Description

Technical Field

[0001] The invention relates to the technical field of indoor heating equipment, in particular to a skirting board with a PTC heating structure. Background Art

[0002] As a transitional decorative component between indoor walls and floors, skirting boards not only beautify spaces and protect corners, but have also been widely used in terms of multifunctionality in recent years. Among them, skirting boards with heating functions are gradually favored by the market due to their space saving, aesthetics, and uniform heating characteristics. However, the current heating skirting board technology still has many shortcomings.

[0003] Existing heating skirting boards mainly use electric heating wires or hot water circulation systems as heat sources. Although the electric heating wire method has a certain heating efficiency, it has problems such as high power consumption, safety hazards caused by material aging, and inaccurate temperature control; while the hot water circulation system needs to be equipped with a complex pipeline and pump system. Once a failure occurs, it is difficult and expensive to repair. In addition, the size of existing skirting board heating equipment is relatively fixed, and it is difficult to customize it according to the space requirements of different houses, resulting in uneven heat distribution, which further affects the heating effect and user experience.

[0004] With the development of material technology, heating elements based on positive temperature coefficient (PTC) characteristics have attracted much attention due to their automatic temperature control function. PTC elements can automatically adjust the resistance value according to temperature changes, thereby effectively preventing overheating problems and have the characteristics of energy saving and safety. However, how to efficiently integrate PTC heating technology into skirting boards while taking into account heat dissipation efficiency, structural stability, flexible size adjustment, and installation and maintenance convenience is still a topic worthy of in-depth research. Summary of the invention

[0005] In view of the above problems, the present invention proposes an innovative skirting board structure based on PTC heating elements. By optimizing the heat dissipation structure, modular and shear-type design, and the connection method of plug-in electrodes, it provides an energy-saving, safe, efficient solution that can flexibly adapt to the needs of different house spaces, and provides a new idea for the research and development and application of modern heating skirting boards.

[0010] Shell: The shell is an external protective shell, the length of which is flexibly determined according to the length of the PTC heating strip, and is used to accommodate the PTC heating strip and the heat dissipation fence.

[0011] Furthermore, the PTC heating strip is composed of a heat-conducting layer and a PTC heating element. The heat-conducting layer is formed by integrally extruding a high thermal conductivity metal rectangular tube in an internal cavity, which can improve heat transfer efficiency and protect the PTC heating element.

[0012] Furthermore, the PTC heating element is a rectangular body structure, with plug-in electrodes provided at the bottom and elastic buckles provided at the plug-in interface, which are automatically locked during plug-in to ensure that they will not loosen. Multiple PTC heating elements can be plugged in parallel to achieve quick electrical connection.

[0013] Furthermore, the heat dissipation fence is composed of a plurality of rectangular heat dissipation blade plates with oblique cuts arranged horizontally, and a guide groove is provided between two adjacent surfaces of the heat dissipation blade plates for guiding hot air to flow outward. A plurality of heat dissipation blades are arranged in sequence inside the heat dissipation blade plates, and the heat dissipation blade plates and the heat dissipation blades are preferably integrally formed.

The common housing in the present invention is a style with vertical heat dissipation holes or heat dissipation strips on the front, heat dissipation holes or heat dissipation strips on the top surface at an inclined angle, and can be cut to length; a plurality of buckle grooves are arranged on the inner side of the housing 3 to fix the heat dissipation grille 2 so that it remains stable after installation and is not easy to loosen.

[0036] Example 2: Construction of PTC heating strip

[0037] like Figure 2 , Figure 3 As shown, the PTC heating strip 1 is a rectangular strip, which is composed of a heat-conducting layer 11 and a PTC heating element 12. The heat-conducting layer 11 is coated on the outside of the PTC heating element 12, and the PTC heating element 12 is used in parallel. The PTC heating strip 1 can be used in multiple lengthened strips. Specifically: the PTC heating strip 1 can be connected and lengthened by two or more PTC heating strips 1 according to the specific space requirements of the house, and the length of the PTC heating strip 1 can be determined independently by shearing, and then the length of the skirting board is determined; to meet the different requirements of different room sizes; the heat-conducting layer 11 is made of a metal material with high thermal conductivity, preferably aluminum alloy in this embodiment, to ensure that heat can be quickly transferred from the PTC element 12 to the heat dissipation fence 2, the heat-conducting layer 11 is an aluminum alloy rectangular tube with an internal cavity, which is made by an integrated extrusion process, and its tube wall thickness is not less than 3mm, and the outer surface of the heat-conducting layer 11 is provided with an anti-corrosion coating to extend the protection service life of the internal PTC element 12.

[0038] The PTC heating element 12 is arranged in the internal cavity of the heat-conducting layer 11. The characteristics of the PTC heating element 12 used in this embodiment are that the power supply is DC 12V or AC 220V, the temperature is 80°C, the temperature control and temperature maintenance, and the rectangular body structure; the upper, lower, left and right four surfaces of the rectangular body are wrapped with an insulating film, and a concave electrode hole is reserved at the back of the heating element 12, and a protruding plug-in electrode 121 is reserved at the front. The number of connections of the heating element 12 can be determined according to the length of the skirting board and the area of ​​the house, and two or more heating elements can be connected in parallel for use; the core of the PTC heating element 12 is a heating material with a positive temperature coefficient characteristic; the resistance value of the material will increase with the increase of temperature, thereby realizing automatic temperature adjustment and avoiding overheating problems.

[0039] Embodiment 3: Connection method of plug-in electrodes and power supply

[0040] like Figure 3 , Figure 4 As shown, a pair of plug-in electrodes 121 are provided at the bottom of the PTC heating element 12. The pair of plug-in electrodes 121 adopt a standardized plug-in structure, and the connection method is as follows.

[0041] Modular design: The inside of the plug-in electrode 121 is an independent module, which is fixedly connected to the PTC heating element 12 by welding; the welding points are subjected to secondary treatment to ensure electrical stability and mechanical firmness under long-term use.

[0042] Plug-in connection: the plug-in electrodes 121 are of a bidirectional conductive structure, and the protruding electrode plug of the rear PTC heating element 12 can be quickly inserted into the concave electrode interface of the front PTC heating element 12 to achieve a quick parallel connection.

[0043] Self-locking function: After the protruding electrode is inserted, the elastic buckles on both sides of the internal concave electrode interface will automatically lock, ensuring a stable electrical connection and will not loosen even if the device moves or vibrates.

[0044] The power supply is connected by using a special jumper wire to connect the skirting boards of the PTC heating structure of the present invention, so the line connection of the whole room can be quickly completed; when supplying power, the user only needs to insert the plug of the plug-in electrode into the external power supply interface through the special transition power connection line, without the need to use tools or perform complicated wiring operations, and the process is fast and convenient.

[0045] Example 4: Structural Optimization of Heat Dissipation Fence

[0046] The heat dissipation fence 2 is the core heat dissipation component of the PTC heating structure, and its structural design directly affects the performance of the heating device. Figure 2 , Figure 5As shown, the heat dissipation grille 2 of this embodiment is made of aluminum alloy, a metal material with high thermal conductivity, and its structural features are as follows.

[0047] Blade plate structure: The heat dissipation fence 2 is composed of multiple heat dissipation blade plates 21, which are rectangular with an upward oblique cut of a certain thickness. The interior of the heat dissipation blade plate 21 is arranged with multiple heat dissipation blades 211 arranged in sequence to increase the heat dissipation area to ensure the effect of temperature control and heat dissipation; the spacing between the thin plates is precisely calculated to ensure the balance between the retention and transfer of heat energy; the manufacturing process of the heat dissipation blade plate 21 and the heat dissipation blade 211 is preferably integrated molding.

[0048] Guide design: Multiple heat dissipation blades 21 are horizontally penetrated by the PTC heating strip 1 and arranged equidistantly. A guide groove is formed between two adjacent surfaces of the heat dissipation blade 21 to guide the hot air to flow outward. The four sides of the heat dissipation blade 21 dissipate heat to the surroundings at the same time, forming a heat wave circle to improve the convective heat dissipation efficiency.

[0049] Fixing method: The bottom of the heat dissipation grille 2 is fixed in the slot of the shell 3 by threaded connection, and the top is tightly fitted with the shell 3 by elastic fasteners, thereby enhancing the overall stability.

[0050] Example 5: Housing installation method

[0051] The design focus of the housing 3 is to protect the internal components and facilitate installation and maintenance. Figure 1 The specific installation method is as follows.

[0052] Split structure: The housing 3 is composed of two parts, namely the front housing and the rear housing, which are assembled into one by snap connection. The split design is convenient for users to quickly disassemble and inspect the internal components.

[0053] Installation and fixing: A plurality of screw holes are arranged on the back side of the housing 3 against the wall for fixing screws or hanging skirting boards.

[0054] Protection design: Heat dissipation holes are opened on the shell surface, and a small-pore mesh protective cover is set inside the shell surface, which can not only ensure smooth heat dissipation, but also prevent foreign objects or insects from entering and affecting the operation or use of the equipment.

[0055] Example 6: Comprehensive working principle

[0056] When current flows through the PTC heater, the temperature inside the PTC material will increase with the increase of current. Once the temperature reaches a certain level, the resistance inside the PTC material will increase sharply with the increase of temperature, thereby greatly reducing the current and achieving the purpose of automatic temperature regulation. The advantages of PTC heating are its safety, compact structure, small size, high heating efficiency, good reliability, continuous operation, good durability, ability to withstand large current loads, controllable heating temperature, and low risk of burning.

[0057] When the skirting board of the PTC heating structure of the present invention is energized, the current enters the PTC heating element 12 through the plug-in electrodes 121 ; the heating element gradually heats up due to its positive temperature coefficient characteristic, and at the same time the heat conductive layer 11 quickly transfers the generated heat to the heat dissipation fence 2 .

[0058] The heat dissipation fence 2 disperses the heat evenly into the surrounding air through the heat dissipation blade structure and the guide groove design, forming an efficient convection heat dissipation effect. The heat dissipation holes on the outside of the shell 3 further enhance the air circulation and ensure the stable operation of the equipment.

[0059] The present invention not only improves the heating efficiency and safety of the device, but also significantly simplifies installation and maintenance through modular and standardized connection design. The overall structure is sturdy and durable, suitable for heating needs in various home and office environments.
