[0001] The utility model relates to the technical field of household appliances, and particularly relates to a household appliance front shell assembly and a fan heater. BACKGROUND
[0002] The household appliance front shell assembly of the fan heater is an important external structural component of the fan heater, mainly bearing multiple functions such as protection, air guiding and aesthetic decoration. It mainly consists of two core components, a plastic front shell and a metal front mesh. The plastic front shell is usually made of engineering plastics such as ABS and PP by injection molding to provide a basic support structure, and the metal front mesh is usually a stamped metal mesh that has protection and heat dissipation functions.
[0003] In the design of the conventional household appliance front shell assembly of the fan heater, the metal front mesh needs to be fixedly connected to the plastic front shell through multiple bent edges. This assembly process requires the operator to manually complete the insertion and bending fixation of the bent edges one by one, which is low in assembly efficiency and high in labor cost. SUMMARY

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0031] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to the numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and it does not indicate the relationship between the various embodiments and / or settings discussed.
[0032] For the convenience of description, spatial relative terms can be used herein to describe the relative position relationship or movement condition of one element or feature relative to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", and the like. Such spatial relative terms are used to include different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is flipped over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" other elements or features will be subsequently oriented as "above" or "above" other elements or features. Therefore, the example term "below" can include both the upper and lower positions. The device can be additionally oriented (rotated by 90 degrees or in other directions) and the spatial relative relationship descriptors used herein are interpreted accordingly.
[0033] Embodiment one
[0034] The present embodiment provides a front shell assembly of a household appliance, as shown in the drawings, comprising: a front net 1, a bracket 3 and a front shell 2, the front net 1 comprises a front net body 4 and a plurality of bending pieces 5 distributed on the circumferential edge of the front net body 4; the front net body 4 is arranged on one side of the bracket 3, and the outer contour size of the front net body 4 is matched with the bracket 3, the bending piece 5 extends outward from the edge of the front net body 4, and the extension length exceeds the bracket 3. Figures 1-7 In the present embodiment, during assembly, first, the front net body 4 is placed on one side of the bracket 3, ensuring that the outer contour of the front net body 4 completely matches the bracket 3, and attention should be paid to aligning the bending pieces 5 on the circumferential edge of the front net 1 with the corresponding positions of the bracket 3, at this time the bending pieces 5 extend outward from the edge of the front net body 4, and the extension length exceeds the bracket 3, facilitating subsequent assembly.
[0035] Then, the bending pieces 5 are bent by using a jig or automatic equipment to clamp the front net body 4 on the bracket 3 through the bending pieces 5. Finally, the assembled combination of the front net body 4 and the bracket 3 is connected with the front shell 2. Compared with the traditional assembly scheme of the warm air blower, the present embodiment introduces the "bracket 3" as an intermediate connecting piece, forming a three-layer structure of "front net 1-bracket 3-front shell 2", simplifying the assembly process, and the bending pieces 5 only need to cooperate with the bracket 3. The bracket 3 provides a unified positioning reference as an intermediate piece, facilitating automatic assembly. Moreover, due to the presence of the bracket 3, the structure of the mesh cover 7 and the bracket 3 can be flexibly designed, without the need to change the front shell 2, i.e. the design flexibility is higher.
[0036]
[0037] Further, the front mesh body 4 comprises a front mesh frame 6 and a mesh cover 7, the mesh cover 7 is arranged in the front mesh frame 6, the front mesh frame 6 provides stronger structural support for the mesh cover 7; the bending piece 5 is connected with the front mesh frame 6, due to the support of the front mesh frame 6, the structural deformation of the bending piece 5 during bending is avoided.
[0038] The bending piece 5 is inclined from the edge of the front mesh body 4 to the inside of the front mesh frame 6, and the inclination angle is 20 degrees. When the front mesh body 4 is aligned and attached with the support 3, the inwardly inclined bending piece 5 forms a pre-fixing effect between the front mesh body 4 and the support 3, and provides guidance for subsequent bending operation, facilitating bending. The inclination angle of 20 degrees not only ensures the pre-fixing and guiding effect of the bending piece 5, but also provides sufficient expansion space for the bending piece 5, so that it can be effectively connected with the support 3.
[0039] Further, the mesh cover 7 and the front surface of the support 3 are designed with arc surfaces, forming a unified curved surface transition. The arc surface design not only optimizes the overall appearance of the product, but also enables the bending piece 5 to naturally abut the arc surface of the support 3 when the front mesh body 4 is aligned and attached with the support 3, facilitating the clamping and fixing with the support 3.
[0040] Further, the support 3 comprises a support plate 8 and a connecting assembly 9, the front surface of the support plate 8 is attached with the front mesh body 4, the connecting assembly 9 is arranged on the back surface of the support plate 8, and the connecting assembly 9 is connected with the front shell 2. The support plate 8 provides a stable attachment surface and can support the front mesh body 4.
[0041] Specifically, the connecting assembly 9 comprises a limiting frame 10 and a fixed column 11, the limiting frame 10 is matched with the inner frame of the front shell 2, and the fixed column 11 is connected with the front shell 2. Through the limiting frame 10, the front mesh body 4 and the support 3 can be more conveniently aligned and attached.
[0042] The connecting assembly 9 further comprises a limiting convex rib 12, the front surface of the front shell 2 is provided with a limiting groove, and the limiting convex rib 12 is connected with the limiting groove. The limiting convex rib 12 and the limiting groove further improve the stability of the connection between the front shell 2 and the support 3.
[0043] Further, the limiting convex rib 12 is provided with two limiting convex ribs, which are respectively arranged on the upper and lower sides of the limiting frame 10.
