Apparatus for controlling door opening speed of cooking appliance with automatic opening structure
The present invention provides a lever (300) for opening a door (720) by pushing and releasing a latch (200) which is retracted into and locked with a latch holder (10) in the opening direction of the door (720). The lever (300) is automatically controlled by a controller (90). According to an automatic door opening mechanism, when power is supplied to a cooking appliance or when a user turns on the cooking appliance, the lever (300), a pusher (500), and a pusher driving part (600) are controlled to be aligned in a predetermined position. After the user inputs a door opening command, in order to proceed with a door opening operation, the user can check whether each component involved in the automatic door opening operation has an abnormality, through a change of a return stop switch and a change of an open detection switch generated during one rotation of a motor. The door, which is opened at an initial opening angle due to the releasing of the latch, is automatically opened in a pull-down manner by its own weight, and a damper intervenes at a predetermined opening angle so that the door can descendingly open at a controlled speed.
