Description

Flowerpot with adjustable drainage flow and water level and drainage structures for the same}

The present invention relates to a potted plant capable of controlling the drainage flow rate and water level and a drainage structure therefor, and the drainage flow rate configured so that the drainage flow rate (drainage delay) and water level can be easily adjusted during drainage through the bottom and/or side side And it relates to a water level controllable flowerpot and a drainage structure therefor.

Pots need a constant supply of water in the right amount so that plants can survive and grow.

As an example, a method of directly periodically watering a pot is used, and as another example, a pot with a water absorption hole formed at the bottom is stored in the drip tray and water is supplied to the drip tray so that the plants in the pot absorb water. The way to do it is also used.

However, in the case of a method using a drip tray, it is necessary to properly maintain the water level stored in the drip tray. If the water level is too low, it may be difficult for plants to absorb water, and if the water level is too high, the roots of the plant may rot or the water that has been standing for a long time will rot, causing problems such as odor. Also, there may be a difference in the appropriate water level depending on the type of plant.

On the other hand, recently, in the case of a flowerpot installed for wall decoration (wall greening), it has a structure in which a small flowerpot casing is accommodated in a drip tray casing, and a plurality of flowerpots having such a structure are stacked and coupled in the vertical direction.

However, the pots of the top and bottom stacked combined structure are difficult to manage because the water level in multiple pots that are installed together must be maintained and managed. There were difficulties.

In addition, the potted plant of the upper and lower stacked combination structure generally takes a configuration in which water is supplied to the uppermost potted plant when water is supplied, and water discharged through the bottom drain pipe is supplied to the lower potter to be sequentially supplied with water. , Because there is a difference between the time when water is supplied to the upper pot and the time when water is supplied to the lower pot due to the water flow structure in the upper->down direction, it is possible to quickly supply water to the lower pot when water is supplied through the upper pot. There was a limitation that it was difficult.

1 is a perspective view of a flowerpot according to an embodiment of the present invention, FIG. 2 is an excerpted perspective view illustrating a coupling state of a drain pipe and a drainage control tube of a flowerpot according to an embodiment of the present invention, and FIG. 3 is another embodiment of the present invention It is an excerpted perspective view illustrating the coupling state of the drain pipe and the drain control pipe of the flowerpot according to

In the flowerpot 10 of this embodiment, the drainage flow rate (drainage delay) and water level can be easily adjusted when draining another flowerpot located on the lower floor or to the outside through the drain pipe 120 formed to extend toward the upper side of the bottom part 110. is configured to

For example, it is necessary to control the water level of the water stored in the pot when watering the pot and draining it. This is to set the water level so that the roots can be immersed in water to a minimum if necessary, according to the type and characteristics of each plant.

As another example, it may be necessary to adjust the hourly drainage flow rate for water in the pot separately from controlling the water level in the pot. For example, with a large inflow rate such as during a rainy season, the plants in the pot are immersed in water for a short time, and then after the plants are wetted with sufficient water, the drainage flow rate can be adjusted to be small so that they can be drained gradually. After that, in the completely drained state, oxygen is smoothly supplied to the roots of the plants in the pot, so that the roots do not rot and they can exercise vigorously and then supply water again at regular intervals.

From another point of view, adjusting the drainage flow rate of water introduced into the pot may be viewed as controlling the drainage delay condition. In other words, setting the drainage flow rate to be small when water is flowing in or flowing into the pot at a large flow rate is the same as setting the drainage delay to be large. Setting the drainage flow rate to be large sets the drainage delay to be small it's like doing

In consideration of this, the flowerpot 10 of the present embodiment is configured to provide drainage flow rate (drainage delay) and water level control functions during drainage.

To this end, the flowerpot 10 of this embodiment includes a drain pipe 120 and a drain control pipe 130 .

The drain pipe 120 includes a linear section extending along the vertical direction (A1-A2) toward the upper side of the bottom part 110, and first draining through holes 120b and 120c are formed in the upper part and the lower part, respectively. A first drain pipe hole 120a having a hollow tube structure and extending to have a vertical height difference is formed on one side of the side surface of the linear section.

The first drain pipe hole 120a may have an open top as illustrated in FIG. 4 , or may have both ends closed as illustrated in FIG. 6 .

The drainage control tube 130 is formed to extend along the vertical direction (A1-A2), has a hollow tube structure in which second drainage through-holes 130b and 130c are formed at the upper end and lower end, respectively, and the upper and lower sides on one side A second drain pipe hole 130a extending to have a height difference is formed. The drain control pipe 130 is formed to be closely inserted into the hollow pipe of the linear section of the drain pipe 120 . It is preferable that the drain control pipe 130 be formed of a softer material than the drain pipe 120 for smooth insertion.

One or more of the first drain pipe hole 120a and the second drain pipe hole 130a may be formed, respectively, and the number is not limited.

Water in the flowerpot flows into the drain pipe 120 through the area FA where the first drain pipe hole 120a and the second drain pipe hole 130a overlap, and the first drain formed at the lower end of the drain pipe 120 Water introduced into the drain pipe 120 through the receiving through-hole 120c is discharged to the lower side of the pot.

In a state where the water level in the pot is higher than the first through-hole for drainage 120b and the second through-hole 130b for drainage on the upper side, the first through-hole for drainage 120b and the second through-hole for drainage on the upper side ( 130b), the water inside the pot is also discharged to the lower side of the pot, and in this case, the water is discharged through only the area FA where the first drain pipe hole 120a and the second drain pipe hole 130a overlap. With a large flow rate, the water inside the pot can be discharged to the lower side of the pot.

Through the above configuration, when the water level in the pot is high, water can be drained more quickly through the first through-hole for drainage 120b and the second through-hole for drainage 130b on the upper end side.

In addition, through the above configuration, as shown in FIG. 2 , in the state in which the drain control pipe 130 is closely inserted into the inside of the drain pipe 120 , the height in the vertical direction (A1-A2) and the rotation direction (P1-P2) are As at least one is adjusted, the size and height (height of PP1) of the area FA where the first drain pipe hole 120a and the second drain pipe hole 130a overlap are changed, so that the first drain pipe path It is possible to control the drain rate of water drained through the area FA where the hole 120a and the second drain pipe hole 130a overlap and the level of water remaining in the pot body part 100 . Reference numeral PP1 in FIG. 2 denotes the lowest point of the area FA where the first drain pipe hole 120a and the second drain pipe hole 130a overlap.

The area FA where the first drain hole 120a and the second drain hole 130a overlap defines the size of the drain passage through which water in the flowerpot 10 is drained.

For example, when the second drain pipe hole 130a is rotated in the P2 direction to the state of FIG. 2 (b) based on the state of FIG. 2 (a), the first drain hole 120a and the second Since the height (the height of PP1) of the area FA where the drain pipe hole 130a overlaps becomes lower, the water level of the water remaining in the pot after drainage is lowered.

Conversely, when the second drain pipe hole 130a is rotated in the P1 direction to the state of FIG. 2 (a) based on the state of FIG. 2 (b), the first drain hole 120a and the Since the height (the height of PP1) of the area FA where the drain pipe hole 130a overlaps becomes higher, the level of water remaining in the flowerpot after drainage becomes higher.

As another example, while rotating the second drain pipe hole 130a in the P2 direction to the state of FIG. 2 (c) based on the state of FIG. (A1-A2) When the height is lowered, the size of the area FA where the first drain pipe hole 120a and the second drain pipe hole 130a overlap becomes larger, so that the drain rate of water discharged to the outside per hour this will increase At the same time, since the height (the height of PP1) of the area FA where the first drain hole 120a and the second drain hole 130a overlap becomes lower, the level of water remaining in the pot after draining is higher. will be lowered

Conversely, while rotating the second drain pipe hole 130a in the P1 direction to the state of FIG. 2 (a) based on the state of (c) of FIG. A1-A2) If the height is increased, the size of the area FA where the first drain pipe hole 120a and the second drain pipe hole 130a overlap becomes smaller. will decrease At the same time, since the height (the height of PP1) of the area FA where the first drain pipe hole 120a and the second drain pipe hole 130a overlap becomes higher, the water level remaining in the pot after drainage becomes higher. do.

The first drain pipe hole 120a and the second drain pipe hole 130a may be formed in the shape of a straight line, an oblique line, a triangle, an inverted triangle, etc. as shown in FIG. 3 , but as a preferred example, the first drain pipe It is preferable that the low hole 120a is formed in the shape of one diagonal line extending to have a vertical height difference, and the second drain pipe hole 130a is formed in the shape of one straight line extending along the vertical direction. The diagonal line is formed to extend to have a predetermined width.

For example, in the case of an upper pot among the pots 10 stacked up and down in several layers, in the initial state when the user supplies water from the upper part of the pot, the water level in the pot rises rapidly, so the water level in the pot is quickly transferred to the pot in the lower layer. It is preferable to discharge After the supply of water from the upper part of the pot is finished, in a state where water needs to be maintained in the pot, it is preferable to reduce the rate at which water is discharged to the lower part as the water level in the pot is lowered. In consideration of this point, the first drain pipe hole 120a is formed in the form of one diagonal line extending to have a vertical height difference, and the second drain pipe hole 130a is a single straight line extending along the vertical direction. It is better to be in the form. As a preferred example, the drain structure formed in a single straight line in which the second drain pipe hole 130a extends in the vertical direction and has a length smaller than the vertical height difference of the first drain pipe hole 120a is of this type To make drainage control operation easier. For example, the states (a) and (c) of Fig. 2 are suitable for such a water drainage control operation. In addition, if necessary, the drainage control operation may be performed in various states as in the state of FIG. 2B .

As a modification, as shown in (d) of FIG. 3 , the second drain pipe hole 130-1 extends to have a vertical height difference, and is a diagonal line having a different angle from that of the first drain pipe hole 120a. It may be formed in a shape.

Meanwhile, in the above description, although the flowerpot 10 in which several layers are stacked up and down has been described as an example, even in the case of a flowerpot arranged in one layer, when water is drained downward, the drainage flow rate (drainage delay) and water level control of this embodiment Of course, the configuration for the can be applied.

On the other hand, a fine sealing element (not shown) may be provided on the outer side or the hollow inner side of the drain pipe 120 and/or the drain control pipe 130 to further strengthen the mutually inserted adhesion state. For example, the fine sealing element may be configured in such a way that a small-diameter O-ring-shaped sealing element is inserted into the space between the drain pipe 120 and/or the drain control pipe 130 , and the drain pipe 120 and/or A sealing pattern providing a function similar to an O-ring may be integrally formed on the outer side or the hollow inner side of the drain control pipe 130 .

7 is a perspective view of a flowerpot according to another embodiment of the present invention.

The pot 10 of this embodiment enables rapid water supply to the lower pot when water is supplied to the lower pot through the upper pot in the pot of the upper and lower stacked combination structure, and when the drain pipe 120 is clogged due to foreign substances, As a configuration for preventing water from flowing back, it further includes a large flow rate drain pipe 1120 .

The high flow rate drain pipe 1120 has a hollow tube structure extending upward and downward from the bottom part 110 and having third through-holes 1120b and 1120c formed at the upper end and lower end, respectively.

In addition, the large flow rate drain pipe 1120 is formed to have a larger inner diameter and a larger height than the drain pipe 120 .

For example, in the case of an upper pot among the pots 10 stacked up and down in several layers, in the initial state of supplying water from the outside, the water level in the pot rises rapidly, so the water is discharged to the pot of the lower layer at a fast flow rate. it is preferable After the supply of water from the outside is terminated, in a state in which water must be maintained in the pot, it is preferable to reduce the rate at which water is discharged to the lower part as the water level in the pot is lowered.

In the case of taking the configuration of FIG. 7, when the water level in the pot rises rapidly, the water drain rate is increased through the large flow rate drain pipe 1120 to induce fast drainage, and the water level is lowered to keep the water in the pot. Through the drain pipe 120 and the drain control pipe 130, it is possible to control the drainage step-by-step so that drainage is performed according to the reduced flow rate and water level adjusted in advance.

In addition, in the case of taking the configuration of FIG. 7 , when water is supplied to the lower pot through the upper pot in the pot of the upper and lower stacked combined structure, it is possible to quickly supply water to the lower pot.

In addition, in the case of taking the configuration of Figure 7, the water in the pot is drained through the large flow rate drain pipe 1120 when the water level in the pot rises because the drain pipe 120 is blocked by foreign substances. can

Preferably, the third through-hole for drainage 1120b on the upper end side, which is the water inlet side of the large-flow drainage pipe 1120 , may include a filter element for filtering foreign substances contained in water. Such a filter element may be configured similarly to the shape of the upper plate 302 of FIG. 18 .

18 is a perspective view of a flowerpot according to another embodiment of the present invention.

The flowerpot of this embodiment is configured to further include a filter member 300 .

The filter member 300 has filter holes 302a and 304b formed therein and is formed to extend in a hollow shape, and the water drained by combining the upper and lower sides of the drain pipe 120 and the drain control pipe 130 to cover them. It is configured to filter foreign substances contained in the.

The filter member 300 illustrated in FIG. 18 is configured in a cylindrical shape, and is formed to extend hollowly to the lower side of the upper plate part 302 in which the first filter hole 302a is formed and the upper plate part 302, and has one or more products on the side surface. 2 It includes a cylindrical portion 304 having a filter hole 304a formed therein, and is configured to be coupled to the upper part and the side surface of the drain pipe 120 and/or the drain control pipe 130 to cover the upper part.

In particular, the size of the area FA where the first drain pipe hole 120a and the second drain pipe hole 130a overlap can be finely adjusted in size. It may not be possible to control the water level or the displacement of the bar. The filter member 300 is installed to prevent this problem.

Preferably, the filter member 300 is installed so as not to be in close contact with the outer surface of the drain pipe 120 and/or the drain control pipe 130 so that the first drain pipe hole 120a and the second drain pipe hole 130a overlap. It is configured not to affect the size adjustment of the area FA.

The filter member 300 is not limited to the shape illustrated in FIG. 18 , and various modifications such as a conical shape and a polygonal column shape are possible.

19 is an exploded perspective view illustrating a state in which a plurality of flowerpots are connected in a transverse direction according to another embodiment of the present invention, and FIGS. 20 and 21 are a plurality of flowerpots in a transverse direction according to another embodiment of the present invention A schematic diagram of the installation state of the drain pipe and the drain control pipe for connection, FIGS. 22 and 23 are schematic views of the installation state of the drain pipe and the drain control pipe for draining to the lower side of the flowerpot according to another embodiment of the present invention.

As described above, the drain pipe 120 may be integrally formed extending from the upper portion of the bottom portion 110 of the flowerpot body portion 100 ( FIGS. 1 and 11 ), or may be installed in a prefabricated manner ( FIGS. 19 to 19 ). Fig. 25). In addition, the lower end of the drain pipe 120 may be connected to the bottom portion 110 ( FIGS. 1 , 11 , 22 , and 23 ), and may be connected and installed to the sidewall portions 104 and 106 ( FIGS. 19 to FIG. 19 ). 21).

In particular, in the case of the embodiment of Figs. 19 to 23, a case in which the drain pipe 120 is prefabricated using the hollow silicone rubber hoses 20 and 22 is exemplified.

For example, in the embodiment of FIGS. 19 to 21 , a through hole 106a is formed on the lower side of the side wall portion 106 of the flowerpot body 100 , and the inner diameter d11 of the through hole 106a . A hollow silicone rubber hose 20 having a larger outer diameter d22 is inserted into the inner diameter surface of the through hole 106a to form a closely coupled state by elastic restoration, and the drain pipe formed in an “L” shape The lower end of the 2120 is inserted into the hollow inner surface side 20-1 of the silicone rubber hose 20 and installed.

Through the above configuration, the flowerpot of this embodiment has a first through hole 104a of one flowerpot 10 in a state where another flowerpot 10 is located adjacent to the left or right side of one flowerpot 10 . Water stored in one flowerpot 10 through a water supply pipe 20 interconnecting the second through-hole 106a of another flowerpot 10 with the other flowerpot 10 in the transverse direction It is designed to be supplied with

In addition, in this lateral water supply process, the size and height (PP1) of the area FA where the first drain pipe hole 2120a of the drain pipe 2120 and the second drain pipe hole 2130a of the drain control pipe 2130 overlap. height) to control the drainage flow rate of water drained in the lateral direction and the level of water remaining in the flowerpot 10 .

In this embodiment, one flowerpot 10 is not necessarily connected to only one other flowerpot 10, and by applying the water supply pipe connection structure of this embodiment to several sides, respectively, two or more located in front, rear, top, bottom, or left and right It can be connected to the flowerpot 10 at the same time.

The water supply pipe 20 is a hollow silicone rubber hose having an outer diameter d22 greater than the inner diameter d11 of the through-holes 104a and 106a, and an external force (eg, a force pressing with the operator's hand or instrument) The outer diameter d22 can be inserted into the through-holes 104a and 106a in an elastically reduced state by the and is configured to be closely coupled to the inner diameter surface of the through-holes 104a and 106a.

In general, since a large amount of water is not contained in the flowerpot 10, the water pressure is not high, so only the excellent elastic restoring force of the silicone rubber hose is sufficient for close bonding to the through-holes 104a and 106a of the flowerpot 10, and Water leakage can be prevented. In particular, when a silicone rubber hose with a thick tube thickness (the difference between the outer diameter and the inner diameter) is used, better restoring force and adhesion can be obtained. In addition, since the outer surface of the water supply pipe 20 strongly adheres to the through holes 104a and 106a by the elastic restoring force of the silicone rubber, water leakage is effectively prevented, and the water supply pipe 20 penetrates by the external force F1 or F2. Disengagement from the balls 104a and 106a is prevented.

For example, when the inner diameter d11 of the through-holes 104a and 106a is 9.5 mm, the outer diameter d22 of the water supply pipe 20 may be 10 mm, and the inner diameter d21 may be 6 mm, and the drain pipe 2120 ) is larger than the inner diameter d21 of the water supply pipe 20 in the case of FIG. 20, and is larger than the inner diameter d21 of the water supply pipe 20 in the case of FIG. d11).

As the silicone rubber hose of this embodiment, for example, a well-known silicone rubber hose commercially available for medical equipment or food machines may be used.

In terms of compression set, compression set of general organic rubber significantly increases with temperature change, whereas silicone rubber maintains elasticity and restoring force in a wide temperature range from -100 to 250 ° C. Even when this is required, excellent performance can be exhibited.

In terms of compression resistance, silicone rubber has a restoring property that returns to its original shape when pressed at a temperature of -85 to 260°C.

In terms of weather resistance, unlike other organic rubbers, silicone rubber has excellent weather resistance because there is no double bond that reacts with oxygen, ozone, and ultraviolet rays in the atmosphere in the molecular structure to cause cracks, so there is little change in physical properties even when left outdoors for a long time .

The present inventors, paying attention to the excellent elasticity and restoration characteristics, weather resistance, etc. of the silicone rubber, when using a silicone rubber hose as the water supply pipe 20, insert it into the through-holes 104a and 106a without using a separate packing member. It was also confirmed that the bonding state in which water does not leak can be maintained without being affected by external climate (eg, temperature change, oxidation, ozone, ultraviolet rays, etc.). The characteristics of these silicone rubber hoses are characteristics that cannot be obtained from other organic rubbers.

Preferably, the pot body part 100 is formed of a material harder than the silicone rubber hose (eg, hard synthetic resin). Through this, when the water supply pipe 20 inserted into the through-holes 104a and 106a in a state in which the outer diameter d22 is elastically reduced by an external force is elastically restored by removing the external force, the water supply pipe 20 Since the outer surface of and the through-holes 104a and 106a of the pot body part 100 form a strong contact state, water leakage is prevented, and the water supply pipe 20 is separated from the through-holes 104a and 106a by an external force. can be effectively prevented. In addition, it is preferable that the water supply pipe 20 is also formed of a material (eg, hard synthetic resin) that is harder than the silicone rubber hose.

The through-holes 104a and 106a of the side to which the water supply pipe 20 is not coupled may be blocked with a stopper 190 made of an elastic material.

Preferably, a guide protrusion piece 150 for limiting the lateral movement of the drain pipe 2120 is formed inside the side wall part 106 of the pot body part 100 .

For example, the guide protruding piece 150 may be formed in the form of two protruding pieces protruding in parallel from the inner side of the side wall portion 106 , but is not limited thereto. The upper end (linear section) of the drain pipe 2120 formed in an “L” shape is positioned in the space between the two parallel protruding pieces to prevent lateral movement such as inclination.

The lower end of the drain pipe 2120 may only be inserted and installed on the inner side of the hollow part of the silicone rubber hose 20 without passing through the through hole 106a as illustrated in FIG. It may be installed to pass through the through hole (106a) in a state inserted and installed on the inner side of the hollow part of the hose (20). In the case of FIG. 20, the lower end of the drain pipe 2120 only needs to be inserted into the inner side of the hollow part of the silicone rubber hose 20, so there is an advantage of convenient installation work, and in the case of FIG. 21, the lower end of the drain pipe 2120 is a silicone rubber hose Since it provides a pressing force from the inside of the (20) to the outside, there is an advantage of making the bonding state of the silicone rubber hose (20) more robust.

On the other hand, in the case of the embodiment of FIGS. 22 to 23 , a through hole 110a is formed in the bottom part 110 of the flowerpot body part 100 , and an outer diameter greater than the inner diameter d11 of the through hole 110a is larger. A hollow silicone rubber hose 22 having (d22) is inserted into the inner diameter surface of the through hole 110a to form a close-coupled state by elastic restoration, and the lower end of the drain pipe 3120 formed in a straight line is the It is inserted and installed on the inner surface side of the hollow part of the silicone rubber hose (22). Reference numeral 3130 denotes a drain control pipe inserted and coupled to the drain pipe 3120 , reference numeral 3120a denotes a first drain pipe hole, and reference numeral 3130a denotes a second drain pipe hole.

22 to 23, it is advantageous to construct a drainage system for supplying water by arranging a plurality of flowerpots 10 in the transverse and longitudinal directions, as will be described later with reference to FIG. 25 .
