[0016] See Figures 1 to 4 , Figure 1 It is a schematic structural diagram of the range hood 1000 provided by an embodiment of the present invention; Figure 2 It is a schematic structural diagram of the cleaning part 20 in the starting position provided by an embodiment of the present invention; Figure 3 It is a schematic structural diagram of the cleaning part 20 in the swinging state provided by an embodiment of the present invention; Figure 4 It is a schematic structural diagram of the cleaning part 20 provided by an embodiment of the present invention. AsFigure 1 As shown in the figure, the intelligent cleaning device 100 includes a first magnetic attraction part 10 and a cleaning part 20; the first magnetic attraction part 10 is arranged inside a structural member 200 of the range hood 1000; the cleaning part 20 is connected to the structural member 200 and is located in front of the first magnetic attraction part 10, and the cleaning part 20 is provided with a second magnetic attraction part 21; wherein, the second magnetic attraction part 21 can drive the cleaning part 20 to perform a swinging motion under the action of the first magnetic attraction part 10 to throw out the oil stains on the cleaning part 20.

[0017] Specifically, the range hood 1000 can be a device such as a range hood for sucking kitchen fumes, which can include a structural member 200 and an intelligent cleaning device 100. The structural member 200 can refer to the main structural framework of the range hood 1000, including basic hardware such as a cavity and a housing, and is used for installing devices such as a motor and a wind wheel. It can be understood that necessary devices of the range hood 1000 are installed inside the structural member 200, and the installed devices are conventional devices in this field, and their specific types are not limited here.

[0018] The intelligent cleaning device 100 can include a first magnetic attraction part 10 and a cleaning part 20. The first magnetic attraction part 10 is arranged inside the structural member 200, and the first magnetic attraction part 10 is electrically connected to a controller and can be controlled by the controller to be powered on or off. The cleaning part 20 is connected to the structural member 200 and is located in front of the first magnetic attraction part 10. A second magnetic attraction part 21 is arranged inside the cleaning part 20, and the second magnetic attraction part 21 is also electrically connected to the controller and can be controlled by the controller to be powered on or off. When the cleaning part 20 is connected to the structural member 200, it can be connected through a connecting member such as a rotating shaft, which is convenient for swinging with the rotating shaft as a fulcrum.

[0019] The cleaning part 20 can specifically be a baffle plate. One of its main functions is to prevent the oil stains entering the range hood 1000 from adhering to the structural member 200, so that the oil stains adhere to the cleaning part 20. Another main function is to throw out the oil stains on the cleaning part 20 to complete the cleaning.

[0020] During actual use, if cleaning is required, the controller can power on the first magnetic attraction part 10 and the second magnetic attraction part 21. After being powered on, the first magnetic attraction part 10 and the second magnetic attraction part 21 generate mutually repulsive magnetic fields. Under the action of the repulsive force of the first magnetic attraction part 10, the second magnetic attraction part 21 drives the cleaning part 20 to move away from the first magnetic attraction part 10. When the cleaning part 20 swings to the highest point, the cleaning part 20 returns to the starting position under the action of gravity and then returns to the highest point again by the repulsive force of the first magnetic attraction part 10, thereby forming a swinging motion. Under the action of the swinging motion, the oil stains on the cleaning part 20 can be thrown out, thereby completing the cleaning of the cleaning part 20.

[0021] As Figure 2 shown, Figure 2FIG. 0 is a schematic structural diagram when the cleaning unit 20 is in the starting position. At this time, the cleaning unit 20 is parallel to the first magnetic attraction unit 10. When the controller controls the first magnetic attraction unit 10 and the second magnetic attraction unit 21 to be energized, a mutually repulsive magnetic field is generated between the first magnetic attraction unit 10 and the second magnetic attraction unit 21. Under the action of the repulsive force of the first magnetic attraction unit 10, the second magnetic attraction unit 21 drives the cleaning unit 20 to move away from the first magnetic attraction unit 10, as Figure 3 shown. Figure 3 FIG. 4 is a schematic structural diagram during the swinging process of the cleaning unit 20. If Figure 3 the cleaning unit 20 in FIG. 6 is at the highest point, then at the next moment, the cleaning unit 20 will move towards the first magnetic attraction unit 10 under the action of gravity and return to the position as shown in Figure 2 FIG. 8. During a cleaning process, the cleaning unit 20 will swing several times until the oil stains on its body are completely thrown out to complete the cleaning. Thus, it is possible to clean the internal oil stains without disassembling the whole machine.

[0022] As a further embodiment, the first magnetic attraction unit 10 is a first coil, the second magnetic attraction unit 21 is a second coil, and both the first coil and the second coil are connected to the controller of the range hood 1000; wherein, the first coil and the second coil generate a mutually repulsive magnetic field under the action of the controller.

[0023] Wherein, the first magnetic attraction unit 10 is a first coil, the second magnetic attraction unit 21 is a second coil. The first magnetic attraction unit 10 can be embedded in the structural member 200, the second magnetic attraction unit 21 can be embedded in the cleaning unit 20, and both the first coil and the second coil are electrically connected to the controller and can be energized under the control of the controller, thereby generating a mutually repulsive magnetic field.

[0024] As a further embodiment, the cleaning unit 20 is connected to the structural member 200 through a rotating member 30.

[0025] Wherein, the rotating member 30 can be a rotating shaft for connecting the cleaning unit 20 and the structural member 200, facilitating the swinging of the cleaning unit 20 along the rotating shaft.

[0026] Referring to Figure 5 , the present invention also provides a control method, which is used to control the intelligent cleaning device described in any one of the above embodiments, and the control method includes S110 - S130.

[0027] S110, driven by a cleaning instruction for cleaning the range hood, drives the cleaning unit to perform a swinging motion.

[0028] In an embodiment of the present invention, when a user needs to clean the oil stains inside the range hood, a cleaning instruction can be triggered through the control panel of the range hood. When the range hood receives the cleaning instruction, it controls the intelligent cleaning device to perform cleaning.

[0029] During cleaning, the controller first energizes the first magnetic attraction part and the second magnetic attraction part, so that the first magnetic attraction part and the second magnetic attraction part generate a mutually repulsive magnetic field. The second magnetic attraction part drives the cleaning part to move under the action of the repulsive force of the first magnetic attraction part. When the cleaning part moves to the highest point, the cleaning part returns to the starting position under the action of gravity, thereby forming a swinging motion, and the oil stains on the cleaning part are thrown out through the swinging motion.

[0030] S120, record the time when the cleaning part starts from the starting position and returns to the starting position again during the swinging motion to obtain the target time.

[0031] In an embodiment of the present invention, the cleaning part starting from the starting position and returning to the starting position again is recorded as one swing, and the time experienced in this process is recorded to obtain the target time. As Figure 2 and Figure 3 shown, Figure 2 is a schematic structural diagram when the cleaning part is at the starting position, Figure 3 is a schematic structural diagram when the cleaning part is in a swinging motion. If Figure 3 the position where the cleaning part is located is the highest point, then at the next moment, the cleaning part moves towards the first magnetic attraction part under the action of gravity and returns to the starting position. This process is recorded as one swing, and the time experienced in this process is recorded as the target time.

[0032] The method for obtaining the target time can be measured by an object detection sensor. For example, timing starts when the cleaning part is detected to disappear, and timing ends when the cleaning part is detected again. It can also be measured by detecting the capacitance change between the first magnetic attraction part and the second magnetic attraction part.

[0033] S130, if the target time is the same as the preset reference time, it is confirmed that the cleaning of the cleaning part is completed.

[0034] In an embodiment of the present invention, the preset reference time is the time experienced by the cleaning part to complete one swing movement in the cleaning state. The cleaning state means that there is no oil stain on the cleaning part, which can be measured when the range hood runs for the first time. Specifically, when the cleaning part is in a state without oil stain, record the time required for the cleaning part to complete one swing as the preset reference time. Denote the time required for the cleaning part to complete one swing when it is in a state without oil stain as T1, and the time required for the cleaning part to complete one swing when it has an oil stain as T2. Then T2 is usually less than T1. As the oil stain state on the cleaning part becomes more serious, the value of T2 will be smaller. That is, the more oil stains there are on the cleaning part, the less time it takes for the cleaning part to complete one swing.

[0035] When the target time is the same as the preset reference time, it indicates that the oil stain on the cleaning part has been completely thrown out, and this cleaning can be ended. It can be understood that in addition to the target time being the same as the preset reference time being regarded as the oil stain being completely thrown out, a certain redundancy can also be set. For example, when the difference between the target time and the preset reference time is within 1%, the oil stain can be regarded as being completely thrown out.

[0036] See Figure 6 , in some embodiments, such as in the embodiment of the present invention, step S140 of the control method.

[0037] S140, if the target time is less than the preset reference time, continue to drive the cleaning part to perform a swing movement until the target time is the same as the preset reference time.

[0038] In the embodiment of the present invention, when the target time is less than the preset reference time, it indicates that there is still oil stain on the cleaning part, and the swing state of the cleaning part can be maintained until the oil stain is completely thrown out.

[0039] See Figure 7 , in some embodiments, such as in the embodiment of the present invention, step S150 of the control method.

[0040] S150, if the number of swings of the cleaning part reaches the preset number of times, control the cleaning part to stop the swing movement, and heat the second magnetic attraction part of the cleaning part to heat the temperature of the second magnetic attraction part to the preset temperature.

[0041] In the embodiment of the present invention, the preset number of times is an empirical value, which can be adapted according to different types of range hoods. When the number of swings reaches the preset number of times, the cleaning part can be controlled to stop swinging, and then the controller continuously passes a low current to the second magnetic attraction part to make the second magnetic attraction part heat up until the temperature of the second magnetic attraction part is heated to the preset temperature, for example, heated to 60 °C, so as to soften the solidified oil stain on the cleaning part. It can be understood that the preset temperature is an empirical value, usually the temperature at which the solidified oil stain is easily melted.

[0042] See Figure 8 , in some embodiments, such as in the embodiments of the present invention, the control method steps S160 - S161.

[0043] S160, detect the temperature of the second magnetic attraction part in real time to obtain the target temperature; S161, if the target temperature reaches the preset temperature, drive the cleaning part to perform a swinging motion until the target time is the same as the preset reference time.

[0044] In the embodiments of the present invention, when the second magnetic attraction part is in a heating state, the temperature of the second magnetic attraction part can be detected in real time to obtain the target temperature, and when the target temperature reaches the preset temperature, the heating is stopped, and the cleaning part is driven to swing until the target time required for the cleaning part to complete one swing is the same as the preset reference time. Additionally, when the target temperature reaches the preset temperature, it can be maintained for a period of time to fully dissolve the solidified oil stains.

[0045] See Figure 9 , in some embodiments, such as in the embodiments of the present invention, the control method steps S170 - S171.

[0046] S170, if it is detected that the cleaning part starts to perform a swinging motion, monitor the capacitance between the second magnetic attraction part and the first magnetic attraction part of the cleaning part in real time to obtain the target capacitance; S171, take the time experienced from the start of change to the stop of change of the target capacitance as the time experienced for the cleaning part to complete one swing.

[0047] In the embodiments of the present invention, measuring the time experienced for the cleaning part to complete one swing can be specifically carried out by measuring the change in capacitance. When the first magnetic attraction part and the second magnetic attraction part are energized, a magnetic field will be generated between the first magnetic attraction part and the second magnetic attraction part, and then the capacitance value between the first magnetic attraction part and the second magnetic attraction part can be detected. When the cleaning part starts to move, parameters such as the distance and the facing area between the second magnetic attraction part and the first magnetic attraction part will change, resulting in a change in the capacitance value. When the cleaning part returns to the initial position, the positions of the first magnetic attraction part and the second magnetic attraction part are relatively fixed, and the capacitance value no longer changes.

[0048] Record the start time when the target capacitance starts to change. During the swinging process of the cleaning part, the target capacitance will continuously change with the swinging of the cleaning part until the cleaning part returns to the starting position. Record the time when the target capacitance no longer changes as the end time, and record the time between the start time and the end time as the time required for the cleaning part to complete one swing.

[0049] In addition, the capacitance value can also be used as a criterion for determining whether the cleaning part has completed cleaning. For example, when the cleaning part is in a state without oil stains, the minimum value of the target capacitance value is used as the reference capacitance value, and then the minimum value of the target capacitance value during the cleaning process is recorded. If the minimum value of the target capacitance value is greater than the reference capacitance value, it indicates that there is still oil stain on the cleaning part and the swinging motion can continue. If the minimum value of the target capacitance value is the same as the reference capacitance value, it indicates that all the oil stains on the cleaning part have been thrown out.

[0050] The present invention also provides an oil fume extractor, which includes a structural member and the intelligent cleaning device according to any one of the above embodiments; the intelligent cleaning device 100 includes a first magnetic attraction part 10 and a cleaning part 20; the first magnetic attraction part 10 is arranged in the structural member 200 of the oil fume extractor 1000; the cleaning part 20 is connected to the structural member 200 and is located in front of the first magnetic attraction part 10, and the cleaning part 20 is provided with a second magnetic attraction part 21; wherein, the second magnetic attraction part 21 can drive the cleaning part 20 to perform a swinging motion under the action of the first magnetic attraction part 10 to throw out the oil stains on the cleaning part 20.

[0051] Specifically, the oil fume extractor 1000 can be a device such as an oil fume extractor for sucking kitchen oil fume. It can include a structural member 200 and an intelligent cleaning device 100. The structural member 200 can refer to the main structural framework of the oil fume extractor 1000, including basic hardware such as a cavity and a housing, and is used for installing devices such as a motor and a wind wheel. It can be understood that necessary devices of the oil fume extractor 1000 are installed in the structural member 200, and the installed devices are conventional devices in the art, and their specific types are not limited here.

[0052] The intelligent cleaning device 100 can include a first magnetic attraction part 10 and a cleaning part 20. The first magnetic attraction part 10 is arranged in the structural member 200, and the first magnetic attraction part 10 is electrically connected to the controller and can be controlled by the controller to be energized or not. The cleaning part 20 is connected to the structural member 200 and is located in front of the first magnetic attraction part 10. A second magnetic attraction part 21 is arranged in the cleaning part 20, and the second magnetic attraction part 21 is also electrically connected to the controller and can be controlled by the controller to be energized or not. When the cleaning part 20 is connected to the structural member 200, it can be connected through a connecting member such as a rotating shaft, which is convenient for swinging with the rotating shaft as a fulcrum.

[0053] The cleaning part 20 can specifically be a baffle plate. One of its main functions is to prevent the oil stains entering the oil fume extractor 1000 from adhering to the structural member 200, so that the oil stains adhere to the cleaning part 20. The second main function is to throw out the oil stains on the cleaning part 20 to complete the cleaning.

[0054] During actual use, if cleaning is required, the controller can energize the first magnetic attraction part 10 and the second magnetic attraction part 21. After being energized, the first magnetic attraction part 10 and the second magnetic attraction part 21 generate mutually repulsive magnetic fields. Under the action of the repulsive force of the first magnetic attraction part 10, the second magnetic attraction part 21 drives the cleaning part 20 to move away from the first magnetic attraction part 10. When the cleaning part 20 swings to the highest point, the cleaning part 20 returns to the starting position under the action of gravity and then returns to the highest point again by the repulsive force of the first magnetic attraction part 10, thereby forming a swinging motion. Under the action of the swinging motion, the oil stains on the cleaning part 20 can be thrown out, thus completing the cleaning of the cleaning part 20.

[0055] As Figure 2 shown, Figure 2 Figure 7 is a schematic structural diagram of the cleaning part 20 at the starting position. At this time, the cleaning part 20 is parallel to the first magnetic attraction part 10. When the controller controls the first magnetic attraction part 10 and the second magnetic attraction part 21 to be energized, a mutually repulsive magnetic field is generated between the first magnetic attraction part 10 and the second magnetic attraction part 21. Under the action of the repulsive force of the first magnetic attraction part 10, the second magnetic attraction part 21 drives the cleaning part 20 to move away from the first magnetic attraction part 10, as Figure 3 shown, Figure 3 Figure 8 is a schematic structural diagram of the cleaning part 20 during the swinging process. If Figure 3 the cleaning part 20 in Figure 8 is at the highest point, then at the next moment, the cleaning part 20 will move towards the first magnetic attraction part 10 under the action of gravity and return to the position as shown in Figure 2 Figure 7. During one cleaning process, the cleaning part 20 will swing several times until the oil stains on its body are completely thrown out and the cleaning is completed. Thus, the cleaning of the internal oil stains can be completed without disassembling the whole machine.

[0056] The intelligent cleaning device, control method and range hood disclosed by the present invention can prevent oil stains from adhering to the structural parts through the cleaning part, and drive the cleaning part to perform a swinging motion through the first magnetic attraction part and the second magnetic attraction part, so as to throw out the oil stains on the cleaning part, thereby completing the cleaning of the cleaning part without disassembling the whole machine.

[0057] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention.
