Abstract

<P>PROBLEM TO BE SOLVED: To provide a dust collector capable of avoiding the formation of a space where dust does not move by force with which the dust tries to move with airflow and gravity canceling each other, and efficiently recovering the dust, in the configuration of collecting the dust by the airflow in the dust collector. <P>SOLUTION: The dust collector is provided with a plurality of fan devices 7 arranged in a room and generating a dust collecting airflow 12 in the entire room by changing the direction and volume of the airflow in a manner associated with each other, and a dust collecting section 8 provided near a floor surface in the room and collecting dust moving with the dust collecting airflow 12. Since the dust collecting airflow 12 is generated as a swirl flow having a rotation axis substantially perpendicular to the floor surface, force with which the dust tries to move with the dust collecting airflow 12 and force with which the dust tries to move downward by gravity do not cancel each other and, as a result, the dust can more easily move with the airflow, enabling easier collection of the dust. <P>COPYRIGHT: (C)2010,JPO&INPIT

  However, in the above-described conventional configuration, the dust collection airflow is a swirling flow having a rotation axis in a substantially horizontal direction in the room, and an upward flow is generated depending on the position in the room. In a place where the airflow is directed upward, the force that the dust tries to move downward due to gravity and the force that the dust tries to move on the swirl flow cancel each other, and there is a problem that the dust becomes difficult to move.

A central air flow toward the center of the swirl flow is generated along with the swirl flow, and this air flow also flows upward depending on the position of the room. Therefore, the central airflow also has a problem that a place where the dust is difficult to move due to the force that the dust moves downward due to gravity and the force that the dust moves on the central airflow cancels each other.

In addition, since the central air flow toward the center of the swirl flow generated along with the swirl flow is also a flow directed in the horizontal direction, the force of dust moving downward due to gravity and the force of moving on the central air flow are canceled out. I'm afraid. Therefore, dust becomes easier to move.

  The dust collector of the present invention generates a swirling flow having a rotation axis in a substantially vertical direction with respect to the floor surface in the entire room, so that the force applied to the dust and the force to move on the air current does not cancel each other. Therefore, it becomes easy for the dust to move on the air current, and can be collected more efficiently.

Is configured to blow air toward the dust collection part, so that the rotating shaft of the swirl flow is formed at a position close to the dust collection part, and it moves on the swirl flow and efficiently moves the dust to the dust collection part. Can do. Also, dust can be efficiently collected in the dust collecting section by the drawing airflow drawn toward the center of the swirling flow generated near the floor surface with the swirling flow.

  In particular, the third aspect of the invention includes the dust collector of the first or second aspect of the invention, including an intake device that performs intake from the outside and an exhaust device that performs exhaust to the outside, and the intake portion is integrated with the blower. By configuring the exhaust part integrally with the dust collecting part, it is possible to ventilate the room without affecting the dust collecting air flow generated by the blower.

  In the fourth invention, in particular, the blower device according to any one of the first to third inventions is configured to operate in cooperation with an air conditioner in a room and generate a dust collecting airflow, thereby reducing the number of blower devices. A dust-collecting airflow can be generated and the air-conditioning equipment does not disturb the dust-collecting airflow.

5th invention is the air blower of any one of 1st-4th invention especially, The air blower arrange | positioned in the location most distant from the dust collection part among several air blowers is another air blower. The air flow is the same and the air is blown at a slow wind speed, and the rotational axis of the swirling flow on the floor surface is located close to the dust collecting part, so the balance of the swirling flow is lost and the swirling flow The rotating shaft is formed at a position close to the dust collecting portion, and dust can be efficiently collected into the dust collecting portion.

  In the sixth invention, in particular, the air blower according to any one of the first to fifth inventions is configured to blow air so as to generate a plurality of swirling flows in the room. Dust collection can be performed even when it is difficult to collect dust with a single swirling flow that swirls the entire room, such as when the two are substantially separated.
