Abstract
The invention relates to a rice cooker and an energy-saving control method. The rice cooker comprises a control unit arranged on a body, a heating body for heat or heat preservation under the control of the control unit and a cooker cover included in the body, and further comprises a position detection device for detecting the position of the cooker cover and transmitting acquired signals to the control unit. The energy-saving control method of the energy-saving rice cooker comprises the following steps: 1, detecting the opening state of the cooker cover of the ice cooker; and 2, controlling the ice cooker to stop work when the cooker cover of the ice cooker is under the opening state. When the rice cooker is under the state of non-heat preserving state such as cooking, heating and standby operation, the control unit closes the position detection device by driving signals so that the position detection device is ineffective. Accordingly, the position detection device operates normally only under the heat preserving state without additional redundant energy consumption for operation out of the heat preserving state, thereby achieving the aim of further improving energy-saving effect.
