  • the protective panel 60 may be a light guide plate made of a light transmitting material, which serves to transmit the light emitted from the operation indicator 53 in a forward direction of the door 40.
  • the transparent protective panel 60 may function not only to prevent deformation of the external structure 1 due to steam discharged from the dishwasher 10, but also to transmit the light, emitted from the operation indicator 53 arranged on the upper surface 41 of the door 40, in a forward direction of the door 40.
  • the protective panel 60 may have at least one diffuser pattern 67 integrally formed at an upper surface 65 thereof to diffuse the light directed from the operation indicator 53 to the protective panel 60.
  • the diffuser pattern 67 may function to reflect or refract the light introduced through the incidence surface 61 of the protective panel 60, to transmit the light to the emission surface 63 of the protective panel 60.
  • the diffuser pattern 67 may be provided at the upper surface 65 of the protective panel 60 at a position facing the operation indicator 53 arranged on the upper surface 41 of the door 40.
  • the diffuser pattern 67 may take the form of a V-shaped recess indented inward from the upper surface 65 of the protective panel 60, to refract or reflect the light introduced into the protective panel 60 at a predetermined angle.
  • the diffuser pattern 67 in the form of a triangular recess reflects or refracts the light that have emitted from the operation indicator 53 and introduced into the protective panel 60 through the incidence surface 61 and thus, causes condensation of the light emitted from the emission surface 63, enhanced forward brightness and visibility may be accomplished.
  • a plurality of diffuser patterns 67 may be spaced apart from one another in a front-and-rear direction F of the protective panel 60, and more particularly, may be equidistantly arranged as illustrated in FIG. 5A .
  • a plurality of diffuser patterns 67 may be arranged such that a distance S between the neighboring diffuser patterns 67 is reduced away from the operation indicator 53, i.e. toward the emission surface 63.
  • Some of the diffuser patterns 67 adjacent to the operation indicator 53 receive a sufficient quantity of light emitted from the operation indicator 53, but the quantity of light introduced into the remaining diffuser patterns 67 is reduced away from the operation indicator 53. Therefore, when reducing the distance S between the neighboring diffuser patterns 67, it may be possible to increase the quantity of light to be emitted from the emission surface 63 and consequently, enhance visibility of the user.
  • the shape of the diffuser patterns 67 is not limited to the above description.
  • the diffuser patterns 67 may have a curved cross sectional shape.
  • the diffuser patterns 67 integrally formed at the upper surface 65 of the protective panel 60 it may be possible to effectively irradiate the light emitted from the operation indicator 53 through the emission surface 63 in a forward direction of the door 40.
  • a reflective sheet 69 may be provided at the incidence surface 61 of the protective panel 60 located between the operation indicator 53 and the emission surface 63. Once the light emitted from the operation indicator 53 is introduced into the incidence surface 61 of the protective panel 61, the reflective sheet 69 prevents the light from leaking from the incidence surface 61 rather than being directed toward the emission surface 63.
  • the reflective sheet 69 may be formed at the incidence surface 61 by a silk screen method using paste containing materials exhibiting a high degree of reflectivity.
  • the present embodiment illustrates the diffuser patterns 67 as being formed at a partial region of the upper surface 65 of the protective panel 60 to correspond to the operation indicator 53, as illustrated in FIG. 6 , at least one diffuser pattern 67 may be elongated in a direction of the protective panel 60 designated by the arrow W.
  • the diffuser patterns 67 may be unnecessary to form the diffuser patterns 67 to correspond to the operation indicators 53 in a one to one ratio.
  • the dishwasher 10 begins to be operated.
  • the operation indicator 53 emits light corresponding to a current operating state of the dishwasher 10.
  • the dishwasher 10 since the dishwasher 10 is embedded in the receiving space 3 of the external structure 1, the outer appearance of the dishwasher 10 is hidden by the external structure 1 once the door 40 is closed, but the light emitted from the operation indicator 53 is introduced into the incidence surface 61 of the protective panel 60 attached to the ceiling 5 of the receiving space 3. Thereby, as the light is directed to the emission surface 63 so as to be emitted to the outside, the user may perceive an operating state of the dishwasher 10.
  • the diffuser patterns 67 diffuse the light passing through the protective panel 60, the user visibility may be further enhanced.
  • the high-temperature steam contacts the protective panel 60 attached to the ceiling 5 of the receiving space 3. Accordingly, it may be possible to prevent the high-temperature steam from directly contacting the external structure 1, thereby preventing deformation of the external structure 1.
  • the protective panel 60 of the present embodiment may serve not only to prevent the high-temperature steam within the dishwasher 10 from directly contacting the external structure 1, but also to allow the user to perceive a current operating state of the built-in dishwasher 10 from the outside.
  • the diffuser patterns 67 may be integrally formed at the protective panel 60 and this may enhance productivity of the protective panel 60.
  • a built-in dishwasher may allow a user to easily perceive a current operating state of the dishwasher from the outside.
  • the built-in dishwasher according to the embodiment may prevent deformation of an external structure in which the dishwasher is embedded, thus providing enhanced reliability in operation.
