Description

Technical Field

[0001] The utility model relates to an air fryer. Background Art

[0002] An air fryer is a modern kitchen appliance that cooks food through hot air circulation technology. Its basic structure includes the following main parts: a housing, an inner pot, a heating element, a fan, a control panel, and a hot air channel. The housing is usually made of plastic or metal, which plays a role in protecting the internal structure and being aesthetically pleasing; the inner pot is used to place the food to be cooked, generally made of stainless steel or aluminum with a non-stick coating, which is convenient for cleaning and preventing food adhesion; the heating element is mainly responsible for generating heat, which can be an electric heating tube or a quartz tube; the fan is used to push the hot air to circulate inside the pot; the control panel provides an operation interface, and the user can set the temperature and time; the hot air channel is the path for the hot air to circulate inside the pot. During the working process of the air fryer, the heating element generates high temperature, and the fan pushes the hot air to circulate through the hot air channel to heat the food. A hot air channel is formed between the housing of the air fryer and the hot air outlet. Through this channel, the hot air can be evenly distributed in every corner of the pot. However, the hot air outlet is usually designed to be square, and dead corners are easily formed at the junction of this design and the housing, thus hindering the air circulation in the hot air channel. Further, this design defect will also cause heat accumulation at the position where the hot air outlet is located downstream of the hot air channel. The occurrence of heat accumulation will bring several problems. First, the temperature at the hot air outlet part will increase significantly, which poses higher requirements on the materials of the air fryer. In particular, the hot air outlet needs to use materials with higher heat resistance. If the heat resistance of the material is not good enough, it may be damaged due to high temperature, affecting the service life of the air fryer. Second, due to the blocking effect of the hot air outlet, the poor air flow will cause a large wind noise when the fan operates, reducing the user experience. Summary of the Utility Model

[0022] The following further describes the present invention in conjunction with the drawings and specific embodiments.

[0023] Refer to Figures 1 - 5, an air fryer, which includes an air fryer body 1 and a ventilation system. The air fryer body 1 includes a housing 11, a heating component 12, and a cooking container 13. The housing 11 forms a ventilation space, which is divided into a first space 113 and a second space 112 by a heat insulation cover 14. The ventilation space further includes a heat dissipation space 114, which is arranged around the first space 113 and the heat dissipation space 114 communicates with the second space 112. The ventilation system includes a first fan blade 22, a second fan blade 21, and a driving mechanism 23. The driving mechanism 23 is arranged inside the housing 11. The first fan blade 22 is located in the first space 113, and the second fan blade 21 is located in the second space 112. The driving mechanism 23 is connected to both the second fan blade 21 and the first fan blade 22 through a driving shaft 24, and the driving shaft 24 passes through the heat insulation cover 14. The cooking container 13 is removably placed in the first space 112, and the heating component 12 is located below the first fan blade 22. When the first fan blade 22 rotates, air flow blows through the heating component 12 towards the cooking container 13 to heat and cook the food in the cooking container 13.

[0024] The first fan blade 22 is located in the first space 113 to drive the air circulation in the cooking container 13, and the second fan blade 21 is located in the second space 112 to drive the air circulation in the second space 112 and the heat dissipation space 114. The ventilation system further includes an air outlet component 25, which includes a first air outlet 252 and a second air outlet 251. The first air outlet 252 is connected to the first space 113, and the second air outlet 251 is connected to the second space 112. The convex peripheral wall 253 of the air outlet component 25 facing the second space 112 and the heat dissipation space 114 is elliptical.

[0025] During use, the driving mechanism 23 drives the first fan blade 22 and the second fan blade 21 to rotate through the driving shaft 24. The air flow first flows into the second space 112 from the air inlet of the housing 11, enters the first space 113 through the heat insulation cover 14, and the air flow passes through the heating component 12 and enters the cooking container 13. Since the second fan blade 21 will drive the air to flow around it, the air flow will flow along the peripheral walls of the second space 112 and the heat dissipation space 114. At this time, since the convex peripheral wall 253 of the air outlet component 25 is elliptical, the air flow can flow along the outside of the convex peripheral wall 253, so that heat will not accumulate around the air outlet component 25. The air flow in the first space 113 can flow out to the outside through the first air outlet, and the air flow in the second space 112 and the heat dissipation space 114 can flow out to the outside through the second air outlet 251.

[0026] In this embodiment, the second space 112 is located above the first space 113, and the air outlet component 25 is horizontally placed at the connection of the first space 113 and the second space 112. Therefore, when the air flow passes through the convex peripheral wall 253, it flows along the long side of the ellipse. The first air outlet 252 and the second air outlet 251 extend horizontally. Specifically, the upper half of the convex peripheral wall 253 is located in the second space 112, and the lower half of the convex peripheral wall 253 is located in the heat dissipation space 114; the second fan blade 21 drives the air flow to flow along the outer side of the lower half of the convex peripheral wall 253 and along the outer side of the upper half of the convex peripheral wall 253.

[0027] The air inlet of the first space 113 is located at the heat insulation cover 14. The heat dissipation space 114 further includes a bottom air outlet 26 at its bottom. Therefore, the air flow can also flow out through the bottom air outlet 26.

[0028] In this embodiment, the air fryer body 1 further includes an upper housing 15. A second space 112 is formed between the upper housing 15 and the heat insulation cover 14. The convex peripheral wall 253 of the air outlet component 25 facing the second space 112 and the heat dissipation space 114 is elliptical. When the air flow passes through the convex peripheral wall 253, the wind resistance and wind noise of the air flow can be reduced. And due to the streamline structure of the ellipse, heat accumulation will not occur in a certain part, so that the temperature of the second space 112 and the heat dissipation space 114 can be better reduced. Furthermore, the temperature of the upper housing 15 will not be too high, and the temperature of the upper housing 15 will be lower than the temperature of the air outlet component 25.

[0029] And since the upper housing 15 and the air outlet component 25 are not of an integral structure, for example, bolts and other fixing parts can be used to fixedly assemble the air outlet assembly to the upper housing, but not limited thereto. Therefore, the upper housing 15 can be made of a low-temperature resistant material with a lower heat resistance strength than that of the air outlet component 25 and a lower cost.

[0030] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, making non-substantive modifications to the present invention using this concept, shall fall within the scope of infringement of the protection of the present invention.
