the position of the intelligent refrigerator, i.e. the actual placement position, can be obtained by a positioning device, e.g. by a position sensor or a GPS positioning device.

S2, when the actual placement position is located in a preset kitchen area, acquiring the current kitchen temperature of the kitchen area;

in the process of placing the intelligent refrigerator, various areas of a room, such as a kitchen area, a living room area, a bathroom area and the like, can be preset in the system, and after the actual placing position of the intelligent refrigerator is obtained, the actual placing position is compared with the preset areas in the system, namely, each area has a coordinate range, and the current coordinate of the intelligent refrigerator is obtained after the actual placing position is obtained.

Therefore, the actual placement position is compared with the preset area, if the current coordinate is in the coordinate range of the kitchen area, the intelligent refrigerator can be determined to be located in the kitchen area, and the judgment mode of whether the intelligent refrigerator is located in the living room area or the toilet area is the same as the judgment mode of the kitchen area.

When the actual placement position is determined to be located in a preset kitchen area, the current temperature of the kitchen area, namely the current kitchen temperature, is acquired at the moment, and the acquisition mode can be acquired after detection by a temperature sensor.

S3, obtaining the type of food materials stored in the intelligent refrigerator;

then, the food material type of the stored food materials stored in the intelligent refrigerator is obtained, wherein the food material type comprises vegetables, fruits, cooked wheaten food and the like, and particularly the name of each food material is also included, and the obtaining mode can be that the food material type of the stored food materials can be obtained after the camera installed in the intelligent refrigerator shoots and performs image recognition.

S4, acquiring the minimum required temperature of the stored food in a preset storage time based on the type of the food;

the preset storage duration can be set according to a time rule of cooking by a user, and of course, the preset storage duration can also be set arbitrarily. The minimum required temperature is the minimum temperature to be met in all the stored food materials for reaching the preset storage time.

Therefore, the preservation temperature of each pre-stored food material and the preservation time corresponding to the preservation temperature are obtained according to the obtained type of the food material, so that the corresponding preservation temperature can be obtained after the type of the food material and the preset preservation time are obtained, and then the minimum corresponding preservation temperature is obtained from all the preservation temperatures, namely the minimum required temperature.

Of course, in another possible implementation manner of this embodiment, the freshness of the vegetables and fruits may be identified by an electronic nose or a spectral imaging manner, and according to the obtained current freshness, different freshness, and a preservation time period and a preservation temperature corresponding to each freshness are also stored in the system, so that the accuracy of determining the minimum required temperature may be further improved according to the freshness of the vegetables or fruits placed in the refrigerator.

and then, acquiring the magnitude relation between the current kitchen temperature and the minimum required temperature, and acquiring a temperature control closing instruction when the current kitchen temperature is smaller than or equal to the minimum required temperature, and taking the temperature control closing instruction as a refrigerator temperature control instruction, so as to control the refrigeration closing of the refrigerator.

If the current kitchen temperature is greater than the minimum required temperature, generating a refrigerator temperature control instruction according to the minimum required temperature, and adjusting the storage temperature of the intelligent refrigerator to the minimum required temperature according to the refrigerator temperature control instruction.

S6, automatically adjusting the storage temperature of the intelligent refrigerator based on the refrigerator temperature control instruction to enable the storage temperature to be matched with the minimum required temperature;

finally, the storage temperature of the intelligent refrigerator is automatically adjusted according to the refrigerator temperature control instruction to enable the storage temperature to be matched with the minimum required temperature, namely, the intelligent refrigerator can be controlled to be closed for energy saving according to the refrigerator temperature control instruction, or controlled to be refrigerated according to the temperature value corresponding to the minimum required temperature, so that the temperature adjustment is automatically carried out on the food type and the current kitchen temperature, the accuracy of setting the storage temperature of the refrigerator can be ensured as much as possible, the shelf life of the food is prolonged, and unnecessary electric energy waste is reduced.

Further, in another implementation manner of this embodiment, an error value may be preset, that is, a temperature value of the error value is reduced based on the minimum required temperature, so that the storage temperature of the intelligent refrigerator matches with the minimum required temperature, and the matching manner may be to set an error upper limit value and an error lower limit value for the minimum required matching temperature, if the storage temperature is between the error upper limit value and the error lower limit value, the matching is performed, otherwise, the matching is not performed.

In another implementation manner of this embodiment, the error value may be set by pre-storing a plurality of sets of temperature values in the system, where each set of temperature values corresponds to a difference value, and each set of temperature values includes two different temperature values, and a maximum value and a minimum value in the temperature values may be set according to a local actual situation.

When the current kitchen temperature and the minimum required temperature are obtained, the intelligent refrigerator can be matched with a plurality of groups of temperature values, and when the current kitchen temperature and the minimum required temperature are matched with the same temperature values, the corresponding difference value can be obtained, namely the difference value is used as an error value, so that the refrigerating temperature of the intelligent refrigerator can be close to the minimum required temperature as much as possible.

Referring to fig. 2, since the kitchen does not need to be used all the time, only a living room area, a bedroom area, or the like may need to be heated during the heating process, and the kitchen area does not need to be heated, so that the current kitchen temperature of the kitchen area is different at different times.

Thus, in order to obtain the current kitchen temperature more accurately, in another embodiment, obtaining the current kitchen temperature of the kitchen area comprises:

s11, acquiring a current outdoor temperature value and a preset temperature interval for heating a kitchen area;

The outdoor temperature value can be obtained through detection of a temperature sensor arranged outdoors, and the preset temperature interval refers to a preset interval for heating the kitchen area when the outdoor temperature value is within the preset temperature interval, wherein the preset temperature interval can be set according to actual conditions.

S12, judging whether the outdoor temperature value is matched with a preset temperature interval or not;

that is, whether the outdoor temperature value is within the preset temperature interval is judged, if the outdoor temperature value is within the preset temperature interval, the outdoor temperature value and the outdoor temperature value are proved to be matched, otherwise, the outdoor temperature value and the outdoor temperature value are not matched.

S13, if the outdoor temperature value is not matched with the preset temperature interval, taking the outdoor temperature value as the current kitchen temperature;

if the outdoor temperature value is not matched with the preset temperature interval, the fact that the kitchen area is not required to be heated at the moment is proved, and the fact that the outdoor temperature is higher at the moment is also shown, so that the outdoor temperature value can be regarded as being equal to the current kitchen temperature, and the outdoor temperature value can be directly regarded as the current kitchen temperature at the moment.

S14, if the outdoor temperature value is matched with a preset temperature interval, acquiring the current time and the preset kitchen heating time;

if the outdoor temperature value is matched with the preset temperature interval, it is proved that the temperature of the kitchen area is lower at the moment, heating is needed, and the cooking time of the kitchen area is shorter, so that whether the current time is the cooking time or not is also needed to be determined at the moment, and whether the heating is needed or not is determined. Thus, the current time and the preset kitchen warming time are acquired at this time.

The current time can be obtained through the timing of a system timer, and the kitchen heating time, namely the time needed for cooking in a kitchen area, is an interval value. For example, it may be set to 5 to 7 in the morning, 11 in the morning to 1 in the afternoon, and 5 in the afternoon to 7 in the afternoon. The specific time can be set according to actual requirements.

S15, judging whether the current time is matched with the kitchen heating time or not;

that is, judging whether the current time is in the range of the kitchen heating time, if the current time is in the range of the kitchen heating time, proving that the current time and the kitchen heating time are matched, otherwise, not matching.

S16, if the current time is matched with the kitchen heating time, controlling the floor heating of the kitchen area to heat based on a preset heating temperature value;

if the current time is matched with the kitchen heating time, the kitchen needs to be heated at the moment, so that a user can cook conveniently, and the floor heating of the kitchen area is controlled to heat according to a preset heating temperature value at the moment. The preset heating temperature value may be set to 25 ℃, or may be set to 23 ℃ or 20 ℃ according to the actual requirement of the user.

Of course, in the actual heating process, heating equipment such as an air conditioner provided in the kitchen area may be controlled to perform heating according to a preset heating temperature value.

S17, acquiring the region temperature of the kitchen region after the preset time length, and taking the region temperature as the current kitchen temperature;

since a period of time is required for heating the kitchen area, the area temperature of the kitchen area after a preset period of time is obtained, and the area temperature can be obtained by a temperature detection device such as a temperature sensor, and the area temperature is used as the current kitchen temperature.

The preset time length can be set according to actual conditions, and different preset time lengths can be set according to different outdoor temperature values, namely different temperature values and time lengths corresponding to the temperature values can be prestored in the system, and when the outdoor temperature values are acquired, the corresponding time lengths can be matched and used as the preset time lengths, so that the accuracy of the acquired current kitchen temperature can be ensured as much as possible.

S18, if the current time is not matched with the kitchen heating time, acquiring a predicted temperature value based on an outdoor temperature value and a preset heat preservation difference value, and taking the predicted temperature value as the current kitchen temperature;

if the current time is not matched with the kitchen heating time, the fact that the kitchen area is not required to be heated at the moment is proved, and the outdoor temperature value is smaller than the current temperature value of the kitchen area at the moment because the rooms have certain heat preservation property, so that the predicted temperature value can be obtained according to the outdoor temperature value and a preset heat preservation difference value at the moment, and the predicted temperature value is taken as the current kitchen temperature.

The obtained value is the predicted temperature value, wherein the heat preservation difference value can be set according to actual conditions, so that the accuracy of the obtained current kitchen temperature is improved as much as possible.

Therefore, through the mode, the current kitchen temperature can be determined according to different outdoor temperature values and different times, so that the acquired current kitchen temperature is more accurate, and the accuracy of temperature adjustment of the intelligent refrigerator can be ensured as much as possible.

Referring to fig. 3, the insulation difference is set due to the insulation of the room, and different insulation materials have different insulation properties, so in another embodiment, obtaining the insulation difference includes:

s21, acquiring heat insulation material information and window information of a wall body;

s22, acquiring preset temperature-material information;

s23, acquiring a corresponding temperature difference value based on the heat insulation material information, the window information and the temperature-material information, and taking the temperature difference value as a heat insulation difference value.

Specifically, the heat insulation material information and window information of the wall body are obtained, wherein the heat insulation material information comprises a heat insulation material name, a heat insulation material thickness, a heat insulation material type and the like, the obtaining mode can be obtained through transmission input of terminal equipment, the window information comprises a window layer number, such as a single layer or a double layer, and the obtaining mode is the same as that of the heat insulation material information.

And then acquiring and acquiring preset temperature-material information, wherein the temperature-material information comprises preset heat insulation materials, window information corresponding to the preset heat insulation materials and temperature difference values corresponding to the window information, and the temperature difference values are data prestored in a system.

And finally, acquiring a corresponding temperature difference value based on the heat insulation material information, the window information and the temperature-material information, and taking the temperature difference value as a heat insulation difference value. The method comprises the steps of comparing the heat insulation material information with preset heat insulation materials in temperature-material information to obtain preset heat insulation materials identical to the heat insulation material information, obtaining corresponding window information in the temperature-material information, matching the obtained window information with the window information in the temperature-material information, and obtaining identical window information, so that an obtained temperature difference value, namely a heat insulation difference value, is finally determined.

Through the mode, different heat preservation difference values can be determined according to different heat preservation materials and window information, and then the accuracy of the acquired current kitchen temperature can be ensured as much as possible.

Referring to fig. 4, if the difference between the room temperature and the temperature of the refrigerator is too large, the heat exchange rate between the refrigerator and the surrounding environment is increased, thus causing frequent cooling of the intelligent refrigerator, which leads to a reduction in the service life of the refrigerator and waste of electric power.

Therefore, in order to increase the service life of the refrigerator as much as possible and save electric energy as much as possible, in another embodiment, after acquiring the zone temperature of the kitchen zone after the preset period of time and taking the zone temperature as the current kitchen temperature, the method further includes:

s31, acquiring a refrigerator kitchen temperature difference value based on the current kitchen temperature and the minimum required temperature;

S32, judging whether the temperature difference value of the refrigerator kitchen exceeds a temperature threshold value;

the temperature threshold can be set according to actual conditions, whether the temperature difference value of the refrigerator and the kitchen exceeds the temperature threshold is judged, namely whether the heat exchange speed between the refrigerator and the kitchen is overlarge is judged, and if the temperature difference value of the refrigerator and the kitchen exceeds the temperature threshold, the refrigerator is proved to refrigerate more times.

S33, if the temperature of the kitchen exceeds the preset temperature, acquiring a kitchen temperature control and regulation instruction;

if the refrigerator kitchen temperature difference does not exceed the temperature threshold, no temperature adjustment is required at this time. If the temperature difference value of the refrigerator kitchen exceeds the temperature threshold value, the current temperature value of the kitchen area needs to be adjusted at the moment, so that the kitchen temperature control adjusting instruction is acquired at the moment.

S34, adjusting a heating temperature value based on a kitchen temperature control adjusting instruction so that a refrigerator kitchen temperature difference value does not exceed a temperature threshold value;

the temperature adjusting command includes a temperature adjusting value, which is a difference obtained by subtracting a temperature threshold from a refrigerator kitchen temperature difference, or a value larger than the difference, that is, the temperature adjusting value may be added with an additional value based on the obtained difference, and the additional value may be set according to actual requirements.

That is, according to the kitchen temperature control adjustment instruction, the heating temperature value before adjustment is controlled to subtract the temperature adjustment value, the heating temperature value after adjustment is obtained, and the kitchen area is heated according to the heating temperature value after adjustment, so that the temperature difference value of the refrigerator kitchen does not exceed the temperature threshold value, the rate of heat exchange between the refrigerator and the kitchen is reduced, the starting times of the refrigerator are reduced, the service life of the refrigerator is prolonged as much as possible, and the electric energy is saved as much as possible.

Referring to fig. 5, when the kitchen area is cooled, other areas adjacent to the kitchen area, such as a living room area or a bathroom area, may not need to be cooled, and the temperature of the adjacent areas may be transferred to the kitchen area, so that the error rate of temperature adjustment of the kitchen area may be large.

In order to reduce the influence of the adjacent region temperature on the kitchen region as much as possible, the error rate of the kitchen region temperature adjustment is reduced, in another embodiment, after adjusting the heating temperature value based on the kitchen temperature control adjustment instruction so that the refrigerator kitchen temperature difference value does not exceed the temperature threshold value, further comprising:

S43, if the equipment is not matched, acquiring an equipment starting instruction;

if the zone temperature value matches the adjusted current kitchen temperature, it is demonstrated that the zone temperature value of the adjacent zone has less effect on the kitchen zone.

If the zone temperature value does not match the adjusted current kitchen temperature, it is proved that the zone temperature value of the adjacent zone has a greater influence on the kitchen zone at this time, so that the device opening command is acquired at this time in order to reduce this influence as much as possible.

S44, controlling the opening of the electric curtains and/or electric door curtains of the kitchen area and the adjacent area based on the equipment opening instruction;
