As such, a device for treating water and supplying it to drinking water is generally used as a water purifier for supplying cold water and hot water after purifying raw water supplied through a water pipe.

When water purifiers are classified according to their shape, a storage type water purifier that stores purified water passed through a filter in a reservoir and is heated or cooled, and a direct type that discharges purified water heated or cooled through a filter without a reservoir. There is a water purifier.

Recently, in order to reduce the size of the water purifier and reduce the cost, the use of a direct type water purifier without a water tank is increasing rapidly.

1 is a block diagram conceptually showing a configuration of a general direct type water purifier according to the prior art, and FIG. 2 is a view schematically illustrating a configuration of a cold water tank of a general direct type water purifier according to the prior art.

The water purifier is generally equipped with a water supply valve V to open and close the supply of raw water on a water supply pipe Q through which raw water is supplied, and this water supply pipe Q is connected to the water filter 20. In the water filter 20, a plurality of filter devices may be selected so that a filtering process such as removing suspended substances, deodorizing, and sterilizing bacteria causing waterborne diseases may be performed, including suspended solids mixed in raw water. Mainly applied to sediment filter, pre-carbon filter, hollow fiber membrane filter / reverse osmosis filter, post-carbon filter Etc. are used.

The upper portion of the hot water tank 30 is combined with a separate air vent pipe 32 to discharge the internal pressure.

In the cold water tank 40, a cooling coil 41 is installed to surround an outer circumferential surface of the cold water tank 40 so as to cool the water stored in the inner space, and an upper portion of the cold water tank 40 is provided with purified water supplied through the cold water connection pipe P2. Inlet pipe 42 is coupled to flow into. In addition, a water discharge pipe 43 is coupled to the upper portion of the cold water tank 40, and the water discharge pipe 43 penetrates the cold water tank 40 and is disposed such that a lower end thereof is located below the internal space of the cold water tank 40. . Therefore, the cold water located in the lower portion of the internal space of the cold water tank 40 is discharged through the water discharge pipe 43 and is supplied to the water intake valve 70 through the cold water supply pipe S2.

Meanwhile, a separate air vent pipe 44 is coupled to the upper portion of the cold water tank 40 to prevent a pressure increase due to expansion of the purified water stored therein, and a separate drain pipe 45 is coupled to the lower portion of the cold water tank 40. The drain pipe 45 is for discharging water stored in the internal space of the cold water tank 40, and is used for discharging water to periodically clean the cold water tank 40. The lower end of the drain pipe 45 is provided with a separate plug 46 to open and close the drain pipe 45.

Unlike the hot water tank 30, since the cold water tank 40 can breed bacteria, the drain pipe 45 is combined for internal cleaning, and recently, stainless steel is used to minimize the bacterial growth of the cold water tank 40. Used cold water tank 40 is widely used, in this case, both the inlet pipe 42 and the outlet pipe 43 coupled to the cold water tank 40, as well as the drain pipe 45 all by using stainless steel It is produced in one piece.

In the case of stainless steel, since the thermal conductivity is excellent, the cold water tank 40 is also cooled by the cooling action of the purified water stored in the cold water tank 40, and the drain pipe 45 is also cooled by the heat conduction. In this case, since the drain pipe 45 is for discharging the water of the cold water tank 40, the drain pipe 45 is generally formed to be externally exposed to facilitate the discharge of the water, and the coldly cooled drain pipe 45 is externally exposed. In contact with the air at room temperature condensation occurs on the outer peripheral surface of the drain pipe (45). As a result of the condensation, water droplets are continuously generated at the outer circumferential surface of the drain pipe 45 and flow downward, thereby causing water to leak out of the water purifier case.

In particular, when the water purifier is used for a long time, the amount of leakage due to such a leakage phenomenon increases, contaminating the environment around the water purifier installation place occurs.

The direct water purifier is configured to supply purified water passing through the water filter to the cold water tank and the hot water tank as described in the background art, and then to supply the cold water and the hot water to the water intake valve from the cold water tank and the hot water tank, respectively. Through cold water and hot water can be selectively withdrawn.

The tank body 100 is formed to store the purified water passing through the water filter in the internal space. An inlet pipe 110 is coupled to an upper end of the tank main body 100 so that the purified water passing through the water filter may be supplied to the inner space of the tank main body 100. In addition, the upper end of the tank body 100 is coupled to the water extraction pipe 120 for withdrawing the cold water cooled in the tank body 100 internal space to the intake valve side. The water outlet pipe 120 is coupled through the top wall of the tank body 100, and is disposed such that the bottom thereof is located below the inner space of the tank body 100. In addition, a separate air vent pipe 130 is coupled to the upper end of the tank body 100 to prevent a pressure increase due to expansion of the purified water stored therein.

The drain pipe 140 is coupled to the lower end of the tank body 100 to discharge the water stored in the internal space. As described in the background art, unlike the hot water tank, unlike the hot water tank, bacteria may grow, and thus a periodic cleaning operation is required. For this cleaning, all water stored in the tank body 100 must be discharged. As such, the drain pipe 140 is coupled to discharge all the water from the tank body 100. Since the drain pipe 140 is normally maintained in a closed state and should be opened only when water is to be discharged, a separate opening and closing for opening and closing the bottom of the drain pipe 140 may be performed at the bottom of the drain pipe 140. Member 150 is coupled.

In addition, the tank body 100 may be formed of a stainless steel material in order to minimize bacterial propagation. In this case, the water inlet pipe 110, the water outlet pipe 120, and the drain pipe 140 are also all made of stainless steel and thus, the tank. It may be integrally formed with the main body 100.

The cooling coil 200 is coupled to surround the outer circumferential surface of the tank body 100 so as to cool the water stored in the inner space of the tank body 100. The cooling coil 200 may be configured to cool the tank body 100 in the form of absorbing heat through the refrigerant circulating the refrigeration cycle.

On the other hand, the inside of the tank body 100 is equipped with a guide plate 101 for guiding the flow of water so that the water supplied from the inlet pipe 110 flows through the side wall. The guide plate 101 is positioned above the inner space of the tank body 100 in the form of a flat plate, and is formed to guide the flow of water introduced from the inlet pipe 110 toward the side wall of the tank body 100. By the water flowing along the side wall of the tank body 100 by the guide plate 10, the cooling function of water by the cooling coil 200 surrounding the outer circumferential surface of the tank body 100 is further improved.

The condensation preventing member 300 is coupled to the lower end of the drain pipe 140 to prevent condensation occurring in the drain pipe 140.

As described in the background art, the drain pipe 140 is coolly cooled together with the tank body 100 due to the heat conduction by the cooling of the tank body 100, and thus, when the drain pipe 140 is exposed to the outside, the room temperature state is When it comes into contact with relatively warm air, condensation may occur on the outer circumferential surface of the drain pipe 140 to generate water and leak water. In the present invention, since the condensation preventing member 300 is provided to block external exposure of the drain pipe 140 to prevent condensation of the drain pipe 140, a water leakage phenomenon may be prevented.

The condensation preventing member 300 may have an insertion groove 310 formed on the upper surface of the condensation preventing member 300 so as to cover the outer peripheral surface of the lower end of the drain pipe 140 in a state of being inserted into the concave receiving portion 401 of the heat insulating material 400.

In addition, the opening and closing member 150 for opening and closing the drain pipe 140 is coupled to the lower end of the drain pipe 140, the insertion groove 310 of the condensation preventing member 300 is such an opening and closing member ( It is preferably formed to surround and receive 150). Through this structure, the condensation preventing member 300 blocks not only the external exposure of the drain pipe 140 but also all of the external exposure of the opening and closing member 150, so that all external air contact is made at the peripheral portion of the drain pipe 140. This prevents condensation from occurring.

At this time, the opening and closing member 150 is a sealing stopper 151 which is sealingly inserted into the inner diameter of the drain pipe 140, and an outer stopper that is coupled to surround the outer peripheral surface of the lower end of the drain pipe 140 in a state where the sealing stopper 151 is inserted. 152 can be configured to include. The outer stopper 152 may be formed of a heat insulating material, and although not shown, may be configured to enhance the heat insulating performance in a form in which an air layer is formed in the inner space. According to this structure, the condensation prevention function may be exerted through the outer plug 152 of the opening and closing member 150 in addition to the condensation preventing member 300 at the lower end of the drain pipe 140.

As described above, the cold water tank for the direct type water purifier according to the exemplary embodiment of the present invention is provided with a heat insulating material 400 on the outer circumferential surface of the tank body 100, and the drain pipe 140 is external to the lower end of the heat insulating material 400. The concave accommodating part 401 is formed to be exposed, and the condensation preventing member 300 is inserted into and coupled to the concave accommodating part 401, thereby preventing condensation by blocking external exposure of the drain pipe 140. When the water is discharged through the drain pipe 140, the condensation preventing member 300 may be separated from the recess accommodating portion 401 to smoothly proceed with the water discharge through the drain pipe 140.

5 is a view schematically showing the structure of a cold water tank for a direct type water purifier according to another embodiment of the present invention.

At this time, the closing cap 600 may be formed in the form of a container in which the top surface of the guide protrusion 610 is formed so that the edge is protruded upward to enable the storage of water.

As the closing cap 600 is mounted in this way, even if condensation occurs in the drain pipe 140, even if moisture is generated, the generated moisture does not leak to the outside of the main case 500 to the closing cap 600. It is kept in a stored state to prevent environmental pollution due to water leakage.

In addition, when the condensation preventing member 300 is disposed at the lower end of the closing cap 600 in the inserted state protruding downward from the concave receiving portion 401 of the heat insulating material 400 is coupled to the main case 500, in this process The condensation preventing member 300 may be configured to be compressed and coupled between the finishing cap 600 and the heat insulating material 400, and the gap between the condensation preventing member 300 and the recess accommodating part 401 is more closely contacted through the structure. Therefore, the external air exposure of the drain pipe 140 through the gap may also be more completely blocked. At this time, since the air chamber 320 is formed inside the condensation preventing member 300, the condensation preventing function of the condensation preventing member 300 may be strengthened to achieve a more perfect adhesion performance.
