The specific meaning of the above terms in the present application will be understood in specific cases 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 includes a refrigeration system for powering a refrigeration cycle of the refrigerator, auxiliary devices (such as lighting, communication, temperature detection, humidity detection, etc.) for providing auxiliary functions to the refrigerator, and a controller for controlling a refrigeration operation and other auxiliary functions of the refrigerator.

Referring to fig. 2, fig. 2 is a schematic diagram of a refrigeration system in a refrigerator 100 according to an embodiment of the present invention, the refrigeration system including a compressor 1, a condenser 2, an anti-condensation pipe 3, a dry filter 4, a capillary tube 5, an evaporator 6, and a gas-liquid separator 7. The working processes of the refrigeration system comprise a compression process, a condensation process, a throttling process and an evaporation process.

The compression process comprises the following steps: when the power line of the refrigerator is inserted and 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, compressed into high-temperature and high-pressure overheat gas in the cylinder of the compressor 1 and then discharged to the condenser 2; the condensation process is as follows: the high-temperature and high-pressure refrigerant gas radiates heat through the condenser 2, the temperature is continuously reduced, the refrigerant gas is gradually cooled into normal-temperature and high-pressure saturated steam, the saturated steam is further cooled into saturated liquid, the temperature is not reduced any more, the temperature at the moment is called as condensing temperature, and the pressure of the refrigerant in the whole condensing process is almost unchanged; the throttling process is as follows: the condensed refrigerant saturated liquid is filtered by a dry filter 4 to remove moisture and impurities, and then flows into a capillary tube 5, throttling and depressurization are carried out through the capillary tube, and the refrigerant is changed into normal-temperature and low-pressure wet vapor; the evaporation process is as follows: the wet vapor with normal temperature and low pressure starts to absorb heat in the evaporator 6 for vaporization, so that the temperature of the evaporator and the surrounding temperature are reduced, the refrigerant is changed into low-temperature and low-pressure gas, the refrigerant coming out of the evaporator 6 returns to the compressor 1 again after passing through the gas-liquid separator 7, the process is repeated, and the heat in the refrigerator is transferred into the air outside the refrigerator, so that the purpose of refrigeration is realized.

Referring to fig. 3, fig. 3 is a schematic diagram of a position of a fan in a refrigerator according to an embodiment of the present invention, and fig. 3 shows a side surface of the refrigerator 100, where the fan 8 is configured to convey cold air flowing out of the evaporator 6 after heat exchange, and convey the cold air into a refrigerating air duct and a freezing air duct, respectively, and then enter the refrigerating chamber and the freezing chamber through an air outlet of an air duct path.

Referring to fig. 4, the auxiliary devices include a light module (not shown), a display 9, a communication device 10, a temperature sensor 11, and a humidity sensor 12.

The light module is arranged in the compartment of the refrigerator 100, can be opened along with the opening of the compartment door body, and can be closed along with the closing of the compartment door body, the controller records the opening time and the closing time of the light module when detecting that the light module is opened, and simultaneously obtains the power consumption of the light module (such as the power consumption in 1 h) in a period of time measured in a laboratory.

The display 9 is turned on when the user needs to use the display, and the power consumption of the display 9 is fixed or approximately unchanged (mainly, the power consumption of the screen is high) in a period of time, so that when the controller detects that the display 9 is turned on, the turn-on duration of the display 9 is counted, and the turn-on duration is compared with the power consumption of the display 9 predicted in a laboratory in a period of time (such as the power consumption in 1 h), namely, a display-related user behavior power consumption model is constructed, and the real-time power consumption of the display 9 is obtained.

The communication device 10 is configured to communicate with the outside, for example, communicate with a client, the temperature sensor 11 and the humidity sensor 12 are both disposed outside the refrigerator 100, the temperature sensor 11 and the humidity sensor 12 are respectively configured to detect an ambient temperature and an ambient humidity of an indoor environment where the refrigerator 100 is located, and because the communication device 10, the temperature sensor 11 and the humidity sensor 12 are all in a long-time open state (kept in a start state when the refrigerator is in a power-on state), power consumption of the three devices in a period of time is fixed, but the power consumption of the three devices is irrelevant to the refrigerator refrigeration system and the user behavior, the power consumption calculation does not need to perform operation time matching of the devices, so that a model is not required to be constructed, and when the real-time power consumption is calculated, the real-time power consumption of the three devices can be obtained by obtaining the time of the power-on operation of the refrigerator.

Referring to fig. 5, fig. 5 is a schematic diagram illustrating 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 through the router 300, the refrigerator 100 and the client 200 are closely spaced, and a user can view the operation condition of the refrigerator or the storage condition of food materials placed in a kitchen in a living room or a room. When the refrigerator 100 and the client 200 communicate through the cloud server 400, the refrigerator 100 and the client 200 are far apart, and a user can perform data interaction with the refrigerator 100 through an APP installed in the client 200, and meanwhile, remote control of the refrigerator 100 can be realized.

Further, the controller reports the power consumption condition of the refrigerator to the cloud server 400 at intervals (for example, 2 h), the cloud server 400 establishes a data file of each refrigerator, provides power consumption using reports of the refrigerator in different modes such as daily, weekly, monthly, annual and the like for users, optimizes the power consumption of the refrigerator, reduces the energy consumption, provides a more energy-saving refrigerator using method for the users, optimizes the user experience while adding value to products, and simultaneously enables the users to check the power consumption condition of the refrigerator and the refrigerator using report on a local screen end of the refrigerator or a mobile phone APP daily, weekly, monthly and annual, so that the users can use the refrigerator more scientifically and energy-effectively.

Specifically, the controller is used for: after the refrigerator is electrified, acquiring operation parameters, environment parameters and user behaviors of the refrigerating system once every preset unit time; acquiring a corresponding refrigeration power consumption model according to the environmental parameters, and acquiring the corresponding refrigeration power consumption in unit time in the refrigeration power consumption model based on the operation parameters; acquiring corresponding user behavior power consumption in unit time in a user behavior power consumption model based on the user behavior, and acquiring conventional power consumption in the unit time; and accumulating the refrigeration power consumption, the user behavior power consumption and the conventional power consumption in unit time to obtain real-time power consumption.

Referring to fig. 6, fig. 6 is a flowchart of calculating real-time power consumption by the refrigerator controller according to the embodiment of the present invention, and the controller executes steps S101 to S108:

S101, after the refrigerator is powered on, acquiring operation parameters, environment parameters and user behaviors of the refrigerating system once every preset unit time.

The operation parameters can comprise parameters such as temperature of each compartment of the refrigerator, a mode set by the refrigerator, frequency of a compressor, power of a heating wire, power of a fan and the like, the environment parameters comprise environment temperature and environment humidity, and the user behaviors comprise user touch display behaviors and user compartment door opening behaviors; the unit time may be 1h.

S102, acquiring a corresponding refrigeration power consumption model according to the environmental parameters.

For example, the refrigeration power consumption model may be stored in a cloud server, and the refrigeration power consumption is power consumption of the refrigeration system. The controller firstly needs to upload the refrigerator model information of the controller to the cloud server before executing the step S102, the cloud server matches the corresponding electric quantity calculation data model library of the refrigerator with the model according to the uploaded refrigerator model information, different refrigerator models correspond to different electric quantity calculation data model libraries, the power consumption models corresponding to the refrigerators with the same model can be concentrated in one database, the models required by the refrigerators with the current model can be quickly obtained in a large number of models and sent to the corresponding refrigerators, and meanwhile, the models are obtained once in unit time, so that the models are prevented from being updated and failing to follow in time. And then the controller uploads the environmental parameters, and the cloud server transmits the corresponding refrigeration power consumption model to the refrigerator according to the uploaded environmental parameters.

S103, acquiring the corresponding refrigeration power consumption in unit time in the refrigeration power consumption model based on the operation parameters.

The refrigeration power consumption model comprises a plurality of models divided by different environment temperatures and environment humidity, and each refrigeration power consumption model records a plurality of refrigeration parameter indexes and refrigeration power consumption in unit time corresponding to the refrigeration parameter indexes; wherein, each operation parameter of the refrigeration system has a corresponding refrigeration parameter index. Corresponding temperature and humidity characteristic databases are established in the model library according to refrigerators of different models, for example, the temperature range is-50 ℃ and the humidity is 0-100%, the two data of the ambient temperature and the ambient humidity are taken as refrigeration index data, each group of data corresponds to a refrigeration index table, for example, the ambient temperature is 1 ℃ and the ambient humidity is 10% as a group of refrigeration index data, and each refrigeration index table is recorded with the corresponding power consumption per unit time when the operation parameters of power consumption devices in different refrigeration systems are in different values. Temperature parameters of refrigerator compartment: refrigerating at 2-8 deg.c, freezing at-25 to-15 deg.c and varying temperature at-20-5 deg.c. For each load, for example: the compressor frequency is respectively in different states of 20, 40, 50, 60, 75, 80, 100, 130, 140, 150MHz and the like, and the power model library can be built for the fan according to different actual set rotating speeds.

When the refrigerator is electrified, the parameter value of the current state of the refrigerating system and the refrigerating power consumption model are matched at intervals, and then a matching power model library of each load in the current state is obtained. If the current setting state of the refrigerator changes, for example, the frequency of the compressor is changed from 100MHz to 150MHz (the running parameter is obtained once every unit time, so that the change of the frequency of the compressor can be monitored), the other power consumption device parameters are unchanged, at the moment, the index is carried out again to obtain the power consumption corresponding to the compressor with the changed power value, for example, the unit time is 1h, the compressor is maintained at the rotating speed of 100MHz in the first 1 hour, the refrigerating power consumption corresponding to the unit time is obtained at the moment, if the compressor is maintained at the rotating speed of 150MHz in the last 1 hour, at the moment, the corresponding refrigerating power consumption in the unit time is found according to the parameters of the other power consumption devices such as the rotating speed of the compressor, the rotating speed of the fan and the like in the last 1 hour.

In the embodiment of the invention, the environmental temperature and humidity values stored in the refrigerator are unpredictable, and the system can query the environmental parameters every other unit time so as to match the model library of the corresponding environmental temperature and humidity. The method comprises the steps that test inclusion is carried out on each set parameter condition of the running state of the refrigerator in advance, the conditions contained in the model library are enough to contain the actual running state of the refrigerator, and for special conditions such as the load of after-sales personnel for replacing the model of the refrigerator by mistake or the state loss of the model library caused by negligence, the refrigerator can actively report the fault to a cloud end and carry out relevant information prompt on a display device and a mobile phone end of the refrigerator, and the cloud end can continuously carry out optimization updating of the electric quantity model library according to the actual conditions.

S104, judging whether user behaviors exist, if yes, proceeding to step S105, otherwise proceeding to step S106.

S105, when the user behavior exists in the unit time, the corresponding user behavior power consumption in the unit time is obtained in a user behavior power consumption model based on the user behavior.

The power consumption of the user behavior is the power consumption of the light module and the display, and the power consumption model of the user behavior records a plurality of refrigerating door opening time periods and the corresponding power consumption of the user behavior in unit time, and records a plurality of display starting time periods and the corresponding power consumption of the user behavior in unit time.

S106, when no user behavior exists in the unit time, the power consumption of the user behavior is 0. When no user behavior exists, the display and the light module are not started at the moment, and the power consumption of the two devices in unit time is 0.

S107, acquiring the conventional power consumption in the unit time; the regular power consumption is power consumption of the communication device, the temperature sensor and the humidity sensor.

S108, accumulating the refrigerating power consumption, the user behavior power consumption and the conventional power consumption in unit time to obtain real-time power consumption.

Specifically, the controller is further configured to: when a power consumption inquiry command sent by the display is received, acquiring an inquiry time period written in the power consumption inquiry command, acquiring corresponding target refrigeration power consumption, target user behavior power consumption and target conventional power consumption in unit time according to the inquiry time period, and accumulating the target refrigeration power consumption, the target user behavior power consumption and the target conventional power consumption to obtain target power consumption.

Referring to fig. 7, fig. 7 is a flowchart of a refrigerator controller according to an embodiment of the present invention for querying power consumption for a specific period, where the controller is further configured to execute steps S109 to S112:

S109, detecting whether a power consumption inquiry command is received, if yes, proceeding to step S110, otherwise, re-executing step 109. The user can input the power consumption inquiry command on the display or remotely send the power consumption inquiry command through the client.

S110, when a power consumption inquiry instruction sent by the display is received, acquiring an inquiry time period written in the power consumption inquiry instruction. For example, the user needs to inquire about the power consumption in a week, at this time, the user can input the start time and the end time to be inquired in the display, the display writes the two times into the power consumption inquiry command, and the controller obtains the two times as inquiry basis when receiving the power consumption inquiry command.

S111, acquiring corresponding target refrigeration power consumption, target user behavior power consumption and target conventional power consumption in unit time according to the query time period. After the controller calculates the power consumption in a unit time, the power consumption is stored, so that the subsequent calculation is convenient.

And S112, accumulating the target refrigeration power consumption, the target user behavior power consumption and the target conventional power consumption to obtain target power consumption.

Specifically, the controller is further configured to: and comparing the current period power consumption in the current period with the historical period power consumption in the historical period every interval preset period to obtain an abnormality judgment result of the current period power consumption, and sending out early warning prompt information when the abnormality judgment result is abnormal.

Referring to fig. 8, fig. 8 is a flowchart of the refrigerator controller according to the embodiment of the present invention for determining abnormal power consumption, where the controller is further configured to execute steps S113 to S118:

S113, acquiring the running period of the refrigerator. For example, one operation cycle is 7 days, from monday to sunday as one operation cycle.

S114, judging whether the current operation period is separated from the previous operation period by one period, if so, entering a step S115, and if not, repeatedly executing the step S114.

S115, comparing the current period power consumption in the new running period with the historical period power consumption in the historical period every preset period. The power consumption of the refrigerator in one operation period is not greatly different due to the habit of a user, so that the new period is compared with the history period, whether the power consumption of the new period is abnormal or not can be judged, and the abnormality indicates that some devices possibly have faults.

S116, obtaining an abnormality judgment result of the current period power consumption. When the controller detects that the power consumption of a certain day is abnormally large or abnormally small, the controller can evaluate related faults.

S117, judging whether the abnormality judgment result is abnormal; if yes, go to step S118, if not, re-execute step S117.

And S118, when the abnormality judgment result is abnormal, sending out early warning prompt information. The early warning prompt information can be sent to a user client through the controller, for example, the early warning prompt information is sent in a short message mode, so that a user is reminded of whether the refrigerator has faults or not.

Further, the operation parameters comprise a plurality of sub-parameters corresponding to power consumption devices in the refrigeration system; and obtaining the refrigeration power consumption corresponding to the unit time in the refrigeration power consumption model based on the operation parameters, wherein the method comprises the following steps:

When each sub-parameter can find out the corresponding refrigeration parameter index equal to the value thereof in the refrigeration power consumption model, acquiring the corresponding refrigeration power consumption according to the refrigeration parameter index;

when any subparameter does not find the corresponding refrigeration parameter index equal to the numerical value thereof in the refrigeration power consumption model, parameter correction in a preset range is carried out on the subparameter, and the refrigeration parameter index equal to the numerical value thereof is found in the refrigeration power consumption model according to the corrected subparameter and other subparameters, and the corresponding refrigeration power consumption is obtained.

Referring to fig. 9, fig. 9 is a flowchart of obtaining refrigeration power consumption by the refrigerator controller according to the embodiment of the present invention, where the controller is further configured to perform steps S119 to S123:

S119, obtaining sub-parameters corresponding to power consumption devices in the refrigeration system;

S120, judging whether each sub-parameter can find the corresponding refrigeration parameter index equal to the value of the sub-parameter in the refrigeration power consumption model, if so, executing the step S123, and if not, executing the step S121.

S121, when any sub-parameter exists, and a corresponding refrigeration parameter index equal to the value of the sub-parameter cannot be found in the refrigeration power consumption model, carrying out parameter correction within a preset range on the sub-parameter.

For example, in the embodiment of the invention, parameters of the refrigerator are set in various states, such as temperature, humidity and power of different frequencies of the compressor, of each compartment, and each state is completely controlled by the refrigerator control system and is contained in the model library. For the actual environment stored in the refrigerator, in the data matching process, there may be a situation that part of parameters cannot correspond to model indexes, and there is a partial deviation, for example, the environment parameters corresponding to the models are temperature 20 and humidity 30, at this time, the corresponding models cannot be queried for the power consumption per unit time when the rotation speed of the compressor is x1, the rotation speed of the fan can be queried, at this time, the situation that the model library cannot be matched already appears is indicated, the controller can match the parameters when the power of the compressor is x2 (the data in the index table with the nearest value of x 1) by adopting a nearby consistent principle, then revises the rotation speed x1 into x2 for re-indexing, namely, the follow-up matching is carried out by modifying the condition of the subparameters, meanwhile, the situation can be uploaded to the cloud at the same time, the cloud can judge whether the abnormal condition appearing in the cloud needs to be processed independently according to the actual situation, if the abnormal condition is true, the update of the model library can be fed back to the laboratory for follow-up measurement, and then the staff updates the model library corresponding to the parameter.

S122, searching a refrigeration parameter index equal to the value of the refrigeration power consumption model according to the corrected subparameter and the rest subparameter.

S123, obtaining corresponding refrigeration power consumption according to the refrigeration parameter index.

It should be noted that, since there are many parameters related to the cooling power consumption model, there may be some cases where some parameters are not recorded in the model library, so the parameter correction process in steps S121 to S122 is needed, but the parameters related to the user behavior power consumption model are few (the time length and the power consumption correspondence relation) and therefore basically one index table can be included, so there may not be a case where the parameters cannot be corresponded (in practice, only the power consumption in unit time corresponding to different user behavior related devices need to be recorded in the table), and therefore correction of the parameter value may not be needed.

Compared with the prior art, the refrigerator disclosed by the embodiment of the invention has the advantages that a plurality of power consumption models are prestored in the refrigerator, in the actual operation of the refrigerator, the power consumption in a period of time is obtained by acquiring the operation state of the refrigerator in a period of time and then matching the operation state with the power consumption models prestored in the refrigerator, and finally the total power consumption is obtained by accumulating the power consumption in a historical period of time without complex calculation flow. Different power consumption devices in the refrigerator adopt different power consumption models, devices related to refrigeration adopt refrigeration power consumption models, devices related to user behaviors adopt user behavior power consumption models, and some conventional devices unrelated to refrigeration and user behaviors can directly use self fixed power consumption to accumulate because the power consumption of the conventional devices is unchanged, so that the counted power consumption of the refrigerator can accurately reflect the actual power consumption of the refrigerator. The refrigerator disclosed by the invention does not need to separately add a hardware electric quantity module to carry out electric quantity statistics of the refrigerator, and saves the space and the cost of the refrigerator.

Referring to fig. 10, fig. 10 is a flowchart of a method for monitoring power consumption of a refrigerator according to an embodiment of the present invention, where the method for monitoring power consumption of a refrigerator includes:

S1, after a refrigerator is powered on, acquiring operation parameters, environment parameters and user behaviors of a refrigerating system of the refrigerator once every preset unit time;

S2, acquiring a corresponding refrigeration power consumption model according to the environmental parameters, and acquiring the corresponding refrigeration power consumption in unit time in the refrigeration power consumption model based on the operation parameters; acquiring corresponding user behavior power consumption in unit time in a user behavior power consumption model based on the user behavior, and acquiring conventional power consumption in the unit time;

And S3, accumulating the refrigeration power consumption, the user behavior power consumption and the conventional power consumption in unit time to obtain real-time power consumption.

It should be noted that, the method for monitoring the power consumption of the refrigerator according to the embodiment of the invention is implemented by executing a controller in the refrigerator, and the refrigerator comprises a refrigerating system, an auxiliary device and a controller. The refrigerating system is used for providing power for refrigerating circulation of the refrigerator and comprises a compressor, an evaporator, a capillary tube, a condenser, a fan and an evaporator heating wire; the auxiliary device is used for providing auxiliary functions for the refrigerator and comprises a light module, a display, a communication device, a temperature sensor and a humidity sensor.

The light module is arranged in a compartment of the refrigerator, can be opened along with the opening of the compartment door body, and is closed along with the closing of the compartment door body, the controller records the opening time and the closing time of the light module when detecting that the light module is opened, and simultaneously obtains the power consumption (such as the power consumption in 1 h) of the light module in a period of time measured in a laboratory.

The display is turned on when the user needs to use the display, and the power consumption of the display is fixed or approximately unchanged (mainly, the power consumption of the screen is high) in a period of time, so that when the controller detects that the display is turned on, the turn-on duration of the display is counted, and the display is compared with the power consumption of the display predicted in a laboratory in a period of time (such as the power consumption in 1 h), namely, a user behavior power consumption model related to the display is constructed, and the real-time power consumption of the display is obtained.

The communication device is used for communicating with the outside, such as communicating with a client, the temperature sensor and the humidity sensor are both arranged outside the refrigerator body of the refrigerator, the temperature sensor and the humidity sensor are respectively used for detecting the ambient temperature and the ambient humidity of the indoor environment where the refrigerator is located, and the power consumption of the communication device, the temperature sensor and the humidity sensor in a long-time starting state (the starting state is kept when the refrigerator is in a power-on state) is fixed within a period of time, but the three devices are irrelevant to the refrigerating system of the refrigerator and the user behavior, the power consumption calculation of the three devices does not need to be matched with the operation time of the devices per se, so that a model is not required to be constructed, the power consumption of the three devices can be measured in advance in a laboratory, such as 1h power consumption xx, and the real-time power consumption of the three devices can be obtained by acquiring the power-on operation time of the refrigerator when the real-time power consumption is calculated.

Specifically, in step S1, the operation parameters may include parameters of temperature of each compartment of the refrigerator, a mode set by the refrigerator, frequency of the compressor, power of the heating wire, power of the fan, and the like, the environmental parameters include environmental temperature and environmental humidity, and the user behavior includes user touch display behavior and user compartment door opening behavior; the unit time may be 1h.

Specifically, in step S2, the refrigeration power consumption is the power consumption of the refrigeration system, the user behavior power consumption is the power consumption of the light module and the display, and the regular power consumption is the power consumption of the communication device, the temperature sensor and the humidity sensor.

For example, the refrigeration power consumption model and the user behavior power consumption model may be stored in a cloud server. The controller firstly needs to upload the refrigerator model information of the controller to the cloud server before uploading the environment parameters to the cloud server, the cloud server is matched with a corresponding electric quantity calculation data model base of the refrigerator of the model according to the uploaded refrigerator model information, different refrigerator models are corresponding to different electric quantity calculation data model bases, power consumption models corresponding to the refrigerators of the same model can be concentrated in one database, models required by the refrigerators of the current model can be quickly obtained in a large number of models and sent to the corresponding refrigerators, and meanwhile, a model is obtained once in unit time, so that the models are prevented from being updated and failing to follow in time. And then the controller uploads the environmental parameters, and the cloud server transmits the corresponding refrigeration power consumption model to the refrigerator according to the uploaded environmental parameters.

Specifically, the refrigeration power consumption model comprises a plurality of models divided by different environmental temperatures and environmental humidity, and each refrigeration power consumption model records a plurality of refrigeration parameter indexes and the refrigeration power consumption in the corresponding unit time; wherein, each operation parameter of the refrigeration system has a corresponding refrigeration parameter index.

For example, a corresponding temperature and humidity characteristic database is established in the model library according to refrigerators of different models, for example, the temperature range is-50 ℃ and the humidity is 0-100%, the two data of the ambient temperature and the ambient humidity are taken as refrigeration index data, each set of data corresponds to a refrigeration index table, for example, the ambient temperature is 1 ℃ and the ambient humidity is 10% as a set of refrigeration index data, and each refrigeration index table records the corresponding power consumption per unit time when the operation parameters of the power consumption devices in different refrigeration systems are in different values. Temperature parameters of refrigerator compartment: refrigerating at 2-8 deg.c, freezing at-25 to-15 deg.c and varying temperature at-20-5 deg.c. For each load, for example: the compressor frequency is respectively in different states of 20, 40, 50, 60, 75, 80, 100, 130, 140, 150MHz and the like, and the power model library can be built for the fan according to different actual set rotating speeds.

When the refrigerator is electrified, the parameter value of the current state of the refrigerating system and the refrigerating power consumption model are matched at intervals, and then a matching power model library of each load in the current state is obtained. If the current setting state of the refrigerator changes, for example, the frequency of the compressor is changed from 100MHz to 150MHz (the running parameter is obtained once every unit time, so that the change of the frequency of the compressor can be monitored), the other power consumption device parameters are unchanged, at the moment, the index is carried out again to obtain the power consumption corresponding to the compressor with the changed power value, for example, the unit time is 1h, the compressor is maintained at the rotating speed of 100MHz in the first 1 hour, the refrigerating power consumption corresponding to the unit time is obtained at the moment, if the compressor is maintained at the rotating speed of 150MHz in the last 1 hour, at the moment, the corresponding refrigerating power consumption in the unit time is found according to the parameters of the other power consumption devices such as the rotating speed of the compressor, the rotating speed of the fan and the like in the last 1 hour.

In the embodiment of the invention, the environmental temperature and humidity values stored in the refrigerator are unpredictable, and the system can query the environmental parameters every other unit time so as to match the model library of the corresponding environmental temperature and humidity. The method comprises the steps that test inclusion is carried out on each set parameter condition of the running state of the refrigerator in advance, the conditions contained in the model library are enough to contain the actual running state of the refrigerator, and for special conditions such as the load of after-sales personnel for replacing the model of the refrigerator by mistake or the state loss of the model library caused by negligence, the refrigerator can actively report the fault to a cloud end and carry out relevant information prompt on a display device and a mobile phone end of the refrigerator, and the cloud end can continuously carry out optimization updating of the electric quantity model library according to the actual conditions.

Specifically, the user behavior power consumption is the power consumption of the light module and the display, and the user behavior power consumption model records a plurality of refrigeration door opening time periods and corresponding user behavior power consumption in unit time, and records a plurality of display starting time periods and corresponding user behavior power consumption in unit time. When no user behavior exists, the display and the light module are not started at the moment, and the power consumption of the two devices in unit time is 0.

Specifically, in step S3, the obtained power consumption in unit time is accumulated with the power consumption obtained previously, so as to obtain the real-time power consumption of the refrigerator.

Specifically, the refrigerator power consumption monitoring method further comprises the following steps:

When a power consumption inquiry instruction sent by a refrigerator display is received, acquiring an inquiry time period written in the power consumption inquiry instruction;

acquiring corresponding target refrigeration power consumption, target user behavior power consumption and target conventional power consumption in unit time according to the query time period;

Accumulating the target refrigeration power consumption, the target user behavior power consumption and the target conventional power consumption to obtain target power consumption;

the user may input the power consumption inquiry command on the display, or remotely send the power consumption inquiry command through the client. For example, the user needs to inquire about the power consumption in a week, at this time, the user can input the start time and the end time to be inquired in the display, the display writes the two times into the power consumption inquiry command, and the controller obtains the two times as inquiry basis when receiving the power consumption inquiry command. After the controller calculates the power consumption in a unit time, the power consumption is stored, so that the subsequent calculation is convenient.

Specifically, the refrigerator power consumption monitoring method further comprises the following steps:

Comparing the current period power consumption in the current period with the historical period power consumption in the historical period every interval preset period to obtain an abnormal judgment result of the current period power consumption;

and when the abnormality judgment result is abnormal, sending out early warning prompt information.

By way of example, since the user habit makes the power consumption of the refrigerator in one operation period not greatly different, comparing the new period with the history period can determine whether the power consumption of the new period is abnormal, and the presence of the abnormality indicates that some devices may be faulty. When the controller detects that the power consumption of a certain day is abnormally large or abnormally small, the controller can evaluate related faults. The early warning prompt information can be sent to a user client through the controller, for example, the early warning prompt information is sent in a short message mode, so that a user is reminded of whether the refrigerator has faults or not.

Specifically, if the operation parameter includes a plurality of sub-parameters corresponding to power consumption devices in the refrigeration system, the obtaining, based on the operation parameter, refrigeration power consumption corresponding to a unit time in the refrigeration power consumption model includes:

When each sub-parameter can find out the corresponding refrigeration parameter index equal to the value thereof in the refrigeration power consumption model, acquiring the corresponding refrigeration power consumption according to the refrigeration parameter index;

when any subparameter does not find the corresponding refrigeration parameter index equal to the numerical value thereof in the refrigeration power consumption model, parameter correction in a preset range is carried out on the subparameter, and the refrigeration parameter index equal to the numerical value thereof is found in the refrigeration power consumption model according to the corrected subparameter and other subparameters, and the corresponding refrigeration power consumption is obtained.

For example, for various states of the refrigerator self setting parameters, such as temperature, humidity of each compartment, power of different frequencies of the compressor, each state is completely controlled by the refrigerator control system, and all states are contained in the model library. For the actual environment stored in the refrigerator, in the data matching process, there may be a situation that part of parameters cannot correspond to model indexes, and there is a partial deviation, for example, the environment parameters corresponding to the models are temperature 20 and humidity 30, at this time, the corresponding models cannot be queried for the power consumption per unit time when the rotation speed of the compressor is x1, the rotation speed of the fan can be queried, at this time, the situation that the model library cannot be matched already appears is indicated, the controller can match the parameters when the power of the compressor is x2 (the data in the index table with the nearest value of x 1) by adopting a nearby consistent principle, then revises the rotation speed x1 into x2 for re-indexing, namely, the follow-up matching is carried out by modifying the condition of the subparameters, meanwhile, the situation can be uploaded to the cloud at the same time, the cloud can judge whether the abnormal condition appearing in the cloud needs to be processed independently according to the actual situation, if the abnormal condition is true, the update of the model library can be fed back to the laboratory for follow-up measurement, and then the staff updates the model library corresponding to the parameter.

It should be noted that, because there are many parameters related to the refrigeration power consumption model, there may be some cases where some parameters are not recorded in the model library, so the above-mentioned parameter correction process is needed, but the parameters related to the user behavior power consumption model are fewer (the time length and the power consumption correspondence relationship), so basically one index table can be included, so there may not be a case where the parameters cannot be corresponded (in fact, only the power consumption in unit time corresponding to different user behavior related devices need to be recorded in the table), and therefore, correction of the parameter value may not be needed.

Further, the refrigerator is further in communication connection with the client through the cloud server or the router, when the refrigerator and the client are in communication through the router, the refrigerator and the client are relatively close to each other, and a user can check the running 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, and a user can perform data interaction with the refrigerator through an APP installed in the client, and meanwhile remote control of the refrigerator can be achieved.

The controller reports the power consumption condition of the refrigerator to the cloud server at intervals (for example, 2 h), the cloud server establishes a data file of each refrigerator, and provides power consumption using reports of the refrigerator in different modes such as daily, weekly, monthly, annual and the like for users.

Compared with the prior art, the method for monitoring the power consumption of the refrigerator disclosed by the embodiment of the invention has the advantages that a plurality of power consumption models are prestored in the refrigerator, in the actual operation of the refrigerator, the power consumption in a period of time is obtained by acquiring the operation state of the refrigerator in a period of time and then matching with the power consumption models prestored in the refrigerator, and finally the total power consumption is obtained by accumulating the power consumption in a historical period of time without complex calculation flow. Different power consumption devices in the refrigerator adopt different power consumption models, devices related to refrigeration adopt refrigeration power consumption models, devices related to user behaviors adopt user behavior power consumption models, and some conventional devices unrelated to refrigeration and user behaviors can directly use self fixed power consumption to accumulate because the power consumption of the conventional devices is unchanged, so that the counted power consumption of the refrigerator can accurately reflect the actual power consumption of the refrigerator. The refrigerator disclosed by the invention does not need to separately add a hardware electric quantity module to carry out electric quantity statistics of the refrigerator, and saves the space and the cost of the refrigerator.

While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
