It is to be understood that such directional terms are merely used to facilitate the description of the application and to simplify the description, and are not intended to indicate or imply that the device or element so referred to must be constructed and operated in a particular orientation or orientation, and thus should not be considered as limiting the application.
Referring to fig. 1 to 8, the condensing assembly 10 includes a tube 11 and a flow guiding structure 12.
Referring to fig. 2 to 5, the pipe 11 has a water inlet 11c, a water outlet 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 water outlet 11d, that is, the water inlet 11c of the pipe 11 is located at an upper side of the water outlet 11d, and the condensate flow path formed between the water inlet 11c and the water outlet 11d extends from top to bottom, or condensate flowing into the pipe 11 from the water inlet 11c may flow along the condensate flow path from top to bottom under the action of its own gravity and flow out of the water outlet 11 d. The air inlet 11a and the air outlet 11b form an airflow flow path extending in a transverse direction, that is, the air inlet 11a and the air outlet 11b are respectively located at two opposite sides of the tube 11 in the transverse direction, and the airflow flowing into the tube 11 from the air inlet 11a can flow in the transverse direction of the airflow flow path and flow out from the air outlet 11 b. It should be noted that the airflow flow path described herein only needs to extend in the lateral direction, and is not limited to flow from one designated side to the other designated side. The condensate flow path intersects the gas flow path, i.e. the gas flow path is required to pass through the condensate flow path, i.e. the gas flow passes through the condensate during its flow along the gas flow path.
The specific composition of the condensate is not limited, and may be water or other types of liquids.
The condensation component 10 is used for dehumidifying and cooling the damp and hot airflow, specifically, the damp and hot airflow enters the pipe body 11 from the air inlet 11a and flows along the airflow flow path, the condensate enters the pipe body 11 from the water inlet 11c and flows along the condensate flow path, when the damp and hot airflow passes through the condensate, the damp and hot airflow exchanges heat with the condensate, the condensate absorbs heat of the damp and hot airflow, water vapor in the damp and hot airflow is separated from the airflow due to cooling and is condensed into water drops, the water drops are mixed into the condensate and finally discharged from the water outlet, and thus, the effect of dehumidifying and cooling the damp and hot airflow is achieved, and the gas discharged from the air outlet 11b is relatively low-temperature dry airflow after being cooled and dehumidified. It should be noted that the low-temperature drying air flow is relative to the wet hot air flow, and the temperature of the low-temperature drying air flow is lower than that of the wet hot air flow. The low temperature in the embodiment of the present application may be room temperature.
The condensing assembly 10 of the embodiments of the present application may be used in any suitable application. For example, the embodiment of the present application is described by taking the condensing assembly 10 as an example applied to a laundry treating apparatus.
Referring to fig. 1, an embodiment of the present application provides a clothes treating apparatus including a drum assembly 20, a filtering device 30, an air guiding device 40, and a condensing assembly 10 according to any embodiment of the present application. The drum assembly 20 is provided with a laundry treatment chamber, and an air inlet and an air outlet communicated with the laundry treatment chamber; the filter device 30 is communicated with the air outlet and the air inlet 11 a; the air guide device 40 communicates the air outlet 11b and the air inlet. In the air guide device 40, a fan and a heater are disposed.
Specifically, the airflow channel 11e of the condensation assembly 10 shown in fig. 1 is arranged along the left-right direction of the cylinder assembly 20, that is, most of the area of the airflow channel 11e extends along the left-right direction of the cylinder assembly 20, and in some embodiments, the airflow channel 11e of the condensation assembly 10 may also be arranged along the axial direction of the cylinder assembly 20.
The drain port 11d of the condensation unit 10 shown in fig. 1 is located at the rear side of the cylinder unit 20 in the axial direction, that is, a part of the structure of the condensation unit 10 may extend to the rear side of the cylinder unit 20 in the axial direction to facilitate drainage.
An air flow circulation channel is formed in the clothes treatment equipment, the air guide device 40 guides dry hot air to the clothes treatment cavity through the air inlet, in the clothes treatment cavity, the dry hot air flows through the surface of wet clothes to exchange heat and moisture with the wet clothes to absorb moisture in the clothes and change the dry hot air into wet hot air, thread scraps, impurities and the like generated by the clothes are mixed into the wet hot air in the clothes drying process, the wet hot air flows wrap the thread scraps and the impurities sequentially flow out through the air outlet and then enter the filtering device 30 to be filtered, most of the thread scraps and the impurities can be removed by the filtered wet hot air, however, a small amount of small-size hair scraps can enter the condensing assembly 10 along with the wet hot air from the air inlet 11a, condensate in the condensing assembly 10 is condensed to remove moisture to form wet hot dry air flow, and the low-temperature dry air flow enters the air guide device 40 from the air outlet 11b, the air is heated by a heater in the air guide device 40 to form a drying hot air flow. The drying hot air flow enters the clothes treatment cavity again, and the flocks carried by the wet hot air flow are mixed into the condensate along with the condensed water and are discharged through the water outlet 11d, so that the circulation operation is realized, and the continuous and efficient drying, filtering and scrap removal of the clothes are realized.
Referring to fig. 3-5, the flow directing structure 12 is disposed at the intersection of the condensate flow path and the gas flow path to direct the condensate flowing along the condensate flow path to form a water curtain that can be traversed by the gas flow path, which is equivalent to the water curtain being also simultaneously located on the gas flow path.
Specifically, the condensate may flow through the flow guiding structure 12 in the process of flowing from top to bottom along the condensate flow path, referring to fig. 5, a water curtain may be formed after the condensate flows down from the flow guiding structure 12, and when the wet and hot airflow flowing along the airflow flow path passes through the water curtain, the wet and hot airflow may fully contact the water curtain, that is, the water curtain increases the contact area between the wet and hot airflow and the condensate, so that the wet and hot airflow may fully exchange heat with the condensate, and further the condensation effect may be improved.
In addition, the wet hot air flow can be fully contacted with the water curtain, so the flock entrained in the wet hot air flow is easier to be mixed into the condensate along with the condensed water, and the effect of filtering and removing the flock can be improved.
It should be noted that, the condensation assembly in the related art is generally vertically arranged, and the water inlet, the water outlet, the air inlet and the air outlet are vertically arranged, wherein the air inlet and the water outlet are arranged at a low position, and the air outlet and the water inlet are arranged at a high position, that is, the condensate entering the condensation assembly from the water inlet flows vertically downwards, the damp and hot airflow entering the condensation assembly from the air inlet flows vertically upwards, and the damp and hot airflow passes through the condensate flowing vertically downwards in the process of flowing vertically upwards, so that the condensation effect is achieved. However, the condensing assembly needs a larger condensate fall and a larger airflow flowing distance, so the condensing assembly has a larger volume, more structural limitations and a difficult guarantee of the condensing effect.
The condensate flow path of the condensing assembly 10 of the embodiment of the present application extends downward in the vertical direction, the airflow flow path extends in the transverse direction, and meanwhile, the flow guide structure 12 is disposed at the intersection of the condensate flow path and the airflow flow path, and the flow guide structure 12 can guide the condensate to flow down from the edge of the flow guide structure 12 to form a water curtain through which the hot and humid airflow can pass. Because the airflow flow path of the condensation component 10 extends along the transverse direction, the condensation component 10 does not need a large condensate drop, and does not need a large airflow flow distance in the vertical direction, that is, the condensation component 10 is not affected by the condensate drop and the airflow flow distance, the structure is relatively compact, flexible and changeable, and can adapt to more functional structures, and the condensate can improve the contact area between the wet hot airflow and the condensate by the water curtain formed after flowing down from the edge of the flow guide structure 12, so that the wet hot airflow can perform sufficient heat exchange with the condensate, thereby improving the condensation effect. That is to say, the condensation assembly 10 of the embodiment of the present application is not only relatively compact, but also has a good condensation effect.
For example, referring to fig. 2 and 3, the highest point of the air inlet 11a may be higher than the lowest point of the air outlet 11b, that is, the air inlet 11a has at least a partial region with a higher setting height than the air outlet 11b, and the air inlet 11a shown in fig. 2 and 3 has only a partial region with a higher setting height than the air outlet 11b, which is equivalent to a smaller height difference between the air inlet 11a and the air outlet 11b, which is beneficial to reducing the height dimension of the tube body 11 and saving the installation space of the tube body 11 in the height direction. It should be noted that, when the air inlet 11a is vertically arranged or obliquely arranged as shown in fig. 2 and 3, the air inlet 11a has a distinct highest point and lowest point, and when the air inlet 11a is horizontally arranged (i.e. in the same way as the arrangement of the air outlet 11b shown in fig. 2 and 3), the air inlet 11a has only one arrangement height, which is equal to the arrangement height of the highest point of the air inlet 11 a. Similarly, when the outlet 11b is vertically or obliquely arranged, the outlet 11b has obvious highest point and lowest point, and when the outlet 11b is horizontally arranged as shown in fig. 2 and 3, the outlet 11b has only one set height, which is equal to the set height of the lowest point of the outlet 11 b.
In some embodiments, the highest point of the air inlet 11a may be set to a height equal to the lowest point of the air outlet 11b, or the highest point of the air inlet 11a may be set to a height lower than the lowest point of the air outlet 11 b.
The position that sets up of water inlet 11c of this application embodiment can be adjusted as required, and more preferably, please refer to fig. 2 to fig. 4, and water inlet 11c can set up on the roof of body 11, is provided with the inlet tube on the roof of body 11 in fig. 2 to fig. 4, and the entry of inlet tube is exactly water inlet 11c, in some embodiments, also can be the water inlet 11c that forms the roof of running through on the roof.
The relative height between the water inlet 11c and the air outlet 11b can also be adjusted according to the requirement, for example, referring to fig. 2 to 4, the highest point of the water inlet 11c can be set higher than the lowest point of the air outlet 11b, that is, the water inlet 11c is set higher than the air outlet 11b in at least a partial region. It should be noted that the definition of the highest point of the water inlet 11c is the same as that of the highest point of the air inlet 11 a. The water inlet 11c and the air outlet 11b shown in fig. 2 to 4 are both horizontally disposed, and although the whole water inlet 11c is disposed at a height higher than that of the air outlet 11b, the height difference between the water inlet 11c and the air outlet 11b is relatively small, so that the height dimension of the pipe body 11 is also reduced, and the installation space of the pipe body 11 in the height direction is saved.
In some embodiments, the highest point of the water inlet 11c may be set to be equal to the lowest point of the air outlet 11b, or the highest point of the water inlet 11c may be set to be lower than the lowest point of the air outlet 11 b.
In one embodiment, referring to fig. 3 to 5, the tube 11 may form an airflow channel 11e having an air inlet 11a and an air outlet 11b, that is, the airflow path is located in the airflow channel 11e, the water inlet 11c may be located at an upper side of the airflow channel 11e, the water outlet 11d may be located at a lower side of the airflow channel 11e, a height of the water outlet 11d relative to the water inlet 11c is higher than a height of the airflow channel 11e, and a height of the water outlet 11d is lower than the height of the airflow channel 11 e.
In one embodiment, referring to fig. 3, a partition 11f may be disposed in the tube 11, the partition 11f dividing the tube 11 into an air flow channel 11e and a drain channel 11g located at the lower side of the air flow channel 11e, wherein the drain channel 11g has a drain 11d, that is, a part of the condensate flow path passes through the drain channel 11 g. Part of the edge of the partition wall 11f in fig. 3 is spaced apart from the inner wall of the pipe body 11 so that a water passing opening (not shown) communicating the air flow path and the drainage passage 11g is formed at the space, and in some embodiments, the water passing opening may be formed directly on the partition wall 11 f. After passing through the airflow flow path, the condensate flows from the drain port into the drain passage 11g and is discharged from the drain port 11 d. The drain passage 11g may serve to collect the condensate so as to discharge the condensate from the drain port 11d in time.
In addition, referring to fig. 4 and 5, the flow guiding structure 12 may be located downstream of the water gap along the flow direction of the air flow, which is equivalent to that the hot and humid air flows first through the water gap and then through the condensate. The partial area of the partition wall 11f facing one side of the flow guiding structure 12 may form a flow guiding surface 11h, the flow guiding surface 11h guides a flow path of the condensate to extend to the water passing opening, the flow guiding surface 11h in fig. 4 and 5 is a curved surface, in some embodiments, the flow guiding surface 11h may also be an inclined plane, the condensate flowing through the flow guiding structure 12 may flow to the water passing opening along the flow guiding surface 11h after falling to the flow guiding surface 11h, which is equivalent to the flow direction of the condensate flowing along the flow guiding surface 11h being 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 drying air flow as much as possible.
In one embodiment, referring to fig. 2 and 3, the airflow channel 11e may also have a first extension 11e1 and a second extension 11e 2; the second extension section 11e2 is communicated with the first extension section 11e1 and extends to one side of the first extension section 11e1, that is, a certain included angle is formed between the second extension section 11e2 and the first extension section 11e1, an air inlet 11a is formed at one end of the first extension section 11e1 far away from the second extension section 11e2, an air outlet 11b is formed at one end of the second extension section 11e2 far away from the first extension section 11e1, and the condensate flow path passes through the first extension section 11e 1.
Specifically, for convenience of description, it is considered that the first extension 11e1 extends along the length direction of the tube 11, the second extension 11e2 extends along the width direction of the tube 11, and the second extension 11e2 is provided to save the length of the tube 11, so that the overall structure of the condensing unit 10 can be more compact. In addition, a small amount of fine droplets formed by condensate may be entrained in the low-temperature drying airflow formed after condensation, and therefore, by providing the first extension 11e1 and the second extension 11e2, a corner may be formed at the connection between the first extension 11e1 and the second extension 11e2, and when the low-temperature drying airflow passes through the connection between the first extension 11e1 and the second extension 11e2, the fine droplets entrained in the low-temperature drying airflow may be thrown onto the side wall of the airflow channel 11e by the centrifugal force, and thus, the condensate may be prevented from flowing to the air outlet 11b along with the airflow as much as possible.
The structure of the flow guiding structure 12 may be various, for example, referring to fig. 3 to 8, the flow guiding structure 12 includes a flow guiding plate 121, the flow guiding structure 12 shown in fig. 3 to 8 is provided with a plurality of flow guiding plates 121, each flow guiding plate 121 is arranged at intervals, in some embodiments, the flow guiding structure 12 may also be provided with only one flow guiding plate 121, the shape of the flow guiding plate 121 shown in fig. 3 to 8 is substantially rectangular, it is understood that the shape of the flow guiding plate 121 is not limited to rectangular, and in some embodiments, the shape of the flow guiding plate 121 may also be circular, oval, trapezoid, triangle, special-shaped, and the like. The baffle 121 may direct the condensate to flow to opposite sides of the baffle 121 in the direction of flow of the air stream. It should be noted that the airflow direction refers to a direction in which the airflow flows along the airflow path. That is, after the condensate flows down from the two opposite sides of the flow guiding plate 121 along the flowing direction of the air flow, the condensate may form a water curtain on the two opposite sides of the flow guiding plate 121 along the flowing direction of the air flow, and the flow guiding plate 121 may also guide the condensate to flow only on one of the two opposite sides of the flow guiding plate 121 along the flowing direction of the air flow, which corresponds to that the condensate flows down from one of the two opposite sides of the flow guiding plate 121 along the flowing direction of the air flow, and then only the condensate flows down on the side where the condensate flows down. For example, with continued reference to fig. 3-5, four baffles 121 are shown in fig. 3-5, and for ease of description, the four baffles 121 shown in fig. 3-5 are referred to as a first baffle 121a, a second baffle 121b, a third baffle 121c, and a fourth baffle 121d, wherein, the first guide plate 121a, the second guide plate 121b, and the third guide plate 121c can guide the condensate to flow to the two opposite sides of the guide plate 121 along the airflow flowing direction, the condensate flowing down from the first guide plate 121a, the second guide plate 121b, and the third guide plate 121c forms water curtains on the two opposite sides of the first guide plate 121a, the second guide plate 121b, and the third guide plate 121c along the airflow flowing direction, the fourth baffle 121d guides the condensate to one of two opposite sides of the baffle 121 in the flowing direction of the air stream, and the condensate flowing down the fourth baffle 121d forms a water curtain only on the side where the condensate flows down. The guide plate 121 guides the condensate to flow to the guide plate 121 along the opposite sides of the air flow flowing direction, so that the wet hot air can pass through at least two water curtains, and therefore, the wet hot air can be more fully contacted with the water curtains, and the condensing and filtering scrap removing effects can be further improved.
It should be noted that the diversion structure 12 shown in fig. 3 to 5 is actually a part of the diversion plates 121 of the plurality of diversion plates 121 guiding the condensate to flow to two opposite sides of the diversion plate 121 in the airflow flowing direction, and another part of the diversion plates 121 guiding the condensate to flow to one of the two opposite sides of the diversion plate 121 in the airflow flowing direction, and it is understood that, in some embodiments, when the diversion structure 12 has a plurality of diversion plates 121, each diversion plate 121 may also guide the condensate to flow to two opposite sides of the diversion plate 121 in the airflow flowing direction, and each diversion plate 121 may also guide the condensate to flow to one of the two opposite sides of the diversion plate 121 in the airflow flowing direction. When the flow directing structure 12 has only one flow deflector 121, the flow deflector 121 may be configured to direct condensate to flow either on opposite sides of the flow deflector 121 in the direction of flow of the gas stream, or on one of the opposite sides of the flow deflector 121 in the direction of flow of the gas stream.
Referring to fig. 4 and 5, the flow guiding surface of the flow guiding plate 121 may be inclined downward from the downstream side of the flow direction of the air flow to the upstream side of the flow direction of the air flow, that is, the hot and humid air flow may contact with the condensate on the flow guiding surface in addition to the water curtain, so that the contact area between the hot and humid air flow and the condensate may also be increased to further improve the condensation, filtration and dust removal effects.
It will be appreciated that the flow guide surface is not limited to being disposed obliquely downward from a side downstream in the direction of flow of the airflow toward a side upstream in the direction of flow of the airflow, and for example, in some embodiments, the flow guide surface may be disposed horizontally.
In addition, the flow guiding surface shown in fig. 4 and 5 is a flow guiding plane, and in some embodiments, the flow guiding surface may also be a curved surface, which is equivalent to the flow guiding surface that may also collect a portion of the condensate.
The relative position between the flow guide plate 121 and the water inlet 11c can be determined as required, as long as the condensate flowing into the pipe 11 from the water inlet 11c can flow onto the flow guide plate 121, for example, referring to fig. 4, the relative position between the flow guide plate 121 and the water inlet 11c can be: the axial center line of the water inlet 11c passes through the baffle 121, that is, the arrangement of the first baffle 121a, the second baffle 121b and the third baffle 121c in fig. 4, the relative position of the baffle 121 and the water inlet 11c may also be: the baffle 121 is located on one of two opposite sides of the axial center line of the water inlet 11c along the flowing direction of the air flow, that is, the fourth baffle 121d in fig. 4 is arranged.
The plurality of baffles 121 may be disposed at intervals in the pipe 11, for example, referring to fig. 4 to 7, each baffle 121 may be disposed in a vertically layered manner, that is, each baffle 121 may be sequentially disposed at intervals in a vertical direction, so as to form a multilayer structure.
Further, referring to fig. 4 to 7, for the baffles 121 of the multi-layer structure, the relative positions of at least some vertically adjacent baffles 121 may satisfy: in the condensate flow direction, the downstream baffle 121 can receive at least part of the condensate flowing down from the upstream baffle 121, that is, at least two vertically adjacent baffles 121 are positioned in such a way that at least part of the condensate flowing down from one baffle 121 can flow down to another baffle 121 that is adjacent to the lower side of the baffle 121.
Specifically, taking the first guide plate 121a and the second guide plate 121b in fig. 4 as an example, the first guide plate 121a and the second guide plate 121b are disposed adjacent to each other in the vertical direction, the first guide plate 121a is located upstream of the second guide plate 121b in the flow direction of the condensate, the horizontal projection of the first guide plate 121a is located in the horizontal projection area of the second guide plate 121b, and it should be noted that the horizontal projection refers to a projection on a horizontal plane perpendicular to the vertical direction. That is, the condensate on the first baffle 121a may flow from the opposite sides of the first baffle 121a along the airflow flowing direction to the second baffle 121b, which is equivalent to the condensate flowing down from the first baffle 121a flowing to the second baffle 121b, similarly, the second baffle 121b and the third baffle 121c are vertically adjacent to each other, the second baffle 121b is located upstream of the third baffle 121c along the condensate flowing direction, the horizontal projection of the second baffle 121b is located in the horizontal projection area of the third baffle 121c, and the condensate flowing down from the second baffle 121b flowing to the third baffle 121 c. Referring to fig. 4, the third baffle 121c and the fourth baffle 121d are disposed vertically adjacent to each other, and the third baffle 121c is located upstream of the fourth baffle 121d along the flow direction of the condensate, and only one of the two opposite sides of the third baffle 121c along the flow direction of the air flow has a horizontal projection located in the horizontal projection area of the fourth baffle 121d, so that only a part of the condensate flowing down from the third baffle 121c flows onto the fourth baffle 121d, and the other part of the condensate flows directly to the drain 11d without passing through the fourth baffle 121d, or only a part of the condensate flowing down from the third baffle 121c flows onto the fourth baffle 121 d.
It should be noted that the first baffle 121a, the second baffle 121b and the third baffle 121c are not limited to the arrangement shown in fig. 4, for example, in another embodiment, referring to fig. 6, for convenience of description, two opposite sides of the baffle 121 in the airflow flowing direction may be referred to as a first side and a second side, respectively, the first side in fig. 6 is located upstream of the second side in the airflow flowing direction, and in some embodiments, the first side may be located downstream of the second side in the airflow flowing direction, and the positions corresponding to the first side and the second side may be interchanged. In fig. 6, the horizontal projection of the first side of the first baffle 121a is located in the horizontal projection area of the second baffle 121b, the horizontal projection of the second side of the first baffle 121a and the horizontal projection of the second side of the second baffle 121b are both located in the horizontal projection area of the third baffle 121c, which is equivalent to the condensate flowing down from the first side of the first baffle 121a flowing onto the second baffle 121b, the condensate flowing down from the second side of the first baffle 121a and the second side of the second baffle 121b flowing down onto the third baffle 121c, and the condensate flowing down from the first side of the second baffle 121b not flowing onto the third baffle 121c, that is, the baffle 121 located downstream in the flow direction of the condensate may receive a portion of the condensate flowing down from the adjacent and upstream baffle 121.
In the diversion structure 12 shown in fig. 4 and 6, each of the downstream baffles 121 may receive at least part of the condensate flowing down the adjacent and upstream baffles 121, and in another embodiment, referring to fig. 7, the relative positions of the first baffle 121a, the second baffle 121b, and the third baffle 121c may also be: the horizontal projection of the first side of the first guide plate 121a is located in the horizontal projection area of the second guide plate 121b, the horizontal projection of the second side of the first guide plate 121a is located in the horizontal projection area of the third guide plate 121c, and the horizontal projection of the second side of the second guide plate 121b is offset from the horizontal projection of the first side of the third guide plate 121c, that is, the condensate flowing down from the first side of the first guide plate 121a flows onto the second guide plate 121b, and the condensate flowing down from the second side of the first guide plate 121a flows onto the third guide plate 121c, but the condensate flowing down from the second side of the second guide plate 121b does not flow onto the third guide plate 121c but continues to flow down avoiding the third guide plate 121c, that is, the second guide plate 121b can contain the part of the condensate flowing down on the first guide plate 121a which is adjacent and located upstream, however, the third baffle 121c does not receive the condensate flowing down from the adjacent and upstream second baffle 121b, and in other words, in the plurality of baffles 121, only the relative positions of some vertically adjacent baffles 121 satisfy: in the direction of condensate flow, the downstream baffle 121 may receive at least a portion of the condensate flowing down the upstream baffle 121.
The guide plate 121 located at the downstream of the flowing direction of the condensate liquid is connected with at least part of the condensate liquid flowing down on the adjacent guide plate 121 located at the upstream, so that a water curtain can be formed between the two adjacent guide plates 121, the flow speed of the condensate liquid can be reduced, and the condensation, filtration and chip removal effects can be further improved. Particularly, when at least some of the baffles 121 of the plurality of baffles 121 can also guide the condensate to flow to the opposite sides of the baffles 121 along the flowing direction of the airflow, the condensing and filtering effects of the condensing assembly 10 can be greatly improved.
In addition, referring to fig. 7, although the third baffle 121c in fig. 7 does not receive the condensate flowing down from the second baffle 121b located adjacent and upstream, the condensate flowing down from the second side of the second baffle 121b also forms a single water curtain, that is, compared with the diversion structure 12 shown in fig. 4, the diversion structure 12 shown in fig. 4 increases the number of the water curtains below the third baffle 121c, thereby improving the condensation, filtration and debris removal effects of the condensation assembly 10.
In another embodiment, referring to fig. 8, the flow guiding structure 12 may also be a multi-layer structure in which only one flow guide plate 121 is disposed in each layer, and in the flow guiding structure 12 shown in fig. 3 to 7, some flow guide plates 121 of the plurality of flow guide plates 121 are disposed in a vertically layered manner, and some flow guide plates 121 are disposed in a laterally spaced manner, that is, the flow guiding structure 12 shown in fig. 8 also employs a multi-layer structure, but compared with the flow guiding structure 12 shown in fig. 3 to 7, at least one layer of the flow guiding structure 12 shown in fig. 8 may be disposed with at least two flow guide plates 121, and at least two flow guide plates 121 of the same layer are disposed in a laterally spaced manner. It should be noted that the diversion structure 12 shown in fig. 8 may adopt the diversion plate 121 described in any of the foregoing embodiments, and details are not described here.

When the laundry treating apparatus is a pulsator type laundry treating apparatus, the condensing unit 10 may be disposed at any one side of the drum unit 20 in a circumferential direction.
Wherein, the inner cylinder can be a non-hole inner cylinder or a hole inner cylinder. When the inner cylinder is a porous inner cylinder, water is contained by the outer cylinder. When the inner barrel is a non-hole type inner barrel, water can be contained in the inner barrel, namely, the inner barrel can contain water and clothes, the water in the inner barrel cannot enter the outer barrel in the washing process, and the water can be drained through the outer barrel in the drainage process.
