Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more particularly to a reflector structure. Background Technology

[0002] As people's demands for quality of life continue to rise, electric heaters, as one of the essential devices for heating in winter, have been widely used in homes, offices, and other places. However, in traditional electric heaters, the edges of the reflector are directly screwed to the heater casing via a horizontal plate. This not only prevents radiation scattering at the edges of the reflector but also easily leads to stress concentration, which can cause deformation or cracking with long-term use, affecting the lifespan of the reflector. Utility Model Content

[0003] To address the problems mentioned above, this invention provides a novel electric heater reflector structure that improves heat energy utilization, reduces stress concentration at the reflector edge, and extends the reflector's service life.

[0004] The solution adopted by this utility model to solve its technical problem is: a reflector structure, including two symmetrically arranged reflective surfaces, with a chamfer between the two reflective surfaces, and a stepped structure provided on the side of the reflective surface away from the chamfer.

[0005] Furthermore, the longitudinal intercept of the reflecting surface satisfies the parabolic equation Y. 2 =2PX, where P = 2F, and F is the focal length of the reflecting surface.

[0006] Furthermore, the stepped structure includes a vertical portion and a horizontal portion, with the vertical portion disposed between the reflective surface and the horizontal portion.

[0007] Furthermore, a connector is provided on the outer side of the transverse portion.

[0008] This application also provides an electric heater, including a heating element, a reflector, and a mesh surface, wherein the heating element is located between the reflective surface of the reflector and the mesh surface, and the mesh surface is fixedly connected to the reflector.

[0009] In summary, the beneficial effects of this utility model are as follows: The reflector of this application has a stepped structure on its side, which includes a horizontal part and a vertical part. The horizontal part can scatter radiation at the edge, improving heat energy utilization. At the same time, the vertical part can serve as a transition area, connecting the reflective curved surface and the horizontal part, allowing the load to be smoothly transferred from the curved surface to the horizontal part, avoiding a sudden increase in stress at the edge, and improving the overall deformation resistance and service life of the reflector. In addition, a plug-in piece is provided on the outer side of the horizontal part, through which the reflector can be positioned, facilitating user installation.

[0010] The above description is merely an overview of the technical solution of this utility model. 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] like Figures 1 to 4As shown, a reflector 1 structure includes two symmetrically arranged reflective surfaces 11. The intersection of the two reflective surfaces 11 is chamfered 12 to make the surface of the reflector 1 smoother, reduce heat loss and improve its appearance. A stepped structure 13 is provided on the side of the reflective surface 11 away from the chamfer 12.

[0020] The parameters of the reflective surface 11 in this embodiment are obtained by formula Y. 2 =2PX is calculated to form the basic cross-sectional shape of the reflecting surface 11, where P = 2F and F is the focal length of the reflecting surface 11.

[0021] like Figure 1 As shown, the stepped structure 13 includes a vertical portion 131 and a horizontal portion 132, with the vertical portion 131 positioned between the reflective surface 11 and the horizontal portion 132. The horizontal portion 132 can scatter radiation at its edges, reducing the temperature rise on the sides and guiding more heat towards the front for reflection. Simultaneously, the vertical portion 131 serves as a transition area, connecting the reflective surface 11 and the horizontal portion 132, allowing the load to be smoothly transferred from the surface to the horizontal portion 132, preventing a sudden increase in stress at the edges, and improving the overall deformation resistance and service life of the reflector 1.

[0022] like Figure 2 As shown, a connector 133 is provided on the outer side of the horizontal portion 132. With the above arrangement, the reflector 1 can be positioned by the connector 133, which facilitates user installation.

[0023] like Figure 3 and Figure 4 As shown, this embodiment also includes an electric heater, comprising a heating element 2, a reflector 1, and a mesh surface 3. The heating element 2 is located between the reflective curved surface 11 of the reflector 1 and the mesh surface 3, and the mesh surface 3 is fixedly connected to the reflector 1. Specifically, in this embodiment, the X parameter of the reflective curved surface 11 is 18 mm, the Y parameter is 51.3 mm, and the center distance between the two heating elements 2 is set to 54 mm to ensure that the heat can be evenly distributed and effectively radiated into the space ahead.

[0024] Optionally, in this embodiment, the horizontal portion 132 of the stepped structure 13 is provided with serrated microchannels, which are microgrooves formed by laser etching. The vertical portion 131 can be embedded with a phase change material, such as paraffin, to absorb excess heat, and the heat dissipation area is increased through the edge serrated microchannels, thereby achieving the dual functions of overheat protection and waste heat recovery.

[0025] 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.
