[0039] In the embodiments of the present disclosure, smart home appliances refer to home appliances that are formed by introducing microprocessors, sensor technology, and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage the smart home appliances.

[0040] In the disclosed embodiments, the terminal device refers to an electronic device with a wireless connection function. The terminal device can communicate with the above-mentioned smart home appliances by connecting to the Internet, or can communicate with the above-mentioned smart home appliances directly through Bluetooth, WiFi, etc. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a vehicle-mounted device built into a hover car, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, etc., or any combination thereof, wherein wearable devices include, for example: smart watches, smart bracelets, pedometers, etc.

[0041] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the refrigerator includes: a box body 300. A refrigerating chamber 310 is defined inside the box body 300, and an air outlet 320 is provided on the side wall of the refrigerating chamber 310. In this way, food is placed in the refrigerating chamber 310 inside the box body 300 for refrigeration, and the cold air flow blown out by the air outlet 320 exchanges heat with the food to refrigerate the food.

[0042] Optionally, the air outlet 320 is disposed on the rear side wall of the refrigerating chamber 310. In this way, air is discharged to the front side through the air outlet 320, so that the cold air flow can better exchange heat with the food, thereby improving the refrigeration effect.

[0043] Optionally, the refrigerator further includes a distance measuring module 330, which is disposed on the side wall of the refrigerating chamber 310 where the air outlet 320 is located. In this way, the distance between the food placed in the refrigerating chamber 310 and the side wall where the air outlet 320 is located is detected by the distance measuring module 330, thereby improving the accuracy of obtaining the wind distance.

[0044] Optionally, the four side regions of the air outlet 320 are all provided with distance measuring modules 330. In this way, since the food placed in the refrigerated compartment 310 is uneven, and the air outlet 320 is in a planar shape, the four side regions of the air outlet 320 are all provided with distance measuring modules 330, so that the distance between the food facing the planar air outlet region of the air outlet 320 and the air outlet 320 can be obtained at the same time.

[0045] Specifically, the distance measuring module 330 is disposed on the rear side wall of the refrigerating chamber 310 , and the distance measuring module 330 is an ultrasonic distance measuring module 330 .

[0046] Optionally, a shelf 340 is provided inside the refrigerating chamber 310, and the food in the refrigerating chamber 310 is placed on the shelf 340, and the shelf 340 is movably provided and can slide toward or away from the plane where the air outlet 320 is located. In this way, the food is placed on the shelf 340, and the shelf 340 can slide toward or away from the air outlet 320 to change the wind receiving distance between the food and the side wall where the air outlet 320 is located.

[0047] Optionally, two vertical side walls opposite to each other of the refrigerating chamber 310 are provided with guide grooves 350, and two sides of the shelf plate 340 are respectively embedded in the corresponding guide grooves 350. A driving motor 360 is provided in each of the two guide grooves 350, and the output ends of the driving motor 360 are respectively engaged with the side edges of the corresponding shelf plate 340. In this way, the driving motors 360 provided in the two guide grooves 350 are used to drive the two sides of the shelf plate 340 respectively, so that the shelf plate 340 can slide toward or away from the air outlet 320, and the sliding stability of the shelf plate 340 is higher by the guidance of the guide grooves 350.

[0048] Specifically, both sides of the shelf plate 340 have a rack structure, and both sides of the shelf plate 340 are meshed with the output end of the driving motor 360 in the corresponding guide groove 350 through the rack structure.

[0049] Optionally, the length of the shelf 340 along the sliding direction thereof is less than the length of the refrigerating compartment 310. In this way, the shelf 340 has a sliding margin in the refrigerating compartment 310, so that the shelf 340 can slide toward or away from the air outlet 320.

[0050] Optionally, a mesh plate is provided below the shelf 340, and the two sides of the mesh plate are respectively fixedly connected to the two opposite side walls of the refrigerating chamber 310, and the projection of the shelf 340 falls into the mesh plate in the vertical direction. In this way, when the shelf 340 slides, the food placed on the shelf 340 is at risk of falling, and the provision of the mesh plate can catch the fallen food.

[0051] It can be understood that the driving motors 360 disposed in the two guide slots 350 are both controlled by a processor.

[0052] Optionally, the refrigerator further comprises a buzzer 370, and the buzzer 370 is arranged on the side wall of the refrigerator. In this way, the buzzer 370 can emit a buzzing alarm sound, so that the user can perceive the prompt more intuitively.

[0053] Combination Figure 4 As shown, in one embodiment, a control method for a refrigerator includes:

[0054] S01, the processor obtains the wind distance between the food in the cold storage room and the air outlet;

[0055] S02: When the wind distance is less than or equal to a set threshold, the processor sends an alarm message to the user.

[0056] By adopting the control method for a refrigerator provided by the embodiment of the present disclosure, the food is placed in the cold storage room for refrigeration, and the cold air flow blown out from the air outlet is used to exchange heat with the food to refrigerate the food. The wind distance between the food and the air outlet is obtained, and a set threshold for the risk of frostbite of the food is pre-set. When the wind distance is less than or equal to the set threshold, the food is at a high risk of frostbite, so an alarm message is sent to the user to remind the user to adjust the position of the food in time to avoid placing the food close to the air outlet, thereby reducing the risk of frostbite of the food, improving the preservation effect of the food, and ensuring the taste of the food. While reducing the risk of frostbite of the food, it can reduce the obstruction of the food to the airflow of the air outlet, so that the temperature uniformity in the cold storage room is higher.

[0057] It can be understood that the air outlet is a planar air outlet with an air outlet plane, and the wind receiving distance refers to the distance between the food and the air outlet plane of the air outlet along the air outlet direction of the air outlet.

[0058] Optionally, the threshold is set to one tenth of the length of the refrigerating compartment in the air outlet direction of the air outlet. In this way, the risk of food being frostbitten can be reduced while ensuring the food storage capacity in the refrigerating compartment.

[0059] Optionally, the processor obtains the wind distance between the food in the cold storage room and the air outlet, including: the processor obtains the wind distance between the food in the cold storage room and the air outlet sent by the distance measuring module. In this way, the distance measuring module detects the wind distance between the food in the cold storage room and the air outlet, and the processor obtains the wind distance data sent by the distance measuring module, which can simplify the process of obtaining the wind distance and improve the accuracy of obtaining the wind distance.

[0060] Optionally, the processor obtains the windward distance between the food in the cold storage room and the air outlet sent by the distance measuring module, including: the processor obtains multiple distance values ​​between the food and the air outlet sent by four distance measuring modules set in the four side areas of the air outlet, and determines the smallest of the multiple distance values ​​as the windward distance. In this way, in order to improve the accuracy of distance measurement, distance measuring modules are set in the four side areas of the upper, lower, left and right of the air outlet. The processor simultaneously obtains multiple distance values ​​between the food and the air outlet sent by the four distance measuring modules, and determines the smallest distance value as the windward distance, which can reduce the error caused by the uneven placement of food, make the acquisition accuracy of the windward distance higher, and further reduce the risk of frostbite of food.

[0061] Exemplarily, the air outlet is a rectangular opening structure, and the air outlet forms a planar air outlet area. The food facing the planar air outlet area of ​​the air outlet is also uneven, so distance measurement modules are set in the four side areas of the air outlet to respectively detect the distance between the food facing the four side areas of the air outlet and the planar air outlet area of ​​the air outlet. The processor simultaneously obtains four distance values ​​sent by the four distance measurement modules, namely d1, d2, d3 and d4, and determines by calculation that the smallest distance value among d1, d2, d3 and d4 is the wind-receiving distance.

[0062] Combination Figure 5 As shown, in one embodiment, a control method for a refrigerator includes:

[0063] S01, the processor obtains the wind distance between the food in the cold storage room and the air outlet;

[0064] S02, when the wind distance is less than or equal to a set threshold, the processor sends an alarm message to the user;

[0065] S03, the processor controls the food in the cold storage room to slide back to the plane where the air outlet is located, so that the wind exposure distance is greater than a set threshold.

[0066] With the control method for a refrigerator provided by the embodiment of the present disclosure, when the wind distance between the food and the air outlet is less than or equal to a set threshold, the processor sends an alarm message to the user to prompt the user to adjust the placement of the food, thereby reducing the risk of frostbite of the food and improving the temperature uniformity inside the refrigerated compartment. In order to avoid the situation where the user does not adjust the placement of the food when not noticing the alarm message, the processor controls the food to slide back to the plane where the air outlet is located, so that the food is away from the air outlet, so that the wind distance is greater than the set threshold, reducing the risk of frostbite of the food.

[0067] Optionally, the processor controls the food in the refrigerating room to slide back toward the plane where the air outlet is located so that the wind exposure distance is greater than a set threshold, including: the processor controls the shelf plate to slide back toward the plane where the air outlet is located so that the wind exposure distance is greater than a set threshold. In this way, since the food in the refrigerating room is placed on the shelf plate, the processor controls the food to move back toward the air outlet, which is actually controlling the shelf plate to move back toward the plane where the air outlet is located, so that the food is away from the air outlet, increasing the wind exposure distance of the food, and reducing the risk of frostbite of the food.

[0068] Optionally, the processor obtains the relationship between the wind exposure distance and a set threshold value while controlling the shelf to slide back to the plane where the air outlet is located; when the wind exposure distance is greater than the set threshold value, the processor controls the shelf to stop sliding. In this way, when the shelf slides to a wind exposure distance greater than the set threshold value, the wind exposure distance of the food is relatively large, and the risk of the food being frostbitten is reduced. Considering the amount of food stored in the refrigerator, the shelf is controlled to stop sliding.

[0069] Optionally, the processor controls the shelf to slide away from the plane where the air outlet is located, including: the processor simultaneously controls two drive motors meshed with the two side edges of the shelf to rotate, so as to drive the shelf to slide away from the plane where the air outlet is located. In this way, since the two opposite sides of the shelf are embedded in the guide grooves of the inner walls of the refrigerated compartment on the opposite sides, and the two guide grooves are provided with drive motors that respectively mesh with the two opposite sides of the shelf, the processor simultaneously controls the two drive motors to rotate to synchronously drive the shelf to slide, thereby improving the sliding stability of the shelf.

[0070] Optionally, the processor simultaneously controls the output ends of two driving motors meshed with the two side edges of the shelf to rotate clockwise to drive the shelf to slide back to the plane where the air outlet is located.

[0071] Optionally, when the wind distance is greater than a set threshold, the processor controls the shelf to stop sliding, including: the processor simultaneously controls two drive motors engaged with two sides of the shelf to stop rotating. In this way, the processor simultaneously controls the two drive motors to stop rotating, so that the shelf stops sliding.

[0072] Optionally, the processor controls the food in the cold storage room to slide back to the plane where the air outlet is located, including: the processor obtains the issuance time of the alarm information; when the issuance time is greater than or equal to the operation time, the processor again determines the relationship between the wind-exposed distance and the set threshold value; when the wind-exposed distance is still less than or equal to the set threshold value, the processor controls the food to slide back to the plane where the air outlet is located. In this way, when the wind-exposed distance is less than or equal to the set threshold value, the processor sends an alarm message to the user to remind the user that the food is too close to the air outlet, there is a high risk of frostbite, and the placement of the food needs to be adjusted. When the user receives the alarm message, in most cases, the placement of the food will be adjusted, and there is no need to control the food to slide back to the air outlet. Therefore, the processor obtains the issuance time of the alarm information and reserves sufficient operation time for the user to adjust the position of the food. Therefore, when the issuance time of the alarm information is greater than or equal to the operation time, the processor again judges the relationship between the wind exposure distance of the food and the set threshold. When the wind exposure distance is still less than or equal to the set threshold, the food is controlled to slide back to the air outlet, reserving time for the user to adjust. While reducing the risk of frostbite of the food, frequent control of the food to slide back to the air outlet is avoided, which affects the storage amount of the food.

[0073] Optionally, the processor does not perform sliding control on the food when the wind distance is greater than a set threshold.

[0074] Optionally, the operation time is determined by the user's current location. In this way, since the area where the user is located after placing the ingredients is variable, and there is a situation where the ingredients move during the storage process, resulting in the wind distance being less than or equal to the set threshold, the user may be far away from the refrigerator, and the required operation time is also longer. Therefore, the operation time is determined by the user's current location, so that the operation time changes according to the user's location, and sufficient operation time is reserved for the user.

[0075] Optionally, when the sending duration is greater than or equal to the operation duration, before the processor re-determines the size relationship between the wind-exposed distance and the set threshold, the further step includes: the processor obtains the current location of the user; the processor determines the operation distance between the user and the refrigerated compartment according to the current location of the user; the processor determines the corresponding operation duration according to the distance interval of the operation distance. In this way, the processor determines the user's operation distance by obtaining the user's current location, and then determines the corresponding operation duration according to the distance interval of the operation distance, so that the user has sufficient operation time to readjust the placement of the food.

[0076] Optionally, there are three preset distance intervals, namely, the first distance interval, the second distance interval and the third distance interval, the operation time corresponding to the first distance interval is T1, the operation time corresponding to the second distance interval is T2, and the operation time corresponding to the third distance interval is T3, wherein the maximum value in the first distance interval is less than the minimum value in the second distance interval, the maximum value in the second distance interval is less than the minimum value in the third distance interval, T1 is less than T2, and T2 is less than T3; when the processor determines that the operation distance between the user and the refrigerated compartment is in the first distance interval, the operation time is determined to be T1; when the processor determines that the operation distance between the user and the refrigerated compartment is in the second distance interval, the operation time is determined to be T2; when the processor determines that the operation distance between the user and the refrigerated compartment is in the third distance interval, the operation time is determined to be T3. In this way, when the user's operation distance is in the first distance interval, the user is close to the refrigerator at this time, so the determined operation time T1 is relatively short. When the user does not rearrange the food within the T1 time, it is assumed that the user has received an alarm message and controls the shelf to slide back to the air outlet to reduce the risk of frostbite of the food. When the user's operating distance is in the second distance interval, the operating time is determined to be T2. At this time, the user is at a moderate distance from the refrigerator, so the relatively moderate operating time T2 is determined. When the user's operating distance is in the third distance interval, the user is far away from the refrigerator, and the time it takes for the user to move to the front of the refrigerator to operate is relatively long, so the operating time T3 is determined to reserve enough operating time for the user.

[0077] Optionally, the refrigerator is also preset with a fourth distance interval, and the operation time corresponding to the fourth distance interval is T4, wherein the minimum value in the fourth distance interval is greater than the maximum value in the third distance interval, and the operation time T4 is less than T1; when the processor determines that the operation distance between the user and the refrigerated compartment is in the fourth distance interval, the operation time is determined to be T4. In this way, when the user's operation distance is in the fourth distance interval, the user is relatively far away from the refrigerator at this time, and the user may be out, so the processor determines the operation time to be the relatively minimum T4, and immediately controls the food to slide back to the air outlet after T4. In this embodiment, it is assumed by default that the user cannot rearrange the food. In order to reduce the risk of frostbite of the food, the food is driven to slide back to the air outlet after a relatively short period of time, thereby increasing the wind exposure distance of the food.

[0078] For example, most refrigerators are installed in the user's home, and the user's home is equipped with a face collection module such as a camera, which can obtain the user's location through the camera, and then calculate the user's operating distance. The refrigerator's processor can also establish a concentric connection with a mobile terminal carried by the user, such as a mobile phone, a smart bracelet, etc., and determine the user's location by obtaining the location of the mobile phone and the smart bracelet, thereby obtaining the user's operating distance.

[0079] In one embodiment, the processor controls the shelf plate to slide back to the plane where the air outlet is located so that the wind receiving distance is greater than a set threshold, and further includes: the processor determines the difference between the set threshold and the wind receiving distance, and the allowable sliding value of the shelf plate sliding back to the air outlet; when the allowable sliding value is greater than the difference between the set threshold and the wind receiving distance, the processor controls the shelf plate to slide back to the plane where the air outlet is located. In this way, the sliding operation of the shelf plate back to the air outlet can effectively reduce the risk of freezing of food, and avoids reducing the storage volume of food in the cold storage room while the risk of freezing of food is not reduced.

[0080] It can be understood that the allowable sliding value of the shelf plate sliding back toward the air outlet refers to: the value to which the shelf plate slides from the current position back toward the air outlet to the maximum limit.

[0081] Combination Figure 6 As shown, in one embodiment, a control method for a refrigerator includes:

[0082] S01, the processor obtains the wind distance between the food in the cold storage room and the air outlet;

[0083] S02, when the wind distance is less than or equal to a set threshold, the processor sends an alarm message to the user;

[0084] S03, the processor controls the food in the cold storage room to slide back to the plane where the air outlet is located, so that the wind exposure distance is greater than a set threshold;

[0085] S04, the processor obtains the difference between the wind distance and the set threshold;

[0086] S05, when the difference is greater than a set threshold, the processor controls the shelf to slide toward the plane where the air outlet is located by the set threshold.

[0087] By adopting the control method for a refrigerator provided by the embodiment of the present disclosure, in the process of storing food, if food close to the plane where the air outlet is located is taken away, the processor obtains the difference between the wind exposure distance and the set threshold in real time. When the difference is greater than the set threshold, the wind exposure distance of the food is relatively large, and the distance between the food and the air outlet is far. In order to improve the preservation effect of food and ensure the storage amount of food, the shelf is controlled to slide toward the plane where the air outlet is located to set a threshold, so that the food is relatively close to the air outlet, and the wind exposure distance of the food can reduce the risk of frostbite of the food, leaving a margin for the subsequent sliding adjustment of the shelf.

[0088] In one embodiment, the processor sends an alarm message to the user, including: the processor controls a buzzer to send an alarm message to the user. In this way, by setting a buzzer on the refrigerator, the processor controls the buzzer to emit a buzzing sound, thereby sending an alarm message to the user, so that the user can perceive the alarm prompt more intuitively.

[0089] Optionally, the processor obtains the duration of issuing the alarm information, including: the processor obtains the duration of sounding of a buzzer.

[0090] In another embodiment, the processor sends an alarm message to the user, including: the processor controls the refrigerator to send an alarm message to a terminal in the area where the user is located. In this way, when the wind exposure distance of the food is less than or equal to the set threshold, the user may be far away from the refrigerator, so the processor controls the refrigerator to send an alarm message to the terminal in the area where the user is located, so that the user can perceive the alarm message more intuitively.
