Description

A STERILIZED WATER CREATION DEVICE AND BIDDER HAVING THE SAME,

The present invention relates to a bidet comprising a sterilizing hand and a sterilizing hand.

Recently, as people's income has improved, living standards have become higher, and there is an increasing need to use clean water or high-quality water for drinking water as well as general living water such as washing water.

As a result, there has been published a device that has various water purification and sterilization functions due to the increased interest in water purification and sterilization of water. Generally, water purification is performed by using various filters and the like. A sterilizing agent, or sterilizing devices using ozone, ultraviolet rays, ultrasonic waves, or the like.

However, in the conventional sterilizing apparatus, if a chemical sterilizing agent is used, a sterilizing agent is further added to sterilize the sample. Therefore, a filtration process must be additionally performed. When the sterilizing apparatus is used, a separate sterilizing apparatus There is a problem that the device is complicated and the installation cost is increased because the device must be installed.

Accordingly, there has been proposed a sterilizing water producing apparatus using chlorine ions contained in water as sterilized water through electrolysis.

However, in the case of the electrolysis method, the magnitude of the current applied may vary depending on the amount of TDS (Total Dissolved Solids) contained in the water, that is, the total amount of dissolved solids, and the higher the concentration of TDS contained in the water, A current can flow. Therefore, when the concentration of the TDS is high, an overcurrent may be applied to the inside of the sterilizing water producing device, thereby causing a problem such that transistors and other components in the sterilizing water producing device are damaged.

Conventional low water sterilization water producing apparatus for sterilizing water by storing water reduces the electrolysis current by controlling the duty ratio of the input power according to the magnitude of the electrolysis current.

Such a sterilizing water producing apparatus for regulating the magnitude of the electrolysis current by the conventional duty ratio control requires a sufficient time for controlling the duty ratio to generate sterilized water by controlling the duty ratio.

However, in a direct-sterilization sterilizing water producing apparatus for producing sterilized water by using flowing water, sufficient time can not be ensured as described above. When water having a high TDS is supplied, the current suddenly rises, Suddenly consumes a large amount of current, so that power supply to another device sharing the power source becomes momentarily insufficient, and the device may be reset.

The following Patent Document 1 relates to a sterilizing machine, but fails to provide a solution to the above-mentioned problem.

However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. Further, the embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art.

In the drawings referred to in the present invention, elements having substantially the same configuration and function will be denoted by the same reference numerals, and the shapes and sizes of the elements and the like in the drawings may be exaggerated for clarity.

FIG. 1 is a view for explaining a sterilizing machine according to an embodiment of the present invention, FIG. 2 is a view for explaining an embodiment of a control part and an electrode shown in FIG. 1, and FIG. 3 is a cross- A first sensing unit, a second sensing unit, and a third sensing unit according to an embodiment of the present invention.

1, a sterilizing machine 10 according to an embodiment of the present invention includes an electrode 100, a converter unit 200, a first sensing unit 300, a control unit 400, a second sensing unit 500 A third sensing unit 600, and a feedback voltage regulator 700.

The electrode 100 can be discharged by the voltage V ₁ applied by the converter unit 200 to electrolyze the supplied water. 2, the electrode 100 may include a plurality of electrodes and a connector 130, and the plurality of electrodes may be distinguished as a positive electrode 110 and a negative electrode 120.

Here, the positive electrode 110 may be made of an alloy of IrO ₂ and Ta, and the negative electrode 120 may be made of stainless steel SUS (Steel Use Stainless). In addition, the distance between the positive electrode 110 and the negative electrode 120 may be 3 to 7 mm.

When the first voltage V ₁ is applied to the electrode 100, the water existing around the electrode 100 is electrolyzed to remove chlorine ions (Cl ^- ), ozone (O ₃ ), hydrogen peroxide (H ₂ O ₂ ) A sterilized water containing an oxidizing agent such as hydrochloric acid (HClO), hydroxyl group (OH < ^- & gt ^; ) or the like can be produced. Therefore, it is possible to disinfect the object using the generated sterilization water, oxidation reaction, reduction reaction, and neutralization reaction, or to remove organic substances such as bacteria that may be present in the object.

The converter unit 200 may generate the first voltage V ₁ by reducing the input voltage V _cc and may apply the first voltage V ₁ to the electrode 100. Here, the input power source V _cc may be supplied to or disconnected from the converter unit 200 according to a control signal of the control unit 400.

When the converter unit 200 applies the voltage to the electrode 100, the ions in the water move to the electrode 100 by the electrical attraction. At this time, the negative ions may provide electrons to the positive electrode 110, and the positive ions may receive electrons from the negative electrode 120. As a result, electrons entering the positive electrode 110 can be regarded as having passed through the negative electrode 120, so that current flows into the electrode 100. This is called electrolysis current.

Therefore, the electrolysis current I _EW can be determined according to the amount of ions present in the water, that is, the amount of total dissolved solids (TDS), and the higher the TDS concentration, the more electrolysis current Lt; / RTI >

The converter unit 200 can sense the magnitude of the electrolysis current I _EW flowing into the electrode 100 when the first voltage V ₁ is applied to the electrode 100, compared to the reference current value the size pre-set in the I _EW), the case where the electrolytic current (I _EW) is greater than or equal to the reference current value, the first voltage in proportion to the size of the electrolytic current (I _EW) (V ₁ Can be reduced.

Here, the converter 200 can reduce the magnitude of the first voltage V ₁ until it becomes zero, and can keep the output current constant regardless of the magnitude of the first voltage V ₁ .

In addition, the converter unit 200 may _{reduce the} input power supply voltage V _cc to the first voltage V ₁ . The converter unit 200 compares the first feedback voltage V _f1 provided from the first sensing unit 300 with a voltage value corresponding to the reference current value and outputs the first feedback voltage V _f1 If the voltage value is equal to or greater than the voltage value, the magnitude of the first voltage V ₁ may be reduced according to the magnitude of the electrolysis current I _EW .

The first sensing unit 300 may sense the magnitude of the electrolysis current I _EW between the converter unit 200 and the electrode 100. 3, the first sensing unit 210 may sense the first feedback voltage V _f1 applied by the electrolysis current I _EW flowing to the electrode 100 to the converter unit 200 To the first feedback path.

Specifically, the electrolysis current I _EW flows through the resistors R 2, R 3 and R 4, where the voltage applied to R4 by the electrolysis current I _EW is the first feedback voltage V _f1 And the first feedback voltage V _f1 may be fed back to the converter unit 200.

Controller 400 includes an input power supplied to the first voltage (V _1), the first voltage (V _1), the converter unit 200 and the size is not more than the preset reference voltage value, a control signal modulation of sensing the size of the (V _cc ).

In one embodiment, the control unit 400 may include a switching unit 410 and a microcomputer 420, as shown in FIG.

The switching unit 410 is disposed on a path where the input power source V _{cc is} provided to the converter unit 200 and on / off can be adjusted according to a control signal of the microcomputer 420. In one embodiment, the switching unit 410 may include a resistor R1, a capacitor C1 and a transistor Q, and the control signal may be input to the base terminal of the transistor Q. When the control signal is input, the transistor Q is turned on so that the input power source V _cc may be provided to the converter unit 200.

The microcomputer 420 compares the second feedback voltage V _f2 provided from the second sensing unit 500 with a reference voltage value and if the second feedback voltage V _f2 is less than the reference voltage value, The input power V _cc provided to the converter unit 200 can be cut off by turning off the transistor Q of the switching unit 410 by adjusting the signal.

The second sensing unit 500 may sense the magnitude of the first voltage V ₁ applied to the electrode 100 by the converter unit 200. 3, the second sensing unit 500 may sense the second feedback voltage V _f2 applied by the first voltage V ₁ applied to the electrode 100 to the microcomputer 420 To the second feedback path.

Specifically, the first voltage (V ₁₎ is R5, and partitioned between R6 and R7, where, and the voltage applied to R7 may be the second feedback voltage (V _f2), the second feedback voltage (V _f2) is And can be fed back to the microcomputer 420.

The larger the TDS value of water, the larger the electrolysis current. However, if the value of the electrolysis current becomes too large, the internal components may be burned down and may affect other devices inside the appliance (e.g., a bidet or a water purifier) including the sterilizing handler 10 .

In order to solve such a problem, it is necessary to supply the input power to the converter unit 200 to operate the sterilizing handler 10 only when the TDS value of the water is within an appropriate range. For this, an upper limit (for example, 500 ppm) of a proper TDS value that does not cause the above problems is set, and a value of the first voltage V ₁ reduced by the converter unit 200 according to the TDS value Can be set as a reference voltage value.

The third sensing unit 600 may sense the output current I _o output from the electrode 100. In one embodiment, the third sensor 600, it is possible, as shown in Figure 3, comprise a detection resistor (R ₈₎ disposed between the electrode 100 and the ground.

The feedback voltage regulator 700 may adjust the magnitude of the first feedback voltage V _f1 according to the magnitude of the output current I _o detected by the third sensing unit 600.

Specifically, the feedback voltage controller 700 compares the magnitude of the output current I _o detected by the third sensing unit 600 with the reference current value, and determines whether the magnitude of the output current I _o is greater than the reference current value It is possible to output the correction voltage according to the magnitude of the output current I _o to the first sensing unit 300. In one embodiment, the magnitude of the correction voltage may be proportional to the magnitude of the output current I _o . Here, the output current I _o may be equal to the electrolysis current I _EW .

This feedback voltage regulator 700 will be described in more detail below with reference to FIG.

4 is a view for explaining an embodiment of the feedback voltage regulator shown in FIG.

Referring to FIG. 4, the feedback voltage controller 700 according to an embodiment of the present invention may include a first amplifier 710 and a second amplifier 720.

The first amplifier 710 receives and amplifies both ends of the detection resistor R ₈ . Here, the first amplifier 710 can amplify the voltage across the detection resistor R ₈ with a gain determined according to the magnitudes of the resistor R _a1 and the capacitor C _a1 .

The second amplifying unit 720 compares the output of the first amplifying unit 710 with the voltage value corresponding to the reference current value so that the magnitude of the output voltage of the first amplifying unit 710 corresponds to the reference current value It is possible to output the correction voltage according to the magnitude of the output current I _o to the first sensing unit 300. [ Here, the second amplifier 720 may output the correction voltage with a gain determined according to the magnitude of the resistor R _a2 and the capacitor C _a2 .

Here, the sum of the voltage applied to R4 by the electrolysis current I _EW and the correction voltage output by the second amplifying unit 720 may be the first feedback voltage V _f1 , The voltage V _f1 may be fed back to the converter unit 200.

5 is a graph for explaining the relationship between the first voltage and the electrolysis current of the sterilizing water purifier according to the embodiment of the present invention.

5, when the first voltage V ₁ is applied to the electrode 100 by the converter unit 200, the electrolysis current I _EW flows through the electrode 100 and is supplied to the electrode The higher the TDS value of water, the larger the electrolysis current (I _EW ) value can be. The converter unit 200 receives the electrolysis current I _EW through the first sensing unit 300 and outputs the first voltage V ₁ if the electrolysis current I _EW is greater than the reference current I _ref . Can be reduced.

If the correction voltage output from the feedback voltage regulator 700 is not reflected in the first feedback voltage V _fb1 fed back to the converter 200 through the first sensing unit 300, I _EW ) is greater than the reference current I _ref , the magnitude of the first voltage V ₁ may not decrease.

That is, the feedback voltage controller 700 compares the magnitude of the output current I _o detected by the third sensing unit 600 with the reference current value. If the magnitude of the output current I _o is equal to or greater than the reference current value And outputs the correction voltage according to the magnitude of the output current I _o to the first sensing unit 300 so that the value of the electrolysis current I _EW or the output current I _o is greater than the reference current I _ref The magnitude of the first voltage V ₁ can be linearly reduced according to the magnitude of the electrolysis current I _EW or the output current I _o .

Here, when the first voltage V ₁ , which is reduced according to the magnitude of the electrolysis current I _EW , is equal to or lower than the reference voltage V _cutoff , the controller 400 controls the input power V _cc ).

Here, the feedback voltage regulator 700 may adjust the gain of the second amplifier 720 to adjust the slope of the first voltage V ₁ , which is decreased according to the magnitude of the output current I _o .

That is, as the gain of the second amplifier 720 determined according to the magnitude of the resistor R _a2 and the capacitor C _a2 of the second amplifier 720 increases, the absolute value of the slope can be increased , So that the input power source V _cc provided to the converter unit 200 can be cut off even if the electrolysis current I _EW flows smaller than (1) when the slope value is small.
