Cooking utensil, control method and device thereof

Abstract

The invention discloses a cooking utensil, a control method and device thereof. The cooking utensil comprises a pressure limiting valve used for blocking an exhaust port, and the corresponding pressure of the pressure limiting valve in a first state is larger than the corresponding pressure of the pressure limiting valve in a second state. The method comprises the steps that whether the position where the cooking utensil is located is a plateau area or not is determined; if that the position is determined to be the plateau area, the cooking utensil is controlled to carry out cooking operation through the first control temperature and the pressure limiting valve in the first state, or the cooking utensil is controlled to carry out cooking operation through the second control temperature and the pressure limiting valve in the second state, and the first control temperature is larger than the second control temperature; and when the temperature in the pot of the cooking utensil reaches the first control temperature or the second control temperature, the cooking utensil is controlled to be switched from the first cooking stage to the second cooking stage. The technical problem that food overflows in the low-pressure cooking operation process of a cooking utensil in the plateau area in the prior art is solved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a cooking appliance and a control method and device thereof. Background technique [0002] At present, the double-valve electric pressure cooker can achieve the effect of continuous exhaust boiling at low pressure and high pressure after the upper pressure through the inner valve and outer valve that are nested together. Among them, the boiling through low-pressure exhaust can make the rice grains clear and fragrant, which is widely used. Consumer acceptance and use. Regardless of whether the double-valve electric pressure cooker is used in plateau areas or plain areas, the control method of low-pressure exhaust gas boiling is the same, but because the boiling point in plateau areas is lower than that in plain areas, the target temperature in the control method cannot be reached, resulting in constant heating, thus There will be problems such as food overflow and pressure lim...

AI Technical Summary

Problems solved by technology

Regardless of whether the double-valve electric pressure cooker is used in plateau areas or plain areas, the control method of low-pressure exhaust gas boiling is the same, but because the boiling point in plateau areas is lower than that in plain areas, the target temperature in the control method cannot be reached, resulting in constant heating, thus There will be problems such as food overflow, pressure limiting valve overturning, etc.

[0003] For example, the boiling point of the plateau area is 90°C, and the boiling point of the software in the double-valve electric pressure cooker is uniformly set to 100°C. When using a light valve of 30kPa to work, the temperature of the double-valve electric pressure cooker can only reach 96°C, and cannot reach the target temperature of 106°C At this time, the double-valve electric pressure cooker will continue to heat, causing food to overflow, and the pressure-limiting valve to overturn

[0004] For the above problems, no effective solution has been proposed
