[0002] As people's pursuit of delicious food continues to improve, cooking equipment has become an important home appliance product for enhancing quality of life, showcasing personal taste, and pursuing a healthy lifestyle. Existing cooking equipment includes a cabinet and a door assembly that is hinged to the cabinet. On the other side of the door assembly, a door hook engages with a limiting part of the cabinet to restrict the opening or closing of the door assembly relative to the cabinet.

[0003] Because the door can make a loud noise and affect the user experience due to the force and inertia of the door hook when opening and closing; in addition, if the door is opened by children or others, there is a risk of burns from the heated food inside the appliance. To address this, Chinese Patent Application No. CN202210273313.9 discloses a door structure and a cooking appliance. The door structure includes a door body, a latching member, and a switch. The door body is openable and closable and connected to the appliance body. The appliance body includes a limiting part. The latching member is provided on the door body. The switch can drive the latching member to move relative to the door body between a first position and a second position. The switch is formed by the portion of the latching member protruding from the outside of the door body. When the latching member is in the first position, it is latched onto the limiting part. When the latching member is in the second position, it disengages from the limiting part. Although this solution can effectively reduce noise when opening and closing the door, the opening and closing mechanism is subjected to force, and the force-bearing area is small, making it easy to be damaged. In addition, opening the door requires pushing the switch first and then pulling the door handle. The two steps involve different objects, making opening the door not only cumbersome but also reducing the opening speed.

[0040] In the existing technology, when the door component 10 is opened, the switching element is subjected to force, the force-bearing area is small, and it is easy to be damaged. In addition, when opening the door, the switch must be pushed first and then the door handle must be pulled. The two steps involve different objects, which not only makes opening the door cumbersome, but also reduces the opening speed.

[0041] To solve the above technical problems, such as Figures 1-11 As shown, a door assembly 10 is proposed for a cooking device 100, which includes, but is not limited to, kitchen appliances such as microwave ovens, ovens, steam ovens, and integrated appliances.

[0042] like Figure 1 and Figure 2 As shown, the cooking device 100 includes a housing 20, and a door assembly 10 is rotatably connected to the housing 20. The door assembly 10 is openable and closable on the housing 20. The housing 20 can be understood as the main cooking component of the cooking device 100 used for cooking. The housing 20 has a cooking cavity with an opening, facilitating the placement and removal of items. The door assembly 10 can be installed on the opening side of the housing 20, and the door assembly 10 can rotate relative to the housing 20 to open or close the housing 20.

[0043] like Figure 4 and Figure 5 As shown, the housing 20 includes a limiting part 91.

[0044] like Figures 1-4 As shown, the door assembly 10 includes:

[0045] Door 1 can be installed on the opening side of the housing 20 of the cooking appliance 100. Door 1 can be rotatably connected to the housing 20 by hinges or other means, so that door 1 can be opened or closed relative to the housing 20. In some other embodiments, door 1 can also be slidably disposed relative to the housing 20 to achieve opening and closing. For example, the housing 20 is provided with a slide rail, and door 1 opens and closes the housing 20 by sliding on the slide rail.

[0046] The shape of the door 1 can be adapted to the opening shape of the cabinet 20, thereby improving the airtightness of the cabinet 20 when the door 1 is closed relative to the cabinet 20, allowing the cooking device 100 to cook food better.
