Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a control system, method and storage medium for an intelligent fragrance-absorbing refrigerator. Background Technology

[0002] This application relates to the field of household appliance technology, and more particularly to a control system for an intelligent fragrance-absorbing refrigerator. Refrigerators, as essential household appliances for food preservation, often develop unpleasant odors during long-term use due to food spoilage, bacterial growth, and cross-contamination, affecting food preservation and user experience. To improve the odor environment inside the refrigerator, existing technologies include installing fragrance slow-release modules or deodorizing devices within the refrigerator.

[0003] An existing refrigerator odor removal solution includes an odor sensor and a slow-release device installed inside the refrigerator's storage cavity. The slow-release device stores odor-removing material. A processor component determines the concentration of target odor molecules within the storage cavity based on the odor sensor. If the concentration of the target odor molecules is greater than or equal to a certain preset concentration value, the processor controls the slow-release device to open and release the odor-removing material. This solution achieves passive odor removal by detecting odor concentration with an odor sensor and triggering release.

[0004] However, existing technical solutions rely solely on a single threshold of odor concentration to turn the fragrance release module on or off. They do not adjust the release parameters of the fragrance release module based on the temperature data inside the refrigerator compartment, and ignore the significant impact of temperature changes on the fragrance evaporation rate. This can easily lead to insufficient release at low temperatures and excessive release at high temperatures, making it impossible to achieve precise and on-demand fragrance release and thus failing to achieve a stable and efficient odor neutralization effect.

[0020] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0021] In the field of refrigerator deodorization technology, existing solutions for removing refrigerator odors often rely solely on a single odor sensor for on / off control, without considering the impact of temperature changes on the fragrance evaporation rate. In low-temperature environments, the fragrance evaporation rate decreases, resulting in an actual release effect far lower than expected, failing to achieve a stable and consistent deodorization effect. Furthermore, when temperatures fluctuate, the release intensity cannot be dynamically adjusted, easily leading to insufficient release or excessive waste.

[0022] To address the aforementioned problems, some embodiments of this application provide a control system for an intelligent fragrance-absorbing refrigerator. See also... Figure 1 and Figure 2 ,include: Fragrance slow-release module 10, temperature sensor 20, odor sensor 30 and controller 40.

[0023] The fragrance slow-release module 10 is located in the air duct of the refrigerator compartment. The fragrance slow-release module 10 is an actuator for storing and releasing fragrance. Its location in the air duct allows it to utilize the refrigerator's existing air circulation system to evenly distribute the released fragrance molecules throughout the entire refrigerator space. The fragrance slow-release module 10 can be implemented in various ways. For example, it can be a replaceable capsule structure with a sealed food-grade plastic shell, and its interior filled with microcapsule particles made of food-grade tea tree oil fragrance core material coated with β-cyclodextrin as the wall material.

[0024] Temperature sensor 20 is disposed in the refrigerator compartment. Temperature sensor 20 is a detection component used to detect temperature data in the refrigerator compartment in real time. The installation position of temperature sensor 20 should accurately reflect the temperature conditions of the environment where fragrance release module 10 is located.

[0025] Odor sensor 30 is located at the return air vent of the refrigerator compartment. Odor sensor 30 is a detection component used to detect the concentration of odors in the air inside the refrigerator compartment. The location of odor sensor 30 at the return air vent of the refrigerator compartment allows it to capture air samples drawn back from the refrigerator compartment in real time during airflow circulation.

[0026] The controller 40 is electrically connected to the odor sensor 30, the temperature sensor 20, and the fragrance slow-release module 10. The controller 40 is used to receive the odor concentration signal output by the odor sensor 30 and the temperature signal output by the temperature sensor 20. The controller 40 is used to generate control commands based on the odor concentration signal and the temperature signal, and the controller 40 is used to send the control commands to the fragrance slow-release module 10.

[0027] Controller 40 is configured as follows: Acquire odor concentration data detected by odor sensor 30; Based on the odor concentration data, the preset release parameters of the fragrance slow-release module 10 are determined; Acquire temperature data detected by temperature sensor 20; Temperature compensation is performed on preset release parameters based on temperature data to generate target release parameters for fragrance slow-release module 10. Control commands are generated based on the target release parameters. These commands are used to control the fragrance release module 10 to perform a release operation according to the target release parameters.

[0028] Specifically, after the controller 40 acquires the odor concentration data detected by the odor sensor 30, it determines the preset release parameters of the fragrance slow-release module 10 based on the data.

[0029] The controller 40 determines the preset release parameters of the fragrance release module 10 based on the odor concentration data. The preset release parameters are the baseline release intensity of the fragrance release module 10 without considering the influence of temperature. There is a corresponding relationship between the preset release parameters and the odor concentration data; the higher the odor concentration, the larger the preset release parameters.

[0030] The controller 40 acquires temperature data detected by the temperature sensor 20, and the temperature data reflects the real-time temperature inside the refrigerator compartment.

[0031] The controller 40 performs temperature compensation on the preset release parameters based on temperature data to generate the target release parameters for the fragrance slow-release module 10. Temperature compensation refers to adjusting the preset release parameters according to the current temperature to counteract the impact of temperature changes on the fragrance evaporation rate. The target release parameter is the final release intensity to be achieved after temperature compensation.

[0032] The controller 40 generates a control command based on the target release parameters and sends the control command to the fragrance release module 10. The control command is used to control the fragrance release module 10 to perform the release operation according to the target release parameters.

[0033] As can be seen from the above technical solution, this embodiment uses the controller 40 to acquire odor concentration data to determine preset release parameters, acquires temperature data to perform temperature compensation on the preset release parameters to generate target release parameters, and controls the fragrance slow-release module 10 to perform the release operation according to the target release parameters. This embodiment solves the problem that the prior art does not consider the influence of temperature changes on the fragrance evaporation rate, avoids insufficient release at low temperatures and excessive release at high temperatures, realizes on-demand release, and ensures the consistency of release effect at different temperatures.

[0034] To further clarify the specific implementation method of temperature compensation, see the following in some embodiments: Figure 1 and Figure 2The control system of the intelligent fragrance deodorizing refrigerator also includes a memory 50, which contains a temperature-release parameter compensation table. The memory 50 is electrically connected to the controller 40.

[0035] When the controller 40 performs temperature compensation on the preset release parameters of the fragrance release module 10 based on temperature data and generates the target release parameters of the fragrance release module 10, the controller 40 is specifically configured as follows: Based on temperature data and a temperature-release parameter compensation table, the compensation coefficient is obtained; The compensation coefficient is multiplied by the preset release parameter to generate the target release parameter of the fragrance slow-release module 10.

[0036] Specifically, after acquiring the temperature data detected by the temperature sensor 20, the controller 40 accesses the pre-stored temperature-release parameter compensation table in the memory 50 based on the temperature data. The temperature-release parameter compensation table records the compensation coefficients corresponding to different temperature values. The controller 40 searches the temperature-release parameter compensation table for the compensation coefficient corresponding to the current temperature data.

[0037] The temperature-release parameter compensation table was obtained through experimental calibration. The table records the compensation coefficients required to achieve the same release effect as the reference temperature of 5°C at different temperatures. The temperature-release parameter compensation table is shown below:

[0038] After obtaining the compensation coefficient, the controller 40 multiplies the compensation coefficient with the preset release parameter determined based on the odor concentration data according to the following formula: Target release parameter = preset release parameter × compensation coefficient The result of multiplying the compensation coefficient by the preset release parameter is the target release parameter of the fragrance sustained-release module 10.

[0039] As can be seen from the above technical solution, in this embodiment, the temperature-release parameter compensation table is pre-stored in the memory 50. The controller 40 obtains the compensation coefficient based on the temperature data and the temperature-release parameter compensation table, and multiplies the compensation coefficient with the preset release parameter to generate the target release parameter. This embodiment clarifies the specific implementation method of temperature compensation, obtaining the compensation coefficient by looking up the table and performing multiplication, thereby realizing temperature-based adjustment of the release parameter.

[0040] In some embodiments, see Figure 1 and Figure 2 Controller 40 is also configured as follows: Real-time acquisition of odor concentration data detected by odor sensor 30; When the odor concentration data exceeds the preset freshness threshold, the steps of determining the preset release parameters based on the odor concentration data, acquiring the temperature data detected by the temperature sensor 20, and generating the target release parameters are then executed.

[0041] Specifically, the controller 40 acquires odor concentration data detected by the odor sensor 30 in real time. The controller 40 compares the real-time acquired odor concentration data with a preset freshness threshold. When the controller 40 determines that the odor concentration data exceeds the preset freshness threshold, the controller 40 initiates the release operation process, executing the steps of generating target release parameters based on the odor concentration data and temperature data, and controlling the fragrance slow-release module 10 to perform the release operation based on the target release parameters.

[0042] As can be seen from the above technical solution, this embodiment obtains odor concentration data in real time through controller 40 and compares it with a preset freshness threshold. When the odor concentration data exceeds the preset freshness threshold, the release operation is initiated, thus realizing the release operation is initiated on demand.

[0043] In some embodiments, see Figure 1 and Figure 2 The controller 40 is also configured as follows: During the process of controlling the fragrance release module 10 to perform the release operation, the temperature data of the temperature sensor 20 is acquired in real time. The target release parameters are updated in real time based on the acquired temperature data.

[0044] Specifically, during the release operation controlled by the controller 40 and the fragrance release module 10, the temperature sensor 20 continuously monitors the temperature data inside the refrigerator compartment and sends the temperature data to the controller 40. After acquiring the real-time temperature data, the controller 40 re-compensates the preset release parameters based on the current real-time temperature data to generate updated target release parameters. The controller 40 generates new control commands based on the updated target release parameters and sends the new control commands to the fragrance release module 10, controlling the fragrance release module 10 to perform the release operation according to the updated target release parameters. For example, if the refrigerator compartment temperature rises due to frequent door opening and closing during the release process, the controller 40 acquires the increased temperature data, regenerates a smaller target release parameter based on the increased temperature data, and controls the fragrance release module 10 to reduce the release intensity.

[0045] As can be seen from the above technical solution, this embodiment achieves dynamic response to temperature fluctuations by having the controller 40 acquire temperature data in real time and update the target release parameters in real time during the release process, thereby further ensuring the consistency of the release effect.

[0046] In some embodiments, see Figure 1 and Figure 2The fragrance release module 10 is equipped with a fragrance release hole, which is an outlet structure for releasing fragrance outward.

[0047] The preset release parameters correspond to the opening degree of the fragrance release vent, and the specific correspondence is as follows: the odor concentration is in the range of 1000ppm to 1500ppm, which is low-end, and the preset release parameter is 10% opening degree; the odor concentration is in the range of 1500ppm to 2000ppm, which is medium-end, and the preset release parameter is 40% opening degree; the odor concentration is greater than 2000ppm, which is high-end, and the preset release parameter is 70% opening degree.

[0048] Taking an odor concentration in the medium range as an example, the corresponding preset release parameter is 40% opening. When the temperature data detected by temperature sensor 20 is 2℃, the compensation coefficient is found to be 1.8 according to the pre-stored temperature-release parameter compensation table, so the target release parameter is 40% × 1.8 = 72% opening. When the temperature data detected by temperature sensor 20 is 8℃, the compensation coefficient is found to be 0.7, so the target release parameter is 40% × 0.7 = 28% opening.

[0049] When the controller 40 executes the control command generated according to the target release parameters, it is specifically configured to: generate the control command according to the target release parameters, and the control command is used to adjust the opening of the fragrance release hole so as to control the fragrance slow release module 10 to perform the release operation according to the target release parameters.

[0050] For example, when the target release parameter is 72% opening, the controller 40 generates a control command based on the target release parameter of 72% to adjust the opening of the fragrance release hole to 72%. When the target release parameter is 28% opening, the controller 40 generates a control command based on the target release parameter of 28% to adjust the opening of the fragrance release hole to 28%.

[0051] The fragrance release module 10 is internally filled with microcapsule particles made of food-grade tea tree oil fragrance core material coated with β-cyclodextrin as the wall material. A sliding-cover valve driven by a micro-stepper motor is located at one end of the housing of the fragrance release module 10. This valve serves as a controllable release port, with the fragrance release orifice located at this valve. The opening of the fragrance release orifice is controlled by this valve. The valve is normally closed, but upon receiving a control command, it can adjust its opening size, thereby changing the opening of the fragrance release orifice. After receiving a control command, the fragrance release module 10 adjusts the opening of the fragrance release orifice by driving the sliding-cover valve with the stepper motor, ensuring that the fragrance release is performed according to the target release parameters.

[0052] As can be seen from the above technical solution, in this embodiment, the fragrance release module 10 is set with a fragrance release hole, and the controller 40 controls the release operation by adjusting the opening of the fragrance release hole, thereby realizing the specific execution of the target release parameters.

[0053] In some embodiments, see Figure 1 and Figure 2 The controller 40 is also configured as follows: After the controller 40 controls the fragrance release module 10 to perform the release operation for a first preset time, the controller 40 acquires the odor concentration data detected by the odor sensor 30. If the odor concentration drops to the first preset concentration threshold, reduce the opening of the fragrance release pore.

[0054] Specifically, the first preset duration is a pre-set time length, such as 30 minutes. The first preset concentration threshold is a critical value related to the odor concentration level, such as the lower limit of the odor concentration range for the current level. Based on the previous settings, the odor concentration levels are divided as follows: low level corresponds to the 1000ppm to 1500ppm range, medium level corresponds to the 1500ppm to 2000ppm range, and high level corresponds to greater than 2000ppm. Each level corresponds to a preset release parameter: low level 10% opening, medium level 40% opening, and high level 70% opening. Taking an initial odor concentration falling into the medium range as an example, assuming an initial odor concentration of 1800ppm, the controller 40 determines the preset release parameter as 40% opening based on the medium level and performs temperature compensation to generate the target release parameter. For example, when the temperature is 2℃, the target release parameter is 40% × 1.8 = 72% opening; when the temperature is 8℃, the target release parameter is 40% × 0.7 = 28% opening. The controller 40 controls the fragrance release hole 11 to perform the release operation at the corresponding opening degree.

[0055] After the release operation continues for a first preset duration (e.g., 30 minutes), the controller 40 acquires the odor concentration data detected by the odor sensor 30 again. If the odor concentration drops below 1500ppm at this time (i.e., below the lower limit of the medium range), it indicates that the odor level has been reduced to the low range. The controller 40 then determines that the opening of the fragrance release hole 11 needs to be reduced, and the release intensity is adjusted to the target opening after the preset release parameters corresponding to the low range are compensated for by the current temperature.

[0056] As can be seen from the above technical solution, in this embodiment, the controller 40 obtains odor concentration data after releasing for a first preset duration, and reduces the opening of the fragrance release hole when the odor concentration drops to the first preset concentration threshold, thereby realizing the dynamic adjustment of the release intensity according to the change of odor intensity and avoiding excessive release.

[0057] In some embodiments, see Figure 1 and Figure 2 The controller 40 is also configured to completely close the fragrance release hole when the odor concentration data is lower than the preset shut-off threshold.

[0058] Specifically, the controller 40 internally stores a preset shut-off threshold, which is lower than a preset freshness threshold. During the release operation, the controller 40 continuously or periodically acquires odor concentration data detected by the odor sensor 30. The controller 40 compares the odor concentration data with the preset shut-off threshold. When the odor concentration data is lower than the preset shut-off threshold, it indicates that the odor in the refrigerator compartment has been effectively neutralized, and the controller 40 generates a shut-off command to completely close the fragrance release vent. After the fragrance release vent is completely closed, the fragrance release module 10 stops releasing, and the system enters a standby monitoring state.

[0059] As can be seen from the above technical solution, in this embodiment, the controller 40 controls the fragrance release hole to be completely closed when the odor concentration data is lower than the preset closing threshold, thereby achieving automatic stopping after the odor is eliminated and avoiding unnecessary fragrance consumption.

[0060] In some embodiments, see Figure 1 The control system of the intelligent fragrance-removing refrigerator also includes a display module 60. The display module 60 is located on the refrigerator door and is electrically connected to the controller 40.

[0061] Controller 40 is also configured as follows: Based on the cumulative usage of the fragrance release module 10, the remaining usage time of the fragrance capsules in the fragrance release module 10 is calculated, and when the remaining usage time is lower than the preset lifespan threshold, the display module 60 is controlled to output a replacement prompt message.

[0062] Specifically, the cumulative usage includes at least one of the following: cumulative opening time, cumulative release count, or cumulative release amount of the fragrance release module 10. The controller 40 calculates the remaining usage time of the fragrance capsule by recording parameters such as the total valve opening time or release count of the fragrance release module 10, combined with a preset total lifespan. The controller 40 internally stores a preset lifespan threshold. When the calculated remaining usage time is lower than the preset lifespan threshold, the controller 40 controls the display module 60 to output a replacement prompt. The replacement prompt can be in the form of text prompts, icon displays, or flashing indicator lights, used to remind the user to replace the fragrance capsule in time. After seeing the prompt, the user can push in a new fragrance capsule through a dedicated window on the inner wall of the refrigerator compartment to replace it.

[0063] As can be seen from the above technical solution, in this embodiment, the display module 60 is electrically connected to the controller 40. The controller 40 calculates the remaining usage time based on the cumulative usage and outputs a replacement prompt when the time is lower than the preset lifespan threshold, thereby realizing proactive reminders to users, making it convenient for users to replace the fragrance capsules in a timely manner, and ensuring the continuous and effective operation of the system.

[0064] In some embodiments, see Figure 3This application also provides a control method for an intelligent fragrance-absorbing refrigerator, applied to the control system of the intelligent fragrance-absorbing refrigerator provided in the above embodiments, including: S100: Acquire odor concentration data detected by odor sensor 30; S200. Based on the odor concentration data, determine the preset release parameters of the fragrance slow-release module 10; S300: Acquire temperature data detected by temperature sensor 20; S400: Based on temperature data, perform temperature compensation on preset release parameters to generate target release parameters for fragrance slow-release module 10; S500: Generate control instructions based on the target release parameters to control the fragrance slow-release module 10 to perform the release operation according to the target release parameters.

[0065] In some embodiments, this application also provides a computer-readable storage medium, including: at least one computer instruction, the computer instruction being used to cause the computer to perform the steps of the control method for the intelligent fragrance deodorizing refrigerator provided in the above embodiments.

[0066] When computer instructions are loaded and executed by the computer, the computer can perform the steps of the control method for the intelligent fragrance deodorizing refrigerator, including but not limited to: acquiring odor concentration data detected by odor sensor 30; determining preset release parameters of fragrance slow-release module 10 based on odor concentration data; acquiring temperature data detected by temperature sensor 20; performing temperature compensation on the preset release parameters based on temperature data to generate target release parameters for fragrance slow-release module 10; and generating control instructions based on target release parameters to control fragrance slow-release module 10 to perform release operations according to target release parameters.

[0067] Specifically, the computer-readable storage medium can be a USB flash drive, external hard drive, read-only memory, random access memory, magnetic disk, or optical disk, or any other medium capable of storing program code. When the computer (such as the processor or microcontroller in the refrigerator control module) loads and executes the aforementioned computer instructions, the computer acquires odor concentration data detected in real time by the odor sensor 30. This odor concentration data reflects the severity of the odor in the refrigerator compartment. The computer determines the preset release parameters of the fragrance release module 10 based on the odor concentration data. There is a corresponding relationship between the preset release parameters and the odor concentration data; the higher the odor concentration, the larger the preset release parameters. The computer acquires temperature data detected by the temperature sensor 20. This temperature data reflects the real-time temperature inside the refrigerator compartment. Based on the temperature data, the computer performs temperature compensation on the preset release parameters to generate the target release parameters for the fragrance release module 10. The computer generates control instructions based on the target release parameters and sends these instructions to the fragrance release module 10, controlling the fragrance release module 10 to perform the release operation according to the target release parameters.

[0068] For example, when the odor concentration data is 1600ppm, the computer determines the corresponding preset release parameter to be 40% based on the odor concentration data; when the temperature data is 5℃, the computer performs temperature compensation on the preset release parameter of 40% based on the 5℃ temperature data to generate the target release parameter; the computer generates control instructions based on the target release parameter to control the fragrance slow-release module 10 to perform the release operation.

[0069] By executing the aforementioned computer instructions, the computer can control the intelligent fragrance-removing refrigerator according to preset logic, completing the on-demand fragrance release operation based on the linkage of dual sensors for odor concentration and temperature. This process ensures consistent release effects under different temperature conditions, avoiding insufficient release at low temperatures and excessive release at high temperatures, thereby improving the refrigerator's odor removal efficiency and user experience.

[0070] As can be seen from the above technical solution, the computer-readable storage medium provided in this embodiment stores a computer program or instruction that implements the above control method, so that when the processor executes the program or instruction, it can generate target release parameters based on odor concentration data and temperature data and control the fragrance slow-release module 10 to perform the release operation. This solves the problem that the prior art does not consider the influence of temperature changes on the fragrance evaporation rate, avoids insufficient release at low temperatures and excessive release at high temperatures, realizes release on demand and ensures the consistency of release effect at different temperatures.
