Description
Technical Field
[0001] This utility model relates to the field of heating equipment technology, and more specifically, to a modular transparent heater that combines efficient convection heating with convenient maintenance. Background Technology
[0002] With the increasing aesthetic demands of modern homes and offices, heaters using transparent heating glass have become widely popular due to their transparency and aesthetic appeal. These heaters typically consist of one or more pieces of transparent heating glass and a frame for fixing and supporting the glass.
[0003] In existing technologies, such as the transparent glass heater disclosed in Chinese utility model patent CN222799117U, the frame is typically integrally fixedly connected to the heating glass to ensure structural stability and sealing. However, this integrated fixed structure has a significant drawback: the transparent heating glass, as the core component of the heater, is also a relatively fragile part, and may crack or become functionally damaged during long-term use, transportation, or accidental impacts. Once the heating glass is damaged, because it is firmly integrated with the frame, users cannot easily replace it themselves, and the entire device often has to be scrapped. This not only causes economic losses for users but also wastes resources, with extremely high repair costs, sometimes exceeding the cost of purchasing a new unit.
[0004] Therefore, how to provide a transparent heater that can be easily and cost-effectively replaced when the core heating component is damaged, while ensuring efficient heat convection, has become a technical problem that urgently needs to be solved in this field. Utility Model Content
[0005] The purpose of this invention is to provide a modular transparent heater to solve the technical problems of difficult maintenance and high cost caused by the integrated structure of existing transparent heaters.
[0006] This utility model provides a modular transparent heater, including a transparent heating element and a frame assembly for accommodating and supporting the transparent heating element. The transparent heating element consists of at least two parallel and spaced heating glass pieces, forming an internal, through-hole between the two heating glass pieces. The frame assembly includes multiple frame strips and multiple corner connectors for connecting the frame strips. The frame strips and corner connectors are detachably connected by fasteners, thereby forming a decomposable frame. The transparent heating element is detachably installed within the frame formed by the frame strips and corner connectors. Furthermore, the lower part of the frame assembly is provided with an air inlet communicating with the lower part of the cavity, and the upper part of the frame assembly is provided with an air outlet communicating with the upper part of the cavity, thereby forming an air convection channel.
[0007] It is evident that by creatively combining the efficient "double-glass convection structure" with the "modular detachable frame," when the core double-glass heating element is accidentally damaged, users can easily and independently replace the component by simply disassembling the frame by removing the fasteners, without having to scrap the entire unit. This greatly reduces maintenance costs and extends the product's lifespan. At the same time, this structure cleverly utilizes the "chimney effect" principle, enabling continuous and quiet natural air circulation in the room without the need for a fan. This allows heat to be delivered to the entire room more quickly and evenly, significantly improving the efficiency of whole-room heating and the comfort of heating.
[0008] Optionally, the inner side of the frame strip is provided with a slot for engaging the edge of the transparent heating element.
[0009] As can be seen, by setting a slot on the inside of the frame strip, a stable and reliable mounting base can be provided for the transparent heating component, ensuring that it is stable and does not wobble within the frame, thereby improving the structural stability and safety of the product.
[0010] Optionally, the card slot is a T-shaped card slot.
[0011] As can be seen, the T-shaped slot structure can limit and support the edge of the transparent heating element from multiple directions, and has a stronger fixing effect than ordinary slots. It can effectively prevent the heating element from accidentally shaking or falling out during transportation or use, and further enhance the reliability of the structure.
[0012] Optionally, each piece of the heating glass includes: a substrate layer; a conductive layer disposed on the substrate layer; an electrode disposed on the conductive layer for conducting electricity thereon; and an encapsulation layer covering the conductive layer and the electrode; wherein a non-conductive insulating region is formed between the edge of the conductive layer and the edge of the substrate layer.
[0013] It is evident that this multi-layered transparent structure design, combined with the setting of edge insulation areas, can achieve a transparent and aesthetically pleasing overall machine (with a light transmittance of over 80%), while physically isolating the path of current conduction to the metal frame. This fundamentally solves the leakage safety hazard of transparent heating elements, achieving a high degree of unity between aesthetics and safety.
[0014] Optionally, the width of the insulation zone is 5 mm to 15 mm.
[0015] It is evident that setting the width of the insulation zone within this range achieves the best balance between ensuring absolutely reliable insulation performance and maximizing the effective heating area. This ensures sufficient safety distance while avoiding the impact on the overall heating effect and visual aesthetics due to an excessively wide insulation zone.
[0016] Optionally, it also includes a smart controller that is electrically connected to the transparent heating element.
[0017] As can be seen, by configuring an intelligent controller, users can precisely adjust the power and temperature according to their actual needs, achieving a personalized and energy-saving heating experience; at the same time, its built-in overheat protection function greatly improves the safety of the product, effectively preventing the risk of burns or fires caused by abnormally high temperatures.
[0018] Optionally, the corner connectors and / or the frame strips are provided with screw holes that mate with fasteners, the fasteners being screws.
[0019] It is evident that using screws as fasteners is a mature, reliable, and cost-effective solution for achieving detachable connections. Users can easily disassemble and assemble the frame using only standard tools, providing a convenient operational basis for modular maintenance.
[0020] Optionally, the border strip and corner connectors are made of aluminum alloy.
[0021] It is evident that using aluminum alloy for the frame material can balance lightweight, high strength, and good heat dissipation, ensuring the stability and durability of the frame structure, facilitating user movement, and also assisting the entire heater in heat dissipation, thus improving the overall performance of the product.
[0022] Optionally, it also includes a base bracket located at the bottom of the frame assembly, on which casters are mounted.
[0023] As can be seen, by installing casters at the bottom, the ease of movement of the heater is greatly enhanced. Users can move it from the living room to the bedroom without any effort, meeting the heating needs of different spaces and at different times, and greatly improving the product's applicability and flexibility.
[0024] Optionally, the movable wheel is equipped with a braking device. Other features and advantages of the present invention will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings.
[0025] It is evident that adding a braking device to the casters can lock the heater after it has been moved to a designated position, preventing it from slipping accidentally. This is especially important in environments with uneven ground or where there are children or pets, effectively ensuring the stability and safety of the equipment when it is parked.

[0034] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0035] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.
[0036] Please see Figure 1 and Figure 2 This utility model provides a modular transparent heater. It combines a highly efficient convection heating structure with a unique modular and detachable structure, facilitating user replacement and maintenance of the core heating component. The overall structure of the heater mainly includes a large-area transparent heating element 1, a frame assembly 2 for housing and fixing the transparent heating element 1, an intelligent controller 4 mounted on the frame assembly 2, and a base assembly 5 supporting the entire device.
[0037] In this embodiment, the frame assembly 2 is the core component that enables the modularity and ease of maintenance of this invention. Unlike traditional heaters that use an integrated welded or glued frame, the frame assembly 2 in this embodiment is completely disassembled and reassembled. Figure 2 As shown, it is composed of multiple independent parts, mainly including: multiple border strips and multiple corner connectors 3. In this embodiment, the border strips specifically include an upper border strip 21, a lower border strip 22, a left border strip 23, and a right border strip 24, which together form the four sides of a rectangular frame.
[0038] Each frame strip is interconnected via corner connectors 3 at both ends and secured with several fasteners. To achieve this locking connection, screw holes are provided at corresponding positions on the corner connectors 3 and / or the frame strips, and the fasteners are screws (e.g., M4 screws) that engage with the threads of these screw holes. This "frame strip + corner connector + fastener" structure allows the entire frame to be easily disassembled into individual parts by loosening the screws. Preferably, both the frame strips and corner connectors 3 are made of lightweight, high-strength aluminum alloy with good heat dissipation properties through extrusion molding or die casting. EPDM rubber strips can also be embedded at the joints between the frame strips and corner connectors to improve sealing. This allows the entire unit to achieve an IPX4 waterproof rating, effectively preventing water splashes from any direction and ensuring safe use in humid environments such as bathrooms.
[0039] On the inner side of each frame strip, a slot is provided to accommodate the edge of the heated glass. Preferably, the slot is a T-shaped slot, whose T-shaped structure can limit the edge of the heated glass from three directions, preventing it from wobbling back and forth and providing stable vertical support, resulting in a reliable structure.
[0040] The transparent heating element 1 is the core component for achieving the heating function, and its installation and disassembly are greatly simplified due to the aforementioned modular frame design. To further enhance the overall heating effect of the room, the transparent heating element 1 of this invention consists of at least two parallel, spaced-apart heating glass pieces, forming an internal, through-hole between the two pieces. Preferably, the width of this cavity can be set to 5-30mm to balance convection efficiency and structural stability.
[0041] In conjunction with this structure, the lower part of the frame assembly 2 (e.g., on the lower frame strip 22) is provided with an air inlet for introducing external cold air, and the upper part (e.g., on the upper frame strip 21) is provided with an air outlet for discharging hot air. Both the air inlet and the air outlet can be in the form of a grille.
[0042] Therefore, when the two heated glass panes are energized, they heat the air inside the cavity between them. The hot air, due to its lower density, rises naturally and flows out from the upper vent; simultaneously, cold air from outside is passively drawn into the cavity through the lower inlet due to negative pressure, creating a continuous "chimney effect." This design cleverly utilizes the principle of thermal convection to create natural air circulation within the room, distributing heat more quickly and evenly throughout the room, significantly improving the efficiency and comfort of overall room heating, while maintaining the quiet operation of the equipment.
[0043] During assembly, first insert the lower edges of the two heating glass pieces constituting the transparent heating component 1 into the corresponding slots of the lower frame strip 22. Then, assemble the left, right, and upper frame strips and corner connectors 3 in sequence and tighten them with fasteners to securely fix the transparent heating component 1 within the frame. Conversely, when it is necessary to replace the transparent heating component 1, simply reverse the process, loosen the fasteners, disassemble the frame assembly 2, and the old transparent heating component 1 can be easily removed and replaced with the new one.
[0044] Please see Figure 3 To ensure the functionality and safety of the heater, each piece of heating glass constituting the transparent heating element 1 is specially designed. Its overall transparency is achieved because each layer of the main body of the element is made of a highly transparent material. Its heating principle is based on the Joule heating effect, which is well-known in the art. Its specific fabrication and structure are as follows:
[0045] First, a piece of high-strength tempered glass with a preferred thickness of 4mm is provided as the substrate layer 11.
[0046] Next, a nanoscale medium-entropy semiconductor nanofilm is deposited on the surface of the substrate layer 11 as a conductive layer 12 using a magnetron sputtering process. This conductive layer 12 can be made of materials such as ITO, FTO, or GZO, and its sheet resistance is preferably controlled at 10-20 Ω / □ (e.g., 15 Ω / □) to ensure good electrothermal conversion efficiency. Its visible light transmittance can reach more than 80%, thereby ensuring the transparency of the heating area.
[0047] Then, to further enhance safety, a portion of the conductive material was etched away at the four edges of the conductive layer 12 using laser etching, forming a 10mm wide non-conductive insulating area. This insulating area, through physical isolation, completely eliminates the risk of current leakage to the frame.
[0048] Subsequently, silver paste with a line width of 5 mm is printed as electrodes 13 at both ends of the conductive layer 12 using a screen printing process, and then soldered out as lead wires after drying and curing.
[0049] Finally, a 0.1 mm thick, high-temperature resistant PET film with adhesive backing is applied to the surface of the conductive layer 12 and the electrode 13 as an encapsulation layer 14, which serves to insulate, waterproof and protect the conductive layer.
[0050] Through the above structure and process, the resulting monolithic heating glass exhibits uniform heating across its entire surface, with a temperature difference controllable within 3°C. When current flows through electrode 13 and then through the conductive layer 12, which acts as a resistive element, electrical energy is efficiently converted into heat energy, which is then evenly dissipated in the form of far-infrared radiation and thermal convection, achieving efficient heating.
[0051] To constitute a fully functional product, this embodiment also includes necessary auxiliary components. An intelligent controller 4 is installed on one side of the frame assembly 2. This controller is electrically connected to the electrodes 13 of the transparent heating element 1 via internal wires, and is used to receive external power and supply power to the heating element. The controller has a built-in microprocessor unit and power regulation circuit, and is connected to dual NTC temperature sensors (accuracy ±0.3℃) to monitor the surface and ambient temperatures in real time. Users can use the touchscreen or buttons on the controller to achieve power adjustment, constant temperature control, and timer switching functions within the range of 200W to 2000W. To ensure safety, the controller also has a built-in overheat protection module and a temperature fuse, providing double protection. When the surface temperature of the heating element is detected to exceed 115℃, the power supply is automatically cut off.
[0052] A base assembly 5 is connected to the bottom of the frame assembly 2, which includes two base brackets 51 and four polyurethane universal casters 52 with a diameter of φ50mm mounted on the base brackets 51. The casters are equipped with a braking device, which allows users to easily move the heater in different spaces and park it stably.
[0053] In summary, this utility model, through its innovative modular frame design combined with a highly efficient double-glass convection structure, successfully solves the technical pain point of existing transparent heaters that, while achieving efficient heating, struggle to balance ease of maintenance. Its ingenious structural design not only ensures the product's stability and safety but also endows it with excellent maintainability, giving it significant practical value and market competitiveness.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
