However, as the season changes, the external temperature will also change. When the external ambient temperature changes greatly, it will affect the change of the vacuum degree in the pot, and the vacuum degree will be inaccurate, which will affect the preservation effect.
For example, the temperature is relatively high in summer, if you still use ordinary vacuum for freshness preservation, the freshness preservation effect will not be achieved

The invention discloses a cooking appliance and a vacuum reservation fresh-keeping control method thereof. The cooking appliance comprises a pot body, wherein the pot body is provided with a cooking cavity with an open top; a cover body, wherein the cover body is movably arranged on the pot body, between the closed position and the open position, and the cover body is provided with an air extraction port and an air exhaust port; a vacuum device, wherein the vacuum device is arranged in the cover body and is respectively communicated with the air extraction port and the air exhaust port, and the vacuum device is used for vacuuming the cooking cavity so as to form negative pressure vacuum in the cooking cavity; a temperature detection device, wherein the temperature detection device is usedfor detecting the ambient temperature; a control device, wherein the control device is used for acquiring the vacuum degree when the cooking appliance reserves fresh keeping according to the ambient temperature when the cooking appliance receives a vacuum reservation fresh-keeping instruction, controlling the vacuum device to work at a first preset rotating speed according to the acquired vacuum degree, and controlling the vacuum device to stop working until the vacuum degree in the cooking cavity reaches an acquired vacuum degree so as to ensure the vacuum fresh keeping effect.
Description
technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a cooking appliance and a control method for vacuum reservation fresh keeping of the cooking appliance. Background technique [0002] At present, some cooking utensils (such as electric rice cookers) have a vacuum pre-preservation function, which is used by users throughout the year. [0003] In related technologies, no matter how the external environment changes, the same degree of vacuum is used, such as figure 1 shown. However, as the season changes, the external temperature will also change. When the external ambient temperature changes greatly, it will affect the change of the vacuum degree in the pot, and the vacuum degree will be inaccurate, which will affect the preservation effect. For example, the temperature is relatively high in summer, if you still use ordinary vacuum for freshness preservation, the freshness preservation effect will not be achieved. C...
