Description

Technical Field

[0001] The utility model belongs to the technical field of household cooking appliances, and particularly relates to an air fryer component and an air fryer with high-efficiency cold air exhaust. Background Art

[0002] An air fryer is a kitchen appliance that heats food using hot air. The air frying components in an air fryer mainly include a motor, a cold air hood, a hot air hood, a heating element, and a cold air fan. The typical structure is that the motor is mounted on the cold air hood, a cold air cavity is formed between the cold air hood and the hot air hood, the cold air fan is mounted in the cold air cavity, and the heating element is mounted in the hot air hood. The cold air hood is usually provided with an air inlet and an air outlet. When the cold air fan is in operation, it draws outside air from the air inlet into the cold air cavity, removes heat from the machine body that needs to be dissipated, and then discharges it to the outside through the air outlet. In the prior art, due to the unreasonable structural design of the cold air hood, when the cold air fan is in operation, the cold air easily forms turbulence in the cold air cavity, resulting in low exhaust pressure, insufficient exhaust flow, and unsatisfactory heat dissipation.

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figures 1 to 3 As shown, this embodiment provides an air frying assembly for efficiently exhausting cold air, comprising a motor 3, a cold air cover 1, a hot air cover 2, and a cold air fan 13; the cold air cover 1 and the hot air cover 2 form a cold air cavity 11, the cold air fan 13 is disposed in the cold air cavity 11, the motor 3 is disposed on the cold air cover 1, and the output shaft of the motor 3 is connected to the cold air fan 13;

[0033] The cold air hood 1 is provided with an air outlet 15, and the air inlet end of the cold air hood 1 is provided with a plurality of air inlet holes 14. In addition, an annular air guide portion 12 is provided in the middle of the air inlet end of the cold air hood 1, extending toward the middle of the cold air fan 13. The blades of the cold air fan 13 surround the outside of the annular air guide portion 12. Specifically, the annular air guide portion 12 is coaxially arranged with the output shaft of the motor 3, and the output shaft of the motor 3 passes through the annular air guide portion 12. The annular air guide portion 12 gradually extends toward the middle of the cold air fan 13 to the inside of the blades of the cold air fan 13.

[0034] Among them, such as Figures 1 to 3 As shown, an annular channel is formed between the outer wall of the annular air guide portion 12 and the inner wall of the cold air hood 1, and the exhaust port 15 is provided in the tangent direction of the annular channel. Specifically, a cold air exhaust channel 16 is provided near the side wall of the cold air hood 1 at a certain tangent point of the annular channel, and the exhaust port 15 is provided at the outlet end of the cold air exhaust channel 16. When the cold air fan 13 is in operation, it draws air from the air inlet 14. The drawn-in cold air is then discharged from the exhaust port 15 through the annular channel under the action of the cold air fan. The cold air flows along the annular channel, thereby avoiding turbulence in the cold air chamber 11, making the exhaust smoother and the cold air exhaust efficiency higher.

[0035] In this embodiment, as a specific implementation, the motor 3, cold air hood 1, cold air fan 13, and hot air hood 2 are arranged in order from back to front. The air inlet end of the cold air hood 1 is located on the rear wall of the cold air hood 1, and the air outlet 15 is located on the side wall of the cold air hood 1. The annular air guide 12 is arranged from back to front. This solution is suitable for air fryers with the air frying assembly located at the rear of the cooking chamber, such as double-layer air fryers, where each cooking chamber is independent and the air frying assembly is located at the rear.

The several air inlet holes 14 include at least two circles of air inlet holes 14, each circle of air inlet holes 14 being arranged around the middle of the rear wall.

[0037] The hot air hood 2 defines a hot air cavity 21, which communicates with the cooking cavity. A hot air fan 22 is disposed within the hot air cavity 21. The hot air hood 2 is provided with a through hole connecting the hot air cavity 21 and the cold air cavity 11. The output shaft of the motor 3 passes through the through hole and is connected to the hot air fan 22. In other words, the cold air fan 13 is coaxially disposed with the hot air fan 22. Specifically, when in operation, the hot air fan 22 draws air through the through hole into the hot air cavity 21, heats it into hot air, and then blows it into the cooking cavity.

[0038] In this embodiment, as another specific implementation, the motor 3, cold air hood 1, cold air fan 13, and hot air hood 2 are arranged sequentially from top to bottom. The air inlet end of the cold air hood 1 is located on the top wall of the cold air hood 1, and the air outlet 15 is located on the side wall of the cold air hood 1. The annular air guide 12 is arranged from top to bottom. This solution is suitable for air fryers in which the air frying component is located on the upper side of the cooking chamber.

The air discharged from the exhaust port 15 is discharged outward through the left or right wall of the air fryer body. The annular air guide 12 is arranged from back to front, and an air inlet connected to the air inlet hole 14 is provided on the rear wall of the body. An annular channel is formed between the outer wall of the annular air guide 12 and the inner wall of the cold air hood 1, and the exhaust port 15 is arranged tangentially to the annular channel. When in operation, the cold air fan 13 draws air from the air inlet hole 14. The cold air is then discharged from the exhaust port 15 through the annular channel under the action of the cold air fan.

[0042] As another specific embodiment, a cooking cavity is provided in the body, the air frying assembly is arranged on the upper side of the cooking cavity, the motor 3, cold air hood 1, cold air fan 13 and hot air hood 2 are arranged in sequence from top to bottom, the air inlet end of the cold air hood 1 is located on the top wall of the cold air hood 1, and the air outlet 15 is located on the side wall of the cold air hood 1; the annular air guide portion 12 is arranged from top to bottom, and an air inlet connected to the air inlet hole 14 is provided on the side wall of the body, and the air inlet can also be arranged on the bottom wall of the body.
