In addition, the first switching valve 120 is further connected to the wash water discharge pipe 144, the wash water discharge pipe 144 is connected to the drain tank 190. In some cases, the washing water discharge pipe 144 may be extended to the outside of the hull without installing the drain tank 190 in a vessel (not shown). Drinking water supply pipe 145 is further connected to the second switching valve 130.

The pump 140 is connected to the water supply pipe connecting the first switching valve 120 and the second switching valve 130. The pump 140 is connected to a pipe line 141 for receiving the water produced in a water dispenser (not shown), and a check valve 142 is installed between the pump 140 and the water supply pipe 143. Therefore, when the pump 140 is operated, the water produced in the water dispenser is supplied to the water supply pipe 143 through the pipeline 141. The check valve 142 prevents water flowing into the main body from flowing back into the pump 140.

The air supply means 150 for supplying compressed air is connected to the main body 111. The main body 111 and the air supply means 150 are connected to the compressed air supply pipe 151, and the check valve 152 is installed in the compressed air supply pipe 151. The check valve 152 prevents air or water in the main body 111 from flowing back to the air supply means 150.

A drain pipe 171 is connected to the lower end of the main body 111, and a drain valve 170 is installed at the drain pipe 171. When the drain valve 170 is opened, water in the main body 111 is discharged to the drain tank 190 through the drain pipe 171.

Vessel drinking water supply apparatus 100 according to an embodiment of the present invention has a structure as described above. Hereinafter, the operation of the marine drinking water supply device 100 will be described.

First, the first switching valve 120 allows the water supply pipe 143 and the first connection pipe 121 to pass through each other, and the washing water discharge pipe 144 is closed. The second switching valve 130 closes the water supply pipe 143 and allows the second connection pipe 131 and the drinking water supply pipe 145 to communicate with each other. This state is defined as a first state.

In addition, the first switching valve 120 allows the first connection pipe 121 and the washing water discharge pipe 144 to pass through each other, the water supply pipe 143 is closed, and the second switching valve 130 is the water supply pipe 143 and the second. The connection pipe 131 is connected to each other and the drinking water supply pipe 145 is defined as a closed state of the second state.

The first switching valve 120 and the second switching valve 130 shown in FIG. 1 are in a first state.

Therefore, when the pump 140 is operated, the water produced in the water dispenser flows to the first filtration means 112 through the pipe line 141 and the water supply pipe 143. Water is filtered through the first filtering means 112, and then passes through the mineral adding means (113). The water passing through the mineral adding means 113 is filtered by the second filtering means 114 and then flows to the drinking water supply pipe 145 through the second connecting pipe 131.

At this time, since pressure is applied to the water in the main body 111 by the pressure of the compressed air supplied into the main body 111 by the air supply means 150, the pressurized water flows through the drinking water supply pipe 145. . Therefore, water can be supplied through the drinking water supply pipe 145 to a high position of a residence (not shown) installed in the vessel.

The operator may appropriately adjust the internal pressure of the main body 111 by adjusting the pressure of the compressed air supplied to the main body 111 by the air supply means 150 according to the height of the drinking water supply pipe 145 is connected.

Although not shown, the air supply means 150 is stopped when the internal pressure of the main body 111 reaches a predetermined pressure. The pump 140 also stops operation when the internal pressure of the main body 111 is higher than a predetermined pressure.

However, when the pump 140 and the air supply means 150 continue to operate without stopping due to failure or the like, the internal pressure of the main body 111 is excessively increased. In this case, the safety valve 160 is opened to discharge the water or air in the main body 111 to the drain tank 190 through the pressure reducing tube 161 to lower the internal pressure of the main body 111.

As the drinking water supply device for ship 100 is used, debris of the foreign matter or mineral addition means 113 accumulated in the first filtering means 112 and the second filtering means 114 may be accumulated and filtered. The amount of water will be reduced. Therefore, since the performance of the vessel drinking water supply device 100 is deteriorated, the foreign matter accumulated in the first filtration means 112 and the second filtration means 114 should be removed after treating a certain amount of water. This will be described with reference to FIG. 2.

Figure 2 is a schematic diagram for explaining the washing of the drinking water supply apparatus for ships shown in FIG.

Referring to FIG. 2, the first switching valve 120 and the second switching valve 130 are switched to the second state defined above. Accordingly, the water supplied to the water supply pipe 143 by the pump 140 sequentially passes through the second filtration means 114, the mineral addition means 113, and the first filtration means 112 through the second connection pipe 131. After rough as it is discharged to the drain tank 190 through the washing water discharge pipe 144. At this time, the drinking water supply pipe 145 is blocked by the second switching valve 130 does not flow water.

Foreign matter accumulated in the first filtration means 112 and the second filtration means 114 in the course of passing water through the second filtration means 114, the mineral addition means 113, and the first filtration means 112. Along with this water is discharged to the washing water discharge pipe 144 is removed.

That is, when the first switching valve 120 and the second switching valve 130 is in the first state as shown in FIG. 1, the water supplied by the pump 140 is the first filtration means 112 and the second. Since the filter is passed from one side of the filtering means 114 to the other side, foreign substances contained in the water remain on one side of the first filtering means 112 and the second filtering means 114, respectively. However, when the first switching valve 120 and the second switching valve 130 is switched to the second state as shown in FIG. 2, the water is discharged from the first filtering means 112 and the second filtering means 114. Since it passes from one side to the other side, foreign substances remaining on one side of the first filtering means 112 and the second filtering means 114, respectively, by the flow of water, the first filtering means 112 and the second filtering means 114. It is separated from one side of.

Therefore, the first filtration means 112 and the second filtration means 114 are manufactured so that the attached foreign matter can be easily separated. For example, although not shown, the first filtration means 112 and the second filtration means 114 may use a porous filter having a larger hole from one side to the other side.

The foreign matter accumulated on the bottom of the main body 111 is discharged through the drain pipe 171 together with the water in the main body 111 when the drain valve 170 is opened.

As described above, when the vessel drinking water supply device 100 is washed, the operation of the air supply means 150 may be stopped.

When the foreign matter accumulated in the first filtration means 120 and the second filtration means 114 is removed, since the performance of filtering water is restored, the drinking water supply capacity of the marine drinking water supply device 100 is restored again. Therefore, by regularly cleaning the drinking water supply device 100 for ships can maintain the performance continuously.

While the vessel drinking water supply apparatus according to the embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiments presented herein, those skilled in the art to understand the spirit of the present invention within the scope of the same idea Other embodiments may be easily proposed by adding, changing, deleting, or adding components, but this will also fall within the spirit of the present invention.
