Abstract

The present invention relates to a washing machine spray device of a drum washing machine, a conventional drum washing machine is washed by the impact of the washing water filled in the lower portion of the washing tank as the laundry falls in the upper direction by the rotation of the washing tank of the pulsator The washing power is very inferior to the fully automatic washing machine which washes by rotational flow, and especially when there is a lot of laundry, the force of falling of the laundry is weaker and the number of collisions with the washing water accumulated in the lower part is very poor. In addition, since the water flow of the washing water introduced into the washing tank is not formed, there is a problem that the dissolution of the detergent added is not sufficiently achieved. The present invention sprays high-pressure washing water onto the laundry to be washed by the rotation of the washing tank to wash. As this progresses, the tangles of the laundry are reduced. By reducing the damage to the laundry to increase the washing ability of the laundry, and also to increase the degree of dissolution of the detergent to reduce the amount of detergent used.

Description

Washing water jet device of drum washing machine {APPARATUS FOR JETTING WATER IN DRUM WASHING MACHINE}

The present invention relates to a drum washing machine, and more particularly, to a washing machine spraying device of a drum washing machine, which not only increases washing power of laundry but also dissolves the added detergent.

In general, as shown in FIG. 1, a drum washing machine includes an outer case 10 having a predetermined inner space formed therein and a pedestal 1 coupled to a lower surface thereof, and a damper 20 inside the outer case 10. The outer washing tank 30 which is supported and installed by), the washing tank 40 which is located inside the outer washing tank 30 and is loaded with laundry, and is installed on the lower surface of the outer washing tank 30 to drive force Drive motor 50 to generate a, and is connected by the washing tank 40 and the shaft 61 and connected by the drive motor 50 and the belt 62 to drive the driving force of the drive motor 50 to the washing tank 40 Pulley 60 to be delivered to, and the door 70 is installed on the opposite side where the pulley 60 is located, and a water supply pipe is installed to communicate with the upper portion of the outer washing tank 30 so that washing water and detergent flows in ( 11) and the detergent container 12, and the drain pump 51 is installed in the lower portion of the outer washing tank (30) It is configured to include a drain hose (13).

In addition, the washing tub 40 has a predetermined thickness and has a cylindrical shape having a plurality of through holes 41 formed therein, and the inner circumferential surface of the cylinder has blades 42 having a predetermined thickness and height at regular intervals.

Reference numeral 21 is a spring for supporting the outer washing tank 30 from the top.

The operation of the drum washing machine including the components as described above is as follows.

First, the laundry is put into the washing tank 40 and a predetermined amount of detergent and washing water is introduced through the detergent container 12 and the water supply pipe 11, and then the driving motor 50 is operated by the operation signal. The driving force is transmitted to the pulley 60 through the belt 62 so that the pulley 60 rotates, and the rotational force of the pulley 60 is transmitted to the washing tank 40 by the shaft 61 so that the washing tank 40 As you rotate, you wash your laundry. The laundry put into the washing tub 40, as shown in Figure 2, rotates with the washing tub 40 as the washing tub 40 rotates and drops in the upper direction while the detergent is accumulated in the lower portion of the washing tub 40 Washing is done by repeating collisions and inflows with the mixed wash water.

However, in the conventional drum washing machine as described above, since the laundry is dropped from the upper direction by the rotation of the washing tub 40, the washing is performed by the collision with the washing water filled in the lower part of the washing tub 40, so that the rotational flow of the pulsator Compared to the automatic washing machine, which is washed by the washing machine, the washing power is not very low, and in particular, when there is a lot of laundry, the force of falling of the laundry is weaker, and the number of collisions with the washing water accumulated in the lower part decreases. there was.

In addition, since the water flow of the washing water introduced into the washing tank 40 is not formed, the dissolution of the added detergent is not sufficiently made, and thus the utilization of the detergent is reduced, and the washing power is also reduced.

The object of the present invention devised in view of the problems described above is to provide a laundry water spraying apparatus of a drum washing machine that not only increases the washing power of laundry but also dissolves the detergent.

Hereinafter, the operational effects of the drum washing machine washing water injection device of the present invention will be described.

First, the laundry is put into the washing tank 40 and the detergent and washing water are injected through the detergent container 12 and the water supply pipe 11 to fill the outer washing tank 30 with a predetermined amount, and then the driving motor 50 is operated by the operation signal. When the driving force of the drive motor 50 is transmitted to the pulley 60 through the belt 62, the pulley 60 is rotated, the rotation of the pulley 60 is rotated by the shaft 61 washing tank 40 It is delivered to) to wash the laundry while the washing tank 40 rotates. In addition, the drain motor 92 is also operated, as shown in FIGS. 4A and 4B, when the impeller 93 is rotated in the clockwise direction, the washing is filled in the outer washing tank 30 by the rotation of the impeller 93. A part of the water flows into the impeller chamber N through the inlet hose 94 to rotate the impeller chamber N. The on-off valve 96 blocks the outlet of the drain hose 95 by the washing water flow. Washing water flow is pumped to the connection hose (100). The washing water pumped into the connection hose 100 is sprayed through the flow path 81 and the spray nozzle 83 of the washing water spraying means 80 and evenly sprayed to the laundry to be washed in the washing tank 40 at high pressure. In addition, the washing water spraying means 80 rotating together with the washing tank 40 serves as a laundry net or a rod, thereby reducing the entanglement of the laundry and causing the laundry to impinge with the washing water spraying means 80. Will increase.

And when draining the wash water, if the drain motor 92 is rotated in reverse, as shown in Figure 5, the impeller 93 is rotated in the counterclockwise direction to the counterclockwise rotation of the impeller 93 Part of the washing water filled in the outer washing tank 30 is introduced into the impeller chamber (N) through the inlet hose 94 to rotate the impeller chamber (N) and was blocking the drain hose (95) by the wash flow. The on / off valve 96 rotates to open the outlet of the drain hose 95 to block the outlet of the connection hose 100 and at the same time the water flow is pumped to the drain hose 95 to drain the water.

According to the present invention, the laundry is rotated together with the washing tub 40 and the laundry is dropped in the upward direction as in the prior art, and the washing water pumped by the impeller 93 is applied to the laundry through the washing water spraying means 80. It also sprays into the laundry and reduces the tangling of the laundry, thereby increasing the washing capacity and reducing the washing variation.

In addition, since the detergent injected with the washing water is pumped by the impeller 93 together with the washing water, the degree of dissolution is high.

As described above, the washing water spraying device of the drum washing machine according to the present invention by spraying the high-pressure washing water to the laundry to be washed by the rotation of the washing tank to proceed with the washing and to reduce the tangling of the laundry In addition to increasing the washing ability, there is an effect to improve the performance and reliability of the product by reducing the damage to the laundry.

In addition, by increasing the degree of dissolution of the detergent has the advantage of reducing the amount of water used to reduce the amount of detergent.
