Description

Independent Air Conditioning Seat for Vehicle The present invention relates to an independent air conditioning seat for a vehicle, and more specifically, to an independent air conditioning seat for a vehicle that forms an air curtain that surrounds the body of a passenger seated in the seat. An independent air conditioning seat for vehicles (hereinafter referred to as the 'independent air conditioning seat') has been developed to improve the energy efficiency of electric vehicles and provide air conditioning comfort for individual passengers. The above-mentioned independent air conditioning seat was able to create an independent air conditioning atmosphere for the passenger seated in the seat by allowing air (cold air, warm air, or simple ventilation) to be emitted from multiple parts around the perimeter of the seat through air passages (ducts) provided inside the seat. In other words, the above-mentioned independent air conditioning seat promotes more efficient independent air conditioning by forming an air curtain that surrounds the passenger. However, conventional independent air-conditioned seats have a problem in that, although air is discharged from the seat's outlets to the inner part of the seat (passenger seating space), they are unable to form an optimal air curtain that sufficiently envelops the passenger's body parts corresponding to each outlet. Conventional technology refers to technical information that the inventor possessed for the derivation of the present invention or acquired during the process of deriving the present invention, and it cannot necessarily be considered publicly known technology disclosed to the general public prior to the filing of the present invention. FIG. 1 is a perspective view of an independent air conditioning seat for a vehicle according to an embodiment of the present invention. FIG. 2 is a schematic cross-sectional view of a discharge member, which is a component of the above-mentioned independent air conditioning sheet. FIGS. 3 and 4 are cross-sectional views showing multiple test examples of the upper discharge member among the discharge members and graphs of test results for each test example. FIGS. 5 and 6 are cross-sectional views showing multiple test examples of intermediate discharge members among the discharge members and graphs of test results for each test example. FIGS. 7 and 8 are cross-sectional views showing multiple test examples of the lower discharge member among the discharge members and graphs of test results for each test example. In the present invention, the attached drawings may be illustrated with exaggerated expressions to distinguish it from the prior art, ensure clarity, and facilitate the understanding of the technology. Furthermore, the terms described below are defined considering their functions in the present invention; since these terms may vary depending on the intentions or conventions of the user or operator, their definitions should be based on the technical content throughout this specification. Meanwhile, the embodiments are merely exemplary details of the components presented in the claims of the present invention and do not limit the scope of the rights of the present invention; the scope of rights should be interpreted based on the technical concept throughout the specification of the present invention. Throughout the specification, when a configuration is described as "including" a configuration, this means that, unless specifically stated otherwise, it does not exclude other configurations but may include additional configurations. Furthermore, when it is said that one configuration is "connected," "connected," or "combined" with another configuration, this means that it is not only "directly connected," "directly connected," or "directly combined," but also that there may be cases where it is "connected with another configuration interposed," "connected with another configuration interposed," or "combined with another configuration interposed." On the other hand, when it is said that one configuration is "directly connected," "directly connected," or "directly combined" with another configuration, it should be understood that there is no other configuration in between. In addition, when directional terms such as "front," "back," "up," "down," "left," "right," "first end," "other end," and "both ends" are used, they are used exemplarily in relation to the orientation of the disclosed drawings and should not be interpreted restrictively, and when terms such as "first" and "second" are used, they are terms used to distinguish each configuration and should not be interpreted restrictively. In order to more clearly explain the features of the embodiments of the present invention, detailed descriptions of matters widely known to those skilled in the art to which the following embodiments pertain are omitted. Additionally, detailed descriptions of parts in the drawings that are unrelated to the description of the embodimen
