Patent number: 11091004Abstract: An air conditioning unit includes an air conditioning case, a connector that is attached to an end of a first pipe connected to a first heat exchanger, a second pipe connected to a second heat exchanger, and a gasket being a sheet in shape. The gasket includes a first opening and a second opening. The gasket is adhered to a contact surface of the air conditioning case with the connector inserted into the first opening and with the second pipe inserted into the second opening. The periphery of the second opening in the gasket is compressed by the second pipe. The gasket includes a surface including an adhesive area that includes at least a periphery of the first opening and an adhesive-less area that includes at least a periphery of the second opening. The adhesive is applied to the adhesive area and is not applied to the adhesive-less area.Type: GrantFiled: November 23, 2016Date of Patent: August 17, 2021Assignee: DENSO CORPORATIONInventors: Shunsuke Takahira, Yohei Shimoyama

Patent number: 11027588Abstract: An air conditioner for a vehicle includes an air conditioning case and a case interior member in the air conditioning case. The case interior member includes a tunnel member and a tunnel exterior guide wall. The tunnel member defines a tunnel channel therein and is arranged in a downstream space defined in an air conditioning case. The tunnel exterior guide wall is configured to guide an air to flow from a warm air passage to an outside of the tunnel channel. A first direction along which the tunnel exterior guide wall extends is closer to a direction, which is opposite to the one direction along which the air flowing from a cool air passage into the downstream space, as compared to a second direction along which the tunnel guide wall extends.Type: GrantFiled: January 25, 2017Date of Patent: June 8, 2021Assignee: DENSO CORPORATIONInventor: Yohei Shimoyama

Patent number: 10899193Abstract: An air conditioning case defines a warm air passage, a cool air passage, a first space, and a second space therein. The cool air passage is in communication with the first space. The warm air passage is in communication with the first space. The second space is connected to the first space on a side of the first space away from the cool air passage. A case interior member including a tunnel member and a blade is arranged in the first space. The tunnel member includes an upstream-end forming portion and a downstream-end forming portion. The upstream-end forming portion is open to the warm air passage. The downstream-end forming portion is open in a direction away from the upstream-end forming portion. The blade extends from the downstream-end forming portion to both sides along a width direction, and guides the air from the tunnel channel to diffuse along the width direction.Type: GrantFiled: January 25, 2017Date of Patent: January 26, 2021Assignee: DENSO CORPORATIONInventor: Yohei Shimoyama

Patent number: 10800226Abstract: An air conditioning unit for a vehicle includes an air conditioning case, a blower, a cooler including a core, and a drain port that drains condensed water generated in the cooler from the air conditioning case. A bottom surface of the air conditioning case defines a drain path extending from a boundary between the blower and the air conditioning case to the drain port. The drain path is inclined downward toward the drain port. A backflow prevention rib protrudes from the bottom surface to extend along a direction intersecting with a width direction of the air conditioning case. The backflow prevention rib is configured to guide the condensed water to the drain port. The backflow prevention rib is located below a virtual line that extends from the boundary to a lower end of an upstream surface of the core.Type: GrantFiled: January 25, 2017Date of Patent: October 13, 2020Assignee: DENSO CORPORATIONInventors: Yohei Shimoyama, Masayuki Narita

Patent number: 10493817Abstract: A partition seal portion of a second rotary door is located between an outer door portion and a partition rib. The partition seal member is pressed against a rib tip portion in a door radial direction and moves slidably while being in contact with the rib tip portion in conjunction with a rotation of the second rotary door. Accordingly, an increase of a width in a door axial direction required for a sealing configuration can be suppressed. Therefore, a seal between a side face outlet and a center face outlet can be secured while being preventing a length of a face outlet in the door axial direction from being short.Type: GrantFiled: November 28, 2014Date of Patent: December 3, 2019Assignee: DENSO CORPORATIONInventors: Yohei Shimoyama, Shuhei Yonemitsu
