The air conditioning pipeline structure and the air conditioner of the present application will be described below with reference to FIGS. 1 to 4 .

Referring to FIG. 1 , this embodiment provides an air conditioning pipeline structure, which includes a drain pipe 1 and a refrigerant pipe 2 . The drain pipe 1 and the refrigerant pipe 2 are respectively used to pass through the air conditioner indoor unit, and the drain pipe 1 is wound around the outside of the refrigerant pipe 2 . The drain pipe 1 is used to discharge the condensed water of the indoor unit of the air conditioner; one end of the drain pipe 1 is connected to the indoor unit of the air conditioner, and the other end is used to pass out to the outdoors. The refrigerant pipe 2 is used to connect the air conditioner indoor unit and the air conditioner outdoor unit to form a refrigerant circuit. One end of the refrigerant pipe 2 is connected to the indoor unit of the air conditioner, and the other end is passed out of the indoor unit and out to the outside to be connected to the outdoor unit of the air conditioner. Both the drain pipe 1 and the refrigerant pipe 2 need to be routed out of the indoor unit and out to the outdoors. Because the temperature of the condensed water of the indoor unit is relatively low and has a certain cooling capacity, in the prior art, directly discharging the condensed water to the outdoors through the drain pipe 1 will cause the loss of cooling capacity of the condensed water.

In the air conditioning pipeline structure provided in this embodiment, it is proposed to wrap the drain pipe on the outside of the refrigerant pipe 2, and the cooling capacity of the condensed water in the drain pipe can effectively prevent the heat exchange between the refrigerant pipe 2 of the same low temperature and the outside air, and can Reducing the loss of cooling capacity in the second passage of the refrigerant pipe, thereby improving the cooling and heating effect of the air conditioner, and realizing the recycling and utilization of the cooling capacity of the condensed water, which is conducive to saving energy and avoiding energy waste; The refrigerant pipe 2 also needs to pass out of the indoor unit, so that the pipeline structure can be realized by using the existing air conditioner structure without adding components.

On the basis of the above embodiment, further referring to FIGS. 3 and 4 , the drain pipe 1 includes a drain pipe body 11 and a thermal insulation layer 12 . Disposing the thermal insulation layer 12 on the outside of the drain pipe body 11 not only helps to reduce the loss of the cooling capacity of the condensed water in the drain pipe Direct exposure can reduce the weathering of the inner pipe, which is beneficial to improve the service life of the drain pipe 1 and reduce the replacement frequency, thereby improving the user experience.

Further, referring to FIG. 4 , the drain pipe body 11 is divided into two parts in the circumferential direction, wherein the first part 111 is in contact with the refrigerant pipe 2 , and the surface of the second part 112 is provided with the insulation layer 12 . That is, the main body 11 of the drain pipe is not provided with the thermal insulation layer 12 all along the circumference. This embodiment specifically considers that if a ring of thermal insulation layer 12 is arranged around the drain pipe body 11, although it can play a role of heat preservation and protection, it will also affect the exchange of cold energy between the drain pipe 1 and the refrigerant pipe 22. As a result, the cold energy in the drain pipe 1 cannot be transferred to the refrigerant pipe 2, which will also cause waste of the cold energy of the condensed water.

Based on this, the present embodiment proposes to set the insulation layer 12 on a part of the periphery of the drain pipe body 11 , that is, only set a half-circle of the insulation layer 12 on the periphery of the drain pipe body 11 (here, the half circle is not limited to half a circle, It is only used to illustrate that the thermal insulation layer 12 is not provided in a whole circle, and the thermal insulation layer 12 is disconnected in the circumferential direction), so that part of the surface of the drain pipe body 11 is exposed without the thermal insulation layer 12 .

The arrangement of the corrugated structure 13 can also facilitate the firm connection with the thermal insulation layer 12, because the corrugated structure 13 makes the second part 112 of the drain pipe body 11 in a concave and convex shape, and the thermal insulation layer 12 can be embedded with the corrugated structure 13, thereby improving thermal insulation. The firmness and stability of the layer 12 reduces the probability of the insulation layer 12 falling off.

The semicircular drain pipe body 11 has a semicircular surface and a plane in the circumferential direction, and the plane is the first part 111 of the drain pipe body 11 . , the semicircular surface is the second part 112 of the main body 11 of the drain pipe; the plane part can be exposed for contact with the refrigerant pipe 2 during winding; the semicircular surface part can be provided with a corrugated structure 13 and an insulating layer 12 on the outside.

Further, in another embodiment, the drain pipe body 11 has an elliptical structure, and the oval drain pipe body 11 can be divided into two symmetrical parts with respect to the longer radial direction, one of which is the first part 111 of the drain pipe body 11 , used to contact the refrigerant pipe 2 during winding; the other part is the second part 112 of the drain pipe body 11 , which can be provided with a corrugated structure 13 and a thermal insulation layer 12 on the outside.

Here, the width of the drain pipe 1 can be the maximum outer diameter of the drain pipe. That is to say, this embodiment considers that if the drain pipe 1 is wound too densely on the outside of the refrigerant pipe 2, it may affect the flow of condensed water in the drain pipe 1 and affect the discharge of the condensed water. Therefore, this embodiment proposes to wrap the drain pipe. 1, a certain distance can be set between two adjacent circles of drain pipes 1, so that the drain pipes 1 are not wrapped too densely, which is beneficial to ensure the smooth discharge of condensed water.
