[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] See also Figure 1-Figure 4The induction cooker comprises a base 1, a fan 2 and a coil disk 3. The base 1 is installed and connected with the fan 2. The base 1 has a first installation cavity 11 for installing the coil disk 3. The air outlet ends of the fan 2 are respectively communicated with the first installation cavity 11. A front wind shield 41 and a rear wind shield 42 are arranged in the first installation cavity 11. The front wind shield 41 and the rear wind shield 42 are arranged from near to far relative to the fan 2. The front wind shield 41 and the rear wind shield 42 are respectively formed on one side of the air outlet end of the fan 2 to guide the fan 2. The front heat dissipation duct 411 and the rear heat dissipation duct 421 guide the air flow to move in the forward and reverse directions. The front heat dissipation duct 411 intersects with at least part of the rear heat dissipation duct 421 in the forward extension direction. After the airflow enters the first installation cavity 11 from the air outlet end of the fan 2, part of the airflow first passes through the front heat dissipation duct 411 and then enters the rear heat dissipation duct 421, and part of the airflow moves in the reverse direction under the action of the rear heat dissipation duct 421. After the two airflows meet, a vortex can be formed and diffused in the first installation cavity 11.
[0023] The front heat dissipation duct 411 and the rear heat dissipation duct 421 cooperate to enable the airflow generated by the fan 2 to form a vortex in the first installation cavity 11. Compared with the method in which the fan 2 blows air directly to the coil disk 3, the airflow can act on the coil disk 3 more evenly, and the heat dissipation effect at different positions on the coil disk 3 is more uniform.
[0024] Furthermore, an external heat dissipation duct 422 capable of guiding the airflow to move in the opposite direction is formed between the side of the rear wind shield 42 facing away from the fan 2 and the inner wall of the first installation cavity 11, thereby further diffusing the airflow generated by the fan 2 toward the outside of the first installation cavity 11, and making the airflow distribution at different positions in the first installation cavity 11 more uniform.
[0025] Furthermore, the base 1 also has a second installation cavity 12, to which a circuit board (not shown) is connected. The air outlet of the fan 2 is connected to the second installation cavity 12, so that the airflow generated by the fan 2 can also be used to cool the circuit board, thereby extending the service life of the circuit board.
[0026] Furthermore, exhaust holes 13 are provided on the base 1 at positions corresponding to the outsides of the first installation cavity 11 and the second installation cavity 12 , and airflow can discharge the heat in the first installation cavity 11 and the second installation cavity 12 to the outside through the exhaust holes 13 .
[0027] Furthermore, the base 1 is connected with a heat shield 5 at a position above the second installation cavity 12, and the heat shield 5 can reduce the influence of the heat generated by the coil disk 3 on the circuit board. The heat shield 5 is detachably connected to the base 1, which is convenient for users to inspect and maintain the circuit board.
[0028] Furthermore, the outer side of the heat insulation cover 5 is adjacent to and matched with the periphery of at least part of the coil disk 3 , so that the structure between the heat insulation cover 5 and the coil disk 3 is more compact, thereby improving the space utilization rate in the base 1 .
[0029] Furthermore, a plurality of mounting ears 31 are distributed on the outer side of the coil disk 3 . The mounting ears 31 can be connected and fixed to the base 1 by means of screws. The coil disk 3 can be mounted and fixed to the base 1 through the mounting ears 31 .
[0030] The heat shield 5 is provided with a positioning recess 51 corresponding to the mounting ear 31. The positioning recess 51 is sleeved on the horizontal outer side of the mounting ear 31. The mounting ear 31 cooperates with the positioning recess 51 to prevent the heat shield 5 from being fooled, thereby making the installation efficiency of the heat shield 5 higher.
[0031] Furthermore, the base 1 has an air inlet channel 14, which is connected to the air inlet end of the fan 2. The projection of the air inlet channel 14 in the horizontal direction coincides with the fan 2 and the first installation cavity 11. The length of the air inlet channel 14 is relatively long, so that more external airflow can enter the fan 2 through the air inlet channel 14.
[0032] A partition plate 6 is provided between the air inlet passage 14 and the first installation cavity 11 , and the partition plate 6 can prevent the air inlet passage 14 from interfering with the air flow in the first installation cavity 11 , thereby ensuring that the air flow flows along a preset path.
[0033] Furthermore, the base 1 is provided with a plurality of air inlet holes 15 , which are distributed along the length direction of the air inlet channel 14 to ensure that sufficient air flows into the air inlet channel 14 through the air inlet holes 15 .
[0034] The above embodiments are only preferred embodiments of the present invention, and the present invention may have other embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all within the scope set by the claims of this application.
