Description

Technical Field

[0001] This utility model relates to the field of anti-dry-burning smart stoves, specifically an infrared anti-dry-burning smart stove. Background Technology

[0002] As a core cooking appliance in home kitchens and restaurants, cooktops are used frequently and widely, and are closely related to energy consumption and safety. With the deepening of the concept of energy conservation and emission reduction and the rapid development of smart home appliance technology, the shortcomings of traditional cooktops in terms of energy efficiency and safety protection performance have become increasingly prominent, making it difficult to meet the needs of modern users for efficient, safe, and intelligent cooking equipment. Currently, most traditional stoves on the market rely on users manually operating knobs to control the gas supply. Therefore, if users are careless, such as forgetting to turn off the gas, leaving the kitchen temporarily, children accidentally turning it on, or pots and pans being moved, it is very easy to cause an accident of burning without a pot. In the case of burning without a pot, the stove flame continues to heat the stove surface and surrounding components. On the one hand, this will cause a large amount of natural gas or liquefied petroleum gas to be wasted, resulting in energy waste. On the other hand, the high temperature will accelerate the aging and damage of components such as the stove surface and burner cap, shortening the life of the stove. In more serious cases, it may cause the stove surface to crack, gas pipes to deform and leak due to heat, or even induce major safety accidents such as fires and explosions, posing a serious threat to the personal and property safety of users. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide an infrared anti-dry-burning smart stove to solve the technical problems of traditional stoves that rely on manual control and lack an active detection and intelligent intervention mechanism for the presence of pots and the state of dry burning without pots, which leads to energy waste, accelerated aging of stove components, and safety hazards such as gas leakage and fire caused by dry burning without pots.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] An infrared anti-dry-burning smart stove, such as Figure 1-4 As shown, the stove 1 includes a stove platform 101 and a stove surface 102. The top rear end of the stove surface 102 has two mounting slots 106. The mounting slots 106 have screw holes 107 inside. The bottom of the stove surface 102 has two tightening slots 108. The two tightening slots 108 are in the same position as the mounting slots 106, and the screw holes 107 pass through the mounting slots 106 and the tightening slots 108. An anti-dry-burning mechanism 2 is installed in the mounting slot 106. The anti-dry-burning mechanism 2 includes a mounting block 201. A screw 208 is provided at the bottom of the mounting block 201. The mounting block 201 is adapted to the mounting slot 106, and the screw 208 is inserted into the screw hole 107. The anti-dry-burning mechanism 2 is fixedly connected to the stove 1 in the tightening slot 108 by a tightening mechanism 3. The top of the mounting block 201 is rotatably connected to the mounting column 204 through a rotating seat 203. Multiple infrared temperature sensors 205 are installed at equal intervals from top to bottom on the outer surface of the mounting column 204. A natural gas detection sensor 206 is provided on the lower part of the outer surface of the mounting column 204. The stove surface 102 of the stove 1 has a mounting slot 106, a screw hole 107, and a tightening slot 108. The mounting block 201 of the anti-dry-burning mechanism 2 is adapted to the mounting slot 106. After the screw 208 is inserted into the screw hole 107, it is fixed by the tightening mechanism 3. The structure has strong adaptability and is easy to disassemble and assemble. The rotating seat 203 of the mounting block 201 allows the mounting column 204 to be flexibly adjusted in angle. Multiple infrared temperature sensors 205 can fully cover the detection area, and the natural gas detection sensor 206 below supplements the gas monitoring, realizing dual protection against dry burning and gas leakage, improving safety and adaptability.

[0025] See Figure 1 , Figure 2 , Figure 3 , Figure 4 An integrated wiring harness 207 is provided on the back of the mounting post 204, and a sealing plate 202 for sealing the mounting groove 106 is provided on the outside of the mounting block 201. The sealing plate 202 is in close contact with the cooktop surface 102. The integrated wiring harness 207 on the back of the mounting post 204 integrates the wiring of multiple infrared temperature sensors 205 and natural gas detection sensors 206, avoiding messy wiring, reducing signal interference, and ensuring stable electrical connection between the sensors and the main control board inside the cooktop 1. The sealing plate 202 on the outside of the mounting block 201 is in close contact with the cooktop surface 102, sealing the mounting groove 106. At the same time, the sealing structure at the joint between the sealing plate 201 and the mounting groove 106 strengthens the protection, effectively preventing cooking oil and cleaning moisture from entering, protecting components such as the screw hole 107 inside the mounting groove 106 from corrosion, and ensuring the stable operation of the anti-dry burning mechanism 2.

[0026] See Figure 3 , Figure 4The tightening mechanism 3 includes a threaded ring 301, which is adapted to the tightening groove 108 and screwed to the screw 208. Two tightening plates 302 are provided at the bottom of the threaded ring 301 for manual rotation. The threaded ring 301 of the tightening mechanism 3 precisely matches the tightening groove 108 of the cooktop 102 and is screwed to the screw 208 of the anti-dry-burning mechanism 2, ensuring a stable connection. The design of the two tightening plates 302 at the bottom of the threaded ring 301 allows users to directly rotate it manually without the need for special tools, thus enabling the fixing or disassembly of the anti-dry-burning mechanism 2 and the cooktop 1, simplifying the installation process and reducing the difficulty and cost of later maintenance.

[0027] See Figure 1 , Figure 4 Both the anti-dry-burning mechanism 2 and the tightening mechanism 3 are made of stainless steel. Stainless steel inherently possesses excellent corrosion resistance, protecting the mechanism from grease and moisture generated during cooking and cleaning. Simultaneously, stainless steel exhibits excellent high-temperature resistance, adapting to the high-temperature environment surrounding the burner cap 104 during stove use, preventing deformation due to high temperatures. The combination of these two characteristics ensures the structural strength and stability of the mechanism, extending its overall service life.

[0028] See Figure 3 , Figure 4 The stove 101 has a cooktop 102 on top, with two burner caps 104 in the center of the top. Two cooktop supports 105 are located on the outer sides of the burner caps 104. The top of the stove 101 supports the cooktop 102, providing a stable foundation for all components on the cooktop 102 and ensuring the overall structural stability of the stove 1. The two burner caps 104 in the center of the top of the cooktop 102 serve as the core combustion components. The two cooktop supports 105 on their outer sides stably support the cookware, ensuring the bottom of the cookware is precisely aligned with the combustion area of ​​the burner caps 104, guaranteeing efficient heat transfer and improving cooking efficiency. The cooktop supports 105 also prevent the cookware from directly contacting the burner caps 104 and causing damage.

[0029] See Figure 1 , Figure 2The cooktop 102 has two knobs 103 at its top front end, each equipped with a pointer. These knobs correspond one-to-one with the two burner caps 104 in the center of the cooktop 102. Users can independently control the gas supply and flame intensity of the corresponding burner cap 104 using a single knob 103, meeting the flame requirements of different cooking scenarios and offering flexible operation. The pointers on the knobs 103 accurately point to the power level markings on the cooktop 102, allowing users to intuitively determine the current flame level or on / off status. This effectively avoids errors in flame adjustment due to unclear settings or forgetting to turn off the gas, improving convenience and safety.

[0030] See Figure 3 , Figure 4 Multiple infrared temperature sensors 205 and natural gas detection sensors 206 are electrically connected to the main control board inside the cooktop 1 via an integrated wiring harness 207. The main control board is configured to control the gas supply based on the received sensor signals. A stable electrical connection is established between the multiple infrared temperature sensors 205 and the natural gas detection sensors 206 and the main control board inside the cooktop 1 via the integrated wiring harness 207, ensuring that signals such as the cookware status, temperature, and gas concentration detected by the sensors are quickly transmitted to the main control board. The main control board has preset judgment logic; upon receiving signals, it can quickly identify abnormal states such as empty cooking without a pot or gas leakage, and promptly cut off the gas supply. During normal cooking, it maintains the gas supply, achieving intelligent and precise control of the gas supply, avoiding the lag of manual control, and significantly improving the safety and intelligence level of the cooktop.

[0031] See Figure 1 , Figure 4 A sealing structure is provided at the joint between the sealing plate 202 and the mounting groove 106 to prevent oil and moisture from entering the mounting groove. This sealing structure, after the sealing plate 202 adheres to the cooktop surface 102 and seals the mounting groove 106, further fills the gaps between them, enhancing the sealing performance. This structure effectively prevents oil, soup, and moisture generated during cooking, as well as moisture from cleaning the cooktop, from entering the mounting groove 106. It also prevents corrosion of components such as the screw hole 107 and screw 208 within the groove, which could lead to jamming or loosening, ensuring the installation stability of the anti-dry-burning mechanism 2 and guaranteeing its long-term reliable operation.

[0032] The implementation principle of this embodiment is as follows: First, the assembly and fixing of each component is completed. The mounting block 201 of the anti-dry burning mechanism 2 is placed into the mounting groove 106 of the cooktop 102, so that the screw 208 at the bottom of the mounting block 201 is inserted into the screw hole 107 in the mounting groove 106. The screw 208 extends through the screw hole 107 to the tightening groove 108 at the bottom of the cooktop 102. The threaded ring 301 of the tightening mechanism 3 is placed into the tightening groove 108. By rotating the tightening plate 302, the threaded ring 301 is screwed and tightened with the screw 208, thereby fixing the anti-dry burning mechanism 2 to the cooktop 1. At the same time, the sealing plate 202 on the outside of the mounting block 201 is attached to the cooktop 102, and the sealing structure at the joint prevents oil and water vapor from entering the mounting groove 106. Next, adjust the detection angle according to the usage requirements. Rotate the mounting column 204 by rotating the rotating seat 203 on the top of the mounting block 201 so that the multiple infrared temperature sensors 205 above the outer surface of the mounting column 204 are aligned with the stove rack 105 area, and the natural gas detection sensor 206 below is in a suitable detection position around the stove 1. The electrical connection between the sensor and the main control board inside the stove 1 is completed by the integrated wiring harness 207. In use, the ignition is operated by the knob 103 on the cooktop 102. After the pot is placed on the cooktop rack 105, the infrared temperature sensor 205 detects the temperature of the area and the presence of the pot in real time, and the natural gas detection sensor 206 detects gas leakage in real time. The signals from both types of sensors are transmitted to the main control board via the integrated wiring harness 207. When the infrared temperature sensor 205 detects that there is no pot and the temperature is abnormally high, or when the natural gas detection sensor 206 detects a gas leak, the main control board immediately cuts off the gas supply. During normal cooking, the main control board maintains the gas supply, realizing intelligent protection against dry burning and gas leakage. The dry burning prevention mechanism 2 and the tightening mechanism 3 are made of stainless steel to ensure structural durability.
