酸ソーダ発生器に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sodium hypochlorite generator that easily produces sodium hypochlorite mainly used for sterilizing and disinfecting foods.
［従来の技術］
次亜塩素酸ソーダ発生器は、生成槽に受容され

成する装置である。しかし、従来におけるこの種
の発生器は、溶液の貯蔵量が少なく、生成槽を大
きくすれば食塩水の電気分解に要する時間が長く
なる欠点がある。[Prior Art] A sodium hypochlorite generator is a device that electrolyzes saline water received in a generation tank to generate a sterilizing solution of a predetermined concentration. However, conventional generators of this type have the drawback that the amount of solution stored is small, and the larger the generation tank, the longer the time required for electrolysis of the saline solution.
このため同出願人は、前回実願昭62−21067号
において第２図に示すような次亜塩素酸ソーダ発
生器を出願している。この発生器は、食塩水１を
受容する生成槽２、液内に浸漬された一対の電極
３，４、電磁弁５及び貯蔵タンク６から構成され
ている。従つて、生成槽２に一定量の食塩水１を
注入して電源を入れると、電極３，４により食塩
１は次式のように分解して次亜塩素酸ソーダ
（NaClO）が得られる。 For this reason, the same applicant applied for a sodium hypochlorite generator as shown in FIG. 2 in the previous Utility Application No. 1982-21067. This generator consists of a generation tank 2 that receives a saline solution 1, a pair of electrodes 3 and 4 immersed in the solution, a solenoid valve 5, and a storage tank 6. Therefore, when a certain amount of salt water 1 is injected into the generation tank 2 and the power is turned on, the salt 1 is decomposed by the electrodes 3 and 4 as shown in the following equation to obtain sodium hypochlorite (NaClO).
NaCl＋H2O→NaClO＋H2
また、所定濃度に達した溶液は、電磁弁５の開
放により順次貯蔵タンク６に送られて使用時まで
貯蔵される。 NaCl+H 2 O→NaClO+H 2 Furthermore, the solution that has reached a predetermined concentration is sequentially sent to the storage tank 6 by opening the solenoid valve 5 and stored until use.
［考案が解決しようとする問題点］
しかし、次亜塩素酸ソーダは不安定であるため
時間と共に分解し易く、徐々にその濃度が低下す

場合、生成槽２からの新しい溶液が所定濃度を有
していても、これらが貯蔵タンク６に送られると
既に貯蔵されている低濃度の溶液と混合して溶液
全体の濃度も常時低下することになる。[Problems to be solved by the invention] However, since sodium hypochlorite is unstable, it tends to decompose over time, and its concentration gradually decreases. Therefore, in the case of the generator of FIG. 2, even if the fresh solutions from the generation tank 2 have a given concentration, when they are sent to the storage tank 6 they mix with the already stored lower concentration solutions. Therefore, the concentration of the entire solution will always decrease.
本考案は、かかる事情に鑑みてなされたもので
あり、その目的は、貯蔵されている溶液の濃度低
下をできるだけ抑制し得る次亜塩素酸ソーダ発生
器を提供することにある。 The present invention has been made in view of the above circumstances, and its purpose is to provide a sodium hypochlorite generator that can suppress the decrease in the concentration of the stored solution as much as possible.

いる。[Means for Solving the Problems] In order to achieve the above object, the sodium hypochlorite generator of the present invention includes a generation tank that receives saline water, and a generation tank that is placed in the generation tank and electrolyzes the saline water. a pair of electrodes that generate sodium hypochlorite, a cooling means that is attached to the generation tank to cool the internal solution, a plurality of storage tanks that store the generated solution, and a storage tank that stores the solution from the generation tank. It consists of a first switching means that alternately sends the solution to the tank, and a second switching means that preferentially discharges the solution stored in the tank first.

る。[Operation] With these configurations, when a certain amount of saline water is first injected into the generation tank and the power is turned on, a current flows through the pair of electrodes and electrolysis of the saline water is started. During this time, the cooling means maintains the inside of the production tank below a certain temperature to prevent decomposition of the unstable sodium hypochlorite.

Next, the first switching means is actuated to send the produced solution to the storage tank opposite to the storage tank to which it was previously sent, and then the second switching means allows the solution in the tank where it is already stored to be discharged. .

A temperature sensor 40 is attached to the bottom surface of the generation tank 12. The compressor 24 and the blower 26 are controlled according to the liquid temperature.
以上のように構成された本実施例の次亜塩素酸
ソーダ発生器１０は、次のように作動する。 The sodium hypochlorite generator 10 of this embodiment configured as described above operates as follows.
まず、ケーシング上方の蓋２１を開けて食塩と

予め用意された食塩水１１を注入してもよい。 First, the lid 21 above the casing is opened, salt and fresh water are put into the generation tank 12, and after stirring well, the electrodes 13 and 14 are set and the lid 21 is closed. Alternatively, remove the plug 22 attached to the lid 21 and insert the lower end of the hopper (not shown) into the gas vent hole 21A,
A saline solution 11 prepared in advance may be injected.

も溶液を取出せるようになつている。 Further, in the standby state, the first three-way valve 30 is closed, and the saline solution 11 in the generation tank 12 does not flow into either of the storage tanks 32A, 32B. The second three-way valve 34 is connected to a storage tank 32 in which the solution is stored.
The B side (FIG. 1) is opened so that the solution can be taken out from the faucet 36 at any time.
次いで、タイマ１６を所定時間にセツトする

安定化された後に各電極１３，１４に送られ、食
塩水１１の電気分解が開始される。 Next, when the timer 16 is set to a predetermined time, the current from the power source is rectified and stabilized by the constant current device 15, and then sent to each electrode 13, 14, and electrolysis of the saline solution 11 is started.

Of these, hydrogen gas flows out through the fine holes in the stopper 22, and since the mist cannot pass through the fine holes in the stopper 22, part of it adheres to the bottom surface of the stopper 22, and the rest is repelled and returned to the generation tank 12.

動に影響されることがない。 Further, when the temperature of the solution and the production tank 12 rises due to this exothermic reaction, the temperature sensor 40 detects this and the compressor 24 is activated. Therefore, the refrigerant circulates through the cooling tube 23 to cool the generation tank 12, and the concentration of the solution is gradually increased while suppressing decomposition of the sodium hypochlorite. Furthermore, even if a voltage drop occurs on the power supply side, the constant current device 15
Since a constant current, specifically a current of 17 to 18 A, is always supplied to 14, the electrolysis rate is not affected by fluctuations in the power supply voltage.
この実施例では、液温を15〜16℃に維持してお

As shown in the figure, an operation signal is sent from the controller 41 to the first three-way valve 30 and the second three-way valve 34, the first three-way valve 30 opens the pipe 31A side for a certain period of time, and the second three-way valve 34 opens the pipe 33B side. to open. Therefore, the solution in the storage tank 32B can be drained, and a newly produced solution is stored in the storage tank 32A, and when the user opens the faucet 36 (FIG. 3), the solution in the storage tank 32B flows into the pipe 33.
B, discharged through the second three-way valve 34 and pipe 35;

となり、使用によつて減少または空になつた貯蔵
タンク３２Ｂに新たな生成溶液が貯蔵される。 Next, when the second solution is generated in the generation tank 12 and the timer 16 expires, the first three-way valve 30 opens the pipe 31B side for a certain period of time, and the second three-way valve 34
opens the pipe 33A side. Therefore, the previously stored solution in the storage tank 32A can be discharged, and a new produced solution is stored in the storage tank 32B, which has decreased or become empty due to use.

より抑えられる。 Since the previously stored solution is preferentially released, there is no possibility that a part of the solution will remain for a long time and its concentration will drop significantly, or that a new solution will not be mixed into a low concentration solution. In addition, the cooling tube 42 and the heat insulating material 4
3 keeps the storage solutions in the storage tanks 32A and 32B below a certain temperature, so decomposition of sodium hypochlorite is further suppressed.

A pair of electrodes for generating soda, a cooling means attached to the generation tank for cooling the internal solution, a plurality of tanks for storing the generated solution, and a second tank for alternately sending the solution from the generation tank to each storage tank. The storage tank is composed of a first switching means and a second switching means that preferentially discharges the solution in the tank that is stored first, and the old solution is discharged first and the new solution is sent to another storage tank. This has the effect of suppressing a decrease in the concentration of the entire storage solution.
