Thirdly, a heating chamber for a fish fryer or the like is provided on either the left or right side of the lower heating unit, and an intake port for ventilation of the cooling fan is provided on the opposite side of the decorative plate from the position corresponding to the heating chamber. As a result, the distance between the heating chamber, which is the source of heat, and the plaque can be increased, and conductive heat and radiant heat from the heating chamber are less likely to increase the temperature of the cooling air sucked in through the intake port of the plaque, resulting in a cooling effect. A heating chamber for a fish fryer or the like can be provided without deteriorating performance.

Fourth, a heating chamber for a fish fryer or the like is provided on either the left or right side of the lower heating unit, and an air intake is installed between the lower heating unit and the upper heating unit to guide the cooling air from the air inlet of the plaque to the cooling fan. Because the guide was installed on the lower heating unit on the opposite side from the position corresponding to the heating chamber,
The cooling air that flows in from the air inlet of the plaque is guided by the air intake guide to the cooling fan of the upper heating unit over the shortest distance, and is also prevented from being affected by heat from the heating chamber at the bottom, which further improves cooling performance for internal components. This makes it possible to create a built-in cooking device with a heating chamber that is highly reliable.
