Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioning pipeline connection structure, an air conditioning outdoor unit and an air conditioner. Background Art
[0002] In an air conditioner's outdoor unit, the valve body is typically secured to the valve plate with screws. For example, a three-way valve has one end connected to the compressor exhaust pipe, one end to the air conditioner's outdoor unit's heat exchanger, and the other end to the air conditioner's indoor unit's condenser or evaporator. The three-way valve itself is vibration-free. However, because it is connected to the compressor exhaust pipe, vibrations from the compressor and the refrigerant's pressure pulsation are transmitted to the valve during operation. Because the three-way valve is in rigid contact with the valve plate, the constant impact of the vibrating valve against the plate generates a loud noise. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.
[0029] The embodiments of the present application provide an air conditioning pipe connection structure, an air conditioning outdoor unit, and an air conditioner, which can effectively reduce noise. Detailed description is provided below with reference to the accompanying drawings.
[0030] See also Figure 1 , Figure 1 This is a schematic diagram of the first structure of the air-conditioning pipe connection structure provided in an embodiment of the present application.
[0031] The present embodiment provides an air conditioning pipe connection structure 100, which includes a valve body 10 and a damping mechanism 20. The valve body 10 includes a pipe 11 and a mounting base 12, which is fixed to the circumference of the pipe 11. The damping mechanism 20 includes a fixing assembly 21 and a damping pad 22. The fixing assembly 21 is connected to the damping pad 22, which is connected to the pipe 11 so that the damping pad 22 is fixed to the mounting base 12.
[0032] See also Figure 2 , Figure 2 A schematic structural diagram of the valve body provided in an embodiment of the present application.
[0033] The valve body 10 may be a three-way valve structure. This three-way valve structure has three ports: one port connected to the compressor exhaust pipe, one port connected to the heat exchanger of the air conditioner's outdoor unit, and another port connected to the condenser or evaporator of the air conditioner's indoor unit. The three-way valve itself does not vibrate. However, because it is connected to the compressor exhaust pipe, vibrations generated by the compressor and the pressure pulsation of the refrigerant are transmitted to the three-way valve during operation.
[0034] See also Figure 3 , Figure 3 for Figure 1 Explosion diagram. In order to fix the valve body 10, a mounting seat 12 is provided on at least one pipeline 11 of the three-way valve to fix the valve body 10 on the valve plate. A fixing hole 121 may be provided on the mounting seat 12, and the fixing hole 121 may be a threaded hole or a pin hole, and the valve body 10 may be subsequently fixed to the valve plate by bolts or pins. The mounting seat 12 can be fixed to the periphery of the pipeline 11 and extend along the radial direction of the pipeline 11. The number of the mounting seats 12 may be one or more to improve reliability. In an embodiment of the present application, the number of the mounting seats 12 may be two, which are symmetrically arranged. The vibration damping pad 22 is provided with an avoidance hole 222 corresponding to the fixing hole 121, which can also facilitate the insertion of bolts and pins.
[0035] Please continue reading Figure 1 The damping mechanism 20 includes a fixing assembly 21 and a damping pad 22. The fixing assembly 21 is connected to the valve body 10 and provides support for the damping pad 22, thereby securing the damping pad 22 to the mounting seat 12. The fixing assembly 21 maintains the relative position of the damping pad 22 and the mounting seat 12, preventing the damping pad 22 from falling off or shifting during the fixing process of the valve body 10, further improving stability. The damping pad 22 can be formed of a material with low rigidity but good elasticity, such as rubber.
[0036] Please continue to see Figure 3 The fixing assembly 21 includes a first fixing member 212 and a second fixing member 213. The first fixing member 212 is fixed on the pipeline 11. The second fixing member 213 is connected to the first fixing member 212. The second fixing member 213 is fixed on the mounting seat 12. The second fixing member 213 is connected to the vibration damping pad 22.
[0037] The first fixing member 212 and the second fixing member 213 can be made of plastic or metal.
[0038] See also Figure 4 The plane where the first fixing member 212 lies and the plane where the second fixing member 213 lies can form a certain angle, for example, a 90-degree angle, so that the vibration damping pad 22 fits more closely to the mounting base 12. The first fixing member 212 is fixed to the pipeline 11, which can limit the movement of the vibration damping pad 22 in the radial direction of the pipeline 11. The second fixing member 213 is fixed to the mounting base 12, which can limit the movement of the vibration damping pad 22 in the longitudinal direction of the pipeline 11. The constraints of the first fixing member 212 and the second fixing member 213 can effectively fix the relative position of the vibration damping pad 22 and the mounting base 12.
[0039] The first fixing member 212 is annular and is sleeved on the pipe 11. In other words, the first fixing member 212 is provided with a first through hole 2123, and the pipe 11 is passed through the first through hole 2123. Figure 2 The pipeline 11 is provided with a first groove 111, and the first fixing member 212 is engaged with the first groove 111. The first groove 111 can fix the first fixing member 212 to prevent the first fixing member 212 from sliding on the pipeline 11 along the length direction of the pipeline 11.
[0040] The second fixing member 213 is annular and is sleeved onto the mounting base 12, surrounding the mounting base 12. Specifically, the second fixing member 213 is provided with a second through-hole 2133, through which the mounting base 12 passes. Furthermore, the vibration-damping pad 22 is connected to the second fixing member 213, thereby preventing the second fixing member 213 from moving radially along the mounting base 12 and providing more options for fixing the vibration-damping pad 22.
[0041] See also Figure 4 , Figure 4 Schematic diagram of the structure of a fixing assembly provided in an embodiment of the present application. The first fixing member 212 is detachably connected to the second fixing member 213. The first fixing member 212 is provided with a slot 2121, and the second fixing member 213 is provided with a buckle 2131. The slot 2121 and the buckle 2131 are connected to fix the relative position of the first fixing member 212 and the second fixing member 213. In another embodiment, the first fixing member 212 is provided with a buckle 2131, and the second fixing member 213 is provided with a slot 2121. The slot 2121 and the buckle 2131 are connected to fix the relative position of the first fixing member 212 and the second fixing member 213.
[0042] The first fixing member 212 and the second fixing member 213 are connected by the slot 2121 and the buckle 2131, which is easy to disassemble and can be used as needed by the user. The second fixing member 213 and the vibration-damping pad 22 can also be replaced in time as consumables.
[0043] In the above situation, the first fixing member 212 is the first fixing member, the second fixing member 213 is the second fixing member, the first fixing member is sleeved on the pipeline 11, and the second fixing member is sleeved on the mounting seat 12, and is fixed by the buckle 2131 and the slot 2121 to fix the relative positions of the first fixing member, the second fixing member and the valve body 10.
[0044] Please continue reading Figure 4The first fixing member 212 is provided with an ear portion 2122, which is provided with a slot 2121. To simplify manufacturing and avoid reducing the strength of the first fixing member 212, the ear portion 2122 is provided on the first fixing member 212, and the ear portion 2122 is provided with a slot 2121. The position of the ear portion 2122 corresponds to the mounting base 12, so that the buckle 2131 of the second fixing member 213 fixed to the mounting base 12 can easily connect with the slot 2121 on the ear portion 2122.
[0045] See also Figure 1 、 Figure 4 as well as Figure 5 , Figure 5 This is a schematic diagram of the first structural embodiment of the vibration damping pad provided in the present application. The second fixing member 213 is provided with a locating pin 2132, which extends along the plane of the mounting base 12. The vibration damping pad 22 is provided with a locating hole 221, into which the locating pin 2132 engages to secure the vibration damping pad 22 to the second fixing member 213. The locating pin 2132 serves to position and secure the vibration damping pad 22. Furthermore, the plug-in connection between the second fixing member 213 and the vibration damping pad 22 facilitates timely replacement of the vibration damping pad 22, adapting to various situations.

Figure 7 This is a schematic diagram of the second structure of the vibration damping pad provided in an embodiment of the present application.
[0047] In some embodiments, the fixing assembly 21 is a third fixing member 214, which is connected to the vibration-damping pad 22. The third fixing member 214 and the vibration-damping pad 22 enclose an installation space 23, and the mounting base 12 is disposed in the installation space 23, so that the vibration-damping pad 22 is fixed to the mounting base 12. The third fixing member 214 can be a fixing belt.
[0048] Among them, see Figure 8 , Figure 8 for Figure 6 Schematic diagram of the explosion. The mounting base 12 is provided with a second groove 122, and the third fixing member 214 is engaged with the second groove 122. The second groove 122 can fix the third fixing member 214 to prevent the third fixing member 214 from sliding on the mounting base 12 along the length direction of the mounting base 12, which would cause the shock absorbing mechanism 20 to fall off.
[0049] The present application also provides an air conditioner outdoor unit, comprising a valve plate and the air conditioning pipe connection structure 100 of the above embodiment. The mounting base 12 is connected to the valve plate to secure the valve body 10 thereto, for example, using bolts or screws.
