Embodiments of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 to 3 show a first embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a bottomed box-shaped collection container which is opened at the top and into which filth such as a diaper (not shown) is put. An inlet 2 is formed. In addition, rotatable casters 3 are rotatably supported at four corners of the bottom surface of the collection container 1, and the collection container 1 is configured to be movable. Reference numeral 4 denotes a lid which opens and closes the inlet 2, is formed in a box shape with an open lower surface, and is pivotally connected to one end edge of the collection container 1 by a hinge 5. Two sets of ozone tubes 6 formed in a U-shape are attached to the back side of the lid 4, and a number of rotating blades are provided on the periphery near one end of the lid 4 adjacent to the two ozone tubes 6. A sirocco-type blower fan 9 having a fan 8 is provided. The ozone tube 6 is attached and fixed to a heat-insulating base plate 7 fixed to the back side of the lid 4.
A partition plate 10 that covers the blower fan 9 is formed on the back side of the lid 4. The partition plate 10 is formed so as to be curved downward as the distance from the ozone tube 6 increases, and the intake port 11 and the exhaust port are formed at both end edges of the partition plate 10.
12 and open. In this embodiment, an intake port 11 is opened facing the ozone pipe 6, and an exhaust port 12 is opened facing the input port 2 of the collection container 1. Reference numeral 15 denotes a limit switch for detecting the lid 4, which is fixed to a mounting plate 17 fixed to the inside of the collection container 1 so as to face the inlet 2. The lid 4 is provided with a receiving piece 18 which engages with the actuator 16 of the limit switch 15. When the lid 4 is opened, the receiving piece 18 formed on the lid 4 starts to move from the receiving piece 18 to the limit switch 15.
The 15 operating elements 16 are separated, and the operating elements 16 are returned by a spring (not shown) and turned off, thereby shutting off the power supply to the ozone tube 6.

The operation of the present embodiment configured as described above will be described.

First, when the lid 4 is opened and a waste such as a diaper is stored in the collection container 1 and the apparatus is started, the blower fan 9 is rotated by a motor (not shown).
The ozone tube 6 operates. Then, a part of oxygen in the air is changed to ozone by ultraviolet rays emitted from the ozone tube 6 by energizing the ozone tube 6, and the ozone generated in the ozone tube 6 is divided by the partition plate 10 by the blower fan 9. The air is blown into the collection container 1 from the exhaust port 11 through the space 10A. In this way, ozone circulates inside the collection container 1, and the diaper housed inside the collection container 1 is sterilized and purified by the ozone circulating inside the collection container 1, and the odor of the diaper is also reduced by the deodorizing effect of ozone. It is deodorized. In addition, when the diaper in the collection container 1 is taken in and out, when the lid 4 is opened, the actuator 16 of the limit switch 15 which engages with the lid 4 is returned by a spring (not shown), and ozone for sterilizing and deodorizing the diaper. The operation of the ozone tube 6 is stopped because the power supply to the tube 6 is cut off. That is, although ozone is excellent in sterilizing and deodorizing effects, inhaling excess ozone may adversely affect the respiratory organs. There is no need to worry about inhaling high concentrations of ozone and it is safe. Further, since the casters 3 are provided at the bottom of the collection container 1, the collection container 1 can be easily moved.

As described above, in the present embodiment, for example, filth such as a diaper stored in the collection container 1 is sterilized and deodorized with ozone generated by the ozone pipe 6 provided in the collection container 1. Since the ozone generated in the pipe 6 is circulated inside the collection container 1 by the blower fan 9, Escherichia coli and the like generated in the diaper and the like stored in the collection container 1 can be efficiently sterilized, so that propagation of various bacteria can be prevented. Also, the odor of the diaper can be prevented. Therefore, diapers and the like can be collected and stored in a sanitary manner, and in particular, by installing them in hospitals and the like, diapers for inpatients and other patients can be collected in a state of being sterilized in large quantities, and hospital infections are suppressed It is extremely hygienic and can also prevent the bad odor of used diapers by the deodorizing effect of ozone.

Further, when the cover 4 of the collection container 1 is opened by taking out the diaper or the like, the limit switch 15 for detecting the cover 4 is turned off, and the ozone tube 6 is automatically stopped. Ozone does not leak from the collection container 1 and is safe. Further, by forming the ozone tube 6 in a U-shape, the contact area between the ozone tube 6 and the air in the collection container 1 increases, so that ozone can be generated efficiently.

In the first embodiment, the case where the diaper is stored in the collection container 1 has been described. However, the present invention is not limited to the diaper.
For example, it may be installed at home to store garbage such as garbage and used for sterilizing and deodorizing garbage, and the use of the collection container 1 may be appropriately selected.

FIG. 4 shows a second embodiment of the present invention, in which parts having the same functions as those of the second embodiment are denoted by the same reference numerals, and a detailed description thereof will be omitted.

In the first embodiment, an example in which the upper surface of the collection container 1 is opened to form the input port 2 and the input port 2 is opened and closed by the rotatable lid 4 has been described. In the figure, the collection container 20 is formed in a box shape, and an input port 21 partially opened on the front side of the collection container 20 is provided. A lid 22 is pivotally supported on the inner surface of the collection container 20 by the hinge 5, and the opening 22 is opened and closed by the lid 22. Further, in the present embodiment, an outlet 23 for taking out dirt such as diapers contained in the recovery container 20 is formed on one side of the recovery container 20, and the outlet 23 is provided with an opening / closing door.
It opens and closes at 25. In the present embodiment, the collection container 20
A sensor 26 for detecting a human body by, for example, detecting infrared rays is provided on the front surface of the collection container 20. The sensor 26 outputs a detection signal when a person approaches the collection container 20 within a predetermined range. The power supply to the ozone tube 6 provided inside is cut off.

Therefore, in the present embodiment, when waste such as used diapers is thrown into the collection container 20 by pushing the lid 22 through the insertion opening 21 provided on the front surface of the collection container 20, Thereafter, the lid 22 is rotated downward by its own weight and the loading port 21 is closed, so that the diaper can be easily loaded into the collection container 20. Further, the diapers stored in the collection container 20 can be easily taken out from the outlet 23 by opening the opening / closing door 25. By circulating the ozone generated by the ozone pipe 6 with the blower fan 9 in the same manner as in the first embodiment, the diaper housed in the collection container 20 can be efficiently sterilized, and the diaper and the like can be disinfected. Bad odor can also be prevented.

When a person approaches the collection container 20 when the diaper is put into the collection container 20 or when the diaper in the collection container 20 is taken out from the outlet 23, the ozone tube 6 is turned on by a detection signal from the sensor 26. When the lid 22 or the opening / closing door 25 is opened and closed, the ozone of a high concentration does not leak out of the collection container 20 and is safe, because it is automatically stopped.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention. For example,
The shape of the collection container, the position of the input port or the opening / closing door, and the like may be appropriately selected. In addition, a lid for opening and closing the inlet and the outlet and a mounting structure of the door may be appropriately selected. Also,
In the second embodiment, a sensor for detecting infrared rays is exemplified as a sensor for detecting a human body, but a human body may be detected using an optical sensor or the like. Further, in the second embodiment, the lid and the opening / closing door may be respectively detected by the limit switches as in the first embodiment to control the ON / OFF of the ozone tube. Further, in each of the above embodiments, an intake port is formed facing the ozone pipe, an exhaust port is opened facing the input port of the collection container, and the ozone generated in the ozone pipe is sucked and sent to the collection container. Although an example in which ozone is circulated has been described, the ozone may be circulated by sucking air in the collection container and blowing it out to the ozone tube side.
