[0031] As Figures 1 to 14 Indicated, it is a kind of block type electric control box structure for heat pump, including:

[0032] Installation frame 1, there is support frame 4 on the installation frame 1;Its characterized in that further include: electric control box 6 and electric control box cover group, the electric control box 6 is installed at installation frame 1, and is located at the rear of support frame 4, the electric control box cover group includes multiple covers, multiple the cover can be detachably installed at the opening of electric control box 6 and is located at the rear of support frame 4, one of the cover of electric control box cover group is shielded in front direction by support frame 4.

[0033] In use, the electric control box cover assembly can be disassembled in blocks, so that the support frame 4 can be opened and avoided.

[0034] In this embodiment, the electric control box cover assembly includes two side cover plates 2 and a middle cover plate 3, which are detachably installed at the opening of the electric control box 6, and the two side cover plates 2 are respectively located on the left and right sides of the middle cover plate 3. The middle cover plate 3 is located at the back of the support frame 4 and is shielded by the support frame 4. The left and right length dimensions L1 of the middle cover plate 3 are greater than the left and right length dimensions L2 of the support frame 4, and the front and back thickness dimensions W1 of the middle cover plate 3 are less than the front and back distance W2 between the support frame 4 and the electric control box 6. In use, in this way, the middle cover plate 3 can be disassembled by first disassembling the fixing member, then moving forward, and then moving left and right.

[0035] In this embodiment, the upper part of the opening of the electric control box 6 is provided with a mounting surface 62 and an upwardly open drainage groove 63. The mounting surface 62 is the front side arm of the drainage groove 63, and the two side cover plates 2 and the middle cover plate 3 are respectively installed on the mounting surface 62. The upper part of the two side cover plates 2 is provided with a rear side hanging plate 21, and the upper part of the middle cover plate 3 is provided with a rear middle hanging plate 31. The edges of the two side hanging plates 21 and the middle hanging plate 31 are located directly above the drainage groove 63. In use, the side cover plates 2 and the middle cover plate 3 are respectively installed on the mounting surface 62, which is convenient for installation. The edges of the side hanging plates 21 and the middle hanging plate 31 are located directly above the drainage groove 63, which ensures that the water droplets existing on the side hanging plates 21 and the middle hanging plate 31 fall into the drainage groove 63, avoiding the short circuit of the electric control due to water.

[0036] In this embodiment, the middle section of the mounting surface 62 is concave in the rear direction. The middle cover plate 3 is installed on the middle section of the mounting surface 62, and the two side cover plates 2 are respectively installed on the left and right sections of the mounting surface 62. In this way, after the two side cover plates 2 are installed, they are located in front of the middle cover plate 3, and when the side cover plates 2 are disassembled, the middle cover plate 3 does not need to be disassembled first.

[0037] In this embodiment, the edges of the two side hanging plates 21 are provided with downward upper water guide plates 22, which are located directly above the drainage groove 63. The upper water guide plates 22 not only strengthen the strength of the side cover plates 2, but also increase the drainage performance.

[0038] In this embodiment, the lower part of the two side cover plates 2 is provided with a downward lower water guide plate 23 in the rear direction. The lower water guide plate 23 not only strengthens the strength of the side cover plates 2, but also avoids the back splash of the water droplets below.

[0039] In the embodiment, the two lower water guide plates 23 and the middle cover plate 3 have gaps in the front-rear direction, and the two upper water guide plates 22 and the middle cover plate 3 have gaps in the up-down direction, and the gaps are 1-3 mm. In use, the two side cover plates 2 can slide left and right relative to the middle cover plate 3 after being disassembled, so that the electrical components in the electric control box 6 can be maintained; the gap is 1-3 mm, which ensures smooth sliding and minimizes dust entering the electric control box 6.

[0040] In the embodiment, the wire blocking plates 31 are arranged on the left and right sides of the middle cover plate 3, and the wire blocking plates 31 are located on the rear side of the middle cover plate 3. The two side cover plates 2 are fixedly connected to the middle cover plate 3 by screws, and the wire blocking plates 31 shield the rear side of the screws. This avoids damage to the internal electric control wires by the screws.

[0041] In the embodiment, the rain blocking plate 61 is arranged on the upper part of the electric control box 6 and above the drain groove 63. The rain blocking plate 61 avoids water from directly falling into the drain groove 012, thereby reducing the drainage pressure. The distance Y1 between the rain blocking plate 61 and the two side cover plates 2 in the up-down direction is greater than the height dimension Y2 of the upper water guide plate 22, which facilitates disassembly of the two side cover plates 2. The front-rear thickness dimension X1 of the rain blocking plate 61 is greater than the front-rear thickness dimension X2 of the two side hanging plates 21, thereby avoiding water from directly falling into the drain groove 012 to the greatest extent.

[0042] The low-failure components are arranged in the middle part of the electric control box 6, and the other components are arranged on the left and right sides. The left side is the control board and its wiring terminal, the right side is the drive board and its wiring terminal, and the middle part is the filter board and the like.

[0043] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the described embodiments. For ordinary skilled persons in the art, various changes, modifications, replacements and deformations of the embodiments without departing from the principles and purposes of the utility model still fall within the protection scope of the utility model.
