Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0025] This application provides a cleaning mechanism and an indoor air conditioning unit to solve the problem of cleaning the air conditioning drip tray. The following description is in conjunction with the accompanying drawings.

[0026] In the embodiments of this application, such as Figure 1 as well as Figure 2 As shown, the cleaning facility includes: Support frame 1 is configured to be installed on the indoor unit of air conditioner, and support frame 1 is slidably connected with a first slider 11 and a second slider 12; Cleaning component 2 is configured to clean the indoor unit of the air conditioner; and, Linkage 3 includes a first link 31 and a second link 32; One end of the first connecting rod 31 and one end of the second connecting rod 32 are coaxially connected and rotatably connected to the cleaning component 2. The other end of the first connecting rod 31 is rotatably connected to the first slider 11, and the other end of the second connecting rod 32 is rotatably connected to the first slider 11.

[0027] It should be noted that cleaning component 2 can be used to clean parts installed in the indoor unit of the air conditioner, such as the drip tray 5 or the grille. The indoor unit of the air conditioner can be a wall-mounted unit or a floor-standing unit.

[0028] Understandably, when the first slider 11 and the second slider 12 slide the same distance in the same direction, the cleaning component 2 can be moved to the target cleaning area. When the first slider 11 and the second slider 12 slide closer to each other, the straight-line distance between the cleaning component 2 and the support frame 1 is extended to get closer to the target cleaning area. When the first slider 11 and the second slider 12 slide away from each other, the straight-line distance between the cleaning component 2 and the support frame 1 is shortened, thus resetting the cleaning component 2. By changing the sliding direction of the first slider 11 and the second slider 12, the cleaning component 2 cleans the target cleaning area.

[0029] For example, the first slider 11 and the second slider 12 can be driven by different cylinders, or they can be driven by a known drive structure.

[0030] Specifically, there are two linkage groups 3 relative to the cleaning component 2. Both linkage groups 3 are coaxially connected to the cleaning component 2. The first link 31 of both linkage groups 3 is coaxially connected to the first slider 11, and the second link 32 of both linkage groups 3 is coaxially connected to the second slider 12.

[0031] In some embodiments, such as Figure 3 as well as Figure 4 As shown, the cleaning mechanism also includes a timing pulley set 4, which includes two rollers 41 and a timing belt 42 tensioned to the two rollers 41. The rollers 41 are rotatably connected to the support frame 1. The timing belt 42 is provided with multiple connecting parts, and at least two connecting parts are arranged at intervals on both sides of the roller 41 in the radial direction. The first slider 11 and the second slider 12 are detachably connected to at least one connecting part.

[0032] It should be noted that the first slider 11 and the second slider 12 can be connected and fixed to at least one connecting part using known detachable connection methods such as screwing, bonding, snap-fitting, and pin connection. "At least two connecting parts are arranged relatively spaced apart on both sides of the roller 41 in the radial direction" means that the two rollers 41 divide the area of ​​the synchronous belt 42 that is not in contact with it into a first conveying section 421 and a second conveying section 422. The first conveying section 421 is located above the second conveying section 422, and at least two connecting parts are located respectively in the first conveying section 421 and the second conveying section 422. It should be noted that the synchronous belt 42 is dynamically changing; therefore, the first conveying section 421 and the second conveying section 422 here do not refer to a fixed section on the synchronous belt 42.

[0033] Understandably, when two connecting parts are provided and located respectively in the first conveying section 421 and the second conveying section 422, the first slider 11 is connected to the connecting part located in the first conveying section 421, and the second slider 12 is connected to the connecting part located in the second conveying section 422. When the roller 41 rotates counterclockwise, the two connecting parts move away from each other, so that the first slider 11 and the second slider 12 move away from each other, and the cleaning part 2 rises. When the roller 41 rotates clockwise, the two connecting parts move closer to each other, so that the first slider 11 and the second slider 12 move closer to each other, and the cleaning part 2 descends. Alternatively, the length of the connecting part located in the first conveying section 421 can be increased so that it can be connected to the first slider 11 and the second slider 12. When the first slider 11 and the second slider 12 are simultaneously connected to the connecting part located in the first conveying section 421, translation of the first slider 11 and the second slider 12 can be realized. When the first slider 11 is connected to the connecting part located in the first conveying section 421 and the second slider 12 is connected to the connecting part located in the second conveying section 422, the first slider 11 and the second slider 12 can be moved closer to or further away from each other.

[0034] When there are three connecting parts, two of which are located in the first conveying section 421 and the other in the second conveying section 422, the first slider 11 and the second slider 12 can be simultaneously connected to the two connecting parts located in the first conveying section 421 to achieve translation of the cleaning component 2. Alternatively, the first slider 11 and the second slider 12 can be connected to one connecting part located in the first conveying section 421 and one connecting part located in the second conveying section 422 to achieve lifting of the cleaning component 2. Or, two connecting parts can be located in the second conveying section 422 and the other in the first conveying section 421.

[0035] When four connecting parts are provided, two are provided for each of the first conveyor segment 421 and the second conveyor segment 422. The first slider 11 can selectively connect to one connecting part on the first conveyor segment 421 and / or the second conveyor segment 422, and the second slider 12 can selectively connect to one connecting part on the first conveyor segment 421 and / or the second conveyor segment 422. When the first slider 11 and the second slider 12 are connected to only one connecting part and the connecting part is located on the first conveyor segment 421 and the second conveyor segment 422 respectively, the lifting and lowering of the cleaning component 2 can be achieved by controlling the rotation of the roller 41. When the first slider 11 and the second slider 12 are connected to only one connecting part and the connecting part is located on both the first conveyor segment 421 and the second conveyor segment 422, the movement of the cleaning component 2 in two directions can be achieved by changing the rotation of the roller 41. When the first slider 11 and the second slider 12 are simultaneously connected to the connecting parts located on the first conveyor segment 421 and the second conveyor segment 422, the current position of the cleaning component 2 is fixed.

[0036] By selectively connecting multiple connecting parts, the cleaning component 2 can achieve various movement states to achieve different cleaning purposes.

[0037] For example, the cleaning mechanism also includes a drive for driving the roller 41 to rotate forward or backward.

[0038] In another example, the support frame 1 is provided with a slide rail 13, and the first slider 11 and the second slider 12 are slidably connected to the slide rail 13 and located between the first conveying section 421 and the second conveying section 422.

[0039] In some embodiments, the plurality of connecting portions are a first connecting portion, a second connecting portion, a third connecting portion and a fourth connecting portion. The first connecting portion and the second connecting portion are arranged at intervals relative to each other on both sides of the roller 41 in the radial direction and are both used for detachable connection of the first slider 11. The third connecting portion and the fourth connecting portion are arranged at intervals relative to each other on both sides of the roller 41 in the radial direction and are both used for detachable connection of the second slider 12.

[0040] It should be noted that the first connecting part and the third connecting part are located in the first transmission segment 421, and the second connecting part and the fourth connecting part are located in the second transmission segment 422.

[0041] It is understandable that when the first slider 11 is connected to the first connecting part and the second slider 12 is connected to the third connecting part, or when the first slider 11 is connected to the second connecting part and the second slider 12 is connected to the fourth connecting part, the movement of the cleaning component 2 in two opposite directions is achieved by changing the direction of the roller 41. When the first slider 11 is connected to the first connecting part and the second slider 12 is connected to the fourth connecting part, or when the first slider 11 is connected to the second connecting part and the second slider 12 is connected to the third connecting part, the lifting and lowering of the cleaning component 2 is achieved by changing the direction of the roller 41.

[0042] Exemplarily, the first, second, third, and fourth connecting parts all employ slide tables, which are fixedly connected to the synchronous belt 42. Each of the four slide tables is provided with a first limiting groove, a second limiting groove, a third limiting groove, and a fourth limiting groove, respectively. The first slider 11 is provided with a first pin and a second pin; the first pin is used to insert into the first limiting groove, and the second pin is used to insert into the second limiting groove. The second slider 12 is provided with a third pin and a fourth pin; the third pin is used to insert into the third limiting groove, and the fourth pin is used to insert into the fourth limiting groove. The first, second, third, and fourth pins are all driven by electromagnetic means to achieve insertion or removal from the connecting parts; the specific electromagnetic driving method can employ techniques disclosed in this art.

[0043] In some embodiments, such as Figure 3 as well as Figure 5 As shown, the cleaning component 2 includes a connecting seat 21 and a cleaning head 22 movably connected to the connecting seat 21.

[0044] It should be noted that the cleaning head 22 can be connected to the connector 21 by sliding, rotating, or a combination of the above methods.

[0045] Understandably, by moving the cleaning head 22 in conjunction with the connecting seat 21, a small range of movement is achieved in the existing position, especially when the first slider 11 and the second slider 12 move to their extreme positions, thereby expanding the cleaning range through the movable cleaning head 22. For example, the cleaning head 22 can clean the target area by brushing the surface of the component or spraying detergent.

[0046] In some embodiments, such as Figure 5 As shown, the cleaning head 22 is rotatably connected to the connecting seat 21. The rotation axis of the cleaning head 22 is perpendicular to the rotation axis between the connecting rod assembly 3 and the cleaning component 2. Brushes 221 are provided on different surfaces of the cleaning head 22.

[0047] It should be noted that in this embodiment, the cleaning mechanism is mainly used to clean the water tray 5 in the indoor unit of the air conditioner.

[0048] It is understood that by rotating the cleaning head 22, the brush 221 continuously scrubs the target cleaning area to remove surface stains. For example, the cleaning head 22 adopts a plate-like structure, and brushes 221 are provided on the side of the cleaning head 22 away from the connecting seat 21 and at both opposite ends of the cleaning head 22. When the cleaning head 22 rotates, it can scrub the bottom wall and side wall of the water tray 5.

[0049] In some embodiments, such as Figure 5 As shown, the connecting seat 21 is provided with multiple baffles 211, which are spaced apart around the brush 221.

[0050] It should be noted that multiple baffles 211 are spaced apart from and surround the brush 221.

[0051] Understandably, the baffle 211 prevents impurities scraped off by the brush 221 during cleaning from splashing onto other components. For example, the distance from the side of the baffle 211 away from the connecting seat 21 to the end of the cleaning brush 221 away from the connecting seat 21 is greater than the depth of the water tray 5. This prevents the baffle 211 from interfering with the cleaning head 22's penetration into the water tray 5 for cleaning. Along the direction away from the connecting seat 21, the baffle 211 gradually moves away from the cleaning head 22. In this way, multiple baffles 211 form a trapezoidal structure to better prevent impurities from splashing and guide impurities splashed to the inside of the baffle 211 to fall into the water tray 5 under gravity, achieving centralized recycling.

[0052] In some embodiments, such as Figure 5 As shown, the connector 21 is equipped with a nozzle 23, which is used to spray cleaning fluid onto the cleaning head 22.

[0053] It should be noted that the cleaning solution can be water or a cleaning agent with physical and chemical cleaning properties.

[0054] Understandably, by spraying cleaning solution onto the water tray 5, the surface of the water tray 5 is moistened, and surface dirt is effectively removed.

[0055] This application also provides an indoor air conditioning unit, which includes the aforementioned cleaning mechanism and a water tray 5. The specific structure of the indoor air conditioning unit is as described in the above embodiments. Since this indoor air conditioning unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. Among them, the cleaning component 2 is used to clean the water tray 5.

[0056] It should be noted that the cleaning mechanism is located above the water tray 5. Two rollers 41 are arranged along the length of the water tray 5.

[0057] Understandably, by controlling the lifting and lowering of the cleaning component 2, the height of the cleaning component 2 is adjusted until it contacts the water receiving tray 5, and then the cleaning component 2 is moved horizontally to clean along the length of the water receiving tray 5.

[0058] In some embodiments, such as Figure 3 as well as Figure 6 As shown, the water receiving tray 5 is detachably connected to a drain pipe 51, and the drain pipe 51 is connected to the water receiving tray 5.

[0059] It should be noted that the drain pipe 51 is connected and fixed to the water receiving tray 5 using known detachable connection methods such as screw connection and snap connection.

[0060] Understandably, by removing the drain pipe 51 to clean the impurities blocking the connection between the drain pipe 51 and the water tray 5, the drain pipe 51 can be unblocked, ensuring normal drainage function.

[0061] In some embodiments, such as Figure 6 As shown, the drain pipe 51 is equipped with a first sensor 52, which is used to detect conductivity and send a first signal to the control system of the indoor unit of the air conditioner. The control system controls the cleaning mechanism based on the first signal. The water tray 5 is equipped with a second sensor 53, which is used to detect the liquid level and send a second signal to the control system. The control system controls the cleaning indicator light on the display panel of the indoor unit of the air conditioner based on the second signal.

[0062] It should be noted that the drip tray 5 is used to collect condensate from the heat exchanger in the indoor unit of the air conditioner.

[0063] Understandably, when the condensate collected in the drip tray 5 contains more impurities, its conductivity will increase. When the control system determines that the conductivity detected by the first sensor 52 is higher than the set conductivity threshold, it will control the cleaning mechanism to start cleaning the drip tray 5. When the drain pipe 51 becomes blocked, the water level in the drip tray 5 rises. When the control system determines that the liquid level detected by the second sensor 53 is higher than the set liquid level threshold, it will control the cleaning indicator light on the display panel to illuminate, prompting the user to unclog the impurities in the drain pipe 51.

[0064] In some embodiments, such as Figure 6 As shown, the drain pipe 51 is equipped with a filter screen 54, which is located near the connection between the drain pipe 51 and the water receiving tray 5. The first sensor 52 and the second sensor 53 are located below the filter screen 54.

[0065] It is understandable that larger impurities are left behind by filter 54.

[0066] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0067] The cleaning mechanism and air conditioning indoor unit provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
