Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sanitary cleaning device having at least cleaning, drying, and flushing functions.

Structure of conventional example and its problems As shown in FIGS. 1 and 2, this type of sanitary cleaning device has a toilet seat 3 and a device body 4 installed on top of a toilet bowl 2 having a cistern 1, and private parts cleaning means. a nozzle 5 that discharges cleansing water to the private parts of a human body sitting on a toilet seat 3; a water filter 6 submerged in water in the cistern 1; and a nozzle 5 from the water filter 6.
It has a pump 7 and a cleaning switch 8 for pumping cleaning water, a hot air outlet 9 and a fan 10 as drying means for drying the private parts, a motor 11 for rotating the fan, and a heater 12 for heating the air blown from the fan.
and a drying switch 13, and the water washing means includes a water valve 14, a chain 15 connected to the water valve, and by rotating the chain 15 by a certain angle, the chain 15 is pulled up to close the valve 1.
It has an arm 16 that opens the toilet seat 4 and a rotary solenoid 17 that rotates the arm 16 to a certain angle. The hinge 18 is rotatably connected and can be moved slightly in the vertical direction.When no human body is sitting on the toilet seat 3, the hinge 18 is lifted upward and turned off. It has a seat detection switch (micro switch) 19 that turns on the hinge 18 when it is lowered, and receives signals from the cleaning switch 8, drying switch 13, and seat detection switch 19 as input to drive the pump 7, motor 11, heater 12, and rotary solenoid. It has biasing means 20 for biasing 17. The urging means 20 is mainly operated by a microcomputer.

In the sanitary cleaning device described above, a schematic flow diagram of the conventional urging means 20 is shown in FIG.
At steps 2 and 23, it is remembered that the human body has sat on the toilet seat 3, and at steps 24 to 27, washing is performed for a certain period of time using a cleaning switch, and at steps 28 to 31, drying is performed for a certain period of time using a drying switch.
The system detects that the human body has stood up from the toilet seat 3 at step 4, flushes the toilet at steps 35 and 36, and returns to the start. At this time, the delay time W seconds indicated by 33 is to prevent the seat detection switch 19 from being turned off when the human body floats on the toilet seat 3 for a short period of time, thereby preventing erroneous flushing. Even if the seat detection switch 19 is turned off, if it is turned on within W seconds, it will not be considered as a stand-up. However, a problem unique to sanitary washing devices is that even if you leave the water adhering to the washing water after washing and dry it, it takes a long time (more than 5 minutes) to finish drying, so most users do not use the toilet after washing. Drying is performed after removing water droplets with paper, reducing drying time. Many people float their bodies when removing these water droplets, but the time it takes to float is more than 10 seconds, so the delay time W seconds is set to about 20 seconds to prevent the water washing means from being energized by mistake during that time. must be set to a long value. However, although this eliminates malfunctions, the flushing does not occur immediately after the toilet seat is finished drying, leaving the user wondering if the toilet will actually flush or not. A problem has occurred that makes me feel anxious that my machine may be malfunctioning.

Purpose of the invention The present invention solves such conventional problems,
The purpose of the present invention is to provide a sanitary washing device which reduces the number of erroneous washings and also allows the washing to be carried out quickly when the device is started up after drying.

Structure of the Invention In order to achieve this object, the present invention provides first and second delay times, and detects the rise of the human body after energizing the water washing means or after energizing the drying means. In this case, an energizing means is provided for energizing the flushing means after a second delay time shorter than the first delay time.

DESCRIPTION OF EMBODIMENTS A schematic flow diagram of the biasing means of the present invention is shown in
As shown in the figure, the difference from Figure 3 is that 37 is used to remember whether or not drying was performed between sitting on the toilet seat and standing up. If drying is performed, the washing means is energized through step 39, which constitutes a first delay time, and if drying is performed, through step 40, which constitutes a second delay time. X seconds as the first delay time is set to, for example, about 20 seconds, and Y seconds as the second delay time is set to a value of about 3 seconds, for example. Note that 41 is for canceling the memory of dryness.

In the above configuration, even if you lift your body off the toilet seat and use toilet paper to remove water droplets after washing, the time it takes for your body to float is the first delay time (X
= 20 seconds), the flushing means will not be energized and the flushing completed state will be maintained by sitting on the toilet seat again. After that, the drying means is energized, but there is no need to keep the body floating for a long time during drying, and even if it is hot, it will be in a floating state for a short time by moving the body, and in that case, the second delay time (Y=3
(seconds) to prevent accidental washing. When the user stands up from the toilet seat after drying, the flushing is immediately performed after the second delay time, that is, after 3 seconds. Also, people who do not use flushing or drying methods at all, or who are busy and after flushing and removing water droplets with toilet paper, get up from the toilet seat and leave without drying. Even in this case, the water washing means is reliably energized after the first delay time, so there is no need to worry about odor being emitted for a long period of time without being washed.

Effects of the Invention As described above, the sanitary cleaning device of the present invention detects the rising of a human body in response to a signal from the seat detection means, and
The rinsing means is energized after the first delay time, or if the rising of the human body is detected after the drying means is energized, the rinsing means is energized after a second delay time shorter than the first delay time. This means that after washing, if you need to float for a long time and remove water droplets with toilet paper, use the first method.
The second delay time works to prevent accidental flushing, and when the user stands up from the toilet seat after drying, which is the final step in general usage, the second delay time allows the toilet to be flushed immediately. Therefore, it has the feature that the flushing operation is performed accurately and that the flushing is performed quickly when the user stands up from the toilet seat.
