For example, when the lever 130 is pushed or pulled in the original position of the lever 130, the upper end of the lever 130 presses the micro-switch depressing portion to switch the switch of the micro-switch 136 from switch-off to switch- . When the lever 130 is released, the elasticity restoring force of the spring mounted on the upper end of the lever 130 is restored to its original position, and the switch signal is turned off again.

The outgoing signal outputted from the micro switch 136 is transmitted to a controller 150 such as a controller built in the cabinet 110 and the controller 150 applies power to the hot water or cold water / constant solenoid valve 135 The solenoid valve 135 is operated. The hot water, the cold water, or the purified water is discharged according to the operation of the solenoid valve 135.

The cork housing 120 is equipped with an illuminating unit 129 such as a printed circuit board (hereinafter referred to as PCB 128). A certain volume of storage space is provided inside the cock housing 120 so that the PCB 128 can be inserted.

The front surface of the cork housing 120 is provided with a selection button 123 that can be easily operated by a user. The selection button 123 may include a first selection button 123a provided in the first cock housing 121 and a second selection button 123b provided in the second cock housing 122. [ The select button 123 is provided at the lower part of the cock housing 120 and is positioned adjacent to the outflow cock 124.

The illumination unit 129 may include a PCB 128, a selection button 123 mounted on the PCB 128, a power supply unit, a light-emitting diode LAMP 127, a light switch, and the like.

Here, the PCB 128 may be provided separately from the MAIN PCB 128 to perform cold water and hot water outlet functions.

The power supply unit supplies stable power to meet the conditions for driving the illumination lamp such as the LED lamp 127. [ For example, it may be a switching mode power supply (SMPS) by a switching operation. SMPS can be reduced in size and weight due to the switching frequency of several tens to several hundreds of kHz due to the switching frequency of several tens to several hundred kHz and minimizes unnecessary loss due to switching operation ('on', 'off'). There are advantages.

The LED lamp 127 is selectively turned on / off by a selection button 123 as an illumination lamp, and generates light to display the function selected by the user.

In the case of the LED lamp 127, the first and second LED lamps 127a and 127b are mounted on the first cork housing 121 and the third and fourth LED lamps 127c and 127b are mounted on the second cork housing 122, 127d may be mounted on each of them. The plurality of LED lamps 127 may be selectively operated according to various modes set to perform a selectable function in the case of hot water and cold water.

The LED lamps 127 may be configured in various colors according to functions or purposes to be performed. The LED lamp 127 for hot water outflow is realized by a red light emitting LED and the LED lamp 127 for cold water or water outflow is realized by an LED emitting green or blue light.

The illumination switch may be connected between the power supply and the LED lamp 127 to apply power to the LED lamp 127 to turn on / off the power to be applied to the LED lamp 127. The illumination switch is disposed so as to be in contact with the selection button 123 and can selectively apply power to the LED lamp 127 in conjunction with the selection button 123.

An indicator 126 is provided on the front surface of the cork housing 120 to indicate the function selected by the select button 123. The indicator 126 includes a first indicator 126a and a second indicator 126b mounted on the first cock housing 121 and a third indicator 126c and a fourth indicator 126c provided on the second cock housing 122. [ (126d).

The indicator 126 is a transparent or transparent material. Accordingly, the user can recognize the selected function by viewing the light transmitted through the indicator 126 and the characters written around the indicator 126 by transmitting the light generated from the LED lamp 127 to the outside.

The indicator 126 may have various shapes according to modes of operation related to the outflow of hot water and cold water. For example, it may be in the form of indicating the lock of the lock when displaying the hot water lock function. In addition, when the hot water releasing function is displayed, the lock may be configured to indicate that the lock is released. In addition, it may be in the form of a water drop display in the case of displaying an integer selection function, and in a display form such as snow or ice in the case of displaying a cold water selection function.

In addition, the characters written around the indicator 126 may be labeled 'lock' in the hot lock mode, 'unlock' in the hot water release mode, 'cold water' and 'hot water' in the cold water mode and hot water mode have.

The shape of the indicator 126, characters written in the indicator 126, and the like are not limited to these, and may be expressed in various forms and characters.

And the separating plate 125 is provided on the inner surface of the cock housing 120. The separation plate 125 is provided at a boundary portion between the adjacent indicators 126 so that light generated between the indicator lamps 126 when the light generated from the LED lamp 127 is transmitted through the indicator 126, Thereby preventing light from diffusing into the indicator 126.

For example, in the case of the cock housing 120, the separator plate 125 is protruded toward the PCB 128 from the inner surface of the cock housing 120. More specifically, the end of the separation plate 125 is protruded to face the vertical center line of the PCB 128. Since the separator plate 125 is used for blocking interference and diffusion of light, it is preferable that the separator plate 125 is not a transparent or transparent material but an opaque material or a material coated with a reflective material.

Accordingly, the light generated in the first LED lamp 127a is transmitted through the first indicator 126a, and the light diffused toward the second indicator 126b is blocked. The light generated by the second LED lamp 127b is also transmitted through the second indicator 126b by the separation plate 125 and cut off the light diffused into the first indicator 126a. Even in the case of the third LED lamp 127c and the fourth LED lamp 127d, interference of light can be prevented by the separation plate 125. [

In addition to the function of blocking the interference of light, the separator 125 may also support the PCB 128.

The separating plate 125 and the mounting surface of the PCB 128 are vertically arranged in the direction intersecting with each other and the separating plate 125 protruding from the inner surface of the cork housing 120 toward the mounting surface of the PCB 128, Extends with a constant gap (GAP) with the mounting surface of the PCB (128). This is for inserting and mounting the PCB 128 into the gap formed between the end of the separation plate 125 and the mounting surface of the PCB 128.

The insertion space of the PCB 128 is limited by the gap and when the PCB 128 is inserted between the end of the separation plate 125 and the mounting surface of the PCB 128, the PCB 128 can be supported in a back- have.

The cork housing 120 is provided on both sides of the coupling member 120a so that the cork housing 120 can be coupled to the water outlet 111 of the cabinet 110 by screws or the like. The engaging member 120a is provided with a through hole for screwing.

The selection button 123 is pressed by the user. If the selection button 123 is pressed, a predetermined function can be performed.

6 is a block diagram showing functions and control flow selectable by the select button 123 according to the present invention.

Here, the functions selectable by the selection button 123 are as follows.

First, it automatically switches from hot lock mode to hot water release mode.

In general, since the hot water is at a high temperature of about 90 ° C, the user may push the hot water out of the user's skin. A hot water lock mode in which hot water can not be discharged is set. The hot water releasing mode means that the hot water can be discharged when the lever 130 is pushed or pulled.

When the user presses the first selection button 123a, the user is automatically switched to the hot water releasing mode, and hot water can be taken out through the first water cork 124a.

Second, it is a function that automatically returns to the hot water lock mode after a predetermined time elapses in the hot water release mode.

The user returns to the hot water lock mode after a lapse of a predetermined time, for example, 1 second to 3 seconds, in a state where the pressing force is released from the first selection button 123a. This is an essential function for the safety of the user. Therefore, it is desirable to prevent the user from changing the function set at will.

Third, it selects the cold water or constant mode. The cold water mode is a state in which cold water can be dispatched, and the integer mode is a state in which an integer can be dispatched.

At the beginning of the product release, the default (default) or cold water mode can be set by the designer. Of course, it may be set to integer mode.

For example, when the mode is initially set to the cold water mode, the user can operate the lever 130 without operating the second selection button 123b, thereby leaving the cold water immediately. If the second selection button 123b is pressed, the water is automatically switched from the cold water mode to the constant water mode, and the lever 130 can be operated to exit the constant water.

If the integer mode is initially set, the operator can operate the lever 130 without manipulating the second selection button 123b to exit the routine. In this case, when the second selection button 123b is pressed, the water is automatically switched from the integer mode to the cold water mode, and the lever 130 can be operated to dispense cold water.

Fourth, automatic return to cold water or constant mode.

When the user presses the second selection button 123b and the outgoing is completed, the user returns to the original mode when a predetermined time elapses. For example, when the initially set mode is the cold water mode, the water is automatically returned from the constant mode to the cold water mode when the set time elapses after the second selection button 123b is pressed. Thereby, the user can take out the cold water without operating the separate selection button 123. Also, when the initially set mode is the integer mode, the second selection button 123b is pressed, and then the integral mode is automatically returned when the set time has elapsed.

Fifth, it is a function to fix the cold water mode or constant mode.

These functions can be set when the user wants to use the fixed mode in the cold water mode or the constant mode.

For example, when the user selects the second selection button 123b in the cold water mode without pressing the second selection button 123b, the user presses the second selection button 123b for longer than a predetermined time And can be fixed in integer mode.

Next, in the integer mode, if the user presses the second selection button 123b longer than a preset time, the integer mode is released and can be fixed in the cold water mode.

That is, if the second selection button 123b is held down for a long time, the previously selected mode is released and fixed to the other mode.

It is also possible to hold the second selection button 123b in a previously selected mode by pressing and holding the second selection button 123b. For example, if the second selection button 123b is pressed and held, the previously selected cold water mode can be fixed.

A control method of the water purifier 100 having the selection button 123 having the above-described selection function will be described as follows.

FIG. 7 is a flowchart showing a purifier control method according to the present invention.

It is assumed that the initially set mode in relation to the hot water outflow function is the hot water lock mode and that the initially set mode in relation to the cold water / water outflow function is the cold water mode.

The first indicator 126a initially set in relation to the display function of the indicator 126 indicates a hot water lock mode, the second indicator 126b indicates a hot water release mode, the third indicator 126c indicates an integer mode And the fourth indicator 126d indicates the cold water mode.

It is determined whether or not the user has pressed the first selection button 123a (S110) or the second selection button 123b (S120).

When the first selection button 123a is pressed, the light generated from the second LED lamp 127b is transmitted through the second indicator 126b, and the hot water release mode is activated in the hot water lock mode (S111). Thereby, the user can recognize that it is in the hot water release mode. On the other hand, in a state in which the first selection button 123a is not pressed, the light generated from the first LED lamp 127a is transmitted through the first indicator 126a, and the user can recognize that it is the hot water lock mode ).

In step S130, it is determined whether the user pushes or pulls the lever 130 in the hot water release mode. However, in the hot water lock mode, the hot water solenoid valve is not operated regardless of the operation of the lever 130 of the user, and the hot water passage is shut off (S132).

When the lever 130 is pushed or pulled, a control signal is transmitted to the hot water solenoid valve, and the hot water solenoid valve is opened in accordance with the control signal, and the hot water flows out through the hot water induction pipe (S131). Thereby, the user can drink the desired hot water.

It is determined whether a predetermined time has elapsed since the operation of the first selection button 123a (S150).

When the preset time has elapsed, the hot water release mode is automatically returned to the hot water lock mode (S151). If the predetermined time has not elapsed, the activated state of the hot water release mode is maintained (S111).

When the second selection button 123b is pressed, light generated from the third LED lamp 127c is transmitted through the third indicator 126c and activated in the constant mode in the cold water mode (S121). Thereby, the user can recognize that it is the integer mode. On the other hand, in a state in which the second selection button 123b is not pressed, the light generated from the fourth LED lamp 127d is transmitted through the fourth indicator 126d, and the user can recognize that the mode is the cold water mode (S122) .

In step S140, it is determined whether the user pushes or pulls the lever 130 in the integer mode or the cold water mode.

In the constant mode, when the lever 130 is pushed or pulled, the control signal is transmitted to the constant solenoid valve 135b, and the constant solenoid valve 135b is opened in accordance with the control signal, And exits through the second outgoing cock 124b (S141). Thereby, the user can use the desired integer for the purpose of drinking or the like.

When the lever 130 is pushed or pulled in the cold water mode, a control signal is transmitted to the cold water solenoid valve 135a, and the cold water solenoid valve 135a is opened according to the control signal, Via the second outflow cork 124b (S141). Thus, cold water desired by the user can be used for drinking or the like.

It is determined whether a predetermined time has elapsed since the operation of the second selection button 123b (S160).

If the predetermined time has elapsed, the water is automatically returned from the constant water mode to the cold water water mode (S122). If the predetermined time has not elapsed, the activated state of the integer mode is maintained (S142).

In the above description, the water purifier 100 is described as being composed of three flow passages, that is, hot water, cold water, and purified water. However, the water purifier 100 may be composed of two channels, that is, hot water and cold water or cold water and purified water. FIG. 8 is a front view showing a water purifier 200 to which two flow paths according to the present invention are applied.

In this case, the components such as the cabinet 110, the cork housing 220, the lever 230, the selection button 223, the illumination unit, and the plurality of indicators 226a and 226b are the same as those in the water purifier having three flow channels And therefore, a detailed description thereof will be omitted.

However, when the hot water passage and the cold water passage are provided in the two cabinets 220, for example, the cabinet 220, the lever 230, the plurality of indicators 226, Can be assembled into one assembly on top of the stand 111.

One lever 230 is rotatably hinged to the cock housing 220 and one select button 223 is provided and the indicator 226 includes two first indicators 226a for indicating a hot water mode and a cold water mode, And a second indicator 226b. The illumination unit may include two LED lamps on one PCB to transmit light through the first and second indicators 226a and 226b. A separation plate is provided between the first and second indicators 226a and 226b so that light to be irradiated by the first and second indicators 226a and 226b can be separated without interfering with each other.

For example, in a water purifier that can be selected as the hot water mode and the cold water mode, it can be initialized to the cold water mode when the selection button 223 is not pressed. In this case, the operation of pressing the selection button 223 to switch from the hot water lock mode to the hot water release mode can be omitted. This is because the initially set cold water mode can perform the same function as the hot water lock mode. That is, the operation of pressing the selection button 223 to switch the hot water lock mode to the hot water release mode and the operation of pressing the selection button 223 to switch the cold water mode to the hot water mode require the selection button 223 Because they are the same or similar in terms of preference.

The purifier described above is not limited to the configuration and the method of the embodiments described above, but the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications may be made.
