It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Embodiment one:

fig. 3 is a schematic structural diagram of an indoor unit light emitting assembly according to an embodiment of the present utility model; fig. 4 is a schematic structural diagram of a lamp box in an indoor unit lighting assembly according to an embodiment of the present utility model, in which a region where a light shielding portion is located is partially enlarged. As shown in fig. 3 to 4, an indoor unit lighting assembly according to an embodiment of the present utility model includes a lamp box 100, the lamp box 100 includes a lamp box body 110, a lighting member 120 and a light-transmitting cover 130, the lamp box body 110 has a front wall 111, and the lighting member 120 is located at a top of a space in the lamp box body 110 and is close to the front wall 111; the light-transmitting cover 130 covers the top of the lamp box body 110; the top of the front wall 111 is provided with a light shielding portion 112 extending upwards, the light shielding portion 112 is made of a light shielding material, the light shielding portion 112 covers at least part of the front surface of the light-transmitting cover 130, and the light shielding portion 112 is arranged corresponding to the light emitting member 120.

Generally, a side of an indoor unit of a cabinet air conditioner facing an indoor space or a personnel active area in a room is a front side of the indoor unit of the cabinet air conditioner; and the side of the cabinet air conditioner indoor unit facing the corner or the wall is the rear side of the cabinet air conditioner indoor unit. That is, the definition of "front" and "rear" in the present utility model is that, when the cabinet air conditioner indoor unit is air-out, the downstream in the air-out direction is the front, and the upstream in the air-out direction is the rear. In the present utility model, the inner side of each component means the side of the component facing the fan of the indoor unit of the cabinet air conditioner. Accordingly, a front side facing panel of the casing of the indoor unit of the cabinet air conditioner is a front decorative panel 300.

Specifically, in the present embodiment, the light shielding portion 112 may extend upward from the middle of the top of the front wall 111. In another implementation, the light shielding part 112 may also extend upward from the entire length of the top of the front wall 111 to more fully shield the light of the light emitting element 120 refracted through the front surface of the light-transmitting cover 130.

Here, the light shielding portion 112 is provided corresponding to the light emitting element 120, which means that, in the case where the light shielding portion 112 does not extend upward from the top end thereof in the entire width direction of the front wall 111, the position of the light shielding portion 112 corresponds to the position of the light emitting element 120 in the width direction of the front wall 111. For example, the light emitting member 120 is located at the widthwise middle of the front wall 111, and then the light shielding portion 112 is also located at the widthwise middle of the front wall 111, accordingly.

In addition, in the present embodiment, the light shielding portion 112, like the front wall 111 of the lamp box body 110, may be made of opaque material with black color, so that the light emitted by the light emitting element 120 directly and refracted by the light transmitting cover 130 is at least partially blocked and not directly emitted to the inner side of the front decorative board 300 of the cabinet air conditioner indoor unit.

By providing the light shielding portion 112 extending upward at the top of the front wall 111, light refracted by the front surface of the light-transmitting cover 130 can be blocked by the light shielding portion 112 when light emitted from the light-emitting member 120 propagates through the light-transmitting cover 130. Further, since the light emitting element 120 is close to the front wall 111, a large light shielding portion 112 is not required, and a main portion of the light refracted by the light emitting element 120 toward the front surface of the light transmitting cover 130 through the light transmitting cover 130 can be shielded. Even if there is an uncovered portion, since the angle between it and the front-rear direction is large, the path is long when it propagates in the light-transmitting cover 130, and the light intensity is greatly reduced, so the light intensity striking the front surface of the light-transmitting cover 130 is weak, and thus the inner side of the front decorative plate 300 is not significantly illuminated, and finally, the user experience can be improved.

As shown in fig. 4, it is preferable that the front surface of the light-transmitting cover 130 is provided with a receiving notch in which at least part of the light-shielding portion 112 is received.
