- the blown air and moisture are likely to enter the inner circumferential space of the rib in a low pressure region where the flow rate of the blown air in the scroll chamber is high. Therefore, when the notch is formed in the low pressure region in the scroll chamber as in the conventional blower, the blown air and moisture easily enter the inner peripheral space of the motor side rib from the scroll chamber through the notch. Thus, the moisture that has entered the inner circumferential space of the motor-side rib is not easily discharged into the scroll chamber through the notch.
- a blower includes an electric motor, a plurality of blades arranged around the rotation axis of the electric motor, and a plurality of blades connected to each other and a rotational drive generated by the electric motor.
- the motor casing is disposed on a surface facing the main plate, and includes a motor-side rib that is annularly formed along the circumferential direction of the fan and protrudes toward the main plate.

- the main plate 22 has a substantially conical shape that is convex toward one end in the direction of the rotation axis, that is, toward the suction port 45.
- the main plate 22 is coupled to the rotating shaft 11 at the center thereof, and transmits the rotational driving force generated by the electric motor 1 to the blade 21.
- the fan 2 is rotationally driven by the electric motor 1 so that air is sucked into the fan 2 from one end side in the rotation axis direction, and the sucked air is blown out toward the outside in the fan radial direction. ing.
- the motor casing 3 includes a first motor casing 31 and a second motor casing 32.
- the motor casing 3 forms therein a cooling air introduction passage 33 that guides a part of the blown air to the inside of the electric motor 1 as electric motor cooling air.
- a cooling air discharge passage 34 is formed between the first motor casing 31 and the main plate 22 for returning the motor cooling air after passing through the interior of the motor 1 to the scroll chamber 43 described later.
- the scroll casing 4 includes a first scroll casing 41 and a second scroll casing 42.
- the scroll casing 4 forms a spiral scroll chamber 43 on the outer periphery of the fan 2.
- the scroll chamber 43 has a flow passage cross-sectional area that gradually increases from the winding start portion of the scroll chamber 43, that is, from the nose portion 44 to the winding end portion, so that the air blown from the fan 2 is efficiently gathered and flows downstream. Yes.
- An arrow A in FIG. 2 indicates an air flow in the scroll chamber 43.
- the first scroll casing 41 is formed with an inlet 45, which is an inlet of air sucked by the fan 2, on one end side in the rotation axis direction.
- a through hole 46 into which the first motor casing 31 is fitted is formed at a position facing the suction port 45.
- the motor-side rib 35 is formed with a first notch portion 35a and a second notch portion 35b that allow the inner space and the outer space of the motor-side rib 35 to communicate with each other.
- the second cutout portion 35b is disposed in the low pressure region that is outside the high pressure region B, and more specifically, is displaced by about 180 ° in the fan circumferential direction with respect to the first cutout portion 35a.
- an inside / outside air switching box is connected upstream of the air blower and an air conditioning unit is connected downstream of the air blower.
- an evaporator for cooling the blown air a heater core for heating the blown air, a mode door for setting the blow destination of the blown air, and the like are disposed. Then, the air sucked by the fan 2 is sent to the air conditioning unit through the scroll chamber 43, passes through the air conditioning unit, and is blown toward the air outlets on the most downstream side of the air flow.
- the flow velocity of the blown air in the scroll chamber 43 gradually increases from the winding start portion to the winding end portion. That is, the flow rate of the blown air in the scroll chamber 43 is low in the high pressure region B where the first notch 35a is disposed, and is high in the low pressure region where the second notch 35b is disposed.
- the moisture that has entered the inner circumferential space of the motor-side rib 35 is discharged into the scroll chamber 43, so that corrosion of the components of the motor 1 due to the intruded moisture can be prevented.
- the electric motor side second rib 36 protrudes toward the cooling air discharge passage 34 and is formed on a surface facing the main plate 22.
- the motor-side second rib 36 extends in the rotation axis direction and is formed in an annular shape along the fan circumferential direction.
- the motor-side second rib 36 is formed with an outer first notch 36a and an outer second notch 36b that connect the inner space and the outer space of the motor-side second rib 36.
- the outer first cutout portion 36a is disposed on the upstream side of the air flow A with respect to the first cutout portion 35a. More specifically, the outer first cutout portion 36a is disposed within a range of about 90 ° in the fan circumferential direction with respect to the first cutout portion 35a.
- the outer second cutout portion 36b is arranged on the downstream side of the air flow A with respect to the first cutout portion 35a. More specifically, the outer second notch 36b is disposed within a range of about 90 ° in the fan circumferential direction with respect to the first notch 35a.
- At least the outer second notch portion 36 b is disposed at a portion facing the high pressure region B in the scroll chamber 43.
- the outer second notch 36 b is arranged at a portion facing the high pressure region B in the scroll chamber 43, the moisture that has entered the inner circumferential space of the second rib 36 on the motor side is retained in the scroll chamber 43.
- the air blows into the inner circumferential space of the electric motor-side second rib 36 from the low-pressure region and is pushed toward the outer second notch 36b, and is discharged from the outer second notch 36b to the scroll chamber 43.
- a part of the water that has entered the inner peripheral space of the motor-side second rib 36 gets over the motor-side rib 35 and enters the inner peripheral space of the motor-side rib 35. Furthermore, a part of the water enters the inner circumferential side space of the electric motor side rib 35 through the second cutout portion 35b in the low pressure region.
- the moisture that has entered the inner circumferential space of the motor-side rib 35 is pushed toward the first notch 35 a by the blown air that enters the inner circumferential space of the motor-side rib 35 from the low pressure region in the scroll chamber 43. Then, the moisture discharged from the first cutout portion 35a to the inner peripheral space of the electric motor side second rib 36 and further discharged into the inner peripheral space of the electric motor side second rib 36 is the electric motor side second rib 36.
