Description

Technical Field

[0001] This utility model relates to the field of air fryers, and more particularly to a volute structure for use in air fryers. Background Technology

[0002] In an air fryer, a motor drives a fan to blow heat from the heating coil to cook food. However, the motor itself also generates heat, which will accumulate if it is not dissipated efficiently in a timely manner. Utility Model Content

[0003] To address the aforementioned issues, this technical solution provides a volute structure for use in air fryers.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A volute structure for use in an air fryer includes a volute body, the volute body including a fan cavity for accommodating a fan, and a discharge cavity communicating with the fan cavity. The inner diameter of the discharge cavity gradually increases from the inside to the outside. The end face of the volute body is provided with multiple Archimedean spirals with a winding design.

[0006] In some embodiments, a cooling through hole is provided on the end face of the volute body opposite to the motor coil, and a sealing part is provided on the end face of the volute body opposite to the cooling through hole.

[0007] In some embodiments, the end face of the volute body is provided with a plurality of convection holes for docking with the circuit board box.

[0008] In some embodiments, the volute body is provided with a through hole through which the motor shaft passes, and fixing holes for fixing the motor are provided on both sides of the through hole.

[0009] In some embodiments, the inner wall of the discharge chamber is provided with a plurality of guide steps designed in an arc or slope shape.

[0010] In some embodiments, an extension is provided at the connection between the impeller chamber and the discharge chamber.

[0011] In some embodiments, the volute body is provided with a support frame for supporting the power supply box.

[0012] The beneficial effects of this application are:

[0013] This application concentrates the heat of the motor in the impeller cavity. As the impeller rotates, the heat is discharged through the exhaust cavity by utilizing the shape of the cavity. Since the exhaust cavity is funnel-shaped and uses an Archimedean spiral structure, the discharge efficiency is higher. Attached Figure Description

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please refer to Figure 1-4 As shown, the volute structure applied to an air fryer includes a volute body, the volute body including a fan cavity 100 for accommodating a fan, and a discharge cavity 101 communicating with the fan cavity 100. The inner diameter of the discharge cavity 101 gradually increases from the inside to the outside. The end face of the volute body is provided with a plurality of wound Archimedean spirals 102.

[0021] This application concentrates the heat of the motor in the impeller cavity. As the impeller rotates, the heat is discharged through the exhaust cavity by utilizing the shape of the cavity. Since the exhaust cavity is funnel-shaped and uses an Archimedean spiral structure, the discharge efficiency is higher.

[0022] In this embodiment, a cooling through hole 103 is provided on the end face of the volute body opposite to the motor coil. A sealing part 104 is provided on the end face of the volute body opposite to the cooling through hole 103. The sealing part closes two through holes at the front end of the volute surface near the exhaust port, and only the cooling through hole corresponding to the positive projection area of ​​the motor coil is opened. A rectangular hole is set for the coil. The air flows directly from the motor mounting area to the motor cooling channel. The ventilation channel only serves to cool the motor.

[0023] In this embodiment, the end face of the volute body is provided with a plurality of convection holes 105 for connecting to the circuit board box. These convection holes are connected to the air outlet of the circuit board box to form convection cooling.

[0024] In this embodiment, the volute body is provided with a through hole 106 through which the motor shaft passes, and fixing holes 107 for fixing the motor are provided on both sides of the through hole 106. The motor is mounted on the volute through the fixing holes, and the shaft passes through the through hole and is connected to the impeller. The impeller is located in the impeller cavity.

[0025] In this embodiment, the inner wall of the discharge chamber 101 is provided with a plurality of flow guide steps 108 with an arc or inclined surface design. The arc-shaped flow guide steps are conducive to guiding the air out during heat dissipation.

[0026] In this embodiment, an extension 109 is provided at the connection between the impeller cavity 100 and the discharge cavity 101 to prevent convection from forming at this location, so that the wind power is discharged in one direction.

[0027] In this embodiment, the volute body is provided with a support frame 110 for supporting the power supply box.

[0028] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
