How to prevent entanglement of pulsator type washing machine

The present invention relates to a method for preventing entanglement of a pulsator type washing machine, and in particular, a pulsator which prevents entanglement by simultaneously inserting at the most efficient time point during washing and rinsing by creating a poplar pattern and simultaneously performing a role of balancing water flow. It relates to a method of preventing entanglement of a food-type washing machine.

The configuration of a conventional pulsator type washing machine includes, as shown in FIG. 1, a dehydration tank (2) and a washing tank (3) capable of washing or rinsing and dehydrating laundry; A water level sensor 4 for sensing the water level of the washing tub 3; An out case (1) for accommodating the dehydration tank (2) and the washing tank (3); A water supply valve 5 for adjusting the amount of water supplied to the washing tank 3 through the water supply pipe; A pulsator 6 for mixing wash water with laundry during washing and rinsing; A motor 7 for generating power; Receiving the power of the motor (7) to rotate the pulsator (6) when washing and rinsing, and when dewatering the clutch (8) for rotating the dehydration tank (2) and washing tank (3) and pulsator (6) at the same time; ; It consists of a belt 9 which transmits the power of the motor 7 to the clutch 8.

Looking at the operation of the conventional washing machine configured as described above are as follows.

When the user puts laundry and detergent into the dehydration tank 2 and presses the start key, water is supplied to the washing tank 2 through the water supply valve 5 to a predetermined level, which is controlled by the water level sensor 4.

When water is supplied to a predetermined level, the water supply valve 5 is turned off to stop the supply of water.

Subsequently, when the motor 7 rotates clockwise and counterclockwise for a predetermined time, the belt 9 transmits the power generated while the motor 7 rotates to the clutch 8 and transmits this power. Since the received clutch 8 is washed, only the pulsator 6 is rotated.

Then, the laundry is washed by the rotational force of the pulsator (6).

Similarly, when rinsing, only the pulsator 6 is rotated, and when dehydration, the dehydration tank 2 and the washing tank 3 and the pulsator 6 are rotated at the same time to perform dehydration, and the washing, rinsing, and dehydration are sequentially performed to complete the washing. do.

Looking at the state of the water flow at the time of rotation of the pulsator 6 based on FIG. 2, when the pulsator 6 rotates, the water flow moves toward the washing tank wall by centrifugal force as shown in FIG. Climb up and fall down the center.

Since this phenomenon occurs symmetrically, the shape of the heart is also called the heart current.

However, in the conventional technique as described above, the turrets are gathered by the heart currents and entangled with each other, and the pulsator is close to the pulsator at the same speed as the pulsator as shown in FIG. Rotational force is weakened as it rotates upwards, causing entanglement by the speed difference between the upper and lower sides of the washing tank. This entanglement causes damage and requires a lot of power to take out the laundry after the laundry is finished. This leads to the dissatisfaction of housewives, the main user layer. There are problems such as acting as a cause.

Accordingly, an object of the present invention for solving the problems as described above is to provide a method for preventing entanglement of the pulsator type washing machine to reduce the entanglement phenomenon to improve the entanglement rate and vibration damping performance during dehydration.

Another object of the present invention is to provide a method of preventing entanglement of a pulsator type washing machine to prevent entanglement by properly injecting during washing and rinsing using a popping pattern for releasing tangled cloths during washing and rinsing. .

The entanglement prevention method of the present invention pulsator type washing machine for achieving the above object, by using the pulsator to make the optimum foaming pattern during washing and rinsing to insert the laundry after the start of washing and before the end of the laundry Process; A rinsing process for inserting a inflated pattern to rinse each time a rinse of a predetermined number of times after the washing is finished; When the rinse is completed a predetermined number of times, the dehydration process is completed after dehydration for a predetermined time.

As described above, the washing machine structure for performing the method consisting of several processes is the same as the conventional structure, and the operation and effect of the present invention will be described in detail as follows.

When the user puts laundry and detergent into the dehydration tank 2 and presses the start key, water is supplied to the washing tank 2 through the water supply valve 5 to a predetermined level, which is controlled by the water level sensor 4.

When water is supplied to a predetermined level, the water supply valve 5 is turned off to stop the supply of water.

Subsequently, when the motor 7 rotates clockwise and counterclockwise for a predetermined time, the belt 9 transmits the power generated while the motor 7 rotates to the clutch 8 and transmits this power. Since the received clutch 8 is washed, only the pulsator 6 is rotated.

Then, the laundry is washed by the rotational force of the pulsator (6).

When the washing starts, the laundry pattern is washed for a predetermined time, and then the laundry is washed with the poultry pattern, and the laundry is washed again with the washing pattern for a predetermined time, and the laundry is washed again with the poultry pattern.

When the rinsing cycle begins after the end of washing, one rinsing pattern is inserted in the middle of the rinsing cycle.

After the rinsing cycle is finished for the set number of times, the final washing is completed and the whole washing is finished.

When the motor is rotated once, 1, the washing pattern is rotated by 0.6 inversely by the rotational inertia of the motor. To have.

After the idle period, the motor is turned on again, and then rotated in the reverse or counterclockwise direction by 0.8. Then, the motor is turned off again to rotate the motor by the rotational inertia of the motor to have the idle period.

Eventually, the motor rotates in the forward direction of 0.8 0.6 downtime Motor rotation in the reverse of 0.8 The washing pattern is such that it has a duty equal to 0.6.

And, as shown in FIG. 4B, the pople pattern turns the motor on and off to rotate it by 0.4 in the forward or clockwise direction so that it has a rest period while rotating by 0.3 by the rotational inertia of the motor.

After the rest period, the motor is turned on again, and then rotated in the reverse or counterclockwise direction by 0.4. Then, the motor is turned off again to have a rest period while rotating by 0.3 by the rotational inertia force of the motor.

Eventually, the motor rotates in the forward direction of 0.4 0.3 rest period Motor rotation in the reverse direction of 0.4 It is a popple pattern to have a duty equal to a rest period of 0.3.

When the motor is driven with the washing pattern as described above, the water flow pattern by the pulsator 6 is the same as in FIG. 3a. When the motor is driven by the poplar pattern, the water flow pattern by the pulsator 6 is 3b. The same pattern as in FIG.

Therefore, the flow of water by the pople pattern does not generate heart flow and does not cause entanglement and performs a function of releasing the entanglement since it plays a role of spreading already entangled cloths to the outside of the washing tank 3.

In addition, popple water flows evenly spread the cloth in the washing tank (3) also plays a role of balancing water flow to prevent unbalance during dehydration.

The popple pattern thus selected should be inserted at the most efficient point in the middle of the washing process.

Because popple pattern has a shorter motor on / off cycle than washing pattern, it has a bad effect on water pumping performance related to washing performance and lint collection ability. However, it is important to select an insertion point that can provide the best performance.

As shown in FIG. 5, the above-mentioned insertion point is to insert one poplar pattern after a certain time after the start of washing in the washing process and again before the end of washing having a certain time, and once at the time of rinsing. Each time you rinse, insert one pople pattern.

When the washing process and the rinsing process with the pople pattern inserted are finished after the dehydration, the washing is done without tangling the fabric. Therefore, the increase of the entanglement rate is prevented. .

As described above, the present invention generates a pople pattern to be inserted between the washing process and the rinsing process to prevent an increase in the entanglement rate that will occur during washing and rinsing, and to form a balance water stream during rinsing dehydration. The effect is to reduce the amount.
