A capsule includes an upper body portion and a lower body portion that is coupled to the upper body portion. The lower body portion includes a lower wall that defines a lower opening. The lower body portion and the upper body portion together define an internal cavity. At least one of the upper body portion or the lower body portion includes a plurality of grooves spaced at intervals along a circumferential direction with respect to a central axis of the capsule. The plurality of grooves extends at an angle in a partially axial direction and a partially circumferential direction.

A foam generating device for a high-pressure water gun has a supporting body defining part of a conduit, which extends along an axis and has a mixing chamber communicating with a lower inlet, and subject, in use, to a vacuum to aspirate a liquid from said lower inlet; the device has a first sleeve which is fitted around one end of the supporting body, is axially fixed, is rotatable and is provided with an end portion carrying a nozzle; such a nozzle defines the outlet of the conduit and is adjustable so as to vary the outgoing flow type between a fan-like jet and a solid stream jet; the device has, in addition, a second sleeve which is coupled to the first sleeve in a fixed axial position and in a rotatable manner and is provided with cams to adjust the nozzle in response to a rotation of the second sleeve with respect to the first sleeve.

An automated soap mixing and dispensing apparatus is configured to automatically melt a quantity of solid soap for mixture with a liquid carrier to provide a source of liquid soap solution. The apparatus includes a fluid reservoir configured to initially contain liquid carrier. A grill with apertures supports the solid soap. A heating element heats the solid soap to a molten state and the molten soap drips through the apertures into the liquid carrier. A rotary mixing unit mixes the molten soap with the liquid carrier to form the liquid soap solution. The dispensing apparatus may then be utilized to dispense the liquid soap for cleaning activities, such as personal hygiene. The apparatus improves the carbon footprint for hygiene activities by eliminating the requirement for plastic containers containing premixed liquid soap solutions.

A washing machine includes a cabinet; an outer basket in the cabinet and configured to contain wash water; an inner basket in the outer basket and configured to accommodate laundry; a water supply valve unit in the cabinet and connected to an external water supply source to receive wash water; a cabinet cover on an upper side of the cabinet and having an input hole for the laundry; and a micro-bubble generator configured to receive wash water from the water supply valve unit, generate micro-bubbles, and supply the micro-bubbles to a washing space. The micro-bubble generator includes a nozzle unit at or near the input hole and configured to generate micro-bubbles by receive wash water in which gas is dissolved or mixed and discharge wash water having the micro-bubbles therein into the inner basket after the micro-bubbles are generated.

Disclosed is a method for the preparation and supply of an enzyme-containing detergent formulation, the method comprising the steps of: a transferring from a plurality of feed sources (3a to 3f) the ingredients required for forming a batch of the detergent formulation into a mixing vessel (25), b mixing the ingredients to form the batch, c discharging the batch from the mixing vessel, d by pumping supplying at least a part of the batch to at least one treatment device (42), wherein at least one feed source is comprising an enzyme-containing concentrate, wherein the preparation is performed on-site with the treatment device, and wherein the amounts supplied of the batch and of the enzyme concentrate as part of the batch are determined by weight. Also disclosed is an apparatus (41) for on-site with the treatment devices (42) preparing and supplying the detergent formulation.

A foam generator, in particular for a motor vehicle washing installation, includes a foam generation chamber having at least one inlet for water, surfactant and gas, in particular compressed gas, and one outlet for foam, and contains a fluid-permeable bed of loose particles. The bed fills the foam generation chamber sufficiently to prevent fluidization of the bed.
