A rack assembly comprising a frame; and a fixing rack coupleable to the top of the frame. The fixed rack comprises: a housing forming an outer contour of the fixing rack, the housing including a bottom surface that is at least partially open; a plurality of horizontal ribs, formed on the bottom surface of the housing, and spaced apart from each other; and a plurality of vertical ribs formed on the bottom surface of the housing perpendicular to the plurality of horizontal ribs, and spaced apart from each other, and the fixing rack has a region that is curved along a direction parallel to the plurality of vertical ribs.

A dishwasher is provided that may include a tub configured to define a washing space in which a washing object is washed, the tub having an open side, a first accommodating rack configured to accommodate the washing object inside of the tub, the first accommodating rack being unloadable from the tub, and a door configured to selectively open and close the open side of the tub, the door supporting the first accommodating rack when the first accommodating rack is unloaded. The tub may include a first protrusion protruding from an inner sidewall of the tub toward the washing space so as to support the first accommodating rack and guide movement of the first accommodating rack, and a second protrusion provided above the first protrusion and protruding from the inner sidewall of the tub toward the washing space so as to prevent the first accommodating rack from being lifted upward when the first accommodating rack is unloaded.

A dishwasher having a treating chamber with one or more sprayers through which liquid is recirculated into the treating chamber, whereby the impact of the spray emitted from the sprayers impacts the structure forming the treating chamber to generate noise. Damping material is applied to structure forming the treating chamber to reduce the sound level of the impact exterior of the dishwasher.

A dishwasher includes a wash tub, a lower basket, a first upper basket, a second upper basket, and movement parts. The wash tub defines a space in which dishes are washed. The lower basket is disposed in the wash tub. The first upper basket is disposed over the lower basket inside the wash tub to define a first lower reception space together with the lower basket. The second upper basket is disposed over the lower basket side by side with the first upper basket to define a second lower reception space. The movement parts move the first upper basket above or below the second upper basket to increase the first lower reception space.

A dishwasher appliance and a method for mounting a slide rail within a dishwasher appliance are provided. A rack assembly of the dishwasher appliance includes a bracket with a post. A slide rail is mounted to the bracket, and the slide rail and the bracket are positioned within a wash chamber of the dishwasher appliance. The post extends through the tub, and a sleeve is positioned opposite the bracket on the tub and engages the post. The sleeve hinders retraction of the post through the tub.

A dishwasher includes: a tub including a washing room; and a dryer installed on one side of the tub, the dryer including: a first housing coupled with the tub and communicating with the washing room; a second housing coupled with an other side of the first housing, and forming a flow path together with the first housing so that inside air of the washing room circulates back to the washing room by passing through the flow path; a heater accommodated inside the first housing and the second housing to heat the air passing through the flow path; and a switch module positioned upstream of the heater, configured to detect an inside temperature of the flow path to turn on or off the heater based on the detected inside temperature, and fixed between the first housing and the second housing by coupling of the first housing with the second housing.

A rack for a domestic dishwasher includes a frame and a base. The base can be swung and folded out in order to increase a loading volume of the rack. The base includes a first portion articulated to a first side of the frame via a first articulation, and a second portion articulated to a second side of the frame opposite the first site via a second articulation, and articulated to the first portion via a third articulation. The second portion is configured to change its length between the second and third articulations.

A lower rack for a domestic dishwasher is constructed for being liftable and includes a fixed lower rack element, and a removable lower rack element connectable to the fixed lower rack element and constructed for removal from the fixed lower rack element to thereby unblock access to a bottom area of a washing container of the domestic dishwasher.

A dishwasher appliance includes a caloric heat pump system that is configured for heating and cooling a wash chamber of a tub. A field generator is positioned such that caloric material stages are moved in and out of a field of the field generator during operation of the caloric heat pump system. A pump circulates a heat transfer fluid between a first heat exchanger, a second heat exchanger and the caloric material stages.
