Description

Technical Field

[0001] The invention relates to an electromagnetic cooker, in particular to an electromagnetic cooker with intuitive firepower. Background Art

[0002] An induction cooker is an electrical cooking appliance made based on the principle of electromagnetic induction heating. It mainly uses a coil disk to generate a low-frequency (20-25KHZ) alternating magnetic field under the action of a control circuit, which generates a large number of dense eddy currents through a magnetically conductive (iron) pot, and converts the induced current into heat to heat food. In recent years, in order to improve the convenience of users in using induction cookers, various types of induction cookers have appeared on the market, such as induction cookers with intuitive and visual firepower structures.

[0003] At present, patent (CN106376118A) discloses an induction cooker with intuitive firepower, specifically including (such as Figure 1 and Figure 2 As shown): a bottom shell 10 and a panel 20 covered on the bottom shell 10, the panel 20 includes a fire viewing area 21, and a fire viewing box 40, a light-emitting assembly 30 and a fan assembly 71 are also arranged in the bottom shell 10. The fire viewing box 40 is located between the lamp board and the coil disk. The light-emitting assembly 30 includes a plurality of light-emitting bodies 31, each of which includes a light-emitting end 311 and a power-on end 312. At least a portion of the light-emitting end 311 is located in the fire viewing box 40 (the light-emitting end specifically penetrates into the fire viewing box 40 through the lamp hole 41), and at least a portion of the power-on end 312 is located outside the fire viewing box 40. Specifically, the light-emitting body 311 is located in the fire viewing box 40. The optical component 30 also includes a mounting plate 32, on which a power-on end 312 is arranged. The mounting plate 32 is mounted on the outer wall of the fire visualization box 40, and the mounting plate 32 may be a circuit board. The mounting plate 32 is connected to a power source, so that the light-emitting body 31 is connected to the power source. When the mounting plate 32 is mounted on the outer wall of the fire visualization box 40 facing the lamp board, since the power-on end 312 on the mounting plate 32 and the lamp board adjacent to the mounting plate 32 are both charged bodies, a certain distance needs to be spaced between the fire visualization box 40 and the lamp board to avoid a short circuit between the lamp board and the mounting plate 32.

[0004] However, since the space in the induction cooker is limited, when the firepower visual box 40 is spaced a certain distance from the light board, the space in the induction cooker cannot be fully utilized, resulting in a waste of space in the induction cooker. Summary of the invention

[0005] In order to solve at least one of the problems mentioned in the background art regarding the waste of space in an induction cooker, the present invention provides an induction cooker that saves space and does not cause short circuit.

[0006] The present invention provides an induction cooker, comprising a bottom shell and a panel provided on the bottom shell and having a firepower visual area, wherein a firepower visual box corresponding to the firepower visual area is provided in the bottom shell, and the firepower visual box is used to project light to the firepower visual area, and further comprising:

[0007] An insulating spacer and a light bar with multiple light-emitting parts, wherein the light bar is arranged on the outer wall of the fire visualization box and the side of the light bar with the light-emitting parts faces the side wall of the fire visualization box, and the insulating spacer covers the other side of the light bar facing away from the outer wall.

[0008] The light bar comprises an insulating spacer and a plurality of light-emitting parts, and the light bar is arranged on the outer wall of the fire visualization box and the side of the light bar provided with the light-emitting parts faces the side wall of the fire visualization box, and the insulating spacer covers the other side of the light bar facing away from the outer wall, the insulating spacer separates the light bar from other charged bodies and plays an insulating role, thereby preventing the light bar from contacting with other charged bodies and causing a short circuit failure. In this way, when the fire visualization box is arranged between the light board and the coil disk, there is no need to have a certain distance between the light bar and the light board due to the blocking effect of the insulating spacer, and the interval between the fire visualization box and the light board can be reduced or even set without an interval. Compared with the prior art in which a certain distance is required between the fire visualization box and the light board, the present invention greatly saves the use space in the induction cooker and at the same time eliminates the possibility of a short circuit between the light bar and the light board. Therefore, the induction cooker provided in this embodiment saves the use space in the induction cooker and at the same time does not have a short circuit failure between the light bar and the light board during use, and is safer to use.

[0009] Optionally, the insulating spacer includes a fixed end and a free end, wherein the fixed end of the insulating spacer is connected to the firepower visual box, and the free end of the insulating spacer is folded around the fixed end so that the insulating spacer completely covers the light bar. In this way, it is easier to cover the light bar with the insulating spacer during the assembly process.

[0010] Optionally, the insulating spacer is integrally formed with the firepower visualization box, and the thickness of the fixed end of the insulating spacer is smaller than the thickness of the free end.

[0011] In this way, the insulating spacer is prevented from being connected to the firepower visualization box through an additional connecting piece, and at the same time, the thickness of the fixed end is smaller than the thickness of the free end, so that the insulating spacer is easier to fold.

[0012] Optionally, notches are provided on both sides of the fixed end.

[0013] In this way, the insulating spacer is more flexible and labor-saving when folding.

[0014] Optionally, a plurality of lamp holes corresponding to the light-emitting components are provided on the side walls of the firepower visualization box, and the lamp holes are used to emit the light emitted by the light-emitting components into the firepower visualization box.

[0015] Optionally, the side wall of the firepower visualization box corresponding to the light bar is a light-transmitting side wall.

[0016] Optionally, the light bar is fixed to the outer wall of the firepower visualization box by screws or buckles.

[0017] Optionally, the insulating spacer is fixed to the outer wall of the firepower visualization box by bonding, snapping or screws.

[0018] Optionally, the insulating spacer is an insulating plate made of polypropylene (PP) material.

[0019] Optionally, the light-emitting element is a light-emitting diode (LED).

Figure 7 It is a three-dimensional structural schematic diagram of the firepower visual box in the induction cooker of the present invention, Figure 8 Schematic diagram of the side structure of the firepower visual box in the induction cooker of the present invention. Figure 3-8 As shown, the induction cooker includes: a bottom shell 10 and a panel 20 covering the bottom shell 10, wherein the panel 50 includes a heating area, an operation area and a firepower viewing area 51, wherein the firepower viewing area 51 can be located between the heating area and the operation area, and a firepower viewing box 30 corresponding to the firepower viewing area 51 is provided in the bottom shell 10, and the firepower viewing box 30 is used to project light to the firepower viewing area 51 to form a flame shape. Specifically, a reflective component is provided in the firepower viewing box 30, and the light is projected to the firepower viewing area 51 through reflection of the reflective component, so that the user can observe the firepower size of the induction cooker through the firepower viewing area 51 during use, wherein, as shown in FIG. Figure 3 As shown, the bottom shell is also provided with a coil disk 20, a lamp board 40, a fan and a control board, which are commonly used components of an induction cooker. The specific structure and working principle can refer to the structure of an existing induction cooker.

[0045] Among them, Figure 3 As shown, when the fire visualization box 30 is arranged between the light board 40 and the coil disk 20, in order to avoid the problem of space waste in the induction cooker caused by a certain distance between the fire visualization box 30 and the light board 40, in this embodiment, it also includes: an insulating isolation member 31 and a light bar 32 provided with a plurality of light-emitting members (not shown), wherein the light bar 32 is arranged on the outer side wall 301 of the fire visualization box 30, specifically, the light bar 32 is arranged on the outer side wall 301 of the fire visualization box 30 facing the light board 40, and the light bar 32 has a side of the light-emitting member facing the side wall of the fire visualization box 30, that is, the light-emitting member faces the side wall of the fire visualization box 30, in this embodiment, the light-emitting member is used to generate light , and the light emitted by the light-emitting component can be projected into the fire visualization box 30, and the fire visualization box 30 projects the light onto the fire visualization area 51 to form a flame shape, wherein the insulating isolation member 31 covers the other side of the light bar 32 facing away from the outer wall 301, that is, one side of the light bar 32 faces the outer wall 301, and the other side of the light bar 32 faces away from the outer wall 301, and the insulating isolation member 31 covers the side of the light bar 32 facing away from the outer wall 301, wherein it should be noted that when the insulating isolation member 31 covers the side of the light bar 32 facing away from the outer wall 301, the insulating isolation member 31 completely covers one side of the light bar 32, that is, the light bar 32 is completely blocked by the insulating isolation member 31.

[0046] In the present embodiment, since the back side of the light bar 32 is covered with an insulating spacer 31, the insulating spacer 31 separates the light bar 32 from other charged bodies and acts as an insulator, thereby preventing the light bar 32 from contacting other charged bodies and causing a short circuit. In this way, when the fire visualization box 30 is arranged between the light board 40 and the coil disk 20, due to the blocking effect of the insulating spacer 31 between the light bar 32 and the light board 40, there is no need to maintain a certain distance between the fire visualization box 30 and the light board 40, and the gap between the fire visualization box 30 and the light board 40 can be reduced or even set without a gap. Therefore, compared with the prior art in which a certain distance is required between the fire visualization box 30 and the light board 40, in the present embodiment, the gap between the fire visualization box 30 and the light board 40 can be reduced or even eliminated by setting the insulating spacer 31, which greatly saves the use space in the induction cooker and at the same time eliminates the possibility of a short circuit between the light bar 32 and the light board 40.

[0047] In this embodiment, the light bar 32 can be a metal heat sink or a printed circuit board (PCB), and multiple light-emitting components can be connected in parallel or in series on the metal heat sink. In this embodiment, the light-emitting components can be light-emitting diodes (LED). When the light bar 32 is set on the outer wall 301 of the fire visualization box 30, the light bar 32 can be fixed on the outer wall 301 of the fire visualization box 30 by screws or snaps.

[0048] In this embodiment, the insulating isolation member 31 can specifically be an insulating plate, for example, an insulating plate made of polypropylene (PP for short), or other insulating materials, such as insulating tape. When the insulating isolation member 31 is an insulating tape, the insulating tape is directly adhered to the back of the light bar 32, or the insulating isolation member 31 is covered on the light bar 32 and fixed to the outer wall 301 of the fire visualization box 30 by screws, snaps or adhesives. When the insulating isolation member 31 is fixed to the outer wall 301 of the fire visualization box 30, since the light bar 32 is between the insulating isolation member 31 and the outer wall 301 of the fire visualization box 30, the insulating isolation member 31 is fixed while the light bar 32 is fixed.

[0049] Among them, in this embodiment, when the light bar 32 is set on the outer wall 301 of the fire visualization box 30, in order to emit the light emitted by the light-emitting part on the light bar 32 into the fire visualization box 30, in this embodiment, specifically, a plurality of lamp holes 302 corresponding to the light-emitting parts can be opened on the side wall of the fire visualization box 30, and the lamp holes 302 are used to emit the light emitted by the light-emitting parts into the fire visualization box 30. When setting, first align the light-emitting part on the light bar 32 with the lamp hole 302 or extend one end of the light-emitting part into the lamp hole 302, and then fix the light bar 32.

[0050] Alternatively, the side wall of the fire visualization box 30 corresponding to the light bar 32 can also be set as a translucent side wall. In this way, when the light bar 32 is set with one side of the light-emitting component facing the translucent side wall, the light emitted by the light-emitting component passes through the side wall into the fire visualization box 30. When the light enters the fire visualization box 30, it is reflected by the reflective component in the fire visualization box 30 and projected onto the fire visualization area 51 to form a flame shape.

[0051] In order to facilitate covering the insulating spacer 31 on the light bar 32, in this embodiment, Figure 7-8 As shown, the insulating spacer 31 includes a fixed end 312 and a free end 311, wherein the fixed end 312 of the insulating spacer 31 is connected to the firepower visualization box 30, as shown in FIG. Figure 8As shown, the fixed end 312 of the insulating spacer 31 is specifically connected to the top of the outer wall 301 of the firepower visual box 30 where the light bar 32 is set. At the same time, the free end 311 of the insulating spacer 31 is folded around the fixed end 312, that is, the insulating spacer 31 can be folded up and down on the firepower visual box 30. When the light bar 32 needs to be covered, Figure 5-6 As shown, the insulating isolation piece 31 is folded downward and completely covers the light bar 32. When the light bar 32 needs to be exposed, the insulating isolation piece 31 is folded upward. In order to achieve the purpose of the insulating isolation piece 31 completely covering the light bar 32, the width of the insulating isolation piece 31 is greater than the width of the light bar 32, and the free end 311 of the insulating isolation piece 31 can completely cover the bottom end of the light bar 32.

[0052] In this embodiment, when the insulating spacer 31 is folded downward to cover the light bar 32, in order to fix the insulating spacer 31, Figure 7 As shown, a screw hole 314 can be provided on the insulating isolation piece 31, and a corresponding screw hole 303 can be provided on the outer wall 301. The insulating isolation piece 31 is fixed to the outer wall 301 by passing the screws through the screw holes 314 and the screw holes 303. When the screws pass through the screw holes 314 and the screw holes 303 to fix the insulating isolation piece 31 to the outer wall 301, a screw hole 321 corresponding to the screw hole 314 and the screw hole 303 can be also provided on the light bar 32. In this way, the screws pass through the screw holes 314, the screw holes 321 and the screw holes 303 in sequence to fix both the insulating isolation piece 31 and the light bar 32 to the outer wall 301 of the firepower visualization box 30.

[0053] Among them, in this embodiment, when the fixed end 312 of the insulating isolation piece 31 is connected to the fire visualization box 30, the fixed end 312 can be connected to the fire visualization box 30 by a hinge, so that the free end 311 of the insulating isolation piece 31 can be folded around the fixed end 312, or an axis can be provided on the outer wall 301 of the fire visualization box 30, and the fixed end 312 of the insulating isolation piece 31 is sleeved on the axis, and the free end 311 of the insulating isolation piece 31 is folded around the axis. The specific implementation method can be set according to the actual application and is not limited in this embodiment.

[0054] Among them, in order to facilitate assembly and avoid using additional connectors to connect the fixed end 312 of the insulating spacer 31 to the fire visualization box 30, in this embodiment, the insulating spacer 31 and the fire visualization box 30 are integrally formed, that is, the manufacturing of the insulating spacer 31 is completed at the same time during the manufacturing process of the fire visualization box 30, and the insulating spacer 31 and the fire visualization box 30 are a whole, and in order to realize that the free end 311 of the insulating spacer 31 can be folded around the fixed end 312, specifically as shown in FIG. Figure 8As shown, the thickness of the fixed end 312 of the insulating spacer 31 is set to be smaller than the thickness of the free end 311, that is, the fixed end 312 of the insulating spacer 31 is a thin-walled area, which makes the insulating spacer 31 easier to bend.

[0055] In order to further facilitate the folding of the insulating spacer 31, in this embodiment, Figure 7 As shown, notches 313 are provided on both sides of the fixed end 312, so that the connection area between the fixed end 312 and the firepower visualization box 30 is reduced, thereby making the folding of the insulating isolation piece 31 more flexible.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
