[0046] Further, as shown in Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 and Figure 11 , the present embodiment provides a drying system, which comprises a containing cavity 102 containing objects to be dried, a suction assembly, and a drying module. The drying module comprises a first heating part 4 and an adsorption part 6, and the suction assembly is arranged between the containing cavity 102 and the drying module.

[0047] The object drying system provided in the present application can be applied to a washing device (such as a washing and drying integrated machine, a clothes treatment device, a household appliance, a dishwasher, etc.).

[0048] In some embodiments, the containing cavity 102, the door sealing assembly 101, the air inlet 1011, the air outlet 1021, and the containing cavity 102 constitute a containing assembly 1. The containing cavity 102 is in communication with the air inlet 1011 and the air outlet 1021, respectively. The containing cavity 102 is further provided with an opening for placing objects to be dried and taking out dried objects. The door sealing assembly 101 can be used to close the opening.

[0049] Further, the air outlet 1011 is provided with a filtering part 7. The filtering part 7 can filter impurities carried by the airflow at the air outlet 1011, thereby improving the cleanliness of the airflow to avoid damage to the components in the drying process. The filtering part 7 can use existing filtering devices such as a filter screen, etc., which is not strictly limited here.

[0050] The adsorption part 6 includes a granular molecular sieve, a honeycomb molecular sieve, or an adsorption block, and the like, and is made of a material having a moisture adsorption and desorption performance. The adsorption part 6 has a good moisture adsorption effect.

[0051] In an embodiment, the adsorption part 6 can be provided with a moisture adsorbent for absorbing moisture. The moisture adsorbent can be, for example, a zeolite, a modified / synthetic zeolite, a molecular sieve (including but not limited to a zeolite molecular sieve, an A / X / Y type molecular sieve, a ZSM molecular sieve, a Beta molecular sieve, and the like), a high-molecular moisture adsorbent, an alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, and the like, which have a moisture adsorption performance. Among them, the high-molecular moisture adsorbent, also known as a polymer adsorbent, has a lower regeneration temperature than traditional silica gel, activated carbon, and molecular sieve adsorbents.

[0052] In an embodiment, the adsorption part 6 can be made of a porous material such as a zeolite, a molecular sieve, a metal organic framework (MOF) material, a covalent organic framework material (COF), nano-carbon, and silicon dioxide. In an embodiment, the adsorption part 6 can also be filled with a granular solid or a particle made of at least one of the above-mentioned porous materials.

[0053] In an embodiment, the adsorption part 6 can be a honeycomb or corrugated rotating disc loaded with a moisture adsorbent, which can adsorb and desorb the absorbed water vapor to realize repeated desorption and regeneration.

[0054] In an embodiment, the adsorption part 6 includes an inorganic / organic fiber carrier (such as ceramic, glass fiber, MOF, COF, cordierite, and the like), and a molecular sieve or the like moisture adsorbent is coated on the fiber carrier. The molecular sieve is uniformly distributed between the fiber carriers and on the surface of the fiber carrier to realize adsorption of the moisture in the airflow. The molecular sieve can include a single-crystal molecular sieve such as an A type molecular sieve, an X / Y type molecular sieve, a ZSM molecular sieve, a Beta molecular sieve, or a mixed-crystal molecular sieve.

[0055] In the embodiment, the first heating part 4 and the adsorption part 6 are used to dry the object to be dried, thereby reducing the water content of the object and improving the drying effect, which can meet the needs of users.

[0056] Further, the drying system further includes a controller, which can be implemented by using various application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), micro control elements, microprocessors, or other electronic elements.

[0057] Specifically, the controller is configured to control the first heating unit 4 and the suction assembly to work, so that the airflow sucked by the suction assembly passes through the first heating unit 4 and then passes through the adsorption unit 6 to perform the first drying process.

[0058] In a specific application, the drying process of the object to be dried can be started by the drying instruction. The drying instruction can be automatically generated after the object is cleaned, for example, the drying instruction can be automatically generated after the object to be dried is cleaned and spun dry by a washing and drying integrated machine. Alternatively, the drying instruction can be triggered by the user.

[0059] The first heating unit 4 is located upstream of the adsorption unit 6. In some embodiments, the first heating unit 4 can be used to heat at least part of the adsorption unit 6 to improve the dryness of the adsorption unit 6, thereby improving the moisture absorption effect of the adsorption unit. In another embodiment, the first heating unit 4 can be used to dry the object to be dried to improve the drying effect. In yet another embodiment, the first heating unit 4 can be used to heat at least part of the adsorption unit 6 to improve the dryness of the adsorption unit 6, thereby improving the moisture absorption effect of the adsorption unit, and also used to dry the object to be dried, thereby improving the drying efficiency. The heating temperature of the first heating unit 4 can be set by the operator before the drying system.

[0060] The first drying process can be a drying process performed on the adsorption unit 6, or a drying process performed on the adsorption unit 6 and the object to be dried simultaneously. The specific implementation principles and processes are described in detail in the following embodiments.

[0061] Then, the first heating unit 4 is controlled to stop working, so that the airflow sucked by the suction assembly passes through the adsorption unit 6 and then performs the second drying process on the object to be dried. The first drying process and the second drying process are performed at different times.

[0062] The first drying process and the second drying process are performed at different times, that is, the first drying process and the second drying process are not performed at the same time. In some implementations, the first drying process is performed before the second drying process. That is, when the first drying process is performed, the airflow sucked by the suction assembly passes through the first heating unit 4, is heated, and then passes through the adsorption unit 6 before acting on the object to be dried. Therefore, not only can the heating heat be used to restore the moisture absorption capacity of the adsorption unit, that is, to heat and desorb the adsorption unit 6, but also the object to be dried can be dried simultaneously, that is, the first drying process is implemented. After that, the first heating unit 4 can be turned off, and the airflow sucked by the suction assembly passes through the adsorption unit 6 to further dry the object to be dried, that is, the second drying process is implemented. Since the airflow is not heated during the second drying process, not only can energy be saved, but also the object to be dried can be protected from damage caused by high temperatures. After the heating and desorption process of the adsorption unit 6 is completed, the moisture absorption capacity of the adsorption unit 6 is greatly improved, and the adsorption unit 6 and the suction assembly are used to dry the object to be dried, thereby improving the drying effect.

[0063] In another implementation, the second drying process is performed before the first drying process, that is, the first heating part 4 is not operated first, and the air flow sucked by the suction assembly passes through the adsorption part 6, and then the drying of the object to be dried is performed, that is, the second drying process is implemented, so that not only energy can be saved, but also the object to be dried can be protected from damage caused by high temperature; then the first heating part 4 is controlled to work, and the air flow sucked by the suction assembly is heated by the first heating part 4, then passes through the adsorption part 6, and then acts on the object to be dried, so that not only the heat can be used to restore the moisture absorption capacity of the adsorption part, that is, the adsorption part 6 is heated and desorbed, or the object to be dried is dried at the same time, that is, the first drying process is implemented, so that after the heating and desorption process of the adsorption part 6 is completed, the moisture absorption capacity of the adsorption part 6 is greatly enhanced, and then the adsorption part 6 and the suction assembly are used to dry the object to be dried, thereby improving the drying effect.

[0064] Therefore, in the embodiment, the object to be dried is dried by the first heating part 4 and the adsorption part 6, thereby reducing the water content of the object and improving the drying effect, which can meet the needs of users.

[0065] Based on the above embodiment, in actual application, the drying system can adopt different structures. In a first implementation, as shown in Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 , the suction assembly includes a first suction part 2, and the controller is specifically configured to control the first suction part 2 to work, so that the gas in the containing cavity 102 flows through the first heating part 4 and the adsorption part 6 and then reenters the containing cavity 102, so as to perform the first drying process on the adsorption part 6 and the object to be dried.

[0066] Specifically, the controller first controls the first suction part 2 to suck the gas in the containing cavity 102 to form a first air flow, and then controls the first heating part 2 to heat the first air flow, so that the first heated air flow flows through the adsorption part 6 and then reenters the containing cavity 102, so as to perform the first drying process on the adsorption part 6 and the object to be dried.

[0067] Based on the above embodiment, different structures are adopted for implementation. In an embodiment, as shown in Figure 1 and Figure 2 , the first heating part 4 is directly connected in series with the adsorption part 6, so that this structure is simple and easy to implement.

[0068] In another embodiment, as shown in Figure 4 and Figure 5As shown, a switching valve 5, a first airflow channel 11, and a second airflow channel 12 are also provided between the first heating part 4 and the receiving cavity 102. The switching valve 5 is connected to the first airflow channel 11 and the second airflow channel 12 respectively. The first airflow channel 11 and the second airflow channel 12 are arranged in parallel. The adsorption part 6 is arranged in the first airflow channel 11. The switching valve 5 is used to open the first airflow channel 11 during the first drying process.

[0069] Specifically, the controller controls the switching valve 5 to open the first airflow channel 11, then controls the first suction unit 2 to suction the gas in the receiving cavity 102 to form a first airflow, and then controls the first heating unit 4 to heat the first airflow so that the heated first airflow flows through the adsorption unit 6 and re-enters the receiving cavity 102 to perform a first drying treatment on the adsorption unit 6 and the object to be dried.

[0070] Thus, the airflow drawn from the receiving cavity 102 by the first suction section 2, i.e., the first airflow, is heated by the working first heating section 4. The resulting first hot airflow then flows through the adsorption section 6 and re-enters the receiving cavity 102. As the first heated airflow flows through the adsorption section 6, it heats and desorbs the adsorption section 6, thereby improving the dryness of the adsorption section 6 and thus improving the moisture absorption effect of the adsorption section 6. When the first heated airflow flows through the adsorption section 6 and re-enters the receiving cavity 102, the high temperature of the first heated airflow dries the object to be dried. Therefore, in this embodiment, the dehumidification treatment of the adsorption section 6 and the drying of the object to be dried are carried out simultaneously, thereby further improving the drying efficiency.

[0071] In the second implementation, the controller controls the first suction unit 2 to work so that the gas in the receiving cavity 102 flows through the first heating unit 4 and the adsorption unit 6 and is then discharged to the outside of the receiving cavity 102 to perform the first drying treatment on the adsorption unit 6.

[0072] Specifically, the first suction section 2 is first controlled to suction the gas in the receiving cavity 102 to form a second airflow; then the first heating section 4 is controlled to heat the second airflow so that the heated second airflow flows through the adsorption section 6 and is then discharged to the outside of the receiving cavity 102 to perform a first drying treatment on the adsorption section 6.

[0073] Specifically, such as Figure 7 and Figure 8 As shown, an exhaust valve 8 is also provided on the first airflow channel 11, and the exhaust valve 8 is located downstream of the adsorption section 6; wherein, the exhaust valve 8 is used to open during the first drying process so that the gas in the accommodating cavity 102 flows through the first heating section 4 and the adsorption section 6 and is then discharged to the outside of the accommodating cavity 102.

[0074] Therefore, the air flow extracted from the containing cavity 102 by the first suction part 2 is heated by the working first heating part 4, and then the obtained second heated air flow re-enters the containing cavity 102 after flowing through the adsorption part 6, so that the second air flow heats and desorbs the adsorption part 6 when flowing through the adsorption part 6, thereby improving the dryness of the adsorption part 6 and the moisture absorption effect of the adsorption part, and the second heated air flow flowing through the adsorption part 6 is discharged to the outside of the containing cavity 102 through the exhaust valve 8, that is, no longer re-enters the containing cavity 102.

[0075] Further, the controller is specifically configured to control the first heating part 4 to stop working, and control the first suction part 2 to extract the air in the containing cavity 102, and the extracted air re-enters the containing cavity 102 after flowing through the adsorption part 6, so as to perform a second drying process on the object to be dried.

[0076] In specific applications, for the structures of Figure 1 and Figure 2 , the first heating part 4 can be directly controlled to stop working. For the structures of Figure 7 and Figure 8 , the switching valve 5 is controlled to be in communication with the first air flow channel 11, so that the first heating part 4 is directly communicated with the adsorption part 6, the exhaust valve 8 is closed, and the first heating part 4 is controlled to stop working. After the first drying, the first heating part 4 does not need to heat the air flow, and the air flow directly flows into the adsorption part 6 after the regeneration and desorption treatment, so that the adsorption part 6 absorbs the water vapor in the air flow, thereby making the air flow contain less water, that is, the air flow is drier. After the drying treatment of the adsorption part 6, the water content of the air flow is further reduced, thereby improving the effect of the second drying process on the object to be dried.

[0077] The dried air flow flows into the containing cavity 102, and the suction part continuously extracts the air in the containing cavity 102, so that the dried air flow can carry a large amount of water vapor out of the containing cavity 102 to achieve the purpose of the second drying process on the object to be dried. In the second drying process, the first heating part 4 stops heating, so that the temperature of the air flow is always low, thereby avoiding the damage of high temperature to the object to be dried.

[0078] It is worth noting that in the embodiment, the first heating part 4 stops heating, so that the air flow of the first suction part 2 flows through the first heating part 4 but is not heated by the heating part.

[0079] Further, as Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 and Figure 11As shown, the controller is further configured to control the switching valve 5 to open the second airflow passage 12, so that the gas sucked by the first suction part 2 from the containing cavity 102 flows through the first heating part 4 and then re-enters the containing cavity 102 to perform a third drying process on the object to be dried.

[0080] Specifically, by controlling the switching valve 5 to open the second airflow passage 12, that is, to make the second airflow passage 12 communicate with the first heating part 4, the airflow heated by the first heating part 4 is directly introduced into the containing cavity 102, thereby reducing heat loss, improving the drying effect on the object to be dried, and improving the flexibility of the drying method. The first suction part 2 continuously sucks air in the containing cavity 102, so that the moisture is also discharged from the containing cavity 102 along with the sucked air.

[0081] In order to further improve the drying effect, in another embodiment, as shown in Figure 2 and Figure 5 , a heat exchanger 3 is further arranged between the first heating part 4 and the containing cavity 102, and the heat exchanger 3 is located downstream of the first suction part 2. The heat exchanger 3 is configured to condense and dry the gas sucked by the first suction part 2.

[0082] The heat exchanger 3 is controlled to work to condense and dry the gas sucked by the first suction part 2.

[0083] In a specific application, the heat exchanger 3 is used to condense and dry the gas sucked by the first suction part 2, so that the water vapor in the gas is condensed into water droplets to achieve the purpose of drying the gas.

[0084] Specifically, in an embodiment, during the first drying process, the heat exchanger 3 is controlled to work, the first suction part 2 is controlled to suck the gas in the containing cavity 102 to form a first airflow, the first airflow flows through the heat exchanger 3 to condense and dry the first airflow, and then the condensed and dried first airflow is heated by the first heating part 4. The first hot airflow obtained by heating flows through the adsorption part 6 and then re-enters the containing cavity 102 Figure 2 The airflow flow direction of the structure shown in Figure 3 is shown by the arrow of Figure 5 , the airflow flow direction of the structure shown in Figure 6 is shown by the arrow of ), to perform a first drying process on the adsorption part 6 and the object to be dried. Thus, the first airflow is condensed and dried before being heated, thereby improving the drying property of the first airflow, and further improving the effect of the first drying process on the adsorption part 6 and the object to be dried.

[0085] In another embodiment, as shown in Figure 8As shown, in the process of the first drying treatment, the heat exchanger 3 is controlled to work, so that after the first suction part 2 controls the gas in the containing cavity 102 to form the second gas flow, the second gas flow flows through the heat exchanger 3 to condense and dry the second gas flow, and then the condensed and dried second gas flow is heated by the first heating part 4, so that the second hot gas flow obtained by heating flows through the adsorption part 6 and is discharged to the outside of the containing cavity 102, so as to perform the first drying treatment on the adsorption part 6. Thus, the second gas flow is condensed and dried before being heated, so as to improve the dryness of the second gas flow, and further improve the effect of the subsequent first drying treatment on the adsorption part 6.

[0086] Similarly, in the process of the second drying treatment, the heat exchanger 3 is controlled to work, and the gas sucked by the first suction part 2 from the containing cavity 102 first flows through the heat exchanger to condense and dry, and then the condensed and dried gas flows through the adsorption part 6 and reenters the containing cavity 102, so as to perform the second drying treatment on the object to be dried. Thus, the gas is condensed and dried first, so as to improve the dryness of the gas, and further improve the effect of the subsequent second drying treatment on the object to be dried.

[0087] Further, as shown in Figure 5 and Figure 8 , in the process of the third drying treatment, the switching valve 5 is controlled to open the second gas flow channel 12, and the heat exchanger 3 is controlled to work. The gas sucked by the first suction part 2 from the containing cavity 102 first flows through the heat exchanger to condense and dry, and then the condensed and dried gas reenters the containing cavity 102 after flowing through the first heating part 4 (see the arrow in Figure 9 for details), so as to perform the third drying treatment on the object to be dried. Thus, the gas is condensed and dried by the heat exchanger 3 before being heated, so as to improve the dryness of the gas, and further improve the effect of the subsequent third drying treatment on the object to be dried.

[0088] In order to improve the dehumidification effect of the adsorption part 6, in some other embodiments, as shown in Figure 10 and Figure 11 , the drying module further comprises a second heating part 9 for at least partially heating the adsorption part 6, and a second suction part 10 located upstream of the second heating part 9. The controller is further configured to control the gas sucked by the second suction part 10 to flow through the adsorption part 6 after passing through the second heating part 9, so as to desorb the water in the adsorption part 6.

[0089] When the adsorption part 6 adopts a rotatable rotating disc structure, the second heating part 9 can heat the gas flow sucked by the second suction part 10, and the heated gas flow can heat different areas of the rotating rotating disc, so as to heat and desorb different areas of the rotating disc by high temperature, and further improve the dehumidification effect.

[0090] In a specific application, the second heating part 9 can heat and adsorb the adsorption part 6 in combination with the first heating part 4, or the second heating part 9 can heat and adsorb the adsorption part 6 alone, which will be described in detail below.

[0091] Specifically, in the first implementation, the second heating part 9 heats and adsorbs the adsorption part 6 at the same time as the first heating part 4, so as to further improve the dehumidification effect of the adsorption part 6. Specifically, the controller is further configured to control the first suction part 2 to work and the switching valve 5 to conduct the first gas flow channel 11 during the process of desorbing the adsorption part 6 by the second suction part 10 and the second heating part 9, so that the gas in the containing cavity 102 flows through the first heating part 4 and the adsorption part 6 to desorb the moisture of the adsorption part 6.

[0092] Therefore, the adsorption part 6 can be heated by the gas flow heated by the first heating part 4 and the gas flow heated by the second heating part 9 at the same time, so as to improve the drying effect and efficiency of the adsorption part 6.

[0093] In the second implementation, only the second heating part 9 heats and adsorbs the adsorption part 6.
