[0028] refer to Figure 1 In some embodiments, the indoor unit of the air conditioner includes a housing 4 and an evaporator assembly 1. The evaporator assembly 1 is located inside the housing 4.

[0029] In some embodiments, the housing 4 is a square housing. The indoor unit of the air conditioner also includes a first water receiving tray 5 and a second water receiving tray 6, which are respectively disposed on two adjacent sides of the square housing and are both located outside the evaporator assembly 1 to receive condensate generated by the evaporator assembly 1.

[0030] The indoor unit of the air conditioner also includes a fan 3, and the casing 4 has an air inlet and an air outlet. The evaporator assembly 1 is located inside the casing 4 near the air inlet, and the fan 3 is located inside the casing 4 near the air outlet. When the fan 3 operates, it creates a negative pressure, which draws air in through the air inlet of the casing 4, and after heat exchange through the evaporator assembly 1, it is blown out through the air outlet.

[0031] refer to Figure 2 and Figure 3 In some embodiments, the evaporator assembly includes a first evaporation section 12, a second evaporation section 13, and a connecting plate structure 11. The connecting plate structure 11 is used to connect the first evaporation section 12 and the second evaporation section 13. The connecting plate structure 11 includes a first connecting plate 111 and a second connecting plate 112. The first connecting plate 111 is connected to the first evaporation section 12. The second connecting plate 112 is connected to the second evaporation section 13. The first connecting plate 111 includes a main body portion 1111 for connecting to the first evaporation section 12 and an extension portion 1112 extending outward from the main body portion 1111 in the width direction.

[0032] The first connecting plate 111 of the connecting plate structure 11 includes an extension 1112. In some embodiments, condensate generated on the evaporator assembly falls into a drip tray through the extension 1112, effectively preventing condensate from dripping outside the drip tray. For example, in Figure 1 In the embodiment shown where the indoor unit of the air conditioner is placed longitudinally, the condensate produced by the evaporator assembly 1 is guided to the fins through the extension 1112, and then the condensate falls into the drip tray along the fins; for example, in Figure 4 In the embodiment shown where the indoor unit of the air conditioner is placed horizontally, the condensate generated by the evaporator assembly 1 flows into the second drip tray 6 along the extension 1112, which can effectively prevent the condensate from dripping outside the drip tray.

[0033] In other embodiments, at least one of the first connecting plate 111 and the second connecting plate 112 includes an extension. For example, if both the first connecting plate 111 and the second connecting plate 112 include an extension, then the condensate generated from the two evaporation sections can be drawn into the water receiving tray through the extensions on both sides.

[0034] In some embodiments, reference Figure 2The top ends of the first evaporation section 12 and the second evaporation section 13 are connected by a connecting plate structure 11 to arrange the evaporator assembly in a V-shape, with an included angle between the first connecting plate 111 and the second connecting plate 112. That is, the first connecting plate 111 and the second connecting plate 112 are inclined. Specifically... Figure 2 In the illustrated embodiment, the first connecting plate 111 is inclined, so that condensate flows along the surface of the extension 1112 into the water receiving tray.

[0035] refer to Figure 2 and Figure 3 In some embodiments, a gap exists between the top end of the first evaporation section 12 and the top end of the second evaporation section 13. The connecting plate structure 11 also includes an intermediate connecting plate 113, which is located between the first connecting plate 111 and the second connecting plate 112.

[0036] In some embodiments, reference Figure 3 The first connecting plate 111 includes a U-shaped structure, and the two side edges of the extension 1112 are recessed inward relative to the corresponding side edges of the main body 1111. Because the two side edges of the extension 1112 are recessed inward relative to the corresponding side edges of the main body 1111, air passing through the evaporator is diverted from both sides of the extension 1112, allowing insufficiently heated air to mix with fully heated air, thus lowering its temperature. This ensures that when the air is blown onto the upper fan 3, the air temperature does not reach the dew point temperature, preventing condensation from occurring on the fan 3.

[0037] In some embodiments, the extension 1112 is symmetrical with respect to the axis of the connecting plate structure 11. That is, the extension 1112 extends outward from the middle of the main body 1111. This arrangement ensures that the airflow from both sides of the extension is substantially the same, thereby facilitating uniform mixing of the air on both sides.

[0038] In some embodiments, reference Figure 3 The connecting plate structure 11 also includes a bent edge 114, which is disposed at the edge of the second connecting plate 112. The bent edge 114 can improve the strength of the structure 11 and reduce the noise generated by the unit when it is running at high wind speed.

[0039] In some embodiments, the axis A of the connecting plate structure 11 is in the same plane as the rotation axis of the fan 3, which effectively ensures that the flow distribution of the extension 1112 is more uniform.

[0040] The following is based on Figures 1 to 3 The structure of an air conditioner indoor unit according to a specific embodiment of the present invention will be described in detail.

[0041] like Figure 1As shown, the indoor unit of the air conditioner in this embodiment includes an evaporator assembly 1, a first drip tray 5, a second drip tray 6, a fan 3, and a housing 4. The evaporator assembly 1, the first drip tray 5, the second drip tray 6, and the fan 3 are all housed within the housing 4.

[0042] The housing 4 is a cuboid structure and includes an air inlet on the bottom and an air outlet on the top. A fan 3 is mounted on the top of the housing 4. Air enters the housing 4 through the air inlet, passes through the evaporator assembly 1, is blown onto the fan 3, and flows out through the air outlet. A first water collection tray 5 and a second water collection tray 6 are respectively provided on the bottom and one side of the housing 4. The first water collection tray 5 is located on the bottom of the housing 4, and the second water collection tray 6 is located on the side of the housing 4, with its bottom end abutting against the first water collection tray 5. The height of the second water collection tray 6 is higher than the height of the evaporator assembly 1.

[0043] The structure of evaporator assembly 1 is as follows Figure 2 As shown, the evaporator assembly 1 includes a first evaporator section 12, a second evaporator section 13, and a connecting plate structure 11 connecting the first evaporator section 12 and the second evaporator section 13. The first evaporator section 12 and the second evaporator section 13 are arranged at a certain angle to form a V-shape. A gap exists between the top ends of the first evaporator section 12 and the second evaporator section 13. The connecting plate structure 11 connects the first evaporator section 12 and the second evaporator section 13. The two evaporator sections in the evaporator assembly 1 are connected by the connecting plate structure 11 to form the evaporator assembly 1. Besides being connected to the evaporator connecting plate by screws, the evaporator assembly 1 can also be connected by snap-fit, welding, or other methods, offering multiple installation options and making installation simple and convenient.

[0044] The structure of the connecting plate structure 11 is as follows: Figure 3 As shown, the connecting plate structure 11 includes a first connecting plate 111, a second connecting plate 112, and an intermediate connecting plate 113 disposed between the first connecting plate 111 and the second connecting plate 112. The first connecting plate 111 is connected to the first evaporation section 12, and the second connecting plate 112 is connected to the second evaporation section 13. Furthermore, both the first connecting plate 111 and the second connecting plate 112 are inclined, and the included angle between the first connecting plate 111 and the second connecting plate 112 is an obtuse angle. The first connecting plate 111 includes a main body 1111 and an extension 1112. The main body 1111 covers and connects to the first evaporation section 12, and the extension 1112 extends outward from the main body 1111.

[0045] In this embodiment, the first connecting plate 111 is convex in shape, and the extension 1112 is located in the center of the main body 1111. Air passing through the evaporator is split from both sides of the extension 1112, changing the airflow and mixing the air that has not undergone sufficient heat exchange with the air that has undergone sufficient heat exchange, thus lowering its temperature. This ensures that when the air is blown onto the upper fan 3, the air temperature does not reach the dew point temperature, preventing condensation from forming on the fan 3. Figure 1 In the installation method, the condensate generated by the evaporator assembly 1 is guided to the fins through the extension 1112, and then the condensate falls into the water collection tray along the fins. Figure 4 In the installation method, the condensate generated by the evaporator assembly 1 flows into the second water receiving tray 6 along the extension 1112, which can effectively prevent the condensate from dripping outside the water receiving tray.

[0046] The connecting plate structure 11 in this embodiment also includes an intermediate connecting plate 113 located between the first connecting plate 111 and the second connecting plate 112. Both the first evaporation section 12 and the second evaporation section 13 in this embodiment have square structures with rectangular top surfaces. The main body 1111 of the first connecting plate 111 is also rectangular, the second connecting plate 112 is rectangular, and the intermediate connecting plate 113 is a strip plate. The extension 1112 is also square.

[0047] In embodiments not shown in the accompanying drawings, the shape of the connecting plate structure 11 is not limited; for example, the edges may be curved.

[0048] like Figure 2 As shown, in the width direction, the edge of the main body 1111 of the first connecting plate 111 extends beyond the top end face of the first evaporator 12. The edge of the second connecting plate 112 extends beyond the top end face of the second evaporator 13. Furthermore, the edge of the first connecting plate 111 is provided with a reinforcing edge, and the edge of the second connecting plate 112 is provided with a bent edge 114. The overlapping edge of the connecting plates provides reliable strength, and the unit will not generate noise when operating at high fan speed.

[0049] like Figure 3 As shown, the connecting plate structure 11 in this embodiment is symmetrical with respect to axis A. In some embodiments, the axis A of the connecting plate structure 11 and the motor shaft axis of the fan 3 are in the same plane to ensure more uniform flow distribution.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
