An upright air fryer

Abstract

This utility model discloses a vertical air fryer, belonging to the field of air fryers. It includes a main body structure, inside which a grilling mechanism is installed. Above the grilling mechanism, a baking mechanism is installed inside the main body structure. The baking mechanism includes a drive motor, with an upper fan blade fixedly installed in the middle of the drive motor, and a lower fan blade fixedly installed at the lower end of the drive motor below the upper fan blade. The key technical point is that by combining the upper and lower fan blades into a coaxial double-fan blade structure, the upper fan blade, located at the upper end of the heating element, draws external airflow into the device. The lower fan blade, located in the middle of the heating element, utilizes the principle that a smaller heating element surface area results in higher thermal efficiency. When the lower fan blade rotates, the surrounding airflow blows heat from top to bottom towards the grilling mechanism area. Furthermore, the airflow bounces off the bottom of the grilling mechanism area and rises at its edge, preventing heat accumulation and improving heating uniformity.

Description

Technical Field

[0001] This utility model relates to the field of vertical air fryer. Background Technology

[0002] An air fryer is a cooking appliance that uses rapidly circulating hot air inside to heat and bake food. It mainly uses air instead of the hot oil in a frying pan to cook the food. At the same time, the hot air blows away the moisture on the surface of the food, giving the food an effect similar to deep-frying. It can also be understood as using high-temperature "air" as a medium to "fry" food. The control methods of air fryers on the market are mainly knob type and LCD touch screen type.

[0003] Air fryers come in a variety of styles, with the upright air fryer being one of the most popular. However, in existing upright air fryers, the airflow blown by the fan blades accumulates on the opposite side of the heating element, resulting in a lack of convection and uneven heat distribution inside the fryer. The rear part of the grilling zone is prone to charring. Furthermore, during use, the fan blades continuously blow out external airflow, preventing heat from staying in the front of the grilling zone, leading to significant heat loss. Therefore, we propose an upright air fryer. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a vertical air fryer. By combining the upper and lower fan blades into a coaxial double-fan blade structure, the upper fan blade is located at the upper end of the heating tube, drawing external airflow into the interior of the device. The lower fan blade is located in the middle of the heating tube. Based on the principle that the smaller the surface area of ​​the heating tube, the higher the thermal efficiency, the surrounding airflow when the lower fan blade rotates blows heat from top to bottom to the grilling area. The airflow bounces at the bottom of the grilling area and rises at its edge, avoiding heat accumulation and improving the uniformity of heating.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A vertical air fryer includes a main body, a grilling mechanism installed inside the main body, and a baking mechanism installed above the grilling mechanism inside the main body.

[0007] The baking mechanism includes a drive motor, with an upper fan blade fixedly installed in the middle of the drive motor. A lower fan blade is fixedly installed at the lower end of the drive motor, located below the upper fan blade. A heating element is fixedly installed on the outer side of the lower fan blade. When set up, the drive motor and the heating element are stacked in the height direction. The heating element and the blades of the lower fan blade are almost at the same height, which is conducive to the air circulation when baking food and makes the food heat more evenly.

[0008] Furthermore, the main structure includes a frame, with an air intake hole at the lower end of the frame, a side wall fixedly installed at the outer end of the frame, an exhaust hole in the middle of the side wall, a control panel fixedly installed in the middle of the right end of the frame, a top cover fixedly installed at the upper end of the frame, a partition fixedly installed in the middle of the frame, and a vent hole at the rear end of the frame. By opening the air intake hole at the bottom of the frame, when the drive motor is running, airflow flows from bottom to top, while the exhaust hole assists in air intake from both sides of the device, which is beneficial for the internal airflow and heat dissipation during the use of the device.

[0009] Furthermore, the barbecue mechanism includes a barbecue oven, a barbecue rack is movably installed inside the barbecue oven, a protective panel is fixedly installed on the outer end of the barbecue oven, a handle is fixedly installed in the middle of the outer end of the protective panel, the protective panel, the side wall and the rear end of the frame are made of the same material, therefore the outer end of the device is made of a high-polymer material with good heat resistance.

[0010] Furthermore, the drive motor is fixedly installed at the inner end of the frame. The upper and lower fan blades have different fan blade structures. The upper fan blade is connected to the transmission end of the drive motor, and the lower fan blade is also connected to the transmission end of the drive motor. The upper and lower fan blades are combined to form a coaxial double fan blade structure. The upper fan blade is located at the upper end of the heating tube, drawing external airflow into the interior of the device. The lower fan blade is located in the middle of the heating tube. Based on the principle that the smaller the surface area of ​​the heating tube, the higher the thermal efficiency, the surrounding airflow when the lower fan blade rotates blows heat from top to bottom into the grilling mechanism area. The airflow bounces back at the bottom of the grilling mechanism area and rises at its edge, avoiding heat accumulation and improving the uniformity of heating.

[0011] Furthermore, the exhaust holes are equidistantly distributed in the middle of the sidewall, and the air intake holes and exhaust holes have the same structure.

[0012] Furthermore, the barbecue oven is movably installed inside the frame, and there are two barbecue ovens in total. The barbecue rack and the barbecue oven are detachable.

[0013] Furthermore, the outer end of the protective panel has an arc-shaped structure, and the handle has an inverted L-shaped structure.

[0014] Furthermore, there are two heating elements, which are fixedly installed at the upper end of the partition and at the bottom of the inner end of the frame.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By combining the upper and lower fan blades into a coaxial double-fan blade structure, the upper fan blade is at the top of the heating tube, drawing external airflow into the interior of the device. The lower fan blade is in the middle of the heating tube. Based on the principle that the smaller the surface area of ​​the heating tube, the higher the thermal efficiency, the surrounding airflow when the lower fan blade rotates blows heat from top to bottom to the grilling mechanism area. The airflow bounces at the bottom of the grilling mechanism area and rises at its edge, avoiding heat accumulation and improving the uniformity of heating.

[0017] 2. By opening the air intake hole at the bottom of the frame, when the drive motor is running, the airflow flows from bottom to top. At the same time, the exhaust hole assists the air intake from both sides of the device, which is conducive to the flow of internal air and heat dissipation when the device is in use. The side wall, together with the top cover and the rear end of the frame, forms the shell of the device. Therefore, the exhaust hole provided on the side of the side wall allows the heat to pass through the bottom of the food, and the airflow bounces off the bottom of the grilling mechanism area and rises at the edge, and is discharged from the exhaust hole.

[0027] Reference Figure 1-6 As shown, a vertical air fryer is provided in a preferred embodiment of the present invention, including a main body 1, a grilling mechanism 2 installed inside the main body 1, and a baking mechanism 3 installed above the grilling mechanism 2 inside the main body 1.

[0028] The baking mechanism 3 includes a drive motor 301. An upper fan blade 302 is fixedly installed in the middle of the drive motor 301. A lower fan blade 303 is fixedly installed at the lower end of the drive motor 301, located below the upper fan blade 302. A heating element 304 is fixedly installed on the outer side of the lower fan blade 303. When set up, the drive motor 301 and the heating element 304 are stacked in the height direction. The blades of the heating element 304 and the lower fan blade 303 are almost at the same height, which is conducive to the air circulation when baking food and makes the food heat more evenly.

[0029] The main structure 1 includes a frame 101. A suction hole 102 is provided at the lower end of the frame 101. A side wall 103 is fixedly installed at the outer end of the frame 101. An air inlet 104 is provided in the middle of the side wall 103. A control panel 105 is fixedly installed in the middle of the right end of the frame 101. A top cover 106 is fixedly installed at the upper end of the frame 101. A partition 107 is fixedly installed in the middle of the frame 101. An exhaust hole 108 is provided at the rear end of the frame 101. The suction hole 102 is located at the bottom of the frame 101. When the drive motor 301 is running, the airflow flows from bottom to top. At the same time, the air inlet 104 assists in air intake from both sides of the device, which is conducive to the flow of internal air and heat dissipation when the device is in use.

[0030] The barbecue mechanism 2 includes a barbecue oven 201, a barbecue rack 202 is movably installed inside the barbecue oven 201, a protective panel 203 is fixedly installed on the outer end of the barbecue oven 201, and a handle 204 is fixedly installed in the middle of the outer end of the protective panel 203. The protective panel 203, the side wall 103 and the rear end of the frame 101 are made of the same material. Therefore, the outer shell of the device is made of a high-polymer material with good heat resistance.

[0031] The drive motor 301 is fixedly installed at the inner end of the frame 101. The upper fan blade 302 and the lower fan blade 303 have the same structure. The upper fan blade 302 is connected to the transmission end of the drive motor 301, and the lower fan blade 303 is connected to the transmission end of the drive motor 301. The upper fan blade 302 and the lower fan blade 303 are combined to form a coaxial double fan blade structure. The upper fan blade 302 is at the upper end of the heating tube 304 and draws away the external airflow. The lower fan blade 303 is in the middle of the heating tube 304. According to the principle that the smaller the surface area of ​​the heating tube 304, the higher the thermal efficiency, the heat is blown from top to bottom to the grilling mechanism 2 area by the surrounding airflow when the lower fan blade 303 rotates. The airflow bounces at the bottom of the grilling mechanism 2 area and rises at its edge, avoiding heat accumulation and improving the uniformity of heating.

[0032] The air inlets 104 are evenly distributed in the middle of the side wall 103. The air intake 102 and the air inlets 104 have the same structure. The side wall 103, together with the top cover 106 and the rear end of the frame 101, forms the housing of the device. Therefore, the air inlets 104 provided on the side of the side wall 103 allow the airflow to bounce off the bottom of the grilling mechanism 2 area after the heat passes through the bottom of the food and rise at the edge. Then, the cold air entering from the air inlets 104 assists in heat dissipation.

[0033] The barbecue oven 201 is movably installed inside the frame 101. There are two barbecue ovens 201. The barbecue rack 202 and the barbecue oven 201 are detachable structures. Making the barbecue rack 202 and the barbecue oven 201 detachable structures facilitates the removal of food from inside the barbecue oven 201 and also makes it easier to clean the barbecue oven 201 and the barbecue rack 202.

[0034] The outer end of the protective panel 203 is arc-shaped, and the handle 204 is an inverted L-shaped structure. The arc-shaped protective panel 203 makes the outer shell structure of the device fit smoothly.

[0035] There are two heating elements 304. The heating elements 304 are fixedly installed on the upper end of the partition 107 and the bottom of the inner end of the frame 101. Since the device is a double-layer vertical fryer, it is divided into two independent areas by the partition 107. The heating elements 304 and other components are also the same number of two.

[0036] Specific implementation process: This utility model is a vertical air fryer. In its design, the drive motor 301 and heating element 304 are stacked vertically. The blades of the heating element 304 and the lower fan blade 303 are almost at the same height, which facilitates airflow during cooking and ensures more even heating. The upper fan blade 302 and lower fan blade 303 are combined into a coaxial double-blade structure. The upper fan blade 302 is located above the heating element 304, drawing away external airflow. The lower fan blade 303 is located in the middle of the heating element 304. Based on the principle that a smaller surface area of ​​the heating element 304 results in higher thermal efficiency, the surrounding airflow from the lower fan blade 303 dissipates heat from top to bottom. The airflow is blown into the grilling mechanism 2 area, and the airflow bounces at the bottom of the grilling mechanism 2 area and rises at its edge to avoid heat accumulation and improve the uniformity of heating. Then, the suction hole 102 is opened at the bottom of the frame 101. When the drive motor 301 is running, the airflow flows from bottom to top. At the same time, the air inlet 104 assists in air intake from both sides of the device, which is conducive to the flow of internal air and heat dissipation when the device is in use. The device forms an outer shell by the side wall 103, the top cover 106, and the rear end of the frame 101. Therefore, the air inlet 104 provided on the side of the side wall 103 allows the airflow to bounce from the bottom of the grilling mechanism 2 area after the heat passes through the bottom of the food and rises at the edge. Then, the cold air entering from the air inlet 104 assists in heat dissipation.
