Description

How to release the friction of buoyancy type washing machine

The present invention relates to a method of releasing a friction of a buoyancy type washing machine, and in particular, in a buoyant type washing machine in which a buoyancy body is washed and dehydrated while being raised and lowered by washing water supplied during washing, the buoyancy gear is the frictional force of the dewatering gear during initial washing It relates to a method of releasing the friction of the buoyancy type washing machine to be washed while being easily released from.

In general, the buoyancy type washing machine raises the buoyancy gear by the washing water supplied during washing through the buoyancy gear which is raised and lowered by the washing and draining water between the washing shaft gear and the dewatering gear to combine with the washing shaft gear. , Washing the pulsator while rotating forward and reverse, and when the drainage is completed, the buoyancy gear is lowered and separated from the washing shaft gear to be combined with the dehydrating gear to dehydrate the washing tank while rotating at high speed in one direction.

In the case of the buoyancy type washing machine which raises and lowers the buoyancy gear and washes and dehydrates it, after the washing is completed and dehydration or long time washing is not used, the buoyancy gear rises by washing water supplied during initial washing. It should be separated from the deshrink gear and combined with the laundry shaft gear. The buoyancy gear gear has a greater frictional force with the deshrink gear than the buoyancy, so it is not easily separated by the water to be washed. Since the initial washing, the strong rotational force during the initial washing to rotate the dewatering gear without rotating the washing shaft gear, the strong rotational force acts on the dewatering gear, the wear of the buoyancy gear as well as the dewatering gear. In addition to causing the motor to overload, It became a problem.

An object of the present invention is that the buoyancy gear gear which is lowered and lowered by the wash water supplied during initial washing is easily separated from the deshrink gear and combined with the washing shaft gear to wash the buoyancy gear by the rotational force during the initial washing. The purpose of the present invention is to allow washing while preventing the wear of the deshrink gear and the overload of the motor.

In order to achieve the above object, the present invention provides a washing water supplying step to the washing tank during initial washing, determining the water supply completion at a predetermined level in the step, and when the water supply is completed at the predetermined level in the step, the washing shaft gear is predetermined. And rotating the washing shaft gear at a predetermined time interval, and determining whether the washing shaft gear has been rotated a predetermined number of times, and if the washing shaft gear is completed a predetermined number of times, At the time interval of the forward and reverse rotation, washing and completing the step.

3 is a flowchart of a method for releasing frictional force of the buoyancy type washing machine of the present invention, wherein a water supply step 30 of supplying water to a predetermined level in an initial state and whether water supply is completed at a predetermined water level in the water supply step 30 is completed. If the water level judging step 31 and the water level judged in the water level judging step 31 do not complete water supply to a predetermined level, the water is supplied until the water supply is completed. Washing shaft gear forward, reverse rotation step (32), the washing shaft gear forward, reverse rotation step (32 seconds on, 0.3 seconds off) at a short time interval, forward and reverse rotation to forward and reverse rotation In the washing shaft gear rotation completion determination step 33 to determine whether the forward and reverse rotation of the washing shaft gear is completed a predetermined number (five times) and the washing shaft gear rotation completion determination step (33) Precise and reverse rotation of shaft gear When the motor is completed, the motor rotates forward and backward at a predetermined time (1.2 seconds temperature, 0.8 seconds off), and the washing step 34 performs the washing while the forward and reverse rotation of the washing shaft gear 5, and in the washing step 34. It is to be made in the laundry completion determination step 35 of washing until it is completed while judging whether the washing is in progress in the predetermined washing time.

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 for the washing operation signal input in the initialization state and proceeds to the washing while outputting the controlled signal to each drive, that is, the operation signal start signal from the operation signal input unit (a) If is input to the microcomputer (b) go to the water supply step 30 to control the water supply and drainage drive (c) to open the water supply valve to supply the washing water to the washing tank (2), but the predetermined water level (minimum water level) Watering)

Subsequently, the microcomputer (b) goes to the water level judging step 31 to determine whether the water supply is completed at a predetermined level (minimum level) of the water supply level. If the water supply is not completed at the water level, go to the water supply step 30 to continue the water supply, while on the other hand, if the water supply level is completed at a predetermined predetermined water level (minimum water level), the microcomputer (b) deshrinks the water. In order to prevent the buoyancy gear 7 coupled to the gear 6 from being easily separated without being separated by the water supplied by the frictional force, the washing shaft gear is fixed and the reverse rotation step 32 is performed. By controlling the motor driving part (e), the motor 8 is briefly rotated forward and backward at a predetermined time interval (0.3 seconds on, 0.3 seconds off), and the washing shaft gear 5 is rotated forward and reverse through the gear group 4. Let's say The microcomputer (b) goes to the washing shaft gear rotation completion determination step 33 to determine whether the forward and reverse rotation of the washing shaft gear 5 has been completed a predetermined number of times (five times), wherein the washing shaft If the forward and reverse rotation of the gear 5 has not been completed a predetermined number of times (five times), the rotation is continued. The forward and reverse rotation of the washing shaft gear 5 is completed a predetermined number of times (five times). If it is, the rotation will stop.

Thus, when the forward and reverse rotation of the laundry shaft gear 5 at a predetermined time interval (0.3 seconds temperature, 0.3 seconds off) is completed, the buoyancy gear 7 is rotated by the short time forward and reverse rotation of the laundry shaft gear 5. ) And the deshrink gear (6) is separated from the deshrink gear (6) while the buoyancy gear (7) is buoyant by the wash water supplied to a predetermined water level, so as to relax the combined friction force. As it rises to be engaged with the laundry shaft gear (5).

When the buoyancy gear 7 is fitted to the washing shaft gear 5 by the wash water supplied as above, the microcomputer (b) goes to the washing step 34 to wash the motor driving part (e). The motor 8 is rotated forward and backward at predetermined intervals (1.2 seconds on and 0.8 seconds off) to rotate the washing shaft gear 5 forward and reverse through the gear group 4. The pulsator (3) adhered to the shaft gear (5) is rotated forward and reverse to proceed with the washing.

While performing the washing while rotating the pulsator 3 forward and reverse as described above, the microcomputer (b) goes to the washing completion determination step 35 to determine whether the predetermined washing is completed, and at this time, the determination result. If the washing is not completed, the washing is continued and if the washing is completed, the next administration is performed by a predetermined program.

As described above, the present invention is a buoyancy type washing machine that performs washing and dehydration while the buoyancy gear is raised and lowered, and after the dehydration is completed, water is supplied to the washing tank at the initial washing time and the washing shaft gear is predetermined when the water supply is completed. By rotating it forward and reverse at a predetermined number of times at a short time interval and then washing and completing the buoyant gear, which is lifted and lowered by the water to be supplied, is easily separated from the dewatering gear and combined with the washing shaft gear. The frictional force provides the effect of washing while preventing the wear of the buoyancy gear or deshrink gear and the overload of the motor.
