A dishwasher includes a tub defining a wash chamber, a wash rack provided within the wash chamber, an air inlet in fluid communication with the wash chamber at a first position, an air exhaust outlet in fluid communication with the wash chamber at a second position different from the first position, a first gas sensor provided in the dishwasher, and a controller configured to initiate an operation sequence. The operation sequence includes initiating a drying cycle, receiving an air-quality signal from the first gas sensor, measuring, during the drying cycle, an air-quality characteristic within the wash chamber of the dishwasher, determining the measured air-quality characteristic is below a predetermined air-quality threshold, calculating a drying time in response to determining the measured air-quality characteristic is below the predetermined air-quality threshold, and halting the drying cycle in response to an expiration of the drying time.

The present disclosure relates to a dish washer having a heat pump, and the dish washer may include a washing tank provided with a sump at a bottom surface thereof and provided with an accommodation space for storing dishes therein; a heat pump system provided with an evaporator, a compressor that compresses and circulates refrigerant, a condenser that heats washing water for washing the dishes, and an expansion apparatus; and a heat exchange system that exchanges heat between water for heat transfer to the refrigerant and the evaporator, thereby enhancing the heat exchange performance and efficiency of the evaporator.

A dishwasher appliance can include a basket configured for receipt of articles for washing and a camera assembly mounted within the wash chamber with a view of a rack assembly. A controller is operably coupled with the camera assembly and may be configured for obtaining an image of the rack assembly positioned in the wash chamber, determining whether the basket is positioned in the rack assembly, and adjusting at least one operating parameter of the dishwashing appliance based on whether the basket is positioned in the rack assembly.

Systems and/or methods for the monitoring and/or control of thermal sanitization in automated cleaning machines are described. A cleaning machine controller may predict a number of heat unit equivalents that will be delivered during a cleaning process based on a sump temperature difference (i.e., a change in the temperature of the cleaning solution in the sump) experienced at or near the beginning of the cleaning process. One or more cleaning process parameters may be adjusted and/or controlled based on the sump temperature difference in order to ensure that a target number of heat unit equivalents are delivered in order to achieve thermal sanitization of the wares subjected to the cleaning process.

A dishwasher includes a tub defining a wash chamber, a wash rack provided within the wash chamber, an air inlet in fluid communication with the wash chamber at a first position, an air exhaust outlet in fluid communication with the wash chamber at a second position different from the first position, a first gas sensor provided in the dishwasher, and a controller configured to initiate an operation sequence. The operation sequence includes initiating a drying cycle, receiving an air-quality signal from the first gas sensor, measuring, during the drying cycle, an air-quality characteristic within the wash chamber of the dishwasher, determining the measured air-quality characteristic is below a predetermined air-quality threshold, calculating a drying time in response to determining the measured air-quality characteristic is below the predetermined air-quality threshold, and halting the drying cycle in response to an expiration of the drying time.

A dishwasher, in particular a domestic dishwasher, includes a control device configured to perform a number of washing programs for washing items to be washed, and an input means configured to register a user input for shortening a running selected washing program. The control device is configured to adjust the running selected washing program as a function of a registered user input in such a manner that a remaining washing time of an adjusted selected washing program is shortened compared with a regular remaining washing time of the running selected washing program.

Provided herein are a method of controlling operation of a washing appliance and a washing appliance being controlled by the method. The method may include displaying, on a user interface of the washing appliance, an estimated duration of a selected washing program for the washing appliance; displaying, on the user interface, a degree of ecological impact caused by the selected washing program; allowing a user to operate the user interface to change the duration of the selected washing program, wherein the washing appliance adapts the selected cleaning program to comply with the changed duration; and displaying on the user interface the degree of ecological impact caused by the selected washing program when complying with the changed duration.

A washing and drying unit configured to perform at least one of washing, drying, and sterilizing, or any combination thereof includes at least one sensor configured to determine a dimension and/or shape of the object, a washing and/or sterilizing apparatus and a drying and/or sterilizing apparatus configured to direct at least one apparatus or spray of a washing and/or sterilizing or a drying and/or sterilizing fluid to the object, at least one robot arm connected to at least one of the apparatuses, and a controller operable to orient and move the at least one robot arm. A separate sterilization apparatus may be included and the sterilization may include using electrified water or water that has been exposed to ultraviolet light. The controller orients the at least one robot arm based on the dimension and/or shape determined by the at least one sensor.

The present disclosure relates to a dish washer having a heat pump, and the dish washer may include a washing tank provided with a sump at a bottom surface thereof and provided with an accommodation space for storing dishes therein; a heat pump system provided with an evaporator, a compressor that compresses and circulates refrigerant, a condenser that heats washing water for washing the dishes, and an expansion apparatus; and a heat exchange system that exchanges heat between water for heat transfer to the refrigerant and the evaporator, thereby enhancing the heat exchange performance and efficiency of the evaporator.

A dishwasher including a tub forming a washing chamber; a drying device disposed outside of the tub and including an inlet through which air from the washing chamber is introduceable, a flow channel in which air from the washing chamber introduced through the inlet flows, a fan that is operable to cause air from the washing chamber to be introduced through the inlet to flow in the flow channel, a heater in the flow channel to heat air in the flow channel, an outlet through which air in the flow channel is discharged to the washing chamber, and a temperature sensor between the heater and the outlet; and at least one processor configured to operate the fan based on a start of a drying cycle and to determine an initial operation time point of the heater during the drying cycle based on temperature detected by the temperature sensor.
