Description

  The present invention relates to a vaporizing humidifier with an improved drain pan mounting structure.

  The vaporizing humidifier humidifies the processing air by bringing it into contact with a humidifying module containing water for humidification. During the operation of the humidifier, humidification water is supplied to the humidification module, and the water in contact with the processing air flows down along the surface of the humidification module and is collected in a drain pan provided at the lower part of the humidifier. The water collected in the drain pan is discharged outside the humidifier by the drain pump.

  The humidification module needs to be cleaned or replaced due to the generation of scale due to water supply or the adhesion of dust in the air. Further, since residual water is accumulated inside the drain pan, microorganisms, algae, and the like may be generated, and it is necessary to remove the humidification module and the drain pan from the inside of the humidifier housing and periodically clean them. In particular, the ceiling-mounted vaporizer humidifier is installed at a high location from the floor of the building, so workers use a stepladder to remove the humidifier module and drain pan from the inside of the humidifier housing. It was difficult to remove and install the humidifying module and the drain pan. Therefore, what was described in patent documents 1 and patent documents 2 was proposed conventionally as a vaporization type humidifier which made easy attachment or detachment work of a humidification module and a drain pan.

JP 2012-57890 A Japanese Patent Laid-Open No. 10-288357

  In the conventional vaporizing humidifier, since the drain pan is screwed to the inside of the housing, if the screw is removed when the drain pan is removed, the drain pan will fall off the housing and fall. Therefore, one worker supported from the bottom so that the drain pan did not fall, and another worker loosened and removed the screw during that time. As described above, in the prior art, a plurality of workers are required to safely remove the drain pan.

  In particular, in a drain pan with a humidifying module that fixes the drain pan and the humidifying module together, it is necessary to remove the integrated drain pan and the humidifying module from the ceiling for inspection of the humidifying module and cleaning and maintenance of the drain pan. Since the weight of both is considerably large, it was difficult for one person to perform the removal work.

  The present invention has been proposed to solve the above-described problems of the prior art. An object of the present invention is to provide a vaporizing humidifier capable of easily and safely removing a drain pan from the inside of a housing even if the drain pan is heavy, such as a drain pan with a humidifying module.

The vaporizing humidifier of the present invention has the following configuration.
(1) A housing having a lower opening, a humidifying module provided inside the housing, a water supply device for the humidifying module, a blower for the humidifying module, and a drain pan for storing water flowing down from the humidifying module.
(2) Projections provided at both ends of the drain pan.
(3) Support members provided on the inner surfaces of the housing facing each other.
(4) A protrusion holder provided on the support member.
(5) Protrusion doorway provided in the lower part of the holder.
(6) A stopper that moves in a direction to open and close the entrance / exit of the protrusion.
(7) A screw for fixing the stopper in a position to close the projection entrance.
(8) A fall prevention member provided below the entrance / exit of the protrusion.
(9) A passing portion opened downward at one end of the fall prevention member.

A vaporizing humidifier having the following configuration is also an embodiment of the present invention.
(1) A housing having a lower opening, a humidifying module provided inside the housing, a water supply device for the humidifying module, a blower for the humidifying module, and a drain pan for storing water flowing down from the humidifying module.
(2) Support members provided at both ends of the drain pan.
(3) Projections provided on the inner surfaces of the housing facing each other.
(4) A protrusion holder provided on the support member.
(5) Protrusion entrance / exit provided on the upper part of the holder.
(6) A stopper that moves in a direction to open and close the entrance / exit of the protrusion.
(7) A screw for fixing the stopper in a position to close the projection entrance.
(8) A fall prevention member provided above the entrance / exit of the protrusion.
(9) A passing portion opened upward at one end of the fall prevention member.

According to the present invention, when the fixing screw is loosened and the stopper is moved, even if the drain pan falls due to its own weight, the drain pan does not fall any more because the protrusion and the fall prevention member are caught. Therefore, after removing the stopper on one side, it is possible to remove the stopper on the opposite side while the drain pan is hooked on the housing, and the stopper on the opposite side can be removed even if the drain pan is not supported. .
When both stoppers are removed, the protrusions on both sides of the drain pan and the fall prevention member are hooked, so the drain pan is moved horizontally to release the catch of the protrusion and fall prevention member and moved downward from the passage part. Thus, the drain pan can be removed downward from the housing.
As described above, according to the present invention, it is not necessary to remove the stoppers on both sides while supporting the drain pan from below, so that one operator can easily remove the drain pan.

The three protrusions 7 are accommodated in the holder 9 so that the upper ends thereof are substantially at the same positions as the upper ends of the three holders 9. At this time, the stopper 11 moves below each holder 9 and supports the protrusion 7 so as not to fall from the holder 9. The stopper 11 is fixed in the stopper groove 12 by tightening the head of the screw 15 and does not move.

  In order to remove the drain pan 6, first, on one side of the drain pan 6, the head of the screw 15 that fixes the stopper 11 to the support member 8 is loosened, and the screw 15 is pushed along the long groove 14 in the release direction, thereby stopping the stopper. 11 is moved in the release direction along the stopper groove 12. At this time, since the stopper 11 does not move only by loosening the screw 15, the drain pan 6 does not fall even if the drain pan 6 is not supported. Therefore, the work of loosening the screw 15 can be easily performed.

  After loosening the screw 15, the stopper 11 is moved while supporting the drain pan 6 with one hand from below. When the stopper 11 is moved from below the three holders 9, the entrance / exit 10 of the holder 9 opens, so that the projection 7 is lowered through the entrance / exit 10 as shown in FIG. 5. As shown in FIG. 6, the dropped projection 7 is caught by the fall prevention member 18 that is the lower side of the space portion 16, and the drain pan 6 does not fall any further.
