Description

Gear bite control method of buoyancy type washing machine

The present invention relates to a gear biting control method of a buoyancy type washing machine, and more particularly, in a buoyancy type washing machine which washes and dehydrates while descending by washing water supplied during washing, wherein the water is supplied by dehydration after washing or rinsing completion. The present invention relates to a gear biting control method of a buoyancy type washing machine that can be dewatered by simply engaging a buoyancy gear with dewatering with washing water.

In general, the washing machine used in our home is designed to wash or dehydrate by controlling the gear clutch of the gear unit which transmits the rotational force supplied from the motor to the pulsator and the washing tank respectively.

That is, in the case of the washing machine, the gear clutch catches the dehydration and does not operate the gear clutch during washing, so that the washing force is transmitted to the pulsator while the rotation of the washing motor is carried out. When dehydration, the gear clutch operates the gear clutch to dehydrate the shaft. By releasing the rotational force of the washing motor is transmitted to the washing tank to dehydrate.

In the case of such a washing machine, a separate driving motor and a device are additionally applied to operate the gear clutch, thereby increasing the volume and complexity of the device.

Therefore, recently, as part of the simplification of the washing machine, there is a buoyancy type washing machine using a buoyancy gear gear, which is combined with the gear of the pulsator while the buoyancy gear is raised by the washing water supplied during washing. The pulsator is washed with the forward and reverse rotation by the gear of the forward and reverse rotation, and after the washing is completed, the buoyancy gear is lowered by the wash water drained, and the gear of the pulsator is relaxed and deshrinked. When the dehydration shaft is rotated, the dehydrator is dehydrated while the washing tank is rotated.

However, in the case of the buoyancy type washing machine, there is no problem in the buoyancy gear gear coupling with the pulsator gear during washing, but the buoyancy gear gear descending due to the flow of the dewatering gear caused during washing is drained. It is not precisely matched with.

In this way, when dehydration occurs when the buoyancy gear and deshrink gear are not correctly engaged, slippage occurs between the buoyancy gear and the deshrink gear. It has a problem of wear.

An object of the present invention is a buoyancy type washing machine that proceeds washing and dehydration while lifting and lowering the buoyancy gear, and when the dehydration is completed after washing, shaking the buoyancy gear with water that is supplied by the water supply just before dehydration is easily engaged with the dehydration gear. By doing so, it is intended to prevent the wear of the gear caused by the mismatch between the buoyancy gear gear and the de-shrink gear during dehydration or normal dehydration.

In order to realize the above object, the present invention supplies water to a washing tank in an initial state, and washes while rotating the pulsator forward and reverse when water supply is completed, and drains when the washing is completed, and when the draining is completed, the water level is arbitrarily set. The buoyancy gear is flowed into the wash water to be supplied with water, and the dehydration is performed after being engaged with the dehydration gear.

Dehydration judgment to determine whether the washing completion determination step 33, the drainage step 34 to drain if the washing is completed in the washing completion determination step 33, and if the drainage is completed in the drainage step 34 Step 35 and, if dehydration in the dehydration determination step 35, rewatering step 36 for rewatering for a randomly set time, and dehydration to proceed with dehydration when rewatering is completed in the rewatering step 36 Step 37, and the detachment The dehydration completion determination step 38 to dehydrate until the dehydration is completed while judging whether or not the dehydration is completed in the water step 37.

Referring to the operation of the present invention made as described above are as follows.

First, when the laundry is put into the washing tub 2 to wash the laundry, and the driving signal for the series of washing administrations to be washed is input to the microcomputer through the driving signal input unit a, the microcomputer (b) In the washing operation signal is controlled by a predetermined predetermined program and outputs the controlled signal to each driving unit to proceed with washing, that is, the operation signal start signal is input from the operation signal input unit (a). When the microcomputer (b) goes to the water supply step 30 to control the water supply and drainage drive (c) to supply water to the water level determined according to the washing amount to open the water supply valve to start to supply the wash water to the washing tank (2) At this time, the buoyancy gear (7) engaged with the dewatering gear (6) by the wash water being supplied is raised while being buoyant by the wash water, It is meshed with the washing shaft gear (5).

In the state where the buoyancy gear 7 is engaged with the washing shaft gear 5 by the wash water supplied as above, the microcomputer (b) goes to the water supply completion judging step 31 and the water level is supplied according to the washing amount. The water level is detected by the water level detecting unit (D) to determine whether the water supply is completed at the predetermined water supply level. If the water supply is not completed, the water supply is continuously performed, and the water supply is supplied to the determined water level. When it is completed, the microcomputer (b) controls the water supply and drainage drive (c) to turn off the water supply valve, stops the water supply, and goes to the washing step 32 for washing to control the motor driving part (e) and the motor (8). ), The reverse rotation of the motor 8 causes the buoyancy gear 7 meshed with the washing shaft gear 5 to be rotated forward and reverse, and the pulsator 3 is rotated forward and reverse. The laundry will proceed.

While performing the washing while the pulsator 3 is rotated forward and reverse as described above, it is determined whether the predetermined washing is completed by going to the washing completion determination step 33, and if the washing is not completed at this time, If the washing proceeds continuously and the washing is completed, the microcomputer (b) goes to the drainage step 34 to drain the contaminated washing water and controls the water supply and drainage part (c) to proceed with the drainage. As the body gear 7 washes out of the water storage tank 1, the buoyancy gear 7 engaged with the washing shaft gear 5 is gradually separated from the washing shaft gear 5 and moved downward. Done.

As described above, if the drainage is completed while the buoyancy gear 7 moves downward, the microcomputer (b) determines whether to go to the dehydration judgment step 35 and dewatering. In the microcomputer (b), prior to dehydration, the buoyancy gear 7 is completely separated from the washing shaft gear 5 and is correctly engaged with the dehydrating gear 6, or when the dehydrating gear 6 is washed. Since it is unknown whether the state is inaccurately engaged by the flow, the microcomputer (b) goes to the resupply step 36 so that the buoyancy gear 7 is correctly engaged with the deshrink gear 6. By controlling the drainage drive unit (c), water is supplied to the washing tank 2 for a predetermined water supply time (20 seconds). The buoyancy gear (7) does not rise by shaking the buoyancy gear (7) by the hydraulic power due to the falling of the water to be supplied to the buoyancy gear (7) is meshed with the dewatering gear (6) If it is not, the shaking ensures that it is accurately engaged.

When the rewatering time is completed while the buoyancy gear 7 is engaged with the deshrink gear 6 while resupplying as described above, the microcomputer (b) goes to the dehydration step 37 and the motor driving unit (E) When the motor 8 is rotated in one direction at high speed to rotate the dewatering gear 6, the buoyancy gear 7 is also rotated in one direction at high speed, and the washing tank 2 spins at high speed. While the dehydration is being made, the microcomputer (b) goes to the dehydration completion determination step 38 to determine whether the ongoing dehydration is completed. Will be done.

As described above, the present invention is a buoyancy type washing machine that proceeds washing and dehydration while lifting and lowering the buoyancy gear, so that the dehydration gear is correctly engaged with the buoyancy gear that is lowered just before dehydration when washing is completed. By rewatering for an arbitrarily set time, the buoyant gear gear is flowed by the drop of the rewatered water so that the buoyant gear gear is correctly engaged with the dewatering gear, so that a mismatch between the buoyant gear gear and the dewatering gear when dewatering is performed It is to provide an effect that can prevent in advance the wear of the gear caused by the normal dehydration is not made.
