Description

Technical Field

[0001] This invention belongs to the field of garment processing technology, and particularly relates to an outer tube assembly and garment processing equipment. Background Technology

[0002] For clothing processing equipment using water-cooled drying, the drying system includes a second condensation zone and a heating duct. The hot and humid drying airflow enters the second condensation zone and comes into direct or indirect contact with the condensate water to complete heat exchange, thus transforming into a dry and cold drying airflow. Then, it enters the heating duct through a fan and 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 outer drum air outlet and the second condensation zone is unreasonable.

[0042] Example 1

[0043] <Outer tube assembly>

[0044] like Figures 1 to 3 As shown, this embodiment provides an outer cylinder assembly for a garment processing device; the outer cylinder assembly includes an inner cylinder, the inner cylinder including a rear wall; the outer cylinder assembly includes an outer cylinder 1 and a condenser cap 132;

[0045] The outer cylinder 1 includes an outer cylinder rear wall 12 and an outer cylinder peripheral wall 11. The outer cylinder rear wall 12 and the inner cylinder rear wall are correspondingly arranged, and a first condensation zone is formed between the inner side surface of the outer cylinder rear wall 12 and the outer side surface of the inner cylinder rear wall. The outer cylinder peripheral wall 11 surrounds one axial side of the outer cylinder rear wall 12, and a first water inlet is formed in the outer cylinder peripheral wall 11 or the outer cylinder rear wall 12. Condensate can enter through the first water inlet and flow through the first condensation zone.

[0046] A condenser shell 131 is formed on the outer side of the rear wall 12 of the outer cylinder, and a condenser cover 132 is provided on the condenser shell 131. A second condensation zone is formed between the outer side of the rear wall 12 of the outer cylinder, the condenser shell 131 and the condenser cover 132. A second water inlet is formed on the rear wall 12 of the outer cylinder, the condenser shell 131 or the condenser cover 132. Condensed water can enter through the second water inlet and flow through the second condensation zone.

[0047] The rear wall 12 of the outer cylinder has a first outer cylinder air outlet 121 and a second outer cylinder air outlet 122. The first outer cylinder air outlet 121 is located above the second outer cylinder air outlet 122. The first outer cylinder air outlet 121 connects to the upper ends of the first condensation zone and the second condensation zone, and the second outer cylinder air outlet 122 connects to the lower ends of the first condensation zone and the second condensation zone. A portion of the drying airflow inside the outer cylinder 1 can flow through the first condensation zone and enter the second condensation zone through the first outer cylinder air outlet 121. Another portion of the drying airflow inside the outer cylinder 1 can enter through the second outer cylinder air outlet 122 and flow through the second condensation zone.

[0048] Specifically, the condenser shell 131 is integrally injection molded with the rear wall 12 of the outer cylinder, which reduces the thermal resistance of the first and second condensation zones during drying. The outer cylinder 1, heated by the drying airflow, can maintain and raise the temperature of the drying airflow circulating in the first and second condensation zones, 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 in the second condensation zone.

[0049] To address the problem of low heat exchange efficiency between the drying airflow and condensate due to an unreasonable condensation structure design in the outer cylinder 1, this embodiment proposes that a first condensation surface be formed on the inner side of the rear wall 12 of the outer cylinder, and a first condensation zone be formed between the first condensation surface and the outer side of the rear wall of the inner cylinder; the first water inlet is designed such that condensate flows from top to bottom along the first condensation surface after entering the first condensation zone; the drying airflow flows from bottom to top along the first condensation surface, so that the condensate and the drying airflow can fully contact each other, thereby improving the heat exchange efficiency;

[0050] A second condensing surface is formed on the outer side of the rear wall 12 of the outer cylinder, and a second condensing zone is formed between the second condensing surface, the condensing shell 131 and the condensing cover 132; the second water inlet is designed so that the condensed water flows from top to bottom along the second condensing surface after entering the second condensing zone; the drying airflow flows from bottom to top along the second condensing surface, so that the condensed water and the drying airflow are in full contact, thereby improving the heat exchange efficiency.

[0051] Furthermore, a first water inlet is formed at one end of the outer cylinder peripheral wall 11 near the bottom wall 12 of the outer cylinder, and a first water inlet valve 141 is provided at the first water inlet, which is connected to the first condensation zone; a first water inlet is formed on the side wall of the condensation shell, and a second water inlet valve 142 is provided at the second water inlet, which is connected to the second condensation zone.

[0052] A portion of the condensate can enter the first condensation zone through the first inlet valve 141 and flow from top to bottom along the first condensation surface, where it can exchange heat with the drying airflow flowing from bottom to top across the first condensation surface; another portion of the condensate can enter the second condensation zone 133 through the second inlet valve 142 and flow from top to bottom along the second condensation surface, where it can exchange heat with the drying airflow flowing from bottom to top across the second condensation surface.

[0053] 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 actual drying needs, the first outer cylinder air outlet 121 can be opened and the second outer cylinder air outlet 122 closed, allowing the drying airflow inside the outer cylinder 1 to enter the second condensation zone 133 via the first condensing surface 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 closed, allowing the drying airflow inside the outer cylinder 1 to enter the second condensation zone 133 via the second outer cylinder air outlet 122; or both the first and second outer cylinder air outlets 122 can be opened, allowing a portion of the drying airflow inside the outer cylinder 1 to enter the second condensation zone 133 via the first condensing surface and the first outer cylinder air outlet 121, while another portion of the drying airflow inside the outer cylinder 1 enters the second condensation zone 133 via the second outer cylinder air outlet 122.

[0054] To address the problem of low heat exchange efficiency between condensate and drying airflow caused by unreasonable position and structural design of the first outer cylinder air outlet 121 and the second outer cylinder air outlet 122, this embodiment proposes that the first outer cylinder air outlet 121 is located on the upper side of the horizontal reference plane, and the second outer cylinder air outlet 122 is located on the lower side of the horizontal reference plane; the flow area of ​​the first outer cylinder air outlet 121 is smaller than the flow area of ​​the second outer cylinder air outlet 122.

[0055] The horizontal reference plane is the plane that passes through the axis of the outer cylinder and is parallel to the horizontal plane.

[0056] Furthermore, the condenser shell 131 is formed with a condenser air outlet 134, which is located between the first outer cylinder air outlet 121 and the second outer cylinder air outlet 122 and is close to the first outer cylinder air outlet 121.

[0057] To address the problem of low drying efficiency caused by the unreasonable structural design of the first outer drum air outlet 121 and the second outer drum air outlet 122, this embodiment proposes to optimize the structure of the first outer drum air outlet 121 and the second outer drum air outlet 122. The diameter of the first outer drum air outlet 121 is designed to be d1, and the diameter of the second outer drum air outlet 122 is designed to be d2, satisfying: 5mm≤d1≤50mm, 8mm≤d2≤80mm. In this way, most of the drying airflow enters the second condensation zone 133 through the second outer drum air outlet 122, while a small portion of the drying airflow enters the second condensation zone 133 through the first outer drum air outlet 121. This increases the heat exchange area between the drying airflow and the condensate, improving the condensation effect. It also avoids excessive airflow from the second outer drum air outlet, which could draw condensate from the outer drum into the second condensation zone, and avoids excessive airflow from the first outer drum air outlet, which could cause too much drying airflow to enter the second condensation zone 133 without sufficient contact with the clothes in the inner drum.

[0058] To address the issue of low drying efficiency caused by the unreasonable positioning of the first outer cylinder air outlet 121 and the second outer cylinder air outlet 122, this embodiment proposes that the angle between the plane containing the axis of the first outer cylinder air outlet 121 and the vertical reference plane be α, satisfying: -60°≤α≤60°; and the angle between the plane containing the axis of the second outer cylinder air outlet 122 and the vertical reference plane be β, satisfying: -80°≤β≤80°.

[0059] The plane containing the axis of the first outer cylinder air outlet 121 is the plane passing through the axis of the first outer cylinder air outlet 121 and the axis of the outer cylinder 1; the plane containing the axis of the second outer cylinder air outlet 122 is the plane passing through the axis of the second outer cylinder air outlet 122 and the axis of the outer cylinder 1; the vertical reference plane is the plane passing through the axis of the outer cylinder 1 and parallel to the vertical plane.

[0060] The second condensation zone is equipped with an external guide rib 15, which can be a straight or arc-shaped structure. The external guide rib 15 can guide the flow 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.

[0061] Furthermore, multiple outer guide ribs 15 are provided, and the multiple outer guide ribs 15 are arranged sequentially at intervals along the vertical direction, and two adjacent outer guide ribs 15 are staggered in the horizontal direction; the extension direction of each outer guide rib 15 is inclined relative to the vertical direction, and two adjacent outer guide ribs 15 have different extension directions; the position and / or extension direction and / or extension length of the outer guide ribs 15 can be adjusted.

[0062] To address the issue of poor flow guidance effect caused by the unreasonable placement of the outer guide ribs 15, this embodiment proposes that the outer guide ribs 15 include multiple first outer guide ribs, all of which are disposed on the condenser cover 132 and are sequentially spaced along the extension direction of the condenser cover 132; the extension direction of each first outer guide rib is inclined relative to the vertical direction, and two adjacent first outer guide ribs have different extension directions; after entering the second condensation zone 133, the condensed water flows along the inner side of the condenser cover 132 and passes through the multiple first outer guide ribs; on the one hand, the condensed water can exchange heat with the condenser cover 132; on the other hand, the condensed water can exchange heat with the drying airflow, both of which are beneficial to reducing the humidity of the drying airflow.

[0063] Furthermore, the position and / or extension direction and / or extension length of the first outer guide rib can be adjusted on the condenser cover 132; the position, extension direction and extension length of the first outer guide rib 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.

[0064] In two adjacent first outer guide ribs, the water outlet of the upstream first outer guide rib is close to the water inlet of the downstream first outer guide rib, so that the condensate entering the second condensation zone 133 can flow through multiple first outer guide ribs in sequence; the flow path of the condensate in the second condensation zone 133 is extended, the heat exchange area between the condensate and the drying airflow is increased, and the condensation efficiency is improved.

[0065] To address the problem of poor flow guidance effect caused by unreasonable structural design of the first outer guide rib, this embodiment proposes that the thickness of the first outer guide rib be h1, the width of the first outer guide rib be b1, and the length of the first outer guide rib be a1, satisfying: 1.5mm≤h1≤8mm, 1.5mm≤b1≤6mm, and 5mm≤a1≤80mm; so that the first outer guide rib can effectively guide the condensate water without affecting the flow of the drying airflow.

[0066] To address the issue of poor flow guidance effect caused by unreasonable placement of the outer guide ribs, this embodiment further proposes that the outer guide ribs also include multiple second outer guide ribs. These multiple second outer guide ribs are all disposed on the second condensation surface and are sequentially spaced along the extension direction of the condensation shell 131. The extension direction of each second outer guide rib is inclined relative to the vertical direction, and adjacent second outer guide ribs have different extension directions. After entering the second condensation zone 133, the condensed water flows along the second condensation surface and passes through the multiple second outer guide ribs. On the one hand, the condensed water can exchange heat with the rear wall 12 of the outer cylinder; on the other hand, the condensed water can exchange heat with the drying airflow. Both types of heat exchange are beneficial for reducing the humidity of the drying airflow.

[0067] Furthermore, the position and / or extension direction and / or extension length of the second outer guide rib can be adjusted on the second condensing surface; the position, extension direction and extension length of the second outer guide rib can be adjusted according to actual needs, thereby adjusting the flow rate and flow pattern of the condensate and improving the heat exchange efficiency between the condensate and the drying airflow.

[0068] In two adjacent second outer guide ribs, the water outlet of the upstream second outer guide rib is close to the water inlet of the downstream second outer guide rib, so that the condensate entering the second condensation zone 133 can flow through multiple second outer guide ribs in sequence; the flow path of the condensate in the second condensation zone 133 is extended, the heat exchange area between the condensate and the drying airflow is increased, and the condensation efficiency is improved.

[0069] To address the problem of poor flow guiding effect caused by unreasonable design of the second outer guide rib, this embodiment proposes that the thickness of the second outer guide rib be h2, the width of the second outer guide rib be b2, and the length of the second outer guide rib be a2, satisfying: 1.5mm≤h2≤12mm, 1.5mm≤b2≤10mm, and 5mm≤a2≤100mm.

[0070] To address the problem of poor condensation effect caused by unreasonable structural design of the second condensation zone 133, this embodiment proposes that the second condensation zone 133 includes a condensation zone A 1331 and a second condensation zone B 1332. One end of condensation zone A 1331 is connected to the air outlet 121 of the first outer cylinder, and one end of condensation zone B 1332 is connected to the air outlet 122 of the second outer cylinder. The other ends of condensation zone A 1331 and condensation zone B 1332 are connected. A condensation air outlet is formed on the side wall of condensation zone B 1332. Both condensation zone A 1331 and condensation zone B 1332 have an arc-shaped structure, and the flow area of ​​condensation zone A 1331 is smaller than the flow area of ​​condensation zone B 1332.

[0071] Multiple first outer cylinder air outlets 121 are sequentially arranged along the extension direction of condensation section A 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 condensation section B 1332, and each second outer cylinder air outlet 122 can be independently controlled to open or close; according to actual drying needs, the corresponding number and position 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 second condensation zone 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.

[0072] In addition, the first condensation surface is provided with multiple inner guide ribs, which are spaced apart on the first condensation surface, 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.

[0073] 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.

[0074] like Figure 1 , Figure 2 and Figure 4 As shown, in order to address the problem of low heat exchange efficiency between the drying airflow and the condensate in the second condensation zone, this embodiment proposes that a microchannel heat exchanger 2 be installed in the second condensation zone 133, and the microchannel heat exchanger 2 be located near the condensation outlet 134; the condensate can flow through the microchannel heat exchanger 2 and exchange heat with the drying airflow flowing through the second condensation zone 133, thereby improving the heat exchange efficiency between the drying airflow and the condensate.

[0075] The equivalent diameter of the channel in the microchannel heat exchanger 2 is d3, which satisfies the following condition: 10μm≤d3≤1000μm.

[0076] Furthermore, the microchannel heat exchanger 2 includes a support 21 and a condenser tube 22. The support 21 is arbitrarily positioned on the condenser shell 131 or the condenser cover 132, and the condenser tube 22 is positioned on the support 21. Along the cross-sectional direction of the second condensation zone 133, the condenser tube 22 has a serpentine structure.

[0077] One end of the condenser tube 22 is connected to the first water inlet, and the other end of the condenser tube 22 is connected to the second condensation zone 133; the condensate enters the condenser tube 22 through the first water inlet and exchanges heat with the drying airflow flowing through the microchannel heat exchanger 2, so that the drying airflow can be condensed quickly;

[0078] Specifically, the microchannel heat exchanger 2 is installed in the B condensation section 1332, and the microchannel heat exchanger 2 is close to the condensation outlet 134; the bracket 21 is fixed to the condensation shell 131 or condensation cover 132 by screws, clips or glue; the condensation tube 22 is a flat tube, and dozens of micro channels are formed inside the flat tube; the two ends of the flat tube are connected to the circular manifold, and the circular manifold is equipped with a baffle, which divides the microchannel heat exchanger into several processes;

[0079] During the drying process of the garment processing equipment, the condenser tube 22 of the microchannel heat exchanger 2 is constantly filled with flowing condensate to ensure that the surface of the condenser tube 22 is at a low temperature. When the drying airflow comes into contact with the surface of the condenser tube 22, the drying airflow is cooled down and condensate is released. The condensate flowing through the condenser tube 22 will flow out from the other end into the second condensation zone 133. The condensate flows along the outer guide rib 15 and can be evenly distributed in the second condensation zone 133. It then comes into contact with the drying airflow in the second condensation zone 133 again, which cools down the drying airflow and releases moisture, thus achieving the drying purpose.

[0080] <Clothing Processing Equipment>

[0081] like Figures 1 to 3 As shown, this embodiment provides a garment processing device, including an inner drum, a heating air duct, and an outer drum assembly as described in any of the above. The inner drum is rotatably disposed inside the outer drum 1 for carrying garments. The inner drum includes an inner drum rear wall, which is correspondingly disposed with the outer drum rear wall. A drying air inlet is formed at the opening of the outer drum 1. Filters are provided at the drying air inlet, the first outer drum air outlet 121, and the second outer drum air outlet 122 to filter lint in the drying airflow. A rinsing valve is provided at the drying air inlet, the first outer drum air outlet 121, and the second outer drum air outlet 122. The rinsing valve can spray water onto the corresponding filter to clean the corresponding filter. Specifically, a door seal is provided at the opening of the outer drum 1, and the door seal forms a drying air inlet.

[0082] One end of the heating air duct is connected to the drying air inlet, and the other end of the heating air duct is connected to the condenser air outlet 134 via the drying fan; the drying airflow in the second condensation zone 133 can enter the heating air duct through the condenser air outlet 134, and the drying airflow in the heating air duct enters the cylinder opening of the inner cylinder through the drying air inlet; a heating device is installed in the heating air duct to heat the drying airflow flowing through the heating air duct; the outer cylinder 1, the inner cylinder, the first condensation zone, the second condensation zone 133, the drying fan, and the heating air duct constitute a drying airflow loop, and the drying fan provides power to the drying airflow, causing the drying airflow to circulate in the drying airflow loop; specifically, the heating device is an electric heating element;

[0083] <Drying Control Methods>

[0084] This embodiment provides a drying control method for a garment processing device. The garment processing device is any of the garment processing devices described above. The garment processing device is equipped with a drying process, which includes a drying stage and a drying and cooling stage. When the garment processing device is in the drying stage, the drying control method includes:

[0085] S1. Obtain the current temperature of the drying airflow inside the outer cylinder 1;

[0086] S2. Determine whether the current temperature is within the preset temperature range;

[0087] S3. Based on the judgment result of whether the current temperature is within the preset temperature range, control the condensate to enter the first condensation zone and / or the second condensation zone 133;

[0088] Specifically, when the garment processing equipment is running the drying process, both the heating equipment and the drying fan are turned on; the preset temperature range is 55℃-65℃.

[0089] Furthermore, S3 includes:

[0090] When the current temperature is within the preset temperature range, the first water inlet valve 141 is opened, allowing a portion of the condensate to enter the first condensation zone through the first water inlet valve 141 and flow along the first condensation surface while timing is recorded; at this time, the condensate flowing through the first condensation surface exchanges heat with the drying airflow, thus performing preliminary dehumidification on the drying airflow.

[0091] Compare the timed duration with the preset duration;

[0092] If the timed duration exceeds the preset duration, the second water inlet valve 142 is opened, allowing another portion of the condensate to enter the second condensation zone 133 through the second water inlet valve 142 and flow along the outer guide ribs. At this time, the first condensation surface, the second condensation surface, and the condensation cover 132 can all be irrigated with condensate, allowing the condensate to fully contact the drying airflow, causing the drying airflow to cool down rapidly and precipitate a large amount of condensate. This ensures that the moisture evaporation from the clothes inside the inner drum is sufficient, and that the moisture condensation in the drying airflow is also sufficient, allowing the clothes inside the inner drum to dry quickly. The preset duration is 10 minutes.

[0093] When the garment processing equipment is in the drying and cooling stage, the first water inlet valve 141 and the second water inlet valve 142 are opened to lower the temperature inside the inner drum and prevent excessively high temperatures from damaging the garments.

[0094] Example 2

[0095] 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.

[0096] 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;

[0097] The first transition surface is the portion of the inner side of the condenser cap 132 between two adjacent first outer guide ribs.

[0098] 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.

[0099] 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;

[0100] 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.

[0101] 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.

[0102] Example 3

[0103] Unlike Embodiment 1, the condenser shell 131 includes a condenser outer shell and a condenser inner shell. The condenser outer shell is sleeved on the outside of the condenser inner shell, and the condenser inner shell, the second condensation surface, and the condenser cover 132 form a second condensation zone 133. A flow guiding rib is formed on the inner side of the condenser inner shell.

[0104] A condensate drain is formed between the outer shell and the inner shell of the condenser, through which condensate can flow.
