Technical Field

The invention belongs to the technical field of food heat preservation, and particularly relates to an electric heating heat preservation rice bucket controlled by a microcomputer.

Background

The heat preservation rice bucket is heat preservation equipment which heats water at the bottom in the rice bucket by adjusting the temperature through a rotating temperature regulator at the bottom of an operation table as shown in figure 1, so that the rice bucket is filled with constant-temperature water vapor to achieve constant temperature in the rice bucket and preserve heat of rice and dishes in the rice bucket. The traditional temperature control device of the electric heating heat-preservation rice bucket consists of a working power supply indicator lamp, a rotary temperature regulator and a master control switch. The equipment during operation connects the power, opens total accuse switch, and work power indicator lamp is bright, then adjusts rotatory temperature regulator, manual regulation temperature. Because the temperature control is completely manually operated and is judged by the experience of workers, the temperature control is inaccurate. Because of unnecessary safety alarm measures, the water is not added in time, the water shortage inside the water tank is easy to cause dry heating, the due use purpose cannot be achieved, and simultaneously, the resource waste and the safety performance reduction are caused by the dry heating. The bottom of the barrel body is provided with a water control valve to control the discharge of waste water after use, and the control valve at the bottom of the barrel body needs to be extended during operation, so that the operation is inconvenient.
