In a water purifier, a flow system includes a first channel in which liquid is filtrated in at least one of a first filter tank and a second filter tank, a second channel in which the liquid is filtrated in the second filter tank and the first filter tank is washed, and a third channel in which the liquid is filtrated in the first filter tank and the second filter tank is washed. A switching lever actuates valve mechanisms to perform switching among the first, second, and third channels such that the channels are selected cyclically in order of the first channel, the second channel, the first channel, the third channel and the first channel. The valve mechanisms work with operation of the switching lever. |

1. A water purifier, comprising:
a first filter tank and a second filter tank for filtrating liquid; a flow system including, at least, a first channel in which the liquid is filtrated in at least one of the first filter tank and the second filter tank, a second channel in which the liquid is filtrated in the second filter tank and the first filter tank is washed, and a third channel in which the liquid is filtrated in the first filter tank and the second filter tank is washed; a plurality of valve mechanisms configured to be opened and closed so as to perform switching among the first, second, and third channels; and a switching portion configured to actuate the plurality of valve mechanisms to perform the switching among the first, second, and third channels such that the channels are selected cyclically in order of the first channel, the second channel, the first channel, the third channel and the first channel, the switching portion being operated by a user of the water purifier, each of the valve mechanisms working in junction with the operation of the switching portion. |
