Description

[0001] Control method of washing machine [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of controlling a washing machine, and more particularly, to a method of controlling a washing machine capable of accurately detecting whether or not a bag housed in an inner bath is a razor blast or a blast.

Generally, a washing machine is an apparatus for washing clothes using an emulsifying action of a detergent, a water flow action caused by the rotation of the washing tub or the laundry blades, and a shock action applied by the laundry blades, and uses laundry detergent and water Washing, rinsing and / or dehydration so as to remove the contamination on the surface of the substrate (hereinafter referred to as a "substrate").

On the other hand, in order to carry out washing, rinsing or dewatering in an appropriate manner, it is sensed that the amount of bollers accommodated in the inner tub (hereinafter referred to as "blanching amount") is detected by the inner blanket or pulsator And the amount of the extrudate was measured indirectly based on the rotation characteristics of the extruder.

For example, when the inner tank or the pulsator is rotated in a state where the inner tank is charged with the inner tank, when the inner volume is large, the load applied to the driving unit for driving the pulsator is large. Conversely, The rotational characteristics of the driving unit will be different according to the amount of the battery, and the amount of the battery can be determined accordingly.

However, this method has a limitation in that it is impossible to judge whether the bag inserted in the inner tank is a gauze or a puffer, and accordingly, the laundry pattern is determined according to the amount of the puffer that has been put in the inner tank, , There is a problem that the driving portion is driven more strongly than necessary, thereby causing the bag to be worn.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a control method of a washing machine which can accurately detect whether a bag housed in an inner tank is a razor or a blast.

A control method of a washing machine according to the present invention is a control method of a washing machine including a casing, an outer tub hanging in the casing, an inner tub rotatably provided in the outer tub, and a pulsator rotatably installed in the inner tub, (A) detecting the amount of the pulp based on the rotational characteristics of the pulsator; (B) detecting an amount of the cloth to be attached according to a degree of deformation of the outer cloth supporting portion mounting portion on which the outer cloth supporting portion attaching the outer cloth to the casing is deformed by a load acting on the outer cloth; And (c) comparing the quantity detected in the step (a) with the quantity detected in the step (b) to determine whether the container is a sponge or a blister pack housed in the inner tank.

Alternatively, a method of controlling a washing machine according to the present invention is a method of controlling a washing machine including a casing and an outer tub suspended from the casing, the outer tub supporting portion mounting the outer tub supporting portion for hanging the outer tub to the casing, (A) detecting the amount of the debris depending on the degree of deformation by the load; (B) after the step (a), supplying wash water to the set level in the outer tank; (C) after the step (b), detecting a load amount according to a degree of deformation of the outer tub supporting part mounting part by a load acting from the outer tub; And judging whether or not the bag accommodated in the inner tank is a gauze or a blowjack based on the amount of laundry detected in the step (a), the amount of washing water in the outer tank corresponding to the set water level, and the load detected in the step (c) (D).

The control method of the washing machine of the present invention has the effect of accurately detecting whether the bag accommodated in the inner tank is a gauze or a wet cloth.

Further, the method of controlling a washing machine of the present invention has an effect of ensuring optimum washing performance by judging whether a bag housed in an inner tank is a razor or a wet suit and applying a washing pattern differently according to the result. Therefore, compared to the conventional control method in which the washing pattern is determined according to the amount of the detected cloth in the state where the cloth is put in, there is an effect that the water consumption amount and the power consumption amount can be reduced and the cloth wear resistance can be reduced.

Viscous damping which occurs when the damper cap 51 is blown up and down together with the outer tank 2 and air escapes through an air hole (not shown) of the damper cap 51 and a viscous damping which occurs when the damper cap 51 The vibration is reduced by frictional damping due to friction between the damper base 54 and the damper base 54. Here, the large amplitude or vibration of the transient state is substantially reduced by viscous damping.

The upper end of the support member 52 penetrates the pivot 55 and is exposed on the upper surface of the pivot 55. Here, the upper end of the support member 52 is coulked to prevent separation from the pivot 55, or a separate member such as a nut is used.

The deformation rate of the deformation member 40 can be detected by the deformation sensing unit 20. The deformation sensing unit 20 may be a strain gauge and the strain rate gauge may be a resistor, When deformation is applied, the deformation rate of the object to be measured is sensed using the pressure resistance effect whose resistance value changes. The deformation sensing unit 20 senses the normal strain of the deformation member 40 because the deformation sensing unit 20 is pulled in the direction in which the both ends 31 and 32 of the cutout portion of the outer- . Hereinafter, the deformation detecting unit 20 will be described as being a strain gauge.

4A to 4B, the deformable member 40 is fastened to the lower side of the supporter supporting portion 30, and fastening members 38 and 39 such as screws and bolts can be used for this purpose.

The deformation rate gauge 20 is coupled to both ends 31 and 32 of the cutout portion of the outerwear support portion mounting portion 30 by the fastening members 38 and 39 so that both ends 31 and 32 of the cutout portion of the outer- Is attached to a connecting portion (41) connecting between the first restraint end (42) and the second restraint end (43) which are respectively constrained by the connecting portion (41). The strain gauge 20 may be attached to either the upper surface or the lower surface of the connection portion 41. In this case,

The fastening hole 36 may be formed in the fastening hole 36,

5 shows a second embodiment of a structure in which a deforming member and a deformation sensing unit are installed on a supporter supporting portion to which the suspension shown in Fig. 3 is mounted. 6A, 6B, 6C and 6D show the deformable member shown in Fig.

5, in this embodiment, the deformable member 140 is fastened to the both ends 31, 32 of the cutout portion of the supporter support mounting portion 30 from the front, unlike that shown in Figs. 4A to 4B. At this time, the deformation member 140 is disposed on the outer circumferential side of the outer circumferential side (front side) of the outer tub supporting member mounting portion 30 so that the deformation member 40 is disposed at the portion where the both ends 31, 32 of the cut- As shown in Fig.

6A, 6B, 6C, and 6D, the deformable member 140 is fixed to both ends 31, 32 of the cutout portion of the outer tub support mounting portion 30 by fastening members 38, 39 such as screws or bolts The first and second restricting ends 142 and 143 are connected to each other by a first restricting end 142 and a second restricting end 142. The first restricting end 142 and the second restricting end 143 are connected to each other, 143 extending in the direction of connecting the connecting portion 141.

The strain gauge 20 is attached to the connecting portion 141 and the strain gauge 20 is attached to the connecting portion 141 in a direction connecting the first restraining end 142 and the second restraining end 143, The deformation rate of the connecting portion 141 is measured when the connecting portion 141 is pulled in the direction in which both ends 31 and 32 are extended.

6D) is rectangular, and the length of the long side (W) of the rectangle formed by the cross section and the length (T) of the short side are made to correspond to each other Experiments have shown that when the length ratio of W and T is about 4: 1, the strain rate gauge 20 determines the amount of deformation of the connecting portion 141 It was found that the strain was detected with a considerable accuracy.

The first restraining end 142 and the second restraining end 143 are respectively fastened to the fastening end 143 of the outer tub supporting portion mounting portion 30 by a fastening member such as a bolt or a nut to fasten the deforming member 140 to both ends 31, And fastening holes 142h and 143h through which the fastening members 38 and 39 are inserted. Here, the fastening holes 142h and 143h extend in a direction parallel to the long side W of the rectangular section formed by the cross section of the connecting portion 141.

The deformation rate gauge 20 is attached to the connecting portion 141 of the deformable member 140 and attached to the surfaces 141a and 141c including the rectangular long side W formed by the cross section of the connecting portion 141, The strain gauge 20 can be attached to the surfaces 141b and 142d including the short side T of the rectangle formed by the cross section of the connecting portion 141 under the same conditions. The value of the strain rate measured when attached to the surfaces 141b and 141d including the short side is attached to the surfaces 141a and 141c including the long side of the rectangle formed by the section of the connecting portion 141 I was able to find out more than poetry. Therefore, when the strain gauge 20 is attached to the surfaces 141b and 141d including the short side of the rectangle formed by the cross section of the connecting portion 141, it is possible to detect that the deforming member 140 is relatively finely deformed So that it is possible to sense the amount of stored in the inner tank 3 with higher accuracy.

The strain gauge 20 of the present embodiment shown in Fig. 5 is mounted on the front surface 141b of the supporter supporting portion 30 among the surfaces including the rectangular short side T formed by the cross section of the connecting portion 141 Respectively. Here, as shown in FIG. 7, which will be described later, of the two surfaces including the short side T of the rectangular section formed by the cross section of the connecting portion 141, the surface to which the strain gauge 20 is attached (See FIG. 6D, 141b) is formed on the opposite side of the opposed surface, so that the opposed surface of the opposed surface of the opposed surface A maximum deformation surface is defined as a surface in which the deformation rate is measured by the deformation rate gauge 20 to the greatest extent.

6A to 6D, the connecting portion 141 is formed in a rectangular parallelepiped shape having four sides connecting the first restricting end 142 and the second restricting end 143, and AA Both ends of the two side surfaces 141a and 141c including the rectangular long side W formed by the cross section of the connecting portion 141 at the incision are connected to the first and second restricting ends 142 and 143, And is gently connected. The first restricting end 142 and the second restricting end 143 are each formed with a curved surface portion 144 having a predetermined curvature 1 / R extending from the portion where the first restricting end 142 and the second restricting end 143 meet with the connecting portion 141, respectively.

Both ends of the connecting portion 141 are gently connected to the first and second restricting ends 142 and 143 so that both ends of the connecting portion 141 and the first restricting end It is possible to prevent a crack from being generated at the boundary between the first restricting end 142 and the second restricting end 143 or from being broken due to the crack.

7 is a flowchart showing an embodiment of a method of controlling a washing machine of the present invention. 8 is a flowchart showing an example of step B50 shown in FIG.

Referring to FIG. 7, the washing machine according to the embodiment of the present invention detects the laundry amount based on the rotational characteristics of the pulsator 4 and the sensed laundry amount based on the value measured by the strain rate gauge 20, It is judged whether or not the bag put in the inner tank 3 is a gauze or a puffer, taking into consideration the difference between the case where the bag is accommodated in the bag 3 and the case where the bag is put.

More specifically, in the case where the rhythm is introduced into the inner tank 3, the amount of bathed amount Zp sensed based on the rotational characteristics of the pulsator 4 and the sensed amount of water based on the value measured by the strain rate gauge 20 (Zs1) have substantially the same value.

On the other hand, when the bladder is inserted into the inner tank 3, the batch amount Zp sensed based on the rotational characteristics of the pulsator 4 is detected based on the value measured by the strain rate gauge 20, This is because a larger load is applied to the driving portion 13 due to the friction effect acting between the pulsator 4 and the entanglement of the pores in the case of the wetting.

The process of determining whether the bag inserted in the inner tank 3 is a gauze or a puffer is as follows.

The pulsator 4 rotates alternately in both directions and senses the amount of waste (A10). Here, the replenishment amount is sensed based on the rotational characteristics of the pulsator 4. For example, the conventional washing machine can detect the washing machine according to the characteristic that the speed changes differently according to the laundry amount while the rotational speed of the driving part 13 reaches the predetermined setting rpm. Alternatively, the driving part 13 rotates at a constant speed It can be detected according to the characteristic that the speed change at the time of braking depends on the amount of the braking. Alternatively, the discharge amount may be calculated according to the time required for the rotational speed of the drive unit 13 to reach the constant rpm, or the discharge amount may be calculated according to the time taken for braking the drive unit 13 rotating at a constant speed. In addition, in the technical field of the washing machine, the bulk detection using the pulsator 4 may be variously practiced by those skilled in the art.

In step A20, the amount is detected based on the measured value of the strain rate gauge 20. 1 to 6, the detailed description thereof will be omitted for the detection of the amount of debris by the strain rate gauge 20.

Thereafter, it is determined whether or not the bagged amount Zp detected in the step A10 is compared with the bagged amount Zs1 detected in the step A20, to determine whether the bagged or put in the inner tank 3 is a gauze or a blot (A30).

In step A30, if Zp is substantially larger than Zs1, it is determined that the dog put in the inner tank 3 is a dog, and the user is informed that the dog has been put in the inner tank 3 (A40). A message indicating that the user has been put in the mouth may be output in the form of sound through an output means such as a speaker or a buzzer or visually through an output means such as an LCD, an LED, a light emitting diode or the like.

On the other hand, when the difference between Zp and Zs1 is greater than or equal to a predetermined value in step A30, it is determined that the bag is accommodated in the inner tank 3 in consideration of an error occurring when the bag is detected in steps A10 and A20, . ≪ / RTI >

After step A40, the washing machine is operated by applying the laundry washing pattern (A50).

Hereinafter, a process of controlling water supply according to an embodiment of the wet laundering pattern will be described with reference to FIG.

In the washing machine according to an embodiment of the present invention, the water supply amount is set to be different according to the amount of laundry. At this time, it is preferable that the water supply amount is set according to the amount of cafes.

In steps A51 to A53, water is supplied to the settling water level in the outer tank 2 (A51). The washing machine according to an embodiment of the present invention is provided with an air chamber (not shown) so as to be in communication with the outer tub 2 and detects that the pressure in the air chamber changes as the water level in the outer tub 2 gradually increases, It is possible to judge whether or not the water level in the tank 2 has reached the set water level and to control the water level.

Here, the water supply amount required for the water level in the outer tub 2 to reach the set water level is a value known by experiment. For example, it is possible to measure the water supply amount required for the water level in the outer tank 2 to reach the predetermined water level by supplying water in a state where a predetermined amount of air is introduced into the inner tank 3. Therefore, it is preferable that the set water level is set to be low so that the bag of substantially the same volume can always be locked irrespective of the amount of the bag introduced into the inner tank 3. In a typical washing machine, the water level frequency sensed by the water level sensor is set for each section, and the water level is controlled until the target water level frequency is reached. The set water level may be set to a value corresponding to a minimum water level of each water level section at the time of supplying water corresponding to the water level frequency classified by the section.

When the water level in the outer tank 2 reaches the set water level and the water supply is stopped, as described above, since the water supply amount W required to reach the set water level already has a known value, The total amount of the washing water in the outer tub 2 is W, irrespective of whether it is a rainstorm or a blowing cloth.

After the water level in the outer tub 2 reaches the set water level and the water supply is stopped, the load is again detected by the strain rate gauge 20 (S52).

Thereafter, the difference between the load Zs2 sensed at step A52 and the water supply amount W (W, which is substantially the same as the amount of wash water in the outer tub 2 at the set water level) The amount of smoke (Zdry) is obtained by the value (A53).

Thereafter, the washing machine is operated in accordance with the laundry amount Zdry obtained in step A53 (A54). For example, washing or rinsing may be performed by supplying water to the target water level corresponding to the amount of smoke (Zdry) obtained in step A53, or the rotational speed of the inner tank (3) or the pulsator (4) may be set Washing, rinsing or dewatering can be performed.

9 is a flowchart showing another embodiment of the method for controlling the washing machine of the present invention. Referring to FIG. 9, in the present embodiment, only the strain rate gauge 20 is used to judge whether the bag inserted in the inner tank 3 is a rainstorm or a wet cloth.

First, the load is detected based on the measured value of the strain gauge 20 (B10), and water is supplied to the set water level in the outer tank 2 (B20). In a state where the water level in the outer tank 2 reaches the set water level and the water supply is stopped, the load amount is again detected by the strain rate gauge 20 (B30).

Then, based on the difference between the load Z2 sensed at step B30 and the water supply amount W required at the time of water supply up to the previously set water level, it is judged whether the bag inserted in the inner tank 3 is a gauze or a puff.

More specifically, when it is determined in step B30 that Z2-W is substantially the same as Z1, it is determined that the air is introduced into the inner tank 3 and the washer washing pattern is applied to operate the washing machine (B50) If Z2-W has a value substantially different from Z1, it is determined that the user has entered a wet cloth into the inner tank (3), the user is informed (B60), and the washing machine is operated by applying the wet laundry pattern B70).

Here, the wet laundering pattern in step B70 is a laundering pattern determined according to the amount of dry matter (Z2-W) calculated in step B40. For example, washing or rinsing may be performed by supplying water to the target water level according to the air amount Z2-W or by setting the rotational speed of the inner tank 3 or the pulsator 4 according to the air amount, Or dehydration can be performed.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and range of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
