The present invention relates to a fully automatic washing machine, and more particularly, to a fully automatic washing machine that can reduce the price of the product and prevent unnecessary waste of washing water during washing and rinsing administration by configuring the water tank and the washing tank used in the washing machine as a single unit. .

In general, the automatic washing machine has preprogrammed the washing, rinsing, drainage and dehydration strokes in the washing machine control unit in advance to allow the user to selectively control the washing operation so that the laundry can be washed automatically. It is.

Such a fully automatic washing machine is generally as shown in FIG. 1, and is installed in a water tank 2 and a water tank 2 fixedly installed inside the main body 1 of the washing machine to store a certain amount of washing water for washing. It is composed of a washing tank (3) having a 4), a power driving unit (5) which is provided at the outer lower portion of the water tank (2) to transmit power for washing.

The power driving unit 5 is provided at the outer lower portion of the water tank 2 to receive power from the driving motor 5a and the driving motor 5a to generate power to drive the washing tank 3 and the pulsator 4. It consists of a division transmission part 5b.

Accordingly, when the washing and rinsing stroke is received, the pulsator 4 is inverted by receiving the power of the driving motor 5a and repeatedly performs the washing and rinsing stroke for a pre-programmed time.

However, the following problems occur in such a general washing machine.

That is, the water tank 2 performs the function of storing the washing water required for washing during the washing administration, and the washing tank 3 installed inside the water tank 2 rotates at a high speed during the dehydration stroke, and the moisture contained in the wet laundry. To drain through a discharge hole (not shown) formed over the entire outer circumference of the washing tank (3).

Therefore, in the washing machine, two containers, namely, the water tank 2 and the washing tank 3, inevitably have to be provided, which is a factor of the price increase due to their manufacture.

In addition, since the washing water stored in the space between the water tank 2 and the washing tank 3, which is not actually washed at the time of the washing administration, is not necessarily required for the washing administration, the water stored in the space between the water tank 2 and the washing tank 3 is eventually stored. Washing water is pointed out as a result of unnecessary waste of tap water.

The present invention has been made in view of the above-mentioned conventional technical shortcomings, and consists of a single tank and a washing tank used in a washing machine, thereby reducing the product price and providing a fully automatic washing machine to prevent unnecessary waste of washing water. have.

Washing and dehydration tank 30 is formed in a single body, the power distribution unit for driving the washing and dehydration tank 30 to be described later receives the driving force of the drive motor 41 and the drive motor 41 in the lower outer portion. ) Is installed much the same as the conventional one.

In addition, the washing and dewatering tank 30 has a container shape of the upper light lower narrow side opened only on the upper side.

And the inner circumferential surface of the washing and dewatering tank 30 is provided with an upward guide means 50 for guiding the washing water dehydrated from the laundry when the washing and dehydrating tank 30 rotates at high speed.

The upward guide means 50 is integrally formed on the inner circumferential surface of the washing and dehydrating tank 30, as shown in FIG. 3 (a), and is applied to the centrifugal force of the washing and dehydrating tank 30 which rotates at a high speed during the dehydration operation described later. It has one or more valleys 51 for guiding the wash water dewatered from the laundry upwards.

The bone 51 is installed extending from the lower side to the upper end of the washing and dehydration tank 30, and it is preferable that a plurality of radially installed at equal intervals on the inner circumferential surface of the washing and dehydrating tank 30.

To this end, the inner circumferential surface of the washing and dehydration tank 30 should be configured in a polygonal shape so that a plurality of bones are formed.

The washing and dehydration tank 30 may be configured in a circular shape as shown in FIG.

However, at this time, it may be composed of a bone 51A having a semicircular shape formed repeatedly repeatedly at equal intervals over the entire rim surface of the washing and dehydrating tank (30A), it may be composed of a triangular or square shape or the like It can be changed in various ways.

In addition, although not shown separately, the washing and dehydration tank may be molded into a waveform throughout the entire surface so as to have a plurality of semicircular shapes on the inner circumferential surface.

In addition, a first drainage means 60 is provided at the upper outer side of the washing and dewatering tank 30 to primarily drain the washing water guided upward during the dehydration stroke to the lower inner side of the washing and dewatering tank 30.

The first drainage means 60 is integrally installed throughout the upper outer circumference of the washing and dehydrating tank 30, and drainage for draining the wash water overflowed to the upper side of the washing and dehydrating tank 30 during dehydration administration ( 61) has a drain pipe member 62 which is a hollow body whose one end is in communication with one of the lower end surfaces of the drainage passage 61 and the other end is in communication with the lower inner side of the washing and dewatering tank 30.

In addition, the washing water guided to the lower side of the washing and dehydration tank 30 is drained to the outside of the main body 10 by the secondary draining means.

Secondary drainage means 70 is installed in the washing and dehydration tank 30 and the pulsator 20, as shown in Figure 4 and the hollow shaft built in the power division transmission unit 42 for transmitting power to them separately ( 71) and an inflow hole 72 through which a plurality of hollow shafts 71 located between the washing and dehydrating tank 30 and the pulsator 20 are connected to each other to allow the washing water to flow into the washing and dehydrating tank 30. The main body is connected to one end of the hollow shaft 71 at one end thereof so as to be connected to the other end of the drainage guide pipe 73 and the drainage guide pipe 73 for guiding the drainage of the washing water introduced through the inlet hole 72. 10) is installed in the lower place of the inside is composed of a drain pump 74 for guiding the drainage of the wash water introduced through the drain guide pipe 73 to the outside of the main body (10).

The drain pump 74 is closed at the washing and rinsing stroke of the washing machine laid down by a microcomputer not shown to prevent the outflow of the wash water, and is opened at the draining stroke of the washing machine to open the washing, rinsing and dehydrating washing water. It is controlled to be drained out of the main body.

In addition, the inner upper side of the main body 10 is installed adjacent to the outer wall of the drainage passage 61 installed outside the upper end of the washing and dewatering tank 30 over the whole, and largely by centrifugal force during rotation of the washing and dewatering tank 30. A buffer member 80 is installed to prevent rotation.

Preferably the buffer member 80 is preferably composed of a soft cushion material.

The operation of the present invention configured as described above will be described.

That is, when washing and rinsing and rinsing, the power segment transmission unit 42, which receives the driving force of the driving motor 41, is driven and drives the washing and dehydration tank 30 and the pulsator 20 intermittently. Carry out a wash and rinse stroke.

That is, during the laundry administration, the laundry in the washing and dehydrating tank 30 performs forward and reverse rotation with the water flow generated by the intermittent rotation of the pulsator 20. At this time, the drain pump is closed to prevent the leakage of the wash water.

However, when the laundry rotates with water flow, the inner wall surface of the washing and dehydrating tank 30 is formed in a polygonal shape so that the laundry alternately moves between the inner wall surface and the bone and hits the washing plate to perform a function of rubbing the washboard. do.

Therefore, washing performance is improved.

After the washing administration is completed, the drainage administration will proceed.

At the time of drainage administration, as the drain pump 74 is opened under the control of the microcomputer, the washing water inside the washing and dewatering tank 30 is built up in the power division transmission unit 42 and is composed of the hollow shaft 71 and is washing and dewatering. After being introduced through the inlet hole 72 located between the tank 30 and the pulsator 20, it is drained out of the main body 10 through the drainage guide pipe 73 and the open drainage pump 74.

When the drainage stroke is completed, the dehydration stroke proceeds.

At the time of dehydration administration, the power division transmission unit 42 rotates the washing and dehydration tank 30 at high speed.

As the washing-and-dehydrating tank 30 rotates at high speed, water contained in the laundry inside the washing-and-dehydrating tank 30 is thrown out of the laundry by centrifugal force and then formed on the inner wall surface of the washing-and-dehydrating tank 30 inclined upward. It moves upward along the valley 51 and flows backward, and overflows into the drainage path 61 formed at the top outside of the theta and dehydration tank 30.

The overflowed wash water flows into the lower side of the washing and dewatering tank 30 through the drain pipe member 62 communicated with one of the lower end surfaces of the drainage passage 61, and then the inflow hole 72 as in the drainage stroke. The drainage pipe is drained out of the main body 10 through the drainage guide pipe 73 and the open drainage pump 74.

The present invention can perform washing and rinsing and draining and dehydrating strokes without requiring separate washing tanks required for dehydration administration and water tanks required for washing and rinsing administration.

Therefore, it consists of the water tank and the washing tank as a single unit, which reduces the product price and prevents unnecessary waste of washing water.
