An air duct member 100 for an air conditioner 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 1 and 2, an air duct assembly 100 for an air conditioner 1000 according to an embodiment of the present invention may include a first assembly 10, where the first assembly 10 includes an air duct casing assembly 1, a first air-out frame 2, and a second air-out frame 3.
As shown in fig. 1, a first air supply duct 11 and a second air supply duct 12 are defined in the duct case group 1, the first air supply duct 11 includes an upstream duct chamber 111 and a downstream duct chamber 112 disposed above the upstream duct chamber 111, the air supply of the first air supply duct 11 flows from the upstream duct chamber 111 to the downstream duct chamber 112 from bottom to top, the second air supply duct 12 is disposed in the downstream duct chamber 112, the second air supply duct 12 extends in the front-rear direction (refer to fig. 2), and the second air supply duct 12 supplies air in the front-rear direction. For example, referring to fig. 5, a centrifugal wind wheel 5 is provided in the upstream air duct chamber 111, an axial flow wind wheel 6 is provided in the second supply air duct 12, and the air supply direction of the upstream air duct chamber 111 to the downstream air duct chamber 112 is perpendicular to the air supply direction of the second supply air duct 12.
As shown in fig. 2, the first air-out frame 2 is disposed in front of the air duct shell assembly 1 and is opposite to the downstream air duct cavity 112 in front and back direction, and the second air-out frame 3 is disposed above the air duct shell assembly 1. It should be noted that a portion of the second air supply duct 12 that faces the first air outlet frame 2 in the front-rear direction is a downstream duct cavity 112, and a portion of the second air supply duct 12 other than the downstream duct cavity 112 is an upstream duct cavity 111.
As shown in fig. 10, the air duct member 100 is structured such that a part of the air supplied from the downstream air duct cavity 112 flows forward to the first air outlet frame 2, another part flows upward to the second air outlet frame 3 (air duct flow path shown by a single arrow in fig. 10), and the whole air supplied from the second air supply duct 12 flows forward from the rear to the first air outlet frame 2 (air flow path shown by a double arrow in fig. 10). Therefore, the air flow in the first air supply duct 11 can flow from the upstream air duct cavity 111 to the downstream air duct cavity 112, one part of the air flow in the downstream air duct cavity 112 flows to the first air outlet frame 2, the other part of the air flow flows to the second air outlet frame 3, and the air flow in the second air supply duct 12 only flows to the first air outlet frame 2 and does not flow to the second air outlet frame 3.
Therefore, only the first air supply duct 11 provides air flow to the second air outlet frame 3, and the second air supply duct 12 does not supply air to the second air outlet frame 3, so that the problem that the second air supply duct 12 interferes with the air supply of the first air supply duct 11 to the second air outlet frame 3 and the problem that the first air supply duct 11 interferes with the air supply of the second air supply duct 12 to the first air outlet frame 2 due to the fact that the air supply directions of the first air supply duct 11 and the second air supply duct 12 are different can be avoided.
As shown in fig. 1, a wind-guiding ring 13 is disposed in the wind duct case set 1, a rear end of the wind-guiding ring 13 is connected to the wind duct case set 1, and a wind inlet end (refer to fig. 2) of the second wind-supplying wind duct 12 is defined by a rear end of the wind-guiding ring 13, an avoiding section 131 is disposed on the wind-guiding ring 13, an outer peripheral surface of the avoiding section 131 is formed as a plane (refer to fig. 1) or an arc-shaped surface (refer to fig. 4) protruding toward a side wall far from the downstream wind duct cavity 112, so that the avoiding section 131 does not protrude toward a direction far from a center of the second wind-supplying wind duct 12, an avoiding channel 1311 is defined between the outer peripheral surface of the avoiding section 131 and the side wall of the downstream wind duct cavity 112.
It should be noted that the airflow in the upstream air duct cavity 111 needs to flow to the second air outlet frame 3 by bypassing the outer peripheral wall of the second air supply duct 12, while the cross section of the air guide ring 13 in the related art, which is perpendicular to the central axis of the air guide ring 13, is formed into a circular shape, and the air resistance of the airflow in the upstream air duct cavity 111 in the flowing process of bypassing the second air supply duct 12 upwards is large, which results in a small upward air supply amount of the first air supply duct 11.
According to the air duct component 100 for the air conditioner 1000 in the embodiment of the present invention, the air guide ring 13 is provided with the avoiding section 131 that does not protrude toward the direction away from the center of the second air supply duct 12, so that in the process that the airflow in the upstream duct cavity 111 bypasses the second air supply duct 12 upwards, because the flow passing area of the avoiding channel 1311 is large, the wind resistance of the airflow in the upstream duct cavity 111 when passing through the avoiding channel 1311 is small, which is beneficial to improving the upward air supply amount of the first air supply duct 11, reducing noise, and improving the use experience of the user.
For example, as shown in fig. 1, the second supply air duct 12 may be located at a center position in the left-right direction in the downstream air duct chamber 112, a left ventilation channel 14 may be formed between a left side surface of the second supply air duct 12 and a left wall of the downstream air duct chamber 112, a right ventilation channel 15 may be formed between a right side surface of the second supply air duct 12 and a right wall of the downstream air duct chamber 112, and the air flow in the upstream air duct chamber 111 may flow upward around the second supply air duct 12 from the left and right sides to the second air outlet frame 3 through the left ventilation channel 14 and the right ventilation channel 15. Therefore, the air can be simply and effectively supplied to the second air outlet frame 3 by the downstream air duct cavity 112 without affecting the air outlet of the second air supply duct 12, and meanwhile, the upward air supply amount of the first air supply duct 11 is favorably increased.
Optionally, as shown in fig. 1, there are two avoidance sections 131, and the two avoidance sections 131 are respectively formed at the left and right sides of the wind guide ring 13. For example, the bypass sections 131 are formed on part of the left side surface and part of the right side surface of the second air supply duct 12, which are formed by the air guide ring 13, a left bypass channel 141 and a right bypass channel 151 are respectively defined between the outer peripheral surface of each bypass section 131 and the left and right side walls of the downstream duct cavity 112, the left bypass channel 141 forms a part of the left ventilation channel 14, and the right bypass channel 151 forms a part of the right ventilation channel 15. From this, all set up the section 131 of dodging through the left and right sides at wind-guiding circle 13, can further reduce the windage of the air current in upper reaches wind channel chamber 111 when bypassing second air supply wind channel 12 and flowing to second air-out frame 3, be favorable to improving the ascending air supply volume in first air supply wind channel 11, smallpox air current effect is better to improve user's use and experience.
In some embodiments of the invention, as illustrated with reference to fig. 1 and 3, the cross-sectional area of the bypass channel 1311 remains constant in the bottom-up direction. For example, as shown in fig. 1, two segments are formed on the left and right sides of the wind-guiding ring 13, the outer peripheral surface of each escape segment 131 is formed as a plane, the portions of the left and right side walls of the downstream duct chamber 112 opposite to the two escape segments 131 are formed as planes parallel to the escape segments 131, and the cross-sectional area of the escape passage 1311 is kept constant in the direction from the bottom to the top. Therefore, the wind resistance of the air flow in the upstream air duct cavity 111 when the air flow bypasses the second air supply duct 12 and flows to the second air outlet frame 3 can be further reduced, and the upward air supply quantity of the first air supply duct 11 is favorably improved, so that the use experience of a user is improved.
Further, as shown in fig. 1, the outline of the cross section of the air-guiding ring 13 perpendicular to the central axis of the air-guiding ring 13 includes: the first arc line segment 132, the first straight line segment 133, the second arc line segment 134 and the second straight line segment 135 are connected in sequence, the second straight line segment 135 is connected with the first arc line segment 132, and the first straight line segment 133 and the second straight line segment 135 extend in the up-and-down direction respectively. For example, the cross-sections of the first arc segment 132 and the second arc segment 134 are each formed as a circular arc. Therefore, the air resistance of the air flow in the upstream air duct cavity 111 when the air flow bypasses the second air supply duct 12 and flows to the second air outlet frame 3 can be reduced while the air inlet volume of the air guide ring 13 is ensured, and the upward air supply volume of the first air supply duct 11 is favorably improved, so that the use experience of a user is improved. Of course, the present invention is not limited thereto, and for example, the outer contour of the wind guide ring 13 may also be formed in an oval shape or a square shape.
In some embodiments of the present invention, the flow area of the air guiding ring 13 gradually decreases in the flow direction of the air flow in the second air supply duct 12. For example, as shown in fig. 2, the cylindrical wall of the air guide ring 13 is formed in a substantially circular truncated cone shape, the two escape sections 131 are formed in a flat plate shape and are respectively positioned on the left and right sides of the air guide ring 13, and the portion of the air guide ring 13 excluding the escape sections 131 extends in a direction close to the central axis of the air guide ring 13 in the flow direction of the air flow in the second air blowing duct 12.
It can be understood that, by gradually reducing the flow area of the air guiding ring 13 in the flow direction of the air flow in the second air supply duct 12, the impact of the air flow on the inner wall of the air guiding ring 13 can be reduced, which is beneficial to reducing the noise value, meanwhile, on the basis of the above conditions, the avoidance section 131 is arranged on the air guide ring 13, so that the frequency spectrum of the inlet airflow of the air guide ring 13 generates a specific phase difference, which is beneficial to further reducing the noise, specifically, when the wind wheel in the second air supply duct 12 runs, the air inlet speed and direction of the airflow flowing to the air guide ring 13 are not uniformly distributed along the circumferential direction, therefore, there is a relative time difference when the air flow entering through different positions of the air guiding ring 13 reaches the axial flow wind wheel 6 in the second air supply duct 12, the deviation generated on the time axis is a specific phase difference, which is advantageous for further reducing the noise in the second supply air duct 12.
In some embodiments of the present invention, referring to fig. 5, 6, and 7, the air duct component 100 further includes a stationary guide vane 4, a plurality of first connecting portions 421 are disposed on the stationary guide vane 4, the plurality of first connecting portions 421 are disposed at intervals in the circumferential direction of the stationary guide vane 4, and a second connecting portion 136 matched with the first connecting portions 421 is disposed on the air guide ring 13.
For example, as shown in FIG. 5, as shown in fig. 6 and 7, the air duct casing set 1 includes a front casing 1a and a rear casing 1b, one sides of the front casing 1a and the rear casing 1b facing each other are both open, the front casing 1a and the rear casing 1b are connected in a splicing manner, the air guide ring 13 and the rear casing 1b are an integral molding, the static guide vane 4 is located in the air duct casing set 1, the static guide vane 4 includes a main body portion 41 and an air duct section 42, a plurality of air passing holes are formed in the main body portion 41, one end of the air duct section 42 is connected to the outer periphery of the main body portion 41, the other section of the air duct section 42 is connected to an air outlet end of the air guide ring 13, the air guide ring 13 and the air duct section 42 jointly define the second air supply duct 12, a plurality of first connecting portions 421 are formed on the outer periphery wall of the air duct section 42, and a plurality of second connecting portions 136 matched with the first connecting portions 421 are formed on. Therefore, the reliability of connection between the air guide ring 13 and the static guide vane 4 is improved, and air leakage between the air guide ring 13 and the static guide vane 4 is prevented.
In some embodiments of the present invention, referring to fig. 6 and 7, the first connecting portion 421 is provided with a first positioning member 4211 and a first screw hole 4212, and the second connecting portion 136 is provided with a second positioning member 1361 matched with the first positioning member 4211 and a second screw hole 1362 corresponding to the first screw hole 4212. For example, as shown in fig. 6 and 7, the first positioning member 4211 is formed as one of a positioning hole and a positioning column, and the second positioning member 1361 is formed as the other of the positioning hole and the positioning column, wherein the positioning column may be formed as a double cross rib or a cross rib structure, which is beneficial to improving the reliability of the fit between the first positioning member 4211 and the second positioning member 1361.
