First, use titanium (Ti) as metal basal board, make rough surface be formed coarse by the etch processes of oxalic acid
Face.
Then, the platinum becoming metal level is divided the surface being applied to metal basal board several times, and fires and form metal level.
Then, similarly (table on the metal level being applied to be made up of platinum several times is divided tantalum pentoxide as electrode catalyst
Face), and fire and form the film of electrode catalyst.Anode electrode 6b is produced by said method.Thereby, it is possible to

Additionally, in the present embodiment, as it has been described above, anode electrode 6b passes through at the metal basal board that have employed titanium
Form tantalum pentoxide on surface to constitute as electrode catalyst.Thus, with the electrode of other structure (such as, platinum electricity
Pole etc.) compare, anode electrode 6b can utilize the area of such as 1/4 to generate the ozone of roughly the same amount.Its result
It is possible to realize electrode and the miniaturization of electrolysis bath and cost degradation.
Below, to smelly by means of the tantalum pentoxide for electrode catalyst in the anode electrode 6b of present embodiment
The structure that oxygen water generates includes illustrating speculatively.

Layer.
Then, by anode electrode 6b reaction generate electronics by tunnel-effect by being formed at tantalum pentoxide table
The depletion layer in face.Thus, current potential that electronics gives and accepts is carried out more than the oxidation-reduction potential of ozone.As a result of which it is, energy
Enough higher efficiency ground carries out the reaction of formation of ozone, it is possible to generate Ozone Water.
It addition, in the past, use the electrode catalyst that such as Lead oxide brown, diamond, platinum etc. generate as Ozone Water.
But, if lead, then misgivings can affect environment and human body.If additionally, diamond or platinum etc., then exist cost high,
The problem such as the formation efficiency of Ozone Water is low.Therefore, it is difficult to conventional electrode catalyst is applied to widely purposes with life
Become Ozone Water.
Therefore, in the present embodiment, have employed tantalum pentoxide as electrode catalyst.Compared with conventional platinum, tantalum
Oxide can generate ozone under low current density.Additionally, tantalum pentoxide has electric current density gets over the generation of low-ozone
The feature that efficiency is the highest.
Further, tantalum pentoxide has high oxygen overvoltage.Therefore, oxygen is produced the most at lower voltages, it is possible to exceeding such as
Ozone is produced under the voltage of the degree of about 1.5V.Thus, compared with conventional platinum, tantalum pentoxide can utilize 1/4
The electric power of degree generates ozone.As a result of which it is, in the case of being applied to electrical article etc., it is possible to improve joint further
Can property.
As described above, by tantalum pentoxide is used for electrode catalyst such that it is able to efficiently generate smelly

That is, CT value be sterilization or the concentration C of degerming required spike and with bacterium time of contact T long-pending.That is, CT
Being worth the least, degerming performance is the highest.
Compared with hypochloric acid water, represent that the CT value of the degerming performance of the Ozone Water of generation is little by about one in the present embodiment
More than figure place, therefore, there is high response.Therefore, Ozone Water can carry out utilizing that hypochloric acid water is difficult to carry out is low
Moment (short time) under concentration is degerming.That is, Ozone Water can have the rinse water electrolysis to sterilization unit 6 of bacterium
Groove 6a flow into and from nozzle 20 discharge before period sterilize.Furthermore it is possible to use Ozone Water maintains rinse water
Stream 202 cleans.
On the other hand, in the case of sterilizing at the hypochloric acid water of generation high concentration, in the electrolysis of rinse water,
Need electrode is applied high electric current and voltage.Therefore, it is impossible to guarantee to constitute the durability of the electrode of sterilization unit.Further,
The problem producing energy saving difference.But, according to the electrode structure of the sterilization unit of present embodiment, when generating Ozone Water,
Do not occur at the problems referred to above when generating hypochloric acid water.
Additionally, in the case of by electrolytically generated hypochloric acid water, need rinse water to contain chloride ion.Further, secondary chlorine
The amount of chloride ion that contains according to rinse water of growing amount and different.That is, bactericidal property is different according to region.Therefore,
In the case of the chloride ion contained in rinse water is extremely few, it is desirable to provide chloride ion.But, in the present embodiment,
The electrode catalyst being made up of tantalum pentoxide is formed on the surface of anode electrode 6b.Structure from the description above, sun
The electrode catalyst of pole electrode 6b efficiently generates Ozone Water.Therefore, (chlorine will not be affected by the water quality of region
The amount etc. of ion).As a result of which it is, stable bactericidal property can be obtained all the time by sterilization unit 6.
Additionally, the clean washing apparatus of present embodiment is following structure: the sterilization unit 6 with electrolysis bath 6a is set
Put the upstream side at heat exchanger 7.This is to prevent the formation efficiency of Ozone Water due to the water temperature of rinse water not
With.
Below, use Fig. 4 that the reason that the formation efficiency of Ozone Water is different because of the water temperature of rinse water is illustrated.
Fig. 4 is the water temperature chart with the relation of ozone concentration of the sterilization unit illustrating this embodiment.
As shown in Figure 4, along with the water temperature of rinse water uprises, the ozone amount dissolved in rinse water reduces, the ozone of dissolving
Concentration reduces.
Particularly, that spray from nozzle in utilization, by the hot water electrolysis of heated about 39 DEG C of heat exchanger 7
In the case of generating Ozone Water, the majority of the ozone of generation will not be dissolved in water, but is released as ozone gas.
Therefore, the ozone concentration in rinse water reduces, and degerming performance reduces.Additionally, there is also such misgivings: to cleaning
The degerming inoperative ozone gas of water is diffused in toilet space, makes troubles to user.
Therefore, in the present embodiment, the sterilization unit 6 with electrolysis bath 6a is arranged on the upstream of heat exchanger 7
Side, the rinse water electrolysis of the low temperature before being heated by heat exchanger 7.Thereby, it is possible to the ozone in raising rinse water
Concentration is to efficiently generate Ozone Water.As a result of which it is, the health being capable of having the degerming performance of excellence cleans dress
Put.
Additionally, according to above-mentioned configuration, it is possible to smelly by generate from the rinse water of low temperature by the heater of heat exchanger 7

Below, the degerming performance of the sterilization unit of structure based on present embodiment is specifically illustrated.
First, the large intestine containing such as 10000CFU (Colony Forming Unit: colony forming unit)/ml is made
The water of 20 DEG C of bacterium is flowed in electrolysis bath 6a.The water flowed into is utilized to generate about in the electrolysis bath 6a of sterilization unit 6
The Ozone Water of 0.1ppm.And then, arrange from nozzle when the power supply of the heater of heat exchanger 7 is disconnected
The degerming rate of the water gone out is evaluated.As a result of which it is, the degerming rate of coliform is 99%, the coliform of 1% fails
Remove.
On the other hand, when generating above-mentioned Ozone Water, to connecting the power supply of heater of heat exchanger 7 and making
The degerming rate of the water being raised to 39 DEG C and discharge from nozzle waterborne flowed out from electrolysis bath 6a is evaluated.As a result of which it is,
The degerming rate of coliform is more than 99.99%, at most the coliform of residual 0.01%.
According to above evaluation result, by utilizing heat exchanger 7 Ozone Water generated to be heated, thus ozone is anti-
Answering property improves.Thus, make non-degerming rate become less than 0.01% from 1% degree, improve more than 2 figure places.Its knot
Fruit it is possible to degerming performance is greatly improved.
Additionally, the clean washing apparatus of present embodiment passes through temperature sensor 8a to the electrolysis as sterilization unit 6
Rinse water before groove 6a flows into detects.And then, it is configured to: according to the temperature of the rinse water detected, logical
Cross control portion 4 voltage or electric current that put on electrode when rinse water is electrolysed are controlled.According to this structure, suppression
The change of the ozone concentration that the change of the water temperature entering into the rinse water in electrolysis bath 6a causes.As a result of which it is, can
Do not affected by the water temperature of rinse water and generated the rinse water of stable ozone concentration.
Specifically, in the case of the water temperature of the such as rinse water that temperature sensor 8a detects is 5 DEG C, control
Portion 4 is reduced by the voltage of electrolysis so that the ozone concentration in rinse water reduces.On the other hand, it it is 35 DEG C in temperature
In the case of, control portion 4 so controls: improved by the voltage of electrolysis so that the ozone concentration in rinse water rises.Thus,
Stable ozone concentration can be guaranteed all the time not against the change of water temperature.As a result of which it is, can obtain stable degerming
Performance.
Further, in order to by the generation of the ozone concentration of all-the-time stable and degerming performance long term maintenance, it is important that improve sun
