Detailed ways

The present invention is described below based on examples, but the present invention is not limited to these examples. In order to avoid obscuring the essence of the present invention, well-known methods, processes, procedures, and elements have not been described in detail.

In addition, those of ordinary skill in the art should understand that the drawings provided herein are for the purpose of illustration, and the drawings are not necessarily drawn to scale.

Unless the context clearly requires otherwise, the words "including", "comprising" and the like throughout the specification and claims should be interpreted as inclusive rather than exclusive or exhaustive; that is, "including but not limited to" Meaning.

In the description of the present invention, it should be understood that the terms “first”, “second”, and the like are used for descriptive purposes only, and cannot be understood to indicate or imply relative importance. In addition, in the description of the present invention, unless otherwise stated, "a plurality" means two or more.

Aiming at the problems of low nutrient content and poor flavor of the soup produced by the existing soup cooking method of cooking appliances, the reason is that in the existing soup control method, the soup is heated to the maximum with boiling power in the early stage, so that the soup is in the early stage. If the temperature rises too quickly, the protein, amino acids, nucleosides and other nutrients in the food material will rapidly deform and solidify, and cannot be fully dissolved in the soup. As a result, the soup produced by the existing soup method has low nutrient content and poor flavor. problem.

In view of the above problems, one embodiment of the present invention provides a cooking appliance and a control method thereof. The cooking appliance may be an appliance such as a micro-pressure cooker, a rice cooker, an electric pressure cooker, an electric steamer, etc., which can effectively boil the liquid in the pot to achieve the cooking function. The control method is:

The control process before the internal liquid of the cooking appliance is boiled includes at least one heating and maintaining stage. In the heating and maintaining stage, the internal temperature of the cooking appliance is heated to a predetermined temperature interval, and the internal temperature is controlled to be maintained at the predetermined temperature for a predetermined time. In the interval, obviously, since the control process before the internal liquid boiling of the cooking appliance includes at least one heating and maintaining stage, the highest temperature in the predetermined temperature interval is lower than the liquid boiling temperature, and at least one heating and maintaining stage can make more Numerous nutrients such as proteins, peptides, amino acids, and nucleosides are dissolved in the soup, so that the soup produced is richer in nutrition and better in flavor.

In an optional embodiment, a plurality of heating and maintaining stages are sequentially arranged in chronological order, so that the internal temperature of the cooking appliance can be maintained in multiple temperature intervals, so as to be suitable for different nutrients such as proteins, peptides, amino acids, and nucleosides. Dissolution of substances. The highest value of the predetermined temperature interval corresponding to the heating and maintenance phase operated first is lower than the lowest value of the predetermined temperature interval corresponding to the heating and maintenance phase operated later. That is, during the sequential operation of multiple heating and maintaining stages, the entire area of the internal temperature of the cooking appliance rises. For example, the multiple heating and maintaining stages include a first heating and maintaining stage and a second running in chronological order. The heating and maintaining phase, wherein the predetermined temperature interval corresponding to the first heating and maintaining phase is [T1, T2], and the predetermined temperature interval corresponding to the second heating and maintaining phase is [T3, T4].

The range of the first temperature value T1 is 35 to 45 ° C, and the range of the second temperature value T2 is 40 to 50 ° C, T2> T1.

The third temperature value T3 ranges from 55 to 60 ° C, the fourth temperature value T4 ranges from 60 to 65 ° C, and T4> T3.
