Description

Method and device for cleaning and disinfecting objects

The invention relates to a method and a device for cleaning and disinfecting objects according to the preamble of claims 1 and 13, and particularly for cleaning and disinfecting textile-containing objects such as clothing, shoes, sports equipment, backpacks or helmets and the like Application and thus in particular of objects or items of clothing which are preferably worn on the body and also of blankets, mattresses, carpets and also soft toys or textile upholstery in or out of vehicles

Such objects or textiles are preferably to be cleaned by means of a washing machine and then drying in a tumble dryer, soiling, germs, bacteria and fungi being removed. In nature, bacteria and fungi feed on the sweat and dead skin particles released by humans. A gas is excreted as a digestive product, which is perceptible as an unpleasant smell. However, not all products associated with sweat or other odorous substances (smoke or food) can be cleaned in the washing machine, or the material suffers from too many washing cycles. For example, shoes, in particular sports shoes, gloves (especially if they have leather), helmets and the like should not or cannot be washed completely in a washing machine or by hand.

Irradiation with ultraviolet light can kill bacteria in liquids and substances and inactivate or destroy many organisms. This can be seen as disinfection of 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 document DE 698 01 450 T2 a method for disinfecting liquids and gases as well as devices for using the mentioned method is known. The publication relates in particular to methods for disinfecting liquids and gases by light, which is radiated into the liquids and gases by light guides. The light is in the form of

Ultraviolet radiation (UVA, UVB, UVC) is used because 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 that contains the liquids or gases to be disinfected. This is followed by alignment of at least one radiation unit with a light source of high intensity and subsequent irradiation of the liquid or the gas over a predetermined period of time. The radiation unit is designed in the form of a laser. In the document EP 2 273 004 B1, a cabinet for cleaning clothes is described, the cabinet having a cleaning room for the clothes to be cleaned and means for cleaning

Generates ozone from air. The ozone is brought into the cleaning room and brought into contact with the clothing. The cabinet has an equipment room in which ozone is generated for cleaning the clothing and supplied to the clothing. The equipment room is separated from the cleaning room by a wall.

A device for the sterilization of shoes is known from US 4,981, 651 A. The device has an elongated lamp for emitting ultraviolet radiation in a housing and a heating element and a fan. The device can be inserted into a shoe, 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. Suction and a filter are not disclosed.

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

US 3 877 152 A discloses 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 CH 359 113 A also describes a chamber to which a vacuum is applied and an air flow is thereby generated. The vacuum is used to remove the ozone and the dirt particles detached from the laundry.

From the document DE 10 2012 209 823 A1, a method and a device for cleaning textiles are known, these being through an opening in the chamber of a

Household appliance be inserted. 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 outside the chamber. With this solution it is not possible to efficiently clean the interior of the garments or the surface of other materials or objects.

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 separating device removes ozone and dirt particles. The UV source is located at the end of the air supply on the chamber side, although the air flow is not divided for several UV radiation sources. Furthermore, no change in pressure is provided. A device for drying shoes is known from the publication US 2009/0193676 A1, which, however, separates the generation of ozone and the UV radiation.

It is not an efficient cleaning and disinfection of the above solutions

Garments or the surface of other materials or objects such as blankets, mattresses, carpets and also soft toys or textile upholstery in or out of vehicles are possible.

In addition, however, ozone in the air we breathe is already harmful to health in far lower concentrations; in particular, the ozone load causes irritation of the respiratory tract.

The document DE 11 2007 000 615 T5 also describes a device for sterilizing human footwear, 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 inner area of the footwear; a support for the light source to place it in a position to direct the radiation onto the inner region of the footwear; and a light block that prevents 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 one

A person is used to stand on the footwear, comprising: a light source that emits radiation in a visible wavelength range that the footwear

sterilized by the growth of microorganisms in an inner area of the

Footwear is present, is inhibited; and a support for the light source to place it in position to direct the radiation into the inner area of the footwear to be sterilized.

The disadvantage of these two aforementioned solutions is that adhering contaminants are not removed.

The object of the invention is to provide a method and a device for cleaning and disinfecting at least one object, in particular of at least one recess or at least one cavity in an object, which enables environmentally friendly antibacterial cleaning without the use of chemical additives and the device unites has a simple construction.

This task comes with the distinctive features of the first and thirteenth

Claim resolved.

Advantageous refinements result from the subclaims. According to the method, the cleaning and disinfection of at least one object, in particular a piece of clothing and / or at least one recess or one

Cavity in the object in that the object is received through an opening in a chamber surrounded by a housing on a receiving element, wherein in the chamber at least three of the following techniques a) to d) are intelligently implemented during a cleaning cycle: a ) that by means of at least one UV-C lamp UV-C light in the invisible

Wavelength range is generated

b) that ozone is generated by at least one means for generating ozone, c) that the temperature modes can be set and / or selected,

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 inside the chamber, which is directed specifically over the UV lamp and onto or into the object to be cleaned, in particular to be disinfected to be led.

Objects are preferably cleaned and disinfected, which consist of textile material or which have textile material which also with other materials such as

Plastic, leather, etc. can be combined.

The at least three techniques, which can be combined as desired from the aforementioned techniques a) to e), ensure a good 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 alternately.

A UV-C lamp is preferably used as the means for generating ozone, with which UV-C light is used to generate ozone, because the UV-C radiation forms ions which 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 contamination of the objects to be cleaned. At a high

Contamination creates a high intensity of the UV-C lamp and thus more ozone, with less pollution a lower intensity of the UV-C lamp and thus less ozone is preferred. 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 such 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 rises and falls alternately or decreases and rises 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 his.

The temperature differences in particular remove stubborn build-up so that they can be removed more easily.

Furthermore, a negative pressure and / or an excess pressure can be generated in the chamber with respect to the atmospheric pressure. The pressure in the chamber can increase from a low pressure to a higher pressure or can be reduced from a high pressure to a low pressure. It is also possible for the pressure in the chamber to rise and fall alternately or to drop and rise 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 can be sealed airtight within the housing.

The pressure differences remove dirt and other buildup from the object to be cleaned.

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 introduce the silver nanoparticles into the chamber only 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 has 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 suction device is used in the chamber

Generates pressure, which loosens dirt on the object and removes the dirt particles.

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 in the channel in the form of a fan heater. Water vapor is particularly preferably mixed into the air flow in the region of the feed into the chamber, as a result of which a smoothing effect is exerted on the textiles. The ironing of the clothes 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 scents. This ensures extremely reliable cleaning and disinfection of the object. 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. Due to the fact that the pressure differences also act in the cavities and the temperature in the chamber is cooled or warmed (if necessary alternately) cavities and recesses of clothing (such as the inside of shoes or gloves), or also of bags, backpacks, Helmets, crash helmets, hats, baseball caps and other equipment cleaned and disinfected. It is particularly advantageous if these objects consist of or have textile material and cannot be washed or can only be washed to a limited extent.

The device for cleaning and disinfecting at least one object, in particular a piece of clothing or at least one recess or cavity in one

Object, has a chamber surrounded by a housing, in which the

The object is suspended from a receiving element, the device according to the invention having at least three of the following means A) to D):

A) at least one UV lamp arranged in the chamber on the receiving element for generating UV-C light in the invisible wavelength range,

B) at least one means for generating ozone,

C) at least one device for setting and / or changing the temperature in the chamber,

D) at least one device for adjusting and / or changing the pressure in the chamber.

Furthermore, the device has an air supply, which points from the outside of the housing into the interior of the chamber, with an air inlet and with at least one heating element which extends along the air supply and an air outlet which extends from the chamber out of the housing.

A fan is preferably arranged on the air inlet and the air outlet, which draws air away or sucks it off. The device can, for example, have all of these means A) to D), with which, as required, at least three of the techniques which can be carried out with it are implemented during a cleaning cycle.

At least one UV lamp for generating (not visible) UV-C radiation and for generating ozone is advantageously arranged on the receiving element in the form of a bracket arranged in the chamber. Furthermore, the device has the suction device for generating a negative pressure in the chamber. With this suction device, the dirt particles detached from the object are also suctioned off.

At least two UV lamps on the receiving element are advantageous

arranged side by side and spaced from each other, the UV lamps in particular being dimmable.

In an advantageous embodiment, the width of the receiving element is adjustable. This is preferably carried out by means of carrier elements which can be moved outwards and which are infinitely variable or adjustable by means of rastering.

The receiving element can be removed and / or exchangeably fastened in the chamber. The object can be conveniently fixed outside the chamber on the receiving element and then hung in the chamber.

The cleaning cycle can advantageously be set by means of a control unit and the parameters such as temperature and / or pressure and / or addition of fragrances and / or silver nanoparticles can be set.

In an advantageous embodiment, a fragrance element is arranged in the air supply. The fragrance element can be adjustable in such a way that the desired intensity of the fragrance of the clothing or the textile is adjusted.

The device preferably has a water tank with a heating element such that water vapor can be generated and that the water vapor can be supplied to the air supply via a channel. A combined air stream of heated air and water vapor is thus introduced into the chamber.

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, for cleaning and disinfecting textiles, in particular voids and textile fabric formed from textiles, the textiles (or at least one textile) through an opening in a housing formed chamber are inserted. In a first process step, temperature-variable air, preferably heated or cooled air, is preferably introduced and then the textile (s) is irradiated with ultraviolet light from at least one UV source, with ozone being generated in the chamber by means of the UV source and disinfection and cleaning of the textiles (objects). 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 be at least partially introduced into the textiles or positioned close to the textile. The germs and bacteria are killed by the combination of UV radiation and the ozone formed, whereby disinfection of the textile in question can be implemented. The cleaning effect is through the

Temperature and pressure in the chamber improved.

The ozone generated is removed by a filter placed in the area of the suction device when the cleaned air is extracted or expelled from the chamber by means of the suction device.

In the chamber, the suction device alternately creates a vacuum or vacuum, by means of which a loosening of dirt in the textiles and a

Loosened dirt particles are removed by suction.

The UV source works with a wavelength of the ultraviolet radiation in the invisible 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. The textile or the object to be cleaned 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 comprising a housing and an inside of the

Has housing arranged chamber with a receiving element for textiles or objects. The device has an air supply, pointing from the outside of 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 in such a way that ozone can be generated in the chamber. Furthermore, the device has a suction device for generating a negative pressure in the chamber, as a result of which the air and dirt particles can be extracted or conveyed from the chamber, the generated / used ozone being removed by a filter such that cleaned air is expelled. In an advantageous embodiment, the suction device is dimensioned such that it can create a vacuum in the chamber. This allows dirt and germs to 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. The silver nanoparticles and / or fragrances are preferably 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 spiral, which is arranged around the air supply, or can be cooled by a cooling device. A fan is preferably arranged at the end of the air supply on the housing side, which sucks the air in and conveys it into the chamber. A combined fan heater can also be used

The extraction takes place in a similar manner, with a second fan drawing 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, individual or all parameters being adaptable. The parameters include the temperature and / or 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, with the combination of UV radiation, ozone, temperature programs and vacuum-air exchange use eliminating bacteria and fungi. The device can independently determine the parameters by entering properties of the object to be cleaned. These properties include, for example, the type of material, degree of contamination, degree of moisture or the like.

The adjustable temperature programs include the possibility of heated or also 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, i.e. at the desired one

Scope synthesized and applied.

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. Disinfection and cleaning takes place without the addition of chemicals, which results in a high level of environmental friendliness and material protection. By using steam, only a small amount of water is necessary for cleaning.

The interior of shoes, helmets, gloves, sports equipment, T-shirts, shirts, suits (clothing) or bags is preferably cleaned with the chamber, since these Textiles are only suitable to a limited extent or not at all for the washing machine and subsequent drying.

The device and the chamber arranged in it are designed in such a way that textiles fit in easily and without creasing and can be arranged or hung therein. The dimensions in terms of width, height and depth are preferably 30/120 / 60cm. Increasing the dimensions has no influence on the effectiveness of the mode of action. The device should preferably not fall below the stated dimensions. The device according to the invention is antibacterial and acts against various types of mites such as house mites and scabies mites and against fungi in the form of athlete's foot or skin fungus.

The fact that heated / cooled air by means of the air supply in the aforementioned

Temperature range is passed into the chamber 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, is a better penetration of the textiles with the ozone over those immediately acting on them Airflow guaranteed than in the prior art and it is thereby achieved a better cleaning or disinfecting effect. This effect is further improved if the recordings for those to be cleaned

Objects by means of at least one adapter with one end of the chamber

Air supply are connected, 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. The invention is explained in more detail below using an exemplary embodiment and associated drawings.

The device comprises a housing 1 that forms a chamber 2 in its interior, the chamber 2 preferably being insertable and extractable into a cabinet body 1 a enclosing the housing 1 via a rail system (not shown). The

Cabinet body 1 a is open towards the housing 1 (via a vertically extending opening, not designated), so that the housing 1 can be inserted into it. Otherwise I shot the cabinet body below, above, on the sides and the back. That in the

Cabinet body 1 a retractable frame-like housing 1 with the chamber element / chamber 2 is preferably frame-like here. The housing 1 has a base B and a cover D, the base B and the cover D being connected to one another via two end-side vertical and parallel side parts S1, S2. The side part S1 is arranged in the direction of the cabinet body 1 a and the side part S2 opposite. The side part S2 closes the cabinet body 1 a when inserted. (See Figure 4)

Two spaced-apart covers A1, A2 extend between the side parts S1, S2 and the base B and the cover D (see FIG. 1). Each cover A1, A2 has a large opening, not designated, through which objects to be cleaned can be introduced into the chamber 2. As a result, the device can be fitted from two sides in the open state.

The fan 3.2 is designed in such a way that fresh air is drawn in from the surroundings and can be conveyed into the chamber 2 through the air supply 3.

The air supply 3 is preferably tubular and has an angle, preferably of 90 °, at its chamber end 3.3. The angle acts as a guide for the air, whereby a central outflow of the sucked-in air in the chamber 2 can be achieved.

At least one receiving element 4 is provided in the interior of the chamber 2 and is arranged hanging on the ceiling or in the region of the ceiling of the chamber 2. The receiving element 4 is designed in the form of a bracket and has a downward-pointing UV lamp 5 at each end, which generates the UV radiation required for cleaning.

In an alternative embodiment, the receiving element is designed in the form of at least one adapter, the receiving element being connected to the chamber-side end of the air supply and extending into the chamber. The adapter or the receiving element has an air duct, by means of which the air stream guided through the chamber-side end can be divided into a first and second air stream.

Depending on the design of the adapter, the outlet openings are arranged radially or axially with respect to the flow of air.

The wavelength of the UV radiation is preferably between 100 and 300 nm. The ultraviolet radiation is so short-wave and high-energy that it transmits

molecular oxygen (O2) is absorbed. The molecular oxygen (O2) is split into two free oxygen radicals (2 O '), which each react further with another molecule of oxygen (O2) to form ozone (O3).

The ozone thus formed on the UV lamp 5 disinfects the textiles against germs, fungi and bacteria.

Furthermore, the chamber 2 has a suction device 6 in the ceiling area of the chamber 2. The suction device 6 is preferably arranged in the upper region of the device, here at the top in the side part S2, and has, for example, an air outlet 6.1 leading through the housing 1 at its front, in which a second fan 6.2 is mounted. The fan 6.2 is designed in such a way that the air is sucked out of the chamber 2, as a result of which a suppression is created. An alternating pressure is reached in the chamber 2, and the suction device 6 can be designed such that a vacuum can also be generated in the chamber 2. The vacuum-air exchange system removes dead, living and eliminated organisms from the textiles. The suction device 6 with the air outlet 6.1 can be preceded by an exchangeable filter, not shown, so that the polluted air can be cleaned and the ozone removed before it leaves the chamber.

For a more effective cleaning, the air is heated or cooled in the area of the air supply 3 or alternately heated and cooled. For this method step, a heating device 3.4 is arranged in the area of the air supply 3, which is preferably wrapped around the air supply 3 in the form of a heating spiral. Alternatively, a fan heater can also be used as a combination of heating device 3.4 and fan 3.2. The air flowing through the air supply 3 is heated in the area of the heating device 3.4. Alternatively or additionally, a cooling element 6.1 can be provided in the area of the air supply 3.

The shoe 10 is attached to the receiving element 4 such that the opening of the shoe extends over the radiation source 5, the radiation source 5 in the interior of the Shoe 10 reaches into it. Thus, the inside of the shoe is penetrated by the UV radiation, germs and bacteria being killed off by means of the ozone formed in the shoe 10. Unpleasant smells caused by sweat and bacteria can thus be neutralized.

The device also offers the possibility to dry damp textiles gently in a short time.

With the device according to the invention, environmentally friendly cleaning and disinfection of the textiles is possible without the addition of chemical cleaning agents. Bacteria, germs and fungi are effectively eliminated.

Figure 3 shows a receiving element 4 in the form of a bracket with a receptacle 4.1 for hanging the bracket in the chamber. The width of the bracket can be adjusted, this preferably being done by means of carrier elements 4.2, 4.3 which can be moved outwards. The carrier elements 4.2, 4.3 are infinitely adjustable or, in particular, laterally adjustable by means of rastering, as a result of which the width of the bracket is adjusted to the different requirements or sizes of the textiles to be cleaned. The receiving element 4 also has connections 4.4 for contacting the UV lamps 5, two UV lamps being used here, for example.

In Figure 4, the device is shown in the closed state. The insert in the form of the housing 1 is inserted into the cabinet body 1 a, the side part S2 the

Cabinet body 1 a closes. A seal can be provided between the side part 1 and the cabinet body 1 a.

The side part S2 contains the display 9, the air inlet 3.1 and the air outlet 6.1. Alternatively, the air inlet 3.1 and the air outlet can also be located in the rear side part S1 (not shown), in which case the cabinet body 1 a should be open at least in these areas on its rear side (not shown).

The device is operated by means of the display 9 or also via an app.

It is possible to hang one or more hangers (receptacles 4) into the chamber 2, so that one or more items of clothing can be disinfected and refreshed at the same time.

According to FIGS. 5 and 6, the housing 1 has a chamber 2 with an air supply 3 with an air inlet 3.1 arranged in the front and an alternative receiving element 4. The receiving element 4 is designed in the form of a first adapter 4.5 and a second adapter 4.6, which are connected directly to the chamber-side end 3.3 of the air supply 3 and extend upwards in the chamber 2. The first and second adapters 4.5, 4.6 are hollow and have an air duct 4.5.1, 4.6.1, by means of which through which

chamber-side end 3.3 guided air flow per adapter 4.5, 4.6 can be divided into a first and a second air flow.

Exit opening 4.5.2, 4.6.2, according to FIG. 5, four exit openings, in the area of which one UV radiation source 5 is arranged. The outlet openings can be arranged radially or axially with respect to the individual air flow. In the present example according to FIG. 5, the first adapter is Y-shaped (Y) and has a first and second UV radiation source 5 at its chamber end. Such an adapter is particularly suitable for the positioning of textiles forming a cavity in the form of shoes or helmets, since these are placed or plugged onto a single UV radiation source 5 or two UV radiation sources 5.

The shape of the second adapter 4.6 differs from that of the first adapter 4.5 in such a way that the two air flows or air ducts are brought together again or are connected to one another. The shape of the second adapter 4.6 corresponds to a "Koppa"(<? Greek Alphabet). The UV radiation sources 5 are arranged in the area of the two separate air streams.

With an adapter of this type, textile objects can be hung without a further bracket.

Two adapters are preferably arranged in the chamber 2, two adapters of the first adapter type 4.5, two adapters of the second adapter type 4.6 or one adapter each of the first type 4.5 and the second type 4.6 being used.

The cabling for connecting the UV radiation sources 5 is preferably present in the first and second adapters 4.5, 4.6.

The adapters 4.5, 4.6 can have continuously symmetrical and / or asymmetrically distributed holes and / or passages for distributing the air or the water vapor.

A vertically extending area of an air duct 4A is provided over the area of the air supply 3.3 arranged in the chamber B in the floor B. At its upper end, the first and second adapters 4.5 and 4.6 are connected, which are channel-shaped and through which the air flow is further divided.

It is possible that the adapters 4.5 and 4.6 are formed in one piece with the air duct 4A and are detachably and interchangeably attached to the floor or that the adapters 4.5 and 4.6 are separately formed and detachably attached to the upper end of the air duct 4A.

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

According to FIGS. 5 and 6, the water tank 7 with a heating element (not shown) arranged therein is in the region of the transition between the chamber-side end 3.3 of the

Air supply and the first and second adapter 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 generated, the

Water vapor is supplied to the air supply 3 via a line which is not designated.

There is a mixing of heated air and the generated water vapor, the mixture being fed via the chamber end 3.3 to the cavities formed in the adapters and via which it is directed to the UVC radiation sources.

The air enriched with moisture smoothes the one to be cleaned

Garment, which makes later ironing unnecessary.

The use of a special ironing liquid is also possible, so that the ironing liquid is filled into the schematically indicated water tank 7 instead of water. 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 in the area of the air supply 3 is heated or cooled as described above or alternately heated and cooled. For this purpose, the heating device 3.4 is arranged in the area of the air supply 3. Alternatively, a fan heater can also be used as a combination of heating device 3.4 and fan 3.2. The through the

Air supply 3 flowing air is heated or cooled in the area of the heating device 3.4. The temperature is in a temperature range from -50 ° C to 100 ° C, preferably in one

Temperature range from -30 ° C to 60 ° C, particularly preferably in a temperature range between -10 ° C and 50 ° C adjustable and / or changeable.

In an advantageous embodiment, a fragrance capsule 8 is arranged in the area of the air supply 3 for generating a fresh scent of the textiles in the air supply 3. The fragrances released can be added with the air sucked in by the air supply 3 and passed into the chamber 2.

According to the preceding figures, the chamber 2 according to the exemplary embodiment in FIGS. 5 and 6 has a suction device 6 in the ceiling area of the chamber 2. The

Suction device 6 is preferably arranged in the upper region of the device and has an air outlet 6.1 directed upwards and leading to the outside, in which likewise a fan, not shown, is located. The suction device 6 can also be supplemented with an interchangeable 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 arranged in the area of the fan and the suction device 6.

According to FIGS. 5 and 6, an alternating pressure in the chamber 2 can be achieved with the suction device 6 and the air supply 3, wherein the suction device 6 can be designed such that a vacuum can also be generated in the chamber 2. For such a configuration, the chamber 2 is preferably made airtight.

It can be seen from FIG. 6 that the suction device 6 has one or more air outlets

6.1 can also be arranged in the cover D. Then there are outlet openings 6.1 .1 in the upper side of the cabinet body (not designated) through which the extracted air can exit. The outlet openings are in the inserted state of the housing 1

6.1 .1 of the cabinet body 1 a above the air outlets 6.1 in the lid D of the housing 1. Furthermore, an additional pressure system 11 is possible in the area of the bottom B of the chamber 2, by means of which the air supply 3 and the suction device 6 are supported to generate a negative or positive pressure.

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 ozone is harmful to health due to irritation of the respiratory tract even in low concentrations.

FIG. 7 shows an illustration, similar to FIG. 6, but without a cover in the insert and instead with cross struts 12 between the sides S1 and S2, which stabilize the sides S1, S2 to one another and ensure that the objects to be cleaned do not come out of the side of the housing 1 protrude and prevent insertion into the body. It is possible to insert the items to be cleaned from above.

The suction, not shown here, is then arranged as in FIG. 1 in the front side part S2 or also in the rear side part S2, with corresponding air outlets then being present in the cabinet body 1 a in the rear wall.

In this variant, it is indicated that the first and second adapters 4.5 and 4.6 are detachably connected to the air duct 4A.

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

Such cross struts or plate-like elements can also in the aforementioned

described variants are used.

It is also possible according to FIG. 7 that, for example, the first adapter 4.5 each has a joint G1 and G2 in the two upwardly extending regions of the air ducts 4.5.1. The area shown here, which extends vertically upward in an initial position, for example, is thereby designed to be pivotable about a horizontal axis A1, A2, which is indicated by the double arrows. This allows the top ends of the two

Air ducts 4.5.1 of the adapter 5.5 are pivoted towards and away from one another and their spacing is thus adapted to the objects to be picked up.

With the device according to the invention, the air flow supplied to the chamber is divided in the chamber via the channels which are formed by the adapter elements and each is guided to a UV radiation source 5. The number of channels formed in an adapter corresponds to the number of UV radiation sources 5 provided on the adapter

It is thus also possible to provide an adapter not only with two, but also with three, four or more branches which extend upwards and which each lead the air flow to a UV radiation source 5.

The UV radiation source 5 is preferably located 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 regions that accommodate 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, in which case the chamber /

Cleaning chamber is formed.

Depending on the textile to be cleaned, the individual parameters such as pressure,

Temperature, UV radiation and ozone can be set. When cleaning leather, for example, it is advisable to use the maximum power of the device, while cashmere, for example, should only be used with gentle treatment.
