During the control of the target cooling circuit, the compressor's frequency is adjusted according to the rate of temperature change within the compartment. The compressor operating at this adjusted frequency generates enough cooling to simultaneously meet the cooling needs of different compartments, thus reducing energy consumption caused by frequent compressor operation due to varying cooling demands from different compartments at different times.

[0025] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this specification. Attached Figure Description

[0026] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.

[0027] Figure 1 This is a system structure diagram of one embodiment of the refrigerator of this application;

[0028] Figure 2 This is a flowchart of one embodiment of the refrigerator control method of this application;

[0029] Figure 3 This is a flowchart of one embodiment of the refrigerator control method of this application;

[0030] Figure 4 This is a flowchart of one embodiment of the refrigerator control method of this application;

[0031] Figure 5 This is a flowchart of one embodiment of the refrigerator control method of this application;

[0032] Figure 6 This is a hardware structure diagram of one embodiment of the refrigerator control system of this application. Detailed Implementation

[0033] To better understand the technical solution of this application, the control method for the refrigerator, the refrigerator, and the storage medium of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features in the following embodiments and implementations can be combined with each other.

[0034] Combination Figure 1As shown, this application provides a refrigerator, which includes a compressor 11, a condenser 12, a dryer filter 13, a solenoid valve 14, a first capillary tube 15, a second capillary tube 16, an evaporator 17, and a fan 18. The solenoid valve 14 includes a first valve and a second valve.

[0035] After compressor 11 starts operating, it compresses the gaseous refrigerant, increasing its pressure and temperature. The compressed, high-pressure, high-temperature gaseous refrigerant enters condenser 12, where it exchanges heat with the outside air through heat sinks, cooling down to become liquid refrigerant. After being filtered by dryer filter 13, the liquid refrigerant enters the first capillary tube 15 through the first valve of solenoid valve 14 or the second capillary tube 16 through the second valve of solenoid valve 14. The liquid refrigerant, after its pressure is reduced by the first capillary tube 15 or the second capillary tube 16, becomes a low-pressure, low-temperature liquid refrigerant. This low-pressure, low-temperature liquid refrigerant flows into evaporator 17, where it absorbs heat from inside the refrigerator, generating cooling capacity to cool the refrigerator compartment. The cooling capacity is then transported from evaporator 17 to the refrigerator compartments by starting fan 18. The refrigerant flows through the first capillary tube 15 at a relatively high flow rate, so that the refrigerant entering the evaporator 17 through the first capillary tube 15 can generate a larger cooling capacity. The refrigerant flows through the second capillary tube 16 at a relatively low flow rate, so that the refrigerant entering the evaporator 17 through the second capillary tube 16 can generate a smaller cooling capacity.

[0036] The current temperature of the refrigerator's compartments is detected to determine the refrigerator's cooling needs. Based on the current temperature, one of the refrigerator's multiple cooling circuits is selected as the target cooling circuit. This ensures that the cooling capacity generated by the refrigerator through the target cooling circuit precisely meets the current cooling needs, reducing energy waste caused by excessive cooling when the cooling demand is low.

[0037] Combination Figure 2 As shown, this application also provides a refrigerator control method including steps 201 to 203:

[0038] Step 201: Detect the current temperature of the refrigerator compartment.

[0039] Step 202: Based on the current temperature of the refrigerator compartment, determine one of the multiple refrigeration circuits of the refrigerator as the target refrigeration circuit.

[0040] Step 203: During the cooling process of the target refrigeration circuit of the refrigerator, adjust the current frequency of the compressor according to the temperature change rate of the compartment.

[0041] Detect the current temperature of the compartments of the refrigerator to determine the refrigeration demand of the refrigerator. According to the current temperature of the compartments of the refrigerator, determine one of the multiple refrigeration circuits of the refrigerator as the target refrigeration circuit. Ensure that the refrigeration capacity generated by the refrigerator through the target refrigeration circuit can just meet the current refrigeration demand of the refrigerator. And during the process of controlling the target refrigeration circuit of the refrigerator to refrigerate, adjust the current frequency of the compressor according to the temperature change rate of the compartment. The refrigeration capacity generated when the compressor operates at the adjusted frequency can meet the refrigeration demands of different compartments of the refrigerator at the same time, thereby reducing the energy consumption caused by the frequent startup of the compressor due to the refrigeration demands of different compartments at different times.

[0042] The refrigerator provided by the present application includes compartments. Optionally, the compartments include a freezer and a refrigerator compartment.

[0043] Optionally, before adjusting the current frequency of the compressor in step 203, the control method of the refrigerator further includes:

[0044] Obtain the current ambient temperature and the current working gear of the freezer of the refrigerator, and determine the current frequency of the compressor according to the current ambient temperature and the current working gear of the freezer of the refrigerator.

[0045] Furthermore, according to the mapping relationship between the ambient temperature and the working gear of the freezer of the refrigerator and the frequency of the compressor, determine the frequency of the compressor corresponding to the current ambient temperature and the current working gear of the freezer of the refrigerator as the current frequency of the compressor.

[0046] Exemplarily, the mapping relationship between the ambient temperature and the working gear of the freezer of the refrigerator and the frequency of the compressor is as follows:

[0047]

[0048] Among them, the data in the first column is the current working gear of the freezer, and the data in the first row is the ambient temperature. A1 < B1 < C1, A2 < B2 < C2. When the current ambient temperature is A1 degrees Celsius and the current working gear of the freezer is A2 degrees Celsius, determine the current frequency of the compressor as X1. When the current ambient temperature is B1 degrees Celsius and the current working gear of the freezer is B2 degrees Celsius, determine the current frequency of the compressor as Y2, X1 < Y2. The working gear of the freezer is positively correlated with the refrigeration capacity required by the freezer, and the ambient temperature is also positively correlated with the refrigeration capacity required by the freezer. That is, at a high ambient temperature or when the working gear of the freezer is higher, the compressor operates at a higher frequency; while at a low ambient temperature or when the demand of the freezer is lower, the compressor operates at a lower frequency. It should be noted that the current frequency of the compressor determined through the above mapping relationship is the operating frequency of the compressor in the initial state. The refrigeration capacity generated by making the compressor operate at this current frequency in the initial state can quickly meet the refrigeration demand of the freezer.

[0049] The following describes, with reference to specific embodiments, how to reduce the energy consumption of a refrigerator by determining the target refrigeration circuit.

[0050] Combination Figure 3 As shown, the refrigerator control method includes steps 301 to 303:

[0051] Step 301: Detect the current temperature of the freezer compartment.

[0052] Step 302, determine if Tf ≥ Tfon? Where Tf represents the current temperature of the freezer compartment, and Tfon represents the start-up temperature of the freezer compartment, which is the temperature required for the freezer compartment to start its cooling function.

[0053] If the current temperature of the freezer compartment is greater than or equal to the start-up temperature of the freezer compartment, then proceed to step 303.

[0054] Step 303, determine if Tr ≥ Tron? Where Tr represents the current temperature of the refrigerator compartment, and Tron represents the start-up temperature of the refrigerator compartment, which is the temperature required for the refrigerator compartment to start its cooling function.

[0055] Detect the current temperature of the refrigerator compartment. If the current temperature of the refrigerator compartment is greater than or equal to the start-up temperature of the refrigerator compartment, proceed to step 304. If the current temperature of the refrigerator compartment is less than the start-up temperature of the refrigerator compartment, proceed to step 305.

[0056] Step 304: The first refrigeration circuit is determined as the target refrigeration circuit of the refrigerator.

[0057] Step 305: The second refrigeration circuit is determined as the target refrigeration circuit of the refrigerator.

[0058] Step 306: Adjust the current frequency of the compressor according to the rate of temperature change in the compartment.

[0059] If the current temperature of the freezer compartment is greater than or equal to the freezer compartment's start-up temperature, that is, the freezer compartment has reached the temperature at which the cooling function is activated, it indicates that the freezer compartment of the refrigerator has a cooling demand, and the current temperature of the refrigerator compartment is then detected.

[0060] If the current temperature of the refrigerator compartment is greater than or equal to its start-up temperature, meaning the refrigerator compartment has reached the temperature required to activate its cooling function, it indicates that the refrigerator compartment also has a cooling demand. In this case, since both the freezer and refrigerator compartments have cooling needs simultaneously, the refrigerator's cooling demand is relatively high, and the first refrigeration circuit is determined as the target refrigeration circuit. The first valve is opened, and the second valve is closed, allowing the refrigerant to flow through the first valve at a higher flow rate through the first capillary tube. This ensures that the refrigerant entering the evaporator through the first capillary tube can generate a greater cooling capacity to simultaneously meet the cooling needs of both the freezer and refrigerator compartments.

[0061] If the current temperature of the refrigerator compartment is lower than its start-up temperature, meaning the refrigerator compartment has not reached the temperature required to activate the cooling function, it indicates that the refrigerator compartment does not require cooling. In this case, only the freezer compartment requires cooling, so the refrigerator's cooling demand is relatively small. Therefore, the second refrigeration circuit is determined as the target refrigeration circuit. The second valve is opened, and the first valve is closed, allowing the refrigerant to flow through the second valve at a smaller flow rate through the second capillary tube. This ensures that the refrigerant entering the evaporator through the second capillary tube produces a smaller amount of cooling to meet the freezer compartment's cooling demand.

[0062] The current temperature of the refrigerator's compartments is detected to determine the refrigerator's cooling needs. Based on the current temperature, one of the refrigerator's multiple cooling circuits is selected as the target cooling circuit. This ensures that the cooling output of the refrigerator through the target cooling circuit precisely meets the current cooling needs, thereby reducing the refrigerator's energy consumption.

[0063] The following describes, with reference to a specific embodiment, how to adjust the current frequency of the compressor during the cooling process of the first refrigeration circuit in a refrigerator.

[0064] Combination Figure 4 As shown, the refrigerator control method includes steps 401 to 405:

[0065] Step 401: Detect the current temperature of the freezer compartment.

[0066] Step 402: If the current temperature of the freezer compartment is greater than or equal to the start-up temperature of the freezer compartment, detect the current temperature of the refrigerator compartment.

[0067] Step 403: If the current temperature of the refrigerator compartment is greater than or equal to the start-up temperature of the refrigerator compartment, the first refrigeration circuit is determined as the target refrigeration circuit of the refrigerator.

[0068] Step 404: Obtain the first remaining time for shutting down the freezer compartment and the second remaining time for shutting down the refrigerator compartment.

[0069] The first remaining time for shutting down the freezer compartment is determined based on the rate of temperature change in the freezer compartment and its shutdown temperature. The second remaining time for shutting down the refrigerator compartment is determined based on the rate of temperature change in the refrigerator compartment and its shutdown temperature. The shutdown temperature of the freezer compartment is the temperature required for the freezer compartment to shut down and then start its cooling function, and the shutdown temperature of the refrigerator compartment is the temperature required for the refrigerator compartment to shut down and then start its cooling function.

[0070] Optionally, obtaining the rate of temperature change in the compartment includes:

[0071] Obtain the historical temperature of the compartment before a preset time period, and determine the temperature change rate of the compartment based on the historical temperature, the current temperature, and the preset time period.

[0072] For example, if the preset duration is 1 minute, the current temperature of the freezer compartment is -25 degrees Celsius, and the historical temperature of the freezer compartment 1 minute ago was -20 degrees Celsius, then the rate of temperature change of the freezer compartment is: Degrees Celsius per minute. If the freezer's shut-off temperature is -35 degrees Celsius, then the first remaining time is... minute.

[0073] Step 405: If the second remaining duration is greater than the first remaining duration, increase the current frequency of the compressor.

[0074] If the second remaining time is greater than the first remaining time, the compressor's current frequency is increased. If the second remaining time is less than or equal to the first remaining time, the compressor runs at the current frequency until the current temperature of the freezer compartment reaches the freezer compartment's shutdown temperature, at which point the compressor shuts off.

[0075] Assuming the first refrigeration circuit is designated as the target refrigeration circuit for the refrigerator, both the freezer and refrigerator compartments are refrigerated. The system then checks if the second remaining time after the freezer is turned off is greater than the first remaining time after the refrigerator is turned off. If the second remaining time is greater than the first remaining time, it indicates that the refrigerator compartment's refrigeration function was still running when the freezer turned off after the first remaining time. When the freezer is turned off, the compressor shuts off. When the refrigerator is running, the damper between the freezer and refrigerator compartments opens, allowing cooling capacity from the freezer to enter the refrigerator compartment, thus reducing the cooling capacity of the freezer and causing its temperature to rise. When the freezer's current temperature rises to its operating temperature, the compressor restarts to cool the freezer, resulting in frequent compressor starts and stops.

[0076] In the refrigerator control method of this application, if it is determined that the second remaining time is greater than the first remaining time, the current frequency of the compressor is increased to improve the refrigerator's cooling efficiency, and both the first and second remaining times are shortened. Furthermore, the increased cooling capacity produced by the compressor after the frequency increase makes it easier to meet the cooling needs of the refrigerator compartment, as the cooling capacity required by the refrigerator compartment is much smaller than that required by the freezer compartment. Therefore, after the current frequency of the compressor is increased, there is a possibility that the shortened second remaining time may be less than the shortened first remaining time. When the refrigerator reaches the shortened first remaining time, the freezer compartment shuts off its cooling function. Since the shortened second remaining time is less than the shortened first remaining time, the refrigerator compartment also shuts off its cooling function when the refrigerator reaches the shortened first remaining time, thus closing the damper. Cooling capacity in the freezer compartment will not enter the refrigerator compartment through the damper, thereby reducing the frequency of compressor operation. This reduces energy consumption caused by the frequent compressor operation due to different compartments generating cooling demand at different times.

[0077] During the cooling process of the first refrigeration circuit of the refrigerator, it is determined whether the second remaining time after the refrigerator compartment is turned off is greater than the first remaining time after the freezer compartment is turned off. If the second remaining time is greater than the first remaining time, the current frequency of the compressor is increased. This ensures that the cooling capacity generated by the compressor running at the increased frequency can simultaneously meet the cooling needs of different compartments in the refrigerator, thereby reducing energy consumption caused by the compressor frequently starting due to different compartments generating cooling needs at different times.

[0078] The following describes, with reference to a specific embodiment, how to adjust the current frequency of the compressor during the cooling process of the second refrigeration circuit in a refrigerator.

[0079] Combination Figure 5 As shown, the refrigerator control method includes steps 501 to 505:

[0080] Step 501: Detect the current temperature of the freezer compartment.

[0081] Step 502: If the current temperature of the freezer compartment is greater than or equal to the start-up temperature of the freezer compartment, detect the current temperature of the refrigerator compartment.

[0082] Step 503: If the current temperature of the refrigerator compartment is lower than the start-up temperature of the refrigerator compartment, the second refrigeration circuit is determined as the target refrigeration circuit of the refrigerator.

[0083] Step 504: Obtain the first remaining time for the freezer compartment to be turned off and the third remaining time for the refrigerator compartment to be turned on.

[0084] The remaining third operating time of the refrigerator compartment is determined based on the rate of temperature change in the refrigerator compartment and the start-up temperature of the refrigerator compartment. The start-up temperature of the refrigerator compartment is the temperature required for the refrigerator compartment to activate its cooling function.

[0085] Step 505: If the third remaining duration is greater than the first remaining duration, reduce the current frequency of the compressor.

[0086] If the third remaining time is greater than the first remaining time, the compressor's current frequency is reduced. If the third remaining time is less than or equal to the first remaining time, the compressor runs at the current frequency until the current temperature of the freezer compartment reaches the freezer compartment's shutdown temperature, at which point the compressor shuts off.

[0087] If the second refrigeration circuit is designated as the target refrigeration circuit for the refrigerator, only the freezer compartment will have its refrigeration function activated. The system then checks if the third remaining time after the refrigerator compartment is turned on is greater than the first remaining time after the freezer compartment is turned off. If the third remaining time is greater than the first remaining time, it means that the refrigerator compartment's refrigeration function was not activated when the freezer compartment turned off during the first remaining time. When the freezer compartment's refrigeration function is off, the compressor turns off. When the refrigerator reaches the third remaining time, the refrigerator compartment's refrigeration function is activated, the damper opens, and the cooling capacity from the freezer compartment enters the refrigerator compartment through the damper, thus reducing the cooling capacity of the freezer compartment and causing its temperature to rise. When the current temperature of the freezer compartment rises to the freezer compartment's activation temperature, the compressor restarts to cool the freezer compartment, resulting in frequent compressor starts and stops.

[0088] In the refrigerator control method of this application, if it is determined that the third remaining time is greater than the first remaining time, the current frequency of the compressor is reduced, thereby decreasing the refrigerator's cooling efficiency and extending the first remaining time. When the third remaining time is less than or equal to the extended first remaining time, the refrigerator operates until the third remaining time has elapsed. The refrigerator compartment activates its cooling function, while the freezer compartment remains refrigerated. The refrigerator compartment activates its cooling function, causing the damper to open. Cooling capacity from the freezer compartment enters the refrigerator compartment through the damper, allowing the compressor to simultaneously meet the cooling needs of different compartments during operation, thus reducing the frequency of compressor activation.

[0089] During the cooling process of the refrigerator's second refrigeration circuit, it is determined whether the third remaining time after the refrigerator compartment is turned on is greater than the first remaining time after the freezer compartment is turned off. If the third remaining time is greater than the first remaining time, the current frequency of the compressor is reduced. This ensures that the cooling capacity generated by the compressor running at the reduced frequency can simultaneously meet the cooling needs of different compartments in the refrigerator, thereby reducing energy consumption caused by the compressor frequently starting due to different compartments generating cooling needs at different times.

[0090] Optionally, adjusting the current frequency of the compressor includes:

[0091] Adjust the compressor's current frequency according to the preset setting.

[0092] The preset setting indicates the preset minimum frequency unit of the compressor. Adjusting the compressor's current frequency according to the preset minimum frequency unit improves the accuracy of the adjustment process.

[0093] The refrigerator provided in this application also includes a control system, such as Figure 6 As shown, the control system includes a processor 601, an internal bus 602, a network interface 603, memory 604, and non-volatile memory 605, and may also include other hardware required for business operations. The processor 601 reads the corresponding computer program from the non-volatile memory 605 into the memory 604 and then runs it to implement the refrigerator detection method described above. Of course, in addition to software implementation, this specification does not exclude other implementation methods, such as logic devices or a combination of hardware and software, etc. That is to say, the execution subject of the following processing flow is not limited to individual logic units, but can also be hardware or logic devices.
