The utility model provides a new trend pipe 100, this new trend pipe 100 are used for the air conditioner, and the air conditioner includes new trend module, refrigerant pipe 210, drain pipe 220 and electric wire 230. In an embodiment of the present invention, please refer to fig. 1, one end of the fresh air duct 100 is used for communicating with the fresh air module, and the other end is used for penetrating through the wall 300 and extending out of the room; the wall of the fresh air duct 100 is provided with a through hole 103, and at least one of the refrigerant pipe 210, the water discharging pipe 220 and the electric wire 230 is inserted into the through hole 103 so as to penetrate through the wall 300 and extend out of the room.
The air conditioner is provided with an air conditioner indoor unit and an air conditioner outdoor unit, and the fresh air module is arranged in the air conditioner indoor unit and used for introducing outdoor air into a room so as to update the indoor air. Fresh air duct 100 is inside hollow pipeline structure, and the air can flow wherein, and the new trend module is connected with fresh air duct 100's one end, inhales outdoor air and carries to indoor through fresh air duct 100's tube inner space 104. That is, the fresh air duct 100 is an air duct for communicating the indoor space and the outdoor space, and thus the wall 300 through which the fresh air duct 100 passes is not only a cement wall in the conventional sense, but also should be understood to include a partition, a window, and the like for separating the indoor space and the outdoor space. The wall thickness of the fresh air pipe 100 is 2mm to 4mm, the cost is high due to the excessively thick pipe wall, and under the condition that the wall penetrating space is certain, the thicker the pipe wall, the smaller the inner diameter of the pipe body pipe, and the fresh air quantity is influenced; the pipe wall is too thin, the process is not easy to realize, the heat preservation effect of the pipe body is poor, and the condensation problem can occur on the hot air side due to the indoor and outdoor temperature difference. In addition, the size of the wall-through space of the wall 300 cannot be too large or too small, which would increase the wall-through cost and affect the structural strength of the wall 300, and too small would be unfavorable for the passing of each pipeline. Therefore, the wall thickness of the fresh air duct 100 in this embodiment is designed to be 2mm to 4mm, for example, 2mm, 2.5mm, 3mm or 4mm, so as to reduce the occupation of the wall penetrating space on the premise of ensuring the transportation of the outdoor air. Since the inner diameter of the fresh air duct 100 directly affects the resistance of the fresh air duct 100 to the air flow, the larger the inner diameter of the duct is, i.e., the larger the cross-sectional area of the air passing, the smaller the duct resistance is, and the larger the fresh air volume is, the more the fresh air volume is, and therefore, on the premise that the wall penetrating space of the wall 300 is not changed, the inner diameter of the duct of the fresh air duct 100 needs to be increased by fully utilizing the wall penetrating space, so as to increase the fresh air volume of the fresh air module.
In the air conditioner, the refrigerant pipe 210, the drain pipe 220, and the electric wire 230 need to penetrate the wall 300 in addition to the fresh air duct 100: the refrigerant pipe 210 is used to connect an air conditioner indoor unit and an air conditioner outdoor unit, and is used for circulation of a refrigerant, thereby realizing cooling or heating; the drain pipe 220 is connected with the air conditioner indoor unit, and the air conditioner indoor unit needs to drain water in the working process, for example, the air conditioner indoor unit can generate condensed water during refrigeration, and the condensed water needs to be drained in time, so the drain pipe 220 is arranged, the condensed water is drained through the drain pipe 220, for example, the air conditioner indoor unit is provided with a washing module for cleaning a filter screen, and dirty water also needs to be drained through the drain pipe 220; the electric wire 230 is used to connect the indoor unit and the outdoor unit of the air conditioner, and is used to transmit electric power and/or electric signals, etc. to ensure the normal operation of the air conditioner. Therefore, the refrigerant pipe 210, the water discharge pipe 220, and the electric wire 230 also need to penetrate the wall 300.
In the prior art, the pipelines penetrate through the wall 300 side by side, and a large number of gaps exist among the pipelines, so that the wall penetrating space of the wall 300 cannot be effectively utilized. For example, taking the fresh air duct 100 and the refrigerant duct 210 as an example, the fresh air duct 100 and the refrigerant duct 210 are closely arranged right and left to pass through the wall 300, and then a gap is generated between the fresh air duct 100 and the refrigerant duct 210 at the upper and lower sides, and the gap cannot be effectively utilized.
Therefore, in this embodiment, the through hole 103 is formed in the wall of the fresh air duct 100, and the through hole 103 may be formed at any position of the wall of the fresh air duct 100 located at the indoor portion, for example, may be formed on the wall near the casing of the indoor unit of the air conditioner, or may be formed on the wall near the wall 300, and for the fresh air duct 100 arranged in a bent shape, the through hole may also be formed on the wall at the bent portion 102; the shape of the through hole 103 may be triangular, circular, elliptical, hexagonal, square, or the like; the through hole 103 may be sized to receive at least one of the refrigerant pipe 210, the drain pipe 220, and the electric wire 230 therethrough. At least one of the refrigerant pipe 210, the water discharge pipe 220 and the electric wire 230 extends into the pipe space 104 of the fresh air pipe 100 through the through hole 103, penetrates through the wall 300 through the pipe space 104, and extends to the outside, that is, the gaps between the pipelines when the pipelines penetrate the wall side by side are transferred to the pipe space of the fresh air pipe 100, so that the pipe inner diameter of the fresh air pipe 100 is increased by reasonably utilizing the wall penetrating space, and the fresh air volume of the fresh air module is increased.
For example, taking the fresh air duct 100 and the refrigerant duct 210 as an example, the through hole 103 is formed in a duct wall near a casing of an indoor unit of an air conditioner, and is hexagonal in shape, and the equivalent diameter is 30mm, the refrigerant duct 210 enters the duct internal space 104 of the fresh air duct 100 through the through hole 103, penetrates through the wall 300 through the duct internal space 104, and extends out of the room, compared with the case where there is no through hole 103 (the fresh air duct 100 and the refrigerant duct 210 are closely adjacent to and pass through the wall 300 side by side), a gap between the ducts of the fresh air duct 100 and the refrigerant duct 210 is eliminated, even if the drain pipe 220 and the electric wire 230 do not enter the duct internal space 104 through the through hole 103 (and pass through the wall 300 side by side with the fresh air duct 100), compared with the scheme without the through hole 103, the duct internal diameter of the fresh air duct 100 can be increased more reasonably by using the wall-penetrating space, so as to increase the fresh air volume of the fresh air module.
For another example, referring to fig. 1 to 6, the fresh air duct 100 is bent, the through hole 103 is formed on the wall of the bent portion 102 of the duct body, the shape is circular, the diameter is 60mm, the refrigerant duct 210, the water discharge duct 220 and the electric wire 230 all enter the duct space 104 of the fresh air duct 100 through the through hole 103, and penetrate the wall 300 through the duct space 104 to extend to the outside, so that when the fresh air duct 100 penetrates the wall 300, no space is required for the ducts, the wall can be tightly attached to the wall penetrating hole, the wall penetrating space is utilized to the maximum extent, the inner diameter of the duct is maximized, and the fresh air volume of the fresh air module is increased to the maximum extent.
For another example, referring to fig. 1, the refrigerant pipe 210, the water discharge pipe 220 and the electric wire 230 are bound into a whole, enter the pipe space 104 of the fresh air pipe 100 through the through hole 103, penetrate the wall 300 through the pipe space 104, and extend to the outside.
The following table and fig. 7 reflect the influence of an embodiment of the present invention on the fresh air volume compared with the prior art.
| Rotating speed (r/min) | Fresh air volume before improvement (m 3/h) | Improved fresh air volume (m 3/h) |
| 2000 | 21.8 | 50 |
| 2250 | 25.0 | 53 |
| 2500 | 27.9 | 56 |
| 2750 | 31.0 | 60.5 |
| 3000 | 34.0 | 63.3 |
Compared with the prior art, the fresh air quantity of the fresh air module is remarkably increased.
In an embodiment of the present invention, please refer to fig. 1 to 6, the fresh air duct 100 is bent, and the through hole 103 is disposed on the outer wall of the bending portion 102 of the duct body (the fresh air duct 100 is horizontally disposed, and the fresh air duct 100 is divided into two parts along the tubular shaft in the direction perpendicular to the horizontal plane, the part of the duct wall length smaller than the tubular shaft is the inner wall, and the part of the duct wall length larger than the tubular shaft is the outer wall). When the refrigerant pipe 210, the water discharge pipe 220 and the electric wire 230 penetrate through the wall 300, a portion of the pipeline located in the wall 300 is not parallel to the wall 300, for example, at an angle of 60 degrees, 90 degrees or 120 degrees, and for convenience of description and understanding, the following description will use a vertical direction as an example. When the pipes are led out from the indoor unit of the air conditioner, if the pipes are parallel to the wall 300 to be penetrated, the pipes need to be bent near the wall penetrating hole to penetrate through the wall 300. In this embodiment, the bent portion of the fresh air duct 100 divides the fresh air duct into an indoor section 101a and a wall-passing section 101b, and the wall-passing section 101b is perpendicular to the wall 300. The through holes 103 are formed in the outer side pipe wall of the bending part 102, so that pipelines perpendicular to the wall 300 can directly enter the inner space 104 of the fresh air pipe 100 through the through holes 103 conveniently, and the pipelines are not required to be wound to other positions to be bent more, that is, the through holes 103 are formed in a necessary path for the refrigerant pipe 210, the drain pipe 220 and the electric wire 230 to reach the wall through hole, and the implementation difficulty is reduced.
In an embodiment of the present invention, referring to fig. 1, fig. 3, fig. 4 and fig. 5, the fresh air duct 100 further includes a sealing ring 110, the sealing ring 110 has elasticity, and an outer wall of the sealing ring abuts against a periphery of the through hole.

In this embodiment, the insect-proof net 120 is embedded in the fresh air duct 100 at an end of the duct for extending out of the room, so as to play a role of mouse and insect prevention. Since the water draining pipe 220 is not suitable for draining water in the pipe space 104 of the fresh air pipe 100 to prevent air in the pipe and water drained from the water draining pipe 220 from being sucked into the fresh air module when the fresh air module is in operation, and the condenser pipe and the electric wire 230 need to be connected to an outdoor unit of the air conditioner, at least one of the condenser pipe, the water draining pipe 220 and the electric wire 230 must pass through the insect-proof net 120 to extend out of the room after entering the pipe space 104 through the through hole 103. Therefore, in the present embodiment, the pipe opening 121 is disposed on the surface of the insect-proof net 120, and at least one of the refrigerant supply pipe 210, the water discharge pipe 220 and the electric wire 230 passes through the pipe inner space 104 of the fresh air pipe 100 to the outside. The size of the through pipe orifice 121 is just enough to accommodate each pipeline in the fresh air pipe 100 to pass through, so that the insect prevention effect is greatly influenced, and the too small pipeline cannot pass through smoothly; the shape can be determined according to the arrangement form of each pipeline to be penetrated, and can be triangular, hexagonal, square, oval or round; the through-opening 121 may be opened at the center of the anti-insect net 120, or may not be opened at the center, for example, at a position near the center of the anti-insect net 120, at a position near the edge of the anti-insect net 120, or at the edge of the anti-insect net 120. Thus, at least one of the refrigerant pipe 210, the water discharge pipe 220 and the electric wire 230 can pass through the nozzle 121 and pass through the inner space 104 of the fresh air pipe 100 to the outside.
