An automatic door opening system suitable for use in an electrical device having a body with an inner chamber, a door hinged to the body from one side, and a processing unit, the automatic door opening system having a rod that allows the door to open by applying a pushing force to the door while moving in a forward direction, and allows the door to be released when the rod brings into the backward position by moving in the backward direction.

A dishwashing appliance may include a cabinet, a door, and a sensor assembly. The cabinet may extend along a lateral direction between a first side and a second side. The cabinet may define a wash chamber for receipt of articles for washing. The door may extend along a vertical direction between a top end and a bottom end. The door may be rotatably mounted to the cabinet to move along a rotation path between an opened position and a closed position. The sensor assembly may be attached to the cabinet to detect a positional angle of the door. The sensor assembly may include a wave emission sensor directed at the rotation path to project an emitted wave and a wave reception sensor spaced apart from the wave emission sensor to receive a reflection of the emitted wave.

A dishwashing appliance includes a tub defining a wash chamber and a door rotatably mounted to the tub. The door is configured to rotate between an open position and a closed position. A user interface mounted on the door, and a controller is in signal communication with the user interface. A pulley is mounted to the tub and a cord is coupled to the door. The cord configured to rotate the pulley when the door is rotated between the open position and the closed position. A magnet is mounted to the pulley. The magnet is configured to rotate with the pulley as the door is rotated. A sensor is mounted to the tub proximate the pulley. The sensor is configured to detect the position of the magnet, and the controller is configured to disable the user interface based at least in part on the position of the magnet.

A dishwashing appliance may include a cabinet, a tub, a spray assembly, a circulation pump, a pressure sensor, and a controller. The circulation pump may be in fluid communication with a wash chamber defined by the tub. The pressure sensor may be upstream of the circulation pump. The controller may be configured to initiate a washing operation including activating the circulation pump, detecting movement of the door from a closed position, detecting return of the door to the closed position, calculating a modified time period for flood detection, determining pressure at the pressure sensor exceeds a pressure threshold following detecting return of the door to the closed position, initiating the modified time period in response to determining pressure at the pressure sensor exceeds the pressure threshold, and directing the circulation pump based on measuring the elevated pressure and expiration of the modified time period.

The invention relates to a low cost sensor array suitable for use in a ware washing machine, preferably a dish washing machine. The invention also relates to a standalone detergent dispensing device comprising the low cost sensor array. The sensor systems are intended to allow monitoring of wash cycles such that controlled sequential dosing of reagents in wash cycles can be optimized. A device comprising such a sensor system may then be able to sense the conditions of the wash and dose reagents in their optimal sequence in the wash.

A dishwasher, in particular a household dishwasher, includes a mechanism for modifying odor. The mechanism for modifying odor includes an ozone generator for odor neutralization in a dishwasher cavity and a system for fragrance introduction into the dishwasher cavity. A control device has stored therein a process, which firstly provides for the odor neutralization by the ozone generator and then introduction of a new fragrance by the system for fragrance introduction.

A dishwasher includes a dishwasher interior for washing items to be washed with washing liquor. Arranged at a lower end of the dishwasher interior is a pump sump for collecting the washing liquor, and a sensor is arranged in the pump sump for outputting a sensor signal as a function of a presence of washing liquor at the sensor. A control apparatus configured to carry out a washing program selected from a number of washing programs is designed to determine a malfunction of a component of a hydraulic assembly as a function of the sensor signal and of a current operating state of the dishwasher.

Dishwashing machine comprising: a controller; a spray arm assembly comprising a spray arm having one or more spray holes for spraying a washing load with water, and a pipe for delivering water to the spray arm; a pump for pumping water through the pipe and to the spray arm; the pipe being constructed and arranged to at least partially restrict flow of water from the pump to at least a part of the spray arm dependent on spray arm orientation relative to the pipe, a power consumption of the pump thereby being dependent at least in part on the spray arm orientation relative to the pipe; and the controller being configured to monitor the power consumption of the pump in order to determine rotational information of the spray arm.

A dishwashing appliance and methods for operating the same may provide a cabinet, a tub, a door, a spray assembly, a heating element, and a controller. The door may be rotatably mounted to the cabinet to move between a fully-open position, a preset open-vent position, and a closed position. The preset open-vent position may be between the fully-open and closed positions. The spray assembly may be positioned within the wash chamber. The heating element may be mounted within the cabinet in thermal communication with the wash chamber. The controller may be configured to initiate a dry cycle. The dry cycle may include moving the door from the closed position, determining the door is in the preset open-vent position following moving the door from the closed position, and activating the heating element to generate heat within the wash chamber following moving the door from the closed position.

A dishwasher capable of shortening drying time is disclosed. The present device comprises: a main body having a washing tub provided therein; a door rotatably coupled to the main body so as to open and close the washing tub; a blowing duct having a passage provided between the outside of the washing tub and the inside of the main body so as to provide a flow path through which the air flowing from the outside flows, and a discharge port provided at the passage so as to spray air to the outside; and a blowing means connected to the blowing duct so as to provide the external air into the blowing duct, and forcibly causing wet steam in the washing tub to flow to the front of the main body, wherein the passage has at least one variable section for changing the cross sectional area thereof.
