Description

The invention relates to a device for cleaning and disinfecting objects according to the preamble of the 1st protection claim and is used in particular for cleaning and disinfecting objects containing textiles such as clothing, shoes, sports equipment, backpacks or helmets and the like, and thus especially objects or items of clothing that are preferably worn on the body as well as blankets, mattresses, carpets and also stuffed animals or textile upholstery in or out of vehicles

Such objects or textiles are preferably to be cleaned by means of a washing machine and subsequent drying in a tumble dryer, whereby dirt, germs, bacteria and fungi are removed. In nature, bacteria and fungi feed on the sweat and dead skin particles given off by humans. A gas is excreted as a digestive product, which can be perceived as an unpleasant odor. However, not all products that come into contact with sweat or other odorous substances (smoke or food) can be cleaned in the washing machine, or the material suffers from too many washes. For example, shoes, especially sports shoes, gloves (especially if they contain leather), crash helmets and the like, should not or cannot be washed completely in a washing machine or even completely by hand.

Irradiation with ultraviolet light can kill bacteria in liquids and substances and many organisms can be inactivated or destroyed. This can be viewed as disinfecting the irradiated area. These microscopic organisms include, for example, spore-forming and non-spore-forming life forms or viruses or bacteriophages or cysts.

From the pamphlet DE 698 01 450 T2 a method for disinfecting liquids and gases and devices for using said method are known. The document relates in particular to methods for disinfecting liquids and gases by means of light which is radiated into the liquids and gases through light guides. The light is used in the form of ultraviolet radiation (UVA, UVB, UVC), as this radiation is particularly suitable for killing bacteria or microscopic harmful microorganisms. The light can also come from the visible range of the spectrum. The method comprises distributing at least one light guide in an area containing the liquids or gases to be disinfected. This is followed by aligning at least one radiation unit with a light source of high intensity and then irradiating the liquid or the gas over a predetermined period of time. The radiation unit is designed in the form of a laser.

In the pamphlet EP 2 273 004 B1 describes a cabinet for cleaning clothes, the cabinet having a cleaning space for the clothes to be cleaned and means for generating ozone from air. The ozone is brought into the cleaning room and brought into contact with clothing. The closet has an equipment room in which ozone is generated for cleaning the clothes and supplied to the clothes. The equipment room is separated from the cleaning room by a wall.

A device for sterilizing shoes is from the document U.S. 4,981,651 A known. The device comprises an elongated lamp for emitting ultraviolet radiation in a housing as well as a heating element and a fan. The device can be introduced into a shoe, with sterilization of the shoe sole being achieved by means of the lamp and the heating element. The growth of fungi and bacteria is stopped. However, only air circulation within the UV radiation source is described, but not in the chamber around it. An extraction system and a filter are not disclosed.

A similar device is shown in US 2016/0339126 A1 (D1). UV sources are arranged therein in a housing, which are at least partially introduced into textiles to be cleaned. Extraction is not provided here.

Out U.S. 3,877,152 A there is a chamber for treating textiles with an air supply, a heating source and a UV radiation source with which ozone is generated. A vacuum can be applied to the chamber.
The document too CH 359 113 A describes a chamber to which a vacuum is applied, creating a flow of air. The vacuum is used to remove the ozone and the dirt particles loosened from the laundry.

From the pamphlet DE 10 2012 209 823 A1 a method and a device for cleaning textiles are known, these being inserted through an opening into the chamber of a household appliance. Air is introduced into the chamber of the dryer. The air is irradiated with UV-C light, 100 to 280 nm, with an ozone generator provided for this purpose being arranged outside the chamber. There is no efficient cleaning of the interior areas of the garments or with this solution the surface of other materials or objects is possible.

document DE 10 2007 037 984 A shows a device with an air circulation and an ozone source which can be introduced into the textiles. The air can flow through the tissue. A separation device removes ozone and dirt particles. The UV source is located at the end of the air supply on the chamber side, but the air flow is not split up for several UV radiation sources. Furthermore, no change in pressure is provided.

From the pamphlet US 2009/0193676 A1 a device for drying shoes is known, which, however, separates the ozone generation and the UV radiation from one another.

With the aforementioned solutions, it is not possible to efficiently clean and disinfect items of clothing or the surface of other materials or objects such as blankets, mattresses, carpets and even soft toys or textile upholstery in or out of vehicles.

Furthermore, ozone in the air we breathe is harmful to health even in far lower concentrations; in particular, ozone pollution causes irritation of the respiratory tract.

In the pamphlet DE 11 2007 000 615 T5 a device for sterilizing human footwear is also described, which has a light source that emits radiation in a wavelength range that sterilizes the footwear,
by inhibiting or destroying the growth of microorganisms present in an internal area of the footwear; a support for the light source for placing it in position to direct the radiation onto the interior of the footwear; and a light blocker that prevents the radiation from harming a person located near the footwear during sterilization. Furthermore, this solution relates to a device for sterilizing human footwear with an opening into which the foot of a person is inserted in order to stand on the footwear, comprising: a light source which emits radiation in a visible wavelength range, which sterilizes the footwear by the growth of microorganisms present in an inner area of the footwear is inhibited; and a support for the light source for positioning it in a position to direct the radiation into the interior of the footwear to sterilize it.
The disadvantage of these two aforementioned solutions is that adhering impurities are not removed.

The object of the invention is to provide a device for cleaning and disinfecting at least one object, in particular at least one recess or at least one cavity in an object, whereby an environmentally friendly antibacterial cleaning is made possible without the use of chemical additives and the device has a simple structural design having.

This object is achieved with the characterizing features of the first claim for protection.

Advantageous configurations result from the subclaims.

2. b) dass durch wenigstens ein Mittel zur Ozonerzeugung Ozon erzeugt wird,
3. c) dass die Temperaturmodi einstellbar und/oder auswählbar sind,
4. d) dass der Druck einstellbar und/oder veränderbar ist.

Mittels eines von dem Gehäuse in die Kammer führenden Lufteinlasses und eines von der Kammer aus dem Gehäuse führenden Luftauslasses wird dabei ein Luftstrom innerhalb der Kammer erzeugt, der gezielt über die UV-Lampe geleitet und an bzw. in den zu reinigenden, insbesondere zu desinfizierenden Gegenstand geführt wird.According to one method, at least one object, in particular an item of clothing and / or at least one recess or cavity in the object, is cleaned and disinfected in that the object is received through an opening in a chamber surrounded by a housing on a receiving element, with at least three of the following techniques a) to d) are intelligently implemented in the chamber during a cleaning cycle:

1. a) that at least one UV-C lamp generates UV-C light in the non-visible wavelength range,
2. b) that ozone is generated by at least one means for ozone generation,
3. c) that the temperature modes are adjustable and / or selectable,
4. d) that the pressure is adjustable and / or changeable.

By means of an air inlet leading from the housing into the chamber and an air outlet leading from the chamber out of the housing, an air flow is generated within the chamber, which is directed over the UV lamp and onto or into the object to be cleaned, in particular to be disinfected to be led.

It is preferred to clean and disinfect objects that are made of textile material or that have textile material that can also be combined with other materials such as plastic, leather, etc.

The at least three techniques, which can be combined as desired from the aforementioned techniques a) to e), ensure a good one Cleaning result and significantly reduce contamination with bacteria and germs / microorganisms.
The at least three techniques used are preferably carried out simultaneously during a cleaning cycle. However, it is also possible to carry out the selected techniques one after the other in any order or alternatively.

A UV-C lamp is preferably used as the means for generating ozone, with which ozone is generated by emitting UV-C light, because the UV-C radiation forms ions that convert atmospheric oxygen into ozone. The ozone is extremely reactive and has a strong germicidal effect.
The UV-C lamp is preferably dimmable (for example by an upstream or integrated dimmer) so that the radiation intensity of the UV-C lamp can be changed depending on the degree of soiling of the objects to be cleaned. In the case of high pollution, a high intensity of the UV-C lamp and thus more ozone is generated; in the case of lower pollution, a lower intensity of the UV-C lamp and thus less ozone is preferably generated. The wavelength of the UV-C lamps is between 100 nm and 800 nm, preferably between 100 nm and 300 nm, particularly preferably between 150 nm and 280 nm.

The temperature modes of the device are in particular adjustable or changeable in such a way that the temperature in the chamber rises from a low temperature to a higher temperature, or is reduced from a high temperature to a lower temperature, or that the temperature alternately increases and decreases again or decreases and increases again. The temperature can be set and / or changed in a temperature range from -50 ° C to 100 ° C, preferably in a temperature range from -30 ° C to 60 ° C, particularly preferably in a temperature range between -10 ° C and 50 ° C be.
The temperature differences in particular loosen stubborn adhesions so that they can be loosened more easily.

Furthermore, a negative pressure and / or an overpressure can be generated in the chamber in relation to the atmospheric pressure. The pressure in the chamber can increase from a low pressure to a higher pressure or be reduced from a high pressure to a low pressure. It is also possible that the pressure in the chamber alternately increases and decreases again, or decreases and increases again.
The pressure in the chamber can be adjustable and / or changeable in a pressure range between 0.001 bar to 10 bar, in particular between 0.1 bar and 2 bar. To achieve such a pressure difference, the chamber within the housing can be hermetically sealed.
Dirt and other adhesions are loosened from the object to be cleaned due to the pressure differences.

It is also possible for silver nanoparticles to be introduced into the chamber from a reservoir; these can have a particle size of 1 nm to 1000 nm.
It is possible to only introduce the silver nanoparticles into the chamber after the other techniques have been completed, so that they lie over the surface of the object and thus offer future protection, since it has antibacterial properties or good bactericidal activity.

In a cleaning cycle, heated or cooled air is advantageously introduced into the chamber and irradiated in the chamber with ultraviolet light from at least one UV-C light source. By means of the UV-C light source, ozone is generated in the chamber, thereby disinfecting and cleaning the at least one object, the UV-C light source being at least partially introduced into the recesses or the cavity of the object. An alternating pressure is generated in the chamber by means of a suction device, whereby soiling of the object is loosened and the dirt particles are transported away.
In an advantageous embodiment, the air flow can be heated by means of a heating element in the area of the intake. The heating element is preferably integrated into the duct in the form of a heating fan.

Particularly preferably, water vapor is added to the air stream in the area of the inlet into the chamber, whereby a smoothing effect is exerted on the textiles. The ironing of the garments can then be omitted.

The water vapor is generated in a water tank with an integrated heating element. A fragrance is preferably added to the air stream and / or the chamber. The fragrance elements can be interchangeable and available in different fragrances.

In this way, extremely reliable cleaning and disinfection of the object is achieved. In particular, recesses and cavities present in the object or clothing can be cleaned and disinfected if the UV lamp is at least partially introduced into them. Because the pressure differences also act in the cavities and the temperature in the chamber is cooled or heated (possibly also alternately), cavities and recesses in items of clothing (such as the inside of Shoes or gloves), or bags, rucksacks, helmets, crash helmets, hats, baseball caps and other equipment cleaned and disinfected. It is particularly advantageous if these objects are made of or have textile material and cannot be washed or can only be washed to a limited extent.

Depending on the space available, the chamber can be pulled out of the housing by means of a rail system, or it can have a front door.

The method according to the invention is used in particular to clean and disinfect textiles, in particular cavities and textile fabrics formed by textiles, the textiles (or at least one textile) being inserted through an opening into a chamber formed by a housing. In a first process step, temperature-variable air, preferably heated or cooled air, is preferably introduced into the chamber and then the textile / s are irradiated with ultraviolet light from at least one UV source, the UV source generating ozone in the chamber and disinfection and cleaning of the textiles (objects) takes place. The cavity formed by at least one textile is arranged on at least one UV source in such a way that the UV source can at least partially be introduced into the textiles or can be positioned close to the textile. The germs and bacteria are killed by the combination of UV radiation and the ozone formed, which means that the textile in question can be disinfected. The cleaning effect is improved by the temperature and pressure in the chamber.
The generated ozone is removed by a filter placed in the area of the suction device, when the cleaned air is sucked out or expelled from the chamber by means of the suction device.

In the chamber, by means of the suction device, a negative pressure up to a vacuum is alternately generated, by means of which dirt is loosened in the textiles and loosened dirt particles are removed by means of suction.

The UV source works with a wavelength of the ultraviolet radiation in the non-visible UV-C range, the wavelength being 100 nm and 800 nm, preferably between 100 nm and 300 nm, particularly preferably between 150 nm and 280 nm. The use of infrared radiation is also conceivable.

Air enriched with fragrances can preferably be supplied to the chamber. In this way, the textile to be cleaned or the object can be provided with a pleasant smell.

The device is used to clean textiles, in particular textiles contaminated with germs, bacteria and fungi, the device having a housing and a chamber arranged in the interior of the housing with a receiving element for textiles or objects. The device has an air supply pointing from outside the housing into the interior of the chamber with at least one heating and / or cooling element extending along the air supply. At least one UV lamp is arranged on the receiving element, the UV lamp being provided for generating UV radiation such that ozone can be generated in the chamber. Furthermore, the device has a suction device for generating a negative pressure in the chamber, whereby the air and dirt particles can be sucked or conveyed out of the chamber, the generated / used ozone being removed by a filter in such a way that cleaned air is expelled.

In an advantageous embodiment, the suction device is dimensioned such that it can generate a vacuum in the chamber. In this way, dirt and germs can be removed from the textiles.
A feed for silver nanoparticles and / or fragrances is preferably provided on the device. The silver nanoparticles are used to prevent bacterial growth.

The silver nanoparticles and / or fragrances can be introduced into the chamber. Preferably, the silver nanoparticles and / or fragrances are introduced directly into the cavity (s) formed by the textile (s). This is preferably done via the air supply.

The air that can be introduced into the chamber can be heated by means of a heating coil which is arranged around the air supply or cooled by a cooling device. A fan is preferably arranged at the housing-side end of the air supply, which sucks the air and conveys it into the chamber. A combined fan heater can also be used
The suction takes place in a similar way, with a second fan sucking the air out of the chamber and releasing it into the environment.

The cleaning cycle can preferably be set by means of a control unit, with individual or all parameters being adaptable. The parameters include the temperature and / or the pressure within the chamber and, if desired, the addition of fragrances and / or the silver nanoparticles. The chamber can also be used to dry the textiles. The device uses the spectrum of UV-C light as a UV source, whereby the combination of UV radiation, ozone, temperature programs and the use of vacuum air exchange eliminate bacteria and fungi. The parameters can be determined automatically by the device by entering properties of the object to be cleaned. These properties include, for example, the type of material, degree of soiling, degree of moisture or the like.
The adjustable temperature programs include the option of heated or strongly cooled air that is directed to the cleaning locations to be used. The ozone is synthesized directly at the UV-C source, the UV lamp, ie synthesized and used in the desired area of application.
The vacuum-air-exchange system removes dead, living and eliminated organisms from the textiles.

The chamber has an antibacterial and antifungal effect during the cleaning cycle and, in particular, cleans the inside of the products. The disinfection and cleaning takes place without the addition of chemicals, which means that it is environmentally friendly and gentle on materials. The use of steam means that only a small amount of water is required for cleaning.
The chamber is preferably used to clean the inside of shoes, helmets, gloves, sports equipment, T-shirts, shirts, suits (items of clothing) or bags, as these textiles are only partially or not at all suitable for the washing machine and subsequent drying.

The device and the chamber arranged therein are designed in such a way that textiles fit into it without problems and without creasing and can be arranged or hung up therein. The dimensions in terms of width, height and depth are preferably 30/120/60 cm. An increase in the dimensions has no effect on the effectiveness of the mode of operation. The device should preferably not fall below the dimensions mentioned.

The device according to the invention is antibacterial and acts against various types of mites, such as house mites and scabies, and against fungi in the form of athlete's foot or skin fungus.

The fact that heated / cooled air in the aforementioned temperature range is passed into the chamber by means of the air supply and the UVC radiation source is positioned at the chamber-side end of the air supply and the UVC radiation sources are introduced into the textiles or are positioned close to them a better penetration of the textiles with the ozone is guaranteed by the air flow acting directly on it than in the prior art, and a better cleaning or disinfecting effect is thereby achieved.

This effect is further improved if the receptacles for the objects to be cleaned are connected to a chamber-side end of the air supply by means of at least one adapter, as is done here by dividing the air flow within the chamber with the at least one adapter through which the air flow is directed.

In any case, for example, only one or two or even more first adapters can then be used 4.5 or one or two or even more second adapters or a different number and combination of adapters can be used, depending on which object is to be cleaned.

According to 5 and 6 is the water tank 7th with a heating element (not shown) arranged therein in the area of the transition between the chamber-side end 3.3 the air supply and the first and second adapters 4.5 , 4.6 arranged, here in the area of the air duct 4A . The water is heated in such a way that water vapor is produced, the water vapor being supplied via an unmarked line of the air supply 3 is fed.
There is a mixing of heated air and the generated water vapor, with the mixture over the chamber-side end 3.3 is fed to the cavities formed in the adapters and is guided via these to the UVC radiation sources.
The air, which is enriched with moisture, smooths the item of clothing to be cleaned, eliminating the need for later ironing.

It is also possible to use a special ironing liquid so that instead of water the ironing liquid enters the schematically indicated water tank 7th is filled.

The smoothing of the textiles by means of steam is preferably carried out after the UV radiation sources have been switched off and thus after the textile has been treated with the UV radiation.

For more effective cleaning, the air is in the area of the air supply 3 heated or cooled as already described or alternately heated and cooled. This is in the area of the air supply 3 the heater 3.4 arranged. Alternatively, a fan heater can be used as a combination of heating device 3.4 and fan 3.2 can be used. The through the air supply 3 flowing air is in the area of the heater 3.4 heated or cooled.
The temperature can be set and / or changed in a temperature range from -50 ° C to 100 ° C, preferably in a temperature range from -30 ° C to 60 ° C, particularly preferably in a temperature range between -10 ° C and 50 ° C.

In an advantageous embodiment is in the area of the air supply 3 a fragrance capsule 8th to create a fresh scent for the textiles in the air supply 3 arranged. The released fragrances can with that of the air supply 3 sucked air is added and into the chamber 2 be directed.

According to the previous figures, the chamber 2 according to the embodiment in FIG 5 and 6 a suction device 6 in the ceiling area of the chamber 2 on. The suction device 6 is preferably arranged in the upper area of the device and has an upwardly directed air outlet leading to the outside 6.1 on, in which also a fan, not shown. The suction device 6 can also be supplemented with a replaceable filter, not shown, so that the polluted air can be cleaned before it leaves the chamber and the ozone can be removed. The filter is preferably in the area of the fan and the suction device 6 arranged.

Also according to the 5 and 6 can with the suction device 6 and the air supply 3 a changing pressure in the chamber 2 can be achieved with the suction device 6 can be designed such that there is also a vacuum in the chamber 2 can be generated. The chamber is for such a configuration 2 preferably airtight.

Then are in the undesignated top of the cabinet body 1a Outlet openings 6.1.1 through which the extracted air can escape. When the housing is pushed in 1 are the outlet openings 6.1.1 of the cabinet body 1a above the air outlets 6.1 in the lid D. of the housing 1 .

Furthermore is in the area of the floor B. the chamber 2 an additional printing system 11 possible, by means of which the air supply 3 and the suction device 6 to generate a negative or positive pressure is supported.

The pressure in the chamber 2 can be adjustable and / or changeable in a pressure range between 0.001 bar to 10 bar, in particular between 0.1 bar and 2 bar.

The use of a filter is particularly recommended because even low concentrations of ozone leaking are harmful to health due to irritation of the respiratory tract.

7th shows a representation similar to 6 but without a cover in the drawer and instead with cross braces 12 between the pages S1 and S2 which the sides S1 , S2 Stabilize each other and ensure that the objects to be cleaned do not come out of the housing 1 protrude and prevent it from being pushed into the body. It is here possible to insert the objects to be cleaned from above.
The suction, not shown here, is then as in 1 in the front side panel S2 or in the rear side part S2 arranged, then in the cabinet body 1a there are corresponding air outlets in the rear wall.
In this variant it is indicated that the air duct 4A provided the first and second adapters 4.5 and 4.6 connect releasably.

Instead of cross struts, one or more plate-like elements can also be located between the side parts S1 , S2 extend.

Such cross struts or plate-like elements can also be used in the variants described above.

Furthermore, it is in accordance 7th possible that, for example, the first adapter 4.5 in the two upwardly extending areas of the air ducts 4.5.1 one joint each G1 and G2 having. The area shown here, for example in an initial position, extends vertically upwardly around a horizontal axis A1 , A2 designed to be pivotable, which is indicated by the double arrows. This allows the upper ends of the two air ducts 4.5.1 of the adapter 5.5 be pivoted towards and away from one another and thus their distance can be adapted to the objects to be picked up.

With the device according to the invention, the air flow supplied to the chamber is divided up in the chamber via the channels which are formed by the adapter elements and in each case to a UV radiation source 5 guided.

The number of channels formed in an adapter corresponds to the number of UV radiation sources 5 provided on the adapter

It is therefore also possible to provide an adapter not only with two, but also with three, four or more upwardly extending branches, each of which sends the air flow to a UV radiation source 5 to lead.

The UV radiation source is preferably located 5 at the air outlet areas of the adapter.

The adapters also form the receptacles for the objects to be cleaned.
The adapters can be designed in such a way that the distance between the upper areas, which receive the objects to be cleaned, can be changed.

It is possible to arrange several of the essentially cuboid devices according to the invention next to one another and / or one above the other in the manner of a battery.
The devices can also be connected to one another.

It is also alternatively possible to provide a cabinet body with a pivotable or laterally displaceable door, the chamber / cleaning chamber then being formed in the cabinet body.

Depending on the textile to be cleaned, the individual parameters such as pressure, temperature, UV radiation and ozone can be set. For example, when cleaning leather, it is advisable to use the maximum power of the device, while cashmere, for example, should only be treated gently.
