[0037] In the embodiments of the present application, the second pipe network piece 4 can be slidably connected with the intermediate connecting piece 2 through one side structure of the outer frame; specifically, a through sliding groove matched with the side structure can be formed on the intermediate connecting piece 2, and then the side structure is matched as a sliding block in the through sliding groove to realize the sliding of the second pipe network piece 4 relative to the intermediate connecting piece 2.

[0038] In the embodiments of the present application, since the position adjusting assembly is controlled by the controller to act, and the position adjusting assembly is connected with the second pipe network piece 4, the position adjusting assembly not only serves as the driving piece 13 of the second pipe network piece 4, but also serves as the limiting piece of the second pipe network piece 4. Therefore, the additional limiting structure between the second pipe network piece 4 and the intermediate connecting piece 2 is not necessary to prevent the second pipe network piece 4 from retreating.

[0039] The air conditioner outdoor unit waste heat utilization device provided by the embodiments of the present application can realize the following effects: when the air conditioner load is small, the hot air exhaust amount of the air conditioner outdoor unit is small, at this time, the controller can control the position adjusting assembly to drive the second pipe network piece 4 to slide relative to the intermediate connecting piece 2 to make the network surfaces of the first pipe network piece 3 and the second pipe network piece 4 staggered with each other, the hot air passing area of the first pipe network piece 3 and the second pipe network piece 4 reaches the minimum, and the ventilation pipes in the first pipe network piece 3 and the second pipe network piece 4 can fully contact with the hot air to realize the full absorption of heat; when the air conditioner load is large, the hot air exhaust amount of the air conditioner outdoor unit is large, at this time, the controller can control the position adjusting assembly to drive the second pipe network piece 4 to slide relative to the intermediate connecting piece 2 to make the network surfaces of the first pipe network piece 3 and the second pipe network piece 4 completely coincide, the hot air passing area of the first pipe network piece 3 and the second pipe network piece 4 reaches the maximum, and the hot air backflow can be avoided.

[0040] In some possible embodiments, the position adjusting assembly is a reciprocating motion mechanism, and the moving end of the reciprocating motion mechanism is connected with the second pipe network piece 4.

[0043] It can be understood that the second pipe network piece 4 can also be connected with the cam 12 through a crank linkage.

[0044] In the embodiments of the present application, the use of the cam mechanism as the position adjusting assembly can avoid the setting of other sources such as a hydraulic source and an air pressure source, and the precision requirement of the cam mechanism is relatively low, and the overall cost is low.

[0045] In some possible embodiments, the first driven arm 8 and the intermediate connecting piece 2 can also be connected with the elastic piece 10.

[0046] In the embodiments of the present application, after the second pipe network piece 4 is vertically installed, if the second pipe network piece 4 moves upward under the driving of the cam mechanism, the setting of the elastic piece 10 can provide a buffering force for the second pipe network piece 4 in the uncontrolled state of the cam mechanism to avoid the collision between the first driven arm 8 and the intermediate connecting piece 2; if the second pipe network piece 4 moves downward under the driving of the cam mechanism, the setting of the elastic piece 10 can make the second pipe network piece 4 return to the original position after being adjusted. Preferably, the elastic piece 10 can be a spring.

[0047] In some possible embodiments, the cam mechanism in the cam mechanism is also provided with a driving wheel; the intermediate connecting piece 2 is slidably provided with a driving piece 13, and the driving piece 13 is in transmission cooperation with the driving wheel to drive the driving wheel to rotate when the driving piece 13 slides relative to the intermediate connecting piece 2.

[0049] In some possible embodiments, the driving member 13 is configured with an electric telescopic rod 15 to drive itself to slide relative to the intermediate connecting member 2, and the electric telescopic rod 15 is connected with the controller.

[0050] In some possible embodiments, a third pipe network member 5 is further included, the network surface of the third pipe network member 5 is arranged in parallel and spaced apart from the network surface of the first pipe network member 3, the third pipe network member 5 is slidably connected with the intermediate connecting member 2 in a manner that the network surface can be staggered with the network surface of the first pipe network member 3, the third pipe network member 5 and the second pipe network member 4 are respectively located on the two sides of the first pipe network member 3, and the third pipe network member 5 is further connected with the position adjusting assembly to slide relative to the intermediate connecting member 2 driven by the position adjusting assembly.

[0051] In the embodiment of the present application, the arrangement of the third pipe network member 5 can further improve the heat absorption amount, thereby improving the utilization efficiency of heat.

When the cam 12 is driven to rotate, the second pipe network member 4 and the third pipe network member 5 can slide in opposite directions.

[0052] In some possible embodiments, the intermediate connecting member 2 is two and respectively located on the opposite sides of the first pipe network member 3.

[0053] In the embodiment of the present application, when the intermediate connecting member 2 is provided as two, the sliding of the second pipe network member 4 and the third pipe network member 5 can be more smooth, and the second pipe network member 4 and the third pipe network member 5 can be prevented from being stuck during sliding.

[0054] In some possible embodiments, the two intermediate connecting members 2 are connected with the air conditioner outdoor unit through the hanger 1.

[0055] In the embodiment of the present application, the arrangement of the hanger 1 can facilitate the preheating utilization device to be more conveniently connected with the air conditioner outdoor unit, that is, the overall connection and disassembly of the preheating utilization device are realized, thereby facilitating maintenance.

[0056] In summary, the air conditioner outdoor unit preheating device provided by the application is installed on the air outlet of the central air conditioner outdoor unit through the hanger 1, and the heat absorption structure is installed through the intermediate connecting piece 2. The heat absorption structure is composed of the first pipe network piece 3, the second pipe network piece 4 and the third pipe network piece 5, which can absorb and utilize the heat of the air conditioner.

The air flow passing property is proportional to the overlapping degree, and the waste heat utilization rate is inversely proportional to the overlapping degree. Therefore, the overlapping degree of the first pipe network piece 3, the second pipe network piece 4 and the third pipe network piece 5 can be adjusted, which can balance the relationship between the air flow passing property and the waste heat utilization rate. Under the premise of ensuring the air flow passing property, the waste heat is utilized as much as possible to improve the effective utilization rate.
