[0061] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0062] Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the invention. It should be understood that the accompanying drawings and embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the invention.

[0063] With the popularization of smart home appliances, range hoods are also developing towards intelligence. Since the main function of range hoods is to remove the oil fumes generated in the kitchen, a large amount of oil stains accumulate inside the range hood, which seriously affects the operating efficiency of the range hood. Therefore, how to efficiently clean the oil stains of range hoods has become an important research topic for range hoods.

[0064] In existing technology, users judge the amount of grease inside the range hood based on experience, then trigger a grease cleaning command. The range hood cleans the grease according to the grease cleaning command, and finally, the user judges based on experience that the grease has been cleaned and triggers a grease cleaning stop command.

[0065] However, existing technology can only control the range hood to clean grease based on user experience, and cannot automatically determine whether the range hood needs to be cleaned and how long it will take to clean it. This not only results in low cleaning efficiency of the range hood, but also wastes electricity.

[0066] To address these issues, the inventors discovered that when a large amount of grease adheres to the volute and impeller of a range hood, the motor load increases. To maintain the same rotational speed, the motor needs to increase its operating power. Therefore, by monitoring changes in motor power, the degree of grease buildup can be determined, thus indicating whether cleaning of the range hood is necessary. Furthermore, the required heating time for cleaning can be determined based on the motor's operating power at a preset speed. Thus, by monitoring the increase in motor power at a preset speed, the need for cleaning and the required cleaning time can be determined, enabling automatic cleaning of the range hood, thereby improving cleaning efficiency and saving energy.

[0067] The oil stain cleaning method for range hoods provided in this application embodiment can be executed by the oil stain cleaning device for range hoods provided in this application embodiment. The oil stain cleaning device for range hoods provided in this application embodiment can be part of the range hood. Figure 1 This is a schematic diagram of a scenario architecture upon which this disclosure is based, such as... Figure 1 As shown, the scenario architecture based on this disclosure may include a range hood oil stain cleaning device 1, a heating device 2, and a range hood 3. The range hood oil stain cleaning device 1 is hardware or software installed in the range hood 3, which can be used to perform the range hood oil stain cleaning method described in the following embodiments.

[0068] When the range hood oil stain cleaning device 1 is hardware, it can be an electronic device with computing functions; when the range hood oil stain cleaning device 1 is software, it can be installed in an electronic device with computing functions, including but not limited to a control board, etc.

[0069] Specifically, in the first scenario, the range hood grease cleaning device 1 is a control board with a control program written into it. The control board is connected to and communicates with the main board of the range hood to control the motor and heating device. In the second scenario, the range hood grease cleaning device 1 is a control program written into the main board of the range hood and runs on the existing main board to control the motor and heating device.

[0070] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0071] Figure 2 This is a flowchart illustrating a method for cleaning grease from a range hood, as provided in this embodiment. The method is applicable to range hoods, which include a motor, a volute housing the motor, and a heating device mounted on the outer wall of the volute housing. Figure 2 As shown in the embodiments of this application, the method for cleaning oil stains on a range hood may include:

[0072] S21. Control the motor to run at a preset speed and monitor the current operating power of the motor;

[0073] In this embodiment, when the impeller and motor shaft are contaminated with oil, the motor load will increase, and in order to maintain the same speed, the motor needs to increase its operating power.

[0074] In other words, monitoring the motor's operating power at the same speed can reflect changes in the motor's load, thereby determining the degree of oil contamination on the motor based on its operating power.

[0075] In one possible implementation, controlling the motor to operate at a preset speed and monitoring the current operating power of the motor includes: triggering the self-cleaning program of the range hood; controlling the motor to operate at a preset speed according to the self-cleaning program and monitoring the current operating power of the motor.

[0076] It should be noted that for a range hood to perform self-cleaning, its self-cleaning program needs to be triggered, and there is more than one way to trigger this program.

[0077] Furthermore, triggering the range hood's self-cleaning program includes: triggering the range hood's self-cleaning program if the total running time of the range hood reaches a preset time threshold; and / or, triggering the range hood's self-cleaning program if a user sends a start command for the self-cleaning program.

[0078] In other words, the range hood's self-cleaning program can be triggered automatically based on its total operating time, or it can be triggered by receiving a start command from the user. There are no restrictions on this.

[0079] For example, in the first scenario, the range hood cleaning device detects that the range hood has been running for 24 hours, reaching the preset time threshold of 24 hours, triggering the range hood's self-cleaning program. This controls the range hood motor to run at a preset speed of 40 r / s, and monitors that the current operating power of the range hood motor at the preset speed is 190W. In the second scenario, the range hood cleaning device 1 receives a self-cleaning command sent by the user via a smartphone, triggering the range hood's self-cleaning program. This controls the range hood motor to run at a preset speed of 40 r / s, and monitors that the current operating power of the range hood motor at the preset speed is 190W.

[0080] S22. Based on the current operating power and preset operating power of the motor, control the heating device to heat the volute.

[0081] In this embodiment, the motor load increases when a large amount of oil stains adhere to the volute and impeller of the range hood. This increased motor load affects the current operating power of the motor. Therefore, the change in the current operating power relative to the preset operating power can reflect the degree of oil stain contamination, thereby determining whether the volute needs to be heated to remove the oil stains.

[0082] In other words, the oil contamination coefficient can be determined based on the operating power of the range hood after it becomes contaminated with oil and the operating power before it becomes contaminated with oil. Based on the oil contamination coefficient, it can be determined whether to control the heating device to heat the volute.

[0083] It should be noted that the preset operating power is the operating power of the motor when it first runs at the preset speed.

[0084] In one possible implementation, controlling the heating device to heat the volute based on the current operating power and the preset operating power of the motor includes: determining an oil contamination coefficient, wherein the oil contamination coefficient is the ratio of the current operating power to the preset operating power; and determining whether to control the heating device to heat the volute based on the oil contamination coefficient.

[0085] For example, if the operating power of the range hood motor is 160W when it first starts at a preset speed of 40r / s, then the preset operating power is 160W. If the current operating power of the range hood motor at the preset speed of 40r / s is monitored to be 170W, the ratio of the current operating power of 170W to the preset operating power of 160W is calculated to obtain an oil contamination coefficient of 1.06.

[0086] After determining the oil contamination coefficient, it is possible to determine whether to control the heating device to heat the volute by judging the relationship between the oil contamination coefficient and the preset coefficient threshold. Specifically, if the oil contamination coefficient is greater than the preset coefficient threshold, the heating device is controlled to heat the volute.

[0087] In other words, if the oil stain contamination coefficient is greater than the preset threshold, it means that the range hood is heavily contaminated with oil, and the volute needs to be heated to clean the oil stains; if the oil stain contamination coefficient is less than the preset threshold, it means that the range hood is lightly contaminated with oil, and the volute does not need to be heated to clean the oil stains.

[0088] Taking the range hood mentioned above as an example, since the oil stain contamination coefficient of 1.06 is greater than the preset coefficient threshold of 1.05, the heating device is controlled to heat the volute.

[0089] If it is determined that the volute needs to be heated to clean the oil stains, the heating time of the heating device on the volute is calculated. The specific method includes: determining the motor load change rate based on the current operating power and the preset operating power; determining the heating time based on the motor load change rate and the preset oil stain dissolution time coefficient; and controlling the heating device to heat the volute according to the heating time.

[0090] Specifically, the power change value is obtained by first calculating the difference between the current operating power and the preset operating power, then the motor load change rate is obtained by calculating the ratio of the power change value to the preset operating power, and finally the heating time is obtained by multiplying the motor load change rate by the preset oil dissolution time coefficient.

[0091] It should be noted that the preset oil dissolution time coefficient was obtained through experiments and is used to represent the time required for oil dissolution under a unit load change rate of the motor.

[0092] Taking the range hood mentioned above as an example, first, the difference between the current operating power of 170W and the preset operating power of 160W is calculated to obtain a power change value of 10W. Then, the ratio of the power change value of 10W to the preset operating power of 160W is calculated to obtain a motor load change rate of 0.06. Finally, the product of the motor load change rate of 0.06 and the preset oil dissolution time coefficient of 100 is calculated to obtain a heating time of 6 minutes.

[0093] In addition, an oil cup is provided at the bottom of the volute. The oil cleaning method further includes: controlling the heating device to heat the volute to a preset temperature range so that the oil flows through the volute into the oil cup at its bottom.

[0094] It should be noted that the preset temperature range is greater than 100 degrees Celsius and less than 120 degrees Celsius, and the preset oil dissolution time coefficient is measured by heating the volute to the preset temperature range.

[0095] As can be seen, the oil stain cleaning method for range hoods provided in this embodiment, compared with the prior art, controls the motor to operate at a preset speed and monitors the current operating power of the motor; based on the current operating power and the preset operating power of the motor, the heating device is controlled to heat the volute. The solution provided in this embodiment determines whether oil stain cleaning is needed and the time required for cleaning by monitoring the operating power of the motor at the preset speed, thus achieving automatic cleaning of oil stains in the range hood. This not only improves the cleaning efficiency of the range hood but also saves energy.

[0096] In actual use, after the heating device heats the volute, it is also necessary to control the motor to run at a preset speed and monitor the current operating power of the motor to determine the cleaning effect of the oil stains.

[0097] In an optional embodiment, in Figure 2 Based on the illustrated embodiments, in order to better utilize the oil stain cleaning method for range hoods mentioned in this invention, Figure 3 A flowchart of another method for cleaning oil stains on a range hood provided in this disclosure embodiment is shown below. Figure 3 As shown, after S22, it also includes:

[0098] S23. Control the motor to run at a preset speed for a preset time, and monitor the current operating power of the motor;

[0099] In this embodiment, after heating the volute, it is necessary to determine the oil cleaning effect. Therefore, the operating power of the motor is monitored again when it is running stably at a preset speed to determine the degree of oil contamination after cleaning.

[0100] For example, the motor speed is controlled to run at 40 r / s and kept running stably for 1 minute, and the current operating power of the motor is monitored to be 165W.

[0101] S24. Return to the step of controlling the heating device to heat the volute based on the current operating power and preset operating power of the motor.

[0102] In this embodiment, the degree of oil contamination on the range hood after heating is determined based on the current operating power of the motor and the preset operating power, and it is determined whether further heating is needed. The same method as in the previous embodiment is used, and will not be repeated here.

[0103] For example, the ratio of the current operating power of 165W to the preset operating power of 160W is calculated to obtain an oil contamination coefficient of 1.03. Since the oil contamination coefficient of 1.03 is less than the preset coefficient threshold of 1.05, there is no need to control the heating device to heat the volute.

[0104] As can be seen, the oil stain cleaning method for a range hood provided in this embodiment heats the volute, controls the motor to run at a preset speed for a preset time, monitors the current operating power of the motor, and determines whether to continue cleaning the oil stains based on the current operating power, thereby achieving automatic judgment of the oil stain cleaning effect.
