Description

Washing water supply device and washing method using same {SUPPLYING INSTALLATION OF WASHING WATER AND WASHING METHOD}

The present invention relates to a washing method of a detergent-free washing machine, and more particularly, in order to spray the basic washing water supplied from the electrolysis device in order to prevent re-contamination occurring during the washing process, to set the injection timing of the basic washing water The present invention relates to a washing water supply device and a washing method using the same.

In general, the electrolysis apparatus used in the detergent-free washing machine has a role of generating basic wash water and supplying it to the reservoir. To this end, electrolytes such as sodium chloride (NaCl) and sodium carbonate (Na ₂ CO ₃ ) are introduced into the electrolysis device. Electrolytes dissolve in tap water and induce chemical reactions through electrolysis devices.

Such an electrolysis device is shown in FIG. As shown, the electrolyte chamber housing 103 having a predetermined shape for accommodating the electrolyte to generate electrolytic water through an electrolysis reaction with tap water. In addition, a washing-water bag housing 105 having a shape corresponding to the electrolyte housing 103 and generating basic wash water through an electrolysis reaction with tap water is configured. In addition, an ion exchange membrane 109 is mounted between the electrolyte chamber housing 103 and the laundry chamber housing 105.

For electrolysis, a positive electrode plate 107 is mounted between the electrolyte chamber housing 101 and the ion exchange membrane 109. The negative electrode plate 111 is mounted between the washbasin housing 105 and the ion exchange membrane 109. At this time, DC power is supplied to each electrode plate, and a control device for power control is installed.

The controller controls the electrolyte to be introduced between the ion exchange membrane 109 and the positive electrode plate 107. Under the control of the controller, the electrolyte operates for electrolysis for a predetermined time. This applies the current / voltage to the positive electrode plate 107 and the negative electrode plate 111 so that the electrolysis is performed in the electrolyte chamber housing 103 and the laundry chamber housing 105.

This produces carbon dioxide, carbon monoxide and oxygen electrolyzed from sodium chloride and sodium carbonate and water in the electrolyte room. Hydrogen is generated in the laundry bag, and product gas is discharged through the inlet and the gas outlet, respectively.

The ion exchange membrane 109 supplies sodium ions (Na +) and hydrogen ions (H +) to the laundry bag, and provides hydroxide ions (OH −) to the electrolyte room. This produces basic wash water. The basic wash water is supplied to a washing tank, diluted with tap water and washed.

Basic washing water used in the washing administration is supplied to the washing tank by a control device in a certain amount, and tap water is also supplied to the washing tank in a certain amount. After that, the control device operates the pulsator to perform the washing operation. After completion of the initial wash administration, an intermediate dewatering stroke is carried out, and the basic wash water and the washed wash water are discharged prior to dehydration. Therefore, the contaminants adsorbed on the laundry are removed by centrifugal force in the dehydration stroke.

However, even when the washing operation is completed through the washing operation and the main water rinsing mode through the dehydration step, contaminants remain in the laundry. This is because when the washed wash water is discharged, contaminants deposited in the washed wash water are deposited on the laundry. As a result, the laundry is extremely likely to be recontaminated after washing.

This recontamination of laundry is a fundamental factor that reduces the quality of the product, and a way to block it will have to be sought.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a washing water supply device and a washing method using the same that can prevent contaminants remaining in the laundry through the washing administration of the detergent-free washing machine. have.

And a wash water injector comprising a first pump for introducing wash water into the storage tank and a second pump for spraying the basic wash water loaded on the storage tank.

Washing method using a washing water supply apparatus according to a second aspect of the present invention for achieving the above object, a) receiving a tap water from the washing water supply device to perform a pre-wash by devoting a part of the total washing time ; b) entering an intermediate dewatering stroke and spraying the basic wash water into the laundry for a predetermined time before the end of the intermediate dewatering stroke; c) entering the washing operation, while stirring for the remaining time of the total washing time and spraying a predetermined amount of the basic washing water into the laundry; d) entering the dehydration stroke, while dehydrating at a low speed for a predetermined time and simultaneously spraying a predetermined amount of the basic washing water onto the laundry; e) spraying a predetermined amount of tap water after a predetermined time has elapsed in d); And f) operating the rotational speed of the washing tank in the normal range.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. 2 is a perspective view of a washing water supply device constructed in accordance with the present invention. 3A and 3B are flowcharts for explaining the operation of FIG. 2. 4 is a configuration diagram for the control of FIG. 2. As shown, an electrolysis device 201 for generating basic wash water by electrolysis and a storage tank 203 for diluting and spraying the basic wash water generated from the electrolysis device 201 to a predetermined volume. Is made of.

The storage tank 203 and the electrolysis device 201 may be installed in close proximity or one side may be coupled. The storage tank 203 is equipped with a water supply pipe 221 for receiving tap water from the side. A water supply solenoid 229 for fastening the amount of water supply is fastened to an end of the water supply pipe 221.

A drain pipe 227 for drainage and a drain solenoid 225 for drainage control are formed at a lower end of the storage tank 203. The side of the storage tank 203 is equipped with a first pump 207 for receiving the basic wash water generated from the electrolysis device 201. In addition, the side of the storage tank 203 is provided with a second pump 213 for spraying the washing water in the tank. The second pump 213 is connected to the nozzle pipe 215 having the nozzle 217.

A water level sensor 211 is mounted on an upper end of the storage tank 203, and the first pump 207 and the electrolysis device 201 are fastened through the delivery pipe 205. The output port of the first pump 207 supplies the wash water to the storage tank 203 through the connecting pipe 209.

As shown in FIG. 4, a program memory 405 in which a program according to a washing stroke and a spray control of the washing water supply device 200 are mounted, and a microcomputer 401 for controlling the system according to the program. It consists of.

The microcomputer 401 is connected to the water level sensor 211 as an input port, the first pump 207, the second pump 213, the water supply solenoid 229 through the driver 407 to the output port of the microcomputer 401 ) And the drain solenoid 227 are connected. In addition, the microcomputer 401 is connected to the washing stroke driver 409 for system control of the washing machine according to the washing stroke.

Referring to Figure 3a, 3b the operation of the present invention will be described.

The microcomputer 401 controls the preliminary washing process through the washing administration driver 409 according to the prewashing mode stored in the program memory 405 (S301). In the pre-cleaning stroke, the microcomputer 401 operates the water supply solenoid 229 through the driver 407. The tap water is supplied to the storage tank 203 through the water supply pipe 221.

The microcomputer 401 receives the signal detected by the water level sensor 211 by enabling the input port. When the microcomputer 401 determines that the water level of the storage tank 203 reaches the reference value through the water level sensor 211, the second pump 213 is turned on. The tap water loaded in the storage tank 203 is sprayed into the washing tank through the nozzle 217.

When a predetermined amount of tap water reaches the washing tub, preliminary washing is performed through the washing stroke driver 409. At this time, the washing time is generally about 1/3 of the washing time. When the microcomputer 401 recognizes that about one third of the washing time has elapsed, the microcomputer 401 enters the intermediate dehydration mode. The dehydration time T required in the intermediate dehydration mode is stored in the program memory 405.

The microcomputer 401 performs a count at the same time as the start of intermediate dehydration to determine whether the current intermediate dehydration remains for a predetermined time (K). That is, it is determined whether the current intermediate dehydration time is greater than (T-N). Where N is (T-K).

The microcomputer 401 determines whether the (T-N) time is smaller than the dehydration time that has elapsed so far (S305). If the (T-N) time is smaller than the dehydration time elapsed to the present, it is determined whether (T-N) is '0' (S306). If it is not '0', and feeds back to S305, and if the (T-N) time in S305 is greater than the dehydration time elapsed up to now, the microcomputer 401 supplies power to the electrolysis device 201 (S315).

Then, the first pump 207 is operated to introduce the basic wash water generated by the electrolysis device 201 into the storage tank 203 through the delivery pipe 205. The microcomputer 401 determines whether the water level of the storage tank 203 has reached the upper limit through the water level sensor 211 (S317). When the water level of the storage tank 203 reaches the upper limit, basic washing water is injected into the laundry through the nozzle tube 215 by operating the second pump 213 (S319).

It is preferable that the injection quantity of basic wash water is fixed by experimental value.

On the other hand, the microcomputer 401 by intermittently rotating the pulsator of the washing machine to make the basic wash water evenly wet with the laundry can increase the efficiency. When the water level of the storage tank 203 detected from the water level sensor 211 reaches the lower limit (S321), the microcomputer 401 stops the second pump 213 (S323). While repeating the above process and determining that T-N = 0 is determined by S306, the microcomputer 401 terminates the intermediate dehydration operation.

The program memory 405 provides the microcomputer 401 with the program for the present washing administration at the same time as the program of the intermediate dehydration stroke (S307). In the preliminary washing operation, the washing time is one third of the normal washing time, and thus, the washing process is normally performed for two thirds of the washing time (S309). This washing administration is finished and enters the dehydration administration (S313).

Basic washing water is sprayed into the laundry for a predetermined time in the initial stage of the dehydration stroke. To this end, the microcomputer 401 starts an inverse count for the predetermined time through the internal counter (S325). The microcomputer 401 supplies power to the electrolysis device 201 (S327). And dehydration of low speed is performed according to dehydration stroke. The microcomputer 401 determines whether the water level of the storage tank 203 is greater than the upper limit through the water level sensor 211 (S333). As a result of determination, the microcomputer 401 outputs a control signal for operating the second pump 213 and the first pump 207 to the driver 407 (S329).

The microcomputer 401 continuously detects the water level sensor 211 to determine whether the water level of the storage tank 203 is smaller than the lower limit (S335). As a result of the determination, when it is smaller than the lower limit, the microcomputer 401 turns off the second pump 213 and the first pump 207 (S331). The microcomputer 401 controls the operation of the second pump 213 as described above, and determines whether the reverse count reaches '0' (S337). As a result of the determination, if it does not reach '0', S329 to S335 are repeated.

As a result of the determination, when it reaches '0', the microcomputer 401 turns off the first pump 207 and the second pump 213 including the electrolysis device 201 to cut off the power (S339).

After that, the microcomputer 401 enters the water rinsing cycle (S341). In the water rinsing stroke, the microcomputer 401 turns on the water supply solenoid 229 to allow the tap water to be loaded into the storage tank 203. The microcomputer 401 operates the drain solenoid 225 to discharge the tap water loaded in the storage tank 203 into the drain pipe 227.

The tap water is dropped into the laundry in the dehydration tank, and the main water rinse is performed from the low speed dewatering stroke. The water rinsing is performed for a predetermined time, and the microcomputer 401 checks the elapsed time according to the water rinsing. When the main water rinsing stroke is completed (S343), the microcomputer 401 increases the dehydration rotation speed (S345). The spin speed is the normal spin speed. When the dehydration stroke is completed, all the washing operations of the washing machine are finished.

As described above, the washing water supplying apparatus and the washing method using the same according to the present invention constitute a storage tank having a predetermined capacity in the vicinity of the electrolysis device, and the tap water or basic washing water loaded in the storage tank is stored in the storage tank of the washing machine. After the injection device is installed for spraying, basic washing water is sprayed by deciding part of the intermediate dewatering time in the washing operation of the washing machine, and spraying and rinsing the basic washing water by deciding part of the main dehydration time. After the addition, the main dehydration operation is performed, thereby obtaining an effect of preventing contamination remaining during the discharge of the wash water after washing.

What has been described above is only one embodiment for carrying out the washing water supply apparatus and the washing method using the same, the present invention is not limited to the above-described embodiment, as claimed in the following claims As described above, any person having ordinary knowledge in the field of the present invention without departing from the gist of the present invention will have the technical spirit of the present invention to the extent that various modifications can be made.
