Description

Technical Field

[0001] The utility model relates to the field of kitchen appliances, in particular to a heating component for a compact microwave air frying oven. Background Art

[0002] A microwave air fryer oven is a kitchen appliance that combines microwave heating, air frying, and traditional baking functions, designed to provide versatile cooking methods to meet the needs of modern families. The heating elements used in compact microwave air fryer ovens typically have a compact design, making them suitable for small kitchens or limited spaces.

[0003] Microwave air fryers circulate high-temperature hot air to crisp the outside of food while keeping it tender inside, eliminating the need for large amounts of oil and fat, offering a healthier cooking option. However, due to the bulk of the microwave air fryer's heating element, the oven is also bulky, making it inconvenient to use and place. It is also difficult to fit into smaller areas and clean the interior, impacting the user experience. Therefore, a compact microwave air fryer heating element is proposed to address these issues. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a compact heating component for a microwave air fryer oven, aiming to improve the problem in the prior art that the heating component is too large, resulting in a large overall volume of the microwave air fryer oven.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A compact microwave air fryer heating assembly includes a hot air shaft, the exterior of the hot air shaft being fixedly connected to a drive assembly, the exterior of the hot air shaft being fixedly connected to heat dissipating blades, the bottom of the heat dissipating blades being fixedly connected to a limiting block, the lower end of the limiting block being fixedly connected to the hot air blades, and the exterior of the drive assembly being sheathed with a winding. The hot air shaft can rotate to generate heat, and the heat dissipating blades diffuse the heat into the surrounding air, converting it into hot air. The hot air is circulated by a hot air fan, thereby heating the food. The limiting block can limit the position of the hot air shaft to prevent the shaft from tilting or shifting.

[0007] As a further description of the above technical solution:

[0008] The drive assembly includes a coil, the inner side of which is fixedly connected to the outer side of the hot air shaft, and the bottom of the coil is slidably connected to a positioning member. The hot air shaft is the main rotating part, generating and transmitting force. The coil cuts the magnetic flux lines in the magnetic field, generating force and heat, which in turn drives the shaft to rotate on the positioning member.

[0009] As a further description of the above technical solution:

[0010] The outer side of the winding is fixedly connected with a clip, the top of the winding is fixedly connected with a fixing piece, and the two ends of the fixing piece are fixedly connected with small screws, and the small screws are threaded into the two sides of the winding. This increases the stability of the winding as a whole and prevents loosening and damage during operation.

[0011] As a further description of the above technical solution:

[0012] The outside of the small screw is fixedly connected to an electrode, the outside of the hot air shaft is covered with a hot air cover, and the outside of the hot air shaft is covered with an air guide cover. The top of the drive assembly is threadedly connected to a large screw, and the bottom of the drive assembly is fixedly connected to a locking block. This allows the hot air to circulate in the gap and makes the whole connection more stable, preventing damage to the equipment during rotation and enhancing overall stability.

[0013] As a further description of the above technical solution:

[0014] The top of the hot air hood is fixedly connected to the bottom of the anti-loosening block, and the outer side of the hot air hood is fixedly connected to an air inlet, and the outer side of the air inlet is fixedly connected to the outer shell. The air duct formed by the shell and the air inlet can inhale and exhaust air, so that the device can effectively dissipate heat after use and will not be damaged by high temperature.

[0015] The utility model has the following beneficial effects:

[0016] In this utility model, energizing the electrodes generates a magnetic field in the windings, driving the coils to rotate. This also causes the shaft fixed to the coils to rotate, driving the heat dissipation blades. Because the hot air blades are also fixed to the shaft, they also rotate together. The combined rotation of the hot air blades and the heat dissipation blades achieves efficient circulation and heating of the hot air within the microwave oven. Furthermore, because the hot air assembly is concave, the heat dissipation blades are lowered, reducing the overall height and making the microwave oven more compact.

The inner side of the coil 2 is fixedly connected to the outer side of the hot air shaft 1, and the bottom of the coil 2 is slidably connected to a positioning member 3. This component is used to fix and stabilize the position of the coil 2 on the hot air shaft 1 to ensure that the coil 2 will not shift due to vibration during operation.

[0027] The outside of the winding 7 is fixedly connected with a clip 8, which is used to fix the winding 7 and connect other components to ensure the stability and reliability of the device. The top of the winding 7 is fixedly connected with a fixing part 9, which is used to fix the clip 8 and other components to ensure the fastening of the entire structure. Both ends of the fixing part 9 are fixedly connected with small screws 10, which are used to connect various components to ensure the overall stability of the assembly. The small screws 10 are threadedly connected to both sides of the winding 7.

[0028] An electrode 11 is fixedly connected to the outside of the small screw 10, and the electrode 11 is used to connect to an external power supply to provide current to drive the operation of the equipment. A hot air hood 12 is provided on the outside of the hot air shaft 1, and the hot air hood 12 is used to wrap the hot air shaft 1 to concentrate heat and reduce heat loss.
