Abstract

A conventional blower system for a house provided with fans and / or ventilation fans on both sides orthogonal to the longitudinal direction is intended to maintain the environment of the house by introducing outside air and exhausting the inside air based on this. However, since the structure does not include an insect net, the flow of the air in the house is not necessarily considered to be sufficient.
[Constitution] Fans and / or ventilation fans are installed on both sides of the house, and one or more insect nets are installed inside the both sides of the house. Introduce and exhaust the inside air of the house through the other insect-proof net / ventilation fan, and let the air in the horizontal direction in the longitudinal direction of the house pass through the fan / insect-net on the one side and the other insect-proof net / ventilation fan. It is a house blower system that secures the flow and wide-area air flow.

FIG. 4 is an enlarged perspective view showing an example of the insect-proof net, and FIG. 5 is an enlarged perspective view showing an example of the mesh of the insect-proof net.

  In the drawing, 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 a house 1 such as a single building or a continuous building, and a wife on one side orthogonal to the longitudinal direction 1a. The fan 4 (fans such as an introduction fan, a suction fan, and a forced suction fan) is provided on the face 101 and / or the ventilation fan 5 is provided on the other face face 101. In this example, insect nets 8 and 8 (referred to as 8) are respectively stretched on the wife surfaces 101 and 101 on one side and the other side of the house 1 at intervals of 7 and 7 (referred to as 7). . This upholstery is sealed and cut off so as to partition the house 1, and is configured to prevent the invasion of harmful insects and the escape of beneficial insects. With this configuration, for example, pesticide-free cultivation and / or effective use of beneficial insects And achieve labor saving. And this space | interval 7 ensures the substantially uniform wide area and / or horizontal airflow of the external air introduce | transduced via the fan 4 (in the introduction side and exhaust side) (refer FIG. 2), or external air It is intended to ensure a substantially uniform horizontal introduction / exhaust method (see FIG. 1). 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.

  Further, the insect net 8 has a configuration in which two insect nets 800 are overlapped and a gap 10 is formed between the two overlaps, so that the introduction of the introduced outside air and the air in the house 1 (inside air) is avoided. In addition, it is intended to ensure the flow, to surely prevent the invasion of pests and prevent the escape of beneficial insects, or to facilitate the maintenance management and the simplification of the tension. The gap 10 is not necessarily required, and is determined in consideration of the scale of the house 1, cultivation conditions such as topography, 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 800 may be one to a plurality.

  The insect net 8 is connected to the fan 4 and / or the ventilation fan 5, that is, in the longitudinal direction 1a of the house 1, a substantially uniform air flow A in the substantially horizontal direction and a substantially uniform wide area air flow. In order to secure the flow B, the mesh of the upper insect net 8a may be larger than the mesh of the lower insect net 8b.

  In the figure, 11 indicates the entrance / exit of the house 1.

  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 8 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 8, and the other insect repellent net The inside air of the house 1 is exhausted through the fan 8 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 8 on one side and the insect net 8 and the ventilation fan 5 on the other side.

In addition, by introducing 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, so that the entire area of the house 1 is comprehensive. Can be secured.

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

  [2] The conventional problem, that is, the work intensity of farm work in institutional cultivation is mainly from extremely light work to light work with RMR (energy metabolism rate) of 1-2. In a house covered with a high-temperature net, WBGT (wet bulb temperature) rises rapidly from the operator's chest to the vicinity of the face as the solar radiation increases. While it is higher than the covered house, it is effective in solving problems related to the thermal environment of the house.

  [3] [b] Can be used to eliminate the rise in temperature in the house 1, [b] Not limited to just a few hours after sunrise, which is a time zone that is safer in terms of thermal environment as in the past. In addition, it is possible to work day and night, and can be used to achieve efficient farming work, [c] can also be used to improve the work thermal environment, and [d] can achieve forced convection heat transfer. .

[4] By extending the net 2 to the floor surface of the house 1 or the vicinity of the foundation, it is possible to prevent infestation of pests and / or pests (including moles, rabbits, and insects) that fly. For example, it is possible to prevent intrusion into the house 1 from the side surface 100 and / or the opening of the ventilation fan 5 such as aphids, whiteflies and thrips (see FIG. 3).
[5] Although the net 2 is a problem that lowers the air permeability of the house 1, the present invention relates to outside air introduced from the nets 2, 2 provided on the side surfaces 100, 100 of the house 1, and substantially uniform in the house 1. For example, the air flow A in a substantially horizontal direction and the air flow B in a substantially uniform wide area can generate, for example, trapped winds and clean up the air in the house 1, There are effects such as prevention of withering and burning.

  [6] 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.

  Although not shown, an induction fan may be installed on the ceiling surface 1b and the space 1c of the house 1 (it may be installed with a difference in elevation) 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.

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

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

  “10” Cultivation of crops that are vulnerable to high temperatures is possible, which is useful.
