Description

Technical Field

[0001] This invention belongs to the field of clothing processing technology, and in particular relates to a clothing processing device. Background Technology

[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. The drying airflow enters the outer drum and exchanges heat with the clothes inside the inner drum to achieve the drying of the clothes. In the existing technology, the structural design of the condenser duct is unreasonable, the contact between the drying airflow and the condensate water is insufficient, and the heat exchange time between the drying airflow and the condensate water is short, resulting in low condensation efficiency, incomplete dehumidification, and long drying time. Summary of the Invention

[0005] The condensing air duct includes a condensing air inlet and a condensing air outlet, wherein the condensing air inlet is connected to the air outlet of the outer cylinder; the condensing air duct is formed by a condensing shell disposed on the outer side of the rear wall of the outer cylinder and a condensing cover disposed on the condensing shell; the condensing air duct forms a necked section between the condensing air inlet and the condensing air outlet.

[0006] The heating air duct is connected at one end to the drying air inlet and at the other end to the condenser air outlet via a drying fan.

[0007] Further optionally, the condenser shell includes two opposing condenser shell walls, one of which protrudes into the other to form a protrusion, and the protrusion, the condenser cover, the other condenser shell wall, and the outer side of the rear wall of the outer cylinder surround the necked section.

[0008] Further optionally, the protrusion is an arc-shaped structure or a wedge-shaped structure;

[0009] When the protrusion is a wedge-shaped structure, the protrusion includes a first protruding edge and a second protruding edge, and the angle between the first protruding edge and the second protruding edge is α, which satisfies: 80°≤α≤150°.

[0010] Further optionally, the minimum distance between the protrusion and the other condensation shell wall is s0, satisfying: 20mm≤s0≤60mm.

[0011] Further optionally, the highest point of the protrusion is higher than the axis of the outer cylinder, the lowest point of the protrusion is lower than the axis of the outer cylinder, and the distance between the highest and lowest points of the protrusion is s12, satisfying: 40mm≤s12≤80mm.

[0012] Alternatively, the condensing air duct is provided with a plurality of external guide ribs, which are arranged sequentially at intervals and in parallel staggered arrangement along the length of the condensing air duct.

[0013] Alternatively, a water-retaining rib is provided in the constricted section, and the water-retaining rib forms a water-retaining cavity, which can store condensate flowing through the constricted section.

[0014] Alternatively, the water-retaining rib is rotatably disposed within the constricted section; under the action of condensate in the water-retaining cavity, the water-retaining rib can rotate and cause the water-retaining cavity to discharge condensate.

[0015] Further optionally, the outer cylinder air outlet includes a first outer cylinder air outlet and a second outer cylinder air outlet, the first outer cylinder air outlet being located above the second outer cylinder air outlet; the condensate air outlet is located between the first outer cylinder air outlet and the second outer cylinder air outlet;

[0016] The diameter of the air outlet of the first outer cylinder is d1, and the diameter of the air outlet of the second outer cylinder is d2, satisfying: 18mm≤d1≤35mm, 35mm≤d2≤50mm.

[0017] Further optionally, condensate can flow through the inner side of the rear wall of the outer cylinder, and the outer side of the rear wall of the outer cylinder is integrally formed with the condensate shell;

[0018] A portion of the drying airflow inside the outer cylinder can flow along the inner side and exchange heat with the condensate flowing through the inner side, and then enter the condensation duct through the first outer cylinder air outlet; another portion of the drying airflow inside the outer cylinder can enter the condensation duct through the second outer cylinder air outlet and exchange heat with the condensate flowing through the condensation duct.

[0019] Compared with the prior art, the main advantages of the present invention are as follows:

[0020] An air inlet is formed at the opening of the outer cylinder, and an air outlet is formed on the rear wall of the outer cylinder. The condenser air inlet is connected to the outer cylinder air outlet, and the heating air duct is connected to the condenser air outlet and the outer cylinder air inlet. A constricted section is formed between the condenser air inlet and the condenser air outlet in the condenser air duct. When the drying airflow passes through the constricted section, the flow velocity increases, and it comes into contact with the condensate flowing through the constricted section, causing the condensate to suspend at the constricted section. When the drying airflow enters the upper side of the constricted section, the flow velocity decreases, so the condensate will not re-enter the upper side of the constricted section, allowing the drying airflow and condensate to fully contact, prolonging the heat exchange time between the drying airflow and condensate, improving condensation efficiency, thoroughly dehumidifying, and shortening the drying time. This solves the problem of unreasonable structural design of the condenser air duct in the prior art, which leads to short heat exchange time and insufficient contact between the drying airflow and condensate, and solves the problems of low condensation efficiency and incomplete dehumidification in the prior art.

Detailed Implementation

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] In the existing technology, the structural design of the condenser duct is unreasonable, the contact between the drying airflow and the condensate is insufficient, and the heat exchange time between the drying airflow and the condensate is short, resulting in low condensation efficiency, incomplete dehumidification and long drying time.

[0033] This invention creatively provides a garment processing device, including an outer drum and a drying system. The outer drum includes a rear wall; a drying air inlet is formed at the opening of the outer drum, and an air outlet is formed on the rear wall of the outer drum; the drying system includes a condensing air duct and a heating air duct, the condensing air duct including a condensing air inlet and a condensing air outlet, the condensing air inlet being connected to the air outlet of the outer drum; the condensing air duct is surrounded by a condensing shell and a condensing cover; the condensing air duct has a constricted section; the heating air duct connects the drying air inlet and the condensing air outlet.

[0034] When the drying airflow passes through the constricted section, its velocity increases, contacting the condensate flowing through the constricted section and suspending the condensate there. As the drying airflow enters the upper part of the constricted section, its velocity decreases, preventing the condensate from re-entering the upper part of the constricted section. This ensures sufficient contact between the drying airflow and the condensate, prolonging the heat exchange time between them, improving condensation efficiency, ensuring thorough dehumidification, and shortening the drying time. This solves the problems of short heat exchange time and insufficient contact between the drying airflow and condensate caused by unreasonable structural design of the condenser duct in existing technologies, and also addresses the issues of low condensation efficiency and incomplete dehumidification in existing condenser ducts.

[0035] Example 1

[0036] like Figures 1 to 4 As 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 an outer drum air outlet is formed on the outer drum rear wall 12, the outer drum air outlet including a first outer drum air outlet 121 and a second outer drum air outlet 122; the first outer drum air outlet 121 is located above the second outer drum air outlet 122; specifically, the first outer drum air outlet 121 can be aligned with or staggered from the second outer drum air outlet 122;

[0037] The inner drum is rotatably mounted inside the outer drum 1 to hold clothing. Filters are installed at the drying air inlet, the first outer drum air outlet 121, and the second outer drum air outlet 122 to filter lint from the drying airflow. A flushing valve is also installed at the drying air inlet, the first outer drum air outlet 121, and the second outer drum air outlet 122 to spray water onto the corresponding filter and clean it. Specifically, a door seal is installed at the opening of the outer drum, forming a drying air inlet. The first outer drum air outlet 121 is located above the reference plane, and the second outer drum air outlet 122 is located below the reference plane. The flow area of ​​the first outer drum air outlet 121 is smaller than the flow area of ​​the second outer drum air outlet 122. The reference plane is a plane passing through the axis of the outer drum and parallel to the horizontal plane.

[0038] The drying system includes:

[0039] The condenser duct 133 includes a condenser inlet and a condenser outlet 134. The condenser inlet includes a first condenser inlet and a second condenser inlet. The first condenser inlet is connected to the first outer cylinder outlet 121, and the second condenser inlet is connected to the second outer cylinder outlet 122. The condenser duct 133 is disposed on the outer side of the rear wall 12 of the outer cylinder and includes a condenser shell 131 and a condenser cover 132 covering the condenser shell 131. A condensing air duct 133 is formed between the outer cylinder and the second outer cylinder; the condensing air outlet 134 is located between the first outer cylinder outlet 121 and the second outer cylinder outlet 122, and the condensing air outlet 134 is close to the first outer cylinder outlet 121; a necked section 135 is formed between the condensing air inlet and the condensing air outlet 134 in the condensing air duct 133, and the necked section 135 is a necked structure; specifically, the condensing air duct 133 is integrally injection molded with the rear wall 12 of the outer cylinder to reduce the heat of the rear wall 12 of the outer cylinder and the condensing air duct 133 during drying. The outer cylinder 1, heated by the drying airflow, can maintain and raise the temperature of the drying airflow circulating in the condenser duct 133, reducing heat loss and achieving faster drying. The condenser shell 131 and the condenser cover 132 are fixed by welding, screws, or clips. The condenser shell 131 and the condenser cover 132 are sealed together to prevent water leakage from the condenser duct 133. An external guide rib 151 is provided inside the condenser duct 133. The external guide rib 151 can be a straight structure or an arc structure. The external guide rib 151 is set with... There are multiple external guide ribs 151 arranged sequentially and alternately in parallel along the length of the condensing air duct 133; the position and / or extension direction and / or extension length of the external guide ribs 151 can be adjusted. For example, if the external guide ribs 151 can be slidably set, the position of the external guide ribs 151 can be adjusted; if the external guide ribs 151 can be rotated, the extension direction of the external guide ribs 151 can be adjusted; if the external guide ribs 151 are made of a stretchable material, the extension length of the external guide ribs 151 can be adjusted.

[0040] A heating air duct is connected at one end to the drying air inlet and at the other end to the condenser air outlet 134 via a drying fan. The inner side of the rear wall 12 of the outer cylinder serves as a condensation surface through which condensate flows. A portion of the drying airflow inside the outer cylinder 1 flows along the inner side of the rear wall 12 and exchanges heat with the condensate flowing through the condensation surface before entering the condenser air duct 133 through the first outer cylinder air outlet 121. Condensate flows through the condenser air duct 133, and another portion of the drying airflow inside the outer cylinder 1 enters the condenser air duct 133 through the second outer cylinder air outlet 122 and exchanges heat with the condensate flowing through it. This expands the drying capacity. The heat exchange area between the airflow and the condensate ensures full contact between the drying airflow and the condensate, improving the condensation effect and shortening the drying time. The drying airflow in the condensation duct 133 can enter the heating duct through the condensation outlet 134. The heating duct is equipped with heating equipment to heat the drying airflow flowing through it. The outer cylinder 1, inner cylinder, condensation duct 133, drying fan, and heating duct constitute a drying airflow loop. The drying fan provides power to the drying airflow, causing it to circulate within the loop. Specifically, the heating equipment is an electric heating element. The drying airflow in the heating duct enters the inner cylinder through the drying inlet.

[0041] In this embodiment, the condenser duct includes a constriction section 135. When the drying airflow passes through the constriction section 135, the flow velocity increases, and it comes into contact with the condensate flowing through the constriction section 135, causing the condensate to suspend at the constriction section 135. This ensures that the drying airflow and the condensate come into full contact, resulting in thorough dehumidification, extending the heat exchange time between the drying airflow and the condensate, improving condensation efficiency, and saving condensate.

[0042] A condenser 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 inlet valve 141 is connected to the outer cylinder 1, and external condensate can enter the outer cylinder 1 through the condenser inlet valve 141. A condenser outlet valve 142 is provided on the side wall of the condenser shell 131, and external condensate can enter the condenser duct 133 through the condenser outlet valve 142.

[0043] A portion of the condensate can enter the outer cylinder 1 through the inner condensate inlet valve 141 and flow from top to bottom along the inner side of the outer cylinder rear wall 12, exchanging heat with the drying airflow flowing through the inner side of the outer cylinder rear wall 12; another portion of the condensate can enter the condensate duct 133 through the outer condensate inlet valve 142 and flow from top to bottom along the outer guide ribs, exchanging heat with the drying airflow in the condensate duct 133; the outer guide ribs play a guiding role while slowing down the flow rate of the condensate, increasing the heat exchange area between the condensate and the drying airflow, improving the condensation efficiency, and saving condensate;

[0044] Both the first outer cylinder air outlet 121 and the second outer cylinder air outlet 122 can be independently controlled to open or close. Depending on the actual drying needs, the first outer cylinder air outlet 121 can be opened and the second outer cylinder air outlet 122 can be closed, allowing the drying airflow inside the outer cylinder 1 to enter the condensing air duct 133 through the inner side of the outer cylinder rear wall 12 and the first outer cylinder air outlet 121; or the second outer cylinder air outlet 122 can be opened and the first outer cylinder air outlet 121 can be closed, allowing the drying airflow inside the outer cylinder 1 to enter the condensing air duct 133 through the second outer cylinder air outlet 122; or both the first outer cylinder air outlet 121 and the second outer cylinder air outlet 122 can be opened, allowing a portion of the drying airflow inside the outer cylinder 1 to enter the condensing air duct 133 through the inner side of the outer cylinder rear wall 12 and the first outer cylinder air outlet 121, while another portion of the drying airflow inside the outer cylinder 1 enters the condensing air duct 133 through the second outer cylinder air outlet 122.

[0045] To address the problem of low condensation efficiency caused by the unreasonable structural design of the necked section 135, this embodiment proposes that the condenser shell 131 includes two condenser shell walls arranged opposite to each other, with one condenser shell wall protruding towards the other condenser shell wall to form a protrusion 1351. The protrusion 1351, the condenser cover 132, the other condenser shell wall, and the outer side of the outer cylinder rear wall 12 surround the necked section 135. Specifically, the condenser shell 131 includes a left condenser shell wall and a right condenser shell wall arranged opposite to each other along the outer cylinder rear wall 12, with the left condenser shell wall protruding towards the right condenser shell wall to form a protrusion 1351.

[0046] Furthermore, the protrusion 1351 is an arc-shaped structure or a wedge-shaped structure, and the protrusion 1351 protrudes from the left wall of the condenser shell to the right wall of the condenser shell; when the protrusion 1351 is a wedge-shaped structure, the protrusion 1351 includes a first protruding edge and a second protruding edge arranged opposite each other, and the included angle between the first protruding edge and the second protruding edge is α, which satisfies: 80°≤α≤150°.

[0047] In addition, the minimum distance between the protrusion 1351 and the other condenser shell wall is s0, which satisfies: 20mm≤s0≤60mm; so that when the drying airflow flows through the constriction section 135, it comes into contact with the condensate and acts on the condensate, so that the condensate is suspended in the constriction section 135, thus prolonging the heat exchange time between the drying airflow and the condensate.

[0048] To address the issue of low condensation efficiency caused by the improper positioning of the necking section 135, this embodiment proposes that the highest point of the protrusion 1351 is higher than the axis of the outer cylinder 1, and the lowest point of the protrusion 1351 is lower than the axis of the outer cylinder 1. The distance between the highest and lowest points of the protrusion 1351 is s12, satisfying: 40mm ≤ s12 ≤ 80mm. Specifically, the protrusion 1351 is positioned between the first reference surface 161 and the second reference surface 162. Both the first reference surface 161 and the second reference surface 162 are parallel to the reference surface, and the first reference surface 161 is located above the reference surface 163. The distance between the first reference surface 161 and the reference surface 163 is s1; the second reference surface 162 is located below the reference surface 163 and the distance between the second reference surface 162 and the reference surface 163 is s2; satisfying: 50mm≤s1≤70mm, 110mm≤s2≤130mm; wherein, the reference surface 163 is a surface that passes through the axis of the outer cylinder 1 and is parallel to the horizontal plane; the position of the necking section 1351 is optimized so that the drying airflow can smoothly enter the condenser air duct 133, and at the same time, it can stay in the condenser air duct 133 for a certain period of time and fully exchange heat with the condensate water.

[0049] In addition, a water-storing rib 152 is provided inside the constricted section 135, forming a water-storing cavity with its opening facing upwards. The water-storing cavity can temporarily store the condensate flowing through the constricted section 135, further extending the heat exchange time between the drying airflow and the condensate, allowing the drying airflow and the condensate to fully contact each other and achieve the effect of fully utilizing the condensate. The size of the water-storing rib 152 can further limit the flow rate of the drying airflow and enhance the suspension effect of the condensate, for example, the height of the water-storing rib 152. Experimental tests have shown that when the condensate is suspended, it forms a water curtain, and the condensate is continuously drawn out of the area where the drying airflow flows rapidly and enters the area where the drying airflow flows slowly. As the flow rate of the drying airflow slows down, the condensate falls back into the area where the drying airflow flows rapidly until the condensate accumulates and its weight increases. The area where the drying airflow flows rapidly can no longer support the suspension of the condensate, and then the condensate falls and is discharged from the outer cylinder.

[0050] Specifically, the water-retaining rib 152 has an arc-shaped structure or a V-shaped structure; when the water-retaining rib 152 has a V-shaped structure, the water-retaining rib 152 includes a first water-retaining rib edge and a second water-retaining rib edge, the included angle between the first water-retaining rib edge and the second water-retaining rib edge is β, which satisfies: 60°≤β≤180°; the thickness of the water-retaining rib 152 is h, which satisfies: 5mm≤h≤12mm.

[0051] When the condensate in the water storage chamber reaches a certain amount, it can be discharged. To address the problem that the condensate in the water storage chamber will reduce the condensation efficiency if it is not discharged in time, this embodiment proposes that the water storage rib 152 be rotatably set in the necked section 135. Under the action of the condensate in the water storage chamber, the water storage rib 152 can rotate and make the water storage chamber discharge the condensate in time. By alternately storing and discharging condensate in the water storage chamber, the condensation effect is improved.

[0052] To address the problem of low drying efficiency caused by the unreasonable structural design of the first outer cylinder air outlet 121 and the second outer cylinder air outlet 122, this embodiment proposes that the diameter of the first outer cylinder air outlet 121 be d1 and the diameter of the second outer cylinder air outlet 122 be d2, satisfying: 18mm≤d1≤35mm, 35mm≤d2≤50mm. In this way, most of the drying airflow enters the condenser duct 133 through the second outer cylinder air outlet 122, while a small portion of the drying airflow enters the condenser duct 133 through the first outer cylinder air outlet 121, thereby increasing the heat exchange area between the drying airflow and the condensate and improving the condensation effect.

[0053] The extension length of the outer guide rib 151 is L, 20mm≤L≤100mm; the condensate entering the condensing air duct 133 can flow along the outer guide rib 151, which extends the flow path of the condensate and expands the heat exchange area between the condensate and the drying airflow; the outer guide ribs 151 are arranged in parallel and staggered manner, and when the drying airflow flows through the condensing air duct 133, the outer guide ribs 151 can block the lint, and the lint can fall down with the condensate flowing along the outer guide rib 151 and finally be discharged from the outer cylinder 1; this can prevent lint from entering the drying fan and ensure the reliable operation of the drying fan;

[0054] The outer guide rib 151 has multiple through holes, which are arranged sequentially at intervals along the length of the outer guide rib 151. When the drying airflow flows through the through holes, the lint can be trapped by the through holes, thus achieving the effect of removing lint.

[0055] To address the problem of poor airflow due to improper placement of the external guide ribs, this embodiment proposes that the external guide ribs 151 include multiple first external guide ribs 151, all of which are disposed on the condenser cover 132 and are spaced apart sequentially along the length of the condenser cover 132, extending horizontally. After entering the condenser duct 133, the condensate flows along the inner side of the condenser cover 132 and passes through the 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 types of heat exchange are beneficial for reducing the humidity of the drying airflow.

[0056] Furthermore, the position and / or extension direction and / or extension length of the first outer guide rib 151 can be adjusted on 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.

[0057] 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 133 can flow through multiple first outer guide ribs 151 in sequence; the flow path of the condensate in the condensing air duct 133 is extended, the heat exchange area between the condensate and the drying airflow is increased, and the condensation efficiency is improved.

[0058] 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 outer surface of the outer cylinder rear wall 12 and are sequentially spaced along the length of the condenser shell 131, extending horizontally. After entering the condenser duct 133, the condensate flows along the outer surface of the outer cylinder rear wall 12 and passes through the multiple second outer guide ribs 152. On one hand, the condensate can exchange heat with the outer cylinder rear wall 12; 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.

[0059] 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 outer side of the rear wall 12 of the outer cylinder; 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.

[0060] 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 133 can flow through multiple second outer guide ribs 152 in sequence; the flow path of the condensate in the condensing air duct 133 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 problem of poor condensation effect caused by unreasonable structural design of the condensing duct 133, this embodiment proposes that the condensing duct 133 includes a first condensing duct 1331 and a second condensing duct 1332. One end of the first condensing duct 1331 is connected to the air outlet 121 of the first outer cylinder, and one end of the second condensing duct 1332 is connected to the air outlet 122 of the second outer cylinder. The other ends of the first condensing duct 1331 and the second condensing duct 1332 are connected. Both the first condensing duct 1331 and the second condensing duct 1332 have an arc-shaped structure, and the flow area of ​​the first condensing duct 1331 is smaller than the flow area of ​​the second condensing duct 1332.

[0062] Multiple first outer cylinder air outlets 121 are sequentially arranged along the extension direction of the first condensing air duct 1331, and each first outer cylinder air outlet 121 can be independently controlled to open or close; multiple second outer cylinder air outlets 122 are sequentially arranged along the extension direction of the second condensing air duct 1332, and each second outer cylinder air outlet 122 can be independently controlled to open or close; according to the actual drying needs, the corresponding number and corresponding positions of the first outer cylinder air outlets 121 and second outer cylinder air outlets 122 can be opened, so that the drying airflow in the outer cylinder 1 enters the condensing air duct 133 through the first outer cylinder air outlets 121 and the second outer cylinder 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.

[0063] 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 multiple inner guide ribs are inclined in the vertical direction. The position and / or extension direction and / or extension length of the inner guide ribs can be adjusted.

[0064] 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.

[0065] In summary, the condenser duct 133 of this application is integrally injection molded with the rear wall 12 of the outer cylinder, reducing the thermal resistance of the rear wall 12 and the condenser duct 133 during drying. The outer cylinder 1, heated by the drying airflow, can maintain and raise the temperature of the drying airflow circulating in the condenser duct 133, reducing heat loss and achieving rapid drying. Both the outer and inner surfaces of the rear wall 12 of the outer cylinder are used as condensation surfaces, expanding the heat exchange area between the drying airflow and the condensate, allowing for full contact between the drying airflow and the condensate. Furthermore, the condenser duct 133 is designed with a constricted section 135, increasing the flow velocity of the drying airflow as it passes through the constricted section 135, thus improving its efficiency. The condensate in the constricted section 135 comes into contact with and is suspended there, prolonging the heat exchange time between the drying airflow and the condensate, improving the condensation effect, and shortening the drying time. Both the outer guide rib 151 and the inner guide rib can trap some of the lint in the drying airflow. At the same time, condensate remains on the outer guide rib 151 and the inner guide rib, and the lint will fall with the condensate and eventually be discharged outside the outer cylinder 1, achieving the purpose of removing lint from the drying airflow. In addition, the water-retaining rib can assist in suspending the condensate, further prolonging the heat exchange time between the condensate and the drying airflow, making full use of the condensate to improve the condensation effect.

[0066] Example 2

[0067] 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.

[0068] 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;

[0069] The first transition surface is the portion of the inner side of the condenser cap 132 between two adjacent first outer guide ribs.

[0070] Each of the second outer guide ribs 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. The second drip hole is close to the outer side of the rear wall 12 of the outer cylinder and there are multiple second drip holes. 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.

[0071] In two adjacent second outer guide ribs, 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;

[0072] The second transition surface is the portion of the outer side surface of the outer cylinder rear wall 12 between two adjacent second outer guide ribs;

[0073] In this embodiment, the condensate is diverted and discharged through each of the first drip holes and flows along the first transition surface. The condensate is also diverted and discharged through each of the second drip holes and flows along the second transition surface. This reduces the flow rate of the condensate and increases the flow area of ​​the condensate, allowing the condensate and the drying airflow to fully contact each other and making full use of the condensate for dehumidification. This solves the problems of excessive condensate flow rate and poor condensation effect caused by small contact area between the condensate and the drying airflow.

[0074] Example 3

[0075] Unlike Embodiment 1, the bottom wall of the water storage cavity is formed with a water storage cavity drip hole, through which the condensate in the water storage cavity can drip downstream and flow along the downstream outer guide rib;

[0076] In this embodiment, the condensate in the water storage chamber drips downstream through the drip hole in the water storage chamber. 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 come into full contact. This fully utilizes the condensate for dehumidification and solves the problems of poor condensation effect caused by excessive condensate flow rate and small contact area between the condensate and the drying airflow.

[0077] Example 4

[0078] Unlike Example 1, the position and / or extension direction and / or extension length of the water-retaining rib 152 are adjustablely arranged within the necking section 135; the position and / or extension direction and / or extension length of the water-retaining rib 152 can be adjusted according to actual needs to improve the condensation effect and shorten the drying time.

[0079] In this embodiment, the position and / or extension direction and / or extension length of the water storage rib 152 can be adjusted to adapt to different condensation requirements, thus solving the problem that the fixed position and size of the water storage rib 152 cannot meet different drying requirements.
