Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sanitary cleaning device that performs cleaning by discharging cleaning water into private parts of the human body.

Configuration of Conventional Example and Its Problems An example of the configuration of such a sanitary cleaning device will be explained with reference to FIGS. 1 and 2. 1 is a toilet bowl, 2 is a cistern that stores water for flushing the inside of the toilet bowl 1, and 3
1 is a toilet seat installed on the toilet bowl 1; 4 is a cleaning nozzle for discharging cleaning water to the private parts of the human body sitting on the toilet seat 3; 5 is a water filter submerged in the water storage in the cistern; A pump sucks water from the filter and sends it under pressure to the cleaning nozzle 4; 7 is a sensor that detects the temperature of the cleaning water; 8 is a heater that heats the cleaning water pumped by the pump 6; 9 is the heat of the heater 8; This is a heat exchanger that transfers water to the washing water being pumped and heats it instantaneously. Reference numeral 10 indicates a setting means for setting the temperature of the washing water, and reference numeral 11 indicates energization of the heater 8 according to the signal from the sensor 7 and the setting value of the setting means, so that the desired temperature of the washing water can be immediately obtained and the washing can be performed. At times, the pump 9 is energized by a control means, and 12 is a storage box that houses the pump 6, the control means 11, etc. installed at the rear of the toilet seat 3.

FIG. 2 shows a control circuit section of the control means 11. A microcomputer 13 (hereinafter referred to as a microcomputer), 14 a ladder circuit, and 15 a comparator convert the signal from the sensor 7 and the set value of the setting means 10 into digital signals and input them to the microcomputer 13. 16 is a cleaning switch, and the microcomputer 13 is a cleaning switch 16.
When it is detected that the pump 6 is turned on, the pump 6 is energized and the heater 8 starts to be energized.

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 has been turned on (cleaning has started).
(Step 3-1).

If it is turned on, the microcomputer 13 energizes the pump 6 (Step 3-2), converts the set value of the setting means 10 into A/D using the ladder circuit 14 and the 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. (Step 3-4) Then, the microcomputer 13 receives the signal from the sensor 7 and the setting means 1.
The set value of 0 is constantly monitored, and the amount of electricity applied to the heater 8 is controlled so that the temperature of the cleaning water reaches the set value. (Step 3-5). Next, the microcomputer 13 checks whether the cleaning has been completed (Step 3-6), and if not, returns to (Step 3-2) and repeats the same control sequence. If cleaning has been completed, the pump is de-energized and the heater is also de-energized (Step 3-7).

To complete the cleaning, there is a means of using a cleaning stop switch (not shown in FIG. 2) or a timer of the microcomputer 13. Therefore, in the conventional sanitary cleaning device, 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 ends the operation, the next user turns on the washing switch 16 and immediately pours hot washing water into 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, which is a hassle. This means that the temperature of the washing water that the general user feels comfortable using is almost fixed, and while it is rare for the user to adjust the setting of the setting means 10, there are some Some users operate the setting means 10 to change the temperature of the washing water depending on the situation or user preference, and such users generally leave the settings on the setting means as they are and finish washing. As mentioned above, this gives the next user a sense of discomfort and abruptness.

OBJECT OF THE INVENTION The present invention solves such conventional drawbacks by emitting a temperature of washing water at which a general user feels comfortable without having to operate the setting means at the start of washing, thereby making the setting means easy to operate. It is an object of the present invention to provide a sanitary washing device that not only improves the quality of washing but also allows users to instantly obtain the temperature of washing water that suits their preferences.

Structure of the Invention In order to achieve this object, the present invention controls the temperature of the washing water to a predetermined value regardless of the set value when the setting means for setting the temperature of the washing water during washing is not operated, and The apparatus has a control means that controls the temperature of the washing water according to a set value when the means is operated.

With this configuration, at the start of cleaning, a predetermined temperature of the cleaning water can be obtained regardless of the setting value of the setting means.

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 given the same numbers. It will be adopted as is.

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 time of starting cleaning.
Next, the microcomputer 13 checks whether the cleaning switch 16 is turned on (cleaning has started) and (Step 4-
2) If it turns on, check whether the pass flag is set. (Step 4-3). Initially,
Since the pass flag has been reset, microcontroller 1
Step 3 proceeds to (Step 4-4) and energizes 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),
Remember. (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 sends the heater 8 to the heater 8 based on the signal from the sensor 7 so that the cleaning water temperature reaches a predetermined temperature, for example, 40°C, regardless of the setting value initially set by the setting means. Controls the amount of energization.
(Step 4-8) Then, the passage flag is set (Step 4-9), and the completion of cleaning is checked. (Step 4
-10), if it is not completed, return to (Step 4-3) again and confirm the passing flag set. Next time,
Since the pass flag has been set, the process advances to the setting means operation check routine (Step 4-11). The setting value of the setting means 10 is converted from A to D, and (Step 4-
12) Compare the set value with the stored value of the setting of the first setting means in (Step 4-5). (Step 4−
13), the microcomputer 13 checks whether they match (Step 4-14), and if they match, checks whether the setting flag is set, and since it has now been reset, proceeds to (Step 4-7). Therefore, unless the setting means is operated, the setting value is always the same value. Therefore, the microcomputer at that time (Step4-3) → (Step4-11) → (Step4-12)
→ (Step4−13) → (Step4−14) → (Step4−
15) → (Step4-7) → (Step4-8) → (Step4
-9) → (Step 4-10) → (Step 4-3) control sequence is repeated until the end of cleaning to obtain a predetermined cleaning water temperature that is independent of the settings.

Now, if the user operates the setting means, the set value will change, so it will not match the first set value stored in (Step 4-6). Therefore, the microcomputer 13 then uses the sensor 7 to set the temperature of the cleaning water to the set value when the setting means is operated.
The signal is A-D converted (Step 4-16) and the heater 8
Controls the amount of electricity applied to the (Step 4-17) Then, set the setting flag (Step 4-18), check the completion of cleaning (Step 4-10), and if it is not completed (Step 4
Return to -3). From then on, the microcomputer 13 will proceed from (Step 4-3) → (Step 4-11) → unless cleaning is completed.
(Step4-12) → (Step4-13) → (Step4-14)
→ (Step4−15) → (Step4−16) → (Step4−
17) → (Step4−18) → (Step4−10) → (Step4
The microcomputer 13 performs control so that the control sequence of -3) is repeated, so that once the setting means is operated, the temperature of the cleaning water at the set value is obtained from then on. When cleaning is completed, the pump is de-energized and the heater is de-energized.
(Step 4-19), the means for terminating the cleaning is the same as that described in the general flow of conventional control, and will therefore be omitted.

Effects 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. Further, if the user is satisfied with the 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 user can immediately obtain the desired washing water temperature, so it is versatile enough that all people can use it comfortably regardless of the user's local condition. .
