Patent number: 11774114Abstract: An air treatment device includes: a casing having an inlet through which air is drawn, and an outlet out of which the air drawn through the inlet is blown; a blade configured to adjust a direction of the air blown out of the outlet; and a generator configured to generate an antimicrobial element that sanitizes the blade. The blade has a first surface, and a second surface opposite to the first surface. The blade is shiftable between a first position in which the antimicrobial element is provided to the first surface and a second position in which the antimicrobial element is provided to the second surface.Type: GrantFiled: July 25, 2022Date of Patent: October 3, 2023Assignee: Daikin Industries, Ltd.Inventors: Hidekazu Tanaka, Ryuuji Akiyama, Kei Suzumura

Patent number: 11384957Abstract: A drain pan includes a light-transmissive member forming at least part of the drain pan and is for transmitting ultraviolet light emitted from a light source. The light-transmissive member has a light-emitting surface that is exposed to the inside of the drain pan and from which ultraviolet light that has been transmitted through the light-transmissive member is emitted.Type: GrantFiled: July 15, 2021Date of Patent: July 12, 2022Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Ryuuji Akiyama, Kei Suzumura

Patent number: 11318478Abstract: A shaft member has the same polarity as discharge electrodes. Each of the discharge electrodes has an electrode body and a tip end which is formed at an end of the electrode body facing an inner peripheral surface of a counter electrode. The discharge electrodes extend such that the tip ends and the electrode bodies are misaligned with each other in an axial direction of the shaft body. A streamer discharge travels from the tip ends of the discharge electrodes toward the inner peripheral surface of the counter electrode.Type: GrantFiled: August 4, 2017Date of Patent: May 3, 2022Assignee: Daikin Industries, Ltd.Inventors: Kiyoshi Kuroi, Kei Suzumura

Publication number: 20210088238Abstract: A dust removal device blows air toward a subject and removes dust. The dust removal device includes a fan arranged to blow air, and a blow-out location changing part arranged to change a blow-out location of air that is blown by the fan and to move toward the subject. The blow-out location changing part is arranged to change the blow-out location in accordance with a height of the subject such that the air is blown toward the subject from a neck down.Type: ApplicationFiled: December 4, 2020Publication date: March 25, 2021Inventors: Kei Suzumura, Tomohiro Yabu

Publication number: 20200148561Abstract: In a water passage, a first inflow-side insulator, a second inflow-side insulator, and an electric-discharge water tank are each formed like a sealed container. A tap water pipe is connected to the electric-discharge water tank via inflow-side insulators, and the electric-discharge water tank is connected to water supply headers. The water passage has a hermetic structure that is open to the atmosphere only at a supply opening of each of the water supply headers. Therefore, when pressurized tap water is supplied to the water passage, water flows through the water passage. As a result, restrictions on the positional relationship between a supply target of treated water and a water treatment device are reduced, and the usability of the water treatment device is improved.Type: ApplicationFiled: March 13, 2018Publication date: May 14, 2020Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Tsunahiro OHDOU, Masaya NISHIMURA, Kei SUZUMURA

Patent number: 10581227Abstract: A discharge unit includes a discharge electrode, a counter electrode opposed to the discharge electrode, and an insulation member having a surface. The surface is continuous from the discharge electrode to the counter electrode. A wall portion is provided on one side with respect to a discharge region formed by the discharge electrode. The wall portion is configured to suppress a contaminant from adhering to the surface of the insulation member.Type: GrantFiled: December 24, 2015Date of Patent: March 3, 2020Assignee: Daikin Industries, Ltd.Inventors: Shunji Haruna, Tatsumi Enokida, Kei Suzumura, Kiyoshi Kuroi, Toshio Tanaka

Patent number: 9468937Abstract: An air purification device includes a controller configured to perform a normal discharge operation in which a discharger generates streamer discharge to purify air, and an emergency discharge operation in which, in order to remove substances, which are components contained in air, adhering to electrodes of the discharger due to the normal discharge operation, a higher voltage than that in the normal discharge operation is applied to the electrodes to cause the discharger to generate spark discharge. The controller adjusts an application voltage such that a current value between the electrodes is maintained constant, and the upper limit V of the application voltage is set at a value greater than an inter-electrode distance of d×1.2 (V?d×1.2).Type: GrantFiled: August 6, 2013Date of Patent: October 18, 2016Assignee: Daikin Industries, Ltd.Inventors: Toshio Tanaka, Kenkichi Kagawa, Shunji Haruna, Tatsumi Enokida, Kei Suzumura
