  Hereinafter, as one embodiment of the present invention, an example in which the present invention is applied to a temperature control device used in a hydroponics unit will be described with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 1, the hydroponics unit 1 includes a shelf (furniture) 2, a lighting device 3, a temperature control device 4, and a cultivation container 5. The temperature adjustment device 4 is placed on the shelf 2 a of the shelf 2. The temperature control device 4 accommodates three cultivation containers 5 in this embodiment. The temperature control device 4 heats or cools the cultivation container 5. The cultivation container 5 accommodates water for hydroponics (a liquid containing nutrients). The cultivation container 5 is provided with a culture medium for growing the plant S. The lighting device 3 is installed on the lower surface side of the top plate 2 b of the shelf 2. The plant S grows by receiving light irradiated from the lighting device 3. In addition, the shape of the shelf 2 is not limited to the shape shown in FIG. 1, and may be another shape as long as the lighting device 3 can be attached above the temperature control device 4 that accommodates the cultivation container 5.

  Hereinafter, the temperature control device 4 will be described in detail. As shown in FIGS. 2 and 3, the temperature adjustment device 4 includes a main body portion 11, a bottom portion 12, a lid portion 13, a heat conductor 14, and a first heat source 15. The main body 11, the bottom 12, and the lid 13 are heat insulating materials. The main body part 11, the bottom part 12 and the lid part 13 are constituted by, for example, a phenol resin, a polystyrene resin, a phenol resin foam or a polystyrene resin foam.

  The heat conductor 14 is a member that transfers heat. The heat conductor 14 is made of a member having high heat conductivity, and is made of a metal such as aluminum or copper as an example. The heat conductor 14 is formed in a plate shape, a rod shape, or a pipe shape, for example. In addition to the metal, the heat conductor 14 may be provided with a refrigerant pipe to transmit heat using a refrigerant such as ethylene glycol or water. The bottom portion 12 is disposed on the lower surface side of the main body portion 11. The heat conductor 14 is sandwiched between the main body portion 11 and the bottom portion 12. That is, the heat conductor 14 is included in the main body 11 and the bottom 12 which are heat insulating materials.

  On the upper surface of the main body portion 11, three accommodating portions 11 a, 11 b, and 11 c that are formed in a concave shape toward the heat conductor 14 so as to surround the outer shape of the cultivation container 5 are provided. In this embodiment, the accommodating parts 11a-11c are formed in the shape in alignment with the external shape of the cultivation container 5. As shown in FIG. The upper surface of the heat conductor 14 is exposed in the accommodation space Ra in the accommodation part 11a, the accommodation space Rb in the accommodation part 11b, and the accommodation space Rc in the accommodation part 11c. The accommodating portions 11a to 11c have larger diameters as they proceed upward so as to wrap along the shape of the side wall of the cultivation container 5 in a sectional view. The depth of the accommodating portions 11 a to 11 c (the thickness in the vertical direction of the main body portion 11) is substantially the same as the height of the cultivation container 5. The accommodating parts 11a-11c can accommodate the cultivation container 5, respectively. Thereby, when each cultivation container 5 is accommodated in accommodating part 11a-11c, the bottom face of each cultivation container 5 will be in the state which was mounted on the upper surface of the exposed heat conductor 14, and contacted.

  Furthermore, a first heat source housing portion 11 d formed in a shape that is recessed toward the heat conductor 14 is provided on the upper surface of the main body portion 11. The upper surface of the heat conductor 14 is exposed in the first heat source housing space Rd in the first heat source housing 11d. The first heat source 15 is accommodated in the first heat source accommodating portion 11d. The accommodating portions 11a to 11c and the first heat source accommodating portion 11d are provided side by side along the horizontal direction in the order of the accommodating portions 11a to 11c and the first heat source accommodating portion 11d. The heat conductor 14 extends from the housing portion 11a to the first heat source housing portion 11d.

  The first heat source 15 includes a Peltier element 15a that can be heated and cooled. In addition to the Peltier element 15a, the first heat source 15 includes a radiator and a fan used to operate the Peltier element 15a. The Peltier element 15a contacts and is thermally connected to a portion of the upper surface of the heat conductor 14 exposed to the first heat source accommodation space Rd. By operating the Peltier element 15a, the heat conductor 14 can be heated and cooled. When each cultivation container 5 is accommodated in the accommodating portions 11a to 11c, the bottom surface of each cultivation container 5 is placed on and in contact with the exposed upper surface of the heat conductor 14, so that the heat conductor 14 is The heat generated by the first heat source 15 is transmitted to the cultivation container 5. In addition, the heat conductor 14 transferring heat means transferring high heat generated by the first heat source 15 to the cultivation container 5 and low heat generated by the first heat source 15. Including communicating to.

  The lid portion 13 covers the upper opening of the first heat source accommodation space Rd. The first heat source accommodation space Rd is not limited to a closed space, and an exhaust port or the like may be provided on the side surface of the main body 11 or the like. Heat or the like when the Peltier element 15a is operated may be discharged from the first heat source accommodation space Rd through the exhaust port. Without providing the lid portion 13, the first heat source accommodation space Rd may be a space having an open top. Moreover, the efficiency of the temperature adjustment of a to-be-contained object can also be improved by making the cover part 13 into a heat insulating material.

  Next, heating or cooling of the cultivation container 5 using the temperature control device 4 will be described. The temperature control device 4 installs the spacer member 21 or the shielding material 22 in the accommodating portions 11a to 11c, and directly cultivates the accommodating portions 11a to 11c, in addition to directly accommodating the cultivation container 5 in the accommodating portions 11a to 11c. The cultivation container 5 can be accommodated with the spacer member 21 or the shielding material 22 interposed between the container 5 and the container 5. Thereby, the degree of the heating or cooling of the water in the cultivation container 5 by the heat conductor 14 can be adjusted. Specifically, as shown in FIG. 4, for example, the cultivation container 5 is directly accommodated in the accommodation portion 11 a. The bottom surface of the cultivation container 5 contacts the heat conductor 14 exposed in the accommodation space Ra of the main body 11. Thereby, the water in the cultivation container 5 is heated or cooled by the heat conductor 14.

  For example, the cultivation container 5 is accommodated in the accommodating portion 11b in a state where the spacer member 21 is installed on the side surface rising obliquely in the accommodating portion 11b. The spacer member 21 is formed in a cylindrical shape along the side surface shape of the housing portion 11b, and when the cultivation container 5 is housed in the housing portion 11b, the spacer member 21 includes the side surface of the housing portion 11b and the side wall of the cultivation container 5. It is in a state of being sandwiched between. By installing the spacer member 21, the cultivation container 5 is in a floating state without completely sinking to the bottom of the housing portion 11 b, so that it is exposed to the housing space Rb in the housing portion 11 b of the upper surface of the heat conductor 14. The distance between the part to be performed and the bottom surface of the cultivation container 5 can be separated. Thereby, the grade of the heating or cooling temperature of the water in the cultivation container 5 by the heat conductor 14 can be adjusted. By changing the thickness of the spacer member 21, the distance between the portion exposed to the accommodation space Rb in the upper surface of the heat conductor 14 and the bottom surface of the cultivation container 5 can be changed. That is, by changing the thickness of the spacer member 21, the degree of water heating or cooling in the cultivation container 5 can be adjusted. As an example, the spacer member 21 can be formed of various resins such as polypropylene resin. The shape of the spacer member 21 is not limited to a cylindrical shape as long as the distance between the bottom surface of the cultivation container 5 and the heat conductor 14 can be separated, may be a cup shape, or may be a shape other than these, What is necessary is just to provide suitably according to the accommodating parts 11a-11c.

  For example, the cultivation container 5 is accommodated in the accommodating part 11c in a state where the shielding member 22 is installed in the accommodating part 11c. The shielding material 22 is a plate-like member, and is placed on a portion of the upper surface of the heat conductor 14 that is exposed to the accommodation space Rc in the accommodation portion 11c. The shielding material 22 shields the heat transmitted from the heat conductor 14 to the cultivation container 5. The shielding material 22 can be formed of foamed polystyrene as an example. By installing the shielding material 22, the distance between the portion of the upper surface of the heat conductor 14 exposed to the housing space Rc in the housing portion 11 c and the bottom surface of the cultivation container 5 can be separated. Thereby, the degree of the heating or cooling of the water in the cultivation container 5 by the heat conductor 14 can be adjusted. By changing the thickness of the shielding material 22, the distance between the portion of the top surface of the heat conductor 14 exposed to the housing space Rc in the housing portion 11 c and the bottom surface of the cultivation container 5 can be changed. That is, by changing the thickness of the shielding material 22, the degree of heating or cooling of the water in the cultivation container 5 can be adjusted.

  In addition, in this embodiment, the accommodating part 11a accommodates the cultivation container 5 directly as it is, the accommodating part 11b accommodates the cultivation container 5 in the state in which the spacer member 21 is installed, and the accommodating part 11c includes the shielding material 22. Although the cultivation container 5 was accommodated in the installed state, the installation location of the spacer member 21 and the shielding material 22 is not limited. That is, the spacer member 21 or the shielding material 22 may be installed in the housing portion 11a, the shielding material 22 may be installed in the housing portion 11b, or the spacer member 21 may be installed in the housing portion 11c. Moreover, you may accommodate the cultivation container 5 directly in the accommodating parts 11b and 11c. Moreover, for example, the accommodating portions 11 a to 11 c may accommodate the cultivation container 5 in a state where both the spacer member 21 and the shielding material 22 are installed.

  Next, the Example at the time of operating the Peltier device 15a and measuring the temperature of the water in the cultivation container 5 is described. Here, as shown in FIG. 5, the cultivation container 5 was directly accommodated in the accommodation part 11a. The cultivation container 5 was accommodated in the accommodation part 11b in a state where the spacer member 21 was installed. As the spacer member 21, a member made of polypropylene resin having a thickness of 5 mm was used. The cultivation container 5 was accommodated in the accommodation part 11c in a state where the spacer member 21 and the shielding material 22 were installed. As the spacer member 21, a member made of polypropylene resin having a thickness of 5 mm was used, and as the shielding material 22, a foamed polystyrene plate material having a thickness of 5 mm was used. Each cultivation container 5 was filled with 1.5 liters of water. Further, the Peltier element 15a of the first heat source 15 was operated so that the temperature of the heat conductor 14 was maintained at a predetermined temperature. The first heat source 15 can keep the temperature of the heat conductor 14 constant, for example, by measuring the temperature of the heat conductor 14 and performing feedback control.

  When the temperature of the heat conductor 14 is stabilized by operating the Peltier element 15a, the temperature of the water in the cultivation container 5 installed in the accommodating portion 11a (the spacer member 21 and the shielding material 22: none) is 18.5 ° C. there were. The temperature of the water in the cultivation container 5 installed in the accommodating portion 11b (spacer member 21: present) was 20.0 ° C. The temperature of the water in the cultivation container 5 installed in the accommodating part 11c (spacer member 21 and shielding material 22: present) was 20.0 degrees. The outside temperature at this time was 26.0 degrees.

  Thus, the temperature of the water in the cultivation container 5 becomes high compared with the case where the spacer member 21 and the shielding material 22 are not installed by using the spacer member 21 or using the spacer member 21 and the shielding material 22. It was.

  When 7 hours have passed since the temperature of the heat conductor 14 is stabilized, the temperature of the water in the cultivation container 5 installed in the accommodating portion 11a (the spacer member 21 and the shielding material 22: none) is 18.5 ° C. there were. The temperature of the water in the cultivation container 5 installed in the accommodating portion 11b (spacer member 21: present) was 19.5 ° C. The temperature of the water in the cultivation container 5 installed in the accommodating part 11c (spacer member 21 and shielding material 22: present) was 20.1 degrees. The outside temperature at this time was 24.6 degrees.

  Thus, even if time passed, the temperature of the water in the cultivation container 5 hardly changed. Moreover, since the temperature of the water in the cultivation container 5 installed in the accommodating part 11a (the spacer member 21 and the shielding material 22: none) does not change even if the outside air temperature changes, the temperature of the water in the cultivation container 5 is It was found that it was not affected by outside air temperature changes. It turned out that the cooling performance of the water in the cultivation container 5 can be changed by using the spacer member 21 or using the spacer member 21 and the shielding material 22 compared with the case where these are not used.

  This embodiment is configured as described above, and in this temperature control device 4, the first heat source 15 is accommodated in the first heat source accommodating portion 11 d, thereby cultivating the respective cultivations accommodated in the plurality of accommodating portions 11 a to 11 c. Heat generated by the first heat source 15 can be transferred to the container 5 via the heat conductor 14. Moreover, accommodating part 11a-11c has the shape which dents the main-body part 11 concavely toward the heat conductor 14 so that the external shape of the cultivation container 5 may be followed. For this reason, while covering the cultivation container 5 accommodated in accommodation part 11a-11c with the main-body part 11 which is a heat insulating material so that it may adapt to the external shape of the cultivation container 5, it is from the heat conductor 14 to several cultivation containers 5. Can transfer heat. It is accommodated by surrounding the cultivation container 5 so as to follow the outer shape of the cultivation container 5 by the main body part 11 which is a heat insulating material (the entire outer surface of the cultivation container 5 is in a state of being closely fitted to the concave shape of the heat insulation material). Even if it is a case where the upper part of the parts 11a-11c is opening (the opening part is not covered with a cover etc.), it can suppress that the water in the cultivation container 5 receives the influence of the temperature change of external air. Thereby, the temperature of these cultivation containers 5 can be adjusted efficiently, accommodating a plurality of cultivation containers 5.

  The upper surface of the heat conductor 14 is exposed in the accommodation spaces Ra to Rc. In this case, for example, heat can be efficiently transferred from the heat conductor 14 to the cultivation container 5 like the cultivation container 5 accommodated in the accommodation portion 11a shown in FIG.

  For example, like the accommodating part 11c shown in FIG. 4, the heat quantity transmitted from the heat conductor 14 to the cultivation container 5 can be suppressed by arrange | positioning the shielding material 22 in the accommodating part 11c. Thereby, the performance of heating or cooling can be changed by installing the shielding member 22.

  For example, like the accommodating part 11b shown in FIG. 4, the cultivation container 5 and the heat conductor 14 can be separated by arrange | positioning the spacer member 21 in the accommodating part 11b. Thereby, the calorie | heat amount transmitted to the cultivation container 5 from the heat conductor 14 can be suppressed. Therefore, the performance of heating or cooling can be changed by installing the spacer member 21.

  The first heat source 15 performs heating and cooling by operating the Peltier element 15a. In this case, the cultivation container 5 can be easily heated or cooled only by supplying electric power to the Peltier element 15a.

  By using a phenol resin, a polystyrene resin, a phenol resin foam, a polystyrene resin foam, or the like as the main body 11, the bottom 12, and the lid 13, the main body 11 or the like can be easily formed. Moreover, the heat insulation performance of the main body part 11, the bottom part 12, and the cover part 13 can be improved.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, the temperature control device 4 shown in FIGS. 2 and 3 is configured to include a main body 11, a bottom 12, a lid 13, a heat conductor 14, and a first heat source 15. Although not shown in the embodiment, the temperature control device 4 does not have the first heat source 15 and can be an external connection method. That is, the first heat source 15 can be configured to be connected to the heat conductor 14 from a connection portion provided in the temperature adjustment device 4.
Moreover, in other embodiment of this invention, although not shown in figure, as for the some accommodating parts 11a-11c provided in the main-body part 11, and the accommodating part 11d for 1st heat sources, the main-body part 11 is the heat conductor 14. The first heat source housing may have a shape that is recessed in a concave shape, and a state in which the upper surface of the heat conductor 14 is exposed to the housing spaces Ra to Rd, and a shape that is common to the housing portions 11a to 11c. It is also possible to provide the first heat source 15 in the part 11d.
Although not shown in the other embodiment of the present invention, the first heat source 15 provided in the first heat source housing portion 11d is heated or cooled by operating the Peltier element 15a. If heating or cooling is possible, for example, another heat source such as ice water, hot water, or a refrigerant may be provided in the first heat source housing 11d as the first heat source 15 instead of the Peltier element 15a.
In any of the above-described embodiments, the housing part in which the heat source (first heat source 15) is disposed is described as the first heat source housing part 11d. However, the present invention is not limited to this. A heat source (first heat source 15) may be arranged in any of the plurality of housing portions (11a to 11d) provided in the housing.

  Furthermore, the heat source is not limited to one first heat source 15, and a plurality of heat sources may be arranged in separate accommodating portions. For example, in other embodiment of this invention, you may install another heat source in accommodating part 11a-11c besides heating or cooling the heat conductor 14 only with the 1st heat source 15. FIG. FIG. 6 shows a case where a container 30 containing ice water (another heat source) X as a second heat source is installed in the accommodation part 11b (another heat source accommodation part). As shown in FIG. 6, ice water X is accommodated in the container 30. The container 30 is placed on a portion of the upper surface of the heat conductor 14 that is exposed to the accommodation space (other heat source accommodation space) Rb in the accommodation portion 11b. Thereby, in addition to the cooling of the heat conductor 14 by the first heat source 15, the heat conductor 14 can be efficiently cooled by the ice water X in the container 30.

  Instead of the container 30 in which the ice water X is accommodated, the container 30 in which hot water (other heat source) is accommodated may be disposed in the accommodating portion 11b. In this case, in addition to the heating of the heat conductor 14 by the first heat source 15, the heat conductor 14 can be efficiently heated by the hot water in the container 30. Moreover, when installing the container 30 in which the ice water X etc. were accommodated in the accommodating part 11b, it is good also considering the 1st heat source 15 as a halt condition. In this case, the water in the cultivation container 5 can be heated or cooled using the ice water X or hot water as a heat source without using the first heat source 15.

  In FIG. 6, although the container 30 was installed in the accommodating part 11b, the place which installs the container 30 is not limited to the accommodating part 11b. In FIG. 6, the container 30 is installed in the storage unit 11 b that can store the cultivation container 5, but another dedicated heat source storage unit may be provided to install the container 30. The other heat source housing portion is formed by forming the main body portion 11 in a concave shape toward the heat conductor 14 and exposing the upper surface of the heat conductor 14 in the same manner as the housing portion 11b and the like. be able to.

  Here, the temperature change of the water in the cultivation container 5 at the time of installing the container 30 which accommodated the ice water X in the accommodating part 11b as shown in FIG. 6 is demonstrated. Here, the cultivation containers 5 were directly accommodated in the accommodating portions 11a and 11c (as they were, without interposing the spacer member 21 and the shielding material 22). Each cultivation container 5 was filled with 1.5 liters of water. Moreover, the 1st heat source 15 was made into the stop state. When the container 30 was placed on the upper surface of the heat conductor 14 in the housing part 11b, the temperature of the water in the cultivation container 5 installed in the housing part 11a was 24.1 ° C. The temperature of the water in the cultivation container 5 installed in the accommodating part 11c was 25.0 degree | times. Of the upper surface of the heat conductor 14, the temperature of the portion exposed to the housing space Rb in the housing portion 11b was 11.2 ° C. The outside temperature at this time was 20.0 degrees.

  When 30 minutes passed after installing the container 30 in the accommodating part 11b, the temperature of the water in the cultivation container 5 installed in the accommodating part 11a was 23.0 degreeC. The temperature of the water in the cultivation container 5 installed in the accommodating part 11c was 24.0 degree | times. The temperature of the part exposed to the accommodation space Rb in the accommodation part 11b in the upper surface of the heat conductor 14 was 12.7 ° C. The outside temperature at this time was 20.0 degrees.

  Thus, when 30 minutes have passed since the container 30 in which the ice water X is accommodated in the accommodating part 11b, the temperature of the water in the cultivation container 5 accommodated in the accommodating parts 11a and 11c is about 1 ° C. It became low. The temperature of the heat conductor 14 on which the container 30 was placed rose by 1.5 ° C. Thus, by installing the container 30 in which the ice water X is accommodated in the accommodating part 11b, heat is taken from the water in the cultivation container 5 accommodated in the other accommodating parts 11a and 11c, and the heat is transmitted ( Endothermic). Therefore, in addition to using the first heat source 15, the water in the cultivation container 5 accommodated in the accommodating portions 11a and 11c can be cooled by installing ice water or the like in the accommodating portion 11b.

  Moreover, in other embodiment of this invention, like the accommodating parts 11e and 11f provided in the main-body part 11A of the temperature control apparatus 4A shown in FIG. 7, the accommodation space Re in the accommodating part 11e and the accommodating part 11f The upper surface of the heat conductor 14 may not be exposed in the accommodation space Rf. The performance of heating or cooling can be changed depending on the distance between the bottoms of the accommodating portions 11e and 11f and the heat conductor 14. In the example illustrated in FIG. 7, the distance between the bottom portion of the housing portion 11 e and the heat conductor 14 is shorter than the distance between the bottom portion of the housing portion 11 f and the heat conductor 14. Thereby, the direction of the cultivation container 5 accommodated in the accommodating part 11f is hard to receive the influence of the heat | fever of the heat conductor 14 rather than the cultivation container 5 accommodated in the accommodating part 11e.

  In other embodiment of this invention, although the plant cultivation container 5 was accommodated in accommodating part 11a-11c as a to-be-contained object, to-be-contained objects other than the cultivation container 5 may be accommodated. For example, you may accommodate a drink bottle, a foodstuff, a water tank, etc. as a to-be-contained object. Also in this case, the main body portion 11 is formed with a housing portion having a shape that is recessed toward the heat conductor 14 along the outer shape of the object to be housed.

Moreover, in other embodiment of this invention, like the temperature control apparatus 4B shown in FIG. 8, the opening part of the accommodating parts 11g and 11h formed in the main-body part 11B, and the opening of 11 d of accommodation parts for 1st heat sources. You may provide the cover (cover for to-be-contained objects / cover for 1st heat sources) 16 which covers a part. In this case, it is possible to suppress the objects to be accommodated (for example, foods that require cooling) accommodated in the accommodating portions 11g and 11h from being affected by the temperature of the outside air.
In this case, since the cover 16 that covers the opening of the first heat source accommodating portion 11d is provided, the entire outer surface of the accommodated object is thermally insulated when the accommodated object is accommodated in the accommodating portions 11g and 11h. Even if the shape of the material is not exactly fitted into the concave shape (even if there is a gap between the heat insulating material), the temperature of the object can be adjusted.
Further, when a container in which hot water or ice water is accommodated instead of the first heat source 15 is installed in the first heat source accommodating portion 11d, the cover 16 is provided so that the hot water or ice water or the like accommodated in the container is outside air. It is possible to suppress the influence of the temperature change. Thereby, the to-be-contained object accommodated in the accommodating parts 11g and 11h can be heated or cooled for a long time. In addition, a cover (cover for the object to be stored) that covers the openings of the storage parts 11g and 11h that store the objects to be stored, and a cover (a cover for the first heat source) that covers the opening of the storage part 11d for the first heat source. You may form separately.

  Although the heat conductor 14 is sandwiched between the main body portion 11 and the bottom portion 12, the heat conductor 14 can be included in the heat insulating material and has a shape that is recessed toward the heat conductor 14. As long as it can be formed, the heat insulating material such as the main body 11 may have another configuration. For example, the main body 11 and the bottom 12 may be integrated. Further, a cover having a shape along the outer shape of the main body 11 may be provided on the main body 11 or the like.

  Although the Peltier element 15a is thermally connected to the upper surface of the heat conductor 14, the position where the Peltier element 15a is connected to the heat conductor 14 is not limited to the upper surface.
