[0065] The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0066] The application provides a laundry treating apparatus, please refer to Figure 1 The laundry treating apparatus includes a drum assembly 2 and the condenser 1 of any one of the embodiments of the application.

[0067] The laundry treating apparatus can be a clothes dryer, a washer-dryer, etc., which is not limited herein.

[0068] The drum assembly 2 has a laundry treating cavity inside, in which the laundry completes washing, dehydration or drying, etc.

[0069] 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 treating cavity, and the inner drum is rotatably supported in the outer drum, and the condenser 1 is arranged on the outer drum.

[0070] 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 filled with condensing liquid, the humid hot air flow in the clothes 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, which is discharged from the condenser 1 together with the condensing liquid. The humid hot air after condensation becomes relatively dry cold air.

[0071] The specific type of the condensing liquid is not limited. Exemplarily, the condensing liquid can be water.

[0072] The downstream of the condenser 1 is provided with a heating channel 3, and the space of the heating channel 3 and the internal space of the condenser 1 together constitute a drying channel of the clothes treatment device. The heating channel 3 is provided with a fan and a heater. 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 clothes treatment cavity for drying clothes. In this way, the air flow circulates between the clothes treatment cavity and the drying channel, realizing continuous drying of the clothes, and the fan provides power for the air flow circulation.

[0073] It can be understood that in the process of circulating flow, the air flow may carry the lint of the clothes 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 in the drying channel. Even if it is cleaned in the drying channel, the cleaning liquid is difficult to uniformly cover the filter screen, so there is still a problem that part of the lint remains on the filter screen and cannot be cleaned. In the long run, it will also block the drying channel, cause the air flow to decrease, and affect the drying efficiency.

[0074] Therefore, the embodiment of the present application also provides a condenser, please refer to Figure 2 or Figure 6 The condenser 1 comprises a shell assembly 10 and a spraying assembly 20.

[0075] The shell assembly 10 is provided with a condensing channel 10a, and the condensing channel 10a has an air outlet 10b and an air inlet 10e. Specifically, the condensing channel 10a is communicated with the inside of the heating channel 3 through the air outlet 10b, and is 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.

[0076] The inner wall of the condensing channel 10a opposite to the air inlet 10e is a wind blocking wall 10d, and the air flow in the clothes treatment cavity enters the condensing channel 10a through the air inlet 10e and changes the flow direction under the action of the wind blocking wall 10d.

[0077] The condensing passage 10a is a place where the moist hot air and the condensed liquid exchange heat. The condensing passage 10a is in communication with the clothes treatment cavity, and the moist hot air in the clothes treatment cavity enters the condensing passage 10a and dehumidifies in the condensing passage 10a.

[0078] The spraying assembly 20 is used to guide the condensed liquid into the condensing passage 10a. During use of the clothes treatment device, the condensed liquid is supplied to the condenser 1 through the liquid supply pipeline. Specifically, the liquid supply pipeline is in communication with the spraying assembly 20, and the condensed liquid flows out from the liquid supply pipeline, flows through the spraying assembly 20, and enters the condensing passage 10a.

[0079] The spraying assembly 20 is provided with a water outlet unit, and the water outlet unit is located in the condensing passage 10a. The condensed liquid can be sprayed out through the water outlet unit and form a water mist surface that crosses the condensing passage 10a.

[0080] It should be noted that the condensed liquid is sprayed out from the water outlet unit and presents a large number of small particles, and these small particles enclose a certain volume shape. The surface of the volume shape is called the water mist surface.

[0081] When the moist hot air with the lint flows through the water mist surface, the moist hot air exchanges heat with the condensed liquid that presents the water mist surface. In the related art, the condensed liquid flows in a single column or multiple columns in the condenser, and the heat exchange area between the condensed liquid and the moist hot air is relatively small, and the heat exchange efficiency is low, which affects the drying efficiency of the clothes. However, the spraying assembly 20 of the present application can spray the condensed liquid and present the water mist surface, and the surface area of the water mist surface is relatively large, that is, the heat exchange area with the moist hot air is also relatively large, thereby improving the heat exchange efficiency between the condensed liquid and the moist hot air, and further improving the drying efficiency of the clothes treatment device.

[0082] In addition, the lint in the moist hot air 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, 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 device.

[0083] 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 arranged 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 device are relatively few, which is beneficial to improving the production cost and production efficiency of the clothes treatment device.

[0084] The water outlet unit is arranged at intervals from the wind barrier 10d. In this way, the water mist surface sprayed out through the water outlet unit is also arranged at intervals from the wind barrier 10d, and the airflow can pass through the water mist surface.

[0085] 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 deflector 10d, but there is a certain spacing between the water outlet unit of the spraying assembly 20 and the wind deflector 10d; for another example, the spraying assembly 20 can not be directly connected to the wind deflector 10d, and thus there is a certain spacing between the water outlet unit and the wind deflector 10d.

[0086] It should be noted that the specific direction of spacing is not limited. Exemplarily, the water outlet unit and the wind deflector 10d are spaced apart in a direction perpendicular to the wind deflector 10d.

[0087] The specific position of the water outlet unit in the condensing channel 10a is not limited. Exemplarily, in the height direction of the condenser 1, the water outlet unit is lower than the air outlet 10b.

[0088] It should be noted that after the condenser 1 is used in the clothes treatment apparatus, the height direction of the condenser 1 is the same direction as the height direction of the clothes treatment apparatus. For details, please refer to the schematic in Figure 2 、 Figure 3 、 Figure 6 or Figure 7 .

[0089] 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 condensate sprayed out by the water outlet unit falls under the action of gravity, so 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 more used to heat the airflow, thus it is beneficial to improve the temperature of the airflow, and the airflow with higher temperature has better drying effect on the clothes.

[0090] In summary, the condenser of the embodiment of the present application, the spraying assembly 20 can spray the condensate in the form of a water mist surface and act on the condensing channel 10a. During the process of the wet and hot airflow flowing through the cross section of the flow channel, the lint in the wet and hot airflow will be slowed down, wetted, and weighted, and will no longer advance with the airflow. Thus, it is beneficial to reduce the possibility of lint remaining in the drying channel, thereby ensuring the air volume in the drying channel and improving the drying efficiency of the clothes treatment apparatus. At the same time, since the water mist surface also has a filtering effect, a filter element such as a filter screen can not be used to filter the lint in the drying channel, and components for cleaning the filter element are also 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.

[0091] In addition, the surface area of the water mist surface is relatively large, that is, the heat exchange area with the wet and hot airflow is also relatively large, thereby improving the heat exchange efficiency of the condensate and the wet and hot airflow, and further improving the drying efficiency of the clothes treatment apparatus.

[0092] In some embodiments, the extension surface is the surface on which the water mist surface is located, the extension surface intercepts the condensation passage 10a to form a flow passage cross section, and the area ratio of the water mist surface on the flow passage cross section is not less than 80%. For example, 80%, 82%, 84%, 86%, 88%, 90%, 92%, 94%, 96%, 98%, 100%, and the like.

[0093] The extension surface and the water mist surface are on the same surface, and the extension surface can be understood as the surface formed by infinitely enlarging the water mist surface.

[0094] It can be understood that the greater the area ratio of the water mist surface on the flow passage cross section, the better the covering effect of the water mist surface on the flow passage cross section. When the value of the area ratio reaches 100%, the airflow will pass through the water mist surface as a whole when flowing through the flow passage cross section. In this way, the gas can be effectively dehumidified and filtered as a whole.

[0095] In the present embodiment, the area ratio of the water mist surface on the flow passage cross section is controlled to be not less than 80%, and the water mist surface with the area ratio can achieve good dehumidification and filtering effects on the airflow flowing through the flow passage cross section. It should be noted that the specific structure of the water outlet unit is not limited.

[0096] In some embodiments, the water outlet unit includes a plurality of liquid outlets 21b, each liquid outlet 21b sprays along its axial direction and forms a linear fluid in the radial direction of the condensation passage 10a, and the linear fluids collectively constitute the water mist surface.

[0097] The "linear fluid" refers to the linear shape of the condensed liquid sprayed through the liquid outlet 21b.

[0098] Each linear fluid can be arranged in parallel, or at least part of the linear fluids are arranged at an angle.

[0099] The plurality of linear fluids collectively constitute the water mist surface. For example, when at least part of the linear fluids are arranged at an angle, the linear fluids can be distributed in a cross manner to form a grid-shaped water mist surface. Taking one of the liquid outlets 21b as an example, the extension direction of the linear fluid sprayed by the liquid outlet 21b is parallel to the axial direction of the liquid outlet 21b.

[0100] It should be noted that the specific arrangement of each liquid outlet 21b is not limited.

[0101] For example, taking one point as the center of a circle, each liquid outlet 21b is distributed around the center of the circle in a counterclockwise or clockwise direction, and the axial direction of at least part of the liquid outlets 21b passes through the center of the circle.

[0102] For example, all the liquid outlets 21b include a first part and a second part, the liquid outlets 21b in the first part are arranged at intervals along a first direction, the liquid outlets 21b in the second part are arranged at intervals along a second direction, and the first direction intersects the second direction. The liquid outlets 21b in the first part all spray linear fluid in the second direction, and the liquid outlets 21b in the second part all spray linear fluid in the first direction. In this way, the water mist surface can also be formed.

[0103] In other embodiments, referring to Figure 4 and Figure 5 , or Figure 8 and Figure 9 , the water outlet unit includes the liquid outlets 21b and the liquid spraying area 20a in communication with the liquid outlets 21b. The inner wall of the liquid spraying area 20a includes the forming wall 22a, which is arranged at intervals with the liquid outlets 21b along the axial direction of the liquid outlets 21b. The condensed liquid can be sprayed out of the liquid outlets 21b and enter the liquid spraying area 20a, and then exit the liquid spraying area 20a through the circumferential side of the forming wall 22a to form a water mist surface.

[0104] Here, the condensed liquid is sprayed linearly along the axial direction of the liquid outlets 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. Part of the condensed liquid flows through the forming wall 22a and is sprayed out of the liquid spraying area 20a through the outer edge of the forming wall 22a. In this way, the condensed liquid can be in the form of a water mist surface.

[0105] It can be understood that in this embodiment, the water mist surface extends approximately along the extension direction of the outer edge of the forming wall 22a. By arranging the liquid spraying area 20a, the spray assembly 20 can form a water mist surface with only one liquid outlet 21b. In this way, the structure of the spray assembly 20 is simpler. At the same time, it is also convenient for the spray assembly 20 to occupy less space in the condensing channel 10a, thereby facilitating the reduction of the air resistance in the condensing channel 10a to ensure the flow rate of the airflow and the drying efficiency of the clothes.

[0106] It can be understood that in order to ensure that the condensed liquid sprayed out of the liquid spraying area 20a is in the form of a water mist surface, it is necessary to ensure that the condensed liquid sprayed out of the liquid outlets 21b has a certain flow rate.

[0107] 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.

[0108] 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.

[0109] In some embodiments, referring to Figure 5 or Figure 9 , 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.

[0110] It should be noted that the diameter of the liquid outlet 21b is as shown by D1 in Figure 5 or Figure 9 .

[0111] 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.

[0112] In some embodiments, referring to Figure 5 or Figure 9The diameter of the liquid outlet 21b is in the range of 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, etc.

[0113] The diameter of the liquid outlet 21b in this range is more suitable when the flow rate of the condensed liquid is 0.25L / min. Of course, if the flow rate of the condensed liquid is increased to more than 0.25L / min, the diameter of the liquid outlet 21b can be increased to a maximum of 2mm.

[0114] When the flow rate of the condensed liquid is small, the water mist particles that form the water mist surface are large, the particle gap is large, and fine lint can still pass through, resulting in poor filtering effect. When the flow rate of the condensed liquid is large, the water mist particles that form the water mist surface are small, the particle gap is small, and fine lint is easily intercepted, but the amount of condensed liquid used is relatively large.

[0115] In actual use, in the initial stage of drying, small flow control is performed first to intercept large lint. In the later stage of drying, when fine lint begins to increase, large flow control is performed to intercept fine lint. In the last stage near the end, when the amount of lint is very small, small flow control is performed again. In this way, the amount of condensed liquid used can be saved as much as possible, while ensuring good filtering effect.

[0116] It should be noted that the number of liquid spraying areas 20a is not limited.

[0117] In some embodiments, referring to Figure 2 or Figure 6 only one liquid spraying area 20a can be provided, which is beneficial to reducing the size of the spraying assembly 20 as much as possible and reducing the space occupied by the spraying assembly 20 in the condensed channel 10a.

[0118] In other embodiments, the number of liquid spraying areas 20a is multiple, and each liquid spraying area 20a can spray to form a water mist sub-surface, and the water mist sub-surfaces together form the water mist surface.

[0119] In this way, under the condition that the total area of the water mist surface is constant, the area of the water mist sub-surface formed by each liquid spraying area 20a can be designed to be relatively small, which can reduce the flow rate requirement of the condensed liquid flowing out of the liquid outlet 21b, and facilitate the flow control design of the condensed liquid and the size design of the liquid outlet 21b.

[0120] It should be noted that when the number of liquid spraying areas 20a is multiple, the specific positions of the liquid spraying areas 20a are not limited.

[0121] Exemplarily, projections of any two liquid spraying areas 20a exist non-overlapping areas in a plane perpendicular to the height direction of the condenser 1.

[0122] In this way, the water mist sub-surfaces sprayed by the liquid spraying areas 20a also exist non-overlapping areas, so that the projection area of the water mist surface formed by the water mist sub-surfaces is larger, thereby better covering the flow passage cross section, which is conducive to improving the dehumidification effect and filtering effect of the water mist surface on the hot and humid airflow.

[0123] 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 provided with a shaped wall 22a, an 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 liquid spraying area 20a, and the liquid outlet section 21 is provided with a liquid outlet channel 21a, one end of the liquid outlet channel 21a penetrates the first structure wall 211 to form a liquid outlet 21b.

[0124] Exemplarily, the liquid outlet section 21 extends along the axial direction of the air inlet passage 10c, and the liquid outlet channel 21a also extends along the axial direction of the air inlet passage 10c.

[0125] The condensate can flow through the liquid outlet channel 21a and be sprayed out through the liquid outlet 21b, and the condensate sprayed out through the liquid outlet 21b impacts on the impact structure 22 to form a water mist surface.

[0126] The diameter of the liquid outlet channel 21a can be greater than that of the liquid outlet 21b, so that the flow resistance of the condensate in the liquid outlet channel 21a is not too large, which is conducive to reducing the kinetic energy loss of the condensate during flow, thereby ensuring the flow rate of the condensate at the liquid outlet 21b.

[0127] The condensate sprayed out through the liquid outlet 21b impacts on the impact structure 22, thereby being sprayed out from the peripheral side of the liquid spraying area 20a and assuming the form of a water mist surface.

[0128] In this embodiment, the liquid spraying area 20a is shaped by the impact structure 22 and the liquid outlet section 21, and the shaping mode of the liquid spraying area 20a is relatively simple, which is conducive to the production of the spraying assembly 20.

[0129] 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 may, for example, be stainless steel, copper, iron, aluminum, and various alloy materials (such as aluminum alloy), etc.

[0130] Alternatively, the inner lining of the liquid outlet section 21 is a metal piece.

[0131] In the embodiment, the liquid outlet section 21 can be formed by machining or other processes, and the forming method is relatively simple. Meanwhile, because the surface of the metal piece is relatively smooth, the inner wall of the liquid outlet passage 21a is also relatively smooth, and scale in the condensed liquid is difficult to remain in the liquid outlet passage 21a, thereby facilitating reduction of the possibility of blockage of the liquid outlet passage 21a.

[0132] In other embodiments, the liquid outlet section 21 can also be a plastic piece, which can be formed by injection molding or other processes.

[0133] The specific structure of the impact structure 22 is not limited.

[0134] In some embodiments, referring to Figure 10 or Figure 12 , the impact structure 22 includes a support portion 222 and an impact portion 221, and the impact portion 221 and the first structure wall 211 are spaced apart along the axial direction of the liquid outlet 21b. The side of the impact portion 221 facing the first structure wall 211 is a shaped wall 22a, and the support portion 222 is connected to the impact portion 221 and the first structure wall 211, respectively. The support portion 222, the shaped wall 22a, and the first structure wall 211 jointly define a liquid ejection area 20a.

[0135] Here, the impact structure 22 is mainly formed by the impact portion 221 to form a water mist surface, and the support portion 222 mainly serves to connect the first structure wall 211 and the impact portion 221.

[0136] At least a portion of the condensed liquid ejected through the liquid outlet 21b will pass over the surface of the shaped wall 22a. This portion of the condensed liquid flows in multiple directions on the surface of the shaped wall 22a, thereby forming a surface shape and being able to be ejected through the peripheral side of the shaped wall 22a. In this way, a water mist surface that intersects the condensed passage 10a is formed.

[0137] In the embodiment, the impact structure 22 can be formed to form a water mist surface by using a relatively simple structure, and the impact structure 22 is easy to form.

[0138] In some embodiments, referring to Figure 2 and Figure 5 , the support portion 222 has a second structure wall 22b, and the second structure wall 22b is connected to the first structure wall 211 and the shaped wall 22a, respectively. The first structure wall 211, the shaped wall 22a, and the second structure wall 22b jointly define a liquid ejection area 20a. The second structure wall 22b is an arc surface, and a projection of the second structure wall 22b on the first structure wall 211 extends along the circumferential direction of the liquid outlet 21b.

[0139] It should be noted that the second structure wall 22b can be an arc surface in the circumferential direction of the liquid outlet 21b; can also be an arc surface in the axial direction of the liquid outlet 21b; or can be an arc surface in both the circumferential direction and the axial direction of the liquid outlet 21b. The present application does not limit this.

[0140] Here, the forming wall 22a can be a plane and can be perpendicular to the axis of the liquid outlet 21b.

[0141] Here, the condensed liquid sprayed through the liquid outlet 21b impacts on the second structure wall 22b, and since the second structure wall 22b is an arc surface, at least part of the condensed liquid can be guided to flow to the forming wall 22a. After flowing through the forming wall 22a, this part of the condensed liquid is shaped into a plane and is sprayed through the liquid spraying area 20a and appears in the form of a water mist surface.

[0142] Of course, the condensed liquid can also not be guided through the second structure wall 22b, but directly impact the forming wall 22a.

[0143] In the present embodiment, the second structure wall 22b can guide the flow of condensed liquid, which is conducive to reducing the rebound phenomenon that occurs when the condensed liquid sprayed through the liquid outlet 21b impacts on the inner wall of the liquid spraying area 20a. The condensed liquid can be sprayed in the form of a water mist surface more, which is conducive to increasing the area of the water mist surface and thus improving the condensing effect of the condenser 1. The second structure wall 22b can also limit the spray angle of the water mist formed by the water flow, increase the spray pressure, and enhance the spray distance, thereby enhancing the effect of removing the lint.

[0144] It can be understood that in the above embodiment, the portion of the liquid spraying area 20a along the circumferential direction of the liquid outlet 21b can spray condensed liquid, i.e., the liquid spraying area 20a is located at the outer edge of the water mist surface.

[0145] In other embodiments, please refer to Figure 6 、 Figures 9 to 11 The support part 222 has two third structure walls 222a, any one of which is connected with the first structure wall 211 and the impact part 221 at both ends along the axial direction of the liquid outlet 21b, and the two third structure walls 222a are connected with each other at both ends along the radial direction of the liquid outlet 21b; wherein the projection of the third structure wall 222a along the axial direction of the liquid outlet 21b extends along the radial direction of the liquid outlet 21b.

[0146] Here, the forming wall 22a can be an arc surface and can be perpendicular to the axis of the liquid outlet 21b.

[0147] The support portion 222 has a relatively small size in the circumferential direction of the liquid outlet 21b. The liquid spray area 20a can spray the condensed liquid in any angle (i.e. 360°) in the circumferential direction of the liquid outlet 21b. The liquid spray area 20a is located at the center of the water mist surface.

[0148] In the embodiment, the liquid spray area 20a can spray the condensed liquid in the circumferential direction of the liquid outlet 21b. Thus, the water mist surface formed has a larger area, which is beneficial to improve the condensing efficiency of the condenser 1.

[0149] In some embodiments, referring to Figure 10 and Figure 11 , the support portion 222 has a plurality of support portions 222 which are arranged at intervals in the circumferential direction of the liquid outlet 21b.

[0150] It should be noted that the support portion 222 can be arranged at equal intervals or at unequal intervals in the circumferential direction of the liquid outlet 21b, which is not limited in the present application.

[0151] For example, Figure 10 and Figure 11 , the support portion 222 has three support portions 222 in the embodiment.

[0152] The impact portion 221 is supported by the plurality of support portions 222. When the impact portion 221 is impacted by the condensed liquid, the plurality of support portions 222 collectively support the impact portion 221, so that the impact portion 221 is more stable and reliable.

[0153] In some embodiments, referring to Figure 10 and Figure 11 , the third structure wall 222a has an arc surface.

[0154] Here, the condensed liquid is sprayed through the liquid spray area 20a in the radial direction of the liquid outlet 21b. When the condensed liquid flows through the support portion 222, it flows from the surface of the third structure wall 222a. The third structure wall 222a has an arc surface, which is beneficial to reduce the flow resistance of the condensed liquid. The flow rate of the condensed liquid sprayed through the liquid spray area 20a is larger, and the water mist surface formed has a larger area, which is beneficial to improve the condensing effect of the condenser 1.

[0155] In some embodiments, the projection of the forming wall 22a on a plane perpendicular to the axis of the liquid outlet 21b is a circular shape, an elliptical shape, a polygonal shape, or a shape surrounded by a plurality of arc lines.

[0156] The polygonal shape can be a triangular shape, a quadrilateral shape, a pentagonal shape, etc.

[0157] For example, Figure 10 and Figure 11 , the projection of the forming wall 22a has a shape surrounded by three arc lines in the embodiment.

[0158] In this embodiment, the shape of the forming wall 22a is relatively regular, which is convenient for production.

[0159] In some embodiments, referring to Figure 5 or Figure 9 , the distance between the liquid outlet 21b and the forming wall 22a along the axial direction of the liquid outlet 21b is not less than 3 mm. For example, 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm, 5 mm, and the like.

[0160] Here, the distance between the forming wall 22a and the liquid outlet 21b is more suitable. After the condensed liquid is sprayed out of the liquid outlet 21b, it has a certain impact height before reaching the forming wall 22a, which is conducive to reducing the influence of the rebounded condensed liquid of the forming wall 22a on the condensed liquid sprayed out of the liquid outlet 21b, thereby facilitating the forming of the water mist surface.

[0161] In some embodiments, referring to Figures 2 to 5 or Figures 6 to 9 , the condensation channel 10a comprises a first sub-channel 10a1 and an air inlet channel 10c arranged at an angle, the air inlet channel 10c has an air inlet 10e, and the first sub-channel 10a1 is located downstream of the air inlet channel 10c. In the cross section on the plane perpendicular to the axial direction of the air inlet channel 10c, the cross-sectional area of the air inlet channel 10c is smaller than that of the first sub-channel 10a1.

[0162] Here, the first sub-channel 10a1 communicates with the clothes treatment cavity through the air inlet channel 10c.

[0163] Exemplarily, referring to Figure 4 or Figure 8 , the extension direction of the first sub-channel 10a1 is perpendicular to the axial direction of the air inlet channel 10c, and part of the structure of the spraying assembly 20 is arranged in the first sub-channel 10a1.

[0164] The first sub-channel 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.

[0165] Exemplarily, the first sub-channel 10a1 extends along the height direction of the condenser 1, and the air inlet channel 10c communicates with 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 condensed liquid remaining in the first sub-channel 10a1 or the air inlet channel 10c falls under the action of gravity, which is conducive to further reducing the possibility of the condensed liquid entering the heating channel 3.

[0166] 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 setting the air inlet channel 10c and the first sub-channel 10a1 at an angle, a bending structure is formed at the connection between the air inlet channel 10c and the first sub-channel 10a1, even if the 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 beneficial to reduce the probability of water mist particles entering the heating channel 3.

[0167] It should be noted that the structure for stopping water mist particles here is the air baffle 10d described above.

[0168] The liquid outlet section 21 is arranged along the axial direction of the air inlet channel 10c. In this way, the liquid outlet channel 21a also extends along the axial direction of the air inlet channel 10c, and the shaped wall 22a is substantially perpendicular to the axial direction of the air inlet channel 10c. Since the surface where the water mist surface is located is substantially parallel to the surface where the shaped wall 22a is located, 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 air flow flows through the water mist surface along the axial direction of the air inlet channel 10c, and therefore, the water mist surface is substantially perpendicular to the flow direction of the air flow. 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, thereby, it is beneficial to improve the dehumidification effect and filtration effect of the water mist surface on the wet hot air flow.

[0169] In some embodiments, referring to Figure 4 or Figure 8 , the condensation channel 10a further comprises a second sub-channel 10a2, the second sub-channel 10a2 is directly communicated with the first sub-channel 10a1, and the extension direction of the second sub-channel 10a2 intersects with the extension direction of the first sub-channel 10a1.

[0170] That is, the connection between the first sub-channel 10a1 and the second sub-channel 10a2 forms a corner, through which the possibility of the condensate entering the second sub-channel 10a2 can be reduced, and the air outlet 10b is communicated with the second sub-channel 10a2, which is beneficial to reduce the possibility of the condensate entering the heating channel 3.

[0171] In some embodiments, referring to Figure 5 or Figure 9 , the shaped wall 22a is located in the air inlet channel 10c.

[0172] It can be understood that the water mist surface extends along the extension direction of the outer edge of the shaped wall 22a. In this embodiment, by arranging the shaped wall 22a in the air inlet channel 10c, the water mist surface formed thereby can also be located in the air inlet channel 10c.

[0173] In some embodiments, referring to Figures 2 to 5 , or Figures 6 to 9 , the housing assembly 10 comprises 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 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 formed by 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. The shaped wall 22a is located between the first wall body 11a and the second wall body 12a.

[0174] Here, the area between the first wall body 11a and the second wall body 12a is the air inlet channel 10c.

[0175] 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 may pass through the gap, and the airflow passing through the gap will not be affected by the water mist surface.

[0176] In this embodiment, when the airflow flows through the gap between the outer edge of the water mist surface and the inner wall of the air inlet channel 10c, it will impact on the partition wall 12, and the partition wall 12 will produce a certain stopping effect on this part of the airflow, reducing the flow rate of this part of the airflow. In this way, it is beneficial to reduce the flow of airflow through the gap, thereby facilitating the increase of the flow of airflow through the water mist surface. That is, it is beneficial to improve the overall dehumidification and filtration effect of the airflow.

[0177] In some embodiments, the water mist surface is arranged to intersect the axial direction of the air inlet channel 10c. Or, the plane where the shaped wall 22a is located intersects the axial direction of the air inlet channel 10c. In this way, during the process of the airflow flowing into the condenser 1 through the air inlet channel 10c, the humid hot airflow is facilitated to pass through the water mist surface, thereby achieving the dehumidification and filtration effect.

[0178] In some embodiments, the water mist surface is perpendicular to the axial direction of the air inlet channel 10c. Or, the plane where the shaped wall 22a is located is perpendicular to the axial direction of the air inlet channel 10c. In this way, 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 equal to the area of the water mist surface itself, thereby facilitating the full use of the water mist surface and making the water mist surface have better coverage effect on the air inlet channel 10c.

[0179] In some embodiments, 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 not less than 80% of the projection area of the air inlet channel 10c. For example, 80%, 82%, 84%, 86%, 88%, 90%, 92%, 94%, 96%, 98%, 100%, etc.

[0180] Here, if the proportion of the projection area of the water mist surface on the projection area of the air inlet channel 10c is less than 100%, it indicates that the water mist surface does not completely cover the air inlet channel 10c.

[0181] It can be understood that the greater the proportion of the projection area of the water mist surface on the projection area of the air inlet channel 10c, the better the covering effect of the water mist surface on the air inlet channel 10c. When the value of the proportion reaches 100%, the airflow will pass through the water mist surface as a whole when flowing through the air inlet channel 10c. In this way, the gas can be effectively dehumidified and effectively filtered as a whole.

[0182] In the embodiment, the proportion of the projection area of the water mist surface on the projection area of the air inlet channel 10c is controlled to be not less than 80%, and the dehumidification effect and filtering effect of the water mist surface on the airflow can basically meet the requirements, thereby being beneficial to guarantee the drying efficiency of the clothes.

[0183] In some embodiments, referring to Figure 2 and Figure 3 , or Figure 6 and Figure 7 , the projection of the liquid spraying area 20a is located within the range of the air inlet channel 10c in the plane perpendicular to the axial direction of the air inlet channel 10c.

[0184] Exemplarily, the liquid spraying area 20a can be arranged in the air inlet channel 10c.

[0185] It can be understood that the airflow in the clothes treatment cavity flows into the condensation channel 10a through the air inlet channel 10c, and flows along the axial direction of the air inlet channel 10c. In the embodiment, the water mist surface formed can better cover the air inlet channel 10c, that is, better cover the flow passage cross section of the drying channel. When the airflow flows through the position where the water mist surface is located in the drying channel, most of the airflow can pass through the area covered by the water mist surface. Therefore, the dehumidification effect of the airflow is better, and the airflow is basically subjected to the filtering effect of the water mist surface, thereby being beneficial to reduce the probability of residual lint in the drying channel.

[0186] In some embodiments, referring to Figure 2 and Figure 3 , the projection of the liquid spraying area 20a is located at the top of the air inlet channel 10c.

[0187] More specifically, the liquid spraying area 20a is located at the top of the air inlet channel 10c.

[0188] It should be noted that the surface where the air inlet 10e is located extends along the height direction of the condenser 1, and the "top of the air inlet channel 10c" is generally close to the position of the top wall of the air inlet channel 10c.

[0189] 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 has a larger extension 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 small, 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.

[0190] In some other embodiments, as shown in Figure 6 and Figure 7 , the projection of the liquid spraying area 20a is located in the middle region of the air inlet channel 10c.

[0191] More specifically, the liquid spraying area 20a is located in the middle region of the air inlet channel 10c.

[0192] It should be noted that the surface where the air inlet 10e is located extends substantially along the height direction of the condenser 1, and the “middle region of the air inlet channel 10c” is substantially a position close to the center of the air inlet channel 10c.

[0193] As described in the above embodiments, when the liquid spraying area 20a is located at the center position of the water mist surface, the liquid spraying area 20a is arranged in the middle region of the air inlet channel 10c. In this way, the water mist surface is more suitable for the air inlet channel 10c, and the covering effect of the water mist surface on the air inlet channel 10c is better, 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.

[0194] In some embodiments, as shown in Figure 2 and Figure 3 , or Figure 6 and Figure 7 , the side wall of the air inlet channel 10c comprises 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 a first connecting line, and the connecting line between the two ends of the second arc-shaped wall 10c3 is a second connecting line.

[0195] The first arc-shaped wall 10c1 and the two linear extension walls 10c2 can be connected by a circular arc, and the second arc-shaped wall 10c3 and the two linear extension walls 10c2 can also be connected by a circular arc.

[0196] That is, the shape of the air inlet channel 10c is approximately pear-shaped.

[0197] The first connecting line is Figure 3 or Figure 7 the line L1, and the second connecting line is Figure 3 or Figure 7 the line L2.

[0198] In some embodiments, referring to Figure 3 , the liquid spraying area 20a is arranged in a first area formed by the first arc-shaped wall 10c1 and the first connecting line.

[0199] As Figures 2 to 5 , Figure 12 , in the embodiment in which the liquid spraying area 20a is located at the outer edge of the water mist surface, the condensed liquid is sprayed from the liquid spraying area 20a at an angle away from the first arc-shaped wall 10c1 along the median line of the first connecting line or the second connecting line, and the size of the water mist surface in the direction of the first connecting line or the second connecting line gradually increases.

[0200] In the embodiment, the liquid spraying area 20a is approximately located at the top of the air inlet channel 10c, that is, at the small-angle end of the pear-shaped air inlet channel 10c. In the air inlet channel 10c, the caliber gradually increases away from the first arc-shaped wall 10c1 along the median line of the first connecting line or the second connecting line.

[0201] That is, the caliber of the air inlet channel 10c changes in the same way as the size of the water mist surface away from the first arc-shaped wall 10c1 along the median line of the first connecting line or the second connecting line. Therefore, the water mist surface has a better covering effect on the air inlet channel 10c.

[0202] In other embodiments, referring to Figure 7 , the liquid spraying area 20a is arranged in a second area formed by the two linear extension walls 10c2, the first connecting line, and the second connecting line.

[0203] Here, the liquid spraying area 20a is approximately located in the middle region of the air inlet channel 10c. In this way, the embodiment is more suitable than the embodiment in which the liquid spraying area 20a is located at the center of the water mist surface.

[0204] In some embodiments, referring to Figure 3 or Figure 7 , the connecting line between the midpoint of the first connecting line and the midpoint of the second connecting line is a third connecting line, and the direction of the third connecting line intersects the height direction of the condenser 1.

[0205] The third line is Figure 3 Or Figure 7 The line shown in L3.

[0206] In this embodiment, the extension size of the air inlet channel 10c in the height direction of the condenser 1 can be controlled, thereby facilitating the control of the overall height of the clothes treatment apparatus.
