Description

Technical Field

[0002] At present, when clothing processing equipment such as a heat pump dryer is drying clothes, a heat exchange component is provided in the drying circulation air duct of the heat pump dryer. Therefore, the heat exchange component can convert the wet and cold airflow from the clothing processing chamber into a dry and hot airflow. The dry and hot airflow flows back into the clothing processing chamber and exchanges heat with the wet clothes in the clothing processing chamber to form a wet and cold airflow again. The wet and cold airflow flows out of the clothing processing chamber, and this cycle is repeated to dry the clothes.

[0003] However, when the airflow circulates in the clothing processing chamber, it will carry clothing debris. When the airflow carrying the debris flows back to the heat exchanger component, the heat exchanger component is prone to adhesion of the debris. If the debris on the heat exchanger component is not removed in time, it will not only produce odor, but also seriously affect the heat exchange performance. Utility Model Content

[0031] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0032] The inventors discovered that when drying clothes in a heat pump dryer, a heat exchange assembly is installed within the dryer's drying circulation duct. This heat exchange assembly converts the damp, cold airflow from the clothes processing chamber into a dry, hot airflow. The dry, hot airflow then flows back into the chamber, exchanging heat with the wet clothes inside, forming a damp, cold airflow again. The damp, cold airflow then flows out of the chamber, repeating this cycle to dry the clothes. Since the airflow within the chamber carries clothing debris, when it flows back to the heat exchange assembly, the debris easily adheres to the heat exchange assembly. Failure to promptly remove the debris from the heat exchange assembly can not only produce odor but also seriously affect heat exchange performance.

[0033] Please refer to Figures 1 to 2In order to solve the above technical problems, the present application proposes a nozzle 400 and a clothing processing device, wherein the clothing processing device includes a heat exchange component 200, the heat exchange component 200 includes an evaporator 210 and a condenser 220 that form a refrigerant circulation, and the nozzle 400 is used to flush the evaporator 210; the nozzle 400 has a water flow cavity 410, a water inlet 411 and a water outlet 3240, and the water inlet 411 and the water outlet 3240 are both connected to the water flow cavity 410. Along the preset direction A, the heat exchange component 200 is arranged on the nozzle 400. On one side, the nozzle 400 has a first surface 421 for facing the heat exchange component 200, and the first surface 421 has a first area 4211 and a second area 4212, pointing from the water inlet 411 to the direction of the water outlet 3240, and the first area 4211 and the second area 4212 are arranged in sequence, wherein the first area 4211 and the second area 4212 are used to be arranged opposite to the condenser 220 and the evaporator 210 respectively, and in the preset direction A, the second area 4212 is closer to the evaporator 210 than the first area 4211.

[0034] It can be understood that in the embodiment of the present application, along the preset direction A, the first surface 421 is a surface in the water flow cavity 410 of the nozzle 400 close to the heat exchange component 200, and the wall surface of the water flow cavity 410 close to the heat exchange component 200 can be set to a contoured surface similar to the first surface 421.

[0035] Based on the nozzle 400 and the clothing processing device of the embodiment of the present application, the first surface 421 of the nozzle 400 is set to face the heat exchange component 200, including a first area 4211 close to the water inlet 411 and a second area 4212 close to the water outlet 3240, and in a preset direction, the second area 4212 is closer to the evaporator 210 than the first area 4211, so that the second area 4212 has a sinking space toward the evaporator 210 compared with the first area 4211, so that the water flow cavity 410 close to the water outlet 3240 has a larger water outlet space, thereby preventing the water outlet 3240 from being blocked, so that the nozzle 400 can discharge water smoothly. In contrast, the first area 4211 corresponds to the condenser 220, and the portion of the nozzle 400 having the first area 4211 can avoid the condenser 220 in a preset direction, so that the side of the first area 4211 facing the condenser 220 has a larger installation space in the preset direction, which can be used to accommodate a larger condenser 220, thereby speeding up the heat exchange time and improving the heat exchange efficiency.

[0036] In some embodiments, please refer to Figure 3 and Figure 4Along the preset direction A, the distance between the first region 4211 and the second region 4212 is h1, where 2 mm ≤ h1 ≤ 6 mm. Within this distance range, it is convenient to set the relative distance between the first region 4211 and the second region 4212 appropriately, so that water can flow smoothly from the water inlet 411 to the water outlet 3240. Specifically, the first region 4211 has a first edge facing the second region 4212 and a second edge away from the second region 4212. The second region 4212 has a third edge facing the first region 4211 and a fourth edge away from the first region 4211. Here, h1 can be the distance between any two of the first edge, the second edge, the third edge, and the fourth edge in the preset direction A.

[0037] Optionally, the first edge of the first region 4211 is connected to the second region 4212 . In this case, at least one of the first region 4211 and the second region 4212 is an inclined surface inclined toward the side where the heat exchange assembly 200 is located. For example, the first area 4211 is an inclined surface inclined toward the side where the heat exchange component 200 is located, and the second area 4212 is a plane perpendicular to the preset direction A. Then, in the preset direction A, the distance from the second edge to the fourth edge is greater than the distance from the first edge to the fourth edge and the spacing is h1, and the distance from the third edge to the fourth edge is equal to 0; or, the second area 4212 is an inclined surface inclined toward the side where the heat exchange component 200 is located, and the first area 4211 is a plane perpendicular to the preset direction A. Then, in the preset direction A, the distance from the third edge to the fourth edge is h1, and the distance from the second edge to the fourth edge is equal to the distance from the first edge to the fourth edge; or, both the first area 4211 and the second area 4212 are inclined surfaces inclined toward the side where the heat exchange component 200 is located. Then, in the preset direction A, the distance from the second edge to the fourth edge is greater than the distance from the first edge to the fourth edge, the distance from the third edge to the fourth edge is greater than 0, and the distance from the second edge to the fourth edge is h1.

[0038] Optionally, the first region 4211 and the second region 4212 are both planes perpendicular to the preset direction A, that is, the first region 4211 and the second region 4212 are arranged in parallel, so the distance between the first region 4211 and the second region 4212 along the preset direction A is h1.

[0039] Among them, the height difference h1 between the first area 4211 and the second area 4212 can achieve a better drainage effect, facilitating water to flow from the water inlet 411 to the water outlet 3240 and be sprayed out from the water outlet 3240. The height difference between the first area 4211 and the second area 4212 can optimize the impact force of the water flow when cleaning the evaporator 210 to a certain extent, thereby improving the cleaning efficiency.

[0040] The minimum distance h1 between the first area 4211 and the second area 4212 is 2 mm, ensuring that the height of the sunken space in the second area 4212 is at least 2 mm. This increases the flow area of ​​the portion of the water flow chamber 410 corresponding to the second area 4212, preventing debris in the water flow from blocking the water outlet 3240. This also allows the size of the condenser 220 opposite the first area 4211 to be further increased. Furthermore, the maximum distance h1 between the first area 4211 and the second area 4212 is 6 mm, preventing the overall size of the nozzle 400 in the second area 4212 from being excessively large along the predetermined direction. This ensures that the nozzle 400 can effectively avoid the nozzle in the second area 4212 and prevents turbulence caused by the large height difference between the first area 4211 and the second area 4212.

[0041] It is understood that the first surface 421 further has a transition region 4213, which connects between the first region 4211 and the second region 4212 to guide water flow from the first region 4211 to flow toward the second region 4212. The transition region can have one of the following forms: the transition region 4213 is an inclined surface, that is, it is inclined toward the side where the heat exchange component 200 is located along the direction from the water inlet 411 to the water outlet 3240; the transition region 4213 is an arcuate surface, that is, it is a convex arcuate surface that bends toward the side where the heat exchange component 200 is located; the transition region 4213 is a stepped surface, that is, the transition region is parallel to the preset direction A, connects between the first region 4211 and the second region 4212, and the three together form a step.

[0042] In some embodiments, when the transition region 4213 is an inclined surface, it can smoothly connect the first region 4211 and the second region 4212, thereby smoothly guiding the water flow from the first region 4211 to the second region 4212, thereby effectively reducing the impact and turbulence of the water flow. When the transition region 4213 is an arcuate surface, it can also achieve a smooth transition effect. The arcuate transition region 4213 can adjust the angle of the water flow to a certain extent, allowing the water flow to enter the second region 4212 in a more gentle manner. When the transition region 4213 is a stepped surface, it can maximize the capacity of the portion of the water flow chamber 410 corresponding to the second region 4212, preventing clogging of the water outlet 3240.

[0043] Please refer to Figure 2 and Figure 3The first area 4211 is a flat surface, and the second area 4212 is a flat surface. The first area 4211 and the second area 4212 are arranged in parallel, making the overall structure of the nozzle 400 more compact and consistent, minimizing the space occupied by the nozzle 400 in the clothing processing device, and improving the installation compatibility of the nozzle 400 with other components. Because the first surface 421 is positioned toward the heat exchange component 200, the planar arrangement of the first area 4211 and the second area 4212 facilitates assembly with the heat exchange component 200 and provides high installation stability. Furthermore, the planar arrangement of the first area 4211 and the second area 4212 facilitates cleaning and is less likely to accumulate solid matter such as lint, effectively preventing clogging of the water outlet 3240.

[0044] Please refer to Figure 2 and Figure 3 The nozzle 400 includes a first main board 420 and a second main board 430. The first main board 420 has a first surface 421 and a water outlet 3240. The second main board 430 is arranged opposite to the first main board 420 and is connected to the first main board 420 to jointly construct a water outlet cavity 410. Among them, along the direction from the water inlet 411 to the water outlet 3240, the second main board 430 extends obliquely toward the direction close to the first main board 420. On the one hand, the connection between the second main board 430 and the first main board 420 at a certain degree of inclination angle can help guide the water flow and reduce the turbulence of the water flow at the inlet, ensuring that the water flow can flow smoothly in the water flow cavity 410. On the other hand, since the second main board 430 and the first main board 420 are close to each other along the direction from the water inlet 411 to the water outlet 3240, the overall structure of the nozzle 400 is more compact, which can effectively reduce the space occupied by the nozzle 400, thereby improving the compatibility of the nozzle 400 with other components.

[0045] Please refer to Figure 5The water inlet 411 points toward the water outlet 3240 . The dimensions of the first main plate 420 and the second main plate 430 in the width direction Y gradually increase until both the dimensions of the first main plate 420 and the second main plate 430 in the width direction Y reach their maximum dimensions. Thereafter, the dimensions of the first main plate 420 and the second main plate 430 in the width direction Y gradually decrease. The width direction Y is perpendicular to both the preset direction and the direction in which the water inlet 411 points toward the water outlet 3240 . It is understood that as water flows from the water inlet 411 toward the water outlet 3240 , the dimensions of the first main plate 420 and the second main plate 430 in the width direction Y gradually increase, causing the dimension of the water flow in the width direction Y to also increase. This ensures that the water flow has a larger dimension in the width direction Y when it is discharged, forming a water curtain along the width direction Y. This increases the flushing range of the evaporator 210 by the nozzle 400 , improving cleaning efficiency while also ensuring the coverage of the nozzle 400 during cleaning, ensuring that all locations on the surface of the evaporator 210 are effectively flushed.

[0046] Furthermore, in an embodiment of the present application, near the water outlet 3240, the dimensions of the first main board 420 and the second main board 430 in the width direction Y reach a maximum dimension, so that the dimension of the water curtain of the water outlet 3240 along the width direction Y is maximized, thereby ensuring that the coverage range of the nozzle 400 during cleaning is large enough, and continuing along the width direction Y, passing the water outlet 3240, the dimensions of the first main board 420 and the second main board 430 in the width direction Y gradually decrease, thereby reducing the manufacturing materials of the first main board 420 and the second main board 430 and reducing manufacturing costs. In addition, the reduction in the dimensions of the first main board 420 and the second main board 430 in the width direction Y can also speed up the water flow rate, ensuring that the initial velocity of water when it is discharged from the water outlet 3240 is within a certain range, thereby improving the cleaning efficiency.

[0047] Please refer to Figure 4 and Figure 5 In some embodiments, the nozzle 400 further includes a second flange 3254 and a first flange 3242. The second flange 3254 is used to connect the edge of the second main board 430 and protrude from the second main board 430 in a direction close to the first main board 420. The second flange 3254 is provided with a mating slot 3254a. The first flange 3242 is connected to the edge of the first main board 420 and protrudes from the first main board 420 in a direction close to the second main board 430. A plurality of protrusions 3243 are arranged at intervals on the first flange 3242, and the protrusions 3243 are snapped into the mating slot 3254a.

[0048] The second flange 3254 and the first flange 3242 respectively protrude in a direction approaching the first main board 420 and the second main board 430 to connect and assemble the first main board 420 and the second main board 430. This helps widen the size of the water flow chamber 410 in the predetermined direction A and improves the connection strength between the first main board 420 and the second main board 430. Furthermore, the second flange 3254 has multiple mating slots 3254a, while the first flange 3242 is provided with multiple corresponding protrusions 3243. During actual installation, the mating slots 3254a and the protrusions 3243 can be correspondingly snapped into place, ensuring the reliability of the connection between the second main board 430 and the first main board 420 and further improving the strength of the connection structure.

[0049] At the same time, the snap-fit ​​assembly between the second main board 430 and the first main board 420 is convenient for assembly and disassembly, which can facilitate the disassembly and separation of the second main board 430 and the first main board 420 and their cleaning and maintenance, thereby increasing the service life of the nozzle 400. Regular cleaning can also prevent the nozzle 400 from being clogged and ensure the normal operation of the nozzle 400.

[0050] In order to facilitate the assembly between the second main board 430 and the first main board 420, the first flange 3242 is provided with notches 3246 on both sides of the protrusion 3243. The notches 3246 are located on both sides of the protrusion 3243 along the direction from the water inlet 411 to the water outlet 3240, thereby reducing the force on both sides of the protrusion 3243, making the protrusion 3243 more likely to deform when under pressure, thereby making it easier to cooperate with the slot 3254a for installation, reducing the installation resistance, and further improving the convenience of disassembly and assembly.

[0051] Further, in Figure 3 and Figure 5 In the nozzle 400, the nozzle 400 also includes a guide plate 3241, which is located in the water flow cavity 410. The guide plate 3241 is connected to the inner wall of the first main board 420. In the flow direction of the water flow, the guide plate 3241 helps to guide the flow path of the water flow in the water flow cavity 410. On the one hand, it reduces the turbulence and vortex inside the water flow cavity 410, reduces the energy loss of the water flow, and enables the water flow to flow more smoothly and steadily from the water inlet 411 to the water outlet 3240. On the other hand, the guide plate 3241 can be used to The distribution of water flow is controlled so that the water flow is evenly distributed in the water flow cavity 410, thereby ensuring uniform and smooth water output, and the guide plate 3241 can also enhance the structural stability of the nozzle 400 to a certain extent. The guide plate 3241 is connected to the first main board 420 and plays a certain supporting effect in the water flow cavity 410. It can be used to resist and slow down the impact of water flow, thereby protecting the water flow cavity 410 and reducing the impact of water flow impact on the connection between the second main board 430 and the first main board 420.

[0052] To address different application scenarios, multiple guide plates 3241 are provided. The water outlet 3240 is elongated and extends along the width direction Y. The multiple guide plates 3241 are spaced apart along the width direction Y, wherein the width direction is perpendicular to both the preset direction and the direction from the water inlet 411 to the water outlet 3240. In the embodiment of the present application, the multiple guide plates 3241 are spaced apart along the width direction, which helps optimize the distribution of water flow along the width direction. Each guide plate 3241 guides the water flow. When the water flows through the guide plates 3241, it is divided into multiple small streams that flow along the channels between the guide plates 3241. This allows the water flow to be evenly dispersed along the width direction Y to the entire water outlet 3240, making the water flow more uniform and stable along the width direction, preventing water flow from concentrating in certain areas and being lost in other areas, and reducing blind spots in the water outlet.

[0053] At the same time, multiple guide plates 3241 correspond to the long strip water outlet 3240. In some embodiments, the guide plates 3241 are located upstream of the water outlet 3240 along the water flow direction and are arranged close to the water outlet 3240. The width dimensions of the second main board 430 and the first main board 420 in the direction from the water inlet 411 to the water outlet 3240 gradually increase, and the water flow is diverted at a position close to the water outlet 3240, which can ensure the effectiveness of the water diversion. The state of the water when flowing to the water outlet 3240 will be more uniform and stable, which will help to form a continuous water curtain and achieve more comprehensive cleaning of the evaporator 210.

[0054] Second, please refer to Figure 6 An embodiment of the present application provides a clothing processing device, which may be a clothes dryer, a drying machine, a washing machine integrated with a washer and dryer, etc. The present application does not limit this, as long as it can dry clothes.

[0055] In the present application, the clothing processing device includes the above-mentioned nozzle 400. The specific structure of the nozzle 400 refers to the above-mentioned embodiment. Since the clothing processing device adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0056] Please refer to Figure 1 and Figure 6In some embodiments of the present application, the clothing processing device includes an inner barrel 100, which is connected to the gas flow channel. The evaporator 210 and the condenser 220 are both located in the gas flow channel of the clothing processing device, wherein, with the inner barrel 100 as the starting point, along the flow direction of the gas, the evaporator 210 is located upstream of the condenser 220, and the airflow flowing out of the inner barrel 100 first contacts the evaporator 210, so the side of the evaporator 210 close to the airflow is prone to hair debris attached to it. The water outlet 3240 of the nozzle 400 in the present application is used to correspond to the side of the evaporator 210 close to the airflow and flush this side, so that the hair debris attached to the evaporator 210 can be effectively removed, thereby ensuring the cleanliness of the evaporator 210 and improving the operating efficiency of the evaporator 210.

[0057] In addition, please refer to Figure 1 and Figure 2 The above-mentioned clothing processing device also includes a cavity shell 500 and a heat exchange component 200. The cavity shell 500 has a heat exchange flow channel. The heat exchange component 200 is arranged in the heat exchange flow channel, including an evaporator 210 and a condenser 220 that form a refrigerant circulation.
