A touch control device for an electric fireplace includes a touch control panel, a face shell, a sensing electrode, an LED light, and a light guide cover. The face shell is installed on the touch control panel. An accommodation space is defined between the face shell and the touch control panel. The inner surface of the face shell is provided with a silkscreen layer for showing button information. When the LED light is turned on, the light guide cover blocks the LED light from shining directly to form even light. The even light projects on the silkscreen layer, such that the button pattern can be seen clearly from the front of the face shell. When the LED light on the touch control panel is turned off, the button pattern will disappear from the front of the face shell to achieve the purpose of hidden buttons. |
