Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Referring to Fig. 1, the present invention provides a refrigerator 100 in which a defrosting compartment is provided. The thawing room can be provided with a thawing module. The thawing module can be a radio frequency thawing module or an infrared thawing module. The user can defrost the food through the thawing module in the thawing room. When the thawing module is not working, the thawing room runs in the freezing mode.

In this embodiment, the refrigerator 100 is communicatively connected with the mobile terminal 200. Specifically, the refrigerator 100 and the mobile terminal 200 may communicate through the Internet. For example, the refrigerator 100 may be a 5G smart refrigerator based on an eSIM card. The mobile terminal 200 may be a mobile device such as a smart bracelet or a smart phone.

In this embodiment, the mobile terminal 200 and the refrigerator 100 can be connected via a 5G network communication. In this way, the mobile terminal 200 can send the location information (for example, positioning by GPS) that it locates to the refrigerator. 100. Of course, the mobile terminal 200 can also send the located geographic location information to the network server, and the server then forwards the received mobile terminal 200 information directly to the refrigerator 100, or the received mobile terminal 200 After the information is processed, it is sent to the refrigerator 100.

In this way, after the refrigerator 100 obtains the geographic location information of the mobile terminal 200, it can control the defrosting module to work according to the geographic location information of the mobile terminal 200.

Referring to FIG. 2, in an embodiment of the present invention, the thawing control method of the refrigerator 100 includes the following steps:

Receiving multiple geographic location information sent by the mobile terminal 200 at multiple time points;

Forming the moving route and average moving speed of the mobile terminal 200 according to the multiple geographic location information;

Judge whether you are on the way home according to the moving route;

In this embodiment, the mobile terminal 200 can obtain its own geographic location information in real time or at intervals, and can send the obtained geographic location information to the cloud via the Internet.

The geographic location information sent to the cloud can be directly forwarded to the refrigerator 100, or can be received by the server.

After the refrigerator 100 or the server receives multiple geographic location information sent by the mobile terminal 200 at multiple points in time, it can form the moving route of the mobile terminal 200 according to the changes in time and geographic location information, and calculate the average moving speed of the mobile terminal 200 . For example, receiving the first geographic location information, the second geographic location information, and the third geographic location information of the mobile terminal 200 10 minutes ago, 5 minutes ago, and 3 minutes ago, the first geographic location information, the second geographic location information, and the The geographic location information and the third geographic location information are sorted to form the moving route of the mobile terminal 200, and the distance between the first geographic location and the second geographic location, and the distance between the second geographic location and the third geographic location is obtained, and the mobile terminal 200 is calculated. The average speed of movement.

If it is judged that the user is on the way home based on the moving route, at this time, analyze the estimated time of arrival based on the moving route and average moving speed, and send control instructions to the unfreezing module according to the estimated arrival time, such as turning on the unfreezing module, controlling the unfreezing power, and calculating Defrosting completion time, etc., to ensure that users can use high-quality ingredients in time after returning home, without waiting.

Of course, if it is determined that it is not on the way home, it will continue to operate in the freezing mode. Ensure that the ingredients in the thawing room will not deteriorate.

In this way, the thawing module is automatically controlled according to the expected arrival time, which can reduce the user's intervention and take into account the quality of the ingredients and the thawing timeliness.

In an embodiment of the present invention, the step of "determining whether you are on the way home according to the moving route" includes:

In this embodiment, "determining whether the location information is gradually approaching the geographic location of home" may be calculating the distance between the geographic location of the mobile terminal 200 and the geographic location of the home at multiple time points. If the trend is small, it is determined that the geographic location of the mobile terminal 200 is gradually closer to the geographic location of the home.

The home route can be a route from the geographic location of the mobile terminal 200 to the geographic location of the refrigerator 100. There may be multiple home routes, which can be pre-planned and set by the user, or they can be obtained from the map based on the real-time location. Home route. When it is detected that the route of the mobile terminal 200 coincides with the route home, and the geographic location of the mobile terminal 200 is close to the geographic location of home, it can be determined that the user is on the way home. If the moving route is a dot, it can be determined that the user's position is fixed and the operation continues in the freezing mode. If the user's location information is far away from the geographic location of the home, or there is no overlap between the moving route and the home route, it can be determined that the user is far away from home, or is going to another location, and continues to operate the defrosting compartment in the freezing mode.

For example, the mobile terminal 200 sends the first geographic location information, the second geographic location information, and the third geographic location information to the cloud 8 minutes ago, 5 minutes ago, and 3 minutes ago. If the information and the third geographic location information are close to overlap, and the moving track is close to a dot, it can be determined that the user’s location is fixed and continue to operate in the frozen mode; otherwise, calculate the first geographic location, the second geographic location, and the third geographic location. If the distance of the home’s geographic location is reduced, the route home from the first geographic location to the home location can be obtained, and the moving route and the home route can be compared. If so, it can be determined that the user is going home. On the way, start to calculate the estimated time to arrive home; if the distance increases or the moving route deviates from the home route, it continues to operate in the freezing mode.

In this way, it can be automatically determined in real time whether the user is on the way home based on the moving route, which can prevent the user from temporarily changing the itinerary and affecting the defrosting quality and defrosting timeliness.

Further, in an embodiment of the present invention, the step of "calculating the estimated time to home based on the moving route and the average moving speed" includes:

In this embodiment, the mode of travel may include walking, biking, self-driving, and taking public transportation. The selected home route may be a route actually used by the user among a plurality of home routes. "Determining a travel mode according to the moving route and the average moving speed" may include: preliminarily judging a possible travel mode according to the average moving speed; and determining a travel mode according to the moving route.

"Determine a selected home route according to the movement route and the travel mode" may be marking a route that overlaps the movement route and matches the user's travel mode as the selected home route. For example, if the travel mode is public transportation, the bus route is marked as the selected home route; if the travel mode is walking, the walkable route is marked as the selected home route.

In "Calculate the earliest estimated home time based on the selected route home and the road condition information", the road condition information can be the road condition information of the entire selected route home, which can specifically include information such as traffic flow, accident occurrence, etc. The road condition information calculates the time it may take for the mobile terminal 200 to go home with the selected route home. The earliest estimated home time is the earliest possible home time for the user to deal with emergencies on the road as quickly as possible. For example, in the event of an accident, the fastest unblocked time on the road is estimated, and the earliest estimated time to arrive home is calculated with the fastest unblocked time.

Further, in an embodiment of the present invention, the step of "sending a control instruction to the unfreezing module according to the estimated arrival time" includes:

The thawing power can correspond to the thawing completion time. The thawing power affects the quality of the ingredients. The greater the thawing power, the shorter the thawing completion time, and the worse the quality of the ingredients after the thawing is completed. In this way, the thawing opening time and the thawing power are controlled according to the expected arrival time, so as to provide the best ingredients while ensuring the thawing time.

In an embodiment of the present invention, the step of "controlling the opening time of thawing and its corresponding thawing power according to the estimated arrival time" includes:

If yes, turn on the thawing module when the thawing completion time corresponding to the thawing with the optimal thawing power is equal to the estimated home time.

In this embodiment, the database or server of the refrigerator 100 may store the optimal thawing power corresponding to each ingredient to be thawed, and the thawing completion time-thawing power table, and the corresponding optimal thawing power can be directly obtained according to the information of the ingredients. According to the thawing power, the corresponding thawing completion time can be queried, and the corresponding preferred thawing power can also be queried according to the thawing completion time.

The food information can be directly obtained through the RFID recognition module, image recognition module, etc., provided in the refrigerator, or can be directly input by the user.

When the defrosting module is turned on at the best defrosting power at the current time, the defrosting completion time of the defrosting module is earlier than the estimated home arrival time, the estimated home arrival time can be continuously calculated to determine whether the estimated home arrival time is equal to the defrosting completion time when the defrosting module is turned on with the best defrosting power When the estimated home time is equal to the thawing completion time when the thawing module is turned on with the best thawing power, the thawing module is turned on with the best thawing power, so that the best thawing quality can be guaranteed.

Of course, if the defrosting completion time when the defrosting module is turned on with the best defrosting power at the current time is later than or equal to the expected home arrival time, it is obtained that the defrosting module is turned on at the current time and the expected home arrival time is the defrosting completion time. The preferred thawing power corresponding to the time is used to turn on the thawing module with the preferred thawing power. In this way, the best thawing quality can be provided while ensuring the thawing time effect.

Further, in an embodiment of the present invention, the step of "controlling the opening time of the defrosting module and its corresponding defrosting power according to the estimated time of arrival at home" includes:

Turn on the thawing module, calculate the preferred thawing power when the predicted arrival time is the thawing completion time, and adjust the thawing power in real time according to changes in the predicted arrival time.

Specifically, after the defrosting is turned on, the defrosting power can be calculated and controlled in real time according to the estimated arrival time. For example, due to changes in road conditions and other circumstances, the estimated time to arrive at home is shortened, the defrosting power can be increased according to the estimated time of arriving at home, and the defrosting power can be reduced if the estimated time to arrive at home increases. In this way, the thawing power is adjusted in real time according to the latest location information, the thawing quality is improved, and the user experience is prevented from interference caused by emergencies.

As a specific example, the refrigerator 100 is in communication with a smart phone, the user puts beef into the interior of the defrosting room in the morning, and the refrigerator recognizes that the food put in by the user is beef. If the user does not manually turn on the thawing, the thawing room will be operated in the freezing mode and start to receive the geographic location information sent by the smartphone, and form the moving route and average moving speed based on the multiple geographic location information of the mobile terminal, and according to the real-time location sent by the smartphone Plan the user's home route in real time through the map.

If the distance between the geographic location sent by the smartphone and the geographic location of home increases or the user's moving route does not coincide with the home route, it is determined that the user is not going home at this time and continues to operate the defrosting compartment in the freezing mode, otherwise, It is determined that the user is on the way home. When it is determined that the user is on the way home, the speed of walking, cycling, motor vehicle, etc. is retrieved from the cloud and compared with the average moving speed of the smartphone. If the average moving speed calculated at this time is similar to the speed of the motor vehicle, it is preliminarily determined that the user's travel mode is self-driving or taking a bus. At this time, further obtain the bus information from the geographic location of the smartphone to the geographic location of the home, specifically including the bus route and the real-time start and stop status of the bus, and compare the mobile route and start and stop information of the smartphone with the information of the bus, if the same It is determined that the user's travel mode is by bus, otherwise, it is determined that the user's travel mode is self-driving.

After obtaining the travel mode of the user, the selected home route is further determined. If the travel mode is by bus, the bus route is the selected home route. If the travel mode is self-driving, the home route that coincides with the travel route and is suitable for self-driving is marked as the selected home route. After confirming the selected home route, further obtain the road condition information of the selected home route, and calculate the earliest estimated time to arrive home.

If the user’s estimated home arrival time is 40 minutes later, 30 minutes is required for the beef to be thawed with the best defrosting power in the database, and then the best defrosting power will be used to defrost the beef when the estimated home arrival time is 30 minutes later. ; If the user’s expected home time is 20 minutes later, query the database for the preferred thawing power corresponding to the thawing completion time of 20 minutes, and control the thawing module to run at the preferred thawing power.

When the unfreezing module is turned on, it continues to obtain the location information sent by the smartphone, and calculates the estimated time to arrive home. If it is found that the road conditions are deteriorating and the user’s expected home time is extended, reduce the defrosting power; if it is found that the moving route deviates from the home route or the user’s location is far from the home location, it is determined that the user may have an emergency, and the defrosting is stopped at this time , And run in freezing mode again.

In this way, the defrosting opening time is controlled according to the user's expected arrival time to ensure that the user can use the food when he arrives home, and at the same time, the defrosting power is selected according to the defrosting time, and the quality of the food can be guaranteed.
