Problems solved by technology

[0013] However, since after the auxiliary door 70 is assembled on the rotating shaft 63a of the indoor-outdoor air switching door 63 in the form of a flap, the upper end of the indoor-outdoor air switching door 63 is fixed to the rotating shaft 63a by using a separate fixing screw 64. , so that the indoor and outdoor air switching door 63 and the auxiliary door 70 are independently rotated, and thus the blower according to the prior art has some disadvantages in that the number of parts is unnecessarily increased, the assembling work is complicated, and it is reduced due to an increase in manufacturing cost. increased productivity
[0014] In addition, as mentioned above, since the indoor air introduction structure using the auxiliary door 70 in the outdoor air inflow mode can only be applied to the indoor-outdoor air switching door 63 of the plate type, and the indoor-outdoor air switching door 63 of the arch type or other types (cylindrical type, hemispherical type) Indoor and outdoor air switching doors cannot be applied, so indoor air cannot be introduced in outdoor air inflow mode, thus deteriorating heating performance

Abstract

The invention relates to a vehicle blower. The blower has an auxiliary door formed on the upper end of the filter cover to open and close the indoor air inlet, thereby allowing part of the indoor air to flow into the blower in the outdoor air inflow mode regardless of the type of the indoor-outdoor air switching door. to improve heating performance, thereby increasing productivity and reducing manufacturing costs.

Description

technical field [0001] The present invention relates to a vehicular blower, and more particularly, to a vehicular blower having an auxiliary door formed on an upper end portion of a filter cover to open and close an indoor air inlet, thereby Regardless of the type of air switching door (plate type, arch type or other type), it allows part of the indoor air to flow into the blower in the outdoor air inflow mode, which improves the heating performance, and improves productivity and reduces manufacturing due to simple installation and structure. cost. Background technique [0002] Generally, an air conditioner for a vehicle is designed to introduce indoor / outdoor air of a vehicle and heat or cool it, thereby blowing the heated or cooled air into the interior of the vehicle, thereby heating or cooling the interior of the vehicle. [0003] Such as figure 1 As shown, the air conditioner includes: a blower 10 having an indoor air inlet 21 and an outdoor air inlet 22 formed at one...
