This application claims priority to German Patent Application Serial No. 10 2018 101 698.0, which was filed Jan. 25, 2018, and is incorporated herein by reference in its entirety.

TECHNICAL FIELD

Various embodiments relate generally to an apparatus for growing plants, and relate e.g. to a climate control device of the apparatus for growing plants and to a method for growing plants.

BACKGROUND

In the field of the provision of fresh products such as for example herbs, salad, fruit and vegetables, consumer demands have grown to an increasing extent in recent years. In particular since the denunciation of abuses in the husbandry of animals for slaughter, and the increasing prevalence of vegetarian or vegan foods, the awareness of many consumers of fresh products, and their demand for these, has increased.

These products have hitherto for the most part been produced either on fields or in greenhouses of large industrial operations and brought to the consumers by being sold in supermarkets. To a lesser extent, the consumers also obtain a supply directly from the producer at weekly markets and from direct selling on farms, wherein these distribution channels are available only to a relatively small part of the population owing to the restricted time availability or the required spatial proximity to the producer.

With the increased awareness of large parts in particular of the urban population with regard to their own health, there is, specifically in this case, an increasingly growing demand for products from controlled cultivation, and even the desire for personal control and meaningful engagement in the cultivation of one's own, correspondingly fresh products.

However, only a very small part of the urban population has access to a garden or corresponding facilities in which, for example, they could set up their own small greenhouses in order to cultivate fresh products. Also, the urban environment seldom offers the possibility of handling planting boxes and pots without relatively great organizational effort, let alone providing the plants cultivated therein firstly with the required protection against weather influences and secondly with adequate sunlight in order to promote the desired growth of the plants.

Furthermore, specifically the urban population commonly has a daily routine involving working away from home and often long traveling distances to and from the workplace, such that there is no desire, aside from everything else, to also tend to the growth of plants, to monitor this growth, and to adapt the care of these plants to the respective growth phase.

Owing to all these difficulties, many people who would in fact gladly benefit from cultivating their own plants and harvesting their own products are put off by the effort that the cultivation of these plants entails. They are put off even more by the feeling that there is a very low likelihood that, after all the effort, fresh ingredients from one's own cultivation will in fact be worthwhile, because, in hectic urban everyday life, it is not possible to ensure care of the plants which is sufficiently optimal that it leads to good results.

In terms of the informed consumer who intentionally wishes to eat healthily and at the same time is intent on achieving sustainability but has neither the space nor the time to cultivate plants in the conventional manner, it is thus desirable to create a means with which even small consumers, such as for example the typical modern single urban resident, can independently supply themselves with fresh food ingredients to the desired extent.

In the context of these demands, an apparatus has recently been proposed with the aid of which even individual consumers can, on a small scale adapted to common kitchen sizes, grow herbs, salads, vegetables, mushrooms or fruit.

A particular problem in the case of such growth of plants is that, aside from the supply of water and nutrients, they require further ambient conditions which benefit plant growth, wherein these ambient conditions vary from one plant type to another and over the course of the germination and growth of the plants. Here, the temperature and humidity of the surrounding air must be constantly monitored and regulated. Here, substantial automation of the ambient conditions in the apparatus for growing plants is desirable.

As illustrated inFIG. 3, the apparatus for growing plants300includes, in various embodiments, a cabinet-like housing310, which in this case is illustrated from a semi-frontal perspective. For the sake of simplicity, a door of the housing310has been omitted in this illustration.

The housing310may include a base314in which, for example, a water tank (not illustrated) of an irrigation apparatus20(not illustrated, seeFIG. 1) may be accommodated. A temperature sensor318for determining an ambient temperature may be provided on a side wall303of the housing310. For example, the temperature sensor may be arranged on an outer side of the side wall303of the housing310.

The housing310includes an accommodating space312which may be configured for accommodating at least one drawer-like growing unit (not illustrated, seeFIGS. 2A-2D). Here, each of the growing units may be configured such that at least one seed mat may respectively be placed thereon. In other words, the accommodating space may be configured for accommodating one or more seed mats.

The apparatus for growing plants may furthermore include a controller60(not illustrated, seeFIG. 1). Furthermore, the apparatus may include the irrigation apparatus20(not illustrated, seeFIG. 1), at least one illumination apparatus30(not illustrated, seeFIG. 1) and a climate control device40(not illustrated, seeFIG. 1). The controller may be configured to actuate the illumination apparatus, the climate control device and the irrigation apparatus by means of a program controller.

As may be seen fromFIG. 3, side walls303of the housing310may include guide rails304for accommodating the growing units (not illustrated). For example, one or more guide rails304may be arranged on each of the side walls303such that one or more growing units (not illustrated) may be arranged one above the other in the manner of storeys in the accommodating space312. For example, an apparatus for growing plants300may include a lower storey305aand an upper storey305bin the accommodating space312. In other words, one growing unit (not illustrated) may, for example, respectively be introduced by means of the first guide rails304aand/or the second guide rails304binto the accommodating space312such that a lower storey305aand/or an upper storey305bis formed.

The side walls303of the housing310may furthermore include various sensors of the climate control device. For example, in the side walls303, there may be arranged at least one air humidity sensor315for determining the air humidity in the accommodating space312, at least one temperature sensor316for determining an air temperature in the accommodating space312, and a CO2sensor317for determining a CO2content of the air in the accommodating space312. For example, the lower storey305amay include a first air humidity sensor315aand a first temperature sensor316a, and the upper storey305bmay include a second air humidity sensor315band a second temperature sensor316b. The upper storey305bmay furthermore include the CO2sensor317as illustrated inFIG. 3. Alternatively, the CO2sensor317may also be arranged (not illustrated) in the lower storey305a.

Alternatively, the first air humidity sensor315aand the first temperature sensor316amay be designed, or in other words formed, as a combined air humidity-temperature sensor (not illustrated). Likewise, the second air humidity sensor315band the second temperature sensor316bmay be designed, or in other words formed, as a combined air humidity-temperature sensor (not illustrated). Furthermore, an air humidity sensor, a temperature sensor and the CO2sensor may be designed as a combined air humidity-temperature-CO2sensor (not illustrated).

The controller may in particular be configured to receive measured values determined by the various sensors315,316,317,318, or in other words sensor values determined by the various sensors315,316,317,318. For example, the controller60may be configured to receive, from the air humidity sensors315a,315b, measured values or sensor values for the air humidity determined in the respective storey305a,305b. Likewise, the controller60may be configured to receive, from the temperature sensors316a,316b, measured values or sensor values for the air temperature determined in the respective storey305a,305b. The controller60may also be configured to receive, from the CO2sensor317, measured values or sensor values for the CO2content determined in the accommodating space312. Furthermore, the controller60may be configured to receive measured values or sensor values from the temperature sensor318for determining the ambient temperature.

As already stated above, the controller60may furthermore be configured to control the irrigation apparatus20, the illumination apparatus30and the climate control apparatus40of the apparatus300by means of the program controller. For example, the controller60may be designed to regulate an interior space climate prevailing in the accommodating space312by means of the climate control device40on the basis of the sensor values determined for the air humidity and for the air temperature in the accommodating space312. In various embodiments, the controller60may be designed to regulate a microclimate prevailing in the respective storey305a,305bby means of the climate control device40on the basis of the sensor values determined for the air humidity and for the air temperature of the respective storey305a,305b.

In other words, the controller60may be configured to adjust an air temperature and an air humidity in the accommodating space312on the basis of the sensor values of the sensors315,316. For example, the controller may be configured to adjust a climate in the accommodating space312or in an individual storey305a,305bon the basis of the sensor values determined by the temperature sensors315a,315band the air humidity sensors316a,316b, or in other words on the basis of the determined temperature sensor values and the determined air humidity sensor values.

The controller60may for example be configured to actuate the climate control device40(not illustrated) such that the air temperature is regulated on the basis of the determined temperature sensor values. For this purpose, the climate control device40may for example include a cooling appliance (not illustrated, see for exampleFIG. 4, reference symbol441), wherein the cooling appliance may include a condenser (not illustrated, see for exampleFIG. 4, 442), an evaporator (not illustrated, see for exampleFIG. 4, 444) and a compressor (not illustrated, see for exampleFIG. 4, 446).

In various embodiments, the control device60may be configured to actuate the climate control device40for example such that the air temperature in the accommodating space312is lowered by means of the cooling appliance (not illustrated). Furthermore, the control device60may be configured to increase the air temperature in the accommodating space312for example by means of a heat quantity radiated by the illumination apparatus30(not illustrated, seeFIG. 1).

Furthermore, the control device60may be configured to regulate the air humidity in the accommodating space312by means of the evaporator (not illustrated).

The climate control device40may furthermore include at least one cooling blower (not illustrated) and at least one LED cooling blower (not illustrated). The controller60may be configured to actuate the cooling blower of the climate control device such that the air temperature in the accommodating space is regulated. Furthermore, the controller may be configured to actuate the LED cooling blower of the climate control device such that heat that is radiated by LED modules of the illumination device30is dissipated. The at least one cooling blower and the at least one LED cooling blower will be described in more detail with reference toFIG. 4toFIG. 6C.

The housing310may furthermore include a door sensor319, wherein the door sensor319is configured to determine whether a door (not illustrated, see door16ofFIG. 1) of the apparatus for growing plants300is open or closed. The door sensor319may for example include an IR sensor319. In various embodiments, signals of the door sensor319may be fed to the controller (not illustrated). In other words, the controller may be configured to receive signals of the door sensor319relating to whether the door of the apparatus is open or closed.

In various embodiments, the controller (not illustrated) may be configured to, when the door is open, actuate the irrigation apparatus, the illumination apparatus and the climate control device such that the user can for example handle the seed mats in the accommodating space. For example, in various embodiments, the controller may be configured to, when the door is open, actuate the illumination apparatus such that light with a spectral composition is emitted such that the accommodating space312is illuminated normally for a user (in other words, that light of a spectral composition visible to the user, or in other words again in a spectral composition in the case of which the user can see clearly, is emitted). The controller may furthermore for example be configured to, when the door is open, actuate the irrigation apparatus such that no water is fed to the irrigation troughs. Furthermore, the controller may for example be configured to, when the door is open, actuate the climate control device such that the at least one cooling blower is deactivated.

Furthermore, in various embodiments, the controller (not illustrated) may be configured to, when the door is closed, actuate the irrigation apparatus, the illumination apparatus and the climate control device such that an interior space climate adapted to the respective plants growing in the growing unit, and to the state of said plants, is produced. For example, the controller may be configured to, when the door is closed, actuate the illumination apparatus such that the respective plants growing in the accommodating space are irradiated with specific light of a spectral composition which benefits their growth. Furthermore, the controller may be configured to, when the door is closed, actuate the irrigation apparatus such that the seeds arranged on the seed mats, or the plants which grow from said seeds, are fed with water and nutrients in accordance with their state. Furthermore, the controller may be configured to, when the door is closed, actuate the climate control device such that the at least one cooling blower is activated if this is necessary in order to maintain, in the accommodating space, the interior space climate beneficial to the seeds arranged on the seed mats, or to the plants which grow from said seeds, in accordance with their state.

A method for growing plants and for controlling the climate of the accommodating space312of the apparatus for growing plants will be described with reference toFIG. 8.

For example, the LED modules432a,432bmay include a multiplicity of LEDs, for example three or four LEDs, wherein each of the LEDs respectively includes one color channel. In other words, the LED modules432a,432bmay include LEDs with three or four different color channels. The LED modules432a,432bmay however also include a different number of LEDs, for example fewer than three LEDs or more than four LEDs. Here, each LED module432a,432bmay be configured to be dimmed, or in other words regulated or varied, between 0% and 100%. Alternatively, each of the LEDs may be configured to be dimmed, or in other words regulated or varied, individually between 0% and 100%, for example by means of pulse width modulation (PWM) or by means of the applied voltage.

Each LED module432a,432bmay for example include at least one LED which emits light in the blue range of the spectrum, for example in a range from approximately 430 nm to approximately 490 nm, for example in a range from approximately 440 nm to approximately 475 nm, for example in a range from approximately 450 nm to 460 nm.

Here, the LED modules432a,432bmay however also include another respective number of LEDs of the various wavelengths. Furthermore, other LED modules432with LEDs which emit light of other wavelengths may be provided if this is beneficial to the germination of the seeds introduced into the accommodating space or to the growth of the plants which grow from said seeds.

In various embodiments, the controller may be configured to actuate each of the LED modules432a,432bsuch that an illumination duration (or illumination time period), an illumination intensity and a composition of the illumination spectrum, or in other words a composition of the emitted wavelength ranges, is regulated, or in other words controlled or adjusted or varied.

In various embodiments, for the growing of plants, the apparatus400may be configured such that seed mats (not illustrated) which include seeds (not illustrated) are introduced into the accommodating space412. Alternatively, the seed mats may include already-germinated plants (not illustrated), and the apparatus400may be configured for accommodating the seed mats with the germinated plants in the accommodating space. For this purpose, the mat carriers454a,454bmay be configured such that the seed mats are placed onto the mat carriers454a,454b. The apparatus400may be configured to feed water and nutrients to the seeds, or to the plants which grow from said seeds, by means of the irrigation troughs422a,422b, arranged below the mat carriers454a,454b, of the irrigation apparatus (not illustrated). Furthermore, the apparatus400may be configured to irradiate the seeds, or the plants which grow from said seeds, by means of the LED modules432a,432bof the illumination apparatus430.

Here, the illustration ofFIG. 6Ashows the air movements for the climate control of the accommodating space of the apparatus in a semi-frontal view, whereas the illustration ofFIG. 6Bshows the air movements for the climate control of the accommodating space of the apparatus in a rear-side detail view, and the illustration ofFIG. 6Cshows a detail illustration of particular air movements.

For a simpler explanation of the air movements that occur during the climate control of the accommodating space, the same reference symbols have been used in all three illustrations. It is to be noted that not all elements are visible or illustrated in all of the illustrations ofFIG. 6A,FIG. 6BandFIG. 6C. For example, onlyFIG. 6Aillustrates that the apparatus for growing plants600includes a housing610with a base614, which is configured to accommodate a water tank613, and includes an accommodating space612, which is configured to accommodate irrigation troughs622a,622b, wherein, for the sake of simplicity of the illustration, the housing610is illustrated in cross section, wherein a front of the housing610and a side wall of the housing610have been omitted. On the other hand, only the detail view ofFIG. 6Billustrates that a climate control device40(not illustrated, seeFIG. 1) includes a cooling appliance641, wherein the cooling appliance641includes a condenser642, an evaporator644and a compressor646. On the other hand again, the detail view ofFIG. 6Cillustrates only a part of the region of the upper storey605bof the apparatus600.

The climate control device may include one or more cooling blowers (not illustrated inFIG. 6A; see cooling blowers548a,548binFIG. 5), wherein the cooling blowers may, as stated with reference to the cooling blowers548ofFIG. 5, be configured to draw the air out of the accommodating space612of the apparatus600(see arrows661a,661b), as illustrated inFIG. 6A. In various embodiments, the one or more cooling blowers may be provided on a rear side plate607such that the one or more cooling blowers are arranged between the rear side plate607and a rear side wall606of the apparatus600.

For example, the climate control device may include a first cooling blower and a second cooling blower.

Likewise, the second cooling blower may for example be arranged so as to draw the air out of an accommodating space612in the region of an upper storey605b(arrow661b). In other words, the first cooling blower may for example be configured to draw the air out of the accommodating space612in the region of the lower storey605a(arrow661a), whereas the second cooling blower may for example be configured to draw the air out of the accommodating space612in the region of the upper storey605b(arrow661b).

As discussed with reference toFIG. 5, the climate control device may furthermore include a cooling appliance641(seeFIG. 6B), which in turn may include a condenser642, an evaporator644and a compressor646(only partially illustrated in the view ofFIG. 6A).

By means of the specific arrangement of the evaporator644between the rear side plate607and the rear side wall606of the housing610, the climate control device may for example be configured to conduct the air that is drawn out of the accommodating space612by the cooling blowers through between the rear side plate607and the rear side wall606(arrows662a,662b). Here, the apparatus600may furthermore be configured to conduct the air that is drawn out of the accommodating space612by means of the cooling blowers past the evaporator644(arrows662a,662b).

More specifically, the climate control device may be configured to conduct the air that is drawn out of the region of the lower storey605aby means of the first cooling blower (arrow661a) and the air that is drawn out of the region of the upper storey605bby means of the second cooling blower (arrow661b) through the space between the rear side wall606and the rear side plate607, and in the process past the evaporator644(arrows662a,662b).

As already described with reference toFIG. 5, in various embodiments, the rear side plate607may include one or more air inlet openings649on a side which is situated opposite a side at which the cooling blowers548a,548bare arranged. For example, the rear side plate607may include first air inlet openings649aand second air inlet openings649b. Here, the first air inlet openings649amay for example be arranged so as to connect the space between the rear side wall606and the rear side plate607to the region of the lower storey605aof the accommodating space612. The second air inlet openings649bmay for example be arranged so as to connect the space between the rear side wall606and the rear side plate607to the region of the upper storey605bof the accommodating space612.

In this way, the apparatus600may be configured to conduct the air flowing past the evaporator644(arrows662a,662b) back into the accommodating space612via the air inlet openings649a,649b(arrows663a,663b).

For example, the controller may be configured to actuate the climate controller such that the cooling blowers cause such a quantity of air to flow past the evaporator644(arrows662a,662b) that the temperature of the air in the accommodating space612is lowered. In other words, the controller may actuate the climate control device such that the temperature of the air that is conducted back into the accommodating space612via the air inlet openings649a,649b(arrows663a,663b) is regulated. For example, the controller may actuate the climate control device such that the temperature of the air that is conducted back into the accommodating space612via the air inlet openings649a,649b(arrows663a,663b) is set to a temperature beneficial to the growth of the plants introduced into the accommodating space.

Furthermore, in various embodiments, the controller60of the apparatus600may be configured to actuate the climate control device such that a content of air humidity in the air flowing past the evaporator644(arrows662a,662b) is lowered as said air flows past. For example, the controller may be configured to actuate the climate controller such that the cooling blowers cause such a quantity of air to flow past the evaporator644(arrows662a,662b) that the humidity content of the air in the accommodating space612is lowered. In other words, the controller may actuate the climate control device such that the air humidity of the air that is conducted back into the accommodating space612via the air inlet openings649a,649b(arrows663a,663b) is regulated. For example, the controller may actuate the climate control device such that the air humidity of the air that is conducted back into the accommodating space612via the air inlet openings649a,649b(arrows663a,663b) is set to an air humidity content beneficial to the growth of the plants introduced into the accommodating space.

For this purpose, the climate control device may be configured to conduct such a quantity of air from the accommodating space612past the evaporator644(arrows662a,662b), and at the same time cool the evaporator644to such an extent, that a part of the water present (or located) in the air condenses on the evaporator644. In this way, the content of air humidity in the accommodating space612may be lowered.

On the other hand, in various embodiments, the irrigation unit20(not illustrated, seeFIG. 1), actuated by the controller, may be configured to feed water to the irrigation troughs622a,622bby means of a water circuit system, as described with reference toFIG. 2. Here, the irrigation unit, actuated by the controller, may be configured to fill the irrigation troughs622a,622bfor example at regular intervals, wherein water may evaporate. This may cause the content of air humidity in the accommodating space612to be increased.

For this purpose, the apparatus600may for example be configured to conduct the air that is pumped out of the accommodating space612(arrows661a,661b) through a suitable pipe (not illustrated), for example a UV-permeable pipe composed of quartz glass (not illustrated), and in the process irradiate said air with light in the UV-C range such that, in the process, germs that are present in the air pumped out of the accommodating space612, for example fungi, fungal spores and/or bacteria, are killed. In other words, the apparatus600may be configured to sterilize the air that is pumped out of the accommodating space612(arrows661a,661b) by irradiation with light in the UV-C range before said air is conducted back into the accommodating space612through the inlet openings649a,649b(arrows663a,663b).

In other words, the control device may be configured to receive determined measured values, or in other words determined sensor values, for the air temperature and the air humidity in the accommodating space612from the temperature sensors and the air humidity sensors of the apparatus600.

Here, in various embodiments, as already described with reference toFIG. 3, the controller may be configured to regulate an interior space climate prevailing in the accommodating space612by means of the climate control device on the basis of the sensor values determined for the air humidity and for the air temperature.

Furthermore, the controller may include a pattern recognition apparatus (not illustrated) and an associated pattern recognition memory (not illustrated) and be configured to receive signals from the camera and transmit said signals to the program controller. Furthermore, the controller may be configured to, by means of the pattern recognition apparatus, compare the images recorded by means of the camera with one or more reference images stored in the pattern recognition memory in order to determine a state of the plants accommodated in the accommodating space, in order to thus adapt the program controller to the respective plant and to the state of said plant.

As illustrated inFIG. 7, in various embodiments, the housing710of the apparatus for growing plants700furthermore includes a fresh-air blower770. The fresh-air blower770may for example be arranged in a lower region of a side wall703of the apparatus700. For this purpose, the side wall703may include an aperture703ain the lower region, wherein the fresh-air blower770may be arranged such that it may draw air in from the surroundings of the apparatus700through the aperture703a. Alternatively, the fresh-air blower770may for example be arranged in a base region714of a front side of the apparatus700(not illustrated).

The fresh-air blower770may be configured to be actuated by the controller60(not illustrated; seeFIG. 1) by means of the climate control device40(not illustrated; seeFIG. 1). The controller may be configured to actuate the climate control device such that fresh air is pumped by means of the fresh-air blower770from surroundings of the apparatus700into the accommodating space712of the apparatus700. In other words, the control device may be configured to actuate the fresh-air blower770such that ambient air is blown into the accommodating space712.

The apparatus700may furthermore include air outlet openings772. The air outlet openings772may for example be arranged in an upper region of the accommodating space712. For example, the air outlet openings772may be arranged on a top panel708of the housing710. The air outlet openings772may be configured to allow air to flow out of the accommodating space712to the outside. Here, the air outlet openings772may be configured to prevent a positive pressure from forming in the accommodating space712.

The apparatus700may furthermore include at least one activated carbon filter771which is configured to filter the air that is drawn in from the surroundings by means of the fresh-air blower770. The at least one activated carbon filter771may for example be arranged between the fresh-air blower770and the accommodating space712. Here, the at least one activated carbon filter771may be configured to filter dust and other particles out of the ambient air such that these do not pass into the accommodating space712of the apparatus.

Furthermore, the apparatus may include further activated carbon filters773, which are arranged at the air outlet openings772. The activated carbon filters773at the air outlet openings772may be configured to filter the air flowing out of the accommodating space712, such that any odors that are possibly generated in the accommodating space712are not released into the surroundings.

Furthermore, in various embodiments, the apparatus700may include a temperature sensor718for determining an ambient temperature. The ambient temperature sensor718may for example likewise be arranged in the aperture703aof the side wall703. Alternatively, the ambient temperature sensor718may for example be arranged in the base region714of the front side of the apparatus700(not illustrated).

In various embodiments, the controller may be configured to actuate the fresh-air blower770such that fresh air from the surroundings is fed to the accommodating space712. The controller may for example be configured to actuate the fresh-air blower770such that fresh air from the surroundings is fed to the accommodating space712at preset times, for example at preset times of the day. Alternatively, the controller may be configured to actuate the fresh-air blower770such that fresh air from the surroundings is fed to the accommodating space712at regular intervals.

Furthermore, in various embodiments, the controller may be configured to actuate the fresh-air blower770such that fresh air is fed to the accommodating space712if the CO2content in the accommodating space712becomes too high. For this purpose, the apparatus700may additionally include a CO2sensor717for determining a CO2content of the air in the accommodating space712. The CO2sensor717may be arranged in the side wall703of the housing710. For example, the CO2sensor717may be arranged together with, or in other words in the vicinity of, the temperature sensor316band the air humidity sensor315b(seeFIG. 3) in the region of the upper storey305bof the accommodating space on an inner side of the side wall703. Alternatively, the air humidity sensor, the temperature sensor and the CO2sensor717may be designed, or in other words formed, as a combined air humidity-temperature-CO2sensor717.

The controller may be configured to receive sensor data from the CO2sensor717. Furthermore, the controller may be configured to actuate the fresh-air blower770by means of the climate control device on the basis of the data received from the CO2sensor717, for example on the basis of measured values received from the CO2sensor717, such that the CO2content of the air in the accommodating space712does not exceed a preset value.

FIG. 8shows a flow diagram of a method for growing plants according to various embodiments.

As illustrated inFIG. 8, in various embodiments, the method for growing plants includes introducing one or more seed mats into an accommodating space of an apparatus for growing plants,810, actuating an irrigation apparatus, an illumination apparatus and a climate control device of the apparatus for growing plants by means of a program controller of a controller,820, determining an air humidity in the accommodating space by means of at least one air humidity sensor,830, and determining an air temperature in the accommodating space by means of at least one temperature sensor,840.

Here, in various embodiments, the method may furthermore include feeding measured values from the air humidity sensor and/or from the temperature sensor to the controller. In other words, the controller may receive measured values determined by means of the sensors, or in other words sensor values determined by means of the sensors for the air humidity and/or for the air temperature, that is to say by means of the air humidity sensor and/or by means of the temperature sensor.

Furthermore, the method may include regulating an interior space climate prevailing in the accommodating space by means of the climate control device by means of the controller. For example, the method may include regulating, by means of the controller, an interior space climate prevailing in the accommodating space by means of the climate control device on the basis of the sensor values determined for the air humidity and for the air temperature. Here, the controller may for example regulate the air temperature on the basis of the determined temperature sensor values. Furthermore, the controller may regulate the air humidity on the basis of the determined air humidity values.

For example, the air temperature and/or the air humidity in the accommodating space may be adjusted by means of a cooling appliance of the climate control device by actuation of the controller, wherein the cooling appliance optionally includes an evaporator. The controller may for example lower the air temperature in the accommodating space by means of the cooling appliance. In other words, the controller may cool the air in the accommodating space by means of the cooling appliance.

On the other hand, the controller may increase the air temperature in the accommodating space by means of a light quantity radiated by the illumination apparatus. For example, the controller may increase the air temperature in the accommodating space by means of a heat quantity radiated by the illumination apparatus. In other words, the controller may actuate the illumination apparatus such that the air temperature in the accommodating space is increased by means of a heat quantity radiated by the illumination apparatus in addition to the light, in other words by means of heat energy radiated by the illumination apparatus.

The illumination apparatus may emit light by means of an LED module for each of the growing units introduced into the accommodating space. Here, each of the LED modules may emit light of a wide variety of spectral compositions. For example, the LED modules may, by means of a multiplicity of LEDs, for example three or four LEDs, wherein each of the LEDs respectively includes one color channel, emit light of the corresponding color. In other words, the LED modules may, by means of the LEDs, emit light in for example three or four different color channels. Here, each LED module may be dimmed, or in other words regulated or varied, between 0% and 100%. Alternatively, each of the LEDs may be dimmed, or in other words regulated or varied, individually between 0% and 100%, for example by means of pulse width modulation (PWM) or by means of the applied voltage.

Each LED module may for example, by means of at least one LED, emit light in the blue range of the spectrum, for example in a range from approximately 430 nm to approximately 490 nm, for example in a range from approximately 440 nm to approximately 475 nm, for example in a range from approximately 450 nm to 460 nm. Furthermore, each LED module may for example, by means of at least one LED, emit light in the red range of the spectrum, for example in a range from approximately 640 nm to approximately 700 nm, for example in a range from approximately 650 nm to approximately 680 nm, for example in a range from approximately 660 nm to 670 nm. Furthermore, each LED module may for example, by means of at least one LED, emit light in the dark red range of the spectrum, for example in a range from approximately 700 nm to approximately 780 nm, for example in a range from approximately 720 nm to approximately 760 nm, for example in a range from approximately 730 nm to 740 nm. Furthermore, each LED module may for example, by means of at least one LED, emit light in a composition of the spectrum such that white light is emitted.

Here, each of the LED modules may emit light by means of a different number of LEDs of the respective wavelength. For example, each LED module may emit light for illuminating the accommodating space of the apparatus, or for illuminating the plants introduced into the accommodating space, by means of at least one LED which emits light with a wavelength of 450 nm, at least one LED which emits light with a wavelength of 660 nm, at least one LED which emits light with a wavelength of 730 nm, and at least one LED which emits white light, for example in a composition such that white light with a peak in the green range is emitted. Alternatively, each of the LED modules may for example emit light for illuminating the accommodating space of the apparatus, or for illuminating the plants introduced into the accommodating space, by means of one LED which emits light with a wavelength of 450 nm, two LEDs which emit light with a wavelength of 660 nm, one LED which emits light with a wavelength of 730 nm, and one LED which emits white light, for example in a composition such that white light with a peak in the green range is emitted. Here, the LED modules may however also emit light by means of a different respective number of LEDs of the different wavelengths. Furthermore, other LED modules with LEDs which emit light of other wavelengths may be used if this is beneficial to the germination of the seeds introduced into the accommodating space or to the growth of the plants which grow from said seeds.

In various embodiments, the controller may actuate each of the LED modules such that an illumination duration (or illumination period), an illumination intensity and a composition of the illumination spectrum, or in other words a composition of the emitted wavelength ranges, is regulated, or in other words controlled or adjusted or varied.

In the method for growing plants, furthermore, in various embodiments, the air humidity in the accommodating space may be regulated. For example, the controller may regulate the air humidity in the accommodating space by means of the evaporator. For example, the controller may actuate the climate control device such that the air humidity is lowered by means of the evaporator. On the other hand, the controller may actuate the climate control device such that the air humidity increases, wherein the air humidity increases by evaporation of water which is fed by means of the irrigation apparatus to the plants arranged in the accommodating space. Furthermore, water at the roots and in the leaves of the plants growing in the accommodating space may evaporate and may be released by means of the photosynthesis activity and the respiration of the plants growing in the accommodating space.

In the method for growing plants, furthermore, water which condenses as the air flows past the evaporator may run off and be collected in the water tank of the irrigation apparatus, such that said condensed water is fed to the water circuit system of the irrigation apparatus.

In various embodiments, the method for growing plants may furthermore include purifying the air in the accommodating space. In other words, in the method, the air in the accommodating space may be purified. For example, the air in the accommodating space may be purified by irradiation with light in the UV-C range. For this purpose, the air pumped out of the accommodating space (see arrows661a,661binFIG. 6) may be conducted through a suitable pipe, for example a UV-permeable pipe composed of quartz glass, and in the process irradiated with light in the UV-C range such that, in the process, germs that are present in the air pumped out of the accommodating space, for example fungi, fungal spores and/or bacteria, are killed. In other words, in the method for growing plants, the air that is pumped out of the accommodating space (see arrows661a,661binFIG. 6) may be sterilized by irradiation with light in the UV-C range before said air flows back into the accommodating space through the inlet openings (see arrows663a,663binFIG. 6).

In various embodiments, the method may furthermore include cooling air present in the accommodating space by means of at least one cooling blower of the climate control device. For example, the controller may actuate the climate control device such that the air present (or located) in the accommodating space is cooled by means of the cooling blower. As already discussed with reference toFIG. 6A, the air present in the accommodating space may, for this purpose, be drawn out of the accommodating space by means of the cooling blower. The air may then be conducted past the evaporator arranged on a rear side wall of the apparatus and conducted via specific air inlet openings back into the accommodating space, wherein the air that flows past the evaporator is cooled such that the air conducted back into the accommodating space is cooler than the air drawn out of the accommodating space.

Furthermore, in various embodiments, the method may include introducing one or more growing units into the accommodating space, wherein each growing unit forms a storey in the accommodating space, and wherein each growing unit includes an irrigation trough, at least one LED module and one or more mat carriers, and placing one or more seed mats onto each of the mat carriers, wherein each of the seed mats includes seeds (or already-germinated plants).

In other words, in the method for growing plants, it is furthermore possible for one or more growing units to be introduced into the accommodating space. Here, each of the growing units may include an irrigation trough, at least one LED module and one or more mat carriers, and may be arranged in the accommodating space such that one storey in the accommodating space is respectively formed by each of the growing units. For example, a lower growing unit with a first (for example a lower) irrigation trough, a first (for example a lower) LED module and one or more mat carriers may be arranged in the accommodating space so as to form a lower storey. Furthermore, an upper growing unit with a second (for example an upper) irrigation trough, a second (for example an upper) LED module and one or more mat carriers may be arranged in the accommodating space so as to form an upper storey.

In various embodiments, one or more seed mats may be placed onto each of the mat carriers. Here, each of the seed mats may include seeds, wherein plants may grow from the seeds. Alternatively, the seed mats may include already-germinated plants, and may be introduced with the germinated plants into the accommodating space. Here, the controller may actuate the climate control device such that an interior space climate conducive to plant growth is set in the accommodating space or in the region of each storey.

In the method for growing plants, the air in each storey may be cooled by means of a separate cooling blower. In other words, the air temperature in the accommodating space may be individually regulated in the region of each storey by means of the controller. For example, the controller may actuate the cooling blower for the lower storey such that the air temperature in the region of the lower storey is lowered. Likewise, the controller may actuate the cooling blower for the upper storey such that the air temperature in the region of the upper storey is lowered. In this way, the air temperature in the region of the individual storeys may be separately regulated by means of the climate control device actuated by the controller.

Furthermore, each LED module may be cooled by means of a separate LED cooling blower. For example, the lower LED module may be cooled by means of the lower LED cooling blower. Furthermore, the upper LED module may be cooled by means of the upper LED cooling blower. For this purpose, the lower LED cooling blower and the upper LED cooling blower may draw ambient air in for example from rear-side surroundings of the apparatus for growing plants and conduct said air past the first LED module and the second LED module respectively. For example, the LED cooling blowers may draw ambient air in and conduct it past cooling fins arranged over the LED modules such that heat generated by the LED modules is dissipated.

In various embodiments, the method for growing plants may furthermore include circulating air in the accommodating space by means of at least one blower of the climate control device, and feeding fresh air by means of at least one fresh-air blower of the climate control device. In other words, the controller may on the one hand actuate the climate control device such that the air present in the accommodating space is circulated by means of the at least one blower. In various embodiments, for the regulation of the interior space climate in the accommodating space in the method for growing plants, the controller may on the other hand actuate the fresh-air blower such that fresh air from the surroundings is fed to the accommodating space. For example, the controller may actuate the fresh-air blower such that fresh air from the surroundings is fed to the accommodating space at preset times, for example at preset times of the day. Alternatively, the controller may actuate the fresh-air blower such that fresh air from the surroundings is fed to the accommodating space at regular intervals. Here, excess air may flow back into the surroundings via air outlet openings arranged on the front side of the apparatus.

Furthermore, in various embodiments, the controller may actuate the fresh-air blower such that fresh air is fed to the accommodating space if the CO2content in the accommodating space becomes too high. For this purpose, the method may additionally include determining a CO2content of the air in the accommodating space by means of a CO2sensor. The CO2sensor may, as described with reference toFIG. 7, be arranged for example in the side wall of the housing of the apparatus. For example, the CO2sensor may be integrated in a combined air humidity-temperature-CO2sensor.

The CO2sensor may transmit measured signals relating to the CO2content of the air in the accommodating space to the controller. In other words, the controller may receive sensor data from the CO2sensor. Furthermore, the controller may actuate the fresh-air blower by means of the climate control device on the basis of the data received from the CO2sensor, for example on the basis of measured values received from the CO2sensor, such that the CO2content of the air in the accommodating space does not exceed a preset value. This may be ensured by virtue of fresh air from the surroundings of the apparatus for growing plants being blown into the accommodating space by means of the fresh-air blower.

The fresh air fed to the accommodating space by means of the fresh-air blower may furthermore be filtered by means of activated carbon filters such that no dust or other contaminants in the ambient air are blown into the accommodating space, and, when the fresh-air blower is deactivated, no odors can flow out of the accommodating space. Furthermore, the air that flows back into the surroundings from the accommodating space may in this case be filtered by means of further activated carbon filters at the air outlet openings such that no odors are released from the accommodating space into the surroundings.

In various embodiments, in the regulation of the climate control device, the controller may regulate the interior space climate in each storey, or in other words the microclimate, by means of climate control data, adapted individually to the seeds accommodated in the corresponding storey of the accommodating space, of the program controller. In other words, the program controller may include climate control data, wherein the climate control data may be adapted to the seeds arranged on the seed mats (or to the plants growing on said seed mats). In accordance with the climate control data, the controller may actuate the climate control device such that an interior space climate, that is to say microclimate, adapted to the corresponding introduced seeds is set in each of the storeys.

For example, the program controller may include climate control data adapted to the seeds (or the plants) arranged (or growing) on the seed mats placed onto the lower mat carriers. In accordance with said climate control data, the controller may set, in the region of the lower storey, a microclimate which is adapted to the growth of the plants growing on the lower mat carrier. Furthermore, the program controller may include climate control data adapted to the seeds arranged on the seed mats placed onto the upper mat carriers. In accordance with said climate control data, the controller may set, in the region of the upper storey, a microclimate which is adapted to the growth of the plants growing on the upper mat carrier.

In various embodiments, the method may furthermore include accessing, from a data memory of the program controller, illumination data and/or irrigation data and/or climate control data individually adapted to the seeds. For example, the illumination data and/or irrigation data and/or climate control data individually adapted to the seeds may be accessed by means of the controller from a data memory of the program controller. Subsequently, the controller may actuate the illumination apparatus, the irrigation apparatus and the climate control device on the basis of the illumination data and/or irrigation data and/or climate control data individually adapted to the seeds such that, in the accommodating space, an interior space climate conducive to the growth of the plants growing therein is set.

Here, the data memory may be provided as an external data memory by means of an Internet connection provided in the apparatus for growing plants. In other words, the controller may access corresponding data from an external data memory by means of an Internet connection which is provided by means of corresponding antennae of the apparatus for growing plants.

In various embodiments, the method may furthermore include identifying at least one seed mat by means of a program sensor for the control of the program controller. For example, the controller may detect RFID signals or a QR label or a barcode of the at least one seed mat by means of the program sensor for the control of the program controller. Here, the program sensor may be provided as an RFID sensor and/or QR code sensor and/or barcode sensor. In other words, the controller may identify the seeds arranged on the respective seed mat (or the plants that have germinated on the respective seed mat) by means of the RFID signals or the QR label or the barcode of the seed mats, access the climate control data adapted to the respective seeds (or to the respective plants) from the data memory, and adjust the interior space climate prevailing in the accommodating space to the respective seeds (or to the respective plants).

In this way, in various embodiments, in accordance with the method for growing plants, the interior space climate adapted to the seeds may be adjusted by means of the controller. For example, the controller may produce a microclimate adapted to the respective seeds growing in the corresponding growing unit by means of the program controller on the basis of the accessed climate control data. In other words, the controller may actuate the irrigation apparatus, the illumination apparatus and the climate control device on the basis of the accessed climate control data such that a microclimate adapted to the seeds in the corresponding growing unit is set.

In various embodiments, in the method, the irrigation apparatus may furthermore feed water and nutrients to the irrigation troughs which are arranged in each of the one or more growing units under the respective seed mats. In other words, in the method for growing plants, in each growing unit, water and nutrients may be fed by the irrigation apparatus, by means of the irrigation troughs, to the seeds arranged on the seed mats or to the plants growing from said seeds.

Furthermore, the method for growing plants may include recording images of the plants growing from the seeds accommodated in the accommodating space by means of at least one camera. Here, the method may furthermore include the steps of transmitting signals from the at least one camera to the program controller, comparing the images recorded by means of the camera with one or more reference images stored in a pattern recognition memory of the controller in order to determine a state of the plants accommodated in the accommodating space by means of a pattern recognition apparatus of the controller, and adapting the program controller to the respective plant and to the state of said plant.

In detail, the camera arranged in the apparatus may record images by means of which, using stored reference images, the growth progress and thus the state of the plants growing in the accommodating space may be determined. For this purpose, the controller may transmit the images recorded by the camera to the program controller. The reference images for the comparison of the recorded images may be stored in the external data memory. The controller may furthermore, by means of the pattern recognition apparatus, compare the images recorded by the camera with the stored reference images and, from this, determine the growth progress or a present state of the plants. Furthermore, the controller may actuate the program controller such that an interior space climate adapted to the state of the plants in the accommodating space is set in the accommodating space. For example, the program controller may be actuated so as to set a microclimate adapted to the plants growing in each storey of the accommodating space.

In various embodiments, by means of the identification of the seeds and the determination of the present state of the plants growing from said seeds, the controller may thus actuate the irrigation apparatus, the illumination apparatus and the climate control device such that an interior space climate or microclimate adapted to the respective plants growing in the growing unit, and to the state of said plants, for example to the growth progress of said plants, is produced.

In various embodiments, the method may furthermore include determining whether a door of the apparatus is open or closed by means of a door sensor. In other words, in the method for growing plants, furthermore, it may be determined, by means of the door sensor, whether a door of the apparatus is open or closed. Here, the door sensor may optionally be an IR sensor. For this purpose, the door sensor may transmit the corresponding measured signals to the controller. In other words, the controller may receive signals from the door sensor.

In various embodiments, the controller may, when the door is open, actuate the irrigation apparatus, the illumination apparatus and the climate control device such that the user can for example handle the seed mats in the accommodating space. This means that, when the door is open, the controller may for example actuate the illumination apparatus such that light of a spectral composition in which the user can see clearly (or in other words of a spectral composition visible to the user) is emitted, and may actuate the climate control device such that the at least one cooling blower is deactivated. In other words, the controller may for example, when the door is open, actuate the illumination apparatus such that light of a spectral composition is emitted such that the accommodating space is illuminated normally for a user, and he or she can see clearly but is not blinded, or his or her eyes are not damaged. Furthermore, the controller may for example, when the door is open, actuate the climate control device such that the cooling blower does not run, such that a noise level prevailing in the apparatus is reduced when the door is open, and the energy consumed by the cooling blower is reduced. Furthermore, the controller may for example, when the door is open, actuate the irrigation apparatus such that no water is fed to the irrigation troughs, such that the user can for example remove seed mats or plants from the accommodating space or introduce new seed mats or plants into the accommodating space without the risk of water being spilt.

For example, the controller may, when the door is open, actuate the irrigation apparatus such that no water is circulated by pumping in the water circuit system, and may, when the door is closed, actuate the irrigation apparatus such that water from the water tank is circulated by pumping in the water circuit system. Likewise, the controller may for example actuate the water circuit system such that, when the door is open, no water from the water tank is fed to the irrigation troughs and, when the door is closed, water from the water tank is fed to the irrigation troughs. Furthermore, the controller may actuate the water circuit system such that, when the door is open, no water from the water tank is fed to an apparatus for purifying the water and, when the door is closed, water from the water tank is fed to the apparatus for purifying the water. In this way, it is possible to prevent water overflowing from or running out of the irrigation troughs in an uncontrolled manner in the event of the door being open during the filling of the irrigation troughs, whereby a consumer, for example when handling the seed mats or plants arranged over the irrigation troughs, is protected from becoming wet or from spilling water in the surroundings of the apparatus.

By contrast, in various embodiments, when the door is closed, the controller may actuate the irrigation apparatus, the illumination apparatus and the climate control device such that, again, the interior space climate adapted to the respective plants growing in the growing unit, and to the state of said plants, is produced. For example, the illumination apparatus may be actuated by the controller such that light in a wavelength range which is particularly conducive or beneficial to the germination of the seeds or to plant growth, for example with a mixture of light in the wavelength range for green light and for red light of the spectrum, or in some other spectral composition, is emitted. For example, the illumination apparatus may emit light of an above-described spectral composition of light with a wavelength of 450 nm, light with a wavelength of 660 nm and light with a wavelength of 730 nm. Furthermore, the climate control device may be actuated by the controller such that the at least one cooling blower is activated when this is necessary for maintaining the interior space climate in the accommodating space.

For example, the climate control device may be actuated by the controller such that the air in the accommodating space is warmed or cooled by virtue of the cooling blower being activated if the air temperature in the accommodating space is too high or by virtue of the cooling blower being deactivated if the air temperature in the accommodating space is too low. Furthermore, the irrigation device may be actuated by the controller such that water and nutrients are fed to the irrigation troughs such that the plants are provided with an optimal supply.

Altogether, the embodiments, provided here, of the apparatus for growing plants and of a method for growing plants can ensure the provision of an environment in which plants, such as for example herbs, vegetables, mushrooms, fruit and salad, can be grown from seeds on a scale that is also practicable in modern kitchens. In this way, by means of the present apparatus, it is made possible for the average consumer, in particular residents of large cities, to add fresh ingredients to their diet in accordance with their personal, and in so doing to firstly ensure a desired quality and secondly limit the effort required for this to the level that is possible in modern working life.
