Abstract
A motor holder or a lower case defines therein a circuit accommodating chamber for accommodating a control circuit device. A side wall of the motor holder or the lower case that defines the circuit accommodating chamber has a vent for ventilating the chamber. A boundary section is formed between the motor holder and the lower case. An overhang extends from the motor holder. In a section of the circumference of the lower case, the overhang continuously covers the boundary section along the outer surface of the side wall of the lower case. A bulging portion is arranged to prevent water droplets from reaching the vent from the overhang. Therefore, the motor assembly prevents the integrally assembled control circuit device from being wet.
Claims13
A motor assembly for a vehicle air conditioner, comprising:
- a motor having a rotary shaft;
- a control circuit device that controls the motor to rotate;
- a fan fixed to the rotary shaft;
- a motor holder for accommodating the motor;
- a lower case attached to the motor holder, wherein the motor holder or the lower case defines therein a circuit accommodating chamber for accommodating the control circuit device, a side wall of the motor holder or the lower case that defines the circuit accommodating chamber has a vent for ventilating the circuit accommodating chamber, a boundary section being formed between the motor holder and the lower case;
- an overhang that extends from the motor holder, the overhang being integrally formed with the motor holder, wherein the overhang faces an outer surface of the side wall of the lower case, and wherein, in a section of the circumference of the lower case, the overhang continuously covers the boundary section along the outer surface of the side wall of the lower case;
- and
- a bulging portion that projects from the overhang in a direction away from the motor holder, wherein the bulging portion is arranged to prevent water droplets from reaching the vent from the overhang.
A motor assembly for a vehicle air conditioner, comprising:
- a motor having a rotary shaft;
- a control circuit device that controls the motor to rotate;
- a fan fixed to the rotary shaft, wherein, when rotates, the fan draws air outside or inside the vehicle and sends the air into the passenger compartment;
- a motor holder for accommodating the motor;
- a lower case attached to the motor holder, wherein the motor holder or the lower case defines therein a circuit accommodating chamber for accommodating the control circuit device, a side wall of the motor holder or the lower case that defines the circuit accommodating chamber has a vent for ventilating the circuit accommodating chamber, a boundary section being formed between the motor holder and the lower case;
- an overhang that is extended from the motor holder, the overhang being integrally formed with the motor holder, wherein the overhang faces an outer surface of the side wall of the lower case, and wherein, in a section of the circumference of the lower case, the overhang continuously covers the boundary section along the outer surface of the side wall of the lower case;
- a bulging portion that projects from the overhang in a direction away from the motor holder, wherein the bulging portion is arranged to prevent water droplets from reaching the vent from the overhang;
- a motor terminal extending from the motor;
- and
- a connecting member for electrically connecting the motor terminal with the control circuit device, the motor terminal and the connecting member forming an electric path from the motor to the control circuit device, wherein an upward extension is provided in part of the connecting member in the electrical path that is close to the control circuit device, the upward extension extending upward with respect to a direction from the motor toward the control circuit device along the electric path.
