When the positioning protrusion 126 is inserted into the positioning groove 21, the positioning protrusion 126 can limit the electrical control box 28 from moving toward the opening of the mounting groove 122. Thus, the bottom wall 125 of the slot and the positioning protrusion 126 cooperate to limit the movement of the electrical control box 28 in the opening direction of the mounting slot 122. In addition, since the positioning groove 21 is formed in a notch shape, the groove wall of the positioning groove 21 is reduced, and thus the dimension of the electrical control box 28 reserved in the groove opening direction of the mounting groove 122 for forming the positioning groove 21 can be reduced.

To facilitate the insertion of the positioning protrusion 126 into the positioning groove 21, in an embodiment, the positioning groove 21 has an insertion opening with a flaring shape, and the positioning protrusion 126 is inserted into the positioning groove 21 from the insertion opening. Specifically, the groove wall of the positioning groove 21 may be an inclined wall 22 or an arc-shaped wall, so that the insertion opening is flared. When the positioning protrusion 126 is inserted into the positioning groove 21 from the insertion opening, the positioning protrusion 126 moves along the wall surface of the inclined wall 22 or the arc-shaped wall, and the inclined wall 22 or the arc-shaped wall has a guiding effect on the positioning protrusion 126, thereby reducing the difficulty in inserting the positioning protrusion 126 into the positioning groove 21. In other embodiments, the positioning protrusion 126 may also have an inclined or arc surface formed thereon, such that the positioning protrusion 126 tapers in circumferential dimension in a direction near its free end.

Of course, in other embodiments, the positioning protrusion 126 may be disposed on the first groove wall 123 or on the groove bottom wall 125. In addition, the positions of the positioning protrusion 126 and the positioning groove 21 can be interchanged, that is, the positioning protrusion 126 is disposed on the electrical control box 28, and the positioning groove 21 is disposed on the groove wall of the mounting groove 122.
