4. With respect to control strategies

(1) Taking into account the weight of the articles to be treated

On the basis of the sealed drawer, in the technical scheme disclosed in the embodiment of the present application, a pretreatment method for pretreating stored articles in the sealed drawer is further disclosed, and after a user puts articles to be pretreated into the sealed drawer, a refrigerator can pretreat the put articles based on a predetermined program, specifically, referring to fig. 7, the pretreatment method is as follows.

Step S101: obtaining weight data, wherein the weight data is estimated weight data of an article placed in the sealed drawer by a user;

the user can input the weight data through a control panel of the refrigerator or remotely input the weight data through the target terminal, and of course, when a weight sensor is arranged in the sealed drawer, the measurement data of the weight sensor can be used as the weight data.

Step S102: acquiring a user menu and a reserved time length input by a user;

the user can enter the user menu and the reserved time length remotely through a control panel of the refrigerator or through the target terminal.

Step S103: acquiring a processing strategy matched with the user menu, and calculating to obtain a processing time user menu of each processing stage in the processing strategy based on the weight data input by the user and a processing time relation function matched with the user menu;

in the scheme, different processing strategies in the sealed drawer are configured based on different user menus;

for example, the user menus may be frozen fruits, scheduled thawing, peeling assistants, delicious ice cream, crisp biscuits, fried rice grains, onion mates, bitter gourds and the like, each user menu corresponds to an independent processing strategy, and the controller manages the temperature and humidity in the sealed drawer based on the processing strategies.

In the technical solution disclosed in the embodiment of the present application, the duration of each stage in the processing strategy may be adjusted based on the weight data, and then the controller manages the temperature and humidity inside the sealed drawer according to the adjusted duration of each stage.

In addition to the user menu, the user menu may include a scheduled fermentation, a breast milk heating, a hot dish, a high-quality yogurt, and the like. When the user menu is reserved fermentation, cosmetic preservation, breast milk heating, hot dishes or high-quality yoghourt, the controller can directly invoke a control strategy matched with the reserved fermentation, the cosmetic preservation, the breast milk heating, the hot dishes or the high-quality yoghourt, and dynamically adjust the environmental temperature and the environmental humidity in the sealed drawer based on the target temperature, the target humidity and the processing time of each stage in the control strategy.

Step S104: sequentially processing the environmental temperature in the sealed drawer based on the target temperature corresponding to each processing stage in the processing strategy, and keeping the processing time length matched with each processing stage;

step S105: and when the reserved time length comes, outputting prompt information to the user.

In a technical solution disclosed in another embodiment of the present application, before the temperature in the sealed drawer is adjusted based on the processing policy, the processing policy and the duration of each stage in the processing policy may be displayed to a user, after a confirmation instruction input by the user is obtained, the temperature and the humidity in the sealed drawer are adjusted based on the processing policy and the duration of each stage in the processing policy, when an adjustment instruction input by the user is obtained, the processing policy or the duration of each stage is adjusted based on the adjustment instruction, and after the adjustment is completed, if the confirmation instruction input by the user is obtained, the temperature and the humidity in the sealed drawer are adjusted.

In this scheme, each processing strategy can be divided into N processing stages, where N is a positive integer, each stage corresponds to a target temperature, and the weight of an article to be preprocessed in the preprocessing time of each stage is in a positive correlation, so that the preprocessing time of each stage can be calculated based on the weight data, and the sum of the preprocessing time of each stage is used as the minimum preprocessing time. When the appointment time input by the user is empty, the system automatically displays the shortest processing time to the user through a control panel or a target terminal, and defaults the shortest processing time as the preprocessing time required by the user.
