Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sanitary cleaning device for cleaning private parts of the human body with warm water.

Conventional configuration and its problems The general configuration of a sanitary cleaning device is shown in FIGS. 1 and 2.

1 is a toilet bowl, 2 is a toilet that stores water for flushing the inside of the toilet bowl 1, 3 is a toilet seat installed on the toilet bowl 1, 4 is a lid, 5
1 is a sanitary cleaning device body located behind the toilet seat 3 and installed on the toilet bowl 1; 6 is a nozzle body that discharges cleansing water to the private parts of a person sitting on the toilet seat 3; and 7 is a cistern 2. 8 is a tank for storing cleaning water; 9 is a heater for heating the cleaning water in tank 8; 10
11 is a sensor that monitors the temperature of the cleaning water, and 11 is a sensor that monitors the temperature of the cleaning water.
A pump that suctions the water inside through a hose 7 and pumps it into a tank 8, and at the same time pumps water at an appropriate temperature inside the tank 8 through a hose 12 to the nozzle body 6. 13 is an operation knob, and 14 is a signal from a sensor 1°. This is a controller that controls the heater 9, pump 11, etc. according to the operation knob 13. The cleaning water in the tank 8 is always kept at an appropriate temperature (approximately 40'C) by a sensor 9, a control circuit 14, and a heater 9, and when cleaning is performed, the operation knob 13 is operated to energize the pump 11. , water pressure is applied to the nozzle body 6, the nozzle body extends to the lower part of the human body private part, and cleaning water is discharged.

In most conventional sanitary washing devices, when washing is performed in cold weather, cold water is released at the beginning of the washing process, causing an unpleasant feeling.

The reason for this is that the residual cold water in the hose 12 and nozzle body 6 is discharged toward the human body. Since the washing water is completely cold, it is cooled while passing through the corridor, and there is a problem in that the cold water is inevitably discharged at the beginning of the washroom. As a solution to the above-mentioned drawbacks, a configuration has been considered in which the amount of energization of the pump is reduced for a certain period of time during the initial stage of cleaning, and the cleaning water is discharged with such force that the cleaning water does not reach the human body, thereby eliminating the cold water. The problem is that it takes a long time to remove the water and that there is a lot of waste because the removal operation is performed even when the toilet is not cold. A configuration in which water leaks into the water was also considered, but in either case, the temperature of the washing water itself could not be monitored, so the performance was insufficient and there was a lot of wasted hot water.

OBJECTS OF THE INVENTION The present invention solves such conventional problems and aims to eliminate cold water reliably in a short time.

Structure of the Invention In order to achieve this object, the present invention provides a shape memory device which is provided in a nozzle body so as to be in contact with the cleaning water, and which switches the direction of cleaning water discharge depending on whether the cleaning water is cold water or hot water. It is equipped with an alloy driving body.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. 15 is a nozzle case, 16 is a movable nozzle, 17
18 is an opening provided at the tip of the nozzle case 15 to allow the movable nozzle 16 to protrude; 19 is an opening provided at the tip of the movable nozzle 16; The spring 20 biasing the movable nozzle 16 in the housing direction fully extends when the temperature is lower than 36° C., so that the movable nozzle 16 is stored in the nozzle case 15 regardless of whether water pressure is applied or not. A spring-like shape memory alloy driver that contracts when the temperature rises above 36°C; 21 is an O-ring that ensures watertightness between the movable nozzle 16 when it protrudes from the nozzle case 15; and 22 is cleaning water that is discharged.

In the configuration described above, when the nozzle body 6 is not being cleaned and the nozzle body 6 is cold, the shape memory alloy driving body 20 is extended and cut into 5 squares, so that it is in the state shown in FIG. 3. When cleaning is started at this time, the state shown in Fig. 3 is maintained as long as the cleaning water is colder than 36°C, and the cleaning water that comes out of the jet hole 17 diffuses into the nozzle case 15 and then flows through the opening 18 of the nozzle case. It flows down towards the toilet bowl.

The cleaning water becomes hot and the shape memory alloy driving body 20 reaches 36°C.
As the height increases, the movable nozzle 16 contracts due to water pressure.
protrudes from the opening 18 and is in the state shown in FIG.
The cleaning water 22 is vigorously jetted from the spout hole 17 toward the human body. Therefore, the temperature of the washing water at this time is 36° C. or higher, which ensures that washing can be carried out in a warm station. When the pump is deenergized after cleaning, water pressure is no longer applied, so the movable nozzle 16 is moved to the nozzle case 15 by the action of the spring 19.
stored inside. At this time, the shape memory alloy drive body 20 remains shrunk, but there is a time until the next cleaning, and when the nozzle body 6 cools and the temperature drops below 36°C again, the shape memory alloy drive body 20 expands, as shown in FIG. Return to state. If it is not long until the next cleaning and the nozzle body 6 has not yet cooled down, the remaining water is still warm and there is no need to discard the water, then the shape memory alloy drive body 2
Since water pressure is applied in the state where 0 is contracted, the washing water is immediately discharged to the human body in the state shown in Fig. 4, and no wasteful water discharging operation is performed.

Next, another embodiment of the present invention will be described using FIGS. 5 to 7. 23 is a rectangular nozzle tube, 24 is an ejection hole provided at the tip of the rectangular nozzle tube and opened toward the human body, 25 is a drain port similarly opened toward the toilet bowl, and 26 is itself 36
If the temperature is lower than 36°C, turn in the direction shown in Figure 5 to create a cleaning channel on the side of the waste water outlet 25, and if higher than 36°C, turn in the direction shown in Figure 7 to create a cleaning channel at the spout hole. This is a tongue-shaped shape memory alloy drive body made on the 24 side.

In the second configuration, when the nozzle body 6 is not being cleaned and the nozzle body 6 is cold, the shape memory alloy driving body 26 is in the state shown in FIG. If you start cleaning at this time, the cleaning water will reach 36°C.
While it is colder, the condition shown in Figure 5 is maintained, and the washing water is drained from drain port 2.
5 is discharged toward the toilet bowl. When the temperature of the cleaning water becomes higher than 36°C, the shape memory alloy driving body 26 begins to bend in the opposite direction 7, , as shown in FIG. It switches gradually, and finally switches completely as shown in FIG. Therefore, the temperature of the washing water at this time is 36°C or higher.
-, it is possible to reliably wash with warm water, and as the shape memory alloy driving body 26 moves, the washing water discharge from the jet hole 24 gradually becomes stronger, so that the washing starts feeling soft.

Effects of the Invention As described above, the nozzle body of the sanitary washing device of the present invention is provided with a shape memory alloy driving body that is provided so as to be in contact with the washing water and switches the washing water discharge direction depending on whether the washing water is cold water or hot water. When the shape memory alloy is cold, the wash water is released toward the toilet bowl, and when it is warm, it is released toward the human body, so cold water is released into the human body at the beginning of cleaning, causing discomfort to the user. Moreover, the flushing water is only discharged into the toilet bowl when it is cold, and is immediately discharged toward the human body when it is warm, so there is no wastage of hot water or wasted time, and furthermore, flushing water is discharged quickly. Since the temperature of the cleaning water in the nozzle body is detected and the direction of discharge of the cleaning water is switched, cold water is reliably removed.
