[0003] To achieve functions such as hot air circulation, heat dissipation, and steam extraction, existing air fryers typically require independent configurations of a circulation fan, a cooling fan, and an extraction fan. Each fan often uses a separate motor drive structure, resulting in the need for multiple sets of drive mechanisms and transmission components inside.
[0004] Therefore, it is necessary to propose a new technical solution to overcome the shortcomings of existing technologies. Utility Model Content

When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.
[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0052] like Figures 1 to 6 As shown, this application provides a cooking appliance 100, including a body 10, a heating device 20, a heat dissipation device 30, and a suction device 40. The body 10 defines a cooking cavity 11 inside. The heating device 20 includes a heating element 21 and a circulating fan 22, which is configured to drive the gas heated by the heating element 21 to flow into the cooking cavity 11. The heat dissipation device 30 includes a heat dissipation fan 31, which is configured to dissipate heat from the cooking appliance 100. The suction device 40 includes a suction channel 41 and a suction fan 42, which drives the gas in the cooking cavity 11 to be discharged through the suction channel 41. The cooking appliance 100 also includes an output component 50, which includes an output shaft 51, which is configured to be driven to rotate about a fixed axis. The circulating fan 22, the heat dissipation fan 31, and the suction fan 42 are all fixedly connected to the output shaft 51 so that the output shaft 51 synchronously drives the circulating fan 22, the heat dissipation fan 31, and the suction fan 42 to rotate.
[0053] When the cooking appliance 100 is in use, the output shaft 51 of the output component 50 rotates around a fixed axis, and the circulating fan 22, the cooling fan 31 and the suction fan 42 fixed to the output shaft 51 rotate synchronously. The circulating fan 22 generates airflow under the drive of the rotating shaft, and the airflow forces the hot air generated by the heating element 21 into the cooking cavity 11. The cooling fan 31, driven by the output shaft 51, exhausts the heat generated by the heating element in the cooking appliance 100. The suction fan 42, driven by the output shaft 51, exhausts the gas in the cooking cavity 11 through the suction channel 41.
[0054] The output component 50 can synchronously drive the circulating fan 22, the cooling fan 31, and the suction fan 42, which significantly simplifies the transmission system and eliminates the complexity of multi-motor coordinated control. In addition, it can also reduce the space inside the cooking appliance 100, making the structure of the cooking appliance 100 more compact.
[0055] In this embodiment, as Figures 1 to 6 As shown, the cooking appliance 100 can be an air fryer. The main body includes a pot body 12 and a lid 13. The lid 13 is disposed on the pot body 12, and the heating device 20, the heat dissipation device 30, and the suction device 40 are all disposed on the lid 13. The interior of the pot body 12 defines a cooking cavity 11 with an open top. The lid 13 is pivotally connected to the pot body 12 and can be fastened to the top of the pot body 12 to close the top opening of the cooking cavity 11.
[0056] In this embodiment, as Figures 2 to 6 As shown, along the axial direction of the output shaft 51, the suction fan 42 is located between the circulation fan 22 and the cooling fan 31, and the circulation fan 22 is closer to the cooking cavity 11, so that the layout of the cooking appliance 100 is more reasonable, thereby making the structure of the cooking appliance 100 more compact.
[0057] In this embodiment, as Figures 2 to 6 As shown, the circulating fan 22 includes a circulating shaft and multiple circulating blades. The multiple circulating blades are spaced apart around the outer circumference of the circulating shaft. The circulating shaft is sleeved on the outside of the output shaft 51 and fixedly connected to the output shaft 51. The heating element 21 is generally ring-shaped. The heating element 21 can adopt existing technology, which will not be further described here. For example, the heating element 21 is a far-infrared heating tube, a halogen tube, a light wave heating tube, or an electric heating tube, etc.
[0058] In this embodiment, as Figures 2 to 6As shown, the circulating fan 22 and the heating element 21 are both located on one side of the cooking chamber 11, and the heating element 21 is closer to the cooking chamber 11 than the circulating fan 22, so that the airflow generated by the circulating fan 22 carries the air heated by the heating element 21 into the cooking chamber 11. The cover 13 has a first cavity 131, which is connected to the cooking chamber 11, and the heating element 21 and the circulating fan 22 are disposed in the first cavity 131.
[0059] Specifically, the cooking appliance 100 also includes a cover 14, which is fixed to the side of the cover 13 facing the cooking cavity 11 by screws or welding, so that the cover 14 and the cover 13 form a first cavity 131. The cover 14 has multiple through holes that connect the first cavity 131 to the cooking cavity 11. The heating element 21 is fixed inside the cover 14 by a structure such as a snap-fit.
[0060] In this embodiment, as Figures 2 to 6 As shown, the airflow generated by the cooling fan 31 can remove excess heat from the cover 13; specifically, the airflow generated by the cooling fan 31 can remove the heat transferred to the second cavity 132 by components such as the control module and heating element 21, and expel the heat outside the cooking appliance 100. The cooling fan 31 includes a cooling shaft and multiple cooling blades, which are spaced apart around the outer periphery of the cooling shaft. The cooling shaft is sleeved on the outside of the output shaft 51 and fixed to the output shaft 51.
[0061] In this embodiment, as Figures 2 to 6 As shown, the cover 13 has a second cavity 132, which communicates with the outside. The cooling fan 31 is disposed in the second cavity 132. The top of the cover 13 has an air outlet that communicates with the second cavity 132, so that the airflow generated by the cooling fan 31 can flow out through the air outlet.
[0062] In this embodiment, as Figures 2 to 6 As shown, when cooking food in an air fryer, the oil fumes produced cannot be expelled from the relatively enclosed pot. After a period of use, an oil film forms inside the pot, which is difficult to clean. The problem can be solved by using a suction fan 42 driven by an output shaft 51 to generate suction force, which causes the gas in the cooking chamber 11 to be discharged directionally through the suction channel 41.
[0063] In this embodiment, as Figures 2 to 6 As shown, the suction fan 42 is a centrifugal fan; the suction fan 42 includes a suction shaft and multiple suction blades, the multiple suction blades being spaced apart around the outer circumference of the suction shaft, the suction shaft being sleeved on the outside of the output shaft 51 and fixedly connected to the output shaft 51. The cover 13 has a third cavity 133, the third cavity 133 being connected to the suction channel 41, and the suction fan 42 being disposed within the third cavity 133.
[0064] In this embodiment, as Figures 2 to 6 As shown, the suction channel 41 is connected to the cooking cavity 11 through multiple suction ports 411; the multiple suction ports 411 are arranged on the top of the cooking cavity 11 and around the circumference of the cooking cavity 11; the multiple suction ports 411, together with the negative pressure airflow generated by the suction fan 42, can capture the rising oil fumes in the cooking cavity 11 in all directions, avoid the oil fumes from condensing on the cavity wall to form an oil film that is difficult to clean, and significantly reduce the difficulty of cleaning the inner cavity after cooking.
[0065] Preferably, the suction ports 411 are distributed on the left, right, and rear sides of the cooking cavity 11. The cooking utensil 100 has a front, a rear, and left and right sides; the front of the cooking utensil 100 refers to the side directly facing the operator when the cooking utensil 100 is in normal use (e.g., the side where the user stands to pick up or place ingredients and adjust parameters); the rear of the cooking utensil 100 is the side opposite the front, facing the background of the operating environment (e.g., a kitchen wall); the left and right sides refer to the two sides of the utensil corresponding to the left and right hands of the operator when facing the front of the cooking utensil 100. The left, right, and rear sides of the cooking cavity 11 correspond to the left, right, and rear sides of the cooking utensil 100.
[0066] In this embodiment, as Figures 2 to 6 As shown, the suction device 40 also includes a filter element 43, which is disposed at the outlet of the suction channel 41. The filter element 43 purifies the exhaust gas, significantly reducing exhaust pollution. The filter element 43 can be connected to the suction channel 41 using a modular snap-fit structure, facilitating disassembly and cleaning by the user.
[0067] In this embodiment, as Figures 2 to 6 As shown, the output component 50 is a motor. The specific structure of the motor can refer to the prior art; for example, the motor includes a housing, a stator assembly, a rotor assembly, and an output shaft 51; the stator assembly and the rotor assembly are both located inside the housing; the output shaft 51 is fixedly connected to the rotor assembly. The output shaft 51 passes through the entire housing and forms a first output section 511 and a second output section 512 on both sides of the housing; the cooling fan 31 is fixedly connected to the first output section 511; the circulating fan 22 and the suction fan 42 are both fixedly connected to the second output section 512; the first output section 511 and the second output section 512 are respectively located on both sides of the output component 50.
[0068] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.
[0069] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
