With technological advancements, current oven cooking modes have evolved from traditional baking to hot air baking and air frying. For successful hot air baking or air frying, heat exchange rate is paramount. Factors influencing heat exchange efficiency include hot air velocity and temperature. Current hot air methods place fan blades alongside the heating tube to quickly dissipate heat. However, this is only effective during the heating phase; a constant temperature is often desired during cooking. Furthermore, the heating tube operates intermittently, and the proximity of the tube to the fan blades results in a high temperature rise in the fan motor. This necessitates additional insulation and heat dissipation treatment of the hot air assembly, increasing the complexity and size of the entire system.

[0003] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art. Utility Model Content

[0030] like Figure 1 、 Figure 2 As shown, an embodiment of the present invention provides a hot air assembly, comprising a hot air chamber 12, a fan 3 disposed within the hot air chamber 12, an opening disposed on the side of the hot air chamber 12, a baffle 4 disposed within the opening, an air outlet 41 disposed at the top of the baffle 4, and a plurality of mesh-shaped air inlet holes 42 disposed in the middle of the baffle 4. In this embodiment, the area of the air inlet holes 42 covering the baffle 4 is circular. The air outlet side of the fan 3 faces the air outlet 41, facilitating air flow from the hot air chamber 12 through the air outlet 41 into the heating chamber 11 within the heating liner 1 of the cooking device.

[0031] refer to Figure 1 、 Figure 2As shown, when the hot air assembly provided by the embodiment of the present invention is installed and operated, the hot air chamber 12 is arranged on the side wall of the heating inner pot 1 of the cooking device, for example, the left side wall, and the baffle 4 is arranged between the hot air chamber 12 and the heating cavity 11 of the heating inner pot 1 of the cooking device. When the hot air function is activated, the heating element 2 at the top of the heating cavity 11 and the fan 3 in the left hot air chamber 12 work together. When the fan 3 is working, the rotation of the fan blades accelerates the air in the hot air chamber 12, and eventually enters the heating cavity 11 through the air outlet 41 at the top of the baffle 4. After being heated by the heating element 2 at the top of the heating cavity 11, the air is turned into high-speed hot air. The high-speed hot air hits the right wall of the heating cavity 11 and flows to the left. The middle area of the baffle 4 is provided with multiple air inlet holes 42 in the shape of a mesh, and the returning hot air enters the left hot air chamber 12 again for acceleration, thus forming a cycle that continues to circulate. The hot air assembly provided in the embodiment of the present invention has a hot air chamber 12 with no heating element and only a fan 3 arranged on the side of the heating chamber 11 of the cooking device, and a heating element 2 is arranged on the top of the heating chamber 11. When the cooking device starts the hot air mode, the heating element 2 on the top of the heating chamber 11 and the fan 3 on the side work together to form a hot air circulation, thereby improving the heating efficiency and use effect of the cooking device. In addition, the hot air assembly provided in the embodiment of the present invention separates the motor and blades of the fan 3 from the heating element 2, reducing the temperature rise of the motor and blades, and increasing the service life of the motor and blades, that is, increasing the service life of the fan 3. At the same time, since the heating element 2 is arranged separately from the motor and blades of the fan 3, the heat insulation and heat dissipation measures of the cooking device can be reduced, the thickness and complexity of the system can be reduced, the volume ratio of the whole machine can be improved, the space utilization rate can be improved, and the space occupancy can be reduced.

[0032] like Figure 1 、 Figure 2 As shown, in a preferred embodiment of the present invention, the fan 3 includes a motor 31 and blades 32. The blades 32 are located inside the hot air chamber 12, and the motor 31 is located outside the hot air chamber 12. In this embodiment, the motor 31 is further away from the heating element 2, and due to the obstruction of the outer wall of the hot air chamber 12, the temperature rise of the motor 31 of the fan 3 is greatly reduced, thereby extending the service life of the motor 31.

[0033] like Figure 2 、 Figure 3 、 Figure 4 As shown, in one embodiment of the present invention, the fan 3 is an axial flow fan, the motor shaft of which is perpendicular to the rotation plane of the fan blades, and the motor 31 of the axial flow fan is mounted on the left side of the hot air chamber 12 via a motor bracket 33. Since the motor 31 is located outside the hot air chamber 12, the height of the motor bracket can be reduced. Preferably, the installation height of the motor bracket 33 is 12 mm.

[0034] like Figure 2As shown, in one embodiment of the present invention, a plurality of transverse ribs 43 are provided on the outer side of the baffle 4 (the side facing the heating chamber 11 ), and the ribs 43 can be formed by a pressing process, and the air outlet 41 is arranged in a long strip shape along the ribs 43 .

[0035] The utility model also provides a cooking device, comprising the above-mentioned hot air component.

[0036] like Figure 1 、 Figure 5 As shown, in one embodiment of the present invention, the cooking device includes an outer shell 5 and a heating liner 1 provided in the outer shell 5. The heating liner 1 is a component of the cooking device (such as an oven, a steam oven, etc.) for heating food. A heating cavity 11 is provided in the heating liner 1, and a heating element 2, such as a heating tube, is provided on the top of the heating cavity 11. The side wall of the heating liner 1 protrudes outward to form the above-mentioned hot air chamber 12. This embodiment is described by taking the left side of the heating liner 1 as an example, and can also be provided on the right side of the heating liner 1 without limitation. The baffle 4 is provided between the hot air chamber 12 and the heating cavity 11 to separate the two. The outer shell 5 can be provided with a door assembly 51 for taking food in and out.

[0037] The cooking device provided by the embodiment of the present invention, in addition to the advantages brought by the above-mentioned hot air component, designs the heating element 2 inside the heating chamber 11, which can achieve faster temperature rise. Combined with the fan system, it can not only meet the requirements of rapid temperature rise, but also realize the lightweight fan system and reduce costs. In addition, when the fan 3 in the hot air chamber 12 is not working, it is a pure baking mode, which can reduce the coordinated work of the fan 3 and the heating element 2, thereby reducing the noise and energy consumption of the appliance, and improving the economy and environmental protection of the appliance.

[0038] In a preferred embodiment of the present invention, the air outlet 41 of the baffle 4 is directed toward the heating element 2. This allows the air blown out from the hot air chamber 12 to directly blow onto the heating element 2 at the top of the heating chamber 11, achieving good heat exchange with the heating element 2, improving heat exchange efficiency, and rapidly increasing the temperature in the heating chamber 11. Furthermore, the angle between the direction of the air outlet 41 and the horizontal direction is 30-60°. Since some hot air will flow upward through the outer side of the baffle 4, in order to reduce wind resistance at the air outlet 41, the angle between the direction of the air outlet 41 and the horizontal direction is 45°.

[0039] To further improve heating efficiency and the rate of temperature rise within the heating chamber 11, in one embodiment of the present invention, a heating element, such as a heating tube or burner, is also provided at the bottom of the heating chamber 11. Thus, the air blown out of the hot air chamber 12 is heated by the heating element 2 at the top of the heating chamber 11, then heated again at the bottom of the heating chamber 11 and circulated back into the hot air chamber 12. Each cycle is heated twice, significantly improving heating efficiency and the rate of temperature rise within the heating chamber 11.

[0040] like Figure 5 As shown, in one embodiment of the present invention, the cooking device further comprises a housing 6, the housing 5 is disposed in the housing 6, an air inlet 61 is provided at the bottom of the housing 6, and a smoke exhaust port 62 is provided at the top of the housing 6. A smoke exhaust fan 63 can be disposed in the smoke exhaust port 62 to exhaust smoke generated during cooking to the outside.

[0041] The cooking equipment provided by the present invention also includes other necessary insulation components, electronic control components, range hood components, etc., which are existing technologies and will not be described in detail.

[0042] The cooking device provided by the embodiment of the present invention adopts a split hot air component, and the fan system is far away from the heating element. Compared with the traditional hot air component with its own heating tube, the system temperature rise is lower and the motor is safer. At the same time, it can reduce the complexity of the system, reduce the thickness of the system, and improve space utilization. During operation, since only the side fans can be enabled and the top heating element is not enabled, the noise generated by the coordinated work of the fan and the heating element can be effectively reduced, thereby improving the user experience. At the same time, since the long-term use of the heating element is reduced, the energy consumption of the appliance can also be reduced, and other surface heating tubes can be shared to improve the utilization rate of the device, reasonably distribute the work, and reduce costs. When traditional grilling is required, the fan system is not started, and only the upper and lower grilling tubes need to be turned on.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
