Description

Technical Field

[0001] This utility model relates to an air fryer with a steaming / frying / cooking pot on the top, which is a new type of cooking appliance. Background Technology

[0002] An air fryer is a new type of household appliance that uses high-speed air circulation technology to fry food. Compared to traditional fryers, it reduces oil content by up to 80%, is easy to clean, and is both safe and economical, making it very popular. Currently, air fryers on the market mainly consist of two parts: a heating element and a frying pan. The heating element is generally located at the top of the main unit, while the frying pan is at the bottom, containing a grill rack. Some air fryers currently have a steaming / frying / cooking pot on top of the main body, such as Chinese patent application number 202510799857.2, published on August 19, 2025, entitled "A Cooking Appliance". This cooking appliance has a steaming / frying / cooking pot on top and a back-blowing air frying mechanism in the lower rear part of the main body. The key feature is that the steaming / frying / cooking pot is a riveted type, with its bottom inserted into the heat insulation layer of the pot body in a recessed area on the top of the main body. The heat insulation layer is fixedly installed on the main body and integrated with it. The top opening of the steaming / frying / cooking pot has a steaming box with a steaming rack and a lid. An upper heating element is riveted and fixed to the bottom of the steaming / frying / cooking pot. One side of the bottom of the steaming rack abuts against the thermostat of the steaming / frying / cooking pot inside the main body. A fuse box is located in the middle of the bottom of the steaming rack inside the main body. When the steaming / frying / cooking pot is placed on top of the main body, the upper fuse in the fuse box connects to the upper heating element. However, the complex design of the pot body and corresponding safety structure of the above products makes production and assembly inconvenient and production costs high. The heat dissipation effect of the top of the machine body is also required to be high, making it difficult to meet the requirements of steaming, boiling and grilling. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a novel cooking appliance that addresses the technical problems of existing similar products rarely adopting a structural design that integrates steaming, boiling, frying, and air-frying functions, particularly the inadequate design of the top pot bottom heating structure and corresponding components, making it difficult to meet the technical requirements of heat dissipation from the top of the appliance and steaming, boiling, and frying. This objective is achieved through the following technical solution.

[0004] A novel cooking appliance has an upper pot body on the top of its main body and a back-blowing air frying mechanism consisting of a shaded-pole motor, a plastic centrifugal fan, and a metal centrifugal fan in the lower rear part of the main body. A pot body assembly is located in the metal partition at the front opening of the lower main body. The pot body assembly includes a lower handle, a lower pot body, and a lower grill rack. An upper through hole on one side of the metal partition above the lower pot body of the pot body assembly communicates with the rear chamber of the metal partition, and is aligned with the pot body through hole equidistantly located on one side of the lower pot body through the lower through hole in the metal partition of the rear chamber. A lower heating element is located in the groove of the metal partition above the lower pot body. The key structural design features an upper metal heat-insulating liner inside the opening of the metal partition above the lower heating element. This liner is fixedly installed in the body and integrated with it. A heating plate is located at the bottom of the upper metal heat-insulating liner inside the body, with a temperature sensor in the center. When the bottom of the upper pot is placed into the upper metal heat-insulating liner in the groove at the top of the body, the bottom of the upper pot simultaneously contacts the heating plate and the temperature sensor. The shaded-pole motor, lower heating element, heating plate, and temperature sensor are connected via wiring to the power board assembly inside the body and the PCB circuit board at the control panel assembly on one side of the body. The top opening of the upper pot is equipped with a steaming rack with a lid, or the bottom of the steaming box has a steaming mesh, and the top of the steaming box has a lid. The outer diameter of the steaming box or steaming rack is symmetrically equipped with lifting lugs. The aforementioned temperature sensor is not limited to a spring-loaded anti-dry-burning temperature sensor. Thus, this appliance combines three functions: steaming, frying, and air frying. The lower part of the appliance uses the back-blowing principle to achieve the air frying function; the upper pot body is attached to the heating plate to achieve the steaming and frying functions.

[0005] A protective component is provided between the bottom of the upper metal heat insulation liner and the top of the metal partition. The protective component is a protective plate or protective cover that isolates the temperature between the lower heating tube and the heating plate. The protective cover is connected to the exhaust hole on one side of the lower body.

[0006] The heating plate is circular, and the bottom of the upper metal heat-insulating liner has a corresponding circular protrusion. The bottom of the upper pot body has a corresponding pot protrusion. The above is a specific structural embodiment of the heating plate, but it is not limited to the above structure.

[0007] The metal partition includes a metal top cover, a metal inner liner, and a metal bottom liner. The metal partition, consisting of the metal top cover, metal inner liner, and metal bottom liner, has an upper through-hole at the rear of the metal top cover. The lower heating element is located inside the metal top cover above the pot opening of the lower pot assembly. The upper through-hole at the rear of the metal top cover communicates with the metal heat insulation cover at the rear of the metal inner liner. The metal centrifugal fan blades inside the metal heat insulation cover are aligned with the pot body through-holes in the lower pot body, which are equidistantly arranged through the lower through-holes in the metal inner liner. The plastic air guide at the rear of the metal heat insulation cover is connected to the exhaust hood on one side of the machine body through an exhaust hole on one side. The motor shaft of the shaded-pole motor is connected to the plastic centrifugal fan blades inside the plastic air guide through the plastic air guide, and the metal heat insulation cover is connected to the metal centrifugal fan blades inside the metal heat insulation cover. The above is a specific structural embodiment of the metal partition, but it is not limited to the above structure.

[0008] The metal top cover has equally spaced, waist-shaped upper cooling channel holes at its brim, and the corresponding metal bottom liner has equally spaced, waist-shaped lower cooling channel holes. The upper and lower edges of the cover of the pot body assembly corresponding to the upper and lower cooling channel holes have corresponding cover channel holes.

[0009] An NTC temperature sensor is provided on one side of the metal top cover, extending into and located on the side of the lower heating element. The NTC temperature sensor is connected to the PCB circuit board via a circuit.

[0010] The control screen assembly of the power board assembly is obliquely protruding on one side of the machine body above the pot body assembly, and the control screen assembly is rectangular.

[0011] This utility model has a reasonable structural design, good heat dissipation and ventilation, good safety and stability, and multiple functions. In particular, in addition to the air fryer function, it also has steaming and grilling functions. It is mainly used as an air fryer that integrates steaming, grilling, and air frying functions, as well as structural improvements to similar products. Attached Figure Description
