Technical Field

[0001] The present invention relates to the technical field of refrigeration, and in particular to a control method of a refrigerator and a refrigerator. Background Art

[0002] As a common household appliance, refrigerators can store items at low temperatures. When a power outage occurs in a refrigerator, the storage compartment of the refrigerator loses its low temperature environment, and the humidity in the storage compartment of the refrigerator becomes high, causing the food stored in the refrigerator to easily deteriorate. At present, there is a solution in the prior art to maintain the refrigeration work of the refrigerator after a power outage by setting a backup power supply for the refrigerator.

[0003] However, since the backup power supply needs to power the entire refrigeration system of the refrigerator, the refrigerator structure is complex, the cost is high, and the backup power supply capacity is required to be high. Summary of the invention

[0010] Optionally, the step of controlling the power storage module to supply power to the electromagnetic coil includes:

[0011] The power storage module is controlled to supply power to the electromagnetic coil according to a preset power supply mode, wherein the power supply mode enables the power storage module to supply power to the electromagnetic coil at intervals.

[0012] Optionally, the refrigerator is pre-configured with at least one set of correspondences, the correspondences comprising a type of food and a corresponding preset power supply mode;

[0014] Get the types of food in the storage room;

[0015] The power supply mode of the power storage module is determined according to the type of food and the corresponding relationship.

[0016] Optionally, the corresponding relationship includes one or more of the following groups:

[0017] The food type is dry goods, and the corresponding power supply mode makes the interval between two consecutive power supplies of the power storage module less than or equal to 48 hours;

[0018] The food type is meat, and the corresponding power supply mode makes the interval between two consecutive power supplies of the power storage module less than or equal to 6 hours;

[0019] The food type is vegetables, and the corresponding power supply mode makes the interval between two consecutive power supplies of the power storage module less than or equal to 12 hours;

[0020] The type of food is berries, and the corresponding power supply mode makes the interval time between two consecutive power supplies of the power storage module less than or equal to 7 hours.

[0021] Optionally, the step of determining the power supply mode of the power storage module according to the food type and the corresponding relationship includes:

[0022] Read all corresponding power supply modes according to the acquired food types;

[0023] A power supply mode that makes the interval between the last two power supplies by the power storage module the shortest is selected from all the acquired power supply modes as the power supply mode finally used.

[0024] Optionally, the power supply mode is configured so that the power supply time of the power storage module becomes longer and longer each time; or,

[0025] The power supply mode is configured so that the time interval between two consecutive power supplies from the power storage module becomes shorter and shorter.

[0026] Optionally, the power storage module is configured so that the electromagnetic coil generates an alternating magnetic field or a pulsed magnetic field.

[0027] Optionally, the control method further includes:

[0032] Determine whether the power level is less than or equal to a preset power level threshold;

[0033] If the power level is less than or equal to the preset power threshold, the power storage module is charged until it is fully charged.

[0034] In another aspect of the present invention, a refrigerator is provided, comprising:

[0035] A controller comprises a memory and a processor, wherein the memory stores a machine executable program, and when the machine executable program is executed by the processor, the control method of the refrigerator according to any one of the above items is implemented.

[0036] The control method and refrigerator of the present invention detects power outages in the refrigerator by arranging an electromagnetic coil and a power storage module in the storage compartment, determines whether the power outage time reaches a preset threshold, and controls the power storage module to supply power to the electromagnetic coil if the power outage time reaches the preset threshold. That is to say, after a power outage occurs in the refrigerator, the power storage module can be used to supply power to the electromagnetic coil, so that the electromagnetic coil generates a magnetic field, and the magnetic field can sterilize the food, which helps to extend the shelf life of the food when the refrigerator is powered off. Compared with using a storage power supply to power the entire refrigerator's refrigeration system, since only the storage module needs to be used to power the electromagnetic coil, it helps to simplify the structure, and the capacity requirement of the storage module is relatively low, which helps to reduce costs. In addition, when the refrigerator is powered on and cooled normally, the electromagnetic coil can also use the main power supply of the refrigerator to generate a magnetic field, which plays an auxiliary role in the storage of food and improves the preservation effect of food.

[0037] Furthermore, the control method of the refrigerator and the refrigerator of the present invention control the power storage module to supply power to the electromagnetic coil according to a preset power supply mode, and the power supply mode enables the power storage module to supply power to the electromagnetic coil at intervals, that is, the power storage module supplies power to the electromagnetic coil at intervals during the power outage, that is, supplies power for a period of time, stops supplying power and waits for a certain period of time, and then supplies power again, and so on, until the power of the refrigerator is restored. On the one hand, by supplying power to the electromagnetic coil at intervals, the unit time consumption of the power storage module can be reduced on the basis of ensuring the sterilization effect of the electromagnetic coil on the food, so that the electromagnetic coil can still generate a magnetic field after a longer power outage of the refrigerator, which is beneficial to further extend the preservation time of the food. On the other hand, the electromagnetic coil generates a magnetic field at intervals, so that the storage compartment has a changing magnetic field environment, which can obtain a better sterilization effect.

[0048] It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present invention, rather than all embodiments of the present invention, and these embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0049] It should be noted that the logic and / or steps represented in the flowchart or described in other ways herein, for example, can be considered as a sequenced list of executable instructions for implementing logical functions, and can be specifically implemented in any computer-readable medium for use by an instruction execution system, device or equipment (such as a computer-based system, a system including a processor, or other system that can fetch instructions from an instruction execution system, device or equipment and execute instructions), or used in combination with these instruction execution systems, devices or equipment.

[0050] The flow chart provided by the present invention is not intended to indicate that the operation of the method will be performed in any particular order, or all operations of the method are included in all every case. In addition, the method may include additional operations. Within the scope of the technical thinking provided by the present embodiment method, additional changes can be made to the above method.

[0051] like Figure 1 As shown, in one embodiment, the refrigerator 1 includes a housing 100, an electromagnetic coil 200 and a power storage module 300. The housing 100 is formed with a storage compartment 101. The electromagnetic coil 200 is used to generate a magnetic field in the storage compartment 101. The power storage module 300 is used to supply power to the electromagnetic coil 200. Specifically, the electromagnetic coil 200 can be arranged in the storage compartment 101 or outside the storage compartment 101, and can generate a magnetic field that can cover the storage compartment 101. The power storage module 300 is used to cool the electromagnetic coil during a power outage, that is, under normal circumstances, the electromagnetic coil 200 is powered by the main power supply of the refrigerator. When the main power supply of the refrigerator is disconnected, such as a power outage or a failure of the refrigerator plug, the power storage module 300 supplies power to the electromagnetic coil 200.

[0052] like Figure 2 As shown, the refrigerator 1 further includes a controller 10, and the controller 10 includes a memory 11 and a processor 12. The memory 11 stores a machine executable program, and when the machine executable program is executed by the processor 12, the refrigerator control method of any of the following embodiments is implemented.

[0053] like Figure 3 As shown, in one embodiment, the control method of the refrigerator generally includes:

[0054] Step S301, it is detected that the refrigerator is powered off. Specifically, it is detected that the refrigerator plug no longer transmits current to the refrigerator, such as a power outage or the refrigerator plug and socket are electrically disconnected.

[0055] Step S302, judging whether the power-off time reaches a preset threshold. Specifically, the time is counted from the moment when the refrigerator is powered off, and the accumulated time is compared with the preset threshold to judge whether the accumulated power-off time reaches the preset threshold. The preset threshold is greater than 0, for example, it can be 4 hours, 5 hours or 6 hours, etc., and the user can set and modify it according to actual needs.

[0056] Step S303: If the power-off time reaches a preset threshold, the power storage module is controlled to supply power to the electromagnetic coil. Specifically, the power storage module is used to supply power to the electromagnetic coil, so that the electromagnetic coil generates a magnetic field, thereby sterilizing the food.

[0057] In the solution of this embodiment, by setting an electromagnetic coil and a power storage module in the storage compartment, a power outage of the refrigerator is detected, and it is determined whether the power outage time reaches a preset threshold. If the power outage time reaches the preset threshold, the power storage module is controlled to supply power to the electromagnetic coil. That is to say, after the refrigerator is powered off, the power storage module can be used to power the electromagnetic coil, so that the electromagnetic coil generates a magnetic field, and the magnetic field can sterilize the food, which helps to extend the shelf life of the food when the refrigerator is powered off. Compared with using a storage power supply to power the entire refrigerator's refrigeration system, because only the storage module needs to be used to power the electromagnetic coil, it helps to simplify the structure, and the capacity requirement of the storage module is low, which is conducive to reducing costs. In addition, when the refrigerator is powered on and refrigerated normally, the electromagnetic coil can also use the main power supply of the refrigerator to generate a magnetic field, which plays an auxiliary role in the storage of food and improves the preservation effect of food.

[0058] In addition, by making the preset threshold greater than 0, a certain cache waiting time can be provided to avoid starting the power storage module when the refrigerator is powered off for a short time and will not affect the food, thereby avoiding the trouble of multiple short-term power supply mode conversions and the waste of power from the power storage module.

[0059] It should be noted that in some other embodiments, the preset threshold may also be 0.

[0060] like Figure 4 As shown, in one embodiment, the step of controlling the power storage module to supply power to the electromagnetic coil includes: controlling the power storage module to supply power to the electromagnetic coil according to a preset power supply mode. In this embodiment, the control method of the refrigerator generally includes:

[0061] Step S401: Detect that a power outage occurs in the refrigerator.

[0062] Step S402, determining whether the power-off time reaches a preset threshold.

[0063] Step S403, if the power-off time reaches the preset threshold, the power storage module is controlled to supply power to the electromagnetic coil according to the preset power supply mode, and the power supply mode enables the power storage module to supply power to the electromagnetic coil at intervals. Specifically, the power storage module supplies power to the electromagnetic coil at intervals during the power outage, that is, supplies power for a period of time, stops supplying power and waits for a certain period of time, and then supplies power again, and so on and so forth until the power of the refrigerator is restored. Specifically, when the power-off time reaches the preset threshold, the power storage module supplies power to the electromagnetic coil for a period of time for the first time, then stops supplying power for a period of time, and then supplies power to the electromagnetic coil for a period of time for the second time, and thus supplies power to the electromagnetic coil in an intermittent manner.

[0064] It should be noted that, in one embodiment, the power supply mode makes the power supply time and interval time of the power storage module each time both be fixed values. Exemplarily, the preset threshold is a hour, and the power supply mode is configured so that the power supply time of the power storage module is m hours and the interval time is n hours. When a power outage in the refrigerator is detected, the power outage time of the refrigerator is recorded. When the power outage time reaches a hour, the power storage module is controlled to supply power to the electromagnetic coil for the first time. When the first power supply time reaches m hours, the power storage module is controlled to stop supplying power to the electromagnetic coil. When the power supply stop time reaches n hours, the power storage module is controlled to supply power to the electromagnetic coil again. When the power supply time reaches m hours, the power storage module is controlled to stop supplying power to the electromagnetic coil again. This goes back and forth. If a call from the refrigerator is detected during this period, the power storage module is controlled to stop supplying power to the electromagnetic coil and use the main power supply of the refrigerator to supply power to the electromagnetic coil.

[0065] It should be noted that, in one embodiment, the power supply mode makes the power supply time or interval time of the power storage module each time a variable value. For example, the power supply mode is configured to make the power supply time of the power storage module each time longer and longer. Specifically, the power supply mode can be configured to make the power supply time of the power storage module each time decrease according to a fixed value. Exemplarily, the preset threshold is A hours, and the power supply mode is configured to make the first power supply time of the power storage module M hours, the interval time is N hours, and the decreasing fixed value is m. When the refrigerator is detected to be powered off, the power off time of the refrigerator is recorded. When the power off time reaches A hours, the power storage module is controlled to supply power to the electromagnetic coil for the first time. When the first power supply time reaches M hours, the power storage module is controlled to stop supplying power to the electromagnetic coil. When the power supply stop time reaches N hours, the power storage module is controlled to supply power to the electromagnetic coil again. When the power supply time reaches (Mm) hours, the power storage module is controlled to stop supplying power to the electromagnetic coil again. This goes back and forth. If a call is detected from the refrigerator during this period, the power storage module is controlled to stop supplying power to the electromagnetic coil and use the main power supply of the refrigerator to supply power to the electromagnetic coil. If the power supply time is less than or equal to 0, power supply is performed according to a preset method. Specifically, the preset method can be to restart a cycle with the first power supply time, or to use the last power supply time as a fixed power supply time, or to use a preset value as a fixed power supply time, etc.

[0066] In addition, the power supply mode makes the power supply time or interval time of the power storage module each time a variable value, or the power supply mode is configured so that the time interval between two adjacent power supplies of the power storage module becomes shorter and shorter. Specifically, the power supply mode can be configured so that the power supply time of the power storage module decreases according to a fixed value each time. Exemplarily, the preset threshold is A hours, and the power supply mode is configured so that the first power supply time of the power storage module is M hours, the interval time is N hours, and the decreasing fixed value is n. When the refrigerator is detected to be powered off, the power off time of the refrigerator is recorded. When the power off time reaches A hours, the power storage module is controlled to supply power to the electromagnetic coil for the first time. When the first power supply time reaches M hours, the power storage module is controlled to stop supplying power to the electromagnetic coil. When the power supply stop time reaches N hours, the power storage module is controlled to supply power to the electromagnetic coil again. When the power supply time reaches M hours, the power storage module is controlled to stop supplying power to the electromagnetic coil again. When the power supply stop time reaches (Nn) hours, the power storage module is controlled to supply power to the electromagnetic coil again, and so on. If a call is detected during the refrigerator, the power storage module is controlled to stop supplying power to the electromagnetic coil and use the main power supply of the refrigerator to supply power to the electromagnetic coil. If the power supply stop time is less than or equal to 0, the electromagnetic coil will continue to be powered without stopping.

[0067] In the scheme of this embodiment, the power storage module is controlled to supply power to the electromagnetic coil according to a preset power supply mode. The power supply mode enables the power storage module to supply power to the electromagnetic coil at intervals, that is, the power storage module supplies power to the electromagnetic coil at intervals during the power outage, that is, supplies power for a period of time, stops supplying power and waits for a certain period of time, and then supplies power again, and so on, until the power of the refrigerator is restored. On the one hand, by supplying power to the electromagnetic coil at intervals, the unit time consumption of the power storage module can be reduced on the basis of ensuring the sterilization effect of the electromagnetic coil on the food, so that the electromagnetic coil can still generate a magnetic field after a longer power outage of the refrigerator, which is conducive to further extending the preservation time of the food. On the other hand, the electromagnetic coil generates a magnetic field at intervals, so that the storage compartment has a changing magnetic field environment, which can obtain a better sterilization effect.

[0068] It should be noted that, in some other embodiments, the power supply mode may also make the power supply time of the power storage module longer and longer each time and make the time interval between two adjacent power supplies of the power storage module shorter and shorter.

[0069] It should be noted that, in some other embodiments, the power storage module may also be controlled to continuously supply power to the electromagnetic coil until the power is exhausted.

[0070] like Figure 5As shown, in one embodiment, the refrigerator is pre-configured with at least one set of correspondences, the correspondences including a type of food and a corresponding preset power supply mode, and all power supply modes are such that the power storage module supplies power to the electromagnetic coil at intervals. After detecting that the refrigerator is powered off, the steps include: obtaining the type of food in the storage compartment; and determining the power supply mode of the power storage module according to the type of food and the correspondence.

[0071] In this embodiment, the control method of the refrigerator generally includes:

[0072] Step S501: Detect that a power outage occurs in the refrigerator.

[0073] Step S502, obtaining the types of food in the storage compartment. Specifically, when the refrigerator is powered off, obtaining the types of food stored in the storage compartment when the power is off.

[0074] Reference Figure 6 As shown, specifically, the refrigerator control method also includes:

[0075] Step S601, obtaining an event of food being put into a storage room. Specifically, an infrared detector can be used to detect whether food is put into the storage room. When the infrared detector detects that food is put into the storage room, it is determined to obtain an event of food being put into the storage room.

[0076] Step S602, obtaining and recording the types of food put in. Specifically, when food is put into the storage compartment, the refrigerator obtains and records the types of food put into the storage compartment. For example, the types of food directly input by the user may be obtained and recorded, or an image acquisition device may be used to capture an image of the food put into the storage compartment, and then the types of food are obtained and recorded based on the image.

[0077] Step S503, determine the power supply mode of the power storage module according to the food type and the corresponding relationship. Referring to the above, the power supply mode enables the power storage module to supply power to the electromagnetic coil at intervals. That is to say, the refrigerator pre-stores a variety of food types and the power supply mode corresponding to each food type. The power supply mode is to enable the power storage module to supply power to the electromagnetic coil at intervals, but the power supply time or the power supply stop time between two adjacent power supplies of the power supply mode corresponding to each food type is different.

[0078] Specifically, the corresponding relationship of the refrigerator includes the following groups:

[0079] The food type is dry goods, and the corresponding power supply mode makes the interval between two consecutive power supplies of the power storage module less than or equal to 48 hours. For example, the interval between two consecutive power supplies is 48 hours, 45 hours, 30 hours, 24 hours, etc.

[0080] The food type is meat, and the corresponding power supply mode makes the interval between two adjacent power supplies of the power storage module less than or equal to 6 hours. For example, the interval between two adjacent power supplies is 6 hours, 5 hours, 3 hours, 2 hours, etc.

[0081] The food type is vegetables, and the corresponding power supply mode makes the interval between two adjacent power supplies of the power storage module less than or equal to 12 hours. For example, the interval between two adjacent power supplies is 12 hours, 11 hours, 10 hours, 7 hours, etc.

[0082] The food type is berries, and the corresponding power supply mode makes the interval between two adjacent power supplies of the power storage module less than or equal to 7 hours. For example, the interval between two adjacent power supplies is 6 hours, 4 hours, 3.5 hours, 1 hour, etc.

[0083] Reference Figure 7 Specifically, the step of determining the power supply mode of the power storage module according to the food type and the corresponding relationship includes:

[0084] Step S701, read all corresponding power supply modes according to the acquired food type. Specifically, if only one food type is acquired, all the read power supply modes are the corresponding one power supply mode. If multiple food types are acquired, all the read power supply modes are the corresponding multiple power supply modes.

[0085] Step S702, from all the acquired power supply modes, the power supply mode that makes the interval between the first two power supplies of the power storage module the shortest is selected as the power supply mode used finally. Specifically, if only one power supply mode is read, the power supply mode is used to control the power storage module to supply power. If multiple power supply modes are acquired, the time intervals between the first two power supplies of the multiple power supply modes are compared, and the shortest power supply mode is selected as the power supply mode used finally.

[0086] Exemplarily, the interval time of the power supply mode corresponding to meat is 6 hours, the interval time of the power supply mode corresponding to dry goods is 48 hours, the interval time of the power supply mode corresponding to vegetables is 12 hours, and the interval time of the power supply mode corresponding to berries is 6 hours.

[0087] In one example, it is obtained that there are two types of food ingredients, meat and dry goods, in the storage room, and then two power supply modes are obtained. The interval time of the power supply mode corresponding to meat is 6 hours, and the interval time of the power supply mode corresponding to dry goods is 48 hours. Because the interval time of the power supply mode corresponding to meat is shorter, the power supply mode corresponding to meat is adopted as the final power supply mode.

[0088] In one example, it is obtained that there are two types of food ingredients in the storage room, namely meat, dry goods and vegetables, then three power supply modes are obtained, the interval time of the power supply mode corresponding to meat is 6 hours, the interval time of the power supply mode corresponding to dry goods is 48 hours, and the interval time of the power supply mode corresponding to vegetables is 12 hours. Because the interval time of the power supply mode corresponding to meat is shorter, the power supply mode corresponding to meat is adopted as the final power supply mode used.

[0089] Step S504, determining whether the power-off time reaches a preset threshold.

[0090] Step S505: if the power-off time reaches a preset threshold, the power storage module is controlled to supply power to the electromagnetic coil according to the power supply mode.

[0091] In the scheme of this embodiment, by obtaining the type of food in the storage compartment, the power supply mode of the power storage module is determined according to the type of food and the pre-configured correspondence, so that the power storage module can adopt different power supply modes according to the type of food, thereby making the power supply mode of the power storage module adapt to the type of food, achieving the best sterilization effect for various types of food, ensuring the optimal storage time for different types of food, and facilitating the reasonable use of the power of the power storage module according to different types of food.

[0092] In addition, by selecting the power supply mode that has the shortest interval between the first two power supplies to the battery module from all the acquired power supply modes as the final power supply mode used, it is beneficial to ensure the sterilization frequency of the food types with the highest sterilization requirements when there are multiple types of food in the storage room, thereby ensuring the freshness of the food.

[0093] It should be noted that the power supply time of each power supply of the power supply modes corresponding to different types of food may be the same or different. In addition, the power supply modes corresponding to different types of food may also be different in power supply time each time but the same interval. In this case, the power supply mode of the power storage module may be determined according to the type of food and the corresponding relationship, or the power supply mode that makes the power storage module supply the longest power supply time each time may be selected as the power supply mode finally used.

[0094] In addition, it should be noted that the power supply mode corresponding to different types of food may also be intermittent power supply with a continuously changing power supply time or interval time. At this time, if the interval time is compared, the interval time between the first two power supplies is compared, and if the power supply time is compared, the first power supply time is compared.

[0095] In addition, preferably, the power storage module is configured to make the electromagnetic coil generate an alternating magnetic field or a pulsed magnetic field. Specifically, making the electromagnetic coil generate an alternating magnetic field means making the electromagnetic coil generate a magnetic field whose magnitude and direction change periodically, and making the electromagnetic coil generate a pulsed magnetic field means making the electromagnetic coil generate a magnetic field whose magnitude changes periodically but whose direction remains unchanged. The changing magnetic field can improve the sterilization effect, thereby further extending the preservation time.

[0096] like Figure 8 As shown, in one embodiment, the refrigerator control method further includes:

[0097] Step S801, obtaining the power of the power storage module. Specifically, when the refrigerator is powered on, obtaining the power of the power storage module.

[0098] Step S802, determining whether the power level is less than or equal to a preset power level threshold. Specifically, the preset power level threshold can be set or modified as needed, for example, it can be 70%, 80%, etc.

[0099] Step S803, if the power level is less than or equal to the preset power threshold, the storage module is charged until it is fully charged. For example, the preset power threshold is 80%, and when it is detected that the power level of the storage module reaches 80%, the storage module starts to be charged.

[0100] In the solution of this embodiment, by obtaining the power of the power storage module while the refrigerator is powered on, and charging the power storage module when the power of the power storage module is less than or equal to a preset power threshold, it is helpful to ensure that the power storage module has sufficient power.

[0101] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
