Description

[0001] APPARATUS FOR SUPPLYING FUNCTIONAL WATER [0002]

The present invention relates to a functional water supply device, and more particularly, to a functional water supply device capable of providing carbonated water as well as cold water and hot water, and capable of preventing freezing of cold water and carbonated water.

Generally, a cold / warm water purifier cleans water supplied from a separate water tank or a faucet, and the purified water is cooled or heated to a predetermined temperature to provide water at a user-desired temperature. In recent years, due to water pollution and user's convenience, the cold / warm water purifier has been widely used in homes, companies, and public places.

In the United States and Europe, it is common to drink carbonated water at home. The carbonated water is either sold to the customer in a separate container or manufactured directly at home by a domestic carbonated water generator.

In recent years, a product has been introduced that adds a function of supplying carbonated water to a cold / warm water purifier that supplies cold water and hot water. In the conventional cold / warm water purifier capable of producing carbonated water as described above, a cooling device is disposed around the outer periphery of the carbonated water storage container and the cold water storage container to cool the carbonated water and the cold water. Therefore, in the conventional cold / warm water purifier, since the cooling devices are separately installed in the storage containers of the carbonated water and the cold water, the manufacturing cost can be increased, the manufacturing process can be complicated, and the size of the product can be increased.

On the other hand, recently, a technique of cooling a storage container of carbonated water and cold water by using a single cooling device has also been developed. For example, in Korean Patent Laid-Open No. 10-2010-0055991 (titled invention: water supply device, filed on November 18, 2008, published on May 28, 2010), a water supply for easily supplying carbonated water Device is disclosed. As shown in FIG. 2, the cooling device is formed in a structure using one cooling device, and the refrigerant coil of the cooling device is branched into two in the middle and wound in the cold water tank and the carbonated water tank, respectively. Thereby, the cold water tank and the carbonated water tank can be cooled simultaneously by using one compressor, a condenser and an expander.

Since the cooling structure is a structure for cooling the cold water tank and the carbonated water tank separately at different positions, the cooling coil must be branched into two, and the branched cooling coils are wound around the cold water tank and the carbonated water tank, . Therefore, the amount of use of the cooling coil is increased, and the branching portion of the cooling coil and the like are not actually used for cooling.

In recent years, in order to increase the cooling efficiency and production efficiency of the cold water, a technique has been developed in which the flow path of the cold water is spirally formed inside the storage container of the cold water. For example, Korean Registered Utility Model No. 20-0323013 (entitled Cooling Water Storage Tank of Cold and Hot Water Purifier Using Multi-Stage Separation Plate, filed on May 2, 2003, published on Aug. 14, 2003) discloses a multi- So that the water is continuously cooled while flowing along the spiral flow path.

Since the cooling structure has a structure in which water is continuously cooled, the cooling efficiency and production amount of cold water can be increased. However, if the cold water is not extracted to the outside for a long time, there is a high possibility that the water is subcooled, whereby the water is frozen in the flow path, and the flow path is blocked by ice.

The embodiment of the present invention provides a functional water supply device which can reduce both the installation space of the cold water supply module and the car- bonating module and the size of the cooling module by integrally forming the cold water supply module and the car- bonating module.

In addition, the embodiment of the present invention provides a functional water supply device capable of improving the cooling efficiency and manufacturing efficiency of cold water by forming a spiral cold water flow path inside the cold water supply module.

In addition, in the embodiment of the present invention, a de-frost module for removing ice is disposed inside the cold water supply module or the car- bonating module to actively prevent clogging of the flow path due to excessive cooling of cold water and carbonated water Supply device.

Further, the embodiment of the present invention provides a functional water supply device capable of arranging all or a part of the carbonated module in a dual structure inside the cold water supply module.

Also, the embodiment of the present invention provides a functional water supply device that can easily perform cleaning or maintenance of the car- bonating module and the cold water supply module by easily separating the car- bonating module and the cold water supply module.

According to an embodiment of the present invention, there is provided a cold water supply system including a cold water supply module for supplying cold water, a car- bonating module provided in the cold water supply module for heat exchange with the cold water and generating carbonated water by receiving the cold water, A cold water supply module provided inside the cold water supply module to form a spiral cold water flow path inside the cold water supply module, And a cold water defrost module provided in the cold water guide module for providing heat to the cold water guide module and the cold water so that the cold water flow path is not blocked by freezing of the cold water.

Accordingly, in one embodiment of the present invention, the cold water stored in the cold water supply module together with the cooling module can be used to cool the car- bonating module, thereby substantially reducing the cooling load of the cooling module . In addition, in an embodiment of the present invention, it is possible to prevent the freezing of the cold water by using the heat of the cold water defrost module, thereby preventing the cold water flow path from being clogged by freezing of the cold water.

According to one aspect of the present invention, an inlet port for introducing outside water may be formed at one side of the cold water supply module, and an outlet port for discharging the cold water to the outside may be formed at the other side of the cold water supply module. The cold water guide module includes a guide rod provided inside the cold water supply module so as to be arranged to be extended from the inlet to the outlet, and a spiral guide member having a spiral shape on the outer periphery of the guide rod, And a flow guide formed in a wing shape.

The cold water defrost module may be arranged to be received in the guide rod.

The guide rod may be formed in a pipe structure in which a hollow portion for receiving the cold water defrosting module is formed. One end of the guide rod may be formed in a sealed shape to prevent the inflow of the cold water and may be disposed inside the cold water supply module, and the other end of the guide rod may have a shape opened to allow insertion of the cold water defrost module And may be disposed outside the cold water supply module.

The cold water supply module may include a cold water flow rate sensor for sensing a discharge amount of the cold water, and the cooling module may include a cold water temperature sensor mounted on the cold water supply module to detect the temperature of the cold water. The cold water defrost module may be configured to be operated by a sensed value of at least one of the cold water flow rate sensor and the cold water temperature sensor.

According to one aspect, the cold water guide module and a portion of the cold water defrost module may extend to the car- bonating module to provide heat to the car- bonating module.

The car- bonating module may have an insertion hole or an insertion groove for inserting the cold water guide module and the extension of the cold water de-frost module.

According to an aspect of the present invention, a functional water supply device according to an embodiment of the present invention includes a carbonic acid water dispost module provided inside the car- boninating module to provide heat to the carbonic acid water to prevent sub- .

The carbonating module may include a carbonated water temperature sensor provided in the carbonating car- bonating unit to detect the temperature of the carbonated water. The carbonated water distro module may be configured to control the operation according to the sensed value of the carbonated water temperature sensor.

According to one aspect, the car- bonating module may be disposed inside the cold water supply module to be submerged in cold water stored in the cold water supply module. Accordingly, the cold water supply module and the car- bonating module can be integrated to reduce the overall size, and the cooling water stored in the cold water supply module can be used to cool the car- bonating module.

According to one aspect of the present invention, the car- bonating module may be disposed on one side of the cold water supply module such that a part thereof contacts the cold water stored in the cold water supply module. Accordingly, the installation space can be reduced by reducing the size of the cold water supply module and the car- bonating module, and the part of the car- bonating module can be cooled using the cold water stored in the cold water supply module.

The cold water supply module may include a cold water tank in which cold water is generated and stored to be surrounded by the cooling module and a cold water discharge unit connected to the cold water tank to discharge the cold water in the cold water tank to the outside . Here, the cold water discharge unit may be formed to pass through the car- bonating module.

A clearance may be formed between the carbonated water tank and the cold water tank for the presence of the cold water.

According to one aspect, the car- bonating module may be disposed at one side of the cold water supply module so as to be in heat-transfer contact with the cold water supply module.

The functional water supply device according to the embodiment of the present invention may be arranged such that the car- bonating module is closely attached to one side of the cold water supply module or all or a part of the car- bonating module is disposed inside the cold water supply module . Accordingly, the entire size of the cold water supply module and the car- bonating module can be minimized, so that the installation space of the cold water supply module and the car- bonating module and the size of the cooling module can be reduced, thereby realizing miniaturization of the functional water supply device.

In addition, since the functional water supply device according to the embodiment of the present invention is formed in a structure in which at least a part of the car- bonating module is in contact with the cold water of the cold water supply module, The cooling efficiency of the carbonated water and the cooling rate can be improved.

In the functional water supply device according to the embodiment of the present invention, the cold water guide module is disposed inside the cold water supply module to form a spiral cold water flow path, so that the cold water is not mixed with the water introduced from the outside, And the cooling module can continuously cool the cold water flowing along the cold water flow path. Therefore, in this embodiment, the cooling efficiency and the production amount of the cold water can be increased, and the production time of the cold water can be shortened.

Further, since the function water supply device according to the embodiment of the present invention has a structure in which the cold water defrost module is disposed inside the cold water guide module, the cold water defrost module can prevent the clogging of the cold water flow path due to freezing of cold water The phenomenon can be prevented. Particularly, when one end of the cold water deodorization module is extended toward the insertion hole portion or the insertion groove portion of the car- bonating module, it is possible to simultaneously prevent freezing of carbonated water by using the heat of the cold water de- frost module.

In addition, the functional water supply device according to the embodiment of the present invention has a structure in which the carbonated water diffroster module is disposed in the car- bonating module, so that the freezing de- The phenomenon can be prevented.

In addition, the functional water supply device according to the embodiment of the present invention may be formed into a cap shape so that the car- bonating module can be easily coupled to or separated from the penetration portion of the cold water supply module. Therefore, cleaning and maintenance of the car- bonating module and the cold water supply module can be performed easily.

FIG. 1 is a schematic view of a functional water supply apparatus 100 according to an embodiment of the present invention, and FIGS. 2 to 4 are a front view showing a main part of the functional water supply apparatus 100 shown in FIG. 1 An exploded view and a plan view. 6 is a perspective view showing a tank cover 121b of the carbonated water tank 121 shown in FIG. 5, and FIG. 7 is a perspective view showing the tank cover 121b shown in FIG. A cold water guide module 160 and a cold water de-frost module 170. FIG.

1, a functional water supply apparatus 100 according to an embodiment of the present invention includes a cold water supply module 110, a car- bonating module 120, a cooling module 130, a hot water supply module 140, A water supply module 150, a cold water guide module 160, and a cold water defrost module 170.

In the following description, the functional water supply device 100 supplies cold water (CW), hot water (HW) and carbonated water (SW) , Or a combination of mineral water and carbonated water (SW).

Referring to FIG. 1, the cold water supply module 110 is configured to supply cold water (CW) to the outside. For example, the cold water supply module 110 may include a cold water tank 112 and a cold water discharge portion 114.

The cold water tank 112 is a container for generating and storing cold water (CW). That is, cold water (CW) can be generated in the cold water tank 112 due to the cooling action of the cooling module 130, and the generated cold water (CW) can be stored in the inside of the cold water tank 112 The cooling function of the cooling module 130 can be maintained at a low temperature state. Here, the cold water tank 112 may be formed with an inlet port 112a through which water is introduced from the outside and an outlet port 112b through which the cold water CW is discharged to the outside. In the following description, it is assumed that the inlet 112a is formed in the lower portion of the cold water tank 112 and the outlet 112b is formed in the upper portion of the cold water tank 112 in the present embodiment.

The cold water discharge unit 114 is configured to discharge cold water (CW) in the cold water tank 112 to an external user. Therefore, the cold water discharge unit 114 can be connected to the cold water tank 112 in a communicative manner. For example, the cold water discharge portion 114 may include a cold water discharge line 114b and a cold water discharge valve 114a.

The cold water discharge line 114b is a cold water discharge passage through which the cold water CW in the cold water tank 112 flows to the cold water discharge valve 114a. One end of the cold water discharge line 114b may be connected to the outlet 112b of the cold water tank 112 and the other end of the cold water discharge line 114a may be connected to the cold water discharge valve 114a. The cold water discharge line 114b may be formed to pass through the carbonation module 120. Therefore, a leakage preventing structure can be applied to the penetrating portion of the cold water discharge line 114b. When the cold water discharge line 114b is formed so as to pass through the cabonetting module 120, the cold water discharge line 114b is not drawn out to the outside through the side portion of the cold water tank 112, And the cold water discharge line 114b can be prevented and the external exposure of the cold water discharge line 114b can be minimized to prevent the temperature rise during the discharge of the cold water CW. In addition, the cooling module 130 can also be disposed at the maximum density on the side portion of the cold water tank 112 without being disturbed by the cold water discharge line 114b, whereby the cold water (CW) can be cooled more efficiently .

The cold water discharge valve 114a can selectively discharge the cold water CW flowing through the cold water discharge line 114b to the outside. Therefore, the cold water discharge valve 114a can be formed in a structure that is opened and closed by a user's direct operation.

On the other hand, the cold water discharge unit 114 is connected to the cold water discharge line 114b for real-time measurement of the discharge amount of the cold water pump or the cold water (CW) provided on the cold water discharge line 114b to forcibly pump the cold water (CW) And a cold water flow rate sensor 114c provided on the cooling water flow sensor 114c. In the following description, the cold water flow sensor 114c is provided at the end of the cold water discharge line 114b connected to the cold water discharge valve 114a.

Referring to FIGS. 1 to 6, the car- bonating module 120 is configured to supply carbonated water (SW) to a user. In the following description, it is assumed that the car- bonating module 120 generates carbonated water (SW) by using the cold water (CW) of the cold water supply module 110. The carbonated water SW may be cooled by the cold water (CW) of the cooling module 130 and the cold water supply module 110 in a state where the carbonated water SW is stored in the inside of the cabonetting module 120, and may be maintained at a low temperature state.

In this embodiment, the car- bonating module 120 may be disposed on one side of the cold water supply module 110 such that the car- bonating module 120 is partially in contact with the cold water CW stored in the cold water supply module 110. As such, a portion of the car- bonating module 120 may be disposed to be surrounded by cold water stored within the cold water supply module 110. The cold water supply module 110 and the cabonetting module 120 can be reduced in size to reduce the installation space and the cold water stored in the cold water supply module 110 can be used for the carbo The carbonated water in the nating module 120 can be cooled.

The coolant supply module 110 may include a penetration portion 116 through which a portion of the carbonation module 120 may be inserted. In order to prevent leakage between the car- bonating module 120 and the penetrating portion 116, the car- bonating module 120 may be formed as a stopper for shielding the penetrating portion 116. Therefore, the car- bonating module 120 can be smoothly mounted or detached to the through-hole 116 of the cold water supply module 110 and the cleaning and maintenance of the car- bonating module 120 and the cold water supply module 110 Maintenance can also be carried out easily.

For example, the carbonation module 120 may include a carbonated water tank 121, a cold water supply unit 122, a carbon dioxide gas supply unit 126, and a carbonated water discharge unit 124.

The carbonated water tank 121 is a container for generating and storing carbonated water (SW). In the following description, the lower part of the carbonated water tank 121 is inserted into the penetration part 116 formed in the upper part of the cold water tank 112 in the present embodiment. That is, the lower part of the carbonated water tank 121 can be inserted into the cold water tank 112 through the penetration part 116, and the upper part of the carbonated water tank 121 can cover the penetration part 314 And may be coupled to the upper portion of the cold water tank 112. Therefore, the carbonated water tank 121 and the cold water tank 112 can be coupled to each other by a dual tank structure in which two cylindrical tanks are arranged in the inner side and the outer side. In this case, the carbonated water tank 121 is connected to the cold water tank 112 And may be formed in a cylindrical structure having a small diameter.

Alternatively, the penetrating portion 116 may be formed on a lower portion or a side portion of the cold water tank 112 of the cold water supply module 110. In this embodiment, since the water is supplied from the external water source to the lower portion of the cold water supply module 110, the structure in which the penetration portion 116 is formed in the lower part of the cold water supply module 110 is introduced into the cold water tank 112 There is a possibility that the cooling effect of the carbonated water (SW) is lowered by the contact between the water and the carbonated water (SW). In this embodiment, the cooling module 130 is disposed so as to surround the outer periphery of the cold water supply module 110, so that the structure in which the penetration portion 116 is formed on the side surface of the cold water supply module 110 is a cooling module 130 may be substantially reduced to lower the cooling performance of the cold water supply module 110.

The cold water supply unit 122 supplies cold water (CW) to the inside of the carbonated water tank 121. The cold water supply unit 122 may be provided between the carbonated water tank 121 and the cold water discharge unit 114. For example, the cold water supply unit 122 may include a cold water supply line 122a, a cold water supply valve 122b, and a cold water supply pump 122c.

Here, the cold water supply line 122a is a cold water transfer path formed between the carbonated water tank 121 and the cold water discharge unit 114. One end of the cold water supply line 122a may be connected to the carbonated water tank 121 and the other end of the cold water supply line 122a may be connected to the cold water discharge line 114b.

The cold water supply valve 122b opens and closes the cold water supply line 122a. The cold water supply valve 122b may be provided on the cold water supply line 122a. The cold water supply valve 122b may be an electrically controllable solenoid valve.

The cold water supply pump 122c is configured to pump cold water in the cold water supply line 122a when the cold water supply valve 122b is opened. The cold water supply pump 122c may be disposed on the cold water supply line 122a. The cold water supply pump 122c can be actuated when the cold water supply valve 122b is opened and can be stopped when the cold water supply valve 122b is closed.

The carbonic acid gas supply unit 126 supplies the carbonic acid gas to the inside of the carbonated water tank 121 during the production of the carbonated water (SW). For example, the carbonic acid gas supply unit 126 may include a carbonic acid gas supply tank 126a and a carbonic acid gas supply line 126b. The carbonic acid gas supply tank 126a can compress and store high-pressure carbonic acid gas. One end of the carbonic acid gas supply line 126b may be connected to the carbonic acid gas supply tank 126a and the other end of the carbonic acid gas supply line 126b may be connected to the carbonic acid water tank 121. [ Therefore, the carbonic acid gas in the carbonic acid gas supply tank 126a can be supplied into the carbonated water tank 121 along the carbonic acid gas supply line 126b.

Here, check valves 123 and 127 may be disposed in the carbonic acid gas supply line 126b and the cold water supply line 122a, respectively. That is, the check valves 123 and 127 can prevent the carbonic acid gas in the carbonated water tank 121 from flowing back to the carbonic acid gas supply line 126b and the cold water supply line 122a.

The carbonated water discharging portion 124 is configured to discharge carbonated water (SW) in the carbonated water tank 121 to an external user. The carbonated water discharge unit 124 may be connected to the carbonated water tank 121 in a communicative manner. For example, the carbonated water discharge portion 124 may include a carbonated water discharge line 124b and a carbonated water discharge valve 124a.

The carbonated water discharge line 124b is a carbonated water discharge passage through which the carbonated water SW in the carbonated water tank 121 flows to the carbonated water discharge valve 124a. One end of the carbonated water discharge line 124b may be connected to the carbonated water tank 121 and the other end of the carbonated water discharge line 124b may be connected to the carbonated water discharge valve 124a. The carbonated water discharge valve 124a can selectively discharge the carbonated water SW flowing through the carbonated water discharge line 124b to the outside. The carbonated water discharge valve 124a may be formed in a structure that is opened or closed by a user's direct operation.

As shown in FIGS. 1 to 6, in this embodiment, the carboarding module 120 is further described as having a water level sensor 128. The water level sensor 128 detects the water level of the carbonated water SW stored in the carbonated water tank 121. Therefore, the operation of the cold water supply unit 122 and the carbon dioxide gas supply unit 126 can be appropriately controlled according to the water level detection value of the water level detection sensor 128. [ For example, the water level sensor 128 may be composed of at least one of a float sensor and an electrode sensor, but the present invention is not limited thereto, and various sensor structures capable of sensing the level of the cold water can be applied.

2 to 6, the detailed structure and connection relationship of the carbonated water tank 121 according to the present embodiment will be described in detail as follows.

2 to 6, the carbonated water tank 121 may include a tank body 121a and a tank cover 121b.

The tank body 121a may be formed in a cylindrical shape for generating and storing carbonated water (SW). The tank body 121a may be inserted through the penetration portion 116 and thereby be disposed inside the cold water tank 112. [ Therefore, the tank main body 121a may be formed in a cylindrical shape having a diameter smaller than that of the cold water tank 112. An opening (not shown) through which the tank cover 121b is mounted may be formed on the upper surface of the tank body 121a.

The tank cover 121b may be formed in a shape that simultaneously shields the opening portion of the tank body 121a and the penetration portion 116 of the cold water tank 112. [ The tank cover 121b can be mounted or detached together on the upper part of the tank main body 121a and the upper part of the cold water tank 112. [ Here, the tank cover 121b can be fastened to the tank body 121a and the upper portion of the cold water tank 112 with fastening members. The tank cover 121b may be formed to have a larger size than the upper portion of the cold water tank 112 so as to cover the upper portion of the cold water tank 112 together with the tank main body 121a of the carbonated water tank 121. [

Here, the tank cover 121b may be provided with a packing member 121c. The packing member 121c is configured to prevent leakage of carbonated water (SW), cold water (CW), and carbon dioxide gas through the opening portion and the penetration portion (116). For example, the packing member 121c may be formed of a ring-shaped rubber packing disposed on the lower surface of the tank cover 121b.

A cold water discharge line 114b, a cold water supply line 122a, a carbonic acid gas supply line 126b, a carbonated water discharge line 124b, a water level sensor 128, The carbonic acid water distro module 180 and the carbonic acid water temperature sensor 182 may be arranged to pass through. The carbonic acid gas supply line 126b may be connected to the pipe member 121d formed to penetrate the tank cover 121b and the water level sensor 128 may be disposed inside the pipe member 121d. Accordingly, the carbonic acid gas supply line 126b and the water level sensor 128 can be installed in a compact structure.

In addition, the tank cover 121b may be provided with a partition plate 121e for partitioning the internal space of the tank body 121a. The partition plate 121e may be formed to protrude downward from the lower surface of the tank cover 121b. The protruding length of the partition plate 121e may be such that the lower surface of the tank body 121a and the lower surface of the partition plate 121e can be separated from each other when the tank cover 121b and the tank body 121a are coupled have. The inner space of the tank main body 121a can be partitioned into the first space S1 and the second space S2 by the partition plate 121e. The first space S1 is a space for placing the cold water supply line 122a, the carbonated water distro module 180 and the carbonated water temperature sensor 182. The second space S2 is a space for placing the carbonated water discharge line 124b, A discharge line 114b, a carbon dioxide gas supply line 126b, a pipe member 121d, and a water level sensor 128 are disposed. Therefore, the phenomenon that the cold water (CW) supplied to the cold water supply line 122a is discharged directly through the carbonated water discharge line 124b can be prevented. More specifically, the cold water CW can be supplied to the first space S1 through the cold water supply line 122a, and after the cold water CW is supplied to the first space S1, Carbonated water (SW) can be produced while mixing. The carbonated water SW in the first space S1 can then flow into the second space S2 through the space formed between the lower part of the partition plate 121e and the bottom surface of the tank body 121a, The carbonated water SW in the second space S2 can be discharged to the outside through the carbonated water discharge line 124b.

1, 3 and 5, a gap G may be formed between the carbonated water tank 121 and the cold water tank 112 in which the cold water stored in the cold water tank 112 is disposed. That is, the tank main body 121a of the carbonated water tank 121 can be disposed in a state in which it is not in close contact with the inner side surface of the cold water tank 112, whereby the cold water tank 112 is disposed between the cold water tank 112 and the tank main body 121a. (CW) may be introduced. Therefore, the side portion and the lower portion of the tank main body 121a may be surrounded by cold water (CW) stored in the cold water tank 112. [ The bottom surface and the side surface of the tank main body 121a may be in contact with the cold water CW of the cold water tank 112 in a heat exchangeable manner and the carbonated water SW stored in the tank main body 121a may contact the tank main body 121a To the cold water (CW) of the cold water tank (112). The cold water tank 112 and the carbonated water tank 121 may be formed of a material having excellent heat transfer performance so that the cooling efficiency of the cold water CW stored in the cold water tank 112 and the carbonated water stored in the carbonated water tank 121 The cooling efficiency of the switch SW can be improved.

At least one of the cold water tank 112 and the carbonated water tank 121 may be provided with a gap forming part 121f for forming the gap G to a predetermined size. The gap forming portion 121f may serve to form and maintain a gap G between the cold water tank 112 and the carbonated water tank 121. In addition, the gap forming portion 121f may also serve to stably support the side portion of the carbonated water tank 121 in the cold water tank 112.

For example, the gap forming portion 121f may be formed in a protruding shape on at least one side of at least one of the cold water tank 112 and the carbonated water tank 121. The protrusion height of the gap forming portion 121f may be a gap G, As shown in FIG. Alternatively, the gap forming portion 121f may be formed of a spacer attached to a side surface portion of at least one of the cold water tank 112 and the carbonated water tank 121. The thickness of the gap forming portion 121f is a gap G, As shown in FIG. Hereinafter, in the present embodiment, the gap forming portion 121f may be formed so that the gap forming portion 121f continuously protrudes at a predetermined height along the circumference of the side surface of the tank main body 121a for the convenience of explanation. The upper portion of the side surface of the tank main body 121a is described as being bent step by step in the direction of expanding the diameter, but the present invention is not limited thereto and may be variously changed according to the design conditions and conditions of the functional water supply device 100. [

1, the cooling module 130 is configured to generate and maintain the cold water (CW) of the cold water supply module 110 and the carbonated water (SW) of the car- bonating module 120 at a set temperature or lower. The cooling module 130 may be disposed outside the cold water supply module 110 and the car- bonating module 120. Hereinafter, in the present embodiment, the cooling module 130 is arranged to surround the outer periphery of the cold water supply module 110.

The cooling module 130 may be configured to cool the cold water supply module 110 more than the car- bonating module 120. This is because the cold water supply module 110 generally has a larger cooling load than the carbonated module 120. That is, in the cold water supply module 110, cold water (CW) is generated by cooling water at room temperature, but carbonated water (SW) is generated in the carbonating module 120 by reacting cold cold water (CW) with carbon dioxide gas. Therefore, the cooling load of the cold water supply module 110 using water at room temperature can be higher than that of the car- bonating module 120 using cold water (CW).

For example, the cooling module 130 may include a compressor (not shown) for compressing the refrigerant, a condenser (not shown) for condensing the refrigerant compressed in the compressor, an expander (not shown) for expanding the refrigerant condensed in the condenser, And an evaporator for evaporating the refrigerant expanded in the expander and then guiding the refrigerant to the compressor. Here, the evaporator may include a cooling pipe 132 through which the flow of refrigerant and evaporation take place. The cooling pipe 132 may be spirally wound around the outer surface of the cold water tank 112. The cooling pipe 132 may be tightly closed at a higher density than the upper portion of the outer surface of the cold water tank 112 where the carbonated water tank 121 is inserted. Therefore, the cooling pipe 132 of the cooling module 130 can cool the cold water (CW) of the cold water tank 112 more effectively than the carbonated water (SW) of the carbonated water tank 121.

The cooling module 130 according to the present embodiment may further include a cold water temperature sensor 134 and a controller 136. The cold water temperature sensor 134 may be provided inside the cold water tank 112 to measure the temperature of the cold water CW stored in the cold water tank 112 in real time. The control unit 136 can appropriately control the operation of the cooling module 130 according to not only the detection value of the cold water temperature sensor 134 but also the detection value of the carbonated water temperature sensor 182 described later.

Referring to FIG. 1, the hot water supply module 140 supplies hot water (HW) to an external user. For example, the hot water supply module 140 may include a hot water tank 142, a hot water outlet 144, and an auxiliary tank 146.

The hot water tank 142 is a container for generating and storing hot water (HW). A heater (not shown) for heating water may be provided inside the hot water tank 142. Therefore, in the hot water tank 142, the heater can generate hot water HW by heating the water stored in the hot water tank 142, or can maintain the hot water HW at a high temperature.

The hot water discharge unit 144 is configured to discharge the hot water HW in the hot water tank 142 to an external user. The hot water discharge unit 144 may be connected to the hot water tank 142 in a communicative manner. For example, the hot water discharge portion 144 may include a hot water discharge line 144b and a hot water discharge valve 144a. The hot water discharge line 144b is a hot water discharge passage through which the hot water HW in the hot water tank 142 flows to the hot water discharge valve 144a. One end of the hot water discharge line 144b may be connected to the hot water tank 142 and the other end of the hot water discharge line 144b may be connected to the hot water discharge valve 144a. The hot water discharge valve 144a can selectively discharge the hot water HW flowing through the hot water discharge line 144b to the outside. Therefore, the hot water discharge valve 144a can be formed in a structure that is opened and closed by a user's direct operation.

The auxiliary tank 146 is a structure for compensating for the sudden pressure increase in the hot water tank 142. The auxiliary tank 146 may be provided to communicate with one side of the hot water tank 142 and may have a relatively small size as compared with the hot water tank 142. Therefore, when the internal pressure of the hot water tank 142 is increased to the set pressure or higher in the operation of the hot water supply module 140, the high temperature steam generated in the hot water tank 142 flows into the auxiliary tank 146 . If the auxiliary tank 146 is not installed in the hot water tank 142, there is a danger that the hot water tank 142 will explode if the internal pressure of the hot water tank 142 is increased beyond the set pressure.

Referring to FIG. 1, the water supply module 150 is configured to supply water from the external water source W1 to the hot water supply module 140 and the cold water supply module 110 at a set pressure. For example, the water supply module 150 may include first water supply units 151, 152, 153, 154, 155 and second water supply units 156, 157.

The first water supply units 151, 152, 153, 154, and 155 are configured to supply water to the cold water tank 112 of the cold water supply module 110. The first water supply units 151, 152, 153, 154, and 155 may be formed to communicate between the cold water tank 112 and the external water source W1. For example, the first water supply units 151, 152, 153, 154 and 155 include a first water supply line 151, a first water supply line 151, and a second water supply line 151 formed between the cold water tank 112 and the water source W1, A purifying filter 152 disposed on the first water supply line 151 for purifying the water supplied through the first water supply line 151 and a second water supply line 151 disposed on the first water supply line 151 for opening and closing the first water supply line 151, A water supply valve 155 and a pressure regulating mechanism 154 disposed on the first water supply line 151 to regulate the pressure of water passing through the first water supply line 151.

Hereinafter, in the present embodiment, it is assumed that the external water source W1 is tap water that supplies water at a predetermined pressure. The purifying filter 152 is configured to remove foreign substances and bacteria contained in tap water, and various filters may be used according to design conditions. The first water supply valve 155 may be a solenoid valve that can be controlled electrically. The pressure adjusting mechanism 154 may be configured as a pressure reducing valve for appropriately reducing the pressure of the tap water, but may be configured to be omitted or pressurized depending on the pressure condition of the water source W1 and the surrounding conditions. On the other hand, a check valve 153 may be disposed in the first water supply line 151 to prevent the cold water in the cold water tank 112 from flowing back to the first water supply line 151.

On the other hand, the water of the water storage tank may be used as the external water source. In this case, since there is no water pressure unlike the case where the external water source W1 is tap water, a pump for providing the supply pressure of the cold water CW, the hot water HW and the carbonated water SH can be additionally provided.

The second water supply units 156 and 157 are configured to supply water to the hot water tank 142 of the hot water supply module 140. The second water supply units 156 and 157 may be connected between the hot water supply module 140 and the first water supply units 151, 152, 153, 154 and 155. For example, the second water supply units 156 and 157 include a second water supply line 156 formed between the hot water tank 142 of the hot water supply module 140 and the first water supply line 151, And a second water supply valve 157 disposed on the second water supply line 156 to open and close the line 156. One end of the second water supply line 156 may be connected to the previous first water supply line 151 of the first water supply valve 155 and the other end of the second water supply line 156 may be connected to the hot water tank 142 have. The second water supply valve 157 may be constituted by an electrically controllable solenoid valve. The first water supply line 151 and the second water supply line 156 may have drain portions 158 and 159 for draining water to the outside.

Meanwhile, a bypass line 156a may be formed in the first water supply line 151 and the second water supply line 156. The bypass line 156a is a path for bypassing the water in the first water supply line 151 to the second water supply line 156. [ One end of the bypass line 156a may be connected to a subsequent first water supply line 151 of the first water supply valve 155 and the other end of the bypass line 156a may be connected to a downstream end of the second water supply valve 157 And may be connected to the second water supply line 156. A bypass valve 156b may be provided on the bypass line 156a. The bypass valve 156b can selectively control the flow of water through the bypass line 156a.

Referring to FIGS. 1 to 5 and 7, the cold water guide module 160 may form a cold water flow path F in which cold water (CW) flows in the cold water supply module 110. The cold water guide module 160 may be received in the cold water supply module 110. The cold water flow path F may be spirally formed inside the cold water supply module 110 from the inlet 112a toward the outlet 112b.

For example, the cold water guide module 160 may include a guide rod 162 and a flow guide 164.

The guide rods 162 may be provided inside the cold water supply module 110 so as to be long from the inlet 112a toward the outlet 112b. For example, in the present embodiment, the guide rod 162 may be formed to be long in a straight line, and may be vertically arranged in the vertical direction inside the cold water supply module 110. The upper end of the guide rod 162 may be located inside the cold water supply module 110 and the lower end of the guide rod 162 may be located outside the cold water supply module 110. That is, the lower end of the guide rod 162 may be disposed to pass through the lower portion of the cold water supply module 110.

Here, the guide rod 162 may be formed in a pipe structure in which the hollow portion is formed, and the cold water defrost module 170 may be inserted into the hollow portion of the guide rod 162. The upper end of the guide rod 162 may be disposed inside the cold water tank 112 and may be formed in a sealed shape to prevent the inflow of the cold water CW. The lower end of the guide rod 162 may be disposed outside the cold water tank 112 and may be formed in an opened shape to allow insertion of the cold water de-frost module 170. Therefore, the cold water de-frost module 170 can be inserted into the hollow portion formed inside the guide rod 162 through the lower end portion of the guide rod 162.

The flow guide 164 can form a cold water flow path F in a spiral shape along the longitudinal direction of the guide rod 162. For example, the flow guide 164 may be formed as a spiral wing at the outer periphery of the guide rod 162 so as to flow water spirally from the inlet 112a toward the outlet 112b. That is, the water introduced into the inlet 112a can be circulated to the outlet 112b while being spiraled by the flow guide 164, and can be cooled by the cooling module 130 in the process. Therefore, the flow guide 164 can extend the length of the path through which the water flows in the cold water tank 112, thereby sufficiently securing the cooling time by the cooling module 130, Water can be sequentially flowed along the cold water flow path F without mixing with each other, thereby increasing the production efficiency of the cold water (CW).

1 to 5 and 7, the cold water defrosting module 170 is a device for preventing clogging of the cold water flow path F due to freezing of cold water (CW). For example, the cold water de-frost module 170 may include a heater section 172 and a power supply section 174. [

The heater unit 172 may be formed of a cold water guide module 160 and an electric heater that provides heat to the cold water (CW). In the following description, it is assumed that the heater unit 172 is formed of a silicon heater, but the present invention is not limited thereto. Various types of heaters may be used depending on the design conditions and conditions of the functional water supply device 100. The heater portion 172 may be disposed inside the hollow portion of the guide rod 162 of the cold water guide module 160. For example, the heater unit 172 may be disposed at an upper end of the cold water guide module 160, and the cold water guide module 160 and the heater unit 172 may be in close contact with each other to secure thermal conductivity.

The power supply unit 174 may be provided between the heater unit 172 and the external power supply to supply external power to the heater unit 172. [ The power supply unit 174 may be disposed outside the hollow portion of the guide rod 162 of the cold water guide module 160. For example, the power supply unit 174 may be disposed at a lower end of the cold water guide module 160, and the power supply unit 174 may be connected to an external power source through a wire (not shown).

As shown in FIGS. 1 and 5, ice (I) may be generated to a predetermined thickness by the cooling module 130 on the inner peripheral surface of the cold water tank 112. Therefore, the water introduced into the inlet port 112a can be quickly cooled by the contact with the ice (I) in the process of flowing along the cold water flow path (F). The ice (I) of the cold water flow path F may be thicker from the inlet 112a to the outlet 112b. This is because the temperature of the water flowing into the inlet 112a is higher than the temperature of the cold water CW discharged to the outlet 112b.

However, when the cooling module 130 is operated for a long time without withdrawing the cold water CW, the thickness of the ice I is continuously thickened by the cooling module 130, and the passage of the cold water flow path F may be blocked. In addition, since the discharge space D formed between the cold water guide module 160 and the carbonated water tank 121 in the cold water tank 112 communicates with the outlet 112b, the temperature of the cold water CW Since it is the coldest part, the freezing phenomenon of the cold water (CW) easily occurs and the freezing point of the cold water (CW) may clog the outlet 112b.

In this embodiment, the cold water defrosting module 170 can provide heat to the inside of the cold water tank 112. Therefore, it is possible to prevent the thickness of the ice (I) formed on the inner peripheral portion of the cold water tank 112 from becoming thicker than the set value, thereby blocking the cold water flow path F from clogging. In addition, even in the discharge space D formed between the cold water guide module 160 and the carbonated water tank 121, the freezing phenomenon of the cold water CW is prevented to prevent the outflow opening 112b from being clogged with the ice I . Accordingly, the cold water defrosting module 170 can actively secure the production efficiency and the production amount of the cold water (CW) produced by the cold water supply module 110.

In the present embodiment, the discharge amount of the cold water (CW) can be measured in real time through the cold water flow rate sensor 114c provided in the cold water discharge part 114 of the cold water supply module 110, The current temperature of the cold water CW can be measured in real time through the cold water temperature sensor 134 provided in the cold water tank 112 of the controller. Accordingly, the operation of the cold water de-storm module 170 can be appropriately selected depending on the sensed value of at least one of the cold water flow rate sensor 114c and the cold water temperature sensor 134. [

For example, if the current discharge amount of the cold water (CW) sensed by the cold water flow sensor 114c is smaller than the set discharge amount, it can be determined that the cold water flow path F is blocked by the freezing action of the cold water (CW) The cold water de-frost module 170 can be operated to melt the ice (I) on the cold water flow path (F). If the present temperature of the cold water CW sensed by the cold water flow sensor 114c is lower than the set temperature range, it can be determined that the cold water CW is overcooled, and accordingly, the cold water defrost module 170 is operated So that the temperature of the cold water (CW) can be appropriately adjusted.

1 to 6, the functional water supply apparatus 100 according to an embodiment of the present invention may further include a carbonated water distro module 180 for preventing subcooling or freezing of carbonated water (SW) . The carbonated water dispost module 180 may be provided in the carbonated water tank 121 to supply the carbonated water SW stored in the carbonated water tank 121. For example, the carbonated water distro module 180 may include a carbonated water heater 184 for providing heat to the carbonated water (SW) like the cold water guide module 160. The carbonated water heater 184 may be disposed to pass through the central portion of the tank cover 121b and may be connected to an external power source through an electric wire (not shown). In the following description, it is assumed that the carbonated water heater 184 is formed of a silicon heater. However, the present invention is not limited to this, and various types of heaters may be used depending on the design conditions and conditions of the functional water supply device 100.

Meanwhile, the present temperature of the carbonated water (SW) can be measured in real time through the carbonated water temperature sensor 182 provided in the tank cover 121b of the carbonating module 120. The operation of the carbonated water defroster module 180 can be appropriately controlled in accordance with the detection value of the carbonated water temperature sensor 182.

The operation of the functional water supply device 100 according to the embodiment of the present invention will now be described.

First, the cold water supply process of the functional water supply device 100 will be described. The first water supply valve 155 is opened, the second water supply valve 157 is closed, and the cooling module 130 is operated. The water of the water source W1 enters the inlet 112a of the cold water tank 112 through the purifying filter 152 and the pressure adjusting mechanism 154. [ At this time, the purifying filter 152 can purify the water, and the pressure regulating mechanism 154 can appropriately adjust the pressure of the water.

The water flowing into the cold water tank 112 may be circulated to the outlet 112b while being spirally rotated along the cold water flow path F formed by the cold water guide module 160. [ When the water flowing into the inlet 112a flows along the cold water flow path F, the water can be cooled by the cooling module 130 and at the same time, the ice I formed on the inner circumferential surface of the cold water tank 112, Can be cooled by direct contact with water. The generated cold water CW is discharged to the cold water discharge line 114b through the outlet 112b.

If the cold water discharge valve 114a is opened, the cold water CW in the cold water tank 112 flows along the cold water discharge line 114b and is discharged to the external user through the cold water discharge valve 114a. At this time, the cold water flow rate sensor 114c measures the amount of cold water (CW) discharged to the cold water discharge valve 114a in real time.

In the hot water supply process of the functional water supply device 100, the first water supply valve 155 is closed, the second water supply valve 157 is opened, and the heater is operated. Then, the water of the water source W1 enters the hot water tank 142 through the purifying filter 152 and the pressure adjusting mechanism 154. [ At this time, the purifying filter 152 can purify the water, and the pressure regulating mechanism 154 can appropriately adjust the pressure of the water.

The water flowing into the hot water tank 142 is heated by the heater and then discharged to the hot water discharge line 124b. At this time, the water in the hot water tank 142 is heated by the heater to a set temperature or higher.

If the hot water discharge valve 124a is open, the hot water HW in the hot water tank 142 flows along the hot water discharge line 124b and is discharged to the external user through the hot water discharge valve 124a.

Lastly, the carbonated water supply process of the functional water supply device 100 will be described. First, a sufficient amount of cold water (CW) is secured by the cold water supply module 110. If it is determined that the cold water CW is insufficient, the first water supply valve 155 is closed, the second water supply valve 157 is closed, and the cooling module 130 is operated as in the cold water supply process described above. As a result, cold water (CW) is generated and stored in the cold water tank 112 as in the cold water supply process.

When the cold water (CW) is sufficiently secured as described above, the cold water discharge valve 114a is closed, the cold water supply valve 122b is opened, and the cold water supply pump 122c is operated. At this time, the cold water supply pump 122c pumps the cold water (CW) in the cold water tank 112 to the carbonated water tank 121. Accordingly, the cold water CW in the cold water tank 112 flows along the cold water discharge line 114b, and then is supplied to the carbonated water tank 121 through the cold water supply line 122a.

In this state, when the carbonic acid gas supply unit 126 supplies carbon dioxide gas to the inside of the carbonated water tank 121, the cold water CW supplied to the inside of the carbonated water tank 121 reacts with carbon dioxide gas to be formed of cold carbonated water . At this time, when the carbonated water discharge valve 124a is opened, the carbonated water SW in the carbonated water tank 121 flows along the carbonated water discharge line 124b and is discharged to the external user through the carbonated water discharge valve 124a.

On the other hand, when the functional water supply device 100 according to the present embodiment is used for a long time, if the cold water (CW) is not withdrawn properly, the cold water (CW) or the carbonated water It can be frozen.

For example, if the cold water (CW) or the carbonated water (SW) is subcooled below the proper temperature, the cold water (CW) and the carbonated water (SW) are too cold to drink. When the cold water CW is frozen in the cold water tank 112, the cold water flow path F or the peripheral part of the outlet port 112b may freeze and the cold water CW may not be able to flow and discharge. When the carbonated water SW freezes in the inside of the carbonated water tank 121, the periphery of the inlet of the carbonated water discharge line 124b freezes and the carbonated water SW can not be discharged.

Here, by using the sensed values of the cold water temperature sensor 134 and the cold water flow rate sensor 114c, it is possible to detect whether the cold water (CW) stored in the cold water tank 112 is overcooled or not, It is possible to appropriately determine whether or not the de-frost module 170 is operated. For example, when the sensed value of the cold water temperature sensor 134 is detected to be lower than the set temperature, it is determined that the cold water (CW) is undercooled or frozen to operate the cold water defrost module 170, It is determined that the cold water CW is frozen and the cold water defrost module 170 can be operated.

The heat generated in the heater unit 172 is transmitted to the inside of the cold water tank 112 through the guide rod 162 of the cold water guide module 160 As the temperature of the cold water (CW) rises, the ice (I) frozen in the inner peripheral surface of the cold water tank 112 at a temperature higher than a set value is partially melted. At this time, if the sensed value of the cold water temperature sensor 134 rises above the set temperature, the operation of the cold water de-frost module 170 is stopped.

The detection value of the carbonated water temperature sensor 182 can be used to detect whether the carbonated water SW stored in the carbonated water tank 121 is undercooling or freezing, It is possible to determine appropriately whether it works or not. For example, when the sensed value of the carbonated water temperature sensor 182 is detected to be lower than the preset temperature, it is determined that the carbonated water SW is undercooled or iced, and the carbonated water defrost module 180 can be operated.

When power is applied to the carbonated water deodorization module 180 as described above, the heat generated from the carbonated water heater 184 can be transferred to the inside of the carbonated water tank 121, and the temperature of the carbonated water SW is raised. At this time, when the sensed value of the carbonic acid water temperature sensor 182 rises above the set temperature, the operation of the carbonic acid water distro module 180 is stopped.

FIG. 8 is a diagram showing major parts of a functional water supply device 200 according to another embodiment of the present invention.

In FIG. 8, the same reference numerals as those shown in FIGS. 1 to 6 denote the same members, and a detailed description thereof will be omitted. Hereinafter, the functional water supply device 100 shown in FIG. 1 to FIG.

8, the functional water supply device 200 according to another embodiment of the present invention is different from the functional water supply device 100 shown in FIGS. 1 to 7 in that a cold water guide module 260, There is a difference in that a part of the de-frost module 270 is formed to extend toward the car- bonating module 120, and the carbonated water de-frost module 180 shown in Figs. 1 to 6 is omitted.

That is, in this embodiment, the heat of the cold water defrost module 270 may be provided to the car- bonating module 120 together with the cold water supply module 110, and the cold water (CW) And the carbonated water (SW) can be prevented at the same time. Therefore, unlike the functional water supply apparatus 100 shown in FIGS. 1 to 7, the present embodiment can omit the carbonated water dispost module 180, thereby reducing the number of parts of the functional water supply apparatus 100 So that the manufacturing cost can be reduced.

For example, the upper end of the guide rod 262 of the cold water guide module 260 may be formed with an extended portion 266 extending upward. The heater portion 272 of the cold water de-frost module 270 may be disposed in the extension portion 266 of the guide rod 262. [ The tank body 221a of the carbonated water tank 221 may be formed with an insertion hole portion or an insertion groove portion 222 for inserting the extension of the guide rod 262 and the heater portion 272 into the lower portion of the tank body 221a. In the following description of the present embodiment, an insertion groove 222 is formed below the tank main body 221a of the carbonated water tank 221 for convenience of explanation. However, the present invention is not limited to this, A hole portion may be formed. When the insertion hole portion is formed in the lower portion of the tank main body 221a, the guide rod 262 and the upper end portion of the heater portion 272 are disposed so as to pass through the insertion hole portion, Structure can be installed.

The heater unit 272 according to this embodiment may be formed of a silicon heater in the same manner as the heater unit 272 shown in Figs. 1 to 7. The heater 272 may be disposed on the hollow portion of the guide rod 262 in the longitudinal direction of the guide rod 262.

For example, if the heater portion 272 is formed in a single number, the heat of the heater portion 272 can be simultaneously supplied to the cold water (CW) and the carbonated water (SW). Accordingly, the cold water defrost module 270 can simultaneously remove the cold water (CW) and the carbonated water (SW).

On the other hand, if a plurality of heater sections 272 are provided in the longitudinal direction of the guide rods 262, the operation of the heater sections 272 can be selectively controlled to selectively provide heat according to the position of the guide rods 262 .
