[0002] With the increasing popularity of air conditioners, their internal air ducts are prone to dust accumulation over long-term use, generating bacteria and odors, which impact air quality and equipment efficiency. Existing technologies typically use condensed water on the evaporator surface for localized dust removal, but this passive cleaning method only removes surface dust and cannot completely remove stubborn dust accumulated within the enclosed air ducts.

[0003] In the current existing technology, this problem is mainly solved by detachable filters or manual regular cleaning. However, these methods have many shortcomings: (1) Reliance on removable filters: Existing technologies mainly use removable filters to reduce dust entering the system. Filters often cannot block all impurities, and especially when the filter is clogged, the cleaning ability will be greatly reduced.

[0004] (2) Manual regular cleaning: The dirt and bacteria accumulated in the air duct inside the air conditioner need to be cleaned regularly by professionals, which requires a lot of manpower and time. There is also a risk of equipment damage during the disassembly and cleaning process.

[0005] (3) Duct structure design: There are many difficult-to-reach areas in the duct structure, especially the complex structure around the fan. These areas are the main places for dust accumulation. Traditional methods are difficult to clean deeply in these areas, resulting in dirt accumulation and affecting air conditioning performance.

[0035] The following combination Figures 1 to 7 The present invention describes an air conditioning duct cleaning system, which comprises a housing 1 , a waterproof guide plate 2 , a cleaning device, a drainage device, and a drainage baffle 7 .

[0036] The shell 1 is formed with an air duct and a drain outlet, and the drain outlet is suitable for communicating with the air duct; the waterproof guide plate 2 is movably provided on the shell 1 for closing the air duct; the cleaning device is provided in the shell 1; the drain device is provided on the shell 1 and is suitable for communicating with the drain outlet; the drain baffle 7 is movably provided on the shell 1, and closes the drain outlet in the first position, and connects the drain device with the drain outlet in the second position.

[0037] Specifically, the shell 1 serves as the panel and supporting structure of the air conditioner, and an air duct for air outlet and a drain outlet for sewage discharge are formed inside. The present invention mainly focuses on cleaning the air duct, so the drain outlet is connected to the air duct.

[0038] When the air conditioning duct needs to be cleaned, the waterproof guide plate 2 is closed, sealing the duct, and the duct is cleaned by the cleaning device. It should be understood that the waterproof guide plate 2 used in the present invention is located inside the frame and is made of a polymer anti-seepage material. The surface is provided with bionic grooves to control water repellency. The waterproof guide plate 2 is internally provided with a self-retractable electric connecting rod to control the extension and contraction, thereby closing and opening the air duct.

[0039] The cleaning device is used to clean the air duct and the fan 4 inside it when the air duct is closed. Generally, a water storage tank is set inside the air conditioner, water is sprayed into the air duct, and the water is stirred in the air duct in conjunction with the rotation of the fan 4 to stir the water flow in the air duct. On the one hand, the inner wall of the air duct is cleaned, and on the other hand, the fan 4 is cleaned.

[0040] The drainage baffle 7 is located between the drainage device and the drainage outlet, and the drainage baffle 7 can be moved to a first position and a second position. When the drainage baffle 7 moves to the first position, the drainage outlet can be closed, thereby achieving the closure of the air duct, so that the air duct and the fan 4 inside it can be cleaned by the cleaning device, that is, Figure 3 When the drainage baffle 7 is moved to the second position, the drainage device is connected to the air duct, thereby draining the air duct after cleaning, that is, Figure 4 It is understood that the drainage device can be connected to an external drainage pipe for daily cleaning use.

[0041] As can be seen, by adding a cleaning device, a drainage device, and a drainage baffle 7, in conjunction with the internal equipment of the air conditioner, the air duct and fan 4 can be cleaned. The water flow stirred by the fan 4 can be used to clean the closed air duct more deeply than a detachable filter, especially the hard-to-reach areas around the fan 4, achieving a better cleaning effect. Compared with manual regular cleaning, it has the advantages of high efficiency, reduced labor waste, and low maintenance costs. The air conditioner air duct cleaning system provided by the present invention can not only improve the operating efficiency of the air conditioner, but also significantly improve the indoor air quality.

[0042] The present invention provides an air conditioner duct cleaning system, comprising: a housing 1, a waterproof guide plate 2, a cleaning device, a drainage device, and a drainage baffle 7. The housing 1 is formed with an air duct and a drainage port, and the drainage port is connected to the air duct; the waterproof guide plate 2 is movably disposed on the housing 1 for closing the air duct; the cleaning device is disposed within the housing 1; the drainage device is disposed on the housing 1 and is adapted to communicate with the drainage port; the drainage baffle 7 is movably disposed on the housing 1, and closes the drainage port in a first position and connects the drainage device to the drainage port in a second position. The air conditioner duct cleaning system provided by the present invention, by adding the cleaning device, the drainage device, and the drainage baffle 7, can complete the cleaning of the air duct and the fan 4 in conjunction with the internal equipment of the air conditioner. Compared with a detachable filter, it can deeply clean the closed air duct, especially the hard-to-reach areas around the fan 4, and has a better cleaning effect. Compared with manual regular cleaning, it has the advantages of high efficiency, reduced labor waste, and low maintenance cost. The air conditioner duct cleaning system provided by the present invention can not only improve the operating efficiency of the air conditioner, but also significantly improve the indoor air quality.

[0043] In one embodiment of the present invention, the air-conditioning duct cleaning system further includes: a controller, which is electrically connected to the cleaning device and the drain baffle 7, respectively, and is used to control the cleaning state of the cleaning device and the position of the drain baffle 7. The controller is installed in the air conditioner, and can control the cleaning state of the cleaning device and the position of the drain baffle 7, so as to realize the control of the cleaning state of the air conditioner. Specifically, the cleaning state includes the amount of cleaning water and the cleaning time, etc., and the position of the drain baffle 7 includes moving to the first position or the second position to realize the air duct sealing or sewage discharge function. Optionally, the controller is connected to the air conditioner remote control signal, and the controller can be remotely controlled by the air conditioner remote control to control the cleaning state of the cleaning device and the position of the drain baffle 7.

[0044] In one embodiment of the present invention, the air conditioner air duct cleaning system further includes: a dust detection device 3 and a fan 4. The dust detection device 3 is disposed within the air duct and electrically connected to a controller, and is configured to detect the level of dust accumulation within the air duct. The fan 4 is disposed within the air duct and electrically connected to the controller. The controller is configured to control the cleaning state of the cleaning device, the operating state of the fan 4 during the cleaning state, and the position of the drain baffle 7 based on the level of dust accumulation within the air duct. Specifically, the dust detection device 3 can employ an instrument such as an optical particle counter, a light scattering dust monitor, or a charge-based dust sensor to detect dust concentration, provided that such an instrument is waterproof. The fan 4 can employ a cross-flow fan 4 or an axial flow fan 4, such as those configured within the air conditioner. Based on the dust concentration detected by the dust detection device 3, the controller adjusts the cleaning state of the cleaning device, the operating state of the fan 4 during the cleaning state, and the position of the drain baffle 7, specifically adjusting the amount of water used for cleaning the device and the cleaning time, the speed, direction, and duration of the fan 4, and moving the drain baffle 7 to the first or second position. It can be seen that in this embodiment, by setting up the dust detection device 3, the dust concentration in the air conditioner can be automatically detected, and the air conditioner can be self-cleaned using the controller without human intervention. In addition, the dust concentration inside the air duct is monitored in real time by the sensor, and a suitable cleaning program is set according to the environmental conditions, thereby realizing intelligent cleaning.

[0045] In one embodiment of the present invention, a drainage device includes a drain plate 51 and a multi-layer filter membrane 52. The drain plate 51 has multiple drain holes 511, a drain channel 512, and a drain outlet 513. The drain holes 511 are adapted to communicate with the drain outlet, and the drain channel 512 connects between the drain holes 511 and the drain outlet 513. The multi-layer filter membrane 52 is sequentially disposed within the drain channel 512. Specifically, the drain plate 51 is a hollow structure with a drain channel 512 disposed therein. One side has drain holes 511 connected to the drain outlet, and one end has a drain outlet 513 connected to the drain hole 511 via the drain channel 512. The multi-layer filter membrane 52 is sequentially disposed along the drainage direction, filtering the wastewater before discharge. The filtered water can be circulated into a water storage tank to achieve water resource recycling. The drainage device can be periodically removed to clean the drain plate 51 and filter membrane 52.

[0046] In one embodiment of the present invention, Figure 7In the structure shown, a three-stage filter membrane 52 is arranged in the sewage plate 51, including: a primary filter membrane 52 arranged behind the sewage hole 511, a secondary filter membrane 52 arranged at the connection of the sewage channel 512, and a tertiary filter membrane 52 arranged at the sewage outlet 513. The three filter membranes 52 are all made of biological materials and can degrade dust impurities. The primary filter membrane 52 can filter particulate impurities larger than 100μm, the secondary filter membrane 52 can filter particulate impurities of 50-100μm, and the tertiary filter membrane 52 can filter particulate impurities of 10-50μm. The sewage passes through the filter membrane 52 and is discharged from the sewage outlet 513.

[0047] In one embodiment of the present invention, a cleaning device includes: a water storage tank (not shown), a water spray channel 61, and multiple water spray heads 62. The water storage tank is located within the housing 1; the water spray channel 61 is located within the housing 1 and extends along the length of the air duct; and the water spray heads 62 are located downstream of the water spray channel 61 and are evenly spaced along the length of the air duct. Specifically, a water storage tank is provided within the air conditioner, storing clean water for cleaning the air duct and fan 4. The water spray channel 61 extends the clean water to various parts of the air duct and sprays water at various locations on the inner wall of the air duct through the corresponding water spray heads 62 at its ends. Therefore, the water spray channel 61 and multiple water spray heads 62 of this embodiment can be used to clean the air duct once by spraying clean water. Subsequently, when the fan 4 is turned on, the air duct is agitated by the fan 4, thereby performing a secondary cleaning of the air duct.

[0048] In the above embodiment, the water spray channel 61 is an arched structure, and the height of the water spray channel 61 gradually increases from the two ends of the air duct to the center, and cooperates with the water spray head 62 to spray water into the air duct. That is to say, the water spray height in the central part of the air duct is the highest, and the water spray height gradually decreases from the center to the two ends. This is mainly because the central part of the air duct generally accumulates more dust, and spraying water from a higher position will have a better cleaning effect in one time, while the dust concentration accumulated at the two ends is lower, so water can be sprayed from a lower position.

[0049] In one embodiment of the present invention, a drainage groove 21 is formed on the waterproof guide plate 2, extending toward the drain outlet. In this embodiment, by forming the drainage groove 21 on the waterproof guide plate 2, condensed water can be collected and directed for drainage during air conditioning operation. After the air conditioning is cleaned, the drainage groove 21 can be used to guide any remaining wastewater to collect and drain out of the drain outlet.

[0050] In one embodiment of the present invention, the air conditioning duct cleaning system further includes: a first drive device 8 and a second drive device (not shown in the figure). The first drive device 8 is provided on the housing 1 and is connected to the drainage baffle 7 for driving the drainage baffle 7 to move to the first position or the first position; the second drive device is provided on the housing 1 and is connected to the waterproof guide plate 2 for driving the waterproof guide plate 2 to close the air duct. Specifically, the first drive device 8 is installed on the outside of the housing 1 and is in the form of a motor that can drive the drainage baffle 7 to move up and down. When the drainage baffle 7 is raised to the second position, the sewage discharge function can be realized. When the drainage baffle 7 is lowered to the first position, the air duct can be closed, thereby performing air conditioning cleaning; the second drive device is in the form of a motor and a connecting rod. The motor is provided on the inside of the housing 1 and is connected to the connecting rod. The connecting rod is provided on the waterproof guide plate 2.

[0051] like Figure 8 As shown, the present invention also provides a control method for an air conditioning duct cleaning system. The control method for an air conditioning duct cleaning system includes the following steps: S1. Obtain the dust accumulation level in the air duct; S2. Determine the cleaning status of the cleaning device according to the degree of dust accumulation in the air duct.

[0052] The present invention provides a control method for an air-conditioning duct cleaning system, which can determine the cleaning status according to the degree of dust accumulation in the air duct. The air-conditioning can be automatically self-cleaned without human intervention, thereby realizing intelligent cleaning control.

[0053] Specifically, the dust concentration in the air duct is detected by a sensor to determine the degree of dust accumulation in the air duct, and the degree of dust accumulation in the current air duct can be judged by comparing it with a preset dust concentration.

[0054] In one embodiment of the present invention, the cleaning state of the cleaning device is determined according to the dust accumulation level in the air duct, that is, step S2 specifically includes: S21, presetting a first dust concentration, a second dust concentration, and a third dust concentration from small to large, as well as a first water volume, a second water volume, and a third water volume of the cleaning device from small to large, and a first rotation time and a second rotation time of the fan 4 from large to small; S22: If the dust accumulation level in the air duct is less than the first dust concentration, control the cleaning device to clean with a first water volume, and rotate fan 4 clockwise for a first time period; If the dust accumulation level in the air duct is greater than or equal to the first dust concentration and less than the second dust concentration, the cleaning device is controlled to clean with the second water volume, and the fan 4 rotates clockwise for the first time and counterclockwise for the second time; If the dust accumulation level in the air duct is greater than or equal to the second dust concentration and less than the third dust concentration, the cleaning device is controlled to clean with a third amount of water, and the fan 4 rotates clockwise for the first time and counterclockwise for the second time; If the dust accumulation level in the air duct is greater than or equal to the third dust concentration, an alarm is sounded, and the cleaning device is controlled to clean with a third amount of water, and the fan 4 rotates clockwise for a first time length and counterclockwise for a second time length.

[0055] The present invention provides a preferred embodiment, in which the preset first dust concentration is 10 mg / m3, the second dust concentration is 12 mg / m3, and the third dust concentration is 15 mg / m3; the preset first water volume of the cleaning device is 30% of the total volume in the air duct, the second water volume is 40% of the total volume in the air duct, and the third water volume is 50% of the total volume in the air duct; the preset first rotation time of the fan 4 is 2 minutes, and the first time length is 1 minute.

[0056] Therefore, the control logic for the air duct cleaning system is as follows: First, the user activates cleaning mode, and waterproof guide plate 2 closes, sealing the air duct. Dust detector 3 then detects the dust concentration within the duct. When C1 is less than 10mg / m³, water inlet mode 1 is activated, with fan 4 rotating in mode 1 for cleaning. When 10≤C1<12mg / m³, water inlet mode 2 is activated, with fan 4 rotating in mode 2 for cleaning. When 12≤C1<15mg / m³, water inlet mode 3 is activated, with fan 4 rotating in mode 3 for cleaning. When C1 is greater than or equal to 15mg / m³, an alarm is triggered, reminding the user that repeated cleaning may be necessary. After this reminder, water inlet mode 3 is activated, with fan 4 rotating in mode 3 for cleaning. After cleaning is complete, the system drains the water, while the sewage recycling system simultaneously processes the wastewater and stores new clean water. Finally, waterproof guide plate 2 is opened to open the air duct, completing cleaning. Where C1 represents the dust concentration value reported by dust detection device 3; water inlet mode 1 is when the water volume in the air duct reaches 30% of the total air volume; water inlet mode 2 is when the water volume in the air duct reaches 40% of the total air volume; and water inlet mode 3 is when the water volume in the air duct reaches 50% of the total air volume. Fan 4 rotation mode 1 is when fan 4 rotates clockwise for 2 minutes; fan 4 rotation mode 2 is when fan 4 rotates clockwise for 2 minutes and counterclockwise for 1 minute; and fan 4 rotation mode 3 is when fan 4 rotates clockwise for 2 minutes and counterclockwise for 2 minutes.

[0057] The present invention further provides an air conditioner, comprising: the air conditioner air duct cleaning system in the above embodiment of the present invention, or a control method using the air conditioner air duct cleaning system in the above embodiment of the present invention.

[0058] The present invention provides an air conditioner, which includes the air conditioner air duct cleaning system of the present invention, or adopts the control method of the air conditioner air duct cleaning system of the present invention, and therefore has the same advantages as above.
