Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of oven, especially oven double -open door structure and oven. BACKGROUND
[0002] The door of the existing oven is generally a single door oven, which is opened or closed by a downward opening or a side opening. The single door structure of the oven leads to a large movement amplitude of the door when opening and closing, which occupies a large operation space and is not suitable for use in a small space.
[0003] In order to solve the problem of small space, the market has launched a double door oven, however, the double door oven needs to be opened and closed with both hands, which is extremely inconvenient when the user needs to operate with one hand. In order to solve the above-mentioned problem of needing to operate with both hands, some manufacturers set a driving part inside the double door structure, and a guide device is arranged in the middle of the driving part. The driving part and the guide device are matched with each other, so that the double door can be opened and closed at the same time. However, the driving part and the guide device have a complex structure, high manufacturing cost and poor smoothness, which increases the installation difficulty of the oven and affects the working stability of the oven to some extent.
