[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hot water tank of a hot water flush toilet, and more particularly to a hot water tank for jetting hot water from a washing nozzle to perform local washing.

[0002]

[Prior art and problems]

 The hot water flush toilet is a tank that supplies water to the toilet bowl and the toilet bowl, and a cleaning nozzle that extends into the toilet bowl after defecation and discharges hot water toward the user's local area, and preheats the hot water to supply hot water to the cleaning nozzle. It consists of a hot water tank. Unlike the water in the main tank, the conventional hot water in the hot water tank takes a long time to heat up, so it does not release all of it in one use, and it seems that there is still room for the next use immediately. In addition, hot water for several times is always held. Therefore, the water in the hot water tank has been heated for a long time. The temperature is approximately 35 to 40 ° C., but this temperature range is the temperature zone where pathogenic bacteria and miscellaneous bacteria are most likely to propagate.

The water introduced to the hot water tank is usually tap water, which is usually sterilized, but it is often the case that excrement adheres to the cleaning nozzle and flows back to contaminate the inside of the hot water tank. In addition, bacteria in the air may invade from the nozzle opening and go back up the water circuit to reach the hot water tank, and may be contaminated by bacteria in the air in the hot water tank. In this way, it is inevitable that various bacteria will be mixed in after long-term use. Once pathogenic bacteria and miscellaneous bacteria have propagated in the hot water tank, hot water containing them will be sprayed on the anus, and there is a risk that local areas that would otherwise have to be sterilized and washed will be contaminated with pathogenic bacteria. In addition, a bad odor may be emitted due to the deterioration of the tank. Furthermore, if it is not used for a long time, water moss will be generated in the warm water tank due to the growth of various bacteria, which not only takes time to clean it, but also often clogging the water circuit and washing nozzle, making it impossible to discharge hot water.

[0004]

【Purpose】

 The present invention has been made in view of the above points, and there is no possibility that pathogens and miscellaneous bacteria will propagate in the hot water tank for hot water and hot water will become a source of infection of diseases, and the cleaning nozzle will not be clogged. It is intended to provide a hot water tank.

[Means for solving problems]

 The gist of the present invention is to provide a toilet bowl, a tank for supplying water to the toilet bowl, a cleaning nozzle that extends into the toilet bowl after defecation, and discharges the warm water toward the user's local area, and preheats the warm water to warm the cleaning nozzle. In a hot water washing toilet bowl consisting of a hot water tank that supplies water, the hot water tank is divided into a plurality of chambers each having a heating means, and this heating means has a circuit that constantly warms water to a proper washing temperature and a regular time. It is characterized by being provided with a circuit for heating to an appropriate temperature for sterilization and having a selection means for supplying water to the cleaning nozzle only from a chamber in which the water has an appropriate temperature for cleaning.

The present invention is first applied to an ordinary hot water flush toilet bowl. Washing with hot water The toilet bowl is a toilet bowl, a tank that supplies water to the toilet bowl, and a cleaning nozzle that extends into the toilet bowl after defecation and discharges hot water toward the user's local area It consists of a tank. The hot water tank is divided into a plurality of chambers each having a heating means, preferably two chambers, and the heating means is a heating circuit for heating the water to a temperature suitable for cleaning by discharging it locally to the user. A heating circuit is provided to heat to a temperature suitable for sterilizing pathogens and germs.

The sterilization suitability temperature is a temperature suitable for sterilizing pathogenic bacteria and miscellaneous bacteria, and is generally about 80 ° C., but it may be slightly lower or higher. Further, the driving of the circuit for heating to the sterilization proper temperature is performed on a regular basis. The term “scheduled” means that the heating means automatically operates at a fixed time such as once or several times a day, once every two to three days. It is possible to set each circuit that regularly heats to an appropriate temperature for sterilization so as to be turned on separately in different time zones for each room, but a circuit that is selectively turned on may be provided separately. Further, the present invention is provided with a selection means for supplying the water discharged from the cleaning nozzle from the chamber in which the water has become the proper temperature for cleaning, whereby only the hot water is supplied from the cleaning nozzle. This selection means may be either electrical means or mechanical means, but each room is equipped with a temperature sensor, and a water circuit to the cleaning nozzle is opened at the appropriate temperature for cleaning via a valve, and otherwise. The one that closes the water circuit.

[0008]

[Action]

 Since the present invention is configured as described above, the water in the hot water tank is always heated to the proper cleaning temperature, but the circuit for heating to the proper sterilization temperature ensures that the water in any room is It is heated to a proper sterilization temperature such as 80 ° C., which is sequentially performed for each room to sterilize the water in each room. As long as the heated water does not fall to the proper cleaning temperature, the water in that chamber does not flow into the water circuit to the cleaning nozzle, and hot water is supplied only from the chamber that has the proper cleaning temperature.

[0009]

【Example】

 Referring to the drawings, 1 is a hot water tank attached to a hot water flush toilet, and this hot water tank 1 is divided into two chambers 2 by a partition wall 3 and water is supplied from a water supply source 4. . Each chamber 2 is connected to a cleaning nozzle 6 via a water channel 5. Although not shown, the cleaning nozzle 6 is attached to the toilet bowl and extends into the toilet bowl after defecation. A valve 7 is provided in the water passage 5 from each room. This valve 7 measures the temperature of water in each room by a temperature sensor 8 provided in each room 2, It is a selection means that opens and closes so that only the water channel 5 communicates. Each chamber 2 is provided with a heater 9 as a heating means, and each heater 9 is connected in parallel to a heating circuit 10 for heating to an appropriate temperature for cleaning and a heating circuit 11 for heating to an appropriate temperature for sterilization. Each heating circuit 11 is connected to the switching circuit 12. 13 is a power supply.

[0010]

【effect】

 Since the present invention is configured as described above, the water in the hot water tank is constantly warmed and heated to the appropriate temperature for sterilization on a regular basis, so that pathogenic bacteria and miscellaneous bacteria that enter the hot water tank are As a result, the water in the hot water tank is sterilized and the clean state is always maintained. In addition, since the water in the hot water tank is constantly heated to the appropriate temperature for cleaning, heating it to the appropriate temperature for sterilization on a regular basis does not require much electric power, but can efficiently perform sterilization. . Further, since the heating means for heating can be shared, the manufacturing cost can be reduced.
