Description

Technical Field

[0001] This disclosure relates to the field of cooking technology, and more specifically to a cooking device. Background Technology

[0002] With societal development, intelligent cooking equipment is becoming increasingly popular in the market. During the operation of intelligent cooking equipment, temperature control is the core factor determining cooking quality. More importantly, if the heating temperature gets out of control and exceeds the safety threshold, it may lead to risks such as the pot drying out, food catching fire, and the evaporation of the pot's coating forming toxic and harmful gases.

[0003] In existing technologies, infrared radiation can be used for temperature measurement. Specifically, the temperature measurement module includes a heat-conducting component that is in direct contact with the pot body. This component conducts the pot body temperature and emits infrared radiation towards an infrared thermometer. The pot body temperature can be calculated based on the infrared radiation received by the infrared thermometer. However, the receiving angle of an infrared thermometer is typically a fixed value. If the size of the heat-conducting component is too small, or the area directly opposite the infrared thermometer is too small, the infrared radiation emitted by the component will not fill the receiving field of view of the infrared thermometer, resulting in the reception of some environmental clutter radiation and causing a deviation in the measured temperature value. Summary of the Invention

[0004] This disclosure provides a cooking device to address the problems existing in the prior art.

[0005] According to a first aspect of this disclosure, a cooking apparatus is provided, comprising:

[0006] Pot body;

[0007] A heating base is used to support the pot body and heat the pot body;

[0008] A temperature measuring module is mounted on the heating base. The temperature measuring module includes a bracket, and a detection component and a heat-conducting component mounted on the bracket. The heat-conducting component is used to contact the pot body to conduct the temperature of the pot body. The heat-conducting component includes a cover portion facing the detection component, the cover portion being configured to emit infrared radiation toward the detection component. The detection component is configured to receive the infrared radiation emitted by the cover portion to detect the temperature of the heat-conducting component.

[0009] The heat-conducting component is installed on the bracket at one end adjacent to the pot body. The distance between the detection component and the heat-conducting component is denoted as L. The diameter D of the covering part is greater than or equal to 2L*tan(α / 2), where α is the receiving angle of the infrared radiation received by the detection component.

[0010] In one embodiment of this disclosure, L > 20 mm.

[0011] In one embodiment of this disclosure, the temperature at the location of the detection component is less than 75°C.

[0012] In one embodiment of this disclosure, the detection component includes an infrared thermometer, the infrared thermometer receiving infrared radiation at an angle α ≥ 35°.

[0013] In one embodiment of this disclosure, D > 12.61 mm.

[0014] In one embodiment of this disclosure, the heat-conducting component is configured as a sleeve structure and is configured to be sleeved on the support adjacent to one end of the pot body; the thickness of the end face of the sleeve structure in contact with the pot body is 0.4-0.6 mm.

[0015] In one embodiment of this disclosure, the temperature measuring module is configured to be movably mounted on the heating base via an elastic element; when the pot body is placed on the heating base, the temperature measuring module moves to a first position under the pressure of the pot body; when in the first position, the heat-conducting component is configured to contact and engage with the pot body; when the pot body is detached from the heating base, the temperature measuring module moves upward to a second position under the action of the elastic element.

[0016] In one embodiment of this disclosure, the heating seat includes a bearing surface for supporting the pot body, and the heating seat has a movable cavity, in which the temperature measuring module is movably installed; when in the second position and the first position, at least a portion of the heat-conducting component is configured to protrude from the bearing surface.

[0017] In one embodiment of this disclosure, a protrusion is provided on the bearing surface. When the pot body is placed on the heating base, the pot body is supported on the protrusion and the temperature measuring module. When in the second position, the height of the heat-conducting component protruding from the bearing surface is greater than or equal to the height of the protrusion protruding from the bearing surface.

[0018] In one embodiment of this disclosure, the protrusion includes an auxiliary temperature measuring element. When the temperature of the pot body is higher than a first temperature threshold, the cooking device stops working based on a trigger signal from the auxiliary temperature measuring element.

[0019] In one embodiment of this disclosure, the protrusion includes a safety element, which is provided with a fuse; when the temperature of the pot body is higher than a second temperature threshold, the fuse melts, thereby stopping the trigger signal of the auxiliary temperature measuring element from working; wherein, the second temperature threshold is higher than the first temperature threshold.

[0020] In one embodiment of this disclosure, three protrusions are provided, two of which are auxiliary temperature measuring components and the other is a safety component.

[0021] In one embodiment of this disclosure, the three protrusions are arranged in an equilateral triangle on the bearing surface.

[0022] In one embodiment of this disclosure, the movable cavity is located at the center of the heating seat.

[0023] One beneficial effect of this disclosure is that by limiting the diameter of the coverage portion D to ≥ 2L*tan(α / 2), it can be ensured that the coverage portion completely fills the receiving field of view of the detection component, preventing environmental clutter radiation from entering. For the detection component, the entire area within its receiving angle is directly facing the coverage portion and will not hit the sidewall of the radiation cavity, thereby ensuring that the detection component can collect a sufficient amount of data, thus improving the accuracy of the detection. This disclosure provides a clear dimensional formula to provide a quantitative basis for the design of the heat-conducting component, avoiding problems such as incomplete infrared field of view or obstruction caused by incorrect design of the heat-conducting component size.

[0024] Other features and advantages of this disclosure will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0045] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0046] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0047] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0048] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0049] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0050] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0051] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0052] refer to Figure 1 and Figure 2 This disclosure provides a cooking device comprising: a pot body 1, a heating base 2, a cantilever arm 6, and a stirring spatula 7, all components working together to automate the cooking process. The pot body 1 is used to hold food and has good thermal conductivity, thereby heating the food inside to complete the cooking process (e.g., frying, stir-frying, boiling, deep-frying, etc.). For example, the pot body 1 can be a flat-bottomed pan or a round-bottomed pan, and the material can be stainless steel, iron, aluminum, earthenware, copper, enamel, non-stick, or composite material.

[0053] refer to Figure 3 The heating base 2 is disposed in the base area of ​​the cooking device, serving to support the pot body 1 and heat it. In one embodiment of this disclosure, the heating base 2 is provided with a coil assembly 29, which is configured to heat the pot body 1. Specifically, the coil assembly 29 is the core heating element of the cooking device, configured to heat the pot body 1 through electromagnetic induction. Its output power can be flexibly adjusted according to a preset cooking program to ensure stable heat transfer to the pot body 1. Simultaneously, the coil assembly 29 can be evenly distributed within the heating base 2, thereby covering the entire bottom surface of the pot body 1, ensuring uniform heat transfer and even heating of the food inside the pot body 1.

[0054] refer to Figure 2 The cantilever 6 is an auxiliary operating component of the cooking equipment. One end is rotatably or fixedly connected to the main body of the equipment, and the other end extends above the pot body 1. A lid for closing the pot body 1 is installed on the cantilever 6, allowing the pot body 1 to be closed during cooking to achieve functions such as braising and heat preservation. In addition, a pipe connected to an external seasoning box can be installed inside the cantilever 6, which can automatically add seasonings to the pot body 1 according to the cooking program, reducing manual operation.

[0055] refer to Figure 2 The stirring spatula 7 is mounted inside the pot body 1 or on the extension end of the cantilever 6. It is driven by a drive mechanism (such as a motor) to achieve rotation or reciprocating motion, thereby stirring the ingredients in the pot body 1 during cooking, preventing the ingredients from overheating and burning in some areas, and ensuring that the ingredients and seasonings are evenly mixed to improve the cooking effect.

[0056] In the operation of intelligent cooking equipment, temperature control is the core factor determining cooking quality. Specifically, different ingredients (such as meat, vegetables, and grains) have different optimal cooking temperature ranges. If the temperature is too high, the food will easily burn and lose nutrients, while if the temperature is too low, the food will be undercooked and lack flavor. In addition, temperature stability directly affects cooking safety. If the heating temperature gets out of control and exceeds the safety threshold, it may cause risks such as dry burning of the pot, food catching fire, and evaporation of the pot coating to form toxic and harmful gases. Therefore, a reliable temperature measurement and control scheme is needed to ensure precise and controllable temperature.

[0057] Currently, most mainstream cooking equipment on the market uses NTC thermistors as temperature sensing and control elements. While this solution offers advantages such as simple structure and low cost, the temperature measurement accuracy of NTC thermistors is easily affected by factors such as ambient temperature, component aging, installation location, and oil contamination. Figure 16 In practical applications, the temperature control error of NTC thermistors can reach ±40℃, which cannot meet the temperature accuracy requirements of intelligent cooking.

[0058] To address the aforementioned issues, this disclosure employs an infrared temperature control scheme to replace the traditional NTC temperature control scheme. The infrared temperature control is based on conventional physical principles and mature technologies: According to the basic principles of thermal radiation physics, any object above absolute zero emits electromagnetic waves, of which electromagnetic waves with wavelengths in the range of 0.75-1000 μm are called infrared radiation; the radiated energy of an object is positively correlated with its surface temperature, and the wavelength distribution of radiated energy differs at different temperatures (e.g., high-temperature objects emit stronger short-wave radiation).

[0059] Based on the above principles, the current temperature of the pot body 1 can be calculated by detecting the infrared radiation emitted by the pot body 1, thereby achieving precise temperature control. Preferably, the infrared thermometer 311 is a mature temperature detection element that can receive infrared radiation and calculate the temperature of the radiating object based on the correspondence between radiation energy and temperature, thus obtaining the actual temperature of the pot body 1. This solution can effectively avoid the error defects of NTC thermistors and provide reliable temperature data support for precise temperature control.

[0060] In one existing practical solution, an infrared thermometer 311 can be installed inside the heating base 2, and a lens can be installed on the heating base 2. The lens can filter out ambient noise radiation, allowing only infrared radiation from the pot 1 to pass through, while also blocking oil stains generated during cooking to avoid contaminating the infrared thermometer 311. The infrared radiation filtered by the lens is received by the infrared thermometer 311, which calculates the temperature of the pot 1 based on the received radiation energy. Although this solution offers some improvement in temperature measurement accuracy compared to NTC thermistors, the oil fumes generated during cooking easily adhere to the lens surface, forming oil stains, which reduces the lens's transmittance of infrared radiation and significantly lowers the temperature measurement accuracy. In addition, the lens has a high production cost, which is detrimental to cost control of cooking equipment.

[0061] Based on the problems existing in the prior art, and referring to Figures 7 to 9 The cooking device disclosed herein includes a temperature measuring module 3, which includes a detection component 31 and a heat-conducting component 32 fixed relative to the detection component 31. The heat-conducting component 32 is used to contact the pot body 1 to conduct the temperature of the pot body 1 and emit infrared radiation to the detection component 31. The detection component 31 is configured to receive the infrared radiation emitted by the heat-conducting component 32 to detect the temperature of the heat-conducting component 32. The heat-conducting component 32 may be made of a metal material with high thermal conductivity. Its side away from the detection component 31 is used to make close contact with the pot body 1, so that the heat of the pot body 1 can be conducted to the heat-conducting component 32, making the temperature of the heat-conducting component 32 the same as that of the pot body 1, and emitting infrared radiation to the detection component 31. The detection component 31 may include an infrared thermometer 311, which can receive the infrared radiation emitted by the heat-conducting component 32 in real time, thereby indirectly obtaining the temperature of the pot body 1.

[0062] Compared to traditional NTC thermistor temperature control solutions, the temperature measurement module 3 disclosed herein significantly improves temperature control accuracy. (Refer to...) Figure 17 Under extreme experimental conditions (dry heating of pot 1 + oil stains), the temperature control error using the temperature measuring module 3 provided in this disclosure is less than ±10℃, thus meeting the high-precision temperature control requirements of cooking. Furthermore, compared to the infrared temperature measurement + lens solution, the temperature measuring module 3 avoids the problems of lens contamination leading to decreased accuracy and high lens cost, reducing the production cost of cooking equipment and the maintenance burden on users.

[0063] refer to Figure 4 and Figure 6 The temperature measuring module 3 is configured to be movably mounted on the heating base 2 via an elastic element 4. When the pot body 1 is placed on the heating base 2, the temperature measuring module 3 moves to the first position under the pressure of the pot body 1. (Reference) Figure 3 and Figure 4 When in the first position, the heat-conducting component 32 is configured to contact and engage with the pot body 1. (Reference) Figure 5 and Figure 6 When the pot body 1 detaches from the heating base 2, the temperature measuring module 3 moves to the second position under the action of the elastic element 4. Specifically, as shown... Figure 3 As shown, the pot body 1's own weight or external pressure can overcome the elastic force of the elastic element 4, thereby pushing the temperature measuring module 3 to the first position. At this time, as... Figure 4 As shown, the heat-conducting component 32 can be completely fitted to the pot body 1 to form a stable heat conduction path. When the user removes the pot body 1 from the heating base 2, as... Figure 5 As shown, the pre-pressure release of the elastic element 4 pushes the temperature measuring module 3 back to the second position. The movable structure driven by the elastic element 4 ensures that the heat-conducting component 32 is always in contact when the pot body 1 is placed and automatically resets when it is detached, thereby avoiding poor contact caused by the placement deviation of the pot body 1 and improving the reliability of temperature measurement.

[0064] In this disclosure, the detection component 31 and the heat-conducting component 32 are relatively fixed, thereby avoiding distance shifts, coaxiality deviations, or angular misalignments between the two during the movement of the temperature measuring module 3. This prevents fluctuations in the receiving angle and emissivity of the detection component 31, thus improving the accuracy and stability of temperature measurement. Specifically, during infrared temperature measurement, the emissivity of the heat-conducting component 32 needs to remain constant based on the stable relative posture of the emitting surface and the receiving end 3110. If the relative positions of the two change, the intensity and angle of the radiation energy received by the detection component 31 will fluctuate, leading to misjudgment of the emissivity and resulting in temperature measurement errors. This disclosure, through rigid relative fixation, ensures that the infrared emitting surface of the heat-conducting component 32 is always aligned with the detection component 31 at a stable distance and coaxial posture, maintaining a constant emissivity parameter. This avoids emissivity fluctuation errors caused by movement between the first and second positions, ensuring the accuracy and stability of temperature measurement.

[0065] As mentioned earlier, the heating base 2 is equipped with a coil assembly 29 for heating the pot body 1. Those skilled in the art will know that electromagnetic heating is the mainstream method in intelligent cooking equipment due to its high heating efficiency. Its principle is that the coil assembly 29 in the heating base 2 generates an alternating magnetic field through a high-frequency current, causing the pot body 1 to generate heat. However, the strong magnetic field generated by the coil assembly 29 severely interferes with the infrared thermometer 311, leading to a decrease in temperature measurement accuracy and affecting the temperature control function. While placing the infrared thermometer 311 away from the coil assembly 29 can reduce the magnetic field strength, the temperature at the edge of the pot body 1 is lower than at the center, so the measured temperature cannot reflect the true temperature of the pot body 1, still resulting in temperature control deviation.

[0066] To solve the above problems, in one embodiment of this disclosure, reference is made to... Figure 7 and Figure 9The detection component 31 also includes a shielding member 313 fitted around the outer periphery of the infrared thermometer 311. The shielding member 313 can be fixedly installed around the outer periphery of the infrared thermometer 311 and can move together with the temperature measuring module 3 between a first position and a second position. The shielding member 313 is configured to shield the magnetic field of the coil assembly 29. Preferably, the shielding member 313 is a magnetic ring fitted around or enclosing the infrared thermometer 311. The shielding member 313 can shield the influence of the magnetic field of the coil assembly 29 on the infrared thermometer 311, significantly attenuating the interference of the magnetic field of the coil assembly 29 on the infrared thermometer 311, thereby ensuring the accuracy of the infrared thermometer 311 and thus ensuring temperature control precision. Furthermore, the shielding member 313, fitted around the outer periphery of the infrared thermometer 311, is small in size and achieves the shielding effect without occupying too much space. The annular structure of the shielding member 313 surrounds the infrared thermometer 311 in all directions, resulting in a higher magnetic field attenuation rate and more comprehensive anti-interference effect compared to a semi-enclosed shielding member 313. This invention uses physical shielding to eliminate interference, thus eliminating the need for complex software algorithms, reducing the computing power burden on the main control system, and also enabling it to cope with sudden strong magnetic fields, resulting in stronger anti-interference stability.

[0067] In one embodiment of this disclosure, reference is made to Figure 3 and Figure 4 The detection component 31 is configured to be located inside the heating base 2, with the coil assembly 29 surrounding it. Specifically, the detection component 31 is located at the center of the coil assembly 29, corresponding to the central area of ​​the pot body 1, where the temperature is relatively uniform, and the measured temperature value is more representative than that at the edge, thereby reducing temperature control deviation. The coil assembly 29 surrounds the detection component 31, and a shield 313 surrounds the outer periphery of the detection component 31, thereby completely blocking the magnetic field of the coil assembly 29 and protecting the infrared thermometer 311 from magnetic field interference.

[0068] In one embodiment of this disclosure, reference is made to Figure 7 The temperature measuring module 3 also includes a bracket 33, which is preferably made of high-temperature resistant engineering plastic and serves as the mounting base for the heat-conducting component 32 and the detection component 31. The heat-conducting component 32 is fixedly mounted on the bracket 33 at one end adjacent to the pot body 1, while the detection component 31 is mounted on the bracket 33 at the end away from the pot body 1, with a predetermined distance between them. The bracket 33 provides a stable mounting surface for the heat-conducting component 32 and the detection component 31, ensuring their relative positions are fixed and preventing positional shifts caused by equipment vibration or cooking shaking, thus improving temperature measurement stability.

[0069] Specifically, such as Figure 4As shown, the end face of the heat-conducting component 32 extends beyond the end face of the bracket 33, thereby ensuring that the heat-conducting component 32 makes preferential contact with the pot body 1. The detection component 31 is installed at a position away from the pot body 1, thus avoiding damage to the detection component 31 due to the high temperature of the pot body 1 and the heat-conducting component 32, and avoiding interference from the high temperature of the environment on the accuracy of infrared detection. At the same time, the infrared thermometer 311 needs to maintain a preset distance from the heat-conducting component 32 to maintain a preset infrared radiation emission angle, ensuring the infrared radiation reception efficiency and improving the accuracy of temperature measurement.

[0070] In one embodiment of this disclosure, reference is made to Figure 9 and Figure 4 The bracket 33 is configured to at least enclose a radiation cavity 331 with an open end, and the heat-conducting component 32 is configured to cover the open end of the radiation cavity 331. The receiving end 3110 of the detection component 31 is configured to face the heat-conducting component 32, so that the heat radiation from the heat-conducting component 32 is transferred to the receiving end 3110 of the detection component 31 through the radiation cavity 331. By setting the radiation cavity 331 in the bracket 33, an independent infrared radiation transmission channel is formed, which can isolate the heat of the coil assembly 29 inside the heating seat 2, stray light from the external environment, and other interference factors, avoiding the influence of stray radiation on the detection results of the infrared thermometer 311 and improving the temperature measurement accuracy. At the same time, the radiation cavity 331 can reduce the outward loss of infrared radiation emitted by the heat-conducting component 32, ensuring that the detection component 31 can efficiently receive radiation energy, thereby avoiding detection errors caused by weak radiation energy.

[0071] In one embodiment of this disclosure, reference is made to Figure 7 The heat-conducting component 32 includes a cover portion 321 covering the open end and a sidewall portion 322 located at the edge of the cover portion 321. The sidewall portion 322 is configured to fit over the outside of the support 33. The cover portion 321 can be a circular flat plate structure, which is used for contact with the bottom surface of the pot body 1 and for covering the open end of the radiation cavity 331, thereby blocking oil and preventing oil from entering the radiation cavity 331 and contaminating the detection component 31. The sidewall portion 322 is an annular structure that extends vertically downward from the edge of the cover portion 321. The inner wall of the cover portion 321 fits with the outer wall of the open end of the support 33, thereby tightly fitting over the outside of the support 33.

[0072] Specifically, the heat-conducting component 32 is constructed as a sleeve structure and is fitted onto the support 33 at one end adjacent to the pot body 1. The cover portion 321 is the top surface of the sleeve structure, and the side wall portion 322 is the flange of the sleeve structure. The cover portion 321 and the side wall portion 322 can be integrally formed, thereby simplifying the processing technology of the heat-conducting component 32 and improving the overall structural strength of the heat-conducting component 32, avoiding deformation caused by long-term high-temperature use. This disclosure uses a sleeve structure to enhance the connection stability between the heat-conducting component 32 and the support 33, preventing the heat-conducting component 32 from falling off or shifting due to shaking of the pot body 1 during cooking, thus improving the structural reliability of the equipment.

[0073] In one embodiment of this disclosure, reference is made to Figure 6 One end of the bracket 33 away from the heat-conducting component 32 is configured to form a mounting base 332 communicating with the radiation cavity 331. The detection component 31 is configured to be located within the mounting base 332, and the end face of the detection component 31 is configured to abut against the bottom of the radiation cavity 331. In this embodiment, the end face of the shielding component 313 is configured to abut against the bottom of the radiation cavity 331. Specifically, the mounting base 332 is used to provide installation space for the detection component 31, and its inner diameter is adapted to the size of the detection component 31, which can limit and fix the detection component 31. The internal channel of the mounting base 332 communicates with the radiation cavity 331, thereby forming a continuous radiation transmission path. The mounting base 332 provides a precise positioning reference for the detection component 31. The structure in which the end face of the detection component 31 abuts against the radiation cavity 331 can avoid axial displacement of the detection component 31 due to vibration and assembly errors, ensuring that the receiving end 3110 of the detection component 31 remains directly facing the center of the radiation cavity 331, maximizing the radiation receiving efficiency.

[0074] In one embodiment of this disclosure, reference is made to Figure 9 and Figure 10 The mounting base 332 has a first heat dissipation vent 333 on its side wall, exposing the side wall of the detection component 31. Specifically, the shielding component 313 can be exposed through this first heat dissipation vent 333. The first heat dissipation vent 333 can quickly dissipate the heat generated by the detection component 31 during operation, thereby reducing the temperature of the detection component 31 itself and its ambient temperature, preventing the detection component 31 from experiencing a decrease in accuracy or component aging due to high temperature, and extending the service life of the detection component 31. Multiple first heat dissipation vents 333 can be arranged around the side wall of the mounting base 332. Optionally, multiple first heat dissipation vents 333 can be evenly distributed, thereby forming an air connection, improving heat dissipation efficiency, and preventing deformation of the mounting base 332 due to local overheating.

[0075] In one specific embodiment of this disclosure, reference is made to Figure 7 and Figure 9The support 33 includes an upper support 3301 with a radiation cavity 331, and a lower support 3302 that forms a mounting base 332 with the upper support 3301. At least two axially extending limiting posts 337 are provided on the upper support 3301 and / or the lower support 3302. These at least two limiting posts 337 are configured to restrict the sidewalls of the detection component 31; the interval between adjacent limiting posts 337 is configured to form a first heat dissipation vent 333. Specifically, this disclosure may provide four limiting posts 337 on the upper support 3301, and the limiting posts 337 and the upper support 3301 may be integrally formed. The four limiting posts 337 are evenly spaced circumferentially, i.e., the circumferential interval between adjacent limiting posts 337 is 90°, thereby forming a multi-point uniform constraint on the detection component 31. The detection component 31 is embedded in the space formed by the four limiting posts 337. Under the combined limiting action of the four limiting posts 337, the detection component 31 cannot be displaced in the radial direction, thereby ensuring the fixed installation of the detection component 31.

[0076] In this embodiment, there is no need to open an additional independent heat dissipation hole on the side wall of the bracket 33. The first heat dissipation port 333 is directly formed by the interval between adjacent limiting posts 337. This simplifies the processing technology of the bracket 33 and enables circumferential air convection through four evenly distributed heat dissipation ports, which quickly removes the heat generated by the detection component 31 during operation, reduces the temperature of the detection component 31 itself and the ambient temperature, avoids component aging or accuracy reduction caused by high temperature, and extends the service life of the detection component 31.

[0077] Furthermore, at least one limiting post 337 is provided with a screw hole 338 and is configured to fix the upper bracket 3301 and the lower bracket 3302 by screws. Specifically, in this embodiment, among the four limiting posts 337, two limiting posts 337 distributed opposite to each other along the central axis of the upper bracket 3301 are provided with axially extending screw holes 338, while the other two limiting posts 337 are only used as limiting structures and are not provided with screw holes 338. During assembly, high-temperature resistant screws adapted to the screw holes 338 are used and passed sequentially through the preset through hole 211 of the lower bracket 3302 and the screw holes 338 of the limiting posts 337, thereby fastening the upper bracket 3301 and the lower bracket 3302 together. After assembly, the two limiting posts 337 with screw holes 338 still maintain the fitting clearance with the side wall of the detection component 31 and continue to play a radial limiting role.

[0078] This disclosure achieves a centrally symmetrical screw fastening point distribution by creating screw holes 338 in two relatively distributed limiting posts 337. During tightening, the upper bracket 3301 and lower bracket 3302 experience uniform force, preventing deformation of the bracket 33 due to unilateral force and ensuring the coaxiality of the radiation cavity 331 and the mounting base 332. Furthermore, the limiting posts 337 with screw holes 338 simultaneously serve the dual functions of the radial limiting detection component 31 and fixing the upper and lower brackets 3302. This eliminates the need for additional independent fixing posts or connecting structures, reducing the structural complexity of the bracket 33, lowering production and assembly costs, and avoiding structural redundancy.

[0079] In one embodiment of this disclosure, reference is made to Figure 11 A second heat dissipation vent 334, penetrating the radiation cavity 331, is provided on the side wall of the bracket 33. Specifically, if the radiation cavity 331 is completely sealed, heat transferred by the heat-conducting component 32 will accumulate inside, creating a high-temperature environment, while the outside temperature of the radiation cavity 331 is relatively low. This temperature difference will cause water vapor in the air to condense on the inner wall of the radiation cavity 331 or on the surface of the infrared lens of the detection component 31. The condensate will block the infrared radiation transmission path and may even contaminate the lens, affecting the detection accuracy. This disclosure provides a second heat dissipation vent 334, which dissipates the heat accumulated inside the radiation cavity 331, reduces the temperature difference between the inside and outside of the radiation cavity 331, thereby preventing condensate formation, ensuring the cleanliness of the infrared lens, and preventing temperature measurement from being interfered with by water vapor.

[0080] Furthermore, similar to the aforementioned first heat dissipation vent 333, the second heat dissipation vent 334 can also be formed by enclosing a column. For example... Figure 11 As shown, the column structure is used to enclose and form a radiation cavity 331, and its end face can abut against the end face of the detection component 31, thereby forming an axial limit. The column can be set inside the limiting column 337, thereby enclosing a second heat dissipation port 334 corresponding to the first heat dissipation port 333 between two adjacent columns. The heat in the radiation cavity 331 can be discharged through the second heat dissipation port 334 and the first heat dissipation port 333, thereby reducing the temperature inside the radiation cavity 331. Preferably, the second heat dissipation port 334 is opened on the bracket 33 at a position relatively far away from the heat conduction component 32, thereby minimizing the impact of heat dissipation from the radiation cavity 331 on the infrared radiation at the heat conduction component 32 and avoiding a decrease in measurement accuracy due to excessive heat dissipation.

[0081] In one embodiment of this disclosure, reference is made to Figure 7The detection component 31 also includes a circuit board 312 connected to the infrared thermometer 311. The circuit board 312 is fixedly mounted on the bracket 33 and configured to be located on the side of the infrared thermometer 311 that is relatively far away from the heat-conducting component 32. Specifically, the circuit board 312 can be fixedly mounted on the lower bracket 3302, and a certain heat dissipation gap can be reserved between it and the infrared thermometer 311. This disclosure places the circuit board 312 in a position far away from the heat source (heat-conducting component 32), thereby avoiding the high temperature transmitted by the heat-conducting component 32 from affecting the working stability of electronic components (such as chips) on the circuit board 312 and reducing circuit failures. The circuit board 312 integrates a signal processing chip, which can convert the analog signal output by the infrared thermometer 311 into a digital signal and transmit it to the main control system of the cooking equipment to realize temperature feedback and temperature control adjustment.

[0082] In one embodiment of this disclosure, reference is made to Figure 3 and Figure 12 The heating base 2 includes a bearing surface 21 for supporting the pot body 1. A movable cavity 22 is formed on the heating base 2, and the temperature measuring module 3 is movably installed in the movable cavity 22. The movable cavity 22 can be configured to fit the overall size of the temperature measuring module 3. There is a movable gap between the temperature measuring module 3 and the inner wall of the movable cavity 22, and the depth of the movable cavity 22 is greater than the travel distance of the temperature measuring module 3. Therefore, it can move between a first position and a second position under the action of external force on the pot body 1. The movable cavity 22 provides a movement guide for the temperature measuring module 3, preventing the temperature measuring module 3 from shifting or tilting during movement, and ensuring that the heat-conducting component 32 can accurately contact the bottom surface of the pot body 1. (Reference) Figure 5 When in the second position, at least part of the heat-conducting component 32 is exposed outside the active cavity 22 and is configured to protrude from the bearing surface 21. The fact that the heat-conducting component 32 protrudes from the bearing surface 21 in the second position ensures that the pot body 1 is in priority contact with the heat-conducting component 32 when placed, avoiding poor contact caused by unevenness of the bearing surface 21 or deformation of the pot body 1, and improving the reliability of temperature measurement.

[0083] In one embodiment of this disclosure, the coil assembly 29 is arranged around the outer periphery of the movable cavity 22. Preferably, the axis of the coil assembly 29 coincides with the axis of the movable cavity 22, thereby ensuring that the magnetic field of the coil assembly 29 is evenly distributed. This facilitates the shielding member 313, which is sleeved on the outer periphery of the infrared thermometer 311, to stably and omnidirectionally attenuate the magnetic field and avoid shielding failure caused by excessive local magnetic field strength.

[0084] In one embodiment of this disclosure, reference is made to Figure 5 , Figure 12 and Figure 13A protrusion 23 is provided on the bearing surface 21. When the pot body 1 is placed on the heating base 2, the pot body 1 is supported by the protrusion 23 and the temperature measuring module 3. In the second position, the height of the heat-conducting component 32 protruding from the bearing surface 21 is greater than or equal to the height of the protrusion 23 protruding from the bearing surface 21. This ensures that when the pot body 1 is placed, the heat-conducting component 32 can fit tightly and fully against the bottom surface of the pot body 1, thereby ensuring heat conduction efficiency. At the same time, by providing the protrusion 23 on the bearing surface 21, which together with the temperature measuring module 3 supports the pot body 1, the protrusion 23 can share the weight of the pot body 1, thereby preventing the heat-conducting component 32 from deforming due to long-term excessive pressure, which would affect the heat conduction effect.

[0085] Specifically, refer to Figure 15 The protrusions 23 can be provided in three parts, preferably arranged in an equilateral triangle on the bearing surface 21. When the pot body 1 is placed on the heating base 2, the bottom surface of the pot body 1 is supported by the three protrusions 23 and the heat-conducting component 32, forming a four-point support structure. This can stably support the pot body 1, preventing it from tilting or shaking during cooking and improving cooking safety. Furthermore, an equilateral triangle is the most stable three-point support structure in a plane, which can evenly distribute the weight of the pot body 1, ensuring that the bottom surface of the pot body 1 is always in contact with the heat-conducting component 32, and ensuring the measurement accuracy of the temperature measuring module 3.

[0086] In one specific embodiment of this disclosure, the protrusion 23 includes an auxiliary temperature measuring element. When the temperature of the pot body 1 exceeds a first temperature threshold, the cooking device stops operating based on a trigger signal from the auxiliary temperature measuring element. Specifically, the auxiliary temperature measuring element can be an NTC thermistor or a temperature switch, which can be electrically connected to the main control system of the cooking device. This disclosure uses a temperature measuring module 3 for real-time temperature control based on infrared distance measurement. In the event of a failure of the temperature measuring module 3, the auxiliary temperature measuring element provides fallback protection. When the auxiliary temperature measuring element detects that the temperature of the pot body 1 exceeds the first temperature threshold, it immediately sends a trigger signal to the main control system. Upon receiving the signal, the main control system cuts off the power supply to the coil assembly 29 of the heating base 2, stopping heating and preventing the temperature from continuing to rise.

[0087] This disclosure employs a temperature measurement module 3 for precise temperature control, with an auxiliary temperature measurement component as a backup. This auxiliary component can trigger protection in case of a failure in the main temperature measurement module 3 (such as damage to the infrared thermometer 311 or poor contact in the heat-conducting component 32), preventing temperature runaway caused by a single temperature measurement failure and improving equipment safety redundancy. The auxiliary temperature measurement component, located on the bearing surface 21, directly contacts the pot body 1 for temperature transfer, enabling more accurate temperature measurement and rapid shutdown when the pot body 1 temperature exceeds a first temperature threshold, thus improving the safety of the cooking equipment.

[0088] In one specific embodiment of this disclosure, the protrusion 23 includes a safety element containing a fuse. When the temperature of the pot body 1 exceeds a second temperature threshold, the fuse melts, causing the trigger signal of the auxiliary temperature measuring element to stop working. The second temperature threshold is higher than the first temperature threshold. If both the temperature measuring module 3 and the auxiliary temperature measuring element fail to control the temperature, the temperature of the pot body 1 may continue to rise, posing a significant safety hazard. When the temperature of the pot body 1 continues to rise above the second temperature threshold, the fuse melts due to heat, thereby forcibly stopping heating and preventing serious risks such as fires caused by continuous heating.

[0089] This disclosure constructs a three-tiered safety barrier. In the event of a malfunction in both the temperature sensing module 3 and the auxiliary temperature sensing component, preventing accurate temperature control, the fuse can physically melt and forcibly stop heating. The second temperature threshold is higher than the first temperature threshold, ensuring that the fuse will not be falsely triggered during normal daily cooking, activating only in extremely dangerous scenarios, thus balancing cooking flexibility with safety protection. The fuse uses commonly used components in existing technologies, offering low procurement costs and easy assembly. Furthermore, it provides protection through physical melting, eliminating reliance on software logic from electronic components. This avoids protection failures caused by software or circuit malfunctions, improving the reliability and safety of the cooking equipment.

[0090] In one specific embodiment of this disclosure, reference is made to Figure 15 Three protrusions 23 are provided, two of which are auxiliary temperature measuring components, and the third is a safety component. All three protrusions 23 are distributed on the bearing surface 21 of the heating base 2 (e.g., arranged in an equilateral triangle), and are all located on the outside of the temperature measuring module 3. This ensures that when the pot body 1 is placed on the heating base 2, the bottom surface of the pot body 1 simultaneously contacts the three protrusions 23 and the heat-conducting component 32 of the temperature measuring module 3, forming a four-point bearing. Furthermore, the metal pillars of the three protrusions 23 have the same diameter and height, thereby preventing the pot body 1 from tilting due to differences in the height of the protrusions 23, ensuring a tight fit between the bottom surface of the pot body 1 and the heat-conducting component 32 of the temperature measuring module 3, indirectly guaranteeing the accuracy of the main temperature measurement.

[0091] Two auxiliary temperature sensors simultaneously detect the temperature at different locations on the pot body 1. The main control system can compare the detection data from both sensors to avoid misjudgments caused by poor contact or component aging of a single auxiliary temperature sensor, thus improving the reliability of auxiliary temperature measurement. In addition, the two auxiliary temperature sensors meet the requirements for backup and data verification, while a backup sensor provides ultimate safety protection. This ensures safety redundancy while reducing the number of components, lowering equipment production costs and assembly complexity.

[0092] In one embodiment of this disclosure, reference is made to Figure 15The temperature measuring module 3 is configured to be located at the center of the heating base 2. Correspondingly, the movable cavity 22 is opened at the center of the heating base 2. This position can coincide with the center of the coil assembly 29 inside the heating base 2 and correspond to the center bottom surface of the pot body 1. The central axis of the movable cavity 22 can coincide with the central axis of the heating base 2, ensuring that the heat-conducting component 32 of the temperature measuring module 3 can be accurately aligned with the center of the bottom surface of the pot body 1. It can be understood that the temperature in the central area of ​​the bottom surface of the pot body 1 is relatively uniform, while the temperature in the edge area is easily affected by heat dissipation and is lower. Therefore, the heat-conducting component 32 contacting the central area can obtain a more representative temperature of the pot body 1, thereby improving the accuracy of temperature measurement. In addition, the central position design is adapted to the usage habits of most round pot bodies 1. Users do not need to deliberately align the heat-conducting component 32 with the center of the pot body 1, which can achieve the fit between the heat-conducting component 32 and the center of the pot body 1, improving the convenience of use.

[0093] In one embodiment of this disclosure, the temperature measuring module 3 is configured to move vertically relative to the heating base 2, and the movable cavity 22 is vertically formed on the heating base 2. In its natural state, i.e., without the pot body 1 supporting it, the temperature measuring module 3 remains in the second position; when the pot body 1 is placed on the heating base 2, the temperature measuring module 3 moves downward to the first position under the influence of the pot body 1's gravity. Specifically, the vertical movement of the temperature measuring module 3 conforms to the direction of gravity, and the pot body 1's own gravity can drive the temperature measuring module 3 to move without the need for additional drive or transmission mechanisms, thereby simplifying the structure and reducing costs.

[0094] In one embodiment of this disclosure, such as Figure 7 As shown, the heat-conducting component 32 is fixedly installed on the top of the bracket 33, and the top end face of the heat-conducting component 32 is configured to fit the bottom surface of the pot body 1. The heat-conducting component 32 is sleeved and fixed at the top of the upper bracket 3301, and is used to fully contact the bottom surface of the pot body 1 to conduct heat. In the case where the bottom surface of the pot body 1 is flat, the top surface of the heat-conducting component 32 is correspondingly set as a flat surface; when the bottom surface of the pot body 1 is curved, the top surface of the heat-conducting component 32 is correspondingly set as a curved surface with the same curvature. Adapting the end face shape to the bottom surface of the pot body 1 can maximize the contact area between the heat-conducting component 32 and the pot body 1, improve the heat conduction efficiency, reduce the temperature transfer delay caused by the small contact area, and at the same time avoid uneven heating of the top surface of the heat-conducting component 32, thereby improving the accuracy of temperature measurement and control.

[0095] In one embodiment of this disclosure, reference is made to Figure 4 and Figure 6A radially outwardly extending protrusion 335 is provided on the bracket 33. A limiting member 24 for cooperating with the protrusion 335 is provided in the movable cavity 22. When in the second position, the protrusion 335 is configured to abut against the limiting member 24 under the action of the elastic member 4. Specifically, the protrusion 335 can be provided on the upper bracket 3301 or the lower bracket 3302, and it can be integrally formed with the bracket 33, protruding radially outward relative to the main body of the bracket 33. At the position corresponding to the protrusion 335, a radially inwardly extending limiting member 24 is provided on the inner wall of the movable cavity 22, which is used to axially limit the temperature measuring module 3. When in the second position, the protrusion 335 tightly abuts against the end face of the limiting member 24 under the pre-pressure of the elastic member 4, thereby forming an axial limit. The limiting member 24, by abutting against the protrusion 335, limits the maximum rising height of the temperature measuring module 3 in the second position, preventing the elastic member 4 from excessively lifting and causing the temperature measuring module 3 to fall out of the active cavity 22, thereby improving the structural safety of the cooking equipment.

[0096] In one embodiment of this disclosure, reference is made to Figure 6 and Figure 7 The support 33 has a radially outwardly extending extension 336. A mating groove 3361 is formed on the side of the extension 336 away from the heat-conducting component 32. An abutment portion 25 is formed on the inner wall of the movable cavity 22. The elastic element 4 is a spring sleeved on the support 33, configured to be pre-compressed between the mating groove 3361 and the abutment portion 25. Specifically, the extension 336 can be provided on the upper support 3301, integrally formed with the upper support 3301, and protruding radially outward relative to the main body of the upper support 3301. An annular mating groove 3361 can be formed on the extension 336, and an annular abutment portion 25 can be provided on the movable cavity 22. The spring sleeved on the support 33 can be pre-compressed between the mating groove 3361 and the abutment portion, and the spring is in a pre-compressed state in its natural state.

[0097] The mating groove 3361 and the abutment part 25 provide precise upper and lower positioning for the spring, preventing lateral displacement or detachment during extension and retraction, and ensuring smooth movement of the temperature measuring module 3. The pre-compressed spring ensures that the temperature measuring module 3 can quickly return to the second position when the pot body 1 is removed. Furthermore, when the pot body 1 is placed, only the pre-compressed force is needed to push the temperature measuring module 3 down, without requiring excessive pressure, thus adapting to pot bodies 1 of different weights. Further, the spring can be made of a high-temperature resistant material, thereby adapting to the high-temperature environment inside the heating base 2 and preventing the spring's elasticity from weakening due to prolonged high temperatures.

[0098] Specifically, refer to Figure 14The abutment 25 and the limiting member 24 can be of the same structure. For example, it can be a flange provided on the inner wall of the movable cavity 22. The upper end face of the flange can serve as the abutment 25 abutting against the lower end of the spring, and the lower end face of the flange can serve as the limiting member 24 cooperating with the protrusion 335. This simplifies the internal structure of the movable cavity 22, reduces the number of parts, and improves the compactness of the internal structure of the heating base 2.

[0099] The design of the temperature measuring module 3 being movably mounted on the heating base 2 via the elastic element 4 creates a dynamic fit, ensuring that the heat-conducting component 32 of the infrared temperature measuring module 3 can tightly adhere to the bottom surface of the pot body 1. However, this movable assembly inevitably creates gaps on the bearing surface 21. Specifically, refer to... Figure 12 A through hole 211 communicating with the movable cavity 22 is provided on the bearing surface 21. The end of the temperature measuring module 3 adjacent to the pot body 1 (i.e., the heat-conducting component 32) is constructed to protrude from the through hole 211, thus protruding from the bearing surface 21 for easy contact with the pot body 1. Since the temperature measuring module 3 needs to move freely up and down along the through hole 211, it cannot completely fit with the inner wall of the through hole 211, and a sufficient fitting gap is usually required. (Reference) Figure 4 The temperature measuring module 3 and the through hole 211 form a liquid inlet 51. Liquid on the bearing surface 21 (such as soup or oil flowing down the side wall of the pot body 1) will flow into the active cavity 22 from the liquid inlet 51 and then into the heating base 2, causing the internal structure of the heating base 2 to be contaminated. This may cause component corrosion, shorten the equipment life, and even pose a risk of fire.

[0100] To solve the above problems, refer to Figure 3 , Figure 4 and Figure 12 The cooking apparatus of this disclosure also includes a drain channel, which is disposed on the heating base 2 and configured to communicate with the liquid inlet 51. External liquid is configured to be discharged through the liquid inlet 51 and the drain channel. Specifically, one end of the drain channel is connected to the liquid inlet 51, and the other end extends to the edge or bottom of the heating base 2. Liquid flowing into the liquid inlet 51 can be discharged out through the drain channel, for example, onto a kitchen countertop, thereby preventing it from seeping into the internal component area of ​​the heating base 2. By providing a drain channel, this disclosure guides the liquid flowing into the liquid inlet 51 to be discharged outward. The liquid can only flow along the drain channel, preventing it from spreading throughout the heating base 2, protecting core components such as the coil assembly 29 and circuits from corrosion by oil and broth, and extending the service life of the cooking apparatus.

[0101] In one embodiment of this disclosure, reference is made to Figure 12The heating base 2 has a liquid outlet 54 at its bottom. Under gravity, liquid from the inlet 51 flows through the drain channel to the outlet 54, thus draining it outside the heating base 2. Specifically, the outlet 54 is connected to the end of the external drain channel 53 of the drain channel. Liquid entering the drain channel flows naturally to the outlet 54 under gravity and drips directly onto the kitchen countertop. Users can also place a drip collection box under the outlet 54 for easier cleaning. This allows the drain path to reach the countertop directly, avoiding stagnation inside the cooking equipment. The entire draining process relies solely on gravity, eliminating the need for additional power components, thus reducing equipment costs and failure rates.

[0102] In one embodiment of this disclosure, reference is made to Figure 14 The heating base 2 is provided with a first sidewall 261 and a second sidewall 262 in an annular shape. The second sidewall 262 is located outside the first sidewall 261. The drainage channel includes an annular flow channel 52 formed by the second sidewall 262 and the first sidewall 261. For example... Figure 4 As shown, the annular flow channel 52 is configured to be located below the liquid inlet 51. Specifically, the liquid inlet 51 formed by the temperature measuring module 3 and the through hole 211 is annular, so the annular flow channel 52 can be set to the same annular shape as the liquid inlet 51; the annular gap between the first sidewall 261 and the second sidewall 262 forms the annular flow channel 52, and the top opening of the annular flow channel 52 faces directly below the liquid inlet 51, thereby allowing the liquid flowing in from the liquid inlet 51 to fall directly into the annular flow channel 52 under the action of gravity.

[0103] The annular flow channel 52 can receive liquid flowing in from the inlet 51 at 360°, preventing leakage and improving the liquid collection rate. The annular flow channel 52 may have a certain depth to ensure sufficient volume for temporary liquid storage, thereby dealing with situations where a large amount of liquid overflows in a short period of time and preventing liquid overflow from contaminating the interior of the heating base 2. In addition, the first sidewall 261 isolates the annular flow channel 52 from the inner active cavity 22, and the second sidewall 262 isolates the flow channel from the outer coil assembly 29, thereby forming a physical barrier and further reducing the risk of leakage.

[0104] In one embodiment of this disclosure, such as Figure 4As shown, the temperature measuring module 3 has a radially outwardly extending extension 336 located on its side wall below the liquid inlet 51. As mentioned earlier, the extension 336 can be a structure installed on the side wall of the support 33. The free end of the extension 336 is configured to extend outward to the annular flow channel 52. Liquid flowing in from the liquid inlet 51 is guided into the annular flow channel 52 via the extension 336. Specifically, the extension 336 is located below the liquid inlet 51 and above the annular flow channel 52. The extension 336 serves as a guide, allowing liquid flowing from the liquid inlet 51 to slide along its surface into the annular flow channel 52, preventing it from flowing downward or climbing upward along the side wall of the support 33.

[0105] This disclosure provides an extension 336 that protrudes laterally from the sidewall of the support 33, thereby intercepting liquid climbing up the sidewall of the support 33 (due to capillary effect or churning vibration) and guiding the liquid into the annular flow channel 52. The free end of the extension 336 extends into the annular flow channel 52, preventing liquid from leaking out from the gap between the support 33 and the flow channel, ensuring that the liquid can accurately enter the flow channel, and improving the reliability of the flow guidance.

[0106] In one embodiment of this disclosure, reference is made to Figure 4 The annular flow channel 52 has a bottom end face, and the drainage channel also includes an external drainage channel 53 connected to the bottom end face through a connecting port. The bottom end face of the annular flow channel 52 is constructed as a slope, and the connecting port is located at the lowest point of the slope. Specifically, the slope can be inclined towards a fixed position along the circumference of the annular flow channel 52, thereby ensuring that the liquid can flow naturally by gravity and converge to the connecting port opened at the lowest point of the slope. One end of the external drainage channel 53 is connected to the connecting port, and the other end extends downward along the side wall of the heating base 2 to below the edge of the heating base 2, forming a liquid outlet 54 from which the liquid can be discharged from the heating base 2.

[0107] This disclosure utilizes gravity to draw liquid towards the lowest connecting opening by setting the bottom end face of the annular flow channel 52 as a slope, thus preventing the formation of dead zones and liquid accumulation at the bottom of the annular flow channel 52, which reduces the likelihood of bacterial growth over long-term use. Furthermore, guided by the slope, the liquid can smoothly flow into the external drainage channel 53, which extends vertically. The liquid flows spontaneously solely by gravity throughout the entire flow process, resulting in low flow resistance and eliminating the need for an active drainage device such as a pump, thereby reducing drainage costs.

[0108] In one embodiment of this disclosure, reference is made to Figure 4In the radially outward direction of the extension 336, the top end face of the extension 336 is configured to extend downward at an angle. Liquid flowing from the inlet 51, after landing on the top surface of the extension 336, will quickly slide towards the annular flow channel 52 along the inclined direction, without accumulating on the surface of the extension 336. The inclined top surface provides a downward flow tendency for the liquid, shortening the residence time of the liquid in the extension 336 and preventing the liquid from adhering to the surface of the extension 336 due to viscosity (such as grease). Under the guiding effect of the top end face of the extension, the liquid can flow precisely into the annular flow channel 52, avoiding contamination to other areas.

[0109] In one embodiment of this disclosure, reference is made to Figure 4 The sidewall of the extension 336 is configured to extend into the annular flow channel 52. A flange-like sidewall structure is formed on the outer side of the extension 336, extending downwards and penetrating deep into the annular flow channel 52. This creates a structure where the sidewall of the extension 336 encloses the inner opening of the flow channel, preventing liquid from leaking into the movable cavity 22 through the gap between the extension 336 and the first sidewall 261. The extension 336 both prevents liquid from climbing upwards and intercepts liquid leakage into the movable cavity 22, forming a two-way leak-proof protection.

[0110] In one embodiment of this disclosure, the first sidewall 261 is configured to enclose the movable cavity 22, and the temperature measuring module 3 is configured to cooperate with the movable cavity 22, such as... Figure 7 As shown, a mating groove 3361 for engaging with the first sidewall 261 is provided on the side of the extension 336 away from the pot body 1. Specifically, refer to... Figure 4 The top of the first sidewall 261 can be inserted into the mating groove 3361 to form a nested fit, thereby initially preventing the liquid in the annular flow channel 52 from entering the movable cavity 22. In addition, the mating groove 3361 provides radial positioning for the first sidewall 261, which can ensure that the movable cavity 22 and the annular flow channel 52 are always coaxial.

[0111] Further, refer to Figure 4When the temperature measuring module 3 moves to the first position, the mating groove 3361 presses against the first side wall 261 to seal the passage between the drain channel and the movable cavity 22. Specifically, when the pot body 1 is placed on the heating base 2, the gravity of the pot body 1 overcomes the spring preload and pushes the temperature measuring module 3 downward to the first position; at this time, the mating groove 3361 of the extension 336 is tightly pressed against the top of the first side wall 261, with no gaps between the mating surfaces, completely sealing the passage between the drain channel (i.e., the annular flow channel 52) and the movable cavity 22, preventing liquid from entering the movable cavity 22. Thus, the sealing state can be automatically switched depending on whether the pot body 1 is placed on the heating base 2. When the pot body 1 is placed, it is in cooking condition, and the risk of overflow is high, so a complete seal is required; while when the pot body 1 is removed (for cleaning / idleness), the risk of overflow is low, and only a basic seal is needed. The sealing switching process does not require additional control by the user and is completed automatically as the pot body 1 is placed and removed, conforming to user habits and eliminating operational burden.

[0112] As mentioned above, the protrusion 335 on the bracket 33 and the limiting member 24 in the movable cavity 22 are used to limit the temperature measuring module 3 in the second position, which can limit the maximum rising height of the temperature measuring module 3 in the second position and prevent the elastic member 4 from excessively pushing up and causing the temperature measuring module 3 to fall out of the movable cavity 22. In the first position, the temperature measuring module 3 also needs to be limited. In this embodiment, the mating groove 3361 on the bottom surface of the extension 336 is not only used to seal with the first side wall 261, but also serves as a mechanical limiting structure for the temperature measuring module 3 in the first position.

[0113] Specifically, the vertical length of the first sidewall 261 is precisely matched with the depth of the mating groove 3361 and the preset descent stroke of the temperature measuring module 3. When the pot body 1 is placed on the heating base 2, the pot body 1 pushes the temperature measuring module 3 downward along the movable cavity 22 until the bottom end face of the mating groove 3361 is tightly abutted against the top end face of the first sidewall 261. At this time, the temperature measuring module 3 reaches the first position and cannot continue to move downward. This disclosure, through the abutment limit between the mating groove 3361 and the first sidewall 261, can strictly control the maximum descent stroke of the temperature measuring module 3, preventing the temperature measuring module 3 from excessively descending and squeezing the components at the bottom of the movable cavity 22 due to the excessive weight of the pot body 1 or the user pressing the pot body 1, or causing the spring to be over-compressed and fail. This structurally protects the service life of the temperature measuring module 3 and the elastic element 4.

[0114] In one embodiment of this disclosure, reference is made to Figure 6When in the second position, the free end of the first sidewall 261 is configured to be located within the mating groove 3361. This provides a certain sealing allowance, which can accommodate minor displacements of the temperature sensing module 3, preventing the mating groove 3361 from detaching from the first sidewall 261 due to displacement. This ensures the seal does not fail, improves the tolerance of the sealing structure, and eliminates assembly errors. Furthermore, even without the pot body 1 on the heating base 2, there is still a possibility of liquid entering through the liquid inlet 51. This disclosure maintains a nested seal in the second position, thereby continuously protecting the temperature sensing component from contact with liquid.

[0115] For example, after cooking is finished and the user has lifted the pot 1 and raised the temperature measuring module 3 to the second position, the user can then wipe the heating base 2 clean. Therefore, a small amount of liquid may still seep into the liquid inlet 51. The liquid will first fall onto the top end face of the extension 336 and be guided to the annular flow channel 52, thereby achieving external discharge. During this process, although the mating groove 3361 is not sealed to the first side wall 261, the small amount of liquid allows it to be smoothly guided without climbing the wall and flowing into the active cavity 22.

[0116] In one embodiment of this disclosure, reference is made to Figure 12 The heating base 2 includes an upper tray 201 and a lower tray 202. A through hole 211 is provided on the upper tray 201, and a first side wall 261 and a second side wall 262 are provided on the lower tray 202. The second side wall 262 is configured to extend upward to abut against the upper tray 201. Specifically, a bearing surface 21 is formed on the top of the upper tray 201, and the through hole 211 is opened at the center of the upper tray 201. The lower tray 202 is a bottom support structure, and the first side wall 261 and the second side wall 262 are integrally formed on the lower tray 202, that is, the movable cavity 22 is located on the lower tray 202. The upper tray 201 and the lower tray 202 are fixedly installed together to form the heating base 2. This disclosure separates the upper tray 201 and the lower tray 202, allowing them to be processed separately, realizing modular production, reducing processing difficulty, and improving production efficiency.

[0117] In one embodiment of this disclosure, reference is made to Figure 3The coil assembly 29 is configured to be disposed between the upper tray 201 and the lower tray 202, with its top surface fitting against the bottom surface of the upper tray 201 and its bottom surface fitting against the top surface of the lower tray 202, thereby forming a relatively enclosed heating area. Specifically, in actual assembly, the coil assembly 29 can be installed at the bottom of the upper tray 201 or at the top of the lower tray 202; this disclosure does not limit this. The structures on the upper tray 201 and the lower tray 202 (such as the first sidewall 261 and the second sidewall 262) can isolate the coil assembly 29 from the detection assembly 31. The high-temperature heat generated by the coil assembly 29 during operation can be blocked by the trays, preventing the ambient temperature around the infrared thermometer 311 from becoming too high, thereby extending the life of the infrared thermometer 311. In addition, the relatively enclosed heating area can reduce heat loss, improve heating efficiency, and prevent external dust and oil from entering the coil assembly 29, thus preventing malfunctions.

[0118] In one embodiment of this disclosure, reference is made to Figure 13 An assembly groove 27 is provided on the upper tray 201 near the through hole 211. A first sealing element 28 is provided in the assembly groove 27. The second sidewall 262 is configured to abut against the assembly groove 27 of the upper tray 201 through the first sealing element 28. Specifically, an annular assembly groove 27 is provided on the upper tray 201 at the abutment point of the top of the second sidewall 262. The first sealing element 28 is embedded in the assembly groove 27. The first sealing element 28 can be a high-temperature resistant silicone sealing ring. When the upper and lower trays 202 are assembled, the top of the second sidewall 262 extends into the assembly groove 27 and squeezes the first sealing element 28, causing the sealing element to deform and fill the gap between the assembly groove 27 and the second sidewall 262, thereby achieving a seal at the joint between the upper tray 201 and the lower tray 202, ensuring the sealing of the flow channel and improving the reliability of drainage. The first seal 28 is made of an elastic material, which can completely fill the joint gap through deformation. Even if there are minor processing errors between the upper tray 201 and the lower tray 202, the first seal 28 can compensate for them, preventing liquid from leaking into the lower tray 202 from the joint.

[0119] In one embodiment of this disclosure, reference is made to Figure 13The upper tray 201 has a guide surface 212 on its bearing surface 21, which is configured to surround the through hole 211. The guide surface 212 extends downwards at an angle in the radially outward direction of the through hole 211. The guide surface 212 is annular, forming a raised, convex slope with a high center and low outer edges. During cooking, if soup or oil accidentally spills onto the bearing surface 21, the liquid, guided by gravity, flows away from the through hole 211 along the inclined direction of the guide surface 212, thus reducing the total amount of liquid entering the inlet 51 at the source. This allows the inlet 51 to only handle extremely large spills or situations where liquid flows directly into the inlet 51, thereby reducing the probability of liquid seeping into the interior of the cooking equipment.

[0120] In one embodiment of this disclosure, as previously described, the heat-conducting component 32 is configured as a sleeve structure, which is sleeved on the support 33 at one end adjacent to the pot body 1, such as... Figure 7 As shown, a second sealing element 34 is provided between the sleeve structure and the bracket 33. Specifically, the second sealing element 34 can be a high-temperature resistant silicone ring, which can be embedded in the gap between the sleeve and the bracket 33, thereby blocking the top leakage path and preventing water vapor, oil vapor, liquid and other dirt from seeping into the interior of the bracket 33 from the gap between the heat-conducting component 32 and the bracket 33, thus contaminating the detection component 31.

[0121] In one embodiment of this disclosure, reference is made to Figure 9 The heat-conducting component 32 includes a metal body, which includes a first surface 3201 for contacting the pot body 1 and a second surface 3202 facing the detection component 31. In the temperature detection scheme based on the principle of infrared radiation, the heat-conducting component 32 is the core medium connecting the pot body 1 and the detection component 31. Its first surface 3201 conducts heat through contact with the pot body 1, making the overall temperature of the metal body consistent with that of the pot body 1. Then, it emits infrared radiation to the infrared thermometer 311 through the second surface 3202, and the detection component 31 calculates the temperature by receiving the radiation. To balance thermal conductivity and structural strength, the metal body is preferably made of aluminum or copper. These metals have good thermal conductivity, but their natural thermal emissivity is extremely low, which is far from meeting the requirement of stable high emissivity for infrared temperature measurement.

[0122] To address the aforementioned issues, a processing layer is provided on the second surface 3202, with the thermal emissivity of the processing layer exceeding that of the metal body. Specifically, the processing layer can be implemented using three main approaches: First, etching, sandblasting, or other processes can be performed on the second surface 3202 to increase its surface area and thus improve its emissivity. Second, chemical treatments (such as anodizing) can be used to treat the second surface 3202, thereby increasing its emissivity. Third, a high-emissivity coating can be applied to the second surface 3202 to further enhance its emissivity. This processing layer significantly increases the emissivity of the second surface 3202 of the metal body, for example, from below 0.1 to above 0.9. This results in a more stable distribution of radiant energy received by the detection component 31, thereby improving the accuracy of temperature measurement and control and reducing measurement errors.

[0123] In one specific embodiment of this disclosure, the treatment layer includes a sandblasting layer configured to adhere to the second surface 3202 of the metal body. Specifically, sandblasting is a workpiece surface treatment process that uses compressed air as power to form a high-speed jet that propels abrasive materials (copper ore sand, quartz sand, corundum, iron sand, sea sand, etc.) at high speed onto the second surface 3202 of the metal body. This increases the roughness and surface area of ​​the second surface 3202, thereby improving its emissivity. Sandblasting alters the microstructure of the metal surface through physical means, eliminating the need for chemical coatings and avoiding coating decomposition and peeling at high temperatures, resulting in a more durable structure. Furthermore, sandblasting is a mature and low-cost process that can be mass-produced on metal bodies, making it suitable for large-scale production.

[0124] Furthermore, the treatment layer includes a blackbody coating, which is attached to the sandblasted layer. Specifically, the blackbody coating is applied to the surface of the sandblasted layer using a spraying process. The material of the blackbody coating can be selected from one of the following: ceramic oxide, silicon dioxide, ferric oxide, aluminum oxide, zirconium oxide, silicon carbide, and carbon nanotubes. The rough surface of the sandblasted layer increases the adhesion between the blackbody coating and the metal body, preventing the blackbody coating from peeling off or cracking during use, and significantly improving the bonding strength. The composite structure of the treatment layer combines the large surface area of ​​the sandblasted layer with the high emissivity of the blackbody coating, resulting in an emissivity of 0.95-0.98, close to that of an ideal blackbody (emissivity = 1). This allows the detection component 31 to directly and accurately calculate the temperature without complex emissivity compensation algorithms, simplifying the programming of the main control system.

[0125] In another specific embodiment of this disclosure, the treatment layer may also consist only of a blackbody coating. In this embodiment, the blackbody coating is directly attached to the second surface 3202 of the metal body. Directly spraying the blackbody coating onto the surface of the metal body can still significantly improve the emissivity. This solution omits the sandblasting process, simplifies the processing flow, and reduces production costs.

[0126] In one embodiment of this disclosure, as described above, the heat-conducting component 32 includes a cover portion 321 covering the opening end of the cover bracket 33, and the second surface 3202 of the cover portion 321 facing the detection component 31 is planar. It should be noted that this is not limited to the second surface 3202 being smooth, but rather more macroscopically defined as not being curved or arc-shaped. The planar design of the second surface 3202 allows infrared radiation to be uniformly emitted to the detection component 31 in the vertical direction, avoiding radiation scattering caused by curved surfaces, thereby improving the utilization rate of radiation energy. Furthermore, high planarity and coaxiality ensure stable radiation signals received by the detection component 31, avoiding localized differences in radiation intensity caused by surface unevenness or offset, further reducing temperature measurement errors. Moreover, the planar processing technology is simple, facilitating subsequent sandblasting and blackbody coating processes, ensuring uniform thickness of the treated layer.

[0127] In the temperature measurement module 3, the cover portion 321 of the heat-conducting component 32 is configured to emit infrared radiation towards the detection component 31. The relative size of the cover portion 321 and the detection component 31 is crucial in determining the temperature measurement accuracy. The receiving angle of the infrared thermometer 311 is denoted as α, which is usually a fixed value. If the size of the cover portion 321 is too small or too far from the detection component 31, the cover portion 321 cannot completely fill the receiving field of view of the detection component 31, resulting in the reception of some environmental clutter radiation, leading to a lower measured temperature and poor temperature control.

[0128] To solve the above problems, refer to Figure 8 The distance between the detection component 31 and the heat-conducting component 32 is denoted as L, and the diameter D of the covering part 321 is ≥ 2L*tan(α / 2). Figure 8As shown in the cross-sectional view, when the diameter of the covering portion 321 exactly fills the receiving field of view of the detection component 31, the area where the detection component 31 receives infrared radiation is an isosceles triangle with a base length of D, a height of L, and a vertex angle of α. Therefore, D = 2L * tan(α / 2). By limiting the diameter of the covering portion 321 to D ≥ 2L * tan(α / 2), it is ensured that the covering portion 321 completely fills the receiving field of view of the detection component 31, preventing environmental clutter radiation from entering. For the detection component 31, the entire area within its receiving angle is directly facing the covering portion 321 and will not hit the sidewall of the radiation cavity 331, thereby ensuring that the detection component 31 can collect sufficient data, thus improving detection accuracy. This disclosure provides a clear dimensional formula to provide a quantitative basis for the design of the heat-conducting component 32, avoiding problems such as incomplete or obstructed infrared field of view due to incorrect dimensional design of the heat-conducting component 32.

[0129] In a specific embodiment of this disclosure, L > 20 mm, and further, the temperature at the location of the detection component 31 is less than 75°C. Specifically, the temperature of the pot body 1 during operation is very high, reaching over 250°C, while the infrared thermometer 311 can withstand a relatively low operating temperature. Its operating environment is preferably below 75°C; otherwise, its lifespan and accuracy may be affected. Therefore, it is necessary to ensure that the distance L between the detection component 31 and the heat-conducting component 32 is large enough, thereby reserving sufficient cooling space, effectively isolating the high temperature of the heat-conducting component 32, and preventing the detection component 31 from aging due to overheating, thus extending its service life. The specific value of L can be adjusted according to the internal space of the heating base 2, with a minimum of 20 mm, so as to ensure that the temperature at the location of the detection component 31 is less than 75°C, avoiding drift in detection accuracy caused by high temperature. At the same time, L should not be too large, preferably L < 30 mm; otherwise, if the distance between the detection component 31 and the heat-conducting component 32 is too small, it may cause the infrared radiation to attenuate during propagation or be reflected on the inner wall of the radiation cavity 331, thereby reducing the measurement accuracy.

[0130] In one embodiment of this disclosure, the second surface 3202 of the cover portion 321 emits infrared radiation to the detection component 31 through the radiation cavity 331, and the detection component 31 receives the infrared radiation at an angle α ≥ 35°. Specifically, 35-45° is a common angle range for the infrared thermometer 311. This disclosure allows for the direct purchase of standardized infrared thermometers 311 without customization, thereby reducing production costs. The radiation receiving angle of the infrared thermometer 311 is determined by its lens field of view, and the cover portion 321 can be configured to be completely within the receiving range of the detection component 31.

[0131] In this embodiment, calculations using α = 35° (i.e., minimum α) and L = 20mm (i.e., minimum L) yield Dmin = 2L * tan(α / 2) = 12.61mm. Therefore, D > 12.61mm can be further specified. A D > 12.61mm dimension design simultaneously satisfies the distance requirement of L > 20mm and the receiving angle requirement of α, achieving full coverage of the radiation field of view without adjusting other dimensions, thus optimizing detection accuracy. Furthermore, a sufficiently large diameter D ensures that the contact area between the first surface 3201 of the covering portion 321 and the pot body 1 is sufficiently large (approximately greater than 125mm). 2 This improves the efficiency of heat conduction.

[0132] In one embodiment of this disclosure, the heat-conducting component 32 is configured as a sleeve structure, with the end face of the sleeve structure in contact with the pot body 1 having a thickness of 0.4-0.6 mm. If the sleeve structure is too thick, it may lead to a delay in heat transfer, and the heat-conducting component 32 may not be able to quickly conduct the temperature of the pot body 1 from the first surface 3201 to the second surface 3202, thereby causing a delay in temperature control. If the sleeve structure is too thin, it is prone to deformation after being heated, which may cause the first surface 3201 to not be able to fully fit and adhere to the bottom surface of the pot body 1. Preferably, in this embodiment, the thickness of the sleeve structure can be set to 0.5 mm to ensure a balance between heat conduction efficiency and structural strength.

[0133] This disclosure also provides a temperature measuring module 3, which can be used in the aforementioned cooking equipment, as well as in other equipment for temperature measurement and control, such as ovens, air fryers, bread makers, dryers, injection molding machines, constant temperature chambers, and heat therapy devices. The temperature measuring module 3 includes a detection component 31 and a heat-conducting component 32. The heat-conducting component 32 is used to contact the object to be measured to conduct the temperature of the object and emit infrared radiation to the detection component 31. The detection component 31 is configured to receive the infrared radiation emitted by the heat-conducting component 32 to detect the temperature of the heat-conducting component 32. The heat-conducting component 32 includes a metal body and a processing layer. The metal body includes a first surface 3201 for contacting the object to be measured and a second surface 3202 facing the detection component 31. The processing layer is located on the second surface 3202 of the metal body, and the thermal emissivity of the processing layer is greater than that of the metal body.

[0134] The temperature measurement module 3 of this disclosure can measure the temperature of the object to be measured from a distance using infrared thermometry. The first surface 3201 of the metal body contacts the object to be measured, making the overall temperature of the metal body consistent with that of the pot body 1. Then, infrared radiation is emitted to the detection component 31 through the second surface 3202. The detection component 31 calculates the temperature of the object to be measured by receiving the radiation. The second surface 3202 of this disclosure is provided with a processing layer, which greatly increases the emissivity of the second surface 3202 of the metal body. This makes the radiation energy received by the detection component 31 more stable, thereby improving the accuracy of temperature measurement and control and reducing temperature measurement errors.

[0135] This disclosure also provides a temperature measuring module 3, which can be used in the aforementioned cooking equipment, as well as in other equipment for temperature measurement and control. The temperature measuring module 3 includes a detection component 31 and a heat-conducting component 32. The heat-conducting component 32 is used to contact the object to be measured to conduct the temperature of the object and emit infrared radiation to the detection component 31. The detection component 31 is used to receive the infrared radiation emitted by the heat-conducting component 32 to detect the temperature of the heat-conducting component 32. The detection component 31 includes an infrared thermometer 311 and a shielding member 313. The infrared thermometer 311 is configured to receive the infrared radiation emitted by the heat-conducting component 32. The shielding member 313 is sleeved on the outer periphery of the infrared thermometer 311 and is configured to shield the magnetic field outside the infrared thermometer 311.

[0136] When magnetic field interference exists in the operating environment of the temperature measuring module 3, the shielding component 313 can shield the influence of the external magnetic field on the infrared thermometer 311, significantly attenuating the interference of the external magnetic field on the infrared thermometer 311, thereby ensuring the accuracy of the infrared thermometer 311 and thus ensuring temperature control precision. Furthermore, the shielding component 313 is fitted around the outer periphery of the infrared thermometer 311; its small size does not occupy much space to achieve the shielding effect. The annular structure of the shielding component 313 completely surrounds the infrared thermometer 311, resulting in a higher magnetic field attenuation rate and more comprehensive anti-interference effect compared to a semi-enclosed shielding component 313. This disclosure uses physical shielding to eliminate interference, thus eliminating the need for complex software algorithms, reducing the computing power burden on the main control system, and simultaneously coping with sudden strong magnetic fields, resulting in stronger anti-interference stability.
