Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliances and intelligent control technology, specifically a dual-temperature control anti-sticking constant temperature control device. Background Technology

[0002] In the design and manufacture of cooking equipment, the temperature control performance of cookware is one of the important indicators for measuring the practicality and safety of the equipment. At present, some anti-sticking cookware based on single temperature control or constant temperature heating technology has appeared on the market. However, these devices usually cannot balance heating efficiency and temperature uniformity. In addition, these devices are prone to sticking or burning due to local overheating during long-term use.

[0003] For example, some existing thermostatic control devices detect the pot's temperature using a single sensor and adjust the heating power using a simple feedback mechanism. Their structural design includes a pot body, a heating plate, and a temperature control module installed at the bottom. This module contains a metal spring and a temperature-sensing element connected to the heating circuit. When the temperature reaches the set value, the metal spring deforms due to heat, thus cutting off the circuit. However, this design lacks effective control over temperature differences in different areas of the pot in practical applications and cannot meet the needs of multi-level heating. The above technology demonstrates the limitations of existing technologies.

[0004] Therefore, we have made improvements to this and proposed a dual-temperature control device to prevent scorching. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing constant temperature control equipment is difficult to balance heating efficiency and temperature uniformity during the heating process of cookware, and is prone to sticking or burning due to local overheating.

[0006] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a dual-temperature control anti-scorching pot constant temperature control device, including a pot body assembly, a dual-temperature control module, and an adjustment component. The dual-temperature control module is located at the bottom of the pot body assembly and is used to independently control the temperature of different areas of the pot body. The adjustment component is connected above the dual-temperature control module and coordinates the working state of the dual-temperature control module through mechanical linkage. The outer side of the pot body assembly is provided with a heat insulation shell, and an air heat insulation layer is formed between the inner wall of the heat insulation shell and the pot body assembly. A heat-conducting sheet assembly is provided in the air heat insulation layer, and the heat-conducting sheet assembly is used to evenly distribute the heat of the pot body assembly to the entire surface of the pot body.

[0007] The dual temperature control module includes two independently configured temperature control units. Each temperature control unit includes a temperature sensing probe, a temperature control spring, and a heating plate. The temperature sensing probe is embedded in the bottom of the pot assembly and in direct contact with it. One end of the temperature control spring is connected to the temperature sensing probe, and the other end abuts against the circuit switch of the heating plate. When the temperature of a certain area of ​​the pot assembly rises, the temperature sensing probe expands due to heat, pushing the temperature control spring to deform, thereby triggering the circuit switch to cut off the heating circuit of that area. When the temperature drops, the temperature control spring returns to its original shape, and the circuit closes again.

[0008] As a preferred technical solution of this application, the adjustment component includes an adjustment rod and a linkage. The adjustment rod passes through the heat insulation shell and is fixedly connected to the linkage. The two ends of the linkage are respectively abutted against the temperature control springs of the two temperature control units. By manually rotating the adjustment rod, the linkage is moved, thereby changing the initial compression of the two temperature control springs, so that the trigger temperature range of the two temperature control units can be adjusted according to actual needs.

[0009] As a preferred technical solution of this application, the pot body assembly includes an inner pot body and an outer pot body. A heat-conducting medium layer is provided between the inner pot body and the outer pot body. The heat-conducting medium layer is filled with a low-melting-point metal alloy. The low-melting-point metal alloy melts and flows during the heating process of the pot body, transferring heat from the high-temperature area to the low-temperature area, thereby further improving the temperature uniformity of the pot body surface.

[0010] As a preferred technical solution of this application, the top of the heat insulation shell is provided with an annular boss, and the inner side of the annular boss is provided with a plurality of exhaust holes communicating with the air insulation layer. The exhaust holes are evenly distributed along the circumference of the annular boss to discharge excess heat in the air insulation layer and prevent the heat insulation shell from affecting the service life of the equipment due to excessive internal temperature.

[0011] As a preferred technical solution of this application, the heat-conducting sheet group includes a plurality of arc-shaped heat-conducting sheets. The two ends of the arc-shaped heat-conducting sheets are welded and fixed to the inner pot body and the outer pot body respectively. A gap is left between two adjacent arc-shaped heat-conducting sheets, and the gap is filled with thermally conductive silicone. The thermally conductive silicone is used to enhance the thermal conductivity between the arc-shaped heat-conducting sheets.

[0012] As a preferred technical solution of this application, the top of the adjusting rod is provided with a knob, the outer side of the knob is provided with anti-slip texture, and a sealing ring is provided between the bottom of the knob and the heat insulation shell. The sealing ring is used to prevent external dust or liquid from entering the air insulation layer.

[0013] As a preferred technical solution of this application, the linkage includes two symmetrically arranged push rods. One end of the push rod is threadedly connected to the adjusting rod, and the other end abuts against the end of the temperature control spring. By rotating the adjusting rod, the extension length of the push rod is changed, thereby adjusting the initial compression of the temperature control spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The dual-temperature control module enables independent temperature regulation of different areas of the pot body components, solving the problem of uneven temperature caused by a single sensor in traditional constant temperature control equipment. The synergistic effect of the low-melting-point metal alloy in the heat-conducting medium layer and the heat-conducting fins further improves the uniformity of temperature distribution on the pot surface, preventing sticking or burning caused by localized overheating. The adjustable component design allows users to flexibly adjust the trigger temperature range of the two temperature control units according to actual cooking needs, meeting the requirements of multiple heating levels. The structural design of the heat-insulating shell and air insulation layer effectively reduces the external temperature of the equipment, improving safety during use.

[0015] This invention solves the shortcomings of existing constant temperature control equipment in terms of heating efficiency, temperature uniformity, and safety through specific mechanical structure design and application of heat conduction principles. It also features easy operation and moderate manufacturing cost, making it suitable for home and commercial cooking scenarios. Attached Figure Description

[0022] This utility model provides a dual-temperature control anti-sticking constant temperature control device, the overall structure of which is as follows: Figure 1 As shown, the device mainly includes a pot body assembly 1, a heat insulation shell 2, and an adjustment assembly. The pot body assembly 1 is located at the core of the device, and the heat insulation shell 2 is disposed on its outer side, forming an air insulation layer between the two. The adjustment assembly penetrates the heat insulation shell 2 and is connected to the dual temperature control module of the pot body assembly 1. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0023] The pot assembly 1 consists of an inner pot and an outer pot, with a heat-conducting medium layer 9 between them. The heat-conducting medium layer 9 is filled with a low-melting-point metal alloy, which melts and flows during heating, thereby transferring heat from high-temperature areas to low-temperature areas. The inner pot and outer pot are fixed together by welding to ensure the airtightness of the heat-conducting medium layer 9. A heat-conducting fin assembly 8 is disposed within an air insulation layer, with its two ends welded to the inner and outer pots respectively. A gap is left between adjacent arc-shaped heat-conducting fins, filled with thermally conductive silicone to enhance heat conduction. The function of the heat-conducting fin assembly 8 is to evenly distribute the heat of the pot assembly 1 across the entire pot surface, thereby reducing temperature differences.

[0024] A dual-temperature control module is located at the bottom of the pot body assembly 1 to independently regulate the temperature of different areas of the pot body. The dual-temperature control module includes two independently configured temperature control units, each containing a temperature sensor 5, a temperature control spring 6, and a heating plate 7. The temperature sensor 5 is embedded in and in direct contact with the bottom of the pot body assembly 1 to sense temperature changes at the bottom of the pot body in real time. One end of the temperature control spring 6 is connected to the temperature sensor 5, and the other end abuts against the circuit switch of the heating plate 7. When the temperature of a certain area of ​​the pot body assembly 1 rises, the temperature sensor 5 expands due to heat, pushing the temperature control spring 6 to deform, thereby triggering the circuit switch to cut off the heating circuit of that area; when the temperature drops, the temperature control spring 6 returns to its original shape, and the circuit closes again, thus achieving temperature control of that area. The arrangement of the two temperature control units in the dual-temperature control module is as follows... Figure 3 As shown, the two work independently, each corresponding to a different heating zone of the pot body component 1, thus avoiding the problem of uneven temperature caused by detection by a single sensor.

[0025] The adjustment assembly includes an adjustment rod 3, a linkage 4, and a push rod 14. The adjustment rod 3 passes through the insulation shell 2 and is fixedly connected to the linkage 4. Both ends of the linkage 4 abut against the temperature control springs 6 of the two temperature control units, respectively. A knob 12 is located at the top of the adjustment rod 3, and the outer side of the knob 12 has anti-slip textures for easy operation. A sealing ring 13 is located between the bottom of the knob 12 and the insulation shell 2; the sealing ring 13 prevents external dust or liquid from entering the air insulation layer. The linkage 4 includes two symmetrically arranged push rods 14. One end of the push rod 14 is threadedly connected to the adjustment rod 3, and the other end abuts against the end of the temperature control spring 6. By rotating the adjustment rod 3, the extension length of the push rod 14 is changed, thereby adjusting the initial compression of the temperature control spring 6. The change in the initial compression affects the triggering condition of the temperature control spring 6, allowing the triggering temperature range of the two temperature control units to be adjusted according to actual needs. The structure and connection relationship of the adjustment assembly are as follows: Figure 4 As shown.

[0026] The top of the heat insulation shell 2 is provided with an annular boss 10, and several exhaust holes 11 are opened on the inner side of the annular boss 10. The exhaust holes 11 are evenly distributed along the circumference of the annular boss 10. The exhaust holes 11 are connected to the air insulation layer and are used to dissipate excess heat in the air insulation layer, preventing the heat insulation shell 2 from affecting the service life of the equipment due to excessive internal temperature. The distribution of the annular boss 10 and the exhaust holes 11 is as follows. Figure 5 As shown.

[0027] In actual use, the user first rotates the knob 12 on the adjustment lever 3 according to cooking needs, adjusting the initial compression of the temperature control springs 6 of the two temperature control units via the linkage 4, thereby setting different trigger temperature ranges. Subsequently, the heating plate 7 begins operation, and heat is transferred to the inner and outer pot bodies of the pot assembly 1 through the heat-conducting medium layer 9. The low-melting-point metal alloy within the heat-conducting medium layer 9 melts and flows during heating, transferring heat from high-temperature areas to low-temperature areas, further improving the temperature uniformity of the pot surface. Simultaneously, the heat-conducting sheet group 8 evenly distributes heat across the entire pot surface, reducing the possibility of localized overheating. The temperature sensor 5 monitors the temperature changes at the bottom of the pot in real time and controls the circuit switch of the heating plate 7 via the temperature control spring 6. When the temperature of a certain area exceeds the set value, the temperature sensor 5 pushes the temperature control spring 6 to deform, cutting off the heating circuit in that area; when the temperature decreases, the temperature control spring 6 returns to its original state, and the circuit recloses. This process ensures that all areas of the pot assembly 1 remain within a suitable temperature range.

[0028] During prolonged use, heat within the air insulation layer is dissipated through the exhaust vent 11, preventing damage to the insulation housing 2 due to excessive internal temperature. Furthermore, the sealing ring 13 effectively prevents external dust or liquids from entering the air insulation layer, ensuring long-term stable operation of the equipment.

[0029] This invention achieves independent temperature control of different areas of the pot body component 1 through the above-described specific embodiments, solving the problem of uneven temperature caused by a single sensor in traditional constant temperature control equipment. Simultaneously, the synergistic effect of the low-melting-point metal alloy in the heat-conducting medium layer 9 and the heat-conducting sheet group 8 further improves the uniformity of temperature distribution on the pot surface, preventing sticking or burning caused by localized overheating. The design of the adjustment component allows users to flexibly adjust the trigger temperature range of the two temperature control units according to actual cooking needs, meeting the requirements of multi-level heating. The structural design of the heat-insulating shell 2 and the air insulation layer effectively reduces the external temperature of the equipment, improving safety during use.

[0030] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0031] During cooking, the user first adjusts the temperature control parameters of the device according to actual needs. By rotating the knob 12 at the top of the adjusting rod 3, the linkage 4 is displaced, and the push rods 14 at both ends abut against the temperature control springs 6 in the two temperature control units respectively. Since the push rods 14 and the adjusting rod 3 are connected by threads, rotating the knob 12 changes the extension length of the push rods 14, thereby adjusting the initial compression of the temperature control springs 6. The initial compression of the temperature control springs 6 determines the temperature threshold at which the temperature sensor 5 triggers the circuit switch of the heating plate 7. Therefore, different trigger temperature ranges for the two temperature control units can be set through this operation. For example, in a frying scenario, the user may need one side of the pot to maintain a higher temperature to quickly heat the food, while the other side needs a lower temperature to avoid overheating and burning. At this time, differential control of the dual temperature zones can be achieved by adjusting the knob 12.

[0032] Subsequently, the heating plate 7 begins operation and transfers heat to the pot assembly 1. The heat is distributed through a low-melting-point metal alloy within the heat-conducting medium layer 9. This alloy gradually melts and flows during heating, rapidly transferring heat from high-temperature areas to low-temperature areas. This dynamic heat conduction mechanism effectively reduces temperature differences on the pot surface. Simultaneously, the heat-conducting plate assembly 8 further enhances the uniform distribution of heat. The heat-conducting plate assembly 8 consists of several arc-shaped heat-conducting plates, with their ends welded to the inner and outer pot bodies respectively. The gaps between adjacent heat-conducting plates are filled with thermally conductive silicone, ensuring efficient heat transfer to the entire pot surface. This design not only improves the overall heating efficiency of the pot but also significantly reduces the risk of localized overheating.

[0033] During heating, the temperature sensor 5 monitors the temperature changes at the bottom of the pot in real time. When the temperature in a certain area exceeds the preset value, the temperature sensor 5 expands due to heat, causing the temperature control spring 6 to deform, which in turn triggers the circuit switch to cut off the power supply to the heating plate 7 in that area. As the temperature drops, the temperature control spring 6 gradually returns to its original shape, the circuit closes again, and the heating plate 7 restarts. This closed-loop feedback mechanism ensures that the temperature in different areas of the pot remains within a suitable range, avoiding the uneven temperature problem caused by a single sensor in traditional constant temperature control equipment. For example, during stewing, the central area of ​​the pot may generate more heat due to the accumulation of food. At this time, the dual temperature control module can independently adjust the heating status of the central and edge areas, ensuring that the food is heated evenly and does not stick to the pot.

[0034] During prolonged use, heat within the air insulation layer is dissipated through the vents 11 on the annular boss 10. The vents 11 are evenly distributed circumferentially along the annular boss 10 and communicate with the air insulation layer, forming an effective heat dissipation channel. This design not only prevents damage to the insulation housing 2 due to excessive internal temperature but also further enhances the safety of the equipment. Furthermore, the sealing ring 13, installed between the bottom of the knob 12 and the insulation housing 2, provides a good seal, preventing external dust or liquid from entering the air insulation layer, thereby ensuring long-term stable operation of the equipment.

[0035] As can be seen from the above steps, this invention achieves uniform temperature distribution on the pot surface through the synergistic effect of the dual temperature control module, the heat-conducting medium layer 9, and the heat-conducting sheet group 8, thus solving the problem of sticking or burning caused by localized overheating. The design of the adjustment component allows users to flexibly adjust the temperature control parameters according to different cooking needs, meeting the requirements of multi-level heating. At the same time, the structural design of the heat-insulating shell 2 and the air insulation layer effectively reduces the external temperature of the device, further improving the safety of use. These designs together constitute a highly efficient, safe, and easy-to-operate constant temperature control device, suitable for both home and commercial cooking scenarios.

[0036] All content not described in detail in this specification is prior art known to those skilled in the art, and the model parameters of each component are not specifically limited; conventional equipment can be used. Electrical control components not mentioned in this technical solution are prior art and are therefore not shown in the figures, nor will they be described further here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
