Whereas an increase in flow rate is known from bernoulli's law to be accompanied by a decrease in fluid pressure, a common venturi phenomenon. That is, this effect means that a low pressure is generated in the vicinity of the fluid flowing at a high speed, thereby generating an adsorption effect. The venturi can be made with this effect.

Therefore, when water in the drain pipe 201 is rapidly discharged to the outside through the action of the drain pump, the venturi tube 2 structure generates strong negative pressure, and the residual water is sucked to the drain pipe 201, thereby realizing the function of draining water.
