Description

Technical Field

[0001] This utility model relates to the field of induction cookers, and in particular to an induction cooker with dual air duct cooling and heat dissipation. Background Technology

[0002] Currently, most induction cookers on the market place the heating coil on the upper layer, while the cooling duct is arranged on the lower layer, using airflow circulation in the lower layer to dissipate the heat generated by the heating coil. However, when the induction cooker is operating in high-power single-burner or multi-burner heating mode, due to the high power and rapid heat accumulation, the temperature of the heating coil and electronic control components can easily rise sharply and even exceed the safe range. This can lead to problems such as coil burnout, circuit board damage, or premature shutdown of the device, seriously affecting the product's lifespan and the user's actual experience.

[0003] Based on the above, existing induction cookers need further improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing induction cookers and provide a dual-airflow cooling induction cooker. By using an isolation component to enclose and form upper and lower cooling airflow channels inside the induction cooker, the airflow passes through both the heating coil on the upper layer and the electronic control components on the lower layer, dissipating heat from both the heating coil and the electronic control components simultaneously. This prevents the rapid accumulation of heat during high-power operation of the induction cooker, which could lead to component damage, and extends the product's service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-air duct cooling and heat dissipation induction cooker, including a cover plate and a body, wherein the body is provided with an isolation component, an air inlet and an air outlet, the isolation component includes an isolation plate and a baffle, the baffle surrounds the isolation plate, the upper wall of the isolation plate, the inner wall of the body, the inner wall of the baffle and the cover plate surround to form an upper air duct, the lower wall of the isolation plate, the inner wall of the baffle and the inner wall of the body surround to form a lower air duct, and the air inlet and the air outlet are both connected to the upper air duct and the lower air duct.

[0006] This invention utilizes an isolation component to enclose two independent cooling air ducts inside the induction cooker. This allows airflow to simultaneously pass over the upper heating coil and the lower electronic control components, achieving coordinated heat dissipation for both and effectively preventing component damage caused by rapid heat accumulation during high-power operation. Compared to existing technologies, this dual-air-duct cooling induction cooker significantly improves heat dissipation efficiency and extends product lifespan.

[0007] Preferably, an air inlet guide plate and an air outlet guide plate are arranged opposite to each other on the isolation plate. A vortex fan is provided on the upper side of the air inlet. The air inlet guide plate is connected to the outlet of the vortex fan. The air outlet guide plate is located on the side close to the air outlet. The air inlet guide plate and the air outlet guide plate guide the airflow blown out from the vortex fan. The air inlet guide plate causes the airflow to flow to the upper or lower side of the isolation plate, and the air outlet guides the airflow to the air outlet.

[0008] Preferably, the vortex fan has two outlets, including a first outlet and a second outlet located below the first outlet. The upper air duct is connected to the first outlet, and the lower air duct is connected to the second outlet.

[0009] Preferably, the isolation assembly further includes guide fins, which are disposed on the upper side of the air inlet guide plate.

[0010] Preferably, the airflow guide fins are provided in a plurality of manners, and the spacing between adjacent airflow guide fins increases from the end closer to the vortex fan to the end closer to the isolation plate; the airflow is separated by a plurality of airflow guide fins, the airflow passage area is reduced, the airflow speed is increased, and the heat dissipation effect is improved.

[0011] Preferably, the baffle has a bent connecting part at one end near the vortex fan, and the connecting part has a notch. The baffle plate divides the notch into a first inlet and a second inlet. The first inlet corresponds to the first outlet, and the second inlet corresponds to the second outlet. The airflow enters the upper duct through the first outlet and the first inlet in sequence, or enters the lower duct through the second outlet and the second inlet in sequence.

[0012] Preferably, the main body further includes a bottom shell and a fixing base. The bottom shell is configured as a one-way open cavity. The fixing base is disposed on the lower side of the isolation component and is connected to the baffle to form the lower air duct. An electronic control board is installed on the fixing base. Installing the electronic control board in the lower air duct helps to dissipate heat from the electronic control board.

[0013] Preferably, the fixing base has connecting portions extending upward on both sides, and the connecting portions are connected to the baffle.

[0014] Preferably, the main body further includes a switch plate, which is mounted on one side of the vortex fan via a switch bracket, and a heating coil is mounted on the upper side of the isolation plate.

[0015] Preferably, a heating coil is provided on the upper side of the isolation plate; the heating coil is installed in the upper air duct so that the airflow directly dissipates heat from the heating coil, thereby the heat generated by the heating coil can be discharged in time, improving the heat dissipation efficiency of the heating coil.

[0016] Preferably, the air inlet guide plate and the air outlet guide plate are designed as arc-shaped curved plates. Since the height of the first outlet and the air outlet is less than the height of the isolation plate, the air inlet guide plate is used to lift the airflow, and the air outlet guide plate is used to lower the airflow. The arc design makes the airflow smoother and avoids the geometric change in the direction of airflow caused by the bend at the connection of the straight plates, which would cause the airflow speed to decrease.

It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0027] See Figures 1 to 4 This embodiment discloses a dual-air duct cooling induction cooker 1, including a cover plate 2 and a body 3. The body 3 is provided with an isolation component 4, an air inlet 31 and an air outlet 32. The isolation component 4 includes an isolation plate 41 and a baffle 42. The baffle 42 surrounds the isolation plate 41. The upper wall of the isolation plate 41, the inner wall of the body 3, the inner wall of the baffle 42 and the cover plate 2 form an upper air duct 5. The lower wall of the isolation plate 41, the inner wall of the baffle 42 and the inner wall of the body 3 form a lower air duct 6. The air inlet 31 and the air outlet 32 ​​are both connected to the upper air duct 5 and the lower air duct 6.

[0028] See Figures 1 to 5 To guide airflow into the upper and lower air ducts or out of the air outlet 32, an air inlet guide plate 41 and an air outlet guide plate 412 are arranged opposite to each other on the isolation plate 41. A vortex fan 33 is provided on the upper side of the air inlet 31. The air inlet guide plate 411 is connected to the outlet of the vortex fan 33. The air outlet guide plate 412 is arranged on the side close to the air outlet 32.

[0029] See Figure 7 The vortex fan 33 has two outlets, including a first outlet 331 and a second outlet 332 located below the first outlet 331. The upper air duct 5 is connected to the first outlet 331, and the lower air duct 6 is connected to the second outlet 332. The vortex fan 33 in this design is a dual-outlet vortex fan 33, which separates the airflow and outputs it to the upper air duct 5 and the lower air duct 6.

[0030] See Figure 5 and Figure 7 The isolation component 4 also includes a guide fin 43, which is disposed on the upper side of the air inlet guide plate 411.

[0031] See Figure 7 The airflow guide fins 43 are provided in a plurality of units, and the spacing between adjacent airflow guide fins 43 increases from the end closer to the vortex fan 33 to the end closer to the isolation plate 41. Specifically, the airflow guide fins 43 are arranged perpendicular to the air inlet guide plate 411. In this design, the airflow guide fins 43 separate the airflow entering the upper air duct 5, and increase the airflow velocity by reducing the airflow passage area, thereby improving the heat dissipation efficiency.

[0032] See Figures 3 to 7The baffle 42 has a bent connecting portion 421 at one end near the vortex fan 33. The connecting portion 421 has a notch 422, and the partition plate 41 divides the notch into a first inlet 4221 and a second inlet 4222. The first inlet 4221 corresponds to the first outlet 331, and the second inlet 4222 corresponds to the second outlet 332. In this design, the connecting portion 421 is used to enclose the outlet of the vortex fan 33, and the notch is used to prevent airflow from entering the vortex fan 33. Airflow sequentially enters the upper duct through the first outlet 331 and the first inlet 4221, or sequentially enters the lower duct through the second outlet 332 and the second inlet 4222.

[0033] See Figures 1 to 6 In order to fix the electronic control board 36 on the body 3 and achieve heat dissipation, the body 3 also includes a bottom shell 34 and a fixing seat 35. The bottom shell 34 is a one-way open cavity. The fixing seat 35 is located on the lower side of the isolation component 4 and is connected to the baffle 42 to form the lower air duct 6. The electronic control board 36 is installed on the fixing seat 35.

[0034] See Figures 3 to 6 The fixing base 35 has connecting parts 351 extending upward on both sides, and the connecting parts 351 are connected to the baffle 42.

[0035] See Figures 3 to 6 The main body 3 also includes a switch plate 37, which is mounted on one side of the vortex fan 33 via a switch bracket 38, and a heating coil 39 is mounted on the upper side of the isolation plate 41.

[0036] See Figures 4 to 7 The inlet guide plate 411 and outlet guide plate 412 are designed as arc-shaped curved plates. In this design, the inlet guide plate 411 and outlet guide plate 412 allow the airflow to smoothly reach the upper side of the isolation plate 41 from the first inlet 4221 with a smaller height along an arc-shaped path, or allow the airflow to smoothly descend from the upper side of the isolation plate 41 to the outlet 32. Together with the isolation plate 41, they form a smooth upward airflow path 5, preventing the sudden drop in airflow velocity caused by the geometric abrupt change formed by the connection of straight plates, thereby reducing the heat dissipation efficiency.

[0037] See Figure 2 Specifically, the air inlet 31 is disposed on the lower wall of the bottom shell 34 and arranged in a circular shape, and the air outlet 32 ​​is strip-shaped and disposed on the side wall of the bottom shell 34 away from the air inlet 31.

[0038] This invention utilizes an isolation component 4 to enclose two independent heat dissipation ducts within the induction cooker 1, allowing airflow to simultaneously pass over the upper heating coil 39 and the lower electronic control components. This achieves coordinated heat dissipation for both, effectively preventing component damage caused by rapid heat accumulation during high-power operation. Compared to existing technologies, this invention's dual-duct cooling induction cooker 1 significantly improves heat dissipation efficiency and extends product lifespan.
