[0002] With the development of science and technology, smart home appliances such as ovens are becoming more and more popular. At the same time, with the improvement of living standards, people's performance requirements for smart home appliances such as ovens are also getting higher and higher. At present, in smart home appliances such as ovens, the opening and closing of the appliance doors are mainly achieved through manual operation. Manual operation uses a lock or the like to open or close the door, but manual operation not only prolongs the operation time and affects the user experience, but may also cause burns to the user when handling high-temperature food. The Chinese patent document with announcement number CN214964716U discloses a household electric oven door opening mechanism. The door opening mechanism uses a curved glass door, guide rails, rollers, handles and other structures to realize the opening and closing of the oven door. The door is easy to open and is more convenient and safer than the traditional oven pull-down door opening. However, the door opening mechanism has not yet fully realized the automatic door opening function, resulting in a poor user experience. Utility Model Content

The locking lever 4 is hinged to the locking bracket 3 via a self-tapping screw 5. The locking lever 4 is swingable relative to the locking bracket 3.

[0043] The second side 1602 of the door body 16 is provided with two door hooks 2, which are arranged vertically and cooperate with the interlocking lever 4 to open or close the door body 16;

[0044] The transmission module includes a motor bracket 14, a motor 15, a lever 9, and an eccentric wheel 12; the motor bracket 14 is arranged on the third side 1703 of the box body, the motor 15 is arranged on one side of the motor bracket 14, and the eccentric wheel 12 is arranged on the output rotating shaft of the motor 15 through a locking screw 11; the lever 9 is hinged to the motor bracket 14 through a lever fixing column 10, the first lever arm 901 of the lever 9 is located in the groove below the eccentric wheel 12, and the second lever arm 902 of the lever 9 is located below the trigger end 401 of the chain lever 4.

[0045] The second lever arm 902 of the lever 9 drives the chain lever 4 to swing relative to the chain bracket 3 by abutting or disengaging from the trigger end 401 of the chain lever 4. When the chain lever 4 swings to the first position, the action end 402 of the chain lever 4 disengages from the door hook 2. When the chain lever 4 swings to the second position, the door hook 2 is pressed above the action end 402 of the chain lever 4.

[0046] The interlocking bracket 3 is also provided with a first micro switch 6, a second micro switch 7 and a third micro switch 8; the first micro switch 6 is used to sense the position of the upper door hook 2; the second micro switch 7 and the third micro switch 8 are used to sense the swing position of the interlocking lever 4.
