A tubular spray element for a dishwasher is rotatably supported and/or supplied with fluid at an intermediate location along the length of the tubular spray element, such that least one aperture that directs fluid into a wash tub is disposed on each side of the intermediate location. In addition, a tubular spray element drive may be positioned externally from the wash tub and mechanically coupled to the tubular spray element through a shaft seal such that the fluid supply to the tubular spray element can be entirely within the wash tub.

Systems, methods, and computer program products for monitoring a level of product (14) in a reservoir (10, 130, 140, 190, 260) of a chemical dispensing system. A lid (22, 148, 216, 302, 358) configured to engage an opening (28, 136, 138, 146, 204, 352) of a container (12, 198, 354) includes a level sensor (26, 244, 272, 342, 386) having a transceiver (36) that transmits an output signal (38) and receives a portion of the output signal (38) reflected back (42) to the transceiver (36). The level sensor (26, 244, 272, 342, 386) determines an amount of the product (14) in the container (12, 198, 354) by comparing a characteristic of the reflected signal (42), such as time the reflected signal (42) was received, to the characteristic of the output signal (38), such as the time the output signal (38) was transmitted. The level sensor (26, 244, 272, 342, 386) may also determine the size of the container (12, 198, 354) based on the reflected signal (42), and take this size into account when determining the amount of product (14) in the container (12, 198, 354). The level sensor (26, 244, 272, 342, 386) transmits product level data to a mobile device (54) in response to receiving an interrogation signal (66) therefrom.

A system for dispensing a detergent solution from a solid detergent into a dishwasher includes a dispenser that can collect water sprayed into the dishwasher and use the collected water to produce the detergent solution by dissolving a portion of the solid detergent, controlling the amount of the detergent solution produced, and releasing the produced detergent solution between cleaning cycles. The dispenser can perform these functions automatically without being electrically powered.

A fluid dosing mechanism may include a dosing vessel, a dosing cylinder, a dial, and a piston. The dosing vessel defines a fluid chamber. The fluid chamber includes an inlet and an outlet. The dosing cylinder is coupled to the dosing vessel and defines an end slidable within the fluid chamber. The dial is rotatably coupled to the dosing cylinder and configured to slide the dosing cylinder to define a dosing volume within the fluid chamber against the end of the dosing cylinder. The dosing volume is fluidically coupled to the inlet and the outlet. The piston is movable between (i) a retention position to retain fluid in the dosing volume and (ii) a discharge position to discharge fluid from the dosing volume of the fluid chamber through the outlet. A cart assembly may include a fluid dosing system including a system housing and the fluid dosing mechanism.

A washing agent dispenser for washing machines has a dispenser body that comprises a fixed dispenser part (200), designed for mounting on a wall delimiting a washing machine wash-chamber (3), and a removable dispenser part, couplable in a removable way to the fixed dispenser part (200). The removable dispenser part comprises a hollow body defining a tank for a substance in liquid or semi-solid form, with a first wall of the hollow body which is intended to face at least partially a second wall of the fixed dispenser part (200).

The dispenser (10) also comprises a sensor device (270), configured to provide an electrical signal representative of at least one of a level and a qualitative characteristic of the substance contained within the at least one tank. The sensor device (270) is arranged at least partly on the fixed dispenser part (200).

A method of operating a household appliance having a treating chamber and a single-use dispenser with a siphon. The method comprising fluidly coupling the siphon to the treating chamber when supplying water to the single-use dispenser, and fluidly coupling the siphon to a bulk treating chemistry reservoir when water is not supplied to the single-use dispenser.

A dispensing apparatus for an appliance includes a housing assembly which defines a loading chamber and a dispensing chamber. The dispensing chamber is separate from the loading chamber within the housing assembly. The dispensing apparatus includes a corkscrew coil rotatably mounted in the loading chamber of the housing. A motor is coupled to the corkscrew coil. Additionally, there is a first door positioned at a first opening defined by the housing assembly at the loading chamber. The first door is configured to selectively open and close the first opening. A second door positioned at a second opening is defined by the housing assembly at the chute. The second door is configured to selectively open and close the second opening.

A dispensing apparatus for an appliance includes a housing. The housing defines a loading chamber. A corkscrew coil is rotatably mounted in the loading chamber, and a motor is coupled to the corkscrew coil. Additionally, a chute defines an opening at an end of the corkscrew coil.

The dispenser can perform these functions automatically without being electrically powered.

A detergent dispensing apparatus 3 used for a dish washer and a dish washer comprising the detergent dispensing apparatus 3. The detergent dispensing apparatus 3 comprises a liquid storage box, a liquid outlet pump 32 and a pipeline module. The liquid storage box comprises a first half housing and a second half housing, and the first half housing and the second half housing fixedly connect each other in a first direction so as to define a liquid storage cavity used for storing detergent. The liquid outlet pump 32 is configured to suction the detergent from the liquid storage cavity and dispense the detergent to the exterior of the detergent dispensing apparatus 3. The pipeline module comprises a liquid adding channel used for adding the detergent to the liquid storage cavity, a liquid inlet channel used by the liquid outlet pump 32 for extracting the detergent from the liquid storage cavity, and a liquid outlet channel used by the liquid outlet pump 32 for dispensing the detergent. The second half housing defines at least a portion of a pump accommodating space that is used for accommodating the liquid outlet pump.
