The air duct includes an arc section that first bends upward and then bends downward in the direction from the first port to the second port.

[0007] According to the air duct of the embodiment of the utility model, since the arc section first bends upward and then bends downward in the direction from the first port to the second port, the second port can be made to open downward, so as to reduce the probability of external dust entering the air duct from the second port, making the inner wall of the air duct not easily dirty and being conducive to improving the cleanliness of the air duct.

[0008] In some embodiments, the arc section is arc-shaped and transitional at the bending position from top to bottom.

[0026] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0027] Below, refer to the attached Figures 1 to 4 Describe the air duct and the vertical air conditioner of the embodiments of the present utility model.

[0028] As Figures 1 to 4 shown, the air duct 3 of the embodiments of the present utility model has a first port 311 and a second port 321. The first port 311 is used to communicate with the air outlet end of an air outlet module (not shown), and the second port 321 is used to communicate with the air outlet 11 of the vertical air conditioner. The air duct 3 includes an arc section 32. The arc section 32 first bends and extends upward and then bends and extends downward in the direction from the first port 311 to the second port 321.

[0029] According to the air duct 3 of the embodiments of the present utility model, since the arc section 32 first bends and extends upward and then bends and extends downward in the direction from the first port 311 to the second port 321, the second port 321 can be made to open downward, so as to reduce the probability that external dust enters the air duct 3 through the second port 321, making the inner wall of the air duct 3 not easily soiled, which is beneficial to improving the cleanliness of the air duct 3.

[0030] On the other hand, since the arc section 32 first bends and extends upward and then bends and extends downward in the direction from the first port 311 to the second port 321, the structure of the air duct 3 can be made compact, which is beneficial to the layout and assembly of the air duct 3 in the vertical air conditioner.

[0031] It should be noted that the second port 321 of the air duct 3 can be directly communicated with the air outlet 11 of the vertical air conditioner, or can be communicated with the air outlet 11 of the vertical air conditioner through the air outlet housing 2. This application does not make any limitation thereto.

[0032] Optionally, as Figures 2 to 4As shown, the arc segment 32 is arc-shaped and transitions at the bending position from top to bottom. It can be understood that the bending position where the arc segment 32 bulges upward has a certain curvature, which can reduce the wind resistance of the air flow passing through the bending position of the arc segment 32 and reduce the energy consumption of the floor-standing air conditioner.

[0033] Specifically, as Figures 2 to 4 shown, the air duct 3 further includes a straight segment 31 communicating with the arc segment 32. One end of the straight segment 31 adjacent to the air outlet module forms a first port 311, and the other end of the straight segment 31 is arc-shaped and connected to the arc segment 32. It can be understood that the inner diameter of the straight segment 31 is constant and extends in a single direction. For example, the straight segment 31 can extend horizontally. By designing one end of the air duct 3 adjacent to the first port 311 as the straight segment 31 in the embodiment of the present utility model, it is convenient for the assembly work of the air duct 3 and the air outlet module, and is beneficial to improving the sealing effect of the connection position between the air duct 3 and the air outlet module.

[0034] In some embodiments, as Figures 2 to 4 shown, the arc segment 32 has an upper arc surface 34 and a lower arc surface 33. The upper arc surface 34 bulges upward, and the lower arc surface 33 is recessed into the interior of the air duct 3. In other words, the center of the curvature circle of the upper arc surface 34 is located below the upper arc surface 34, and the center of the curvature circle of the lower arc surface 33 is located below the lower arc surface 33. This can further improve the smoothness of the air flow in the air duct 3, further reduce the wind resistance, and reduce the energy consumption of the floor-standing air conditioner.

[0035] Furthermore, as Figure 3 shown, in the direction from the first port 311 to the second port 321 of the air duct 3, the distance between the upper arc surface 34 and the lower arc surface 33 gradually decreases, which can increase the wind speed when the air flow is discharged from the second port 321 and improve the air guiding effect of the air duct 3.

[0036] For another example, as Figure 3 shown, in the direction from the first port 311 to the second port 321 of the air duct 3, the curvature of the upper arc surface 34 and the lower arc surface 33 gradually increases. The inventor of the present application found through experimental research that when the curvature of the upper arc surface 34 and the lower arc surface 33 is arranged in the above structure, the smoothness of the air flow in the air duct 3 can be improved, the wind resistance can be further reduced, and the energy consumption of the floor-standing air conditioner can be reduced.

[0037] In some embodiments, as Figure 3As shown, the second port 321 opens downwardly and obliquely, and the upper edge of the second port 321 is closer to the front end of the air duct 3 than the lower edge of the second port 321. The upper edge of the second port 321 is the edge on the upper side of the second port 321. The lower edge of the second port 321 is the edge on the lower side of the second port 321. By arranging the second port 321 in the above structure for the air duct 3 of the embodiment of the present utility model, the air flow discharged from the second port 321 can be discharged downwardly and forwardly, so as to improve the air guiding effect of the air duct 3.

[0038] And because the second port 321 has a certain inclination angle, when the air outlet housing 2 is assembled with the air duct 3, under the guiding action of the inclined surface of the second port 321, the air outlet housing 2 can be smoothly inserted into the housing 1 in the front-to-rear direction and be opposite to the first port 311, thereby improving the convenience of assembling the components of the floor-standing air conditioner and being beneficial to improving the production efficiency.

[0039] In addition, since the second port 321 opens downwardly and forwardly, it is possible to avoid a large curvature of the arc section 32 of the air duct 3, so that the air duct 3 can be smoothly demolded during production, improving the convenience of processing and manufacturing the air duct 3.

[0040] Optionally, as Figure 2 and Figure 4 shown, the air duct 3 includes a first half shell 35 and a second half shell 36 which are connected to each other. The first half shell 35 and the second half shell 36 are arranged in the up-and-down direction to enclose the air duct 3. It can be understood that the first half shell 35 and the second half shell 36 can be separately manufactured and then assembled together to form the air duct 3. This can facilitate the processing and manufacturing of the air duct 3 and is convenient for demolding.

[0041] For example, the first half shell 35 and the second half shell 36 are detachably connected.

[0042] Optionally, as Figure 4 shown, one of the first half shell 35 and the second half shell 36 is provided with a convex stop 351, and the other is provided with a concave stop 361. The convex stop 351 and the concave stop 361 are in snap-fit. For example, the first half shell 35 is provided with a convex stop 351, and the second half shell 36 is provided with a concave stop 361, and the convex stop 351 and the concave stop 361 are engaged.

[0043] It can be understood that the concave stop 361 is arranged along the extending direction of the first half shell 35, and the concave stop 361 is provided on both sides in the width direction of the first half shell 35. The convex stop 351 is arranged along the extending direction of the second half shell 36, and the convex stop 351 is provided on both sides in the width direction of the second half shell 36. The concave stop 361 and the convex stop 351 cooperate with each other, which can improve the sealing effect between the first half shell 35 and the second half shell 36 and avoid the problem of air leakage at the splicing position between the first half shell 35 and the second half shell 36.

[0044] As shown Figure 4 in FIG. 1, a first ear seat 352 is provided on the first half shell 35, a second ear seat 362 is provided on the second half shell 36, and the air duct 3 further includes a threaded member which passes through the first ear seat 352 and the second ear seat 362. It can be understood that the first half shell 35 and the second half shell 36 are connected by means of fastening with the threaded member, so as to facilitate the installation and disassembly of the air duct 3. For example, there are two first ear seats 352, and the two first ear seats 352 are arranged at intervals along the extending direction of the first half shell 35. There are two second ear seats 362 which correspond to the two first ear seats 352 one by one, thereby improving the firmness of the connection between the first half shell 35 and the second half shell 36.

[0045] As shown Figure 1 in FIGS. 2 Figure 4 and 3, a vertical air conditioner according to another embodiment of the present invention includes an air duct 3, a housing 1 and an air outlet module. The air duct 3 is the air duct 3 of the present invention. Both the air duct 3 and the air outlet module are arranged in the housing 1. An air outlet 11 is provided on the housing 1. A first port 311 of the air duct 3 is communicated with the air outlet module, and a second port 321 of the air duct 3 is communicated with the air outlet 11.

[0046] In the vertical air conditioner according to the embodiment of the present invention, since the arc section 32 first bends and extends upward and then bends and extends downward in the direction from the first port 311 to the second port 321, the second port 321 can be made to open downward, so as to reduce the probability that external dust enters the air duct 3 from the second port 321, making the inner wall of the air duct 3 not easily soiled, which is beneficial to improving the cleanliness of the air duct 3.

[0047] Optionally, as shown Figure 4 in FIG. 4, the vertical air conditioner further includes an air outlet housing 2. An air outlet channel 23 communicated with the air outlet 11 is provided in the air outlet housing 2. A downward air guiding port 211 is provided on the upper end surface of the air outlet housing 2. The second port 321 is communicated with the air outlet 11 through the air guiding port 211. Since the downward air guiding port 211 is provided on the upper end surface of the air outlet housing 2, external floating dust will fall into the air outlet channel 23 and is not easily upwardly introduced into the air guiding port 211, and external floating dust is also not easily introduced into the air duct 3 through the air guiding port 211.

[0048] Optionally, as shown Figure 4As shown, the top of the air outlet housing 2 is provided with a first flange 212 and a second flange 213, the lower edges of the first flange 212 and the second port 321 abut against each other, and the second flange 213 and the upper edges of the second port 321 abut against each other. When the air outlet housing 2 is assembled with the air duct 3, under the guiding effect of the inclined surface of the second port 321, the air outlet housing 2 can be smoothly inserted into the housing 1 from the front to the back and the second flange 213 and the first flange 212 are respectively opposite to the upper and lower edges of the first port 311, thereby improving the convenience of assembling the parts of the vertical air conditioner and facilitating improving the production efficiency.

[0049] It can be understood that the second port 321 opens obliquely in the forward and downward direction, and the upper edge of the second port 321 is closer to the front end of the air duct 3 than the lower edge of the second port 321. Correspondingly, the second flange 213 is arranged at the front end of the first flange 212 and is higher than the first flange 212. In this way, the lower edge of the second port 321 can match the first flange 212, and the upper edge of the second port 321 can match the second flange 213.

[0050] For example, the joint position of the first flange 212 and the lower edge of the second port 321 has a sealing foam. The joint position of the second flange 213 and the upper edge of the second port 321 has a sealing foam. In this way, the problem of air leakage at the joint position of the air outlet housing 2 and the air duct 3 can be prevented, and the sealing effect of the connection between the air outlet housing 2 and the air duct 3 can be improved.

[0051] Alternatively, if Figure 4 As shown, a first baffle 322 is provided on the upper edge of the second port 321, and a second baffle 214 is provided on the top of the air outlet housing 2. The first baffle 322 and the second baffle 214 abut against each other to improve the positioning accuracy when the air outlet housing 2 and the air duct 3 are assembled.

[0052] Specifically, Figure 3 and Figure 4 As shown, the lower end face of the first baffle 322 and the end face of the second port 321 are located in the same plane, the air outlet housing 2 further includes a second baffle 214, the second baffle 214 is arranged on the side of the flat plate away from the air outlet channel 23, the second baffle 214 is arranged at the front end of the second convex edge 213 and is higher than the second convex edge 213, and the front end face of the first baffle 322 and the rear end face of the second baffle 214 are abutted. It can be understood that the lower end face of the first baffle 322 is coplanar with the end face of the second port 321, that is, the inclination angle of the lower end face of the first baffle 322 is consistent with the inclination angle of the second port 321.

[0053] When the air outlet housing 2 is assembled with the air duct 3, under the guiding action of the inclined surface of the second port 321 and the lower end surface of the first baffle 322, the air outlet housing 2 can be smoothly inserted into the housing 1 in the front-to-rear direction, thereby improving the convenience of assembling the components of the floor-standing air conditioner. In addition, the front end surface of the first baffle 322 abuts against the rear end surface of the second baffle 214. Therefore, the second baffle 214 can limit the position of the first baffle 322 to improve the accuracy of the assembly of the air outlet housing 2 and the air duct 3, and avoid the air leakage problem caused by the misalignment of the assembly of the second port 321.
