Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent automatic feeding device for automatically feeding a detergent into a washing tub.

2. Description of the Related Art As shown in FIG. 3, a conventional automatic laundry dispensing apparatus includes an upper frame 2 provided on an upper portion of a main body 1 of a washing machine, and an automatic laundry dispensing apparatus 3 on a rear top surface of the upper frame 2. It is arranged.

Also, the automatic detergent dispensing device 3 includes a detergent container 4.
A coil spring 6 for delivering the detergent is rotatably arranged in a detergent pushing pipe 5 provided at the bottom of the washing machine. The coil spring 6 is rotated by a motor 8 via a gear unit 7 and pushes the laundry into the laundry delivery port 9 at the end of the push-out pipe 5 and at the same time opens the side cover 11 by the solenoid 10 to drop the laundry. The dropped laundry agent passes through the substantially rectangular opening 12 of the upper frame 2 and falls onto the flowing water surface 13.
Tap water flows from the water supply valve 14 onto the running water surface 13, and the detergent and the tap water fall into the washing tub 15.

A rotating wing 15 is provided in the washing tub 15 and transmitted through a V-belt 18 by a rotating force of a large motor 17 so as to be rotatable left and right. Also, at the time of dehydration, the operation of the mechanical case 19 causes the washing tub 15
Is rotated to perform a dehydration operation. A water pan covering the outer periphery of the washing tub 15
20 are provided and receive washing water. Water receiver 20 has four corners
Hanged at 21.

Problems to be Solved by the Invention However, in the conventional configuration, there is a problem that the automatic laundry dispensing device can automatically dispose only one kind of laundry.

In other words, when a user of a washing machine uses two types of laundry detergents, for example, a normal laundry detergent and a bleach, the ordinary laundry detergent is automatically supplied by the automatic detergent dispenser, and the bleach is used. The person himself had to put it in the washing tub at the start of washing.

Therefore, an object of the present invention is to provide a laundry detergent automatic dispensing apparatus capable of automatically dispensing two types of detergents.

Means for Solving the Problems To achieve the above object, the present invention divides a laundry container case into two rooms, and at the bottom of the two rooms, pushes out the laundry inside the room to the outside of the room. Each of the two detergent extruding mechanisms is connected to one motor via a rotation transmission mechanism having a reverse wayway clutch function. The push-out mechanism is configured so that another laundry push-out mechanism operates by rotation in the reverse direction.

Operation According to the present invention, two types of detergent can be arbitrarily supplied at the beginning or during the washing process by driving and controlling the two detergent pushing mechanisms by one motor.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIG. 1, an automatic laundry dispensing device is provided at an upper portion of the main body of the washing machine, and a laundry container 4 is provided inside the automatic laundry dispensing device. The laundry container 4 is divided by a wall 22 into a first room 23 and a second room 24. A first extruded pipe 25 and a second extruded pipe 26 are provided at the bottoms of the first room 23 and the second room 24, respectively, and the inside of the first extruded pipe 25 and the second extruded pipe 26 are respectively for washing agent delivery. The first coil spring 27 and the second coil spring 28 are rotatably arranged. A first delivery port 29 and a second delivery port 30 are provided at one end of each of the first extrusion pipe 25 and the second extrusion pipe 26. A first lateral lid 33 and a second lateral lid 34, which are opened and closed by a first solenoid 31 and a second solenoid 32, respectively, are pivotally supported at the first discharge port 29 and the second discharge port 30, respectively. First outlet 29
The flowing water surface 13 is provided below the second discharge port 30.

FIG. 2 is a horizontal sectional view showing the proximity of the first extruded pipe 25 and the second extruded pipe 26. First coil spring 27
Is a left-handed spring, and the second coil spring 28 is a right-handed spring. The first coil spring 27 and the second coil spring 28 are attached to the first connection shaft 35 and the second connection shaft 36, respectively. Between the first connection shaft 35 and the first gear 37, there is provided a left clutch 38 having a left-rotating one-way clutch function for transmitting the rotation of the first gear 37 to the first connection shaft 35 only when the first gear 37 rotates left. A second gear 39 is provided between the second connection shaft 36 and the second gear 39.
Only when the gear rotates right, the rotation of the second gear 39 is
A right clutch 40 having a right-rotating one-way clutch function for transmitting the power to the vehicle is provided. The motor 8 is provided with a motor gear 41 for transmitting rotation to the first gear 37 and the second gear 39.

Here, the operation will be described. When the motor 8 rotates left, the motor gear 41 also rotates left, and the first gear 37 and the second gear 39
To the left. When the first gear 37 and the second gear 39 rotate to the left, only the left clutch 38 operates the clutch mechanism, and only the first connecting shaft 35 rotates to the left, and the second connecting shaft 36 does not rotate. With the left rotation of the first connecting shaft, the first coil spring 27 also rotates counterclockwise, and pushes the detergent in the first push-out pipe 25 to the first delivery port 29. At the same time, the first side lid 33 is opened by the first solenoid 31, and the laundry in the first room falls and is thrown in. On the other hand, when the motor 8 rotates clockwise, the motor gear 41 also rotates clockwise, transmitting the clockwise rotation to the first gear 37 and the second gear 39. When the first gear 37 and the second gear 39 rotate right,
The crack mechanism operates only on the right clutch 40, and only the second connection shaft 36 rotates rightward, and the first connection shaft 35 does not rotate. The second coil spring 28 also rotates clockwise with the right rotation of the second connection shaft, and pushes the detergent in the second push-out pipe 26 to the second delivery port 30. At the same time, the second lateral lid 34 is opened by the second solenoid 32, and the laundry in the second room falls and is thrown.

As is clear from the description of the embodiment, the laundry dispenser of the present invention divides the laundry container case into two rooms, and the laundry push-out mechanisms provided at the bottoms of the two rooms have opposite directions. The motor is connected to one motor via a one-way clutch of one type, and one direction of rotation of the motor drives one detergent, and the other direction of rotation operates in the opposite direction. Can be automatically dispensed. Therefore, it is possible to reduce the user's trouble of manually inputting a different type of detergent than the detergent supplied by the conventional automatic detergent dispenser. In addition, since two kinds of laundry agents can be automatically and arbitrarily introduced even at the beginning or in the middle of a series of washing steps, the width of the washing step can be widened and a great benefit can be provided to the user. Further, since the two laundry push-out mechanisms are controlled by one motor, the configuration can be simplified.
