Description

Detailed Description of the Invention (Technical Field) The present invention relates to an air tent that is formed by increasing internal pressure by blowing air from a blower, and is used for growing plants such as fruit trees, vegetables, and ornamental plants, or for growing seaweed and grains. , relates to an air tent house that is also used for drying objects such as fish.

(Prior Art) Conventionally, in order to grow plants, so-called vinyl greenhouses, in which pillars and frames are assembled on the ground and vinyl is stretched over the pillars and frames, are often used. In this vinyl house, it is extremely troublesome not only to assemble the pillars and frames on the ground, but also to attach vinyl to the pillars and frames after assembly is completed. In addition, in this type of greenhouse,
The greenhouse is equipped with a blower with a heater 12' for exchanging the air inside the greenhouse or heating the room, and usually this blower with a heater 12' is installed outside the greenhouse, as shown in Figure 3. has been done. This is the blower with heater 12'
However, not only is there a dead space 16 on the land on both sides of the heater-equipped blower 12' as shown in FIG. 12' is exposed directly, causing damage to it quickly. Further, if the heater-equipped blower 12' is operated, the noise generated by the blower 12' may directly affect the surrounding area and cause noise pollution.

As mentioned above, if a part of the blower is exposed outside the house, it may cause noise or be damaged quickly by rain, etc.
Judging from Figure 4 of that publication, it is thought that the same problem occurs in the "air tent" proposed in Publication No. 37-12660.
Judging from Figures 1 and 3 of the publication, it is thought that the same problem occurs in the "plant growth support device" proposed in Publication No. 135128.

In that case, as shown in Figure 1 of Publication of Utility Model Publication No. 49-3448, it is conceivable to install a blower inside the greenhouse, but even if the above-mentioned problems with the blower itself are solved, the In order to create an air tent house for growing or drying, more thorough consideration is required. This is because it is meaningless unless you consider how to create conditions that are good for drying and growing plants. This is because simply piping a blower into an air house and attaching an automatic metering damper for wind resistance is unlikely to fully satisfy the drying and plant growth conditions.

(Purpose) The present invention has been made to solve the above problems.The purpose of the present invention is to provide an extremely simple structure and installation work, and to eliminate problems such as dead space, damage caused by rain, noise generation, etc. To provide an air tent house which can solve the above problems and satisfy good conditions for drying and plant growth.

(Structure) The present invention has been made to achieve the above-mentioned objects, and the gist of the invention can be explained using the reference numerals used in the examples. An air tent 11 which is airtightly enclosed to form a house; an air blower 12 and an auxiliary air blower to which a suction duct is connected to an opening formed in the air tent 11 and which are entirely disposed at the lower part of the air tent 11; 14, a heating device 12c provided in the blower 12 to selectively heat the outside air taken in from the intake duct, and a discharge port provided in the air tent 11 to discharge excess outside air from each blower 12 and the auxiliary blower 14. 13, the discharge port 13 and the entrance/exit 15 are arranged on the opposite side of the blower 12, and the auxiliary blower 14 is connected to the blower 12.
and a discharge port 13, and the air supply ducts of the blower 12 and the auxiliary blower 14 are directed toward the discharge port 13.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a front view and a plan view of an air tent 10 according to the present invention, respectively. There is. This air tent house (hereinafter simply referred to as a house) 10 includes an air tent 11 installed on the ground, two blowers 12, 12 installed inside this air tent 11, and this blower 1.
The air tent 11 is provided with a plurality of exhaust ports 13 to 13 provided in a portion of the air tent 11 located on the opposite side of the air tent 2.

The air tent 11, as shown in FIG.
It surrounds the entire part of the cage-like pedestal 18 where the plants P are planted or the items to be dried are arranged,
A net 11 is attached to the foundation cloth 11a that is buried and fixed underground.
b, and a film 11c made of an airtight synthetic resin or the like is formed inside the net 11b.
It is formed by arranging.

Each blower 12 includes a suction duct 12a, a fan 1
2b and the heating device 12c are compactly assembled, and as shown in FIG. 4, the whole is installed at the lower part of the air tent 11 as described above. Intake duct 12 of this blower 12
a is airtightly connected to an opening provided in a part of the film 11c of the air tent 11, and a heater 12 is installed in front of the fan 12b of the blower 12.
c are consecutively provided. As a result, each blower 12
The outside air is introduced into the house 10 from the suction duct 12a by operating a fan 12b, and the introduced air is fed into the house 10 while being selectively heated by operating the heater 12c. .

Each outlet 13 is formed at a position farthest from each blower 12, and a lid and a mesh having a mesh size to prevent insects from entering and exiting are attached to the opening.

Furthermore, as shown in FIGS. 1 and 2, a total of four auxiliary blowers 14 to 14 are provided at the lower part of the inside of the house 10 located between each blower 12 and each outlet 13. ing. Each auxiliary blower 1
Similar to the blower 12 described above, the air intake duct 4 is connected from the inside to an opening formed in a part of the film 11c of the air tent 11. It is open towards.

In this embodiment, each blower 12, its heater 12c, and each auxiliary blower 14 are all electrically operated, and their selective operation is controlled by the house 1.
The operation can be appropriately controlled by a control panel (not shown) placed in or near the entrance/exit 15 created on the left side.

(Function) In the tent 10 configured as above,
It is assembled and used as follows. first,
The base cloth 11a of the air tent 11 is buried in a predetermined position, and each blower 1
2 and an auxiliary blower 14 are arranged. Then, a net 11b is connected to the base cloth 11a, and a film 11c is placed inside the net 11b. Next, the intake ducts of each blower 12 and the auxiliary blower 14 are connected airtightly to each opening of the film 11c, and the entrance/exit 15 is connected to the air tent 11.

In this state, if each exhaust port 13 is closed and each blower 12 and each auxiliary blower 14 are operated to introduce outside air into the air tent 11, the air tent 11 will be expanded as shown in FIG. A house 10 is formed. After the inside of the house 10 reaches a predetermined pressure, each outlet 13 is opened. Note that if each heating device 12c is operated when this outside air is introduced, the house 10 can be immediately formed as a greenhouse at a predetermined temperature.

In addition, in this house 10, each blower 1
2 and the selective operation of each auxiliary blower 14, it is possible to form a steady flow of air within the house 10, thereby bringing the air temperature within the house 10 to a temperature suitable for the growth of the plants P. Not only can the air inside the house 10 be kept fresh, but also the plants P themselves can be stimulated by the wind. Therefore, the growth and fruit set rate of plants can be improved compared to conventional greenhouses.

One of the major reasons why the present invention improves plant growth and fruit set rate is that a steady flow of air is formed within the house 10, in other words, a breeze is constantly blowing inside the house 10. There is a particular thing.
That is, in the house 10 according to the present invention,
Each blower 12 and the auxiliary blower 14 are all provided at the bottom of the air tent 11, and the exhaust port 13
Since the air blowers 12 were installed on the opposite side of these, each blower 12
A breeze is created by the outside air taken in from the auxiliary blower 14. this house 10
The breeze inside provides the plants P with the stimulation necessary for their healthy growth.

Of course, if the screen-like pedestal 18 is arranged horizontally in the house 10 and dried materials such as seaweed and grains are arranged on it, the dried materials will be exposed to wind at a temperature higher than the outside temperature. By being blown onto the drying material, the material to be dried can be dried within a short period of time without degrading the taste or damaging the material. In this case, if the screen-like pedestal 18 is located above the air ducts of each blower 12 and the auxiliary blower 14, and each outlet 13 is provided above the screen-like pedestal 18, the above-mentioned drying can be made more effective. It can be done.

In addition, under strong winds, adjustment of the air volume of each blower 12 and each auxiliary blower 14 and each outlet 13
By closing the tent 10, the internal pressure inside the tent 10 is increased. As a result, the house 10 can have increased rigidity even without pillars and can withstand strong winds.

(Effects) Since this house 10 is as described above, its assembly and disassembly operations can be performed extremely easily. That is, in this house 10, each device is connected to the lower part of the air tent 11, and no heavy objects are attached to the upper part, so the work of inflating and storing each air tent is easy. It can be done easily.

Further, in this house 10, as shown in FIGS. 1 and 2, each blower 12 and each auxiliary blower 14 do not protrude outside the air tent 11 at all. Therefore, the house 10 according to the present invention
Unlike the conventional house 10', there is no dead space 16, and it can be provided close to the lot line or ridge 17 of the divided land. Furthermore, since each blower 12 and each auxiliary blower 14 are entirely housed within the house 10, the air tent 11 blocks out noise generated from these blowers 12 and the like. This solves the conventional problem of noise caused by each blower 12 and the like.

Furthermore, each blower 12 and each auxiliary blower 14
are protected from rain, dew, etc. by the air tent 11, so each blower 12 etc. will not rust or be directly exposed to dust, etc., thereby preventing damage to each blower 12 and each auxiliary blower 14. You can press it as hard as you can.

Furthermore, since the house 10 according to the present invention can always form a steady flow of outside air near the plants P inside the house or the cage-like pedestal 18, the growth and fruit set rate of the plants P can be improved. Alternatively, drying can be performed well.

(Summary) As detailed above, in the present invention, as exemplified in the above embodiment, "a house is formed by airtightly enclosing the entire area where plants are planted or where drying materials are placed." a blower 12 and an auxiliary blower 14, each of which has an air suction duct connected to an opening formed in the air tent 11 and is entirely disposed at the lower part of the air tent 11; It has a heating device 12c that selectively heats the outside air taken in from the suction duct, and an exhaust port 13 that is provided in the air tent 11 and discharges excess outside air from each blower 12 and the auxiliary blower 14. 13 and the entrance/exit 15 are arranged on the opposite side of the blower 12, and the auxiliary blower 14 is placed on the side opposite to the blower 12.
It is characterized by the fact that the air blower 12 and the auxiliary blower 14 are placed between the air outlet 13 and the air outlet 13, and the air ducts of the blower 12 and the auxiliary air blower 14 are directed toward the outlet 13. This makes the structure and installation work extremely simple. It is possible to provide an air tent house that can solve the aforementioned problems of dead space, damage caused by rain, noise generation, etc., and also allows plants to grow well.
