Abstract

The invention provides a direct current motor, a control method of the direct current motor and cooking utensil, and relates to the technical field of the cooking utensil. The direct current motor is used for being installed in an inner container of the cooking utensil. The direct current motor comprises a driving board including a VDC terminal for controlling the positive electrode of a power supply, a GND terminal for controlling a ground wire, an FG terminal for controlling a feedback signal and a PWM terminal for controlling the rotating speed and the rotating direction. According to the invention, technical problems of more control terminal interfaces, complex control, high cost and poor reliability of the direct current motor used by the cooking utensil with the heating fan are solved, the optimization of the driving program of the direct current motor on the cooking utensil is achieved, and the technical effects of reducing the cost of the direct current motor and improving the reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to a DC motor, a method for controlling the DC motor and cooking utensils. Background technique [0002] In recent years, sealed kitchen appliances for heating food, such as all-in-one steamers, ovens, and steamers, have gradually entered the public's field of vision. Most of them use heating fans to strengthen the heat convection in the kitchen appliance cavity to heat food. Specifically, the motor body is fixed outside the rear wall of the inner tank, and the shaft extends into the cavity through the opening of the inner tank to drive the fan blades to rotate. [0003] At present, most of the fan products used in kitchen utensils using heating fans are AC motors, which can only rotate in one direction and one speed, and cannot change the rotation speed and direction. Therefore, it is difficult to ensure the temperature uniformity in the cavity, which makes it difficult fo...
