However, the function of the wireless module is relatively single, which cannot meet the use demand of consumers.

[0004] Therefore, the wireless module of the cooking utensil in the related art has the problem of single function, which cannot meet the use demand of consumers. UTILITY MODEL CONTENTS

[0005] The utility model provides a kind of cooking utensil to solve the problem of single function of wireless module of cooking utensil in the related art, which cannot meet the use demand of consumers.

[0007] The utility model discloses a technical scheme, this cooking utensil includes pot body, cover and wireless module, the upper module of wireless module and the lower module cooperate to detect the opening and closing of the cover, cover is provided with the upper pressure detection piece that can carry out upper pressure detection and the temperature detection piece that can carry out temperature detection, upper pressure detection piece and temperature detection piece are all electrically connected with the upper module to transmit upper pressure signal and temperature signal.Using the above structure, wireless module can realize opening and closing cover detection function, upper pressure detection function and temperature detection function, that is, wireless module can realize three different functions simultaneously, can meet the use demand of consumers.

[0008] Further, the cooking utensil further comprises a stop valve which is floatably arranged on the cover body, the upper pressure detection member comprises a trigger arranged on the stop valve and an upper pressure sensing member arranged on the cover body, the upper pressure sensing member is electrically connected with the circuit board of the upper module, when the stop valve moves to the floating position, the trigger can trigger the upper pressure sensing member to work to perform the upper pressure detection. The arrangement of the stop valve can ensure that during the cooking process, when the pressure in the pot reaches a certain value, the stop valve floats and limits the cooperation with the stop plate on the cover body, at this time, the cover body cannot rotate relative to the pot body, that is, the cover cannot be opened, which can improve the cooking safety. The trigger of the upper pressure detection member is integrated on the stop valve, and the floating of the stop valve can trigger the upper pressure sensing member to realize the upper pressure detection. This structure can improve the integration of the components in the cover body.

[0009] Further, the trigger comprises a magnetic member, and the upper pressure sensing member comprises a magnetic control switch. The cooperation of the magnetic member and the magnetic control switch makes the trigger of the upper pressure detection member more sensitive, ensures the accuracy of the pressure detection, and improves the cooking safety.

[0010] Further, the temperature detection member comprises an NTC arranged on the cover body, the NTC is arranged in series with the upper pressure sensing member and is electrically connected with the circuit board of the upper module. The use of the NTC can monitor the temperature change inside the cooking utensil in real time. In the cooking process such as slow stewing and soup boiling which requires long time stable temperature, the NTC can provide continuous temperature monitoring to ensure the taste and nutrition of the food cooking. The series arrangement of the NTC and the upper pressure sensing member makes the upper pressure detection of the cooking utensil more accurate. Specifically, according to the sensing of the magnetic control switch, the temperature detection of the NTC is also detected, and the software determines that when the temperature is higher than the preset temperature, both conditions are met to determine the upper pressure (in normal case, the temperature is lower than the preset temperature, and the upper pressure will not be determined).

[0011] Further, the stop valve comprises a valve body, a safety valve core and a spring, the valve body is provided with a vent hole penetrating along an axial direction thereof, the safety valve core is movably arranged at an orifice of the vent hole, one end of the spring is in abutment with the valve body, and the other end of the spring is in abutment with the safety valve core, so that the safety valve core blocks the orifice of the vent hole; and / or, the cover body further comprises an inner liner located below the face cover, the upper pressure sensing piece is arranged on the inner liner, the inner liner is provided with an avoiding notch, and the end of the upper pressure sensing piece facing the stop valve is arranged corresponding to the avoiding notch; the face cover is provided with an observation hole penetratingly arranged, the observation hole is surrounded by a cylinder body extending downward, the upper end of the stop valve is arranged in the cylinder body, and the cylinder body extends below the avoiding notch. The stop valve is designed in this way, which can ensure that the safety valve core can stably block the vent hole under normal cooking pressure, so as to prevent steam leakage, and when the pressure abnormally rises, the safety valve core can overcome the force of the spring and open the vent hole to release the excess pressure. This design is particularly crucial in high-pressure cooking appliances, which can effectively avoid safety accidents caused by excessive pressure. Since the inner liner is provided with the avoiding notch, and the end of the upper pressure sensing piece facing the stop valve is arranged corresponding to the avoiding notch, the avoiding notch can reduce the interference of the inner liner on the upper pressure sensing piece. For example, the trigger piece comprises a magnetic piece, and the upper pressure sensing piece comprises a magnetic control switch, and the avoiding notch can increase the magnetic flux of the magnetic control switch. Moreover, since the cylinder body extends below the avoiding notch, the cylinder body can block the steam at the stop valve, so as to avoid the high-temperature steam directly impacting the magnetic control switch.

[0012] Further, the stop valve has a mounting groove, the mounting groove is an annular structure extending along a circumferential direction of the stop valve, and the magnetic piece is an annular magnet embedded in the mounting groove. Embedding the annular magnet in the mounting groove can not only ensure the stable position of the magnetic piece, but also avoid the magnetic piece falling off due to high temperature during cooking, thereby improving the durability and safety of the cooking appliance.

[0013] Further, the magnetic control switch is arranged on one side of the stop valve in a transverse direction and is spaced apart from the stop valve. Spacing the magnetic control switch from the stop valve can avoid the high-temperature steam directly impacting the magnetic control switch and affecting its normal work. At the same time, since the magnetic control switch is sensitive to the magnetic field, even if it is kept at a certain distance from the stop valve, it can accurately detect the movement of the magnetic piece to realize upper pressure detection. In cooking appliances that need to monitor high-pressure environments, such as electric pressure cookers, this design can ensure the long-term stable work of the magnetic control switch and improve the accuracy and reliability of pressure detection.

[0014] Further, the distance between the magnetic piece and the magnetic control switch in the transverse direction is D, and 7mm≤D≤9mm. By accurately controlling the distance between the magnetic piece and the magnetic control switch in the transverse direction, the detection sensitivity can be ensured while avoiding false triggering caused by too close distance, thereby improving the stability and accuracy of the upper pressure detection piece.

[0015] Further, the distance between the magnetic member and the magnetic switch in the vertical direction is H; when the stop valve is in the floating position, 6mm≤H<8mm; when the stop valve is in the initial position, 13mm≤H≤15mm. The on-off sensing distance of the magnetic switch is designed to be >13mm OFF and <8mm ON. When the stop valve is in the initial position, the magnetic switch is not sensed. When the stop valve is in the floating position, the magnetic switch is sensed (before the stop valve moves to the floating position, the magnetic switch can already sense the magnetic member).

[0016] Further, the temperature detection member and the stop valve are arranged in the lateral direction; and / or, the temperature detection member is fixed on the cover body through a first support, and the stop valve is fixed on the cover body through a second support; and / or, the upper module and the lower module are matched to detect the cover opening and closing. By using the above structure, the temperature detection interference can be reduced, and the temperature detection is more accurate, especially at the moment when the stop valve falls, at which time the external gas may enter the pot, at which time the temperature data needs to be collected, the temperature detection member is far away from the stop valve, and the temperature detection accuracy will be better.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0035] like Figures 1 to 8 As shown, this embodiment of the utility model provides a cooking appliance, which includes a pot body 10, a lid 20, and a wireless module 30. The lid 20 is detachably mounted on the pot body 10 and includes a top cover 22. The wireless module 30 includes a lower module 31 mounted on the pot body 10 and an upper module 32 mounted on the lid 20, with the upper module 32 and lower module 31 wirelessly connected. The upper module 32 and lower module 31 cooperate to detect lid opening and closing. The lid 20 is provided with a pressure detection element 40 for pressure detection and a temperature detection element 50 for temperature detection, both of which are electrically connected to the upper module 32.

[0036] The upper module 32 and the lower module 31 of the wireless module 30 are matched to perform the cover opening and closing detection, the cover 20 is provided with the upper pressure detection piece 40 capable of performing the upper pressure detection and the temperature detection piece 50 capable of performing the temperature detection, and the upper pressure detection piece 40 and the temperature detection piece 50 are electrically connected with the upper module 32 to transmit the upper pressure signal and the temperature signal. By adopting the above structure, the wireless module 30 can realize the cover opening and closing detection function, the upper pressure detection function and the temperature detection function, that is, the wireless module 30 can realize three different functions at the same time, and can meet the use demand of consumers.

[0037] It should be noted that the cover opening and closing detection is an important link to ensure the safety of the cooking utensil, and is used to detect whether the cover 20 is placed on the pot body 10 and whether the cover 20 is placed to be buckled with the pot body 10. The upper pressure detection is used to detect whether the cooking utensil is in the upper pressure state, that is, whether the pressure in the pot reaches the preset value. The temperature detection is to detect the temperature in the pot.

[0038] In addition, by integrating the upper pressure detection piece and the temperature detection piece, the cooking utensil provided in the embodiment can monitor the pressure and temperature in the cooking process, and ensure the quality and safety of food cooking. It is suitable for scenes such as home kitchen and restaurant back kitchen, and can play an important role especially in high-pressure cooking, stewing and other dishes that need to control the cooking conditions.

[0039] As shown in FIG. 1, Figure 2 The cooking utensil further comprises a non-opening valve 60 which is floatingly arranged on the cover 20. The arrangement of the non-opening valve 60 can ensure that during the cooking process, when the pressure in the pot reaches a certain value, the non-opening valve 60 floats up and limits the cooperation with the non-opening plate on the cover 20, at this time, the cover 20 cannot rotate relative to the pot body 10, that is, the cover cannot be opened, which can improve the cooking safety.

[0040] The upper pressure detection piece 40 comprises a trigger piece 41 arranged on the non-opening valve 60 and an upper pressure sensing piece 42 arranged on the cover 20, and the upper pressure sensing piece 42 is electrically connected with the circuit board of the upper module 32. When the non-opening valve 60 moves to the floating position, the trigger piece 41 can trigger the upper pressure sensing piece 42 to work to perform the upper pressure detection. By adopting the above structure, the trigger piece 41 of the upper pressure detection piece 40 is integrated on the non-opening valve 60, and the floating of the non-opening valve 60 can trigger the upper pressure sensing piece 42 to realize the upper pressure detection. The structure can improve the integration of the components in the cover 20.

[0041] In the embodiment, the trigger piece 41 comprises a magnetic piece 411, and the upper pressure sensing piece 42 comprises a magnetic control switch 421. The cooperation of the magnetic piece 411 and the magnetic control switch 421 makes the trigger of the upper pressure detection piece 40 more sensitive, ensures the accuracy of the pressure detection, and improves the cooking safety.

[0042] The magnetic switch 421 can be a reed switch or a Hall sensor.

[0043] like Figure 8 As shown, the temperature detection element 50 includes an NTC 51 mounted on the cover 20. The NTC 51 is connected in series with the pressure sensor 42 and electrically connected to the circuit board of the upper module 32. The use of an NTC (negative temperature coefficient thermistor) enables real-time monitoring of temperature changes inside the cooking appliance. During slow cooking, simmering, and other cooking processes requiring long-term stable temperatures, the NTC provides continuous temperature monitoring to ensure the taste and nutritional value of the food. The series connection between the NTC 51 and the pressure sensor 42 makes the pressure detection of the cooking appliance more accurate. Specifically, based on the sensing of the magnetic switch 421 and the temperature detection of the NTC 51, the software determines that pressure is applied only when both conditions are met, i.e., when the temperature is higher than the preset temperature (normally, pressure is not applied when the temperature is lower than the preset temperature).

[0044] In this embodiment, based on the sensing of the magnetic switch 421 and the detection of the NTC temperature, the software determines that when the temperature is higher than 50°, the pressure will be applied only after both conditions are met (normally, the pressure will not be applied when the temperature is lower than 50°).

[0045] It should be noted that the NTC51 and the upper pressure sensor 42 are connected in series to the same pin of the upper module 32, which simplifies the connection structure.

[0046] like Figure 5 As shown, in this embodiment, the check valve 60 includes a valve body 61, a safety valve core 62, and a spring 63. The valve body 61 has a vent hole 611 extending through it along its axial direction. The safety valve core 62 is movably disposed at the opening of the vent hole 611. One end of the spring 63 abuts against the valve body 61, and the other end of the spring 63 abuts against the safety valve core 62, so that the safety valve core 62 blocks the opening of the vent hole 611. This structural design of the check valve 60 ensures that under normal cooking pressure, the safety valve core 62 can stably block the vent hole 611 to prevent steam leakage. When the pressure rises abnormally, the safety valve core 62 can overcome the spring force and open the vent hole 611 to release excess pressure. This design is particularly crucial in high-pressure cooking appliances, effectively preventing safety accidents caused by excessive pressure.

[0047] In this embodiment, when the pressure inside the pot reaches 140 kPa, the safety valve core 62 can overcome the force of the spring and open the vent 611 to release excess pressure.

[0048] like Figure 2 and Figure 3As shown, the cover 20 further comprises an inner liner 21 located below the face cover 22, the upper pressing sensing member 42 is arranged on the inner liner 21, the inner liner 21 has an avoiding gap 211, the end of the upper pressing sensing member 42 facing the non-return valve 60 is arranged corresponding to the avoiding gap 211, the face cover 22 has an observation hole 221 penetratingly arranged, a cylinder 222 extending downward is arranged around the observation hole 221, the upper end of the non-return valve 60 penetrates the cylinder 222, and the cylinder 222 extends below the avoiding gap 211. Since the inner liner 21 has the avoiding gap 211, and the end of the upper pressing sensing member 42 facing the non-return valve 60 is arranged corresponding to the avoiding gap 211, the avoiding gap 211 can reduce the interference of the inner liner 21 on the upper pressing sensing member 42. For example, the trigger member 41 comprises a magnetic member 411, the upper pressing sensing member 42 comprises a magnetic control switch 421, and the avoiding gap 211 can increase the magnetic flux of the magnetic control switch 421. Moreover, since the cylinder 222 extends below the avoiding gap 211, the cylinder 222 can block the steam at the non-return valve 60, so as to avoid the high-temperature steam directly impacting the magnetic control switch 421.

[0049] In the embodiment, the valve body 61 penetrates the cylinder 222, and the cylinder 222 can play a role of moving guide for the valve body 61.

[0050] In the embodiment, the cover 20 further comprises a steel cover located below the inner liner 21, and the steel cover can play a role of sealing and pressure bearing.

[0051] As shown in the figures, Figure 5 The non-return valve 60 has a mounting groove 64 extending along the circumference of the non-return valve 60, and the magnetic member 411 is an annular magnet embedded in the mounting groove 64. Embedding the annular magnet in the mounting groove 64 can not only ensure the stable position of the magnetic member 411, but also avoid the magnetic member 411 falling off due to high temperature during cooking, thereby improving the durability and safety of the cooking appliance.

[0052] In the embodiment, the magnetic control switch 421 is arranged on one side of the non-return valve 60 in the transverse direction and is spaced apart from the non-return valve 60. Spacing the magnetic control switch 421 apart from the non-return valve 60 can avoid the high-temperature steam directly impacting the magnetic control switch 421 and affecting the normal work of the magnetic control switch 421. Meanwhile, since the magnetic control switch 421 is sensitive to the magnetic field, even if a certain distance is kept from the non-return valve 60, the movement of the magnetic member 411 can be accurately detected, so as to realize the upper pressing detection. In the cooking appliance that needs to monitor the high-pressure environment, such as an electric pressure cooker, this design can ensure the long-term stable work of the magnetic control switch 421 and improve the accuracy and reliability of the pressure detection.

[0053] As shown in the figures, Figure 6As shown, the lateral distance between the magnetic component 411 and the magnetic control switch 421 is D, where 7mm ≤ D ≤ 9mm. By precisely controlling the lateral distance between the magnetic component 411 and the magnetic control switch 421, false triggering caused by excessive distance can be avoided while ensuring detection sensitivity, thus improving the stability and accuracy of the pressure detection component.

[0054] The lateral distance D between the magnetic component 411 and the magnetic switch 421 can be 7mm, 8mm, 9mm, or any other value between 7mm and 9mm. In this embodiment, the lateral distance D between the magnetic component 411 and the magnetic switch 421 is 8mm.

[0055] Furthermore, the longer the lateral distance D between the magnetic component 411 and the magnetic switch 421, the stronger the magnetic field strength of the magnetic component 411 needs to be. The upward movement of the check valve 60 is also affected by the attraction; the stronger the magnetic field, the greater the attraction.

[0056] It should be noted that the lateral distance between the magnetic component 411 and the magnetic switch 421 is the lateral distance between the end face of the magnetic switch 421 and the axis of the magnetic component 411.

[0057] In this embodiment, the pot lid is made of SUS430, and the stop plate is made of SUS304.

[0058] like Figure 6 As shown, the vertical distance between the magnetic component 411 and the magnetic switch 421 is H. When the check valve 60 is in the floating position, 6mm ≤ H < 8mm. When the check valve 60 is in the initial position, 13mm ≤ H ≤ 15mm.

[0059] The on / off sensing distance of the magnetic switch 421 is designed to be >13mm OFF and <8mm ON. When the check valve 60 is in the initial position, the magnetic switch 421 does not sense. When the check valve 60 is in the floating position, the magnetic switch 421 senses (the magnetic switch 421 can sense the magnetic element 411 before the check valve 60 moves to the floating position).

[0060] By controlling the vertical distance between the magnetic component 411 and the magnetic switch 421, accurate triggering of the magnetic switch 421 can be ensured when the check valve 60 floats up, while false triggering of the magnetic switch 421 is avoided when the check valve 60 is in the initial position, thus improving the accuracy and reliability of pressure detection.

[0061] It should be noted that the vertical distance between the magnetic component 411 and the magnetic switch 421 refers to the distance between the upper end of the magnetic component 411 and the axis of the magnetic switch 421.

[0062] When the stop valve 60 is in the floating position, the distance H between the magnetic member 411 and the magnetic switch 421 in the vertical direction can be 6 mm, 7 mm, 8 mm, or any other value between 6 mm and 8 mm. When the stop valve 60 is in the initial position, the distance H between the magnetic member 411 and the magnetic switch 421 in the vertical direction can be 13 mm, 14 mm, 15 mm, or any other value between 13 mm and 15 mm.

[0063] In this embodiment, the distance between the magnetic member 411 and the magnetic switch 421 in the vertical direction is 14.7 mm in the initial position, and no induction occurs. After floating, the distance between the magnetic member 411 and the magnetic switch 421 in the vertical direction is 7.4 mm, and induction occurs before this distance.

[0064] It should be noted that in this embodiment, the vertical direction refers to the up-down direction in Figure 1 , and the horizontal direction refers to the left-right direction in Figure 1 .

[0065] As shown in Figure 7 and Figure 8 , the temperature detection member 50 and the stop valve 60 are arranged in the horizontal direction. The temperature detection member 50 is fixed to the cover 20 by a first bracket, and the stop valve 60 is fixed to the cover 20 by a second bracket. With the above structure, the temperature detection interference can be reduced, and the temperature detection is more accurate, especially at the moment when the stop valve 60 falls down. At this time, external gas may enter the pot, and temperature data needs to be collected. The temperature detection member 50 is farther away from the stop valve 60, and the temperature detection accuracy is better.

[0066] In this embodiment, the upper module 32 and the lower module 31 are arranged opposite to each other in the circumferential direction of the cover 20 to detect the opening and closing of the cover. The relative arrangement (wireless coil induction) of the upper module 32 and the lower module 31 can ensure that the upper module 32 and the lower module 31 can be accurately aligned when the cover 20 is closed, and the wireless connection is performed to realize the opening and closing detection of the cover.

[0067] Specifically, the upper module 32 with a plastic shell is installed in the module groove of the inner liner 21 and is fixed by a buckle. The lower module 31 is installed on the corresponding position of the middle plate 11. The NTC and the magnetic switch are fixed to the inner liner 21.

[0068] The cooking appliance includes an electric pressure cooker and a multifunctional pot with a pressure cooking function.
