For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] First, the air duct assembly of the existing vertical air conditioner is described. The air duct assembly of the vertical air conditioner includes a vertically arranged volute and a volute tongue. The volute and the volute tongue are arranged opposite to each other and connected to each other. The volute tongue and the volute jointly limit the outlet air duct. One vertical side of the heat exchanger is sealed to the side of the volute away from the air outlet. The other vertical side of the heat exchanger is sealed to the side of the volute tongue through a sealing plate. The sealing plate is used to guide the air passing through the heat exchanger and flowing to the sealing plate to the air inlet of the outlet air duct. In order to facilitate disassembly, the existing volute and volute tongue are usually connected by a snap-on method, but the snap-on structure cannot guarantee the stability of the connection between the volute and the volute tongue, which may cause the volute and the volute tongue to produce abnormal noise or even separate during operation, affecting the normal use of the vertical air conditioner. For this reason, the following implementation method is proposed.

[0028] like Figure 1-Figure 4 As shown, in order to solve the problem of poor structural stability of the air duct assembly 1 of the existing vertical air conditioner, the air duct assembly 1 of the vertical air conditioner of the utility model includes a volute 11 and a volute tongue 12, the internal space of the volute 11 encloses an air duct 13, a top plate 17 is provided on the top of the volute 11, and a bottom plate 18 is provided on the bottom, the volute tongue 12 is arranged in the air duct 13 and is integrally formed with the volute 11.

[0029] In the case of adopting the above-mentioned embodiment, during the installation process of the air duct assembly 1 of the vertical air conditioner of the utility model, it is only necessary to install the top plate 17 and the bottom plate 18 on the upper and lower ends of the volute 11 by means of clamping or screw fixing, and it is not necessary to clamp the volute tongue 12 on the volute 11 as in the prior art, thereby simplifying the installation process of the air duct assembly 1. At the same time, since the volute 11 and the volute tongue 12 are integrally formed, the connection strength between the volute 11 and the volute tongue 12 is higher, and the structural stability is stronger, thereby solving the problem of poor structural stability of the air duct assembly 1 of the vertical air conditioner in the prior art. In addition, a circular air inlet is provided on the top plate 17, and the vertical air conditioner also includes a fan, and the air outlet 14 of the fan is connected to the air inlet on the top plate 17, so that the wind blown by the fan can enter the air duct 13 surrounded by the volute 11 through the air inlet.

[0030] The main embodiments of the present invention have been introduced above, and some preferred embodiments of the present invention are introduced next. Other embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-Figure 4As shown, in a possible embodiment, a closed space is not formed inside the volute 11, and an air outlet 14 is provided on one side of the volute 11. It can be seen from the connection between the bottom plate 18 and the volute 11 in the figure that the width of the air outlet 14 gradually increases from the inside to the outside, and is in the form of a trumpet-shaped outward expansion. A volute support 15 is provided at the air outlet 14, and both ends of the volute support 15 are respectively connected to the side walls of the volute 11.

[0032] The advantages of the above arrangement are: as mentioned above, a circular air inlet is provided on the top plate 17 to transport air into the air duct 13. Similarly, in order to achieve the conduction of air by the air duct 13, an air outlet 14 is still necessary on the volute 11. Since the width of the air outlet 14 gradually increases from the inside to the outside, when the air is blown out from the air outlet 14, the larger opening width can increase the area of ​​the air flow. In addition, in order to improve the structural stability of the air duct assembly 1, a volute support 15 is also provided at the air outlet 14 in this embodiment. The volute support 15 is connected to both sides of the volute 11 to ensure the structural strength of the volute 11 at the air outlet 14.

[0033] Furthermore, in a possible implementation, the volute support 15 and the volute 11 are integrally formed.

[0034] The advantage of the above embodiment is that the structural strength of the volute 11 is further enhanced by arranging the volute support 15 and the volute 11 to be integrally formed, thereby ensuring the stability of the internal structure of the air duct 13.

[0035] In a possible implementation, Figure 1-Figure 4 As shown, the air duct assembly 1 also includes a swing blade module 16, which includes a swing blade connecting rod 161, a swing blade 162 and a driving device 163. The first end of the swing blade 162 is pivotally set on the volute tongue 12, and the second end of the swing blade 162 is connected to the swing blade connecting rod 161. The swing blade connecting rod 161 is provided with a vertical waist hole 1611. The second end of the swing blade 162 is slidably set in the waist hole 1611. The swing blade connecting rod 161 is connected to the driving device 163. The swing blade connecting rod 161 can drive the swing blade 162 to swing on the volute tongue 12 under the drive of the driving device 163. The driving device 163 is installed on the top plate 17, and the top plate 17 is also provided with a clearance groove 171 for passing the swing blade connecting rod 161.

[0036] It is mentioned above that the air circulation in the air duct 13 is achieved by setting an air inlet on the top plate 17 and an air outlet 14 on the volute 11. In order to further enhance the air circulation effect, a swing blade module 16 is set in the air duct 13 in this embodiment. In the process of the air duct assembly 1 of the utility model, the driving device 163 drives the output shaft to make a circular motion in the vertical plane, and the output shaft drives the swing blade connecting rod 161 to swing up and down in the vertical direction after passing through the air avoidance groove 171. At this time, the second end of the swing blade 162 moves up and down in the waist hole 1611 of the swing blade connecting rod 161. Sliding, when the second end of the pendulum blade 162 contacts the upper boundary of the waist hole 1611, since the first end of the pendulum blade 162 is pivotally set on the volute tongue 12, the second end of the pendulum blade 162 will tilt downward under the drive of the pendulum blade connecting rod 161, and the first end of the pendulum blade 162 will tilt upward. Similarly, when the first end of the pendulum blade 162 contacts the lower boundary of the waist hole 1611, the second end of the pendulum blade 162 will tilt upward under the drive of the pendulum blade connecting rod 161, and the first end of the pendulum blade 162 will tilt downward, thereby achieving the effect of accelerating the air circulation inside the air duct 13 through the pendulum blade 162.

[0037] like Figure 1-Figure 4 As shown, in a possible embodiment, a reinforcing rib 1621 is provided at the first end of the pendulum blade 162. The reinforcing rib 1621 is conical, and the thickness of the reinforcing rib 1621 gradually decreases from a position close to the first end of the pendulum blade 162 to a position far from the first end of the pendulum blade 162.

[0038] The advantages of the above-mentioned embodiment are: as mentioned above, the swinging of the pendulum blade 162 is achieved by the pivoting of the pendulum blade 162 on the volute tongue 12 under the drive of the pendulum blade connecting rod 161, that is, the force-bearing part during the swinging process of the pendulum blade 162 is the position of the first end and the second end of the pendulum blade 162. Based on this, in the present embodiment, a conical reinforcement rib 1621 is provided at the first end of the pendulum blade 162, and the reinforcement rib 1621 is arranged from a position close to the first end of the pendulum blade 162 to a position far away from the first end of the pendulum blade 162, and the thickness of the reinforcement rib 1621 gradually decreases, so that the thickness of the reinforcement rib 1621 is thicker at the position where the force on the pendulum blade 162 is greater, thereby enhancing the structural strength of the pendulum blade 162 and improving the stability of the pendulum blade module 16.

[0039] In addition, regarding the shape of the above-mentioned reinforcing rib 1621, the above description is only one of many implementations, and is not a limitation on the shape of the reinforcing rib 1621 in the present invention. Those skilled in the art can also set the reinforcing rib 1621 to other common shapes, such as square or wedge-shaped, etc., as long as it can play the role of strengthening the structural strength of the swing blade 162. These changes do not exceed the technical principles of the present invention, and therefore will be included in the protection scope of the present invention.

[0040] like Figure 3 , Figure 4 As shown, in a possible implementation manner, a guide pattern 1622 is provided on the blade surface of the swing blade 162, and the shape of the guide pattern 1622 is set to be a hexagonal shape.

[0041] In the case of adopting the above-mentioned embodiment, by setting the guide pattern 1622 on the blade surface of the swing blade 162, the guide pattern 1622 can increase the contact area between the blade surface of the swing blade 162 and the air during the swing of the swing blade 162 on the air in the air duct 13, thereby enhancing the swing effect of the swing blade 162 on the air flow in the air duct 13. In addition, it can be understood by those skilled in the art that the above-mentioned guide pattern 1622 can be a guide protrusion protruding outward or a guide groove concave inward, as long as it can increase the contact area between the swing blade 162 and the air flow in the air duct 13. In addition, although it is mentioned above that the guide pattern 1622 can be set to a hexagonal shape, this is not a limitation on the shape of the guide pattern 1622 in the utility model. Those skilled in the art can also set the guide pattern 1622 to other common shapes, such as triangle, square, rectangle or circle, etc. These changes do not exceed the technical principle of the utility model, and therefore will also be included in the protection scope of the utility model.

[0042] It is mentioned above that the air outlet 14 of the volute 11 is set to be similar to a trumpet-shaped outward expansion form. However, in the actual use of the vertical air conditioner, if the width of the air outlet 14 is not set reasonably, a "wheezing phenomenon" will appear at the air outlet 14 of the air duct 13. "Wheezing phenomenon" in the air conditioning system usually refers to a continuous noise or sound, similar to the wheezing sound when breathing. In the air conditioning system, when the air flow is not smooth or there are obstacles, noise similar to wheezing sound may also be caused, especially in the air duct 13 or the air circulation path. For this reason, the present embodiment is proposed. In a possible embodiment, the minimum width of the air outlet 14 is less than 60mm.

[0043] When the length of the evaporator is 405 mm and the minimum width of the air outlet 14 is 71.1 mm, the area of ​​the air outlet 14 accounts for 17.7% of the area of ​​the evaporator, and when the minimum width of the air outlet 14 is 60 mm, the area of ​​the air outlet 14 accounts for 14.8 of the area of ​​the evaporator. Through experimental verification, it is found that when the ratio of the area of ​​the air outlet 14 to the area of ​​the evaporator is less than 15%, the air conditioner will not produce a wheezing phenomenon. Therefore, in this embodiment, the minimum width of the air outlet 14 is set to less than 60 mm, thereby avoiding the wheezing phenomenon at the air outlet 14 and improving the user experience.

[0044] It should be noted that the above-mentioned implementation mode is only used to illustrate the principle of the utility model, and is not intended to limit the protection scope of the utility model. Without departing from the principle of the utility model, those skilled in the art can adjust the above-mentioned structure so that the utility model can be applied to more specific application scenarios.

[0045] In addition, the utility model also provides a vertical air conditioner, which includes the air duct assembly 1 of the vertical air conditioner mentioned in any of the above embodiments.

[0046] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
