The cooking device 100 may be an induction cooker, an electric ceramic cooker, an electric pressure cooker, or the like, and the embodiment of the present application will be described with reference to an induction cooker as an example.

As shown in fig. 1, 2 and 3, the cooking device 100 includes a housing 110, the housing 110 has a receiving cavity 114, a heat dissipation fan 120 and a circuit board 130 are disposed in the receiving cavity 114, and the circuit board 130 has a heating element 131. The heat dissipation member 140 is attached to the heat element 131, and an included angle is formed between the extending direction of the heat dissipation member 140 and the extending direction of the circuit board 130, wherein in fig. 3, the a direction is the extending direction of the heat dissipation member 140, the b direction is the extending direction of the circuit board 130, and the included angle α between the two extending directions is an acute angle. The heat sink 140 has a heat dissipation channel 141, and an air outlet of the heat dissipation fan 120 faces the heat dissipation channel 141 of the heat sink 140.

It should be noted that the circuit board 130 may have a plurality of heating elements 131, such as: an IGBT (Insulated Gate Bipolar Transistor), a bridge stack, a capacitor, and the like. In the embodiment of the present application, the heating element 131 refers to a component with a high heating value, such as an IGBT and a bridge stack.

In the embodiment of the present application, by disposing the heat dissipation member 140 on the heating element 131, heat on the heating element 131 can be transferred to the heat dissipation member 140 and then dissipated through the heat dissipation member 140, thereby improving the heat dissipation effect of the heating element 131. By making the included angle between the extending direction of the heat sink 140 and the extending direction of the circuit board 130 be an acute angle, on one hand, the arrangement of components inside the induction cooker can be optimized, which is beneficial to the heat dissipation of the heat dissipation fan 120; on the other hand, the heat dissipation channel 141 of the heat dissipation member 140 can be directly opposite to the air outlet of the heat dissipation fan 120, so that the heat dissipation effect of the heat dissipation member 140 is the best, the heat dissipation performance of the cooking device 100 is enhanced, and the service life of the cooking device 100 is prolonged.

In the embodiment of the present application, the housing 110 includes an upper cover 111, a middle frame 112 and a lower cover 113, the middle frame 112 connects the upper cover 111 and the lower cover 113, and a panel 190 is disposed on a side of the upper cover 111 away from the middle frame 112. The accommodating chamber 114 is further provided with a heating element 200, and the heating element 200 is located right above the heat dissipation fan 120.

In one possible implementation, as shown in fig. 3, an orthogonal projection of the heat sink 140 on the bottom wall of the housing 110 covers an orthogonal projection of the heat generating element 131 on the bottom wall of the housing 110. Therefore, the heat dissipation member 140 has a large heat dissipation area, which is beneficial to dissipating heat from the heating element 131 quickly, so that the cooling effect of the heating element 131 is the best, thereby not only ensuring the working performance of the heating element 131, but also prolonging the service life of the heating element 131.

In one possible implementation manner, the heating element 131 is located at a side edge of the circuit board 130 on a side close to the heat dissipation fan 120, and an orthogonal projection of the heating element 131 on the bottom wall of the housing 110 and an orthogonal projection of the circuit board 130 on the bottom wall of the housing 110 are not overlapped with each other.

In this embodiment, the pins of the heating element 131 are welded to the electrical connection points of the circuit board 130, and the main body of the heating element 131 extends out of the board body of the circuit board 130, so that the heating element 131 is closer to the air outlet of the heat dissipation fan 120, and the heat dissipation effect of the heat dissipation member 140 can be improved to the greatest extent.

In one possible implementation, as shown in fig. 3, the heat generating element 131 includes a first heat generating element 1311 and a second heat generating element 1312, the circuit board 130 extends along the first direction b, and the first heat generating element 1311 and the second heat generating element 1312 are arranged at intervals along the first direction b at the side edge of the circuit board 130, wherein the first heat generating element 1311 is an IGBT and the second heat generating element 1312 is a bridge stack. By the arrangement mode, the IGBT and the bridge rectifier can be close to the air outlet of the cooling fan 120, and heat can be dissipated through the same heat dissipation piece 140.

In a possible implementation manner, the included angle is between 10 ° and 30 °, wherein the included angle may be 10 °, 20 ° or 30 °, and the included angle is within the above range, so that on one hand, more cooling air can be ensured to directly flow to the cooling channel 141 of the cooling member 140, and the cooling effect of the cooling member 140 is improved; on the other hand, the interference of the heat dissipation member 140 on other components is reduced to the maximum extent, and the influence on the arrangement of other components is avoided.

In one possible implementation, as shown in fig. 9, the heat dissipation member 140 includes a plurality of heat dissipation fins 142 arranged at intervals, and a heat dissipation channel 141 is formed between adjacent heat dissipation fins 142. The extending direction of the heat dissipating fins 142 is the same as the direction of the air outlet of the heat dissipating fan 120. Note that the extending direction of the heat dissipation fins 142 is the same as the extending direction of the heat dissipation member 140, and both are along the a direction in fig. 3. In this way, the flow direction of the heat dissipation channel 141 can be consistent with the direction of the air outlet, so that the flow resistance of the heat dissipation air in the heat dissipation channel 141 is reduced to the maximum extent, the heat dissipation air flows more smoothly in the heat dissipation channel 141, and the heat dissipation performance of the heat dissipation member 140 is improved.

It is understood that the heat dissipating fins 142 may be disposed on a heat dissipating case, which is wrapped on the outer surface of the heat generating member. The heat sink 140 is not limited in the embodiments of the present application.

In one possible implementation, an orthographic projection of the heat dissipation fan 120 on the side wall of the housing 110 coincides with at least a partial orthographic projection of the heat dissipation fins 142 on the side wall of the housing 110. In this way, the same height can be maintained to the greatest extent in the vertical direction between the heat dissipation fan 120 and the heat dissipation fins 142, so that it is ensured that part of the heat dissipation wind blown by the heat dissipation fan 120 can directly flow to the heat dissipation channel 141, and the heat dissipation efficiency of the heat dissipation fan 120 is ensured.

In a possible implementation manner, the heat sink 140 further includes a heat dissipation plate 143, the heat dissipation plate 143 is attached to the surface of the heat generating element, and the plurality of heat dissipation fins 142 are arranged at intervals on a side of the heat dissipation plate 143 away from the heat generating element 131. Thus, the structure of the heat sink 140 can be simplified, and the difficulty in manufacturing the heat sink 140 can be reduced. In the process of heat dissipation, the heat of the heating element 131 is firstly transferred to the heat dissipation plate 143, the heat dissipation plate 143 transfers a part of the heat to the heat dissipation fins 142, and the heat dissipation air flows through the heat dissipation channel 141 to take away the heat in the heat dissipation plate 143 and the heat dissipation fins 142.

In one possible implementation, as shown in fig. 9, the spacing W between adjacent heat dissipating fins 142 is between 1.5-3mm, wherein the spacing W may be 1.5mm, 2mm, or 3 mm. If the interval is greater than 3mm, the arrangement density of the heat dissipation fins 142 is small, and the heat dissipation effect of the heat dissipation member 140 cannot be maximized; if the distance is less than 1.5mm, the arrangement density of the heat dissipation fins 142 is large, and the heat dissipation channel 141 is small, which is not favorable for the heat dissipation air to flow from the heat dissipation channel 141.

In one possible implementation, as shown in FIG. 9, the height H of the heat sink fins 142 is between 10-15mm, wherein the height H may be 10mm, 12mm, 14mm, or 15 mm. If the height is less than 10mm, the heat dissipation area of the heat dissipation fins 142 is limited, and the heat dissipation effect of the heat dissipation member 140 cannot be maximized; if the distance is greater than 15mm, the height of the heat sink 140 is high, which may easily affect the arrangement of other components.

In one possible implementation, as shown in fig. 8, a supporting column 150 is provided on the bottom wall of the housing 110, and the heat sink 140 is fixed to the supporting column 150. The heat sink 140 may be fixed to the support column 150 by screws, so that the heat sink 140 may be firmly fixed to prevent the heat sink 140 from being dislocated when the cooker 100 is moved.

In one possible implementation, a plurality of fasteners 160 are further disposed on the heat sink 140, and the plurality of fasteners 160 respectively connect the first and second heat generating elements 1311 and 1312 and the circuit board 130 with the heat sink 140. Thus, on the one hand, the assembly stability of the heat sink 140 can be further improved, and on the other hand, the attachment stability of the first and second heat generating elements 1311 and 1312 to the heat sink 140 can be ensured, thereby ensuring the heat transfer stability and the heat dissipation efficiency of the heat sink 140.

In a possible implementation manner, as shown in fig. 7, a wind shielding rib 170 is disposed on the periphery of the heat dissipation fan 120, the wind shielding rib 170 has a first notch 171, the first notch 171 forms an air outlet, and in addition, the wind shielding rib 170 further has a second notch 172, and the second notch 172 may form a secondary air outlet.

Specifically, in the area surrounded by the wind shielding rib 170, the bottom wall of the lower cover 113 is provided with an air inlet 115, and in addition, the side wall of the lower cover 113 is provided with an air outlet 116. External air enters from the air inlet hole 115, passes through the heat dissipation fan 120, one part of dispersed hot air flows to the heat dissipation member 140 from the air outlet and then flows out from the air outlet hole 116, and the other part of dispersed hot air flows to the circuit board 130 from the secondary air outlet and then flows out from the air outlet hole 116.

Specifically, a first air guiding rib 181 and a second air guiding rib 182 are further arranged on the bottom wall of the casing 110, and the first air guiding rib 181 and the second air guiding rib 182 are respectively located on two sides of the first notch 171 and are respectively connected with the air guiding rib 170. The first air guiding rib 181 and the second air guiding rib 182 enclose an air guiding channel 183, and the heat dissipating member 140 is located in the air guiding channel 183. Therefore, the heat dissipation air flowing out of the air outlet can be ensured to flow to the heat dissipation piece 140 to the maximum extent, and the heat dissipation performance of the heat dissipation piece 140 is better.

In one possible implementation, the extending direction of the first air guiding rib 181 and the extending direction of the second air guiding rib 182 are both parallel to the extending direction of the heat sink 140. In this way, on one hand, the arrangement of the first air guiding ribs 181 and the second air guiding ribs 182 can be adapted to the arrangement of the heat dissipation member 140, and the arrangement of other components is prevented from being influenced; on the other hand, the flow direction of the heat radiation air in the air guide passage 183 can be made to coincide with the extending direction of the heat radiation fins 142, thereby reducing the flow resistance of the heat radiation air.

In one possible implementation, as shown in fig. 6, the circuit board 130 has a first end 132 and a second end 133 opposite to each other in the first direction, and the heat dissipation fan 120 and most of the heat dissipation members 140 are located on the same side of the circuit board 130, wherein a small portion of the heat dissipation members 140 are located directly above the circuit board 130. The heat dissipation fan 120 is disposed proximate the first end 132 and the heat dissipation member 140 is disposed proximate the second end 133. Thus, on the one hand, the arrangement of the circuit board 130, the heat dissipation fan 120 and the heat dissipation member 140 can be optimized; on the other hand, the heat dissipation performance of the heat dissipation fan 120 can be maximized, so that the heat dissipation efficiency of the heat dissipation fan 120 is improved.

A second aspect of the embodiments of the present application provides a cooking appliance, which includes a pot placed on a heating surface of the cooker 100, and the cooker 100 described above.

The cooking appliance provided by the application can improve the heat dissipation effect of the heating element 131 by arranging the heat dissipation member 140 on the heating element 131 of the cooking device 100. By making the included angle between the extending direction of the heat sink 140 and the extending direction of the circuit board 130 be an acute angle, on one hand, the arrangement of components inside the induction cooker can be optimized, which is beneficial to the heat dissipation of the heat dissipation fan 120; on the other hand, the heat dissipation channel 141 of the heat dissipation member 140 can be directly opposite to the air outlet of the heat dissipation fan 120, so that the heat dissipation effect of the heat dissipation member 140 is the best, the heat dissipation performance of the cooking device 100 is enhanced, and the service lives of the cooking device 100 and the cooking appliance are prolonged.
