DETAILED DESCRIPTION

[0032] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the accompanying drawings in the embodiments of the present application.

[0033] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0034] 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 the present application belongs. The terms used in the specification of the present application herein are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0035] Referring to Figures 1-7 The present application discloses an easy heat dissipation cooking utensil, which comprises a cooking body 10 and a heat insulation assembly. The cooking body 10 is provided with a cooking cavity 14 and a heating element. The top end of the cooking body 10 is provided with a first air inlet 12 and an air outlet 11, and the bottom end of the cooking body 10 is provided with a second air inlet 13.

[0036] The specific heat insulation assembly includes a first heat insulation cover 30 and a second heat insulation cover 40. The first heat insulation cover 30 is arranged at the top end of the cooking cavity 14, and the second heat insulation cover 40 is arranged at the top end of the first heat insulation cover 30. Thus, after the first heat insulation cover 30 and the second heat insulation cover 40 are assembled to the cooking body 10, a first air flow space is formed between the inner wall of the second heat insulation cover 40 and the outer wall of the first heat insulation cover 30. A second air flow space is formed between the outer wall of the first heat insulation cover 30 and the inner wall of the cooking body 10. It should be noted that the inner wall of the cooking body 10 refers to the part outside the cooking cavity 14, that is, the second air flow space is formed between the second heat insulation cover 40 and the inner wall of the cooking body 10, which is the space in the cooking body 10 outside the cooking cavity 14.

[0037] In addition, the first heat insulation cover 30 is provided with a first through hole 312 and a drainage channel 311. One end of the drainage channel 311 penetrates to the cooking cavity 14, and the other end of the drainage channel 311 communicates with the first through hole 312. The second heat insulation cover 40 is provided with a second through hole 411, which is arranged corresponding to the first through hole 312. One side of the first air flow space communicates with the first air inlet 12, and the other side of the first air flow space communicates with the air outlet 11. The first air flow space is provided with a first drainage fan 90. The second air flow space communicates with the second air inlet 13, and the second air flow space is provided with a second drainage fan 70. The air outlet end of the second drainage fan 70 penetrates through the second through hole 411 and communicates with the first through hole 312.

[0038] Based on the above structure, when the cooking action is performed, the food is placed in the cooking utensil 20, and then the cooking utensil 20 is placed in the cooking cavity 14. The heating element can be installed at the bottom end of the first heat insulation cover 30. Thus, the heating element can heat the cooking cavity 14 below the first heat insulation cover 30, so that the food in the cooking utensil 20 can be cooked.

[0039] Specifically, when the cooking cavity 14 is heated and cooked, the second drainage fan 70 can be started. The second drainage fan 70 can rotate to drive the gas in the second air flow space formed by the second heat insulation cover 40 and the inner wall of the cooking body 10 to flow. The external gas can enter the second air flow space through the second air inlet 13 at the bottom end of the cooking body 10, and then enter the air inlet end of the second drainage fan 70 under the action of the second drainage fan 70, enter the drainage channel 311 through the air outlet end of the second drainage fan 70, and be guided to the cooking cavity 14 through the drainage channel 311. The heat in the cooking cavity 14 flows, so that the hot air flows to cook the food in the cooking cavity 14, and the heating effect of the hot air flowing to the food is more uniform.

[0040] Meanwhile, since the heating element is arranged below the first heat shield 30, the first heat shield 30 can block the heat in the cooking cavity 14 in the cooking cavity 14, reducing the loss of heat. While the second heat shield 40 is capped above the first heat shield 30, the first air flow fan 90 in the first air flow space 50 between the second heat shield 40 and the first heat shield 30 can be rotated, and the external air flow can enter one side of the first air flow space 50 through the first air inlet 12 and be guided out of the air outlet 11 on the other side of the first air flow space 50 under the action of the first air flow fan 90. In this way, the first air flow fan 90 can guide the external air flow to the first air flow space 50 and guide the heat in the first air flow space 50 out through the air outlet 11, so that the heat generated during cooking in the cooking cavity 14 can be directly taken away under the action of the first air flow fan 90, and the heat will not flow upward and be directly guided out of the lower first air flow space 50 by the first air flow fan 90, avoiding the concentration of heat at the top of the cooking machine body 10, so that the top heat of the cooking machine body 10 is low during cooking.

[0041] Of course, the air flow in the second air flow space formed between the first heat shield 30 and the inner wall of the cooking machine body 10 also flows under the action of the second air flow fan 70, that is, even if the heat in the first air flow space 50 is transmitted to the top of the second heat shield 40, the second air flow fan 70 can guide it to re-enter the cooking cavity 14, which effectively reduces the top heat of the cooking machine body 10 and effectively reduces the overheating of the top of the cooking machine body 10 during cooking.

[0042] In addition, it should be noted that the first air flow fan 90 is arranged between the first heat shield 30 and the second heat shield 40, and the second air flow fan 70 for guiding the air flow into the cooking cavity 14 is arranged on the first heat shield 30, and the two are arranged staggered in the circumferential direction of the cooking machine body 10, which can effectively reduce the height of the machine body 10.

[0043] Further, a flow guide member can be arranged in the flow guide channel 311, which can guide the air flow in the flow guide channel 311 to enter the cooking cavity 14 in a rotational flow manner. In this way, after being guided into the flow guide channel 311 by the second air flow fan 70, the flow guide member can guide the entering air flow to enter in a rotational flow manner. In this way, the rotational flow can make the heat and gas fully mixed and flow, and the heating effect is more uniform.

[0044] The drainage member in the embodiment includes a drainage seat 81 and drainage blades 82, which are connected to the outer peripheral wall of the drainage seat in a spiral manner; the drainage seat 81 is fixed with the drainage channel 311, and a bolt can be arranged on the drainage seat 81, which sequentially penetrates through the second heat shield 40, the first heat shield 30, and is connected and assembled with the drainage seat 81; and the gas entering the drainage channel 311 can flow along the spiral drainage blades 82, so that the gas flows in a spiral manner, which can make the gas flow in a spiral manner without additionally arranging a rotating fan, so that the gas can flow in a spiral manner, fully mixed with heat, and has a good heating and cooking effect.

[0045] It should be noted that, since the drainage blades are arranged in a spiral manner to achieve drainage in the embodiment, when the gas flows in, the gas can directly flow along the extension direction of the drainage blades, without the need to additionally arrange a motor to drive the blades to rotate to achieve drainage, but only need to arrange a fan to guide the air flow, which can drive the gas to flow in a spiral manner during the air flow process, enter the cooking cavity, fully mix with heat, and then flow from top to bottom, so that the food materials in the cooking cavity are fried by hot air, which can also reduce the arrangement of the motor, reduce the cost, and also can reduce the internal space of the cooking machine body without simultaneously arranging the motor and the blades.

[0046] Of course, a spiral groove can also be directly machined on the inner wall of the drainage channel 311, or a threaded blade can also be directly arranged on the inner wall of the drainage channel 311, which can also make the gas entering the drainage channel 311 flow in a spiral manner.

[0047] Further, in order to facilitate the machining of the drainage channel 311, the top middle part of the first heat shield 30 can be upwardly protruded and formed into a first protruding part 31, and the above-mentioned drainage channel 311 is arranged in the first protruding part 31, and the first through hole 312 is arranged on the side part of the first protruding part 31, so that the drainage channel 311 is formed in the first protruding part 31 protruding from the middle part of the first heat shield 30, which can form a relatively sealed drainage channel 311, and facilitate the assembly of the drainage member.

[0048] More specifically, the part of the first heat shield 30 surrounding the first protruding part 31 is formed into a first mounting area 32, the first drainage fan 90 is mounted in the first air flow space and mounted in the first mounting area 32, so that the first drainage fan 90 is not higher than the top end surface of the first protruding part 31, and thus, after the assembly of the first drainage fan 90, the first drainage fan 90 will not protrude from the first heat shield 30, and the overall assembly height will not be increased due to the additionally arranged first drainage fan 90, which effectively reduces the internal assembly height and reduces the overall height of the cooking machine body 10.

[0049] In order to match the structure of the first heat shield 30, a further protrusion is formed in the middle of the top end of the second heat shield 40 as a second protrusion 41, which is hollow and sleeved outside the first protrusion 31, and the second through hole 411 is arranged on the side of the second protrusion 41 and corresponds to the first through hole 312, that is, after the second heat shield 40 is sleeved on the first heat shield 30, the hollow structure of the second protrusion can be sleeved on the first protrusion 31 of the first heat shield 30, which can achieve the effect of positioning assembly, and can also reduce the assembly height after the two are assembled.

[0050] Similarly, the part of the second heat shield 40 surrounding the second protrusion 41 is formed as a second mounting area 43, the end face of the second mounting area 43 is lower than the top end face of the second protrusion 41, and the second air guide fan 70 is mounted on the second mounting area 43 and is not higher than the top end face of the second protrusion 41. In this way, after the second air guide fan 70 is assembled, it will not protrude from the second heat shield 40, and the overall assembly height will not be increased due to the additional second air guide fan 70, effectively reducing the internal assembly height and the overall height of the cooking machine body 10.

[0051] Further, an air guide channel can also be arranged on the second heat shield 40, one end of the air guide channel is in communication with the first air flow space, and the other end of the air guide channel is in communication with the first air inlet 12. When the first air guide fan 90 is in operation, the first air inlet 12 can guide the external air flow into the air guide channel and into the first air flow space between the first heat shield 30 and the second heat shield 40, achieving effective heat dissipation.

[0052] Further, the air inlet end of the second air guide fan 70 is arranged upwardly, so that the air flow entering the second air inlet 13 at the bottom end of the cooking machine body 10 can flow upwardly to the top air inlet end of the second air guide fan 70, so that the air flow path is long and the flow rate is stable.

[0053] Further, the cooking cavity 14 is detachably provided with a cooking utensil 20. Specifically, taking an air fryer as an example of an easy heat dissipation cooking utensil, the cooking machine body 10 is an air fryer body 10, and the cooking utensil 20 is a basket structure. When the easy heat dissipation cooking utensil is a steamer, the cooking utensil 20 can be a steaming grid. When the easy heat dissipation cooking utensil is an oven, the cooking utensil 20 can be a baking tray structure in a drawer.

[0054] The technical means disclosed in the present application scheme is not limited to the technical means disclosed in the above embodiments, but also includes technical solutions composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which are also considered within the scope of protection of the present application.
