This facilitates more uniform liquid dispersion and improves the atomization effect. Furthermore, the atomizing wall includes side walls and a top wall. Liquid sprayed from the outlet impacts the top wall and is stopped, then sprayed circumferentially to form a water mist. Simultaneously, the stop in the side wall restricts the angle and direction of the spray nozzle, making the spray more concentrated and facilitating the formation of the water mist surface, thereby improving spray efficiency.

[0047] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0048] The present application provides a clothes treatment apparatus, please refer to Figure 1 , the clothes treatment apparatus includes a drum assembly 2 and a condenser. The drum assembly 2 is provided with a clothes treatment cavity. The condenser includes a shell assembly and the spray assembly of any one of the embodiments of the present application. The shell assembly is provided with a condensing channel, and the spray assembly is used to guide the condensate into the condensing channel. The condenser is arranged on the drum assembly 2, and the condensing channel is in communication with the clothes treatment cavity.

[0049] The clothes treatment apparatus may, for example, be a clothes dryer, a washer-dryer, etc., which is not limited herein.

[0050] The inside of the drum assembly 2 has a clothes treatment cavity, and the clothes complete washing, dehydration or drying and other washing and care operations in the clothes treatment cavity.

[0051] Please refer to Figure 2 , the condenser 1 is arranged on the drum assembly 2. Exemplarily, the drum assembly 2 can include an inner drum and an outer drum, the inner drum is provided with a clothes treatment cavity, and the inner drum is rotatably supported in the outer drum, and the condenser 1 is arranged on the outer drum.

[0052] The condenser 1 is used to dehumidify the humid hot air flow generated in the clothes treatment cavity. The specific working principle is that the condenser 1 is supplied with condensate liquid, the humid hot air flow in the clothes treatment cavity enters the condenser 1, and exchanges heat with the condensate liquid in the condenser 1. The humid hot air is cooled to below the dew point, so that the humid hot air precipitates water, which is discharged from the condenser 1 together with the condensate liquid. The humid hot air after condensation becomes relatively dry cold air.

[0053] The specific type of condensate liquid is not limited. Exemplarily, the condensate liquid can be water.

[0054] The shell 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 communicated with the inside of the heating channel 3 through the air outlet 10b and communicated with the clothes treatment cavity through the air inlet 10e. That is, the air flow flowing out of the air outlet 10b will enter the heating channel 3.

[0055] The inner wall of the condensation channel 10a opposite to the air inlet 10e is a wind blocking wall 10d. The air flow in the clothes treatment cavity enters the condensation channel 10a through the air inlet 10e and changes the flow direction under the action of the wind blocking wall 10d.

[0056] The condensation channel 10a is a place where the humid hot air flow exchanges heat with the condensate liquid. The condensation channel 10a is communicated with the clothes treatment cavity, and the humid hot air flow in the clothes treatment cavity enters the condensation channel 10a and is dehumidified in the condensation channel 10a.

[0057] The spraying assembly 20 is used to guide the condensate liquid into the condensation channel 10a. During use of the clothes treatment device, the condensate liquid is supplied to the condenser 1 through a liquid supply pipeline. Specifically, the liquid supply pipeline is communicated with the spraying assembly 20, and the condensate liquid flows out of the liquid supply pipeline, flows through the spraying assembly 20 and enters the condensation channel 10a.

[0058] The spraying assembly 20 is provided with a water outlet unit, which is located in the condensation channel 10a. The condensate liquid can be sprayed out of the water outlet unit and form a water mist surface intersecting the condensation channel 10a.

[0059] It should be noted that the condensate liquid is sprayed out of the water outlet unit and presents a large number of small particles, which form a certain volume shape. The surface of the volume shape is called the water mist surface.

[0060] When the wet hot air flow with lint flows through the water mist surface, the wet hot air flow exchanges heat with the condensate in the form of water mist surface. In the related art, the condensate flows in a single or multiple columnar forms in the condenser, and the heat exchange area between the condensate and the wet hot air flow is relatively small, and the heat exchange efficiency is low, which affects the drying efficiency of the clothes. The spraying assembly 20 of the present application can spray the condensate and present it as a water mist surface, and the surface area of the water mist surface is relatively large, that is, the heat exchange area with the wet hot air flow is also relatively large, thereby improving the heat exchange efficiency between the condensate and the wet hot air flow, and further improving the drying efficiency of the clothes treatment equipment.

[0061] In addition, the lint in the wet hot air flow is slowed down, wetted, and weighted, and no longer advances with the air flow. That is, the water mist surface also has a filtering effect on the circulating air flow in the clothes treatment equipment, thereby reducing the possibility of lint remaining in the drying channel, thereby ensuring the air volume in the drying channel, and further improving the drying efficiency of the clothes treatment equipment.

[0062] It can be understood that, since the water mist surface has a filtering effect, a filter element such as a filter screen does not need to be provided in the drying channel to filter the lint, and components for cleaning the filter element are no longer needed. In this way, the components of the clothes treatment equipment are relatively few, which is beneficial to improving the production cost and production efficiency of the clothes treatment equipment.

[0063] The water outlet unit is spaced apart from the wind barrier 10d. In this way, the water mist surface sprayed by the water outlet unit is also spaced apart from the wind barrier 10d, and the air flow can pass through the water mist surface.

[0064] It should be noted that the specific manner of spacing is not limited. For example, the spraying assembly 20 can be connected to the wind barrier 10d, but there is a certain spacing between the water outlet unit of the spraying assembly 20 and the wind barrier 10d; for another example, the spraying assembly 20 can not be directly connected to the wind barrier 10d, and in this way, there is also a certain spacing between the water outlet unit and the wind barrier 10d.

[0065] It should be noted that the specific direction of spacing is not limited. For example, the water outlet unit and the wind barrier 10d are spaced apart in a direction perpendicular to the wind barrier 10d.

[0066] The specific position of the water outlet unit in the condensing 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.

[0067] It should be noted that when the condenser 1 is used in the clothes treatment equipment, the height direction of the condenser 1 is the same as the height direction of the clothes treatment equipment. For details, please refer to the schematic in Figure 2 , Figure 3 , Figure 6 or Figure 7 .

[0068] The water outlet unit is lower than the air outlet 10b, that is, the water mist surface is formed in the area below the air outlet 10b, and the condensed liquid falls under the action of gravity after being sprayed out of the water outlet unit, so that it is difficult to flow out of the condenser 1 through the air outlet 10b and into the heating channel 3. Therefore, the heat generated by the heater can be used more for heating the airflow, so as to improve the temperature of the airflow, and the airflow with a higher temperature has a better drying effect on the clothes.

[0069] In some embodiments, referring to Figure 2 , Figure 9 to Figure 11 The shell 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, and the partition wall 12 is arranged at one end of the air inlet channel 10c close to the first sub-channel 10a1; the end wall of the air inlet 10e surrounding the air inlet channel 10c is a first wall body 11a, and the side of the partition wall 12 away from the first wall body 11a is a second wall body 12a, which constitutes the end wall of the other end of the air inlet channel 10c, and the atomizing wall 202a is located between the first wall body 11a and the second wall body 12a.

[0070] Here, the area between the first wall body 11a and the second wall body 12a is the air inlet channel 10c.

[0071] It can be understood 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., the water mist surface does not completely cover the air inlet channel 10c), the airflow can pass through the gap, and the airflow passing through the gap will not be affected by the water mist surface.

[0072] In some embodiments, referring to Figure 2 The condensing channel 10a includes the air inlet channel 10c, and the condensing channel 10a communicates with the clothes treatment cavity through the air inlet channel 10c. The liquid outlet section 201 is arranged to extend along the axial direction of the air inlet channel 10c, so that the liquid outlet channel 201a is also arranged to extend along the axial direction of the air inlet channel 10c. The direction of the liquid outlet port 20b is substantially perpendicular to the axial direction of the air inlet channel 10c.

[0073] In this way, the water mist surface and the axial direction of the air inlet channel 10c can form a 90° angle as much as possible. Under the limitation of the air inlet channel 10c, the airflow flows through the water mist surface along the axial direction of the air inlet channel 10c, so that the water mist surface is substantially perpendicular to the flow direction of the airflow. When projected on the plane perpendicular to the axial direction of the air inlet channel 10c, the projection area of the water mist surface is larger, so as to improve the dehumidification effect and filtering effect of the water mist surface on the humid airflow.

[0074] In some embodiments, referring to Figure 2 , Figure 9 to Figure 11The condensing passage 10a includes a first sub-passage 10a1 and an air inlet passage 10c, the air inlet passage 10c has an air inlet 10e, and the first sub-passage 10a1 is located downstream of the air inlet passage 10c. In a cross section perpendicular to the axial direction of the air inlet passage 10c, the cross-sectional area of the air inlet passage 10c is smaller than that of the first sub-passage 10a1.

[0075] Here, the first sub-passage 10a1 is in communication with the clothes treatment cavity through the air inlet passage 10c.

[0076] Exemplarily, the extending direction of the first sub-passage 10a1 is perpendicular to the axial direction of the air inlet passage 10c, and part of the structure of the spraying assembly 20 is arranged in the first sub-passage 10a1.

[0077] The first sub-passage 10a1 can provide part of the mounting space for the spraying assembly 20, thereby facilitating the installation of the spraying assembly 20 in the condenser 1.

[0078] Exemplarily, the first sub-passage 10a1 extends along the height direction of the condenser 1, and the air inlet passage 10c is in communication with the bottom of the first sub-passage 10a1. Here, the air outlet 10b is located at the top of the condensing passage 10a, and the condensed liquid remaining in the first sub-passage 10a1 or the air inlet passage 10c falls under the action of gravity, which is conducive to further reducing the possibility of the condensed liquid entering the heating passage 3.

[0079] It can be understood that when the air flow speed is greater than 8-12 m / s, the water mist particles in the water mist surface will be lifted and move forward with the air flow into the drying channel; by arranging the air inlet passage 10c and the first sub-passage 10a1 at an angle, a bending structure is formed at the communication position of the air inlet passage 10c and the first sub-passage 10a1, even if the air flow carries the water mist particles to move forward, the air flow will slow down and bend forward when encountering the bending structure, and the carried water mist particles will be blocked by the bending structure and no longer continue to flow forward, thereby, it is conducive to reducing the probability of the water mist particles entering the heating passage 3.

[0080] The spraying assembly 20 provided by the embodiment of the present application, please refer to Figure 3 to Figure 8The spray assembly 20 comprises a liquid outlet section 201 and an impact structure 202. The liquid outlet section 201 is provided with a liquid outlet channel 201a, and an end wall of the liquid outlet section 201 at one end in the first direction is a first structure wall 201b. The liquid outlet channel 201a penetrates the first structure wall 201b to form a liquid outlet opening 201c. The impact structure 202 is arranged on the first structure wall 201b, and the impact structure 202 has an atomizing wall 202a comprising a side wall 202a2 and a top wall 202a1. The atomizing wall 202a and the first structure wall 201b jointly define a liquid spray area 20a and a liquid spray opening 20b in communication with the liquid spray area 20a. Liquid sprayed from the liquid outlet opening 201c impacts the atomizing wall 202a and is then sprayed through the liquid spray opening 20b to form a water mist surface.

[0081] The liquid outlet section 201 is a part of the spray assembly 20 responsible for transporting liquid and providing a liquid outlet channel, and is the source and initial transmission path of the liquid in the entire spraying process.

[0082] The material of the liquid outlet section 201 is not limited herein, for example, it can be a metal material to ensure structural strength and corrosion resistance, suitable for industrial environments or scenarios with higher durability requirements. It can also be an engineering plastic to reduce weight and cost.

[0083] The structure of the liquid outlet section 201 is not limited herein, for example, it can be a cylinder or a cuboid, etc.

[0084] The liquid outlet channel 201a is a pipe or space inside the liquid outlet section 201, in which the liquid flows and is directed to the liquid outlet opening 201c, ensuring that the liquid can flow out of the spray assembly 20 according to the predetermined path.

[0085] The inner surface of the liquid outlet channel 201a can be specially treated, such as polished to reduce liquid flow resistance, or coated (such as Teflon coating) to prevent liquid residue and corrosion.

[0086] The first structure wall 201b is the wall surface of the liquid outlet section 201 at one end in the first direction, and its structure plays a key role in the liquid outflow and subsequent atomization process. It not only serves as the terminal boundary of the liquid outlet channel 201a, but also cooperates with the impact structure 202 to form the liquid spray area 20a.

[0087] The impact structure 202 is a structural component arranged on the first structure wall 201b, and its main function is to impact the liquid sprayed from the liquid outlet opening 201c, thereby changing the form and spraying characteristics of the liquid to achieve atomization effect.

[0088] In some embodiments, the impact structure 202 and the liquid outlet section 201 can be integrally formed. In this way, it is beneficial to reduce parts, improve assembly efficiency, and reduce cost.

[0089] In some embodiments, the impact structure 202 and the liquid outlet section 201 can be a split structure, which is convenient for molding.

[0090] The atomization wall 202a is a part of the impact structure 202 and cooperates with the first structure wall 201b. When the liquid impacts the atomization wall 202a, the liquid is dispersed and atomized. The atomization wall 202a cooperates with the first structure wall 201b to jointly define the liquid spraying area 20a and the liquid spraying opening 20b, and determines the final spraying shape and range of the water mist.

[0091] The shape of the atomization wall 202a is not limited herein. For example, the atomization wall 202a can be a plane, a curved surface (such as a concave surface, a convex surface, or a complex free-form surface). The curved surface shape can produce different reflection and scattering effects when the liquid impacts, further optimizing the atomization effect. For example, the concave atomization wall 202a can make the liquid converge to the center after impact and then disperse, which is beneficial to form more concentrated and uniform water mist. The convex atomization wall 202a can make the liquid scatter in a more extensive direction, increasing the spraying coverage.

[0092] The liquid spraying area 20a is a spatial area defined by the atomization wall 202a and the first structure wall 201b. The liquid sprayed from the liquid outlet 201c interacts with the atomization wall 202a in this area, and is converted into a suitable state for spraying after a series of physical processes such as impact, fragmentation, and splashing.

[0093] In some embodiments, a spoiler or a deflector is arranged in the liquid spraying area 20a, so that the liquid passes through the spoiler or the deflector before impacting the atomization wall 202a, changing the flow state and velocity distribution of the liquid, and thus making the atomization more sufficient.

[0094] The liquid spraying opening 20b is an opening through which the liquid spraying area 20a communicates with the external environment. The atomized and prepared liquid is sprayed out through the liquid spraying opening 20b, forming a water mist surface with a certain diffusion angle and coverage range. The diffusion angle directly affects the coverage range and spraying uniformity of the spraying assembly 20.

[0095] For convenience of description, the first direction in the embodiments of the present application is the height direction of the liquid outlet section 201. Of course, the first direction can also be other directions, and the present application does not make specific limitation on the first direction.

[0096] The spray assembly 20 provided by the embodiments of the present application is provided with an impact structure 202 having an atomizing wall 202a, the atomizing wall 202a and the first structure wall 201b form a liquid spray area 20a and a liquid spray opening 20b, thus, the liquid sprayed from the liquid outlet 201c impacts the atomizing wall 202a, and the liquid can be scattered into small particles to form a water mist surface, which is beneficial to more uniformly disperse the liquid to be sprayed, and improve the atomizing effect. On the other hand, the atomizing wall 202a includes a side wall 202a2 and a top wall 202a1, after the liquid sprayed from the liquid outlet 201c impacts the top wall 202a1 and is stopped, the liquid is sprayed along the circumference to form a water mist. At the same time, the side wall 202a2 is partially stopped, the angle and direction of the liquid spray opening 20b are limited, so that the liquid spray is more concentrated, which is beneficial to the formation of the water mist surface, and further improves the spraying efficiency.

[0097] In some embodiments, the diffusion angle of the liquid spray opening 20b is greater than or equal to 60° and less than or equal to 180° in a plane perpendicular to the first direction.

[0098] The diffusion angle of the liquid spray opening 20b is greater than or equal to 60° and less than or equal to 180°. The specific diffusion angle of the liquid spray opening 20b is not limited here, for example, it can be 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 180°, and the like.

[0099] Controlling the diffusion angle of the liquid spray opening 20b within the above-mentioned angle range can control the water mist surface sprayed by the liquid spray opening 20b within a relatively appropriate range, under the premise of ensuring that the coverage range of the water mist surface is sufficient, the diffusion angle within this range is beneficial to improve the continuity and integrity of the water mist surface, and improve the atomizing effect.

[0100] In some embodiments, the diffusion angle of the liquid spray opening 20b is greater than or equal to 100° and less than or equal to 120°.

[0101] The diffusion angle of the liquid spray opening 20b is greater than or equal to 100° and less than or equal to 120°, for example, it can be 100°, 101°, 102°, 103°, 104°, 105°, 106°, 107°, 108°, 109°, 110°, 111°, 112°, 113°, 114°, 115°, 116°, 117°, 118°, 119°, 120°, and the like.

[0102] Please refer to Figure 3 to Figure 8The top wall 202a1 is a second structure wall 202a11, which is spaced apart from the first structure wall 201b along the first direction, and the two ends of the side wall 202a2 along the first direction are connected to the second structure wall 202a11 and the first structure wall 201b respectively. In the projection plane perpendicular to the first direction, the projection of the atomizing wall 202a covers the projection of the liquid outlet 201c, and the tangent angle between the connecting line of the side wall 202a2 and the first structure wall 201b at the two end points forms a diffusion angle.

[0103] The second structure wall 202a11 is arranged opposite to the first structure wall 201b, and factors such as the shape, area and spacing of the second structure wall 202a11 relative to the first structure wall 201b will affect the atomization effect and spray characteristics.

[0104] Exemplarily, the spacing between the second structure wall 202a11 and the first structure wall 201b can be designed as an adjustable structure. For example, a screw adjusting device is used to change the distance between the two by rotating the screw. In this way, under different working requirements, the size of the liquid spraying area 20a can be adjusted, thereby affecting the atomization degree of the liquid and the diffusion angle of the spray, and improving the adaptability and flexibility of the equipment.

[0105] The geometric characteristics (tangent angle) of the connecting line of the side wall 202a2 and the first structure wall 201b define the diffusion angle of the liquid spraying port 20b, which plays an important role in transitioning and limiting the spray angle in structure.

[0106] Here, the side wall 202a2 can be connected to the second structure wall 202a11 and the first structure wall 201b along the first direction, or at an angle to the first direction.

[0107] Exemplarily, the side wall 202a2 can be designed as an inner concave or outer convex arc structure. The inner concave arc side wall 202a2 can make the liquid show a tendency to converge to the center after impact, to a certain extent, to improve the concentration of the spray, even under a larger diffusion angle setting, to ensure the spray intensity in the central region. The outer convex arc side wall 202a2 will further expand the diffusion range of the spray, so that the spray has a wider coverage in the edge region, which is suitable for scenarios that require large-area coverage and the edge spray intensity is relatively low.

[0108] Exemplarily, a plurality of flow guide ribs can be arranged inside the side wall 202a2. The flow guide ribs are distributed along the length direction of the side wall 202a2 or at an angle with respect to the spraying direction. When the liquid flows along the side wall 202a2, the flow guide ribs can guide the liquid to form different flow patterns, such as spiral flow or stratified flow, so as to change the velocity distribution of the liquid when impacting the second structural wall 202a11 and the atomization effect, and further optimize the uniformity of the spray and the particle size distribution.

[0109] The projection of the atomization wall 202a covers the projection of the liquid outlet 201c, so that the liquid sprayed from the liquid outlet 201c can all impact on the atomization wall 202a, and the liquid cannot directly flow out of the liquid outlet 20b without being atomized, but must undergo the collision and action process with the atomization wall 202a, thereby laying a foundation for forming uniform water mist.

[0110] The diffusion angle is determined by the tangent angle of the connecting line of the side wall 202a2 and the first structural wall 201b at the two side end points, and the angle directly determines the width of the diffusion range of the water mist sprayed by the liquid outlet 20b in the horizontal direction, which is a key parameter for measuring the coverage characteristics of the spray.

[0111] The spacing between the second structural wall 202a11 and the first structural wall 201b and the connection mode of the side wall 202a2 make the liquid in the liquid spraying area 20a undergo multiple reflection, impact and breaking processes, thereby improving the atomization effect. The tangent angle of the connecting line of the side wall 202a2 and the first structural wall 201b determines the diffusion angle, that is, the diffusion angle can be controlled by the cross-sectional shape of the side wall 202a2 on the first structural wall 201b. In this way, it is beneficial to the design and processing of the diffusion angle, thereby more accurately designing and controlling the diffusion range of the spray.

[0112] In some embodiments, in the projection plane perpendicular to the first direction, the projection of the side wall 202a2 covers at least part of the projection of the liquid outlet 201c.

[0113] The side wall 202a2 is a part connecting the second structural wall 202a11 and the first structural wall 201b, and in the projection plane perpendicular to the first direction, the projection of the side wall 202a2 covers at least part of the projection of the liquid outlet 201c, and of course, the projection of the side wall 202a2 can also completely cover the projection of the liquid outlet 201c.

[0114] By covering at least part of the projection of the liquid outlet 201c by the projection of the side wall 202a2, the liquid can impact the part of the structure of the side wall 202a2, and the liquid is impacted and broken to form water mist. In addition, the liquid can also be guided by the side wall to impact the first structural wall 201b, and further be impacted and broken by the first structural wall 201b to form water mist, thereby improving the atomization effect and guiding the spraying direction of the water mist.

[0115] Referring to Figure 3 、 Figure 6 to Figure 8 The side wall 202a2 extends along a straight line and / or a curve from the first structure wall 201b to the second structure wall 202a11.

[0116] The side wall 202a2 can extend along a straight line, a curve, or a combination of a straight line and a curve from the first structure wall 201b to the second structure wall 202a11.

[0117] The side wall 202a2 extending along a straight line can be designed at different inclination angles. For example, when the side wall 202a2 is inclined at a smaller included angle with the first structure wall 201b, the flow distance of the liquid on the side wall 202a2 is relatively short after the liquid is sprayed out of the liquid outlet 201c, and the liquid impacts the second structure wall 202a11 quickly, which is beneficial to form a more concentrated spray effect. When the side wall 202a2 is inclined at a larger included angle with the first structure wall 201b, the flow distance of the liquid on the side wall 202a2 is longer, and the influence of friction and gravity during the flow process is more obvious.

[0118] When the side wall 202a2 extends along a straight line, the side wall 202a2 is a straight plane. The flow path of the liquid is relatively direct and simple during the flow from the first structure wall 201b to the second structure wall 202a11, and the shape formed by the projection on the plane perpendicular to the first direction is relatively regular, and the control of the spray angle and range is relatively intuitive and easy to calculate.

[0119] For the side wall 202a2 extending along a curve, local flow guide structures can be arranged at key positions of the curve (such as positions where the curvature changes greatly) to enhance the coverage effect of the spray and improve the uniformity of the spray in the central region.

[0120] When the side wall 202a2 extends along a curve, the side wall 202a2 is a curved plane. The flow path of the liquid is bent and changed, for example, extending along a convex curve can make the liquid gradually spread outward during the flow process, which is beneficial to increase the diffusion angle of the spray. Extending along a concave curve can make the liquid have a tendency to converge inward, which affects the concentration of the spray and the spray intensity in the central region to some extent.

[0121] The extension mode combining a straight line and a curve can comprehensively utilize the advantages of both, and different extension modes can be designed at different positions according to specific spray requirements to achieve more complex and precise control of the spray effect.

[0122] Through the straight line and / or curve extension design of the side wall 202a2, the shape and range of the spray can be flexibly adjusted according to different application scene requirements.

[0123] Referring toFigure 3 、 Figure 4 、 Figure 6 to Figure 8 The connecting line of the side wall 202a2 and the first structure wall 201b comprises a circular arc segment 20c, which surrounds the liquid outlet 201c.

[0124] The connecting line of the side wall 202a2 and the first structure wall 201b comprises a circular arc segment 20c, that is, the cross section of the side wall 202a2 on the first structure wall 201b is a circular arc, and the side wall 202a2 extends in a curved line on both sides in the direction surrounding the liquid outlet 201c.

[0125] The radius of the circular arc segment 20c is not limited here. A smaller radius of the circular arc segment 20c will make the liquid turn more sharply near the liquid outlet 201c, generating a larger centrifugal force, which is beneficial to quickly spread the liquid outward, and is suitable for scenarios that require a larger spray diffusion angle and have relatively low requirements for the uniformity of the spray edge. A larger radius of the circular arc segment 20c makes the liquid turn more gently, and the liquid speed changes less near the liquid outlet 201c, which can form a relatively concentrated spray effect with higher spray intensity in the central region.

[0126] When the liquid is sprayed from the liquid outlet 201c, due to the existence of the circular arc segment 20c, the flow direction of the liquid around the liquid outlet 201c will change along the tangent direction of the circular arc. This change makes the liquid have a more uniform outward diffusion trend in the initial stage, avoiding the phenomenon of local concentrated injection or uneven flow caused by right angles or sharp corners. The circular arc segment 20c surrounding the liquid outlet 201c acts like a guide ring, enabling the liquid to enter the liquid spraying area 20a more smoothly and uniformly after leaving the liquid outlet 201c and further interact with structures such as the side wall 202a2, laying a foundation for subsequent formation of uniform and stable spray.

[0127] Please refer to Figure 3 、 Figure 5 to Figure 8 The connecting line of the side wall 202a2 and the first structure wall 201b comprises a first straight line segment 20d and a second straight line segment 20e, and the included angle between the first straight line segment 20d and the second straight line segment 20e constitutes a diffusion angle.

[0128] The first straight line segment 20d is part of the connecting line of the side wall 202a2 and the first structure wall 201b, and its length, inclination angle and other geometric parameters together with the second straight line segment 20e determine the diffusion angle of the spray, and affect the flow direction and flow of the liquid near the liquid outlet 201c.

[0129] The second straight line segment 20e and the first straight line segment 20d jointly form a connecting line of the side wall 202a2 and the first structure wall 201b, and cooperates with the first straight line segment 20d to form a diffusion angle through the included angle between the two, and also affects the distribution and movement of the liquid in the liquid spraying area 20a.

[0130] The connecting line of the side wall 202a2 and the first structure wall 201b is composed of the first straight line segment 20d and the second straight line segment 20e, and the included angle between the two straight lines is the diffusion angle. After the liquid is sprayed from the liquid outlet 201c, it is divided and flows in the directions determined by the first straight line segment 20d and the second straight line segment 20e. Since the two straight lines form an included angle, the liquid will be dispersed in different directions when it leaves the liquid outlet 201c, and the size of the included angle directly determines the width of the liquid dispersion range. For example, if the included angle is small, the liquid diffusion range is relatively narrow, and the spray is more concentrated. If the included angle is large, the liquid will spread to a wider range, forming a larger area of spray coverage. This structure enables the diffusion angle of the spray to be accurately controlled by adjusting the relative positional relationship (i.e. the size of the included angle) of the first straight line segment 20d and the second straight line segment 20e.

[0131] Please refer to Figure 3 to Figure 4 , Figure 6 to Figure 8 , the side wall 202a2 includes a circular arc segment 20c surrounding the liquid outlet 201c, and the two ends of the circular arc segment 20c are smoothly connected with the first straight line segment 20d and the second straight line segment 20e respectively.

[0132] The side wall 202a2 includes a circular arc segment 20c surrounding the liquid outlet 201c, and the two ends of the circular arc segment 20c are smoothly connected with the first straight line segment 20d and the second straight line segment 20e respectively. When the liquid is sprayed from the liquid outlet 201c, it first contacts the circular arc segment 20c. Due to the guiding effect of the circular arc, the liquid begins to spread outward along the tangent direction of the circular arc, avoiding the phenomenon of local concentrated spraying or uneven flow caused by right angles or sharp corners. Then, the liquid continues to flow along the smoothly connected circular arc segment 20c, the first straight line segment 20d and the second straight line segment 20e, and further divides and spreads in the directions determined by the first straight line segment 20d and the second straight line segment 20e, thereby forming a spray with a specific diffusion angle and uniformity. This structure combines the uniform flow advantage of the circular arc segment 20c with the diffusion angle control advantage of the first straight line segment 20d and the second straight line segment 20e, enabling the spray to be precisely controlled in the diffusion range while ensuring uniformity.

[0133] Please refer to Figure 3 and Figure 6 , the second structure wall 202a11 is parallel to the first structure wall 201b.

[0134] The second structure wall 202a11 is parallel to the first structure wall 201b. In this structure, the liquid sprayed from the liquid outlet 201c flows in the liquid spraying area 20a between the first structure wall 201b and the second structure wall 202a11. Since the two walls are parallel, the space constraint on the liquid is relatively uniform.

[0135] The flow path of the liquid before it impacts the second structure wall 202a11 is relatively stable and predictable, and the velocity component of the liquid in the direction perpendicular to the wall surface changes regularly. For example, when the liquid flows between two parallel walls, it will not produce complex vortexes or turbulence due to irregular angles of the wall surfaces (compared to the case of non-parallel wall surfaces), which is conducive to the liquid impacting the second structure wall 202a11 in a more consistent state, thereby providing a basic condition for forming a uniform atomization effect.

[0136] In some embodiments, referring to Figure 3 and Figure 7 , the second structure wall 202a11 is a slope, and along the direction away from the side wall 202a2, the distance between the second structure wall 202a11 and the liquid outlet 201c in the first direction gradually increases.

[0137] When the liquid is sprayed from the liquid outlet 201c, in the process of flowing towards the second structure wall 202a11, due to the slope design of the second structure wall 202a11, the space faced by the liquid in the direction perpendicular to the first direction gradually increases.

[0138] The liquid near the side wall 202a2 will contact the second structure wall 202a11 in a relatively short vertical distance, while the liquid away from the side wall 202a2 will move in a larger vertical space before interacting with the second structure wall 202a11.

[0139] This difference causes the flow speed of the liquid at different positions and the angle of impact on the second structure wall 202a11 to change, thereby affecting the atomization effect and the distribution of the spray. The liquid near the side wall 202a2 will form a relatively concentrated and slightly larger particle spray portion because it quickly contacts the second structure wall 202a11.

[0140] The liquid away from the side wall 202a2 will form a more dispersed and finer particle spray portion after a long flow path and a large space change before impacting the second structure wall 202a11, ultimately forming an overall spray effect with different spray characteristics distribution.

[0141] Referring to Figure 3 and Figure 8 , the second structure wall 202a11 is a curved surface, and along the direction away from the side wall 202a2, the distance between the second structure wall 202a11 and the liquid outlet 201c in the first direction gradually increases.

[0142] The second structure wall 202a11 is designed as a curved surface, and in the direction away from the side wall 202a2, the distance between the second structure wall 202a11 and the liquid outlet 201c in the first direction gradually increases. After the liquid is sprayed from the liquid outlet 201c, due to the curved surface characteristics of the second structure wall 202a11, the space change experienced by the liquid in the process of flowing to it is continuous and nonlinear.

[0143] Compared with a plane or a simple inclined surface, the curved surface makes the flow path length and the degree of constraint experienced by the liquid at different positions change continuously. Near the side wall 202a2, the contact distance of the liquid with the curved surface is relatively short, and the liquid is affected by the curved surface in a short path, which can form a relatively concentrated and directional spray part.

[0144] As it moves away from the side wall 202a2, the liquid needs to interact with the curved surface in a larger spatial span, and the change of its flow speed and direction is more complex, which can produce a more dispersed and finer spray part.

[0145] Exemplarily, the second structure wall 202a11 and the side wall 202a2 are smoothly transitioned to form a complete curved surface, which is beneficial to the processing of the atomization wall 202a.

[0146] This structure makes the spray exhibit different characteristics in different regions, and overall forms a spray effect with gradient change, which gradually transitions from the relatively concentrated region near the side wall 202a2 to the more widely dispersed region away from the side wall 202a2.

[0147] In some embodiments, referring to Figure 3 to Figure 8 , the distance between the liquid outlet 201c and the side wall 202a2 in the first direction is L1, and the distance between the liquid outlet 201c and the second structure wall 202a11 in the first direction is L2, and the ratio of L1 to L2 is greater than or equal to 0.3 and less than or equal to 0.7.

[0148] The ratio of the distance L1 between the liquid outlet 201c and the side wall 202a2 in the first direction and the distance L2 between the liquid outlet 201c and the second structure wall 202a11 in the first direction can be 0.3, 0.32, 0.34, 0.36, 0.38, 0.4, 0.42, 0.44, 0.46, 0.48, 0.5, 0.52, 0.54, 0.56, 0.58, 0.6, 0.62, 0.64, 0.66, 0.68, 0.7, etc.

[0149] When the ratio of L1 to L2 is in this range, after the liquid is sprayed from the liquid outlet 201c, in the process of flowing to the side wall 202a2 and the second structure wall 202a11, the proportional spatial distance it experiences in the first direction is relatively fixed.

[0150] By defining the ratio of L1 to L2 within the above range, the interaction of the liquid flowing out of the liquid outlet 201c with the side wall 202a2 and the second structure wall 202a11 can be accurately controlled, so as to accurately control the diffusion angle, uniformity, atomization degree and other characteristics of the spray.

[0151] In some embodiments, referring to Figure 9 to Figure 11 , the projection of the liquid spraying area 20a is located at the top of the air inlet channel 10c.

[0152] More specifically, the liquid spraying area 20a is located at the top of the air inlet channel 10c.

[0153] It should be noted that the face where the air inlet 10e is located extends approximately along the height direction of the condenser 1, and the "top of the air inlet channel 10c" is approximately the position close to the top wall of the air inlet channel 10c.

[0154] Exemplarily, the side wall 202a2 of the air inlet channel 10c includes a first arc-shaped wall 10c1, a second arc-shaped wall 10c3, and two linear extension walls 10c2, the first arc-shaped wall 10c1 and the second arc-shaped wall 10c3 are oppositely arranged, and the two ends of the first arc-shaped wall 10c1 are connected by the two ends of the two linear extension walls 10c2 and 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 connecting line between the two ends of the first arc-shaped wall 10c1 is the first connecting line, and the connecting line between the two ends of the second arc-shaped wall 10c3 is the second connecting line.

[0155] In some embodiments, referring to Figure 9 , the connecting line between the midpoint of the first connecting line and the midpoint of the second connecting line is the third connecting line, and the direction of the third connecting line intersects with the height direction of the condenser 1.

[0156] The first connecting line is the line C1 shown in Figure 9 , the second connecting line is the line C2 shown in Figure 9 , and the third connecting line is the line C3 shown in Figure 9 .

[0157] The first arc-shaped wall 10c1 and the two linear extension walls 10c2 can be connected by a circular arc transition, and the second arc-shaped wall 10c3 and the two linear extension walls 10c2 can also be connected by a circular arc transition.

[0158] That is, the shape of the air inlet channel 10c is approximately pear-shaped.

[0159] In some embodiments, referring to Figure 9The first area is formed by the first arc-shaped wall 10c1 and the first line, and the liquid spraying area 20a can be arranged in the first area.

[0160] In some embodiments, referring to Figure 9 The second area is formed by the two straight walls 10c2, the first line and the second line, and the liquid spraying area 20a can be arranged in the first area.

[0161] In some embodiments, the projection of the liquid spraying area 20a is located at the top of the air inlet channel 10c, that is, the spraying assembly 20 is arranged as close to the first arc-shaped wall 10c1 as possible.

[0162] Here, the projection of the liquid spraying area 20a is located at the top of the air inlet channel 10c, that is, the spraying assembly 20 is arranged in the first area.

[0163] As described in the above embodiments, when the liquid spraying area 20a is located at the outer edge of the water mist surface, the liquid spraying area 20a is arranged at the top of the air inlet channel 10c, and the water mist surface is formed below the liquid spraying area 20a. On the one hand, due to the effect of gravity, the water mist surface below the liquid spraying area 20a extends larger in size, that is, the formed water mist surface has a larger area, thereby facilitating the improvement of the condensation effect of the condenser 1. On the other hand, the area of the air inlet channel 10c above the liquid spraying area 20a is smaller, and the water mist surface can cover the air inlet channel 10c as much as possible, thereby facilitating the airflow to flow through the water mist surface more, thereby facilitating the improvement of the condensation effect of the condenser 1, and also facilitating the improvement of the filtering effect of the water mist surface on the airflow.

[0164] In some embodiments, referring to Figure 9 to Figure 11 The shell assembly 10 includes a liquid inlet cavity 10f arranged on the side of the spraying assembly 20 away from the liquid outlet 201c and in communication with the liquid outlet channel 201a. The liquid inlet cavity 10f can provide the required condensate for the spraying assembly 20 to form a water mist surface.

[0165] In order for the condensate sprayed out of the liquid outlet 201c to form a water mist surface, the diameter of the liquid outlet 201c is generally relatively small. During long-term use, the liquid outlet 201c may be blocked. After the liquid outlet 201c is blocked, the condensate in the liquid inlet cavity 10f cannot be discharged to achieve the condensation effect. After the liquid inlet cavity 10f is filled with condensate, the condensate in the liquid supply pipeline of the liquid inlet cavity 10f cannot enter the liquid inlet cavity 10f, so that the pressure inside the liquid supply pipeline cannot be released, which may cause the liquid supply pipeline to burst, posing a safety risk and reducing the reliability of the condenser 1.

[0166] In some embodiments, a pressure relief device 30 is arranged in the liquid inlet cavity 10f, and works when the liquid outlet 201c is blocked and unable to normally spray the condensed liquid, so that the pressure in the liquid inlet cavity 10f can be released, thereby facilitating to reduce the probability of burst of the liquid supply pipeline in communication with the liquid inlet cavity 10f, and further facilitating to improve the reliability of the condenser 1.

[0167] Exemplarily, the shell assembly 10 is further provided with a pressure relief channel 10g, two ends of the pressure relief channel 10g being in communication with the liquid inlet cavity 10f and the outside of the liquid inlet cavity 10f respectively. The pressure relief device 30 is at least partially arranged in the pressure relief channel 10g, and is used to selectively open or block the pressure relief channel 10g. When the liquid outlet 201c normally sprays the condensed liquid, the pressure relief device 30 blocks the pressure relief channel 10g, so as to guarantee sufficient pressure in the liquid inlet cavity 10f, and make the condensed liquid sprayed from the liquid outlet 201c. When the liquid outlet 201c is blocked or the pressure in the liquid inlet cavity 10f is increased due to other reasons, the pressure relief device 30 opens the pressure relief channel 10g, and communicates the liquid inlet cavity 10f and the outside of the liquid inlet cavity 10f through the pressure relief channel 10g, so as to reduce the pressure inside the liquid inlet cavity 10f, protect the liquid supply pipeline in communication with the liquid inlet cavity 10f, and improve the reliability of the condenser 1.

[0168] The specific structure of the pressure relief device 30 is not limited here, and can be a pressure relief valve or other pressure relief structure, etc.
