Abstract

A hinge device of a steam oven door comprises a mount provided with a slide slot thereon, which is installed on an inner lateral wall of an oven case. A roller wheel is slidably mounted in the slide slot. One side of the mount is pivotally installed with a rotary beam provided with a spring; the free end of the spring is fixed on the lateral wall of the oven case. The opposite side of the mount is provided with a push beam with one end pivotally connected to the roller wheel and the rotary beam. The rotary beam is pivotally connected to a link beam with second end pivotally connected to a curved element, whose one end is in turn pivotally connected to the mount. The other end of the curved element is pivotally connected to a transmission beam.
