Fig. 3 is a block diagram of an embodiment of the controller of Fig. 2; Fig.

Hereinafter, a water saving system of a boiler according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a configuration diagram of a water saving system of a boiler according to a preferred embodiment of the present invention. The boiler 10 includes a boiler 10, a hot water pipe 20, a direct water pipe 30, a water receiver 40, a hot water circulation pipe 50, A circulation pump 70, a check valve 80, a warm-up button 90,

The hot water pipe 20 serves to transfer the hot water supplied from the boiler 10 to the power receiver 40 side.

The direct water pipe (30) serves to supply direct water to the power receiver (40) and the boiler (10). In this case, the water pipe and the water pipe for supplying direct water to the boiler are denoted by the same reference numerals, but the direct water pipe connected to the water faucet 40 and the water pipe connected to the boiler 10 are different, And the same reference numerals are given to them.

The water receiver 40 may be a four-way valve that discharges hot water or cold water or hot water + cold water or bypasses the remaining water of the hot water pipe 20 according to a user's operation.

The warm water circulation pipe 50 circulates the residual water bypassed in the water receiver 40 to the boiler 10 side and the preheating button 90 prevents water from being wasted, And to input a preheating signal for preheating.

When the user judges that preheating is required for using hot water, the user operates the preheating button 90 and uses hot water after a predetermined time. It is preferable that the preheating button 90 is always turned on as needed so that the hot water can be discharged at any time when the water supply is operated.

The sensor unit 60 measures the temperature and flow rate of the hot water in the hot water circulation pipe 50 for circulating the hot water. The sensor unit 60 includes a water temperature sensor for measuring the temperature of the hot water circulated in the hot water circulation pipe 50, And a flow rate sensor for measuring the flow rate of the hot water circulated in the hot water circulation pipe (50).

When the preheating signal is inputted, the controller 100 controls the residual water circulation and the hot water heating of the boiler according to the hot water temperature and the flow rate measured by the sensor unit 60, so that the residual water remaining in the hot water pipe It always keeps it at constant temperature.

The controller 100 includes a preheating signal input unit 101 for receiving a preheating signal generated during operation of the preheating button 90, a flow rate input unit 102 for receiving a flow rate signal generated in the sensor unit 60, A water saving control unit 104 for controlling the preheating of residual water based on the preheating signal, the flow rate signal, and the detection temperature to perform water saving, A circulation pump driving unit 105 for driving the circulation pump 70 in accordance with the circulating pump driving signal to be outputted, a valve driving unit 106 for driving the check valve 80 according to the valve control signal output from the water saving control unit 104, . Here, the water saving control unit 104 preferably compares the detected temperature with the set temperature set through the boiler, and controls the preheating according to the difference.

The check valve 80 is installed in a hot water circulation pipe 50 provided between the boiler 10 and the water receiver 40 under the control of the controller 100 to circulate the hot water to the boiler 10 Thereby preventing the hot water from flowing into the boiler 10.

The circulation pump 70 functions to circulate hot water of the hot water circulation pipe 50 under the control of the controller 100.

The operation of the thus constructed boiler water saving system according to the present invention will be described in detail as follows.

First, the user operates the preheat button 90 to the on state before using the hot water or always using hot water.

The hot water supplied from the boiler 10 is supplied to the faucet 40 through the hot water pipe 20 when the faucet 40 is operated in a state where the preheating button 90 is not turned on, Is mixed with the direct water supplied through the direct water pipe (30) according to the level, and is discharged to the power receiver (40). At this time, the initial hot water discharged through the faucet (40) is mixed with remaining water and direct water remaining in the hot water pipe (20). If the boiler (10) is not operated for a long time, Even if you want, hot water will not be discharged and cold water will come out. Therefore, a user who wants to use hot water throws out the initial discharged water, and when hot water having a certain temperature is raised, water is used at that time. Therefore, water is wasted.

When the preheating button 90 is turned on to prevent water waste and save water, a preheating signal is input to the controller 100. The preheating signal input unit 101 of the controller 100 receives the input preheating signal and transmits it to the water saving controller 104. The water saving control unit 104 detects the flow rate and the temperature of the hot water in the hot water circulation pipe 50 when the preheating signal is input.

For example, the sensor unit 60 installed at a predetermined position of the hot water circulation pipe 50 detects the flow rate flowing through the hot water circulation pipe 50 by using the flow rate sensor and transmits the detected flow rate to the controller 100, And transmits the detected temperature to the controller (100).

The flow rate input unit 102 of the controller 100 receives the flow rate signal detected by the flow rate sensor and transmits the flow rate signal to the water saving control unit 104. The temperature input unit 103 receives the temperature signal detected by the water temperature sensor And transmits it to the water saving controller 104.

The water saving controller 104 determines whether or not the hot water is preheated based on the input flow rate and the hot water temperature. That is, the detected hot water temperature is compared with a predetermined set temperature. If the detected hot water temperature is lower than the set temperature, preheating is determined. If the detected hot water temperature is higher than the set temperature, non-preheating is determined. Here, the set temperature is a preset temperature in software or a preset temperature received from the boiler 10.

In the case of non-preheating, a special operation is not performed, and the operation of continuously detecting the flow rate and detecting the temperature of the water is performed and the operation is compared with the set temperature.

When the preheating is determined, the heating signal is transmitted to the boiler 10 to heat the hot water. At the same time, the circulating pump driving signal is transmitted to the circulating pump driving unit 105, and the valve driving signal is transmitted to the valve driving unit 106 do.

The boiler 10 operates the heater according to the transmitted heating signal, performs a heat exchange operation to heat the circulating hot water, and discharges the heated hot water to the hot water pipe 20. The valve driving unit 106 operates the check valve 80 so that hot water is circulated and the circulating pump driving unit 105 drives the circulation pump 70 to cool the hot water pipe 20 and the hot water circulation pipe 50 Thereby circulating hot water. Here, the drive amount of the circulation pump 105 and the opening amount of the check valve 80 are preferably adjusted based on the detected flow rate.

When the preheating button 90 is operated, the preheating operation is performed while circulating the remaining water and hot water remaining in the hot water pipe 20 through the preheating operation. During the preheating operation, the sensor unit 60 continuously detects the flow rate and the temperature of the hot water, and based on this, the water saving controller 104 controls the heating, the circulation pump, and the check valve.

When the hot water circulated during the preheating operation reaches the set temperature, the hot water circulation and the preheating operation are terminated. When the hot water is again lower than the set temperature, the preheating operation and the hot water circulating operation are performed again.

By this operation, the user preheats the hot water to the desired temperature at all times before operating the faucet 40. The preheating operation is continuously performed as long as the preheating button 90 is operated in the ON state.

Then, when the user operates the water receiver 40 to the hot water to use hot water, hot water heated to an appropriate temperature is directly discharged to the water receiver 40 through the hot water pipe 20, and the user immediately uses hot water . As a result, it is possible to eliminate wasted water generated by discharging the cold water at the time of using hot water, thus saving water.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It is obvious to those who have.

The present invention is applied to a technique for saving water by discharging hot water corresponding to a user-set temperature at all times through a preheating operation when supplying hot water using a boiler.
