[0003] Most dishwashers on the market currently use hot air drying or adsorption drying technology, but they still have the problem of low drying efficiency and there is still room for improvement. Summary of the Invention

[0004] In a first aspect, the present invention provides a drying system that can improve drying efficiency.

[0005] To achieve the above objectives, the present invention discloses a drying system, including an air handling chamber comprising a dehumidification channel and a regeneration channel; the drying system further includes an adsorption assembly comprising an adsorbent element, the adsorbent element being integral and located on one side of adjacent dehumidification and regeneration channels, a portion of the adsorbent element being located within the dehumidification channel and used to adsorb moisture from humid air; a heating assembly for heating the remaining portion of the adsorbent element located on the regeneration channel side, and causing the remaining portion of the adsorbent element to regenerate and generate reduced moisture; a condensation assembly for condensing the reduced moisture discharged during the regeneration process of the remaining portion of the adsorbent element and generating regenerated dry gas; the adsorption assembly further includes a drive component for switching the adsorbent element between the dehumidification channel and the regeneration channel.

[0006] Optionally, the adsorbent is rotatably connected within the air handling chamber, and the adsorbent is divided circumferentially into a dehumidification zone within the dehumidification channel and a reduction zone within the reduction and regeneration channel. The adsorbent is driven to rotate by the drive member, causing a portion of the adsorbent to cycle from the dehumidification zone to the reduction zone and back to the dehumidification zone.

[0007] Optionally, when viewed along the rotation axis of the adsorption element, both the dehumidification zone and the reduction zone are fan-shaped, and the surface area of ​​the reduction zone is smaller than that of the dehumidification zone.

[0008] Optionally, a dehumidifying fan is provided in the path of the dehumidification channel, and the dehumidifying fan blows the gas to be dehumidified from one side of the adsorption element through the dehumidification zone to the other side of the adsorption element; A regeneration fan is provided in the path of the reduction and regeneration channel. The regeneration fan blows regeneration dry gas from the other side of the adsorbent through the reduction zone to one side of the adsorbent.

[0009] Optionally, the heating assembly includes a heating element located within the reduction and regeneration channel, a gas guide baffle is provided on one side of the heating element, the gas guide baffle covers the reduction zone along the rotation axis of the adsorption element, and the gas guide baffle is provided with a plurality of through gas guide holes.

[0010] Optionally, the outlet of the regeneration fan is connected to a guide hood, and when viewed along the rotation axis of the adsorption element, the outlet of the guide hood is arc-shaped and extends from one end of the reduction zone to the other along the circumference of the adsorption element.

[0014] Optionally, the dehumidification channel has an air inlet and an air outlet, and the washing chamber is connected to the air inlet and the air outlet. The gas to be dehumidified in the washing chamber enters the dehumidification channel from the air inlet, and the dried gas dehumidified by the adsorption element returns to the washing chamber from the air outlet. Meanwhile, the heating component regenerates the remaining portion of the adsorbent after it has become saturated with moisture, generating reduced moisture. This reduced moisture is then condensed by the condensing component to generate regenerated dry gas, which is then returned to the adsorbent.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: a portion of the adsorbent in the dehumidification channel adsorbs moisture in the humid air, while the heating component and condensation component are used to regenerate the remaining portion of the adsorbent after it has been saturated with moisture in the reduction and regeneration channel, thereby enabling the dehumidification process and the reduction and regeneration process to work simultaneously and improving the drying efficiency.

Detailed Implementation

[0018] The present application will be further described in detail below with reference to the accompanying drawings. Example 1

[0019] Reference Figure 1 This application discloses a drying system, referring to... Figure 1The air handling chamber 10 includes a dehumidification channel 1001 and a reduction and regeneration channel 1002. The adsorbent 21 is integral and located on one side of the adjacent dehumidification channel 1001 and reduction and regeneration channel 1002. A portion of the adsorbent 21 on the side of the dehumidification channel 1001 is used to dehumidify the gas to be dehumidified and generate dry gas. The reduction and regeneration channel 1002 is used to cycle the remaining portion of the moisture-saturated adsorbent 21 for reduction and regeneration.

[0020] The drying system includes a shell 1, an adsorption component 2, a heating component 4, and a condensation component 5.

[0021] The housing 1 includes a bottom shell 12 and an upper shell 11 that are fixedly connected, and an air handling cavity 10 is formed between the bottom shell 12 and the upper shell 11.

[0022] The adsorption component 2 includes an adsorption element 21 and a driving element 22.

[0023] Reference Figure 1 and Figure 2 In this embodiment, the adsorption element 21 has a disc-shaped mesh structure. The adsorption element 21 has an inner ring and an outer ring. The inner side of the inner ring and the outer side of the outer ring are respectively provided with an inner sheath 211 and an outer sheath 212. The inner sheath 211 includes an inner retaining sleeve 2111 and an inner protective ring 2112 that clamp the part of the adsorption element 21 near the inner ring in the middle and are interlocked with each other. The outer sheath 212 includes an outer retaining sleeve 2121 and an outer protective ring 2122 that clamp the part of the adsorption element 21 near the outer ring in the middle and are interlocked with each other.

[0024] The inner protective ring 2112 has a central hole 21120 at its center. The bottom of the bottom shell 12 is provided with a mounting post 121 for passing through the central hole 21120. The adsorbent 21 is rotatably connected to the interior of the shell 1 via the inner protective ring 2112, and the outer peripheral sidewall of the outer sleeve 2121 is close to the inner peripheral sidewall of the shell 1, i.e., there is a small gap between the outer peripheral sidewall of the outer sleeve 2121 and the inner peripheral sidewall of the shell 1, so that the gas to be dehumidified passes through the adsorbent 21 as much as possible. In this embodiment, the adsorbent 21 is a molecular sieve. In other embodiments, the adsorbent 21 can also be zeolite particles or other materials that can absorb water and be dehydrated and regenerated.

[0025] In order to enable the adsorption member 21 to rotate around the central axis of the mounting post 121, the outer wall of the outer protective ring 2122 is provided with meshing teeth as driven part 2123 along its circumference. The meshing teeth mesh with a gear as driving part 222. The driving part 222 is driven to rotate by the output shaft of a motor 221. The driving part 222 and the motor 221 constitute the driving member 22. In this embodiment, the driving part 222 is located inside the housing 1, and the motor 221 is located outside the housing 1. The output shaft of the motor 221 extends into the housing 1 and connects to the driving part 222.

[0026] In other embodiments, the motor 221 can directly drive the inner ring of the adsorption member 21 to rotate.

[0027] Reference Figure 1 and Figure 3 In this embodiment, when viewed along the rotation axis of the adsorption member 21, two separating ribs 122 are provided on the bottom shell 12, one end of which extends to the center of the inner ring of the adsorption member 21 and the other end extends to the outer edge of the outer ring of the adsorption member 21. The two separating ribs 122 are distributed sequentially along the circumference of the adsorption member 21.

[0028] Reference Figure 3 The acute angle of the central angle formed between the two separating ribs 122 is close to 90°, thus designating approximately one-quarter of the surface area of ​​the adsorbent 21 as the reduction zone 102 and the remaining three-quarters as the dehumidification zone 101. Both the dehumidification zone 101 and the reduction zone 102 are formed into a near-fan shape, and the surface area of ​​the dehumidification zone 101 is larger than that of the reduction zone 102. The dehumidification zone 101 is located within the dehumidification channel 1001, and the reduction zone 102 is located within the reduction and regeneration channel 1002. In this embodiment, the motor 221 drives the adsorbent 21 to rotate in one direction around the rotation axis, causing a portion of the adsorbent 21 to cycle from the dehumidification zone 101 to the reduction zone 102 and back to the dehumidification zone 101.

[0029] In other embodiments, the surface area of ​​the dehumidification zone 101 is close to the surface area of ​​the reduction zone 102, and the driving member 22 drives the adsorption member 21 to switch between the dehumidification channel 1001 and the reduction and regeneration channel 1002.

[0030] Reference Figure 1 and Figure 4 The bottom of the bottom shell 12 has a boss 123 protruding along the rotation axis of the adsorption member 21. The mounting post 121 is integrally formed at the center of the end face of the boss 123. The end face of the part of the adsorption member 21 near the inner ring is close to the end face of the boss 123. The adsorption member 21 divides the dehumidification channel 1001 into a dehumidification front area 1011 located on the side of the adsorption member 21 facing the boss 123 and a dehumidification rear area 1012 located on the side of the adsorption member 21 away from the boss 123.

[0031] The housing 1 has an air inlet 1010 communicating with the dehumidification front zone 1011. A dehumidifying fan 1013 is connected to the air inlet 1010. The air outlet of the dehumidifying fan 1013 is connected to the air inlet 1010. The air inlet of the dehumidifying fan 1013 is used to draw the gas to be dehumidified into the dehumidification front zone 1011. Specifically, the air inlet of the dehumidifying fan 1013 is connected to the washing cavity 6 of the dishwasher. The dehumidifying fan 1013 blows the gas to be dehumidified from the side of the adsorption member 21 facing the boss 123 through the dehumidification zone 101 and to the other side of the adsorption member 21 away from the boss 123.

[0032] In this embodiment, an air inlet channel 3 is provided between the air inlet of the dehumidifier 1013 and the dishwasher.

[0033] Reference Figure 3 When viewed along the rotation axis of the adsorption element 21, the dehumidifying fan 1013 is located on the outer side of the outer peripheral wall of the adsorption element 21. The air outlet direction of the dehumidifying fan 1013 is parallel to the end face of the adsorption element 21. The air inlet 1010 of the housing 1 forms an air guide duct 30 connecting the air outlet of the dehumidifying fan 1013 and the dehumidification front zone 1011. The air outlet of the air guide duct 30 is arc-shaped, and one arc-shaped end of the air outlet of the air guide duct 30 is close to the dehumidification zone 101 and the reduction zone 102. At the junction of the two zones, the span between the other end of the arc-shaped air outlet of the air guide duct 30 and this end is approximately 90°. The position of the dehumidifying fan 1013 allows the gas to be dehumidified to be blown more towards all positions of the adsorbent 21 in the dehumidification zone 101. Furthermore, because the reduction zone 102 is the furthest along the air outlet path of the dehumidifying fan 1013, every position in the dehumidification zone 101 has ample opportunity to come into full contact with the gas to be dehumidified, improving the dehumidification and drying effect. Additionally, the gas blown out by the dehumidifying fan 1013 will flow more towards the other junction of the dehumidification zone 101 and the reduction zone 102 due to inertia. Thus, within a certain time, the adsorbent 21 will reach moisture saturation most quickly at this other junction, and then, under the action of the driving component 22, it will rotate clockwise, causing this position to be the first to enter the reduction zone 102 for heating and reduction, thereby achieving a more efficient drying effect.

[0034] In other embodiments, the air outlet of the dehumidifier 1013 can be set perpendicular to the end face of the adsorption element 21.

[0035] Reference Figure 1 , Figure 5 and Figure 6 The upper shell 11 includes a fan-shaped heating support cover 111. The heating support cover 111 and the two partition ribs 122 form part of the reduction and regeneration channel 1002. The adsorption member 21 is also close to the partition ribs 122 on the side facing the boss 123. The adsorption member 21 divides the reduction and regeneration channel 1002 into a pre-reduction region 1021 located on the side of the adsorption member 21 away from the boss 123 and a post-reduction region 1022 located on the side of the adsorption member 21 facing the boss 123.

[0036] In this embodiment, the heating component 4 is located in the space of the pre-reduction zone 1021, and the heating component 4 includes a heating element 41 and a gas guide plate 42.

[0037] When viewed along the rotation axis of the adsorbent 21, the heating element 41 is serpentine and extends from the inner side of the fan-shaped reduction zone 102 to the outer side. Both ends of the heating element 41 extend outside the heating support cover 111 for power supply. The air guide baffle 42 is fan-shaped and covers the reduction zone 102. The air guide baffle 42 is provided with multiple air guide holes 420 that penetrate along the rotation axis of the adsorbent 21, thereby providing a uniform airflow to the reduction zone 102.

[0038] In this embodiment, the heating support cover 111 is provided with an arc-shaped reduction inlet 1020 that connects to the reduction pre-zone 1021. A guide hood 54 is provided at the reduction inlet 1020 and is connected to the outlet of the guide hood 54. A regeneration fan 1023 is provided on the side of the guide hood 54 away from the reduction inlet 1020. The outlet of the regeneration fan 1023 is connected to the inlet of the guide hood 54. When viewed along the rotation axis of the adsorbent 21, the outlet of the guide hood 54 is arc-shaped and extends from one end of the reduction zone 102 to the other end along the circumference of the adsorbent 21, so that the airflow entering the reduction pre-zone 1021 can be more uniform. The reduction inlet 1020 and the air inlet 1010 are distributed adjacently in the housing 1 along the circumference of the adsorbent 21.

[0039] Because of the inertia of the outlet of the regeneration fan 1023, the ventilation volume is highest in the innermost area of ​​the air guide baffle 42 near the center of the adsorption component 21. Therefore, in order to improve the uniformity of air intake in the reduction zone 102, the distribution density of the air guide holes 420 on the air guide baffle 42 becomes denser or the diameter of the air guide holes 420 becomes larger along the direction from the inner circle to the outer circle of the fan-shaped air guide baffle 42.

[0040] The regeneration fan 1023 blows the condensed regenerated dry gas from the side of the adsorbent 21 away from the boss 123 through the reduction zone 102 to the side of the adsorbent 21 facing the boss 123.

[0041] Reference Figure 1 and Figure 6 The condenser assembly 5 is located in the post-reduction zone 1022 within the reduction and regeneration channel 1002. The condenser assembly 5 includes a condenser 51 and a receiving component 52 for collecting condensate.

[0042] The receiving component 52 is sealed to the bottom of the bottom shell 12. The receiving component 52 has a receiving cavity 520 for receiving condensate below the condenser 51. The reducing moisture generated by the adsorbent 21 during the reduction and regeneration process in the reduction zone 102 is condensed into liquid after passing through the condenser 51 and drips into the receiving cavity 520. At the same time, the reducing moisture is transformed into regenerated dry gas and is blown back to the reduction pre-zone 1021 by the regeneration fan 1023.

[0043] The receiving part 52 is provided with a condensate outlet communicating with the receiving cavity 520. The receiving part 52 is provided with a condensate pump 55. The condensate outlet is connected to the inlet of the condensate pump 55. The outlet of the condensate pump 55 is connected to the washing cavity 6 of the dishwasher or the outside of the dishwasher.

[0044] The condenser 51 includes a condenser tube 511 and condenser fins 512 connected to the outside of the condenser tube 511. The condenser tube 511 has a condensation channel. The condenser 51 has a condensation medium inlet 5111 and a condensation medium outlet 5112 communicating with the condensation channel. The condensation medium inlet 5111 and the condensation medium outlet 5112 are connected to the outside.

[0045] In this embodiment, the condenser fins 512 are plate-shaped and multiple fins are provided. Each condenser fin 512 is vertically arranged, and adjacent condenser fins 512 are spaced apart. The condenser tube 511 passes through the multiple condenser fins 512 in a serpentine pattern, thereby enabling sufficient condensation of the humid and hot air passing through the condenser fins 512.

[0046] In this embodiment, a water nozzle 53 is connected to the condensate inlet 5111 and the condensate outlet 5112 to facilitate the flow of water to reduce the temperature within the condensation channel. The water nozzle 53 is located outside the housing 1.

[0047] In the flow path of the reducing moisture, an air guide shroud 54 is provided upstream of the condenser 51. In this embodiment, the air guide shroud 54 is located above the condenser 51.

[0048] The air guide shroud 54 has an air guide channel 540 running through it from top to bottom. At least a portion of the condenser 51 is located inside the air guide channel 540. The air guide shroud 54 has an inclined guide surface at the inlet end of the air guide channel 540 that guides the reducing moisture to the condenser 51.

[0049] In other embodiments, the condenser 51 may be circulated with a low-temperature air medium, or the condenser 51 may be a semiconductor condensation device. Example 2

[0050] This application also discloses a dishwasher, as described in the embodiments below. Figure 7 It has a washing chamber 6 and a drying system as described in Embodiment 1 above, the drying system being used to heat and dry the gas in the washing chamber 6.

[0051] Reference Figure 1 and Figure 7The dehumidification channel 1001 has an air inlet 1010 and an air outlet 1016. The washing chamber 6 is connected to the air inlet 1010 of the dehumidification channel 1001 through the air inlet channel 3. The air outlet 1016 of the dehumidification channel 1001 is connected to the washing chamber 6 through the air supply channel 7 and the breather. The gas to be dehumidified in the washing chamber 6 enters the dehumidification channel 1001 from the air inlet 1010 and is dehumidified and dried through the dehumidification zone 101 of the adsorption element 21, so that the dried gas returns to the washing chamber 6 from the air outlet 1016.

[0052] At the same time, the heating component 4 heats and regenerates the reduction zone 102 of the adsorbent 21 and generates reduced moisture. The reduced moisture is condensed by the condensing component 5 to generate regenerated dry gas and returns to the reduction zone 102 of the adsorbent 21, forming a closed reduction and regeneration channel 1002.

[0053] The dehumidification channel 1001 and the reduction and regeneration channel 1002 work simultaneously. The dehumidification zone 101 of the adsorbent 21 dehumidifies and dries the dehumidified gas in the washing cavity 6. The heating component 4 heats the reduction zone 102 of the moisture-saturated adsorbent 21, thereby quickly restoring its moisture absorption capacity and greatly improving the drying efficiency. The adsorbent 21 absorbs moisture and releases heat, and this part of the temperature can provide some heat to the washing cavity 6, thereby achieving energy saving.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
