Publication number: 20220397921Abstract: Provided is a hot and cold water mixer capable of performing stable temperature control, including a cold water supply pipe, a hot water supply pipe, a mixing pipe, flow rate adjustment valves, temperature sensors, flow rate sensors, a setting unit, and a control unit. When the control unit determines that either one of the flow rate adjustment valves cannot increase the flow rate, and also determines, by comparing the target flow rate for the one flow rate adjustment valve with the flow rate of water flowing through the one flow rate adjustment valve, that the target flow rate for the one flow rate adjustment valve is higher, the control unit calculates and updates the target flow rate for the other flow rate adjustment valve and controls the other flow rate adjustment valve based on the updated target flow rate.Type: ApplicationFiled: June 4, 2020Publication date: December 15, 2022Applicant: LIXIL CorporationInventors: Takayuki MIZUNO, Kenji OZEKI, Azumi KAMATA, Masaaki NAGATA

Publication number: 20220023464Abstract: An ultraviolet irradiator irradiates eyewear with an ultraviolet ray. The ultraviolet irradiator includes a base stored in an eyewear case that accommodates the eyewear, an irradiation element fixed to the base and irradiating the eyewear accommodated in the eyewear case with the ultraviolet ray, and a switch for turning on the irradiation element. The base is attachable to and detachable from the eyewear case.Type: ApplicationFiled: July 2, 2021Publication date: January 27, 2022Inventors: Daisuke KANEDA, Azumi KAMATA

Patent number: 10392787Abstract: A detachment sensor detects attachment and detachment of a water discharger to and from a retainer. An object sensor detects presence of an object. A controller causes water discharge triggered by detection of an object by the object sensor while the water discharger is attached to the retainer and suppresses water discharge triggered by detection of an object by the object sensor while the water discharger is detached from the retainer. The controller suppresses water discharge triggered by detection of an object by the object sensor after attachment of the water discharger to the retainer until a non-detection state of an object by the object sensor continues for a predetermined period of time.Type: GrantFiled: March 27, 2017Date of Patent: August 27, 2019Assignee: LIXIL CORPORATIONInventors: Azumi Kamata, Yuki Shirai, Mamoru Hashimoto

Patent number: 10072403Abstract: A human body sensor has a light emitting portion to emit light to an object, a light reception portion to receive the light reflected from the object, a light reception amount determiner, a distance measurement determiner, a moving object determiner, and a detection determiner. When an amount of the reflected light is a threshold or more under the detection state, the detection determiner determines to switch the determination from the detection state to the non-detection state under a condition that the distance measurement determiner determines that the detection target does not exist, and when an amount of the reflected light is less than the predetermined threshold under the detection state, the detection determiner determines to switch the determination from the detection state to the non-detection state under a condition that the moving object determiner determines that the object does not exist.Type: GrantFiled: June 13, 2013Date of Patent: September 11, 2018Assignee: Lixil CorporationInventors: Yuki Shirai, Azumi Kamata

Publication number: 20170247866Abstract: An automatic water faucet includes a spout pipe; a spout port member having a spout port, the spout port member being housed at a leading end of the spout pipe such that the spout port member can be freely pulled out; and a sensor provided in the vicinity of the spout port for causing water to start being discharged upon detecting an object underneath the spout port. The spout port member is configured to be pulled out from a side behind the sensor in an axial direction of the spout pipe.Type: ApplicationFiled: May 16, 2017Publication date: August 31, 2017Applicant: LIXIL CorporationInventors: Sachiko KESSOKU, Nobuaki ITAZU, Yuki SHIRAI, Yuichiro KOMATSU, Azumi KAMATA

Patent number: 9598846Abstract: An automatic water faucet includes: a water faucet; an imaging unit provided in a water discharge port of the water faucet and that images light reflected from a measure-distance target; a distance measurement unit that measures a distance from the imaging unit to the measure-distance target based on image data; a threshold setting unit that sets a threshold for distance; a detection unit that detects the measure-distance target as a detection object if the distance is shorter than the threshold set by the threshold setting unit; and a water supply control unit that causes the water faucet to discharge water in response to the detection unit detecting a detection object and causes the water faucet to stop supplying water in response to the detection unit not detecting a detection object. The threshold setting unit increases the threshold setting in response to the detection unit detecting a detection object.Type: GrantFiled: March 24, 2016Date of Patent: March 21, 2017Assignee: LIXIL CORPORATIONInventors: Yuki Shirai, Azumi Kamata

Publication number: 20150259890Abstract: A human body detection sensor having a high detection performance and an automatic faucet having high operational reliability are provided. The human body sensor 1 includes a distance measurement determiner 321 which determines the existence of the detection target depending on whether or not the distance index representing a distance to the detection target or a degree of the distance is included in a predetermined range, and a moving object determiner 322 which detects a temporal change of the reflected light entering the light reception portion 26 and determines whether or not the moving object exists.Type: ApplicationFiled: June 13, 2013Publication date: September 17, 2015Inventors: Yuki Shirai, Azumi Kamata
