Okay, the user wants me to translate "cooker hood" into Traditional Chinese. Let me check what that term refers to. A cooker hood is typically a kitchen appliance used to vent smoke and odors. In Chinese, the common term for this is 抽油烟机. Let me confirm if that's the correct translation. Yes, 抽油烟机 is the standard term used in Taiwan and Hong Kong for range hoods. Since the user specified Traditional Chinese, I should use that term. Also, the user mentioned that if the content is already in Traditional Chinese, I should leave it unchanged. But in this case, the input is in English, so I need to translate it. The response should be just the translation without any explanations. Alright, the answer should be 抽油烟机.
