Detailed Embodiments

[0037] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] As Figure 1 shown, the cleaning control method of the electrostatic oil fume purifier provided by the present invention includes: obtaining the arc warning information of the electrostatic field of the electrostatic oil fume purifier and the arcing warning information of the power supply of the electrostatic oil fume purifier, and when both the arc warning information and the arcing warning information meet the preset requirements, controlling the cleaning mechanism to perform a cleaning operation on the electrostatic oil fume purifier.

[0039] By obtaining the arc warning information of the electrostatic field of the electrostatic oil fume purifier and the arcing warning information of the power supply of the electrostatic oil fume purifier, and comprehensively judging whether the electrostatic oil fume purifier needs to be cleaned according to whether the arc warning information and the arcing warning information meet the preset requirements, it is possible to avoid untimely cleaning and frequent cleaning of the electrostatic oil fume purifier in the prior art, and prevent fire hazards and waste of resources.

[0040] Further, the step of obtaining the arc warning information of the electrostatic field of the electrostatic oil fume purifier includes: obtaining the emission time of each arc, continuously calculating the time interval between adjacent arcs, recording the arc time interval less than the preset time interval as a valid arc, and when the time intervals of a continuous preset number of arcs are all valid arcs, recording it as one piece of arc warning information; counting the number of records of the arc warning information, and when the number of records of the arc warning information exceeds the preset value of the number of arc warning information, the arc warning information meets the preset requirements.

[0041] In this embodiment, the arc generated by the electrostatic field of the electrostatic oil fume purifier can be continuously obtained through a light sensor, and the time interval between adjacent arcs is recorded. For example, the obtained arcs are recorded as the 1st arc, the 2nd arc, the 3rd arc... the Nth arc, where N is a natural number. Continuously calculating the time interval between adjacent arcs is the time interval between the 1st arc and the 2nd arc, the time interval between the 2nd arc and the 3rd arc, until the time interval between the N - 1th arc and the Nth arc, and comparing the calculated time intervals of multiple adjacent arcs with the preset time interval respectively. When it is less than the preset time interval, it is determined as a valid arc. When the number of consecutive valid arcs reaches the preset number, it is recorded as one piece of arc warning information, and the number of records of the arc warning information is counted. When the counted number of records of the arc warning information reaches the preset value, the arc warning information meets the preset requirements.

[0042] The preset time interval for determining effective arcing, the number of consecutive effective arcing times reaching the preset quantity, and the preset value of the recording times of arcing warning information can all be set manually. Those skilled in the art can set them according to actual statistical data or empirical data. Among them, the preset time interval can be 1 second, 2 seconds, 5 seconds, or 10 seconds, etc. The number of consecutive effective arcing times reaching the preset quantity and the preset value of the recording times of arcing warning information can be natural numbers, such as 1 time, 2 times, 3 times... N times, where N is a natural number.

[0043] Further, the step of obtaining the arcing warning information of the power supply of the electrostatic oil fume purifier includes: obtaining the emission time of each arcing, continuously calculating the time interval between adjacent two arcing times. When the arcing time interval is greater than the preset time interval, it is recorded as an effective arcing. When the time intervals of consecutive preset quantity of arcing times are all effective arcing, it is recorded as one arcing warning information; counting the recording times of the arcing warning information. When the recording times of the arcing warning information exceed the quantity value of the preset arcing warning information, the arcing warning information reaches the preset requirement.

[0044] Similarly, each arcing can be obtained through the intelligent high-voltage power supply of the electrostatic oil fume purifier, and the time interval between adjacent two arcing times can be recorded. For example, the obtained arcing lights are recorded as the 1st arcing, the 2nd arcing, the 3rd arcing... the Nth arcing, where N is a natural number. Continuously calculating the time interval between adjacent two arcing times is the time interval between the 1st arcing and the 2nd arcing, the time interval between the 2nd arcing and the 3rd arcing, until the time interval between the (N - 1)th arcing and the Nth arcing, and comparing the calculated time intervals of multiple adjacent two arcing times with the preset time interval respectively. When it is less than the preset time interval, it is determined as an effective arcing. When the number of consecutive effective arcing times reaches the preset quantity, it is recorded as one arcing warning information. Counting the recording times of the arcing warning information. When the recording times of the statistically obtained arcing warning information reach the preset value, the arcing warning information reaches the preset requirement.

[0045] The preset time interval for determining effective arcing, the number of consecutive effective arcing times reaching the preset quantity, and the preset value of the recording times of arcing warning information can all be set manually. Those skilled in the art can set them according to actual statistical data or empirical data. Among them, the preset time interval can be 1 second, 2 seconds, 5 seconds, or 10 seconds, etc. The number of consecutive effective arcing times reaching the preset quantity and the preset value of the recording times of arcing warning information can be natural numbers, such as 1 time, 2 times, 3 times... N times, where N is a natural number.

[0046] In this embodiment, when there is too much oil stain in the electrostatic oil fume purifier, an arc phenomenon will occur in the electrostatic field of the electrostatic electro-acoustic generator. The arc can be detected by the light sensor 100. Whenever the time interval between two detected arcs is less than 2 seconds, it is regarded as continuous discharge, and it is determined as an effective arc; when the time interval between two arcs is greater than 2 seconds, it is regarded as an accidental phenomenon and determined as an ineffective arc, and the effective arc is re-determined. When there are 10 consecutive effective arcs, the light sensor 100 emits a warning signal, and by analogy, N arc warning signals are continuously emitted, where N is a natural number.

[0047] The intelligent high-voltage power supply of the electrostatic oil fume purifier will count the number of arc strikes. When the time interval between two adjacent arc strikes is less than 3 seconds, it is regarded as continuous arc strikes and determined as effective arc strikes; when the time interval between two adjacent arc strikes is greater than 3 seconds, it is regarded as an accidental phenomenon and determined as ineffective arc strikes, and the effective arc strikes are re-determined. When there are 10 consecutive effective arc strikes, the intelligent high-voltage power supply emits an arc strike warning signal, and by analogy, N arc strike warning signals are continuously emitted, where N is a natural number.

[0048] In this embodiment, when 3 arc warning signals are emitted, the arc warning information reaches the preset requirement; when 1 arc strike warning signal is emitted, the arc strike warning information reaches the preset requirement, and the cleaning program of the cleaning mechanism is started to start the cleaning operation on the electrostatic oil fume purifier.

[0049] As Figures 2 to 4 shown, the cleaning system of the electrostatic oil fume purifier provided by the present invention includes a first detection mechanism, a second detection mechanism, a controller and a cleaning mechanism. The first detection mechanism, the second detection mechanism and the cleaning mechanism are all connected to the controller;

[0050] The first detection mechanism is used to detect arc occurrence information and send the detected arc occurrence information to the controller. The second detection mechanism is used to detect arc strike occurrence information and send the arc strike occurrence information to the controller.

[0051] The controller is used to receive the arc occurrence information and the arc strike occurrence information, and obtain the arc warning information of the electrostatic field of the electrostatic oil fume purifier and the arc strike warning information of the power supply of the electrostatic oil fume purifier according to the arc occurrence information and the arc strike occurrence information. When both the arc warning information and the arc strike warning information reach the preset requirements, the controller sends a cleaning instruction to the cleaning mechanism.

[0052] The cleaning mechanism receives the cleaning instruction and performs a cleaning operation on the electrostatic oil fume purifier.

[0053] The first detection mechanism is used to detect arc occurrence information, and the second detection mechanism is used to detect arcing occurrence information. The controller can receive the arc occurrence information and arcing occurrence information, and obtain the arc warning information of the electrostatic field of the electrostatic oil fume purifier and the arcing warning information of the power supply of the electrostatic oil fume purifier according to the arc occurrence information and arcing occurrence information. When both the arc warning information and the arcing warning information meet the preset requirements, the controller sends a cleaning instruction to the cleaning mechanism, and the cleaning mechanism performs a cleaning operation according to the cleaning instruction. By combining the arc occurrence information detected by the first detection mechanism and the arcing occurrence information detected by the second detection mechanism for judgment, it can truly reflect whether the electrostatic oil fume purifier needs to be cleaned, avoiding the situations of untimely cleaning and frequent cleaning.

[0054] It should be noted that the controller can be implemented by using a chip of model STM32F412, or a single-chip microcomputer of model STC12C5A60S2.

[0055] The controller can also receive parameters such as operation, fault, output voltage and current output by the power supply of the electrostatic oil fume purifier. After comprehensively evaluating by setting the preset number of times of the arcing warning information and the arc warning information, a cleaning instruction is sent to the cleaning mechanism, and the cleaning mechanism is started according to the cleaning instruction, so as to clean the electrostatic oil fume purifier.

[0056] It should be noted that the arc occurrence information includes continuously detecting the arcs generated by the electrostatic field of the electrostatic oil fume purifier and recording the time nodes of each arc for continuously calculating the time interval between two adjacent arcs; the arcing occurrence information includes continuously detecting the arcing of the power supply of the electrostatic oil fume purifier and recording the time nodes of each arcing for continuously calculating the time interval between two adjacent arcing.

[0057] In this embodiment, the controller can be a central processing unit. The first detection mechanism, the second detection mechanism and the cleaning mechanism are all connected to the central processing unit. The central processing unit can respectively process the arc occurrence information and arcing occurrence information of the first detection mechanism and the second detection mechanism, and send a cleaning instruction to the cleaning mechanism to control the cleaning mechanism to perform a cleaning operation.

[0058] It should be noted that the controller may also include a first processor, a second processor, and a third processor. The first processor is integrated with the first detection mechanism, enabling the first detection mechanism to collect arc light occurrence information and obtain arc light warning information based on the arc light occurrence information. The second processor is integrated with the second detection mechanism, enabling the second detection mechanism to collect arcing occurrence information and obtain arcing warning information based on the arcing occurrence information. The third processor is integrated with the cleaning mechanism and can receive the arc light warning information and the arcing warning information. When both the arc light warning information and the arcing warning information meet the preset requirements, a cleaning instruction is sent to the cleaning mechanism to control the cleaning mechanism to perform a cleaning operation.

[0059] It should be noted that the electrostatic oil fume purifier can also be connected to a cloud server, that is, the main controller is connected to the cloud server. The main controller can send cleaning signals, operating information of the high-voltage power supply, fault information, parameters such as output voltage and current to the cloud server. Users can remotely receive these information parameters and set and modify relevant parameters, which is convenient for remote control.

[0060] Furthermore, the first detection mechanism is a light sensor 100, and the light sensor 100 is arranged inside the electrostatic oil fume purifier.

[0061] Specifically, the first detection mechanism can be a light sensor 100, which is arranged inside the electrostatic oil fume purifier and is located at the front end of the electrostatic field generator 30 for collecting the arc light generated by the electrostatic field generator 30.

[0062] The second detection mechanism can be a signal processing module connected to the signal output end of the sampling and amplifying module. Among them, the sampling and amplifying module can be used to sample the current signal of the power supply to obtain a sampling signal, and amplify the sampling signal to a range where the signal processing module can distinguish the arcing critical point voltage and the reference voltage range. The signal processing module can be used to determine whether there is arcing and the arcing time interval, etc., according to the processed value of the sampled signal after comparison and amplification and the preset value. Those skilled in the art can use relevant devices in the prior art to implement the above functions according to actual needs. This is the prior art and will not be elaborated here.

[0063] The second detection mechanism is part of the power supply of the electrostatic oil fume purifier, and the power supply has functions such as continuous arcing alarm, open circuit protection, short circuit protection, etc., and has signals such as output voltage, current, operation, and short circuit fault.
