る。 Next, the operation will be explained. A conventional water supply tank used for a humidifier or the like is constructed as described above, and the water 8 to be humidified is supplied from the water supply port 9 through the water supply pipe 6 to the humidifier 7, and the water level in the water supply tank 1 is lowered A. When the temperature is below, the float switch 5 is activated, the solenoid valve 3 is turned on, and water 8 is supplied into the water supply tank 1. Further, as shown in Fig. 4, when water 8 is supplied into the water supply tank 1 and the water level becomes higher than B, the float switch 5 is activated again, and the solenoid valve 3 is activated again.
cut. By repeating this operation, water 8 can be constantly supplied to the humidifier 7 at low water pressure.

In the conventional water tank as shown above, solenoid valve 3
Alternatively, when the solenoid valve 3 is continuously opened due to a failure of the float switch 5, the amount of water that can overflow from the cylindrical weir 12, that is, the overflow capacity Q 0 is determined by dividing the height of the outer wall of the water tank 1 by h 1 and the height of the outer wall of the cylindrical weir 12. When the height is h 2 , each height difference (h 1 − h 2 ) is △h, and the circumference of the cylindrical weir 12 is b, then Q 0 =μ2/3b△h√2△, and <μ is Shape factor of weir > If water supply amount Q 1 from water supply port 4 is constant, Q 1 ≦
If Q is not 0 , water will overflow from water tank 1. Therefore, it can be said that the larger the overflow capacity Q 0 is, the more preferable it is, but in the conventional cylindrical weir 12, the circumferential length b is limited by the internal dimensions of the water tank 1, and the weir shape factor μ also depends on the cylindrical shape. In this case, the overflow flow is constricted toward the center, so compared to a straight weir,
It becomes quite small. Therefore, in order to increase the overflow capacity Q0 , it is necessary to increase the height difference △h, but △h
In order to increase the height, the outer wall height h i of the water tank 1 must be increased, which leads to an increase in the size of the water tank 1.
この発明は、上記のような問題点を解消するた
めになされたもので、給水タンク１を大きくする
事なく溢水能力Q0を増加できる装置を得ること
を目的とする。 This invention was made to solve the above-mentioned problems, and aims to provide a device that can increase the overflow capacity Q 0 without increasing the size of the water tank 1.

The water supply tank according to the present invention has a water storage chamber provided with a water supply port and a water supply port, and an overflow chamber provided with an overflow port, which are divided by an overflow weir, and the cross-sectional shape of the overflow weir is formed in a zigzag shape. The above purpose is achieved by increasing the total length of the weir.

In the water supply tank of the present invention, by forming the cross-sectional shape of the overflow weir in a zigzag shape, the total length of the weir is increased, and the amount of overflow at the same water level difference is increased.In other words, the size of the water supply tank is increased. Make smaller.

An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, 21 is a zigzag-shaped overflow weir with a zigzag cross-sectional shape, 22 is an overflow chamber partitioned by the zigzag overflow weir 21, and 23 is the overflow chamber 22. This is an overflow port drilled at the bottom.

筒堰の場合のμに較べかなり大きな値となる。 In the water supply tank configured as described above, if the solenoid valve 3 or the float switch 5 is continuously opened due to a failure, the water level rises and overflows the overflow weir in the zigzag pattern described above, resulting in an overflow chamber. 2
2 and is discharged from the overflow port 23 through the overflow pipe 10 to a drain pan or the like. This flooding capacity
As in the case of a cylindrical weir, Q 0 can be found as The shape factor μ is a considerably larger value than μ in the case of a cylindrical weir.
（但し、双方の堰の断面形状は同一とした場合）

水タンクの外壁高さと堰の高低△ｈの最小値を求
めると、次式となる。(However, if the cross-sectional shapes of both weirs are the same)
Therefore, in a zigzag-shaped overflow weir, the total length b can be made larger, so the overflow capacity Q 0 is smaller than that of a cylindrical weir.
Significantly improved. Further, the minimum value of the outer wall height of the water supply tank and the height △h of the weir is calculated from the maximum water supply amount Q M as follows.
即ち、実機における高低差△ｈは、上記〔２〕
式で求められる値よりも大きくする必要がある。 In other words, the height difference △h in the actual machine is the same as [2] above.
It needs to be larger than the value calculated by the formula.

ンに排水する事ができる。 That is, However, in reality, if we consider the installation accuracy (tilt) of the water tank 1 and the ripples on the water surface due to water supply, we can multiply the formula [3] by the safety factor, By doing so, water can be reliably drained from the outer wall of the water supply tank 1 to the drain pan via the overflow pipe 10 without overflowing.

As described above, according to the present invention, by dividing the inside of the water supply tank with an overflow weir having a zigzag cross-sectional shape and providing an overflow chamber, the water supply tank can be made smaller and its reliability against overflows can be improved. I was able to get a high water tank.
