[ detailed description ] embodiments

Referring to fig. 1 to 4, the present invention provides an air conditioning indoor unit 100, including a base 10, an indoor unit 20 assembled on the base 10, and an outer cover 30 assembled on the base 10 and covering the indoor unit 20, wherein the indoor unit 20 includes an evaporator 201 and a fan 202, the outer cover 30 is provided with an air inlet 301 and an air outlet 302, the outer cover 30 is provided with a plurality of horizontally disposed air inlet grilles 303 at the air inlet 301, and the air inlet grilles 303 have a C-shaped cross section with an opening facing the indoor unit 20. The air inlet grille 303 having a C-shaped cross section with an opening facing the indoor unit enhances blocking of condensed water which may be splashed out, improves, and meets user experience.

The intake grill 303 having a C-shaped cross section includes a body portion 3031, an upper wing 3032 extending inward from an upper end of the body portion 3031, and a lower wing 3033 extending inward and downward from a lower end of the body portion 3031, wherein the lower wing 3033 extends into the intake opening 301 more than the upper wing 3032. The above design is to ensure that water in the lower row of the intake grilles 303 can be received by the upper row of the intake grilles 303 in an inclined state, and meanwhile, a structure similar to an eave is formed, so that condensed water is prevented from being discharged from the intake grilles 303. The included angle alpha between the lower wing 3033 and the horizontal plane is 20-45 degrees, so that the water splashing prevention effect in a horizontal state and an inclined state is considered. The upper wing 3032 horizontally extends inward from the upper end of the body portion 3031. The inner side of the C-shaped cross section is a bowl-shaped accommodating part 3034, and the two adjacent rows of the air inlet grilles 303 are configured as follows: referring to fig. 4, when the air conditioning indoor unit 100 is tilted forward by 35 degrees (β =35 degrees), the projection of the free end of the upper row of the lower wing 3033 in the direction of gravity falls on the bowl-shaped receiving portion 3034 of the lower row of the lower wing 3033. By the design, the waterproof effect in the forward tilting state can be realized.

The outer cover 30 has a front cover 31, the air inlet 301 and the air outlet 302 are disposed on the front cover 31, the air outlet 302 is located above the air inlet 301, and the indoor unit 100 of the air conditioner further includes a water collection tray 40 located below the indoor unit 20. The air outlet 302 is located above the air inlet 301, so that the air inlet 301 is close to the water collecting tray 40 below the indoor unit 20, the activity space of water during splashing is shortened, and the water is quickly recovered into the water collecting tray 40. The front cover 31 has a guide plate 304 for directly or indirectly guiding the condensed water in the bowl-shaped receiving part 3034 to the water collecting tray 40. The guiding plate 304 in this embodiment is disposed at the lowest part of the front cover to receive the condensed water from the free end of the upper wing 3032 and guide the condensed water to the water collecting tray 40; of course, in other embodiments, the lower wing 3033 may continue to extend rearward, but may be relatively less manufacturable. The indoor unit 100 of the air conditioner includes a rear cover 32 opposite to the front cover 31, and two side covers 33 connecting the front cover 31 and the rear cover 32, and a waterproof flow guiding layer (not shown) for collecting condensed water to the water collecting tray 40 is disposed on inner walls of the rear cover 32 and the two side covers 33. And also. The indoor air conditioner 100 described in this embodiment is specifically an indoor air conditioner for a vehicle, and can obtain a higher anti-splashing effect in a complex vibration environment.

In summary, the above description is only for the preferred embodiment of the present invention, and certainly not limited thereto. All the equivalent changes and modifications made according to the claims and the contents of the specification of the present invention should still fall within the scope covered by the present invention.
