Description

Dehydration Rinsing Equipment of Drum Washing Machine

The present invention relates to a drum washing machine which automatically washes, dehydrates and dries by a drop generated by the rotation of the drum. More specifically, when dewatering, a certain amount of water is sprayed for a predetermined time to re-rinse laundry. It relates to a dewatering rinsing device of a drum washing machine configured to be loaded.

As shown in FIG. 1, a general conventional drum washing machine is provided with a detergent container 3 and an operation unit 15 on an upper portion of the front surface of the washing machine body 1, and is not shown on the rear surface of the washing machine body 1. Hot and cold water supply valves 7 and 8 are installed to be connected to the water pipes to supply hot and cold water.

A tub 9 is installed in the washing machine body 1, and a drum 11 is installed in the tub 9 to wash at a high speed.

The front of the tub 9 is provided with a door 13 to open and close the opening of the drum 11 when the laundry cloth is put into the drum 11, the drying of the laundry cloth on the top of the tub (9) An air band 17 is installed to introduce dry air during the stroke, and a counterweight 19 is provided on the front surface of the tub 9 to suppress vibration generated by the high speed rotation of the drum 11 during washing and dehydration. Is installed.

A heater 21 is installed in the air band 17 to heat-exchange the air introduced from the outside into hot air, and the high heat generated by the heater 21 is transferred to the drum 11. Fan motor 23 is installed to cause air convection by supplying to the outside, and a condensing hose 25 for supplying cold water to condense hot air introduced into the tub 9 is provided on the outer circumferential surface of the tub 9. It is connected.

The lower side of the tub 9 is provided with a driving means 27 for generating power for forward and reverse rotation of the drum 11, the washing water in the tub 9 on the lower rear side of the washing machine body (1). The drain pump 31 for forcibly draining to the outside is connected to the drain hose 29, between the drain pump 31 and the tub (9) washing waste contained in the wash water drained from the tub (9) A filter 33 for filtering the filter 33 is provided.

The driving means 27 is a motor 27a, a motor pulley 27c formed on the shaft 27b of the motor 27a, and the power transmitted by the belt 27d on the vertical image of the motor pulley 27c. It consists of a pulley 27e inserted to rotate the drum 11

However, in the conventional washing machine formed as described above, washing, rinsing, and dehydration and drying are automatically performed due to a drop caused by the rotation of the drum 11. When the washing machine performs washing and dehydration after washing for a predetermined time period, When washing and rinsing, the detergent and the foreign matter contained in the laundry are not completely removed, there is a problem that the washing power is not good.

The present invention has been made to solve the above problems, an object of the present invention is to provide a dewatering rinsing device of the drum washing machine to improve the washing power by re-rinsing the laundry by supplying water during the dehydration administration.

Dehydration rinsing apparatus of the drum washing machine according to the present invention made to achieve the above object, after washing and rinsing the laundry while the drum rotates in the tub by the power transmitted from the drive means to the drum washing machine to dehydrate and dry The dehydration rinsing means is provided on the outer side of the tub to re-rinse the laundry in the drum by supplying water for a predetermined time during the dehydration stroke through the rotating shaft formed on one side of the drum.

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

In the drawings, the same components as those in the related art are denoted by the same names and the same reference numerals, and detailed description thereof will be omitted.

As shown in Figure 3, in the dewatering and rinsing apparatus of the drum washing machine according to the present invention, the reference numeral 100 supplies water for a predetermined time during the dehydration stroke through the rotating shaft 110 formed on one side of the drum (11) Dewatering rinsing means are provided on the outside of the tub 9 to rinse the laundry in the drum 11 again.

The dewatering rinsing means 100 is bound to one side of the drum 11 and penetrated therein and rotated according to the rotation of the driving means 27 to rotate the drum 11, and the rotating shaft ( Injection means 120 for injecting water supplied into the drum 11 into the drum 11 and the inside of the drum 11 so that the water injected from the injection means 120 is radially sprayed in the drum 11. Consists of a plurality of injection holes 130 formed on the convex surface.

The injection means 120 is an injection pipe installed in the rotary shaft 110 to inject the water flowing through the water supply hose 121 into the drum 11 through the injection port 130 in accordance with the opening and closing of the water supply valve 122 123 and a bearing 124 inserted between the injection pipe 123 and the rotating shaft 110 to rotate the rotating shaft 110 without being fired, and the bearing 124 of the bearing 124. The packing member 125 is hermetically inserted so that water introduced into the drum 11 through the spray pipe 123 is not flowed backward and does not flow out of the rotating shaft 110, and the spray pipe 123 is supported. It consists of a support member 126 is bound to the outside of the tub (9).

The drive means 27 is transmitted by a motor 27a, a motor pulley 27c formed on the shaft 27b of the motor 27a, and a belt 27d on a vertical line of the motor pulley 27c. It consists of a pulley 27e inserted into the outer circumferential surface of the rotating shaft 110 to rotate the drum 11 by power.

Next, the operation and excess of the present invention thus constructed will be described in detail.

The drum 11 is rotated in the tub 9 during the washing operation, and the laundry in the drum 11 is pulled up and dropped at the same time, and washing is performed by the drop, and several rinsing is performed after washing. After rinsing, dehydration and drying are performed.

In particular, during dehydration, the power of the motor 27a rotates the pulley 27e through the belt 27d, and this rotation rotates the rotating shaft 110 of the drum 11 to dehydrate the laundry in the drum 11. At the same time, the water supply valve 122 is opened for a predetermined time during the dehydration stroke, and the water is sprayed into the drum 11 through the injection pipe 123 through the water supply hose 121 to dehydrate the laundry at the same time. By re-rinsing, the degree of dehydration is improved.

That is, water is supplied only for a predetermined time during the dehydration administration to rinse the laundry, and after the water supply for a predetermined time, dehydration is performed in a state where the water supply valve 122 is closed.

As described above, according to the dewatering and rinsing apparatus of the drum washing machine according to the present invention, the laundry is re-watered at the same time as the dehydration by reconfiguring the spray water into the drum through the injection pipe in accordance with the opening and closing of the water supply valve during the dehydration operation. Rinsing can improve rinsing power and dehydration.
