The present invention relates to a door opening device of a dishwasher, and more particularly, a door opening device of a dishwasher, which prevents the door from being opened rapidly and improves durability and at the same time increases the reliability of the speed of opening. It is about.

In general, the door that is installed to open and close the washing room of the dishwasher is in the use characteristics that should be easy to put and take out the dish, the bottom of the front of the body is condensed from the top to the bottom direction.

In addition, since the door is provided with a holding means for keeping the airtight in a closed state in order to prevent leakage during the operation of the dishwasher, its own weight becomes relatively heavy.

Therefore, such an effect of the self-weight and the drop force generated during the opening is a factor to open the door rapidly, there is known a device for preventing the shock generated during the opening process of the door and to reduce the opening speed.

1 and 2 show an example of such a conventional device, where one end of the wire 3 is bound to the hinge side 2, and the other end of the wire is provided with a spring 5 provided on the body 4 of the washer. ) To be tensioned, and the wire is configured to be guided by the roller (6).

Thus, the device is rapidly opened by the load when pulled to open the door 1, the drop force of the door being generated, i.e. the rotational moment, to the tension of the spring 5 connected to the wire 3 By offsetting, the force equilibrium is maintained.

By this action, the door is opened at a constant speed, thereby preventing the shock due to rapid opening. However, since the conventional device has a structure that is decelerated by using the tension of the spring, there was a limit that the rotation moment can not be quickly adapted to the change that is frequently changed according to the opening angle of the door, in particular, the greater the weight of the door, the deceleration There were problems that drastically dropped.

In addition, when the fatigue accumulates due to the long-term repeated use, the set tension is lost, resulting in the lack of reliability and durability.

The present invention has been made in view of the above problems of the conventional apparatus, and an object thereof is to provide a door opening device for a dish washer that operates smoothly in response to a change in force generated during the opening of the door.

Another object of the present invention is to provide a door opening device of a dishwasher that improves the reliability and durability of the operation.

The objects of the present invention are achieved by allowing the opening speed of the door to be compensated by the action of the link member and the slider.

In other words, the gears fixed to the hinge shaft of the door and the gears fixed to the body of the washing machine are interlocked to interlock the link members, and the sliders installed on the guard rail are operated by the displacement of these link members, thereby smoothly opening and closing the door. And it will perform an accurate deceleration action, and to be able to flexibly respond to the change in force according to the weight and opening angle of the door.

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

3 is a view showing an opening device according to an embodiment of the present invention, the drive gear 12 is condensed to the hinge shaft 11 of the door 10, and the body 20 of the washer to be rotated in engagement with the drive gear. The driven gear 22 is affixed to the pin shaft 21. Then, the pin shaft 21 of the driven gear 22 is one end of the operation 30 is condensed, the other end of the operation between the first slidingly coupled to the guide groove 41 formed in the first link (40) It is condensed to the slider 50.

Moreover, the lower end part of the 1st link 40 is condensed by the pin shaft 21 'to the mother body 20, and the upper end part is condensed to the one end part of the 2nd link 60. As shown in FIG. In addition, the other end of the second link 60 is axially connected to the second slider 70 which is slidably coupled to the guide rail 80 installed in the body 20.

Accordingly, when the door 10 is opened, the driving gear 12 rotates together, thereby rotating the driven gear 22 engaged therewith.

In this case, since the position of the operation section 30 is displaced in proportion to the rotation angle of the driven gear 22, the first slider 50, which is condensed at the other end between the operations, is guide groove 41 of the first link 40. Is slid on the floor.

Accordingly, the primary deceleration occurs in the process of the rotational force initially generated by the opening of the door 10 is converted into a linear motion.

In addition, since the first link 40 is displaced by the deformation force generated when the first slider 50 is slid in the guide groove 41, the first link has a pin shaft 21 축 attached to the lower end as an axis. To rotate in the direction of the force.

By this action, the first link 40 rotates the second link 60. In this case, the second slider moves the second slider 70 connected to the end of the second link. Sliding at 80) to perform the secondary deceleration action.

As such, the operations of the first and second links 40 and 60 and the first and second sliders 50 and 70 are sequentially and organically performed to each other, so that the door 10 is open from the beginning to the end. Maintain a uniform opening speed.

In addition, since the rotational force generated by the opening and closing of the door is transmitted by the interlocking action of the gears, the influence is minimized even when the weight of the door and the moment of force is large, and deformation due to repeated use is also prevented.

This invention has the advantage that the reliability of the operation is improved because it maintains the opening and closing speed of the door uniformly and accurately, the failure or malfunction is prevented even in long-term use and the durability is improved.
