Description

[Detailed description of the invention] An eliminator is inserted in the air duct to prevent water droplets condensed on the heat exchanger inside or water droplets accompanying water humidification from being sent together with the air. Regarding the air blower installed.

[Conventional technology]

The conventional air blowing device mentioned above, for example, like the air conditioner shown in Fig. 2, has a heat exchanger (3), a humidifier, etc. A device (4), an eliminator (5), and an air supply fan (6) are installed in order to remove water droplets generated from the heat exchanger (3) and mixed into the air supply, or for humidification supplied from the humidifier (4). The structure is configured so that water droplets are placed on the air flow to promote evaporation of the water droplets in a suspended state, and the eliminator (5) captures water droplets that could not evaporate before reaching the eliminator (5), and is supplied from the humidifier. If the water droplets mixed in with the air flow do not form a mist that easily floats, these water droplets tend to fall and accumulate in the air duct before reaching the eliminator, causing the water droplets to fall from the air duct. This caused the air duct to corrode early.

The present invention has been made in view of the above-mentioned circumstances, and provides an air blower that actively promotes the evaporation of water droplets that tend to fall onto the inner bottom surface of the air duct, thereby preventing water droplets from accumulating inside the air duct. The purpose is to

[Means to solve the problem]

The characteristic configuration of the present invention for achieving the above object is that in the above-mentioned air blower, on the upper side of the eliminator in the air blowing direction,
The net-like body is mounted in such a manner that its downward edge is separated from the inner circumferential surface of the air supply duct, and this configuration provides the following effects.

[For production]

In other words, the net-like body attached to the upper side of the eliminator in the air supply direction easily catches water droplets that are about to fall before reaching the eliminator, and the water droplets captured by this net-like body move along the net-like body. By being exposed to the airflow while flowing down, some of them are blown away in the form of mist and evaporation is promoted while floating in the airflow, and some of them are directly evaporated on the way down.

Water that is not blown away and does not evaporate during the flow tries to fall from the downward edge of the reticular body, but the amount of water droplets is smaller than the total amount of water captured by the reticular body. Since there are fewer water droplets, the water droplets are easily blown away in the form of a fine mist by the airflow, and fewer water droplets fall on the inner bottom surface of the airflow gutter.

〔Effect of the invention〕

As mentioned above, water droplets that tend to fall onto the inner bottom surface of the air duct are captured by the net-like body and evaporation is actively promoted, making it possible to provide an air blower that prevents water droplets from staying inside the air duct. Ta.

〔Example〕

As shown in Figure 1, the U formed inside the casing (1)
A heat exchanger (3), a humidifier (4), an eliminator (5), and an air supply fan (6) are installed in order from the upper side to the lower side of the air supply direction (arrow) of the letter-shaped air supply path (2). A motor (7) for driving the air blowing fan is provided below the air blowing fan (6) to form a vertical air handling unit as an example of a blowing device.

The humidifier (4) includes a nozzle (4a) that spouts water droplets in the form of mist toward the upper side in the air supply direction.
The water droplets ejected from the eliminator (5) are configured to stay in the air for as long as possible until they reach the eliminator (5), thereby promoting evaporation of the water droplets.

Then, a metal mesh (8) is attached at a position halfway between the eliminator (5) and the nozzle (4a) in such a manner that the downward #edge (8a) is separated from the inner peripheral surface of the air duct (2). The net (8) is configured to capture water droplets that tend to fall onto the bottom surface of the air supply duct (2) and actively promote their evaporation.

If the eliminator (5) and the nozzle (4a) are arranged in the winding path of the air supply duct (2) as in this embodiment,
The route from the nozzle (4a) to the eliminator (5) is short. However, by providing the above-mentioned net (8), water droplets can be captured by the net (8) before being captured by the eliminator (5) and their evaporation can be promoted. , can enhance the humidification effect.

[Another example]

The net (8) is not limited to metal, but can be made of fiber as long as it is breathable, a plastic net such as vinylidene chloride, or even a plate-like object such as a punched medal with many through holes formed therein. In this example, two nets (8), (8) are arranged side by side along the air supply direction, but only one net or three or more nets may be used. Nets may be installed in parallel.

In this embodiment, the net (8) is fixed in position with respect to the casing (1), but it may be attached so that the fixed position can be changed. The structure may be such that the position can be changed by swinging.

The air blower of the present invention is not limited to an air conditioner such as the air handling unit shown in the embodiment, but is also applicable to a blower for cooling only, a blower for heating only with a humidifying function, and a blower for simply blowing air. This also includes the air blower provided.

Note that although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
