The present invention relates to a noiseless pressure blower that can be installed in a place where a lot of resistance is generated by a duct.

  In general, a blower increases the strength of the flow of wind using gas, particularly air, and is broadly classified into a turbo blower and a positive displacement blower. Among these, the turbo blower is divided into an axial blower that obtains energy by the lift of blades generated by the rotation of the rotating wheel, and a centrifugal blower that obtains energy by centrifugal force.

  Among such blowers, the centrifugal multiblade blower is provided with a suction port in the center of one side surface of the main body that is cylindrical as a whole, and an outflow port is formed on one side of the circumferential surface. It is formed by a blade that rotates about an axis centered on a cylinder, a scroll, an impeller, and the like. As a result, the blades, which are a small wing provided with a plurality of blades, are tilted and rotated to one side, and air is sucked into the center of a cylindrical impeller formed on a large number of blades and blown outward. is there.

  Such a blower is used by being installed in a factory, an indoor work place, a basement, a dining room, a kitchen or the like that requires ventilation. Since such a blower rotates at a high speed, not only noise is generated due to friction of air, but when using a duct, not only idling occurs due to the resistance of the duct and power is lost, There is a problem that noise is generated by eddy currents and ventilation is not good.

  Accordingly, the present invention was created to solve the above-described problems, and the object of the present invention is to minimize the friction of air to prevent the generation of noise and to generate resistance by a duct or the like. Another object of the present invention is to provide a noiseless pressurized air blower that can reliably transfer air to a place where it is to be performed.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, and like reference numerals denote like parts throughout the drawings.

  FIG. 1 is a perspective view of a noiseless pressure blower according to an embodiment of the present invention. FIGS. 2 and 3 are a plan view and a cross-sectional view of the blower shown in FIG. FIG. 4 is an exploded perspective view of main parts of the blower.

  As shown in the figure, the noiseless pressure blower according to the present invention indicated by the reference numeral 1 includes a main body 10, a pressure mechanism 20, a control mechanism 30, and the like.

  As shown in FIG. 3, the main body 10 has a shape in which three cylinders 13 communicate with the side surfaces, and an inlet port 11 and an exhaust port 12 are formed on the two communicating side surfaces located on the outer side. . The case 5 is attached to the outside of the main body 10.

  The control mechanism 30 is mounted on the cylinder 13 located at the center of the main body 10, and the pressurizing mechanism 20 is mounted on the two cylinders 13 positioned on the side surfaces.

  As shown in FIGS. 2 and 3, the rotational force driven by the motor 40 drives the pressurizing mechanism 20 and the control mechanism 30 through a gear 50, respectively. The rotation directions of the pressure mechanism 20 rotate in opposite directions, and the rotation speeds maintain the same rotation speed.

  The suction port 11 and the exhaust port 12 formed in the main body 10 are respectively formed in a cylinder 13 on which the pressurizing mechanism 20 is seated. As shown in FIG. Since it has a sawtooth shape, it is possible to reduce the noise generated at the initial stage of sucking air.

  Further, as illustrated, the pair of suction ports 11 and the pair of exhaust ports 12 are positioned in opposite directions. Thus, the suction port 11 and the exhaust port 12 positioned at different positions cannot suck air in the same direction and discharge air in the same direction. Accordingly, the suction port 11 and the exhaust port 12 provided in opposite directions are connected to each other by the communication port 70, and the communication port 70 is provided between the main body 10 and the case 5 as shown in FIG. Located in. Since the suction port 11 and the exhaust port 12 are connected to each other by the communication port 70, air on one side can be blown to the other side.

As shown in FIG. 5, the control body 33 has a spiral shape, in which a hollow portion is formed and has a constant volume.

  The pressure mechanism 20 and the control mechanism 30 rotate at the same rotational speed, but the pressure plate 23 and the control body 33 rotate with each other while making line contact in the longitudinal direction. Therefore, since the control body 33 and the pressure plate 23 always rotate in contact with each other, there is no space between the pressure plate 23 and the control body 33, and the air flow is blocked.

  The operation of the above-described configuration of the present invention will be described with reference to FIG.

  As shown in the figure, the pressurizing mechanism 20 and the control mechanism 30 that rotate at the same speed in opposite directions rotate while being in line contact with each other, and therefore, between the pressurizing mechanism 20 and the control mechanism 30. Air is blocked from moving.

  Accordingly, air is sucked into the suction port 11 by the rotating pressurizing mechanism 20, and the sucked air moves along the pressurizing plate 23 and is discharged through the exhaust port 12 located on the opposite side. become able to.

  As shown in the figure, since the pair of suction ports 11 and the exhaust ports 12 are positioned opposite to each other, the pair of suction ports 11 and the pair of exhaust ports 12 communicate with each other through the communication ports 70. As a result, air can be sucked on one side and discharged on the other side. (See Figure 1)
