Description

Technical Field

[0001] The utility model belongs to the technical field of air fryers, and particularly relates to an air fryer with frying and roasting functions. Background Art

[0002] The air fryer is a new type of household appliance that uses high-speed air circulation technology to cook food. The food it makes is like fried food, with a crispy surface. However, unlike traditional technology, it only requires little or no oil to make, which greatly reduces the risk of excessive oil intake for consumers. At the same time, cooking food in an air fryer also avoids the risk of burns from oil splashing and the disadvantage of inhaling large amounts of oil smoke during traditional frying. The cooking method is simple, safe and tastes excellent, so it is very popular among people.

[0003] However, most of the current air fryers have relatively simple functions and can only be used as a fryer. Although a few air fryers have frying and roasting functions, the cooking space is the same as the usage space of the fryer. When using, only one function can be selected, and frying and / or frying functions cannot be performed at the same time. This is inconvenient to use and also increases the cooking time. The user experience is greatly reduced, and the air fryer is likely to be idle. In addition, the heat dissipation effect of the current air fryer is not ideal, which can easily reduce the service life of the motor. Therefore, it is necessary to improve its structure.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] like Figure 1-4 As shown, the utility model is an air fryer with frying and grilling functions, including a shell 1, which is assembled from two inner and outer shells into a supporting frame body, and a heat dissipation cavity 2 and a first heating cavity 3 are sequentially arranged inside the shell. The heat dissipation cavities 2 are interconnected, and air can circulate inside. A driving component 21 is provided in the heat dissipation cavity 2, and a first heating element 31 is provided in the first heating cavity 3. The first heating element 31 generates heat through electrical connection, and the heat released can increase the air temperature in the fryer and achieve a frying effect. A heat dissipation hole 4 is provided on the rear wall of the shell 1, and corresponding exhaust ports are provided on the heat dissipation chamber 2 and the first heating chamber 3, which are respectively connected to the heat dissipation hole 4, and the opening area of ​​the exhaust port A of the heat dissipation chamber 2 is much larger than the opening area of ​​the exhaust port B of the first heating chamber 3, thereby preventing a large amount of heat flow from the first heating chamber 3 from entering the heat dissipation chamber 2; in addition, the setting of the heat dissipation hole 4 can discharge the gas in the heat dissipation chamber 2, thereby dissipating heat and cooling the driving component 21 in the heat dissipation chamber 2 to improve its service life; at the same time, the heat dissipation hole 4 has a pressure relief effect on the first heating chamber 3, thereby preventing the gas in the first heating chamber 3 from excessive expansion and damaging the product.

[0038] Specifically, such as Figure 5-6As shown, a heating component 5 is further provided on the shell 1. The interior of the heating component 5 is an overhead structure, which can further enhance the heat insulation effect. A baking tray 6 is provided on the top of the heating component 5. The baking tray 6 can be freely taken and placed, and the user can use it as a plate. It is easy to move and easy to clean. A second heating cavity 51 is formed between the baking tray 6 and the heating component 5. A second heating element 52 is provided in the second heating cavity 51. The first heating element 31 and the second heating element 52 can generate heat at the same time to improve cooking efficiency. They can also be used separately according to user needs without affecting each other. The shell 1 is also provided with a control panel 7, which is electrically connected to the first heating element 31 and the second heating element 52 respectively, and is used to control the first heating element 31 and / or the second heating element 52 to heat up at the same time, and the control panel 7 is provided with a plurality of touch-controllable buttons, such as a menu button, a start / pause button, a frying button, a temperature + / - button, etc., which are used to set the cooking method, temperature and time of different ingredients. Among them, when the air fryer mode and the frying mode are used at the same time, the mode can be adjusted by selecting the switching mode, and different modes can be controlled independently.

[0039] Furthermore, an insulation plate 53 is provided in the second heating chamber 51, and the insulation plate 53 is arranged between the second heating element 52 and the heating component 5. The electrically connected end of the second heating element 52 passes through the insulation plate 53 and is screwed to the insulation plate 53. Since a large amount of heat is generated when the frying and grilling mode is used, the setting of the insulation plate 53 can further insulate, greatly reducing the heat transfer downward during frying and grilling, thereby protecting the driving component 21 located in the heat dissipation chamber 2.

[0040] Furthermore, if Figure 7 As shown, supporting blocks 531 are provided at the four corners of the inner wall of the insulation plate 53, and the baking tray 6 is placed on the supporting blocks 531. The height of the supporting blocks 531 is H1, the height of the second heating chamber 51 is H2, the height of the second heating element 52 is H3, and H2>H1>H3. The height setting can prevent the baking tray 6 from directly contacting the second heating element 52 when it is placed on the supporting blocks 531, thereby reducing damage to the second heating element 52. At the same time, the peripheral wall of the insulation plate 53 can be used to limit the baking tray 6 to prevent the baking tray 6 from shifting or falling during the frying process.

[0041] Furthermore, if Figure 8-9As shown, the driving assembly 21 includes a motor 211 and a cooling fan 212. The output shaft 2111 of the motor 211 passes through the cooling fan 212 to drive the cooling fan 212 to rotate, accelerate the circulation of air and achieve a heat dissipation effect. The end of the output shaft 2111 passes through and extends into the first heating chamber 3. The convex setting on the top of the first heating chamber 3 can be regarded as the heat insulation cover 34 of the first heating chamber 3. An impeller 32 is provided in the heat insulation cover 34. The first heating element 31 is arranged around the impeller 32 and is screwed and fixed to the top of the inner wall of the heat insulation cover 34. The output shaft 2111 passes through the cooling fan 212 in sequence. and the impeller 32 to drive the cooling fan 212 and the impeller 32 to rotate synchronously. When the air fryer mode is started, the first heating element 31 will generate a large amount of heat. At the same time, the motor 211 starts to operate and drives the cooling fan 212 and the impeller 32 to rotate. The rotation of the impeller 32 can drive the heat emitted by the first heating element 31 to swirl, so that the swirling air circulates in the first heating chamber 3 and fully wraps the food to achieve an air frying effect. The heat generated during the air frying process will be transferred upward, and the rotation of the cooling fan 212 can dissipate the transferred heat in time and discharge the heat from the heat dissipation hole 4.

[0042] Furthermore, if Figure 10 As shown, a partition net 33 is further provided in the first heating chamber 3, and the output shaft 2111, the impeller 32 and the first heating element 31 are all arranged above the partition net 33. The setting of the partition net 33 can block the grease and water vapor splashed during air-frying food, avoiding grease pollution to the first heating element 31 and the impeller 32, affecting normal use. In addition, the partition net 33 is detachable, which is also convenient for later cleaning and safer to use.

[0043] Furthermore, if Figure 11-14As shown, the front and rear ends of the first heating chamber 3 are respectively provided with a front opening 8 and a rear opening 9. A drawer-type pot body 10 is also provided in the first heating chamber 3, and a heat-resistant handle 103 is provided on the peripheral wall of the pot body 10. When in use, the handle 103 of the pot body 10 is held and the pot body 10 is entered into the first heating chamber 3 along the front opening 8. To ensure that the pot body 10 is accurately placed in the first heating chamber 3, a downwardly extending limit block 11 is provided on the top of the first heating chamber 3 near the rear opening 9. The limit block 11 is fixedly connected or screwed to the shell 1, and a limit cavity 111 is provided on the limit block 11. The pot body 10 is provided with a convex block 101 adapted to the limit cavity 111. When the pot body 10 is placed in the first heating chamber 3, the convex block 101 is engaged with the limit cavity 111. To ensure the engagement When the cam 101 is in place, a limiting groove 112 is provided at the bottom of the limiting cavity 111, and a protrusion 102 corresponding to the limiting groove 112 is also provided at the bottom of the cam 101. When the cam 101 is snapped into place with the limiting cavity 111, the protrusion 102 and the limiting groove 112 are also snapped and fixed. At this time, the pot body 10 cannot be pulled out in the horizontal direction. The user needs to first lift the pot body 10 as a whole slightly upward to disengage the protrusion 102 from the limiting groove 112 before the pot body 10 can be pulled out from the first heating cavity 3 in the horizontal direction. This setting allows the user to quickly and accurately judge whether the pot body 10 is properly placed, and can also fix the pot body 10 so that it does not fall easily. Especially when carrying this air fryer, the pot body 10 will not automatically fall due to tilting, making transportation and movement safer and more reliable.

[0044] Furthermore, if Figure 14-15 As shown, the housing 1 further includes a base 13, which forms the bottom of the first heating chamber 3. The base 13 has an uneven texture where it contacts the bottom of the pot body 10, increasing friction with the pot body 10 and further stabilizing the pot body 10. Positioning blocks 131 are also provided around the edges of the base 13 where it contacts the pot body 10, further stabilizing the pot body 10. A sensor 12 is also provided within the base 13, working in conjunction with the pot body 10. The sensor 12 is signal-connected to the control panel 7. An opening 132 is provided in the base 13, through which the sensing end of the sensor 12 extends slightly. When the pot body 10 is placed within the first heating chamber 3, the sensing end of the sensor 12 automatically senses the air and contracts downward. When powered on, the sensor 12 also transmits a signal to the control panel 7, prompting the user to activate the air fryer with a sound or automatically illuminate the control panel 7, providing a better user experience.

[0045] The following is a detailed description of the working principle of the utility model:

[0046] When the user wants to use the air fryer function of the present invention, after the power is turned on, the screen of the control panel 7 will light up. The user only needs to select the fryer mode according to the button function operation of the control panel 7 to start. At this time, the first heating element 31 generates heat in the first heating chamber 3, and the impeller 32 rotates under the drive of the motor 211, and circulates the heat in the first heating chamber 3, so that the heat distribution is more uniform, the air frying effect of the food is better, and the taste is better; and the generated heat can be dissipated in time by the rotation of the cooling fan 212, and the heat is discharged from the cooling hole 4.

[0047] When the user wants to use the grilling function of the present invention, he only needs to select the grilling mode to start the grilling function. At this time, the second heating element 52 generates heat and transfers it to the grilling plate 6. The heat insulation plate 53 and the heating component 5 can isolate the heat generated by the second heating element 52, thereby preventing the motor 211 from being overheated and damaged. The user can also freely adjust the required heat level through the control panel 7 as needed.

[0048] The above two modes can also be operated simultaneously without affecting each other and can be controlled independently. You only need to select the corresponding mode on the control panel 7 to switch to this mode to realize the key operation. The operation is simple and clear, and the practicality is strong.

[0049] The innovation of the present invention lies in that a heating component and a second heating element are provided at the upper end of the present invention, which can enable the air fryer to perform air frying and frying functions at the same time, and can also use one of the functions separately. They do not interfere with each other and are independently controlled, meeting the user's needs for different functions and are not limited by the traditional single function; in addition, the heat dissipation cavity and the first heating cavity of the present invention are connected to the heat dissipation hole together, and the opening area of ​​the exhaust port A of the heat dissipation cavity is set to be larger than the opening area of ​​the exhaust port of the first heating cavity, so that the heat in the heat dissipation cavity can be quickly discharged to avoid damage to the motor due to overheating. The heat dissipation hole also has a pressure relief effect on the first heating cavity, preventing the gas in the first heating cavity from excessive expansion and damaging the product. The structural design is more reasonable and practical.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
