When the gas pressure in the cooking cavity reaches a preset value, the high-pressure gas in the exhaust pipe 11 can push open the pressure limiting valve 12, an exhaust port (not numbered) of the exhaust pipe 11 is opened, and the high-pressure gas in the cooking cavity is exhausted outwards through the exhaust pipe 11, the exhaust channel 10 and the exhaust hole 101. It can be understood that a gap is reserved between the exhaust hole 101 and the pot body 2, so that the exhaust hole 101 can exhaust air outwards.

The top of the pot body 2 is provided with a temperature sensor 20, and the exhaust hole 101 exhausts air towards the temperature sensor 20. When the exhaust pipe 11 exhausts air through the exhaust passage 10, high-temperature gas flows out from the exhaust passage 10 to contact with the surface of the temperature sensor 20, the temperature sensor 20 detects temperature change and transmits a signal to a control device (not shown) of the cooking appliance, and the control device controls the on-off of the heating circuit to ensure that the pressure in the cooking cavity does not rise any more, so that the cooking appliance can cook safely. Compared with a pressure switch, the pressure control mode of the temperature sensor 20 is more accurate, and the problem of inaccurate pressure control caused by deformation for a long time in use is solved.

The cooker cover 1 is provided with an inner cover 13, an upper cover covering the inner cover 13 and a steam cover 14 arranged on the upper cover, the upper cover is provided with a containing cavity 102 containing the pressure limiting valve 12, the top of the containing cavity 102 is open, and the steam cover 14 covers the containing cavity 102 and seals the opening at the top.

An exhaust port (not numbered) extends downward through the slider 103, and the temperature sensor 20 is mounted in the guide groove 211 directly below the exhaust port (not numbered). The decoration cover 16, the face cover 15 and the steam cover 14 together form the exhaust passage 10 with an open bottom, which can simplify the structure of the pot cover 1 and facilitate the manufacturing.

Referring to fig. 3, the pot body 2 includes a middle plate 21, an outer casing 22, a heat-insulating cover 23, an inner pot 24 and a heating plate 25, the heat-insulating cover 23 is located in the outer casing 22, the inner pot 24 is located in the heat-insulating cover 23, and the heating plate 25 is located between the inner pot 24 and the heat-insulating cover 23 to heat the inner pot 24. The middle plate 21 is positioned on the top of the pan body 2, and the aforementioned guide groove 211 is formed on the top surface of the middle plate 21.

Referring to fig. 7, a magnet 142 is disposed inside the steam cover 14, a reed switch 26 is correspondingly disposed on the pot body 2, and the reed switch 26 and the magnet 142 form a switch detection. The steam cover 14 is detachable and can be cleaned independently, and after the pot cover 1 is covered on the pot body 2 and rotated in place, the reed switch 26 receives the magnetic signal of the magnet 142 and sends a signal to the control device of the cooking appliance. On the contrary, if the steam cover 14 is neglected to be installed or the pot cover 1 is not rotated in place, no signal is given, so that the user can be reminded to install the steam cover 14 and the user can be reminded to rotate the pot cover 1 in place. The magnets 142 are located outside the exhaust passage 10, and the magnets 142 are hidden by the corresponding steam cover 14 and the face cover 15 by providing some blocking walls (not numbered). The reed switch 26 is hidden in the top of the pot body 2, and the surface cover 15 is provided with a slot 151 right below the magnet 142, so that the reed switch 26 can smoothly receive a magnetic signal of the magnet 142.

As shown in fig. 2, 5 and 6, the middle plate 21 has a through hole 212 in the guide groove 211, and the temperature sensor 20 is assembled in the through hole 212 and exposed at an upper surface thereof to contact with the high-temperature gas discharged from the exhaust port (not numbered). The temperature sensor 20 is arranged on the middle plate 21 of the pot body 2 instead of the pot cover 1, so that the wiring between the pot cover and the pot body is not needed, and the structure can be simplified. The pot body 2 is provided with the sealing ring 27, and the sealing ring 27 is arranged between the through hole 212 and the temperature sensor 20 in a sealing manner, so that the phenomenon that condensed water generated by high-temperature gas in the guide groove 211 flows into the pot body 2 to influence electric devices in the pot body 2 is avoided.

The pot body 2 is further provided with a fixing plate 28 which is buckled and installed on the bottom side of the middle plate 21, and the temperature sensor 20 and the reed pipe 26 are clamped and fixed between the middle plate 21 and the fixing plate 28. The reed switch 26 and the temperature sensor 20 can be easily and reliably fixed by the fixing plate 28. The fixing plate 28 is further provided with a rib 281 against the temperature sensor 20 to reliably position the temperature sensor 20.

The temperature sensor 20 includes a top case 201, a bottom case 202, and a thermistor 203 interposed between the top case 201 and the bottom case 202, and the top case 201 is exposed through a through hole 212 of the middle plate 21. When the pressure in the cooker is close to the set pressure value, the pressure limiting valve 12 opens the exhaust pipe 11, the steam overflows from the exhaust pipe 11 and is transmitted to the top shell 201 of the temperature sensor 20 through the exhaust hole 101 of the exhaust channel 10, the temperature of the top shell 201 begins to rise, the resistance value changes after the thermistor 203 can sense the temperature, and a signal is fed back to the control device, so that the on-off of the heating circuit is controlled, and the purpose of controlling the pressure is achieved.

The side wall of the heat preservation cover 23 is provided with a grounding insertion sheet 231, the bottom shell 202 is electrically connected with the grounding insertion sheet 231 through the grounding wire 204, so that the temperature sensor 20 is grounded through the heat preservation cover 23, the safety requirements are met, and the length of the grounding wire 204 is short.
