Description

Technical Field

[0001] This utility model relates to the field of air fryers, specifically an air fryer exhaust structure. Background Technology

[0002] An air fryer is a kitchen appliance that heats and frys food by heating air and using a fan to create hot airflow. In existing technology, an air fryer includes a main body and an inner fryer compartment. A fan device is installed at the rear of the inner fryer compartment. This fan device includes a hot air fan that blows air into the inner fryer compartment to create a hot airflow for heating and frying, and a cooling fan that blows air into the main body compartment through air inlets and outlets on the outer casing to exchange heat with the outside of the main body. Regarding the exhaust air from the fan device, there are industry safety regulations. Besides ensuring that the air does not blow directly onto people, it is also required that when the air blown from the air fryer reaches a wall or furniture, the surface temperature of the wall or furniture after heating should not exceed 90 degrees Celsius to avoid the danger of overheating and causing a fire. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an exhaust structure for an air fryer.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] An air fryer exhaust structure includes a fan device arranged inside the main body of the fryer. The main body has an inner liner for housing the fryer body, and a cavity for accommodating the fan device is formed between the inner liner and the inner wall of the main body. The main body also has an exhaust vent, through which the fan device draws air to expel heat from inside the main body to the outside. An air guide hood is also installed on the main body to cover the exhaust vent, and the air guide hood has an air outlet facing the side of the main body. An air guide baffle is also arranged on the side of the air guide hood, extending towards the side of the main body and gradually tilting towards it. The air outlet is located between the air guide baffle and the wall of the main body.

[0006] The edge of the air guide baffle is bent toward the back of the main body to form an air guide ring wall.

[0007] The exhaust vent is located on the back of the main body of the machine.

[0008] The air guide cover is fixedly connected to the main body of the machine body via a mounting base plate.

[0009] One side of the mounting base plate extends in the same direction as the air guide baffle and its length and width are greater than those of the air guide baffle.

[0010] The air guide baffle and the air guide cover can be integrated as one piece or assembled separately.

[0011] The air outlet is equipped with a grille.

[0012] The receiving cavity is located on the back side of the inner liner. A vent is provided on the back wall of the inner liner to connect to the receiving cavity. The receiving cavity is divided into a hot air cavity, a heat dissipation cavity, and an electrical cavity. The hot air cavity is located behind the back wall of the inner liner, and a heating device is arranged within it near the vent. The heat dissipation cavity and the electrical cavity are arranged sequentially behind the hot air cavity. The fan device includes a motor, hot air fan blades, and heat dissipation fan blades. The hot air fan blades are located within the hot air cavity behind the heating device. The heat dissipation fan blades are located within the heat dissipation cavity. The motor is located within the electrical cavity, and its drive shaft passes sequentially through the heat dissipation fan blades and the hot air fan blades to achieve synchronous driving of the heat dissipation fan blades and the hot air fan blades. The hot air cavity and the heat dissipation cavity have openings on the same side, arranged side-by-side to form an air outlet. The air outlet and the exhaust port are perpendicularly distributed and connected by a guide channel that allows the airflow to bend.

[0013] The corner walls within the air guide channel are designed to be curved.

[0014] The air guide channel is located inside the air guide box.

[0015] The beneficial effects of this utility model are as follows: By setting up an air guide hood, the air outlet of this utility model is redirected so that the exhaust air blows towards the side space of the main body of the unit. Furthermore, by using the air guide baffle on the air guide hood that is inclined towards the main body of the unit, the air outlet of the air guide hood is guided to first contact the main body of the unit and then bounce back towards the side space of the main body of the unit. After being bounced and diffused by the main body of the unit, the hot air in the exhaust air can effectively contact the atmosphere and cool down. This further avoids the situation where the surface temperature of the exhaust air blows onto the wall or furniture and causes it to become too high. This ensures that the exhaust air of the air fryer fully complies with the industry's safety standards. Attached Figure Description

[0021] Reference Figure 1An air fryer is shown, comprising a main body 1, a fan device 2 and an inner liner 3 for mounting the fryer body inside the main body 1. The back of the inner liner 3 has a cavity 4 for accommodating the fan device 2, and a vent 31 on the back wall of the inner liner 3 connects to the cavity 4. The cavity 4 is divided into a hot air cavity 41, a heat dissipation cavity 42, and an electrical cavity 43. The hot air cavity 41 is located behind the back wall of the inner liner 3, and a heating element 5 is arranged within it near the vent 31. The heat dissipation cavity 42 and the electrical cavity 43 are arranged sequentially behind the hot air cavity 41. The fan device 2 includes a motor 21, a hot air fan blade 22, and a heat dissipation fan blade 23. The hot air fan blade 22 is located within the hot air cavity 41 behind the heating element 5. The heat dissipation fan blade 23 is located within the heat dissipation cavity 42. The motor 21 is located within the electrical cavity 43, and its drive shaft passes sequentially through the heat dissipation fan blade 23 and the hot air fan blade 22 to achieve synchronous driving of the heat dissipation fan blade 23 and the hot air fan blade 22.

[0022] The hot air chamber 41 and the heat dissipation chamber 42 have openings on the same side, and the two openings are arranged side by side to form an air outlet 44. The back of the body is provided with an exhaust port 11. The air outlet 44 and the exhaust port 11 are vertically distributed and connected by an air guide box 6. The air guide box 6 is provided with an air guide channel 61 that can realize the deflection of the airflow. The back of the main body 1 is also equipped with an air guide cover 7 to cover the exhaust port 11. The side of the air guide cover 7 facing the side of the body has an air outlet opening 71 to realize the secondary deflection of the airflow. In order to prevent foreign objects from entering through the air outlet opening 71, a grille is provided. At this time, the air guide box 6 and the air guide cover 7 form an S-shaped meandering air duct, so that the air from the hot air chamber 41 and the heat dissipation chamber 42 can smoothly reach the air outlet opening 71 for lateral air outlet. The side of the air guide cover 7 is also provided with an air guide baffle 72. The air guide baffle 72 extends toward the side of the main body 1 and gradually tilts toward the back of the main body 1. The air outlet 71 is located between the air guide baffle 72 and the back wall of the main body. The air guide baffle 72 further guides the air outlet direction of the air outlet 71. The tilted air guide baffle 72 causes the air outlet 71 to first contact the back of the main body 1 and then bounce back to the side space of the main body 1 for air outlet.

[0023] like Figure 2 The edge of the air guide baffle 72 is bent towards the back of the main body 1 to form an air guide ring wall 74. The air guide ring wall 74 can more comprehensively guide the air out of the air outlet 71 to contact the back of the main body 1 first. The air guide cover 7 is fixedly connected to the back of the main body 1 through the mounting base plate 73. One side of the mounting base plate 73 extends in the same direction as the air guide baffle 72 and its length and width are greater than those of the air guide baffle 72. When the air out of the air outlet 71 is guided by the air guide baffle 72 to blow towards the back of the main body 1, the exhaust hot air will blow directly onto the mounting base plate 73 covering the back wall of the main body 1. The hot air is then deflected by the mounting base plate 73 and discharged into the side space.

[0024] As a preferred option, the air guide baffle 72 and the air guide cover 7 can be integrated as one piece or assembled separately, depending on the production situation.

[0025] like Figure 3 , Figure 4 As shown, the corner wall of the air guide channel 61 is set as an arc surface 62, and the corner of the air guide channel 61 is directly opposite the air outlet 44, so that the airflow discharged from the air outlet 44 can turn smoothly.

[0026] This invention guides the exhaust air from the hot air chamber 41 and the heat dissipation chamber 42 to the back of the main body 1 through the air guide box 6, making it difficult for the exhaust air of the air fryer to blow onto the human body. According to the user's habit of placing the air fryer, the side space is larger than the back space. Therefore, the exhaust air is redirected twice by the air guide cover 7 so that the exhaust air blows into the side space of the main body 1. Furthermore, the air guide baffle 72 on the air guide cover 7, which is inclined towards the back of the main body 1, guides the exhaust air of the air guide cover 7 to first contact the back of the main body 1 and then bounce back to the side space of the main body 1. After being bounced and diffused by the back of the main body 1, the hot air in the exhaust air can effectively contact the atmosphere and cool down, further avoiding the situation where the surface temperature of the exhaust air blows onto the wall or furniture and causes it to become too high. With the above structure, the exhaust air of the air fryer fully complies with the industry's safety standards.
