  On the other hand, when the user removes and operates the switching unit 3 from the operation unit 6, the operation of the switching lever 12 of the switching unit 3 is the same as described above, and the user removes the operation unit 6 from the switching unit 3. Install in a place that is easy to carry or operate.

  At this time, for example, if a magnet and a suction cup (both not shown) are provided on the back surface of the operation unit 6, the operation unit 6 can be easily fixed to the installation location.

  Next, a water quality setting button 14 provided on the operation unit 6 is pressed to set a predetermined water quality (here, alkali is selected as an example).

  At this time, the content set by the water quality setting button 14 is transmitted to the transmission control unit 32, and the transmission control unit 32 transmits the content set by the transmission unit 7 by a radio signal.

  The radio signal transmitted from the transmission unit 7 is received by the reception unit 9 of the post-processing apparatus main body 2 after being relay-reflected on the ceiling 8a.

  Here, even if tableware or the like is placed between the switching unit 3 and the processing apparatus main body 2, the radio signal is transmitted and received by relay reflection of the ceiling 8a, so that the radio signal is always transmitted and received reliably. can do. About subsequent operation | movement, it is the same as that of the above-mentioned case which operates in the state which attached the operation part 6 to the switching unit 3. FIG.

  Therefore, when the operation unit 6 is detached from the switching unit 3 and operated, the user can carry the operation unit 6 or install and operate it in the most convenient place. Can be significantly increased.

  Further, since the battery 16a is used for the power source of the operation unit 6, it is not necessary to connect a power cord or the like to the operation unit 6, so that the operation unit 6 can be carried freely and the installation location of the operation unit 6 can be reduced. Restrictions can be reduced.

  When weak acidity is selected with the water quality setting button 14 of the operation unit 6, weakly acidic ionic water is discharged from the water outlet 31 and alkaline ionized water is discharged from the drain hose 5. If purified water is selected with the water quality setting button 14, no electrolytic voltage is applied to the electrolytic cell 37, and purified water is discharged and drained from both the water outlet 31 and the drain hose 5.

  Further, in this example, the processing apparatus main body 2 is operated by the operation unit 6, but for example, the user is closer to the processing apparatus main body 2 than the operation unit 6 removed from the switching unit 3 and installed in another place. If it is, the water quality setting button 17 provided in the processing apparatus main body 2 may be used to set the water quality to a predetermined level.

  Even when the reflection plate 8 b is the reflection unit 8, the radio signal transmitted from the transmission unit 7 of the switching unit 3 is relayed and reflected by the reflection plate 8 b directed in an arbitrary direction, and then received by the reception unit 9. The As described above, in this example, since the reflecting plate 8b whose orientation can be changed is installed as the reflecting portion 8, for example, when the ceiling 8a above the switching unit 3 and the processing apparatus body 2 is a material that is difficult to relay and reflect a radio signal, Even when it is very high and not suitable for relay reflection of a radio signal, the radio signal transmitted from the switching unit 3 can be reliably received by the receiving unit 9 of the processing apparatus body 2 using relay reflection. Further, since the direction of the reflecting plate 8b can be changed, the direction of the reflecting plate 8b can be finely adjusted so that the radio signal from the transmitting unit 7 can be received more reliably by the receiving unit 9.

  The reflector 8b is not only used when the ceiling 8a hardly reflects the radio signal due to the material of the ceiling 8a, the height of the ceiling 8a, etc. as described above, but also in a state where the ceiling 8a can be used as the reflecting portion 8 to transmit the radio signal. May be used. Further, although the front surface of the mirror 52 serving as a reflection surface is a concave surface, it may be a flat surface. In addition, the reflecting surface of the reflecting plate 8b is composed of the mirror 52. However, if the material or color easily reflects the radio signal, the reflecting surface is configured by using a cloth such as a resin plate or nylon instead of the mirror 52. May be. In the embodiment described above, the reflecting portion 8 is a ceiling 8a or a reflecting plate located above the switching unit and the processing apparatus main body. However, the reflecting portion 8 may be a lower surface portion of a top bag or the like. Moreover, although infrared rays were used as a radio signal in any of the embodiments, the radio signal may be, for example, an ultrasonic wave or a weak radio wave.
