A condenser and clothing treatment device

[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to Chinese Patent Application No. 202411734847.2, filed on November 28, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of garment washing and care technology, and in particular to a condenser and garment processing equipment. Background Technology

[0004] Taking a washer-dryer combo as an example, its drying process generally requires the use of a condenser to dehumidify the hot and humid airflow. The working principle of the condenser is as follows: condensate is sprayed into the condensation channel of the condenser and exchanges heat with the hot and humid airflow in the condensation channel. The hot and humid air cools down to below the dew point, causing the hot and humid air to precipitate moisture, which is discharged from the condenser along with the condensate. The condensed hot and humid airflow becomes relatively dry and cold air.

[0005] Dry, cold air flowing out of the condenser enters the heating channel and is heated by the heater within the channel to form dry, hot air, which is then used to dry clothes. The space inside the condenser and the space inside the heating channel constitute the drying tunnel of the clothing processing equipment. In related technologies, the drying tunnel is prone to blockage, affecting the airflow within the tunnel, and the condenser's condensation efficiency is also low, both of which negatively impact the drying efficiency of the clothes. Summary of the Invention

[0006] In view of this, the present application aims to provide a condenser and a garment processing device, which is intended to reduce the probability of blockage in the drying duct of the garment processing device, and at the same time improve the condensation effect of the condenser, so as to improve the drying efficiency of the garment.

[0025] In some embodiments, the condensation channel includes a first sub-channel and an air inlet channel arranged at an angle, the first sub-channel communicating with the outside through the air inlet channel, the air inlet channel having the air inlet, and the first sub-channel being located downstream of the air inlet channel;

[0026] In a plane perpendicular to the axial direction of the air inlet channel, the cross-sectional area of ​​the air inlet channel is smaller than the cross-sectional area of ​​the first sub-channel; the liquid outlet section extends along the axial direction of the air inlet channel.

[0027] In some embodiments, the molded wall is located within the air inlet channel.

[0028] In some embodiments, the housing assembly includes a body and a partition wall, the body having the first sub-channel and the air inlet channel, and the partition wall being disposed at one end of the air inlet channel near the first sub-channel;

[0030] In some embodiments, the water mist surface is arranged to intersect the axial direction of the air inlet channel.

[0032] In some embodiments, the condensation channel further includes a second sub-channel, which is directly connected to the first sub-channel, and the extension direction of the second sub-channel intersects the extension direction of the first sub-channel.

[0033] In some embodiments, the projection of the spray area is located within the air inlet channel, projected onto a plane perpendicular to the axial direction of the air inlet channel.

[0043] In this embodiment of the condenser, the spray assembly can spray condensate in the form of a water mist and apply it to the condensation channel. As the hot, humid airflow passes through this channel cross-section, lint in the airflow is slowed down, wetted, and weighted, preventing it from moving forward with the airflow. This reduces the possibility of lint remaining in the drying tunnel, ensuring sufficient airflow and improving the drying efficiency of the garment processing equipment. Simultaneously, since the water mist surface also acts as a filter, there is no need to install filters or other filter elements in the drying tunnel to filter lint, nor are there any components needed to clean the filters. Thus, the garment processing equipment has relatively fewer components, which helps improve both production cost and efficiency.

[0044] In addition, the surface area of ​​the water mist surface is relatively large, that is, the heat exchange area with the humid airflow is also relatively large, which can improve the heat exchange efficiency between the condensate and the humid airflow, thereby improving the drying efficiency of the clothing processing equipment.

[0063] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0064] This application provides a garment processing device. Please refer to Figure 1. The garment processing device includes a cylindrical assembly 2 and a condenser 1 according to any embodiment of this application.

[0065] Clothing processing equipment may include, for example, dryers, washer-dryer combos, etc., and this application does not limit it.

[0066] The drum assembly 2 has a garment processing chamber inside, where garments undergo washing, dehydration, or drying processes.

[0067] The condenser 1 is disposed on the cylinder assembly 2. Exemplarily, the cylinder assembly 2 may include an inner cylinder and an outer cylinder, the inner cylinder having a clothing handling chamber and being rotatably supported inside the outer cylinder, and the condenser 1 being disposed on the outer cylinder.

[0068] Condenser 1 is used to dehumidify the hot and humid airflow generated in the clothing processing chamber. Its specific working principle is as follows: condenser 1 is filled with condensate, and the hot and humid airflow in the clothing processing chamber enters condenser 1 and exchanges heat with the condensate in condenser 1. The hot and humid air cools down to below the dew point, causing the hot and humid air to precipitate moisture, which is discharged from condenser 1 along with the condensate. The condensed hot and humid airflow becomes relatively dry and cold air.

[0069] There is no limitation on the specific type of condensate. For example, the condensate can be water.

[0070] Downstream of the condenser 1 is a heating channel 3. The space of the heating channel 3 and the internal space of the condenser 1 together constitute the drying tunnel of the garment processing equipment. The heating channel 3 is equipped with a fan and a heater. The dry cold air flowing out of the condenser 1 flows through the heater, which heats the dry cold air and turns it into dry hot air. The dry hot air returns to the garment processing chamber to dry the clothes. In this way, the airflow circulates between the garment processing chamber and the drying tunnel to achieve continuous drying of the clothes. The fan provides power for the airflow circulation.

[0071] It's understandable that airflow may carry lint from clothing into the drying duct during its circulation. If no filter is installed in the duct, the lint will adhere and clog it, and over time, bacteria will grow. Even if a filter is installed to remove lint from the airflow, it's difficult to remove and clean it because it's inside the duct. Even if it is cleaned inside the duct, the cleaning solution may not evenly cover the filter, so some lint may remain on the filter and eventually clog the duct, reducing airflow and affecting drying efficiency.

[0072] In view of this, the present application also provides a condenser, as shown in Figure 2 or Figure 6. The condenser 1 includes a housing assembly 10 and a spray assembly 20.

[0073] The housing assembly 10 is provided with a condensation channel 10a, which has an air outlet 10b and an air inlet 10e. Specifically, the condensation channel 10a is connected to the interior of the heating channel 3 through the air outlet 10b and to the clothing processing chamber through the air inlet 10e. That is, the airflow flowing out of the air outlet 10b will enter the heating channel 3.

[0074] The inner wall of the condensation channel 10a, which is opposite to the air inlet 10e, is a windbreak wall 10d. After the airflow in the clothing processing chamber enters the condensation channel 10a through the air inlet 10e, the flow direction is changed under the action of the windbreak wall 10d.

[0075] The condensation channel 10a is where the hot and humid airflow and the condensate exchange heat. The condensation channel 10a is connected to the clothing processing chamber, and the hot and humid airflow in the clothing processing chamber enters the condensation channel 10a and is dehumidified within the condensation channel 10a.

[0076] The spray assembly 20 is used to guide the condensate into the condensation channel 10a. During use, the garment processing equipment supplies condensate to the condenser 1 through a liquid supply line. Specifically, the liquid supply line is connected to the spray assembly 20, and the condensate flows out of the liquid supply line, passes through the spray assembly 20, and enters the condensation channel 10a.

[0077] The spray assembly 20 is equipped with a water outlet unit located inside the condensation channel 10a. The condensate can be sprayed out through the water outlet unit to form a water mist surface that crosses the condensation channel 10a.

[0078] It should be noted that the condensate is sprayed out from the water outlet unit and appears as a large number of tiny particles. These tiny particles form a certain volume shape, and the surface of this volume shape is called the water mist surface.

[0079] When a humid, hot airflow carrying lint passes over a water mist surface, the humid, hot airflow exchanges heat with the condensate that forms the water mist surface. In related technologies, the condensate flows in a single or multiple columnar shape within the condenser, resulting in a relatively small heat exchange area between the condensate and the humid, hot airflow, leading to low heat exchange efficiency and affecting the drying efficiency of the clothes. However, the spray assembly 20 of this application can spray the condensate out and present it as a water mist surface. The surface area of ​​the water mist surface is relatively large, meaning that the heat exchange area with the humid, hot airflow is also relatively large, thereby improving the heat exchange efficiency between the condensate and the humid, hot airflow, and thus improving the drying efficiency of the clothes processing equipment.

[0080] Furthermore, the lint in the humid airflow is slowed down, moistened, and weighted, preventing it from moving forward with the airflow. In other words, the water mist surface also filters the circulating airflow within the garment processing equipment, thereby reducing the possibility of lint remaining in the drying tunnel, ensuring sufficient airflow within the tunnel, and ultimately improving the drying efficiency of the garment processing equipment.

[0081] Understandably, since the water mist surface also functions as a filter, there's no need for filters like screens to remove lint inside the drying tunnel, nor are there any parts for cleaning these filters. This results in fewer components in the garment processing equipment, which helps improve both production costs and efficiency.

[0082] The water outlet unit and the windbreak wall 10d are spaced apart. In this way, the water mist surface sprayed by the water outlet unit and the windbreak wall 10d can also be spaced apart, which facilitates the airflow to pass through the water mist surface.

[0083] It should be noted that there are no restrictions on the specific method of setting the interval. For example, the spray assembly 20 can be connected to the windbreak wall 10d, but there is a certain interval between the water outlet unit of the spray assembly 20 and the windbreak wall 10d; or, the spray assembly 20 can be not directly connected to the windbreak wall 10d, in which case there is also a certain interval between the water outlet unit and the windbreak wall 10d.

[0084] It should be noted that the specific direction of the spacing is not limited. For example, the water outlet unit and the windbreak wall 10d are spaced apart in a direction perpendicular to the windbreak wall 10d.

[0085] The specific location of the water outlet unit within the condensation channel 10a is not limited. For example, in the height direction of the condenser 1, the water outlet unit is lower than the air outlet 10b.

[0086] It should be noted that when condenser 1 is used in the garment processing equipment, the height direction of condenser 1 is the same as the height direction of the garment processing equipment. Please refer to the illustrations in Figures 2, 3, 6, or 7 for details.

[0087] The water outlet unit is lower than the air outlet 10b, which facilitates the formation of water mist in the area below the air outlet 10b. After the condensate is sprayed out by the water outlet unit, it falls under the action of gravity, making it difficult for it to flow out of the condenser 1 through the air outlet 10b and into the heating channel 3. As a result, more of the heat generated by the heater can be used to heat the airflow, which is beneficial to increase the temperature of the airflow. The higher temperature airflow has a better drying effect on clothes.

[0088] In summary, the condenser of this embodiment, with its spray assembly 20, can spray condensate in the form of a water mist and apply it to the condensation channel 10a. As the hot, humid airflow passes through this channel cross-section, lint in the airflow is slowed down, wetted, and becomes heavier, preventing it from moving forward with the airflow. This reduces the possibility of lint remaining in the drying tunnel, ensuring sufficient airflow and improving the drying efficiency of the garment processing equipment. Furthermore, since the water mist also acts as a filter, there is no need to install filters or other filters in the drying tunnel to remove lint, nor are there any components needed to clean the filters. Thus, the garment processing equipment has relatively fewer components, which helps improve both production cost and efficiency.

[0089] In addition, the surface area of ​​the water mist surface is relatively large, that is, the heat exchange area with the humid airflow is also relatively large, which can improve the heat exchange efficiency between the condensate and the humid airflow, thereby improving the drying efficiency of the clothing processing equipment.

[0090] In some embodiments, the surface where the water mist surface is located is used as an extension surface, and the cross-section formed by the extension surface and the condensation channel 10a is used as the flow channel cross-section. The area ratio of the water mist surface on the flow channel cross-section is not less than 80%. For example, it is 80%, 82%, 84%, 86%, 88%, 90%, 92%, 94%, 96%, 98%, 100%, etc.

[0091] The extended surface and the water mist surface are on the same plane. The extended surface can be understood as a surface formed by infinitely enlarging the water mist surface.

[0092] It is understandable that the larger the area of ​​the water mist surface on the flow channel cross section, the better the coverage effect of the water mist surface on the flow channel cross section. When the proportion reaches 100%, the airflow will pass through the water mist surface as a whole when it flows through the flow channel cross section. In this way, the gas as a whole can be effectively dehumidified and effectively filtered.

[0093] In this embodiment, the area ratio of the water mist surface on the flow channel cross-section is controlled to be no less than 80%. For the airflow passing through the flow channel cross-section, the water mist surface with this area ratio can achieve good dehumidification and filtration effects. It should be noted that the specific structure of the water outlet unit is not limited.

[0094] In some embodiments, the water outlet unit includes multiple liquid outlets 21b, each of which sprays out along its axial direction and forms a linear fluid in the radial direction of the condensation channel 10a, and the linear fluids together constitute a water mist surface.

[0095] "Linear fluid" refers to the condensate ejected from outlet 21b in a straight line.

[0096] The linear fluids can be arranged in parallel, or at least some of the linear fluids can be arranged at an angle.

[0097] Multiple linear fluids together form a water mist surface. For example, when at least some of the linear fluids are arranged at an angle, these linear fluids can be distributed crosswise to form a grid-like water mist surface. Taking one of the outlets 21b as an example, the extension direction of the linear fluid ejected from the outlet 21b is parallel to the axial direction of the outlet 21b.

[0098] It should be noted that there are no restrictions on the specific arrangement of each liquid outlet 21b.

[0099] For example, with a point as the center, each liquid outlet 21b is distributed counterclockwise or clockwise around the center, and at least some of the liquid outlets 21b have their axial direction passing through the center.

[0100] For example, all the liquid outlets 21b include a first part and a second part. The first part of the liquid outlets 21b is spaced apart along a first direction, and the second part of the liquid outlets 21b is spaced apart along a second direction. The first direction and the second direction intersect. The first part of the liquid outlets 21b sprays linear fluid in the second direction, and the second part of the liquid outlets 21b sprays linear fluid in the first direction. In this way, a water mist surface can also be formed.

[0101] In other embodiments, please refer to Figures 4 and 5, or Figures 8 and 9. The water outlet unit includes an outlet 21b and a spray area 20a communicating with the outlet 21b. The inner wall of the spray area 20a includes a forming wall 22a. The forming wall 22a and the outlet 21b are spaced apart along the axial direction of the outlet 21b. The condensate can be sprayed out through the outlet 21b and enter the spray area 20a, and leave the spray area 20a through the periphery of the forming wall 22a to form a water mist surface.

[0102] Here, the condensate is linearly sprayed out along the axial direction of the outlet 21b. At this time, the condensate has a certain flow velocity and the linear condensate impacts the inner wall of the spray area 20a. A portion of the condensate flows through the forming wall 22a and is sprayed out from the spray area 20a through the outer edge of the forming wall 22a. In this way, it can present the shape of a water mist surface.

[0103] It is understood that in this embodiment, the water mist surface extends approximately along the outer edge of the forming wall 22a. By setting the spray area 20a, the spray assembly 20 can form a water mist surface with only one outlet 21b, thus simplifying the structure of the spray assembly 20. Simultaneously, it also allows the spray assembly 20 to occupy less space within the condensation channel 10a, thereby reducing wind resistance within the condensation channel 10a, ensuring airflow, and guaranteeing the drying efficiency of the clothes.

[0104] Understandably, in order to ensure that the condensate sprayed through the spraying area 20a presents as a water mist, it is necessary to ensure that the condensate sprayed through the outlet 21b has a certain flow rate.

[0105] Understandably, with a constant flow rate of condensate in the supply pipeline, a smaller diameter at the outlet 21b results in a higher velocity of the condensate sprayed through it, making it easier for the condensate sprayed through the spray area 20a to form a water mist. However, the diameter of the outlet 21b cannot be too small. If it is too small, impurities such as scale in the condensate may cause blockage, affecting the reliability of the spray assembly 20. Therefore, the diameter of the outlet 21b needs to be controlled within a relatively reasonable range to ensure the reliable operation of the spray assembly 20 while maintaining the water mist appearance of the condensate sprayed through the spray area 20a.

[0106] The radius of the outlet 21b is R, the flow rate of the condensate is Q, and the velocity of the condensate ejected through the outlet 21b is v, where Q = πR. 2 ×v. Generally, Q is controlled at around 0.27 L / min, and the flow velocity v of the condensate sprayed through outlet 21b needs to be controlled at around 11 m / s. Substituting into the formula and rounding, the radius R of outlet 21b needs to be controlled at around 0.7 mm. That is, the diameter of outlet 21b should be less than 1.4 mm to allow the condensate to be sprayed out in the form of a water mist.

[0107] In some embodiments, referring to Figure 5 or Figure 9, the diameter of the outlet 21b ranges from 0.5 mm to 2 mm. For example, it is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, etc.

[0108] It should be noted that the diameter of the outlet 21b is as shown by D1 in Figure 5 or Figure 9.

[0109] Here, the diameter of the outlet 21b will not exceed 2mm, so that the condensate sprayed from the spray area 20a will be in the form of a water mist. At the same time, the diameter of the outlet 21b will not be less than 0.5mm, so that the scale in the condensate can flow through the outlet 21b, which helps to reduce the possibility of blockage at the outlet 21b, thereby improving the effectiveness of the spray assembly 20.

[0110] In some embodiments, referring to Figure 5 or Figure 9, the diameter of the outlet 21b ranges from 0.6 mm to 0.8 mm. For example, it is 0.6 mm, 0.62 mm, 0.64 mm, 0.66 mm, 0.68 mm, 0.7 mm, 0.72 mm, 0.74 mm, 0.76 mm, 0.78 mm, 0.8 mm, etc.

[0111] The diameter of the outlet 21b is within this range and is more suitable for a condensate flow rate of 0.25 L / min. Of course, if the condensate flow rate is increased to a level greater than 0.25 L / min, the diameter of the outlet 21b can be increased to a maximum of 2 mm.

[0112] When the flow rate of the condensate is low, the water mist particles forming the water mist surface are large, and the gaps between the particles are large, so small hairs can still pass through, resulting in poor filtration. When the flow rate of the condensate is high, the water mist particles forming the water mist surface are small, and the gaps between the particles are small, which makes it easier to intercept small hairs, but the amount of condensate used is relatively large.

[0113] In practical use, during the initial stage of drying, a low flow rate is used to intercept larger lint. Later in the drying process, as finer lint increases, a high flow rate is used to intercept the smaller lint. Finally, in the final stage, when the amount of lint is minimal, a low flow rate is used again. This method helps to conserve condensate while ensuring good filtration.

[0114] It should be noted that there is no limit to the number of spray zones 20a.

[0115] In some embodiments, as shown in Figure 2 or Figure 6, only one spray area 20a may be provided. This helps to minimize the size of the spray assembly 20 and reduce the space occupied by the spray assembly 20 in the condensation channel 10a.

[0116] In other embodiments, there are multiple spray areas 20a, each of which can spray to form a sub-water mist surface, and the sub-water mist surfaces together constitute a water mist surface.

[0117] In this way, with a fixed total area of ​​water mist surface, the area of ​​the water mist sub-surface formed in each spray area 20a can be designed to be relatively small. As a result, the flow rate requirement for the condensate flowing out of the outlet 21b is lower, which makes it easier to design the flow rate control of the condensate and the size design of the outlet 21b.

[0118] It should be noted that when there are multiple spray areas 20a, the specific location of each spray area 20a is not restricted.

[0119] For example, when projected onto a plane perpendicular to the height direction of the condenser 1, the projections of any two spray areas 20a have non-overlapping regions.

[0120] Thus, the water mist sub-surfaces sprayed from each spraying area 20a also have non-overlapping areas. This results in a larger projected area of ​​the water mist surface formed by each water mist sub-surface, which better covers the flow channel cross section and is beneficial to improving the dehumidification and filtration effect of the water mist surface on the hot and humid airflow.

[0121] In some embodiments, please refer to Figures 2 to 5 or Figures 6 to 9. The spray assembly 20 includes a liquid outlet section 21 and an impact structure 22 with a forming wall 22a. One end wall of the liquid outlet section 21 is a first structural wall 211. The impact structure 22 is disposed on the first structural wall 211 and together with the first structural wall 211 defines the liquid spraying area 20a. The liquid outlet section 21 is provided with a liquid outlet channel 21a. One end of the liquid outlet channel 21a penetrates the first structural wall 211 to form a liquid outlet 21b.

[0122] For example, the liquid outlet section 21 extends axially along the air inlet channel 10c, and the liquid outlet channel 21a also extends axially along the air inlet channel 10c.

[0123] The condensate can flow through the liquid outlet channel 21a and be sprayed out through the liquid outlet 21b. The condensate sprayed out through the liquid outlet 21b impacts the impact structure 22 to form a water mist surface.

[0124] The diameter of the liquid outlet channel 21a can be larger than that of the liquid outlet 21b. In this way, the flow resistance of the condensate in the liquid outlet channel 21a will not be too great, which helps to reduce the power loss of the condensate during the flow process and thus ensure the flow rate of the condensate at the liquid outlet 21b.

[0125] After the condensate is ejected from the outlet 21b, it impacts the impact structure 22, thereby being ejected from the periphery of the spray area 20a and appearing as a water mist.

[0126] In this embodiment, the spray area 20a is formed by the impact structure 22 and the liquid outlet section 21. The forming method of the spray area 20a is relatively simple and facilitates the production of the spray assembly 20.

[0127] In some embodiments, the liquid outlet section 21 is a metal component. That is, the liquid outlet section 21 is a component made of a metal material. The metal material can be, for example, stainless steel, copper, iron, aluminum, and various alloy materials (such as aluminum alloys).

[0128] Alternatively, the lining of the liquid outlet section 21 may be made of metal.

[0129] In this embodiment, the liquid outlet section 21 can be formed by machining and other processes, which is relatively simple. At the same time, since the surface of the metal part is relatively smooth, the inner wall of the liquid outlet channel 21a is also relatively smooth, and scale in the condensate is unlikely to remain in the liquid outlet channel 21a, thereby reducing the possibility of blockage in the liquid outlet channel 21a.

[0130] In other embodiments, the liquid outlet section 21 may also be a plastic part, which may be formed by injection molding or other processes.

[0131] The specific structure of the impact structure 22 is not limited.

[0132] In some embodiments, please refer to Figure 10 or Figure 12. The impact structure 22 includes a support portion 222 and an impact portion 221. Along the axial direction of the liquid outlet 21b, the impact portion 221 and the first structural wall 211 are spaced apart. The side of the impact portion 221 facing the first structural wall 211 is a forming wall 22a. The support portion 222 is connected to the impact portion 221 and the first structural wall 211 respectively. The support portion 222, the forming wall 22a and the first structural wall 211 together define the liquid spraying area 20a.

[0133] Here, the impact structure 22 is formed by the impact part 221 to obtain the water mist surface, while the support part 222 mainly serves to connect the first structural wall 211 and the impact part 221.

[0134] At least a portion of the condensate sprayed from the outlet 21b will sweep over the surface of the molding wall 22a. This portion of the condensate flows in multiple directions on the surface of the molding wall 22a, thereby forming a surface and being able to be sprayed out from the periphery of the molding wall 22a, thus forming a water mist surface that crosses the condensation channel 10a.

[0135] In this embodiment, the impact structure 22 can be formed into a water mist surface using a relatively simple structure, and the impact structure 22 is easy to form.

[0136] In some embodiments, referring to Figures 2 and 5, the support portion 222 has a second structural wall 22b, which is connected to the first structural wall 211 and the molding wall 22a respectively. The first structural wall 211, the molding wall 22a and the second structural wall 22b together define the spraying area 20a. The second structural wall 22b is an arc-shaped surface and is projected onto the first structural wall 211 along the axial direction of the outlet 21b. The projection of the second structural wall 22b extends circumferentially along the outlet 21b.

[0137] It should be noted that the second structural wall 22b can be an arc-shaped surface that is curved in the circumferential direction of the liquid outlet 21b; it can also be an arc-shaped surface that is curved in the axial direction of the liquid outlet 21b; or it can be an arc-shaped surface that is curved in both the circumferential and axial directions of the liquid outlet 21b. This application does not impose any limitations on this.

[0138] Here, the forming wall 22a can be a plane and can be perpendicular to the axis of the outlet 21b.

[0139] Here, the condensate sprayed from the outlet 21b impacts the second structural wall 22b. Since the second structural wall 22b is an arc-shaped surface, it can guide at least a portion of the condensate to flow towards the forming wall 22a. After flowing through the forming wall 22a, this portion of the condensate is formed into a surface, and then sprayed out through the spraying area 20a, presenting a water mist surface.

[0140] Of course, the condensate can also bypass the second structural wall 22b and directly impact the forming wall 22a.

[0141] In this embodiment, the second structural wall 22b can guide the flow of condensate, which helps to reduce the rebound phenomenon that occurs when the condensate sprayed from the outlet 21b impacts the inner wall of the spray area 20a. The condensate can be sprayed out in a larger water mist form, thus increasing the area of ​​the water mist surface and improving the condensation effect of the condenser 1. Furthermore, the second structural wall 22b can limit the spray angle of the water mist, increase the spray pressure, and enhance the spray distance, thereby improving the dandruff removal effect.

[0142] It is understood that in the above embodiment, a portion of the spray area 20a along the circumference of the outlet 21b can spray out condensate, that is, the spray area 20a is located at the outer edge of the water mist surface.

[0143] In other embodiments, please refer to Figures 6, 9 to 11. The support portion 222 has two third structural walls 222a. The two ends of any third structural wall 222a along the axial direction of the liquid outlet 21b are respectively connected to the first structural wall 211 and the impact portion 221, and the two third structural walls 222a are connected to each other along the radial direction of the liquid outlet 21b. The projection of the third structural wall 222a along the axial direction of the liquid outlet 21b is onto the first structural wall 211, and the projection of the third structural wall 222a extends along the radial direction of the liquid outlet 21b.

[0144] Here, the forming wall 22a can be an arc surface and can be perpendicular to the axis of the liquid outlet 21b.

[0145] The support part 222 has a relatively small size in the circumferential direction of the liquid outlet 21b. The spray area 20a can spray condensate at any angle (i.e., 360° angle) in the circumferential direction of the liquid outlet 21b. The spray area 20a is roughly located at the center of the water mist surface.

[0146] In this embodiment, under the condition that the flow rate of the condensate is constant, since the condensate can be sprayed out in the circumferential direction of the spray area 20a, the area of ​​the water mist surface formed is larger, which is beneficial to improving the condensation efficiency of the condenser 1.

[0147] In some embodiments, as shown in Figures 10 and 11, there are multiple support portions 222, and each support portion 222 is arranged at circumferential intervals along the liquid outlet 21b.

[0148] It should be noted that the support parts 222 can be arranged at equal intervals or at unequal intervals along the circumference of the liquid outlet 21b, and this application does not impose any restrictions on this.

[0149] For example, in the embodiments shown in Figures 10 and 11, the number of support portions 222 is three.

[0150] By providing multiple support parts 222 to support the impact part 221, when the impact part 221 is subjected to the impact of condensate, the multiple support parts 222 jointly support the impact part 221, making the impact part 221 more stable and reliable.

[0151] In some embodiments, see Figures 10 and 11, the third structural wall 222a is an arc-shaped surface.

[0152] Here, the condensate is sprayed radially from the outlet 21b through the spray area 20a. When the condensate flows through the support 222, it flows over the surface of the third structural wall 222a. The third structural wall 222a is an arc-shaped surface, which helps to reduce the flow resistance of the condensate. The condensate has a higher flow velocity when it is sprayed through the spray area 20a, and the area of ​​the water mist surface formed is larger, which helps to improve the condensation effect of the condenser 1.

[0153] In some embodiments, the projection of the forming wall 22a onto a plane perpendicular to the axial direction of the outlet 21b is a circular, elliptical, polygonal, or a shape formed by multiple arcs.

[0154] Polygons can be, for example, triangles, quadrilaterals, pentagons, etc.

[0155] For example, in the embodiments shown in Figures 10 and 11, the projection of the molding wall 22a is a shape formed by three arcs.

[0156] In this embodiment, the shape of the forming wall 22a is relatively regular, which facilitates production.

[0157] In some embodiments, referring to Figures 5 or 9, the distance between the outlet 21b and the forming wall 22a along the axial direction of the outlet 21b is not less than 3 mm. For example, it is 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm, 5 mm, etc.

[0158] Here, the distance between the forming wall 22a and the liquid outlet 21b is more suitable. The condensate has a certain impact height before reaching the forming wall 22a after being sprayed out through the liquid outlet 21b. This helps to reduce the impact of the condensate rebounding from the forming wall 22a on the condensate sprayed out through the liquid outlet 21b, thus facilitating the formation of the water mist surface.

[0159] In some embodiments, referring to Figures 2 to 5 or Figures 6 to 9, the condensation channel 10a includes a first sub-channel 10a1 and an air inlet channel 10c arranged at an angle. The air inlet channel 10c has an air inlet 10e, and the first sub-channel 10a1 is located downstream of the air inlet channel 10c. In a cross-section on a plane perpendicular to the axial direction of the air inlet channel 10c, the cross-sectional area of ​​the air inlet channel 10c is smaller than the cross-sectional area of ​​the first sub-channel 10a1.

[0160] Here, the first sub-channel 10a1 is connected to the garment processing chamber through the air inlet channel 10c.

[0161] For example, please refer to Figure 4 or Figure 8. The extension direction of the first sub-channel 10a1 is perpendicular to the axial direction of the air inlet channel 10c, and part of the structure of the spray assembly 20 is disposed in the first sub-channel 10a1.

[0162] The first sub-channel 10a1 can provide some installation space for the spray assembly 20, thereby facilitating the installation of the spray assembly 20 in the condenser 1.

[0163] For example, the first sub-channel 10a1 extends along the height direction of the condenser 1, and the air inlet channel 10c is connected to the bottom of the first sub-channel 10a1. Here, the air outlet 10b is located at the top of the condensation channel 10a. After the condensate is retained in the first sub-channel 10a1 or the air inlet channel 10c, it falls under the action of gravity, which helps to further reduce the possibility of condensate entering the heating channel 3.

[0164] It is understandable that when the airflow speed is >8-12m / s, it will lift up the water mist particles in the water mist surface and move forward with the airflow into the drying tunnel. By setting the air inlet channel 10c and the first sub-channel 10a1 at an angle, a bending structure is formed at the connection between the air inlet channel 10c and the first sub-channel 10a1. Even if the airflow carries water mist particles forward, it will slow down and bend forward when it encounters the bending structure. The water mist particles it carries will be blocked by the bending structure and will no longer flow forward. This helps to reduce the probability of water mist particles entering the heating channel 3.

[0165] It should be noted that the structure used here to block water mist particles is the windbreak wall 10d mentioned above.

[0166] The liquid outlet section 21 extends axially along the air inlet channel 10c. Thus, the liquid outlet channel 21a also extends approximately axially along the air inlet channel 10c, and the forming wall 22a is approximately perpendicular to the axial direction of the air inlet channel 10c. Since the surface containing the water mist surface is approximately parallel to the surface containing the forming wall 22a, the water mist surface can be positioned at approximately a 90° angle to the axial direction of the air inlet channel 10c. Within the confines of the air inlet channel 10c, the airflow passing over the water mist surface flows approximately axially along the air inlet channel 10c. Therefore, the water mist surface is also approximately perpendicular to the airflow direction. Projected onto a plane perpendicular to the axial direction of the air inlet channel 10c, the projected area of ​​the water mist surface is larger, thereby improving the dehumidification and filtration effects of the water mist surface on the humid and hot airflow.

[0167] In some embodiments, please refer to Figure 4 or Figure 8, the condensation channel 10a further includes a second sub-channel 10a2, which is directly connected to the first sub-channel 10a1, and the extension direction of the second sub-channel 10a2 intersects the extension direction of the first sub-channel 10a1.

[0168] In other words, the connection between the first sub-channel 10a1 and the second sub-channel 10a2 forms a corner. This corner can reduce the possibility of condensate entering the second sub-channel 10a2. The air outlet 10b is connected to the second sub-channel 10a2, which also helps to reduce the possibility of condensate entering the heating channel 3.

[0169] In some embodiments, see Figure 5 or Figure 9, the molded wall 22a is located within the air inlet channel 10c.

[0170] It is understood that the water mist surface extends roughly along the outer edge of the molding wall 22a. In this embodiment, by setting the molding wall 22a inside the air inlet channel 10c, the water mist surface formed can also be roughly located inside the air inlet channel 10c.

[0171] In some embodiments, please refer to Figures 2 to 5 or Figures 6 to 9. The housing assembly 10 includes a body 11 and a partition wall 12. The body 11 is provided with a first sub-channel 10a1 and an air inlet channel 10c. The partition wall 12 is located at one end of the air inlet channel 10c near the first sub-channel 10a1. The end wall surrounding the air inlet 10e that forms the air inlet channel 10c is a first wall 11a. The side of the partition wall 12 away from the first wall 11a is a second wall 12a. The second wall 12a constitutes the end wall at the other end of the air inlet channel 10c. The molded wall 22a is located between the first wall 11a and the second wall 12a.

[0172] Here, the area between the first wall 11a and the second wall 12a is the air inlet channel 10c.

[0173] It is understandable that when there is a gap between the outer edge of the water mist surface and the inner wall of the air inlet channel 10c (i.e., when the water mist surface does not completely cover the air inlet channel 10c), the airflow may pass through this gap, and the airflow passing through this gap will not be affected by the water mist surface.

[0174] In this embodiment, when the airflow passes through the gap between the outer edge of the water mist surface and the inner wall of the air inlet channel 10c, it impacts the partition wall 12. The partition wall 12 provides some obstruction to this part of the airflow, reducing its velocity. This helps to reduce the flow rate of the airflow passing through this gap, thereby increasing the flow rate of the airflow passing through the water mist surface. In other words, it helps to improve the overall dehumidification and filtration effect of the airflow.

[0175] In some embodiments, the water mist surface is arranged to intersect the axial direction of the air inlet channel 10c. Alternatively, the surface where the molded wall 22a is located is arranged to intersect the axial direction of the air inlet channel 10c. In this way, as the airflow flows into the condenser 1 through the air inlet channel 10c, the hot and humid airflow can easily pass through the water mist surface, thereby achieving dehumidification and filtration effects.

[0176] In some embodiments, the water mist surface is perpendicular to the axial direction of the air inlet channel 10c. Alternatively, the surface containing the molded wall 22a is perpendicular to the axial direction of the air inlet channel 10c. Thus, when projected onto a plane perpendicular to the axial direction of the air inlet channel 10c, the projected area of ​​the water mist surface is equal to the area of ​​the water mist surface itself, thereby facilitating full utilization of the water mist surface and resulting in better coverage of the air inlet channel 10c.

[0177] In some embodiments, the projected area of ​​the water mist surface is not less than 80% of the projected area of ​​the air inlet channel 10c, projected onto a plane perpendicular to the axial direction of the air inlet channel 10c. For example, it is 80%, 82%, 84%, 86%, 88%, 90%, 92%, 94%, 96%, 98%, 100%, etc.

[0178] Here, if the projected area of ​​the water mist surface accounts for less than 100% of the projected area of ​​the air inlet channel 10c, it means that the water mist surface does not completely cover the air inlet channel 10c.

[0179] It is understandable that the larger the proportion of the projected area of ​​the water mist surface to the projected area of ​​the air inlet channel 10c, the better the coverage effect of the water mist surface on the air inlet channel 10c. When the proportion reaches 100%, the airflow will pass through the water mist surface as it flows through the air inlet channel 10c. In this way, the air as a whole can be effectively dehumidified and effectively filtered.

[0180] In this embodiment, the proportion of the projected area of ​​the water mist surface in the projected area of ​​the air inlet channel 10c is controlled to be no less than 80%. The dehumidification and filtration effects of the water mist surface on the airflow can basically meet the requirements, which is conducive to ensuring the drying efficiency of clothes.

[0181] In some embodiments, see Figures 2 and 3, or Figures 6 and 7, where the projection of the spray area 20a is located within the air inlet channel 10c on a plane perpendicular to the axial direction of the air inlet channel 10c.

[0182] For example, the spray area 20a can be located within the air inlet channel 10c.

[0183] It is understandable that when the airflow in the garment processing chamber enters the condensation channel 10a through the air inlet channel 10c, it flows roughly along the axial direction of the air inlet channel 10c. In this embodiment, the formed water mist surface can better cover the air inlet channel 10c, that is, it can better cover the flow channel cross section of the drying tunnel. When the airflow passes through the position of the water mist surface in the drying tunnel, most of it can pass through the area covered by the water mist surface. As a result, the dehumidification effect of the airflow is better, and it can basically be filtered by the water mist surface, which helps to reduce the probability of lint remaining in the drying tunnel.

[0184] In some embodiments, see Figures 2 and 3, where the projection of the spray area 20a is located at the top of the air inlet duct 10c.

[0185] More specifically, the spray area 20a is located at the top of the air inlet duct 10c.

[0186] It should be noted that the surface where the air inlet 10e is located extends roughly along the height direction of the condenser 1, and the "top of the air inlet channel 10c" is roughly the position near the top wall of the air inlet channel 10c.

[0187] As in the above embodiment, when the spray area 20a is located at the outer edge of the water mist surface, the spray area 20a is positioned at the top of the air inlet channel 10c, and the water mist surface is formed below the spray area 20a. On the one hand, due to gravity, the water mist surface below the spray area 20a has a larger extension dimension, that is, the area of ​​the formed water mist surface is larger, which is beneficial to improving the condensation effect of the condenser 1. On the other hand, the area of ​​the air inlet channel 10c above the spray area 20a is smaller, and the water mist surface can cover the air inlet channel 10c as much as possible, which is beneficial to the airflow flowing through the water mist surface more, thus improving the condensation effect of the condenser 1. At the same time, it is also beneficial to improve the filtration effect of the water mist surface on the airflow.

[0188] In other embodiments, see Figures 6 and 7, where the projection of the spray area 20a is located in the middle region of the air inlet channel 10c.

[0189] More specifically, the spray area 20a is located in the middle area of ​​the air inlet channel 10c.

[0190] It should be noted that the surface where the air inlet 10e is located extends roughly along the height direction of the condenser 1, and the "middle area of ​​the air inlet channel 10c" is roughly the position near the center of the air inlet channel 10c.

[0191] As in the above embodiment, when the spray area 20a is located at the center of the water mist surface, the spray area 20a is set in the middle area of ​​the air inlet channel 10c. In this way, the water mist surface and the air inlet channel 10c are more compatible, and the water mist surface has a better coverage effect on the air inlet channel 10c. This is conducive to more airflow passing through the water mist surface, which in turn helps to improve the condensation effect of the condenser 1. At the same time, it also helps to improve the filtration effect of the water mist surface on the airflow.

[0192] In some embodiments, please refer to Figures 2 and 3, or Figures 6 and 7. The sidewall of the air inlet channel 10c includes a first arc-shaped wall 10c1, a second arc-shaped wall 10c3, and two straight extension walls 10c2. The first arc-shaped wall 10c1 and the second arc-shaped wall 10c3 are arranged opposite to each other, and the two ends of the first arc-shaped wall 10c1 are connected by the two straight extension walls 10c2 and the two ends of the second arc-shaped wall 10c3, respectively. The radius of the first arc-shaped wall 10c1 is smaller than the radius of the second arc-shaped wall 10c3. The first arc-shaped wall 10c1 is located above the second arc-shaped wall 10c3. The line connecting the two ends of the first arc-shaped wall 10c1 is the first connecting line, and the line connecting the two ends of the second arc-shaped wall 10c3 is the second connecting line.

[0193] The first arc-shaped wall 10c1 and the two straight extension walls 10c2 can both be connected by a circular arc transition, and the second arc-shaped wall 10c3 and the two straight extension walls 10c2 can also both be connected by a circular arc transition.

[0194] In other words, the air intake duct 10c is roughly pear-shaped.

[0195] The first connecting line is the line shown as L1 in Figure 3 or Figure 7, and the second connecting line is the line shown as L2 in Figure 3 or Figure 7.

[0196] In some embodiments, please refer to FIG3, the spraying area 20a is provided in the first area formed by the first arcuate wall 10c1 and the first connecting line.

[0197] As shown in Figures 2 to 5 and Figure 12, in the embodiment where the spray area 20a is located at the outer edge of the water mist surface, the condensate is sprayed out from the spray area 20a at a certain angle, and along the perpendicular bisector of the first or second line away from the first arc-shaped wall 10c1, the size of the water mist surface gradually increases in the direction where the first or second line is located.

[0198] In this embodiment, the spray area 20a is approximately located at the top of the air inlet channel 10c, that is, at the small angle end of the pear-shaped air inlet channel 10c. Within the air inlet channel 10c, along the perpendicular bisector of the first or second line away from the first arc-shaped wall 10c1, the diameter of the air inlet channel 10c gradually increases.

[0199] In other words, along the perpendicular line of the first or second line away from the first arc-shaped wall 10c1, the change in the diameter of the air inlet channel 10c is consistent with the change in the size of the water mist surface. Therefore, the water mist surface has a better coverage effect on the air inlet channel 10c.

[0200] In other embodiments, please refer to FIG7, the spraying area 20a is provided in a second area enclosed by two straight extending walls 10c2, a first connecting line and a second connecting line.

[0201] Here, the spray area 20a is approximately located in the middle of the air inlet channel 10c. This is more suitable for embodiments where the spray area 20a is located at the center of the water mist surface.
