Patent number: 11668509Abstract: Left and right edge portions of an external casing of a container refrigeration apparatus each include a column member that is continuous from the upper end to the lower end of a casing. Left and right edge portions of an internal casing each include a side plate that is continuous from the upper end to the lower end of the casing. The column members of the external casing and the associated side plates of the internal casing are fixed together, thereby increasing the strength of the casing including the external casing and the internal casing.Type: GrantFiled: March 4, 2022Date of Patent: June 6, 2023Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Yuuya Hirama, Makoto Ikemiya, Kazuyasu Matsui

Patent number: 11647761Abstract: A space which is present between an air intake surface (90a) provided with an air intake port and an air filter (76) is regarded as a primary space (P) through which air flows into the air filter (76), and a plurality of spaces, each of which is present between one of other surfaces of the air filter (76) and a filter box (90), are regarded as secondary spaces (Q) into each of which the air flows out from the air filter (76), so that the air is taken out from side surfaces and an upper surface of a filter unit (75). This configuration reduces the increase in size of the filter unit (75) of a gas supply device (30) even if a dust holding capacity of the filter is made larger than before.Type: GrantFiled: July 20, 2018Date of Patent: May 16, 2023Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Hirotaka Tagawa, Kazuyasu Matsui, Makoto Ikemiya

Patent number: 10955146Abstract: A fan includes a core part, a vanes, a ring part and a flow rectifying member. The ring part includes first second and third parts. The first part includes a first end overlapping with a flow rectifying member end and extends axially on a radially inner side of the flow rectifying member. The second part includes a second end spaced from the flow rectifying member end, overlapping with the flow rectifying member, and connected to the first end. The third part is connected to the second end, and extends on the radially outer side of the flow rectifying member end. The second end overlaps with a virtual point reached by the flow rectifying member end being linearly extended toward an upstream side. A first dimension, a radial length of the third part, is at least 0.5 times a first straight-line distance between the flow rectifying member end and the virtual point.Type: GrantFiled: December 8, 2017Date of Patent: March 23, 2021Assignee: Daikin Industries, Ltd.Inventors: Kento Shibuya, Tsunehisa Sanagi, Kouji Somahara, Kazuyasu Matsui
