[ detailed description ] embodiments
In one embodiment, the door 100 of the washing machine is provided with the light emitting module 10. The light emitting module is shown in fig. 1 and includes a base 2, a light source 4 and a light shield 6. The light source 4 is located between the base 2 and the light shield 6.
As shown in fig. 3A and 3B, a ring of positioning walls 22 and a plurality of positioning pillars 24 disposed near the positioning walls 22 are disposed on the base 2. Positioning column 24 and positioning wall 22 have a gap therebetween, so that light source 4 is clamped therebetween for fixing.
As shown in fig. 2A and 2B, the light shield 6 covers the base 2 and the light source 4, and abuts against the positioning wall 22. The base 2 has a diffusely reflective region 26 that receives illumination from the light source 4. The diffuse reflection area 26 is a curved structure curved toward the light source 4 and the light shield 6. A space is provided between the base 2 and the light shield 6, and a light-transmitting region 8 is formed in the space. The light-transmitting area 8 is located outside opposite to the diffuse reflection area 26. The light shield 6 comprises a light-shielding area 62 made of an opaque material. The light-shielding region 62 shields the entire light source 4 from the outside to prevent the light emitted from the light source 4 from being directly radiated to the outside of the light-shielding cover 6. Therefore, the light emitted from the light source 4 can only pass through the light-transmitting area 8 after being reflected by the diffuse reflection area 26, and thus can be observed from the outside of the door body 100 by human eyes.
The light emitting module 10 is covered by a light-permeable protective cover 12. The protective cover 12 also closes the gap between the base 2 and the light shield 6, so that a closed light-emitting chamber 40 is formed between the base 2, the light shield 6 and the protective cover 12. The light source 4 is housed in the light emitting chamber 40 and protected from water and dust.
In this embodiment, the light source 4 is a LED strip closed into a ring. The light-transmitting region 8 is a band-like structure extending at an equal distance from the light source 4. As can be seen from fig. 2A, in the present embodiment, the light-transmitting region 8 also forms a closed annular belt-like structure. And the light-transmitting region 8 is close to the door body edge.
As shown in fig. 1, the light emitting module 10 is annular as a whole and forms a part of the door body.
In addition, the washing machine comprises a control device (not shown in the figures) connected to the light source 4. The control device is provided to control the light emission color, switching frequency, brightness, and brightness variation of the light source 4. Thus, under the action of the control means, the light source 4 can emit light in various forms and be presented to the user through the light-transmitting area 8. The various forms of light may include color variations, light and shade variations, flickering and the like.
