BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spraying device capable of spraying strong bactericidal electrolyzed water (acidic water or alkaline reduced water) produced by electrolyzing tap water.

[0002]

2. Description of the Related Art Due to the nature of business, strict hygiene control is required for employees in food manufacturing factories, restaurants, restaurants, hospitals, etc. that handle food, and to prevent contamination by bacteria. To do this, employees are washing hands and sterilizing and disinfecting equipment. As the sterilization method, a sterilization method by boiling or a method using chemical agents such as sodium hypochlorite, alcohol, ozone, etc. has been conventionally adopted depending on its use. Among these, it is pointed out that the sterilization method using chemicals can be easily used, but it is dangerous if it is mishandled, and it is also harmful from the viewpoint of employee health management. .

Recently, in order to eliminate such a harmful effect, a disinfection method using electrolyzed water produced by electrolyzing tap water has attracted attention (for example, Japanese Patent Laid-Open No. 1-3175).
No. 90). As shown in FIG. 3, this electrolyzed water generator includes a container 100 of an electrolyzer and an outlet 1 for alkaline reduced water.
02 and an outlet 104 for oxidizing water, and the inside of the alkaline reducing water chamber 1 is formed by a diaphragm 106 made of an ion exchange resin.
08 and the oxidizing water chamber 110. The alkaline reducing water chamber 108 and the oxidizing water chamber 110 are provided with a cathode 112 and an anode 113, respectively.
A DC power supply 114 is connected to 113. Container 10
When tap water is supplied to the inside of 0, the tap water is separated into alkaline reduced water and oxidized water while flowing toward the alkaline reduced water outlet 102 and the oxidized water outlet 104. The electrolyzed water thus generated has a bactericidal action, and if it is used for cleaning a cutting board or a cloth, it can be odord or disinfected.

[Problems to be Solved by the Invention] With such electrolyzed water,
For example, to sterilize human fingers, store electrolytic water in the tank in advance and wash the hand by opening the faucet and discharging water, or store the electrolytic water in a washbasin in advance and wash hands. It is possible to

However, in the former method of discharging the electrolyzed water stored in the tank from the faucet, a large amount of electrolyzed water is consumed each time the hand washing is performed, and the electrolyzed water is wastefully used. There were challenges. On the other hand, in the latter method of storing electrolyzed water in the washbasin, although electrolyzed water can be used relatively efficiently, it can be used by multiple people or exposed to an atmosphere such as air or light rays. Therefore, it was not possible to know when the electrolyzed water stored in the washbasin had no sterilizing ability because the sterilizing ability decreased with time. Therefore, in consideration of safety, the electrolyzed water in the washbasin must be replaced with a new one as soon as possible, and the electrolyzed water could not be used efficiently as in the former case.

The present invention has been made in order to solve such a problem, and sterilizes the electrolyzed water that can be used efficiently by ejecting the electrolyzed water contained in the container in a mist form. An object of the present invention is to provide a spraying device for electrolytic water.

[0007]

According to the present invention, there is provided a container for containing electrolyzed water for sterilization, a water guiding pipe for guiding the electrolyzed water in the container to a spray port, and a device for applying a pressure to the electrolyzed water in the container. It is characterized by comprising a pressure means and a spray nozzle which is connected to the spray port and sprays electrolyzed water in a mist state. Further, the container is a light-tight closed container.

[0008]

If the above means is adopted, the electrolyzed water having sterilizing ability is sprayed to the outside of the container by the pressing means.
By using a small amount of electrolyzed water, it becomes possible to efficiently sterilize the object to be sterilized over a wide range.
In addition, since the electrolytic water is isolated from the atmosphere such as air and light rays by using a light-tight closed container as a container for storing the electrolyzed water, it is possible to suppress the deterioration of the sterilization ability of the electrolyzed water over time and to perform electrolysis. Allows long-term storage of water.

The controller 34 starts / stops the spraying of oxidizing water.
Is controlled by detecting the states of the foot switch 36, the float switch 38 in the water supply tank 10, and the float switch 40 in the drain tank 24.
That is, spraying of the oxidizing water is started by pressing the foot switch 36. At this time, when the float switch 38 detects that the water supply tank 10 is empty, or when the float switch 40 detects that the drainage tank 24 is full, the foot switch 38 Even if 36 is pressed, the water discharge pump 14 is not driven and the oxidizing water is not sprayed. As a result, the water tank 1
When the water discharge pump 14 is driven when 0 is empty, the water discharge pump 14 is prevented from being damaged, and the drain tank 24
When the water is full, the discharge pump 14 is driven to prevent the overflow of the drainage tank 24 by spraying the oxidizing water.

When the drain tank 24 is full, the tank valve 42 is opened and the drain pump 44 is driven to drain the drain tank 24. The pressure switch 46 detects the water pressure on the water inlet side of the drainage pump 44, and when the pressure switch 46 detects the completion of drainage, the tank valve 4
2 is closed and the drive of the drainage pump 44 is stopped. As a result, the pump 4 by idling the drainage pump 44
