【考案の詳細な説明】
この考案はガス湯沸機等の内部へ組込み、温湯
の流量積算値を翼車式流量計で計測し、計測した
流量積算値により、前記ガス湯沸機等への制御信
号でガス湯沸機等を最適状態に制御する為の流量
計に関する。[Detailed description of the invention] This invention is installed inside a gas water heater, etc., measures the integrated flow rate of hot water with a blade wheel type flow meter, and uses the measured integrated flow value to send information to the gas water heater, etc. This invention relates to a flow meter for controlling gas water heaters, etc. to optimal conditions using control signals.
本件考案の機器組込型流量計は湯沸機等の内部
に組込む為、外形寸法を小さく、かつ組込に便利
な形状寸法にする必要があり、更に正確度の保証
は水道メータ並の値に維持する必要のある流量計
を提案するものである。 Since the device-embedded flowmeter of this invention is to be built into a water heater, etc., it needs to have a small external size and a shape and size that is convenient for installation.Furthermore, the guaranteed accuracy is comparable to that of a water meter. This paper proposes a flow meter that must be maintained at
更に、本考案による流量計は小型にもかかわら
ず、通常の水道メータの耐圧17.5（Kg／cm2）に耐
える構造でなければならないものである。 Furthermore, although the flow meter according to the present invention is small, it must have a structure that can withstand a pressure resistance of 17.5 (Kg/cm 2 ) of a normal water meter.
従来はガス機器用の小型流量計として例えば
（実公昭56−41215）に示された流量計があつたが
耐圧も低くく、また流量を積算できるものでなか
つた。 In the past, there was a flowmeter shown in (Japanese Utility Model Publication No. 56-41215) as a small flowmeter for gas appliances, but it had low pressure resistance and was not able to integrate the flow rate.
従つて本件考案で提案する流量計としては採用
できないものであつた。本件考案の流量計は流量

知の磁気センサ７ａで電源を使用して電気的に流
量積算する流量計としたものである。 Therefore, it could not be adopted as the flowmeter proposed in this invention. Since the flowmeter of the present invention controls the gas water heater based on the integrated flow value, it requires the integrated flow value, so in order to keep it compact, a known magnetic sensor 7a is used to electrically measure the flow rate using a power source. This is a flow meter that performs integration.

As shown in the internal cross section of the figure, the impeller 4 is made of plastic, has a short length, and is molded to be lightweight. Furthermore, in order to make the structure more compact, the flow rate is counted using a separately provided (not shown) electronic circuit 11 of a known digital clock type, and a magnet 7 is fixed to the shaft of the impeller 4, A magnetic sensor 7a is arranged above with a slight gap therebetween.

線である。 The lower casing 3 is made of resin because it is more economical to mold it from synthetic resin in view of its small size, light weight, and internal measuring chamber (blade wheel storage chamber). However, due to dimensional restrictions to make it smaller, the inner thickness of the case 3 cannot be made sufficiently, so the pressure resistance is 17.5 (Kg/kg).
cm 2 ) was difficult to guarantee. Therefore, the problem was solved by devising a structure in which the upper cover 3a, which has a large pressure-receiving area, and the bottom surface 3b of the lower casing 3 are covered with a metal reinforcing plate 5. Note that 7b is a lead wire of the magnetic sensor 7a.

ようにしてある。 In the end, it has a U-shape with two ribs 5 on each of the upper and lower flat parts.
A metal reinforcing plate 5 formed by providing a is fastened with two bolts 10 to form a casing 12. Therefore, it is considered that the reinforcing plate 5 has a great reinforcing effect on the upper lid 3a. In the center of the flow path of the upper lid 3a, there is a seventh
As shown in the figure, a tongue-like adjuster 8 is slidably in contact with the adjuster 8 so that it can be rotated left and right, and by changing the angle of the tongue 8a with respect to the direction of water flow (for example, 90 degrees) (The flow is obstructed and the rotation of the impeller becomes slow.) The instrument error of the flow meter of the present invention can be adjusted.

る。 A regulator window 6 is provided on the upper surface of the metal reinforcing plate 5, and the hole diameter of the window 6 is larger than that of the regulator 8.
The head diameter of the regulator 8 is smaller than that of the regulator 8, and a reinforcing plate 5 is used to prevent the regulator 8 from coming off upward due to water pressure. (Refer to Figure 7) As shown in the perspective view in Figure 6, there is a slotted groove 8b on the top surface of the head of the tongue-like adjuster 8, so that the instrument difference can be adjusted from the outside of the case using a small flathead screwdriver. can. Also, since the minus groove 8b is provided directly below the tongue 8a in the same direction as the lower tongue 8a, the tongue 8 can be rotated left and right with a screwdriver.
It has the advantage of making it easy to grasp the angle of a with respect to the water flow.

向上することができた。 With a flow meter configured in this way, it is easy to integrate it into a gas water heater, and the flow rate can be integrated electrically using the power supply inside the gas water heater, so it is possible to calculate the integrated flow value, which was not possible before. We were able to properly control the water heater and improve its performance.
