[0048] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0049] The embodiments of the present application provide a clothes treatment apparatus, please refer to Figure 1 The clothes treatment apparatus includes a drum assembly 2 and a condenser 1 of any one of the embodiments of the present application.

[0050] The clothes treatment apparatus may, for example, be a clothes dryer, a washer-dryer, etc., which is not limited herein.

[0051] The inner part of the drum assembly 2 has a laundry treatment cavity in which the laundry is subjected to washing, dehydration or drying, etc.

[0052] 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 the laundry treatment cavity and is rotatably supported in the outer drum, and the condenser 1 is arranged on the outer drum.

[0053] The condenser 1 is used for dehumidifying the humid hot air flow generated in the laundry treatment cavity. The specific working principle is that the condenser 1 is filled with condensing liquid, the humid hot air flow in the laundry treatment cavity enters the condenser 1 and exchanges heat with the condensing liquid in the condenser 1, the humid hot air is cooled to below the dew point, so that the humid hot air precipitates water, and the humid hot air after condensation becomes relatively dry cold air together with the condensing liquid and is discharged from the condenser 1.

[0054] The specific type of the condensing liquid is not limited. Exemplarily, the condensing liquid can be water.

[0055] A heating channel 3 is arranged downstream of the condenser 1, the space of the heating channel 3 and the inner space of the condenser 1 together constitute a drying channel of the laundry treatment equipment, and a fan and a heater are arranged in the heating channel 3. The dry cold air flowing out of the condenser 1 flows through the heater, the heater heats the dry cold air and makes it become dry hot air, and the dry hot air returns to the laundry treatment cavity for drying the laundry. In this way, the air flow circulates between the laundry treatment cavity and the drying channel, realizing continuous drying of the laundry, and the fan provides power for the circulation of the air flow.

[0056] It can be understood that in the process of circulating flow, the air flow may carry the lint of the laundry into the drying channel. If no filter screen is arranged in the drying channel, the lint will adhere to the drying channel and block the drying channel, and will breed bacteria if not cleaned for a long time. If a filter screen is arranged in the drying channel to filter the lint in the air flow, the filter screen is difficult to take out for cleaning because it is arranged in the drying channel. Even if the filter screen is cleaned in the drying channel, the cleaning liquid is difficult to uniformly cover the filter screen, so that part of the lint may remain on the filter screen and cannot be cleaned, which will block the drying channel for a long time, cause the air flow to decrease, and affect the drying efficiency, etc.

[0057] Therefore, the present application further provides a condenser, please refer to Figure 2 or Figure 6 The condenser 1 includes a shell assembly 10 and a spraying assembly 20.

[0058] The shell assembly 10 is provided with a condensing channel 10a having an air outlet 10b and an air inlet 10c. Specifically, the condensing channel 10a is in communication with the interior of the heating channel 3 through the air outlet 10b and with the clothes treatment cavity through the air inlet 10c. That is, the airflow flowing out of the air outlet 10b enters the heating channel 3.

[0059] The inner wall of the condensing channel 10a opposite to the air inlet 10c is a wind blocking wall 10d. The airflow in the clothes treatment cavity changes direction under the action of the wind blocking wall 10d after entering the condensing channel 10a through the air inlet 10c.

[0060] The condensing channel 10a is a place where the hot and humid airflow exchanges heat with the condensate. The condensing channel 10a is in communication with the clothes treatment cavity. The hot and humid airflow in the clothes treatment cavity enters the condensing channel 10a and dehumidifies in the condensing channel 10a.

[0061] The spraying assembly 20 is used to guide the condensate into the condensing channel 10a. During use of the clothes treatment device, the condensate is supplied to the condenser 1 through a liquid supply pipeline. Specifically, the liquid supply pipeline is in communication with the spraying assembly 20. The condensate flows out of the liquid supply pipeline, flows through the spraying assembly 20, and enters the condensing channel 10a.

[0062] Please refer to Figures 3 to 5 , or Figures 7 to 9 The spraying assembly 20 is provided with a liquid spraying area 20a. The condensate can be sprayed out of the liquid spraying area 20a and form a water mist surface that crosses the condensing channel 10a.

[0063] It should be noted that the condensate is sprayed out of the liquid spraying area 20a and presents a large number of small particles. These small particles form a certain volume shape. The surface of the volume shape is called the water mist surface.

[0064] When the hot and humid airflow with lint flows through the water mist surface, the hot and humid airflow exchanges heat with the condensate that presents a water mist surface. In the related art, the condensate flows in a single column or multiple columns in the condenser. The heat exchange area between the condensate and the hot and humid airflow 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 a water mist surface. The surface area of the water mist surface is relatively large, that is, the heat exchange area with the hot and humid airflow is also relatively large, thereby improving the heat exchange efficiency between the condensate and the hot and humid airflow, and further improving the drying efficiency of the clothes treatment device.

[0065] In addition, the lint in the hot and humid airflow is slowed down, wetted, and weighted, and no longer advances with the airflow. That is, the water mist surface also has a filtering effect on the circulating airflow in the clothes treatment device. Therefore, it is beneficial to reduce 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 device.

[0066] It can be understood that, since the water mist surface has the filtering effect, the filter element such as the filter screen does not need to be arranged in the drying channel to filter the lint, and the components for cleaning the filter element are no longer needed. In this way, the components of the clothes treatment apparatus are relatively less, which is beneficial to improve the production cost and production efficiency of the clothes treatment apparatus.

[0067] The liquid spraying area 20a is arranged in a spaced manner with the wind barrier 10d. In this way, the water mist surface sprayed through the liquid spraying area 20a can also be arranged in a spaced manner with the wind barrier 10d, which facilitates the airflow to pass through the water mist surface.

[0068] It should be noted that the specific manner of the spaced arrangement 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 liquid spraying area 20a 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 liquid spraying area 20a and the wind barrier 10d.

[0069] It should be noted that the specific direction of the spaced arrangement is not limited. Exemplarily, the liquid spraying area 20a and the wind barrier 10d are arranged in a spaced manner along a direction perpendicular to the wind barrier 10d.

[0070] Please refer to Figure 5 or Figure 9 The spraying assembly 20 is further provided with a liquid outlet 21b, the liquid outlet 21b and the liquid spraying area 20a are communicated, and the condensed liquid sequentially flows through the liquid outlet 21b and the liquid spraying area 20a.

[0071] Here, the condensed liquid is linearly sprayed along the axial direction of the liquid outlet 21b, and at this time, the condensed liquid has a certain flow rate, and the linear condensed liquid impacts on the inner wall of the liquid spraying area 20a, and is then sprayed from the liquid spraying area 20a and can present the form of the water mist surface.

[0072] It can be understood that, in order to ensure that the condensed liquid sprayed through the liquid spraying area 20a presents the form of the water mist surface, it is necessary to ensure that the condensed liquid sprayed through the liquid outlet 21b has a certain flow rate.

[0073] It can be understood that, in the case that the flow of the condensed liquid in the liquid supply pipeline is constant, the smaller the diameter of the liquid outlet 21b is, the greater the flow rate of the condensed liquid sprayed through the liquid outlet 21b is, so that the condensed liquid sprayed through the liquid spraying area 20a is more likely to present a water mist surface form. Of course, the diameter of the liquid outlet 21b cannot be too small, and in the case that the diameter is too small, the scale and other impurities in the condensed liquid can cause the liquid outlet 21b to be blocked, thereby affecting the reliability of the spray assembly 20. Therefore, the diameter of the liquid outlet 21b needs to be controlled within a relatively reasonable range, so that the condensed liquid sprayed through the liquid spraying area 20a presents a water mist surface form, and the operation reliability of the spray assembly 20 can also be ensured.

[0074] The radius of the liquid outlet 21b is R, the flow of the condensed liquid is Q, and the flow rate of the condensed liquid sprayed through the liquid outlet 21b is v, Q = πR 2 × v. Generally, Q is controlled at about 0.27 L / min, and the flow rate v of the condensed liquid sprayed through the liquid outlet 21b needs to be controlled at about 11 m / s. By substituting the formula and rounding, it is obtained that the radius R of the liquid outlet 21b needs to be controlled at about 0.7 mm. That is, the diameter of the liquid outlet 21b is less than 1.4 mm, so that the condensed liquid can be sprayed in the form of a water mist surface.

[0075] In the embodiment of the present application, the diameter of the liquid outlet 21b ranges from 0.5 mm to 2 mm. For example, the diameter 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, and the like.

[0076] It should be noted that the diameter of the liquid outlet 21b is as shown in D1 of Figure 5 or Figure 9 .

[0077] Here, the diameter of the liquid outlet 21b does not exceed 2 mm, so that the condensed liquid sprayed through the liquid spraying area 20a is more likely to present a water mist surface form. At the same time, the diameter of the liquid outlet 21b is not less than 0.5 mm, so that the scale in the condensed liquid can flow through the liquid outlet 21b, which is beneficial to reduce the possibility of the liquid outlet 21b being blocked, thereby improving the possibility of the spray assembly 20.

[0078] In summary, the condenser of the embodiment of the present application controls the diameter of the liquid outlet 21b in the range of 0.5mm to 2mm, thereby facilitating the condensate to be sprayed out of the spraying area 20a in the form of a water mist surface, and also facilitating the scale in the condensate to flow through the liquid outlet 21b, which is conducive to reducing the possibility of the liquid outlet 21b being blocked, thereby improving the reliability of the spraying assembly 20. When the wet hot airflow with lint flows through the water mist surface, on the one hand, the surface area of the water mist surface is relatively large, i.e., the heat exchange area with the wet hot airflow is also relatively large, thereby being able to improve the heat exchange efficiency between the condensate and the wet hot airflow, and further improve the drying efficiency of the clothes treatment equipment; on the other hand, the lint in the wet hot airflow will be slowed down, wetted, and weighted, and no longer advance with the airflow, i.e., the water mist surface also plays a filtering role on the circulating airflow in the clothes treatment equipment, thereby being conducive to reducing the possibility of the 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.

[0079] In some embodiments, the diameter of the liquid outlet 21b ranges from 0.6mm to 0.8mm. For example, 0.6mm, 0.62mm, 0.64mm, 0.66mm, 0.68mm, 0.7mm, 0.72mm, 0.74mm, 0.76mm, 0.78mm, 0.8mm, and the like.

[0080] The diameter of the liquid outlet 21b in this range is more suitable when the flow rate of the condensate is 0.25L / min. Of course, if the flow rate of the condensate increases to a degree greater than 0.25L / min, the diameter of the liquid outlet 21b can be increased to a maximum of 2mm.

[0081] In some embodiments, referring to Figures 2 to 5 , or Figures 6 to 9 , the spraying assembly 20 comprises a liquid outlet section 21 and an impact structure 22, the liquid outlet section 21 extends along the axial direction of the air inlet 10c, the end wall of one end of the liquid outlet section 21 is a first structure wall 211, the impact structure 22 is arranged on the first structure wall 211 and cooperates with the first structure wall 211 to define a 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 through the first structure wall 211 to form a liquid outlet 21b, the condensate can flow through the liquid outlet channel 21a and be sprayed out of the liquid outlet 21b, and the condensate sprayed out of the liquid outlet 21b impacts on the impact structure 22 to form a water mist surface.

[0082] The liquid outlet channel 21a can also extend along the axial direction of the air inlet 10c, so that the flow resistance in the liquid outlet channel 21 is smaller, which is conducive to ensuring the flow rate of the condensate at the liquid outlet 21b.

[0083] The diameter of the liquid outlet channel 21a can be greater than that of the liquid outlet 21b. In this way, the flow resistance of the condensed liquid in the liquid outlet channel 21a is not too large, which is conducive to reducing the kinetic energy loss of the condensed liquid during flow, thereby ensuring the flow rate of the condensed liquid at the liquid outlet 21b.

[0084] Here, the condensed liquid is linearly sprayed along the axial direction of the liquid outlet 21b. At this time, the condensed liquid has a certain flow rate, and the linear condensed liquid impacts on the inner wall of the liquid spraying area 20a, and is then sprayed from the liquid spraying area 20a and can present a water mist surface.

[0085] In this embodiment, the liquid spraying area 20a is formed by the impact structure 22 and the liquid outlet section 21. The forming method of the liquid spraying area 20a is relatively simple, which is conducive to the production of the spraying assembly 20.

[0086] In some embodiments, the liquid outlet section 21 is a metal piece. 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 alloy), etc.

[0087] Alternatively, the inner lining of the liquid outlet section 21 is a metal piece.

[0088] In this embodiment, the liquid outlet section 21 can be formed by machining or other processes. The forming method is relatively simple. At the same time, since the surface of the metal piece is relatively smooth, the inner wall of the liquid outlet channel 21a is also relatively smooth, and the scale in the condensed liquid is difficult to remain in the liquid outlet channel 21a, thereby reducing the possibility of blockage of the liquid outlet channel 21a.

[0089] In other embodiments, the liquid outlet section 21 can also be a plastic piece, which can be formed by injection molding or other processes.

[0090] The specific structure of the impact structure 22 is not limited.

[0091] In some embodiments, referring 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 structure wall 211 are spaced apart, and the support portion 222 is connected to the impact portion 221 and the first structure wall 211, respectively. The support portion 222, the impact portion 221, and the first structure wall 211 jointly define the liquid spraying area 20a.

[0092] Here, the impact structure 22 mainly forms the water mist surface through the impact portion 221, and the support portion 222 mainly serves to connect the first structure wall 211 and the impact portion 221.

[0093] At least part of the condensed liquid sprayed out of the liquid outlet 21b will sweep across the surface of the impact portion 221, and the part of the condensed liquid will flow in multiple directions on the surface of the impact portion 221, thus forming a planar shape and being able to be sprayed out of the periphery of the impact portion 221, and thus forming a water mist plane that crosses the condensation channel 10a.

[0094] In this embodiment, the impact structure 22 can be formed into a water mist plane by using a relatively simple structure, and the impact structure 22 is easy to form.

[0095] In some embodiments, referring to Figure 2 and Figure 5 , the side of the impact portion 221 facing the first structure wall 211 is a forming wall 22a, which is used to form at least part of the water mist plane, and the support portion has a second structure wall 22b connected to the first structure wall 211 and the forming wall 22a, respectively, and the first structure wall 211, the forming wall 22a, and the second structure wall 22b together define the liquid spraying area 20a; wherein the second structure wall 22b is an arc surface, and the projection of the second structure wall 22b on the first structure wall 211 extends along the circumferential direction of the liquid outlet 21b.

[0096] It should be noted that the second structure wall 22b can be an arc surface that is arc-shaped in the circumferential direction of the liquid outlet 21b, or an arc surface that is arc-shaped in the axial direction of the liquid outlet 21b, or an arc surface that is arc-shaped in both the circumferential direction and the axial direction of the liquid outlet 21b. The present application does not limit this.

[0097] Here, the condensed liquid sprayed out of the liquid outlet 21b impacts on the second structure wall 22b, and since the second structure wall 22b is an arc surface, it can guide at least part of the condensed liquid to flow to the forming wall 22a, and after the part of the condensed liquid flows through the forming wall 22a, it is formed into a planar shape, thus being sprayed out of the liquid spraying area 20a and appearing in the form of a water mist plane.

[0098] Of course, the condensed liquid can also not be guided by the second structure wall 22b, and thus directly impact the forming wall 22a.

[0099] The forming wall 22a can be a plane, and can be perpendicular to the axis of the liquid outlet 21b.

[0100] In this embodiment, the second structure wall 22b can guide the flow of the condensed liquid, which is conducive to reducing the rebound phenomenon that occurs when the condensed liquid sprayed out of the liquid outlet 21b impacts on the inner wall of the liquid spraying area 20a, and the condensed liquid can be sprayed out in the form of a water mist plane more, thus being conducive to increasing the area of the water mist plane, and thus improving the condensation effect of the condenser 1. Moreover, the second structure wall 22b can limit the spray angle of the water mist formed by the water flow, increase the spray pressure, and enhance the spray distance, thus enhancing the effect of removing the lint.

[0101] It can be understood that in the above embodiment, the liquid spraying area 20a can spray the condensed liquid along the circumferential part of the liquid outlet 21b, that is, the liquid spraying area 20a is located at the outer edge of the water mist surface.

[0102] In other embodiments, referring to Figure 6 , Figures 9 to 11 , the side of the impact portion 221 facing the first structure wall 211 is a shaped wall 22a, which is used to form the water mist surface, and the support portion 222 has two third structure walls 222a, any one of which is connected with the first structure wall 211 and the impact portion 221 at the two ends along the axial direction of the liquid outlet 21b, and the two third structure walls 222a are connected with each other at the two ends along the radial direction of the liquid outlet 21b; wherein the projection of the third structure wall 222a on the first structure wall 211 along the axial direction of the liquid outlet 21b extends along the radial direction of the liquid outlet 21b.

[0103] The shaped wall 22a can be a curved surface and can be perpendicular to the axis of the liquid outlet 21b.

[0104] The size of the support portion 222 along the circumferential direction of the liquid outlet 21b is relatively small, and the liquid spraying area 20a can spray the condensed liquid along any angle (i.e. 360° angle) along the circumferential direction of the liquid outlet 21b, and the liquid spraying area 20a is located at the central position of the water mist surface.

[0105] In this embodiment, under the condition that the flow rate of the condensed liquid is constant, since the liquid spraying area 20a can spray the condensed liquid along the circumferential direction, the area of the water mist surface formed is larger, which is beneficial to improve the condensation efficiency of the condenser 1.

[0106] In some embodiments, referring to Figure 10 and Figure 11 , the number of support portions 222 is multiple, and each support portion 222 is arranged at intervals along the circumferential direction of the liquid outlet 21b.

[0107] It should be noted that the intervals of the support portions 222 along the circumferential direction of the liquid outlet 21b can be equal or unequal, which is not limited in the present application.

[0108] Exemplarily, Figure 10 and Figure 11 , the number of support portions 222 is three.

[0109] By arranging multiple support portions 222 to support the impact portion 221, when the impact portion 221 is impacted by the condensed liquid, the multiple support portions 222 jointly support the impact portion 221, and the impact portion 221 is more stable and reliable.

[0110] In some embodiments, referring to Figure 10 andFigure 11 , the third structural wall 222a is an arc-shaped surface.

[0111] Here, the condensate is sprayed out through the spray area 20a along the radial direction of the liquid outlet 21b. When the condensate flows through the support portion 222, it flows through the surface of the third structural wall 222a. The third structural wall 222a is an arc-shaped surface, which is beneficial to reducing the flow resistance of the condensate. The flow rate of the condensate when it is sprayed through the spray area 20a is greater, and the area of ​​the formed water mist surface is larger, which is beneficial to improving the condensation effect of the condenser 1.

[0112] In some embodiments, when projected onto a plane perpendicular to the axial direction of the liquid outlet 21 b , the projection of the forming wall 22 a is a circle, an ellipse, a polygon, or a shape surrounded by multiple arcs.

[0113] The polygon may be, for example, a triangle, a quadrilateral, a pentagon, or the like.

[0114] For example, Figure 10 and Figure 11 In the illustrated embodiment, the projection of the forming wall 22a is a shape surrounded by three arcs.

[0115] In this embodiment, the shape of the forming wall 22a is relatively regular, which is convenient for production.

[0116] For some examples, see Figure 5 or Figure 9 In the axial direction of the liquid outlet 21b, the distance between the liquid outlet 21b and the molding wall 22a is not less than 3mm, for example, 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 5mm, etc.

[0117] Here, the distance between the forming wall 22a and the liquid outlet 21b is more appropriate. The condensed liquid has a certain impact height before reaching the forming wall 22a after being sprayed out through the liquid outlet 21b, which is beneficial to reduce the impact of the condensed liquid rebounding from the forming wall 22a on the condensed liquid sprayed out through the liquid outlet 21b, thereby facilitating the formation of the water mist surface.
