Description

Technical Field

[0001] This application relates to the field of garment washing and care technology, and in particular to a condenser and garment processing equipment. Background Technology

[0002] 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.

[0003] 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. Utility Model Content

The impact structure is disposed on the first structural wall and defines the spray area with the first structural wall.

[0022] In some embodiments, the impact structure includes a support portion and an impact portion. Along the axial direction of the liquid outlet, the impact portion and the first structural wall are spaced apart. The side of the impact portion facing the first structural wall is the molding wall. The support portion is connected to the impact portion and the first structural wall respectively. The support portion, the molding wall, and the first structural wall together define the liquid spraying area.

[0023] In some embodiments, the support portion has a second structural wall that is connected to the first structural wall and the molding wall, respectively, and the first structural wall, the molding wall and the second structural wall together define the spraying area;

[0024] The second structural wall is an arc-shaped surface and is projected onto the first structural wall along the axial direction of the liquid outlet. The projection of the second structural wall extends circumferentially along the liquid outlet.

[0057] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0058] This application provides a garment processing device; please refer to [link / reference]. Figure 1 The garment processing equipment includes a drum assembly 2 and a condenser 1 according to any embodiment of this application.

[0059] Clothing processing equipment may include, for example, dryers, washer-dryer combos, etc., and this application does not limit it.

[0060] The drum assembly 2 has a garment processing chamber inside, where garments undergo washing, dehydration, or drying processes.

[0061] 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.

[0062] 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.

[0063] There is no limitation on the specific type of condensate. For example, the condensate can be water.

[0064] 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.

[0065] 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.

[0066] In view of this, embodiments of this application also provide a condenser, please refer to... Figure 2 or Figure 6 The condenser 1 includes a housing assembly 10 and a spray assembly 20.

[0067] See also Figures 2 to 5 ,or Figures 6 to 9 The housing assembly 10 is provided with a condensation channel 10a, which includes a first sub-channel 10a1 and an air inlet channel 10c. 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. After the condenser 1 is used in the garment processing equipment, the first sub-channel 10a1 is connected to the garment processing chamber through the air inlet channel 10c.

[0068] The inner wall of the condensation channel 10a, opposite to the air inlet 10e, is a baffle wall 10d. Specifically, the condensation channel 10a also includes a first sub-channel 10a1 located downstream of the air inlet channel 10c, and the baffle wall 10d is the inner wall of the first sub-channel 10a1. When the airflow in the garment processing chamber passes near the connection between the air inlet channel 10c and the first sub-channel 10a1, its flow direction is changed by the action of the baffle wall 10d.

[0069] The condensation channel 10a is where the hot and humid airflow exchanges heat with the condensate. The hot and humid airflow in the clothing processing chamber enters the condensation channel 10a and is dehumidified within it.

[0070] Furthermore, the housing assembly 10 is also provided with an air outlet 10b. After the condenser 1 is used in the clothing processing equipment, the airflow flowing out through the air outlet 10b will enter the heating channel 3.

[0071] Please see Figure 2 or Figure 6 In the height direction of condenser 1, the liquid spraying area 20a is lower than the air outlet 10b.

[0072] 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 [link / reference needed] for details. Figure 2 , Figure 3 , Figure 6 or Figure 7 The illustration is shown in the image.

[0073] 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.

[0074] Please see Figures 3 to 5 ,or Figures 7 to 9 The spray assembly 20 is provided with a spray area 20a, through which condensate can be sprayed out and form a water mist surface that crosses the condensation channel 10a.

[0075] It should be noted that the condensate is sprayed out from the spray area 20a 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] The spraying area 20a and the windbreak wall 10d are spaced apart. In this way, the water mist surface sprayed from the spraying area 20a and the windbreak wall 10d can also be spaced apart, which facilitates the airflow passing through the water mist surface.

[0080] 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 spray area 20a 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 spray area 20a and the windbreak wall 10d.

[0081] It should be noted that the specific direction of the spacing is not limited. For example, the spray area 20a and the windbreak wall 10d are spaced apart in a direction perpendicular to the windbreak wall 10d.

[0082] Please see Figures 2 to 4 ,or Figures 6 to 8 The cross-sectional area at the junction of the first sub-channel 10a1 and the air inlet channel 10c is larger than the cross-sectional area of ​​the air inlet channel 10c. Here, the baffle wall 10d is the inner wall of the first sub-channel 10a1. That is to say, after the airflow enters the first sub-channel 10a1 through the air inlet channel 10c, the flow velocity is reduced. This helps to reduce the resistance loss encountered by the airflow in the condensation channel 10a, thereby helping to ensure airflow and improve the drying efficiency of clothes.

[0083] The water mist surface is set at an angle to the axial direction of the air inlet channel 10c. Along the axial direction of the air inlet channel 10c, the side of the water mist surface away from the windbreak wall 10d does not extend beyond the surface where the air inlet 10e is located. In other words, the water mist surface is located within the condensation channel 10a. That is, along the axial direction of the air inlet channel 10c, from one side of the windbreak wall 10d towards the side where the air inlet 10e is located, the water mist surface does not extend beyond the surface where the air inlet 10e is located.

[0084] It is understandable that when the airflow in the garment processing chamber enters the first sub-channel 10a1 through the air inlet channel 10c, it flows roughly along the axial direction of the air inlet channel 10c. Since the water mist surface is set at an angle to the axial direction of the air inlet channel 10c, the airflow also needs to pass through the water mist surface during the process of passing through the air inlet channel 10c. The water mist surface can effectively dehumidify and filter the airflow.

[0085] The condenser in this embodiment controls the side of the water mist surface away from the windbreak wall 10d to a position not exceeding the surface where the air inlet 10e is located. When the airflow in the clothing processing chamber enters the air inlet channel 10c through the air inlet 10e, it can pass through the water mist surface more, thereby improving the overall dehumidification and filtration effect of the airflow, which in turn helps to improve the drying efficiency of the clothes. At the same time, the edge of the water mist surface is also located in the condensation channel, so the condensate will not enter the clothing processing chamber through the air inlet 10e, thereby helping to improve the problem of condensate entering the clothing processing chamber and wetting the clothes.

[0086] In some embodiments, the water mist surface is located within the air inlet channel 10c.

[0087] Understandably, since the air inlet channel 10c is located upstream of the condenser channel 10a, on the one hand, as the airflow passes through the water mist surface, it helps reduce the possibility of condensate being impacted by the airflow and entering the heating channel 3. The heat generated by the heater can be used more to heat the airflow, thus obtaining a higher temperature dry hot airflow, which helps improve the drying efficiency of clothes. On the other hand, upstream of the condenser channel 10a, the cross-sectional area of ​​the air inlet channel 10c is relatively small. Under the condition that the area of ​​the water mist surface is fixed, the water mist surface has a better coverage effect on the cross-sectional area of ​​the condenser channel 10a within the air inlet channel 10c, which helps the airflow pass through the water mist surface more, thereby improving the overall dehumidification and filtration effect of the airflow, which in turn helps improve the drying efficiency of clothes.

[0088] In other embodiments, the water mist surface is located within the first sub-channel 10a1. In this way, at least a portion of the airflow can also pass through the water mist surface, thereby completing filtration and dehumidification.

[0089] In some embodiments, a portion of the water mist surface is located within the air inlet channel 10c, and another portion is located within the first sub-channel 10a1. In this way, at least a portion of the airflow can also pass through the water mist surface, thereby completing filtration and dehumidification.

[0090] 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 the first wall 11a. The side of the partition wall 12 away from the first wall 11a is the second wall 12a. The second wall 12a constitutes the end wall at the other end of the air inlet channel 10c. The water mist surface is located between the first wall 11a and the second wall 12a.

[0091] Here, the area between the first wall 11a and the second wall 12a is the air inlet channel 10c.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] The angle between the water mist surface and the axial direction of the air inlet channel 10c is not limited.

[0099] In some embodiments, the angle between the water mist surface and the axial direction of the air inlet channel 10c is an acute angle.

[0100] In other embodiments, the water mist surface is perpendicular to the axis of the air inlet channel 10c. Thus, when projected onto a plane perpendicular to the axis 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, which helps to make full use of the water mist surface and makes the water mist surface cover the air inlet channel 10c better.

[0101] In some embodiments, please refer to Figures 3 to 5 ,or Figures 7 to 9 The spray assembly 20 is provided with a liquid outlet channel 21a. The liquid outlet channel 21a and the spray area 20a are arranged and connected along the axial direction of the air inlet channel 10c. The inner wall of the spray area 20a includes a forming wall 22a. Along the axial direction of the liquid outlet channel 21a, the forming wall 22a and the liquid outlet channel 21a are spaced apart. The forming wall 22a is used to form at least a portion of the water mist surface. The forming wall 22a does not extend beyond the surface where the air inlet 10e is located. That is, along the axial direction of the air inlet channel 10c, from one side of the windbreak wall 10d to the side where the air inlet 10e is located, the forming wall 22a does not extend beyond the surface where the air inlet 10e is located.

[0102] Here, the condensate is linearly ejected along the axial direction of the liquid outlet channel 21a. 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 ejected from the spray area 20a through the outer edge of the forming wall 22a.

[0103] It is understood that the water mist surface extends roughly along the outer edge of the molding wall 22a. In this embodiment, by controlling the molding wall 22a to be located at a position not exceeding the surface where the air inlet 10e is located, the water mist surface formed can also be located roughly within the surface where the air inlet 10e is located.

[0104] Preferably, the forming wall is located within the air inlet channel 10c, so that the water mist surface formed can also be located approximately within the air inlet channel 10c.

[0105] In some embodiments, along the axial direction of the air inlet channel 10c, the distance between the molded wall 22a and the windbreak wall 10d is a first distance, and the distance between the air inlet 10e and the windbreak wall 10d is a second distance, with the ratio of the first distance to the second distance being not less than 0.3. For example, it can be 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, etc.

[0106] It is understandable that when the airflow leaves the air inlet channel 10c and enters the first sub-channel 10a1, the airflow still flows roughly along the axial direction of the air inlet channel 10c in the front section of the first sub-channel 10a1. In this embodiment, there is a certain gap between the formed water mist surface and the windbreak wall 10d, so that the airflow can pass through the water mist surface before touching the windbreak wall 10d. This is beneficial for the water mist surface to dehumidify and filter the airflow.

[0107] 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. The liquid outlet section 21 extends axially along the air inlet channel 10c. One end wall of the liquid outlet section 21 is a first structural wall 211. A liquid outlet channel 21a is provided in the liquid outlet section 21. The liquid outlet channel 21a penetrates the first structural wall 211 to form a liquid outlet 21b. The impact structure 22 is provided on the first structural wall 211 and defines the spray area 20a with the first structural wall 211.

[0108] 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.

[0109] The liquid outlet channel 21a can also extend axially along the air inlet 10e. In this way, the flow resistance in the liquid outlet channel 21a is smaller, which helps to ensure the flow rate of the condensate at the liquid outlet 21b.

[0110] 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.

[0111] The diameter of the liquid outlet channel 21a can be larger than the diameter 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.

[0112] 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.

[0113] 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.

[0114] The specific structure of the impact structure 22 is not limited.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] In some embodiments, please refer to Figure 2 and Figure 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 liquid outlet 21b. The projection of the second structural wall 22b extends circumferentially along the liquid outlet 21b.

[0120] 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.

[0121] Here, the forming wall 22a can be a plane and can be perpendicular to the axis of the outlet 21b.

[0122] 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.

[0123] Of course, the condensate can also bypass the second structural wall 22b and directly impact the forming wall 22a.

[0124] 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.

[0125] 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.

[0126] In other embodiments, please refer to Figure 6 , Figures 9 to 11 The support 222 has two third structural walls 222a. Each third structural wall 222a is connected to the first structural wall 211 and the impact part 221 at both ends along the axial direction of the outlet 21b, and the two third structural walls 222a are connected to each other at both ends along the radial direction of the outlet 21b. The projection of the third structural wall 222a onto the first structural wall 211 along the axial direction of the outlet 21b is the same as the projection of the third structural wall 222a onto the radial direction of the outlet 21b.

[0127] Here, the forming wall 22a can be an arc surface and can be perpendicular to the axis of the liquid outlet 21b.

[0128] 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.

[0129] 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.

[0130] In some embodiments, please refer to Figure 10 and Figure 11 There are multiple support parts 222, and each support part 222 is arranged at intervals along the circumference of the liquid outlet 21b.

[0131] 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.

[0132] For example, Figure 10 and Figure 11 In the embodiment shown, there are three support portions 222.

[0133] 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.

[0134] In some embodiments, please refer to Figure 10 and Figure 11 The third structural wall 222a is an arc-shaped surface.

[0135] 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.

[0136] In some embodiments, please refer to Figure 4 or Figure 8 The extension direction of the first sub-channel 10a1 intersects the axial direction of the air inlet channel 10c, and part of the structure of the spray assembly 20 is located in the first sub-channel 10a1.

[0137] The first sub-channel 10a1 can provide some installation space for the spray assembly 20, thereby facilitating the installation of the spray assembly 20 within the condenser 1.

[0138] After the airflow enters the first sub-channel 10a1 through the air inlet channel 10c, its flow direction will change. The condensate carried by the airflow impacting the water mist surface can more easily come into contact with the inner wall of the first sub-channel 10a1 and thus remain in the first sub-channel 10a1. This helps to reduce the possibility of condensate entering the heating channel 3.

[0139] 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, and the condensate is retained in the first sub-channel 10a1 and falls under the action of gravity, which helps to further reduce the possibility of condensate entering the heating channel 3.

[0140] In some embodiments, please refer to Figure 4 or Figure 8 The condensation channel 10a also includes a second sub-channel 10a2 located downstream of the first sub-channel 10a1. The second sub-channel 10a2 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.

[0141] 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.
