In the case where the magnetic induction element 172 is a reed switch, the first setting signal is an on signal and the second setting signal is an off signal. Alternatively, the first setting signal is an off signal and the second setting signal is an on signal.

For the case where the magnetic induction element 172 is a hall sensor, the first set signal is a first set magnetic field intensity, the second set signal is a second set magnetic field intensity, and the first set magnetic field intensity is greater than the second set magnetic steel intensity, or the first set magnetic field intensity is less than the second set magnetic field intensity.

In one embodiment of the application, in particular, the driving mechanism 6 comprises: a movable member 61 and a linking lever 62. Wherein the movable member 61 is movably connected with the pot cover 1. The linkage lever 62 is rotatably connected with the pot cover 1 and is in linkage fit with the movable member 61, and one end of the linkage lever 62 is in linkage fit with the magnetic member 171, and the other end of the linkage lever 62 is correspondingly arranged with the pressureless air exhaust passage 15 for opening or closing the pressureless air exhaust passage 15.

The driving mechanism 6 includes a movable member 61 and an interlocking lever 62. The movable member 61 is movably connected with the pot cover 1, can move relative to the pot cover 1, and the linkage lever 62 is rotatably connected with the pot cover 1, and can rotate relative to the pot cover 1. The interlocking lever 62 is interlocked with the movable member 61, and when the movable member 61 moves relative to the lid 1, the interlocking lever 62 can be driven to move. Since one end of the interlock lever 62 is provided corresponding to the pressureless exhaust passage 15, the interlock lever 62 can open or close the pressureless exhaust passage 15. Meanwhile, the linkage lever 62 is in linkage fit with the magnetic member 171, so that when the linkage lever 62 moves, the magnetic member 171 can be driven to move, the position of the magnetic member 171 is changed, and the output signal of the magnetic induction element 172 is changed.

Further, the driving mechanism 6 further includes a knob 19, where the knob 19 is located above the movable member 61, and one of the knob 19 and the movable member 61 is provided with a driving inclined plane, so that when the knob 19 rotates, the movable member 61 is driven to move downward, and the linkage lever 62 is driven to open the pressureless exhaust passage 15.

Further, the pressure cooking appliance 200 includes a steam valve 18, the steam valve 18 being provided with a steam outlet through which the pressureless exhaust passage 15 communicates with the steam outlet to exhaust the air. The knob 19 is mounted on the steam valve 18, and the steam valve 18 is provided with an pressureless mark and a pressured mark. When the knob 19 is turned to align with the pressed mark, the pressureless exhaust passage 15 is closed; when knob 19 is turned to align with the pressureless flag, pressureless vent passage 15 is opened.

In one particular embodiment, a pressure cooking appliance includes: the pot body is used for containing food to be cooked, and is provided with a magnetic induction element 172, specifically a reed pipe; the pot cover 1, the pot cover 1 is arranged on the pot body; the exhaust assembly comprises a pressure exhaust channel 14 and a non-pressure exhaust channel 15, wherein the pressure exhaust channel 14 comprises an air inlet and a pressure exhaust port, and the pressure exhaust channel 14 is provided with a pressure limiting valve 16; the pressureless exhaust passage 15 is provided with a driving mechanism, which comprises a movable piece movably arranged on the pot cover 1, the movable piece moves downwards to drive a linkage lever to open the pressureless exhaust passage 15; the movable part moves upwards, the pressureless exhaust passage 15 is closed under the action of the self elasticity of the spring, and the pressureless cooking is realized; the magnet cooperates with the interlocking lever to realize the judgment and switching of the current pressure and non-pressure cooking state by the change of the relative position of the magnetic induction element 172 (reed switch).

Since the pressure cooking appliance 200 is provided with the pressure exhaust passage 14 and the non-pressure exhaust passage 15, the pressure exhaust passage 14 and the non-pressure exhaust passage 15 are independent from each other. Wherein the pressurized exhaust passage 14 is used for pressurized cooking and the non-pressurized exhaust passage 15 is used for non-pressurized cooking. Switching between the two cooking modes of pressure cooking and non-pressure is achieved by opening and closing the non-pressure exhaust passage 15. Because the through hole area of the pressureless exhaust passage 15 communicating with the atmosphere is large, true pressureless cooking can be realized.

Further, as shown in fig. 6, the control method of the pressure cooking appliance includes:

powering up, the lid assembly 100 of the pressure cooking appliance is screwed in place;

step S402: judging whether the reed switch is in an on state, if so, executing step S404, and if not, executing step S412;

step S404: controlling the pressure cooker to enter a pressure cooking mode, and starting a function menu to heat;

step S406: judging whether the pressure switch is turned off, if yes, executing step S408, and if not, returning to executing step S406;

step S408: controlling the pressure cooking appliance to enter a pressure maintaining mode;

step S410: judging whether the pressure maintaining time t1 set by the menu is reached, if yes, ending cooking, otherwise, returning to execute the step S410;

Step S412: prompting whether to enter the non-pressure cooking mode, if yes, executing step S414; if no instruction is received, returning to execute the step S402;

step S414: controlling the pressure cooking utensil to enter a non-pressure cooking mode, and starting a function menu to heat;

step S416: and judging whether the cooking duration t2 set by the function menu is reached, if so, ending the cooking, otherwise, returning to execute the step S416.

In other words, after the pressure cooker 200 is powered on (i.e. the power is turned on), the lid assembly 100 is screwed in place, it is first determined whether the reed switch is in the on state.

When the reed switch is judged to be in the on state, the pressure cooking mode (or called pressure cooking mode) is entered. And then starting the function menu to heat, and judging whether the pressure switch is disconnected or not in the heating process. When the pressure switch is judged to be disconnected, the pressure maintaining mode is entered, and when the set pressure maintaining time period t1 is reached, the cooking is completed. When it is determined that the pressure switch is not turned off, heating is continued until the pressure switch is turned off.

And when the reed switch is in the off state, prompting whether to enter the pressureless cooking mode. If the user selects yes, a function menu is started, heating is carried out, and whether the set pressureless cooking time period t2 is reached is judged in the heating process. Ending the cooking when the set pressureless cooking time t2 is judged to be reached; when it is determined that the set pressureless cooking time period t2 is not reached, heating is continued until t2 is reached.

And when the reed switch is in the off state, prompting whether to enter the pressureless cooking mode. If the user selects no, the user is prompted to switch to the pressure cooking mode. When the user rotates the knob 19 to rotate the knob 19 to the pressed mark, the reed switch can be judged to be in the on state at the moment, and then the pressed cooking mode is entered.

The control method solves the problem of mode switching of the product in pressure cooking and non-pressure cooking.

Wherein the cooking body is provided with a pressureless exhaust channel 15 and a pressureless exhaust channel 14. The cross-sectional area of the pressureless exhaust passage 15 is larger than the cross-sectional area of the pressured exhaust passage 14.

Specifically, in the related art, for the sealing mode of the pressure limiting valve, the pressure limiting valve is located outside the closed space formed by the pot cover assembly 100 and the pot body 202 in the cooking process, so that a corresponding pre-tightening force needs to be set to achieve the sealing performance, and for the large exhaust port, the pressure limiting load and the pre-tightening force are too large, so that the cost is increased.

And the pot cover assembly 100 of the present embodiment includes a pot cover 1, a first sealing member 2 and a connecting member 3.

When the pressure in the cooker increases, the direction of the pressure is outward, so that the first sealing piece 2 can be tightly attached to the cooker cover 1, the larger the pressure is, the larger the attaching force is, the more reliable the sealing is, the better the sealing can be realized for the small vent hole 111 and the large vent hole 111 without being limited by the size of the vent hole 111.

Therefore, the problem that the cost is high due to the fact that corresponding pretightening force and pressure limiting load are needed in the sealing mode of the pressure limiting valve in the prior art is effectively solved, and the cost of products is reduced.

When the second connection portion 53 includes the hooking protrusion 531, the hooking protrusion 531 extends in the circumferential direction of the second seal 5 to form a ring-like structure. Correspondingly, the clamping edge 122 of the pot cover 1 also extends along the circumferential direction of the second sealing element 5 to form an annular structure. In this way, the annular hooking protrusion 531 hooks on the annular clamping edge 122, so that the contact area between the second sealing element 5 and the pot cover 1 is effectively increased, and the connection reliability of the second sealing element 5 and the pot cover 1 is improved.
