Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Referring to fig. 1 to 3, a cooking appliance 100 according to an embodiment of the present invention will be described, and the cooking appliance 100 may be an air fryer.

As shown in fig. 1 and 2, a cooking appliance 100 according to an embodiment of the present invention includes: an appliance body 10, a vacuum device 20, a heating device 30 and a control device. The appliance body 10 defines a cooking space 101, the cooking space 101 is isolated from the external environment during cooking, food is placed in the cooking space 101 so as to be suitable for cooking food in the cooking space 101, it should be noted that the appliance body 10 may include a pot body 102 and a pot cover 103, an inner pot 104 is arranged in the pot body 102, the pot cover 103 is suitable for opening or closing an open end of the inner pot 104, the inner pot 104 defines the cooking space 101, and food is suitable for being placed in the inner pot 104 for cooking. The vacuum device 20 is used to vacuumize the cooking space 101 when the cooking space 101 is sealed to form a negative pressure in the cooking space 101. The heating device 30 serves to heat air to generate hot air, and the heating device 30 may input the hot air into the cooking space 101, and the hot air may bake food to be cooked. The control device is used for controlling the vacuum device 20 and the heating device 30, so that the cooking appliance 100 performs at least one vacuum cooking before performing the baking cooking or after completing the baking cooking, it should be noted that the cooking appliance 100 may perform at least one vacuum cooking before performing the baking cooking, the cooking appliance 100 may perform at least one vacuum cooking after completing the baking cooking, and may also perform at least one vacuum cooking before performing the baking cooking and after completing the baking cooking.

Specifically, the control device controls the vacuum device 20 and the heating device 30, so that the cooking apparatus 100 performs vacuum pickling cooking (i.e., a vacuum pickling stage), baking cooking (i.e., a baking stage) and vacuum degreasing cooking (i.e., a vacuum degreasing stage) in sequence, and it can also be understood that when the cooking apparatus 100 cooks food, the cooking apparatus 100 sequentially enters the vacuum pickling stage, the baking stage and the vacuum degreasing stage to cook food.

Wherein, when cooking utensil 100 cooks food, after the open end of pot 104 in cooking space 101 and pot cover 103 closed is put into to food, vacuum apparatus 20 makes cooking space 101 form the negative pressure to cooking space 101 evacuation, cooking utensil 100 is in vacuum pickling stage this moment, because food is easy to evaporate at the intracellular liquid under vacuum environment, can form the bubble in food inside, under the combined action of the pressure difference inside and outside the cell of food and capillary effect, inside food is more easily infiltrated in the outside liquid of food (soup), and, under vacuum condition, the food is whole can produce certain inflation, intercellular interval grow after the food inflation, be favorable to inside the soup infiltration food, make food go into the flavor more, thereby make the good food of cooking more fragrant, and then can promote the food taste.

In addition, after the cooking device 100 enters the baking stage from the vacuum curing stage, the heating device 30 inputs hot air into the cooking space 101, the hot air bakes the food to be cooked, fat in the food is changed into grease, and the grease has certain fluidity. After the baking stage is completed, the cooking appliance 100 enters a vacuum degreasing stage from the baking stage, the vacuum device 20 vacuumizes the cooking space 101 to enable negative pressure to be formed in the cooking space 101, the internal pressure of food is greater than the internal pressure of the cooking space 101 at the moment, grease with fluidity is extruded out of the food under the action of pressure difference, the degreasing effect of the food is achieved, and after the food is eaten by a user, the user is not easy to cause obesity, so that the body health of the user is facilitated.

Therefore, by arranging the vacuum device 20 which can vacuumize the cooking space 101 when the cooking space 101 is closed so as to form negative pressure in the cooking space 101 and the heating device 30 which heats air to generate hot air and inputs the hot air into the cooking space 101 so as to bake food to be cooked, the control device controls the vacuum device 20 and the heating device 30, the cooking appliance 100 can enter a vacuum pickling stage, a baking stage and a vacuum degreasing stage to cook, so that the cooking space 101 forms a vacuum negative pressure environment to pickle the food in the vacuum pickling stage, the food can be tasty, the cooked food is fragrant, the taste of the food can be improved, and then the food is baked at high temperature in the baking stage, so that the fat in the food becomes grease with certain fluidity, and finally, in the vacuum degreasing stage, grease with fluidity in the food is effectively extruded in a vacuum negative pressure environment, so that degreasing is realized, the degreasing effect of the food can be improved, and the vacuum degreasing device is beneficial to the body health of a user.

From this, through utensil body 10, vacuum apparatus 20, heating device 30 and controlling means cooperation, compare with prior art, can make food tasty more, thereby make the food of culinary art more fragrant, and then can promote food taste, in the stage of toasting, through carrying out high temperature baking to food, make the inside fat of food become the grease that has certain mobility, at last in the vacuum degreasing stage, realize the degreasing, can improve the effect that food degreased, be favorable to user's health, accord with the healthy diet theory of low oil low fat.

In some embodiments of the present invention, the vacuum device 20 and the heating device 30 are integrated, so that the vacuum device 20 and the heating device 30 can be prevented from being separately produced, the production cost of the cooking appliance 100 can be reduced, and the overall occupied space of the vacuum device 20 and the heating device 30 can also be reduced.
