(1) Consider the weight of the items to be handled

On the basis of the above-mentioned sealed drawer, in the technical solutions disclosed in the embodiments of the present application, a pretreatment method for preprocessing storage items in the sealed drawer is also disclosed. After being put into the sealed drawer, the refrigerator may pre-process the put-in items based on a predetermined program. Specifically, see FIG. 7 , and the pre-processing method is as follows.

Step S101: Acquire weight data, where the weight data is estimated weight data of items put into the sealed drawer by a user;

The user can input the weight data through the control panel of the refrigerator, or input the weight data remotely through the target terminal. as the weight data.

Step S102: obtaining the user menu and the reservation duration input by the user;

The user can input the user menu and the reservation time remotely through the control panel of the refrigerator or through the target terminal.

Step S103: Obtain a processing strategy that matches the user menu, and calculate the processing time of each processing stage in the processing strategy based on the weight data entered by the user and the processing time relationship function that matches the user menu. User menu ;

In this solution, different processing strategies in the sealed drawer are configured based on different user menus;

For example, the user menu may be frozen fruit, pre-order thawing, peeling assistant, delicious ice cream, crispy biscuits, fried rice, onion mate, bitter gourd, etc. Each user menu corresponds to an independent processing strategy. The controller manages the temperature and humidity within the sealed drawer based on the treatment strategy.

And keep the duration of T2, after the duration of T2, stop heating the sealed drawer, and then output a reminder to the user when the appointment time T1 comes.

Referring to Figure 8-3, taking the peeling assistant as an example, the temperature adjustment process in the sealed drawer is described:

The weight of the processed ingredients put into the sealed drawer is Mkg. Assuming that the user's reservation time is T1, the system calculates the thawing time T2 required for Mkg of ingredients. In the case where the thawed item is kiwi fruit or tomato as an example, the freezing time can be T2=(100+0.5*M)h, rewarming time T3=(550+100*M)min, after the user puts the processed ingredients into the airtight drawer, the airtight drawer is cooled to make the inside of the airtight drawer The ambient temperature reaches the target temperature (for example, -18°C) and lasts for a period of T2. Then, the cooling of the airtight drawer is stopped, the heating device is turned on, and the temperature in the airtight drawer is raised to the calibration temperature (for example, 5 ℃), and keep it for T3 time, then turn off the heating device, and output a prompt message to the user when the appointment time comes.

Referring to Figure 8-4, taking delicious ice cream as an example, the temperature adjustment process in the sealed drawer is described:

The weight of the ice cream put into the sealed drawer is Mkg. Assuming that the user's reservation time is T1, the processing time required by the system to calculate Mkg ice cream is T2, T2=(90+100*M)min, at time T1-T2 Before the arrival, the sealed drawer is controlled to be in a refrigerated state, and its internal ambient temperature can be -10°C. When the time T1-T2 arrives, the sealed drawer exits the refrigeration state, and the heating device is controlled to turn on, and the sealed drawer is controlled by the heating device. The temperature inside reaches the processing temperature of ice cream, and maintains the T2 time. When the T2 time comes, the heating device is turned off. When the appointment time arrives, a reminder is output to the user. Of course, in the technical solution disclosed in another embodiment of the present application, after the processing instruction is obtained, the heating device can also be controlled to be turned on immediately, and the temperature in the sealed drawer can be controlled by the heating device to reach the processing temperature of ice cream, and keep T2 After the duration of T2, the heating of the sealed drawer is stopped, and then when the preset time T1 comes, a reminder is output to the user.

For another example, when the user's menu is crispy biscuits, the weight of the biscuits placed in the sealed drawer is Mkg.
