Fresh air assembly and fresh air air conditioner

Abstract

The application provides a fresh air assembly and a fresh air conditioner. When the fresh air assembly is installed at the back of a ducted air conditioner, an installation opening is formed at the bottom of an air inlet box, so that a user can conveniently dismount and mount a filter module. When the filter module is installed in an air inlet cavity, a filtering part of the filter module covers an air inlet to filter air entering the filter module. Condensed water formed on the inner wall of the filtering part slides to the bottom of the filtering part under the action of gravity, and then flows into a condensation prevention part to be absorbed, so that the condensed water formed in the filter module does not flow out of the fresh air assembly and drip. In addition, the condensation prevention part prevents heat exchange between the bottom of the air inlet cavity and the external space, so that moisture in the external space does not condense when contacting the outer side wall of the bottom of the filter module, thereby effectively preventing the condensed water from condensing on the outer side wall of the bottom of the filter module and dripping, and improving the user experience.

Description

Technical Field

[0001] This application relates to the field of air conditioning equipment technology, and more particularly to a fresh air component and a fresh air air conditioner. Background Technology

[0002] Because the indoor units of residential central air conditioning are ceiling-mounted (also known as ducted units), they have the advantages of aesthetically pleasing installation and small footprint, and their market share is constantly increasing.

[0003] Currently, most household ducted air conditioners can only exchange heat and circulate indoor air. When users close doors and windows, the air quality will deteriorate over time, leading to a decline in user experience. By adding a fresh air component to the structure of the ducted air conditioner, fresh outdoor air can be introduced to achieve indoor and outdoor air circulation.

[0004] However, the large temperature difference between outdoor and indoor air causes condensation to form inside and outside the fresh air system, which then drips onto the ground, resulting in a poor user experience. Summary of the Invention

[0005] This application provides a fresh air component and a fresh air air conditioner to solve the technical problem that existing fresh air components are prone to dripping condensate.

[0006] On the one hand, this application provides a fresh air component, including:

[0007] Fan module;

[0008] An air inlet box has an air inlet, an air outlet, and a mounting port. The air inlet is connected to the air outlet and forms an air inlet cavity. The mounting port is located at the bottom of the air inlet box and is connected to the air inlet cavity. The air outlet is connected to the air inlet of the fan module.

[0009] A filter module is detachably installed in the air inlet cavity through the mounting port. The filter module includes a filter section and an anti-condensation section. The anti-condensation section is located at the bottom of the filter section and is used to absorb condensation generated by the filter section and to isolate the bottom of the air inlet cavity from the external space.

[0010] In one possible implementation of this application, the filter section includes a filter bracket and a filter screen, the filter screen is installed in the filter bracket, and the plane of the filter screen is parallel to the plane of the air inlet;

[0011] The anti-condensation section includes an anti-condensation bracket and a water-absorbing and heat-insulating component. The anti-condensation bracket is connected to the bottom of the filter bracket, and the water-absorbing and heat-insulating component is installed inside the anti-condensation bracket.

[0012] In one possible implementation of this application, the filter bracket and the anti-condensation bracket are integrated, and a V-shaped water collection plate is formed at the connection between the filter bracket and the anti-condensation bracket. The V-shaped water collection plate protrudes in a direction away from the air inlet and is perpendicular to the plane where the air inlet is located.

[0013] In one possible implementation of this application, the filter section further includes a limiting plate, which is installed on the side of the V-shaped water collection plate near the air inlet, and the plane of the limiting plate is perpendicular to the plane of the air inlet.

[0014] When the filter screen is installed in the filter bracket, the limiting plate is used to restrict the movement of the filter screen toward the air inlet.

[0015] In one possible implementation of this application, a plurality of spaced-apart guide ribs are formed on the V-shaped water collection plate, and the extending direction of the guide ribs is parallel to the plane where the air inlet is located.

[0016] In one possible implementation of this application, the V-shaped water collection plate includes a first plate and a second plate connected to each other, and a water passage hole is formed at the connection between the first plate and the second plate. The water passage hole is used to guide the condensate on the side of the V-shaped water collection plate away from the water-absorbing and heat-insulating component to the water-absorbing and heat-insulating component.

[0017] The V-shaped water collection plate also includes an overflow pipe, one end of which is connected to the water passage hole, and the other end extends vertically upward.

[0018] In one possible implementation of this application, the anti-condensation bracket has a first mounting cavity and a second mounting cavity that are isolated from each other. The second mounting cavity is located at the bottom of the first mounting cavity on the side away from the filter section, and the opening of the first mounting cavity is disposed away from the air inlet.

[0019] The water-absorbing and heat-insulating component includes a water-absorbing component and a heat-insulating component. The water-absorbing component is installed in the first mounting cavity, and the heat-insulating component is installed in the second mounting cavity.

[0020] In one possible implementation of this application, the air inlet box includes a front air box and a rear air box that are interconnected, the air inlet is opened on the front air box, the air outlet and the mounting port are opened on the rear air box, and the filter module is detachably installed in the rear air box;

[0021] The inner wall of the front air box is provided with multiple water-blocking ribs at intervals, and the extension direction of the water-blocking ribs is perpendicular to the plane where the air inlet is located.

[0022] In one possible implementation of this application, the front air box includes a diffuser section and an air supply section that are interconnected, the air inlet is opened on the diffuser section, and the air supply section is connected to the rear air box;

[0023] A water collection trough is formed at the connection between the air supply section and the diffuser section, and the water collection trough is located on the lower side of the diffuser section in the vertical direction.

[0024] On the other hand, this application also provides a fresh air conditioner, which includes an indoor unit and an outdoor unit that are interconnected, as well as the fresh air component described above. The indoor unit has an air inlet, the fresh air component is installed on the indoor unit, and the air outlet of the fresh air component is arranged facing the air inlet of the indoor unit.

[0025] This application provides a fresh air assembly and a fresh air air conditioner. When the fresh air assembly is installed on the back of a ducted air conditioner, an installation port is provided at the bottom of the air inlet box, allowing users to easily install and remove the filter module. When the filter module is installed in the air inlet cavity, the filter section of the filter module covers the air inlet to filter the air entering the fan module. Condensation formed on the inner wall of the filter section slides down to the bottom of the filter section under its own gravity and then flows into the anti-condensation section for absorption, thus preventing condensation formed inside the filter module from flowing out of the fresh air assembly and dripping. Furthermore, because the anti-condensation section isolates the bottom of the air inlet cavity from heat exchange with the external space, moisture in the external space will not condense upon contact with the outer wall of the bottom of the filter module, effectively preventing condensation and dripping, thus improving the user experience.

[0043] Please refer to Figures 1 to 5 This application provides a fresh air component 300, comprising:

[0044] Fan module 400;

[0045] The air inlet box 500 has an air inlet 512, an air outlet 521 and a mounting port 522. The air inlet 512 is connected to the air outlet 521 and forms an air inlet cavity 530. The mounting port 522 is located at the bottom of the air inlet box 500 and is connected to the air inlet cavity 532. The air outlet 521 is connected to the air inlet 420 of the ventilation module 400.

[0046] The filter module 600 is detachably installed in the air inlet cavity 530 through the mounting port 522. The filter module 600 includes a filter section 610 and an anti-condensation section 620. The anti-condensation section 620 is located at the bottom of the filter section 610 and is used to absorb the condensation generated by the filter section 610 and to isolate the bottom of the air inlet cavity 530 from the external space.

[0047] It should be noted that the fresh air assembly 300 provided in this application embodiment is applicable to a fresh air unit (not shown in the figure) or a fresh air air conditioner 100. The fan module 400 includes a fan impeller (not shown in the figure), a rotating motor (not shown in the figure), and a volute 410, with the duct housing and the volute 410 connected in sequence. The volute 410 may be composed of two volute housings (not shown in the figure), with the fan impeller and rotating motor installed inside the volute 410. The volute 410 is provided with an air inlet 420 and an air outlet 430. The air inlet 420 connects to the air outlet 430 and forms a fan cavity 440 inside the volute 410. The fan impeller and rotating motor are installed inside the fan cavity 440, and the air inlet cavity 530 is connected to the fan cavity 440 through the air inlet 420.

[0048] It should also be noted that the fresh air assembly 300 of this application is particularly suitable for ducted air conditioners. The ducted air conditioner is ceiling-mounted, while the fresh air assembly 300 is installed on the back of the ducted air conditioner, i.e., in the gap between the wall and the ducted air conditioner. After startup, the fresh air assembly 300 draws outdoor fresh air into the air intake box 500 through the air inlet 512. Due to the significant temperature difference between the outdoor and indoor environments and the air intake box 500, especially in summer when the external temperature is high, the moisture in the warmer fresh air drawn into the air intake cavity 530 easily condenses on the inner wall of the air intake box 500 upon cooling. For example… Figure 3 The first water accumulation point P1 and the second water accumulation point P2 in the system collect and form condensate, which then drips down. Furthermore, because the bottom of the fresh air assembly 300, mounted on the back of the duct unit, is exposed indoors, the indoor air passing through the bottom of the filter module 600 exchanges heat with the air at the bottom of the air inlet cavity 530. This also makes it easy for condensate to form on the outer wall of the bottom of the filter module 600 and drip down. For example... Figure 3 The third water accumulation point is P3. The condensate that forms on the inner wall of the air inlet box 500 and the outer wall of the bottom of the filter module 600 will drip onto the indoor floor, resulting in a poor user experience. Furthermore, this condensate may overflow into other electrical components, causing short circuits and damage, and affecting the normal operation of the fresh air assembly 300.

[0049] When the fresh air assembly 300 is installed on the back of the ducted air conditioner, the filter module 600 can be easily installed and removed by the user through the installation port 522 at the bottom of the air inlet box 500. When the filter module 600 is installed in the air inlet cavity 530, the filter section 610 of the filter module 600 covers the air inlet 420 to filter the air entering the fan module 400. Condensation formed on the inner wall of the filter section 610 will slide to the bottom of the filter section 610 under its own gravity, and then flow into the anti-condensation section 620 for absorption. This prevents condensation formed inside the filter module 600 from flowing out of the fresh air assembly 300 and dripping. Furthermore, because the anti-condensation section 620 isolates the bottom of the air inlet cavity 530 from heat exchange with the external space, moisture in the external space will not condense upon contact with the outer wall of the bottom of the filter module 600, effectively preventing condensation from forming on the outer wall of the bottom of the filter module 600 and dripping, thus improving the user experience.

[0050] Optionally, the air inlet 512 can be extended to the outdoor side; or a fresh air duct (not shown in the figure) can be installed on the air inlet 512, with the end of the fresh air duct away from the air inlet 512 located on the outdoor side.

[0051] Specifically, the filter module 600 is generally flat and rectangular, with a rectangular mounting port 522. This improves the utilization of the internal space of the air inlet box 500 and makes the structure of the fresh air assembly 300 more compact.

[0052] Specifically, the filter module 600 is snap-fitted to the air inlet box 500. This makes it easy for users to install and remove the filter module 600.

[0053] In some embodiments, the filter unit 610 includes a filter bracket 611 and a filter screen (not shown in the figure), the filter screen is installed in the filter bracket 611, and the plane where the filter screen is located is parallel to the plane where the air inlet 420 is located.

[0054] The anti-condensation unit 620 includes an anti-condensation bracket 621 and a water-absorbing and heat-insulating component 630. The anti-condensation bracket 621 is connected to the bottom of the filter bracket 611, and the water-absorbing and heat-insulating component 630 is installed inside the anti-condensation bracket 621.

[0055] By setting the filter screen perpendicular to the plane of the air inlet 420, it can provide the efficiency for fresh air to enter the fan module 400 through the filter screen.

[0056] Specifically, the filter covers the air inlet 420 of the entire fan module 400.

[0057] Furthermore, by connecting the anti-condensation bracket 621 to the bottom of the filter bracket 611 to install the absorbent insulation component 632, the installation stability of the absorbent insulation component 630 can be improved.

[0058] Preferably, the material of the water-absorbing and heat-insulating component 630 can be sponge.

[0059] Furthermore, in other embodiments, the material of the water-absorbing and heat-insulating component 630 may also be composite silicate or polyurethane, etc., without further limitation.

[0060] Specifically, both the filter support 611 and the anti-condensation support 621 are rectangular frames.

[0061] In particular, after the filter module 600 has been used for a period of time, the consumable material of the filter section 610, namely the filter screen, needs to be replaced to ensure the filtration effect of the filter module 600 on fresh air. The time interval is usually 1 to 3 months. At this time, the user can also remove the water-absorbing and heat-insulating component 630 in the anti-condensation section 620 for cleaning and dehydration or replace it.

[0062] In some embodiments, the filter bracket 611 and the anti-condensation bracket 621 are integrated, and a V-shaped water collection plate 640 is formed at the connection between the filter bracket 611 and the anti-condensation bracket 621. The V-shaped water collection plate 640 protrudes in a direction away from the air inlet 420 and is perpendicular to the plane where the air inlet 512 is located.

[0063] By integrating the filter bracket 611 and the anti-condensation bracket 621, both the filter bracket 611 and the anti-condensation bracket 621 use the V-shaped water collection plate 640 at the connection point as the support frame, which simplifies the structure of the filter bracket 611 and the anti-condensation bracket 621.

[0064] It is also understandable that in coastal areas or during the rainy season, the humidity in the air is high, resulting in a large amount of condensation on the inner wall of the filter bracket 611. Since the water absorption capacity of the water-absorbing insulation component 630 of the anti-condensation bracket 621 is limited, the water-absorbing insulation component 630 may lose its water absorption capacity in a short period of time. At this time, the excess condensation that the water-absorbing insulation component 630 cannot absorb may overflow from the fresh air assembly 300.

[0065] By protruding the V-shaped water collection plate 640 away from the air inlet 420, the condensate dripping from the inner wall of the filter bracket 611 can be guided to collect in the central recess of the V-shaped water collection plate 640. This allows the condensate dripping onto the V-shaped water collection plate 640 to be temporarily stored on it, and then flow downwards into the water-absorbing and heat-insulating component 630 under its own gravity to be absorbed. This increases the amount of condensate absorbed and stored by the filter module 600, thereby extending the service life of the filter module 600.

[0066] Specifically, the V-shaped water collection plate 640 includes a first plate 641 and a second plate 642 that are connected to each other, and the first plate 641 and the second plate 642 are set at an obtuse angle.

[0067] Furthermore, in other embodiments, the V-shaped water collection plate 640 may also be in other shapes, such as W-shaped, U-shaped, or wavy, to increase the volume of condensate stored, without being overly limited here.

[0068] In some embodiments, the filter section 610 further includes a limiting plate 612, which is installed on the side of the V-shaped water collection plate 640 near the air inlet 420. The plane of the limiting plate 612 is perpendicular to the plane of the air inlet 420. When the filter screen is installed in the filter bracket 611, the limiting plate 612 is used to restrict the filter screen from moving toward the air inlet 420.

[0069] By setting a limiting plate 612, and the limiting plate 612 is located on the side of the V-shaped water collection plate 640 near the air inlet 420, the limiting plate 612 and the V-shaped water collection plate 640 form an angled area on the side away from the air inlet 420; and the plane where the limiting plate 612 is located is perpendicular to the plane where the air inlet 420 is located, that is, the angled area is a 90° folded edge away from the air inlet 420.

[0070] On the one hand, the limiting plate 612 can effectively restrict the movement of the filter screen towards the air inlet 512; on the other hand, the angled area can significantly increase the volume of condensate water storage compared to the planar V-shaped water collection plate 640, further increasing the amount of condensate water absorbed and stored by the filter screen module 600, thereby further extending the service life of the filter screen module 600.

[0071] Furthermore, in some other embodiments, the included angle between the limiting plate 612 and the V-shaped water collection plate 640 can be 85° or 75°, etc., to improve the storage stability of condensate; the included angle between the limiting plate 612 and the V-shaped water collection plate 640 can also be 95° or 100°, etc., to improve the smoothness of condensate flowing from the V-shaped water collection plate 640 into the bottom anti-condensation bracket 621.

[0072] Please refer to Figure 3 , Figures 6 to 9 In some embodiments, a plurality of spaced-apart guide ribs 643 are formed on the V-shaped water collection plate 640, and the extending direction of the guide ribs 643 is parallel to the plane where the air inlet 420 is located.

[0073] By setting the drainage ribs 643, the condensate on the V-shaped water collection plate 640 can be diverted to the gap between the adjacent drainage ribs 643, thereby preventing the condensate on the V-shaped water collection plate 640 from being shaken out when the fresh air assembly 300 moves and vibrates, and improving the storage capacity and stability of the stored water in the V-shaped water collection plate 640.

[0074] Specifically, both the first plate 641 and the second plate 642 are provided with drainage ribs 643, and the drainage ribs 643 on the first plate 641 and the drainage ribs 643 on the second plate 642 are spaced apart, which allows the condensate flowing out of the gaps of the adjacent drainage ribs 643 to flow smoothly into the lower water-absorbing insulation component 630.

[0075] Furthermore, multiple water-blocking strips (not shown in the figure) are provided at intervals between any adjacent drainage ribs 643. The extension direction of the water-blocking strips is perpendicular to the extension direction of the drainage ribs 643, which can further improve the storage capacity of condensate and the stability of the stored water.

[0076] In some embodiments, the V-shaped water collection plate 640 includes a first plate 641 and a second plate 642 connected to each other. A water passage hole 644 is formed at the connection between the first plate 641 and the second plate 642. The water passage hole 644 is used to guide the condensate on the side of the V-shaped water collection plate 640 away from the water-absorbing and heat-insulating member 630 to the water-absorbing and heat-insulating member 630.

[0077] It is understandable that when the fan module 400 starts, the air inlet 420 is under negative pressure, and the surface of the V-shaped water collection plate 640 located near the air inlet 420 is also under negative pressure. Therefore, the condensate stored on the surface of the V-shaped water collection plate 640 may be sucked away by the fan module 400, which may cause damage to the fan module 400.

[0078] A V-shaped water collection plate 640 is formed by setting the first plate 641 and the second plate 642 at an obtuse angle, with the connection point of the first plate 641 and the second plate 642 being the protruding tip of the V-shaped water collection plate 640, which is also the lowest point in the vertical direction. This guides the condensate that slides onto the first plate 641 and the second plate 642 towards the connection point. Correspondingly, a water passage hole 644 is opened at the connection point of the first plate 641 and the second plate 642, which can smoothly drain all the condensate on the filter bracket 611 into the anti-condensation bracket 621 for absorption by the water-absorbing insulation component 630. This effectively prevents the fan module 400 from drawing in condensate.

[0079] In some embodiments, the V-shaped water collection plate 640 further includes an overflow pipe 645, one end of which is connected to a water passage hole 644, and the other end extends vertically upward.

[0080] By setting an overflow pipe 645, the condensate is stored in the V-shaped water collection plate 640 until it reaches the top of the overflow pipe 645 before flowing into the overflow pipe 645 and then into the anti-condensation bracket 621 where it is absorbed by the water-absorbing and heat-insulating component 630. This increases the amount of condensate absorbed and stored by the filter module 600, thereby extending the service life of the filter module 600.

[0081] Furthermore, the V-shaped water collection plate 640 also includes a baffle plate, which is disposed opposite to the limiting plate 612 on the other side of the first plate 641 and the second plate 642. The baffle plate, the limiting plate 612, the first plate 641 and the second plate 642 together form a groove structure, which can stably store condensate in the groove structure, thereby improving the stability of condensate storage in the filter module 600.

[0082] Correspondingly, in the vertical direction, the height of the overflow pipe 645 is not higher than the height of the limiting plate 612 or the baffle plate, so as to avoid the overflow of condensate in the groove structure.

[0083] In some embodiments, the anti-condensation bracket 621 has a first mounting cavity 622 and a second mounting cavity 623 that are isolated from each other. The second mounting cavity 623 is located at the bottom of the first mounting cavity 622 on the side away from the filter section 610, and the opening of the first mounting cavity 622 is disposed away from the air inlet 420.

[0084] The water-absorbing and heat-insulating component 630 includes a water-absorbing component 631 and a heat-insulating component 632. The water-absorbing component 631 is installed in the first mounting cavity 622, and the heat-insulating component 632 is installed in the second mounting cavity 623.

[0085] In the vertical direction, the water-absorbing component 631 and the heat-insulating component 632 are arranged sequentially away from the filter section 610. Since the first mounting cavity 622 and the second mounting cavity 623 are isolated from each other, condensate condensing inside the filter support 611 will only flow into the first mounting cavity 622 under its own gravity to be absorbed by the water-absorbing component 631, and will not flow into the second mounting cavity 623. This effectively avoids the heat-insulating component 630 absorbing too much condensate, which would severely affect its heat-insulating performance. This results in a more balanced condensate absorption and heat-insulating capacity of the anti-condensation section 620, thereby reducing the amount of condensate generated.

[0086] Specifically, both the water-absorbing component 631 and the heat-insulating component 632 are made of sponge, but the water-absorbing component 631 is made of a sponge type and / or structure with water-absorbing properties, while the heat-insulating component 632 is made of a sponge type and / or structure with heat-insulating properties.

[0087] In some embodiments, the air inlet box 500 includes a front air box 510 and a rear air box 520 that are connected to each other. An air inlet 512 is opened on the front air box 510, an air outlet 521 and a mounting port 522 are opened on the rear air box 520, and the filter module 600 is detachably installed in the rear air box 520.

[0088] Multiple water-blocking ribs 515 are spaced apart on the inner side wall of the front air box 510, and the extension direction of the water-blocking ribs 515 is perpendicular to the plane where the air inlet 420 is located.

[0089] It should be noted that fresh air enters from the air inlet 512, passes through the front air box 510 and the rear air box 520 in sequence, and then enters the fan module 400.

[0090] It should also be noted that the water vapor in the outdoor fresh air consists of water mist particles with a diameter of 0.01 to 0.15 mm. When the outdoor fresh air is drawn into the front air box 510 through the air inlet 512, the water mist particles located in the boundary layer of the fresh air flow may remain on the inner wall surface of the front air box 510. After a long period of operation, larger water droplets accumulate, and these water droplets are easy to flow out of the air inlet 500.

[0091] By providing multiple water-blocking ribs 515 at intervals on the inner sidewall, the water-blocking ribs 515 can block and disturb the boundary layer airflow of fresh air in the front air box 510, thereby increasing the pressure pulsation on the inner wall surface of the front air box 510, causing the boundary layer airflow of fresh air to form turbulence, thus effectively preventing small water mist particles in the boundary layer airflow of fresh air from remaining on the inner wall surface of the front air box 510, thereby reducing the formation of water droplets in the front air box 510.

[0092] Preferably, the cross-sectional shape of the water-retaining rib 515 is semi-circular, and the water-retaining rib 515 is a straight column. This makes the surface of the water-retaining rib 515 smooth, which can reduce the impact on the fresh air volume and effectively weaken the airflow impact, thereby reducing the air-induced noise in the front air box 510.

[0093] Specifically, the height of the water-blocking rib 515 is no more than 3mm, preferably 1mm. This ensures that the water-blocking rib 515 only acts on the boundary layer of the fresh airflow and does not affect the central airflow of the fresh airflow, thereby reducing the impact of the water-blocking rib 515 on the fresh air volume.

[0094] Furthermore, in some other embodiments, the cross-sectional shape of the water-blocking rib 515 can also be rectangular, and the water-blocking rib 515 as a whole can also be an S-shaped column or a C-shaped column, etc., to increase the water storage capacity of the water-blocking rib 515. No further limitations are made here.

[0095] In some embodiments, the front air box 510 includes a diffuser section 511 and an air supply section 514 that are interconnected, an air inlet 512 is opened on the diffuser section 511, and the air supply section 514 is connected to the rear air box 520.

[0096] A water collection trough 513 is formed at the connection between the air supply section 514 and the diffuser section 511. In the vertical direction, the water collection trough 513 is located on the lower side of the diffuser section 511.

[0097] It should be noted that the diffuser section 511 is funnel-shaped, meaning that the space gradually expands after the fresh air enters the air inlet 512. This can slow down the speed of the fresh air flow and increase the fresh air intake volume, but it is also easy for condensation to form on the inner wall surface of the diffuser section 511.

[0098] By setting a water collection tank 513 at the bottom of the diffuser section 511 away from the air inlet 512, the condensate formed on the inner wall of the diffuser section 511 and sliding down the surface of the diffuser section 511 can be contained, thereby effectively preventing the condensate of the diffuser section 511 from overflowing and dripping or flowing to other electrical components, thus improving the operational reliability of the fresh air assembly 300.

[0099] Specifically, the air supply section 514 and the rear air box 520 have roughly the same shape, both being cylindrical, and multiple water-blocking ribs 515 are arranged at intervals on the inner wall surface of the air supply section 514.

[0100] In particular, since the air supply section 514 is connected to the rear air box 520 and the opening of the anti-condensation bracket 621 is set to face the front air box 510, the water stored in the water baffle 515 on the inner wall of the air supply section 514 can also flow into the water-absorbing insulation component 630 in the anti-condensation bracket 621, thereby effectively preventing water overflow caused by excessive water storage in the air supply section 514.

[0101] Specifically, only the lower half of the inner wall of the air supply section 514 is equipped with water-blocking ribs 515.

[0102] This application also provides a fresh air conditioner 100, which includes an indoor unit 200 and an outdoor unit connected to each other, and a fresh air assembly 300 as described above. The indoor unit 200 has an air inlet, and the fresh air assembly 300 is mounted on the indoor unit 200, with the air outlet 521 of the fresh air assembly 300 facing the air inlet of the indoor unit 200. Since this fresh air conditioner 100 has the aforementioned fresh air assembly 300, it has all the same beneficial effects, which will not be described in detail here.
