[0032] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described by referring to the drawings below are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0033] The air conditioner cabinet 100 of the embodiments of the present invention will be described below with reference to Figures 1-6 The air conditioner cabinet 100 generally includes: an evaporator 10, an air duct structure 20, and a cross-flow fan 30. Among them, the evaporator 10 is used for cooling or heating air, and the cross-flow fan 30 is disposed in the air cavity 21 and is used for driving air to enter the air cavity 21 after passing through the evaporator 10.

[0034] As Figure 1 Combined with Figure 2As shown in the figure, the air conditioner console 100 includes an evaporator 10 and an air duct structure 20. Among them, the air duct structure 20 defines an air outlet cavity 21, and the evaporator 10 is disposed on the air duct structure 20 and surrounds the air inlet side of the air cavity 21. That is to say, the evaporator 10 is assembled on the air duct structure 20, and the air duct structure 20 plays a role in supporting the evaporator 10. In other words, the evaporator 10 is connected to the air duct structure 20, and the cross-flow fan 30 is enclosed in the air cavity 21 of the air duct structure 20.

[0035] In short, for the air conditioner console 100 according to the embodiment of the present invention, by directly connecting the evaporator 10 to the air duct structure 20, there is no need to additionally provide a mounting bracket for assembling the evaporator 10, reducing the installation space inside the air conditioner console 100, and meeting the requirements of miniaturization and low cost of the air conditioner console 100.

[0036] In some embodiments of the present invention, as Figure 1 , Figure 4 and Figure 6 shown, the air duct structure 20 includes a top plate 23 and a bottom plate 25 which are arranged opposite to each other up and down and two side plates 22 connected between the top plate 23 and the bottom plate 25. One end of the evaporator 10 is connected to one of the side plates 22, and the other end of the evaporator 10 is connected to the other side plate 22. That is to say, the air cavity 21 with an inlet 26 and an outlet 27 is jointly defined by the top plate 23, the bottom plate 25 and the side plates 22, and both ends of the evaporator 10 are locked to the rear ends of the two side plates 22.

[0037] Among them, the connection manner between the evaporator 10 and the side plate 22 can be screw locking and / or pin locking. As Figure 1 shown, the side plate 22 is provided with positioning posts, and the side plate of the evaporator 10 is provided with screw holes.

[0038] In a further optional embodiment, the top plate 23 is provided with an upper extension plate 231, and the bottom plate 25 is provided with a lower extension plate 251. The evaporator 10 is clamped between the upper extension plate 231 and the lower extension plate 251. That is to say, when the evaporator 10 is assembled on the air duct structure 20, the upper extension plate 231 covers the upper end face of the evaporator 10, and the lower extension plate 251 covers the lower end face of the evaporator 10. In other words, the projections of the upper extension plate 231 and the lower extension plate 251 in the horizontal direction cover the projection of the evaporator 10 in the horizontal direction. In this way, the upper extension plate 231 can prevent the air flow in the air cavity 21 from flowing out from the upper side of the evaporator 10, and the lower extension plate 251 can prevent the air flow in the air cavity 21 from flowing out from the lower side of the evaporator 10. That is, the upper extension plate 231 and the lower extension plate 251 can prevent the air flow entering the air cavity 21 from flowing out through the fitting gap between the evaporator 10 and the air duct structure 20. Thereby, ensuring that the air conditioner console 100 has a stable air output and improving the refrigeration efficiency.

[0039] In a further optional embodiment, asFigure 3 Combination Figure 4 As shown, a wind deflector 2311 extending downward is provided on the bottom surface of the upper extension plate 231, and the inner side surface of the evaporator 10 is attached to the wind deflector 2311. In this way, on the one hand, the wind deflector 2311 can define the position of the evaporator 10 relative to the air duct structure 20, and on the other hand, the upper end of the evaporator 10 is attached to the wind deflector 2311, so that the upper end of the evaporator 10 is closely fitted with the air duct structure 20, avoiding the outflow of air from the connection between the evaporator 10 and the air duct structure 20.

[0040] In some alternative embodiments of the present invention, a supporting surface 2511 is provided on the top surface of the lower extension plate 251, the lower end surface of the evaporator 10 is press-fitted on the supporting surface 2511, a water diversion groove 25111 extending from the outside to the inside is provided on the supporting surface 2511, a drain groove 25112 is provided at the inner end of the water diversion groove 25111, and the water storage surface of the drain groove 25112 is lower than the water channel surface of the water diversion groove 25111.

[0041] As Figure 1 Combination Figure 3 As shown, the supporting surface 2511 is adapted to the shape of the evaporator 10. When the evaporator 10 is assembled on the air duct structure 20, the lower end of the evaporator 10 abuts against the supporting surface 2511. In this way, when the air conditioner cabinet 100 is operating, the condensed water formed on the evaporator 10 can flow into the water diversion groove 25111, and the water diversion groove 25111 introduces the condensed water into the drain groove 25112. There is a height difference between the drain groove 25112 and the water diversion groove 25111. Therefore, it is more conducive to the condensed water flowing into the drain groove 25112. A drain pipe 2512 can also be provided at the bottom of the lower extension plate 251, and the condensed water is discharged through the drain pipe 2512.

[0042] The water diversion grooves 25111 can be multiple ones distributed circumferentially along the lower extension plate 251, and the condensed water dripping from different positions of the evaporator 10 is collected into the drain groove 25112 through the multiple water diversion grooves 25111.

[0043] Further optionally, as Figure 1 Combination Figure 3 As shown, a water receiving groove 25113 is provided at the outer end of the water diversion groove 25111, the water receiving groove 25113 surrounds the outside of the supporting surface 2511, and the water channel surface of the water diversion groove 25111 is lower than the water storage surface of the water receiving groove 25113 or the water channel surface of the water diversion groove 25111 is flush with the water storage surface of the water receiving groove 25113. That is, an additional water receiving groove 25113 is provided around the supporting surface 2511, and the water receiving area is increased through the water receiving groove 25113 to prevent the condensed water from dripping outside the lower extension plate 251.

[0044] It should be noted that in the embodiments of the present invention, "inside" and "outside" are relative to the air duct 21. The side close to the air duct 21 is the inside, and the side far from the air duct 21 is the outside.

[0045] In a specific embodiment, as Figure 5 shown, the lower extension plate 251 extends obliquely from outside to inside. In this way, the water in the water receiving groove 25113 flows along the inclined surface into the water diversion groove 25111, and then flows along the inclined surface of the water diversion groove 25111 into the drainage groove 25112. This enables the condensed water to be quickly discharged from the air conditioner cabinet 100.

[0046] Further optionally, a water retaining platform 25114 is provided at the outer edge of the water receiving groove 25113, and the top surface of the water retaining platform 25114 is lower than the supporting surface 2511. In this way, the water retaining platform 25114 prevents the condensed water from flowing outwards, and facilitates the insertion of the evaporator 10 between the upper extension plate 231 and the lower extension plate 251, avoiding interference between the water retaining platform 25114 and the fins of the evaporator 10.

[0047] In some other embodiments of the present invention, the distance between the upper extension plate 231 and the lower extension plate 251 is H, and the height of the evaporator 10 is h, and H is greater than h. That is, the vertical height between the upper extension plate 231 and the lower extension plate 251 is greater than the height of the evaporator 10 in the vertical direction. Thus, it is convenient for the evaporator 10 to be clamped between the upper extension plate 231 and the lower extension plate 251, improving the assembly efficiency.

[0048] Further optionally, the downward extension distance of the wind deflector 2311 is L, and L ≥ (H - h). Where 0 < (H - h) ≤ 20 mm. For example, in one embodiment, (H - h) is taken as 6 mm and L is taken as 12 mm. Thus, on the one hand, it is beneficial to the assembly between the evaporator 10 and the air duct structure 20, and on the other hand, the wind deflector 2311 can be used to prevent the air flow from flowing out of the air duct 21, ensuring the air volume and improving the energy consumption.

[0049] In some other embodiments of the present invention, as Figure 6 shown, the air duct structure 20 includes a first air shell 28 and a second air shell 29. The rear end of the second air shell 29 is connected to the front end of the first air shell 28 to jointly form the air duct 21. Among them, the first air shell 28 defines the inlet 26 of the air duct 21, and the second air shell 29 defines the outlet 27 of the air duct 21. Both the first air shell 28 and the second air shell 29 are integrally formed parts.

[0050] That is, the air duct structure 20 of the embodiments of the present invention includes two parts, the first air shell 28 located at the rear side of the air duct structure 20 has an inlet 26, that is, cold air or hot air is introduced into the air duct 21 through the first air shell 28, and the second air shell 29 located at the front side of the air duct structure 20 has an outlet 27, that is, cold air or hot air is led out of the air duct 21 through the second air shell 29.

[0051] To improve the overall structural strength and assembly efficiency of the air duct structure 20, both the first air housing 28 and the second air housing 29 are integrally formed parts. In this way, during the assembly process of the air duct structure 20, the second air housing 29 can be directly assembled onto the first air housing 28 to complete the assembly of the air duct structure 20. In addition, to ensure the smoothness of the flow path in the air cavity 21, the front end of the first air housing 28 and the rear end of the second air housing 29 are in smooth transition. In this way, it is possible to avoid the formation of vortices of the air flow in the air cavity 21 and reduce the flow noise of the air flow.

[0052] In a further optional embodiment, the second air housing 29 is detachably arranged on the first air housing 28. It can be understood that in the case where the evaporator 10 is provided on the air inlet side of the air duct structure 20, during the assembly process, the cross-flow fan 30 can be first assembled into the air cavity 21, and then the second air housing 29 can be assembled onto the first air housing 28. When disassembling the cross-flow fan 30, the second air housing 29 can be first removed from the first air housing 28, and then the cross-flow fan 30 can be taken out from the air cavity 21.
