[0002] In related technologies, such as Figure 13 As shown, the handle 10' of the door assembly 1' of cooking appliances is usually external, which takes up space, makes the appearance of the cooking appliance less simple and beautiful, and may also cause damage to the door assembly due to collisions or other reasons during use. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this utility model provides a door assembly.

[0005] A second aspect of this utility model also provides a cooking utensil.

[0006] In view of the above, the first aspect of this utility model provides a door assembly for a cooking appliance. The cooking appliance includes a housing with an opening. The door assembly includes: a frame located on the side of the housing with the opening and movably connected to the housing so that the door assembly can open or close the opening; the frame has a relief groove recessed from the side of the frame away from the opening toward the side of the frame closer to the opening; and a door panel located on the side of the frame away from the opening. The door panel covers a portion of the relief groove, leaving the other portion of the relief groove exposed on the door panel. The portion of the door panel covering the relief groove forms a handle.

[0007] The door assembly provided by this utility model includes a frame and a door panel. The door panel is located on the side of the frame opposite to the opening. The frame is movably connected to the cooking appliance's housing. The door assembly is used to open or close the opening of the housing. The frame has a recessed groove located on the side of the frame opposite to the opening and recessed towards the opening. This allows the door panel to partially cover the recessed groove, while the other part of the groove remains exposed. The portion of the door panel covering the recessed groove forms a handle. When a user needs to pull the door assembly to open the housing, the user inserts their hand from the exposed portion of the recessed groove into the recessed groove and pulls on the portion of the door panel covering the recessed groove, thus using this portion as a handle to open the door assembly. The door assembly proposed in this application does not have a protruding handle from the door panel, achieving a concealed handle design. This reduces the space occupied by the door assembly when the cooking appliance is placed and also prevents damage to the handle due to accidental collisions.

[0008] In some embodiments, the clearance groove may optionally include a shielding area and an open area, the clearance groove being exposed on the door panel through the open area and the handle portion being shielded in the shielding area; wherein, the open area is located at the top of the shielding area along the height direction of the housing, or the open area is located at the bottom of the shielding area along the height direction.

[0009] In this embodiment, the clearance groove includes a concealed area and an open area. The door panel conceals the handle in the concealed area, and the clearance groove is exposed through the open area. The open area can be located at the top or bottom of the concealed area; that is, the handle can be located at the top or bottom of the open area, achieving versatility in handle placement. When the handle is located at the top of the open area, the user inserts the handle into the clearance groove from the bottom and pulls it; when the handle is located at the bottom of the open area, the user inserts the handle into the clearance groove from the top and pulls it.

[0091] like Figure 10 and Figure 11 As shown, in some embodiments, the microwave generator 40 is optionally located on the side of the first housing 22 away from the opening 20.

[0092] In this embodiment, the microwave generator 40 is located on the side of the first box 22 away from the opening 20, so as to avoid the microwave generator 40 occupying space in the length and height directions of the first box 22, and also to facilitate the user to take out and put in the food in the first box 22.

[0093] like Figure 10 As shown, in some embodiments, the cooking appliance may optionally include a fan assembly 5, wherein when the door assembly 1 includes an air inlet 1072, an air outlet 1074 and a heat dissipation channel 14, the fan assembly 5 is connected to the heat dissipation channel 14 through the air inlet 1072 or the air outlet 1074.

[0094] In this embodiment, the cooking appliance also includes a fan assembly 5. When the door assembly 1 is provided with an air inlet 1072, an air outlet 1074 and a heat dissipation channel 14, the fan assembly 5 is connected to the heat dissipation channel 14 through the air outlet 1074 to achieve passive heat dissipation in the heat dissipation channel 14, thereby improving the heat dissipation effect of the door assembly 1 and ensuring that the user is not affected by the temperature when pulling the door panel 12.

[0095] It is understandable that the fan assembly 5 is connected to the air outlet 1074. When the fan assembly 5 is turned on, air enters the heat dissipation channel 14 through the air inlet 1072 under the action of negative pressure, and then is discharged from the cooking appliance through the air outlet 1074 via the fan assembly 5.

[0096] Optionally, such as Figure 12As shown, the housing 2 is also provided with an air inlet 26 and an air outlet 28. The air outlet 1074 is connected to the air inlet 26. A suction force is formed at the air inlet 1072 at the bottom, which causes the airflow to enter the heat dissipation channel 14 through the air inlet 1072. A negative pressure is formed at the air outlet 1074, and part of the air in the heat dissipation channel 14 is discharged from the air outlet 1074 at the top and enters the air inlet 26. Under the action of the fan assembly 5, it is discharged from the air outlet 28.

[0097] Optionally, there are two air vents 1074. One air vent 1074 is located on the top of the outer frame 107 near the side of the housing 2 and is connected to the air inlet 26. The other air vent 1074 is located on the top of the outer frame 107 and is opposite to the air outlet 28. When the fan assembly 5 is turned on, the airflow at the other air vent 1074 flows out under the action of negative pressure.

[0098] Optionally, the door structure corresponding to the second enclosure 24 (the structure can be the same as the door component 1 corresponding to the first enclosure 22, or it can be another door structure) is also provided with a heat dissipation duct. The heat dissipation duct of the second enclosure 24 is connected to the heat dissipation channel 14 of the door component 1 corresponding to the first enclosure 22, so that when the fan assembly 5 is turned on, the heat dissipation of the door structure of the second enclosure 24 and the door component 1 of the first enclosure 22 can be achieved at the same time.

[0099] Optionally, when the fan assembly 5 is open, the airflow enters the door structure corresponding to the second housing 24 from the outside, then enters the heat dissipation duct of the door assembly 1 of the first housing 22 from the top of the door structure corresponding to the second housing 24, and is then discharged through the air outlet 1074.

[0100] Optionally, the second enclosure 24 is connected to the fan assembly 5 via a smoke exhaust pipe. When the temperature inside the second enclosure 24 reaches a set value, the fan assembly 5 is turned on to exhaust smoke from the second enclosure 24.

[0101] like Figure 6 , Figure 10 and Figure 11 As shown, in some embodiments, the cooking appliance may optionally include a stove assembly 3, located on top of the housing 2.

[0102] In this embodiment, the cooking appliance also includes a stove assembly 3, which is disposed on the top of the housing 2, so that the cooking appliance integrates a stove and an oven, thereby improving the practicality of the cooking appliance.

[0103] In some embodiments, the stove assembly 3 may optionally include: a panel 30 disposed on the top of the housing 2; and an electromagnetic heating element disposed on the bottom of the panel 30, wherein when the electromagnetic heating element is energized, the electromagnetic heating element can heat the cookware on the top of the panel 30.

[0104] In this embodiment, the stove assembly 3 includes a panel 30 and an electromagnetic heating unit. When the electromagnetic heating unit is energized, the magnetic field generated by the electromagnetic heating unit can heat up the pot above the panel 30, thereby achieving electromagnetic heating. Electromagnetic heating has high safety performance, is easy to use, and improves the convenience of cooking.

[0105] According to some embodiments of this application, this application proposes a stationary microwave oven door system (e.g., door assembly 1). Door assembly 1 adopts a handle-less design, consisting of an oven door glass (e.g., door panel 12) and a plastic outer frame (e.g., frame 10). The user can open and close door assembly 1 simply by gently pulling the upper right corner of the oven door glass. The plastic outer frame is designed with a handle avoidance area (e.g., avoidance groove 102).

[0106] The plastic outer frame is designed with air inlet 1072 and air outlet 1074 for heat dissipation. The cold air blown out from the large oven (e.g., the second chamber 24) passes through the heat dissipation duct of the plastic outer frame to dissipate heat to the entire door assembly 1, so that the user will not be affected by the temperature when opening the oven door glass.

[0107] The door assembly 1 consists of four parts, including a hardware bracket 109 (e.g., bracket 109) for connecting the main body of the standing microwave oven to the door assembly 1; a microwave door (e.g., microwave shielding plate 108) for preventing microwave leakage; a plastic outer frame (e.g., outer frame 107) for appearance and component connection; and a door glass (e.g., door panel 12) for appearance and door handle. The assembly of the door assembly 1 is simpler and less expensive.

[0108] The door assembly 1 proposed in this application adopts a handle-less design, with the handle cleverly hidden on the right side of the door assembly 1. This avoids damage to the handle due to accidental collisions, simplifies the microwave oven door system, reduces the number of parts, and optimizes manufacturing and costs. Furthermore, the concealed handle design makes the door assembly 1 more aesthetically pleasing and avoids potential collision damage caused by an external handle, thus extending the service life of the door assembly 1.

[0109] Alternatively, the microwave system (e.g., microwave generator 40) can also be placed on the top, bottom, or both sides of the first housing 22 to achieve microwave functionality.
