The utility model provides a face lid subassembly 10 and cooking utensil, this face lid subassembly 10 is used for cooking utensil, and cooking utensil can be 1, microwave oven, the electric rice cooker for electromagnetism stove. Referring to fig. 1, a surface cover assembly 10 applied to an induction cooker 1 is illustrated. The induction cooker 1 has a display assembly having a display area for displaying information related to the operation of the induction cooker 1. The face cover assembly 10 in this embodiment includes a face cover 12 and a window sheet 11, and the display area of the display assembly 20 is disposed on one side of the window sheet 11. The viewing pane 11 is transparent or translucent so that light emitted when the display area displays information can pass through the viewing pane 11 to be viewed by a user.

Please refer to fig. 2 to 4. The face cover assembly 10 in this embodiment includes a face cover 12 and a window sheet 11. The window pane 11 comprises a sheet body 111 and an injection molding 112 arranged along the sheet body circumferential side 1111. The surface cover 12 is formed by injection molding and wrapping the window sheets 11 along the circumferential side surfaces of the window sheets 11, so that a stopping part 121 matched with the injection molding part 112 in shape is formed at the position, contacted with the window sheets 11, on the surface cover 12, the stopping part 121 is clamped with the injection molding part 112, and the window sheets 11 are limited along the thickness direction of the window sheets 11.

Specifically, the window sheet 11 includes a sheet body 111 and an injection molding portion 112 disposed along a circumferential side 1111 of the sheet body. Specifically, the shape of the window sheet 11 may be square, circular or other shapes. The louver 11 may also have a color. The window sheet 11 has a top surface and a bottom surface, and a surface corresponding to the circumferential direction of the window sheet 11 is a circumferential side surface of the window sheet 11, with reference to the orientation of the face cover assembly 10 applied to the induction cooker 1.

Specifically, the face cover 12 and the window sheet 11 in this embodiment are connected by injection molding, that is, by positioning the molded window sheet 11 on a mold for manufacturing the face cover 12, and injecting a liquid encapsulation material for producing the face cover 12 into the mold, the encapsulation material will wrap the window sheet 11 along the circumferential side surface of the window sheet 11, so that after encapsulation, the face cover 12 and the window sheet 11 form the face cover assembly 10 of an integrated structure. It can be understood that, due to the existence of the injection molding part 112, the stopping part 121 is generated during the injection molding process of the face cover 12, so that the shape of the stopping part 121 is complementary to that of the injection molding part 112 and is adapted.

In the present embodiment, the stopping portion 121 is clamped with the injection portion 112, and the clamping force direction of the stopping portion and the injection portion is along the thickness direction of the window sheet 11, so as to limit the window sheet 11 along the thickness direction of the window sheet 11, so that the window sheet 11 cannot be separated from the surface cover 12. Therefore, the connecting force between the window piece 11 and the surface cover 12 not only has the adhesive force generated during encapsulation, but also has the clamping force between the stopping part 121 and the injection molding part 112, so that the embodiment can effectively improve the firmness between the encapsulated window piece 11 and the surface cover 12 and prevent the window piece 11 and the surface cover 12 from being separated due to the action of external force during the relevant destructive test; and the case where the window sheet 11 is deformed and separated from the face cover 12 after long-term use.

In this embodiment, the injection molding part 112 is exposed on the circumferential side surface 1111 of the sheet body, so that in the injection molding process, the encapsulated material wraps the window piece 11 from the periphery of the window piece 11 to form the encapsulated surface cover assembly 10 together with the window piece 11, and therefore, in the injection molding process, there is no high requirement for the injection molding pressure and the flowability of the encapsulated material, and therefore, the requirement for the production process can be reduced in this embodiment, and the yield of the product can be improved.

In this embodiment, due to the arrangement of the injection molding part 112, the encapsulating material wraps the window piece 11 from the circumferential side surface of the window piece 11, that is, the encapsulating material can form a firm connection with the window piece 11, so that a tapered hole does not need to be arranged on the window piece 11, and the surface cover 12 and the window piece 11 are connected in an injection molding manner in a manner of feeding glue through a pinhole; therefore, the embodiment avoids various defects caused by a pinhole glue inlet mode, for example, the overflow amount of a single glue inlet hole is not convenient to control, so that the overflow amount of the encapsulating material is large, and part of the surface of the window piece 11 can be shielded by the overflowing encapsulating material; if other processes are adopted to remove overflowing encapsulating materials, the window piece 11 can be damaged or the surface strength of the window piece 11 is influenced, so that the production process is simplified, and the product yield is improved.

The utility model discloses technical scheme is through the portion 112 of moulding plastics that sets up at window piece 11 lamellar body circumference side 1111 to at the in-process of moulding plastics, rubber coating material wraps up window piece 11 from the circumference side of window piece 11, has also formed the backstop portion 121 that corresponds with the portion 112 of moulding plastics on the face lid 12 that generates simultaneously. The setting of portion 112 of moulding plastics has improved the fastness of rubber coating, and then has improved the connection fastening nature between face lid 12 and the window piece 11, and the effectual condition of having avoided separation in window piece 11 and the face lid 12 when carrying out destructive tests such as cold and hot shock test, drop test to face lid subassembly 10. Meanwhile, the clamping structure of the injection molding part 112 and the stopping part 121 also increases the area of the contact part of the window sheet 11 and the surface cover 12, thereby improving the firmness of encapsulation. Furthermore, as the window sheet 11 is wrapped by the encapsulating material from the circumferential side surface of the window sheet 11, the surface cover 12 and the window sheet 11 do not need to be connected in an injection molding mode through a pinhole glue inlet mode in the injection molding process, so that the injection molding high pressure of a mold and the high flowability requirement of the encapsulating material are reduced, the selection space of the encapsulating material is enlarged, the production process is simplified, and the qualification rate of products is improved. Furthermore, in this embodiment, because the rubber coating material surrounds the circumferential side surface of the window piece 11 from all around, the junction of the surface cover 12 and the window piece 11 formed after the injection molding is completed can be more smooth and seamless, so that the surface cover assembly 10 can be more beneficial to cleaning of the integrated surface cover assembly, particularly in a long-term multi-oil-smoke use environment, foreign matters such as oil stains and dust can be greatly reduced to remain at the junction of the window piece 11 and the surface cover, and therefore the surface cover assembly 10 has better anti-fouling performance.

In this embodiment, the injection molding part 112 may have various shapes, and the thickness of the injection molding part 112 may be the same as or different from the thickness of the sheet body 111 of the window sheet 11. The thickness of the injection molding part 112 is the same as the thickness of the sheet body 111 of the window sheet 11 or larger than the thickness of the window sheet 11, so that the reliability of the clamping between the stopping part 121 and the injection molding part 112 can be improved.

In the following embodiments, the structural form of the injection molding part 112 will be specifically described. It can be understood that, since the stopping portion 121 is formed by encapsulating the injection molded part 112, the shape and the position of the stopping portion 121 follow the corresponding generation of the shape and the position of the injection molded part 112. Therefore, when the structural form of the injection molding part 112 is clear, the structure of the stopper 121 is also clear.

Therefore, the high pressure of the injection molding of the mold and the high flowability requirement of the encapsulating material are further reduced, and the encapsulating dead angle is effectively avoided. And when injection pressure is higher, the encapsulating material can produce the impact to the portion 112 of moulding plastics, and the protruding side 1132 that is the curved surface setting can decompose the impact of encapsulating material effectively, avoids producing the deformation or the damage of concentrated stress and causing window plate 11.

It can be understood that the first chamfer 1133 is also configured to enable the encapsulating material to impact the injection molding portion 112 when the injection pressure is high, and the convex side 1132 configured as a curved surface can effectively decompose the impact force of the encapsulating material, so as to avoid the deformation or damage of the window plate 11 caused by the concentrated stress, and effectively reduce the dead angle of encapsulating.

Please refer to fig. 13. In one embodiment, the protrusion 113 includes a protrusion top surface 1131 facing away from the blade 111, and a protrusion side surface 1132 connected to the blade circumferential side surface 1111, wherein the protrusion side surface 1132 is connected to the protrusion top surface 1131 by a second chamfer 1134.
