Abstract: A method of operating an ice maker appliance includes directing liquid water to a mold body of the ice maker appliance. The method also includes determining that at least a portion of the liquid water escaped based on at least one of an ice making time, a harvest motor torque, or a temperature change rate. The method further includes providing a user notification in response to determining that at least the portion of the liquid water escaped.

Abstract: An appliance including a cabinet, a mount unit, and an ice tray is provided. The cabinet forms a freezer chamber and the mount unit is positioned in the freezer chamber. The mount unit forms a channel configured to releasably receive the ice tray. The ice tray includes a lip corresponding to the channel at the mount unit. The mount unit includes a rotor configured to rotate along a central axis.

Abstract: A refrigerator appliance may include a cabinet, a door, an image module, and a shelf assembly. The cabinet may define a chilled chamber. The door may be rotatably hinged to the cabinet to provide selective access to the chilled chamber. The image module may be mounted to the cabinet. The shelf assembly may be disposed below the image module within the chilled chamber. The shelf assembly may include a support panel attached to the cabinet, a first shelf attached to the support panel, a second shelf attached to the support panel and spaced apart from the first shelf, and a weight sensor mounted on the support panel to detect stored mass at the first shelf and the second shelf.

Abstract: An appliance including a cabinet forming a chamber. A track is attachable to the cabinet in the chamber. The track includes a pair of track arms at which a sensor is attached. A member extends between the pair of track arms, and an opening is formed at the member. A shelf includes a pair of support arms at which a frame is positionable. A mounting end of the support arms forms a tooth insertable into the opening at the track.

Abstract: An ice maker appliance includes a mold body configured for receiving liquid water and for forming ice from the liquid water within the mold body and a collection tray below the mold body along a vertical direction. The collection tray defines an internal volume. The collection tray is positioned and configured to capture and retain an escaped portion of the liquid water from the mold body in the internal volume of the collection tray.

Abstract: A vacuum cleaner includes a suction nozzle including a housing that defines an inlet, a first shaft disposed at a side of the housing, a driver configured to rotate the first shaft, a rotating brush that extends along an axis and is configured to, based on rotation of the first shaft, rotate about the axis to thereby move dust on a surface to toward the inlet, a detachable cover configured to rotatably support a first end of the rotating brush, and a second shaft disposed at a second end of the rotating brush and configured to engage with the first shaft to rotate the rotating brush. The first shaft and the second shaft are configured to contact each other and to define first contact surfaces that have a spiral shape about the axis and that are configured to transfer rotational force from the first shaft to the second shaft.

Abstract: An ice making system for creating clear ice and an associated method are provided. The ice making system employs a first sealed refrigerant system connected to a heat exchanger. A second sealed refrigerant system is also connected to the heat exchanger for cooling a first refrigerant of the first sealed refrigerant system. A heat exchanger heater is at least partially contained with the heat exchanger for heating the first refrigerant. A pump in the first refrigerant system is activated after heat exchanger heater has warmed the first refrigerant, enabling a cooling cycle to begin. Once sufficient clear ice has been generated, the pump is deactivated.

Abstract: A vacuum cleaner includes a main body and a suction nozzle that suctions up dust on the floor. The suction nozzle includes a housing, a driver, and a rotating brush. The housing includes an entrance through which the dust travels to the main body, a first shaft member, and a first rib disposed along a circumference of the first shaft member. The rotating brush includes a cylindrical body rotated by the first shaft member. The rotating brush also includes a brush member attached to an outer surface of the cylindrical body. The brush member rubs against the floor to direct the dust on the floor towards the entrance. As the brush member rotates, it also comes into contact with the first rib. The brush member includes a plurality of filaments. Some of the filaments are elastically deformed in the direction of the rotation axis upon contacting the first rib.

Abstract: A method of making clear ice includes circulating a refrigerant through a refrigerant loop. A portion of the refrigerant loop is in contact with a mold body. Thus, the refrigerant chills the mold body. The method also includes spraying a first volume of liquid water into a mold cavity of the mold body. As a result, a first volume of ice is formed in the mold cavity. The method also includes spraying a second volume of liquid water into the mold cavity after the first volume of ice has formed. Thus, a portion of the first volume of ice is melted and a second volume of ice is formed in mold cavity. The clear ice includes an unmelted portion of the first volume of ice and the second volume of ice.

Abstract: A vacuum cleaner is disclosed. The vacuum cleaner according to the present disclosure includes a main body and a suction nozzle. The suction nozzle includes a housing, a driver, a rotating brush, and a detachable cover. A pressing button is mounted in the housing. The detachable cover is rotated about the rotational axis of the rotating brush to be mounted in the housing. The pressing button selectively blocks rotation of the detachable cover.
