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 in 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 the technical scheme disclosed in another embodiment of the present application, before the temperature in the sealed drawer is adjusted based on the processing strategy, the duration of each stage in the processing strategy and the processing strategy can be displayed to the user, after the confirmation instruction input by the user is obtained, the temperature and the humidity in the sealed drawer are adjusted based on the duration of each stage in the processing strategy and the processing strategy, when the adjustment instruction input by the user is obtained, the duration of the processing strategy or 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 again.
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. And when the appointed 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 to be the preprocessing time required by the user.
Referring to fig. 8-1, the process of temperature regulation inside the sealed drawer will be described, taking frozen fruit as an example:
the user reservation time is T1, the weight of fruits put into the sealed drawer is Mkg, in the first stage of a processing strategy, the temperature in the sealed drawer is adjusted and kept at-18 ℃, the time consumption time of the first stage is about T2 ═ 24+ M (h), then the second stage is a rewarming stage, in the second stage, the main heating equipment is started to heat the environment temperature in the sealed equipment to 0 ℃, and the time consumption time of the second stage is about T3 ═ 550+ 100M (M) min; and when the temperature in the sealed drawer reaches 0 ℃, closing the heater, keeping the temperature in the sealed drawer at 0 ℃, and reminding the user to take the articles when the scheduled time comes, wherein the sum of the T2 and the T3 is recorded as the minimum time of the pretreatment, and when the scheduled time T1 is less than the sum of the T2 and the T3, reminding the user that the scheduled time is too short to finish.
Referring to fig. 8-2, the temperature regulation process in the sealed drawer will be described by taking a scheduled thawing as an example:
the weight of the unfrozen food material put into the sealed drawer is Mkg, the reservation time of a user is T1, and the system calculates Mkg the unfreezing time period T2 needed by the food material, wherein taking the unfrozen food as meat as an example, the unfrozen time period can be T2 ═ 100+200 × M) min, the sealed drawer is controlled to be in a cold storage state before the time T1-T2 comes, the internal environment temperature can be-5 ℃, when the time T1-T2 comes, the sealed drawer exits from the cold storage state, the heating device is controlled to be started, the temperature in the sealed drawer is controlled to reach the unfreezing temperature corresponding to the food material through the heating device, the time T2 is kept, and when the reservation time comes, a prompt is output to the user. Certainly, in the technical solution disclosed in another embodiment of the present application, after the reserved thawing instruction is obtained, the heating device may also be controlled to be turned on immediately, the heating device controls the temperature in the sealed drawer to reach the thawing temperature corresponding to the food material, and the time duration of T2 is kept, after the time duration of T2, the sealed drawer is stopped being heated, and then when the reserved time T1 comes, a reminder is output to the user.
Referring to fig. 8-3, a peeling assistant is taken as an example to explain the temperature adjusting process in the sealed drawer:

And refrigerating the stored articles in the sealed drawer to enable the ambient temperature in the sealed drawer to reach a target temperature matched with the processing stage.
When a certain processing stage requires to wet the inside of the sealed drawer, the control unit 800 is specifically configured to:
the air door of the sealed drawer is opened through an air door driver, air is introduced into the sealed drawer through an air supply opening, and the air is sent out of the sealed drawer through an air return opening;
and when the environment humidity detected by the humidity sensor reaches the target humidity corresponding to the processing stage, closing the air door of the sealed drawer through the air door driver.
The regulating unit 800 is further configured to record the ambient temperature in the sealed drawer before opening the damper of the sealed drawer, and control the main heating device to be turned on after the damper of the sealed drawer is closed by the damper driver, so that the ambient temperature in the sealed drawer is restored to the ambient temperature before opening the damper of the sealed drawer.
Corresponding to the above method embodiment, the regulating unit 800 is specifically configured to:
when the sealed drawer needs to be controlled to cool, the air supply opening can be connected to the evaporator, cold air is directly introduced into the sealed drawer through the evaporator, and the cooling speed of the sealed drawer can be adjusted by adjusting the working frequency of the refrigerator compressor.
Corresponding to the above method embodiment, the regulating unit 800 is specifically configured to:
when the humidity in the sealed drawer needs to be adjusted, generally speaking, the situation of overlarge humidity can occur in the refrigerator, at the moment, the air door can be opened, air flows into the sealed drawer through the air supply opening, then the air return opening flows out of the sealed drawer, and the excess moisture in the sealed drawer is taken away through the flowing air, so that the humidity adjustment in the sealed drawer is reduced.
