[0022] 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.
[0023] As Figure 1 shown, the air duct structure of the embodiment of the present utility model includes an air duct body 1. The material of the air duct body 1 can be plastic, and the air duct body 1 can be integrally formed by injection molding. During assembly, the air duct body 1 can be installed on the front side of the base of the air conditioning equipment. The air duct body 1 can generally extend along the up and down direction, and the air duct body 1 can generally extend along the left and right direction, that is, the length direction of the air duct body 1 can be the left and right direction.
[0024] One convex 11 or at least two convexes 11 are provided on the inner wall surface of the air duct body 1. The at least two convexes 11 are arranged at intervals along the first direction. The convex 11 extends along the second direction orthogonal to the first direction, and the convex 11 is used to change the flow direction of the condensate flowing along the inner wall surface so that the condensate can be discharged to the heat exchanger 2 located below the air duct body 1.
[0025] For example, as Figure 1 shown, the first direction can be the up and down direction, and the second direction can be the length direction of the air duct body 1, that is, the second direction can be the left and right direction.
[0026] The convex 11 can specifically be a convex rib. The convex 11 can be integrally formed on the inner wall surface of the air duct body 1, where the inner wall surface is Figure 1 the front wall surface of the air duct body 1 in the middle. Only one convex 11 can be provided. In some other embodiments, two, three, four or other numbers of convexes 11 can also be provided. At this time, the multiple convexes 11 can be arranged at intervals along the up and down direction, and each convex 11 can extend along the left and right direction.
[0027] During assembly, as Figure 2 shown, the heat exchanger 2 of the air conditioning equipment can be installed on the front side of the air duct body 1 and at the bottom of the air duct body 1. The above-mentioned multiple convexes 11 can all be located above the heat exchanger 2.
[0028] During use, the external air can flow through the heat exchanger 2 along the air duct from the air inlet on the bottom side of the air conditioning equipment, and then can be discharged from the air outlet on the top side and in front of the air conditioning equipment. Since the chamber in the air duct body 1 is a cold chamber during use, the water vapor in the air duct body 1 will condense and liquefy to form condensate. The condensate will adhere to the inner wall surface of the air duct body 1 and flow along the direction from top to bottom.
[0029] Since a plurality of protrusions 11 are provided on the inner wall surface of the air duct body 1, the plurality of protrusions 11 can play a role similar to that of an eave, that is, the protrusions 11 can play a role in diverting and changing the flow direction of the condensed water, so as to facilitate dripping the condensed water droplets onto the heat exchanger 2 and finally collecting them in the water receiving tray at the bottom of the evaporator.
[0030] The air duct structure of the embodiment of the present utility model is provided with a plurality of protrusions 11, and the protrusions 11 can play a guiding role, thereby avoiding the situation where the condensed water drips outside the heat exchanger 2 and facilitating the collection of the condensed water.
[0031] Secondly, the setting of the protrusions 11 can also play a role in enhancing the overall structural strength of the air duct structure, that is, the protrusions 11 can play an effect similar to that of a reinforcing rib, thus fully meeting the usage requirements.
[0032] In some embodiments, the inner wall surface of the air duct body 1 is provided with a plurality of curved surfaces 12, and the plurality of curved surfaces 12 are arranged at intervals along the first direction, and the protrusions 11 are arranged between two adjacent curved surfaces 12 among the plurality of curved surfaces 12.
[0033] For example, as Figure 1 and Figure 2 shown, three curved surfaces 12 can be provided on the inner wall surface, the three curved surfaces 12 can be arranged in sequence along the up-down direction, and a protrusion 11 can be provided between every two adjacent curved surfaces 12. The protrusion 11 is a convex rib and can be constructed by designing two adjacent curved surfaces 12 with different curvatures.
[0034] During use, the condensed water can flow through each curved surface 12 in sequence along the up-down direction, thus facilitating the downward flow of the condensed water, and also being beneficial to reducing the wind resistance and facilitating the flow of the air flow.
[0035] In some embodiments, the curvature of at least some of the plurality of curved surfaces 12 gradually increases along the direction approaching the heat exchanger 2. For example, the curvature of the plurality of curved surfaces 12 can gradually increase along the up-down direction. Thus, the bottom of the air duct body 1 can gradually approach the heat exchanger 2 at the bottom, so as to facilitate gradually diverting the condensed water to the heat exchanger 2 and reducing the influence of the shape change of the air duct body 1 on the air flow.
[0036] In some embodiments, as Figure 1 and Figure 2As shown, the multiple curved surfaces 12 include a first curved surface 121 and a second curved surface 122. Both the first curved surface 121 and the second curved surface 122 can be arc surfaces. The second curved surface 122 is connected to one side of the first curved surface 121 adjacent to the heat exchanger 2, that is, the second curved surface 122 can be connected to the lower side of the first curved surface 121, and the curvature of the second curved surface 122 is greater than that of the first curved surface 121. Thus, while reducing the number of curved surfaces 12 to the minimum, the function of guiding the flow can be achieved, and it also plays a role in simplifying the overall structural style of the air duct body 1 and facilitating processing and forming.
[0037] In some embodiments, the multiple curved surfaces 12 include a third curved surface 123. The third curved surface 123 is connected to one side of the second curved surface 122 adjacent to the heat exchanger 2. In the third direction, the protrusion 11 between the second curved surface 122 and the third curved surface 123 protrudes toward the side of the second curved surface 122 facing the heat exchanger 2, and the third curved surface 123 extends away from the side of the second curved surface 122 facing the heat exchanger 2. The third direction is perpendicular to the first direction and the second direction.
[0038] For example, as Figure 2 shown, the third curved surface 123 can be connected below the above-mentioned second curved surface 122. The third direction can be the front-back direction. The protrusion 11 between the second curved surface 122 and the third curved surface 123 can be the following second protrusion 112. The heat exchanger 2 as a whole can be located on the front side of the air duct body 1. The second protrusion 112 can be provided on the front wall surface of the air duct body 1 and protrude forward. The third curved surface 123 is generally located on the rear side of the second curved surface 122, and the third curved surface 123 generally extends along the direction from the lower rear to the upper front.
[0039] Since the part of the air duct body 1 at the rear side of the heat exchanger 2 is arranged in a dislocation manner with the above-mentioned second curved surface 122 in the front-back direction, the third curved surface 123 can play a role in connecting the part of the air duct body 1 at the rear side of the heat exchanger 2 and the second curved surface 122 in a transitional manner, thus ensuring the integrity of the air duct body 1 and enabling the overall structural style of the air duct body 1 to match the assembly of the heat exchanger 2.
[0040] In some embodiments, in the third direction, both the first curved surface 121 and the second curved surface 122 protrude away from the heat exchanger 2, and the third curved surface 123 protrudes toward the heat exchanger 2.
[0041] For example, as Figure 2 shown, both the first curved surface 121 and the second curved surface 122 can be arc surfaces, and both the first curved surface 121 and the second curved surface 122 can protrude backward. The third curved surface 123 can be an irregular curved surface 12. The third curved surface 123 is generally V-shaped and can protrude forward.
[0042] In actual use, the first surface 121 and the second surface 122 mainly serve to guide the flow of condensed water, while the third surface 123 mainly serves for sealing connection and transition. This can simplify the structure and processing technology of the third surface 123, and also enables a part of the third surface 123 to fit well with the top of the heat exchanger 2, thus playing a good limiting role.
[0043] In some embodiments, as Figure 2 shown, the protrusion 11 between the first surface 121 and the second surface 122 is the first protrusion 111, and the protrusion 11 between the second surface 122 and the third surface 123 is the second protrusion 112. Both the first protrusion 111 and the second protrusion 112 can be in the shape of convex ribs, and in the first direction, the projections of the first protrusion 111 and the second protrusion 112 are both within the projection range of the heat exchanger 2, that is, in the up-down direction, the projections of the first protrusion 111 and the second protrusion 112 are both within the contour range of the projection of the heat exchanger 2 in the up-down direction.
[0044] Thus, the first protrusion 111 and the second protrusion 112 can be located directly above the heat exchanger 2, so that the condensed water blocked and diverted by the first protrusion 111 and the second protrusion 112 can directly drip onto the heat exchanger 2 below, further avoiding the situation of condensed water dripping outside the heat exchanger 2.
[0045] In some embodiments, the ratio of the curvature of the first surface 121 to the curvature of the second surface 122 is one-half. For example, the radius of the first surface 121 can be 60 cm, and the radius of the second surface 122 can be 30 cm. Since the curvature is the reciprocal of the radius of the corresponding circle, the ratio of the two can be obtained as one-half. Thus, under this condition, the drainage effect can be fully guaranteed, and the influence on the wind resistance can also be reduced.

The duct structure can be the duct structure described in any of the above embodiments. The air-conditioning equipment can be an indoor unit of an air conditioner, as Figure 2 shown, the heat exchanger 2 is arranged below the protrusion 11 of the duct body 1.

In some embodiments, as Figure 2 shown, the heat exchanger 2 can generally be V-shaped, and a water receiving tray can be provided at the bottom of the heat exchanger 2, so as to collect the condensed water on the heat exchanger 2.
