However, it is obvious to those skilled in the art that the technical solutions provided by the present disclosure can be implemented without one or more of these details.

[0046] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of the features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0047] Now, exemplary embodiments according to the present disclosure will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present disclosure thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0048] like Figures 1 to 7 As shown, the embodiment of the present disclosure provides 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, and the fresh-keeping device 200 can be a refrigerator, a cold chain transport vehicle, etc.

[0049] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of the first aspect of the present disclosure provides a fluid processing device 100, which is used for a fresh-keeping device 200. The fluid processing device 100 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 is connected to a storage compartment 210 of the fresh-keeping device 200 and the adsorption module 110. The return air channel 241 is connected to 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 channel 130 and the desorption channel 140 are connected, the adsorption module 110 is used to remove preset molecules in the airflow flowing through it, that is, to adsorb the preset molecules on the adsorption module 110, and the desorption module 120 is used to make the airflow in the desorption channel 140 be in preset conditions to desorb the preset molecules in the adsorption module 110, that is, to desorb the preset molecules from the adsorption module 110; wherein, the adsorption channel 130 and the desorption channel 140 are isolated from each other, 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.

[0050] The preservation device 200 includes a storage compartment 210 for accommodating objects to be preserved, and the preservation device 200 also includes a refrigeration module. The storage compartment 210 is connected to an air supply channel 242 and an air return channel 241. The air supply channel 242 is used to introduce dry cold airflow passing through the refrigeration module into the storage compartment 210, and the air return channel 241 is used to guide the airflow flowing out of the storage compartment 210 to flow through the refrigeration module. Thus, the airflow in the storage compartment 210 and the airflow flowing through the refrigeration module form a circulating airflow path under the guidance of the air supply channel 242 and the air return channel 241, so that the airflow in the storage compartment 210 can be kept in a low temperature state for a long time, so as to utilize the low temperature to reduce the activity of microorganisms and enzymes, slow down the respiration of food and microorganisms, and prolong the shelf life.

[0051] 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. The adsorption channel 130 is as follows: Figures 3 to 5As shown in , the airflow flowing out of the storage compartment 210 of the fresh-keeping device 200 passes through the adsorption channel 130 and then flows through the adsorption module 110, and then is sent back to the storage compartment 210 through the return air channel 241. Therefore, the odor generated by the oxidation and decomposition of the objects to be preserved in the storage compartment 210 enters the adsorption module 110 after passing through the adsorption channel 130. The adsorption module 110 can remove the preset molecules in the airflow flowing through the adsorption module 110, wherein the preset molecules can be odor molecules, that is, the adsorption module 110 has the function of removing odor. In addition, the airflow flowing back to the refrigeration module through the return air channel 241 is relatively fresh, and the odor of the dry cold airflow flowing into the storage compartment 210 again through the air supply channel 242 is reduced, so that the airflow in the storage compartment 210 is relatively fresh, the influence of the odor on the objects to be preserved is reduced, and the user experience is improved. After multiple cycles of the airflow, the odor will be gradually reduced or even eliminated.

[0052] It is understandable that the preset molecules may also include water molecules, so the adsorption module 110 may also be a moisture absorption module to reduce the humidity of the airflow in the storage compartment 210, extend the preservation time of the objects to be preserved, and help reduce the generation of odor in the storage compartment 210. Specifically, the preset molecules may include odor molecules and water molecules.

[0053] The adsorption module 110 is connected to the desorption channel 140 and the adsorption channel 130. The desorption channel 140 can be Figures 3 to 5 As shown by the dotted lines in , the desorption module 120 is used to make the airflow in the desorption channel 140 under preset conditions to desorb the preset molecules adsorbed by the adsorption module 110. Thus, the desorption module 120 can be used to desorb the preset molecules in the adsorption module 110 connected to the desorption channel 140, and restore the adsorption capacity of the adsorption module 110. Thus, the adsorption time of the adsorption module 110 is extended, and the adsorption capacity of the adsorption module 110 is improved, thereby avoiding the adsorption module 110 losing its adsorption capacity after adsorption saturation and affecting the deodorization effect, or the need to replace the adsorption module 110 with a new one, which is costly. That is to say, 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.

[0054] The preset conditions may be desorption temperature and / or desorption pressure, etc. For example, the desorption module 120 may make the airflow in the desorption channel 140 at a preset desorption temperature so that the preset molecules in the adsorption module 110 are desorbed. In this case, the desorption module 120 may be a structure with heating capability. And / or, the desorption module 120 may make the airflow in the desorption channel 140 at a preset desorption pressure so that the preset molecules in the adsorption module 110 are desorbed. In this case, the desorption module 120 may be a pressure regulating structure.

[0055] 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 / or the desorption module 120 is far away from the adsorption channel 130. Such a configuration 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 preset condition, and the desorption module 120 has little or no effect on the airflow in 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 work simultaneously for at least one working time, and the adsorption module 110 is used to adsorb the preset molecules flowing into the adsorption channel 130 from the storage compartment 210, and at the same time, the desorption module 120 is used to make the airflow in the desorption channel 140 reach the preset condition to perform desorption processing on the preset molecules in the adsorption module 110. Compared with the configuration in which the refrigeration module and the desorption module cannot work at the same time, that is, they need to work at intervals, such a 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 .

[0056] The fluid treatment device 100 in this embodiment can reasonably control the working condition of the refrigeration module according to the demand, without being affected by the working condition of the desorption module 120, which is conducive to ensuring a good refrigeration effect of the storage compartment 210. At the same time, since 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, thereby reducing the influence of the airflow in the desorption channel 140 on the airflow in the storage compartment 210, further ensuring a good refrigeration effect of the airflow in the storage compartment 210, that is, even in the process of the desorption module 120 desorbing the preset molecules in the adsorption module 110, the refrigeration module can continue to work to ensure a good refrigeration effect of the storage compartment 210.

[0057] 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 .

[0058] The desorption module 120 can be connected to the inner wall or outer wall of the desorption channel 140, or connected to the inner wall and outer wall of the adsorption channel 130 at the same time, or connected to the outer wall of the adsorption module 110. Thus, the desorption module 120 works, and the airflow in the desorption channel 140 can quickly 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 restores good adsorption capacity. At the same time, this setting can reduce the influence of the desorption module 120 on the airflow in the adsorption channel 130.

[0059] It is understandable that in order to reduce the influence 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 .

[0060] 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 may be connected to the shell. For example, the desorption module 120 may be arranged 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 that the gas in the adsorption channel 130 and the desorption channel 140 enters the shell and moves and mixes; and reducing or eliminating the phenomenon that the gas in the first space and the second space moves and mixes with each other.

[0061] Among them, the desorption module 120 is connected to the outside of the shell, which is convenient for the disassembly and assembly of the desorption module 120 and the shell. The desorption module 120 can be directly repaired and replaced on the outside of the shell, which is easy to operate. Compared with the desorption module 120 installed inside the shell and the need to disassemble the shell to repair and replace the desorption module 120, it is conducive to improving the efficiency of maintenance and replacement. At the same time, the desorption module 120 is connected to the outside of the shell corresponding to the desorption channel 140. Therefore, by working with the desorption module 120, the airflow in the desorption channel 140 can quickly 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 restores 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 work at the same time, that is, the refrigeration module and the desorption module 120 of the fresh-keeping device 200 can operate at the same time at least for a 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.

[0062] In some possible embodiments provided by the present disclosure, the fluid treatment device 100 further includes a power unit, which drives the adsorption module to move relative to the adsorption channel 130 and the desorption channel 140 .

[0063] Thus, by using the power unit, different parts of the adsorption module 110 can be alternately connected to the adsorption channel 130 and the desorption channel 140. Since the adsorption module 110 connected to the adsorption channel 130 can adsorb the preset molecules in the adsorption channel 130, at the same time, the adsorption module 110 connected to the desorption channel 140 can desorb the preset molecules under the action of the airflow in the desorption channel 140 under the preset conditions so that the adsorption module 110 in this area can restore the adsorption capacity. Thus, in the process of the power unit driving the adsorption module 110 to move relative to the adsorption channel 130 and the desorption channel 140, the preset molecules in the adsorption channel 130 can be adsorbed by different parts of the adsorption module 110 in turn, and the desorption module 120 can desorb different parts of the adsorption module 110 in turn to restore its adsorption capacity, thereby making the entire adsorption module 110 gradually restore its adsorption capacity over and over again, that is, the adsorption capacity regeneration of the adsorption module 110 is achieved, the adsorption time and adsorption capacity of the adsorption module 110 are further extended, and the step of replacing the adsorption module 110 is avoided, which is conducive to saving the use cost.

[0064] Specifically, the power unit can be a driving motor (i.e., an electric drive), a pneumatic drive, a hydraulic drive, etc. Among them, the adsorption module 110 is a turntable, preferably a circular turntable. The power unit is connected to the turntable driving device 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 rotates to connect with 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 until it is connected to the adsorption channel 130, it has a good ability to adsorb the preset molecules, avoiding the situation where the adsorption capacity of this part of the turntable is saturated and cannot adsorb the preset molecules.

[0065] 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 respectively connected to the adsorption channel 130 and the return air channel 241, and the second space is connected to the desorption channel. The setting 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.

[0066] 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 between the first space and the second space. In some other embodiments, there is good sealing between the turntable and the partition to block the intercommunication of the gas between 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 enter the shell and are separated and kept relatively sealed. 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 passes through the partition as little as possible to reach the adsorption channel 130.

[0067] 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. Preferably, 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.

[0068] like Figures 3 to 5 As shown, 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 to the adsorption module 110 through the desorption module 120 to drive the air flow to circulate between the air supply unit 160, the desorption module 120 and the adsorption module 110.

[0069] Thus, after 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 working, the airflow meeting the preset conditions can flow through the adsorption module 110 to desorb the preset molecules adsorbed by the adsorption module 110, thereby ensuring a good desorption effect. The air supply unit 160 may be a fan.

[0070] In some possible embodiments provided by the present disclosure, the adsorption module 110 includes a moisture-absorbing material and / or a deodorizing material.

[0071] Among them, the hygroscopic material parts can 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.), polymer hygroscopic agent, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina and other materials with hygroscopic properties. Among them, polymer hygroscopic agent is also called polymer adsorbent, which has a lower regeneration temperature than traditional silica gel, activated carbon and molecular sieve adsorbents.

[0072] 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.

[0073] In one embodiment, the adsorption module 110 may be a moisture absorption and dehumidification rotating disk or a deodorization rotating disk, which may be made of porous materials such as zeolite, molecular sieve, metal organic framework (MOF) material, covalent organic framework (COFs), nanocarbon, silicon dioxide, etc. In one embodiment, the moisture absorption and dehumidification rotating disk or the deodorization rotating disk may also be formed by filling granular solids or particles made of at least one of the above-mentioned porous materials.

[0074] 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 a deodorizer, which can adsorb and desorb / desorb absorbed water vapor or odor to achieve repeated desorption and regeneration.

[0075] In one embodiment, the moisture absorption and dehumidification rotating disk or the deodorization rotating disk includes an inorganic / organic fiber carrier (such as ceramic, glass fiber, MOFs, COFs, cordierite, etc.), and the fiber carrier is coated with a moisture absorbent or deodorant such as a molecular sieve, and the molecular sieve is evenly distributed between the fiber carriers and on the surface of the fiber carrier to achieve the adsorption of airflow moisture or odor. The molecular sieve may include single crystal molecular sieves or mixed crystal molecular sieves such as A-type molecular sieves, X / Y-type molecular sieves, ZSM molecular sieves, and Beta molecular sieves.

[0076] 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.

[0077] That is, the desorption module 120 is a heating structure, and the desorption module 120 is used to make the airflow in the desorption channel 140 at a preset temperature to desorb the preset molecules in the adsorption module 110, and the preset temperature can be the desorption temperature of the adsorption module 110. Among them, the desorption module 120 can be any one, any two, or all of a heater, an ultrasonic generator, and a microwave generator. It can be understood that the heat of the desorption module can also come from resistance heating, waste heat conducted by a heat pipe, or heat dissipation by a condenser, etc.

[0078] like Figures 3 to 5 As shown, 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 of the first branch of the desorption channel 140 and the outlet of the second branch 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. Preferably, 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 to the adsorption module 110 through the desorption module 120, and then discharges it into the environment through the second branch of the desorption channel 140.

[0079] In this embodiment, the desorption channel 140 and the external environment form an air circulation path, so that the desorption channel 140 and the adsorption channel 130 are independent of each other. Specifically, the airflow of the external environment flows to the desorption module 120 through the inlet of the first branch of the desorption channel 140, and after being processed by the desorption module 120 to reach the preset conditions, it passes through the adsorption module 110 connected to the desorption channel 140, and after desorbing the preset molecules adsorbed by the adsorption module 110, it flows to the external environment from the outlet of the second branch of the desorption channel 140, that is, the airflow flowing out of the desorption channel 140 will not circulate, and will not return to the storage compartment 210, thereby reducing 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.

[0080] 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 passing through it.

[0081] 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.

[0082] In this embodiment, the desorption channel 140, the external environment and the digestion module form a closed airflow passage, so that the desorption channel 140 and the adsorption channel 130 are independent of each other. Specifically, the airflow of the external environment flows to the desorption module 120 through the inlet of the first branch of the desorption channel 140, and after being processed by the desorption module 120 to reach the preset conditions, the preset molecules adsorbed by the adsorption module 110 are desorbed, and then flow to the digestion module from the outlet of the second branch of the desorption channel 140, and after being digested by the digestion module, the airflow is directly discharged to the external environment instead of being discharged through the outlet of the second branch of the desorption channel 140, thereby reducing the impact of the airflow discharged through the second branch of the desorption channel 140 on the external environment.

[0083] 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 will be processed by the desorption module 120 to reach the preset conditions, and when the air supply unit 160 is working, the airflow reaching the preset conditions can flow through the adsorption module 110 to desorb the preset molecules adsorbed by the adsorption module 110, and the airflow flowing through the adsorption module 110 flows into the digestion module, and after being digested by the digestion module, it is blown to the desorption module 120 again through the air supply unit 160 to enter the next cycle.

[0084] Among them, the digestion method of the digestion module can be to use catalysts, enzymes, ultraviolet rays, electrolysis, thermal decomposition or chemical digestion products 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 of the airflow discharged from the outlet of the desorption channel 140, wherein 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.

[0085] 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.

[0086] 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 the pollution 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.

[0087] Specifically, the airflow from the external environment flows to the desorption module 120 through the first branch of the desorption channel 140, desorbs the preset molecules adsorbed by the adsorption module 110 after being processed by the desorption module 120 to reach the preset conditions, and then 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.

[0088] 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 reach the preset conditions. When the air supply unit 160 is working, the airflow reaching 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 blows 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 interchanged.

[0089] like Figures 1 to 5 As shown, the embodiment of the second aspect of the present disclosure provides a fresh-keeping device 200, including: a storage compartment 210, and a fluid processing device 100 of any embodiment of the first aspect. Since the fresh-keeping device 200 includes the fluid processing device 100 of any embodiment of the first aspect, it has all the beneficial technical effects of the above-mentioned fluid processing device 100, which will not be repeated here one by one.

[0090] like Figures 3 to 5As shown, 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 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, and 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 within at least one working period.

[0091] Therefore, the working condition of the refrigeration module can be reasonably controlled according to the demand without being affected by the working condition of the desorption module 120, which is conducive to ensuring a good refrigeration effect of the storage compartment 210. At the same time, since the airflows in the adsorption channel 130 and the desorption channel 140 are isolated from each other, the airflow out of the desorption channel 140 will not flow into the storage compartment 210 or will flow into a very small amount, reducing the influence of the airflow in the desorption channel 140 on the airflow in the storage compartment 210, further ensuring a good refrigeration effect of the airflow in the storage compartment 210.

[0092] like Figures 3 to 5 As shown, 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.

[0093] The evaporator 270 is located in the freezing chamber 211 to achieve refrigeration of the freezing chamber 211. Specifically, the control device controls the compressor 280 of the refrigeration module to work, so that the refrigerant flows between 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, thereby reducing the temperature of the freezing chamber 211 and achieving refrigeration of the freezing chamber 211.

[0094] It is understandable that, when the storage compartment 210 also includes other compartments, the evaporator 270 may also be located in the other storage compartments 210 to cool the corresponding storage compartments 210, or, the evaporator 270 in the freezer compartment 211 may be used alone to indirectly cool the other storage compartments 210 through the air supply channel 242.

[0095] like Figure 3As shown, 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.

[0096] In this embodiment, the storage compartment 210 of the fresh-keeping device 200 includes a freezing compartment 211 and a refrigerating compartment 212. Since the air supply channel 242 is connected to the first air outlet of the freezing compartment 211 and the second air inlet of the refrigerating compartment 212, the adsorption channel 130 is connected to the second air outlet of the refrigerating compartment 212 and the adsorption module 110, and the return air channel 241 is connected to the adsorption module 110 and the first air inlet of the freezing compartment 211, under the action of the fan 290, the dry cold air near the evaporator 270 flows from the freezing compartment 211 to the refrigerating compartment 212 through the air supply channel 242, and the air flow in the refrigerating compartment 212 flows to the adsorption module 110 through the adsorption channel 130, and finally flows back into the freezing compartment 211 through the return air channel 241, thereby realizing the circulation of the air flow, and adsorbing the preset molecules in the air flow in the adsorption module 110.

[0097] The evaporator 270 of the refrigeration module is located in the freezing compartment 211, so that the airflow temperature in the freezing compartment 211 is relatively low, thereby realizing the refrigeration function of the freezing compartment 211. The dry cold airflow near the evaporator 270 flows through the freezing compartment 211 and the air supply channel 242 to the refrigerating compartment 212 under the action of the fan 290, thereby realizing the refrigeration function of the refrigerating compartment 212. Among them, the airflow flowing from the cold storage compartment 212 into the return air channel 241 will carry preset molecules, which can be odor molecules and / or moisture molecules, etc. Since the adsorption channel 130 of the fluid treatment device 100 is connected to the adsorption module 110, the airflow flowing out of the cold storage compartment 212 can be sent to the adsorption module 110 through the adsorption channel 130, and the preset molecules in the airflow are adsorbed in the adsorption module 110. Then, the treated airflow flows into the return air channel 241 and flows into the freezing compartment 211 again, and flows into the cold storage compartment 212 again through the air supply channel 242, thereby achieving the treatment of the airflow in the freezing compartment 211 and the cold storage compartment 212, such as reducing the content of odor molecules and / or moisture molecules in the airflow in the freezing compartment 211 and the cold storage compartment 212, and achieving the effect of removing odor and / or dehumidification. It can be understood that the fluid treatment device 100 in this embodiment can be understood as a single cycle mode, and the fresh-keeping device 200 in this embodiment is air-cooled refrigeration.

[0098] The fan 290 may 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 refrigerating compartment 212, the adsorption channel 130, the adsorption module 110, and the return air channel 241 forms a circulation path.

[0099] It is understandable that, under the action of the power unit, the part of the adsorption module 110 adsorbing the preset molecules can move to communicate with the desorption channel 140, thereby, under the action of the desorption module 120 and the air supply unit 160, the preset molecules adsorbed in the adsorption module 110 are desorbed by the airflow in the desorption channel 140 under the preset conditions. Figure 4 As shown, in some possible embodiments provided by the present disclosure, the storage compartment 210 also includes a variable temperature compartment 213, and the variable temperature compartment 213 is provided with a third air inlet and a third air outlet. The third air inlet is connected to the air supply channel 242 through a pipeline, and the third air outlet is connected to the adsorption module 110 of the fluid treatment device 100 through the adsorption channel 130.

[0100] In this embodiment, the storage compartment 210 of the fresh-keeping device 200 includes a freezing compartment 211, a refrigerating compartment 212 and a temperature-variable compartment 213. Since the air supply channel 242 is connected to the first air outlet of the freezing compartment 211 and the second air inlet of the refrigerating compartment 212, the third air inlet of the temperature-variable compartment 213 is connected to the air supply channel 242 through a pipeline, the third air outlet of the temperature-variable 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 is connected to the adsorption module 110 and the first air inlet of the freezing compartment 211. Therefore, under the action of the fan 290, the dry cold air near the evaporator 270 flows through the freezing chamber 211 from the air supply channel 242 to the refrigerating chamber 212 and the temperature-changing chamber 213, and the air in the refrigerating chamber 212 and the temperature-changing chamber 213 flows into the adsorption module 110 through the adsorption channel 130, and then flows back into the freezing chamber 211 through the return air channel 241, thereby realizing the circulation of air flow.

[0101] The evaporator 270 of the refrigeration module is located in the freezing compartment 211, so that the airflow temperature in the freezing compartment 211 is relatively low, thereby realizing the refrigeration function of the freezing compartment 211. The dry cold airflow near the evaporator 270 flows through the freezing compartment 211 through the air supply channel 242 to the refrigerating compartment 212 and the temperature-changing compartment 213 under the action of the fan 290, thereby realizing the refrigeration function of the refrigerating compartment 212 and the temperature-changing compartment 213. The airflow flowing from the refrigerating compartment 212 and the temperature-changing compartment 213 into the adsorption channel 130 and the airflow flowing from the temperature-changing compartment 213 into the adsorption channel 130 will carry preset 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 preset molecules in the airflow flowing from the refrigerating compartment 212 and the temperature-changing compartment 213 into the adsorption channel 130 can be adsorbed. Then, the treated airflow flows into the return air channel 241 and flows into the freezing compartment 211 again, and flows into the refrigerating compartment 212 and the temperature-changing compartment 213 again through the air supply channel 242. Thus, the airflow in the freezing compartment 211, the refrigerating compartment 212, and the temperature-changing compartment 213 is processed, such as reducing the content of odor molecules and / or moisture molecules in the airflow in the freezing compartment 211, the refrigerating compartment 212, and the temperature-changing compartment 213, thereby achieving the effect of removing odor 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.

[0102] The fan 290 may be located in the return air passage 241 or in the supply air passage 242, so that the airflow in the freezing chamber 211, the supply air passage 242, the refrigerating chamber 212 / the temperature-changing chamber 213, the adsorption passage 130, the adsorption module 110, and the return air passage 241 forms a circulation passage. It is understandable that the compressor 280 and the fan 290 may work synchronously.

[0103] It is understandable that the part of the adsorption module 110 adsorbing the preset molecules can move to communicate with the desorption channel 140, thereby, under the action of the desorption module 120 and the air supply unit 160, the preset molecules are desorbed by the airflow under preset conditions in the desorption channel 140.

[0104] like Figure 5As shown, 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 inlet 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.

[0105] 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 handling device 100 connects the second air outlet and the adsorption module 110 of the fluid handling device 100, the first sub-air channel 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-air channel 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 the fan 290, the dry cold air near the evaporator 270 flows through the freezing chamber 211 and the air supply channel 242 to the refrigerating chamber 212, and the air in the refrigerating chamber 212 flows into the adsorption module 110 through the adsorption channel 130, and then flows into the refrigerating chamber 212 again through the first sub-air channel 2411 of the return air channel 241, and returns to the freezing chamber 211 through the second sub-air channel 2412 of the return air channel 241, thereby realizing the circulation of air flow. It can be understood that this kind of fresh-keeping device 200 can be understood as a direct cooling refrigeration method.

[0106] The evaporator 270 of the refrigeration module is located in the freezing compartment 211, so that the airflow temperature in the freezing compartment 211 is relatively low, thereby realizing the refrigeration function of the freezing compartment 211. The dry cold airflow near the evaporator 270 flows through the freezing compartment 211 and the air supply channel 242 to the refrigerating compartment 212 under the action of the fan 290, thereby realizing the refrigeration function of the refrigerating compartment 212. Among them, the airflow flowing from the refrigerating compartment 212 into the adsorption channel 130 will carry preset molecules, which can 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 preset molecules in the airflow flowing from the refrigerating compartment 212 into the adsorption channel 130. Then, the treated airflow flows into the first sub-air duct 2411 of the return air duct 241 and flows back into the refrigerating compartment 212, and flows into the freezing compartment 211 again through the second sub-air duct 2412, thereby achieving the treatment of the airflow in the refrigerating compartment 212 and the freezing compartment 211, such as being able to reduce the content of odor molecules and / or moisture molecules in the airflow in the refrigerating compartment 212 and the freezing compartment 211, and achieving the effect of removing odor and / or dehumidification. It can be understood that the fluid treatment device 100 in this embodiment can be understood as a single-cycle mode.

[0107] Among them, the fan 290 can 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 passage.

[0108] It is understandable that the part of the adsorption module 110 adsorbing the preset molecules can move to communicate with the desorption channel 140, thereby, under the action of the desorption module 120 and the air supply unit 160, the preset molecules are desorbed by the airflow under preset conditions in the desorption channel 140.

[0109] Furthermore, if Figure 1 and Figure 2 As shown, 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 arranged in the box body 220, a fluid handling device 100 is arranged on the box body 220 and / or the door body 230, and the fluid handling device 100 is located inside and / or outside the fresh-keeping device 200; wherein, the number of the fluid handling device 100 is at least one.

[0110] Therefore, the number of fluid treatment devices 100 can be reasonably set according to the concentration of odor in the storage compartment 210, the efficiency of odor treatment, etc., such as the number of fluid treatment devices 100 can be one, two, three or other numbers. It can be 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 achieve direct treatment of the airflow of each storage compartment 210; or, the multiple storage compartments 210 include a first part of storage compartments and a second part of storage compartments, the first part of the storage compartments are connected to at least one fluid treatment device 100 to achieve direct treatment of the airflow of the first part of the storage compartments, and the second part of the storage compartments are connected to the first part of the storage compartments to achieve indirect treatment of the airflow of the second part of the storage compartments.

[0111] The fluid treatment device 100 may be arranged on the box body 220 or on the door body 230, or a plurality of fluid treatment devices 100 may be arranged on the box body 220 and on the door body 230, respectively. The fluid treatment device 100 may be located outside the box body 220 or inside the box body 220, or a plurality of fluid treatment devices 100 may be arranged inside and outside the box body 220, respectively. Thus, the setting range of the gas device is expanded.

[0112] 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.

[0113] Among them, by reasonably setting the distance between the fluid handling device 100 and the top wall of the box 220, the side wall of the box 220, and the rear wall of the box 220, it is possible to ensure that the fluid handling device 100 is reliably connected to the storage compartment 210, and at the same time, it is possible to minimize 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 box 220 can be 18cm, 20cm, 22cm, 25cm, or other sizes; the distance between the fluid handling device 100 and the side wall of the box 220 is 18cm, 20cm, 22cm, 25cm, or other sizes; the distance between the fluid handling device 100 and the rear wall of the box 220 is 18cm, 20cm, 22cm, 25cm, or other sizes.

[0114] The third aspect of the present disclosure is as follows Figure 7 As shown, a control method for a fresh-keeping device is provided, the fresh-keeping device includes the fresh-keeping device of any embodiment of the second aspect, and the control method includes:

[0115] Step S702: Control the refrigeration module of the fresh-keeping equipment and the desorption module of the fluid processing device to operate simultaneously within at least one working time.

[0116] In this embodiment, since 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 the desorption module 120 is arranged far away from the adsorption channel 130. Such an 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 preset condition, and the desorption module 120 has little or no effect on the airflow in the adsorption channel 130. Therefore, the adsorption module 110 and the desorption module 120 can work independently without affecting each other, that is, 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 work simultaneously for at least one working time, and the adsorption module 110 is used to adsorb the preset molecules flowing into the return air channel 241 from the storage compartment 210, and at the same time, the desorption module 120 is used to make the airflow in the desorption channel 140 reach the preset condition to desorb the preset molecules in the adsorption module 110. Compared with the related art in which the refrigeration module and the desorption module cannot work at the same time and need to work at intervals, such a setting avoids the need for the refrigeration module to stop working when the desorption module is working to affect the refrigeration effect of the storage compartment 210. The fluid treatment device 100 in this embodiment can reasonably control the working condition of the refrigeration module according to demand, without being affected by the working condition of the desorption module 120, which is conducive to ensuring a good refrigeration effect of the storage compartment 210. At the same time, since the adsorption channel 130 and the desorption channel 140 are isolated from each other, the airflow out of the desorption channel 140 will not flow into the storage compartment 210, reducing the influence of the airflow in the desorption channel 140 on the airflow in the storage compartment 210, further ensuring a good refrigeration effect of the airflow in the storage compartment 210.

[0117] 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.

[0118] The air supply unit 160 and the desorption module 120 of the fluid treatment device 100 are controlled to work synchronously; the power unit and the desorption module of the fluid treatment device are controlled to work synchronously.

[0119] 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 reach the preset conditions, the air supply part 160 works to make the airflow reaching 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.

[0120] 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, the part of the adsorption module 110 connected with the adsorption channel 130 and the part connected with the desorption channel 140 can 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, so that the adsorption capacity of the entire adsorption module 110 is gradually restored over and over again, that is, the regeneration adsorption capacity of the adsorption module 110 is realized, the adsorption time and adsorption capacity of the adsorption module 110 are further extended, and the step of replacing the adsorption module 110 is avoided, which is conducive to saving the use cost.

[0121] It is understood that in some embodiments, the air supply unit 160 is opened for a preset time relative to the desorption module 120, wherein the preset time may be 30s to 300s, such as 30s, 60s, 120s, 300s or other time, thereby ensuring that the air supply unit 160 starts working only after the desorption module 120 processes the airflow in the desorption channel 140 to meet the preset conditions, ensuring that the airflow in the desorption channel 140 flowing through the adsorption module 110 is the airflow that meets the preset conditions, so as to ensure 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.

[0122] 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.

[0123] 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.

[0124] 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 be connected to the desorption channel 140, and the desorption module 120 is used to process the airflow in the desorption channel 140 to the preset condition to realize the adsorption treatment 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.

[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 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.

[0127] Among them, 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, it means that the adsorption module 110 connected to the adsorption channel 130 has good adsorption capacity within 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 consumption.

[0128] 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.

[0129] For example, when the adsorption capacity of the adsorption module 110 connected to the adsorption channel 130 meets the second preset condition within 60 seconds, it means that the adsorption module 110 connected to the adsorption channel 130 has good adsorption capacity. At this time, the preset molecules of the airflow in the adsorption channel 130 are small, and the adsorption module 110 cannot reach the saturation state for a long time. At this time, the desorption module 120 can be controlled to stop working to save energy consumption.

[0130] 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.

[0131] Based on the working time of the desorption module 120 reaching the second preset time, the desorption module 120 is controlled to stop working.

[0132] Among them, the setting of the second preset time can ensure that the entire adsorption module 110 has a good adsorption capacity, that is, the adsorption module 110 may work for a long time to reach a saturated state. At this time, the desorption module 120 can be controlled to stop working to save energy. Specifically, the second preset time can be 600s to 6000s, specifically, the second preset time can be 600s, 1000s, 2000s, 3000s, 6000s or other time.
