[0059] Figure 4 This is a schematic diagram of the fixed installation structure provided in Embodiment 1 of the present invention.
[0060] Reference Figure 2 and Figure 4The vibration adjustment system of the range hood also includes a fixed installation structure 4; the fixed installation structure 4 is set on the inner wall of the housing 5 and at the bottom of the fan 3 away from the air outlet 7, the fixed installation structure 4 is connected to the volute 6 and the housing 5.
[0061] The fixed installation structure 4 is set on the side of the volute 6.
[0062] The fixed installation structure 4 is used to support the fan 3 and absorb the vibration of the fan 3.
[0063] In one embodiment, reference is made to Figure 2 and Figure 4 The fixed installation structure 4 includes a second damping spring 42 and a bracket structure 41, a damping material 43 and a T-shaped bracket 44 connected in sequence; the bracket structure 41 is connected to the housing 5 through the second damping spring 42; the bracket structure 41 is connected to the volute 6; one end of the T-shaped bracket 44 is connected to the volute 6 and the other end of the T-shaped bracket 44 is connected to the housing 5.

[0069] Example 2:
[0070] Figure 5This is a flowchart of the vibration adjustment method for a range hood provided in Embodiment 2 of the present invention.
[0071] Reference Figure 5 The method for regulating the vibration of a smoke hood, applied to the aforementioned smoke hood vibration regulation system, includes:
[0072] Step S101: The vibration sensor acquires the vibration signal generated during the operation of the fan, converts the vibration signal into an electrical signal, and sends the electrical signal to the control center.
[0073] In step S102, the control center controls the vibration reduction module to reduce the vibration of the fan according to the electrical signal.
[0074] Here, the vibration signal is acquired by vibration sensor 2 in the flue gas machine vibration system.
[0075] Figure 6 This is a flowchart of the steps for the control center to reduce the vibration of the fan, as provided in Embodiment 2 of the present invention.
[0076] Reference Figure 6 The control center controls the vibration reduction module 1 to reduce the vibration of the fan according to the electrical signal, including the following steps:
[0077] Step S201: Obtain the threshold data pre-calculated by the control center; wherein, the threshold data includes threshold ranges and corresponding multiple current levels.
[0078] In one embodiment, reference is made to Figure 7 Step S201 includes:
[0079] Step S301: Obtain the real-time operating speed and the sensitivity, floor level and operating gear input by the user.
[0080] Step S302: Generate a threshold range based on sensitivity, floor level, operating gear, and real-time operating speed.
[0081] Step S303: Determine the current range corresponding to the threshold range according to the preset current range rule; wherein, the preset current range rule is that a preset number of current ranges are set in the current range.
[0082] Specifically, the sensitivity is a pre-set index of the user's sensitivity to noise, which can be divided into 1-10 levels (1 being the most sensitive, 10 being the least sensitive, and 5 being the normal level). Users can choose the appropriate level to input according to their actual situation.
[0083] The floor number refers to the actual floor number where the user lives. The lower the floor, the greater the resistance and the stronger the vibration of the fan 3 during operation.
[0084] The operating mode is the range hood operating mode selected by the user, which can be divided into low mode, high mode, and stir-fry mode, etc.
[0085] Each operating gear corresponds to a certain operating speed. However, in actual operation, due to factors such as the number of floors and users, the actual operating speed of fan 3 may have errors. Therefore, it is necessary to obtain the actual operating speed of fan 3 to obtain a more accurate threshold range.
[0086] The threshold range is a current range.
[0087] Specifically, the calculation formulas for the threshold interval are shown in formulas (1) to (3) below:
[0088]
[0089]
[0090] I 阈 =[I 阈弱 , I 阈爆 (3)
[0091] Where n is the rotational speed, and n 实 n represents the actual operating speed. k=2.1 These are commonly used fitting values in the laboratory. L represents the number of floors. 总 The total number of floors, to be filled in by the user, L 实 For the floor number, the user should enter the actual floor number. 总 γ represents the total number of sensitivities. 实 For sensitivity, the user should enter their actual sensitivity value. α and β are coefficients, typically α is between 0.5 and 0.6, and β is between 0.15 and 0.2. 阈 The threshold interval is a set of I. 阈弱 and I 阈强 The scope of the composition, I 弱 I is the preset current value for fan 3 in low speed mode. 爆炒 I is the preset current value for fan 3 in the stir-fry mode. 阈弱 This is the current value corresponding to the current speed in the low gear, which is the minimum value of the threshold range, I. 阈爆 This is the current value corresponding to the current speed at the stir-fry setting, which is the maximum value of the threshold range.
[0092] The current range corresponding to the threshold range is determined according to preset current range rules; wherein, the preset current range rules are that a preset number of current ranges are set in the current range. Here, the preset number can be set according to actual conditions, and the preset number is at least 1. That is, the number of current ranges in the current range is fixed, and there is at least one current range.
[0093] The formula for calculating the current difference corresponding to each current level is shown in formula (4):
[0094] I N =(I 阈爆 -I 阈弱 ) / N (4)
[0095] Among them, I N The current difference corresponding to each current level, where N is a preset quantity.
[0096] The difference between the maximum and minimum values of the threshold interval is divided by a preset number to obtain the current difference for each current level. Based on this current difference, the threshold interval is divided into a preset number of smaller threshold intervals, and each smaller threshold interval corresponds to a current level according to preset current level rules. For example, when N is 5, each smaller threshold interval is assigned a current level in ascending order, with the smaller threshold interval having the smallest current value corresponding to level 1, and the smaller threshold interval having the largest current value corresponding to level 5.
[0097] Step S202: Compare the electrical signal with the threshold range, and generate a current signal based on the comparison result.
[0098] In one embodiment, reference is made to Figure 8 Step S202 includes:
[0099] Step S401: When the electrical signal is within the threshold range, determine the current level corresponding to the electrical signal and generate a first current signal based on the current level.
[0100] Here, when the electrical signal is within the threshold range, it indicates that the current smoke machine vibration adjustment system is operating normally, and the first current signal can be generated according to the current level corresponding to the electrical signal.
[0101] Step S402: When the electrical signal is not within the threshold range, determine whether the real-time operating speed of the fan is within the preset speed range.
[0102] Here, the preset speed range is between the preset minimum speed and the preset maximum speed. Both the preset minimum speed and the preset maximum speed can be set according to the actual situation.
[0103] Step S403: When the real-time operating speed is greater than the preset speed range, a corresponding second current signal is generated according to the preset maximum current level corresponding to the preset maximum speed value.
[0104] Step S404: When the real-time operating speed is less than the preset speed range, generate the corresponding third current signal according to the preset minimum current level corresponding to the preset minimum speed value.
[0105] Here, when the preset minimum current level is 1, the preset maximum current level is N; when the preset minimum current level is N, the preset maximum current level is 1.
[0106] Step S405: When the real-time operating speed is within the preset speed range, a corresponding fourth current signal is generated according to the preset intermediate current level.
[0107] Here, the current signal is one of the first current signal, the second current signal, the third current signal, and the fourth current signal.
[0108] The preset intermediate current setting can be either the preset minimum current setting or the preset maximum current setting, and can be set according to the actual situation.
[0109] In step S203, the control center control power board generates an operating current based on the current signal, so that the electromagnetic material layer of the vibration damping module generates a corresponding magnetic force based on the operating current.
[0110] In step S204, the first damping spring of the damping module generates a corresponding relaxation degree according to the magnetic force of the electromagnetic material layer to reduce the vibration of the fan; wherein, the magnitude of the magnetic force of the electromagnetic material layer is proportional to the relaxation degree of the first damping spring.
[0111] Specifically, refer to Figure 9 After the fan 3 is turned on, the vibration sensor 2 acquires the vibration signal of the fan 3, converts the vibration signal into an electrical signal and sends it to the control center.
[0112] The control center compares the electrical signal with the threshold range.
[0113] If the electrical signal is within the threshold range, the corresponding first current signal is determined based on the correspondence between the threshold range and the current positioning range. The control center control power board generates a first operating current based on the first current signal. The power board sends the first operating current to the electromagnetic material layer 13, thereby changing the magnetic strength of the electromagnetic material layer 13, and thus changing the relaxation of the first damping spring 11.
[0114] Specifically, the larger the operating current, the stronger the magnetism of the electromagnetic material layer 13, the greater the relaxation of the first damping spring 11, and the closer the first damping spring 11 is to a semi-flexible state. Conversely, the smaller the operating current, the weaker the magnetism of the electromagnetic material layer 13, the smaller the relaxation of the first damping spring 11, and the closer the first damping spring 11 is to an elastic state. Here, the semi-flexible state of the first damping spring 11 provides better damping than the elastic state.
[0115] If the electrical signal is outside the threshold range, the real-time operating speed is compared with the preset maximum and minimum speed values. When the real-time operating speed is greater than the preset maximum speed, a corresponding second current signal is generated based on the preset maximum current level corresponding to the preset maximum speed. The control power board of the control center generates a second operating current based on the second current signal, and sends the second operating current to the electromagnetic material layer 13 to maximize the magnetism of the electromagnetic material layer 13, thereby maximizing the relaxation of the first damping spring 11, so as to maximize the operating efficiency of the damping module 1 and achieve the best damping effect on the fan.
[0116] When the real-time operating speed is less than the preset minimum speed, a corresponding third current signal is generated based on the preset minimum current level corresponding to the preset minimum speed. The control center control power board generates a third operating current based on the third current signal, and sends the third operating current to the electromagnetic material layer 13 to minimize the magnetism of the electromagnetic material layer 13, thereby minimizing the relaxation of the first damping spring 11.
[0117] Here, if the electrical signal is outside the threshold range and the real-time operating speed is between the preset maximum and minimum speed values, it indicates a malfunction in the range hood. After displaying "Operating Error" on the range hood control panel, a corresponding fourth current signal is generated based on the preset intermediate current setting. The control center's power board generates a fourth operating current based on this signal and sends it to the electromagnetic material layer 13 to ensure the vibration damping module 1 operates at the intermediate setting. Simultaneously, relevant malfunction information is synchronized to the backend, and relevant personnel will provide on-site service based on the fault information.
[0118] This invention provides a method for regulating the vibration of a range hood, including a housing, a fan, a vibration damping module, and a vibration sensor. The vibration damping module and the vibration sensor are respectively connected to a control center within the fan. Both the fan and the vibration damping module are located inside the housing, with the vibration damping module positioned at the top of the housing and connected to both the fan and the housing. The vibration sensor acquires vibration signals generated by the fan during operation, converts these signals into electrical signals, and sends them to the control center. The control center controls the vibration damping module to dampen the fan based on the electrical signals. In this method, by installing a vibration sensor on the fan and a vibration damping module between the fan and the housing, the vibration damping module can automatically adjust the vibration transmission between the fan and the housing based on the vibration signals received by the vibration sensor, thereby reducing the vibration generated during fan operation and consequently reducing noise generation.
