2. Description of the Related Art A method and a device for supplying a gaseous or mist-like disinfectant to a room or a container to disinfect articles contained in the room or the container are known.
Japanese Patent No. 64174 discloses that an antiseptic solution is sprayed into a closed room and left for a predetermined time, and then the sprayed antiseptic solution is coagulated and removed.
Next, a room disinfection method for spraying a neutralizing solution into a room to neutralize and remove the remaining disinfecting solution, and finally coagulating and removing the unreacted neutralizing solution, and an apparatus used for the method have been proposed.

[0003] The disinfecting method using such a gaseous or mist disinfectant is characterized in that it does not wet the material to be disinfected, so that it is possible to easily disinfect all kinds of objects. That is, for example, in the case of disinfecting footwear, the footwear to be disinfected is stored in a disinfecting box (clog box) having a sealable opening / closing door, and the opening / closing door is closed, and a gaseous or mist-like state is placed in the disinfecting box. By supplying the disinfectant and leaving it for a certain period of time, the stored footwear can be disinfected.

[0004]

However, in the above disinfection method, it is necessary to expose the entire surface of the material to be disinfected to a gaseous or mist-like disinfectant. It happens that it cannot be disinfected. For example, in the case of disinfecting footwear, when footwear is stacked and stored in a disinfecting box, the parts in contact with each other are not exposed to the disinfectant, so that the parts are sufficiently disinfected. It cannot be obtained and cannot be completely disinfected. Therefore, the footwear to be disinfected is placed on the mounting plate (bottom plate or shelf plate) of the disinfecting box to perform disinfection. However, even in this method, the bottom surface of the footwear in contact with the mounting plate is used. Will remain undisinfected.

According to the present invention, the entire surface of a disinfectant is completely disinfected by bringing the disinfectant contained in the disinfection box into full contact with the gaseous or mist disinfectant supplied to the disinfection box. It is an object of the present invention to obtain a disinfecting box that has a simple structure and does not require replacement of a disinfectant during disinfection.

[0006]

The structure according to the present invention comprises a sealable opening / closing door 2, and supplies a gaseous or mist-like disinfectant to an internal space to disinfect a disinfectant contained in the space. To be used in disinfection boxes.

In the disinfecting box according to the first aspect, the mounting plate 4 on which the material to be disinfected is mounted has an upper plate 6 having a large number of through holes 5 and a lower plate 7 having a projection 7 penetrated from below through the through holes.

The disinfecting box according to the second aspect of the present invention includes the mounting plate 4 on which the object to be disinfected is mounted, the upper plate 6 having a plurality of through-grooves 20, and the ridge 17 penetrating through the through-grooves from below. Elevating devices 10, 11, 12, 13 are formed by the lower plate 8 and move the upper and lower plates relative to each other.

[0009] A stepping motor can be used as a drive source of the elevating device of these disinfecting boxes, and a timer for setting a time interval for intermittently rotating the stepping motor is provided, so that the upper plate and the lower plate during disinfection are provided. The relative elevation of the plate can be automated.

As the upper plate having the through-holes 5, a wire mesh, an expanded metal, or the like can be used, as well as a plate material provided with a number of small holes generally called a punching metal. As the lower plate, it is convenient to use a synthetic resin molded plate in which the projections 7 are formed in the through holes of the upper plate. As the upper plate having the through groove 20, a pipe having a structure in which a plurality of pipe materials are arranged in parallel can be used, and the lower plate can be a synthetic resin plate integrally formed with a ridge or a plurality of pipes which can pass through the above described through groove. It is possible to adopt a structure in which the pipe members are arranged in parallel.

The relative lifting device is a device for lifting one of the upper plate and the lower plate with respect to the other. When a plurality of mounting plates for disinfectants are provided, a relative elevating device may be provided for each stage, but the upper plate or lower plate of each stage is connected by a vertical rod or a hanging string. It is convenient to move up and down all at once.
As a drive source of the relative lifting device, a device driven by electric force is practical, and a solenoid, an electric cylinder, or the like can be used in addition to a motor. When a motor is used, the rotation of the motor is converted into a vertical movement by a cam, a link, a screw mechanism, or the like. When a solenoid is used, a detent mechanism is provided so that the elevation position is switched every time one or more solenoids operate. Relative lifting and lowering movements
It may be repeated one or more times, and the operation time interval is conveniently set by a timer.

In the disinfecting box having the above structure, the object to be disinfected stored in the box mounted on the mounting plate, when supported by the upper plate 6, has its through hole 5 or through groove 20 formed therein. When the provided portion is exposed to the disinfectant and the upper plate and the lower plate move up and down relative to each other and the object to be disinfected is supported by the lower plate 8, the portion provided with the through hole 5 or the through groove 20 is provided. Since the other parts are in contact with the disinfectant, there are no parts that cannot be disinfected by contact with the mounting plate.

[0013]

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 is a perspective view showing the internal structure of the disinfecting box, and the box body 1 and the opening / closing door 2 are shown by imaginary lines. Box body 1
Is made of, for example, an iron plate, and is provided with a circular supply port 3 for supplying a gaseous or mist-like disinfectant on one side surface thereof. The opening / closing door 2 is a double door, and a sealing material for hermetically sealing the container is provided on the peripheral edge thereof.

The disinfecting box shown in the figure is provided with three stages of mounting plates 4, and the mounting plates of each stage are, as shown in detail in FIG.
An upper plate 6 having a number of through holes 5 formed therein and a lower plate 8 integrally formed with a projection 7 inserted from below with a sufficient play space in the through holes of the upper plate. The upper plate 6 is provided with both sides and a back side fixed to the box body 1. At four corners of the upper plate 6, through holes 9 larger in diameter than the through holes 5 are provided.

The three lower plates 8 are connected by rods 10 fixed to their four corners at the same vertical interval as the upper plate, and move up and down integrally. The rod 10 passes through the through hole 9 in the upper plate.

Immediately below the uppermost lower plate 8, a shaft 11 is mounted on the box main body 1 along the lower front side and the lower rear side so that both ends are rotatably supported. Cams 12 are fixed near both ends of the shaft, and one end of each shaft is connected to a stepping motor 13 that is driven synchronously and intermittently. The same drive pulse is supplied from the controller 14 to the two stepping motors. At the time intervals set by the timer provided in the controller 14, the same number of drive pulses as to rotate the shaft 11 half a turn are applied. You.

The lower plate 8 of the uppermost mounting plate has four corners supported by cams 12. When the cam 12 faces downward and the lower plate 8 is at the lowered position, the projections 7 of the lower plate are located below the upper surface of the upper plate 6. Therefore, the disinfectant placed on the mounting plate 4 is supported by the upper plate 6.
In this state, the gaseous or mist-like disinfectant supplied into the box passes through the through hole 5 and contacts the bottom surface of the disinfectant.

After disinfecting for a predetermined time in the above state, when the stepping motor 13 is rotated half a turn, the cam 12 faces upward and the lower plate 8 of the mounting plate 4 is raised. In this state, the projections 7 of the lower plate protrude from the upper surface of the upper plate 6 and the disinfectant is supported by the projections 7 of the lower plate. In this state, portions other than the portion supported by the projections 7 on the bottom surface of the disinfectant contact the gaseous or mist disinfectant.

Therefore, by raising and lowering the lower plate 8 once or a plurality of times at a predetermined time interval during a predetermined disinfection time, the entire surface of the material to be disinfected comes into contact with the disinfectant, and the undisinfectable portion is eliminated.

FIG. 3 is a view showing another example of the mounting plate.
In the example of FIG. 3, the upper plate 6 is composed of a plurality of metal pipes (upper pipes) arranged parallel to the width direction (longitudinal direction) of the disinfecting box.
15. Both ends of the plurality of upper pipes 15 are arranged in a direction perpendicular to the axis of the pipe, and
Is fixed to an upper bracket 16 which is in contact with the upper end of the peripheral surface of the box, and the upper bracket is fixed to the box body 1. On the other hand, the lower plate 8 is formed by arranging a plurality of metal pipes (lower pipes) 17 having a larger diameter than the upper pipe 15 (one less than the number of upper pipes) in parallel. 17 are integrally connected by a lower bracket 18 which abuts the lower end of the peripheral surface at both ends. The arrangement interval between the upper pipe 15 and the lower pipe 17 is an interval at which a gap 20 wider than the diameter of the lower pipe 17 is formed between the upper pipes 15.

In the above structure, the lower bracket 1 is held until the lower bracket 18 contacts the lower end of the peripheral surface of the upper pipe 15.
When 8 is moved upward, the upper end of the peripheral surface of the lower pipe 17 protrudes above the upper end of the peripheral surface of the upper pipe 15 due to the difference in the diameter of the metal pipe.

The lower plates 8 of a plurality of steps are connected by a cable 19 fastened to both ends of the metal pipes at the front end and the rear end, and the cable 19 passes through a gap 20 between the upper pipes.

The mounting plate having the above structure can be relatively moved up and down by a relative lifting device similar to that shown in FIG. 1. When the lower plate 8 moves down, the material to be disinfected is supported by the upper pipe 15, When the lower plate 8 is moved upward, it is supported by the lower pipe 17, so if the lower plate is raised and lowered once or more times during a predetermined disinfection time, the disinfectant comes into contact with the mounting plate. Position is changed, and the bottom surface of the disinfectant contacts the disinfectant evenly.
