Oven

[Technical Field]

0001Embodiments of the present disclosure relate to an oven including a display module.

[Background Art]

0002Generally, ovens are devices including cooking chambers, heaters configured to heat the cooking chambers, and circulating fans configured to circulate heat generated by the heaters in the cooking chambers and cook food.

0003The ovens may be divided into electric ovens, gas ovens, and electronic ovens according to heating sources. An electric oven uses an electric heater as a heating source, and a gas oven and a microwave oven use heat generated using gas and frictional heat due to a high frequency as heating sources, respectively.

0004An oven may include a display module provided to display various pieces of operational information and receive operational commands from a user.

0005The display module may be formed at a front surface of the oven such that a user is able to easily approach the display module. Generally, the display module may be provided to face in a forward direction of the oven. In this case, it is sometimes difficult for the user to see the information displayed on the display module due to a difference in a viewing angle. Accordingly, the user has to accept the inconvenience of changing his or her posture to match his or her eye level with the display module.
