Fig. 1 to 6 show an embodiment of an air conditioning indoor unit according to the present invention. Fig. 1 is a schematic partial structural view of an air conditioning indoor unit according to an embodiment of the present invention.

Referring to fig. 1, the air-conditioning indoor unit provided in this embodiment includes a casing 100 and a display box 200, wherein a display window (filled with the display box 200 and not labeled) is disposed on the casing 100, and a display screen 220 of the display box 200 is exposed at the display window. Wherein, the display window can be round, rectangular or polygonal; the shape of the corresponding display screen 220 may also match the periphery of the display window, or may be a circle, a rectangle, a polygon, etc. contained in the display window. In this embodiment, the shape of the display screen 220 matches the shape of the display window, is circular, and is located at the front end of the indoor unit of the air conditioner.

FIG. 2 is a schematic view of the structure of the display case of FIG. 1; fig. 3 is a schematic view of an exploded structure of the display case of fig. 2.

Referring to fig. 2 and fig. 3 in combination, the display box 200 includes a display panel 210 located at a front end, the display panel 210 includes a transparent display screen 220, and the display screen 220 is exposed at a display window of the indoor unit of the air conditioner. The display screen 220 includes a display area 221 and a connection area 222 surrounding the display area 221. The display area 221 is used for displaying information, and the connecting area 222 protrudes towards the front to form a light-transmitting rib 223.

The light-transmitting ribs 223 may be in the shape of a ring connected end to end, a polygon connected end to end, a broken C, or the like. The cross-sectional shape of the light-transmitting ribs 223 may be circular, semicircular, rectangular, trapezoidal, or other polygonal shapes, etc.

In order to solve the technical problems mentioned in the background art, in the display box 200 provided in the present embodiment, the light-transmitting ribs 223 are disposed on the connection regions 222, so that after light is refracted, reflected and projected in the light-transmitting ribs 223, a light-emitting effect different from that of the display region 221 is formed, and thus, the display between the display region 221 and the connection regions 222 has color difference, so that the color is richer.

Preferably, the light-transmitting ribs 223 are in a circular ring shape connected end to end; the light transmitting ribs 223 include an outer annular surface 224 and an inner annular surface 225. Because the printing opacity rib 223 is end to end's ring form, then light can be at printing opacity rib 223 internal reflection and circumference circulation transmission to make printing opacity rib 223's light-emitting more even, reach the even effect of gloss ability.

Preferably, the light-transmitting ribs 223 are formed on the periphery of the connection region 222, so as to be opposite to the edge of the display window, thereby achieving the effect of limiting the position of the display box 200 in the display window.

Referring to fig. 4 and 5 in combination, fig. 4 is a schematic cross-sectional view taken along the direction a-a in fig. 2; fig. 5 is an enlarged schematic view of the region C in fig. 4. Preferably, the included angle between the outer annular surface 224 and the inner annular surface 225 is acute, i.e. the projection of the cross-sections of the two intersect in a V-shape. So that the light is reflected multiple times at the outer and inner

annular surfaces

224 and 225 to be more uniform. Preferably, the outer annular surface 224 and the inner annular surface 225 are connected by a circular arc surface with a radius of 0.1mm to 5mm, so that the light emitted from the front end of the light-transmitting rib 223 is softer, and when a user views the light-transmitting rib 223 in a direction opposite to the front-back direction, a magnifying effect can be obtained.

Preferably, the front end of the inner ring surface 225 inclines towards the outer ring surface 224, and the included angle between the front end and the rear direction is alpha 1, and alpha 1 is more than 0 degree and less than or equal to 85; the front end of the outer annular surface 224 is inclined toward the inner annular surface 225, and an included angle between the front end and the rear end is alpha 2, wherein alpha 2 is more than 0 degree and less than or equal to 30 degrees. Within the above-mentioned range of angles, the color change can be made larger, especially when the back of the light-transmitting ribs 223 is coated with a colored film, the user can observe that the whole light-transmitting ribs 223 are colored.

Preferably, the touch surface of the display area 221 is shaped like an arc with a lower left and a higher middle right. On the one hand, the arc-shaped structure can reduce the touch area of a user and enable the fingers of the user to slide more conveniently. On the other hand, the display content in the display area 221 can be enlarged, so that the display content is easier for the user to observe.

Preferably, the wall thickness of the display area 221 at the central position and the wall thickness of the peripheral position are set differently. Because, when light passes through the transparent material with thick wall, different light-emitting effects can be generated. Therefore, in this embodiment, the wall thickness of the display region 221 is set to be variable, so that the display region 221 can also generate different light emitting effects, and the light emitting effect is enriched.

For example, please refer to fig. 6 in combination, fig. 6 is a schematic cross-sectional view along the direction B-B in fig. 2. The touch surface of the display area 221 includes a flat area 226 located in the middle and two arc areas 227 respectively connected to the upper and lower sides of the middle, and the arc areas 227 are formed recessed with respect to the flat area 226. In this embodiment, the arc 227 can also generate a certain zooming-in or zooming-out effect, so that the display effect is richer. Of course, in other embodiments, the touch surface of the display area 221 may be planar.

Preferably, a first film (not labeled) is disposed on the back side and/or the touch side of the display area 221, and the first film is an opaque film with a plurality of identification patterns engraved thereon; these identification patterns may include a power on/off icon, a mode icon, an air volume icon, a temperature icon, or other patterns. The back and/or touch side of the connecting region 222 is provided with a second film (not labeled), which is:

an opaque film connected to the first film; or a light-transmissive film adjacent to the first film; or a metallic texture film contiguous with the first film.

When the second film is the opaque film connected with the first film, the second film can generate the same effect as the first film; if the mark pattern is arranged, the light can be transmitted, and if the mark pattern is not arranged, the light cannot be transmitted. Wherein, the first film and the second film can be arranged separately; when the first film and the second film are both arranged on the back surface or the touch surface, the first film and the second film can also be integrally arranged.

When the second film is a transparent film adjacent to the first film, light can generate a transparent effect when passing through the transparent film, and further color light with the same color as the transparent film can be generated.

When the second film is a metal film adjacent to the first film, the light cannot penetrate through the metal film; and under the light reflection and light refraction effects of the light-transmitting ribs 223, the light-transmitting ribs 223 can generate metal effects similar to those of electroplating. Wherein the metallic texture can be golden, white silver or brass, etc.

Preferably, the display box 200 further includes a rear cover 230 covering the display panel 210, and a touch film 240, a display lamp cover 250 and a display circuit board 260 are disposed between the display panel 210 and the rear cover 230.

The display circuit board 260 is fixed to the rear cover plate 230 for emitting light.

The lampshade is covered on the front side of the television circuit board and used for diffusing light.

The touch film 240 is disposed between the lamp housing and the display panel 210, and is used for generating different control signals when different regions are pressed.

In this embodiment, by adding the touch film 240, a user can perform touch control, so that the operation scheme is richer. Of course, solid keys, such as 6 cylindrical keys of 3 × 2 in fig. 2, may be added.
