For example, the uniform light plate 36 can be in the shape of a translucent plate, and is used to convert the line light source or point light source emitted by the light plate assembly 31 into a surface light source. The light emitted by the lamp board assembly 31 becomes softer through the uniform light effect of the light distribution plate 36 and the dispersion effect of the light transmission hole 32 . Protect the user's eyes from being stimulated by strong light and make the user's eyes more comfortable.

In some embodiments of the present invention, as specifically shown in FIGS. 6 to 7 , the handle body 34 includes a light-emitting portion 340 , a “U”-shaped mounting portion 342 and a connecting plate portion 344 .

Wherein, the front surface of the light-emitting portion 340 is disposed outwardly and is provided with the aforementioned plurality of light-transmitting holes 32, the top surface or bottom surface of which abuts against the vertical end surface (referring to the upper end surface or the lower end surface) of the door body 20. to form a contact surface. When the handle 30 is located at the top of the door body 20 , the bottom end of the light-emitting portion 340 abuts against the upper end surface of the door body 20 . When the handle 30 is located at the bottom end of the door body 20 , the bottom end of the light-emitting portion 340 abuts against the lower end surface of the door body 20 . The accommodating cavity 33 is formed in the light emitting part 340 .

In the embodiment of the present invention, the front surface of the light-emitting portion 340 is disposed outward and has a plurality of light-transmitting holes 32, so that the user can directly hold the bright light, that is, the handle 30, in a dark environment. On this basis, the light-transmitting hole 32 can also be set at the center position of the light-emitting portion 340 or the center position is biased toward the opening position of the door body 10 , because this position is the most accustomed position for general users to hold.

The opening direction of the "U"-shaped mounting portion 342 faces away from the door body 20 so as to be embedded in the door body 20 , and the front edge of the opening is in contact with the rear edge of the abutting surface. For example, in FIGS. 4 and 8 , the handle 30 is located at the bottom end of the door body 20 , so that the opening of the “U”-shaped mounting portion 342 faces downward. The bottom end of the door body 20 is recessed inward to accommodate the "U"-shaped mounting portion 342 .

The end of the “U”-shaped mounting portion 342 embedded in the door body 20 forms a lateral end (left end) with a “U”-shaped groove recessed into the door body 20 and extending laterally toward the other lateral end (right end). Because the "U"-shaped mounting portion 342 penetrates both sides of the end face of the door body 20 , the user's hand can open the door body from any position on the end of the door body 20 .

The connecting plate portion 344 is bent and extended backward from the opening rear edge of the “U”-shaped mounting portion 342 so as to be fastened to the door body 20 . The connecting plate portion 344 is bent and extended backward from the opening rear edge of the “U”-shaped mounting portion 342 so as to be fastened to the door body 20 .

The weight is lighter, and the weight of plastic is less than that of metal under the same volume, so the handle 30 made of plastic is lighter in weight and convenient for transportation. The handle 30 made of plastic only needs one injection molding, which has certain advantages compared with the multiple processing and processing cost of metal. More environmentally friendly and economical, the handle 30 made of plastic can be recycled to save energy. The light transmittance is better, and plastic products are generally transparent or translucent. The handle 30 made of plastic can irradiate the light emitted by the lamp board assembly 31 to the handle 30 without disposing the light-transmitting hole 32 on the surface of the handle body 34. external.

In some embodiments of the present invention, as shown in FIG. 1 and FIG. 2 , the lateral end profile of the handle 30 is that both the front and rear sides extend vertically, and the upper and lower sides are gradually from the back to the front to the vertical center of the door body. A parallelogram with an inclined direction. In this embodiment, the refrigerator is a side-by-side refrigerator with four upper and lower door bodies 10 . The vertical end face (referring to the upper end face or the lower end face) of the door body 10 has a handle 30 .

In this way, the lower surface of the handle 30 of the upper door body 10 of the refrigerator and the upper surface of the handle 30 of the lower door body 10 of the refrigerator form a "V"-like space, which is convenient for the user's hand to insert into the handle 30 and quickly pass through the handle 30.
