A dishwashing apparatus has a grip with a water supply receptacle and a liquid detergent receptacle, and a working head with a plurality of portions circumferentially arranged about its axis and with a water outlet formed in one portion and a liquid detergent outlet formed in another portion.

A mildly alkaline enzymatic detergent cleaning composition adapted for use in automatic dishwashing machines comprising (a) an amylolytic enzyme, (b) sodium triphosphate, (c) sodium carbonate and/or borax, (d) sodium silicate, (e) a peroxy compound bleach, (f) a stabilizing agent, and optionally but preferably (g) a proteolytic enzyme and/or (h) a low- to non-foaming nonionic surfactant and/or (i) a fatty acid having chain length of about 12-18 carbon atoms, the amounts of components (b), (c) an...

The operational process includes a step in which water is let into a collecting sump (5) up to a static level (L) . The water is then sprayed onto the washload through appropriate spray means (8, 13) that are supplied by a pump (7) having a suction mouth (11) whose top portion is situated at a level (H). The water is sprayed in an intermittent manner through a sequence of alternating spray periods (T) and pause periods (Tp) during which the pressure of the water downstream of the pump (7) is at ...

Aqueous liquid dishwashing detergent compositions are prepared that exhibit improved detergency performance and foam stability over a range of water hardness levels. A preferred formulation incorporates a three component mixture: an anionic surfactant, a nonionic surfactant, and an amido amine oxide to provide a detergent having good detergency performance and foam stability over a range of water hardness levels. Another preferred formulation incorporates a three component mixture: an anionic su...

A waterproof dishwashing mitten is provided and consists of an inner pocket for receiving a hand of a person, a middle liner for protecting the inner pocket from moisture and keeping the hand dry, and outer pocket for washing the dishes, and elastic band sewn on the outer pocket to provide a wrist-hugging and enlargeable entrance to the inner pocket, a loop to hang up the mitten, a mesh net bag for retaining a soap therein and which can be placed through an elongated slot in the outer pocket tha...

A flexible dishwashing accessory having elongate flexible cords attached at their ends to attachment members which in turn attach the accessory to a rack such as is used for cleaning, rinsing, drying or storing eating or cooking utensils. The accessory is used by placing utensils in contact with at least one flexible cord such that the utensil stretches the cord to create a pressure on the utensil sufficient to hold it in place when subjected to jets of water or air such as are generated by dish...

A stable liquid automatic dishwashing compositions as well as a process for its preparation is disclosed. The composition is an aqueous thixotropic fluid possessing a yield point. The composition may include swellable clays, synthetic polymers, a specified amount of multivalent cations, builder salts, an alkaline source, a hypochlorite source, nonionic or anionic surfactants, and defoamers. The system containing clay, polymer, and ions thickens the composition to provide structure to suspend fin...

A combination dishwashing machine and oven is formed of an open-topped tank with a cover closing its opening, a heating element unit spaced vertically above the opening in the tank, and a vertically displaceable shell positionable between the cover and the heating element unit for laterally defining the oven space. A vertically arranged support column is associated with the tank and includes a lifting mechanism for displacing the shell downwardly into the tank from its position about the oven an...

A dishwashing apparatus has an air inlet conduit located in the bottom wall of the washing chamber. A forced air circulation apparatus is attached to a support bracket on the air inlet conduit from the outside of the washing chamber through a partial turn rotary motion. The air circulation apparatus is locked in this attached position by tightening a threaded fastener from within the washing chamber.

An automatic dishwashing composition which is in the form of a tablet generally comprises an alkali metal phosphate detergent builder salt, an alkali metal carbonate, a lubricant, a dialkali metal disilicate, a nonionic surfactant, a polymer containing sulfonic acid groups, a wax coated chlorine bleach compound, and optionally an anionic surfactant.
