Description

Technical Field

[0001] This utility model relates to the technical field of air fryers, specifically to an air fryer preheating structure. 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.

[0003] The key feature of the air fryer disclosed in publication number "CN220089275U" is that a storage chamber for preheating food is provided on the top side of the main body of the air fryer. Specifically, the storage chamber is located on the top side of the main body and is connected to the heat insulation layer in the groove above the top of the fryer body through an air guide channel. The hot air vent of the storage chamber is connected to the air guide channel and is located on the top side of the main body or the top of the storage chamber. Heat is provided to the storage chamber and then discharged. The groove of the heat insulation layer is equipped with a metal centrifugal fan and a heating element. The metal centrifugal fan is connected to the motor shaft of the motor inside the heat insulation layer. The air outlet on the side of the main body is connected to the storage chamber. The storage chamber is integrated with the main body, which facilitates the use of residual heat from the air guide channel to heat the storage chamber.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] With the increasing popularity and widespread use of air fryers, many users will put food taken from the refrigerator directly into the air fryer for baking. However, food that has not been preheated will have its surface cooked while the center remains undercooked, which will affect the baking effect. Utility Model Content

[0006] The purpose of this invention is to provide an air fryer preheating structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An air fryer preheating structure includes a pot body, a fan, and a heating element. The fan and heating element are both fixedly installed inside the pot body. A storage chamber is provided at the top of the pot body. A metal box is installed inside the storage chamber. Two support rods for supporting the metal box are fixedly connected to the inner wall of the storage chamber. A pressure relief pipe is fixedly connected to the inner wall of the pot body. A transmission pipe is fixedly connected to the top of the pressure relief pipe. One end of the transmission pipe extends into the interior of the storage chamber and is fixedly connected to an exhaust housing through a one-way pressure valve. A reciprocating mechanism is provided inside the storage chamber.

[0009] The reciprocating mechanism includes a motor fixedly installed on one side of the pot body. The output end of the motor extends through the interior of the storage chamber and is fixedly connected to a lead screw. A transmission block is driven to the surface of the lead screw. A support block is fixedly connected to the transmission block. A swing mechanism is provided at the connection between the support block and the exhaust housing.

[0010] Preferably, the swing mechanism includes a rotating rod fixedly connected to one side of the exhaust housing, a rotating hole for cooperating with the rotating rod is provided on one side of the support block, a gear is fixedly connected to one end of the rotating rod, a toothed plate for cooperating with the gear is fixedly connected to the inner wall of the storage chamber, a torsion spring is sleeved on the surface of the rotating rod, one end of the torsion spring is fixedly connected to one side of the gear, and the other end of the torsion spring is fixedly connected to one side of the exhaust housing.

[0011] Preferably, the number of toothed plates is several, and they are evenly distributed on the inner wall of the storage chamber.

[0012] Preferably, a sliding block is fixedly connected to one side of the transmission block, and a sliding groove is provided on the inner wall of the storage chamber to cooperate with the sliding block.

[0013] Preferably, one end of the lead screw is provided with a bearing, and is rotatably connected to the inner wall of the storage chamber through the bearing.

[0014] Preferably, the top of the pot body is hinged to a sealing cover, and a handle is fixedly connected to the top of the sealing cover.

[0015] Preferably, the top of the sealing cover has four vent holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, by setting up a reciprocating mechanism, enables the drying of food by placing food taken from the refrigerator into a metal box in the storage compartment, followed by placing food to be dried into the pot, activating the heating element and fan to generate hot air circulation for drying. As the air inside the pot heats up, the internal gas also rises. When the gas pressure exceeds the limit of the one-way pressure valve, the gas enters the transmission pipe through the pressure relief pipe and is finally blown upwards from the exhaust shell. The hot air heats the bottom of the metal box, thereby preheating the food in the metal box. At the same time, the motor drives the lead screw to rotate, which in turn drives the transmission block, causing the transmission block to reciprocate along the trajectory of the sliding block and sliding groove. The support block and the exhaust shell reciprocate synchronously with the transmission block, continuously changing the position of the hot air blown out by the exhaust shell, uniformly heating the bottom of the metal box, and further improving the uniformity of preheating.

[0018] 2. By setting up a swing mechanism, this utility model can move the exhaust housing back and forth while the support block moves it. At the same time, the gear will also move synchronously. When the gear contacts the tooth plate, it will drive the rotating rod and the exhaust housing to rotate around the rotating rod. When the gear moves to the point where it does not contact the tooth plate, the torque generated by the torsion spring will drive the exhaust housing to reset, so that the exhaust housing can swing and blow hot air to the bottom of the metal box, further improving the preheating effect of food.

[0019] In this invention, the reciprocating mechanism can change the position of the hot air blown out of the exhaust shell, so as to heat the bottom of the metal box evenly and improve the uniformity of preheating. At the same time, the swinging mechanism allows the exhaust shell to swing and blow hot air out of the bottom of the metal box, which further improves the preheating effect of food and solves the problem that food that has not been preheated will be baked on the surface but raw in the center, which will affect the baking effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 This utility model provides a technical solution:

[0028] Example 1:

[0029] An air fryer preheating structure includes a pot body 1, a fan 2, and a heating element 3. The fan 2 and the heating element 3 are both fixedly installed inside the pot body 1. A storage chamber 4 is opened at the top of the pot body 1. A metal box 5 is installed inside the storage chamber 4. Two support rods 6 for supporting the metal box 5 are fixedly connected to the inner wall of the storage chamber 4. A pressure relief pipe 23 is fixedly connected to the inner wall of the pot body 1. A transmission pipe 7 is fixedly connected to the top of the pressure relief pipe 23. One end of the transmission pipe 7 extends into the interior of the storage chamber 4 and is fixedly connected to an exhaust housing 8 through a one-way pressure valve. A reciprocating mechanism is installed inside the storage chamber 4.

[0030] The reciprocating mechanism includes a motor 9 fixedly installed on one side of the pot body 1. The output end of the motor 9 extends through the interior of the storage chamber 4 and is fixedly connected to a lead screw 10. A transmission block 11 is connected to the surface of the lead screw 10. A support block 12 is fixedly connected to the transmission block 11. A swing mechanism is provided at the connection between the support block 12 and the exhaust housing 8.

[0031] In this embodiment, considering that unheated food will have a cooked surface but an undercooked center, affecting the baking effect, a reciprocating mechanism is used. Food taken from the refrigerator is placed in the metal box 5 inside the storage compartment 4, and then the food to be dried is placed inside the pot body 1. Activating the heating element 3 and the fan 2 generates hot air circulation to dry the food. As the air inside the pot body 1 heats up, the internal gas rises. When the gas pressure exceeds the limit of the one-way pressure valve, the gas enters the transmission pipe 7 through the pressure relief pipe 23. The hot air is then blown upwards from the exhaust housing 8, heating the bottom of the metal box 5 and preheating the food inside. At the same time, the motor 9 drives the lead screw 10 to rotate. As the lead screw 10 rotates, it drives the transmission block 11, causing the transmission block 11 to reciprocate along the trajectory of the sliding block 18 and the sliding groove 24. The support block 12 and the exhaust housing 8 reciprocate synchronously with the transmission block 11, constantly changing the position of the hot air blown out by the exhaust housing 8, so as to evenly heat the bottom of the metal box 5 and further improve the uniformity of preheating.

[0032] It should be noted that the transmission pipe 7 is a rubber hose that can be bent and stretched.

[0033] A sliding block 18 is fixedly connected to one side of the transmission block 11, and a sliding groove 24 that cooperates with the sliding block 18 is provided on the inner wall of the storage chamber 4.

[0034] In this embodiment, by setting the sliding block 18 and the sliding groove 24, when the lead screw 10 drives the transmission block 11, the transmission block 11, the support block 12 and the exhaust housing 8 and other structures can only move along the trajectory of the sliding block 18 and the sliding groove 24, thereby improving their stability during movement.

[0035] One end of the lead screw 10 is provided with a bearing 19, and is rotatably connected to the inner wall of the storage chamber 4 through the bearing 19.

[0036] In this embodiment, by setting the bearing 19, the lead screw 10 can be supported, and the lead screw 10 can only rotate around the bearing 19, thereby improving the smoothness and stability of its rotation process.

[0037] A sealing cover 20 is hinged to the top of the pot body 1, and a handle 21 is fixedly connected to the top of the sealing cover 20.

[0038] In this embodiment, by providing a sealing cover 20, the heat can be prevented from escaping rapidly from the storage chamber 4, thereby further improving the preheating effect.

[0039] The top of the sealing cover 20 has four vent holes 22.

[0040] In this embodiment, by providing a vent hole 22, air can be slowly released through the vent hole 22 after the sealing cover 20 is placed on the storage chamber 4, thereby achieving the effect of depressurization.

[0041] Example 2:

[0042] The swing mechanism includes a rotating rod 13 fixedly connected to one side of the exhaust housing 8. A rotating hole 14 that cooperates with the rotating rod 13 is opened on one side of the support block 12. A gear 15 is fixedly connected to one end of the rotating rod 13. A toothed plate 16 that cooperates with the gear 15 is fixedly connected to the inner wall of the storage chamber 4. A torsion spring 17 is sleeved on the surface of the rotating rod 13. One end of the torsion spring 17 is fixedly connected to one side of the gear 15, and the other end of the torsion spring 17 is fixedly connected to one side of the exhaust housing 8.

[0043] In this embodiment, by setting a swing mechanism, the gear 15 can move synchronously while the support block 12 drives the exhaust housing 8 to move back and forth. When the gear 15 contacts the toothed plate 16, it will drive the rotating rod 13 and the exhaust housing 8 to rotate around the rotating rod 13. When the gear 15 moves to a point where it does not contact the toothed plate 16, the torque generated by the torsion spring 17 will drive the exhaust housing 8 to reset, so that the exhaust housing 8 can swing and blow hot air out of the bottom of the metal box 5, further improving the effect of food preheating.

[0044] The number of toothed plates 16 is several, and they are evenly distributed on the inner wall of the storage chamber 4.

[0045] In this embodiment, by setting toothed plates 16, multiple toothed plates 16 can be set so that when the gear 15 contacts the toothed plate 16 once, it can drive the exhaust housing 8 to swing around the rotating rod 13 once, thereby achieving the effect of intermittently swinging the exhaust housing 8.

[0046] Working principle: The user places food taken from the refrigerator into the metal box 5 in the storage compartment 4, and then places the food to be dried into the pot body 1. By turning on the heating element 3 and the fan 2, hot air circulation is generated to dry the food. As the air inside the pot body 1 is heated, the internal gas will also rise. When the gas pressure is greater than the limit of the one-way pressure valve, the gas will enter the transmission pipe 7 through the pressure relief pipe 23 and finally be blown upward from the exhaust shell 8. The hot air will heat the bottom of the metal box 5, thereby preheating the food in the metal box 5. At the same time, the motor 9 will drive the lead screw 10 to rotate. As the lead screw 10 rotates, it will drive the transmission block 11, causing the transmission block 11 to move back and forth along the trajectory of the sliding block 18 and the sliding groove 24. The support block 12 and the exhaust shell 8 will move back and forth synchronously with the transmission block 11, constantly changing the position of the hot air blown out of the exhaust shell 8, so as to evenly heat the bottom of the metal box 5 and further improve the uniformity of preheating.

[0047] At the same time, as the support block 12 drives the exhaust housing 8 to move back and forth, the gear 15 will also move synchronously. When the gear 15 contacts the toothed plate 16, it will drive the rotating rod 13 and the exhaust housing 8 to rotate around the rotating rod 13. When the gear 15 moves to a point where it does not contact the toothed plate 16, the torque generated by the torsion spring 17 will drive the exhaust housing 8 to reset, so that the exhaust housing 8 can swing and blow hot air out of the bottom of the metal box 5, further improving the effect of food preheating.

[0048] It should be noted that the fan 2, the heating element 3 and the motor 9 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Furthermore, the specific composition and principle of the power supply of the fan 2, the heating element 3 and the motor 9 are clear to those skilled in the art, and therefore will not be described in detail.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
