[0002] The intelligentization of kitchen appliances has become an important development trend. As a core device in the modern kitchen, the intelligent control function of integrated cooktops relies on the accurate and real-time detection and analysis of oil fumes generated during cooking. However, in practical applications, the bottleneck of oil fume detection lies in the reliability of long-term operation.

[0003] When an integrated cooktop is working, the inhaled fumes carry heat, and the motor itself is a heat source. Within the confined space of the upper-level computer components, if the heat generated by the motor cannot be dissipated in time, it will exacerbate the localized high-temperature environment, further affecting the stability of sensors and electronic control components. Traditional heat dissipation solutions, such as adding independent cooling fans or complex air ducts, are often difficult to implement due to limited space, or may increase cost and power consumption.

[0038] The present invention will be further explained in conjunction with the embodiments:

[0039] The core technical problem faced by the technical solution of this application embodiment stems from the inventor's accurate understanding of the prior art. Therefore, how to improve the stability and service life of oil fume detection is a technical problem that the inventor urgently needs to solve.

[0040] It should be noted that the embodiments do not constitute a limitation on the scope of protection of the claims of this utility model. All technical solutions that can be reasonably expected by those skilled in the art based on the technical concepts provided / proved by the embodiments should be covered within the scope of protection of the claims of this utility model.

[0041] The specific implementation examples are detailed below:

[0042] Please refer to the attached document. Figures 1-5This embodiment provides a fan cooling structure, which includes a horizontally arranged fan 3.1 located at the fume inlet for introducing the fumes to be detected and analyzed during the operation of the integrated stove. The fan 3.1 is typically a cross-flow fan with a horizontally arranged impeller, capable of axially drawing in fumes and radially expelling them using centrifugal force, thus efficiently transporting the fumes. Simultaneously, the cooling structure also includes a cooling impeller 3.2, whose rotation generates a cooling airflow directed towards the motor 3.3. The motor 3.3 is the driving component, simultaneously driving both the fan 3.1 and the cooling impeller 3.2. Specifically, the drive shaft of the motor 3.3 directly drives the impeller of the fan 3.1 and the cooling impeller 3.2 to rotate together. This design allows the function of the fan 3.1 in introducing fumes and the cooling function of the cooling impeller 3.2 to be performed synchronously, ensuring that while the motor 3.3 is operating, the cooling impeller 3.2 can promptly generate a cooling airflow to cool the motor 3.3, effectively preventing the motor 3.3 from overheating and being damaged due to prolonged operation. Furthermore, since the heat dissipation impeller 3.2 does not require an additional independent power unit, such as a second motor or a complex transmission mechanism, the entire heat dissipation structure becomes very simple, with fewer parts and easy assembly, significantly saving installation space. This is especially advantageous for the internal installation of the host computer components, which are already in short supply of space, allowing the structure to be compactly integrated into a limited space.

[0043] For more details, please refer to the appendix. Figure 4 The motor 3.3 drives the cooling impeller 3.2 to rotate via an extension 3.31 of its drive shaft. The drive shaft of the motor 3.3 extends to one side, forming the extension 3.31, which is fixedly connected to the center hole of the cooling impeller 3.2 via a key, interference fit, or fasteners. When the motor 3.3 is running, the drive shaft and its extension 3.31 rotate together, directly driving the cooling impeller 3.2 to rotate at the same speed. This direct drive method via the drive shaft extension 3.31 is compact, has a short transmission chain, and high power transmission efficiency. It avoids the slippage, wear, and energy loss problems that may occur with intermediate transmission components such as belts and gears, making the rotation of the cooling impeller 3.2 more reliable, stable, and efficient, ensuring a continuous and stable supply of cooling airflow.

[0044] For further implementation methods, please refer to the appendix. Figures 1-5The fan 3.1, cooling impeller 3.2, and motor 3.3 are arranged side-by-side along the axial direction of the drive shaft of motor 3.3. Along the axial direction of the drive shaft, the fan 3.1, motor 3.3, and cooling impeller 3.2 are arranged sequentially. This axially parallel arrangement makes the entire fan cooling structure very compact. All major components are arranged along the axial direction of the drive shaft, maximizing the use of axial space and avoiding excessive volume in the radial direction, resulting in a more regular structural outline. This compact layout not only saves valuable internal space but also minimizes the connection and power transmission paths between components, facilitating rapid assembly and positioning on the production line. It also facilitates the disassembly and replacement of individual components during subsequent maintenance, making it particularly suitable for installation within confined spaces in host computer components.

[0045] For further implementation methods, please refer to the appendix. Figure 3 The system also includes a motor bracket 3.4. The motor 3.3 is mounted on the motor bracket 3.4, specifically on the side of the motor bracket 3.4 away from the fan 3.1. The motor bracket 3.4 is typically made of metal or high-strength plastic, and its main body has mounting holes or snap-fit ​​structures to secure the motor 3.3. The outer contour of the motor bracket 3.4 allows it to fit tightly against the inner wall of the upper computer assembly (such as the fume analysis chamber a) when installed, forming a sealed structure. This sealed structure separates the internal space of the chamber: one side is the area through which the fume introduced by the fan 3.1 flows, and the other side is the area where the motor 3.3 is located. This sealing barrier effectively prevents the fume and its oil and impurities from penetrating to the side where the motor 3.3 is located, thus isolating the fume introduced by the fan 3.1 from the motor 3.3. This provides a solid installation foundation for motor 3.3, ensuring that its vibration is minimized during operation. The sealed structure also protects motor 3.3, preventing oil fumes from directly adhering to the surface of motor 3.3 or entering its interior, which could lead to failures such as reduced insulation performance, corrosion, and short circuits. This significantly improves the reliability and service life of motor 3.3 in harsh oil fume environments.

[0046] Furthermore, an electronic control area b is located on the side of the motor 3.3 away from the motor bracket 3.4. This electronic control area b contains various electronic components required for the integrated stove to achieve intelligent control functions, such as the main control circuit board, power drive chip, and sensor signal processing circuits. These electronic components are typically concentrated on one or more circuit boards and located behind the motor 3.3 (relative to the direction in which the fan 3.1 introduces the fumes). Because the sealed structure of the motor bracket 3.4 isolates the fumes from the motor 3.3 and the electronic control area b, the precision electronic components within the electronic control area b are protected from fumes contamination, preventing short circuits, signal interference, or component corrosion caused by oil buildup. Simultaneously, the cooling airflow generated by the heat dissipation impeller 3.2, after passing over the surface of the motor 3.3, also carries away the heat generated by the electronic components within the electronic control area b during operation. This provides a second layer of heat dissipation for the electronic control area b, preventing performance degradation, parameter drift, or premature failure of electronic components due to prolonged high-temperature operation, further improving the stability and reliability of the control system.

[0047] For further implementation methods, please refer to the appendix. Figure 4 The cooling impeller 3.2 has several cooling blades evenly and spaced along the circumference of the hub. Each cooling blade includes a pushing surface 3.21 that propels the gas and a deflecting surface 3.22 that restricts the gas flow away from the motor 3.3. The pushing surface 3.21 is the side of the blade facing the incoming airflow and is responsible for doing work on the air when the impeller rotates, pushing the air to generate an airflow towards the motor 3.3. The deflecting surface 3.22 is located on the leeward side of the pushing surface 3.21, positioned along the flow path of the gas propelled by the pushing surface 3.21, serving as a guide and constraint. When the impeller rotates, the pushing surface 3.21 propels the air, while the deflecting surface 3.22 acts as a barrier, restricting the airflow to other directions (especially away from the motor 3.3), forcing the airflow to concentrate more towards the direction of the motor 3.3. This blade design makes the cooling airflow generated by the heat dissipation impeller 3.2 more concentrated and directional, reducing airflow scattering and energy loss during the conveying process, thereby improving the heat dissipation effect on the motor 3.3 and ensuring cooling efficiency.

[0048] For further implementation methods, please refer to the appendix. Figure 4A guide angle 3.211 is provided at the outer end of the thrust surface 3.21 (i.e., the blade tip, the end away from the hub). The guide angle 3.211 can be a smooth transition structure formed by chamfering, rounding, or cutting at a specific angle. When the cooling impeller 3.2 rotates at high speed, the blades push the air to form a centrifugal airflow, which moves from the central area of ​​the impeller to the outer periphery. At the outlet area where the airflow leaves the blade tip, the guide angle 3.211 allows the airflow to expand more fully, reducing the eddies and turbulence generated by the airflow, thereby reducing the resistance at the airflow outlet. This expanded centrifugal airflow outlet structure makes the gas flow smoother, and the cooling impeller 3.2 needs to overcome less resistance when pushing the air. Therefore, the torque and power required for the motor 3.3 to drive the cooling impeller 3.2 are also reduced. The reduction in energy consumption of the motor 3.3 directly leads to a decrease in the heat generated during its operation, reducing the heat dissipation burden from the source, and also improving the energy efficiency ratio of the entire fan cooling system, achieving energy-saving operation.

[0049] This embodiment also provides a host computer component; please refer to the appendix. Figure 1 , 2 5. This component includes a fume hood 4 and an oil fume analysis chamber a disposed inside the fume hood 4. The fume hood 4 is used to collect oil fumes generated during cooking, and the oil fume analysis chamber a is the core cavity for oil fume detection and analysis. An oil fume inlet is provided on its wall, which is connected to the oil fume channel of the fume hood 4. Inside the oil fume analysis chamber a, a fan cooling structure as described in any of the above embodiments is provided. Specifically, a fan 3.1 is installed aligned with the oil fume inlet, responsible for introducing the oil fume to be detected into the analysis chamber; the motor 3.3 and the cooling impeller 3.2 are fixed to the cavity and sealed via a motor bracket 3.4. Due to the adoption of the above-mentioned fan cooling structure, during operation, the motor 3.3 driving the fan 3.1 and the nearby electrical control area b can receive timely and effective air cooling, avoiding problems such as motor performance degradation, insulation aging, or failure of control electronic components caused by prolonged high-temperature operation. Meanwhile, the compact integrated design makes the overall structure of the host computer components reasonable, occupies little space, and operates more stably and reliably, thus ensuring the continuous and accurate operation of the integrated stove's intelligent oil fume detection function.

[0050] Furthermore, as a cross-flow fan, when its impeller rotates, the fumes are axially drawn in, then accelerated and subjected to centrifugal force inside the impeller, and finally thrown out from the radial outlet of the fan. The thrown-out fumes are guided and output to a specially designed guide 2, which is an arc-shaped plate. When the high-temperature fumes come into contact with the relatively cool surface of the guide 2, some of the fumes condense into liquid oil droplets. The guide 2 collects these condensed oil droplets and transports them to the detection area of ​​the detection sensor 1 located below it. The detection sensor 1 is a humidity sensor. This design provides the detection sensor 1 with a stable and continuous sample of liquid oil droplets, facilitating accurate detection of its humidity, thereby achieving direct and effective monitoring of the fumes' condition and providing a reliable input signal for the control of the integrated stove.

[0051] For further details, please refer to the appendix. Figure 6 The guide component 2 is composed of a diffuser wall 2.1, a guide wall 2.2, and a condenser wall 2.3, arranged sequentially according to the flow order of the fumes. The diffuser wall 2.1 forms a gradually narrowing fume flow space at the inlet of the fan 3, which helps increase the pressure of the fumes and reduce their flow velocity, thus ensuring airflow. The guide wall 2.2 has a curved surface conforming to the flow direction of the fumes. This surface can be adapted to the outer surface contour of the fan, avoiding the generation of eddies and reducing the flow resistance of the fumes, so as not to obstruct the inflow of subsequent fumes. After being output by the fan 3, the fumes form a centrifugal flow state, which facilitates the agglomeration and condensation of fine oil droplets. The condenser wall 2.3 has a condensation structure, providing a basis for the condensation of the fumes. The detection sensor 1 is located below the condenser wall 2.3 to detect the oil droplets conducted down from the condenser wall 2.3. This design ensures effective condensation and detection of oil droplets by gradually changing the state of the fumes, further improving the accuracy of detection and the service life of the sensor.

[0052] In some embodiments, multiple sets of condensation protrusions 2.31 are formed on the condensation wall 2.3. These condensation protrusions 2.31 can be through holes to facilitate the accumulation and guidance of oil fumes. The design of the condensation protrusions 2.31 helps to achieve uniform distribution of oil fumes on the condensation wall 2.3, further improving the condensation efficiency of oil droplets. This design ensures that oil droplets can condense uniformly on the condensation wall 2.3, improving the detection accuracy of the detection sensor 1;

[0053] An oil-collecting flange 2.32 is provided on the side of the condensing wall 2.3 facing the detection sensor 1. This flange 2.32 has a curved surface that guides oil droplets to the detection sensor 1. This curved surface has an arc-shaped structure that bends towards the lower part of the condensing wall 2.3, causing the lower end of the flange 2.32 to taper relative to the upper end, thereby improving the oil droplet collection effect. The flange 2.32 is designed to guide the condensed oil droplets to the detection sensor 1, ensuring that the oil droplets can smoothly reach the detection sensor 1 for detection. This design further improves the oil droplet collection efficiency, ensuring that the detection sensor 1 can receive enough oil droplets for accurate detection.

[0054] In a further embodiment, an oil-collecting flange 2.32 is provided on each side of the condensation wall 2.3. The presence of oil-collecting flanges 2.32 on both sides effectively guides oil droplets, ensuring that they do not leak from the sides of the condensation wall 2.3, further improving oil droplet collection efficiency. This design ensures that the detection sensor 1 can receive more oil droplets, improving detection accuracy.

[0055] This embodiment also provides an integrated cooktop equipped with the aforementioned host computer component. This host computer component is integrated into the cooktop body, located within the smoke collection hood module above the cooktop. Due to the integration of the host computer component, which possesses efficient heat dissipation and anti-pollution capabilities, this integrated cooktop can operate stably for extended periods in harsh environments with high temperatures and high oil fumes. This overcomes the problem in traditional integrated cooktops where sensors are prone to failure or inaccurate measurements due to oil buildup and high temperatures, ultimately improving the overall performance, reliability, and user experience of the product.
