The supplied water pipe 163 extends through the bottom of the primary cooling chamber 112 to the upper portion of the primary cooling chamber 112.

In addition, a spray head 165A is installed at an upper end of the water pipe 163. The spray head 165A has a hemispherical shape, and many nozzles 167 are formed in the entire hemisphere. Therefore, the cold water 3W injected through the nozzle 167 is widely sprayed in a wide range in the hemispherical form of the spray head 165A.

In addition, the first blowing panel 180A is mounted on the main body 110 on the opposite side facing the one side on which the spray head 165A is installed. Here, the filter 187 is mounted on the first blower panel 180A to block foreign matter from entering the main body 110 in addition to the air. The blower panel will be described in detail later.

In addition, a second air blowing panel 180B is installed on an upper portion of the spray head 165A, that is, a ceiling that forms a boundary with the secondary cooling chamber 113 having three levels. Therefore, the air introduced into the main body 110 through the first blowing panel 180A is blown through the first cooling chamber 112 to the secondary cooling chamber 113 through the second blowing panel 180B.

Below, the secondary cooling chamber 113 which is 3rd floor is demonstrated.

The first discharge pipe 151 communicates with the bottom of the secondary cooling chamber 113, and the first discharge pipe 151 extends into the left space 141L of the container 120, and extends from the first pump 161. The water supply pipe 163 passes through the bottom of the primary cooling chamber 112 and the bottom of the secondary cooling chamber 113 and extends to the upper portion of the secondary cooling chamber 113, and the spray head is disposed at the upper end of the water supply pipe 163. 165B is installed.

In addition, the third blower panel 180C is installed on the top of the spray head 165B, that is, on the ceiling bordering the discharge chamber 114 having four layers. Therefore, the air introduced into the secondary cooling chamber 113 through the second blowing panel 180B is blown to the discharge chamber 114 through the third blowing panel 180C after passing through the secondary cooling chamber 113.

The fan 190 is located in the discharge chamber 114, and after the outside air passes through the first blowing panel 180A as the fan 190 operates, the primary cooling chamber 112 and the secondary cooling chamber 113 are used. After passing through the discharge chamber 114 is discharged through the grill 191. As described above, the grill 191 may control the discharge direction as the electric motor turning in the left and right directions.

Hereinafter, the blower panel will be described with reference to FIG. 7.

As shown in FIG. 7, in the blower panel 180, a blocking film 185 having an area capable of blocking the hole 183 is positioned between two panels 181 having a plurality of square holes 183 formed therein. An upper end of the blocking film 185 is fixed between the two panels 181, and an unfixed free portion of the blocking film 185 is located outwardly through the hole 183 of the panel located in the air propagation direction. In the blower panel 180 having such a structure, air travels in one direction by the blocking film 185 and is blocked in the opposite direction. Therefore, when the fan 190 is operated in the discharge chamber 114, the outside air moves along the first blower panel 180A, the second blower panel 180B, and the third blower panel 180C, but does not proceed in the reverse direction. Ice water (1W) and cold water (3W) sprayed from the spray heads (165A, 165B), even if hit the blowing panel 180 on the opposite side, the water flows down without passing through each blowing panel 180 Get off.

Therefore, the ice water 1W of the secondary cooling chamber 113 is blocked from flowing to the primary cooling chamber 112 by the second blowing panel 180B, and the cold water of the primary cooling chamber 112 is also the first. Outflow of the main body 110 is blocked by the blower panel 180A.

On the other hand, as shown in Figure 8, the doors (118H, 118L) formed in the upper and lower parts of the main body 110 is a sliding door that opens and closes by turning out of the main body 110, the handle is on the top of the doors (118H, 118L). It is formed, the lower portion of the doors (118H, 118L) is hinged to the main body 110 is opened to swing downward and to swing upward to close. In such a structure, the upper and lower ends of the doors 118H and 118L are formed with an inclined surface lowering inward from the outside of the main body 110, and the main body 110 also corresponds to the upper and lower ends of the doors 118H and 118L. 110 is formed as an inclined surface lowering from the outside to the inside. In this manner, the ice water 1W and the cold water 3W inside the main body 110 do not flow out. In addition, since the ice water 1W and the cold water 3W can flow out through the sides of the doors 118H and 118L, the closing membrane 119 corresponds to the edges of the doors 118H and 118L. Is attached to the side.

The following describes the operation relationship of the cold air configured as described above.

The user opens the lower door 118L formed at the side of the main body 110, opens the casement door 121 of the container 120 upward, and then puts ice 1 and water into the left space 141L, The coolant 3 and water are put into the right space 141R.

When the fan 190, the first pump 161, and the second pump 162 are operated, the outside air passes through the first blower panel 180A after passing through the filter 187 by the fan 190, After passing through the primary cooling chamber 112, it passes through the second blowing panel 180B and flows into the secondary cooling chamber 113. Then, the second cooling chamber 113 passes through the third blowing panel 180C and flows into the discharge chamber 114, and is discharged out of the main body 110 through the grill 191 through the fan 190.

In such a process, the cold water 3W filled in the right space 141R of the container 120 passes through the spray head 165A of the primary cooling chamber 112 through the second pump 162. 112 is injected into the interior. At this time, the advancing direction of the air and the injection direction of the cold water (3W) is opposite to each other, so the effect of heat exchange is excellent.

Meanwhile, the ice water 1W filled in the left space of the vessel 120 is sprayed into the secondary cooling chamber 113 through the spray head 165B of the secondary cooling chamber 113 through the first pump 161. do. In addition, the advancing direction of air and the spraying direction of the ice water 1W are opposite to each other, so the effect of heat exchange is excellent.

Here, the high temperature outdoor air is introduced into the main body 110 and then cooled by the cold water 3W in the primary cooling chamber 112 and by the ice water 1W in the secondary cooling chamber 113. As the air cooled first by cold water (3W) is secondly cooled by ice water (1W), the amount of heat cooled by the ice 1 stored in the left space 141L is reduced, and the cooling effect increases as much as the ice. The consumption is reduced.

In the above-described present invention, the refrigerant 3 is filled in the right space 141R. However, the refrigerant may be ice. Alternatively, the refrigerant may be filled with water instead of the refrigerant, and thus, the effect of cooling the high temperature outdoor air is excellent. Likewise, it is better in terms of energy efficiency than a cooler that cools air directly with ice water.

Meanwhile, the cold water 3W injected from the primary cooling chamber 112 is collected through the bottom of the primary cooling chamber 112 and communicated with the bottom of the primary cooling chamber 112 through the second discharge pipe 152. It is drained to the right space 141R of 120. The ice water 1W injected into the secondary cooling chamber 113 is also drained to the left space 141L of the container 120 through the first discharge pipe 151.

The ice water 1W drained to the first discharge pipe 151 and the cold water 3W drained to the second discharge pipe 152 are collected in the left space 141L and the right space 141R, respectively. It is cooled by (3). And it flows down to the left collection tank 143L and the right collection tank 143R through the net 135 formed in the 2nd partition 132. As shown in FIG. Thus, the ice water 1W and cold water 3W which flowed down to the left water tank 143L and the right water tank 143R cool | recirculate the air by recirculating by the 1st pump 161 and the 2nd pump 162. FIG.

On the other hand, although not shown in the drawing, a drain pipe is formed in the left and 143L and the right collection tank (143R), the valve is formed in the drain pipe is discharged to remove all the water stored in the container when not using a cool air do.
