In one possible implementation, referring to fig. 7 and 8, the housing cavity further has a power board mounting area 115, the inner wall surface of the lower cover 11 is further provided with a third wind shielding rib 60, the third wind shielding rib 60 is located between the power board mounting area 115 and the fan cavity 113, and the third wind shielding rib 60 is connected to the first wind shielding rib 40.

In one possible implementation, a portion of the second wind deflector 50 is located between the wind collection chamber 114 and the power panel mounting region 115, i.e., the power panel mounting region 115 is adjacent to the fan chamber 113, and the power panel mounting region 115 is adjacent to the wind collection chamber 114.

In one possible implementation, referring to fig. 7 and 8, a notch 90 is formed at a position where an end of the second wind shielding rib 50 near the power panel mounting region 115 is connected to the first wind shielding rib 40. The notch 90 can increase the speed and the wind power entering the wind collecting cavity 114 of the wind direction in the fan cavity 113, and is beneficial to improving the heat dissipation effect of the heating plate 20 on the upper side of the wind collecting cavity 114.

The notch rib part 51 has a structure with a height lower than that of the second wind shielding rib 50, and the height of the first step part 41 is smaller than that of the first wind shielding rib 40, so that the top surface of the first step part 41 and the top surface of the notch rib part 51 become the bottom surfaces of the notches 90, the blocking effect on wind is reduced at the positions of the first step part 41 and the notch rib part 51, the wind blown by the fan 30 is easier to enter the wind collecting cavity 114 through the notches 90, the wind force at the position of the notches 90 is more concentrated to the wind collecting cavity 114, and the utilization rate of the wind is improved.

With this structure, the flow of the air in the power panel mounting region 115 into the air collecting chamber 114 can be blocked, thereby ensuring the heat radiation effect of the power panel 92 mounted in the power panel mounting region 115.

The separation rib 52 can be in a V shape, the tip end of the separation rib 52 is connected with the notch rib part 51, the two wings of the separation rib 52 guide wind to the wind collecting cavity 114 and the power panel mounting area 115 respectively, cold wind is reasonably distributed, and the heat dissipation effect of the cooking equipment is improved.

In one possible implementation, the height of the first step 41 is greater than the height of the third wind deflector rib 60, and the height of the first step 41 is less than the height of the first wind deflector rib 40.

In one possible embodiment, referring to FIGS. 8 and 15, the height of the second wind shielding rib 50 is greater than the height of the first step 41, and the difference in height between the second wind shielding rib 50 and the first step 41 is H2, wherein 5 mm.ltoreq.H2.ltoreq.12 mm.

In one possible embodiment, the height of the top surface of the first step portion 41 coincides with the height of the top surface of the notch rib portion 51, the height of the top end surface of the first step portion 41 is determined according to the height of the top end surface of the second wind shielding rib 50, and the difference in height between the second wind shielding rib 50 and the first step portion 41 is 5mm, 6mm, 8mm, 10mm or 12mm.

In one possible implementation, H2 may be 5mm, 7mm, 8mm, 10mm or 12mm.

In one possible embodiment, since a part of the wind entering the wind collecting chamber 114 moves along the first wind shielding rib 40, even though the part of the wind is weak when guided to be collected in the wind collecting region A1, in order to better guide more wind to blow to the bottom of the region where the temperature rise of the heating pan 20 is highest, referring to fig. 9, the inner wall surface of the lower cover 11 is further provided with a guide rib 70, and the first end of the guide rib 70 is connected to the position where the first wind shielding rib 40 and the first step 41 are connected, and the second end of the guide rib 70 extends into the wind collecting chamber 114.

In one possible implementation, the guide rib 70 has a certain length and is biased toward a side away from the power panel mounting area 115, thereby better guiding the wind direction.

In one possible implementation, referring to FIG. 10, a gap H1 is provided between the heating plate 20 and the second wind deflector 50, where 0 < H1.ltoreq.4 mm. If the gap H1 is too large, the heat taken away by the wind flowing from the top of the second wind shielding rib 50 may be reduced, which affects the heat dissipation effect and may also cause an increase in the overall thickness of the cooking apparatus.

In one possible implementation, the gap H1 may be 1mm, 2mm, 3mm or 4mm to maximize the heat carried away by the wind flowing off the top of the second wind deflector rib 50.

In one possible implementation, referring to FIGS. 3 and 4, the length of the first step portion 41 is L1, where 3 mm.ltoreq.L1.ltoreq.8mm. If the length of the first step portion 41 is too small, the air inlet for concentrating the air into the air collecting chamber 114 becomes small, which is not beneficial to improving the air inlet amount, and the air speed may be fast, and unnecessary noise may easily occur. If the length of the first step 41 is too large, the wind force of the wind concentrated into the wind collecting chamber 114 is not concentrated enough, the wind speed of the wind blown into the wind collecting chamber 114 is relatively slow, and is relatively scattered, so that it is difficult to increase the wind force of the wind collecting region A1, and more wind cannot directly reach the position where the temperature rise of the heating plate 20 is highest, thereby affecting the heat dissipation effect. Therefore, the heat dissipation device can avoid noise and other problems while improving the heat dissipation effect by enabling the L1 to be more than or equal to 3mm and less than or equal to 8mm.

In one possible implementation, the length L1 of the first step 41 may be 3mm, 4mm, 5mm, 6mm, 7mm or 8mm.

In one possible implementation, referring to FIGS. 3 and 4, the notched bead 51 has a length L2, where 4mm < L2.ltoreq.8.5 mm.

In one possible embodiment, as shown in fig. 3 and 4, the projection of the notch rib 51 on the horizontal plane may be linear, circular arc, or arc segment.

Since the wind blown by the fan 30 moves along the tangential direction of the circle in which the fan blades rotate, if the length L2 of the notch rib 51 is too small, a large amount of wind entering beyond the notch rib 51 is blocked, and the amount of wind entering the wind collecting chamber 114 is suddenly reduced, the effect of radiating the heat from the wind collecting chamber 114 toward the bottom of the heating plate 20 is not significant, and the length L2 of the notch rib 51 cannot be too small. Conversely, if the length of the notch rib 51 is too large, the wind is relatively dispersed, the wind force entering the wind collecting chamber 114 is not concentrated enough, the wind force of the wind collecting region A1 in the wind collecting chamber 114 is difficult to increase, and a part of the wind blows to other places instead of the lower part of the heating plate 20, which is not beneficial to increasing the heat dissipation effect of the heating plate 20.

Referring to fig. 11 and 12, the lower cover 11 is provided with a side wind shielding rib 80, and the side wind shielding rib 80 is located at one side of the heating pan 20 in order to shield a large amount of wind and reflect the wind toward the one side back to the heating pan 20, so that the wind blown toward the panel 13 from above the heating pan 20 may take away a part of heat above the heating pan 20 and on the inner surface of the panel 13 to cool the heating pan 20.

In one possible embodiment, the first wind shielding rib 40, the second wind shielding rib 50, the third wind shielding rib 60, the guide rib 70, and the side wind shielding ribs 80 may be an integral structure integrally formed with the lower cover 11.

Referring to fig. 11, 13 and 14, the side wind shielding ribs 80 are spaced from the panel 13 by a certain distance, and a plurality of grooves 81 are formed in one end of the side wind shielding ribs 80 facing the panel 13 to reduce the rigidity of the side wind shielding ribs 80, so that the problem that the side wind shielding ribs 80 are excessively hard to top the broken panel 13 in the falling process of the cooking device can be effectively prevented.

Considering that most of the wind of the fan 30 will blow to the heating plate 20 first, most of the wind is reflected to the position of the heating plate 20 by the side wind shielding ribs 80 on the outer side of the heating plate 20, in this process, the wind leaks from the gaps between the side wind shielding ribs 80 and the panel 13, there is a loss of wind quantity, and in addition, some wind leaks from the edge of the panel 13 or moves along the edge of the panel 13, the wind force and the wind pressure of the wind are lost, so the wind force, the wind speed and the wind pressure of the wind reflected back by the side wind shielding ribs 80 are insufficient, and it is difficult to quickly transfer the heat of the heating plate 20. The utility model provides cooking equipment, because the space in the wind collecting cavity 114 at the lower side of the heating plate 20 is relatively large, most of wind blown into the wind collecting cavity 114 is reflected by the guiding of the wind shielding structure, so that the defects of heat radiation wind quantity and wind power on the upper surface of the heating plate 20 are overcome, the utilization rate of the wind is improved, and the heat radiation efficiency of the heating plate 20 is improved.

In one possible implementation, referring to fig. 11 and 16, a mounting hole 121 is formed in the upper cover 12, a panel 13 is disposed on the mounting hole 121, and the panel 13 is located on the upper side of the heating plate 20; in the thickness direction of the cooking apparatus, at least part of the projection of the blower 30 is located outside the projection area of the panel 13. With such a structure, the panel 13 does not completely cover the upper surface of the cooking apparatus, and the area of the panel 13 is small, which is advantageous in saving the material cost of the panel 13.

For waterproofing, a boss 123 may be provided at the edge of the mounting hole 121, the boss 123 protrudes from the surface of the upper cover 12 by a certain height, the boss 123 may be rounded, and the boss 123 is used to adhere the panel 13. To ensure that the magnetic moment is unchanged, the corresponding hotplate 20 also needs to be raised to a certain height.

It is easy to understand that, because the heating plate 20 is located the upside of collection wind chamber 114, the space of heating plate 20 downside grow, the wind that blows to heating plate 20 bottom can't directly blow to heating plate 20, can only take away the heat that heating plate 20 radiated down, in order to better utilize the wind that blows to heating plate 20 bottom, improve the radiating efficiency of heating plate 20, be equipped with the structure of keeping out the wind at collection wind chamber 114's edge circumference, the structure of keeping out the wind can be with the gathering zone of wind guide, also can be with the wind guide upward blow to heating plate 20.

In one possible implementation, the mounting holes 121 may be circular holes and the panel 13 a circular panel, and the panel 13 may be a porcelain plate, such as a borosilicate glass panel.

The heating plate 20 is located under the panel 13, for heating the cookware placed on the panel 13, the bottom of the lower cover 11 is connected with a plurality of supporting legs 116, for example, four supporting legs 116 may be connected to four corner positions, and the four supporting legs 116 are respectively connected to four corner positions, so that the placement stability of the cooking device can be improved.

The lamp plate 93 and the power panel 92 are further arranged in the accommodating cavity, part of the lamp plate 93 is located on the upper side of the fan 30, the heating disc 20 and the lamp plate 93 are electrically connected with the power panel 92, and the fan 30 is used for accelerating the exchange speed of air in the accommodating cavity and outside air and plays a role in heat dissipation and cooling.

The upper cover 12 is provided with a function display panel 122, and operation keys such as power on, power off, temperature adjustment and the like can be displayed through the function display panel 122, and the function display panel 122 corresponds to the position of the lamp panel 93.

When the cooking device is an induction cooker, the heating plate 20 is a coil plate, and the high-frequency alternating electromagnetic field generated by the coil plate generates eddy current in the cookware so as to realize electromagnetic heating.

The magnetic moment of the coil disk is determined so that the height of the first step 41 can be determined according to the magnitude of the magnetic moment of the coil disk. As shown in fig. 10 and 11, in the case of determining the coil disk, the magnetic moment of the coil disk is known, the height of the coil disk is determined, a gap H1 is required between the top surface of the second wind shielding rib 50 and the bottom surface of the coil disk, 0 < H1 is less than or equal to 4mm, the gap H1 is not easily excessively large, and then the top surface height H of the second wind shielding rib 50 is the height of the bottom surface of the coil disk minus the gap H1.

After the height H of the top surface of the second wind shielding rib 50 is determined, as shown in fig. 8 and 15, since the height of the second wind shielding rib 50 is required to be greater than the height of the first step portion 41, the difference in height between the second wind shielding rib 50 and the first step portion 41 is H2, wherein 5mm < H2 < 12mm, so that the height of the top surface of the first step portion 41 can be determined, and the height of the top surface of the first step portion 41 is the height H of the top surface of the second wind shielding rib 50 minus H2.

It is easy to understand that the height of the top surface of the first step portion 41 cannot be too low, otherwise a larger height difference is formed with the second wind shielding rib 50, so that wind blowing under the coil panel climbs a larger height, and more wind is difficult to go out from a gap between the coil panel and the second wind shielding rib 50 or a gap of the coil panel, so that more wind is accumulated under the coil panel, and heat dissipation of the coil panel is affected.

According to the embodiment, by adding improvement, the air quantity moving in the air collecting cavity 114 at the lower side of the heating disc 20 can be effectively increased, the air speed is increased, more air can be blown to the disc bottom position of the heating disc 20 corresponding to the highest temperature rising area of the heating disc 20, the overall temperature rising of the heating disc 20 is effectively reduced, and the utilization rate of the air and the heat dissipation efficiency of the heating disc 20 are improved.
