Wherein, the panel 10 is covered on the top of the bottom case 1. The bottom case 1 may specifically include a lower cover 11 and an upper cover 12 connected above the lower cover 11. An air inlet and an air outlet are arranged on the bottom shell 1. The coil panel 2, the power panel 31, the display panel 33 and the heat dissipation fan 4 are located in an accommodating cavity enclosed by the bottom case 1 and the panel 10.

The panel 10 may be a ceramic panel or a glass panel, and the material of the panel 10 is not limited in the present invention. Wherein, the edge of panel 10 can also set up lock ring 101, and lock ring 101 specifically can be the steel ring, supports the pan through lock ring 101, and lock ring 101 can carry out effective protection to the edge of panel 10, can reduce the transmission of the temperature of pan to panel 10 to a certain extent moreover. The display panel 33 may be provided with a key, an indicator light, and/or other operation and/or display devices. Specifically, the bottom case 1 has an operation knob 13 thereon, and the electromagnetic oven can be turned on or off or function selection can be performed by the operation knob 13. The operation knob 13 may be replaced with a touch key.

The coil panel 2 may specifically include a panel frame and a coil wound on the panel frame, wherein the coil is electrically connected to the power supply board 31. The heat dissipation fan 4 is used for dissipating heat of the coil panel 2, the power board 31, and the like, and the heat dissipation fan 4 is electrically connected to the power board 31. When the induction cooker is used for cooking, a pot filled with food materials is placed on the panel 10, the induction cooker is electrified, namely, high-frequency current flows through the 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.

In order to facilitate the connection between the display panel 33 and the power supply board 31, in the present embodiment, a support 30 is provided in the bottom chassis 1, and the power supply board 31 and the display panel 33 are fixed to the support 30. The support 30 has a first side and a second side opposite to each other, the power board 31 is specifically fixed on the first side of the support 30, and the display board 33 is fixed on the second side of the support 30, that is, the display board 33 is fixed on a side of the support 30 facing away from the power board 31.

The power panel 31 and the display panel 33 are arranged on the two opposite sides of the bracket 30, namely the power panel 31 and the display panel 33 are arranged back to back, so that the distance between the power panel 31 and the display panel 33 is shortened, and the display panel 33 and the power panel 31 are more conveniently connected; moreover, during assembly, the power supply board 31 and the display board 33 can be firstly installed on the bracket 30, and then the whole body provided with the power supply board 31 and the display board 33 is installed on the bracket 30, so that the assembly is more convenient. In addition, the display panel 33 and the power panel 30 are disposed on the same bracket 30, and the display panel 33 and the power panel 31 are disposed back to back, so that the space in the bottom case 1 is effectively saved, and the induction cooker is developed toward small volume.

In the present embodiment, the coil disk 2 is embodied as a concave-concave coil disk, and the panel 10 is embodied as a concave-concave panel. That is, the induction cooker of the present embodiment may be a concave induction cooker. Of course, the induction cooker may also be a planar induction cooker, i.e., the coil panel is a planar coil panel and the panel is a flat plate.

Specifically, at least one mounting hole 301 is formed in the bracket 30, and the mounting hole 301 is used for connecting the power panel 31 or the display panel 33. For example, the power board 31 has a through hole 310, when the power board 31 is fixed on the first side of the bracket 30, the through hole 310 on the power board 31 is aligned with the mounting hole 301 on the bracket 30, and then the power board 31 is connected to the bracket 30 by screws inserted into the through hole 310 and the mounting hole 301. For another example, the display panel 33 has a through hole, when the display panel 33 is fixed on the second side of the bracket 30, the through hole of the display panel 33 is aligned with the mounting hole 301 of the bracket 30, and then the display panel 33 is connected to the bracket 30 by a screw inserted through the through hole of the display panel 33 and the mounting hole 301.

In another embodiment, the power board 31 may have an engaging portion that can be engaged with the mounting hole 301, and when mounting, the engaging portion of the power board 31 may be aligned with the mounting hole of the bracket 30, and the engaging portion may be engaged with the mounting hole 301, so that the power board 31 is fixed to the first side of the bracket 30. The display panel 33 may also be fixed to the second side of the support 30 in this way.

Specifically, the support 30 has an overlapping region, which is a region where a vertical projection of the display panel 33 on the support 30 and a vertical projection of the power supply panel 31 on the support 30 coincide with each other; the mounting holes 301 are disposed at and/or near the overlapping region, and the mounting holes 301 are blind holes. It will be appreciated that the blind holes are holes that do not extend through the first and second sides of the bracket 30.

Wherein, when the mounting hole 301 is used for connecting the power supply board 31, the mounting hole 301 is a blind hole opening toward the power supply board 31. When the mounting hole 301 is used to connect the display panel 33, the mounting hole 301 is a blind hole that opens toward the display panel 33.

The mounting holes 301 arranged in the overlapping area and/or near the overlapping area are blind holes, so that the mounting holes 301 do not penetrate through the support 30, and therefore on the basis of realizing connection of the power panel 31 or the display panel 33, the display panel 33 and the power panel 31 which are positioned on the two opposite sides of the support 30 are isolated, and the phenomenon that the normal use of the display panel 33 or the power panel 31 and unsafe accidents are influenced due to the fact that the electric gap and the creepage distance between the display panel 33 and the power panel 31 are small is avoided.

Specifically, the bracket 30 may be provided with a plurality of mounting holes 301 for connecting the power supply board 31, and the bracket 30 may also be provided with a plurality of mounting holes 301 for connecting the display board 33.

Since the plate surface of the bracket 30 is generally made thin, in order to ensure the hole depth of the mounting hole 301, in the present embodiment, referring to fig. 7, the mounting hole 301 is formed by partially recessing the bracket 30 toward the first side or the second side of the bracket 30. Specifically, when the mounting hole 301 is used to connect the power supply board 31, the mounting hole 301 may be formed by recessing the bracket 30 toward the second side thereof, thereby forming a blind hole opening toward the power supply board 31. When the mounting hole 301 is used to connect the display panel 33, the mounting hole 301 may be formed by recessing the bracket 30 toward the first side thereof, thereby forming a blind hole that opens toward the display panel 33. This can increase the hole depth of the mounting hole 301 without changing the thickness of the bracket 30, making it easier and more secure to connect the bracket 30 to the display panel 33 or the bracket 30 to the power supply board 31.

The thickness of the bottom wall 300 of the blind hole may be set to be not less than 2mm in particular to further secure the electric gap and the creepage distance between the display panel 33 and the power supply board 31 located at both sides of the stand 30.

With continued reference to fig. 7, the opening edge of the mounting hole 301 may also be extended away from the mounting hole 301, so that the hole depth of the mounting hole 301 may be increased without changing the thickness of the bracket 30, so that the connection between the bracket 30 and the display panel 33 or the bracket 30 and the power supply board 31 is easier and more secure.

Since the mounting hole 301 is located at a position of the bracket 30 away from the overlapping area, that is, the mounting hole 301 is located at a position away from the overlapping area, that is, away from the electrical pin of the display panel 33 and/or the electrical pin of the power supply board 31, and only a part of the power supply board 31 or only a part of the display panel 33 is located at a part away from the overlapping area, the mounting hole 301 at the position can be set as a through hole penetrating through the first side and the second side of the bracket 30, so that the connection is more convenient, and the creepage distance and the electrical gap between the display panel 33 and the power supply board 31 are not affected.

It is understood that the mounting hole 301 is specifically used for connecting the power supply board 31 when the outer size of the display panel 33 is smaller than the power supply board 31. The mounting holes 301 are particularly used for connecting the display panel 33 when the outer dimensions of the display panel 33 are larger than the power supply board 31. Of course, the mounting hole 301 at this position may also be a blind hole.

The holder 30 has a clip 302 for fixing the power supply board 31 or the display board 33, and the clip 302 has an engaging surface 303. When the clip 302 is used to fix the power board 33, the clip 302 is disposed on the first side of the bracket 30 and extends in a direction away from the first side, and the engaging surface 303 presses the power board 31 against the first side of the bracket 30. When the latch 302 is used for fixing the display panel 33, the latch 302 is disposed on the second side of the bracket 30 and extends toward a direction away from the second side, and the latch surface 303 is used for pressing the display panel 33 on the second side of the bracket 30. The display panel 33 or the power supply board 31 is connected to the bracket 30 through the buckle 302, so that no hole needs to be formed in the bracket 30, the electric gap and the creepage distance between the display panel 33 and the power supply board 31 are not affected, and the requirement for the arrangement position of the buckle 302 is reduced.

Further, the bracket 30 is further provided with a limiting block 304 for limiting the power panel 31 or the display panel 33. Specifically, after the power board 31 is placed on the bracket 30 in place, for example, after the through hole 310 of the power board 31 is aligned with the mounting hole 301 of the bracket 30, the stopper 304 is just blocked at the edge of the power board 31, so as to position the power board 31, prevent the power board 31 from moving, and facilitate further fixing between the power board 31 and the bracket 30. Specifically, the limiting blocks 304 may be disposed on two opposite sides of the bracket 30 corresponding to the power panel 31 or the display panel 33.

It should be noted that, only the mounting hole 301, only the clip 302, or both the mounting hole 301 and the clip 302 may be provided on the bracket 30, so that the power panel 31 or the display panel 33 can be fixed.

In the present embodiment, the heat dissipation fan 4 is located between the power supply board 31 and the coil disk 2. The cooling fan 4 may comprise a fan support and fan blades located on the fan support. The heat radiation fan 4 can be an axial flow fan, and is low in cost and good in heat radiation effect. It should be noted that the heat dissipation fan 4 in this embodiment is located between the power board 31 and the coil panel 2, and the heat dissipation fan 4, the power board 31 and the coil panel 2 are not arranged in a triangle.

Referring to fig. 1 to 3, in the present embodiment, at least a portion of the power board 31 is located between the air inlet opening 110 and the air inlet surface of the heat dissipation fan 4, and the coil panel 2 is located on the air outlet side of the heat dissipation fan 4.

That is to say, when the electromagnetic oven works, cooling air outside the electromagnetic oven enters the bottom case 1 from the air inlet hole 110 under the action of the heat dissipation fan 4, because at least part of the power panel 31 is located between the air inlet hole 110 and the air inlet surface of the heat dissipation fan 4, at least part of the cooling air entering from the air inlet hole 110 passes through the power panel 31 first, heat of the power panel 31 is taken away, and then reaches the position of the heat dissipation fan 4 under the action of the heat dissipation fan 4, the cooling air is blown out from the air outlet surface of the heat dissipation fan 4, because the coil panel 2 is located at the air outlet side of the heat dissipation fan 4, the cooling air blown out from the air outlet surface of the heat dissipation fan 4 is blown towards the coil panel 2, so that the amount of the cooling air blown towards the coil panel 2 is larger, the heat dissipation effect of the coil panel 2 is improved, the cooling air takes away heat of the coil panel 2, and then hot air.

In this embodiment, although the cooling air passes through the power supply board 31 before reaching the coil panel 2, the coil panel 2 has a higher temperature resistance than the power supply board 31, and therefore, if the amount of air blown to the coil panel 2 is ensured to be larger and the wind force is more concentrated, the heat radiation effect of the coil panel 2 is ensured.

By positioning the heat dissipation fan 4 between the power panel 31 and the coil panel 2, at least part of the power panel 31 is positioned between the air inlet holes 110 and the air inlet surface of the heat dissipation fan 4, and the coil panel 2 is positioned on the air outlet side of the heat dissipation fan 4, so that cooling air entering from the air inlet holes 110 firstly passes through the power panel 31 and reaches the heat dissipation fan 4, and the cooling air blows towards the coil panel 2 under the action of the heat dissipation fan, thereby increasing the air volume blowing towards the coil panel 2, improving the heat dissipation effect of the coil panel 2, and simultaneously ensuring the heat dissipation of the power panel 31; compare with the scheme that the staggered floor set up about prior art coil panel and power strip, the utility model discloses as above set up still to a certain extent reduced the height of electromagnetism stove fuselage, make the electromagnetism stove can move towards frivolous development.

In this implementation, at least part of the air inlet openings 110 may be opened in particular in the bottom of the front side wall of the bottom shell 1 facing the user and/or in the bottom wall of the bottom shell 1 near the front side wall. The front side wall is the side wall facing the user when the user cooks. Illustratively, in the present embodiment, the side wall of the upper cover 12 and the side wall of the lower cover 11 together form a side wall of the bottom case 1.

In the present embodiment, the air inlet holes 110 may be formed in the lower cover 11, for example, in the bottom of the front side wall of the lower cover 11 facing the user and the bottom wall near the front side wall. Of course, the side walls of the upper cover 12 and the lower cover 11 may be provided with air inlet holes 110.

The air inlet holes 110 are arranged close to a user, so that the user can conveniently observe whether the air inlet holes 110 are blocked or not, and normal air inlet of the induction cooker is ensured. In addition, because the air inlet holes 110 are arranged close to the front side of the induction cooker, a pot placed on the induction cooker panel 10 is far away from the air inlet holes 110, even if the phenomenon of overflowing the pot occurs, soup overflowing from the pot is not easy to flow into the inner cavity of the bottom shell 1 from the air inlet holes 110, so that the devices in the induction cooker are effectively protected to a certain extent, and unsafe accidents are avoided.

Preferably, at least part of the air outlet opening 120 is formed in a side wall of the bottom case 1 opposite to the front side wall and/or in a bottom wall of the bottom case 1 remote from the air inlet opening 110.
