Description

The storage tank is configured to receive the water introduced from the water inlet and to discharge the water through the water outlet.

At this time, when water flowing into the storage tank is rapidly mixed with water already stored in the storage tank, recently introduced water and already stored water can be mixed and discharged.

In particular, when the storage tank is used as a cold water tank, the water is cooled and stored at the temperature required for the outflow. However, the water (hot water) flowing into the storage tank is rapidly mixed with the water (cold water) There is a problem that water mixed with cold water and cold water can not be dispensed.

In order to solve such a problem, a structure is adopted in which the water is discharged from the lower side of the storage tank by using the specific gravity of water.

The cooling unit 300 may further include a cooling unit 300 for cooling the water contained in the tank main body 200. [

In particular, although the storage tank 100 according to an embodiment of the present invention includes the cooling unit 300 in FIGS. 1, 2, and the like, the storage tank 300 according to the present invention is not limited to the structure shown in FIG. As a matter of course, a structure not including the cooling portion is also possible.

First, the tank body 200 is provided with a space capable of receiving water therein, and includes a water receiving part 230 through which water flows into the tank body 200, and water contained in the tank body 200, And a water outlet 240 to be discharged is provided.

The shape and structure of the tank main body 200 are not particularly limited, but may be divided into two or more bodies in order to facilitate the installation of the influent water stabilizing means 400 and / or to improve thermal conductivity and adiabatic characteristics, And then formed into a composite.

2 and 3, the tank body 200 may have a first body 210 and a second body 220 joined together to form an inner space. In FIGS. 2 and 3, the first body 210 and the second body 220 are shown to be combined after being divided in the longitudinal direction, but the direction of division is not particularly limited.

At this time, it is preferable that a sealing member 250 is installed to prevent leakage at the joint portion when the first body 210 and the second body 220 are combined, 210). The first body 210 and the second body 220 may be coupled by fastening a fastening member such as a screw to a plurality of fastening portions 217 and 227, It may be formed in an appropriate number at appropriate positions in consideration of the pressure inside the main body 200 and the shape of the tank main body 200. [

6, the water inlet portion 230 of the tank body 200 includes a water inlet 231 formed in the upper portion of the first body 210 of the tank body 200. As shown in FIG. The inlet 231 may be formed with a plurality of openings 232 to supply inflow water to the tank main body 200 while stabilizing the inflow water from the inlet pipe 238.

In addition, a buffer space portion 235 may be formed in the receiving portion 230. The buffer space 235 is formed by mixing the water supplied from the water inlet pipe 238 with the water contained in the buffer space 235 before the inflow water flows into the tank main body 200, As shown in FIG. In order to form the buffer space 235, the water inlet 230 may have a protrusion 233 protruding from the upper surface of the tank body 200. In order to prevent the water introduced through the inlet pipe 238 from being directly supplied to the inlet 231 and to efficiently stabilize the inflow water in the buffer space 235, the buffer space 235 is connected to the inlet 231 at a position out of the upper horizontal position.

An upper surface of the buffer space 235 is closed through a cover plate 237 and a sealing member such as an O-ring may be provided between the protrusion 233 and the cover plate 237 to prevent leakage. The cover plate 237 may be coupled to the tank body 200 by a fastening portion 234.

The water outlet portion 240 of the tank body 200 includes a water outlet 241 formed in the upper portion of the first body 210 of the tank body 200. The water outlet 240 may also include a buffer space 245 similar to the water inlet 230. The side surface of the buffer space portion 245 may be formed by the projecting portion 243 and the upper surface may be closed by the cover plate 247. [ The cover plate 247 may be coupled to the tank body 200 by a fastening portion 244 with a sealing member such as an O-ring interposed therebetween.

2 and 7, the water outlet 240 may include an outflow guide pipe 246 extending to a lower portion of the tank body 200 to allow water to flow out from the lower portion of the tank body 200 . The water exiting through the water guide pipe 246 can be supplied to the user through the water outlet 241 and the buffer space 245 and the water outlet pipe 248.

The tank main body 200 may be provided with an air discharge check valve 500 for discharging the air contained in the tank main body 200 to the outside when water flows into the tank main body 200, The air discharge check valve 500 may be installed in the check valve seat 249 formed in the water outlet 240, but the installation position thereof is not limited. In particular, when the storage tank 100 according to an embodiment of the present invention is used as a direct-acting tank, the air discharge check valve 500 discharges air when water is introduced into the tank body 200 , It is possible to prevent the water from flowing smoothly due to the internal pressure of the tank body 200.

The water inlet pipe 238 and the water outlet pipe 248 may be integrally formed with the cover plates 237 and 247. The water inlet pipe 238 and the water outlet pipe 248 may be integrally formed with the cover plates 237 and 247, It is defined as belonging to the range of the intake pipe 238 and the water pipe 248.

The tank body 200 may be equipped with a temperature sensor 260 for measuring the temperature of the water contained in the tank body 200. In order to drain the water contained in the tank body 200 to the outside, A drain portion 270 may be provided under the tank body 200.

Meanwhile, the storage tank 100 according to an embodiment of the present invention can be used as a cold water tank. Since the low temperature water is located in the lower portion of the storage tank 100, the storage tank 100 used as the cold water tank is configured to allow water to flow out from the lower portion of the tank body 200 through the water guide pipe 246 . In order to prevent the water being received from being rapidly mixed with the low temperature water located below, i.e., to keep the temperature of the water to be discharged at a low level, As shown in FIG.

Meanwhile, an outflow adiabatic member 280 may be installed between the inlet portion 230 and the outlet portion 240. The waterproofing and insulating member 280 functions to prevent the heat transfer between the water inlet 230 and the water outlet 240 to maintain the water temperature.

The inflow water stabilizing means 400 provided in the storage tank 100 according to an embodiment of the present invention is provided in the tank main body 200 so that inflow water introduced from the inflow portion 230 flows into the tank main body 200 To be rapidly mixed with the water stored in the water tank. That is, the inflow water stabilizing unit 400 mixes inflow water with the stored water in a state where the inflow water is stabilized as much as possible, thereby preventing rapid mixing of inflow water and stored water.

2 and 4 to 7, the inflow water stabilizing means 400 is configured to separate the inflow water space 201 into which the inflow water flows from the storage water space 202 in which the storage water is stored, 201 and a reservoir space 420 having a communication opening 425 for communicating the reservoir space 202 with each other.

In this case, when the tank body 200 is formed by the first body 210 and the second body 220, the partition member 420 may be formed on the first body 210. Accordingly, the partition member 420 forms the inflow water space 201 and the storage water space 202 by combining the first body 210 and the second body 220. In this case, a sealing member 420 is provided between the partition member 420 and the second body 220 so as to completely separate the inflow water space 201 and the storage water space 202 through the partition member 420 It is possible to block the flow of water at the portion excluding the communication opening 425.

The inflow water stabilizing unit 400 may further include a mixing delay plate 410 installed in the inflow space 201 and impacted by inflow water introduced through the inflow unit 230.

The mixing delay plate 410 functions to prevent the water from entering the water storage space 202 immediately when water flows into the water inflow space 201 formed by the partition member 420. In particular, the mixing delay plate 410 functions to reduce the flow velocity of the inflow water when the inflow water is first introduced into the mixing delay plate 410.

At this time, the mixing delay plate 410 is formed such that the central portion located below the inlet 231 of the inlet portion 230 has a downwardly bent 'V' shape so as to fall into the mixing delay plate 410 It can function to temporarily block inflows.

As described above, the inflow water space 201 and the water storage space 202 generate a flow of water through the communication opening 425 of the partition member 420. 6 and 7, the water inlet 231 provided in the water inlet portion 230 and the communication opening (not shown) provided in the water inlet portion 230 are formed so as to prevent the water flowing through the water inlet 231 from flowing out immediately through the communication opening 425. [ 425 are preferably positioned opposite to each other with respect to the thickness direction of the tank body 200.

A communication opening 425 is provided at the upper end of the inflow space 201, that is, at the upper end of the partition member 420, in order to prevent the water introduced into the inflow space 201 from being discharged directly through the communication opening 425 . In this way, by providing the communication opening 425 at the upper end of the partition member 420, the inflow water can be supplied from the lower side to the storage water space 202 beyond the tea-oil communication opening 425.

As described above, when the buffer space 235 is formed in the water inlet 230 or the inlet 231 is formed by a plurality of openings 232, the influent water stabilizing means 400 is supplied with stabilized influent water The influent stabilization effect can be further increased.

Although the partition member 420 is described as being configured to partition the inflow space 201 and the storage water space 202 in the above description, the partition member 420 may be formed at a side other than the communication opening 425 , A portion adjacent to the second body 220} may be opened. In this case, the mixing delay plate 410 delays mixing the inflow water introduced from the water inlet part 230 with the stored water previously stored in the tank body 200, The water passing through the plate 410 is secondarily delayed in mixing with the stored water previously stored in the tank main body 200.

The storage tank 100 according to an embodiment of the present invention may not include the cooling unit 300 as shown in FIG. 3. However, the storage tank 100 shown in FIGS. 1, 2, 4, The cooling unit 300 may be included to cool the water contained in the tank body 200, as shown in FIG. The cooling unit 300 may include the thermoelectric module 310, but is not limited thereto.

2, 7 to 9, a cooling unit 300 using a thermoelectric module 310 includes a thermoelectric module 310, a cold sink (cold block) 330, A sink 340, and a fan 370. Since such a configuration is known in various shapes and structures, a detailed description thereof will be omitted.

The cooling unit 300 includes a cold sink 330 for transferring cool air from the thermoelectric module 310 to the tank main body 200 in order from the outer surface of the tank main body 200, A heat sink 340 including a heat dissipating member 341 and a fan 370 for cooling the heat sink 340 are installed in the heat sink 340. The heat sink 340 is provided at one side of the heat sink 340, And a temperature control switch 380 for sensing whether the fan 370 is driven by sensing the temperature of the fan 340.

A heat insulating member 320 may be installed to cover the cold sink 330 to prevent the heat sink member 330 from being heat-exchanged with the outside. In the center of the heat insulating member 320, as shown in FIG. 2, The assembly opening 321 can be formed so that the cold sink 330 can be installed. The fastening hole 332 of the cold sink 330 is provided to the second body 220 of the tank body 200 and the fastening hole 333 of the heat sink 340 And is coupled to the fastening hole 342 through a fastening member so that the cold sink 330, the thermoelectric module 310, and the heat sink 340 are coupled to each other.

2, 7 and 8, the cooling unit 300 includes a heat conduction member 360 provided inside the tank body 200 and the heat conduction member 360 to the second body 220, And a connecting member 350 for attaching the connecting member 350. [

The thermal conductive member 360 may be formed of a metal having a high thermal conductivity so as to provide cooling water (cold heat) from the cold sink 330 in contact with the thermoelectric module 310 to water contained in the tank main body 200 . At this time, the heat conduction member 360 may be made of stainless steel which is resistant to corrosion and does not pollute water, but is not limited thereto.

The connecting member 350 connects the heat conductive member 360 with the cold sink 330 outside the tank body 200. In order to connect the heat conduction member 360 to the cold sink 330 through the tank body 200, the heat sink 360 is inserted through the tank body 200 from the cold sink 330 to the connection member 350 A fastening member needs to be used. If such a fastening member is exposed to the water contained in the tank body 200, corrosion may occur. Therefore, it is preferable that the coupling portion of the coupling member 350, to which the coupling member is coupled, is formed of a non-penetrating groove so that the coupling member is not exposed to the outside of the coupling member 350.

When the tank body 200 includes the first body 210 and the second body 220, the cooling unit 300 may be attached to the second body 220 made of a metal.

At this time, the second body 220 may be formed of a metal material such as stainless steel which is resistant to corrosion. For example, the inside (the inner surface of the tank body) is made of stainless steel which is resistant to corrosion, and the outside (the inner surface of the tank main body) May be formed of aluminum or copper having excellent thermal conductivity.

In addition, the first body 210 may be formed of a synthetic resin material to efficiently block heat exchange through the first body 210, thereby maximizing a heat insulation effect. Particularly, by making the first body 210 relatively larger than the second body 220, the heat transfer effect through the second body 220 and the heat insulation effect through the first body 210 can be enhanced .

When the first body 210 is made of a synthetic resin, a complex shape can be easily manufactured, so that it is possible to easily form various constitutions such as the influent water stabilizing means 400 and the like.

With this arrangement, even if the inflow water flowing into the storage water space 202 moves downward, the cooling water can be sufficiently cooled by the cooling unit 300, so that the temperature of the water to be delivered can be lowered.

7 and 8, when the heat conduction member 360 is installed inside the tank body 200, the communication opening 425 of the partition member 420 is positioned on the upper side of the heat conduction member 360 So that the inflow water is brought into contact with the heat conduction member 360 through the communication opening 425.
