Referring to fig. 1 to 5, the present embodiment provides an induction cooker.

The induction cooker may specifically include: a bottom case 1, a panel (not shown), a coil panel 2, a heat dissipation fan 4, a lamp panel 32, a circuit board assembly 31, and the like. The bottom shell 1 is provided with an accommodating cavity, the coil panel 2, the circuit board assembly 31, the heat dissipation fan 4 and the lamp panel 32 are located in the accommodating cavity, and the panel cover is arranged on the bottom shell 1. Wherein, the panel can be ceramic panel, also can be glass panels, the utility model discloses do not limit to the material of panel. The lamp panel 32 may be provided with a key, an indicator light, and other control devices and/or a display device.

The bottom case 1 specifically includes a lower cover 12 and an upper cover 11 located above the lower cover 12. In the present embodiment, the lower cover 12 is a cavity structure, the upper cover 11 is a frame-shaped cover, and the sidewall of the lower cover 12 is formed as at least a part of the sidewall of the bottom case 1. In other implementations, the lower cover 12 may specifically include a lower cover and a middle cover, the middle cover is disposed around the periphery of the lower cover, and a side wall of the middle cover is formed as at least a partial side wall of the bottom case 1. The upper cover 11 and the lower cover 12 enclose the accommodating cavity capable of accommodating the coil panel 2, the heat dissipation fan 4, the lamp panel 32 and the circuit board assembly 31.

Wherein, the bottom case 1 is provided with a mounting post 111, in this embodiment, the mounting post 111 can be specifically used to connect the upper cover 11 and the lower cover 12. In other implementation manners, the mounting posts 111 may also be used to fix the lamp panel 32, that is, fix the lamp panel 32 on the bottom case 1, or the mounting posts 111 are used to connect the upper cover 11 and the lower cover 12 and fix the lamp panel 32 at the same time. For example, the number of the mounting posts 111 is multiple, one of the mounting posts 111 is used to connect the upper cover 11 and the lower cover 12, and one or more of the mounting posts are used to fix the lamp panel 32.

The coil panel 2 may specifically include a coil panel frame and a coil wound on the coil panel frame, and the coil is electrically connected to the circuit board assembly 31. When the induction cooker works, the coil panel 2 and the circuit board assembly 31 are main heating elements, and the heat dissipation fan 4 is used for dissipating heat of the heating elements such as the coil panel 2 and the circuit board assembly 31. When the induction cooker is used for cooking, a pot filled with food materials is placed on a panel of the induction cooker, the induction cooker is electrified, namely, high-frequency current flows through coils on the coil panel 2, and generated magnetic lines cut the pot, so that countless small eddy currents are formed on the bottom surface of the pot, and the pot is heated. The circuit board assembly 31 specifically includes a circuit board. Generally, an Insulated Gate Bipolar Transistor (IGBT) and an electronic element such as a rectifier bridge stack are disposed on the circuit board, the IGBT and the rectifier bridge stack generate heat greatly, and in order to further improve the heat dissipation effect of the electronic element, a heat sink may be disposed on the circuit board, so that the heat sink contacts the electronic element on the circuit board, and heat generated by the electronic element is rapidly transferred to the heat sink, and is dissipated through the heat sink.

Wherein, the bottom shell 1 is provided with an air inlet 110 and an air outlet 120, and it can be understood that the air inlet 110 and the air outlet 120 are both communicated with the outside. When the induction cooker works, cooling air outside the induction cooker enters the bottom case 1 from the air inlet 110 under the action of the heat dissipation fan 4, is pressurized by the heat dissipation fan 4 and then blows towards the coil panel 2, the circuit board assembly 31 and the like, heat of heating elements such as the coil panel 2 and the circuit board assembly 31 is taken away, and then hot air is blown out from the air outlet 120, so that heat dissipation of the induction cooker is realized.

Because the air inlet 110 of prior art's electromagnetism stove sets up on the diapire of drain pan 1, outside cooling air of electromagnetism stove gets into in the drain pan 1 by the air inlet 110 on the diapire of drain pan 1 under the effect of cooling blower 4, but the diapire of drain pan 1 is nearer apart from the desktop, especially to the electromagnetism stove that the appearance is thinner, the space of its diapire to desktop is narrow and small very much, cooling blower 4 during operation, easily inhale ponding etc. on the desktop to the inner chamber of drain pan 1, lead to the phenomenon that the electron device in the drain pan 1 met water and wet or take place the short circuit to appear, lead to the electromagnetism stove to damage and the emergence of unsafe accident. Based on this, in the present embodiment, at least a portion of the air inlet holes 110 are opened on the side wall of the bottom case 1. An air inlet area is formed between the air inlet 110 on the side wall of the bottom case 1 and the heat dissipation fan 4, and a portion of the air inlet area close to the heat dissipation fan 4 forms a main air inlet area 101. That is, the cooling air entering from the air inlet holes 110 on the side wall of the bottom case 1 enters the fan cavity of the heat dissipation fan 4 under the action of the heat dissipation fan 4, and then blows toward the coil panel 2, the circuit board assembly 31, and the like. Wherein, the cooling air mainly enters into the fan cavity of the heat dissipation fan 4 from the air inlet holes 110 corresponding to the main air inlet area 101.

It can be understood that the air intake and the air intake speed of the main air intake area 101 are main factors affecting the heat dissipation effect, and the air intake of the main air intake area 101 is large and the air intake is smooth, so that the cooling air volume and the air speed entering the fan cavity of the heat dissipation fan 4 are correspondingly increased, thereby ensuring a good heat dissipation effect.

At least part of fresh air inlet 110 is seted up on the lateral wall of drain pan 1, compare with the scheme that all fresh air inlets of prior art set up at the diapire of drain pan, because the utility model provides a this part fresh air inlet 110 is higher than the position of drain pan 1 diapire apart from the distance of desktop, and fresh air inlet 110 locates the inside and outside pressure differential less to can avoid the ponding of electromagnetism stove during operation desktop to a certain extent to be inhaled the condition emergence in the drain pan 1, prolonged the life of electron device in the electromagnetism stove, avoid the emergence of dangerous accident.

In the present embodiment, all of the air inlet holes 110 are opened in the side wall of the bottom case 1. Of course, in other implementations, a portion of the air inlet holes 110 may be located on the side wall of the bottom case 1, and a portion of the air inlet holes 110 may be located on the bottom wall of the bottom case 1. Compare with the scheme that prior art's fresh air inlet all was located the diapire, still can avoid desktop ponding to a certain extent to be inhaled in the drain pan.

Meanwhile, in order to avoid the blocking of the cooling air in the main air intake area 101 by the mounting posts 111 on the bottom case 1 for connecting the upper cover 11 and the lower cover 12 or the mounting posts 111 for fixing the lamp panel 32, in this embodiment, the mounting posts 111 are specifically disposed in an area outside the main air intake area 101, so that the blocking of the cooling air in the main air intake area 101 by the mounting posts 111 can be avoided, and the cooling air entering from the air intake holes 110 can smoothly flow from the main air intake area 101 to the fan cavity of the cooling fan 4, thereby enhancing the overall smoothness of the air intake in the main air intake area 101, ensuring the air intake amount and the air speed of the cooling air, and improving the heat dissipation effect of the induction cooker.

During specific implementation, the mounting column 111 is provided with screw holes, the parts connected with the mounting column are provided with screw holes, and the two parts are connected through screws penetrating through the two screw holes. Of course, in other implementation manners, the mounting post 111 may have a buckle, and a part connected with the buckle has a clamping hole or a clamping groove that can be engaged with the buckle in a matching manner, so that the two parts are connected by the cooperation of the clamping hole/clamping groove and the buckle.

In the present embodiment, the mounting post 111 is used to connect the upper cover 11 and the lower cover 12. Among them, the mounting post 111 is specifically provided on the lower cover 12. The mounting post 111 is provided with a first screw hole, a second screw hole is arranged at the position of the upper cover 11 corresponding to the first screw hole, and the upper cover 11 and the lower cover 12 are connected through screws penetrating through the first screw hole and the second screw hole. This makes the connection of the upper and lower covers 11 and 12 more convenient and more stable. Of course, the mounting post 111 may be provided on the upper cover 11.

When there are a plurality of mounting posts 111, all of the mounting posts 111 are located in an area outside the main intake area 101.

Compared with the scheme that all the air inlet holes in the prior art are formed in the bottom wall of the bottom shell, because at least part of the air inlet holes 110 in the embodiment are located in the side wall of the bottom shell 1, the distance from the part of the air inlet holes 110 to the desktop is higher than the position of the bottom wall of the bottom shell 1, so that the condition that water accumulated on the desktop is sucked into the bottom shell 1 when the induction cooker works can be avoided, the service life of electronic devices in the induction cooker is prolonged, and unsafe accidents are avoided. Meanwhile, the mounting posts 111 used for connecting the upper cover 11 and the lower cover 12 or for fixing the lamp panel 32 in the bottom case 1 are arranged in the area outside the main air inlet area 101, so that the situation that the mounting posts 111 block the air in the main air inlet area 101 can be avoided, the cooling wind entering from the air inlet holes 110 can smoothly flow from the main air inlet area 101 to the fan cavity of the cooling fan 4, the overall smoothness of the air inlet of the main air inlet area 101 is enhanced, the air inlet amount and the air speed of the cooling wind are ensured, and the heat dissipation effect of the induction cooker is improved.

Specifically, the side wall of bottom shell 1 includes a first side wall 121 and a second side wall 122 connected to each other, and first side wall 121 includes a first side wall section 1211 connected to second side wall 122 and a second side wall section 1212 remote from second side wall 122. At least a portion of the air inlet openings 110 is formed in the first sidewall 1211, the heat dissipation fan 4 is disposed adjacent to the first sidewall 1211, and at least a portion of the main air inlet area 101 is formed between the first sidewall 1211 and the heat dissipation fan 4.

For example, the first sidewall section 1211 and the second sidewall section 1212 may be respectively located on both sides of a center line of the first sidewall 121, and particularly, the mounting post 111 may be disposed corresponding to the center line of the first sidewall 121. Through corresponding the setting with the central line of erection column 111 and first lateral wall 121, both avoided erection column 111 to lead to the fact the fender to establish to the air inlet of main air inlet district 101 like this, and when erection column 111 connects upper cover 11 and lower cover 12, so set up the overall stability after making upper cover 11 and lower cover 12 connect better, perhaps make lamp plate 32 more stable.

The second side wall 122 includes a third side wall section 1221 connected to the first side wall section 1211, at least a portion of the third side wall section 1221 has an air inlet opening 110, the heat dissipation fan 4 is disposed near a connection between the first side wall section 1211 and the third side wall section 1221, and the main air inlet area 101 is formed among the first side wall section 1211, the third side wall section 1221 and the heat dissipation fan 4.

The heat dissipation fan 4 is disposed near the connection between the first sidewall 1211 and the third sidewall 1221, and the air inlet holes 110 are respectively formed in the first sidewall 1211 and the third sidewall 1221, so as to increase the area of the air inlet holes 110, when the first sidewall 1211 and the third sidewall 1221 face different directions, that is, cooling air in different directions outside the induction cooker can enter the fan cavity of the heat dissipation fan 4 from the air inlet holes 110 of the first sidewall 1211 and the air inlet holes 110 of the second sidewall 1212, respectively, thereby increasing the overall air inlet amount and further improving the heat dissipation efficiency.

In a specific implementation, the second side wall section 1212 may further be provided with an air inlet hole 110, and the secondary air inlet region 102 is formed between the air inlet hole 110 on the second side wall section 1212 and the heat dissipation fan 4. That is to say, by forming the air inlet holes 110 on the second side wall section 1212, the area of the whole air inlet hole 110 on the bottom case 1 is further increased, that is, the air inlet duct is increased, so that the cooling air outside the induction cooker can enter the fan cavity of the heat dissipation fan 4 from the air inlet holes 110 corresponding to the main air inlet area 101, and can also enter the fan cavity of the heat dissipation fan 4 from the air inlet holes 110 corresponding to the secondary air inlet area 102, thereby further improving the heat dissipation effect.

In one possible implementation, the mounting posts 111 can be located in the secondary air intake area 102. In another possible implementation, the mounting post 111 can be located between the primary air intake zone 101 and the secondary air intake zone 102. The arrangement enables the mounting column 111 not to affect the air intake of the main air intake area 101, and facilitates the connection between the upper cover 11 and the lower cover 12 or the fixation of the lamp panel 32.

Further, a connecting structure for connecting the lower cover 12 and the upper cover 11 is arranged in the secondary air inlet area 102; the connecting structure comprises a buckle 62 arranged on one of the lower cover 12 and the upper cover 11 and a clamping hole 61 arranged on the other of the upper cover 11 and the lower cover 12, and the buckle 62 is matched and clamped with the clamping hole 61. In the present embodiment, specifically, the lower cover 12 has a locking protrusion extending upward, the locking protrusion has a locking hole 61, and the upper cover 11 has a locking buckle 62. This further improves the stability of the connection of the upper cover 11 and the lower cover 12 without affecting the intake of the main intake area 101. When the mounting posts 111 are used to connect the upper cover 11 and the lower cover 12, the upper cover 11 and the lower cover 12 are connected by the mounting posts 111 and the above-mentioned connecting structure, so that the connection between the upper cover 11 and the lower cover 12 is more secure.

Preferably, the first sidewall 121 may be a front sidewall facing the user. That is, when the user cooks using the induction cooker, the first sidewall 121 faces the user. Because the first side wall 121 faces the user, at least part of the air inlet holes 110 are formed in the first side wall 121, the user can visually and conveniently see the air inlet holes 110, and easily see whether the air inlet holes 110 are blocked, so that the air inlet holes 110 can be cleaned in time, and the influence on air inlet is avoided. In addition, when the air inlet 110 is disposed on the first side wall 121, the distance from the air inlet 110 to the table top is greater than the position of the bottom wall of the bottom case 1, so that the phenomenon that the accumulated water on the table top is sucked into the bottom case 1 when the induction cooker works can be avoided. Moreover, the air inlet holes 110 on the first side wall 121 are disposed close to the operation area (i.e. the front side of the induction cooker), that is, the pot placed on the panel of the induction cooker is far away from the part of the air inlet holes 110, so that even if the pot overflow phenomenon occurs, the soup overflowing from the pot is not easy to flow into the inner cavity of the bottom case 1 through the part of the air inlet holes 110, and further, the devices in the induction cooker are effectively protected, and unsafe accidents are avoided.

In this embodiment, the heat dissipation fan 4 is specifically an axial flow fan, and the manufacturing cost of the induction cooker is reduced by setting the fan as the axial flow fan on the basis of ensuring the heat dissipation effect. Illustratively, the lower surface of the cooling fan 4 forms an air inlet surface, and the upper surface of the cooling fan 4 forms an air outlet surface, that is, the air inlet direction is downward air inlet and upward air outlet. The cooling air enters the bottom of the heat dissipation fan 4 and then blows from the top of the heat dissipation fan 4 toward the heat generating elements.

Can also set up the wind-break muscle in the drain pan 1, during concrete implementation, the wind-break muscle can with drain pan 1 integrated into one piece, for example, when drain pan 1 is plastic drain pan 1, when moulding plastics drain pan 1, integrated injection moulding wind-break muscle in drain pan 1. Of course, the wind shielding rib can also be fixed in the bottom case 1 subsequently, and the utility model discloses do not limit this.

In the present embodiment, the wind blocking rib specifically includes a first wind blocking rib 51 disposed between the first side wall 121 and the heat dissipation fan 4, and a second wind blocking rib 52 disposed between the second side wall and the heat dissipation fan 4. The first air blocking rib 51 is provided with a first air vent 501, and the second air blocking rib 52 is provided with a second air vent 502. The cooling air entering from the air inlet holes 110 on the first side wall 121 enters the fan cavity of the heat dissipation fan 4 through the first vent 501, and the cooling air entering from the air inlet holes 110 on the second side wall 122 enters the fan cavity of the heat dissipation fan 4 through the second vent 502.

By arranging the wind blocking ribs, cooling air entering the fan cavity of the heat dissipation fan 4 can be prevented from being blown back to the air inlet area. Meanwhile, the first ventilation opening 501 and the second ventilation opening 502 are arranged on the wind blocking rib, so that cooling air in an air inlet area can smoothly enter the heat dissipation fan 4 through the first ventilation opening 501 and the second ventilation opening 502, the air quantity blowing to the heating element is ensured, the cooling air is effectively utilized, and the heat dissipation effect is further improved.

Preferably, a first ventilation opening 501 is formed between the first wind blocking rib 51 and the inner bottom wall of the bottom case 1, and a second ventilation opening 502 is formed between the second wind blocking rib 52 and the inner bottom wall of the bottom case 1, so that the cooling wind entering from the ventilation opening can directly reach the wind inlet surface of the heat dissipation fan 4 as much as possible, and then blows to the heating element under the action of the heat dissipation fan 4, thereby further improving the speed and smoothness of wind inlet.

The top end of the first ventilation opening 501 may or may not extend to the top of the first wind-blocking rib 51, and the top end of the second ventilation opening 502 may or may not extend to the top of the second wind-blocking rib 52. Preferably, the plane on which the top ends of the first ventilation opening 501 and the second ventilation opening 502 are located may be no higher than the plane on which the lower surface of the heat dissipation fan 4 is located. That is, the plane where the top end of the first air vent 501 and the top end of the second air vent 502 are located is not higher than the lowest position of the air intake surface of the heat dissipation fan 4. If the plane of the top end of the vent is set to be higher than the plane of the lower surface of the heat dissipation fan 4, the heat dissipation fan 4 may blow part of the wind back to the air intake area, and then the part of the wind cannot blow to the heating elements such as the coil panel 2 and the circuit board assembly 31, and the amount of wind blowing to the heating elements becomes small.

In other embodiments, only the first wind-blocking bead 51 or only the second wind-blocking bead 52 may be provided.

The air inlet 110 specifically includes a plurality of holes, and the plurality of holes are arranged on the bottom case 1 at intervals, for example, the plurality of holes are arranged in a grid shape, which not only ensures the intake air amount and the intake air uniformity, but also improves the aesthetic feeling of the appearance of the induction cooker. The plurality of holes can also be arranged in a plurality of rows and columns, in a ring shape, and the like. Each hole may be in the shape of a strip, a circle, etc., and the present invention is not limited thereto. The air outlet holes 120 may also be disposed in a plurality of shapes, for example, the air outlet holes 120 are arranged at intervals on the side wall of the bottom case 1 away from the user, for example, the air outlet holes 120 are arranged in a grid shape along the length direction of the side wall, and/or the air outlet holes 120 are arranged at intervals on the bottom wall of the bottom case 1 away from the air inlet hole 110, for example, the air outlet holes 120 are arranged in a radial shape.
