圧縮機CMからの高温ガスが送られる。The growth of plate water on the lower surface of the ice making plate 2 is approximately 30 minutes to 60 minutes.
The ice grows to a sufficient size in minutes, and a drop in the level of the water tank 5 due to the growth of the ice is detected by the detection switch S1, that is, the detection switch S1 is opened to release the self-holding of the relay X1, and the normally open contact X1 -2 opens, thereby circulating pump P
M is stopped, water circulation is stopped, and normally closed contact X1
-3 opens the hot gas valve HV, and high temperature gas from the compressor CM is sent to the evaporator 8.
また同時に、常閉読点X1−3の閉成により給水電磁弁
wvは開弁され、外部水道系から貯水槽5に給水される
。At the same time, the water supply solenoid valve wv is opened by closing the normally closed reading point X1-3, and water is supplied to the water tank 5 from the external water supply system.

ているカットヒータH2に落下する。On the other hand, since the high temperature gas from the compressor CM is sent to the evaporator 8, the ice making plate 2 is warmed, and the ice that has grown into a plate shape melts at the contact part with the ice making plate, falls under its own weight, and is placed below it. It falls onto cut heater H2.
製氷板より氷が落下すると、製氷板の温度が急激に上昇

一方、落下した氷はカットヒータH2によって20〜3
0個の角氷片に融断され、貯水箱17が置かれている場
合には一部が、いない場合には全部が、融解槽9に落下
収容され、ここでヒータH1で融解され、清水として貯
留される。On the other hand, the fallen ice is cut by cut heater H2 to 20 to 3
It is melted into 0 ice cubes, and when the water storage box 17 is placed, a part of it is placed, and when it is not, all of it is dropped into the melting tank 9, where it is melted by the heater H1, and fresh water is released. It is stored as .
前記融解槽9内の清水は、必要なときに使用に供される
ものであるが、前記加熱用ヒータH1が常時オンにされ
ていると、水が温められ、飲料に適さないものになるば
かりか、細菌等の増殖の恐れがある。The fresh water in the melting tank 9 is used when necessary, but if the heater H1 is always on, the water will be heated and will become unsuitable for drinking. Otherwise, there is a risk of growth of bacteria, etc.
したがって融解槽9内の清水温度は常に10℃〜0℃に
保持する必要がある。Therefore, the temperature of fresh water in the melting tank 9 must always be maintained at 10°C to 0°C.
それがため、前記製氷清水機においては、融解槽9の所
定部位に水温検知サーモTh2が配設され、水温が上昇
したとき、前記ヒータH0をオフにし、融解されずに残
されている氷片の潜熱によって槽内水温が冷却されるよ
うになっている。Therefore, in the ice making water machine, a water temperature detection thermometer Th2 is disposed at a predetermined part of the melting tank 9, and when the water temperature rises, the heater H0 is turned off and the ice chips remaining unmelted are removed. The water temperature inside the tank is cooled by the latent heat of the tank.
また槽内水温を一定に保つ目的で、槽内の水が満杯にな
ったときにそれを溢流排除する手段が考えられるが、そ
れは清水の無駄な消費となるので好ましくない。Further, in order to keep the water temperature in the tank constant, it is possible to consider a method of overflowing and discharging the water in the tank when it is full, but this is not preferable because it results in wasteful consumption of fresh water.
それがため前記構成にあっては、溢流水位から若干下っ
た部位に水位検知サーモTh1が配設され、水位が所定
水位に達したとき、製氷機構の操作が停止されるように
なっている。Therefore, in the above configuration, the water level detection thermometer Th1 is arranged at a location slightly below the overflow water level, and when the water level reaches a predetermined water level, the operation of the ice making mechanism is stopped. .
この水位検知サーモTh1はその動作を確実なものとす
るため、予熱ヒータH3で水位検知感温部を温めておき
、水位の上昇に伴い、水位検知感温部が急激に冷される
ようになっている。In order to ensure reliable operation of this water level detection thermometer Th1, the water level detection temperature sensing part is heated by the preheating heater H3, and as the water level rises, the water level detection temperature sensing part is cooled down rapidly. ing.
さらにまた前記水位検知サーモTh1および水温検知サ
ーモTh2は、第3図の回路により、下記表に示すよう
に、連続作動されるようになっている。Furthermore, the water level detection thermometer Th1 and water temperature detection thermometer Th2 are continuously operated by the circuit shown in FIG. 3 as shown in the table below.
すなわち「水温が10℃以上で水位が低い」ときには第
3A図の回路が形成され、「水温が10℃以下で水位が

上のときには引続き製氷運転が続けられ、生成した氷片
により、槽内の水温が引下げられ、その水温が10℃以
下になるまで製氷運転が行われたあと、はじめてその運
転が止められる。In other words, when the water temperature is 10°C or higher and the water level is low, the circuit shown in Figure 3A is formed, when the water temperature is 10°C or lower and the water level is low, the circuit shown in Figure 3B is formed, and when the water temperature is 10°C or higher, the circuit shown in Figure 3B is formed. When the water level is high G2I, the circuit shown in Figure 3C is formed, and when the water temperature is 10°C or less and the water level is high, the circuit shown in Figure 3D is formed.When there is sufficient water in the tank, Ice-making operation is stopped only when the water temperature is below 10℃, and even if the water level is sufficient, if the water temperature in the tank is above 10℃, ice-making operation continues, and the generated ice pieces lower the water temperature in the tank. The ice-making operation is continued until the water temperature drops to below 10°C, and then the operation is stopped.
そしてそのときの余剰水は溢流により排出する。The excess water at that time will be discharged by overflow.
また槽内水位が低い場合には、製氷運転は引続き行われ
るが、水槽内の水温によってヒータH1はオン・オフに
制御される。Furthermore, when the water level in the tank is low, the ice making operation continues, but the heater H1 is controlled to be turned on or off depending on the water temperature in the tank.
前記水位検知サーモTh1は、これを槽の内面に設ける
と、ゴミや汚れなどが付着するおそれがあり、また槽内
の洗浄に邪魔になるので、槽の外面に設けるようにしで
あるが、元来この種のサーモスタットは感度が鈍いうえ
、槽内には冷却貯留された清水があるため、槽目体も冷
され、水位の正確な検知に劣るところがあるが、これに
予熱ヒータH3を共同させることにより、上記の欠点は
解消される。The water level detection thermometer Th1 is installed on the outside of the tank because if it is installed on the inside of the tank, there is a risk of dust and dirt adhering to it, and it will also get in the way of cleaning the inside of the tank. Traditionally, this type of thermostat has low sensitivity, and since there is cooled and stored fresh water in the tank, the tank body is also cooled, making it less accurate in detecting the water level, but this is combined with the preheating heater H3. This eliminates the above drawbacks.
すなわち、第4図において、融解槽9の水位りの変化に
対して水位検知サーモTh□の部位の変化についてみる
と、予熱ヒータH3のない場合には、第5図に示すよう
に、水位の変化に対して温度の変化が小さいため、設定
水位り。That is, in FIG. 4, if we look at the change in the water level detection thermometer Th□ with respect to the change in the water level in the melting tank 9, if there is no preheater H3, the water level will change as shown in FIG. The water level is set because the change in temperature is small compared to the change in temperature.
に対して誤差が大きくなり、正確な水位検知が困難とな
るが、水位検知サーモTh1の下に、僅かな間隙9(約
5關)をとって予熱ヒータH3が配設されている場合に
は、第6図に示すように、その部位に槽内清水のないと
きには、その槽壁部分が温められており、水位が次第に
上昇して設定水位り。However, if the preheater H3 is placed below the water level detection thermometer Th1 with a small gap 9 (approximately 5 degrees), As shown in FIG. 6, when there is no fresh water in the tank at that location, the tank wall is warmed and the water level gradually rises to the set water level.
に近づくと、その上昇水によって急激に熱が奪われ、水
位の変化に対して急激な温度変化が生じるので、より正
確な水位を水位検知サーモTh1で検知することができ
る。When the temperature approaches , heat is rapidly removed by the rising water, and a rapid temperature change occurs in response to a change in water level. Therefore, a more accurate water level can be detected by the water level detection thermometer Th1.
次に融解槽9に設けられる水温検知サーモTh2につい
てみると、水の比重は4℃のときが最も太き(、氷と水
とが混在している状態では、氷が水面にあるため、水面
付近が0℃であっても槽底部位は4℃になっており、し
かもそのことは氷片の混在量や水位の高低に拘わらず、
常に同じ状況となる故、水温検知サーモTh2は槽底部
位に設置し、4℃〜5℃にて動作するものが適している
。Next, looking at the water temperature detection thermometer Th2 installed in the melting tank 9, we find that the specific gravity of water is highest at 4°C (when ice and water are mixed, the ice is on the water surface, Even if the temperature near the tank is 0℃, the temperature at the bottom of the tank is 4℃, and this is true regardless of the amount of ice chips mixed in or the height of the water level.
Since the situation is always the same, it is suitable that the water temperature detection thermometer Th2 is installed at the bottom of the tank and operates at 4°C to 5°C.
