[0029] Figure 1 is a schematic block diagram of a refrigerator 10 according to an embodiment of the present application. The refrigerator 10 can generally include a processor 410 and a memory 420. The processor 410 and the memory 420 can be integrated on a control device of the refrigerator 10.

[0030] The memory 420 stores therein a machine executable program 421, which, when executed by the processor 410, is used to implement the control method of the refrigerator 10 of any one of the embodiments below. The processor 410 can be a central processing unit (CPU), or a digital processing unit (DSP), etc. The memory 420 is used to store the program executed by the processor 410. The memory 420 can be any medium capable of carrying or storing desired program codes in the form of instructions or data structures and capable of being accessed by the computer, but is not limited thereto. The memory 420 can also be a combination of various memories. Since the machine executable program 421, when executed by the processor 410, implements the respective processes of the method embodiments described below and achieves the same technical effects, for the sake of brevity, no further elaboration is made here.

[0031] Figure 2 is a schematic structural view of the refrigerator 10 according to one embodiment of the present application. The refrigerator 10 of the present embodiment can further include a cabinet 110 and a microorganism treatment device 200.

[0032] The cabinet 110 has one or more storage spaces 112 formed inside, for storing articles such as foodstuffs, etc. The ripening process can be optionally performed in any of the storage spaces 112, so that the storage space 112 serves as a ripening space of the refrigerator 10. That is, the ripening space of the refrigerator 10 can be any of the storage spaces 112.

[0033] The microorganism treatment device 200 is used to perform sterilization treatment on the microorganisms such as bacteria, fungi and viruses in the ripening space after the refrigerator 10 is started. Sterilization refers to sterilization treatment on the microorganisms such as bacteria, fungi and viruses. The microorganism treatment device 200 can be a sterilization device, for providing ozone and / or negative ions to the ripening space. For example, the microorganism treatment device 200 can be arranged in the ripening space. Of course, in other alternative embodiments, the microorganism treatment device 200 can also be arranged outside the ripening space, as long as the ozone and / or negative ions provided by the microorganism treatment device 200 can enter the ripening space.

[0034] In some alternative embodiments, the cabinet 110 further has an air supply duct formed therein for circulating refrigeration air, which communicates with the ripening space through an air supply port, to provide refrigeration air to the ripening space, so as to adjust the temperature and / or humidity of the ripening space.

[0035] Figure 3is an internal structure diagram of the refrigerator 10 according to an embodiment of the present application, which is an exploded view of a partial structure of the refrigerator 10. For example, the cabinet 110 can include an inner container 111, in which a storage compartment can be defined, and in which a storage container 130 can be disposed, and a maturation space can be formed in the storage container 130. An air supply port can be disposed on a duct cover 140 at a rear side of the storage compartment, and an air inlet can be formed on the storage container 130, which communicates with the air supply port. The microorganism treatment device 200 can be disposed downstream of the air supply port, upstream or downstream of the air inlet, or directly at the air inlet. For example, the refrigerator 10 can further include a fan for causing a refrigeration airflow from the air supply port to flow into the air inlet and to flow through the microorganism treatment device 200 and the maturation space.

[0036] In some embodiments, the interior of the storage container 130 further defines a maturation air duct that surrounds and communicates with the maturation space, and the microorganism treatment device 200 can be disposed in the maturation air duct.

[0037] In other embodiments, the air inlet of the storage container 130 forms an air inlet end of the maturation air duct, and the air supply port is opposite the air inlet, and the microorganism treatment device 200 can be disposed in a space (or a recess) between the air supply port and the air inlet.

[0038] Figure 4 is a schematic diagram of a control method of the refrigerator 10 according to an embodiment of the present application. The control method can generally include the following steps:

[0039] Step S402, a sterilization mode for a maturation space of the refrigerator 10 is acquired. The sterilization mode can be pre-set with a plurality of modes, and each sterilization mode is provided with corresponding sterilization parameters, such as a sterilization particle type, a sterilization particle concentration, and / or a sterilization time length, etc. Acquiring the sterilization mode for the maturation space means determining a sterilization mode suitable for the maturation space.

[0040] Step S404, sterilization is started according to the sterilization mode. That is, sterilization is started according to the sterilization parameters corresponding to the determined sterilization mode. That is, the microorganism treatment device 200 is controlled to operate according to the sterilization parameters corresponding to the determined sterilization mode.

[0041] Using the above method, by acquiring the sterilization mode for the maturation space and starting sterilization according to the sterilization mode, the sterilization process of the maturation space can be carried out under a suitable sterilization mode, so that the refrigerator 10 can effectively sterilize the maturation space, and avoid affecting the quality of the matured product due to microbial pollution during the maturation process.

[0042] The inventor realizes that the type or state of the ripening objects stored in the ripening space can vary randomly, and different types of ripening objects or different states of the same type of ripening objects can face different potential microbial contamination risks, for example, some food materials can be susceptible to contamination by type-A microorganisms, and other food materials can be susceptible to contamination by type-B microorganisms, for example, a certain food material can be susceptible to contamination by type-C microorganisms in the early stage of ripening, and can be susceptible to contamination by type-D microorganisms in the middle stage of ripening. In view of this situation, in particular, the present application provides a sterilization method specially applicable to the ripening space, which can effectively sterilize the ripening space according to the sterilization needs of the ripening space, so as to ensure the quality of the ripening objects and avoid unnecessary energy consumption, and is conducive to promoting the popularization and application of ripening technology in the field of refrigerators 10.

[0043] In some optional embodiments, before the step of obtaining the sterilization mode for the ripening space of the refrigerator 10, the control method further comprises: determining that the ripening space starts ripening. That is, in the case where it is determined that the ripening space has entered the ripening mode or is starting the ripening mode, the step of obtaining the sterilization mode for the ripening space of the refrigerator 10 is performed.

[0044] In some optional embodiments, the step of obtaining the sterilization mode for the ripening space of the refrigerator 10 comprises: determining ripening stage information, the ripening stage information being used to indicate the current ripening stage of the ripening objects in the ripening space, and determining the sterilization mode for the ripening space according to the ripening stage information.

[0045] For example, in the step of determining the sterilization mode for the ripening space according to the ripening stage information, the contamination risk level of the ripening objects and the types of microorganisms that can be contaminated can be determined according to the current ripening stage of the ripening objects. The higher the contamination risk level, the higher the sterilization intensity required by the ripening objects in this ripening stage, and the higher the sterilization particle concentration that the microbial treatment device 200 should provide. According to the types of microorganisms that the ripening objects can be contaminated in the current ripening stage, it can be determined what kind of sterilization particles the microbial treatment device 200 should provide.

[0046] By determining the ripening stage information used to indicate the current ripening stage of the ripening objects, and determining the sterilization mode for the ripening space according to the ripening stage information, each ripening stage of the ripening process can be effectively inhibited respectively, so that the refrigerator 10 can accurately sterilize for ripening and inhibit for the whole cycle of ripening.

[0047] In other optional embodiments, the step of obtaining the sterilization mode for the ripening space of the refrigerator 10 can be changed, for example, to include: determining the type information of the ripening objects in the ripening space, and determining the sterilization mode for the ripening space according to the type information of the ripening objects.

[0048] For example, when the material to be matured in the maturation space is beef, the microorganism treatment device 200 can be prompted to simultaneously provide ozone and negative ions to the maturation space at a preset ratio, and when the material to be matured in the maturation space is tuna, the microorganism treatment device 200 can be prompted to simultaneously provide ozone and negative ions to the maturation space at another preset ratio.

[0049] In some optional embodiments, the step of determining the maturation stage information comprises: obtaining a maturation duration of the maturation space, and determining the maturation stage information according to the maturation duration. The maturation duration of the maturation space refers to the processing duration experienced by the material to be matured in the maturation space after the material to be matured starts to mature.

[0050] Since the maturation duration can reflect the maturation stage currently experienced by the material to be matured, and the maturation duration is easy to detect, the maturation stage information is determined according to the maturation duration, so that the method is simple and has high accuracy.

[0051] Of course, other ways can also be used to determine the maturation stage information. For example, image information of the material to be matured can be obtained, and the maturation stage currently experienced by the material to be matured can be determined according to the obtained image information, but the present application is not limited thereto.

[0052] In some optional embodiments, the step of determining the maturation stage information according to the maturation duration can comprise: obtaining maturation cycle information of the material to be matured in the maturation space, the maturation cycle information specifying each maturation stage of the material to be matured and a corresponding stage duration range, and determining the maturation stage corresponding to the stage duration range in which the maturation duration is located as the maturation stage currently experienced by the material to be matured.

[0053] That is, the maturation cycle information can refer to the mapping relationship between each maturation stage of the material to be matured and the corresponding stage duration range. The stage duration range corresponding to the maturation stage refers to the length of time required to experience the maturation stage, and can be defined by the time range between the start time point and the end time point of the maturation stage. For example, for beef, the maturation stages can include an initial stage, an intermediate stage, and a later stage, and the maturation cycle information can specify the start time point and the end time point of the initial stage, the start time point and the end time point of the intermediate stage, and the start time point and the end time point of the later stage.

[0054] As for the division boundaries of the initial stage, the intermediate stage, and the later stage, the water content or other parameters of the material to be matured can be used to determine the division boundaries. For example, the water content of the material to be matured in the initial stage can be higher than a preset water content value, and the water content of the material to be matured in the later stage can be lower than another preset water content value. For another example, the total processing duration required for the material to be matured from the start of maturation to the completion of maturation can be equally divided to determine the division boundaries of the initial stage, the intermediate stage, and the later stage.

[0055] In some optional embodiments, the step of acquiring the aging period information of the aging object in the aging space comprises: acquiring the category information of the aging object in the aging space, and determining the aging period information of the aging object according to the category information of the aging object. The category information of the aging object can be input by the user through the man-machine interface of the refrigerator 10. Alternatively, the category information of the aging object can be collected by the image collection device of the refrigerator 10. By analyzing the image information of the aging object taken by the image collection device, the category of the aging object can be determined.

[0056] The category of the aging object in the aging space can be various. Each aging object can be pre-set with respective aging period information. By using the above method, the category information of the aging object is acquired, and the aging period information of the aging object is determined according to the category information. The current aging stage of the aging object is determined according to the matching result between the aging time length and the aging period information, and the sterilization mode is determined according to the current aging stage of the aging object, so that the refrigerator 10 can flexibly sterilize based on the category and the current aging stage of the aging object, which is beneficial to improve the intelligent degree of the refrigerator 10.

[0057] In some optional embodiments, in the step of determining the sterilization mode for the aging space according to the aging stage information, each aging stage of the aging object comprises an initial stage, an intermediate stage and a late stage, and each aging stage is correspondingly provided with an applicable sterilization mode; the sterilization mode comprises a first-level mode, a second-level mode and a third-level mode with increasing sterilization intensity.

[0058] For example, the initial stage can correspond to the first-level mode, the intermediate stage can correspond to the second-level mode, and the late stage can correspond to the third-level mode. Alternatively, the initial stage can correspond to the third-level mode, the intermediate stage can correspond to the second-level mode, and the late stage can correspond to the first-level mode. For another example, the initial stage can correspond to the second-level mode, the intermediate stage can correspond to the first-level mode, and the late stage can correspond to the third-level mode.

[0059] By combining each aging stage with each sterilization mode, a plurality of different sterilization methods can be generated, so that the refrigerator 10 can meet the sterilization needs of a plurality of different aging objects in the aging process.

[0060] The sterilization intensity of the sterilization mode is determined according to the concentration of the sterilization particles and / or the running time length (i.e. the sterilization time length) of the microorganism treatment device 200. The sterilization intensity increases with the increase of the concentration of the sterilization particles, and increases with the increase of the running time length of the microorganism treatment device 200.

[0061] For example, in the first level mode, the microorganism treatment device 200 is operated for 0.5-3 minutes, then stopped for 5-10 minutes, then operated for 0.5-3 minutes, then stopped for 5-10 minutes, and so on, so that the ozone concentration in the aging space is less than 0.01 ppm, and the negative ion concentration is 0-0.05 ppm. In the second level mode, the microorganism treatment device 200 is operated for 5-6 minutes, then stopped for 5-10 minutes, then operated for 5-6 minutes, then stopped for 5-10 minutes, and so on, so that the ozone concentration in the aging space is 0.03-0.05 ppm, and the negative ion concentration is 0-0.05 ppm. Alternatively, in the second level mode, the microorganism treatment device 200 is operated for 7-9 minutes, then stopped for 5-10 minutes, then operated for 7-9 minutes, then stopped for 5-10 minutes, and so on, so that the ozone concentration in the aging space is 0.05-0.07 ppm, and the negative ion concentration is 0-0.05 ppm. In the third level mode, the microorganism treatment device 200 is operated for 10-12 minutes, then stopped for 5 minutes, then operated for 10-12 minutes, then stopped for 5 minutes, and so on, so that the ozone concentration in the aging space is 0.07-0.09 ppm, and the negative ion concentration is 0.05 ppm.

[0062] In some optional embodiments, the step of determining the sterilization mode for the aging space according to the aging stage information comprises: determining whether the aging stage in which the aged object is currently located is the initial stage, if yes, determining the sterilization mode as the third level mode, if not, determining whether the aging stage in which the aged object is currently located is the middle stage, if the aging stage is the middle stage, determining the sterilization mode as the second level mode, if the aging stage is not the middle stage, determining whether the aging stage in which the aged object is currently located is the later stage, if the aging stage is the later stage, determining the sterilization mode as the first level mode.

[0063] That is, when the aged object is currently in the initial stage, the third level mode with higher sterilization intensity is selected to start sterilization, when the aged object is currently in the middle stage, the second level mode with moderate sterilization intensity is selected to start sterilization, and when the aged object is currently in the later stage, the first level mode with lower sterilization intensity is selected to start sterilization.

[0064] Using the above method, the concentration of sterilization particles generated by the microbial treatment device 200 is relatively high in the early stage of maturation, which can effectively kill the spoilage dominant bacteria carried on the surface of the maturing object. In the middle stage of maturation, the microorganisms mainly come from the external air received by the maturation space, or there may be a small amount of spoilage bacteria that have not been completely killed in the early stage. At this time, the secondary mode with moderate sterilization intensity is used to start sterilization, which can meet the sterilization needs of the middle stage and avoid energy waste or excessive residual sterilization particles due to too high sterilization intensity. In the later stage of maturation, the moisture content of the maturing object is already very low, and it is not easy to be contaminated by microorganisms. At this time, the primary mode with lower sterilization intensity is used to start sterilization, which can maintain a good clean state of the maturation space, save energy and effectively inhibit bacteria. This sterilization method is especially suitable for the maturation of meat food materials.

[0065] The degradation products of the ozone generated by the microbial treatment device 200 are, for example, hydroxyl ions (OH - ), oxygen ions with negative 2 valence (O 2- ), and hydrogen peroxide ions with negative 3 valence (HO 3- ). The bacteriostatic mechanism of this ozone is mainly to kill microorganisms by destroying the outer capsule membrane of bacteria, entering the interior of the microorganism to destroy its cell nucleus or deoxyribonucleotide, alkaline cell wall, cell membrane, mitochondria, and acidic nucleus. The sterilization effect depends on the concentration and action time of ozone. For example, in the tertiary mode, the ozone concentration and action time generated by the microbial treatment device 200 can effectively inactivate 5.0 lg cfu / g and above of spoilage dominant bacteria (such as Pseudomonas, Thermoactinomyces and Enterobacter, etc.), in the secondary mode, the ozone concentration and action time generated by the microbial treatment device 200 can effectively inactivate 3.0-4.0 lg cfu / g of spoilage dominant bacteria (such as Pseudomonas, Thermoactinomyces and Enterobacter, etc.), and in the primary mode, the ozone concentration and action time generated by the microbial treatment device 200 can effectively inactivate 3.0 lg cfu / g and below of spoilage dominant bacteria (such as Pseudomonas, Thermoactinomyces and Enterobacter, etc.), and there is no residual in the storage space 112, which is safe.

[0066] The negative ions generated by the microbial treatment device 200 mainly function to purify the air circulating into the storage space 112, such as eliminating microbial spores in the air, adsorbing particulate matter, decomposing odor substances and VOCs.

[0067] Using the above method, the sterilization rate in the aging space can reach more than 99%. The sterilization rate on the surface of the aged object can reach more than 90%. The sterilization method makes it possible for meat food materials to be aged for a long time (such as more than 40 days) without spoilage. Because the ozone concentration used in each sterilization mode is low, the sterilization process does not produce additional odors, and the sterilization effect of the aging space and the aged object is ensured without affecting the aging flavor volatiles of the aged object, which is convenient for users to observe and smell.

[0068] In some optional embodiments, after the step of starting sterilization according to the sterilization mode, the control method can further include: detecting the bacteria content of the air supply flow of the aging space, and adjusting the sterilization mode according to the bacteria content of the air supply flow. The bacteria content of the air supply flow refers to the content of microorganisms carried by the air supply flow, which can be characterized by concentration. For example, the refrigerator 10 can use a microorganism sensor to detect the content of microorganisms carried by the air supply flow. When the bacteria content of the air supply flow is higher than the preset bacteria threshold, it indicates that the air supply flow will introduce too many microorganisms into the aging space, causing the aged object to be contaminated. At this time, the sterilization intensity of the sterilization mode can be increased, for example, it can be increased by one to two or the like, so as to ensure the quality of the aged object.

[0069] Figure 5 is a control flowchart of the refrigerator 10 according to an embodiment of the present application. The control flowchart can generally include the following steps:

[0070] Step S502, determine that the aging space starts aging.

[0071] Step S504, obtain the aging time length of the aging space.

[0072] Step S506, obtain the category information of the aged object in the aging space.

[0073] Step S508, determine the aging period information of the aged object according to the category information of the aged object. The aging period information specifies each aging stage of the aged object and the corresponding stage time length range.

[0074] Step S510, determine the aging stage corresponding to the stage time length range in which the aging time length is located as the current aging stage of the aged object.

[0075] Step S512, determine whether the current aging stage of the aged object is the initial stage, if yes, execute step S514, if not, execute step S516.

[0076] Step S514, determine that the sterilization mode is the third mode.

[0077] Step S516, it is judged whether the current aging stage of the aging object is the middle stage. If yes, step S518 is executed. If no, step S520 is executed.

[0078] Step S518, the sterilization mode is determined as the secondary mode.

[0079] Step S520, the current aging stage of the aging object is determined as the late stage.

[0080] Step S522, the sterilization mode is determined as the primary mode.

[0081] Step S524, the sterilization is started according to the sterilization mode.

[0082] Using the above method, the sterilization process of the aging space can be carried out under the appropriate sterilization mode. The refrigerator 10 can effectively sterilize the aging space, avoiding the influence of the quality of the aging object due to the pollution of microorganisms during the aging process. Moreover, each aging stage of the aging process can be effectively inhibited, so that the refrigerator 10 can accurately sterilize the aging and inhibit the aging for the whole cycle.

[0083] At this point, those skilled in the art should realize that although the present application has been fully shown and described herein, many other variations or modifications in accordance with the principles of the present application can be directly determined or deduced from the disclosure of the present application without departing from the spirit and scope of the present application.
