[0002]

2. Description of the Related Art At present, this kind of sterilizer has a
As for disinfection, chemical treatment is the mainstream,
Among them, low-cost liquid chlorine and sodium hypochlorite are used. In addition, it is certified as a food injection,
Chlorinated isosialic acid, which is stable and easy to transport and store, is also used as a highly bleached powder or solid chlorine agent.

[0003] However, while the sterilizing / antibacterial apparatus is low in cost and excellent in simplicity of the sterilizing process, it may cause environmental problems in the safety of the medicine itself to human bodies and wastewater treatment.

[0004] In order to solve such problems, a sterilizing apparatus using an electric sterilizing process has been developed. This sterilizing apparatus is to supply an appropriate electric current to water and obtain sterilized water by an electrolysis. In some cases, auxiliary liquids that promote electrolytic action are added due to subtle differences in the method of generating sterilizing water, but since chemicals that affect water quality are basically unnecessary, various problems caused by chemical input are solved. Have been.

[0005]

However, in this disinfecting apparatus, hypochlorous acid, which is a main component having a disinfecting effect, is volatile and thus has a poor sustaining effect. New problems such as the need for a large amount of sterilizing water and the increase in the size of the drainage system have arisen because the reaction takes time to reduce the hypochlorous acid concentration.

[0006] In addition, sterilization treatment with ozone water is also performed, but this method has an ozone half-life in water of several tens of minutes, has a poor sustaining effect of one hour or more, and gives ozone itself to human bodies and foods. There were problems such as unclear effects, and the use was limited.

An object of the present invention is to provide a sterilizing / antibacterial device which is safe and inexpensive, does not cause environmental problems in wastewater treatment and the like, and has a long lasting effect.

Since this natural disinfectant / antibacterial agent keeps its antibacterial action, it can surely kill or inhibit the growth of microorganisms and the like that are breeding in foodstuffs, and also have an effect on the environment when discharging the treated water. I will not give.

[0010] As a structure for injecting the natural disinfectant / antibacterial agent, in the invention of claim 2, it is injected into the water supply piping system by a pump means, and in the invention of claim 3, it is injected into the water supply piping system under natural flow. In the invention, a structure in which the water is injected into a water supply piping system by a suction device is adopted.

In addition, as means for adjusting the amount of the natural disinfectant / antibacterial agent to be injected into the raw water, the invention according to claim 5 adjusts the amount by a flow rate adjusting means, and claim 6 adjusts the driving time of the pump means by a timer. In the invention of claim 7, the opening time of the on-off valve is adjusted by a timer.

According to the invention of claim 8, the storage tank storing the natural sterilizing / antibacterial agent is directly connected to a terminal such as a faucet, and the terminal is mixed with the natural sterilizing / antibacterial agent in the raw water.

According to the ninth aspect of the present invention, since a raw water purifying device is installed in the water supply piping system, microorganisms floating in the raw water are removed in advance by the purifying device, and the sterilizing / antibacterial effect is improved.

According to a tenth aspect of the present invention, purified water not containing a natural sterilizing / antibacterial agent is supplied from the first water supply line.
Raw water containing a natural disinfectant / antibacterial agent is supplied from the second water supply line. In this way, when purified water suitable for drinking is desired, water may be obtained from the first water supply line, and when water suitable for sterilization of foodstuffs, etc., water is required from the second water supply line. Just get it.
