Description

Technical Field

[0001] This utility model relates to the field of microwave oven technology, and specifically to a microwave oven with an air frying function. Background Technology

[0002] With the rapid development of modern kitchen appliances, microwave ovens and air fryers have become indispensable cooking tools for many families. Microwave ovens have a microwave cooking function, which mainly heats food from the inside out; while air fryers use high-speed hot air circulation technology to cook food. In order to combine the advantages of microwave ovens and air fryers, microwave ovens with air frying functions, namely air fryer microwave ovens, have appeared on the market.

[0003] For example, utility model patent CN216431825U discloses a microwave oven with an air frying function, including a shell assembly, an air frying assembly, and a microwave generating assembly. The shell assembly has a cavity for containing food. The air frying assembly is fixedly installed on the upper part of the shell assembly and generates hot air to blow into the cavity to achieve air frying cooking. The microwave generating assembly is located on the left or right side of the cavity and includes a magnetron and a working circuit for generating microwaves to heat the food. However, during use, the motor of the air frying assembly in this prior art generates significant vibration and noise, resulting in unsatisfactory user experience.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problem that existing air fryer components generate significant vibration and noise during operation, resulting in unsatisfactory user experience, this invention provides a microwave oven with an air fryer function.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A microwave oven with an air frying function includes an oven body with a cooking cavity inside. A microwave assembly and an air frying assembly are mounted on the oven body. Microwaves generated by the microwave assembly and hot air generated by the air frying assembly can enter the cooking cavity to cook food. The air frying assembly includes a frying cavity assembly, a heating element assembly, and a turbine head assembly. The frying cavity assembly is detachably installed in the cooking cavity. The turbine head assembly and the heating element assembly are correspondingly arranged. The turbine head assembly includes a motor base, a brushless DC motor, motor fan blades, a heat insulation plate, and turbine fan blades. The brushless DC motor is mounted on the motor base, and shock-absorbing silicone rubber is provided between the brushless DC motor and the motor base. The motor fan blades and the turbine fan blades are connected vertically to the drive shaft of the brushless DC motor, and the heat insulation plate is located between the motor fan blades and the turbine fan blades. This configuration uses a brushless DC motor, motor fan blades, and turbine fan blades as the power drive for the air blasting function. Furthermore, the presence of shock-absorbing silicone rubber between the brushless DC motor and the motor mount ensures that the brushless DC motor does not generate significant vibration or noise during operation, resulting in a more ideal user experience.

[0008] According to the above scheme, the heat insulation plate has a heat insulation plate recess, the first end of the brushless DC motor is mounted on the motor base, and the heat insulation plate recess is correspondingly set with the second end of the brushless DC motor to form a first safety gap. This setting makes assembly more convenient and the overall size can be made smaller; moreover, when the brushless DC motor is working, the motor fan blades and the heat insulation plate will not interfere with each other.

[0009] According to the above scheme, the turbine blade has a turbine blade recess, which corresponds to the heat insulation plate recess and forms a second safety gap. This design makes assembly easier and allows for a smaller overall size; moreover, the turbine blade and the heat insulation plate will not interfere with each other when the DC brushless motor is working.

[0010] According to the above scheme, the heat insulation plate divides the motor base into an upper cavity and a lower cavity. The motor fan blades are located in the upper cavity, and the turbine fan blades are located in the lower cavity. The motor base is provided with a heat dissipation and dehumidification port that communicates with the upper cavity. The turbine fan blades are correspondingly arranged with the heating element assembly, which includes an annular heating element. This arrangement results in higher efficiency in generating hot air and allows the heat from the DC brushless motor and the moisture in the cooking cavity to be discharged through the heat dissipation and dehumidification port.

[0011] According to the above scheme, the oven body includes a top plate, a left side plate, a rear plate, a right side plate, a front panel, and a bottom plate that are fixedly connected. The front panel has a cooking cavity opening, and the bottom plate is covered with microcrystalline glass. The turbine head assembly is mounted on the top plate, and the microwave assembly is mounted on the bottom plate. This arrangement, with the turbine head assembly mounted on the top plate and the microwave assembly mounted on the bottom plate, makes reasonable use of the installation space.

[0012] According to the above scheme, the top plate is provided with a circular sealing platform, which corresponds to the opening of the heat insulation plate of the turbine head assembly to form a seal; the circular sealing platform is provided with multiple reinforcing ribs, multiple air outlets, and multiple air return holes, with the multiple air outlets arranged in a ring around the outer periphery of the multiple air return holes. With this configuration, when the air fryer is working, the hot air forms a vortex, heating and circulating the food in the frying chamber assembly for better heating effect.

[0013] According to the above scheme, the microwave assembly includes a magnetron, a waveguide, and a microwave dispersion disk. The magnetron is mounted on the base plate via a support, and the magnetron and waveguide are correspondingly arranged. The waveguide and microwave dispersion disk are correspondingly arranged, and the microwave dispersion disk is located below the microcrystalline glass. This arrangement allows for better heating and cyclic cooking of the food on the microcrystalline glass through the microwave dispersion disk during operation.

[0014] According to the above scheme, the frying cavity assembly includes a frying cavity plate, a wire mesh frame, and an insulating and heat-insulating silicone rubber ring. The wire mesh frame is detachably installed inside the frying cavity plate, and the insulating and heat-insulating silicone rubber ring is fixed to the opening of the frying cavity plate. The frying cavity plate is a square stamped part, a square die-cast part, a round stamped part, a round die-cast part, or a glass or ceramic part. This design allows oil stains generated during food heating to fall into the frying cavity plate and separate from the food on the wire mesh frame, thanks to the wire mesh frame. The insulating and heat-insulating silicone rubber ring on the opening of the frying cavity plate provides better heat insulation, preventing burns during removal and making it safer to use.

[0015] According to the above scheme, the frying chamber plate opening is provided with a fixing hole, and the insulating and heat-insulating silicone rubber ring is provided with a fixing nail. The insulating and heat-insulating silicone rubber ring is clamped onto the frying chamber plate opening and is locked in place by the fixing nail and the fixing hole. This design facilitates assembly.

[0016] According to the above scheme, the insulating and heat-insulating silicone rubber ring is a matte frosted molded part, and the outer edge of the insulating and heat-insulating silicone rubber ring is provided with multiple protrusions. This design reduces damping friction when the frying tray is assembled into the cooking cavity, resulting in smoother assembly.

[0017] The beneficial effects of this utility model are:

[0018] This utility model is designed to use a DC brushless motor, motor fan blades, and turbine fan blades as the power drive for the air blasting function. It also incorporates shock-absorbing silicone rubber between the DC brushless motor and the motor base, which prevents the DC brushless motor from generating significant vibration and noise during operation, thus providing consumers with a more ideal user experience.
