Technical Field

[0001] The invention relates to the technical field of electric stew pots, in particular to a temperature control mechanism based on temperature sensing technology and an electric stew pot thereof. Background Art

[0002] An electric stew pot is a kitchen appliance that uses electric heating to cook. It usually has functions such as slow cooking and heat preservation, and is suitable for stewing various ingredients, such as meat, beans, soups, etc. Its working principle is to convert electrical energy into heat energy through the built-in heating element, thereby heating the ingredients in the pot. The design of an electric stew pot usually focuses on the heat preservation effect and the control of cooking time to ensure that the ingredients can be fully stewed to achieve a delicious taste and rich nutrition.

The electric stew pot and its heating plate provided by the present invention use the graphene heating layer as the heating element, and propose a new heating scheme for the electric stew pot product, which can greatly improve the heat utilization efficiency of the electric stew pot, and simplify the structure of the heating component.

The heating mechanism 4 includes a slide groove plate 41, and the bottom annular array of the slide groove plate 41 is provided with a slide groove plate slide groove 42. The bottom annular array of the slide groove plate 41 is fixedly connected with a slide groove plate support rod 43. The bottoms of the multiple slide groove plate support rods 43 are respectively fixedly connected to the top of the connecting plate 31 in an annular array. The middle part of the bottom of the slide groove plate 41 is rotatably connected with a turntable 44. The inner wall of the turntable 44 is fixedly connected to the top of the outer wall of the rotating rod 36, and the bottom annular array of the turntable 44 is provided with an arc-shaped slide groove 45.The inner walls of the plurality of chute plate chutes 42 are slidably connected with T-shaped expansion rods 46, the inner sides of the bottoms of the plurality of T-shaped expansion rods 46 are fixedly connected with columnar sliders 47, the outer walls of the plurality of columnar sliders 47 are respectively slidably connected to the inner walls of the plurality of arc-shaped chutes 45 opened on the turntable 44, the outer sides of the plurality of T-shaped expansion rods 46 are fixedly connected with heating plates 48, the outer bottoms of the plurality of heating plates 48 are fixedly connected with control circuit fixing plates 410, the middle parts of the outer sides of the plurality of heating plates 48 are fixedly connected with a plurality of heating plate control circuits 49, and the ends of the plurality of groups of heating plate control circuits 49 away from the heating plates 48 are respectively fixedly connected to the top of the control chassis 2 in a circular array through the inner walls of the control circuit fixing plates 410;

[0035] When the electric stew pot 1 is needed for steaming, firstly, the ingredients are put into the inner wall of the inner pot 6 and a proper amount of water is added, and then the inner pot 6 is placed on the top of the slide plate 41. At this time, the control plate 33 is started. After the control plate 33 is started, the transmission rotating rod 36 rotates, and the rotating rod 36 rotates to drive the turntable 44 to rotate. The turntable 44 rotates through the arc-shaped slide groove 45 provided to push the columnar slider 47 to slide on the inner wall of the arc-shaped slide groove 45, so that the multiple T-shaped expansion rods 46 slide on the inner wall of the slide groove 42 of the slide plate, and then the multiple T-shaped expansion rods 46 push the heating plates 48 to expand, and the multiple heating plates 48 move inward so that the inner sides are attached to the surface of the inner pot 6, so that the inner pot is evenly heated;

[0036] At the same time, when the rotating rod 36 rotates, the bottom gear plate 34 rotates accordingly, and the bottom gear plate 34 rotates and meshes with multiple gears 354, so that multiple gear rotating rods 355 rotate, and the gear rotating rod 355 rotates to drive the second gear 356 to rotate, and the second gear 356 rotates and meshes with two rack rods 358. The two rack rods 358 slide on the inner sides of the two sliding groove rods 352, thereby causing the two expansion plates 357 to expand and contract. When the multiple groups of expansion plates 357 move inward, they drive the multiple groups of rotating rods 3510 to rotate, and the lifting push rod 3512 is pushed up or down by the rotation angle of the rotating rod 3510 and the push block 3511. The rise or fall of the lifting push rod 3512 drives the lifting The rod 3513 slides in the lifting rod slide slot rod 3515, thereby driving the induction coil 3514 to stick to the bottom of the inner pot 6. As the temperature rises or falls, the induction coil 3514 transmits a signal to the temperature receiving component 353 through the induction coil line 3516. After receiving the signal, the temperature receiving component 353 performs corresponding temperature control operations. If the temperature is too high, the temperature receiving component 353 sends an instruction through the control chassis 2 so that the heating plate control circuit 49 of one or more heating plates 48 no longer receives power, thereby stopping the corresponding heating plate 48 from heating. If the temperature is too low, the temperature receiving component 353 sends an instruction through the control chassis 2 so that one or more heating plates 48 stop heating. The heating plate control circuit 49 of 48 receives power, so that the corresponding heating plate 48 performs heating operation. In this way, through the cooperation of multiple heating plates 48, the inner pot 6 can be heated evenly and efficiently, and the steaming effect and taste of food can be improved. At the same time, the real-time temperature monitoring of the induction coil 3514 and the intelligent temperature control of the temperature receiving component 353 enable the electric stew pot 1 to always maintain a suitable temperature during the steaming process, avoiding the loss of nutrition and the deterioration of taste caused by excessively high or low temperature of the food, and improving the quality and taste of the steamed food. In addition, the temperature is detected by multiple induction coils 3514, so that the temperature control is more accurate and stable. Each induction coil 3514 works independently. Once the temperature of a certain area is abnormal, the temperature receiving component 353 can respond quickly and accurately adjust the working state of the heating plate 48 in the corresponding area by controlling the chassis 2 to ensure that the temperature of the entire inner pot 6 is evenly distributed. This refined temperature control method not only improves the efficiency of steaming and stewing food, but also further ensures the nutrition and taste of the food. In addition, since the temperature is detected simultaneously by multiple induction coils 3514, when the accuracy and stability are reduced under long-term high-temperature working environment, it can also be supplemented and corrected by other normally working induction coils 3514, thereby ensuring the continuous accuracy and stability of temperature control.

[0037] See also Figure 9-10, both of the two pot lid control mechanisms 5 include rectangular connection frames 51. The inner sides of the two rectangular connection frames 51 are respectively fixedly connected to the outer tops of two of the heating plates 48. In the middle of the bottoms of the two rectangular connection frames 51, there are fixedly connected motor connection bins 52. At the bottoms of the inner walls of the two motor connection bins 52, there are fixedly connected motors 53. The output ends of the two motors 53 are both fixedly connected to lead screws 54. The tops of the two lead screws 54 both extend to the outer tops of the rectangular connection frames 51. On one side of the inner walls of the rectangular connection frames 51, the outer walls of the two lead screws 54 are both threadedly connected to transmission plates 510. On both sides of the tops of the two transmission plates 510, there are fixedly connected push rods 55. The outer walls of the two transmission plates 510 are both slidably connected to the inner walls of the rectangular connection frames 51. The tops of the two groups of push rods 55 both extend to the outer tops of the rectangular connection frames 51 and are both fixedly connected to lifting plates 57. On the left and right sides of the tops of the two rectangular connection frames 51, there are fixedly connected L-shaped side plates 56. On the tops of the two lifting plates 57, there are fixedly connected lifting vertical plates 58. The outer walls of the two lifting vertical plates 58 are both slidably connected to the inner sides of the two L-shaped side plates 56. On the tops of the two lifting vertical plates 58, there are rotatably connected push discs 59;

[0038] When there is a large amount of steam inside the inner pot 6, the pressure relief valve of the pot lid 7 alone can no longer meet the requirement of rapid pressure relief. At this time, the motor 53 can be started. The output end of the motor 53 drives the lead screw 54 to rotate. During the rotation of the lead screw 54, it drives the transmission plate 510 to move up and down. During the movement of the transmission plate 510, it pushes the lifting plate 57 to move up and down through the push rod 55. During the up and down movement of the lifting plate 57, it drives the push disc 59 to rotate through the lifting vertical plate 58. During the rotation of the push disc 59, it can push the pot lid 7 open. During the process of the pot lid 7 being pushed open, it can rapidly relieve pressure through the pressure relief valve, avoiding the phenomenon that the inner pot 6 is damaged due to excessive internal pressure.

[0039] Working principle: when the electric stew pot 1 is needed for steaming, first put the ingredients into the inner wall of the inner pot 6 and add an appropriate amount of water, then place the inner pot 6 on the top of the slide plate 41, at this time, start the control plate 33, and after the control plate 33 is started, the transmission rotating rod 36 rotates, and the rotating rod 36 rotates to drive the turntable 44 to rotate, and the turntable 44 rotates through the arc-shaped slide groove 45 provided to push the columnar slider 47 to slide on the inner wall of the arc-shaped slide groove 45, so that the multiple T-shaped expansion rods 46 slide on the inner wall of the slide groove 42 of the slide plate, and then the multiple T-shaped expansion rods 46 push the heating plates 48 to expand, and the multiple heating plates 48 move inward so that their inner sides are attached to the surface of the inner pot 6, so that the inner pot is evenly heated. At the same time, when the rotating rod 36 rotates The bottom gear plate 34 rotates accordingly, and the bottom gear plate 34 rotates and meshes with the multiple gears 354, so that the multiple gear rotating rods 355 rotate, and the gear rotating rod 355 rotates to drive the second gear 356 to rotate, and the second gear 356 rotates and meshes with the two rack rods 358, and the two rack rods 358 slide inside the two slide slot rods 352, so that the two expansion plates 357 are expanded and contracted, and when the multiple groups of expansion plates 357 move inward, they drive the multiple groups of rotating rods 3510 to rotate, and the lifting push rod 3512 is pushed up or down by the rotation angle of the rotating rod 3510 and the push block 3511, and the lifting push rod 3512 is lifted or lowered. The lifting or lowering of the lifting push rod 3512 drives the lifting rod 3513 to slide in the lifting rod slide slot rod 3515, thereby driving the induction coil 3514 to stick to the inner pot 6 At the bottom of the pot 6, as the temperature rises or falls, the induction coil 3514 transmits a signal to the temperature receiving component 353 through the induction coil circuit 3516. After receiving the signal, the temperature receiving component 353 performs a corresponding temperature control operation. If the temperature is too high, the temperature receiving component 353 sends an instruction through the control chassis 2 so that the heating plate control circuit 49 of one or more heating plates 48 no longer receives power, thereby causing the corresponding heating plate 48 to stop heating. If the temperature is too low, the temperature receiving component 353 sends an instruction through the control chassis 2 so that the heating plate control circuit 49 of one or more heating plates 48 receives power, thereby causing the corresponding heating plate 48 to perform a heating operation. In this way, through the mutual cooperation of multiple heating plates 48, the uniform temperature of the inner pot 6 can be achieved. The uniform and efficient heating improves the steaming and stewing effect and taste of food. At the same time, the real-time temperature monitoring of the induction coil 3514 and the intelligent temperature control of the temperature receiving component 353 enable the electric stew pot 1 to always maintain a suitable temperature during the steaming and stewing process, avoiding the loss of nutrition and the deterioration of the taste of the food due to excessively high or low temperature, thereby improving the quality and taste of the steamed and stewed food. In addition, the temperature is detected by multiple induction coils 3514, so that the temperature control is more accurate and stable. Each induction coil 3514 works independently. Once the temperature of a certain area is abnormal, the temperature receiving component 353 can respond quickly, and accurately adjust the working state of the heating plate 48 in the corresponding area by controlling the chassis 2 to ensure that the temperature distribution of the entire inner pot 6 is uniform.

[0040] When a large amount of steam appears inside the inner pot 6, the need for rapid pressure relief can no longer be met by the pressure relief valve of the pot cover 7 alone. At this time, the motor 53 can be started, and the output end of the motor 53 drives the screw rod 54 to rotate. The screw rod 54 drives the transmission plate 510 to move up and down during the rotation. The transmission plate 510 pushes the lifting plate 57 to move up and down through the push rod 55 during the movement.
