Description

Technical Field

[0001] The present application relates to the field of household appliance technology, for example, to an energy-saving heating component and refrigeration equipment based on graphene technology. Background Art

[0002] In refrigeration equipment, when wet air flows through the evaporator, the temperature of the evaporator is lower than the air temperature, and water is condensed on the surface of the evaporator, including the surface of the fins and evaporation tubes. When the air flows through the fins, it is first condensed at the air inlet of the evaporator and slowly enters the inside of the evaporator. The water in the air becomes less and less, and finally after passing through the fin evaporator, the air becomes dry air.

[0003] In a frost-free refrigeration system, the water in the air gradually disappears after passing through the finned evaporator, and the air becomes nearly dry. A large amount of water condenses on the evaporator, especially at the air inlet of the evaporator. There is less frost near the outlet. If the return air outlet of the refrigerator is designed next to the evaporator, there will be more frost on the evaporator, indicating that more water vapor is brought from the refrigerator. Under severe use conditions, there will be less frost on the upper part of the evaporator, while the lower part will be completely blocked by frost.

[0004] After a long period of refrigeration, the frost on the evaporator will increase, blocking the air inlet of the evaporator, resulting in a blocked air circulation channel. The temperature of the refrigerator drops slowly, similar to no refrigeration. At this time, the evaporator should be defrosted, otherwise the food will spoil after the temperature rises. Forced defrosting actually adds extra heat to melt the frost on the evaporator and turn it into water to flow out of the evaporator. The more frost there is, the more heat is needed.

[0005] At present, when defrosting, a heating device is often used to heat the entire evaporator directly near the evaporator. The heating device is mostly controlled by a power. When used to defrost the refrigerator / freezer, the entire process is one power, which can easily lead to uneven defrosting, that is, the frost in some areas has already melted while the frost in other areas has not yet been removed. This will also lead to excessive heating, energy waste, and safety hazards caused by excessive temperature in local areas.

[0006] Therefore, it can be seen that how to maintain defrosting efficiency while avoiding excessive heating and energy waste has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0008] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0009] The embodiments of the present disclosure provide an energy-saving heating component and refrigeration equipment based on graphene technology to solve the problems of uneven defrosting, excessive heating, energy waste, and safety hazards caused by excessive temperature in local areas.

[0010] In some embodiments, the energy-saving heating component based on graphene technology includes: a heating plate, an electrode strip and a heating film. The heating plate is divided into multiple heating zones; the electrode strip includes a first electrode strip and a second electrode strip, which are respectively arranged on the left and right sides of the surface of the heating plate; there are multiple heating films, and the multiple heating films have different heating powers, and the multiple heating films are sequentially attached to different heating zones on the heating plate, and the two ends of the heating films are respectively adaptably connected to the electrode strips.

[0011] Optionally, a first connection contact is provided on the electrode strip, and second connection contacts are provided at both ends of the heating film, which can be adaptively connected to the first connection contact.

[0012] Optionally, the electrode strips are embedded in the heating plate.

[0013] Optionally, boundary areas are provided between the multiple heating areas.

[0014] Optionally, the plurality of heating films have different sizes.

[0015] Optionally, the heating plate is any one of the following materials: glass fiber board, epoxy resin board, mica board, polypropylene board, polyethylene board, polyimide board.

[0016] Optionally, the heating film is made of graphene.

[0018] Optionally, the heating plate is made of rigid material.

[0019] In some embodiments, the refrigeration device includes: an energy-saving heating component based on graphene technology according to any of the above embodiments.

[0020] The energy-saving heating components and refrigeration equipment based on graphene technology provided by the embodiments of the present disclosure can achieve the following technical effects:

[0021] By dividing the heating plate into multiple heating areas and attaching multiple heating films with different heating power in different heating zones of the heating plate, the overall heating plate has multiple heating areas with different heating power, which is convenient for providing different heat to different areas on the evaporator and the fins. When the degree of frost in different areas of the evaporator and the fins is different, defrosting can be completed synchronously at various positions to avoid the problem of overheating of some areas when defrosting is completed in part and in the rest of the parts. While maintaining a good defrosting effect, the defrosting efficiency is improved, the defrosting time is shortened, and more energy is saved. At the same time, the heating film can be directly adapted and connected to the electrode strips on the heating plate, which improves the convenience of overall assembly and is more flexible to use.

[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0039] Combination Figure 1-4 As shown, the embodiment of the present disclosure provides an energy-saving heating component based on graphene technology, including: a heating plate 100, an electrode strip 200 and a heating film 300. The heating plate 100 is divided into a plurality of heating zones 101; the electrode strip 200 includes a first electrode strip 201 and a second electrode strip 202, which are respectively arranged on the left and right sides of the surface of the heating plate 100; a plurality of heating films 300 are provided, and the plurality of heating films 300 have different heating powers, and the plurality of heating films 300 are sequentially attached to different heating zones 101 on the heating plate 100, and the two ends thereof are respectively adaptably connected to the electrode strip 200.

[0040] By adopting the energy-saving heating component based on graphene technology provided by the embodiment of the present disclosure, a plurality of heating zones 101 are divided on the heating plate 100, and a plurality of heating films 300 with different heating powers are attached to different heating zones 101 of the heating plate 100, so that the overall heating plate 100 has a plurality of heating zones 101 with different heating powers, so as to provide different heat to different areas on the evaporator and the fins. When the degree of frost in different areas of the evaporator and the fins is different, defrosting can be completed synchronously at various positions to avoid the problem of overheating of some areas caused by the situation that defrosting is completed in part and defrosting in other parts is not completed. While maintaining a good defrosting effect, the defrosting efficiency is improved, the defrosting time is shortened, and energy saving is increased. At the same time, the heating film 300 can be directly adapted and connected to the electrode strips 200 on the heating plate 100, so as to improve the convenience of overall assembly and make it more flexible to use.

[0041] It is understandable that the heating area 101 can be freely set by the user according to actual needs. In this way, it is convenient for the user to make reasonable settings according to actual use needs, improve the flexibility and convenience of overall use, and better the heating effect of the evaporator and the fins.

[0042] Optionally, the heating film 300 is attached to the heating plate 100 by a heat-resistant adhesive. In this way, the stability of the connection between the heating film 300 and the heating plate 100 can be improved, so that the heating film 300 can be better attached to the heating plate 100.

[0043] Optionally, the heating film 300 is fixedly clamped on the heating plate 100 by a clamping plate 400. In this way, the heating film 300 is clamped and fixed by the clamping plate 400, which is easier to disassemble than the method of fixing with adhesive, and is more convenient during installation. In addition, if part of the heating film 300 is damaged, the damaged heating film 300 can be directly disassembled and replaced, thereby improving the overall convenience and flexibility of use.

[0044] Optionally, the clamping plate 400 is a heat-resistant strip plate, which is detachable from the heating plate 100, and the edge of the heating film 300 can be clamped between the heating plate 100 and the clamping plate 400. In this way, the heating film 300 is clamped and fixed by the strip-shaped clamping plate 400, and the overall flatness can be maintained.

[0045] Optionally, the clamping plate 400 and the heating plate 100 are detachably fixed by screws, so that the clamping plate 400 can be easily removed and fixed relative to the heating plate 100 .

[0046] Optionally, the electrode strip 200 is provided with a first connection contact 203, and the two ends of the heating film 300 are provided with second connection contacts 301, which can be adapted to be connected with the first connection contacts 203. In this way, when the heating film 300 is covered and installed on the heating plate 100, the second connection contacts 301 at both ends of the heating film 300 can be adapted to be connected with the first connection contacts 203 on the electrode strip 200, thereby improving the convenience of electrifying the heating film 300, making it easier to use the heating film 300 in combination in different heating zones 101 on the heating plate 100, and improving the overall flexibility of use.

[0047] Optionally, the first connection contact 203 and the second connection contact 301 are connected by soldering. In this way, the connection method of soldering can maintain the stability of the connection between the first connection contact 203 and the second connection contact 301, and keep the electrical connection between the two more stable, avoiding problems such as leakage or increased resistance caused by poor contact.

[0048] Optionally, the first connection contact 203 is a concave structure, and the second connection contact 301 is a convex structure, wherein the convex structure can be adapted to be clamped in the concave structure. In this way, the connection is made by using a concave and convex structure that cooperates with each other, which can further improve the stability of the connection, and there is no need to use soldering to reinforce the connection, which facilitates the disassembly and installation between the first connection contact 203 and the second connection contact 301, and makes the replacement and maintenance of the overall heating film 300 more convenient in the later stage.

[0049] Optionally, the clamping plate 400 covers the edges of the electrode strip 200 and the heating film 300. In this way, by clamping and fixing the edge position of the heating film 300, the stability of the entire heating film 300 can be maintained without affecting the heating and heat dissipation of the heating film 300. At the same time, the clamping plate 400 also covers the electrode strip 200, which can prevent the electrode strip 200 from water ingress and leakage, and can improve the stability of the connection between the first contact point and the second contact point.

[0050] Optionally, the clamping plate 400 is made of a high temperature resistant insulating material. In this way, the high temperature resistant property of the clamping plate 400 is used to maintain the stability of the clamping plate 400 under high temperature conditions, and the insulating property of the clamping plate 400 is used to better maintain the insulation effect at the electrode strip 200, thereby reducing the risk of leakage.

[0051] Optionally, the electrode strip 200 is embedded in the heating plate 100. In this way, the electrode strip 200 is embedded in the heating plate 100 to prevent the electrode strip 200 from protruding, improve the stability of the electrode strip 200 relative to the heating plate 100, keep the heating plate 100 flat, and have a good protective effect on the electrode strip 200, avoid damage to the electrode strip 200, and improve the service life of the electrode strip 200.

[0052] Optionally, the electrode strips 200 are covered with an insulating coating, so that leakage of the electrode strips 200 can be effectively avoided, thereby improving the safety of use.

[0053] Optionally, the electrode strip 200 is also covered with a temperature insulation layer. In this way, the electrode strip 200 is protected by the temperature insulation layer covering the electrode strip 200 to prevent the high temperature from affecting the safety of the electrode strip 200 when the heating film 300 is heated, and to prevent the high temperature from increasing the resistance of the electrode strip 200, thereby reducing energy loss.

[0054] Optionally, a boundary area 102 is provided between the plurality of heating areas 101. Thus, the boundary area 102 is used to demarcate two adjacent heating areas 101, thereby avoiding the large difference in heating power between the heating films 300 installed in the two heating areas 101 and causing mutual influence, thereby improving the working stability of each heating film 300.

[0055] The width of the boundary area 102 is less than or equal to 2 cm, and preferably, the width of the boundary area 102 is 1 cm. Thus, by setting the width of the boundary area 102 within 2 cm, the space occupancy is more reasonable, and it can also prevent the heating films 300 in two adjacent heating areas 101 from directly contacting each other and affecting their normal use.

[0056] Optionally, the plurality of heating films 300 have different sizes. In this way, the heating films 300 can be selected and installed according to the sizes corresponding to different positions on the evaporator and the fins, so that the size of the heating film 300 can better meet the heating conditions required at the corresponding position, and can better provide different heating for different positions, thereby maintaining a good heating effect on the evaporator and the fins, making it easier for frost at different positions on the evaporator and the fins to be defrosted at the same time, thereby improving the overall defrosting effect and speeding up the defrosting time.

[0057] Optionally, the heating film 300 is rectangular, and its second connection contacts 301 are arranged on two opposite sides of the width of the heating film 300, and the multiple heating films 300 of different sizes have the same width and different heights. In this way, the multiple heating films 300 are kept to have the same width, so that the arrangement on the heating plate 100 is more regular, and it can be more convenient to adapt and connect with the electrode strips 200 arranged in a straight line.

[0058] It can be understood that the width of the heating film 300 refers to the distance between the sides parallel to the electrode strips 200 .

[0059] Optionally, the heating plate 100 is any one of the following materials: glass fiber board, epoxy resin board, mica board, polypropylene board, polyethylene board, polyimide board. In this way, the heating plate 100, as the base of the heating film 300, can make the radiation performance of graphene better play, especially the transparent glass fiber board, epoxy board, and mica board will also have certain radiation energy after heating, which can further improve the heating effect.

[0060] Optionally, the heating plate 100 is further provided with a fixing hole 103. Thus, the fixing hole 103 can facilitate the fixing connection between the heating plate 100 and its installation position, and can also be used to connect the multiple heating plates 100 to each other when multiple heating plates 100 are used, thereby improving the overall convenience and flexibility of use.

[0061] Optionally, the heating film 300 is made of graphene. In this way, the heating film 300 made of graphene can not only heat and cool quickly, but also has a radiation enhancement effect, generating infrared light with a radiation rate of more than 0.9. When the heating plate 100 is applied to the evaporator defrosting, compared with the traditional heating device, it not only has a faster heating speed and more uniform heating, but also has a radiation enhancement effect, which is more conducive to defrosting and further shortens the defrosting time.

[0062] It can be understood that the heating film 300 can also be made of conductive ink material, or other energy-saving heating films 300. The specific structure of the graphene conductive film and the conductive ink film is a conventional technology in the field and will not be elaborated here.

[0063] Optionally, the electrode strip 200 is provided with a wiring hole 204. In this way, it is convenient to use the wiring hole 204 to connect the electrode strip 200 to a power source, and when multiple heating plates 100 are used in combination, multiple wiring holes 204 can be connected by wires, thereby improving the simplicity of the overall power connection structure and making the overall use more convenient.

[0064] Optionally, the insulating coating on the electrode strip 200 does not cover the inner wall of the wiring hole 204. In this way, the insulation of the electrode strip 200 as a whole can be maintained, while the wiring hole 204 can be normally conductive, so that multiple wiring holes 204 can be electrically connected.

[0065] Optionally, the heating plate 100 is made of a rigid material, so that the safety can be improved, the heating plate 100 has a certain hardness when used, and is not punctured, so as to ensure the safety of application and prevent the heating plate 100 from being punctured and causing problems such as short circuit, leakage, and fire.

[0067] By adopting the refrigeration equipment provided by the embodiment of the present disclosure, an energy-saving heating component based on graphene technology is installed on the refrigeration equipment to better defrost the evaporator and fins of the refrigeration equipment, a plurality of heating zones 101 are divided on the heating plate 100, and a plurality of heating films 300 with different heating powers are attached to different heating zones 101 of the heating plate 100, so that the overall heating plate 100 has a plurality of heating zones 101 with different heating powers, which is convenient for providing different heat to different areas on the evaporator and the fins. When the degree of frost in different areas of the evaporator and the fins is different, defrosting can be completed synchronously at each position to avoid the problem of overheating of some areas caused by the situation that defrosting is completed partially and defrosting is not completed in other parts. While maintaining a good defrosting effect, the defrosting efficiency is improved, the defrosting time is shortened, and energy saving is increased.
