Description

Technical Field

[0001] The utility model relates to the technical field of electric heating plates, in particular to an electric heating plate which is easy to replace. Background Art

[0002] Electric heating plates, due to their high efficiency, safety, and environmentally friendly characteristics, play an important role in various fields and are one of the indispensable heating elements in modern life. Electric heating plates are widely used in various fields, including household appliances, machinery and equipment, and industrial and agricultural heating applications. The quality of electric heating plates directly affects the lifespan of heating appliances. After a period of use, traditional electric heating plates are prone to bending and deformation near the heating tubes due to the large distance between the edge of the plate and the heat concentration near the heating tubes. Electric heating plates are usually integrated in design, which makes it impossible to repair them once damaged, and they have to be replaced with new ones, which is a huge waste. Therefore, they need to be improved. Utility Model Content

[0003] Based on this, it is necessary to provide an electric heating plate that is easy to replace because after the traditional electric heating plate has been used for a period of time, the distance between the edge of the plate and the electric heating tube is large, and the heat is concentrated near the electric heating tube, so the plate is prone to bending and deformation near the electric heating tube. The electric heating plate usually adopts an integrated design, which means that once it is damaged, it cannot be repaired and has to be replaced with a new one, which causes a great waste.

[0004] The utility model provides an easily replaceable electric heating plate, comprising:

[0005] A chassis, comprising a first groove, a clamping slot and a through hole, wherein the clamping slot is located at an edge of the chassis, and the through hole is located at a center of the chassis;

[0006] The heating tube is clamped in the first groove, and the free end thereof passes through the through hole;

[0007] A panel is located on the surface of the chassis and has a snap ring at the bottom, and the outer diameter of the panel is the same as the outer diameter of the chassis;

[0008] When the clamping ring is clamped in the clamping groove, both the clamping ring and the chassis are provided with screw holes.

[0009] In one embodiment, a second groove is provided at the bottom of the panel, a reinforcing rib is fixedly connected to the inner wall of the panel, and a gap is left between the panel and the heating tube.

[0010] In one embodiment, the reinforcing ribs are cross-arranged in the second groove, and both ends of the reinforcing ribs extend to the inner side wall of the panel.

[0011] In one embodiment, the panel includes a first end face, a second end face and a turning face, the turning face is located between the first end face and the second end face, the cross-sectional outer diameter of the first end face gradually increases toward the turning face, and the cross-sectional outer diameter of the turning face gradually decreases toward the second end face, and the second end face is close to the chassis.

[0012] In one embodiment, the first end surface has texture.

[0013] In one embodiment, the outer diameter of the second end surface is the same as the outer diameter of the chassis.

[0014] In one embodiment, the heating tube includes a bending portion, a turning portion and a docking portion, the bending portion is located in the first groove, the docking portion is located in the through hole, the docking portion and the bending portion are perpendicular to each other, and the bending portion is mirror-symmetrical.

[0015] In one embodiment, a docking joint is fixedly connected to the bottom of the chassis, the docking joint is coaxial with the through hole, and the end of the heating tube is located in the docking joint.

[0016] When assembling the above-mentioned easily replaceable electric heating plate, it is only necessary to pass the free end of the heating tube through the through hole and clamp the heating tube in the first groove, then clamp the clamping ring in the clamping groove, and screw the screws into the corresponding screw holes on the clamping ring and the chassis, so as to facilitate fixing the panel on the chassis. The operation is simple and easy to use. When the panel is damaged, it is only necessary to unscrew the screws to separate the panel and the chassis, which facilitates maintenance, saves resources and avoids waste.

[0017] By fixing reinforcing ribs on the inner wall of the panel, the strength of the panel can be improved. At the same time, since there is a gap between the panel and the heating tube, the temperature of the panel edge can be compensated by the hot air near the heating tube, so that the temperature distribution on the panel surface is uniform, thereby reducing the bending deformation of the panel and increasing the service life of the panel.

[0018] By setting the texture on the surface of the panel, on the one hand, the surface area of ​​the first end face is increased, which helps to improve the heat dispersion and transfer efficiency. At the same time, by increasing the surface area, the electric heating plate can dissipate heat more effectively, which is very important for preventing overheating and improving safety. On the other hand, the fine texture can ensure that the heat is more evenly distributed on the surface of the panel, which is especially important for electrical appliances that require uniform heating.

The term "and / or" used in the specification of this utility model includes any and all combinations of one or more of the relevant listed items.

[0032] The following combination Figure 1-Figure 5 The utility model describes an electric heating plate which is easy to replace.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, an easily replaceable electric heating plate includes a base plate 100 , a heating tube 200 and a panel 300 .

[0034] The chassis 100 has a first groove 110 , a latching slot 120 and a through hole 130 . The latching slot 120 is located at an edge of the chassis 100 , and the through hole 130 is located at a center of the chassis 100 .

[0035] The heating tube 200 is clamped in the first groove 110 , and the free end of the heating tube 200 passes through the through hole 130 .

[0036] The panel 300 is located on the surface of the chassis 100 , and a snap ring 310 is provided at the bottom of the panel 300 . The outer diameter of the panel 300 is the same as the outer diameter of the chassis 100 .

[0037] When the snap ring 310 is snapped into the slot 120 , both the snap ring 310 and the chassis 100 have screw holes 320 .

[0038] When assembling the easily replaceable electric heating plate, it is only necessary to pass the free end of the heating tube 200 through the through hole 130, and clamp the heating tube 200 in the first groove 110, then clamp the clamping ring 310 in the clamping groove 120, and screw the screws into the corresponding screw holes 320 on the clamping ring 310 and the chassis 100, so as to facilitate fixing the panel 300 on the chassis 100. The operation is simple and easy to use. When the panel 300 is damaged, it is only necessary to unscrew the screws to separate the panel 300 from the chassis 100, thereby facilitating maintenance, saving resources and avoiding waste.

[0039] In this embodiment, after a traditional electric heating plate has been used for a period of time, the distance between the edge of the panel 300 and the heating tube 200 becomes larger, and the heat is concentrated near the heating tube 200, so the panel 300 is easily bent and deformed near the heating tube 200. Therefore, a second groove 330 is provided at the bottom of the panel 300, and a reinforcing rib 340 is fixedly connected to the inner wall of the panel 300, leaving a gap between the panel 300 and the heating tube 200.

[0040] It should be supplemented that the reinforcing ribs 340 are cross-arranged in the second groove 330 , and both ends of the reinforcing ribs 340 extend to the inner side wall of the panel 300 .

[0041] By fixing the reinforcing ribs 340 on the inner wall of the panel 300, the strength of the panel 300 can be improved. At the same time, since there is a gap between the panel 300 and the heating tube 200, the temperature of the edge of the panel 300 can be compensated by the hot air near the heating tube 200, so that the temperature distribution on the surface of the panel 300 is uniform, thereby reducing the bending deformation of the panel 300 and improving the service life of the panel 300.

[0042] like Figure 1 、 Figure 3 and Figure 4As shown, in one embodiment, the panel 300 includes a first end face 350, a second end face 360 ​​and a turning face 370, and the turning face 370 is located between the first end face 350 and the second end face 360. The cross-sectional outer diameter of the first end face 350 gradually increases toward the turning face 370, and the cross-sectional outer diameter of the turning face 370 gradually decreases toward the second end face 360, and the second end face 360 ​​is close to the chassis 100.

[0043] During the use of the electric heating plate, some water droplets sometimes flow from the appliance onto the panel 300. In order to prevent the water droplets from flowing into the first groove 110 and affecting the service life of the heating tube 200, the first end surface 350 and the turning surface 370 are provided to conveniently lead the water droplets to the outside of the chassis 100, which can effectively reduce the water droplets from flowing into the chassis 100 and improve the service life of the electric heating plate.

[0044] In this embodiment, the first end surface 350 has a texture 380. On the one hand, the texture 380 increases the surface area of ​​the first end surface 350, which helps to improve the heat dispersion and transfer efficiency. At the same time, by increasing the surface area, the electric heating plate can dissipate heat more effectively, which is very important for preventing overheating and improving safety. On the other hand, the fine texture 380 can ensure that the heat is more evenly distributed on the surface of the panel 300, which is particularly important for electrical appliances that require uniform heating.

[0045] It should be additionally explained that the outer diameter of the second end surface 360 ​​is the same as the outer diameter of the chassis 100 .

[0046] In this embodiment, the heating tube 200 includes a bending portion 210, a turning portion 220 and a docking portion 230. The bending portion 210 is located in the first groove 110, and the docking portion 230 is located in the through hole 130. The docking portion 230 and the bending portion 210 are perpendicular to each other, and the bending portion 210 is mirror-symmetrical. By spreading the bending portion 210 throughout the first groove 110, the heating uniformity of the panel 300 can be easily improved.

[0047] In this embodiment, a docking joint 240 is fixedly connected to the bottom of the chassis 100, and the docking joint 240 is coaxial with the through hole 130. The end of the heating tube 200 is located in the docking joint 240. The provided docking joint 240 facilitates the connection of the heating tube 200 with the electrical appliance, thereby facilitating the application of the electric heating plate in various electrical appliances.

[0048] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and improvements are possible within the scope of the present invention, as would be apparent to one skilled in the art. These variations and improvements fall within the scope of the present invention. Therefore, the scope of the present invention shall be determined by the appended claims.
