In the scheme, the middle pipeline 300 is connected with the indoor unit 100 and the outdoor unit 200 in a direct butt welding mode, and the welding positions are arranged inside the indoor unit 100 and the outdoor unit 200, so that a stop valve which extends from the outside cannot exist in the state that the indoor unit 100 and the outdoor unit 200 exist independently, meanwhile, the stop valve protection is avoided by adopting a stop valve protection packaging material in the transportation process, and the installation space of a heat pump unit is increased.

The access panel assembly 500 is respectively disposed at bottom corner positions of the indoor unit 100 and the outdoor unit 200, and the access panel assembly 500 disposed on the indoor unit 100 corresponds to the access panel assembly 500 disposed on the outdoor unit 200.

Specifically, in this embodiment, the access panel assembly 500 includes an access main panel 510 and an access side panel 520 corresponding to the access main panel 510, the access main panel 510 is perpendicular to the axis of the middle pipeline 300, and the access side panel 520 is perpendicular to the access main panel 510.

The installation position of the access panel assembly 500 can be any position of the indoor unit 100 or the outdoor unit 200, and in this embodiment, the access panel assembly 500 is installed at a corner position and is provided with the access main panel 510 and the access side panel 520 which are perpendicular to each other, so that the size of the openings on the casings of the indoor unit 100 and the outdoor unit 200 can be increased, and a welding space for welding the intermediate pipe 300 can be provided. The maintenance main board 510 and the maintenance side board 520 are perpendicular to each other, so that the structural stability can be improved, and the phenomenon that the rigidity of the maintenance board assembly 500 is easy to deform due to the fact that the maintenance board assembly 500 is arranged on one side independently is avoided.

The service main plate 510 is provided with a line passing hole 600 through which the intermediate pipeline 300 can pass. In the process of welding the intermediate pipeline 300 with the indoor unit 100 and the outdoor unit 200, the intermediate pipeline 300 firstly passes through the wire through hole 600 on the service main board 510, then the intermediate pipeline 300 is directly butt-welded with the indoor unit 100 or the outdoor unit 200 in a state that the service panel assembly 500 is not assembled with the indoor unit 100 or the outdoor unit 200, and after the direct butt-welding is completed, the service panel assembly 500 is assembled with the corresponding indoor unit 100 or the corresponding outdoor unit 200 to seal the shell of the indoor unit 100 or the outdoor unit 200.

Since the intermediate pipe 300 needs to be moved relative to the wire through hole 600 during the assembly process, the outer diameter of the intermediate pipe 300 in this embodiment is smaller than the wire through hole 600.

Because the middle pipeline 300 can move relative to the access panel assembly 500 in the process of moving relative to the wire through hole 600, in order to avoid the damage of the middle pipeline 300 caused by the rupture of the access panel assembly 500 in the relative movement process, the rubber wire through protective sleeve is arranged in the wire through hole 600 in the scheme.

By providing the rubber protection sleeve 530, the intermediate pipeline 300 is in contact with the rubber protection sleeve 530 in the process that the intermediate pipeline 300 moves relative to the access panel assembly 500, thereby effectively preventing the intermediate pipeline 300 from being cut.

Since the middle duct 300 needs to move relative to the rubber protecting sleeve 530, in order to avoid excessive friction force of the relative movement, the size of the wire passing hole 600 in the rubber protecting sleeve 530 needs to be designed to be larger than the outer diameter size of the middle duct 300, and in this case, the rubber protecting sleeve 530 is difficult to effectively support and fix the middle duct 300, and the internal structure of the indoor unit 100 or the outdoor unit 200 can be seen through the gap between the wire passing hole 600 and the middle duct 300, so that the product is not beautiful and the safety cannot be guaranteed, therefore, a plurality of elastic supporting pieces 533 are extended inwards in the rubber wire passing protecting sleeve in the scheme. The elastic support piece 533 plays a role of supporting the middle pipeline 300 on one hand, and on the other hand, can cover gaps between the line holes 600 and the middle pipeline 300, so that the product structure is more attractive, and the safety is higher.

In addition to the above-mentioned support of the elastic support piece 533 for the middle pipeline 300, a pipeline support piece for supporting the middle pipeline 300 may be disposed on the sidewall of the access panel assembly 500, and the pipeline support piece bears the gravity of the middle pipeline 300, so as to prevent the welding interface from being easily broken due to the excessive stress applied to the welding interface between the middle pipeline 300 and the indoor unit 100 or the outdoor unit 200.
