Referring to fig. 1 to 4, a condenser 10 according to an embodiment of the present application is provided, wherein the condenser 10 includes a condenser tube 11, and the condenser tube 11 has an air inlet 11a, an air outlet 11b, a water inlet 11c and a water outlet 11d.

An air flow channel 11e extending in the transverse direction is formed between the air inlet 11a and the air outlet 11b, that is, the air inlet 11a and the air outlet 11b are respectively located at two opposite transverse sides of the condensation duct 11, and the air flow flowing into the condensation duct 11 from the air inlet 11a can flow in the transverse direction along the air flow channel 11e and flow out from the air outlet 11b, that is, the path in the air flow channel 11e is the air flow path. The air flow channel 11e described herein need only extend in the lateral direction, and is not limited to a direction from one specific side to the other specific side.

The water inlet 11c is located at the upper side of the air flow passage 11e, and the water outlet 11d is located at the lower side of the air flow passage 11e, that is, the water inlet 11c is located at a higher level than the air flow passage 11e, and the water outlet 11d is located at a lower level than the air flow passage 11 e. A condensate flow path is formed between the water inlet 11c and the water outlet 11d through the air flow channel 11e, that is, the water inlet 11c of the condensation duct 11 is located at the upper side of the water outlet 11d, the condensate flow path formed between the water inlet 11c and the water outlet 11d extends from top to bottom, condensate flowing into the condensation duct 11 from the water inlet 11c falls down from the upper side of the air flow channel 11e by self gravity, passes through the air flow channel 11e during the falling, and finally flows out from the water outlet 11d.

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

The condenser 10 is used for dehumidifying and cooling the hot and humid air flow, specifically, the hot and humid air flow enters the condenser pipe 11 from the air inlet 11a and flows along the air flow channel 11e, the condensate enters the condenser pipe 11 from the water inlet 11c and flows along the condensate flow path, when the hot and humid air flow passes through the condensate, the hot and humid air flow exchanges heat with the condensate, the condensate absorbs heat of the hot and humid air flow, water vapor in the hot and humid air flow is separated from the air flow due to cooling and is condensed into water drops, the water drops are mixed into the condensate, and finally the water drops are discharged from the water outlet, so that the effect of dehumidifying and cooling the hot and humid air flow is achieved, and the air discharged from the air outlet 11b is relatively low-temperature dry air flow after cooling and dehumidification. The low temperature dry air flow is a relatively wet and hot air flow, and the temperature of the low temperature dry air flow is lower than that of the wet and hot air flow. The low temperature in the embodiments of the present application may be room temperature.

The condenser 10 of the present embodiment may be used in any suitable application. Illustratively, the embodiment of the present application will be described with reference to the application of the condenser 10 to a laundry treating apparatus.

Referring to fig. 1, an embodiment of the present application provides a laundry treating apparatus including a drum assembly 20, a filtering device 30, an air guiding device 40, and a condenser 10 according to any one of the embodiments of the present application. The condenser 10 is arranged at the top of the cylinder assembly 20, and the cylinder assembly 20 is provided with a clothes treatment cavity, and an air inlet and an air outlet communicated with the clothes treatment cavity; the filtering device 30 is communicated with the air outlet and the air inlet 11a; the air guide 40 communicates with the air outlet 11b and the air inlet. The blower and the heater are disposed in the air guide device 40.

Specifically, the airflow channels 11e of the condenser 10 shown in fig. 1 are arranged in the left-right direction of the cylinder assembly 20, that is, most of the area of the airflow channels 11e extends in the left-right direction of the cylinder assembly 20, and in some embodiments, the airflow channels 11e of the condenser 10 may also be arranged in the axial direction of the cylinder assembly 20.

The drain port 11d of the condenser 10 shown in fig. 1 is located at the rear side of the bowl assembly 20 in the axial direction, that is, a part of the structure of the condenser 10 may be extended to the rear side of the bowl assembly 20 in the axial direction to facilitate drainage.

The clothes treatment device is internally provided with an air flow circulation channel, the air guide device 40 guides the hot dry air to the clothes treatment cavity through the air inlet, the hot dry air flows through the surface of wet clothes in the clothes treatment cavity, the hot dry air exchanges heat with the wet clothes, moisture in the clothes is absorbed and becomes hot wet air, the filings, impurities and the like generated by the clothes in the clothes drying process are mixed into the hot wet air, the hot wet air is wrapped with the filings and the impurities, flows out of the air outlet in sequence and then enters the filtering device 30 for filtering, most filings and impurities can be removed by the hot wet air after filtering, but a small amount of filings with smaller size can enter the condenser 10 along with the hot wet air, the hot wet air forms a low-temperature dry air flow after condensation and dehumidification in the condenser 10, and the low-temperature dry air flows into the air guide device 40 from the air outlet 11b and forms a hot dry air flow after being heated by the heater in the air guide device 40. The drying hot air flow enters the clothes treatment cavity again, and the filth wrapped in the wet hot air flow is mixed with the condensed water into condensate and is discharged through the water outlet 11d, so that the circulation operation is realized, and the continuous and efficient drying of clothes and the filth removal by filtration are realized.

The condensers in the related art are generally vertically arranged, the water inlet, the water outlet, the air inlet and the air outlet are all vertically arranged, wherein the air inlet and the water outlet are arranged at the lower part, the air outlet and the water inlet are arranged at the upper part, that is, condensate entering the condenser from the water inlet flows downwards vertically, and damp and hot air flow entering the condenser from the air inlet flows upwards vertically, and the damp and hot air flow passes through the condensate flowing downwards vertically in the process of flowing upwards vertically, so that the condensation effect is achieved. However, since such a condenser requires a large condensate head and a large air flow distance, the condenser has a relatively large volume, occupies a large installation space, and has a large structural limitation, and it is difficult to install a special filter device in the condenser, particularly when the special filter device is required.

The air flow channel 11e of the condenser 10 according to the embodiment of the present application extends transversely, the water inlet 11c is located at the upper side of the air flow channel 11e, the water outlet 11d is located at the lower side of the air flow channel 11e, the condensate flow path formed between the water inlet 11c and the water outlet 11d passes through the air flow channel 11e from top to bottom, and the condensate flowing along the condensate flow path flows downwards under the action of gravity and exchanges heat with the hot and humid air flowing along the air flow channel 11e when passing through the air flow channel 11 e. Since the airflow channel 11e of the condenser 10 extends in the lateral direction, the condenser 10 does not need a large airflow distance in the vertical direction and a large condensate drop, that is, the condenser 10 is not affected by the condensate drop and the airflow distance, and the structure is relatively compact, flexible and changeable, and can adapt to more functional structures, particularly to some special filtering devices 30.

The relative height between the air inlet 11a and the air outlet 11b in the embodiment of the present application may be adjusted according to needs, 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, at least a part of the air inlet 11a is higher than the air outlet 11b, and only a part of the air inlet 11a shown in fig. 2 and 3 is higher than the air outlet 11b, which is equivalent to a smaller height difference between the air inlet 11a and the air outlet 11b, so that the height dimension of the condenser tube 11 is reduced, and the installation space of the condenser tube 11 in the height direction is saved. It should be noted that, when the air inlet 11a is vertically disposed or is obliquely disposed as shown in fig. 2 and 3, the air inlet 11a has a distinct highest point and a lowest point, and when the air inlet 11a is horizontally disposed (i.e., in the same manner as the air outlet 11b shown in fig. 2 and 3), the air inlet 11a has only one disposed height, which is equal to the disposed height of the highest point of the air inlet 11 a. Similarly, when the air outlet 11b is vertically or obliquely arranged, the air outlet 11b has a distinct highest point and lowest point, and when the air outlet 11b is horizontally arranged as shown in fig. 2 and 3, the air outlet 11b has only one set height, which 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 height of the lowest point of the air outlet 11b.

The position of the water inlet 11c in the embodiment of the present application may be adjusted according to needs, and preferably, referring to fig. 2 to 4, the water inlet 11c may be disposed on the top wall of the condensation tube 11, and in fig. 2 to 4, a water inlet pipe is disposed on the top wall of the condensation tube 11, and the inlet of the water inlet pipe is the water inlet 11c, and in some embodiments, the water inlet 11c penetrating the top wall may also be formed on the top wall.

The relative height between the water inlet 11c and the air outlet 11b may also be adjusted according to the need, for example, referring to fig. 2 to 4, the highest point of the water inlet 11c may be higher than the lowest point of the air outlet 11b, that is, at least a part of the water inlet 11c is higher than the air outlet 11b. 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 11 a. The water inlet 11c and the air outlet 11b shown in fig. 2 to 4 are both horizontally arranged, and although the whole water inlet 11c is arranged at a higher height than the air outlet 11b, the height difference between the water inlet 11c and the air outlet 11b is also relatively small, so that the height dimension of the condensation duct 11 is also reduced, and the installation space of the condensation duct 11 in the height direction is saved.

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

In one embodiment, referring to fig. 3, the condenser tube 11 has a partition wall 11f therein, and the partition wall 11f divides the air flow channel 11e and a drain channel 11g located at the lower side of the air flow channel 11e in the condenser tube 11. The drain passage 11g has a drain port 11d, that is, a part of the condensate flow path passes through the drain passage 11g. Part of the edge of the partition wall 11f in fig. 3 is spaced apart from the inner wall of the condensation duct 11 so that a water passing port (not shown) communicating the air flow passage 11e and the drain passage 11g is formed at the space, and in some embodiments, the water passing port may be formed directly on the partition wall 11 f. After the condensate passes through the air flow passage 11e, the condensate flows into the drain passage 11g from the water passing port, and is discharged from the drain port 11d. The drain channel 11g may function to collect condensate so as to drain condensate from the drain port 11d in time.

In addition, referring to fig. 4, the region of the condensate flow path passing through the airflow channel 11e may be located downstream of the water gap in the airflow direction, which is equivalent to that the hot and humid airflow passes over the water gap before passing through the condensate. The partial area of the partition wall 11f facing the air flow channel 11e forms a drainage surface 11h, the drainage surface 11h guides the condensate flow path to extend towards the water passing port, the drainage surface 11h of fig. 4 is a curved surface, in some embodiments, the drainage surface 11h may also be an inclined plane, after condensate passing through the air flow channel 11e falls on the drainage surface 11h, the condensate may flow along the drainage surface 11h towards the water passing port, which corresponds to the flow direction of the condensate flowing along the drainage surface 11h opposite to the flow direction of the air flow, thereby preventing the condensate from flowing along with the condensed low-temperature drying air flow towards the air outlet 11b 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 11e2; the second extension segment 11e2 is communicated with the first extension segment 11e1 and extends to one side of the first extension segment 11e1, that is, a certain included angle is formed between the second extension segment 11e2 and the first extension segment 11e1, an air inlet 11a is formed at one end, away from the second extension segment 11e2, of the first extension segment 11e1, an air outlet 11b is formed at one end, away from the first extension segment 11e1, of the second extension segment 11e2, and a condensate flow path penetrates through the first extension segment 11e1.

Specifically, for convenience of description, it may be considered that the first extension 11e1 extends along the length direction of the condensation duct 11, the second extension 11e2 extends along the width direction of the condensation duct 11, and providing the second extension 11e2 corresponds to saving the length of the condensation duct 11, so that the overall structure of the condenser 10 can be more compact. In addition, a small amount of tiny droplets formed by condensate may be mixed in the low-temperature drying air flow formed after condensation, so that by arranging the first extension section 11e1 and the second extension section 11e2, a corner can be formed at the communication position of the first extension section 11e1 and the second extension section 11e2, and when the low-temperature drying air flow passes through the communication position of the first extension section 11e1 and the second extension section 11e2, the tiny droplets mixed in the low-temperature drying air flow can be thrown onto the side wall of the air flow channel 11e under the action of centrifugal force, thereby preventing the condensate from flowing along with the air flow to the air outlet 11b as much as possible.

In an embodiment, referring to fig. 5 to 11, the condenser 10 further includes a flow guiding assembly 12, the flow guiding assembly 12 is disposed in the airflow channel 11e and is located on the condensate flow path, and when the condensate flows through the flow guiding assembly 12, the flow guiding assembly 12 can guide the condensate so that the hot and humid airflow can fully contact with the condensate, and further the condensation and the dust filtering effects of the condenser 10 can be improved.

The flow guide assembly 12 may have various structural forms, and as an example, referring to fig. 5 to 11, the flow guide assembly 12 includes a flow guide plate 121, and the flow guide plate 121 guides condensate to flow to at least one of two opposite sides of the flow guide plate 121 along the flow direction of the air flow.

Specifically, the baffle assembly 12 shown in fig. 5 to 11 is provided with a plurality of baffles 121, where each baffle 121 is disposed at intervals, in some embodiments, the baffle assembly 12 may be provided with only one baffle 121, and the shape of the baffle 121 shown in fig. 5 to 11 is substantially rectangular, it is understood that the shape of the baffle 121 is not limited to rectangular, and in some embodiments, the shape of the baffle 121 may be circular, oval, trapezoidal, triangular, or shaped. The baffle 121 may direct condensate to opposite sides of the baffle 121 in the direction of airflow. The airflow direction refers to a direction along which the airflow flows along the airflow path. That is, after condensate flows down from opposite sides of the baffle 121 in the flow direction of the air flow, water curtains may be formed at the opposite sides of the baffle 121 in the flow direction of the air flow, respectively. The deflector 121 may guide the condensate to flow only to one of the opposite sides of the deflector 121 in the direction of flow of the air flow, which corresponds to the formation of a water curtain only on the side where the condensate flows down after the condensate flows down from one of the opposite sides of the deflector 121 in the direction of flow of the air flow. For example, referring to fig. 5 to 7, four baffles 121 are shown in fig. 5 to 7, for convenience of description, the four baffles 121 shown in fig. 5 to 7 are referred to as a first baffle 121a, a second baffle 121b, a third baffle 121c and a fourth baffle 121d, respectively, wherein the first baffle 121a, the second baffle 121b and the third baffle 121c may guide condensate to flow toward opposite sides of the baffle 121 in the airflow direction, and condensate flowing down from the first baffle 121a, the second baffle 121b and the third baffle 121c forms water curtains on opposite sides of the first baffle 121a, the second baffle 121b and the third baffle 121c in the airflow direction, respectively, while the fourth baffle 121d guides condensate to flow toward one of the opposite sides of the baffle 121 in the airflow direction, and condensate flowing down from the fourth baffle 121d forms water curtains only on one side of condensate flowing down. The water curtain can improve the contact area of the damp and hot air flow and the condensate so that the damp and hot air flow can fully exchange heat with the condensate, and therefore, the condensing effect can be improved. In addition, when the guide plate 121 guides the condensate to flow to the opposite sides of the guide plate 121 in the air flow direction, the hot and humid air flow can be made to pass through at least two water curtains, that is, compared with the guide plate 121 guides the condensate to flow to one of the opposite sides of the guide plate 121 in the air flow direction, the guide plate 121 guides the condensate to flow to the opposite sides of the guide plate 121 in the air flow direction, the number of water curtains can be increased so that the hot and humid air flow can be more sufficiently contacted with the water curtains, whereby the condensation, filtering and dust removing effects can be further improved.

It should be noted that, in the flow guide assembly 12 shown in fig. 5 to 7, a part of the flow guide plates 121 of the plurality of flow guide plates 121 guide the condensate to flow to opposite sides of the flow guide plates 121 in the airflow direction, and another part of the flow guide plates 121 guide the condensate to flow to one of opposite sides of the flow guide plates 121 in the airflow direction, it may be understood that, in some embodiments, when the flow guide assembly 12 has the plurality of flow guide plates 121, each of the flow guide plates 121 guide the condensate to flow to opposite sides of the flow guide plates 121 in the airflow direction, and also each of the flow guide plates 121 guide the condensate to flow to one of opposite sides of the flow guide plates 121 in the airflow direction. When the deflector assembly 12 has only one deflector 121, the deflector 121 may be configured to direct condensate to flow to opposite sides of the deflector 121 in the direction of airflow, or may be configured to direct condensate to flow to one of opposite sides of the deflector 121 in the direction of airflow.

Referring to fig. 6 and 7, the guiding surface of the guiding plate 121 may be disposed obliquely downward from the downstream side in the airflow direction to the upstream side in the airflow direction, that is, the hot and humid airflow may contact with condensate on the guiding surface in addition to the water curtain, thereby increasing the contact area between the hot and humid airflow and the condensate to further improve the condensation and filtering and chip removing effects.

It will be appreciated that the flow directing surface is not limited to being disposed obliquely downward from the side downstream in the direction of flow of the air flow to the side upstream in the direction of flow of the air flow, for example, in some embodiments, the flow directing surface may be disposed horizontally.

In an embodiment, referring to fig. 8, a condensation groove 121e may be formed on the flow guiding plate 121, where the condensation groove 121e may collect condensate, so that not only the flow rate of the condensate may be slowed down, but also a portion of the hot and humid air flowing along the air flow path may be fully contacted with the condensate in the condensation groove 121e, so that condensation and filtering and chip removing effects may be improved.

The flow-gathering groove 121e may be formed in various ways, for example, referring to fig. 8, the flow-guiding surface of the flow-guiding plate 121 may define the flow-gathering groove 121e, that is, a non-planar flow-guiding surface may be used to form the flow-gathering groove 121e, for example, the flow-guiding surface may be formed by bending the flow-guiding plate 121 to form the flow-gathering groove 121e. Specifically, the flow guiding surface of the flow guiding plate 121 shown in fig. 8 is a curved surface curved towards the bottom end surface near the flow guiding plate 121, in some embodiments, the flow guiding surface may also include a first inclined surface and a second inclined surface that are connected to each other, and the first inclined surface and the second inclined surface may be both inclined planes, or one of them may be inclined planes, and the other one is an inclined curved surface, where a converging groove 121e is defined between the first inclined surface and the second inclined surface.

In some embodiments, a part of the top area of the baffle 121 may be recessed to form a converging groove 121e.

In the flow guiding assembly 12 shown in fig. 8, three flow guiding plates 121 are provided with the flow gathering groove 121e, and the last flow guiding plate 121 along the flowing direction of condensate is not provided with the flow gathering groove 121e, it is understood that the setting positions, the number and the like of the flow guiding plates 121 without the flow gathering groove 121e can be adjusted according to requirements, in some embodiments, all flow guiding plates 121 may be provided with the flow gathering groove 121e, and all flow guiding plates 121 may not be provided with the flow gathering groove 121e.

The relative positions of the baffle 121 and the water inlet 11c may be determined according to needs, as long as condensate flowing into the condensation duct 11 from the water inlet 11c can flow onto the baffle 121, and referring to fig. 6, for example, the relative positions of the baffle 121 and the water inlet 11c may be: the axial center line of the water inlet 11c passes through the baffle 121, that is, the first baffle 121a, the second baffle 121b and the third baffle 121c in fig. 6 are arranged in the manner that the relative positions of the baffle 121 and the water inlet 11c may be: the baffle 121 is disposed on one of opposite sides of the axial center line of the water inlet 11c in the direction of flow of the air stream, i.e., the fourth baffle 121d in fig. 6.

There are various ways in which the plurality of baffles 121 are disposed at intervals in the condensation duct 11, and as an example, referring to fig. 5 to 7, each of the baffles 121 may be disposed vertically in layers, that is, each of the baffles 121 may be disposed vertically in sequence at intervals to form a multi-layered structure.

Further, referring to fig. 6 to 11, for the baffle 121 with a multi-layer structure, the relative positions of at least part of vertically adjacent baffles 121 may satisfy: in the direction of flow of condensate, the downstream deflector 121 may receive at least part of the condensate flowing down from the upstream deflector 121, i.e. at least two vertically adjacent deflectors 121 are positioned such that at least part of the condensate flowing down from one deflector 121 may flow down to another deflector 121 located on the underside of the deflector 121 and adjacent thereto.

Specifically, taking the first deflector 121a and the second deflector 121b in fig. 6 and 7 as an example, the first deflector 121a and the second deflector 121b are disposed adjacent to each other in the vertical direction, and the first deflector 121a is located upstream of the second deflector 121b in the condensate flow direction, and the horizontal projection of the first deflector 121a is located in the horizontal projection area of the second deflector 121b, and it should be noted that the horizontal projection refers to the projection on the horizontal plane perpendicular to the vertical direction. That is, the condensate on the first baffle 121a may flow onto the second baffle 121b from opposite sides of the first baffle 121a in the direction of flow of the air stream, which is equivalent to that the condensate flowing down from the first baffle 121a flows onto the second baffle 121b entirely, and likewise, the second baffle 121b and the third baffle 121c are disposed vertically adjacently, and the second baffle 121b is located upstream of the third baffle 121c in the direction of flow of the condensate, and the horizontal projection of the second baffle 121b is located in the horizontal projection area of the third baffle 121c, which is equivalent to that the condensate flowing down from the second baffle 121b also flows onto the third baffle 121c entirely. With continued reference to fig. 6 and 7, the third deflector 121c and the fourth deflector 121d are disposed vertically adjacent to each other, and the third deflector 121c is located upstream of the fourth deflector 121d in the condensate flow direction, and only one of the horizontal projections of the third deflector 121c is located in the horizontal projection area of the fourth deflector 121d, so that only a portion of the condensate flowing down from the third deflector 121c flows onto the fourth deflector 121d, and another portion flows directly to the drain port 11d without passing through the fourth deflector 121d, or only a portion of the condensate flowing down from the third deflector 121c flows onto the fourth deflector 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. 6 and 7, for example, in another embodiment, please refer to fig. 9, for convenience of description, two opposite sides of the baffle 121 along the airflow direction may be referred to as a first side and a second side, respectively, the first side in fig. 9 is located upstream of the second side along the airflow direction, and in some embodiments, the first side may also be located downstream of the second side along the airflow direction, which is equivalent to that the positions of the first side and the second side may be interchanged. The horizontal projection of the first side of the first baffle 121a and the horizontal projection of the second side of the second baffle 121b in fig. 9 are located in the horizontal projection area of the second baffle 121b, and 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 located in the horizontal projection area of the third baffle 121c, which corresponds to that the condensate flowing down from the first side of the first baffle 121a flows 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 flows onto the third baffle 121c, and the condensate flowing down from the first side of the second baffle 121b does not flow onto the third baffle 121c, that is, the baffle 121 located downstream in the condensate flow direction may receive a portion of the condensate flowing down from the adjacent and upstream baffle 121.

In the flow guide assembly 12 shown in fig. 6 and 9, the downstream flow guide plates 121 can each receive at least part of condensate flowing down on the adjacent and upstream flow guide plates 121, and in another embodiment, referring to fig. 10, the relative positions of the first flow guide plates 121a, the second flow guide plates 121b and the third flow guide plates 121c may also be: the horizontal projection of the first side of the first deflector 121a is located in the horizontal projection area of the second deflector 121b, the horizontal projection of the second side of the first deflector 121a is located in the horizontal projection area of the third deflector 121c, the horizontal projection of the second side of the second deflector 121b is offset from the horizontal projection of the first side of the third deflector 121c, that is to say, the condensate flowing down from the first side of the first deflector 121a flows onto the second deflector 121b, the condensate flowing down from the second side of the first deflector 121a flows onto the third deflector 121c, but the condensate flowing down from the second side of the second deflector 121b does not flow onto the third deflector 121c, but rather keeps away from the third deflector 121c, that is to say, the second deflector 121b can hold the portion of condensate flowing down on the adjacent and upstream first deflector 121a, but the third deflector 121c does not hold the portion of condensate flowing down on the upstream second deflector 121b, rather than the adjacent vertical deflector 121b, which is satisfied by the relative vertical position of the adjacent deflector 121: the downstream deflector 121 may receive at least part of the condensate flowing down from the upstream deflector 121 in the condensate flow direction.

The guide plates 121 positioned at the downstream of the condensate flow direction are used for accommodating at least part of condensate flowing down on the adjacent guide plates 121 positioned at the upstream, so that a water curtain can be formed between the two adjacent guide plates 121, the flow speed of the condensate can be slowed down, and the condensation and filtering and chip removing effects can be further improved. Particularly, when at least some of the plurality of baffles 121 can also guide condensate to flow to two opposite sides of the baffles 121 along the airflow direction, the condensation and filtering and chip removing effects of the condenser 10 can be greatly improved.

In addition, referring to fig. 10, although the third deflector 121c in fig. 10 does not receive condensate flowing down the adjacent and upstream second deflector 121b, condensate flowing down the second side of the second deflector 121b forms a single water curtain alone, that is, the deflector 12 shown in fig. 9 increases the number of water curtains on the lower side of the third deflector 121c compared to the deflector 12 shown in fig. 6, thereby enhancing the condensation and dust filtering effects of the condenser 10.

In another embodiment, referring to fig. 11, the flow guiding assembly 12 may also be a plurality of flow guiding plates 121, and part of the flow guiding plates 121 are vertically layered, and part of the flow guiding plates 121 are laterally spaced, that is, the flow guiding assembly 12 shown in fig. 11 is also a multi-layer structure, and at least one layer of the flow guiding assembly 12 shown in fig. 11 may be provided with at least two flow guiding plates 121, and at least two flow guiding plates 121 of the same layer are laterally spaced, compared with the flow guiding assembly 12 shown in fig. 5 to 10. It should be noted that the baffle 121 of any of the foregoing embodiments may be used in the baffle assembly 12 shown in fig. 11, and will not be described herein.

Wherein, the inner cylinder can be a non-porous inner cylinder or a porous inner cylinder. When the inner cylinder is a porous inner cylinder, the water is contained by the outer cylinder.
