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

3 is a side sectional view showing a washing machine according to the present invention, Figure 4 is a perspective view of the tub cover of the washing machine according to the present invention.                     

The washing machine according to the present invention is installed to hang inside the case 52 as shown in FIG. 3 and is rotatably installed in the outer tub 54 and the outer tub 54 in which washing water is contained therein and with laundry. Washing tank 56 consisting of an inner tank 55 formed with a plurality of dehydration holes (55a) so that the wash water is contained, and a pulsator is rotatably installed on the bottom surface of the inner tank 55 to form a rotating water flow in the washing tank 56 And a clutch 60 installed below the outer tub 54 to connect the inner tub 55 or the pulsator 58 to selectively drive the inner tub 55 or the pulsator 58; It is installed on the upper end of the motor 62 and the outer tub 54 and guides the washing water rising along the inner wall surface of the outer tub 54 by centrifugal force when the inner tub 55 is rotated. Natural by storing some overflowing wash water It is configured to include a tub cover 70 such that foot.

Of course, in the case 52 of the upper side of the washing tank 56, a detergent box housing 66 having a flow path formed therein is connected to the water supply valve assembly 64 for supplying the washing water to the washing tank 56 side. The detergent box housing 66 is detachably mounted to the detergent box 68 in which detergent is stored.

Here, the inner tub 55 is rotatably installed at a predetermined interval inside the outer tub 54, the tub cover 70 is a ring shape so that the outer circumference is screwed to the upper end of the outer tub 54. Is installed.

In particular, the tub cover 70 is a storage groove for storing the washing water is naturally evaporated when the washing tank overflows as the inner tank 55 is rotated as shown in FIG. 72 is formed in a ring shape on the outer circumferential side of the tub cover 70, and a water level sensor (not shown) installed at one side of the water supply valve (not shown) included in the water supply valve assembly 64 or the outer tub 54. When the wash water continues to be supplied due to a failure of the water, etc., and a relatively large amount of wash water overflows, a drainage hole 74 for discharging the wash water immediately is formed by cutting a portion of the storage groove 72.

In this case, a pair of ribs 76a and 76b are formed between the storage groove 72 and the drainage hole 74 so that a predetermined amount of washing water may be stored in the storage groove 72. 76a and 76b are formed in predetermined height.

In addition, the tub cover 70 has a portion (A) in which the drain hole is formed to be lower than the portion (B) in which the water storage groove is formed so as to guide the washing water to overflow, and the drain cover A pair of guide ribs 78a and 78b for guiding the flow is formed between the hole A and the water storage groove B.

Usually, the wash water is supplied through the detergent box housing 66 and the detergent box 68 to the upper side of the washing tank 56 by the water supply valve assembly 64 so that the wash water can be immediately drained when it overflows. The tub cover 70 is fixed to the upper end of the outer tub 54 such that the drain hole 74 is located below the detergent box 68.

Looking at the operation of the present invention configured as described above are as follows.

First, when the washing machine is operated in a state in which laundry is contained in the inner tank 55, the water supply valve is activated to open a flow path by detecting a quantity of water, and the washing water is disposed in the detergent box housing 66 and the detergent box 68. The water is supplied to the washing tank 56 to a certain level, and then the water supply valve is operated to block the flow path.

Next, when the wash water is supplied into the washing tank 56, the inner tank 55 or the pulsator 58 is selectively rotated and the washing and rinsing strokes are repeatedly performed.

At this time, since the inner tub 55 is installed and rotated at a predetermined interval inside the outer tub 54, the wash water between the outer tub 54 and the inner tub 55 is along the inner wall surface of the outer tub 54. Ascending and hitting the rear surface of the tub cover 70, it is sprayed again to the upper side of the inner tank 55 to improve the cleaning and rinsing performance.

Of course, the washing water is scattered as the inner tank 55 is rotated. Since the amount of the washing water being scattered is relatively small, the washing water overflowed to the upper surface of the tub cover 70 is stored in the water storage groove 72. It will build up and naturally evaporate over time.

On the other hand, when the wash water continues to be supplied into the washing tank 56 due to a failure of the water supply valve or the water level sensor, the tub cover 70 may overflow due to a relatively large amount of washing water that overflows. Washing water is guided to the guide ribs (78a, 78b) and the relatively low portion (A) in which the drainage hole is formed to be drained through the drainage hole 74 to prevent the washing water from overflowing suddenly. have.

Next, when the washing and rinsing stroke is completed as described above, while the inner tank 55 and the pulsator 58 are rotated at the same time at high speed, the washing water is separated from the laundry by centrifugal force to perform a dehydration stroke.

The tub cover structure of the washing machine according to the present invention configured as described above is stored when the amount of washing water overflows is small, and is fixed to allow the natural evaporation and drainage when the amount of washing water overflows. As the drain hole is formed, the washing water is naturally evaporated or immediately drained according to the amount of the overflowed washing water, so that no foreign matter is filtered out, so that the mold can be kept clean as well as the structure is simplified. Simplification has the advantage of lowering production costs.
