Description

The present invention relates to greenhouses, and more particularly to greenhouses that store foaming liquids and improve heat insulation and heat retention by generating bubbles.

A greenhouse is a building where plants can be cultivated freely by artificially controlling light rays, temperature, humidity, etc. Such greenhouses allow sunlight and solar heat to pass through by surrounding the outer surface of a single-layer skeleton with a transparent material such as synthetic resin film or glass, and keep the internal temperature high because external air does not flow into the interior. You can also do it. In the greenhouse, the plants can be cultivated all year round and the harvest time of the plants can be adjusted.

On the other hand, the outside temperature is low in winter, and the greenhouse has a low internal temperature due to the loss of internal heat. In addition, in the summer, greenhouses have an internal temperature that is higher than necessary due to intense direct rays and high external temperatures. As a result, heating equipment (for example, fireplace, boiler, etc.) or cooling equipment (for example, air conditioner, etc.) is installed in the greenhouse, and the internal temperature of the greenhouse is maintained at an appropriate level. However, each such facility requires considerable installation and maintenance costs.

In addition, a heat insulating cover may be applied to the greenhouse. The thermal insulation cover covers the greenhouse by being located on the outer surface of the greenhouse and provides the greenhouse with heat insulation and shading functions. Such a thermal cover can be easily applied to a relatively small greenhouse, but when applied to a relatively large greenhouse, it is cumbersome to unfold and then fold. A separate mechanical device is installed on the heat insulating cover of a relatively large greenhouse so that the heat insulating cover can be unfolded and then folded. However, since the heat insulating cover has a large volume, it may not be folded after being smoothly unfolded by a mechanical device, and may not operate normally when it snows or rains.

The greenhouse is composed of double structures, and a protective layer may be formed between the structures. The protective layer is filled with air to provide temperature control and heat retention effects. Since it is difficult to achieve the effects of temperature control and heat retention using only air, the protective layer may be filled with air bubbles. Generally, bubbles are created using foaming liquid and air. However, the bubble generator has a complicated structure for supplying and recovering the foaming liquid.

Hereinafter, each embodiment according to the technical idea of the present invention will be described in detail in order.

FIG. 1 is a perspective view showing a greenhouse 100 according to a preferred embodiment of the present invention, and FIG. 2 is a perspective view showing a state in which the frame bag portion 103 of the greenhouse 100 shown in FIG. 1 is filled with air bubbles. FIG. 3 is a diagram showing a state in which the bubble generating portion 105 is coupled to the inside of the frame bag portion 103 in the greenhouse shown in FIG. 1, and FIG. 4 is a diagram in which the greenhouse 100 shown in FIG. 1 is closed by the opening / closing portion 106. FIG. 5 is a diagram showing a state in which the greenhouse 100 shown in FIG. 1 is opened by the opening / closing portion 106.

As shown in FIGS. 1 to 5, the greenhouse 100 according to a preferred embodiment of the present invention includes an inner frame portion 101, an outer frame portion 102, a frame bag portion 103, a bag support portion 104, and a bubble generating portion 105. The state of the frame bag portion 103 is controlled by the external environment of the greenhouse 100. The bubble generating section 105 generates bubbles inside the frame bag section 103, fills the frame bag section 103 with the bubbles, and controls the heat insulation and heat retention performance of the greenhouse 100.

The inner frame portion 101 is located on the ground while forming the cultivation space 100a. The cultivation space 100a has a tunnel shape and accommodates each plant. 1 and 2 show that such a cultivation space 100a has a tunnel shape, but is not limited to this, and can have various shapes (for example, a dome shape) if each plant can be accommodated. .. Further, the internal frame portion 101 is composed of a framework.

The outer frame portion 102 is located on the ground, is located outside the inner frame portion 101 while being separated from the inner frame portion 101, and corresponds to the inner frame portion 101. The outer frame portion 102 also has a frame like the inner frame portion 101.

Further, the outer frame portion 102 is covered with a frame cover manufactured of a synthetic resin film or the like, and the frame cover can maintain the cultivation space 100a in a closed state. On the other hand, since the frame cover can be folded and then unfolded as needed, it can be used to open and close the cultivation space 100a.

The internal frame portion 101 as described above includes the wall frame portion 111 and the roof frame portion 113, and the outer frame portion 102 includes the wall frame portion 121 and the roof frame portion 123. Since the inner frame portion 101 and the outer frame portion 102 have the same configuration except that they differ in size and position, the present embodiment includes the wall frame portion 111 and the roof frame included in the inner frame portion 101. Part 113 will be described.

The wall frame portions 111 are paired and are located on the ground along the length direction of the cultivation space 100a. The cultivation space 100a is located between the frame portions 111 of each wall body.

The roof frame portion 113 connects the upper ends of the wall frame portions 111 to each other. The roof frame portion 113 is located so as to close the upper surface of the cultivation space 100a, and has an arch shape.

On the other hand, the wall frame portion 121 and the roof frame portion 123 of the outer frame portion 102 are located so as to correspond to the wall frame portion 111 and the roof frame portion 113 of the inner frame portion 101, respectively.

The frame bag portion 103 is located between the inner frame portion 101 and the outer frame portion 102, and has a closed storage space 103a. The frame bag portion 103 can be expanded or contracted. Such a frame bag portion 103 may have a form of a bag manufactured of a synthetic resin film, or may have a form of joining a pair of synthetic resin films.

The foaming liquid is stored in the storage space 103a. At this time, the foaming liquid occupies the lower part of the storage space 103a. The upper part of the storage space 103a is vacant. Further, a part of the bubble generating portion 105, which will be specifically described later, is inserted into the lower portion of the storage space 103a to come into contact with the foaming liquid. The bubble generation unit 105 supplies air to the lower part of the storage space 103a and brings the air into contact with the foaming liquid. At this time, bubbles are generated in the storage space 103a, and the bubbles are filled in the upper part of the storage space 103a. Here, the bubbles are an aggregate of air bubbles, and after a certain period of time, they change into an effervescent liquid while calming or tearing at the upper part of the storage space 103a. Such an effervescent liquid can be guided to the lower part of the storage space 103a and generate bubbles in the storage space 103a. Here, the effervescent solution is a solution in which a solute such as soap solution, glycerin, starch syrup, or sugar is dissolved in a solvent such as water. By adjusting the amount of solute in the effervescent solution, the bubbles can be maintained for 1 hour or more after being generated from the effervescent solution.

For example, when air is supplied to the storage space 103a, the frame bag portion 103 expands and comes into close contact with the inner frame portion 101 and the outer frame portion 102, and closes between the inner frame portion 101 and the outer frame portion 102. .. Since the foaming liquid is stored in the lower part of the storage space 103a, the foaming liquid generates bubbles while being in contact with air. As a result, the frame bag portion 103 provides a function as a heat insulating and heat insulating layer for the greenhouse 100 by combining the air supplied to the storage space 103a and the bubbles generated in the storage space 103a. Further, the frame cover covering the outer frame portion 102 protects the frame bag portion 103 by blocking the wind generated outside the greenhouse 100, and the frame bag portion 103 can be maintained in a certain form.

On the other hand, when the frame bag portion 103 is contracted, the air bubbles change to foaming liquid while being calmed or torn and are stored in the lower part of the storage space 103a, and the air is discharged from the upper part of the storage space 103a. As a result, the heat insulating and heat insulating layer for the greenhouse 100 is reduced.

Further, the frame bag portion 103 includes a wall body bag portion 131 and a roof bag portion 133.

The wall bag portion 131 forms a storage space 103a so as to correspond to the wall frame portions 111 and 121, and the roof bag portion 133 forms a storage space 103a so as to correspond to the roof frame portions 113 and 123. At this time, the wall bag portion 131 and the roof bag portion 133 are separated from each other, and the upper surface of the wall bag portion 131 is located so as to be adjacent to the side surface of the arch-shaped roof bag portion 133.

Further, a bag opening / closing portion 103b is installed in the frame bag portion 103. The bag opening / closing portion 103b opens / closes the storage space 103a of the frame bag portion 103.

When heat retention is required, the bag opening / closing portion 103b closes the storage space 103a. At this time, when air is supplied to the storage space 103a, the frame bag portion 103 is expanded by the air, and bubbles are generated in the storage space 103a. Further, the internal pressure of the frame bag portion 103 increases.

When the internal pressure of the frame bag portion 103 exceeds a set value due to air and air bubbles, the bag opening / closing portion 103b is opened and air is discharged to the outside of the frame bag portion 103. That is, the air is discharged from the storage space 103a of the frame bag portion 103 via the bag opening / closing portion 103b. At this time, the internal pressure of the frame bag portion 103 decreases. Further, when air is discharged from the storage space 103a of the frame bag portion 103 and the internal pressure of the frame bag portion 103 reaches a set value, the bag opening / closing portion 103b is closed. On the other hand, when the frame bag portion 103 is contracted, the bag opening / closing portion 103b is opened and air is discharged from the storage space 103a of the frame bag portion 103. Therefore, the bag opening / closing portion 103b can adjust the internal pressure of the frame bag portion 103 and prevent the frame bag portion 103 from being excessively expanded and damaged by air and air bubbles.

Here, the bag opening / closing portion 103b is in the form of a thin and flexible vinyl hose, can be closed in a folded state, and can be opened while being released from the folded state. When the internal pressure of the frame bag portion 103 exceeds the set value, the bag opening / closing portion 103b is opened while being expanded, and air can be discharged from the storage space 103a through the bag opening / closing portion 103b. Further, when the internal pressure of the frame bag portion 103 reaches a set value, the bag opening / closing portion 103b is closed while being folded, and the storage space 103a is closed. At this time, the air is not discharged from the storage space 103a. Since the bag opening / closing portion 103b is in the form of a thin and flexible vinyl hose, the opening / closing of the storage space 103a can be realized at a low cost.

Further, in order to prevent the foaming liquid from being discharged by the bag opening / closing portion 103b while the frame bag portion 103 stores the foaming liquid, the bag opening / closing portion 103b is preferably installed at the upper end portion of the wall body bag portion 131 to cover the roof bag. It is installed on the upper surface of the upper part of the portion 133. That is, the bag opening / closing portion 103b is installed on the upper portion of the wall body bag portion 131 and the upper portion of the roof bag portion 133, and is used for discharging air.

The bag support portion 104 supports the frame bag portion 103 between the inner frame portion 101 and the outer frame 102. Further, the bag support portion 104 is bent so as to form a predetermined space, and is located along the length direction of the cultivation space 100a. At this time, since the frame bag portion 103 is in a state of storing the foam liquid, the portion of the frame bag portion 103 that stores the foam liquid can be placed on the bag support portion 104. As a result, the frame bag portion 103 can be maintained in a state in which the foamed liquid is stably stored by the bag support portion 104. Further, the bag support portion 104 includes a wall body bag support portion 141 and a roof bag support portion 143.

The wall bag support portion 141 is located on the ground between the wall frame portion 111 of the inner frame portion 101 and the wall frame portion 121 of the outer frame portion 102, and supports the lower surface of the wall bag portion 131. The wall bag portion 131 is placed on the wall bag support portion 141.

The roof bag support portion 143 is supported by the wall frame portion 111 of the inner frame portion 101 and the wall frame portion 121 of the outer frame portion 102, and the roof frame portion 113 of the inner frame portion 101 and the roof frame portion of the outer frame portion 102. It is located between 123. The lower surface of the roof bag portion 133 is supported by the roof bag support portion 141. The contracted roof bag portion 133 is mounted on the roof bag support portion 143, while the expanded roof bag portion 133 is mounted only on the lower portion thereof on the roof bag support portion 143. That is, the lower portion of the roof bag portion 133 is maintained in a state of being placed on the roof bag support portion 143.

The bubble generating section 105 is connected to the frame bag section 103, supplies air to the storage space 103a of the frame bag section 103, and generates bubbles from the foaming liquid stored in the lower part of the storage space 103a. The generated bubbles fill the upper part of the storage space 103a to provide a heat insulating and heat retaining effect for the greenhouse 100. Further, the bubble generating section 105 includes a supply piping section 151, a connecting piping section 152, and an air supply section 153.

The supply piping portion 151 is tubular and is inserted into the storage space 103a of the frame bag portion 103. In particular, the supply piping section 151 is located below the wall bag section 131 and below the roof bag section 133. Further, the supply piping portion 151 is immersed in the foaming liquid stored in the frame bag portion 103, that is, the foaming liquid in the storage space 103a.

A plurality of supply holes 151a are formed on the outer peripheral surface of the supply piping portion 151. The supply hole 151a connects the inside and the outside of the supply piping section 151. Here, the supply hole 151a is formed along the length direction of the cultivation space 100a.

The supply piping portion 151 may be in the form of a vinyl tube. As a result, the supply piping section 151 can be easily transported for installation in the frame bag section 103. Further, since the supply piping portion 151 is made of vinyl, it is not maintained in a state of being immersed in the foaming liquid of the storage space 103a, and may float on the surface of the foaming liquid. Here, a guide shaft (not shown) can be inserted into the supply piping section 151. As a result, the supply piping section 151 can come into contact with the bottom surface of the storage space 103a and be maintained in a state of being immersed in the foaming liquid.

The connecting piping section 152 is connected to one vertical section of the supply piping section 151. Here, the connecting piping portion 152 is located so as to be adjacent to the bag supporting portion 104. For example, when the supply piping portion 151 is inserted in the lower part of the wall body bag portion 131, the connecting piping portion 152 is located in the lower part of the wall body bag portion 131 so as to be adjacent to the wall body bag support portion 141. It is connected to 151. Further, when the supply piping portion 151 is inserted into the lower part of the roof bag portion 133, the connecting piping portion 152 is connected to the supply piping portion 151 located in the lower part of the roof bag portion 133 so as to be adjacent to the roof bag support portion 143. Will be done.

The air supply unit 153 is connected to the connecting piping unit 152 and is located outside the frame bag unit 103 and outside the cultivation space 100a. The air supply unit 153 supplies air to the supply pipe unit 151 via the connecting pipe unit 152. At this time, after being supplied to the supply piping section 151, the air passes through the supply hole 151a and is combined with the foaming liquid while being divided and deformed into the form of air bubbles by the supply hole 151a. As a result, bubbles are generated and filled in the storage space 103a of the frame bag portion 103.

On the other hand, the air bubbles filled in the upper part of the storage space 103a change into an effervescent liquid while calming or tearing, and the effervescent liquid is guided to the lower part of the storage space 103a and stored as it is inside the frame bag portion 103. When the air supply unit 153 supplies air to the supply piping unit 151, such an effervescent liquid can be used to generate bubbles again by the air and fill the upper part of the storage space 103a with the bubbles.

The bubble generation unit 105 of the present embodiment generates air by supplying air to the foaming liquid in the storage space 103a, and fills the upper part of the storage space 103a with air bubbles. The foaming liquid changed from the bubbles is guided to the supply piping section 151 of the bubble generating section 105 and can be used again to generate the bubbles. That is, the bubble generating section 105 can be used in combination with the frame bag section 103 to continuously generate bubbles from the foamed liquid in the storage space 103a.

In the greenhouse 100 of the present embodiment as described above, the frame bag portion 103 stores the effervescent liquid in a state of being supported by the bag support portion 104. The bubble generating section 105 is inserted into the frame bag section 103 and supplies air to the storage space 103a of the frame bag section 103. At this time, the air generates bubbles from the foamed liquid while passing through the supply hole 151a of the supply piping section 151 of the bubble generating section 105. Such bubbles are filled in the upper part of the storage space 103a. Further, the bubbles are calmed down or torn in the upper part of the storage space 103a and changed to the foaming liquid, and the foaming liquid is stored in the lower part of the storage space 103a. Such foaming liquids can be used to generate bubbles again.
