However, this prior art still has structural shortcomings; its heating plate is fixed to the bottom of the body, its heating method is limited, and its heating effect and efficiency are not good enough.

[0004] Therefore, there is still room for improvement and development in existing technologies. Technical solutions

[0005] To address the problems of existing technologies, this utility model provides a multi-functional cookware that can perform multi-functional food processing and can switch between different heating modes of the heating device according to different functions, thereby improving the heating effect and efficiency.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A multi-functional cookware includes a main unit with an inner cavity. An air-roasting accessory or a grilling / steaming accessory is detachably installed within the inner cavity. A heating element is rotatably mounted within the inner cavity and has two modes: air-roasting and grilling. In air-roasting mode, the air-roasting accessory is installed in the inner cavity, and the heating element is located on its side. In grilling mode, the grilling / steaming accessory is installed in the inner cavity, and the heating element is located at its bottom. A linkage rotating mechanism is connected to the heating element. When the grilling / steaming accessory is installed in the inner cavity, it drives the linkage rotating mechanism to switch the heating element from air-roasting to grilling mode. This configuration allows the heating element to perform multiple food processing functions, and the switching between different heating modes improves heating effect and efficiency, enriching the cookware's applicability and usage scenarios. When the grilling / steaming / cooking accessories are placed in the inner cavity, the grilling / steaming / cooking accessories drive the linkage rotation mechanism to switch the heating device from air-baking mode to grilling / steaming mode, which is very convenient.

[0008] According to the above scheme, the heating device includes heating tube assembly one and heating tube assembly two; in the air-baking heating mode, the air-baking accessory is assembled in the inner cavity, and heating tube assembly one and heating tube assembly two are vertically located on both sides of the air-baking accessory; in the frying and grilling heating mode, the frying, grilling and steaming accessory is assembled in the inner cavity, and heating tube assembly one and heating tube assembly two are horizontally located at the bottom of the frying, grilling and steaming accessory, and heating tube assembly one and heating tube assembly two cooperate to divide the inner cavity into upper and lower cavities. With this configuration, in air-baking mode, the air-baking accessories are assembled in the inner cavity, with heating element assembly one and heating element assembly two vertically positioned on both sides of the air-baking accessories. This allows for even and rapid heating of both sides of the air-baking accessories, enabling air-baking processing of food with better heating effect and higher work efficiency. In grilling mode, the grilling / steaming accessories are assembled in the inner cavity, with heating element assembly one and heating element assembly two horizontally positioned at the bottom of the grilling / steaming accessories. This allows for even and rapid heating of the bottom surface of the grilling / steaming accessories, enabling grilling / steaming processing of food. In grilling mode, heating element assembly one and heating element assembly two work together to divide the inner cavity into upper and lower chambers. The upper chamber forms a separately heated chamber, which helps to limit heat loss. At the same time, the chamber volume is small, resulting in higher heating efficiency.

[0009] According to the above scheme, the linkage rotation mechanism includes a push rod, a rotating plate, a connecting shaft, a connecting plate, a tension spring, and a guide rod. The guide rod is vertically installed inside the main unit. Rotating plates are symmetrically arranged on both sides of the guide rod. The two rotating plates are respectively hinged to the main unit through the connecting shaft. The push rod is slidably arranged on the guide rod. A part of the push rod passes through the inner wall of the inner cavity and extends into the inner cavity. The two ends of the push rod are respectively arranged corresponding to the first ends of the two rotating plates. The second ends of the two rotating plates are respectively connected to the connecting plates. The two connecting plates are respectively connected to the heating tube assembly one and the heating tube assembly two. Tension springs are fixed between the two rotating plates and the main unit. With this configuration, when the grilling / steaming / cooking accessory is placed into the inner cavity, it presses against the top rod, causing the top rod to move downwards along the guide rod. The top rod then drives the rotating plate to rotate downwards, which in turn drives the connecting plate to rotate upwards. The connecting plate, through the downward rotation of the rotating plate, drives heating element assembly one and heating element assembly two to rotate, thus ensuring that heating element assembly one and heating element assembly two come into contact with the grilling / steaming / cooking accessory, which facilitates heating the accessory by the heating element assembly one and heating element assembly two. When the grilling / steaming / cooking accessory is removed from the inner cavity, the linkage rotation mechanism resets under the action of the tension spring, controlling the switching of heating element assembly one and heating element assembly two from the grilling / steaming heating mode to the air-baking heating mode.

[0010] According to the above scheme, pulleys are installed at both ends of the push rod, and the pulleys are correspondingly arranged at the first end of the rotating plate. This arrangement reduces the transmission resistance when the push rod drives the rotating plate.

[0011] According to the above scheme, a second pulley is installed at the second end of the rotating plate, and a groove is formed inside the connecting plate, with the second pulley slidably disposed within the groove. This arrangement reduces transmission resistance when the rotating plate drives the connecting plate to move.

[0012] According to the above scheme, a guide hole is formed on the inner wall of the cavity, and a part of the push rod extends into the inner cavity through the guide hole, with the push rod slidingly disposed with the guide hole. With this configuration, when the grilling / steaming / cooking accessory is placed into the inner cavity, the accessory contacts the push rod and drives the push rod to slide within the guide hole.

[0013] According to the above scheme, the heating tube assembly one and heating tube assembly two have the same structure, both including a reflector plate and a heating tube. The heating tube is fixed to the reflector plate, and fixing plates are respectively fitted at both ends of the heating tube. The fixing plates are fixedly connected to the inner wall of the inner cavity, and the heating tube can rotate relative to the fixing plates. One end of the heating tube extends out of the inner cavity and is fixedly connected to a connecting plate. This arrangement allows the heat generated by the heating tube to heat the food, and the reflector plate radiates the heat generated by the heating tube to the surface of the food, which helps to improve the efficiency of heating the food.

[0014] According to the above scheme, a convection component is also included. The convection component comprises a shaded-pole motor and a fan blade. The shaded-pole motor is fixed to the outer wall of the inner cavity, and the fan blade is fixed to the output end of the shaded-pole motor, with the fan blade corresponding to the inner cavity. This configuration provides uniform hot air through the convection component, which is beneficial for the air-frying performance of food inside the inner cavity and optimizes the heating effect for roasting meat.

[0015] According to the above solution, it also includes a door body, which is rotatably connected to the main unit and used to open or close the opening of the inner cavity. The main unit is equipped with an opening button that cooperates with the door body, the door body is equipped with an exhaust vent communicating with the inner cavity, the inner wall of the door body is equipped with a sealing ring, the outer wall of the door body is equipped with a control panel, and the main unit is equipped with a viewing window. With this configuration, when the door body closes the opening of the inner cavity, the sealing ring prevents heat loss during food processing; the door body can be easily opened by pressing the opening button, making operation convenient; the exhaust vent is used to release steam generated during the operation of the grilling, baking, steaming, and boiling accessories; and during baking, the oven light can be turned on so that the user can more clearly see the processing changes of the food through the viewing window.

[0016] According to the above design, a detachable slag collection tray is installed on the main unit, extending into the inner cavity and located at the bottom of the inner cavity. This design facilitates the cleaning of food processing residues later.

[0017] According to the above solution, the grilling, frying, steaming, and cooking accessories include a grilling pan and a steaming rack detachably installed inside the grilling pan. The grilling pan has ribs that cooperate with the top rod. With this configuration, when the grilling pan is placed in the inner cavity, the ribs on the grilling pan press against the top rod and drive the top rod downwards along the guide rod. The inner wall of the grilling pan has a limiting step for limiting and supporting the steaming rack. When the steaming rack is not installed, the grilling pan can be used for grilling food or cooking hot pot; when the steaming rack is installed, it can be used for steaming food.

[0018] According to the above scheme, the air-frying accessories include a frying basket, a rotating basket, a grill rack, or a rotisserie fork. The main unit is equipped with a drive motor for driving the rotating basket, grill rack, or rotisserie fork to rotate. With this configuration, when the air-frying accessory is a frying basket, it can be used with a heating device and convection components to achieve air-frying performance for food; when the air-frying accessory is a rotating basket, grill rack, or rotisserie fork, it can be used for grilling meat. Each end of the rotating basket, grill rack, or rotisserie fork has a rotating shaft, and the output end of the drive motor has a bushing that connects to the rotating shaft. The drive motor drives the rotating basket, grill rack, or rotisserie fork to rotate, resulting in more even heating of the food. Beneficial effects

In the frying / steaming heating mode, the frying / steaming accessory is assembled in the inner cavity 2, and the heating device 3 is located at the bottom of the frying / steaming accessory. A linkage rotating mechanism is drivenly connected to the heating device 3. When the frying / steaming accessory is assembled in the inner cavity 2, the frying / steaming accessory drives the linkage rotating mechanism to switch the heating device 3 from the air-baking heating mode to the frying / steaming heating mode. This design allows the heating element 3 to operate in both air-baking and grilling modes, enabling multi-functional food processing. The ability to switch between different heating modes based on the desired function improves heating effect and efficiency, thus expanding the cookware's applicability and usage scenarios. Specifically, when the grilling / steaming / cooking accessories are placed in the inner cavity 2, the accessories drive a rotating mechanism to switch the heating element 3 from air-baking to grilling / cooking mode, making the switching process very convenient.

[0044] Furthermore, the heating device 3 includes a heating tube assembly 31 and a heating tube assembly 32; in the air-baking heating mode, the air-baking accessory is assembled in the inner cavity 2, and the heating tube assembly 31 and the heating tube assembly 32 are vertically located on both sides of the air-baking accessory; in the frying and grilling heating mode, the frying and grilling / steaming accessory is assembled in the inner cavity 2, and the heating tube assembly 31 and the heating tube assembly 32 are horizontally located at the bottom of the frying and grilling / steaming accessory, and the heating tube assembly 31 and the heating tube assembly 32 cooperate to divide the inner cavity 2 into upper and lower cavities. With this configuration, in air-baking mode, the air-baking accessories are assembled in the inner cavity 2, with heating element assembly 31 and heating element assembly 32 vertically positioned on both sides of the air-baking accessories. This allows for uniform and rapid heating of both sides of the air-baking accessories, enabling air-baking processing of food with better heating effect and higher working efficiency. In grilling mode, the grilling / steaming accessories are assembled in the inner cavity 2, with heating element assembly 31 and heating element assembly 32 horizontally positioned at the bottom of the grilling / steaming accessories. This allows for uniform and rapid heating of the bottom surface of the grilling / steaming accessories, enabling grilling / steaming processing of food. In grilling mode, heating element assembly 31 and heating element assembly 32 work together to divide the inner cavity 2 into upper and lower chambers. The upper chamber forms a separately heated chamber, which helps to limit heat loss. At the same time, the chamber volume is small, resulting in higher heating efficiency.
