Abstract
A blower including a duct configured to allow air to flow in and out and a plurality of blades disposed to be parallel to the duct. Each of the blades including a first part, a second part, and an airflow generator configured to generate airflow in a direction from the inlet to the outlet by applying a voltage between the first electrode and the second electrode which are disposed between a first electrode on a side of the inlet, a second electrode on a side of the outlet, and a dielectric. In a cross section of the blade in the airflow direction when cut in a cross section perpendicular to each of the blades, the first part has a thickness decreasing in a direction toward the inlet and the second part has a thickness decreasing in a direction toward the outlet.
Claims20
An air conditioner comprising:
- a heat exchanger;
- and
- a blower configured to blow air to exchange heat through the heat exchanger, the blower including:
- a duct including an inlet and an outlet, and
- a plurality of blades arranged in the duct, the plurality of blades spaced a regular distance from each other in a vertical direction, each of the plurality of blades including:
- a first part having a thickness decreasing in a direction toward the inlet,
- a second part having a thickness decreasing in a direction toward the outlet, and
- a third part formed between the first part and the second part, third part including an airflow generator,
- wherein the airflow generator includes:
- a first electrode,
- a second electrode, and
- a dielectric,
- wherein the airflow generator generates airflow in a direction from the inlet to the outlet when a voltage is applied between the first electrode and the second electrode.
