Referring to fig. 1 to 10, a first aspect of an embodiment of the present application provides a cooking apparatus.

The cooking device 100 may be an induction cooker, an electric ceramic cooker, an electric pressure cooker, etc., and the embodiment of the present application is described with reference to an induction cooker as an example, in which the heating member 140 is a coil disk.

As shown in fig. 1 and 2, the cooking device 100 includes a housing 110, wherein 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, the upper cover 111 is further provided with a panel 180, and the panel 180 may be a ceramic panel or a glass panel. The housing 110 has a receiving cavity 120, a heat dissipation fan 130 and a heating element 140 are disposed in the receiving cavity 120, and the heating element 140 is located on a side of the heat dissipation fan 130 away from the bottom wall of the lower cover 113, that is, the heating element 140 is located directly above the heat dissipation fan 130.

Specifically, the heat dissipation fan 130 has a first sub-portion 131, and an orthogonal projection of the first sub-portion 131 on the bottom wall of the lower cover 113 and an orthogonal projection of the heating element 140 on the bottom wall of the lower cover 113 do not overlap with each other, that is, the heat dissipation fan 130 is not completely covered by the heating element 140, and a part of the heat dissipation fan is exposed from directly below the heating element 140, and the exposed part is the first sub-portion 131. The bottom wall of the lower cover 113 is further provided with a wind shielding rib 150, and the wind shielding rib 150 is arranged around the periphery of the heat dissipation fan 130. Therefore, the wind blocking ribs 150 can enclose a wind storage area, so that the heat dissipation wind can be gathered in the wind storage area, and the heat dissipation fan 130 is located in the wind storage area, so that a large amount of heat dissipation wind can be blown out from the wind storage area continuously, and the heat dissipation efficiency of the heat dissipation fan 130 is improved.

The wind-shielding rib 150 surrounding the first section 131 has an extending portion 151, and the extending portion 151 extends away from the bottom wall of the lower cover 113. The height of the extension 151 is higher than that of the heating member 140. Here, the height of the extension 151 refers to the height of the top surface of the extension 151, the height of the heating member 140 refers to the height of the top surface of the heating member 140, and the top surface of the heating member 140 refers to the top surface of the wire-wound rib of the heating member 140.

It should be noted that the heat dissipation fan 130 in the embodiment of the present application is an axial flow fan. By making the orthographic projection of the first subsection 131 of the heat dissipation fan 130 on the bottom wall not coincide with the orthographic projection of the heating element 140 on the bottom wall, part of the heat dissipation air blown by the heat dissipation fan 130 can be blown out from the area where the first subsection 131 is located to the upper side. By extending the extending portion 151 of the wind shielding rib 150 in a direction away from the bottom wall, and the height of the extending portion 151 is higher than that of the heating member 140, the extending portion 151 can form an air guide member, so that the cooling air blown out from the area where the first sub-portion 131 is located flows vertically upwards along the air guide member, and after the cooling air is contacted with the panel 180, the cooling air turns around and can flow towards the upper surface of the heating member 140, the area between the heating member 140 and the panel 180 is cooled, the temperature of the upper surface of the heating member 140 is reduced, the heat dissipation effect of the heating member 140 is better, and the service life of the cooking device 100 is prolonged.

Specifically, as shown in fig. 8, the heat dissipation fan 130 has a second sub-portion 132, the second sub-portion 132 and the first sub-portion 131 together form the heat dissipation fan 130, and an orthographic projection of the second sub-portion 132 on the bottom wall of the lower cover 113 coincides with an orthographic projection of the heating element 140 on the bottom wall of the lower cover 113. The area of the orthographic projection of the first sub-section 131 on the bottom wall of the lower cover 113 is smaller than the area of the orthographic projection of the second sub-section 132 on the bottom wall of the lower cover 113.

It is to be understood that, in the embodiment of the present application, "the first section 131" refers to a portion of the heat dissipation fan 130 that is not shielded by the heating element 140, and "the second section 132" refers to a portion of the heat dissipation fan 130 that is shielded by the heating element 140. The heat dissipation wind blown from the first sub-section 131 is mainly used to dissipate heat from the upper surface of the heating element 140, the heat dissipation wind blown from the second sub-section 132 is mainly used to dissipate heat from the circuit board 160, and the circuit board 160 needs to dissipate more heat. The orthographic projection of the first subsection 131 is smaller than the orthographic projection of the second subsection 132, i.e. the first subsection 131 is smaller than the second subsection 132. In this way, the amount of the heat dissipation air blown out from the first sub-portion 131 is smaller than the amount of the heat dissipation air blown out from the second sub-portion 132, so that the flow direction distribution of the heat dissipation air blown out from the heat dissipation fan 130 is more reasonable, and the heat dissipation efficiency of the heat dissipation fan 130 is improved.

Specifically, as shown in fig. 2 and 7, the cooking device 100 further includes a circuit board 160, the circuit board 160 is located on a side of the heating element 140 close to the bottom wall of the lower cover 113, that is, the circuit board 160 is located directly below the heating element 140, and an orthogonal projection of the heating element 140 on the bottom wall of the lower cover 113 and an orthogonal projection of the heat dissipation fan 130 on the bottom wall of the lower cover 113 do not overlap with each other. Thus, the space utilization rate of the receiving cavity 120 can be improved, and the size of the cooking device 100 can be made smaller.

The air outlet of the second section 132 faces the heat generating region of the circuit board 160. Because the heating area of the circuit board 160 generates a large amount of heat, and the air outlet is over against the heating area, the heat dissipation air can directly flow to the heating area to dissipate heat of the high-temperature components of the circuit board 160, so that the heat dissipation effect of the circuit board 160 is better.

Specifically, as shown in fig. 7, 8 and 9, the wind shielding rib 150 provided around the outer periphery of the second section 132 has a notch, and the notch forms a wind outlet. Thus, the structure of the wind screen 150 can be simplified, and the difficulty in manufacturing the cooking device 100 can be reduced.

In one possible embodiment, the circuit board 160 has a first heat-generating region 161 and a second heat-generating region 162 arranged at intervals, the notches include a first notch 152 and a second notch 153, and the first notch 152 and the second notch 153 are arranged at intervals along the circumferential direction of the wind-shielding rib 150. The first notch 152 is opposite to the first heat generating region 161, and the second notch 153 is opposite to the second heat generating region 162.

It is understood that an Insulated Gate Bipolar Transistor (IGBT) may be disposed in the first heat-generating region 161, and a heat sink may be disposed on the IGBT for increasing a heat-dissipating area of the IGBT. A capacitor, a bridge stack, etc. may be disposed in the second heat generating region 162. The first heat generating region 161 generates a larger amount of heat than the second heat generating region 162, and thus the size of the first notch 152 may be larger than the size of the second notch 153, so that the amount of the heat dissipating wind flowing through the first heat generating region 161 is larger.

As shown in fig. 7, in the embodiment of the present application, the heat dissipation air blown by the heat dissipation fan 130 has three flow directions, which flow to the first heat generation region 161, the second heat generation region 162 and directly above the first sub-portion 131. The structure can ensure that the cooling air blown by the cooling fan 130 is respectively directed to the first heating area 161, the second heating area 162 and the upper surface of the heating element 140 for cooling, thereby improving the utilization rate of the cooling air and the cooling efficiency of the cooling fan 130.

In a possible embodiment, as shown in fig. 7 and 9, a first air guiding plate 171 and a second air guiding plate 172 are further disposed in the accommodating cavity 120, the first air guiding plate 171 and the second air guiding plate 172 are respectively located at two opposite sides of the first notch 152 and are both connected to the wind shielding rib 150, and the first air guiding plate 171 and the second air guiding plate 172 both extend toward the first heat generating area 161. A portion of the first heat generation region 161 is located between the first air deflector 171 and the second air deflector 172. In addition, a portion of the outer edge of the circuit board 160 may be provided with a third air deflector 173. The first air deflector 171, the second air deflector 172 and the third air deflector 173 are arranged to guide the flow of the heat dissipation wind so that the heat dissipation wind can flow through the heat generation area; on the other hand, the heat dissipation air can be gathered, and the heat dissipation efficiency of the heat dissipation air is improved.

In one possible embodiment, as shown in fig. 3 and 4, the end of the extension 151 is provided with a groove 1511, and the groove 1511 divides the extension 151 into at least two sub-extensions 1512.

It is understood that the end of the extension 151 is liable to collide with the panel 180 due to the jolt or oscillation of the cooker 100 during the transportation of the cooker 100, resulting in the breakage of the panel 180. Therefore, the groove 1511 may reduce the structural strength of the extension 151, and the extension 151 may be deformed to prevent the panel 180 from being broken when the end of the extension 151 collides with the panel 180.

In one possible embodiment, as shown in FIG. 4, the groove 1511 has a width W between 0.5-1.5mm, wherein the width W may be 0.5mm, 1mm, or 1.5 mm. If the width W is less than 0.5mm, the structural strength of the extension portion 151 is less reduced, and the extension portion 151 is not easily deformed. If the width W is greater than 1.5mm, more heat dissipation air is likely to leak from the groove 1511, which reduces the amount of heat dissipation air flowing through the surface of the heating element 140 and reduces the heat dissipation effect of the heating element 140.

In one possible embodiment, as shown in FIG. 4, the depth L of the groove 1511 is between 8-12mm, wherein the depth L may be 8mm, 10mm, or 12 mm. If the depth L is less than 8mm, the structural strength of the extension portion 151 is less reduced, and the extension portion 151 is not easily deformed. If the depth L is greater than 12mm, more heat dissipation air is likely to leak from the groove 1511, which reduces the amount of heat dissipation air flowing through the surface of the heating element 140 and reduces the heat dissipation effect of the heating element 140.

In one possible embodiment, the ratio of the orthographic projection area of the first sub-portion 131 on the bottom wall of the lower cover 113 to the orthographic projection area of the heat dissipation fan 130 on the bottom wall of the lower cover 113 is between 5% and 10%, wherein the ratio of the two areas may be 5%, 7% or 10%. Therefore, on one hand, the air quantity of the cooling air flowing out to the heating element 140 from the area where the first sub-part 131 is located can be optimized, and the cooling efficiency of the cooling fan 130 is improved; on the other hand, the layout of the heat dissipation fan 130 can be more reasonable, and the size of the cooking device 100 can be reduced to the maximum extent.

In one possible embodiment, as shown in fig. 4, the height difference H between the extension part 151 and the heating member 140 is between 1 and 3mm, wherein the height difference H may be 1mm, 2mm or 3 mm. The height difference is within the above range, so that the heat dissipating wind can be guided, the flow of the whole heat dissipating wind to the upper surface of the heating member 140 can be ensured to the maximum extent, and the influence of the contact between the extending portion 151 and the panel 180 on the assembly of the panel 180 can be avoided.

Specifically, as shown in fig. 10, an air inlet area 1131 is disposed on the bottom wall of the lower cover 113, a plurality of air inlet holes 1132 are disposed in the air inlet area 1131 at intervals, and an orthogonal projection of the heat dissipation fan 130 on the bottom wall of the lower cover 113 is located in the air inlet area 1131. The lower cover 113 is further provided with air outlets 1133, and the air outlets 1133 are located on the side wall of the lower cover 113 opposite to the first notch 152 and on the side wall of the lower cover 113 opposite to the second notch 153.

It can be understood that the air inlet area 1131 is located in the area enclosed by the wind blocking rib 150, so that the heat dissipating air enters from the air inlet holes 1132 of the air inlet area 1131 and is gathered in the air storage area enclosed by the wind blocking rib 150, and the heat dissipating fan 130 blows the gathered heat dissipating air continuously to the component to be heat dissipated. Because a large amount of heat dissipation wind flows out from first breach 152 and second breach 153, consequently, exhaust 1133 is relative with first breach 152 and second breach 153, can make the heat dissipation wind more unobstructed in holding chamber 120 flows, improves radiator fan 130's radiating efficiency.

On the basis of the first aspect, a second aspect of the embodiments of the present application provides a cooking appliance, which includes a pot and the cooking device 100 described above. The cooking appliance may be an electromagnetic grill.

According to the cooking appliance provided by the embodiment of the application, the orthographic projection of the first sub-part 131 of the heat dissipation fan 130 on the bottom wall is not overlapped with the orthographic projection of the heating element 140 on the bottom wall, so that part of heat dissipation air blown out by the heat dissipation fan 130 can be blown out upwards from the area where the first sub-part 131 is located. By extending the extending portion 151 of the wind shielding rib 150 in a direction away from the bottom wall, and the height of the extending portion 151 is higher than that of the heating member 140, the extending portion 151 can form an air guide member, so that the cooling wind blown out from the area where the first sub-portion 131 is located flows along the direction of the upper surface of the heating member 140 along the air guide member, thereby cooling the upper surface of the heating member 140, improving the cooling effect of the heating member 140, and prolonging the service life of the cooking appliance.
