Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Fig. 1 is an explosion structure diagram of an induction cooker according to an embodiment of the present invention; fig. 2 is a schematic structural view of an upper cover and an insulating sheet of an induction cooker according to an embodiment of the present invention; fig. 3 is a schematic structural view of a lower surface of a display panel of an induction cooker according to an embodiment of the present invention; fig. 4 is a schematic structural view illustrating an insulating layer disposed on a lower surface of a display panel of an induction cooker according to an embodiment of the present invention; fig. 5 is a top view of an internal structure of a bottom case of an induction cooker according to an embodiment of the present invention. 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) covering the bottom case 1, a coil panel 2 located in the bottom case 1, a heat dissipation fan 4, a display panel 31, and a main control panel 32. 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 display panel 31 and the coil panel 2 are electrically connected to the main control panel 32. The display panel 31 may be provided with a key, an indicator light, and/or other operation and/or display devices.

The coil panel 2 may specifically include a coil panel frame and a coil wound on the coil panel frame, when the induction cooker works, the coil panel 2 and the main control board 32 are main heating elements, and the heat dissipation fan 4 is used for dissipating heat for the heating elements such as the coil panel 2 and the main control board 32. 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.

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 and then blows to the coil panel 2, the main control board 32 and the like, heat of heating elements such as the coil panel 2, the main control board 32 and the like 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.

The bottom case 1 may specifically include a lower cover 12 and an upper cover 11 positioned above the lower cover 12. Wherein, the upper cover can bond at the lower cover top, perhaps covers under through the fix with screw, the utility model discloses do not do the restriction to its fixed mode. Specifically, the lower cover 12 is provided with an air inlet 110. 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.

Because the display panel 31 is an electrified component, if water vapor, oil smoke or dust enters the bottom case from the air inlet hole, the water vapor, the oil smoke or the dust can directly fall on the display panel, so that the display panel is affected by damp or damaged, and the normal use of the induction cooker is affected.

In order to solve this problem, the induction cooker of the present embodiment further includes an insulating sheet 51 provided on the upper cover 11, the insulating sheet 51 being positioned between the display panel 31 and at least a portion of the air inlet holes 110. That is to say, through set up insulating piece 51 on upper cover 11, make insulating piece 51 be located between display panel 31 and at least partial fresh air inlet 110, namely, separate display panel 31 and at least partial fresh air inlet 110 through insulating piece 51, even there is steam, oil smoke or dust etc. to enter into the drain pan from this partial fresh air inlet 110 like this, because the existence of insulating piece 51, insulating piece 51 can carry out certain degree to at least partial steam, oil smoke or dust etc. and block, reduced steam, oil smoke or dust etc. directly to display panel 31 to a certain extent and lead to the display panel 31 to the probability that the condition that the display panel 31 wets or damages appears, effectively protected display panel 31. Because the air inlet holes 110 are arranged on the lower cover 12, the insulation sheet 51 is arranged on the upper cover 11, and the insulation sheet 51 is positioned between the display panel 31 and at least part of the air inlet holes 110, the insulation sheet 51 can not block the air inlet holes 110, and effective air inlet of the induction cooker is ensured.

In addition, since the display panel 31 is a charged member, if a person extends a strip-shaped or rod-shaped conductor from the air inlet hole 110 into the bottom case 1, the conductor touches the display panel 31 in the bottom case 1, which may cause unsafe accidents such as electric shock. In the electromagnetic oven of the embodiment, the insulation sheet 51 arranged on the upper cover is positioned between the display panel 31 and at least part of the air inlet holes 110, so that even if a conductor enters the bottom case 1 from the part of the air inlet holes 110, the conductor cannot easily touch the display panel 31 due to the existence of the insulation sheet 51, thereby reducing the probability of electric shock caused by the fact that the conductor extending from the air inlet holes 110 touches the display panel 31 in the bottom case 1 to a certain extent, and improving the safety.

Referring to fig. 1 and 2, in the present embodiment, the upper cover 11 is made of an insulating material, and an insulating sheet 51 is integrally formed with the upper cover 11. Therefore, when the upper cover 11 is manufactured, the insulating sheet 51 is directly formed on the upper cover 11, and on the basis of separating the display panel 31 from at least part of the air inlet holes 110, the electromagnetic oven is more convenient to mount, and the insulating sheet 51 and the upper cover 11 are more stable in integral structure.

Of course, in other embodiments, the insulating sheet 51 may be separately manufactured, that is, the insulating sheet 51 may be mounted on the upper cover 11 after being manufactured. For example, the insulating sheet 51 is fixed to the upper cover 11 by a screw or by a snap or adhesive. In this case, the material of the upper cover 11 is not limited. As long as the water vapor, dust, oil smoke and electric conductors entering from the air inlet 110 do not directly fall or easily touch the charged part in the bottom case 1.

The insulating sheet 51 may be a plastic sheet, such as a polyethylene terephthalate (PET), a mica sheet, or other materials with insulating properties and sufficient strength. The display panel 31 and at least part of the air inlet holes 110 are separated to a certain degree through a plastic sheet or a mica sheet, so that the effect is good and the manufacturing cost is low.

Specifically, the thickness of the insulating sheet 51 may be set between 0.01mm and 3 mm. If the insulation sheet 51 is too thick, the manufacturing cost is increased, the space occupied by the insulation sheet 51 is increased, and the volume of the bottom case 1 and the volume of the induction cooker are inevitably increased. By setting the thickness of the insulating sheet 51 within the above range, the manufacturing cost is reduced on the basis of ensuring effective separation of the display panel 31 and the air inlet 110, the required installation space of the insulating sheet 51 is reduced, and the bottom case 1 is not required to be too large.

In the present embodiment, the display panel 31 is fixed specifically to the insulating sheet 51. Therefore, the electromagnetic oven is more convenient to install. For example, the display panel 31 is fixed to the insulating sheet 51 by screws or is adhered to the insulating sheet 51. Of course, in other implementations, the display panel 31 may be fixed to the bottom of the panel or to the upper cover 11.

Further, at least a part of the edge of the insulating sheet 51 has a flange 50 extending upward, and the display panel 31 is located in an area surrounded by the flange 50. Because the edge of the insulation sheet 51 is provided with the flanging 50, the display panel 31 is positioned in the area enclosed by the flanging 50, so that water vapor, oil smoke, dust or electric conductors and the like entering from the air inlet holes 110 are less prone to falling or contacting the display panel 31; meanwhile, the turned-over edge 50 plays a certain limiting role, so that the display panel 31 is more convenient to mount. In addition, if soup on the panel of the induction cooker accidentally enters the bottom case 1 from the joint of the bottom case 1 and the panel or from the side wall of the bottom case 1 or the joint of the upper cover 11 and the lower cover 12, the flanging 50 can block the soup to a certain extent, so that the soup is not easy to flow onto the display panel 31, and the display panel 31 is effectively protected.

In a specific implementation, an insulating layer 52 may be further provided between the lower surface 311 of the display panel 31 and the insulating sheet 51. Through the combined action of the insulating sheet 51 and the insulating layer 52, the separation effect between the display panel 31 and at least part of the air inlet holes 110 is further improved, the probability of the situation that water vapor, oil smoke or dust and the like entering from the air inlet holes 110 directly fall on the display panel 31 is further reduced, the probability of the situation that the electric conductors extending from the air inlet holes 110 touch the display panel 31 in the bottom shell is further reduced, and the double-insulation effect is realized.

Preferably, the insulating layer 52 covers the entire lower surface of the display panel 31. Therefore, the whole lower surface 311 of the display panel 31 can be separated from the air inlet holes 110, the separation effect of the insulating layer 52 on the display panel 31 and the air inlet holes 110 is further improved, the probability that water vapor, oil smoke or dust and the like entering from the air inlet holes 110 directly fall on the display panel 31 is reduced to a greater extent, and the probability that the electric conductors extending from the air inlet holes 110 touch the display panel 31 is reduced to a greater extent.

In one possible implementation of the present embodiment, the insulating layer 52 is formed by spraying or printing an insulating material on the lower surface of the display panel 31 and/or the upper surface of the insulating sheet 51. The connection between the insulating layer 52 and the display panel 31 or the insulating sheet 51 is more firm by the above arrangement, the insulating layer 52 is not easy to fall off, and the manufacture is more convenient. The insulating material can be silicone paint or rubber paint or insulating grease or insulating ink.

For example, the insulating layer 52 is formed on the lower surface of the display panel 31 by printing insulating ink on the lower surface of the display panel 31, or the insulating layer 52 is formed on the upper surface of the insulating sheet 51 by printing insulating ink on the upper surface of the insulating sheet 51.

The insulating ink may be, for example, a uv curable ink having a high insulating property with a solid content of 100% and containing no solvent.

In another possible implementation of the present embodiment, the insulating layer 52 includes an insulating paper disposed between the lower surface 311 of the display panel 31 and the insulating sheet 51. The display panel 31 and the air inlet holes 110 are separated through the combined action of the insulating paper and the insulating sheet 51, the effect is good, and the manufacturing cost is low. In particular, the insulating paper may be adhered to the lower surface 311 of the display panel 31, which is convenient to install and reliable in connection. Of course, the insulating paper may be fixed to the lower surface 311 of the display panel 31 by other means such as suction.

In addition, it is also possible to spray or print an insulating material on the lower surface of the display panel 31, and then set an insulating paper, for example, spray a silicone paint on the lower surface of the display panel 31, and then paste a layer of insulating paper, that is, to achieve a double insulating effect.

When the air inlet hole is opened on the first side wall 121, because the first side wall 121 faces the user, the user can visually and conveniently see the air inlet hole 110, and easily see whether the air inlet hole 110 is blocked, so that the air inlet hole 110 can be cleaned in time, and the influence on air inlet is avoided. In addition, when the air inlet 110 is formed in the first side wall 121, the distance between the air inlet 110 and the table top is greater than the position of the bottom wall of the bottom case, so that the phenomenon that accumulated water on the table top is sucked into the bottom case when the induction cooker works can be avoided, the service life of the induction cooker is prolonged, and unsafe accidents are avoided. Moreover, since the first air storage area 101 is located between the partition 61 and the first side wall 121, and the insulation sheet 51 is located between the display panel 31 and at least a portion of the air inlet holes 110 of the first air storage area 101, when the first side wall 121 is a front side wall facing the user, that is, the display panel 31 is close to the front side of the induction cooker, that is, the display panel 31 is close to the cooker, which is convenient for the cooker to operate.

Alternatively, the second side wall 122 and the bottom wall are both provided with air inlet holes 110.

When the air inlet holes 110 of the second air storage area 102 are formed in the second side wall, the distance between the air inlet holes 110 and the table top is larger than the position of the bottom wall of the bottom case 1, so that the phenomenon that water accumulated on the table top is sucked into the bottom case 1 when the induction cooker works can be avoided, the service life of the induction cooker is prolonged, and unsafe accidents are avoided.

Preferably, the first wind storage area 101 and the second wind storage area 102 may be communicated. If one of the first air storage area 101 and the second air storage area 102 is accidentally blocked, cooling air enters from the other one of the first air storage area 101 and the second air storage area 102 and flows to the fan cavity of the heat dissipation fan 4, so that normal heat dissipation of the induction cooker is ensured.

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 realization, the wind-break muscle can with lower cover 12 integrated into one piece, for example, when lower cover 12 is the plastic lower cover, when lower cover 12 is being moulded plastics, at the integrative injection moulding wind-break muscle of lower cover 12. 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 this embodiment, the wind blocking rib specifically includes a first wind blocking rib 62 disposed between the first wind storage area 101 and the fan cavity of the heat dissipation fan 4, and a second wind blocking rib 63 disposed between the second wind storage area 102 and the fan cavity of the heat dissipation fan 4. The first air blocking rib 62 is provided with a first air vent 601, and the second air blocking rib 63 is provided with a second air vent 602. The cooling air entering the first air storage area 101 enters the fan cavity of the heat dissipation fan 4 through the first ventilation opening 601, and the cooling air entering the second air storage area 102 enters the fan cavity of the heat dissipation fan 4 through the second ventilation opening 602.

By providing the wind blocking rib, the cooling wind entering the fan cavity of the heat dissipation fan 4 can be prevented from blowing back to the wind storage area. Meanwhile, the first ventilation opening 601 and the second ventilation opening 602 are arranged on the wind blocking rib, so that the cooling air in the first air storage area 101 can smoothly enter the heat dissipation fan 4 through the first ventilation opening 601, and the cooling air in the second air storage area 102 can smoothly enter the heat dissipation fan 4 through the second ventilation opening 602, thereby ensuring the air quantity blowing to the heating element, effectively utilizing the cooling air and further improving the heat dissipation effect.

Preferably, a first ventilation opening 601 is formed between the first wind blocking rib 62 and the inner bottom wall of the bottom case 1, and a second ventilation opening 602 is formed between the second wind blocking rib 63 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, and the speed and the smoothness of the wind inlet are further improved.

The top end of the first vent 601 may or may not extend to the top of the first wind-shielding rib 62. The top end of the second ventilation opening 602 may extend to the top of the second wind blocking rib 63, or may not extend to the top of the second wind blocking rib 63. Preferably, the plane on which the top ends of the first ventilation opening 601 and the second ventilation opening 602 are located is not 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 ventilation opening 601 and the top end of the second ventilation opening 602 are located is not higher than the lowest position of the air inlet surface of the heat dissipation fan. If the plane on which the top end of the vent is located is set to be higher than the plane on which the lower surface of the heat dissipation fan 4 is located, the heat dissipation fan 4 may blow part of the wind back into the wind storage area, and then the part of the wind cannot blow the heating elements such as the coil panel 2 and the main control board 32, and the amount of wind blowing the heating elements is reduced.

In other embodiments, only the first wind-blocking rib 62 or only the second wind-blocking rib 63 may be provided. Or, the wind blocking rib is not arranged, at this time, the first wind storage area 101 is directly communicated with the fan cavity of the heat dissipation fan 4, and the second wind storage area 102 is directly communicated with the fan cavity of the heat dissipation fan 4.

During the concrete implementation, the air inlet 110 can set up to a plurality of, and a plurality of air inlet 110 intervals are arranged on the drain pan 1, for example, a plurality of air inlet 110 arrange into the grid form, have not only guaranteed intake and air inlet homogeneity, and have improved the outward appearance aesthetic feeling of electromagnetism stove. The plurality of air inlet holes 110 may also be arranged in a plurality of rows and columns or in a ring shape. Each air inlet hole 110 may be in the shape of a bar, 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 spaced apart from each other on the side wall of the bottom case 1 opposite to the side wall provided with the air inlet hole 110, for example, the air outlet holes 120 are spaced apart from each other along the length direction of the side wall to form a grid, and/or the air outlet holes 120 are spaced apart from each other on the bottom wall of the bottom case 1 away from the air inlet hole 110, for example, the air outlet holes 120 are radially disposed.

Referring to fig. 5, the coil panel 2, the main control board 32 and the heat dissipation fan 4 may be arranged in a triangle shape as a whole. Thus, a part of the air discharged by the heat dissipation fan 4 is blown to the coil panel 2, and a part of the air is blown to the main control board 32, and then the hot air is directly blown out from the air outlet 120 of the bottom case 1.
