In general, drinking water treated with purified water is produced by a method such as filtration or adsorption using a filter.

Conventional water purifiers are largely classified into filter type and distillation type. The filter type water purifier has a function of removing substances causing turbidity and color, but it can not remove synthetic detergent, pesticide, chemical materials and the like. In order to be effective, it has to be replaced at an appropriate time, and there is a disadvantage that the water flows through the filter and the bacteria multiply.

In addition, the distillable water purifier is water-vaporized to remove all the impurities, and then is condensed again and reduced to water. Thus, the distilled water is odorless, tasteless, colorless, and does not contain any solid or oil or mineral.

This distillation is a water purification method which can remove most pollutants from water, but there is a disadvantage that excessive energy is consumed in the distillation and cooling of water.

In this way, conventionally, only one of the two methods has been used so as to use final purified water. However, recently, an icemaking system has been added to suppress the growth of bacteria in the filter-type water purifier and to satisfy the convenience of the user.

The present invention relates to a distillation unit (10) for heating supply water supplied from the outside to convert it into water vapor and cooling the water vapor to make condensed water; A ice making part (20) for ice making the condensed water flowing from the distillation part (10) to make ice; A pump unit (30) for allowing condensate produced from the distillation unit (10) to flow to the ice making unit (20); A heat exchanging part 40 which is used in common in the distillation part 10 and the ice making part 20 so that the supply water or steam flowing in the distillation part 10 and the refrigerant flowing in the ice making part 20 exchange heat with each other, ; A storage part 50 for storing the ice made in the ice making part 20 and the ice made by the distillation part 10; And a control unit (not shown) for controlling the distillation unit 10, the ice making unit 20, the pump unit 30, the heat exchanging unit 40, and the storage unit 50.

The distillation section 10 includes a distillation tank 12 having a water supply control means 11 for controlling the supply amount of the feed water and a heating means 14 for heating the introduced feed water to convert it into steam, A flow switching means 15 for controlling the flow of water vapor discharged from the tank 12 and a condensing tank 16 for storing condensed water in which water vapor discharged from the distillation tank 12 is cooled and liquefied.

The water supply control means 11 is provided to regulate the amount of water supplied into the distillation unit 10 along the water supply line a from the outside, and various devices for controlling the water supply may be used, In this embodiment, a solenoid valve is used.

The distillation tank 12 is supplied with the supply water supplied through the water supply control means 11, and converts the supply water into water vapor while heating the purified water. The distillation tank 12 includes heating means 14 for heating the feed water, pressure regulating means (not shown) for regulating the internal pressure, overheat preventing means (not shown) for regulating the internal temperature, And a water level sensor 13 for sensing the stored water level of the water level sensor.

The heating means 14 heats the feed water to convert it into steam. The pressure adjusting means increases the pressure inside the distillation tank 12 by the steam converted by the heating means 14 to a predetermined value or higher The water vapor is discharged to the outside so that the internal pressure of the distillation tank 12 is maintained at a certain level. The heating means 14 can use the condenser 22 of the ice-making section 20 to be described later as an auxiliary means.

When the temperature inside the distillation tank (12) becomes higher than a predetermined value by the heating means (14), the overheat prevention means stops power supply to the heating means (14) .

The water level sensor 13 senses the level of the supply water supplied into the distillation tank 12 and transmits a signal to the control unit when the water level is higher than a predetermined value, The supply of water can be stopped. If it is less than a predetermined value, the signal is transmitted to the control unit, and the control unit can open the water supply control means 11 to supply the supply water continuously.

The flow switching means 15 switches the path of the water vapor discharged from the distillation tank 12 to the condensing tank 16 along the vapor line b according to the level of the ice water stored in the storage portion 50 And various devices may be used, but three sides are used in this embodiment.

That is, when the water level of the ice water stored in the storage unit 50 is equal to or greater than a predetermined level, the steam switching unit 15 switches the water vapor discharged from the distillation tank 12 to the condensation tank 16 So that the water vapor discharged from the distillation tank 12 is circulated to the storage unit 50 and the condensed water is circulated in the condensing tank 50. When the water level of the ice water stored in the storage unit 50 is lower than the predetermined level, 16) so that ice is thawed to make ice water.

The condensing tank 16 is cooled while steam and water vapor passing through the flow switching means 15 flow through the vapor line b to store the condensed condensed water and the first pump 31 is connected to one side .

The condensation tank 16 is provided with a water level sensor 17 on one side like the distillation tank 12. The water level sensor 17 senses the level of the condensed water flowing from the distillation tank 12 and stores it When the water level is equal to or greater than a predetermined value, the signal is sent to the control unit to prevent the water supply control unit 11 from supplying water to the evaporator 23, ) To continue watering.

The condensing water is supplied to the compressor (21), the condenser (22), the refrigerant expansion means and the evaporator (23), the compressor 21 is evaporated in the evaporator 23 by the change in temperature.

The compressor (21) discharges the refrigerant in a gaseous state to a high-temperature and high-pressure state, and the condenser (22) condenses the high-temperature and high-pressure refrigerant discharged from the compressor (21) into a liquefied refrigerant in a low- .

In the condenser 22, the refrigerant in a liquefied state at a low temperature and a high pressure passes again through the refrigerant expansion means and enters a low-temperature and low-pressure state and flows into the evaporator 23. In this embodiment, the refrigerant expansion means comprises a capillary or an expansion valve . The condenser 22 can assist the heating means 14 of the distillation tank 12 by using the phenomenon of raising the ambient temperature while keeping the refrigerant at a low temperature and a low pressure as described above.

The liquefied refrigerant in the evaporator 23 is vaporized again. Since the vaporization of the refrigerant deprives the external heat and lowers the ambient temperature, the condensed water flowing into the evaporator 23 is allowed to be de-iced.

That is, as the liquefied refrigerant in the evaporator 23 and the water outside the evaporator are heat-exchanged, the heat of the condensed water is transferred to the liquefied refrigerant to evaporate the liquefied refrigerant. Since the evaporation temperature of the refrigerant is below the freezing point, As the condensation occurs repeatedly, the condensate is lowered to a temperature below the freezing point to be de-iced.

The refrigerant vaporized by passing through the evaporator 23 flows into the compressor 21 again by the suction action of the compressor 21.

The third heat exchanger 43 cools the water vapor by allowing heat exchange between water vapor discharged without being completely condensed in the condensing tank 16 and refrigerant flowing from the evaporator 23 to the compressor 21 The refrigerant gas which is not vaporized in the vaporized refrigerant gas passing through the evaporator 23 is heated to completely convert it into refrigerant gas so that the refrigerant flowing into the compressor 21 To a complete gas state.

During the operation of the ice-amount sensor 52, the operation of the ice-making part 20 is stopped to allow accurate detection.

That is, if the amount of ice stored in the ice storage tank 51 is equal to or more than a predetermined value, the controller sends a signal to the control unit to stop the operation of the second pump 32 to prevent the condensed water from moving, And sends a signal to the control unit to cause the control unit to start the operation of the second pump 32 to move the condensed water.

The ice water storage tank 53 is provided with a water level sensor 54 at one side where the ice of the ice storage tank 51 stores ice water thawed by water vapor discharged from the distillation tank 12.

The water level sensor 54 senses the level of the ice water stored in the ice water storage tank 53 so that the flow switching means 15 of the distillation unit 10 can control the flow of water vapor discharged from the distillation tank 12 .

That is, if the water level sensor 54 sends a signal to the control unit when the water level of the ice water in the ice water storage tank 53 is equal to or more than a predetermined value, the flow switching unit 15 directly supplies the water vapor discharged from the distillation tank 12 to the condensation tank 16 If the water level of the ice water in the ice water storage tank 53 is below a predetermined value, the flow switching means 15 sends a signal to the control unit so that the water vapor discharged from the distillation tank 12 flows to the ice storage tank 51 side .

[

When the internal pressure of the distillation tank 12 becomes higher than a predetermined value, the steam is discharged to the outside by the pressure regulating means to regulate the pressure. When the internal temperature becomes higher than a predetermined value, The power of the heating means is cut off by the means to stop the heating of the supplied water.

Water vapor is discharged from the distillation tank 12 and flows into the condensing tank 16. When the level of the ice water stored in the ice storage tank 53 during the flow to the condensing tank 16 is lower than a predetermined value, The control unit sends a signal to the control unit to cause the flow switching unit 15 to send the water vapor to the ice storage tank 51 so that the water vapor is heat-exchanged with the ice so that a part of the water vapor condenses and thaws the ice.

When the level of the ice water stored in the ice water storage tank 53 is equal to or greater than a predetermined value, the water level sensor 54 senses the level of the ice water and sends a signal to the control unit.
