An embodiment of the present application provides a condensation device 10 . Please refer to FIGS. 1 to 8 . The condensation device 10 includes a condensation tube 11 and a flow guide assembly 12 .

Please refer to Figures 2 to 5. The condensation pipe 11 has a water inlet 11c, a drain 11d, an air inlet 11a and an air outlet 11b. A condensate flow path extending vertically downward is formed between the water inlet 11c and the drain 11d. That is to say, the water inlet 11c of the condensation pipe 11 is located on the upper side of the drain outlet 11d, and the condensate flow path formed between the water inlet 11c and the drain outlet 11d extends from top to bottom, or in other words, the condensate flows into the water inlet 11c. The condensate in the tube 11 can flow from top to bottom along the condensate flow path under the action of its own gravity, and flow out from the drain port 11d. An air flow path extending laterally is formed between the air inlet 11a and the air outlet 11b. That is to say, the air inlet 11a and the air outlet 11b are respectively located on opposite sides of the condensation pipe 11 in the transverse direction. The air flowing into the condensation pipe 11 from the air inlet 11a The air flow can flow laterally along the air flow path and flow out from the air outlet 11b. It should be noted that the air flow path described here only needs to extend transversely, and is not limited to flowing from a specified side to a specified other side. The condensate flow path intersects the air flow path, that is to say, the air flow path needs to pass through the condensate flow path, that is, the air flow passes through the condensate when flowing along the air flow path.

The specific composition of the condensate is not limited and can be water or other types of liquids.

The condensing device 10 is used to dehumidify and cool the hot and humid airflow. Specifically, the hot and humid airflow enters the condensation pipe 11 from the air inlet 11a and flows along the airflow flow path, and the condensate liquid enters the condensation pipe 11 from the water inlet 11c and flows along the condensate flow path. Flow, when the hot and humid airflow passes through the condensate, the hot and humid airflow exchanges heat with the condensate. The condensate absorbs the heat of the hot and humid airflow. The water vapor in the hot and humid airflow is precipitated from the airflow due to cooling and condenses into water droplets. The water droplets mix into the condensation. In the liquid, it is finally discharged from the water outlet. In this way, the effect of dehumidification and cooling of the hot and humid airflow is achieved, so that the gas discharged from the air outlet 11b is a relatively low-temperature and dry airflow that has been cooled and dehumidified. It should be noted that the low-temperature dry air flow is relative to the humid and hot air flow, and the temperature of the low-temperature dry air flow is lower than the temperature of the humid and hot air flow. The low temperature in the embodiment of the present application may be room temperature.

The condensation device 10 of the embodiment of the present application can be used in any appropriate occasion. Illustratively, the embodiment of the present application is described by taking the condensation device 10 being applied to a laundry treatment equipment as an example.

Illustratively, please refer to Figure 1. This embodiment of the present application provides a clothes treatment device, including a cylinder assembly 20, a filter device 30, an air guide device 40, and the condensation device 10 of any embodiment of the present application. The cylinder assembly 20 is provided with a clothes treatment chamber and an air inlet and an air outlet connected with the clothes treatment chamber; the filter device 30 connects the air outlet and the air inlet 11a; the air guide device 40 connects the air outlet 11b and the air inlet. It should be noted that the air guide device 40 is equipped with a fan and a heater.

Specifically, the air flow channel 11e of the condensation device 10 shown in Figure 1 is arranged along the left and right directions of the barrel assembly 20. That is to say, most of the area of the air flow channel 11e extends along the left and right sides of the barrel assembly 20. In some embodiments, , the air flow channel 11e of the condensation device 10 may also be arranged along the axial direction of the cylinder assembly 20.

The drain port 11d of the condensation device 10 shown in Figure 1 is located on the axial rear side of the barrel assembly 20. That is to say, part of the structure of the condensation device 10 can be extended to the axial rear side of the barrel assembly 20 to facilitate drain.

An air flow circulation channel is formed in the clothes processing equipment, and the air guide device 40 guides the dry hot air flow into the clothes processing cavity through the air inlet. In the clothes processing cavity, the dry hot air flow flows through the surface of the wet clothes and exchanges heat and moisture with the wet clothes. It absorbs the moisture in the clothes and turns it into a hot and humid airflow. During the drying process, the lint and impurities produced by the clothes are mixed into the hot and humid airflow. The hot and humid airflow carries the lint and impurities and flows out through the air outlet in turn and then enters the filter device 30 for filtration. , the filtered hot and humid airflow can remove most of the lint and impurities, but a small amount of smaller lint will enter the condensation device 10 from the air inlet 11a along with the hot and humid airflow. The hot and humid air flows through the condensation device 10 The condensate is condensed and dehumidified to form a low-temperature dry airflow. The low-temperature dry airflow enters the air guide 40 from the air outlet 11b and is heated by the heater in the air guide 40 to form a dry hot airflow. The hot dry airflow enters the clothes processing chamber again, and the lint trapped in the hot and humid airflow is mixed with the condensed water into the condensate, and is discharged through the drain port 11d. This cycle operates to achieve continuous and efficient drying and filtering of the clothes. crumbs.

Referring to Figures 3 to 5, the flow guide assembly 12 is disposed at the intersection of the condensate flow path and the airflow flow path. The flow guide assembly 12 includes a flow collecting plate 121 with a flow collecting groove 121a. The flow guide assembly in Figure 5 12 is provided with a plurality of flow collecting plates 121, and the plurality of flow collecting plates 121 are arranged at intervals in the condensation tube 11. In some embodiments, only one flow collecting plate 121 may be provided. The collecting groove 121a is used to collect the condensate flowing along the condensate flow path, and guide the condensate to overflow from at least one of the two opposite sides of the collecting groove 121a along the air flow direction. It should be noted that the airflow direction refers to the direction in which the airflow flows along the airflow path.

Specifically, when the condensate flows from top to bottom along the condensate flow path, it will flow through the collecting plate 121. Please refer to FIG. 5. The condensate flowing through the collecting plate 121 first flows into the collecting groove 121a. When there is too much condensate in the flow groove 121a, the excess condensate will overflow from the flow collecting groove 121a. In the flow guide assembly 12 shown in Figure 5, the flow collecting grooves 121a on each flow collecting plate 121 are configured to guide The condensate overflows from opposite sides of the collecting groove 121a along the air flow direction. In some embodiments, the collecting grooves 121a on each collecting plate 121 can also be configured to guide the condensate from the collecting groove 121a along the air flow. One of the two opposite sides in the flow direction overflows, or the condensate can also be guided by the condensate grooves 121a on a part of the condensing plate 121 to overflow from the opposite sides of the condensate groove 121a along the air flow direction, and the other part can be concentrated. The collecting groove 121a on the plate 121 guides the condensate to overflow from one of the two opposite sides of the collecting groove 121a along the air flow direction. When the flow guide assembly 12 has only one flow collecting plate 121, the flow collecting plate 121 can be configured to guide the condensate to overflow from the opposite sides of the collecting groove 121a along the air flow direction, or can be configured to guide the condensate to escape from the collecting flow. The groove 121a overflows along one of the two opposite sides in the air flow direction.

By collecting the condensate, the condensation tank 121a can not only slow down the flow rate of the condensate, but also enable part of the hot and humid airflow flowing along the air flow path to contact the condensate in the condensation tank 121a, and the condensation liquid that overflows from the condensation tank 121a can be The condensate will form a water curtain during the falling process. When the hot and humid air flowing along the air flow path passes through the water curtain, it can also fully contact the water curtain. That is to say, the condensate and condensate collected in the condensation tank 121a The water curtain formed during the falling process after overflowing from the condensing tank 121a jointly increases the contact area between the hot and humid airflow and the condensate, thereby enabling the hot and humid airflow to fully exchange heat with the condensate, thereby improving the condensation effect. .

In addition, since the hot and humid air flow can fully contact the condensate and the water curtain collected in the condensation tank 121a, the lint trapped in the hot and humid air flow is more likely to be mixed into the condensate along with the condensed water. Therefore, It can also improve the filtering and dandruff removal effect.

It should be noted that the condensation device in the related art is generally arranged vertically, and the water inlet, drain, air inlet and air outlet are all arranged vertically. Among them, the air inlet and drain are arranged at a low place, and the air outlet and water inlet are arranged vertically. It is installed at a high place, that is to say, the condensate entering the condensing device from the water inlet flows vertically downward, while the hot and humid airflow entering the condensing device from the air inlet flows upward vertically, and the hot and humid airflow flows vertically upward. During the process, the condensate flows vertically downward to achieve the condensation effect. However, this type of condensation device requires a large condensate drop and a large air flow distance. Therefore, the condensation device has a relatively large volume and many structural restrictions, making it difficult to guarantee the condensation effect.

In the condensation device according to the embodiment of the present application, the condensate flow path extends downward vertically, and the air flow path extends transversely. At the same time, a flow guide with a flow collecting plate is provided at the intersection of the condensate flow path and the air flow path. Assembling the assembly, the collecting groove of the collecting plate can collect the condensate, and guide the condensate to overflow from at least one of the opposite sides of the collecting groove along the air flow direction to form a water curtain for the hot and humid air to pass through. Since the air flow path of the condensation device extends in the transverse direction, the condensation device does not require a large condensate drop, nor does it require a large air flow distance in the vertical direction. That is to say, the condensation device is not affected by the condensate. Affected by the height difference and air flow distance, the structure is not only relatively compact, but also flexible and can adapt to more functional structures. The condensate collected in the collecting tank and the condensate overflowing from the collecting tank are in the process of falling. The formed water curtain can increase the contact area between the hot and humid airflow and the condensate, so that the hot and humid airflow can fully exchange heat with the condensate, thereby improving the condensation effect. That is to say, the condensation device of the embodiment of the present application not only has a relatively compact structure, but also has a good condensation effect.

The relative height between the air inlet 11a and the air outlet 11b in the embodiment of the present application can be adjusted as needed. For example, please refer to Figures 2 and 3. The highest point of the air inlet 11a can be set higher than the lowest point of the air outlet 11b. The setting height of the point is that at least some areas of the air inlet 11a are set higher than the air outlet 11b. As shown in Figures 2 and 3, only some areas of the air inlet 11a are set higher than the air outlet 11b, which is equivalent to The height difference between the air inlet 11a and the air outlet 11b is small, which is beneficial to reducing the height dimension of the condenser pipe 11 and saving the installation space of the condenser pipe 11 in the height direction. It should be noted that when the air inlet 11a is set up vertically or at an angle as shown in Figures 2 and 3, the air inlet 11a has an obvious highest point and a lowest point, while when the air inlet 11a is set up horizontally (that is, as shown in Figure 2 2 and Figure 3 The air outlet 11b is set in the same manner as shown), the air inlet 11a has only one setting height, and the setting height is equal to the setting height of the highest point of the air inlet 11a. Similarly, when the air outlet 11b is set vertically or tilted, the air outlet 11b has obvious highest points and lowest points. When the air outlet 11b is set horizontally as shown in Figures 2 and 3, the air outlet 11b has only one setting. The set height is equal to the set height of the lowest point of the air outlet 11b.

In some embodiments, the height of the highest point of the air inlet 11a may be equal to the height of the lowest point of the air outlet 11b, or the height of the highest point of the air inlet 11a may be lower than the lowest point of the air outlet 11b. Set height.

The position of the water inlet 11c in the embodiment of the present application can be adjusted as needed. Preferably, please refer to Figures 2 to 4. The water inlet 11c can be provided on the top wall of the condensation pipe 11. In Figures 2 to 4, the condensation A water inlet pipe is provided on the top wall of the pipe 11, and the entrance of the water inlet pipe is the water inlet 11c. In some embodiments, a water inlet 11c that penetrates the top wall may also be formed on the top wall.

The relative height between the water inlet 11c and the air outlet 11b can also be adjusted as needed. For example, please refer to Figures 2 to 4. The setting height of the highest point of the water inlet 11c can be higher than the setting height of the lowest point of the air outlet 11b. , that is to say, at least some areas of the water inlet 11c are set higher than the air outlet 11b. It should be noted that the definition of the highest point of the water inlet 11c is the same as the definition of the highest point of the air inlet 11a. The water inlet 11c and the air outlet 11b shown in Figures 2 to 4 are both set horizontally. Although the entire water inlet 11c is set higher than the air outlet 11b, the height difference between the water inlet 11c and the air outlet 11b It is also relatively small. Therefore, it is also beneficial to reduce the height dimension of the condenser pipe 11 and save the installation space of the condenser pipe 11 in the height direction.

In some embodiments, the setting height of the highest point of the water inlet 11c may also be equal to the setting height of the lowest point of the air outlet 11b, or the setting height of the highest point of the water inlet 11c may also be lower than the lowest point of the air outlet 11b. Set height.

In one embodiment, please refer to FIGS. 3 to 5 , the condenser tube 11 may form an airflow channel 11e having an air inlet 11a and an air outlet 11b. That is to say, the airflow path is located in the airflow channel 11e, and the water inlet 11c may be located in the airflow channel 11e. On the upper side of the channel 11e, the drainage outlet 11d may be located on the lower side of the airflow channel 11e. The height of the drainage outlet 11d relative to the water inlet 11c is higher than that of the airflow channel 11e. The installation height is lower than the installation height of the air flow channel 11e.

In one embodiment, please refer to Figure 3. A partition wall 11f can be provided in the condensation tube 11. The partition wall 11f separates the air flow channel 11e in the condensation tube 11 and a drainage channel 11g located below the air flow channel 11e, wherein the drainage channel 11g There is a drain port 11d, that is, a part of the condensate flow path passes through the drain channel 11g. Part of the edge of the partition wall 11f in Figure 3 is spaced apart from the inner wall of the condenser tube 11, so that a water opening connecting the air flow path and the drainage channel 11g is formed at the space. In some embodiments, the water opening can also be directly formed on On the partition wall 11f. After the condensate passes through the air flow path, the condensate flows from the water outlet into the drainage channel 11g and is discharged from the drainage outlet 11d. The drainage channel 11g can serve to collect condensate so that the condensate can be discharged from the drain outlet 11d in a timely manner.

In addition, please refer to Figures 4 and 5. The flow guide assembly 12 can be located downstream of the water outlet along the air flow direction, which means that the hot and humid air first flows above the water outlet and then passes through the condensate. A partial area of the side of the partition wall 11f facing the guide assembly 12 can form a drainage surface 11h. The drainage surface 11h guides the condensate flow path to extend toward the water outlet. The drainage surface 11h in Figures 4 and 5 is a curved surface. In some embodiments, The drainage surface 11h can also be an inclined plane. After the condensate flowing through the drainage assembly 12 falls on the drainage surface 11h, it can flow to the water outlet along the drainage surface 11h, which is equivalent to the flow direction of the condensate flowing along the drainage surface 11h. It is opposite to the flow direction of the air flow, thereby preventing the condensate from flowing to the air outlet 11b along with the condensed low-temperature dry air flow as much as possible.

In an embodiment, please refer to Figures 2 and 3. The airflow channel 11e may also have a first extension section 11e1 and a second extension section 11e2; the second extension section 11e2 is connected to the first extension section 11e1 and extends toward the first extension section 11e1. extends to one side of One end of 11e2 away from the first extension section 11e1 has an air outlet 11b, and the condensate flow path passes through the first extension section 11e1.

Specifically, for convenience of description, it can be considered that the first extension section 11e1 extends along the length direction of the condensation pipe 11, and the second extension section 11e2 extends along the width direction of the condensation pipe 11. Providing the second extension section 11e2 is equivalent to saving condensation. The length of the tube 11 is such that the overall structure of the condensing device 10 can be more compact. In addition, the low-temperature dry air flow formed after condensation may also contain tiny droplets formed by a small amount of condensate. Therefore, by providing the first extension section 11e1 and the second extension section 11e2, a corner can be formed at the connection between the first extension section 11e1 and the second extension section 11e2. When the low-temperature drying airflow flows through the first extension section 11e1 and the second extension section When 11e2 is connected, the tiny droplets contained in the low-temperature drying air flow can be thrown to the side wall of the air flow channel 11e under the action of centrifugal force. This can also prevent the condensate from flowing to the air outlet 11b with the air flow as much as possible.

The focusing groove 121a can be formed in various ways. For example, please refer to FIG. 4 . The top surface of the focusing plate 121 defines the focusing groove 121a. That is to say, a non-planar top surface can be used to construct the focusing groove 121a. For example, the flow channel 121a can be formed by bending the flow collecting plate 121 so that the top end surface forms the flow channel 121a. Specifically, the top end surface of the flow collecting plate 121 shown in FIG. 4 is a curved surface that is bent toward the bottom end surface of the flow collecting plate 121. In some embodiments, the top end surface may also include at least two inclined surfaces, and the inclined surfaces may both be inclined. A part of the plane may be an inclined plane, and the other part may be an inclined curved surface, and the inclined planes may be connected in sequence, or the flow collecting groove 121a may be defined.

In some embodiments, a partial area of the top of the flow collecting plate 121 may be recessed to form a flow collecting groove 121a.

The relative position of the flow collecting plate 121 and the water inlet 11c can be determined as needed, as long as the condensate flowing into the condensation pipe 11 from the water inlet 11c can flow into the flow collecting groove 121a. For example, please refer to Figure 4, flow collecting. The relative position of the plate 121 and the water inlet 11c can be: the axial centerline of the water inlet 11c passes through the flow collecting plate 121, that is, the first flow collecting plate 121b, the second flow collecting plate 121c and the third flow collecting plate in Figure 4 How the 121d is set up. In some embodiments, the relative position of the flow collecting plate 121 and the water inlet 11c may also be: the flow collecting plate 121 is located on one of the two opposite sides of the axial centerline of the water inlet 11c along the air flow direction.

The plurality of flow collecting plates 121 can be arranged at intervals in the condenser tube 11 in various ways. For example, please refer to FIGS. 3 to 7 . Each flow collecting plate 121 can be arranged vertically in layers, that is to say, Each flow collecting plate 121 can be arranged at intervals along the vertical direction to form a multi-layer structure.

Further, please refer to FIGS. 3 to 7 . For the multi-layer structure of the flow collecting plates 121 , the relative positions of at least part of the vertically adjacent flow collecting plates 121 can satisfy: along the condensate flow direction, the downstream flow collecting plates 121 are The collecting groove 121a of 121 can receive the overflowing water from the collecting groove 121a of the upstream collecting plate 121. At least part of the condensate, that is to say, the relative positions of at least two vertically adjacent flow collecting plates 121 are such that at least part of the condensate overflowing from the collecting groove 121a of one flow collecting plate 121 can flow to the flow collecting groove 121a of one flow collecting plate 121. In the flow collecting groove 121a of another flow collecting plate 121 on the lower side of the flow collecting plate 121 and adjacent thereto.

Specifically, taking FIG. 4 and FIG. 5 as an example, three flow collecting plates 121 are shown in FIG. 4 and FIG. 5 . The three flow collecting plates 121 are arranged in sequence from top to bottom in the vertical direction. For convenience of description, they can be These three flow collecting plates 121 are respectively called the first flow collecting plate 121b, the second flow collecting plate 121c and the third flow collecting plate 121d. In Figures 4 and 5, the first flow collecting plate 121b and the second flow collecting plate 121c are arranged vertically adjacent to each other, and the first flow collecting plate 121b is located upstream of the second flow collecting plate 121c along the condensate flow direction. The horizontal projection of one flow collecting plate 121b is located in the horizontal projection area of the flow collecting groove 121a of the second flow collecting plate 121c. It should be noted that the horizontal projection refers to the projection on a horizontal plane perpendicular to the vertical direction. That is to say, the condensate overflowing from the collecting groove 121a of the first collecting plate 121b can flow from the opposite sides of the collecting groove 121a of the first collecting plate 121b along the air flow direction to the second collecting plate 121c. In the collecting groove 121a of the first collecting plate 121b, it is equivalent to all the condensate overflowing from the collecting groove 121a of the first collecting plate 121b flowing into the collecting groove 121a of the second collecting plate 121c. Similarly, the second collecting plate 121c 121c and the third flow collecting plate 121d are arranged vertically adjacent to each other, and the second flow collecting plate 121c is located upstream of the third flow collecting plate 121d along the condensate flow direction, and the horizontal projection of the second flow collecting plate 121c is located at the third flow collecting plate 121c. Within the horizontal projection area of the flow plate 121d, it is equivalent to the condensate overflowing from the flow collecting groove 121a of the second flow collecting plate 121c also flowing into the collecting groove 121a of the third flow collecting plate 121d.

It should be noted that only a part of the condensate overflowing from the collecting groove 121a of one flow collecting plate 121 may flow to the collecting groove 121a of another flow collecting plate 121 located below and adjacent to the flow collecting plate 121. For example, in another embodiment, please refer to FIG. 6 . For convenience of description, the opposite sides of the condensation device 10 along the airflow direction may be referred to as the first side and the second side respectively. In FIG. 6 , the condensation device 10 is The side located upstream in the air flow direction is called the first side, and the side of the condensing device 10 located downstream in the air flow direction is called the second side. In some embodiments, the condensing device 10 can also be located upstream in the air flow direction. One side is called the second side, and the side of the condensing device 10 located downstream in the air flow direction is called the first side. The positions corresponding to the first side and the second side can be interchanged. The horizontal projection of the first side of the first flow collecting plate 121b in Figure 6 is located within the horizontal projection area of the flow collecting groove 121a of the second flow collecting plate 121c. The first flow collecting plate The horizontal projection of the second side of 121b and the horizontal projection of the second side of the second collecting plate 121c are both located within the horizontal projection area of the collecting groove 121a of the third collecting plate 121d, which is equivalent to the condensate flowing from the first collecting plate 121d. After overflowing from the collecting groove 121a of the plate 121b, the condensate flowing down from the first side of the first collecting plate 121b flows into the collecting groove 121a of the second collecting plate 121c. The condensate flowing down from both sides flows into the collecting groove 121a of the third collecting plate 121d, and flows into the collecting groove 121a of the second collecting plate 121c. The condensate flows from the collecting groove 121a of the second collecting plate 121c. After overflowing, the condensate flowing down from the second side of the second collecting plate 121c also flows into the collecting groove 121a of the third collecting plate 121d, and the condensate flowing down from the first side of the second collecting plate 121c Then it does not flow into the flow collecting groove 121a of the third flow collecting plate 121d.

In the flow guide assembly 12 shown in FIG. 4 and FIG. 6 , the flow collecting groove 121 a of the downstream flow collecting plate 121 can absorb at least the flow collecting groove 121 a of the adjacent upstream flow collecting plate 121 that overflows. Part of the condensate. In another embodiment, please refer to Figure 7. The relative positions of the first flow collecting plate 121b, the second flow collecting plate 121c and the third flow collecting plate 121d can also be: the third flow collecting plate of the first flow collecting plate 121b. The horizontal projection of one side is located within the horizontal projection area of the flow collecting groove 121a of the second flow collecting plate 121c, and the horizontal projection of the second side of the first flow collecting plate 121b is located at the level of the flow collecting groove 121a of the third flow collecting plate 121d. In the projection area, the horizontal projection of the second side of the second flow collecting plate 121c is staggered from the horizontal projection of the first side of the third flow collecting plate 121d. That is to say, the flow collecting groove 121a of the first flow collecting plate 121b overflows. After the condensate flows down from the first side of the first flow collecting plate 121b, it can flow into the collecting groove 121a of the second flow collecting plate 121c, and the condensate flowing down from the second side of the first flow collecting plate 121b can flow into into the collecting groove 121a of the third collecting plate 121d. However, after the condensate overflowing from the collecting groove 121a of the second collecting plate 121c flows down from the second side of the second collecting plate 121c, it does not flow to the third collecting plate 121c. The flow collecting groove 121a of the third flow collecting plate 121d avoids the third flow collecting plate 121d and continues to flow downward. That is to say, the flow collecting groove 121a of the second flow collecting plate 121c can connect the adjacent flow collecting plate 121a and is located upstream. Part of the condensate overflowing from the collecting groove 121a of the first collecting plate 121b, however, the collecting groove 121a of the third collecting plate 121d does not connect the collecting groove 121a of the adjacent second collecting plate 121c located upstream. Part of the condensate overflowing from the flow channel 121a corresponds to the relative position of only some of the vertically adjacent flow collecting plates 121 among the plurality of flow collecting plates 121 satisfying: along the direction of condensate flow, the position of the downstream flow collecting plate 121 is The collecting groove 121a can receive at least part of the condensate that overflows from the collecting groove 121a of the upstream collecting plate 121.

The collecting groove 121a of the collecting plate 121 located downstream in the condensate flow direction receives at least part of the condensate overflowing from the collecting groove 121a of the adjacent collecting plate 121 located upstream. A water curtain is formed between the two condensing plates 121, which can also slow down the flow rate of the condensate, thereby further improving the condensation, filtration and chip removal effects. Especially when the condensation grooves 121a of at least part of the condensation plates 121 among the plurality of condensation plates 121 can also guide the condensate to flow to opposite sides of the condensation groove 121a along the air flow direction, the condensation and filtration of the condensation device 10 The dandruff removal effect can be greatly improved.

In addition, please refer to Figure 7. Although the collecting groove 121a of the third collecting plate 121d in Figure 7 does not receive the condensate overflowing from the collecting groove 121a of the adjacent second collecting plate 121c located upstream, However, after the condensate overflowing from the collecting groove 121a of the second collecting plate 121c flows down from the second side of the second collecting plate 121c, it also forms a separate water curtain. That is to say, as shown in Figure 4 Compared with the flow guide assembly 12, the flow guide assembly 12 shown in FIG. 7 increases the number of water curtains on the lower side of the third flow collecting plate 121d, thereby improving the condensation, filtration and chip removal effects of the condensation device 10.

The multi-layer structure used in the flow guide assembly 12 shown in Figures 4 to 7 is that only one flow collecting plate 121 is provided on each layer. In another embodiment, please refer to Figure 8, the flow guide assembly 12 can also be multiple. Some of the flow collecting plates 121 among the flow collecting plates 121 are arranged in layers along the vertical direction, and some of the flow collecting plates 121 are arranged at intervals along the transverse direction. That is to say, the flow guide assembly 12 shown in Figure 8 also adopts a multi-layer structure, except that Compared with the air guide assembly 12 shown in FIGS. 4 to 7 , at least one layer of the air guide assembly 12 shown in FIG. 8 can be provided with at least two flow collecting plates 121 , and at least two flow collecting plates 121 on the same layer. Set at horizontal intervals. It should be noted that the flow guide assembly 12 shown in FIG. 8 can use the flow collecting plate 121 described in any of the previous embodiments, which will not be described again.

In one embodiment, please refer to FIGS. 3 to 8 . The guide assembly 12 can also be provided with a guide plate 122 . Similar to the flow collecting plate 121 , the guide plate 122 can also guide the condensate toward the guide plate 122 along the direction of the air flow. At least one of the two opposite sides flows, but the flow guide plate 122 is not provided with a flow concentrating groove 121a. That is to say, the guide plate 122 mainly plays a flow guiding role, but the effect of concentrating the flow is relatively poor.

The flow guide assembly 12 in Figures 3 to 8 is only provided with one guide plate 122 downstream of the plurality of flow collecting plates 121 along the condensate flow direction, and the guide plate 122 is arranged horizontally. It can be understood that the guide plate 122 is arranged horizontally. The setting position, quantity and setting angle of 122 can be adjusted as needed, for example, the guide plate 122 It can be arranged upstream of multiple flow collecting plates 121 along the condensate flow direction, or between two flow collecting plates 121 . The number of baffles 122 can be multiple, and the baffles 122 can also be arranged at an angle.

When the condensate on the guide plate 122 flows along at least one of the two opposite sides of the guide plate 122 along the air flow direction, it can also come into contact with the hot and humid airflow, and the condensate flowing down from the guide plate 122 can also form water. Therefore, the guide plate 122 can also have better condensation, filtering and chip removal effects.

It can be understood that in some embodiments, only the flow collecting plate 121 may be provided without the flow guide plate 122 .

For example, when the laundry treatment device is a drum-type laundry treatment device, the condensation device 10 may be disposed on the top side of the barrel assembly 20 . When the laundry treatment equipment is a pulsator type laundry treatment equipment, the condensation device 10 can be disposed on any side of the cylinder assembly 20 along the circumferential direction.

The inner cylinder may be a non-porous inner cylinder or a perforated inner cylinder. When the inner cylinder is a perforated inner cylinder, rely on the outer bucket to hold water. When the inner drum is a non-porous inner drum, it relies on the inner drum itself to hold water. That is to say, the inner drum can hold both water and clothes. During the washing process, the water in the inner drum will not enter the outer drum. , during the drainage process, water will be drained through the outer barrel.
