Description

Technical Field

[0001] This utility model relates to the field of electric heater technology, and in particular to an electric heater structure that is easy to maintain. Background Technology

[0002] Electric heaters, as a common household heating device, primarily function by converting electrical energy into heat energy through heating elements to provide indoor heating. To ensure safety, electric heaters are typically equipped with fuses and circuit breakers as circuit protection devices. However, existing electric heater protection circuit designs have significant shortcomings: firstly, the fixed installation locations and enclosed structures of the protection components make later maintenance and replacement extremely inconvenient; secondly, the protection devices are usually installed on the side panel or surface of the heater casing, too far from the heating elements to detect abnormal operating conditions in a timely manner, thus failing to achieve rapid response protection. Utility Model Content

[0003] To address the problems mentioned above, this utility model provides an easy-to-maintain electric heater structure that is easy to repair, can provide rapid response protection, and is easy to move.

[0004] The solution adopted by this utility model to solve its technical problem is: an easy-to-maintain electric heater structure, including a shell assembly, a heating element is disposed inside the shell assembly, a support frame is fixedly connected to the top of the heating element, and an installation cavity is provided on the top of the support frame;

[0005] A boss is provided inside the mounting cavity. The boss is fixedly connected to the outer shell assembly. A handle is formed on the side of the boss facing the outside of the outer shell assembly. A protective component is provided on the side of the boss away from the handle. The protective component is electrically connected to the heating component.

[0006] Furthermore, the protection component includes a fuse and a circuit breaker, the fuse being electrically connected to the circuit breaker;

[0007] A mounting plate is fixedly connected to one side of the boss, the circuit breaker is located on the top of the mounting plate, and the fuse is fixed to the bottom of the boss.

[0008] Furthermore, the housing assembly includes a base, a rear shell, a protective mesh, and a top cover;

[0009] The rear shell is fixed to the top of the base, the protective net is fixed to one side of the rear shell, the support frame is fixedly connected to the rear shell, and the top cover is fixed to the top surface of the rear shell and located on the top of the boss.

[0010] Furthermore, the heating element includes an electric heating tube.

[0011] Furthermore, the heating element also includes a heat dissipation element, which is disposed at the bottom of the heating element.

[0012] In summary, the beneficial effects of this utility model are as follows: a boss is provided in the mounting cavity at the top of the electric heater, which is fixedly connected to the outer shell assembly. One side of the boss can form a handle, which makes it easy for users to move the electric heater. At the same time, a protective component is provided on the other side of the boss. By separating the protective component into the mounting cavity, it is easy for users to replace and repair the protective component later. In addition, the protective component is located on the top of the heating element, which can sense the working status of the heating element in a very short time and realize rapid response protection.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0018] To make the content of this utility model easier to understand, the present utility model will be further described below with reference to specific embodiments and accompanying drawings.

[0019] It should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "inner," and "outer" used herein to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Unless otherwise stated, "a plurality of" means two or more.

[0020] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figures 1 to 3 As shown, an easy-to-maintain electric heater structure includes a shell assembly, inside which a heating element 1 is disposed. The heating element 1 includes an electric heating tube 11 and a reflector plate. A support frame 2 is fixedly connected to the top of the electric heating tube 11. The support frame 2 is made of heat insulation material and has an installation cavity at the top.

[0022] like Figure 2 and Figure 3 As shown, the outer casing assembly includes a base 5, a rear shell 6, a protective net 7, and a top cover 8. The rear shell 6 is fixed to the top of the base 5 by screws, the protective net 7 is fixed to the front side of the rear shell 6, the heating element 11 and the reflector are both disposed between the rear shell 6 and the protective net 7, and the top and bottom of the rear shell 6 are provided with support frames 2 and mounting cavities.

[0023] The top mounting cavity is provided with a boss 3, which is fixedly connected to the rear shell 6 by screws. A handle 31 is formed on the side of the boss 3 facing the outside of the rear shell 6, which allows the user to carry the electric heater and move the electric heater.

[0024] like Figure 3 As shown, in this embodiment, a protective component 4 is provided on the side of the boss 3 away from the handle portion 31, and the protective component 4 is connected to the heating element 11. The protective component 4 in this embodiment includes a temperature sensor, a fuse 41, and a circuit breaker 43, and the fuse 41 is electrically connected to the circuit breaker 43.

[0025] A mounting plate 42 is fixedly connected to the side of the boss 3 away from the rear housing 6 by screws. A circuit breaker 43 is located on the top of the mounting plate 42, and a fuse 41 is fixed to the bottom of the boss 3. The top of the boss 3 is also provided with a top cover 8, which is screwed to the rear housing 6.

[0026] With the above design, users can inspect, repair, and replace the protective component 4 by disassembling the boss 3 or the top cover 8. Furthermore, since the protective component 4 is located on top of the heating element 11, it can sensitively sense the operating status of the electric heater and achieve a rapid response.

[0027] like Figure 1 and Figure 3As shown, a heat dissipation assembly 12 is provided in the mounting cavity at the bottom of the rear shell 6. The heat dissipation assembly 12 includes a cooling fan and a heat sink. The cooling fan is used to accelerate the heat transfer and improve the indoor heating efficiency.

[0028] By optimizing the internal structure of the electric heater, the protective component 4 is centrally located at the top of the device, while the heat dissipation system is integrated into the bottom area. This modular and partitioned layout of functional components not only achieves more efficient heat dissipation performance but also significantly improves the maintainability of the electric heater, making daily maintenance and component replacement more convenient.

[0029] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
