7. Blow Passage The air passage member 21 of the blower unit 2 is configured with inner peripheral wall portions 733A and 733B so as to prevent unevenness of the air blown out from the blower fan 22 . In addition, by reducing unevenness of the air, for example, air can be evenly supplied to the heater 31, and warm air with little temperature unevenness can be blown out from the blower outlet 11a.
Description will be made below with reference to FIG.

The duct portion 213 is composed of the first member 7A and the second member 7B, but when the duct portion 213 is described, the first member 7A and the second member 7B are integrated. , without "A" or "B" in the code. For example, the inner peripheral wall portion of the duct portion 213 is formed from the inner peripheral wall portion 733A of the first member 7A and the inner peripheral wall portion 733B of the second member 7B to the tongue portion of the tongue portion 735A of the first member 7A and the second member 7B. 735B and the tongue portion 735B, they are simply described as the inner peripheral wall portion 733 and the tongue portion 735, and are not labeled with "A" or "B" in FIG. 9 either.
A rotation-side end 215 a of the communication port 215 is also the upstream end of the inner peripheral wall portion 733 and the tip of the tongue portion 735 . 215a and 215b are also used for the ends of the communication port 215. As shown in FIG.
In the cross section perpendicular to the rotation axis O of the blower fan 22, the inner peripheral wall portion 733 is such that the airflow passing through the vicinity of the tongue portion 735 or the upstream end portion of the tongue portion 735 and the inner peripheral wall portion 733 reaches the inner surface of the inner peripheral wall portion 733. ) is configured to flow along the At this time, the duct portion 213 is not provided with a guide portion for guiding the flow of the air from the blower fan 22 , so that the air flows along the inner peripheral wall portion 733 . It should be noted that the reason why the air flows along the inner peripheral wall portion 733 without providing a guide portion is to utilize the Coanda effect.

Here, the air is exhausted forward (first direction) from the exhaust port 213a of the duct portion 213 . The duct portion 213 curves upward from the communication port 215 and then curves forward. The inner peripheral wall portion 733 has a flat portion 733a extending from the rotation side end 215a of the communication port 215 toward the exhaust port 213a. For the sake of convenience, the flat portion 733a is referred to as a first flat portion 733a in order to distinguish it from a (second) flat portion 733b, which will be described later.
The first flat portion 733a has a substantially linear shape in a cross section perpendicular to the rotation axis O. As shown in FIG. The angle A between the first flat portion 733a and the tangent line L1, which is a tangent line that is in contact with the outer circumference of the blower fan 22 and passes through the rotation-side end 215a, forms an upward (virtual line L2 that extends upward) with the first flat portion 733a. ) is smaller than the angle B between The angle B between the upward direction and the first flat portion 733a is set to 40 to 50 degrees. Thereby, the airflow in the vicinity of the inner peripheral wall portion 733 can be effectively attracted.
The length D2 of the first flat portion 733a is set to 40 to 60 mm in a cross section orthogonal to the rotation axis O. This length is 40-60% of the length of the communication port 215 . As a result, the air smoothly flows along the inner peripheral wall portion 733 and flows toward the exhaust port 213a.

The end portion of the inner peripheral wall portion 733 on the side of the communication port 215, that is, the upstream end portion of the first flat portion 733a is positioned forward of the rear end of the outer periphery of the blower fan 22 in the front-rear direction. The distance D1 between the upstream end of the first flat portion 733a (tip of the tongue portion 735) and an imaginary line L3 passing through the rotation axis O and parallel to the upward direction is It is 60 to 75% of the radius r of the outer circumference. As a result, the communication port 215 of the air blowing passage can be narrowed, the speed range from the airflow speed before passing through the communication port 215 to the airflow speed after passing through the communication port 215 can be secured, and the inner peripheral wall can be closed after passing through the communication port 215. The airflow becomes easier to flow along the portion 733, and the traveling direction of the airflow can be changed.
The tip portion side of the tongue portion 735 and the upstream end portion side of the inner peripheral wall portion 733 are rounded, and the radius of curvature is set within the range of 2 to 5 mm. As a result, the airflow can be drawn from the tongue portion 735 to the upstream side of the inner peripheral wall portion 733, and the advancing direction of the airflow can be changed toward the exhaust port 213a. In addition, air can flow smoothly around the tip of the tongue portion 735 , that is, the vicinity of the rotation-side end portion 215 a of the communication port 215 .

The inner peripheral wall portion 733 has a first flat portion 733a and a second flat portion 733b extending forward from the downstream end of the first flat portion 733a. The second flat portion 733b here is composed of the upstream member 35 of the heating unit 3 and the lower plate portions 351a, 341c of the frame-shaped portions 351, 341 of the downstream member 34. As shown in FIG. The second flat portion 733b may extend parallel to the forward direction, or may be inclined with respect to the forward direction within a range of -10 to 10 degrees. Also, the angle C between the first flat portion 733a and the second flat portion 733b is set within the range of 120 to 150 degrees. As a result, the traveling direction of the airflow can be changed to the exhaust port 213a side without separating the airflow flowing along the inner peripheral wall portion 733 from the inner peripheral wall portion 733 .

The outer peripheral wall portion 734 includes a first outer peripheral wall portion 734a extending upward from the counter-rotation side end portion 215b of the communication port 215 and an upper end of the first outer peripheral wall portion 734a extending upward in a cross section orthogonal to the rotation axis O. a second outer peripheral wall portion 734b, a third outer peripheral wall portion 734c that curves forward from the upper end of the second outer peripheral wall portion 734b, and a fourth outer peripheral wall portion 734d that extends forward from the front end of the third outer peripheral wall portion 734c. have.
The first outer peripheral wall portion 734a is inclined toward the inner peripheral wall portion 733 within a range of 0 to 3 degrees with respect to the vertical direction, and a boundary portion 734e between the first outer peripheral wall portion 734a and the second outer peripheral wall portion 734b. is located above the end portion of the inner peripheral wall portion 733 , that is, the rotation side end portion 215 a of the communication port 215 . The angle of inclination of the first outer peripheral wall portion 734a and the second outer peripheral wall portion 734b with respect to the vertical direction is the angle of the inner peripheral wall portion 733 (first flat portion 733a) with respect to the vertical direction (angle "B" in FIG. 9). ). At least one of the first outer peripheral wall portion 734a and the second outer peripheral wall portion 734b constitutes an inclined portion that approaches the exhaust port 213a as it separates vertically from the counter-rotation side end portion 215b of the communication port 215 .
The second outer peripheral wall portion 734b is inclined with respect to the vertical direction at an angle larger than the inclination angle of the first outer peripheral wall portion 734a. Here, the inclination is within the range of 8 to 15 degrees.
A boundary portion 734f between the third outer peripheral wall portion 734c and the fourth outer peripheral wall portion 734d is located at substantially the same position as the end portion of the inner peripheral wall portion 733 on the side of the communication port 215, or located forward of the end portion.
Thereby, air flows smoothly along the outer peripheral wall portion 734 .
