Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, specifically relating to an air conditioning indoor and outdoor unit connecting pipe assembly. Background Technology

[0002] In air conditioning systems, the drain pipe is used to drain condensate and contaminants from the drip tray; the connecting pipe connects the indoor and outdoor units for heat exchange. Like other plastic household items, the air conditioner drain pipe gradually becomes brittle and ages over time. Exposed to the air and constantly exposed to wind and sun, and continuously transporting condensate, the pipe walls eventually thin and crack. For example, in some households where the air conditioner has been used for a long time, eight to ten years, aging drain pipes are prone to aging. Secondly, the operating environment is also crucial. If the air conditioner is installed in a high-temperature, humid environment or in the presence of corrosive gases, the aging rate of the drain pipe will accelerate significantly. An aging air conditioner drain pipe may cause leaks, dripping, and odor backflow. Replacing the drain pipe is a common repair method. Usually, the drain pipe is installed with the connecting fittings, and replacing it separately requires disassembling the indoor unit's outer casing, a cumbersome operation that can easily damage the air conditioner. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the background art mentioned above, and to provide an air conditioner indoor and outdoor unit connecting pipe assembly, which fixes the pipe and drain pipe inside through the flow guide shell, isolates sunlight and rainwater to slow down the aging process, and extends the service life of the pipe and drain pipe.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an air conditioner indoor and outdoor unit connecting pipe assembly, comprising a flow guide shell accommodating a copper pipe and a drain pipe, and a connector. The flow guide shell consists of a cover plate and an arc-shaped shell. The arc-shaped shell is C-shaped, with snap-fit ​​seats installed on both ends of the opening. A snap-fit ​​connector is provided on the bottom of the cover plate, allowing the cover plate and the arc-shaped shell to be locked together vertically and horizontally. The connection between the flow guide shell and the flow guide shell or the corrugated pipe is fixedly connected by a connector. The connector includes an annular clamp that fits against the outer wall of the arc-shaped shell and connecting screws. The two ends of the annular clamp are fastened to the snap-fit ​​seats by the connecting screws. A spiral groove is also provided on the inner wall of the annular clamp. The cross-section of the spiral groove is trapezoidal, which engages with the outer wall of the corrugated pipe, limiting the corrugated pipe within the annular clamp.

[0005] Furthermore, the card holder has a sliding groove, and the card connector is a cylindrical part that slides laterally with the sliding groove.

[0006] Furthermore, the end of the card connector is also provided with a ball head, the diameter of which is larger than the diameter of the card connector, and the bottom of the corresponding sliding groove is also provided with a circular groove hole to accommodate the ball head.

[0007] Furthermore, the inner wall of the arc-shaped shell is provided with equally spaced extensions and recesses at its left and right ends, respectively. When two adjacent arc-shaped shells are connected, the extension of the former is inserted into the recess of the latter.

[0008] Furthermore, the cover plate is made of flat plate or arc plate.

[0009] The beneficial effects of this utility model are: 1) This utility model hides the air conditioner's drain pipe and connecting copper pipe through the guide shell and connector, which can avoid direct sunlight and high-temperature corrosion from rainwater, and slow down the aging process of the drain pipe. The connector can connect the corrugated pipe behind the guide shell, which is convenient for pipe routing at bends. The trapezoidal slot in the connector is spirally connected to the corrugated pipe, which limits the corrugated pipe along the axial direction. At the same time, the trapezoidal slot can accommodate the tape that seals the gap of the guide shell, improving the sealing performance. The guide shell is inserted in the direction of drainage and forms a whole through the connector. Even if the drain pipe ages, it can still be discharged outward along the inside of the guide shell, serving as a temporary drainage pipe, which provides convenience for replacing the drain pipe and is simple in structure and easy to use.

[0017] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0018] Example: Figure 1-6As shown, the present invention discloses an air conditioner indoor and outdoor unit connecting pipe assembly, comprising a flow guide housing 1 for accommodating copper pipes and drain pipes and a connector 2. The flow guide housing 1 is composed of a cover plate 3 and an arc-shaped shell 4. The arc-shaped shell 4 is C-shaped, with snap-fit ​​seats 5 installed on both ends of the opening. A snap-fit ​​connector 6 is provided on the bottom of the cover plate 3, so that the cover plate 3 and the arc-shaped shell 4 are snapped together vertically and slidably connected laterally. The connection between the flow guide housing 1 and the flow guide housing 1 or the corrugated pipe is fixedly connected by the connector 2. The connector 2 includes an annular clamp 7 that fits against the outer wall of the arc-shaped shell 4 and a connecting screw 8. The two ends of the annular clamp 7 are fastened to the snap-fit ​​seat 5 by the connecting screw 8. A spiral groove hole 9 is also provided on the inner wall of the annular clamp 7. The cross-section of the spiral groove hole 9 is trapezoidal, which snaps against the outer wall of the corrugated pipe, so that the corrugated pipe is limited within the annular clamp 7. The cover plate 3 is a flat plate or an arc plate. In use, the copper pipe and the drain pipe are covered by the flow guide housing 1. The connection of the flow guide housing 1 is fixed and sealed by the connector 2. Where bending is required, a corrugated pipe is connected to the flow guide housing 1. The corrugated pipe is fixed and limited inside the flow guide housing 1 by the connector 2, which can provide protection at the bending point and reduce the aging of the drain pipe.

[0019] The card holder 5 has a sliding groove 10 inside, and the card connector 6 is a cylindrical part that is slidably connected to the sliding groove 10 in the transverse direction.

[0020] In this embodiment, a sliding groove 10 with both ends penetrating is opened in the snap-fit ​​seat 5, so that the snap-fit ​​connector 6 can be inserted into the sliding groove 10 from directly above the snap-fit ​​seat 5, and can slide left and right. When in use, contact the connection between the snap-fit ​​connector 6 and the sliding groove 10, remove the cover plate 3, leaving only the guide shell 1. After fixing the pipeline route of the copper pipe and the drain pipe installed in the guide shell 1, insert the entire covered pipe into the opening of the guide shell 1. After completion, the cover plate 3 can be directly fastened from the top of the opening to close it. When the guide shell 1 passes through the wall hole, the cover plate 3 can be slid and fastened from left to right to close the guide shell 1. The structure is simple and easy to use.

[0021] The end of the snap connector 6 is also provided with a ball head, the diameter of which is larger than the diameter of the snap connector 6, and the bottom of the corresponding sliding groove 10 is also provided with a circular groove hole to accommodate the ball head.

[0022] In this embodiment, the ball head is slightly larger than the cylindrical part, so that after the cover plate 3 is fastened to the flow guide housing 1, it will be locked by the ball head and cannot be directly pulled out along the opening direction. When fastened, the ball head can directly squeeze the sliding groove 10 from the opening to deform it and be interference-fitted into the flow guide housing 1 until the ball head falls into the circular groove hole, so that the sliding groove 10 is reset. This structure can be fastened during installation, but after installation, there is no force point and it cannot be removed in reverse. It can only slide laterally to open the cover plate 3 and the flow guide housing 1, which improves the sealing performance of the flow guide housing 1 and the cover plate 3, slows down the aging and corrosion rate of the internal drainage pipe, and improves the service life.

[0023] The inner wall of the arc-shaped shell 4 has an extension 11 and a recess 12 at equal distances on the left and right ends respectively. When two adjacent arc-shaped shells 4 are connected, the extension 11 of the former is inserted into the recess 12 of the latter.

[0024] In this embodiment, when the extension 11 and the recess 12 are inserted, the former presses on the latter. That is, according to the drainage direction of the drain pipe, the extension 11 is on the left and the recess 12 is on the right. When draining from left to right, the water flow always flows along the inside of the guide shell 1 and cannot leak outward. After the extension 11 and the recess 12 are connected, tape needs to be wrapped around the connection point for sealing. The accumulated tape will be accommodated by the spiral groove 9. There are no adhesive marks when viewed from the outside, which is beautiful and practical.

[0025] This utility model conceals the air conditioner's drain pipe and connecting copper pipe through a guide housing and connector, avoiding direct sunlight and high-temperature corrosion from rainwater, thus slowing down the aging process of the drain pipe. The connector allows for the connection of a corrugated pipe behind the guide housing, facilitating pipe routing at bends. The trapezoidal slot inside the connector spirally connects to the corrugated pipe, limiting its axial position. Simultaneously, the trapezoidal slot can accommodate adhesive tape to seal the gaps in the guide housing, improving sealing. The guide housing is inserted in the drainage direction, forming a unified whole through the connector. Even if the drain pipe ages, it can still drain outwards from the inside of the guide housing, serving as a temporary drainage pipe. This provides convenience for drain pipe replacement and is simple in structure and easy to use.

[0026] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
