[0031] like Figure 1-5 As shown, the present disclosure provides a refrigerator door, which includes:
[0032] A transparent display screen assembly 15, a first molecular sieve 6, a light guide plate 7 and a backlight source 14, wherein the first molecular sieve 6 is a ring structure with a cavity formed inside, the transparent display screen assembly 15 is arranged in the cavity, the light guide plate 7 is connected to one side of the first molecular sieve 6 and is spaced apart from the transparent display screen assembly 15, and the backlight source 14 is arranged on the inner peripheral wall of the first molecular sieve 6, the vertical normal direction of the light-emitting surface of the backlight source 14 intersects with the light-guiding surface of the light guide plate 7, and the light-guiding surface is arranged opposite to the transparent display screen assembly 15, so that the light emitted by the backlight source 14 passes through the light guide plate 7 and is reflected onto the transparent display screen assembly 15.
[0033] The present invention sets a first molecular sieve, a light guide plate and a backlight source, and sets the backlight source on the inner wall of the first molecular sieve. The light is directed toward the light guide plate behind the screen. The light guide plate can change the line light source into a surface light source, so that the light is evenly emitted to the light guide plate and reflected onto the transparent display screen, which effectively enables the user to observe the content displayed on the transparent display screen, and also effectively avoids the phenomenon of glare caused by setting the backlight source inside the refrigerator compartment of the refrigerator when the refrigerator door is opened. The present invention sets the backlight source on the molecular sieve inside the refrigerator door and provides a backlight source for the transparent liquid crystal display screen, so that the user has a good visual experience when watching videos and other images through the liquid crystal display screen.
[0034] In some embodiments, there is an angle α between the plane on the inner wall of the first molecular sieve 6 where the backlight source 14 is set and the light guide surface of the light guide plate 7, and the value range of α is 0<α<90°. Preferably, it is 75°. This is a further preferred structural form of the first molecular sieve disclosed in the present invention. By setting the inner wall plane where the backlight source is set to have an acute angle α with the light guide surface, the light emitted by the backlight source can be effectively projected onto the light guide plate, and reaches the position of the transparent display screen through effective reflection from the light guide plate, so that the information on the transparent display screen is effectively displayed, thereby improving the display effect of the transparent display screen.
[0035] In some embodiments, a one-way perspective film 16 is further provided on the light guide surface of the light guide plate 7, a first side surface of the one-way perspective film 16 is in contact with the light guide surface, and a second side surface is opposite to the transparent display screen assembly 15, and a reflectivity of the one-way perspective film 16 to light incident on the second side surface is greater than or equal to 75%. The present disclosure also enhances the reflectivity of light projected onto the one-way perspective film and enhances the display effect of the transparent display screen by providing the one-way perspective film on the light guide plate.
[0036] In some embodiments, the one-way perspective film 16 allows light to completely pass through from the first side surface to the second side surface; and / or the one-way perspective film 16 includes an aluminum-plated film. The present disclosure also provides a one-way perspective film disposed on the light guide plate, which completely passes light from the inside of the refrigerator to the outside of the refrigerator, and can further enhance the light display effect of the transparent display screen.
[0037] In some embodiments, the inner wall of the backlight source 14 of the first molecular sieve 6 is provided with a plurality of heat dissipation holes 61; and / or the transparent display screen assembly 15 is a liquid crystal display screen assembly. The present disclosure sets the backlight source on the first molecular sieve, effectively eliminating the structure of the "lamp holder", which is simple and simplified, and adds heat dissipation holes on the aluminum frame outside the molecular sieve bar assembly to diffuse the heat generated by the long-term lighting of the light source and facilitate the volatilization of heat.
[0038] Figure 5 This is a screenshot of the outer aluminum frame of the molecular sieve strip assembly. The features are: first, it has a 75° inclination angle, which serves as the base of the light source; second, there are heat dissipation holes on the inclined surface where the molecular drying strip contacts the light source. When the screen is lit for a long time, the screen and the light source generate a lot of heat, which is dissipated through the heat dissipation holes. In addition, the heat generated can evaporate the moisture in the "zeolite" in the molecular drying strip assembly to avoid condensation on the glass door body.
[0039] In some embodiments, the first molecular sieve 6 is filled with a first water-absorbing material inside the structure, and when a heat dissipation hole is included, the first molecular sieve 6 is connected to the heat dissipation hole 61. And by filling the first water-absorbing material inside the first molecular sieve, moisture can be effectively absorbed, so that the air around the display screen remains dry, and condensation and the like are avoided. By filling the second water-absorbing material inside the second molecular sieve, moisture can be further effectively absorbed, so that the air around the display screen remains dry, and condensation and the like are avoided.
[0040] In some embodiments, the first water-absorbing material is zeolite, which is the preferred type and structural form of the first water-absorbing material disclosed in the present invention, and can effectively absorb water and dry.

The first glass can be provided to protect and provide perspective for the transparent display screen, and the inert gas can be filled between the first glass and the light guide plate to improve the thermal insulation performance around the transparent display screen, glass, etc., to prevent heat exchange with the outside world, thereby preventing condensation, etc.

[0043] In some embodiments, a second molecular sieve 8 is further disposed between the second glass 10 and the light guide plate 7, and a second water-absorbing material is also filled inside the structure of the second molecular sieve 8. The second molecular sieve can effectively separate the second glass and the light guide plate, and absorb and dry the space to prevent condensation.
[0044] In some embodiments, the second water-absorbing material is zeolite, which is the preferred type and structural form of the second water-absorbing material disclosed in the present invention, and can effectively absorb water and dry.
