the filler to interact with the sole of the shoe being cleaned, while the sealed container is placed in a rigid case and is made of two autonomous sections, the upper and lower separated by a membrane, the lower airtight section is filled with compressed air with a pressure above atmospheric, the upper airtight section is filled with air with a pressure below atmospheric, the filler in made in the form of valves, the valves being mounted on the membrane surface with the possibility of overlapping the openings of the upper wall of the sealed container, while the sealed container with a pressure below atmospheric is connected to a suction pipe located along the wall of the housing, while the pipe is provided with a side slot along its entire length and connected the free end with the main pipeline, the pipeline, in turn, is connected to the capacity of the vacuum cleaner to collect dirt. (patent RU 118533, IPC A47L 23/00, published on July 27, 2012)

The known device is intended for dry cleaning of the sole of shoes, which, although it is an advantage, in contrast to the known analogues, it is intended only for cleaning the sole of the shoe and does not disinfect it, which is especially important when entering children's and medical facilities.

The task was set: to develop an apparatus that provides environmentally friendly automatic dry ion cleaning and disinfection of the sole of shoes, not laborious in operation.

The technical result consists in the creation of an apparatus providing high quality automatic dry ion washing and disinfection of the sole of the shoe, not laborious in operation, using high-frequency ion processing as the main tool.

The apparatus for automatic dry ion cleaning and disinfection of the sole of a shoe comprises a housing made with a recess in the upper part surrounded by a sealing collar. In this recess are placed supporting rotary tubes. The tubes have longitudinal grooves for the output of high-frequency ion pulses. Inside the housing there are: a high-frequency ionizer, a distributor, a compressor, an aspiration unit and a garbage container. The controller controls the device, on the upper part of the case there is an indication monitor. The device is connected to a standard electrical network via cable.

The use of high-frequency ion bombardment in the design allows for environmentally friendly high-quality dry cleaning and disinfection of the sole of the shoe.

Unlike most other methods that selectively affect pollution, ion bombardment very effectively removes various contaminants. As a result, by means of ion sputtering, surfaces are cleaned of contaminants having any adhesion strength to the material. The advantage of this washing method is that the process itself is environmentally friendly. It does not use consumables, does not pollute the surface and does not cause damage to the surface layers of the material. Surface cleaning is carried out by high-frequency ion bombardment. Ions are introduced into the pollution, transfer the charge and destroy them by the forces of electrostatic repulsion of the same charged particles.

An analysis of the known technical solutions carried out according to scientific, technical and patent documentation showed that the set of essential features of the claimed technical solution is not known from the prior art, therefore, it meets the condition of patentability of the invention “novelty” and “inventive step”.

The design description is illustrated by graphic materials, which depict the following:

Figure 1 - shows a General view of the apparatus for automatic dry ion cleaning and disinfection of the sole of the shoe.

Figure 2 - shows a section along the longitudinal axis of the apparatus.

The apparatus includes: a housing 1, made with a recess in the upper part with a sealing collar 2, support tubes 3, made with longitudinal grooves and installed with the possibility of rotation around its axis. Inside the housing there are: a high-frequency ionizer 4, a distributor 5, a compressor 6, an aspiration unit 7, a garbage collection container 8, a power supply unit 9, a controller 10, an indication monitor 11 is located in the upper part of the housing 1. The device is connected to a standard electrical network via cable 12.

The process of automatic dry ion cleaning and disinfection is as follows:

The visitor sets the foot in the shoe into the recess of the apparatus on the support tubes. The sensor detects the presence of shoes on the support tubes and turns on the suction system while filling the sealing cuff with air. Then, air passing through a high-frequency ionizer is saturated with active ions and is fed into the working grooves of the support tubes. The distributor controls the process of supplying ionized air to the tubes. The tubes rotate along their axes, making synchronous-vibrational movements. Penetrating into the pollution, the ions crush the adhering lumps of dirt, grease, moisture, etc., which are sucked off by an aspiration system into a garbage container. At the same time, the ion flow disinfects the sole of the shoe. The process lasts for a predetermined time, after which the supply of ionized air is turned off, followed by suction, then the sealing cuff is blown off and the visitor takes his foot off with cleaned and disinfected shoes.

 The process is controlled by an integrated controller, with an indication of the parameters. When the garbage container is full, the device generates a notification about the container cleaning. The device is connected to a standard power supply network.

The present invention can be implemented on standard equipment using modern materials and technologies.
