Description

Dishwasher {Dish Washer}

The present invention relates to a dishwasher, and more particularly, to a dishwasher in which a door can move in a vertical direction.

A dishwasher is a kitchen appliance that washes contaminants such as food residues on dishes, cooking utensils, etc. (hereinafter, 'to be washed') by high-pressure washing water sprayed from a jet arm.

A dishwasher is a device for washing dishes used in the kitchen and is disposed in a space of the kitchen. Recently, in order to utilize the space of the kitchen, a built-in dishwasher in which the dishwasher is installed in a built-in form in the sink has been used.

Referring to FIG. 1 , since the sizes of sinks S1 and S2 are not standardized, a difference may occur with the size of the built-in dishwasher 1 ′. Since the height H1 of the door 2 of the dishwasher 1' and the height H2 of the lower cover 3 have a structure that is generally not variable, the difference between the heights of the sinks S1 and S2 is reduced. can have

If the size of the dishwasher and the sink do not match in this way, a gap (D1, D2) may occur between the top of the sink (S1, S2) and the top of the dishwasher (1') or between the bottom of the sink and the bottom of the dishwasher. have. The gaps D1 and D2 formed between the upper end of the sink and the upper end of the dishwasher do not appear integrally with the sink and may occur as a factor impairing the aesthetics. In addition, a gap formed between the sink and the dishwasher may cause a problem in terms of cleanliness in which dust gets caught or a problem in safety in which a user's hand may get caught.

Japanese Laid-Open Patent Publication No. JP2006280552A discloses a configuration in which a gap between the sink and the dishwasher is removed by adjusting the top of the dishwasher installed as a built-in.

However, the prior literature discloses a structure in which a gap between the sink and the dishwasher is removed by placing a separate structure on the upper end of the dishwasher, and thus the problem of appearance cannot be solved. In addition, in the disclosed configuration, the arrangement of the structure is fixed by placing only the uneven portion, but there is a problem in that the structure is difficult to be stably fixed in the disclosed configuration.

Japanese Patent Application Laid-Open No. JPH08336495A discloses a configuration for adjusting the lower end of a dishwasher installed as a built-in. However, in the above structure, as a part of the door moves downward, it may cause a problem in that the opening and closing of the door is not smooth.

A first object to be solved by the present invention is that a dishwasher installed in a sink adjusts the arrangement of doors according to the size of the sink, thereby removing a gap between the sink and the dishwasher, and unifying the appearance of the sink and the dishwasher. to provide a washing machine.

A second object of the present invention is to provide a dishwasher including a separate lower cover for removing a gap between the dishwasher and the bottom of the sink or between the floor.

A third object is to provide a dishwasher capable of removing a gap between the door and the lower cover in a structure in which the arrangement of the door and the lower cover is changed.

A fourth object is to provide a dishwasher capable of rotating the door without changing the rotation axis of the door even when the lower cover moves upward.

The problems of the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, according to an embodiment of the present invention, a tub is formed to wash dishes in a dishwasher and has an open front; and a door rotatably disposed in front of the tub. The door may include an inner door having a constant height and an outer door having a variable height by being coupled to the inner door so as to adjust the height of the front surface of the dishwasher to fit sinks having different heights for each product. .
