Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning volutes, in particular to the technical field of quick-disassembly volutes of air-conditioning duct units. Background Art

[0002] The air conditioning volute is a crucial component of an air conditioning system. It's the outer shell that surrounds the air conditioner's impeller or rotor, typically made of metal or synthetic materials. The volute's cross-section often features a rectangular design, making it simple to manufacture and weld. Its profile resembles a snail, and its flow path gradually expands around the impeller, collecting and directing air. This design gradually reduces the velocity of the airflow, converting some of the kinetic energy into static pressure, thereby more effectively controlling the flow of air. When the air conditioning system is operating, the high-speed rotation of the impeller generates noise. The air conditioner volute encases the impeller, reducing this noise and improving the comfort of the air conditioning system.

[0003] For example, Chinese utility model patent publication number CN200999765Y proposes a removable, integrated impeller volute structure for the indoor side of a room air conditioner. The volute structure primarily consists of an upper volute member and a lower volute member, which are connected and secured by a connector. The upper volute member is equipped with a small hook for securing signal cables and a post with a screw hole. The sides of the upper and lower volute members each feature a small, shearable tab. The lower volute member has a cylindrical hole with a retaining rib. The volute structure in this patent is mainly composed of two left and right volute upper parts and a volute lower part. During installation, both volutes need to be fixed on the corresponding fixed structure of the air conditioner, which makes disassembly inconvenient. The connection structure between the volute and the air conditioner needs to be removed. Moreover, if only one side of the volute structure of the volute is removed, the opening may not be large enough to remove the internal air-conditioning fan or impeller. Both sides of the volute need to be removed, and the motors installed on both sides of the volute may also need to be removed to facilitate the removal of the volute and the fan inside it, which is time-consuming and labor-intensive. Summary of the Invention

[0028] See Figure 1-Figure 5The utility model is a quick-detachable volute for an air-conditioning duct unit, comprising a volute body 1, wherein the volute body 1 is provided with a volute cavity 11 for installing equipment, the volute body 1 comprises a first half shell 12 and a second half shell 13, the volute cavity 11 is formed by the first half shell 12 and the second half shell 13, the first half shell 12 is provided with a first connecting surface 121 on both sides, the second half shell 13 is provided with a second connecting surface 131 for cooperating with the first connecting surface 121, the first connecting surface 121 and the second connecting surface 131 are all arranged axially along the volute body 1 or inclined relative to the axis of the volute body 1, and the first connecting surface 121 and the second connecting surface 131 are respectively provided with a limiting slide groove 122 and a limiting slide rail 132 that cooperate with each other. The limiting slide rail 132 is axially slidable and cannot be radially loosened in the limiting slide groove 122. A fixing portion 124 is provided on the first half shell 12, and an opening 1241 communicating with the volute cavity 11 is provided on the fixing portion 124, and the fixing portion 124 is used to fix the volute body 1. In this embodiment, the volute body 1 is set to a structure composed of a first half shell 12 and a second half shell 13, and the first half shell 12 and the second half shell 13 are detachably connected, which is convenient for opening the volute cavity 11 to maintain and manage the equipment in the volute cavity 11, and is easy to use. A limiting slide groove 122 and a limiting slide rail 132 are provided between the first half shell 12 and the second half shell 13 for connection. The limiting slide groove 122 and the limiting slide rail 132 cooperate to play a radial limiting role, and the connection is more stable. During installation and disassembly, the first half shell 12 and the second half shell 13 are relatively axially pulled out to separate the limiting slide groove 122 and the limiting slide rail 132, and the volute body 1 can be opened. The installation and disassembly are convenient. There is no need to disassemble the fixing part 124 during disassembly, and there is no need to disassemble the entire volute body 1, which is more convenient.

[0029] Preferably, the limiting slide groove 122 is a dovetail slide groove, and the limiting slide rail 132 is a dovetail slide rail.

[0030] See Figure 2 The lower side of the volute body 1 is provided with a drainage hole 15 connected to the volute cavity 11. It is convenient for drainage. When the inside of the air conditioner volute is simply cleaned, the internal sewage can be discharged through the drainage hole 15.

[0031] Preferably, the drainage hole 15 is provided with a sealing member detachably connected thereto, which is used to seal the drainage hole 15 under normal circumstances.

[0032] See Figure 4 、 Figure 5A first connecting screw hole 123 and a first connecting through-hole 133 are respectively provided in the middle of the first connecting surface 121 and the middle of the second connecting surface 131 to cooperate with each other. A bolt passes through the first connecting through-hole 133 and is fixedly connected to the first connecting screw hole 123. By bolting the first connecting through-hole 133 and the first connecting screw hole 123, the relative position of the first half shell 12 and the second half shell 13 can be locked. The first connecting through-hole 133 and the first connecting screw hole 123 are provided in the middle of the connecting surfaces. When fixed by bolts, they can ensure that the middle portions of the first connecting surface 121 and the second connecting surface 131 are tightly connected.

[0035] See Figure 4 The limiting slide groove 122 is provided with an open portion 1221 for the limiting slide rail 132 to pass radially. Installation is more convenient. When installing, the limiting slide rail 132 can first find the position of the open portion 1221, then enter the limiting slide groove 122 through the open portion 1221 and then move axially. It is more convenient to use and does not need to enter through the end of the limiting slide groove 122.

[0036] See Figure 4 、 Figure 5 The limiting rail 132 has two sections, one located at each end of the second connecting surface 131; the limiting slot 122 has two sections, one located at each end of the first connecting surface 121. The end of the limiting slot 122 near the limiting rib 14 extends through the first connecting surface 121, while the other end of the limiting slot 122 is closed at both ends, but has an open portion 1221. The segmented limiting rail 132 and limiting slot 122 reduce friction and ensure smoother pulling.

[0037] See Figure 1 、 Figure 5 The connection between the first half shell 12 and the second half shell 13 is provided with a shielding fold 16 for shielding the seam between the first half shell 12 and the second half shell 13. The shielding fold 16 can shield the seam position and improve the sealing performance.
