Description

  The present invention relates to a water treatment apparatus, and more particularly, to a mounting structure for attaching a housing to a wall surface in a state where a connection hose is connected to the lower surface of the housing that houses the treatment unit.

  Conventionally, as shown in FIGS. 7 and 8, the water treatment apparatus 1 includes a switching unit 2 that switches raw water to a predetermined water outlet or water channel by a switching valve 7 that is attached to a faucet 6 that supplies raw water and is internally provided. In addition, there is known a configuration that includes a processing unit 3 that performs a raw water treatment separately from the switching unit 2 (see, for example, Patent Document 1). 7, the raw water from the faucet 6 reaches the treatment unit 3 through the switching unit 2 and the water supply pipe 4, and the treatment water generated by the treatment unit 3 is provided in the treatment unit 3. Water is discharged from the water outlet 29. On the other hand, in the water treatment apparatus 1 of FIG. 8, the raw water from the faucet 6 reaches the treatment unit 3 from the switching unit 2 through the water supply pipe 4, and the treated water generated in the treatment unit 3 passes through the water supply pipe 5. Returning to 2, water is discharged from the treated water outlet 29 provided in the switching unit 2.

  By the way, in the water treatment apparatus 1 in which the switching unit 2 and the processing unit 3 are separated as described above, the switching unit 2 is attached to the faucet 6, and the housing 39 in which the processing unit 3 is housed is installed at the counter corner near the sink. It is installed in the department. In addition, since the housing 39 is merely stationary, the housing 39 is easy to move when operating the operation portion of the housing 39, and in particular, the connection constituting the water supply pipe 4 and the water supply pipe 5 from the lower surface of the housing 39. Since the hose is drawn, there is a problem that the stability of the lower surface 39c of the housing 39 is impaired by the connection hose. Furthermore, since an electric cord (not shown), an operation unit, a display unit and the like wired to the electrolytic cell are easily wetted with water, a special waterproof structure is required. In addition, since it is necessary to secure an installation space for the housing 39 in the counter corner near the sink, there is a problem that the space in the counter corner near the sink is occupied by the housing 39.

  Therefore, another conventional example has been proposed in which the housing 39 that houses the processing unit 3 is locked to a wall. As an example, a hook is attached to the wall of the kitchen, a locking hole (for example, a darling hole) is formed on the back surface of the housing 39, and the housing 39 is locked to the wall by hooking the locking hole on the hook. It is.

However, in such a locking structure, since the locking hole is disposed on the back surface of the housing 39, it is difficult to align the locking hole on the back surface of the housing 39 and the hook when locking the housing 39 to the hook. It is difficult to install. Moreover, since it is common to replace the water purification cartridge or the like from the rear surface of the housing 39, the housing 39 must be removed and attached every time the maintenance of the processing unit 3 is performed, which is inconvenient. Met.
