The pressure cooker comprises a cooker body and a cooker cover covering the cooker body, as shown in fig. 1, the cooker body comprises a water collecting ring, a base 10, an electromagnetic wire coil 20, a heat preservation cover 30, an inner container 40 and a power panel box 50, a power panel 300 is fixed on the power panel box 50, the power panel 300 is connected with the electromagnetic wire coil 20 of the pressure cooker, a temperature sensor and other accessories through a wire, and the pressure cooker is controlled to realize different cooking processes.

The power board box 50 is provided with fixing pins 110, and the power board box 50 is fixed on the water collecting ring and/or the base 10 through the fixing pins 110. For example, fixing holes are formed in the fixing legs 110, fixing columns butted with each other are arranged on the water collecting ring and the base 10, the fixing columns on the water collecting ring are butted with the fixing columns on the base 10 after penetrating through the fixing holes and are fixed through screws, and thus the power board box 50 is fixed in the pot body.

As shown in fig. 2 to 4, the power board box 50 includes a back board 100, the back board 100 has a heat dissipation window 120, the power board box is provided with a fan 200, the fan 200 at least partially corresponds to a position between the back board 100 and the power board 300, and the back board 100 has a wind guiding surface 130 between the heat dissipation window 120 and a wind outlet of the fan 200.

The fan 200 is electrified to work to form airflow, and can blow air to the space between the back plate 100 and the power panel 300, when the power panel 300 works, components on the power panel can generate heat, the airflow generated by the fan 200 can take away the heat on the components through the components on the power panel 300, the heat dissipation window 120 is arranged on the back plate 100, so that the airflow can flow out from the space between the power panel 300 and the back plate 100 in time, the flowability of the airflow between the power panel 300 and the back plate 100 is improved, the fan 200 can conveniently send more cold airflow into the space between the back plate 100 and the power panel 300 to better cool the components on the power panel 300, the working stability of the power panel 300 is better ensured, and the service life of the power panel 300 is prolonged.

As shown in fig. 4, the air guide surface 130 is disposed between the heat dissipation window 120 and the air outlet of the fan 200 in the back plate 100, so that the airflow coming out from the air outlet of the fan 200 firstly passes through the air guide surface 130 and then flows out from the heat dissipation window 120, and the flow direction of the airflow can refer to the direction of the arrow in fig. 4, so as to prevent the airflow blown by the fan 200 from flowing out from the heat dissipation window 120 too fast, and the airflow can flow through corresponding components when flowing through the guide surface, so that the airflow can more fully contact with the components on the power board 300, take away more heat, and improve the heat dissipation effect.

As shown in fig. 4-5, the heat dissipation window 120 is offset from the air outlet of the fan 200. Since the width of the fan 200 is smaller than the width of the power board 300, the air outlet width of the fan 200 is smaller than the width of the power board 300, so that the fan 200 can only blow directly at a part of the power board 300. Backplate 100 with air current between the power strip 300 is followed behind the cooling window 120 flows out, the position that cooling window 120 corresponds can form the low pressure, the air current that fan 200 blew out can flow to the low-pressure zone, just so can guide the air current flow direction cooling window 120, the air outlet that cooling window 120 staggers fan 200 can guide the air current diversion for the air current can more fully with the components and parts contact of power strip 300 improves the radiating effect. In other alternative embodiments, the heat dissipation window 120 may also be disposed corresponding to the air outlet of the fan 200, for example, the air outlet of the fan 200, the air guiding surface 130 and the heat dissipation window 120 are located on the same vertical line from bottom to top.

As shown in fig. 4, the wind guide surface 130 is located in a middle region of the back plate 100, and the heat dissipation window 120 is located in two side regions of the back plate 100. Thus, the airflow can diffuse and flow towards the two side areas of the back plate 100 after flowing through the air guide surface 130, which is beneficial to the uniformity of the airflow flowing between the back plate 100 and the power supply board 300, improves the uniformity of heat dissipation, and avoids the phenomenon of local heat accumulation of the power supply board 300. In other alternative embodiments, the air guiding surface 130 may be located at one side of the back plate 100, and all the heat dissipation windows 120 are located at the other side of the back plate 100, but in this way, the air flow mainly flows out from the heat dissipation windows 120 closer to the air guiding surface 130, and the air flow less flows out from the heat dissipation windows 120 farther from the air guiding surface 130, so that the air flow cannot well flow to the position corresponding to the position closer to the air guiding surface 130, the heat dissipation effect on the corresponding component is poor, and heat is easily accumulated in the region.

As shown in fig. 4, the air guide surface 130 is perpendicular to the air outlet of the fan 200, and the surface of the air guide surface 130 is flat.
