It is needless to say that the person skilled in the art realizes that the described embodiments may be modified in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive in scope.

As shown in fig. 1, the fresh air system air inlet pipe condensation preventing device is arranged at a condensation section 31 between the fresh air fan 1 and the wall body 2 on the air inlet pipe 3, wherein the condensation section 31 is a section which is easy to generate condensation due to the temperature difference between the inside and the outside of the pipe. The device comprises two adapters 4 sleeved on a condensation section 31, an external condensation pipe 5 sleeved on the condensation section 31 is arranged between the two adapters 4, ventilation channels 41 communicated with the inner cavity of the condensation pipe 5 are respectively arranged on the adapters 4, one ventilation channel 41 on the adapter 4 is connected with an air outlet 11 of a fresh air fan 1, and the other ventilation channel 41 on the adapter 4 is connected with an air outlet pipe 6 through a pipeline.

In this embodiment, the condensation removing pipe 5 is sleeved outside the condensation removing section 31 to separate the condensation removing section 31 from the indoor environment, and exhaust air with a temperature relatively close to the indoor temperature is introduced into the condensation removing pipe 5 through the adapter 4. The exhaust air with higher temperature can continuously take away the water vapor generated by the outer wall of the tube of the condensation section 31 by utilizing the fluidity of the exhaust air, so that obvious condensation is not easy to occur at the condensation section 31, and the condensation problem is effectively avoided.

Preferably, the adaptor 4 near the wall 2 is disposed close to the wall 2, so that the condensation removing pipe 5 can remove water vapor from the end of the condensation segment 31 near the wall 2, that is, the head end of the condensation segment 31 in the air inlet direction. Preferably, the adaptor 4 near the fresh air machine 1 is disposed against the fresh air machine 1, so that the dew-eliminating pipe 5 can be close to eliminating the water vapor of the whole section of the dew-forming section 31. Based on the higher temperature of the exhaust air in the condensation eliminating pipe 5, the condensation eliminating pipe can heat the cold air in the condensation segment 31 to a certain extent, so that the inlet air reaching the end of the condensation segment 31, i.e. the inlet air about to enter the fresh air machine 1, can be lifted to a certain temperature. Therefore, the above arrangement of the adaptor 4 close to the fresh air machine 1 against the fresh air machine 1 is merely an optimal implementation manner of this embodiment, and when the adaptor 4 has a small distance from the fresh air machine 1, the dew condensation problem will not be obvious due to the increase of the air inlet temperature in the part of the dew condensation section 31 with the small distance, so that the dew condensation problem can be solved even if a certain interval is provided between the adaptor 4 and the fresh air machine 1, and the arrangement manner should be within the protection scope of the present utility model.

The adapter 4 is also arranged to be of a tubular structure, so that exhaust air capable of taking away water vapor exists at the adapter 4, the dead angle can be eliminated, and the anti-condensation effect is improved.

In this embodiment, the ventilation channel 41 on the adaptor 4 close to the fresh air fan 1 is connected to the air outlet 11 of the fresh air fan 1, and then the ventilation channel 41 on the adaptor 4 close to the wall 2 is connected to the air outlet pipe 6; of course, in actual use, the opposite connection mode, that is, the ventilation channel 41 on the adapter 4 close to the fresh air fan 1 is connected with the exhaust pipe 6, and the ventilation channel 41 on the adapter 4 close to the wall 2 is connected with the exhaust outlet 11 of the fresh air fan 1, which can achieve the same technical effect and belongs to the transformation of the same technical means.

Conventionally, the exhaust pipe 6 is installed on the wall 2 in a penetrating manner, and an exhaust connection pipe 61 is provided between the inner port of the exhaust pipe 6 and the corresponding ventilation channel 41 on the adapter 4 in this embodiment.

Preferably, an insulation layer is arranged outside the dew-eliminating pipe 5, so that the temperature difference between the inside and the outside of the dew-eliminating pipe 5 is not great originally, after the dew-eliminating pipe 5 is insulated by the insulation layer, dew is not easy to be formed outside the dew-eliminating pipe 5, and a good dew-preventing effect is also provided at the position of the dew-eliminating pipe 5. Similarly, an insulation layer is also provided outside the exhaust connection pipe 61.

According to the embodiment, the condensation pipe 5 and the adapter 4 are completely coated outside the condensation section 31, and exhaust air with relatively high temperature is introduced between the condensation pipe 5 and the adapter 4, so that water vapor condensed outside the pipe wall of the condensation section 31 can be taken away in real time, and the condensation problem is obviously solved. In addition, in the embodiment, only the adapter 4 and the dew eliminating pipe 5 are sleeved outside the dew condensation section 31, and then the exhaust pipe 6 is connected, so that the structure is simple, the cost is low, and the improvement and the application of the traditional structure are facilitated.
