Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and more specifically, to a refrigerator control method, device, storage medium, and refrigerator. Background Technology

[0002] In related technologies, when a refrigerator is started for the first time, or restarted after a power outage, a high cooling capacity and a large air volume are usually used to quickly lower the temperature inside the refrigerator compartment. However, since the temperature of the heat exchanger itself is the same as the temperature inside the refrigerator compartment at the beginning, although a large air volume is provided, the heat exchanger itself does not drop in temperature, resulting in ineffective heat exchange. At the same time, due to the large air volume and the large amount of ineffective heat exchange, the cooling speed inside the refrigerator compartment is still relatively slow. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the related art.

[0004] Therefore, the first aspect of the present invention is to provide a method for controlling a refrigerator.

[0005] A second aspect of the present invention is to provide a control device for a refrigerator.

[0006] A third aspect of the present invention is to provide a control device for a refrigerator.

[0007] A fourth aspect of the present invention is to provide a readable storage medium.

[0008] The fifth aspect of the present invention is to provide a refrigerator.

[0009] In view of this, according to one aspect of the present invention, a control method for a refrigerator is proposed, the refrigerator including a heat exchanger and a plurality of compartments, the control method comprising: when the heat exchanger is operating, acquiring the current cooling temperature of the heat exchanger and the compartment temperature of at least one of the plurality of compartments; and adjusting the airflow and / or cooling capacity entering at least one of the plurality of compartments according to the current cooling temperature and the compartment temperature.

[0010] It should be noted that the execution subject of the refrigerator control method proposed in this invention can be the refrigerator control device. In order to more clearly explain the refrigerator control method proposed in this invention, the following technical solution uses the refrigerator control device as the execution subject of the refrigerator control method for illustrative purposes.

[0011] In this technical solution, the aforementioned heat exchanger is used to indicate the refrigeration components of the refrigerator, such as the evaporator and condenser.

[0012] Specifically, when the control device determines that the heat exchanger is in operation, it acquires in real time the surface temperature of the heat exchanger (i.e., the current cooling temperature) and the compartment temperature of at least one of the multiple compartments of the refrigerator.

[0013] Specifically, a temperature sensor is installed in the heat exchanger and in any of the multiple compartments, and the control device can obtain the current cooling temperature and the temperature of the compartment through the temperature sensor.

[0014] Furthermore, the control device adjusts the airflow and / or cooling capacity entering at least one of the multiple compartments of the refrigerator based on the real-time acquired current cooling temperature and compartment temperature. Specifically, the temperature difference between the refrigerator's compartment temperature and the refrigerator's heat exchanger can be determined based on the current cooling temperature and compartment temperature. Based on this temperature difference, the airflow and / or cooling capacity flowing into the compartment that matches the temperature difference can be determined. Then, the airflow and / or cooling capacity flowing into at least one of the multiple compartments can be adjusted based on the airflow and / or cooling capacity that matches the temperature difference.

[0015] In this technical solution, the control device can adjust the airflow and / or air volume flowing into at least one compartment based on the current cooling temperature and the compartment temperature of at least one compartment, which are obtained in real time when the refrigerator's heat exchanger is in operation.

[0016] In the technical solution of this invention, based on the current cooling temperature and the compartment temperature, the temperature difference between the temperature inside at least one compartment and the cooling temperature of the heat exchanger can be determined. Based on this temperature difference, the required airflow and / or cooling capacity for that compartment can be determined, ensuring that the airflow and / or cooling capacity flowing into at least one compartment matches the temperature difference. This avoids ineffective heat exchange due to a mismatch between the airflow and / or cooling capacity and the cooling temperature of the heat exchanger, improving the heat exchange efficiency of the heat exchanger and increasing the cooling rate of at least one compartment in the refrigerator.

[0017] Furthermore, the refrigerator control method proposed according to the above-described technical solution of the present invention may also have the following additional technical features:

[0018] In the above technical solution, before obtaining the current cooling temperature of the heat exchanger and the room temperature of at least one of the multiple rooms, the control method further includes: determining the adjustment sequence of the air volume and / or cooling capacity of the multiple rooms according to the adjustment priority level of the multiple rooms.

[0019] In this technical solution, before the control device obtains the current cooling temperature of the heat exchanger surface and the compartment temperature of at least one of the multiple compartments of the refrigerator through the temperature sensor, the control device also needs to determine the specific order of adjusting the air volume and / or cooling capacity of the multiple compartments of the refrigerator according to the preset adjustment priority level.

[0020] Specifically, since a refrigerator may include multiple compartments, and the heat exchanger cannot simultaneously adjust the temperature of the multiple compartments to the target temperature set by the user, the control device needs to determine the specific adjustment sequence of the multiple compartments according to the pre-set adjustment priority level.

[0021] Specifically, since the refrigerated compartment is opened and closed more frequently, its adjustment priority can be set to the highest level; or, since users pay more attention to the food stored in the frozen compartment, its adjustment priority can be set to the highest level. In essence, the adjustment priority level is set according to the user's requirements, and this invention does not impose any limitations on it.

[0022] In this technical solution, before obtaining the current cooling temperature and the temperature of at least one compartment, the control device needs to determine the specific adjustment sequence of the multiple compartments of the refrigerator according to a pre-set adjustment priority level. This allows subsequent steps to quickly adjust the temperature of the compartment with the higher priority level to the user-set target temperature according to this adjustment sequence, improving user satisfaction.

[0023] In the above technical solution, the multiple compartments include at least one refrigerator compartment and at least one freezer compartment, and the adjustment priority of at least one refrigerator compartment is higher than that of at least one freezer compartment.

[0024] In this technical solution, the refrigerator includes at least one refrigerator compartment and at least one freezer compartment. Specifically, in the priority adjustment, the priority level of the at least one refrigerator compartment is higher than that of the at least one freezer compartment.

[0025] Specifically, since the refrigerated compartments open and close more frequently, in order to ensure the preservation capacity of the refrigerated compartments, the priority level of the refrigerated compartments needs to be set above that of the freezer compartments in the adjustment priority level.

[0026] In this technical solution, the refrigerator has multiple compartments, including at least one refrigerator compartment and at least one freezer compartment. During temperature adjustment, the priority of at least one refrigerator compartment is higher than that of at least one freezer compartment. This avoids the situation where the refrigerator compartment's preservation ability is weak due to frequent opening and closing of at least one refrigerator compartment.

[0027] In the above technical solution, the control method further includes: adjusting the air volume and / or cooling capacity entering the at least one room when the rate of change of the difference between the room temperature of at least one room and the current cooling temperature exceeds a predetermined threshold; and / or adjusting the air volume and / or cooling capacity entering the at least one room when the room temperature of at least one room changes and the rate of change exceeds a predetermined threshold.

[0028] In this technical solution, the control device adjusts the airflow and / or cooling capacity of at least one of the multiple compartments flowing into the refrigerator based on the current cooling temperature and the compartment temperature. This can be achieved by the control device determining the temperature difference between the compartment temperature of the at least one compartment and the current cooling temperature, and then comparing the rate of change of the temperature difference with a preset threshold.

[0029] Specifically, when the control device determines that the rate of change of the temperature difference between the above-mentioned room temperature and the above-mentioned current cooling temperature exceeds a preset threshold, the control device determines that it is necessary to adjust the air volume and / or cooling capacity flowing into at least one room.

[0030] Specifically, if the rate of change of the temperature difference between the above-mentioned room temperature and the above-mentioned current cooling temperature exceeds a preset threshold, it indicates that the temperature difference between the room temperature and the cooling temperature in at least one room being adjusted has changed. At this time, in order to ensure that the air volume and / or cooling capacity flowing into the room matches the above-mentioned temperature difference and to avoid ineffective heat exchange, the control device needs to adjust the air volume and / or cooling capacity flowing into the room.

[0031] Specifically, the control device may adjust the airflow and / or cooling capacity of at least one of the multiple compartments flowing into the refrigerator based on the current cooling temperature and the compartment temperature. Alternatively, the control device may monitor the compartment temperature of at least one of the multiple compartments in real time, and when the compartment temperature changes and the rate of change exceeds a predetermined threshold, determine that the airflow and / or cooling capacity flowing into at least one compartment needs to be adjusted.

[0032] Specifically, if the rate of change of temperature in at least one monitored room exceeds a predetermined threshold, it indicates that the temperature in at least one room is too low or too high. In this case, in order to ensure that the temperature in at least one room is within the range set by the user, the control device needs to adjust the airflow and / or cooling capacity flowing into the room.

[0033] In this technical solution, the control device can determine whether it is necessary to adjust the airflow and / or cooling capacity flowing into the at least one compartment based on changes in the compartment temperature or changes in the temperature difference between the compartment temperature and the current cooling temperature. Thus, during the adjustment of the temperature of multiple compartments of the refrigerator, the airflow and / or cooling capacity flowing into that compartment are always matched with the temperature difference, ensuring that the temperature in the at least one compartment remains within the user-set range, thereby guaranteeing the preservation capability of at least one of the refrigerator's multiple compartments.

[0034] In the above technical solution, when the rate of change of the difference between the temperature of at least one room and the current cooling temperature is greater than or equal to a first change threshold, or when the increase in the temperature of at least one room is greater than or equal to a first temperature threshold, the air volume and / or cooling capacity of at least one room are increased.

[0035] In this technical solution, the control device first determines the temperature difference between the room temperature of the at least one compartment and the current cooling temperature, and compares the rate of change of the temperature difference with the magnitude of a first change threshold, or determines the temperature increase of the room temperature of the at least one compartment and compares the temperature increase with the magnitude of a first temperature threshold.

[0036] Specifically, when the control device determines that the rate of change of the temperature difference between the above-mentioned room temperature and the above-mentioned current cooling temperature is greater than or equal to the above-mentioned first change threshold, the control device determines that it is necessary to increase the air volume and / or cooling capacity flowing into at least one room.

[0037] Specifically, if the rate of change of the temperature difference between the above-mentioned room temperature and the above-mentioned current cooling temperature is greater than or equal to the above-mentioned first change threshold, it indicates that the temperature difference between the at least one room being adjusted and the cooling temperature has become smaller. At this time, increasing the airflow into the room will not result in ineffective heat exchange. In order to accelerate the cooling rate of the at least one room, the control device needs to increase the airflow and / or cooling capacity into the at least one room.

[0038] Specifically, when the control device determines that the temperature increase of the aforementioned compartment is greater than or equal to the aforementioned first temperature threshold, the control device determines that it is necessary to increase the airflow and / or cooling capacity flowing into at least one compartment.

[0039] Specifically, if the temperature increase of at least one monitored compartment is greater than or equal to the first temperature threshold, it may indicate that during the process of the control device adjusting the temperature of a compartment with a high priority, the temperature increase of at least one compartment with a low priority exceeds the threshold, that is, the temperature of at least one compartment with a low priority is too high. In this case, the control device needs to increase the airflow and / or cooling capacity into the compartment in order to quickly adjust the temperature in the compartment to the normal operating temperature.

[0040] Specifically, if the temperature increase of at least one of the monitored compartments is greater than or equal to the first temperature threshold, it may also indicate that during the stable operation of the refrigerator, the temperature in at least one compartment suddenly rises due to the user storing or taking out food. In this case, the control device needs to increase the airflow and / or cooling capacity into the compartment to quickly adjust the temperature in the compartment to the normal operating temperature.

[0041] In this technical solution, the control device can determine whether it is necessary to increase the airflow and / or cooling capacity flowing into the at least one compartment based on the increase in the temperature of the compartment in the refrigerator or based on the rate of change of the temperature difference between the compartment temperature and the current cooling temperature. This avoids ineffective heat exchange and accelerates the cooling rate of at least one compartment during the temperature adjustment of multiple compartments of the refrigerator; it also ensures the preservation capacity of compartments with lower temperature priority during temperature adjustment of compartments with higher priority; and it can quickly restore the temperature of compartments that have suddenly risen to normal levels during stable refrigerator operation.

[0042] In the above technical solutions, the methods of increasing the air volume and / or cooling capacity of at least one room include at least one of the following or a combination thereof: directly increasing the air volume and / or cooling capacity of at least one room; closing or reducing the air volume and / or cooling capacity of one or more rooms other than at least one room.

[0043] In this technical solution, the control device increases the airflow and / or cooling capacity flowing into the at least one compartment in one or more of the following ways: First, the control device directly increases the airflow and / or cooling capacity flowing into the at least one compartment; Second, the control device closes or reduces the airflow and / or cooling capacity flowing into multiple or one compartment of the refrigerator, excluding the at least one compartment.

[0044] Specifically, for refrigerators that can directly adjust airflow and / or cooling capacity, the control device can directly control the air supply equipment and the aforementioned heat exchanger to increase the airflow and / or cooling capacity flowing into the at least one compartment. For some refrigerators, since the airflow and / or cooling capacity flowing into the refrigerator compartment is fixed, the control device needs to increase the airflow and / or cooling capacity flowing into the at least one compartment by closing or reducing the airflow and / or cooling capacity flowing into multiple or one compartment in multiple compartments of the refrigerator, excluding the at least one compartment.

[0045] For example, for a refrigerator that can directly adjust the air volume and / or cooling capacity, the control device can also increase the air volume and / or cooling capacity flowing into the at least one compartment by directly increasing the air volume and / or cooling capacity flowing into the at least one compartment and closing or reducing the air volume and / or cooling capacity flowing into multiple or one compartment of the refrigerator in addition to the at least one compartment.

[0046] In the above technical solution, when the air volume and / or cooling capacity of one or more rooms in other rooms besides at least one room are closed or reduced, the temperature rise rate of one or more rooms in other rooms is detected, and / or the rate of change of the temperature difference between the room temperature of one or more rooms in other rooms and the current cooling temperature is detected.

[0047] In this technical solution, when the control device increases the airflow and / or cooling capacity flowing into the at least one compartment, and it is necessary to close or reduce the airflow and / or cooling capacity flowing into multiple or one compartment of the refrigerator in addition to the at least one compartment, the control device also needs to detect the compartment temperature of multiple compartments or one compartment of the refrigerator in addition to the at least one compartment.

[0048] Furthermore, the control device calculates the temperature rise rate of multiple rooms or one room based on the detected room temperature, and / or calculates the rate of change of the temperature difference between the current cooling temperature of the heat exchanger and the room temperature of multiple rooms or one room, that is, calculates the temperature rise rate of the room in the multiple rooms where the air volume and / or cooling capacity are closed or reduced, and / or calculates the rate of change of the temperature difference between the current cooling temperature of the heat exchanger and the room in the multiple rooms where the air volume and / or cooling capacity are closed or reduced.

[0049] Specifically, based on the aforementioned temperature rise rate and / or the aforementioned temperature difference change rate, the specific temperature changes in the compartments of the refrigerator with the airflow and / or cooling capacity reduced or closed can be determined, so that in subsequent steps, when the temperature in a compartment is too high, the airflow and / or cooling capacity flowing into that compartment can be adjusted in a timely manner.

[0050] In this technical solution, when the control device closes or reduces the airflow and / or cooling capacity flowing into multiple or one compartment of the refrigerator (excluding at least one of the compartments mentioned above), and then increases the airflow and / or cooling capacity flowing into the at least one compartment, the control device needs to detect and calculate the temperature rise rate in the compartments where the airflow and / or cooling capacity is closed or reduced, and / or calculate the rate of change of the temperature difference between the current cooling temperature of the heat exchanger and the temperature difference in the compartments where the airflow and / or cooling capacity is closed or reduced. This is so that in subsequent steps, when the temperature in a compartment is too high, the airflow and / or cooling capacity flowing into that compartment can be adjusted in a timely manner.

[0051] In the above technical solution, if the temperature rise rate of one or more other rooms is detected to be greater than or equal to a predetermined rise rate threshold, and / or the rate of change of the difference is greater than or equal to a rate of change threshold, the air volume and / or cooling capacity of the corresponding room are adjusted.

[0052] In this technical solution, when the temperature rise rate in the multiple compartments where the air volume and / or cooling capacity is closed or reduced is greater than or equal to a predetermined rise threshold, and / or when the rate of change of the temperature difference between the current cooling temperature of the heat exchanger and the multiple compartments where the air volume and / or cooling capacity is closed or reduced is greater than or equal to a rate of change threshold, the control device needs to adjust the air volume and / or cooling capacity flowing into the corresponding compartments in the multiple compartments where the air volume and / or cooling capacity is closed or reduced.

[0053] Specifically, if the temperature rise rate is greater than or equal to the predetermined rise rate threshold, it indicates that the temperature in the compartment where the air volume and / or cooling capacity is closed or reduced is too high. In this case, the control device needs to adjust the air volume and / or cooling capacity flowing into the corresponding compartment to reduce the temperature in the corresponding compartment in order to ensure the preservation capacity of the corresponding compartment.

[0054] Specifically, if the rate of change of the temperature difference is greater than or equal to the rate of change threshold, it indicates that in the multiple rooms where the air volume and / or cooling volume are closed or reduced, the air volume and / or cooling volume flowing into the corresponding room does not match the temperature difference. In this case, in order to avoid ineffective heat exchange, the control device needs to adjust the air volume and / or cooling volume flowing into the corresponding room.

[0055] In this technical solution, when the control device detects and calculates that the temperature rise rate is greater than or equal to the predetermined rise rate threshold, and / or the temperature difference change rate is greater than or equal to the change rate threshold, the control device needs to adjust the airflow and / or cooling capacity flowing into the corresponding compartment. This lowers the temperature in the corresponding compartment, ensuring its preservation capacity; and / or ensures that the airflow and / or cooling capacity flowing into the corresponding compartment matches the temperature difference, thus preventing ineffective heat exchange within the refrigerator compartment.

[0056] In the above technical solution, the method of adjusting the air volume and / or cooling capacity entering each compartment includes at least one of the following or a combination thereof: adjusting the opening degree of the damper of each compartment; adjusting the power of the refrigerator's heat exchanger; adjusting the speed of the refrigerator's fan; controlling the opening and closing of at least one of the multiple fans when the refrigerator includes multiple fans; and controlling the speed of at least one of the multiple fans when the refrigerator includes multiple fans.

[0057] In this technical solution, the control device can adjust the airflow and / or cooling capacity of any one of the multiple compartments flowing into the refrigerator through one or more of the following methods in combination: First, adjusting the opening degree of the damper corresponding to each of the multiple compartments; Second, adjusting the operating power of the heat exchanger; Third, adjusting the speed of the refrigerator fan; Fifth, when there are multiple fans in the refrigerator, controlling at least one of the multiple fans to turn on or off; Sixth, when there are multiple fans in the refrigerator, adjusting the speed of at least one of the multiple fans.

[0058] Furthermore, refrigerators are generally equipped with regulating valves, which can be used to regulate the airflow to the heat exchanger. The control device can also adjust the cooling capacity of any one of the multiple compartments of the refrigerator by adjusting the opening of the regulating valve.

[0059] Furthermore, the control device can also regulate the amount of cold air flowing into any of the multiple compartments of the refrigerator by adjusting the speed of the refrigerator compressor motor.

[0060] In the above technical solution, when the refrigerator includes multiple fans, at least one of the multiple fans provides airflow to at least one of the multiple compartments.

[0061] In this technical solution, when it is determined that the refrigerator is equipped with multiple fans for adjusting air volume, at least one of the multiple fans can provide air volume to at least one of the multiple compartments.

[0062] Specifically, each fan corresponds one-to-one with one of the aforementioned rooms, meaning that one fan provides airflow to one corresponding room.

[0063] Furthermore, the aforementioned multiple fans and multiple compartments may not correspond one-to-one, but rather to the air ducts connected to the air dampers of the multiple compartments. That is, the multiple compartments provide airflow to the air ducts, and the air ducts provide airflow to the multiple compartments through the air dampers.

[0064] According to a second aspect of the present invention, a control device for a refrigerator is provided, the control device comprising: an acquisition module for acquiring the current cooling temperature of the heat exchanger and the compartment temperature of at least one of the plurality of compartments when the heat exchanger is operating; and a processing module for adjusting the airflow and / or cooling capacity entering at least one of the plurality of compartments according to the current cooling temperature and the compartment temperature.

[0065] In this technical solution, the aforementioned heat exchanger is used to indicate the refrigeration components of the refrigerator, such as the evaporator and condenser.

[0066] Specifically, when it is determined that the heat exchanger is in operation, the acquisition module acquires in real time the surface temperature of the heat exchanger (i.e., the current cooling temperature) and the compartment temperature of at least one of the multiple compartments of the refrigerator.

[0067] Specifically, a temperature sensor is installed in the heat exchanger and in any of the multiple compartments, and the acquisition module can obtain the current cooling temperature and the temperature of the compartment through the temperature sensor.

[0068] Furthermore, the processing module adjusts the airflow and / or cooling capacity entering at least one of the multiple compartments of the refrigerator based on the real-time acquired current cooling temperature and compartment temperature. Specifically, the processing module can determine the temperature difference between the refrigerator's compartment temperature and the refrigerator's heat exchanger's cooling temperature based on the current cooling temperature and compartment temperature. The processing module can determine the airflow and / or cooling capacity flowing into the compartment that matches the temperature difference based on this temperature difference, and then adjust the airflow and / or cooling capacity flowing into at least one of the multiple compartments based on the airflow and / or cooling capacity matching the temperature difference.

[0069] In this technical solution, the acquisition module can acquire the current cooling temperature and the temperature of at least one compartment in real time when the refrigerator's heat exchanger is in operation. The processing module can adjust the airflow and / or cooling capacity flowing into the at least one compartment based on the current cooling temperature and the compartment temperature. In this invention, the temperature difference between the temperature in at least one compartment and the cooling temperature of the heat exchanger can be determined based on the current cooling temperature and the compartment temperature. Based on this temperature difference, the required airflow and / or cooling capacity for that compartment can be determined, ensuring that the airflow and / or cooling capacity flowing into the at least one compartment matches the temperature difference. This avoids ineffective heat exchange due to a mismatch between the airflow and / or cooling capacity and the cooling temperature of the heat exchanger, improving the heat exchange efficiency of the heat exchanger and increasing the cooling rate of at least one compartment in the refrigerator.

[0070] According to a third aspect of the present invention, a refrigerator control device is provided. The control device includes: a memory storing a program or instructions; and a processor executing the program or instructions stored in the memory to implement the steps of the refrigerator control method proposed in the above-described technical solution of the present invention. Therefore, it has all the beneficial technical effects of the refrigerator control method proposed in the above-described technical solution of the present invention, which will not be elaborated further here.

[0071] According to a fourth aspect of the present invention, a readable storage medium is provided on which a program or instructions are stored, which, when executed by a processor, implement the refrigerator control method as described in the above-described technical solution of the present invention. Therefore, this readable storage medium possesses all the beneficial effects of the refrigerator control method described in the above-described technical solution of the present invention, which will not be elaborated further here.

[0072] According to a fifth aspect of the present invention, a refrigerator is provided, comprising a refrigerator control device as described in the above-described technical solution of the present invention, and / or a readable storage medium as described in the above-described technical solution of the present invention. Therefore, the refrigerator possesses all the beneficial effects of the refrigerator control device and / or the readable storage medium as described in the above-described technical solution of the present invention, which will not be elaborated further here.

[0073] Additional aspects and advantages of the invention will become apparent in the following description or may be learned by practice of the invention. Attached Figure Description

[0081] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0082] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0083] The following is combined with Figures 1 to 6 The present invention provides a detailed description of a refrigerator control method, device, storage medium, and refrigerator through specific embodiments and application scenarios.

[0084] Example 1:

[0085] Figure 1 A flowchart illustrating a control method for a refrigerator according to an embodiment of the present invention is shown. The refrigerator includes a heat exchanger and multiple compartments. The control method includes:

[0086] Step S102: While the heat exchanger is operating, obtain the current cooling temperature of the heat exchanger and the room temperature of at least one of the multiple compartments.

[0087] Step S104: Adjust the airflow and / or cooling capacity entering at least one of the multiple rooms based on the current cooling temperature and room temperature.

[0088] It should be noted that the execution subject of the refrigerator control method proposed in this invention can be the refrigerator control device. In order to more clearly explain the refrigerator control method proposed in this invention, the following embodiments use the refrigerator control device as the execution subject of the refrigerator control method for illustrative purposes.

[0089] In this embodiment, the heat exchanger is used to indicate the refrigeration components of the refrigerator, such as the evaporator, condenser, etc.

[0090] Specifically, when the control device determines that the heat exchanger is in operation, it acquires in real time the surface temperature of the heat exchanger (i.e., the current cooling temperature) and the compartment temperature of at least one of the multiple compartments of the refrigerator.

[0091] Specifically, a temperature sensor is installed in the heat exchanger and in any of the multiple compartments, and the control device can obtain the current cooling temperature and the temperature of the compartment through the temperature sensor.

[0092] Furthermore, the control device adjusts the airflow and / or cooling capacity entering at least one of the multiple compartments of the refrigerator based on the real-time acquired current cooling temperature and compartment temperature. Specifically, the temperature difference between the refrigerator's compartment temperature and the refrigerator's heat exchanger can be determined based on the current cooling temperature and compartment temperature. Based on this temperature difference, the airflow and / or cooling capacity flowing into the compartment that matches the temperature difference can be determined. Then, the airflow and / or cooling capacity flowing into at least one of the multiple compartments can be adjusted based on the airflow and / or cooling capacity that matches the temperature difference.

[0093] In embodiments of the present invention, the control device can determine the temperature difference between the temperature inside at least one compartment and the cooling temperature of the heat exchanger based on the current cooling temperature and the compartment temperature. The control device can then determine the required airflow and / or cooling capacity for that compartment based on this temperature difference, ensuring that the airflow and / or cooling capacity flowing into at least one compartment matches the temperature difference. This avoids ineffective heat exchange due to a mismatch between the airflow and / or cooling capacity and the cooling temperature of the heat exchanger, thereby improving the heat exchange efficiency of the heat exchanger and increasing the cooling rate of at least one compartment in the refrigerator.

[0094] Figure 2 A flowchart illustrating a refrigerator control method according to an embodiment of the present invention is shown. The control method includes:

[0095] Step S202: Determine the adjustment sequence of air volume and / or cooling capacity for multiple rooms based on their adjustment priority levels.

[0096] Step S204: While the heat exchanger is operating, obtain the current cooling temperature of the heat exchanger and the chamber temperature of at least one of the multiple chambers;

[0097] Step S206: Adjust the airflow and / or cooling capacity entering at least one of the multiple rooms based on the current cooling temperature and room temperature.

[0098] In this embodiment, before the control device obtains the current cooling temperature of the heat exchanger surface and the compartment temperature of at least one of the multiple compartments of the refrigerator through the temperature sensor, the control device also needs to determine the specific order of adjusting the air volume and / or cooling capacity of the multiple compartments of the refrigerator according to the preset adjustment priority level.

[0099] Specifically, since a refrigerator may include multiple compartments, and the heat exchanger cannot simultaneously adjust the temperature of the multiple compartments to the target temperature set by the user, the control device needs to determine the specific adjustment sequence of the multiple compartments according to the pre-set adjustment priority level.

[0100] Specifically, since the refrigerated compartment is opened and closed more frequently, its adjustment priority can be set to the highest level; or, since users pay more attention to the food stored in the frozen compartment, its adjustment priority can be set to the highest level. In essence, the adjustment priority level is set according to the user's requirements, and this invention does not impose any limitations on it.

[0101] In this embodiment, before obtaining the current cooling temperature and the compartment temperature, the control device needs to determine the adjustment order of any one of the multiple compartments of the refrigerator according to a preset adjustment priority level. This allows subsequent steps to quickly adjust the temperature of the compartment with the higher priority to the user-set target temperature according to this adjustment order, improving user satisfaction.

[0102] In the above embodiments, the multiple compartments include at least one refrigerator compartment and at least one freezer compartment, and the adjustment priority of at least one refrigerator compartment is higher than that of at least one freezer compartment.

[0103] In this embodiment, the refrigerator includes at least one refrigerator compartment and at least one freezer compartment. Specifically, in adjusting the priority level, the at least one refrigerator compartment has a higher priority level than the at least one freezer compartment.

[0104] Specifically, since the refrigerated compartments open and close more frequently, in order to ensure the preservation capacity of the refrigerated compartments, the priority level of the refrigerated compartments needs to be set above that of the freezer compartments in the adjustment priority level.

[0105] In this embodiment, the refrigerator's multiple compartments include at least one refrigeration type compartment (i.e., the aforementioned refrigerator compartment) and at least one freezing type compartment (i.e., the aforementioned freezer compartment). During temperature adjustment, the priority of at least one refrigerator compartment is higher than that of at least one freezer compartment. This avoids the situation where the refrigerator compartment's preservation ability is weak due to frequent opening and closing of at least one refrigerator compartment.

[0106] Figure 3 A flowchart illustrating a control method for a refrigerator according to an embodiment of the present invention is shown. The refrigerator includes a heat exchanger and multiple compartments. The control method includes:

[0107] Step S302: While the heat exchanger is operating, obtain the current cooling temperature of the heat exchanger and the room temperature of at least one of the multiple compartments;

[0108] Step S304: Adjust the air volume and / or cooling capacity entering at least one of the multiple rooms according to the current cooling temperature and room temperature;

[0109] Step S306: If the rate of change of the difference between the room temperature of at least one room and the current cooling temperature exceeds a predetermined threshold, adjust the air volume and / or cooling capacity entering at least one room.

[0110] Step S308: If the temperature of at least one room changes and the rate of change exceeds a predetermined threshold, adjust the airflow and / or cooling capacity entering at least one room.

[0111] In this embodiment, the control device adjusts the airflow and / or cooling capacity in at least one of the multiple compartments flowing into the refrigerator based on the current cooling temperature and the compartment temperature. This can be achieved by the control device determining the temperature difference between the compartment temperature and the current cooling temperature in the at least one compartment, and then comparing the rate of change of the temperature difference with a preset threshold.

[0112] Specifically, when the control device determines that the rate of change of the temperature difference between the above-mentioned room temperature and the above-mentioned current cooling temperature exceeds a preset threshold, the control device determines that it is necessary to adjust the air volume and / or cooling capacity flowing into at least one room.

[0113] Specifically, if the rate of change of the temperature difference between the above-mentioned room temperature and the above-mentioned current cooling temperature exceeds a preset threshold, it indicates that the temperature difference between the room temperature being adjusted and the cooling temperature has changed. At this time, in order to ensure that the air volume and / or cooling capacity flowing into the room matches the above-mentioned temperature difference and to avoid ineffective heat exchange, the control device needs to adjust the air volume and / or cooling capacity flowing into the room.

[0114] Specifically, the control device may adjust the airflow and / or cooling capacity in at least one of the multiple compartments of the refrigerator based on the current cooling temperature and the compartment temperature. Alternatively, the control device may monitor the compartment temperature in at least one of the multiple compartments in real time, and when the compartment temperature changes and the rate of change exceeds a predetermined threshold, determine that the airflow and / or cooling capacity in at least one compartment needs to be adjusted.

[0115] Specifically, if the rate of change of temperature in at least one monitored room exceeds a predetermined threshold, it indicates that the temperature in at least one room is too low or too high. In this case, in order to ensure that the temperature in at least one room is within the range set by the user, the control device needs to adjust the airflow and / or cooling capacity flowing into the room.

[0116] In this embodiment, the control device can determine whether to adjust the airflow and / or cooling capacity flowing into the at least one compartment based on changes in the compartment temperature or changes in the temperature difference between the compartment temperature and the current cooling temperature. This ensures that during the temperature adjustment of multiple compartments of the refrigerator, the airflow and / or cooling capacity flowing into that compartment always matches the temperature difference, guaranteeing that the temperature in the at least one compartment remains within the user-set range and ensuring the preservation capability of at least one of the refrigerator's multiple compartments.

[0117] Figure 4 A flowchart illustrating a control method for a refrigerator according to an embodiment of the present invention is shown. The refrigerator includes a heat exchanger and multiple compartments. The control method includes:

[0118] Step S402: While the heat exchanger is operating, obtain the current cooling temperature of the heat exchanger and the room temperature of at least one of the multiple compartments;

[0119] Step S404: Adjust the air volume and / or cooling capacity entering at least one of the multiple rooms according to the current cooling temperature and room temperature;

[0120] Step S406: If the rate of change of the difference between the room temperature of at least one room and the current cooling temperature is greater than or equal to a first change threshold, or if the increase in the room temperature of at least one room is greater than or equal to a first temperature threshold, increase the air volume and / or cooling capacity of at least one room.

[0121] In this embodiment, the control device first determines the temperature difference between the room temperature in the at least one room and the current cooling temperature, and compares the rate of change of the temperature difference with a first change threshold, or determines the temperature increase in the room temperature in the at least one room and compares the temperature increase with a first temperature threshold.

[0122] Specifically, when the control device determines that the rate of change of the temperature difference between the above-mentioned room temperature and the above-mentioned current cooling temperature is greater than or equal to the above-mentioned first change threshold, the control device determines that it is necessary to increase the air volume and / or cooling capacity flowing into at least one room.

[0123] Specifically, if the rate of change of the temperature difference between the above-mentioned room temperature and the above-mentioned current cooling temperature is greater than or equal to the above-mentioned first change threshold, it indicates that the temperature difference between the at least one room being adjusted and the cooling temperature has become smaller. At this time, increasing the airflow into the room will not result in ineffective heat exchange. In order to accelerate the cooling rate of the at least one room, the control device needs to increase the airflow and / or cooling capacity into the at least one room.

[0124] Specifically, when the control device determines that the temperature increase of the aforementioned compartment is greater than or equal to the aforementioned first temperature threshold, the control device determines that it is necessary to increase the airflow and / or cooling capacity flowing into at least one compartment.

[0125] Specifically, if the temperature increase of at least one monitored compartment is greater than or equal to the first temperature threshold, it may indicate that during the process of the control device adjusting the temperature of a compartment with a high priority, the temperature increase of at least one compartment with a low priority exceeds the threshold, that is, the temperature of at least one compartment with a low priority is too high. In this case, the control device needs to increase the airflow and / or cooling capacity into the compartment in order to quickly adjust the temperature in the compartment to the normal operating temperature.

[0126] Specifically, if the temperature increase of at least one of the monitored compartments is greater than or equal to the first temperature threshold, it may also indicate that during the stable operation of the refrigerator, the temperature in at least one compartment suddenly rises due to the user storing or taking out food. In this case, the control device needs to increase the airflow and / or cooling capacity into the compartment to quickly adjust the temperature in the compartment to the normal operating temperature.

[0127] In this embodiment, the control device can determine whether it is necessary to increase the airflow and / or cooling capacity flowing into the at least one compartment based on the increase in the temperature of the compartment in the at least one compartment, or based on the rate of change of the temperature difference between the compartment temperature and the current cooling temperature. This avoids ineffective heat exchange and accelerates the cooling rate of at least one compartment during the temperature adjustment of multiple compartments of the refrigerator; it also ensures the preservation capacity of compartments with lower temperature priority during temperature adjustment of compartments with higher priority; and it can quickly restore the temperature of compartments that have suddenly risen to normal levels during stable refrigerator operation.

[0128] In the above embodiments, increasing the air volume and / or cooling capacity of at least one room includes at least one of the following or a combination thereof: directly increasing the air volume and / or cooling capacity of at least one room; closing or reducing the air volume and / or cooling capacity of one or more rooms other than at least one room.

[0129] In this embodiment, the control device increases the airflow and / or cooling capacity flowing into the at least one compartment in one or more of the following ways: First, the control device directly increases the airflow and / or cooling capacity flowing into the at least one compartment; Second, the control device closes or reduces the airflow and / or cooling capacity flowing into multiple or one compartment of the refrigerator, excluding the at least one compartment.

[0130] Specifically, for refrigerators that can directly adjust airflow and / or cooling capacity, the control device can directly control the air supply equipment and the aforementioned heat exchanger to increase the airflow and / or cooling capacity flowing into the at least one compartment. For some refrigerators, since the airflow and / or cooling capacity flowing into the refrigerator compartment is fixed, the control device needs to increase the airflow and / or cooling capacity flowing into the at least one compartment by closing or reducing the airflow and / or cooling capacity flowing into multiple or one compartment in multiple compartments of the refrigerator, excluding the at least one compartment.

[0131] For example, for a refrigerator that can directly adjust the air volume and / or cooling capacity, the control device can also increase the air volume and / or cooling capacity flowing into the at least one compartment by directly increasing the air volume and / or cooling capacity flowing into the at least one compartment and closing or reducing the air volume and / or cooling capacity flowing into multiple or one compartment of the refrigerator in addition to the at least one compartment.

[0132] In the above embodiments, when the airflow and / or cooling capacity of one or more rooms in other rooms besides at least one room are closed or reduced, the rate of temperature rise in one or more rooms in other rooms is detected, and / or the rate of change of the temperature difference between the room temperature of one or more rooms in other rooms and the current cooling temperature is detected.

[0133] In this embodiment, when the control device increases the airflow and / or cooling capacity flowing into the at least one compartment, and it is necessary to close or reduce the airflow and / or cooling capacity flowing into multiple or one compartment of the refrigerator in addition to the at least one compartment, the control device also needs to detect the compartment temperature of multiple compartments or one compartment of the multiple compartments of the refrigerator in addition to the at least one compartment.

[0134] Furthermore, the control device calculates the rate of temperature rise of multiple rooms or one room based on the detected room temperature, and / or calculates the rate of change of the temperature difference between the current cooling temperature and the room temperatures of multiple rooms or one room, that is, calculates the rate of temperature rise in the room with the air volume and / or cooling capacity reduced in the multiple rooms, and / or calculates the rate of change of the temperature difference between the current cooling temperature and the room with the air volume and / or cooling capacity reduced in the multiple rooms.

[0135] Specifically, based on the aforementioned temperature rise rate and / or the aforementioned temperature difference change rate, the specific temperature changes in the compartments of the refrigerator with the airflow and / or cooling capacity reduced or closed can be determined, so that in subsequent steps, when the temperature in a compartment is too high, the airflow and / or cooling capacity flowing into that compartment can be adjusted in a timely manner.

[0136] In this embodiment, when the control device increases the airflow and / or cooling capacity flowing into the at least one compartment of the refrigerator by closing or reducing the airflow and / or cooling capacity flowing into the at least one compartment, the control device needs to detect and calculate the temperature rise rate in the compartments where the airflow and / or cooling capacity is closed or reduced, and / or calculate the rate of change of the temperature difference between the current cooling temperature of the heat exchanger and the temperature difference in the compartments where the airflow and / or cooling capacity is closed or reduced, so that in subsequent steps, the airflow and / or cooling capacity flowing into the compartment can be adjusted in a timely manner when the temperature in the compartment is too high.

[0137] In the above embodiments, if the temperature rise rate of one or more other compartments is detected to be greater than or equal to a predetermined rise rate threshold, and / or the rate of change of the difference is greater than or equal to a rate of change threshold, the air volume and / or cooling capacity of the corresponding compartment are adjusted.

[0138] In this embodiment, if the temperature rise rate in the multiple compartments where the airflow and / or cooling capacity is closed or reduced is greater than or equal to a predetermined rise threshold, and / or if the rate of change of the difference between the current cooling temperature of the heat exchanger and the temperature in the multiple compartments where the airflow and / or cooling capacity is closed or reduced is greater than or equal to a rate of change threshold, the control device needs to adjust the airflow and / or cooling capacity flowing into the corresponding compartments in the multiple compartments where the airflow and / or cooling capacity is closed or reduced.

[0139] Specifically, if the temperature rise rate is greater than or equal to the predetermined rise rate threshold, it indicates that the temperature in the compartment where the air volume and / or cooling capacity is closed or reduced is too high. In this case, the control device needs to adjust the air volume and / or cooling capacity flowing into the corresponding compartment to reduce the temperature in the corresponding compartment in order to ensure the preservation capacity of the corresponding compartment.

[0140] Specifically, if the rate of change of the temperature difference is greater than or equal to the rate of change threshold, it indicates that in the multiple rooms where the air volume and / or cooling volume are closed or reduced, the air volume and / or cooling volume flowing into the corresponding room does not match the temperature difference. In this case, in order to avoid ineffective heat exchange, the control device needs to adjust the air volume and / or cooling volume flowing into the corresponding room.

[0141] In this embodiment, when the control device detects and calculates that the temperature rise rate is greater than or equal to the predetermined rise rate threshold, and / or the temperature difference change rate is greater than or equal to the change rate threshold, the control device needs to adjust the airflow and / or cooling capacity flowing into the corresponding compartment. This lowers the temperature in the corresponding compartment, ensuring its preservation capacity; and / or ensures that the airflow and / or cooling capacity flowing into the corresponding compartment matches the temperature difference, thus preventing ineffective heat exchange within the refrigerator compartment.

[0142] In the above embodiments, the method of adjusting the air volume and / or cooling capacity entering each compartment includes at least one of the following or a combination thereof: adjusting the opening degree of the damper of each compartment; adjusting the power of the refrigerator's heat exchanger; adjusting the speed of the refrigerator's fan; controlling the on and off of at least one of the multiple fans when the refrigerator includes multiple fans; and controlling the speed of at least one of the multiple fans when the refrigerator includes multiple fans.

[0143] In this embodiment, the control device can adjust the airflow and / or cooling capacity of any one of the multiple compartments flowing into the refrigerator through one or more of the following methods in combination: first, adjusting the opening degree of the damper corresponding to each of the multiple compartments; second, adjusting the operating power of the heat exchanger; third, adjusting the rotational speed of the refrigerator fan; fifth, when there are multiple fans in the refrigerator, controlling at least one of the multiple fans to turn on or off; sixth, when there are multiple fans in the refrigerator, adjusting the rotational speed of at least one of the multiple fans.

[0144] Furthermore, refrigerators are generally equipped with regulating valves, which can be used to regulate the airflow to the heat exchanger. The control device can also adjust the cooling capacity of any one of the multiple compartments of the refrigerator by adjusting the opening of the regulating valve.

[0145] Furthermore, the control device can also regulate the amount of cold air flowing into any of the multiple compartments of the refrigerator by adjusting the speed of the refrigerator compressor motor.

[0146] In the above embodiments, when the refrigerator includes multiple fans, at least one of the multiple fans provides airflow to at least one of the multiple compartments.

[0147] In this embodiment, when it is determined that the refrigerator is equipped with multiple fans for adjusting airflow, at least one of the multiple fans can provide airflow to at least one of the multiple compartments.

[0148] Specifically, each fan corresponds one-to-one with one of the aforementioned rooms, meaning that one fan provides airflow to one corresponding room.

[0149] Furthermore, the aforementioned multiple fans and multiple compartments may not correspond one-to-one, but rather to the air ducts connected to the air dampers of the multiple compartments. That is, the multiple compartments provide airflow to the air ducts, and the air ducts provide airflow to the multiple compartments through the air dampers.

[0152] In this embodiment, the heat exchanger is used to indicate the refrigeration components of the refrigerator, such as the evaporator, condenser, etc.

[0153] Specifically, when it is determined that the heat exchanger is in operation, the acquisition module 502 acquires in real time the surface temperature of the heat exchanger (i.e., the current cooling temperature) and the compartment temperature of at least one of the multiple compartments of the refrigerator.

[0154] Specifically, a temperature sensor is installed in the heat exchanger and in any of the multiple compartments, and the acquisition module 502 can acquire the current cooling temperature and the temperature of the compartment through the temperature sensor.

[0155] Furthermore, the processing module 504 adjusts the airflow and / or cooling capacity entering at least one of the multiple compartments of the refrigerator based on the real-time acquired current cooling temperature and compartment temperature. Specifically, the processing module 504 can determine the temperature difference between the refrigerator's compartment temperature and the refrigerator's heat exchanger's cooling temperature based on the current cooling temperature and compartment temperature. The processing module can determine the airflow and / or cooling capacity flowing into the compartment that matches the temperature difference based on this temperature difference, and then adjust the airflow and / or cooling capacity flowing into at least one of the multiple compartments based on the airflow and / or cooling capacity that matches the temperature difference.

[0156] In an embodiment of the present invention, the processing module 504, based on the current cooling temperature and the compartment temperature, can determine the temperature difference between the temperature inside at least one compartment and the cooling temperature of the heat exchanger. Based on this temperature difference, the processing module 504 can determine the specific airflow and / or cooling capacity required for that compartment, ensuring that the airflow and / or cooling capacity flowing into at least one compartment matches the temperature difference. This avoids ineffective heat exchange due to a mismatch between the airflow and / or cooling capacity and the cooling temperature of the heat exchanger, improving the heat exchange efficiency of the heat exchanger and increasing the cooling rate of at least one of the multiple compartments of the refrigerator.

[0160] In the above embodiments, the processing module 504 is further configured to increase the air volume and / or cooling capacity of at least one room when the rate of change of the difference between the room temperature of at least one room and the current cooling temperature is greater than or equal to a first change threshold, or when the increase in the room temperature of at least one room is greater than or equal to a first temperature threshold.

[0161] In the above embodiments, the processing module 504 increases the air volume and / or cooling capacity of at least one room by at least one of the following or a combination thereof: directly increasing the air volume and / or cooling capacity of at least one room; or closing or reducing the air volume and / or cooling capacity of one or more rooms other than at least one room.

[0162] In the above embodiments, the processing module 504 is further configured to detect the rate of temperature rise in one or more other rooms, and / or detect the rate of change of the temperature difference between the room temperature of one or more other rooms and the current cooling temperature, when the air volume and / or cooling capacity of one or more rooms in other rooms are closed or reduced.

[0163] In the above embodiments, the processing module 504 is further configured to adjust the air volume and / or cooling capacity of the corresponding room when it is detected that the temperature rise rate of one or more rooms in other rooms is greater than or equal to a predetermined rise rate threshold, and / or the rate of change of the difference is greater than or equal to a rate of change threshold.

[0164] In the above embodiments, the processing module 504 adjusts the air volume and / or cooling capacity entering each compartment by at least one or a combination of the following: adjusting the opening degree of the damper of each compartment; adjusting the power of the refrigerator's heat exchanger; adjusting the speed of the refrigerator's fan; controlling the on and off of at least one of the multiple fans when the refrigerator includes multiple fans; and controlling the speed of at least one of the multiple fans when the refrigerator includes multiple fans.
