[0002] As a clean energy kitchen appliance that replaces traditional gas stoves, electric stoves use infrared composite technology with an alloy heating element embedded in a microcrystalline glass panel, and are combined with an LED optical layer to simulate flame patterns. While taking into account the compatibility with various cookware materials, they provide a gas stove-like user experience.

[0003] The existing electric stove structure mainly includes a stove stand, on which pots and pans are placed and the electric stove can be used for cooking. However, current electric stoves have difficulty detecting dry burning of pots and pans and cannot take measures to deal with dry burning. Dry burning refers to the drying out of the water in the pot. Continuing to heat the pot will cause its temperature to rise sharply, which will cause great safety hazards. Summary of the Invention

[0004] To address the problem that current electric stoves in the background art are unable to detect dry burning of pots and cannot take countermeasures against dry burning, this invention proposes an intelligent anti-dry burning household electric stove.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent anti-dry-burning household electric stove, comprising a stove body and a stove support, and further comprising:

[0006] Temperature monitoring component, which is installed on the main body of the electric stove and located on one side of the stove support, is used to monitor the temperature of the bottom of the pot in real time.

[0007] The lifting assembly is mounted on the stove support and is used to lift the pot off the stove support.

[0008] Furthermore, the temperature monitoring component includes a mounting block disposed on the main body of the electric stove, a non-contact infrared sensor disposed inside the mounting block, the non-contact infrared sensor being directly above the stove support, and a rotating shaft being fixedly connected to the bottom of the mounting block, the rotating shaft being rotatably connected to the main body of the electric stove.

[0009] Furthermore, a motor is installed inside the main body of the electric stove, and a circular gear is fixedly connected to the output shaft of the motor. A cavity is opened inside the main body of the electric stove, and a rotating ring is rotatably connected inside the cavity. An annular gear that meshes with the circular gear is fixedly connected to the outer wall of the rotating ring.

A spring is fixedly connected between the stop block and the inner wall of the fixed box. An electromagnet is fixedly connected to both the stop block and the inner wall of the fixed box. A rotating plate is fixedly connected to the outer wall of the rotating shaft, and a gap is provided between the two stop blocks. The rotating plate is directly opposite the gap.

[0010] Furthermore, the lifting assembly includes an electric push rod fixed to the main body of the electric stove, a connecting plate fixed to the output end of the electric push rod, a connecting ring fixed to the connecting plate, and a top column fixed to the connecting ring via a connecting block. The top column is slidably inserted into the stove support.

[0011] Furthermore, a support block is installed on the mounting block, and an alarm light and a buzzer are installed on the main body of the electric stove.

[0012] Furthermore, multiple drain strips are fixedly connected to the stove support, an annular collection groove is provided on the stove support, and an inclined slide is fixedly connected to the main body of the electric stove.

[0015] The technical effects and advantages of this invention: a smart anti-dry-burning household electric stove.

[0016] (1) By setting up a temperature monitoring component, when cooking on the stove, the pot is placed on the stove support and the non-contact infrared sensor is aimed at the bottom of the pot. The temperature of the bottom of the pot can be monitored in real time. When the pot is dry-burning, the temperature of the pot will rise sharply in a very short time, which is different from the temperature when cooking on the stove normally. The non-contact infrared sensor transmits the real-time information of the bottom temperature of the pot to the system. The system will take countermeasures by activating the lifting component.

[0017] (2) By setting up the lifting component, when the system determines that the pot is dry-burning, it first turns off the flame in the stove to prevent the pot from continuing to dry-burning. At the same time, it starts the electric push rod. The electric push rod drives the connecting plate and the connecting ring to move upward. The connecting ring can drive the four top columns to move upward at the same time. The top columns can lift the pot, so that the bottom of the pot leaves the stove support, thereby allowing air to enter between the stove support and the pot, accelerating the cooling of the pot.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figures 1-7 A smart anti-dry-burning household electric stove includes a stove body 1 and a stove support 2, and also includes:

[0029] Temperature monitoring component, which is installed on the main body 1 of the electric stove and located on one side of the stove support 2, is used to monitor the temperature of the bottom of the pot in real time.

[0030] The lifting assembly is mounted on the stove support 2 and is used to lift the pot off the stove support 2.

[0031] When in use, place the pot on the stove support 2 and heat the pot by igniting the electric stove body 1. The temperature monitoring component can monitor the temperature of the bottom of the pot in real time. During normal cooking, the temperature of the bottom of the pot rises normally. When the pot becomes dry-burned, the water in the pot is burned off, and the temperature of the bottom of the pot rises rapidly in a very short time. After detecting dry burning, the lifting component is activated, which can lift the pot and accelerate the cooling of the pot.

[0032] Reference Figure 1 and Figure 2 The temperature monitoring component includes a mounting block 3 installed on the main body 1 of the electric stove. A non-contact infrared sensor 4 is installed inside the mounting block 3. The non-contact infrared sensor 4 is directly above the stove support 2. A rotating shaft 5 is fixed to the bottom of the mounting block 3 and is rotatably connected to the main body 1 of the electric stove. After the pot is placed on the stove support 2, the detection head of the non-contact infrared sensor 4 is directly facing the bottom of the pot. During cooking, the non-contact infrared sensor 4 can monitor the temperature of the pot in real time. By setting the rotating shaft 5, the mounting block 3 can be pointed at other locations in the kitchen when not cooking, such as locations prone to fire, thereby realizing the function of fire early warning.

[0033] Reference Figure 2 , Figure 3 and Figure 4The electric stove body 1 houses a motor 6, with a circular gear 7 fixedly connected to the output shaft of the motor 6. A cavity 8 is formed within the electric stove body 1, and a rotating ring 9 is rotatably connected within the cavity 8. A ring gear 10, meshing with the circular gear 7, is fixedly connected to the outer wall of the rotating ring 9. Two fixed boxes 11 are fixedly connected to the inner wall of the rotating ring 9, with a stop block 12 slidably inserted within each fixed box 11. A spring 13 is fixedly connected between the stop block 12 and the inner wall of the fixed box 11. Electromagnets 14 are fixedly connected to both the stop block 12 and the inner wall of the fixed box 11. A rotating plate 15 is fixedly connected to the outer wall of the rotating shaft 5, with a gap between the two stop blocks 12 and the rotating plate 15 aligned with the gap. When not cooking, rotating the mounting block 3 causes the non-contact infrared sensor 4 to be aligned with other positions in the kitchen, driving the rotating shaft 5 to rotate. When cooking is required, the non-contact infrared sensor 4 facing other positions needs to be aligned with the bottom of the pot, energizing one of the electromagnets 14. The repulsive force generated between the two can push one of the stop blocks 12 to move, the spring 13 is stretched, the motor 6 is started, the motor 6 drives the spur gear 7 to rotate, the spur gear 7 rotates through the ring gear 10, the ring gear 10 drives the rotating ring 9 to rotate, the rotating ring 9 drives the fixed box 11 and the stop block 12 to rotate. During the rotation, the extended stop block 12 will contact the rotating plate 15 and drive the rotating plate 15 and the rotating shaft 5 to rotate. The stop block 12 stops after rotating one revolution, so that the electromagnet 14 on the other side is energized, so that the other stop block 12 extends. The two stop blocks 12 can clamp and limit the rotating plate 15 in the middle gap. At this time, the non-contact infrared sensor 4 is facing the bottom of the pot, realizing the purpose of resetting the non-contact infrared sensor 4. When it is necessary to freely rotate the mounting block 3 and the non-contact infrared sensor 4, the electromagnet 14 is de-energized. Under the action of the spring 13, the stop block 12 is reset and no longer limits the rotating plate 15. The mounting block 3 can then rotate freely.

[0034] Reference Figure 5 and Figure 6 The lifting assembly includes an electric push rod 16 fixed to the main body 1 of the electric stove. A connecting plate 17 is fixed to the output end of the electric push rod 16. A connecting ring 18 is fixed to the connecting plate 17. A top column 19 is fixed to the connecting ring 18 through a connecting block. The top column 19 is slidably inserted into the stove support 2. When the pot is dry-burning, the gas supply to the main body 1 of the electric stove is turned off, and the electric push rod 16 is activated. The electric push rod 16 drives the connecting plate 17 to move upward. The connecting plate 17 drives the connecting ring 18 to move upward. The connecting ring 18 drives the four top columns 19 to move upward. The top columns 19 can lift the pot, so that the pot is away from the stove support 2. A gap is created between the pot and the stove support 2. Air can enter between the stove support 2 and the pot through the gap, accelerating the cooling of the pot.

[0035] Reference Figure 1 and Figure 2A support block 20 is installed on the mounting block 3, and an alarm light 21 and a buzzer 22 are installed on the main body 1 of the electric stove. By setting the support block 20, kitchen utensils such as spatulas can be supported on the support block 20. By setting the alarm light 21 and the buzzer 22, when the pot is dry-burning, it is necessary not only to turn off the gas of the main body 1 of the electric stove, but also to activate the alarm light 21 and the buzzer 22 to serve as a reminder.

[0036] Reference Figure 1 , Figure 5 and Figure 7 Multiple drain strips 23 are fixedly connected to the stove support 2, and an annular collection groove 24 is opened on the stove support 2. An inclined slide 25 is fixedly connected to the electric stove body 1. One end of the inclined slide 25 is connected to the collection groove 24 through a notch, and the other end of the inclined slide 25 is provided with a collection box 26. When the liquid in the pot overflows during cooking, the liquid will flow down the pot wall to the side wall of the stove support 2 and the drain strips 23. The liquid will be guided into the collection groove 24. The liquid in the collection groove 24 is collected into the collection box 26 through the inclined slide 25, thus realizing the collection of overflow liquid.

[0037] Reference Figure 7 The electric stove body 1 has a circular groove 27, and a collection box 26 is placed in the circular groove 27. A crossbar 28 is provided on the top of the collection box 26, and two rubber blocks 29 are fixed to the bottom of the crossbar 28. The rubber blocks 29 are placed between the collection box 26 and the circular groove 27. When it is necessary to deal with the liquid in the collection box 26, the crossbar 28 is pulled to pull out the rubber blocks 29, and the collection box 26 can be taken out from the circular groove 27. After the liquid is dealt with, the collection box 26 is put back into the circular groove 27, and the rubber blocks 29 are inserted between the collection box 26 and the circular groove 27 to press them together and fix the collection box 26.

[0038] The main body 1 of the electric stove is equipped with a main controller. The non-contact infrared sensor 4, the alarm light 21 and the buzzer 22 are all electrically connected to the main controller. The main controller can control the opening and closing of the lifting component. The main controller can receive signals from the non-contact infrared sensor 4. The main controller can determine whether it is in a dry-burning state and can control the start of the lifting component, the alarm light 21 and the buzzer 22.

[0039] Working principle: When in use, place the pot on the stove support 2, and heat the pot by igniting the electric stove body 1. The temperature monitoring component can monitor the temperature of the bottom of the pot in real time. During normal cooking, the temperature of the bottom of the pot rises normally. When the pot becomes dry, the water in the pot is dried up, and the temperature of the bottom of the pot rises rapidly in a very short time. After detecting dry burning, the lifting component is activated, which can lift the pot and accelerate the cooling of the pot.

[0040] After placing the cookware on the stove support 2, the detection head of the non-contact infrared sensor 4 is facing the bottom of the cookware. During cooking, the non-contact infrared sensor 4 can monitor the temperature of the cookware in real time. By setting the rotating shaft 5, the mounting block 3 can be aimed at other locations in the kitchen when not cooking, such as locations prone to fire, thereby realizing the function of fire early warning.

[0041] When not cooking, rotating mounting block 3 aligns the non-contact infrared sensor 4 with other locations in the kitchen. Mounting block 3 drives the rotating shaft 5 to rotate. When cooking is required, the non-contact infrared sensor 4 facing other locations needs to be aligned with the bottom of the pot, energizing one of the electromagnets 14. The repulsive force between the electromagnets 14 pushes one of the stop blocks 12 to move, stretching the spring 13 and activating the motor 6. The motor 6 drives the sprocket 7 to rotate, which in turn rotates through the ring gear 10. The ring gear 10 drives the rotating ring 9 to rotate, which in turn drives the fixed box 11 and the stop block 12 to rotate. The extended stop block 12... During rotation, it will contact the rotating plate 15 and drive the rotating plate 15 and the rotating shaft 5 to rotate. The stop block 12 will stop after rotating one revolution, which will energize the electromagnet 14 on the other side and cause the other stop block 12 to extend. The two stop blocks 12 can clamp and limit the rotating plate 15 in the middle gap. At this time, the non-contact infrared sensor 4 is facing the bottom of the pot, realizing the purpose of resetting the non-contact infrared sensor 4. When it is necessary to freely rotate the mounting block 3 and the non-contact infrared sensor 4, the electromagnet 14 will be de-energized. Under the action of the spring 13, the stop block 12 will be reset and will no longer limit the rotating plate 15. The mounting block 3 can then rotate freely.

[0042] When the pot becomes dry-burning, turn off the gas supply to the main body 1 of the electric stove and start the electric push rod 16. The electric push rod 16 drives the connecting plate 17 to move upward, the connecting plate 17 drives the connecting ring 18 to move upward, and the connecting ring 18 drives the four top columns 19 to move upward. The top columns 19 can lift the pot, so that the pot is away from the stove support 2. A gap is created between the pot and the stove support 2, and air can enter between the stove support 2 and the pot through the gap, which accelerates the cooling of the pot.

[0043] By setting up the support block 20, kitchen utensils such as spatulas can be supported on the support block 20. By setting up the alarm light 21 and the buzzer 22, when the pot is dry-burning, it is necessary not only to turn off the gas of the electric stove body 1, but also to activate the alarm light 21 and the buzzer 22 to serve as a reminder.

[0044] When liquid overflows from the pot during cooking, it flows down the pot wall onto the side wall of the stove support 2 and the drain strip 23. The liquid is then guided into the collection tank 24, and the liquid in the collection tank 24 is collected into the collection box 26 through the inclined slide 25, thus collecting the overflow liquid.

[0045] When it is necessary to process the liquid in the collection box 26, pull the crossbar 28 to pull out the rubber block 29, and the collection box 26 can be taken out from the round groove 27. After processing, put the collection box 26 into the round groove 27, insert the rubber block 29 between the collection box 26 and the round groove 27 to press it together and fix the collection box 26.

[0046] The main controller can receive signals from the non-contact infrared sensor 4. The main controller can determine whether it is in a dry-burning state and can control the start of the lifting assembly, alarm light 21 and buzzer 22.
