Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic cookers, and particularly relates to a heat dissipation type electromagnetic cooker. Background Art

[0002] An electromagnetic cooker is an electric cooking appliance made according to the principle of electromagnetic induction heating. It mainly uses a coil disk to generate an alternating magnetic field with a low frequency (20 - 25KHZ) under the action of a control circuit. A large number of dense eddy currents are generated through a ferromagnetic (iron) cookware, and the induced current is converted into heat to heat food.

[0003] The existing electromagnetic cookers generally include a housing, a coil disk assembly, a heat dissipation assembly, a circuit board, a display control panel, a glass plate, etc. Various electronic components are arranged on the circuit board, and copper foil traces for electrically connecting various electronic components are arranged on the bottom surface of the circuit board. The electromagnetic cooker generally uses a fan as the heat dissipation assembly. An air inlet is arranged at the bottom of the housing, and some air outlets are arranged on the side surface of the housing. When the electromagnetic cooker works, air enters through the air inlet, and the fan blades on the fan drive the air to be discharged from the air outlets to dissipate heat from the coil disk assembly, the circuit board, etc.

[0004] For a conventional electromagnetic cooker, air outlets are usually arranged on multiple side surfaces of the housing. When the fan works, some airflows do not pass through the coil disk assembly and the circuit board and directly flow out from the air outlets, resulting in poor heat dissipation effect of the electromagnetic cooker. On the other hand, before the electromagnetic cooker leaves the factory, a light penetration test needs to be carried out. Through a light simulation needle puncture test, this test requires that light cannot directly penetrate through the through holes into the electromagnetic cooker. However, for the housing of a conventional electromagnetic cooker, its air inlet and air outlets cannot meet the requirements of this test.

[0005] Therefore, the prior art still needs to be improved and developed. Summary of the Utility Model

[0006] In view of the deficiencies of the above-mentioned prior art, the purpose of the utility model is to provide a heat dissipation type electromagnetic cooker to solve the problems of poor heat dissipation effect of the electromagnetic cooker in the prior art and the inability to pass the simulated needle puncture test.

[0007] A heat dissipation type electromagnetic cooker, comprising a housing and a coil assembly. A first chamber and a second chamber which are communicated with each other are arranged inside the housing. A first through hole and a second through hole which are communicated with the first chamber are respectively arranged on the left and right sides of the housing. A first deflector is arranged on the right side of the first through hole, and a second deflector is arranged on the left side of the second through hole. An air channel is formed between the first deflector and the second deflector. The coil assembly is located in the air channel. The air flow in the first chamber flows along the air channel and then is discharged through the first through hole and the second through hole. A fan is arranged in the second chamber. A third through hole which communicates with the second chamber is arranged below the fan. A protective cover is fixed below the third through hole. At least one side of the protective cover is provided with a plurality of fourth through holes which communicate with the third through hole.

[0008] Specifically, both the first deflector and the second deflector are of arc-shaped structures.

[0009] Specifically, a partition board is arranged inside the housing. The partition board is located between the first chamber and the second chamber. A fifth through hole which communicates with the first chamber and the second chamber is arranged in the middle of the partition board.

[0010] Specifically, the protective cover is fixed to the bottom of the housing by screws.

[0011] Specifically, adjustable feet are arranged at the four corner positions of the bottom of the housing.

[0012] Specifically, a first inclined surface which bends towards the first chamber is arranged at the lower end of the left side of the housing. The first through hole is arranged on the first inclined surface; a second inclined surface which bends towards the first chamber is arranged at the lower end of the right side of the housing. The second through hole is arranged on the second inclined surface.

[0013] Specifically, the heat dissipation type electromagnetic cooker further comprises a display control panel which is installed on the upper end of the housing by buckles.

[0014] The beneficial effects of the utility model:

[0015] The heat-dissipating induction cooker of the present utility model is provided with a first flow guide plate on the right side of the first through hole and a second flow guide plate on the left side of the second through hole. An air channel is formed between the first flow guide plate and the second flow guide plate, and the coil assembly is arranged in the air channel. When the fan is started, the fan blades drive the air to enter the protective cover from the fourth through hole, then enter the second chamber along the third through hole, and then enter the first chamber. The air flow in the first chamber flows along the air channel, and the air flow takes away the heat generated when the coil assembly works, and then is discharged through the first through hole and the second through hole, having a good heat dissipation effect; moreover, by using the blocking effect of the first flow guide plate on the left side and the blocking effect of the second flow guide plate on the right side, the light of the simulated needle puncture test can be prevented from entering the inside of the first chamber. Through the protective cover arranged below the third through hole, the light of the simulated needle puncture test can be prevented from entering the second chamber vertically, enabling it to pass the simulated needle puncture test, improving the protection effect of the induction cooker, and preventing the parts inside the induction cooker from being damaged due to foreign objects directly passing through these through holes and entering the inside of the induction cooker.

[0025] As Figures 1 to 6 , this embodiment discloses a heat-dissipating induction cooker, which includes a housing 10 and a coil assembly 20. A first chamber 11 and a second chamber 12 that communicate with each other are provided inside the housing 10. A first through hole 13 and a second through hole 14 that communicate with the first chamber 11 are respectively provided on the left and right sides of the housing 10. A first deflector 15 is provided on the right side of the first through hole 13, and a second deflector 16 is provided on the left side of the second through hole 14. An air passage 17 is formed between the first deflector 15 and the second deflector 16. The coil assembly 20 is located in the air passage 17. The air flow in the first chamber 11 flows along the air passage 17 and then is discharged through the first through hole 13 and the second through hole 14. A fan 30 is provided in the second chamber 12. A third through hole 18 that communicates with the second chamber 12 is provided below the fan 30. A protective cover 40 is fixed below the third through hole 18. At least one side of the protective cover 40 is provided with a plurality of fourth through holes 41 that communicate with the third through hole 18.

[0026] For the heat-dissipating induction cooker of this embodiment, a first deflector 15 is provided on the right side of the first through hole 13, and a second deflector 16 is provided on the left side of the second through hole 14. An air passage 17 is formed between the first deflector 15 and the second deflector 16. The coil assembly 20 is arranged in the air passage 17. When the fan 30 is started, the fan blades drive the air to enter the protective cover 40 from the fourth through holes 41, then enter the second chamber 12 along the third through hole 18, and then enter the first chamber 11. The air flow in the first chamber 11 flows along the air passage 17, and the air flow takes away the heat generated when the coil assembly 20 works, and then is discharged through the first through hole 13 and the second through hole 14, having a good heat dissipation effect.

[0027] In addition, by providing a first flow guide plate 15 on the right side of the first through hole 13, the blocking effect of the first flow guide plate 15 on the left side can be utilized to prevent the light from the simulated needle puncture test from entering the interior of the first chamber 11. A second flow guide plate 16 is provided on the left side of the second through hole 14, and by using the blocking effect of the second flow guide plate 16 on the right side, the light from the simulated needle puncture test can be prevented from entering the interior of the first chamber 11. By providing a protective cover 40 below the third through hole 18, the light from the simulated needle puncture test can be prevented from entering the second chamber 12 vertically, enabling it to pass the simulated needle puncture test, improving the protection effect of the induction cooker, and preventing the internal parts of the induction cooker from being damaged due to foreign objects directly passing through these through holes and entering the interior of the induction cooker.

[0028] Please refer to Figure 1 and Figure 3 , the first flow guide plate 15 and the second flow guide plate 16 in this embodiment are both arc-shaped structures. One end of the first flow guide plate 15 away from the second flow guide plate 16 is connected to the inner wall of the housing 10, and one end of the second flow guide plate 16 away from the first flow guide plate 15 is connected to the inner wall of the housing 10, so that the connection position cannot pass air flow, thereby better guiding the air flow to flow only along the air channel 17 formed between the first flow guide plate 15 and the second flow guide plate 16, thus improving the heat dissipation effect of the coil assembly 20. The design of the arc-shaped structure can reduce the air flow resistance and improve the stability of the first flow guide plate 15 and the second flow guide plate 16.

[0029] Please refer to Figure 3 , a partition plate 19 is provided inside the housing 10. The partition plate 19 is located between the first chamber 11 and the second chamber 12, and a fifth through hole 191 communicating the first chamber 11 and the second chamber 12 is provided in the middle of the partition plate 19.

[0030] Please refer to Figure 4 and Figure 5 , the protective cover 40 in this embodiment is fixed to the bottom of the housing 10 by screws (not shown), and the detachable connection is achieved through the screws, which is convenient for disassembly, cleaning or maintenance.

[0031] Please refer to Figure 4 , adjustable-height feet 50 are provided at the four corner positions of the bottom of the housing 10 in this embodiment. The feet 50 include an upper fixing member fixed to the bottom of the housing 10 by welding and a lower adjusting member threadedly connected to the upper fixing member. Specifically, a screw hole is provided at the lower end of the upper fixing member, and a stud is connected to the upper end of the lower adjusting member. The height adjustment is achieved through the threaded cooperation of the screw hole and the stud. Moreover, for some application scenarios, the placement tabletop may be uneven, and by adjusting the height of one or more feet 50, the induction cooker can also be placed horizontally.

[0032] Please refer to Figure 2 and Figure 3, in practical applications, due to improper user operation or other reasons, water or oil is likely to spill on the glass panel of the induction cooker. In the conventional square shell structure, water or oil is likely to enter the induction cooker through the heat dissipation holes of the square shell, resulting in problems such as short circuits. For this reason, in this embodiment, a first inclined surface 110 bent toward the first chamber 11 is provided at the lower left end of the shell 10, and a first through hole 13 is provided on the first inclined surface 110; a second inclined surface 111 bent toward the first chamber 11 is provided at the lower right end of the shell 10, and a second through hole 14 is provided on the second inclined surface 111. By providing the first inclined surface 110 and the second inclined surface 111, water or oil on the glass panel of the induction cooker will directly drip from the upper ends of the left and right sides of the shell 10, which can well prevent water or oil from entering the first chamber 11 through the first through hole 13 or the second through hole 14.

[0033] Please refer to Figure 3 , the heat dissipation type induction cooker further includes a display control panel 60. The display control panel 60 is installed on the upper end of the shell 10 through a buckle 70. The display control panel 60 is provided with indicator lights and touch springs. A glass panel is also provided on the top of the shell 10. The glass panel is provided with a plurality of touch control areas. The upper end surface of the touch spring abuts against the touch control area at the corresponding position. The touch spring is a switch element commonly used in induction cookers. When the user gently touches the touch control area of the glass panel, the touch spring is responsible for connecting or disconnecting the power supply circuit of the induction cooker to realize functions such as turning on, turning off, and adjusting the temperature; the indicator lights cooperate with the printed characters or patterns on the glass panel, and by lighting up and turning off, the touch control operation of the user is made more intuitive.

[0034] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of the present invention.
