Technical field

The present application relates to the field of dishwasher technology, and in particular to a height adjustment mechanism for a dishwasher and a dishwasher including the same.

Background technique

The dishwasher is a device that automatically cleans dishes, chopsticks, plates, dishes, knives, forks, and the like. The dishwasher includes a casing, a liner disposed on the casing, and a bowl basket connected to the inner tank, and the used tableware such as a bowl, a tray, or the like is placed on the bowl to realize the cleaning of the tableware.

However, when the user places a non-standard large-sized tableware on the upper basket, the large-sized tableware may touch the top of the liner, and the bowl basket needs to be moved downward. At this time, if the bowl is fixed to the inner liner, it is difficult to clean the large-sized tableware.

To this end, the Chinese patent document CN106691350A discloses a dishwasher basket adjustment structure, a handle is arranged on the bowl basket, a positioning member is arranged on the handle, and a positioning screw is connected to the inner wall of the dishwasher chamber, and the screw itself is positioned. It is a "Z" shape. When the bowl is required to be in a higher position (high position) of the dishwasher chamber, the bowl is pushed upward, and the positioning screw first pushes the positioning member to rotate until the positioning screw rotates to a high position that needs to be stopped, the handle will be in the spring. Under the action of the positioning member, the positioning member moves toward the inside of the positioning member, and the positioning member moves to the inside of the positioning screw rod. At this time, the positioning member supports the positioning screw to prevent the positioning screw from falling; when it is necessary to put a large-sized dinner plate, even if When the bowl basket is in the lower position (low position) of the dishwasher chamber, the user manually turns the handle, and the handle will drive the positioning member to rotate away from the position of the positioning screw, because the positioning screw loses the limit, so the bowl The basket will fall under the action of gravity, thus completing the movement from high to low.

However, in the above documents, in order to realize the positioning of the positioning screw, it is necessary to bend the positioning screw into a shape of "Z" or the like, and the processing is complicated. At the same time, during the movement from the low position to the high position of the bowl basket, the positioning member is always under the dual action of the upward pushing of the positioning screw and the downward pressing of the spring, and the positioning member is easy to move relative to the positioning screw. Once the positioning member is disengaged from the positioning screw, the bowl cannot be moved to a high position.

Summary of the invention

Therefore, the technical problem to be solved by the present application is to overcome the defects that the basket height adjusting mechanism in the prior art is complicated to process and is prone to failure.

To this end, the present application provides a dishwasher comprising: a liner having a receiving cavity for holding a bowl basket; a bowl basket movable relative to the inner tank between a high position and a low position; the regulating piece fixed at The adjusting piece has a limiting end; the adjusting bracket is fixed on the bowl, the adjusting bracket has a sliding groove for inserting the limiting end, and the sliding groove has a high phase with the bowl a corresponding first limit point and a second limit point corresponding to the lower position of the bowl basket; a triggering member rotatably disposed on the adjusting bracket, the triggering member having the adjusting bracket at the sliding position a first state of the slot, abutting against the limit end of the tab to maintain the bowl in a first state of high position; and rotating and disengaging the limit end to cause the adjustment bracket a second state of moving to a lower position to bring the limit end into contact with the second limit point.

The adjustment bracket includes: a body; a vertical mounting slot connected to the body, the bracket mounting slot is configured to be embedded in the interior of the bowl, and the body is mounted on the adjusting bracket And the bracket mounting groove is disposed on both sides of the trigger member.

The body is provided with a limiting slot for accommodating a rotating shaft, and the triggering member is coupled to the rotating shaft by a torsion spring, and the torsion spring is configured to provide the said basket when moving from a low position to a high position The trigger member rotates to a pushing force above the limit end.

The adjustment bracket further includes: a horizontal mounting groove disposed on the body, the horizontal mounting groove being embedded at a horizontal portion of the bowl when the adjustment bracket is mounted on the bowl.

The horizontal mounting groove and the vertical mounting groove are provided with an undercut for clamping the bracket mounting groove on the wire of the bowl.

The trigger member is an adjustment handle, and the handle includes an abutting portion that contacts the limit end of the adjustment bracket, and a pressing portion that acts by an external force.

a finite structure is disposed on the abutting portion, and when the triggering member rotates under the action of the torsion spring, the limiting structure can be in contact with the body of the adjusting bracket to prevent the abutting portion from rotating excessively .

A side of the adjusting piece remote from the limiting end is provided with a plurality of vertically distributed buckles, and the adjusting piece is connected to the bowl by the buckle.

The side of the adjusting piece away from the bowl is provided with a plurality of rollers, and the roller is divided in a vertical direction, comprising a first roller set disposed above and a second roller set disposed below; Two horizontal beams are disposed opposite to the biliary, the horizontal beam is sandwiched between the first roller set and the second roller set, and the bowl can be accommodated under the limitation of the horizontal beam Horizontal motion occurs in the cavity.

The technical solution of the present application has the following advantages:

1. The dishwasher provided by the present application completes the adjustment of the bowl between the high position and the low position by the action between the trigger member, the regulating piece and the adjusting bracket. The adjusting bracket and the bowl basket move synchronously, the adjusting bracket is connected with the triggering member, the triggering member functions as a switch, and the adjusting piece is fixed by itself. When the bowl basket is at a high position, the triggering member abuts against the limiting end of the adjusting piece, The bowl with the adjustment bracket and the follower is also in the upper position. When it is necessary to lower the basket from the high position to the low position, only the trigger member needs to be rotated, and the trigger member is disengaged from the limit end. Since the bowl basket is relatively at a higher position, the bowl basket will be adjusted under its own gravity. The bracket and the trigger member are dropped.

In the present application, the limiting end of the adjusting piece is always embedded in the sliding groove, which can stabilize the up and down movement of the adjusting bracket and improve the stability of the movement of the bowl.

At the same time, the adjusting bracket is used as a transition piece, and its self-structure is simple and convenient for manufacturing, and at the same time, a sliding groove is arranged thereon, which can stabilize the regulating piece.

2. The dishwasher provided in the present application, because both sides of the trigger member are limited, such a setting manner can greatly improve the stability of the trigger member during the rotation process, thereby effectively preventing the trigger member from shaking relative to the limit end of the regulating piece. To prevent the occurrence of restrictions on the control piece failure.
