Description

Device for dechlorinating from water in washing machine

The present invention relates to a washing water dechlorination apparatus for a washing machine, and more particularly, a washing water dechlorination apparatus for preventing discoloration of colored clothes by removing chlorine components contained in washing water or rinsing water supplied into a washing tank. It is about.

In general, a washing machine is a household appliance that removes various contaminants attached to clothes, bedding, etc. by using the emulsification of the detergent and the friction action of the water flow due to the rotation of the pulsator and the impact action of the pulsator on the laundry. to be.

In the conventional washing machine, as shown in FIG. 1, an outer case 16, an outer tub 17 installed inside the outer casing 16 and filled with washing water therein, and installed inside the outer tub 17 are washed and Washing tank (1) for performing dehydration, a pulsator (18) installed in the lower portion of the washing tank (1) to form a water flow by stirring left and right, and a pulsator for generating a driving force to rotate the pulsator (18) A drive motor 19 is provided.

In addition, the water supply port 20 for supplying the wash water into the outer tub 17, and a detergent inlet tank 14 for containing a detergent to be put into the washing tank 1 with the wash water at the time of water supply for washing; Is connected to the lower side of the outer tank 17 is provided with a drain hose 22 for discharging the laundry wastewater to the outside in accordance with the action of the drain valve 21.

Therefore, in the conventional washing machine, when the user selects the washing course and turns on the operation button, the washing machine detects the amount and type of the laundry by the sensor and automatically sets the washing method. After watering up to an appropriate water level according to the type, washing is performed under the control of a microcomputer (not shown).

On the other hand, tap water, which is supplied into the washing tank 1 and used as washing water or rinsing water, is chlorinated for disinfection in raw water, and some of the chlorine is volatilized into the atmosphere during the water purification process and the process of being supplied to each household. They are naturally removed, but not all of them, and the rest remains in the water.

Therefore, when the tap water is used as the wash water, there is a problem that the decolorization of the colored clothing is caused by the chlorine component contained in the tap water used as the wash water.

In other words, the free chlorine contained in the tap water decomposes the chromophore molecules, which give off the color of colored clothing, resulting in the discoloration of the clothing, which may result in undesirable effects for the user.

On the other hand, in order to prevent the discoloration of clothing caused by the chlorine component of the tap water by receiving the tap water in a water tank of a certain capacity and leaving the lid open for several days, the chlorine component contained in the tap water is volatilized to the atmosphere, or The detergent is first dissolved in the wash water, and the laundry is added to the wash water in which the detergent is dissolved.

However, the method of using tap water after leaving the tap water is inefficient and cumbersome in terms of time and space utilization, and the method of injecting laundry after removing the detergent is also difficult and practical to apply.

Therefore, when washing using a washing machine, in order to prevent discoloration of colored clothing, dechlorination means for removing residual chlorine contained in the washing water supplied to the washing tank 1 is required. 1) There was no means to remove residual chlorine contained in the wash water supplied into the wash water.

For reference, the principle of the color of the chlorine to discolor the colored clothing described in more detail as follows.

The color of an object is a phenomenon in which the object receives an energy from a light source and causes the electron potential of the object to become a complementary color of absorption. A structure having a double bond or an unshared electron pair in the chemical structure inside the object is visible in the visible range. It is excited by energy and colored, but the single bond structure cannot be colored because electron potential does not occur with energy in the visible light region.

In other words, the chemical structure of a colored object has double bonds or non-covalent electron pairs, and these chemical structures are called chromophores or chromophores.

On the other hand, colored clothing having such a chromophore has a double bond (π bond) structure, and the free chlorine in the wash water reacts with the chromophore in the dye of the colored clothes to form a single bond (ρ bond) structure, thereby forming a chromophore. By changing the properties will not be color.

The present invention is to solve the above problems, by preventing the chlorine component contained in the washing water or rinsing water supplied into the washing tank is volatilized and removed on the water supply path into the washing tank to prevent the discoloration of colored clothes during washing or rinsing It is an object of the present invention to provide a washing water dechlorination apparatus of a washing machine.

In order to achieve the above object, the present invention is a residual chlorine volatilization having a spreader for supplying air to the wash water to remove the chlorine component contained in the wash water on the wash water supply line for supplying the wash water to the washing tank Washing water dechlorination apparatus of a washing machine provided with a means.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

Figure 3 is a block diagram showing the configuration of the water supply line of the washing machine according to the present invention, Figure 4 is a longitudinal sectional view showing an embodiment of the washing water dechlorination apparatus of the present invention, washing to supply the washing water to the washing tank (1) Residual chlorine volatilization means for blowing and removing the chlorine component contained in the wash water by blowing air to the wash water on the water supply line (2) is provided.

Meanwhile, the residual chlorine volatilization means includes a dechlorination tank (5) having a washing water inlet (3) and a washing water outlet (4), a spreader (6) installed in the dechlorination tank (5), and the spreader ( 6) an air injection line 7 connected to the air injection line 7 and an air pump 8 connected to the air injection line 7 to supply air to the spreader 6, and an upper portion of the dechlorination tank 5 It consists of a fan (9) for discharging the chlorine component volatilized in the dechlorination tank (5) to the outside, and a fan drive motor (10) for driving the fan (9).

At this time, the washing water outlet 4 of the dechlorination tank 5 is formed at a position higher than the washing water inlet 3, it is formed to have a larger flow path cross-sectional area than the washing water inlet (3).

In addition, a residual water outlet 11 for discharging residual water in the dechlorination tank 5 so that the washing water does not remain in the dechlorination tank 5 after water supply is completed in the lower portion of the washing water outlet 4 of the dechlorination tank 5. Is formed.

On the other hand, under the fan (9) of the dechlorination tank (5) selectively discharges only the chlorine component volatilized so as to prevent the water introduced into the dechlorination tank to splash up and sucked into the fan (9) while hitting the spreader (6) Hydrophobic filter is installed.

At this time, the filter 12 does not pass through the filter 12, so that the washing water formed on the surface of the filter 12 can be more effectively aggregated to fall back into the dechlorination tank (5) portion of the filter 12 is the remaining portion Is formed low for.

That is, the filter 12 may have a V-shaped structure having a central portion lower than that of the outside, or a structure inclined in one direction.

The operation of the present invention configured as described above is as follows.

In the process of supplying water for washing or rinsing, a part of the washing water introduced into the washing water supply line 2 through the water supply valve 13 flows into the detergent input tank 14 for the detergent input, and most of the remaining washing water. Is introduced into the dechlorination tank (5).

That is, the washing water flowing along the branch line of the dechlorination tank 5 in the branch line of the washing water supply line 2 passes through the washing water inlet 3 of the dechlorination tank 5 and flows into the dechlorination tank 5. do.

Accordingly, the washing water is filled from the bottom of the dechlorination tank 5 to the top to the washing water outlet 4 position.

In addition, the compressed air generated when the air pump 8 is turned on is introduced into the spreader 6 through the air injection line 7, and then comes out to the spreader 6 to be fine and a large number. Air bubbles will form.

As a result, volatilization of the chlorine component contained in the wash water occurs in the wash water. As the amount of air supplied and the amount of bubbles generated increase, the volatilization action is accelerated.

That is, the finer and the more air bubbles released through the spreader 6, the larger the surface area of the wash water in contact with the air. Accordingly, the volatilization of the chlorine component also proceeds more actively.

On the other hand, the chlorine component volatilized by the action of the spreader 6 is forcibly discharged to the outside by the suction force of the fan 9 in the form of chlorine gas.

At this time, the filter 12 installed under the fan 9 serves to block water drops and discharge only chlorine gas.

In addition, since the hydrophobic filter 12 having a V-shaped structure of the filter 12 is provided, the cohesion force between the water drops formed on the filter 12 is improved, and the water droplets formed on the filter 12 drop rapidly.

On the other hand, the dechlorinated wash water flows into the detergent input tank 14 through the laundry water outlet, and then flows into the washing water inlet 15 of the upper portion of the detergent input tank 14, which is contained in the detergent input tank 14. The laundry is dissolved in the detergent and enters the washing tank 1.

Further, a residual water outlet is formed in the lower portion of the washing water outlet 4 of the dechlorination tank 5 so that all the washing water in the dechlorination tank 5 is discharged while the supply of the washing water is stopped.

This is for the purpose of preventing the freezing of the dechlorination tank (5) by the decay of the residual water generated when the washing water remaining in the dechlorination tank (5) and the winter residual water.

Meanwhile, the washing water outlet 4 of the dechlorination tank 5 is formed to have a larger flow path cross-sectional area than the washing water inlet 3, which is sprayed or sprayed into the dechlorination tank 5 by the ejector 6. In order to allow the chlorine component of tap water to evaporate in the process, when the amount of tap water discharged through the outlet is smaller than the amount of tap water injected, internal pressure is formed in the dechlorination tank 5 so that tap water is filled in the dechlorination tank. This is because evaporation performance may be reduced.

As described above, the present invention allows the chlorine component remaining in the wash water flowing into the washing tank (1) to be quickly removed on the water supply path to prevent the discoloration of colored clothing due to the wash water to use the washing machine due to the discoloration of the clothing Discomfort can be eliminated.

In addition, since the dechlorination apparatus of the present invention is a mechanical apparatus that volatilizes and removes chlorine components in washing water, the dechlorination apparatus has high reliability in terms of maintenance, maintenance, and lifespan of the apparatus.
