Publication number: 20210245575Abstract: An airflow generating device includes an airflow generating portion, a duct, and a controller. The airflow generating portion is configured to generate an airflow. The duct is configured to guide the airflow to a blowing outlet through which the airflow is blown out toward a passenger in a vehicle cabin. The controller is configured to cause the airflow to be intermittently blown out through the blowing outlet by controlling a frequency of a pulse voltage applied to the air flow generating portion and a duty ratio of a pulse width to a pulse period of the pulse voltage. The controller is configured to control the duty ratio and the frequency of the voltage such that the airflow is blown out through the blowing outlet at a speed between a predetermined lower limit, inclusive, and a maximum lower limit, non-inclusive, which is greater than the lower limit.Type: ApplicationFiled: April 26, 2021Publication date: August 12, 2021Inventors: Etsuro YOSHINO, Yasuhiro TAKEUCHI, Yuuji OKAMURA, Jun YAMAOKA, Masaharu SAKAI, Yusuke KOMATSUBARA, Kazushi SHIKATA, Yasuhiko NIIMI

Publication number: 20210046806Abstract: A blowing device includes a passage member and a passage switching device. The passage member is inserted into an air passage configured to blow a main air into the vehicle cabin. The passage member is configured to blow an added-value air. The passage member includes, in the air passage, a passage opening portion through which the added-value air is blown toward a passenger separately from the main air. The passage member defines a hole portion and the passage switching device is a damper or a rotary door. The damper or the rotary door closes the hole portion to allow the added-value air to flow out through the passage opening portion and fluidly connects the hole portion to the air passage to allow the main air to flow out through both the passage opening portion and a region of the air passage other than the passage opening portion.Type: ApplicationFiled: November 3, 2020Publication date: February 18, 2021Applicant: DENSO CORPORATIONInventors: Yusuke KOMATSUBARA, Hitoshi NINOMIYA, Kazushi SHIKATA, Takahito NAKAMURA

Patent number: 6918262Abstract: An air conditioning system includes an air conditioner for blowing conditioned air toward a compartment of a vehicle, and a dashboard having a design surface exposed to the compartment. An inner air passage extending nearly parallel to the design surface is formed in the dashboard, and a plurality of diffusion blowing openings are formed in the design surface. Thus, the condensed air is blown from the diffusion blowing openings into the compartment of the vehicle, while passing through the inner air passage. For example, cool air is blown from the diffusion blowing openings, so that the cool air can cool the dashboard while cooling the compartment of the vehicle. Moreover, because the cool air passes through the inner air passage extending nearly parallel to the design surface, the dashboard can be effectively cooled.Type: GrantFiled: August 8, 2003Date of Patent: July 19, 2005Assignee: DENSO CorporationInventors: Tomohiro Kamiya, Koichi Ito, Kazushi Shikata, Masafumi Kawashima, Yasuyuki Nishi

Patent number: 6877550Abstract: In a vehicle air conditioner, an evaporator is disposed at an upper side of a blower approximately horizontally so that air blown by the blower passes through the evaporator from below upwardly. The evaporator is slightly tilted from a horizontal surface by a predetermined angle, and the blower is disposed in such a manner that air is mainly blown by the blower toward the evaporator in a direction substantially parallel to a tangential line at a scroll finish portion of the scroll casing. Accordingly, condensed water on a bottom heat-exchanging surface of the evaporator can be pushed downwardly by component force of the flow of air mainly blown from the blower.Type: GrantFiled: April 17, 2003Date of Patent: April 12, 2005Assignee: DENSO CorporationInventors: Kazushi Shikata, Satoshi Mizutani, Tomohiro Kamiya
