BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concentrated fan (collectively referred to as a farm fan, a livestock fan, a steam drying fan, a factory fan, etc.), such as a prefabricated, decomposable ventilation fan, blower fan, or stirring fan, installed on a wall or in a building.

Conventionally, this type of concentrated fan (ventilation fan) is a structure assembled at a factory, and this assembled ventilation fan is shipped and / or conveyed by conveyance means, such as a truck. Therefore, it can be said that rationality is inferior, such as a volume becomes large at the time of conveyance, and it requires a limited number, or assembly cost and packing cost, complexity of work, an increase of cost, and a large installation area are required at the time of conveyance.

The ventilation fan is composed of a rim (casing) of a bell mouse, a drum, etc., an impeller rotating by a driving part (motor), and a guard installed as necessary, with a slight gap on the inner circumferential side (inner side) of the rim. It is an integrated structure that installs the tip of the impeller. Therefore, the following problems are mentioned. A) In forming the edges, a large press machine, a mold, etc. are required, which necessitates complicated work, increased cost, and a large factory space. B) High precision and skill are required in forming and assembling as it is designed to install the distal end of the impeller with a slight gap on the inner circumferential side of the rim. And assembly at the installation place becomes difficult. C) In the structure in which the frame and the support are formed of pipes, the pipe diameter and the pipe diameter of the house material (the diameter of the frame of the frame assembly of the house) are separate structures, and commonity with the pipe fixing member and other parts is not achieved. . D) When lowering the ventilation fan with a hoist, such as a rope (in principle, the lifting operation is also the same, the following description is referred to as lowering), and a fastening bracket is required, and a component of the ventilation fan is required. Damages the rope by the edges. Moreover, since it becomes difficult to secure the standing state of the ventilation fan, labor is required when hanging the rope, and experience is required. E) The installation of the ventilation fan is standardized. Therefore, it can become difficult in the wiring after installation, the change of installation direction, etc. F) Since the inflow of air into the impeller or the air outflow from the impeller is suppressed by the rim, free flow is restricted, and loss, pressure loss, etc. may occur in terms of noise generation, suction, blowing, and the like.

In view of the above circumstances, the following structure has recently been proposed as a lightweight and thin ventilation fan (improved ventilation fan). The outline thereof is composed of an annular pipe main body, an impeller support plate provided in a radial direction from an axis of the pipe frame, and a drive unit provided at a central position of the support plate. Therefore, considerable achievement can be expected in solving the above a) and b). However, it can be said that there is room for improvement in terms of b), c), d) or e).

Moreover, the prior art document of this invention is the agricultural ventilation fan of Unexamined-Japanese-Patent No. 3-100733. This design is a prefabricated and disassembled ventilation fan, and its structure is integrated by assembling the fan and driving motor on the fan frame, and by integrating the shutter blades on the shutter frame. It is a composition that unites a border. Therefore, it is not a structure which assembles and disassembles the frame body (ventilation fan frame body) and an impeller which this invention intends.

(2) By removing the conventional rim from the ventilation fan, air can be introduced into the impeller from the impeller outer periphery, thereby increasing the amount of air.

(3) By eliminating the conventional edging from the ventilation fan, there is no structure which suppresses the inflow of air into the impeller or the ejection of air from the impeller. Also, the air flows freely, resulting in less noise and the flow of air. , Wind speed, pressure loss, etc. can be eliminated.

5. Features (additional functions, etc.) by specific use,

(1) In the structure formed by the pipe, a fluid can be supplied by providing the injection holes (outlets), such as holes and nozzles, in the whole or part of the pipe such as the rim and the support, and the ventilation fan is a sprayer (spray fan). Take advantage.

(2) In the structure formed with a pipe, the ventilation fan is used as a hot air fan (heater) by using the inside of the frame and the support in the insertion space of the sheath heater, and inserting the sheath heater therein. The heat source of this sheath heater is selected suitably.
