Abstract

A washing machine capable of preventing a magnet, which detects a number of rotations of a washing shaft, from being removed from a predetermined position. The washing machine includes a drive motor to generate a rotating force. A washing shaft is rotated by the drive motor. A belt and a shaft pulley transmit the rotating force from the drive motor to the washing shaft. A magnet is mounted to the shaft pulley to rotate along with the shaft pulley. A magnetic sensor detects a number of rotations of the washing shaft, in response to a change in a magnetic field produced by the magnet. A locking unit is mounted at a first end thereof to the magnet, and at a second end thereof to the shaft pulley. Therefore, even when the vibrations caused by operations of the washing machine are transmitted to the magnet for a lengthy period of time, the magnet is connected to the shaft pulley by the locking unit without being removed from a predetermined position.

Magnet 61 is installed on the shaft pulley 21a, and the formation annular shape is passed magnet 61 and is installed to shaft pulley 21 to allow first washing shaft 21.In addition, magnet 61 is set to its north and south poles alternately along the circumferential directions of magnet 61.Therefore, when magnet 61 rotations, the magnetic field of being detected by magnetic sensor 62 changes.
In order to utilize lock cell 63 that magnet 61 is installed on the shaft pulley 21a, a plurality of through hole 21b are set on the shaft pulley 21a, so that extend axially by shaft pulley 21a.In addition, lock cell 63 comprises first and second lock part 63a and the 63b.The first lock part 63a is outstanding so that supported by magnet 61 from the external peripheral surface of first end of lock cell 63, and the second lock part 63b is arranged on second end of lock cell 63 so that extend towards the center of lock cell 63.Second lock part 63b strain when passing through hole 21b, and after passing through hole 21b, flexibly recover its original form so that supported by edge around through hole 21b.Magnet 61 comprises the arrangement depression 61a that is positioned on its inner periphery, thereby the first lock part 63a of lock cell 63 is arranged in the corresponding arrangement depression 61a of magnet 61.
Magnetic sensor 62 is installed to the predetermined portions of lower house 27b with downward extension, the changes of magnetic field that the excircle of an end in contact magnet 61 of magnetic sensor 62 causes with the rotation that detects magnet 61.According to this embodiment, the Hall element that utilizes Hall effect is as magnetic sensor 62.
Operation and operating effect according to washing machine of the present invention below will be described.
When carrying out laundry operations, the draining valve 15b that is arranged on the pre-position below the water drum 11 is closed.In addition, owing to the trip(ping) lever 30 with brake lever 29 joint operations rotates along certain direction, the wind spring 28a that then is enclosed on the supporting pin 28 remains on rotation status, so brake band 25 is tightened up the rotation with restriction brake drum 24.At this moment, the sleeve 54 loosen the clutch springs 53 that rotated by trip(ping) lever 30, thus there be not transmission of power between spin-dry axle 23b and the transfer member 51 down.
Under such state, when first washing shaft 21 is driven motor 17 rotations, be arranged on planetary gear 42 rotation when the central gear 41 with first washing shaft 21 meshes in the brake drum 24.At this moment, because the internal gear 43 that is arranged on brake drum 24 inner surfaces is fixed, therefore a plurality of planetary gears 42 are around central gear 41 revolutions, and the central shaft around self rotates simultaneously.When a plurality of planetary gears 42 turn round around central gear 41, support 44 rotations.Like this, 22 rotations of second washing shaft, its rotating speed is reduced simultaneously.Because the pulsator 16 that is arranged in the rotating cylinder 12 is connected to second washing shaft 22, thus pulsator 16 with low speed rotation with the clothing in the agitator treating water.Like this, only first and second washing shaft 21 and 22 rotations, thus rotating cylinder 12 stops pulsator 16 rotation the time, to carry out laundry operations.
After finishing laundry operations, carry out the rinsing operation.In rinsing operating period, supply water operation and drain operation are performed several times.After the rinsing operation is finished, carry out the spin-dry operation.In order to carry out drain operation, draining valve 15b is opened by the drain motor (not shown).At this moment, be pulled with the brake lever 29 and the trip(ping) lever 30 of drain motor (not shown) joint operation, thereby brake band 25 is loosened, thus the braking of brake off drum 24.In addition, sleeve 54 is released by the rotation of trip(ping) lever 30.Therefore, sleeve 54 is by the rotation of the elastic force of clutch spring 53, recovering its original state, thus the outer surface of clutch spring 53 tensioning transfer members 51.Transfer member 51 is along with the rotation of first washing shaft 21, and is connected to down spin-dry axle 23b by clutch spring 53.
When drive motors 17 rotated with such state, following spin-dry axle 23b was with 21 rotations of first washing shaft.Like this, upper and lower spin-dry axle 23a and 23b and first and second washing shaft 21 and 22 are rotated simultaneously, thereby cause that pulsator 16 and rotating cylinder 12 rotate simultaneously, thereby carry out the spin-dry operation.Like this, central gear 41 rotates with identical speed with brake drum 24, thereby planetary gear 42 stops the rotation around self central axis simultaneously around central gear 41 revolutions.Like this, second washing shaft 22 is rotated with speed mutually with last spin-dry axle 23a.
After finishing spin-dry, trip(ping) lever 30 is discharged by the operation of drain motor (not shown).At this moment, brake band 25 is by the tensioning of the rotation of trip(ping) lever 30 institute, thereby acts on brake drum 24.In addition, clutch spring 53 is released, thereby anti-stopping power is sent to down spin-dry axle 23b.
According to the present invention, although because when the operation of washing machine makes revolving force be sent to first washing shaft 21 from drive motors 17, vibration repeatedly is sent to magnet 61, yet the first lock part 63a of lock cell 63 is installed among the arrangement depression 61a of magnet 61, and the second lock part 63b of lock cell 63 passes through hole 21b and supported by the edge around through hole 21b.Therefore, magnet 61 is installed on the shaft pulley 21a and can remove from the precalculated position.
From above description, clearly the invention provides a kind of washing machine, its magnet that structurally utilizes lock cell to be used in the revolution that detects washing shaft is installed on the shaft pulley, be removed from preposition so that prevent magnet, even the vibration that causes in the operation of washing machine also is like this when being passed to long time of magnet.
Although this illustrate and described some embodiment of the present invention, but those skilled in the art will appreciate that, can change these embodiment under the situation that does not depart from principle of the present invention and essence, its scope is limited in the scope of claim and equivalent thereof.
