Next, the operation of the compressor 100 configured in this manner will be described.
As shown in FIG. 3, outside air sucked into the housing 1 from the air intake 8A in the direction indicated by the arrow 30 is drawn into the air intake 11A of the compressor main body 11. As shown in FIG. As shown in FIG. 4, the air compressed by the compressor body 11 is discharged from the discharge port 11B of the compressor body 11. As shown in FIG. The compressed air heated to a high temperature by being compressed is supplied to the aftercooler 19 through the flow path 31A. The electric fan 18 blows the air in the housing 1 toward the aftercooler 19 in the direction indicated by the arrow 32A to cool the aftercooler 19 . The compressed air cooled by the aftercooler 19 is supplied to the air tank 12 through the flow path 31B and stored in the air tank 12 .

A liquid absorbing member 20 is arranged in the liquid storage chamber 10 to receive water discharged from the diffusion nozzles 21A and 21B.

In this embodiment, the water in the air tank 12 is diffused and discharged from the diffusion nozzles 21A and 21B in a shower-like manner, and the liquid absorbing member 20 receives the water thus discharged. In this way, the liquid absorbing member 20 absorbs the water that is diffused and released in the form of a shower, so that the water absorbed by the liquid absorbing member 20 tends to evaporate naturally. Therefore, it is possible to reduce the frequency of the operation of discarding the water absorbed by the liquid absorbing member 20 .
Therefore, according to the present embodiment, it is possible to provide the compressor 100 that makes it easy to discharge the water accumulated in the air tank 12 .

Further, in the present embodiment, the diffusion nozzles 21A and 21B diffuse and discharge the water sent from the discharge channel 33A in a fan-shaped shower in the horizontal direction. In this configuration, the water sent from the discharge channel 33A is discharged over a wide area of the upper surface of the liquid absorbing member 20, so that the evaporation efficiency of water can be improved. Moreover, since the water is discharged horizontally, the height dimension required for diffusing the water can be suppressed. Accordingly, the compressor 100 can be downsized by reducing the height dimension.

In addition, in this embodiment, the cooling chamber 17 is arranged behind the compressor body 11 or the air tank 12, and the air flowing inside the housing 1 passes from the periphery of the compressor body 11 through the cooling chamber 17, It is sent toward the liquid member 20 . In this configuration, by applying hot air after cooling compressed air that has reached a high temperature to the liquid absorbing member 20, the evaporation efficiency of water from the liquid absorbing member 20 can be further increased.

Further, in this embodiment, the housing 1 has a tray 7 that can be pulled out, and the liquid storage chamber 10 is formed in the tray 7 . With this configuration, the tray 7 can be pulled out forward for maintenance such as when the liquid absorbing member 20 or the liquid storage chamber 10 is drained or when the liquid absorbing member 20 is replaced. improves.

Further, in the present embodiment, the tray 7 is provided with an inspection hole 7C through which the internal state of the liquid storage chamber 10 can be checked. With this configuration, it is possible to see through the inspection hole 7C whether water is accumulated in the liquid absorbing member 20, whether the liquid absorbing member 20 is dirty, and the like, and it is possible to confirm whether maintenance of the liquid absorbing member 20 is necessary. can be done. Further, when the inspection hole 7C is configured only by a through hole, it becomes possible to easily pull out the tray 7 by inserting a finger into the inspection hole 7C.

Further, in the present embodiment, the tray 7 is provided with outlets 7A and 7B for discharging the air flowing inside the housing 1 to the outside of the housing 1 on the side surface thereof. In this configuration, it is possible to increase the efficiency of evaporating water from the liquid absorbing member 20 because the discharge of water vapor from the water absorbed by the liquid absorbing member 20 to the outside of the housing 1 is facilitated.

The present invention is not limited to the above-described embodiments, and includes various modifications without departing from the technical idea or main features thereof. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the described configurations. Moreover, it is possible to add, delete, or replace some of the configurations of the above-described embodiments with other configurations.

For example, as shown in FIG. 7, the bottom surface 7H of the tray 7 can be inclined so as to become lower toward the front. In this configuration, the moisture in the tray 7 moves forward. Therefore, the liquid absorbing member 20 arranged at the front in the tray 7 can surely absorb the moisture in the tray 7 .

In addition, although the liquid absorbing member 20 is made of sponge in the above embodiment, it is not limited to this, and may be made of other materials having liquid absorption properties.
Further, although the compressor main body 11 compresses air in the above embodiment, it is not limited to this, and may compress gas other than air.
