Abstract

PURPOSE: An automatic water supplying system and a control method thereof are provided to automatically supply hot water and cold water according to a sensing data of a sensor which senses the approach of a cup around a water cock. CONSTITUTION: A controller(102) drives an approach sensor(104) according to a key signal setting an automatic water supply mode. A solenoid valve(106) is driven by the logic signal from the approach sensor. The solenoid valve is closed to intercept the supply of cold and hot water after a first predetermined time passes by. Then, the controller decides if a second predetermined time passes by and if so, the controller drives the solenoid valve again after the approach sensor feeds a logic signal.

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

1 is a schematic functional block diagram of a system for automatically supplying a cold / hot water of a cold / hot water machine according to a preferred embodiment of the present invention, wherein a key input unit 100, a control unit 102, a proximity sensor 104, and a solenoid valve are provided. valve 106.

As shown, the key input unit 100 is a means for generating an electrical signal in response to the user's input behavior, in the present embodiment is used as a key signal generating means for the automatic / manual mode setting of cold / hot water. That is, by the input of the key input unit 100 may be set to the automatic mode that can automatically supply the cold / hot water, or, if necessary, can be set to the manual mode to supply only the cold / hot water manually. The key input unit 100 may be composed of two buttons, that is, an automatic mode setting button and a manual mode setting button, or may also be configured as a single button of a toggle type, which is the technical field of the present invention. Those skilled in the art will readily know.

Proximity sensor 104 according to the present invention is formed on the front of the cold / water heater to detect the approach of the external object, that is, the cup, and provides the detected data to the controller 102 to be described later. Such a proximity sensor is shown in more detail in FIG. 2.

As shown in FIG. 2, the proximity sensor 104 according to the present exemplary embodiment is formed at positions adjacent to the cold / hot water coke 202 of the cold / hot water heater 200, and thus can detect the approach of the current cup. have. The proximity sensor 104 may apply a sensing means capable of detecting a movement of an external object, for example, an infrared sensor, an optical sensor, an analog output sensor, or the like.

On the other hand, the solenoid valve 106 is configured at a predetermined position inside the cold / hot water heater, and opens / closes the flow of cold / hot water by being turned on / off by a control signal of the controller 102 described later. As the solenoid valve 106 is operated by an electrical signal, it will be easily understood by those skilled in the art, detailed description thereof will be omitted.

The control unit 102 according to the present invention drives the proximity sensor 104 according to the cold / hot water automatic supply mode setting key signal from the key input unit 100 described above, and according to the logic signal provided from the proximity sensor 104. The on / off drive of the solenoid valve 106 is controlled.

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figure 3 attached to the automatic supply of cold / hot water of the cold / hot water machine according to a preferred embodiment of the present invention will be described in detail.

First, in step S300 the control unit 102 determines whether the current cold / hot water is in the automatic mode. That is, it is determined whether a cold / hot water automatic supply mode capable of automatically supplying cold / hot water is set by a key signal input of the key input unit 100.

If it is determined in step S300 that the automatic mode, the control unit 102 proceeds to step S302 to turn on the proximity sensor 104 to detect the approach of the outer cup, and proceeds to step S304.

In step S304, the control unit 102 determines whether predetermined sensing data is provided from the proximity sensor 104. That is, it is determined whether a logic signal, for example, a high signal, generated as the cup approaches the proximity sensor 104 by the user's action is applied.

As a result of the determination of step S304, if a high signal is applied, the control unit 102 proceeds to step S306 to turn on the solenoid valve 104 to allow the flow of cold / hot water.

At this time, in the present invention, incidentally, the supply of cold / hot water may be limited for a certain time to prevent excessive supply of cold / hot water. That is, the controller 102 determines whether the current cold / hot water supply time exceeds a first set time, eg, 3 seconds, in step S308. The solenoid valve 106 is turned off to block the flow of cold / hot water.

In addition, the controller 102 proceeds to step S312 to determine whether the solenoid valve 104 is turned off and whether the second set time, for example, two seconds, has elapsed, and if the second set time has elapsed, the controller 102 The flow returns to step S304 to repeat the above-described processes.

On the other hand, if the determination result of step S314, if the cold / hot water manual supply mode setting key signal is input from the key input unit 100, the control unit 102 proceeds to step S316 to turn off the proximity sensor 104 to cool Only supply hot water manually and terminate this procedure.

As described above, the present invention is equipped with a sensor that detects the approach of an external object, that is, the cup around the cold / hot water cock of the cold / hot water heater, and implements to automatically supply the cold / hot water according to the sensing data of the sensor It was.

Therefore, the present invention is convenient to use the cold / hot water, there is an effect of ease of use for the consumer, maximizing the sales to the supplier.
