Induction cooker for making steamed buns with directional air duct-based heat dissipation

Abstract

This utility model discloses a heat-dissipating induction cooker for steamed buns with a directional air duct, including an induction cooker body, a partition plate, and an air duct assembly. The air duct assembly includes a cooling fan, a perforated air inlet plate, and air guides. A guide pipe is provided on the top of the perforated air inlet plate, and the air guides include multiple guide vanes arranged in sequence. The deflection angle of the multiple guide vanes toward the cooling fan decreases sequentially. The partition plate, together with the guide pipe and the air guides, precisely divides the air-cooled airflow into upper and lower layers. The "lower airflow" directly reaches the high-heat-generating heating core, while the "upper airflow" covers the heating coil specifically for the steamed bun side. Furthermore, the deflection angle of the multiple guide vanes toward the cooling fan decreases sequentially. In the initial state, the airflow can be guided to flow in a forward direction along the path of "perforated air inlet plate → guide pipe → partition plate → cooling fan," avoiding turbulent collisions inside the device and effectively dissipating heat from the inside of the induction cooker body.

Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic cooker technology, and in particular relates to a heat dissipation type induction cooker for steamed buns based on a directional air duct. Background Technology

[0002] As a traditional delicacy, Guobianmo (a type of flatbread) requires continuous and even heating of the edge of the pot during cooking to ensure the flatbread is thoroughly cooked and crispy. Traditional Guobianmo stoves typically use charcoal heating, with the stove itself primarily constructed of brick and the pot mainly made of cast iron. Charcoal is placed inside the stove's firebox, and its heat is used to heat the pot and cook the flatbread. Induction cookers for Guobianmo, however, have a heating element and coil inside. The heating element heats the pot via the electromagnetic heating coil. This method is widely used due to its rapid temperature rise and even heating. However, because of the rapid heating, the heating coil and heating element inside the induction cooker generate a large amount of heat. Fan-based cooling is ineffective, and the generated heat radiates to the outer surface of the cooker, affecting the user's operation. Utility Model Content

[0003] This utility model addresses the problems in the prior art by proposing the following technical solution: A heat-dissipating induction cooker for steamed buns based on a directional air duct includes: an induction cooker body, a partition plate, and an air duct assembly. The top and bottom of the partition plate are respectively provided with a heating coil and a heating element. The partition plate is located inside the induction cooker body and divides the air-cooled airflow of the air duct assembly into upper and lower layers. The upper layer of airflow dissipates heat to the heating coil at the top, and the lower layer of airflow dissipates heat to the heating element at the bottom. The air duct assembly includes a cooling fan, a perforated air inlet plate, and a guide component. The cooling fan is located at the rear of the induction cooker body, and the perforated air inlet plate is located at the bottom of the induction cooker body. The top of the hollow air inlet plate is provided with a guide tube, and the guide component is located inside the guide tube. The guide component includes a plurality of guide vanes arranged in sequence, and the deflection angle of the plurality of guide vanes toward the cooling fan decreases sequentially.

[0004] As a preferred embodiment of the above technical solution, the deflection angle range of the plurality of guide vanes is 8°-45°, and the deflection angle difference between two adjacent guide vanes is 6°-10°.

[0005] As a preferred embodiment of the above technical solution, the guide component further includes a reciprocating rack and multiple rotating shafts. The rotating shafts are fixedly connected to the corresponding guide vanes. Multiple gears are meshed on one side of the rack, and the gears are coaxially and fixedly connected to the rotating shafts.

[0006] As a preferred embodiment of the above technical solution, the air duct assembly further includes a driving component, which is fixedly installed on the surface of the guide tube. The output end of the driving component is fixedly connected to the end of the rack away from the cooling fan. The driving component is an electric push rod.

[0007] As a preferred embodiment of the above technical solution, the perforated groove of the perforated air inlet plate is elongated, and a dustproof mesh is provided inside the perforated groove of the perforated air inlet plate.

[0008] The beneficial effects of this utility model are as follows: 1. The heat-dissipating induction cooker for steamed buns based on directional air duct described in this utility model divides the interior of the cooker body into a bottom heating core area and a top heating coil area through a partition plate. With the directional guidance of the guide pipe and guide components, the air-cooled airflow is precisely divided into upper and lower layers. The "lower layer airflow" directly reaches the high-heat-generating heating core, preventing it from aging due to heat accumulation. The "upper layer airflow" covers the heating coil for the steamed bun side, preventing heat radiation from causing the surface of the cooker body to overheat and affect the user's operation. In addition, the deflection angle of multiple guide plates toward the cooling fan decreases sequentially. In the initial state, the airflow can be guided to flow in the direction of "hollow air inlet plate → guide pipe → partition plate → cooling fan", avoiding turbulent collision of airflow inside the device, reducing ineffective heat dissipation, greatly improving heat exchange efficiency, and effectively dissipating heat inside the cooker body. 2. The heat dissipation induction cooker for pot-side steamed buns based on directional air duct described in this utility model can drive all gears to rotate synchronously by reciprocating the rack and pinion, thereby simultaneously adjusting the deflection angle of multiple guide vanes. When the temperature is high, the angle of the guide vanes is reduced to increase the airflow to the heating element for rapid heat dissipation, while when the angle of the guide vanes is increased, the focus is on accelerating the heat dissipation of the internal space of the induction cooker body, realizing "on-demand supply" and adapting to the differentiated heat dissipation needs of the unique dual heating components of the pot-side steamed bun induction cooker.

[0011] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0012] Figures 1-3 The induction cooker for steamed buns with heat dissipation based on directional air duct includes: an induction cooker body 10, a partition plate 20, and an air duct assembly. The top and bottom of the partition plate 20 are respectively provided with heating coils and heating elements. The partition plate 20 is located inside the induction cooker body 10 and divides the air-cooled airflow of the air duct assembly into upper and lower layers. The upper layer of airflow dissipates heat to the heating coil at the top, and the lower layer of airflow dissipates heat to the heating element at the bottom. The air duct assembly includes a cooling fan 30, a hollow air inlet plate 40, and a guide plate 60. The cooling fan 30 is located on the rear side of the induction cooker body 10, and a control panel is provided on the front side of the induction cooker body 10. The hollow air inlet plate 40 is located at the bottom of the induction cooker body 10. The top of the hollow air inlet plate 40 is provided with a guide pipe 50, and the guide component 60 is located inside the guide pipe 50. The guide component 60 includes a plurality of guide vanes 61 arranged in sequence, and the deflection angle of the plurality of guide vanes 61 toward the cooling fan 30 decreases in sequence.

[0013] The deflection angle range of the plurality of guide vanes 61 is 8°-45°, and the difference in deflection angle between two adjacent guide vanes 61 is 6°-10°.

[0014] The partition plate 20 divides the interior of the induction cooker body 10 into a bottom heating core area and a top heating coil area. With the directional guidance of the guide pipe 50 and the guide component 60, the air-cooled airflow is precisely divided into upper and lower layers. The "lower airflow" directly reaches the high-heat-generating heating core to prevent it from aging due to heat accumulation. The "upper airflow" covers the heating coil dedicated to the pot side to prevent heat radiation from causing the surface of the induction cooker body 10 to overheat and affect the user's operation. In addition, the deflection angle of multiple guide vanes 61 toward the cooling fan 30 decreases sequentially. In the initial state, the airflow can be guided to flow in the direction of the hollow air inlet plate 40 → guide pipe 50 → partition plate 20 → cooling fan 30, avoiding the airflow from turbulent collision inside the device, reducing ineffective heat dissipation, greatly improving heat exchange efficiency, and effectively dissipating heat inside the induction cooker body 10.

[0015] Figures 2-3 In the process, the hollowed-out groove of the hollowed-out air inlet plate 40 is set in a long strip shape, and a dustproof net is set inside the hollowed-out groove of the hollowed-out air inlet plate 40.

[0016] The guide member 60 also includes a reciprocating rack 62 and a plurality of rotating shafts 63. The rotating shafts 63 are fixedly connected to the corresponding guide vanes 61. A plurality of gears 64 are meshed on one side of the rack 62. The gears 64 are coaxially fixedly connected to the rotating shafts 63.

[0017] The air duct assembly also includes a drive component 70, which is fixedly installed on the surface of the guide tube 50. The output end of the drive component 70 is fixedly connected to the end of the rack 62 away from the cooling fan 30. The drive component 70 is an electric push rod or other reciprocating drive device.

[0018] By driving the rack 62 to move back and forth, all gears 64 can be rotated synchronously, thereby adjusting the deflection angle of multiple guide vanes 61 at the same time. When the temperature is high, the angle of the guide vanes 61 is reduced to increase the airflow to the heating element for rapid heat dissipation. When the angle of the guide vanes 61 is increased, the focus is on accelerating the heat dissipation of the internal space of the induction cooker body 10, realizing "on-demand supply" and adapting to the differentiated heat dissipation needs of the dual heating components unique to the pot-side steamed bun induction cooker.

[0019] Working principle: The operating control panel activates the cooling fan 30. Outside air, filtered by the dust filter, enters the perforated air intake plate 40. As the airflow passes through the ductwork, it is guided by multiple guide vanes 61 with decreasing deflection angles towards the cooling fan 30, converging towards the cooling fan 30. The airflow is divided into upper and lower layers at the partition plate 20. The "upper layer airflow" passes the top heating coil position, such as... Figure 2 In the diagram, direction A represents the flow direction of the "upper airflow," while the "lower airflow" passes through the bottom heating element. Figure 2 In the diagram, direction B is the direction through which the "lower airflow" flows, completing the basic heat dissipation inside the induction cooker body 10; When cooking at high temperatures, the heating element generates more heat. The control panel controls the electric push rod to move the rack 62, which in turn drives the gear 64 to rotate. This reduces the deflection angle of the guide vane 61, increasing the airflow to the heating element and improving its cooling efficiency. When heat dissipation is needed for the heating coil inside the induction cooker body 10, the electric push rod pulls the rack 62 to move in the opposite direction, increasing the deflection angle of the guide vane 61. This increases the airflow to the heating coil at multiple frequencies in a short time, reducing heat accumulation above the inside of the induction cooker body 10 and preventing overheating of the outer surface of the induction cooker body 10 due to heat radiation, which could affect the user's use.

[0020] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
