Description

Technical Field

[0001] This utility model belongs to the field of cooking appliances, specifically relating to an air fryer. Background Technology

[0002] An air fryer is a cooking appliance that uses hot air to bake food. Due to its low-oil and low-fat cooking characteristics, it has gradually gained popularity among consumers in recent years. When using an air fryer, food is heated by hot air and cooked. The moisture in the food is heated and forms steam. To prevent this steam from affecting the dehydration of the food inside the cooking chamber, an exhaust vent is usually installed to expel the steam. However, current air fryer exhaust vents only have two states: open and closed. When the vent is open, the exhaust direction is fixed, continuously expelling hot air to the same location. This causes concentrated heat to be applied to furniture, walls, etc., directly opposite the exhaust vent, resulting in damage. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an air fryer that solves the problem of overheating and damage to furniture and walls directly facing the exhaust port due to the fixed exhaust direction of the air fryer's steam exhaust port.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: An air fryer includes a body and a head. The body has a cooking cavity, and the head is located on top of the body to cover the cooking cavity. The head has an exhaust assembly, which includes a mounting frame with an exhaust port, a guide plate for opening and closing the exhaust port, and a drive motor. The exhaust port is connected to the cooking cavity. The two ends of the guide plate are rotatably connected to the mounting frame via a rotating shaft. The drive motor is connected to the rotating shaft, and the guide plate rotates under the drive of the drive motor to adjust the air outlet angle of the exhaust port. This technical solution has the following technical effects: This invention sets up an exhaust assembly with a mounting frame, a guide plate, and a drive motor working together. During the initial cooking process, the drive motor controls the guide plate to rotate to the position of closing the exhaust vent, confining all the hot air within the cooking chamber and causing the temperature inside the chamber to rise rapidly for quick food cooking. Later in the cooking process, the drive motor controls the guide plate to rotate and open the exhaust vent, allowing some of the hot air inside the cooking chamber to escape. The outward-flowing hot air also carries away water vapor and oil evaporated from the food inside the cooking chamber, creating a caramelized layer on the surface of the food and improving its texture. Because the rotation of the air guide plate is controlled by a drive motor, during cooking, the drive motor can control the air guide plate to continuously swing, thereby constantly adjusting the air outlet angle. By sweeping the air up and down, it achieves uniform airflow and avoids the exhaust vent continuously expelling hot air to the same location, which would cause concentrated heat damage to furniture, walls, etc., directly opposite the exhaust vent. It also reduces heat accumulation near the exhaust vent. Furthermore, the drive motor drives the air guide plate to rotate, making the size of the exhaust vent controllable. By adjusting the size of the exhaust vent, the humidity and heating rate inside the cooking cavity can be adjusted, which can accommodate the different dehydration and degreasing needs of different ingredients, thereby improving the cooked taste of the ingredients.

[0005] In the aforementioned air fryer, multiple air guide plates are provided, and adjacent air guide plates are connected by connecting rods so that all air guide plates rotate together under the drive of the connecting rods. A drive motor is connected to one of the multiple air guide plates. The multiple air guide plates improve the adjustment accuracy of the air guide plates for the exhaust vents, reduce the space occupied by the air guide plates during rotation, and the connecting rods enable synchronous rotation of the air guide plates, allowing a single drive motor to drive all air guide plates to rotate synchronously, thus reducing the size of the exhaust assembly.

[0006] In the aforementioned air fryer, the end of the air guide plate is equipped with a drive shaft arranged parallel to the rotating shaft. The two ends of a connecting rod are rotatably connected to the drive shafts of two adjacent air guide plates, causing the two adjacent air guide plates to move in tandem. When one air guide plate rotates, the drive shaft swings around the rotating shaft, and the connecting rod drives the drive shafts on the adjacent air guide plates to swing together, causing the two adjacent air guide plates to rotate by the same angle. The structure is simple and reliable.

[0007] In the aforementioned air fryer, the connecting rod includes a rod body and C-shaped retaining rings at both ends of the rod body. The C-shaped retaining rings are engaged with the drive shaft for rotatable connection. By engaging the C-shaped retaining rings with the drive shaft, the connecting rod can be rotatably connected to the drive shaft, facilitating the installation and disassembly of the connecting rod. Furthermore, if the connecting rod is damaged, it can be repaired or replaced separately.

[0008] In the aforementioned air fryer, the rod body is provided with reinforcing ribs that protrude from the surface of the rod body and extend along the axial direction of the rod body to enhance the strength of the rod body and prevent the rod body from breaking.

[0009] In the aforementioned air fryer, the connecting rod is located outside the mounting frame. The mounting frame, on the side away from the motor, has an arc-shaped groove to allow the drive shaft to pass through. The drive shaft passes through the groove and exits the mounting frame to connect with the connecting rod. By placing the connecting rod outside the mounting frame, when the air guide plate closes the exhaust port, the connecting rod can be prevented from affecting the air guide plate's closing effect on the exhaust port, thus preventing air leakage between the side of the air guide plate and the mounting frame.

[0010] In the aforementioned air fryer, the mounting frame is also provided with pivot holes for the rotating shaft to pass through, and the pivot holes corresponding to the same guide plate are higher than the highest point of the slide groove. The fact that the pivot holes for mounting the same guide plate are higher than the highest point of the slide groove for mounting the same guide plate can prevent the end of the air guide plate with the connecting rod from locking itself during rotation, ensuring smooth rotation of the air guide plate.

[0011] In the aforementioned air fryer, the mounting frame is equipped with sealing ribs. When the air guide plate closes the exhaust port, both the upper and lower ends of the air guide plate abut against the sealing ribs. When the air guide plate closes the exhaust port, both the upper and lower sides of the air guide plate abut against the sealing ribs to prevent air leakage from the upper and lower sides of the air guide plate and improve the closing effect of the air guide plate on the exhaust port.

[0012] In the aforementioned air fryer, the mounting frame includes a detachably connected front frame and a rear frame. The front and rear frames are locked together to form a pivot hole for accommodating a rotating shaft. The fryer head includes a housing with mounting holes and a top cover located inside the housing. The rear frame is integrally mounted on the top cover, and the front frame passes through the mounting hole. The semi-holes on the front and rear frames form the pivot hole for accommodating the rotating shaft, enabling the installation and positioning of the air guide plate. The rear frame is integrally mounted on the top cover to reduce assembly steps, and the front frame passes through the mounting hole to communicate with the outside environment. The structure is simple and easy to assemble.

[0013] In the aforementioned air fryer, a mounting post is provided on the rear frame, and a drive motor is locked onto the mounting post. The output shaft of the drive motor is keyed to the end of a rotating shaft for linkage with the rotating shaft. By placing the mounting post on the rear frame, which is integrally formed with the rear cover, the stability of the drive motor can be improved.

[0014] The features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0017] This utility model proposes an air fryer, including a body and a head. The body has a cooking cavity, and the head is located on top of the body to cover the cooking cavity. The head has an exhaust assembly, which includes a mounting frame with an exhaust port, a guide plate for opening and closing the exhaust port, and a drive motor. The exhaust port is connected to the cooking cavity. The two ends of the guide plate are rotatably connected to the mounting frame via a rotating shaft. The drive motor is connected to the rotating shaft, and the guide plate rotates under the drive of the drive motor to adjust the air outlet angle of the exhaust port. This invention sets up an exhaust assembly with a mounting frame, a guide plate, and a drive motor working together. During the initial cooking process, the drive motor controls the guide plate to rotate to the position of closing the exhaust vent, confining all the hot air within the cooking chamber and causing the temperature inside the chamber to rise rapidly for quick food cooking. Later in the cooking process, the drive motor controls the guide plate to rotate and open the exhaust vent, allowing some of the hot air inside the cooking chamber to escape. The outward-flowing hot air also carries away water vapor and oil evaporated from the food inside the cooking chamber, creating a caramelized layer on the surface of the food and improving its texture. Because the rotation of the air guide plate is controlled by a drive motor, during cooking, the drive motor can control the air guide plate to continuously swing, thereby constantly adjusting the air outlet angle. By sweeping the air up and down, it achieves uniform airflow and avoids the exhaust vent continuously expelling hot air to the same location, which would cause concentrated heat damage to furniture, walls, etc., directly opposite the exhaust vent. It also reduces heat accumulation near the exhaust vent. Furthermore, the drive motor drives the air guide plate to rotate, making the size of the exhaust vent controllable. By adjusting the size of the exhaust vent, the humidity and heating rate inside the cooking cavity can be adjusted, which can accommodate the different dehydration and degreasing needs of different ingredients, thereby improving the cooked taste of the ingredients.

Example 1

[0023] An air fryer, such as Figures 1 to 9 As shown, the device includes a body 100 and a head 200. The body 100 has a cooking cavity, and the head 200 is located on top of the body 100 to cover the cooking cavity. An exhaust assembly 300 is provided on the head 200. The exhaust assembly 300 includes a mounting frame 310, an air guide plate 320, and a drive motor 330. The mounting frame 310 has an exhaust port 311 that communicates with the cooking cavity to exhaust hot air from the cooking cavity. The two ends of the air guide plate 320 are rotatably connected to the mounting frame 310 via a rotating shaft 321 to open or close the exhaust port 311 by rotation. The drive motor 330 is connected to the rotating shaft 321 to drive the rotating shaft 321 to rotate. The rotating shaft 321 is linked to the air guide plate 320, so that the air guide plate 320 can rotate under the drive of the drive motor 330. The air guide plate 320 can adjust the air outlet angle of the exhaust port 311 by rotating at different angles.

[0024] This invention, by configuring the exhaust assembly 300 into a structure that combines the mounting frame 310, the air guide plate 320, and the drive motor 330, allows the drive motor 330 to control the air guide plate 320 to rotate to the position of closing the exhaust port 311 during the early stages of cooking in the air fryer. This restricts all the hot air within the cooking chamber, causing the temperature inside the cooking chamber to rise rapidly so that the food cooks quickly. During the later stages of cooking, the drive motor 330 can control the air guide plate 320 to rotate to open the exhaust port 311, allowing some of the hot air inside the cooking chamber to be discharged through the exhaust port 311. The outward-flowing hot air can also carry away the water vapor and oil evaporated from the food inside the cooking chamber, causing a caramelized layer to form on the surface of the food, thereby improving the taste of the food. Because the rotation of the air guide plate 320 is controlled by the drive motor 330, during the cooking process, the drive motor 330 can control the air guide plate 320 to continuously swing, so as to continuously adjust the air outlet angle of the exhaust port 311. By sweeping the air up and down, uniform air outlet is achieved, avoiding the exhaust port 311 from continuously discharging hot air to the same position, which would cause furniture, walls, etc. directly facing the exhaust port 311 to be concentrated and damaged by heat, and reducing the heat accumulation near the exhaust port 311. Because when the opening of the exhaust port 311 increases, the airflow speed inside the cooking cavity can be accelerated. The rapid flow of hot air towards the exhaust port 311 will carry away a large amount of moisture and grease from the cooking cavity, thereby reducing the humidity inside the cooking cavity and slowing down the heating rate. When the opening of the exhaust port 311 decreases, less hot air is discharged from the cooking cavity, and a large amount of hot air, moisture, and grease accumulate inside the cooking cavity, which can increase the heating rate inside the cooking cavity and increase the humidity inside the cooking cavity. Therefore, the drive motor 330 drives the air guide plate 320 to rotate, making the opening size of the exhaust port 311 controllable. This allows for the adjustment of the humidity and heating rate inside the cooking cavity to suit the different dehydration and degreasing needs of different ingredients, thereby improving the cooked taste of the ingredients.

[0025] In this embodiment, there may be one or more air guide plates 320 (two or more). Preferably, there are multiple air guide plates 320 to improve the adjustment accuracy of the air guide plates 320 to the exhaust port 311, reduce the space occupied by the air guide plates 320 when rotating, and reduce the volume of the exhaust assembly 300. A connecting rod 340 is connected between any two adjacent air guide plates 320 so that all air guide plates 320 rotate together under the drive of the connecting rod 340. The drive motor 330 is connected to one of the multiple air guide plates 320. The setting of the connecting rod 340 realizes the synchronous rotation of the air guide plates 320, so that a single drive motor 330 can drive all air guide plates 320 to rotate synchronously.

[0026] The following explanation uses the example of two air guide plates 320.

[0027] like Figure 3As shown, a transmission shaft 322 is provided at the end of the air guide plate 320, which is arranged parallel to the rotating shaft 321. Since the rotating shaft 321 is the rotation center of the air guide plate 320, the transmission shaft 322 is eccentrically arranged. One end of the connecting rod 340 is rotatably connected to the transmission shaft 322 of one air guide plate 320, and the other end of the connecting rod 340 is rotatably connected to the transmission shaft 322 of the adjacent air guide plate 320. When one of the air guide plates 320 rotates, the transmission shaft 322 swings around the rotating shaft 321, and the connecting rod 340 drives the transmission shaft 322 on the adjacent air guide plate 320 to swing together, so that the two adjacent air guide plates 320 rotate at the same angle. The structure is simple and reliable.

[0028] like Figure 3 and Figure 9 As shown, the connecting rod 340 in this embodiment includes a rod body 341 and C-shaped retaining rings 342 located at both ends of the rod body 341. During installation, the C-shaped retaining rings 342 are engaged with the drive shaft 322 through their locking slots, thus achieving a rotatable connection between the connecting rod 340 and the drive shaft 322. This facilitates the installation and disassembly of the connecting rod 340, and allows for individual repair and replacement of the connecting rod 340 if it is damaged. Preferably, two annular positioning ribs 3221 are also provided on the drive shaft 322, located on both sides of the C-shaped retaining rings 342, to prevent the C-shaped retaining rings 342 from disengaging from the drive shaft 322 along its axial direction, ensuring stable transmission between the drive shaft 322 and the connecting rod 340. In order to improve the strength of the rod 341 and prevent the rod 341 from breaking, this embodiment provides a reinforcing rib 3411 protruding from the surface of the rod 341, and the reinforcing rib 3411 extends along the axial direction of the rod 341.

[0029] In this embodiment, the connecting rod 340 is located outside the mounting frame 310. An arc-shaped groove 312 is provided on the side of the mounting frame 310 away from the motor. The groove 312 is used to avoid the drive shaft 322, which passes through the groove 312 and exits the mounting frame 310 to connect with the connecting rod 340. By placing the connecting rod 340 outside the mounting frame 310, when the air guide plate 320 closes the exhaust port 311, the connecting rod 340 can be prevented from affecting the closing effect of the air guide plate 320 on the exhaust port 311, thus preventing air leakage between the side of the air guide plate 320 and the mounting frame 310. To further improve the closing effect when the air guide plate 320 closes the exhaust port 311, this embodiment preferably provides multiple sealing ribs 314 on the mounting frame 310. Sealing ribs 314 are provided on both the upper and lower sides of each air guide plate 320, such as... Figure 5 As shown, when the air guide plate 320 closes the exhaust port 311, the upper and lower sides of each air guide plate 320 abut against the sealing rib 314 to prevent air leakage from the upper and lower sides of the air guide plate 320.

[0030] In this embodiment, the connecting rod 340 and the drive motor 330 are located at the left and right ends of the air guide plate 320, respectively, to avoid interference between the connecting rod 340 and the drive motor 330. The mounting frame 310 is also provided with a shaft hole 313 for the shaft 321 to pass through. Figure 6 As shown, the pivot hole 313 for mounting the same guide plate is higher than the highest point of the slide groove 312 for mounting the same guide plate, so as to prevent the end of the air guide plate 320 with the connecting rod 340 from getting stuck in a self-locking position when rotating, and to ensure the smooth rotation of the air guide plate 320.

[0031] The mounting frame 310 includes a front frame 315 and a rear frame 316, which are detachably connected. Each frame has a semi-hole. When the front and rear frames are joined and locked, the semi-holes form a pivot hole 313 to accommodate the rotating shaft 321, thus positioning the air guide plate 320. The head unit 200 includes a housing and a top cover 210 housed within the housing. The rear frame 316 is integrally mounted on the top cover 210 to reduce assembly steps. The housing has mounting holes through which the front frame 315 passes, allowing communication with the outside. The structure is simple and easy to assemble. The sealing rib 314 can be located on either the front or rear frame 316, depending on the rotation requirements of the air guide plate 320. The rear frame 316 is provided with a mounting post 3161, and the drive motor 330 is locked to the mounting post 3161. The output shaft of the drive motor 330 is keyed to the end of the rotating shaft 321 to drive the motor. By setting the mounting post 3161 on the rear frame 316 which is integrally formed with the rear cover, the stability of the drive motor 330 can be improved.

[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
