As shown in fig. 1 to 12, the present embodiment provides a fresh air device 10, the fresh air device 10 includes a filter assembly 200, and the filter assembly 200 includes a filter housing 210, a filter element 220 and a wind valve assembly. Wherein the damper assembly includes a damper 231. The first side wall 216 of the filter housing has a first filter inlet 211 and a second filter inlet 212. The filter member 220 is used to filter the gas flowing into the filter housing 210 from the first filter inlet 211 and/or the second filter inlet 212. The damper 231 is configured to translate in a first direction to open the first filter intake vent 211 or the second filter intake vent 212 when the first sidewall 216 of the filter housing translates in the first direction, to translate in a second direction to switch between a first position and a second position when translated in the first direction to the first position, and to rotate relative to the first sidewall 216 of the filter housing to simultaneously open the first filter intake vent 211 and the second filter intake vent 212 when in the second position.

In the present embodiment, the shape of the filter housing 210 is not limited, and may be selected as needed. For example, the filter housing 210 may be rectangular parallelepiped in shape or other irregular shape. In the present embodiment, the first sidewall 216 of the filter housing may be a front sidewall, a rear sidewall, a right sidewall, a left sidewall, an upper sidewall, or a lower sidewall of the filter housing 210. As a specific example, as shown in fig. 1, the first sidewall 216 of the filter housing is one of a front sidewall, a rear sidewall, a right sidewall, and a left sidewall of the filter housing 210.

In this embodiment, specific applications of the first filtering intake vent 211 and the second filtering intake vent 212 are not limited, and may be selected according to needs. As a specific example, the first filtering air inlet 211 is adapted to communicate with the indoor space, and the second filtering air inlet 212 is adapted to communicate with the outdoor space. This enables the fresh air device 10 to introduce indoor air to mix with outdoor air in advance when introducing outdoor air, thereby preventing the introduced outdoor air from being overcooled or overheated. In this embodiment, the shapes of the first filtering air inlet 211 and the second filtering air inlet 212 are not limited and can be selected as needed.

In this embodiment, the relative positions of the first filtering air inlet 211 and the second filtering air inlet 212 are not limited, and may be selected according to the requirement. As a specific example, as shown in FIG. 1, the centers of the first and second

filtering air inlets

211 and 212 are on the same horizontal plane. It will be clear that this is only exemplary and not exclusive. For example, the center of the first filter intake vent 211 is lower than the center of the second filter intake vent 212, that is, the second filter intake vent 212 is located obliquely above the first filter intake vent 211.

In the present embodiment, the position of the filter member 220 is not particularly limited and may be selected as needed. As a specific example, as shown in fig. 1 and 2, the filter element 220 is disposed within the filter housing 210. It will be clear that this is exemplary only and not exclusive. For example, the filter element 220 is disposed in the first filter inlet 211 and/or the second filter inlet 212.

In the present embodiment, the damper 231 is configured to translate along the first sidewall 216 of the filter housing to open the first filter intake vent 211 or the second filter intake vent 212. The first direction in which the damper 231 translates is not particularly limited and may be selected as desired. As a specific example, as shown in fig. 1, the centers of the first filtering intake vent 211 and the second filtering intake vent 212 are located on the same horizontal plane, and the first direction of the translation of the damper 231 is the horizontal direction to open the first filtering intake vent 211 or the second filtering intake vent 212, which makes the structure of the fresh air device 10 relatively compact. It will be clear that this is exemplary only and not exclusive. For example, the damper 231 may also be translated in an obliquely upward or obliquely upward direction to open the first filtering intake port 211 or the second filtering intake port 212.

In this embodiment, the specific position of the first position is not limited, and may be selected as needed. As a specific example, as shown in fig. 1, when the damper 231 is at the first position, the pivot axis 233 thereof is located at a position intermediate the first filtering air inlet 211 and the second filtering air inlet 212. It will be clear that this is exemplary only and not exclusive.

In the present 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 example, as shown in fig. 1 to 5, the first translation direction is perpendicular to the second translation direction, which is obviously only exemplary and not exclusive.

In some cases, a heating element is disposed at the second filtering air inlet 212 to heat the fresh air in advance. If the damper 231 is directly rotated, structural interference may be formed between the damper 231 and the heating member, thereby preventing the damper 231 from being rotated. The air door 231 of this kind of arrangement can avoid air door 231 to interfere with the structure of other structures, and one air door 231 can make first filtration air intake 211 and second filter air intake 212 possess several kinds of circumstances such as opening alone and opening simultaneously to satisfy several kinds of circumstances such as fresh air device 10 separately enters indoor wind, separately enters outdoor wind and simultaneously enters indoor wind and outdoor wind, make fresh air device 10's function diversified.

In 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 provided 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 is coaxially connected to the pivot shaft 233 to rotate the pivot shaft 233 when the damper 231 is in the second position. The first drive mechanism 236 is used to drive the output shaft 235 to rotate.

In the present embodiment, the extending direction of the pivot 233 is not particularly limited, and may be selected as needed. As a specific example, as shown in fig. 1 to 5, the extending direction of the pivot shaft 233 coincides with the second direction, that is, the pivot shaft 233 is disposed in a vertical direction. It will be apparent that this is merely exemplary and not exclusive. For example, the pivot shaft 233 may be disposed obliquely upward.

In the present 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 identical to the direction of the pivot shaft 233, that is, the output shaft 235 is coaxial with the pivot shaft 233. That is, when the damper 231 is in the second position, both the pivot shaft 233 and the output shaft 235 are in a vertical orientation. The pivot shaft 233 is in an obliquely upward direction, and the output shaft 235 is also in an obliquely upward direction. This enables the output shaft 235 to be coaxially connected with the pivot shaft 233 when the damper 231 is in the second position. As shown in fig. 1 to 5, the pivot shaft 233 is disposed in a vertical direction, and the output shaft 235 is also disposed in a vertical direction, which is obviously merely exemplary and not exclusive.

In the present embodiment, the specific manner of coaxial connection between the output shaft 235 and the pivot shaft 233 is not limited, and can be selected according to the requirement. For example, the output shaft 235 and the pivot shaft 233 are connected by electromagnetic attraction, adhesive connection, vacuum attraction, or the like.

In the present embodiment, when the damper 231 is in the first position, the output shaft 235 is decoupled from the pivot shaft 233, which prevents the output shaft 235 from affecting the translation of the damper 231 in the first direction. When the damper 231 is in the second position, the output shaft 235 is connected to the pivot shaft 233 to rotate the pivot shaft 233.

In other embodiments, the first end of the pivot shaft 233 is provided with a magnetic attraction 234. The output shaft 235 is disposed in the second direction, on which an electromagnetic absorption member 237 is disposed, configured to absorb the pivot shaft 233 thereto in the second direction when the damper 231 is translated to the first position.

In the present embodiment, the output shaft 235 is disposed in the second direction, and the magnetic attraction force between the output shaft 235 and the pivot shaft 233 is used to both connect the output shaft 235 and the pivot shaft 233 and move the pivot shaft 233 and the damper 231 in the second direction. This simple structure makes the structure of new trend device 10 compact.

In some other embodiments, the first direction is a horizontal direction, the second direction is a vertical direction, the output shaft 235 is disposed above the pivot shaft 233, and the pivot shaft 233 is switched between the first position and the second position under the gravity and the driving of the magnetic attraction member 234 and the electromagnetic attraction member 237. This simple, energy-saving and compact construction of the fresh air device 10. It is apparent that this is not the only embodiment, for example, two electromagnetic absorption members 237 are provided on both sides of the pivot shaft 233 to control the switching of the damper 231 between the first position and the second position.

In other embodiments, the filter housing 210 further includes a first recess 214 and a second recess 215. The length direction of the first groove 214 is disposed on the first sidewall 216 of the filter housing along the first direction, and is located on the upper side of the pivot shaft 233, for the first end of the pivot shaft 233 to translate, rotate and switch between the first position and the second position.

The length direction of the second groove 215 is arranged on the first side wall 216 of the filter housing along the first direction, and is located at 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. The fresh air device 10 is simple and compact in structure. It is apparent that the manner in which the damper 231 is translated and rotated by the pivot shaft 233 being disposed in the first and

second recesses

214 and 215 is merely exemplary and not exclusive. For example, first and

second recesses

214 and 215 are located between the upper and lower sides of damper 231, and the respective positions of damper 231 cooperate with first and

second recesses

214 and 215 to effect translation and rotation of damper 231 within first sidewall 216 of filter housing.

In 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 configured to be pressed by the second end of the pivot shaft 233 when the pivot shaft 233 is translated to the first position along the first direction to detect that the pivot shaft 233 is translated to the first position.

In the present embodiment, the sensor assembly 240 may include a pressure sensor or a capacitance 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, and it can be determined 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 exerts pressure on the sensor assembly 240, thereby determining that the damper 231 is out of the first position. This makes the construction of the fresh air device 10 simple and compact.

In other embodiments, the damper assembly further comprises a second drive mechanism. The second drive mechanism is configured to engage the damper 231 to drive the damper 231 to translate in the first direction when the damper 231 is in the first position and disengage the damper 231 when the damper 231 is in the second position.

In this embodiment, the type of the second driving mechanism is not limited, and can be selected as needed. The second drive mechanism may be configured to drive the damper 231 to translate in the first direction. When damper 231 is in the second position, the second drive mechanism is disengaged from damper 231, which prevents the second drive mechanism from affecting the rotation of damper 231.

In other embodiments, the damper 231 has a rack gear extending along the damper 231 from the pivot shaft 233 toward the other side of the damper 231 opposite the pivot shaft 233 with its teeth disposed downward. The second drive mechanism includes a first gear 238. The first gear 238 is disposed below the first rack 232 and configured to disengage from the first rack 232 when the damper 231 moves to the second position, and engage with the first rack 232 to drive the damper 231 to translate when the damper 231 moves to the first position. The first gear 238 engages the first rack 232 to control the damper 231 to translate such that the translation of the damper 231 is relatively stable. The gears and racks in this embodiment are named a first gear 238 and a first rack 232 for the purpose of distinguishing from the second gear 132 and the second rack 1311 described below.

In other embodiments, the fresh air device 10 further includes a water washing assembly 100 and a fan assembly 300. The washing assembly 100 includes a washing housing 110, a partition 120, and a door assembly. The partition plate 120 is provided in the water washing case 110 to partition a space in the water washing case 110 into the air passage 111 and the water tank 112, and has a communication portion 121 that communicates the air passage 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 configured to wash the gas flowing therethrough. The door body assembly is configured to control air to flow out of the air duct outlet 1111 and/or the water tank outlet 1121. The filter assembly 200 is disposed at the air inlet 1112, and is used for filtering the air flowing into the water washing housing 110. The fan assembly 300 is configured to force air from the air inlet 1112 into the water wash housing 110 and out of the air duct outlet 1111 and/or the water tank outlet 1121.

In the present embodiment, the shape of the water washing case 110 is not particularly limited and may be selected as needed. As a specific example, as shown in fig. 8 to 12, the water washing housing 110 is approximately square in shape. It will be clear that this is exemplary only and not exclusive.

In the present embodiment, the shape of the partition 120 is not particularly limited and may be selected as needed. For example, the partition 120 may be flat, circular, or other irregular shape.

In this embodiment, the position of the partition 120 in the water washing case 110 is not particularly limited, and may be selected as needed. As a specific example, as shown in fig. 8 to 12, the partition plate 120 is disposed on the bottom wall of the water washing case 110, the partition plate 120 is parallel to the right side wall of the water washing case 110, and the partition plate 120 divides the water washing case 110 into two left and right cavities. The left cavity is configured as a wind tunnel 111 and the right cavity is configured as a water tank 112. It will be clear that this is exemplary only and not exclusive. For example, the partition 120 is formed on a plane intersecting with a plane of a right side wall of the washing housing 110. For example, the partition 120 may be disposed on a left side wall of the washing housing 110 to divide the washing housing 110 into an upper cavity and a lower cavity, where the lower cavity is configured as the water tank 112 and the upper cavity is configured as the air duct 111.

In the present embodiment, the specific position where the communication portion 121 is formed by the partition 120 is not particularly limited. For example, as shown in fig. 9 and 10, a distance between the partition 120 and the top wall of the water washing case 110 forms a communication portion 121. It will be clear that this is exemplary only and not exclusive. For example, the partition 120 may be notched to form the communication portion 121. The communication portion 121 is for communicating the air duct 111 and the water tank 112.

In this embodiment, the number of the door bodies 131 included in the door body assembly is not specifically limited, and may be selected according to needs. The opening and closing modes of the door body assembly for controlling the air duct outlet 1111 and the water tank outlet 1121 are not particularly limited and can be selected according to the needs. For example, the door assembly may include four doors for controlling the opening and closing of the air inlet 1112, the communication 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 communicating part 121, the air duct outlet 1111 and the water tank outlet 1121 through a push-pull or rotation mode.

In this embodiment, the door assembly controls the air to flow out of the air duct outlet 1111 and/or the water tank outlet 1121. That is, as shown in fig. 9, the door assembly controls the air to flow along the air duct 111 and flow out of the water washing case 110 from the air duct outlet 1111. And/or, as shown in fig. 10, the door assembly controls the air to flow into the water tank 112 along the air duct 111, and flow out of the water washing housing 110 from the water tank outlet 1121. This makes the fresh air device 10 wash the water casing 110 internal flow and the freedom of switching certainly of fresh air direct from the new trend.

In this embodiment, the specific structure of the filter assembly 200 is not limited, and may be selected according to the requirement, and the filter assembly 200 can filter the air flowing into the water washing housing 110 through the air inlet 1112. As a specific example, as shown in fig. 1 to 10, the filter assembly 200 includes a filter housing 210, a filter member 220, a damper assembly, and the like. It will be apparent that this is merely exemplary and not exclusive.

In this embodiment, the filtering function of the filtering assembly 200 is not particularly limited, and may be selected according to the requirement. For example, filter assembly 200 may be provided with one or a combination of dust removal, bacteria removal, aldehyde removal, or odor removal.

In this embodiment, the specific setting position of the fan assembly 300 is not limited, and can be selected according to the requirement. As a specific example, the fan assembly 300 is disposed at the water tank outlet 1121 and the air duct outlet 1111, which makes the wind force at the air duct outlet 1111 and the water tank outlet 1121 stronger. This allows the fan assembly 300 and the filter assembly 200 to be disposed at the air inlet 1112 and the air outlet of the washing housing 110, respectively, that is, the fan assembly 300 and the filter assembly 200 are disposed at both sides of the washing housing 110, respectively. This makes the structure of the fresh air device 10 relatively compact.

In the present embodiment, the type of the fan included in the fan assembly 300 is not particularly limited, and for example, the fan assembly 300 may include a centrifugal fan 310 or an axial flow fan. As a specific example, as shown in fig. 9 and 10, the fan assembly 300 includes a centrifugal fan 310.

Therefore, the fresh air device 10 of the embodiment can filter the fresh air through the filter assembly 200 and then introduce the fresh air into the washing shell 110, and the fresh air device 10 can directly discharge the filtered fresh air into the room or discharge the fresh air into the room after washing. This diversifies the functions of the fresh air device 10, and allows the user to freely switch between the functions according to the use environment. Meanwhile, the fresh air device 10 can be suitable for air conditioner indoor units of different types, so that repeated design, development and production are avoided, the design and manufacturing cost is saved, and the construction period is shortened.

In other embodiments, the partition 120 extends from a first sidewall of the water washing case 110 toward a second sidewall of the water washing case 110 opposite to the first sidewall of the water washing case 110 to partition the space inside the water washing case 110 into the wind tunnel 111 and the water tank 112.

An air duct air outlet 1111 is formed in a region, opposite to the air duct 111, of the second side wall of the washing shell 110; a region of the second sidewall of the washing housing 110 opposite to the water tank 112 forms a water tank outlet 1121.

In the present embodiment, the first sidewall of the water washing case 110 is opposite to the second sidewall of the water washing case 110, that is, when the first sidewall of the water washing case 110 is a bottom sidewall, the second sidewall of the water washing case 110 is a top sidewall. When the first sidewall of the washing case 110 is a left sidewall, the second sidewall of the washing case 110 is a right sidewall.
