Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0053] The present application provides a control method for a refrigerator, wherein the refrigerator includes a fruit and vegetable fresh-keeping compartment for storing fruits and vegetables and a radio frequency module, wherein the radio frequency module is used to apply a radio frequency electromagnetic field to the fruit and vegetable fresh-keeping compartment. Figure 1 , Figure 1 This is a flow chart of a refrigerator control method provided in an embodiment of the present application. The refrigerator control method includes the following steps S101-S102:

[0054] Step S101: Detecting the maturity of fruits and vegetables in the current fruit and vegetable preservation room;

[0055] Exemplarily, a gas detection device is provided in the fruit and vegetable fresh-keeping chamber. "Detecting the maturity of fruits and vegetables in the current fruit and vegetable fresh-keeping chamber" can be set to detect the amount of characteristic gas generated in the fruit and vegetable fresh-keeping chamber through the gas detection device, and compare the detected amount of characteristic gas generated with the corresponding characteristic value of the pre-stored fruit and vegetable type, so as to obtain the maturity of the fruits and vegetables. In a specific embodiment of the present application, the characteristic gas can be carbon dioxide and / or ethylene. In addition, when the fruits and vegetables are ripe and fresh, the characteristic gas detected can also be ethanol. The controller of the refrigerator can automatically control the radio frequency module according to the maturity of the fruits and vegetables, thereby realizing automatic control of ripening or preserving fruits and vegetables.

[0056] Before detecting the maturity of the fruits and vegetables in the current fruit and vegetable preservation chamber, the control method may further include obtaining the types of fruits and vegetables, and then obtaining the corresponding characteristic values ​​of the pre-stored types of fruits and vegetables. "Obtaining the types of fruits and vegetables" may be set to manually input the types of stored fruits and vegetables by the user, or may be set to obtain the type information of fruits and vegetables through image recognition, smart label scanning or other methods.

[0057] Step S102: Controlling the working state of the radio frequency module according to the maturity to ripen or preserve the fruits and vegetables.

[0058] It should be noted that when the RF module is turned on, the RF electromagnetic field it generates acts on fruits and vegetables, which can improve the respiration of fruits and vegetables and accelerate the ripening of fruits and vegetables. First, the permeability of the cell membrane of fruit and vegetable cells changes in the RF electric field, making it easier for oxygen to enter the cells, thereby changing the internal environment of the cells and increasing the substrates for cell respiration; in addition, the increased permeability of the cell membrane makes it easier for respiratory substrates such as extracellular sugars to enter the cells, providing more energy sources for cell respiration; under the action of the RF electric field, the activity of enzymes related to respiration in the cells will also be enhanced, for example, enzymes such as citrate synthase and isocitrate dehydrogenase involved in aerobic respiration, and enzymes such as cytochrome oxidase in the electron transport chain will increase due to changes in the intracellular environment. The increase in enzyme activity allows each link of respiration to be carried out more efficiently, thereby improving the respiration of fruits and vegetables and promoting energy metabolism. With the increase in the supply of respiratory substrates and the increase in the activity of respiratory enzymes, the aerobic respiration process in fruit and vegetable cells is accelerated, and respiration is improved.

[0059] It is understandable that when the maturity of fruits and vegetables reaches the optimal maturity corresponding to the fruit and vegetable variety, there is no need to continue ripening the fruits and vegetables, and the radio frequency module can be turned off to reduce the respiration of the fruits and vegetables.

[0060] The refrigerator control method provided in the embodiment of the present application automatically controls the working state of the radio frequency module according to the maturity of fruits and vegetables, realizes intelligent ripening or preservation of fruits and vegetables, keeps the fruits and vegetables at a high quality and nutrition, and protects the health of users.

[0061] In some embodiments, controlling the working state of the radio frequency module according to the maturity includes:

[0062] If the current maturity of the fruits and vegetables is less than the preset optimal maturity, the radio frequency module is controlled to turn on based on the first preset frequency to ripen the fruits and vegetables;

[0063] If the current maturity of fruits and vegetables is greater than or equal to the preset optimal maturity, the radio frequency module is controlled to stop working to keep the fruits and vegetables fresh.

[0064] It should be noted that for different types of fruits and vegetables, the parameters such as the gas emitted and the sugar content when they reach the optimal maturity are different. Before controlling the working state of the RF module according to maturity, the refrigerator is set to obtain the type of fruits and vegetables, and obtain the pre-stored optimal maturity of the type of fruits and vegetables according to the type. In this way, by comparing the current maturity of fruits and vegetables with the optimal maturity, it is possible to determine whether to ripen or preserve the fruits and vegetables, thereby realizing intelligent storage of fruits and vegetables.

[0065] The first preset frequency may be 13.56 MHz. The radio frequency module is turned on based on the first preset frequency, and the electromagnetic field generated by the module acts on the fruits and vegetables, thereby ripening the fruits and vegetables.

[0066] In some embodiments, before controlling the RF module to turn on based on the first preset frequency, the control method further includes:

[0067] Get the types of fruits and vegetables;

[0068] Determine the first target power and target ripening time according to the type of fruits and vegetables;

[0069] Controlling the radio frequency module to start based on the first preset frequency includes:

[0070] The radio frequency module is controlled to start the target ripening time based on the first preset frequency and the first target power.

[0071] For different types of fruits and vegetables, due to different tissue structures, the tissues of some types of fruits and vegetables are easily penetrated by radio frequency, while the tissues of some types of fruits and vegetables are difficult to be penetrated by radio frequency. Therefore, the working frequency and ripening time of the radio frequency module can be adjusted in a targeted manner to improve the ripening effect of fruits and vegetables. For example, for leafy vegetables, since their tissue structure is relatively thin, radio frequency is easier to penetrate, and it is not suitable to apply a high-power radio frequency electromagnetic field; for mushrooms, due to their special structure, such as mycelium, it is not suitable to apply a high-power radio frequency electromagnetic field; for fruits, their structure is slightly more complicated than that of leafy vegetables, and they have thicker peels, so relatively high-power radio frequency electromagnetic fields can be applied. In addition, for leafy vegetables and mushrooms, optical fiber temperature sensors can also be set in the space. When the temperature is detected to be higher than a certain value, the radio frequency module is controlled to be turned off to prevent excessive temperature from damaging the fruit and vegetable tissues.

[0072] Optionally, determining the first target power and the target ripening time according to the types of fruits and vegetables may include:

[0073] Acquire a mapping relationship collection, the mapping relationship collection including a mapping relationship between a preset type and a first preset power and a preset ripening time;

[0074] According to the mapping relationship, the first target power corresponding to the type of fruits and vegetables is determined from the first preset power, and the target ripening time corresponding to the type of fruits and vegetables is determined from the preset ripening time.

[0075] Exemplarily, the preset types of fruits and vegetables include leafy vegetables, mushrooms and fruits. The mapping relationship collection includes a mapping relationship between leafy vegetables and the first power and the first duration, a mapping relationship between mushrooms and the second power and the second duration, and a mapping relationship between fruits and the second power and the second duration, wherein the first power, the second power, and the third power increase in sequence, and / or the first duration, the second duration, and the third duration increase in sequence. Optionally, the first power is between 100W and 200W, the first duration is between 5 minutes and 10 minutes, the second power is between 150W and 250W, the second duration is between 6 minutes and 9 minutes, the third power is between 200W and 300W, and the third duration is between 8 minutes and 12 minutes.

[0076] In some embodiments, before detecting the maturity of fruits and vegetables in the fruit and vegetable fresh-keeping chamber, the method further includes:

[0077] The radio frequency module is controlled to be turned on based on a second preset frequency to sterilize the fruit and vegetable preservation chamber, and the second preset frequency is greater than the first preset frequency.

[0078] It should be noted that the radio frequency module sterilizes the fruit and vegetable fresh-keeping room based on the following principles: First, when the radio frequency electromagnetic field with a frequency of the second preset frequency acts on the material containing microorganisms, the water molecules inside it vibrate rapidly and rub against each other in the radio frequency electric field to generate heat. This heat generation is relatively uniform because the radio frequency can make the water molecules inside the material participate in the movement. For microorganisms, as the temperature rises, the proteins in their cells will denature; the radio frequency electromagnetic field with a frequency of the second preset frequency will also interfere with the normal distribution of charged particles and dipoles in the microbial cells in the fruit and vegetable fresh-keeping room, and the ion channels in the cells will be affected by the radio frequency field and ion transport will be disordered; in addition, the cell membrane is composed of a phospholipid bilayer and protein, and the radio frequency field can change the potential and permeability of the cell membrane. For example, under the action of radio frequency, the cell membrane of some microorganisms is destroyed in its original function of controlling the entry and exit of substances into and out of the cell, and important substances in the cell, such as potassium ions, are lost, and some enzymes and other small molecules are leaked; the above aspects can cause the physiological functions of microorganisms to be disordered and eventually die.

[0079] The radio frequency module adopts phase-locked loop frequency synthesis technology, so that it can switch between multiple operating frequencies. The second preset frequency is, for example, 40.68 MHz.

[0080] To improve the sterilization efficiency of the radio frequency module, before controlling the radio frequency module to start based on the second preset frequency, the control method may further include:

[0081] Testing the moisture content of fruits and vegetables;

[0082] Determine the second target power and target sterilization time according to the moisture content;

[0083] Controlling the radio frequency module to start based on the second preset frequency includes:

[0084] The radio frequency module is controlled to start the target sterilization time based on the second preset frequency and the second target power.

[0085] Among them, the moisture content of fruits and vegetables can be detected by setting a hyperspectral detector. According to the moisture content of fruits and vegetables, the operating power and sterilization time of the RF module are determined in a targeted manner, which can improve the sterilization efficiency and realize intelligent sterilization. As for how to determine the second target power and target sterilization time according to the moisture content, it can be determined by comparing the pre-stored mapping relationship between moisture content, power and sterilization time. Exemplarily, when the moisture content of fruits and vegetables is measured to be a high moisture content of more than 90%, the second target power of the RF module is determined to be between 100W and 200W, and the sterilization time is determined to be between 30 seconds and 60 seconds; when the moisture content is measured to be a medium moisture content of 80-90%, the second target power of the RF module is determined to be between 200W and 300W, and the sterilization time is determined to be between 30 seconds and 60 seconds; when the moisture content is measured to be a low moisture content of less than 80%, the second target power of the RF module is determined to be between 100W and 200W, and the sterilization time is determined to be between 30 seconds and 60 seconds.

[0086] In some embodiments, when the maturity of fruits and vegetables reaches the optimum, the RF module can be turned off to cooperate with the controlled atmosphere preservation to preserve the fruits and vegetables so that the fruits and vegetables maintain the current optimum maturity. For example, the fruit and vegetable preservation chamber is also provided with a controlled atmosphere preservation module, which includes a plurality of air outlets, and the materials of the controlled atmosphere films provided at at least two of the air outlets are different, and each air outlet is provided with a damper; after the RF module is controlled to stop working, it also includes:

[0087] Determine the target modified atmosphere membrane according to the type of fruits and vegetables;

[0088] The damper corresponding to the air outlet of the target atmosphere-controlled fresh-keeping module is controlled to open, and the air outlet of the atmosphere-controlled fresh-keeping module is controlled.

[0089] It should be noted that different types of fruits and vegetables have different respiration intensities, so different conditioned atmosphere membrane materials are suitable. Using conditioned atmosphere membrane materials that match them for conditioned atmosphere preservation can enhance the preservation effect of fruits and vegetables. For example, the best conditioned atmosphere membrane materials for leafy vegetables are sulfonated polyetheretherketone (SPEEK) and polyethylene (PE), the best conditioned atmosphere membrane materials for mushrooms are (PP) and sulfonated polyetheretherketone (SPEEK), and the best materials for fruits are polyvinylidene fluoride (PVDF) and sulfonated polyetheretherketone (SPEEK).

[0090] Optionally, the plurality of air outlets include at least one controlled atmosphere membrane with a SPEEK material, one controlled atmosphere membrane with a PP material, and one controlled atmosphere membrane with a PVDF material. When the fruit and vegetable species are leafy vegetables, the damper corresponding to the air outlet with a SPEEK material controlled atmosphere membrane on the controlled atmosphere preservation module is controlled to be opened; when the fruit and vegetable species are mushrooms, the damper corresponding to the air outlet with a PP material controlled atmosphere membrane on the controlled atmosphere preservation module is controlled to be opened; when the fruit and vegetable species are fruits, the damper corresponding to the air outlet with a PVDF material controlled atmosphere membrane on the controlled atmosphere preservation module is controlled to be opened.

[0091] Preferably, each damper can flexibly adjust the opening of the corresponding air outlet, and the refrigerator is also configured to detect the concentration of carbon dioxide in the fruit and vegetable fresh-keeping chamber, and control the movement of the damper according to the carbon dioxide concentration to adjust the opening of the corresponding air outlet. Exemplarily, when it is detected that the carbon dioxide concentration has dropped to an optimal concentration, the damper is controlled to be closed; with the respiration of fruits and vegetables, the carbon dioxide concentration in the fruit and vegetable fresh-keeping chamber will increase. When the increase in carbon dioxide concentration reaches a preset value, such as 10-15%, the corresponding gas-controlled membrane damper is controlled to be opened for a preset time period, such as between 3 and 4 hours, based on a 3 / 4 opening; when the carbon dioxide concentration drops to the optimal concentration again, the damper is closed again; when the increase in carbon dioxide concentration in the fruit and vegetable fresh-keeping chamber reaches the preset value again, the corresponding gas-controlled membrane damper is controlled to be opened for a preset time period, such as between 3 and 4 hours, based on a 1 / 2 opening; when the carbon dioxide concentration drops to the optimal concentration again, the damper is closed again; when the increase in carbon dioxide concentration in the fruit and vegetable fresh-keeping chamber reaches the preset value again, the corresponding gas-controlled membrane damper is controlled to be continuously opened based on a 1 / 4 opening. It is understandable that the damper is opened to the maximum at the beginning in order to quickly reduce the carbon dioxide concentration in the fruit and vegetable preservation room and save time to reach the optimal carbon dioxide concentration. When the carbon dioxide concentration drops excessively, the degree of opening of the damper is reduced to reduce the exposed area of ​​the controlled atmosphere membrane, thereby reducing the rate of carbon dioxide reduction.

[0092] The refrigerator control method provided in the embodiment of the present application automatically controls the working state of the radio frequency module according to the maturity of fruits and vegetables, realizes intelligent ripening or preservation of fruits and vegetables, keeps the fruits and vegetables at a high quality and nutrition, and protects the health of users.
