To prevent dew condensation on a back surface of a panel without requiring packing or by reducing use of the packing.
The panel 6 includes keys 18-23 (operating parts) operated by a user and a transparent part. A control device 7 includes switches operated by the operating parts and a liquid crystal display 62 (a display part) for displaying transparently through the transparent part. Labyrinth seal structure 104 is formed between the panel 6 and the control device 7 so as to surround at least the transparent part. Thereby, steam is prevented from entering the back surface of the panel 6, specifically a back surface of the transparent part so that dew condensation on these parts are prevented without requiring the packing or by reducing the use of the packing.
