Description

Air purification system for purifying indoor air and operation method thereof

Technical Field

The invention relates to an air purification system for purifying indoor air, comprising: a first module and at least one other module; communication means for wireless communication between these modules and a control unit for controlling these modules. The invention also relates to a method for controlling an air cleaning system for cleaning indoor air, wherein at least two modules are operated, and wherein a blower unit and a filter unit are operated in one module.

Background

Air purifiers are increasingly used in homes and smaller residential or work areas to purify indoor air continuously or at specific time intervals. Air purification is necessary and desirable, for example in areas with a high pollutant load of the external environment or in spaces where there is a partial presence of room air with pollutants, for example by smokers.

In the known air cleaners, functional units such as, for example, operating components, status display devices, sensor means, power or control electronics with a power supply, filter technology and blower structure are integrated in one device. In some modules in the form of remote control, only the control part is spatially separated from the master device.

Here, all or a part of the manipulation part of the air purifier may be provided in a remote manipulation manner. In known air purifiers with remote manipulation, the communication is performed in a wireless and unidirectional manner. Accordingly, the state display of the remote manipulation only relates to the function of the remote manipulation, but does not explain the state of the air purifier.

The known air cleaners have integrated sensor units, i.e. sensor means for air quality determination, such as dust or particle sensors, which are thereby locally connected to the air cleaner. The determination of the air mass is therefore carried out in dispersed form. Since the air quality is not detected at the usual resting place of the user (for example at a desk, a table, a bedside table or above a baby bed) but at the location of the air purifier.

In addition, known air purifiers have only a filter-blower combination. Each filter-blower combination is designed for a specific space size and therefore cannot be expanded. Lower operating noise and higher purification efficiency require large-area filters with the target precondition of lower energy consumption. The integration of large-area filters in turn leads to a large size of the known purifier with a corresponding purification efficiency. It is common for the dimensions of the purifier to be 400mm by 300mm by 600 mm. Due to their large size, air purifiers are often placed not centrally (i.e., on a desk or centrally placed in a room), but rather discretely against a wall or in a corner of a room.

In addition, the limitation to a particular filter-blower combination is accompanied by two disadvantages. First, local restrictions occur by preferably purifying only the immediate surroundings of the air purifier, especially under adverse placement conditions (such as under a desk or in an indoor corner). Therefore, the air circulation is locally conspicuously prominent. In addition, the decentralized placement of air cleaners, in particular in the corners of rooms or under desks, is disadvantageous for air circulation and thus for air cleaning, since, under correspondingly unfavorable placement conditions, air cleaners, instead of sucking and cleaning further contaminated air from remote spatial areas, process their own clean air increasingly during operation.

Second, the purification efficiency cannot be expanded with respect to the room. Since it is assumed that no higher purification level with a higher air flow rate can be selected above the upper limit for the noise generation, there is only the option in a larger space to operate another air purifier in order to achieve a purification power matched to the room. On the other hand, in a small space, the size of the air purifier adjusted to the minimum purification power may still be excessively large, thereby possibly causing noise pollution, ventilation, and energy loss to be excessively large.

In addition, in the known apparatus, different status information of the air purifier, such as an operation mode, air quality, air humidity, and filter replacement status, is displayed only on the air purifier. Thus, the status display in the form of a display and/or LEDs is integrated in the air purifier and thereby locally connected to the air purifier. In the precondition of a decentralized arrangement of the air purifiers, the status display is usually arranged at a distance from the user and accordingly cannot be perceived at all or not at all by the user. However, the presence of an air purifier and the awareness of its working power and its function are important aspects, especially since "clean air" as a product of an air purifier is difficult or completely imperceptible to a user.

In addition, the known air purifier has one or more of the following units. An additional humidification unit for humidifying the purified air, means for adding aromatic substances to the purified air, an ionization unit (for example a UV light source if necessary in combination with a TiO2 catalyst or a source for generating a non-thermodynamic plasma) for reducing pathogens in the purified air and thus for disinfection or even for sterilization. Air purifiers with integrated modules for filter disinfection also exist.

In the known air cleaners, it is disadvantageous that the so-called additional functionality is integrated in one device as a multifunctional device and thus divides the available housing volume into different functional blocks and thus only a compromise solution is achieved. For example, the filtering surface of the air filter in the case of an air purifier-air humidifier multifunction device increases the expense of the tank solvent or necessarily the housing volume itself, which makes the resulting air purifier heavier and more difficult to transport.

In addition, in the air purifier as the multifunction device, it is disadvantageous that a customer must purchase various functions integrated in the multifunction device although it desires or requires only a part of the functions. In addition, in the case of air purifiers as multifunctional devices, it is disadvantageous that these individual functions cannot be individually changed. For example, in order to improve the function for air humidification, the customer must use a second multi-function device, which is completely undesirable for other functions, such as fragrance generation.

Disclosure of Invention

The object of the present invention is therefore to specify an air cleaning system for cleaning room air and a method for operating an air cleaning system, which at least partially eliminate the above-mentioned disadvantages.

According to the invention, the above object is achieved by an air cleaning system, in which each module has a communication device and at least one functional unit, wherein the at least one functional unit of each module is selected from the following group: a sensor unit, a blower unit, a filter unit, a system status display unit, an air sanitation unit (Luft-Hygiene-Einheit), an air conditioning unit (Klimatinib unrestrained seinheit), a fragrance release unit (Duftstreeneinheit), a fresh air unit (Frishluftenheit) or a sound emission unit (Schallerzeugseinheit), and wherein at least one of these modules has at least one blower unit and at least one filter unit.

According to the invention, it is possible to provide that the functionality, apart from a purely remote actuation, can be distributed to at least two modules, wherein at least one selected functional unit is present in each module and the modules can be combined in any desired manner. The only requirement is that there must always be at least one blower unit and at least one filter unit in at least one module to ensure the ability of the system to function as an air purification system. The air purification system according to the invention thus comprises at least two modules with independent functionality, thereby achieving improved flexibility and scalability of the air purification system.

By means of the air cleaning system described above, a system is achieved which is highly modular and scalable and can be adapted to the needs of the user and to the specific spatial conditions. By the possibility of modular optimization in the form of individual functional units, a higher effective power is achieved than in a multifunction device.

The air cleaning system according to the invention is preferably arranged in a separate space and adapted thereto. The air cleaning system can thus be formed separately and adapted to the particular spatial conditions.

As is also common in the prior art, these modules have at least in part handling means. Buttons, switches, touch panels, touch displays, capacitive touch elements, gesture recognition by means of a camera or voice control can be used as operating elements.

As sensor unit, sensors can be used which measure one or more parameters of the ambient air. Such as dust or particle sensors, VOC sensors for detecting hydrocarbons, CO₂Sensor, SO_XSensor, NO_xA sensor or an air humidity sensor may be used as the sensor.

Known axial or radial ventilation devices can be used as blower units. Other techniques for generating air flow may also be used.

The filter material used in the air purification system may for example consist of materials known from the filtration art: a filter nonwoven, an electrostatic filter, activated carbon, a different catalyst, a UV-catalyst, a HEPA-filter for allergen reduction, a fine dust filter or a washable textile filter. The filter unit can be designed here as a normal filter unit (normal in terms of size and material) or as an air filter implementation module with a greater purification efficiency than in conventional filter materials. The energy efficiency in the air filter module is therefore greater than in the base module. The filter unit can also be designed as a special harmful substance filter unit (with special filter material for filtering a specific harmful substance). Designs as kitchen filter units are also possible.

The system status display unit preferably has means for displaying the status of the air purification system, in particular for displaying the status of all modules. The operating mode and, if necessary, also the detection result of the sensor unit can thus be displayed to the user in a simple and comfortable manner, for example on a table, a desk or on a bed, and the module does not have to have a combination of a blower unit and a filter unit. The system status display unit may have LEDs, a display or a loudspeaker for status display.

In addition, the wireless communication takes place mainly bidirectionally, so that data exchange for transmitting measurement and control information takes place between the modules in both directions. In thatIn special cases, only one-way communication between these modules may be necessary, so that the bidirectional feature should not be understood in a limiting manner. The wireless communication may be via optical means (e.g. infrared light source and infrared receiver, especially LED' S) or via any radio communication (e.g. wireless LAN (WiFi)) or

) The process is carried out.

Furthermore, at least one module of the air purification system is connected via an interface to an external communication network, i.e. an intranet or the internet. Thus, external control of the air purification system is possible.

By spatially separating and combining the functional units of the air cleaning system, in particular by spatially separating the sensor unit and the system status display unit from the combination of blower unit and filter unit, the location of the air cleaning can be separated from the location of the air quality measurement by means of the sensor unit. The sensor unit can thus be placed in the vicinity of the user, so that the air quality in the immediate vicinity of the user can be determined.

In addition, in another embodiment of the present invention, the system status display unit is placed in the vicinity of the user so that the user is informed of the air purifier or the entire air purification system to a greater extent.

In addition, design freedom can be created, since the housing with only the combination of blower unit and filter unit can be formed in a completely different manner than if the system status display unit and the sensor unit had to be arranged together in the same housing.

By doubling or quadrupling individual or all functional blocks, in particular the combination of blower unit and filter unit, in individual modules, the cleaning power can be expanded arbitrarily with a constant air flow per combination of blower unit and filter unit. In particular, the circulation of the indoor air flow can be fluidically formed or guided and thus adapted to the given indoor conditions.

Furthermore, the air purification system can be designed differently by doubling or quadrupling the individual or all functional units in a single module. In particular, the use of at least two sensor units allows an improved air quality determination, since a plurality of measuring stations can be arranged in the space. In addition, the doubling or the quadrupling of the individual modules by individual or all functional units, in particular the system status display unit and the operating unit, increases the range of the air purification system and thus the comfort of the user.

In a particularly preferred manner, a control device of the first module is provided for controlling at least one further module, in particular for controlling all further modules. One module thus forms the base module and at least one other module can then become the associated module or the planetary module. In this case, the first module as a base module preferably also has a system status display unit.

A first preferred embodiment of the air cleaning system is that the first module has a sensor unit and at least one other module has a blower unit and a filter unit. In this embodiment, the air purification system is divided into at least two modules, wherein the first module is formed, for example, as a desk module and the sensor unit measures the air quality in the immediate surroundings of the desk. At least one other module has instead a filter-blower combination and can be placed indoors, shortly after the table.

The first module can transmit the measurement data to the other modules via a wireless two-way communication device, so that the air purification system can be controlled here by at least one of the other modules as a function of the measurement data. The data of the current adjustment of the air purification system can then be transmitted via the communication device to the first module and can be displayed there in a user-oriented manner.

Alternatively, the first module itself can analyze the measurement data and the control unit present in the first module takes care of the control of the air purification system by transmitting the control data to at least one other module via the communication means. The currently adjusted parameters of the air purification system may then be displayed directly on the system status display unit on the first module.

Another preferred embodiment of the air cleaning system is that the first module has a sensor unit and a blower unit, and at least one further module has a blower unit and a filter unit. The same functionality as described above is thus obtained. The blowing in the first module additionally achieves a targeted guidance of ambient air to the sensor unit, so that the measurement accuracy of the sensor unit can be increased.

In addition, the respective other module can also have a sensor unit, so that the measurement data detection of the first module is improved by measuring and analyzing the air quality at other points in the at least one room. The measurement data of the sensor units of the other modules are then likewise transmitted to the first module via the bidirectional communication device.

In a further preferred embodiment of the air cleaning system, the first module has a sensor unit, a blower unit and a filter unit, and at least one further module has a blower unit and a filter unit. At least two modules are thus identical air purifiers. In practice, the first module is formed not only as a desk module but also as a floor module and may be placed, for example, near a desk or a place where it can sit.

A further preferred embodiment of the preferred air cleaning system consists in that the first module and the at least one further module each have a sensor unit, a system status display unit, a blower unit and a filter unit. At least two modules are thus formed in an identical manner and are connected by a bidirectional communication device for common data exchange. It is thus possible to build a network of two or more equivalent air purifiers to one air purification system, which can be used in particular in larger spaces.

In addition, the air cleaning system can be designed such that the first module has a blower unit and a filter unit and, if appropriate, a sensor unit, and at least one further module, preferably a plurality of further modules, has a blower unit. Thus, the first module, which is the base module, is formed as a stand-alone air purifier, wherein at least one other module is formed as a pure air fan, i.e. an air circulation unit. The other modules may therefore also be referred to as airflow planet modules. At least one other module can thus circulate the air in the room more strongly and improve the cleaning action of the first module. This arrangement is also particularly suitable for larger spaces. Since the at least one further module only has to accept data from the first module (base module), it is sufficient in such an embodiment when the communication device enables unidirectional communication from the first module to each of the at least one further module. However, the bidirectional communication may also be advantageous here if the current adjustment of each of the at least one further module is transmitted to the first module. This enables a better control of the components of the air purification system.

A further preferred embodiment of the air cleaning system described above is that the first module has a blower unit and a filter unit and optionally a sensor unit, and at least one further module has an air cleaning unit, an air conditioning unit, a scent release unit, a fresh air unit or a sound unit. Other components are therefore built into the air purification system described above, which enable the power spectrum of the system to be varied. These components can be specifically fitted according to the requirements for the air purification system.

In the air sanitation unit, germs and viruses in the air flowing through can be removed. For this purpose, a non-thermodynamic plasma with a downstream catalyst structure (for example composed of activated carbon or manganese dioxide) is preferably used. Alternatively or additionally, one or more UV light sources may also be used. The UV light source may additionally be supplemented with a photocatalyst, such as TiO₂. Ozone may also be used.

The flow rate in the air sanitation unit may be set smaller than the air purifier unit consisting of the blower unit and the filter unit to ensure that the germ-killing mechanism acts on the circulating germs and viruses for as long an action time as possible.

The air conditioning unit should humidify and/or dehumidify the air circulating therethrough. Alternatively or additionally, the air conditioning unit may cool or heat air circulating therethrough. The functions of humidification/dehumidification or cooling/heating may even be implemented in separate other components.

The above-described fragrance releasing unit may release a fragrant substance into the ambient air, for example by means of a separately generated air flow. The release of the fragrant substance may be based on, for example, ultrasonic atomization.

The fresh air unit can additionally be made oxygen-poor and rich in CO₂Room air with rich oxygen and lack of CO₂Is exchanged. This is preferably achieved by a window-mounted module which takes the exchange of room air with the outside air. The switching preference is regulated by a first module with a corresponding control for the CO₂And oxygen, while the fresh air module represents one of the other modules. The fresh air unit may alternatively have a refillable oxygen tank and CO₂Absorber and thereby realizing the effect of being rich in oxygen and lacking in CO₂Without being mounted on a window or on an external wall, i.e. without having to exchange the interior air with the outside air.

The sound generating unit is adapted to reduce the ambient noise by anti-noise. For this purpose, an arrangement of a microphone, a booster and a loudspeaker is provided, in order to generate noise immunity.

The above-mentioned or additional filter units can be formed as special harmful substance filter units and filter one or more gases harmful to health. The filter unit can filter formaldehyde from the room air. The flow rate of the air through the special harmful substance filter unit is preferably selected to be smaller than the flow rate in the basic filter unit, so that as long a reaction time as possible between the harmful gas (formaldehyde, toluene … …) and the harmful substance adsorption medium (for example, activated carbon) is ensured.

The filter unit can additionally also be formed as a kitchen filter unit and have a filter technology specifically directed to filtering and eliminating grease, kitchen odours and cooking odours contained in the indoor air.

According to the invention, the above object is also achieved by a method for controlling an air purification system for purifying room air, wherein at least two modules are operated, wherein a blower unit and a filter unit are operated in one module, wherein a functional unit selected from the following group is operated in at least one other module: a sensor unit, a blower unit, a filter unit, a system status display unit, an air sanitation unit, an air conditioning unit, a scent release unit, a fresh air unit or a sound unit, and wherein wireless communication between these modules is at least temporarily operated in order to exercise control over these modules.

The method according to the invention and the design of the method implemented below have advantages similar to those already described for the system described above.

The method is preferably carried out in such a way that the first module carries out the control of at least one further module.

Furthermore, a sensor unit can be operated by the first module and a blower unit and a filter unit can be operated by a further module.

Furthermore, a blower unit and a sensor unit can be operated by the first module and a blower unit and a filter unit can be operated by the other module.

In a preferred manner, a blower unit, a filter unit and a sensor unit are operated by a first module, and a blower unit and a filter unit are operated by a further module.

In addition, a system state display unit, a blower unit, a filter unit and a sensor unit can each be operated by the first module and by a further module.

It is further preferred that a blower unit and a filter unit are operated by the first module and, if necessary, a sensor unit and that a blower unit is operated by at least one further module.

Finally, a blower unit and a filter unit and, if appropriate, a sensor unit can be operated by the first module, and an air sanitation unit, an air conditioning unit, a scent release unit, a fresh air unit or a sound unit can be operated by at least one further module.

Detailed Description

In the following description of different embodiments according to the invention, identical components are provided with the same reference numerals, even though these components may differ in their manner of operation, size or shape in different embodiments.

Fig. 1 shows a first embodiment of an air purification system 2 for purifying indoor air. The system has a first module 4 and a further module 6 which implement communication means 8 and 10 for wireless two-way communication between the modules 4 and 6. In addition,

control units

12 and 14 are provided for controlling modules 4 and 6; and operating

elements

16 and 18 for switching the modules 4 and 6 on and off and, if necessary, for inputting control commands. The

control units

12 and 14 are currently provided with or connected to a power source.

According to fig. 1, each module 4 and 6 has at least one functional unit. The first module 4 has a sensor unit 20 as a functional unit, while the other modules 6 have a blower unit 22 and a filter unit 24. The other modules 6 thus represent actual air purifiers.

The first module 4 therefore detects the quality of the room air in the region of its location and analyzes the sensor signals electronically by means of the control unit 12. The first module 4 can control the further modules 6 on the basis of the basic adjustment by the operating element 16 or, if necessary, on the basis of the measurement results by the sensor unit 20 via a wireless communication path (shown in fig. 1 by the double arrow a between the two communication devices 8 and 10).

The further module 6 in turn transmits the current operating state and, if necessary, further parameters to the first module 4 via the wireless communication path a.

If, after evaluation of the measurement signals of the sensor unit 20, the control device 12 of the first module 4 determines that the room air is not good enough (in particular because the oxygen content is too low, CO₂Too high or the specific gravity of other substances in the indoor air is not good enough), the control unit 12 generates a control signal for increasing the purification power of the air purification system 2. In addition, the control unit 12 checks, by analyzing the data transmitted by the other modules 6 to the first module 4, which operating state of the other modules 6 is present. The blower unit 22 and the filter unit 24 provided in the other module 6 can be adjusted for enhanced cleaning of the room air if the operating state of the other module 6 allows a change in the cleaning power. For this purpose, the control unit 12 of the first module 4 sends control commands to the control units 14 of the other modules 6 via the wireless communication path a. The first module 4 may therefore also be referred to as a base module.

If, at another point in time, the control unit 12 determines a sufficiently good air quality by means of the measurement signals of the sensor unit 20 in the first module 4, the further module 6 can be controlled by the first module 4 in such a way that a normal intensive air cleaning takes place or the air cleaning is completely stopped.

Thus, in the above described embodiment, the control unit 12 of the first module 4 is used to control the other modules 6.

As can additionally also be seen from fig. 1, the first module 4 has a system status display unit 26 which has means for displaying the status of the air cleaning system 2 and in particular the status of the two modules 4 and 6. The status of the entire air purification system 2 can thus be read at the first module 4. The means for displaying can be formed here in the form of light-emitting diodes or in the form of a display. Here, the display can also be formed preferably as a touch display and thus also at least partially implement the actuating element 16.

Fig. 2 now shows the first embodiment of the air purification system according to the invention, which is schematically shown in fig. 1, in actual use. The first module 4 is formed as a desktop device and is arranged on a desk in the indoor environment shown in fig. 2. The other modules 6 are formed as described above as air cleaning devices with a blower unit 22 and a filter unit 24.

By laying on a table, the first module 4 can analyze the room air at the location where the person is actually located by means of the sensor unit 20 arranged therein, while the other modules 6 are positioned at the corners of the room and are thus less susceptible to interference. An air inlet 28 and an air outlet 30 for the generated air flow are provided on the housing of the other module 6.

Fig. 3 shows a second exemplary embodiment of an air purification system 2 according to the invention, wherein like reference numerals designate like components as have been described in detail with reference to fig. 1.

In contrast to the first exemplary embodiment, the first module 4 has a blower unit 32 which generates an air flow through the sensor unit 20 via a suction opening 34 and an air outlet 36. Thereby further improving the reliability of the quality detection of the ambient air.

Another difference with respect to the first exemplary embodiment is that the other modules 6 also have a sensor unit 38 and a system status display unit 40. It is thus also possible to detect the quality of the room air at the location of the other modules 6 and to read the real-time adjustment of the air cleaning system at the same time. Thereby improving the overall system operation.

Fig. 4 shows a third exemplary embodiment of an air purification system 2 according to the invention, wherein the same reference numerals denote the same components as have been described in detail with reference to fig. 1 and 3.

The third embodiment of the air cleaning system 2 differs from the embodiment shown in fig. 3 in that the first module 4 has, in addition to the sensor unit 20, a blower unit 42 and a filter unit 44, which generate an air flow through a suction opening 46 and an air outlet 48. The other modules 6 are formed in the same manner as in the second embodiment.

The first module thus represents not only the basic module with the measuring and control functions as in the first two exemplary embodiments, but also an air cleaning function, similarly to the other modules 6. The air cleaning system therefore has two air cleaners which are equivalent and which are controlled by means of the control unit 12 of the first module 4 in the manner described above using the communication path a and are coordinated with one another with regard to their operating state.

Fig. 5 shows a fourth exemplary embodiment of an air cleaning system 2 according to the invention, wherein like reference numerals designate like parts as already described in detail with reference to fig. 1, 3 and 4.

The fourth exemplary embodiment of the air cleaning system 2 has first of all a first module 4 as shown and described with reference to fig. 4. In addition, the air purification system 2 has two

other modules

6a and 6b each formed as an air purifier.

For this purpose, the two

other modules

6a and 6b have respective communication devices 10a and 10b, which are connected wirelessly to the communication device 8 of the first module, as is schematically shown in dashed lines. In addition,

control units

14a and 14b are provided which ensure the operation of the two

other modules

6a and 6 b. Finally, the two

other modules

6a and 6b also have

blower units

22a and 22b and filter units 24a and 24 b.

As mentioned above, the control of the air cleaning system 2 is in turn taken care of by the first module 4. The control signals for the adjustment of the

further modules

6a and 6b are transmitted via a wireless communication path (which is currently transmitted only in one direction) in order to transmit control commands to the two

further modules

6a and 6b, since the transmission of the operating state of the

further modules

6a and 6b to the first module 4 is not permitted. However, the communication path may also be formed bidirectional as described above.

Therefore, the air purification system 2 of the fourth embodiment is composed of three

modules

4, 6a, and 6b formed as air purifiers in total, which can be dispersedly arranged indoors.

Fig. 6 shows a similar design in a practical application. The fifth embodiment of the air cleaning system 2 according to the invention shown here has a first module 4 corresponding to the above-described embodiment, without the individual components being explicitly identified in fig. 6. The first module 4 therefore represents not only a module for controlling the air purification system, but also an air purifier. Two further modules 6c and 6d are provided, each formed as a blower unit in the form of a fan 50 (which can also be referred to as a ventilation unit).

Thus, during operation of the air purification system 2 according to fig. 6, air purification by the first module 4 is assisted by the operation of the other modules 6c and 6d, thereby enhancing the air flow in the room. The fan 50 circulates air, thereby increasing the specific gravity of the indoor air that can be purified by the first module 4. The air cleaning system 2 is therefore also particularly suitable for use in large spaces.

Fig. 7 shows a fifth exemplary embodiment of an air cleaning system 2, wherein the first module 4 is formed as in the first exemplary embodiment according to fig. 1 and 2, i.e. with a blower unit 42 and a filter unit 44 and a sensor unit 20, as well as the further components described above. The air cleaning system 2 additionally has two

further modules

6e and 6f, which can also be referred to as special modules. The

other modules

6e and 6f can in principle be formed as air sanitation units, air conditioning units, scent release units, fresh air units or sound units. In addition, at least one of the other modules can have a filter unit, which is formed as a special harmful substance filter unit or as a kitchen filter unit. The characteristics of these different units have been explained above.

The air cleaning system 2 of the fifth exemplary embodiment therefore comprises, in addition to the actual air cleaning by the first module 4, further properties which are advantageous for the user of the air cleaning system 2 and which are achieved by the

further modules

6e and 6 f. In this case, for example, the number of further modules is selected to be two, more than two further modules being connectable in principle to the first module by wireless communication.
