Abstract: The present disclosure simplifies the H-bridge circuit of the direct current motor for driving the damper (door) that switches the air passages in the indoor unit of an air conditioning device. The control device for an air conditioner that takes in inside or outside air and conditions the air inside an air conditioning unit using an evaporator and a heater core is provided with: a first actuator and a second actuator that drive the multiple dampers installed inside the air conditioning unit for switching the air passages; and three half-bridge circuits that control the first actuator and the second actuator sharing one of the half-bridge circuits. Of the multiple dampers, the first actuator is connected to the inside/outside air switching damper. Of the multiple dampers, the second actuator is connected to at least one air mix damper.

Abstract: An opening and closing device includes a casing that defines an air passage, a slide door that includes a door main body slidable to open or close the air passage, and a sliding gear that is disposed on one side of the door main body in its width direction and includes first teeth in a sliding direction, and a drive gear that is rotatable around its axis line extending in the width direction and that includes second teeth in a circumferential direction around the axis line such that the first teeth and the second teeth are arranged in engagement with each other. When the drive gear rotates, a driving force is transmitted from the drive gear to the slide door through the sliding gear to slide the slide door. The door main body is restricted from shifting in the width direction due to the rotation of the drive gear.

Abstract: 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. The second opening that is located on a downstream side of the second partition plate in an airflow direction and communicates between an upper side and a lower side of the second partition plate. The switching door opens or closes the first and second openings. The air in the third passage is guided toward the foot opening by the second partition plate and the switching door in an air conditioning mode in which the switching door opens the first opening and closes the second opening.

Abstract: An air conditioning case includes a first partition wall that receives a condensed water generated by an evaporator, and the first partition wall is disposed above an overlapped portion of a heater core and between the evaporator and the heater core. Therefore, the first partition wall can prevent the condensed water dropped from the evaporator from being applied directly to the heater core. As a result, in a structure in which at least a portion of the heater core overlaps with the evaporator from below, the condensed water of the evaporator is less likely to be applied to the heater core.

Abstract: An air conditioner for a vehicle has a first shaft that drives a first air-mix door in conjunction with being rotated, a second shaft that drives a second air-mix door in conjunction with being rotated, and a rack that interlocks the first shaft and the second shaft with each other. The rack has an elongated shape, thereby a mounting space can be smaller with respect to a rink mechanism. Therefore, an air conditioning unit can be downsized.

Abstract: A heater core is disposed to be inclined with respect to an airflow direction so that a first header tank unit is displaced downstream of a second header tank unit in the airflow direction. Therefore, when a first air mixing door blocks a first heating portion, an air stagnates between a downstream lateral portion of the first heating portion and a second partition wall downstream of the first heating portion, and the air is unlikely to be heated downstream of the first heating portion. Likewise, the air is unlikely to be heated upstream of a second heating portion in a second airflow passage. Therefore, a maximum cooling performance of a vehicle air conditioning unit can be restrained from being deteriorated due to a heat from a heater core.
