Patent number: 10144265Abstract: An air conditioning unit for a vehicle has a casing, a heating heat exchanger, a first partition plate, a first opening, a second partition plate, a second opening, and a switching door. The casing has a face opening and a foot opening. The heating heat exchanger is arranged in the casing. The first partition plate partitions a downstream side of the heating heat exchanger in an airflow direction into a first passage and a second passage located below the first passage. The first opening is formed on a downstream side of the first partition plate in an airflow direction and communicates between the first passage and the second passage. The second partition plate is arranged on the downstream side of the heating heat exchanger and is formed with a third passage between the first partition plate and the second partition plate in the first passage.Type: GrantFiled: October 9, 2014Date of Patent: December 4, 2018Assignee: DENSO CORPORATIONInventors: Akinori Kuwayama, Shinichirou Hirai, Yasuhiro Sekito

Patent number: 9950589Abstract: A vehicle air conditioner includes a blower for blowing air into a space of a vehicle compartment, and an air-conditioning mode switching portion for switching between air conditioning modes. The air conditioning modes include a normal air conditioning mode in which air conditioning of a specific region including a driver seat and air conditioning of a non-specific region not including the specific region in the space of the vehicle compartment are performed, and a specific-region prioritizing air conditioning mode in which an air conditioning capability for the non-specific region is decreased as compared to the normal air conditioning mode. The air-conditioning mode switching portion adjusts the air conditioning capability for the non-specific region based on a pressure of air drawn into the blower, in the specific-region prioritizing air conditioning mode.Type: GrantFiled: December 1, 2011Date of Patent: April 24, 2018Assignee: DENSO CORPORATIONInventors: Yasuhiro Sagou, Manabu Maeda, Shinichirou Hirai, Yoshinori Yanagimachi, Koji Wakabayashi, Koji Ota

Patent number: 9834065Abstract: In an interior air conditioning unit, a divided case is provided with a main water receiver, a main drain port, a side wall, a secondary drain port, a partition wall, a notch, a droplet reservoir, a path, and a tilted portion. The side wall, the secondary drain port, the notch, the droplet reservoir, the path, and the tilted portion are respectively located such that a condensate water flows out of the main water receiver and reaches the secondary drain port through the notch before a water surface of the condensate water reaches a fitting portion between the divided cases. According to the above-described configuration, the condensate water produced in the cooling heat exchanger can be certainly prevented from leaking through the fitting portion of the air conditioning case.Type: GrantFiled: December 11, 2014Date of Patent: December 5, 2017Assignee: DENSO CORPORATIONInventors: Hirokazu Yamadaki, Shinichirou Hirai, Tomohiro Kamiya

Patent number: 9776474Abstract: A water discharge device that collects and drains condensed water generated in an air conditioning device includes: a drainage path along which condensed water is able to be drained in a draining state in which condensed water is expelled; and an opening and closing member that is able to block and open the drainage path. The opening and closing member blocks the drainage path so as to limit movement of air due to dynamic pressure when in a non-draining state other than the draining state. The opening and closing member drains condensed water through the drainage path when in the draining state.Type: GrantFiled: January 27, 2014Date of Patent: October 3, 2017Assignee: DENSO CORPORATIONInventors: Makoto Kume, Toshio Tsuboko, Seiji Kamei, Tomohiro Kamiya, Syun Omori, Hirokazu Yamadaki, Shinichirou Hirai

Patent number: 9188357Abstract: A vehicle air conditioner includes a heating heat exchanger, a first temperature adjustment mechanism for adjusting a temperature of air to be blown toward a driver's seat side in a vehicle compartment, and a second temperature adjustment mechanism for adjusting a temperature of air to be blown toward a front-passenger's seat side in the vehicle compartment. In the vehicle air conditioner, the first and second temperature adjustment mechanisms are controlled to perform a one-seat priority mode control such that the temperature of air to be blown toward the front-passenger's seat side is lower than the temperature of air to be blown toward the driver's seat side, when only the driver is in the vehicle compartment and the heating condition is determined as the air conditioning state.Type: GrantFiled: May 19, 2011Date of Patent: November 17, 2015Assignee: DENSO CORPORATIONInventors: Shinichirou Hirai, Yasuhiro Sagou, Manabu Maeda, Takuya Kataoka

Patent number: 8899311Abstract: When there is no occupant in seats other than a driver seat during a foot mode, an air-conditioning controller executes a single seat concentration mode to prevent blowing of warm air to a passenger seat and a backseat by closing foot outlets on a passenger seat side and a backseat side. In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature.Type: GrantFiled: November 15, 2010Date of Patent: December 2, 2014Assignee: Denso CorporationInventors: Haruki Misumi, Takuya Kataoka, Koji Ota, Michio Nishikawa, Shinichirou Hirai, Yoshiaki Suzuki, Akihiro Haraguchi, Katsuji Kuwada, Yasuhiro Sagou
