[0002] The storage temperature of frozen food in a conventional refrigerator is only lower than -18℃, and the meat and other food taken out needs to be thawed before being easily cut and processed. Thawing requires a long time, and many nutrients are lost during the thawing process. Nowadays, people have higher and higher requirements for the storage quality and processing of frozen food, both long-term storage and easy cutting and processing when taken out for cooking. Under normal circumstances, meat frozen food can be stored in a soft freezing room at -7℃ for 1-2 weeks, which can ensure the quality of food and easy cutting and processing when the food is taken out for cooking. However, it is difficult to ensure the quality of frozen meat for a longer period of time.

Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0077] In order to solve the technical problem of how to improve the shelf life of food stored in the soft freezing chamber in the prior art, the present application provides a temperature control method, which can improve the shelf life of food stored in the soft freezing chamber.

[0078] Figure 1 A flowchart of a temperature control method provided by an embodiment of the present application is shown. The method can be applied to one or more electronic devices such as a refrigerator, a freezer, a smart phone, a notebook computer, a desktop computer, a portable computer, a server, etc. In addition, the execution subject of the method can be hardware or software. When the execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute the method, or multiple electronic devices can cooperate with each other to execute the method. When the execution subject is software, the method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made herein.

[0079] As shown in the method, the method specifically includes: Figure 1

[0080] Step 101: obtaining a current time.

[0081] In the embodiment, the execution subject can obtain the current time from the local or remotely.

[0082] Step 102: determining whether the current time belongs to a preset time range, wherein the opening frequency of the soft freezing chamber in the preset time range is less than or equal to a preset number threshold.

[0083] In the embodiment, the preset time range can be a time range set by the user, or a time range determined by counting the opening frequency of the soft freezing chamber in the historical time period. In addition, the preset time range can include one or more time periods.

[0084] ​The preset number threshold can be 0, 3, 5, etc.

[0085] As an example, the preset time range can be determined in the following manner:

[0086] First, the time when the door of the refrigeration equipment (including a soft freezing chamber, such as a refrigerator) or the soft freezing chamber is opened for the first time and the time when the door is opened for the last time in a day are counted.

[0087] Then, the time range corresponding to the time when the door is opened for the first time to the time when the door is opened for the last time is determined as the target range.

[0088] Then, the time period other than the target range in a day is determined as the preset time range.

[0089] As another example, the preset time range can also be determined in the following manner:

[0090] First, the time period when the door of the refrigeration equipment (including a soft freezing chamber, such as a refrigerator) or the soft freezing chamber is opened is counted in a day.

[0091] Then, for each time period, the time range corresponding to the time when the door of the soft freezing chamber is opened for the first time to the time when the door is opened for the last time in the time period is determined as the time range corresponding to the time period.

[0092] Finally, the set of time periods other than the determined time ranges in a day is determined as the preset time range.

[0093] As another example, the preset time range can also be determined in the following manner:

[0094] First, the time period when the door of the refrigeration equipment (including a soft freezing chamber, such as a refrigerator) or the soft freezing chamber is opened is counted in a day.

[0095] Then, for each time period, a first time is determined as a preset time period (such as 30 minutes) before the time when the door of the soft freezing chamber is opened for the first time in the time period, and a second time is determined as the preset time period after the time when the door is opened for the last time, and the time range corresponding to the first time to the second time is determined as the time range corresponding to the time period.

[0096] Finally, the set of time periods other than the determined time ranges in a day is determined as the preset time range.

[0097] Specifically, if the current time is 3:00 a.m. and the preset time range is from 6:00 a.m. to 8:00 p.m., the current time does not belong to the preset time range; if the current time is 12:00 noon and the preset time range is from 6:00 a.m. to 8:00 p.m., the current time belongs to the preset time range.

[0098] In step 103, in a case where the current time belongs to the preset time range, the indoor temperature of the soft-freezing chamber is controlled to decrease to a target temperature range, wherein the highest temperature included in the target temperature range is lower than the lowest temperature of the soft-freezing temperature range.

[0099] In the embodiment, for example, the target temperature range can be a temperature range of -9℃ to -15℃, and the soft-freezing temperature range can be a temperature range of -3℃ to -7℃. The highest temperature -9℃ included in the target temperature range is lower than the lowest temperature -7℃ of the soft-freezing temperature range.

[0100] In some optional implementations of the embodiment, the following steps can also be performed:

[0101] First, a temperature fluctuation value of the indoor temperature in a target time period is determined. The length of the target time period is less than a preset length threshold. The temperature fluctuation value represents a temperature difference between the highest temperature and the lowest temperature of the indoor temperature in the target time period.

[0102] Then, in a case where the temperature fluctuation value is greater than or equal to a preset threshold, the soft-freezing chamber is controlled to enter an over-cooling phase.

[0103] It can be understood that, in a case where the temperature fluctuation value of the indoor temperature in the target time period is greater than or equal to the preset threshold, it is generally considered that the user opens the door of the soft-freezing chamber to put in food at this time, and therefore, in the above optional implementation, the soft-freezing chamber can be controlled to enter the over-cooling phase in this case, so as to make the food put into the soft-freezing chamber enter an over-cooling state and keep a low-temperature state without freezing.

[0104] In some optional implementations of the embodiment, the following steps can also be performed:

[0105] First, it is determined whether the indoor temperature is greater than or equal to a preset temperature threshold.

[0106] The preset temperature threshold is higher than the highest temperature of the soft-freezing temperature range.

[0107] For example, in a case where the soft-freezing temperature range is -3℃ to -7℃, the preset temperature threshold can be 2℃, 5℃, etc.

[0108] Afterwards, in a case that the indoor temperature of the soft-freezing chamber is greater than or equal to the preset temperature threshold, the soft-freezing chamber is controlled to enter a supercooling phase.

[0109] In the supercooling phase, the object (for example, meat) placed in the soft-freezing chamber can be in a supercooling state.

[0110] It can be understood that, in a case that the indoor temperature of the soft-freezing chamber is high (i.e., the indoor temperature is greater than or equal to the preset temperature threshold), it can be generally considered that the user opens the door of the soft-freezing chamber to place food at this time. Therefore, in the optional implementation manner, the soft-freezing chamber can be controlled to enter the supercooling phase in a case that the indoor temperature of the soft-freezing chamber is high, so that the food placed in the soft-freezing chamber is in a supercooling state, and the low-temperature state of the food is maintained without freezing.

[0111] In some application scenarios of the optional implementation manner, the step 103 can be performed in the following manner:

[0112] In a case that the indoor temperature of the soft-freezing chamber is less than the preset temperature threshold and the current time belongs to the preset time range, the indoor temperature of the soft-freezing chamber is controlled to be reduced to a target temperature range.

[0113] It can be understood that, in a case that the indoor temperature of the soft-freezing chamber is high (i.e., the indoor temperature is greater than or equal to the preset temperature threshold), it can be generally considered that the time at which the user opens the door of the soft-freezing chamber to place food is relatively close, and the probability that the user opens the door of the soft-freezing chamber again to take or place food is high. At this time, the indoor temperature of the soft-freezing chamber can not be controlled to be reduced to the target temperature range. In a case that the indoor temperature of the soft-freezing chamber is less than the preset temperature threshold and the current time belongs to the preset time range, the indoor temperature of the soft-freezing chamber is controlled to be reduced to the target temperature range, which can to some extent avoid a case that the user cannot easily process (for example, cut, thaw, etc.) the food taken out.

[0114] The temperature control method provided by the embodiment of the present application can acquire a current time, and then determine whether the current time belongs to a preset time range. In the preset time range, the opening frequency of the soft-freezing chamber is less than or equal to a preset number threshold. Then, in a case that the current time belongs to the preset time range, the indoor temperature of the soft-freezing chamber is controlled to be reduced to a target temperature range. The highest temperature included in the target temperature range is lower than the lowest temperature of the soft-freezing temperature range. In this way, the temperature of the soft-freezing chamber can be controlled to be lower than the soft-freezing temperature range in a time range in which the opening frequency of the soft-freezing chamber is low, so that the shelf life of the food in the soft-freezing chamber is improved.

[0115] Figure 2A flowchart of another temperature control method provided by the embodiments of the present application is shown in FIG. 2.

[0116] As shown in FIG. 2, the method specifically includes the following steps. Figure 2

[0117] Step 201: Acquire a current time.

[0118] In this embodiment, step 201 is basically the same as step 101 in the corresponding embodiment, and thus will not be repeated here. Figure 1 Step 202: Determine whether the current time belongs to a preset time range, wherein, within the preset time range, the opening frequency of the soft-freezing chamber is less than or equal to a preset number threshold.

[0119] In this embodiment, step 202 is basically the same as step 102 in the corresponding embodiment, and thus will not be repeated here.

[0120] Figure 1 Step 203: In the case where the current time belongs to the preset time range, control the indoor temperature of the soft-freezing chamber to decrease to a target temperature range, wherein the highest temperature included in the target temperature range is lower than the lowest temperature of the soft-freezing temperature range.

[0121] In this embodiment, step 203 is basically the same as step 103 in the corresponding embodiment, and thus will not be repeated here.

[0122] Step 204: Determine whether the current time reaches a target time, wherein the target time belongs to the preset time range. Figure 1 In this embodiment, whether the current time reaches the target time can be determined in units of days.

[0123] Specifically, in a day, if the current time is before the target time, the current time does not reach the target time; if the current time is after the target time or the current time is the target time, the current time has reached the target time. For example, if the current time is 4:01 am and the target time is 4:00 am, the current time has reached the target time; if the current time is 3:00 am and the target time is 4:00 am, the current time has not reached the target time.

[0124] Illustratively, the target time can be determined based on the length of time between the start time and the end time of the preset time range. Alternatively, the target time can be determined based on the length of time of the last time period included in the preset time range.

[0125]

[0126]

[0127] ​​​​For example, if the preset time range is from 8pm to 6am, the target time can be 4am.

[0128] In some cases, the length of time between the target time and the end time of the preset time range is negatively correlated with the temperature of the room in which the soft-freezing chamber is located.

[0129] Step 205, in the case where the current time reaches the target time, the indoor temperature of the soft-freezing chamber is controlled to increase to the soft-freezing temperature range.

[0130] In this embodiment, in the case where the current time reaches the target time, the indoor temperature of the soft-freezing chamber (which is usually within the target temperature range, for example, -9℃ to -15℃) can be controlled to increase to the soft-freezing temperature range (for example, -3℃ to -7℃).

[0131] In some optional implementations of this embodiment, the indoor temperature of the soft-freezing chamber can be controlled to increase to the soft-freezing temperature range in the following manner:

[0132] First, the indoor temperature of the soft-freezing chamber is controlled to increase.

[0133] For example, the indoor temperature of the soft-freezing chamber can be controlled to increase by stopping refrigeration or heating the soft-freezing chamber.

[0134] Then, during the process of increasing the indoor temperature, the temperature increase rate of the indoor temperature is determined.

[0135] In this process, the temperature difference between two time points during the process of increasing the indoor temperature and the length of time between the two time points can be calculated first. Then, the quotient of the temperature difference and the length of time is determined as the temperature increase rate of the indoor temperature.

[0136] Then, it is determined whether the temperature increase rate is less than or equal to a preset speed threshold.

[0137] Finally, in the case where the temperature increase rate is less than or equal to the preset speed threshold, the temperature increasing device of the soft-freezing chamber is controlled to start to accelerate the increase of the indoor temperature to the soft-freezing temperature range.

[0138] It can be understood that in the above optional implementation, in the case where the indoor temperature of the soft-freezing chamber increases at a slow rate, the temperature increasing device can be started to accelerate the increase of the indoor temperature of the soft-freezing chamber to shorten the time for increasing to the soft-freezing temperature range.

[0139] In some application scenarios of the above optional implementation, the enabling condition of the temperature raising device includes that the indoor temperature belongs to the target temperature range. The disabling condition of the temperature raising device includes that the indoor temperature does not belong to the target temperature range. For example, the disabling condition of the temperature raising device can include that the indoor temperature belongs to the soft cooling temperature range.

[0140] It can be understood that in the above application scenarios, the temperature raising device is only enabled when the indoor temperature belongs to the target temperature range, so that the temperature raising device can be used only to control the indoor temperature in the target temperature range, avoiding the false enabling of the temperature raising device.

[0141] In some optional implementations of the present embodiment, the indoor temperature of the soft freezing chamber can be controlled to rise to the soft freezing temperature range in the following manner:

[0142] The indoor temperature of the soft freezing chamber is controlled to rise to the soft freezing temperature range before or at the starting time of the preset time range.

[0143] It can be understood that in the above optional implementation, the indoor temperature of the soft freezing chamber can be controlled to rise to the soft freezing temperature range before or at the starting time of the preset time range, so that when the user has a high probability of accessing the food in the soft freezing chamber, the temperature of the food taken out by the user belongs to the soft freezing temperature range, so that the food can be easily cut and processed.

[0144] It should be noted that in addition to the above, the present embodiment can also include Figure 1 corresponding technical features described in the embodiments, thereby achieving Figure 1 the technical effects of the temperature control method, please refer to Figure 1 the related description, for brevity, will not be repeated here.

[0145] The temperature control method provided by the present embodiment can control the indoor temperature of the soft freezing chamber to rise to the soft freezing temperature range when the current time belongs to the target time in the preset time range, so that the food taken out by the user can be easily cut and processed.

[0146] Figure 3 A structural schematic diagram of a refrigeration equipment provided by the present embodiment.

[0147] Specifically, as Figure 3 shown, the refrigeration equipment 1000 includes a soft freezing chamber 100 and a control unit 200, and the soft freezing chamber 100 and the control unit 200 are electrically connected; the control unit 200 is used to implement any of the above temperature control methods.

[0148] Optionally, the refrigeration equipment 1000 can also include a freezing chamber and a refrigerating chamber, and the soft freezing chamber can be arranged in the freezing chamber or the refrigerating chamber, or can be independently arranged from the freezing chamber and the refrigerating chamber.

[0149] The refrigeration equipment can be a refrigerator, a freezer or the like.

[0150] The refrigeration equipment is taken as a refrigerator as an example for example description of the embodiments of the present application, but it should be noted that the embodiments of the present application can have the features described below, but the following description does not constitute a limitation on the protection scope of the embodiments of the present application.

[0151] The conventional refrigerator only stores frozen food below -18℃, and the meat taken out needs to be thawed before being easily cut and processed. Thawing needs a long time, and a lot of nutrients are lost in the process of thawing. Nowadays, people have higher and higher requirements for the storage quality and processing of frozen food. It is required to store for a long time and to be easily cut and processed when taken out for cooking. In a storage period of 1-2 weeks, the meat frozen food can be stored at -7℃ soft freezing storage, which can ensure the quality of the food and the easy cutting and processing when the food is taken out for cooking. However, it is difficult to ensure the quality of the meat frozen food if the storage time is longer. The refrigerator with variable freezing storage temperature provided by the method can solve the above problems. Most users cook during the day and basically do not cook at night, especially from 9 pm to 6 am the next day. Therefore, a lower storage temperature can be used in this period to prolong the storage time of the meat frozen food. In the daytime, the food is stored at a temperature in the range of -3℃ to -7℃, so that the food can be easily cut and processed when cooked during the day, and the meat frozen food can be stored at a lower temperature at night to prolong the storage time.

[0152] As shown in Figure 4 , Figure 4 Another structure diagram of a refrigeration equipment provided by the embodiments of the present application is shown. The refrigerator in the diagram is composed of a freezing chamber, a refrigerating chamber and a soft freezing chamber. The soft freezing chamber is arranged inside the refrigerating chamber (so that the temperature fluctuation of the soft freezing chamber is small), and is composed of a separate air door, a temperature sensor and an air outlet. A temperature compensation heater (i.e. the above-mentioned temperature rising device) is arranged at the bottom of the soft freezing chamber to help the meat food to be warmed before use by the user during the day. In the period when the user does not use the refrigerator at night, the soft freezing chamber is controlled at a lower soft freezing temperature to ensure that the storage time of the meat food is longer. In the daytime, the food is stored at a temperature in the range of -3℃ to -7℃, so that the meat food taken out can be easily cut and processed. As an example, refer to Figure 5 , Figure 5 A temperature control curve in a method of a refrigeration equipment provided by the embodiments of the present application is shown.

[0153] In addition, the temperature in the chamber can be detected to determine whether the food needs to enter the supercooling introduction stage again after being put in, so that the frozen food entering the freezing stage can enter the supercooling introduction stage. When new food is put in, if the temperature in the chamber rises to above 2℃, the food will go through the supercooling introduction stage again, so that the food in the freezing stage can pass through the supercooling state, and large ice crystals will not be generated when the food is frozen, so that the food can be frozen better. Therefore, the storage quality of the food can be improved, and the taste of the food can be ensured.

[0154] The following refers to Figure 6 , Figure 6 The flowchart of another temperature control method provided by the embodiment of the application is shown.

[0155] As shown in Figure 6 , when the meat food is put in the soft freezing chamber, the temperature in the chamber is sensed by the temperature sensor, and the meat food is brought into the supercooling state by using a specific cooling program. Then, the meat food is brought out of the supercooling state and into the soft freezing state for storage by using a strong cooling program (the difference between the strong cooling program and the specific cooling program is that the highest rotating speed of the compressor and the highest rotating speed of the fan are used to cool the food quickly). Generally, the temperature is controlled to be in the range of -3℃ to -7℃. When the time period (i.e., the preset time range) arrives, the control temperature is lowered, and generally, the temperature is in the range of -9℃ to -15℃, so that the meat food is brought into the lower storage temperature range, and the storage time of the meat food is prolonged. When the time (i.e., the current time) reaches 4 a.m. (i.e., the target time), the control temperature is raised, and the temperature is controlled to be in the original range of -3℃ to -7℃. When the temperature rises very slowly, the temperature compensation heater (i.e., the temperature raising device) placed at the bottom of the soft freezing chamber can be started to help the temperature of the food rise to the range of -3℃ to -7℃. In this way, when the meat food is taken out in the morning for cooking, the meat food can be easily cut and processed, and the nutrition of the meat food is not lost. During the day, the temperature is controlled to be in the range of -3℃ to -7℃, and during the night, the temperature is controlled to be in the range of -9℃ to -15℃, and the cycle is repeated.

[0156] The following refers to Figure 7 , Figure 7 The structure diagram of the temperature raising device of the refrigeration equipment provided by the embodiment of the application is shown. As shown in Figure 7 , the temperature raising device (i.e., the heater) is that the heating wire is attached to the aluminum foil, and the aluminum foil is attached to the inner wall of the refrigerator (e.g., the temperature compensation heater in the layout diagram). The temperature raising device can be heated by 220V mains. The heating mode is that the heat is radiated to the food in the chamber. The temperature of the heater is that the heater is started to heat when the temperature is in the range of -9℃ to -15℃, and the heater is stopped to heat when the temperature of the heater is in the range of -3℃ to -7℃.

[0157] When the soft freezing chamber still has the original food storage and new meat food is put in, the temperature sensor inside the chamber can sense it again, and the specific cooling program is entered to put the meat food into the supercooling state, and enter the above-mentioned cycle; when the new meat food is insufficient to cause the temperature change of the chamber, the chamber temperature control is still according to the above-mentioned cycle. That is, when the soft freezing chamber temperature sensor detects that it is greater than the supercooling introduction temperature, it starts from the supercooling introduction stage.

[0158] Therefore, when the user does not use the refrigerator at night, a lower soft freezing storage temperature is adopted, the storage time of the meat food is prolonged, and the meat food can be easily cut and processed when it is taken out during the day. The problem that the frozen food stored below-18℃ is not easy to cut and process, and a lot of nutrients are lost during thawing can be solved. The problem of short storage time of meat frozen food in a soft frozen state is solved.

[0159] It should be noted that, in addition to the above-mentioned content, the present embodiment can also include the technical features described in the above embodiments, and further realize the technical effects of the temperature control method shown above.

Therefore, the temperature of the soft freezing chamber can be controlled below the soft freezing temperature range in the time range with less opening frequency of the soft freezing chamber, so that the shelf life of the food in the soft freezing chamber is improved.
