Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an external perspective view of a washing machine of the present invention, Figure 2 is a schematic cross-sectional view showing the main portion for driving the rotation of the washing tub of the washing machine according to an embodiment of the present invention, Figure 3 is a washing machine according to an embodiment of the present invention A control block diagram for rotating the laundry introduced into the washing tank in both directions.

1 to 2, the washing machine according to the present invention has a washing tank 1 having a predetermined capacity for washing and rinsing the put laundry, and a driving force for washing the laundry put into the washing tank 1. The main body 2 configured with a bidirectional rotary motor driving unit to be described later to be provided with a smaller diameter than the widest diameter of the washing tank 1 is configured at the bottom.

The washing tank 1 is a laundry container having a predetermined storage space, and a pulsator 4a which is bidirectionally rotated to generate a washing and rinsing water stream of the laundry is formed at the inner center of the lower part thereof, and the pulsator (outside the lower part). A first rotary support member 4 coupled to 4a is constructed.

A second rotation support member 3 having a shape corresponding to the first rotation support member 4 is formed at the upper center of the main body 2 to be coupled to the first rotation support member 4.

The second rotation support member 3 of the main body 2 is coupled to the drive motor 16 (reduction gear is coupled) through the drive motor shaft 17 of the drive motor 16 driven by an external power source. The rotational driving force is transmitted to the pulsator 4a through the first rotational supporting member 4 to enable the interlocking rotation.

The main body 2 is configured with a washing and rinsing time adjusting knob 13 to enable washing and rinsing time adjustment according to a user's selection.

On the other hand, the peripheral surface of the upper second rotary support member 3 of the main body 2 forms a convex portion 5, and the peripheral surface of the bottom surface first rotary support member 4 of the washing tub 1 is a recessed portion ( 6) to correspond to the convex portion 5, when washing and rinsing a predetermined laundry is necessary, when the user naturally places the washing tank 1 on the main body 2, the concave portion 6 of the washing tank 1 By inserting the convex portion 5 of the main body 2, the lower surface of the washing tank 1 and the upper surface of the main body 2 are tightly coupled to each other, so that the second rotary support member 3 and the washing tank 1 of the main body 2 are closed. The first rotation support member 4 of the) is to be coupled.

Therefore, when driving and driving the drive motor 16 configured in the main body 2 in a state in which the washing tank 1 is coupled to the main body 2 during washing and rinsing, the second rotation in the state in which the rotational driving force is reduced by the reduction gear. The washing and rinsing are performed by passing the support member 3 and the first rotary support member 4 to the pulsator 4a to generate two-way water flow, and when the washing is not performed, the washing tank 1 is mounted on the main body 2. ) So that they can be stored separately.

Meanwhile, in FIG. 1, the lid 7, which is opened when laundry is inserted, is detachably attached to the upper part of the washing tank 1, and the pressing part 8 is formed on one side of the lid 7 to form the pressing part ( 8) the lid 7 is opened by pressing, and a plurality of outlets 9 are formed on the surface for discharging the washing water in the washing tank 1 while the lid 7 is coupled to the washing tank 1. have.

In addition, when the washing tank 1 is separated from the main body 2 by forming the engaging portion 10 at two circumferential surfaces of the washing tank 1 and engaging with the engaging portion 11 of the portable handle 12, the main body 2. ) Is stored in the washing tank (1) so that it can be moved easily. At this time, the coupling portion 10, 11 may be configured to be inserted and coupled to each other, for example, forming a protrusion and groove.

The present invention consists of a two-way water flow rotation control diagram as shown in FIG.

As illustrated in FIG. 3, the bidirectional water flow type rotary washing machine according to the present invention includes a controller 100 storing a control program for controlling the washing and rinsing operations of the washing machine as a whole.

The controller 100 stores a program for driving the motor during the washing and rinsing time set according to the operation of the time adjusting knob 13.

The bi-directional water flow type washing machine according to the present invention also includes a power supply unit 110 for supplying driving power so that the washing machine can be driven by receiving external AC power, and an operation unit 120 having the time adjustment knob 13. Under the control of the control unit 100, the bidirectional rotational driving for washing and rinsing time is performed, and the motor driving unit 130 is configured to control the driving of the bidirectional rotating driving motor 16 to generate the bidirectional water flow for washing and rinsing. .

The bi-directional water flow type washing machine according to the present invention also includes a timer 150 that provides time information so that the control unit 100 can determine the washing and rinsing time set by the user through the time adjusting knob 13 of the operation unit 120. ) Is configured.

Washing and rinsing operations of the washing machine of the present invention configured as described above will be described in detail with reference to FIGS. 1 to 3.

First, the washing machine driving power is supplied through the power supply unit 110 (this is done before the laundry is added or after the laundry is the user's option) is a predetermined amount of laundry in the washing tank (1) for washing When the user inputs, the user adjusts the washing time through the time adjusting knob 13 of the operation unit 120.

Accordingly, the control unit 100 outputs a control signal for driving the bidirectional rotation driving motor to the motor driving unit 130 according to the set washing time.

Therefore, the motor driving unit 130 receives the control signal of the control unit 100 and drives the driving motor 16 in both directions in accordance with the set washing time.

When the motor 16 rotates in both directions, the second rotation support member 3 connected to the motor shaft 17 is interlocked and rotated in a state where the rotation speed thereof is reduced by the reduction gear, thereby rotating the first rotation support member 4. The pulsator (4a) coupled through the rotation also generates two-way water flow to wash the laundry in the washing tank (1).

In this state in which washing is performed, the controller 100 checks the time information input from the timer 150. As a result of the check, when the washing time set by the user has elapsed, the bidirectional rotation driving motor is transmitted to the motor driving unit 130. Outputs a drive stop control signal to stop the rotation drive of the bidirectional rotation drive motor 16.

Accordingly, the user completely separates the lid 7 from the washing tub 1 for convenience, opens the upper portion of the washing tub 1, lifts it from the main body 2, and discards the washing water, or the lid 7 includes the washing tub ( Lifting the washing tank 1 from the main body 2 in the state coupled to 1) discards the washing water through the outlet (9).

Thereafter, the user performs a rinse on the laundry in which the washing is completed, in the same manner as the washing operation described above. Therefore, detailed description is omitted.

As described above, according to the compact washing machine of the present invention, washing and rinsing a small amount of laundry by using a bidirectional water flow generated by a bidirectional rotating motor has an effect of improving washing efficiency.
