Description

Technical Field

[0001] The present application relates to the field of refrigerators, and in particular to a control method and a refrigerator with a cold damage prevention function. Background Art

[0002] Low-temperature storage in refrigerators is widely used to preserve various fruits and vegetables, and is one of the most effective storage methods. However, inappropriate low-temperature storage conditions can lead to physiological dysfunction in fruits and eventually chilling damage. Chilling damage refers to the phenomenon that plants are at an unsuitable storage temperature above the freezing point of their tissues, causing physiological metabolic disorders. Chilling damage can cause damage to the internal structure of fruits and vegetables, loss of nutrients, and a decrease in disease resistance and storage resistance, which can lead to the deterioration and rot of fruits and vegetables.

[0003] Different types of fruits and vegetables have different abilities to tolerate low temperatures. Inappropriate low temperatures and freezing will affect the normal physiological functions of the fruit, causing changes in flavor quality or the occurrence of physiological diseases, which is not conducive to storage. Therefore, refrigerated storage of fruits and vegetables should control different storage temperatures according to different types. However, in refrigerators currently on the market, the temperature of the fruit and vegetable refrigeration area is generally controlled between 2 and 6°C, and the temperature of the fruit and vegetable refrigeration area cannot be automatically adjusted according to the type of fruits and vegetables placed in it. It is easy for some fruits and vegetables to suffer from cold damage, and the manually set cold storage temperature is too high, causing the fruits and vegetables to quickly shrivel and deteriorate. Therefore, it is particularly important to provide a refrigerator with an anti-chilling damage function to solve the problem of cold damage caused by the refrigerator's inability to automatically adjust the temperature when storing fruits and vegetables.

[0060] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0061] It should be noted that the terms "first", "second", etc. in the specification and claims of the embodiment of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the embodiment of the present application described here can be implemented in an order other than those illustrated or described here. Thus, the features defined as "first" and "second" can expressly or implicitly include one or more of the features. In the description of the present embodiment, unless otherwise specified, the meaning of "multiple" is two or more. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or server comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0062] Low temperature is very effective in maintaining the flavor quality of fresh fruits and vegetables. Storing fruits and vegetables at low temperatures is one of the ways to keep them fresh in our daily lives. In the home, the refrigerator is the most indispensable appliance in our lives. We are often used to putting the fruits we buy home in the refrigerator.

[0063] The storage temperature of the refrigerator should be appropriate. Too high a temperature will easily cause the respiration intensity of the fruit to rise, resulting in post-ripening. Too low a temperature will easily cause frost damage to the fruit. Generally speaking, the lower the temperature, the less the nutritional consumption of the product, and the longer the fresh quality can be maintained. The preservation temperature is not unlimitedly low, because when the temperature is so low that the product cannot bear it, chilling or freezing damage will occur. Therefore, fresh-keeping storage requires a relatively stable and suitable low temperature condition.

[0064] Because different types of fruits and vegetables have different tolerance to low temperatures, inappropriate low temperatures and freezing will affect the normal physiological functions of the fruit, causing changes in flavor quality or the occurrence of physiological diseases, which is not conducive to storage. Therefore, different storage temperatures should be controlled for different types of fruits and vegetables when refrigerated.

[0065] In the refrigerators currently on the market, the temperature of the fruit and vegetable cold storage area is generally controlled between 2 and 6 degrees Celsius. This is a temperature point where cold damage is very likely to occur to tropical and tropical fruits. Therefore, some tropical temperate fruits (such as mangoes, papayas, bananas, etc.) cannot be stored in ordinary refrigerators. However, if stored at room temperature, high temperatures will also accelerate the growth and reproduction of pathogens such as mold, causing the fruit to be infected with pathogens and rot and deteriorate. Therefore, refrigerators with anti-cold damage functions have become a pain point that urgently needs to be solved in the market.

[0066] On the one hand, an embodiment of the present application provides a control method for a refrigerator with a cold damage prevention function, the refrigerator including a cold damage prevention temperature variable zone, and the control method includes:

[0067] S10: When the door of the refrigerator is not operated, determining the first type of fruits and vegetables stored in the cold damage prevention temperature changing zone 1.

[0068] Exemplarily, the cold damage prevention temperature changing zone 1 of the refrigerator disclosed in the embodiment of the present application has an independent temperature control system 12 and a temperature control logic system 11, which can independently control the temperature of the temperature changing zone.

[0069] When the door of the refrigerator is not operated, that is, the door of the refrigerator is not opened, the refrigerator will determine the type of fruits and vegetables currently stored in the anti-chilling damage temperature variable zone 1, that is, determine the first type of fruits and vegetables stored in the anti-chilling damage temperature variable zone 1.

[0070] Optionally, the types of fruits and vegetables refer to specific types of fruits and vegetables stored in the refrigerator, such as apples, bananas, oranges, mangoes, spinach, eggplants, etc.

[0071] S30: In response to the door opening and closing operation signal for the refrigerator, determining the second type of fruits and vegetables in the cold damage prevention temperature changing zone 1.

[0072] Exemplarily, when the temperature control logic system 11 obtains the operation signal of opening and closing the refrigerator door, it responds to the signal and determines the second type of fruits and vegetables in the cold damage prevention temperature change zone 1 at this time.

[0073] S50: When it is determined that there is a difference between the first fruit and vegetable category and the second fruit and vegetable category, a temperature control strategy for the chilling injury prevention temperature changing zone 1 is determined according to the second fruit and vegetable category.

[0074] Exemplarily, when it is determined that there is a difference between the first type of fruits and vegetables and the second type of fruits and vegetables, that is, when it is determined that new types of fruits and vegetables are placed in the refrigerator, the anti-chilling damage temperature variable zone 1 will re-determine the temperature control strategy of the anti-chilling damage temperature variable zone 1 according to the second type of fruits and vegetables, that is, the current type of fruits and vegetables.

[0075] When the second type of fruits and vegetables is exactly the same as the first type of fruits and vegetables, the original temperature control strategy is maintained, but the target storage temperature is fine-tuned according to the current state of the second type of fruits and vegetables, and the fine-tuning range does not exceed the temperature range corresponding to the current temperature control strategy.

[0076] According to research data, most fruits and vegetables have suitable storage temperatures and clear temperature values. As shown in Tables 1 and 2, Tables 1 and 2 show the optimum storage temperature and chilling temperature for some fruits and vegetables. For fruits and vegetables that are not sensitive, they can be stored at a temperature slightly above the freezing point. For fruits and vegetables that are sensitive to chilling damage, the minimum safe storage temperature varies depending on the type. The general principle is that the storage temperature should be higher than the critical chilling temperature. Therefore, a temperature control strategy is formulated based on this principle.

[0081]

[0082] S70: Adjusting the temperature of the cold damage prevention temperature changing zone 1 based on the temperature control strategy.

[0083] Exemplarily, after the temperature control strategy is determined, the temperature of the cold damage prevention temperature changing zone 1 is adjusted according to the temperature control measurement and control.

[0084] The embodiment of the present application provides a control method for a refrigerator with a cold damage prevention function, in which a cold damage prevention temperature variable zone is set in the refrigerator for placing fruits and vegetables, and when the door of the refrigerator is not operated, a first fruit and vegetable type of fruits and vegetables stored in the cold damage prevention temperature variable zone is determined, and in response to the door opening and closing operation signal for the refrigerator, a second fruit and vegetable type in the cold damage prevention temperature variable zone is determined, and when it is determined that there is a difference between the first fruit and vegetable type and the second fruit and vegetable type, a temperature control strategy for the cold damage prevention temperature variable zone is determined according to the second fruit and vegetable type, and the temperature of the cold damage prevention temperature variable zone is adjusted based on the temperature control strategy. The refrigerator of the embodiment of the present application uses the above control method to realize intelligent recognition of whether new types of fruits and vegetables are put in, and when it is recognized that new types of fruits and vegetables are put in, a new temperature control strategy is automatically determined, and the optimal storage temperature is automatically set, which can effectively prevent the occurrence of cold damage, can take into account both freshness preservation and cold damage prevention, improve the user's sense of use, improve the intelligent level of refrigerator control, and reduce food waste.

[0085] In an alternative embodiment, Figure 2 As shown, in the above step S50, the above step determines the temperature control strategy of the anti-chilling injury temperature changing zone 1 according to the second fruit and vegetable type, including:

[0086] S51: Determine a storage type corresponding to the second type of fruits and vegetables; the storage type includes at least one of cold-sensitive fruits and vegetables and low-temperature storage fruits and vegetables.

[0087] For example, when a new type of fruit and vegetable is placed in the refrigerator, the storage type corresponding to the second type of fruit and vegetable in the current refrigerator's anti-chilling temperature change zone 1 must first be determined; the storage type includes at least one of cold-sensitive fruits and vegetables and low-temperature storage fruits and vegetables. The purpose of confirming the storage type is to better match the temperature control strategy so that the fruits and vegetables have better freshness.

[0088] Cold-sensitive fruits and vegetables refer to those that are sensitive to low temperatures. They are prone to chilling damage during low-temperature storage and cold chain transportation, such as the fruits and vegetables shown in Table 2, as well as green peppers, bananas, grapes, etc.

[0089] Low-temperature storage fruits and vegetables refer to those fruits and vegetables that can extend their shelf life under low temperature conditions, such as the fruits and vegetables shown in Table 1, as well as longan, strawberry, etc.

[0090] Optionally, the temperature control logic system 11 of the refrigerator is pre-set with information such as storage types corresponding to all types of fruits and vegetables, as well as chilling temperature, storage adaptation temperature, etc., and is updated regularly through the Internet.

[0091] S52: Determine a temperature control strategy according to the storage type corresponding to the second type of fruits and vegetables.

[0092] Exemplarily, the temperature control strategy is determined according to the storage type corresponding to the second type of fruits and vegetables. For example, when the storage type corresponding to the second type of fruits and vegetables does not include cold-sensitive fruits and vegetables, a low-temperature strategy is selected; when the storage type corresponding to the second type of fruits and vegetables includes cold-sensitive fruits and vegetables and low-temperature storage fruits and vegetables, a high-temperature strategy is selected; when the storage type corresponding to the second type of fruits and vegetables only includes cold-sensitive fruits and vegetables, a variable temperature strategy is selected.

[0093] like Figure 3 As shown, in the above step S70, the temperature of the anti-chilling damage temperature changing zone 1 is adjusted based on the temperature control strategy, including:

[0094] S71: Determine the target storage temperature according to the temperature control strategy.

[0095] For example, each type of fruit and vegetable has the most suitable storage temperature to achieve the best preservation effect. Moreover, based on scientific research results, the critical temperature points of chilling damage for various types of fruits and vegetables have also been determined. Therefore, in combination with artificial intelligence technology, images are used to automatically identify the types of fruits and vegetables in the anti-chilling damage temperature zone 1, and then the target storage temperature can be obtained based on the type information. Combined with actual user usage scenarios, long-term preservation and prevention of chilling damage are taken into account at the same time. That is, the target storage temperature is further determined according to the temperature control strategy determined in the above step S52, and the principle for determining the target storage temperature is that the storage temperature should be higher than the critical chilling damage temperature of all fruits and vegetables.

[0096] S72: Based on the target storage temperature, determine the startup temperature and shutdown temperature of the cold damage prevention temperature changing zone 1.

[0097] Exemplarily, after determining the target storage temperature, the temperature control logic system 11 calculates the startup temperature and shutdown temperature of the anti-cold damage temperature variable zone 1 according to the target storage temperature to obtain the startup temperature and shutdown temperature of the anti-cold damage temperature variable zone 1.

[0098] Optionally, the startup temperature of the cold damage prevention temperature variable zone 1 is the target storage temperature plus a preset temperature threshold, and the shutdown temperature of the cold damage prevention temperature variable zone 1 is the target storage temperature minus the preset temperature threshold. The optimal value of the preset temperature threshold is 1°C.

[0099] S73: Obtain the current temperature of the cold damage prevention temperature changing zone 1.

[0100] Exemplarily, the cold damage prevention temperature variable zone 1 also includes a temperature sensing system 13 for real-time acquisition of the temperature of the cold damage prevention temperature variable zone 1. When it is confirmed that new fruits and vegetables are put in, the current temperature of the cold damage prevention temperature variable zone 1 is acquired and transmitted to the temperature control logic system 11.

[0101] S74: Based on the current temperature, the startup temperature and the shutdown temperature, the temperature of the cold damage prevention temperature variable zone 1 is adjusted.

[0102] For example, based on the current temperature, the startup temperature and the shutdown temperature, the specific adjustment method for adjusting the temperature of the cold damage prevention temperature changing zone 1 includes but is not limited to:

[0103] When the current temperature of the anti-cold damage temperature variable zone 1 is greater than or equal to the startup temperature, the temperature control logic system 11 controls to turn on the temperature control system 12 and turns on the cooling mode. When the current temperature of the anti-cold damage temperature variable zone 1 is less than or equal to the startup temperature, the temperature control logic system 11 controls to turn off the cooling mode.

[0104] The refrigerator in the embodiment of the present application can automatically determine the temperature control strategy for the anti-chilling damage temperature variable zone, as well as the target storage temperature, startup temperature and shutdown temperature corresponding to the temperature control strategy through the above method, which can effectively prevent the occurrence of chilling damage to fruits and vegetables, and can take into account both freshness preservation and chilling damage prevention, thereby improving the user's experience of use and reducing food waste.

[0105] In an optional embodiment, in the above step S51, determining the temperature control strategy according to the storage type corresponding to the second type of fruits and vegetables includes:

[0106] S5101: When it is determined that the storage type corresponding to the second fruit and vegetable category does not include cold-sensitive fruits and vegetables, the temperature control strategy is determined to be a low temperature strategy.

[0107] Exemplarily, when it is determined that the storage type corresponding to the second type of fruits and vegetables does not include cold-sensitive fruits and vegetables, the temperature control strategy is determined to be a low temperature strategy.

[0108] Optionally, the determination of the temperature control strategy and the determination of the storage type corresponding to the second type of fruits and vegetables are performed in an independent temperature control logic system 11 of the refrigerator's cold damage prevention zone.

[0109] In the above step S71, determining the target storage temperature according to the temperature control strategy includes:

[0110] S7101: Determine, according to the low temperature strategy, that the target storage temperature is a preset low temperature, where the preset low temperature is determined based on a storage type corresponding to the second type of fruit and vegetable.

[0111] Exemplarily, the target storage temperature is determined according to the low temperature strategy to be a preset low temperature temperature corresponding to the low temperature strategy.

[0112] The preset low temperature is determined based on the specific type of fruit and vegetable, that is, the temperature control logic system 11 performs a comprehensive evaluation based on the types of all fruits and vegetables included in the second fruit and vegetable category to determine the preset low temperature.

[0113] Optionally, the preferred general range of the preset low temperature is 2-4°C.

[0114] It should be noted that 2-4°C is only a preferred range, but does not represent the full range of the preset low temperature disclosed in the embodiments of the present application. When different types of fruits and vegetables are placed in the anti-chilling injury temperature variable zone 1, the preset minimum temperature will also be different. The preset low temperature is determined based on the specific type of fruits and vegetables. In the embodiments of the present application, no more specific restrictions are imposed on the preset low temperature.

[0115] The refrigerator in the embodiment of the present application can be realized by identifying the storage type corresponding to the fruit and vegetable types in the anti-chilling damage temperature change zone and then determining the storage strategy as a low-temperature strategy, and determining the target storage temperature corresponding to the low-temperature strategy, which can effectively prevent the occurrence of chilling damage to fruits and vegetables, and can take into account both freshness preservation and chilling damage prevention, thereby improving the user's experience of use and reducing food waste.

[0116] In an optional embodiment, in the above step S51, determining the temperature control strategy according to the storage type corresponding to the second type of fruits and vegetables includes:

[0117] S5102: When it is determined that the storage type corresponding to the second fruit and vegetable category includes cold-sensitive fruits and vegetables and low-temperature storage fruits and vegetables, the temperature control strategy is determined to be a high temperature strategy.

[0118] For example, when cold-sensitive fruits and vegetables and low-temperature storage fruits and vegetables coexist in the anti-chilling temperature zone 1, they can only be stored at a higher temperature to ensure that all fruits and vegetables will not suffer from chilling damage. This temperature control strategy is a high-temperature strategy.

[0119] In the above step S71, determining the target storage temperature according to the temperature control strategy includes:

[0120] S7102: Determine the critical temperature of chilling damage for all fruits and vegetables in the chilling damage prevention temperature zone 1; and determine the target storage temperature based on the critical temperature of chilling damage according to the high temperature strategy.

[0121] Exemplarily, it is necessary to determine the critical chilling temperature of all fruits and vegetables in the chilling damage prevention temperature zone 1. According to the principle of the high temperature strategy, it is necessary to ensure that all fruits and vegetables will not be chilled. Therefore, the standard storage temperature is determined to be the lowest chilling temperature of all fruits and vegetables in the second fruit and vegetable category.

[0122] The refrigerator in the embodiment of the present application can be realized by identifying the storage type corresponding to the fruit and vegetable types in the anti-chilling damage temperature change zone and then determining the storage strategy as a high-temperature strategy, and determining the target storage temperature corresponding to the high-temperature strategy, which can effectively prevent the occurrence of chilling damage to fruits and vegetables, and can take into account both freshness preservation and chilling damage prevention, thereby improving the user's experience of use and reducing food waste.

[0123] In an optional embodiment, in the above step S51, determining the temperature control strategy according to the storage type corresponding to the second type of fruits and vegetables includes:

[0124] S5103: When it is determined that the storage type corresponding to the second fruit and vegetable category is cold-sensitive fruits and vegetables, the temperature control strategy is determined to be a variable temperature storage strategy; the variable temperature storage strategy is to store at a low temperature storage temperature for a first preset time and at a high temperature storage temperature for a second preset time.

[0125] For example, when all fruits and vegetables stored in the anti-chilling temperature variable zone 1 are cold-sensitive fruits and vegetables, the temperature control strategy is determined to be a variable temperature storage strategy; the variable temperature storage strategy is to store at a low temperature storage temperature for a first preset time and at a high temperature storage temperature for a second preset time. Specifically, the variable temperature storage strategy adopts an intermittent temperature treatment method, which can effectively reduce and delay the occurrence of chilling injury symptoms.

[0126] The mechanism of action of the variable temperature storage strategy is: through multiple short-term temperature rise treatments, the increase in cell membrane permeability and the degree of membrane paper peroxidation are inhibited, the increase in PAL\POD content is inhibited, a high soluble sugar and acid content is maintained, and a better preservation effect is obtained.

[0127] In the above step S71, determining the target storage temperature according to the temperature control strategy includes:

[0128] S7103: According to the variable temperature storage strategy, the target storage temperature is determined to be a low-temperature storage temperature and a high-temperature storage temperature; the low-temperature storage temperature and the high-temperature storage temperature are determined based on the storage type corresponding to the second fruit and vegetable category.

[0129] Exemplarily, the variable temperature storage strategy is to store at a low temperature storage temperature for a certain period of time, then increase the temperature to a high temperature storage temperature, and then store at the high temperature storage temperature for a certain period of time. Therefore, it is necessary to first determine the specific low temperature storage temperature and high temperature storage temperature according to the storage type corresponding to the second type of fruits and vegetables.

[0130] In an optional embodiment, after the above step S7103, the above method further includes:

[0131] A first preset time corresponding to the low-temperature storage temperature is determined, and a second preset time corresponding to the high-temperature storage temperature is determined; the first preset time and the second preset time are determined based on the storage type corresponding to the second fruit and vegetable type.

[0132] Exemplarily, after obtaining the low-temperature storage temperature and the high-temperature storage temperature, the first preset time corresponding to the low-temperature storage temperature is determined, and the second preset time corresponding to the high-temperature storage temperature is determined; the first preset time and the second preset time are determined based on the storage type corresponding to the second type of fruits and vegetables.

[0133] Optionally, the following is a specific embodiment of the above temperature change strategy, for example, within 24 hours a day, within 20-22 hours, the low temperature storage temperature of the anti-chilling temperature change zone 1 is 2-4°C; within 4-2 hours, the high temperature storage temperature is 12-14°C. It should be noted that this is only an exemplary embodiment, and the actual high temperature storage temperature, low temperature storage temperature, first preset time and second preset time are determined according to the second fruit and vegetable type.

[0134] In the above step S72, the start-up temperature and the shutdown temperature of the anti-cold damage temperature changing zone 1 are determined based on the target storage temperature, including:

[0135] A low-temperature storage startup temperature and a low-temperature storage shutdown temperature are obtained based on the low-temperature storage temperature, and a high-temperature storage startup temperature and a high-temperature storage shutdown temperature are obtained based on the high-temperature storage temperature.

[0136] Exemplarily, when the target storage temperature includes a high temperature storage temperature and a low temperature storage temperature, the low temperature storage startup temperature and the low temperature storage shutdown temperature are obtained based on the low temperature storage temperature, and the high temperature storage startup temperature and the high temperature storage shutdown temperature are obtained based on the high temperature storage temperature.

[0137] The refrigerator in the embodiment of the present application can be realized by identifying the storage type corresponding to the fruit and vegetable types in the anti-chilling damage variable temperature zone and then determining the storage strategy as the variable temperature strategy, as well as determining the target storage temperature, startup temperature and shutdown temperature corresponding to the variable temperature strategy. This can effectively prevent the occurrence of chilling damage to fruits and vegetables, and can take into account both freshness preservation and chilling damage prevention, thereby improving the user's experience of use and reducing food waste.
