Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioner and its control method. Background Technology

[0002] Currently, the ion output devices of ion modules used in air conditioners have a fixed structure, with a fixed distance between the two or more output ion electrodes. Therefore, under the same current input, the ion module can only achieve one ion concentration and ozone concentration output, which cannot meet the different ion / ozone concentration requirements under different usage scenarios. The positive and negative ion output and ozone generation of positive and negative ion modules are greatly affected by the electrode spacing. When the electrode spacing between the positive and negative output electrodes is small, more positive and negative ions are neutralized, producing more high-energy and active substances, resulting in better sterilization. However, in this case, there are fewer residual positive and negative ions, the spatial transmission distance is short, and the positive / negative ions themselves have poor ability to combine with and settle dust and other particles in the air. Furthermore, a smaller electrode spacing results in a higher ozone concentration, which is better for surface sterilization but can easily lead to ozone accumulation in the space, causing user discomfort. When the distance between the positive and negative output electrodes is large, there is less contact between the positive and negative ions, resulting in more positive and negative ions remaining after neutralization. These remaining positive and negative ions come into contact with and settle microscopic substances such as dust in the air, thus achieving a better dust removal effect. At the same time, the ozone concentration is low. However, the settled microscopic substances, such as bacteria and viruses, are not effectively removed, thus posing a risk of secondary pollution. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an air conditioner in which the control module can control the heat exchange fan to adjust the wind speed and control the ion emission module to adjust the spacing between the positive and negative ion emitters, so that the air conditioner can enter a specific cleaning mode to meet different usage scenarios.

[0004] The present invention further proposes a control method for an air conditioner.

[0005] An air conditioner according to a first aspect of the present invention includes: a casing having a heat exchange air inlet and a heat exchange air outlet; a heat exchanger disposed within the casing; a heat exchange fan disposed within the casing, wherein a heat exchange airflow generated by heat exchange in the heat exchanger is output from the heat exchange air outlet under the operation of the heat exchange fan; an ion emission module disposed within the casing, the ion emission module including: a positive ion emission electrode and a negative ion emission electrode spaced apart, for neutralizing and diffusing generated negative and positive ions; the ion emission module further includes: a driving device and a housing, the positive ion emission electrode, the negative ion emission electrode and the driving device being disposed on the housing, the driving device being used to drive at least one of the positive ion emission electrode and the negative ion emission electrode to move, thereby forming different spacings between the positive ion emission electrode and the negative ion emission electrode to achieve different positive and negative ion concentration outputs; and a concentration detection module. Inside the housing and near the heat exchange air inlet, the concentration detection module includes: an ion concentration sensor and an ozone concentration sensor. The ion concentration sensor detects the ion concentration at the heat exchange air inlet, and the ozone concentration sensor detects the ozone concentration at the heat exchange air inlet. A control module is connected to the heat exchange fan, the ion emission module, and the concentration detection module. The heat exchange fan and the ion emission module receive control signals from the control module and, based on the control signals, switch the fan speed to the appropriate level and adjust the distance between the positive and negative ion emitters to correspond to the specified fan speed. When the ion concentration detected by the ion concentration sensor exceeds a preset value, or when the ozone concentration detected by the ozone concentration sensor exceeds a preset value, the control module controls the ion emission module to stop operating.

[0006] According to an embodiment of the air conditioner of the present invention, the driving device can adjust the distance between the positive ion emitter and the negative ion emitter, thereby controlling the concentration of positive and negative ions and the ozone concentration output by the ion emission module, thus meeting the usage requirements of the ion emission module under different scenarios. Furthermore, the control module responds to user commands to control the operation of the heat exchange fan and the ion emission module. When the heat exchange fan receives a control signal from the control module, it switches the fan speed; and when the ion emission module receives a control signal from the control module, it adjusts the distance between the positive and negative ion emitters, ensuring that the distance between the positive and negative ion emitters corresponds to the fan speed. Thus, based on the control signals issued by the control module, the air conditioner can enter a specific operating mode to meet different usage scenarios.

[0007] According to some embodiments of the present invention, the control module has a dust suppression mode. When the control module is configured to activate the dust suppression mode, it controls the driving device to adjust the distance between the positive ion emitter and the negative ion emitter to the maximum distance, and controls the heat exchange fan to switch to a medium speed or a higher speed.

[0008] According to some embodiments of the present invention, after the control module is configured to activate the dust suppression mode, the control module is configured to: after time t1, control the concentration detection module to detect the ion concentration value at the heat exchange air inlet; if the detected ion concentration value is greater than a preset ion concentration value, control the ion emission module to stop running, and keep the heat exchange fan running until time t2 and then shut down; if the detected ion concentration value is less than the preset ion concentration value, keep the ion emission module and the heat exchange fan running until time t2 and then shut down, wherein t2 > t1.

[0009] According to some embodiments of the present invention, the control module has a sterilization mode. When the control module is configured to activate the sterilization mode, it controls the drive device to adjust the distance between the positive ion emitter and the negative ion emitter to the minimum distance, and controls the heat exchange fan to switch to a high-speed fan or a higher speed.

[0010] According to some embodiments of the present invention, after the control module is configured to activate the sterilization mode, the control module is configured to: after time t3, control the concentration detection module to detect the ion concentration value or ozone concentration value at the heat exchange air inlet; if the detected ion concentration value is greater than a preset ion concentration value or the ozone concentration value is greater than a preset ozone concentration value, control the ion emission module to stop running, and keep the heat exchange fan running until time t4 and then shut down; if the detected ion concentration value is less than a preset ion concentration value or the ozone concentration value is less than a preset ozone concentration value, keep the ion emission module and the heat exchange fan running until time t4 and then shut down, wherein t4 > t3.

[0011] According to some embodiments of the present invention, the control module is configured to control the driving device to adjust the distance between the positive ion emitter and the negative ion emitter to the minimum distance, and to control the heat exchange outlet to close and the heat exchange fan to reverse and switch to a low speed; after time t5, the control module to stop running, and the heat exchange fan to continue running until time t6, after which it is turned off.

[0012] According to some embodiments of the present invention, the control module is configured to control the driving device to adjust the distance between the positive ion emitter and the negative ion emitter to an intermediate distance, and to control the heat exchange outlet to operate continuously.

[0013] According to a second aspect of the present invention, in the control method of an air conditioner, after the air conditioner is started, the control module responds to the cleaning command of the air conditioner and controls the air conditioner to enter different cleaning modes, including: dust reduction mode, sterilization mode, self-cleaning mode, full cleaning mode, and general mode; the control module sends control signals to the heat exchange fan and the ion emission module according to the cleaning command, so that the heat exchange fan switches to the corresponding speed setting according to the control signal, and the drive device adjusts the distance between the positive ion emission electrode and the negative ion emission electrode to correspond to the speed setting.

[0014] According to some embodiments of the present invention, if the received cleaning instruction is a dust reduction mode, the driving device adjusts the distance between the positive ion emitter and the negative ion emitter to the maximum distance, and controls the heat exchange fan to switch to a medium speed or higher speed. After time t1, the concentration detection module is controlled to detect the ion concentration value at the heat exchange air inlet. If the detected ion concentration value is greater than a preset ion concentration value, the ion emission module is controlled to stop running, and the heat exchange fan continues to run until time t2 and then shuts down. If the detected ion concentration value is less than the preset ion concentration value, the ion emission module and the heat exchange fan continue to run until time t2 and then shut down, where t2 > t1.

[0015] According to some embodiments of the present invention, if the received cleaning instruction is a sterilization mode, the driving device adjusts the distance between the positive ion emitter and the negative ion emitter to the minimum distance, and controls the heat exchange fan to switch to a high-speed fan or higher speed. After time t3, the concentration detection module is controlled to detect the ion concentration value or ozone concentration value at the heat exchange air inlet. If the detected ion concentration value is greater than a preset ion concentration value or the ozone concentration value is greater than a preset ozone concentration value, the ion emission module is controlled to stop running, and the heat exchange fan continues to run until time t4 and then shuts down. If the detected ion concentration value is less than a preset ion concentration value or the ozone concentration value is less than a preset ozone concentration value, the ion emission module and the heat exchange fan continue to run until time t4 and then shut down, where t4 > t3.

[0016] According to some embodiments of the present invention, if the received cleaning command is a self-cleaning mode, the driving device is controlled to adjust the distance between the positive ion emitter and the negative ion emitter to the minimum distance, and the heat exchange outlet is controlled to close and the heat exchange fan is reversed and switched to a low speed; after time t5, the ion emission module is controlled to stop running, and the heat exchange fan continues to run until time t6 and then shuts down.

[0017] According to some embodiments of the present invention, if the received cleaning instruction is a full cleaning mode, the full cleaning mode includes: the dust reduction mode, the sterilization mode and the self-cleaning mode. The air conditioner is controlled to first enter the dust reduction mode, and after the dust reduction mode is completed, it enters the sterilization mode, and after the sterilization mode is completed, it enters the self-cleaning mode, and after the self-cleaning mode is completed, it exits.

[0040] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0041] The following is for reference. Figures 1-16 An air conditioner and a control method according to embodiments of the present invention are described.

[0042] like Figures 1-11 As shown, the air conditioner 100 includes: a casing 1, a heat exchanger (not shown in the attached drawing), a heat exchange fan (not shown in the attached drawing), and an ion emission module 20.

[0043] The casing 1 is provided with a heat exchange air inlet 11 and a heat exchange air outlet 12. The heat exchanger and the heat exchange fan are both located inside the casing 1. The heat exchange airflow formed by heat exchange by the heat exchanger is output from the heat exchange air outlet 12 under the drive of the heat exchange fan.

[0044] Thus, by operating the heat exchange fan, airflow from outside the casing 1 is introduced into the casing 1 through the heat exchange inlet 11, and heat exchange is formed through the heat exchanger. Driven by the operation of the heat exchange fan, the heat exchange airflow is output outward through the heat exchange outlet 12, achieving the effect of cooling or heating the indoor airflow to reach the user's desired comfortable temperature. In addition, a heat exchange duct (not shown in the attached figure) is provided inside the heat exchanger for the passage of heat exchange air. The heat exchange duct corresponds to the heat exchanger and is connected to the heat exchange outlet 12. Air from outside the casing 1 enters the heat exchange duct, and through the operation of the heat exchanger and the heat exchange fan, the air conditioner 100 can achieve the cooling and heating effects.

[0045] Specifically, the air conditioner 100 can be a wall-mounted indoor unit. The casing 1 includes a rear panel and a front panel facing away from each other. The rear panel is used for fixed installation on the wall, and the front panel can be equipped with a display panel to display information such as the working status of the indoor unit and indoor temperature and humidity. The front panel can also be equipped with function buttons such as a power button. The space between the front panel and the rear panel forms a heat exchange air duct. The air conditioner 100 also includes a top cover connecting the front panel and the rear panel. The top cover is located on top of the front panel and the rear panel, and a heat exchange air inlet 11 is opened on the top cover, allowing air to enter the casing 1.

[0046] Furthermore, an ion emission module 20 is disposed within the housing 1. The ion emission module 20 includes a positive ion emission electrode 21 and a negative ion emission electrode 22 spaced apart, so that the generated negative and positive ions are neutralized and diffused outward. Thus, the positive ion emission electrode 21 is used to emit positive ions, and the negative ion emission electrode 22 is used to emit negative ions. The emitted positive and negative ions neutralize each other, generating high-energy and active substances, thereby achieving a sterilization effect. In addition, the unneutralized positive and negative ions can also come into contact with and settle microscopic substances such as dust in the air, thereby achieving a sterilization effect.

[0047] Furthermore, the positive and negative ion output and ozone generation of the ion emission module 20 are significantly affected by the electrode spacing. Specifically, when the spacing between the positive ion emitter 21 and the negative ion emitter 22 is small, more positive and negative ions are neutralized, resulting in a higher concentration of high-energy and active substances. This leads to better sterilization, but fewer residual positive and negative ions remain. The short spatial transmission distance also reduces the ability of the positive / negative ions to combine with and settle dust and other particles in the air. Simultaneously, the ozone concentration is higher, which can easily lead to ozone accumulation and discomfort for users. When the spacing between the positive ion emitter 21 and the negative ion emitter 22 is larger, there is less contact between the positive and negative ions, resulting in more residual positive and negative ions after neutralization. In this case, the remaining positive and negative ions come into contact with and settle dust and other microscopic substances in the air, resulting in better dust removal. However, the ozone concentration is lower. In this case, the settled microscopic substances, such as bacteria and viruses, are not effectively removed, posing a risk of secondary pollution.

[0048] Therefore, the ion emission module 20 also includes a driving device 23 and a housing 24. The positive ion emitter 21, the negative ion emitter 22, and the driving device 23 are all disposed on the housing 24. The driving device 23 is used to drive at least one of the positive ion emitter 21 and the negative ion emitter 22 to move, so that different spacings are formed between the positive ion emitter 21 and the negative ion emitter 22, thereby achieving different positive and negative ion concentrations output. In other words, the driving device 23 can drive at least one of the positive ion emitter 21 and the negative ion emitter 22 to move, and can adjust the spacing between the positive ion emitter 21 and the negative ion emitter 22. By using different spacings, the positive and negative ion concentrations and ozone concentrations output by the ion emission module 20 can be controlled, thereby meeting the usage requirements of the ion emission module 20 in different scenarios.

[0049] Specifically, when indoor sterilization is required, the drive device 23 moves at least one of the positive ion emitter 21 and the negative ion emitter 22 to reduce the distance between them. This results in greater neutralization of positive and negative ions, producing more high-energy and active substances, leading to better sterilization. Conversely, when indoor dust removal is required, the drive device 23 moves at least one of the positive ion emitter 21 and the negative ion emitter 22 to increase the distance between them. This reduces contact between positive and negative ions, resulting in more residual positive and negative ions after neutralization. These residual ions can then come into contact with and settle dust and other microscopic particles in the air, resulting in better dust removal. Furthermore, after sterilization, the distance between the positive ion emitter 21 and the negative ion emitter 22 can be adjusted back to reduce the distance to effectively remove settled microscopic particles such as bacteria and viruses, thus preventing secondary pollution.

[0050] Compared to existing ion output devices with fixed structures and fixed distances between two or more output ion electrodes, which can only achieve one ion concentration and one ozone concentration output under the same current input, the ion emission module 20 in this invention can meet the different ion concentration / ozone concentration requirements under different usage scenarios.

[0051] In addition, the positive ion emitter 21 and the negative ion emitter 22 are composed of plastic fasteners and output materials. The plastic fasteners are on the outside and are used to wrap and fix the output materials in the middle. The output materials are on the inside and can be carbon brushes or steel needles, used to excite the air to generate ions by the voltage and current conducted from the ion output line.

[0052] In addition, the air conditioner 100 also includes a concentration detection module (not shown in the attached drawings) and a control module (not shown in the attached drawings). The concentration detection module is located inside the casing 1, near the heat exchange air inlet 11. The concentration detection module includes an ion concentration sensor (not shown in the attached drawings) and an ozone concentration sensor (not shown in the attached drawings). The ion concentration sensor is used to detect the ion concentration value at the heat exchange air inlet 11, and the ozone concentration sensor is used to detect the ozone concentration value at the heat exchange air inlet 11.

[0053] Furthermore, the control module is connected to the heat exchange fan, the ion emission module 20, and the concentration detection module. The heat exchange fan and the ion emission module 20 receive control signals from the control module and, based on these signals, switch the heat exchange fan to the appropriate fan speed setting. They also adjust the distance between the positive ion emitter 21 and the negative ion emitter 22 using the drive device 23, ensuring this distance corresponds to the fan speed setting. In other words, the heat exchange fan receives a control signal from the control module to switch its fan speed, and the ion emission module 20 receives a control signal from the control module to adjust the distance between the positive ion emitter 21 and the negative ion emitter 22, ensuring this distance corresponds to the fan speed setting. Essentially, when the distance between the positive and negative ion emitters 21 and 22 is a fixed value, the switched fan speed is also fixed. Thus, based on the control signals from the control module, the air conditioner 100 can enter a specific operating mode to meet different usage scenarios. For example, when sterilization is required indoors, the control module controls the drive device 23 to move at least one of the positive ion emitter 21 and the negative ion emitter 22 so that the distance between the positive ion emitter 21 and the negative ion emitter 22 is smaller. At the same time, the control module controls the speed of the heat exchange fan to switch to the corresponding speed, such as the high speed. In this case, more positive and negative ions are neutralized, resulting in more high-energy and active substances. Under the action of high-speed wind, it can be ensured that the energy and high-energy ions generated after the neutralization of positive and negative ions can be effectively transferred to the room, and the sterilization effect reaches the best.

[0054] Furthermore, when the ion concentration value detected by the ion concentration sensor exceeds a preset value, or when the ozone concentration value detected by the ozone concentration sensor exceeds a preset value, the control module controls the ion emission module 20 to stop operating. In other words, during the operation of the ion emission module 20, if the ion concentration value detected by the ion concentration sensor at the heat exchange air inlet 11 exceeds a preset value (where the preset value is the upper limit of the indoor ion concentration), it indicates that the ion emission module 20 no longer needs to generate ions, and the control module can control the ion emission module 20 to stop operating.

[0055] Therefore, by driving at least one of the positive ion emitter 21 and the negative ion emitter 22 to move via the drive device 23 in the ion emission module 20, the distance between the positive ion emitter 21 and the negative ion emitter 22 can be adjusted, thereby controlling the positive and negative ion concentrations and ozone concentrations output by the ion emission module 20, thus meeting the usage requirements of the ion emission module 20 in different scenarios. Furthermore, the control module responds to user commands to control the operation of the heat exchange fan and the ion emission module 20. When the heat exchange fan receives a control signal from the control module, it switches the fan speed; when the ion emission module 20 receives a control signal from the control module, it adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22, ensuring that the distance between the positive ion emitter 21 and the negative ion emitter 22 corresponds to the fan speed. Thus, according to the control signals issued by the control module, the air conditioner 100 can enter a specific operating mode to meet different usage scenarios.

[0056] Furthermore, the control module has a dust suppression mode. When the control module is configured to activate the dust suppression mode, the control drive device 23 adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22 to the maximum distance, and controls the heat exchange fan to switch to a medium-speed or higher speed setting. In other words, when the control module activates the dust suppression mode and adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22 to the maximum distance, the neutralization of positive and negative ions is less, and the residual positive and negative ions (single ions) are more abundant. These are then delivered into the room at a medium-speed or higher speed to bind and settle indoor microorganisms (dust, microorganisms), thereby achieving a better dust suppression effect.

[0057] Preferably, after the dust suppression mode is activated by the control module, the distance between the positive ion emitter 21 and the negative ion emitter 22 is adjusted to the maximum distance, and the wind speed can be adjusted to the medium speed accordingly. This ensures that ions can be effectively delivered to the room, while preventing the accumulation of static electricity at the heat exchange outlet 12 from hindering ion output. Compared with adjusting to the high wind speed, this method can effectively save energy consumption while ensuring that ions can be effectively delivered to the room.

[0058] Generally, air conditioner 100 is equipped with at least three fan speed settings, including: low fan speed, medium fan speed and high fan speed.

[0059] Furthermore, after the control module is configured to start the dust suppression mode, the control module is configured as follows: after time t1, the concentration detection module detects the ion concentration value at the heat exchange air inlet 11. If the detected ion concentration value is greater than the preset ion concentration value, the ion emission module 20 is controlled to stop running, and the heat exchange fan continues to run until time t2 and then shuts down; if the detected ion concentration value is less than the preset ion concentration value, the ion emission module 20 and the heat exchange fan continue to run until time t2 and then shut down, where t2 > t1.

[0060] In other words, after the control module starts the dust suppression mode and runs for time t1, the control module controls the concentration detection module to detect the ion concentration value at the heat exchange air inlet 11. If the detected ion concentration value is greater than the preset ion concentration value, the ion emission module 20 is controlled to stop running, while the heat exchange fan continues to run until time t2 and then shuts down, exiting the dust suppression mode. If the detected ion concentration value is less than the preset ion concentration value, it means that the ion emission module 20 still needs to emit a certain amount of positive and negative ions for indoor dust suppression. In this case, the ion emission module 20 and the heat exchange fan continue to run until time t2 and then shut down, exiting the dust suppression mode.

[0061] Furthermore, the control module has a sterilization mode. When the control module is configured to activate the sterilization mode, the control drive device 23 adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22 to the minimum distance, and controls the heat exchange fan to switch to a high fan speed or higher. With this configuration, when the control module activates the sterilization mode and adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22 to the minimum distance, a greater amount of positive and negative ions are neutralized, resulting in more active substances and ozone. This ozone is then delivered into the room at a high fan speed, ensuring that the energy and high-energy ions generated after the neutralization of positive and negative ions are effectively delivered into the room, achieving a better sterilization effect.

[0062] Furthermore, after the control module is configured to start the sterilization mode, the control module is configured as follows: after time t3, the control concentration detection module detects the ion concentration value or ozone concentration value at the heat exchange air inlet 11. If the detected ion concentration value is greater than the preset ion concentration value or the ozone concentration value is greater than the preset ozone concentration value, the control ion emission module 20 stops running, and the heat exchange fan continues to run until time t4 and then shuts down; if the detected ion concentration value is less than the preset ion concentration value or the ozone concentration value is less than the preset ozone concentration value, the control ion emission module 20 and the heat exchange fan continue to run until time t4 and then shut down, where t4 > t3.

[0063] In other words, after the control module starts the sterilization mode and runs for time t3, the control module controls the concentration detection module to detect the ion concentration or ozone concentration at the heat exchange air inlet 11. If the detected ion concentration is greater than the preset ion concentration or ozone concentration is greater than the preset ozone concentration (the preset ion concentration is the upper limit of the indoor ion concentration, and the preset ozone concentration is the upper limit of the indoor ozone concentration), the ion emission module 20 is stopped, while the heat exchange fan continues to run until time t4 and then shuts down, exiting the sterilization mode. If the detected ion concentration is less than the preset ion concentration or ozone concentration is less than the preset ozone concentration, it means that the ion emission module 20 still needs to emit a certain amount of positive and negative ions for neutralization and sterilization. In this case, the ion emission module 20 and the heat exchange fan continue to run until time t4 and then shut down, exiting the sterilization mode.

[0064] Furthermore, the control module is configured to control the drive device 23 to adjust the distance between the positive ion emitter 21 and the negative ion emitter 22 to the minimum distance, and control the heat exchange outlet 12 to close and the heat exchange fan to reverse and switch to a low speed. After time t5, the control module 20 to stop running, and the heat exchange fan to continue running until time t6, after which it is turned off.

[0065] Thus, when the air conditioner 100 needs self-cleaning, the control module can control the drive device 23 to adjust the distance between the positive ion emitter 21 and the negative ion emitter 22 to the minimum distance, and control the heat exchange air outlet 12 to close and the heat exchange fan to reverse and switch to low speed, so as to perform sterilization and self-cleaning of the air duct / fan inside the air conditioner 100. After the working time t5 is met, the ion emission module 20 is turned off, and the heat exchange fan continues to run at low speed until time t6, after which the working mode is exited.

[0066] Furthermore, the control module is configured to control the drive device 23 to adjust the distance between the positive ion emitter 21 and the negative ion emitter 22 to the intermediate distance, and to control the heat exchange outlet 12 to operate continuously. Thus, when the control module controls the drive device 23 to adjust the distance between the positive ion emitter 21 and the negative ion emitter 22 to the intermediate distance, and controls the heat exchange outlet 12 to operate continuously, this operating mode is generally the normal mode of the air conditioner 100. That is, it can achieve a certain degree of sterilization and dust reduction, consistent with the current conventional ion module operating mode, but the effect is somewhat worse than the aforementioned dedicated sterilization / dust reduction mode.

[0067] like Figures 1-11 As shown, the working principle of the ion emission device 2 in the air conditioner 100 is further described.

[0068] The driving device 23 drives at least one of the positive ion emitter 21 and the negative ion emitter 22 to move, adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22, and thus controls the positive and negative ion concentration and ozone concentration output by the ion emission module 20, thereby meeting the usage requirements of the ion emission module 20 under different scenarios.

[0069] In one embodiment of the present invention, such as Figures 6-8 As shown, one of the positive ion emitters 21 and the negative ion emitter 22 is a movable emitter and is movably disposed on the housing 24, while the other emitter is a fixed emitter and is fixedly disposed on the housing 24. The driving device 23 drives the movable emitter to move relative to the fixed emitter.

[0070] In other words, one of the positive ion emitters 21 and the negative ion emitter 22 is a movable emitter, and the other emitter is a fixed emitter. In this way, the driving device 23 drives the movable emitter to move relative to the fixed emitter, thereby adjusting the distance between the positive ion emitter 21 and the negative ion emitter 22. The structure is simple, requiring only one emitter to move.

[0071] The driving device 23 includes a first driving member 25 and a transmission rack 26. The first driving member 25 has a first output shaft, which is connected to one end of the transmission rack 26. The other end of the transmission rack 26 is fixedly connected to the movable emitter. When the first output shaft of the first driving member 25 rotates, the transmission rack 26 drives the movable emitter to move relative to the fixed emitter. In this configuration, the first output shaft of the first driving member 25 is engaged with one end of the transmission rack 26, and the other end of the transmission rack 26 is fixedly connected to the movable emitter. When the first output shaft rotates, the transmission rack 26 moves, thereby driving the movable emitter to move relative to the fixed emitter.

[0072] Specifically, the first driving member 25 can be fixed to the outside of the housing 24, allowing the first output shaft to pass through the housing 24 and extend into the inside of the housing 24, thereby connecting with the transmission rack 26. Furthermore, the moving direction of the movable emitter is consistent with the transmission direction of the transmission rack 26, so that they move relative to each other towards the direction of the fixed emitter.

[0073] Furthermore, the outer casing 24 is provided with a first opening slot 241, through which the movable emitter passes and moves directionally. Since one end of the positive ion emitter 21 / negative ion emitter 22 is used to connect to the high-voltage output wire 42 of the high-voltage transformer 40, and the other end is used to generate positive / negative ions, the first opening slot 241 is provided on both sides of the outer casing 24 so that both ends of the movable emitter pass through the first opening slot 241 and move directionally within it, thereby ensuring that the direction of movement of the movable emitter remains constant.

[0074] Furthermore, the ion emission module 20 also includes: a first connector 27, a first guide groove 242 provided on the inner wall of the outer shell 24, one end of the first connector 27 being connected to the movable emitter, and the other end being fixed in the first guide groove 242, so that when the movable emitter moves in a direction in the first opening groove 241, one end of the first connector 27 moves in a direction in the first guide groove 242, wherein the first connector 27 and the movable emitter are perpendicular to each other.

[0075] Combination Figure 6 and Figure 7 As shown, at least two first guide grooves 242 are provided on the inner wall of the outer casing 24. Correspondingly, there are at least two first connectors 27. One end of the first connector 27 is fixedly connected to the movable emitter, and the other end is fixed in the first guide groove 242. When the movable emitter moves directionally along the first opening groove 241, one end of the first connector 27 moves directionally in the first guide groove 242 to avoid the movable emitter from moving back and forth or tilting during the movement.

[0076] It should be noted that in this embodiment, the movable emitter and the fixed emitter are vertically arranged, and the movable emitter moves in the left-right direction. The movable emitter moves left and right relative to the fixed emitter to adjust the distance between them. Furthermore, the first connecting member 27 is perpendicular to the movable emitter, which prevents the movable emitter from moving up and down or tilting during movement.

[0077] In another embodiment of the invention, such as Figures 9-11 As shown, both the positive ion emitter 21 and the negative ion emitter 22 are movable emitters and are movably mounted on the housing 24. The driving device 23 drives the positive ion emitter 21 and the negative ion emitter 22 to move closer to or further away from each other. With this configuration, the driving device 23 can drive the positive ion emitter 21 and the negative ion emitter 22 to move together, so that the positive ion emitter 21 and the negative ion emitter 22 move closer to or further away from each other.

[0078] The drive device 23 includes a second drive member 28 and a gear assembly 29. The gear assembly 29 includes a first gear 291, a second gear 292, and a third gear 293. The second drive member 28 has a second output shaft. One end of the second output shaft is drivenly engaged with the first gear 291. The first gear 291 is fixedly installed on one of the movable emitters. The other end of the second output shaft is drivenly engaged with the second gear 292. The second gear 292 is drivenly engaged with the third gear 293. The third gear 293 is fixedly installed on the other movable emitter. When the second output shaft of the second drive member 28 rotates, the two movable emitters move closer to each other or further away from each other.

[0079] Combination Figure 9 and Figure 10 As shown, the second output shaft of the second drive member 28 passes through the housing 24 to the inside of the housing 24 and meshes with the first gear 291 and the second gear 292 respectively. The first gear 291 is mounted on one of the movable emitters, and the two are fixed and cannot move relative to each other. When the first gear 291 rotates along the second output shaft, the movable emitter rotates, thereby causing the upper end of the movable emitter to retract towards the middle or expand outward, thereby achieving the adjustment of the pitch.

[0080] Furthermore, the second gear 292 meshes with both the second output shaft and the third gear 293. The third gear 293 is mounted on another movable emitter, and the two are fixed and cannot move relative to each other. The second gear 292 is used to cause the third gear 293 to rotate in the opposite direction to the first gear 291 during the rotation of the second output shaft. Thus, the rotation of the second output shaft can simultaneously cause the two movable emitters to either retract towards the center or expand to both sides.

[0081] Furthermore, a fixing hole is provided on the outer casing 24 for fixing the central shaft of the first gear 291, the second gear 292 and the third gear 293, so as to fix the first gear 291, the second gear 292 and the third gear 293.

[0082] Furthermore, the gear size, number of teeth, and tooth height of the present invention are only one embodiment. In actual design, the gear size and number of teeth can be determined according to requirements.

[0083] Furthermore, the outer casing 24 is provided with a second opening slot 243, through which two movable emitters pass and are spaced apart within the second opening slot 243. The two movable emitters are either close to or far from each other within the second opening slot 243. Specifically, the second opening slot 243 is provided on both sides of the outer casing 24, so that the two ends of the two movable emitters pass through the second opening slot 243 and move directionally within the second opening slot 243, thereby ensuring that the movement direction of the movable emitters is determined.

[0084] In another embodiment of the present invention, the driving device 23 includes: a third driving member (not shown in the figure) and a fourth gear (not shown in the figure). The third driving member has a third output shaft, one end of which is engaged with the fourth gear. The fourth gear is fixedly mounted on the movable emitter. When the third output shaft of the third driving member rotates, the movable emitter moves closer to or further away from the fixed emitter.

[0085] In other words, one of the positive ion emitters 21 and the negative ion emitter 22 is a movable emitter, and the other of the positive ion emitters 21 and the negative ion emitter 22 is a fixed emitter. Based on the scheme that the driving device 23 drives the movable emitter to move relative to the fixed emitter, the rotation of the third output shaft of the third driving member can cause the fourth gear to drive the movable emitter to move closer to or further away from the fixed emitter.

[0086] However, it should be noted that, unlike the first embodiment of the present invention, the movement of the active emitter relative to the fixed emitter does not mean that the active emitter moves left or right relative to the fixed emitter, but rather that it deflects or moves away from the fixed emitter.

[0087] In addition, the drive device 23 may also include a worm gear assembly, which can be used in conjunction with the gear assembly 29 in the above embodiments to adjust different movement directions depending on the transmission direction and output direction.

[0088] Of course, the driving device 23 described above is an embodiment of the present invention and is not limited to the driving device 23 described above.

[0089] In addition, the air conditioner 100 also includes an ion emission device 2, which includes a high voltage transformer 40 and an ion emission module 20. One end of the high voltage transformer 40 is provided with a high voltage input wire 41, and the other end is provided with a high voltage output wire 42. The high voltage output wire 42 is used to electrically connect to the ion emission module 20.

[0090] The high-voltage input wire 41 at one end of the high-voltage transformer 40 is used to connect the electronic control of the air conditioner 100 and the circuit in the high-voltage transformer 40, and is used to control the start and stop of the ion emission module 20. The high-voltage transformer 40 contains the control circuit of the ion emission module 20, which is used to convert the input current and voltage into the output current and voltage. The high-voltage output wire 42 at the other end of the high-voltage transformer 40 is connected to the ion emission module 20, and is used to conduct the output current and voltage converted by the high-voltage transformer 40 to the ion emission module 20.

[0091] Furthermore, the ion emission module 20 includes: an ion output wire 30, a positive ion emitter 21 and a negative ion emitter 22 penetrating the outer casing 24, with one end connected to the ion output wire 30 respectively, and a high-voltage output wire 42 electrically connected to the ion output wire 30. Thus, the high-voltage output wire 42 at the other end of the high-voltage transformer 40 is connected to the ion output wire 30 of the ion emission module 20, thereby conducting the output current and voltage converted by the high-voltage transformer 40 to the positive ion emitter 21 and the negative ion emitter 22 of the ion emission module 20. There are two ion output wires 30, connected to the positive ion emitter 21 and the negative ion emitter 22 respectively, and the two ion output wires 30 are respectively connected to the two high-voltage output wires 42 of the high-voltage transformer 40. Furthermore, the high-voltage transformer 40 can use a high-voltage AC power supply or a high-voltage pulse power supply.

[0092] Therefore, by driving at least one of the positive ion emitter 21 and the negative ion emitter 22 to move via the driving device 23, the distance between the positive ion emitter 21 and the negative ion emitter 22 can be adjusted. When sterilization is required indoors, the driving device 23 drives at least one of the positive ion emitter 21 and the negative ion emitter 22 to move, so that the distance between the positive ion emitter 21 and the negative ion emitter 22 is smaller. At this time, more positive and negative ions are neutralized, resulting in more high-energy and active substances, and thus a better sterilization effect. When dust removal is required indoors, the driving device 23 drives at least one of the positive ion emitter 21 and the negative ion emitter 22 to move, so that the distance between the positive ion emitter 21 and the negative ion emitter 22 is larger. This reduces the contact between positive and negative ions, resulting in more positive and negative ions remaining after neutralization. This allows the remaining positive and negative ions to contact and settle with microscopic substances such as dust in the air, resulting in a better dust removal effect. Furthermore, after sterilization, the distance between the positive ion emitter 21 and the negative ion emitter 22 can be adjusted to reduce the distance between them, so as to effectively remove the settled microscopic substances, such as bacteria and viruses, and prevent secondary pollution. Therefore, by changing the different distances between the positive ion emitter 21 and the negative ion emitter 22, the concentration of positive and negative ions and the concentration of ozone output by the ion emission module 20 can be controlled, thereby meeting the usage requirements of the ion emission module 20 in different scenarios.

[0093] According to the control method of the air conditioner 100 of the second aspect embodiment of the present invention, after the air conditioner 100 is started, the control module responds to the cleaning command of the air conditioner 100 and controls the air conditioner 100 to enter different cleaning modes, including: dust reduction mode, sterilization mode, self-cleaning mode, full cleaning mode, and general mode. Furthermore, the control module sends control signals to the heat exchange fan and the ion emission module 20 according to the cleaning command, so that the heat exchange fan switches to the corresponding fan speed according to the control signal, and the drive device 23 adjusts the distance between the positive ion emission electrode 21 and the negative ion emission electrode 22, corresponding to the fan speed. With this configuration, the control module can adjust the distance between the positive ion emission electrode 21 and the negative ion emission electrode 22 according to the user's input cleaning command, and coordinate with the fan speed adjustment to control the air conditioner 100 to enter different ion purification modes. For example, the user can control the air conditioner 100 to enter sterilization mode / dust reduction mode / self-cleaning mode / full cleaning mode / general mode by pressing a button on the remote control, or the air conditioner 100 can automatically enter different purification modes according to the program's operating time limit.

[0094] Furthermore, combined Figure 13 As shown, if the received cleaning command is in dust reduction mode, the drive device 23 adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22 to the maximum distance, and controls the heat exchange fan to switch to medium speed or higher speed. After time t1, the concentration detection module detects the ion concentration value at the heat exchange air inlet 11. If the detected ion concentration value is greater than the preset ion concentration value, the ion emission module 20 is controlled to stop running, and the heat exchange fan continues to run until time t2 and then shuts down. If the detected ion concentration value is less than the preset ion concentration value, the ion emission module 20 and the heat exchange fan continue to run until time t2 and then shut down, where t2 > t1.

[0095] With this setup, when the control module receives a cleaning command for dust suppression mode, the drive unit 23 receives a control signal from the control module to adjust the distance between the positive ion emitter 21 and the negative ion emitter 22 to the maximum distance. The heat exchange fan also receives a control signal from the control module to adjust the fan speed to medium or higher. Generally, adjusting to medium speed is sufficient, ensuring that ions can be effectively delivered indoors while preventing static electricity accumulation at the heat exchange outlet 12 from hindering ion output. After dust suppression mode is activated for time t1, a judgment is made to detect the ion concentration N at the heat exchange inlet 11. If the detected ion concentration N is greater than the preset ion concentration (upper limit of indoor ion concentration) Nmax, the ion emission module 20 stops working, maintains medium speed operation until time t2, and exits dust suppression mode. If the ion concentration N is less than the preset ion concentration (upper limit of indoor ion concentration) Nmax at time t1, the ion emission module 20 remains activated and the medium speed operation continues until time t2, and the dust suppression mode exits.

[0096] Furthermore, combined Figure 14 As shown, if the received cleaning command is for sterilization mode, the drive device 23 adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22 to the minimum distance, and controls the heat exchange fan to switch to a high speed or higher. After time t3, the control concentration detection module detects the ion concentration value or ozone concentration value at the heat exchange air inlet 11. If the detected ion concentration value is greater than the preset ion concentration value or the ozone concentration value is greater than the preset ozone concentration value, the control ion emission module 20 stops running, and the heat exchange fan continues to run until time t4 and then shuts down. If the detected ion concentration value is less than the preset ion concentration value or the ozone concentration value is less than the preset ozone concentration value, the ion emission module 20 and the heat exchange fan continue to run until time t4 and then shut down, where t4 > t3.

[0097] With this configuration, when the control module receives a cleaning command for sterilization mode, the drive device 23 adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22 to the minimum distance, and the heat exchange fan adjusts its speed to a high speed or higher. This effectively ensures that the energy and high-energy ions generated after ion neutralization are efficiently delivered to the room. After the sterilization mode is activated for time t3, a judgment is made to detect the ion concentration N or ozone concentration O at the heat exchange air inlet 11. If the detected ion concentration N is greater than the preset ion concentration value (upper limit of indoor ion concentration) Nmax or the ozone concentration O is greater than the preset ozone concentration value (upper limit of indoor ion concentration) Omax, the ion emission module 20 stops working and maintains a high fan speed or higher until time t4, then exits the mode. If at time t3 the ion concentration value N is less than the preset ion concentration value (upper limit of indoor ion concentration) Nmax or the ozone concentration value O is less than the preset ozone concentration value (upper limit of indoor ion concentration) Omax, then keep the ion emission module 20 on and run at medium speed until t4, and exit the sterilization mode.

[0098] Furthermore, combined Figure 15 As shown, if the received cleaning command is for self-cleaning mode, the control drive device 23 adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22 to the minimum distance, and controls the heat exchange air outlet 12 to close and the heat exchange fan to reverse and switch to low speed. After time t5, the control ion emission module 20 stops running, and the heat exchange fan continues to run until time t6, after which it shuts down. Thus, when the air conditioner 100 needs to be sterilized and self-cleaned, the control module controls the drive device 23 to adjust the distance between the positive ion emitter 21 and the negative ion emitter 22 to the minimum distance, and controls the heat exchange air outlet 12 to close and the heat exchange fan to reverse and switch to low speed to sterilize and self-clean the air duct / fan inside the air conditioner 100. After the working time t5 is met, the ion emission module 20 is shut down, and the heat exchange fan continues to run at low speed until time t6, after which the self-cleaning mode is exited.

[0099] Furthermore, combined Figure 16 As shown, if the received cleaning command is a full cleaning mode, the full cleaning mode includes: dust reduction mode, sterilization mode and self-cleaning mode. The air conditioner 100 is controlled to first enter the dust reduction mode, and after the dust reduction mode is completed, it enters the sterilization mode, and after the sterilization mode is completed, it enters the self-cleaning mode, and exits after the self-cleaning mode is completed.

[0100] Thus, after the air conditioner enters the full cleaning mode, it first enters the "dust reduction mode," then the "sterilization mode," and finally the "self-cleaning mode." After completing all three modes, it exits the mode. In other words, it first binds, fixes, and settles indoor microscopic substances (dust, microorganisms), then performs sterilization, and finally performs the air conditioner's self-cleaning.

[0101] In addition, when the air conditioner 100 enters the normal mode, the drive device 23 adjusts the distance between the positive ion emitter 21 and the negative ion emitter 22 to the middle distance and controls the heat exchange air outlet 12 to run continuously. This working mode is generally the normal mode of the air conditioner 100, that is, it can achieve a certain sterilization and dust reduction effect, which is consistent with the current conventional ion module operation.

[0102] Therefore, by driving at least one of the positive ion emitter 21 and the negative ion emitter 22 through the driving device 23 in the ion emission module 20, different spacings are formed between the positive ion emitter 21 and the negative ion emitter 22, so as to achieve different positive and negative ion concentration outputs and ozone concentration outputs. Then, with different fan speeds for air delivery, different cleaning needs of the air conditioner 100 can be met. The best performance can be achieved in scenarios such as dust reduction, sterilization, and ion self-cleaning. It has high flexibility and strong applicability.
