And then, under the situation of the state continuance of the rinse water of control circuit 12 in not using water tank 3 than (for example 1 week) more than the scheduled time (the 2nd setting-up time) of above-mentioned the 1st setting-up time length, carry out following control: in the time next rinse water will being used, be not to be used for human body and the cleaning that is used for washer jet 8 at first, and just be returned as common utilization after this.

Under this situation, the rinse water of about 20% in the water tank for example 3 can be used for the cleaning of washer jet 8.

Next, about the effect of above-mentioned formation, the limit describes with reference to Fig. 6 limit.Following explanation has been carried out in the front: in the warm water wash toilet seat 1 of above-mentioned formation, even the water in the water tank 3 are the water purification of the cleaning that is supplied to, but owing to heat by hot water calorifier 26, the assorted mushroom that trace comprises (Pseudomonas aeruginosa and/or Serratieae etc.) also may be bred.

, in the present embodiment, in the water tank 3 that stores rinse water, configuration places boxlike bactericidal device 35 in housing 36 with bacteria remover 37.Thus, because in the continuous rinse water that slowly is dissolved in the water tank 3 of the degerming composition of bacteria remover 37 (for example silver ion),, can provide clean rinse water so can suppress to the breedings of assorted bacterium in the water tank 3 always.

Under this situation, the employed bacteria removers 37 of boxlike bactericidal device 35 are owing to adopt slow release glass solid solution, though (for example several years～10 years degree) continues to use between can be for a long time, if continue to use, and then eventually can approach exhaustion and reach the state of necessary replacing.

At this moment, because boxlike bactericidal device 35 can take off from the outside, so when bacteria remover 37 consumes etc., can easily be replaced by new boxlike bactericidal device 35 (perhaps bacteria remover 37 being carried out supply) from water tank 3 taking-ups.

In the present embodiment, because being assembled into bolt member 39, boxlike bactericidal device 35 is provided with, so by the switching work of bolt member 39, also can carry out the mounting or dismounting of boxlike bactericidal device 35, even the user also can easily carry out replacing (mounting or dismounting) operation of boxlike bactericidal device 35.

Different with the situation that boxlike bactericidal device 35 is set separately, because outfall 38 can be also used as the erection opening of boxlike bactericidal device 35, so also needn't can make to constitute simply in water tank 3 perforate separately.

At this, make the dissolution mechanism of degerming composition, bacteria remover concentration change just because of the temperature of rinse water sometimes in the above-mentioned bacteria remover 37, the temperature of rinse water is high more, and the degerming composition is big more to the dissolubility of water.

In addition, in the present embodiment, boxlike bactericidal device 35 is positioned near the thermistor 27 of rinse water temperature control usefulness and is provided with.Thus, the rinse water temperature around the boxlike bactericidal device 35 keeps certain substantially by design temperature.

Thereby, the bacteria remover concentration in the rinse water can be remained substantially necessarily, can access stable degerming performance, and can make the life-span of bacteria remover 37 also stable.

In addition, in above-mentioned warm water wash toilet seat 1, because of being usage frequency difference such as between communal bathroom or general household sanitary, under the lower for example situation between household sanitary of usage frequency, also produce long-term between (for example several days) do not use the situation of rinse water.

At this moment, especially at the design temperature of rinse water than under the condition with higher, the degerming composition of bacteria remover 37 is dissolved in the water tank 3 with might exceeding needs.That is to say, do not using under the situation of rinse water for a long time, because residue in assorted bacterium death ray almost in the water tank 3, so needn't make the degerming constituent concentration in the rinse water so high.

And, if do not use the degerming constituent concentration in rinse water, the rinse water to become for a long time than higher, then especially comprise under the situation of calcium phosphate at bacteria remover 37, the hydrogen ion concentration pH of rinse water descends, if this rinse water is used for cleaning, then for the people that partly there is inflammation in for example anus, might cause stimulation.

So, in the present embodiment, in order to eliminate so undesirable condition, when control circuit 12 does not use when rinse water, by controlling with the step shown in the flow chart of Fig. 6.

That is, in step S1, in the cleaning of having confirmed to be undertaken (use of rinse water) afterwards, carry out (beginning) timework (step S2) by washer jet 8.Then, under the state that does not use rinse water, judge whether this state has passed through the 1st setting-up time (for example 2,3 days) (step S3).

If continuously unused time be the 1st setting-up time with interior (being "No" in step S3), then continue the timework of step S2.Also have,, in the way of the circulation of this step S2, S3, exist under the situation of cleaning (use of rinse water), skip (resetting) timework though do not illustrate.

Surpass under the situation of the 1st setting-up time (being "Yes" in step S3) at continuous unused time, next, make the control (step S4) of the mandatory reduction of design temperature of rinse water.Under this situation, for example, design temperature is reduced to minimum temperature (20 ℃).

At this constantly, it is enough high that the degerming constituent concentration in the water tank 3 in the rinse water becomes, and the assorted bacterium that residues in the water tank 3 is dead substantially.Thereby, by forcibly reducing design temperature, can be dissolved in the degerming composition of later bacteria remover 37 in the water tank 3 with exceeding needs and become this situation of high concentration and suppress, correspondingly can prolong the life-span of bacteria remover 37.

Then continue timework (step S5), in next step S6, judge whether the unused time of rinse water surpasses the 2nd setting-up time (for example 1 week).

If continuously unused time be the 2nd setting-up time with interior (being "No" in step S6), then continue the timework of step S5.Under this situation,, in the circulation way of this step S5, S6, exist under the situation of cleaning (use of rinse water), skip (resetting) timework and make design temperature restore though do not illustrate.

And, surpass under the situation of the 2nd setting-up time (being "Yes") the later processing of execution in step S7 afterwards in step S6 at continuous unused time.In this is handled, monitor take a seat (the step S7) of user to toilet seat 4 by human perception sensor 7.And, (in step S7, be "Yes") when detecting when taking a seat, make the design temperature of rinse water restore (step S8), and carry out the nozzle cleaning work (step S9) that the part (about 20%) that makes the rinse water in the water tank 3 is cleaned from the outlet opening ejection, to washer jet 8 by nozzle cleaning pipe 34.

After this, carry out additional (the step S10) of water (tap water) in water tank 3, the bacteria remover of dilution rinse water.Based on user's operation, carry out buttocks and clean or clean cloudy cleaning (step S11).

At this, in water tank 3, bacteria remover concentration becomes and at first is used for the cleaning of washer jet 8 than the part of higher rinse water, then, the state by making its reduction of bacteria remover concentration ratio, does not just stimulate user's rinse water, carries out private parts and cleans.

Thereby, do not waste the rinse water in the water tank 3 yet, can the rinse water that bacteria remover concentration is high be not used in buttocks cleaning partly again.

So according to present embodiment, then because boxlike bactericidal device 35 is installed the water tank 3 that stores rinse water in, breed so can suppress water tank 3 interior assorted bacterium by bacteria remover 37, can supply with can relieved use rinse water.

And, can access the effect of following excellence: run out of at bacteria remover 37 under the situation of (reaching the life-span), can easily boxlike bactericidal device 35 be taken off, carry out the replacing (supply of bacteria remover 37) of boxlike bactericidal device 35 from the outside.

Because bacteria remover 37 can supply, therefore can make 35 of boxlike bactericidal devices as small-sized, and can not use bacteria remover 37 lavishly certainly.

Especially in the present embodiment, because constitute: make boxlike bactericidal device 35 be assembled into the bolt member 39 that can stop up the outfall 38 of water tank 3 with opening and closing, so the structure of water tank 3 can be simple, the user can easily carry out the mounting or dismounting operation of boxlike bactericidal device 35.

And, because the thermistor 27 of rinse water temperature control usefulness is disposed near the boxlike bactericidal device 35, so can remain certain design temperature around the boxlike bactericidal device 35, the concentration that can make bacteria remover 37 be dissolved in rinse water is certain, obtains stable degerming performance.

And, in the present embodiment,, design temperature is reduced, so can prolong the life-span of bacteria remover 37 because under the situation more than the state continuance certain hour of the rinse water in not using water tank 3 (the 1st setting-up time).

And then, because under the situation more than state continuance the 2nd setting-up time of the rinse water in not using water tank 3, in the time then will using rinse water, carry out and be not used in human body and be used for the control of the cleaning of washer jet 8, become and be used for the advantage that buttocks partly cleans, can not utilize rinse water lavishly than higher rinse water so can also obtain not concentration with bacteria remover 37.
