[0042] Please refer to Figure 1 and Figure 2 , the embodiment of the present application provides a control method of a cooking pot 100, the cooking pot 100 comprising a cooking cavity 10 and a pressure relief cavity 12, the control method of the cooking pot 100 comprising:

[0043] Step S101: controlling the cooking pot 100 to start cooking under the condition that the cooking cavity 10 and the pressure relief cavity 12 are both in a sealed state;

[0044] Step S103: controlling the cooking cavity 10 to communicate with the pressure relief cavity 12 under the condition that the cooking pot 100 enters a pressure relief mode;

[0045] Step S105: controlling the cooking cavity 10 to communicate with the outside of the cooking pot 100 under the condition that the pressure relief parameter of the cooking pot 100 meets a first preset condition in the pressure relief mode, the pressure relief parameter comprising at least one of a pressure relief time length and a pressure of the cooking cavity 10.

[0046] The control method of the cooking pot 100 described above controls the cooking pot 100 to gradually relieve pressure between the cooking cavity 10, the pressure relief cavity 12 and the outside, which can shorten the pressure relief time, thereby reducing the loss of aroma substances and water vapor and improving the cooking effect.

[0047] Specifically, the pressure cooker is an electrical appliance that uses high pressure to increase the cooking temperature and shorten the cooking time. In order to ensure safety in use, the pot cover can only be opened when the pressure in the pot is equal to the atmospheric pressure after cooking is completed.

[0048] In the related art, a pressure relief port is formed on the pot cover of the pressure cooking utensil 100, and a pressure relief valve is arranged. After cooking is completed, the pressure relief valve is opened to release the pressure in the pressure cooking utensil 100. This process generally takes 15 minutes or more, and the long pressure relief time may also cause the food to stick to the bottom during the juice collection, resulting in cooking failure.

[0049] If the user needs to alternate between pressure cooking and non-pressure cooking modes, the pressure relief time will seriously affect the cooking progress, thereby causing poor continuity of cooking and long cooking time, resulting in poor user experience.

[0050] Based on the above problems, the embodiment of the present application provides a control method of a cooking utensil 100, which has a cooking cavity 10 and a pressure relief cavity 12. By controlling the sealing or communication of the cooking cavity 10 and the pressure relief cavity 12, the pressure in the cooking cavity 10 is controlled.

[0051] In the cooking state, the cooking cavity 10 is in a sealed state and does not communicate with the pressure relief cavity 12 or the outside of the cooking utensil 100. In the cooking state, the pressure and temperature in the cooking cavity 10 can be quickly raised, so that the food can be quickly cooked in a high-temperature and high-pressure cooking environment.

[0052] After the cooking program of the cooking utensil 100 is completed, the pressure relief mode is entered. In the pressure relief mode, the pressure relief cavity 12 and the cooking cavity 10 are controlled to communicate, and the pressure in the cooking cavity 10 is divided into the pressure relief cavity 12. When the pressure relief parameters of the cooking utensil 100 meet the first preset condition, the cooking cavity 10 is controlled to communicate with the outside of the cooking utensil 100, so that the cooking cavity 10 realizes step-by-step pressure relief and rapid pressure relief.

[0053] Among them, the pressure relief parameters include at least one of the pressure relief time and the pressure in the cooking cavity 10, that is, the preset condition includes that the pressure in the cooking cavity 10 reaches a preset pressure or the pressure relief time of the cooking cavity 10 reaches a preset time.

[0054] In one example, the cooking cavity 10 is controlled to communicate with the pressure relief cavity 12 when the cooking utensil 100 enters the pressure relief mode. The cooking cavity 10 is controlled to communicate with the outside of the cooking utensil 100 when the pressure in the cooking cavity 10 reaches a preset pressure. After the cooking cavity 10 communicates with the pressure relief cavity 12, the pressure in the cooking cavity 10 is relieved to the pressure relief cavity 12, and the pressure in the cooking cavity 10 gradually decreases. The preset pressure can be a pressure at which the pressure in the cooking cavity 10 is relieved to the pressure relief cavity 12 to a certain extent, the pressure in the cooking cavity 10 no longer changes or changes little. The preset pressure can be determined by experimental simulation. The preset pressure is related to the volume ratio of the cooking cavity 10 and the pressure relief cavity 12, the diameter of the pressure relief port, and other parameters.

[0055] In one example, the cooking cavity 10 is controlled to communicate with the pressure relief cavity 12 when the cooking utensil 100 enters the pressure relief mode. The cooking cavity 10 is controlled to communicate with the outside of the cooking utensil 100 when the time for which the cooking cavity 10 communicates with the pressure relief cavity 12 reaches a preset time. The preset time can be the time for which the pressure in the cooking cavity 10 and the pressure in the pressure relief cavity 12 reach the same or similar levels after the cooking cavity 10 communicates with the pressure relief cavity 12. The preset time can be determined by experimental simulation. The preset time is related to the volume ratio of the cooking cavity 10 and the pressure relief cavity 12, the diameter of the pressure relief port, and other parameters.

[0056] The user starts pressure cooking, and the cooking utensil 100 enters a cooking state and starts heating. At this time, the cooking cavity 10 is in a sealed state and does not communicate with the pressure relief cavity 12 or the outside of the cooking utensil 100. As the cooking process proceeds, the pressure in the cooking cavity 10 gradually increases. After the cooking state ends, the cooking utensil 100 enters the pressure relief mode. Before the cooking cavity 10 communicates with the pressure relief cavity 12, the pressure in the cooking cavity 10 is PI. After the cooking cavity 10 communicates with the pressure relief cavity 12, the pressure in the cooking cavity 10 is divided into the pressure relief cavity 12, and the pressure in the cooking cavity 10 decreases to P2, completing the multi-cavity pressure relief. At this time, the cooking cavity 10 is controlled to communicate with the outside of the cooking utensil 100, and the P2 pressure in the cooking cavity 10 is relieved to the outside through the exhaust port, and the pressure in the cooking cavity 10 decreases to P3. At this time, because P2>P3, the aroma and water vapor in the pressure relief cavity 12 can flow back to the cooking cavity 10, thereby reducing the loss of water vapor and aroma generated during cooking during pressure relief. At the same time, the cooking cavity 10 continues to be relieved until it decreases to atmospheric pressure P0, completing the rapid pressure relief process. Because P2 is much smaller than PI after the pressure is divided, the time for which the pressure decreases from P2 to P0 will be very short, and rapid pressure relief can be achieved.

[0057] In some embodiments, the pressure relief cavity 12 communicates with the cooking cavity 10 through the first through hole 14 and communicates with the outside of the cooking utensil 100 through the second through hole 16. The control method of the cooking utensil 100 includes:

[0058] In the pressure relief mode, when the pressure relief parameter of the cooking utensil 100 meets the first preset condition, the cooking cavity 10 is controlled to be in communication with the outside of the cooking utensil 100, and at the same time, the pressure relief cavity 12 is controlled to be in communication with the outside of the cooking utensil 100.

[0059] In this way, the speed of the cooking cavity 10 to vent outward is faster.

[0060] Specifically, the pressure relief cavity 12 is in communication with the cooking cavity 10 through the first through hole 14, and in communication with the outside of the cooking utensil 100 through the second through hole 16. The cooking cavity 10 is in communication with the outside of the cooking utensil 100 through the third through hole 17.

[0061] The pressure relief cavity 12 is first in communication with the cooking cavity 10 through the first through hole 14, and the pressure in the cooking cavity 10 is shunted to the pressure relief cavity 12. When the pressure relief parameter in the cooking cavity 10 meets the first preset condition, the cooking cavity 10 is controlled to be in communication with the outside of the cooking utensil 100 through the third through hole 17. Since the aroma and water vapor in the pressure relief cavity 12 can flow back to the cooking cavity 10, the loss of water vapor and aroma generated during cooking during pressure relief can be reduced.

[0062] Alternatively, the pressure relief cavity 12 is first in communication with the cooking cavity 10 through the first through hole 14, and the pressure in the cooking cavity 10 is shunted to the pressure relief cavity 12. When the pressure relief parameter in the cooking cavity 10 meets the first preset condition, the cooking cavity 10 is controlled to be in communication with the outside of the cooking utensil 100, and at the same time, the pressure relief cavity 12 is controlled to be in communication with the outside of the cooking utensil 100.

[0063] In some embodiments, the first through hole 14 and the second through hole 16 are arranged to be staggered along a first direction.

[0064] In this way, the loss of water vapor and aroma generated during cooking during pressure relief can be reduced.

[0065] Specifically, since the first through hole 14 and the second through hole 16 are arranged to be staggered along a first direction, the aroma and water vapor in the pressure relief cavity 12 can flow back to the cooking cavity 10, wherein the first direction is the left-right direction shown in FIG. 1, and the first through hole 14 and the second through hole 16 are arranged to be staggered along the first direction, indicating that there is no overlapping area between the projections of the first through hole 14 and the second through hole 16 in the vertical direction of the first direction. Figure 1 Figure 1 When the pressure relief cavity 12 vents to the outside along the up-down direction shown in FIG. 1, the path of the pressure relief is not vertically upward in the up-down direction, but has a certain tortuosity, so that the loss of water vapor and aroma generated during cooking can be reduced.

[0066] ​In some embodiments, the pressure relief cavity 12 is in communication with the cooking cavity 10 through the first through hole 14 and with the outside of the cooking utensil 100 through the second through hole 16, and the control method of the cooking utensil 100 comprises:

[0067] In the pressure relief mode, when the pressure relief parameter of the cooking utensil 100 meets the first preset condition and then meets the second preset condition, the pressure relief cavity 12 is controlled to be in communication with the outside of the cooking utensil 100 through the second through hole 16.

[0068] In this way, the pressure relief time of the cooking utensil 100 is short, and the cooking effect is good.

[0069] Specifically, the user starts pressure cooking, and the cooking utensil 100 enters a cooking state and starts heating work. At this time, the cooking cavity 10 is in a sealed state and is not in communication with the pressure relief cavity 12 and the outside of the cooking utensil 100. As the cooking process proceeds, the pressure in the cooking cavity 10 gradually rises. After the cooking state ends, the cooking utensil 100 enters a pressure relief mode. Before the cooking cavity 10 is in communication with the pressure relief cavity 12, the pressure in the cooking cavity 10 is P1. After the cooking cavity 10 is in communication with the pressure relief cavity 12, the pressure in the cooking cavity 10 is divided into the pressure relief cavity 12, the pressure in the cooking cavity 10 decreases to P2, and the multi-cavity pressure relief is completed. Then the cooking cavity 10 is controlled to be in communication with the outside of the cooking utensil 100, and the pressure relief continues. When the pressure in the cooking cavity 10 reaches P3, the pressure relief cavity 12 is controlled to be in communication with the outside of the cooking utensil 100, so that the pressure relief cavity 12 is relieved, thereby realizing the simultaneous pressure relief of the cooking cavity 10 and the pressure relief cavity 12, until the pressure in the cooking cavity 10 decreases to atmospheric pressure P0, and the rapid pressure relief process is completed. The multi-cavity pressure relief, and the pressure of each cavity is relatively small, so the pressure relief speed is faster. At the same time, the aroma and water vapor discharged with the pressure relief can maintain good cooking effect.

[0070] Please refer to Figure 3 In some embodiments, the pressure relief cavity 12 is in communication with the cooking cavity 10 through the first through hole 14, and the control method of the cooking utensil 100 comprises:

[0071] Step S107: In the pressure relief mode, when the pressure relief parameter of the cooking utensil 100 meets the first preset condition, the cooking cavity 10 is controlled to be in communication with the outside of the cooking utensil 100, and the cooking cavity 10 and the pressure relief cavity 12 are simultaneously controlled to be closed.

[0072] Step S109: When the pressure relief parameter of the cooking utensil 100 meets the second preset condition, the cooking cavity 10 is controlled to be in communication with the pressure relief cavity 12.

[0073] In this way, the cooking cavity 10 can be gradually and rapidly pressure relieved.

[0074] Specifically, after the cooking utensil 100 enters the pressure relief mode, first, the cooking cavity 10 is controlled to be in communication with the pressure relief cavity 12, and the pressure in the cooking cavity 10 is shunted to the pressure relief cavity 12. In the case that the pressure relief parameter satisfies the first preset condition, the cooking cavity 10 is controlled to be in communication with the outside of the cooking utensil 100, and meanwhile the cooking cavity 10 is controlled to be closed with the pressure relief cavity 12. At this time, the pressure in the cooking cavity 10 continues to be shunted to the outside of the cooking utensil 100, and gradual and rapid pressure relief can be realized. In the case that the pressure relief parameter of the cooking utensil 100 satisfies the second preset condition, the cooking cavity 10 is controlled to be in communication with the pressure relief cavity 12 again, at this time, the pressure in the pressure relief cavity 12 is greater than the pressure in the cooking cavity 10, and the aroma and water vapor in the pressure relief cavity 12 can flow back to the cooking cavity 10, thereby reducing the loss of water vapor and aroma generated during cooking during pressure relief.

[0075] In some embodiments, the pressure relief cavity 12 is in communication with the cooking cavity 10 through the first through hole 14, in communication with the outside of the cooking utensil 100 through the second through hole 16, and the cooking cavity 10 is in communication with the outside of the cooking utensil 100 through the third through hole 17;

[0076] The cooking utensil 100 comprises a first switch valve 18, a second switch valve 19 and a third switch valve 20. When the first switch valve 18 is in an open state, the pressure relief cavity 12 is in communication with the cooking cavity 10 through the first through hole 14, and when the first switch valve 18 is in a closed state, the cooking cavity 10 and the pressure relief cavity 12 are sealed and isolated from each other. When the second switch valve 19 is in an open state, the pressure relief cavity 12 is in communication with the outside of the cooking utensil 100 through the second through hole 16, and when the second switch valve 19 is in a closed state, the pressure relief cavity 12 is sealed and isolated from the outside of the cooking utensil 100. When the third switch valve 20 is in an open state, the cooking cavity 10 is in communication with the outside of the cooking utensil 100, and when the third switch valve 20 is in a closed state, the cooking cavity 10 is sealed and isolated from the outside of the cooking utensil 100.

[0077] In this way, by controlling the first switch valve 18, the second switch valve 19 and the third switch valve 20, the pressure relief cavity 12 can be controlled to be in communication with the cooking cavity 10, the pressure relief cavity 12 and the outside of the cooking utensil 100, and the cooking cavity 10 and the outside of the cooking utensil 100.

[0078] Specifically, the first switch valve 18 is arranged at the first through hole 14 and is used to open or close the first through hole 14, so as to control the cooking cavity 10 and the pressure relief cavity 12 to be in communication or sealed and isolated from each other. The second switch valve 19 is arranged at the second through hole 16 and is used to open or close the second through hole 16, so as to control the pressure relief cavity 12 and the outside of the cooking utensil 100 to be in communication or sealed and isolated from each other. The third switch valve 20 is arranged at the third through hole 17 and is used to open or close the third through hole 17, so as to control the cooking cavity 10 and the outside of the cooking utensil 100 to be in communication or sealed and isolated from each other.

[0079] In summary, the control method of the cooking utensil 100 described above controls the cooking utensil 100 to gradually release pressure between the cooking cavity 10, the pressure relief cavity 12 and the outside, which can shorten the pressure relief time, reduce the loss of flavor substances and water vapor, improve the cooking effect and improve the user experience.

[0080] As shown in Figure 4 The control device 22 of an embodiment of the present application includes a processor 24 and a memory 28, and the memory 28 stores a computer program which, when executed by the processor 24, implements the steps of the control method of the cooking utensil 100 of any embodiment.

[0081] Specifically, the control device 22 can include a control panel, a computer board or the like.

[0082] A cooking utensil 100 of an embodiment of the present application includes the control device 22 of the above embodiment.

[0083] Specifically, the control device 22 is installed on the cooking utensil 100. For example, the cooking utensil 100 includes a pot body 34 and a cover body 36, and the control device 22 can be installed on the pot body 34. Alternatively, the control device 22 can be installed on the cover body. Alternatively, the control device 22 can be installed at other positions outside the cover body and the pot body.

[0084] In some embodiments, the cooking utensil 100 includes a pot body 34 and a cover body 36, the cooking cavity 10 is arranged in the pot body 34, and the pressure relief cavity 12 is arranged in the cover body 36. When the cover body 36 is closed to the pot body 34, the cooking cavity 10 is sealed.

[0085] In this way, when the cover body 36 is closed to the pot body 34, the cooking cavity 10 can be sealed.

[0086] Specifically, the cooking utensil 100 includes a pot body 34 and a cover body 36, the cooking cavity 10 is arranged in the pot body 34, and the cover body 36 is closed to the pot body 34 to seal the cooking cavity 10. The pressure relief cavity 12 is arranged in the cover body 36, and the pressure relief cavity 12 and the cooking cavity 10 are communicated through the first through hole 14 arranged on the cover body 36.

[0087] In some embodiments, the volume ratio of the cooking cavity 10 and the pressure relief cavity 12 is greater than or equal to 5:1.

[0088] In this way, the pressure relief cavity 12 has a certain volume, which helps the cooking cavity 10 to better release pressure.

[0089] Specifically, the pressure relief cavity 12 is used to achieve the first-stage pressure relief of the cooking cavity 10. If the volume of the pressure relief cavity 12 is too small, the pressure relief effect is poor and the cooking cavity 10 cannot be quickly relieved. According to experimental tests, when the volume ratio of the cooking cavity 10 to the pressure relief cavity 12 is greater than or equal to 5:1, the quick pressure relief with a relatively obvious effect can be achieved.

[0090] In the illustrated embodiment, the pressure relief cavity 12 is arranged in the cover body 36 of the cooking utensil 100. The cover body 36 has a certain thickness, and the volume ratio of the cooking cavity 10 to the pressure relief cavity 12 can be greater than or equal to 5:1, so that the cooking utensil 100 has a better pressure relief effect, and the overall structure of the cooking utensil 100 is not changed, and the use process is also simpler and more convenient.

[0091] In other embodiments, a pressure relief box can be arranged on the cooking utensil 100, and the pressure relief cavity 12 is arranged in the pressure relief box. A through hole is arranged on the pot body 34 or the cover body 36 to communicate with the pressure relief box and the cooking cavity 10, so as to achieve the quick pressure relief of the cooking utensil 100. The external pressure relief box can make the pressure relief cavity 12 have a larger volume and a better pressure relief effect.

[0092] In other embodiments, two or more pressure relief boxes can be arranged at the same time to simultaneously perform pressure relief. Alternatively, the pressure relief cavity 12 is arranged in the cover body 36 of the cooking utensil 100, and an external pressure relief box is arranged to communicate with the cooking cavity 10, so as to achieve the simultaneous pressure relief of multiple pressure relief cavities 12.

[0093] In some embodiments, the first through hole 14, the second through hole 16 and the third through hole 17 are arranged on the cover body 36, and the cooking utensil 100 comprises a first switch valve 18, a second switch valve 19 and a third switch valve 20. The first switch valve 18 is arranged at the first through hole 14, the second switch valve 19 is arranged at the second through hole 16, and the third switch valve 20 is arranged at the third through hole 17.

[0094] In some embodiments, the control device 22 is electrically connected to the first switch valve 18, the second switch valve 19 and the third switch valve 20, and the control device 22 is used to control the first switch valve 18, the second switch valve 19 and the third switch valve 20 to switch between the open state and the closed state.

[0095] In this way, the automatic pressure relief of the cooking utensil 100 can be achieved.

[0096] Specifically, the control device 22 is electrically connected to the first switch valve 18, the second switch valve 19 and the third switch valve 20, and a pressure relief program of the cooking utensil 100 can be set to achieve the switching or alternating use of the cooking utensil 100 between the cooking mode and the pressure relief mode, so as to achieve different cooking functions.

[0097] For example, the cooking pot 100 can include a pressure cooking mode, a non-pressure cooking mode, and a pressure relief mode.

[0098] In the pressure cooking mode, the first switch valve 18, the second switch valve 19, and the third switch valve 20 are all closed. The cooking cavity 10 can be quickly heated and pressurized.

[0099] In the non-pressure cooking mode, the first switch valve 18, the second switch valve 19, and the third switch valve 20 can be controlled to be all opened, or the third switch valve 20 can be controlled to be opened, or the first switch valve 18 and the second switch valve 19 can be controlled to be opened, so that the cooking cavity 10 is in communication with the outside of the cooking pot 100, and the pressure in the cooking cavity 10 is consistent with the outside of the cooking pot 100.

[0100] In the pressure relief mode, the cooking pot 100 can be quickly depressurized according to the control method of the cooking pot 100 described above.

[0101] By controlling the first switch valve 18, the second switch valve 19, and the third switch valve 20 to switch between the opened state and the closed state through the control device 22, the cooking pot can be switched between the pressure cooking mode, the non-pressure cooking mode, and the pressure relief mode according to the cooking method and the cooking material.

[0102] In some embodiments, the first through hole 14 and the second through hole 16 are staggered in the first direction on the cover 36.

[0103] In this way, when the first through hole 14 and the second through hole 16 are both opened for pressure relief, the loss of the aroma and the steam in the pressure relief cavity 12 is prevented.

[0104] Specifically, when the pressure relief cavity 12 is depressurized along the up-down direction to the outside, the path of the pressure relief is not vertically upward in the up-down direction, but has a certain tortuosity, so that the loss of the steam and the aroma generated by cooking can be reduced. Figure 1

[0105] The control device 22 and the cooking pot 100 described above can shorten the pressure relief time by controlling the cooking pot 100 to be depressurized between the cooking cavity 10, the pressure relief cavity 12, and the outside, so that the loss of the aroma and the steam is reduced, and the cooking effect is improved.

[0106] It should be noted that the above explanations and descriptions of the embodiments and beneficial effects of the control method of the cooking pot 100 are also applicable to the control device 22 and the cooking pot 100 of the embodiments of the present application. To avoid redundancy, they will not be described in detail here.
