Description

[Detailed Description of the Invention] The present invention relates to heating a toilet, and an object of the present invention is to heat a toilet by effectively utilizing the function of a toilet bowl with a cleaning function that cleans private parts of the human body after using the toilet bowl. It is something.

Conventional toilet heating has relied entirely on toilet seat heating, but this has the disadvantage that areas other than the buttocks are extremely cold.

The present invention effectively utilizes the pump, heating means, etc. of a toilet bowl with a cleaning function, and adds a hot water heater and water supply channel switching means to heat a wide range of areas with hot water without impairing the local cleaning function. This is to eliminate the shortcomings.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 3.

FIG. 1 is an external view of an embodiment of the toilet hot water heater of the present invention. 1 is the toilet bowl, 2 is the toilet room,
3 is a toilet seat, 4 is a toilet seat lid, 5 is a water tank, 6 is a box for storing a human body private part cleaning function, 7 is a cleaning nozzle for discharging cleaning water into the toilet compartment 2 to clean the human body private parts, 8 is the water tank 5 a suction pipe that sucks the water inside into the box 6;
9 is a hot water heater for heating the floor surface of the toilet; 10 is a water inlet of the hot water heater 9; 11 is a water outlet of the hot water heater 9; 12 is a water heater for supplying hot water in the box 6 to the water inlet 10; A circulation outgoing waterway 13 is a circulation return waterway for returning the water supply from the water outlet 11 to the box 6.

FIG. 2 is a structural diagram showing a heating state in the above embodiment. Components with the same numbers as in FIG. 1 are the same, and their explanation will be omitted. 14 is a water filter submerged in water in the water tank 5; 15 is an air vent joint; 16 is a pump; 17 is a heater; 18 is a heat exchanger that transfers the heat generated by the heater 17 to the water supply;
Reference numeral 9 denotes a three-way valve that switches the water supply channel from the cleaning nozzle 7 to the circulation channel 12, and in the illustrated heating state, the water supply is switched to the circulation channel 12 side.

In the above configuration, the feed water discharged by the pump 16 is heated by the heat exchanger 18 to an appropriate temperature for heating, and is sent to the circulation waterway 12 via the three-way valve 19. The heated water supply circulates through the hot water heater 9 from the water supply port 10 to heat the toilet. Water cooled by heat dissipation from the hot water heater comes out of the water outlet 11, passes through the circulation return passage 13, and is sent to the suction side of the pump 16 via the air vent joint 15, where it is circulated. Form a route. The role of the air bleed joint 15 is, in addition to the role of the joint as described above, when the hot water heater 9 is first installed, it also serves to bleed the air inside the hot water heater 9 while supplying water by operating the pump 16. have

FIG. 3 is a structural diagram showing a state of cleaning a private part of the human body in the above embodiment. The difference from FIG. 2 is that the water supply channel is switched to the cleaning nozzle 7 side by a three-way valve 19.

In the above configuration, the water in the water tank 5 is transferred to the water filter 1 by the operation of the pump 16.
4, heated by the heat exchanger 18 to an appropriate temperature for cleaning private parts of the human body, and discharged as fresh hot water from the cleaning nozzle 7 via the three-way valve 19 to clean the private parts of the human body. At this time, the circulation waterway 12 is closed by the three-way valve 19, so a hot water circulation path to the hot water heater 9 is not formed, and therefore the dirty hot water that has accumulated in the hot water heater 9 is removed. It is never released into the human body. However, since it only takes about 20 seconds to clean a person's private parts, there is no problem with heating. In addition, since the suitable temperature of hot water for heating and the suitable temperature of hot water for washing private parts of the human body are both about 40°C, the moment the three-way valve 19 switches to the washing nozzle 7, the washing nozzle 7
There is no danger of high-temperature water being released. In addition, the three-way valve is always kept in the state shown in Figure 3 when heating is not required.

As is clear from the above description, the toilet hot water heater of the present invention utilizes the pump and heating means in the conventional toilet bowl with a human body private parts cleaning function, and connects the hot water heater and the water supply channel to the cleaning nozzle to the hot water heater side. A switching means is added, and hot water is circulated to the hot water heater by the heater and pump during heating, and when cleaning private parts of the human body, the hot water circulation is stopped and hot water is discharged from the cleaning nozzle to perform cleaning as usual. Therefore, when washing, you can wash with fresh hot water, and you can heat a wide area of the toilet with hot water, not just the toilet seat like in the past, and the temperature of the hot water heater does not change even when washing, so the heating The effectiveness is improved and you can use the toilet comfortably even in winter. Moreover, since the pump and heating means that are essential for hot water heating are used for the conventional human body private part cleaning function, it has the advantage that hot water heating can be realized in a small size and at low cost.
