As shown in fig. 1 to 3, the cooking appliance of the present embodiment includes a pot body 10, a pot cover 20, an upward pressure detecting module 30, a temperature detecting module 40, and a prompting module. Wherein the pan body 10 is used for containing food to be cooked. The pot cover 20 is provided on the pot body 10. The upper pressure detection module 30 is used for detecting an upper pressure signal in the pot body 10, and the temperature detection module is used for detecting the temperature in the pot body 10. The upper pressure detecting module 30 detects whether the pressure in the pot body 10 is in a pressure relief state, the temperature detecting module 40 detects whether the temperature in the pot body 10 is less than a preset cover opening temperature, and when the two detection conditions are simultaneously the same, the prompting module sends out a cover opening prompt.

By applying the technical scheme of the embodiment, when the cover is required to be opened, two conditions need to be judged, one is to detect whether the pot is pressurized or not through the pressurizing detection module 30, and the other is to detect the temperature in the pot through the temperature detection module 40. If the two conditions are met at the same time, the electric pressure cooker can be opened. Compared with the uncapping indication with a single judgment condition in the prior art, the embodiment adopts two judgment conditions to judge whether the uncapping can be performed or not, so that the uncapping indication is more accurate and reliable. Therefore, the technical scheme of the embodiment solves the problem that the cover opening indication of the cooking utensil in the prior art is inaccurate.

The "two detection conditions" mentioned above are respectively that the first detection condition is: the upper pressure detecting module 30 detects whether the inside of the pan body 10 is in a pressure relief state. The second detection condition is: the temperature detection module 40 detects whether the temperature in the pan body 10 is less than a preset cover opening temperature. When the two detection conditions are the same, that is, the upper pressure detection module 30 detects that the pressure in the pot body 10 is released, and the temperature detection module 40 detects that the temperature in the pot body 10 is less than the preset cover opening temperature. At the moment, the electric pressure cooker can be opened, and the prompt module sends out an indication of opening the cover.

Further, when one of the two detection conditions is yes and the other is no, the prompting module makes an overhaul prompt. The above two detection conditions have already been described and are not described in detail herein. One of the two detection conditions is yes, and the other is no two conditions, namely:

first, the upper pressure detecting module 30 detects that the interior of the pot body 10 is in a pressure relief state, but the temperature detecting module 40 detects that the temperature of the interior of the pot body 10 is greater than a preset cover opening temperature. At this point it is indicated that the pressure of the pan 10 has been unloaded, but the temperature is still detected at a higher value. At this time, it is indicated that at least one of the upper pressure detecting module 30 or the temperature detecting module 40 is failed, or other parts in the cooking appliance are failed, and at this time, maintenance should be performed, and the prompting module sends maintenance prompting.

Second, the upper pressure detecting module 30 detects that the inside of the pot body 10 is in an upper pressure state, but the temperature detecting module 40 detects a temperature of the inside of the pot body 10, which is a preset cover opening temperature. At this time, the pressure of the pot 10 is pressurized, but the detected temperature is lower. At this time, it is indicated that at least one of the upper pressure detecting module 30 or the temperature detecting module 40 is failed, or other parts in the cooking appliance are failed, and at this time, maintenance should be performed, and the prompting module sends maintenance prompting.

As shown in fig. 2, in the technical solution of the present embodiment, the prompt module includes an indicator light 50. The indicator light 50 is used for indicating the uncovering. Meanwhile, the number of the indicator lamps 50 may be plural, and the indicator lamps 50 are respectively used for indicating cover opening or maintenance. Of course, the prompt module may also be a speaker, or a pattern displayed on a display screen. The specific form of the prompt module can be determined by one skilled in the art according to actual working requirements.

As shown in fig. 2, the lid 20 includes a liner 21 and a cover 22 provided on the liner 21, and the indicator lamp 50 is provided on the cover 22. Preferably, the indicator light 50 is disposed on the top surface of the face cover 22. The position of the indicator lamp is displayed, so that the indicator lamp is convenient for a user to observe.

As shown in fig. 1, in the technical solution of the present embodiment, the temperature detection module 40 includes a temperature sensing probe, which is disposed on the pot cover 20 and extends toward the pot body 10. The temperature sensing probe can detect the temperature in the inner pot.

As shown in fig. 3, in the technical solution of the present embodiment, the upper pressure detecting module 30 includes a push rod 31 movably disposed on the pot cover 20, and a magnetic member is disposed on the push rod 31. The upper pressure detecting module 30 further comprises a magnetic sensor 32, and when the pressure in the pot body 10 is greater than the preset pressure, the ejector rod 31 is jacked by steam and enables the magnetic piece to move to the sensing range of the magnetic sensor 32. Specifically, when the jack 31 is jacked up, the magnetic sensor 32 detects the magnetic field of the magnetic member, and at this time, the magnetic sensor emits an upward pressure signal. When the jack 31 falls, the magnetic sensor 32 cannot detect the magnetic field of the magnetic member, and the magnetic sensor 32 sends out a pressure relief signal. As for the magnetic strength of the magnetic member, the relative positions of the magnetic member and the magneto-dependent sensor 32, and whether the magneto-dependent sensor 32 detects the numerical limit of the magnetic field, those skilled in the art can design the device according to actual needs.

As shown in fig. 3, in the technical solution of the present embodiment, the cooking appliance further includes a control board, and the control board is electrically connected with the upper pressure detection module 30, the temperature detection module 40, and the prompt module. The signals of the upper pressure detection module 30 and the temperature detection module 40 are fed back to the control board, and the control board operates the prompt module after judging.

Preferably, in the technical solution of the present embodiment, when the ejector rod 31 is lifted by steam, the control board acquires the first temperature detected by the temperature detection module 40, and when the ejector rod 31 falls down by gravity and the temperature detected by the temperature detection module 40 is less than the first temperature, the control board controls the prompt module to send the openable cover signal. Specifically, when the push rod 31 is pushed up by steam, the temperature in the pot 10 is the critical temperature of the upward pressure, and the control board records the critical temperature. When the ejector rod 31 falls and the temperature in the pot body 10 is less than the critical temperature (i.e. the first temperature), the pressure and the temperature in the pot body are both in accordance with the cover opening condition, and the prompt module sends out the prompt of opening the cover. The above control process makes the cover opening prompt more accurate, and the temperature and pressure in the pot body 10 are in a reasonable range when the user opens the cover, so that the user scalds or splashes food.

It should be noted that, the upper pressure detecting module 30 of the present embodiment is a push rod structure driven by steam, that is, the upper pressure detecting module 30 can only detect whether the pressure exists in the pot body 10, but cannot detect a specific value of the pressure. Of course, the upper pressure detection module 30 may be replaced by a more accurate pressure sensor, so as to more accurately monitor the pressure in the pot 10, but the corresponding cost is higher.

As shown in fig. 1, in the technical solution of the present embodiment, the pot cover 20 includes a pot cover main body 23 and an inner pot cover 24 provided on the pot cover main body 23, and a push rod 31 is movably provided on the inner pot cover 24.

Preferably, the cooking appliance is an electric pressure cooker.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
