Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0010] Furthermore, terms such as "first," "second," etc. in this disclosure are used for descriptive purposes only and are not to be construed as indicating or implying the relative importance or number of such technical features. Consequently, features defined as "first" or "second" may explicitly or implicitly include at least one such feature.

If the combinations of embodiments are mutually inconsistent or infeasible, such combinations of embodiments do not exist and are not considered to fall within the scope of protection of the present disclosure.

[0011] The present disclosure will now be described with reference to specific embodiments in conjunction with the accompanying drawings.

[0012] 3 shows a drying module D according to the present disclosure. The drying module D can be applied to various devices requiring dehumidification, such as a dryer, a washer-dryer, a clothes dryer, a dehumidifier, and a dishwashing device H. For convenience of explanation, the present disclosure will be described using an example in which the drying module D is applied to a dishwashing device H, which is a dishwasher. The same applies when the drying module D is applied to other devices.

[0013] Referring to Figures 1 to 3, the tableware processing device H has a washing chamber H1 and the above-mentioned drying module D, and the washing chamber H1 is connected to the moisture absorption passage air inlet D21 and the moisture absorption passage air outlet D22, forming a circulating moisture absorption flow within the washing chamber H1 and the moisture absorption passage D2.

[0014] The drying module D includes a moisture absorbing and dehumidifying member D1, a moisture absorbing passage D2, and a dehumidifying passage D3. The moisture absorbing and dehumidifying member D1 includes a moisture absorbing rotary wheel assembly D11, a rotary wheel housing D12, and a rotary wheel drive mechanism D13. The moisture absorbing passage D2 is provided with a moisture absorbing passage air inlet D21, a moisture absorbing passage air outlet D22, and a moisture absorbing passage fan D23. The dehumidifying passage is provided with a dehumidifying fluid driving unit D33, a dehumidifying heating assembly D34, and a dehumidifying condensing assembly D35. A moisture absorbing heating assembly, a moisture absorbing condensing assembly, and / or a moisture absorbing filtering assembly may be selectively provided within the moisture absorbing passage D2, and a dehumidifying filtering assembly may be selectively provided within the dehumidifying passage D3.

[0015] The hot and humid air in the cleaning chamber H1 enters the moisture absorption passage D2 through its air inlet. When the moisture absorption passage D2 fan is activated, the air circulates through the cleaning chamber H1 and the drying module D, forming a circulating moisture absorption flow. The moisture absorption passage D2 fan draws moist air from the cleaning chamber H1 through the moisture absorption passage D2 air inlet of the drying module D, passes through itself, and then discharges it into the moisture absorption area D1211 between the moisture absorption rotary wheel assembly D11 and the bottom of the rotary wheel housing D12. The moist air passes from bottom to top through the wheel disc D111 of the moisture absorption rotary wheel assembly D11, becomes dry air, and then re-enters the cleaning chamber H1 through the moisture absorption passage D2 air outlet. This circulation achieves cavity drying of the cleaning chamber H1.

[0016] In some embodiments, the drying module D is mounted on the top, side or bottom of the cleaning chamber H1.

[0017] The drying module D is installed above the washing chamber H1, effectively utilizing the space between the countertop of the built-in cabinet and the top surface of the dishwashing processing device H, allowing the size of the machine body in the embedded direction to be reduced to adapt to different countertop designs, and also achieving a larger capacity for the washing chamber H1, allowing more standard dishes to be washed with a smaller machine body volume.

[0018] In addition, the drying module D may be mounted on the side or bottom of the cleaning chamber H1, and in some embodiments, the side includes the left side, right side and rear side, i.e., the drying module D may be mounted on the left side of the cleaning chamber H1 or the right side of the cleaning chamber H1 or the rear side of the cleaning chamber H1.

[0019] In some embodiments, the cleaning chamber H1 has a cleaning air inlet H2 and a cleaning air outlet H3, the cleaning air inlet H2 is connected to the air outlet of the moisture absorption passage D2, the cleaning air outlet H3 is connected to the moisture absorption passage air inlet D21, and the cleaning air inlet H2 is provided on the side or bottom of the cleaning chamber H1.

[0020] The washing air outlet H3 passes the hot and humid air in the washing chamber H1 through the moisture absorption passage D2, and the washing air inlet H2 recirculates the dry, hot air after being dehumidified by the moisture absorption rotary wheel assembly D11 into the washing chamber H1, and the dry, hot air dries the dishes in the washing chamber H1. To improve the mass exchange efficiency of the dishes in the washing chamber H1, the washing air inlet H2 is optionally located below the bowl basket, i.e., the washing air inlet H2 may be located at the side or bottom of the washing chamber H1, and if the washing air inlet H2 is located at the side of the washing chamber H1, the washing air inlet H2 must be located below the bowl basket.

[0021] Here, a bowl basket (also called a bowl rack) is provided in the washing chamber H1 and is used to carry tableware such as bowls, plates, and cups. There are multiple bowl baskets, each with a different geometric shape to carry tableware of different sizes. The material of the bowl basket may be plastic, metal, or an inorganic non-metallic material, or a mixture of multiple materials (e.g., plastic embedded with metal, inorganic non-metallic material wrapped in metal) may be used.

[0022] In some embodiments, the dishwashing machine H further includes a sensor H4, which may be a temperature sensor, for detecting the real-time temperature of the washing chamber H1. The controller controls the dishwashing machine H to activate the drying module D after the dishwashing machine H stops washing and completes draining. In some embodiments, the heating power of the dehumidifying heating element D343 or the power of the auxiliary heating element may be adjusted based on the real-time temperature to obtain a preset temperature in the washing chamber H1. In particular, the auxiliary heating element is disposed in the moisture absorption passage D2, and the airflow heated by the auxiliary heating element is blown into the washing chamber H1.

[0023] In some embodiments, the temperature in the washing chamber H1 is adjusted by the auxiliary heating element, and when the real-time temperature value in the washing chamber H1 is equal to or higher than the set temperature value, indicating that the washing chamber H1 has already reached the drying condition, the drying module D is controlled to be activated to dry the dishes in the washing chamber H1. In other embodiments, the dishes may be dried at a low temperature or with cold air, i.e., the auxiliary heating element may be closed or omitted, and the moisture remaining on the dishes may be removed only through the circulating moisture absorption flow formed between the drying module D and the washing chamber H1. In this case, the residual heat from the previous washing procedure may be fully utilized to remove the moisture.

[0024] It should be noted that in some embodiments, the drying module D has two activation conditions, and the drying module D is activated only after the cleaning mode ends and when the real-time temperature value reaches the drying condition; if neither of the two conditions is reached, the drying module D is not activated.

[0025] In some embodiments, a heater is installed in the cleaning chamber H1 to heat the air in the cleaning chamber H1, increasing the energy in the cleaning chamber H1 and raising the temperature until the real-time temperature reaches the set temperature. Here, the heater can have various forms, such as a heat pump, semiconductor heater, vortex tube, or heating wire. Of course, the energy absorbed by the water exchanged by the condensation module is reintroduced into the cleaning chamber H1 to raise the temperature in the cleaning chamber H1, achieving the goals of energy saving and high-efficiency drying.

[0026] In some other embodiments, the sensor H4 may be a humidity sensor, which is used to detect the real-time humidity value of the washing chamber H1, and the controller is used to control the drying module D to stop under the condition that the real-time humidity value is equal to or less than the set humidity value. For example, it can be determined directly based on the sensor data, or by combining the sensor data with appropriate logic, that the dishes in the washing chamber H1 have already been dried.

[0027] If the real-time humidity value is lower than the set humidity value, it means that the humidity value in the washing chamber H1 at that time is low and the dishes in the washing chamber H1 have already been dried, so the drying module D can be controlled to stop.

[0028] Other sensors, such as sensor H4, may be installed, including, but not limited to, particle sensors, conductivity sensors, rotational speed sensors, and pressure sensors. The location of sensor H4 is not particularly limited and may be located in the moisture absorption passage D2, the dehumidification passage D3, near the dehumidification heating element D343, or near the dehumidification condensation assembly D35. For example, if a temperature or humidity sensor is installed at the air inlet of moisture absorption passage D2, the sensor can detect the environment in the bowl wash chamber before drying and automatically adjust the appropriate procedure to heat the bowl wash chamber to the temperature required for drying before drying. The output humidity data can be used as a reference for the end of the drying procedure. If a conductivity sensor H4 is installed at the air inlet of moisture absorption passage D2, the sensor can detect the hardness of the bowl wash water, the bowl wash water filling level, and the degree of dirt in the bowl wash water, and then perform corresponding operations such as adjusting the water quality of the dishwasher or opening the water inlet valve to refill the water.

[0029] The drying module D includes a moisture absorbing and dehumidifying member D1, a moisture absorbing passage D2, and a dehumidifying passage. The moisture absorbing and dehumidifying member D1 includes a moisture absorbing rotary wheel assembly D11, a rotary wheel housing D12, and a rotary wheel drive mechanism D13. The moisture absorbing passage D2 is provided with a moisture absorbing passage air inlet D21, a moisture absorbing passage air outlet D22, and a moisture absorbing passage fan D23. The dehumidifying passage D3 is provided with a dehumidifying fluid driving unit D33, a dehumidifying heating assembly D34, and a dehumidifying condensing assembly D35. Furthermore, the moisture absorbing passage D2 may optionally include a moisture absorbing heating assembly, a moisture absorbing condensing assembly, and / or a moisture absorbing filtering assembly, and the dehumidifying passage D3 may optionally include a dehumidifying filtering assembly.

[0030] Here, the moisture absorption heating assembly is used to heat the moisture absorption flow to increase the temperature of the moisture absorption flow and improve drying efficiency. The moisture absorption heating assembly is located near the air outlet of the moisture absorption passage D2 of the drying module D, thereby heating the air dried by the moisture absorption heating assembly and preventing evaporated moisture from condensing on the inner wall of the moisture absorption passage D2. The moisture absorption heating assembly can determine whether to heat and the heating power based on the detected value of the temperature sensor.

[0031] The moisture absorbing condensing assembly is configured to further condense and dehumidify the moisture absorbing flow. The moisture absorbing condensing assembly is located near the air inlet of the moisture absorbing passage D2 of the drying module D, thereby pre-dehumidifying the hot and humid air from the washing chamber and improving drying efficiency.

[0032] By providing a moisture absorbing filtering assembly upstream of the moisture absorbing and dehumidifying member D1 in the moisture absorbing passage D2, particularly at the air inlet of the moisture absorbing passage D2, impurities in the moisture absorbing flow can be filtered and the moisture absorbing passage D2, particularly the moisture absorbing and dehumidifying member D1, can be protected from contamination by impurities.

[0033] The drying module D can be pre-assembled as a single pre-assembled module, particularly prior to the complete assembly of the tableware processing device H. The pre-assembled module consists of only one integrally constructed module lower housing and multiple separate upper housings, which together with the upper housings form multiple chambers to accommodate one or more of the functional assemblies, such as the moisture-absorbing rotary wheel assembly D11, the moisture-absorbing passage D2 fan, the dehumidifying fluid driving unit D33, the rotary wheel driving mechanism D13, the moisture-absorbing heating assembly, the moisture-absorbing condensing assembly, the dehumidifying heating assembly D34, and the dehumidifying condensing assembly D35. Such integrated modular manufacturing significantly simplifies assembly and improves assembly efficiency, while shortening or eliminating corresponding connecting pipes to make the structure of the drying module D more compact.

[0034] When the drying module D has only a single-piece lower housing, multiple lugs, preferably four, are integrally molded or fixed to the periphery of the lower housing. Note that the drying module D does not contact the wash chamber when assembled. This prevents the functional modules in the drying module D from being dramatically affected by vibrations in the wash chamber, which is very advantageous for a drying module based on the moisture absorbing and dehumidifying member D1 proposed in the present disclosure. This is because vibrations can cause the wheel disc D111 in the moisture absorbing rotating wheel assembly D11 to rotate stably and collide with the rotating wheel housing D12 or an assembly fixed to the rotating wheel housing D12, resulting in poor sealing and causing the airflow to deviate from the intended flow path.

[0035] As shown in FIG. 3 , the functional modules are connected to each other and wrapped to the top of the dishwasher by lugs. In some embodiments, there are at least four lugs, with at least three of the lugs being individually manufactured and then attached to the edges of the functional modules, and at least one other lug being directly and integrally molded with the rotating wheel housing D12 of the moisture absorbing and dehumidifying member D1. Other numbers of lugs and other connection configurations to the frame are also possible. Consequently, directly fixing the functional modules connected as a whole by the lugs to the frame facilitates assembly while helping to reduce the impact on the drying module D during operation of the dishwasher. Furthermore, it is conceivable to fix each of these functional modules to the dishwasher, in which case it is particularly advantageous to fix the moisture absorbing and dehumidifying member D1 to the frame.

[0036] In some embodiments, the moisture absorption passage air inlet D21 of the moisture absorption passage D2 is fluidly connected to the air outlet of the washing chamber of the dishwashing machine, and the moisture absorption passage air outlet D22 of the moisture absorption passage D2 is fluidly connected to the air inlet of the washing chamber of the dishwashing machine. As shown in Fig. 4, the air outlet of the moisture absorption passage fan D23 is opened along a direction perpendicular to the rotation axis of the moisture absorption rotary wheel assembly D11, and this air outlet is fluidly connected to a moisture absorption inlet configured on the circumferential sidewall of the rotary wheel housing D12 via an air port connection, thereby fluidly connected to the moisture absorption region D1211 of the rotary wheel housing D12. The moisture absorption inlet of the rotary wheel housing D12 is disposed on the circumferential sidewall of the rotary wheel housing D12 between the moisture absorption rotary wheel assembly D11 and the bottom of the rotary wheel housing D12.

[0037] As shown in FIG. 3 , the dehumidifying passage D3 is connected end to end and configured as an internal circulation passage that does not communicate with the external environment. The air outlet of the dehumidifying fluid drive unit D33 is similarly configured to open along a direction perpendicular to the rotation axis of the moisture-absorbing rotary wheel assembly D11, and this air outlet is fluidly connected to the circumferential side wall D3413 of the dehumidifying heating housing D341 of the dehumidifying heating assembly D34 via an air port connection. The dehumidifying heating assembly D34 is fixed to the upper surface of the upper wheel housing D12U of the rotary wheel housing D12 and configured to have a complementary shape thereto. A dehumidifying outlet is configured in the lower end wall D3412 of the dehumidifying heating assembly housing D341, fluidly connected to the dehumidifying region D1212 of the moisture-absorbing rotary wheel assembly D11. This results in a drying module D having a compact structure, particularly in the direction of the rotation axis, which is very advantageous for reducing the height or thickness of the tableware processing device H.

[0038] In alternative embodiments, the moisture absorbing and dehumidifying member may be divided into a moisture absorbing region and a dehumidifying region. In some embodiments, the moisture absorbing region and the dehumidifying region are obtained by separating the same moisture absorbing and dehumidifying member. For example, the moisture absorbing and dehumidifying member is a rotating wheel, and the rotating wheel is divided into a moisture absorbing region and a dehumidifying region. In other embodiments, the moisture absorbing and dehumidifying member is not partitioned, and all regions are used for moisture absorption. Under non-moisture absorbing operating conditions, absorbed moisture must be discharged to prepare for the next moisture absorbing operation stage. For example, the moisture absorbing and dehumidifying member is a moisture absorbing tank filled with moisture absorbing material. In other embodiments, the moisture absorbing and dehumidifying member is a consumable item and needs to be replaced after absorbing moisture once or several times to maintain good moisture absorption effect.

[0039] FIG. 4 shows the flow path of the moisture-absorbing air in the drying module D according to the present disclosure, using arrows. When the moisture-absorbing passage fan D23 is activated, air flows circulating through the cleaning chamber H1 and the drying module D, forming a circulating moisture-absorbing air flow. The moisture-absorbing passage fan D23 draws moist air from the cleaning chamber H1 into the moisture-absorbing passage air inlet D21 of the drying module D, passes through itself, and then discharges it into the moisture-absorbing region D1211 located between the moisture-absorbing rotary wheel assembly D11 and the bottom of the rotary wheel housing D12. The moist air passes from bottom to top through the wheel disc D111 of the moisture-absorbing rotary wheel assembly D11, becoming dry air. This dry air then reenters the cleaning chamber H1 through the moisture-absorbing passage air outlet D22. This circulation process dries the cavity of the cleaning chamber H1.

[0040] FIG. 5 shows the flow path of the dehumidified air in the drying module D according to the present disclosure, indicated by arrows. When the dehumidifying fluid driving unit D33 is activated, an airflow circulates through the dehumidifying passage D3, forming a dehumidified airflow. The dehumidifying fluid driving unit D33 draws in dry air from the dehumidifying condensing assembly D35 and transports it to the dehumidifying heating assembly D34. The heated, dry, high-temperature air enters the dehumidifying zone D1212 and flows from top to bottom through the wheel disc D111 of the moisture-absorbing rotating wheel assembly D11. The dry, high-temperature air absorbs moisture from the wheel disc D111, becoming a high-temperature, humid gas. This high-temperature, humid gas is then transported to the dehumidifying condensing assembly D34, located downstream of the moisture-absorbing rotating wheel assembly D11, where it is condensed and dehumidified to become a dry, low-temperature gas. This dry, low-temperature gas is then transported back to the moisture-absorbing rotating wheel assembly D11. This circulation regenerates the wheel disc D111 of the moisture-absorbing rotating wheel assembly D11, thereby continuously maintaining its moisture-absorbing capacity. 4 and 5 are merely examples of the airflow direction in the moisture absorption passage D2 and the dehumidification passage. In practice, the airflow may traverse from the top to the bottom of the wheel disc D111 in the moisture absorption passage D2, and the airflow may traverse from the bottom to the top of the wheel disc D111 in the dehumidification passage, or may simultaneously traverse from the top to the bottom or from the bottom to the top of the wheel disc D111. This disclosure is not limited to this.

[0041] FIG. 6 is an exploded view showing the moisture absorbing and dehumidifying member D1 of the drying module D according to the present disclosure. FIG. 7 is a three-dimensional view showing the moisture absorbing rotary wheel assembly D11 and the rotary wheel lower housing D12L of the drying module D according to the present disclosure. As shown in FIGS. 6 and 5, the moisture absorbing and dehumidifying member D1 includes a moisture absorbing rotary wheel assembly D11, a rotary wheel housing D12, and a rotary wheel drive mechanism D13. The rotary wheel housing D12 includes a rotary wheel upper housing D12U and a rotary wheel lower housing D12L, which are fixed to each other to form an internal cavity. The rotary wheel housing D12 has a moisture absorbing region D1211 and a dehumidifying region D1212. The moisture absorbing region D1211 communicates with the moisture absorbing passage D2, and the dehumidifying region D1212 communicates with the dehumidifying passage D3. The moisture absorbing rotary wheel assembly D11 is rotatably supported in the internal cavity of the rotary wheel housing D12 along its rotation axis and rotates under the drive of the rotary wheel drive mechanism D13. The moisture-absorbing rotary wheel assembly D11 is driven at its outer periphery by the rotary wheel driving mechanism D13, that is, the rotary wheel driving mechanism D13 applies an output driving force to the outer periphery of the moisture-absorbing rotary wheel assembly D11.

[0042] In some embodiments, the outer peripheral surface of the moisture-absorbing rotating wheel assembly D11 is configured with spur teeth uniformly distributed along the circumferential direction, and the rotating wheel drive mechanism D13 has a pairing transmission mechanism D132 configured as a spur gear. The moisture-absorbing rotating wheel assembly D11 and the rotating wheel drive mechanism D13, particularly the pairing transmission mechanism D132 in some embodiments, are arranged substantially parallel to each other in a direction perpendicular to the rotation axis of the moisture-absorbing rotating wheel assembly D11, i.e., in the radial direction. The rotating wheel housing D12 has a housing portion for housing the moisture-absorbing rotating wheel assembly D11 and the rotating wheel drive mechanism D13, i.e., they share a single rotating wheel housing D12.

[0043] 6 and 7, the rotating wheel housing D12 is provided with at least two pairs of partition members D121 extending opposite each other on the inner end walls of the upper and lower wheel housings D12U, D12L to divide the interior space of the rotating wheel housing D12 into a moisture absorption region D1211 and a dehumidification region D1212, thereby separating the moisture absorption flow and the dehumidification flow inside the rotating wheel housing D12. A gap is provided between the partition members D121 and the wheel disc D111.

[0044] A partition seal member D125 is fixed to the surface of the partition member D121 surrounding the dehumidifying region D1212 that faces the wheel disc D111, and the dimensions of the partition seal member D125 are designed to maintain a small gap between the wheel disc D111 so as not to interfere with the rotation of the wheel disc D111 and to minimize airflow between the moisture absorption region D1211 and the dehumidifying region D1212. The gap between the partition seal member D125 and the wheel disc D111 is set to between 0.2 mm and 5 mm, and such a gap does not interfere with the rotation of the wheel disc D111 in consideration of general axial runout of the rotational movement of the wheel disc D111, and minimizes airflow between the regions. The partition seal member D125 is flexible and configured as, for example, foam, silicone, or soft rubber, which facilitates reducing the risk of damaging the wheel disc D111 when the axial runout of the wheel disc D111 is abnormally severe. In some other alternative embodiments, the partition seal member D125 is configured as a seal burr and contacts the wheel disc D111 in an assembled state to form a contact seal that is rotatable relative to the wheel disc D111.

[0045] A thermal isolation member is further fixed to a surface of the partition member D121 facing the wheel disc D111 of the moisture-absorbing rotary wheel assembly D11 to reduce thermal diffusion between the moisture-absorbing region D1211 and the dehumidifying region D1212, and at least a portion of the thermal isolation member is covered by a partition seal member D125, and a portion of the partition seal member D125 is necessarily closer to the wheel disc D111 than the thermal isolation member. A groove for accommodating the thermal isolation member is formed on the side of the partition seal member D125 facing the wheel disc D111, and the thickness of this groove is greater than the thickness of the thermal isolation member, so that the partition seal member D125 is closer to the wheel disc D111. The partition seal member D125 and / or the thermal isolation member have a shape and dimensions that match the edge of a cavity surrounded by the partition member D121 and, if necessary, the rotary wheel housing D12.

[0046] Here, the thermal isolation member can be made of a thermal insulating material or a thermal insulation material. However, it is also conceivable to manufacture the thermal insulation member using a cheaper metal or alloy, or an inorganic nonmetallic material or a composite material. Here, although metals or alloys have good thermal conductivity, they can still achieve a certain thermal insulation effect after being covered with a sealing member. In other embodiments, the excellent interface reflectivity of the material surface can be used to prevent heat transfer to the outside and achieve a good thermal insulation effect.

[0047] 8 and 9, a partition pressing piece D126 is fixed to the surface of the partition member D121 surrounding the dehumidifying region D1212, facing the wheel disc D111, and the partition pressing piece D126 has a plurality of protrusions provided at intervals, which position the partition seal member D125 and press it against the partition member D121. Here, a groove for accommodating the partition pressing piece D126 is formed on the side of the partition seal member D125 facing the wheel disc D111, and the thickness of this groove is greater than the thickness of the partition pressing piece D126, so that the partition seal member D125 is closer to the wheel disc D111 in the assembled state.

[0048] The partition seal member D125 and the partition presser D126 have a shape and dimensions that match at least a portion of the edge of the dehumidifying region D1212. The partition presser D126 also functions as a thermal isolation member, reducing heat diffusion between the moisture absorption region D1211 and the dehumidifying region D1212. In some embodiments, the partition presser D126 can be made of a thermally insulating or heat-insulating material, but it can also be made of a cheaper metal or alloy, or the heat-insulating member can be made of an inorganic nonmetallic material or composite material. Here, metals or alloys have good thermal conductivity, but can also provide a certain heat insulation effect after being covered with the seal member. In other embodiments, the excellent interface reflectivity of the material surface is used to prevent heat transfer to the outside and provide a good heat insulation effect.

[0049] In some embodiments, the partition holder D126 and the heat separating member are integrally configured, i.e., the partition holder D126 and the heat separating member are molded integrally.

[0050] An air flow guide sheet D127 is further provided on the rotating wheel housing D12, and the air flow guide sheet D127 is provided along the flow direction of the moisture absorbing flow so as to divide the air flow entering the moisture absorbing region D1211 into multiple flows that flow through different regions of the moisture absorbing rotating wheel assembly D11.

[0051] The airflow guide sheet D127 is configured to divide the moisture-absorbing flow entering the rotating wheel housing into multiple airflows, and allow each of the multiple airflows to flow through different regions of the wheel disc D111 of the moisture-absorbing rotating wheel assembly D11. The airflow guide sheet D127 prevents the moisture-absorbing flow from accumulating in the radially outer region of the rotating moisture-absorbing rotating wheel assembly D11 after entering the moisture-absorbing region D1211, thereby improving the uniformity of the moisture-absorbing flow passing through the wheel disc D111 and improving moisture absorption efficiency.

[0052] The air flow guide sheet D127 may be one or more. When there is one air flow guide sheet D127, one end of the air flow guide sheet D127 is provided in the center of the area of ​​the moisture absorption air inlet D21 for moisture absorption flow of the rotating wheel housing D12. Alternatively, multiple air flow guide sheets D127 may be provided, with their ends preferably equally dividing the area of ​​the moisture absorption inlet and preferably arranged substantially uniformly throughout the entire moisture absorption area D1211. The air flow guide sheet D127 is configured to be curved. The number of air flow guide sheets D127 is not particularly limited.

[0053] 8 shows, in an exploded view, a moisture-absorbing rotating wheel assembly D11 of a desiccant module D according to the present disclosure. In some embodiments, the moisture-absorbing rotating wheel assembly D11 includes a wheel disc D111, a peripheral housing member D112, a central housing member D113, a power input member D114, an auxiliary rotating ring D115, a rotating wheel seal member D116, a peripheral vibration damping member D117, and a central vibration damping member D118.

[0054] The wheel disc D111 is made of a renewable moisture-absorbing material. The wheel disc D111 is made of a porous structure or a porous material. It may be in the shape of a disc. In some embodiments, the wheel disc D111 is made of a fiber with excellent moisture absorption capacity, such as cotton. The wheel disc D111 has a central hole symmetrically arranged along the center of the rotation axis, and this central hole is a through hole.

[0055] Fig. 7 is a three-dimensional view showing an example of the moisture-absorbing rotary wheel assembly D11 and the rotary wheel drive mechanism D13 in an engaged state. As shown in Fig. 9, the moisture-absorbing rotary wheel assembly D11 is driven not at its central region but at its outer periphery by the rotary wheel drive mechanism D13. That is, the rotary wheel drive mechanism D13 applies the output driving force to the outer periphery of the moisture-absorbing rotary wheel assembly D11.

[0056] Specifically, the moisture-absorbing rotary wheel assembly D11 includes a power input member D114 that receives power from the rotary wheel drive mechanism D13 to rotate the moisture-absorbing rotary wheel assembly D11. The power input member D114 is integrally molded on the outer circumferential surface of the outer circumferential housing member D112 of the moisture-absorbing rotary wheel assembly D11. Alternatively, a separately manufactured power input member D114 may be fixed to the outer circumferential surface of the outer circumferential housing member D112. The power input member D114 is formed with teeth that are uniformly distributed along the circumferential direction, and in some embodiments, the teeth are spur teeth.

[0057] The rotary wheel drive mechanism D13 includes a rotary wheel drive motor D131 and a pairing transmission mechanism D132. The output shaft of the rotary wheel drive motor D131 is connected to the pairing transmission mechanism D132 so as not to rotate relative to the rotary wheel drive motor D131, and they are connected to each other by, for example, keyway engagement. The pairing transmission mechanism D132 is configured to match the power input member D114 of the moisture-absorbing rotary wheel assembly D11. In the illustrated embodiment, the pairing transmission mechanism D132 is configured as a spur gear that can mesh with the spur teeth of the power input member D114.

[0058] The moisture-absorbing rotating wheel assembly D11 and the rotating wheel drive mechanism D13 are arranged substantially parallel to each other in a direction perpendicular to the rotation axis of the moisture-absorbing rotating wheel assembly D11, i.e., along the radial direction. In some embodiments, the power input member D114 of the moisture-absorbing rotating wheel assembly D11 and the pairing transmission mechanism D132 of the rotating wheel drive mechanism D13 are located in the same plane extending perpendicular to the rotation axis. The rotating wheel drive motor D131 of the rotating wheel drive mechanism D13 is located below the pairing transmission mechanism D132, and in some embodiments, the output shaft of the rotating wheel drive motor D131 extends along a direction parallel to the rotation axis. This allows the moisture-absorbing rotating wheel assembly D11 to have a compact structure. All of the rotating wheel drive mechanisms D13 may be arranged outside the radial dimension of the moisture-absorbing rotating wheel assembly D11, thereby avoiding obstruction of airflow passing through the moisture-absorbing rotating wheel assembly D11.

[0059] In other embodiments not shown, the power input member D114 may be configured with other types of teeth, such as helical teeth or curved teeth. For example, curved teeth may be configured on the end surface of the outer edge of the outer housing member D112 of the moisture-absorbing rotary wheel assembly D11, and the pairing transmission mechanism D132 may be configured as a bevel gear accordingly. In such embodiments, the output shaft of the rotary wheel drive motor D131 is disposed perpendicular to the rotation axis of the moisture-absorbing rotary wheel assembly D11.

[0060] In other embodiments not shown, the power input member D114 may be configured with a smooth surface or profiled grooves uniformly distributed along the circumferential direction, and the pairing transmission mechanism D132 may be configured accordingly as a friction pulley, such as a flat belt transmission pulley, or a meshing pulley, such as a toothed belt pulley, etc. When the pairing transmission mechanism D132 is configured as a friction pulley, the power input member D114 may be configured as a smooth surface with a surface microstructure to increase the friction force.

[0061] In some other embodiments not shown, the rotary wheel drive mechanism D13 may be disposed within the radial dimension range of the moisture-absorbing rotary wheel assembly D11. For example, the rotary wheel drive mechanism D13 may be disposed coaxially with the moisture-absorbing rotary wheel assembly D11. Specifically, the power output end of the rotary wheel drive mechanism D13 is connected to the rotation shaft of the moisture-absorbing rotary wheel assembly D11.

[0062] In some other embodiments not shown, the power input member D114 is made of a friction surface, and the rotary wheel drive mechanism D13 drives the rotation of the power input member D114 by friction force, i.e., a driving method such as a friction wheel is used between the rotary wheel drive mechanism D13 and the power input member D114.

[0063] In some other non-illustrated embodiments, the edge of the moisture-absorbing rotating wheel assembly D11 is provided with a magnetic material to drive the movement of the moisture-absorbing rotating wheel assembly D11 via a moving magnetic field.

[0064] In some other non-illustrated embodiments, the power input member D114 may be configured with sprocket teeth, and the pairing transmission mechanism D132 is accordingly configured as a sprocket.

[0065] As shown in FIG. 6 , in the illustrated embodiment, the rotary wheel drive mechanism D13 and the moisture-absorbing rotary wheel assembly D11 share a single rotary wheel housing D12. In other words, the rotary wheel housing D12 has a housing for housing the moisture-absorbing rotary wheel assembly D11 and the rotary wheel drive mechanism D13, respectively. This configuration is particularly advantageous for sealing the moisture-absorbing and dehumidifying flows, because sealing the entire circumference of the rotary wheel housing D12 prevents the moisture-absorbing and dehumidifying flows from leaking outside the rotary wheel housing D12. Here, a baffle plate is provided in the housing for the rotary wheel drive mechanism D13 of the rotary wheel housing D12, and a sealing member is optionally provided to block airflow from the housing for the moisture-absorbing rotary wheel assembly D11 to the housing for the rotary wheel drive mechanism D13, thereby protecting the rotary wheel drive mechanism D13 from moisture.

[0066] Of course, it is also conceivable that the rotary wheel drive mechanism D13 and the moisture-absorbing rotary wheel assembly D11 have separate, independent housings that are fixed to each other, and in such an embodiment, additional sealing members must be provided to seal the fixed positions of the housings of the rotary wheel drive mechanism D13 and the moisture-absorbing rotary wheel assembly D11.

[0067] By disposing the rotary wheel drive mechanism D13 on the outer periphery of the moisture-absorbing rotary wheel assembly D11, the space around the moisture-absorbing rotary wheel assembly D11 can be utilized very flexibly, and the axial dimension of the moisture-absorbing and dehumidifying member D1 can be reduced and made flat overall, thereby contributing to reducing the overall height or thickness of the tableware processing device H. Furthermore, in such an embodiment, there is no longer a transmission structure inside the rotary wheel housing D12 that obstructs the airflow in the central region of the wheel disc D111, which also contributes to more uniformly guiding the airflow through the wheel disc.

[0068] Since the driving force is applied to the outer peripheral edge of the moisture-absorbing rotating wheel assembly D11, the force applied to the moisture-absorbing rotating wheel assembly D11 is non-centrosymmetric, and in order to enable the moisture-absorbing rotating wheel assembly D11 to rotate more smoothly when driven on the circumferential side, the circumferential roller mechanism D122 and / or the bottom roller mechanism D123 are used to assist its smooth rotation.

[0069] 7, a plurality of bottom roller mechanisms D123 (four in this example) are further provided on the inner bottom wall of the rotating wheel housing D12. Each bottom roller mechanism D123 includes a bottom roller and a bottom roller holder, where the bottom roller is rotatably supported by the bottom roller holder, and the bottom roller holder is disposed in the rotating wheel housing D12. When viewed in a direction perpendicular to the rotation axis of the moisture-absorbing rotating wheel assembly D11, i.e., in the radial direction, the bottom roller is disposed within the radial dimension range of the moisture-absorbing rotating wheel assembly D11. When viewed in a direction parallel to the rotation axis of the moisture-absorbing rotating wheel assembly D11, i.e., in the axial direction, the bottom roller is disposed between the moisture-absorbing rotating wheel assembly D11 and the rotating wheel housing D12, and the distance between the bottom roller and the moisture-absorbing rotating wheel assembly D11 is smaller than the minimum distance between the moisture-absorbing rotating wheel assembly D11 and the rotating wheel housing D12. In the illustrated embodiment, the bottom roller protrudes at least partially from the entire inner bottom wall of the rotating wheel housing D12 toward the moisture-absorbing rotating wheel assembly D11.

[0070] The bottom roller mechanism D123 is non-deformable or slightly deformable. The peripheral surface of the bottom roller may be smooth or uneven. The bottom roller holder is integrally molded or connected to the inner bottom surface of the rotating wheel housing D12, and the bottom roller holder is configured as a hollow member, with a portion of the assembled bottom roller housed in the cavity of the hollow member. A groove for housing the bottom roller mechanism D123 may be provided on the inner bottom surface of the rotating wheel housing D12, and the bottom roller holder may be fixed in the groove, or the bottom roller holder may be directly molded as a groove structure on the inner bottom surface of the rotating wheel housing D12.

[0071] In some embodiments, the bottom roller holder is fixed to the rotating wheel housing D12 by a fixing mechanism configured to allow the axial spacing between the bottom roller holder and the moisture-absorbing rotating wheel assembly D11 to be adjusted in the initial mounting position. Figure 10 exemplarily illustrates a top view of the rotating wheel lower housing D12L having a peripheral roller mechanism D122. A plurality of peripheral roller mechanisms D122 are provided on the inner periphery of the rotating wheel housing D12. The peripheral roller mechanism D122 includes a peripheral roller D1221 and a peripheral roller holder D1222. In some embodiments, the peripheral roller D1221 is rotatably supported by the peripheral roller holder D1222, and the peripheral roller holder D1222 is provided on the inner periphery of the rotating wheel housing D12. When viewed in a direction parallel to the rotation axis of the moisture-absorbing rotating wheel assembly D11, i.e., in the axial direction, the circumferential roller D1221 is disposed within the axial dimension range of the moisture-absorbing rotating wheel assembly D11, i.e., the circumferential roller D1221 is disposed within the thickness range of the moisture-absorbing rotating wheel assembly D1. When viewed in a direction perpendicular to the rotation axis of the moisture-absorbing rotating wheel assembly D1, i.e., in the radial direction, the circumferential roller D1221 is disposed between the moisture-absorbing rotating wheel assembly D1 and the rotating wheel housing D12, and the circumferential roller D1221 is in rolling contact with the outer circumferential surface of the moisture-absorbing rotating wheel assembly D11 for at least a portion of the time during the rotation of the moisture-absorbing rotating wheel assembly D11. In some embodiments, at least a portion of the circumferential roller D1221 protrudes from the entire inner circumferential wall of the rotating wheel housing D12 toward the rotation axis.

[0072] As shown in FIG. 7 , the inner peripheral edge of the lower rotating wheel housing D12L is stepped. A peripheral roller holder D1222 is provided on an end surface of the step extending in a direction perpendicular to the rotation axis, i.e., along the radial direction. The peripheral roller D1221 is rotatably supported by the peripheral roller holder D1222. In this embodiment, at least a portion of the assembled peripheral roller D1221 protrudes toward the rotation axis from the entire inner peripheral wall of the inner peripheral edge of the rotating wheel housing D12 and from the peripheral surface of the step. In this embodiment, the peripheral surface of the step forms the rotating wheel housing seal member D124. That is, the rotating wheel housing seal member D124 is formed by the inner wall of the rotating wheel housing D12 itself and forms a contact seal with the rotating wheel seal member D116 of the moisture-absorbing rotating wheel assembly D11. In other embodiments, the rotating wheel housing seal member D124 may be formed separately and attached to the inner wall of the rotating wheel housing D12, or may be integrally molded with the inner wall of the rotating wheel housing D12. Of course, it does not have to be the structure that protrudes most from the inner peripheral wall of the rotating wheel housing D12 at the axial height where the assembled peripheral roller D1221 is located, but rather the moisture-absorbing rotating wheel assembly D11 needs to be in rolling contact with it for at least part of the time during the rotation process.

[0073] In some embodiments, the rotary wheel seal member D116 may be formed by a surface structure integrally formed on or at the outer peripheral surface of the moisture-absorbing rotary wheel assembly D11, and / or the rotary wheel housing seal member D124 may be formed by a surface structure integrally formed on or at the inner surface of the rotary wheel housing D12. The rotary wheel seal member D116 and / or the rotary wheel housing seal member D124 may be formed from separately manufactured seal members, such as a seal burr or a sealing soft gel. For example, in some embodiments, the rotary wheel seal member D116 is formed by a seal burr fixed on the outer peripheral surface of the moisture-absorbing rotary wheel assembly D11, and the rotary wheel housing seal member D124 is formed by the inner peripheral surface of the rotary wheel housing D12. In other embodiments, the rotary wheel seal member D116 is formed by the outer peripheral surface of the moisture-absorbing rotary wheel assembly D11, and the rotary wheel housing seal member D124 is formed by a seal burr fixed on the inner peripheral surface of the rotary wheel housing D12. In other embodiments, both the rotating wheel seal member D116 and the rotating wheel housing seal member D124 are formed by seal burrs. In some embodiments, the rotating wheel seal member D116 and the rotating wheel housing seal member D124 are contact sealed for rotation relative to each other by surfaces extending parallel to the axis of rotation and / or surfaces extending perpendicular to the axis of rotation.

[0074] For example, in some embodiments, the rotating wheel seal member D116 and the rotating wheel housing seal member D124 are arranged side by side in the same plane along a direction perpendicular to the rotation axis, and the rotating wheel seal member D116 and the rotating wheel housing seal member D124 are contact-sealed so as to rotate relative to each other by their opposing peripheral surfaces. In other embodiments, the rotating wheel seal member D116 and the rotating wheel housing seal member D124 are arranged offset along the rotation axis but immediately adjacent to each other, and the rotating wheel seal member D116 and the rotating wheel housing seal member D124 are contact-sealed so as to rotate relative to each other by their opposing end surfaces. In some embodiments, multiple sets of rotating wheel seal members D116 and rotating wheel housing seal members D124 are provided that are contact-sealed so as to rotate relative to each other, and the rotating wheel seal members D116 and rotating wheel housing seal members D124 are arranged offset from each other to form redundant seals.

[0075] In some embodiments, the sets of rotary wheel seal members D116 and rotary wheel housing seal members D124 are arranged offset from one another along the direction of the rotation axis. In other embodiments, at least one set of the sets of rotary wheel seal members D116 and rotary wheel housing seal members D124 may be arranged between an end face of the moisture-absorbing rotary wheel assembly D11 and the inner top or bottom surface of the rotary wheel housing D12.

[0076] In some embodiments, a plurality of rotating wheel seal members D116 and / or a plurality of rotating wheel housing seal members D124 are provided, where one rotating wheel seal member D116 is in contact sealing with the plurality of rotating wheel housing seal members so as to rotate relative to each other, or one rotating wheel housing seal member D124 is in contact sealing with the plurality of rotating wheel seal members D116 so as to rotate relative to each other.

[0077] As a result, when the moisture-absorbing rotating wheel assembly D11 is offset radially, the circumferential roller mechanism D122 acts to restrict the moisture-absorbing rotating wheel assembly D11 in the form of rolling contact, thereby assisting the moisture-absorbing rotating wheel assembly D11 to travel along the set rotational trajectory without encountering significant rotational resistance, and in particular preventing it from directly colliding with the rotating wheel housing D12 itself, thereby reducing the risk of damage to the moisture-absorbing rotating wheel assembly D11.

[0078] In the illustrated embodiment, in the initial mounting position, the circumferential roller mechanism D122, and in some embodiments the circumferential roller D1221 in particular, is in rolling contact with the outer peripheral surface of the moisture-absorbing rotating wheel assembly D11, preferably without being pressed against each other.

[0079] As a result, the circumferential rolling mechanism D122 can always assist the rotation of the moisture-absorbing rotating wheel assembly D11 without significantly increasing the rotational resistance of the moisture-absorbing rotating wheel assembly D11, preventing radial oscillation of the moisture-absorbing rotating wheel assembly D11 while it is rotating and ensuring its smooth rotation.

[0080] In some other embodiments, in the initial mounting position, there is a small gap between the circumferential roller mechanism D122, particularly the circumferential roller D1221 in some embodiments, and the outer circumferential surface of the moisture-absorbing rotating wheel assembly D11, so that the moisture-absorbing rotating wheel assembly D11 does not come into contact with the circumferential roller mechanism D122 when rotating about a set rotation axis, but comes into rolling contact with the circumferential roller mechanism D122 only when the moisture-absorbing rotating wheel assembly D11 is offset in a direction perpendicular to the rotation axis, i.e., in the radial direction, thereby enabling the circumferential roller mechanism D122 to protect the moisture-absorbing rotating wheel assembly D11 from directly colliding with the rotating wheel housing D12.

[0081] The peripheral roller mechanism D122 is configured to be deformable. In the illustrated embodiment, the peripheral roller D1221 in the peripheral roller mechanism D12 is configured to be flexible and deformable. This allows the moisture-absorbing rotating wheel assembly D11 to be offset in the radial direction, and the flexible and deformable characteristics of the peripheral roller D122 can be used to buffer such offset.

[0082] In additional or alternative embodiments, the peripheral roller holder D1222 in the peripheral roller mechanism D122 is configured to be offsettable, so that when the moisture-absorbing rotating wheel assembly D11 is offset in the radial direction, the peripheral roller holder D1222 is pressed and offset, changing the distance between the peripheral roller D1221 and the rotation axis or set rotation axis relative to the moisture-absorbing rotating wheel assembly D11. In one embodiment, the peripheral roller holder D1222 itself is configured to be elastically deformable. In another embodiment, the peripheral roller holder D1222 is configured to move as a whole along a sliding track to change the distance from the rotation axis, and in some embodiments, an elastic reset member, such as a spring, is fixed to the rotating wheel housing D12 to return the peripheral roller holder D1222 to its initial position. Here, the sliding track may be composed of a slider provided on the circumferential roller holder D1222 so as to be engageable with a groove provided on the rotating wheel housing D12, or the sliding track may be composed of a guide engagement claw provided on the circumferential roller holder D1222 so as to be engageable with a guide protrusion provided on the rotating wheel housing D12.

[0083] As shown in Fig. 10, six circumferential roller mechanisms D122 are provided on the inner circumferential edge of the rotating wheel housing D12. In order to clearly show the circumferential roller holders D1222, in the illustrated embodiment, these circumferential roller mechanisms D122 are uniformly distributed on the same circumference on the inner circumferential edge of the rotating wheel housing. Circumferential roller supports D1222 are provided with circular holes into which the rotation shafts of the circumferential rollers D1221 are inserted. The circumferential roller holders D1222 may be molded integrally with the rotating wheel housing D12, or may be manufactured separately and then fixed to the rotating wheel housing D12. Since the turnplate D111 is driven in the circumferential direction, a certain degree of eccentric force is generated on the turnplate D111, so the circumferential roller mechanisms D122 may be arranged non-uniformly, for example, more circumferential roller mechanisms D122 may be provided on the side farther from the contact portion between the rotary wheel drive mechanism D13 and the moisture-absorbing rotary wheel assembly D11 to offset the effect of the eccentric force, and fewer circumferential roller mechanisms D122 may be provided on the side closer to the contact portion between the rotary wheel drive mechanism D13 and the moisture-absorbing rotary wheel assembly D11. For example, if the rotary wheel drive mechanism D13 and the moisture-absorbing rotary wheel assembly D11 interact in the form of gear meshing, the gear meshing portion is the contact portion between the rotary wheel drive mechanism D13 and the moisture-absorbing rotary wheel assembly D11, and in this case, it is advantageous to provide more circumferential roller mechanisms D122 on the side farther from the gear meshing portion. Furthermore, for example, when the rotating wheel drive mechanism D13 and the moisture-absorbing rotating wheel assembly D11 interact in the form of a pulley, the mutual pressing position between the belt in the rotating wheel drive mechanism D13 and the outer peripheral edge of the moisture-absorbing rotating wheel assembly D11 is the contact point between the rotating wheel drive mechanism D13 and the moisture-absorbing rotating wheel assembly D11, and in this case, it is advantageous to provide more peripheral roller mechanisms D122 on the side away from the pressing point.

[0084] In some embodiments, the circumferential roller holder D122 is fixed to the rotating wheel housing D12 by a fixing mechanism, and the fixing mechanism is configured to be able to adjust the radial distance between the circumferential roller holder D122 and the moisture-absorbing rotating wheel assembly D11 at the initial mounting position. This makes the circumferential roller mechanism D122 applicable to moisture-absorbing rotating wheel assemblies D11 of various sizes and applicable to various modes, such as the mode in which the circumferential roller mechanism D122 contacts the moisture-absorbing rotating wheel assembly D11 in the initial state and the mode in which the circumferential roller mechanism D122 does not contact the moisture-absorbing rotating wheel assembly D11 in the initial state.

[0085] FIG. 11 exemplarily illustrates the circumferential roller D1221. In some embodiments, the circumferential surface of the circumferential roller D1221 is substantially smooth. In other embodiments, the circumferential surface of the circumferential roller D1221 has an uneven surface structure. The circumferential roller D1221 includes a roller body D1223 and a rotation shaft D1224. In some embodiments, the roller body D1223 is rotatable about the rotation shaft D1224, and the rotation shaft D1224 and the circumferential roller holder D1222 may be connected, for example, locked, so as not to rotate relative to each other. In other embodiments, the roller body D1223 is not rotatable about the rotation shaft D1224, and the rotation shaft D1224 and the circumferential roller holder D1222 may be connected so as to rotate relative to each other. The peripheral roller D1221 includes an inner rim D1225, an outer rim D1226, and spokes D1227 connecting the inner rim D1225 and the outer rim D1226. At least two of the spokes D1227 are flexibly deformable, and the connecting line formed at the connection between the inner rim D1225 and the outer rim D1226 does not pass through the rotation axis of the roller D1221. The inner rim D1225 can be understood as the rotation axis D1224 or a tube sleeved around the rotation axis D1224. Of course, the spokes D1227 can be replaced with a flexible material, such as foam or a silicone ring, and the flexible material is sleeved around the outside of the inner rim D1225, and then the outer rim D1226 is sleeved around the outside of the flexible material. The outer rim D1226 can be configured to be rigid or flexible.

[0086] The above-described peripheral drive configuration has at least the following advantages: The rotary wheel drive mechanism D13 arranged on the outer periphery of the moisture-absorbing rotary wheel assembly D11 allows for highly flexible use of the space around the moisture-absorbing rotary wheel assembly D12, allowing the axial dimension of the moisture-absorbing and dehumidifying member D1 to be reduced and made flatter overall, thereby contributing to a reduction in the overall height or thickness of the tableware processing device. Furthermore, in these embodiments, inside the rotary wheel housing D12, there is no longer a transmission structure in the central region of the wheel disc D111 that obstructs the airflow, so the airflow through the wheel disc D111 can be guided more uniformly.

[0087] It is also possible to limit the offset of the moisture-absorbing rotating wheel assembly D11 during rotation in a direction perpendicular to the rotation axis of the moisture-absorbing rotating wheel assembly D11, thereby improving the smoothness of operation of the moisture-absorbing rotating wheel assembly D11 and reducing the risk of the moisture-absorbing rotating wheel assembly D11 colliding with the rotating wheel housing D12.

[0088] 8, the outer peripheral housing member D112 is composed of an annularly shaped outer peripheral upper clamp housing D112U and an outer peripheral lower clamp housing D112L. The outer peripheral upper clamp housing D112U has an L-shaped cross section and includes an end segment extending along the radial direction and a circumferential segment extending along the axial direction.

[0089] Similarly, the outer peripheral lower clamp housing D112L has an L-shaped cross section and includes end segments extending radially and a circumferential segment extending axially. The outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L are locked to each other by an engaging buckle and an engaging groove provided thereon, forming a one-sided open groove for receiving the peripheral region of the wheel disc D111 inside. In the locked state, the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L surround the entire outer peripheral surface of the wheel disc D111 and respectively clamp the peripheral region of the wheel disc D111 from the upper and lower end surfaces thereof, thereby connecting the outer peripheral housing member D112 and the wheel disc D111 so that they cannot rotate relative to each other. The upper and lower end surfaces of the wheel disc D111 here refer to surfaces extending radially of the wheel disc D111. Therefore, it is very easy to connect the outer peripheral housing member D112 and the wheel disc D111 so that they cannot rotate relative to each other.

[0090] In some alternative embodiments, the outer peripheral housing member D112 may be composed of two annular housing members having an L-shaped cross section and a circumferential annular housing member, and the two annular housing members having an L-shaped cross section are fixedly connected to the circumferential annular housing member. A housing structure having an open groove formed on the inside can also be considered.

[0091] In some alternative embodiments, the end segments of the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L may be discontinuous in the circumferential direction as long as they function to clamp the wheel disc D111. Furthermore, the fixing between the housing members, for example, the fixing between the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L in this embodiment, can be achieved by means of screws, welding, adhesives, or the like. The design of the outer peripheral housing member D112 can prevent deformation of the wheel disc D111 due to centrifugal force during rotation, particularly deformation at the periphery of the wheel disc D111 after moisture absorption, and can prevent the wheel disc D111 from being damaged by direct collision with the rotating wheel housing D12 due to vibration, etc. Furthermore, the outer peripheral housing member D112 itself can shorten the radial distance between the moisture-absorbing rotating wheel assembly D11 and the rotating wheel housing D12, reducing the amount of airflow that does not pass through the moisture-absorbing rotating wheel assembly, thereby improving moisture absorption efficiency.

[0092] Furthermore, the outer circumferential lower clamp housing D112L is configured to be in rolling contact with the bottom roller mechanism D123, particularly in the initial assembly state, thereby constantly providing support to the moisture-absorbing rotating wheel assembly D11 being rotated by the bottom roller mechanism D123 and substantially eliminating wear due to sliding friction between the moisture-absorbing rotating wheel assembly D11 and the bottom of the rotating wheel housing D12. When viewed from the axial direction, the end segments of the outer circumferential lower clamp housing D112L are configured to at least partially cover the mounting positions of the bottom roller mechanism D123 on the rotating wheel lower housing D12L, allowing the end segments of the outer circumferential lower clamp housing D112L to be in rolling contact with the bottom roller mechanism D123.

[0093] The central housing member D113 is composed of an annular central upper clamping member D113U and a central lower clamping member D113L. The central upper clamping member D113U has an L-shaped longitudinal cross section and includes radially extending end segments and axially extending circumferential segments. Similarly, the central lower clamping member D113L also has an L-shaped longitudinal cross section and includes radially extending end segments and axially extending circumferential segments. Both the central upper clamping member D113U and the central lower clamping member D113L pass through the central hole of the wheel disc D111 and are engaged with each other by an engaging buckle and an engaging groove provided thereon. A one-sided open groove for receiving the central region of the wheel disc D111 is formed on the outside of the central clamping member D113U. It is also possible for only the central upper clamping member D113U or the central lower clamping member D113L to pass through the central hole of the wheel disc D111. In the locked state, the central upper clamping member D113U and the central lower clamping member D113L respectively clamp the wheel disc D111 from the upper and lower end surfaces of the central region thereof, so that the central housing member D113 and the wheel disc D111 are connected so as not to rotate relative to each other. Therefore, it is very easy to connect the outer peripheral housing member D112 and the wheel disc D111 so as not to rotate relative to each other.

[0094] In some alternative embodiments, the central housing member D113 may be composed of two annular housing members having an L-shaped longitudinal cross section and a circumferential annular housing member, and the two annular housing members D113 having an L-shaped longitudinal cross section are fixedly connected to the circumferential annular housing member. A housing structure having an outer groove with an open groove on one side is also conceivable. In other alternative embodiments, the end segments of the central upper clamp housing D113U and the central lower clamp housing D113L may be discontinuous in the circumferential direction as long as they function to clamp the wheel disc D111. Furthermore, the fixation between the housing members, for example, the fixation between the central upper clamp member D113U and the central lower clamp member D113L in this embodiment, can be achieved by means of screwing, welding, adhesive, or the like. The configuration of the central housing member D113 prevents the relatively fragile wheel disc D111 from colliding with a component on the rotation axis, such as a shaft, and from being damaged. This strengthens the fixation of the wheel disc D111 and avoids undesired deformation.

[0095] A power input member D114 is provided on the outer peripheral surface of the outer peripheral upper clamp housing D112U. The power input member D114 may be integrally molded with the outer peripheral upper clamp housing D112U, or may be manufactured separately and then fixed, for example, welded, to the outer peripheral surface of the outer peripheral upper clamp housing D112U. The power input member D114 may be configured with spur teeth uniformly distributed along the circumferential direction. Accordingly, as shown in FIG. 8, the rotating wheel drive mechanism D13 may have an output gear that meshes with the power input member D114. Of course, in alternative embodiments, the power input member D114 may be provided on the outer peripheral surface of the outer peripheral lower clamp housing D112L. Here, the power input member D114 and the rotating wheel drive mechanism D13 may be configured using gear meshing transmission, such as a worm gear transmission or a bevel gear transmission, or a belt transmission, such as a friction belt transmission or a meshing belt transmission, or a chain transmission. Accordingly, the power input member D114 may be configured with helical teeth for a gear transmission type, curved teeth, a smooth surface for a friction belt transmission type, various profile grooves for an interlocking belt transmission type, or sprocket teeth for a chain transmission type. Providing the power input member D114 on the outer peripheral surface of the outer housing member D112 contributes to reducing the thickness of the moisture absorbing / dehumidifying member D1 along the rotation axis, thereby contributing to reducing the overall height or thickness of the tableware processing device. In other alternative embodiments, the power input member D114 is provided on the inner peripheral surface of the central housing member D113, and accordingly, the rotating wheel drive mechanism D13 is disposed in the central hole of the wheel disc D111.

[0096] An auxiliary rotating ring D115 is further provided on the outer circumferential surface of the outer peripheral upper clamp housing D112U. The auxiliary rotating ring D115 and the power input member D114 are arranged to be offset in the direction of the rotation axis. The auxiliary rotating ring D115 may be molded integrally with the outer peripheral upper clamp housing D112U, or may be manufactured separately and then fixed, for example, welded, to the outer circumferential surface of the outer peripheral upper clamp housing D112U. The auxiliary rotating ring D115 is arranged to align with the position of the circumferential roller mechanism D122, particularly the circumferential roller D1221 in some embodiments, and is rollably engaged with the circumferential roller D1221 in the circumferential roller mechanism D122. Of course, in some other embodiments, the auxiliary rotating ring D115 may also be provided on the outer peripheral lower clamp housing D112L.

[0097] The auxiliary rotating ring D115 is configured as an annular protrusion that protrudes to such an extent that it can make rolling contact with the peripheral roller D1221, even though the peripheral roller D1221 is not the most protruding structure at the inner peripheral edge of the rotating wheel housing D12. In other embodiments, the auxiliary rotating ring D115 may be configured as the basic surface itself of the outer peripheral housing member D112. The peripheral surface of the auxiliary rotating ring D115 may be configured smooth or may have an uneven surface structure.

[0098] In some embodiments, the power input member D114, the auxiliary rotating ring D115 and the rotating wheel seal member D116 are completely offset from one another along the direction of the axis of rotation, and in particular are immediately adjacent to one another.

[0099] As shown in Figure 6, in some embodiments, in the initial assembly state, the auxiliary rotating ring D115 and the circumferential roller in the circumferential roller mechanism D122 maintain contact without being significantly pressed against each other, and when the moisture-absorbing rotating wheel assembly D11 starts to rotate, the auxiliary rotating ring D115 comes into rolling contact with the circumferential roller in the circumferential roller mechanism D122, thereby suppressing radial oscillation of the moisture-absorbing rotating wheel assembly D11, thereby ensuring smooth operation of the moisture-absorbing rotating wheel assembly D11 with almost no increase in rotational resistance of the moisture-absorbing rotating wheel assembly D11.

[0100] Of course, it is also conceivable that in the initial assembly state, a small gap exists between the auxiliary rotating ring D115 and the circumferential rollers of the circumferential roller mechanism D122, further reducing the rotational resistance and allowing it to act only when the moisture-absorbing rotating wheel assembly D11 swings in the radial direction. Here, it is particularly advantageous to make the circumferential roller mechanism D122 deformable, and in particular to make the circumferential rollers of the circumferential roller mechanism D122 flexible, because this reduces the risk of the auxiliary rotating ring D115 being damaged when colliding with the circumferential roller mechanism D122.

[0101] As shown in FIG. 8, a rotary wheel seal member D116 is provided at a fixed position on the outer periphery of the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L. The power input member D114, auxiliary rotary ring D115, and rotary wheel seal member D116 are sequentially provided from top to bottom on the outer periphery of the outer peripheral housing member D112, completely offset along the rotation axis. The power input member D114, auxiliary rotary ring D115, and rotary wheel seal member D116 may be arranged in a different order, offset along the rotation axis. Of course, they may also be arranged on the outer periphery of the outer peripheral lower clamp housing D112L, or distributed between the outer periphery of the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L. The power input member D114 and auxiliary rotary member D115 may be integrally formed or, of course, may be formed separately.

[0102] In some embodiments, the rotating wheel seal member D116 forms the maximum diameter of the moisture-absorbing rotating wheel assembly D11, and the circumferential roller mechanism D122 protrudes from the entire inner circumferential wall of the inner periphery of the rotating wheel housing D12 toward the rotation axis and is in rolling contact with the smaller-diameter auxiliary rotating ring D115. In other embodiments, the auxiliary rotating ring D115 forms the maximum diameter of the moisture-absorbing rotating wheel assembly D11, and the rotating wheel housing seal member D124 that engages with the rotating wheel seal is closer to the rotation axis as part of the inner circumferential surface of the rotating wheel housing D12 than the circumferential roller mechanism D122, and the circumferential roller D1221 only needs to protrude from the inner circumferential wall at a certain axial height. Here, if a gap exists between the circumferential roller mechanism D122 and the auxiliary rotating ring D115 in the initial installation position, the size of this gap must be sufficiently small to ensure that the rotating wheel seal member D116 can still rotate relative to the rotating wheel housing seal member D124 even if the moisture-absorbing rotating wheel assembly D11 is radially offset. That is, the auxiliary rotating ring D115 of the moisture-absorbing rotating wheel assembly D11 comes into rolling contact with the circumferential roller mechanism D122 before the deformation capacity of the rotating wheel seal member D116 is completely consumed, thereby preventing the rotating wheel seal member D116 from getting caught on the rotating wheel housing seal member D124.

[0103] In some embodiments, the radially inner side of the rotating wheel seal member D116 covers the fixed positions of the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L, thereby sealing the fixed positions of the outer peripheral upper clamp housing D112U and the outer peripheral lower clamp housing D112L and preventing airflow entering the moisture-absorbing rotating wheel assembly D11 from escaping through the mounting gaps of the outer peripheral housing members. Furthermore, the rotating wheel seal member D116 is configured to extend radially outward in a direction perpendicular to the rotation axis until it comes into relatively rotatable contact with the rotating wheel housing seal member D124 on the inner circumferential surface of the rotating wheel housing D12. "Relatively rotatably contact" means that the contact between the rotating wheel seal member D116 and the rotating wheel housing seal member D124 does not significantly increase the rotational resistance of the moisture-absorbing rotating wheel assembly D11 having the rotating wheel seal member D116. In the illustrated embodiment, the rotary wheel housing seal member D124 is formed by the inner peripheral surface of the rotary wheel housing D12 itself.

[0104] In the illustrated embodiment, the outer peripheral surface of the rotary wheel seal member D116 forms the maximum diameter of the entire moisture-absorbing rotary wheel assembly D11. This allows the radial outer side of the rotary wheel seal member D116 to close the radial gap between the moisture-absorbing rotary wheel assembly D11 and the rotary wheel housing D12, preventing unabsorbed airflow from entering the cleaning chamber through the gap. That is, the rotary wheel seal member D116 in this embodiment has a dual function: on the one hand, it prevents the airflow that has entered the moisture-absorbing rotary wheel assembly D11 from flowing out through the mounting gap of the outer housing member, and on the other hand, it prevents the unabsorbed airflow from bypassing the moisture-absorbing rotary wheel assembly D11 and flowing beyond its periphery, thereby effectively improving moisture absorption efficiency.

[0105] In some embodiments, the inner peripheral surface of the rotating wheel housing D12 may be configured as a rotating wheel housing seal member D124 that protrudes slightly radially inward and makes contact and seals with the rotating wheel seal member D116, thereby reducing the radial dimension of the rotating wheel seal member D116. In this way, the above-described rotary contact seal can be achieved even if the outer peripheral surface of the rotating wheel seal member D116 is not the largest diameter of the entire moisture-absorbing rotating wheel assembly D11. In other embodiments, a separate seal ring is bonded to the inner peripheral surface of the rotating wheel housing D12 at a position coinciding with the rotating wheel seal member D116 and used as the rotating wheel housing seal member D124 that makes contact and seals with the rotating wheel seal member D116, and can be made of the same material as the rotating wheel seal member D116. This allows the radial dimension of the rotating wheel seal member D116 to be reduced and allows for flexibility in adjusting the radial dimension of the rotating wheel seal member D116, allowing for design flexibility in the placement of the rotating wheel seal member D116 on the outer peripheral surface of the outer housing member D112.

[0106] Such individual seal rings protect the rotating wheel housing D12 from wear on the inner circumferential surface and are easily replaceable. Furthermore, it is conceivable to provide multiple rotating wheel seal members D116, which may be offset from one another and positioned at different locations on the outer circumferential surface of the outer circumferential housing member D112 to at least fulfill the dual functions described above, or to redundantly fulfill the dual functions. For example, one rotating wheel seal member D116 may be positioned at a fixed position on the outer circumferential surfaces of the outer circumferential upper clamp housing D112U and the outer circumferential lower clamp housing D112L, and another rotating wheel seal member D116 may be positioned at a different position from the fixed position on the outer circumferential surfaces of either the outer circumferential upper clamp housing D112U or the outer circumferential lower clamp housing D112L, or two other rotating wheel seal members D116 may be redundantly positioned at different positions from the fixed position on the outer circumferential surfaces of the outer circumferential upper clamp housing D112U and the outer circumferential lower clamp housing D112L, respectively.

[0107] 8, the power input member D114, the auxiliary rotating ring D115, and the rotating wheel seal member D116 are arranged in a completely staggered pattern from top to bottom along the rotation axis on the outer peripheral surface of the outer housing member D112. However, it is also conceivable that the power input member D114, the auxiliary rotating ring D115, and the rotating wheel seal member D116 may be arranged in a different order, offset along the rotation axis.

[0108] The moisture-absorbing rotating wheel assembly D11 further includes a deformable perimeter damping member D117 and a central damping member D118. The perimeter damping member D117 is disposed between the outer perimeter surface of the wheel disc D111 and the inner perimeter surface of the outer housing member D112 and utilizes its deformable properties to provide a cushion therebetween. In some embodiments, the perimeter damping member D117 is bonded to the outer perimeter surface of the wheel disc D111. The central damping member D118 is disposed between the end segments of the central housing member D113 and the central region of the wheel disc D111 and utilizes its deformable properties to provide a cushion therebetween.

[0109] A central damping member D118 is provided between an end segment of the central lower clamping member D113L and an end face of the central region of the wheel disc D111. In alternative embodiments, the central damping member D118 may be provided between an end segment of the central upper clamping member D113U and an end face of the central region of the wheel disc D111, or a central damping member D118 may be provided at each of these two locations.

[0110] In some embodiments, the central vibration damping member D118 is bonded to the end surface of the central region of the wheel disc D111. The peripheral vibration damping member D117 and the central vibration damping member D118 are made of, for example, foam. Of course, the peripheral vibration damping member D117 and the central vibration damping member D118 may also be made of other elastically deformable materials. During operation of the tableware processing device H, vibrations may occur, which may lead to vibrations of the entire machine and, as a result, vibrations of the moisture-absorbing rotating wheel assembly D11. In this case, the peripheral vibration damping member D117 and the central vibration damping member D118 can buffer such vibrations in the axial and radial directions, protecting the wheel disc D111, which is usually relatively fragile, from damage.

[0111] In some other embodiments, the moisture-absorbing rotary wheel assembly D11 can be fixed to the rotary wheel housing D12 so as not to rotate relative to the rotary wheel housing D12. Here, the rotary wheel housing D12 is not divided into different sections. Here, the moisture-absorbing rotary wheel assembly D11 is alternately connected to the moisture-absorbing passage D2 and the dehumidifying passage D3. Specifically, when the drying module D operates, the moisture-absorbing rotary wheel assembly D11 first communicates with the moisture-absorbing passage D2 to absorb and dry the cleaning chamber H1. Thereafter, for example, if it is determined based on information from a sensor connected to the moisture-absorbing rotary wheel assembly D11 that the wheel disc D111 of the moisture-absorbing rotary wheel assembly D11 is saturated, the switching structure is used to communicate the moisture-absorbing rotary wheel assembly D11 with the dehumidifying passage D3, thereby regenerating the wheel disc D111 of the moisture-absorbing rotary wheel assembly D11. The rotating wheel drive mechanism D13 provided for rotating the wheel disc D111, dynamic seal members, such as the rotating wheel seal member D116 and the rotating wheel housing D12 seal member for forming the dynamic seal described above, and rotation auxiliary members, such as the peripheral roller mechanism D122, bottom roller mechanism D123, auxiliary rotating ring D115, etc. described above, are omitted for the purpose of reducing costs.

[0112] In some other embodiments, the moisture-absorbing rotary wheel assembly D11 is fixed to the rotary wheel housing D12, but the rotary wheel housing D12 is divided into at least two regions, a moisture-absorbing region D1211 and a dehumidifying region D1212, and the two regions alternately communicate with the moisture-absorbing passage D2 and the dehumidifying passage D3. In some technical solutions, a rotatable pipe rack is provided on the outer periphery of the rotary wheel housing D12, and flexible pipes are connected between the pipe rack and the moisture-absorbing passage D2 and the dehumidifying passage D3, respectively. When the pipe rack rotates, the pipe openings on the pipe rack communicate with the inlets and outlets of at least two regions, respectively.

[0113] FIG. 12 is a three-dimensional view showing the dehumidifying and heating assembly D34 in the drying module D according to the present disclosure. From the perspective of the flow path of the dehumidifying flow, the dehumidifying and heating assembly D34 may be located upstream and / or downstream of the moisture absorbing and dehumidifying member D1. In some technical solutions, the dehumidifying and heating assembly D34 and the moisture absorbing and dehumidifying member D1 are provided separately. In another alternative technical solution, the dehumidifying and heating assembly D34 and the moisture absorbing and dehumidifying member D1 may be integrally molded or fixed by a connecting means, such as screw fastening. The housing of the dehumidifying and heating assembly D34 is configured in a shape complementary to and connected to the rotating wheel housing D12 of the moisture absorbing and dehumidifying member D1. The dehumidifying and heating assembly D34 can determine the heating power based on the detected value of the temperature sensor. Of course, the dehumidifying and heating assembly D34 may be integrally molded or fixed to the moisture absorbing and dehumidifying member D1.

[0114] In some embodiments, the dehumidifying heating assembly D34 may be provided on the air inlet side D33 of the dehumidifying fluid driving unit, or on the air outlet side of the dehumidifying fluid driving unit D33.

[0115] The dehumidifying and heating assembly D34 includes a dehumidifying and heating assembly housing D341, a mesh plate D342, a dehumidifying and heating member D343, and a temperature controller mounting portion D344. The dehumidifying and heating assembly housing D341 is configured as a sector-shaped body having a sector-shaped cross section, and thus has a sector-shaped upper end wall D3411, a lower end wall D3412, a circumferential side wall D3413 extending along the circumferential direction connecting the upper end wall D3411 and the lower end wall D341, and a radial side wall D3414 extending along the radial direction. This sector-shaped body is configured in a shape complementary to the rotating wheel upper housing D12U of the rotating wheel housing D12.

[0116] Specifically, the upper housing D12U of the rotating wheel is configured to have a fan-shaped cutout, which is substantially the same as the fan-shaped shape of the dehumidifying and heating assembly housing D341. A dehumidifying outlet as large as possible is formed in the lower end wall D3412, allowing airflow to flow into the moisture-absorbing rotating wheel assembly D11 through the dehumidifying outlet. The dehumidifying outlet occupies at least 80% or even 90% of the area of ​​the lower end wall D3412. A dehumidifying inlet as large as possible is provided in the circumferential side wall D3413 of the dehumidifying and heating assembly housing D341. The dehumidifying inlet occupies at least 80%, preferably 90%, of the area of ​​the circumferential side wall D3413. This allows the dehumidifying airflow to enter the dehumidifying and heating assembly D34 via the shortest possible path. Furthermore, by providing the dehumidifying inlet on the radial side wall, the dehumidifying flow passes through the dehumidifying rotary wheel assembly more uniformly in the radial direction, and particularly when multiple dehumidifying inlets are provided on two radial side walls or two radial side walls and one circumferential side wall, the dehumidifying flow passes through the dehumidifying rotary wheel assembly D11 more uniformly within the cross-sectional range of the fan-shaped body, thereby improving the regeneration efficiency of the dehumidifying rotary wheel assembly D11.

[0117] The dehumidifying and heating assembly D34 housing is manufactured integrally with the rotating wheel housing D12, and in some other embodiments, the dehumidifying and heating assembly D34 housing is manufactured separately from the rotating wheel housing D12 and fixed to the rotating wheel housing D12. A flexible connecting seal member is provided between the dehumidifying and heating assembly D34 housing manufactured separately from the rotating wheel housing D12 and said rotating wheel housing D12, particularly the rotating wheel upper housing D12U, to prevent the dehumidifying flow from leaking through a gap between the dehumidifying and heating assembly D34 housing and the rotating wheel housing D12.

[0118] The dehumidifying and heating element D343 in the dehumidifying and heating assembly D34 is configured as a heating tube or a PTC heating element laid in one plane. The heating tube is configured in a serpentine or corrugated shape.

[0119] FIG. 13 shows a three-dimensional front view of the mesh plate D342 in the dehumidifying and heating assembly D34 of the drying module D according to the present disclosure. The mesh plate D342 has a shape that matches the dehumidifying outlet and can be fixed to the dehumidifying outlet. The mesh plate D342 has a plurality of through-holes that are distributed as uniformly as possible across the mesh plate D342. Here, the through-holes are distributed in a snake-like pattern across the mesh plate D342. Particularly advantageously, the openings of the through-holes gradually decrease in size along the direction of the dehumidifying flow. In some embodiments, the opening diameter of the through-holes increases toward the dehumidifying inlet and decreases toward the dehumidifying inlet. That is, the opening diameter of the through-holes decreases radially inward. This further improves the uniformity of the dehumidifying flow through the moisture-absorbing rotary wheel assembly.

[0120] FIG. 14 is a three-dimensional rear view of the dehumidifying and heating assembly D34 of the drying module D according to the present disclosure. A dehumidifying and heating element D343 is provided downstream of the mesh plate D342 along the direction of dehumidification flow, i.e., behind the mesh plate D342. The dehumidifying and heating element D343 is configured as a heating tube laid in a serpentine shape within a single plane. Alternatively, the dehumidifying and heating element D343 may be configured using a PTC heating element, which may be, for example, a ceramic heating element and an aluminum pipe. The dehumidifying and heating element D343 is configured to correspond to the shape of the through-holes in the mesh plate D342 and is positioned offset from the through-holes.

[0121] Specifically, the dehumidifying and heating element D343 is offset from the through-hole toward the inflow direction of the dehumidifying airflow, and the dehumidifying airflow faces the dehumidifying and heating element D343 after passing through the through-hole, improving heating efficiency. The area enclosed by the envelope of the dehumidifying and heating element D343 occupies at least 70% of the cross section of the dehumidifying outlet, and the cross-sectional area of ​​the dehumidifying and heating element D343 itself occupies up to 40% of the cross section of the dehumidifying outlet, thereby enabling heat to be supplied within a sufficiently wide range without obstructing the airflow.

[0122] As shown in FIG. 14, the dehumidifying and heating assembly D34 further includes a temperature controller mounting portion D344. The temperature controller mounting portion D344 is also located on the rear surface of the mesh plate, on the side of the area where the through-holes are formed. The temperature controller mounting portion D344 is configured to detect the temperature in the cavity of the dehumidifying and heating assembly D34. The controller of the dishwashing device H controls the dehumidifying and heating member D34 based on the detected temperature. Because the heated dehumidifying flow is prone to turbulence in the cavity of the dehumidifying and heating assembly D34, the cavity temperature directly measured in the cavity space is highly unstable or prone to fluctuations. To achieve as stable a cavity temperature as possible, the temperature controller mounting portion D344 includes a thermally conductive sheet D3441 and a temperature controller D3442. The thermally conductive sheet D3441 completely surrounds the temperature controller D3442. This is particularly advantageous for temperature control of the dehumidifying and heating element, since a more stable and representative cavity temperature can be detected by conducting the temperature to the temperature controller D3442 via the thermally conductive sheet D3441 compared to directly detecting the cavity temperature in the cavity gas.

[0123] FIG. 15 shows a three-dimensional view of the rotary wheel upper housing D12U without the dehumidifying and heating assembly D34 attached in the drying module D according to the present disclosure. The dehumidifying and heating assembly housing D341 is manufactured separately from the rotary wheel housing D12 and fixed to the rotary wheel upper housing D12U. A flexible connecting seal member D3415 is provided between the dehumidifying and heating assembly housing D341 and the rotary wheel upper housing D12U to prevent dehumidifying flow from leaking through the gap between the dehumidifying and heating assembly housing D341 and the rotary wheel upper housing D12U. A connecting heat insulating member D3416 is further provided between the dehumidifying and heating assembly housing D341 and the rotary wheel upper housing D12U to reduce the diffusion of heat from the dehumidifying and heating assembly housing D341 to the outside, especially to the moisture-absorbing region D1212 of the rotary wheel housing D12. The connecting heat insulating member D3416 is partially covered by the connecting seal member D3415.

[0124] To improve the sealing effect, the connecting insulation member may be completely covered by the connecting seal member, with both the dehumidifying and heating assembly housing D341 and the upper housing D12U of the rotary wheel only contacting the connecting seal member. The connecting seal member D3415 and the connecting insulation member D3416 have inner edges that substantially match the shape of the dehumidifying outlet in the dehumidifying and heating assembly housing D341. The connecting seal member is preferably made of foam, silicone, or soft rubber. The insulation member is preferably made of a thermally insulating material. However, it is also possible to manufacture the connecting insulation member using a cheaper metal or alloy, or an inorganic nonmetallic material or composite material. While metals or alloys have good thermal conductivity, they can still achieve a certain level of thermal insulation even when covered by the connecting seal member. In other embodiments, the excellent interface reflectivity of the material surface can be used to prevent heat transfer to the outside and achieve good thermal insulation.

[0125] In some other non-illustrated embodiments, the dehumidifying heating assembly D34 may be a high-temperature end of a semiconductor refrigeration chip, a high-temperature end of a heat pump, or a high-temperature end of a vortex tube, etc., and the corresponding low-temperature end of the semiconductor refrigeration chip, the low-temperature end of the heat pump, or the low-temperature end of a vortex tube is used for the dehumidifying condensing assembly D35, thereby improving energy utilization efficiency.

[0126] FIG. 16 shows, in a three-dimensional view, a dehumidifying condenser pipe assembly D351 of a dehumidifying condenser assembly D35 of a drying module D according to the present disclosure. FIG. 17 shows, in a three-dimensional view, a truncated portion of a dehumidifying condenser assembly housing D352 of a dehumidifying condenser assembly D35 of a drying module D according to the present disclosure. The dehumidifying condenser assembly D35 includes a dehumidifying condenser pipe assembly D351, a dehumidifying condenser assembly housing D352, and a dehumidifying condenser drain pipe. The dehumidifying condenser drain pipe is in communication with the dehumidifying condenser assembly housing D352, and the dehumidifying condenser pipe assembly D351 is fixed to the center of the dehumidifying condenser assembly housing D352 and configured to condense and dehumidify the dehumidified water flowing through the dehumidifying condenser pipe assembly D351. Condensed water is discharged via the dehumidifying condenser drain pipe.

[0127] In some embodiments, the cold trap may be external air, tap water, or a secondary condenser connected to each other by a heat pipe. The dehumidifying condensing assembly D35 may be a natural heat exchange condenser, or a forced heat exchange (e.g., heat pump, semiconductor sink, etc.).

[0128] As shown in Figure 16, the dehumidifying condensation assembly D35 shares one module lower housing with the moisture absorption rotary wheel assembly D11, moisture absorption passage fan D23, and dehumidifying fluid driving unit D33. The dehumidifying condensation pipe assembly D351 is engaged with the module lower housing through a blocking rib and a restricting member, and the upper housing in the dehumidifying condensation assembly housing D352 presses downward against the seal around the dehumidifying condensation pipe assembly D351 to achieve a sealing effect.

[0129] As shown in FIG. 17, a baffle plate D353 is provided between the dehumidifying condensing pipe assembly D351 and the dehumidifying condensing assembly housing D352 to prevent the dehumidifying flow from entering the dehumidifying condensing assembly housing D352 and flowing directly to the outlet of the dehumidifying condensing assembly housing through a gap between the dehumidifying condensing pipe assembly D351 and the dehumidifying condensing assembly housing D352.

[0130] Referring to FIG. 18, in some embodiments, the operation of the dishwashing machine H is as follows.

[0131] Step S11: receive a cleaning command and execute a pre-rinse mode in response to a start command.

[0132] After the user sets the dishes and sets the appropriate washing mode, the dishwashing device H first executes the pre-rinse mode to pre-rinse the dishes, and here, data on the rinse water is collected as an evaluation standard for later water quality detection, and by comparing it with the evaluation standard, data on changes in the degree of dirt can be obtained.

[0133] Here, the cleaning command and the start command may be input by the user or may be automatically triggered by the dishwashing device H.

[0134] Step S12: execute the corresponding cleaning mode according to the cleaning command.

[0135] After pre-rinsing the dishes, the dishwashing device H shifts to a washing mode corresponding to the washing command and starts washing the dishes according to the washing mode.

[0136] Here, the cleaning modes include "super fast cleaning" and "gentle cleaning", and the user can select different cleaning modes according to the actual situation.

[0137] Different washing modes require different water temperatures, which means different degrees of heating of the water. For example, in washing modes such as "super-fast wash" and "gentle wash," when the water temperature is low, dishes are washed mainly by the mechanical force of the water sprayed from the water spray mechanism, to avoid damage to special dishes caused by the thermal shock of the high-temperature water flow.

[0138] The trigger condition for ending the cleaning mode may be the cleaning time, that is, after the cumulative cleaning time in the cleaning mode reaches a preset time, it may be determined that cleaning has ended and the next step may be entered.

[0139] Of course, in addition to this, the condition for ending the cleaning mode may be the number of sprays by the water spray mechanism, and once the number of sprays reaches a preset number, it may be determined that cleaning has ended and the next step may be entered.

[0140] Step S13: Execute the rinse mode.

[0141] After the washing mode is finished, it will automatically switch to the rinsing mode, the rinsing is mainly used to remove residual detergent and calibrate the cleanliness of the dishes after washing, if the set cleanliness is not reached, the rinsing will be repeated, otherwise the drying process will be carried out.

[0142] In other words, during the rinsing mode, it is necessary to determine in real time whether the dishes are cleaned thoroughly. If they are not cleaned, the rinsing mode is performed, and if they are cleaned, the rinsing mode is terminated and the drying mode is entered.

[0143] In some embodiments, the user may skip the pre-rinse mode and / or the wash mode, etc., and directly select the rinse mode to perform a rinse operation on the dishes.

[0144] Step S14: Determine whether the real-time temperature value in the cleaning chamber is equal to or higher than the drying temperature value.

[0145] When washing dishes, some dishes cannot be washed at high temperatures, so it is also necessary to determine the real-time temperature value in the washing chamber before entering the drying procedure, determine whether the drying conditions can be achieved, obtain the desired drying temperature environment, and avoid damage to special dishes.

[0146] The temperature change in the washing chamber is monitored in real time by a sensor, and the temperature in the washing chamber H1 is adjusted in a closed loop using a heating device until the target temperature or temperature range is reached. Of course, by loading a function of the user-defined procedure, an open-loop temperature adjustment step can also be added before drying according to different settings.

[0147] Step S15: if the real-time temperature value is less than the drying temperature value, heat the cleaning chamber.

[0148] If the real-time temperature value is smaller than the drying temperature value, it means that the current temperature value in the washing chamber is low and has not reached the drying condition, so the washing chamber needs to continue to be heated.

[0149] Step S16: The drying mode is executed.

[0150] The drying process may be controlled in an open loop according to a set time, or in a closed loop by detecting parameters such as humidity using sensor H4. During the drying process, the temperature in washing chamber H1 must be continuously monitored and adjusted if it does not meet the set requirements. For example, a temperature sensor may detect the temperature and activate a heating mechanism, such as a heating element, to stabilize the temperature at or within a set range. As described above, the drying process may be stopped when the set drying time has elapsed or when a measuring device, such as a humidity sensor, detects that the humidity in washing chamber H1 has dropped to the set value. In some embodiments, the end of the dishwashing process may also be signaled interactively, such as by a light, sound, mechanical movement, or data transmission.

[0151] In some embodiments, after the rinsing mode is completed, the dishwashing machine may be controlled to execute a low-temperature drying mode. In the low-temperature drying mode, there is no need to adjust the temperature in the washing chamber H1 or control the temperature in the washing chamber H1 to be lower than the set target temperature value or temperature range. Instead, the drying module described above is used to form a dry circulating airflow in the washing chamber H1 to dry the dishes. This avoids problems such as thermal shock to the dishes caused by drying at too high a drying temperature, which could damage the dishes.
