Description

Technical Field

[0001] The utility model mainly relates to the technical field of air conditioning, in particular to a pipe fixing structure for an internal unit of a heat pump air conditioner. Background Art

[0002] In a heat pump air conditioner, the refrigerant exchanges heat between media in the plate heat exchanger through pipes. At the same time, the moisture in the air will liquefy around the plate heat exchanger when it is cooled to form condensed water. Therefore, it is necessary to install a water collection pan in the heat pump air conditioner to provide a water storage function to prevent the condensed water from flowing to the ground or corroding other parts of the heat pump air conditioner.

[0003] Since the water tray has no strong fixing points, the movement of the pipeline cannot be restrained. At the same time, the movement of the pipeline (water inlet pipe, water outlet pipe, refrigerant liquid pipe, refrigerant gas pipe) will also cause deviation, so the pipeline needs to be fixed. The current fixing structure generally uses a double U-shaped fixing block with screws and nuts for fixing. When the pipeline is subsequently maintained or replaced, other tools are needed to remove the screws and nuts, which is time-consuming and affects pipeline maintenance. Utility Model Content

[0036] In this embodiment, it should be noted that the rubber pad 17 can increase the friction resistance, and can more effectively fix the air conditioner indoor pipe, while preventing the U-shaped block from causing wear to the air conditioner indoor pipe.

[0037] The specific operation mode of the utility model is as follows:

[0038] First, according to the routing of the heat pump air conditioner indoor unit pipeline, a certain number of positioning components 10 are installed at the appropriate position of the assembly plate 20 through the threaded shaft 14 and the threaded hole 21, and then the heat pump air conditioner indoor unit pipeline is placed between the lower U-shaped block 11 and the upper U-shaped block 12, and then the U-shaped block is closed. At this time, the L-shaped connecting block 31 is rotated and inserted between the fixing blocks 32, and the buckle block 35 is popped out of the positioning slot 33 by the force of the spring 36, thereby completing the fixation between the U-shaped block and the pipeline, and then the positioning piece 15 is lowered by rotating the adjusting bolt 16, and the heat pump air conditioner indoor unit pipeline is accurately fixed in cooperation with the lower U-shaped block 11;

[0039] When it is necessary to maintain the pipeline, the buckle block 35 in the positioning slot 33 can be pressed to retract it, and then the lower U-shaped block 11 and the upper U-shaped block 12 can be opened.
