プの損傷をひきおこすことになる。2. Description of the Related Art Recently, in order to effectively use water resources, rainwater has come to be used for flush toilets, sprinklers, and the like. For this purpose, generally, the collected rainwater is stored in a rainwater tank, and when it is used, it is supplied to the location where it is used by an electric pump.However, when there is no rainfall or when there is little rainfall, the rainwater tank is used. The amount of water in the inside will decrease or disappear, and not only water cannot be used, but also the electric pump will be damaged.

１０−１５９１３６号公報により提案されている。Therefore, when the amount of water in the rainwater tank decreases,
It is conceivable to switch from using tap water to using tap water. As a device for this, there is a rain tank which detects the water level in the rain tank and automatically switches the use of rain water and tap water. It is proposed by the publication.

実用上種々の問題点がある。However, in this device, a water level drop in the rainwater tank is detected by a water level sensor, and the output signal of the control unit which receives the water level drop detection signal switches the water supply switching valve composed of an electrically operated three-way valve. Since it switches to the use of clean water in the sub water tank and also to the use of rain water by the same control system when the water level in the rain water tank rises, multiple parts such as a water level sensor, a water supply switching valve, and a control unit are used. Because it requires electrical wiring as well
Combined with the electric water supply switching valve, the manufacturing cost is high, and since these electric parts need to be kept in the power supply state at all times, it is not preferable in terms of energy saving, and there is a great risk of failure due to the electric system. ,
There are various problems in practical use.

A ball tap 26 is provided at the tip of a water supply pipe 25 connected to the water supply pipe 4, and the water in the tap water tank 24 is held at a predetermined water level h 1 to h 2 . 27 is an electric pump for water supply mounted on the rainwater tank 22,
Is the suction port, and 29 is the discharge port. Reference numeral 30 is a filter for filtering rainwater, and 31 is an overflow pipe for rainwater.

続してある。The floating ball type switching valve 1 is arranged in the rainwater tank 22 with the port A facing downward, and the lower portion of the rainwater tank 22 (more specifically, below the lowest water level H 2 of the rainwater tank described later). The water suction pipe 33 opening to the position A) is connected to the port A, and the water supply pipe 34 communicating with the lower portion of the tap water tank 24 (specifically, the position below the water level h 2 ) is connected to the port B, and the pump 2
The suction pipe 35 connected to the suction port 28 of No. 7 is connected to the port C.

The outlet 29 is connected to a hose for car washing, water sprinkling or initial fire extinguishing, and a water distribution pipe 36 such as a pipe to a use place such as a flush toilet, and the pump 27 is manually operated or automatically operated to distribute the water. Water is supplied from the water pipe 36 to the use side.

Since the valve body 10 is at the upper position and the valve body 10 is at the upper end position and opens the first communication path 5 and shuts off the second communication path 6, the rainwater in the rainwater tank 22 is absorbed by the water suction pipe 33, the ports A and C. The water is sucked by the pump 27 through the suction pipe 35 and supplied to the use side by the water distribution pipe 36.

When the water level reaches 2 ) or less, the valve body 10 shuts off the first communication path 5 and opens the second communication path 6, so that water is not absorbed by the water suction pipe 33 and the tap water from the tap water tank 24 Water is sucked by the pump 27 through the water supply pipe 34 and the ports B and C and supplied to the use side, so that water can be smoothly supplied even if the amount of rainwater decreases. When the water level in the tap water tank 24 falls below h 2 due to this water absorption, the tap water is replenished from the water supply pipe 25 by the ball tap 26, so that the water absorption can be performed without any trouble.

様である。When the water level in the rainwater tank 22 rises due to subsequent rain or the like, the floating ball 17 rises to drive the valve body 10 upward, and the water level H 1 at which the valve body 10 reaches the rising end position.
When the floating ball 17 moves up, the water absorption is switched to the port A side and only the rainwater is absorbed. For more details,
Water is absorbed from both ports A and B in parallel between the water levels H 1 and H 2 , and this is the same even when the water level is decreasing.

を容易におこなえる。As described above, in the floating ball type switching valve 1,
The float 17 moves up and down according to the fluctuation of the water level to drive the valve body 10 via the lever 15, and the ports A and B with respect to the port C are driven.
Switching between the rainwater supply and the tap water supply is performed, and this switching is automatically performed by the valve alone without the need for a separate electric water level sensor or control unit. It is possible to continue the smooth supply of water with a device with a simple structure without the need for power supply for. Also, since the floating ball type switching valve 1 is a 3-port valve type, the external piping when used as a three-way valve is simpler than that of other examples (4 port valve type) described later, and the piping is easy. Can be done.

供給を継続できるのである。The method of using the rainwater utilization tank 51 of this example is the same as that of the rainwater utilization tank 21 of the above-mentioned example, and when the floating ball 17 moves up and down due to the fluctuation of the rainwater level in the rainwater tank 22, the valve body 10 moves to the left and right. The point of driving and the supply of tap water to the pump 27 when the amount of rainwater decreases are separately supplied from the port D, and the supply of rainwater to the pump 27 when the amount of rainwater increases is separately supplied from the port C (see the above). In the example, the common port C is used), but the valve body 10 is driven by the lifting and lowering of the floating ball 17 in the same manner as in the above example by the raising and lowering of the floating ball 17 so that the first communication path 45 and the second communication path 45 The supply of rainwater and tap water is switched by opening and closing the path 46. This switching does not require a separate electric water level sensor or control unit, but is automatically performed by the valve alone, and fluctuations in the amount of rainwater. Can continue to supply water smoothly It is.
