Description

Technical Field

[0001] This invention belongs to the field of kitchen appliance technology, specifically relating to an integrated stove fume control system and control method. Background Technology

[0002] Integrated cooktops are a common household appliance in the kitchen appliance market. They mainly consist of a combination cabinet, a gas stove mounted on the countertop, and a range hood that collects and exhausts cooking fumes and smoke. The range hood includes a fume hood for collecting fumes and a fan located inside the cabinet and connected to the fume hood, which expels the fumes and smoke outdoors. Compared to traditional separate kitchen appliance designs, integrated cooktops offer the following advantages: a more compact structure, higher space utilization, effectively saving kitchen space; integration of cooking, fume extraction, and storage functions, providing comprehensive functionality and greater convenience; and a cleaner, more aesthetically pleasing design, enhancing the overall kitchen aesthetic.

[0003] To minimize the space occupied by the fume hood, the fume hood in integrated cooktops is smaller than that of traditional fixed range hoods. To ensure that the small fume hood's suction inlet aligns well with the burner on the gas stove for precise and efficient fume extraction, integrated cooktops often include a drive mechanism to adjust the fume hood's position. Examples include the integrated cooktop designs disclosed in utility model patent CN215295002U and invention patent CN108302579A. Both of these patents feature a protruding air box at the front of the cooktop, with the fume hood mounted on top of the air box via a rotating mechanism. When using the cooktop, the position of the fume hood can be adjusted by driving the rotating mechanism, bringing it closer to the cooktop for precise fume extraction. After cooking, the user can also manually rotate the mechanism to reset the fume hood, improving kitchen cleanliness. However, the fume hood control of this type of integrated stove relies solely on user adjustment. In reality, manual adjustment makes it difficult to precisely adjust the fume hood to the optimal position for fume extraction, especially when using cookware of different sizes. Simply mechanically adjusting the fume hood to a fixed position makes it difficult to guarantee the integrated stove's fume extraction effectiveness. Summary of the Invention

[0004] The primary objective of this invention is to provide an integrated stove fume control system with high accuracy in fume extraction and excellent fume purification effect, which is achieved through the following technical solution:

[0005] An integrated stove fume control system, characterized in that it comprises: a data acquisition module, a data processing module, and a fume purification module connected in sequence;

[0006] The data acquisition module is used to collect the concentration value of oil fumes near the stove.

[0007] The data processing module is used to analyze the oil fume concentration data and obtain the processing results;

[0008] The smoke purification module includes an execution submodule for smoke purification treatment and a control submodule for controlling the execution submodule; the control submodule includes an angle control unit for adjusting the rotation angle of the smoke collection hood according to the processing result; the execution submodule includes a drive unit for driving the smoke collection hood to rotate according to the instructions of the angle control unit.

[0009] As a further preferred embodiment, the integrated stove includes a support pipe that is connected to one end of the smoke collection hood and is used to install the smoke collection hood on the integrated stove countertop.

[0010] As a further preferred embodiment, the drive unit is used to drive the smoke hood to rotate around the central axis of the supporting pipe, and the angle of rotation is less than 90 degrees.

[0011] As a further preferred embodiment, the data acquisition module includes a first acquisition unit disposed at the end of the fume hood near the stove, and a second acquisition unit disposed in the direction of fume escape from the fume hood.

[0012] In practice, to increase the surface area for collecting fumes in the fume hood, the lower surface of the fume hood with the smoke guide opening is often inclined. Taking this as an example, the end of the fume hood near the stove refers to the end of the lower surface of the fume hood closest to the stove; correspondingly, the direction of fume escape is the end of the lower surface of the fume hood furthest from the stove. Of course, when the fume hood has a front surface on the user side that connects to the side of the lower surface furthest from the stove, the second collection unit can also be located on the front surface.

[0013] As a further preferred option, the first and second acquisition units employ smoke sensors.

[0014] As a further preferred embodiment, the data processing module includes a first calculation unit for analyzing the oil fume concentration values ​​collected by the first acquisition unit, and a second calculation unit for analyzing the oil fume concentration values ​​collected by the second acquisition unit.

[0015] As a further preferred embodiment, the control submodule further includes a fan control unit for adjusting the fan's operating mode according to the processing result; the execution submodule further includes a fan unit for adjusting the fan's operating mode according to the instructions of the fan control unit.

[0016] The second objective of this invention is to provide a control method based on the aforementioned integrated stove fume control system, which offers high accuracy in fume extraction, excellent fume purification, and energy efficiency. This is achieved through the following technical solution:

[0017] The control method includes the following steps: setting the starting oil fume concentration value of the first acquisition unit to Y1 and the starting oil fume concentration value of the second acquisition unit to Y2; the first acquisition unit detects the oil fume concentration to obtain an oil fume concentration value Y3; when the oil fume concentration value Y3 is greater than Y1, the second acquisition unit detects the oil fume concentration to obtain an oil fume concentration value Y4; when the oil fume concentration value Y4 is greater than Y2, the fume hood rotates from its initial position to above the stovetop. The initial position refers to the position of the fume hood at the end of the integrated stove furthest from the user.

[0018] The aforementioned starting fume concentration value is a system preset value. Its purpose is to provide a numerical reference condition for the rotation start of the fume hood—that is, the fume hood will only rotate above the stovetop when the fume concentration values ​​collected by the first and second collection units on the fume hood both reach the corresponding preset starting fume concentration value. Because the first collection unit is closer to the stovetop, it can come into contact with the fume first compared to the second collection unit. This setting allows for sensitive fume detection while reducing energy consumption when the first and second collection units are activated simultaneously.

[0019] As a further preferred embodiment, after the fume hood rotates to above the stove, the control method further includes the following steps: the second acquisition unit detects the oil fume concentration above the stove and obtains the oil fume concentration value Y5; when the oil fume concentration value Y5 is greater than Y2, the fan operates in a high-power mode; when the oil fume concentration value Y5 is less than Y2, the fan operates in a low-power mode.

[0020] If the oil fume concentration value Y5 is greater than Y2, it indicates that the amount of oil fume is relatively large. In this case, adjusting the fan to high-power operation mode will efficiently absorb the oil fume, resulting in higher purification efficiency. If the oil fume concentration value Y5 is less than Y2, it indicates that the amount of oil fume is relatively small. Adjusting the fan to low-power operation mode can save energy while ensuring the oil fume purification effect.

[0021] As a further preferred embodiment, the control method further includes the following steps: the first acquisition unit detects the oil fume concentration value to obtain the oil fume concentration value Y7; the target oil fume concentration value of the first acquisition unit is set to Y6; when the smoke concentration value Y7 is less than Y6, the fan stops working and the smoke collection hood returns to its initial position.

[0022] By setting a target oil fume concentration value and comparing it with the oil fume concentration value detected by the first collection unit, the smoke collection stove can automatically shut off after the oil fume extraction is completed. This will avoid unnecessary energy consumption caused by users forgetting to turn off the fan, thus making the equipment more convenient and safer to use.

[0023] As a further preferred embodiment, after the fume hood rotates to above the stove, the following steps are also included: the second acquisition unit detects the oil fume concentration above the stove and obtains an oil fume concentration value Y5; when the oil fume concentration value Y5 is less than Y2, the first acquisition unit detects the oil fume concentration value and obtains an oil fume concentration value Y7; the target oil fume concentration value of the first acquisition unit is set to Y6; when the oil fume concentration value Y7 is less than Y6, the fan stops working and the fume hood returns to its initial position.

[0024] The aforementioned target fume concentration value is a system preset value. Its purpose is to provide a numerical reference condition for the return of the fume hood to its original position—that is, the fume hood will only be driven to rotate back to its initial position when the fume concentration value collected by the first collection unit on the fume hood reaches the target fume concentration value. Therefore, the target fume concentration value is usually lower than the starting fume concentration value.

[0025] Furthermore, it should be noted that the smoke hood of this application can be automatically triggered by the system to rotate and reset when Y7 is less than Y6, or it can be rotated and reset by the user manually turning off the fan.

[0026] A third object of the present invention is to provide a processor for running a program that performs the control method described in any of the preceding claims.

[0027] A fourth object of the present invention is to provide a storage medium storing a program that executes the control method described in any one of the preceding claims.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The integrated stove fume control system of this application, through the design of a data acquisition module, a data processing module, and a matching smoke purification module, can realize the automatic rotation of the fume hood and the adjustment of the wind speed. Therefore, no manual control operation is required, making the operation of the fume hood in the integrated stove more intelligent and extremely convenient to use.

[0030] This application monitors and analyzes the oil fume concentration at different locations within the fume hood, and adjusts the position of the fume hood and the airflow of the fan based on the analysis results. On the one hand, it can reasonably adsorb oil fumes based on objective oil fume concentration, thus achieving higher precision in oil fume purification. On the other hand, it can also prevent unnecessary energy consumption caused by users forgetting to turn off the fan, thus improving the convenience and safety of the equipment.

[0031] Based on the integrated stove fume control system, this application, through the design of special steps in the control method, makes the integrated stove's operation more environmentally friendly. Furthermore, other beneficial effects of this application will be specifically elaborated in the embodiments. Attached Figure Description

[0040] The present application will be further described below with reference to specific embodiments. Those skilled in the art will be able to implement the present application based on these descriptions. Furthermore, the embodiments of the present application described below are generally only a part of the embodiments of the present application, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort should fall within the scope of protection of the present application.

[0041] Example 1

[0042] Please see Figures 1-2 This embodiment discloses an integrated stove fume control system. Specifically, the integrated stove includes a body 1, two cooktops 2 evenly distributed on the body, and two fume collection devices disposed on both sides of the end of the body away from the user. The fume collection device includes a fume hood 3 for absorbing fumes above the cooktops 2, and a support pipe 4 that is connected to one end of the fume hood 3 and used to fix the fume hood 3 to the upper surface of the body 1.

[0043] The integrated stove fume control system includes a data acquisition module, a data processing module, and a fume purification module connected in sequence.

[0044] The data acquisition module is used to collect the concentration value of oil fumes near the stove; specifically, it includes a first acquisition unit set at the end of the fume hood near the stove, and a second acquisition unit set in the direction of oil fume escape from the fume hood; in this embodiment, the first acquisition unit and the second acquisition unit are smoke sensors.

[0045] The data processing module is used to analyze the oil fume concentration data and obtain the processing results; specifically, it includes a first calculation unit for analyzing the oil fume concentration values ​​collected by the first acquisition unit, and a second calculation unit for analyzing the oil fume concentration values ​​collected by the second acquisition unit.

[0046] The smoke purification module includes an execution submodule for smoke purification treatment and a control submodule for controlling the execution submodule. The control submodule includes an angle control unit for adjusting the rotation angle of the smoke collection hood according to the processing result. The execution submodule includes a drive unit for driving the smoke collection hood to rotate according to the instructions of the angle control unit. The drive unit drives the smoke collection hood to rotate around the central axis of the supporting pipe, and the rotatable angle of the smoke collection hood is less than 90 degrees.

[0047] Example 2

[0048] Please see Figures 3-4 This embodiment discloses a control method for the integrated stove fume control system described in Embodiment 1, including the following steps:

[0049] S1. Set the starting oil fume concentration value of the first collection unit to Y1, and the starting oil fume concentration value of the second collection unit to Y2;

[0050] S2. The first collection unit detects the oil fume concentration and obtains the oil fume concentration value Y3. Specifically, since the first collection unit is closer to the stove, it can come into contact with the oil fume first compared to the second collection unit. This setting can reduce the energy consumption when the first and second collection units are turned on at the same time.

[0051] S3. The first calculation unit determines whether the oil fume concentration value Y3 is greater than Y1. If so, step S4 is executed; otherwise, steps S2 and S3 are repeated.

[0052] S4. The second acquisition unit detects the oil fume concentration and obtains the oil fume concentration value Y4.

[0053] S5. The second calculation unit determines whether the oil fume concentration value Y4 is greater than Y2. If so, it runs step S6; otherwise, it repeats steps S4 and S5.

[0054] S6. The angle control unit commands the drive unit to rotate the fume hood, causing it to rotate 45 degrees from its initial position around the central axis of the support pipe to above the stovetop, thus absorbing the cooking fumes. Specifically, when the fume concentration detected by the first and second collection units both reach their respective activation fume concentration values, it indicates that the fume concentration is high. By commanding the drive unit to rotate the fume hood at this point, energy can be saved while achieving precise fume absorption, thus making the fume removal more efficient.

[0055] S7. The second acquisition unit detects the oil fume concentration above the stove and obtains the oil fume concentration value Y5. When the fume hood is placed above the stove, in order to further reduce energy consumption, only the second acquisition unit is used to detect the oil fume concentration in this embodiment.

[0056] S8. The second processing unit determines whether the oil fume concentration value Y5 is greater than Y2. When the oil fume concentration value Y5 is less than Y2, the first acquisition unit is used to detect the oil fume concentration value to obtain the oil fume concentration value Y7. When the oil fume concentration value Y5 at the oil fume escape position of the fume hood is less than Y2, it proves that the cooking oil fume is relatively small at this time. The first acquisition unit is used to detect the oil fume. The first acquisition unit can detect the oil fume more accurately based on its position advantage.

[0057] S9. Set the target oil fume concentration value of the first acquisition unit to Y6; the first calculation unit determines whether the oil fume concentration value Y7 is less than Y6. If so, the fan stops working, and the angle control unit instructs the drive unit to reset the fume hood. By setting the target oil fume concentration value and comparing it with the oil fume concentration value detected by the first acquisition unit, the fume collection stove can automatically shut off after the oil fume is absorbed. This avoids unnecessary energy consumption caused by the user forgetting to turn off the fan, thus improving the convenience and safety of the equipment.

[0060] The data acquisition module is used to collect the concentration value of oil fumes near the stove; specifically, it includes a first acquisition unit set at the end of the fume hood near the stove, and a second acquisition unit set in the direction of oil fume escape from the fume hood; in this embodiment, the first acquisition unit and the second acquisition unit are smoke sensors.

[0061] The data processing module is used to analyze the oil fume concentration data and obtain the processing results; specifically, it includes a first calculation unit for analyzing the oil fume concentration values ​​collected by the first acquisition unit, and a second calculation unit for analyzing the oil fume concentration values ​​collected by the second acquisition unit.

[0062] The smoke purification module includes an execution submodule for smoke purification treatment and a control submodule for controlling the execution submodule. The control submodule includes an angle control unit for adjusting the rotation angle of the smoke collection hood according to the processing result. The execution submodule includes a drive unit for driving the smoke collection hood to rotate according to the instructions of the angle control unit. The drive unit drives the smoke collection hood to rotate around the central axis of the supporting pipe, and the rotatable angle of the smoke collection hood is less than 90 degrees.

[0063] Furthermore, in this embodiment, the control submodule further includes a fan control unit for adjusting the fan's operating mode according to the processing result; the execution submodule further includes a fan unit for adjusting the fan's operating mode according to the instructions of the fan control unit. Specifically, the fan has two operating modes: a high-power operating mode and a low-power operating mode. In the high-power operating mode, the negative pressure of the fan is greater than that in the low-power operating mode.

[0064] Example 4

[0065] Please see Figure 6 This embodiment discloses the control method of the integrated stove fume control system described in Embodiment 3, including the following steps:

[0066] S1. Set the starting oil fume concentration value of the first collection unit to Y1, and the starting oil fume concentration value of the second collection unit to Y2;

[0067] S2. The first collection unit detects the oil fume concentration and obtains the oil fume concentration value Y3. Specifically, since the first collection unit is closer to the stove, it can come into contact with the oil fume first compared to the second collection unit. This setting can reduce the energy consumption when the first and second collection units are turned on at the same time.

[0068] S3. The first calculation unit determines whether the oil fume concentration value Y3 is greater than Y1. If so, step S4 is executed; otherwise, steps S2 and S3 are repeated.

[0069] S4. The second acquisition unit detects the oil fume concentration and obtains the oil fume concentration value Y4.

[0070] S5. The second calculation unit determines whether the oil fume concentration value Y4 is greater than Y2. If so, it runs step S6; otherwise, it repeats steps S4 and S5.

[0071] S6. The angle control unit commands the drive unit to rotate the fume hood, causing it to rotate 30 degrees from its initial position around the central axis of the support pipe to above the stovetop, thus absorbing the cooking fumes. Specifically, when the fume concentration detected by the first and second collection units both reach their respective activation fume concentration values, it indicates that the fume concentration is high. By commanding the drive unit to rotate the fume hood at this point, energy can be saved while achieving precise fume absorption, thus making the fume removal more efficient.

[0072] S7. The second acquisition unit detects the oil fume concentration above the stove and obtains the oil fume concentration value Y5. When the fume hood is placed above the stove, in order to further reduce energy consumption, only the second acquisition unit is used to detect the oil fume concentration in this embodiment.

[0073] S8. The second calculation unit determines whether the oil fume concentration value Y5 is greater than Y2. If so, the fan control unit instructs the fan unit to adjust the fan to a high-power operation mode; otherwise, the fan control unit instructs the fan unit to adjust the fan to a low-power operation mode. After detection by the second acquisition unit, if the oil fume concentration value Y5 is greater than Y2, it indicates that the amount of oil fume is large. In this case, adjusting the fan to a high-power operation mode will efficiently absorb the oil fume, resulting in higher purification efficiency. If the oil fume concentration value Y5 is less than Y2, it indicates that the amount of oil fume is small. Adjusting the fan to a low-power operation mode can save energy while ensuring the oil fume purification effect.

[0074] S9. When the oil fume concentration value Y5 is less than Y2, the first acquisition unit is used to detect the oil fume concentration value to obtain the oil fume concentration value Y7. When the oil fume concentration value Y5 at the oil fume escape position of the fume hood is less than Y2, it proves that the cooking oil fume is relatively small at this time. At this time, the first acquisition unit can detect the oil fume more accurately based on its position advantage.

[0075] S10. Set the target oil fume concentration value of the first acquisition unit to Y6; the first calculation unit determines whether the oil fume concentration value Y7 is less than Y6. If so, the fan control unit instructs the fan unit to turn off the fan, and the angle control unit instructs the drive unit to reset the fume hood. If not, continue to execute S9 and S10. By setting the target oil fume concentration value and comparing it with the oil fume concentration value detected by the first acquisition unit, the fume collection stove can automatically turn off after the oil fume extraction is completed. This will avoid unnecessary energy consumption caused by the user forgetting to turn off the fan, thus improving the convenience and safety of the equipment.
