Patent number: 10295207Abstract: An air blowing device adapted to be used in such a manner that at least two of the devices are horizontally and/or vertically aligned with each other, thereby to obtain a uniform flow of air in the downstream direction from device to device. An air-permeable front surface (11f) is formed to the blowing device (1) at the downstream side of a rectifier mechanism, and side surface sections (11a) which extend in the upstream direction of the device (1) are formed at both edges of the air-permeable front surface (11f). First ventilation holes (70a) are distributed at the air-permeable front surface (11f), and second ventilation holes (70b) are distributed at the side surface sections (11a).Type: GrantFiled: March 29, 2017Date of Patent: May 21, 2019Assignee: Koken Ltd.Inventors: Kazuma Fukiura, Tomoyuki Kakinuma, Taketo Suzuki, Takahiro Sato

Patent number: 10197302Abstract: A local air cleaning apparatus (1) is provided with a push hood (2) having an air flow opening face (23) for blowing out a cleaned uniform air flow and a guide (3) provided on a side of the push hood (2) having the air flow opening face (23), the guide (3) extending from the side thereof having the air flow opening face (23) toward a downstream side of the uniform air flow to form an opening face (31) at a downstream end portion thereof. The push hood (2) is arranged such that the uniform air flow blown out from the air flow opening face (23) passes through the inside of the guide (3) and then collides with an air collision face (W) on a downstream side of the opening face (31). The opening face (31) of the guide (3) is spaced apart from and opposed to the air collision face (W) to form an open region between the opening face (3) and the air collision face (W).Type: GrantFiled: June 22, 2012Date of Patent: February 5, 2019Assignee: Koken Ltd.Inventors: Taketo Suzuki, Tomoyuki Kakinuma, Kozo Nitta, Yuki Fujishiro, Kazuma Fukiura, Takahiro Sato

Patent number: 10161645Abstract: A local air cleaning apparatus (1) is provided with push hoods (2, 3) having an air flow opening face (23) for blowing out a cleaned uniform air flow and a pair of guides (4, 5) provided on sides of the push hoods (2, 3) having the air flow opening faces (23), the guides (4, 5) extending from the sides thereof having the air flow opening faces (23) toward downstream sides of the uniform air flows to form opening faces (41, 51) at downstream-side end portions of the guides. The push hoods (2, 3) are arranged such that the respective air flow opening faces (23) are opposed to each other. The opening faces (41, 51) of the guides (4, 5), are spaced apart from and opposed to each other to form an open region between the opening faces (41, 51) of the respective guides (4, 5).Type: GrantFiled: June 22, 2012Date of Patent: December 25, 2018Assignee: Koken Ltd.Inventors: Taketo Suzuki, Tomoyuki Kakinuma, Kozo Nitta, Yuki Fujishiro, Kazuma Fukiura, Takahiro Sato
