[0003] Fresh-keeping appliances, such as refrigerators, are a highly mature industry and have become the preferred choice for traditional white goods purchases due to their high penetration rate. Currently, both household and commercial refrigerators primarily utilize phase-change refrigeration technology, which utilizes low temperatures to reduce microbial and enzyme activity, slowing the respiration of food and microorganisms to extend shelf life. However, food and contaminants stored in the refrigerator undergo biochemical reactions such as oxidation and decomposition, resulting in odors inside the refrigerator. These odors can then transfer to the food stored inside, impacting the user experience.

[0050] Exemplary embodiments of the present disclosure will now be described in greater detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of this disclosure thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0051] As shown in Figures 1 to 7, embodiments of the present disclosure provide a fluid processing device 100, a fresh-keeping device 200, and a control method thereof, a storage medium, and an electronic device. The fluid processing device 100 is applied to the fresh-keeping device 200, which can be a refrigerator, a cold chain transport vehicle, or the like.

[0052] As shown in FIG1 , FIG2 and FIG3 , an embodiment of the first aspect of the present disclosure provides a fluid processing device 100. The fluid processing device 100 is used for a fresh-keeping device 200, and includes: an adsorption channel 130, an adsorption module 110, a desorption module 120, a desorption channel 140, and a return air channel 241. The adsorption channel 130 connects the storage compartment 210 of the fresh-keeping device 200 and the adsorption module 110, and the return air channel 241 connects the adsorption module 110 and the storage compartment 210 of the fresh-keeping device 200. The adsorption module 110 is also connected to the desorption channel 140. The adsorption module 110 is used to remove preset molecules from the airflow flowing through it, that is, to adsorb the preset molecules on the adsorption module 110. The desorption module 120 is used to make the airflow in the desorption channel 140 be under preset conditions to desorb the preset molecules in the adsorption module 110, that is, to desorb the preset molecules from the adsorption module 110. The adsorption channel 130 and the desorption channel 140 are isolated from each other, and the desorption module 120 is separately arranged from the adsorption module 110, and the desorption module 120 is arranged away from the adsorption channel 130.

[0053] Fresh-keeping device 200 includes a storage compartment 210 for storing items to be preserved. It also includes a refrigeration module. Storage compartment 210 is connected to an air supply duct 242 and an air return duct 241. Air supply duct 242 directs cool, dry air from the refrigeration module into storage compartment 210, while air return duct 241 directs air from storage compartment 210 back through the refrigeration module. Consequently, the airflow within storage compartment 210 and the airflow through the refrigeration module, guided by air supply duct 242 and air return duct 241, form a circulating airflow path. This allows the airflow within storage compartment 210 to remain at a low temperature for extended periods of time. This low temperature reduces microbial and enzyme activity, slowing the respiration of food and microorganisms and extending the shelf life.

[0054] In this embodiment, the fluid processing device 100 includes an adsorption channel 130, an adsorption module 110, a desorption module 120, and a desorption channel 140. The adsorption channel 130 connects the storage compartment 210 of the fresh-keeping device 200 and the adsorption module 110. As shown in Figures 3 to 5 , the adsorption channel 130 illustrates that airflow from the storage compartment 210 of the fresh-keeping device 200 passes through the adsorption channel 130, then through the adsorption module 110, and then back to the storage compartment 210 via the return air channel 241. Therefore, odors generated by oxidation and decomposition of the objects to be preserved in the storage compartment 210 enter the adsorption module 110 after passing through the adsorption channel 130. The adsorption module 110 can remove predetermined molecules from the airflow passing through the adsorption module 110. This predetermined molecules can be odor molecules, indicating that the adsorption module 110 has the function of removing odors. This results in a fresher airflow returning to the refrigeration module through the return air duct 241, reducing the odor of the dry, cold airflow flowing back into the storage compartment 210 through the supply air duct 242. This results in a fresher airflow within the storage compartment 210, reducing the impact of odor on fresh items and improving the user experience. After multiple cycles of this airflow, the odor will gradually decrease or even be eliminated.

[0055] It is understood that the preset molecules may also include water molecules, and thus the adsorption module 110 may also be a moisture absorption module to reduce the humidity of the airflow within the storage compartment 210, thereby extending the shelf life of the objects to be preserved and reducing the generation of odor within the storage compartment 210. Specifically, the preset molecules may include odor molecules and water molecules.

[0056] Among them, the adsorption module 110 is connected to both the desorption channel 140 and the adsorption channel 130. The desorption channel 140 can be shown as the dotted line in Figures 3 to 5. The desorption module 120 is used to make the airflow in the desorption channel 140 be under preset conditions to desorb the preset molecules adsorbed by the adsorption module 110. Therefore, the desorption module 120 can be used to desorb the preset molecules in the adsorption module 110 connected to the desorption channel 140, thereby restoring the adsorption capacity of the adsorption module 110. As a result, the adsorption time of the adsorption module 110 is extended, the adsorption capacity of the adsorption module 110 is improved, and the adsorption module 110 is avoided. The problem of losing adsorption capacity after adsorption saturation affects the deodorization effect, or the need to replace a new adsorption module 110 with a high cost is avoided. In other words, in the fluid treatment device 100 provided in this embodiment, the adsorption module 110 has a desorption regeneration capability under the action of the desorption module 120, thereby ensuring a good deodorization effect and saving usage costs.

[0057] The preset conditions may include desorption temperature and / or desorption pressure. For example, the desorption module 120 may maintain the airflow within the desorption channel 140 at a preset desorption temperature to desorb the preset molecules from the adsorption module 110. In this case, the desorption module 120 may have a heating structure. Alternatively, the desorption module 120 may maintain the airflow within the desorption channel 140 at a preset desorption pressure to desorb the preset molecules from the adsorption module 110. In this case, the desorption module 120 may have a pressure regulating structure.

[0058] The adsorption channel 130 and the desorption channel 140 are isolated from each other, and the desorption module 120 is disposed separately from the adsorption module 110, and / or the desorption module 120 is disposed away from the adsorption channel 130. This configuration enables the desorption module 120 to process the airflow within the desorption channel 140 so that the airflow within the desorption channel 140 meets preset conditions, and the desorption module 120 has little or no effect on the airflow within the adsorption channel 130. Therefore, the refrigeration module, the adsorption module 110, and the desorption module 120 of the fresh-keeping device 200 can be controlled to operate simultaneously for at least one operating period, with the adsorption module 110 adsorbing predetermined molecules flowing from the storage compartment 210 into the adsorption channel 130. Simultaneously, the desorption module 120 is used to adjust the airflow within the desorption channel 140 to meet preset conditions to desorb the predetermined molecules from the adsorption module 110. Compared with the configuration in which the refrigeration module and the desorption module cannot work simultaneously, that is, they need to work at intervals, this configuration avoids the need for the refrigeration module to stop working when the desorption module 120 is working, thereby affecting the refrigeration effect of the storage compartment 210 .

[0059] The fluid handling device 100 of this embodiment can reasonably control the operating status of the refrigeration module according to demand, without being affected by the operating status of the desorption module 120, which helps ensure a good cooling effect for the storage compartment 210. At the same time, because the adsorption channel 130 and the desorption channel 140 are isolated from each other, the airflow flowing out of the desorption channel 140 does not flow into the storage compartment 210. This can reduce the impact of the airflow in the desorption channel 140 on the airflow in the storage compartment 210, further ensuring a good cooling effect for the airflow in the storage compartment 210. In other words, even when the desorption module 120 is desorbing the preset molecules in the adsorption module 110, the refrigeration module can continue to operate to ensure a good cooling effect for the storage compartment 210.

[0060] In some possible embodiments provided by the present disclosure, the desorption module 120 is connected to the inner wall and / or outer wall of the desorption channel 140 and / or the outer wall of the adsorption module 110 .

[0061] The desorption module 120 can be connected to the inner wall, outer wall, or both inner and outer walls of the desorption channel 140, or to the outer wall of the adsorption channel 130, or to the outer wall of the adsorption module 110. Thus, when the desorption module 120 is in operation, it can quickly bring the airflow within the desorption channel 140 to a predetermined condition, allowing the predetermined molecules in the adsorption module 110 connected to the desorption channel 140 to disengage, thus restoring the adsorption capacity of the adsorption module 110. This configuration can also reduce the impact of the desorption module 120 on the airflow within the adsorption channel 130.

[0062] It is understandable that in order to reduce the impact of the desorption module 120 on the airflow in the adsorption channel 130 , the desorption module 120 may be disposed on the inner wall and / or outer wall of the desorption channel 140 away from the adsorption channel 130 .

[0063] In some possible embodiments provided by the present disclosure, the fluid treatment device 100 includes a shell, the adsorption module 110 is located in the shell, and a first space and a second space isolated from each other are formed in the shell, wherein the first space is respectively connected to the adsorption channel 130 and the return air channel 241, and the desorption channel 140 is connected to the second space. In some embodiments, the desorption module 120 can be connected to the shell. For example, the desorption module 120 can be set on the outer wall surface of the shell and connected to the second space in the shell. There is a partition between the first space and the second space, thereby reducing or eliminating the phenomenon of gas in the adsorption channel 130 and the desorption channel 140 entering the shell and causing movement and mixing; and reducing or eliminating the phenomenon of gas in the first space and the second space causing mutual movement and mixing.

[0064] The desorption module 120 is connected to the outside of the housing, which facilitates the disassembly and assembly of the desorption module 120 and the housing. The desorption module 120 can be directly repaired and replaced outside the housing, which is convenient to operate. Compared with installing the desorption module 120 inside the housing and requiring the housing to be disassembled for repair and replacement, this is conducive to improving the efficiency of repair and replacement. At the same time, the desorption module 120 is connected to the outside of the housing corresponding to the desorption channel 140. Therefore, the operation of the desorption module 120 can quickly make the airflow in the desorption channel 140 reach the preset conditions, so that the preset molecules in the adsorption module 110 connected to the desorption channel 140 are separated, so that the adsorption module 110 can restore its good adsorption capacity. At the same time, the operation of the desorption module 120 does not affect the airflow state in the adsorption channel 130, thereby ensuring that the adsorption module 110 and the desorption module 120 can operate simultaneously, that is, the refrigeration module and the desorption module 120 of the fresh-keeping device 200 can operate simultaneously at least at one time. The desorption module 120 may be connected to the housing by at least one of bolts, a clamping structure, a mortise and tenon structure, and an adhesive.

[0065] In some possible embodiments provided by the present disclosure, the fluid treatment device 100 further includes a power unit that drives the adsorption module to move relative to the adsorption channel 130 and the desorption channel 140 .

[0066] Thus, the power unit can be used to alternately connect different portions of the adsorption module 110 to the adsorption channel 130 and the desorption channel 140. Since the adsorption module 110 connected to the adsorption channel 130 can adsorb the predetermined molecules within the adsorption channel 130, the adsorption module 110 connected to the desorption channel 140 can desorb the predetermined molecules under the influence of the airflow in the desorption channel 140 under the predetermined conditions, thereby restoring the adsorption capacity of the adsorption module 110 in that region. Thus, as the power unit drives the adsorption module 110 to move relative to the adsorption channel 130 and the desorption channel 140, the predetermined molecules within the adsorption channel 130 can be sequentially adsorbed by different portions of the adsorption module 110, and the desorption module 120 can sequentially desorb different portions of the adsorption module 110 to restore their adsorption capacity, thereby gradually restoring the adsorption capacity of the entire adsorption module 110 over and over again. This achieves regeneration of the adsorption capacity of the adsorption module 110, further extending the adsorption time and adsorption capacity of the adsorption module 110, avoiding the need to replace the adsorption module 110, and thus saving operating costs.

[0067] Specifically, the power unit can be a drive motor (i.e., an electric drive), a pneumatic drive, a hydraulic drive, etc. Among them, the adsorption module 110 is a turntable, which can optionally be a circular turntable. The power unit is connected to the turntable drive to drive the turntable to rotate. During the rotation of the turntable, the part of the turntable connected to the adsorption channel 130 can adsorb the preset molecules in the adsorption channel 130. When the part of the turntable is rotated to be connected to the desorption channel 140, the airflow under preset conditions in the desorption channel 140 can desorb the preset molecules in the part of the turntable, thereby making the part of the turntable have the ability to adsorb the preset molecules again. Therefore, when this part of the turntable rotates again to be connected to the adsorption channel 130, it has a good ability to adsorb the preset molecules, thereby avoiding the situation where the adsorption capacity of this part of the turntable is saturated and cannot adsorb the preset molecules.

[0068] In the above embodiment, a partition is provided in the shell to isolate the first space and the second space, wherein the first space is connected to the adsorption channel 130 and the return air channel 241 respectively, and the second space is connected to the desorption channel. The provision of the partition is conducive to isolating the first space and the second space, improving the independence of the desorption channel 140 and the adsorption channel 130, and reducing the interconnectivity of the airflow in the desorption channel 140 and the adsorption channel 130 in the shell, thereby allowing the desorption channel 140 and the adsorption channel 130 to operate independently of each other, so that the adsorption module 110 and the desorption module 120 can work independently without affecting each other.

[0069] Among them, the adsorption module 110 can move relative to the partition so that the setting of the partition does not interfere with the movement of the turntable. In some embodiments, the partition and the turntable gap of the adsorption module 110 are matched, and the gap is small to reduce the intercommunication of the gas in the first space and the second space. In other embodiments, there is good sealing between the turntable and the partition to block the intercommunication of the gas in the first space and the second space, ensuring that the desorption channel 140 and the adsorption channel 130 are independent of each other. That is to say, during the rotation of the turntable, the airflows of the adsorption channel 130 and the desorption channel 140 are separated and kept relatively sealed after entering the shell. The circulating airflow of the adsorption channel 130 passes through the partition as little as possible to reach the desorption channel 140, and the circulating airflow of the desorption channel 140 also passes through the partition as little as possible to reach the adsorption channel 130.

[0070] In some possible embodiments provided by the present disclosure, the airflow circulates between the adsorption module 110, the desorption channel 140 and the desorption module 120. The air inlet of the adsorption module 110 is connected to the desorption channel 140, the air outlet of the desorption channel 140 is connected to the desorption module 120, and the desorption module 120 is connected to the adsorption module 110. Optionally, the desorption module 120 is arranged close to the adsorption module 110 to minimize the distance between the desorption module 120 and the adsorption module 110, so that the desorption module 120 can quickly process the airflow near the adsorption module 110 to meet the preset conditions, so as to improve the desorption efficiency of the adsorption module 110. During the rotation of the adsorption module 110 around the axis, the desorption module 120 can perform desorption operations on different parts of the entire adsorption module 110 in turn to achieve the regeneration adsorption capacity of the turntable.

[0071] As shown in Figures 3 to 5, in some possible embodiments provided by the present disclosure, the fluid treatment device 100 also includes an air supply unit 160, which is located in the desorption channel 140 and blows the air flow through the desorption module 120 to the adsorption module 110 to drive the air flow to circulate between the air supply unit 160, the desorption module 120 and the adsorption module 110.

[0072] Thus, the airflow in the desorption channel 140 is processed by the desorption module 120 to meet the preset conditions. When the air supply unit 160 is in operation, the airflow meeting the preset conditions can flow through the adsorption module 110 to desorb the predetermined molecules adsorbed by the adsorption module 110, thereby ensuring a good desorption effect. The air supply unit 160 can be a fan.

[0073] In some possible embodiments provided by the present disclosure, the adsorption module 110 includes a moisture-absorbing material and / or a deodorizing material.

[0074] Examples of hygroscopic materials include zeolite, modified / synthetic zeolite, molecular sieves (including but not limited to zeolite molecular sieves, A / X / Y molecular sieves, ZSM molecular sieves, Beta molecular sieves, etc.), polymeric desiccant, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, and other materials with hygroscopic properties. Polymeric desiccant, also known as polymeric adsorbents, have lower regeneration temperatures than traditional silica gel, activated carbon, and molecular sieve adsorbents.

[0075] The deodorizing material may be, for example, zeolite, modified / synthetic zeolite, molecular sieve (including but not limited to zeolite molecular sieve, A / X / Y type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.), or a polymer deodorant.

[0076] In one embodiment, the adsorption module 110 may be a moisture absorption and dehumidification rotary disk or a deodorization rotary disk. The moisture absorption and dehumidification rotary disk or the deodorization rotary disk may be made of porous materials such as zeolite, molecular sieve, metal organic framework (MOF) material, covalent organic framework (COFs), nanocarbon, silica, etc. In one embodiment, the moisture absorption and dehumidification rotary disk or the deodorization rotary disk may also be filled with granular solids or particles made of at least one of the above porous materials.

[0077] In one embodiment, the moisture absorption and dehumidification turntable or the deodorization turntable may be a honeycomb or corrugated turntable carrying a moisture absorber or deodorizer, which can adsorb and desorb / desorb absorbed water vapor or odor to achieve repeated desorption and regeneration.

[0078] In one embodiment, a moisture absorption and dehumidification rotary disc or a deodorization rotary disc includes an inorganic or organic fiber carrier (such as ceramic, glass fiber, MOFs, COFs, cordierite, etc.), coated with a moisture absorbent or deodorant such as a molecular sieve. The molecular sieve is evenly distributed between and on the surface of the fiber carrier to absorb moisture or odor from the airflow. The molecular sieve may include single crystal molecular sieves such as A molecular sieve, X / Y molecular sieve, ZSM molecular sieve, Beta molecular sieve, or mixed crystal molecular sieves.

[0079] In some possible embodiments provided by the present disclosure, the desorption module 120 includes at least one of the following: a heater, an ultrasonic generator, and a microwave generator.

[0080] In other words, the desorption module 120 is a heating structure that is used to maintain the airflow in the desorption channel 140 at a preset temperature to desorb predetermined molecules from the adsorption module 110. The preset temperature may be the desorption temperature of the adsorption module 110. The desorption module 120 may be any one, any two, or all of a heater, an ultrasonic generator, or a microwave generator. It is understood that the heat generated by the desorption module may also come from resistive heating, waste heat conducted by a heat pipe, or heat dissipation by a condenser.

[0081] As shown in Figures 3 to 5, in some possible embodiments provided by the present disclosure, the inlet and outlet of the desorption channel 140 are both connected to the external environment, and the airflow flows unidirectionally between the adsorption module 110, the desorption channel 140 and the desorption module 120. Specifically, the desorption channel 140 includes a first branch and a second branch, and the inlet and outlet of the first branch of the desorption channel 140 are both connected to the external environment. The first branch of the desorption channel 140 connects the external environment and the desorption module 120, the adsorption module 110 and the desorption module 120 are connected, and the second branch of the desorption channel 140 connects the adsorption module 110 and the environment. Optionally, the desorption module 120 is arranged close to the adsorption module 110. The air supply unit 160 is arranged in the first branch of the desorption channel 140, and blows the airflow through the desorption module 120 to the adsorption module 110, and then discharges it into the environment through the second branch of the desorption channel 140.

[0082] In this embodiment, the desorption channel 140 and the external environment form an air circulation path, making the desorption channel 140 and the adsorption channel 130 independent of each other. Specifically, the airflow from the external environment flows to the desorption module 120 through the inlet of the first branch of the desorption channel 140. After being processed by the desorption module 120 to meet preset conditions, it passes through the adsorption module 110 connected to the desorption channel 140 to desorb the preset molecules adsorbed by the adsorption module 110. After that, it flows to the external environment through the outlet of the second branch of the desorption channel 140. In other words, the airflow flowing out of the desorption channel 140 does not circulate, nor does it return to the storage compartment 210. This reduces the impact of the airflow discharged through the second branch of the desorption channel 140 on the storage compartment 210 of the fresh-keeping device 200.

[0083] In some possible embodiments provided by the present disclosure, the fluid treatment device 100 further includes: a digestion module (not shown in the figure), which is arranged downstream of the desorption module and performs digestion treatment on the airflow flowing through it.

[0084] When the airflow flows unidirectionally between the adsorption module 110, the desorption channel 140 and the desorption module 120, the inlet of the first branch of the desorption channel 140 is connected to the external environment, and the outlet of the second branch of the desorption channel 140 is connected to the digestion module, which digests the airflow passing through it and discharges it to the external environment.

[0085] In this embodiment, the desorption channel 140, the external environment, and the digestion module form a closed airflow passage, making the desorption channel 140 independent of the adsorption channel 130. Specifically, the airflow from the external environment flows to the desorption module 120 through the inlet of the first branch of the desorption channel 140. After being processed by the desorption module 120 to meet the preset conditions, the preset molecules adsorbed by the adsorption module 110 are desorbed. Then, the airflow flows to the digestion module through the outlet of the second branch of the desorption channel 140. After being digested by the digestion module, the airflow is discharged directly to the external environment through the outlet of the second branch of the desorption channel 140 instead of being discharged directly to the external environment. As a result, the impact of the airflow discharged through the second branch of the desorption channel 140 on the external environment can be reduced.

[0086] In some possible embodiments provided by the present disclosure, when the airflow circulates between the adsorption module 110, the desorption channel 140, and the desorption module 120, the digestion module is disposed in the desorption channel 140. The airflow in the desorption channel 140 is processed by the desorption module 120 to meet the preset conditions. When the air supply unit 160 is in operation, the airflow that has met the preset conditions is allowed to flow through the adsorption module 110 to desorb the preset molecules adsorbed by the adsorption module 110. The airflow that has flowed through the adsorption module 110 flows into the digestion module, and after being digested by the digestion module, is blown back to the desorption module 120 through the air supply unit 160 to enter the next cycle.

[0087] Among them, the digestion method of the digestion module can be to use catalysts, enzymes, ultraviolet rays, electrolysis, thermal decomposition or chemical digesters for digestion, or the airflow discharged from the outlet of the desorption channel 140 can be discharged into a liquid or solid solvent, and the solvent is used to dissolve the odor molecules to achieve the digestion effect. It is understandable that the digestion module can be connected to the external environment to achieve the discharge of the digested gas. Specifically, taking the digestion module as ultraviolet rays as an example, ultraviolet-excited titanium catalysts can be used to decompose odorous organic molecules into water and carbon dioxide to achieve the digestion treatment of the airflow discharged from the outlet of the desorption channel 140, wherein the carbon dioxide can be discharged to the external environment. It is understandable that under this setting, the digestion module can also be provided with a water storage tank to accommodate the decomposed liquid.

[0088] In some possible embodiments provided by the present disclosure, the fluid treatment device 100 further includes a sterilization module (not shown in the figure) to sterilize the airflow.

[0089] When the airflow flows unidirectionally between the adsorption module 110, the desorption channel 140, and the desorption module 120, the inlet of the first branch of the desorption channel 140 is connected to the external environment, and the outlet of the second branch of the desorption channel 140 is connected to the sterilization module and / or the digestion module. The sterilization module sterilizes the airflow passing through it, and / or the digestion module digests the airflow passing through it and discharges it to the external environment. This improves the sterility of the airflow discharged to the external environment through the second branch of the desorption channel 140 and reduces contamination to the external environment. In other embodiments, a sterilization module may also be provided in the adsorption channel 130 and / or the return air channel 241.

[0090] Specifically, the airflow from the external environment flows to the desorption module 120 through the first branch of the desorption channel 140. After being processed by the desorption module 120 to reach the preset conditions, the preset molecules adsorbed by the adsorption module 110 are desorbed. Then, the airflow flows to the sterilization module through the second branch of the desorption channel 140, and then flows to the digestion module. After being digested by the digestion module, the airflow replaces the second branch of the desorption channel 140 and is directly discharged to the external environment. Therefore, the impact of the airflow discharged through the second branch of the desorption channel 140 on the external environment can be reduced.

[0091] In some possible embodiments provided by the present disclosure, when the airflow circulates between the adsorption module 110, the desorption channel 140 and the desorption module 120, the sterilization module and the digestion module are both arranged in the desorption channel 140. The airflow in the desorption channel 140 will be processed by the desorption module 120 to meet the preset conditions. When the air supply unit 160 is working, the airflow that meets the preset conditions can flow through the adsorption module 110 to desorb the preset molecules adsorbed by the adsorption module 110. The airflow flowing through the adsorption module 110 flows into the sterilization module and then flows through the digestion module (or flows through the digestion module and then flows through the sterilization module), and then is blown to the desorption module 120 again through the air supply unit 160 to enter the next cycle. In some possible embodiments, the setting positions of the sterilization module and the digestion module can be interchangeable.

[0092] As shown in Figures 1 to 5 , an embodiment of the second aspect of the present disclosure provides a fresh-keeping device 200, comprising a storage compartment 210 and a fluid handling device 100 according to any embodiment of the first aspect. Because the fresh-keeping device 200 includes the fluid handling device 100 according to any embodiment of the first aspect, it possesses all the technical effects of the aforementioned fluid handling device 100, and a detailed description thereof will not be repeated here.

[0093] As shown in Figures 3 to 5, in some possible embodiments provided by the present disclosure, the fresh-keeping device 200 also includes: a refrigeration module, an air supply channel 242 for introducing the dry and cold airflow passing through the refrigeration module into the storage compartment 210, a return air channel 241 for guiding the airflow flowing out of the storage compartment 210 to flow through the refrigeration module, a control device, connected to the refrigeration module and the fluid processing device 100, and the control device is configured to control the refrigeration module and the desorption module 120 of the fluid processing device 100 to operate simultaneously for at least one working period.

[0094] As a result, the operating status of the refrigeration module can be rationally controlled based on demand without being affected by the operating status of the desorption module 120, which helps ensure a good cooling effect for the storage compartment 210. Furthermore, because the airflows in the adsorption channel 130 and the desorption channel 140 are isolated from each other, the airflow from the desorption channel 140 does not flow into the storage compartment 210, or flows only a very small amount. This reduces the impact of the airflow in the desorption channel 140 on the airflow in the storage compartment 210, further ensuring a good cooling effect for the airflow in the storage compartment 210.

[0095] As shown in Figures 3 to 5, in some possible embodiments provided by the present disclosure, the storage compartment 210 includes a freezer compartment 211, and the refrigeration module includes an evaporator 270, a compressor 280, a condenser 250, and a throttling element 260, which are connected in sequence through a refrigerant pipeline to form a circulation path. The evaporator 270 is at least partially located in the freezer compartment 211, and the control device is connected to the compressor 280 to control the start and stop state (or working state) of the compressor 280, and to enable the compressor 280 and the desorption module 120 to operate simultaneously for at least one working period.

[0096] The evaporator 270 is located in the freezer compartment 211 to cool the freezer compartment 211. Specifically, the control device controls the operation of the compressor 280 of the refrigeration module, so that the refrigerant flows through the refrigerant circulation path formed by the evaporator 270, the compressor 280, the condenser 250, and the throttling element 260 to cool the evaporator 270. As a result, the temperature of the freezer compartment 211 can be reduced, and the freezer compartment 211 can be cooled.

[0097] It is understandable that when the storage compartment 210 also includes other compartments, the evaporator 270 can also be located in the other storage compartments 210 to cool the corresponding storage compartments 210, or, only the evaporator 270 in the freezer compartment 211 can be used through the air supply channel 242 to achieve indirect cooling of the other storage compartments 210.

[0098] As shown in Figure 3, in some possible embodiments provided by the present disclosure, the storage compartment 210 also includes a refrigerated compartment 212, the freezer compartment 211 is provided with a first air inlet and a first air outlet, the refrigerated compartment 212 is provided with a second air inlet and a second air outlet, the air supply channel 242 connects the first air outlet and the second air inlet, the second air outlet is connected to the adsorption channel 130 of the fluid processing device, and the return air channel 241 connects the adsorption module 110 of the fluid processing device 100 and the first air inlet; wherein, the fresh-keeping device 200 also includes a fan 290 located in the air supply channel 242 or the return air channel 241.

[0099] In this embodiment, the storage compartment 210 of the fresh-keeping device 200 includes a freezer compartment 211 and a refrigerator compartment 212. The air supply duct 242 connects the first air outlet of the freezer compartment 211 and the second air inlet of the refrigerator compartment 212. The adsorption duct 130 connects the second air outlet of the refrigerator compartment 212 and the adsorption module 110. The return air duct 241 connects the adsorption module 110 and the first air inlet of the freezer compartment 211. Thus, under the action of the fan 290, the dry cold air near the evaporator 270 flows through the freezer compartment 211 and the air supply duct 242 to the refrigerator compartment 212. The air in the refrigerator compartment 212 flows through the adsorption duct 130 to the adsorption module 110 and finally flows back into the freezer compartment 211 through the return air duct 241. This achieves air circulation, and the adsorption module 110 adsorbs the predetermined molecules in the airflow.

[0100] The evaporator 270 of the refrigeration module is located in the freezer compartment 211, keeping the air temperature in the freezer compartment 211 low, thereby cooling the freezer compartment 211. The dry, cold air near the evaporator 270, driven by the fan 290, flows through the freezer compartment 211 and into the refrigeration compartment 212 via the air supply duct 242, thereby cooling the refrigeration compartment 212. The airflow flowing from the refrigerated compartment 212 into the return air duct 241 may carry predetermined molecules, such as odor molecules and / or moisture molecules. Since the adsorption channel 130 of the fluid treatment device 100 is connected to the adsorption module 110, the airflow flowing out of the refrigerated compartment 212 can be fed into the adsorption module 110 via the adsorption channel 130, where the predetermined molecules in the airflow are adsorbed. The treated airflow then flows into the return air duct 241, re-flows into the freezer compartment 211, and then flows into the refrigerated compartment 212 again via the supply air duct 242. This effectively treats the airflow within the freezer compartment 211 and the refrigerated compartment 212, such as reducing the content of odor molecules and / or moisture molecules in the airflow within the freezer compartment 211 and the refrigerated compartment 212, thereby achieving odor removal and / or dehumidification. It is understood that the fluid treatment device 100 in this embodiment can be understood as a single-cycle system, and the fresh-keeping device 200 in this embodiment employs air cooling.

[0101] The fan 290 can be located in the return air channel 241 or in the supply air channel 242, so that the airflow in the freezing compartment 211, the supply air channel 242, the refrigeration compartment 212, the adsorption channel 130, the adsorption module 110, and the return air channel 241 forms a circulation path.

[0102] It is understood that, under the action of the power unit, the portion of the adsorption module 110 adsorbed with the predetermined molecules can move to communicate with the desorption channel 140. Thus, under the action of the desorption module 120 and the air supply unit 160, the predetermined molecules adsorbed in the adsorption module 110 are desorbed by the airflow in the desorption channel 140 under predetermined conditions. As shown in FIG4 , in some possible embodiments provided by the present disclosure, the storage compartment 210 further includes a variable temperature compartment 213, which is provided with a third air inlet and a third air outlet. The third air inlet is connected to the air supply channel 242 via a pipeline, and the third air outlet is connected to the adsorption module 110 of the fluid treatment device 100 via the adsorption channel 130.

[0103] In this embodiment, the storage compartment 210 of the fresh-keeping device 200 includes a freezer compartment 211, a refrigerator compartment 212, and a variable temperature compartment 213. Since the air supply channel 242 connects the first air outlet of the freezer compartment 211 and the second air inlet of the refrigerator compartment 212, the third air inlet of the variable temperature compartment 213 is connected to the air supply channel 242 through a pipeline, the third air outlet of the variable temperature compartment 213 is connected to the adsorption channel 130, the adsorption channel 130 is connected to the adsorption module 110, and the return air channel 241 connects the adsorption module 110 and the first air inlet of the freezer compartment 211. Thus, under the action of the fan 290, the dry cold air near the evaporator 270 flows through the freezer compartment 211 and the air supply channel 242 to the refrigeration compartment 212 and the temperature-variable compartment 213. The air in the refrigeration compartment 212 and the temperature-variable compartment 213 flows into the adsorption module 110 through the adsorption channel 130, and then flows back into the freezer compartment 211 through the return air channel 241, thereby realizing air circulation.

[0104] The evaporator 270 of the refrigeration module is located in the freezer compartment 211, keeping the air temperature in the freezer compartment 211 low, thus achieving the cooling function of the freezer compartment 211. The dry, cold air near the evaporator 270, driven by the fan 290, flows through the freezer compartment 211 via the air supply duct 242 to the refrigeration compartment 212 and the variable temperature compartment 213, thereby achieving the cooling function for the refrigeration compartment 212 and the variable temperature compartment 213. The airflow flowing from the refrigerated compartment 212 and the temperature-variable compartment 213 into the adsorption channel 130 and the airflow flowing from the temperature-variable compartment 213 into the adsorption channel 130 may carry predetermined molecules, which may be odor molecules and / or moisture molecules. Since the adsorption channel 130 of the fluid treatment device 100 is connected to the adsorption module 110, the predetermined molecules in the airflow flowing from the refrigerated compartment 212 and the temperature-variable compartment 213 into the adsorption channel 130 can be adsorbed. The treated airflow then flows into the return air channel 241 and re-flows into the freezer compartment 211. It then flows through the supply air channel 242 and again into the refrigerated compartment 212 and the temperature-variable compartment 213. Thus, the airflow in the freezer compartment 211, the refrigerated compartment 212, and the temperature-variable compartment 213 is treated, for example, the content of odor molecules and / or moisture molecules in the airflow in the freezer compartment 211, the refrigerated compartment 212, and the temperature-variable compartment 213 can be reduced, thereby achieving odor removal and / or dehumidification. It can be understood that the fluid processing device 100 in this embodiment can be understood as a double circulation method, and the fresh-keeping equipment 200 in this embodiment can be understood as air-cooled refrigeration.

[0105] The fan 290 can be located in the return air duct 241 or the supply air duct 242, so that the airflow in the freezing compartment 211, the supply air duct 242, the refrigeration compartment 212 / the temperature-changing compartment 213, the adsorption channel 130, the adsorption module 110, and the return air duct 241 forms a circulation path. It is understood that the compressor 280 and the fan 290 can operate synchronously.

[0106] It can be understood that the part of the adsorption module 110 that adsorbs the preset molecules can move to communicate with the desorption channel 140. Thus, under the action of the desorption module 120 and the air supply part 160, the preset molecules are desorbed by utilizing the airflow under preset conditions in the desorption channel 140.

[0107] As shown in Figure 5, in some possible embodiments provided by the present disclosure, the storage compartment 210 also includes a refrigerated compartment 212, the freezer compartment 211 is provided with a first air inlet and a first air outlet, the refrigerated compartment 212 is provided with a second air inlet, a second air outlet, a third air inlet, and a third air outlet, the air supply channel 242 connects the first air outlet and the second air inlet, the second air outlet is connected to the fluid processing device 100, and the return air channel 241 includes a first sub-air duct 2411 connecting the adsorption module 110 of the fluid processing device 100 and the third air inlet, and a second sub-air duct 2412 connecting the third air outlet and the first air inlet; wherein, the fresh-keeping device 200 also includes a fan 290 located on the first sub-air duct 2411 or the air supply channel 242 or the adsorption channel 130, and the adsorption module 110 of the fluid processing device 100 is connected to the first sub-air duct 2411.

[0108] In this embodiment, the storage compartment 210 of the fresh-keeping device 200 includes a freezer compartment 211 and a refrigerator compartment 212. Since the air supply channel 242 connects the first air outlet of the freezer compartment 211 and the second air inlet of the refrigerator compartment 212, the adsorption channel 130 of the fluid processing device 100 connects the second air outlet and the adsorption module 110 of the fluid processing device 100, the first sub-duct 2411 of the return air channel 241 connects the adsorption module 110 and the third air inlet of the refrigerator compartment 212, and the second sub-duct 2412 of the return air channel 241 connects the third air outlet of the refrigerator compartment 212 and the first air inlet of the freezer compartment 211. Thus, under the action of fan 290, the dry cold air near evaporator 270 flows through freezer compartment 211 and air supply duct 242 to refrigeration compartment 212. The air in refrigeration compartment 212 flows through adsorption duct 130 into adsorption module 110, then flows back into refrigeration compartment 212 through first sub-duct 2411 of return air duct 241, and returns to freezer compartment 211 through second sub-duct 2412 of return air duct 241, thus achieving air circulation. It can be understood that this type of fresh-keeping device 200 can be understood as a direct cooling refrigeration method.

[0109] The evaporator 270 of the refrigeration module is located in the freezer compartment 211, keeping the air temperature in the freezer compartment 211 low, thereby cooling the freezer compartment 211. The dry, cold air near the evaporator 270, driven by the fan 290, flows through the freezer compartment 211 and into the refrigeration compartment 212 via the air supply duct 242, thereby cooling the refrigeration compartment 212. The airflow flowing from the refrigerated compartment 212 into the adsorption channel 130 carries predetermined molecules, which may be odor molecules and / or moisture molecules. Since the adsorption channel 130 of the fluid treatment device 100 is connected to the adsorption module 110, the adsorption module 110 can adsorb the predetermined molecules from the airflow flowing from the refrigerated compartment 212 into the adsorption channel 130. The treated airflow then flows into the first sub-duct 2411 of the return air duct 241, re-flows into the refrigerated compartment 212, and then flows into the freezer compartment 211 again through the second sub-duct 2412. This effectively treats the airflow within the refrigerated compartment 212 and the freezer compartment 211, such as reducing the content of odor molecules and / or moisture molecules in the airflow within the refrigerated compartment 212 and the freezer compartment 211, thereby achieving odor removal and / or dehumidification. It is understood that the fluid treatment device 100 in this embodiment can be understood as a single-circuit method.

[0110] The fan 290 may be located in the first sub-duct 2411 or the air supply duct 242 or the adsorption duct 130 so that the airflow in the freezing compartment 211, the air supply duct 242, the refrigerating compartment 212, the first sub-duct 2411 and the second sub-duct 2412 forms a circulation path.

[0111] It can be understood that the part of the adsorption module 110 that adsorbs the preset molecules can move to communicate with the desorption channel 140. Thus, under the action of the desorption module 120 and the air supply part 160, the preset molecules are desorbed by utilizing the airflow under preset conditions in the desorption channel 140.

[0112] Furthermore, as shown in Figures 1 and 2, the fresh-keeping device 200 also includes: a box body 220, and a door body 230 for opening and closing the box body 220, a storage compartment 210 is provided in the box body 220, and a fluid processing device 100 is provided on the box body 220 and / or the door body 230, and the fluid processing device 100 is located inside and / or outside the fresh-keeping device 200; wherein, the number of the fluid processing device 100 is at least one.

[0113] Thus, the number of fluid treatment devices 100 can be appropriately set based on the concentration of odor in the storage compartment 210, the efficiency of odor treatment, etc. For example, the number of fluid treatment devices 100 can be one, two, three, or another number. It is understood that when the fresh-keeping device 200 includes multiple storage compartments 210, each storage compartment 210 can be connected to at least one fluid treatment device 100 to directly treat the airflow of each storage compartment 210; or, the multiple storage compartments 210 can include a first portion of storage compartments and a second portion of storage compartments, with the first portion of storage compartments being connected to at least one fluid treatment device 100 to directly treat the airflow of the first portion of storage compartments, and the second portion of storage compartments being in airflow communication with the first portion of storage compartments to indirectly treat the airflow of the second portion of storage compartments.

[0114] The fluid handling device 100 can be installed on the housing 220 or on the door 230, or multiple fluid handling devices 100 can be installed on the housing 220 and the door 230, respectively. The fluid handling device 100 can be located outside or inside the housing 220, or multiple fluid handling devices 100 can be installed inside and outside the housing 220, respectively. This expands the installation range of the gas device.

[0115] In some possible embodiments provided by the present disclosure, the distance between the fluid treatment device 100 and the top wall of the box 220 is 18 cm to 25 cm; the distance between the fluid treatment device 100 and the side wall of the box 220 is 18 cm to 25 cm; the distance between the fluid treatment device 100 and the rear wall of the box 220 is 18 cm to 25 cm.

[0116] By properly setting the distance between the fluid handling device 100 and the top wall, side walls, and rear wall of the refrigerator 220, a reliable connection between the fluid handling device 100 and the storage compartment 210 can be ensured, while minimizing the impact of the fluid handling device 100 on the external dimensions and installation dimensions of the refrigerator. Specifically, the distance between the fluid handling device 100 and the top wall of the refrigerator 220 can be 18 cm, 20 cm, 22 cm, 25 cm, or other dimensions; the distance between the fluid handling device 100 and the side walls of the refrigerator 220 can be 18 cm, 20 cm, 22 cm, 25 cm, or other dimensions; and the distance between the fluid handling device 100 and the rear wall of the refrigerator 220 can be 18 cm, 20 cm, 22 cm, 25 cm, or other dimensions. It should be noted that, in this embodiment, the top wall of the box body 220 refers to the outer top surface of the box body 220, the side wall of the box body 220 refers to the outer wall surface of one side of the box body 220 on which the fluid treatment device 100 is installed, and the rear wall of the box body 220 refers to the outer wall surface of the box body 220 opposite to the door body 230.

[0117] A third aspect of the present disclosure, as shown in FIG7 , provides a control method for a fresh-keeping device, wherein the fresh-keeping device includes the fresh-keeping device of any embodiment of the second aspect, and the control method includes:

[0118] Step S702: controlling the refrigeration module of the fresh-keeping equipment and the desorption module of the fluid processing device to operate simultaneously for at least one working period.

[0119] In this embodiment, because the gases in the adsorption channel 130 and the desorption channel 140 are isolated from each other, the desorption module 120 is separated from the adsorption module 110 and is located away from the adsorption channel 130. This arrangement enables the desorption module 120 to process the airflow in the desorption channel 140 so that the airflow in the desorption channel 140 reaches a predetermined condition. The desorption module 120 has little or no effect on the airflow in the adsorption channel 130. As a result, the adsorption module 110 and the desorption module 120 can operate independently without affecting each other. In other words, the operation of the refrigeration module and the desorption module 120 of the fresh-keeping device 200 do not affect each other. Therefore, the refrigeration module and the desorption module 120 of the fresh-keeping device 200 can be controlled to operate simultaneously for at least one operating period. The adsorption module 110 adsorbs predetermined molecules flowing into the return air channel 241 from the storage compartment 210, while the desorption module 120 simultaneously adjusts the airflow in the desorption channel 140 to a predetermined condition to desorb the predetermined molecules from the adsorption module 110. Compared to the related art in which the refrigeration module and the desorption module cannot operate simultaneously and need to operate at intervals, this arrangement avoids the need for the refrigeration module to stop operating when the desorption module is operating, thereby affecting the cooling effect of the storage compartment 210. The fluid processing device 100 in this embodiment can reasonably control the operating conditions of the refrigeration module according to demand, without being affected by the operating conditions of the desorption module 120, which is conducive to ensuring a good cooling effect for the storage compartment 210. At the same time, because the adsorption channel 130 and the desorption channel 140 are isolated from each other, the airflow flowing out of the desorption channel 140 will not flow into the storage compartment 210, reducing the impact of the airflow in the desorption channel 140 on the airflow in the storage compartment 210, further ensuring a good cooling effect for the airflow in the storage compartment 210.

[0120] Furthermore, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, the control method may also include the following methods and steps.

[0121] The air supply unit 160 and the desorption module 120 of the fluid treatment device 100 are controlled to operate synchronously; the power unit and the desorption module of the fluid treatment device are controlled to operate synchronously.

[0122] Among them, the air supply part 160 and the desorption module 120 of the control fluid treatment device 100 work synchronously, so that when the desorption part works to process the airflow in the desorption channel 140 to meet the preset conditions, the air supply part 160 works to make the airflow that meets the preset conditions flow through the adsorption module 110 and then flow out from the outlet of the desorption channel 140, so as to desorb the preset molecules adsorbed by the adsorption module 110 connected to the desorption channel 140, so as to ensure a good desorption effect.

[0123] Among them, the power unit and the desorption module 120 of the control fluid treatment device 100 work synchronously, and the power unit is used to drive the adsorption module 110 to move relative to the adsorption channel 130 and the desorption channel 140, thereby enabling the part of the adsorption module 110 connected to the adsorption channel 130 and the part connected to the desorption channel 140 to be alternately exchanged. In this way, when the desorption module 120 is working, the desorption treatment of different parts of the adsorption module 110 can be realized in turn, thereby making the entire adsorption module 110 gradually restore its adsorption capacity over and over again, that is, realizing the regeneration adsorption capacity of the adsorption module 110, further extending the adsorption time and adsorption capacity of the adsorption module 110, avoiding the step of replacing the adsorption module 110, and helping to save usage costs.

[0124] It is understood that in some embodiments, the air supply unit 160 is opened for a preset time period relative to the desorption module 120, wherein the preset time period can be 30s to 300s, such as 30s, 60s, 120s, 300s, or other time periods. In this way, it is ensured that the air supply unit 160 will not start working until the desorption module 120 processes the air flow in the desorption channel 140 to meet the preset conditions, ensuring that the air flow in the desorption channel 140 flowing through the adsorption module 110 meets the preset conditions, thereby ensuring a good desorption effect. It is understood that in this case, the air supply unit 160 and the desorption module 120 can be controlled to stop working at the same time.

[0125] Furthermore, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, the control method may also include the following methods and steps.

[0126] Based on the adsorption capacity of the adsorption module connected to the adsorption channel meeting the first preset condition, the desorption module is controlled to start working.

[0127] Among them, when the adsorption capacity of the adsorption module 110 connected to the adsorption channel 130 meets the first preset condition, it means that the adsorption capacity of the adsorption module 110 connected to the adsorption channel 130 is low, and there is a situation where the adsorption capacity is insufficient, close to saturation or saturated, and the preset molecules cannot be effectively adsorbed. At this time, the desorption module 120 can be controlled to work. It can be understood that the power unit and the air supply unit 160 can be controlled to work synchronously to rotate the part of the adsorption module 110 connected to the adsorption channel 130 to connect to the desorption channel 140, and use the desorption module 120 to process the airflow in the desorption channel 140 to the preset conditions to achieve adsorption processing of the adsorption module 110, so as to improve the adsorption capacity of this part of the adsorption module 110, thereby ensuring that the entire adsorption module 110 has good adsorption capacity.

[0128] Furthermore, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, the control method may also include the following methods and steps.

[0129] Based on the adsorption capacity of the adsorption module 110 connected to the adsorption channel 130 meeting the second preset condition within the first preset time period, the desorption module 120 is controlled to stop working.

[0130] When the adsorption capacity of the adsorption module 110 connected to the adsorption channel 130 meets the second preset condition within the first preset time period, it indicates that the adsorption capacity of the adsorption module 110 connected to the adsorption channel 130 has been good for a certain period of time. It can be understood that the adsorption capacity of the adsorption module 110 that meets the second preset condition is greater than the adsorption capacity of the adsorption module 110 that meets the first preset condition. At this time, the desorption module 120 can be controlled to stop working to save energy.

[0131] The first preset time length may be 10s to 300s. Specifically, the first preset time length may be 10s, 30s, 60s, 120s, 300s, or other time lengths.

[0132] For example, if the adsorption capacity of the adsorption module 110 connected to the adsorption channel 130 meets the second preset condition within 60 seconds, it indicates that the adsorption module 110 connected to the adsorption channel 130 has good adsorption capacity. At this time, the airflow in the adsorption channel 130 contains fewer preset molecules, and the adsorption module 110 cannot reach saturation for a long time. In this case, the desorption module 120 can be controlled to stop working to save energy.

[0133] Furthermore, as a refinement and extension of the specific implementation of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, the control method may also include the following methods and steps.

[0134] Based on the operating time of the desorption module 120 reaching the second preset time, the desorption module 120 is controlled to stop operating.

[0135] The second preset duration is set to ensure that the entire adsorption module 110 has good adsorption capacity. This means that the adsorption module 110 may require a long time to reach saturation. In this case, the desorption module 120 can be controlled to stop operating to save energy. Specifically, the second preset duration can be 600s to 6000s. Specifically, the second preset duration can be 600s, 1000s, 2000s, 3000s, 6000s, or another duration.
