Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a nozzle pipe mounting structure for a commercial humidifier used in the textile industry.

Prior art humidifiers draw in dry air from the bottom of the device,
The air is humidified by forcibly passing it through the water supply filter containing water from the bottom to the top, and the high-humidity air is blown from the top of the device to the outside. Since the water contained in the water supply filter is consumed in a short time unless continuously supplied, a water circulation system for supplying water to the water supply filter is incorporated inside the humidifier.

The water circulation system in the humidifier sprays a large amount of water from above the water supply filter, collects the water dropped through the water supply filter in the storage chamber, and again the water in the storage chamber above the water supply filter via the circulation pump. It is sent back.
Since it is necessary to uniformly spray the water on the water supply filter so that there is no unevenness of spraying, a nozzle pipe with a fine water spray nozzle having excellent water diffusibility is used.
This nozzle pipe is permanently installed in the water circulation system. Further, the dried air is taken in between the lower surface of the water supply filter and the water surface of the circulating water accumulated in the storage chamber.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to such a conventional technique, the sprinkling nozzles are clogged with the operation of the humidifier, and therefore regular cleaning work is required. However, the cleaning work of the sprinkling nozzle was not possible to remove the nozzle pipe despite the fact that the work content was fine and complicated, so the maintenance and inspection port of the limited area provided on the exterior panel of the humidifier was used. It was a difficult and time-consuming task that had to be done.

Therefore, in view of the problems of the prior art, the object of the present invention is to provide a nozzle pipe arranged above the water supply filter,
Focusing on that there is no obstacle even if there is some water leakage,
By attaching this to the water circulation system in a detachable manner, it is possible to take out the sprinkling nozzle together with the nozzle pipe to the outside of the device, and to provide a mounting structure for the nozzle pipe of the humidifier, which allows cleaning work to be completed easily in a short time. Especially.

Means for Solving the Problems A structure of the present invention for achieving the above object is to provide a nozzle pipe having an open water supply end and a closed water stop end, and a sprinkling nozzle disposed in an intermediate portion, and circulating water. A first support pipe fixed to a water supply pipe for transmitting water and slidably fitted to a water supply end of the nozzle pipe, and a second support pipe fixed to a fixing member and slidably fitted to a water stop end of the nozzle pipe. The nozzle pipe is detachably supported between the first support pipe and the second support pipe in the upper portion of the water supply filter, and communicates with the water supply pipe through the first support pipe, and through the water spray nozzle. The main point is to spray circulating water to the water supply filter.

A positioning bolt may be provided at the fitting portion between the water supply end of the nozzle pipe and the first support pipe, and a positioning ring may be attached to the water supply end side of the nozzle pipe to stop the water of the nozzle pipe. The end may be fitted with the second support pipe by interposing a compression spring between the end and the fixing member.

Operation According to the configuration of the present invention, the water supply end of the nozzle pipe is fitted and supported by the first support pipe,
It communicates with the water supply pipe through a support pipe. Therefore, the nozzle pipe can introduce the circulating water fed through the water feeding pipe and spray the circulating water to the water supply filter through the watering nozzle. Further, since the water stop end of the nozzle pipe is fitted and supported by the second support pipe and is hermetically sealed, the circulating water in the nozzle pipe can secure a water pressure necessary for spraying from the water spray nozzle. it can. In addition,
The nozzle pipe is detachably supported between the first support pipe and the second support pipe.
It can be easily removed from the support pipe and the second support pipe and taken out to the outside.

If the positioning bolt is arranged at the fitting portion between the water supply end of the nozzle pipe and the first support pipe, the positioning bolt will be
Since the relative position of the nozzle pipe with respect to the support pipe can be fixed, the nozzle pipe does not easily move or come off from the first support pipe even if mechanical vibration or the like occurs. Further, when the positioning ring is attached to the water supply end side and the compression spring is interposed at the water stop end side, the nozzle pipe can always be urged toward the first support pipe side by the compression spring. Good water-tightness can be easily realized between the first support pipe and the first support pipe, and the nozzle pipe is pushed to the second support pipe side against the compression spring so that the water supply end side is the first support pipe. Can be easily removed from.
