In general, a washing machine is a machine that removes stains on clothing. When it is put on clothing, it is removed from the fibers by the chemical action of detergent when put in the washing liquid, but it takes a long time by the action of detergent alone. Applying a mechanical action increases the speed at which the time is missing, it is the role of the washing machine to provide such a mechanical action.

1 is a right side view of a washing machine according to the prior art.

As shown in FIG. 1, the conventional washing machine includes an outer case 1 of the washing machine, a washing tub 10 suspended inside the outer case 1, and the washing tub 10 suspended from the outer case 1. At the same time it consists of four hangers (2) to perform the damper function, the pulsator (3) of the washing tank 10 and the drive unit (4) for driving the inner tank 11 of the washing tank (10).

Here, the washing tank 10 is connected to the outer tub 12 and the drive unit 4, which has four brackets 12a installed at the lower part to hang the lower side of the hanger 2, and is rotated and It consists of the inner tank 11 in which the pulsator 3 for increasing efficiency is provided.

In addition, the drive unit 4 may include a clutch device (not shown) and a planetary gear (not shown) to adjust the rotation and rotation direction of the pulsator 3 and the inner tank 11.

In addition, the upper end of the hanger 2 is hung on the bracket (1a) formed on the outer case 1, the lower end of the damper case (2b) is provided with a spring (2a) to act as a damper As described above, the bracket 12a is formed at the lower portion of the outer tub 12. Therefore, the washing tank 10 is suspended inside the outer case (1).

Referring to the operation of the washing machine according to the prior art configured as described above are as follows.

First, when a user puts laundry and detergent into the inner tank 11 and operates a washing machine, when the water rises to a predetermined height for washing by supplying water into the washing tank 10, the driving unit 4 is operated. The pulsator 3 and the inner tank 11 are rotated to wash.

After washing in the above state, when a predetermined time elapses, the driving unit 4 stops the operation, the drain valve 5 installed in the lower portion of the outer tank 12 is opened while the water in the washing tank 10 Drained to the outside through the drain pipe (6).

When the drainage is completed, the water is supplied to the washing tank 10 again to rise to a certain height to perform a rinsing operation. The rinsing operation is usually performed two to three times and is performed in the same operation as the washing operation described above. However, it takes less time to operate the drive unit 4.

When the washing and rinsing operation is completed as described above, only the inner tank 11 is rotated at a high speed so that a dehydration operation for removing water contained in the laundry is performed. That is, the inner tank 11 is rotated at a high speed so that the water contained in the laundry is moved to the outer tank 12 through a small hole formed in the inner tank 11 and then drained to the outside through the drain pipe 6. .

However, in the conventional washing machine, since the washing and rinsing operation is performed in the state in which the washing tank 10 is upright, there is a limit in washing power and a large amount of washing deviation occurs in the laundry. When collecting from 10) there is a problem that the user is difficult to take out the laundry.

The present invention has been made in order to solve the above problems of the prior art, by moving the hanger to suspend the washing tank to the outer case to incline the washing tank to facilitate the convenience of laundry storage, increase the cleaning power and reduce the washing deviation At the same time it can be expected that the dehydration washing machine is built in an upright state to provide a tiltable washing machine that can prevent the vibration and noise caused by the inclination of the washing tank.

FIG. 5 is a right side view of the washing machine according to the second embodiment of the present invention, and FIG. 5 is a graph relating to the cleaning force and the washing deviation according to the inclination angle of the washing tank, and FIG. The distribution is shown.

One embodiment of the inclined variable washing machine according to the present invention is the outer case 51 of the washing machine as shown in Figs. 2 and 3, and the washing tub 60 is installed so as to be suspended inside the outer case 51; Four hangers (52a, 52b) to suspend the washing tub 60 to the outer case 51, and the drive unit 64 is installed in the lower portion of the washing tub 60 to drive the washing tub 60 It is composed.

Here, the washing tub 60 has a pulsator 63 is installed at the lower portion and the inner tub 62 is connected to the drive unit 64 and rotated, and the hangers 52a and 52b outside the inner tub 62; It is connected to the outer casing 51 is installed so as to consist of an outer tub 61 is not rotated.

In particular, the two hangers 52a installed at the rear of the four hangers 52a and 52b have their upper parts suspended from the brackets 51a provided on the outer case 52 and the lower parts thereof with the outer tub 61. It is fitted to the formed bracket (61a), the two hangers (52b) installed in the front is fitted to the bracket (61b) of the outer tank 61 and the upper portion thereof similarly to the hanger (52a) is installed in the rear It is installed to hang on the bracket 51b installed in front of the outer case 51, the front bracket 51b is fitted by a guide 51c formed in the outer case 51 to be moved up and down. The solenoid actuator 70 operated by an electrical signal is installed below the guide 51c, and the upper part of the hanger 52b is positioned at the lower end of the guide 51c in a state where no current flows. Let 60 be tilted In the state where electric current flows, the upper part of the hanger 52b is located in the upper end part of the guide 51c, and the said washing tank 60 is made to stand upright.

That is, the state in which the washing tank 60 is inclined to the front in a state where no current flows through the solenoid actuator 70, and the washing tank 60 is upright in a state where current flows.

Referring to the operation of the tilt variable washing machine according to the present invention configured as described above are as follows.

First, when a user puts laundry into the washing tub 60 and starts washing operation, power is not supplied to the solenoid actuator 70, and the washing tub 60 is inclined. 64) is driven to wash.

In the case of the rinsing operation, the power supply is not supplied to the solenoid actuator 70 in the same manner as the washing operation described above, so that the rinsing operation is performed while the washing tank 60 is inclined.

However, in the case of dehydration, power is supplied to the solenoid actuator 70 to push up the bracket 51b fitted to the guide 51c, and thus the two front hangers 52b are pushed up to the washing tank ( 60 is upright, and in this state, the drive unit 64 is driven to rotate the inner tank 62, so that dehydration proceeds.

Then, when dehydration is completed after a certain time, the power to the solenoid actuator 70 is cut off, so that the washing tank 60 is inclined again by a predetermined angle, in which state the user of the door of the washing machine Open the laundry and take out the laundry which has been washed and dehydrated.

Of course, by using the shape memory alloy in place of the solenoid actuator 70 or by moving the bracket 51b fitted to the guide 51c using a motor to incline or upright the washing tank 60 at an angle. Can be built.

On the other hand, the second embodiment of the inclined variable washing machine according to the present invention, two hangers are installed in front of the hangers (52a, 52b) to hang the washing tank 60 to the outer case 51, as shown in FIG. The solenoid actuator 80 is provided in the lower part of 52b so that the lower part of the hanger 52b may be pushed back.

That is, the solenoid actuator 80 is supplied with power when the washing and rinsing and the washing machine door is opened to push the lower portion of the hanger 52b so that the washing tank 60 is inclined at a predetermined angle. It is not supplied so that the washing tank 60 is dehydrated in an upright position.

Of course, as in the first embodiment, the shape memory alloy or the motor may be used instead of the solenoid actuator 80 to serve as the solenoid actuator 80.

On the other hand, Figure 5 is a graph comparing the washing power and the washing deviation according to the inclination angle of the washing tank, it can be seen that the washing power and the washing deviation is respectively the maximum and minimum around 15 °. In this case, the laundry deviation is a value indicating the degree to which the washing is even.

And as shown in Figure 6 when looking at the distribution of the force at one quality point (m) of the washing tank (D) inclined at a certain angle (θ), first, gravity (mg) in the vertical direction, the inclined surface of the washing tank (D) In (S), the centrifugal force (CF) by the rotation of the pulsator or the washing tank (D) inner tank is acting respectively, the force acting on one quality point (m) of the washing tank (D) in the inclined surface (S) is the inclined surface (S In the downward direction, the force (CF + mg * sinθ), which combines the centrifugal force (CF) and the force due to gravity (mg * sinθ), acts, and the upward direction of the inclined surface (S) is the gravity force at the centrifugal force (CF). Force (CF-mg * sinθ) minus force by (mg * sinθ) will act. Therefore, the force acting on one quality point is asymmetrical compared to the washing tank standing in the vertical direction according to the inclination angle (θ) of the washing tank (D). will be.

However, if the washing tank (D) is inclined severely, since the influence of gravity (mg) is greater than the influence of the centrifugal force (CF), the imbalance of the washing tank (D) is intensified, and the difficulty of rotating driving occurs, and the washing tank ( Maternity generated along the wall of D) is weakened, and the laundry is spread evenly and the laundry is not made and is united as one. As a result, since the laundry inside the laundry is not properly washed, the washing power is reduced and the washing deviation is large. Therefore, as shown in FIG. 5, the inclination angle θ of the washing tank D is preferably inclined at 0 ° <θ <30 ° according to the washing conditions and the structure of the washing machine.

As described above, according to the present invention, the washing tank 60 is automatically tilted at the time of washing, rinsing, and opening of the washing machine door by the movement of the hanger 52b, thereby increasing the washing power and reducing the washing deviation. When dehydration, the washing tub 60 is erected in an upright state, thereby providing an effect of preventing vibration and noise that may be generated as the washing tub 60 is tilted.
