It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0037] With the development of Internet of Things technology, smart home devices are gradually popular. In the aspect of refrigerators, consumers not only pursue the basic functions of freezing and refrigerating, but also hope that it can provide more intelligent, more personalized and more integrated services, such as "viewing online recipes, health diet management, smart shopping list, home entertainment", etc., which makes the refrigerator equipped with a display one of the market choices. At present, the display generally adopts a touch screen for interaction. When the refrigerator door is opened and closed, the cold air in the refrigerator will overflow, so that the surface temperature of the touch panel of the refrigerator door, especially the touch screen part, is lowered. At this time, if the external environment humidity is high and the air is warm, when the warm and humid air contacts the relatively cold touch panel surface, the water vapor in the air will condense into water droplets due to the temperature difference, affecting the use of the touch screen. After investigation, the refrigerator products on the market with anti-condensation function usually adopt special coating or use metal heating wire to reduce the generation of condensation, but when the environmental humidity is too high or the temperature difference is too large, local heating of the metal wire and the coating are not enough to completely avoid the condensation phenomenon.

[0038] Based on this, the utility model provides a kind of anti-condensation structure for display, refrigerator door and refrigerator, to achieve anti-condensation function by using carbon fiber resistance heating temperature rise effect.

[0039] Please see Figure 1 The anti-condensation structure for display provided by the utility model is arranged in display, wherein, display includes touch panel 1, screen 2 and support 3 which are sequentially stacked, touch panel 1 has transparent area 11 corresponding to screen 2 and non-transparent area 12 arranged around transparent area 11. Based on this, the anti-condensation structure for display includes:

[0040] Carbon fiber piece 4 is arranged on non-transparent area 12 of touch panel 1 and located at the side of screen 2, for heating to improve the temperature of touch panel 1 when current passes through;

[0041] Conductive assembly is arranged on support 3 and connected with carbon fiber piece 4, for delivering current to carbon fiber piece 4 when energized.

[0042] In practical application, when anti-condensation function is started, system energizes conductive assembly, current is delivered to carbon fiber piece 4 through conductive assembly;Carbon fiber piece 4 will heat due to Joule heating effect when current passes through, and its temperature gradually rises;At this time, heat generated by carbon fiber piece 4 is conducted to touch panel 1, and the temperature of touch panel 1 rises accordingly;With the temperature rise of touch panel 1, condensation phenomenon on the surface of touch panel 1 will gradually disappear.

[0043] It can be seen that the utility model utilizes carbon fiber resistance heating temperature rise effect, and conducts heat to touch panel 1 to achieve anti-condensation function.

[0044] Compared with the traditional anti-condensation design of built-in metal heating wire or special coating, the anti-condensation structure for the display has the advantages of fast response, fast temperature rise and high dew removal efficiency due to the carbon fiber Joule heat effect; the carbon fiber material is adopted, and the structure of the existing display is slightly changed, so that the structural complexity is reduced, and the heating area is wider, more uniform and more stable, and high efficiency and energy saving are achieved.

[0045] In further preferred embodiments of the utility model, as shown in Figure 1 、 Figure 2 The carbon fiber piece 4 adopts a frame structure, is attached to the non-transparent area 12 of the touch panel 1, and surrounds the periphery of the screen 2.

[0046] It should be understood that if the carbon fiber piece 4 adopts a frame structure, the carbon fiber piece 4 includes a left side plate, an upper side plate, a right side plate and a lower side plate which jointly form a square hole, wherein the left side plate, the upper side plate, the right side plate and the lower side plate can be integrally formed or spliced. This design is beneficial to increasing the overall area of the carbon fiber piece 4, so that the heating area is wider.

[0047] In other optional embodiments, the carbon fiber piece 4 adopts a strip structure, and the number of the carbon fiber piece 4 is four, and the four carbon fiber pieces 4 are all attached to the non-transparent area 12 of the touch panel 1 and located at the periphery of the screen 2.

[0048] In further preferred embodiments of the utility model, as shown in Figure 1 The conductive assembly includes two copper electrodes 5 which are arranged on the support 3 in an up-down interval, and the two copper electrodes 5 are connected with the upper and lower side edges of the carbon fiber piece 4.

[0049] In actual application, the two copper electrodes 5 are connected with the positive and negative poles of the power line. Thus, when the current loop in which the two copper electrodes 5 are located is turned on, the current can flow to the carbon fiber piece 4 through the two copper electrodes 5.

[0050] In other optional embodiments, the conductive assembly includes at least one pair of copper electrodes 5, and each pair of copper electrodes 5 includes two copper electrodes 5 which are connected with the positive and negative poles of the power line. One pair of copper electrodes 5 is arranged on the support 3 in a left-right interval and connected with the left and right side edges of the carbon fiber piece 4, and another pair of copper electrodes 5 is arranged on the support 3 in an up-down interval and connected with the upper and lower side edges of the carbon fiber piece 4.

[0051] In further preferred embodiments of the utility model, the carbon fiber piece 4 is made of carbon fiber reinforced thermoplastic resin matrix composite material.

[0052] It can be understood that the carbon fiber reinforced thermoplastic composite material is a new type of material with high strength, high rigidity, corrosion resistance and other advantages. Its main components are thermoplastic resin and carbon fiber. The thermoplastic resin has good plasticity, strong processability and other characteristics, and the thermoplastic resin includes but is not limited to polypropylene (PP), polyamide 6 (PA6), polyamide 66 (PA66), polyether ether ketone (PEEK), polyphenylene sulfide (PPS), and the carbon fiber has the characteristics of light weight, high strength, high rigidity, corrosion resistance and the like, and the carbon fiber layer can adopt but is not limited to a braided structure, a continuous wire bundle structure. It can be seen that the carbon fiber reinforced thermoplastic composite material has excellent performance.

[0053] In a further preferred embodiment of the utility model, the anti-condensation structure for display further includes a detection sensor arranged on the support 3, and a detection end of the detection sensor is connected with the non-transparent area 12 of the touch panel 1.

[0054] It should be noted that a controller is further arranged in the system, the controller is connected with the detection sensor, the controller receives data of the detection sensor, and the controller intelligently controls start and stop of the anti-condensation function according to the data of the detection sensor.

[0055] In actual application, the condensation phenomenon on the surface of the touch panel 1 can be reflected by the transmittance τ of light or the humidity of the surrounding environment, so the detection sensor can adopt a light sensor 6 or a humidity sensor. The light sensor 6 can detect the transmittance τ of light after the light passes through the touch panel 1, and the humidity sensor can detect the humidity of the environment where the touch panel 1 is located.

[0056] The utility model discloses through setting up light sensor 6 or humidity sensor and so on detection sensor real time monitoring, help controller knows the condensation condition on the surface of touch panel 1 in time, in order to automatic control anti-condensation function start and stop, ensure that the display touch function normally runs.

[0057] Please refer to Figure 1 The refrigerator door provided by the utility model includes a door body frame 7 and a display embedded in the door body frame 7, and the display has the anti-condensation structure for display as described above to realize the anti-condensation function.

[0058] In a preferred embodiment of the utility model, specifically, the refrigerator door mainly includes a door body frame 7 and a display, and a containing groove is formed in the front side of the door body frame 7, and the display is placed in the containing groove. The display includes a touch panel 1, a screen 2, a support 3, a carbon fiber piece 4, a conductive assembly and a light sensor 6.

[0059] The touch panel 1 has a transparent area 11 corresponding to the screen 2 and a non-transparent area 12 arranged around the transparent area 11. Thus, the screen 2 arranged behind the touch panel 1 can be exposed through the transparent area 11 of the touch panel 1. The touch panel 1 can be a glass panel, and a part of the glass panel can be provided with a black adhesive layer to form the non-transparent area 12, and the glass panel has impact resistance.

[0060] The screen 2 is tightly attached to the transparent area 11 of the touch panel 1; the carbon fiber piece 4 has a frame structure, that is, the carbon fiber piece 4 includes left, upper, right and lower side plates connected end to end, and the carbon fiber piece 4 is tightly attached to the non-transparent area 12 of the touch panel 1 and surrounds the screen 2; the conductive assembly includes two copper electrodes 5 fixed on the support 3 and connected to the upper and lower side edges of the carbon fiber piece 4; the light sensor 6 is fixed on the support 3, and the light sensing end of the light sensor 6 is tightly attached to the non-transparent area 12 of the touch panel 1.

[0061] It should be understood that the transmittance τ is detected by the light sensor 6, so that the transmittance change Δτ can be obtained. Specifically, when condensation appears on the touch panel 1, the path of the light through the condensation and the touch panel 1 changes, resulting in a decrease in transmittance, and the transmittance change Δτ can be obtained according to the data of the light sensor 6.

[0062] The anti-condensation function starting process is that the light sensor 6 detects the transmittance τ in real time, the controller automatically controls the anti-condensation function to be activated according to the transmittance change Δτ, and the system will power on the copper electrode 5; after the copper electrode 5 is powered on, the current flows to the carbon fiber piece 4 through the copper electrode 5, the carbon fiber piece 4 generates heat due to the Joule heating effect when the current passes through, and the temperature of the carbon fiber piece 4 gradually rises; at this time, the heat generated by the carbon fiber piece 4 is conducted to the touch panel 1, and the temperature of the touch panel 1 rises; as the temperature of the touch panel 1 rises, the condensation phenomenon on the surface of the touch panel 1 gradually disappears.

[0063] Compared with the conventional anti-condensation design of built-in metal heating wire or special coating, the structure complexity of the refrigerator door is reduced, and the heating area is wider, more uniform and more stable.

[0064] Please see Figure 3 The refrigerator provided by the utility model includes a cabinet, and further includes a plurality of refrigerator doors.

[0065] In a preferred embodiment of the utility model, specifically, the refrigerator includes a cabinet, and the cabinet has a refrigerating chamber and a freezing chamber arranged in an up-down manner. The refrigerator further includes four refrigerator doors, two of which correspond to the refrigerating chamber and will be referred to as refrigerator refrigerating chamber doors hereinafter, and the other two of which correspond to the freezing chamber and will be referred to as refrigerator freezing chamber doors hereinafter.

[0066] And, one of the refrigerator freezer compartment doors is provided with a display. Figure 1 As shown, the front side of the door body frame 7 is provided with a receiving groove, and the display is placed in the receiving groove. The display comprises a touch panel 1, a screen 2, a support 3, a carbon fiber piece 4, a conductive assembly and a light sensor 6. The touch panel 1 has a transparent area 11 corresponding to the screen 2 and a non-transparent area 12 arranged around the transparent area 11. The screen 2 is tightly attached to the transparent area 11 of the touch panel 1; the carbon fiber piece 4 has a frame structure, i.e. the carbon fiber piece 4 comprises a left side plate, an upper side plate, a right side plate and a lower side plate connected end to end, and the carbon fiber piece 4 is tightly attached to the non-transparent area 12 of the touch panel 1 and surrounds the screen 2; the conductive assembly comprises two copper electrodes 5 fixed on the support 3 and connected to the upper and lower side edges of the carbon fiber piece 4; and the light sensor 6 is fixed on the support 3, and the light sensing end of the light sensor 6 is tightly attached to the non-transparent area 12 of the touch panel 1.

[0067] In actual application, when the refrigerator freezer compartment door is opened to take out the food in the freezer compartment, the cold air in the freezer compartment escapes from the drawer and contacts the refrigerator freezer compartment door, so that the temperature of the touch panel 1 on the surface of the refrigerator freezer compartment door with the large screen 2 display is reduced. When the high-humidity and warm air in the external environment of the refrigerator contacts the relatively cold touch panel 1, the water vapor in the air will condense into water droplets, which affects the use of the touch screen. When the condensation occurs on the touch panel 1, the light transmits through the condensation and the touch panel 1, and the transmittance τ of the light will change. Figure 4 As shown, the light sensor 6 detects the transmittance τ, and the controller automatically controls the start and stop of the anti-condensation function according to the change Δτ of the transmittance. When the change Δτ of the transmittance is large, the copper electrodes 5 are powered on. Specifically, the controller controls the direct current power supply to load direct current to the copper electrodes 5 located on the upper and lower sides of the carbon fiber piece 4, the carbon fiber piece 4 accumulates heat when current passes through and transmits the heat to the touch panel 1, so that the touch panel 1 maintains a high temperature, thereby evaporating the condensation on the surface of the touch panel 1 and effectively alleviating the condensation phenomenon caused by the contact of the water vapor in the air with the relatively cold touch panel 1. Conversely, when the change Δτ of the transmittance is small, the copper electrodes 5 are not powered on.

[0068] It can be seen that the preferred embodiment of the present application constructs an anti-condensation self-resistance heating system, detects the transmittance τ through the light sensor 6, triggers the copper electrodes 5 to be powered on according to the change Δτ of the transmittance, and makes the carbon fiber piece 4 generate heat; the heat is transmitted to the touch panel 1 through heat conduction, so as to increase the temperature of the touch panel 1 and realize the anti-condensation function. This process not only can effectively prevent condensation, but also can maintain the transparency and optical performance of the touch panel 1, and ensure the normal operation of the touch function of the display.

[0069] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
