The present invention relates to a washing machine, and more particularly, to a detergent supply method and apparatus for a washing machine in which powder detergent is efficiently dissolved and supplied.

In general, a washing machine is a device that automatically performs a series of washing, rinsing, and dehydration by putting laundry, water, and an appropriate amount of detergent in a washing tank and giving the impact of mechanical water flow to the laundry. It can be divided into powder detergent and liquid detergent.

Referring to the example of the washing machine based on Figure 1, the top panel 12 is installed on the upper portion of the cabinet 10, the water supply valve 14 for supplying water to the top rear of the top panel 12 is mounted In front of the top surface of the top panel 12, a control panel 16 capable of inputting a driving signal of the washing machine is mounted. In the cabinet 10, a reservoir 18 capable of storing water is installed, and a shower ring 20 is mounted on the upper portion of the reservoir 18, and the shower ring 20 is provided from the water supply valve 14. Water will be supplied.

In addition, the washing tank 22 is rotatably installed inside the water storage tank 18, and a pulsator 28 is provided at the bottom of the washing tank 22 by a gear device 26 transmitting a driving force of the motor 24. Is installed to be rotatable. Therefore, when the user sets the washing function desired by the user, the pulsator 28 is rotated by the gear device 26 which transmits the driving force of the motor 24, and water flow is generated by the rotation of the pulsator 28. Thus, the laundry is washed.

On the other hand, the washing machine uses a detergent dissolving device to improve the washing efficiency of the laundry, the detergent dissolving device is to dissolve the powder detergent by the water supplied to the washing tank.

In the conventional detergent dissolving apparatus of the washing machine, as shown in FIG. 2, a water channel 30 is formed on one side of the top panel 12 so that the water supply valve 14 and the washing tank 22 can be connected to each other. A drawer 32 is mounted in the slide 30 so as to be pulled out in a slide manner, and a nozzle 34 is mounted on the upper portion of the channel 30 so that water is supplied above the drawer 32. Therefore, when the washing stroke of the washing machine is performed while the powder detergent is put into the drawer 32, the water is supplied from the water supply valve 14 to the water channel 30 while the powder detergent in the drawer 32 is removed. It is dissolved and put into the washing tank 22.

By the way, the detergent dissolving apparatus of the conventional washing machine as described above, since the powder detergent of the drawer 32 is dissolved only by the water supplied from the water supply valve 14, the powder detergent is not properly dissolved, so that the dissolution rate is greatly reduced and washed. And there was a problem that the rinsing efficiency is also relatively low.

In addition, the powder detergent is hardened while remaining in the drawer 32, which causes a problem in the supply of the detergent, the powder powder has a cumbersome and inconvenient problem that the user must remove directly.

On the other hand, the powder detergent can be improved the washing efficiency only by adding an appropriate amount depending on the water level. That is, the powder detergent is to be put into the drawer 32 of the washing amount of the laundry detergent once to match the set water level according to the washing level of the laundry, but since the supply of the powder detergent is to be carried out by the user arbitrarily It is very difficult and difficult to supply the amount properly adjusted, which causes waste of detergents and has been an uneconomical problem. In addition, when the detergent is excessively added, there was a problem that acts as a cause of contaminating the water quality.

The present invention has been made to solve the above-mentioned conventional problems, it is an object of the present invention to provide a detergent supplying method and apparatus for a washing machine to improve the dissolution rate of powder detergent.

Another object of the present invention is to provide a detergent supplying method of a washing machine and an apparatus thereof, which are made easy to use.

First, as shown in FIG. 1 and FIG. 3, the top panel 12 is installed at the upper part of the cabinet 10, and the detergent solution in which powder detergent is dissolved in water can be stored on one side of the top panel 12. The container 40 is embedded to have a storage chamber 42. The vessel 40 has a water supply valve 14 and an inlet 44 leading to it, and an outlet 46 for discharging the detergent liquid to the washing tank 22. The storage chamber 42 of the vessel 40 has a lid 48. Is opened and closed by. Here, the inlet port 44 is formed on the upper side of one side of the container 40, the outlet 46 is preferably formed perpendicular to one side of the lower surface of the container (40).

In addition, the stirrer 50 is installed in the storage chamber 42 of the container 40 so that the powder detergent and water can be dissolved to dissolve the powder detergent. The stirrer 50 is mounted in the lower portion of the vessel 40 so that the motor 52 has the shaft 54, and the shaft 54 of the motor 52 is adjacent to the lower surface of the vessel 40 so as to be adjacent to the first magnet 56. ) Is mounted. The second magnet 58 is placed on the bottom of the container 40 so as to be rotatable corresponding to the rotation of the first magnet 56, and the rotational position of the second magnet 58 is installed at the bottom of the container 40. Regulated by the lattice housing 60. That is, the second magnet 58 is wrapped by the lattice housing 60 such that its rotational position is restricted at the bottom of the container 40. Here, the first and second magnets 56 and 58 are preferably manufactured in a rod shape, and one of the first and second magnets 56 and 58 may be made of a magnetic material, for example, an iron plate. . The outlet 46 of the container 40 is equipped with a solenoid valve 62 capable of controlling the supply amount of the detergent liquid.

As shown in FIG. 4, the washing machine of the present invention drives each driving means, for example, the motors 24 and 52, to perform a corresponding function according to the input of the driving signal by the operation of the key matrix 70. Equipped with a microcomputer 80 to control the. The key matrix 70 can be configured by the control panel 16. The microcomputer 70 has a water level sensor 72 that detects the water level of the water supply valve 14, the solenoid valve 62, and the washing tank 22. Are respectively connected.

Referring to the detergent supply method of the washing machine according to the present invention as described above and the operating state of the device as follows.

4 and 5, when the laundry is to be washed, the washing machine is turned on, and powder detergent is put into the storage chamber 42 of the container 40 (S100), and the key matrix 70 is used. Set the water level according to the washing amount by the operation of. At this time, the powder detergent is preferably added to the washing amount of about 5 times based on the high water level.

On the other hand, the washing machine can be divided into high, medium, low and very low water levels. For example, when the washing and dehydrating capacity of the washing machine is about 9-11Kg, the high level is about 10Kg or less, the medium level is about 5Kg or less, and the low level is about 3Kg or less. In addition, the minimum water level can be arbitrarily set by the operation of the key matrix 70 when the laundry is very small, for example, about 1 kg or less.

In addition, when the water level according to the washing amount is set and input, the microcomputer 80 sets the supply amount of the detergent liquid according to the set water level (S102). That is, the microcomputer 80 is set to match the supply amount of the detergent liquid by a predetermined program according to the set water level. Thus, since the detergent liquid can be properly supplied according to the level of the washing machine, waste of the detergent can be prevented and the amount of the detergent can be reduced and economical, and water pollution due to excessive use of the detergent can be prevented.

Then, after the supply amount of the detergent liquid is set, the microcomputer 80 determines whether a washing signal by the operation of the key matrix 70 is input (S104), and if it is determined that the washing signal is not input, the corresponding mode is determined. It is executed (S106). If it is determined that the washing signal is input, the microcomputer 80 opens the water supply valve 14 and supplies water to the storage chamber 42 and the washing tank 22 of the container 40, respectively (S108). At this time, the water supply amount through the water supply valve 14 can be adjusted by the control of the microcomputer (80).

On the other hand, when water is supplied to the storage chamber 42 of the container 40, the microcomputer 80 drives the stirrer 50, the water and powder detergent is stirred by the drive of the stirrer 50, the powder detergent Dissolve (S110). That is, when the first magnet 56 is rotated together with the shaft 54 by the driving of the motor 52, the second magnet 58 corresponds to the rotation of the first magnet 56 so that the bottom of the container 40 is rotated. Since the water and the powder detergent is stirred while rotating in, the powder detergent is efficiently dissolved. Here, the second magnet 58 is wrapped by the lattice housing 60 to regulate the rotational position, and the second magnet 58 is embedded in the storage chamber 42 of the container 40 so that the motor 52 Since it can be rotated independently, it is possible to effectively prevent leakage due to the installation of the stirrer (50). In this way, the powder detergent is dissolved efficiently by driving the stirrer 50, so that the dissolution rate is improved, and the washing and rinsing efficiency is improved in proportion to the dissolution rate being improved. In addition, the powder detergent is not dissolved and can be effectively prevented from being hardened, making it convenient to use.

In addition, after the microcomputer 80 dissolves the powder detergent by driving the stirrer 50, the solenoid valve 62 is opened to wash the detergent liquid at a supply amount set through the outlet 46 of the container 40. It is supplied to (S112). At this time, the supply amount of the detergent liquid can be controlled by controlling the opening time of the solenoid valve 62, the opening time of the solenoid valve 62 corresponds to the power application time of the solenoid valve 62. That is, while power is applied to the solenoid valve 62, the discharge port 46 is opened to supply the detergent liquid. When the power supply of the solenoid valve 62 is cut off, the discharge port 46 is closed to stop the supply of the detergent liquid.

Then, the microcomputer 80 determines whether the supply amount of the detergent liquid has reached the set supply amount (S114). If it is determined that the supply amount of the detergent liquid has not reached the set supply amount, the microcomputer 80 continues to supply the detergent liquid, and the detergent liquid is supplied. When it is determined that the supply amount reaches the set supply amount, the supply of the detergent liquid is stopped (S116).

On the other hand, the water level of the washing tank 22 is detected by the water level sensor 74 is input to the microcomputer 80, the microcomputer 80, the water level of the washing tank 22 input from the water level sensor 74 reaches the set water level. It is determined whether or not (S118). If it is determined that the water level has not been reached, the water supply is continued. If it is determined that the water level is reached, the pulsator 28 is rotated by the driving of the motor 24 to wash the laundry (S120).

The above embodiments are merely illustrative of the preferred embodiments of the present invention, and the scope of application of the present invention is not limited to these, and may be appropriately changed within the scope of the same idea. For example, the shape and structure of each component specifically shown in the embodiment of the present invention can be modified.

As described above, according to the detergent supply method and apparatus of the washing machine according to the present invention, since the powder detergent is efficiently dissolved by the stirring of the stirrer and supplied in an appropriate amount according to the water level, the washing and rinsing efficiency is not only improved. This prevents the hardening of the powder detergent and makes it convenient to use. In addition, the amount of detergent is reduced and economical, it is possible to prevent water pollution.
