Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a water receiving tray assembly for an air conditioner and an air conditioner. Background Art

[0002] The air conditioner is usually provided with a water collecting pan to receive the condensed water from the evaporator, and a drain outlet is provided on the water collecting pan to discharge the condensed water out of the water collecting pan through the drain outlet. When the drain outlet is not in use, a drain plug is used to block the drain outlet to prevent condensed water from leaking during daily use.

[0003] At present, the drain plug is usually set to an interference fit with the inner wall of the drain hole to achieve the sealing of the drain plug and the drain hole. However, the drain plug and the inner wall of the drain hole only rely on a simple interference fit on the contact surface, and the protection method is single. If the drain plug is immersed in water for a long time, the sealing will deteriorate, causing water leakage.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0040] Embedded air conditioners are usually equipped with a water tray to receive condensed water from the evaporator, and a drain outlet is provided on the water tray to discharge the condensed water out of the water tray through the drain outlet. When the drain outlet is not in use, a drain plug is used to block the drain outlet to prevent condensed water from leaking during daily use.

[0041] At present, the drain plug is usually set to an interference fit with the inner wall of the drain hole to achieve the sealing of the drain plug and the drain hole. However, the drain plug and the inner wall of the drain hole only rely on a simple interference fit on the contact surface, and the protection method is single. If the drain plug is immersed in water for a long time, the sealing will deteriorate, causing water leakage.

[0042] Combination Figure 1-5As shown, an embodiment of the present disclosure provides a water receiving pan assembly for an air conditioner, comprising a water receiving pan 10 and a drain plug 20 .

[0043] The water receiving tray 10 is provided with a drainage hole 11; the drainage plug 20 includes a sealing body 21, which is arranged in the drainage hole 11 to close the drainage hole 11; wherein, along the direction in which the drainage plug 20 is inserted into the drainage hole 11, the cross-sectional areas of the drainage hole 11 and the sealing body 21 are adapted and both decrease.

[0044] With the water receiving pan assembly for air conditioners provided by the embodiment of the present disclosure, along the direction in which the drain plug 20 is inserted into the drain hole 11, the cross-sectional areas of the drain hole 11 and the sealing body 21 are adapted, so that the sealing body 21 can match the drain hole 11, thereby achieving a sealing effect on the drain hole 11. During the process of inserting the drain plug 20 into the drain hole 11, as the cross-sectional areas of the drain hole 11 and the sealing body 21 decrease, the friction between the drain plug 20 and the drain hole 11 increases accordingly, so that the drain plug 20 can be more closely attached to the inner wall surface of the drain hole 11 during the insertion process, thereby enhancing the stability of the drain plug 20 and improving the sealing performance of the water receiving pan assembly.

[0045] Optionally, combined Figure 1 and Figure 5 As shown, along the direction in which the drain plug 20 is inserted into the drain hole 11, the cross-sectional areas of the drain hole 11 and the sealing body 21 are gradually reduced.

[0046] The direction in which the drain plug 20 is inserted into the drain hole 11 is as follows: Figure 5 shown.

[0047] Along the direction of the drain plug 20 being inserted into the drain hole 11, the cross-sectional areas of the drain hole 11 and the sealing body 21 are gradually reduced, so that the drain hole 11 and the sealing body 21 both form a tapered structure. During the process of the drain plug 20 being inserted into the drain hole 11, the contact pressure between the drain plug 20 and the drain hole 11 is gradually increased, thereby achieving progressive seal enhancement, and achieving a more uniform stress distribution when the drain plug 20 contacts the drain hole 11. At the same time, the stability of the drain plug 20 can also be improved.

[0048] Optionally, combined Figure 1 and Figure 5 As shown, the inner wall surface of the drain hole 11 is provided with an internal thread 111, and the outer wall surface of the sealing body 21 is provided with an external thread 211 adapted to the internal thread 111, so that the sealing body 21 is threadedly connected to the drain hole 11; wherein, the pitch of the internal thread 111 is equal to its thread width, and / or, the pitch of the external thread 211 is equal to its thread width.

[0049] By providing an internal thread 111 on the inner wall of the drain hole 11 and providing a matching external thread 211 on the outer wall of the sealing body 21, a threaded connection between the sealing body 21 and the drain hole 11 is achieved, which can improve the connection stability between the drain plug 20 and the drain hole 11. The screw thread is fixed by rotation, which saves time and effort, making the installation and disassembly of the drain plug 20 more convenient. At the same time, the spiral structure of the thread has a natural guiding property, so that the sealing body 21 can be accurately screwed into the external thread 211 along the internal thread 111, and precise positioning can be achieved, and the direction in which the drain plug 20 is inserted into the drain hole 11 can be limited. The contact surface between the internal thread 111 and the external thread 211 is larger than the contact surface between the other structures of the drain plug 20 and the drain hole 11. The close fit between the internal thread 111 and the external thread 211 can also increase the sealing performance, prevent the drain plug 20 from falling off, and improve the anti-leakage effect.

[0050] The pitch of the external thread 211 is as follows Figure 5 As shown in P1, the thread width of the external thread 211 is as follows Figure 5 As shown in P2.

[0051] The pitch of the external thread 211 is equal to the thread width of the external thread 211, so that the number of turns of the external thread 211 increases, the distribution of the external thread 211 is more compact, and the inclination angle between the multiple external threads 211 is reduced, which can increase the friction of the external thread 211, thereby increasing the self-locking property of the drain plug 20. The pitch of the internal thread 111 is equal to the thread width of the internal thread 111, which can also increase the friction of the internal thread 111, thereby improving the locking effect of the internal thread 111 on the external thread 211. When the external thread 211 of the sealing body 21 and the internal thread 111 of the drain hole 11 are screwed together, the external thread 211 and the internal thread 111 can be more closely matched, reducing the gap at the threaded connection, further improving the sealing performance, and preventing moisture penetration.

[0052] Optionally, combined Figure 1 and Figure 3 As shown, the surface of the sealing body 21 includes a first surface 212 and a second surface 213; the second surface 213 is arranged opposite to the first surface 212, and along the direction in which the drain plug 20 is inserted into the drain hole 11, the first surface 212 and the second surface 213 are arranged in sequence, and the second surface 213 is inclined toward the direction close to the axis of the sealing body 21.

[0053] Along the direction in which the drain plug 20 is inserted into the drain hole 11, the first surface 212 and the second surface 213 are sequentially arranged, and the second surface 213 is inclined toward the direction close to the axis of the sealing body 21, so that the second surface 213 forms a guide surface. When the drain plug 20 is inserted into the drain hole 11, the second surface 213 provides a path guide for the drain plug 20, guides the sealing body 21 to be smoothly inserted into the drain hole 11, reduces the resistance during insertion, and thus can improve the installation efficiency and accuracy.

[0054] Optionally, combined Figure 5 As shown, the sealing body 21 is provided with a cavity 214 .

[0055] The cavity 214 can form a buffer space in the sealing body 21. When the drain plug 20 is installed into the drain hole 11, the sealing body 21 is compressed and contracted, and the excess stress is released in the cavity 214, which can reduce the direct impact on the sealing body 21 and prevent the sealing body 21 from being damaged when subjected to external force. When removing the drain plug 20, it is also possible to insert a tool into the cavity 214 to more easily grasp or pry the drain plug 20, thereby improving the convenience of removing the drain plug 20.

[0056] Optionally, combined Figure 1-3 and Figure 5 As shown, the drain plug 20 further includes a sealing edge 22 , which is connected to the sealing body 21 and is located outside the drain hole 11 , and the sealing edge 22 is in contact with the water receiving tray 10 .

[0057] The sealing edge 22 is connected to the sealing body 21 and is located on the outside of the drain hole 11, and the sealing edge 22 is in contact with the water receiving tray 10. There is friction between the sealing edge 22 and the water receiving tray 10, so that a sealing layer is formed between the sealing edge 22 and the water receiving tray 10, preventing water from leaking from the gap between the water receiving tray 10 and the drain plug 20, thereby improving the sealing performance of the water receiving tray assembly.

[0058] The sealing edge 22 is located outside the drain hole 11 and does not directly contact the water in the water receiving tray 10. When the drain plug 20 is immersed in water for a long time, the friction between the sealing edge 22 and the water receiving tray 10 can still play a sealing role, and can prevent water leakage caused by loosening of the sealing body 21.

[0059] The sealing edge 22 fits the water receiving tray 10 , forming a protective barrier for the drainage hole 11 at the outside of the drainage hole 11 , and can also prevent external pollutants such as dust and impurities from entering the drainage hole 11 .

[0060] Optionally, combined Figure 2-3 As shown, the sealing edge 22 is annular and extends along the circumference of the drainage hole 11 .

[0061] The sealing edge 22 is in a ring shape extending along the circumference of the drain hole 11, so that the sealing edge 22 can fully fit with the water receiving tray 10 along the circumference of the drain hole 11, thereby enhancing the sealing of the drain plug 20 to the drain hole 11 and reducing the risk of water leakage.

[0062] Optionally, the sealing edge 22 is interference fit with the water receiving tray 10 .

[0063] The interference fit between the sealing edge 22 and the water receiving tray 10 enables the sealing edge 22 to be in close contact with the water receiving tray 10, which can enhance the sealing effect. When water leaks from between the sealing body 21 and the drain hole 11, the interference fit surface can prevent the leakage of condensed water and improve the overall structural stability of the water receiving tray assembly.

[0064] For example, when the drain plug 20 is installed in the water receiving tray 10, the sealing body 21 is first aligned with the drain hole 11, and the sealing body 21 is inserted into the drain hole 11 under the guidance of the second surface 213 of the sealing body 21. Then the drain plug 20 is rotated so that the external thread 211 of the sealing body 21 is screwed with the internal thread 111 of the drain hole 11 to achieve self-locking of the threads. When the sealing edge 22 is in contact with the outer surface of the water receiving tray 10, the drain plug 20 is continued to be rotated so that the sealing edge 22 and the water receiving tray 10 are interference fit. At this time, the friction between the sealing edge 22 and the outer surface of the water receiving tray 10 increases, thereby playing a sealing role, so that the drain plug 20 has a dual waterproof effect.

[0065] Optionally, combined Figure 2-3 As shown, a concave-convex structure 30 is provided on at least one of the surface of the water receiving tray 10 for contacting with the sealing edge 22 and the sealing edge 22 .

[0066] The surface of the water receiving tray 10 that abuts against the sealing edge 22 may be provided with a concavo-convex structure 30 , or the sealing edge 22 may be provided with a concavo-convex structure 30 , or both the surface of the water receiving tray 10 that abuts against the sealing edge 22 and the sealing edge 22 may be provided with a concavo-convex structure 30 .

[0067] The concavo-convex structure 30 can increase the roughness of the surface of the water receiving tray 10 for contacting with the sealing edge 22 and / or the sealing edge 22. When the surface of the water receiving tray 10 contacts with the sealing edge 22, the concavo-convex structure 30 can generate greater friction and play a locking role, so that the drain plug 20 is more firmly fixed on the water receiving tray 10, preventing the drain plug 20 from shifting or loosening from the drain hole 11. The concavo-convex structure 30 and the surface of the water receiving tray 10 are closely matched and can effectively block moisture, so that no moisture will leak out of the drain hole 11 when it is closed, thereby improving the sealing performance of the water receiving tray assembly.

[0068] When the surface on the water receiving tray 10 for abutting against the sealing edge 22 and the sealing edge 22 are both provided with a concave-convex structure 30, the concave-convex structure 30 of the sealing edge 22 and the concave-convex structure 30 on the surface of the water receiving tray 10 are interlocked to form a tight fit, which can improve the locking stability of the sealing edge 22 and improve the sealing performance of the drain plug 20 to the water receiving tray 10.

[0069] Optionally, combined Figure 2-3 As shown, the concave-convex structure of the sealing edge 22 includes an inclined surface 31, which is suitable for abutting against the surface of the water receiving tray 10 to limit the movement of the sealing body 21 in the direction of disconnection from the drain hole 11, wherein along the direction from disconnection to connection between the sealing body 21 and the drain hole 11, the inclined surface 31 is inclined in the direction away from the drain hole 11.

[0070] The sealing body 21 and the drain hole 11 are connected from the direction of disconnection to connection. Figure 3 shown.

[0071] The inclined surface 31 can change the contact angle between the sealing edge 22 and the surface of the water receiving tray 10 , thereby increasing the friction between the sealing edge 22 and the surface of the water receiving tray 10 , and preventing the sealing body 21 from moving in the direction of disconnecting from the drainage hole 11 .

[0072] Along the direction from the sealing body 21 and the drain hole 11 being disconnected to being connected, the inclined surface 31 is inclined in the direction away from the drain hole 11. When the sealing body 21 attempts to escape in the direction of disconnecting from the drain hole 11, the sealing body 21 must overcome the resistance generated by the inclined surface 31 to be disconnected from the drain hole 11. The provision of the inclined surface 31 can enhance the locking effect, making the connection between the sealing body 21 and the drain hole 11 more stable, thereby improving the firmness of the locking of the drain plug 20.

[0073] Optionally, combined Figure 2-3 As shown, the sealing edge 22 is provided with a plurality of inclined surfaces 31 , and the plurality of inclined surfaces 31 are sequentially arranged along the circumference of the sealing edge 22 .

[0074] The setting of multiple inclined surfaces 31 allows for more locking contact points between the sealing edge 22 and the surface of the water receiving tray 10. Multiple inclined surfaces 31 are arranged in sequence along the circumference of the sealing edge 22, and each inclined surface 31 contacts the surface of the water receiving tray 10 in sequence, gradually increasing the locking force and being able to provide all-round locking along the circumference of the sealing edge 22, thereby achieving a more secure locking.

[0075] The multiple inclined surfaces 31 are all inclined in a direction away from the drain hole 11, forming a sealing edge 22 that allows only one-way rotation. When the sealing body 21 attempts to move in a direction to release the connection with the drain hole 11, it will encounter resistance from the multiple inclined surfaces 31, which can enhance the locking effect between the sealing edge 22 and the water receiving tray 10, thereby enhancing the sealing performance of the drain plug 20.

[0076] At the same time, the surface of the water receiving tray 10 can contact each inclined surface 31 in sequence, so that the force between the water receiving tray 10 and the sealing edge 22 is evenly distributed, reducing local stress concentration and improving overall stability and durability.

[0077] Optionally, combined Figure 2-3 As shown, the inclined surfaces 31 are sequentially arranged along the circumference of the sealing edge 22 , triangular protrusions are formed between adjacent inclined surfaces 31 , and a plurality of triangular protrusions are sequentially arranged along the circumference of the sealing edge 22 to form a ratchet structure.

[0078] The ratchet structure only allows one-way rotation, which can improve the self-locking performance of the sealing edge 22. The inclined surface 31 is the chamfered part of the ratchet structure, and the corner of the triangular protrusion is the barb part of the ratchet structure. When the sealing body 21 rotates into the drain hole 11, the chamfered part makes the pre-tightening process of the sealing edge 22 easier, so that the sealing edge 22 and the water receiving tray 10 are self-locking. After the pre-tightening is completed, under the action of the barb part, the drain plug 20 enters a self-locking state, which can prevent the seal from loosening and improve the sealing effect of the drain plug 20.

[0079] Optionally, the concavo-convex structure 30 disposed on the surface of the water receiving tray 10 abutting against the sealing edge 22 is provided by a leather grain processing process.

[0080] The leather grain treatment can form a microscopic concave-convex texture on the surface where the water receiving tray 10 and the sealing edge 22 abut, increase the friction coefficient of the surface of the concave-convex structure 30, and improve the gripping force between the sealing edge 22 and the surface of the water receiving tray 10. The leather grain treated concave-convex structure 30 can fit more closely with the sealing edge 22, and improve the locking stability of the drain plug 20.

[0081] When the sealing edge 22 is a ratchet structure and the surface of the water receiving tray 10 that contacts the sealing edge 22 is treated with leather grain, the friction between the sealing edge 22 and the water receiving tray 10 can be increased. The ratchet structure of the sealing edge 22 is locked by the inclined surface 31 (equivalent to the ratchet) and the leather grain concave-convex structure 30 (equivalent to the ratchet) that matches it. At this time, the ratchet structure and the leather grain concave-convex structure 30 are in line contact, and the highest point of the ratchet concave-convex structure 30 will be stuck in the leather grain concave-convex structure 30, thereby playing a self-locking role. When the sealing body 21 of the drain plug 20 is screwed into the drain hole 11, the ratchet passes over the ratchet and is stuck by the ratchet, thereby achieving one-way locking of the drain plug 20. When the drain plug 20 is not subjected to external force, its own gravity will not be able to offset the friction of the ratchet structure, which can prevent the drain plug 20 from loosening.

[0082] Optionally, combined Figure 5 As shown, the drain plug 20 also includes a connecting portion 23, which is connected between the sealing body 21 and the sealing edge 22, and the connection between the connecting portion 23 and the sealing body 21 and the connection between the connecting portion 23 and the sealing edge 22 are both bent; wherein the connecting portion 23 is provided with an avoidance groove 231 for avoiding the water receiving tray 10.

[0083] The connection part 23 connects the sealing body 21 and the sealing edge 22, and bends are formed at the connection between the connection part 23 and the sealing body 21 and the connection between the connection part 23 and the sealing edge 22, which can enhance the structural strength of the drain plug 20 and improve the stability and durability of the drain plug 20. At the same time, the avoidance groove 231 provided in the connection part 23 can reduce the area of ​​the sealing edge 22, enhance the deformation ability of the sealing edge 22, and thus reduce the rigidity of the sealing edge 22. When the sealing edge 22 and the water receiving tray 10 are interference fit, the avoidance groove 231 can avoid the water receiving tray 10, and can also provide a certain deformation space for the deformation of the sealing edge 22, so that the sealing edge 22 and the water receiving tray 10 fit more closely.

[0084] Optionally, combined Figure 1-2 and Figure 5 As shown, the drain plug 20 further includes a handle 40 , which is disposed on a side of the sealing edge 22 facing away from the sealing body 21 .

[0085] The sealing edge 22 is suitable for being arranged outside the drain hole 11, and the handle 40 is arranged on the side of the sealing edge 22 away from the sealing body 21, which can provide an easy-to-grip position. By grasping the handle 40, a power assist is formed, making the installation and disassembly of the drain plug 20 more convenient.

[0086] Combination Figure 4 As shown, an embodiment of the present disclosure provides an air conditioner, including an indoor unit 50, the indoor unit 50 includes an evaporator and a water receiving tray assembly as described in any one of the above embodiments, and the water receiving tray assembly is arranged below the evaporator to receive condensed water generated by the evaporator.
