The present invention relates to a washing machine, and more particularly, to a washing machine capacity variable type washing machine which allows the lower part of the washing tank to be raised to facilitate the withdrawal of laundry.

1 is a block diagram of a washing machine according to the prior art.

In general, a washing machine forms an appearance and a case 104 having a cover 102 mounted on the upper side thereof so as to be opened and closed, a reservoir 106 stored in the case 104 to store wash water, and the reservoir 106. The washing tank 108 built-in to perform washing and dehydration, a drive motor 110 installed below the washing tank 108 to drive the washing tank 108 to rotate, and the reservoir 106 to the case 104. It is composed of a damper (112) for supporting the suspension and performing a buffer function.

BLDC motor is mainly used for the drive motor 110, the shaft 116 is fixed to the lower center of the washing tank 108, the rotor 120 for rotating the shaft 116, and the rotor 120 The stator 122 is disposed at a predetermined distance from the rotor 120 on the inner circumferential surface.

The shaft 116, the upper side is fixed to the lower center of the washing tank 108, the lower side is fixed to the rotor 120, the central side thereof is rotatable by the bearing 118 through the lower center of the reservoir 106 Is supported.

In addition, the stator 122 is mounted on the bottom bottom surface of the reservoir 106 in a state of being fixed to the motor housing 126.

In the conventional washing machine, the rotating magnetic field is generated by the winding coil when the power is applied to the stator 122 to rotate the shaft 116 by the interaction force with the magnetic field by the permanent magnet of the rotor 120. At this time, the washing tank 108 fixed to the shaft 116 is rotated to perform the washing action by the rotational water flow, and after washing the dehydration is performed.

However, when the washing machine according to the related art as described above takes out the laundry from the washing tank 108 after the washing and dehydration work is completed, the user must bend the waist to withdraw the laundry inside the washing tank 108. Not only is it uncomfortable, it can give a strain on the waist, while bending the waist and taking out the laundry, there is a problem that the washing machine is mainly installed due to the water on the veranda or the tub bottom which is installed, and may be injured.

The present invention has been made to solve the above problems of the prior art, an object of the present invention is to provide a laundry tub variable variable washing machine that allows the user to easily take out the laundry.

Protruding portions 18 and guide grooves 14 are formed therebetween so that the lower washing tub 16 slides up and down along the inner side of the upper washing tub 12.

As shown in FIG. 4, the drive motor 10 includes a shaft 20 having an upper end fixed to a bottom surface of the lower washing tank 12, and a rotor frame 22 integrally connected to the shaft 20. And a stator 30 installed to be spaced apart from the magnets for rotational motion 24 and the shangdong copper 28 mounted on the rotor frame 22, and the magnets 24 and 28, and the stator 30. Is installed on one side of the rotary motion stator core 34 made of a winding coil to rotate the rotary motion magnet 24 when the power is applied, and installed in the stator 30 when the power is applied to the shanghai magnet It consists of a shanghai copper stator core 38 which consists of a winding coil which moves 28 up and down.

The rotor frame 22 is formed of a pillar body 22a extending radially from the shaft 20 and a disc body 22b extending radially outward from a lower end of the pillar body 22a.

The rotary motion magnet 24 is mounted in the circumferential direction on the inner surface of the disk body 22b, the shanghai copper magnet 28 is mounted in the circumferential direction on the outer surface of the disk body 22b, The stator 30 is located between the magnets 24 and 28.

The stator 30 is fixed by a bolt 47 to an upper cover 37 fixed to the bottom surface of the water tank 4 by a bolt 51, and the lower and side surfaces of the rotor frame 22 are located on the stator 30. The lower cover 39 is fixed to the bottom surface of the reservoir (4).

Here, a sleeve bearing 42a and a radial bearing 44a are installed between the upper cover 37 and the shaft 20, and an upper portion of the pillar body 22a and the shaft 20 of the rotor frame 22 are provided. The cylindrical groove 49a is formed between the springs 48a, the upper end of which is in contact with the sleeve bearing 42a, and fits into the cylindrical groove 49a.

On the other hand, the washing tank capacity variable washing machine is as shown in Figure 5, the up / down button unit 50, 52 installed in the case 2 so that the lower washing tank 16 can be moved up and down according to the user's pressing operation And a controller 60 for applying power to the shanghai stator core 38 according to a signal applied from the up / down button unit 50.

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

First, during the washing, rinsing, or dehydration stroke, the control unit 60 supplies power to the winding coil of the stator core 34 for the rotary motion, and the magnet 24 for the rotary motion, the rotor frame 22, and the shaft. 20 is integrally rotated so that the lower washing tank 16 is rotated in the inner lower portion of the reservoir (4). At this time, the upper washing tank 12 is supported by the bearing 6 and the support 8, the projection 18 is caught in the guide groove 14 is rotated in the inner upper portion of the reservoir (4).

When the washing, rinsing, or dehydration stroke is completed, the control unit 60 cuts off the power applied to the winding coil of the stator core 34 for the rotary motion, and the magnet 24 and the rotor frame 22 for the rotary motion. The shaft 20 is stopped from rotating, and the lower washing tank 16 and the upper washing tank 12 are stopped from rotating.

When the user presses the upward button unit 50, the control unit 60 determines this, and applies power to the winding coil of the shandong copper stator core 38, and the shanghai magnet 28 and the rotor. The frame 22 and the shaft 20 are moved upward while the rotor frame compresses the spring 48a to move the lower washing tub 16 upward.

In this case, as the protrusion 18 slides along the guide groove 14, the upper washing tank 12 does not move upward, and the lower washing tank 16 moves upward through the inside of the upper washing tank 12. Moved to take out the laundry contained in the lower washing tank 16 is easy.

When the user presses the down button 52, the controller 60 determines this and cuts off the power applied to the winding coil of the stator core 38 for shanghai, and the rotor frame 22. The compressed spring 48a is relaxed to move the rotor frame 22, the shaft 20, and the stator core 38 for shandong. The rotor frame 22, the shaft 20, and the shandong copper stator core 38 are stopped after being vibrated several times between the springs 48a and 48b.

In the laundry tub variable variable washing machine of the present invention configured as described above, as the lower tub is moved upwards through the inside of the upper tub by the driving motor, the laundry is easily taken out, and the user should bend the laundry by bending the waist. There is an effect that can resolve the inconvenience.
