Description

Technical Field

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

[0002] Microorganisms such as bacteria, fungi, and viruses are everywhere in our lives, threatening people's health. As people's quality of life improves, they are also paying more and more attention to the quality of indoor air. The main sources of bacteria, fungi, and viruses in indoor air are people's living and activities indoors.

[0003] Currently, more and more air conditioners with ion generators are appearing on the market. Due to their superior purification and cleaning effects, they are widely used. Air conditioners with ion generators produce negative ions by ionizing the air with high-voltage electricity. Tiny particles suspended in the environment absorb negative ions, which in turn attract surrounding suspended particles, increasing their size and density, causing them to settle. This results in excellent purification and cleaning, but the sterilization effect is not significant. Summary of the Invention

[0004] To address the aforementioned shortcomings, the present invention aims to propose an air conditioner with a sterilization and purification module and its control method, thereby solving the problem that the existing air conditioners with ion generators do not have a significant sterilization effect.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An air conditioner with a sterilization and purification module includes an air conditioner body, a sterilization and purification module, a human body sensor, and a controller.

[0007] The air conditioner body is provided with an air outlet and an air guide baffle. The air guide baffle is rotatably installed on the air outlet, and the stationary position of the air guide baffle includes at least the ozone sterilization position.

[0008] The sterilization and purification module includes an ion generator and a metal electrode. The ion generator is installed at the air outlet. The metal electrode is installed on the surface of the air guide baffle facing the ion generator and is grounded. The sterilization and purification module has at least a first working mode, a second working mode, and a third working mode.

[0009] The controller is configured to control the sterilization and purification module to be in at least a first working mode, a second working mode, or a third working mode. When the sterilization and purification module is in the first or second working mode, the controller controls the air guide baffle to rotate to a non-ozone sterilization position, and the metal electrode is not directly opposite the emitting end of the ion generator. In the first working mode, the sterilization and purification module releases negative ions; in the second working mode, the sterilization and purification module releases negative ions and nano-water ions, or only nano-water ions. When the sterilization and purification module is in the third working mode, the controller controls the air guide baffle to rotate to an ozone sterilization position, and the metal electrode is directly opposite the emitting end of the ion generator. The sterilization and purification module releases ozone.

[0010] The human body sensor is electrically connected to the controller. The human body sensor is used to detect whether there is a person in the air supply area of ​​the air conditioner. The controller controls the sterilization and purification module to enter different working modes through the signal from the human body sensor. When the human body sensor detects that there is a person in the air supply area of ​​the air conditioner, it sends a signal to the controller, and the controller controls the sterilization and purification module to enter the first working mode or the second working mode.

[0011] Furthermore, the ion generator includes a high-voltage transformer, a carbon fiber rod, and an insulating sheath;

[0012] The carbon fiber rod is installed on the high voltage transformer, and the insulating sleeve is provided on the outer periphery of one end near the high voltage transformer.

[0013] Furthermore, the sterilization and purification module also includes a condensate collection tank and a water inlet. The condensate collection tank is used to store the condensate generated during the operation of the air conditioner, and the water inlet is used to humidify the outer periphery of the carbon fiber rod.

[0014] The input end of the water-guiding component is disposed in the condensate collection tank; the output end of the water-guiding component is movably installed inside the air conditioner, and the output end of the water-guiding component includes at least a first position state and a second position state, the first position state being around the outer periphery of the emitting end of the carbon fiber rod, and the second position state being away from the outer periphery of the emitting end of the carbon fiber rod.

[0015] In another embodiment, the input end of the water guide is disposed inside the air conditioner and can extend into or exit the condensate collection tank, and the output end of the water guide is arranged around the outer periphery of the emitter end of the carbon fiber rod.

[0016] Furthermore, the sterilization and purification module also includes a mounting base;

[0017] The mounting base is fixedly installed at the air outlet, and the ion generator is detachably installed on the upper surface of the mounting base and close to the air outlet;

[0018] The condensate collection tank is integrally formed on the upper surface of the mounting base and located on one side of the ion generator, with the opening of the condensate collection tank facing the carbon fiber rod.

[0019] Furthermore, it also includes limiting components;

[0020] The upper surface of the air guide baffle is provided with a mounting groove, and the metal electrode is limited and connected to the mounting groove by a limiting component.

[0021] Specifically, the limiting component includes an elastic element and a limiting plate;

[0022] The inner sides of the mounting groove are provided with mounting holes facing each other. One end of the elastic element is fixed in the mounting hole, and the other end is elastically connected to the limiting plate. The metal electrode is limited by the two limiting plates.

[0023] Specifically, the metal electrode is a metal ring, which is grounded via a grounding wire; the surface of the air guide baffle is provided with a wiring groove, which is connected to the mounting groove and is used to accommodate the grounding wire.

[0024] A control method for an air conditioner with a sterilization and purification module, applied to the air conditioner with a sterilization and purification module described above, the control method comprising the following steps:

[0025] Receive ozone sterilization commands from users;

[0026] Obtain detection information from the human body sensor and determine whether to execute the ozone sterilization command based on the detection information from the human body sensor.

[0027] If the detection information indicates that there is someone in the air supply area, the ozone sterilization command will be paused and the process of obtaining detection information from the human body sensor will be repeated.

[0028] When the detection information indicates that there is no one in the air supply area, the ozone sterilization command is executed, and the sterilization and purification module enters the third working mode.

[0029] Specifically, executing the ozone sterilization command includes: controlling the air guide baffle to rotate to the ozone sterilization position, starting the sterilization and purification module to enter the third working mode, controlling the air outlet wind speed at the lowest setting, and controlling the air outlet wind speed to increase when the preset time threshold is reached.

[0030] Furthermore, the air conditioner also includes a humidity sensor, which is electrically connected to the controller and is used to detect the air humidity around the carbon fiber rod.

[0031] The control method includes the following steps:

[0032] The system determines the current operating status of the air conditioner. When the sterilization and purification module enters the first or second working mode under the control of the controller, it acquires the current air humidity around the carbon fiber rod in real time.

[0033] Determine whether the air humidity is lower than a predetermined humidity threshold. If it is lower than the predetermined humidity threshold, generate and issue a notification instruction, or proceed to the second determination step.

[0034] The second judgment step is as follows: determine whether the air humidity is within 40%-85%. When it is less than 40%, control the output end of the water inlet to enter the first position state or control the input end of the water inlet to extend into the condensate water collection tank, and humidify the outer periphery of the carbon fiber rod by guiding the water absorption of the water inlet. When it is greater than 85%, control the output end of the water inlet to enter the second position state or control the input end of the water inlet to move out of the condensate water collection tank, and stop humidifying the outer periphery of the carbon fiber rod.

[0035] The technical solution provided by this invention may include the following beneficial effects:

[0036] 1. The ion generator is installed at the air outlet of the air conditioner body, and the metal electrode is installed on the air guide baffle. The controller operates the start and stop of the ion generator and the rotation or stillness of the air guide baffle. The sterilization and purification module has a first working mode (negative ion purification mode), a second working mode (sterilization, purification and humidification mode) and a third working mode (ozone sterilization mode). In the second working mode, the sterilization and purification module releases negative ions and nano water ions or only nano water ions under high pressure. The nano water ions play a safe sterilization role, and the water molecule clusters carried by the nano water ions are delivered to the room with the air conditioner, playing a uniform humidification role.

[0037] 2. By adding a human body sensor, when the sensor detects that someone is in the air supply area, the ozone sterilization command is paused, preventing the metal electrode of the air guide baffle from facing the ion generator. This ensures that the ion generator cannot work together with the metal electrode. At this time, the ion generator is activated to produce negative ions and / or nano water ions. When the sensor detects that no one is in the air supply area, the controller controls the rotation of the air guide baffle so that the metal electrode faces the ion generator. The ion generator and the metal electrode together form a sterilization and purification module. The controller controls the sterilization and purification module to produce ozone, which is then used to sterilize the air conditioning and air supply areas. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] like Figure 1 , Figure 2 and Figure 5 As shown, an air conditioner with a sterilization and purification module includes an air conditioner body 1, a sterilization and purification module, a human body sensor, and a controller.

[0050] The air conditioner body 1 is provided with an air outlet and an air guide baffle 11. The air guide baffle 11 is rotatably installed on the air outlet, and the stationary position of the air guide baffle 11 includes at least the ozone sterilization position.

[0051] The sterilization and purification module includes an ion generator 2 and a metal electrode 3. The ion generator 2 is installed at the air outlet. The metal electrode 3 is installed on the surface of the air guide baffle 11 facing the ion generator 2 and is grounded. The sterilization and purification module has at least a first working mode, a second working mode and a third working mode.

[0052] The controller is configured to control the sterilization and purification module to be in at least a first working mode, a second working mode, or a third working mode. When the sterilization and purification module is in the first or second working mode, the controller controls the air guide baffle 11 to rotate to a non-ozone sterilization position, and the metal electrode 3 is not directly opposite the emitting end of the ion generator 2. In the first working mode, the sterilization and purification module releases negative ions; in the second working mode, the sterilization and purification module releases negative ions and nano-water ions or only nano-water ions. When the sterilization and purification module is in the third working mode, the controller controls the air guide baffle 11 to rotate to an ozone sterilization position, and the metal electrode 3 is directly opposite the emitting end of the ion generator 2. The sterilization and purification module releases ozone.

[0053] The human body sensor is electrically connected to the controller. The human body sensor is used to detect whether there is a person in the air supply area of ​​the air conditioner. The controller controls the sterilization and purification module to enter different working modes through the signal from the human body sensor. When the human body sensor detects that there is a person in the air supply area of ​​the air conditioner, it sends a signal to the controller, and the controller controls the sterilization and purification module to enter the first working mode or the second working mode.

[0054] Existing air conditioners with ion generators produce negative ions by ionizing the air with high-voltage electricity. Negative ions can eliminate tiny particles suspended in the environment, providing excellent purification and cleaning effects, but their sterilization effect is not significant. For a sufficient sterilization effect, ozone is generally the preferred choice. Therefore, this invention proposes an air conditioner with a sterilization and purification module, comprising an air conditioner body 1, a sterilization and purification module, a human body sensor, and a controller. The sterilization and purification module includes an ion generator 2 and a metal electrode 3. The ion generator 2 is installed at the air outlet of the air conditioner body 1, and the metal electrode 3 is installed on the air guide baffle 11. The controller operates the start / stop of the ion generator 2 and the rotation or stationary position of the air guide baffle 11. The sterilization and purification module has the following three operating modes:

[0055] (1) First working mode (negative ion purification mode): When the metal electrode 3 on the air guide baffle 11 rotates to a position where it swings or stops at a position where it is not directly opposite to the negative ion generating end of the ion generator 2, if the air is dry at this time (specifically, the air humidity is less than 40%), the emitting end of the ion generator 2 releases negative ions under high pressure, and the negative ions purify the particulate matter in the air.

[0056] (2) Second working mode (sterilization, purification and humidification mode): When the metal electrode 3 on the air guide baffle 11 rotates to a position where it swings or remains stationary and is not directly opposite the negative ion generating end of the ion generator 2, if the air humidity is greater than 40% at this time, the emitting end of the ion generator 2 absorbs the moisture in the air and releases negative ions and nano water ions or only nano water ions under high pressure; the nano water ions play a safe sterilization role, and the water molecule clusters carried by the nano water ions are delivered to the room with the air conditioner, playing a humidification role;

[0057] (3) Third working mode (ozone sterilization mode): When the air guide baffle 11 rotates to a position where the metal electrode 3 is directly opposite the ion generator 2 and remains stationary, the ion generator 2, in conjunction with the grounded metal electrode 3, which acts as another discharge electrode, discharges at the emitting end to the metal electrode 3 under high voltage, generating ozone and negative ions. In addition to its sterilization effect, the addition of the metal electrode 3 increases the amount of ozone generated, thus eliminating odors in the air, while negative ions purify particulate matter in the air.

[0058] Based on the three operating modes mentioned above, and combined with the judgment settings of the human body sensor and the controller, the controller uses the signal from the human body sensor to control the sterilization and purification module to enter different operating modes. This ensures that the sterilization and purification module can only enter the third operating mode to generate ozone for sterilization when no one is present. Specifically, when the human body sensor detects that someone is in the air supply area of ​​the air conditioner, it sends a signal to the controller, which then controls the sterilization and purification module to enter either the first or second operating mode. In a specific embodiment, the controller prevents the ion generator from entering the third operating mode by controlling the air guide baffle 11 to prevent it from rotating to a position where the metal electrode 3 is directly opposite the ion generator 2. This avoids the excessive generation of ozone that could harm the human body, making it safer and more conducive to human health.

[0059] It should be noted that the negative ions generated above can adsorb particulate matter floating in the air, then aggregate and eventually settle, thus purifying the air. The nano-water ions generated above differ from negative ions in the air. Encased in water, these nano-water ions do not easily combine with oxygen and nitrogen in the air, allowing them to persist in the air for a long time. Their antibacterial effect is also closely related to their own composition. Encased in water, these nano-water ions can easily adhere to the surface of various bacteria, allowing their abundant hydroxyl radicals to fully contact the bacteria and extract hydrogen ions, combining with them to form water. This process inactivates the bacteria, achieving a sterilization effect. In addition to sterilization, nano-water ions can also penetrate deep into fibers, extracting hydrogen ions from odor-causing bacteria, thus deodorizing. Therefore, they inhibit bacterial growth and remove odors, further enhancing the sterilization effect of air conditioners with sterilization and purification modules. Furthermore, the water molecule clusters carried by the nano-water ions can replenish humidity in the air-blown space, improving the user's comfort and solving the problem of reduced humidity during air conditioner use.

[0060] When the air conditioner with the sterilization and purification module enters the second working mode, it does not require manual water addition, unlike existing external humidifiers. Moreover, the water molecule clusters produced by this technology provide a better user experience compared to existing technologies that use ultrasonic humidifiers to produce water particles. Furthermore, because the water molecule clusters are distributed along with the air conditioner's airflow, they can fill the entire space, while humidifiers can only humidify around the humidifier itself. This technology makes the humidity of the entire space more uniform.

[0061] To ensure maximum negative ion output, the ion generator 2 is installed in an unobstructed position in the middle of the air outlet of the air conditioner body 1 to avoid charge accumulation. In a specific embodiment, the ozone sterilization position of the air guide baffle 11 is such that the air guide baffle 11 is tilted upwards and forms a gap of 0.5-2cm with the air outlet. When the third working mode is started, the air guide baffle 11 is adjusted to the ozone sterilization position so that the metal electrode 3 is directly opposite and close to the ion generator 2, thereby forming ozone and negative ions. At first, the air conditioner fan speed is reduced, and at this time the air guide baffle 11 only leaves a small gap. The low fan speed allows the ozone to circulate inside the air conditioner body 1 to sterilize the inside of the air conditioner body 1. Then the fan speed is increased to sterilize the room.

[0062] Furthermore, the ion generator 2 includes a high-voltage transformer 21, a carbon fiber rod 22, and an insulating sheath 23;

[0063] The carbon fiber rod 22 is installed on the high voltage transformer 21, and the insulating sleeve 23 is provided on the outer periphery of one end near the high voltage transformer 21;

[0064] In existing technologies, negative ions are generated by the pulse oscillation circuit of the ion generator 2, which boosts low voltage to DC negative high voltage through a high-voltage module. This negative DC high corona discharge, generated by the needle tip discharge or the continuous generation of negative DC corona by the carbon fiber tip, rapidly emits a large number of electrons, which are captured by oxygen molecules in the air, thus forming negative ions. However, the needle tip discharge has the drawback of only working in dry conditions; it cannot work in humid conditions. Furthermore, over time, the needle tip surface becomes passivated and blackens, preventing the release of negative ions. Therefore, this technical solution uses a carbon fiber rod 22, which avoids the passivation problem. Moreover, the amount of negative ions released increases with usage time, a characteristic of the carbon fiber rod 22. Therefore, by replacing the emitter of the ion generator 2 with a carbon fiber rod 22, negative ions can be generated, effectively attracting and settling dust. An insulating sleeve 23 is provided at the end where the carbon fiber rod 22 connects to the high-voltage transformer 21, providing insulation and improving safety. Preferably, the insulating sleeve 23 is made of heat-shrink tubing.

[0065] The sterilization and purification module also includes a condensate collection tank 4 and a water inlet. The condensate collection tank 4 is used to store the condensate generated during the operation of the air conditioner, and the water inlet is used to humidify the outer periphery of the carbon fiber rod 22.

[0066] The input end of the water-guiding component is disposed in the condensate collection tank 4; the output end of the water-guiding component is movably installed inside the air conditioner, and the output end of the water-guiding component includes at least a first position state and a second position state. The first position state is around the outer periphery of the emitting end of the carbon fiber rod 22, and the second position state is away from the outer periphery of the emitting end of the carbon fiber rod 22.

[0067] In another embodiment, the input end of the water guide is disposed inside the air conditioner and can extend into or exit the condensate collection tank 4, and the output end of the water guide is arranged around the outer periphery of the emitting end of the carbon fiber rod 22.

[0068] The condensate collection tank 4 is used to store the condensate generated during air conditioner operation for humidification of the emitter. Through the condensate collection tank 4 and the water inlet device, when the air humidity is insufficient, the emitter of the carbon fiber rod 22 can be actively humidified, enabling the emitter to generate nano-water ions and improve the sterilization efficiency of the sterilization and purification module. When the generation of nano-water ions is not needed or the air humidity is sufficient, moving the input or output end of the water inlet device can stop the active humidification of the emitter.

[0069] It should be noted that the water-absorbing component is a strip-shaped absorbent cotton strip with hydrophilic properties.

[0070] In an optional embodiment, the sterilization and purification module further includes a water inlet pipe 5, one end of which is connected to the upstream end of the condensate outlet pipe of the air conditioner body 1, and the other end of which is connected to the water inlet of the condensate collection tank 4. Condensate in the air conditioner body 1 is led to the condensate collection tank 4 through the water inlet pipe 5.

[0071] In an optional embodiment, the sterilization and purification module further includes a water outlet pipe 6. One end of the water outlet pipe 6 is connected to the water outlet end of the condensate collection tank 4, and the other end of the water outlet pipe 6 is connected to the downstream end of the condensate outlet pipe of the air conditioner body 1 through a pumping device. When the air conditioner is not used for a long time, the water outlet pipe 6 can be used to drain the water in the condensate collection tank 4 to avoid water accumulation.

[0072] In another preferred embodiment, such as Figure 6 As shown in the schematic diagram, the sterilization and purification module also includes a water storage tank 01 and a pumping device 02. The water storage tank 01 is detachably installed on the outside of the air conditioner. The water storage tank 01 is used to store externally supplied water. The water storage tank 01 and the condensate collection tank 4 are connected by a pipe. The pipe is equipped with the pumping device 02, which is used to pump water from the water storage tank 01 into the condensate collection tank 4. The condensate collection tank 4 is also used to store externally supplied water. When the air conditioner is newly installed and started, if the water in the condensate collection tank 4 is insufficient, the transmitter can be humidified by externally supplied water. Preferably, external water is introduced through the detachable water storage tank 01 on the outside of the air conditioner. Users can remove the water storage tank 01, add water, and then reinstall it, making the operation simple.

[0073] Preferably, the sterilization and purification module further includes a mounting base 7;

[0074] The mounting base 7 is fixedly installed at the air outlet, and the ion generator 2 is detachably installed on the upper surface of the mounting base 7 and close to the air outlet;

[0075] The condensate collection tank 4 is integrally formed on the upper end surface of the mounting base 7 and located on one side of the ion generator 2. The opening of the condensate collection tank 4 faces the carbon fiber rod 22.

[0076] It should be noted that by installing mounting base 7 on the air outlet of air conditioner body 1, ion generator 2 can be installed on mounting base 7 and fixed with screws, which is convenient for disassembly and assembly; condensate water collection tank 4 is provided on one side of ion generator 2, and condensate water collection tank 4 is integrally formed on the upper end surface of mounting base 7, which reduces installation parts and improves production efficiency.

[0077] In a preferred embodiment, a limiting component 12 is also included;

[0078] The upper end face of the air guide baffle 11 is provided with a mounting groove 111, and the metal electrode 3 is limited and connected to the mounting groove 111 by a limiting component 12; it is understood that, as Figure 3 As shown, an installation groove 111 is provided on the upper end face of the air guide baffle 11. The metal electrode 3 is clamped in the installation groove 111 by the limiting component 12, which facilitates installation and does not affect the normal use of the air conditioner.

[0079] In specific embodiments, such as Figure 4 As shown, the limiting component 12 includes an elastic element 121 and a limiting plate 122; the inner side of the mounting groove 111 is provided with mounting holes 112 facing each other, one end of the elastic element 121 is fixed in the mounting hole 112, and the other end is elastically connected to the limiting plate 122, and the metal electrode 3 is limited by the two limiting plates 122; this arrangement facilitates the installation and disassembly of the metal electrode 3 and makes it easy to replace.

[0080] The metal electrode 3 is a metal ring, which is grounded through a grounding wire; the surface of the air guide baffle 11 is provided with a wiring groove, which is connected to the mounting groove 111 and is used to accommodate the grounding wire.

[0081] The ozone generation mechanism involves placing a carbon fiber rod 22 directly opposite a metal ring, approximately 1 cm away, with high voltage applied to both ends. The air between the electrodes is broken down by the high voltage, resulting in a discharge and the generation of ozone. Cable trays are used to neatly organize the wires, improving the aesthetics of the equipment.

[0082] A control method for an air conditioner with a sterilization and purification module, applied to the air conditioner with a sterilization and purification module described above, the control method comprising the following steps:

[0083] Receive ozone sterilization commands from users;

[0084] Obtain detection information from the human body sensor and determine whether to execute the ozone sterilization command based on the detection information from the human body sensor.

[0085] If the detection information indicates that there is someone in the air supply area, the ozone sterilization command will be paused and the process of obtaining detection information from the human body sensor will be repeated.

[0086] When the detection information indicates that there is no one in the air supply area, the ozone sterilization command is executed, and the sterilization and purification module enters the third working mode.

[0087] This method enables the air conditioner to release negative ions or nano-water ions to purify and clean the indoor environment, benefiting the user's health. It also ensures that when no one is present, a third operating mode is activated to generate ozone, sterilizing the air conditioner's interior and the indoor environment, further enhancing health and safety. Preferably, when the ozone sterilization command is paused, the controller also includes a reminder signal step. Specifically, this could be achieved by electrically connecting the controller to a buzzer to sound an alarm, or by electrically connecting the controller to an indicator light to flash, informing the user that the ozone sterilization command is paused and reminding them to leave the air conditioner's airflow area.

[0088] In another preferred embodiment of the control method, executing the ozone sterilization command includes: controlling the air guide baffle 11 to rotate to the ozone sterilization position, activating the sterilization and purification module to enter the third working mode, controlling the air outlet wind speed at the lowest setting, and increasing the air outlet wind speed when a preset time threshold is reached; the controller controls the air guide baffle 11 to rotate to the ozone sterilization position, at which time the air guide baffle 11 leaves only a gap, controlling the air conditioner fan to run at the lowest setting, using the lowest wind speed to allow ozone to circulate inside the air conditioner body 1. When the ozone content is not high, sterilization is first performed inside the air conditioner body 1. When the preset time threshold is reached (the preset time threshold is pre-deployed in the algorithm of the air conditioner controller by the manufacturer, specifically determined based on the ozone generation), when the sterilization of the air conditioner body 1 is completed, the air conditioner fan is controlled to switch wind speeds and increase the wind speed to sterilize the room, improving sterilization efficiency. When the user temporarily pauses the third working mode, the ozone generated during the pause can effectively sterilize the inside of the air conditioner body 1.

[0089] In another preferred embodiment, the air conditioner with the sterilization and purification module further includes a humidity sensor, which is electrically connected to the controller and is used to detect the air humidity around the carbon fiber rod 22.

[0090] The control method includes the following steps:

[0091] The system determines the current operating status of the air conditioner. When the sterilization and purification module enters the first or second working mode under the control of the controller, it acquires the air humidity around the carbon fiber rod 22 in real time. It determines whether the air humidity is lower than the predetermined humidity threshold. If it is lower than the predetermined humidity threshold, it generates and issues a notification command, or proceeds to the second determination step.

[0092] The second judgment step is as follows: determine whether the air humidity is within 40%-85%. When it is less than 40%, control the output end of the water-guiding component 5 to enter the first position state or control the input end of the water-guiding component to extend into the condensate water collection tank 4, and humidify the outer periphery of the carbon fiber rod 22 by the water absorption guidance of the water-guiding component 5. When it is greater than 85%, control the output end of the water-guiding component 5 to enter the second position state or control the input end of the water-guiding component to move out of the condensate water collection tank 4, and stop humidifying the outer periphery of the carbon fiber rod 22.

[0093] The preset humidity threshold can be either the user's preferred humidity level input via the app, or it can be configured in the air conditioner's controller during manufacturing, with the manufacturer using big data analysis to determine the optimal humidity for human comfort. It's important to note that the app communicates with the air conditioner's controller. When the current humidity level falls below the preset threshold, the app notifies the user, allowing them to switch the air conditioner's operating mode. Alternatively, it can be pre-set to trigger a second judgment step when the current humidity level drops below the preset threshold, achieving intelligent humidification. By setting the humidity sensor, a comfortable humidity level can be maintained.
