  When the switching lever 16 is operated so that the switching mechanism discharges the raw water from the raw water discharge port 13, the raw water supplied from the faucet is caused to enter the body 12 of the main body 10 and a predetermined portion of the switching mechanism. Then, the raw water can be discharged in a straight shape or a shower shape from the raw water discharge port 13.

  On the other hand, when the switching lever 16 is operated and the switching mechanism is in a state of sending raw water from the raw water outlet 141, the raw water supplied from the faucet enters the inside of the body 12 of the main body 10 and the switching mechanism After passing through a predetermined part and passing through the raw water delivery path 15, it is sent out from the raw water delivery outlet 141. The raw water sent through the raw water outlet 141 is supplied from the raw water inlet into the cartridge unit 20. The raw water supplied to the cartridge unit 20 can be purified by filtering it through a filter medium and discharged as purified water from a purified water discharge port.

  In this way, when the raw water from the faucet is sent to the cartridge unit 20 and the raw water is purified and discharged as purified water by the cartridge unit 20, the water wheel 151 rotates according to the raw water passing through the raw water delivery path 15, The flow rate sensor 33 detects the change in the magnetic field due to the rotation of the water turbine 151 to detect the flow rate, and gives a detection signal to the control unit 34. The control unit 34 to which the detection signal is given calculates the integrated flow rate value and gives an output signal to the liquid crystal display 35, and the liquid crystal display 35 displays the integrated flow rate value.

  Then, by moving the electrical unit 30 upward relative to the main body 10, the engaging convex portion 312 is detached from the engaging concave portion 18 and the protruding portion 311 is detached from the groove portion 17. Thus, the electrical unit 30 can be removed from the main body 10. That is, the electrical unit 30 is unitized by disposing each electrical component that detects the flow rate of raw water sent from the main body unit 10 to the cartridge unit 20 and displays the integrated flow rate value in the common unit main body 31. The main body 10 is detachably disposed. By removing only the electrical unit 30 in this way, when there is a malfunction in the electrical component of the electrical unit 30, only the electrical unit 30 can be sent for repair, and the main body 10 remains attached to the faucet, It is possible to use purified water. Further, it becomes possible to purchase a new electrical unit depending on the degree of malfunction of the electrical unit 30 and to newly attach the purchased new electrical unit to the main body unit 10.

  As described above, according to the water purifier of the present embodiment, each electrical component that detects the flow rate of raw water sent from the main body 10 to the cartridge unit 20 and displays the accumulated flow value is a common unit. Since the electrical unit 30 formed as a unit by being disposed in the main body 31 is detachably disposed with respect to the main body unit 10, by removing only the electrical unit 30 when an electrical component breaks down, It is possible to continue to use the purified water during the repair period of such electrical components, and to avoid purchasing a new product.
