Description

  The present invention relates to a ventilation system for a house (a house such as a vinyl house or a glass house) in which fruit vegetables, root vegetables, and other vegetables are cultivated.

  The ventilation and / or ventilation system (house ventilation) in the house is a healthy growth environment, expansion of the harvest and / or improvement of the quality in the growth of the crop, and also the efficient and simple of the crop desired by each person. This is the minimum requirement for safe cultivation. Also, the air blowing in the house is an operation that requires extremely fine work because the air blowing amount, the air blowing time, etc. must be appropriately changed according to the crop pattern.

  In recent years, what has been particularly demanded is that the insect net is stretched in the longitudinal direction of the house and / or in the direction of the wife surface in the ventilation (air flow) in the house, so that it is substantially horizontal in the longitudinal direction of the house. For example, a house by securing an air flow in a direction and wide-area air flow, expanding the land area in the house, and improving the efficiency of workability as desired by each person Expansion of the air blowing area to the crops in the plant, ensuring efficient air blowing, lowering the air blowing amount, achieving economic effects and / or resource savings by lowering the fan and / or ventilation fan capacity, etc. It is to reduce the running cost, increase the crop yield by expanding the area, and improve the workability of the crop.

  An example of the present invention will be described.

  1 is a bird's-eye view of the whole house provided with a ventilation fan and a fan, FIG. 2 is a side view of the whole house shown in FIG. 1, FIG. 3 is a front view of the main part of the house shown in FIG. FIG. 5 is a front view showing another example of a house in which a ventilation mechanism is provided with a rotation mechanism, and intake or exhaust is performed by this ventilation fan, and FIG. It is the front view which showed another example which wore.

  In the figure, a greenhouse 1 such as a single building, a multi-storey vinyl house, a glass house, etc. has a plurality of vertical frame bodies 10 erected with respect to the farm field G, and is perpendicular to the vertical frame bodies 10. Thus, the horizontal frame 11 is supported. On the horizontal frame body 11, the fan 4 and / or the ventilation fan 5 are placed at substantially the center of the horizontal frame body 11. A dome-shaped roof frame 12 is formed from both ends of the horizontal frame 11.

  The vertical frame body 10, the horizontal frame body 11, and the roof frame body 12 are incorporated at appropriate intervals in the longitudinal direction 1a and the end face direction 1b to form the house 1.

  The insect nets 2 and 2 are respectively stretched on both side surfaces 100 and 100 (referred to as 100) in the longitudinal direction 1a of the house 1, and the fan 4 (introducing fan) is formed on one end surface orthogonal to the longitudinal direction 1a. , A suction fan, a fan such as a forced suction fan) and / or a ventilator 5 on the other end face 101. In this example, the insect nets 2 and 2 (referred to as 2) are respectively stretched on the wife surfaces 101 and 101 on the one side and the other side of the house 1 at intervals of 7 and 7 (referred to as 7). . This stretch is designed to partition the house 1 in the longitudinal direction of the house and in the direction of the face, while ensuring a substantially horizontal air flow and a wide area air flow in the longitudinal direction of the house, It is set as the structure which aims at prevention of invasion and escape of a beneficial insect, and this structure achieves, for example, pesticide-free cultivation and / or effective use of beneficial insects and labor saving.

  And the opening part 3 is demonstrated below. The open portion 3 is provided with a space 7 in the longitudinal direction, and is suspended from the ceiling surface 1 c inside the wife surface 101 provided with the space 7 so as to surround the fan 4 and / or the ventilation fan 5 with the insect-proof net 2. Then, it is folded in the orthogonal direction toward the outside and is stretched up to the end face 101. When viewed from the side, the insect net 2 is L-shaped. Note that. The portion that is folded back in the orthogonal direction is parallel to the horizontal frame body 11, and the insect net 2 is easily stretched by attaching the insect net 2 to the horizontal frame body 11 and securing and / or supporting it. , Stable.

  Moreover, since this open part 3 is parallel to the horizontal frame 11, if the position of the horizontal frame 11 is changed, this open part 3 will also fluctuate. And it is thought that the change of this horizontal frame 11 can be changed to the height which an operator desires according to characteristics, such as the quality of the crop C, at the time of incorporating the house 1.

  Furthermore, since the opening part 3 has the same height as the horizontal frame body 11, that is, the height of the vertical 3 a, an operator enters and exits the house 1 at the entrance / exit 15 arranged at the lower end of the horizontal frame body 11. In the past, it was necessary to lift the insect net 2 when entering or exiting, or to make a cut so that the operator could pass through the insect net 2. This need is eliminated, and the risk of injury to the insect net 2 due to the operator getting caught or tripping is reduced, and it is considered that a comfortable crop can be produced for the operator.

  In the place where the insect net 2 is stretched, as described above, the flow of the substantially uniform wide-area and / or horizontal air of the outside air introduced through the fan 4 (on the introduction side and the exhaust side) is reduced. It is intended to ensure, or to ensure a substantially uniform horizontal introduction / exhaust method of outside air. This interval 7 is considered to contribute to substantially uniform introduction / exhaust of outside air, change of the blowing direction, and the like. These wind flows can be ensured on both the introduction side and the exhaust side, and the effectiveness is remarkable. In addition, the interval 7 has an actual advantage that it can be used for securing an installation space for the fan 4 and / or the ventilation fan 5 and facilitating management.

  In another embodiment, the insect net 2 has a structure in which two insect nets 200 are overlapped and a gap 8 is formed between the two overlaps, and the introduced outside air / air in the house 1 ( To avoid slowing down the inside air) and to secure the flow, to surely prevent the invasion of pests and prevent the escape of beneficial insects, or to facilitate the maintenance management, simplify the tension, etc. Is intended. The gap 8 is not necessarily required, and is determined in consideration of the scale of the house 1, cultivation conditions such as terrain, time, and crops, or the specifications of the fan 4 and / or the ventilation fan 5. Although not shown, the number of the insect net members 200 may be one to a plurality.

  In such a configuration, outside air is introduced substantially uniformly from the entire house 1 through the fan 4. Desirably, outside air is introduced through a fan 4 provided on one end face 101 of the house 1. If necessary, outside air is introduced from a part of the vicinity (side surface 100). That is, one or a plurality of insect repellent nets 2 are stretched inside the both wife surfaces 101 of the house 1, the outside air is introduced into the house 1 via the fan 4 and the one insect repellent net 2, and the other insect repellent net The inside air of the house 1 is exhausted through the fan 2 and the ventilation fan 5, and is substantially uniform in the longitudinal direction 1a of the house 1 through the fan 4 and the insect net 2 on one side and the insect net 2 and the ventilation fan 5 on the other side. While ensuring a substantially horizontal air flow A and a substantially uniform wide-area air flow B, it is possible to ensure a uniform growth environment in the house 1 and avoid physiological disorders. In addition, by introducing the outside air from the side surface 100, new outside air is introduced into the air flow A in the substantially horizontal direction and the wide air flow B. To ensure the flow of

  In addition, the fan 4 and / or the ventilation fan 5 are provided at the free end of the extended frame body 40, a space is secured, and the ventilation fan 5 is rotatably provided at the free end of the frame body 40. By using the interval, the ventilation fan 5 can be used as an intake ventilation fan and an exhaust ventilation fan, and the intake or exhaust can be used properly at the time desired by the operator. It is considered that diversification of ventilation such as wind direction and efficient ventilation can be performed.

  [1] The growth environment of the house 1 and / or the working environment in the house 1 can be maintained.

  [2] [I] Can be used to eliminate the rise in temperature in the house 1, [b] It is not limited to several hours after sunset after sunrise, which is a time zone that is safe from the thermal environment as in the past. In addition, it enables day and night work, can be used to achieve efficient farming work, [c] can be used to improve the work thermal environment, [d] can perform forced convection heat transfer, and [e] can reduce field area. By expanding, it is possible to increase the crop yield, and [e] it is easy for workers to enter and exit the house.

  [3] The insect net 2 is a problem that further reduces the air permeability of the house 1, but the present invention relates to the outside air introduced from the nets 2, 2 provided on the side surfaces 100, 100 of the house 1, The uniform substantially horizontal air flow A and the substantially uniform wide-area air flow B can generate, for example, trapped wind and clean up the air in the house 1, There are effects such as crop dying and prevention of burning.

  [4] By introducing the outside air by the wind, the inside of the house 1 is made positive pressure, the house 1 can be prevented from collapsing, and the fan 4 and the ventilation fan 5 can be reduced in energy saving and cost reduction.

  [5] Although not shown, an induction fan may be installed on the ceiling surface and space of the house 1 (it may be installed with a height difference) to accelerate and / or increase the total air flow AB. In this example, the following synergistic characteristics can be considered. Thus, there is practicality such that an external air introduction type forced ventilation system can be constructed or a high-temperature suppression system can be proposed.

[6] Temperature difference ventilation on the ceiling surface 1b of the house 1 (by a skylight, not shown) is promoted, the time during which the house 1 can be safely operated in terms of the thermal environment is lengthened, and the total air flow AB and ventilation Ensuring further combined ventilation and / or airflow;
[7] There are effects such as being able to construct a forced ventilation system of the outside air introduction type or having a practicality such as being able to propose a high temperature suppression system.

  [8] Desirably, the internal pressure of the house 1 can be increased to achieve wind resistance, earthquake resistance, and insect invasion prevention effects.

  [9] Cultivation of crops that are vulnerable to high temperatures is possible, which is useful.
