• a liquid transfer means including a body of the liquid transfer means including a liquid pumping means provided therein with an impeller to which a motor is connected, and a plurality of distribution paths respectively formed in a tubular shape and including a first distribution path of the liquid transfer means allowing liquid to flow into and out of the body of the liquid transfer means;
• and
• a flow path change means including a body of the flow path change means provided therein with a plurality of opening/closing means, and a plurality of distribution paths respectively formed in a tubular shape and including a first distribution path of the flow path change means allowing liquid to flow into and out of the body of the flow path change means,
• wherein the liquid transfer means and the flow path change means are integrally formed with each other in such a manner that the first distribution path of the liquid transfer means and the first distribution path of the flow path change means are integrally connected to each other.
