Description

Technical field

[0001] The utility model relates to an electromagnetic cooker with good heat dissipation performance. [Background Technology]

[0002] An induction cooker is a common household appliance used for heating. Its body is equipped with components such as an electromagnetic coil, a fan, and a circuit board. When the induction cooker is in operation, the fan generates wind pressure by driving air flow, dissipating heat. However, since the fan is typically located on one side of the electromagnetic coil, it blows air drawn in from outside the cooker toward the side of the coil, removing only a portion of the heat. This results in less than ideal heat dissipation, causing electronic components to overheat, impacting the cooker's performance and service life. To overcome these shortcomings, some designs are currently available on the market, such as the induction cooker disclosed in Chinese invention patent application number 201210098851.5. These designs increase the number of fans or their rotational speed to increase the amount of heat dissipated. However, this also increases fan noise and costs.

[0003] Therefore, the present invention is just based on above deficiency and produces. [Utility Model Content]

When the wind enters the large end of the air inlet channel from the air inlet and then flows out through the small end of the air inlet channel, the air in the air inlet channel is compressed, thereby increasing the flow speed of the airflow entering the fan and increasing the air volume entering the fan per unit time, thereby increasing the heat dissipation air volume and improving the heat dissipation efficiency.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1 to 4 As shown, an induction cooker with good heat dissipation performance includes a base 1, the base 1 is provided with an air inlet 11, a fan 2 that can suck air from the air inlet 11 into the base 1, and an air inlet channel 12 connecting the air inlet 11 and the fan 2, the fan 2 is provided with a first side air outlet 21, and one side of the first side air outlet 21 is provided with an electromagnetic wire reel 3 mounted on the base 1, and a wind guide device located below the electromagnetic wire reel 3 is provided on the bottom wall of the base 1, and the wind guide device includes a main wind plate 15 provided on the base 1 and surrounding an air cavity 17 with the base 1, the air cavity 17 is provided with a top opening and a side opening 171, the electromagnetic wire reel 3 is above the top opening, the first side air outlet 21 is connected to the side opening 171, and the air cavity 17 is close to the first side air outlet 21. One side of the side air outlet 21 is provided with a first curved air guide surface 131 for guiding the wind blown out of the first side air outlet 21, and the air cavity 17 is also provided with a second curved air guide plate 14 for secondary guiding the wind guided by the first curved air guide surface 131. The second curved air guide plate 14 and the main air guide plate 15 form an air guide channel 16 at one end of which is connected to the first side air outlet 21 and guides the wind blown out of the first side air outlet 21. The other end of the air guide channel 16 guides the wind to converge with the wind guided for the second time by the second curved air guide plate 14 to form converged wind. The air cavity 17 is provided with a second curved air guide surface 132 that can block the converged wind and make part of the converged wind go upward and guide the remaining converged wind to the inner side of the second curved air guide plate 14. Figure 3 The direction of the middle arrow is the direction of airflow. When the wind blown out by the fan 2 passes through the first curved air guide surface 131 of the first curved air guide plate 13, the second curved air guide plate 14 and the main curved air guide plate 15, the cold air changes its flow direction to form a vortex, which increases the pressure of the airflow and the wind speed of the air outlet. Moreover, when the convergent wind guided by the main curved air guide plate 15 touches the back of the first curved air guide plate 13, part of the wind is directed to the electromagnetic wire reel 3, quickly taking away the heat of the electromagnetic wire reel 3 to lower the temperature, and part of the wind is directed to the second curved air guide plate 14 for circulation, which can increase the air volume of the next vortex wind, maximize the use of the air volume to achieve a good heat dissipation effect of the electromagnetic wire reel 3, reduce the number of fans used, reduce costs, and reduce the noise of the induction cooker.

[0023] Furthermore, the cross-sectional area of ​​the air inlet channel 12 gradually decreases from the air inlet 11 toward the fan 2. When air enters the large end of the air inlet channel 12 from the air inlet 11 and then flows out through the small end of the air inlet channel 12, the air in the air inlet channel 12 is compressed, increasing the flow rate of the airflow into the fan 2 and increasing the air volume entering the fan 2 per unit time, thereby increasing the heat dissipation volume and improving the heat dissipation efficiency.

[0024] Specifically, the air inlet channel 12 is trapezoidal, and a plurality of air inlets 11 are provided and arranged on the surface where the lower base of the trapezoid is located. The upper base of the trapezoid is open, and the fan 2 is installed at the opening.

[0025] In the present invention, the main air guide plate 15 includes an arc segment 151 and an extension segment 152 provided at both ends of the arc segment 151 and extending to the edge of the first side air outlet 21 .

[0026] Specifically, a first curved air guide plate 13 extending toward the electromagnetic wire reel 3 is provided on the bottom wall of the base 1, and the first curved air guide surface 131 and the second curved air guide surface 132 are respectively provided on both sides of the first curved air guide plate 13. The bending direction of the first curved air guide plate 13 is the same as the rotation direction of the fan 2, and the bending direction of the second curved air guide plate 14 and the curved segment 151 is opposite to the rotation direction of the fan 2.

[0027] Specifically, the height of the main air guide plate 15 is higher than that of the first curved air guide plate 13 and the second curved air guide plate 14, so that the wind cavity 17 formed by the main air guide plate 15 and the bottom wall of the base 1 can gather the wind blown out by the fan as much as possible to prevent the wind from blowing to places where heat dissipation is not required, while not affecting the guiding effect of the first curved air guide plate 13 and the second curved air guide plate 14 on the wind generated by the fan, so that the air output generated by the fan can be fully utilized.

[0028] In the present invention, the base 1 is provided with an induction cooker mainboard 4 electrically connected to the fan 2 and the electromagnetic coil 3. The fan 2 is provided with a second side air outlet 22 that can blow part of the air toward the induction cooker mainboard 4. The air blown out of the second side air outlet 22 removes the heat generated by the electrical components of the induction cooker mainboard, preventing the electronic components from overheating.

[0029] Specifically, a heat dissipation vent 18 is provided on the side wall of the base 1 for discharging the wind flowing through the electromagnetic wire reel 3 and the induction cooker mainboard. The hot wind carrying heat can be discharged from the induction cooker through the heat dissipation vent 18 and will not accumulate in the induction cooker.
