A predetermined amount is fitted together with the water supply zone 2 through a hole 3a formed on the bottom side of the flowerpot 3. Thereafter, the water supply zone 2 was set in the flower pot 3 by pulling out the water supply zone setting cylinder 1 from above while leaving the lower end of the water supply zone 2 outside the flower pot 3, and the water was stored. The flowerpot 3 is placed on the water receiving tray with a sufficient clearance. Then, the water supply zone 2 sucks water into the flowerpot 3 and can prevent drying for a long time.

[0003]

The above-mentioned conventional water supply apparatus has the following problems. In order to prevent the soil from spilling out from the hole 3a formed on the bottom side of the flower pot 3, a net may be provided on the bottom side of the flower pot 3 so as to cover the hole 3a. Obi 2
Could not be set in the flowerpot 3.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and is a water supply device for sucking water stored in a water receiving tray in a state where a flower pot is placed on the water receiving tray. An object of the present invention is to provide a water supply device that can be generally applied to existing flower pots.

[0005]

Means for Solving the Problems To achieve the above object, the invention according to claim 1 is a water supply device for sucking up water stored in a water pot with a flower pot placed on the water tray. A substantially string-shaped water supply zone having good water absorption is inserted and formed so as to extend from one end to the other end of the cylindrical body, and while extending upward from the inside of the water receiving tray on the outer wall side of the flowerpot. And a water supply pipe which is curved inward so as to straddle the outer wall at the upper open end of the flower pot and has a curved end inserted into the soil surface.

[0006] In the invention according to claim 1 configured as described above, a water supply pipe formed by inserting a substantially string-like water supply zone having good water absorption from one end to the other end of the cylindrical body. When applying to a flower pot placed on a water tray, the outside wall side of the flower pot extends upward from inside the water tray, and curves inward to straddle the outer wall at the upper open end of the flower pot And insert the curved end into the soil surface. Then, water is sucked up from the end of the water supply pipe on the side of the water tray, and supplied to the medium on the other end.

[0007] As described above, the water supply pipe only needs to be able to suck up water at the one end thereof by a water supply belt inserted therein and supply water at the other end inserted into the soil. It is optional, and specifically, an existing resin or the like formed in a sponge shape can be used.
Further, as this kind of resin, a resin that expands by containing water is known, and as an example of a suitable configuration in such a case, the invention according to claim 2 is based on the water supply device according to claim 1. The water supply zone is formed of a material that expands due to moisture, so that a gap is formed between the outer peripheral surface of the water supply zone and the inner peripheral surface of the cylindrical body when the water supply zone is not wet. It is composed. In the invention according to claim 2 configured as described above, the water supply zone expands by containing water, but when the water supply zone is not wet, a gap is formed between the outer peripheral surface and the inner peripheral surface of the cylindrical body. The expansion of the water supply zone is not impeded.

[0008] As an example of a more specific configuration in such a case, the invention according to claim 3 is the water supply device according to claim 2, wherein the water supply zone is formed in a substantially columnar shape, and The body is configured to be formed in a cylindrical shape. That is, since the water supply zone is formed in a substantially columnar shape that can be inserted into a substantially cylindrical tubular body, a gap is naturally formed between the outer peripheral surface of the water supply zone and the inner peripheral surface of the cylindrical body. . Further, if the gap is not collapsed even by expansion due to the water content of the water supply zone, it can be said that water is sucked up by capillary action, which is preferable.

By the way, since fertilizer is usually given to a plant, it is preferable that fertilizer can be given using such a water supply device. As an example, it is possible to dissolve a water-soluble fertilizer in water stored in a water receiving tray, and to suck up and feed the water containing the fertilizer. Further, as another example, the invention according to claim 4 is as follows.
In the water supply device according to any one of claims 1 to 3, the water supply zone is configured to contain a water-soluble fertilizer. In the invention according to claim 4 configured as described above, as described above, the water supply zone sucks water from the water receiving tray at one end thereof and supplies water at the other end thereof. The fertilizer contained in the water supply zone melts out and is supplied with the water supply. Of course, various methods can be applied here as a method for incorporating a fertilizer into the water supply zone, and there is no particular limitation. For example,
By immersing the water supply zone in an aqueous solution of fertilizer and then drying it, the water supply zone may be made to contain fertilizer, or a granular water-soluble fertilizer may be directly accommodated in the water supply zone.

As described above, the water supply pipe may be formed by inserting a cord-shaped water supply zone into a cylindrical body, but it is not always necessary to provide the water supply pipe in a completed state. Providing the user with the body and the water supply zone as separate bodies,
The water supply zone may be inserted into the cylinder by the user. Therefore, as an example of a suitable configuration in this case, the invention according to claim 5 is the water supply device according to any one of claims 1 to 4, wherein the water supply zone is replaceable with respect to the cylindrical body. To be inserted into the device. In other words, if the water supply pipe inside is dirty due to continuous use of the water supply pipe, or the water absorption capacity of the water supply pipe is reduced, it is sufficient to replace only the water supply pipe with a new one, and replace the entire water supply pipe. do not have to.

The role of the cylinder into which the water supply zone is inserted is as follows.
While inserting and protecting the water supply zone inside, the water supply zone extends inward from the inside of the water receiving tray so as to straddle the outer wall at the upper open end of the flower pot while extending the outer wall side of the flower pot upward. As long as it can be inserted into the soil, various shapes can be adopted. As an example thereof, the invention according to claim 6 is the water supply device according to any one of claims 1 to 5, wherein the tubular body is formed so that the inside can be seen through. In the invention according to claim 6 configured as described above, the inside of the cylindrical body can be seen through, and the state of the water supply zone inserted inside can be visually recognized. For example, as described above, it can be determined whether or not the water supply zone is dirty. In addition, by coloring the water supply zone itself, the visual appeal increases, the color coordination can be enjoyed according to the plant to be cultivated, etc., and the stain can be made inconspicuous by coloring in a specific color. .

As described above, the water supply pipe is curved inward so as to straddle the outer wall at the upper open end of the flowerpot, but the curved shape does not necessarily need to be fixed. For example, the pipe body of the water supply pipe may be configured to be freely curved, and may be used by appropriately bending the water supply zone as described above, as an example of a specific configuration thereof.
According to a seventh aspect of the present invention, in the water supply device according to any one of the first to sixth aspects, the cylindrical body has a configuration in which a curved portion is formed in a bellows shape. In the invention according to claim 7 configured as described above, since the curved portion of the cylindrical body is formed in a bellows shape, it can be easily curved, and the original cylindrical shape other than the curved portion is provided. Will be maintained.

The size of the flower pot to which such a water supply pipe is applied varies widely, and a water supply pipe having an appropriate length may be used according to the size. Therefore, in view of such circumstances, the invention according to claim 8 is the water supply device according to any one of claims 1 to 7, wherein the water supply pipe is appropriately cut to adjust the length. . That is, when the water supply pipe is too long for the flower pot to be applied, the length of the water supply pipe is appropriately cut to adjust the length of the water supply pipe to match the size of the flower pot.

By the way, the flowerpot is placed on the water tray, but this does not necessarily mean that the flowerpot is placed directly in the water tray. For example, the invention according to claim 9 is based on claim 1. The water supply device according to any one of claims to 8, further comprising a mounting table for mounting the flowerpot on the water tray in a stilt shape. In the invention according to claim 9 configured as described above, the mounting table is mounted on the water receiving tray, and the flowerpot is mounted thereon.
In other words, many flower pots have drainage holes formed on the bottom surface, so if they are placed directly in a water receiving tray in which water is stored, the soil is immersed in water through the drainage holes. May cause root rot. Therefore, it is preferable that the soil is immersed in water and that insects can be prevented from entering from the bottom side if the soil is placed on a mounting table to form a raised floor.

Needless to say, the mounting table may be any type as long as a flowerpot can be mounted thereon, and various types of shapes can be applied without any particular limitation. As an example, the invention according to claim 10 is the water supply device according to claim 9, wherein the mounting table is formed by combining a plurality of flat plates. That is, a plurality of flat plates are provided to the user, and the user assembles the mounting table using the plurality of flat plates. Needless to say, it is preferable to form the flat plates in the same shape without having to consider the types of parts.

As an example of a specific configuration in a case where the mounting table is assembled using a plurality of flat plates as described above, claim 11 is an example.
According to the invention according to claim 10, in the water supply device according to claim 10, the flat plate is formed in a substantially rectangular shape, and a pair of cuts are formed at side edges in directions opposite to each other slightly from the center from both ends, The mounting table has a configuration in which cutouts of the above-mentioned flat plates different from each other are inserted into each other to form a substantially regular upper surface polygon. Claim 1 configured as described above.
In the invention according to the first aspect, each flat plate is formed in a rectangular shape, and a pair of cuts are formed in side edges in directions opposite to each other slightly from the center from both ends, and different flat plates are used when assembling the mounting table. Insert the notches and assemble them so that the upper surface becomes a substantially regular polygon. For example,
When three flat plates are used, a mounting table having a substantially equilateral triangle on the upper surface is assembled. Needless to say, no adhesive or tool is required during assembly.

The water receiving tray is not particularly limited as long as it can store water while placing a flower pot thereon, and can be of various shapes. For example, the water tray may be constituted by one part, or the water tray may be constituted by a plurality of parts as a whole. Therefore, as an example of the latter, the invention according to claim 12 is the water supply device according to any one of claims 1 to 11, wherein the water receiving tray includes a mounting plate for mounting the flowerpot, The water supply pipe is provided with a substantially deep dish-shaped water reservoir that can store water while being inserted from the upper opening at the lower end portion of the water supply pipe.

That is, the water receiving tray is composed of a placing tray and a substantially deep dish-shaped reservoir, on which a flowerpot is placed, and the lower end of the water supply pipe is opened upward. Collect water while inserting from. Then, similarly, the water supply zone sucks up the water in the water storage dish and supplies the water. Of course, the water storage tray can be widely applied as long as it has an opening on the upper side into which a water supply pipe can be inserted and can store water while being formed in a substantially deep dish shape as a whole. It is also possible.

Further, according to a thirteenth aspect of the present invention, there is provided a resin tubular body whose inside can be seen through, wherein a bellows portion is formed in the middle so that the distal end can be freely bent. Is formed in such a position that it can penetrate into the surface soil inside the flower pot by crossing the upper end edge from the side with respect to the flower pot, and the rear end side is immersed in a water receiving tray for the flower pot. Formed at a certain length, and both ends protrude from the cylindrical body while inserting a porous string having high water absorption into the cylindrical body, and expand at the time of water absorption to expand the peripheral wall surface of the cylindrical body. To improve the wicking performance, and when the cylindrical body is pierced from the water receiving tray over the upper edge of the flower pot toward the soil in the flower pot, the water in the water receiving tray is in the string state. And suck it up in the cylinder There is a configuration that allows the water supply to the soil of the serial in a flowerpot.

In the invention according to the thirteenth aspect, the cylindrical body is made of a resin whose inside can be seen through, and a bellows portion is formed in the middle thereof so that the tip side can be freely bent. The bellows portion is formed at such a position that the cylindrical body can be pierced into the surface soil in the flower pot by climbing over the upper end edge from the side with respect to the flower pot, and the rear end side is provided with respect to the flower pot. It is formed in such a length that it is immersed in the water receiving tray. A porous string having high water absorbency is inserted into the cylindrical body, and both ends are configured to protrude from the cylindrical body.
When the cylindrical body having such a configuration is pierced from the water receiving tray toward the soil in the flower pot over the upper end edge of the flower pot, the string-shaped body inserted into the cylindrical body is in the water receiving tray. Water is sucked up in the cylinder, expanded at the time of the water absorption, comes into contact with the peripheral wall surface of the cylinder, and supplies water to the soil in the flowerpot while improving the suction performance.

[0021]

As described above, according to the present invention, a water supply pipe is formed by inserting a substantially string-like water supply zone having good water absorption from one end of the cylindrical body to the other end. While extending the outer wall side of the flower pot upward from the inside of the water receiving tray, it is bent inward so as to straddle the outer wall at the upper open end of the flower pot, and the end in the bending direction is inserted into the soil surface. Because we took up water stored in saucer and supplied water,
It is possible to provide a water supply device that can be applied to existing flower pots in a general-purpose manner while preventing drying of the soil with an extremely simple configuration. According to the second aspect of the invention, when a water supply zone that expands due to water content is used, a gap is formed between the outer peripheral surface of the water supply zone and the inner peripheral surface of the cylinder in anticipation of the expansion. , The expansion of the water supply zone is not hindered, there is no inconvenience such as a decrease in water absorption capacity,
According to the third aspect of the invention, a specific configuration in such a case can be provided.

Further, according to the invention of claim 4,
Since the water supply zone contains water-soluble fertilizer and the fertilizer is provided along with the water supply, there is no need for the user to individually apply the fertilizer. Furthermore, according to the invention according to claim 5, when the water supply zone becomes dirty or the water absorption capacity decreases,
Only the water supply zone needs to be replaced, which is efficient. Furthermore, according to the invention according to claim 6, since the inside of the cylindrical body constituting the water supply zone can be seen through, the inside water supply zone can be visually recognized, and it can be said that it is easy to find dirt in the water supply zone, and it is colored. The appearance can be improved by using the provided water zone.

Further, according to the invention according to claim 7,
Since the curved portion of the cylindrical body constituting the water supply zone is formed in a bellows shape, it can be easily curved at the curved portion,
The normal cylindrical shape can be maintained except for the curved portion. Furthermore, according to the invention of claim 8, since the length of the water supply pipe can be adjusted by appropriately cutting the water supply pipe, it can be adapted to flowerpots of various sizes. Further, according to the ninth aspect of the present invention, since the flowerpot is placed on the mounting table in the water receiving tray, the soil is immersed in the water through the drainage hole formed on the bottom side of the flowerpot. Root rot is unlikely to occur, and insects can be prevented from entering from the bottom side.

Further, according to the tenth aspect of the present invention, since the mounting table is formed by combining a plurality of flat plates, it is possible to prevent bulkiness in a state before assembling such as when providing to a user. According to the eleventh aspect of the present invention, a specific configuration can be provided. Further, according to the twelfth aspect of the present invention, water is stored in a substantially deep dish-shaped water storage tray that constitutes a water receiving tray, and a water supply pipe is inserted to supply water, so that water is supplied over a long period of time. No need. Further, according to the invention of claim 13, a water supply device having a more specific configuration can be provided.

[0025]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a water supply device according to an embodiment of the present invention. In this figure, a water supply device 10 is provided with a water supply pipe 4 formed by a substantially cylindrical cylinder 20 and a water supply zone 30 inserted into the cylinder 20.
0 and a mounting table 50 for mounting the flowerpot.

The cylindrical body 20 is made of a polypropylene material and is formed in a semi-transparent cylindrical shape. It is bendable. As shown in FIG. 2, the bending portion 21 can be expanded and contracted as a whole, and in actual bending, the bending portion 21 is bent in a contracted state. Then, as shown in FIG. 3, the side opposite to the bending direction of the bending portion 21 extends so that the bending shape is maintained. That is, this type of shape is the same as that conventionally applied to a straw as a beverage tool, and such a straw may be applied as it is as the cylindrical body 20 of the present embodiment.

In the present embodiment, the above-described bending portion 21 is formed at a predetermined position of the cylindrical body 20 so as to be able to bend. However, it is needless to say that the present invention is not limited to this configuration. For example, the cylindrical body 120 shown in FIG. 4 is entirely formed of a stretchable plastic resin and can be bent at a desired position, and such a cylindrical body 120 can be applied.

The water supply zone 30 is formed by cutting a sheet-like water-absorbing material into narrow strips as shown in FIG.
As a specific water-absorbing material, any material having good water absorption may be used, and various materials can be applied. Experiments were conducted using various water-absorbing materials, and it was found that when a sponge (porous) made of a polyvinyl alcohol material was used, it was possible to siphon up to a height of 20 cm or more. We will use alcohol materials.

As shown in the plan view of FIG. 6, the water supply zone 30 can be inserted into the cylindrical body 20. Specifically, the inner diameter of the cylindrical body 20 is 6 mm, and the water supply zone 30 has a cross section of 4 mm × 2 mm. It is made to become. Further, as can be seen from the figure, the water supply zone 30 is slightly longer than the cylindrical body 20, and is inserted into the cylindrical body 20 such that both ends thereof are exposed from both ends of the cylindrical body 20. Of course, since the water supply zone 30 is formed in a strip shape from a polyvinyl alcohol material, it can be bent, and even if the bending portion 21 is bent at an acute angle in a state of being inserted into the cylindrical body 20 as shown in FIG. 7, its curved shape is maintained. Then, since the curved shape is maintained in this manner, after being once curved, the internal water supply zone 30 does not fall out of the cylindrical body 20.

FIG. 8 is a sectional view showing a water supply pipe 40 formed by inserting the water supply zone 30 into the cylindrical body 20. As described above, since the water supply zone 30 is narrower than the inner diameter of the cylindrical body 20, a slight gap is formed between the corner and the cylindrical body 20. Of course, this is a state in which the water supply zone 30 does not contain water. Since the water supply zone 30 is formed of a polyvinyl alcohol material, the water supply zone 30 has a volume ratio of about 2 due to water content.
It expands by about 0%. Then, when the water supply zone 30 contains water, the corners of the water supply zone 30 abut against the inner peripheral surface of the cylindrical body 20 as shown in FIG.

Originally, it is sufficient that the water supply zone 30 can be inserted into the cylindrical body 20. For example, the water supply zone 30 may be formed in a substantially columnar shape that is in close contact with the inner peripheral surface of the cylindrical body 20 when not containing water. However, since the water supply zone 30 is made of a porous polyvinyl alcohol material, if the water supply zone 30 has a shape that prevents expansion by the cylindrical body 20, the water supply zone 30 may be crushed as a whole and exhibit its original water absorbing ability. It may not be possible. Therefore, when the water supply zone 30 formed in a strip shape slightly narrower than the cylindrical body 20 is used as in the present embodiment, the expansion is not hindered, and the reduction in the water absorption capacity as described above occurs. I can't say that.

The mounting table 50 can be assembled using an assembly piece 51 as shown in the plan view of FIG. In the figure, an assembly piece 51 is formed of a substantially rectangular flat resin, and its width direction is gradually narrowed from both ends toward the center. Further, a pair of cuts 51 extending from the opposite side edges to the middle in the width direction at a position slightly from the center from both ends of the assembly piece 51, respectively.
a and 51a are formed. Of course, this cut 51
a, 51a are wider than the thickness of the assembly piece 51, and in this embodiment, the mounting table 50 is assembled using three assembly pieces 51, 51, 51 as shown in FIG.

In the figure, first, two different assembly pieces 5
After inserting the cuts 51a, 51a into the cut pieces 51a, 51a so that the side edges of the cut pieces 51a, 51a face each other, another cut 51a,
Cuts 51a, 51 of another assembly piece 51 with respect to 51a
When a is similarly inserted into each other, a mounting table 50 having a substantially triangular upper surface is formed. Although not described above, each assembly 51
Is flexible as a whole, and can be performed while appropriately bending each assembly piece 51 when performing an actual assembling operation, so that the assembling operation can be performed without difficulty. In addition, since each of the assembly pieces has the same shape, only one kind of component is required, which not only can reduce the manufacturing cost, but also allows the user to assemble without having to be conscious of the type of component. is there.

As described above, in the present embodiment, the mounting table 50 having a substantially triangular upper surface is assembled using the three assembly pieces 51, 51, 51. Of course, such a mounting table will be described later. It is sufficient that the flower pot can be stably placed on the upper surface side, and can be changed as appropriate. For example, when a flower pot to be mounted is large and cannot be stably mounted depending on the mounting table 50, the upper surface is formed in a substantially pentagonal shape using five assembly pieces 51 as shown in FIG. By assembling the mounting table 150 as described above, it is possible to cope with a larger flowerpot.

Next, the operation of this embodiment having the above configuration will be described. The water supply zone 30 is inserted into the cylindrical body 20 in advance, and FIG.
As shown in FIG. 11, a plurality of water supply pipes 40, each of which is bent at an acute angle by the bending portion 21, are prepared, and a substantially triangular upper surface is mounted by using three assembly pieces 51, 51, 51 as shown in FIG. The table 50 is assembled. Then, as shown in FIG. 13, the mounting table 50 is placed on the bottom of a substantially thin dish-shaped water receiving tray 60 so as to lie down, and water is stored in the water receiving tray 60 so as not to be higher than the height of the mounting table 50. After the mounting table 50
The flowerpot 70 is placed on the upper surface side of the.

As described above, since each of the assembly pieces 51 constituting the mounting table 50 gradually narrows toward the center, as can be seen from FIG. The lower surface side is formed slightly concave. On the other hand, the flowerpot 70 is formed so as to become narrower from the upper side to the bottom side. When the flowerpot 70 is mounted on the mounting table 50, it is shown in a top view of FIG. 14 and a side view of FIG. As shown in FIG.
It is placed so as to rest on the concave portion of 0. Then, flowerpot 7
Even if some force is applied in the horizontal direction with respect to 0, it will not easily slip off from the mounting table 50, and
0 is stably mounted on the mounting table 50. FIG.
16, a hole 71 is formed in the bottom surface of the flowerpot 70, and as shown in FIG. 16, a net 7 is formed on the bottom surface of the flowerpot 70 so as to close the hole 71 before filling the soil in the flowerpot 70.
2 is placed, and the soil is piled on it. Thereby, the inside of the flowerpot 70 can be drained while preventing soil from spilling out from the hole 71.

The significance of placing the flowerpot 70 on the upper surface of the mounting table 50 in this way is to prevent the water stored in the water receiving tray 60 from entering through the hole 71 formed on the bottom side of the flowerpot 70. To do that. That is, if the soil in the flowerpot 70 becomes wet more than necessary, it may cause root rot or the like, so that the hole 71 does not come into contact with the water stored in the water receiving tray 60. Furthermore, placing the flowerpot 70 on the mounting table 50 makes it difficult for insects to enter, and it can be said that this is also preferable in this sense.

The flowerpot 7 is placed on the mounting table 50 as described above.
17, the curved portion 21 of the water supply pipe 40 prepared in advance is placed on the upper side, and the lower portion thereof is made to follow the outer wall of the flowerpot 70, as shown in FIG.
The end in the bending direction is inserted into the soil 73 so as to straddle the wall surface at the upper open end of 0. More specifically, as shown in FIGS. 18 and 19, the end portion in the bending direction can be inserted into the soil 73 in the flowerpot 70 by pressing it with a finger. Thereafter, the remaining water supply pipe 40 prepared in advance is similarly arranged at an appropriate location. Although not described above, as can be seen from FIG. 17, the bottom side of the flowerpot 70 is of a raised floor type, so that even if the water is It is almost impossible for water to infiltrate.

Referring to FIG. 17, it can be seen that the lower end of each water supply pipe 40 arranged as described above is immersed in the water stored in the water receiving tray 60. Then, the water in the water receiving tray 60 is sucked up by the water supply zone 30 exposed at the lower end, and the water is supplied at another end inserted into the soil 73. Of course, the appropriate length of the water supply pipe 40 varies depending on the size of the flower pot to be applied. Therefore, when the length of the water supply pipe 40 is too long, the lower end portion of the water supply pipe 40 may be appropriately cut and used as shown in FIG. Further, referring to the cross-sectional view of FIG. 9, the water supply zone 30 expands when containing water, and a capillary gap is formed between the outer wall thereof and the inner peripheral surface of the cylindrical body 20. It can be said that it is preferable to be sucked up.

As a result of an experiment using the above configuration, it was found that water could be supplied for several days. Therefore, even when the user is away from home for several days, if an appropriate amount of water is stored in the water receiving tray 60 in advance, an appropriate amount of water is supplied and the soil 73 is prevented from drying. be able to. Of course, the appropriate amount of water supply depends on the amount of the soil 73 in the flowerpot 70, the type of plant to be cultivated, and the like, so that the appropriate amount of water supply is adjusted according to such circumstances.
What is necessary is just to adjust suitably the number of the water supply pipes 40 actually set. In the water supply method in which water is sprayed from above on the soil in the flowerpot, the surface of the soil may be dried and hardened. However, in the present embodiment, water is supplied little by little continuously, and water is supplied in a state where one end of the water supply zone 30 is inserted into the soil 73.
The surface does not become hard.

Further, since the inside of the cylindrical body 20 constituting the water supply pipe 40 is formed so as to be able to be seen through, when the water supply pipe 30 is continuously used and the internal water supply zone 30 becomes conspicuous, the water supply pipe 40 becomes invisible. May be removed from the flowerpot, the water supply zone 30 may be replaced with a new one after the tubular body 20 is once straightened, and the waterbag 30 may be bent again and set in the flowerpot 70. Of course, even when it is considered that the water absorption capacity of the water supply zone 30 has decreased, the water supply zone 30 may be replaced with a new one in the same manner. Furthermore, since the inside of the cylindrical body 20 can be seen through, the appearance can be improved by performing color coordination or the like using the water supply zone 30 colored in various colors.

By the way, fertilizer is usually given to a plant. Therefore, fertilizer may be given along with water supply by the water supply pipe 40. For example, water tray 60
If an appropriate amount of water-soluble fertilizer is dissolved in the water stored in the plant, the fertilizer will be given to the plant with the water supply. Also,
As shown in the enlarged view of FIG. 21, if the granular water-soluble fertilizer 31 is accommodated in the length direction of the water supply zone 30, the water-soluble fertilizer 31 gradually dissolves with the water supply and is given to the plant. And the same effect can be obtained.

Further, in the present embodiment, the water tray 60 having a substantially thin plate shape is used, but, of course, the water tray actually used is not limited to such a shape. For example, in the one shown in FIG.
Numeral 60 denotes a substantially thin dish-shaped placing dish 161 and a water storage dish 162 using a plastic bottle or the like in which water is stored. The flowerpot 70 is placed on the placing dish 161 and the water supply pipe 4 is provided.
The lower end of 0 is inserted into the water dish 162. Then
