A dish washer according to an embodiment of the present invention includes a cabinet which forms a dish washing space; a door which opens and closes an opened front surface of the cabinet; wherein door includes an out plate which is made of metal plate material and forms the front surface of the door and at least a portion of appearance of a peripheral surface of the door by being bent the front surface, an operating unit which is formed on the peripheral surface of the door so that a user operates by touch, a PCB assembly which is in close contact with a rear surface of the operating unit and on which a plurality of touch sensors detecting displacement of the operating unit are mounted, a mounting bracket which is mounted to be fixed to an inside surface of the out plate, and an elastic member which is mounted on the mounting bracket and presses and supports the PCB assembly to the a rear surface of the operating unit.

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.

Disclosed herein is a dishwasher including a main body provided with an open hole and a washing tub; a door configured to open or close the open hole; a door opening/closing member configured to open or close the open hole; an air curtain disposed in the main body, to operate a fan such that ambient air is sucked and the sucked air is discharged; a detector configured to detect information of the fan; and a controller configured to diagnose the failure of the fan based on the detected information of the fan, to control an operation of the door opening/closing member such that the door is opened at a predetermined open time and an open time of the door is delayed when the fan is a failure state, and to control an operation of the fan when the fan is a normal state during a drying operation.

An automated cleaning machine may include one or more short cleaning cycles in which the duration of a cleaning cycle is shortened relative to the duration of a default cleaning cycle. During a short cleaning cycle, other cleaning cycle parameters may also be adjusted to ensure that the articles subjected to the short cleaning cycle are adequately cleaned and sanitized. For example, the wash temperature, rinse temperature, and/or cleaning product amounts or concentrations, may be adjusted to account for the shortened duration of the cleaning cycle. The automated cleaning machine may further include one or more short cycle mode(s) during which short cleaning cycle parameters are used and one or more default cycle mode(s) during which default cleaning cycle parameters are used.

An automated dosing method for dosing a chemical in a tunnel dishwasher includes the steps of: detecting a rinse signal from a supplying solenoid valve for supplying a rinse water of the dishwasher; dosing a detergent amount apt to be inserted in a washing liquid, at a first load configuration of the dishwasher, for obtaining a washing mixture; and dosing a further detergent amount, apt to be inserted in the washing liquid for a restoration of the detergent in the washing mixture at an operating configuration of the dishwasher. The dosing step of a further detergent amount is performed periodically according to a predetermined time frequency.

A method for the process programming of a household appliance includes the following steps: receiving a sequential program by the household appliance; checking the sequential program with respect to a predetermined device condition by the household appliance; and releasing the sequence of the sequential program in the household appliance as a function of the result of the check.

A method for cleaning items to be cleaned is disclosed. A cleaning device is used that has at least one cleaning chamber and at least one applicator for applying at least one cleaning fluid to the items to be cleaned in the cleaning chamber. A desired hygiene value is prespecified. The method further includes time-resolved recording of at least two influencing variables which influence hygienization of the items to be cleaned. Hygiene share values are determined from the influencing variables using a prespecified relationship between each influencing variable and the respective hygiene value share of said influencing variable. An expected actual hygiene value at the end of the cleaning from the hygiene value shares is ascertained and compared with the desired hygiene value. At least one of the influencing variables is changed based on the comparison. An inventive cleaning device is also disclosed.

A warewash machine includes in-situ tank soil load reduction that involves at least one of: (i) prior to addition of fresh water, draining the collection tank via a path that exits the collection tank at a location lower than a primary overflow path until wash liquid level in the collection tank drops below a standard operating level, and thereafter adding fresh water; or (ii) draining the collection tank via a path that exits the collection tank at a location lower than a primary overflow path while simultaneously adding fresh water; or (iii) adding fresh water such that wash liquid level in the collection tank rises above a standard operating level, and thereafter carrying out draining of the collection tank.

The present invention relates to a home appliance, in particular, a dishwasher, a washing machine or the like, and a method for controlling said home appliance. The home appliance comprises a water supply unit including a water supply port, for supplying water, like fresh water or drinking water to the home appliance, a water reservoir for storing water supplied to the home appliance by the water supply unit, a treatment space for treating objects in the home appliance, like dishes or laundry, at least one pump unit for circulating water inside the treatment space and for discharging water from the treatment space and a control unit for controlling the operation of the home appliance. In the inventive home appliance, a heat exchanger is arranged between the water supply unit and the water reservoir, for exchanging heat between the water supplied to the reservoir and the water discharged from the treatment space by the at least one pump unit.

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.
