Description

Technical Field

[0001] The utility model relates to the technical field of induction cookers, in particular to a display control device for an induction cooker. Background Art

[0002] An induction cooker is an electrical cooking appliance made based on the principle of electromagnetic induction heating. It mainly uses a coil disk to generate a low-frequency (20-25KHZ) alternating magnetic field under the action of a control circuit, which generates a large amount of dense eddy current through the magnetic (iron) pot, and converts the induced current into heat to heat food.

[0003] The front of the induction cooker is usually equipped with a display control device for displaying parameters such as temperature and time and for touch control. The display control device includes a glass panel and a light board located below the glass panel. Some indicator lights are set on the light board, which, together with the printed text or pattern on the glass panel, makes the user's touch control operation more intuitive.

[0004] Conventional light panels, such as Figure 1 and Figure 2 As shown, after the lamp body 411 is powered on, the light generated by the lamp body diverges toward the glass panel. When the user looks down from above, he sees a larger bright area through the glass panel 20. The focusing effect is poor and the clarity is insufficient, which affects the user's touch control operation judgment.

[0005] In order to solve the above problems, some manufacturers have designed some grid-shaped lampshades, such as an induction cooker disclosed in Chinese patent publication No. CN105371316A, which includes a shell, a lamp board and a heating element arranged in the shell; the shell includes a base and a panel sealing the opening of the base; the panel includes a heating panel made of microcrystalline material and an operating panel made of tempered glass; the operating panel is located on one side of the heating panel; the lamp board is installed on the base corresponding to the operating panel; the lamp board includes a lamp board body and a plurality of lamp bodies arranged on the lamp board body; a light-transmitting pattern is provided on the operating panel corresponding to each lamp body; the induction cooker also includes a lampshade covering the lamp board, and the lampshade is arranged close to the operating panel; a lamp body accommodating hole for accommodating the lamp body is provided on the lampshade corresponding to each lamp body, so that there will be no cross-light phenomenon on the panel, thereby enhancing the clarity of the light emitted by the lamp body displayed on the operating panel.

[0006] Although the above-mentioned lampshade can improve the display clarity of the light on the operation panel, the lampshade is made of a larger material and a lamp body accommodating hole is opened on the lampshade to accommodate the lamp body. It is suitable for structures with densely distributed lamp bodies. For lamp panels with relatively dispersed lamp bodies, if this lampshade is used, it will seriously affect the normal arrangement of other electronic components.

[0007] Therefore, the prior art still needs to be improved and developed. Utility Model Content

[0008] In view of the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a display control device for an induction cooker to solve the problem that the lampshade of the prior art occupies a large volume and affects the arrangement of other electronic components on the lamp board.
