TECHNICAL FIELD OF THE INVENTION
The present invention relates to a plant stand having an air purifying function, that is, a plant stand for purifying air by passing air through natural or artificial soil holding plant roots, and a replaceable flower pot used for the plant stand. Things.
[0002]
[Prior art]
It is known that microorganisms that grow in the soil where certain types of plants are planted decompose or destroy toxins in the air, and a planting stand that purifies indoor air using this has been proposed. For example, the one proposed in Japanese Patent Application Laid-Open No. 2000-166388 includes a flowerpot 51, a water container 52 that houses the flowerpot 51, and a fan 53 that allows air to pass through the soil of the flowerpot 51. The flower pot 51 has a water hole 54 on the bottom surface and a plurality of air holes 55 at the same height on the upper peripheral wall. The water container 52 is provided with an opening for inserting a flower pot on the upper surface, and supports the inserted flower pot with a space around and at the bottom thereof. An intake port of an intake pipe 56 of the fan 53 opens at an upper part of the water container 52. A ring-shaped flexible seal 57 having an inner peripheral edge or an upper edge that is in contact with the outer periphery of the inserted flower pot 51 is provided at an upper portion of the water container 52.
[0003]
At the plant stand, a flower pot 51 into which a plant is planted is inserted into a water container 52, and when water is poured into the flower pot, excess water flows out of the water hole 54 into the water container 52, and the water level is confirmed by a water level gauge 58. it can. When the fan 53 is rotated, the indoor air is sucked from the upper surface of the soil of the flowerpot, passes through the soil, passes through the air hole 55, passes through the upper part of the water container and the suction pipe 56, and is sucked into the fan 53 again. Released into the room. When replacing a flowerpot, it is only necessary to take out the flowerpot 51 and replace it with a flowerpot in which a new plant is planted.
[0004]
The planting stand having the above structure has a small installation space, and can exchange plants with a simple operation. The plant stand described in this publication also includes a light source (incandescent lamp) 59 that illuminates plants planted in flower pots to promote photosynthesis and sterilizes air exhausted from the fan 53 into the room.
[0005]
Further, this publication describes a protection means for preventing the soil put in the flower pot 51 from spilling out of the water hole 54 and the air hole 55. As protection means for the air holes 55, it is shown that a number of small holes are provided so that soil does not flow out, a filter having a mesh structure is attached, and a shielding flange is provided inside the air holes like an eaves.
[0006]
A similar plant stand is described in Registered Utility Model No. 3041734. The utility model publication is disclosed in Japanese Patent Application Laid-Open No. H11-163873 in that the water container referred to in the above structure is filled with soil, and that the perimeter and the entire bottom surface of the flower pot are provided with through holes for allowing air or water to pass therethrough. It is different from that described in JP-A-2000-166388.
[0007]

Registered Utility Model No. 3041734
[Problems to be solved by the invention]
The water stored in the bottom of the water container 52 is supplied to the soil filled in the flowerpot of the flowering stand described in JP-A-2000-166388, and when the fan 53 is operated, air is supplied as shown in FIG. Flows from the upper opening of the flowerpot through the gap in the soil to the air holes 55, and when passing through the soil, microorganisms in the soil purify the air. In order to effectively purify indoor air, the amount of air passing through the soil should be increased.However, when the air passes through the soil, it deprives the soil of moisture, When air flows, water required for plant growth is deprived of soil, thereby inhibiting plant growth and causing the plants to wither and die.
[0009]
To avoid this problem, the fan 53 may be operated intermittently to prevent excessive transpiration of water in the soil, or by allowing air to pass only through the upper part of the soil away from the roots of the plant. Make sure that the soil where the roots grow is not dry. However, all of these methods reduce the air purification effect of microorganisms in the soil.
[0010]
Further, in the registered utility model publication No. 3041734, since the soil is also filled in the water container around the flowerpot, it is necessary to dig the soil around the flowerpot when replacing the plant with the flowerpot. Yes, the replacement work of the flower pot is more troublesome than the one in which the soil is not filled around the flower pot.
[0011]
According to the present invention, the flower pot can be replaced without digging the soil around the flower pot, and a large amount of air can be passed through the soil containing a large amount of water, which is rich in microorganisms that purify the air and inhabits the air. It is an object of the present invention to obtain a planting stand having an air purifying function that can effectively perform air purifying, does not cause the plants to wither and die even by continuous passage of air, and is easy to maintain.
[0012]

The flower pot 1 is planted in the flower pot at a height lower than the outer wall 2. A partition wall 6 having no air permeability which is divided into a planting section 4 and a ventilation section 5; and the ventilation section 5 and the upper space 15 at a position lower than the upper edge of the partition wall and higher than the water level of the water stored in the water container 21. And a water hole 7, 7a, 8b communicating the planting part 4 and the ventilation part 5 with the bottom of the water container 21 at a position lower than the level of the water stored in the water container. It has.
[0013]
The planting stand having an air purifying function according to the second aspect of the present invention comprises a water container 21 for storing water at the bottom, a top portion of the water container closed with the bottom immersed in the water contained in the water container. And a fan 25 communicated with the upper space 15 of the water container in a state where the water pot is separated from the plant. A partition wall 6 having no water permeability, a water hole 7 communicating below the surface of the water contained in the water container 21 with the planting part 4 and the bottom of the water container 21, and a ventilation with the planting part 4 under the water surface. Water holes 7, 7 a, 8 b communicating with the portion 5, and a ventilation hole formed at a position immediately above the surface of the water contained in the water container 21 and communicating the ventilation portion 5 with the upper space 15 of the water container. 8a, wherein the water holes and the air holes are provided to prevent leakage of soil in the flowerpot. Comprising a stage, soil the plant 栽部 4 and vent 5 flowerpot 1 is characterized in being filled.
[0014]
The flowerpot according to claim 3, which is used for the flowerpot according to the present invention, has a height lower than the outer wall 2 and partitions the inside of the flowerpot into a planting portion 4 at the center and a ventilation portion 5 at the periphery. 6, a vent 8a penetrating the outer wall at a position lower than the upper edge of the partition, and a bottom plate 3 of the pot, the bottom of the partition and / or the bottom of the outer wall penetrating the bottom of the pot at a position lower than the vent. Water holes 7, 7a, and 8b are provided for communicating the planting section 4 and the ventilation section 5 with the outside of the pot.
[0015]
Further, the flowerpot according to the invention of claim 4 has a non-permeable partition wall 6 that divides the inside into a planting part 4 and a ventilation part 5, a water passage hole 7 penetrating the bottom plate 3 of the planting part 4, A water hole 7, 7a, 8b communicating the planting part 4 with the ventilation part 5 at the bottom of the pot, and a ventilation hole 8a communicating the ventilation part 5 and the outside of the pot at a position higher than these water holes. The soil is filled in the planting part 4 and the ventilation part 5 of the flowerpot 1.
[0016]
The water holes 7, 7a and 8b of the flowerpot having the above structure are provided at the bottom of the partition 6, provided at the bottom of the planting section 4 and the ventilation section 5, and provided at the bottom of the planting section and the bottom of the side wall of the ventilation section. It is possible to provide these in an overlapping manner or in combination. The ventilation holes 8a are preferably provided in the lower part of the outer wall in the form of slits in the up-down direction, or as a large number of small holes distributed vertically and horizontally. As for the slits or small holes provided in this way, those below the surface of the water contained in the water container are water passage holes, and those above the water surface are vent holes. The height of the partition wall 6 is preferably lower than the outer wall 2 so that the partition wall does not appear on the upper surface of the soil when the pot is filled with the soil.
[0017]
The soil on which the above-ground plants take root needs to retain water and air. When a common ground plant is kept in a state where the roots are submerged for a long time, roots rot and die. In the soil of the flower pot whose bottom is immersed in water, the water sucked up by the capillary action is held together with the air. If air is allowed to pass through the soil holding water and air in such a state, the water evaporates and the water content of the soil decreases, and the roots of the plant cannot absorb sufficient water.
[0018]
In the plant stand of the present invention, when the fan 25 is operated to allow room air to pass through the soil of the plant pot 1, the air does not pass through the center or the planting portion of the plant pot defined by the partition 6. The water in the soil at the central part or planting part where the roots of the plant extend is not taken away by the passing air, and the plant does not wither and die due to drying of the soil even when a large amount of air is constantly passed.
[0019]
On the other hand, the organic matter and the propagated microorganisms generated in the central part or the planting part diffuse in the water and are active in the soil in the peripheral part or the ventilation part. In the soil above the water surface of the ventilation part, moisture is removed one after another by the passing air, and new water rises into the soil by capillary action. By this action, the air passing through the peripheral part or the ventilation part is always subjected to the action of microorganisms in the soil, and an effective air purification action can be obtained.
[0020]
It is preferable that the air be passed through the soil as close to the water surface as possible. Therefore, it is desirable that the ventilation hole 8a be opened directly above the water surface of the water stored in the water container 21. Since this water surface rises and falls due to repetition of water supply and transpiration, if a vertical slit or small holes dispersed vertically and horizontally are provided in the lower part of the outer wall 2, those above the water surface function as ventilation holes. Even when the water surface goes up and down, the most preferable ventilation state can be obtained.
[0021]
The height of the partition wall 6 is preferably a height that does not appear on the surface of the soil filled in the flower pot 1, and a water hole is provided at the bottom of the partition wall 6 for smooth movement of organic substances and microorganisms. Is considered preferable.
