[0045] like Figures 1 to 12As shown, this embodiment provides a fresh air device 10, which includes a filter assembly 200, which includes a filter housing 210, a filter element 220, and a damper assembly. The damper assembly includes a damper 231. The first sidewall 216 of the filter housing has a first filtered air inlet 211 and a second filtered air inlet 212. The filter element 220 is configured to filter air flowing into the filter housing 210 from the first filtered air inlet 211 and / or the second filtered air inlet 212. The damper 231 is configured to translate along a first direction on the first sidewall 216 of the filter housing to open the first filtered air inlet 211 or the second filtered air inlet 212; to translate along a second direction when translated along the first direction to a first position to switch between the first position and the second position; and to rotate relative to the first sidewall 216 of the filter housing in the second position to simultaneously open the first filtered air inlet 211 and the second filtered air inlet 212.

[0046] In this embodiment, the shape of the filter housing 210 is not limited and can be selected according to needs. For example, the shape of the filter housing 210 can be a rectangular parallelepiped or other irregular shapes. In this embodiment, the first side wall 216 of the filter housing can be the front side wall, rear side wall, right side wall, left side wall, upper side wall or lower side wall of the filter housing 210. As a specific embodiment, Figure 1 As shown, the first side wall 216 of the filter housing is one of the front side wall, the rear side wall, the right side wall, and the left side wall of the filter housing 210 .

[0047] In this embodiment, the specific uses of the first filtered air inlet 211 and the second filtered air inlet 212 are not limited and can be selected as needed. As a specific embodiment, the first filtered air inlet 211 is used to communicate with the indoor environment, and the second filtered air inlet 212 is used to communicate with the outdoor environment. This allows the fresh air device 10 to simultaneously introduce indoor air when introducing outdoor air to mix with the outdoor air in advance, thereby avoiding the introduced outdoor air from being too cold or too hot. In this embodiment, the shapes of the first filtered air inlet 211 and the second filtered air inlet 212 are not limited and can be selected as needed.

[0048] In this embodiment, the relative positions of the first filtered air inlet 211 and the second filtered air inlet 212 are not limited and can be selected according to needs. Figure 1 As shown, the center of the first filtered air inlet 211 and the center of the second filtered air inlet 212 are on the same horizontal plane. Obviously, this is merely an example and is not exclusive. For example, the center of the first filtered air inlet 211 may be lower than the center of the second filtered air inlet 212, that is, the second filtered air inlet 212 is located diagonally above the first filtered air inlet 211.

[0049] In this embodiment, the location of the filter element 220 is not specifically limited and can be selected according to needs. Figure 1 and Figure 2 As shown, the filter element 220 is disposed in the filter housing 210. Obviously, this is only exemplary and not exclusive. For example, the filter element 220 is disposed in the first filter air inlet 211 and / or the second filter air inlet 212.

[0050] In this embodiment, the damper 231 is configured to translate along the first side wall 216 of the filter housing to open the first filter air inlet 211 or the second filter air inlet 212. The first translation direction of the damper 231 is not specifically limited and can be selected as needed. As a specific embodiment, Figure 1 As shown, the centers of the first filtered air inlet 211 and the second filtered air inlet 212 are on the same horizontal plane. The damper 231 first moves horizontally to open the first filtered air inlet 211 or the second filtered air inlet 212. This makes the structure of the fresh air device 10 relatively compact. Obviously, this is merely an example and not the only one. For example, the damper 231 can also move diagonally upward or diagonally upward to open the first filtered air inlet 211 or the second filtered air inlet 212.

[0051] In this embodiment, the specific position of the first position is not limited and can be selected as needed. As a specific embodiment, Figure 1 As shown, when the damper 231 is in the first position, its pivot shaft 233 is located between the first filtered air inlet 211 and the second filtered air inlet 212. Obviously, this is only exemplary and not exclusive.

[0052] In this embodiment, the second translation direction is not in the same direction as the first translation direction, that is, the first translation direction and the second translation direction intersect. As a specific embodiment, Figures 1 to 5 As shown, the first translation direction is perpendicular to the second translation direction. Obviously, this is only exemplary and not exclusive.

[0053] In some cases, a heating element is provided at the second filtered air inlet 212 to preheat the fresh air. If the damper 231 rotates directly, structural interference will occur between the damper 231 and the heating element, hindering the rotation of the damper 231. This arrangement of the damper 231 can avoid structural interference between the damper 231 and other structural components. At the same time, one damper 231 can enable the first filtered air inlet 211 and the second filtered air inlet 212 to be opened separately or simultaneously, so as to meet the needs of the fresh air device 10 for independently taking in indoor air, independently taking in outdoor air, and simultaneously taking in indoor and outdoor air, thereby diversifying the functions of the fresh air device 10.

[0054] In some other embodiments, the damper assembly includes a pivot shaft 233, an output shaft 235, and a first drive mechanism 236. The pivot shaft 233 is disposed on the damper 231. The output shaft 235 is configured to be disconnected from the pivot shaft 233 when the damper 231 is in the first position, and to be coaxially connected to the pivot shaft 233 when the damper 231 is in the second position to drive the pivot shaft 233 to rotate. The first drive mechanism 236 is used to drive the output shaft 235 to rotate.

[0055] In this embodiment, the extending direction of the pivot shaft 233 is not specifically limited and can be selected according to needs. Figures 1 to 5 As shown, the extension direction of the pivot axis 233 is consistent with the second direction, that is, the pivot axis 233 is arranged in the vertical direction. Obviously, this is only exemplary and not exclusive. For example, the pivot axis 233 can be arranged tilted upward.

[0056] In this embodiment, the direction of the output shaft 235 is related to the direction of the pivot shaft 233, that is, when the damper 231 is in the second position, the direction of the output shaft 235 is consistent with the direction of the pivot shaft 233, that is, the output shaft 235 is coaxial with the pivot shaft 233. In other words, when the damper 231 is in the second position, the pivot shaft 233 and the output shaft 235 are both in a vertical direction. The pivot shaft 233 is in an upward direction, and the output shaft 235 is also in an upward direction. This allows the output shaft 235 to be coaxially connected to the pivot shaft 233 when the damper 231 is in the second position. Figures 1 to 5 As shown, the pivot shaft 233 is arranged in the vertical direction, and the output shaft 235 is also arranged in the vertical direction. Obviously, this is only exemplary and not exclusive.

[0057] In this embodiment, the specific method of coaxially connecting the output shaft 235 and the pivot shaft 233 is not limited and can be selected according to needs. For example, the output shaft 235 and the pivot shaft 233 are connected by electromagnetic adsorption, adhesive connection, or vacuum adsorption.

[0058] In this embodiment, when the damper 231 is in the first position, the output shaft 235 is disconnected from the pivot shaft 233, thereby preventing the output shaft 235 from affecting the translation of the damper 231 along the first direction. When the damper 231 is in the second position, the output shaft 235 is connected to the pivot shaft 233 to drive the pivot shaft 233 to rotate.

[0059] In some other embodiments, a magnetic attraction member 234 is provided at the first end of the pivot shaft 233. The output shaft 235 is arranged along the second direction and has an electromagnetic attraction member 237 disposed thereon, configured to attract the pivot shaft 233 thereto along the second direction when the damper 231 translates to the first position.

[0060] In this embodiment, the output shaft 235 is arranged along the second direction. The magnetic attraction between the output shaft 235 and the pivot shaft 233 is used to connect the output shaft 235 and the pivot shaft 233, and also to move the pivot shaft 233 and the damper 231 along the second direction. This simple structure makes the fresh air device 10 compact.

[0061] In other embodiments, the first direction is horizontal and the second direction is vertical. The output shaft 235 is disposed above the pivot shaft 233. The pivot shaft 233 switches between the first position and the second position under the force of gravity and the drive of the magnetic attraction member 234 and the electromagnetic attraction member 237. This structure of the fresh air device 10 is simple, energy-efficient, and compact. Obviously, this is not the only embodiment. For example, two electromagnetic attraction members 237 may be disposed on either side of the pivot shaft 233 to control the switching of the damper 231 between the first position and the second position.

[0062] In some other embodiments, the filter housing 210 further includes a first groove 214 and a second groove 215. The first groove 214 is provided along a first direction on the first side wall 216 of the filter housing and is located above the pivot shaft 233, for allowing the first end of the pivot shaft 233 to translate and rotate along the first groove and switch between the first position and the second position.

[0063] The length direction of the second groove 215 is set along the first direction on the first side wall 216 of the filter housing, located on the lower side of the pivot shaft 233, and is used for the second end of the pivot shaft 233 to translate, rotate, and switch between the first position and the second position. This fresh air device 10 has a simple and compact structure. Obviously, the way in which the damper 231 is set in the first groove 214 and the second groove 215 through the pivot shaft 233 to achieve its translation and rotation is only exemplary and not the only one. For example, the first groove 214 and the second groove 215 are located between the upper side and the lower side of the damper 231, and the corresponding positions of the damper 231 cooperate with the first groove 214 and the second groove 215 to achieve the translation and rotation of the damper 231 on the first side wall 216 of the filter housing.

[0064] In some other embodiments, the fresh air device 10 further includes a sensor assembly 240. The sensor assembly 240 is disposed in the second groove 215 and is configured to be pressed by the second end of the pivot shaft 233 when the pivot shaft 233 translates to the first position along the first direction to detect that the pivot shaft 233 translates to the first position.

[0065] In this embodiment, the sensor assembly 240 may include a pressure sensor or a capacitive sensor. When the damper 231 moves to the first position, the second end of the pivot shaft 233, i.e., the bottom end of the pivot shaft 233, applies pressure to the sensor assembly 240, thereby determining that the damper 231 is in the first position. When the damper 231 moves out of the first position, the bottom end of the pivot shaft 233 no longer applies pressure to the sensor assembly 240, thereby determining that the damper 231 has left the first position. This makes the structure of the fresh air device 10 simple and compact.

[0066] In some other embodiments, the damper assembly further includes a second drive mechanism configured to cooperate with the damper 231 to drive the damper 231 to translate in the first direction when the damper 231 is in the first position, and to disengage from the damper 231 when the damper 231 is in the second position.

[0067] In this embodiment, the type of the second drive mechanism is not limited and can be selected as needed. The second drive mechanism can be used to drive the damper 231 to translate along the first direction. When the damper 231 is in the second position, the second drive mechanism disengages from the damper 231, thereby preventing the second drive mechanism from affecting the rotation of the damper 231.

[0068] In some other embodiments, the damper 231 includes a rack extending along the damper 231 from the pivot axis 233 toward the other side of the damper 231 opposite the pivot axis 233, with the teeth thereof facing downward. The second drive mechanism includes a first gear 238. The first gear 238 is disposed below the first rack 232 and is configured to disengage from the first rack 232 when the damper 231 moves to the second position, and to engage with the first rack 232 when the damper 231 moves to the first position, driving the damper 231 to translate. The first gear 238 engages with the first rack 232 to control the translation of the damper 231, ensuring relatively stable translation of the damper 231. To distinguish them from the second gear 132 and the second rack 1311 described below, the gear and rack in this embodiment are referred to as the first gear 238 and the first rack 232.

[0069] In some other embodiments, the fresh air device 10 further includes a water washing component 100 and a fan component 300. The water washing component 100 includes a water washing housing 110, a partition 120 and a door assembly. The partition 120 is arranged in the water washing housing 110 to separate the space in the water washing housing 110 into an air duct 111 and a water tank 112, and has a connecting portion 121 that connects the air duct 111 and the water tank 112. The air duct 111 has an air duct outlet 1111 and an air inlet 1112; the water tank 112 has a water tank outlet 1121, which is configured to wash the gas flowing through it. The door assembly is configured to control the outflow of gas from the air duct outlet 1111 and / or the water tank outlet 1121. The filter assembly 200 is arranged at the air inlet 1112, and is used to filter the gas flowing into the water washing housing 110. The fan assembly 300 is configured to force the gas to enter the water washing housing 110 from the air inlet 1112 and flow out from the air duct outlet 1111 and / or the water tank outlet 1121 .

[0070] In this embodiment, the shape of the water washing housing 110 is not specifically limited and can be selected according to needs. Figures 8 to 12 As shown, the shape of the water washing housing 110 is approximately a cube. Obviously, this is only exemplary and not exclusive.

[0071] In this embodiment, the shape of the partition 120 is not specifically limited and can be selected according to needs. For example, the partition 120 can be flat, arc-shaped, or other irregular shapes.

[0072] In this embodiment, the location of the partition 120 in the water washing housing 110 is not specifically limited and can be selected as needed. Figures 8 to 12 As shown, the partition 120 is provided on the bottom wall of the water washing housing 110, and the partition 120 is parallel to the right side wall of the water washing housing 110. The partition 120 divides the water washing housing 110 into two left and right cavities. The left cavity is configured as an air duct 111, and the right cavity is configured as a water tank 112. Obviously, this is only exemplary and not exclusive. For example, the plane where the partition 120 is located intersects with the plane where the right side wall of the water washing housing 110 is located. For example, the partition 120 can be provided on the left side wall of the water washing housing 110, dividing the water washing housing 110 into two upper and lower cavities, the lower cavity is configured as the water tank 112, and the upper cavity is configured as the air duct 111.

[0073] In this embodiment, the specific position of the partition 120 forming the connecting portion 121 is not specifically limited. Figure 9 and Figure 10As shown, the distance between the partition 120 and the top wall of the washing housing 110 forms a connecting portion 121. Obviously, this is merely exemplary and not exclusive. For example, a notch may be provided in the partition 120 to form the connecting portion 121. The connecting portion 121 is used to connect the air duct 111 and the water tank 112.

[0074] In this embodiment, the number of door bodies 131 included in the door assembly is not specifically limited and can be selected as needed. The way in which the door assembly controls the opening and closing of the air duct outlet 1111 and the water tank outlet 1121 is not specifically limited and can be selected as needed. For example, the door assembly can include four door bodies, each used to control the opening and closing of the air inlet 1112, the connecting portion 121, the air duct outlet 1111, and the water tank outlet 1121. The door assembly can control the opening and closing of the air inlet 1112, the connecting portion 121, the air duct outlet 1111, and the water tank outlet 1121 by pushing, pulling, or rotating.

[0075] In this embodiment, the door assembly controls the air to flow out from the air duct outlet 1111 and / or the water tank outlet 1121. Figure 9 As shown, the door assembly controls the air to flow along the air duct 111 and to flow out of the water washing housing 110 from the air duct outlet 1111. And / or, as Figure 10 As shown, the door assembly controls the air to flow along the air duct 111 into the water tank 112 and out of the water washing housing 110 from the water tank air outlet 1121. This allows the fresh air device 10 to freely switch between fresh air water washing and fresh air flowing directly out of the water washing housing 110.

[0076] In this embodiment, the specific structure of the filter assembly 200 is not limited and can be selected according to needs. The filter assembly 200 can filter the gas flowing into the water washing housing 110 through the air inlet 1112. As a specific embodiment, Figures 1 to 10 As shown, the filter assembly 200 includes a filter housing 210, a filter element 220, and a damper assembly, etc. Obviously, this is only exemplary and not exclusive.

[0077] In this embodiment, the filtering function of the filter assembly 200 is not specifically limited and can be selected according to needs. For example, the filter assembly 200 can have one or a combination of dust removal, sterilization, formaldehyde removal or odor removal.

[0078] In this embodiment, the specific location of the fan assembly 300 is not limited and can be selected as needed. As a specific embodiment, the fan assembly 300 is located at the water tank air outlet 1121 and the air duct outlet 1111, which makes the wind force at the air duct outlet 1111 and the water tank air outlet 1121 relatively strong. This allows the fan assembly 300 and the filter assembly 200 to be respectively located at the air inlet 1112 and the air outlet of the water washing housing 110, that is, the fan assembly 300 and the filter assembly 200 are respectively located on both sides of the water washing housing 110. This makes the structure of the fresh air device 10 relatively compact.

[0079] In this embodiment, the type of fan included in the fan assembly 300 is not specifically limited. For example, the fan assembly 300 may include a centrifugal fan 310 or an axial flow fan. As a specific embodiment, Figure 9 and Figure 10 As shown, the fan assembly 300 includes a centrifugal fan 310 .

[0080] As can be seen, the fresh air device 10 of this embodiment can introduce fresh air into the water-washing housing 110 after filtering it through the filter assembly 200. The fresh air device 10 can then discharge the filtered fresh air directly into the room, or wash the fresh air with water before discharging it into the room. This allows the fresh air device 10 to have diverse functions, allowing users to freely switch between them according to their usage environment. Furthermore, the fresh air device 10 can be adapted to different models of air conditioner indoor units, eliminating multiple design, development, and production processes, saving design and manufacturing costs and shortening construction time.

[0081] In some other embodiments, the partition 120 extends from the first sidewall of the water washing housing 110 toward the second sidewall of the water washing housing 110 opposite to the first sidewall of the water washing housing 110 to separate the space in the water washing housing 110 into the air duct 111 and the water tank 112 .

[0082] An area where the second side wall of the washing housing 110 faces the air duct 111 forms an air duct outlet 1111 ; and an area where the second side wall of the washing housing 110 faces the water tank 112 forms a water tank outlet 1121 .

[0083] In this embodiment, the first sidewall of the wash housing 110 is opposite to the second sidewall of the wash housing 110. That is, when the first sidewall of the wash housing 110 is the bottom sidewall, the second sidewall of the wash housing 110 is the top sidewall. When the first sidewall of the wash housing 110 is the left sidewall, the second sidewall of the wash housing 110 is the right sidewall. When the first sidewall of the wash housing 110 is the front sidewall, the second sidewall of the wash housing 110 is the rear sidewall. In a specific embodiment, the first sidewall of the wash housing 110 is the bottom sidewall, and the second sidewall of the wash housing 110 is the top sidewall. A partition 120 extends from the first sidewall of the wash housing 110 toward the second sidewall of the wash housing 110 to separate the space in the wash housing 110 into an air duct 111 and a water tank 112. The second sidewall of the wash housing 110 forms an air duct outlet 1111 and a water tank outlet 1121. The wash housing 110 has an air inlet 1112. This makes the airflow directions of the gas in the air duct 111 and the water tank 112 closer, thereby reducing wind resistance.

[0084] In some other embodiments, the door assembly includes a door 131 , which is configured to slide along the second side wall of the washing housing 110 between the air duct outlet 1111 and the water tank outlet 1121 to open the air duct outlet 1111 or the water tank outlet 1121 .

[0085] The door body 131 slides along the second side wall of the washing housing 110, that is, the door body 131 slides along the top side wall of the washing housing 110. The sliding direction of the door body 131 is the direction of the line connecting the center of the air duct outlet 1111 and the center of the water tank outlet 1121. As a specific embodiment, Figures 9 to 11 As shown, the door body 131 slides in the left-right direction.

[0086] In this embodiment, the specific manner in which the door body 131 slides along the second side wall between the air duct outlet 1111 and the water tank outlet 1121 is not limited and can be selected as needed. Figure 11 As shown, the door body 131 is controlled to slide by the rack and gear. Obviously, this is only exemplary and not exclusive. For example, magnetic adsorption members 234 are provided on the left and right sides of the door body 131, and electromagnetic adsorption members 237 are provided on the left and right sides of the second side wall to control the left and right sliding of the door body 131. This structure of the fresh air device 10 is relatively simple, as shown in FIG. Figures 9 to 12 As shown, the fresh air device 10 can switch between the fresh air and fresh air washing functions by using only one door body 131, that is, the fresh air device 10 can control the gas flow by using only one door body 131. Figure 9 As shown, the air flows out from the air duct outlet 1111 or as shown in FIG. Figure 10 As shown, it flows out from the water tank outlet 1121.

[0087] In some other embodiments, the door assembly further includes a motor, a second gear 132, and a second rack 1311. The second gear 132 is fixedly connected to the output shaft of the motor. The second gear 132 is disposed on a first side of the door 131, extending in a direction consistent with the sliding direction of the door 131, and meshing with the second gear 132 to drive the door 131 to slide.

[0088] In this embodiment, the gear and rack are referred to as the second rack 1311 and the second gear 132, respectively, to distinguish them from the first rack 232 and the first gear 238 described above. The second gear 132 meshes with the second rack 1311 to drive the door 131 to slide. This method is simple and easy to control, and the door 131 slides more smoothly.

[0089] In some other embodiments, the second side wall of the washing shell 110 has a slide groove 113, the extension direction of the slide groove 113 is consistent with the sliding direction of the door body 131, the first side of the door body 131 is arranged in the slide groove 113 so that the door body 131 slides along the slide groove 113, and the second gear 132 extends into the slide groove 113 from the outside of the slide groove 113 and engages with the second rack 1311.

[0090] The slide groove 113 is used to limit the movement trajectory of the door body 131, so that the movement of the door body 131 is relatively stable. The second gear 132 goes deep into the slide groove 113 from the outside of the slide groove 113 and engages with the second rack 1311, that is, Figure 12 As shown, a portion of the second gear 132 extends into the slide groove 113, and the other portion is located outside the slide groove 113, which facilitates the connection between the second gear 132 and the motor and makes the overall structure more beautiful and compact.

[0091] In some other embodiments, the distance between the partition 120 and the second side wall forms a connecting portion 121. This makes the structure of the fresh air device 10 compact and saves space.

[0092] In some other embodiments, the filter assembly 200 includes a filter housing 210 and a filter element 220. The filter housing 210 is disposed at the air inlet 1112, with the second sidewall of the filter housing 210 abutting the air inlet 1112. The second sidewall of the filter housing 210 opposite the air inlet 1112 forms a filter outlet 213 of the filter housing 210. The filter element 220 is disposed within the filter housing 210, upstream of the filter outlet 213, and is configured to filter the gas flowing therefrom to the filter outlet 213.

[0093] As a specific example, Figure 9 and Figure 10As shown, the first sidewall of the water-wash housing 110 refers to the bottom sidewall of the water-wash housing 110. The second sidewall of the filter housing 210 refers to the top sidewall of the filter housing 210. The second sidewall of the filter housing 210 is in contact with the air inlet 1112, and a filtered air outlet 213 is formed at the second sidewall of the filter housing 210 opposite the air inlet 1112. This reduces the resistance to gas flow and ensures smoother gas flow.

[0094] In this embodiment, the specific location of the filter element 220 in the filter housing 210 is not limited and can be selected as needed. The filter element 220 can filter the gas that will flow out of the filter outlet 213, that is, the filter element 220 can filter the gas before it flows out of the filter outlet 213, that is, the gas is first filtered by the filter element 220 and then flows out of the filter outlet 213. For example, the filter element 220 is set parallel to the filter outlet 213, and the filter element 220 is set vertically to the filter outlet 213. As a specific embodiment, Figure 9 and Figure 10 As shown, the filter element 220 is vertically arranged to the filter air outlet 213 .

[0095] In other embodiments, the filter element 220 includes a filter support 221 and one or more of a dust removal filter element 222, a sterilizing filter element 222, a formaldehyde removal filter element 222, and a deodorizing filter element 222. The filter support 221 is push-pull mounted within the filter housing 210. One or more of the dust removal filter element 222, sterilizing filter element 222, formaldehyde removal filter element 222, and deodorizing filter element 222 are removably mounted within the filter support 221. This facilitates replacement and addition / removal of the dust removal filter element 222, sterilizing filter element 222, formaldehyde removal filter element 222, and deodorizing filter element 222, thereby diversifying the types of filtration.

[0096] In some other embodiments, the fan assembly 300 includes a centrifugal fan 310, the inlet of which is arranged at the air duct outlet 1111 and the water tank outlet 1121, for promoting the gas to flow from the filter housing 210 to the water washing housing 110 and be discharged.

[0097] An air inlet 1112 is formed at a position where the first side wall of the water washing housing 110 is opposite to the air duct 111 , which reduces the flow resistance of the gas and makes the flow smoother.
