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 in the inner drum to achieve the drying of the clothes. In the existing technology, the structural design of the condenser duct is unreasonable, resulting in insufficient contact between the drying airflow and the condensate water and a small heat exchange area, leading to low condensation efficiency, incomplete dehumidification, and long drying time.

[0014] The sidewall of the condensate outlet pipe section has multiple condensate outlets, which are arranged at intervals along the length of the condensate outlet pipe section.

[0015] Alternatively, the condensate outlet pipe section is provided with multiple baffles, and the multiple baffles are provided one-to-one with the multiple condensate outlets, thereby reducing the flow area of ​​the condensate outlet pipe section.

[0016] Alternatively, the baffle is slidably disposed within the condensate outlet pipe section, and the flow area of ​​the condensate outlet pipe section can be adjusted by adjusting the position of the baffle.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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 area is small, resulting in low condensation efficiency, incomplete dehumidification, and long drying time.

[0039] This invention creatively provides a garment processing device, including an outer drum and a drying system. A drying air inlet is formed at the opening of the outer drum, and a drying air outlet is formed on the drum wall. The drying system includes a condensing air duct, a heating air duct, and a heat exchange plate. The condensing air duct and the drying air outlet are connected, and a condensing air outlet is formed on the side wall of the condensing air duct. The heating air duct connects the drying air inlet and the condensing air outlet. The heat exchange plate is disposed within the condensing air duct, and multiple external guide ribs are provided on the heat exchange plate surface. These multiple external guide ribs are distributed along the extension direction of the condensing air duct on the plate surface and form baffle surfaces in different directions. Condensate can change direction as it flows along the heat exchange plate surface through the multiple external guide ribs.

[0040] As the condensate flows through the outer guide ribs, its flow direction is constantly changed, increasing the heat exchange area between the drying airflow and the condensate. This ensures full contact between the drying airflow and the condensate, improving condensation efficiency, ensuring thorough dehumidification, and shortening the drying time. This solves the problems of insufficient contact and small heat exchange area between the drying airflow and the condensate due to unreasonable structural design of the condenser duct in the existing technology, and also solves the problems of low condensation efficiency and incomplete dehumidification in the existing condenser duct.

[0041] Example 1

[0042] like Figures 1 to 7 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 has a peripheral wall 11 and a 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 rear wall 12, including a first drying air outlet 121 and a second drying air outlet 122; the first drying air outlet 121 is located above the second drying air outlet 122; the inner drum is rotatably disposed inside the outer drum 1 for carrying garments; filters are provided at the drying air inlet, the first drying air outlet 121, and the second drying air outlet 122. The system filters lint from the drying airflow. A flushing valve is installed at the drying air inlet, the first drying air outlet 121, and the second drying air outlet 122. The flushing valve 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. The horizontal reference plane 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.

[0043] The drying system includes:

[0044] A condensing air duct 133 has a first condensing air inlet at one end and a second condensing air inlet at the other end. A condensing air outlet 134 is formed on the side wall of the condensing air duct 133, and the condensing air outlet 134 is close to the first drying air outlet 121. 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 air duct 133 is located on the outer side of the rear wall 12 of the outer cylinder and is formed by a condensing shell 131 and a condensing cover 132 covering the condensing shell 131. The condensing shell 131 is located on the rear wall 12 of the outer cylinder. On the outer side surface; specifically, the condenser shell 131 is integrally injection molded with the outer cylinder rear wall 12 to reduce the thermal resistance of the outer cylinder rear wall 12 and the condenser air duct 133 during drying. The outer cylinder 1, heated by the drying airflow, can keep the drying airflow circulating in the condenser air duct 133 warm and raise its temperature, reduce heat loss, and achieve faster drying. The condenser shell 131 and the condenser cover 132 are fixed by welding, screws, or fixing clips. The condenser shell 131 and the condenser cover 132 are sealed together to prevent water leakage from the condenser air duct 133. An outer guide rib 213 is provided inside the condenser air duct 133. The outer guide rib 213 can be a straight structure or an arc structure.

[0045] The heating air duct 32 has one end connected to the drying air inlet and the other end connected to the condenser air outlet 134 via the drying fan 31. The inner side of the rear wall 12 of the outer cylinder serves as a condensation surface through which condensate flows. When a portion of the drying airflow inside the outer cylinder 1 flows from bottom to top along this condensation surface, it exchanges heat with the condensate flowing through the condensation surface and then enters the condenser air duct 133 through the first drying air outlet 121. A heating device is installed inside the heating air duct 32 to heat the drying airflow flowing through it. Specifically, the heating device is an electric heating element. The drying airflow inside the heating air duct 32 enters the opening of the inner cylinder through the drying air inlet.

[0046] A heat exchange plate 21 is disposed within a condensing air duct 133, and multiple external guide ribs 213 are provided on the heat exchange plate 21. These external guide ribs 213 are distributed along the extension direction of the condensing air duct 133 on the plate surface of the heat exchange plate 21, forming baffles in different directions. This allows condensate to flow back and forth along the plate surface of the heat exchange plate 21 through the multiple external guide ribs 213. Preferably, the multiple external guide ribs 213 are spaced apart on the plate surface of the heat exchange plate 21. The position and / or extension direction and / or extension length of the external guide ribs 213 are adjustable. When condensate flows along the plate surface of the heat exchange plate 21, it can flow through the multiple external guide ribs 213. Another part of the drying airflow inside cylinder 1 can enter the condensing air duct 133 through the second drying air outlet 122 and complete heat exchange with the condensate flowing through the outer guide rib 213; this expands the heat exchange area between the drying airflow and the condensate, allowing the drying airflow and the condensate to fully contact each other, improving the condensation effect and shortening the drying time; the drying airflow in the condensing air duct 133 can enter the heating air duct through the condensing air outlet 134; the outer cylinder 1, inner cylinder, condensing air duct 133, drying fan 31 and heating air duct 32 constitute the drying airflow circuit, and the drying fan 31 provides power to the drying airflow, so that the drying airflow circulates in the drying airflow circuit.

[0047] In response to the problem that the heat exchange efficiency of the heat exchange plate 21 is low due to the unreasonable setting position of the external guide rib 213, this embodiment proposes that the heat exchange plate 21 is provided with a plurality of first external guide rib groups and a plurality of second external guide rib groups. The first external guide rib group includes an external guide rib 213, and the plurality of first external guide rib groups are spaced apart on the plate surface of the heat exchange plate 21.

[0048] The second external guide rib group includes two external guide ribs 213. In the second external guide rib group, one end of one external guide rib 213 is connected to one end of the other external guide rib 213 and the two external guide ribs 213 intersect. Multiple second external guide rib groups are spaced apart on the plate surface of the heat exchange plate 21.

[0049] Multiple first external guide rib groups and multiple second external guide rib groups are spaced apart on the surface of the heat exchange plate 21; when the condensate flows along the surface of the heat exchange plate 21, it can flow through the external guide ribs 213 of the first and second external guide rib groups, so that the condensate can cover the entire surface of the heat exchange plate 21, expand the heat exchange area between the condensate and the drying airflow, and improve the heat exchange efficiency between the condensate and the drying airflow.

[0050] Furthermore, the heat exchange plate 21 also has through holes that connect the two oppositely arranged plate surfaces of the heat exchange plate 21. The condensate on one plate surface of the heat exchange plate 21 can enter the other plate surface of the heat exchange plate 21 through the through holes, extending the flow path of the condensate, changing the flow of the condensate, and allowing the condensate to fully contact the drying airflow and complete the heat exchange.

[0051] Based on this, at least one end of the through hole is a pointed tip; preferably, the through hole has a triangular structure; the through hole includes a first through hole 214 and a second through hole 215; the first through hole 214 is provided in a one-to-one correspondence with the first outer guide rib group and one hole wall of the first through hole 214 is provided parallel to the outer guide rib 213 of the first outer guide rib group; the condensate flowing along the outer guide rib 213 of the first outer guide rib group can flow along the plate surface where the outer guide rib 213 is located, and the condensate that does not flow along the outer guide rib 213 of the first outer guide rib group can enter the side of the plate surface opposite to the plate surface where the outer guide rib 213 is located through the first through hole 214;

[0052] The second through hole 215 is provided in a one-to-one correspondence with the second outer guide rib group, and the two holes of the second through hole 215 are respectively arranged parallel to the two outer guide ribs 213 of the second outer guide rib group; the condensate flowing along the outer guide ribs 213 of the second outer guide rib group can flow along the plate surface where the outer guide ribs 213 are located, and the condensate that does not flow along the outer guide ribs 213 of the second outer guide rib group can enter the side of the plate surface opposite to the plate surface where the outer guide ribs 213 are located through the second through hole 215.

[0053] To address the issue of the small heat exchange area of ​​the heat exchange plate 21, this embodiment proposes that the structure of the heat exchange plate 21 is adapted to the structure of the condensing air duct 133, and the heat exchange plate 21 can cover the entire condensing air duct 133; the heat exchange area of ​​the heat exchange plate 21 is close to the area of ​​the condensing cover 132; multiple external guide ribs 213 are provided on one plate surface of the heat exchange plate 21; or multiple external guide ribs 213 are provided on both plate surfaces of the heat exchange plate 21, thereby increasing the heat exchange area of ​​the heat exchange plate 21, extending the flow time of the condensate, and enabling the condensate to complete heat exchange with more drying airflow; and reducing the moisture content in the drying airflow.

[0054] In addition, the drying system also includes a condenser pipe 22, which is disposed on the heat exchange plate 21 and includes a condensate inlet pipe section 221 and a condensate outlet pipe section 222. The condensate outlet pipe section 222 is connected to the condensate inlet pipe section 221 and the extension direction of the condensate outlet pipe section 222 is consistent with the extension direction of the heat exchange plate 21. The condensate inlet pipe section 221 can supply condensate to the condensate outlet pipe section 222. Specifically, the condenser pipe 22 is disposed on the top of the heat exchange plate 21.

[0055] The sidewall of the condensate outlet pipe section 222 has multiple condensate outlets 223, which are arranged sequentially at intervals along the length of the condensate outlet pipe section 222; the condensate flowing out through the multiple condensate outlets 222 can flow along the surface of the heat exchange plate 21.

[0056] To address the issue of low condensate flow rate at the condensate outlet 222, which is far from the condensate inlet pipe section 221, this embodiment proposes that multiple baffles 23 be installed inside the condensate outlet pipe section 222. The multiple baffles 23 are installed in a one-to-one correspondence with the multiple condensate outlets 223, and the baffles 23 reduce the flow area of ​​the condensate outlet pipe section 222.

[0057] 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. The condensate from the outside can enter the outer cylinder 1 through the condenser inlet valve 141 and flow from top to bottom along the inner side of the rear wall 12 of the outer cylinder and exchange heat with the drying airflow flowing through the inner side of the rear wall 12 of the outer cylinder.

[0058] The side wall of the condenser shell 131 is provided with a condenser external water inlet valve 142, which is connected to the condenser water inlet pipe section 221. External condensate can enter the condenser water inlet pipe section 221 through the condenser external water inlet valve 142 and flow out through multiple condensate outlets 223. Then, it flows from top to bottom along the surface of the heat exchange plate 21 and exchanges heat with the drying airflow in the condenser air duct 133. The external 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.

[0059] 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 133 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 133 via the second drying air outlet 122; or both the first drying air outlet 121 and the second drying air outlet 122 can be opened, allowing a portion of the drying airflow inside the outer cylinder 1 to enter the condenser duct 133 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 133 via the second drying air outlet 122.

[0060] The condensing air duct 133 includes a first condensing section 1331 and a second condensing section 1332. One end of the first condensing section 1331 is connected to the first drying air outlet 121, and one end of the second condensing section 1332 is connected to the second drying air outlet 122. The other end of the first condensing section 1331 and the other end of the second condensing section 1332 are connected. Both the first condensing section 1331 and the second condensing section 1332 have an arc-shaped structure, and the flow area of ​​the first condensing section 1331 is smaller than the flow area of ​​the second condensing section 1332.

[0061] To address the problem of low drying efficiency caused by the unreasonable structural design of the first drying air outlet 121 and the second drying air outlet 122, this embodiment proposes that the diameter of the first drying air outlet 121 be d1 and the diameter of the second drying air outlet 122 be d2, satisfying: 18mm≤d1≤35mm, 35mm≤d2≤50mm. In this way, most of the drying airflow enters the condensing air duct 133 through the second drying air outlet 122, while a small portion of the drying airflow enters the condensing air duct 133 through the first drying air outlet 121, thereby increasing the heat exchange area between the drying airflow and the condensate and improving the condensation effect.

[0062] The extension length of the outer guide rib 213 is L, 20mm≤L≤100mm; it extends the flow path of the condensate and expands the heat exchange area between the condensate and the drying airflow; the outer guide ribs 213 are arranged at intervals and staggered, and when the drying airflow flows through the condensation duct 133, the outer guide ribs 213 can block the lint, and the lint can fall down with the condensate flowing along the outer guide ribs 213 and finally be discharged from the outer cylinder 1; it can prevent lint from entering the drying fan and ensure the reliable operation of the drying fan.

[0063] Multiple first drying air outlets 121 are sequentially arranged along the extension direction of the first condensing section 1331, 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 condensing section 1332, 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 condensing air duct 133 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.

[0064] In addition, multiple inner guide ribs 15 are provided at intervals on the inner side of the outer cylinder rear wall 12. The extension direction of each inner guide rib 15 is inclined relative to the vertical direction. In two adjacent inner guide ribs 15, the water outlet end of the upstream inner guide rib 15 is close to the water inlet end of the downstream inner guide rib 15, so that the condensate flowing along the inner side of the outer cylinder rear wall 12 can flow through multiple inner guide ribs 15. The position and / or extension direction and / or extension length of the inner guide ribs 15 can be adjusted.

[0065] When the condensate flows through the inner guide rib 15, the heat exchange time and heat exchange area between the condensate and the drying airflow are extended, thus improving the condensation effect.

[0066] The garment processing equipment operates in a drying process. When the temperature of the drying airflow inside the inner drum reaches the drying temperature, the condenser inner water inlet valve 141 opens, allowing a portion of the condensate to enter the outer drum 1 through the condenser inner water inlet valve 141 and flow along the inner side of the outer drum rear wall 12. This portion of the condensate exchanges heat with the drying airflow flowing along the inner side of the outer drum rear wall 12. This portion of the drying airflow enters the condenser duct 133 through the first drying air inlet 121. The condenser outer water inlet valve 142 opens, allowing another portion of the condensate to enter the condenser tube 21 through the condenser outer water inlet valve 142, and then flow out through the condenser outlet 223 and flow along the surface of the heat exchange plate 21. This portion of the condensate fully contacts and exchanges heat with the drying airflow in the condenser duct 133, improving condensation efficiency and shortening the drying time.

[0067] Multiple screw posts are provided on the side of the condenser cover 132 near the rear wall 12 of the outer cylinder, and the multiple screw posts are spaced apart along the length of the condenser cover 132; a positioning protrusion is formed on the heat exchange plate 21, which positions the heat exchange plate 21 on the condenser cover 132, and the heat exchange plate 21 is fixed on the condenser cover 132 by screws; a slot 216 is formed on the top of the heat exchange plate 21, and the condenser tube 22 is disposed in the slot 216.

[0068] In this embodiment, when the condensate flows along the surface of the heat exchange plate, it can flow through multiple external guide ribs and exchange heat with the drying airflow flowing through the condensation duct. This increases the heat exchange area between the drying airflow and the condensate, allowing them to fully contact each other and improving the condensation efficiency. This solves the problem in the prior art where the unreasonable structural design of the condensation duct leads to insufficient contact between the drying airflow and the condensate, and a small heat exchange area. The condensate on one side of the heat exchange plate 21 can enter the other side of the heat exchange plate 21 through through holes, extending the flow path of the condensate and changing its flow. This allows the condensate to fully contact the drying airflow, solving the problem of the unreasonable structural design of the heat exchange plate resulting in a single flow velocity and flow pattern of the condensate and poor condensation effect.

[0069] The condenser tube 22 is installed on the heat exchange plate 21 and includes a condensate outlet pipe section 222. Multiple baffles 23 are installed inside the condensate outlet pipe section 222. The multiple baffles 23 are installed one-to-one with the multiple condensate outlets 223. The baffles 23 reduce the flow area of ​​the condensate outlet pipe section 222, reduce the flow rate of the condensate, prolong the heat exchange time between the condensate and the drying airflow, and solve the problem that the condensate cannot fully contact the drying airflow due to the excessive flow rate of the condensate.

[0070] When the condensate flows through the outer guide rib 213 and the inner guide rib 15, the heat exchange time and heat exchange area between the condensate and the drying airflow are extended, thus improving the condensation effect.

[0071] Example 2

[0072] Based on the difference in Embodiment 1, each inner guide rib 15 is formed with a guide groove and a drip hole. The extension direction of the guide groove is consistent with the extension direction of the inner guide rib. The drip hole is close to the inner side of the rear wall 12 of the outer cylinder and multiple drip holes are provided. Multiple drip holes are arranged sequentially at intervals along the extension direction of the guide groove and each drip hole is connected to the guide groove.

[0073] In two adjacent inner guide ribs 15, the condensate in the upstream guide groove can be discharged through the corresponding drip hole and flow along the transition surface to the downstream guide groove.

[0074] The transition surface is the portion of the inner side of the outer cylinder rear wall 12 between two adjacent inner guide ribs 15.

[0075] In this embodiment, the condensate in the guide channel is diverted and discharged through each drip hole and flows along the 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 and make full use of the condensate for dehumidification. This solves the problems of excessive condensate flow rate and small contact area between the condensate and the drying airflow, which lead to poor condensation effect.

[0076] Example 3

[0077] Unlike Embodiment 1, the baffle 23 is slidably disposed within the condensate outlet pipe section 222. By adjusting the position of the baffle 23, the flow area of ​​the condensate outlet pipe section 222 can be adjusted, thereby achieving different condensation requirements.

[0078] In this embodiment, the position of the baffle 23 can be adjusted according to the actual condensation requirements to adjust the flow area of ​​the condensate outlet pipe section 222, expand the application range of the condensate outlet pipe section 222, and solve the problem that the fixed position of the baffle 23 leads to a narrow application range of the condensate outlet pipe section 222.

It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
