The present invention relates to a dishwasher. The dishwasher of the present invention comprises: a tub open at one side thereof and forming a space in which dishes are washed; a base disposed under the tub and spacing the tub a predetermined distance apart from the bottom surface; a door opening/closing the open side of the tub; a lower cover extending forward from the front end of the base and covering the lower side of the tub; and a light source part disposed above the lower cover to emit light, wherein the light source part comprises a lamp which emits light and a housing by which the lamp is fixedly placed while being spaced a predetermined distance upward apart from the lower cover, and the lower cover has a light source hole formed therethrough, the light source hole being open in the vertical direction below the lamp.

A control method of an appliance, including: the appliance includes a first unit that includes a first lamp, a first cavity, a first door and a first sensor; a second unit that includes a second lamp, a second cavity, a second door and a second sensor; and a controller that controls operations of the first unit and the second unit, includes sensing vibrations generated in any one of the first unit or the second unit by the first sensor and the second sensor; determining whether the sensed vibrations are caused by a knock, and when determining that the sensed vibrations are caused by a knock using the first sensor and the second sensor, transferring a knock-on signal to the controller; and comparing the knock-on signals received from the first sensor and the second sensor and determining which of the first unit or the second unit is given the knock by the controller, and outputting a lamp-on output signal to the first unit or the second unit in which the knock is generated by the controller.

The present disclosure relates to an appliance. The appliance includes; a main body that has a first accommodation space therein, and a first sensing module that is disposed at the main body in a way that the first sensing module is disposed outside the first accommodation space. Since a sensor is disposed to avoid the effect of heat as described above, the sensor is much less likely to operate improperly or be broken because of heat.

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.

The invention proposes a dishwasher comprising a working chamber (2), comprising at least one spray arm (5, 6) which is arranged in a rotatable manner in the working chamber (2), and comprising a metering apparatus (9) for supplying and metering a substance, such as detergent, rinse aid etc., into the working chamber (2), wherein the metering apparatus (9) is designed as an insert part (9) comprising a housing (20, 21) for insertion into a recess in an inner wall (7) of the working chamber (2), for example in the door (7) of the warning chamber (2), and comprising a sensor unit (27, 28) for identifying a spray arm movement in the working chamber (2) of the dishwasher, which sensor unit is arranged at least partially in a housing (20, 21) of the metering apparatus (6), wherein the dishwasher has improved program control. According to the invention, this is achieved in that at least one inlet opening (17) in an interior (22) of the metering apparatus (9) is arranged at least partially in the jet (23) of water/liquid from a spray nozzle (24) of the spray arm (5, 6) during the rotation of the spray arm (5, 6), wherein the sensor unit (27, 28) is arranged at least partially in the/on the interior (22) and/or on a wall of the interior (22).

The invention proposes a dishwasher comprising a working chamber, comprising at least one spray arm which is arranged in a rotatable manner in the working chamber, and comprising a metering apparatus for supplying and metering a substance, such as detergent, rinse aid etc., into the working chamber, which metering apparatus is designed as an insert part comprising a housing for insertion into a recess in an inner wall of the working chamber, for example in the door of the working chamber, and comprising a sensor unit for identifying a spray arm movement in the working chamber of the dishwasher, which sensor unit is arranged at least partially in a housing of the metering apparatus, wherein the sensor unit 11 comprises at least one infrared transmitter 12 and/or one infrared receiver 13.

An out-of-product alarm process includes initiating an out-of-product check by sending a signal to a controller from an optical sensor assembly connected to a fluid delivery medium for delivering a product to a fluid dispensing site, performing an out-of-product check, running an alarm cycle with the controller after receipt of an out-of-product signal, and executing a corrective action. Performing the out-of-product check includes directing light into the fluid delivery medium, generating a detector output based on detected light within the fluid delivery medium, determining an out-of-product state within the fluid delivery medium based on a comparison of the detector output to an out-of-product threshold, starting an out-of-product timer, when the out-of-product state is determined, and determining an out-of-product event when the out-of-product timer reaches a threshold out-of-product time period.

A washing agent dispenser for washing machines comprises a fixed dispenser part (200) and a removable dispenser part (100). The removable dispenser part (100) comprises a hollow body (101) defining a tank for a washing agent. The tank has, in a lower part thereof, an outlet (112), in a back wall of the hollow body (101), which is couplable in a separable way to an inlet (210) at the front of the fixed dispenser part (200). A retention valve (230.sub.1) is mounted on the hollow body (101), in a position corresponding to the outlet (112) of at the tank. The retention valve (230.sub.1) is configured to assume a respective open position following upon coupling between the outlet (112) and the inlet (210), and to assume a respective closed position following upon uncoupling between the outlet (112) and the inlet (210).

A laundry treating appliance having a trating chamber and a bulk dispenser and a user interface configured to provide an indication to the user related to the bulk chemistry dispenser and a controller coupled with the user interface and the bulk treating chemistry dispenser and configured to execute an operating cycle including controlling the treating chemistry meter to dispense the predetermined amount of treating chemistry and determine a number of doses of treating chemistry available in the bulk treating chemistry dispenser and method of determining the number of doses and the types of a treating chemistry available in the bulk dispensing system, and providing an indication of the determination on a user interface.

A dish washer includes: a tub configured to receive an object to be washed and providing a washing space having an opening at a front side of the tub, a door configured to rotate relative to the tub between (i) a closing position that closes the opening of the washing space and (ii) a full opening position that exposes an entirety of the opening of the washing space, a door position sensor configured to sense a position of the door, a dry air supply configured to selectively generate a high-temperature dry air or a low-temperature dry air and supply the high-temperature dry air or the low-temperature dry air into the tub, and a controller configured to determine, based on the position of the door sensed by the door position sensor, whether to supply the high-temperature dry air or the low-temperature dry air.
