Patent number: 10035717Abstract: To provide a voltage-type device for killing microorganisms in which a microorganism killing effect is high and scale is less likely to clog up through holes in electrodes. The device for killing microorganisms includes: a main body which a liquid to be treated flows in at one end and flows out at the other end; opposed electrodes that are arranged in the main body in parallel with a flow of the liquid to be treated and have mutually-opposed through holes; and a voltage source of which an anode is connected to one of the opposed electrodes and a cathode is connected to the other of them. When a straightened liquid to be treated is passed through the device for killing microorganisms, a stirring action is produced between the opposed electrodes, whereby hypochlorous acid can be diffused throughout the entire device and a high killing effect can be obtained.Type: GrantFiled: October 23, 2014Date of Patent: July 31, 2018Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Hiroshi Yamamoto, Akiyoshi Edagawa, Masafumi Sasai, Takuya Kotanagi, Hirohumi Minami, Hideki Nagaoka, Masafumi Nishimoto, Takashi Sakakibara
