Description

Technical Field

[0001] This utility model relates to the frying basket of an air fryer, which is an air fryer with an electromagnetic lock structure. 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 electric fryers, it reduces the amount of oil in the food by 80%, is easy to clean in daily use, and is both safe and economical, making it very popular. Some air fryer basket components require electromagnetic locks to ensure safe operation, such as Chinese patent application number 202010462212.7, published on December 3, 2021, entitled "A Microswitch and an Air Fryer with the Microswitch." This air fryer's triggering mechanism includes a transmission rod and a pivot fixed perpendicularly to the transmission rod. The transmission rod has a front end, a body, and a rear end. The pivot is pivotally mounted on a pivot support. A junction box is also included, mounted on a base and comprising a housing, a normally open switch circuit, and external terminals. The rear end of the rod and the normally open switch circuit can cooperate to form a closed loop in the main control circuit. However, the electromagnetic locks in the aforementioned air fryers and similar products occupy a large space, have high production costs, complex structural designs, and are inconvenient to use and assemble. Summary of the Invention

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide an air fryer with an electromagnetic lock structure, thereby solving the technical problems of complex electromagnetic lock structure design, high production cost, and inconvenient assembly in existing similar products. This objective is achieved through the following technical solution.

[0004] An air fryer with an electromagnetic lock structure is disclosed. The air fryer basket assembly includes a handle, a basket liner, and a basket shell. The basket assembly is inserted into the machine body through an opening on one side of the machine body. The key structural design feature is that the top edge of the basket liner has a through hole in the middle. One end of the moving iron core of the electromagnetic lock is inserted into the through hole of the basket liner. The electromagnetic lock is fixedly installed in the air guide shroud above the top edge of the basket assembly in the machine body. The basket shell is fixed to the shroud opening on the outside of the basket liner by screws on the inside of the basket liner. The electromagnetic lock is connected to a circuit board via wiring.

[0005] The electromagnetic lock has an L-shaped groove on one side of the housing of the moving iron core, and a rectangular hollow cavity on the other side of the housing. A spring and a retaining ring are located at the other end of the moving iron core extending from the housing. An electromagnetic coil is located on the inner wall of the outer housing of the moving iron core inside the electromagnetic lock. The hollow cavity of the electromagnetic lock facilitates the installation of the electromagnetic lock through the rear or top and bottom parts of the cavity as needed.

[0006] The diameter of one end of the moving iron core spring is larger than the diameter of the other symmetrical end. This improves the stability of the moving iron core and the service life of the spring.

[0007] The lining of the frying basket has a limiting rib at the reinforcing rib below the through hole. This controls the stroke of the moving iron core and extends the service life of the through hole.

[0008] This utility model has a reasonable structural design, low production cost, wide applicability, convenient assembly and production, and small space occupation; it is suitable for use as an air fryer with an electromagnetic lock structure, as well as for structural improvements of similar products.

[0014] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figures 1-4As shown, the air fryer takes a large double-cavity frying basket assembly with two handles as an example; the frying basket assembly 1 of the air fryer includes a handle 101, a frying basket liner 102 and a frying basket shell 103. The frying basket assembly is inserted into the machine body through an opening on one side of the machine body; a through hole is provided at the top edge of the middle of the frying basket liner of the frying basket assembly. One end of the moving iron core 201 of the electromagnetic lock 2 is inserted into the through hole of the frying basket liner. The electromagnetic lock is fixedly installed on the air guide cover 3 above the top edge of the frying basket assembly in the machine body. The frying basket shell is fixed to the cover opening on the outside of the frying basket liner by screws on the inside of the frying basket liner. The electromagnetic lock is connected to the circuit board through a circuit. Heating elements 4 and metal centrifugal fan blades are respectively installed in the recessed areas of the air guide hoods on both sides. A light bulb 5 is installed on one side of the recessed area of ​​the air guide hood. A plastic centrifugal fan blade 6 and a motor 7 are respectively installed on the top of the air guide hood. The motor shaft of one side of the motor is connected to the corresponding plastic centrifugal fan blade and metal centrifugal fan blade. The motor, heating elements, and light bulbs are connected to the circuit board through wiring. The box between the motors is the circuit board box. The exhaust hood on one side of the air guide hood is connected to the channel inside the air guide hood. A heat dissipation hood can also be further installed on the top of the air guide hood. The plastic centrifugal fan blade is installed inside the heat dissipation hood. One side of the heat dissipation hood is connected to the exhaust hood.

[0015] The specific structure of the electromagnetic lock is as follows: The housing on one side of the moving iron core of the electromagnetic lock is provided with an L-shaped side groove, and the housing on the other side is provided with a rectangular hollow cavity. The other end of the moving iron core extends out of the housing and is provided with a spring 202 and a retaining ring 203. An electromagnetic coil is provided on the inner wall of the outer housing of the moving iron core inside the electromagnetic lock. The diameter of one end of the spring of the moving iron core is larger than the diameter of the other end. A limiting rib 1021 is provided at the reinforcing rib below the through hole of the blast basket lining.

[0016] The working principle of this air fryer is as follows: When in operation, the electromagnetic lock is energized, and the moving iron core of the electromagnetic lock moves downward and inserts into the through hole of the inner lining of the frying basket, which is in a locked state. The frying basket assembly cannot be pulled out at will. It can only be unlocked when the operation is paused, manually canceled, or after the operation is completed. Only then can the frying basket assembly be pulled out.

[0017] In summary, this air fryer has the following features: 1. Ensuring safety: When the air fryer is working, the electromagnetic lock locks the basket assembly to prevent accidental opening, ensuring that the user will not open the basket assembly while the device is running, thus avoiding burns or other safety accidents. 2. Preventing accidental operation: The electromagnetic lock ensures that the basket assembly cannot be opened while the air fryer is running. The electromagnetic lock can only be unlocked and the basket assembly can be opened after the operation is paused, manually canceled, or completed; this also prevents problems caused by accidental operation while the air fryer is running. 3. Enhancing the user experience: The electromagnetic lock design makes the air fryer safer and more reliable during operation, allowing users to use the device for cooking with greater peace of mind.
