Description

[Detailed Description of the Invention] This invention relates to a hot water irrigator used, for example, when a person suffering from hemorrhoids cleanses the anal region.

The cleaning nozzle of the hot water washer described above needs to be sterilized and disinfected in order to clean the affected area, and conventionally, the nozzle has been cleaned with a liquid specifically designed for sterilization.

When performing sterilization and disinfection in this manner, it is necessary to prepare liquids, containers, cleaning tools, etc. for sterilization, which is very troublesome.

Therefore, the purpose of this invention is to provide a hot water washer that can easily sterilize the cleaning nozzle.

According to this invention, since a sterilizing nozzle that heats the cleaning water to a high temperature and spouts out the high-temperature water is provided, the cleaning nozzle can be easily sterilized using this high-temperature water.

This eliminates the need for special preparations such as disinfectants and disinfectant tools, allowing for clean and hygienic cleaning.

An embodiment of this invention having such characteristics will be described in detail below based on the drawings.

The drawing shows a hot water washer, and in FIG. 1, 1 is a tank that stores cleaning water.

A pump 2 is driven by a motor 3 and pumps out cleaning water from the tank 1.

4 is a heater, which has a secondary heating line 5 and a secondary heating line 6, uses a sheathed heater 7 as a heating source, and connects the primary heating line from the pump 2 with a connecting pipe 8. Connected to 5.

Reference numeral 9 denotes a flow divider valve that divides the hot cleaning water supplied from the primary heating line 5 of the heater 4 into three directions, one of which is a cleaning nozzle to be described later, and one which is used for the secondary heating of the heater 4 described above. line 6, and the other end is connected to tank 1 via connecting pipe 10 to return to tank 1.

Reference numeral 11 denotes a hand holder, which has a cleaning nozzle 12 and an on-off valve 13, and is connected to the aforementioned diversion valve 9 through a flexible pipe 14. During cleaning, the hand holder 11
is held, the water supply passage is opened with the on-off valve 13, and the cleaning area is cleaned with the cleaning warm water jetted from the cleaning nozzle 12.

Note that the above-mentioned on-off valve 13 is configured to turn off the power of the motor 3,
The switches that are turned on are connected in a linked manner.

An on-off valve 1 is provided at the other end of the secondary heating line 6 of the heater 4 described above.
5 is connected via a connecting pipe 16, and a sterilization nozzle 17 is connected to this on-off valve 15. Normally, the valve 15 is closed, and when the cleaning nozzle 12 is sterilized, the sterilization is performed by opening the valve 15. High-temperature water is ejected from the nozzle 17, which can perform sterilization.

The aforementioned heater 4 controls the sheathed heater 7 so that the cleaning water in the tank 1 can be kept at about 25°C, and when the cleaning is used, the primary heating line 5 is connected to the cleaning hot water jetted from the cleaning nozzle 12 to keep the cleaning water at about 25°C. The sheathed heater 7 is controlled so that the temperature is 40°C, and by passing the cleaning hot water from the secondary heating line 5 to the secondary heating line 6 via the diverter valve 9, the sterilization nozzle 17 outputs a temperature of 90 to 95°C. It is set so that high temperature water can be taken out.

In the figure, 18 is a small pressure release hole provided in the secondary heating line 6, and 19 is a thermostat that detects the temperature of the warm water in the tank 1 and sets the temperature, for example, 2.
It operates with the detection line set at 5°C.

FIG. 2 shows the above-mentioned heater 4. This heater 4 has three through holes 21, 22, and 23, upper and lower, bored in the longitudinal direction of the heating body 20 made of a rectangular aluminum material. Through hole 21.
A cap 24 is attached to each end of the 23 to form the above-mentioned primary heating line 5 and secondary heating line 6, and the through hole 22 is fitted with the above-mentioned sheathed heater 7. .

In addition, when installing this heater 4 in the tank 1, since both end surfaces of the heating body 20 are formed in a flat shape, an appropriate seal is interposed between this and the inner wall surface of the tank 1. By attaching the cap 24 from the outer wall side of the tank 1,
Leakage of cleaning water can be prevented.

FIG. 3 shows a control circuit for the motor 3 and the sheathed heater 7. The motor 3 is driven by a motor drive control circuit 26 when a switch 25 interlocking with the on-off valve 13 provided on the hand holder 11 is turned on. Ru.

The signal from the switch 25 described above is also input to the current control circuit 27, and the signal from the thermostat 19 described above is also input to this current control circuit 27.

The above-described current control circuit 27 controls the current supplied to the sheathed heater 7 to control the heating of the sheathed heater 7 during heat retention and during cleaning.

For example, this circuit 27 is composed of a triac, and when a signal is input from the thermostat 19, a half wave of AC power is supplied to the sheathed heater 7 for heating during heat retention, and a switch 25 interlocked with the on-off valve 13 is activated. When it is turned on and the signal is input, it supplies full-wave AC power to perform heating during cleaning.

As a result, the wash water in tank 1 is normally supplied to thermostat 1.
9, it is kept warm at a temperature of 25°C, for example, and when using the washer, hot water for washing can be obtained at 40°C.

In the hot water washer configured as described above, the wash water in the tank 1 is normally kept at about 25° C. by the heater 4.

When using this, the user holds the hand holder 11 and operates the on-off valve 13 to open.

This operation turns on the switch 25, drives the motor 3, and the pump 2 supplies the cleaning water in the tank 1 to the heater 4.

At the same time, a full wave of AC power is supplied to the sheathed heater 7, which heats the cleaning water flowing through the secondary heating line 5.
Cleaning hot water of 40° C. can be spouted from the cleaning nozzle 12, and the cleaning area is cleaned with this.

Further, when the cleaning nozzle 12 is to be sterilized, the on-off valve 15 is opened and high temperature water is jetted from the sterilization nozzle 17, thereby sterilizing the cleaning nozzle 12.

Although a small hole 18 is formed in the secondary heating line 6, since it is a small hole, there is no problem in ejecting high-temperature water.

Also, even when the sterilization nozzle 17 is not in use, the secondary heating line 6
The hot washing water inside is heated, but when this line 6 reaches a high temperature, pressure is released into the tank 1 through the small hole 18 mentioned above.

In addition, the high pressure in line 6 is also discharged to the diverter valve 9 side, and the connecting pipe 1
0 into the tank 1, the small hole 18 described above is not necessarily necessary and can be omitted.

Furthermore, when the washer is in use as described above, a portion of the hot cleaning water is returned from the diverter valve 9 into the tank 1 via the connecting pipe 10, so that the cleaning water in the tank 1 is made to flow. This flow prevents the wash water from spoiling and from cultivating germs.

In the above-mentioned embodiment, the heater 4 is provided inside the tank 1 to keep and heat the cleaning water in the tank 1, but this heater 4 is provided outside the tank 1, and the heater 4 is provided outside the tank 1.
It is also a good idea not to heat the cleaning water inside.

Furthermore, the high-temperature water spouted from the sterilization nozzle 17 is obtained by heating the hot water in the primary heating line 5 and passing it through the secondary heating line 6, but the secondary heating line 6 is lengthened and the cleaning hot water is supplied to the cleaning nozzle 12. Separately, a heating line for high-temperature water for sterilization may be provided.

In this case, the heating body 20 is used to increase the secondary heating line 6.
It is preferable that one additional through hole be connected to the heater 4 and the flow dividing valve 9 be provided at the front stage of the heater 4.

Further, the above-mentioned high-temperature water may be configured to be configured to switch between the sterilizing nozzle 17 and the return line to the tank 1 using a switching valve, so that the high-temperature water is returned to the tank 1 when not in use.

Further, the current of the heater 7 may be controlled by detecting the temperature change in the tank 1 using a thermistor and inputting this to the current control circuit 27 to control the heater 7, or by directly turning off the power to the heater 7 using a thermostat.

It may also be controlled to be ON.

Furthermore, although the heater 4 uses a sheathed heater 7 as its heat source,
Other heat sources may also be used.

FIG. 4 shows another example of the heater 4 described above, and this heating means uses heat generated by the electrical resistance of the secondary winding of the transformer.

This transformer 28 consists of an iron core 29, a negative winding 30, and a secondary winding 31, and both ends of the secondary winding 31 are connected to short-circuit wires 3.
2 is short-circuited.

The above-mentioned secondary winding 31 can be wound several times less than the primary winding 30, and the conductor is formed of a hollow pipe with a large electric capacity, with the inside serving as a water supply passage. One end is used as a water supply port from the pump 2 side, the middle part is used as an outlet for cleaning warm water via a flow dividing valve 33, and the other end is used as an outlet for sterilizing high temperature water.

The heater configured in this way has the primary winding 3 of the transformer 28.
If AC power is supplied to the 0 side, the shorted secondary winding 31
A large current momentarily flows through the secondary winding 31, which turns into heat due to the electrical resistance of the secondary winding 31, heating the cleaning water flowing through the internal water supply passage of the secondary winding 31, and converting it into hot water and high-temperature water. can do.

The heater may be configured in this way. Note that the drive and heating of the motor and sheathed heater were controlled by turning on the switch 25 during cleaning.
Another method is to provide a motor drive switch that is turned ON to drive the motor when cleaning is used, and to direct the flow of hot cleaning water to the terminal of the primary heating line 5 of the heater 4 (the position before entering the flow divider 9). It is also possible to provide a flow rate switch that turns on when detecting the flow and turns off when no flow is detected, and to control the heating of the sheathed heater 7 using a signal from the flow rate switch.

In this case, the switch 25 that interlocks with the on-off valve 13 of the hand holder 11 can be omitted, and even if the above-mentioned on-off valve 13 is opened, as long as the above-mentioned flow rate switch does not detect the flow of hot cleaning water, the switch 25 can be omitted. Since heating of the heater 4 is not controlled, dry heating can be prevented.
