Publication number: 20240032749Abstract: A cleaning tool includes: a body including an upper case and a lower case, and for sucking dust from the surface to be cleaned from the lower case; and a joint located at one end side of the body with respect to a center of the body in a longitudinal direction of the body. The joint includes a first rotating portion and a second rotating portion. The second rotating portion is connected to the body so as to be rotatable relative to the body around a second axis of rotation being parallel to the longitudinal direction of the body. The first rotating portion is rotatably connected to the second rotating portion so as to be rotatable relative to the second rotating portion around a first axis of rotation being at an intersecting position or a skewed position with respect to the second axis of rotation.Type: ApplicationFiled: September 29, 2023Publication date: February 1, 2024Inventors: Yohei ASAHI, Koshiro TAKANO, Marika HARAMAKI, Kimiyoshi SOMA

Patent number: 11819179Abstract: A cleaning tool includes a body for sucking in dust on a surface to be cleaned, a suction pipe, and a joint for connecting the suction pipe to the body. The joint is positioned closer to one end of the body with respect to a center of the body in a longitudinal direction of the body and is positioned substantially at center in a direction perpendicular to the longitudinal direction. A second rotating portion of the joint is connected to the body so as to be rotatable around a second axis of rotation being substantially parallel to the longitudinal direction. A first rotating portion of the joint is rotatably connected to the second rotating portion so as to be rotatable relative to the second rotating portion around a first axis of rotation being at an intersecting position or a skewed position with respect to the second axis of rotation.Type: GrantFiled: May 25, 2021Date of Patent: November 21, 2023Assignee: Mitsubishi Electric CorporationInventors: Yohei Asahi, Koshiro Takano, Marika Haramaki, Kimiyoshi Soma

Publication number: 20230258365Abstract: An environment control system includes a louver (20a), a motor (21), a temperature sensor (40), a determination unit (53), and a control unit (55). The determination unit (53) determines a position of a person in a particular area on the basis of data of surface temperatures detected by the temperature sensor (40). The control unit (55) controls the motor (21) in such a manner that an angular velocity of the louver (20a) becomes smaller as the position determined by the determination unit (53) is farther from the outlet (18b) when air from an outlet (18b) is blown toward the position.Type: ApplicationFiled: June 2, 2020Publication date: August 17, 2023Inventors: Kohei HISANO, Mari ORITO, Takuya FURUHASHI, Ryo FUSHIE, Satoshi MINEZAWA, Marika HARAMAKI

Publication number: 20230151995Abstract: An environmental control system includes an air conditioner body (1), a human body detector for detecting a human body, and a system controller for controlling the air conditioner body (1). The system controller executes a first control when a distance from a human body detected by the human body detector to the air conditioner body (1) is a first distance, and executes a second control when a distance from a human body detected by the human body detector to the air conditioner body (1) is a second distance larger than the first distance. The air conditioner body (1) blows air from one of the air outlets 20 toward the human body detected by the human body detector when the first control is executed, and blows air from at least two air outlets (20) toward a human body detected by the human body detector when the second control is executed.Type: ApplicationFiled: June 2, 2020Publication date: May 18, 2023Inventors: Marika HARAMAKI, Mari ORITO, Ryo FUSHIE, Kohei HISANO, Satoshi MINEZAWA, Takuya FURUHASHI

Publication number: 20210274988Abstract: A cleaning tool includes a body for sucking in dust on a surface to be cleaned, a suction pipe, and a joint for connecting the suction pipe to the body. The joint is positioned closer to one end of the body with respect to a center of the body in a longitudinal direction of the body and is positioned substantially at center in a direction perpendicular to the longitudinal direction. A second rotating portion of the joint is connected to the body so as to be rotatable around a second axis of rotation being substantially parallel to the longitudinal direction. A first rotating portion of the joint is rotatably connected to the second rotating portion so as to be rotatable relative to the second rotating portion around a first axis of rotation being at an intersecting position or a skewed position with respect to the second axis of rotation.Type: ApplicationFiled: May 25, 2021Publication date: September 9, 2021Inventors: Yohei ASAHI, Koshiro TAKANO, Marika HARAMAKI, Kimiyoshi SOMA

Patent number: 11045055Abstract: A body included in a cleaning tool has a proximal end, a distal end, and a bottom surface that faces a surface to be cleaned when in use. A length from the proximal end to the distal end is longer than a width perpendicular to a longitudinal direction from the proximal end toward the distal end. A joint that connects a suction pipe being a wand to the body is positioned closer to the proximal end than to the distal end. The joint enables a first angle being an angle of a longitudinal axis of the wand with respect to the longitudinal direction of the body to be changed. The cleaning tool includes a locking mechanism that, when the first angle is equal to a holding angle of 90° or less, prevents the first angle from changing from the holding angle to a different angle.Type: GrantFiled: November 2, 2015Date of Patent: June 29, 2021Assignee: Mitsubishi Electric CorporationInventors: Yohei Asahi, Koshiro Takano, Marika Haramaki, Kimiyoshi Soma

Patent number: 10856713Abstract: A cleaner head for a vacuum cleaner includes: a body having a proximal end and a distal end; an agitator, an axis of rotation R1 of the agitator being substantially parallel to a longitudinal direction of the body; a motor configured to cause the agitator to rotate; and a joint configured to turnably connect a suction pipe to the body. The joint is positioned closer to the proximal end than to the distal end. The body includes a second suction channel configured to communicate with a first suction channel inside the joint, and a bulkhead configured to separate an agitator chamber and the second suction channel from each other. The second suction channel extends substantially parallel to the axis of rotation of the agitator. The bulkhead includes at least one air vent from the agitator chamber to the second suction channel.Type: GrantFiled: October 22, 2015Date of Patent: December 8, 2020Assignees: Mitsubishi Electric Corporation, Mitsubishi Electric Home Appliance Co., Ltd.Inventors: Yohei Asahi, Koshiro Takano, Marika Haramaki, Kimiyoshi Soma

Patent number: 10813511Abstract: There is provided an electric vacuum cleaner capable of further cleaning up air discharged from a whirling chamber which swirls air to separate dust from the air by inertial force, as well as capable of downsizing the electric vacuum cleaner's body. To this end, the electric vacuum cleaner includes: a whirling chamber configured to swirl air containing dust around a central axis to separate dust from the air containing dust, the whirling chamber having a discharge port for discharging air in the whirling chamber; a discharge pipe provided in the whirling chamber along the central axis, the discharge pipe communicating with the discharge port; and a filter provided on a downstream side of the discharge port. The filter is positioned outside of the discharge pipe on a projection plane perpendicular to the central axis.Type: GrantFiled: January 8, 2016Date of Patent: October 27, 2020Assignees: Mitsubishi Electric Corporation, Mitsubishi Electric Home Appliance Co., Ltd.Inventors: Koshiro Takano, Marika Haramaki, Yohei Asahi, Kimiyoshi Soma
