Patent number: 11214113Abstract: A vehicular air conditioning device includes an air conditioning case having first, second case introduction ports and first, second case discharge ports, and a fan. The first, second case discharge ports are offset upward and downward in an up-down direction relative to a rotation axis, respectively. A first inner guide surface of an inner guide plate is located on the one side of a second inner guide surface in the left-right direction. Air introduced through the first case introduction port is guided by the first inner guide surface to be drawn from a first passage into the fan, the air being blown upward to flow through the first case discharge port.

Patent number: 10926604Abstract: An air conditioner for performing air-conditioning of an interior of a vehicle cabin includes a casing, an evaporator, a blower, a controller, and a cooling passage. The casing defines a ventilation passage through which air flows from an air introduction port toward an air outlet. The evaporator cools the air flowing through the ventilation passage. The blower is disposed on a downstream side with respect to the evaporator in the ventilation passage and generates an airflow in the ventilation passage. The controller controls an output from the blower. The cooling passage causes a position located on a downstream side with respect to the blower in the ventilation passage to communicate with a position located on an upstream side with respect to the evaporator in the ventilation passage. A controller is installed in the cooling passage.Type: GrantFiled: February 23, 2017Date of Patent: February 23, 2021Assignee: DENSO CORPORATIONInventors: Ryo Kobayashi, Yoshihiko Okumura, Yasuhiro Sekito, Shinya Kato, Tetsuya Kono, Yuki Tsumagari, Kira Oiwa
