Description

The present invention relates to disinfection furniture for receiving objects to be disinfected, having at least one lockable interior, at least one receiving element arranged within the interior when the interior is closed, at least one occupancy sensor and at least one irradiation device.

Ultraviolet radiation in the UV-C range with a wavelength of 100 nm to 280 nm is often used in the field of physical disinfection technology due to its damaging effect on nucleic acids. This makes use of the fact that exposure to UV-C rays leads to the inactivation of most viruses and bacteria. Such a disinfection of surfaces is useful, for example, for cash register systems or other storage containers in public areas.

In addition, ozone is generated by UVC radiation in connection with oxygen, which inactivates odor molecules and organic pollutants in the air.

The pamphlet DE 20 2018 103 840 U1 describes a device for cleaning and disinfecting at least one object, the device having a chamber which is surrounded by a housing and in which the object is suspended on a receiving element. In one embodiment, the device has a UV lamp arranged in the chamber on the receiving element for generating UV-C light in the non-visible wavelength range. When the device is closed, it cannot be seen whether there is an object in the chamber.

The pamphlet WO 2008/040316 A1 discloses a method for disinfecting objects in the household sector and a corresponding household disinfection device with a source provided in a closable housing, which emits ultraviolet rays and wherein the rays are directed onto the object or objects to be disinfected by scattering or reflecting the radiation and / or the source movably encircles the objects to be disinfected in the housing. Here, too, there is no possibility of recognizing an occupancy of the housing or an opening state.

Some publications, such as the WO 2015/032694 A1 or the WO 2007/089312 A2 disclose a device with a disinfection chamber closed by a flap, in which a sensor detects the opening state of the flap.

The pamphlet DE 203 08 499 U1 discloses an endoscope storage cabinet with UV radiation. The door is monitored and locked by an electronic control system. Whether or not there are objects in the endoscope storage cabinet cannot be recognized by the user without opening the door, whereupon the irradiation would be interrupted.

The invention is therefore based on the object of creating a disinfection furniture in which suspended or inserted objects are disinfected without the user having to switch the irradiation on or off manually.

This object is achieved on the one hand by a disinfection furniture for receiving objects to be disinfected, having at least one lockable interior, at least one receiving element arranged within the interior when the interior is closed, at least one means for detecting an occupancy of the interior and at least one irradiation device, wherein according to the invention the Irradiation device irradiates the interior with UVC radiation when the means for detecting an occupancy state of the interior detects the presence of at least one object to be disinfected in the interior.

The disinfection furniture can be designed as a roll container, as a cabinet, as a sideboard or as a comparable storage furniture. The interior space can be completely enclosed by a housing, at least one opening being able to be closed by a flap, a door and / or a pull-out. In particular, the interior is delimited from the outside in a light-tight manner.

One or more objects can be introduced into the interior.

The disinfection furniture has at least one agent for detecting an occupancy state of the interior, by means of which it can be detected whether there are objects in the interior. As soon as there are objects in the interior space, this and thus also the objects located therein are irradiated with UVC radiation by the irradiation device. The UVC radiation has an antibacterial and virucidal effect on the surface of the treated objects.

Since the irradiation is only activated when at least one object is present in the interior space, energy can advantageously be saved which would be necessary for irradiating an empty interior space. Due to the at least one means for detecting an occupancy state of the interior space, the irradiation advantageously does not have to be switched on or off manually by a user, which significantly increases the efficiency of the disinfection furniture.

It is also advantageous that the irradiation is only activated when the opening (s) of the disinfection furniture are also closed, in order to avoid endangering people from the UVC radiation. To ensure this, one or more sensors can be present in order to detect the opening state of the disinfection furniture.

In a preferred embodiment, the means for detecting an occupancy state of the interior space is an occupancy sensor and / or a scale.

This can be an optical sensor, such as an infrared sensor, an ultrasonic sensor, or a weight sensor and / or a measuring device for determining a mass.

The at least one receiving element is preferably designed as a holding rod for hanging objects to be disinfected. The holding rod can be made of stainless steel or another antibacterial material.

Objects to be disinfected can be hung on the holding rod, which advantageously enables all-round irradiation of the objects and no possible contact surface for the objects is not reached by the radiation.

In order to continue to ensure irradiation on all sides, it is also advantageous if the interior has several irradiation devices and / or is equipped with a reflective material on its inner walls. Furthermore, it is conceivable that one or more reflection units are arranged in the interior space in order to ensure / support a uniform distribution of the UVC radiation emitted by the irradiation source (s).

The disinfection furniture advantageously has at least one pull-out.

In a preferred embodiment, the pull-out has at least one side wall that can be pulled out of the disinfection furniture and at least one receiving element is arranged on the pull-out side wall.

In this embodiment, the receiving elements can advantageously be equipped with objects outside of the interior space and thus more easily accessible to a user. A receiving element arranged on an extendable side wall can be, for example, a holding rod or a clamping device.

In a further preferred embodiment, the pull-out has at least one base that can be pulled out of the disinfection furniture and at least one receiving element is arranged on the pull-out base. In this embodiment too, objects can simply be arranged on the receiving element (s) while they are located outside the interior. The receiving element can be, for example, holding rails for setting flat objects such as tablets, and / or a clamping device and / or a combination of both.

Furthermore, the disinfection furniture can have several pull-outs or a combination of pull-out / pull-outs and one or more flaps or doors.

As a result, different areas of the interior of the disinfection furniture can advantageously be made accessible from the outside and filled. For example, an extendable side wall with holding bars and an extendable floor with holding rails could be formed.

The disinfection furniture can also have several interiors that are separated from one another.

In this way, different objects can advantageously be accommodated in different areas of the disinfection furniture.

In particular, a separate irradiation device and / or a separate means for detecting an occupancy state of the interior space is arranged in each interior space.

As a result, partial areas of the disinfection furniture can advantageously be irradiated individually and thus the irradiation can be made more efficient.

It is also conceivable that individual pull-outs / areas of the disinfection furniture cannot be opened via an automatic locking mechanism as long as (other) certain pull-outs / areas are not yet fully occupied or as long as (other) certain pull-outs / areas are not yet completely empty. This will prevent several areas for the same type of object are each only partially occupied and have to be irradiated separately, whereas irradiating only one fully occupied area would be more energy-efficient.

An embodiment would also be conceivable in which the irradiation of a partial area does not begin until this partial area is completely occupied.

The irradiation device preferably emits radiation with a wavelength of 240 nm to 280 nm, preferably 250 nm to 260 nm, particularly preferably 254 nm, into the interior.

At the wavelengths mentioned, the UVC rays have a particularly harmful effect on viruses and other microorganisms and the irradiated surfaces are effectively disinfected.

The irradiation device is also preferably designed as a UVC LED lamp.

The irradiation device can be designed so that it can be switched on and / or switched off manually.

Furthermore, the disinfection furniture can have a display device by means of which a user can visualize the data acquired by the means for acquiring an occupancy state of the interior space. Based on the data read, the user can make the decision to switch the irradiation device on and / or off.

The disinfection furniture advantageously has at least one battery and / or an accumulator for power supply and / or a connection point for a power cable. In particular, when it is powered by a battery and / or an accumulator, the disinfection furniture can be designed to be mobile.

For a mobile design of the disinfection furniture, further features, such as an arrangement on castors, can be provided.

The disinfection furniture according to the invention would be useful, for example, in environments in which objects are used by a large number of people and are to be disinfected after use. This could be the case, for example, in museums, in which audio guides, tablets or other objects issued to the visitors for the museum visit are returned by them after the visit. The visitors could deposit the objects in an appropriate disinfection furniture without being aware of the exact functionality of the disinfection furniture. The disinfection furniture automatically detects whether there are objects to be disinfected in its interior and starts the disinfection process without further action from the outside, or ends it when all objects have been removed. This can save energy and thus costs.

Another possible area of application would be, for example, medical and / or therapeutic and / or other public facilities in which medical or other objects are regularly used and then deposited again at a specific storage location. This can be advantageous for several, but also for only one user, for example a doctor in a practice or a beautician in a cosmetic studio, who is spared the conscious and active disinfection of certain objects in his work routine.
