It should be noted that the fresh air assembly 100 provided in the embodiment of the present application is suitable for a fresh air blower (not shown) or a fresh air conditioner (not shown). The fan module 120 includes a wind wheel 121, a rotation motor 122, and a volute 130, and the air duct housing 110 and the volute 130 are sequentially communicated. The volute 130 may be composed of two volute housings 131, and the wind wheel 121 and the rotation motor 122 are installed in the volute 130.
The air duct cavity 111 is formed in the air duct housing 110, the volute 130 is internally provided with an air supply cavity 132 and an air outlet cavity 133, and the wind wheel 121 and the rotating motor 122 are positioned in the air supply cavity 132; the air duct cavity 111, the air supply cavity 132 and the air outlet cavity 133 can be communicated in sequence; the fresh air inlet 112, the exhaust air outlet and the return air inlet 113 are arranged on the air duct shell 110 and are all communicated with the air duct cavity 111, and the air outlet 134 is arranged on the volute 130 and is communicated with the air outlet cavity 133.
It should be noted that the air inlet direction of the fan module 120 is the direction in which air flows from the air duct cavity 111 to the air blowing cavity 132; that is, the pre-diaphragm 200 and the switching damper 300 are located on the path through which air flows, which may block a portion of the air.
The air duct shell 110 communicated with the fan module 120 is arranged, and the pre-partition plate 200 and the switching air door 300 are arranged in the air duct shell 110; when the fresh air module 100 starts a fresh air mode, outdoor fresh air enters the air duct cavity 111 from the fresh air inlet 112, enters the fan module 120, and is finally discharged indoors from the air outlet 134; when the fresh air assembly 100 starts the air exhaust mode, indoor dirty air enters the air duct cavity 111 from the air return opening 113, enters the fan module 120, enters the movable air exhaust air duct 340 from the air exhaust opening 114, and is finally exhausted to the outside from the fresh air opening 112. Because the switching damper 300 is located in the fixed exhaust duct 230 in the retracted state, that is, on the orthographic projection of the plane perpendicular to the air inlet direction of the fan module 120, the projection area of the switching damper 300 is located in the projection area of the pre-partition board 200; when the air exhaust duct is arranged in the original air inlet cavity (namely the duct cavity 111), the occupied area of the air exhaust duct in the original air inlet cavity is reduced, and the air inlet volume of the fresh air component 100 in a fresh air mode is increased.
In addition, because the switching damper 300 is located in the fixed exhaust air duct 230 in the retracted state, the distance between the switching damper 300 and the fresh air inlet 112 is increased, so that air enters the air duct cavity 111 from the fresh air inlet 112 and has a larger flow space, thereby effectively avoiding the generation of internal turbulence, reducing the working noise of the fresh air assembly 100 in a fresh air mode, and reducing the air volume loss.
In some embodiments, the switching damper 300 is rotatably mounted on the pre-partition board 200, the pre-partition board 200 includes a first baffle 210 and a second baffle 220 at an angle, the switching damper 300 includes a third baffle 310 and a fourth baffle 320 at an angle, the third baffle 310 is parallel to the first baffle 210; when the switching damper 300 is in the retracted state, on an orthographic projection of the plane of the first shutter 210, the projection area of the third shutter 310 is located within the projection area of the first shutter 210, and the fourth shutter 320 covers the opening 231; when the switching damper 300 is in the extended state, on the orthographic projection of the plane of the first baffle 210, the projection area of the third baffle 310 partially overlaps with the projection area of the first baffle 210, and one ends of the third baffle 310 and the fourth baffle 320 far away from the air outlet 114 abut against the fresh air opening 112.
The pre-partition 200 and the switching damper 300 are both formed by combining two mutually connected baffles, i.e. L-shaped plates, and the third baffle 310 is parallel to the first baffle 210; the L-shaped plate and the inner wall of the air duct housing 110 may enclose to form a passage with openings 231 at two ends, wherein the pre-partition plate 200 and the inner wall of the air duct housing 110 enclose to form a fixed exhaust air duct 230, one end of the fixed exhaust air duct 230 is communicated with the exhaust port 114, and the other end forms the opening 231 extending into the air duct cavity 111, that is, the fixed exhaust air duct 230 is equivalent to the connecting air duct extending further in the air duct cavity 111; when the switching damper 300 is rotated to an extended state and forms the movable exhaust duct 340 by enclosing with the inner wall of the housing, the movable exhaust duct 340 further extends the fixed exhaust duct 230 and makes the fresh air opening 112 communicate with the exhaust opening 114.
Specifically, the fourth shutter 320 is rotatably installed on the second shutter 220.
That is, the fourth barrier 320 rotates around the edge adjacent to the second barrier 220 as the rotation center, and the length of the edge adjacent to the fourth barrier 320 and the second barrier 220 is longer, so that the connection stability between the fourth barrier 320 and the second barrier 220 can be improved.
Further, in other embodiments, the fourth flap 320 rotates on the first flap 210, or the third flap 310 rotates on the first flap 210, etc., without being limited thereto.
Referring to fig. 1 to 3 and fig. 4a, in some embodiments, the opening 231 is disposed opposite to the fresh air inlet 112.
When the switching damper 300 is in the extended state, the opening 231 communicates with the fresh air port 112; by arranging the opening 231 opposite to the fresh air inlet 112, indoor dirty air can smoothly flow from the fixed exhaust air duct 230 to the movable exhaust air duct 340, and the exhaust efficiency of the fresh air assembly 100 is improved.
Referring to fig. 1 to 3 and fig. 4b, in some embodiments, the fresh air opening 112 is disposed at one side of the opening 231, and an included angle between a plane of the fresh air opening 112 and a plane of the opening 231 is a, where a satisfies: a is more than or equal to 90 degrees and less than 180 degrees.
It can be understood that the extending direction of the fresh air opening 112 is the flow direction of the fresh air entering the air duct cavity 111, that is, the flow direction of the fresh air entering the air duct cavity 111 is perpendicular to the plane of the fresh air opening 112.
By arranging the opening 231 at a side close to the fresh air opening 112 and setting the included angle between the planes of the two openings as A. That is, unlike the structure shown in fig. 4a, the structure in the embodiment of the present application is as shown in fig. 4b, the pre-partition board 200 is disposed on the side of the air duct cavity 111 close to the fresh air inlet 112 (the structure shown in fig. 4a is that the pre-partition board 200 is disposed on the side of the air duct cavity 111 far from the fresh air inlet 112, that is, the fresh air inlet 112 is disposed opposite to the opening 231), and meanwhile, the characteristics of the switching damper 300, the exhaust outlet 114, the return air inlet 113, and the like also follow the position adjustment of the pre-partition board 200. When the switching damper 300 is in the contracted state, the switching damper 300 closes the opening 231, but the switching damper 300 is not located on the path blocking the fresh air from entering, so that the opening 231 of the switching damper 300 has little obstruction to the air flow entering through the fresh air port 112, and the fresh air inlet volume of the fresh air assembly 100 is increased.
Preferably, a is 90 °.
In some embodiments, the first baffle 210 is perpendicular to the second baffle 220; and/or the third baffle 310 is perpendicular to the fourth baffle 320.
For ease of understanding, the first barrier 210 and the third barrier 310 are both referred to as parallel plates, and the second barrier 220 and the fourth barrier 320 are vertical plates.
Further, in other embodiments, the included angle between the first baffle 210 and the second baffle 220 may be appropriately selected as needed, and the included angle between the third baffle 310 and the fourth baffle 320 may also be appropriately selected as needed; such as 60 deg., 120 deg., etc., and are not intended to be unduly limited herein.
Referring to fig. 1 to 5, when the switching damper 300 is in the retracted state, the third baffle 310 rotates into the fixed exhaust duct 230, and the projection area of the third baffle 310 is located in the projection area of the first baffle 210, i.e. the two parallel plates overlap each other; and at this time, the fourth shutter 320 rotates to the opening 231 and closes the opening 231. That is, two vertical plates, one parallel plate and the side wall of the duct housing 110 enclose to form a fixed exhaust duct 230, one end of the fixed exhaust duct 230 is communicated with the exhaust port 114, and the other end opening 231 is sealed, so that the airflow cannot flow in the fixed exhaust duct 230.
Referring to fig. 1 to 3 and 5 to 6, when the switching damper 300 is in the extended state, the third baffle 310 rotates to the outside of the fixed exhaust duct 230, and the projection area of the third baffle 310 partially overlaps with the projection area of the first baffle 210, i.e. the two parallel plates are disposed adjacently; at this time, the fourth baffle 320 rotates to a position where one end abuts against the fresh air port 112, and forms a movable air exhaust duct 340 with the inner wall of the duct shell 110, two ends of the movable air exhaust duct 340 are communicated with the opening 231 and the fresh air port 112, which is equivalent to further extending the fixed air exhaust duct 230 to the fresh air port 112, so that the air flow in the air outlet cavity 133 can sequentially flow through the air outlet 114, the fixed air exhaust duct 230 and the movable air exhaust duct 340, and finally flows out from the fresh air port 112.
Preferably, the first baffle 210 is perpendicular to the second baffle 220, and the third baffle 310 is perpendicular to the fourth baffle 320.
That is, the second baffle plate 220 and the fourth baffle plate 320 are perpendicular to the first baffle plate 210 or the third baffle plate 310; when the switching damper 300 rotates, the side edge of the fourth baffle 320 can be continuously and stably attached to the side edge of the adjacent second baffle 220, so that the tightness between the switching damper 300 and the pre-partition board 200 is improved.
In some embodiments, the duct housing 110 is enclosed by side panels and a bottom panel, the bottom panel having an arc-shaped portion extending from the second baffle 220 to the fresh air opening 112; the third baffle 310 is a sector plate, and the arc-shaped edge of the sector plate abuts against the arc-shaped portion.
It should be noted that the sector plate includes an arc-shaped edge and a linear edge, both ends of the linear edge extend to the arc-shaped edge and the circle center respectively, and distances from each point on the arc-shaped edge to the circle center are equal.
By setting the third baffle 310 as a sector plate, and the arc-shaped edge abuts against the arc-shaped portion, when the switching baffle is rotating, each point of the arc-shaped edge abuts against the arc-shaped edge. Thus, the fixed exhaust duct 230 can be closed or opened only by simply rotating and matching the switching damper 300 and the pre-partition 200, and the tightness of the movable exhaust duct 340 can be improved.
Further, in other embodiments, the bottom plate may be a circular plate, which is not limited herein.
In some embodiments, the fresh air component 100 includes a limiting baffle 400, the limiting baffle 400 is perpendicular to the first baffle 210, one end of the limiting baffle 400 is connected to the pre-partition plate 200, and the other end extends to the air inlet; when the switching damper 300 is in the extended state, the fourth shutter 320 abuts against the limit shutter 400.
By installing the limit baffle 400 in the air duct cavity 111, the switching damper 300 can only rotate to the maximum extent to abut against the limit baffle 400; it is possible to effectively prevent the switching damper 300 from being rotated by an excessively large angle, and thus a gap may occur between the first baffle 210 and the third baffle 310. Air leakage of the movable air exhaust duct 340 and the fixed air exhaust duct 230 is avoided, and the air exhaust efficiency of the fresh air assembly 100 is ensured.
Referring to fig. 1 to 3 and 5 to 8, in some embodiments, the limiting baffle 400 is provided with a vent 410; when the switching damper 300 is in the extended state, the projected area of the vent hole 410 is located within the projected area of the fourth shutter 320 on the orthographic projection of the fourth shutter 320 on the plane.
It should be noted that, when the fresh air module 100 is in the fresh air mode and the switching damper 300 is in the retracted state, the area where the limit baffle 400 is located may pass through the fresh air, and the plate body of the limit baffle 400 may block a part of the air flow from flowing in all directions.
The limiting baffle 400 is provided with a vent hole 410, and the area of the vent hole 410 is smaller than that of the fourth baffle 320. The limit baffle 400 can limit the rotation of the fourth baffle 320, improve the efficiency of the airflow passing through the limit baffle 400, and improve the air intake of the fresh air component 100.

Therefore, in the orthographic projection of the plane where the first baffle 210 is located, the first baffle 210 is a plane, and the second baffle 220 and the limiting baffle 400 are a straight line. When the included angle between the limiting baffle 400 and the second baffle 220 is 120 °, the included angles between the "straight line" of the limiting baffle 400 and the two adjacent sides of the "plane" of the first baffle 210 are both 120 °, and the included angle between the "straight line" of the limiting baffle 400 and the "straight line" of the second baffle 220 is also 120 °. That is, in the orthographic projection of the plane where the first baffle 210 is located, the limiting baffle 400 and the pre-partition plate 200 are arranged in a three-pointed star shape, and according to the triangular stability principle, the structural strength of the air duct shell 110 can be improved.

It should be noted that, during the rotation of the switching damper 300, the second shutter 220 abuts against the fourth shutter 320, and it can be considered that the fourth shutter 320 rotates around the side edge of the second shutter 220. Due to errors in the manufacturing or assembling process, a gap may exist between the second baffle 220 and the fourth baffle 320, and thus a phenomenon of air leakage may occur.
By arranging the sealing strip between the second baffle 220 and the fourth baffle 320, the air leakage phenomenon between the second baffle 220 and the fourth baffle 320 can be effectively avoided.
