Description

Technical Field

[0001] This application relates to the field of air-cooled cabinet technology, and in particular to an automatically cleaning water tray device and an air conditioning indoor unit. Background Technology

[0002] During daily use, air conditioning units carry airborne pollutants to the evaporator fins. In cooling mode, the condensate washes these pollutants away, allowing them to drain into the drip tray. Over time, these pollutants settle and adhere to the bottom of the drip tray. When a certain amount accumulates, it obstructs condensate drainage, causing condensate to leak from the edge of the drip tray, resulting in air conditioner leaks. To address this issue and ensure timely cleaning of the drip tray, a structure has been designed to automatically clean the drip tray, allowing for smooth condensate drainage and preventing leaks.

[0045] As mentioned in the background section, in order to solve the technical problem that dirt easily accumulates in the drip tray of the air conditioner indoor unit in the prior art, affecting the flow of condensate, this application provides an automatically cleanable drip tray device and air conditioner indoor unit equipment, which can clean the dirt in the drip tray, so that the dirt is discharged with the condensate and avoids the blockage of the drain trough 11.

[0046] Example 1

[0047] This embodiment provides an automatically cleanable water tray device, comprising:

[0048] The water receiving tray body 1 has a drainage groove 11 and a drainage outlet 12. The drainage groove 11 extends along the first direction and is connected to the external environment through the drainage outlet 12.

[0049] Cleaning blades 3, multiple cleaning blades 3 are distributed in the drainage trough 11 along the first direction. The cleaning blades 3 have a rotating end, and the cleaning blades 3 can rotate around the rotating end. The rotation axis extends along the second direction, which is perpendicular to the first direction.

[0050] The drive mechanism 4 is located on the water receiving tray body 1 and is connected to multiple cleaning blades 3 in a transmission manner. The drive mechanism 4 is used to synchronously drive multiple cleaning blades 3 to rotate around their respective rotation axes so that one end of the cleaning blade 3 along the second direction slides into contact with the bottom of the drainage trough 11.

[0051] like Figure 1 and Figure 2 As shown, the first direction is the length direction of the indoor unit of the air conditioner, and the second direction is the vertical direction. The water receiving tray is installed inside the indoor unit of the air conditioner, located below the evaporator 5. It is mainly used to collect the condensate produced by the evaporator 5 during operation. The condensate drips onto the water receiving tray body 1, is collected by the drain trough 11, and is discharged through the drain outlet 12. When the indoor unit of the air conditioner is working, dust and impurities suspended in the air will be adsorbed onto the evaporator 5. The condensate produced on the evaporator 5 will then wash the dust and impurities into the drain trough 11. During the discharge of condensate, some dust and impurities will settle to the bottom of the drain trough 11. After a certain period of accumulation, the dirt adsorbed at the bottom of the drain trough 11 will seriously affect the discharge of condensate. The drain trough 11 is approximately a cuboid groove, and the drain outlet 12 is located at one end of its extension direction. The drain outlet 12 connects the inside and outside of the indoor unit of the air conditioner. The cleaning blades 3 are approximately rectangular flat structures. Multiple cleaning blades 3 are evenly spaced in the drainage trough 11 along the first direction. The bottom of the cleaning blades 3 abuts against the bottom of the drainage trough 11, and each blade can rotate around its own rotating end. During rotation, the bottom of the cleaning blades 3 slides into contact with the bottom of the drainage trough 11, thereby scraping off the dirt attached to the bottom of the drainage trough 11, separating the dirt from the drainage trough 11, and allowing it to be discharged with the condensate. The drive mechanism 4 is located on the water receiving tray body 1 and is connected to the multiple cleaning blades 3. The drive mechanism 4 can synchronously drive the multiple cleaning blades 3 to rotate around their respective rotation axes toward the side closer to the drain outlet 12 or away from the drain outlet 12. By driving the cleaning blades 3 to reciprocate around the rotation axis, the contact area between the cleaning blades 3 and the drainage trough 11 during rotation can be made fan-shaped, thereby maximizing the cleaning effect.

[0052] By setting multiple rotatable cleaning blades 3 in the drain trough 11, and using a drive mechanism 4 to synchronously drive the multiple cleaning blades 3 to rotate around their respective rotation axes, the cleaning blades 3 slide into contact with the bottom of the drain trough 11 at one end along the second direction. As the cleaning blades 3 reciprocate within the drain trough 11, the dirt that has settled or adhered to the bottom of the drain trough 11 falls off under the action of the cleaning blades 3. The fallen dirt can flow along with the condensate in the drain trough 11 and be discharged from the drain outlet 12, thereby preventing dirt from clogging the drain trough 11 and causing air conditioner leakage.

[0053] In a preferred embodiment, the water receiving tray body 1 is provided with a support structure 2, the support structure 2 including:

[0054] Support plate 21 covers the drainage trough 11;

[0055] The connecting plate 22 is fixed on the side of the support plate 21 near the drainage trough 11, and the rotating ends of the multiple cleaning blades 3 are rotatably connected to the connecting plate 22.

[0056] like Figure 1 and Figure 7 As shown, the support plate 21 is a long strip structure extending along the first direction. The support plate 21 is fixed at the opening of the drain trough 11 and located below the evaporator 5 to support the evaporator 5. The connecting plate 22 is also a long strip structure extending along the first direction, and the connecting plate 22 is integrally formed on the support plate 21. The connecting plate 22 is located on the side of the support plate 21 near the drain trough 11 and can support the support plate 21. The connecting plate 22 is rotatably connected to the rotating ends of multiple cleaning blades 3, so that the cleaning blades 3 can rotate on the connecting plate 22.

[0057] In a preferred embodiment,

[0058] The connecting plate 22 has multiple connecting holes along the first direction. The number of connecting holes corresponds to the number of cleaning blades 3. A rotating shaft 214 is provided in the connecting hole and extends along the second direction.

[0059] A first slot 31 is provided on the rotating end, and the rotating end extends into the connecting hole so that the first slot 31 is fitted around the outer circumference of the rotating shaft 214, thereby allowing the cleaning blade 3 to be rotatably connected to the connecting plate 22.

[0060] like Figure 5-8As shown, the connecting holes are approximately rectangular and are evenly spaced along the first direction on the connecting plate 22. Each connecting hole corresponds to a cleaning blade 3. A rotating shaft 214 is provided within each connecting hole, and the rotating shaft 214 is arranged vertically. Two claws are located on the rotating end of the cleaning blade 3. The two claws together form the aforementioned first groove 31. The internal contour of the first groove 31 matches the external contour of the rotating shaft 214. The two claws are elastic and can move away from or closer to each other under external force, thereby expanding or shrinking the opening of the first groove 31 and engaging the two claws. The two claws are inserted into the connecting hole, and their free ends abut against the rotating shaft 214. This pushes the cleaning blade 3, causing the two claws to move away from each other under the action of the rotating shaft 214. As a result, the opening of the first slot 31 expands, and the rotating shaft 214 is embedded in the first slot 31. The cleaning blade 3 can then rotate smoothly around the central axis of the rotating shaft 214. By setting two claws on the rotating end of the cleaning blade 3 to form the first slot 31, the cleaning blade 3 and the connecting plate 22 form a detachable and quick-assembly structure, which is convenient for assembly and also facilitates the disassembly and replacement of the cleaning blade 3.

[0061] In a preferred embodiment, the drive mechanism 4 includes:

[0062] A drive motor is mounted on the water receiving tray body 1 and located on the side of the drainage trough 11 away from the drain outlet 12; a first connecting rod 41 is fixed on the drive shaft of the drive motor, and a second connecting rod 42 is rotatably connected to the free end of the first connecting rod 41.

[0063] The transmission rod 43 extends in the drainage trough 11 along the first direction. One end of the transmission rod 43 is rotatably connected to the end of the second connecting rod 42 away from the first connecting rod 41. The transmission rod 43 is rotatably connected to multiple cleaning blades 3 respectively.

[0064] like Figure 5As shown, the drive motor can be a stepper motor as in the prior art. The drive motor is located on the side of the drainage trough 11 away from the drain outlet 12, which can effectively prevent condensation from affecting the normal operation of the drive motor. The drive shaft of the drive motor extends vertically, and the first connecting rod 41 is set horizontally and sleeved and fixed on the drive shaft of the drive motor. One end of the second connecting rod 42 is rotatably connected to the free end of the first connecting rod 41, and the other end of the second connecting rod 42 is rotatably connected to the transmission rod 43. The transmission rod 43 is set in the drainage trough 11 along the first direction, located below the support plate 21 and on one side of the connecting plate 22. The transmission rod 43 is rotatably connected to multiple sweeping blades 3 at the same time. When the drive motor is started, the drive motor drives the first connecting rod 41 to rotate around the axis of the drive shaft, which in turn drives the connection end of the second connecting rod 42 and the first connecting rod 41 to rotate around the axis of the drive shaft. As the shaft rotates, the transmission rod 43 is simultaneously rotatably connected to multiple cleaning blades 3. Under the action of the second connecting rod 42, the transmission rod 43 reciprocates relative to the drainage trough 11 in the first direction. When the transmission rod 43 moves towards the drive motor, multiple cleaning blades 3 simultaneously rotate around their respective rotation axes towards the drive motor, and the bottom of the cleaning blades 3 forms a fan-shaped contact area with the bottom of the drainage trough 11. When the transmission rod 43 moves away from the drive motor, multiple cleaning blades 3 simultaneously rotate around their respective rotation axes away from the drive motor, and the bottom of the cleaning blades 3 forms a fan-shaped contact area with the bottom of the drainage trough 11. The contact areas of the bottom of each cleaning blade 3 and the bottom of the drainage trough 11 overlap, so that the cleaning area of ​​the cleaning blades 3 covers the bottom of the drainage trough 11 as much as possible.

[0065] Furthermore, the cleaning blade 3 can rotate to the first working position when driven by the transmission rod 43, and can rotate to the second working position when driven by the transmission rod 43, with the angle between the first working position and the second working position being an obtuse angle. At the same time, when the cleaning blade 3 is not working, it stops at the first working position or the second working position to avoid affecting the flow of condensate in the drainage tank 11.

[0066] In a preferred embodiment,

[0067] The transmission rod 43 is provided with multiple locking blocks 431, and the number of locking blocks 431 corresponds to the number of cleaning blades 3;

[0068] A through hole 32 is provided on the side of the cleaning blade 3 away from the drainage groove 11. The snap-fit ​​block 431 extends into the through hole 32 so that the cleaning blade 3 is rotatably connected to the transmission rod 43.

[0069] like Figure 5 and Figure 6As shown, the locking blocks 431 are evenly spaced on the transmission rod 43 along the first direction. The number of locking blocks 431 corresponds to the number of cleaning blades 3. Each locking block 431 includes a first part and a second part. The first part and the second part are elastic and have a gap between them. They can move away from or towards each other under the action of external force, thereby expanding or shrinking the gap. The free ends of the first part and the second part also have limiting parts. The through hole 32 is opened on the side of the cleaning blade 3 away from the drainage groove 11. When the locking block 431 is pressed against one end of the through hole 32 and pushed, the limiting parts of the first part and the second part are controlled by the through hole 32. When they approach each other, and the gap disappears, the limiting part of the first part and the limiting part of the second part can pass through the through hole 32 together. After passing through the through hole 32, the force disappears, and the first part and the second part of the locking block 431 move away from each other. The limiting part of the first part and the limiting part of the second part abut against the other end of the through hole 32, so that each cleaning blade 3 and the transmission rod 43 are relatively fixed in the second direction. At the same time, the cleaning blade 3 and the transmission rod 43 are rotatably connected. By setting the elastic locking block 431 with the first part and the second part on the transmission rod 43, the cleaning blade 3 and the transmission rod 43 form a detachable quick assembly structure, which is convenient for assembly and also convenient for disassembly and replacement.

[0070] In a preferred embodiment, there is a first distance between two adjacent rotating shafts 214 and a second distance between two adjacent snap-fit ​​blocks 431, and the first distance and the second distance are equal.

[0071] like Figure 5 As shown, by making the distribution positions of each rotating shaft 214 on the connecting plate 22 correspond one-to-one with the distribution positions of each snap-fit ​​block 431 on the transmission rod 43, each cleaning blade 3 can rotate synchronously around the rotating shaft 214 under the drive of the transmission rod 43, thus avoiding motion interference between the cleaning blades 3 during rotation.

[0072] In a preferred embodiment, the support plate 21 has a plurality of strip holes 211.

[0073] like Figure 7 As shown, multiple strip holes 211 are opened on the support plate 21 corresponding to the drainage groove 11, so that the condensate generated by the evaporator 5 above the support plate 21 can enter the drainage groove 11 through the strip holes 211. The number of strip holes 211 can be set according to the actual situation. As long as the condensate generated on the evaporator 5 can enter the drainage groove 11 smoothly, the number of strip holes 211 does not affect the overall structural strength of the support plate 21, and no special limitation is made here.

[0074] In a preferred embodiment, the water receiving tray body 1 is provided with a first positioning structure, and the support plate 21 is provided with a second positioning structure corresponding to the first positioning structure, and the first positioning structure and the second positioning structure are engaged.

[0075] like Figure 3 , Figure 4 and Figure 7 As shown, the first positioning structure includes positioning grooves 13 and positioning protrusions 14. Multiple positioning grooves 13 are formed along a first direction at one end of the width direction of the water receiving tray body 1, and multiple positioning protrusions 14 are formed along the first direction at the other end of the width direction of the water receiving tray body 1. The second positioning structure includes positioning blocks 212 and positioning ribs 213. Multiple positioning blocks 212 are corresponding to the positioning grooves 13 and are formed along the first direction at one end of the width direction of the support plate 21. Multiple sets of positioning ribs 213 are corresponding to the positioning protrusions 14 and are formed along the first direction at the other end of the width direction of the support plate 21. Each set of positioning ribs 213 consists of two ribs, and a positioning groove is formed between the two positioning ribs 213 in each set. The inner contour of the positioning groove 13 matches the outer contour of the positioning block 212, and the inner contour of the positioning groove matches the outer contour of the positioning protrusion 14. When installing the support plate 21, one end of the support plate 21 with the positioning block 212 is brought into contact with one end of the water receiving tray body 1 with the positioning groove 13, so that each positioning block 212 is embedded into the positioning groove 13 respectively. Then, the other end of the support plate 21 is lowered, so that each set of positioning ribs 213 is in contact with each positioning protrusion 14. Pressing the support plate 21 can make the positioning protrusion 14 embedded into the positioning slot, thereby fixing the support plate 21 and the water receiving tray body 1 relatively. Furthermore, one end of the water receiving tray body 1 in the width direction is provided with multiple threaded holes along the first direction, and the support plate 21 is provided with multiple screw holes corresponding to each threaded hole. By threading the screw through the screw hole and connecting it with the threaded hole on the water receiving tray body 1, the connection structure between the water receiving tray body 1 and the support plate 21 can be further reinforced.

[0076] In a preferred embodiment, a motor base 44 is fixed on the water receiving tray body 1, and a sealing cover 45 is provided on the motor base 44. The motor base 44 and the sealing cover 45 together form a first space, and a drive motor is provided in the first space.

[0077] like Figure 5 As shown, the motor base 44 is similar to a cover structure. Mounting plates are also provided on both sides of the motor base 44. The two mounting plates can also be fixed to the water receiving tray body 1 by screws. The motor base 44 has an opening at one end along the first direction and has the aforementioned first space inside. The first space is used to install the drive motor. The drive shaft of the drive motor passes through the end of the motor base 44 away from the opening and is fixedly connected to the first connecting rod 41. The sealing cover 45 can cover the opening to seal the first space, thereby preventing the condensate generated by the evaporator 5 above from dripping onto the drive motor and causing damage to the drive motor.

[0078] Working principle: During use, the drive motor is started. The drive shaft of the drive motor drives the first connecting rod 41 to rotate around the axis of the drive shaft, causing the connecting end of the second connecting rod 42 to also rotate around the axis of the drive shaft. At this time, the transmission rod 43 moves reciprocally relative to the drainage trough 11 in the first direction under the action of the second connecting rod 42. When the transmission rod 43 moves towards the drive motor, multiple cleaning blades 3 simultaneously rotate around their respective rotation axes towards the drive motor. The bottom of the cleaning blades 3 slides into contact with the bottom of the drainage trough 11, forming a fan-shaped cleaning area. When the transmission rod 43 moves away from the drive motor... Multiple cleaning blades 3 rotate simultaneously around their respective rotation axes toward the side away from the drive motor. The bottom of the cleaning blades 3 slides into contact with the bottom of the drain trough 11 and forms a fan-shaped cleaning area. By rotating back and forth in the drain trough 11, the dirt attached to the bottom of the drain trough 11 can be scraped off, allowing the dirt to detach from the drain trough 11. When the drive motor stops, each cleaning blade 3 stops at the first working position or the second working position. The condensate generated on the evaporator 5 flows into the drain trough 11 through the strip hole 211 on the support plate 21, and carries the dirt in the drain trough 11 out through the drain outlet 12 to the outside of the air conditioner indoor unit.

[0079] Example 2

[0080] This embodiment provides an air conditioning indoor unit device, including an automatically cleanable water tray device as described in Embodiment 1.

[0081] like Figure 9 and Figure 10 As shown, the indoor unit of the air conditioner includes a main body 6, a panel 7 on one side of the main body 6, an evaporator 5 inside the main body 6, a water receiving tray device below the evaporator 5, the water receiving tray device being fixed on the main body 6, a drain trough 11 being opened below the evaporator 5 and communicating with the external environment of the main body 6 through a drain outlet 12, a support plate 21 being located between the drain trough 11 and the evaporator 5, the condensate produced by the evaporator 5 being able to enter the drain trough 11 through the strip hole 211 on the support plate 21, multiple cleaning blades 3 being rotatably connected to a connecting plate 22 integrally formed with the support plate 21, a drive mechanism 4 being located at the end of the drain trough 11 away from the drain outlet 12, for synchronously driving each cleaning blade 3 to reciprocate within the drain trough 11 to clean the dirt attached to the bottom of the drain trough 11, so that the cleaned dirt can be discharged to the outside of the main body 6 along with the condensate through the drain outlet 12.
