Abstract

A sanitary washing device includes: a nozzle configured to wash a local region of a human body; a tank configured to accommodate a sterilizing agent, a sterilizing component of which is dissolved into liquid, and to store supplied liquid therein; a nozzle washing unit configured to wash the nozzle using liquid supplied from the tank; and a buffering unit disposed between the sterilizing agent and an inner wall of the tank inside the tank and having liquid permeability.

First claim

What is claimed is:

1. A sanitary washing device comprising:
a nozzle configured to wash a local region of a human body;
a tank configured to accommodate a sterilizing agent, a sterilizing component of which is dissolved into liquid, and to store supplied liquid therein;
a nozzle washing unit configured to wash the nozzle using liquid supplied from the tank; and
a buffering unit disposed between the sterilizing agent and an inner wall of the tank inside the tank and having liquid permeability,
wherein the buffering unit has a bag shape that encloses the sterilizing agent, and
the buffering unit is disposed in the tank in a folded state.

2. The sanitary washing device according to claim 1 ,
wherein the tank has an outlet port that discharges the liquid toward the nozzle washing unit,
the buffering unit has a mesh shape, and
the buffering unit has a mesh opening area smaller than an opening area of the outlet port.

3. A sanitary washing device comprising:
a nozzle configured to wash a local region of a human body;
a tank configured to accommodate a sterilizing agent, a sterilizing component of which is dissolved into liquid, and to store supplied liquid therein;

the buffering unit has a mesh shape, and
the buffering unit has a mesh opening area smaller than an opening area of the outlet port.

4. The sanitary washing device according to claim 1 ,
wherein the tank has an outlet port that discharges the liquid toward the nozzle washing unit,
the buffering unit has a mesh shape, and
the buffering unit has a mesh opening area greater than or equal to an opening area of the outlet port.

5. A sanitary washing device comprising:
a nozzle configured to wash a local region of a human body;
a tank configured to accommodate a sterilizing agent, a sterilizing component of which is dissolved into liquid, and to store supplied liquid therein;
a nozzle washing unit configured to wash the nozzle using liquid supplied from the tank; and
a buffering unit disposed between the sterilizing agent and an inner wall of the tank inside the tank and having liquid permeability,
wherein the buffering unit is disposed in the tank in a folded state,
