Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an air duct assembly and an air conditioner. Background Technology

[0002] Air conditioning ducts generally include at least a duct plate and a volute. The volute, as an important component of the duct, usually has a complex profile design. Therefore, the volute is usually machined as a separate part and then assembled onto the duct plate. However, in the current assembly process of air conditioning ducts, the assembly of the volute is quite difficult.

[0003] In summary, overcoming the aforementioned defects of existing air conditioning ducts is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a duct assembly and an air conditioner to alleviate the technical problem of high difficulty in assembling the volute in existing air conditioning ducts.

[0005] The air duct assembly provided by the present invention includes an air duct plate and a volute.

[0006] The air duct plate is provided with an installation part, which has a clearance groove and a first snap-fit ​​part. The two opposite groove walls of the clearance groove are the first groove wall and the second groove wall, respectively.

[0007] The volute tongue is provided with a barb and a second locking part. The side of the barb facing away from the air duct plate contacts and engages with the first groove wall. There is a gap between the second groove wall and the barb. The second locking part engages with the first locking part.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] The air duct assembly provided by this invention has a pre-reserved gap between the second groove wall of the clearance groove and the barb, which can meet the requirement that the barb is inserted into the clearance groove at a certain angle (relative to the assembly position) and rotates within the clearance groove. Therefore, when assembling the air duct assembly, the volute tongue can be moved to a position close to the mounting part at a certain angle, and the barb on the volute tongue can be inserted into the clearance groove on the air duct plate at a certain angle, and the barb hooks onto the first groove wall of the clearance groove. At this time, the side of the barb facing away from the air duct plate will abut against the first groove wall. The abutment point between the first groove wall and the barb can serve as the rotation fulcrum of the volute tongue. Then, the volute tongue is rotated around the rotation fulcrum, so that the second locking part on the volute tongue gradually approaches the first locking part on the air duct plate until the first locking part and the second locking part lock together. In this way, the assembly of the volute tongue and the air duct plate can be realized.

[0010] Therefore, the air duct assembly provided by the present invention can not only increase the success rate of one-time assembly and greatly shorten the time spent adjusting the position of the volute tongue during assembly, but also reduce the manpower required for assembly, making installation easier, saving time and effort, and increasing assembly efficiency.

[0011] Preferably, as one possible implementation, the volute tongue has a first sidewall and a second sidewall disposed opposite to each other, the barb is disposed on the first sidewall, and the second snap-fit ​​portion is disposed on the second sidewall.

[0012] The opening of the clearance groove faces away from the first snap-fit ​​part.

[0013] The beneficial effect is that it facilitates a stronger connection between the volute tongue and the mounting part, thus making the volute tongue less prone to loosening.

[0014] Preferably, as one possible implementation, the second wall of the clearance groove overlaps with the air duct plate.

[0015] The barb is spaced from the end of the first sidewall near the air duct plate; and / or the opening width between the air duct plate and the volute tongue is in the range of 4 to 5 mm.

[0016] The beneficial effects include alleviating surge problems, reducing noise, improving product quality, and thus enhancing the user experience.

[0017] Preferably, as one possible implementation, there are multiple barbs, and the multiple barbs are arranged at intervals along the length direction of the worm tongue.

[0018] The beneficial effect is that it can improve the uniformity of force distribution on the cochlear tongue and enhance structural stability.

[0019] Preferably, as one possible implementation, there are multiple second locking parts, and the multiple second locking parts are respectively distributed at the top and middle of the volute tongue;

[0020] And / or, there are multiple second locking parts, and the multiple locking parts are respectively distributed at the top and middle of the volute tongue.

[0021] The beneficial effect is that it can improve the uniformity of force distribution on the cochlear tongue and enhance structural stability.

[0022] Preferably, as one possible implementation, the first snap-fit ​​part is a buckle, and the second snap-fit ​​part is a snap hole formed on the volute tongue, wherein the buckle engages with the snap hole.

[0023] The beneficial effect is that it enables card-to-card connections.

[0024] Preferably, as one possible implementation, the volute tongue is a groove structure with its opening facing the air duct plate.

[0025] The beneficial effects are that it not only improves the connection stability between the volute tongue and the air duct plate, but also reduces material usage and lowers costs.

[0026] Preferably, as one possible implementation, the part of the volute tongue that mates with the mounting part is an assembly part, the suspended part of the volute tongue is a cantilever part, and the ratio of the assembly part to the suspended part of the volute tongue in the groove depth direction is in the range of 1:3.5 to 1:2.5.

[0027] The beneficial effect is that it allows the worm tongue to complete the rotation assembly smoothly, and the worm tongue is not easy to loosen after the assembly is completed.

[0028] Preferably, as one possible implementation, the groove of the volute tongue is provided with a plurality of ribs, the ribs including a plurality of high ribs and a plurality of low ribs, the area of ​​the high ribs being larger than the area of ​​the low ribs, and the high ribs and the low ribs being arranged intersectingly along the length direction of the volute tongue.

[0029] The beneficial effects are that it can ensure a better strengthening effect while reducing costs. In addition, the uniformity of structural strength of various parts of the cochlear tongue is better, which can reduce the risk of local deformation due to poor local strength.

[0030] Preferably, as one possible implementation, the three sides of the stiffener are respectively connected to the three walls of the noise reduction cavity.

[0048] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0050] See Figures 1-4This embodiment provides an air duct assembly, which includes an air duct plate 100 and a volute tongue 300. The air duct plate 100 is provided with a mounting part 200, which has a clearance groove 210 and a first snap-fit ​​part. The two opposite groove walls of the clearance groove 210 are a first groove wall 211 and a second groove wall 212, respectively. The volute tongue 300 is provided with a barb 311 and a second snap-fit ​​part. The side of the barb 311 facing away from the air duct plate 100 contacts and engages with the first groove wall 211. There is a gap between the second groove wall 212 and the barb 311. The second snap-fit ​​part engages with the first snap-fit ​​part.

[0051] The air duct assembly provided in this embodiment has a pre-reserved gap between the second groove wall 212 of the clearance groove 210 and the barb 311, which can meet the requirement that the barb 311 is inserted into the clearance groove 210 at a certain angle (relative to the assembly orientation) and rotates within the clearance groove 210. Therefore, when assembling the air duct assembly, the volute tongue 300 can be moved at a certain angle to a position close to the mounting part 200, and the barb 311 on the volute tongue 300 can be inserted into the clearance groove 210 on the air duct plate 100 at a certain angle, and the barb 311 can be rotated within the clearance groove 210. 11 hooks onto the first groove wall 211 of the clearance groove 210. At this time, the side of the barb 311 facing away from the air duct plate 100 will abut against the first groove wall 211. The abutment point between the first groove wall 211 and the barb 311 can serve as the rotation fulcrum of the volute tongue 300. Then, the volute tongue 300 is rotated around the rotation fulcrum, so that the second locking part on the volute tongue 300 gradually approaches the first locking part on the air duct plate 100 until the first locking part and the second locking part are locked together. In this way, the assembly of the volute tongue 300 and the air duct plate 100 can be realized.

[0052] Therefore, the air duct assembly provided in this embodiment can not only increase the probability of successful assembly on the first attempt and greatly shorten the time spent adjusting the position of the volute tongue 300 during assembly, but also reduce the manpower required for assembly, making installation easier, saving time and effort, and increasing assembly efficiency.

[0053] See Figure 3 The two opposite sidewalls of the volute tongue 300 are defined as the first sidewall 310 and the second sidewall 320, respectively. The barb 311 is provided on the first sidewall 310, and the second snap-fit ​​part is provided on the second sidewall 320. At the same time, the opening of the clearance groove 210 is set opposite to the first snap-fit ​​part. In this way, the opposite sides of the volute tongue 300 can be connected to the opposite sides of the mounting part 200, which can improve the connection between the volute tongue 300 and the mounting part 200. As a result, the volute tongue 300 is not easy to loosen and has strong firmness.

[0054] Specifically, the second groove wall 212 of the aforementioned clearance groove 210 coincides with the air duct plate 100, that is, the clearance groove 210 is equivalent to being formed by the mounting part 200 and the air duct plate 100 together.

[0055] Preferably, see Figure 2 and Figure 4 This arrangement creates a gap between the barb 311 and the end of the first sidewall 310 closest to the air duct plate 100. That is, the position of the barb 311 on the first sidewall 310 is not the edge of the first sidewall 310. In this way, while ensuring the fit requirements between the barb 311 and the clearance groove 210, the opening between the volute tongue 300 and the air duct plate 100 can be reduced by lengthening the first sidewall 310 in the direction toward the air duct plate 100. This can alleviate the surge problem, reduce noise, improve product quality, and thus improve the user experience.

[0056] Specifically, the opening width between the air duct plate 100 and the volute tongue 300 can be set to 4-5 mm. Within this range, turbulence problems can be better suppressed.

[0057] Preferably, see Figure 3 By setting multiple barbs 311 and arranging them at intervals along the length of the volute tongue 300, the uniformity of force distribution on the volute tongue 300 can be improved, and the structural stability can be strengthened.

[0058] Multiple second snap-fit ​​parts can be configured and distributed at the top and middle of the volute tongue 300, thereby further improving the uniformity of force distribution on the volute tongue 300 and enhancing its structural stability.

[0059] Specifically, the first snap-fit ​​part can be set as a snap fastener 220, and the corresponding second snap-fit ​​part can be set as a snap hole 321 opened on the volute tongue 300. The snap fastener 220 and the snap hole 321 cooperate with each other to achieve snap-fit.

[0060] Preferably, see Figure 3 and Figure 4 The volute tongue 300 is configured as a groove structure with the slot facing the air duct plate 100. This can greatly reduce the weight of the volute tongue 300, not only improving the connection stability between the volute tongue 300 and the air duct plate 100, but also reducing the amount of material used and lowering the cost.

[0061] See Figure 2 The part of the volute tongue 300 that mates with the mounting part 200 is defined as the assembly part, and the suspended part of the volute tongue 300 (i.e., the part other than the assembly part) is defined as the cantilever part. The ratio A:B of the assembly part and the cantilever part of the volute tongue 300 in the groove depth direction of the volute tongue 300 is set to a range of 1:3.5 to 1:2.5. In this way, the volute tongue 300 can be smoothly rotated and assembled, and after the assembly is completed, the volute tongue 300 is not easy to loosen, which can ensure product quality and production efficiency and improve user experience.

[0062] Preferably, the ratio A:B of the mounting portion and the cantilever portion of the volute tongue 300 in the groove depth direction of the volute tongue 300 is set to 1:3.

[0063] Preferably, see Figure 3 and Figure 4 Multiple stiffeners are provided in the groove of the volute tongue 300. The stiffeners can improve the structural strength of the volute tongue 300 and prevent the volute tongue 300 from deforming.

[0064] Multiple stiffeners are divided into high stiffeners 330 and low stiffeners 340. The area of ​​the high stiffeners 330 is set to be larger than that of the low stiffeners 340. The presence of the high stiffeners 330 can ensure a better strengthening effect, while the setting of the low stiffeners 340 can reduce material usage and lower costs. The high stiffeners 330 and low stiffeners 340 are arranged in a cross pattern along the length of the volute tongue 300, which can improve the uniformity of structural strength of various parts of the volute tongue 300 and reduce the risk of local deformation due to poor local strength.

[0065] Specifically, connecting the three sides of the stiffening plate to the bottom and wall of the groove of the volute tongue 300 respectively can improve the strengthening effect of the stiffening plate on the volute tongue 300.

[0066] Preferably, the shape of the low rib 340 is set to a "U" shape, and the notch of the low rib 340 is set to face the groove side of the volute tongue 300. In this way, the strengthening effect of the low rib 340 on the volute tongue 300 can be improved without changing the area of ​​the low rib 340.

[0067] Furthermore, by setting the stiffener plate perpendicular to the length direction of the volute tongue 300, the reinforcing effect of the stiffener plate can be improved.

[0068] This embodiment also provides an air conditioner that includes the above-described air duct assembly.

[0069] The air conditioner provided in this embodiment, having the aforementioned air duct assembly, possesses all the advantages of such duct assemblies. It has a higher probability of successful assembly on the first attempt, requires less manpower to assemble with the volute 300, is easier to install, saves time and effort, and has high assembly efficiency. Assembly is time-saving, labor-saving, and highly efficient.

[0070] In summary, the embodiments of this invention disclose a duct assembly and an air conditioner that overcome many technical defects of traditional air conditioning ducts. The duct assembly and air conditioner provided by these embodiments have a high probability of successful assembly on the first attempt. The volute 300 requires less manpower to assemble, making installation easier, time-saving, and labor-saving, resulting in higher assembly efficiency.
