水として貯溜されるようになっている。In addition, in order not to use it for a long period of time or to prevent freezing damage to the piping in winter, the water in the bathtub 1 is discharged,
When the drain valve 11 is opened, the water in the self-priming pump 3 is drained from the drain port 3c through the drain pipe 9, so that all the water in the filtering device 2 is completely drained. Then, when tap water or hot water is supplied to the bathtub 1 from this state, the stored water in the bathtub 1 flows into the self-priming pump 3 through the first pipe 5, and the self-priming pump 3 is called. It is stored as water.
〈考案が解決しようとする課題〉 ところで、上記従来の濾過装置２の場合、次のような不
具合がある。<Problems to be Solved by the Invention> By the way, the conventional filtering device 2 has the following problems.
自吸式ポンプ３の吸入口３ａと浴槽１の吸込口１ａとが

止点は、浴槽１の還流口１ｂの高さ位置を越したところ
となる。Since the suction port 3a of the self-priming pump 3 and the suction port 1a of the bathtub 1 are located at substantially the same height, the first pipe 5 connecting the two has a rising portion 5a as shown in the drawing. I used the one. Therefore, the hot water inflow starting point into the self-priming pump 3 is a position where the water level in the bathtub 1 exceeds the height position of the rising portion 5a of the first pipe 5, and the hot water inflowing into the self-priming pump 3. The stop point is a position beyond the height position of the return port 1b of the bathtub 1.

る。As described above, the inflow period of the hot water into the self-priming pump 3 is H 1 from the height position of the rising portion 5 a to the height position of the reflux port 1 b of the bath 1. The dimension of H 1 is set to be short, for example, about 10 to 30 mm based on the relative height dimension between the bath 1 and the filtration tank 4, so that the self-priming is performed at a general water supply speed to the bath 1. There is a case where the amount of hot water flowing into the automatic pump 3 is considerably insufficient, and the self-priming pump 3 is air-locked, so that the pump action is lost.
本考案は、このような事情に鑑みて創案されたもので、
浴槽への給湯時に自吸式ポンプに十分な呼水を貯溜でき

An object of the present invention is to enable the self-priming pump to store a sufficient amount of priming water when hot water is supplied to the bathtub, and to realize a reliable operation of the self-priming pump.
〈課題を解決するための手段〉 本考案は、このような目的を達成するために、次のよう

る。The filtration device of the present invention includes a self-priming pump, a filtration tank, first and second pipes, a drainage pipe, and a bypass pipe, and the self-priming pump collects stored water in a storage tank. It sucks and sends it to the filtration tank, and then returns it to the storage tank. It has a suction port and a discharge port on the upper side, and a drain port on the lower side. The first pipe is the suction port of the self-priming pump. The port is connected to a suction port provided below the side wall of the storage tank, and the second pipe connects the discharge port of the self-priming pump and the return port provided above the side wall of the storage tank. The drainage pipe is connected to the drainage port of the self-priming pump and has a drainage valve in the middle thereof, and the bypass pipe is the self-priming pump side of the drainage pipe and the first drainage pipe.
The feature is that it connects the pipe and the middle.

されることになる。<Operation> In the present invention, the suction port of the bathtub is connected to the upper suction port of the self-priming pump, and is also connected to the lower drain port of the self-priming pump via the first pipe, the bypass pipe, and the drainage pipe. I am letting you. Since the first pipe, the bypass pipe, and the drainage pipe are arranged in this order from top to bottom, when the water level of the stored water in the bathtub exceeds the height position of the suction port when water is supplied to the bathtub. The water in the bathtub is guided from the suction port to the drain port of the self-priming pump through the first pipe, the bypass pipe, and the drain pipe, and is introduced into the self-priming pump.
Therefore, while the water level in the bathtub rises from the suction port to the reflux port of the bathtub, sufficient self-priming water is stored in the self-priming pump.
〈実施例〉 以下、本考案の実施例を図面に基づいて詳細に説明す
る。<Embodiment> An embodiment of the present invention will be described below in detail with reference to the drawings.
第１図は本考案の一実施例の濾過装置を示している。こ
の図において、従来例の第２図に示す部品、部分と同じ
ものに同一の符号を付してある。FIG. 1 shows a filter device according to an embodiment of the present invention. In this figure, the same parts and portions as those shown in FIG. 2 of the conventional example are designated by the same reference numerals.

ことである。In this embodiment, the configuration different from the conventional example is that the first pipe 5 and the drainage pipe 9 are connected by a bypass pipe 13, and the suction port 1a of the bathtub 1 is automatically connected through the first pipe 5, the bypass pipe 13, and the drainage pipe 9. That is, it is connected to the drain port 3c of the suction pump 3.

となっている。The bypass pipe 13 described above is substantially configured by a part of the fourth pipe 8. That is, in the fourth pipe 8, the middle of the portion connected to the first pipe 5 along the vertical direction is connected to the portion of the drain pipe 9 connected to the drain port 3c of the self-priming pump 3 along the horizontal direction. The portion of the fourth pipe 8 between the connecting portion of the fourth pipe 8 and the drainage pipe 9 and the connecting portion of the first pipe 5 and the fourth pipe 8 is the bypass pipe 13.
Has become.
次に、自吸式ポンプ３への呼水の流入動作を説明する。Next, the inflow operation of the priming water into the self-priming pump 3 will be described.

ンプ３に対して水が流入できなくなり、同様に、自吸式
ポンプ３の排水口３ｃからも水が流入できなくなる。When the water level in the bathtub exceeds the height position of the suction port 1a of the bathtub 1 due to the water supply to the bathtub 1, the bathtub water starts to flow from the first pipe 5 to the drain pipe 9 through the bypass pipe 13. Since the drain valve 11 of the drain pipe 9 is closed, water is stored in the portion up to the drain valve 11 and the fourth pipe 8
Also, while water is stored, the water flows into the self-priming pump 3 through its drain port 3c. Simultaneously with this inflow, the bath 1 from the discharge port 3b above the self-priming pump 3 through the second pipe 6
The air in the drainage pipe 9, the fourth pipe 8 and the self-priming pump 3 escapes to the side. Then, until the water level in the bathtub reaches the height position of the reflux port 1b of the bathtub 1, the water flows into the self-priming pump 3. After that, when the water level in the bathtub reaches the height position of the reflux port 1b of the bathtub 1, it flows into the middle of the second pipe 6, but there is no escape of residual air in the self-priming pump 3, Water cannot flow into the self-priming pump 3 from the second pipe 6, and similarly, water cannot flow from the drainage port 3c of the self-priming pump 3.
このようにして、自吸式ポンプ３内への給水がスムーズ

分に大きく設定される。In this way, water can be smoothly supplied to the self-priming pump 3, and a sufficient amount of priming water can be secured, so that the self-priming pump 3 can operate stably. By the way, during the hot and cold water inflow period to the self-priming pump 3, the interval H from the height position of the suction port 1a of the bathtub 1 to the height position of the reflux port 1b is H.
2 , and the size of this H 2 is set to a sufficiently large value of 100 to 110 mm.
