The waiting room 10 is open to the outside and is used as a facility where users temporarily wait, such as a bus stop, a crossing waiting facility, or a smoking room.

The pumping module 20 is installed on one side of the waiting room 10 and serves to pressurize and supply water. As shown in FIG. 2, it includes a storage unit 21 for storing water and the storage unit ( It includes a pumping unit 22 that pumps the water of 21), a transfer unit 23 that transfers the water pressurized by the pumping unit 22, and a control unit 24 that controls the operation of the pumping unit 22. It is composed.

The storage unit 21 has a space formed inside it, and stores water through the space. In addition, if necessary, an opening and closing hole can be formed on the side to supply water, and it is preferably made of a semi-transparent synthetic resin material so that it can be confirmed whether water is stored inside. In this case, the storage part 21 is replaceable. It can be configured to support the entire module through a separate structure. Additionally, a water level sensor can be installed inside so that the control unit 24 can recognize the level of water storage.

The pumping unit 22 serves to pump water from the storage unit 21 and discharge it to the transfer unit 23, and includes a motor that operates through an external power source and a pump that operates by the motor to create pressure. It is configured to include, wherein the suction port of the pump communicates with the storage unit 21 and the discharge port of the pump communicates with the transfer unit 23.

The control unit 24 includes a switch unit operated by an administrator and controls the operation of the pumping unit 22.

If necessary, the control unit 24 can include a separate temperature sensor to control the operation of the pumping unit 22 based on the ambient temperature detected by the temperature sensor. If necessary, the control unit 24 can control the operation of the pumping unit 22 based on the ambient temperature detected by the temperature sensor. It can be configured to set the amount of water pumped by the pumping unit 22 as a standard.

In addition, it can be configured to output a separate alarm when the water stored in the storage unit 21 is used up, and furthermore, it can be configured to send an alarm to the manager's smartphone in case of some malfunction or water is used up. .

The transfer unit 23 serves to transfer pressurized water, and is made up of general pipes. Synthetic resin pipes or metal pipes can be applied, and the pumping unit 22 delivers the water at a pressure of about 5 bar to 10 bar. Since it is pressurized, it is desirable that the transfer unit 23 be constructed of a pipe that can withstand a pressure of at least 15 bar.

Meanwhile, as shown in FIG. 3, the spray module 40 serves to spray high-pressure water supplied through the transfer unit 23 to the outside, and has a spray body 41 with a space formed inside. and an inlet 42 formed on a side of the spraying body 41 and communicating with the transfer unit 23, a plurality of nozzles 43 formed in the longitudinal direction on the outer surface of the body 41, and a lower end of the spraying body 41. It is configured to include a bottom plate 44 formed in.

The spray body 41 accommodates high-pressure water in the internal space, and is preferably configured to have a constant cross-sectional shape in the longitudinal direction.

An inlet 42 is formed on the side of the injection body 41, and the transfer unit 23 is coupled to the inlet 42, so that high-pressure water is supplied into the injection body 41 through the inlet 42.

The nozzles 43 are disposed in the longitudinal direction of the injection body 41. In the case of a circular cross-section, the nozzles 43 are preferably disposed at the same location, and are preferably disposed at the same distance.

Additionally, it is desirable to set the discharge angle to 20 to 45 degrees downward from the horizon.

If it is less than 20 degrees, the amount sprayed to the side is large and the temperature reduction in the lower area is low, which is inappropriate. If it is over 45 degrees, a lot of spray is generated in the lower area and the temperature reduction in the side area is low, making it inappropriate.

Meanwhile, Figure 4 is a graph showing the evaporation rate in the air according to the average particle diameter of the sprayed water. In the above figure, it can be seen that the average particle diameter of the sprayed water shows a high evaporation rate in the range of 10㎛ to 16㎛, and in particular, the highest evaporation rate at 13㎛, and the internal pressure of the water at this time is 2 to 10 bar.

Therefore, it is desirable that the water particles sprayed through the nozzle 43 have a diameter of 10㎛ to 16㎛, and the pressurized water inside the spray body 41 is set in the range of 5bar to 10bar.

That is, when the nozzle 43 sprays 5 bar to 10 bar of pressurized water in the form of a spray with an average diameter of 10 ㎛ to 16 ㎛, the water evaporates quickly, which has the effect of lowering the surrounding temperature in a short time.

In addition, a bottom plate 44 is disposed at the bottom of the spray body 41, and the bottom plate 44 is preferably installed in a position so as not to interfere with water sprayed from the nozzle 43.

The bottom plate 44 serves to collect condensation water generated due to a temperature difference between the spray body 41 and the outside air and leakage water generated due to partial leakage when it falls and discharges it to the outside. Therefore, it may be configured to include an appropriate slope and a separate drain 45 for discharging the collected condensate to the outside.

Meanwhile, as shown in FIG. 5, the blowing module 60 includes a cylindrical blowing body 61, a plurality of blowers 62 installed at regular intervals on the front of the blowing body 61, and the blowing body ( A plurality of blowers 63 installed on the back of the blower body 61, a distribution plate 64 installed inside the blowing body 61, a plurality of through holes 65 formed in the distribution plate 64, and the blower 62 ) and an aroma supply unit 70 attached to the side of the blowing body 61 to provide an appropriate aroma to the discharged air.

The blowing body 61 has a cylindrical shape with an internal space formed therein, and is arranged in parallel with the spraying body 41. In addition, the length of the blowing body 61 is equal to or longer than the spraying body 41.

A blower 62 is formed on the front surface of the blower body 61 in the direction in which the spray body 41 is located, and the blower 62 is formed in the same number at the same position as the nozzle 43. .

Therefore, the wind discharged through the blower 62 serves to scatter the fine water sprayed from the nozzle 43 to the surroundings.

In particular, as shown in FIG. 6, an insertion member 67 including two support parts 69 and a semicircular part 68 formed in the inner direction between the support parts 69 is inserted and fixed into the blower 62. After the wind inside the blowing body 61 flows into the side of the semicircular part 68, they collide with each other to form a rotating flow.

Therefore, the wind discharged through the blower 62 has a strong swirl shape, so it has the effect of rapidly scattering the sprayed fine water.

The insertion member 67 is coupled to the blower 62 by its own elastic force, but if necessary, it can be fixed with a separate fixture such as a bolt.

Meanwhile, as shown in FIG. 7, the distribution plate 64 with the through hole 65 serves to maintain the air pressure formed inside the blowing body 61 constant in the longitudinal direction, so that the air is discharged from all blowing holes 62. Make sure the wind blowing is uniform.

Additionally, the aroma supply unit 70 serves to supply an appropriate scent into the blowing body 61.

The blower 63 supplies external air into the blowing body 61 and discharges wind through the blower 62, and is composed of a drive motor and a fan attached to the drive motor. The blower 63 is controlled through the control unit 24.

That is, when the control unit 24 operates the pumping unit 22 and the blower 63 simultaneously, the sprayed fine water scatters to the surroundings.
