Flow rate is measured by the instantaneous hot water unit 230, the instantaneous cold water unit and the instantaneous hot water unit to supply power to the instantaneous heating in the process of passing through the filtered water whose flow rate is adjusted by the distribution unit, the instant cold water unit When supplying power to the thermoelectric module of 240 is supplied to the power supply unit 271 and the instantaneous cold water unit 240 and the instantaneous hot water unit 230 for converting and supplying an AC current directly to a DC current And a control unit 270 that controls the distribution unit and the applied voltage control to adjust the flow rate of the control unit 270, using the heat generated by the thermoelectric module of the instantaneous cold water unit 240 Control to evaporate the residual water in the flow path.

Accordingly, the instantaneous cooling and instantaneous heating type water purifier 200 according to the present invention supplies a power supply unit 271 that directly converts AC current into DC current when supplying power to the thermoelectric module of the instantaneous cooling water unit 240. It can reduce the volume and weight of water purifiers, increase design flexibility, and reduce manufacturing costs.

That is, since the thermoelectric element is a device driven by a direct current (DC) current, a direct current is required even when driving the thermoelectric module included in the water purifier. However, in general, since the current supplied to a house, office, factory, etc. is an AC current, in order to drive a water purifier including a thermoelectric module using the same, a power supply device capable of converting and supplying an AC current into a DC current is provided. It is necessary.

In addition, since a thermoelectric module including 8 to 12 small thermoelectric elements may be used in the case of a thermoelectric module that may be included in a general water purifier, a power supply capable of supplying a DC current of approximately 1 kW in order to drive a thermoelectric module having this size An apparatus is required, and the power supply of such a capacity is similar in size and weight to a small water purifier, and the price also exceeds the price of a small water purifier, and thus there is a problem in that it is not easy to apply to a general water purifier. However, the water purifier 200 according to the present invention includes a power supply unit 271 having a compact structure for rectifying AC current to a DC current through a bridge diode, thereby solving this problem. .

Here, the allowable voltage that can be applied to the power supply unit 271 is approximately AC 150 to 280V, and may be preferably set to 160 to 250V in consideration of the performance and safety of the water purifier. In addition, the shape and size of the power supply unit 271 is, for example, a plate-shaped hexahedron, the length of the long side of the upper surface and the lower surface is 220 to 260mm, respectively, the length of the short side is 100 to 110mm, respectively, The distance between the lower surface may be made of a hexahedral shape of 30 to 50mm in height. The power supply unit 271 having such a shape and size has excellent space utilization when placed on the inner surface of the water purifier housing.

In addition, the instantaneous cooling and instantaneous heating water purifier 200 according to the present invention, the control unit 270 to evaporate the remaining water in the flow path using the heat generated by the thermoelectric module of the instantaneous cold water unit 240. Since it is controlled, the residual water remaining inside the flow paths is removed by evaporation by heat when the water purifier is not used, thereby maintaining the best water quality of the clean water passing through the filter 250 and providing the user with the best water quality.

In addition, in order to maximize the efficiency of removing the residual water in the flow path by the thermoelectric module of the instantaneous cold water unit 240, the plate-like instantaneous cold water unit 240 is vertical to facilitate heat transfer with respect to the flow paths installed inside the water purifier. You can place it.

On the other hand, the instantaneous cooling and instantaneous heating water purifier 200 according to the present invention is the water heated or cooled by the inlet 291, the instant hot water unit 230 and the instant cold water unit 240 to inject water from the outside It may include a water outlet valve 210 and a water outlet assembly 100 connected to the water outlet valve 210 to the outside.

The instantaneous cooling and instantaneous heating water purifier 200 includes a flow meter 251 on the filter 250 so as to measure the amount of water flowing from the inlet 291 and passing through the filter 250. In addition, a two-way valve 280 may be provided as a distribution unit to selectively control the water discharged from the instant hot water unit 230 and the instant cold water unit 240 to the water discharge valve 210. Can be.

That is, the flow rate of the water measured by the flow meter 251 is controlled by the two-way valve (280) distribution unit is delivered to the instantaneous hot water unit 230 and the instant cold water unit 240.

The drain 292 serves to discharge the cooling water for removing heat generated by the thermoelectric elements included in the cold water unit 240 to the outside when the cold water is generated in the water purifier 200, and the pipes in the water purifier 200, respectively. It discharges the washing water generated after performing the auto-flushing function to clean the components of the whole.

In the case of a general water purifier, as a flushing operation for cleaning a new filter when the water purifier is installed, approximately 10 to 20 liters of water (clean water) is filled with the new filter inside the water purifier and then discharged to the outside to use the new filter. The work to make the state is performed, and a considerable amount of washing water generated at this time is discharged through the outlet where the purified water is discharged. Therefore, the user should receive the waste water directly from the outlet by using a bowl, etc., or dispose of the washing water by connecting a separate waste water tank to collect the washing water with the outlet. It is troublesome to clean the pipe.

However, in the water purifier 200 according to the present invention, the drain hole 292 is connected to a cleaning feed valve for separately supplying and supplying the washing water generated after the cleaning operation, thereby auto-flushing the water purifier 200. The drainage port 292 is formed separately from the outlet 210 through which the purified water is discharged so that the washing water generated after the function is conveniently discharged to the outside, thereby improving user convenience.

In addition, the flow meter 251 measures the amount of washing water used during auto-flushing of the water purifier 200, and recognizes that the washing is normally completed when the required amount of washing water is discharged. If the required amount of washing water is not discharged during cleaning, it is recognized as abnormal termination and the contents are displayed on the front panel of the water purifier 200 through LEDs, thereby making it easy to check whether the water purifying function is completed. The user's convenience can be further improved.

On the other hand, the water purifier 200 includes a power PCB 260, the 2-way valve (280) for controlling the operation of the instant hot water unit 230 and the instant cold water unit 240, and the like. The hot water unit 230 inside the water purifier 200 according to a control PCB 270 that is a control unit for controlling the driving of valves connected to various pipes inside the water purifier and the overall operation of the water purifier 200 and a water purifier user's input signal. , PCBs 221 for various controls such as the touch PCB 221 and the extraction touch PCB 222 which distinguish driving signals of the cold water unit 240, the filter 250, and the various valves and transmit them to the respective components. , 222, 260, and 270.

Figure 3 is a schematic diagram showing the flow of purified water in the water purifier according to an embodiment of the present invention, Figure 4 is a schematic diagram showing the flow of cold water in the water purifier according to an embodiment of the present invention, Figure 5 6 is a schematic diagram showing the flow of hot water in the water purifier according to an embodiment of the present invention, Figure 6 is a schematic diagram showing the flow of washing water in the water purifier according to an embodiment of the present invention.

Referring to these drawings, first, the flow of purified water in the water purifier 200 of the present invention is the feed water flowing through the inlet 291, the feed valve 293, the filter 250, the flow meter 251, the two-way valve 280 After passing through the instantaneous cold water unit 240 and the water outlet valve 210 in sequence, the water is finally discharged through the faucet 211.

In addition, in the water purifier 200 of the present invention, the flow of cold water is divided into feed valve 293 and the radiant water feed valve 294 respectively, which are introduced through the water inlet 291, and the radiant water feed valve 294. The water introduced through is used to cool the instantaneous cold water unit 240, and is discharged through the drain 292, the water introduced through the feed valve 293 is the feed valve 293, the filter 250, The flow meter 251, the two-way valve 280, the instantaneous cold water unit 240, and the water outlet valve 210 are sequentially passed through and finally discharged through the faucet 211.

In addition, the flow of hot water in the water purifier 200 of the present invention is the raw water introduced through the inlet 291, the feed valve 293, the filter 250, the flow meter 251, the two-way valve 280, instantaneous hot water unit ( 230, the water outlet valve 210 is sequentially passed through and finally discharged through the faucet 211.

In addition, the flow of the washing water in the water purifier 200 of the present invention sequentially passes through the feed valve 293, the filter 250, the flow meter 251, the two-way valve 280 through the inlet 291 Then, when cleaning the instant hot water unit 230 and the piping around it is discharged through the instantaneous hot water unit 230 and the cleaning feed valve 212 through the drain 292, the instant cold water unit 240 and When the surrounding pipe is cleaned, it is discharged through the drain port 292 via the instantaneous cold water unit 240 and the cleaning feed valve 212.

That is, the instantaneous cooling and instantaneous heating type water purifier 200 according to the present invention passes through the filter 250 to remove foreign substances, the flow rate is measured by the flow meter 251, the filtering flow rate is adjusted by the distribution unit The purified water is passed through the instantaneous cold water unit 240 or the instantaneous hot water unit 230 to generate cold water or hot water. Therefore, problems such as deformation or abnormality of the filter, which may occur when raw water not filtered by the filter is heated by a hot water unit or the like to pass through the filter, can be prevented.

In general, the use temperature of the filter used in the water purifier is approximately 5 to 35 ℃. However, when unfiltered raw water is heated to a high temperature of 50 ° C. or higher by an instant hot water unit or the like and passes through the filter, the high temperature itself imposes a strain on the filter, causing damage and deformation of the filter. The concentration of foreign substances, etc. contained in the raw water is increased, the movement becomes active to further damage the filter, as well as to increase the scale inside the water purifier flow path, may cause the flow path clogging phenomenon.

However, the instantaneous cooling and instantaneous heating type water purifier 200 according to the present invention removes foreign substances by passing the raw water first through the filter, and measures the flow rate through the flow meter 251 to adjust the flow rate by passing through a valve which is a distribution unit. Then, by passing through the instant hot water unit 230 or the instant cold water unit 240, this problem can be prevented.

The filter 250 filters to remove foreign substances contained in raw water supplied from the outside, and may include a sediment filter, a precarbon filter, a reverse osmosis membrane filter, a post carbon filter, and the like.

Instantaneous hot water unit 230 is disposed in an upright state to provide a heat source to instantaneously heat the water filtered by the filter 250 in the passage, and is a surface heating element including an electrode and a heating element. The instant hot water unit 230 is provided with a hot water inlet valve in the inlet pipe and a hot water extraction valve in the discharge pipe is possible to adjust the hot water discharge of the hot water intake coke.

On the other hand, by providing a drain valve in the connection pipe connecting the discharge line and the radiating water drain line of the instantaneous cold water unit 240 and the instantaneous hot water unit 230 and the filter 250, the flow path is inclined, Residual water in the interior can be discharged naturally.

That is, as a first embodiment to implement this, it is possible to implement a system that automatically removes the water in the flow path when the user does not use the water purifier for any time. The drain valve is placed on the drain side, and the flow path is inclined so that the remaining water is discharged by its own weight. In this case, the control unit 270 controls the control unit 270 to heat weak heat by using the characteristics of the thermoelectric module 340, so that the water formed in the flow path is also evaporated so that the remaining water does not remain.

In a second embodiment, it is also possible to implement a system that removes residual water using the system's latency. In general, in order to extract the temperature of the first cup to the desired temperature in the cold and hot water systems, there is a waiting time of less than 5 seconds. At this time, a large flow rate can be flowed into the hot / cold water unit for a short waiting time (less than 1 second) to push out the remaining water remaining in the flow path first, and then add a function of extracting purified water. In order to remove residual water at the initial flow rate, it is possible to use the water purifier without any inconvenience to users by configuring the system to operate the valve inside the product and flow the water inside the flow path to the drain.

In conclusion, the two embodiments described above for the discharge of residual water in the flow path may implement a system capable of immediately drinking clean water passing through the filter by completely removing the residual water in the flow path by mixing each or two methods.

The power supply unit 271 supplies power to the instantaneous cold water unit 240 and the instantaneous hot water unit 230, and in particular, converts AC current directly into DC current when power is supplied to the thermoelectric module of the instantaneous cold water unit 240. do.

That is, when the first glass of cold water is extracted, the target temperature is adjusted by adjusting the flow rate of the drinking water of the cooling unit and the heating unit or extracting the applied voltage to extract the water of the set temperature (for example, 10 ° C. or less) from the first glass. Water can be extracted or both can be used for control. In the case of direct AC-DC change, if the voltage of input AC is increased, the voltage of output DC also increases proportionally.

Here, the DC current should be supplied to the product due to the characteristics of the thermoelectric module. When the AC current is directly converted into DC, the unit cost of the power supply unit 271 can be significantly lowered. However, at this time, the commercial AC 220V power is converted to a voltage of DC 300V (load 260V) or more to proceed to the configuration adapted to the voltage applied in the configuration and combination of the thermoelectric module. In this case, the thermoelectric module is a product that cannot be used at an alternating current, and a separate power supply unit 271 for AC-DC conversion is required to use the thermoelectric module.

In general, the thermoelectric module uses a voltage of less than 30V, and even in the stage of commercialization, the product is generally configured with a power supply system of 50V or less due to the limitation of the power supply unit 271. As the utility of thermoelectric modules increases, it occurs when a large number of thermoelectric modules are connected to each other and not just a single unit or two to four connections. The problem is the power supply.

First, in the case of supplying power in the conventional manner, if the voltage is set low (less than 50V), the current value is high, and if the current value is high, the products with high allowable current values of various electrical and electronic components must also be used. Second, if the voltage is set high, the existing product does not have a high voltage AC-DC changer, and even if the product is manufactured as necessary, the primary side and the secondary side are insulated in consideration of user safety. It must be made. In this case, there is a problem in that the size of the product increases and the unit price is expensive.

At this time, if the insulation distance for the user's safety is secured at the thermoelectric module side, it can easily solve the problem raised above.

Since the thermoelectric module included in the instantaneous cold water unit 240 of the present invention satisfies the insulation distance criterion at the module stage, the power supply unit does not need to separately insulate the primary side and the secondary side from the power supply unit 271. The size and construction cost of 271 can be significantly lowered. In addition, it is easy to secure the design flexibility of the power supply unit 271 has an advantage that the product development is easy.

The control unit 270 controls the flow rate of the water supplied to the instantaneous cold water unit 240 and the instantaneous hot water unit 230 and the voltage adjustment applied thereto. That is, the control unit 270 controls the current amount and the current application of the thermoelectric module included in the instantaneous cold water unit 240 and at the same time to control the flow rate of the incoming water inlet tube of the instantaneous cold water unit 240 It controls the operation of the automatic valve installed in, and the temperature control of the cold water desired by the user according to the result value of the temperature sensor installed in the discharge pipe of the instantaneous cold water unit 240 enables to control the thermoelectric module and the like.

On the other hand, the control unit 270 may include a power control board (B) that can control the water exit temperature by sensing the temperature of the water outlet valve (210).

The instantaneous cooling and instantaneous heating water purifier 200 according to the present invention through the filter 250, the raw water supplied through the water inlet 291 through the process of precipitation, filtration, sterilization, heavy metals and other harmful substances contained in the raw water The material is removed and purified.

Next, when the user operates the cold water button to drink cold water, the cold water unit 240 operates and cools the raw water passing through the thermoelectric module while draining the cold water through the water outlet valve 210. On the other hand, the heat dissipation surface of the thermoelectric module is cooled by the heat generating module in close contact with the heat dissipation surface.

In contrast, when the user wants to drink hot water, when the hot water button is operated, the hot water unit 230 operates and heats the raw water passing through the inside through the heater, and the hot water is drained through the intake coke.

As a result, since the water purifier 200 operates only when the user operates the intake cock to drink cold water and hot water, noise is not generated when it is not used.

In addition, the water purifier 200 applying the instantaneous cooling and instantaneous heating method of the present invention operates the instantaneous cold water unit 240 or the instantaneous hot water unit 230 only when the user uses the water purifier because hot water or cold water is required.

Referring to these drawings, the instantaneous cold water unit 300 instantaneously thermoelectrically cools the filtered water through the filter 250 in an upright state, and includes a flow path plate 310, a closing plate 320, and a heat transfer plate. 330, a thermoelectric module 340, and a heating module 350. At this time, the instant cold water unit 300 serves to cool the raw water, and in addition to this function can be used to extract the hot water by switching the current direction applied to the thermoelectric module 340.

Here, the instantaneous cold water unit 300 can reduce the area occupied by the product by forming a heat dissipation unit at both sides with a central cooling unit, unlike the conventional cross-sectional module arrangement method, when reducing the size of the instantaneous cold water unit 300 The design flexibility of the finished product is secured, allowing various products to be configured.

On the other hand, the instantaneous cold water unit 300 is referred to as the cooling unit, the configuration of the flow path plate 310, the closing plate 320, the heat transfer plate 330 that is the inside, based on the thermoelectric module 340, the thermoelectric module The configuration of the heating module 350 that is outside of the 340 is called a heating unit.

The flow path plate 310 has inlet pipes 312 and discharge pipes 314 formed on the outer walls, respectively, and semicircular flow paths 316 formed on both side walls thereof. At this time, the inlet pipe 312 and the discharge pipe 314 is preferably provided at both ends of the flow path 316, respectively.

Here, the flow path plate 310 is illustrated that the flow path 316 is formed in the case itself as in this embodiment, but is not limited to this flow path 316 is formed in a separate mechanism and the case is formed on the outer can do. In addition, the flow path 316 may be formed of any one of a metal material such as aluminum or stainless steel, a rubber material such as silicon, or a synthetic resin. In addition, the shape of the flow path 316 may be formed in the shape of a groove or a hollow space.

The closing plate 320 is formed of a silicon material or the like and closely adheres to both sidewalls of the flow path plate 310, and has a semicircular flow path so as to be symmetrically formed in communication with the flow path 316 formed on the outer wall of the flow path plate 310, respectively. 326 are formed in the inner wall, respectively.

In addition, the inlet pipe 312 may be provided with an automatic valve to control the inflow flow rate, the discharge pipe 314 may be provided with a temperature sensor for sensing the temperature of the water discharged.

The heat transfer plate 330 is provided to increase the heat transfer efficiency to the finish plate 320 according to the heat absorption in the thermoelectric module 340 disposed on the outer wall is in close contact with both outer walls of the closing plate 320, respectively. In this case, the heat transfer plate 330 is illustrated as being made of a stainless steel (SUS) material, but is not limited thereto and may be changed to ceramic, aluminum, and high temperature glass.

The heat transfer plate 330 may lead to breakage of the module when an imbalance of force is made when assembling due to the characteristics of the thermoelectric module 340, which is made of ceramic, so as to solve the problem, the inside of the heat transfer plate 330 is based on the thermoelectric module 340. When the size of the cooling unit and the heating unit plates, which are the outer and outer components, are configured in the same size as the module, the damage of the module can be reduced.

A plurality of thermoelectric modules 340 are in close contact with both outer walls of the heat transfer plate 330, and when power is applied, absorbs heat at one junction and radiates heat at the other junction according to the Peltier effect. Here, the thermoelectric module is an environmentally friendly energy material capable of converting thermal energy and electrical energy. The p-type and n-type thermoelectric semiconductors in the form of chips are electrically mounted in series with a ceramic substrate such as alumina interposed therebetween. have. In particular, when electrical energy is applied to the thermoelectric module, the charges (electrons, holes) inside the thermoelectric semiconductor absorb the thermal energy at one end of the thermoelectric module and move to the opposite side. As a result, one side of the thermoelectric module is cooled and the opposite side is Fever occurs. In this case, the thermoelectric module 340 is in close contact with each of the outer walls of the heat transfer plate 330, respectively, the heat dissipation surface is in close contact with the heat generating module 350 to be described later.

On the other hand, the thermoelectric module 340 can implement a structure that secures an insulation space (Creepage) with the N-type and P-type elements on the upper, lower electrode outer surface to secure the insulating space in the module power supply unit ( 271) Flexibility in design can be achieved.

In addition to the bolt fastening method, the thermoelectric module 340 is bonded to the contact surface between the heat transfer plate 330 and the heat generating module 350 in close contact with the surface of the closing plate 320 by a glue, and then integrated. It may be fixed to the portion and the heating portion side closing plate 320, respectively.

The heat generating module 350 may be in close contact with the rear surface of the thermoelectric module 340 to cool the heat dissipating surface of the thermoelectric module 340 by a water cooling method or an air cooling method. In this case, the heat generating module 350 includes a water jacket in the case of a water cooling method, and a heat sink and a fan in the case of an air cooling method.

At this time, when the heat generating module 350 is a water cooling method, the instantaneous cold water radiating water control valve may be provided in a tube provided to supply the radiating water to the water jacket. In addition, the inlet valve may be further provided to adjust the pressure of the radiant water supplied by the instantaneous cold water radiant water control valve to improve heat dissipation efficiency.

On the other hand, when the heat generating module 350 is a water-cooling method, a flow path is formed to allow the cold water to flow therein, and the cold water inlet pipe and the cold water discharge pipe communicate with each other. At this time, although the flow path is formed in the heat generating module 350 through direct processing, in the case of direct processing, the processing cost is high, which leads to an increase in the unit cost of the product. Therefore, precision using aluminum die casting or lost wax method is used to solve this problem. The cost can be reduced by using a casting method.

The heating module 350 may further include a safety device in which a physical safety device such as bimetal or the like and a sensor and a circuit such as a thermocouple or thermistor (NTC, PTC) are combined.

The flow path plate 310 ′ and the closing plate 320 generally have a structure in which only the edge and the center or the edge of the plate are bolted in consideration of the position of the module. In this case, if the flow path 316 of the flow path plate 310 and the flow path 326 of the closing plate 320 do not maintain rigidity more than a certain length, a bending phenomenon may occur, resulting in breakage or degradation of the thermoelectric module 340. It can be cause. Of course, the assembly process can be solved through careful attention of the operator and proper torque (torque) adjustment, but the work maneuver and the fatigue of the operator is a cause of increase. In order to solve this problem, a reinforcement frame 360 having holes 318 formed on only the flow path 316 of the flow path plate 310 may be added to make a structure in which an even force is distributed on the entire surface of the flow path. In this case, it is possible to free the deflection of the flow path itself.
