Abstract
Description
Technical Field
[0001] This invention belongs to the field of cooking parameter detection technology for integrated stoves, specifically relating to a host computer component and an integrated stove that improves the service life of the detection device. Background Technology
[0002] As a core appliance in modern kitchens, integrated cooktops rely on real-time, accurate detection of cooking fumes for their intelligent control functions (such as automatic fan speed adjustment). However, existing integrated cooktop intelligent control applications have significant limitations, primarily because the detection sensors are exposed to harsh environments of high temperatures and high oil content for extended periods, leading to the following problems:
[0003] Oil adhesion problem: Oil particles in cooking fumes easily adhere to the sensor surface, gradually forming an oil film that leads to sensor signal distortion or complete failure; High temperature damage problem: High-temperature cooking fumes (usually >150℃) continuously act on the internal electronic components of the sensor, causing component performance degradation, manifested as irreversible damage such as signal drift and unstable output, as well as a reduction in service life; Detection method defects: Currently, the commonly used technology is direct analysis of flue gas components. This method is easily affected by factors such as ambient temperature and humidity and airflow disturbances, making it difficult to capture changes in flue gas concentration in a timely manner under complex working conditions.
[0004] The aforementioned problems collectively lead to a decrease in sensor detection accuracy, causing frequent response delays, incorrect gear adjustments, or control failures in the intelligent gear control of integrated cooktops. Therefore, there is an urgent need for a fume detection structure that can avoid the wear and tear on the detection sensor caused by cooking fumes, obtain more stable detection results, and thus improve the sensor's lifespan and detection stability.

[0055] The present invention will be further explained in conjunction with the embodiments:
[0056] 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 accuracy and service life of oil fume detection is a technical problem that the inventor urgently needs to solve.
[0057] It should be noted that the embodiments do not constitute a limitation on the scope of protection of the claims of this invention. 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 invention.
[0058] The specific implementation examples are detailed below:
[0059] Please refer to the attached document. Figures 1-5 This embodiment provides a host computer component for guiding the detection of cooking fumes, which includes a fume collection hood 4. Specifically, an oil fume analysis chamber a is provided inside the fume collection hood 4, and the oil fume analysis chamber a has an oil fume inlet. The oil fume analysis chamber a is equipped with a fan 3, a guide component 2 for guiding the flow of oil fumes, and a detection sensor 1 for detecting condensed oil droplets from the oil fumes. The fan 3 uses a centrifugal method to output the oil fumes to the guide component 2, which is responsible for conveying the condensed oil droplets to the detection sensor 1 below for detection. The innovation of this embodiment lies first in the selection of the detection object (the state of the oil fume). The detection object is the condensed droplets rather than the oil fume itself, and the detection result is humidity rather than the concentration of oil fumes. The oil fumes are first partially introduced into the oil fume analysis chamber a and condensed into oil droplets, and then the detection sensor 1 detects the humidity of these condensed oil droplets. The innovation of this technical solution is also reflected in the structural design based on the detection of liquid droplets. This design effectively avoids direct contact between oil fumes and the detection sensor 1, preventing the high temperature of the oil fumes from damaging the internal components of the detection sensor 1. It also prevents oil fumes from adhering to the surface of the detection sensor 1 and affecting its normal operation. Therefore, the implementation method of this embodiment has more accurate detection results and a longer service life, and the integrated stove can make more accurate feedback based on the detection results.
[0060] In a further embodiment, the guide 2 within the fume analysis chamber a 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, thereby ensuring airflow. The guide wall 2.2 has a curved surface conforming to the flow direction of the fumes, which can be adapted to the outer surface profile of the fan to avoid the generation of eddies and reduce 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.
[0061] In this embodiment, an oil-passing section 5 is provided below the fume analysis chamber a. The oil-passing section 5 includes a vertically arranged oil-passing channel 5.1 and an oil-passing hole 5.2 located at the lower end of the oil-passing channel 5.1. The oil fumes are collected into droplets by the guide member 2 and detected. Subsequently, the detected droplets and residual oil fumes are transported downward through the oil channel 5.1 and then discharged from the oil-passing section 5 after passing through the oil hole 5.2. More specifically, the oil-passing channel 5.1 is formed by the protruding part of the fume collection hood 4 and the back plate. The oil-passing channel 5.1 discharges the smoke and condensate collected in the fume analysis chamber a into the smoke extraction channel of the integrated stove through the aforementioned oil-passing hole 5.2.
[0062] In a further embodiment, an oil-collecting flange 2.32 is provided on the side of the condensation 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 condensation wall 2.3, causing the lower end of the flange 2.32 to taper relative to its 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.
[0063] 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.
[0064] 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;
[0065] As a preferred embodiment of this invention, see attached... Figure 6As shown, a collecting part 2.312 is provided on the condensing protrusion 2.31 to collect oil droplets in the fumes onto its surface and guide the fumes to flow separately to both sides. The collecting part 2.312 is a sloping surface that follows the direction of the fumes flow. A gathering and agglomeration area 2.33 is formed between the collecting parts 2.312 of two laterally adjacent condensing protrusions 2.31. After the fumes are guided and diverted by the two adjacent collecting parts 2.312, they gather and collide at the gathering and agglomeration area 2.33. The originally smaller oil droplets are thus agglomerated and agglomerated into larger oil droplets, making them easier to collect.
[0066] More preferably, the condensation protrusions 2.31 are provided in at least two rows. A condensation protrusion 2.31 is provided below the collection part 2.312 of the two laterally adjacent condensation protrusions 2.31 in the upper row. That is, the collection part 2.312 of the condensation protrusion 2.31 is located just below the aggregation area 2.33 between the two adjacent collection parts 2.312 in the upper row. After the oil droplets are aggregated and their size increases, they are captured by the collection part 2.312 in the lower row, thereby improving the collection effect of oil fume droplets.
[0067] More preferably, the condensation protrusions 2.31 are provided in three rows, with the lower row of condensation protrusions 2.31 positioned between the two adjacent condensation protrusions 2.31 in the nearest upper row.
[0068] In a preferred embodiment, the guide 2 is a one-piece molded part. The one-piece design offers advantages such as ease of processing and high overall strength. This design not only simplifies the manufacturing process but also improves the overall strength of the guide 2, ensuring its stability and reliability during long-term use. The one-piece design also reduces gaps between components, preventing the accumulation of oil fumes in these gaps and further improving the accuracy of detection.
[0069] In addition, the guide 2 can be made of a material that conducts heat quickly, such as aluminum alloy. During the flow and condensation of oil fumes, the heat is absorbed by the guide 2, which further ensures that the detection sensor 1 is not negatively affected by high temperature and its service life is guaranteed.
[0070] In a further embodiment, supports 7 and shielding side plates 8 connected to the supports are respectively provided on both sides of the fume analysis chamber a. The supports 7 and shielding side plates 8 on both sides prevent the fumes from escaping in two lateral directions, affecting the detection effect and the condensation and collection of the fumes. This design ensures that the fumes can be fully condensed in the fume analysis chamber a, avoiding the escape of the fumes and improving the accuracy of the detection. At the same time, the design of the shielding side plates 8 also reduces the indirect impact of the fumes on the detection sensor 1, further protecting the detection sensor 1.
[0071] In a further embodiment, an electronic control area b is arranged outside the shielding side panel 8 on one side of the fume analysis chamber a. A shielding cover 9 is installed in the electronic control area b facing the fume inlet. The shielding side panel 8 and the outer shielding cover 9 together form an electronic control area that avoids fume pollution, which can be used to house the circuit system, controllers, and other electronic components. This design effectively protects the electronic components within the electronic control area b, preventing contamination and damage from fumes, and improving the overall reliability and service life of the integrated stove. At the same time, the electronic control area b also facilitates the maintenance and repair of the circuit system.
[0072] In a further embodiment, the fan 3 is a cross-flow fan. The cross-flow fan is designed with high airflow and pressure, effectively drawing in cooking fumes and outputting them to the guide member 2. The fumes are primarily drawn in from the main smoke inlet 6, with a small portion flowing in from the fume inlet of the fume analysis chamber a inside the fume collection hood 4, located above the cooking area. The host computer component controls the fan speed of the integrated stove based on the signal from the detection sensor 1. By placing the fume analysis chamber a inside the fume collection hood 4, the integrated stove achieves fume detection, solving the problem of sensors being easily affected by high temperatures and oil stains in existing technologies, making the intelligent control of the integrated stove more accurate and stable.
[0073] In a further embodiment, please refer to the appendix. Figures 7-9 The condensing wall 2.3 is provided with multiple condensing protrusions 2.31, which divide the oil fume flow area into an internal flow area 2.31a and an external flow area 2.31b according to the flow direction of the oil fume.
[0074] The internal flow area 2.31a is sequentially equipped with a condensation inlet 2.311, a condensation channel 2.312, and a condensation outlet 2.313. The oil fumes enter through the condensation inlet 2.311, flow through the condensation channel 2.312, and exit through the condensation outlet 2.313. A condensation surface 2.314 is provided at the external flow area 2.31b to treat the oil fumes that do not enter the internal flow area 2.31a.
[0075] In this embodiment, the entire structure achieves forced convection in the oil fume flow path. For example, through the physical separation of the condensing protrusion 2.31, the oil fume is divided into two airflows, forming energy transfer and heat exchange, promoting the temperature drop of the oil fume and condensation into droplets. Specifically, the design of the condensing wall 2.3 and the condensing protrusion 2.31 can consider common materials such as metal or ceramic to enhance durability, but is not limited to these. The flow direction is based on the actual vertical arrangement of the installation to match the oil fume emission path of the integrated stove. This condensation mechanism achieves a highly efficient oil fume condensation effect.
[0076] As a preferred embodiment, the orientation and angle of the condensation outlet 2.313 are designed such that the oil fumes flowing out of the condensation outlet 2.313 at least partially merge with the oil fumes flowing over the condensation surface 2.314. This merging is achieved by adjusting the outlet direction of the condensation outlet 2.313, for example, by setting the condensation outlet 2.313 to be tilted outward or bent, to guide the oil fumes towards the condensation surface 2.314 area. In this embodiment, the merging point of the oil fumes can be located below the condensation surface 2.314. This merging promotes the convergence of oil fumes in the internal flow area 2.31a and the external flow area 2.31b, causing oil droplets to aggregate and grow larger during collisions, facilitating subsequent capture and removal, thereby promoting oil fume condensation. At the same time, this aggregation reduces noise and interference in humidity detection, such as avoiding misreading caused by small oil droplets adhering to the sensor surface, ensuring a more stable output signal of the humidity sensor, solving the inaccuracy problem of sensors caused by oil fume particles in the prior art, and providing reliable input.
[0077] As a preferred embodiment, a condensation channel 2.312 is provided between the condensation inlet 2.311 and the condensation outlet 2.313. This condensation channel 2.312 is configured to conform to the vertical flow direction of the oil fumes; for example, the channel shape is a straight line or a gentle slope design to avoid sharp bends or blockages, thereby reducing obstruction to the downward flow of oil fumes. The length and cross-section of the condensation channel 2.312 can be optimized for a smooth transition to accommodate changes in oil fume flow rate and ensure continuous airflow. The smooth vertical design of the condensation channel 2.312 minimizes flow resistance, maintains stable airflow, and thus reduces oil fume turbulence and pressure loss.
[0078] As a preferred embodiment, the condensation channel 2.312 between the condensation inlet 2.311 and the condensation outlet 2.313 is further designed to change the flow direction of the oil fumes as they approach or move away from the condensation wall 2.3. Specifically, this is achieved by providing an inclined surface or guide plate at the lower end of the condensation channel 2.312 to guide the oil fumes out of the condensation outlet 2.313 at an inclined angle, such as deflecting them outwards, to match the flow path of the external flow area 2.31b. This change in flow direction can be accomplished through channel bending or a baffle structure without introducing complex mechanics. This change in direction promotes the convergence of the oil fumes with the external flow area 2.31b, enhancing forced convection and condensation efficiency, for example, accelerating oil droplet formation. Simultaneously, the mixed oil fumes are more uniform, reducing localized oil concentration and providing a representative sample for the humidity sensor, thereby avoiding detection bias caused by environmental factors (such as temperature or humidity gradients).
[0079] As a preferred embodiment, the condensing surface 2.314 is positioned outside the condensing channel 2.312, for example, the condensing surface (2.314) is arranged parallel to the condensing channel 2.312, ensuring physical separation between the internal flow area 2.31a and the external flow area 2.31b. This separation facilitates independent processing of the oil fumes in the two areas, improving condensation efficiency.
[0080] As a preferred embodiment, the orientation of the condensation surface 2.314 is configured to allow the fumes to flow vertically downwards. For example, the condensation surface 2.314 is designed as a downwardly inclined or vertical surface to guide the fumes to fall naturally and ensure smooth downward movement. This vertical downward flow effectively carries the fumes gathered in the internal flow area 2.31a and the external flow area 2.31b downstream for further condensation or discharge.
[0081] As a preferred embodiment of the above, the condensing surface 2.314 is connected to the condensing wall 2.3 via connecting walls 2.315 on both sides, and the specific connection methods include welding, bolting, or integral molding.
[0082] This embodiment also provides an integrated cooktop, which is equipped with the host computer component described in any of the above embodiments. By setting up the host computer component, the integrated cooktop can achieve accurate detection of oil fumes, avoiding direct contact between oil fumes and the detection sensor, thus improving detection accuracy and sensor lifespan. The integrated cooktop can provide more accurate feedback based on the detection results, improving the stability and reliability of intelligent control. This design effectively solves problems such as oil stain adhesion, high-temperature damage, and detection method defects in the prior art, improving the overall performance and user experience of the integrated cooktop.
[0083] Please refer to the attached document again. Figure 10 This embodiment also provides a method for controlling the airflow of the integrated stove used in the above-mentioned cooking fume extraction, specifically including the following steps: First, start the integrated stove's range hood, the fan 3 for collecting the oil fumes to be detected, and the detection sensor 1. Next, the detection sensor 1 obtains the humidity parameter of the oil fumes and sends the humidity parameter signal to the controller. After receiving the humidity parameter signal, the controller compares it with a set humidity parameter range, interlocks the power level with the range in which the humidity parameter falls, thereby determining the current power level, and sends the power level signal to the controller. Subsequently, the controller interlocks the power level with the airflow level of the range hood according to the obtained power level signal, and controls the corresponding airflow level. Finally, the above steps are repeated every 30 seconds until cooking is finished. This embodiment determines the power level during cooking by using the oil fume humidity signal, and then obtains a suitable airflow level based on the power level, which can match the current cooking situation and obtain a suitable oil fume extraction power.
[0084] In a further embodiment, the relationship between humidity parameters and power and fan speed settings is described in detail. Specifically, the larger the set humidity range in which the detected humidity parameter falls, the higher the corresponding power and fan speed settings. By using the detected humidity parameter to positively correlate and interlock the fan speed and power settings, the airflow of the range hood can be dynamically adjusted according to the humidity of the cooking fumes, thereby more effectively absorbing the fumes and improving the fume extraction effect.
[0085] For example, the humidity parameter settings are divided into four ranges from high to low: a, β, γ, and θ. a is linked to the stir-fry power level, β to the high power level, γ to the low power level, and θ to the steaming power level. Similarly, the fan speed settings are divided into four levels from high to low: I, II, III, and IV. I is linked to the stir-fry power level, II to the high power level, III to the low power level, and IV to the steaming power level.
[0086] By using this zoning setting and its correspondence with the airflow level, the current heat level can be determined more accurately based on the humidity of the cooking fumes, thereby achieving more precise airflow control, improving the fume extraction effect, and ensuring that the range hood can provide the corresponding airflow under different cooking heat levels, thus more effectively absorbing cooking fumes and improving the fume extraction effect.
[0087] In a preferred embodiment, the cooktop is manually turned off when cooking is finished, and the range hood is delayed for 15-60 seconds before turning off. By delaying the range hood's shutdown time, residual cooking fumes can be absorbed, ensuring a clean kitchen environment. This design effectively avoids the problem of residual cooking fumes, improving the user experience. Simultaneously, the range hood retains a manual shut-off function to handle special situations, such as electrical control malfunctions, allowing the user to manually turn off the range hood and ensuring the equipment's safety and reliability. This design increases the equipment's flexibility and safety, enhancing the user experience.
[0088] In some embodiments, when the range hood is detected as being off, the fan 3 and the detection sensor 1 are shut down. The timing of shutting down the fan 3 and the detection sensor 1 is synchronized with the shutdown of the range hood, ensuring that all components work in coordination when the equipment is shut down, avoiding resource waste and equipment damage. This design improves the overall coordination and reliability of the equipment and extends its service life.
[0089] The above-described specific embodiments provide a control method that can dynamically adjust the fume extraction airflow level according to the humidity of oil fumes during cooking, thereby improving the fume extraction effect, optimizing the user experience, and increasing the safety and reliability of the equipment.
