Problems solved by technology

[0008] In Patent Document 1, since the air-conditioning air is blown forward only from the headrest portion, the air-conditioning air passing behind the head is passed to the front of the occupant as it is, and there is a face supply that cannot be sufficiently sensitive to the warm feeling of the occupant. Condition of air conditioner
In addition, in Patent Document 1, since air-conditioning air is supplied only to the head, the supply of air-conditioning air to other body parts is not considered.
As described above, in the technique of Patent Document 1, there is room for improvement in terms of occupant comfort.

[0026] while referring to Figure 1 to Figure 5 The vehicle air conditioner according to the first embodiment will be described. Hereinafter, the vehicle width direction of a vehicle is only described as a width direction or a left-right direction. In addition, the height direction of a vehicle is only described as a height direction or an up-down direction. In addition, the front-back direction of a vehicle is only described as a front-back direction. The vehicle air conditioner 1 includes a first blowing duct 3 , a second blowing duct 4 , and a refrigeration cycle device 2 . The vehicular air conditioner 1 supplies an occupant with a feeling of coolness or warmth by supplying conditioned air as air whose temperature has been adjusted. In addition, the vehicle air conditioner 1 cools or heats the occupant's body by supplying air conditioning air.

[0027] The vehicle air conditioner 1 is applied to, for example, an electric vehicle that runs on electric power from a batte...

Abstract

A vehicular air conditioning device (1) has: a refrigeration cycle device (2) which generates temperature-adjusted conditioned air; and a first blow duct (3) provided with a first blowing port (33) from which conditioned air is blown so as to flow toward the front side of a seat and pass through the head portion of a passenger. The vehicular air conditioning device has a second blow duct (4) provided with a second blowing port (43) from which conditioned air is blown upward from a side lower than the first blowing port. From the second blowing port, conditioned air is blown out so as to pass through the waist portion of the passenger and joins the conditioned air blown from the first blowing port. The second blowing port blows conditioned air with a greater air amount than the first blowing port and guides the conditioned air blown from the first blowing port to flow along the face of the passenger. Thus, the comport of the passenger can be improved.
