Description

Anti-overflow control method and device and cooking utensil Technical Field The present application relates to household electrical appliance technologies, and in particular, to an anti-overflow control method and apparatus, and a cooking appliance. Background At present, many precision control cookers are added with an anti-overflow detection function, one or more anti-overflow detection probes are arranged on the cooker wall or the cooker cover of the cookers to carry out anti-overflow detection, when foam or liquid in the cookers contacts the anti-overflow detection probes, an anti-overflow signal is generated, and therefore a micro control unit (Microcontroller Unit, MCU) stops heating for a period of time according to the anti-overflow signal control so as to prevent overflow. However, the method stops heating for a period of time after the overflow prevention signal is detected by the overflow prevention detection probe, so that the heating process is easily interrupted frequently due to misjudgment. Disclosure of Invention The application provides an anti-overflow control method, an anti-overflow control device and a cooking utensil, which avoid frequent interruption of a heating process caused by misjudgment of anti-overflow detection. In a first aspect, the present application provides an overflow prevention control method applied to a cooking appliance, the cooking appliance including a pot body and a pot cover, including: Detecting the state of the pot cover, wherein the state of the pot cover is an open state or a closed state; And when the state of the pot cover is detected to be an open state, controlling the cooking utensil to stop the overflow prevention detection. According to the anti-overflow detection method, by detecting the state of the pot cover, when the state of the pot cover is the open state, the anti-overflow detection is stopped, so that the anti-overflow erroneous judgment when the pot cover is opened is avoided, unnecessary anti-overflow detection is reduced, the frequent interruption of a cooking program is avoided, and the user experience is improved. In a possible implementation, the controlling the cooking appliance to stop the spill-proof detection includes: and if the cooking utensil is in a heat preservation or heating state before the state of the pot cover is detected to be in an open state, controlling the cooking utensil to stop the anti-overflow detection, and controlling the cooking utensil to keep the state before the pot cover is opened. In the pot cover open state, the co-worker stopping the anti-overflow detection maintains the cooking state of the cooking utensil, ensures the continuity of the cooking program, and avoids the influence of the pot cover open on the cooking effect. In a possible implementation, the controlling the cooking appliance to stop the spill-proof detection includes: and if the cooking utensil is in a heat preservation state before the state of the pot cover is detected to be in an open state, controlling the cooking utensil to stop the anti-overflow detection and controlling the cooking utensil to heat. Therefore, the temperature of food in the pot is prevented from being reduced due to the fact that the pot cover is opened, and the user experience is better. In a possible implementation, the controlling the cooking appliance to stop the spill-proof detection includes: And if the cooking utensil is in the heating stopping state after the overflow preventing detection before the state of the pot cover is detected to be the open state, controlling the cooking utensil to stop the overflow preventing detection and controlling the cooking utensil to resume the state before the heating stopping. By timely recovering the state of the cooking utensil, the influence on the cooking effect and the user experience caused by long-time heating stop is avoided. In a possible implementation, the controlling the cooking appliance to stop the spill-proof detection includes: And controlling the overflow preventing detection module of the cooking utensil to stop acquiring the overflow preventing detection data, or discarding the overflow preventing detection data sent by the overflow preventing detection module. In one possible implementation, the method further includes: And starting anti-overflow detection after detecting the preset time after the state of the pot cover is changed from the open state to the closed state, and/or when the state of the pot cover is the closed state and the temperature in the cooking utensil is greater than the preset temperature. Thereby avoiding unnecessary anti-overflow detection and reducing energy consumption. In a possible implementation manner, the cooking appliance is provided with a temperature measuring device, and the detecting the state of the pot cover includes: Collecting a temperature signal measured by the temperature measuring device; if the descending amount of the temperature signal in the preset time is l
