Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning condensers, in particular to an antifreeze vertical coil structure of a central air-conditioning condenser. Background Art

[0002] The vertical coil in the central air conditioning condenser is an important component of the air conditioning system. It is mainly responsible for transferring the heat in the refrigerant to the outside air, thereby achieving a cooling effect.

[0003] After the central air conditioning condenser is completed, when in a low temperature environment, in order to reduce the risk of frostbite on the vertical coil, the medium in the vertical coil needs to be discharged. In the prior art (authorization announcement number CN213687020U3, a freeze-proof vertical coil structure for central air conditioning), a sealing knob is installed on the vertical coil to discharge the medium. However, the vertical coil design of the central air conditioning condenser usually has a complex structure, including multiple bending and folding parts. These structures make it easy for the medium to be retained in bends, dead corners and low-speed areas when flowing in the coil. At the same time, if the medium has a certain viscosity, the resistance of the medium will be greater when flowing in the coil, and it is easy to form retention and deposition, so that some impurities will remain on the inner wall of the vertical coil, thereby increasing the risk of frostbite on the vertical coil.

[0004] Therefore, there is an urgent need for a central air-conditioning condenser antifreeze vertical coil structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an antifreeze vertical coil structure for a central air-conditioning condenser, so as to solve the problem of residual impurities on the inner wall of the vertical coil proposed in the above background technology.

[0008] The connecting assembly includes a threaded tube arranged at one end of the mounting tube away from the hot air blower, a threaded sleeve is threadedly connected to the side wall of the threaded tube, and one end of the threaded sleeve is rotatably connected to the fixed tube.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figures 1-4 The illustrated central air-conditioning condenser antifreeze vertical coil structure includes a vertical coil body 102 disposed in a housing 101, a plurality of condensing fins 103 provided on the sidewall of the vertical coil body 102, and a discharge assembly disposed in the housing 101 for discharging the medium in the vertical coil body 102;

[0023] The exhaust assembly includes a hot air blower 201 disposed on one side of the housing 101. A mounting pipe 202 is provided at the output end of the hot air blower 201. A fixed pipe 203 is fixedly connected to the side wall of the vertical coil body 102 near the liquid inlet end. The fixed pipe 203 is connected to the mounting pipe 202 via a connecting assembly. The fixed pipe 203 is provided with a control assembly for controlling its passage.

[0024] It should be noted here that: through the setting of the discharge component, the impact force of the high-speed airflow is utilized to produce a strong impact on the medium that is trapped in the bend, dead corner or low speed, thereby destroying the adhesion and static state between the medium, making it loose and flowing with the airflow, and under the blowing action of the hot air, the medium is heated, thereby reducing the viscosity between the medium and the inner wall of the vertical coil body 102. At the same time, the hot air can heat the inner wall of the vertical coil body 102, so that the medium remaining on the inner wall can be evaporated, thereby improving the completeness of the discharge of the medium in the vertical coil body 102, reducing the residual medium on the inner wall of the vertical coil body 102, and thereby reducing the risk of frostbite of the vertical coil body 102.

[0025] It is worth noting that the central air conditioning condenser is an existing technology, and its specific structure and working principle have been mastered by people in this field, so they will not be elaborated here.

[0026] See also Figure 2 and Figure 3 The connecting assembly shown in the figure includes a threaded tube 301 provided at one end of the mounting tube 202 away from the hot air blower 201, a threaded sleeve 302 is threadedly connected to the side wall of the threaded tube 301, and one end of the threaded sleeve 302 is rotatably connected to the fixed tube 203;

[0027] It should be noted here that: through the setting of the connecting component, the connection and disassembly between the hot air blower 201 and the vertical coil body 102 are facilitated, so that when the vertical coil body 102 needs to discharge the medium, the hot air blower 201 is connected to the vertical coil body 102, and when the vertical coil body 102 does not need to discharge the medium, the hot air blower 201 is disassembled and removed, so as to reduce the space occupied by the shell 101 and the damage to the hot air blower 201 when it is idle for a long time.

[0028] See also Figure 2 and Figure 3 The control assembly shown in the figure includes a first circular plate 401 fixedly connected to the inner wall of the fixed tube 203. The first circular plate 401 is provided with a plurality of control holes 402. A second circular plate 403 is slidably connected to the side of the first circular plate 401 away from the threaded sleeve 302. The diameter of the second circular plate 403 is smaller than that of the first circular plate 401. A plurality of control rods 404 are fixedly connected to the side of the second circular plate 403 close to the first circular plate 401. The threaded tube 301 is provided with a drive assembly for driving each control rod 404.

[0029] It should be noted here that: by setting the control component, the fixed pipe 203 passage is automatically opened and closed, thereby ensuring the medium circulation flow needs when the vertical coil body 102 is normally used, while facilitating the hot air blowing operation when the medium is discharged.

[0030] See also Figure 4 , each control rod 404 shown in the figure is arranged in a conical shape, and the small end of the cone is arranged close to the first circular plate 401;

[0031] It should be noted that by configuring the control rod 404 to be tapered, the blocking effect of the control rod 404 on the control hole 402 is improved.

[0032] Working principle: After the central air conditioning condenser has completed its work, when in a low temperature environment, in order to reduce the risk of frostbite on the vertical coil body 102, it is necessary to discharge the medium in the vertical coil body 102. When discharging the medium from the vertical coil body 102, the medium's own flow effect is first utilized to make the medium flow out from the liquid outlet end of the vertical coil body 102, thereby discharging most of the medium from the vertical coil body 102;

[0033] After most of the medium in the vertical coil body 102 is discharged, the hot air blower 201 is placed on the shell 101, and then the installation pipe 202 at the output end of the hot air blower 201 is connected to the fixed pipe 203 using a connecting assembly. In the process of connecting the installation pipe 202 and the fixed pipe 203, the blockage of the fixed pipe 203 will be released, so that the passage of the fixed pipe 203 is opened. After the passage of the fixed pipe 203 is opened, the hot air blower 201 is started, so that a large amount of hot air flows from the fixed pipe 203 to the inside of the vertical coil body 102, so that under the action of a large amount of hot air, the impact force of the high-speed airflow is used to The hot air has a strong impact on the medium passing through the channel, dead corner or low speed, thereby destroying the adhesion and static state between the medium, making it loose and flowing with the air flow, and under the blowing action of the hot air, the medium is heated, thereby reducing the viscosity between the medium and the inner wall of the vertical coil body 102. At the same time, the hot air can heat the inner wall of the vertical coil body 102, so that the medium remaining on the inner wall can be evaporated, thereby improving the completeness of the discharge of the medium in the vertical coil body 102, reducing the residual medium on the inner wall of the vertical coil body 102, and further reducing the risk of frostbite of the vertical coil body 102.

[0034] Example 2

[0035] See also Figure 3 and Figure 4 This embodiment further explains Example 1. The driving assembly shown in the figure includes a first fixing plate 501 fixedly connected to the inner wall of the threaded tube 301. A driving rod 502 is fixedly connected to the side of the first fixing plate 501 close to the threaded sleeve 302. A second fixing plate 503 is fixedly connected to the inner wall of the fixed tube 203. The second fixing plate 503 is slidably connected to a T-shaped rod 504. One end of the T-shaped rod 504 is slidably connected to the first circular plate 401 and connected to the second circular plate 403. The T-shaped rod 504 is provided with a telescopic assembly for telescoping the second circular plate 403.

[0036] It should be noted here that: through the setting of the drive assembly, during the connection process of the threaded tube 301 and the threaded sleeve 302, the threaded tube 301 will continue to move closer to the fixed tube 203, thereby further driving the drive rod 502 on the first fixed plate 501 to continue to move closer to the T-bar 504. When the drive rod 502 and the end face of the T-bar 504 are against each other, under the driving force, the second circular plate 403 will be pushed away from the first circular plate 401, and then each control rod 404 will be moved out of the control hole 402, thereby releasing the blockage of the fixed tube 203 passage, allowing hot air to flow from the gap between the second circular plate 403 and the fixed tube 203 to the vertical coil body 102.

[0037] See also Figure 3 and Figure 4, the telescopic component in the figure is a telescopic spring 6, which is sleeved on the side wall of the T-shaped rod 504, and the two ends of the telescopic spring 6 are respectively connected to the second fixed plate 503 and the side wall of the T-shaped rod 504;

[0038] It should be noted here that: through the setting of the telescopic component, the elastic force of the telescopic spring 6 is used to drive the second circular plate 403 to move closer to the first circular plate 401 when the push on the T-bar 504 is released, so that the control rod 404 is inserted into the control hole 402, which is used to block the control hole 402, thereby achieving the blocking of the fixed pipe 203 pipeline.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
