Problems solved by technology

However, the electric heating cooker with this structure has the following defects: Due to technical and space reasons, the electrical connectors of the electric heating cooker currently on the market are only 5-core connectors at most. The circuit of the device can only process the water temperature; once the food in the pot overflows, it cannot be controlled because there is no corresponding overflow detection link, which brings a lot of inconvenience to consumers

Abstract

An electric heating cooker provided with an overflow prevention structure and a method for judging overflow, relating to the electric heating cooker, in particular to the overflow prevention structure and the overflow prevention method of the electric heating cooker. An electric heating pot with an anti-overflow structure, including a pot body and a wire base. The body is equipped with a heating plate and a temperature sensor, and the wire base is equipped with a power supply and a controller. The pot body and the wire base are electrically connected through a 5-pin electrical connector. ; An anti-overflow detection device is installed on the body of the pot, and the anti-overflow detection device includes an upper probe and a lower probe, the upper probe is set on the upper part of the pot body cavity, and the lower probe is set on the lower part of the cavity or on the heating plate; 5 Core electrical connector, 3 cores are connected to the L pole, N pole, and E grounding pole of the power supply, the other 2 cores are connected to the temperature sensor, upper probe, and lower probe, and one end of the 2 cores is connected to the controller . The invention can realize the detection and control of the water temperature and overflow of the electric heating pot at the same time, has the advantages of practicality, convenient use, low cost, reliable control, etc., and effectively improves the market competitiveness of the electric heating pot.

Description

technical field [0001] The invention relates to an electric heating pot, in particular to an anti-overflow structure and method of the electric heating pot. Background technique [0002] Some existing electric heating cookers, because the cooker body needs to be frequently taken and placed, the way of separating the cooker body from the power cord base is often used in structure, that is, the cooker body and the power cord base are frequently separated and connected, and the power cord base is equipped with a lower The upper connector is installed on the body of the connector and the pot. Electrical and control connections are made through upper and lower connectors. Restricted by the internal space of the pot and the high ambient temperature, it is difficult to assemble the electronic control part inside the pot. So install the control circuit on the power cord holder. For this reason, when it is necessary to transmit the detected water temperature information on the pot...
