Definitions
- Linen treatment cabinet with a device for treating the indoor air
- the invention relates to a laundry treatment cabinet comprising
- the device comprising a reactor space with a catalyst means mounted therein;
- a control device for activating and deactivating the unit for generating the process air.
- a laundry treatment cabinet with a device for treating the process air is known from EP 2267213 A1, the device comprising a treatment chamber and a flow generator for conveying the air through the treatment chamber, in which the air is photocatalytically treated. This treatment is carried out continuously, i.e. uninterruptedly, during the operation of the process air fan using an excitation light.
- the invention is therefore based on the object of providing a laundry treatment cabinet which provides improved and needs-based treatment of the laundry in a simple manner.
- the device for air treatment includes its own flow generator for conveying the air through the reactor space, in addition to the unit or the flow generator in the unit for providing the process air.
- the interior represents the treatment room for the laundry and cannot be moved relative to the housing or unit.
- the laundry is hung up in the interior, preferably by means of clothes hangers, with means being able to move the clothes hangers in order to improve the flow of the process air through the clothes.
- a Be provided steam generator in the closet to let steam into the interior, which in turn can act on the laundry.
- the movement of the clothes hangers and the activity of the steam generator are preferably controlled by the control device.
- the unit is arranged in the floor area of the cabinet, below the interior space, with the device for air treatment being arranged in the upper area of the cabinet, above the interior space.
- the process air is let into the interior from below and sucked out, with circulation of the process air being provided within the interior, which flows through the entire interior or at least almost reaches the entire interior.
- the laundry located in the interior is thus reached by the process air and dried or conditioned accordingly, for example with steam or a treatment agent.
- the air to be treated is sucked off through an inlet in the upper area of the interior and admitted into the reactor space. After treatment, the air from the reactor space is let back into the interior through the air outlet in the upper area of the interior.
- the air outlet is at a distance from the air inlet, preferably 10 cm to 50 cm.
- the air inlet is preferably arranged in the rear area and the air outlet in the front area or in the central area on the upper side of the interior. This ensures that the air to be treated circulates through the interior and that the process air is reached at least in a partial area. Overall, all position and direction information relates to the operational set-up position of the laundry treatment cabinet.
- control device is also set up to activate and deactivate the device for air treatment, independently of the control of the unit.
- the control device can be designed and programmed to activate and deactivate the device for treating the interior air based on a predetermined time sequence. This means that the activation times for the conditioning module are based on a predetermined schedule, so that the module is only active at certain times. This saves energy because the device is always inactive when no conditioning or sterilization of the process air is necessary.
- the control device is preferably set up to activate and deactivate the flow generator of the device.
- the storage cupboard comprises an operating device that is set up to provide a user input for the course of the activity of the device and to transmit it to the control device.
- a schedule can be specified by the user when the device for air treatment should be activated.
- the intensity of the air treatment can also be adjusted.
- the intensity and/or the duration of the air treatment can each be assigned to a specific type of laundry. After that, the user only needs to enter the type of laundry to be treated using the operating device, with the intensity and/or duration of the air treatment being set according to the assignment to the initialized type of laundry.
- the air treatment device includes the following:
- At least one activatable catalyst mat arranged in the reactor space which can be activated by means of radiation, preferably UV radiation;
- a fan for conveying the air from the interior through the reactor space, so that the catalyst mat flows through the air to be treated or is flown along the side;
- control device is suitably programmed and set up in such a way that the mark-to-space ratio between the switch-on time and the switch-off time determines the intensity of the air purification.
- This design is particularly easy to implement because time sequences that only include switching actuators on and off can be programmed and complex hardware changes are avoided.
- control device can be programmed and set up in such a way that the radiation means can be activated continuously with different power levels and the control device is set up to switch the corresponding power to the radiation means.
- This requires a possibility, for example a configurable amplifier or power switch, which receives a corresponding power value from the control device.
- the device includes a sensor for detecting the air quality, preferably a VOC (Volatile Organic Compounds) sensor, with which odors can be detected.
- the sensor is connected to the control device so that it can set the duration of the treatment and/or the intensity of the treatment so that a good result is always achieved in the shortest possible time.
- the sensor is protected behind the inlet, if necessary behind the inlet filter inside the reactor space.
- the radiation means comprises at least one UV LED, the at least one activatable catalyst mat comprising titanium dioxide as the catalyst material or consisting of titanium dioxide.
- the catalyst mat preferably comprises a carrier layer, for example a woven fabric, gauze, fiber fleece or an open-pore foam, which is coated on one or both sides with the catalyst material. This ensures durability and catalytic activity throughout the life of the laundry treatment cabinet.
- a plurality of catalyst mats are mounted at a distance from one another in the reactor space. This provides a large reactive area for the catalyst material with compact dimensions of the reactor space.
- the catalyst mats are attached lengthwise in the direction of flow in the reactor chamber, so that the air to be treated can flow through the gaps between the spaced catalyst mats and through the gap between the catalyst mat and the respective adjoining wall of the reactor chamber.
- the mat or mats is or are pleated, whereby the active or activatable surface of each mat is enlarged.
- the reactor space is arcuate, semicircular or dome-shaped, with the apex being at the top.
- the catalyst mats are curved, semicircular or dome-shaped.
- the radiation means is designed in such a way that it can be activated with different power levels, with the control device being set up to switch the corresponding power to the radiation means.
- control device is set up to activate the blower and the radiation means for a period of 10% to 80%, based on the total treatment time for the laundry. This protects the air treatment device and ensures a long service life because no process air is conveyed through the reactor space when the air treatment device is inactive.
- control device is set up to activate the blower and radiation means depending on the type of laundry or type of care to be treated, preferably with regard to the duration and/or intensity.

- Fig. 3 an example of a sketched, sectional side view of
- Fig. 4, 7 Schematic of a device for air treatment in different
- Fig. 5, 6 the catalyst mat of the device in different versions.
- Fig. 1 shows a laundry treatment cabinet 1 with the door 5 open in the viewing direction at an angle from above, in which the interior 3 is visible.
- the laundry treatment cabinet 1 is a drying cabinet, comprising a housing 2 in whose interior 3 there are means 31 (FIG. 2) for hanging laundry or clothes hangers 91 .
- the laundry treatment cabinet 1 Inside the housing 2 , the laundry treatment cabinet 1 includes a heat pump unit 8 for providing and conveying the process air, which is admitted into the interior 3 through the inlet opening 81 and conveyed out of the interior 3 to the unit 8 through the outlet opening 82 .
- the unit 8 is arranged in the lower area 33 of the housing 2 in this example.
- the front side of the door 5 is designed to be opaque in this illustration, but it can be designed to be transparent so that it is possible to look into the closed position.
- the laundry treatment cabinet 1 also includes a device 40 for treating the air in the interior 3 and a control device 18, which preferably includes a microcontroller uC with an associated memory MEM, in order to switch the cooling unit 8 and the device 40 for air treatment according to the program stored in the memory MEM control or to activate and deactivate (FIG. 4).
- FIG. 2 shows the laundry treatment cabinet 1 with the door 5 open in the viewing direction obliquely from below, in which the interior 3 is visible.
- the device 40 for treating the air can be seen in the upper area of the housing 2 above the interior space 3 .
- the air inlet 42 for the device 40 is located at the rear on the upper side 32 of the interior space 3, through which the air F to be treated is sucked out of the interior space 3.
- the air outlet 41 is located in the center area on the top 32 of the interior 3, through which the treated air F is blown out of the device 40 into the interior 3.
- FIG. 3 shows the laundry treatment cabinet 1 in a schematic sectional view with the door 5 closed during operation.
- the heat pump unit 8 for generating the process air P is located in the bottom area of the housing 2.
- the unit 8 comprises a heat pump circuit with a cooling heat exchanger 86 (evaporator), a heating heat exchanger 84 (condenser) and a compressor 85 to pass through the refrigerant contained in the heat pump circuit promote the individual components.
- the process air blower 83 is used to generate the air flow of the process air P, which has passed through the outlet 82 to the cooling heat exchanger 86 and is dehumidified there. The dry, cool air then reaches the heating heat exchanger 84, which it leaves again heated.
- the process air fan 83 is located further downstream and conveys the now dried and heated process air through the inlet 81 into the interior 3 . It can also be seen that the inlet 81 is arranged close to the rear wall of the interior space 3 .
- the outlet 82 is remote from the inlet and located close to the door 5 . An air flow P that reaches the entire interior 3 is thus generated.
- FIG. 3 also shows, by way of example, that the laundry treatment cabinet 1 includes a steam generator 88 . This can also be activated and deactivated by means of the control device 18 in order to supply steam to the interior space 3 or the process air P.
- a steam generator 88 This can also be activated and deactivated by means of the control device 18 in order to supply steam to the interior space 3 or the process air P.
- the device 40 for air treatment is arranged in the upper area of the housing 2 above the interior space 3 . This includes
- At least one activatable catalyst mat 62 which is arranged in the reactor space 50 and can be activated by means of radiation, preferably UV radiation;
- a filter 43 on the inlet side 42 serves to prevent dust and fluff from entering the reactor space 50 .
- the filter 43 can be used optionally and comprises a fleece material, activated carbon or fabric material, preferably a combination of the components mentioned.
- the device 40 for air treatment is shown in a sketched detailed representation. Inside the housing 44 a channel 50 is formed as a reactor chamber, which extends from the air inlet 42 to the air outlet 41 .
- the catalyst mats 62 are arranged within the channel 50 .
- the blower 51 is driven by the blower motor 53 and is used to generate an air flow F and thereby to draw in the air F through the inlet opening 42 into the channel 50 and to guide it along the catalyst mats 62 and along or through the catalyst mats 62 and promote from the air outlet 41 from the channel 50 out again.
- the cleaned air F blown out is then conveyed back into the interior 3 (FIG. 3) of the storage cupboard 1 .
- Radiation means 64 are also installed in the channel 50 or reactor space, which are placed in such a way that they can irradiate the activatable filter layer of the mats 62 when they are switched on or activated by the control device 18 .
- the beams 66 fan out conically so that they reach an area, if possible the entire area, of the mats 62 that can be activated.
- the filter layer preferably comprises a material which causes ionization of the contaminated air F by means of UV radiation and as a result, for example, odor-forming molecules are correspondingly converted.
- the mat 62 acts as a catalyst.
- two radiation means 64 preferably UV LEDs, are used, so that both light cones 66 together irradiate the entire surface of the mats 62 with almost uniform intensity.
- the catalyst material located in the mat 62 is activated by means of the UV radiation, in that it forms free radicals which oxidatively decompose odor-forming molecules.
- the control device 18 with the microcontroller uC and the associated memory MEM for programs and parameters controls the power of the fan 51 or the fan motor 53 and the radiation means 64.
- the control device 18 is also connected to the operating device 19 so that user inputs regarding the intensity of the Air cleaning can reach the controller 18 as a parameter.
- the blower 51 is designed as an axial fan in the example outlined; other types of fan, such as radial fans, can also be used if the housing 44 with the channel 50 formed therefrom is designed accordingly.
- the device can be equipped with a sensor 68 for detecting the air quality, a VOC (Volatile Organic Compounds) sensor, with which odors can be detected.
- VOC Volatile Organic Compounds
- the sensor is connected to the control device 18 so that it can set the duration of the treatment and/or the intensity of the treatment depending on the air quality recorded, so that a good result is always achieved in the shortest possible time.
- the sensor 68 is protected behind the inlet filter 43 inside the reactor space 50 .
- the radiation means 64 are flat and attached to the inside of the housing 44, so that an at least almost uniform radiation of the mats 62 is ensured.
- the mats 62 are designed as flat plates.
- the mats 62 can preferably be designed to be partially translucent so that the mats 62 lying on the inside can also be reached by the activation light 66 .
- the radiation means 64 are flat and attached to the inside of the housing 44, so that an at least almost uniform radiation of the mats 62 is ensured.
- the mats 62 are pleated, which increases the surface area of the individual mats 62 along which the air F to be treated can flow or at least partially flow through.
- the mats 62 can preferably be designed to be partially translucent so that the mats 62 lying on the inside can also be reached by the activation light 66 .
- the channel or reactor space 50 is arcuate or hemispherical, with the catalyst mat 62 being arcuate in shape corresponding to the shape of the reactor space 50 .
- the radiating means 64 is arranged centrally at the focal point of the arc and is designed to emit the light 66 in a fan shape in the direction of the arc-shaped mat 62 . In this example there is only one catalyst mat 62 in the reactor space 50.
