Description

Technical Field

[0001] The utility model belongs to the technical field of electric heaters, and in particular relates to an electric heater with four independently controllable heating elements. Background Art

[0002] Electric heaters are a common heating device used in homes, offices, and public facilities. Their operating principle typically relies on an internal electric heating element, which generates heat through power, thereby raising the ambient temperature. However, while traditional electric heaters offer effective heating capabilities, they still have many shortcomings in practical use.

[0003] Most traditional electric heaters use a unified heating mode, with multiple heating elements typically designed to operate simultaneously, preventing users from flexibly adjusting the heating mode based on actual needs. This design leads to energy waste, especially when full-area heating is not required. However, all heating elements still operate simultaneously, unnecessarily increasing power consumption, reducing energy efficiency, and increasing electricity costs.

[0004] Because electric heaters are exposed to high temperatures for extended periods, internal components may become loose or deform due to thermal expansion and contraction. This phenomenon is particularly common with components made of different materials, such as metal and plastic. Prolonged temperature fluctuations can cause structural fatigue in the heater's casing, bracket, or internal components, compromising the overall stability and safety of the device. Structural looseness not only reduces the device's lifespan but also increases safety risks, especially over extended use, potentially causing the heater to fail or become dangerous.

[0005] In view of this, overcoming the defects of the above-mentioned prior art is an urgent problem to be solved in this technical field. Utility Model Content

[0008] Furthermore, the inner two sides of the assembly bracket are respectively provided with installation through-positions, and the two ends of the reinforcement bracket are respectively provided with installation through-holes, the installation through-holes correspond to the installation through-positions, and are connected and fixed by fasteners.

[0009] Furthermore, a number of connecting through-pillars are evenly provided on the inner front side of the assembly bracket, and a number of connecting folded edges are evenly provided on the edge of the front bracket panel. The several connecting folded edges correspond to the several connecting through-pillars one by one, and the surfaces of the several connecting folded edges are provided with connecting through-holes, and fasteners are passed through the connecting through-holes to connect and fix to the connecting through-pillars.
