Description

Technical Field

[0001] The utility model relates to the field of cooking devices, in particular to a door body and a steaming and baking all-in-one machine for cooking devices. Background Art

[0002] The door handles of existing cooking devices (e.g., steamers, ovens, steam-and-bake all-in-one machines, etc.) are generally protruding on the front of the door body. Due to the limited kitchen space, the protruding handles will take up extra kitchen space. In addition, the protruding handles are easy to bump into the user. Since the handles are generally made of metal and have edges and corners, the user will suffer certain trauma after bumping into them, causing safety hazards. At the same time, heavy objects hitting the handles are also the main reason for the shattering of the door glass. For example, the Chinese utility model patent with patent number ZL202221406462.X (authorization announcement number CN217390520U), the Chinese utility model patent with patent number ZL202221161561.6 (authorization announcement number CN217338306U), etc.

[0003] In addition, the existing handle is generally set on the front of the door body by bonding. For example, the Chinese utility model patent with patent number ZL202020694023.8 (authorization announcement number CN212326192U) discloses a door suitable for household ovens, steam ovens and microwave ovens, one side of the handle is provided with a clamping groove, the clamping groove is clamped on one side of the door panel, and an adhesive layer is provided between the inner wall of the clamping groove and the door panel to fix the handle on the door panel. In this way, the force exerted on the handle when opening and closing the door will be transmitted to the connection between the handle and the door body, which will cause the handle to loosen from the door body after long-term use, affecting the stability of the handle installation, and in severe cases, causing the handle to fall off.
