Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a display screen and a household appliance with the display screen. Background Art

[0002] Dishwashers are automated devices that automatically clean tableware such as bowls, chopsticks, plates, and dishes. As people's living standards improve, dishwashers are also used by more and more families. They can reduce the labor intensity of users, improve work efficiency, promote cleanliness and hygiene, and meet the user's comfortable life experience. The working principle of a dishwasher is to use a motor to drive a washing pump to spray detergent from a sprayer under a certain pressure to form a dense hot water flow in a three-dimensional direction. The sprayer rotates due to the reaction force of the water spray, so that the detergent is evenly sprayed onto the tableware in the dishwasher, and the tableware is sprayed and rinsed in a three-dimensional manner.

[0003] At present, the display screen of the dishwasher is generally fastened to the door body by screws or buckles to form an integrated complete structure, and the display screen is generally installed vertically. When users use the dishwasher, they often need to bend down to better operate the display screen; and the height difference of family members is large. When different members operate, the optimal tilt angle of the display screen is different. Therefore, the current display screen cannot meet the needs of all family members and does not conform to ergonomics.

[0017] In some embodiments of the present application, a limiting end of the limiting column extends out of one end of the limiting hole, and the limiting end can be rotated and moved upward.

[0018] In some embodiments of the present application, the display screen has a hinged end and a movable end arranged opposite to the hinged end, and when the display screen leaves the position of the initial state, the movable end moves toward a direction close to the center of the installation slot.

[0019] In some embodiments of the present application, the limiting protrusion has a first arc-shaped slope whose protrusion height gradually increases in the direction close to the bottom of the installation groove, and a second arc-shaped slope whose protrusion height gradually decreases in the direction close to the bottom of the installation groove.

[0020] In some embodiments of the present application, the limiting protrusion further has an arc-shaped wave crest connected between the first arc-shaped slope and the second arc-shaped slope.

[0021] In some embodiments of the present application, an extension surface of the arc-shaped wave crest intersects with a rotation axis of the display screen body.

[0022] In some embodiments of the present application, the limiting protrusion is extended toward the rotation axis direction of the display screen body.
