Description

[Detailed explanation of the idea] 【Technical field】

TECHNICAL FIELD The present invention relates to a hot water purifying device for washing private parts with warm water after using the toilet.

[Background technology]

Conventional hot water cleaning devices have a hot water tank equipped with a heater inside the cleaning device itself, which is installed above the toilet bowl, and a pump pumps up the tap water in the low tank and sends it to the hot water tank. The water was heated inside the tank and the hot water was discharged from the injection nozzle using the pressure of the pump. Therefore, in order to install a hot water washing device, it is necessary to install the hot water washing device, which is equipped with many devices such as a heater, a hot water tank, and a pump, above the toilet bowl, resulting in high equipment costs. In addition, a hot water tank for the hot water cleaning device is required in addition to a heat source device such as a hot water storage tank for supplying hot water to bathtubs and sink faucets, which has the disadvantage of wasting equipment and increasing running costs. As shown in Japanese Utility Model Application No. 60-154472, it has also been proposed to use an external heat source, but in this case, the heat that has cooled down in the pipes leading to the cleaning equipment The problem is that water is discharged.

[Purpose of invention]

The present invention was developed in view of the technical background described above, and its purpose is to use existing equipment or to share equipment with other equipment. To provide a hot water washing device capable of reducing cost and running cost and surely spouting water at an appropriate temperature.

[Disclosure of invention]

The hot water cleaning device of the present invention is equipped with a cold water removal device that removes low-temperature hot water by having a heat-sensitive member and a valve operated by the heat-sensitive member. The machine is connected to a mixing thermovalve, the water pipe is connected to the mixing thermovalve, and an injection nozzle for hot water injection is connected to the mixing thermovalve that mixes hot water and tap water into water at an appropriate temperature. This is a characteristic feature. However, heat source equipment such as hot water tanks that supply hot water to bathtubs and kitchens 1
By using this, the existing heat source device 1 can be used or the heat source device 1 can be shared, and a hot water cleaning device can be constructed at low cost without installing a conventional expensive hot water cleaning device. Furthermore, by utilizing the water pressure or water pressure of the heat source device 1, the pump can also be omitted. Further, since it is equipped with a cold water removal device 3, it is possible to prevent cold water from being unexpectedly discharged from the injection nozzle 5, and because it is equipped with a mixing thermo valve 4, hot water at a constant temperature can be prevented from being discharged from the injection nozzle 5.
Moreover, since the cold water removing device 3 is provided before mixing the hot water and tap water, the cold water can be removed more quickly than when the cold water is removed after mixing. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The heat source device 1 is like a hot water storage tank for supplying hot water to bathtubs, kitchens, etc., and a hot water outlet of the heat source device 1 is connected to a cold water removal device 3 via a hot water pipe 6 via a starter valve 7. Further, the water pipe 2 is branched, and one side supplies water to the heat source device 1, and the other side is connected to the cold water removal device 3. This cold water removing device 3 is designed to drain low temperature hot water to a drain 8. Furthermore, the hot water and tap water are separately supplied from the cold water removal device 3 to the mixing thermovalve 4, and the mixing thermovalve 4 changes the mixing ratio of the hot water and tap water according to their temperatures. , produces mixed water at a constant set temperature. A mixed water outlet of the mixing thermovalve 4 is connected to an injection nozzle 5 installed in the toilet bowl 9. The structure of the cold water removal device 3 is shown in FIG. A partition plate 1 is provided inside the cold water flow path 13 that connects the cold water inlet 11 and the cold water outlet 12 provided in the upper part of the casing 10.
4, and the valve seat hole 15 of the partition plate 14 is opened and closed by an upper valve 16. A hot water flow path 19 connecting a hot water inlet 17 and a hot water outlet 18 provided at the lower part of the casing 10 is also partitioned by a partition plate 20.
An inlet valve seat hole 21 opened between the cylindrical slide valve 22 and the casing 10 is opened and closed by the circumferential surface of a cylindrical slide valve 22, and an outlet valve seat hole 2 opened in the partition plate 20
3 is opened and closed by a lower valve 24. Furthermore, the inlet valve seat hole 2 at the back of the hot water inlet 17
A drain 8 is opened near the lower side of the drain 1, and the inlet valve seat hole 21 and the drain 8 are alternately opened and closed by the movement of the slide valve 22. Further, a spring 25 made of a normal material is inserted under the water side of the slide valve 22, and urges the slide valve 22 toward the entrance toilet seat hole 21 side, thereby causing the slide valve 22 to close the entrance valve seat hole 21. A heat-sensitive spring 26 made of a shape memory alloy is inserted on the water side of the slide valve 22. The heat-sensitive spring 26 made of this shape memory alloy has a transformation temperature that is approximately equal to the comfortable hot water temperature, and below the transformation temperature, the slide valve 22
It contracts to retreat into the inlet valve seat hole 21, but when the water temperature reaches a comfortable temperature, it expands beyond the transformation temperature, becomes a spring with a spring constant larger than that of the spring 25, and resists the elastic force of the spring 25. Then, the slide valve 22 is moved toward the drain 8 side, and the drain 8 is closed by the slide valve 22. In addition, a diaphragm valve 27 with one side facing inside the hot water flow path 19 and the other side facing the atmosphere is provided for the air between the inlet valve seat hole 21 and the outlet valve seat hole 23 in the hot water flow path 19. The diaphragm valve 27 is formed integrally with a shaft 28 that vertically and slidably passes through the casing 10, and the upper and lower valves 16 and 24 are attached to the upper and lower ends of the shaft 28, respectively. The shaft 28 is connected to the upper and lower valves 16 by a spring 29.
24 in the closing direction. When the starting valve 7 is opened, the hot water in the heat source device 1 flows into the hot water inlet 17 of the hot water flow path 19.
Immediately after the start valve 7 is opened, the cold water accumulated in the hot water pipe 6 is supplied to the hot water inlet 17. While this cold water is being supplied to the hot water inlet 17, the heat-sensitive spring 26 is compressed to open the drain 8, and the cold water is discharged from the drain 8 through the hole 30 in the center of the slide valve 22. When all the cold water is removed and hot water is supplied, the thermal spring 26 is expanded to close the drain 8 and the inlet valve seat hole 21. When the inlet valve seat hole 21 is opened, hot water flows into the diaphragm valve 27, pushes the diaphragm valve 27, slides the shaft 28 downward, and opens the upper and lower valves 16,
24 at the same time. When opened, cold water is supplied from the cold water outlet 12 to the mixing thermovalve 4, hot water is supplied from the hot water outlet 12 to the mixing thermovalve 4, and the mixing thermovalve 4 is supplied with hot water.
The mixture is mixed to the set temperature and is vigorously discharged from the injection nozzle 5.

[Effect of the idea]

The present invention is equipped with a cold water removal device that removes low-temperature hot water by having a heat-sensitive member and a valve operated by the heat-sensitive member. In addition to connecting to the valve, the water pipe is connected to the mixing thermo valve, and the injection nozzle for hot water injection is connected to the mixing thermo valve, which mixes hot water and tap water into water at an appropriate temperature, so it can be used in bathtubs and kitchens. By using a heat source device such as a hot water tank that supplies hot water, it is possible to use an existing heat source device or share a heat source device, and by using the water pressure or water pressure of the heat source device, the pump can also be omitted. This has the advantage that the hot water cleaning device can be configured at low equipment cost without installing a conventional expensive hot water cleaning device, and the running cost can also be reduced. In addition, since it is equipped with a cold water removal device, it can remove hot water that has cooled down in the piping from the heat source machine to the cleaning device, and for this reason, cold water is unexpectedly discharged from the injection nozzle. Since it is equipped with a thermo valve, hot water at a constant temperature can be discharged from the injection nozzle, allowing the hot water cleaning device to be used safely and comfortably. Since it is provided before the hot water and tap water are mixed, the cold water can be removed more quickly than when the cold water is removed after the hot water and tap water are mixed.
