Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a local cleaning device provided in a flush toilet.

[0002]

[Prior art and its problems]

 Conventionally, a toilet bowl with a local cleaning device has a structure as shown in the sectional view of FIG. 3, and a raw tank 2 for storing flush water is installed upright at the rear of the toilet body 1, 2 is supplied with water from an external water pipe through a water stopper 3, and a ball tap 4 provided in the low tank 2 is connected with a tank 5 in a drooping manner. Further, a water supply hose 6 is connected to the tank 5. The supplied water is heated in the hot water tank 7 connected to the water supply hose 6, and the hot water is pumped to the nozzle 9 by the operation of the electromagnetic pump 8 above the hot water tank 7, and the hot water is supplied from the nozzle 9 to the user. The structure is such that it is ejected toward the local area.

In such a type of toilet bowl, as shown in the block diagram of FIG. 4, a stop cock 3, a ball tap 4, a tank 5, a water supply hose 6, a hot water tank 7, an electromagnetic pump 8, and a nozzle 9 are arranged in this order. It has a structure in which water flows, and when hot water is jetted from the nozzle 9 and the inside of the hot water tank 7 becomes empty, it is necessary to reopen the stop cock 3 to supply water to the hot water tank 7. There was a problem that when hot water was jetted from the hot water, the hot water disappeared and it was impossible to jet hot water for a long time.

Further, in the toilet bowl of the type shown in FIG. 5, a local cleaning device is incorporated in a case 12 provided on the upper part of the toilet bowl 11. This local cleaning device comprises a main valve 13 and a pressure adjusting valve. 14, a water quantity switching valve 15, a hot water tank 16, a vacuum breaker 17, a shower switching valve 18, a charm switching valve 19, a shower nozzle 20, and a charm nozzle 21, which are supplied from the outside. As shown in FIG. 6, the water supply is made to flow from the main valve 13 to the pressure control valve 14, and is further supplied to the hot water tank 16 through the water quantity switching valve 15, and the hot water further passes through the vacuum breaker 17 and the shower switching valve 18 or the charm. It branches into the switching valve 19 and is ejected from the shower nozzle 20 or the charm nozzle 21, respectively.

In such a structure, since the hot water is jetted from the nozzle by utilizing the water pressure of the water supplied from the outside, it is sufficient in an area where the water pressure is low and the top floor of a condominium or the like. However, there is a problem that sufficient hot water cannot be jetted from the shower nozzle 20 and the charm nozzle 21 because no sufficient water pressure can be obtained.

Further, in the local cleaning apparatus of the type shown in FIG. 7, the water is supplied in the order shown in the block diagram of FIG. That is, the water supplied from the external water pipe is decompressed by the pressure reducing valve via the water stopcock and stored in the auxiliary tank 30, and further supplied from the auxiliary tank 30 to the hot water tank 32 through the pump 31. The hot water heated in the hot water tank 32 is supplied to each nozzle 34 via the switching valve 33. In such a structure, since high-pressure water is supplied from the pump 31 into the hot water tank 32, a strong water pressure is applied to the hot water tank 32, and the hot water tank 32 is easily damaged.

[0007]

[Means for Solving the Problems]

 The present invention has been devised in view of the above-mentioned conventional problems, and it is possible to continuously eject hot water from a nozzle without being affected by water pressure or the like, and without damaging the hot water tank. The purpose of the present invention is not to provide a local cleaning device that can be used, and its gist is to provide a nozzle that ejects hot water toward the user's local area, a hot water tank that produces hot water, a pump that pumps hot water, and a water pressure reduction. The pressure reducing valve is provided so that the water supplied from the outside through the water stopcock that is always open flows through the pressure reducing valve, the hot water tank, and the pump in this order.

[0008]

[Function] Water supplied from an external water pipe reaches the pressure reducing valve through the water stopcock, is reduced in pressure by the pressure reducing valve, is then supplied to the hot water tank, is heated in the hot water tank to become hot water, and is then pumped. Since it is supplied to the nozzle via the nozzle and jetted from the nozzle, hot water can be jetted well from the nozzle without being affected by the water pressure of the external water pipe, and water is supplied to the hot water tank via the pressure reducing valve. The hot water tank will not be damaged, and if the water stopcock is kept open at all times, water will be continuously supplied to the hot water tank, and hot water will be continuously generated in the hot water tank. Warm water can be jetted from the nozzle for a long time.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional configuration diagram of a toilet bowl with a local cleaning device of this example, and FIG. 2 is a block diagram showing a flow order of water supply.

In the figure, a low tank 2 is erected on the rear upper surface of the toilet body 1, and a water stopper 3 is provided outside a ball tap 4 mounted in the low tank 2. 3 is connected to an external water pipe, and in this example, the water stopcock 3 is always held in an open state. On the downstream side of the water stopcock 3, a water supply hose 6 is branched from the ball tap 4 along the outer wall of the low tank 2, and a water reducing hose 6 is connected to the end of the water supply hose 6. The hot water tank 7 for generating hot water is connected to the downstream side of the pressure reducing valve 10, the electromagnetic pump 8 is connected to the downstream side of the hot water tank 7, and the nozzle 9 is connected to the downstream side thereof. It has a structure.

In such a structure, the water supply supplied from the external water pipe passes through the water stopcock 3 in an open state, and is branched to the water supply hose 6 and the ball tap 4 to supply the water supply hose. The water supplied to the No. 6 side is decompressed by the decompression valve 10 and then flowed into the hot water tank 7. Therefore, the water pressure is not so much applied to the hot water tank 7, and the hot water tank 7 is prevented from being damaged by the water pressure. Further, since the hot water in the hot water tank 7 is pressure-fed to the nozzle 9 side by the operation of the electromagnetic pump 8, the hot water having a good fountain pressure is jetted from the nozzle 9 to the local part of the user.

Further, since the water stopcock 3 is always opened, the hot water is continuously supplied to the hot water tank 7 through the water supply hose 6 and the pressure reducing valve 10 in succession. Even when the hot water is used for a while, the hot water can be continuously generated in the hot water tank 7 and supplied to the nozzle 9 side, and the hot water can be used for a long time.

As described above, in this example, the hot water tank 7 is not damaged by the water pressure, and there is no conventional problem that the fountain pressure from the nozzle 9 cannot be obtained due to the decrease in the water pressure. There is no possibility that the tank 7 will become empty and the hot water cannot be used, and a good condition of use can be obtained with all the conventional problems cleared.
