A Controlling Method of a Washing Machine

The present invention relates to a control method of a washing apparatus capable of washing between the back of the drum and the back of the tub.

In general, the laundry machine refers to a device for washing or drying clothes or the like. Here, one washing apparatus is a concept including a device capable of performing only a washing or drying function or performing both washing and drying functions.

On the other hand, in recent years, a steam supply device is provided, and washing machines equipped with a refresh function such as wrinkle removal, odor removal, and static electricity removal of clothes, etc., have also been popularized.

The conventional laundry machine includes a cabinet forming an exterior, a tub provided inside the cabinet to store wash water, and a drum rotatably provided inside the tub.

On the other hand, looking at the operation of the laundry machine comprising the above-described configuration, first put the laundry into the drum and then supply the wash water and detergent from the outside of the cabinet to the inside of the tub.

Then, when the drum is rotated, the laundry inside the drum rotates and falls inside the drum along the rotation of the drum. In addition, in the process of rotating along the rotation of the drum friction with the wash water stored in the tub to remove the foreign substances in the laundry.

However, when the washing water and the detergent are supplied from the washing apparatus, the foam formed by the washing water and the detergent is filled in the space formed between the drum and the tub.

On the other hand, the foam that fills the space between the drum and the tub contains the components constituting the detergent and foreign substances such as oil grease from the laundry, there is a risk of being adsorbed on the outer peripheral surface of the drum and the inner peripheral surface of the tub.

In the case of the tub, if the above-described foreign matter on the upper surface and the back of the tub other than the lower surface of the tub in contact with the wash water of the inner circumference of the tub can cause corrosion of the components provided on the back of the tub as well as hygiene problems. This can cause problems.

For example, the center of the back of the tub is provided with a sealing member for penetrating the shaft for rotating the drum and preventing leakage of the wash water through the shaft. If the foreign matter is left, corrosion of the sealing may occur. It can also be.

On the other hand, the drum may have the same problem, although the degree is less than that of the tub.

For example, the washing water supplied to the washing machine is supplied to the extent that the part of the drum can be locked so that foreign substances adsorbed on the outer circumferential surface of the drum are removed to some extent through friction with the washing water stored in the tub while the drum is rotating. It may be possible. However, since the wash water supplied to the tub is only a part of the drum that can be locked, if the foreign matter is adsorbed to the rotation center formed on the rear of the drum, there is a problem that there is no way to remove the adsorption of the foreign matter like the tub.

In other words, it may cause corrosion of the components (for example, spider, etc.) of the washing apparatus provided on the back of the drum.

An object of the present invention is to provide a control method of a washing apparatus capable of removing foreign matters that may be adsorbed on an outer rear surface of a drum and an inner rear surface of a tub to which washing water does not contact.

In this case, the drum rotation step may be characterized in that the washing water stored in the tub rotates at a speed that can reach the upper inner peripheral surface of the tub.

In addition, the drum rotation step may alternately perform the forward and reverse rotation.

In addition, the control method of the laundry machine of the present invention may further include a detergent supplying step of supplying detergent to the washing water following the washing water supplying step.

In addition, the control method of the laundry machine of the present invention may further include a soaking step, which is provided before the drum rotating step, soaking foreign matters on the rear surface of the drum and the inner side of the tub.

In this case, the soaking step may be characterized in that the drum continues to rotate for a predetermined time.

In addition, the soaking step may be characterized in that the drum is called back by repeatedly rotating and stopping the drum.

In addition, the control method of the laundry machine of the present invention may further include a soaking water supply step provided before the soaking step to supply soaking water to the inside of the tub.

In addition, the control method of the laundry machine of the present invention may further include a heating step of heating the soaked water following the soaked water supplying step.

Although not shown, a door-like configuration may be provided on the upper surface of the cabinet 1 to communicate with the detergent box 8.

The heater 9 is provided on the bottom of the tub 2 to heat the washing water supplied to the tub. The washing water is heated before the washing water is sprayed on the outer rear surface of the drum and the inner rear surface of the tub through the sprayer 6, so that foreign matters that may be formed on the outer surface of the drum and the inner surface of the tub are called. By spraying the cleaning power can be improved.

Figure 3 is a procedure showing a control method of the laundry machine according to the present invention.

Referring to each step of the control method of the present invention with reference to Figure 3, the user may include a course selection step (S10) for inputting a command for cleaning the drum outer back and the tub inner back. Therefore, if the user wants to wash between the drum and the back of the tub through the selection button 51 it is possible to input the washing command to the washing machine.

Following the course selection step S10, the soaked water supply step S11 may be performed. The soaked water supply step (S11) means a step of washing water flowing through the supply hose (7).

However, the soaked water supply step S11 may be performed through the wash water supply unit 4.

Subsequent to the soak water supply step S11, a heating step S12 for heating the soak water may be performed. In the heating step (S12) is a step of heating the washing water supplied in the soaking water supply step stored in the tub by the heater 9 by raising the temperature of the washing water supplied for the soaking, the drum outer back (33) and the tub inner It is a step for improving the washing efficiency of the back (23).

Following the heating step (S12), the control method of the laundry machine of the present invention may further include a soaking step (S13). The soaking step (S13) is to heat the wash water supplied in the soaking water supply step (S11) through the heating step (S12) so that the foreign matter that can be formed on the outer back and the tub inner back of the drum to absorb the wash water This is a step for facilitating the removal of foreign substances in the spraying step (S155) to be continued.

On the other hand, in the soaking step (S13), the motor is preferably operated for a predetermined time is controlled so that the drum can continue the rotational movement. This is to allow the entire drum outer circumferential surface to contact the wash water supplied in the soaked water supply step (S11), through which foreign matter adsorbed on the outer rear surface of the drum is easily absorbed and removed by the wash water.

In addition, in the soaking step (S13), the motor is preferably controlled to repeat the stop and the rotation by repeating the stop and the operation for a predetermined time. This is to call the foreign material while the drum stops for a predetermined time while the drum is in contact with the wash water, and then rotates the predetermined angle so that the outer circumferential surface of the drum that is not in contact with the wash water is in contact with the wash water and then stops for a predetermined time to call the foreign matter. to be. Therefore, it is possible to call all the foreign matter adsorbed on the drum through the repetition of the stop and rotation of the drum.

Following the soaking step S13, the drum rotating step S14 and the washing step S15 may be simultaneously performed. This is easy to remove the foreign matter that may be formed on the drum outer back and the tub inner back by spraying the washing water through the spraying portion 6 while the drum rotates the foreign matter changed to a state easy to separate in the soaking step (S13). For sake.

First, the drum rotation step (S14) will be described, the drum rotation step (S14) is a step of rotating at a high speed by the motor (M). In this case, the “high speed rotation” means that the number of revolutions stored in the tub 2 has a rotational speed that can be moved to the upper inner circumferential surface H of the tub 2 by the rotational force of the drum. Through this, the control method of the laundry machine of the present invention can achieve the effect of removing the foreign matter that can be formed on the drum outer peripheral surface and the tub inner peripheral surface.

That is, the drum outer rear surface and the tub inner rear surface is to remove the foreign matter by the injection unit in the spraying step to be described later, the foreign matter of the drum outer peripheral surface 31 and the tub inner peripheral surface 21 can be removed by the rotational force of the drum.

On the other hand, the drum rotation step (S14) may be carried out by alternately performing the forward rotation and the reverse rotation at a low speed. This is to facilitate the removal of foreign matters by spraying the foreign matter washing water formed on the outer surface of the drum in various directions in the injection step (S155) to be described later.

At the same time as the drum rotation step (S14) and washing step (S15) may be carried out, the washing step (S15) may be divided into the washing water supply step (S151), detergent supply step (S153) and spraying step (S155). .

The washing water supplying step (S151) is a step of supplying the washing water to the injection unit 6 through the supply hose (7).

On the other hand, since the supply hose 7 is provided with a detergent box 8, if the user wants to clean the drum outer back and the tub inner back by putting detergent in the detergent box (8) detergent supply step (S153) It is preferably carried out after the washing water supply step (S151).

Following the washing water supply step (S151) and the detergent supply step (S153), the control method of the laundry machine of the present invention may include a spraying step (S155) for spraying the washing water through the spraying unit (6). The spraying step (S155) is a step of spraying the washing water and the detergent supplied through the supply hose and the detergent box to the drum outer back and the tub inner back through the flow guide 61 of the injection unit (6).

At this time, since the rotation of the drum disclosed in the drum rotation step (S14) continues, it is possible to remove the foreign matter on the back of the drum outside the washing water supplied from the injection portion, and also to clean the foreign matter on the inner back of the tub.

On the other hand, if the rotational speed of the drum is set to a high speed rotation in the drum rotation step (S14) it is also possible to remove the foreign matter on the drum outer peripheral surface 31 and the tub inner peripheral surface 21 together.

When the removal of the foreign matter of the drum and tub through the above-described process, it is finished through the discharge step (not shown) for discharging the washing water and detergent used for cleaning to the outside of the cabinet.

The present invention may be practiced in various forms and is not limited to the above-described embodiment. Therefore, if the modified embodiment includes the components of the claims of the present invention should be regarded as belonging to the scope of the present invention.
