[0025] Fruits and vegetables contain a large amount of water, which is a necessary condition for maintaining the life activities and fresh quality of fruits and vegetables. After being picked, fruits and vegetables can no longer obtain water supply from the mother body, and during long-term storage, water gradually evaporates. When the dry matter loss (weight loss) of most fruits and vegetables exceeds 5%, obvious characteristics such as withering and a decline in freshness will appear. Especially for fruits, it is impossible to return to their original state after the dry matter loss reaches 5%. The water evaporation of fruits and vegetables is, on the one hand, due to the respiratory action, which emits a part of the water and continuously releases ethylene gas, affecting the physiological activities and nutritional quality of fruits and vegetables during storage; on the other hand, the air humidity in the storage environment is too low, causing fruits and vegetables to wither and reducing their commercial value. The humidity in the fruit and vegetable compartment of a refrigerator is generally required to be around 90% to 95%.

[0026] Ethylene (C2H4) is an organic compound produced by almost all higher plants and some microbial tissues, which can affect the biochemical changes of plants. After being picked, fruits and vegetables still maintain their vitality, carry out respiration, and continuously release ethylene gas. C2H4 is a typical non-polar molecule and is difficult to be adsorbed. The C=C bond and C-H bond are very stable in the air. As a natural plant hormone, that is, a "ripening" hormone, ethylene can have a ripening effect on fruits and vegetables at extremely low concentrations, leading to the senescence and decay of fruits and vegetables, which is an important reason for the large amount of short-term decay of fruits and vegetables. Therefore, it is crucial to control the ethylene content in the refrigerator. In addition, the growth of microorganisms is also one of the important factors affecting the preservation of fruits and vegetables.

[0027] It can be seen from this that the key to the preservation of fruits and vegetables in the refrigerator lies in controlling the humidity of the fruit and vegetable compartment of the refrigerator, inhibiting the growth of microorganisms, and removing the ethylene generated during the storage of fruits and vegetables. For this purpose, the present utility model proposes a refrigerator to achieve the functions of humidifying, sterilizing, and removing ethylene for fruits and vegetables simultaneously.

[0028] Refer to Figure 1 , Figure 1 Figure 10 shows a schematic connection diagram of an ice-making module 100, an electrolysis module 300, and a humidifying module 400 of a refrigerator proposed in an embodiment of the present utility model. As Figure 1 shown, the refrigerator includes a water storage box 200, an electrolysis module 300, and a humidifying module 400. The water storage box 200 is arranged in the refrigerating chamber of the refrigerator. The water storage box 200 is used to store water, and the water stored in the water storage box 200 serves as the water source for the electrolysis module 300 and the humidifying module 400. The water stored in the water storage box 200 needs to serve as the water source for the humidifying module 400, and the water provided by the humidifying module 400 will be discharged into the refrigerating chamber or the fruit and vegetable compartment. Therefore, in order to avoid the food stored in the refrigerating chamber or the fruit and vegetable compartment being contaminated by the electrolyte solution, the water stored in the water storage box 200 cannot be the electrolyte solution added with electrolytes, but can only be the direct drinking water or tap water that can be directly drunk. Subsequently, the water in the water storage box 200 also serves as the water source for the ice-making module 100, and when the ice produced is directly edible, the tap water can be used after boiling and cooling. And, to meet the needs of the electrolysis module 300, the water stored in the water storage box 200 needs to have a certain conductivity. Experiments show that when the conductivity of the water stored in the water storage box 200 is greater than or equal to 5 μS / cm, the conductive demand of the electrolysis module 300 for electrolyzed water can be met.

[0029] Under normal circumstances, the conductivity of pure water is usually less than or equal to 10 μS / cm because pure water has undergone multiple filtration and treatment processes to remove most ions and impurities. The conductivity range of direct drinking water is 0 - 50 μS / cm, indicating that it may contain a small amount of ions but generally maintains good purity. The conductivity of tap water ranges from 125 - 1250 μS / cm because tap water contains various inorganic acids, alkalis, salts, and other substances. The conductivity of distilled water is very low, and theoretically, the limiting conductivity of high-purity water is 0.0547 μS / cm. Thus, the water stored in the water storage box 200 can be tap water, pure water with a conductivity greater than or equal to 5 μS / cm, and direct drinking water.

[0030] The electrolysis module 300 is disposed within the water storage box 200. When the electrolysis module 300 is energized and operating, it can partially electrolyze the water in the water storage box 200, causing the water in the water storage box 200 to contain ozone, an effective substance for sterilization and ethylene removal.

[0031] As an environmentally friendly strong oxidant (E0 = 2.141V, vs. RHE), ozone has a strong bactericidal and disinfection effect and the ability to oxidize and degrade organic pollutants. It has been widely used in the field of water treatment. Ozone can effectively kill bacteria, viruses, and spores, and can convert some refractory organic substances such as ethylene into biodegradable organic substances, playing an important role in water treatment fields such as drinking water disinfection, cyanide wastewater treatment, printing and dyeing wastewater treatment, coking wastewater treatment, and municipal sewage treatment.

[0032] The main methods for generating ozone include radiochemical method, corona discharge method, ultraviolet irradiation method, electrolysis method, etc. The electrolysis method does not require dry air as a raw material and can in-situ electrolyze to produce ozone water without additional auxiliary ozone dissolution equipment, so it is more suitable for application. Currently, the technology for preparing ozone water by electrolysis method has been relatively mature, and existing products include electrolytic ozone mouthwash, fruit and vegetable cleaning machines, etc.

[0033] The basic principle of generating ozone from electrolyzed water is to apply low-voltage direct current to the anode and cathode, causing water molecules to ionize and generate cations and anions. In the regions of high-concentration cations and anions, through the collision and impact of electrons, oxygen free radicals are generated, which then react with oxygen molecules, ultimately producing ozone. This process involves the generation of electrons, the generation of oxygen free radicals, and their reactions with oxygen molecules, jointly promoting the formation of ozone.

[0034] According to the needs of the humidification, sterilization, and ethylene removal sites, the humidification module 400 can be set in the fruit and vegetable compartment or directly in the refrigerator's freezer compartment. The humidification module 400 is connected to the water storage box 200 through the first pipeline 500. When the humidification module 400 is operating, it can drain the ozone-containing water in the water storage box 200 to the freezer compartment or the fruit and vegetable compartment of the refrigerator through the first pipeline 500.

[0035] Specifically, when the humidification module 400 is disposed in the refrigerating chamber, during operation, the humidification module 400 discharges the ozone-containing water in the water storage box 200 to the refrigerating chamber through the first pipeline 500, thereby humidifying and sterilizing the fresh food ingredients stored in the refrigerating chamber and removing ethylene from the interior of the refrigerating chamber.

[0036] When the humidification module 400 is disposed in the refrigerating chamber, during operation, the humidification module 400 discharges the ozone-containing water in the water storage box 200 to the refrigerating chamber through the first pipeline 500. Ozone can sterilize and remove ethylene from the interior space of the fruit and vegetable compartment and the stored fruits and vegetables. At the same time of the sterilization and ethylene removal treatment, the moisture carried by the humidification module 400 humidifies the fruit and vegetable compartment, thereby ensuring the humidity of the fruit and vegetable compartment.

[0037] As described above, the refrigerator of the present utility model adopts the electrolysis module 300 and the humidification module 400 to share a water storage box 200, thereby reducing the components of the humidification, sterilization and ethylene removal treatment devices, simplifying the structures of the electrolysis module 300 and the humidification module 400, reducing the cost of the refrigerator, reducing the occupied space of the electrolysis module and the humidification module, correspondingly increasing the effective volume of the refrigerator, and realizing triple functions of humidification, sterilization and ethylene removal through the electrolysis module 300 and the humidification module 400.

[0038] Refer to Figure 1 , in some embodiments, the refrigerator further comprises an ice making module 100. The ice making module 100 is connected to the water storage box 200 through a second pipeline 600, and ice for household use can be prepared through the ice making module 100. The water storage box 200 serves as a container for storing water for the ice making module 100 and has a large capacity, which can meet the requirements of electrolysis and humidification. Thus, the refrigerator of the present utility model shares the water storage box 200 of the ice making module 100 with the humidification module 400 and the electrolysis module 300, further reducing the accessories of the refrigerator functional modules, reducing the cost of the refrigerator, further increasing the effective volume of the refrigerator, and realizing multiple functions such as ice making, humidification, sterilization and ethylene removal through the electrolysis module 300 and the humidification module 400.

[0039] It can be understood that the ice making module 100 may adopt the ice making module 100 commonly used in the refrigerator field, which is not limited herein.

[0040] Refer to Figure 1 , Figure 2 , in some embodiments, the electrolysis module 300 is disposed at the bottom of the water storage box 200 and on the side of the water storage box 200 away from the refrigerator door, so as to facilitate the connection of the electrolysis module 300 with the refrigerator circuit and reduce the assembly difficulty of the electrolysis module 300.

[0041] Due to the instability of ozone, it is easy to decompose into oxygen. Refer to Figure 1, in this embodiment, the electrolysis module 300 is arranged between the inlets of the first pipeline 500 and the second pipeline 600 and close to the inlets of the first pipeline 500 and the second pipeline 600. When the humidification module 400 performs humidification treatment or the ice-making module 100 makes ice, the ozone active substances generated by the electrolysis module 300 can be pumped away by the water pump of the humidification module 400 or the ice-making module 100 in a relatively short time, so as to avoid the dissipation of ozone along the water storage box, improve the utilization rate of ozone, reduce the decomposition probability of ozone in the water storage box 200, thereby improving the efficiency of the electrolysis module 300, reducing the running time of the electrolysis module 300, and reducing the running cost of the refrigerator.

[0042] In some embodiments, the electrolysis module 300 includes two electrodes, which are arranged at intervals along the height direction of the water storage box 200. The distance between the two electrodes is greater than or equal to 1 mm and less than or equal to 5 mm. After applying low-voltage direct current to the anode and cathode electrodes, the electrolysis module 300 with this structure can better electrolyze water to generate ozone. Moreover, the two electrodes are arranged at intervals along the height direction of the water storage box 200. During electrolysis, ice-making, and humidification operations, the change in the water level in the water storage box 200 can be reflected by the change in the current of the electrolysis module 300. Specifically, when the water level in the water storage box 200 is relatively high and completely submerges the two electrodes of the cathode and the anode, due to the conductivity of water, the electrolysis module 300 is in a conducting state, and the current value of the electrolysis module 300 is relatively large. From this, it can be judged that the electrolysis, ice-making, or humidification operation can proceed normally; when the water level in the water storage box 200 is very low or even in a waterless state, the two electrodes of the electrolysis module 300 are in an open circuit state, and the current value of the electrolysis module 300 is very small, and the water storage box 200 needs to be replenished with water; when there is a certain water level in the water storage box 200, but this water level does not completely submerge the two electrodes of the electrolysis module 300, that is, the water level of the water storage box 200 is between the state where the two electrodes of the electrolysis module 300 are not completely submerged and the waterless state. Within this water level range, the current value of the electrolysis module 300 is also different at different water levels. Thus, it is possible to judge whether the water level of the water storage box 200 meets the requirements of electrolysis, ice-making, or humidification operations according to the magnitude range of the current value of the electrolysis module 300, and then remind the user to add water by means of screen display, app, or voice.

[0043] The electrode used as the anode can be a food-grade electrode with a high oxygen evolution potential, such as using substrates such as titanium and stainless steel, and then doping one or more of precious metals such as pt, Ru, Ir, Co, Ta, etc.; the electrode used as the cathode is usually a food-grade stainless steel with good conductivity. The electrodes used as the anode and the cathode can be porous metal meshes or porous metal plates, and the shapes of the holes on the metal meshes or metal plates can be rectangles, squares, rhombuses, circles, etc. Using porous metal meshes or porous metal plates as the electrodes of the electrolysis module 300 can increase the contact area between the electrodes and water and improve the electrolysis efficiency.

[0044] It can be understood that the two electrodes of the electrolysis module 300 can also be arranged at intervals along the width direction of the water storage box 200, which is not limited herein.

[0045] Referring to Figure 1 , in some embodiments, along the height direction of the water storage box 200, the maximum distance from the inlet end of the first pipeline 500 to the bottom of the water storage box 200 is L1, the maximum distance from the inlet end of the second pipeline 600 to the bottom of the water storage box 200 is L2, and the maximum distance from the upper part of the electrolysis module 300 to the bottom of the water storage box 200 is L3, where L3>L1 and L3>L2. Thus, when the upper part of the electrolysis module 300 just emerges above the water level in the water storage box 200, the water inlets of the first pipeline 500 and the second pipeline 600 are still immersed below the water level in the water storage box 200. After the upper part of the electrolysis module 300 emerges from the water surface in the water storage box 200, the current value of the electrolysis module 300 will change. As the part of the electrolysis module 300 emerging above the water level in the water storage box 200 increases, the current value of the electrolysis module 300 decreases more. By setting the current value when the upper part of the electrolysis module 300 just emerges from the water surface in the water storage box 200 as the warning value, the electrolysis module 300 will send a prompt through the control system at this warning value to remind the user to add water, so as to prevent the water pump of the humidification module 400 or the ice making module 100 from pumping air in vain and extend the service life of the water pump.

[0046] Referring to Figure 1 , in some embodiments, the humidification module 400 is arranged at the top of the fruit and vegetable compartment, and the humidification module 400 has a nozzle or an atomizing sheet 700. When the humidification module 400 is provided with a nozzle, the water containing the active substance ozone can be sprayed onto the fruits or vegetables in the fruit and vegetable compartment through the humidification module 400, so as to sterilize and remove ethylene from the fruits or vegetables in the fruit and vegetable compartment while maintaining the humidity of the fruit and vegetable compartment. When the humidification module 400 is provided with an atomizing sheet 700, first, the water containing the active substance ozone is atomized by the atomizing sheet 700 through the humidification module 400, and then the atomized water is sprayed into the fruit and vegetable compartment. The atomized water contains the active substance ozone for sterilization and ethylene removal, and also carries small-volume water molecules, which can ensure the humidity of the fruit and vegetable compartment while sterilizing and removing ethylene, playing a role in humidification.

[0047] In some embodiments, a humidity sensor is provided in the fruit and vegetable compartment. The ice-making module 100, the electrolysis module 300, the humidification module 400, etc. are controlled by a control module. Among them, the humidity sensor is electrically connected to the control module, and the control module is electrically connected to the electrolysis module 300, the ice-making module 100, and the humidification module 400. The control module obtains humidity information through the humidity sensor and automatically controls the electrolysis module 300 and the humidification module 400 to ensure that the humidity in the fruit and vegetable compartment is controlled within a preset range. And the ice-making module 100 is controlled by the control module to realize the automatic control of the ice-making operation and the ice-making pipeline cleaning operation.

[0048] In some embodiments, the control module is configured such that when the humidity sensor detects that the humidity in the fruit and vegetable compartment is ≤ 80%, the control module starts the electrolysis module 300 and the humidification module 400 to maintain the humidity in the fruit and vegetable compartment at the preset humidity.

[0049] In some other embodiments, the control module is configured such that when the humidity sensor detects that the humidity in the fruit and vegetable compartment > 80%, the control module starts the electrolysis module 300 and the humidification module 400 at a preset time to achieve the functions of sterilization and ethylene removal.

[0050] In some embodiments, the electrolysis module 300 is configured such that the control module controls the electrolysis module 300 to achieve the functions of water addition reminder for the water storage box 200, ice-making pipeline cleaning function, humidification function for the fruit and vegetable compartment, or clean ice preparation function.

[0051] Specifically, referring to Figure 3 , when the control module does not receive the ice-making operation and ice-making pipeline cleaning operation instructions, and the humidity sensor detects that the humidity in the fruit and vegetable compartment is ≤ 80%, the humidity sensor feeds back the humidity information to the control module. The control module issues an instruction to start the electrolysis module 300. The control module obtains the current information of the electrolysis module 300. When the current I of the electrolysis module 300 is greater than 10 μA, after the electrolysis module 300 is turned on for a predetermined time T3, the electrolysis module 300 partially electrolyzes the water in the water storage box 200. The water in the water storage box contains a certain concentration of the active substance ozone. Then, the control module issues an instruction to start the humidification module 400 to perform a humidification operation on the fruit and vegetable compartment through the humidification module 400. During the humidification operation, the fruits or vegetables in the fruit and vegetable compartment are sterilized and ethylene is removed by using the water with the active substance ozone. After the humidification, sterilization, and ethylene removal operations are performed for a predetermined time, the control module issues an instruction to turn off the electrolysis module 300 and the humidification module 400, and the humidification, sterilization, and ethylene removal operations are completed.

[0052] When the control module does not receive the ice-making operation or ice-making pipeline cleaning operation instruction, and the humidity sensor detects that the humidity in the fruit and vegetable compartment is ≤ 80%, the humidity sensor feeds back the humidity information to the control module. The control module issues an instruction to start the electrolysis module 300. When the current I of the electrolysis module 300 is less than or equal to 10 μA, the electrolysis module 300 issues a prompt through the control system to remind the user to add water. After the water addition is completed, the current I of the electrolysis module 300 obtained by the control module at this time is greater than 10 μA. After the electrolysis module 300 is turned on for a predetermined time T3, the control module issues an instruction to start the humidification module 400. The fruit and vegetable compartment is humidified through the humidification module 400. During the humidification operation, the fruits or vegetables in the fruit and vegetable compartment are sterilized and ethylene-removed using water with the active substance ozone. After the humidification, sterilization, and ethylene-removal operations are performed for a predetermined time, the control module issues an instruction to turn off the electrolysis module 300 and the humidification module 400, and the humidification, sterilization, and ethylene-removal operations are completed.

[0053] When the humidity sensor detects that the humidity in the fruit and vegetable compartment is at the preset humidity, the humidity sensor feeds back the humidity information to the control module. The control module issues an instruction to turn off the electrolysis module 300 and at the same time turn off the humidification module 400.

[0054] When the control module does not receive the ice-making operation or ice-making pipeline cleaning operation instruction, and the humidity sensor detects that the humidity in the fruit and vegetable compartment is > 80%, the humidity sensor feeds back the humidity information to the control module. Within a certain time period, the control module issues an instruction to control the electrolysis module 300 to be turned on for a predetermined time T2. The electrolysis module 300 partially electrolyzes the water in the water storage box 200 to produce the active substance ozone. Then, the control module issues an instruction to start the humidification module 400. The fruit and vegetable compartment is humidified through the humidification module 400. During the humidification operation, the fruits or vegetables in the fruit and vegetable compartment are sterilized and ethylene-removed using water with the active substance ozone. After the humidification, sterilization, and ethylene-removal operations are performed for a predetermined time, the control module issues an instruction to turn off the electrolysis module 300 and the humidification module 400, and the humidification, sterilization, and ethylene-removal operations are completed.

[0055] When the control module receives the ice-making operation instruction, the control module issues an instruction to start the electrolysis module 300. When the current I of the electrolysis module 300 is greater than 10 μA, after the electrolysis module 300 is turned on for a predetermined time T1, the water in the water storage box contains a certain concentration of the active substance ozone. The control module issues an instruction to start the ice-making module 100. The ice-making module 100 extracts the water containing a certain concentration of the active substance ozone from the water storage box 200 through the second pipeline 600 and enters the ice-making module 100 to make ice. After preparing a predetermined amount of ice cubes or making ice for a certain time, the control module issues an instruction to turn off the electrolysis module 300 and the ice-making module 100, and the ice-making operation is completed.

[0056] When the control module receives the ice-making operation instruction, the control module issues an instruction to start the electrolysis module 300. The control module obtains the current information of the electrolysis module 300. When the current I of the electrolysis module 300 is less than or equal to 10 μA, the electrolysis module 300 issues a prompt through the control system to remind the user to add water. After the water addition is completed, at this time, the current I of the electrolysis module 300 obtained by the control module is greater than 10 μA. After the electrolysis module 300 starts for a predetermined time T1, the water in the water storage box contains a certain concentration of active substance ozone. The control module issues an instruction to start the ice-making module 100. The ice-making module 100 extracts the water containing a certain concentration of active substance ozone from the water storage box 200 through the second pipeline 600 and enters the ice-making module 100 to make ice. After preparing a predetermined amount of ice cubes or preparing ice cubes for a predetermined time, the control module issues an instruction to turn off the electrolysis module 300 and the ice-making module 100, and the ice-making operation is completed.

[0057] When the control module receives the pipeline self-cleaning operation instruction, the control module issues an instruction to start the electrolysis module 300. The electrolysis module 300 starts. The control module obtains the current information of the electrolysis module 300. When the current I of the electrolysis module 300 is greater than 10 μA, after the electrolysis module 300 starts for a predetermined time, the control module issues an instruction to start the water pump of the ice-making module 100, and uses the water containing a certain concentration of active substance ozone in the water storage box 200 to enter the ice-making pipeline for circulation to clean the ice-making pipeline. After the pipeline self-cleaning starts for a predetermined time, the control module issues an instruction to turn off the electrolysis module 300 and the water pump of the ice-making module 100, and the pipeline self-cleaning operation is completed.
