FIG. 2 shows a control circuit section of the control means 11. 13
Microcomputer (hereinafter referred to as microcomputer), 14
1 is a ladder circuit, and 15 is a comparator, which converts the signal from the sensor 7 and the setting value from the setting means 10 into analog to digital, and inputs the converted signal to the microcomputer 13. 16 is a cleaning switch, and when the microcomputer 13 detects that the cleaning switch 16 is turned on, it energizes the pump 6 and starts energizing the pump 280.

FIG. 3 is a schematic flow diagram of control of a conventional sanitary cleaning device. This will be explained in conjunction with the control circuit diagram shown in FIG.

First, the microcomputer 13 checks whether the cleaning switch is turned on (cleaning starts).

(Stop 3 1).

If it is turned on, the microcomputer 13 energizes the pump 6 (Step 32), converts the set value of the setting means 10 into eight-way conversion by the ladder circuit 14 and comparator 15, and inputs it to the microcomputer 13. (Step 3-3).

Next, in the same manner, the signal from the sensor 7 is converted from analog to digital and input to the microcomputer 13. (Stop 3 4) The microcomputer 13 constantly monitors the signal from the sensor 7 and the set value of the setting means 10, and controls the amount of electricity supplied to the heater 8 so that the temperature of the cleaning water reaches the set value. . (Stop 3
5). Next, the microcomputer 13I''i checks whether the cleaning is finished (Step 3'-6), and if it is not finished, the process is repeated at step 7.
Then, the process returns to Step 32 and repeats the same control sequence. If cleaning is completed, the pump is de-energized and the heater is also de-energized (Step 3 7)
).

Note that there is a means of using a washing stop switch (not shown in FIG. 2) or a timer of the microcomputer 13 to finish the washing.

Therefore, in conventional sanitary cleaning devices, the temperature of the cleaning water set by the setting means is always discharged.

However, in the above-mentioned conventional configuration, if the previous user sets the setting value of the setting means 10 to a high value and finishes, the next user turns on the cleaning switch 16 and immediately sprays hot cleaning water on the private parts. When the user has to bathe in the water, the user feels uncomfortable and abrupt, and has to operate the setting means 10 again to set the temperature of the washing water to the user's preference. This means that the temperature of the washing water that the general user feels comfortable with is extremely variable, and the setting means 1
While it is common practice to operate the setting of 0, there are some users who operate the setting means 10 to change the temperature of the washing water depending on the user's local condition or the user's preferences. Users often leave the settings on the setting means as they are and fail to finish cleaning, which causes the next user to feel uncomfortable, abrupt, and troublesome, as described above.

OBJECTS OF THE INVENTION The present invention solves these conventional drawbacks, and aims to improve the operability of the setting means by emitting a temperature of washing water that is comfortable for general users without having to operate the setting means at the start of washing. It is an object of the present invention to provide a sanitary washing device that not only improves the user's comfort but also allows the user to instantly obtain the temperature of washing water that suits his or her preference.

Structure of the Invention In order to achieve this object, the present invention controls the temperature of the cleaning water to a predetermined value regardless of the setting value when the setting means for setting the temperature of the purified water during cleaning is not operated, and Control that controls the temperature of the wash water according to the set value when the means is operated.With this configuration, when cleaning starts, a predetermined temperature of the wash water is obtained regardless of the set value of the setting means. has.

DESCRIPTION OF THE EMBODIMENTS The configuration and control circuit diagram of the sanitary cleaning device applied to the present invention are the same as the members in FIGS. 1 and 2 shown in the conventional configuration example, and are designated by the same numbers. This is the one that will be adopted.

FIG. 4 is a schematic flow diagram of control in one embodiment of the present invention. This will be explained in conjunction with the control circuit diagram shown in FIG.

In the above configuration, the microcomputer 13 first resets the pass flag and the setting flag.

(Step 4-1). This is for storing the initial setting value of the setting means at the start of cleaning.

Next, the microcomputer 13 checks whether the cleaning switch 16 is turned on (cleaning start), and if it is turned on (Step 42), it checks whether the pass flag is set. (Step 4 3). At first, the passing flag is reset, so the microcomputer 13 (Step 4)
Go to and energize the pump. Then, the set value of the setting means is A-D converted via the ladder circuit 14 and the comparator 15,
(Step 4 5), memorize. , (Step 4 6
), and the signal from the sensor 7 is similarly analog-to-digital converted. (Step 4-7) At this time, the microcomputer 13 monitors the signal from the sensor 7 so that the cleaning water temperature reaches a predetermined value, for example, 40'C, regardless of the setting value set by the setting means. Controls the amount of electricity supplied to the heater 8.

(Step 4 s) Then set the passage flag 5t
OP-19) Check the completion of cleaning.

(Step 4 10) If not finished, repeat (Step 4 10).
Return to Step 4-3) and confirm the passing flag set.

This time, since the pass flag has been set, the process proceeds to the setting means operation check routine (Step 411). The setting value of the setting means 1o is A-D converted, and (Stop
4 12 ), the set value is compared with the stored value of the setting of the first setting means in (Step 4-5).

(Step 4-13), Check if the microcomputer 13 matches. 5top 4-14) If they match, check if the setting flag is set, and now it is reset. (Step 4-7) ).

Therefore, unless the setting means is operated, the setting value is always the same value. Therefore, the microcontroller was

The microcomputer 13 repeats the control sequence of "P4-10)-" (Step 43), so that once the setting means is operated, the microcomputer 13 controls the temperature of the cleaning water to the set value from then on. When the cleaning is completed, the pump is de-energized and the heater is de-energized (Step 4-19). I'll omit it because it's similar.

Effect of the invention According to the sanitary cleaning device of the present invention, the following effects can be obtained.

Whenever you start cleaning, even if the setting means is set high, it releases cleaning water at a predetermined temperature that is comfortable for general users, especially those with delicate mucous membranes in the anal area. To prevent discomfort and sudden sensation without being bathed in hot washing water. However, if the user is satisfied with washing water at a predetermined temperature, there is no need to operate the setting means, and the hassle is eliminated. Furthermore, by operating the setting means, the temperature of the washing water desired by the user can be obtained immediately, so that it has versatility so that all people can use it comfortably, regardless of the user's local condition.
