[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 2 As shown, a waterproof connection device 100 for the outdoor unit 200 of a heat pump unit according to this utility model includes:

[0027] The base plate 110, the first side plate 120 and the second side plate 130 are fixedly disposed on the base plate 110; and the first rubber block 140 is fixedly disposed on the first side plate 120 and the second rubber block 150 is fixedly disposed on the second side plate 130.

[0028] Specifically, the base plate 110, the first side plate 120, and the second side plate 130 form a U-shaped plate with an opening at the top; in some embodiments, the first side plate 120 and the second side plate 130 are arranged in parallel opposite to each other, and further, the first side plate 120 and the second side plate 130 are arranged vertically on the base plate 110.

[0029] like Figure 3As shown, the outdoor unit 200 includes an outdoor unit top cover 210, an outdoor unit base plate 220, and four outdoor unit side plates 230. The outdoor unit side plates 230 include a first outdoor unit side plate 231, a second outdoor unit side plate 232, a third outdoor unit side plate (not shown), and a fourth outdoor unit side plate (not shown). The first outdoor unit side plate 231, the second outdoor unit side plate 232, the third outdoor unit side plate, and the fourth outdoor unit side plate are arranged in a circle around the outdoor unit base plate 220. The first outdoor unit side plate 231 is a detachable side plate for inspecting the interior of the outdoor unit 200. The second outdoor unit side plate 232 and the third outdoor unit side plate are arranged opposite each other and fixedly connected to the outdoor unit base plate 220. The fourth outdoor unit side plate can be either a fixed side plate or a detachable side plate.

[0030] Since the external unit 200 is not an improvement of the invention in this application, the internal structure of the external unit 200 is not further limited.

[0031] The top cover 210 of the outdoor unit has a downward-facing top cover flange 210A on one side, and the first outdoor unit side panel 231 has a downward-facing side panel flange 231A on one side.

[0032] The length of the first rubber block 140 is the same as the side length of the top cover 210 of the outdoor unit with the top cover flange 210A; the length of the second rubber block 150 is the same as the side length of the side plate 231 of the first outdoor unit with the side plate flange 231A.

[0033] To further prevent external water from entering the interior of the outdoor unit 200, the length of the base plate 110 is greater than the length of the second outdoor unit side plate 232 to the third outdoor unit side plate. Furthermore, a water guide block 180 is provided at one end of the base plate 110 to draw water out of the waterproof connection device 100 when water accumulates inside the waterproof connection device 100.

[0034] In order to fix the waterproof connection device 100 on the outdoor unit 200, the waterproof connection device 100 also includes a plurality of first connection positioning holes 160 fixedly disposed on the first side plate 120;

[0035] Specifically, a second connection positioning hole (not shown in the figure) corresponding to the first connection positioning hole 160 is provided on the second outdoor unit side plate 232 and the third outdoor unit side plate respectively. The waterproof connection device 100 can be fixedly installed on the two opposite outdoor unit side plates 230 by means of a screw connection structure, and the waterproof connection device 100 is located between the second outdoor unit side plate 232 and the third outdoor unit side plate.

[0036] To improve the connection strength between the waterproof connection device 100 and the top cover, the plate is thickened at the position of the first connection positioning hole 160.

[0037] To further improve positioning accuracy, a limiting block 170 is provided at one end of the waterproof connection device 100 to restrict the position of other components inside the outdoor unit 200. Specifically, the limiting block 170 can be set at one end of the first side plate or one end of the second side plate, and the specific setting position is determined according to the internal structure of the outdoor unit 200.

[0038] To drain any water that may enter the waterproof connection device 100 and prevent prolonged water retention that could lead to corrosion or leakage.

[0039] like Figure 4 As shown, during installation, the waterproof connection device 100 is first fixedly installed between the first side plate 120 and the second side plate 130 through the first connection positioning hole 160 and the second installation positioning hole. The first side plate 120 is located on the inside side close to the heat pump unit outdoor unit 200, and correspondingly, the second side plate is located on the inside side away from the heat pump unit outdoor unit 200.

[0040] At this time, the top cover flange 210A is precisely positioned inside the waterproof connection device 100, and the first rubber block 140 is in close contact with the outdoor unit top cover 210 to prevent moisture from entering the outdoor unit 200 through the gap between the outdoor unit top cover 210 and the first outdoor unit side panel 231; then the side panel flange 231A is positioned inside the waterproof connection device 100, and the second rubber block 150 is in close contact with the first outdoor unit side panel 231 to prevent moisture from entering the outdoor unit 200 through the gap between the outdoor unit top cover 210 and the first outdoor unit side panel 231, and to achieve the connection between the first outdoor unit side panel 231 and the outdoor unit 200.

[0041] Furthermore, to optimize the performance of the waterproof connection device 100, the waterproof connection device 100 also includes a first end plate and a second end plate (not shown in the figure). The first end plate and the second end plate are arranged perpendicularly to each other on the base plate 110, and the first end plate and the second end plate are disposed between the first side plate 120 and the second side plate 130 and fixedly connected thereto. Furthermore, a third rubber block and a fourth rubber block are fixedly disposed on the first end plate and the second end plate, respectively.

[0042] Specifically, the first end plate and the second end plate are respectively provided with grooves (not shown) for setting the top cover flange 210A and the side plate flange 231A.

[0043] In addition, the waterproof connection device 100 also includes a drainage unit (not shown) for draining water that may enter the waterproof connection device 100, preventing water from stagnating for a long time and causing corrosion or leakage. In some embodiments, a drainage hole is provided on the base plate 110 of the waterproof connection device 100, and a drainage pipe connected to the drainage hole is also included. The drainage pipe passes through the outdoor unit side plate 230 for draining water. Furthermore, the base plate 110 can also be configured to be inclined toward the drainage hole, which further facilitates the outflow of water.

[0044] Compared to existing technologies, this utility model provides a waterproof connection device for the outdoor unit of a heat pump unit. Through the cooperation of a U-shaped plate structure, rubber seals, and connection positioning holes, it achieves good waterproof effect and a stable connection, and is suitable for waterproof protection of equipment such as the outdoor unit of a heat pump unit. At the same time, the outdoor unit side panel used for inspecting the interior of the outdoor unit has a detachable connection structure with the outdoor unit, which facilitates the inspection and maintenance of the outdoor unit of the heat pump unit by technicians.
