Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooking equipment, in particular to an easy-to-clean air fryer. BACKGROUND

[0002] When the air fryer is used to cook food, the processed food is first placed in the basket, then the basket is pushed into the cooking cavity of the main body and is ensured to be in place. By controlling the assembly to start the machine, the heating pipe and the motor start to work, and the motor drives the centrifugal fan blade to rotate at high speed to form a high-speed airflow in the basket cavity, and the heat generated by the heating pipe is brought into the basket, so that the food in the basket is fully contacted with the high-temperature airflow and heated to be cooked.

[0003] However, the heating pipe of the existing air fryer is directly designed on the upper part of the cooking cavity of the main body, and the basket is arranged below the heating pipe. When the air fryer works, the centrifugal fan blade rotates at high speed under the drive of the motor to drive the air in the cooking cavity to circulate at high speed. The air flows through the heating pipe to the basket under the action of the centrifugal fan blade, and then flows from the bottom of the basket to the centrifugal fan blade through the heating pipe, and so on.

[0004] However, during the roasting process of the food, a large amount of water vapor and oil will be generated and discharged as the temperature rises. The water vapor and oil will also circulate repeatedly under the action of the high-speed airflow. The oil carried by the high-speed airflow will adhere to the heating pipe and the fan blade during the flow process. As the use time of the product increases, the adhered oil will also increase. In addition, the heating pipe is mostly designed in a mosquito coil shape, which is very difficult to clean. Especially the centrifugal fan blade is located above the heating pipe and is completely blocked by the heating pipe, so it cannot be cleaned. Over time, the oil will become oil stains, which will produce an odor during operation. More seriously, the oil may undergo various chemical reactions under high temperature and become toxic substances, which seriously threaten the health and safety of consumers.

Optionally, the heating component 3 can be disposed in the air outlet 53. In this way, the cold airflow output by the fan component 2 flows into the air guide 54, and then the air guide 54 evenly diffuses the cold airflow into the air outlet 53. Then, the heating component 3 in the air outlet 53 heats the cold airflow into hot airflow, and then evenly diffuses the hot airflow. The air is injected into the cooking cavity 11 to uniformly heat the cooking cavity 11. Optionally, the heating component 3 can be disposed between the air outlet section 51 and the cooking cavity 11. In this way, the cold airflow output by the fan component 2 flows into the air guide channel 54, and then the air guide channel 54 evenly diffuses the cold airflow to the air outlet channel 53. Then, the cold airflow output by the air outlet channel 53 is heated into hot airflow by the heating component 3 and then evenly injected into the cooking cavity 11 to uniformly heat the cooking cavity 11.

Optionally, the flow distribution portion 55 and the air outlet section 51 are independent of each other, combined by several components, and form the air outlet channel 53; optionally, the flow distribution portion 55 and the air outlet section 51 are integrally formed; optionally, the air guide assembly 5 includes an outer shell, which is divided into the air guide section 52 and the air outlet section 51 from top to bottom, and the flow distribution portion 55 is a separate component arranged at the middle of the air outlet section 51; optionally, the air guide assembly 5 includes an air guide outer shell and an air guide bottom shell, the air guide outer shell is divided into the air guide section 52 and the air outlet section 51 from top to bottom, and the air guide bottom shell is arranged at the lower end of the air guide outer shell (i.e. the lower end of the air outlet section 51), and the middle of the air guide bottom shell is concave upward to form the flow distribution portion 55, and the outer periphery of the flow distribution portion 55 and the inner wall of the air guide outer shell form the air outlet channel 53. Preferably, the air outlet channel 53 formed by the flow distribution portion 55 and the air outlet section 51 is annularly arranged, so that the air outlet channel 53 can uniformly inject air flow into the cooking cavity 11, avoiding the phenomenon of uneven heating of food in the cooking cavity 11.

[0032] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the heating assembly 3 is arranged in the air outlet channel 53, so that after the air guide channel 54 uniformly diffuses cold air flow into the air outlet channel 53, the heating assembly 3 heats the cold air flow into hot air flow, and then the air outlet channel 53 uniformly injects the hot air flow into the cooking cavity 11 to uniformly heat the cooking cavity 11; optionally, the heating assembly 3 includes an electric heating sheet, an electric heating rod, an electric heating wire, etc.; preferably, the heating assembly 3 includes a heating pipe 31, which is accommodated in the air outlet channel 53 and wound on the flow distribution portion 55. In this embodiment, the heating pipe 31 is wound on the flow distribution portion 55 to increase the contact area and the number of contacts between the heating pipe 31 and the cold air flow flowing through the air outlet channel 53, effectively improving the heating efficiency and making the cold air flow obtain sufficient heat.

[0033] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, a plurality of air outlets 56 are evenly distributed along the circumferential direction of the lower end of the air outlet section 51, and the air outlets 56 are used to connect the cooking cavity 11 and the air outlet channel 53. Preferably, the air outlets 56 are evenly distributed along the circumferential direction, and the air outlet channel 53 is connected to the cooking cavity 11 through the air outlets 56, so that the air outlet channel 53 can uniformly inject hot air into the cooking cavity 11 through the air outlets 56, avoiding the phenomenon of uneven heating of food in the cooking cavity 11.

[0034] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the total cross-sectional area of the air outlets 56 is equal to the total cross-sectional area of the air inlet of the air guide channel 54. Preferably, the total cross-sectional area of the air inlet of the air guide channel 54 is equal to the total cross-sectional area of the air outlets 56 (i.e., the size of the air inlet of the air guide assembly 5 is equal to the size of the air outlets 56), so that the air pressure at the air inlet of the air guide channel 54 is equal to the air pressure at the air outlets 56, preventing a significant pressure difference in the air guide assembly 5, effectively maintaining the stability of the airflow, ensuring that the airflow in the air guide assembly 5 is more stable, helping to reduce turbulence and vortex of the airflow in the air guide assembly 5, thereby reducing energy loss and noise.

[0035] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, the air guiding assembly 5 further comprises a flow guiding portion 57, which is arranged in the middle of the air guiding section 52 and spaced from the inner wall of the air guiding section 52 to form the air guiding passage 54. Optionally, the air guiding assembly 5 comprises an outer housing, which is divided into the air guiding section 52 and the air outlet section 51 from top to bottom. The flow guiding portion 57 is an independent component and arranged in the middle of the air guiding section 52. Optionally, the flow guiding portion 57 is connected to the upper end of the flow dividing portion 55, so that the cold air flow flowing from the top is evenly diffused to the air outlet passage 53. Optionally, the air guiding assembly 5 comprises a flow guiding outer housing and a flow guiding bottom housing. The flow guiding outer housing is divided into the air guiding section 52 and the air outlet section 51 from top to bottom. The flow guiding bottom housing is arranged on the lower end of the flow guiding outer housing (i.e. the lower end of the air outlet section 51). The middle of the flow guiding bottom housing is concave upward to form the flow dividing portion 55. The outer periphery of the flow dividing portion 55 is spaced from the inner wall of the flow dividing section to form the air outlet passage 53. The flow guiding portion 57 is connected to the upper end of the flow dividing portion 55. The flow guiding portion 57 is spaced from the inner wall of the air guiding section 52 to form the air guiding passage 54. The air guiding passage 54 and the air outlet passage 53 are arranged from top to bottom and communicate with each other. Optionally, the diameter of the flow guiding portion 57 decreases from top to bottom. Optionally, the flow guiding portion 57 is hemispherical or conical. Preferably, the flow guiding portion 57 is conical. Preferably, the central axis of the flow guiding portion 57, the central axis of the flow dividing portion 55 and the central axis of the air inlet of the air guiding passage 54 are collinear. After the cold air flow output by the fan assembly 2 flows into the air guiding passage 54, the cold air flow is evenly diffused to the air outlet passage 53 by the flow guiding portion 57. Then the cold air flow is heated into hot air flow by the heating assembly 3. The hot air flow is evenly injected into the cooking cavity 11 through the air outlet 56 of the air outlet passage 53 to uniformly heat the cooking cavity 11.

[0036] Further, the middle of the flow guiding bottom housing is concave upward to form the flow dividing portion 55, which causes the flow guiding bottom housing to form a downward groove covering the opening 12. Preferably, the lower end of the groove is covered with a tray to prevent the hot air flow containing oil from entering the groove and causing the groove to be contaminated with oil and difficult to clean. Optionally, the tray is flat to facilitate the user to reach into the cooking cavity 11 to clean the tray.

[0037] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, the fan assembly 2 comprises at least one centrifugal fan 21, and a gas conveying member 22 is connected to the exhaust port of the centrifugal fan 21, and the gas conveying member 22 is used to guide the airflow into the cooking cavity 11. Preferably, the gas conveying member 22 can be a gas conveying pipe, an interface, or the like, and the gas conveying member 22 is used to connect the exhaust port of the centrifugal fan 21 with the air inlet of the guide assembly 5. Optionally, the gas conveying member 22 is an arc-shaped gas conveying pipe, and the centrifugal fan 21 conveys the airflow to the guide assembly 5 through the arc-shaped gas conveying pipe. The arc-shaped gas conveying pipe is used to guide the cold airflow output by the centrifugal fan 21 to flow along a preset path, which helps to guide the cold airflow to the air inlet of the guide assembly 5 and improves the efficiency of the cold airflow entering the guide assembly 5. Optionally, the fan assembly 2 can further comprise a fan housing, and the centrifugal fan 21 is arranged inside the fan housing. The fan housing is arranged on the main body assembly 1, and the fan housing is provided with an air inlet in communication with the inside. The centrifugal fan 21 is in communication with the outside through the air inlet of the fan housing. Optionally, the number of the centrifugal fans 21 is two or more. Preferably, the centrifugal fans 21 are distributed at equal intervals in the circumferential direction around the central axis of the air inlet of the air guide channel 54, and the exhaust port of each centrifugal fan 21 is connected with an arc-shaped gas conveying pipe. The air inlet of the arc-shaped gas conveying pipe is in communication with the exhaust port of the centrifugal fan 21, the air outlets of the arc-shaped gas conveying pipes are in communication with each other, and the air outlets of the arc-shaped gas conveying pipes are in communication with the air inlet of the air guide channel 54. The arc-shaped gas conveying pipe is used to drive the exhaust port of the centrifugal fan 21 to stagger with each other, that is, the projection of the exhaust port of any two centrifugal fans 21 on a projection plane has no overlapping area, wherein the projection plane is a plane containing the central axis of the air inlet of the air guide channel 54. In this way, the arc-shaped gas conveying pipe is used to guide the cold airflow output by the centrifugal fan 21 to flow along a preset path, which avoids the airflow conflict and disorder caused by the direct opposite of the two centrifugal fans 21, thereby reducing the energy loss and improving the energy efficiency ratio of the fan.

[0038] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, one end of the main assembly 1 is provided with an opening 12, which is in communication with the cooking cavity 11. The cooking cavity 11 contains a frying basket 13. The frying basket 13 is connected to a cover plate 14 at one end close to the opening 12. The cover plate 14 is connected to the opening 12. The cover plate 14 is connected to a traction member 15 at one end away from the frying basket 13. Optionally, the traction member 15 can be a handle, a grip, a buckle, etc. In this embodiment, the user can push or pull the traction member 15 to drive the cover plate 14 to move the frying basket 13 along the opening 12, so that the frying basket 13 is contained in the cooking cavity 11 or extends out of the cooking cavity 11. In this embodiment, the cover plate 14 is connected to the opening 12, so that the cover plate 14 can close the opening 12 to prevent hot air from flowing out of the opening 12, avoid the user being scalded by hot air, and improve the safety of the equipment. Optionally, a food material bracket can be placed in the frying basket 13 to place food materials, prevent food materials from sticking to the frying basket 13 during cooking, or prevent uneven heating.

[0039] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the exhaust assembly 4 includes a hot air outlet 41, which is arranged at one end of the main assembly 1 away from the opening 12. An exhaust gap 42 is formed between the frying basket 13 and the inner wall of the cooking cavity 11, which communicates the hot air outlet 41 with the frying basket 13. Optionally, the hot air outlet 41 is arranged at one end of the main assembly 1 away from the opening 12, so that the hot air is discharged from the side of the air fryer away from the user, avoiding the user being scalded by hot air, and improving the safety of the equipment. In this embodiment, the hot air enters the frying basket 13 and contacts the food materials in the frying basket 13 to heat the food materials. Then, the hot air flows from the exhaust gap 42 to the hot air outlet 41, and from the hot air outlet 41 to the outside, effectively preventing the hot air from carrying oil to the heating assembly 3 and the fan assembly 2. Optionally, a filter screen structure can be arranged in the hot air outlet 41 to prevent external pollutants from entering the cooking cavity 11 through the hot air outlet 41.

[0040] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 Figure 2 Figure 3 Figure 4 Figure 5 Figure 2 Figure 3 Figure 4 Figure 5 Figure 2 Figure 3 Figure 4 Figure 5 Figure 2 Figure 3 Figure 4 Figure 5 Figure 2 Figure 3 Figure 4 Figure 5 Figure 2 Figure 3 Figure 4 Figure 5 FigureIn some embodiments, the number of centrifugal fans 21 is two, the two centrifugal fans 21 are distributed equidistantly in the circumferential direction, and each centrifugal fan 21 is connected with an arc-shaped air conveying pipe, the air inlet of the arc-shaped air conveying pipe is communicated with the air outlet of the centrifugal fan 21, the air outlets of a plurality of arc-shaped air conveying pipes are communicated with each other and with the air inlet of the air guide channel 54, the arc-shaped air conveying pipe is used to stagger the air outlets of the centrifugal fans 21 and guide the cold air flow output by the centrifugal fans 21 to flow along a preset path, so as to avoid air flow conflict and disorder when the two centrifugal fans 21 are directly opposite, reduce energy loss, improve the energy efficiency ratio of the fan, and help guide the cold air flow to the air inlet of the air guide channel 54. After the cold air flow flows into the air guide channel 54, the cold air flow is uniformly diffused to the air outlet channel 53 by the conical flow guide part 57, and the outer surface of the flow guide part 57 is parallel to the inner wall of the air guide section 52, so that the two sides of the air guide channel 54 are parallel to each other, effectively reducing the air resistance, vibration and noise in the air duct, and improving the overall reliability and stability of the system. The heating pipe 31 is wound on the flow dividing part 55 to increase the contact area and contact frequency of the heating pipe 31 and the cold air flow flowing through the air outlet channel 53, effectively improve the heating efficiency, so that the cold air flow obtains enough heat and is heated into hot air flow. The hot air flow is uniformly injected into the cooking cavity 11 through the air outlets 56 uniformly distributed on the lower end of the air outlet section 51 in the circumferential direction, avoiding the phenomenon that the food in the cooking cavity 11 is heated unevenly. The hot air flow enters the fryer basket 13 and contacts the food in the fryer basket 13 to heat the food. Then the hot air flow flows from the air gap 42 to the hot air outlet 41 and then to the outside from the hot air outlet 41, preventing the hot air flow from carrying oil to the heating assembly 3 or the fan assembly 2, effectively avoiding the problem of oil contamination of the heating assembly 3 or the fan assembly 2, and cleaning the air fryer without complex disassembly of the heating assembly 3 or the fan assembly 2, thereby optimizing the cleaning steps of the air fryer.
