Embodiments for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same reference numerals are given to the same drawings throughout, and duplicate explanations are omitted.

[0014] FIG. 1 is an external view of an apartment building in which the cultivation system according to the present embodiment is installed.

[0015] The apartment building 1 is a three-story building and has a plurality of living rooms. The apartment building 1 may be an empty house without occupants, and the indoor cultivation system 100 according to the present embodiment is installed for the purpose of effectively using the empty house.

[0016] The apartment building 1 is provided with a light guiding unit for guiding outdoor natural light into the interior of the house. The light guiding unit includes a light collecting plate (not shown) installed on the roof of the apartment building 1 and a light guiding tube 71 for guiding light from the light collecting plate into each living room.

[0017] FIG. 2 is a plan view of an apartment building in which the indoor cultivation system according to the present embodiment is installed. FIGS. 3 and 4 are schematic diagrams showing the isolation room.

[0018] As shown in Fig. 2, the apartment house 1 is provided with four living rooms 2a, 2b, 2c, and 2d adjacent to each other with walls therebetween. In the living spaces of these multiple living rooms 2b, 2c, and 2d, isolation rooms 10b and 10dc are installed. Since the isolation rooms 10b, 10c, and 10d installed in the living rooms 2b, 2c, and 2d have the same configuration, hereinafter, the isolation room 10d installed in the living room 2d will be taken as an example for explanation, but the following explanation also applies equally to the isolation rooms 10b and 10c installed in the living rooms 2b and 2c.

[0019] In Fig. 3, for the convenience of explanation, the ceiling of the living room 2d is not shown, and the isolation room 10d installed in the living room 2d is shown. Also in Fig. 4, for the convenience of explanation, the wall of the living room 2d is not shown, and the isolation room 10d installed in the living room 2d is shown.

[0020] As shown in Figs. 3 and 4, the isolation room 10d is formed by partitioning the living space of the living room 2d and the internal space of the isolation room 10d by a partition wall 11. The partition wall 11 may be made of a translucent sheet, for example, a vinyl chloride sheet or the like.

[0021] It is desirable that the volume of the internal space of the isolation room 10d is 80% or more of the total volume of the living space of the living room 2d. 80% is an example where it is possible to achieve both ventilation of the living room and effective utilization of the living space by taking in outside air into the living space once and then taking it into the interior of the isolation room 10d.

[0022] Inside the apartment house 1, a main water supply pipe 20 communicating across the living rooms 2a, 2b, 2c, and 2d is installed. Inside the living room 2d, a branch water supply pipe 21 for supplying water from the main water supply pipe 20 to the interior of the isolation room 10d is installed. The upper liquid fertilizer tank 22 is connected to one end of the main water supply pipe 20. The main water supply pipe 20 is connected to branch water supply pipes 21 for supplying liquid fertilizer to the interiors of the isolation rooms 10b, 10c, and 10d respectively.

[0023] Inside the apartment building 1, a main drain pipe 30 that communicates across the living rooms 2a, 2b, 2c, and 2d is installed. Inside the living room 2d, a branch drain pipe 31 that drains from inside the isolation room 10d toward the main drain pipe 30 is installed.

[0024] Figure 5 is a liquid fertilizer circulation path diagram (water circulation path) of the indoor cultivation system.

[0025] As shown in Figure 5, the living room 2a is equipped with an upper liquid fertilizer tank 22, a lower liquid fertilizer tank 32, a stock solution tank 41 of liquid fertilizer, a liquid fertilizer supply pipe 42, a tap water supply pipe 43, a pump 44, a suction pipe 45, and a control panel 46.

[0026] One end of the main water supply pipe 20 is connected to the upper liquid fertilizer tank 22. In the middle or near the end of the main water supply pipe 20, it is connected to the branch water supply pipes 21 that supply liquid fertilizer to the interiors of the isolation rooms 10b, 10c, and 10d respectively.

[0027] Inside each of the isolation rooms 10b, 10c, and 10d, a plant stand 50 is installed between the branch water supply pipe 21 and the branch drain pipe 31.

[0028] The plant stand 50 is a structure that supports the plants to be cultivated and supplies liquid fertilizer to the plants. During the process where the liquid fertilizer passes through the plant stand 50 from the branch water supply pipe 21 and flows down into the branch drain pipe 31, water supply and fertilization are carried out on the plants.

[0029] A funnel 60 is installed at the lower part of the plant stand 50. The liquid fertilizer that has flowed down from the plant stand 50 is collected by the funnel 60, flows from the funnel 60 into the branch drain pipe 31, and then flows into the lower liquid fertilizer tank 32 through the main drain pipe 30.

[0030] A pump 44 is installed inside the lower liquid fertilizer tank 32. Also, the lower liquid fertilizer tank 32 and the upper liquid fertilizer tank 22 are connected by a suction pipe 45.

[0031] The liquid fertilizer stored in the lower liquid fertilizer tank 32 is discharged from the pump 44 into the suction pipe 45 and flows into the upper liquid fertilizer tank 22 through the suction pipe 45. The liquid fertilizer stored in the upper liquid fertilizer tank 22 is supplied again to the main water supply pipe 20, the branch water supply pipe 21, and the plant stand 50. In this way, a circulation path for the liquid fertilizer is formed.

[0032] Next, the replenishment path for the liquid fertilizer will be described.

[0033] The stock solution tank 41 is connected to the lower liquid fertilizer tank 32 via the liquid fertilizer supply pipe 42. Also, the tap water supply pipe 43 is connected to the lower liquid fertilizer tank 32. The control panel 46 controls the opening and closing or the opening degree adjustment of valves (not shown) respectively installed in the liquid fertilizer supply pipe 42 and the tap water supply pipe 43 according to the remaining amount of the liquid fertilizer in the lower liquid fertilizer tank 32, and executes control for supplying the liquid fertilizer stock solution and the tap water to the lower liquid fertilizer tank 32. Thereby, the lower liquid fertilizer tank 32, and thus the liquid fertilizer circulation path, is replenished with the liquid fertilizer.

[0034] FIG. 6 is an enlarged view of the funnel 60. FIG. 7 is a diagram showing an installation example of the funnel 60.

[0035] The funnel 60 includes a large-diameter cylindrical portion 61, a small-diameter cylindrical portion 62, an inclined surface that extends from the large-diameter cylindrical portion 61 toward the small-diameter cylindrical portion 62, and a tapered cylindrical portion 63 that connects the large-diameter cylindrical portion 61 and the small-diameter cylindrical portion 62.

[0036] As shown in FIG. 7, a plurality of funnels 60 are arranged along the depth direction in FIGS. 3 and 4 at the lower part of the plant stand 50.

[0037] FIG. 8 is an air circulation diagram of each living room.

[0038] The living room spaces of each living room 2b, 2c, 2d are separated into a peripheral space 2s located outside the isolation room 10 by the partition wall 11 and an internal space 10s of the isolation room 10. The partition wall 11 is provided with an indoor air supply pipe 12 that communicates the peripheral space 2s and the internal space 10s of the isolation room 10.

[0039] In addition, an outdoor air supply pipe 13 communicating with the living room space and the outdoor space 3 is provided in the living room 2.

[0040] Furthermore, an exhaust pipe 14 communicating with the internal space of the isolation room 10 and the outdoor space 3 is provided. An exhaust fan 15 for forcibly exhausting air outdoors is installed in the exhaust pipe 14.

[0041] When the exhaust fan 15 rotates, the air in the internal space 10s is exhausted from the exhaust pipe 14 to the outdoor space 3. Therefore, the internal space 10s becomes a negative pressure, and the air in the surrounding space 2s flows into the internal space 10s via the indoor air supply pipe 12. Then, the surrounding space 2s becomes a negative pressure, and the air in the outdoor space 3 flows into the surrounding space 2s via the outdoor air supply pipe 13.

[0042] That is, an air circulation path is formed in which the air in the outdoor space 3 is exhausted to the outdoor space 3 via the outdoor air supply pipe 13, the surrounding space 2s, the indoor air supply pipe 12, the internal space 10s, and the exhaust pipe 14.

[0043] A plant stand 50 is installed in the cultivation space in the isolation room 10 for cultivating plants. Therefore, the humidity in the internal space 10s tends to be higher than that in the outdoor space 3. On the other hand, when the living room space becomes highly humid, condensation may occur indoors or mold may grow, and it is not preferable as the preservation condition of the building structure for the humidity in the room to rise to a humidity suitable for cultivation. According to the present embodiment, the isolation room 10 is formed in the living room space by the partition wall 11, the internal space 10s used as the cultivation space and the surrounding space 2s are separated, and the air in the internal space 10s is corrected and exhausted outdoors, so that the humid air in the internal space 10s can be prevented from filling the living room 2, and the indoor humidity can be suppressed from becoming high.

[0044] FIG. 9 and FIG. 10 are schematic diagrams showing a light guide unit for the isolation room 10.

[0045] As shown in FIGS. 9 and 10, a light guide pipe 71 that guides sunlight navigating on the roof of the building may be introduced into the information of the plant stand 50 in the isolation room 10 of each living room 2b, 2c, 2d. Thereby, in addition to the indoor lighting of each living room 2b, 2c, 2d, sunlight can be introduced into each living room 2b, 2c, 2d, and the growth of plants can be promoted more than in the case of only indoor lighting.

[0046] According to the present embodiment, by forming a large cultivation space in the living room and also forming a liquid fertilizer circulation path and an air circulation path, it is possible to prevent the living room from becoming humid while cultivating plants in the living room. Therefore, it is possible to cultivate plants using more than half of the volume in the living room.

[0047] In addition, in an apartment building, while forming isolation rooms in each of a plurality of living rooms, by sharing a liquid fertilizer circulation path for circulating liquid fertilizer in those isolation rooms, it becomes easier to replenish the liquid fertilizer.

[0048] Furthermore, by allowing sunlight to enter the living room, it is possible to eliminate insufficient lighting and promote the growth of plants.

[0049] Furthermore, by applying this cultivation system to vacant apartment buildings where residents do not gather, although an increase in vacant houses due to population decline is a concern in the future, by providing a cultivation system that can effectively utilize vacant houses, a contribution to the social problem of the increase in vacant houses can be expected.

[0050] Each of the above embodiments does not limit the present invention, and modifications within the scope not departing from the gist of the present invention are included in the scope of rights of the present invention.

[0051] For example, although an apartment building has been described as an example, a single-family house may also be used.

[0052] In addition, in the above, an example of installing a liquid fertilizer circulation path capable of supplying and draining water to a plurality of living rooms has been given. As another example, an isolation room may be installed in one living room, and the isolation room may be provided with a liquid fertilizer circulation path.

[0053] Furthermore, in the above description, the isolation rooms 10 are provided in each of the plurality of living rooms, and these isolation rooms 10 share the main water supply pipe 20, the main drain pipe 30, and the liquid fertilizer replenishment path. However, independent water supply and drainage paths and replenishment paths may be installed in each living room. Thereby, since the types of plants to be cultivated are different, even when the cultivation conditions, such as the type of fertilizer and the amount of water supply, are different, the cultivation conditions can be changed in each room, and it is possible to make both the utilization of vacant houses and the cultivation of multi-variety commodities compatible.

[0054] In addition, the structure, system, program, etc. of the present invention can be variously changed without changing the gist of the present invention.

[0055] For example, it is possible to combine two or more members into one, or conversely, it is also possible to configure and connect one member from two or more other members.

[0056] In addition, the above-described embodiment is merely one of the best forms at present.

[0057] Also, the control etc. may be controlled by a higher-level control part, or may be controlled by a more terminal control part.

[0058] Also, the control order etc. can be appropriately changed as long as it has a predetermined effect.
