With the recent increase in airtightness and heat insulation of houses, it has become an environment where these bacteria and fungi can easily grow. It is considered that the surface of the cleaning nozzle grows after long-term use. These grown bacteria and fungi cannot be sufficiently sterilized by the nozzle cleaning operation at about 40 ° C. as described above, and an improvement in cleanliness is desired.

  For this reason, in recent years, it has been proposed to apply a chemical to nozzle cleaning (see Patent Document 2). FIG. 5 shows the sanitary washing apparatus described in the document 2. In the figure, reference numeral 1 denotes a cleaning nozzle, which has a cleaning cap 3 for performing nozzle cleaning by splashing the cleaning water from the ejection hole 2 at the ejection hole 2 and the position where the cleaning nozzle 1 is stored. A chemical tank 4 is supplied to the chemical supply path 6 by the chemical injection pump 5, and the cleaning water and the chemical liquid 9 that have passed through the original electromagnetic valve 7 and the cleaning water supply path 8 are mixed and flow into the cleaning nozzle 1 and eject The washing nozzle is washed with the chemical liquid by being ejected from the hole 2.

Further, Patent Document 2 discloses that hypochlorous acid generated by electrolyzing water as a chemical solution is applied to nozzle cleaning.
