A first intake vent 300 and a second intake vent 400 are disposed in the first area 150, at least a portion of the first intake vent 300 is disposed on the first sidewall 110, the second sidewall 120 includes a first section 121 adjacent to the first sidewall 110 and a second section 122 away from the first sidewall 110, the first section 121 is connected to the second section 122, and at least a portion of the second intake vent 400 is disposed on the second section 122 of the second sidewall 120.

When the first air inlet 300 of this embodiment is specifically arranged, it may be arranged on the first side wall 110, so as to avoid the situation that the accumulated water on the tabletop is sucked into the bottom case 100 when the induction cooker works, prolong the service life of the electronic devices in the induction cooker, and avoid the occurrence of unsafe accidents. Of course, the first intake vent 300 may be disposed on the bottom wall adjacent to the first sidewall 100.

In some examples, the first air inlet 300 may be further disposed on the first section 121 of the second sidewall 120 close to the first sidewall 110 to increase the amount of cool air entering the first area 150 of the accommodating cavity, so as to increase the amount of cool air entering the second area 160, and improve the heat dissipation efficiency of the coil panel 700 and the power supply board 800.

Similarly, when the second air inlet 400 is specifically arranged, it may be only arranged at the second section 122 of the second side wall 120, so as to avoid the situation that the accumulated water on the table top is sucked into the bottom case 100 when the induction cooker works, prolong the service life of the electronic devices in the induction cooker, and avoid unsafe accidents. Certainly, the second air inlet 400 may also be disposed on the bottom wall of the second section 122 close to the second side wall 120, so as to increase the amount of cold air entering the first area of the accommodating cavity, thereby increasing the amount of cold air entering the second area, and improving the heat dissipation efficiency of the coil panel 700 and the power board 800.

Wherein, this first lateral wall 110 can be towards user's preceding lateral wall, like this, sets up and is provided with first air intake 300 on first lateral wall 110 towards the user, and first air intake 300 can be observed at any time to when first air intake 300 takes place to block up, the user can in time clear up, with the normal heat dissipation of assurance electromagnetism stove.

In practical application, screw posts 155 are disposed at corners of four sidewalls of the bottom case 100, and the panel of the induction cooker is fixed to the bottom case 100 through the screw posts 155.

In this embodiment, when the first section of the second sidewall 120 close to the first sidewall 110 and the first sidewall 110 are both provided with the first air inlet 300, the screw column 155 can reinforce the sidewall of the bottom case 100 at the position, so as to prevent the sidewall from deforming, and prolong the service life of the induction cooker.

The air inlet of the present embodiment includes a first air inlet 650 and a second air inlet 660, a first air storage area 151 is formed between the first air inlet 650 and the first air inlet 300, the first section 121 of the second sidewall 120 is located in the first air storage area 151, and a second air storage area 152 is formed between the second air inlet 660 and the second air inlet 400. A communication channel 153 is further arranged between the first wind storage area 151 and the second wind storage area 152, and the first wind storage area 151 is communicated with the second wind storage area 152 through the communication channel 153.

Referring to fig. 1 and 3, the first air storage zone 151 is specifically an area formed between the first air inlet 650 and the first air inlet 300 of the first sidewall 110 and the first section 121 of the second sidewall 120, and the second air storage zone 152 is specifically an area formed between the second air inlet 600 and the second air inlet 400 of the second sidewall 120. The communication channel 153 is specifically a junction area of the first wind storage area 151 and the second wind storage area 152, as shown by a dashed line frame in fig. 1. It is understood that the communication passage 152 is an area sandwiched between the inner bottom wall and the panel at the boundary of the first and second wind storage areas 151 and 152. In some examples, the communication passage 152 may also be a through hole provided on a baffle at the intersection of the first and second wind storage regions 151 and 152, through which communication between the first and second wind storage regions 151 and 152 is achieved.

In this embodiment, two ends of the wind-blocking rib 600 may be respectively connected to the fourth sidewall 140 and the second sidewall 120, as shown in fig. 1 and fig. 3, so that the wind-blocking rib 600, a part of the second sidewall 120, the first sidewall 110, and a part of the fourth sidewall 140 enclose a first area 150, and the other area of the accommodating cavity is the second area 160. In some examples, both ends of the wind shielding rib 600 may be further connected to the fourth sidewall 140 and the third sidewall 130, respectively, so that the wind shielding rib 600, a portion of the third sidewall 130, a portion of the second sidewall 120, the first sidewall 110, and a portion of the fourth sidewall 140 jointly enclose the first area 150.

In this embodiment, the display panel 810 is disposed in the first region 150, and other components such as the coil panel 700 and the power board 820 are disposed in the second region 160, so that the display panel 810 and the other components such as the coil panel 700 are separated by the wind shielding rib 600, and the display panel 810 is not affected by the high temperature of the other components, particularly the coil panel 700 and the power board 820 which generate a large amount of heat, thereby prolonging the service life of the display panel 810.

The air inlet of the present embodiment may be disposed at a corner of the wind shielding rib 600, and specifically, the first air inlet 650 may be disposed opposite to the first sidewall 110 to reduce a distance between the first air inlet 300 and the first air inlet 650, so that cold air entering the first air storage region 151 through the first air inlet 300 can directly enter the second region 160 through the first air inlet 650. Similarly, the second air inlet 660 may be disposed opposite to the second sidewall 120 to reduce a distance between the second air inlet 400 and the second air outlet 660, so that the cool air entering the second air storage area 152 through the second air inlet 400 can directly enter the second area 160 through the second air inlet 660.

When the induction cooker of this embodiment specifically radiates heat, external cold air enters the first air storage region 151 through the first air inlet 300, wherein a portion of the cold air in the first air storage region 151 enters the second region 160 through the first air inlet 650, and another portion of the cold air enters the second air storage region 152 through the communication channel 153, and then enters the second region 160 through the second air inlet 660. Meanwhile, the outside cold air also enters the second air storage area 152 through the second air inlet 400, wherein a part of the cold air in the second air storage area 152 enters the second area 160 through the second air inlet 660, and the other part of the cold air enters the first air storage area 151 through the communication channel 153, and then enters the second area 160 through the first air inlet 660.

A portion of the cool air in the second region 160 enters the fan cavity 210 of the heat dissipation fan 200, and after being accelerated, the cool air is blown to the coil panel 700 and the power board 820 from the air outlet surface of the fan cavity 210, so as to dissipate heat of the coil panel 700 and the power board 820. Another portion of the cool air in the second area 160 directly flows through the coil panel 700 and the power board 820, and dissipates heat from the coil panel 700 and the power board 820. The fan cavity 210 of the heat dissipation fan 200 is specifically a receiving area formed between the outer shell of the heat dissipation fan 200 and the inner bottom wall of the bottom case 100.

In this embodiment, the first air inlet 300 communicated with the first air storage area 151 is disposed on the first side wall 110, the second air inlet 400 communicated with the second air storage area 152 is disposed on the second section 122 of the second side wall 120, so that the number of the air inlets is increased, the amount of cold air entering the accommodating cavity of the induction cooker is increased, external cooling air enters the accommodating cavity of the induction cooker from the air inlets at different positions, heat is dissipated from heating elements such as the coil panel 700, the power panel 820 and the display panel 810, and the heat dissipation efficiency of the induction cooker is improved.

In practical applications, the first air inlet 300 and the second air inlet 400 may be blocked by external dust or oil. When the air inlet at any one of the first air inlet 300 and the second air inlet 400 is blocked, the external cooling air can enter the first air storage area 151 and the second air storage area 152 through the unblocked air inlet to dissipate heat of the display panel 810, and can enter the second area 160 to dissipate heat of the coil panel 700 and the power panel 820, thereby ensuring normal heat dissipation operation of the induction cooker.

For example, when the first air inlet 300 is blocked, the external cooling air enters the second air storage area 152 through the second air inlet 400 disposed on the second section 122 of the second sidewall 120, a part of the cooling air in the second air storage area 152 enters the second area 160 through the second air inlet 660, and cools the heating elements such as the coil panel 700 and the power board 820, and another part of the cooling air in the second air storage area 152 enters the first air storage area 151 through the communicating channel 153, and then enters the second area 160 through the first air inlet 650, and cools the heating elements such as the coil panel 700, so that the normal heat dissipation of the induction cooker is effectively ensured. It can be seen that when the first air inlet 300 is blocked, the external cold air can enter the first area 150 through the second air inlet 400 to dissipate heat from the display panel 810, and then enter the second area 160 through the air inlet to dissipate heat from the coil panel 700 and the power board 820, thereby ensuring normal cooling of the induction cooker.

Similarly, when the second air inlet 400 is blocked, the external cooling air may enter the first air storage region 151 through the first air inlet 300, a part of the cooling air located in the first air storage region 151 directly enters the second region 160 through the first air inlet 650, and the other part of the cooling air enters the second air storage region 152 through the communicating channel 153, and then enters the second region 160 through the second air inlet 669, so as to dissipate heat of the coil panel 700 and the power board 820. It can be seen that when the second air inlet 400 is blocked, the external cold air can enter the first region 150 through the first air inlet 300 to dissipate heat from the display panel 810, and then enter the second region 160 through the air inlet to dissipate heat from the coil panel 700 and the power board 820, thereby ensuring normal cooling of the induction cooker.

Based on the above, the first air inlet 300 and the second air inlet 400 are arranged, so that the problem that the normal heat dissipation of the induction cooker is affected due to the fact that the external cold air cannot enter the accommodating cavity due to the blockage of the air inlet arranged on one side wall of the conventional induction cooker is effectively solved.

In addition, in the present embodiment, the first wind storage area 151 and the second wind storage area 152 are communicated through the communication channel 153, and compared with the first wind storage area 151 and the second wind storage area 152 which are isolated from each other, a vortex phenomenon caused by collision between the cooling wind entering the bottom case 100 and wind deflectors is effectively avoided, that is, a dead angle area is generated before the cold wind enters the second area 160, so that the cold wind cannot smoothly enter the second area 160, or even a part of the cooling wind flows back to the first wind inlet 300 or the second wind inlet 400 and is discharged outside, so that a loss of a part of the cooling wind is avoided, a difference between the amount of the wind entering the bottom case 100 through the first wind inlet 300 and the second wind inlet 400 and the amount of the wind entering the second area 160 is reduced, so that the cooling wind of the first wind storage area 151 and the second wind storage area 152 can enter the second area 160 to a greater extent, thereby increasing the cooling wind amount flowing through the heating elements such as the coil panel 700, thereby improving the heat dissipation efficiency of the induction cooker.

Referring to fig. 2, in the present embodiment, the first air storage area 151 and the second area 160 are communicated through the first air inlet 650, and on the first hand, a path of cooling air entering the second area 160 of the bottom case 100 from the first air inlet 300 is shortened, so that the cooling air entering the first air storage area 151 from the first air inlet 300 can directly enter the fan cavity 210 of the heat dissipation fan 200 through the first air inlet 650 after passing through the first air storage area 151, and the air consumption of the cooling air in the first air storage area 151 is reduced, thereby ensuring the cooling air volume entering the second area 160, and improving the heat dissipation efficiency of other heating elements, and on the other hand, the cooling air in the second air storage area 152 can also flow to the first air storage area 151 and enter the second area 160 through the first air inlet 650, thereby ensuring the heat dissipation efficiency of other heating elements.

Similarly, the second air storage area 152 is communicated with the second area 160 through the second air inlet 660, so that a path of cooling air entering the second area 160 from the second air inlet 400 is shortened, air consumption of the cooling air entering the second area 160 from the second air storage area 152 is reduced, meanwhile, a part of air flow in the first air storage area 151 can enter the second air storage area 152 through the communicating channel 153 and enters the second area 160 through the second air inlet 660, and therefore the cooling air entering the accommodating cavity through the first air inlet 300 can also enter the second area 160, and effective heat dissipation is performed on other heating elements.

In addition, when any one of the first air inlet 650 and the second air inlet 660 is blocked, the cooling air entering the first air storage region 151 and the second air storage region 152 through the first air inlet 300 and the second air inlet 400 can enter the second region 160 through the unblocked air inlet, thereby ensuring effective heat dissipation of other heating elements inside the bottom case 100.

The first air inlet 650 and the second air inlet 660 can be arranged in a penetrating manner, in other words, the first air inlet 650 and the second air inlet 660 together form a communicated air inlet, so that cold air in the first air storage area 151 and the second air storage area 152 can more smoothly enter the second area 160 through the air inlet with the larger caliber, thereby reducing air volume loss on a path entering the second area 160, and further improving heat dissipation efficiency of other heating elements.

In some examples, the first air inlet 650 and the second air inlet 660 may be spaced apart from each other, so that when any one of the first air inlet 650 and the second air inlet 660 is blocked, the cooling air entering the first air storage region 151 and the second air storage region 152 through the first air inlet 300 and the second air inlet 400 can enter the second region 160 through the unblocked air inlet, so as to effectively dissipate heat of other heat generating components inside the bottom case 100.

Referring to fig. 4 to 7, in practical application, the heat dissipation fan 200 includes a fan bracket 220, a rotating portion 230, and a fan blade 240 connected to the rotating portion 230. The rotating portion 230 is movably fixed on the fan bracket 220, so that the rotating portion 230 can rotate on the fan bracket 220 under the driving of the motor, thereby driving the fan blades 240 to rotate, the fan bracket 220 is arranged opposite to the inner bottom wall of the bottom case 100, and when the heat dissipation fan 200 is fixed, the fan bracket 220 can be fixed on the bottom case 100 by fixing the heat dissipation fan 200, so as to ensure the stability of the heat dissipation fan 200 in the bottom case 100. It is understood that the rotating portion 230 may be a rotating shaft fixed in a mounting hole formed in the fan bracket 220 through a bearing.

The cooling fan 200 of the present embodiment is specifically an axial flow fan. When the heat dissipation fan 200 is installed in the bottom case 100, a side of the fan blade 240 of the heat dissipation fan 200 facing the panel is used as an air outlet side, and a side of the fan blade 240 of the heat dissipation fan 200 facing the inner bottom wall of the bottom case 100 is used as an air inlet side.

When the heat dissipation fan 200 works, the air in the second area 160 enters the fan cavity 210 of the heat dissipation fan 200 from the air inlet side of the heat dissipation fan 200, and then is sent to the air outlet side of the heat dissipation fan 200 under the high-speed rotation of the fan blades 240, and the high-speed spiral air flow at the air outlet side needs to turn to the horizontal direction, so as to dissipate the heat of the coil panel 700 and the power panel 820 in the second area 160.

In order to reduce the resistance of the high-speed spiral airflow at the air outlet side to the horizontal direction, the fan bracket 220 of the cooling fan 200 is arranged at the air inlet side of the cooling fan 200 in the embodiment, so as to reduce the resistance of the high-speed spiral airflow at the air outlet side of the cooling fan after the fan blades of the cooling fan accelerate to flow horizontally, thereby reducing the resistance at the air outlet side of the cooling fan, further increasing the cold airflow flowing to heating components such as a coil panel and a power panel, and improving the cooling efficiency of the induction cooker.

Specifically, in the present embodiment, since the space between the upper surface of the heat dissipation fan 200 and the panel of the induction cooker is limited, the fan bracket 220 is located at the lower side of the fan blade 240. Thus, during operation, the cold air in the second region 160 enters the fan cavity 210 from the bottom of the fan bracket 220 at the lower side of the heat dissipation fan 200 and is delivered to the upper side of the fan blade 240 under the high-speed rotation of the fan blade 240, and the high-speed spiral air flow at the upper surface of the fan blade 240 is blown to the side from the space between the panel and the fan blade 240 without being obstructed by the fan bracket 220, so that the wind resistance that the high-speed spiral air flow at the upper side of the heat dissipation fan 200 turns to flow in the horizontal direction is reduced, the cold air volume blown out by the heat dissipation fan 200 is increased, and the heat dissipation efficiency of the coil panel 700 and the power supply board 820 is improved.

Since the fan bracket 200 is disposed under the fan blade 240, it occupies a space between the lower surface of the fan blade 240 and the inner bottom wall of the bottom chassis 100. Therefore, in order to avoid the influence on the air intake of the heat dissipation fan 200, in this embodiment, the distance between the bottom surface of the fan bracket 220 and the inner bottom wall of the bottom casing 100 is greater than or equal to 3mm, so as to avoid that the distance between the fan bracket 220 arranged at the bottom of the fan blade 240 and the inner bottom wall of the bottom casing 100 is too small to prevent cold air from entering the fan cavity 210 of the heat dissipation fan 200 through the bottom of the heat dissipation fan 200, that is, the air resistance entering the fan cavity 210 from the bottom air intake surface of the heat dissipation fan 200 is reduced, the air consumption on the path entering the fan cavity 210 of the heat dissipation fan 200 is reduced, and the amount of cold air entering the heat dissipation fan 200 is increased.

It is understood that the present embodiment is described with the upper side of the heat dissipation fan 200 being the air outlet side and the lower side being the air inlet side. In other examples, when the upper side of the heat dissipation fan 200 is the air inlet side and the lower side of the heat dissipation fan 200 is the air outlet side, in order to reduce the resistance of the high-speed air flow when the heat dissipation fan 200 is blown out, in the present embodiment, the fan bracket 220 of the heat dissipation fan 200 is disposed on the upper side of the fan blade 240, so as to increase the size of the space between the lower side of the heat dissipation fan 200, that is, the air outlet surface, and the inner bottom wall of the bottom chassis 100, thereby increasing the amount of air blown from the lower air outlet surface to the side by the heat dissipation fan 200, and further improving the heat dissipation efficiency of the coil panel 700 and the power board 820. In order to prevent the fan bracket 220 disposed above the fan blade 240 from affecting the air intake of the heat dissipation fan 200, the distance between the top surface of the fan bracket 220 and the panel may be greater than or equal to 3mm, so as to prevent the gap between the fan bracket 220 disposed on the upper side of the fan blade 240 and the panel from being too small to prevent the external air flow from entering the fan cavity 210 of the heat dissipation fan 200 from the air intake side between the fan bracket 220 and the panel, that is, to reduce the resistance of the external air flow entering the fan cavity 210 from the air intake side of the heat dissipation fan 200, thereby increasing the air volume entering the fan cavity 210 of the heat dissipation fan 200.

Referring to fig. 1, in the present embodiment, the heat dissipation fan 200 is disposed close to the air inlet, so that the cooling air entering the second area 160 through the air inlet can enter the fan cavity 210 of the heat dissipation fan 200 to a greater extent, that is, the cooling air entering the heat dissipation fan 200 is increased, thereby increasing the cooling air with high wind speed blowing to the heating elements such as the coil panel 700 and the power board 820, and further effectively taking away the heat on the coil panel 700 and the power board 820, so as to improve the heat dissipation efficiency of the electromagnetic oven.

Referring to fig. 4 and 5, when the blower bracket 220 and the bottom case 100 of the present embodiment are assembled, the first connecting portions 221 may be disposed at two ends of the blower bracket 220, and the second connecting portions may be disposed on the inner bottom wall of the bottom case 100, so that the blower bracket 220 and the bottom case 100 are connected by the mutual matching of the first connecting portions 221 and the second connecting portions.

In some examples, the first connection portion 221 may be a screw hole opened at both ends of the blower fan bracket 220, while the second connection portion is a screw hole opened on an inner bottom wall of the bottom case 100. When the fixing is performed, one end of a fastener such as a screw, a bolt, or a rivet sequentially passes through the screw hole of the blower bracket 220 and the screw hole of the inner bottom wall of the bottom chassis 100, so that the blower bracket 220 is fixed to the inner bottom wall of the bottom chassis 100, thereby realizing the assembly of the heat dissipation blower 200. In other examples, the first connection portion 221 may also be a protrusion portion disposed on the blower bracket 200 and extending toward the inner bottom wall of the bottom case 100, and the second connection portion 221 is a slot matched with the protrusion portion. The protrusion on the blower bracket 220 is clamped in the groove of the bottom case 100, so that the blower bracket 220 is stably connected with the bottom case 100.

When the fan support 220 is fixed, two ends of the fan support 220 may extend out of the outer edge of the fan blade 240 and be staggered with the air inlet of the wind shielding rib 600, so as to prevent the connection structure between the fan support 220 and the bottom case 100 from blocking cold air from entering the fan cavity 210 of the heat dissipation fan 200 from the air inlet of the wind shielding rib 600, so that the cold air in the first area 150 can smoothly enter the fan cavity 210 of the heat dissipation fan 200, and the loss of the cold air on the path entering the fan cavity 210 of the heat dissipation fan 200 is reduced.

In a specific implementation, the projection of the heat dissipation fan 200 on the second sidewall 120 of the embodiment is located at the second section 122 of the second sidewall 120, in other words, the fan cavity 210 of the heat dissipation fan 200 is arranged opposite to the second section 122 of the second sidewall 120, so that the cooling air entering the second air storage area 152 through the second air inlet 400 can directly enter the fan cavity 210 of the heat dissipation fan 200, and compared with the case that the heat dissipation fan 200 is arranged at a position close to the first sidewall 110, on one hand, the spatial size of the first air storage area 151 is increased, so that a heating element is conveniently arranged in the first air storage area 151, and the heating element is cooled by the cooling air in the first air storage area 151; on the other hand, the sizes of the part of the first air storage area 151 and the communication channel 153 of the first section 121 of the second side wall 120 are also increased, so that the cold air of the part of the first air storage area 151 near the first section 121 of the second side wall 120 can smoothly enter the second air storage area 152 and the fan cavity 210 of the heat dissipation fan 200 through the communication channel 153, that is, the loss of the cooling air near the connection between the first side wall 110 and the second side wall 120 is reduced, and the cooling air volume entering the fan cavity 210 of the heat dissipation fan 200 is increased.

In this embodiment, the heat dissipation fan 200 may further include a housing disposed at the periphery of the fan blade 240, a vent (not shown in the figure) is disposed on the housing, and the vent is communicated with the air inlet, so that cold air entering the second region 160 through the air inlet can directly enter the fan cavity 210 of the heat dissipation fan 200 through the vent, on one hand, the cooling air volume entering the fan cavity 210 of the heat dissipation fan 200 is ensured, on the other hand, the housing of the heat dissipation fan 200 is also disposed to further prevent the cooling air in the heat dissipation fan 200 from entering the first air storage region 151 or the second air storage region 152, and the cooling air volume blown out from the air outlet surface of the heat dissipation fan 200 is increased.

It is understood that the ventilation opening may be an opening opened on the outer case, and of course, in some examples, the ventilation opening may also be a gap formed between the bottom end of the outer case and the inner bottom wall of the bottom case 100. The present embodiment does not limit the specific arrangement of the vents.

In this embodiment, when the lower surface of the heat dissipation fan 200 is an air inlet surface, the upper surface of the heat dissipation fan 200 is an air outlet surface. The top of the first air inlet 650 and/or the second air inlet 660 is flush with or lower than the air inlet surface of the heat dissipation fan 200, so that the cooling air in the first air storage region 151 and/or the second air storage region 152 can smoothly enter the air inlet surface of the heat dissipation fan 200, then rotate to the top air outlet surface under the action of the fan blades, and then be discharged to the heat dissipation region. The heat dissipation area 190 is specifically an area where the coil panel 700, the power board 820, and the like are disposed in the second area 160.

In addition, the above arrangement prevents the cooling air in the fan cavity 210 of the heat dissipation fan 200 higher than the air inlet surface from flowing back to the first air storage region 151 and/or the second air storage region 152 from the first air inlet 650 and/or the second air inlet 660, so as to ensure the air outlet amount of the air outlet surface of the heat dissipation fan 200, thereby improving the air amount flowing through other heating elements such as the coil panel 700 and the like, and ensuring the heat dissipation efficiency.

Referring to fig. 1 to 3, when specifically arranged, the wind-blocking rib 600 of the present embodiment includes a first wind-blocking rib 610 and a second wind-blocking rib 620 that surround the periphery of the fan cavity 210 of the heat dissipation fan 200. A first end of the first wind blocking rib 610 is connected with a first end of the second wind blocking rib 620, and a first wind inlet 650 is formed between the first wind blocking rib 610 and the inner bottom wall of the bottom case 100; a second air inlet 660 is formed between the second air blocking rib 620 and the inner bottom wall of the bottom chassis 100.

Taking the first wind blocking rib 610 as an example, a part of the bottom end of the first wind blocking rib 610 in the extending direction may be fixed on the inner bottom wall of the bottom case 100, and a gap is formed between the part of the bottom end and the inner bottom wall of the bottom case 100, and the gap is used as the first wind inlet 650 of the embodiment. Of course, in some examples, a gap is formed between all bottom ends of the first wind blocking rib 610 and the inner bottom wall of the bottom case 100, and the gap is used as the first wind inlet 650 of the present embodiment.

This embodiment sets up first wind blocking muscle 610 between first wind storage area 151 and cooling fan 200's fan chamber 210 to the lateral part towards first wind storage area 151 of cooling fan 200's fan chamber 210 separates, thereby avoids getting into the air current in cooling fan 200's fan chamber 210 and spills from the side, and causes the influence to other heat element's radiating efficiency.

The second wind-blocking rib 620 has a similar structure and technical effect to the first wind-blocking rib 610, and is not described herein again.

In addition, in the embodiment, the first air inlet 650 and the second air inlet 660 are disposed on the wind blocking rib 600, so as to reasonably utilize the components in the bottom case 100, thereby reducing the component arrangement of the induction cooker and improving the assembly efficiency of the induction cooker.

The wind blocking rib 600 of this embodiment can be integrated with the bottom case 100 when specifically being fixed, so not only the structure of the induction cooker is simplified, but also the connection strength between the wind blocking rib 600 and the bottom case 100 is improved, so that the wind blocking rib 600 is more firmly fixed on the bottom case 100, thereby ensuring the blocking effect of the wind blocking rib 600 on the lateral air flow of the heat dissipation fan 200, and simultaneously also ensuring the stability of the first air inlet 650 and the second air inlet 660 formed between the bottom ends of the first wind blocking rib 610 and the second wind blocking rib 620 and the inner bottom wall of the bottom case 100 respectively.

In some examples, the wind shielding rib 600 is also provided separately from the bottom case 100, and the wind shielding rib 600 is fixed to the bottom case 100. For example, when a portion of the wind shielding rib 600 contacts with the inner bottom wall of the bottom case 100, a slot may be disposed on the bottom case 100, and a portion of the wind shielding rib 600 in the length direction may be clamped in the slot of the bottom case 100, so as to fix the wind shielding rib 600 to the bottom case 100, and at the same time, it is ensured that an air inlet is formed between the bottom end of the portion of the wind shielding rib 600 in the length direction and the inner bottom wall of the bottom case 100. Of course, a part of the bottom end of the wind shielding rib 600 may be adhered to the inner bottom wall of the bottom case 100, so that the wind shielding rib 600 is stably fixed to the bottom case 100. In other examples, the windshield rib 600 and the bottom case 100 may be connected in other manners, and the present embodiment does not limit the connection manner between the windshield rib 600 and the bottom case 100.

When there is a gap between all bottom ends of the wind-shielding rib 600 in the extending direction and the inner bottom wall of the bottom chassis 100, the side wall of the wind-shielding rib 600 and the inner wall of the bottom chassis 100 may be connected by a fixing member such as a connecting rod. When the fixing is carried out, the fixing of the wind shielding rib 600 can be realized by connecting the two ends of the connecting rod with the side wall of the wind shielding rib 600 and the inner wall of the bottom case 100 respectively.

In addition, the first wind-blocking rib 610 and the second wind-blocking rib 620 of the wind-blocking rib 600 may also be connected to the heat dissipation fan 200. For example, the first wind blocking rib 610 and the second wind blocking rib 620 may be connected to a bracket of the heat dissipation fan 200. Wherein, this first wind-break muscle 610 and second wind-break muscle 620 can the snap-on cooling fan 200's support, also can guarantee the steadiness of this first wind-break muscle 610 and second wind-break muscle 620 through mounting such as fix with screw on this support, guarantee that this first wind-break muscle 610 and second wind-break muscle 620 effectively stop the air current that cooling fan 200's lateral part spilt.

Referring to fig. 2, the bottom case 100 of the present embodiment further includes support ribs 670; the support rib 670 is located between the wind shielding rib 600 and the inner bottom wall of the bottom chassis 100, and is used to support the wind shielding rib 600, so as to ensure the stability of the wind shielding rib 600 in the vertical direction. Specifically, the support rib 670 is disposed near the first air inlet 650 and/or the second air inlet 660 to ensure stability of the second air inlet 660 formed between the bottom end of the first air inlet 650 and/or the second air blocking rib 620 formed between the bottom end of the first air blocking rib 610 of the wind blocking rib 600 and the inner bottom wall of the bottom chassis 100.

For example, the support rib 670 may be disposed at a side of the first air inlet 650 far from the second air inlet 660 to further ensure stability of the first air inlet 650 formed between the bottom end of the first wind blocking rib 610 and the inner bottom wall of the bottom chassis 100, thereby ensuring that the air flow in the first air storage region 151 can enter the fan cavity 210 of the heat dissipation fan 200 through the first air inlet 650.

Or, the support rib 670 is disposed on a side of the second air inlet 660 far from the first air inlet 650, so as to further ensure stability of the second air inlet 660 formed between the bottom end of the second air blocking rib 620 and the inner bottom wall of the bottom chassis 100, thereby ensuring that the air flow in the second air storage area 152 can enter the fan cavity 210 of the heat dissipation fan 200 through the second air inlet 660.

In some examples, the support rib 670 is disposed at a connection portion between the first air inlet 650 and the second air inlet 660, as shown in fig. 3, so that the support rib 670 is disposed at a position to achieve stability of the first air inlet 650 and the second air inlet 660, that is, on the basis of ensuring stability of the first air inlet 650 and the second air inlet 660, thereby simplifying structural arrangement in the bottom case 100 and improving assembly efficiency of the induction cooker.

In this embodiment, the distance between the bottom ends of the first wind-blocking ribs 610 and/or the second wind-blocking ribs 620 and the inner bottom wall of the bottom case 100 is 3mm to 30mm, and the included angle between the bottom ends of the first wind-blocking ribs 610 and/or the second wind-blocking ribs 620 and the inner bottom wall of the bottom case 100 is-15 ° to 15 °.

The first wind-shielding rib 610 will be specifically described below as an example.

Through setting up the interval between the bottom with first wind-blocking muscle 610 and the interior diapire of drain pan 100 in above-mentioned within range, not only make the air current that is located in first wind district 151 can only get into heat dissipation fan 200's fan chamber 210 through this first income wind gap 650 to a great extent, but also avoided the inside air current of heat dissipation fan 200 to flow backward to first wind district 151 from this first income wind gap 650, thereby further ensured the amount of wind in heat dissipation fan 200, thereby guarantee the amount of wind of other heating elements of flowing through, ensure the radiating efficiency of electromagnetism stove.

Referring to fig. 2, an included angle between the bottom end of the first wind blocking rib 610 and the inner bottom wall of the bottom chassis 100 may be denoted as θ, and in this embodiment, the included angle θ is set between-15 ° and 15 °. It can be understood that, when the included angle θ is greater than 0 °, the bottom end of the first wind blocking rib 610 is inclined upward; when the included angle θ is smaller than 0 °, the bottom end of the first wind-shielding rib 610 is inclined downward. Therefore, the angle of the upward inclination of the bottom end of the first wind-shielding rib 610 of the present embodiment is set to be not more than 15 °, and the angle of the downward inclination of the bottom end of the first wind-shielding rib 610 is set to be not more than 15 °.

Specifically, because the distance between the inner bottom wall of the bottom case 100 and the panel is limited, thereby limiting the maximum thickness of the first wind blocking rib 610, the present embodiment sets the angle of the upward inclination of the bottom end of the first wind blocking rib 610 to be not more than 15 °, effectively avoiding the condition that the angle of the upward inclination of the bottom end of the first wind blocking rib 610 is too large and the thickness of one portion of the first wind blocking rib 610 is too small, thereby ensuring the mechanical strength of the first wind blocking rib 610, and further improving the stability of the first air inlet 650, and simultaneously ensuring the effective blocking of the wind inside the heat dissipation fan 200. In addition, the angle of the downward inclination of the bottom end of the first wind blocking rib 610 is set to be not more than 15 °, the situation that the distance between the bottom end of the first wind blocking rib 610 and the inner bottom wall of the bottom case 100 is too small to cause a part of the first wind blocking rib 610 to block the cooling wind is avoided, namely, the situation that the cooling wind is collided with the first wind blocking rib 610 when entering the fan cavity 210 of the heat dissipation fan 200 through the first wind inlet 650 and the cooling wind is lost is effectively avoided, so that the cooling wind in the first wind storage area 151 can smoothly enter the fan cavity 210 of the heat dissipation fan 200 from the first wind inlet 650.

Wherein, the width of the first wind-blocking rib 610 and/or the second wind-blocking rib 620 in the vertical direction is 3mm to 27 mm; the length of the first wind blocking rib 610 and/or the second wind blocking rib 620 in the horizontal direction is 20mm to 110 mm.

By setting the length and width of the first wind-shielding rib 610 and/or the second wind-shielding rib 620 within the above range, effective isolation of the heat dissipation fan 200 is ensured, the mechanical strength of the wind-shielding rib 600 is ensured, and the wind-shielding rib 600 is prevented from being deformed or even broken due to impact of airflow.

Simultaneously, through keeping off the width setting of first wind muscle 610 and/or second wind muscle 620 on vertical direction in above-mentioned within range, on the basis of guaranteeing the height in the certain extent in the income wind gap that forms between the bottom of this wind muscle and the interior diapire of drain pan 100, the width that has prevented the muscle of keeping off the wind is too big and make the electromagnetism stove in the transportation top and the panel of this wind muscle bump, cause the damage to the muscle of keeping off the wind or even the panel, thereby guaranteed the intact of electromagnetism stove in the transportation.

It is understood that, in a specific arrangement, widths of the first and second wind blocking ribs 610 and 620 in a vertical direction may be adjusted according to a distance between an inner bottom wall of the bottom case 100 and an inner surface of the panel.

In addition, as for the second wind blocking rib 620, the second wind blocking rib 620 may be disposed around a portion of the side wall of the heat dissipation fan 200 facing the second side wall 120, that is, the second end of the second wind blocking rib 620 is located on the outer side wall of the heat dissipation fan 200, as shown in fig. 1 to 3.

In some examples, the second end of the second wind blocking rib 620 extends out of a side of the heat dissipation fan 200 facing away from the first sidewall 110, that is, a portion of the second wind blocking rib 620 extends out of a region between the heat dissipation fan 200 and the second sidewall 120, as shown in fig. 4. For example, the second end of the second wind blocking rib 620 extends to one half, two thirds (as shown in fig. 4) of the second sidewall 120, or the second end of the second wind blocking rib 620 extends to a portion of the second sidewall 120 close to the third sidewall 130, as shown in fig. 5.

Referring to fig. 1 to 9, the wind-shielding rib 600 of the present embodiment further includes a third wind-shielding rib 630 and a fourth wind-shielding rib 640. Wherein, one end of the third wind blocking rib 630 is connected with the second end of the first wind blocking rib 610, and the other end of the third wind blocking rib 630 extends to the fourth sidewall 140. One end of the fourth wind-blocking rib 640 is connected to the second end of the second wind-blocking rib 620, the other end of the fourth wind-blocking rib 640 extends to the second sidewall 120, and a second wind-storage area 152 is formed between the second wind-blocking rib 620, the fourth wind-blocking rib 640 and the second section 122 of the second sidewall 120.

Specifically, the fourth wind blocking rib 640 is disposed opposite to the first sidewall 110, so that the second wind storage area 152 is formed between the second wind blocking rib 620, the fourth wind blocking rib 640 and the second section 122 of the second sidewall 120, thereby preventing cold wind entering the second wind storage area 152 from the second wind inlet 400 or cooling wind flowing from the first wind storage area 151 to the second wind storage area 152 from flowing to other areas in the bottom case 100, in this embodiment, the first wind storage area 151 and the second wind storage area 152 are effectively isolated from other areas of the bottom case 100, so that the cool air entering the first air storage zone 151 and the second air storage zone 152 enters the fan cavity of the heat dissipation fan 200 only through the air inlet, therefore, the air quantity entering the heat radiation fan 200 is increased, more cooling air can be blown to other heating elements such as the coil panel 700 under the acceleration of the heat radiation fan 200, and the overall heat radiation efficiency of the induction cooker is further improved.

In addition, the fourth wind blocking rib 630 prevents the hot wind flowing through the coil panel 700 from flowing to the left again and entering the heat dissipation fan 200 through the second wind inlet 650 or the first wind inlet 660, so that the wind entering the heat dissipation fan 200 is cold wind.

Referring to fig. 1 to 7, when the second end of the second wind blocking rib 620 is located on the outer sidewall of the heat dissipation fan 200, the second wind storage area 152 formed between the second wind blocking rib 620, the fourth wind blocking rib 640 and the second section 122 of the second sidewall 120 is completely located between the fan cavity 210 of the heat dissipation fan 200 and the second sidewall 120, in this case, the second wind inlets 400 may be uniformly arranged on the second section of the second sidewall 120 on the side of the fourth wind blocking rib 640 facing the first sidewall 110 along the length direction, so as to increase the wind intake.

Referring to fig. 8 and 9, when the second end of the second wind blocking rib 620 extends out of a side of the heat dissipation fan 200 away from the first side wall 110, a side of the second side wall 120, which is located on the fourth wind blocking rib 640 and faces the first side wall 110, is located in the second wind storage area 152, and a second wind inlet 400 may be uniformly arranged on a portion of the second side wall 120, which is located on the second wind storage area 152, so as to increase a wind inlet amount.

Specifically, when the fan is installed, the distance between the fourth wind-blocking rib 640 and the first sidewall 110 gradually increases from the fan cavity 210 of the heat dissipation fan 200 to the second sidewall 120, that is, the fourth wind-blocking rib 640 is an inclined surface inclined toward the second sidewall 120. Thus, the cold air entering the second air storage area 152 through the second air inlet 400 can enter the fan cavity 210 of the heat dissipation fan 200 through the second air inlet 660 under the guidance of the inclined plane formed by the fourth wind blocking rib 640, and the flow rate of the cold air entering the heat dissipation fan 200 in the second air storage area 152 is increased.

Meanwhile, due to the inclined surface guide of the fourth wind blocking rib 640, the collision between the cooling air entering the second wind storage area 152 from the second wind inlet 400 and other side walls outside the second wind inlet 660 is also reduced, so that the wind consumption is reduced, the cooling air volume entering the heat dissipation fan 200 is increased, and the heat dissipation efficiency of the heating elements such as the coil panel 700 is ensured.

The inclination angle of the fourth wind-blocking rib 640 is not limited in this embodiment, for example, the included angle between the fourth wind-blocking rib 640 and the second sidewall 120 may be an appropriate angle value smaller than 90 ° such as 25 °, 45 °, or 80 °.

In a specific arrangement, two ends of the fourth wind blocking rib 640 may extend to the housing of the heat dissipation fan 200 and the second sidewall 120, respectively, and certainly, a gap may be formed between the two ends of the fourth wind blocking rib 640 and the housing of the heat dissipation fan 200 and the second sidewall 120.

The fourth wind-shielding rib 640 of the present embodiment has an extension length of 10mm to 60 mm. Like this, guaranteeing this fourth wind-break muscle 640 to the second wind-storage area 152 with other regional isolation effect, guaranteed the structural strength of this fourth wind-break muscle 640 moreover, avoid this fourth wind-break muscle 640 to take place to buckle under the impact of air current and break off even and influence the effect that blocks to the air current.

The third wind-blocking rib 630 of this embodiment is disposed opposite to the first sidewall 110, the third wind-blocking rib 630, the first wind-blocking rib 610, the first segment 121 of the second sidewall 120, the first sidewall 110, and a part of the fourth sidewall 140 jointly enclose the first wind-storage area 151, in other words, the third wind-blocking rib 630 effectively isolates the first wind-storage area 151 from the second area 160, so that the cooling wind entering the first wind-storage area 151 through the first wind inlet 300 only directly enters the fan cavity 210 of the second area 160 through the wind inlet, thereby increasing the cooling wind volume entering the fan cavity 210 of the heat dissipation fan 200.

Referring to fig. 1 to 9, the display panel 810 is specifically disposed in the first air storage region 151 between the third wind blocking rib 630 and the first sidewall 110, so that cold wind entering the first air storage region 151 through the first air inlet 300 can directly dissipate heat of the display panel 810, and then enter the fan cavity 210 of the heat dissipation fan 200 of the second region 160, so as to dissipate heat of other heating elements of the induction cooker, and the temperature of the cold wind does not rise significantly after passing through the display panel 810, thereby effectively dissipating heat of subsequent heating elements.

In addition, since the first air storage area 151, on which the display panel 810 is mounted, is communicated with the second air storage area 152 through the communication channel 153, a part of the cooling air entering the second air storage area 152 from the second air inlet 400 can also enter the first air storage area 151 to dissipate heat of the display panel 810, thereby improving heat dissipation efficiency of the display panel 810.

Referring to fig. 1 to 3, in the electromagnetic oven of the present embodiment, the heat dissipation fan 200, the coil panel 700, and the power board 820 are arranged in a triangle, the coil panel 700 is located between the heat dissipation fan 200 and the third sidewall 130, and the power board 820 is located between the heat dissipation fan 200 and the fourth sidewall 140. An outlet 500 is formed on the third sidewall 130 and/or the fourth sidewall 140, and the outlet 500 is disposed away from the first inlet 300 and the second inlet 400. The arrangement is such that a part of the wind blown out through the heat dissipation fan 200 is blown toward the coil panel 700, a part is blown toward the power supply board 820, and then the hot wind is directly blown out from the outlet 500 at the rear portion of the bottom chassis 100.

In some examples, the air outlets 500 are disposed on the third sidewall 130 and the fourth sidewall 140, and a part of the air blown by the heat dissipation fan 200 blows toward the coil panel 700, and after the coil panel 700 is cooled, the air is directly discharged through the air outlet 500 on the third sidewall 130; another part of the air blown out by the cooling fan 200 is blown toward the power board 820, passes through the heat sink located at the front end of the power board 820, and then passes through the remaining power boards 820 to cool the power board 820, and is directly discharged through the air outlet 500 on the fourth side wall 140.

Because the air outlets 500 are all arranged at the rear positions, the situation that air blown out from the heat dissipation fan 200 is directly discharged from the air outlets 500 without effectively dissipating heat of the coil panel 700 and the power supply board 820 is effectively avoided, so that waste of cooling air is prevented, and effective cooling of the coil panel 700 and the power supply board 820 is guaranteed.

Referring to fig. 2, in the present embodiment, a baffle 161 is disposed between the fan chamber 210 of the heat dissipation fan 200 and the coil panel 700; and/or a baffle plate 161 is arranged between the fan cavity 210 of the heat radiation fan 200 and the power panel; a fan outlet is formed between the upper end surface of the baffle 161 and the panel of the induction cooker.

The baffle 161 is disposed between the fan chamber 210 of the heat dissipation fan 200 and the coil panel 700. Due to the arrangement of the baffle 161, cold air in the heat dissipation fan 200 is fully accelerated and then blown out from the fan air outlet at the top end of the baffle 161, so that the blowing speed of the cold air is increased, the flow resistance entering the coil disc 700 is reduced, and the heat dissipation efficiency is further ensured. The baffle 161 can make the cooling air flow according to a preset path, that is, after the cooling air in the heat dissipation fan 200 is blown out through the fan outlet, the cooling air is blocked by the baffle 161 to flow to the area of the coil panel 700 close to the right side, so that a part of the cooling air is prevented from being blown out from the gap on the left side of the coil panel 700 and influencing the air volume entering the coil panel 700 and the power panel 820.

The baffle 161 extends between the coil panel 700 and the power board 820, so that the heat radiation between the coil panel 700 and the power board 820 can be reduced to a certain extent, and the mutual influence of the heat of the coil panel 700 and the power board 820 is avoided.

Further, the upper end surface of the baffle 161 is flush with or higher than the lowest surface of the fan blade of the heat dissipation fan 200.

It can be understood that the lowest surface of the fan blades of the heat dissipation fan 200 is the air inlet surface of the heat dissipation fan 200. In the present embodiment, the baffle 161 is blocked between the air inlet surface of the heat dissipation fan 200 and the inner bottom wall of the bottom chassis 100, so as to prevent the cooling air that has not been accelerated in the heat dissipation fan 200 from being blown out through the gap between the lowest surface of the fan blade of the heat dissipation fan 200 and the inner bottom wall of the bottom chassis 100, thereby ensuring that the cooling air is blown out from the air outlet surface of the heat dissipation fan 200 at a high speed, smoothly flows through the coil panel 700 and the power board 820, and is discharged from the air outlet 500, effectively overcoming the resistance of flowing through the coil panel 700 and the power board 820, and ensuring the heat dissipation effect on the coil panel 700 and the power board 820.

Example two

Fig. 10 is a schematic view of the internal structure of the induction cooker with the rack-inverted blower according to the second embodiment; FIG. 11 is an enlarged partial view of FIG. 10; fig. 12 is a top view of fig. 10. Referring to fig. 10 to 12, unlike the first embodiment, in the present embodiment, a partition 154 is further disposed between the first side wall 110 and the third wind-blocking rib 630, one end of the partition 154 is connected to the third wind-blocking rib 630, the other end of the partition 154 is connected to the first side wall 110, and the first wind storage area 151 is located on a side of the partition 154 facing the second side wall 120. In the above structure, the first intake vent 300 is provided only in a region of one side of the partition 154 facing the second sidewall 120. Thus, the path of the cockroach entering the inside of the induction cooker is reduced.

Above-mentioned mode of setting has reduced the size space of first wind storage area 151 for first wind storage area 151 concentrates on the position of going into the wind gap, has increased the wind pressure in first wind storage area 151, thereby makes in the cold wind in first wind storage area 151 can get into the second region 160 fast through first wind gap 650, has reduced the resistance that gets into the second region 160 simultaneously, thereby has increased the cold wind volume that first wind storage area 151 got into the second region 160. In addition, the arrangement mode further avoids the situation that the cold air in the part far away from the air inlet cannot completely reach the air inlet due to large air consumption because the space size of the first air storage area 151 is too large, so that the distance between the cold air and the air inlet is too long.

It is understood that the partition 154 may be disposed at any position between the first air inlet 650 and the fourth sidewall 140, for example, the partition 154 may be disposed near the first air inlet 650, at one half of the third wind blocking rib 630, or near the fourth sidewall 140. The present embodiment is not limited to a specific position of the partition 154.

The display panel 810 of the present embodiment is located above the partition 154, and a portion of the display panel 810 is located in the first wind storage area 151, and another portion is located on a side of the partition 154 facing away from the second sidewall 120. Thus, in a specific arrangement, a component having a high heat dissipation capacity on the display panel 810 can be placed in the first air storage region 151 to ensure effective heat dissipation to the display panel. For example, a portion provided with an indicator lamp may be located within the first wind storage area 151.

In addition, the display panel 810 is disposed above the spacer 154, and the installation space of the display panel 810 is increased, not only increasing the size setting upper limit of the display panel 810, that is, the large-sized display panel 810 can be stably installed above the spacer 154, but also facilitating the installation of the display panel 810.

Referring to fig. 13 to 18, the present embodiment is different from the second embodiment in that the display panel 810 is disposed at a different position.

Referring to fig. 13 to 15, as a possible arrangement, the display panel 810 is located on a side of the partition 154 away from the second side wall 120, that is, the display panel 810 is located in the non-wind storage area, so as to prevent the display panel 810 from blocking the flow of the cold wind in the first wind storage area 151, thereby reducing the loss of the cold wind in the first wind storage area 151 and further increasing the amount of the cooling wind entering the second area 160.

Referring to fig. 16 to 18, the display panel 810 is disposed on a side of the partition 154 facing the second sidewall 120, so that the cold air in the first air storage region 151 can effectively dissipate heat of the display panel 810 before entering the second region 160, thereby improving heat dissipation efficiency of the display panel 810.
