The present invention relates to a washing machine, and more particularly, to a washing control method of a washing machine that can wash footwear such as sneakers.

Generally, a washing machine is a device having a basic principle of driving a rotary blade (called a pulsator) or a stirring blade (edgeator) by using a motor to form a stream of water, which causes the stream of water to impact the laundry.

1 is a flowchart illustrating a washing method of such a washing machine. As shown in Figure 1, the general washing method of the washing machine is largely composed of a washing stroke (S10), up to five rinsing strokes (S20-S60), a dehydrating stroke (S70) and a stop process (S80). The washing stroke (S10) is again controlled in the order of water supply process (S11) for watering up to the water level set by the user and the pulsator left turn → stop → right turn → stop → left turn while varying the time according to the set water level and the type of laundry It consists of a main washing process (S12) to stir the laundry at low speed. As an example of this main washing process (S12), when the water level is set to a high water level, a maximum turn of about 15 minutes is performed in the order of left turn 2.2 seconds → stop 1 second → right turn 2.2 seconds → stop 1 second. The maximum duration is 14 minutes with 1.5 seconds each and 1 second stop time. When the washing stroke (S10) is finished, the rinsing stroke (S20-S60) is performed, and the rinsing stroke is basically performed two or three times depending on the set water level, and added three or two times according to the user's selection. It is programmed to run up to five times. Each process of the rinsing stroke (S20-S60) is the main washing process (S12) or draining process (S21) for draining the washed water after the rinsing process is finished, intermittently rotating the washing tank intermittently at high speed while supplying the washing tank The dehydration process (S22), the dehydration process (S23) to remove the water contained in the laundry by rotating the washing tank at high speed before performing the rinsing process (S26) to be described later, the stop process (S24) to stop the washing tank, the setting in the washing tank It consists of a water supply process (S25) for supplying water to the water level and a rinsing process (S26) for rinsing the laundry while stirring the pulsator from side to side. In this way, when all of the rinsing cycles (S20-S60) of the predetermined number of times are completed, the dehydration stroke (S70) is performed. The dehydration stroke (S70) again drains the washing water completely (S71), intermittent dehydration as described above. The process (S72) and while rotating the wash water at high speed consists of a main dehydration process (S73) for removing the wash water contained in the laundry by centrifugal force. The above-mentioned intermittent dehydration processes (S22, ..., S72) is a process for correcting the tangled and stagnant laundry by the main washing process (S12) and each rinsing process (S26, ...).

However, the laundry such as clothing that can be washed by a general neutral detergent is effectively washed by the conventional washing method as described above, but the footwear such as sneakers or indoor shoes is generally used according to the difference in material and form. There was a problem that the laundry washing method can not remove the dirt easily and effectively.

Accordingly, the present invention has been made in view of the above point, and an object thereof is to provide a washing control method of a washing machine that is capable of washing footwear such as sneakers.

Washing control method of the washing machine according to the present invention in order to achieve the above object is based on the detection result of the water level detection unit to supply the washing water to the water level set by the user to the washing machine to perform washing by stirring the pulsator from side to side In the process, receiving the selection of whether to perform the washing of the sneakers from the user, if the washing of the sneakers is selected, the process of performing the initial washing by driving the pulsator for a predetermined time after the water supply to the initial level of the laundry is locked, the initial When the washing process is completed, the process of soaking the laundry in the washing water for a predetermined time, and when the soaking process is completed, the water supply to the set water level set by the user and the process of performing the main washing by driving the pulsator It is characterized by.

Hereinafter, the configuration and the effect according to the preferred embodiment of the present invention will be described in detail.

2 is a control block diagram of a washing machine to which the laundry control method of the present invention is applied. As shown in Figure 2, the configuration of the washing machine applied to the method of the present invention is the control unit 10 for controlling the overall operation of the washing machine, washing stroke, rinsing stroke and dehydration stroke, the selection of the desired function and the selected function of the Function selection unit 20 for setting the execution time, water level setting unit 30 for setting the desired level of the wash water, water level detection unit 40 for detecting the water level of the water to be washed, laundry weight A water supply valve driver 60 for opening and closing the water supply valve 61 under the control of the weight sensing unit 50 for detecting a water supply, the water supply valve 61 for supplying the wash water into the tank and the control unit 10 connected to the water supply source. ), The drain motor 71 for driving the drain motor 71 under the control of the drain motor 71 and the control unit 10 for draining the wash water, and a pulsator at a predetermined time period during the washing or rinsing process. Reverse rotation and dehydration The washing motor 81 for rotating the washing tank at high speed and the washing motor driving unit 80 for driving the washing motor 81 under the control of the control unit 10.

In the above-described configuration, the water level detection unit 40 can be well implemented as a pressure sensor, and the setting of the water level can be set in one of five levels of high, medium, low, small, and minimum, and the weight detection unit 50 is one example. It is well implemented as a load cell, which is bonded to a detection plate called a distortion gauge that converts distortion into a change in resistance around a forced cylinder called a distortion object, which is coupled to the load button. Therefore, when a load is applied to the load button, the weight is applied to an object in which distortion occurs, so that distortion occurs in proportion to the weight, and the electric resistance of the distortion gauge changes according to the amount of distortion, so the current flowing changes. The controller 10 detects the weight by converting the signal into a digital electric signal.

3 is a flowchart showing a washing control method according to the present invention. Referring to FIG. 3, the present invention will be described below. First, since the user usually washes footwear such as sneakers separately from general clothes laundry, and puts laundry such as sneakers to be washed in the washing tank and selects the sneaker washing course through the function selection unit 20, the washing administration ( S100), the rinsing stroke (S120-S150), the dehydration stroke (S160) and the stop process (S170) is performed.

The washing administration (S100) first detects the weight of the shoe to be washed in step S102, and determines the amount of laundry to be washed based on the weight of the shoe as a result of the detection. In addition, in step S104, a predetermined amount of detergent set in advance according to the amount of laundry determined according to the detection result of step S102 is introduced into a laundry tank containing laundry. Further, in step S106, the water level corresponding to a predetermined ratio of the water level set through the water level setting unit 30 from the user, for example, up to a water level equal to 1/2 of the water level set by the user (this is called an initial water level). In step S108, the pulsator is controlled in the order of left turn → stop → right turn → stop → left turn while varying the time according to the set water level and the amount of laundry, and the laundry is stirred left and right. The initial washing process (priming laundering process) is performed to remove dirt from the mud on the back surface. At this time, the initial washing by dissolving the detergent in the wash water of the water level lower than the set level is to make it easy to remove the dirt, such as the surface of the shoe with a concentration of detergent.

In step S110, during the initial washing in step S108, a soaking process is performed to remove strays that are not easily removed such as shoe soles or shoes, which is a predetermined time for washing the laundry in water in which detergent is dissolved. For example, soak it for 30 minutes to 1 hour and it will be called out completely. When a predetermined set time of the step (S110) has elapsed, the water supply process is performed in step (S112), in this case, the water supply valve 61 to perform water supply to the water level set by the user through the water level detection unit (40). When the water supply is completed to the set water level in step S114, the water supply valve 61 is turned off, and the pulsator is rotated forward and backward in the order of one example of left turn → stop → upturn → stop → left turn. By generating a certain water flow, the stained oil emulsified by the detergent in the soaking process is completely separated from the laundry to complete the washing process.

When the washing operation is finished, the rinsing process is performed in step S120, which may be performed twice or three times according to the set water level, and may be added two or three times as an example, depending on the user's selection. have. This rinsing stroke drives the drain motor 71 as in step S122 to drain the washing stroke or the rinsing stroke and the turbid wash water (draining process), and when the draining is completed, the drain motor 71 The drive is turned off and in step S124 the washing motor 81 is driven for a predetermined time to rotate the washing tank to remove water contained in the sneakers (dehydration process), and in step S126 the washing motor 81 for water supply. The driving of the off to stop the washing tank. In step S128, the water supply valve 61 is opened to supply water to the washing tank (water supply process), and in step S130, the water level of the washing tank is set to a predetermined level based on a signal provided from the water level detection unit 40. When the water level is reached and the set water level is reached, the pulsator is repeatedly operated in the order of left turn → stop → right turn → stop → left turn to remove the detergent and the remaining time from the laundry.

In this way, when all the rinsing cycles of the predetermined number of times are finished, the dehydration stroke is performed in step S160, which in turn drives the drain motor 71 in step S162 to completely drain the wash water (drainage process). At S164, the drive of the drain motor 71 is turned off, and the washing motor 81 is driven to rotate the washing tank at high speed while dehydrating the water contained in the laundry by centrifugal force.

As described above, by the washing control method of the washing machine according to the present invention, shoes such as sneakers and indoor shoes can be easily and effectively washed using a washing machine, thereby eliminating the inconvenience of having to wash the hands by the user. There is this.
