Abstract

PROBLEM TO BE SOLVED: To provide a planting container preventing freeze or high-temperature drying of soil by performing heat insulation or heat radiation such that cold heat coming from a side face of the planting container or high-temperature heat by the irradiation of sunlight is not transferred to the planting soil inside the planting container.SOLUTION: A planting container includes: an inner wall provided between an outer wall and a soil space of the planting container; a gap serving as a movement passage allowing the vertically movement of air, provided between the outer wall and an inner wall; a communication port communicating outside air and the gap, provided at the lower end of the outer wall; and opening parts opening to the outside air, provided at the upper end of the gap. This configuration allows air to move upward or downward by cooling air or a temperature rise by high-temperature heat, and prevents transmission of the cold heat or high-temperature heat to soil by discharging it to the outside air.

Description

The present invention relates to a planting container capable of protecting a plant by protecting the temperature of the soil around the plant from an extremely low temperature in winter and an extremely high temperature in summer.

Conventionally, as a planting container, for example, if you look at a plant pot that you can see, plastic or unglazed pots are used, and the soil and the side of the container receive sunlight in the summer, the temperature rises, moisture Will evaporate and the plant will die out of water. In winter, the cold is received from the side of the container, the soil surface is cooled, the moisture of the soil freezes, and the plant is damaged.
In such a situation, there is a proposal of a double bowl, but it is not enough. Prior literature on double bowls can be shown below. FIG. 3 is a diagram illustrating examples of various conventional planting containers in a double pot.
Since it is a double pot, both are provided with an annular gap between the inner pot and the outer pot, but 3-A is shown in Patent Document 1, and aquatic plants such as water lilies Since it is an example of a water basin for planting, since the annular gap in the double basin also fills with water, the side surface of the outer basin has a through hole at a height position where the water is filled, and the water accumulates here. The inner pot has a large number of holes on both the upper side and the lower side of the height position of the through hole. The lower side is a hole filled with water, and the upper side is an air hole. It is not intended for temperature adjustment. 3-B is shown by patent document 2, and utilizes the air layer of a cyclic | annular space | gap as a heat insulation layer. Since air is not a good conductor of heat, the heat on the side of the bowl heated by sunlight is not transmitted quickly, but is slowly transmitted and eventually rises to the temperature on the side of the bowl. On the other hand, it is inconvenient that heat is difficult to escape. Although it is also described that the air portion is filled with a heat insulating material such as urethane foam, the situation is the same and inconvenient. Similarly to 3-B, 3-C to 3-D are the same in that the air in the annular gap does not move.
Patent Document 3 to Patent Document 4 show an annular gap in which the former is an expression that the upper end is closed, and the latter is a closed space that is used as an insulation space without air circulation. It shows that. In the latter, the drainage hole for overflow is provided below the side surface of the outer pot, but there is no hole for air circulation upward in order to aim at a closed space where air does not flow for heat insulation. The use of heat insulation has the same disadvantages as the 3-B example.
3-E and 3-F are similar to each other. In 3-B to 3-D, there are many air communication holes on the side surface of the inner pot, but 3-E and 3-F are the same. In order to supply this air, there is a vent hole in the outer pot for both the 3-E and 3-F examples. In 3-E, since the vent hole of the outer pot is intended to supply air to the soil in the inner pot, the vent hole is not present at the upper and lower ends of the side surface, and the size is not sufficient. It is not sufficient to cause heat dissipation by convection of air.
In 3-F, the vent hole on the side surface of the outer pot is sufficiently large, but since it is open in the vertical direction, the temperature is uniform in the vertical direction, and a temperature gradient is not formed or relaxed. Therefore, heat dissipation due to convection hardly occurs. Moreover, since the side surface of the inner pot is exposed at a portion that is widely opened as a ventilation hole, it causes inconvenience because it directly receives hot air from cold air or sun irradiation. In any of 3-A to 3-F, warm / cold heat coming from the side of the outer bowl actively moves air in and out of the upper and lower openings to carry the heat outside, preventing heat from being transmitted to the inner pot, No means of keeping warm is taken.

JP 2006-197885 A Registered utility model No. 3059615 JP 2003-61475 A JP2009-28194A Public Utility Model 1-140241 JP-A-8-23786

The object of the present invention is to prevent the freezing and high temperature drying of the soil by performing heat insulation or heat dissipation so as not to transmit the cold heat or solar heat from the side of the planting container to the planting soil in the planting container. It is to provide a planting container.

The planting container of the present invention has an inner wall between the outer wall of the planting container and the soil space, a gap that forms a movement path that allows air to move vertically between the outer wall and the inner wall, and an outer air and a gap at the lower end of the outer wall. By providing a communication port that communicates and an opening that opens to the outside at the top of the air gap, the air is moved upward or downward by cooling the air or raising the temperature by high-temperature heat, and discharging the cold or high-temperature heat to the outside air And preventing transmission to the soil. This will be described in the following claims.

Invention of Claim 1 is a planting container, Comprising: It has an inner wall provided in the standing state between the soil storage space and the outer wall facing the outside air in a standing state, and there is a gap between the outer wall and the inner wall The lower end of the outer wall is provided with a communication hole that communicates the gap and the outside of the outer wall, and the upper end of the gap is provided with an opening that opens to the outside from the gap. One of the communication hole and the opening is an air inlet and the other is an outlet, and the air gap is formed by cooling or increasing the density of the air by cooling or cooling with high temperature heat transmitted through the outer wall. By being a moving passage that moves downward or ascends, it is characterized in that cold air or high-temperature heat is discharged to the outside air as the air moves, and is prevented from being transmitted to the soil.

The invention according to claim 2 is the planting container according to claim 1, wherein the opening is provided in the upward direction of the gap.

The invention according to claim 3 is the planting container according to claim 1 or 2, characterized in that the opening is provided in a lateral direction of the gap.

Invention of Claim 4 is a planting container as described in any one of Claims 1-3, The said inner wall is a plate-shaped object, It is characterized by the above-mentioned.

The invention according to claim 5 is the planting container according to any one of claims 1 to 3, wherein the inner wall is a side wall of an inner pot provided in an outer pot, and the outer wall is the outer wall. It is a side wall of a pot.

The invention according to claim 6 is the planting container according to claim 5, wherein one of the outer pot and the inner pot is a pot made of earthenware, and the other is a pot made of plastic.

The invention according to claim 7 is a container for an outer pot of a planting container according to any one of claims 1 to 6, which is larger outside the inner pot by an amount corresponding to the gap, and The communication hole is provided.

Since it is configured as described above, the planting container according to the present invention is kept warm so that cold heat coming from the side of the planting container or high-temperature heat by irradiation of sunlight is not transmitted to the planting soil in the planting container. It is possible to dissipate heat and prevent soil freezing and high temperature drying.

It is a figure which shows one embodiment of the planting container of this invention. It is a figure which shows another embodiment of the planting container of this invention. It is a figure which shows the example of the conventional various planting containers in a double pot.

The planting container of the present invention has an inner wall between the outer wall of the planting container and the soil space, a gap that forms a movement path that allows air to move vertically between the outer wall and the inner wall, and an outer air and a gap at the lower end of the outer wall. By providing a communication port that communicates and an opening that opens to the outside at the top of the air gap, the air is moved upward or downward by cooling the air or raising the temperature by high-temperature heat, and discharging the cold or high-temperature heat to the outside air And preventing transmission to the soil.
This will be described below with reference to the drawings. The figure is a perspective view of a planting container, showing the front in cross section.

FIG. 1 is a diagram showing an embodiment of a planting container of the present invention. In this figure, it is assumed that the left elevation surface receives cold heat from the outside air, and particularly high temperature heat that has been irradiated with the sun.
Since the functions may be considered in the same way in the case of cold heat and in the case of high temperature heat, the following description will be made in the case of high temperature heat. On the left side, the outer wall 101 exposed to the outside air and the sun is an upright surface. In a normal planting container, the inside is entirely filled with soil, but between the soil 102 and the outer wall 101, The inner wall 103 is erected, and a gap 104 is provided between the outer wall 101 and the inner wall 103. A communication hole 105 is provided at the lower end of the outer wall 101 to communicate the outside and the gap 104. The communication hole 105 at the lower end is preferably a hole that is long in the length direction (lateral direction) of the planting container in order to improve air circulation by convection. Corresponding to the communication hole 105, the upper end of the gap 104 is provided with an opening 106 that is open to the outside and is long in the length direction (lateral direction) of the planting container. A support 107 may be provided between the outer wall 101 and the inner wall 103 for strength reinforcement. The communication hole 105 at the lower end, the gap 104, and the opening 106 at the upper end form a moving passage 108 for air to move upward. The communication hole 105 and the opening 106 provide a mouth for air to enter and exit. It promotes fluidity.
In such a configuration, when the outer wall 101 is warmed by the high temperature heat, the air in the gap 104 becomes high temperature and expands, the density becomes smaller and lighter, and the moving passage 108 is lifted and exits from the opening 106. , High temperature heat is discharged outside. Since the air pressure rises in the gap 104 due to the rise of air, air having a temperature lower than that of the air in the gap 104 enters from the outside through the communication hole 105 and prevents the temperature from becoming high. Therefore, the soil 102 can be prevented from drying at a high temperature. In the example of FIG. 1, the inner wall is a plate-like body.

FIG. 2 is a diagram showing another embodiment of the planting container of the present invention.
2-A has a long planter in the lateral direction, and 2-B has a circular bowl shape. Unlike Figure 1,
Cold heat and high temperature heat are examples that come from the entire sidewall of the container. Both the outer pot having the outer wall and the inner pot having the inner wall are set integrally as shown in the figure at the time of use, but may be removable. The concave portion 202 of the inner pot 201 is a space where the soil enters, but the soil is not shown here. A drain hole 204 is provided on the bottom surface 203 of the inner pot 201. The inner pot side wall 205 which is the side wall of the inner pot 201 may have an air hole for supplying air to the soil. The inner pot 201 is arranged in the outer pot 210 as shown in the figure, and a gap 212 is provided between the inner pot side wall 205 and the outer pot side wall 211 that is the side wall of the outer pot.
A communication hole 213 that communicates the outside and the gap 212 is provided at the lower end of the outer pot side wall 211. The communication hole 213 at the lower end is preferably a hole that is long in the length direction (lateral direction) of the planting container in order to improve air circulation by convection. Corresponding to the communication hole 213, the upper end of the gap 212 is provided with an opening 214 that is open to the outside and is long in the length direction (lateral direction) of the planting container. A support body 215 may be provided between the outer pot 210 and the inner pot 201. The communication hole 213 at the lower end, the gap 212, and the opening 214 at the upper end form a moving passage 216 for air to move upward. The communication hole 212 and the opening 214 provide a mouth for air to enter and exit. It promotes fluidity. In the case of cold air, the air moves down the movement passage 216.
In such a configuration, when the outer basin side wall 211 is heated by the high temperature heat, the air in the gap 212 becomes high temperature and expands, the density becomes smaller and lighter, and the moving passage 216 is lifted and is released from the opening 214. Out, high temperature heat is discharged outside. Since the air in the gap 212 becomes low pressure due to the rise of air, air having a temperature lower than that of the air in the gap 212 enters from the outside through the communication hole 213 and prevents the air from becoming hot. For this reason, the soil (not shown) in the inner pot can be prevented from drying at a high temperature. If the opening 214 is at the upper end of the gap 212, various changes can be made even when it is provided on the side surface of the outer pot.

Since 2-B is a circular pot, the difference from 2-A is that the communication hole 213 is a long hole in the length direction (lateral direction) of the planting container and the length direction (horizontal) of the planting container. The opening 214 that is long in the direction) is the same except that the opening 214 is long in the circumferential direction of the circular bowl.
A round bowl is shown in 2-C. The inner pot can be easily realized by using a commercially available ordinary single pot and preparing an outer pot that is slightly larger than the gap, which is very convenient. If a communication port is provided at the bottom, since it is slightly larger than the gap, it becomes an opening as it is, and the 2-C state can be realized very easily. Of course, we are not particular about circular bowls.

In each example, the communication hole 213 and the opening 214 are described as being long in the length (lateral) direction of the container. However, even if many holes are provided in the length direction, the communication hole 213 and the opening 214 are effectively the same.

Furthermore, it is advantageous to make one of the outer pot and the inner pot made of ceramics such as unglazed and the other made of plastic because of the following characteristics.
If the outer bowl is made of plastic, the inner pot made of ceramics does not come out, so it is easy to protect from destruction.
Plastic outer pots are advantageous for complex formation of communication ports and openings. Plastic outer pots are made white to reflect sunlight and do not easily reach high temperatures. Since the surface of the inner pot does not face the outside, there is an advantage that the temperature is difficult to rise.
If the inner pot is made of plastic, it looks good because the pottery is on the outside.

As described above, the planting container according to the present invention performs heat insulation or heat dissipation so that cold heat coming from the side of the planting container or high-temperature heat by irradiation of sunlight is not transmitted to the planting soil in the planting container. Since it is possible to prevent freezing and high temperature drying, industrial applicability is extremely high.
