Abstract
Provided is a dishwasher capable of reducing a vibration noise of a housing by providing a curved portion having a curvature in a housing of a tub forming a washing tub.
The dishwasher includes a main body forming an outer appearance, a tub provided inside the main body and having a washing tub for washing dishes, and a spray nozzle provided inside the tub for spraying washing water through the utensil, And a vibration damping material adhered to the outside of the housing to reduce the vibration of the housing by the washing water sprayed from the injection nozzle, wherein the housing has a height protruding outward toward the center portion And a curvature frame having a curvature.
Description
The present invention relates to a housing shape of a dishwasher.
In general, a dishwasher includes a main body forming an outer appearance, a tub provided inside the main body, a tub having a washing tub, a dish basket provided inside the washing tub, a spray nozzle for spraying washing water to the dish basket, To the injection nozzle.
The washing water sprayed from the spray nozzle is sprayed by the tableware housed in the dish basket to wash the dishware. Part of the washing water sprayed from the spray nozzle is sprayed directly onto the housing forming the washing tub, thereby hitting the wall surface of the housing.
Vibration is generated in the housing by the washing water striking the wall surface of the housing, thereby generating vibration noise.
In order to reduce vibration noise of the housing, a vibration damping material for reducing vibration is attached to the outside of the housing. To increase the rigidity of the housing, a plurality of beads are provided in the housing.
However, vibration generated by a low frequency of 1000 Hz or less is mainly reduced by a vibration damper rather than a plurality of beads provided in the housing. Therefore, in order to reduce vibration, the vibration damper must be made thick and the efficiency of vibration reduction is reduced do.
Therefore, it is necessary to deform the shape of the housing so that the vibration of the housing can be efficiently reduced while minimizing the thickness of the vibration damping material adhered to the outside of the housing.
One aspect of the present invention provides a dishwasher capable of reducing vibration noise of a housing by providing a curved portion having a curvature in a housing of a tub forming a washing tub.
A dishwasher according to an embodiment of the present invention includes a main body for forming an outer appearance, a tub provided inside the main body and having a washing tub for washing dishes, a spray nozzle provided inside the tub for spraying washing water with the utensils, Wherein the tub comprises a housing forming the washing tub, and a damping material adhered to the outside of the housing and reducing the vibration of the housing by the washing water sprayed from the spray nozzle, And a curvature frame having a curvature such that a height protruding toward the curvature frame is increased.
The curvature frame may be provided on left and right and rear sides of the housing, respectively.
The curvature frame may include a planar portion and a curvature portion having a curvature protruding outward from the planar portion towards the center and having an elliptical shape.
The curvature portion may be provided in a curved surface having a curvature in each of a transverse direction and a longitudinal direction, and may have a maximum height at which a central portion protrudes outwardly.
The center of the curvature portion may protrude from the flat portion to a height of 5 mm to 15 mm in the outward direction.
Wherein the curvature portion has a maximum length in the transverse direction greater than 0.85 times the transverse length of the planar portion and smaller than a transverse length of the planar portion, the maximum length in the longitudinal direction being greater than 0.85 times the length in the longitudinal direction of the planar portion May be smaller than the length of the planar portion in the longitudinal direction.
According to another aspect of the present invention, there is provided a dishwasher including a housing, a washing tank provided inside the housing for washing dishes, a spray nozzle provided inside the washing tank for spraying washing water with the tableware, And a curvature frame protruding convexly so as to have a curvature that increases in height toward the outer side toward the central portion is provided on the side surface and the rear surface.
And a vibration damping material for reducing vibrations of the housing by washing water sprayed from the injection nozzle is adhered to the outside of the housing. The curvature frame is provided with a flat portion and a curved portion protruding from the flat portion to have a curvature, And adhesion can be facilitated.
According to the embodiments of the present invention, the vibration noise of the housing can be reduced while the thickness of the vibration damping material adhered to the housing is reduced.
In addition, it is possible to facilitate the adhesion of the vibration damping material while effectively reducing the vibration noise of the housing, and to improve the injection flow of the washing water sprayed from the spray nozzle.
