Abstract

The invention discloses a cooking utensil and a heat preservation control method and a heat preservation control device.The method comprises the following steps that when it is detected and recognized that the cooking utensil enters a heat preservation stage, a heating device of the cooking utensil is controlled to stop heating work or reduce heating power; detecting the temperature in a cooking cavity of the cooking utensil; when it is determined that the temperature in the cooking cavity is reduced to a first temperature threshold value, a vacuum device of the cooking utensil is controlled to vacuumize the cooking cavity, the first temperature threshold value is larger than a preset target heat preservation temperature, and therefore the interior of the cooking utensil is in a negative pressure state for a long time, food is effectively prevented from being sour or deteriorated due to heat preservation, and the cooking utensil is more attractive in appearance. In addition, vacuumizing is carried out before the temperature in the cooking cavity is reduced to the target heat preservation temperature, and when the heat preservation temperature is reached, due to the fact that the temperature in the cooking cavity is reduced, the vacuum degree can be further enhanced.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, and in particular to a heat preservation control method for a cooking appliance, a heat preservation control device for a cooking appliance, and a cooking appliance. Background technique [0002] Cooking appliances such as electric rice cookers in the related art sometimes need to keep food warm, and the heat preservation time may be longer. However, when the rice cooker is kept warm, bacteria are easy to breed due to poor sealing, which causes the problem of sour or smelly food after a long time of keeping the food warm. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. For this reason, an object of the present invention is to propose a heat preservation control method for cooking utensils. By vacuuming, the inside of the cooker is in a negative pressure state for...
