Patent number: 9777940Abstract: An air conditioning indoor unit includes a casing having an air outlet, a horizontal blade, a Coanda blade and a control unit. The horizontal blade changes an up and down direction flow of outlet air blown out from the air outlet. The Coanda blade cooperates with the horizontal blade in order to utilize the Coanda effect to change the outlet air to a Coanda airflow along a predetermined surface. The control unit changes postures of the Coanda blade and the horizontal blade to predetermined postures that change some of the outlet air to the Coanda airflow and do not change a remainder of the outlet air to the Coanda airflow.Type: GrantFiled: August 31, 2012Date of Patent: October 3, 2017Assignee: Daikin Industries, Ltd.Inventor: Masanao Yasutomi

Patent number: 9644860Abstract: An air-conditioning indoor unit includes a blow-out port, a Coanda vane and a controller. The Coanda vane is-provided in proximity to the blow-out port. The Coanda vane turns the blown air into a Coanda airflow along a bottom surface of the Coanda vane. The controller performs a control in which a direction of the Coanda airflow is directed in a first direction by positioning the Coanda vane in a first orientation, and the direction of the Coanda airflow is directed in a second direction different from the first direction by positioning the Coanda vane in a second orientation different from the first orientation.Type: GrantFiled: October 2, 2012Date of Patent: May 9, 2017Assignee: Daikin Industries, Ltd.Inventors: Masanao Yasutomi, Masashi Kamada

Patent number: 9593864Abstract: An air-conditioning indoor unit causes a flow of air blown out from a blow-out port to be diverted in a predetermined direction due to the Coand{hacek over (a)} effect. The air-conditioning indoor unit includes an airflow direction adjustment vane varying a blowout angle of blown air relative to a horizontal plane, a Coand{hacek over (a)} vane turning the blown air into a Coand{hacek over (a)} airflow along a bottom surface, and a control unit. The Coand{hacek over (a)} vane is provided in proximity to the blow-out port. The control unit executes an airflow direction automatic switching mode automatically switching between a Coand{hacek over (a)} effect use state in which the blown air is turned into a Coand{hacek over (a)} airflow along a predetermined surface and diverted in the predetermined direction, and a normal state in which the Coand{hacek over (a)} airflow is not created.Type: GrantFiled: August 31, 2012Date of Patent: March 14, 2017Assignee: Daikin Industries, Ltd.Inventors: Masanao Yasutomi, Masashi Kamada

Patent number: 9494329Abstract: An air conditioning indoor unit includes a casing having an air outlet, a horizontal blade that changes an up and down direction flow of outlet air, a Coanda blade to change the outlet air to a Coanda airflow along an undersurface of the Coanda blade, and a control unit. The control unit adjusts a relative angle between the Coanda blade and the horizontal blade to selectively use either of a first airflow state and a second airflow state. In the first airflow state, the control unit adjusts the relative angle to a predetermined angle in a first angular range to produce the Coanda airflow on substantially an entire region of the undersurface of the Coanda blade. In the second airflow state, the control unit adjusts the relative angle to a predetermined angle in a second angular range larger than the first angular range to not produce the Coanda airflow.Type: GrantFiled: December 26, 2012Date of Patent: November 15, 2016Assignee: Daikin Industries, Ltd.Inventor: Masanao Yasutomi

Patent number: 9488381Abstract: An air-conditioning indoor unit is operable in a Coanda effect use mode in which blown air from a blow-out port is diverted in a predetermined direction. The indoor unit includes a scroll leading conditioned air to the blow-out port, a Coanda vane in proximity to the blow-out port, and a controller controlling orientation of the Coanda vane. The Coanda vane alters an airflow direction of the blown air via the Coanda effect and turns the blown air into a Coanda airflow along a bottom surface of the Coanda vane. A convex shaped curved surface formed in the bottom surface of the Coanda vane has a radius of 50 to 300 mm. The controller adjusts the orientation of the Coanda vane away from a casing front surface as the Coanda vane separates from the blow-out port in the Coanda effect use mode.Type: GrantFiled: October 2, 2012Date of Patent: November 8, 2016Assignee: Daikin Industries, Ltd.Inventors: Masanao Yasutomi, Masashi Kamada

Publication number: 20160076786Abstract: An air conditioning indoor unit includes a movable first air direction adjustment plate that changes an up and down direction of the outlet air, a second air direction adjustment plate disposed adjacent to the air outlet, and a control unit that controls postures of the first and second adjustment plates. The second adjustment plate has at least a front end portion housed in an indoor unit front portion outside a blowing path when housed. In a Coanda effect utilization mode the control unit controls the postures of the first and second adjustment plates such that the second adjustment plate is spaced apart from the indoor unit front portion and a height position of a rear end portion is lower than when operation is stopped, and the adjustment plates form a predetermined angle to change the outlet air to a Coanda air flow along an undersurface of the second adjustment plate.Type: ApplicationFiled: November 24, 2015Publication date: March 17, 2016Inventors: Masanao YASUTOMI, Takahiro OKAMOTO, Masashi KAMADA, Hironobu TERAOKA, Noriyuki OKUDA
