Description

  The present invention relates to a deodorizing and disinfecting spray apparatus for performing deodorizing and disinfecting by spraying stabilized chlorine dioxide in a mist form in a room such as a hospital operating room, a hospital room, a toilet, a waiting room, and a nursing facility.

  In recent years, outbreaks and infections of noroviruses and airborne bacteria have occurred in hospitals and nursing homes, and concerns about the hygiene of the facility have been observed not only for patients but also for doctors, nurses, and caregivers of nursing homes. Is growing.

Conventionally, as such a deodorizing and disinfecting apparatus in a facility room, a liquid effective for antibacterial, antifungal, deodorizing and the like is atomized by an ultrasonic vibrator like a conventionally known ultrasonic humidifier. A spraying apparatus for spraying indoors is known (see, for example, Patent Document 1).
However, in this patent document 1, as an effective liquid for deodorization and sterilization, for example, an aqueous solution in which an antibacterial effect, an antifungal effect, or a deodorizing effect such as a natural vegetable or organic composite agent is used alone or in combination is used. However, it is far from the level required in hospitals and other facilities.

The inventors of the present invention have devised a device for spraying chlorine dioxide using an ultrasonic vibrator, paying attention to the high deodorizing and sterilizing function of chlorine dioxide.
However, when atomizing with an ultrasonic transducer, if the amount of atomization is increased too much, the room gets wet. On the other hand, if the amount of atomization is small, the room will not get wet, but the sterilization effect will be weakened.

As a result of intensive studies, it has been found that atomization and wetting are related to the size of fog particles. The mist particles sprayed in the air eventually evaporate and disappear, but if the particle size is large, it is difficult to evaporate and wets the room. Although it is possible to reduce the particle size by adjusting the frequency of the ultrasonic vibrator, etc., there are actually particles that stick together and grow until they are blown out after atomization, so they are not uniform. .

  Stabilized chlorine dioxide is, for example, an aqueous solution containing a chlorite such as sodium chlorite and stabilized by adding a buffer, or chlorine dioxide gas is converted to an aqueous sodium carbonate solution. Many products such as those dissolved and stabilized are commercially available. In either case, chlorine dioxide gas is gradually released, and an acidic substance is added to lower the pH, or when activated by irradiation with ultraviolet rays, the amount of released chlorine dioxide gas increases. Although it does not specifically limit an ingredient, for example, TA-500 (trade name) (chlorine dioxide concentration; 5% (50,000 ppm)) of Takasugi Pharmaceutical Co., Ltd., TA-40 (trade name) (chlorine dioxide concentration) 4000 ppm) is available.

  The apparatus main body 10 is a rectangular parallelepiped box, and the liquid storage tank 20, the accumulator unit 40, and the ventilation path 50 are provided in series in the vertical direction from the bottom to the top, and a horizontal partition between the accumulator part 40 and the ventilation path 50 is provided. 11. Further, a tank storage section 12 in which a supply tank 90 which is a supply container for supplying a chlorine dioxide aqueous solution is removably stored in parallel with these three components is provided.

  The baffle plate 80 is provided in the ventilation path entrance 51 from the accumulator section 40 to the ventilation path 50. In this embodiment, the baffle plate 80 is formed by a plate member that is provided on the accumulator side of the ventilation passage entrance 51 and is inclined at a predetermined angle with respect to the vertical. In the illustrated example, the plate member has a quadrangular shape, and the upper end is fixed to the periphery of the ventilation path entrance 51 and is inclined downward toward the ventilation path entrance 51 side.

In the illustrated example, a plurality of baffle plates 80 are arranged in series in the direction of the air flow, and two in the illustrated example. The baffle plates 80 are connected to each other by a rod-like connecting member. ,

Next, the operation of the deodorizing and disinfecting and spraying apparatus of this embodiment will be described.
The stabilized chlorine dioxide aqueous solution L is atomized by the atomizing unit 30, and the fog particles accumulate in the accumulator unit 40 and ride on the air flow generated by the rotation of the blower 70, and are transferred from the accumulator unit to the lid body 16 through the ventilation path 50. It sprays from the blowing outlet 60 of the provided blowing nozzle 61. The sprayed mist particles of the stabilized chlorine dioxide aqueous solution evaporate and the chlorine dioxide gas is diffused into the room.

The fog particles come into contact with the baffle plate 80 when moving inside the apparatus main body 20 by riding on an air current. Among the fog particles that have come into contact with the baffle plate 80, relatively large particles adhere to the baffle plate 80, light relatively small particles ride on the airflow and move to the outlet, and relatively fine particles ride on the airflow and blow out.
