Advantages and features of the present invention, and methods of achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various forms, and only the embodiments of the present invention make the disclosure of the present invention complete, and those of ordinary skill in the art to which the present invention pertains. It is provided to fully inform the person having the scope of the invention, the invention is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

1 is a cross-sectional view schematically showing the configuration of a washing machine according to an embodiment of the present invention. 2 is a block diagram showing a control relationship between main components of a washing machine according to an embodiment of the present invention.

1 to 2, the washing machine according to an embodiment of the present invention is the main body or casing (1) forming the appearance of the washing machine, the outer tank (2) provided in the casing (1) containing the wash water, An inner tank 3 rotatably provided in the outer tank 2 and a cloth is introduced therein, a pulsator 4 rotatably provided at the bottom of the inner tank 3, and an inner tank 3 and / or a pulsator ( 4, a drive unit 13 for driving 4, a water supply unit 12 for supplying wash water into the outer tank 2 and the inner tank 3, a drain 14 for draining the wash water from the outer tank 2, It includes an outer tub support that suspends the outer tub 2 in the casing 1. The control unit 11 controls the overall operation of the washing machine, calculates the amount of water contained in the inner tank 3 according to the strain measured by the strain gauge 20, and washes the water supplied by the water supply unit 12 based on this. The amount of water, the driving pattern of the driving unit 13 and the operating time of the draining unit 14 can be controlled.

The outer tub support is sufficient if one end is connected to the outer tub 2 and the other end is connected to the casing 1 to support the outer tub 2 to be suspended in the casing 1. It does not have to be configured as a device. For example, in the case of a washing machine which is generally called a drum washing machine and is provided with a horizontally open outer tub 2 so that a cloth can be fed from the front, damping means for cushioning vibration of the outer tub 2 separately from the outer tub support. It may be provided.

Therefore, the outer shell support is described below as a suspension device 50 or suspension, but this is only an example of the outer shell support, and as described above, the outer shell support means that the outer shell 2 can be suspended in the casing 1. It should be interpreted that the absence is present.

Suspension device 50 is one end is connected to the casing 1 by the outer shell support portion mounting portion 30, the other end is connected to the lower outer peripheral surface of the outer tub (2). The suspension device 50 absorbs vibration generated when the inner tank 3 and / or the pulsator 4 rotates by the driving unit 13, and a more detailed configuration of the suspension device 50 will be described later.

3 is a cross-sectional view illustrating a suspension device of a washing machine according to an embodiment of the present invention. Referring to FIG. 3, the suspension device 50 is installed on the lower outer periphery of the outer tub 2 and is provided with a damper cap 51 interlocked with the outer tub 2, and an outer tub support mounting portion 30 fixed inside the casing 1. Pivot 55 to be mounted on the support member 52, one end penetrates the damper cap 51 and the other end is coupled to the pivot 55, and the damper cap 51 is installed inside the outer tub 2. A damper spring (53) for absorbing vibration and a damper base (54) installed in the lower opening of the damper cap (51) to support the support member (52) or the damper spring (53).

When the damper cap 51 vibrates up and down together with the outer tub 2, viscous damping occurs when air escapes through an air hole (not shown) of the damper cap 51, and the damper cap 51 Vibration is reduced by frictional damping caused by friction between the damper base 54 and the damper base 54. Here, large amplitudes or vibrations in the transient state are reduced by almost viscous damping.

The upper end of the support member 52 penetrates the pivot 55 and is exposed to the upper surface of the pivot 55. Here, the upper end of the support member 52 is caulked (coulking) to prevent separation from the pivot (55) or uses a separate member such as a nut.

The outer shell support portion mounting portion 30 may be formed integrally with the casing 1, but as described below, the outer support portion mounting portion 30 may be formed separately from the casing 1 and fixed to the inside of the casing 1. Preferably, the outer shell support mounting portion 30 is disposed at four corners of the casing 1.

FIG. 4A is a view of a first embodiment of a structure in which a deformation member and a deformation sensing unit are installed in an outer tub support mounting unit in which the suspension device shown in FIG. 3 is mounted, and the outer tub support mounting unit is viewed from above. Figure 4b shows a view of the coupling state of the suspension and the deformable member according to Figure 4a viewed from the bottom side.

4a to 4b, the outer support portion mounting portion 30 is formed with a mounting hole (30h) so that the support member 52 can penetrate, a portion of the mounting hole (30h) is cut, the mounting hole (30h) Deformation members 40 are installed at both ends 31 and 32 of the incision. According to the magnitude of the load applied from the outer tub 2 through the support member 52, the degree of opening of both ends 31 and 32 of the cutout hole 30h is different, and by the two ends 31 and 32 of the cutout. The degree of deformation of the deforming member 40 to be constrained will vary.

The washing machine of the present invention detects a quantity of water by measuring a strain of the deformation member 40 that is deformed by a tensile force generated as the both ends 31 and 32 of the cutout portion of the mounting hole 30h are opened according to the quantity of water. do.

The strain of the deformation member 40 may be detected by the strain sensing unit 20. The strain sensing unit 20 may include a strain gauge, and the strain gauge may be a resistor such as a metal or a semiconductor. When the deformation is applied, the deformation rate of the object to be measured is detected by using a pressure resistance effect in which the resistance value changes. Since the deformation member 40 is tensioned in the direction in which both ends 31 and 32 of the cutout portion of the outer shell support part mounting portion 30 are opened, the deformation detection unit 20 detects a normal strain of the deformation member 40. It is preferable. Hereinafter, the deformation detection unit 20 will be described as being a strain gauge.

As shown in Figures 4a to 4b, the deformable member 40 is fastened to the lower side of the outer shell support mounting portion 30, for this purpose fastening members 38, 39, such as screws or bolts can be used.

The strain gauges 20 are coupled to both ends 31 and 32 of the cutout mounting portion 30 by the fastening members 38 and 39, and both ends 31 and 32 of the cutout portions of the outer shell support mounting portion 30. It is attached to the connecting portion 41 which connects between the first restraining end 42 and the second restraining end 43 respectively constrained by, to measure the longitudinal strain of the connecting portion 41. The top surface and the bottom surface of the connection portion 41 will be deformed to substantially the same degree, the strain gauge 20 may be attached to either the top surface or the bottom surface of the connection portion 41.

In order to have sufficient rigidity with respect to the load transmitted by the support member 52, a rib 33 structure is formed on the upper surface of the outer shell support mounting portion 30, and when the wash water is scattered in the space surrounded by the rib 33 A drain hole 34 for draining it may be formed. In addition, a plurality of ribs 37 for rigid reinforcement extending radially from the mounting hole 30h may be formed on the bottom surface of the outer shell support mounting portion 30, and screws or bolts may be formed around the outer shell support mounting portion 30. A fastening hole 36 through which the fastening means may be formed, and the fastening means penetrates the fastening hole 36 and is fastened with the casing 1.

FIG. 5 illustrates a second embodiment of a structure in which a deformation member and a deformation detection unit are installed in the outer shell support unit mounting unit on which the suspension device shown in FIG. 3 is mounted. 6A, 6B, 6C and 6D show the deforming member shown in FIG.

Referring to FIG. 5, in the present embodiment, the deformable member 140 is fastened from the front to both ends 31 and 32 of the cutouts of the outer shell support mount 30, unlike those shown in FIGS. 4A to 4B. At this time, the deformable member 140 is the front outer circumferential side of the outer shell support mounting portion 30 so that the deforming member 40 is disposed at the portion where the cutout ends 31 and 32 of the outer shell support mounting portion 30 have the greatest extent. It is preferable to be mounted on.

6A, 6B, 6C, and 6D, the deforming member 140 is fixed to both ends 31 and 32 of the cutout portions of the outer shell support mounting portion 30 by fastening members 38 and 39, such as screws and bolts, respectively. The first restraint end 142 and the second restraint end 143 and the first restraint end 142 and the second restraint end 143 are connected to each other. 143 includes a connecting portion 141 formed long in the connecting direction.

The strain gauge 20 is attached to the connecting portion 141, and the strain gauge 20 is connected between the first restraint end 142 and the second restraint end 143, that is, the cutout portion of the outer shell support mounting part 30. The strain when the connecting portion 141 is stretched in the direction in which both ends 31 and 32 are opened is measured.

On the other hand, the connecting portion 141 has a rectangular cross section (see FIG. 6D) when cut along AA in FIG. 6A, and is formed according to a ratio of the length (W) of the long side and the length (T) of the rectangle formed by the cross section. Strain will vary, and experiments show that when the ratio of length W to T is approximately 4: 1, within a predetermined amount of allowable range in the inner tank 3, the strain gauge 20 is connected to the connection portion 141. It was found that strain was detected with significant accuracy.

In order to fasten the deforming member 140 to both ends 31 and 32 of the cutout portion of the outer shell support mounting portion 30, a fastening member such as a bolt or a nut is attached to the first restraint end 142 and the second restraint end 143, respectively. Fastening holes 142h and 143h through which 38 and 39 penetrate are formed. Here, the fastening holes 142h and 143h extend in a direction parallel to the rectangular long side W formed by the cross section of the connecting portion 141.

The strain gauge 20 is attached to the connecting portion 141 of the deformation member 140, and is attached to the surfaces 141a and 141c including a rectangular long side W formed by the cross section of the connecting portion 141, or the connecting portion 141. It may be attached to the surface (141b, 142d) including the rectangular short side (T) formed by the cross section of the cross section of the cross section, and according to the experiment, the strain gauge 20 of the rectangle formed by the cross section of the connecting portion 141 under the same conditions The value of the strain measured when attached to the surfaces 141b and 141d including the short sides is to be attached to the surfaces 141a and 141c including the rectangular long sides of the cross section of the connection portion 141. It was greater than the hour. Therefore, when the strain gauge 20 is attached to the surfaces 141b and 141d including the rectangular short sides formed by the cross section of the connecting portion 141, the strain member 140 may detect even the relatively fine deformation. It is possible to detect the quantity contained in the inner tank 3 with higher accuracy.

On the other hand, the strain gauge 20 of the present embodiment shown in FIG. 5 is in the front surface 141b of the outer shell support mounting portion 30 among the surface including the rectangular short side (T) formed by the cross section of the connecting portion 141. Attached. Here, the surface (see FIG. 6D, 141d), to which the strain gauge 20 is attached, as shown in FIG. 7 to be described later among two surfaces including a rectangular short side T formed by the cross section of the connecting portion 141. The supporting part mounting portion 30 is defined as an opposing surface, and the surface on which the strain gauge 20 is attached (see FIG. 6D and 141b) is formed opposite to the opposing surface, as shown in FIG. 5. The deformation is relatively larger than that of the plane, which is the plane at which the strain is measured by the strain gauge 20 to the maximum.

6A to 6D, the connecting portion 141 is formed in a rectangular parallelepiped shape having four sides connecting the first restraining end 142 and the second restraining end 143. Accordingly, 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 time of cutting may have a first curvature end 142 and a second constraint end 143 and a predetermined curvature. It forms a gentle connection. To this end, the first constrained end 142 and the second constrained end 143 are each formed with a curved portion 144 extending with a predetermined curvature 1 / R from a portion that meets the connecting portion 141.

Both ends of the connecting part 141 are gently connected to the first restraining end 142 and the second restraining end 143, respectively, so that when the connecting part 141 is tensioned, both ends of the connecting part 141 and the first restraining end ( 142 or the crack is generated at the boundary between the second restraint end 143 or there is an effect that can be prevented from occurring.

7 is a flowchart illustrating an embodiment of a control method of a washing machine of the present invention. FIG. 8 is a flowchart illustrating an example of step B50 illustrated in FIG. 7.

Referring to FIG. 7, a washing machine according to an embodiment of the present invention includes a quantity detected based on a rotation characteristic of a pulsator 4 and a quantity detected based on a value measured by a strain gauge 20. Focusing on the difference between the case in which the raisins are accommodated in the case (3) and the case in which the wet foam is introduced, it is determined whether the fabric injected into the inner tank 3 is the raisins or the wet foam.

In more detail, when the raisins are put into the inner tank 3, the quantity of detected Zp based on the rotation characteristic of the pulsator 4 and the amount of detected quantity based on the value measured by the strain gauge 20 (Zs1) has substantially the same value.

On the other hand, when a wet bubble is introduced into the inner tank 3, the amount of storage Zp detected based on the rotational characteristics of the pulsator 4 is detected based on the value measured by the strain gauge 20. It has a larger value than), because in the case of the wet cloth, a greater load is applied to the drive unit 13 due to the frictional action acting between the pulsator 4 or the entanglement of the follicles.

The process of judging whether the fabric injected into the inner tank 3 is a raisin or a wet foam is as follows.

The pulsator 4 alternately rotates in both directions to detect the amount of air (A10). Here, the quantity is detected based on the rotational characteristics of the pulsator 4. For example, the conventional washing machine may detect the driving unit 13 while the rotational speed reaches a predetermined set rpm according to a characteristic in which the speed varies according to the quantity of water, and the driving unit 13 rotates at a constant speed. The speed change at the time of braking can be detected according to the characteristics depending on the quantity of the gun. Alternatively, it is also possible to calculate the amount of dose according to the time taken for the rotational speed of the drive unit 13 to reach a certain rpm, or to calculate the amount of dose according to the time taken to brake the drive unit 13 rotating at a constant speed. In addition, the quantity detection using the pulsator (4) in the technical field of the washing machine may be variously performed by those skilled in the art.

In step A20, the amount of light is sensed based on the measured value of the strain gauge 20. The sensing of the amount of capacity by the strain gauge 20 is omitted as described above with reference to FIGS. 1 to 6.

Thereafter, by comparing the detected amount Zp in step A10 and the detected amount Zs1 in step A20, it is determined whether the cloth injected into the inner tank 3 is a raisin or a wet bubble (A30).

In step A30, when Zp is substantially larger than Zs1, it is determined that the bubble injected into the inner tank 3 is a wet bubble, and the user is notified that the bubble is injected into the inner tank 3 (A40). The message informing that the foam is input may be output in the form of sound through an output means such as a speaker or a buzzer, or may be visually displayed through output means such as an LCD, an LED, a light emitting diode, and the like.

On the other hand, taking into account the errors occurring during the detection of the amount of the step in steps A10 and A20, in step A30, when the difference between Zp and Zs1 is more than a predetermined value, it is determined that the bag accommodated in the inner tank (3) is a wet pack, otherwise It can be judged that

After step A40, the washing machine operates by applying a wet laundry pattern (A50).

Here, the process of controlling the water supply according to one embodiment of the wet cloth washing pattern will be described with reference to FIG. 8.

In the washing machine according to an embodiment of the present invention, a water supply amount is set differently according to a quantity of water. At this time, it is preferable that the water supply amount is set according to the amount of currants.

Steps A51 to A53 is a process of obtaining the amount of dried raisins in which the amount of water contained in the cloth is excluded. First, water is supplied to the set water level in the outer tank 2 (A51). Washing machine according to an embodiment of the present invention is provided with an air chamber (not shown) to communicate with the outer tank 2, by detecting the change in the pressure in the air chamber as the water level in the outer tank 2, the outer tank It is possible to determine whether the water level in (2) has reached the set water level and to control the water supply.

Here, the water supply amount required for the water level in the outer tank 2 to reach the set water level is a value known by experiment. For example, the water supply in the state in which a predetermined amount of raisins is put into the inner tank 3 can be measured to measure the amount of water required for the water level in the outer tank 2 to reach the set level. Therefore, it is preferable that the set water level is set low so that the cloth of substantially the same volume can be locked at all times regardless of the amount of the cloth put into the inner tank 3. In a typical washing machine, the water level frequency detected by the water level sensor is set for each section, and the water supply is controlled until the target water level frequency is reached. The set water level may be set to a value corresponding to the minimum water level in each water level section when water supply is made corresponding to the water level frequency divided by the sections.

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 is a known value, the carriage fed into the inner tank 2 is introduced. The total amount of wash water in the outer tub 2 is W regardless of whether it is a dry or a dry cloth.

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

Thereafter, the difference between the load amount Zs2 sensed in step A52 and the water supply amount W required for water supply up to the already known set water level (which is substantially the same as the amount of wash water in the outer tank 2 at the set water level). The dry amount Zdry is calculated | required by the value (A53).

Subsequently, the washing machine is operated by applying a washing pattern according to the dry amount (Zdry) obtained in step A53 (A54). For example, washing or rinsing by supplying water to the target water level corresponding to the dry amount Zdry obtained in step A53, or setting the rotation speed of the inner tank 3 or the pulsator 4 according to the dry amount Washing, rinsing or dehydration can be performed.

9 is a flowchart illustrating another embodiment of a control method of a washing machine of the present invention. Referring to FIG. 9, in the present embodiment, only the strain gauge 20 is used to determine whether the fabric injected into the inner tank 3 is a dry or wet fabric.

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

Subsequently, it is determined whether the bag is placed in the inner tank 3 is dry or wet based on the difference between the load amount Z2 sensed in step B30 and the water supply amount W required for water supply up to the predetermined level.

More specifically, when it is determined that Z2-W is substantially the same as Z1 in step B30, it is determined that the raisins are put into the inner tank 3, and the washing machine is operated by applying a dry cleaning pattern (B50), on the contrary, step B30. If Z2-W has a substantially different value from Z1, it is determined that a wet bubble is put into the inner tank 3, and the user is notified of this (B60), and the washing machine is operated by applying a wet washing pattern ( B70).

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

Those skilled in the art will appreciate that the present invention can be embodied in other specific forms without changing the technical spirit or essential features of the present invention. 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 indicated by the scope of the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalent concept are included in the scope of the present invention.
