Abstract

PROBLEM TO BE SOLVED: To provide a hot water bidet to be mounted in a place where there is no hot-water supply source nor power source. SOLUTION: This hot water bidet S has main mechanical parts built in a toilet seat box R, to which a thermal tank T for saving hot water is detachably attached. Hot water in the thermal tank T and water from a water pipe are mixed at a mixing valve to get hot water of an appropriate temperature, and the hot water of an appropriate temperature is jetted out of a washing nozzle for washing with hot water. As high-temperature hot water can be saved in the thermal tank T, hot water of a required temperature can be supplied for a longer time. And as the thermal tank T has the same vacuum double-wall structure as that of a thermos bottle, washing with hot water can be executed after a long time has passed. In addition, as high-temperature hot water is saved, washing with hot water can be executed for a longer time, so a thermal tank with a smaller capacity can be adopted.

The toilet seat box R is provided with an insertion portion 1 for a heat retaining tank T for storing hot water, and the heat retaining tank T is configured to be detachable from the toilet seat box R.

As shown in FIG. 2, the heat retaining tank T has a vacuum double wall structure in which a vacuum portion is sandwiched between an inner wall 2 and an outer wall 3 like a thermos bottle. A hot water inlet 10 is provided. A carrying handle 12 as shown may be provided. A hot water discharge unit 4 is formed at the bottom, and a discharge port 5 of the discharge unit 4 is formed.
For example, a ball valve 6 is disposed, and when hot water is stored in the heat retaining tank T, the discharge port 5 at the bottom is closed by the ball valve 6 by water pressure. On the other hand, the tank insertion portion 1 of the toilet seat box R is provided with a receiving portion 7 that fits with the discharge portion 4 of the heat retaining tank T, and a rod 8 is provided upright at the center of the receiving portion 7. I have. The rod 8 is inserted into the discharge port 5 to push up the ball valve 6 when the heat retaining tank T is inserted. Therefore, when the heat retaining tank T is inserted into the insertion portion 1 of the toilet seat box R and the bottom discharge portion 4 is fitted to the receiving portion 7, the rod 8
Opens the discharge port 5, so that the hot water can flow out.

As shown in FIG. 3, the main components of the hot water cleaning apparatus S of this embodiment include a heat retaining tank T, a pump, a mixing valve, an on-off valve such as a solenoid valve, a cleaning nozzle, a battery, a controller, and the like. ing. Although not shown, the cleaning nozzle may be provided with a pressure regulating valve, or the pressure regulating valve may be disposed immediately upstream of the cleaning nozzle. Hot water that can flow out by inserting the heat retaining tank T into the toilet seat box R is sent to a mixing valve by a pump, and mixed with water supplied from a water supply pipe at the mixing valve to obtain appropriate-temperature hot water. After that, it is sent to the cleaning nozzle. An on-off valve such as a solenoid valve is provided between the mixing valve and the cleaning nozzle, and by opening this,
Hot water is ejected from the washing nozzle by the pressure of the hot water supply pressure of the pump and the water supply pressure of the water supply pipe. In the present invention, a battery is used as an operating power supply for electric components such as a pump and an electromagnetic valve, and the operations of the pump and the electromagnetic valve are controlled through a controller. A rechargeable storage battery may be used as the battery, or a solar cell may be used if sunlight can be collected.

The hot water washing apparatus S of the present invention constructed as described above operates the controller to open the solenoid valve and drive the pump, so that the hot water in the heat retaining tank T and the water in the water supply pipe are mixed by the mixing valve. Warm water of an appropriate temperature obtained by mixing is jetted from a washing nozzle to wash the body of the user. The hot water washing can be continued until the hot water in the heat retaining tank T runs out, so that storing hot water in the heat retaining tank T makes it possible to extend the time for obtaining hot water at a desired temperature. Since the heat retaining tank T has the same vacuum double-wall structure as the thermos, it is possible to keep the internal hot water for a long time, so that after pouring into the heat retaining tank T, it is washed with hot water even after a long time has passed. It is possible to perform When the hot water runs out, hot water (preferably hot water immediately after boiling) is replenished from the inlet 10 and the inside of the heat retaining tank T is filled with hot water. Although the capacity of the heat retaining tank T is not particularly limited, it is not preferable to set the capacity to be too large in consideration of carrying around for refilling hot water. In addition, if high-temperature hot water is stored, washing with hot water for a long time is possible.

The embodiments of the present invention are not limited to the above. For example, the heat retaining tank T may have a structure fixed to the toilet seat box R as long as it has an inlet for refilling hot water. As described above, the present invention does not prevent the present invention from being appropriately changed in accordance with the state of implementation.
