[0002] In the related art, there is a streamer sterilization device based on dielectric barrier discharge (DBD) installed on the air conditioner, which includes electrodes that are spaced and arranged opposite to each other. During the discharge process, the electrodes can ionize the air to generate plasma, which can effectively kill bacteria in the air duct of the air conditioner and in the room, and purify the air well. However, every time the plasma is generated by ionization, dust will be deposited on the electrode, affecting the subsequent sterilization effect.

However, with the above solution, some special locations, such as the electrodes located on the leeward side of the air conditioning wind, cannot be cleaned, resulting in different impedances between the anode and cathode of the electrode, causing the electrode to short-circuit, further reducing the sterilization effect of the streamer sterilization device.

[0058] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0060] In the related art, the streamer sterilization device can be applied to air conditioners, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the position of the streamer sterilization module installed in the air conditioner. Specifically, the streamer sterilization device can generally be installed in the position of the air duct of the air conditioner. The streamer sterilization module generates plasma when working. Plasma has a good sterilization effect. When applied to the air conditioner, it can effectively kill bacteria in the air duct of the air conditioner and in the room, and purify the air well. In particular, its intermittent working mode not only has a good sterilization effect, but also can inhibit the production of ozone.

[0061] In the related art, in order to reduce the driving voltage of streamer sterilization, the streamer sterilization device is provided with a special structure of electrodes. Figure 2 As shown, the streamer sterilization device is provided with a first cathode 22, an anode 23 and a second cathode 24 from top to bottom, the anode 23 is provided between the first cathode 22 and the second cathode 24, and the first cathode 22 and the second cathode 24 are provided above and below. With the above structure, with the same cross-sectional area, the distance between the anode and the cathode is only half of that of the monopole, and at this time, the driving voltage can be half of that of the monopole.

[0062] However, although the streamer sterilization device can be placed at the air outlet of the air conditioner, during operation, under the action of the air conditioner wind, the dust on the leeward side 23a of the anode 23 and the second cathode 24 cannot be blown away by the wind. As a result, the anode leeward side 23a and the second cathode 24 are heavily dusted and cannot be cleaned. Moreover, due to the action of gravity, the second cathode 24 is more likely to accumulate dust than the first cathode 22. When the second cathode 24 is heavily dusted, the resistance of the second cathode 24 to the anode 23 increases compared to that of the first cathode 22 to the anode 23, that is, the impedance of the anode 23 and the first cathode 22 is different from the impedance of the anode 23 and the second cathode 24.

[0063] In addition, the dust accumulated on the electrode surface is easy to form small pointed protrusions, so that the electrode surface begins to have an uneven structure. When the electrode is applied with high voltage, these small pointed protrusions are easy to gather near the electrodes, and a pointed discharge phenomenon occurs, which in turn reduces the dielectric constant and causes the breakdown threshold of the electrode to decrease. Therefore, some spaces where the breakdown threshold is reduced are more easily broken down by voltage, forming a conductive circuit in the air, which is equivalent to a short circuit. Finally, the anode 23 only discharges to the first cathode 22, and the second cathode 24 is equivalent to being short-circuited, and the sterilization effect is halved.

[0064] Based on this, the present application embodiment provides a streamer sterilization device, referring to Figure 3 and Figure 4 , the streamer sterilization device comprises:

[0065] A power drive circuit, a plasma generator 2 and a motor 1 that operate based on a drive power output by the power drive circuit;

[0066] The plasma generator 2 comprises at least two electrodes and a frame body 21 for carrying the at least two electrodes, wherein the at least two electrodes are spaced apart and arranged opposite to each other;

[0067] The output shaft 11 of the motor is connected to the frame body 21 and is used to drive the frame body 21 to drive at least two electrodes to rotate.

[0068] It can be understood that the power drive circuit converts the low-voltage input power into a high-voltage square wave output, so that the plasma generator 2 works under the drive of the high-voltage square wave. During the working process, the air will be ionized to produce free radicals and highly oxidizing molecules, etc., to achieve sterilization, deodorization and other effects, and achieve the purpose of streamer sterilization.

[0069] It is understandable that the plasma generator 2 includes at least two electrodes and a frame body 21 for carrying the at least two electrodes, wherein the at least two electrodes are spaced apart and arranged opposite to each other. Here, the shape of the frame body 21 is not limited, and the shape of the frame body 21 includes but is not limited to at least one of the following: a cuboid, a cube, and a cylinder.

[0070] It is understandable that the motor 1 here refers to an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. The main function of the motor 1 is to generate a driving torque as a power source for electrical appliances or various machines. The motor 1 includes an output shaft 11 of the motor 1, one end of the output shaft 11 of the motor 1 is connected to the frame body 21, and under the drive of the motor 1, the frame body 21 can be driven through the output shaft 11 of the motor and the at least two electrodes in the frame body 21 can be driven to rotate.

[0071] Exemplarily, the frame body 21 includes: a first carrier plate 211, a second carrier plate 212 and a third carrier plate 213 arranged from top to bottom, at least two electrodes include: an anode 23, a first cathode 22 and a second cathode 24, the first cathode 22 is fixed to the first carrier plate 211, the anode 23 is fixed to the second carrier plate 212, and the second cathode 24 is fixed to the third carrier plate 213.

[0072] It can be understood that the frame body 21 includes a first carrier plate 211, a second carrier plate 212 and a third carrier plate 213 arranged from top to bottom, and at least two electrodes include: a first cathode 22, an anode 23 and a second cathode 24, and the first cathode 22 is fixed on the first carrier plate 211, the anode 23 is fixed on the second carrier plate 212, and the second cathode is fixed on the third carrier plate 213.

[0073] In this way, by driving the frame body 2 to drive at least two electrodes to rotate through the output shaft 11 of the motor, the direction of the electrodes can be flexibly controlled, which is convenient for cleaning, effectively reduces the amount of dust accumulated on the electrodes, avoids short circuit of the electrodes, and thus improves the sterilization effect of the streamer sterilization device.

[0074] Exemplarily, power lines of the anode 23, the first cathode 22 and the second cathode 24 are led out through the output shaft 11 of the motor and then connected to the power drive circuit.

[0075] It is understandable that, in order to realize that the power lines of the first cathode 22, the anode 23 and the second cathode 24 can rotate with the motor 1, the power lines of the anode 23, the first cathode 22 and the second cathode 24 are respectively connected to the power drive circuit after being converged at the output shaft 11 of the electrode. Specifically, one end of the first cathode 22 is fixed to the first carrier plate 211, and the other end of the first cathode 22 passes through the frame body 21 to the output shaft 11 of the motor 1, and one end of the anode 23 is fixed to the second carrier plate 212, and the other end of the anode 23 passes through the frame body 21 to the output shaft 11 of the motor 1. One end of the power line of the second cathode 24 is fixed to the third carrier plate 213, and the other end of the second cathode 24 passes through the frame body 21 to the output shaft 11 of the motor 1.

[0076] It is understandable that in order to generate sufficient sterilization factors in the streamer sterilization device, high voltage is generally loaded on both ends of the plasma generator 2, and correspondingly, the power line generally needs to be a high-voltage resistant line.

[0077] For example, the power lines of the first cathode 22, the second cathode 24 and the anode 23 can be high-voltage lines with a resistance of at least 5KV to prevent discharge due to the close distance when the two wires are close together and pass through the rotating shaft. Here, the power lines converge at the output shaft 11 of the motor 1, so that the frame body 21 does not need to have additional holes, and the high-voltage wires do not need to be exposed to the outside, thereby improving the safety of the streamer sterilization device.

[0078] Exemplarily, the device further comprises:

[0079] A fan, used for introducing air into the plasma generator 2;

[0080] The current detection module is connected to the plasma generator 2 and is used to detect the current of each electrode of the plasma generator 2 .

[0081] It can be understood that a fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fans generally include ventilators and blowers.

[0082] It can be understood that the current detection module is connected to the plasma generator 2 and is used to detect the current of each electrode of the plasma generator 2 .

[0083] Exemplarily, the device further comprises:

[0084] A controller, the controller comprising a first terminal connected to the power drive circuit, a second terminal connected to the motor 1, a third terminal connected to the fan, and a fourth terminal connected to the current detection module;

[0085] The controller controls the working state of the power driving circuit based on the first terminal;

[0086] The controller controls the working state of the motor 1 based on the second terminal;

[0087] The controller adjusts the wind speed of the fan based on the third terminal;

[0088] The controller receives the current value of each electrode of the plasma generator 2 detected by the current detection module based on the fourth terminal.

[0089] It is understandable that the controller here can be a microcontroller MCU (Microcontroller Unit, microcontroller), such as Figure 4 As shown, the controller includes a first terminal a, a second terminal b, a third terminal c and a fourth terminal d. The control of the controller includes: control of the power drive circuit, motor control, wind speed control and current detection.

[0090] Exemplarily, the controller controls the working state of the power drive circuit based on the first terminal a, and the working state of the power drive circuit includes the start, operation and stop of the power drive circuit. The controller controls the working state of the motor 1 based on the second terminal b, and the working state of the motor 1 includes the start, operation and stop of the motor 1. The controller adjusts the wind speed of the fan based on the third terminal c, and the adjustment of the wind speed of the fan here includes controlling the fan to run at the target wind speed. The controller receives the current value of each electrode of the plasma generator 2 detected by the current detection module based on the fourth terminal d.

[0091] The present application also provides a control method for the streamer sterilization device of the above embodiment. The specific process is as follows: Figure 5 As shown:

[0092] Step 501: Obtaining operating parameters of the streamer sterilization device;

[0093] Step 502: Based on the operating parameters, the motor is controlled to start running and enter the cleaning mode of the clean streamer sterilization device.

[0094] Here, the operating parameters of the streamer sterilization device are parameters of the streamer sterilization device during operation.

[0095] Here, it is necessary to first control the motor to start running based on the operating parameters of the streamer sterilization device. When the motor starts running, the streamer sterilization device enters the cleaning mode.

[0096] In some embodiments, the operating parameters include at least one of the following: operating time, current value of each electrode, and based on the operating parameters, controlling the motor to start the operation includes:

[0097] It is determined that the running time is greater than or equal to a first set time threshold, and / or it is determined that the current value of at least one electrode is less than or equal to a set current threshold, and the motor is controlled to start running.

[0098] Here, the operating time refers to the operating time of the streamer sterilization device, and may also be the operating time of the equipment on which the streamer sterilization device is installed. For example, the streamer sterilization device is installed on an air conditioner, and the operating time here may also be the operating time of the air conditioner. Generally speaking, the longer the operating time of the air conditioner, the more dust is accumulated in the streamer sterilization device. Similarly, the longer the operating time of the streamer sterilization device, the more dust is accumulated accordingly.

[0099] Exemplarily, determining that the running time is greater than or equal to a first set time threshold, and / or determining that the current value of at least one electrode is less than or equal to a set current threshold, then controlling the motor to start running includes:

[0100] Time accumulation method: determine that the running time is greater than or equal to the first set time threshold, and control the motor 1 to start running.

[0101] Current detection method: determine that the current value of at least one electrode is less than or sets a current threshold, and control the motor 1 to start running.

[0102] Time and current detection method:

[0103] (1) When it is determined that the running time is greater than or equal to a first set time threshold and when it is determined that the current value of at least one electrode is less than or equal to a set current threshold, the motor is controlled to start.

[0104] (2) When the running time is less than a first set time threshold and when it is determined that the current value of at least one electrode is less than or equal to a set current threshold, the motor is controlled to start.

[0105] In some embodiments, the control method further includes:

[0106] In response to the running time of the cleaning mode reaching a second set time threshold, the cleaning mode is exited, the motor 1 is controlled to stop rotating, and the current value of at least one electrode corresponding to the time of exiting the cleaning mode is obtained;

[0107] The set current threshold is updated to the current value of at least one electrode corresponding to when the cleaning mode is exited.

[0108] Exemplarily, after the motor enters the cleaning mode, the motor may be controlled to exit the cleaning mode and control the motor to stop rotating in response to the running time of the cleaning mode reaching a second set time threshold.

[0109] Exemplarily, when exiting the cleaning mode, in order to ensure the next cleaning can proceed smoothly, the set current threshold needs to be updated, that is, the current value of at least one electrode corresponding to when exiting the cleaning mode is obtained, and the set current threshold is updated to the current value of at least one electrode corresponding to when exiting the cleaning mode.

[0110] In some embodiments, in the cleaning mode, the control method further includes:

[0111] Control the fan to run at the target wind speed.

[0112] Here, in the cleaning mode, the fan can be controlled to operate at a target wind speed to direct the wind into the streamer sterilization device. The target wind here can be the maximum wind speed of the fan.

[0113] In this way, under the effect of the maximum wind speed, as much dust as possible in the streamer sterilization device can be blown away, the streamer sterilization device can be cleaned, and the sterilization effect can be improved.

[0114] In some embodiments, in the cleaning mode, the control method further includes:

[0115] Controlling the motor to drive at least two electrodes to rotate intermittently;

[0116] The intermittent rotation includes a set angle range for each rotation and the motor stops rotating for a set time.

[0117] Here, in the cleaning mode, the motor can also be controlled to drive at least two electrodes to rotate intermittently, and the intermittent rotation includes each rotation of a set angle range and the motor stops rotating for a set time. Specifically, the intermittent rotation means that the motor will stop rotating for a set time every rotation of the set angle range, so that the intermittent rotation of the motor can drive at least two motors to rotate intermittently.

[0118] For example, Figure 6 As shown, while controlling the motor to drive the frame body 21 to drive at least two electrodes to rotate intermittently, the motor can rotate clockwise or counterclockwise, and the fan can be controlled to run at a target wind speed to introduce wind into the frame body, so that the wind can remove dust from the second cathode 24 and the leeward side 23a of the anode. Most importantly, even if the dust is not completely removed, under the action of the rotating electrode, the dust coverage of the first cathode 22 and the second cathode 24 is consistent, so that their impedance to the anode 23 is consistent, avoiding the short circuit of the electrode and the decrease in sterilization performance caused by unilateral discharge, and improving the sterilization performance.

[0119] In some embodiments, the control method further includes:

[0120] The accumulated rotation angle of the control motor in the rotation direction is less than or equal to the set angle threshold.

[0121] For example, Figure 3 As shown, during the rotation of the motor 1, in order to cause the power cords of the first cathode 22, the anode 23 and the second cathode 24 in the output shaft 11 of the motor 1 to be knotted too tightly or pulled apart, the cumulative rotation angle of the motor 1 in the rotation direction can be controlled to be less than or equal to a set angle threshold, where the set angle threshold can be 180 degrees.

[0122] Here, it can also be set that when the cumulative rotation angle is greater than a set angle threshold, the motor is controlled to stop rotating and exit the cleaning mode.

[0123] At this time, the current value of at least one electrode corresponding to when the cleaning mode is exited may also be obtained, and the set current threshold may be updated to the current value of at least one electrode corresponding to when the cleaning mode is exited.

[0124] The control method of the streamer sterilization device of the embodiment of the present application is described below with reference to an application example. In this application example, the streamer sterilization module is arranged at the air duct opening of the air conditioner, and the motor 1 is a stepping motor.

[0125] like Figure 2As shown, due to the effect of gravity, the second cathode 24 of the electrode is more likely to accumulate dust than the first cathode 22. When the dust accumulates to a certain amount, the impedance of the second cathode 24 to the anode 23 is greater than the impedance of the first cathode 22 to the anode 23. When the difference reaches a certain level, due to the tip discharge principle, the anode 23 will only discharge to the first cathode 22, and the second cathode 24 will be short-circuited, resulting in a decrease in the sterilization effect.

[0126] This application example can realize the self-cleaning of the streamer sterilization device and solve the problem of reduced sterilization effect caused by dust accumulation on the second cathode 24. The specific steps of the control method flow of this application example are as follows:

[0127] Step 701: Obtain the operating time T0 of the air conditioner.

[0128] Here, the operating status of the air conditioner can be monitored in real time, and the operating time T0 of the indoor unit of the air conditioner can be calculated. Generally speaking, when the air conditioner is running, the streamer sterilization device also runs.

[0129] Step 702: Determine whether the running time T0 exceeds a first set time threshold T_set.

[0130] Here, after the air conditioner has been running for a period of time, dust will accumulate in the streamer sterilization device. At this time, when determining whether T0 exceeds, that is, is greater than or equal to, the first set time threshold T_set, the self-cleaning function is started;

[0131] If yes, execute step 703 and step 706 ; if no, execute step 704 .

[0132] Step 703: Recalculate the running time T0.

[0133] After determining that the running time T0 has reached the first set time threshold T_set, it is proved that the streamer sterilization device needs to be cleaned at this time, and the stepper motor is controlled to start running and enter the cleaning mode;

[0134] At this time, the operating time T0 of the air conditioner also needs to be reset to zero and recalculated to prepare for the next cleaning of the streamer sterilization device.

[0135] Step 704: Obtain the current working current I1 of the streamer sterilization device.

[0136] When the operation time T0 of the indoor unit of the air conditioner does not exceed or is less than the first set time threshold T_set, it can also be determined whether to enter the cleaning mode based on the working current I1 of the streamer sterilization device. The working current I1 here is the current value of each electrode in the plasma generator.

[0137] Here, when unipolar discharge occurs at the electrodes, the operating current decays.

[0138] Reference Figure 3 Here, the unipolar discharge includes the anode 23 only discharging to the first cathode 22 or the anode 23 only discharging to the second cathode 24. That is, when dust accumulates in the streamer sterilization device, the anode 23 only discharges to the first cathode 22, and the current value of each electrode will decay. Therefore, it can be determined whether cleaning needs to be started by obtaining the current working current I1 of the streamer sterilization device.

[0139] Step 705: Determine whether the current operating current is less than or equal to the set current threshold I_set.

[0140] After obtaining the current operating current I1, the current operating current I1 is compared with the set temperature threshold I_set to determine whether the operating current I1 is less than or equal to I_set. If so, step 706 is executed; if not, step 701 is executed.

[0141] Step 706: Control the stepper motor to start running.

[0142] Step 707: Enter cleaning mode.

[0143] When the cleaning mode is activated, the controller starts the fan of the air conditioner and runs it at the maximum wind speed. At the same time, the stepper motor controls the electrode to rotate intermittently. The stepper motor can rotate at a certain angle θ (preferably 30 degrees) each time. After rotating to this angle, it runs for a period of time T1, allowing the wind to blow away the dust from this angle. Then it rotates to the next angle 2θ, and so on. In order to prevent the power cord in the output shaft of the stepper motor from being too tightly knotted or pulled off, the maximum angle of the motor rotation is controlled not to exceed 180 degrees.

[0144] Step 708: Exit cleaning mode.

[0145] When the rotation angle of the stepper motor exceeds 180 degrees, the cleaning mode is exited. Here, it can also be determined that the cleaning mode is exited when the running time of the cleaning mode reaches the second set time threshold T2.

[0146] Step 709: Update the preset current threshold I_set.
