The present invention relates to a stirring fan, such as single head or multi head farming mainly installed inside and outside the house (including greenhouses, barns, temporary buildings, etc.).

Background Art Conventionally, a stirring fan for a house or the like has a structure in which a fan and a fan card are provided in a stirring fan main body (frame). The method of using a stirring fan, such as for the house, may be installed in, for example, a copper direction or a direction orthogonal to the copper using a girder-constituting pipe or a supporting member of the house, and the like (principle in principle). In the same direction) to blow wind (hot, cold, etc.) as far as possible. In addition, a configuration is employed in which the wind is blown in a substantially horizontal direction, and the expansion of the reach of the wind and / or the expansion of the blowing range (blowing area) are adopted.

However, in the structure of the conventional stirring fan, various studies have been conducted from the fact that the expansion of the wind reach distance and / or the expansion of the blowing range (which is referred to as the "reach distance and / or blowing range") is not sufficient. .

In view of the above, an example of a document relating to the wind reach and the like, which is the object of the present invention, will be described. Document (1) is an electric blower of Japanese Patent Laid-Open No. 10-37896. Its contents include an air guide provided in the casing disposed on the outer periphery of the casing, a wing constituting a plurality of guide flow paths facing the outer periphery of the impeller, a conveying guide flow path connected to the guide flow path, and conveying The conveyance guide vane is installed in the guide flow path, and the curved portion is formed on the bracket facing the conveying guide vane, and the curved size of the curved portion is set between the minimum size between the adjacent wings and the height of the conveying guide blade, and the groove is provided on the outer periphery of the casing holding part of the bracket. It is a configuration formed. The characteristic is to ensure the turbulence prevention of air and the maintenance of the casing.

There is also a circulation ventilation system in the house, using a stirring fan (circulation fan) conventionally and / or disclosed in Japanese Patent Application Laid-open No. Hei 10-37896. It is a so-called adiabatic circulation ventilation system. The adiabatic circulation ventilation system has a structure in which a stirring fan is installed in an adiabatic manner.

Since Japanese Unexamined Patent Publication No. 10-37896 has a configuration in which vortex vanes (wings or conveying guide vanes) are respectively provided in the guide flow path on the intake side and the conveyance guide flow path on the discharge side, even if it is possible to correct the flow of wind. It cannot be said that it is a sufficient structure / structure for the expansion of the reach distance which this invention intends. Moreover, although the structure which installed the hood (cylindrical) in the stirring pan for the purpose of extending the reach of wind is disclosed in the literature which is not disclosed etc., in the cylinder of a simple structure, it reaches | attains like Japanese Unexamined-Japanese-Patent No. 10-37896. It cannot be said that it is sufficient structure for distance expansion.

In addition, in the conventional heat-insulated circulation ventilation system, it is necessary to study, and to accurately select and attach an installation place to blow the wind almost uniformly and every corner of the house. Therefore, it is desired to further increase the reach distance in the house, to further improve the heating effect, to eliminate or control pests, while facilitating attachment of the stirring fan and facilitating management. As one of the structures according to the said request, a multihead type circulation ventilation system is mentioned, for example.

The present invention promotes the expansion of the reach using a multi-head stirring fan (multi-head pan), and sends wind to the boundary layer to promote photosynthesis, thereby preventing disease and promoting growth, stagnation of air, and excessive temperature rise. It aims to prevent disease, prevent painting, improve growth, prevent high temperature in summer, increase heating effect in winter, circulate smoke and carbon dioxide, and equalize effects. An object of the present invention is to provide a stirring fan such as farming, which is optimal for achieving the above object and can be provided for practical use.

The present invention is a multi-head agricultural stirring fan having a structure in which a plurality of stirring fans described in the claims are provided on the support, so that the air in the house can be used in a circulation ventilation system.

When an example of embodiment of this invention was described, the characteristic of the single head type | mold stirring pan and the two head type | mold (a type of multiple head type) stirring fan was demonstrated in FIG. The stirring fan in the said example was a tapered cylindrical body and stator of 340-φ370, and the difference of the wind reach became clear. This is particularly noticeable in wind flows from 10m to 50m. The expansion of the reach can be expected the effect of the above-described polynomial stirring fan. One example of the above expectations is that each of the above-described effects is exerted by sending a gentle wind to the crops by suppressing the spread of the wind so that the leaves of the crops are not smeared or damaged by the wind.

In addition, since the synergistic effect by the stator blades and the axial flow fan can be exerted, for example, it is possible to smoothly induce wind (ejection wind or jet wind) from the strong wind region of the stirring fan outer periphery toward the weak wind region near the center of the stator blade. It is possible to achieve uniformity of the wind (discharge wind) discharged from the stirring fan, to increase the reach of the discharge wind, or to suppress the spread of the discharge wind, thereby preventing the wind at the obstacle in the installation place. There are characteristics such as being able to suppress the reduction of the reach distance (wind loss and diffusion) generated by the touch. In addition, there is an advantage that the gap between the obstacles can be used at least sufficiently (the spread of the wind due to the obstacles is small) compared to the fan without the wing body. The stirring fan is advantageous in that it can be used in a system (ventilating system) that sends air to crops in the house. In addition, the stirring fan can be used for heating and heating measures of the house, thereby expanding the harvest, improving the growth, preventing the disease, reducing the like, and the like.
