  • Patent number: 10493387
    Abstract: In one embodiment, after a new filter unit (3) is installed in a treatment liquid supply apparatus, there is performed, before a solvent-containing treatment liquid is passed through the filter unit, a step of soaking the filter unit with a solvent for pretreatment and then discharging therefrom the solvent. The solubility of a material, constituting a filter part (31) of the filter unit, to the solvent is greater than the solubility of the material to the treatment liquid. This step makes it possible to remove a component, which may elute from the filter part into the treatment liquid to produce foreign matters (particles), before treatment liquid is passed through the filter unit.

    Abstract: Provided are a dish washing machine capable of effectively removing garbage which remains at the bottom of a washing tub and a filter and a method of controlling the same. When washing water is sprayed from a nozzle while a vane is positioned at a reference position during a drainage operation, since a deflection angle of the vane is bent back and the washing water is strongly sprayed toward a rear wall of a washing tub, the washing water may form a fast and strong water current over a bottom plate of the washing tub, and the fast and strong water current may remove garbage which remains at a filter while flowing over the bottom of the washing tub. Also, even when an excessive amount of garbage is accumulated at a filter at a top end of a sump and blocks the filter during a washing operation such as preliminary washing, main washing, etc., the filter is automatically washed using a small amount of water, thereby eliminating inconvenience of a user to directly separate and wash the filter.

  • Patent number: 9721815
    Abstract: In a substrate processing apparatus, chemical-solution processing is performed by supplying a chemical solution to the upper surface of a substrate in a state where a top plate is located at a first relative position. Also, cleaning processing is performed by supplying a cleaning liquid to the upper surface of the substrate in a state where the top plate is located at a second relative position closer to the substrate than the first relative position is. Moreover, dry processing is performed on the substrate by rotating the substrate in a state where the top plate is located at a third relative position closer to the substrate than the second relative position is. This allows a chemical atmosphere above the substrate to be efficiently removed during the cleaning processing. Consequently, the occurrence of particles due to the chemical atmosphere above the substrate can be suppressed during the dry processing.

  • Patent number: 9192280
    Abstract: Embodiments of the present invention relate to methods and systems for detecting and removing a clogging condition of a filter in a dishwasher. According to one embodiment, the method includes determining a normal water level or a normal rate of water level change for a wash cycle of the dishwasher and monitoring a water level or a rate of water level change during execution of the wash cycle. The method further includes detecting the clogging condition of the filter by detecting a deviation thereof. A current position of the wash cycle being executed may then be determined. The method further includes executing a remedial operation to facilitate removal of the clogging condition and determining if the clogging condition has been removed. Finally, the method includes resuming operation of the dishwasher at a wash cycle position based on the current position if the clogging condition has been removed.

  • Patent number: 9039843
    Abstract: The invention relates to a cleaning system for coffee machines, comprising a cleaning device for periodically cleaning the coffee- and/or milk-carrying components using a cleaning liquid, which contains cleaning agent in the form of balls or tablets dissolved therein, wherein the cleaning device is provided with a time- and/or product-cycle-dependent controller and a metering apparatus (1) for the cleaning agent (10) that interacts with the controller. Thus, it is possible to program the cleaning process in a customized manner according to the mode of operation and to carry out the cleaning process fully automatically according to the program. The metering of the cleaning agent (10) according to the program ensures an always optimal cleaning effect together with sparing use of cleaning agents. Simple and safe handling is achieved by using ball- or tablet-shaped cleaning agents.
