Why not?I wouldn't call a microwave oven or a charcoal grill a cooker, though they're both appliances used to cook food.
I associate a microwave with heating food rather than cooking it. A charcoal grill is a bit limited to be a cooker. I wouldn't call a couple of electric rings a cooker either if there was not oven or grill. I'd use the definition in 5jj's post.Why not?
A cooker is a large metal device for cooking food using gas or electricity. A cooker usually consists of a grill, an oven, and some gas or electric rings.

...a gas cooker.
We also use the word 'cooker in such compounds as pressure cooker, rice cooker, and slow cooker as barque noted.
Microwaves, charcoal grills, electric toasters and campfires are not cookers.
Are microwaves, charcoal grills and electric toasters considered cookers?
I prefer the knowledge of the teachers at UE and the authority of the dictionaries at www.onelook.com.I posed the question to ChatGPT
So, while each of these appliances has its own specific purpose and method for cooking, they can all be considered types of cookers.
You could be right.It seems to me that the proper question that the OP meant to ask is 'What do you call this?'


In this case, the dictionaries merely give a general definition of a cooker, which is an appliance used for cooking. They do not specifically exclude the microwave oven as a cooker. The categorisation is rather subjective, so I think it is just an opinion when someone says it's not. It is like saying "something is true because I say so".I prefer the knowledge of the teachers at UE and the authority of the dictionaries at www.onelook.com.
