In general, a laundry treatment apparatus includes: a case (cabinet) constituting an outer shape; a water tub (tub) disposed in the cabinet for holding washing water; a washing tank (or a dewatering tank) rotatably disposed in the water tub and used for holding washings.

As an example of the prior art, the laundry treatment apparatus includes: a rotatably configured pulsator; a motor (motor) for providing rotation force to the washing tank and/or the pulsator; a clutch (clutch) that operates in a manner that changes whether or not the rotational force of the motor is transmitted. Further, a clutch is known which can move up and down along a double-shaft structure of a washing shaft having an upper end coupled to a pulsator and a dehydrating shaft having an upper end coupled to a washing tub. When the clutch is lowered, the clutch is coupled to a rotor of the motor, so that a dehydrating shaft coupled to the clutch and a washing shaft coupled to the rotor can be rotated integrally. In addition, when the clutch is lifted, it is separated from the rotor, and only the washing shaft is rotated. A clutch driving device is known, which is disposed on one side of the clutch and can provide driving force to enable the clutch to operate. There is known a technique in which a driving device of a clutch is connected to one end of a lever (rod) to move the lever, and an operation connection structure is connected to the other end of the lever to convert the movement of the lever into the up-and-down movement of the clutch.

As another example of the prior art, the laundry treatment apparatus includes: a drain pipe for guiding the washing water in the water bucket to drain; and a valve operated to change whether the drain pipe is opened or closed. Valve actuating devices are known which provide the actuating force to operate the valve. The driving device of the valve is connected with one end of the moving component to enable the moving component to move, and whether the valve is opened or closed is changed through the movement of the moving component.

Fig. 2 is a plan view showing the operation of the lever 2 rotated with the driving part 400 of the component driving device 10 of fig. 1. Next, the operation mechanism of the component driving apparatus 10 will be described with reference to fig. 2.

Fig. 2 shows a state in which the lever 2 moves in the 1 st direction D1 and the 2 nd direction D2 as the driving portion 400 of the component driving device 10 rotates. In the present invention, the direction of the reciprocating motion of the structure connected to the driving portion 400 and operated by the rotation of the driving portion 400 may be defined as the 1 st direction D1 and the 2 nd direction D2. Here, a direction in which the structure is pushed open by the rotation of the active part 400 may be defined as a 1 st direction D1, and a direction in which it is pulled may be defined as a 2 nd direction D2.

The active portion 400 is disposed such that the active protrusion 430 is provided along the 1 st axial direction X1 and the cam portion (cam) 460 is provided along the 2 nd axial direction X2 with respect to the cover case 120.

The active portion 400 is rotatably disposed on the case 100. The casing 100 includes an active guide 125, and the active guide 125 contacts the active portion 400 to guide the rotation of the active portion 400. The active guide 125 extends along the periphery of the hole 120h. The active guide 125 protrudes from the cover case 120 toward the 1 st axial direction X1. This can improve the operation stability of the driving unit 400 and the plurality of gears.

The housing 100 includes a terminal cover 124 that houses a terminal 510 to be described later. The terminal cover 124 is formed with an opening portion to ensure that the corresponding structure of the terminal can be connected with the terminal 510 from the outside of the can 100.

The component driving device 10 includes a driving section 300 that provides a driving force for operating components for the laundry processing apparatus. The driving part 300 includes a motor 310 disposed in the case 100. The driving force generated by the motor 310 is transmitted to the driving part 400. In order to distinguish this motor 310 from the main motor, it may also be referred to as an auxiliary motor. In this embodiment, the motor 310 may be a direct current motor.

The case 100 is provided with a motor arrangement portion 114 in which the motor 310 is arranged. The bottom chassis 110 can house the motor 310 together with the supporting part 200. The bottom case 110 is provided with a gear arrangement space 110a in which a plurality of gears 330 are arranged.

The motor 310 provides driving force to a component (e.g., clutch or valve) for the laundry treatment apparatus. The motor 310 receives power from the power connection part 500, thereby generating driving force. The motor 310 includes a motor shaft 312 rotated by the generated driving force. The motor shaft 312 rotates about a motor rotation axis Om. In the present invention, the motor rotation axis Om is a virtual axis and does not refer to an actual component of the apparatus.

The driving part 300 includes a motor gear 320 fixed to the motor shaft 312 to rotate. The motor gear 320 rotates about a motor rotation axis Om. For example, the motor gear 320 may be a worm gear (worm gear).

The driving unit 300 includes a plurality of gears 330, and the plurality of gears 330 sequentially mesh with each other to rotate in response to the rotational force of the motor gear 320. The plurality of gears 330 include a plurality of reduction gears configured to enable the driving part 400 to rotate at a rotation speed lower than that of the motor gear 320. In the present embodiment, the start gear 331 and the 1 st to 4 th transmission gears 332, 333, 334, 335 are all reduction gears. In this case, the gear speed receiving the rotational force is lower than the gear speed transmitting the rotational force among 2 gears meshed with each other among the plurality of gears.

The plurality of gears 330 rotate about any one of the plurality of gear shafts Og1, og2, og3, respectively. The plurality of gear shafts Og1, og2, og3 may be disposed in parallel with each other.

The number of the plurality of gear shafts Og1, og2, og3 is smaller than the number of the plurality of gears 330. If a plurality of gears are arranged in a lateral direction perpendicular to the axial directions X1 and X2, the volume in the lateral direction increases, and therefore, by arranging 2 or more gears rotating about the same gear rotation axis in the axial directions X1 and X2, the lateral volume can be reduced. In the present embodiment, the 6 gears 331, 332, 333, 334, 335, 336 rotate around one of the 3 gear shafts Og1, og2, og3, respectively, but the number of the plurality of gear shafts and the number of the plurality of gears are not necessarily limited thereto.

The plurality of gear shafts Og1, og2, og3 may be arranged in parallel with the driving shaft Oa. One of the plurality of gear shafts Og1, og2, og3 may be identical to the driving shaft Oa. In the present embodiment, the gear rotational shaft Og2 may coincide with the driving rotational shaft Oa.

In the present embodiment, the start gear 331 is rotatable about the gear rotation shaft Og 1. The 1 st transmission gear 332, the 3 rd transmission gear 334, and the end gear (end gear) 336 can rotate around the gear rotation shaft Og 2. The 2 nd transmission gear 333 and the 4 th transmission gear 335 can rotate around the gear rotation shaft Og 3.

The driving part 400 receives the rotational force of the plurality of gears 330 to rotate. The driving part 400 includes a driving coupling part 420 coupled with one of the plurality of gears 330. The active coupling 420 is coupled to the end gear 336. The rotational force of the end gear 336 is transmitted to the driving part 400 through the driving coupling part 420. The driving part 400 rotates integrally with the end gear 336.

In the present invention, the term "integrally rotating" the 1 st and 2 nd components means that the 1 st and 2 nd components rotate about the same rotation axis at the same rotation speed and in the same rotation direction, and includes not only the case where the 1 st and 2 nd components are combined (or connected) to rotate together, but also the case where the 1 st and 3 rd components are combined (or connected) and the 3 rd and 2 nd components are combined (or connected) to rotate the 1 st and 2 nd components together.

The driving part 400 includes a cam part 460 rotated by the driving force of the motor 310. The outer circumferential surface of the cam portion 460 is different from the driving rotation shaft Oa in terms of the distance between the outer circumferential surface and the driving rotation shaft Oa.
