Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster-response toilet that can be flushed with a normal amount of flushing fluid in normal times and flushed with a small amount of flushing fluid in an emergency.

In buildings such as residences, lifelines such as water supply and sewerage systems are expected to malfunction in the event of a disaster such as an earthquake. In such an emergency, there is a problem that the flush toilet cannot be used at all.

Therefore, the present applicant has proposed a toilet that can be used both in normal times and in emergencies. For example, the toilet bowl described in Patent Document 1 is a toilet bowl that has an emergency discharge port that opens directly below the position where waste falls from the flush toilet, and discharges waste to the outside from the emergency discharge port in an emergency.

This emergency discharge port is normally sealed with a plug member, and is configured to be used by removing this plug member in an emergency. In other words, a floor opening with a diameter equal to or greater than that of the emergency discharge port is provided on the floor plate vertically below the emergency discharge port, allowing switching from the normal water washing type to the emergency gravity drop type.

On the other hand, Japanese Laid-Open Patent Publication No. 2002-100000 discloses a toilet device that discharges waste together with a small amount of accumulated water in an emergency. This apparatus is constructed such that in normal times, sewage is discharged through the drain trap channel, and in emergency, pooled water is stored in the bypass channel, and the sewage is discharged together with the pooled water.

Japanese Patent No. 4653232 JP 2020-117954 A

However, since the toilet described in Patent Document 1 switches to the gravity drop type in an emergency, the bowl portion in the toilet body gradually becomes dirty. In addition, there is also the inconvenience that the odor flows backward from the emergency discharge port, which is always open.

On the other hand, the toilet bowl device of Patent Document 2 is configured to discharge waste together with accumulated water through the bypass channel in an emergency, so it is difficult to wash the inside of the toilet bowl with the accumulated water.

That is, pooled water is stored in advance on the flapper valve, and when the flapper valve is opened by the user's operation, faeces are discharged to the sewage pipe through the bypass channel together with the pooled water. When the flapper valve is closed, cleansing water is supplied from the cleansing water tank until the surface of the pooled water reaches the predetermined height of the bypass channel again.

At this time, since the flapper valve is used with pooled water, it is necessary to reduce the volume and momentum of the pooled water in an emergency as compared to the cleaning water in normal times. Therefore, no consideration is given to washing the inside of the toilet bowl with this pooled water.

Moreover, this toilet device requires a switching device for switching the bypass passage, as well as many components such as an upstream switching valve and a downstream switching valve that interlock with the switching device. Therefore, the device itself has to have a very complicated structure as compared with a general toilet bowl. As a result, there are many problems such as not only an increase in manufacturing cost but also an increase in work processes when installing the apparatus.

Therefore, the present invention was created to solve the above-mentioned problems, and it is possible to wash the bowl with a normal amount of washing fluid in normal times, and to wash the bowl with a small amount of washing fluid in an emergency. The object is to provide a disaster-response toilet that can be provided in a configuration.

A first means of the present invention for achieving the above-mentioned object is a flush-type flushing type in which sewage is discharged to a sewage pipe P through a trap by supplying a normal flow rate of cleaning fluid from a faucet water pipe in normal times. In the toilet bowl 10, an emergency discharge port 12 is formed at a position at the bottom of the bowl 11 where waste falls, and a flapper valve 30 is arranged vertically below the emergency discharge port 12 to close the emergency discharge port 12 in normal times and open it in an emergency. It is equipped with a plug member 20 for cleaning the bowl 11 in an emergency and configured to directly discharge waste from the emergency discharge port 12 to the sewer pipe P through a discharge pipe 60 provided vertically below the flapper valve 30 in an emergency. An emergency water pipe 13 for supplying fluid is provided, and the amount of water from the emergency water pipe 13 is set to be smaller than the amount of washing supplied from the faucet water pipe 14 in normal times, and the emergency water pipe 13 This is a toilet bowl for emergency use , which pressurizes the washing fluid from the inside of the bowl 11 to wash the inside of the bowl 11 while rotating it, and then discharges it from the emergency discharge port 12 through the discharge pipe 60 to the sewage pipe P.

The emergency water supply port 12 of the second means is configured to supply cleaning fluid from a water supply tank 40 used in normal times.

The emergency water supply port 12 of the third means is configured to supply cleaning fluid from an emergency water supply tank 50 used in an emergency.

According to the present invention, washing can be performed with a normal amount of washing fluid in normal times, and washing can be performed with a small amount of washing fluid in an emergency. As a result, a clean toilet bowl can be used even in an emergency.

In addition, it can be provided with a simpler configuration than conventional emergency toilets, suppressing increases in manufacturing costs, and facilitating the installation process.

FIG. 4 is a side cross-sectional view of essential parts showing another embodiment of the present invention; FIG. 4 is a side cross-sectional view of essential parts showing another embodiment of the present invention;

The disaster-response toilet bowl of the present invention is a toilet bowl that can be used both in normal times and in emergencies. That is, in a faucet-type toilet bowl 10 that discharges waste through a trap, an emergency discharge port 12 is formed at a position where waste is dropped. Then, in an emergency such as a disaster when the water supply is cut off, the plug member 20 covering the emergency discharge port 12 is removed and waste is discharged outside through the emergency discharge port 12 (see FIG. 2).

Furthermore, an emergency water pipe 13 used in an emergency is provided in the vicinity of the faucet water pipe 14 that supplies cleaning fluid in normal times (see FIG. 1). In an emergency, the faucet water pipe 14 is closed and the emergency water pipe 13 is opened. This emergency water pipe 13 sets the amount of cleaning fluid to be supplied to be smaller than the amount of cleaning fluid supplied during normal times. For example, if the cleaning amount of the cleaning fluid supplied in normal times is several liters, the cleaning amount of the cleaning fluid supplied through the emergency water pipe 13 is set to approximately 300 cc to 500 cc.

In this way, the cleaning fluid supplied in a small amount is pressurized from the emergency water pipe 13 and supplied so as to clean the inside of the bowl 11 while rotating. Any means can be selected as the means for pressurizing the cleaning fluid.

For example, as shown in FIG. 1, when the water supply tank 40 used in normal times is positioned higher than the toilet bowl 10, the water supply tank 40 can be used as an emergency water supply tank 50 by connecting the emergency water supply port 12. Become. In this case, by making the opening diameter of the emergency discharge port 12 narrower than that of the faucet water pipe 14, the pressure of the cleaning fluid during supply can be increased. Moreover, since the amount of cleaning to be supplied is reduced, the cleaning fluid remaining in the water supply tank 40 can be divided and used many times.

Further, as shown in FIG. 3, an emergency water supply tank 50 for use in an emergency may be provided separately, and a submersible pump 51 may be installed in this emergency water supply tank 50 . By operating the switch 52 , it becomes possible to supply the cleaning fluid pressurized by the submersible pump 51 from the emergency discharge port 12 . Reference numeral 53 in the figure is an outlet.

Furthermore, as shown in FIG. 4, by installing an emergency water supply tank 50 formed separately from the water supply tank 40 at a position higher than the position of the emergency discharge port 12, the water pressure in the emergency water supply tank 50 allows a larger amount of washing to be performed. The fluid can be supplied under pressure.

The pressurized cleaning fluid supplied from the emergency discharge port 12 flows to the bottom of the bowl 11 while rotating inside the bowl 11 due to the momentum supplied into the bowl 11. Therefore, even a small amount of the cleaning fluid does not stain the bowl 11. can be washed.

Tap water is generally used as the cleaning fluid. In addition, it is also possible to store rainwater, used waste water, etc. in the emergency water supply tank 50 and use it as a cleaning fluid to be used in an emergency. In this way, when installing the emergency water supply tank 50 in addition to the water supply tank 40 used in normal times, an arbitrary amount of emergency water supply tank 50 can be installed according to the installation situation.

Furthermore, it is also possible to use a foam cleaning agent or a foaming machine used in foam cleaning toilets (not shown). In this case, the inside of the bowl 11 is washed with the foamy washing fluid supplied from the emergency discharge port 12 .

On the other hand, a flapper valve 30 is installed vertically below the emergency discharge port 12 to discharge waste together with the cleaning fluid supplied to the bowl 11 from the emergency water pipe 13 (see FIG. 1). This flapper valve 30 is used only in an emergency, and the flapper valve 30 can be freely selected, for example, using the flapper valve 30 used in general portable toilets.

Since the flapper valve 30 is arranged under the emergency discharge port 12 from which the plug member 20 is removed, it prevents odor from flowing back from the emergency discharge port 12 opened in an emergency (see FIG. 1). Furthermore, sanitary pests in the drain pipe can be prevented from entering the toilet.

In the illustrated example, a discharge pipe 60 is provided vertically below the flapper valve 30 to discharge directly to the sewage pipe P (see FIG. 1). It is also possible to connect this discharge pipe 60 to a waste tank or the like used for emergencies (not shown).

It should be noted that the configuration of each part of the present invention is not limited to the illustrated example, and can be changed to other shapes within the scope of not changing the gist of the present invention.
