る。In Figure 1, 16 is an aluminum metal base 1.
It is a copper-clad aluminum laminated board with an insulating layer 18 coated on the surface of 7 and a copper foil 19 coated thereon (hereinafter referred to as a laminate board), and a double-sided tape 20 for attachment to a hot water tank is attached to the bottom surface. ing. The copper foil 19 of the laminated board 16 is processed into a pattern as shown in FIG.
It is connected to the copper foil 19 at. The connection between the chip thermistor 21 and the signal line 23 at the end is covered with epoxy resin 24 for insulation as shown in FIGS. It is covered with a thin film 25 of Frethane resin to ensure insulation. The hot water amount sensor unit 26 configured in this way is attached to the long laminated substrate 1.
The entire lower surface of the hot water tank 6 is attached in close contact with the surface of the hot water tank 4.
従って、チップ形サーミスタ２１は熱伝導の良好な金属
製ベース１７を介して貯湯槽４と熱的に完全に一体化さ
れた構造となっている。Therefore, the chip-type thermistor 21 has a structure in which it is completely thermally integrated with the hot water tank 4 via the metal base 17 with good thermal conductivity.
取付方法は本実施例では両面テープ２０にて述べたが、

は言うまでもない。The mounting method was described using the double-sided tape 20 in this embodiment, but
Needless to say, the same effect can be obtained by attaching an aluminum tape or the like to the hot water storage tank 4 from the top surface of the hot water amount sensor unit 2e.
次に本実施例の湯温検出性能について第５図を用いて説

正ａｌＫ湯量をリモコン１０に伝えることができる。The actual hot water temperature at a position corresponding to each amount of hot water in the hot water storage tank 4 is shown as the displayed amount of hot water in axd. For example, to explain the state at point a, which corresponds to remaining D501, the temperature detected by the thermistor 5 of the conventional hot water quantity sensor unit 6 has a very slow thermal response as shown by the dotted line due to point contact, and is very slow compared to the actual hot water temperature. While there is a delay in T1 near the temperature displayed on the hot water level, the temperature detected by the chip thermistor 21 at the same position in the hot water level sensor unit 26 of this embodiment is only slightly different from the actual hot water temperature, as shown by the dotted line. The response delay T2 is also very low.
The correct amount of alK hot water can be transmitted to the remote control 10.
