As such, the reason for completely dissolving the detergent and the disinfectant before adding the laundry is to prevent the laundry from being damaged by the disinfectant. That is, when the thick disinfectant is in direct contact with the laundry, there is a risk of discoloration or damage to the cloth. In order to prevent this, the disinfectant and the detergent are completely supplied by driving the pulsator 32 by supplying a predetermined amount of water to the rotating tub 30. So that it can be dissolved.

Next will be described the operation and effect of the detergent input device according to the invention configured as described above.

First, when the user withdraws the detergent container 62 from the casing 61, the sterilant container 63 mounted on the upper side of the storage space is exposed to the outside, and the detergent for washing and the sterilizing agent for sterilizing action are added thereto.

That is, as shown in FIG. 5, when the front part of the disinfectant container 63 is lifted upward so that the upper part of the detergent container 62 is completely opened, the powder detergent A is stored in the storage space 621 of the detergent container 62. ) Can be added easily. After the powder detergent A is put into the detergent container 62, as shown in FIG. 6, the sterilant container 63 is lowered again until the fixing protrusion 651 is seated in the recess 652. Is maintained. Subsequently, an appropriate amount of the disinfectant (B) is added to the disinfectant container 63 arranged to be partitioned with the storage space 621, and then the detergent container 62 is pushed in to keep it stored inside the casing 61. do. As such, when the detergent container 62 is pulled out, the sterilant container 63 installed separately is visible, so that the user can easily recognize that the naked eye and perform a sterilization function, and the upper part is opened. Through the disinfectant container 63, an appropriate amount of disinfectant (B) can be added.

In this state, when the external power is applied through the power input button 71 and the sterilization course signal is input to the control unit 70 through the sterilization course button 72, the water supply valve 53 is opened so that the water is dispensed in the detergent container 62. The first water supply is supplied to the rotating tub 30 while passing through). That is, a part of the water falling into the detergent container 62 through the water supply port 612 is supplied through the discharge port 631 together with the sterilant B while passing through the sterilant container 63, and the other part of the detergent container 62. While passing through the storage space 621 is supplied with a powder detergent (A). At this time, since the bottom surface front part of the sterilant container 63 consists of the curvature surface 633, the sterilant B is wash | cleaned easily in the water which flows in and is discharged | emitted. This primary water supply is made to the extent that the detergent (A) and the disinfectant (B) are sufficiently dissolved, which is programmed in advance in the control unit 70.

When the first water supply is completed, by rotating the pulsator 32 for a predetermined time, that is, 1 to 2 minutes through the drive unit 40 including the motor 41 and the power transmission device 42, the detergent A And disinfectant (B) are completely dissolved in the rotating tank (30). Thus, completely dissolving the detergent (A) and the sterilizing agent (B) before the laundry is put in order to prevent the laundry damage by the sterilizing agent (B) as described above.

Then, when the laundry is put into the rotating tub 30 and the washing machine lid 54 is closed, the rotating tub 30 is temporarily rotated to detect the weight of the laundry, and the water supply valve 53 is opened again to the required amount for washing. The second water supply of is performed. At this time, since the disinfectant B is completely dissolved in the predetermined time driving of the pulsator 32 together with the primary water supply, no damage to the cloth occurs even when the dissolved disinfectant contacts the laundry.

When the second water supply is completed, washing water is formed by driving the pulsator 32, and washing is performed. Since the disinfectant (B) is completely dissolved in the washing water together with the detergent (A), the washing and sterilization are performed at the same time. Work is done.

As a result, the laundry is sterilized by the disinfectant (B) as well as the laundry by the detergent (A) to improve the overall washing performance, as well as wash water between the rotary tank 30 and the water tank 20 dehydration hole (31) Since they are also distributed through the sterilization, the odor causing substances are removed when washing is completed to prevent the occurrence of odor. At this time, the user can easily recognize that the sterilizing function is added to the washing machine because the sterilant container 63 is exposed to the outside when the detergent container 62 is drawn out. Sterilizer (B) can be added.

Next, a control method of the washing machine according to the present invention configured as described above will be described with reference to FIG. 7.

First, the user inputs the detergent (A) and the disinfectant (B) into the detergent container 62 and the sterilant container 63 (step S1), and then the sterilization course signal is input to the controller 70 through the sterilization course button 72. (Step S2), the control unit 70 performs the first water supply by opening the water supply valve 53 through the water supply valve driver 73 (step S3). In step S3, a small amount of water is supplied so that the detergent A and the disinfectant B introduced together with the water are sufficiently dissolved in the rotating tank 30. When the water supply is completed in step S3, the pulsator 32 is driven for a predetermined time (1 to 2 minutes in this embodiment) to dissolve the detergent A and the sterilizer B, It is detected whether the driving time has elapsed (step S5). Step S5 is a step of preventing the laundry damage by the sterilant (B), is to put the laundry in a state in which the disinfectant (B) completely dissolved.

As a result of the detection in step S5, if the predetermined time has not passed, the pulsator 32 is continuously driven, and if the predetermined time has elapsed, the alarm driver 76 generates a drive buzzer to notify the laundry input (step S6).

After the laundry is put into the rotating tub 30 by the user following step S6, the closed state of the lid 54 of the washing machine is sensed (step S7). If the lid 54 is opened in step S7, the process returns to step S6. In this case, the washing stroke is not performed when the lid 54 is opened. And when the lid 54 is closed in step S7, the rotary tub 30 temporarily detects the weight of the laundry put into the rotary tub 30 through the rotary weight sensing unit 75 (step S8), the weight of the laundry Accordingly, the second water supply to which the predetermined amount of washing water is supplied to the controller 70 is performed (step S9).

Then, after the step S9, the pulsator 32 is rotated forward and backward to perform a general washing operation (step S10). Since the disinfectant (B) is dissolved together with the detergent (A) in the washing water, washing of the laundry as well as sterilization is performed. The action is parallel. At this time, since the disinfectant (B) is sufficiently dissolved in the wash water through a dissolution step (S4) in which the first water supply step (S3) and the pulsator 32 are driven for a predetermined time, even when directly in contact with the laundry. This prevents laundry damage. In addition, since the rotating tank 30 and the water tank 20 are also sterilized by the dissolved sterilizing agent (B), the occurrence of odor in the washing machine is prevented.

As described above in detail, according to the detergent input device of the washing machine and the control method of the washing machine according to the present invention, after the detergent and the disinfectant are simultaneously added to the detergent input device provided with a storage space for detergent and the sterilizer container separately, By supplying a small amount of water into the rotating tank through the secondary water supply and dissolving the laundry continuously, the washing operation is performed, and the washing operation is sterilized as well as the laundry, thereby improving reliability of the washing machine. At this time, the laundry is in contact with the first water supply and the disinfectant completely dissolved through the dissolution step to prevent laundry damage such as discoloration. In addition, there is an advantage that the odor generated in the washing machine is prevented by the sterilization agent dissolved in the wash water and also the rotary bath and the water tank.
