摘要： [Object] An object of the present disclosure is to provide a heating control device, a heating cycle device, and a vehicle air conditioner including the same, by which a target temperature can be early reached and a fluctuation of a temperature with respect to the target temperature can be controlled to be small.
[Solution] A heating control device 6 according to the present disclosure is a heating control device that controls a transistor 5 that supplies electric power by a switching operation to a heater 4 that heats a coolant. The heating control device adjusts a heating amount from the heater based on a heating amount control profile. The heating amount control profile includes a decrease portion in which the heating amount decreases as a temperature of the coolant increases. The decrease portion includes a first decrease portion and a second decrease portion each having a negative slope, and the first decrease portion and the second decrease portion have the same heating amount at a target temperature. The first decrease portion includes a first region and a second region, and as negative slopes, a slope at any temperature in the second region is larger than a slope at any temperature in the first region.

摘要： A vehicle-use air conditioning device that supplies air to a side vent aperture portion regardless of a discharge mode, and allows a discharge of air from a defrost aperture portion when a discharge mode that maximizes a ratio of air blown to a passage communicating with a foot aperture portion is employed, is such that a change in an amount of air supplied from the defrost aperture portion is restricted using a simple structure that does not necessitate fine adjustment, even when an air passage on a downstream side of the side vent aperture portion is closed. A passage (a third passage 23) communicating with a side vent aperture portion 17b to a downstream side of heat exchangers 6, 7 is configured of a passage that, when a rotary type first door 25 that adjusts ratios of air blown to a first passage 21 communicating with a foot aperture portion 18 and a second passage 22 communicating with a defrost aperture portion 16 and a center vent aperture portion 17a is in a discharge mode position that maximizes the ratio of air blown to the first passage 21, connects a region to an upstream side of the first door 25 and the side vent aperture portion 17b, regardless of a discharge mode.

摘要： An object is to provide an electric compressor reinforcement structure such that when a mounting leg is formed on an outer face of a cover that an inverter housing has on an endmost side in an axial direction of an electric compressor, a space in the inverter housing is not crushed even when a strong force acts on the electric compressor due to a collision or the like at a front of a vehicle. A housing 6 of an electric compressor 1 has an inverter housing 9 that is formed of a side wall portion 91 and a partitioning wall 92 and in which an inverter device 5 is housed, the inverter housing 9 is closed to a front of the electric compressor 1 by a cover 10 on which a mounting leg 103 is formed, and a hollow protruding portion 104 protruding in a dome form centered on the mounting leg 103 is provided on an outer face of the cover 10, whereby a load exerted from the front of the electric compressor 1 is dispersed to prevent the space in the inverter housing 9 from being crushed.
