[0038] As Figures 1 to 5 shown, the present embodiment provides a fresh air device 10, which includes a water storage base 100, a duct main body 200, and a water receiving assembly. The water storage base 100 has a water tank 110 therein for containing clean water. The duct main body 200 is disposed above the water storage base 100, and a first side of the duct main body 200 extends to an outer side of the water storage base 100, forming an extension 210 at the outer side of the water storage base 100. External fresh air enters the duct main body 200 along an extension direction through the extension 210. The water receiving assembly is formed at least at a bottom end of the extension 210, and the water receiving assembly extends into a top portion of the water tank 110. The water receiving assembly is used to receive condensed water on a side wall 230 of the extension and introduce the condensed water into the water tank 110.

[0039] The specific shape of the water storage base 100 and the water tank 110 can be selected as needed. As a specific embodiment, as shown in Figure 5 , the main body shape of the water storage base 100 and the water tank 110 is a cuboid. The water tank 110 is used to store clean water, and the water tank 110 is disposed in the water storage base 100. Here, the clean water refers to water used to dissolve pollutants such as dust, particulate matter, lint, and water-soluble harmful substances in the air, and water used to increase the humidity in the air.

[0040] The shape of the air duct body 200 is not limited, and the air duct body 200 can be used to form an air duct. For the convenience of description and understanding, the fresh air inlet side of the air duct body 200 is taken as the front side, that is, the first side of the air duct body 200 is taken as the front side (hereinafter, if not specifically stated, the direction is taken as the above direction). As shown in FIG. 1, Figure 4 The air duct body 200 mainly includes a side wall of the air duct, a front wall of the air duct, and a rear wall of the air duct. The side wall of the air duct, the front wall of the air duct, and the rear wall of the air duct enclose a space region with an upward and downward opening. The air duct is formed in the space region. It is obvious that the shape of the air duct body 200 is only exemplary and is not unique.

[0041] The specific way in which the air duct body 200 forms the air duct is not limited. For example, the air duct body 200 can independently form the air duct, or cooperate with other structures to form the air duct. In the embodiment, as shown in FIG. 1, Figure 6 The air duct body 200 is arranged above the water storage base 100, and a partition plate 700 is arranged in the air duct body 200. The partition plate 700 divides the space enclosed by the air duct body 200 into two air ducts. One air duct is a water washing air duct 240 located below, which is enclosed by the air duct body 200, the cleaning water in the water tank 110, and the partition plate 700. The other air duct is a fresh air air duct 220 located above the water washing air duct 240, which is enclosed by the air duct body 200, the upper shell 400, and the partition plate 700.

[0042] The type and number of air ducts formed by the air duct body 200 can be selected. In the embodiment, the air duct body 200 forms two air ducts. One type of air duct is the fresh air air duct 220, which is used to suck fresh air from the outdoor into the indoor to improve the freshness of the indoor air and increase the oxygen content of the indoor air. One type of air duct is the water washing air duct 240, which is used to clean dust, particulate matter, lint, or water-soluble harmful substances in the air, and increase the humidity of the air. That is, the fresh air device 10 provided in the embodiment has a water washing function, a fresh air function, or both a water washing function and a fresh air function.

[0043] The first side of the air duct body 200 extends to the outer side of the water storage base 100, that is, the fresh air intake side of the air duct body 200 extends to the outer side of the water storage base 100, or it can be understood as the front side of the air duct body 200 extending to the outer side of the water storage base 100. This forms an extension 210 located on the outer side of the water storage base 100, or it can be understood as the extension 210 being located on the front side of the water storage base 100, and external fresh air enters the air duct body 200 along the extension direction through the extension 210. In this embodiment, external fresh air enters the air duct body 200 through the front side of the air duct body 200 and passes through the air duct body 200 from front to back. The air duct body 200 forms an extension 210 facing the outer side of the water storage base 100, and air is intaked through the extension 210. This increases the contact time and contact area between the clean water in the water tank 110 and the fresh air, so as to fully purify and humidify the air, while making the entire air conditioner 1 more compact and saving space.

[0044] The specific type of water-collecting component can be selected according to needs. For example, the water-collecting component can be a water-collecting platform or a water-collecting trough 321. The water-collecting component can be used to collect condensate on the side wall 230 of the extension and introduce the condensate into the water tank 110. The fresh air inlet 411 is located on the extension 210. Due to the temperature difference between indoors and outdoors, condensate is most likely to form on the side wall 230 of the extension. Moreover, since the extension 210 is located outside the water storage base 100, the condensate on the side wall 230 of the extension is most likely to flow out of the fresh air device 10, causing inconvenience to people. The inventors cleverly guided the condensate on the side wall 230 of the extension into the water tank 110 through the water-collecting component, which not only prevented the condensate from flowing out of the fresh air device 10 and causing inconvenience to people, but also gave the condensate a new use, that is, to purify and humidify the air.

[0045] Therefore, since the first side of the air duct body 200 extends to the outside of the water storage base 100 to form an extension 210, which is used to introduce fresh air, this increases the contact time and contact area between the air and the clean water in the water tank 110, and also makes the overall structure of the fresh air device 10 more compact and saves space. The bottom end of the extension 210 forms a water receiving component, which prevents condensate generated on the side wall 230 of the extension located outside the water storage base 100 from flowing out of the fresh air device 10 and causing inconvenience.

[0046] In some other embodiments, the water receiving assembly includes a water receiving portion 310, which is formed by folding outward from the bottom end of the side wall 230 of the extension portion. The water receiving portion 310 is used to collect condensate on the side wall 230 of the extension portion. The specific shape of the water receiving portion 310 is not limited; for example, it can be a water receiving platform or a groove. The water receiving portion 310 is formed by folding outward from the bottom end of the side wall 230 of the extension portion, that is, the bottom end of the side wall 230 of the extension portion forms a flange facing outward from the air duct to collect condensate on the outer side of the side wall 230 of the extension portion. The water receiving portion 310 and the extension portion 210 are integrally formed, which can prevent water leakage. Obviously, this is only exemplary; for example, the water receiving portion 310 and the extension portion 210 may be two separate components.

[0047] In some other embodiments, the water receiving assembly further includes a receiving section 320, which extends downward from the water storage base 100 toward the extension 210. As can be seen from the above-described orientation, the receiving section 320 extends forward from the water storage base 100 and is located below the extension 210. The receiving section 320 has a water receiving groove 321 located directly below the water receiving portion 310, extending into the top of the water tank 110. The water receiving groove 321 is used to collect condensate dripping from the water receiving portion 310 and to guide the condensate into the water tank 110. The water receiving groove 321 further prevents condensate on the extension 210 from flowing out of the fresh air device 10.

[0048] In some other embodiments, the water receiving part 310 and the water receiving trough 321 gradually slope downwards toward the water tank 110 so that the condensate inside flows into the water tank 110 under the action of gravity. Since the condensate in the water receiving trough 321 and the water receiving part 310 eventually flows into the water tank 110, the closer the water receiving trough 321 and the water receiving part 310 are to the water tank 110, the more downwards they slope, so that the condensate can automatically flow into the water tank 110 under the action of gravity. A stop 311 extends upwards from the end of the water receiving part 310 near the water tank 110, that is, a stop 311 extends upwards from the lowest point of the water receiving part 310. The stop 311 is used to prevent the condensate from continuing to flow downwards and to guide the condensate into the water receiving trough 321.

[0049] In some other embodiments, the fresh air device 10 further includes an upper housing 400, which covers the air duct body 200 and has a fresh air inlet section 410 adapted to the extension 210. A fresh air inlet 411 is formed on the end face of the fresh air inlet section 410. As can be seen from the orientation defined above, the fresh air inlet 411 is formed on the front end face of the fresh air inlet section 410. External fresh air enters the air duct body 200 along the extension direction through the fresh air inlet 411, that is, external fresh air enters the air duct body 200 from the front and flows to the rear. The specific shape of the upper housing 400 is not limited, as long as the upper housing 400 can completely cover the air duct body 200. The upper housing 400 prevents condensate from being directly exposed to the outside of the fresh air device 10, and prevents condensate from splashing onto other parts and from flowing out. The formation of the fresh air inlet 411 on the end face of the fresh air inlet section 410 ensures that the flow direction of fresh air entering the fresh air inlet 411 is consistent with the flow direction within the air duct body 200.

[0050] In some other embodiments, the fresh air device 10 further includes a partition 700 disposed within the duct body 200. The partition 700 forms a lower, extending water-washing duct 240 between itself and the clean water in the water tank 110, and an upper, extending fresh air duct 220 between itself and the upper housing 400. The partition 700 divides the duct body 200 into two parallel fresh air ducts 220 and a water-washing duct 240. With respect to the aforementioned orientation, the extending directions of the fresh air duct 220 and the water-washing duct 240 are the same. This ensures that the gas flows in the same direction within the fresh air duct 220 and the water-washing duct 240, allowing gas to flow within either the fresh air duct 220 or the water-washing duct 240 using only one set of fan assembly 800.

[0051] In some other embodiments, the partition 700 includes a water washing inlet section 710 located within the extension 210, with a water washing inlet 711 formed on the water washing inlet section 710. The water washing inlet 711 is configured to be controlled to communicate with or be closed to the fresh air duct 220, allowing fresh air in the fresh air duct 220 to enter the water washing duct 240 through the water washing inlet 711. That is, when the water washing inlet 711 is open, it communicates with the fresh air duct 220, and fresh air flows out of the water washing duct 240. In this case, the air conditioner simultaneously has both fresh air and water washing functions. When the water washing inlet 711 is closed, it is closed to the fresh air duct 220, meaning that fresh air cannot flow into the water washing duct 240 through the water washing inlet 711, and fresh air flows out of the fresh air duct 220. In this case, the air conditioner also has a fresh air function. This makes the structure compact, the fresh air unit 10 versatile, and easy to switch between different functions.

[0052] In this embodiment, the fresh air device 10 further includes an inlet baffle 500, which is used to open or close the water washing inlet 711. The arrangement of the inlet baffle 500 at the water washing inlet 711 is not limited, as long as it can be used to open and close the water washing inlet 711. For example, the inlet baffle 500 can slide, flip, or rotate relative to the water washing inlet 711 to block or move away from the water washing inlet 711. When the inlet baffle 500 blocks the water washing inlet 711, the water washing inlet 711 is closed, and air flows into the room from the fresh air duct 220. At this time, the air conditioner performs the fresh air function. When the inlet baffle 500 moves away from the water washing inlet 711, the water washing inlet 711 is opened, and air flows into the room from the water washing duct 240. At this time, the air conditioner performs the water washing function.

[0053] In some other embodiments, the inlet baffle 500 is pivotally disposed at the water washing inlet 711. The inlet baffle 500 rotates toward the water washing duct 240 to open the water washing inlet 711, and rotates toward the water washing inlet 711 to close the water washing inlet 711. This prevents the inlet baffle 500 from obstructing the fresh air duct 220 and the fresh air inlet 411, thus affecting the air intake of the fresh air duct 220.

[0054] In some other embodiments, the inlet baffle 500 is used to seal the contact area with the water-washing inlet section 710 to ensure the airtightness of the fresh air duct 220. This is to prevent air leakage from the fresh air duct 220, thereby preventing the fresh air duct 220 from drawing in indoor air and improving the efficiency of the fresh air duct 220 in drawing in fresh outdoor air.

[0055] In other embodiments, the inlet baffle 500 contacts the protruding sealing teeth 510 at the water washing inlet section 710, and the water washing inlet section 710 has a sealing groove at its contact with the inlet baffle 500. When the inlet baffle 500 rotates to contact the water washing inlet section 710, the sealing teeth 510 on the inlet baffle 500 are accommodated in the sealing groove on the water washing inlet section 710 to ensure the airtightness of the fresh air duct 220. This achieves sealing by changing the airflow direction, or in other words, by increasing the airflow path. This sealing method is simple and ensures the sealing of the inlet baffle 500 even with frequent rotation. Furthermore, the protruding sealing teeth 510 on the inlet baffle 500 and the sealing groove formed by the water washing inlet section 710 prevent obstruction of the airflow within the water washing duct 240.

[0056] In some other embodiments, the water washing inlet section 710 gradually slopes downwards in the direction away from the water tank 110 to reduce the flow resistance of fresh air within the water washing duct 240. With the aforementioned orientation, the water washing inlet section 710 gradually slopes downwards in the forward direction, that is, the water washing inlet section 710 slopes towards the fresh air inlet 411. This makes the velocity of the fresh air entering the water washing duct 240 close to its flow velocity within the water washing duct 240, which can reduce the flow resistance of the fresh air within the water washing duct 240.

[0057] In some other embodiments, the upper housing 400 has a first fresh air outlet 420 and a second fresh air outlet 430 arranged side-by-side and located away from the extension 210. That is, the first fresh air outlet 420 and the second fresh air outlet 430 of the extension 210 are arranged side-by-side on the rear side of the upper housing 400. The fresh air duct 220 is connected to the first fresh air outlet 420, and the water washing duct 240 is connected to the second fresh air outlet 430. As can be seen from the above description, both the fresh air inlet 411 and the water washing inlet 711 are located on the front side. Therefore, fresh air flows from the front side of the water washing duct 240 and the fresh air duct 220 to the rear side.

[0058] The fresh air device 10 also includes an outlet baffle 600, which is pivotally located at the boundary between the first fresh air outlet 420 and the second fresh air outlet 430. The outlet baffle 600 rotates toward the first fresh air outlet 420 to open the second fresh air outlet 430 and close the first fresh air outlet 420; it also rotates toward the second fresh air outlet 430 to open the first fresh air outlet 420 and close the second fresh air outlet 430. The fresh air duct 220 and the water washing duct 240 are arranged parallel vertically. The first fresh air outlet 420 and the second fresh air outlet 430 are arranged side-by-side at the rear, while the fresh air inlet 411 and the water washing inlet 711 are arranged at the front. This makes the flow direction of fresh air in the fresh air duct 220 and the water washing duct 240 similar. Only one set of fan assembly 800 is needed to make the fresh air flow in the fresh air duct 220 or the water washing duct 240, resulting in a simple and compact structure.

[0059] This allows a single outlet baffle 600 to control the opening and closing of the first fresh air outlet 420 and the second fresh air outlet 430. For example... Figure 4As shown, when the outlet baffle 600 closes the first fresh air outlet 420 and simultaneously opens the second fresh air outlet 430, and the inlet baffle 500 opens the water washing inlet 711, air passes through the water washing duct 240, and the air conditioner simultaneously performs both fresh air and water washing functions. Conversely, when the outlet baffle 600 opens the first fresh air outlet 420 and simultaneously closes the second fresh air outlet 430, and the inlet baffle 500 closes the water washing inlet 711, air passes through the fresh air duct 220, and the air conditioner performs the fresh air function. This makes the structure of the fresh air device 10 simple and compact; switching between different functions of the air conditioner 1 can be achieved simply by controlling the rotation of the inlet baffle 500 and the outlet baffle 600, resulting in a simple control logic.

[0060] According to a second aspect of the present invention, the present invention also provides an air conditioner 1, which includes a fresh air device 10 as described above. Since the air conditioner 1 includes any of the fresh air devices 10 described above, the air conditioner 1 possesses the technical effects of any of the aforementioned fresh air devices 10, which will not be elaborated further here.
