Technical Field

[0001] This utility model relates to an air fryer, which is a multifunctional 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 existing air fryers have a grilling plate and heating structure on the top of the body, such as Chinese patent application number 202321640803.4, authorized announcement date 2023.12.15, utility model title "An air fryer with grilling function on the top"; another example is Chinese patent application number 202411703837.2, published on application date 2025.02.25, invention title "A multifunctional cooking vessel"; however, the top of the above products and similar products only uses a grilling plate or a single pot body, and rarely adopts a steaming, frying and boiling integrated pot body, and the design of the heating structure and corresponding components at the bottom of the pot body is not good. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a multifunctional cooking appliance that addresses the technical problems of existing similar products rarely using a steaming, frying, and boiling integrated pot body, having inadequate design of the bottom heating structure and corresponding components, resulting in inconvenience in assembling and cleaning the top pot body, and having a relatively limited cooking method. This objective is achieved through the following technical solution.

[0004] A multifunctional cooking appliance has a steaming / frying / cooking pot on the top of its 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 body. A pot assembly is located in the metal partition at the front opening of the lower body. The upper through hole on one side of the metal partition above the lower pot body of the pot 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 a riveted steaming / frying pot body. The bottom of the pot body is placed within the heat insulation layer of the pot body in the groove at the top of the machine body. The heat insulation layer is fixedly installed on the machine body and integrated as a single unit. The top opening of the pot body is equipped with a steaming chamber featuring a steaming rack and a lid. The bottom opening of the steaming chamber and the inner diameter of the top opening of the pot body are fitted with steaming racks. The top opening of the steaming chamber is fitted with a lid. An upper heating element is riveted and fixed to the bottom of the pot body, and the bottom of the pot body is limited and partially extends out of the heat insulation layer. The bottom groove hole at the bottom of the heating layer is located on one side of the bottom of the steam rack, which abuts against the thermostat of the steaming / frying pot inside the machine. A fuse box is located in the middle of the bottom of the steam rack inside the machine. The upper fuse is fixed in the fuse box by a fuse clip. When the steaming / frying pot is placed on top of the machine, the upper fuse in the fuse box is connected to the upper heating element. The lower heating element, the shaded pole motor, the upper heating element, and the thermostat of the steaming / frying pot are connected to the power board assembly inside the machine and the PCB circuit board of the control panel assembly on one side of the machine through wiring. The steaming / frying pot and the steaming box are respectively equipped with lifting lugs.

[0005] The bottom of the steaming / frying pot body has a raised platform in the middle, and a positioning groove in the middle of the raised platform. An upper contact piece connected to the upper heating element is located within the positioning groove. When the steaming / frying pot body is placed on top of the main unit, two lower contact feet extending from the fuse box and connected to the upper fuse abut against the upper contact piece in the positioning groove at the bottom of the steaming / frying pot body. This facilitates the loading, unloading, and cleaning of the steaming / frying pot body without affecting the safety and stability of the upper fuse.

When the pot is placed on top of the main unit, the thermostat is inserted into the sleeve at the bottom. The upper heating element is positioned within the groove of the bottom groove and is horizontally fixed to the grooves and notches on both sides of the groove by four symmetrically arranged pipe clamps. The pipe clamps, grooves, and sleeves are flush, with the grooves and sleeves protruding above the protrusion at the positioning groove on the bottom of the pot. This ensures stable and stable placement of the pot and guarantees stable and safe heating operation.

[0007] The bottom of the steaming / frying pot body has a positioning plate on one side of the upper heating element wiring terminal, which protrudes above the bottom column sleeve, groove rib, and pipe clamp plate of the pot body. On the other side of the top of the metal partition inside the machine body, symmetrical to the positioning plate, there is a coupler and a top rod micro switch. The coupler and top rod micro switch are connected to the PCB circuit board via wiring. When the pot body assembly is placed into the opening on one side of the machine body, the top rod micro switch is triggered; when the steaming / frying pot body is placed on top of the machine body, the coupler is triggered. This further ensures the stability and safety of the steaming / frying pot body during heating.

[0008] 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 body 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 back-blowing air blasting mechanism and the water inlet partition.

[0009] The coupler and the push rod micro switch are located on the edge of the opening of the metal top cover. The front part of the groove of the lower heating tube inside the metal top cover is bent downward. A fuse fixing piece is provided on the outer diameter side of the metal top cover inside the machine body. The lower fuse at the fuse fixing piece is connected to the lower heating tube through a circuit.
