Description

An electric oven with an air fryer Technical Field

[0001] This utility model relates to the field of baking equipment technology, and in particular to an electric oven with an air fryer. Background Technology

[0002] Electric grills meet people's needs for grilling and frying food. They are simple to operate and are currently a popular small household appliance. For example, Chinese utility model patent CN221844514U discloses an easy-to-clean electric grill. This grill includes a main body with an open, upward-facing baking pan. The baking pan contains an electric heating element and a detachable wire rack mounted above the heating element. The heating element includes a contact point at one end of the baking pan and a curved heating tube connected to the contact point and extending towards the other end of the baking pan. The contact point is rotatably mounted on the grill body or baking pan via a pivot assembly. When cleaning is required, the wire rack is removed from above the heating element. The heating element is then grasped and swung upwards. The contact point of the heating element rotates relative to the grill body or baking pan around the pivot assembly, creating sufficient operating space between the lower surface of the heating element and the baking pan for thorough cleaning. This avoids problems such as reduced heating efficiency and food safety issues caused by oil residue, thus improving heating efficiency and extending the lifespan of the heating element. However, this electric oven has a single function; it can only fry or grill food and cannot meet the diverse cooking needs of consumers.

[0003] Therefore, existing technologies still need to be improved and developed to address the aforementioned issues. Technical solutions

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an electric oven with an air frying function.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides an electric grill with an air fryer, including a base and a top cover. The top cover is disposed on the base, specifically, the top cover is detachably disposed on the upper end of the base. A grilling rack, a first heating element, and an oil collection tray are arranged sequentially from top to bottom on the base. Specifically, the first heating element is a heating tube structure. The grilling rack, the first heating element, and the oil collection tray are all detachably installed on the base, facilitating disassembly and cleaning of the grilling rack, the first heating element, and the oil collection tray. A cavity is formed between the top cover and the oil collection tray. The first heating element divides the cavity into a first cavity and a second cavity that are connected vertically. A hot air channel is provided on the base, and a fluid drive mechanism is provided within the hot air channel. The air inlet of the hot air channel is connected to the second cavity, and the air outlet of the hot air channel is connected to the first cavity. With the above structural design, a hot air channel and a fluid drive mechanism are added to the base of the electric oven, so that the cavity between the top cover and the oil tray forms a sealed hot air circulation channel with the hot air channel. When the grilling function is needed, simply open the top cover and control the first heating element to work, and the food above the first heating element can be grilled. When the air frying function is needed, close the top cover and control the first heating element and the fluid drive mechanism to work. The fluid drive mechanism guides the hot air below the first heating element, i.e., in the second cavity, into the hot air channel, and then flows out from the hot air channel to air fry the food above the first heating element, meeting the needs of consumers for multiple cooking methods.

[0007] According to the above scheme, a second heating element is provided in the hot air channel, specifically a heating tube structure. The second heating element conducts heat through contact with the gas in the hot air channel. This structural arrangement further heats the air in the hot air channel, enhancing the air frying effect. Furthermore, it is possible to configure the system to heat the food by only activating the second heating element and the fluid drive mechanism.

[0008] This utility model also includes an air inlet cover, which is located above the air inlet and has an air inlet hole. The air inlet is located on the oil receiving tray. This structural design facilitates the entry of hot air below the first heating element (i.e., hot air from the second cavity) into the hot air channel under the drive of the fluid-driven mechanism. Simultaneously, it can block oil from entering the hot air channel by blocking the outside of the air inlet cover. The air inlet cover is detachable from the air inlet for easy removal and cleaning.

[0009] According to the above scheme, the fluid drive mechanism includes a drive motor, centrifugal fan blades, and a motor bracket. The motor bracket is fixed to the base, and the drive motor is fixedly mounted on the motor bracket. The centrifugal fan blades are located inside the hot air channel. The output shaft of the drive motor is drively connected to the centrifugal fan blades. A mounting cavity is formed inside the base, and both the motor bracket and the drive motor are located within the mounting cavity. Specifically, one or more fluid drive mechanisms can be installed according to the product's airflow requirements. The centrifugal fan blades are fixed to the output shaft of the drive motor. This structural arrangement facilitates the circulation of hot air between the cavity and the hot air channel.

[0010] According to the above scheme, the fluid drive mechanism further includes cooling fan blades, which are fixed on the output shaft and correspondingly arranged with the drive motor. The cooling fan blades blow air towards the drive motor. With the above structural arrangement, the cooling fan blades rotate synchronously while the centrifugal fan blades rotate, and the cooling fan blades blow cool air towards the drive motor, which is beneficial to the heat dissipation of the drive motor.

[0011] According to the above scheme, the air outlet of the hot air channel is positioned higher than the first heating element and the grill rack, and the air outlet is correspondingly positioned to the grill rack. Specifically, the hot air flowing out of the air outlet 122 of the hot air channel 12 blows downwards onto the grill rack 3. Through the above structural arrangement, the hot air flowing out of the air outlet 122 can naturally come into contact with the food on the grill rack 3, greatly improving the food heating efficiency.

[0012] This invention also includes a smoking mechanism, comprising a smoking box containing smoking materials. The smoking box is located within and in fluid communication with the hot air channel. This structural arrangement allows the smoke generated within the smoking box to flow through the hot air channel to the top of the grill and contact the food, thus enhancing the smoking function of this invention.

[0013] According to the above scheme, the smoking box is in contact with the second heating element for heat conduction, and the smoking material is ignited by the heat. Specifically, the smoking material used here is smoking granules. With the above structural arrangement, the smoking material placed in the smoking box can be ignited by the heat of the second heating element to produce smoke.

[0014] According to the above scheme, the smoking mechanism includes a third heating element, which is disposed within the hot air channel. The third heating element contacts and conducts heat with the smoking box, and the smoking material is ignited by the heat. With the above structural arrangement, the smoking material in the smoking box can be ignited by individually controlling the heating of the third heating element.

[0015] According to the above scheme, a coupler is fixedly installed inside the base, and the wiring terminal of the first heating element is detachably inserted into the coupler. Specifically, the coupler is fixed inside the base, and during assembly, the pin of the first heating tube is directly inserted into the coupler. This structural design facilitates the disassembly and cleaning of the first heating element after use. Beneficial effects

[0016] The beneficial effects of this utility model are:

[0017] This invention adds a hot air channel and a fluid drive mechanism to the base of the electric oven, so that the cavity between the top cover and the oil tray forms a sealed hot air circulation channel with the hot air channel. When the grilling function is needed, simply open the top cover and control the first heating element to work, and the food above the first heating element can be grilled. When the air frying function is needed, close the top cover and control the first heating element and the fluid drive mechanism to work. The fluid drive mechanism guides the hot air below the first heating element into the hot air channel, and then flows out from the hot air channel to air fry the food above the first heating element, thus meeting the needs of consumers for multiple cooking methods.

[0024] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments. Example

[0025] As shown in Figures 1-5, the arrows in the figures indicate the direction of hot air flow. This utility model provides an electric oven with an air fryer, including a base 1 and an upper cover 2. The upper cover 2 is placed on the base 1. Specifically, the upper cover 2 is detachably placed on the base 1. The upper cover 2 is equipped with a micro switch, which is used to control the air fryer. When the upper cover 2 leaves the base 1 or when the upper cover 2 is not tightly closed to the base 1, the micro switch is turned off, and the air fryer function is not activated. The base 1 is provided with a grill rack 3, a first heating element 4, and an oil collection tray 5 arranged sequentially from top to bottom. Specifically, the first heating element 4 is a heating tube structure. The grill rack 3, the first heating element 4, and the oil collection tray 5 are all detachably installed on the base 1, which facilitates the disassembly and cleaning of the grill rack 3, the first heating element 4, and the oil collection tray 5. A cavity is formed between the upper cover 2 and the oil collection tray 5. The first heating element 4 divides the cavity into a first cavity 21 and a second cavity 11 that are connected vertically. A hot air channel 12 is formed on the base 1. A fluid drive mechanism 6 is provided in the hot air channel 12. The air inlet 121 of the hot air channel 12 is connected to the second cavity 11, and the air outlet 122 of the hot air channel 12 is connected to the first cavity 21. With the above structural design, a hot air channel 12 and a fluid drive mechanism 6 are added to the base 1 of the electric oven, so that the cavity between the upper cover 2 and the oil receiving tray 5 forms a sealed hot air circulation channel with the hot air channel 12. When the grilling function is needed, simply open the upper cover 2 and control the first heating element 4 to work, thus achieving grilling of the food above the first heating element 4. When the air frying function is needed, close the upper cover 2 and control the first heating element 4 and the fluid drive mechanism 6 to work. The fluid drive mechanism guides the hot air below the first heating element 4, i.e., in the second cavity 11, into the hot air channel 12, and then flows out from the hot air channel 12 to air fry the food above the first heating element 4, meeting the needs of consumers for various cooking methods. The grill rack 3 described in this embodiment is a baking pan with a hollow bottom structure.

[0026] Furthermore, a second heating element 7 is provided inside the hot air channel 12. The second heating element 7 conducts heat with the gas inside the hot air channel 12 through contact. Specifically, the second heating element 7 is a heating tube structure. Through the above structural arrangement, the air inside the hot air channel 12 can be further heated, enhancing the working effect of the air fryer function.

[0027] This utility model also includes an air inlet cover 8, which has an air inlet hole 81. Specifically, the air inlet hole 81 can be located on the side or top of the air inlet cover 8, or other locations that are not conducive to oil flow. The air inlet 121 of the hot air channel 12 is opened on the oil receiving tray 5, and the air inlet cover 8 is located above the air inlet 121. With the above structural arrangement, it is beneficial for the hot air below the first heating element 4 (i.e., the hot air in the second cavity 11) to enter the hot air channel 12 under the drive of the fluid driving mechanism 6. At the same time, it can block the cooking oil on the outside of the air inlet cover 8 to prevent cooking oil from entering the hot air channel 12. The air inlet cover 8 is detachably mounted on the air inlet 121 for easy removal and cleaning.

[0028] Furthermore, the fluid drive mechanism 6 includes a drive motor 61, a centrifugal fan blade 62, and a motor bracket 63. The motor bracket 63 is fixed inside the base 1, and the drive motor 61 is fixedly mounted on the motor bracket 63. The centrifugal fan blade 62 is disposed inside the hot air channel 12, and the output shaft of the drive motor 61 is drively connected to the centrifugal fan blade 62. A mounting cavity 13 is formed inside the base 1, and both the motor bracket 63 and the drive motor 61 are disposed within the mounting cavity 13. Specifically, one or more fluid drive mechanisms 6 can be installed according to the product's airflow requirements, and the centrifugal fan blade 62 is fixed on the output shaft of the drive motor 61. This structural arrangement facilitates the circulation of hot air between the cavity and the hot air channel 12.

[0029] Furthermore, the fluid drive mechanism 6 also includes a cooling fan blade 64, which is fixed to the output shaft and blows air onto the drive motor 61. With this structural arrangement, the cooling fan blade 64 rotates synchronously with the centrifugal fan blade 62, blowing cool air onto the drive motor 61, which is beneficial for heat dissipation of the drive motor 61.

[0030] Furthermore, the air outlet 122 of the hot air channel 12 is higher than the first heating element 4 and the grill rack 3, and the air outlet 122 is positioned opposite to the grill rack 3. Specifically, the hot air flowing out of the air outlet 122 of the hot air channel 12 blows downwards onto the grill rack 3. Through the above structural arrangement, the hot air flowing out of the air outlet 122 can come into contact with the food on the grill rack 3, greatly improving the food heating efficiency.

[0031] This invention also includes a smoking mechanism, which comprises a smoking box 9 containing smoking materials. The smoking box 9 is located within and in fluid communication with the hot air channel 12. This structural arrangement allows the smoke generated within the smoking box 9 to flow through the hot air channel 12 to the top of the grill 3 and contact the food, thus enhancing the smoking function of this invention.

[0032] Furthermore, the smoking mechanism includes a third heating element 10, which is disposed within the hot air channel 12. The third heating element 10 contacts and conducts heat with the smoking box 9, igniting the smoking material. With this structural arrangement, the smoking material within the smoking box 9 can be ignited by individually controlling the heating of the third heating element 10.

[0033] Furthermore, the first heating element 4 is a first heating tube, and a coupler 14 is fixedly installed inside the base 1. The wiring terminal of the first heating tube is detachably inserted into the coupler 14. Specifically, the coupler 14 is fixed inside the base 1, and during assembly, the lead-in part of the first heating tube is directly inserted into the coupler 14. Through the above structural design, the first heating element 4 can be easily disassembled and cleaned after use. Example

[0034] [Correction 24.10.2025 based on Rule 91] As shown in Figure 5, this utility model provides an electric grill with an air fryer, which is basically the same in structure as Embodiment 1, except that: the grill rack 3 is a grilling net, which is placed above the first heating element by a support frame. With the above structural design, more ingredients can be cooked using the air fryer function, resulting in more even heating of the ingredients.

[0035] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
