Hereinafter, the operation and effect of the water purifier 1 having the above configuration will be described.

The water purifier 1 may provide one of purified water, high-temperature water, and ultra-high-temperature water to the user based on a mode input by the user.

When the user inputs the water purification mode, raw water flows into the filter unit 10 through the raw water intake passage 31 . In addition, the first valve module 41 closes the purified water intake flow path 32 and opens the purified water output flow path 33 . In this case, purified water filtered by the filter unit 10 is discharged to the outside through the purified water outlet flow path 33 and the water outlet unit 60 .

When the user inputs the hot water dispensing mode, the first valve module 41 opens the purified water intake channel 32 and closes the purified water outlet channel 33 . The purified water filtered by the filter unit 10 is introduced into the heating body 100 through the purified water intake flow path 32 and the inlet 110. In addition, in the hot water dispensing mode, the surface heating heater 200 heats purified water to hot water. In this case, the sheath heater 300 does not operate in the hot water dispensing mode. In other words, in the high-temperature water dispensing mode, purified water in the heating body 100 is heated to a predetermined temperature only by the surface heating heater 200 .

Meanwhile, when the hot water dispensing mode is repeatedly input by the user at predetermined time intervals, the second valve module 42 opens the drain passage 35 after the hot water dispensing mode is input until the next hot water dispensing mode is input. do. In this case, gas vaporized inside the heating body 100 may be drained to the outside through the drain passage 35 . For example, when a predetermined amount of hot water is discharged in the hot water discharge mode, the drain passage 35 may be opened for a preset drain time. In addition, when the hot water dispensing mode is input again within the drain time from the time when the hot water is dispensed in a predetermined amount, the hot water can be dispensed with the drain passage 35 open. In other words, if the hot water dispensing mode is repeatedly input at intervals shorter than the drain time, the hot water can be simultaneously discharged through the water dispensing unit 60 while the gas is drained to the outside through the drain passage 35 .

In addition, when the temperature of the hot water measured by the first sensor 51 exceeds the preset first hot water temperature while the purified water is being heated in the hot water dispensing mode, the power supply unit 70 is transmitted to the surface heating heater 200 power can be reduced. For example, the first hot water temperature may be 99° C., and when the temperature of the hot water measured by the first sensor 51 exceeds 99° C., the power supply unit 70 transfers the temperature to the surface heating heater 200. power can be reduced.

Meanwhile, when the user inputs the ultra-high-temperature water dispensing mode, the first valve module 41 opens the purified water intake flow path 32 and closes the purified water output flow path 33. The purified water filtered by the filter unit 10 is introduced into the heating body 100 through the purified water intake flow path 32 and the inlet 110. In addition, in the ultra-high-temperature water extraction mode, the surface heating heater 200 and the sheath heater 300 operate together to heat purified water into ultra-high-temperature water.

When the temperature of the hot water measured by the second sensor 52 exceeds the preset second hot water temperature while the purified water is being heated in the ultra-high temperature water dispensing mode, the power supply unit 70 includes the surface heating heater 200 and the sheath heater ( 300) can be lowered. Here, the second hot water temperature is a temperature set higher than the first hot water temperature. For example, the second hot water temperature may be 101 ° C., and when the temperature of the hot water measured by the second sensor 52 exceeds 101 ° C., the power supply unit 70 uses the surface heating heater 200 and the sheath heater Power delivered to 300 may be lowered.

As such, the heating device 20 according to an embodiment of the present invention arranges the surface heating heater 200 and the sheath heater 300 in one heating body 100 to heat purified water in a short time to obtain high temperature water or It has the effect of providing ultra-high temperature water. In this case, the number of heating bodies 100 providing a space in which water is heated is reduced to minimize the volume, and there is an effect that a miniaturized water purifier 1 can be provided.

In addition, the heating device 20 can prevent the planar heating heater 200 from being burst by bubbles by adjusting power so that the planar heating heater 200 does not heat purified water to 100 ° C. or more. In addition, by disposing the planar heating heater 200 and the sheath heater 300 so as to be spaced apart from each other by a predetermined distance, there is an effect of preventing the planar heating heater 200 from bursting due to bubbles vaporized in the sheath heater 300.

On the other hand, by disposing the sheath heater 300 closer to the discharge part 120 than the planar heating heater 200, the sheath heater 300 heats the high temperature water primarily heated in the planar heating heater 200, thereby improving power efficiency. There is an effect that can be maximized.

In addition, when the hot water dispensing mode is repeatedly input, the gas is drained through the drain passage 35, so that when the hot water is dispensed, there is an effect that the hot water can be discharged stably without being shaken by bubbles.
