Description

Water purifier and method of control the same

The present invention relates to a water purifier and a control method therefor, and more particularly, to a water purifier and a control method therefor, in which a user can easily recognize a location to place a container for accommodating discharged water without external lighting.

A water purifier is a device that purifies water for users to drink. Recently, as interest in health increases, the number of cases of drinking purified water with a water purifier is also increasing in general households.

A water purifier generally includes a filter for purifying raw water and a water outlet for discharging purified water. In a water purifier having a traditional structure, it is common that a lever disposed near the water outlet is operated to allow water to be discharged.

That is, when the user presses the lever using a container such as a cup, the member closing the water outlet is moved accordingly, and water is discharged through the water outlet.

However, the water purifier having the above structure should maintain a state in which the user presses the lever while water is drawn out. Accordingly, recently, in order to improve user convenience, a water purifier having a structure capable of extracting water by operating a button without operating a lever is also being actively developed.

In the case of a water purifier in which water is dispensed by manipulating a button, a means for informing the user that information through the button is input is required. This is due to the difficulty in intuitively recognizing whether or not information is input in the case of operation through a button compared to operation of a lever.

Accordingly, a general water purifier adopts a method in which the button is lighted when the button is operated, and outputs whether information is input to the user.

However, depending on the usage aspect, the water purifier may be located in an environment having low illumination. That is, the water purifier may be provided at a location where it is difficult to identify the location of the water purifier.

As an example, there is a case in which one wants to drink water by waking up at dawn during sleep. In the above case, since it is difficult to turn on the indoor light due to the presence of a person living with the room, it is not easy to identify the water purifier in a dark environment. Housework, even if you manage to find a water purifier and operate the button, the light emitted from the button does not indicate where the water will be discharged.

That is, the conventional water purifier is inconvenient in that additional lighting is required to arrange a cup for accommodating water to be discharged.

Korean Patent Laid-Open Publication No. 10-2008-0094423 discloses a water intake lighting device for a water purifier. Specifically, when the detection sensor detects an arbitrary object in front of the water purifier, an illumination LED coupled to the water intake port emits light. Disclosed is a water intake lighting device for a water purifier.

However, since this type of water intake lighting device for a water purifier is operated by a detection sensor, there is a fear that the lighting LED is unnecessarily emitted. That is, even when the user moves to the front side of the water purifier for entering the bathroom or other housekeeping activities, the lighting LED may be emitted unnecessarily.

Further, the illumination LED is formed to irradiate light into the switching valve. That is, the prior literature does not suggest a method for guiding the user with information about the location where the cup is to be placed.

Korean Patent Laid-Open Publication No. 10-2005-0074212 discloses a lighting device for a cold/hot water purifier and a method therefor. Specifically, a lighting device for a hot/cold water purifier including lighting units that emit light in different colors when a user selects water to be taken in is disclosed.

However, the lighting device of this type of cold/hot water purifier has a limitation in that the lighting device is operated only after the user selects water to be taken. That is, the lighting device may be operated only when the user operates a preset switch or encoder.

Therefore, there is a limit in that the user can recognize the location where the water is to be discharged only after inputting information for selecting the water to be taken out.

Korean Patent Publication No. 10-2008-0094423 (October 23, 2008) Korean Patent Publication No. 10-2005-0074212 (2005.07.18.)

In addition, when a user presses any one of an operation button and a water dispense button provided on the operation unit, light is emitted from the light emitting unit. Furthermore, even when the user inputs arbitrary voice information, light is emitted from the light emitting unit.

That is, when a user presses an arbitrary button or inputs arbitrary voice information, light is emitted from the light emitting unit.

Accordingly, the user does not need to press a specific button or input specific voice information in order to control the light to be emitted from the light emitting unit. Accordingly, user convenience may be improved.

In addition, when additional control information is not input during preset light emission time information after the light emitting unit starts to emit light, the light emitting unit is controlled to be extinguished.

Accordingly, even if the light emitting unit emits light due to a user's erroneous operation, the light emitting unit is extinguished when the user does not input additional control information for proceeding with water extraction. Accordingly, since the light emitting unit emits light only when water extraction proceeds, power consumption for operating the light emitting unit may be minimized.

After the light emitting unit 400 emits light, when the user does not additionally input control information while a predetermined time elapses, the light emission control module 570 controls the light emitting unit 400 to extinguish the light emitting unit 400 . It is a control step (S500).

That is, the light emitting unit 400 starts to emit light according to the first pressing information or voice information input by the user. In this case, if the user does not input additional pressing information or voice information even after a predetermined time has elapsed, it may be interpreted that the user does not intend to drain water.

Accordingly, in this step, when the user does not input additional control information for a predetermined time after the light emitting unit 400 starts to emit light, the light emission control module 570 controls the light emitting unit 400 to extinguish. .

The light emission control module 570 compares the calculated time information with preset light emission time information ( S520 ). That is, the light emission control module 570 calculates whether the elapsed time after the light emitting unit 400 starts light emission exceeds preset light emission time information.

When the calculated time information exceeds the preset light emission information, and control information is not additionally input during the calculated time information, the light emission control module 570 displays light emission information for controlling the light emitting unit 400 to be extinguished. Calculate (S530).

That is, when the user does not input additional control information while the light emitting unit 400 emits light for preset light emission time information according to the initially input control information, the light emission control module 570 extinguishes the light emitting unit 400 . Calculates information on whether or not to emit light.

The light emission control module 570 transmits the calculated light emission information to the light emission unit 400 (S540). The light emitting unit 400 is extinguished according to the transmitted light emission information.

Accordingly, when the user does not input additional control information after the user inputs the initial control information, the light emitting unit 400 may be extinguished. Accordingly, power for the operation of the light emitting unit 400 may be reduced.

Even in this case, since the light emitting unit 400 continues to emit light for at least the preset light emission time information, the user can easily recognize the position where the cup is to be placed.
