[0002] With the improvement of living standards, people have higher and higher requirements for the cleanliness and hygiene of cooking devices. For example, in a steam oven, after cooking food multiple times, stains such as oil stains dripping from food will remain inside the cavity, which are difficult to clean, resulting in an unclean cooking environment.

[0003] Currently, in order to solve the problem of cleaning cooking devices, cooking devices are equipped with cleaning mechanisms to achieve self-cleaning functions. However, whether to clean still needs to be judged by the user himself. Since some cooking devices are embedded in the floor cabinets during installation, it is difficult for the user to observe the internal state of the cooking device, and it is difficult to accurately judge whether cleaning should be carried out and whether the cleaning result is clean, resulting in a low degree of automation in cleaning cooking devices. If stains are not cleaned in time for a long time, bacteria will breed, affecting user health and user experience.

[0063] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0064] During the cooking process, the identification and cleaning of oil stains are often a thorny problem. Currently, whether the cooking equipment needs to clean the cooking cavity requires the user to judge by themselves, resulting in poor convenience and low automation. Considering that Raman spectroscopy, as a supplement to infrared spectroscopy, is a powerful tool for studying molecular structures, it can identify substances and analyze their properties.

[0065] Therefore, the present application applies the Raman spectroscopy principle to cooking equipment, realizing the detection of oil stains in the cooking cavity, which helps the cooking equipment to automatically judge whether it needs to clean the cooking cavity, improving the automation degree of the cooking equipment and the convenience of use.

[0066] Refer to Figure 1 、 Figure 2 and Figure 3As shown in the figure, the present invention provides a cooking device, including: a cooking main body 10 and a spectral detection device 20. There is a cooking cavity 11 inside the cooking main body 10. The spectral detection device 20 is arranged on the cooking main body 10. Refer to Figure 4 , Figure 5 and Figure 6 As shown in the figure, the spectral detection device 20 includes a Raman probe 21, a laser generator 22, a detection unit 23 and a control unit 24. The Raman probe 21 is arranged on the laser transmission optical path emitted by the laser generator 22. The Raman probe 21 is used to emit the laser emitted by the laser generator 22 into the cooking cavity 11 and receive the reflected light from the object to be detected in the cooking cavity 11.

[0067] The detection unit 23 is electrically connected to the Raman probe 21. The detection unit 23 is used to detect the oil stain in the cooking cavity 11 according to the changes in the wavelength and frequency of the laser emitted by the Raman probe 21 and the received reflected light. The control unit 24 is electrically connected to the detection unit 23. The control unit 24 is configured to judge whether it is necessary to clean the cooking cavity 11 according to the detection result of the oil stain in the cooking cavity 11 by the detection unit 23.

[0068] For the cooking device provided by the present invention, by arranging the spectral detection device 20 on the cooking main body 10, the cooking device can realize the function of detecting oil stains, without the user having to judge by himself whether it is necessary to clean the cooking cavity 11, nor does the user have to judge by himself whether the cleaning result is clean, which improves the degree of automation of cleaning the cooking device and helps to improve the convenience of use.

[0069] In a possible implementation manner, refer to Figure 1 As shown in the figure, the cooking device provided by the present invention further includes a main control board 40, and the control unit 24 is electrically connected to the main control board 40.

[0070] In a possible implementation manner, refer to Figure 1 and Figure 4 As shown in the figure, the cooking device provided by the present invention further includes a cleaning device 30. The cleaning device 30 is arranged on the cooking main body 10, and the cleaning device 30 is electrically connected to the main control board 40.

[0071] The cleaning device 30 is used to clean the cooking cavity 11. The main control board 40 is used to control the cleaning device 30 to detect again by the spectral detection device 20 after the cleaning time reaches the preset time, and judge whether the cleaning result meets the standard, which ensures that the cleaning result of the cooking cavity 11 is qualified, helps to ensure the cleaning and sanitation effect of the cooking device, and improves the health of the cooked food.

[0072] In a possible implementation manner, refer to Figure 4 and Figure 10As shown in the figure, the cleaning device 30 includes a spray head 31, a motor 32, a water pipe 33, a pump 34, and a water tank 35. The spray head 31 can be arranged on the inner top wall of the cooking cavity 11. The water tank 35 is used to store water. The spray head 31 and the water tank 35 are connected through the water pipe 33. The pump 34 is connected to the water pipe 33. The pump 34 is used to make the water stored in the water tank 35 flow through the water pipe 33 to the spray head 31. The motor 32 is used to drive the spray head 31 to rotate. The side wall of the spray head 31 is provided with a water outlet 311. The periphery of the spray head 31 is provided with an impeller 312. The impeller 312 is used to break up the water flow sprayed out from the water outlet 311. The motor 32 and the driving spray head 31 are connected through a transmission mechanism 321. The transmission mechanism 321 can be, for example, a worm and worm gear mechanism, so that the water flow sprayed by the spray head 31 rotates, improving the cleaning effect.

[0073] In a possible implementation manner, the cleaning device 30 further includes a steam generator 36. The steam generator 36 is used to increase the water temperature used by the cleaning device 30, which is helpful for improving the cleaning effect.

[0074] In a possible implementation manner, referring to Figure 1 As shown in the figure, the main body 10 further includes a water collecting tray 39. The water collecting tray 39 is arranged at the bottom of the inner liner 13 and is used to accumulate the cleaned water flow. The water collecting tray 39 is connected with a water suction pipe 37. An electromagnetic valve 38 is arranged on the water suction pipe 37. The electromagnetic valve 38 is used to control the on-off of the water suction pipe 37.

[0075] A cooking device provided by the present invention can perform internal state detection of the cooking cavity 11 by the spectral detection device 20 after cooking to determine whether the oil stain needs to be cleaned. When cleaning is required, on the one hand, the reminder device arranged on the cooking main body 10 can be controlled by the main control board 40 to remind the user to clean. On the other hand, the cleaning device 30 can also be controlled by the main control board 40 to automatically realize cleaning, without relying on the user to detect the oil stain state inside the cooking cavity 11, and the degree of automation is high. The reminder device can be, for example, a buzzer, a horn, etc., and can also be a warning light.

[0076] In addition, the cleaning result can be detected again by the spectral detection device 20 to judge whether the oil stain cleaning is qualified. After the judgment result is completely qualified, the reminder device can be controlled by the main control board 40 to remind the user to end the cleaning, or the cleaning device 30 can be controlled by the main control board 40 to end the cleaning work.

[0077] In a possible implementation manner, referring to Figure 5 and Figure 6As shown, the spectral detection device 20 further includes a temperature detection unit 25 and a heat dissipation unit 26. Both the temperature detection unit 25 and the heat dissipation unit 26 are electrically connected to the control unit 24. The temperature detection unit 25 is used to detect the temperature inside the spectral detection device 20, and the heat dissipation unit 26 is used to dissipate heat from the spectral detection device 20 when the detected temperature by the temperature detection unit 25 is higher than a preset temperature.

[0078] To prevent the high-temperature environment from affecting the function of the spectral detection device 20, the temperature detection unit 25 continuously detects the temperature inside the spectral detection device 20. When the temperature detected by the temperature detection unit 25 is higher than the preset temperature, the heat dissipation unit 26 starts to work to dissipate heat from the spectral detection device 20 and prevent the spectral detection device 20 from being damaged due to overheating.

[0079] In a possible implementation manner, the heat dissipation unit 26 can be a fan.

[0080] In a possible implementation manner, the number of the temperature detection units 25 can be one, or can also be two or more to improve the accuracy of temperature detection. The temperature detection unit 25 can be a temperature sensor, for example, it can be a resistive temperature sensor or an infrared temperature sensor. Its structure and working principle are both prior arts and will not be elaborated here.

[0081] In a possible implementation manner, the spectral detection device 20 further includes a data transmission unit 28. The data transmission unit 28 is used to convert the temperature information detected by the temperature detection unit 25 into a digital signal and transmit it to the detection unit 23. Among them, the data transmission unit 28 can be an existing A / D converter. Its structure and working principle are prior arts and will not be elaborated here.

[0082] The spectral detection device 20 uses the Raman spectroscopy principle to detect and analyze the object to be measured. When light hits the object to be measured, that is, the sample, the sample molecules will cause the incident light to scatter. Most of the scattered light has the same frequency, which is Rayleigh scattering, and some of the scattered light has a changed frequency, which is Raman scattering. The Raman shift is obtained based on the frequency difference between the scattered light and the incident light.

[0083] Reference Figure 11 As shown, the explanation of Raman scattering is that the incident photon undergoes inelastic scattering with the molecule. The molecule absorbs a photon with a frequency of υ 0 and emits a photon with υ 0 -υ 1 Meanwhile, the molecule transitions from a low energy state to a high energy state, Stokes line; the molecule releases a photon with a frequency of υ 0 and emits a photon with υ 0 +υ 1Photons, while the molecule transitions from a high-energy state to a low-energy state for the anti-Stokes line. When the transition of the molecular energy level only involves the rotational energy level, the emitted is a small Raman spectrum; when it involves the vibrational-rotational energy level, the emitted is a large Raman spectrum.

[0084] The Raman effect originates from molecular vibrations and lattice vibrations and rotations. Therefore, the molecular vibrational energy levels, lattice vibrational energy levels, and rotational energy level structures can be obtained from the Raman spectrum. Since the vibration modes of different types of atomic groups are unique, scattered light with a specific difference from the incident light frequency can be generated, and its spectrum is called the "fingerprint spectrum", based on which the types of molecules that make up the substance can be identified.

[0085] Reference Figure 1 、 Figure 5 and Figure 6 As shown in

[0086] the working principle of the spectral detection device 20: When it is necessary to detect the inside of the cooking cavity 11, the laser generator 22 is started and emits a beam of laser, which reaches the Raman probe 21 through transmission. The Raman probe 21 emits the laser into the cooking cavity 11 for detecting the object to be measured. The laser interacts with the object to be measured inside the cooking cavity 11. Part of the laser is absorbed by the object to be measured, while most of the laser is reflected. The reflected laser is captured by the Raman probe 21 and preliminarily processed by the Raman probe 21. The processed Raman scattering signal is transmitted back to the detection unit 23 of the spectral detection device 20 through the optical fiber. The detection unit 23 further analyzes the Raman scattering signal to determine the type and concentration of the object to be measured. The detection unit 23 sends the detection result to the control unit 24, and the control unit 24 judges whether it is necessary to clean the cooking cavity 11.

[0087] The spectral detection device 20 can perform non-destructive detection without pretreatment, and has the advantages of no pollution, simple and convenient use, fast speed, and suitability for on-site detection.

[0088] In a possible implementation manner, reference Figure 7 and Figure 8As shown in the figure, the Raman probe 21 includes a probe body 211 and a housing 212. The housing 212 has an accommodation cavity 2122 inside. The probe body 211 is arranged in the accommodation cavity 2122. One end of the housing 212 facing the cooking cavity 11 has an opening 2121. The housing 212 includes a protective cover plate 2124 that blocks the opening 2121.

[0089] The protective cover plate 2124 can play a role in heat insulation, effectively preventing the heat inside the cooking cavity 11 from directly invading the inside of the housing 212 and affecting the probe body 211, so that the normal operation of the Raman probe 21 is not disturbed by the heat inside the cooking cavity 11, thereby ensuring the detection effect of the spectral detection device 20.

[0090] In a possible implementation manner, the probe body 211 includes: a probe housing 2111, a dichroic mirror 2112, a filter 2113, and an optical lens 2114. An inner cavity 2115 is formed inside the probe housing 2111. At least one end of the probe housing 2111 is provided with an optical lens 2114. The filter 2113 is arranged in the inner cavity 2115. The dichroic mirror 2112 is located between the optical lens 2114 and the filter 2113. The dichroic mirror 2112 is used to separate the colors of the reflected light reflected by the object to be measured and reproduce the colors more accurately for the next detection work, increasing the detection accuracy.

[0091] In a possible implementation manner, the filter 2113 is a narrow-band pass filter. The narrow-band filter is formed by stacking multiple thin films, and the refractive index and thickness of each layer of film are optimized. Through the thickness and refractive index between the thin film layers, the phase difference of the reflected light can be adjusted to achieve interference of wavelengths that do not need to be detected. When the reflected light reflected by the object to be measured further passes through the filter 2113, most of the useless light will be reflected or absorbed, and only the light with wavelengths within a set specific range will be transmitted for subsequent detection work.

[0092] In order to further achieve full-range detection inside the cooking cavity 11, the optical lens 2114 can be a convex lens. Compared with a traditional plane mirror, the convex lens has a wider detectable range inside the cooking cavity 11, can monitor a larger area, is more suitable for large-area detection inside the cooking cavity 11, and helps to achieve a larger field of view.

[0093] In a possible implementation manner, optical lenses 2114 are provided at both opposite ends of the probe housing 2111, and dichroic mirrors 2112 are arranged between each optical lens 2114 and the filter 2113, which helps to achieve a larger field of view.

[0094] In a possible implementation, the position of the optical lens 2114 at at least one end of the probe housing 2111 can be adjusted. For example, the optical lens 2114 can be extended in the direction extending outside the probe housing 2111, so that the distance between the adjusted optical lens 2114 and the dichroic mirror 2112 is changed to achieve zooming and improve the detection effect of oil stains.

[0095] In a possible implementation, refer to Figure 7 and Figure 8 As shown, an installation bracket 2116 is further provided on the inner wall surface of the probe housing 2111. The filter 2113 is fixed to the installation bracket 2116, and the installation bracket 2116 abuts against the dichroic mirror 2112 and the optical lens 2114.

[0096] In a possible implementation, the installation bracket 2116 includes an installation plate 2118 and an installation card seat 2119. The installation plate 2118 and the installation card seat 2119 cooperate with each other to install the dichroic mirror 2112, the filter 2113, and the optical lens 2114, and at the same time define the distances among the dichroic mirror 2112, the filter 2113, and the optical lens 2114, so that the Raman probe 21 achieves a better detection effect.

[0097] In a possible implementation, one side of the installation bracket 2116 facing away from the probe housing 2111 has a limiting step 21161. One side of the dichroic mirror 2112 facing the filter 2113 abuts against the limiting step 21161, and one side of the optical lens 2114 facing the dichroic mirror 2112 abuts against the top or bottom end of the installation bracket 2116.

[0098] In a possible implementation, a limiting member 2117 is further provided in the probe housing 2111. The limiting member 2117 abuts between the filter 2113 and the inner wall surface of the inner cavity 2115.

[0099] In a possible implementation, the limiting member 2117 can be a limiting block. The limiting member 2117 is made of a material that can insulate heat and has shock-absorbing performance. The limiting member 2117 is arranged in the empty space in the inner cavity 2115. The limiting member 2117 plays a role in protecting the probe body 211 and limiting the filter 2113.

[0100] Refer to Figure 9As shown, the cooking main body 10 includes a main frame 12 and an inner pot 13. There is a spaced space 15 between the main frame 12 and the inner pot 13. The inner pot 13 forms the inner wall surface of the cooking cavity 11. The Raman probe 21 is arranged on the main frame 12. To ensure comprehensive detection of the cooking cavity 11, the installation position of the Raman probe 21 on the main frame 12 can be flexibly selected. For example, the Raman probe 21 can be located on the top surface of the main frame 12, or on the side surface of the main frame 12, or on the back surface of the main frame 12, so as to be installed at a position where the inside of the cooking cavity 11 can be comprehensively detected.

[0101] In a possible implementation manner, an installation seat 141 is arranged on the main frame 12. A positioning hole 1411 is formed inside the installation seat 141.

For example, the protective cover plate 2124 can be entirely made of a transparent glass plate, or a partial position is made of a transparent glass plate.

[0112] The cable 27 is connected to one end of the Raman probe 21 relative to the protective cover plate 2124. The laser emitted by the laser generator 22 is transmitted to the Raman probe 21 through the cable 27.

[0113] In a possible implementation manner, a limit cover 271 is disposed at one end of the cable 27 connected to the Raman probe 21. A limit seat 2123 is disposed at the top end of the housing 212.

[0115] With such a structure, by installing the Raman probe 21 on the mounting seat 141 of the main frame 12, the adverse effects of the heat in the cooking cavity 11 on the Raman probe 21 can be reduced. In addition, by setting up the optical path component 50, the transmission of optical signals between the Raman probe 21 and the cooking cavity 11 is realized, eliminating the adverse effects of the gap space 15 between the main frame 12 and the inner liner 13 on the detection effect of the Raman probe 21.

[0119] Of course, in other possible implementation manners, the Raman probe 21 can also be arranged to be lifted and lowered in the positioning hole 1411.

[0127] Reference Figure 12 As shown, the present invention also provides a cleaning control method for a cooking device, which is applied to the above cooking device. The method includes:

[0128] S10. Start the spectral detection device to obtain the oil stain parameters in the cooking cavity of the cooking device;

[0129] S20. Match the corresponding cleaning mode according to the oil stain parameters in the cooking cavity;

[0130] S30. If the oil stain parameters in the cooking cavity are greater than or equal to the preset threshold, clean the cooking cavity in the corresponding cleaning mode.

[0131] A cleaning control method for a cooking device provided by the present invention combines spectral detection technology with the selection of cleaning modes, enabling the cooking device to intelligently judge oil stains and select an appropriate cleaning mode. This not only improves the cleaning efficiency of the cooking device but also extends its service life and enhances the hygiene of use.

[0132] Among them, in step S10, the spectral detection device is started, and the spectral detection device can identify and quantify the presence and degree of oil stains by analyzing the absorption, reflection, or scattering characteristics of light.

[0133] The purpose of step S20 is to select the most suitable cleaning solution according to different oil stains to optimize the cleaning effect. Different cleaning modes may include different cleaning times, temperatures, cleaning agent concentrations, etc. to effectively remove oil stains.

[0134] In step S30, the cleaning process is started only when the oil stains reach a certain degree, thus saving resources and time. The preset threshold can be adjusted according to the usage situation and cleaning requirements of the device.

[0135] In a possible implementation manner, referring to Figure 13 as shown, the cleaning control method of the cooking device further includes:

[0136] S40. Real-time detect the temperature inside the spectral detection device;

[0137] S41. If the detected temperature inside the spectral detection device is greater than or equal to the preset temperature, start the heat dissipation unit for heat dissipation;

[0138] S42. If the detected temperature inside the spectral detection device is less than the preset temperature, turn off the heat dissipation unit.

[0139] Among them, in step S41, starting the heat dissipation unit 26 for heat dissipation helps prevent the spectral detection device 20 from overheating, protects the normal operation of the spectral detection device 20, and extends its service life. In step S42, when the detected temperature inside the spectral detection device 20 is less than the preset temperature, the heat dissipation unit 26 is turned off to save energy and reduce unnecessary noise. This intelligent control ensures that the heat dissipation unit 26 operates only when needed, improving energy efficiency.

[0140] In a possible implementation manner, referring to Figure 14 as shown, start the spectral detection device 20 to obtain the oil stain parameters in the cooking cavity 11 of the cooking device, including:

[0141] S11. Start the Raman probe and the laser generator so that the laser generator emits laser light, and the Raman probe emits the laser light emitted by the laser generator into the cooking cavity and receives the reflected light from the object to be detected in the cooking cavity;

[0142] S12. The startup detection unit. The detection unit detects the oil stain parameters in the cooking cavity according to the changes in the wavelength and frequency of the laser emitted by the Raman probe and the received reflected light.

[0143] In this application, by utilizing the high sensitivity and specificity of Raman spectroscopy, it is possible to detect the oil stains in the cooking cavity 11 of the cooking device without contacting the food ingredients. The application of this technology can improve the accuracy and efficiency of detection and provide reliable data support for the subsequent cleaning process.

[0144] The Raman probe 21 and the laser generator 22 are the core components for oil stain detection. The laser generator 22 emits a laser with a specific wavelength, and the Raman probe 21 guides the laser to the target area in the cooking cavity 11. When the laser irradiates the object to be detected (such as oil stain) in the cooking cavity 11, Raman scattering occurs. This scattered light contains the molecular characteristic information of the substance, thereby realizing the detection of the oil stain parameters in the cooking cavity 11.

[0145] In a possible implementation manner, obtaining the oil stain parameters in the cooking cavity 11 of the cooking device includes: obtaining the type of the oil stain and the concentration of the oil stain.

[0146] In a possible implementation manner, as shown in Figure 15 the cleaning control method of the cooking device further includes:

[0147] S50. After each cleaning of the cooking cavity is completed, re-detect the oil stain parameters in the cooking cavity of the cooking device;

[0148] S60. If the oil stain parameters in the cooking cavity are greater than or equal to the preset threshold, re-clean the cooking cavity;

[0149] S70. If the oil stain parameters in the cooking cavity are less than the preset threshold, end the cleaning of the cooking cavity.

[0150] Through these steps, the cleaning process of the cooking device becomes more intelligent and automated, ensuring that each cleaning can achieve the expected effect. This method not only improves the cleanliness of the device but also optimizes the use of resources and avoids unnecessary cleaning operations.

[0151] By re-detecting the oil stain parameters in the cooking cavity 11 of the cooking device after each cleaning of the cooking cavity 11 in step S50, the cleaning effect can be verified and it can be determined whether further cleaning operations are required. This feedback mechanism helps to ensure that the device meets the required cleaning standards after each cleaning.

[0152] Through step S60, if the oil stain parameter in the cooking cavity 11 is greater than or equal to the preset threshold, the cooking cavity 11 is cleaned again to ensure that even if the oil stains cannot be completely removed during the first cleaning, the device can still reach an ideal cleaning state through repeated cleaning.

[0153] Through step S70, if the oil stain parameter in the cooking cavity 11 is less than the preset threshold, the cleaning of the cooking cavity 11 is ended. This indicates that the cooking cavity 11 has reached the expected cleaning standard and can be used safely.

[0154] Reference Figure 4 and Figure 5 As shown, when the user puts the food ingredients into the cooking cavity 11, the spectral detection device 20 will be immediately activated to automatically conduct a preliminary analysis on the object placed in the cooking cavity 11, identify the type of food ingredients, and provide preliminary information about the oil component of the food. According to the cooking menu selected by the user, the cooking device will intelligently set a suitable detection temperature range to avoid the influence of temperature fluctuations on the detection results of the spectral detection device 20 and ensure the accuracy of the obtained food oil information. Considering that different types and concentrations of oils require different cleaning solutions, a multi-temperature test strategy is adopted to conduct a detailed analysis of the oil stains to determine the types and concentrations of the main oils.

[0155] By detecting and analyzing the types and concentrations of the oils, the pertinence and effectiveness of the cleaning process can be ensured, the cleaning efficiency can be significantly improved, and ultimately a cleaner and more hygienic cooking environment can be provided for the user. To achieve this goal, it is necessary to ensure the accuracy of the data on the types and concentrations of the oils in the detection cavity to improve the user experience effect.

[0156] Currently, Raman spectroscopy detection technology is applied in various industries. When Raman spectroscopy technology is used for detection in an all-in-one machine, it is not only necessary to judge the types of oil stains in the cooking cavity 11, but also necessary to obtain the oil stain concentrations before and after the cleaning of the cooking cavity 11 to judge whether the cleaning work of the cooking cavity 11 is in place. For this purpose, a detection substance concentration model needs to be added for accuracy calibration.

[0157] To improve the accuracy of the identification of cooking ingredients, first, a mixed liquid of 25% concentration lard and water is taken as a sample liquid for detection and calibration to obtain the normalized detection spectrum of the oil-containing sample liquid. And this method is applied to detect other types of oils to establish a database, enabling the Raman spectrometer to effectively identify the state and type of the oil stains in the cavity, and controlling the cleaning device 30 to match the corresponding cleaning mode according to this by the control unit 24.

[0158] After the spectroscopic detection device 20 observed the prepared sample solution of the cooked food, it was found that when the sample solution contained 25% lard and the magnification was 40X, as the temperature in the cooking chamber 11 increased, the degree of dispersion of the oil droplets in the sample solution gradually increased. When the temperature in the cooking chamber 11 was 65°C, the distribution of the oil droplets in the sample solution was better, and the ratio of the oil droplets to the field of view reached the maximum value at this time, indicating that the oil droplets formed by oil stains and the like existed in the form of large oil droplets in the sample solution.

[0159] An identity relationship established based on the principle that the total volume of the oil droplets in the sample solution remains unchanged after making the film:

[0160]

[0161] Among them, r is the radius of the oil stain beads in the field of view after making the film; h is the thickness of the oil stain beads after making the film; R is the radius of the oil stain beads in the sample solution.

[0162] After multiple calculations, the weight of two drops of oil-containing sample solution was calculated to be 0.037 g, and the density of the prepared sample solution was measured. From the formula: ρ = m / v

[0163] In the formula: ρ is the density of the oil stain solution; m is the weight of two drops of oil-containing sample solution; v is the volume of the sample solution. The volume of two drops of oil-containing sample solution was calculated to be 0.02 cm 3 . The thickness under the cover slip of two drops of oil-containing sample solution is 50 μm. The diameter of the oil droplets can be obtained from the microscopic photo, and the oil droplet diameter is substituted into the formula

[0164] πr 2 h = 4πR 3 / 3

[0165] Thus, the true volume of the oil droplets can be deduced from the microscopic photo.

[0166] Through the Raman spectroscopic analysis of this volume of sample, the linear relationship between the oil stain concentration in the sample solution and the Raman spectrum at 65°C was obtained:

[0167] y = 145.8x + 1319

[0168] Among them, x is the oil stain concentration in the sample solution, and y is the Raman peak value.

[0169] In order to eliminate the influence of environmental and other factors on the Raman spectrum of the substance to be measured in the cavity, the measured Raman spectrum of the oil-containing sample solution was normalized, and the normalized detection spectrum X of the oil-containing sample solution was deduced as:

[0170] Among them

[0171]

[0172] The relative Raman intensity coefficient K of the background sample liquid, where a and b are spectral synthesis coefficients. The Raman peak of 25% lard at 1519 cm-1 at 65°C was measured to be 1595.5, and the error from the spectral peak obtained by normalization was 0.5%. According to this method, the Raman peaks of 25% lard at 1519 cm-1 at 15°C, 25°C, 35°C, 45°C, 55°C, 75°C, and 95°C are as shown in Table 1 below.

[0173] Table 1

[0174]

[0175] Since some cooking devices have diverse cooking modes, the temperature inside the cooking cavity 11 will also change accordingly. And during the actual detection process after cooking, as cooking ends, the temperature inside the cooking cavity 11 drops linearly. To enhance the accuracy of the test data of the spectral detection device 20, the temperature factor is also considered in the spectrum of the substance to be measured, and thus a relationship between temperature and the normalized spectrum is established to accurately detect the Raman spectrum of the substance to be measured in the cavity at different temperatures:

[0176] X T = X ± 1.6T

[0177] where T is the temperature.

[0178] After cooking ends and the food inside the cooking cavity 11 is taken out, the temperature sensor inside the cooking cavity 11 detects the temperature inside the cooking cavity 11, and the obtained temperature detection data is promptly fed back to the detection unit 23 of the spectral detection device 20. The detection unit 23 detects the type and concentration of the grease inside the cooking cavity 11 at different temperatures according to the algorithm.

[0179] In this process, the detection spectrum X of 25% lard in the sample liquid at 15°C to 95°C is obtained. By the same method, the detection spectra X1, X2, X3... of lard concentrations of 40%, 60%, 75%, 90%, and 100% at 15°C to 95°C can be obtained.

[0180] Set the oil stain concentration of 25% that the cooking device needs to clean as A, and the corresponding detection spectrum as X. When the spectral detection is X, it means that the oil stain has reached the cleaning value set by the system, and the cleaning mode of the cooking device can be started. At the same time, the number of cleaning cycles is matched according to the different spectra corresponding to different concentrations.

[0181] First, calibrate the detection spectra of lard, beef tallow, vegetable oil, and mixed oil at a concentration of 25% - 100% from 15°C to 95°C. The corresponding spectra are X pig1, X pig2, and X pig3... X cow1, X cow2, and X cow3... Let the 25% oil stain concentration be the starting cleaning definition concentration. The spectral detection device 20 measures spectra Xx1, Xx2, and Xx3... (x represents different oil types), indicating that the oil stain has reached the system-set cleaning value. After the cooking device finishes cooking, the spectral detection device 20 detects the interior of the cooking cavity 11 to determine whether cleaning is required. If the determination is yes, the cleaning mode of the cooking device can be activated.

[0182] At the same time, according to the different appropriate water temperatures required for different oils during cleaning, set the working temperature of the steam generator 36 so that the water temperature for cleaning reaches a more appropriate flushing temperature, improving the cleaning effect. At the same time, set the initial cleaning cycle to 10 minutes. After the cycle ends, the spectral detection device 20 continues to re-determine the oil stain in the cooking cavity 11. If it is determined that cleaning is required, the control unit 24 controls the cleaning device 30 to perform the cleaning work. If it is determined that cleaning is not required, a reminder sound can be emitted through the reminder device to remind the user that the cleaning work is over.
