本発明は、給＃温度をガス量により制御するようにした
ガス瞬間式給湯装置ｈ１所謂ガス比例式瞬間゛湯沸器に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas instantaneous water heater h1, a so-called gas proportional instantaneous water heater, in which the supply temperature is controlled by the amount of gas.
更に詳しくはガス比例式瞬間湯沸器の水流、スイッチシ
ステムに関する。More specifically, the present invention relates to water flow and switch systems for gas proportional instantaneous water heaters.
従来のガス比例式誕間湯沸器に使用されてぎた水流スイ
ッチは、水流スイッチでの差圧や水量によりスイッチの
ＯＮ、 ＯＦＦが決定されていた。The water flow switch used in conventional gas proportional water heaters determines whether to turn the switch on or off based on the pressure difference or water flow at the water flow switch.
このような、従来のものにおいては以下の点で問題があ
った。Such conventional devices have the following problems.
即ち、条件が
１、ガス比例式１量錫お１ｊ器で４号から１６号の比例
帯をもっている。That is, the condition is 1, the gas proportional type 1-volume tin-1j device has a proportional band of No. 4 to No. 16.

使用不能部分ができ実際にけ■、■式より７．８号から
しが火が眉かない。3. Inlet water temperature is 5°C to 25°C 4. If the minimum flow h required for operation with a conventional water flow switch is about 3.017 minutes, a) Set the set temperature to high (70"C). When set, if the inlet water temperature is 5''C, the output amount of No. 4 is 100 Kcal/min as a heat amount, so 100/(70-5) = 1.54 J/min-■(70-
5) X 3 = 19'5 Niba/min□■195/25
= No. 7.8 □■ ■ From the formula, under the above conditions, if the water heater has a flow rate of 1.541/min, the minimum flow rate for switch activation, even though the water heater has %7 < full capacity. Since the time is determined to be 3.017 minutes, there is an unusable area shown by the diagonal lines in the graph of Figure 2, and in fact, according to formulas ■ and ■, No. 7.8 mustard fire does not occur.
従って、冬場高温の湯を小量っがうということができな
い“ことがある。Therefore, it may not be possible to gulp a small amount of hot water in winter.

。(b) If the set temperature is revised to low (35'C), and the inlet water temperature is 25°C, then 100/(35-25)-=1017 minutes (35
-25) X 3 = 30I (caJ'/min -■1
00/3'-33.3℃, °, 25+33.3 = 58.3''C From the formula,
In order to obtain hot water at 35°C, a flow rate of 1 ozZ is required, but in reality, according to formulas ■ and ■, the fire starts in 3.017 minutes and the overflowing water temperature is the minimum capacity of the water heater. Line and 3.01
The intersection of the /minute lines is 5 8.3 ''C.
従って、Ｒ場においてぬるい湯を小量使用したい場合に
、実際には熱い湯しか′ｒ：ないので火傷全する危険性
が生じる。Therefore, when it is desired to use a small amount of lukewarm water in the R field, there is actually only hot water and there is a risk of burns.

よる。Next, connection to solar power is not possible with a general water flow switch. Reason No. 3.01 If water flows more than 1, it will definitely catch fire, so if hot water comes, no matter how high the temperature rises, the fire will continue to burn at the lowest number, so the thirst will θl. ) Eventually, the safety device will turn on and put out the fire. In other words, if a person comes to 80℃ hot water, the lowest capacity is set to 4, and the hot water is 3t! /min - Then the humidity increases by 100 3 J/min - 33.3"C, and the hot water temperature becomes 80 + 33.3 = 113.3 °C, 7
evening.
しかしこのシステムは設定温度と入水温度と流量により
演算して火ｋ ９ｕけるシステムなので、沸とうは生じ
ない。つまりソーラーとの接続が口」能である。However, this system calculates the temperature based on the set temperature, inlet water temperature, and flow rate to start the fire, so boiling does not occur. In other words, the connection to solar is the key.
