The attachment portion 12 of the ozone gas treatment unit 6 is configured to be attached to the protrusion portion 8 of the container 2 so as to be positioned outside the protrusion portion 8 of the container 2 (so that the protrusion portion 8 of the container 2 is fitted). The

  The ozone gas treatment unit 6 of the ozone water generator 1 is configured such that the attachment portion 12 is fixed to the protruding portion 8 of the container 2 and attached to the container 2. For example, the ozone gas processing unit 6 has a thread or a groove formed on the outer surface of the protruding portion 8 of the container 2 and the inner surface of the mounting portion 12 of the ozone gas processing unit 6. It is configured to be fixed by being screwed to the two protruding portions 8 and attached to the container 2.

  The ozone gas processing unit 6 of the ozone water generating apparatus 1 is configured such that the ozone decomposition catalyst 10, the exhaust fan 11, and the hood 13 are placed above the attachment portion 12. The ozone gas processing unit 6 is configured by arranging the ozone decomposition catalyst 10 so as to cross the attachment portion 12 in a plan view. The ozone gas processing unit 6 includes an exhaust fan 11 covered with a hood 13, and the exhaust fan 11 and the hood 13 are disposed above the ozone decomposition catalyst 10. The ozone gas treatment unit 6 is configured so that a predetermined space (gap) is formed between the ozone decomposition catalyst 10 (and the exhaust fan 11) and the inner surface of the mounting portion 12 (the upper edge inside the mounting portion 12). A decomposition catalyst 10 and an exhaust fan 11 are arranged.

  The ozone gas processing unit 6 of the ozone water generator 1 operates the exhaust fan 11 to negatively pressure the inside of the container 2 (a predetermined space between the surface of the ozone water stored in the container 2 and the lid member 20). The ozone gas in the container 2 (the ozone gas present in the predetermined space that is not dissolved in the raw water or ozone water in the container 2) is sucked by the exhaust fan 11 and decomposed into oxygen by the ozone decomposition catalyst 10 to It is comprised so that it may exhaust out of the container 2 from the opening part 9 (refer FIG. 3).

  The introduction port 7 of the ozone water generating device 1 is the fresh air circulation port when fresh air (gas outside the container 2) is introduced from the outside of the container 2 into the container 2. The ozone gas processing unit 6 of the ozone water generating device 1 is disposed above the opening 9 of the container 2 so that the introduction port 7 is formed. In the ozone water generating apparatus 1, a predetermined space (gap) is formed between the ozone decomposition catalyst 10 (and the exhaust fan 11) of the ozone gas processing unit 6 and the inner surface of the mounting portion 12. In the state of being disposed above the opening 9 of the two, a predetermined space (and the opening of the container 2) between the ozone decomposition catalyst 10 (and the exhaust fan 11) of the ozone gas treatment unit 6 and the inner surface of the mounting portion 12. 9), the outside of the container 2 and the inside of the container 2 communicate with each other. In the ozone water generating device 1, a predetermined space between the ozone decomposition catalyst 10 (and the exhaust fan 11) of the ozone gas processing unit 6 and the inner surface of the mounting portion 12 is configured as an inlet 7 of the ozone water generating device 1. The The ozone water generator 1 is configured to draw the ozone water that is not dissolved in the raw water or ozone water in the container 2 by the exhaust fan 11 of the ozone gas processing unit 6. A predetermined space) between the lid member 20 and the lid member 20 becomes a negative pressure, and fresh air (gas outside the container 2) is introduced from the outside of the container 2 into the container 2 through the introduction port 7. (See FIG. 3).

  As described above, the ozone decomposition catalyst 10 and the exhaust fan 11 are provided, and the ozone gas that is disposed in the opening 9 of the container 2 and is not dissolved in the raw water or ozone water in the container 2 is sucked by the exhaust fan 11 and ozonolysis is performed. In the ozone water generating apparatus 1 including the ozone gas treatment unit 6 configured to be decomposed into oxygen by the catalyst 10 and exhausted from the opening 9 of the container 2, ozone gas that is not dissolved in the raw water in the container 2 is decomposed into oxygen. Then, the air is exhausted from the opening 9 of the container 2 to the outside of the container 2. Therefore, according to the ozone water production | generation apparatus 1, it can prevent that ozone gas leaks from the container 2, without making the container 2 into a highly airtight structure (with a simple structure).

  The opening 9 of the container 2 of the ozone water generator 1 is configured as an inlet for injecting raw water into the container 2. Thus, in the ozone water generating apparatus 1 in which the opening 9 of the container 2 is configured as an inlet for injecting raw water into the container 2, the ozone gas treatment unit 6 is disposed at the inlet (opening 9) of the container 2. In this way, the one that can prevent the ozone gas from leaking from the container 2 is configured. Therefore, according to the ozone water production | generation apparatus 1, what can prevent that ozone gas leaks from the container 2 is easily realizable. Moreover, according to the ozone water production | generation apparatus 1, since the ozone gas processing unit 6 is arrange | positioned at the inlet (opening part 9) of the container 2, and what can prevent that ozone gas leaks from the container 2 is comprised. The ozone water generator 1 can also be configured using a general-purpose container (container 2) having an inlet (without using a dedicated container).

  In the ozone water generating apparatus 1, when a general-purpose container (container 2) that can be attached with a cap and can cover the injection port (opening 9) is used, the specifications for attaching the ozone gas treatment unit 6 to the container 2 are as follows. The cap can be attached to the general-purpose container (container 2) in the same manner as described above. For example, if the cap specification for the general-purpose container (container 2) is such that the cap is screwed into the protruding portion 8 and the inlet is covered, the mounting portion 12 of the ozone gas treatment unit 6 is the same. The ozone gas treatment unit 6 is attached to the container 2 by screwing into the protrusion 8. Thus, in the ozone water generating apparatus 1, the mounting specification of the mounting portion 12 of the ozone gas processing unit 6 to the protruding portion 8 of the container 2 is the same as the mounting specification of the cap to the inlet of the general-purpose container (container 2). Thus, the state in which the ozone gas treatment unit 6 is attached to the protruding portion 8 of the container 2 is changed to a state in which a cap is attached to the protruding portion 8 of the container 2 (a state in which the opening 9 of the container 2 is covered). Work can be done easily. Further, in this manner, in the ozone water generating apparatus 1, the mounting specification of the mounting portion 12 of the ozone gas processing unit 6 to the protruding portion 8 of the container 2 is the same as the mounting specification of the cap to the inlet of the general-purpose container (container 2). By doing, what can fix and attach the ozone gas processing unit 6 to the container 2 is realizable with a simple structure.

  The introduction port 7 of the ozone water generator 1 is configured such that the supply device 5 (the other end of the supply pipe 4) can be disposed in the container 2 through the introduction port 7. As described above, in the ozone water generating apparatus 1, since the introduction port 7 is configured so that the supply device 5 can be disposed in the container 2 through the introduction port 7, the ozone gas treatment unit 6 is supplied in a state of being disposed in the container 2. The container 5 can be disposed in the container 2, and the supply device 5 can be easily disposed in the container 2.

  In the ozone water generator 1, the ozone gas generator 3 can be attached to the container 2 (the protruding portion 8 of the container 2) together with the ozone gas processing unit 6. At this time, the ozone gas generator 3 is disposed above the opening 9 of the container 2 (see FIG. 4). Thus, the ozone gas generation device 3 is attached to the container 2 (the protruding portion 8 of the container 2) together with the ozone gas processing unit 6, whereby the overall configuration of the ozone water generation device 1 can be made compact.
