[0030] In some cases, a refrigerator is a refrigeration device that maintains a constant low temperature, and is also a product that keeps food or other items at a constant low temperature. During operation, the refrigerator may open the air duct damper to supply air, thereby promoting the circulation of air in the refrigerator. However, the refrigerator air duct currently has no explicit design and is relatively monotonous, so users cannot identify the air supply status inside the refrigerator.

[0031] Based on the above situation, the embodiment of the present application proposes a light-emitting panel and a refrigerator, aiming to enable the user to intuitively understand the air supply status inside the refrigerator.

[0032] Various embodiments of the light-emitting panel of the present application are further described below in conjunction with the accompanying drawings.

[0033] like Figure 1 As shown, Figure 1 1 is a schematic diagram of the structure of a light-emitting panel 100 provided in one embodiment of the present application.

[0034] In one embodiment, the light-emitting panel 100 is used to be arranged in a refrigerator, wherein the light-emitting panel 100 is not limited to a first transparent substrate 111, a second transparent substrate 112 and a plurality of LED light sources 120. Specifically, the plurality of LED light sources 120 are located between the first transparent substrate 111 and the second transparent substrate 112, and the LED light source 120 is also connected to a conductive circuit 130, one end of the conductive circuit 130 is connected to the LED light source 120, and the other end is connected to a driving board.

[0035] Specifically, the driving board can drive the multiple LED light sources 120 to light up, turn off, or change in a preset pattern; wherein the driving board can drive the display state of the multiple LED light sources 120, thereby achieving a visual effect that can characterize the air supply state inside the refrigerator. Since the light-emitting panel 100 of the embodiment of the present application can display the internal air supply state of the refrigerator through the display state of the multiple LED light sources 120, the user can intuitively observe the air supply situation inside the refrigerator through the light-emitting panel 100, giving the user a more intuitive experience.

[0036] It should be noted that, regarding the installation position of the light-emitting panel 100, it can be installed inside the refrigerator, for example, the light-emitting panel 100 can be installed on at least one inner wall of the compartment of the refrigerator, or on at least one inner wall of the door panel of the refrigerator, or on other positions inside the refrigerator; in addition, the light-emitting panel 100 can also be installed outside the refrigerator, for example, the light-emitting panel 100 can be installed on at least one outer wall of the door panel of the refrigerator, or on other positions outside the refrigerator.

[0037] For different installation positions of the above-mentioned light emitting panel 100, the display scenes may be as follows:

[0038] Scenario 1: When the light-emitting panel 100 is installed inside the refrigerator, after opening the refrigerator door, the user can directly observe the pattern displayed by the LED light source 120 on the light-emitting panel 100 on the inner wall of the compartment or the inner wall of the door panel, so that the user can directly know the air supply situation inside the refrigerator, such as whether the refrigerator damper is in the open air supply state or the refrigerator damper is in the closed air supply stop state.

[0039] Scenario 2: When the light-emitting panel 100 is installed on the outside of the refrigerator, when the user approaches the refrigerator, he can directly observe the pattern displayed by the LED light source 120 on the light-emitting panel 100 on the outer wall of the door panel, so that the user can directly know the air supply conditions inside the refrigerator, such as whether the refrigerator damper is in the open air supply state or the refrigerator damper is in the closed air supply state.

[0040] It should be noted that the above-mentioned air supply state inside the refrigerator may refer to a state in which the refrigerator damper is open and air is supplied, or it may refer to a state in which the refrigerator damper is closed and air supply is stopped. The embodiment of the present application does not make any specific limitation on this.

[0041] In one embodiment, the first transparent substrate 111 and the second transparent substrate 112 need to be made of transparent materials to achieve a transparent effect, wherein the first transparent substrate 111 and the second transparent substrate 112 may be transparent glass products, which have the advantages of high transparency, chemical stability, heat resistance, corrosion resistance, etc.; or, the first transparent substrate 111 and the second transparent substrate 112 may also be transparent plastic products, such as polymethyl methacrylate, polycarbonate, etc., which have the advantages of lightness, easy processing, and low price; or, the first transparent substrate 111 and the second transparent substrate 112 may also be transparent ceramic products, such as aluminum oxide, zirconium oxide, etc., which have the characteristics of high hardness and high corrosion resistance; or, the first transparent substrate 111 and the second transparent substrate 112 may also be transparent crystal products, such as quartz crystal, calcium fluoride crystal, etc. In addition, the first transparent substrate 111 and the second transparent substrate 112 may also be made of other materials, which is not specifically limited in the embodiment of the present application.

[0042] In one embodiment, the above-mentioned LED light source 120 refers to a light emitting diode light source, which is a solid-state semiconductor device that can directly convert electrical energy into light energy and has the advantages of small size, long life, high efficiency, etc. The embodiment of the present application can use the LED light source 120 for pattern display, wherein the brightness of the LED light source 120 can be controlled by adjusting the current, so when it is necessary to display patterns of different levels, it can be achieved by adjusting the brightness of the LED.

[0043] Among them, the embodiment of the present application can add a light detection sensor for detecting the current ambient brightness to the refrigerator, so that the LED light source 120 can adjust its own brightness according to the ambient brightness information detected by the light detection sensor. For example, when the light detection sensor detects that the current environment is brighter, in order to enable the user to clearly see the pattern displayed by the LED light source 120, the embodiment of the present application can respond to increase the brightness of the LED light source 120; or, when the light detection sensor detects that the current environment is darker, in order not to cause a glare effect to the user, the embodiment of the present application can respond to reduce the brightness of the LED light source 120.

[0044] In one embodiment, in order to make the overall transparency of the light-emitting panel 100 better, the conductive line 130 can be a conductive line made of a transparent material, which can meet the requirements of transmitting light and transmitting current. For example, the conductive line 130 can be made of transparent materials such as transparent plastic or glass fiber, which has good conductivity and can transmit light.

[0045] In one embodiment, the position of the driving board is arranged at the edge of the light emitting panel 100, and then connected to the main control board of the refrigerator through a power supply cable and a communication cable. In addition, the driving board can also be arranged away from the light emitting panel 100, and the embodiment of the present application does not specifically limit the installation position of the driving board.

[0046] In one embodiment, the light emitting panel 100 of the embodiment of the present application can be set on the inner wall of the compartment of the refrigerator; the driving board can select and drive multiple LED light sources 120 to emit light or change in a preset pattern to form a visual effect for representing that the refrigerator air duct is in an air supply state. Alternatively, the driving board can also drive the LED light source 120 to turn off to form a visual effect for representing that the refrigerator air duct is in a non-air supply state.

[0047] It should be noted that the above-mentioned preset style changes can be a flowing style, that is, multiple LED light sources 120 emit light in sequence; it can also be a flashing style, that is, multiple LED light sources 120 flash continuously; it can also be other styles, and the embodiments of the present application do not make specific limitations on this.

[0048] For example, when the plurality of LED light sources 120 emit light in a flowing pattern or a flashing pattern, it may indicate that the refrigerator damper is open and supplying air; when the plurality of LED light sources 120 are off, it may indicate that the refrigerator damper is closed and stops supplying air.

[0049] It should be noted that the embodiments of the present application may use different preset styles to represent different air supply speeds, or different display effects under the same preset style may be used to represent different air supply speeds. For example, when multiple LED light sources 120 emit light at a high-frequency speed in a flowing style, it can represent that the refrigerator damper is open and supplies air at a high speed; when multiple LED light sources 120 emit light at a medium-frequency speed in a flowing style, it can represent that the refrigerator damper is open and supplies air at a medium speed; when multiple LED light sources 120 emit light at a low-frequency speed in a flowing style, it can represent that the refrigerator damper is open and supplies air at a low speed.

[0050] In addition, in one embodiment, the embodiment of the present application can also control the luminous color of the LED light source 120 in the arrangement combination 200 through the driving board, so as to characterize the air supply speed through the luminous color. For example, if the luminous color of the LED light source 120 in the arrangement combination 200 is red, it can be characterized that the refrigerator damper is open and high-speed air supply is performed; if the luminous color of the LED light source 120 in the arrangement combination 200 is blue, it can be characterized that the refrigerator damper is open and medium-speed air supply is performed; if the luminous color of the LED light source 120 in the arrangement combination 200 is green, it can be characterized that the refrigerator damper is open and low-speed air supply is performed.

[0051] Since the embodiment of the present application adds the above-mentioned light-emitting panel 100 to the inner wall of the refrigerator compartment, and the light-emitting panel 100 can display the internal air supply status of the refrigerator through the display status of multiple LED light sources 120, the user can intuitively observe the air supply situation inside the refrigerator through the light-emitting panel 100, giving the user a more intuitive experience.

[0052] It should be noted that, in the embodiment of the present application, the light emitting panel 100 can be arranged at the position of the inner wall of the compartment corresponding to the refrigerator air duct, that is, the inner wall of the compartment is provided with the light emitting panel 100, and the outer wall of the compartment is the air duct.

[0053] In one embodiment, if Figure 2 As shown, Figure 2This is a visual effect diagram of a light-emitting panel 100 provided by an embodiment of the present application; a plurality of LED light sources 120 are arranged to form at least one group of permutations and combinations 200, wherein the plurality of LED light sources 120 in each group of permutations and combinations 200 are arranged in a horizontal or vertical arrangement; the driving board can drive the plurality of LED light sources 120 in the permutations and combinations 200 to emit light in sequence, so as to form a visual effect of running water lights for representing that the refrigerator air duct is in an air supply state. Figure 2 The LED light sources 120 with solid shadows in the figure are emitting LED light sources 120 , and the LED light sources 120 with hollow shadows are extinguished LED light sources 120 .

[0054] In one embodiment, there are multiple light-emitting panels 100, and one light-emitting panel 100 is correspondingly arranged in one air supply area; for each air supply area, the display status of multiple LED light sources 120 in the light-emitting panel 100 is used to characterize the air supply status of the air supply area.

[0055] For example, in an embodiment of the present application, a light-emitting panel 100 can be set in the refrigerator's refrigerator compartment, and another light-emitting panel 100 can be set in the refrigerator's freezer compartment, wherein the light-emitting panel 100 in the refrigerator compartment is used to characterize the air supply state of the refrigerator compartment, and the light-emitting panel 100 in the freezer compartment is used to characterize the air supply state of the freezer compartment.

[0056] In one embodiment, if Figure 1 As shown, the light emitting panel 100 of the embodiment of the present application further includes but is not limited to a light-transmitting film 140 . The light-transmitting film 140 is disposed between the first transparent substrate 111 and the second transparent substrate 112 , and the LED light sources 120 are distributed on the light-transmitting film 140 .

[0057] The embodiment of the present application can adopt a solution in which a light-transmitting film 140 carries the LED light source 120, which can reduce the thickness of the light-emitting panel 100. The light-transmitting film 140 can be a flexible transparent material. The light-transmitting film 140 serves as a carrying layer to form a conductive circuit 130 on the first surface. For example, the conductive circuit 130 is etched on the coated light-transmitting film 140 by laser etching or the like, and then the LED light source 120 is connected to the flexible transparent film on which the conductive circuit 130 has been etched through an ITO (indium tin oxide, Indium-Tin-Oxide) conductive electrode or conductive ink to form an LED flexible display film. The LED flexible display film is connected to the driving board to form the light-emitting panel 100 of the present application.

[0058] In one embodiment, the light emitting panel 100 further includes a pattern component, which is disposed on the surface of the first transparent substrate 111, the second transparent substrate 112 or the transparent film 140, and includes a transparent area and an opaque area, which cooperate with each other to form a pattern.

[0059] For example, the front of the pattern component is the appearance surface. Different patterns can be achieved by cooperating with the light-transmitting area and the opaque area, and the driving board can be further used to control the LED light source 120 to change according to a certain rule, so that the pattern on the pattern component can form dynamic effects such as gradient, flashing, and flowing jump, thereby improving the aesthetics of the refrigerator.

[0060] In one embodiment, the light-transmitting area and the light-impermeable area of ​​the pattern component are set according to the style of the actual pattern, wherein the light-transmitting area can be designed as a wind direction flow pattern, and the light-impermeable area can be designed as other patterns. In short, the light-transmitting area and the light-impermeable area of ​​the pattern component are set according to the actual pattern, and the light-transmitting area can be set with multiple areas of different transparency, so as to form a pattern with better aesthetics.

[0061] In one embodiment, the light-transmitting film 140 is a PVB film or an EVA film.

EVA film is also called ethylene-vinyl acetate copolymer film, which is a thermoplastic elastomer material and is widely used in various fields.

[0062] In one embodiment, the embodiment of the present application can use a special lamination process to encapsulate a single LED light source 120 between two pieces of tempered glass to make a flat luminous glass product with a safe sandwich structure. The LED luminous glass is prepared by an etching process, and the refrigerator air duct pattern can be dynamically displayed by quickly switching the switch. In addition, the pattern of wind direction flow can be designed to display the air supply area in different zones. Using LED lights of different colors to arrange a colorful effect, combined with various colored glass and craft glass, more changing effects of the air duct can be created.
