In the waterproof wire controller 100 of the present embodiment, during assembly, the circuit board 3 and the middle end plate 4 are assembled and fixed by the fixing screw 34, the waterproof coil 2 is buried in the first groove 11 of the bottom plate 1, and then the middle end plate 4 and the bottom plate 1 are sealed and fixed by the fixing screw 46, so as to complete the first layer of waterproof; and then the waterproof adhesive film 5 and the waterproof key sleeve 6 are assembled in sequence, and finally the upper cover plate 7 and the middle end plate are fastened and fixed to finish the second layer of waterproof.

Referring to fig. 15, the present embodiment further provides a heat pump unit, which includes a heat pump unit box 200 and the waterproof wire controller 100 described above; the heat pump unit box 200 is provided with a line controller installation groove 201, and the waterproof line controller 100 is embedded in the line controller installation groove 201.

In the heat pump unit of the embodiment, on the basis of adopting the waterproof wire controller 100 to improve the waterproof performance, the waterproof wire controller 100 is embedded in the wire controller mounting groove 201, so that the waterproof wire controller 201 can be prevented from being exposed outside the heat pump unit box 100, and water inflow is further prevented.

The waterproof wire controller and the heat pump unit provided by the utility model can be used for effectively preventing water, are convenient to install, and have long service life and high safety.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that modifications and improvements can be made by those skilled in the art without departing from the spirit of the utility model, and the utility model is intended to encompass such modifications and improvements.
