Description

[Technical field]

[0001] The present invention relates to a plant cultivation showcase that is mainly installed indoors and in which plants are cultivated. [Background technology]

[0002] As an apparatus that can be installed indoors to cultivate small-scale plants, there is a plant cultivation showcase equipped with a case, a plurality of vertical shelves installed in the case, a hydroponic cultivation mechanism, an air conditioning mechanism, and a light source. The plant cultivation showcase can be installed indoors anywhere, as long as it is a relatively small one that is appropriately installed in a place that is visible to general customers, such as a retail store such as a greengrocer or fruit store, a department store, a supermarket, or a commercial facility, a restaurant, a lodging facility, or an exhibition hall. By installing such a plant cultivation showcase, it can be useful for improving customer satisfaction by not only making it a topic of conversation and eye-catching, but also giving a sense of security about the vegetables provided. For example, Patent Document 1 discloses a plant cultivation showcase in which the case itself is translucent and the plants inside can be seen.

[0003] The plant cultivation showcase of Patent Document 1 includes a base in which the main part of the hydroponic cultivation mechanism and the like are built, and a storage section that is partitioned by an exterior covering the upper part of the base and is air-conditioned by an air-conditioning mechanism. The side of the exterior section is made of transparent glass doors, allowing the plants growing inside the storage section to be observed. In addition, lighting devices are installed above each of the multiple shelves, providing illumination at an appropriate illuminance for hydroponic cultivation. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5767506 (page 4, figure 3) Summary of the Invention [Problem to be solved by the invention]

[0005] In the plant cultivation showcase of Patent Document 1, the illuminance is appropriately adjusted by the lighting device to illuminate the plants, so that the growth of the plants can be appropriately managed. Here, many plants have the ability of photoperiodism to sense the length of the day, and for example, there are short-day plants that sense the shortening of the days due to the change of seasons, in other words, plants that tend to flower when the length of the dark period is longer than the critical dark period, and long-day plants that tend to flower when the dark period is shorter than the critical dark period. The plant cultivation showcase described above is installed indoors in a place where it is visible to general customers, and in the case of a store, for example, the light from the lighting device in the store will enter the storage unit through the glass door that forms the exterior during the store's business hours. Therefore, there was a problem that the store's business hours, i.e., the time when the lighting device in the store is turned off, do not match the optimal dark period for plants whose growth is greatly affected by photoperiodism, and there is a risk of adversely affecting the growth of such plants, making it unsuitable for cultivation of such plants.

[0006] The present invention has been made with attention to such problems, and has an object to provide a plant cultivation showcase capable of cultivating plants whose growth is significantly affected by photoperiodism indoors. [Means for solving the problem]

[0007] In order to solve the above problems, the plant cultivation showcase of the present invention comprises: A plant cultivation showcase comprising a base and a storage section in which a plurality of shelves are arranged above and below, the storage section being partitioned by an exterior part having transparency on a side part covering the upper part of the base, The light-shielding cover is characterized in that it is capable of covering the side surface of the exterior part along the outer surface shape. According to this feature, by covering the side portions of the transparent exterior portion with the light-shielding cover at the appropriate time, the inside of the storage portion can be made dark regardless of the illuminance of the indoor space, thereby ensuring an optimal dark period for plants, whose growth is greatly affected by photoperiodism, and providing an appropriate cultivation environment for their growth.

[0008] The light-shielding cover is characterized in that, when not in use, it is wound up and stored in a winding unit having a biasing means. This feature allows the light-shielding cover to be stored neatly when not in use.

[0009] The exterior portion has a substantially rectangular parallelepiped shape, and the winding unit is characterized in that the light-shielding cover is arranged so as to be able to cover the four side surfaces of the exterior portion individually. According to this feature, the light-shielding cover can be easily deployed and stored, and the amount of light entering the storage section from outside can be adjusted.

[0010] The winding unit, which houses a light-shielding cover that covers one pair of opposing side portions of the exterior portion, is arranged on the top side of the exterior portion, and the winding unit, which houses a light-shielding cover that covers the other pair of opposing side portions of the exterior portion, is arranged on the base side. According to this feature, the winding units that store adjacent light-shielding covers are positioned at different positions in the vertical direction so as not to interfere with each other, and therefore the light-shielding covers can be formed as large as possible in the horizontal direction to reliably cover the side portions of the exterior part.

[0011] The winding unit on one of the pair of side sections is built into the top surface of the exterior part, and a grip portion at the tip of the light-shielding cover protrudes from a slit formed in the top surface and can be pulled out, The winding unit on the other pair of side portions is built into the base, and is characterized in that the grip portion at the tip of the light-shielding cover protrudes from a slit formed in the base and can be pulled out. According to this feature, when not in use, the light-shielding cover is stored in the top surface or base of the exterior together with the winding unit, resulting in an aesthetically pleasing appearance.

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A plant cultivation showcase according to an embodiment of the present invention will be described below. EXAMPLES

[0014] A plant cultivation showcase according to an embodiment will be described with reference to Fig. 1 to Fig. 6. In the following description, the depth direction of the paper surface of Fig. 2 will be the front and rear sides of the plant cultivation showcase, and the left and right sides of the paper surface will be the left and right sides.

[0015] The plant cultivation showcase according to the present invention is appropriately installed in a place where people can see it, such as a greengrocer or fruit shop, a department store, a supermarket, a retail store such as a commercial facility, a restaurant, a lodging facility, an exhibition hall, an office, etc. The plant cultivation showcase can be powered from a 100V AC power outlet, for example, and is relatively small in external dimensions, with a length of 300 cm or less, a width of 100 cm or less, and a height of 300 cm or less, so that it can be installed indoors anywhere. Installing such a plant cultivation showcase can be useful for improving customer satisfaction, such as by creating a buzz and catching the eye, and by providing a sense of security about the vegetables provided.

[0016] The plant cultivation showcase is basically designed for hydroponic cultivation, and edible plants such as vegetables and fruits, as well as fresh flowers (hereinafter simply referred to as "plants") are displayed with their roots attached on the shelves described below. The plant cultivation showcase is a so-called fully controlled type, where plants are cultivated in a closed environment without using sunlight, and by controlling the plant growth environment (light, temperature, humidity, nutrients, water, etc.), cultivation that allows for planned production throughout the year can be carried out.

[0017] 1, the plant cultivation showcase 1 includes a base 2 in which the main part of the hydroponic cultivation mechanism and the like are built, and a storage section 4 which is partitioned by an exterior part 3 that covers the upper part of the base 2 and is air-conditioned by an air-conditioning mechanism. The storage section 4 is provided with shelf parts 5A to 5C in multiple levels, one above the other.

[0018] The base 2 is composed of a pedestal portion 6 and a cover member 7 surrounding the four side surfaces of the pedestal portion 6, and has a hollow space inside. As shown in FIG. 4 showing the internal structural materials of the plant cultivation showcase 1, the pedestal portion 6 is composed of a rectangular support surface portion 6a in a plan view and a pair of legs 6b spaced apart in the short direction of the support surface portion 6a. An insulating plate 15 is placed on the support surface portion 6a of the pedestal portion 6, and this insulating plate 15 constitutes the upper surface of the base 2. Although not shown here, the insulating plate 15 is formed with an insulating layer inside by injecting and foaming a foamable resin between a hard upper wall material and a hard lower wall material supported so as to form an appropriate gap between them.

[0019] In the hollow space of the base 2, the main part of the hydroponic cultivation mechanism, a control device, a power tap, etc. (not shown) are arranged. In the plant cultivation showcase 1, an air conditioning mechanism is used to manage the temperature and humidity in the storage section 4, a hydroponic cultivation mechanism is used for nutrients and moisture in the shelves 5A to 5C, and lighting devices 16 (see Figs. 2 and 3) are arranged on each of the shelves 5A to 5C, and these air conditioning mechanism, hydroponic cultivation mechanism, and lighting devices 16 are controlled by a control device to be in an optimal state for plant growth. A carbon dioxide generator capable of changing the carbon dioxide concentration may be installed under the control of the control device.

[0020] A rectangular parallelepiped frame 8 is disposed and fixed on the upper surface of the base 2 (the upper surface of the heat insulating plate 15), and the weight of the frame 8 is supported by the base 2. The frame 8 has four vertical rods 9 extending in the up-down direction and horizontal rods 10 connecting adjacent vertical rods 9 in the short direction, and further has a pair of left and right support rods 11, 11 connecting the horizontal rods 10 facing each other in the front-rear direction. The pair of left and right support rods 11, 11 form a shelf support portion that supports a container 12 described later.

[0021] The container 12 is a bottomed tray that opens at the top, and a sufficient amount of culture solution necessary for cultivation constantly flows through it. This culture solution is circulated by a circulation device (not shown) that constitutes the hydroponic cultivation mechanism, so that fresh culture solution is always supplied to the plants.

[0022] The pair of front and rear side sections 20 are made up of two sliding doors 20A, 20B, one on each side. These sliding doors 20A, 20B are made up of a transparent glass panel 20c and a frame 20d. In this way, the side section 20 is mainly transparent, and the inside of the storage section 4 can be easily observed through the transparent glass panel 20c.

[0023] The pair of left and right side sections 21 are composed of a metal plate 21d and a glass panel 21c which is a transparent window section that closes an opening 21e formed in the plate 21d. The opening area of ​​the opening 21e is larger than the surface area of ​​the plate 21d, and the side sections 21 are mainly transparent, making it easy to observe the inside of the storage section 4 through the transparent window section.

[0024] The top surface 19 is formed into a bottomless box shape by bending a metal plate, and the bottom part is formed by an insulating plate 19b having the same structure as the separate insulating plate 15, forming a thin, hollow box. The top surface 19 is attached so as to close the upper opening of the storage section 4, which is surrounded by a pair of front and rear side sections 20 and a pair of left and right side sections 21. A rail section (not shown here) is formed on the lower part of the edge of the top surface 19 along the pair of front and rear side sections 20. A similar rail section is also formed on the base 2 side, and the two sliding doors 20A and 20B that constitute the side section 20 are attached to be movable on the double sliding surfaces by these upper and lower rail sections.

[0025] The air conditioning mechanism is a well-known structure and will not be described in detail in the drawings, but it has a main body 25 on the storage unit 4 side which performs the air conditioning, and a control unit which controls the refrigerant. The control unit has a condenser, a compressor, and a pressure reducer, which are built into the base 2. Although not shown here, the main body 25 has an evaporator and a fan built in, and the evaporator on the main body 25 side and the condenser on the control unit side are connected via a compressor and pressure reducer by pipes not shown.

[0026] As shown in FIG. 1, the intake port 30 is disposed facing the side of the evaporator 26, and the air inside the storage section 4 drawn in from the intake port 30 on the side of the housing 28 by the fan 27 is cooled by the evaporator 26 and blown out into the storage section 4 from the air outlet 29 above the housing 28.

[0027] As shown in Fig. 5, the plant cultivation showcase 1 is provided with shading devices 40A, 40B that can cover along the outer surface shape of the side sections 20, 21 of the exterior section 3. In detail, the front shading device 40A covers the front side section 20, the rear shading device 40A not visible in Fig. 5 covers the rear side section 20, the left shading device 40B not visible in Fig. 5 covers the left side section 21, and the right shading device 40B covers the right side section 21, and they are configured separately for each of the four sides of the exterior section 3. Hereinafter, only the front shading device 40A will be described since the front and rear shading devices 40A have the same configuration. The same applies to the left and right shading devices 40B.

[0028] The shading device 40A includes a shading cover 41A capable of covering the glass panel 20c (see FIG. 1) on the side surface 20 of the exterior part 3, a winding unit 42A capable of winding up and storing the shading cover 41A, and a support bar 43A long in the left-right direction attached to the front edge of the shading cover 41A. A grip part 40c is attached to the center part in the longitudinal direction of the support bar 43A.

[0029] Similarly, the shading device 40B includes a shading cover 41B capable of covering the glass panel 21c (see FIG. 1) on the side surface 21 of the exterior part 3, a winding unit 42B capable of winding up and storing the shading cover 41B, and a support bar 43B long in the front-rear direction attached to the front edge of the shading cover 41B. A grip part 40c is attached to the longitudinal center of the support bar 43B.

[0030] 6, the winding unit 42A of the light shielding device 40A includes a winding pipe 44, a rotating shaft 44a protruding outward from both the left and right ends of the winding pipe 44, and a bracket 45 having bearings for rotatably supporting the left and right rotating shafts 44a, and the light shielding cover 41A is wound around the winding pipe 44. The winding pipe 44 is biased by a torsion spring (not shown) or the like, so that the light shielding cover 41A is constantly biased in the winding direction, that is, the direction of the winding unit 42A. The winding unit 42B of the light shielding device 40B has a similar configuration, and therefore a description thereof will be omitted.

[0031] The winding unit 42A of the light blocking device 40A is built into the top surface 19 of the exterior 3. In detail, inside the top surface 19, a support rod 50 is fixed between an upper plate 19a constituting the top surface 19 and a heat insulating plate 19b spaced downward along the side extending to the left and right where the side surface portion 20 of the top surface 19 is located. Brackets 45 are fixed to the outer surfaces 50a of both ends in the longitudinal direction of the support rod 50. The winding unit 42A is supported between these brackets 45, 45. The top surface plate 19a constituting the top surface 19 is formed to have a smaller front-to-rear width than the heat insulating plate 19b, and a cover member 19c extending in the longitudinal direction is attached above the top surface plate 19a so as to cover the winding unit 42A and the brackets 45, 45.

[0032] The winding unit 42B of the light blocking device 40B is built into the base 2. More specifically, inside the base 2, a crank-shaped support rod 46 is fixed along an edge extending from front to back where the side surface portion 21 of the support surface portion 6a of the pedestal portion 6 is located. Brackets 45 are fixed to outer surfaces 46a of the longitudinal ends of the support rod 46, and the winding unit 42B is supported between these brackets 45, 45. In other words, the winding unit 42B is stored below the support surface portion 6a.

[0033] The shading cover 41A of the shading device 40A is a cover that blocks or reduces light that enters the storage unit 4 from the outside of the plant cultivation showcase 1 through the glass panel 20c of the side surface portion 20, and is formed of, for example, a black mesh, and its left-right dimension is formed to be equal to or slightly larger than the left-right width of the glass panel 20c. Similarly, the shading cover 41B of the shading device 40B is also formed of, for example, a black mesh that blocks or reduces light that enters the storage unit 4 from the outside of the plant cultivation showcase 1 through the glass panel 21c of the side surface portion 21, and its left-right dimension is formed to be equal to or slightly larger than the left-right width of the glass panel 21c.

[0034] The support bar 43A of the shading device 40A is made of, for example, synthetic resin material, and has a long magnet 47 fixed thereto along the left-right direction. This magnet 47 is adapted to be attracted to the outer surface of the cover member 7 of the base 2, which is made of a magnetic material. In this way, the magnet 47 and the cover member 7 of the base 2 constitute a locking means.

[0035] Further, a long magnet 47 provided on support bar 43B of shading device 40B, which has a structure similar to that of support bar 43A of shading device 40A, is adapted to be attracted to the upper surface of top surface 19 of exterior part 3 made of a magnetic material. In this manner, magnet 47 and top surface 19 constitute a locking means.

[0036] It is preferable to make the magnet 47 long because this allows the entire longitudinal direction of the support bars 43A, 43B to be in close contact with the base 2 or the top surface 19, but it is also possible to affix only to the center of the longitudinal direction of the support bars 43A, 43B, or to affix a plurality of magnets at regular intervals. Also, contrary to the above, for example, a magnet may be affixed to the base 2 or top surface 19 side and a magnetic metal plate or the like may be affixed to the support bars 43A, 43B side, or the entire support bars 43A, 43B may be made of a magnetic material and the metal plate may be omitted.

[0037] As shown in Figure 6, the winding unit 42A of the shading device 40A is built into the top surface 19 of the exterior part 3, and when the winding of the shading cover 41A is completed, the gripping portion 40c attached to the tip support bar 43A protrudes a predetermined length from a slit 48 formed in the top surface 19.

[0038] In detail, the insulating plate 19b constituting the top surface portion 19 and the cover member 19c also constituting the top surface portion 19 are vertically spaced a predetermined distance apart to form a slit 48, the insulating plate 19b has a protruding portion 48a protruding upward at the back side of the slit 48, and when the rear end of the support bar 43A of the shading device 40A abuts against the protruding portion 48a within the slit 48, further winding is restricted. In other words, this protruding portion 48a functions as a restricting portion.

[0039] In addition, the light-shielding cover 41A is pulled downward along the lower edge 48b of the slit 48 in a direction perpendicular to the depth direction of the slit 48, and is pressed against the lower edge 48b of the slit 48 when the magnet 47 of the support bar 43A at the tip of the light-shielding cover 41A is attracted to the base 2. Therefore, the light-shielding cover 41A can be reliably brought close to the outer surface of the side surface portion 21, and the light-shielding effect is high.

[0040] As shown in FIG. 7, the winding unit 42B of the shading device 40B is built into the base 2, and when winding of the shading cover 41B is complete, the gripping portion 40c attached to the tip support bar 43B protrudes a predetermined length from a slit 49 formed on the side of the base 2.

[0041] More specifically, the surface of the cover member 7 of the base 2 corresponding to the side surface 21 is composed of a cover main body 7a and a blocking member 7b. The cover main body 7a is formed with an opening at the upper end, and a separate blocking member 7b is fixed to the support surface 6a of the base 6 by a fixing means (not shown) so as to fill the opening (see FIG. 3). The blocking member 7b and the cover main body 7a are vertically spaced a predetermined distance apart to form a slit 49.

[0042] The blocking member 7b has a bottom surface portion 49a that protrudes downward at the back side of the slit 49, and when the rear end of the support bar 43B of the light blocking device 40B abuts against the bottom surface portion 49a inside the slit 49, further winding is restricted. In this manner, the bottom surface portion 49a functions as a restricting portion.

[0043] In addition, the light-shielding cover 41B is pulled out upward along the upper edge 49b of the slit 49 in a direction perpendicular to the depth direction of the slit 49, and is pressed against the upper edge 49b of the slit 49 when the magnet 47 of the support bar 43B at the tip of the light-shielding cover 41B is attracted to the top surface portion 19. Therefore, the light-shielding cover 41B can be reliably brought close to the outer surface of the side surface portion 21, resulting in a high light-shielding effect.

[0044] In this way, the plant cultivation showcase 1 has the shading covers 41A, 41B capable of covering the side parts 20, 21 of the exterior part 3 along the outer surface shape, and by appropriately covering the side parts 20, 21 of the transparent exterior part 3 with these shading covers 41A, 41B, the inside of the storage part 4 can be darkened regardless of the illuminance of the indoor space in which the plant cultivation showcase 1 is installed or the external light, and the optimum dark period for plants whose growth is greatly affected by photoperiodism, such as strawberries, can be secured, and a suitable cultivation environment for growth can be obtained. In particular, when the plant cultivation showcase 1 is installed in a store, even if the store's business hours and the dark period suitable for the plants to be cultivated are not aligned, the shading covers 41A, 41B can appropriately block the light from the lighting device in the store, and the inside of the storage part 4 can be maintained in a good cultivation environment.

[0045] When not in use, the light-shielding covers 41A and 41B are wound up by winding units 42A and 42B having biasing means, allowing the covers to be stored neatly.

[0046] Further, the winding units 42A, 42B are arranged so that the light-shielding covers 41A, 41B can cover each of the four side surfaces 20, 21 of the substantially rectangular exterior part 3. This makes it easy to unfold and retract the light-shielding covers 41A, 41B, and also makes it possible to adjust the amount of light entering the storage part 4 from the outside.

[0047] Further, the winding unit 42A that stores the light-shielding cover 41A that covers the pair of opposing front and rear side portions 20, 20 of the exterior portion 3 is disposed on the top surface portion 19 side of the exterior portion 3 and is adapted to pull the light-shielding cover 41A downward. The winding unit 42B that stores the light-shielding cover 41B that covers the pair of opposing left and right side portions 21, 21 of the exterior portion 3 is disposed on the base portion 2 side and is adapted to pull the light-shielding cover 41B upward. According to this, the winding units 42A, 42B that store the adjacent light-shielding covers 41A, 41B are disposed at different positions in the vertical direction, so that both ends of the light-shielding covers 41A, 41B in the width direction do not interfere with each other, and the light-shielding covers 41A, 41B can be formed as large as possible in the horizontal direction to reliably cover the side portions 20, 21 of the exterior portion 3.

[0048] One winding unit 42A is built into the top surface 19 of the exterior, and the other winding unit 42B is built into the base 2, and the light-shielding covers 41A, 41B are stored together with the winding units 42A, 42B in the top surface 19 of the exterior 3 or in the base 2 when not in use, resulting in an aesthetically pleasing appearance. In addition, the gripping parts 40c of each of the light-shielding covers 41A, 41B protrude from the slits 48 or 49 in the stored state, allowing the covers to be easily pulled out.

[0049] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes modifications and additions that do not deviate from the gist of the present invention.

[0050] For example, in the above-mentioned embodiment, the winding units 42A, 42B that house adjacent light-shielding covers 41A, 41B are configured to be arranged at different positions in the vertical direction, but this is not limited to the above, and all of the winding units may be built into one side of the top surface portion 19 or the base portion 2, for example.

[0051] Furthermore, the winding units 42A, 42B that house the light-shielding covers 41A, 41B may be disposed on the outside of the top surface portion 19 and the base portion 2 to facilitate maintenance.

[0052] Further, the light-shielding covers 41A and 41B are not limited to being wound up by the winding units 42A and 42B and stored, but may be, for example, folded and stored.

[0053] The winding units 42A, 42B of the light-shielding covers 41A, 41B may be of a so-called pull-cord type, in which locking and release are repeated every time the winding units are pulled out.

[0054] Further, the locking means for the light shielding covers 41A and 41B is not limited to the configuration using the magnet 47, but may be, for example, a hook or the like.

[0055] Further, the light-shielding covers 41A and 41B are not limited to a black mesh structure, and may be made of, for example, a polarizing film having light-shielding properties.

[0056] Moreover, the light-shielding covers 41A and 41B may be integrally formed across the adjacent side surfaces.

[0057] Moreover, the exterior part 3 is not limited to a rectangular parallelepiped, and may be formed in a polygonal cylindrical shape such as a pentagonal prism in a plan view.

[0058] Furthermore, the location where the plant cultivation showcase 1 is installed is not limited to a place visible to general customers, but may be, for example, the back yard of a restaurant. [Explanation of symbols]
