The present invention relates to the improvement of the rack on which the dishwasher is placed in the automatic dishwasher, and more particularly, to a rack having a height change device that can easily achieve the height change of the rack.

In the rack of the conventional automatic washing machine, as shown in FIG. 2, the wheels 1 and 2 are attached to the lower and middle parts so as to receive selective rolling guidance along the rails 3 installed in the front and rear directions on the left and right inner walls of the washing machine body. Doing.

However, such a rack height selection structure is inconvenient to raise and lower the rack. The rack must be pulled out completely to raise or lower the rack.

In this process, the damage caused by the collision between the wheel and the rail is also concerned.

The present invention allows to easily select the height of the rack in consideration of the advantages, it features a rack with a height change device that can be raised or lowered immediately in place to be washed without lifting the rack.

The rack height change device proposed by the present invention has a vertically guided male rail that can move along an existing rail, and the male rail is fitted with a slider type lifting plate that can be moved up and down vertically. The rail plate surface between the projection jaw necessary for fixing the lifting plate at a high position and the lifting plate is provided with the engaging pieces to be caught on the projection jaw, respectively, the plate surface between the arm rails of the lifting plate is elastic by the removed position .

The elasticity of the plate surface acts as an element that allows the locking jaw to be locked in position with the protruding jaw given a position where the locking jaw can be changed in the surface direction of the plate surface.

When the rack stayed in the lower position is pushed up vertically, the height of the rack is fixed to the height from the moment when the latching jaw of the lifting plate is caught above the protruding jaw of the bogie and the upper position is fixed. If it is pulled inward and the jammed jaw is left out of the protruding jaw of the bogie, the rack will go down by itself by its own weight, and then the lower position from the moment when the bottom of the platform touches the trolley top of the bogie Staying stable, rack height selection is very easy and quick, and rack and related elements are safe from damage during these rack changes.

Hereinafter, one preferred embodiment of the present invention will be described in detail.

The main idea of the present invention lies in the combination of the bogie 10 and the elevating plate 20. The trolley 10 is composed of a pulley 12 having wheels 11 at the front and back of the inner surface and a lay plate 13 perpendicular to the upper surface of the pulley 12, and at the front and rear ends of the rail plate 13 A vertical male rail 15 is formed, and an inwardly protruding jaw 14 is provided near the upper end of the inner surface of the rail plate 13.

Among these elements, all except the wheel 11 form a unitary structure.

Then, the bottom surface of the projection jaw 14 is sloped upward toward the front surface so that the locking jaw described later does not obstruct much.

On the other hand, the lifting plate 20 is to support the rack 30 while moving up and down vertically along the male rail 15, the front and rear ends of the plate surface 21 is formed with a vertical arm rail 22 bent backwards The lower end of the wavefront 21 has a handle 23 extending inwardly along its longitudinal direction.

In addition, on the plate surface slightly raised from the handle 23, there is a locking piece 24 in the form of punching and tilting backwards, one at each front and back.

Then, on the plate surface where the arm rail 22 begins, the seat 25 is vertically cut from the lower end to the vicinity of the upper end so that the plate surface 21 has a predetermined elasticity.

The back of the plate 26 extending from the arm rail 22 is also provided with hooks 27 and 28 to hang the upper and lower portions of the left and right sides of the rack 30.

The trolley 10 is simply installed by fitting the wheel 11 to the existing rail 3 installed on the inner side of the washing machine left and right, the lifting plate 20 is the female rail of the trolley 10 with the arm rail 22. It is also simply installed if it is guided in (15).

Thus, when assembling the lifting plate 20 to the trolley 10, if the lower end of the locking piece 24 is caught on the protruding jaw 14, the rack 30 is in a high position, the handle 23 in a high position When pulled inward, the plate surface 21 also moves in that direction, causing the locking piece 24 to escape the protruding jaw 14.

Then, the lifting plate 20 can move down to a lower position without being restrained by the protruding jaw 14.

On the other hand, when moving from a low position to a high position, simply pushing the rack 30 can easily achieve the purpose.

The lifting plate 20 is vertically raised together with the rack 30, and then the locking piece 24 and the plate surface 21 are moved due to the contact pressure therebetween as the locking piece 24 touches the inclined bottom surface of the protruding jaw 14. Retracts elastically toward the inner side and returns to its original shape as soon as it leaves the protruding jaw 14, so that the lower end of the engaging piece 24 is caught on the upper surface of the protruding jaw 14, and thus the posture of the rack 30 is elevated. Is stabilized.

In order to further secure the ascending and descending postures of the elevating plate 20 and the assembling posture with the trolley 10, an auxiliary rail 16 may be further provided on the inner surface of the male rail 15 to guide the cut 25. have.

As described above, the rack height adjustment device of the present invention can be easily changed without raising the rack as it is simply lifted up as it is or by a simple operation of releasing the jam by the handle of the lifting plate. Also, when the rack height is changed, there is little damage due to contact of related elements, so it is safe.

Claims (1)

The rail plate 13 is placed on the pulley 12 with the known wheels 11 guided by rails provided on the inner surfaces of the right and left walls of the dishwasher body, and the male rail 15 is placed at the front and rear ends of the rail plate 13. In addition, the inner surface of the upper end of the rail plate 13 is provided with an inwardly projecting jaw 14, the front and rear of the lifting plate 20 to form an arm rail 22 which is guided to the male rail 15 On the lower surface of the plate surface 21, the handle 23 and on the upper plate surface thereof is formed a locking piece 24 to be caught on the protruding jaw 14, and from the lower end to the tubular portion on the arm rail 22 side, Rack height change device of the automatic dishwasher having the seat (25) up to near the top to make the plate elastic.
