The embodiment of the invention provides a food self-adaptive refrigeration method for a temperature-variable chamber, and the embodiment explains the methods in the first, second and third embodiments in more detail by disclosing more technical details.
Specifically, in this embodiment, in order to realize the self-adaptation of the refrigerating temperature, two sensors need to be configured in the temperature-changing chamber of the refrigerator: a temperature sensor: for measuring the temperature of the food in the temperature changing chamber; a weight sensor: for measuring the weight of the food in the temperature changing chamber.
In this embodiment, a cloud platform is taken as an example to illustrate, and specifically, to implement the present invention, corresponding professional data needs to be maintained on the cloud platform:
the best edible thermometer: for each type of food, the optimal consumption temperature was recorded as shown in table 1; the data is obtained by counting relevant data on the internet.
TABLE 1
| Kind of food | Optimum temperature for eating |
| Fruit and vegetable | 0℃ |
| Meat product | -7℃ |
| Beer with improved flavor | 6 deg.C in summer and 10 deg.C in other seasons |
| … | … |
Refrigerating time per unit food (t)0) Table: recording the time required for cooling 1 ℃ of 1kg of different types of food according to the brand and model of the refrigerator which is mainstream in the market, as shown in table 2; the initial data is provided by the refrigerator manufacturer and can be corrected according to the measured data fed back by a large number of users.
TABLE 2
(Note: the numbers in the table are only examples, and the specific values and the size relationship have no practical significance)
For the brand and model of the refrigerator not referred to in the table above, the data of the refrigerator with similar capability can be searched in the table above as reference according to the refrigeration capability (basic attribute of the refrigerator, provided by the manufacturer of the refrigerator).
Based on the basic setting, the adaptive food refrigeration method for the temperature-variable chamber provided by the embodiment of the invention, as shown in fig. 4, specifically comprises the following steps:
step S401, a user uses the APP on the intelligent terminal, obtains the type and the specification (such as bottled food, canned food, bagged food and the like) of the food to be refrigerated through scanning a food label (a bar code and a two-dimensional code) or a manual input mode, and inputs the appointed eating time.
Step S402, the APP sends the food type to the cloud platform, and the report message contains the refrigerator model identification; the cloud platform obtains the optimal food temperature (namely the refrigeration target temperature) T of the food according to the optimal food temperature tabletAnd acquiring the unit food refrigerating time t for refrigerating the food by the refrigerator of the type according to the unit food refrigerating time table0And sending the data to the APP; the user can modify the T on APPt。
Step S403, the APP compares the food type specification, Tt, the scheduled eating time and t0To the temperature control unit of the refrigerator.
And S404, after the user puts the food into the refrigerator temperature-changing chamber, the temperature sensor of the temperature-changing chamber collects the current temperature of the food, and the weight sensor collects the weight of the food and reports the weight to the temperature control unit.
Step S405, the temperature control unit controls the temperature according to the weight of the food, the current temperature of the food and the temperature Tt、t0Calculating to reduce the temperature of the food to TtThe time required. If the time does not exceed the difference between the reserved eating time and the current time, the user requirement is satisfied, and the step S406 is continuously executed downwards; otherwise, the following 2 items are calculated respectively: the actual temperature of the food can reach T within the preset eating timetThe delayed eating time is fed back to the APP as an alternative suggestion for the user to adjust the demand.
Step S406, for the food types which can be stored at room temperature, such as fruits and vegetables, drinks, and the like, the temperature control unit starts the temperature-variable chamber to refrigerate at a proper time according to the calculated refrigeration time, so that when the appointed edible time is reached, the refrigeration temperature reaches the Tt(ii) a For other food types, the temperature control unit immediately initiates variable temperature chamber refrigeration. In the refrigeration process, the temperature sensor monitors the temperature change of food in real time and sends the temperature change to APP periodicallyFor the user to inquire.
Step S407, the temperature control unit records that the temperature of the food reaches TtCalculating the time required for reducing 1 ℃ of 1kg of the food, and periodically sending the time to a cloud platform together with the type specification of the food;
step S408, the cloud platform corrects corresponding data items in the table according to refrigeration data fed back by a large number of refrigerators and the existing refrigerator models in the unit food refrigeration schedule; and for the refrigerator model which does not exist in the unit food refrigeration schedule, establishing a data item in the schedule for the model according to the feedback data.
In order to better explain the present invention, the adaptive food refrigeration method proposed by the present invention is explained below through a specific application scenario. Assuming that summer season is in the present, a brand A refrigerator is arranged in a user's home (the refrigeration mode is direct cooling), and the user puts 500ml of beer with 4 tins into the refrigerator temperature-changing chamber at 16:00 and hopes to drink at 18: 00; the beer is currently at a temperature of 26 ℃. The complete flow is shown in fig. 5. In the figure, the "refrigerator" includes a temperature-changing chamber (including a sensor) and a temperature control unit.
As shown in fig. 5, the comprehensive call flow of the intelligent home appliance is as follows:
step 0: an optimal edible temperature table and a unit food refrigeration time table are pre-established on a cloud platform; the user puts beer into the refrigerator temperature changing chamber.
Step 1: the user scans the label on the beer can by using the APP on the mobile phone to obtain the beer with the food type and the can specification, and inputs the appointed eating time of 18: 00.
Step 2: the APP sends the food type specification to the cloud platform.
And step 3: the cloud platform respectively inquires the optimal edible temperature table and the unit food refrigeration time table to obtain the optimal drinking temperature T of the beer in summertAt 6 deg.C, the unit refrigerating time t of canned beer0For 4 minutes, send to APP.
And 4, step 4: the user does not modify Tt, and the APP combines the food type specification, Tt, the scheduled eating time and t0And sending the data to a refrigerator temperature control unit.
And 5: the temperature sensor of the temperature changing chamber collects the current temperature of the beer to be 26 ℃, and the weight sensor collects the weight of the beer to be about 2kg and reports the weight to the temperature control unit.
Step 6: the temperature control unit is used for controlling the temperature of the food according to the weight of the food of 2kg and the current temperature of the food of 26 ℃ and Tt＝6℃、t04 minutes, calculate the temperature drop to T for 4 tins of beertThe required time is about 160 minutes, and the current time 16:00 is 120 minutes from the scheduled eating time 18:00, which indicates that the user requirements cannot be met.
And 7: the temperature control unit calculates and generates the following 2 refrigeration suggestions: keeping the scheduled edible time at 18:00 constant, and adjusting the beer drinking temperature to 11 ℃; keeping the optimal drinking temperature at 6 deg.C, and postponing the drinking time to 18: 40. The advice is then sent to the APP for the user to adjust the needs.
And 8: after receiving the suggestion, the user keeps the drinking temperature unchanged, changes the scheduled eating time to 19:00 and sends the time to the temperature control unit again.
And step 9: the temperature control unit recalculates the refrigeration time according to the user requirement, and finds that the variable temperature chamber needs to be started for refrigeration at a ratio of 16: 20; since beer is among the food products that can be stored at room temperature, the temperature control unit will initiate variable temperature chamber refrigeration at 16: 20.
Step 10: in the refrigeration process, the temperature sensor of the temperature-variable chamber collects the temperature of the beer at regular time, reports the temperature to the temperature control unit, and forwards the temperature to the APP by the temperature control unit.
Step 11: and when the scheduled eating time is up to 19:00, the temperature control unit calculates the actual time required by reducing the temperature of 1 ℃ for 1kg of canned beer to be about 4.5 minutes according to the actual temperature of 8 ℃ reported by the sensor, and sends the data and the food type specification to the cloud platform.
Step 12: and the cloud platform receives a large amount of refrigeration data fed back by the A model direct cooling refrigerator, and the actual time required for reducing 1 ℃ by 1kg of canned beer is about 4.5 minutes, and the corresponding numerical value in the refrigeration time table of the unit food is changed from 4 minutes to 4.5 minutes.
In summary, it can be known that the refrigerator temperature control unit can calculate the time required for the food to reach the refrigeration target temperature according to the food characteristics, the preset eating time of the user, the unit refrigeration time of the food provided by the cloud platform, and other information. When the food can be cooled to the target temperature within the preset eating time of the user, the temperature control unit starts the temperature change chamber to refrigerate at a proper time according to the type of the food. After refrigeration is finished, the temperature control unit calculates the actual unit refrigeration time of the food and sends the actual unit refrigeration time to the cloud platform as a basis for the cloud platform to correct the unit food refrigeration time data.
