A dishwasher includes: a dishwasher body including a tub that defines a washing space and a sump disposed vertically below the tub and configured to accommodate washing water; a heat pump including a compressor, a condenser, an expansion apparatus, and an evaporator; a drain storage unit connected to a drain pipe of the sump and configured to receive washing water discharged from the sump; a drain pipe open-close valve that opens and closes the drain pipe; and a controller that controls the heat pump and the drain pipe open-close valve. The evaporator is configured to exchange heat with the drain storage unit, and the controller controls the drain pipe open-close valve to open the drain pipe to move washing water of the sump to the drain storage unit when the sump is drained.

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.

A water-using household appliance, in particular a household dishwashing machine, includes a wall which is made from a metal material, and a device which is made from a plastic material and fixedly connected to the wall by a laser weld.

A dishwasher comprising a tub, a reuse tank, and a controller for implementing a wash cycle in the tub, the controller comprising a clock, the controller operably coupled to a recirculation pump and a drain pump, the controller configured (a) to cause the recirculation pump to supply liquid used during the wash cycle to the reuse tank, (b) to monitor via a clock a period of time that the liquid is within the reuse tank, and (c) when the period of time is greater than a predetermined period of time, (i) to cause a control valve in an outlet conduit to open and allow the liquid to flow from the reuse tank to a sump and (ii) to cause a drain pump to drain the liquid from the sump and out of the dishwasher.

A retrofit auxiliary device for distributing cleaning resources to a household cleaning appliance having a treating chamber is described wherein the device can connect to various household cleaning appliances of different makes and models and can learn the flow of water and detergent during various stages of operation and then perform the dispensing itself.

A dishwasher includes a case, injection arms, a sump including an injection flow path coupling portion, a washing pump for supplying washing water stored in the sump to the injection arms, and a switching valve including a flow path distributor for distributing washing water to injection arms. The flow path distributor defines distribution holes. When the flow path distributor is in a reference position, the distribution holes are positioned so that all of the injection arm supply holes are opened, and, when the flow path distributor is rotated by a first angle from a reference position, the distribution holes are positioned so that any one of the injection arm supply holes is opened. The injection flow path coupling portion includes a plurality of support ribs protruded toward the flow path distributor and including a support rib corresponding to at least one of the distribution holes.

The present disclosure relates to a dishwasher and a method of controlling the same. The dishwasher may determine an amount of foam in a wash space using a turbidity sensor measuring a turbidity value of wash water. Additionally, the dishwasher may perform a foam removal operation based on the amount of the foam in the wash space. In this case, the turbidity value measured by the turbidity sensor may be used. The foam removal operation may include a drainage operation, a water supply operation, and a wash operation that are consecutively performed, and may be performed in one or more of a pre-wash course, a main wash course, and a heating and rinsing course.
