[0015] The utility model will be further described in combination with the description and specific implementation of the drawings:

[0016] As Figs. 1 to 3 The embodiment of the utility model provides a panel assembly for a pressure cooker, which comprises a display surface cover, a light-transmitting surface shell 1 and a circuit board 2 connected in sequence, the display surface cover comprises a light-transmitting cover 3 and a one-way perspective film arranged on the light-transmitting cover 3, a plurality of light-transmitting holes 4 are arranged on one side of the light-transmitting surface shell 1 in a spaced-apart manner, the light-transmitting cover 3 covers the light-transmitting surface shell 1 and covers the plurality of light-transmitting holes 4, and a plurality of LED lamps 5 are arranged on the circuit board 2 in correspondence with the plurality of light-transmitting holes 4. Further, a light-transmitting film 6 is adhered to the light-transmitting surface shell 1, a plurality of patterns are arranged on the light-transmitting film 6 in correspondence with the plurality of light-transmitting holes 4, and the plurality of patterns are all different.

[0017] Specifically, the one-way perspective film is a relatively mature prior art, and its structure principle is not described in detail here. When the outer side of the display cover is brighter than the inner side, the outer side of the display cover cannot see the scene of the inner side. When the inner side of the display cover is brighter than the outer side, the outer side can see the scene of the inner side, and the clarity degree depends on the brightness of the inner and outer sides.

[0018] The display cover is covered on the light-transmitting shell to protect the light-transmitting pattern film adhered on the light-transmitting shell. The one-way perspective film is arranged on the display cover. When the light-transmitting shell is not lighted, the one-way perspective film covers the patterns on the light-transmitting shell. When a pattern of the light-transmitting shell is lighted, the pattern can directly pass through the one-way perspective film and be exposed to the outer side of the display cover, thereby facilitating the user to intuitively know the working state of the electric pressure cooker without searching for the lighted pattern in the numerous patterns to determine the working state.

[0019] Further, the light-transmitting shell 1 is concave along the circumferential edge profile on one side, and the light-transmitting cover 3 is convex along the circumferential edge profile on one side, and the convex flange 8 is embedded with the concave groove 7. In this way, the display cover is sealed and covered on the light-transmitting shell, effectively avoiding the light leakage problem of the side of the display cover.

[0020] Further, the light-transmitting shell 1 is concave on one side, and the circuit board 2 is fixed and arranged in the concave cavity 9. In this way, the light-transmitting shell is closely installed on the outer wall of the electric pressure cooker.

[0021] Further, the light-transmitting cover 3 is provided with a plurality of buckle members 10 on one side, and the light-transmitting shell 1 is provided with a plurality of clamping grooves 11 corresponding to the buckle members 10. In this way, the display cover and the light-transmitting shell are connected by buckling.

[0022] Further, the light-transmitting shell 1 is provided with a plurality of annular light guide walls 12 on one side, and the annular light guide walls 12 and the light-transmitting holes 4 are arranged one by one. The light-transmitting holes 4 are located in the inner ring area of the annular light guide wall 12, and one end surface of the annular light guide wall 12 is a plane and closely abuts to one side of the circuit board 2. In this way, the annular light guide wall realizes light guide for the corresponding LED lamp, and effectively avoids the light leakage problem.

[0023] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principle of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
