A washing operation and a drying operation are performed while a basket which is located inside a washing tub and accommodates dishes reciprocates in a vertical direction of a washing tub due to a driving device. The basket reciprocates in order to pass through an injection nozzle which injects washing water and an air nozzle which injects air to perform the washing operation while passing through the injection nozzle and to perform the drying operation while passing through the air nozzle. Through this, a small amount of dishes may be washed and dried in a short time and the dishes may be washed using a small amount of water and energy.

A sink-type washing machine includes a case, a drain board, a water pump and a rotary spray arm; the case includes a sink body and a cover plate; the sink body has a recess which forms a drain region, the water pump is inside the drain region, the drain board covers the drain region, the rotary spray arm is above the drain board, water outlets being in communication with the flow channel in the water pump so that water in the drain region can be sprayed into the washing space and above the drain region. A drain board covers the drain region and a water pump is disposed inside the drain region, the water pump is isolated from the washing region by the drain board, so that the water flowing back to the water pump is firstly filtered by the drain board.

The present invention is a drinking straw washing machine with a washing region, a sanitizing region, a straw retaining track, and a motor assembly. The washing region comprises a washing cogwheel rotatably positioned therein that receives straws via the straw retaining track. The washing cogwheel and sanitizing cogwheel are oriented parallel to the straw retaining track. The motor assembly is mechanically coupled to the washing cogwheel and thereby rotates the washing cogwheel to guide straws along the straw retaining track and through a cleaning solution included in the wash region. the sanitizing region comprises a sanitizing cogwheel rotatably positioned therein that receive straws from the washing region via the straw retaining track. The motor assembly is mechanically coupled to the sanitizing cogwheel and thereby rotates the sanitizing cogwheel to guide straws along the straw retaining track, through a sanitizing solution in the sanitizing region, and out of the sanitizing region.

A portable handheld submersible ultrasonic cleaning device has a generally elongate body defining proximal and distal ends, a power supply and an ultrasonic transducer powered thereby, wherein the distal end exposes the ultrasonic transducer to agitate surrounding water when the base is submerged in the water use. A propeller device comprising a propeller may force the water across the ultrasonic transducer. When cleaning, the device may be held with the distal end thereof submerged for enhanced cleaning and removing surface contaminants such as dust, dirt, oil, pigments, bacteria and the like. The device may be stood upright upon the base on the floor of a container for hands-free application of ultrasound whilst cleaning.

A dishwasher system which comprises a washing unit. The washing unit comprises an outer housing and an inner housing enclosing a washing chamber and a door for closing a front opening of the washing chamber. The washing system also comprises a control unit for controlling the dishwashing operation.

An apparatus and method for washing and drying objects includes a rotating washing fluid sprayer having several nozzles to direct washing fluid, e.g., water, at an object being washed in a chamber. A drying fluid is directed at the object in the chamber to dry the object. The drying fluid, e.g., air, is directed in a spiral pattern against the object to urge washing liquid away from the object to dry the object and to push the drying liquid away from edges of the object. The air may be directed at the object simultaneously with the water to increase the energy with which the water impinges on the object and to urge dirt from the object being washed.

A personal dishwasher washes and dries a dish that is manually or mechanically moved through a dishwasher chamber or is manually placed in and manually removed from the chamber. Pressurized water, possibly containing soap, wetting agent, etc., may be added to the wash water. Steam may be used to for cleaning and/or disinfecting. Ultraviolet light may be used for disinfecting. The dishwasher chamber may be enlarged to pass larger dishes, bowls, glassware, etc. for washing. A method of washing dishes, comprising inserting a dish manually into a dishwasher, passing the dish through the dishwasher, and withdrawing the dish. A method of washing a dish, comprising inserting a single dish into a dishwasher, directing fluid under pressure at the dish, directing air flow at the dish, and withdrawing the dish.

An apparatus and a method of washing (or pre-washing) silverware/flatware, or one or more other objects/parts is provided. The apparatus and method utilizes a fluid-push/pull pumping system and method in which generally an entire volume of fluid is pushed or pulled through a cavity of a housing in which the silverware/flatware or other objects/parts are located. The housing is configured to hold a mass of silverware or other item(s) within the cavity. The pumping system is configured to pump generally an entire volume of fluid out of the cavity, and to direct the pumped fluid back into the cavity to create a generally continuous flow of generally an entire volume of fluid through the cavity, thereby causing the fluid to flow through the mass of silverware or other item(s).

A heating system for heating a target fluid may include an intermediate liquid circulation path for holding an intermediate liquid and a target fluid flow path for conveying the target fluid, where the target fluid flow path and the circulation path are separate from one another but thermally communicate with one another via a heat exchanger. The intermediate liquid may be heated by a heater and circulated in the intermediate liquid circulation path by a pump. A ratio of the maximum heat output of the heater to the volume of the intermediate liquid circulation path may be at least about 5 Watts/cm.sup.3. The thermal mass of the intermediate liquid may be 0.3 times the thermal mass of the target fluid or less. The heating system may be utilized in a washing appliance such as a dishwasher, where the target fluid is the wash water used in such appliance.
