Description

Technical Field

[0001] This application relates to the field of air conditioner technology, for example to an indoor unit and an air conditioner. Background Technology

[0002] The fan assembly of an air conditioner includes the duct sidewalls and the cross-flow fan. After prolonged use, dust accumulates on the duct sidewalls and the cross-flow fan, especially in environments with poor air quality. If it is not cleaned promptly and effectively, it will not only affect the performance of the air conditioner but also seriously affect the user's health.

[0003] A method for self-cleaning air ducts of an air conditioner is disclosed in the related technology. In the cooling mode, the refrigerant flow rate of the indoor heat exchanger is controlled so that condensation water is generated on the surface of the indoor heat exchanger; the cross-flow fan throws the condensation water dripping on the cross-flow fan onto the surface of the air duct to clean the surface of the air duct.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Due to the limitations of the operating mode, condensate needs to be generated by actively controlling the refrigerant flow of the heat exchanger in the cooling mode, and the generated condensate is used to clean the air duct; however, the generated condensate drips onto the cross-flow fan, and the cross-flow fan is not effectively cleaned.

[0060] Combination Figure 1-6As shown in the figure, this disclosure provides an indoor unit, including a fan assembly, a water tray assembly, a partition assembly, and a spray brush assembly. The water receiving tray assembly includes a tray body 100 and a top cover 103. The tray body 100 includes a front side plate 101 and a rear side plate 102, with the front side plate 101 facing the fan assembly. The top cover 103 is connected to the front side plate 101 and covers part of the opening of the tray body 100. A partition assembly is movably disposed within the tray body 100. The partition assembly, together with the front side plate 101 and the top cover 103, forms a relatively enclosed spray space 104, and together with the rear side plate 102, forms a top-open water receiving space 105, and the water receiving space 105 is connected to the spray space 104. A spray brush assembly is disposed on the side of the front side plate 101 opposite to the fan assembly and is connected to the spray space 104. The water receiving space 105 is used to collect condensate and can flow into the spray space 104. When the partition assembly moves toward the front side plate 101, it compresses the spray space 104, thereby causing the condensate to flow into the spray brush assembly and be sprayed toward the fan assembly.

[0061] The indoor unit provided in this embodiment has a panel 100 divided into a water-receiving space 105 and a water-spraying space 104 by a movable partition assembly. The top of the water-receiving space 105 is open to collect condensate, which can then enter the water-spraying space 104. When the partition assembly moves toward the front panel 101, the water-spraying space 104 is compressed, causing the condensate inside to flow into the spray brush assembly and spray onto the fan assembly. This allows for cleaning of the fan assembly using stored condensate, eliminating the need to use the condensate generated during cooling mode. Furthermore, the condensate is sprayed onto the fan assembly in the form of a water jet, which significantly improves the cleaning effect compared to condensate dripping onto the fan assembly.

[0062] Optionally, such as Figure 1 As shown, the fan assembly includes an air duct 410 and a cross-flow fan 400. The cross-flow fan 400 corresponds to the brush assembly; the air duct 410 is used to house the cross-flow fan 400, and a drainage channel 411 is provided at the bottom; the drainage channel 411 is used to drain the condensate sprayed by the brush assembly.

[0063] In this embodiment, the spray brush assembly sprays condensate water towards the cross-flow fan 400, effectively cleaning the fan as it rotates. Simultaneously, as the fan rotates, it throws condensate water onto the inner wall of the duct 410 and the vane 430 at the duct's outlet, effectively cleaning both the duct and the vane. The duct 410 is located below the cross-flow fan 400; the condensate water splashed onto its inner wall is discharged to the external environment through the drain channel 411, preventing condensate water accumulation within the duct.

[0064] Optionally, such as Figure 2As shown, the top cover 103 is connected to the top of the front panel 101, and the upper part of the water receiving space 105 serves as an opening for receiving condensate. The end of the heat exchanger 420 of the indoor unit is located above the water receiving space 105, and the condensate from the heat exchanger 420 falls into the water receiving space 105 for storage.

[0065] Optionally, such as Figure 3 As shown, the top cover 103 is connected to the upper middle part of the front side panel 101. Both the top of the water receiving space 105 and the top of the top cover 103 can serve as openings for receiving condensate. In this way, the tray 100 can store more condensate.

[0066] Optionally, the indoor unit also includes a water replenishment channel. The water replenishment channel is connected to the water receiving space 105 and is used to actively replenish water to the water receiving space 105. When the amount of condensate stored in the water receiving space 105 is insufficient to meet the water demand for cleaning, clean water is actively injected into the water receiving space 105 through the water replenishment channel, and then the fan assembly is cleaned.

[0067] Optionally, such as Figure 4 As shown, the front panel 101 has a water outlet 106, and the spray brush assembly includes a nozzle 300 and a soft brush 310. The nozzle 300 has a water spray channel 301 connected to the water outlet 106; the soft brush 310 is movably disposed in the water outlet 106, with its handle 311 facing the water spray space 104 and its brush head 314 facing the nozzle 300; the brush head 314 can extend from the water outlet 106 into the water spray channel 301, and extend out of the water spray channel 301 to contact the blower assembly.

[0068] In this embodiment, when the partition assembly moves toward the front side panel 101, the spray space 104 is compressed, causing the condensate inside to enter the spray channel 301 from the outlet 106 and then spray onto the fan assembly. Simultaneously, the soft brush 310 inside the outlet 106 extends into the spray channel 301 and then extends out of the spray channel 301 as a nozzle 300. This, combined with the rotation of the cross-flow fan 400, allows the condensate to be sprayed onto the cross-flow fan 400 and scrubbed by the soft brush 310, effectively improving the cleaning effect.

[0069] Optionally, the brush head 314 of the soft brush 310 is made of a flexible material, which can effectively reduce the damage to the cross-flow fan 400 when the brush head 314 is brushing the cross-flow fan 400.

[0070] Optionally, the inner wall of the water outlet 106 is provided with a limiting groove 107, which is opened along the moving direction of the soft brush 310; the brush handle 311 is provided with a limiting protrusion 312, and the limiting protrusion 312 slides in the limiting groove 107, thereby limiting the moving distance of the soft brush 310.

[0071] In this embodiment, the first end of the limiting groove 107 is close to the water inlet end of the water outlet 106, and the second end is close to the water outlet end of the water outlet 106. Under the action of the limiting protrusion 312, the soft brush 310 can only move within the range of the limiting groove 107, thereby preventing the soft brush 310 from coming out of the water outlet 106. When the limiting protrusion 312 of the brush handle 311 moves to the first end of the limiting groove 107, the brush head 314 is located inside the water outlet 106, such as... Figure 4 As shown. When the limiting protrusion 312 of the brush handle 311 moves to the second end of the limiting groove 107, the brush head 314 extends out of the nozzle 300 and contacts the cross-flow fan 400, as shown. Figure 5 As shown.

[0072] Optionally, the handle 311 of the soft brush 310 is shaped to match the water outlet 106, and its size is slightly smaller than that of the water outlet 106. The size of the brush head 314 is smaller than that of the handle 311, thus ensuring that the soft brush 310 can move freely within the water outlet 106.

[0073] Optionally, such as Figure 6 As shown, the soft brush 310 has corresponding support protrusions 313 on both sides of the brush handle 311, and the inner wall of the water outlet 106 has a support groove that matches each support protrusion 313. The support groove is opened along the moving direction of the soft brush 310, and the support protrusion 313 can move along the support groove. Under the action of the support protrusion 313, a gap is formed between the brush handle 311 and the water outlet 106, ensuring that the condensed water in the water spray space 104 can be sprayed out from the spray brush assembly through the water outlet 106.

[0074] For example, both the brush handle 311 and the water outlet 106 are constructed as cylinders, with the cross-sectional diameter of the brush handle 311 slightly smaller than that of the water outlet 106. A support protrusion 313 is provided on each of the left and right sides of the brush handle 311, and a limiting protrusion 312 is provided on the upper side of the brush handle 311. The inner wall of the water outlet 106 has a limiting groove 107 corresponding to the limiting protrusion 312 and a support groove corresponding to the support protrusion 313. Under the action of the support protrusion 313, the axis of the brush handle 311 coincides with the axis of the water outlet 106, and a gap is formed between the brush handle 311 and the water outlet 106.

[0075] Optionally, such as Figure 2 As shown, the baffle assembly includes a middle baffle 200 and a top post 210. The middle baffle 200 is movable toward or away from the front side panel 101; the top post 210 is disposed on the middle baffle 200 and corresponds to the water outlet 106, and is used to extend into the water outlet 106 and push against the brush handle 311 so that the brush head 314 extends out of the nozzle 300.

[0076] In this embodiment, the top post 210 moves synchronously with the middle partition 200. The shape of the top post 210 is adapted to the shape of the water outlet 106, and its size is slightly smaller than that of the water outlet 106, so that the top post 210 can be smoothly inserted into the water outlet 106 to push the brush head 314 of the soft brush 310 out of the nozzle 300.

[0077] For example, the front panel 101 has multiple water outlet holes 106 along the axial direction of the cross-flow fan 400, and the surface of the front panel 101 facing the cross-flow fan 400 has nozzles 300 corresponding to each water outlet hole 106. The surface of the middle partition 200 facing the front panel 101 has top posts 210 corresponding to each water outlet hole 106. In this way, when the middle partition 200 moves toward the front panel 101, the multiple top posts 210 move synchronously and insert into the corresponding water outlet holes 106, pushing out the soft brush 310 in each water outlet hole 106 and spraying condensate water onto the fan assembly through the corresponding nozzle 300.

[0078] Optionally, a magnetic block 211 is provided at the abutting end of the top post 210 and the brush handle 311, so that the top post 210 can pull the brush head 314 from outside the nozzle 300 back into the water outlet 106 by magnetic force.

[0079] In this embodiment, when the partition plate 200 moves toward the front side plate 101, the top post 210 extends into the water outlet 106, pushes against the brush handle 311, and ejects the brush head 314 out of the nozzle 300. Simultaneously, the magnetic blocks 211 of the top post 210 and the brush handle 311 attract each other. When the partition plate 200 moves away from the front side plate 101, the top post 210 is pulled out of the water outlet 106 and, under magnetic force, pulls the brush handle 311, causing the brush head 314 to return from outside the nozzle 300 to inside the water outlet 106.

[0080] Optionally, the end of the brush handle 311 facing the top post 210 is provided with a latch, and the end of the top post 210 facing the brush handle 311 is provided with a spring hook. Thus, when the partition plate 200 moves towards the front side plate 101, the top post 210 extends into the water outlet 106, pushes against the brush handle 311, and ejects the brush head 314 from the nozzle 300. Simultaneously, the spring latch of the top post 210 engages with the latch of the brush handle 311. When the partition plate 200 moves away from the front side plate 101, the top post 210 is pulled out of the water outlet 106 and pulls the brush handle 311. When the limiting protrusion 312 of the brush handle 311 moves to the first end of the limiting groove 107, it is blocked by the limiting groove 107. The blocking force is greater than the pulling force of the spring hook, causing the spring hook to automatically release, and the top post 210 and the brush handle 311 separate.

[0081] Optionally, the partition assembly includes a central partition 200 and a telescopic rod 220. The central partition 200 can move toward or away from the front side panel 101; the telescopic end of the telescopic rod 220 is connected to the central partition 200; the telescopic direction of the telescopic rod 220 is parallel to the moving direction of the central partition 200, and the telescopic rod 220 drives the central partition 200 to move when it extends or retracts.

[0082] In this embodiment, when the telescopic rod 220 extends, it moves the partition plate 200 towards the front side plate 101, compressing the spray space 104 so that the condensate inside is sprayed onto the fan assembly through the nozzle 300. When the telescopic rod 220 retracts, it moves the partition plate 200 away from the front side plate 101, the spray space 104 returns to its original state, and the condensate in the water receiving space 105 replenishes the spray space 104. Thus, as the telescopic rod 220 reciprocates, the nozzle 300 continuously sprays water onto the fan assembly.

[0083] For example, the fixed end of the telescopic rod 220 is connected to the driving element 221, and the telescopic end of the telescopic rod 220 is driven to extend and retract via the driving element 221. For instance, the telescopic rod 220 is a hydraulic telescopic rod 220, and the driving element 221 is a hydraulic cylinder, which drives the telescopic end of the telescopic rod 220 to extend and retract. Alternatively, the telescopic rod 220 is a pneumatic telescopic rod 220, and the driving element 221 is a pneumatic cylinder, which drives the telescopic end of the telescopic rod 220 to extend and retract.

[0084] As another example, a telescopic rod 220 is provided at each end and in the middle of the partition 200 along its length. The synchronous extension and retraction of the three telescopic rods 220 drives the partition 200 to move, ensuring the stability of the movement of the partition 200.

[0085] Optionally, the baffle assembly includes a central baffle 200 and a duckbill valve 230. The central baffle 200 is movable toward or away from the front side panel 101; the duckbill valve 230 is disposed within the water spray space 104, and the inlet end of the duckbill valve 230 is connected to the water receiving space 105 through the central baffle 200.

[0086] In this embodiment, a duckbill valve 230 is used so that condensate can only enter the spray space 104 from the water receiving space 105. Thus, when the partition 200 moves towards the front side plate 101, the spray space 104 is compressed, causing the condensate inside to be sprayed onto the fan assembly through the spray brush assembly, reducing the amount of condensate in the spray space 104. When the partition 200 moves away from the front side plate 101, the spray space 104 expands, and the condensate in the water receiving space 105 enters the spray space 104 through the duckbill valve 230, replenishing the condensate in the spray space 104.

[0087] This disclosure also provides an air conditioner, including the indoor unit described in any of the above embodiments.

[0088] Combination Figure 7 As shown, this disclosure provides a control method for an indoor unit, including:

[0089] S01: The controller acquires the water level information of the spray space 104;

[0090] S02: When the water level information is greater than or equal to the preset water level, the controller controls the middle partition 200 to move toward the direction closer to the front side plate 101;

[0091] S03: The controller acquires the position information of the limit protrusion 312;

[0092] S04: When the limiting protrusion 312 moves to the second end of the limiting groove 107 for time t1, the controller controls the middle partition 200 to move away from the front side plate 101.

[0093] S05: Repeat the above steps to make the partition 200 move back and forth.

[0094] In this embodiment, a water level sensor is provided inside the spray space 104, and the controller obtains the water level information of the spray space 104 through the water level sensor. A contact sensor is provided at the second end of the limiting groove 107, and the controller obtains the position information of the limiting protrusion 312 through the contact sensor. t1≥0s. When t1=0s, after the limiting protrusion 312 moves to the second end of the limiting groove 107, the controller immediately controls the middle partition 200 to move away from the front side plate 101. At this time, the brush head 314 extends, brushes briefly, and then retracts. When t1>0s, after the limiting protrusion 312 moves to the second end of the limiting groove 107 and stays for a period of time, the controller then controls the middle partition 200 to move away from the front side plate 101. At this time, the brush head 314 extends, brushes for t1 time, and then retracts. When the controller controls the partition 200 to move toward the front side panel 101, the nozzle 300 sprays water and the brush head 314 extends; when the controller controls the partition 200 to move away from the front side panel 101, the brush head 314 retracts and the water receiving space 105 replenishes water to the spraying space 104.

[0095] Optionally, in step S01, if the water level in the spray space 104 is lower than the preset water level, clean water is added to the water receiving space 105 through the water replenishment channel. The clean water in the water receiving space 105 flows into the spray space 104 through the duckbill valve 230. Steps S02-S05 are then executed until the water level in the spray space 104 equals the preset water level. In this way, the cleaning requirements are met by continuously replenishing water.

[0096] Optionally, in step S02, the controller controls the cross-flow fan 400 to rotate alternately in the forward and reverse directions, so that the water jets sprayed by the nozzle 300 and the brush head 314 can better clean the cross-flow fan 400.

[0097] Optionally, before step S01, the controller closes the air deflector of the indoor unit. This prevents condensate from splashing into the room through the air outlet during cleaning, thus ensuring that the condensate is discharged through the drain channel 411.

[0098] Combination Figure 8 As shown, this disclosure provides another control method for an indoor unit, including:

[0099] S06: The controller acquires the dynamic balance information of the cross-flow fan 400;

[0100] S07: The controller controls the rotation of the cross-flow fan 400 according to the dynamic balance information so that the unbalanced area faces the nozzle 300;

[0101] S08: The controller controls the intermediate partition 200 to reciprocate a preset number of times, and the controller controls the cross-flow fan 400 to rotate alternately in the forward and reverse directions within the imbalance area.

[0102] In this embodiment, the controller obtains the dynamic balance information of the cross-flow fan 400 through a dynamic balance measuring instrument installed in the indoor unit. Here, by reciprocating the movement of the partition 200 and alternating forward and reverse rotation of the cross-flow fan 400 within the imbalance area, water is sprayed and brushed onto the imbalance area, thereby effectively cleaning the dust in the imbalance area. If, after the partition has reciprocated a preset number of times, the cross-flow fan 400 still has an imbalance area, it may not be due to dust accumulation. The controller issues a warning to the user, reminding them to disassemble and inspect the cross-flow fan 400.
