These problems seriously affect the service life of the induction cooker. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Compared with the prior art, the utility model is an induction cooker with an upper air duct cooling structure, in which independent first and second cooling channels are arranged for the coil disk and the control circuit board in the shell, and a heat dissipation fan is arranged in the first cooling channel, so that the heat of the coil disk and the control circuit board can be discharged respectively by utilizing the first cooling channel and the second cooling channel, thereby effectively solving the problem of damage to various components in the shell due to excessive or excessive temperature rise due to high power, and effectively extending the service life of the equipment. Secondly, the utility model increases the heat dissipation effect of the whole machine without changing the size of the whole machine. In addition, the first air duct component divides the inner cavity of the shell into two upper and lower cooling channels, thereby preventing the heat in the upper cooling channel from entering the lower cooling channel and affecting the heat dissipation efficiency.

[0007] Furthermore, one end of the second air duct component close to the air inlet is spaced apart from the inner side of the shell to form an air avoidance zone; the air inlet connects the air avoidance zone with the outside world; one side of the first air duct component opposite to the air avoidance zone is recessed to form a first installation area, and the side of the first air duct component opposite to the air avoidance zone is a coil installation area, the first cooling fan is arranged in the first installation area, and the coil disk is arranged in the coil installation area.

[0008] The first air duct component adopts the above-mentioned arrangement, thereby fully utilizing the internal space of the shell to install the first heat dissipation fan, making the components in the shell more compact, while ensuring that the first heat dissipation fan can take in air independently.

[0009] Furthermore, the first installation area is configured such that the outer end thereof is inclined toward the bottom of the air avoidance area.

[0010] This arrangement makes the first cooling fan tilted relative to the coil installation area, so that the airflow sent by the first cooling fan hits the inside of the panel upward and is dispersed to the entire coil installation area, thereby increasing the gas flow speed of the entire coil installation area and improving the heat dissipation effect.

[0013] Furthermore, one end of the upper base plate toward the air outlet is tilted downward and is located above the lowest point of the air outlet.

[0014] The above arrangement can increase the contact area of ​​the first cooling channel connected to the outside world, thereby increasing the heat dissipation range and improving the heat dissipation speed.

[0018] The second air duct component adopts the above-mentioned arrangement method to enable the airflow output by the second heat dissipation fan to flow to the circuit board installation in a concentrated manner, thereby ensuring the heat dissipation effect.

[0019] Furthermore, an air guide portion is provided between the second installation area and the circuit board installation area and is inclined upward from the second installation area to connect to the circuit board installation area.

[0020] The provision of the air guide portion can narrow the airflow, so that the airflow output by the second heat dissipation fan flows more concentratedly toward the circuit board installation area, thereby increasing the airflow speed in the circuit board installation area and improving the heat dissipation effect.

[0021] Furthermore, the first heat dissipation fan is a vortex fan; the first air duct component is provided with a first opening connected to the second cooling channel, and the first heat dissipation fan is arranged on the first opening.

[0022] Since the first cooling fan is located above the second cooling fan and is a vortex fan, the first cooling fan can stably inhale air entering the shell through the air inlet, thereby avoiding interference of airflow entering the first cooling channel and the second cooling channel.

[0023] Furthermore, the operating element is arranged on a side of the panel facing the first air duct component; and a blocking wall is arranged on the outside of the operating element on the first air duct component.

[0024] The setting of the baffle wall can block the heat generated by the coil disk outside the operating element, thereby preventing the heat generated by the coil disk from affecting the normal use of the operating element. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] One end of the second air duct component 14 close to the second heat dissipation fan 22 / air inlet 25 is spaced apart from the inner side of the shell 3 to form an air avoidance area 27; the air inlet 25 connects the air avoidance area 27 with the outside world; one side of the first air duct component 6 facing the air avoidance area 27 is recessed to form a first installation area 7, and the side of the first air duct component 6 opposite to the air avoidance area 27 is a coil installation area 8, the first heat dissipation fan 13 is arranged in the first installation area 7, and the coil disk 4 is arranged in the coil installation area 8.

[0037] The first air duct component 6 adopts the above-mentioned setting method, so as to fully utilize the internal space of the shell 3 to install the first cooling fan 13 and the second cooling fan 22, making the design of the components in the shell 3 more compact, while ensuring that the first cooling fan 13 and the second cooling fan 22 have independent air intake.

[0038] The first installation area 7 is arranged so that the outer end thereof is inclined toward the bottom of the clearance area 27 .
