Detailed Description

For a clearer understanding of technical features, objects and effects of the present utility model, a detailed description of embodiments of the present utility model will be made with reference to the accompanying drawings.

Referring to fig. 1 to 2, fig. 1 shows an overall structure of a heat pump main unit according to an embodiment of the present utility model, the heat pump main unit includes a waterproof structure including a cabinet 1, an outdoor side heat exchanger 10 disposed inside the cabinet 1, and an electric cabinet 20. Fig. 2 is a schematic structural diagram of fig. 1, from which part of the casing 1 is removed, in which the vertical direction of the sign corresponds to the height direction of the casing 1, and in which the electric cabinet 20 is shown below the outdoor side heat exchanger 10 along the height direction of the casing 1, that is, the electric cabinet 20 is closer to the ground than the outdoor side heat exchanger 10, so that it is convenient for personnel to overhaul the electric cabinet 20.

As shown in fig. 5, in some embodiments, the electric cabinet 20 includes a cabinet 24, a circuit board module 23, and a terminal module 25. The circuit board module 23 and the terminal module 25 are both disposed in the case 24. The terminal module 25 is disposed below the circuit board module 23 for connecting the external cable and the circuit board module 23, respectively, as a connection medium between the external cable and the circuit board module 23. The connection between the external cable and the circuit board module 23 can be achieved by the service personnel only by connecting the cable at the wiring terminal module 25. Therefore, the cable connection of the circuit board can be conveniently carried out by an maintainer.

As shown in fig. 3, in some embodiments, the casing 1 is provided with a first ventilation part 21 communicating with the outside air, and the case 24 is provided with a second ventilation part 22 on a side close to the first ventilation part 21, the first ventilation part 21 communicating with the second ventilation part 22. That is, air may flow between the first ventilation part 21 and the second ventilation part 22, forming natural convection. When the heat pump host operates, the circuit board module 23 and the connecting terminal module 25 generate heat, and the circuit board module 23 obtains external air through the second ventilation part 22 to dissipate heat. As shown by the arrow with a broken line in fig. 3, the external air may enter the second ventilation part 22 through the first ventilation part 21, and naturally convect with the air inside the case 24 of the electric cabinet 20 to complete heat exchange, thereby radiating the heat from the circuit board module 23 and the terminal module 25. However, when the moisture content of the external air is high, too much moisture is easily accumulated at the second ventilation part 22 after the humid air having a high moisture content passes through the second ventilation part 22, which may adversely affect the normal operation of the circuit board module 23 and the terminal module 25. In order to solve the waterproof problem, the first ventilation part 21 is located at the lower side of the second ventilation part 22 such that the first ventilation part 21 and the second ventilation part 22 form a waterproof passage in the vertical direction, and when the outside air passes through the waterproof passage, the liquid of the outside air is discharged out of the waterproof passage by the gravity. The vertical direction may refer to the up-down direction shown in fig. 2 and 3. That is, the first ventilation part 21 is located entirely below the second ventilation part 22, and moisture in the air tends to sink and drip under the action of gravity, so that the moisture content in the air entering the second ventilation part 22 can be reduced, excessive moisture accumulation at the second ventilation part 22 is avoided, and the risk of water seepage is reduced.

In the embodiment shown in fig. 2, the casing 1 has a longitudinal direction, a width direction and a height direction, the longitudinal direction can refer to the direction indicated by the arrow in fig. 1, the width direction can refer to the direction indicated by the arrow in fig. 1, and the height direction can refer to the direction indicated by the arrow in fig. 1. The housing 1 comprises a second long side wall 11, a second short side wall 12, a first top plate 13 and a first bottom plate which are connected. The second long side wall 11 extends in the longitudinal direction of the casing 1, and the second short side wall 12 extends in the width direction of the casing 1. The two second long side walls 11 and the two second short side walls 12 are connected together to enclose a closed rectangular contour. Two second long side walls 11 and two second short side walls 12 are connected between the first top plate 13 and the first bottom plate, respectively, to form a rectangular parallelepiped-like housing 1. And, the electric cabinet 20 is provided at one end of the inside of the cabinet 1 in the length direction thereof.

In the embodiment shown in fig. 3 and 5, the case 24 also has a longitudinal direction, a width direction and a height direction, the longitudinal direction can be referred to as a direction indicated by an arrow in fig. 5, the width direction can be referred to as a direction indicated by an arrow in fig. 5, and the height direction can be referred to as a direction indicated by an arrow in fig. 5. The longitudinal direction of the case 24 is perpendicular to the longitudinal direction of the casing 1, and the longitudinal direction of the case 24 is identical to the width direction of the casing 1. The case 24 includes a first long side wall 241, a first short side wall 242, a second top plate 243, and a second bottom plate 244. The two second short side walls 12 are respectively connected with the first long side wall 241 and together enclose a contour similar to a "C" shape. The first long side wall 241 and the two first short side walls 242 are respectively connected between the second top plate 243 and the second bottom plate 244, and together enclose a box 24 with one open end and one closed end, and an access hole is formed at the opening of the box 24.

Therefore, the area of the first short side wall 242 excluding the vent hole forms a water deflector, and the water deflector is provided toward the first vent portion 21. When the outside air flows between the first ventilation part 21 and the second ventilation part 22, the path through which the outside air flows is increased, so that moisture in the moist outside air is blocked by the water blocking plate.

In some embodiments, the first ventilation part 21 is located entirely below the ventilation hole, i.e., the uppermost end of the first ventilation part 21 has a lower height than the lowermost end of the ventilation hole. The water blocking portion 26 prevents outside rainwater from drifting into the case 24. In other embodiments, the second venting portion 22 may also include a venting slot, a venting mesh, or the like.

In some embodiments, in order for the vent to have a sufficient amount of intake air, the area of the vent may occupy at least half of the total area of the first short side wall 242. For example, in the embodiment shown in fig. 5, the area of the vent holes is greater than half the total area of the first short side wall 242.

Further, in the embodiment shown in fig. 3, the first ventilation part 21 and the second ventilation part 22 are disposed at intervals. Specifically, the second long side wall 11 of the casing 1 and the first short side wall 242 of the case 24 are disposed at a parallel interval, so that the louver on the casing 1 and the vent hole on the case 24 are also disposed at an interval. Thereby, a cavity is formed between the first ventilation part 21 and the second ventilation part 22.

In some embodiments, the heat pump host further includes a fan (not shown) disposed between the first ventilation portion 21 and the second ventilation portion 22. Specifically, the fan may be disposed in a space formed between the louver on the cabinet 1 and the vent hole on the case 24, accelerating the flow of air and evaporation of moisture in the space, thereby avoiding accumulation of excessive moisture at the second vent portion 22.
