Description

[0001] The present invention relates to a household appliance wherein the height is adjusted by adjusting the feet thereof supporting the body thereof.

[0002] In household appliances such as dishwashers, washing machines or refrigerators, the height of the feet which carry and support the body of the appliance may require to be adjusted. The household appliance is balanced by adjusting the height of the feet. Particularly, built-in household appliances may require height adjustment after being placed in a cabin.

[0003] The height adjustment of the feet can be made by rotating the foot around its axis by means of a wrench. In most cases, the height adjustment of the rear feet is enough to adjust the height of the appliance. For example, when the height of the appliance needs to be adjusted due to relocation, repair, or maintenance, removing multiple bearings and working on the housing may take more time than necessary for the service personnel.

[0004] Therefore a practical, quick and effective process of height adjustment is required for avoiding longer maintenance times. Therefore, adjustment mechanisms are provided in the state of the art, where the rear feet can be adjusted from the front of the household appliance. The rear feet are enabled to be adjusted by means of the adjustment shaft extending from the front of the household appliance toward the rear foot. However, in the case of feet located in the middle, the shaft extending from front to rear narrows the space allocated for components mounted on the casing or restricts the movement of the shaft. This creates arrangement problems.
