Description

Technical Field

[0001] This invention relates to home appliance control technology, and more particularly to an airflow control method, device, integrated stove, and storage medium for an integrated stove. Background Technology

[0002] Existing integrated cooktops are generally set with fixed operating parameters under fixed pipeline back pressure. These fixed operating parameters may include the drive current and speed of the integrated cooktop's motor. In actual use, the motor can be controlled to operate at the speed corresponding to the drive current so that the fan can generate airflow.

[0003] In practical use, the back pressure of the ductwork varies in different scenarios, while existing integrated cooktops are set with fixed operating parameters under fixed duct back pressure. Therefore, in special usage scenarios, they cannot simultaneously achieve the goals of removing fumes and reducing noise, resulting in poor flexibility. For example, in some users' homes with high duct pressure, if the set fan speed is used for fume extraction, the high duct pressure will lead to poor fume removal. Conversely, in some users' homes with low duct pressure, if the set fan speed is used for fume extraction, the low duct pressure combined with the integrated cooktop's high fan speed will result in wasted energy and excessive noise. Summary of the Invention

[0004] This invention provides a method, device, integrated stove, and storage medium for controlling the air volume of an integrated stove. It addresses the problem that existing integrated stoves control motors drive the integrated stove's fan according to fixed operating parameters under fixed pipeline back pressure, resulting in poor smoke extraction and inability to effectively reduce noise generated during operation. The invention aims to improve the smoke extraction and noise reduction effects of the integrated stove, providing users with a better experience.

[0005] According to one aspect of the present invention, a method for controlling the airflow of an integrated stove is provided, the method comprising:

[0006] Calculate the actual back pressure of the integrated stove at the outlet of the public pipeline;

[0007] Obtain the required air volume;

[0008] Determine the target drive current required to achieve the required air volume under the actual back pressure of the pipeline;

[0009] The target speed of the motor is determined based on the target drive current, and the motor is controlled to drive the fan of the integrated stove to work at the target speed so that the fan generates the required air volume.

[0010] According to another aspect of the present invention, an airflow control device for an integrated stove is provided, the device comprising:

[0011] The calculation module is used to calculate the actual back pressure of the integrated stove at the outlet of the public pipeline;

[0012] The acquisition module is used to obtain the required air volume;

[0014] The control module is used to determine the target speed of the motor based on the target drive current, and control the motor to drive the fan of the integrated stove to work according to the target speed, so that the fan generates the required air volume.

[0015] According to another aspect of the present invention, an integrated cooktop is provided, the integrated cooktop comprising:

[0016] At least one processor; and

[0017] A memory communicatively connected to the at least one processor; wherein,

[0018] The memory stores a computer program that can be executed by the at least one processor, which is then executed by the at least one processor to enable the at least one processor to perform the airflow control method for the integrated stove according to any embodiment of the present invention.

[0019] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the airflow control method for an integrated stove according to any embodiment of the present invention.

[0020] The technical solution of this invention calculates the actual back pressure of the integrated stove at the outlet of the public pipeline; obtains the required air volume; determines the target drive current required to achieve the required air volume under the actual back pressure of the pipeline; determines the target speed of the motor according to the target drive current, and controls the motor to drive the integrated stove's fan to work according to the target speed, so that the fan generates the required air volume.

This solves the problem of existing integrated stoves controlling the motor to drive the integrated stove's fan according to fixed working parameters under fixed pipeline back pressure, resulting in poor smoke extraction and inability to effectively reduce noise generated during operation. The invention achieves the goal of automatically determining the integrated stove's working parameters corresponding to different actual back pressures of the pipeline, allowing for more accurate and flexible control of the integrated stove's air volume under different actual back pressures, thereby improving the smoke extraction and noise reduction effects of the integrated stove and providing users with a better user experience.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] Figure 1 This is a flowchart illustrating an integrated stove airflow control method provided in an embodiment of the present invention. This embodiment is applicable to situations where an integrated stove is used to remove cooking fumes. The method can be executed by an airflow control device of the integrated stove, which can be implemented in hardware and / or software. The airflow control device can be configured within the integrated stove, which can be a variable frequency integrated stove, etc. Figure 1 As shown, the method may specifically include the following steps:

[0032] S101, calculate the actual back pressure of the integrated stove at the outlet of the public pipeline.

[0033] Among them, pipeline back pressure can be understood as the resistance of the pipeline at the outlet of the public pipeline; pipeline actual back pressure can be understood as the actual back pressure of the pipeline at the outlet of the public pipeline corresponding to the installation position of the integrated stove.

[0034] An integrated cooktop may include a motor, which operates at a corresponding speed based on a given drive current to generate airflow, achieving the purpose of exhausting cooking fumes through the common duct outlet when there is back pressure in the duct. Therefore, by installing and testing the integrated cooktop, the correspondence between the motor drive current, motor speed, and duct back pressure can be obtained and stored in the integrated cooktop's database. This allows for testing the motor speed during installation, and by querying the database based on the motor speed and the given drive current, the actual back pressure at the common duct outlet of the user's integrated cooktop can be determined.

[0035] Therefore, in one optional implementation, the motor of the integrated stove can be controlled to run for a preset time according to a given motor drive current. After the motor has run for the preset time, the average speed of the motor is determined. Based on the motor drive current and the average speed, the correspondence between the motor drive current, the motor speed, and the pipe back pressure stored in the integrated stove's database is queried to obtain the actual pipe back pressure at the outlet of the public pipe for the integrated stove in the user's home. Here, the preset time can be understood as a preset duration.

[0036] For example, the correspondence between motor drive current, motor speed and pipe back pressure can be stored in the database of the integrated stove in the form of a table. Table 1 is a table of correspondence between motor drive current, motor speed and pipe back pressure provided by an embodiment of the present invention.

[0037] Table 1. Correspondence between motor drive current, motor speed, and pipeline back pressure.

[0038] I R X

[0039] Table 1 shows that when the motor drive current is I and the motor speed is R, the corresponding pipe back pressure is X. Assuming that during the installation test of the integrated stove, if the given current is I and the preset duration T is 3 minutes, the motor of the integrated stove can be controlled to run according to the given motor drive current I for the preset duration. After the motor runs for 3 minutes, the average motor speed R is determined. Based on the motor drive current I and the average speed R, the correspondence between the motor drive current, motor speed, and pipe back pressure stored in the integrated stove's database is queried to obtain the actual pipe back pressure at the outlet of the common pipe for the integrated stove in the user's home.

[0040] S102, obtain the required air volume.

[0041] The required air volume can be understood as the amount of air that the fan needs to generate when the integrated stove is actually used.

[0042] In one alternative implementation, after the user selects the desired airflow level, the selected airflow level can be obtained, and the corresponding required airflow can be determined based on the selected airflow level.

[0043] For example, if the air volume is a when the air volume setting is A, and assuming the user selects the air volume setting A, the corresponding required air volume can be determined as a based on the user's selected air volume setting.

[0044] S103, determine the target drive current required to achieve the required air volume under the actual back pressure of the pipeline.

[0045] The target drive current can be understood as the motor drive current required to achieve the required air volume under the actual back pressure of the pipeline.

[0046] In one optional implementation, the actual back pressure of each pipe and the corresponding drive current for each required air volume can be pre-stored in the integrated stove's database. This allows for faster and more accurate determination of the target drive current required to achieve the desired air volume under the actual back pressure by querying the first preset relationship information based on the actual back pressure and required air volume after determining the pipe's actual back pressure. The first preset relationship information includes the drive current corresponding to the actual back pressure of each pipe and each required air volume.

[0047] For example, the first preset relationship information can be stored in the integrated stove's database in the form of a table. Table 2 is a first preset relationship information table provided in an embodiment of the present invention.

[0048] Table 2 First Preset Relationship Information Table

[0049] X W I1

[0050] As shown in Table 2, when the actual back pressure of the pipeline is X and the required air volume is W, the corresponding target drive current is I1. Assuming the required air volume is a and the actual back pressure of the pipeline is X, after determining the actual back pressure of the pipeline is X, the first preset relationship information can be queried based on the actual back pressure of the pipeline (X) and the required air volume (W) to obtain the target drive current I1 required to achieve the required air volume under the actual back pressure of the pipeline.

[0051] S104 determines the target speed of the motor based on the target drive current, and controls the motor to drive the fan of the integrated stove to work according to the target speed so that the fan generates the required air volume.

[0052] The target speed can be understood as the motor speed when the motor is running according to the target drive current.

[0053] In one optional implementation, since the database stores the correspondence between motor drive current, motor speed and pipe back pressure, the target motor speed can be obtained by querying the correspondence between motor drive current, motor speed and pipe back pressure based on the target drive current and the actual pipe back pressure.

[0054] For example, if the actual back pressure of the pipeline is X and the target drive current is I1, the target speed of the corresponding motor is R. Then, the corresponding relationship between the motor drive current, the motor speed and the pipeline back pressure can be found by looking up the target motor drive current (I1) and the actual back pressure of the pipeline (X), and the target speed of the motor is R.

[0055] In this embodiment, based on the actual back pressure of the pipeline and the required air volume, the target drive current required to achieve the required air volume under different actual back pressures of the pipeline is automatically determined. The motor is then controlled to operate at the target speed corresponding to the target drive current, driving the integrated stove's fan to generate the required air volume. This solves the problem of existing integrated stoves where the motor drives the fan according to fixed operating parameters under fixed pipeline back pressure, resulting in poor smoke extraction and inability to effectively reduce noise during operation. The embodiment achieves the goal of automatically determining the integrated stove's operating parameters corresponding to different actual back pressures of the pipeline, allowing for more accurate and flexible control of the integrated stove's air volume under different actual back pressures, thereby improving the smoke extraction and noise reduction effects and providing users with a better experience.

[0056] Figure 2 This is another flowchart illustrating the airflow control method for an integrated stove provided in an embodiment of the present invention. The specific method can be as follows: Figure 2 As shown, the method may include the following steps:

[0057] S201 controls the motor to run for a preset duration according to the preset drive current.

[0058] The preset drive current can be understood as the preset motor drive current when installing and testing the integrated stove.

[0059] In an alternative implementation, the method for obtaining the actual back pressure of the pipeline described above can be developed into an integrated stove pipeline actual back pressure test program. This allows the integrated stove pipeline actual back pressure test program to be started directly during the installation of the integrated stove to test the actual back pressure of the pipeline and automatically calculate the actual back pressure of the pipeline through the pipeline actual back pressure test program.

[0060] For example, Figure 3 A flowchart illustrating the process of obtaining the actual back pressure of the pipeline in the airflow control method for an integrated stove provided in this embodiment of the invention is shown below. Figure 3 As shown, after the integrated stove is installed in the user's home, the actual back pressure test program for the integrated stove pipeline is started. At this time, the motor can be controlled to run according to the preset drive current written in the actual back pressure test program for the integrated stove pipeline.

[0061] S202, determine the average speed of the motor after a preset time.

[0062] For example, see reference Figure 3After the control motor runs for a preset duration according to the preset drive current pre-written in the integrated stove pipeline back pressure test program, the current speed of the motor can be read a preset number of times within a preset reading duration to obtain the current speed of multiple motors. The average speed of the motor is determined based on the obtained current speeds of multiple motors and the preset number of readings. When reading the current speed of the motor a preset number of times within the preset reading duration, the time interval between each speed reading can be equal, which can improve the accuracy of the average speed of the motor.

[0063] If, after the motor runs for a preset duration according to the preset drive current pre-written in the integrated stove pipeline back pressure test program, the current speed of the motor is read 5 times as follows: 200, 200, 220, 210, 210, and the preset number of times is 5, then the average speed of the motor can be determined to be 208 based on the current speed of multiple motors and the preset number of times.

[0064] S203, based on the average rotation speed and actual drive current, query the second preset relationship information to obtain the actual back pressure of the integrated stove at the outlet of the public pipeline. The second preset relationship information includes the pipeline back pressure corresponding to each average rotation speed and each actual drive current.

[0065] The actual driving current can be understood as the DC current that drives the motor to rotate when the integrated stove is installed and tested.

[0066] For example, such as Figure 3 As shown, after determining the average speed of the motor, the actual back pressure of the integrated stove at the outlet of the public pipeline can be obtained by querying the second preset relationship information based on the average speed and the actual drive current.

[0067] In this embodiment, the motor is controlled to run for a preset duration according to a preset drive current. After the preset duration, the average speed of the motor is determined. Based on the average speed and the actual drive current, the second preset relationship information is queried to obtain the actual back pressure of the pipe at the outlet of the integrated stove in the public pipeline. This can more accurately and quickly determine the actual back pressure of the pipe at the outlet of the integrated stove in the public pipeline, thereby improving the air volume control efficiency and speed of the integrated stove.

[0068] Optionally, after step S203, an alarm can be triggered based on the actual back pressure of the pipeline. Figure 4 This is a flowchart illustrating the alarm prompt based on the actual back pressure of the pipeline in the airflow control method of the integrated stove provided in this embodiment of the invention. The specific method is as follows: Figure 4 As shown, the method may include the following steps:

[0069] S2031, determine the back pressure level to which the actual back pressure of the pipeline belongs.

[0070] In one optional implementation, it can be determined whether the actual back pressure of the pipeline exceeds a first preset pipeline back pressure; if the actual back pressure of the pipeline does not exceed the first preset pipeline back pressure, the back pressure level of the actual back pressure of the pipeline is determined to be preferred.

[0071] When the actual back pressure of the pipeline exceeds the first preset pipeline back pressure, determine whether the actual back pressure of the pipeline exceeds the second preset pipeline back pressure. The first preset pipeline back pressure is less than the second preset pipeline back pressure. When the actual back pressure of the pipeline does not exceed the second preset pipeline back pressure, determine that the back pressure level of the actual back pressure of the pipeline is good. This can more accurately and quickly determine the back pressure level to which the actual back pressure of the pipeline belongs, thereby improving the air volume control efficiency and speed of the integrated stove.

[0072] The first preset pipeline back pressure is less than the second preset pipeline back pressure.

[0073] When the actual back pressure of the pipeline exceeds the second preset pipeline back pressure, the back pressure level of the actual back pressure of the pipeline is determined to be the difference.

[0074] For example, such as Figure 3 As shown, the first preset pipeline back pressure can be 200, and the second preset pipeline back pressure can be 450. If the actual pipeline back pressure does not exceed the first preset pipeline back pressure (200), the back pressure level of the actual pipeline back pressure can be determined to be excellent; if the actual pipeline back pressure exceeds the second preset pipeline back pressure (200), the back pressure level of the actual pipeline back pressure can be determined to be poor; if the actual pipeline back pressure is within the numerical range of the first preset pipeline back pressure (200) and the second preset pipeline back pressure (450), the back pressure level of the actual pipeline back pressure can be determined to be good.

[0075] Assuming the actual back pressure of the pipeline is determined to be 460, after determining the actual back pressure of the pipeline, by comparing the actual back pressure of the pipeline, the first preset pipeline back pressure, and the second preset pipeline back pressure, it can be determined that the actual back pressure of the pipeline exceeds the second preset pipeline back pressure. Therefore, when the actual back pressure of the pipeline is 460, the back pressure level is poor.

[0076] S2032, determine whether to issue an alarm based on the back pressure level.

[0077] Back pressure level can be understood as the resistance level of a pipeline at the outlet of a public pipeline. Back pressure level can be divided into three levels: excellent, good, and poor. The smaller the back pressure value, the higher the back pressure level of the pipeline.

[0078] In one alternative implementation, it can be determined whether the back pressure level is poor, and an alarm is triggered when the back pressure level is poor.

[0079] For example, such as Figure 3As shown, after determining the back pressure level, the actual back pressure of the pipeline can be displayed; if the back pressure level is poor, the back pressure level can be displayed on the terminal device and an alarm can be triggered.

[0080] In this embodiment, the back pressure level of the actual back pressure in the pipeline is determined, and an alarm is triggered based on the back pressure level. This allows for real-time determination of the back pressure level during integrated stove installation. When the back pressure level is low, the user is promptly reminded to maintain the fan and pipeline, ensuring good fume extraction performance during subsequent use. This avoids situations where the user mistakenly believes the poor fume extraction is due to a quality issue, leading to incorrect complaints and returns, and also reduces additional repair and replacement costs caused by false complaints. By identifying issues with poor fume extraction due to low back pressure during initial installation, this method improves the user experience.

[0081] S204, obtain the required air volume.

[0082] S205, based on the actual back pressure of the pipeline and the required air volume, query the first preset relationship information to obtain the target drive current required to achieve the required air volume under the actual back pressure of the pipeline. The first preset relationship information includes the drive current corresponding to the actual back pressure of each pipeline and the required air volume.

[0083] In an optional implementation, the first preset relationship information can be stored in the integrated stove's database in the same table format as Table 2.

[0084] In this embodiment, the target driving current required to achieve the required air volume under the actual back pressure of the pipeline is obtained by querying the first preset relationship information based on the actual back pressure of the pipeline and the required air volume. This allows for a faster and more accurate determination of the target driving current required to achieve the required air volume under the actual back pressure of the pipeline, thereby improving the air volume control efficiency and speed of the integrated stove.

[0085] S206, obtain the recommended speed corresponding to the target drive current.

[0086] The recommended speed can be understood as the motor speed corresponding to the target drive current.

[0087] In one alternative implementation, the motor speed can be obtained by querying a second preset relationship information based on the target drive current and the actual back pressure of the pipeline, and then the motor speed can be determined as the recommended speed.

[0088] S207, showing the recommended RPM.

[0089] In this embodiment, the recommended speed corresponding to the target drive current is obtained and displayed. This can recommend a speed corresponding to the target drive current to the user, increasing the intelligence and flexibility of the integrated stove.

[0090] S208, determine whether a recommended speed adjustment command has been received. If no recommended speed adjustment command has been received, proceed to step S213; if a recommended speed adjustment command has been received, proceed to step S209.

[0091] In one optional implementation, after determining the recommended speed, the recommended speed can be sent to a terminal device bound to the integrated stove, which then displays the recommended speed to the user. If the user believes the current recommended speed needs adjustment, they can click the speed adjustment component on the recommended speed display page to trigger the terminal device to send an adjustment command to the integrated stove, and then receive the adjustment command. If the user believes the current recommended speed does not need adjustment, they can click the confirmation component on the recommended speed display page, and then receive an instruction to set the recommended speed as the target speed. This allows the user to choose whether to adjust the recommended speed, providing a more personalized service and improving the user experience.

[0092] S209 displays the page for adjusting the recommended engine speed.

[0093] S210, obtain the speed offset number of the input recommended speed from the adjustment page.

[0094] The speed offset number can be understood as the speed compensation value. The compensation value can be positive or negative. For example, the speed offset number can be 1 or -1.

[0095] In one optional implementation, after receiving the recommended speed adjustment command, a recommended speed adjustment page can be displayed to the user on the human-machine interface display screen of the terminal device or integrated stove. The user can input the recommended speed offset number on the adjustment page. After the user inputs the recommended speed offset number and clicks the "Confirm" component on the adjustment page, the input recommended speed offset number is retrieved from the adjustment page. In this way, the user can adjust the recommended speed value on the human-machine interface display screen of the terminal device or integrated stove, providing the user with a more personalized service and increasing the convenience and intelligence of using the integrated stove.

[0096] S211, determine whether the speed offset number is within the preset offset value range. If the speed offset number is not within the preset offset value range, execute step S213; if the speed offset number is within the preset offset value range, execute step S212.

[0097] The preset offset value range can be understood as the absolute value range of a preset speed offset number. For example, the preset offset value range could be [-3, 3].

[0098] In one alternative implementation, the speed offset number can be determined to be within the preset offset value range by comparing the speed offset number with the maximum offset number and the minimum offset number within the preset offset value range.

[0099] For example, if the preset bias value range is [-3, 3] and the speed bias number is 2, it can be determined that -3 < 2 < 3, and therefore the speed bias number belongs to the preset bias value range.

[0100] S212 determines the target speed based on the speed offset number and the recommended speed.

[0101] In one optional implementation, there is a certain correspondence between the motor drive current, the speed offset number, and the motor speed. This correspondence can be pre-stored in the integrated stove's database. After obtaining the speed offset number, the correspondence between the motor drive current, the speed offset number, and the motor speed can be queried based on the speed offset number and the target drive current to determine the motor speed corresponding to the speed offset number and the target drive current. If the motor speed corresponding to the speed offset number and the target drive current is the same as the recommended speed, then step S213 is executed. If the motor speed corresponding to the speed offset number and the target drive current is different from the recommended speed, then the motor speed corresponding to the speed offset number and the target drive current is determined as the target speed. This allows for timely determination of the recommended speed as the target speed when the speed offset number is not within the preset offset value range, avoiding the problem of the target speed determined based on the speed offset number and the recommended speed not matching the target drive current, which could lead to the fan not generating the required air volume, thus improving the air volume control efficiency of the integrated stove.

[0102] For example, if the recommended speed is R, the speed offset number is 1, and the target drive current is I1, the corresponding relationship between the motor drive current, the speed offset number, and the motor speed can be queried based on the speed offset number and the target drive current. The speed of the motor corresponding to the speed offset number and the target drive current is determined to be R1. The speed of the motor corresponding to the speed offset number and the target drive current is the same as the recommended speed. Therefore, the speed of the motor (R1) corresponding to the speed offset number (1) and the target drive current (I1) is determined as the target speed.

[0103] After executing step S212, execute step S214.

[0104] S213, the recommended speed is set as the target speed.

[0105] S214 controls the motor to drive the integrated stove's fan at the target speed so that the fan generates the required air volume.

[0106] In this embodiment, based on the actual back pressure of the pipeline and the required air volume, the target drive current required to achieve the required air volume under different actual back pressures of the pipeline is automatically determined. The motor is then controlled to operate at the target speed corresponding to the target drive current, driving the integrated stove's fan to generate the required air volume. This solves the problem of existing integrated stoves where the motor drives the fan according to fixed operating parameters under fixed pipeline back pressure, resulting in poor smoke extraction and inability to effectively reduce noise during operation. The embodiment achieves the goal of automatically determining the integrated stove's operating parameters corresponding to different actual back pressures of the pipeline, allowing for more accurate and flexible control of the integrated stove's air volume under different actual back pressures, thereby improving the smoke extraction and noise reduction effects and providing users with a better experience.

[0143] In another aspect, the present invention also provides a computer-readable medium, which may be included in the device described in the above embodiments; or it may exist independently and not assembled into the device. The computer-readable medium carries one or more programs, which, when executed by the device, cause the device to include:

[0144] Calculate the actual back pressure of the integrated stove at the outlet of the public pipeline; obtain the required air volume; determine the target drive current required to achieve the required air volume under the actual back pressure of the pipeline; determine the target speed of the motor based on the target drive current, and control the motor to drive the fan of the integrated stove to work according to the target speed so that the fan generates the required air volume.

[0145] The technical solution of this invention automatically determines the target drive current required to achieve the required air volume under different actual back pressures of the pipeline, based on the actual back pressure of the pipeline and the required air volume. The motor is then controlled to operate at the target speed corresponding to the target drive current, driving the integrated stove's fan to generate the required air volume. This solves the problem of existing integrated stoves where the motor drives the fan according to fixed operating parameters under fixed pipeline back pressure, resulting in poor smoke extraction and inability to effectively reduce noise during operation. The invention achieves the goal of automatically determining the operating parameters of the integrated stove corresponding to different actual back pressures of the pipeline, enabling more accurate and flexible control of the integrated stove's air volume under different actual back pressures, thereby improving the smoke extraction and noise reduction effects and providing users with a better experience.
