Description

Washing water dechlorination unit of washing machine

The present invention relates to a washing water dechlorination apparatus for a washing machine, and more particularly, to remove the chlorine component contained in the washing water or the rinsing water supplied into the washing tank by removing the chlorine component from the water supply path to prevent discoloration of the colored clothes. A washing water dechlorination apparatus.

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 13, an outer tub 14 installed inside the outer casing 13 and filled with washing water therein, and installed inside the outer tub 14 are washed and Washing tank (1) for performing dehydration, a pulsator (15) 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 (15) A drive motor 16 is provided.

In addition, a water supply port 17 for supplying the wash water into the outer tub 14, and a detergent inlet tank 12 for storing the detergent introduced into the washing tank 1 with the wash water at the time of water supply for washing; It is connected to the lower side of the outer tub 14 is provided with a drain hose 19 for discharging the laundry wastewater to the outside according to the action of the drain valve 18.

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, so most of them remain 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-mentioned problems, by preventing the chlorine component contained in the wash 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.

In order to achieve the above object, the present invention is a washing water dechlorination apparatus of the washing machine having a residual chlorine volatilization means for volatilizing and removing the chlorine component contained in the water on the washing water supply line for supplying the washing water to the washing tank to be.

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 volatilizing and removing the chlorine component contained in the wash water is provided on the water supply line (2).

Meanwhile, the residual chlorine volatilization means includes a dechlorination tank (5) having a washing water inlet (3) and a washing water outlet (4) connected to the washing water supply line (2), and washing water on one side of the dechlorination tank (5). Ejector (6) connected to the inlet (3) and the washing water is injected into the space inside the dechlorination tank (5) and the chlorine is installed on the dechlorination tank (5) volatilized in the dechlorination tank (5) A fan 7 for forcibly discharging the components to the outside, and a fan drive motor 8 for driving the fan (7).

At this time, the filter (9) to selectively discharge only the volatilized chlorine component while preventing the water sprayed from the ejector 6 is sucked into the fan 7 in the lower portion of the fan (7) of the dechlorination tank (5) Is installed.

In addition, the filter 9 may not pass through the filter 9 so that the washing water formed on the surface of the filter 9 may be more effectively aggregated so that the filter 9 may fall back into the dechlorination tank 5. Formed low.

That is, the center portion is possible with a V-shaped structure lower than the outside.

Further, the filter 9 may be installed to be inclined in one direction in the desalination tank.

Meanwhile, an air inlet 10 for increasing volatilization of residual chlorine by increasing an inflow amount of air introduced into the dechlorination tank 5 on one side of the ejector 6 increases the contact area between residual chlorine and air. ) Is formed.

In addition, the washing water outlet 4 of the dechlorination tank 5 is formed to have a cross-sectional area larger than that of the flow path of the washing tank inlet 3.

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

In the process of water supply for washing or rinsing, a part of the washing water introduced into the washing water supply line 2 through the water supply valve 11 flows into the detergent input tank 12 for 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 connected to the dechlorination tank 5 is injected into the dechlorination tank 5 together with the air sucked through the air inlet in the form of small particles through the ejector 6.

In this process, almost all free residual chlorine (water disinfection component) contained in the washing water is volatilized, which is sprayed through the ejector 6 and the washing water is granulated to increase the contact area between the washing water and the air. This is because the volatilization of the chlorine component contained in is accelerated.

Then, the chlorine gas volatilized in this way is discharged to the outside after passing through the filter (9) to block the water drops in the suction action of the fan (7).

On the other hand, the sprayed and dechlorinated water particles are combined with each other and collected at the bottom of the dechlorination tank 5 and flows to the detergent inlet 12 through the washing water outlet 4 as shown in FIG.

Accordingly, the dechlorinated wash water is joined with the wash water introduced into the detergent input tank through the washing water inlet 3 formed on the detergent input tank 12 and flows into the laundry tank 1.

At this time, the washing water outlet 4 of the dechlorination tank (5), so that the amount of wash water flowing out through the washing water outlet 4 is greater than the amount of washing water sprayed through the ejector (6) In order to have a larger flow path cross-sectional area than the washing water inlet (3).

This is to allow the chlorine component of tap water to evaporate while tap water is sprayed or sprayed into the dechlorination tank 5 by the ejector 6, and when the amount of tap water discharged through the outlet is smaller than the tap water quantity to be injected, the dechlorination tank This is because the internal pressure is formed in (5) so that the tap water is different in the dechlorination tank, thereby reducing the spraying effect by the ejector, thereby lowering the evaporation performance of the chlorine component.

As described above, the present invention is to remove the chlorine component remaining in the wash water flowing into the washing tank (1) on the water supply path to prevent discoloration of colored clothing due to the wash water inconvenience of using the washing machine due to the discoloration of clothing Can be solved.

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.
