Patent number: 10561284Abstract: A hand dryer includes an air-stream generating device including a device air inlet, an inner housing that accommodates therein the air-stream generating device and has an inner air inlet formed in an intake surface thereof, and an outer housing that accommodates therein the inner housing and the air-stream generating device and has an outer air inlet formed therein. An intake air passage that connects the outer air inlet and the device air inlet to each other is formed inside the outer housing to include the intake surface and an opposing surface as a portion of a wall surface thereof, and a projection is provided on the opposing surface to project from a region that is opposed to the inner air inlet towards the intake surface. The projection has a first surface facing an upstream side in the intake air passage.Type: GrantFiled: July 24, 2015Date of Patent: February 18, 2020Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Kazuki Okamoto, Takaki Kobayashi, Yasuyuki Itoigawa, Yukimichi Imai

Patent number: 8201344Abstract: A hand drying apparatus includes a high-pressure airflow generator that takes air through an air inlet and generates a high-pressure airflow, a main body casing, a first air path that is protruded from the main body casing, and a nozzle that is located in a position ahead of the main body casing in a direction of the first air path. The main body casing includes a main-body air inlet through which outside air is taken and a second air path that causes air from the main-body air inlet to flow upward and then downward to a level where the air inlet of the high-pressure airflow generator is located.Type: GrantFiled: June 18, 2008Date of Patent: June 19, 2012Assignee: Mitsubishi Electric CorporationInventors: Kenji Sawabe, Manabu Fukano, Shigeki Nishimura, Yasuyuki Itoigawa

Patent number: 7657162Abstract: A hand inserting portion is opened at one surface of a casing or at both the one surface and other surface of the casing. The hand inserting portion includes a space in which hands can be accommodated. A high-pressure-airstream generating unit generates a high-speed airstream. A nozzle is provided on each of two opposing sides of the hand inserting portion, from which the high-speed airstream is jetted into the space of the hand inserting portion. The nozzle includes a hole array formed by arranging a plurality of nozzle holes in a row. Air volume of the high-speed airstream is larger at a central portion of the hole array than at other portions of the hole array.Type: GrantFiled: May 2, 2007Date of Patent: February 2, 2010Assignee: Mitsubishi Electric CorporationInventors: Yasuyuki Itoigawa, Keiji Kameishi
