DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a hot water temperature automatic control system and method according to preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a hot water temperature automatic control system according to a preferred embodiment of the present invention. The cold water pipe 10, the hot water pipe 20, the hot water supply control unit 30, the temperature sensing unit 40, (50) and a water discharger (60).

The cold water pipe (10) means a pipe to which cold water is supplied, and the hot water pipe (20) means a pipe to which hot water is supplied.

The temperature sensing unit 40 serves to detect the temperature of the supplied hot water, and it is preferable to use a normal temperature sensor. It is preferable that the temperature sensing unit 40 is provided at a predetermined position of the hot water pipe to which the hot water is supplied.

The hot water supply controller 30 adjusts the temperature of the hot water according to the output signal of the temperature sensor 40, and supplies the hot water. Preferably, the hot water supply control unit 30 selectively supplies cold water or hot water mixed with hot water or cold water according to an output signal of the temperature sensing unit 40. The hot water supply controller 30 may include a controller for generating an open / close control signal in accordance with an output signal of the temperature sensor 40, and an electromagnetic valve for controlling opening and closing of the hot water under the control of the controller.

The hot water supply control unit 30 supplies the hot water supplied according to the output signal of the temperature sensing unit 40 to the temperature control unit 50 as it is or mixes the supplied hot water and cold water, To the temperature control side 50, or to block the supplied hot water, and to supply only the cold water to the temperature control side 50.

The temperature control valve 50 controls the temperature of the hot water supplied from the hot water supply controller 30 and the supplied cold water. These temperature control knobs 50 represent conventional conventional manual temperature control knobs or automatic temperature control knobs.

The water discharger 60 serves to discharge the regulated water through the temperature control valve 50 and means a washstand or a shower.

The operation of the hot water temperature automatic control system according to the present invention will now be described in detail with reference to FIG.

The cold water supplied through the cold water pipe 10 flows into one inlet of the temperature control valve 50 and the hot water controlled by the hot water supply controller 30 is supplied to the other inlet of the temperature control valve 50 .

At this time, the hot water supply control unit 30 supplies hot water to the temperature control side 50 in three types according to the temperature of the hot water detected through the temperature sensing unit 40, and hot water of high temperature is suddenly discharged, Thereby preventing burning of the hot water.

For example, as a first form, the controller compares the hot water detection temperature (t 占 폚) detected from the temperature sensing section (40) with a predetermined reference temperature (T 占 폚) (for example, 50 占 폚) When the hot water detection temperature is higher than the reference temperature, the hot water supplied by controlling the solenoid valve is cut off, and only cold water flowing through the cold water pipe 10 is supplied as hot water. Therefore, cold water flowing through the cold water pipe 10 flows into one inlet of the temperature control valve 50, and cold water supplied from the hot water supply controller 30 flows into the other inlet. In this case, even if the user operates the temperature control knob 50, only the cold water is discharged to the water discharger 60 to prevent hot water from being discharged.

In the second form, the controller compares the hot water detection temperature (t 占 폚) detected from the temperature sensing section (40) with a preset reference temperature (占 폚) (for example, 50 占 폚) When the hot water detection temperature is higher than the reference temperature, hot water supplied by controlling the solenoid valve is mixed with cold water introduced through the cold water pipe 10 to regulate the hot water temperature. Therefore, the cold water flowing through the cold water pipe 10 flows into one inlet of the temperature control valve 50, and the temperature-controlled hot water supplied from the hot water supply controller 30 flows into the other inlet. Thereafter, when the user operates the temperature control knob 50, the water discharger 60 discharges cold water or hot water mixed with cold water and temperature-controlled hot water to prevent hot water from being discharged will be.

In the third form, the controller compares the hot water detection temperature (t 占 폚) detected from the temperature sensing section (40) with a predetermined reference temperature (T 占 폚) (for example, 50 占 폚) When the hot water detection temperature is lower than the reference temperature, the electromagnetic valve is controlled to block the cold water inflow and supply the hot water supplied as it is. Therefore, cold water flowing through the cold water pipe 10 flows into one inlet of the temperature control valve 50, and hot water supplied from the hot water supply controller 30 flows into the other inlet. In this case, since the temperature of the hot water is adjusted to an appropriate temperature at which no image is formed, even if the user operates the temperature control side 50 to the full hot water, hot water adjusted in temperature is discharged to the water discharger 60, Thereby preventing the user from wearing the image.

As shown in FIG. 2, the first embodiment of the automatic hot water temperature control method according to the present invention includes (a) detecting a hot water temperature (S10); (b) comparing the detected hot water temperature with a preset reference temperature (S20); (c) controlling the supply of hot water according to the result of the comparison in the step (b) (S30 to S50).

The first embodiment of the hot water temperature automatic control method according to the present invention will be described in detail as follows.

First, in step S10, the hot water temperature (t DEG C) is detected through the temperature sensing unit 40. [ If it is determined that the detected hot water temperature is higher than the reference temperature, the process proceeds to step S40. In step S40, the hot water temperature (t C) is compared with the reference hot water temperature Thereby adjusting the temperature of the hot water. Thereafter, in step S50, the temperature adjusted water is supplied. If the detected hot water temperature is lower than the reference temperature, the process proceeds to step S30 and the hot water supplied through the hot water pipe is directly supplied as hot water.

FIG. 3 is a flowchart showing a second embodiment of a method for automatically controlling hot water temperature according to the present invention, wherein S represents a step. As shown in FIG. 3, the second embodiment of the automatic hot water temperature control method according to the present invention includes (a) detecting a hot water temperature (S10); (b) comparing the detected hot water temperature with a preset reference temperature (S20); (c) controlling the supply of hot water according to the result of the comparison in the step (b) (S30, S60).

The second embodiment of the hot water temperature automatic control method according to the present invention will be described in detail as follows.

First, in step S10, the hot water temperature (t DEG C) is detected through the temperature sensing unit 40. [ If the detected hot water temperature is higher than the reference temperature, the process proceeds to step S60. In step S60, the hot water temperature (t C) detected in step S20 is compared with the reference temperature And the cold water supplied through the cold water pipe is supplied to the hot water pipe. That is, the high-temperature hot water is cut off and the cold water is supplied to the hot water pipe instead, thereby preventing the burning of the hot water by the hot hot water. If the detected hot water temperature is lower than the reference temperature, the process proceeds to step S30 and the hot water supplied through the hot water pipe is directly supplied as hot water.
