Air blowing fan, circulator, micro-particle diffusion device, and air circulation method

Abstract

A circulator (1) which is mounted on a side wall (S) in a room or on a ceiling wall (T) located close to the side wall (S) in a room and which circulates air present in the room. The circulator (1) comprises, in order from a first wall surface (P1) adjacent to the side wall (S) in the horizontal direction, a first outlet (4a), a second outlet (4b), and a third outlet (4c) which are disposed next to each other in the horizontal direction. A first air flow (A1) which flows along the ceiling wall (T) and descends along the first wall surface (P1) is delivered from the first outlet (4a), a second air flow (A2) which flows along the ceiling wall (T) and descends along a second wall surface (P2) facing the side wall (S) is delivered from the second outlet (4b), and a third air flow (A3) which flows along the ceiling wall (T) and descends along a third wall surface (P3) facing the first wall surface (P1) is delivered from the third outlet (4c)

Description

technical field [0001] The invention relates to a fan for sending out airflow. Furthermore, the present invention relates to a circulator and an air circulation method for circulating indoor air. Furthermore, the present invention relates to a particle diffusion device for sending out particles such as ions and diffusing them into a chamber. Background technique [0002] Patent Document 1 discloses a conventional circulator. The circulator is installed on the indoor floor, has a suction port on the lower part, and has a blowing port on the upper surface. Driven by the fan installed inside the circulator, the air in the room is sucked in from the suction port along the floor, and the air is sent forward and upward from the blower port. Thereby, indoor air can be circulated. [0003] In addition, Patent Document 2 discloses a conventional particle diffusion device. The microparticle diffuser is arranged on the top surface of the refrigerator or the like, and a fan is inst...

Problems solved by technology

But in this case, since the air flow is also sharply turned on the exhaust side of the fan, the air supply efficiency becomes poor and the noise becomes louder

[0020] In addition, the same problem exists in the particle diffusion device that sends particles into the room and diffuses the particles. In this particle diffusion device, a particle generating device is installed in the air flow passage of the circulator, and the particle generating device generates ions, fragrances, deodorants, etc. , insecticides, fungicides and other particles
