  "textContent": "A heating apparatus includes: a motor control unit, having an inverter and a controller that are connected to each other; an electric heater; and a motor, having three-phase windings, where ends of the three-phase windings are connected to the inverter, the other ends of the three-phase windings are connected to a connection point, and the connection point is connected to the electric heater. Therefore, the other ends of the three-phase windings in the motor can be connected to the connection point to form three-phase windings of a Y connection, the electric heater is connected to the connection point, and the motor control unit can control currents in the three-phase windings in the motor to control the motor to rotate and emit heat, and can further control the currents in the three-phase windings to control a current flowing through the electric heater through the connection point, to control the electric heater to emit heat. Therefore, the electric heater can be controlled by using the motor control unit that controls the motor, without a need to independently dispose a control circuit for controlling the electric heater, so that a quantity of controllers, a weight of the heating apparatus, a required occupation space of the heating apparatus, and costs of the heating apparatus can be reduced.",
