The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.
In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a refrigerator 100 according to an embodiment of the present invention, where the refrigerator 100 according to the embodiment of the present invention includes a refrigerator body 10, a shelf 20, a weight sensor 30, and a controller 40. A chamber is provided in the cabinet 10, wherein the chamber includes a component storage chamber for storing components in the refrigerator, such as a compressor, and a storage compartment for storing food, etc. The storage compartments may be configured as a refrigerating compartment, a freezing compartment, and a temperature-changing compartment (also called a fresh-keeping compartment), depending on the purpose. One or more door bodies are corresponding to each storage compartment, for example, in fig. 1, the storage compartment at the upper part is provided with a double-opening door body, wherein the door body can be pivotally arranged at the opening of the box body and can also be opened in a drawer mode to realize drawer type storage. The shelf 20 is detachably disposed in the storage compartment, and is used for dividing the storage compartment into a plurality of storage spaces. The weight sensor 30 is disposed on each of the shelves 20 for detecting the weight of the shelf 20. The controller 40 is configured to obtain the weight of the weight sensor 30 and analyze the weight to determine whether the user has a storage space in the storage compartment, and then send a prompt to remind the user when the user has no storage space in the storage compartment.
The weight sensor 30 is a strain gauge load cell consisting of a solid metal body (or "spring element") that holds a strain gauge. The body of the weight sensor 30 is slightly deformed and deflected when a load is applied. Deflection means that the load cell varies along the length of the main shaft when a load is applied. In a pull-press weight sensor, deflection makes the gauge shorter and thicker. In the tension weight sensor, the meter is stretched and becomes long and thin. The strain gage also changes shape in response to changes in body shape. This in turn causes a change in the resistance of the strain gauge, which can then be measured as a change in voltage. Since this change in output is proportional to the amount of weight applied, the weight of the object can be determined from the change in voltage.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a refrigeration system in a refrigerator 100 according to an embodiment of the present invention, where the refrigeration system includes a compressor 1, a condenser 2, a condensation preventing pipe 3, a drying filter 4, a capillary tube 5, an evaporator 6, and a gas-liquid separator 7. The working process of the refrigeration system comprises a compression process, a condensation process, a throttling process and an evaporation process. Wherein, the compression process is as follows: the power line of the refrigerator is plugged, when the contact of the temperature controller is connected, the compressor 1 starts to work, the low-temperature and low-pressure refrigerant is sucked by the compressor 1, and is compressed into high-temperature and high-pressure superheated gas in the cylinder of the compressor 1 and then is discharged into the condenser 2; the condensation process is as follows: the high-temperature and high-pressure refrigerant gas is radiated by the condenser 2, the temperature is continuously reduced, the refrigerant gas is gradually cooled into normal-temperature and high-pressure saturated vapor and further cooled into saturated liquid, the temperature is not reduced any more, the temperature at the moment is called as the condensation temperature, and the pressure of the refrigerant in the whole condensation process is almost unchanged; the throttling process is as follows: the condensed refrigerant saturated liquid flows into the capillary tube 5 after moisture and impurities are filtered by the drying filter 4, throttling and pressure reduction are carried out through the capillary tube, and the refrigerant is changed into normal-temperature low-pressure wet vapor; the evaporation process is as follows: the normal temperature and low pressure wet steam starts to absorb heat for vaporization in the evaporator 6, which not only reduces the temperature of the evaporator and the surrounding, but also changes the refrigerant into low temperature and low pressure gas, the refrigerant from the evaporator 6 returns to the compressor 1 after passing through the gas-liquid separator 7, and the processes are repeated to transfer the heat in the refrigerator to the air outside the refrigerator, thereby realizing the purpose of refrigeration.
Referring to fig. 3, fig. 3 is a schematic view of an installation position of a refrigeration fan 8 in a refrigerator 100 according to an embodiment of the present invention, where the refrigeration fan 8 continuously enters air into fins of the evaporator 6 for heat exchange, and sends air that has been cooled by heat release of the evaporator 6 to the refrigerating chamber and the freezing chamber through an air duct, so that the air in the storage chamber continuously circulates and the temperature is reduced.
The controller 40 is configured to obtain the weight of each shelf in the current storage compartment after detecting that the door is opened, and determine that the food material in the current storage compartment is unreasonably distributed when the weight of any shelf is greater than a weight threshold; calculating the weight difference value between the current shelf and the rest shelves, if any weight difference value is larger than the weight difference threshold value, determining the shelf with the weight difference value larger than the weight difference threshold value as a first target shelf, and sending first prompt information; the first prompt message is used for reminding a user of placing part of food materials on the current shelf on a first target shelf. And when the weight of all the shelves is less than or equal to the weight threshold, judging that the food material in the current storage compartment is reasonably distributed, and not sending out prompt information.
The controller 40 is further configured to: if the weight difference values are smaller than or equal to the weight difference threshold value, acquiring the weight of each shelf in another storage compartment, and sending a second prompt message when a second target shelf with a weight difference value larger than the weight difference threshold value exists in the other storage compartment; the second prompt message is used for reminding a user of placing part of food materials on the current shelf on the second target shelf.

and S11, judging whether the door opening operation is detected, if so, entering the step S12, and if not, returning to the step S11.
S12, when the door opening operation is detected, the weight of each shelf in the current storage compartment is acquired, and then step S13 is performed.
When the door opening operation is detected, it is indicated that the user may need to place food materials into the refrigerator at the moment, and at the moment, the weight borne by the shelf detected by the weight sensor in each shelf is obtained, and the weight can reflect how many food materials are placed on the current shelf. It should be noted that the weight detection process can be performed from the time the user opens the door to the time the door is closed, and the weight of each shelf is monitored in real time during the process.
S13, judging whether the weight of any shelf is larger than the weight threshold value, if so, going to step S14, and if not, going to step S20.
S14, when the weight of any shelf is larger than the weight threshold value, the food material in the current storage compartment is judged to be unreasonably distributed, and then the process goes to step S15.
The weight threshold is preset, the weight of a certain fruit on one shelf can be used as the weight threshold, and when the weight of any shelf is larger than the weight threshold, the situation that food materials are placed on the shelf too much and a food stacking phenomenon may occur is shown.
S15, calculating the weight difference value between the current shelf and the rest shelves, and then entering the step S16.
When the food materials placed on the current shelf are larger than the weight threshold value, the weights of the rest shelves are further judged so as to determine the weight of the food materials stored in the rest shelves.
And S16, judging whether any weight difference value is larger than a weight difference threshold value, if so, entering a step S17, and if not, entering a step S18.
S17, if any weight difference value is larger than the weight difference threshold value, determining the shelf with the weight difference value larger than the weight difference threshold value with the current shelf as a first target shelf, and sending a first prompt message.

If the weight difference values are all smaller than or equal to the weight difference threshold value, it is indicated that a large number of food materials are stored in each shelf in the current storage compartment (such as a refrigerating compartment), at this time, if the food materials on the overweight shelf are transferred to another shelf, an overweight phenomenon may occur on another shelf, and at this time, the storage conditions of the food materials in the other storage compartments (such as a temperature-changing compartment) can be obtained.
And S19, when a second target shelf with a weight difference value larger than the weight difference threshold exists in the other storage room, sending out a second prompt message.
The weight difference between the second target shelf and the current shelf is large, and prompt information can be sent to enable a user to transfer food materials on the current shelf to the second target shelf. If there is no second target shelf in the other storage compartment, and thus the refrigerator stores a lot of food materials, the user is given the option to place the food materials to any position.
And S20, when the weights of all the shelves are less than or equal to the weight threshold, judging that the food material in the current storage compartment is reasonably distributed, and not sending out prompt information.
In the embodiment of the invention, when a user places food materials into shelves, the weight of each shelf in the same storage compartment is detected, when the food materials are unreasonably distributed on the shelves, the shelves belonging to the same storage compartment are recommended to the user, the user can replace the food materials according to the prompt information, if the food materials placed in the shelves of the same storage compartment are more, the shelves of another storage compartment are recommended to the user, the phenomenon of stacking the food materials on the premise that the refrigerator stores less food materials is avoided, the food materials are quickly refrigerated in the compartments, the preservation effect is improved, and the user can conveniently and quickly find the required food materials.

S23, when the number of the target placement areas with the detected local weight values is larger than or equal to a preset contact number threshold value, judging that the food materials in the current shelf are reasonably distributed, and not sending out prompt information;
and S24, when the number of the target placement areas with the local weight values is detected to be smaller than the contact number threshold value, judging that the distribution of the food materials in the current shelf is unreasonable, and sending a third prompt message.
Specifically, referring to fig. 6, fig. 6 is a schematic distribution diagram of the weight sensors in the layer rack provided by the embodiment of the present invention, and the bottom of each layer rack 20 is divided into a plurality of placement areas, such as a 1-a 6, B1-B6, C1-C6, D1-D6, and E1-E6 shown in fig. 7. It should be noted that, in practical applications, the thawing area may be divided according to the area of the shelf 20, and is not limited to 30, and may also be 20, 30, and the like, and the present invention is not limited thereto.
When the weight of any shelf is smaller than or equal to the weight threshold and larger than the preset lowest threshold, the lowest threshold is smaller than the weight threshold, which indicates that the food materials on the shelf are not too much (too much prompts a user to place part of the food materials on other shelves) and not too little (too little does not cause the stacking phenomenon of the food materials), but in order to avoid the stacking phenomenon of the food materials on the shelf, whether the food materials on the current shelf are stacked or not is determined by using the local weight of each placement area. When the weight of the food materials placed on the current shelf is heavy (obtained by accumulating the local weight of each placing area), the contact placing areas are also more, so that the contact quantity threshold value corresponding to the shelf can be obtained by calculation according to the weight of the shelf. For example, when the threshold of the number of contacts corresponding to the shelf is 6, fig. 8 is a schematic diagram of a case where the contact range between the food material and the shelf is large, and at this time, the food material contacts the shelf more, and the stacking phenomenon does not occur, and fig. 9 is a schematic diagram of a case where the contact range between the food material and the shelf is small, and at this time, the contact between the food material and the shelf is less, and the stacking phenomenon may occur, and a prompt message is sent to prompt a user.
The prompt messages (the first prompt message, the second prompt message and the third prompt message) in the embodiment of the invention can be prompted once, and a user can operate according to the prompt messages or can not take care of the prompt messages, wherein the prompt messages are voice prompt messages.
Optionally, after sending the first prompt message, the controller 40 is further configured to: after the first prompt message is sent, if the weight of the current shelf is detected to be larger than the weight threshold value after a set time period, the rotating speed of the refrigerating fan is increased within a preset rotating speed adjusting range, and after the preset adjusting time period is reached, the rotating speed of the refrigerating fan is restored to the initial rotating speed.
Exemplarily, referring to fig. 10, fig. 10 is a third flowchart of the controller of the refrigerator according to the embodiment of the present invention, where the controller 40 is configured to execute steps S171 to S174:
and S171, detecting whether the weight of the current shelf is greater than a weight threshold value after a set time period, if so, entering a step S172, and if not, ending the judging process.
And S172, when the weight of the current shelf is detected to be larger than the weight threshold value after the set time period, increasing the rotating speed of the refrigerating fan within a preset rotating speed adjusting range, and then entering the step S173.
And S173, judging whether the operation time of the refrigeration fan reaches a preset adjustment time, if so, entering a step S174, and if not, repeatedly executing the step S173.
And S174, controlling the refrigerating fan to recover to the initial rotating speed when the running time of the refrigerating fan reaches the adjusting time.
The set time period can be 1min, if it is detected that the weight of the current shelf (overweight shelf) is still larger than the weight threshold value in 1min, the fact that a user still does not place food materials of the current shelf on other shelves after the prompt message is sent indicates that the user still does not place the food materials on the shelf, at the moment, the rotating speed of the refrigerating fan is adjusted within an adjustable range in order to enable the food materials to reach the target temperature quickly, the rotating speed of the refrigerating fan is increased to achieve quick refrigeration, the shortest time is reduced to the target temperature to the greatest extent, the adjusting time can be 5min, the adjusting time is not suitable to be too long, the phenomenon that the food materials are frozen out due to too low temperature of a storage chamber is avoided, and the rotating speed of the refrigerating fan is restored to the initial rotating speed after the adjusting time is reached.
Referring to fig. 11, fig. 11 is a schematic diagram of interaction between a refrigerator 100 and a client 200 according to an embodiment of the present invention, where the refrigerator 100 establishes a data connection with the client 200 through a router 300 or a cloud server 400. When the refrigerator 100 and the client 200 communicate with each other through the router 300, the refrigerator 100 and the client 200 are located at a short distance, and a user can view an operation condition or a food storage condition of the refrigerator placed in a kitchen in a living room or a room. When the refrigerator 100 and the client 200 communicate with each other through the cloud server 400, the refrigerator 100 and the client 200 are far away from each other, and a user can perform data interaction with the refrigerator 100 through the APP installed in the client 200, and can also realize remote control of the refrigerator 100.
Compared with the prior art, in the refrigerator 100 disclosed in the embodiment of the invention, the weight sensors are arranged in the shelves of the refrigerator storage chamber to monitor the weight of each shelf, after the user opens the door for a period of time, whether the user reasonably places food materials in the current storage chamber is judged based on the detected weight value of each shelf, if the weight of any shelf is greater than the weight threshold value, the food materials in the current storage chamber are judged to be unreasonably distributed, the user needs to be prompted to place the food materials in the shelf in other shelves, the food materials in the shelf are prevented from being stacked, and meanwhile, the rest of vacant space is reasonably utilized. According to the embodiment of the invention, the food material stacking phenomenon can be avoided on the premise that the refrigerator stores less food materials, so that the food materials are quickly refrigerated in the compartment, the fresh-keeping effect is improved, and a user can conveniently and quickly find the required food materials.
Referring to fig. 12, fig. 12 is a flowchart of a refrigerator food material distribution method according to an embodiment of the present invention, where the refrigerator food material distribution method is implemented by a controller in a refrigerator, and a weight sensor is disposed on each shelf in the refrigerator, the refrigerator food material distribution method includes steps S1 to S3:
s1, acquiring the weight of each shelf in the current storage compartment after detecting the opening operation of the door; wherein, each layer of shelf is provided with a weight sensor;
s2, when the weight of any shelf is larger than the weight threshold value, judging that the food material distribution in the current storage compartment is unreasonable;
s3, calculating the weight difference value between the current shelf and the rest shelves, if any weight difference value is larger than the weight difference threshold value, determining the shelf with the weight difference value larger than the weight difference threshold value as a first target shelf, and sending out first prompt information; the first prompt message is used for reminding a user of placing part of food materials on the current shelf on a first target shelf;
s4, if the weight difference values are all smaller than or equal to the weight difference threshold value, acquiring the weight of each shelf in another storage compartment, and when a second target shelf with a weight difference value larger than the weight difference threshold value exists in the other storage compartment, sending out second prompt information; the second prompt message is used for reminding a user of placing part of food materials on the current shelf on the second target shelf.
Specifically, in step S1, when the door opening operation is detected, it indicates that the user may need to place food into the refrigerator at this time, and at this time, the weight carried by the shelves detected by the weight sensor in each of the shelves is obtained, and this weight may reflect how much food is placed on the current shelf. It is worth noting that the weight detection process can be performed from the time the user opens the door to the time the user closes the door, and the weight of each shelf is monitored in real time during the process.
Specifically, in step S2, the weight threshold is preset, and the weight of a certain fruit on one shelf may be used as the weight threshold, and when the weight of any shelf is greater than the weight threshold, it indicates that too much food is placed on the shelf, and a food stacking phenomenon may occur. And when the weights of all the shelves are less than or equal to the weight threshold, judging that the food materials in the current storage compartment are reasonably distributed, and not sending out prompt information.
Specifically, in step S3, when the food material placed in the current shelf is greater than the weight threshold, the weights of the remaining shelves are further determined to determine the weights of the food materials stored in the remaining shelves. The weight difference between the first target shelf and the current shelf is large, and prompt information can be sent to enable a user to transfer food materials on the current shelf to the first target shelf.
Specifically, in step S4, if the weight difference values are all less than or equal to the weight difference threshold value, it indicates that there are many food materials stored in each shelf in the current storage compartment (e.g., the refrigerating compartment), and if the food material in the overweight shelf is transferred to another shelf, an overweight phenomenon may occur in another shelf, and at this time, the storage conditions of the food materials in the remaining storage compartments (e.g., the temperature-changing compartment) may be obtained. The weight difference between the second target shelf and the current shelf is large, and prompt information can be sent to enable a user to transfer food materials on the current shelf to the second target shelf. If the second target shelf does not exist in the other storage compartment, and therefore the refrigerator stores a lot of food materials, the user can place the food materials to any position.
In the embodiment of the invention, when a user places food materials into shelves, the weight of each shelf in the same storage compartment is detected, when the food materials are unreasonably distributed on the shelves, the shelves belonging to the same storage compartment are recommended to the user, the user can replace the food materials according to the prompt information, if the food materials placed in the shelves of the same storage compartment are more, the shelves of another storage compartment are recommended to the user, the phenomenon of stacking the food materials on the premise that the refrigerator stores less food materials is avoided, the food materials are quickly refrigerated in the compartments, the preservation effect is improved, and the user can conveniently and quickly find the required food materials.
Specifically, the bottom of each shelf is divided into a plurality of placing areas, and each placing area is provided with a weight sensor; then, the refrigerator food material distribution method further comprises:
when the weight of any shelf is smaller than or equal to the weight threshold and larger than a preset lowest threshold, acquiring a local weight value detected by a weight sensor in each placement area in the current shelf;
when the number of the target placing areas of the local weight value is detected to be larger than or equal to a preset contact number threshold value, judging that the food materials in the current shelf are reasonably distributed, and not sending prompt information; wherein the contact number threshold is determined by the weight of the current shelf, and the contact number threshold is in a direct proportion relation with the weight of the current shelf;
when the number of the target placement areas with the local weight value is smaller than the contact number threshold value, judging that the food materials in the current shelf are unreasonably distributed, and sending out third prompt information; and the third prompt information is used for reminding a user of uniformly placing the food materials on the current shelf.
For example, when the weight of any shelf is smaller than or equal to the weight threshold and larger than a preset minimum threshold, the minimum threshold is smaller than the weight threshold, which indicates that the food materials on the shelf are not too much (too much prompts the user to place part of the food materials on other shelves) and not too little (too little does not cause the stacking phenomenon of the food materials), but in order to avoid the stacking phenomenon of the food materials on the shelf, whether the food materials on the current shelf are stacked or not is determined by using the local weight of each placement area. When the weight of the food materials placed on the current shelf is heavy (obtained by accumulating the local weight of each placing area), the number of the contact placing areas is also large, so that the contact quantity threshold corresponding to the shelf can be obtained by calculation according to the weight of the shelf. For example, when the contact quantity threshold value corresponding to the layer frame is 6, when the contact range of the food material and the layer frame is large (the contact quantity is larger than 6), the contact of the food material and the layer frame is large, the stacking phenomenon cannot occur, when the contact range of the food material and the layer frame is small (the contact quantity is smaller than 6), the contact of the food material and the layer frame is small, the stacking phenomenon is likely to occur, and the prompt message is sent to remind the user.
The prompt messages (the first prompt message, the second prompt message and the third prompt message) in the embodiment of the invention are all prompted once, and the user can operate according to the prompt messages or can not be reckoned, wherein the prompt messages are voice prompt messages.
Optionally, after the first prompt message is sent out, the refrigerator food material distribution method further includes:
after the first prompt message is sent, if the weight of the current shelf is detected to be larger than the weight threshold value after a set time period, the rotating speed of the refrigerating fan is increased within a preset rotating speed adjusting range, and after the preset adjusting duration is reached, the rotating speed of the refrigerating fan is restored to the initial rotating speed.
For example, the set time period may be 1min, if it is detected that the weight of the current shelf (an overweight shelf) is still greater than the weight threshold in 1min, which indicates that a user still does not place food materials on the other shelves after sending a prompt message, at this time, in order to quickly reach a target temperature for the food materials, the rotation speed of the cooling fan is adjusted within an adjustable range to increase the rotation speed of the cooling fan to realize quick cooling, so as to meet the requirement that the shortest time is decreased to the target temperature as much as possible, the adjustment time period may be 5min, the adjustment time period is not too long, the phenomenon that the food materials are frozen due to too low temperature in a storage compartment is avoided, and after the adjustment time period is reached, the rotation speed of the cooling fan is restored to the initial rotation speed.
Further, the refrigerator establishes a data connection with the client through a router or a cloud server. When the refrigerator and the client communicate through the router, the refrigerator and the client are close to each other, and a user can check the operation condition or food storage condition of the refrigerator placed in a kitchen in a living room or a room. When the refrigerator and the client communicate through the cloud server, the refrigerator and the client are far away from each other, a user can perform data interaction on the APP installed in the client and the refrigerator, and meanwhile remote control of the refrigerator can be achieved.
Compared with the prior art, the refrigerator food material distribution method disclosed by the embodiment of the invention has the advantages that the weight sensors are arranged in the shelves of the refrigerator storage chamber to monitor the weight of each shelf, after a user opens the door for a period of time, whether the user reasonably places food materials in the current storage chamber is judged based on the detected weight value of each shelf, if the weight of any shelf is larger than the weight threshold value, the food material distribution in the current storage chamber is judged to be unreasonable, the user needs to be prompted to place the food materials in the shelf in other shelves, the food materials in the shelf are prevented from being stacked, and meanwhile, the rest of vacant space is reasonably utilized. According to the embodiment of the invention, the food material stacking phenomenon can be avoided on the premise that the refrigerator stores fewer food materials, so that the food materials are quickly refrigerated in the compartment, the fresh-keeping effect is improved, and a user can conveniently and quickly find the required food materials.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
