Description

Technical Field

[0001] The present invention relates to the field of kitchen appliance technology, and in particular to a range hood control method, device, range hood and storage medium. Background Technology

[0002] Currently, range hoods have become an indispensable home appliance in people's lives. Range hoods are installed above the kitchen stove and can quickly remove the waste from the stove and the oil fumes produced during cooking and exhaust them outdoors, thereby reducing indoor pollution and purifying indoor air.

[0003] In related technologies, when the range hood is in constant airflow mode, the constant exhaust volume of the range hood is controlled by detecting the motor operating parameters. When the resistance of the flue increases or the flue is blocked, the range hood will increase its speed to ensure that the exhaust volume remains constant. At this time, the noise of the range hood will increase significantly, causing annoyance to the user. If the range hood is small, the speed of the range hood cannot be controlled according to the actual needs. Summary of the Invention

[0004] This invention provides a range hood control method, device, range hood, and storage medium, which can avoid the noise problem caused by high rotation speed when there is little oil smoke. The range hood speed can be controlled according to actual needs, so as to meet actual needs while timely exhaust of oil smoke.

[0005] In a first aspect, embodiments of the present invention provide a range hood control method, comprising:

[0006] If the noise level of the range hood is detected to be greater than the preset value during the operation of the range hood in constant airflow mode, the smoke level of the oil fume will be monitored by the infrared oil fume identification module.

[0007] If the detected smoke level is greater than the set smoke threshold, the range hood will continue to operate in constant airflow mode.

[0008] If the detected smoke level is less than the set smoke threshold, the range hood is controlled to exit the constant airflow mode, and the speed of the range hood is reduced to the set speed based on the monitored environmental information.

[0009] Secondly, embodiments of the present invention also provide a range hood control device, comprising:

[0010] The monitoring module is used to monitor the smoke level of the range hood by means of an infrared smoke identification module if the noise level of the range hood is detected to be greater than a preset value during the operation of the range hood in constant air volume mode.

[0011] The first control module is used to control the range hood to continue operating in constant airflow mode if the detected smoke value is greater than a set smoke threshold.

[0012] The second control module is used to control the range hood to exit the constant airflow mode if the detected smoke value is less than the set smoke threshold, and to reduce the speed of the range hood to the set speed based on the detected environmental information.

[0013] Thirdly, embodiments of the present invention also provide a range hood, comprising:

[0014] One or more processors;

[0015] Storage device for storing one or more programs.

[0016] When the one or more programs are executed by the one or more processors, the one or more processors perform the method provided in this embodiment of the invention.

[0017] Fourthly, embodiments of the present invention provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method provided in the embodiments of the present invention.

[0018] The technical solution provided by this invention, during the operation of a range hood in constant airflow mode, if the noise level of the range hood is detected to be greater than a preset value, the smoke level of the oil fumes is monitored via an infrared smoke identification module. If the detected smoke level is greater than a set smoke threshold, the range hood is controlled to continue operating in constant airflow mode. If the detected smoke level is less than the set smoke threshold, the range hood is controlled to exit constant airflow mode, and the speed of the range hood is reduced to a set speed based on the monitored environmental information. In other words, when the range hood is operating in constant airflow mode, if the noise level of the range hood is greater than a preset value, the smoke level of the oil fumes is monitored. If the detected smoke level is greater than a set smoke threshold, the range hood is controlled to operate in constant airflow mode, which can ensure that the oil fumes in the kitchen are discharged in a timely manner. If the detected smoke level is less than the set smoke threshold, it can ensure that the oil fumes are discharged in a timely manner when there are few oil fumes, which can save power consumption. It can also control the speed of the range hood according to different environmental needs, meeting the actual situation while timely discharging oil fumes, thus increasing practicality.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0027] Figure 1 This is a flowchart of a range hood control method provided by an embodiment of the present invention. The method can be executed by a range hood control device, which can be implemented by software and / or hardware. The device can be configured in the range hood, and the method can be applied to a range hood operating in constant airflow mode.

[0028] like Figure 1 As shown, the technical solution provided by the embodiments of the present invention includes:

[0029] S110: When the range hood is operating in constant airflow mode, if the noise level of the range hood is detected to be greater than the preset value, the smoke level of the oil fume will be monitored through the infrared oil fume identification module.

[0030] In this embodiment of the invention, if the duct is blocked or the duct resistance causes poor smoke extraction during constant airflow operation of the range hood, the range hood needs to increase its rotation speed to maintain a constant airflow. However, the higher the rotation speed, the louder the noise, which can affect the user. Therefore, it is necessary to monitor the smoke level and control the range hood's rotation speed based on the smoke level to avoid significant impact on the user.

[0031] In this embodiment of the invention, optionally, the noise level of the range hood can be monitored using a microphone module. Generally, when the noise level is high, the range hood's rotation speed is also high. If the detected noise level of the range hood exceeds a preset value, the infrared fume recognition module is activated to monitor the fume level of the range hood. Therefore, by monitoring the fume level through the infrared fume recognition module, the range hood can be controlled based on the amount of fume, avoiding the impact of excessive noise and ensuring timely fume removal.

[0032] In this embodiment of the invention, the monitoring of the smoke value of cooking fumes is not limited to the infrared cooking fume recognition module; other methods can also be used to monitor cooking fumes.

[0033] In one embodiment of the present invention, if the detected noise value is greater than a preset value, the user can be reminded of the noise level, and the user can check the flue condition based on the noise level.

[0034] S120: If the detected smoke value is greater than the set smoke threshold, control the range hood to continue operating in constant airflow mode.

[0035] In this embodiment of the invention, if the detected smoke level is greater than a set smoke threshold, the range hood continues to operate in constant airflow mode. That is, even when there is a large amount of smoke, the range hood continues to operate in constant airflow mode to ensure timely exhaust of the smoke. The infrared smoke recognition module monitors the smoke situation in real time, and when the detected smoke level is less than a preset value, it controls the range hood's speed to operate at a set speed.

[0036] S130: If the detected smoke value is less than the set smoke threshold, control the range hood to exit the constant air volume mode and reduce the speed of the range hood to the set speed based on the monitored environmental information.

[0037] In this embodiment of the invention, if the detected smoke value is less than the set smoke threshold, it indicates that the smoke is small, and the constant air volume mode can be exited. The speed of the range hood can be reduced to the set speed based on the monitored environmental information.

[0038] In this embodiment of the invention, the monitored environmental information can be either the environmental information within the kitchen or the monitored environmental noise. The noise requirements differ depending on the environmental information. In cases of low smoke levels, to ensure timely smoke removal and for practical needs, environmental information can be monitored, and the rotation speed of the range hood can be controlled based on the monitored environmental information.

[0039] The technical solution provided by this invention, during the operation of a range hood in constant airflow mode, if the noise level of the range hood is detected to be greater than a preset value, the smoke level of the oil fumes is monitored via an infrared smoke identification module. If the detected smoke level is greater than a set smoke threshold, the range hood is controlled to continue operating in constant airflow mode; if the detected smoke level is less than the set smoke threshold, the range hood is controlled to exit constant airflow mode, and the speed of the range hood is reduced to a set speed based on the monitored environmental information. In other words, when the range hood is operating in constant airflow mode, if the noise level of the range hood is greater than a preset value, the smoke level of the oil fumes is monitored. If the detected smoke level is greater than a set smoke threshold, the range hood is controlled to operate in constant airflow mode. This ensures that the oil fumes in the kitchen are discharged in a timely manner; if the detected smoke level is less than the set smoke threshold, the oil fumes can be discharged in a timely manner even when there is less oil fumes. This saves power consumption and allows for the control of the range hood's speed according to different environmental needs, meeting actual conditions while ensuring timely oil fume discharge and increasing practicality.

[0040] Figure 2 This is a flowchart of a range hood control method provided by an embodiment of the present invention. In this embodiment, optionally, the step of reducing the speed of the range hood to a set speed based on monitored environmental information includes:

[0041] If it is detected that the window in the kitchen is open, reduce the speed of the range hood to the first speed.

[0042] If the kitchen window is detected to be closed, the speed of the range hood is reduced to a second speed; wherein the first speed is less than the second speed.

[0043] like Figure 2 As shown, the technical solution provided by the embodiments of the present invention includes:

[0044] S210: When the range hood is operating in constant airflow mode, if the noise level of the range hood is detected to be greater than the preset value, the smoke level of the oil fume will be monitored through the infrared oil fume identification module.

[0045] S220: Determine whether the detected smoke value is greater than the set smoke threshold.

[0046] If yes, execute S230; otherwise, execute S240.

[0047] S230: Control the range hood to continue operating in constant airflow mode.

[0048] S240: Control the range hood to exit the constant air volume mode.

[0049] S250: Determine whether the window in the kitchen is open.

[0050] If yes, execute S260; otherwise, execute S270.

[0051] In this embodiment of the invention, when the kitchen window is open, the kitchen fumes can also be exhausted through the window. When the kitchen window is closed, the kitchen fumes can only be exhausted through the range hood. Therefore, when the smoke level is detected to be less than the set smoke threshold, in order to reduce noise and save energy, the speed of the range hood can be controlled by monitoring the state of the kitchen window. This can ensure the timely exhaust of fumes and can also control the range hood according to actual needs.

[0052] S260: Reduce the speed of the range hood to the first speed.

[0053] In this embodiment of the invention, when the kitchen window is open, the kitchen fumes can be exhausted through the window, which can reduce the speed of the range hood to a lower first speed, thereby reducing noise, saving energy, and allowing the fumes to be exhausted outdoors in a timely manner.

[0054] S270: Reduce the rotation speed of the range hood to a second rotation speed; wherein the first rotation speed is less than the second rotation speed.

[0055] In this embodiment of the invention, if the kitchen window is closed, the kitchen fumes can only be exhausted to the outside through the range hood. The speed of the range hood can be reduced from the constant air volume mode to a second speed, which is greater than the first speed, to ensure that the fumes are exhausted to the outside in a timely manner.

[0056] Therefore, by monitoring the status of the windows in the kitchen, when the window is detected to be open, the speed of the range hood is reduced to the first speed, and when the window is detected to be closed, the speed of the range hood is reduced to the second speed. The first speed is lower than the second speed, which can ensure that the fumes are discharged outdoors in time, and also reduce power consumption and noise.

[0057] In one embodiment of the present invention, optionally, reducing the speed of the range hood to a set speed based on monitored environmental information includes: if the distance between the open window in the kitchen and the range hood is greater than a set distance, reducing the speed of the range hood to a fifth speed; if the distance between the open window in the kitchen and the range hood is less than the set distance, reducing the speed of the range hood to a sixth speed; wherein the fifth speed is less than the sixth speed. The distance between the open window in the kitchen and the range hood can also affect the exhaust of fumes. When the distance between the open window and the range hood is close, the window is more likely to exhaust fumes. To reduce the noise of the range hood, the speed can be reduced to a lower fifth speed. When the distance between the open window and the range hood is far, the window is less likely to exhaust fumes, or the amount of fumes exhausted will be less. To ensure timely exhaust of fumes, the speed of the range hood can be reduced to a higher sixth speed, thereby ensuring that the fumes are promptly exhausted outdoors.

[0058] Figure 3 This is a flowchart of a range hood control method provided by an embodiment of the present invention. In this embodiment, optionally, the step of reducing the speed of the range hood to a set speed based on monitored environmental information includes:

[0059] If the detected noise includes ambient noise, the speed of the range hood will be reduced to the third speed.

[0060] If the detected noise does not include environmental noise, the speed of the range hood will be reduced to a fourth speed; wherein the third speed is greater than the fourth speed.

[0061] like Figure 3 As shown, the technical solution provided by the embodiments of the present invention includes:

[0062] S310: When the range hood is operating in constant airflow mode, if the noise level of the range hood is detected to be greater than the preset value, the smoke level of the oil fume will be monitored through the infrared oil fume identification module.

[0063] S320: Determine whether the detected smoke value is greater than the set smoke threshold.

[0064] If yes, proceed to S330. If no, proceed to S340.

[0065] S330: Control the range hood to continue operating in constant airflow mode.

[0066] S340: Control the range hood to exit the constant airflow mode.

[0067] S350: Determine whether the detected noise includes ambient noise.

[0068] In this embodiment of the invention, if the detected noise includes environmental noise, which can interfere with the user, it is necessary to weigh the impact of environmental noise and the noise generated by the range hood. In order to ensure that the fumes are discharged outdoors in a timely manner, the speed of the range hood can be controlled according to the noise situation.

[0069] If yes, execute S360; otherwise, execute S370.

[0070] S360: Reduce the speed of the range hood to the third speed.

[0071] In this embodiment of the invention, if the detected smoke level is less than a set smoke threshold, but the detected noise includes ambient noise, reducing the range hood's speed to a lower speed may not prevent noise interference to the user, and the fumes may not be discharged in a timely manner. Therefore, to ensure that the fumes are discharged into the room in a timely manner, the range hood's speed can be reduced to a higher third speed to guarantee timely fume discharge.

[0072] S370: Reduce the rotation speed of the range hood to a fourth rotation speed; wherein the third rotation speed is greater than the fourth rotation speed.

[0073] In this embodiment of the invention, if the detected smoke value is less than the set smoke threshold and the detected noise does not include environmental noise, in order to avoid noise interference, the speed of the range hood can be reduced from the constant air volume speed to the fourth speed, wherein the fourth speed is less than the third speed.

[0074] Therefore, by monitoring whether the noise includes environmental noise, the range hood speed is reduced to the third speed when environmental noise is included, and reduced to the fourth speed when environmental noise is not included. The third speed is greater than the fourth speed, which can avoid noise while also exhausting the fumes outdoors. The speed can be controlled according to the actual environmental conditions, making it more practical.

[0075] Figure 4 This is a flowchart of a range hood control method provided by an embodiment of the present invention. In this embodiment, optionally, the step of reducing the speed of the range hood to a set speed based on monitored environmental information includes:

[0076] If an elderly person or a child is detected in the kitchen, the speed of the range hood will be reduced to the seventh speed.

[0077] If no elderly person or child is detected in the kitchen, the speed of the range hood will be reduced to the eighth speed; wherein the seventh speed is lower than the eighth speed.

[0078] like Figure 4 As shown, the technical solution provided by the embodiments of the present invention includes:

[0079] S410: When the range hood is operating in constant airflow mode, if the noise level of the range hood is detected to be greater than the preset value, the smoke level of the oil fume will be monitored through the infrared oil fume identification module.

[0080] S420: Determine whether the detected smoke value is greater than the set smoke threshold.

[0081] If yes, execute S430; otherwise, execute S440.

[0082] S430: Control the range hood to continue operating in constant airflow mode.

[0083] S440: Control the range hood to exit the constant airflow mode.

[0084] S450: Monitors whether there are elderly people or children in the kitchen.

[0085] In this embodiment of the invention, an image can be captured by a camera, and the presence of elderly people or children in the kitchen can be identified through the image. Generally, elderly people or children are more sensitive to noise. Therefore, the presence of elderly people or children in the kitchen can be monitored, thereby controlling the speed of the range hood when the smoke level is less than the set smoke threshold.

[0086] If yes, proceed to S460; otherwise, proceed to S470.

[0087] S460: Reduce the speed of the range hood to the seventh speed.

[0088] In this embodiment of the invention, if the detected smoke value is less than the set smoke threshold, and if an elderly person or a child is detected in the kitchen, the speed of the range hood is reduced to a lower seventh speed to avoid noise causing a significant impact on the special population, and without affecting the exhaust of oil fumes.

[0089] S470: Reduce the speed of the range hood to the eighth speed, wherein the seventh speed is less than the eighth speed.

[0090] In this embodiment of the invention, if the detected smoke value is less than the set smoke threshold and no elderly person or child is detected in the kitchen, the speed of the range hood can be reduced to a higher eighth speed to expel the fumes in a timely manner.

[0091] Therefore, if the detected smoke level is less than the set smoke threshold, the range hood speed can be reduced to the seventh speed if the presence of elderly people or children is detected in the kitchen; otherwise, it can be reduced to the eighth speed. This avoids noise interference to special groups and does not affect the exhaust of fumes.

[0092] Figure 5This is a flowchart of a range hood control method provided in an embodiment of the present invention. In this embodiment, optionally, the method may further include:

[0093] If the detected smoke value is greater than the set smoke threshold, the blowing device is controlled to blow air onto the infrared smoke recognition module.

[0094] like Figure 5 As shown, the technical solution provided by the embodiments of the present invention includes:

[0095] S510: When the range hood is operating in constant airflow mode, if the noise level of the range hood is detected to be greater than the preset value, the smoke level of the oil fume will be monitored through the infrared oil fume identification module.

[0096] S520: If the detected smoke value is greater than the set smoke threshold, control the range hood to continue operating in constant airflow mode, and control the blowing device to blow air onto the infrared smoke recognition module.

[0097] In this embodiment of the invention, if the detected smoke value exceeds a set smoke threshold, the fumes may contain a large amount of oil and other particles. These oil and other particles easily adhere to the infrared fume recognition module, potentially affecting it. Therefore, when the detected smoke value exceeds the set smoke value, a blower can be controlled to blow air onto the infrared fume recognition module to prevent oil and other particles from adhering to it and keep the module clean. The position of the blower can be set as needed.

[0098] Therefore, if the detected smoke value is greater than the set smoke threshold, the blowing device is controlled to blow air onto the infrared smoke recognition module, which can prevent oil and other particles from adhering to the infrared smoke recognition module, keep the module clean, and thus ensure the accurate monitoring of the module.

[0099] S530: If the detected smoke value is less than the set smoke threshold, control the range hood to exit the constant air volume mode and reduce the speed of the range hood to the set speed based on the monitored environmental information.
