Problems solved by technology

[0009] However, in the vehicle seat air conditioner disclosed in Patent Document 1, since the air volume of the air passing through the ventilation passage is small during the period when the temperature adjustment of the blown air is insufficient, the amount of heat per unit time moving from the air to the ventilation passage is smaller
Therefore, the temperature of the ventilation passage is not likely to approach the temperature of the air passing through the ventilation passage, and the time required for the air to be blown out to the occupants to reach a sufficiently regulated temperature may become longer.

Abstract

A control unit causes a blowout air switching device (24) to switch an air blowout portion (321) to a first blowout state if air blown from the air blowout portion (321) is in a pre-conditioned state. If air blown from the air blowout portion (321) is in a conditioned state, the control unit causes the blowout air switching device (24) to switch the air blowout portion (321) to a second blowout state. Furthermore, in the first blowout state, a first air outlet (321a) is opened while a second air outlet (321b) is closed. Conversely, in the second blowout state, the first air outlet (321a) is closed while the second air outlet (321b) is opened. Thus, it is possible to avoid blowing of insufficiently conditioned air against a seated person, without having to limit the volume of blowout air at the start of air-conditioning by a seat air-conditioner (10).

Description

[0001] Cross-reference of related applications [0002] This application is based on the JP Patent application 2013-222118 for which it applied on October 25, 2013, The indication of this application is referred and is used here. technical field [0003] The present invention relates to a vehicle seat air conditioner that blows air-conditioning air to a vehicle seat. Background technique [0004] As a conventional technology related to a vehicle seat air conditioner, for example, Patent Document 1 discloses a vehicle seat air conditioner in which air-conditioning air is blown from a plurality of fine holes formed in a seat surface. In the vehicle seat air conditioner of Patent Document 1, when the seat air conditioner is started when the vehicle interior is cooled or heated, the blown air velocity from the seat surface is limited so that the blown air velocity is 0.4 m / s or less. wind speed.
