[0045] Figure 1 is a schematic structural diagram of an air duct assembly according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figure 2-5 The embodiment of the utility model provides an air duct assembly of an air conditioner cabinet, wherein the air duct assembly 100 includes a wind wheel 110 , a fixed end plate 130 , and a bearing mounting seat 140 protruding upward from the upper surface of the end plate 130 .

[0046] The wind wheel 110 is rotatably disposed in the air duct 300 of the air conditioning cabinet along the vertical direction, and a bearing 120 is coaxially disposed on the upper end of the wind wheel 110 .

[0047] The end plate 130 is disposed horizontally, and the bottom surface of the end plate 130 forms the top surface of the air duct 300 .

[0048] The bearing mounting seat 140 includes a mounting through hole 141 and a limiting structure 142. The mounting through hole 141 passes downward through the end plate 130. The bearing 120 is fixedly connected in the mounting through hole 141. The limiting structure 142 is arranged on the hole wall of the mounting through hole 141 to limit the bearing 120 in the vertical direction.

[0049] The end plate 130 and the bearing mounting seat 140 are integrally formed.

[0050] The air conditioner cabinet is usually placed or installed vertically, and a vertically arranged air duct frame is formed in the shell, and the edges of the air duct 300 are limited in the air duct frame.

[0051] In this embodiment, the end plate 130 is a part of the air duct frame, or the end plate 130 is integrally formed with the air duct frame. The end plate 130 is located at the upper part of the air duct frame, and the bottom surface of the end plate 130 forms the top surface of the air duct 300. Correspondingly, a bottom plate opposite to the end plate 130 is usually provided at the lower part of the air duct frame to form the bottom surface of the air duct 300.

[0052] The wind wheel 110 may be a crossflow wind wheel, an axial flow wind wheel, etc., and is rotatably arranged around a vertical axis in the wind duct 300. Specifically, a rotating shaft at one end of the wind wheel 110 may be mounted on the end plate 130 or the bottom plate through a bearing 120, and a rotating shaft at the other end of the wind wheel 110 may be connected to a motor and mounted on the bottom plate or the end plate 130 through the motor. The bearing 120 may generally be an oil-containing bearing to reduce rotational friction and reduce operating noise.

[0053] In this embodiment, the upper rotating shaft of the wind wheel 110 is installed on the end plate 130 through the bearing 120, and the lower end of the wind wheel 110 is connected to the motor and installed on the bottom plate. In this way, the overall center of gravity of the air-conditioning cabinet can be lowered and the stability of the placement or installation of the air-conditioning cabinet can be improved.

[0054] Specifically, the air duct assembly 100 of the utility model has a bearing mounting seat 140 integrally formed on the end plate 130, and a mounting through hole 141 is provided on the bearing mounting seat 140. The upper end of the mounting through hole 141 penetrates the bearing mounting seat 140 to form the top of the mounting through hole 141. The lower end of the mounting through hole 141 penetrates the end plate 130 to connect the air duct 300.

[0055] The bearing 120 is inserted and installed in the installation through hole 141 along the axial direction, and at least part of the peripheral wall of the bearing 120 is fitted with the inner wall of the installation through hole 141 to form a clearance fit or an interference fit. Preferably, part of the peripheral wall of the bearing 120 is made of plastic, rubber or other materials, and forms an interference fit with the inner wall of the installation through hole 141, so that the bearing 120 is firmly installed in the bearing mounting seat 140, avoiding relative sliding between the bearing 120 and the bearing mounting seat 140, and reducing the shaking and noise of the wind wheel 110 during operation.

[0056] The shape of the mounting through hole 141 can be set according to the shape of the bearing 120. For example, if the shape of the bearing 120 is square or circular, the mounting through hole 141 is also correspondingly set to be square or circular, which will not be repeated here.

[0057] In this embodiment, a limiting structure 142 is provided on the hole wall of the installation through hole 141, which can limit the bearing 120 in the axial direction to prevent the bearing 120 from being separated from the installation through hole 141. The limiting structure 142 can be a buckle structure, a groove, a convex rib, etc., which cooperates with the peripheral wall of the bearing 120 to limit the bearing 120 in the axial direction to prevent the bearing 120 from being separated from the installation through hole 141 downward or passing through the installation through hole 141 upward.

[0058] Compared with the prior art, the technical solution of the utility model involves fewer parts, which can improve assembly accuracy, simplify assembly process and reduce manufacturing costs.

[0059] On the other hand, the bearing mounting seat 140 of the utility model is integrally formed on the upper surface of the end plate 130 and protrudes upward. That is to say, no assembly gap will be generated at the connection between the bearing mounting seat 140 and the end plate 130, which can prevent water, impurities, etc. on the upper surface of the end plate 130 from entering the mounting through hole 141 and will not enter the bearing 120, thereby avoiding affecting the service life of the bearing 120.

[0060] On the other hand, since the upper end of the mounting through hole 141 passes through the bearing mounting seat 140, the user or maintenance personnel can conveniently observe the condition of the bearing 120 from the upper side to determine whether the bearing 120 is normal. The maintenance personnel can also conveniently add lubricant to the oil-containing bearing from the upper side without disassembling the bearing 120.

[0061] In some embodiments of the air duct assembly of the present utility model, as Figure 1 and Figure 5 As shown, the air duct assembly 100 forms a plurality of air ducts 300, and the plurality of air ducts 300 are arranged at intervals in the transverse direction. The wind wheels 110 and the end plates 130 are arranged in a plurality corresponding to each of the air ducts 300.

[0062] There are at least two end plates 130 whose bottom surfaces are at different heights.

[0063] Figure 1 The air duct assembly 100 is shown to form two left and right air ducts 300, the two air ducts 300 are arranged at intervals, and two wind wheels 110 can be arranged to increase the air volume of the air conditioner cabinet and expand the air outlet mode to adapt to different application scenarios. In other embodiments of the utility model, the air duct assembly 100 can also form multiple air ducts 300 arranged horizontally.

[0064] In this embodiment, Figure 5 As shown, the bottom surfaces of the end plates 130 of the two air ducts 300 are at different heights. In other words, the top surfaces of the two air ducts 300 are formed with steps. With such a configuration, bearings 120 of different specifications can be installed, and wind wheels 110 of different lengths and positions can be installed, thereby meeting the application scenarios of different wind wheels 110 and expanding the air outlet mode of the air conditioner cabinet.

[0065] Exemplarily, a longer wind wheel 110 may be provided in the left wind duct 300 , and a shorter wind wheel 110 may be provided in the right wind duct 300 , so as to increase the air volume output to the left side space of the air conditioning hub.

[0066] Exemplarily, wind wheels 110 of the same length may be provided in the two air ducts 300, but the wind wheel 110 of the left air duct 300 is positioned higher, while the wind wheel 110 of the right air duct 300 is positioned lower, so that an air outlet height difference is formed on the left and right sides of the air conditioning hub, thereby improving the air outlet effect.

[0067] In particular, the two air ducts 300 may also use the same wind wheel 110, and by setting different height differences on the bottom surfaces of the end plates 130, a foolproof effect of the two wind wheels 110 during the assembly process is achieved.

[0068] In some embodiments of the air duct assembly of the present utility model, as Figure 5 As shown, the top surfaces of the end plates 130 are at the same height. That is, the thickness of the end plates 130 can be adjusted so that the top surfaces of the end plates 130 are at the same height to maintain the consistency of the height of the upper end of the air duct assembly 100.

[0069] In some embodiments of the air duct assembly of the present utility model, as Figure 5 As shown, the top ends of the mounting through holes 141 are at the same height.

[0070] In this embodiment, the thickness of the end plate 130 or the thickness of the bearing mounting seat 140 can be adjusted so that the tops of the mounting holes 141 are flush when the bottom surfaces are uneven, thereby maintaining the consistency of the height of the upper end of the air duct assembly 100.

[0071] In some embodiments of the air duct assembly of the present utility model, as Figure 4 As shown, the bearing 120 is a rotating body. The mounting through hole 141 is a circular hole and is coaxial with the bearing 120.

[0072] The bearing 120 is a rotating body, which can save material cost and does not need to distinguish the circumferential angle during installation, which is convenient for installation. At the same time, it can also save material for the bearing mounting seat 140, and make the stress of the bearing mounting seat 140 uniform after forming, and the structural strength is high.

[0073] In some embodiments of the air duct assembly of the present utility model, as Figure 2-5 As shown, the bearing 120 is circumferentially provided with an annular positioning groove 121 .

[0074] The limiting structure 142 includes a positioning rib 210, which protrudes from the hole wall of the installation through hole 141 and is integrally formed with the installation through hole 141. The positioning rib 210 includes a stopper 211 and a supporting chamfer 212, wherein the upper end of the stopper 211 stops the top surface of the positioning groove, and the supporting chamfer 212 is fixedly connected to the lower side of the stopper 211.

[0075] In this embodiment, the limiting structure 142 and the bearing 120 are limited by ribs and groove structures. Specifically, an annular positioning groove 121 is provided on the peripheral wall of the bearing 120, and a protruding stopper 211 and a supporting chamfer 212 are integrally formed on the hole wall of the mounting through hole 141. When the bearing 120 is inserted into the mounting through hole 141 axially from bottom to top, the top surface of the annular positioning groove 121 is deformed and contracted under the extrusion of the full angle of the support, and is restored when passing through the stopper 211. At this time, the top surface of the annular positioning groove 121 contacts the upper surface of the stopper 211, and the stopper 211 stops the bearing 120 from moving downward, that is, stops the bearing 120 from downwardly disengaging from the mounting through hole 141.

[0076] Compared with providing a groove on the hole wall of the installation through hole 141, the positioning rib 210 in this embodiment protrudes outward from the hole wall of the installation through hole 141. During casting, the upper and lower molds can be easily demolded, thereby reducing the manufacturing cost.

[0077] In some embodiments of the air duct assembly of the present utility model, as Figure 2-5 As shown, the limiting structure 142 also includes a stop rib 220, which protrudes from the hole wall of the installation through hole 141, is integrally formed with the installation through hole 141, and is located on the upper side of the positioning rib 210 in the vertical direction. The height of the stop rib 220 extending from the hole wall of the installation through hole 141 is greater than the height of the positioning rib 210 extending from the hole wall of the installation through hole 141.

[0078] In this embodiment, the stopping rib 220 is located on the upper side of the positioning rib 210 and is used to stop the upper end of the bearing 120 to prevent the bearing 120 from passing through the mounting through hole 141 upward.

[0079] Furthermore, the height of the stopping rib 220 extending from the hole wall of the mounting hole 141 is greater than the height of the positioning rib 210 extending from the hole wall of the mounting hole 141, which can prevent the bearing 120 from deforming under strong force and passing upward through the mounting hole 141.

[0080] In some embodiments of the air duct assembly of the present utility model, as Figure 2-3 As shown, the installation through hole 141 is a circular hole. There are a plurality of positioning ribs 210 , which are arranged at intervals along the circumference of the installation through hole 141 .

[0081] On the one hand, the plurality of positioning ribs 210 can limit the bearing 120 from multiple directions to prevent the bearing 120 from tilting. On the other hand, it is convenient to demould during casting.

[0082] In some embodiments of the air duct assembly of the present utility model, as Figure 2-5 As shown, the limiting structure 142 also includes a stop rib 220, which protrudes from the hole wall of the installation through hole 141, is integrally formed with the installation through hole 141, and is located on the upper side of the positioning rib 210 in the vertical direction. There are multiple stop ribs 220, which are arranged at intervals along the circumference of the installation through hole 141.

[0083] On a horizontal projection plane, the positioning ribs 210 and the stopping ribs 220 are arranged at intervals along the circumference of the mounting through hole 141 .

[0084] On the one hand, the plurality of stop ribs 220 can limit the bearing 120 from multiple directions to prevent the bearing 120 from passing upwardly out of the mounting through hole 141. On the other hand, it is convenient to demould during casting.

[0085] In particular, the positioning rib 210 and the stopping rib 220 are arranged at intervals along the circumference of the mounting hole 141 on the horizontal projection plane. During casting, there is no need to additionally set up a tilting device, and the upper and lower molds can be demolded at one time, thereby improving production efficiency and reducing manufacturing costs.

[0086] In some embodiments of the air duct assembly of the present utility model, as Figure 2-3 As shown, the air duct assembly 100 further includes a top plate 150, and the end plate 130 is integrally formed on the top plate 150. The top surface of the top plate 150 is lower than the top surface of the end plate 130. A drainage hole 160 is provided on the top surface of the top plate 150.

[0087] The edges around the top surface of the end plate 130 are raised upward to form a water retaining rib 170 , and at least one drainage notch 180 is provided near the drainage hole 160 of the water retaining rib 170 .

[0088] The top of the water retaining rib 170 is lower than the top of the mounting through hole 141 .

[0089] In this embodiment, the end plate 130 may be circular, and the water retaining rib 170 may be annular. By providing the drainage notch 180 and the drainage hole 160, condensed water can be discharged in time to prevent condensed water from accumulating on the top plate 150 or the end plate 130 and entering the mounting through hole 141, thereby affecting the service life of the bearing 120.

[0090] On the other hand, since the top of the water retaining rib 170 is lower than the top of the installation through hole 141 , even if condensed water is retained in the water retaining rib 170 , it will not flow into the installation through hole 141 .

[0091] In some embodiments of the air duct assembly of the present utility model, as Figure 2-3 As shown, a plurality of reinforcing ribs are radially arranged between the outer peripheral wall of the bearing mounting seat 140 and the water retaining rib 170 to improve the structural strength of the bearing mounting seat 140 and the end plate 130 and provide a firm support for the wind wheel 110 .

[0092] In some embodiments of the air duct assembly of the present invention, the top surface of the top plate 150 is flush with the top surface of the end plate 130 .

[0093] In some embodiments of the air conditioning cabinet of the present utility model, the air conditioning cabinet includes the above-mentioned air duct assembly 100, and one or more air ducts 300 are formed in the air duct assembly 100. Each air duct 300 is provided with a wind wheel 110, and the wind wheel 110 is configured to blow the temperature-controlled airflow out of the air duct 300 from the air outlet.

[0094] In some embodiments of the air conditioner cabinet of the utility model, the wind wheel 110 is a crossflow wind wheel. The crossflow wind wheel has a large air volume and uniform air discharge, but is usually long. Therefore, the installation accuracy of the rotating shafts at both ends of the crossflow wind wheel directly affects the operating stability and air discharge effect of the crossflow wind wheel. The air conditioner cabinet of this embodiment can achieve high-precision assembly by integrally forming the bearing mounting seat 140 on the end plate 130 at the upper end of the air duct 300, better exerting the advantages of the crossflow wind wheel and optimizing the air discharge effect.

[0095] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
