Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] like Figure 1 As shown, this utility model discloses a multifunctional cooking device, including a shell, an inner liner inside the shell, a cooking cavity formed inside the inner liner, and a removable food utensil inside the cooking cavity. In this embodiment, the food utensil is a baking pan with an oil drain hole. A loading / unloading opening is provided on one side of the shell and the inner liner, and a flip-up door is provided at the loading / unloading opening for easy access to the food utensil.

[0033] The housing also houses a hot air assembly located above the cooking cavity and a burner assembly located below the cooking cavity. A mounting cavity is formed between the top of the inner liner and the housing, within which the hot air assembly is housed. An air guide plate is fixed to the outer side of the top surface of the inner liner, and a motor bracket is fixed above the air guide plate. The hot air assembly includes a motor, hot air blades, and a heating element. The motor is fixed to the motor bracket, and the hot air blades and heating element are located between the reflector and the inner liner. The motor output shaft passes through the reflector and connects to the hot air blades, driving the blades to rotate. Hot air holes are provided in the inner liner corresponding to the area where the reflector is located, delivering hot air into the cooking cavity.

[0034] The burner assembly is detachably connected to the bottom of the inner liner. The burner assembly includes a combustion tube and a flame distributor. A perforation is provided on the inner liner. The combustion tube includes a first end passing through the perforation and a second end detachably connected to the inner liner. The first end extends between the inner liner and the outer shell to receive fuel gas. Specifically, the combustion tube extends horizontally perpendicular to the access port, and the second end is located on the access port side. When cleaning the inner liner or flame distributor, or repairing the burner, since the first end passes through the perforation and the second end is detachably connected to the inner liner, simply detach the second end from the inner liner to remove the combustion tube and flame distributor. This facilitates cleaning the inner wall of the inner liner and removing the flame distributor, or inspecting and repairing the burner. After cleaning or repair, align the first end with the perforation, insert the combustion tube and flame distributor into the inner liner, and finally reattach the second end to the inner liner to complete the installation. Installation is convenient and maintenance and cleaning are easy. The second end is located on the pick-up / drop-off side, making it easier for users to operate the second end of the combustion tube for installation and removal.

[0035] A support strip is installed on the bottom surface of the inner liner. Both ends of the support strip are fixed to two opposite vertical inner walls of the inner liner. The second end of the burner tube abuts against the upper surface of the support strip, and a pin is inserted through the second end of the burner tube and the support strip for detachable installation. During use, food utensils will leak grease and moisture onto the bottom surface of the inner liner. The support strip creates a gap between the burner and the bottom surface of the inner liner, maintaining distance and reducing the possibility of contact with grease and moisture, thus improving safety. Furthermore, it raises the operating surface, making it easier for the user to operate the second end of the burner tube.

[0036] The burner includes a covering area directly above the combustion tube and the remaining ventilation area, with multiple evenly spaced ventilation holes. The burner's coverage area ensures proper combustion of the combustion tube, specifically by: 1. reducing the potential impact of grease and moisture leaking from food containers on the combustion tube; 2. minimizing the impact of hot air on the flame when the hot air assembly and burner assembly are used simultaneously. The burner extends perpendicular to the length of the burner and is the same width as the food container, ensuring it covers the entire width of the container, guaranteeing heating efficiency, and improving the uniformity of food cooking.

[0037] In this embodiment, the top surface of the combustion tube and the bottom surface of the area covered by the igniter are fixed together by spot welding.

[0038] See Figure 2 The burner assembly also includes an igniter, which is located below the coverage area of ​​the flame spreader to ensure its operation; a thermocouple is also installed below the coverage area to detect the temperature of the burner assembly.

[0039] See Figure 1The back of the housing is equipped with a first interface, one end of which is located outside the housing and connected to the gas source; the first end of the combustion tube is aligned with the second interface. A gas valve and an air-blast control panel are provided on the same side of the housing as the loading and unloading port. One end of the gas valve extends into the mounting cavity and is connected to the first and second interfaces (not shown in the figure), thereby adjusting the amount of gas.

[0040] The inner pot has an oil outlet on its bottom surface, which is sloped, with the oil outlet being the lowest point. An oil collection box is located directly below the oil outlet on the outer shell, and is detachably connected to the bottom of the shell. Oil and moisture leaking from the food containers reach the bottom of the inner pot through the ventilation holes on the burner; then, they are collected in the oil collection box through the oil outlet on the bottom of the inner pot. Specifically, the bottom of the shell protrudes downwards to form a space for the oil collection box, which is open on one side for easy access. Users do not need to remove the oil collection box from inside the cooking appliance; it can be removed directly from the outside of the appliance, making assembly and disassembly convenient.

[0041] The bottom of the shell has a hole for supplying air to the burner. The air enters the bottom of the cooking cavity from the oil outlet of the inner liner.

[0042] The working principle of the above-described implementation is as follows: The cooking equipment can achieve three cooking modes: ① both the hot air assembly and the burner assembly are activated; ② only the hot air assembly is activated, achieving air frying; ③ only the burner assembly is activated, achieving grilling. During the cooking process, oil and moisture enter the bottom of the inner pot through the oil drain hole of the food container, and are collected in the oil collection tray through the oil outlet hole on the bottom of the inner pot. After cooking, the oil collection tray can be removed from the outside of the shell for cleaning. If it is necessary to clean the inner pot or the burner assembly, the pin can be removed to remove the burner tube and the flame distributor from the cooking chamber; during installation, simply align the first end of the burner tube with the perforation, insert the burner tube and the flame distributor into the inner pot, and then install the pin onto the second end of the burner tube and the support bar.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
