[0002] For clothing processing equipment using water-cooled drying, the drying system includes a condenser duct and a heating duct. The hot and humid drying airflow enters the condenser duct and comes into direct or indirect contact with the condensate water to complete heat exchange, thus transforming into a dry and cool drying airflow. Then, it enters the heating duct through a fan, where it is transformed into a high-temperature and dry drying airflow under the heating action of the heating element.

Detailed Implementation

[0045] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0047] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0048] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0049] In the existing technology, the structural design of the condenser duct is unreasonable, the heat exchange time between the drying airflow and the condensate is short and the heat exchange area is small, resulting in low condensation efficiency, incomplete dehumidification and long drying time.

[0050] This invention creatively provides a condensation assembly for use in a garment processing device. The garment processing device includes an outer cylinder; the condensation assembly includes a condensation shell and a condensation cover. The condensation shell is formed on the cylinder wall of the outer cylinder, and the condensation cover is provided on the condensation shell, so that the condensation cover, the condensation shell, and the cylinder wall of the outer cylinder form a condensation air duct through which the drying airflow can flow; a condensate chamber is formed inside the condensation cover, and condensate can flow through both the condensate chamber and the condensation air duct.

[0051] The drying airflow can enter the condenser duct and exchange heat with the condensate flowing through the condenser duct and the inner surface of the condenser cover. This increases the heat exchange area between the drying airflow and the condensate, prolongs the heat exchange time, and ensures sufficient heat exchange between the drying airflow and the condensate, thereby improving condensation efficiency, ensuring thorough dehumidification, and shortening the drying time. This solves the problems of unreasonable structural design of the condenser duct in the prior art, which leads to short heat exchange time and small heat exchange area between the drying airflow and the condensate, and also solves the problems of low condensation efficiency and incomplete dehumidification in the prior art.

[0052] Example 1

[0053] <Condensation Duct>

[0054] like Figures 1 to 3 As shown, this embodiment provides a condensation assembly for a garment processing device, which includes an outer cylinder 1. The condensation assembly includes a condensation shell 131 and a condensation cover 132. The condensation shell 131 is formed on the cylinder wall of the outer cylinder 1, and the condensation shell 131 is covered by the condensation cover 132, so that the condensation cover 132, the condensation shell 131, and the cylinder wall of the outer cylinder 1 form a condensation air duct 134 through which the drying airflow can flow. A condensate water chamber is formed inside the condensation cover 132, and condensate water can flow through both the condensate water chamber and the condensation air duct 134. Specifically, the condensation shell 131 and the cylinder wall of the outer cylinder are integrally formed. An open opening is formed on the side of the condensation shell away from the outer cylinder, and the condensation cover 132 is placed on the open opening and closes the open opening, thereby forming a condensation air duct 134 by the cylinder wall of the outer cylinder 1, the condensation shell 131, and the condensation cover 132.

[0055] The condensing air duct 134 includes a condensing air inlet and a condensing air outlet 1344 connected to the condensing air duct 134. The drying airflow can enter the condensing air duct 134 through the condensing air inlet and can be discharged from the condensing air duct 1344 through the condensing air outlet 1344. In view of the problem of low condensing efficiency caused by unreasonable structural design of the condensing cover 132, this embodiment proposes that the end of the condensing cover 132 near the condensing air outlet 1344 forms a condensing water chamber inlet 1353 and a first condensing water chamber outlet 1351. The condensing water chamber inlet 1353 connects the inside of the condensing water chamber 135 and the outside of the condensing water chamber 135, and the first condensing water chamber outlet 1351 connects the inside of the condensing water chamber 135 and the condensing air duct 134.

[0056] The condensate outside the condensate chamber first enters the interior of the condensate chamber through the condensate chamber inlet 1353, and then enters the condensate air duct 134 through the first condensate chamber outlet 1351. When flowing through the condensate air duct 134, it can exchange heat with the drying airflow; thus achieving the purpose of making full use of the condensate and greatly improving the drying efficiency.

[0057] The structure of the condensate chamber 135 is adapted to the structure of the condensate cover 132; a plurality of first condensate chamber outlets 1351 are formed on the inner side of the condensate cover 132, and the plurality of first condensate chamber outlets 1351 are arranged sequentially at intervals along the width direction of the condensate cover 132; the condensate inside the condensate chamber can enter the condensate air duct 134 through the plurality of first condensate chamber outlets 1351.

[0058] To address the issue of low heat exchange efficiency between condensate and drying airflow when condensate flows through the condensing duct, this embodiment proposes that an external guide rib be provided within the condensing duct 134. The external guide rib can be a straight or arc-shaped structure. Multiple external guide ribs are provided, spaced apart and staggered along the length of the condensing duct 134. The position and / or extension direction and / or extension length of the external guide ribs are adjustable. While serving a guiding function, the external guide ribs can also slow down the flow rate of the condensate, increase the heat exchange area between the condensate and drying airflow, improve condensation efficiency, and save condensate. The external guide ribs include multiple... Multiple first external guide ribs 151 are disposed on the inner side of the condenser cover 132, and are arranged sequentially at intervals along the length of the condenser cover 132. The extension direction of each first external guide rib 151 is inclined relative to the vertical direction. After entering the condenser air duct 134, the condensate flows along the inner side of the condenser cover 132 and passes through multiple first external guide ribs 151. On the one hand, the condensate can exchange heat with the condenser cover 132; on the other hand, the condensate can exchange heat with the drying airflow. Both of these heat exchanges are beneficial to reducing the humidity of the drying airflow.

[0059] Furthermore, the position and / or extension direction and / or extension length of the first outer guide rib 151 can be adjusted on the inner side of the condenser cover 132; the position, extension direction and extension length of the first outer guide rib 151 can be adjusted according to actual needs, thereby adjusting the flow rate and flow state of the condensate and improving the heat exchange efficiency between the condensate and the drying airflow.

[0060] In two adjacent first outer guide ribs 151, the water outlet end of the upstream first outer guide rib 151 is close to the water inlet end of the downstream first outer guide rib 151, so that the condensate entering the condensing air duct 134 can flow through multiple first outer guide ribs 151 in sequence; the flow path of the condensate in the condensing air duct 134 is extended, the heat exchange area between the condensate and the drying airflow is increased, and the condensation efficiency is improved.

[0061] To address the issue of poor airflow due to improper placement of the outer guide ribs, this embodiment further proposes that the outer guide ribs include multiple second outer guide ribs 152. These multiple second outer guide ribs 152 are all disposed on the wall of the outer cylinder 1 and are sequentially spaced along the extension length of the condensing air duct 134. The extension direction of each second outer guide rib 152 is inclined relative to the vertical direction. After entering the condensing air duct 134, the condensate flows along the outer side of the wall of the outer cylinder 1 and passes through the multiple second outer guide ribs 152. On the one hand, the condensate can exchange heat with the wall of the outer cylinder 1; on the other hand, the condensate can exchange heat with the drying airflow. Both types of heat exchange are beneficial for reducing the humidity of the drying airflow.

[0062] Furthermore, the position and / or extension direction and / or extension length of the second outer guide rib 152 can be adjusted and set on the inner side of the outer cylinder 1 wall; the position, extension direction and extension length of the second outer guide rib 152 can be adjusted according to actual needs, thereby adjusting the flow rate and flow state of the condensate and improving the heat exchange efficiency between the condensate and the drying airflow.

[0063] In two adjacent second outer guide ribs 152, the water outlet end of the upstream second outer guide rib 152 is close to the water inlet end of the downstream second outer guide rib 152, so that the condensate entering the condensing air duct 134 can flow through multiple second outer guide ribs 152 in sequence; the flow path of the condensate in the condensing air duct 134 is extended, the heat exchange area between the condensate and the drying airflow is increased, and the condensation efficiency is improved.

[0064] To address the problem of poor condensation effect caused by improper positioning of the first and second outer guide ribs 152, this embodiment proposes that multiple first and second outer guide ribs 152 are alternately arranged within the condensation duct 134. Among adjacent first and second outer guide ribs 152, condensate flowing through the upstream first outer guide rib can flow through the downstream second outer guide rib 152. This allows the condensate to flow across the upstream first outer guide rib to the downstream second outer guide rib 152, and then across the upstream second outer guide rib 152 to the downstream first outer guide rib, thus extending the flow path of the condensate, increasing the heat exchange area between the condensate and the drying airflow, ensuring sufficient contact between the condensate and the drying airflow, and improving condensation efficiency.

[0065] The condenser cover 132 is made of sheet metal welded together or aluminum cast in shape; sheet metal and aluminum have low specific heat capacity, making them easier to conduct heat and thus providing better condensation.

[0066] <Drying System>

[0067] The drying system includes a heating air duct and a condensing air duct as described above. The condensing air duct 134 includes a condensing air outlet 1344. One end of the heating air duct is connected to the condensing air outlet 1344 via a drying fan.

[0068] The condensate water inlet and the first condensate water outlet of the condensate duct 134 are both located close to the condensate air outlet 1344.

[0069] <Clothing Processing Equipment>

[0070] like Figure 5As shown, this embodiment provides a garment processing device, including an outer drum 1, an inner drum, and a drying system; the outer drum 1 includes an outer drum peripheral wall 11 and an outer drum rear wall 12; a drying air inlet is formed at the opening of the outer drum, and a drying air outlet is formed on the outer drum rear wall 12, including a first drying air outlet 121 and a second drying air outlet 122, with the first drying air outlet 121 located above the second drying air outlet 122; a condensation zone is formed between the inner side of the outer drum rear wall 12, the inner side of the outer drum peripheral wall 11, and the rear wall of the inner drum, the condensation zone being connected to the first drying air outlet 121 and allowing the drying airflow and condensate to flow through it; the inner drum is rotatably disposed inside the outer drum 1 for carrying garments; a drying air inlet, a first drying air outlet 121, and a second drying air outlet 122 are all provided. The system includes a filter screen to filter lint from the drying airflow; flushing valves are installed at the drying air inlet, the first drying air outlet 121, and the second drying air outlet 122, which can spray water onto the corresponding filter screen to clean it; specifically, a door seal is installed at the opening of the outer cylinder, forming a drying air inlet; the first drying air outlet 121 is located above the horizontal reference plane, and the second drying air outlet 122 is located below the horizontal reference plane, which is a plane passing through the axis of the outer cylinder 1 and parallel to the horizontal plane; the flow area of ​​the first drying air outlet 121 is smaller than the flow area of ​​the second drying air outlet 122; a condenser shell 131 is installed on the outer side 133 of the rear wall of the outer cylinder, and the condenser cover 132, the condenser shell 131, and the rear wall 12 of the outer cylinder form a condenser air duct 134.

[0071] The drying system includes:

[0072] The condensing air duct 134 includes a first condensing air inlet and a second condensing air inlet. The first condensing air inlet is connected to the first drying air outlet 121, and the second condensing air inlet is connected to the second drying air outlet 122. The condensing shell 131 is formed on the outer side 133 of the rear wall of the outer cylinder, reducing the thermal resistance between the rear wall 12 of the outer cylinder and the condensing air duct 134 during drying. The outer cylinder 1, heated by the drying airflow, can maintain and raise the temperature of the drying airflow circulating in the condensing air duct 134, reducing heat loss and achieving faster drying. The condensing shell 131 and the condensing cover 132 are fixed by welding, screws, or clips. The condensing shell 131 and the condensing cover 132 are sealed together to prevent water leakage from the condensing air duct 134. The condensing air duct 134 includes a first condensing section 1341, a second condensing section 1342, and an air outlet section 1343. One end of a condensing section 1341 forms a first condensing air inlet, which is connected to a first drying air outlet 121. The other end of a second condensing section 1342 forms a second condensing air inlet, which is connected to a second drying air outlet 122. The other end of the first condensing section 1341 is connected to the other end of the second condensing section 1342. An air outlet section 1343 is located at the connection between the first condensing section 1341 and the second condensing section 1342, and one end of the air outlet section 1343 is connected to both the first condensing section 1341 and the second condensing section 1342. The other end of the air outlet section 1343 forms a condensing air outlet 1344. Both the first condensing section 1341 and the second condensing section 1342 have an arc-shaped structure, and the flow area of ​​the first condensing section 1341 is smaller than the flow area of ​​the second condensing section 1342.

[0073] The heating air duct has its end furthest from the condensing air duct 134 connected to the drying air inlet. The inner side of the rear wall 12 of the outer cylinder serves as the first condensing surface, through which condensate water flows. A portion of the drying airflow inside the outer cylinder 1 exchanges heat with the condensate water flowing along the first condensing surface, and then enters the first condensing section through the first drying air outlet 121. The inner side of the condensing cover serves as the second condensing surface, through which condensate water flows. Another portion of the drying airflow inside the outer cylinder 1 can enter the condensing air duct 134 through the second drying air outlet 122 and exchange heat with the condensate water flowing along the second condensing surface, and then exit through the condensing air outlet. The airflow enters the heating duct through inlet 1344; this expands the heat exchange area between the drying airflow and the condensate, allowing for full contact between the two, improving the condensation effect, and shortening the drying time; a heating device is installed inside the heating duct to heat the drying airflow flowing through it; the outer cylinder 1, inner cylinder, condensate duct 134, drying fan, and heating duct constitute a drying airflow loop, with the drying fan providing power to the drying airflow, causing it to circulate within the loop; specifically, the heating device is an electric heating element; the drying airflow in the heating duct enters the inner cylinder through the drying air inlet.

[0074] Both the first drying air outlet 121 and the second drying air outlet 122 can be independently controlled to open or close. Depending on actual drying needs, the first drying air outlet 121 can be opened and the second drying air outlet 122 closed, allowing the drying airflow inside the outer cylinder 1 to enter the condenser duct 134 via the inner side of the outer cylinder rear wall 12 and the first drying air outlet 121; or the second drying air outlet 122 can be opened and the first drying air outlet 121 closed, allowing the drying airflow inside the outer cylinder 1 to enter the condenser duct 134 via the second drying air outlet 122; or both the first and second drying air outlets 122 can be opened, allowing a portion of the drying airflow inside the outer cylinder 1 to enter the condenser duct 134 via the inner side of the outer cylinder rear wall 12 and the first drying air outlet 121, while another portion of the drying airflow inside the outer cylinder 1 enters the condenser duct 134 via the second drying air outlet 122.

[0075] Furthermore, a condenser inner water inlet valve 141 is provided at one end of the outer cylinder peripheral wall 11 near the rear wall of the outer cylinder. The condenser inner water inlet valve 141 is connected to the outer cylinder 1, and the condensate from the outside can enter the outer cylinder 1 through the condenser inner water inlet valve 141 and flow along the first condensation surface. A condenser outer water inlet valve 142 is provided at the condensate water inlet 1353, and the condensate from the outside can enter the condensate water chamber through the condenser outer water inlet valve 142. The condensate water enters the condensation air duct 134 and can flow along the second condensation surface. A portion of the condensate water can enter the outer cylinder 1 through the condenser inner water inlet valve 141 and flow from top to bottom along the first condensation surface and exchange heat with the drying airflow flowing through the inner side of the rear wall 12 of the outer cylinder. Another portion of the condensate water can first enter the condensate water chamber through the condenser outer water inlet valve 142, and then enter the condensation air duct 134 through the outlet 1351 of the first condensate water chamber, and flow from top to bottom along the second condensation surface and exchange heat with the drying airflow in the condensation air duct 134.

[0076] Multiple first drying air outlets 121 are sequentially arranged along the extension direction of the first condensation section, and each first drying air outlet 121 can be independently controlled to open or close; multiple second drying air outlets 122 are sequentially arranged along the extension direction of the second condensation section, and each second drying air outlet 122 can be independently controlled to open or close; according to the actual drying needs, the corresponding number and position of the first drying air outlets 121 and second drying air outlets 122 can be opened, so that the drying airflow in the outer cylinder 1 enters the condensation air duct 134 through the first drying air outlets 121 and second drying air outlets 122 respectively, thereby extending the flow path of the drying airflow, increasing the heat exchange area between the drying airflow and the condensate, and improving the condensation efficiency.

[0077] In addition, multiple inner guide ribs are provided on the inner side of the outer cylinder rear wall 12. The multiple inner guide ribs are spaced apart on the inner side of the outer cylinder rear wall 12, and the extension direction of each inner guide rib is inclined relative to the vertical direction; the position and / or extension direction and / or extension length of the inner guide ribs can be adjusted.

[0078] When condensate flows through the inner guide ribs, it can prolong the heat exchange time and heat exchange area between the condensate and the drying airflow, thereby improving the condensation effect.

[0079] In summary, this embodiment designs a condensate chamber inside the condenser cover 132. The condenser cover 132, the condenser shell 131, and the outer cylinder 1 form a condensation duct 134. The condensate outside the condensate chamber first enters the interior of the condensate chamber and then enters the condensation duct 134. The drying airflow can enter the condensation duct 134 and exchange heat with the condensate flowing through the condensation duct 134 and the inner surface of the condenser cover 132. By making full use of the condensate, the heat exchange area between the drying airflow and the condensate is increased, the condensation efficiency is improved, and the problem of short heat exchange time and small heat exchange area between the drying airflow and the condensate caused by the unreasonable structural design of the condensation duct in the prior art is solved.

[0080] Multiple first outer guide ribs 151 are provided on the inner side of the condenser cover 132, and multiple second outer guide ribs 152 are provided on the rear wall 12 of the outer cylinder. On the one hand, the condensate can exchange heat with the condenser cover 132 or the rear wall 12 of the outer cylinder; on the other hand, the condensate can exchange heat with the drying airflow. Both of these heat exchanges are beneficial to reducing the humidity of the drying airflow.

[0081] In addition, both the outer and inner sides of the rear wall 12 of the outer cylinder are used as condensation surfaces, which expands the heat exchange area between the drying airflow and the condensate, allowing the drying airflow and the condensate to come into full contact.

[0082] <Drying Control Methods>

[0083] like Figure 6 As shown, this embodiment also provides a drying control method for a garment processing device, wherein the garment processing device is any of the garment processing devices described above, and the garment processing device is provided with a drying process; when the garment processing device operates the drying process, the drying control method includes:

[0084] S1. Obtain the current temperature of the drying airflow inside the outer cylinder 1;

[0085] S2. Determine if the current temperature is greater than the preset temperature;

[0086] S3. Control the condensate to enter the condensate chamber based on whether the current temperature is greater than the preset temperature.

[0087] Furthermore, S3 includes:

[0088] Determine if the current temperature is greater than the first preset temperature;

[0089] When the current temperature is greater than or equal to the first preset temperature, the condensate enters the condensate chamber 135 at a first flow rate;

[0090] With the condensate chamber 135 filled with condensate, the condensate enters the condensate chamber 135 at a second flow rate;

[0091] Wherein, the first flow rate Q1 is greater than the second flow rate Q2, and 0.5 / min≤Q1≤2L / min; the first preset temperature is 60℃. When the temperature of the drying airflow reaches 60℃, the moisture in the clothes in the inner drum has been fully heated into water vapor. The condensate enters the condensate chamber 135 at the first flow rate, which quickly cools the condensate cover 132. At this time, the water inlet is large, and the condensate chamber 135 is quickly filled. The condensate flows out from the outlet 1351 of the first condensate chamber. The outflowing condensate can come into contact with the drying airflow, causing the moisture in the drying airflow to liquefy upon cooling. At the same time, because there is condensate in the condensate chamber 135, the condensate can cool the condensate cover 132. Therefore, when the drying airflow comes into contact with the condensate cover 132, it can also liquefy and precipitate moisture. In this way, the "double condensation" effect is achieved, improving the condensation efficiency and shortening the drying time.

[0092] The heating duct is equipped with heating equipment; S3 also includes:

[0093] Continue to determine whether the current temperature is greater than the second preset temperature;

[0094] When the current temperature is less than or equal to the second preset temperature, the condensate water is stopped from entering the condensate water chamber and the heating equipment is put into operation.

[0095] Continue to determine whether the current temperature is greater than the third preset temperature;

[0096] When the current temperature is greater than or equal to the third preset temperature, condensate will continue to enter the condensate chamber and the heating equipment will be stopped.

[0097] The second preset temperature is less than the first preset temperature and the third preset temperature; the second preset temperature is 50℃ and the third preset temperature is 65℃.

[0098] In this embodiment, the condensate water entering the condensate water chamber is precisely controlled based on whether the current temperature is greater than a preset temperature. The condensate water enters the condensate water chamber 135 at a first flow rate, rapidly cooling the condenser cover 132. The condensate water enters the condensate water chamber 135 at a second flow rate to prevent the condensate water in the condensate water chamber 135 from overflowing. When the current temperature is less than or equal to a second preset temperature, the condensate water entering the condensate water chamber is stopped and the heating device is in operation, rapidly heating the drying airflow. When the current temperature is greater than or equal to a third preset temperature, the condensate water continues to enter the condensate water chamber and the heating device is stopped, rapidly dehumidifying the drying airflow. This solves the problems in the prior art where the condensate water control method is poorly designed and has low precision, resulting in poor condensation effect and excessively high or low temperatures in the drying airflow.

[0099] Example 2

[0100] like Figure 4 As shown, unlike Embodiment 1, the inner surface of the condenser cover 132 is formed with multiple second condensate outlet groups. Each second condensate outlet group includes multiple second condensate outlets 1352, which connect the condensate chamber 135 and the condensate duct 134. The multiple second condensate outlet groups are correspondingly arranged with multiple first external guide ribs. The condensate in the condensate chamber can enter the condensate duct 134 through the multiple second condensate outlets 1352 and flow through the corresponding first external guide ribs, so that the condensate can fully contact the drying airflow and improve the heat exchange efficiency between the condensate and the drying airflow. The multiple second condensate outlets 1352 can be controlled to open or close independently. According to actual needs, the corresponding second condensate outlets 1352 can be opened to achieve different condensation effects.

[0101] Furthermore, the diameter of the first condensate outlet 1351 is d1, and the diameter of the second condensate outlet 1352 is d2, satisfying: d1>d2, 2mm≤d1≤15mm, 1.5mm≤d2≤10mm; so that most of the condensate in the condensate chamber can be discharged through the first condensate outlet 1351 and flow along the second condensation surface, and most of the condensate in the condensate chamber can be discharged through the second condensate outlet 1352 and flow along the first outer guide rib.

[0102] In this embodiment, the condensate in the condensate chamber can enter the condensate air duct 134 through multiple second condensate chamber outlets 1352 and flow through the corresponding first outer guide ribs 151, so that the condensate can fully contact the drying airflow and improve the heat exchange efficiency between the condensate and the drying airflow; thus solving the problem of insufficient contact between the condensate and the drying airflow, low condensate utilization rate and poor condensation effect caused by the unreasonable structural design of the condensate cover.

[0103] Example 3

[0104] Unlike Embodiment 1, each of the first outer guide ribs has a first guide groove and a first drip hole. The extension direction of the first guide groove is consistent with the extension direction of the first outer guide rib. The first drip hole is close to the inner side of the condenser cap 132 and there are multiple first drip holes. The multiple first drip holes are arranged sequentially along the extension direction of the first guide groove and each first drip hole is connected to the first guide groove.

[0105] In the two adjacent first outer guide ribs, the condensate in the upstream first guide groove can be discharged through the corresponding first drip hole and flow along the first transition surface to the downstream first guide groove;

[0106] The first transition surface is the portion of the inner side of the condenser cap 132 between two adjacent first outer guide ribs.

[0107] Each second outer guide rib 152 has a second guide groove and a second drip hole. The extension direction of the second guide groove is consistent with the extension direction of the second outer guide rib 152. The second drip hole is close to the outer side of the rear wall 12 of the outer cylinder and multiple second drip holes are provided. Multiple second drip holes are arranged sequentially along the extension direction of the second guide groove and each second drip hole is connected to the second guide groove.

[0108] In two adjacent second outer guide ribs 152, the condensate in the upstream second guide groove can be discharged through the corresponding second drip hole and flow along the second transition surface to the downstream second guide groove;

[0109] The second transition surface is the portion of the outer side of the outer cylinder rear wall 12 between two adjacent second outer guide ribs 152.

[0110] In this embodiment, the condensate in the first guide channel is diverted and discharged through each first drip hole and flows along the first transition surface, and the condensate in the second guide channel is diverted and discharged through each second drip hole and flows along the second transition surface. On the one hand, this reduces the flow rate of the condensate, and on the other hand, it expands the flow area of ​​the condensate, allowing the condensate and the drying airflow to fully contact each other, making full use of the condensate for dehumidification, and solving the problems of excessive condensate flow rate and small contact area between the condensate and the drying airflow, which lead to poor condensation effect.
