When cooking food using a heating device such as a gas range, microwave oven, or rice cooker, not only the indoor temperature, especially the temperature of the kitchen, is increased, but also the humidity increases due to the steam generated during cooking, making cooking of food more difficult. There is a problem.

Accordingly, it is an object of the present invention to provide a kitchen air conditioner to enhance the user's convenience by providing cold air when cooking or eating in a kitchen.
