Air is blown out from the bed 30 and blows off the dust attached to the bed 30. This blown dust is adsorbed by the filter 13, and the cleaned air in the sterilization chamber 5 is again sent from the blower 11 to the communication pipe 12, and the dust removal work is carried out while the air in the sterilization chamber 5 is circulated. It will be done. When the dust removal work is completed after a predetermined period of time has elapsed, each ultraviolet lamp 16a, 16b,
16c, 16d, 16e light up, bed 30
Ultraviolet rays are irradiated towards the area to perform ultraviolet sterilization. When this ultraviolet sterilization work is completed after a predetermined period of time has passed, the blower 11 is operated again, and air is sent to the air supply pipe 17 this time, while the disinfectant solution is supplied from the supply pipe 20 and the spray device 1
Disinfection work is performed in which disinfectant is sprayed toward the bed 30 from the spray nozzle 21 of 8. When this disinfection work is completed after a predetermined period of time has elapsed, all the work of the standard course is completed.

The series of operations described above are automatically controlled by a microcomputer built into a control section (not shown). On the other hand, the ultraviolet course is the standard course mentioned above that excludes disinfection work, and the disinfection course is the standard course mentioned above that excludes the ultraviolet sterilization work. is as described above, so its explanation will be omitted.

In the sterilizer after the work is completed, when the closing sheet 28 is opened and the frame body 5g is moved in the direction of the main body 1 by grasping the handle 29, each of the frame bodies 5g, 5f, 5
e, 5d, 5c, and 5b move sequentially while overlapping each other, are housed inside the main body 1 from the open part, and overlap with the frame 5a. At this time, since the ventilation duct 14 is expandable and flexible, it contracts like a bellows, and each frame body 5g, 5f, 5e, 5d, 5c,
Does not inhibit the movement of 5b. In addition, each support 6a, 6
b, 6c, 6d, and 6e, each frame 5
g, 5f, 5e, 5d, 5c, 5b, 5a are shifted and overlapped, and each ultraviolet lamp 16a, 1
The space for 6b, 16c, 16d, and 16e is secured and they will not be damaged. Here, when the lift switch of the control section (not shown) is turned on, the lifting device 23 is operated and the forks 26 are raised, and each of the frames 5a, 5b, 5 in the contracted state is
c, 5d, 5e, 5f, and 5g rise, and their lower ends are separated from the floor (see Figure 2).
In this state, while the bed 30 is returned to the predetermined position, the sterilizer is moved again to the next sterilization work position or storage position.

It should be noted that the present invention is not limited to the embodiments described above, and it goes without saying that many modifications can be made without departing from the technical idea thereof.

Effects As explained above, according to the present invention, the sterilization chamber in a contracted state can be moved up and down, so the main body can be moved with the lower end of the sterilization chamber separated from the floor. , it is possible to achieve the effect that the main body can be easily and smoothly moved.
