A hair cooling and dehumidification apparatus includes a wearable headgear. The wearable headgear includes an outer layer, an insert layer, and an inner layer. The outer layer includes a supply port. The supply port is in fluid communication with a high-pressure storage tank via a vortex tube. The insert layer, detachably attached to the outer layer, includes a network of ducts and detachable insert elements. The ducts are in fluid communication with the supply port to receive a cooling gas from the vortex tube and distribute the cooling gas to the hair. The detachable insert elements are detachably attached to the insert layer via fasteners. The detachable insert elements, spaced apart to accommodate the network of ducts there between, comprise desiccant materials embedded within for absorbing moisture. The inner layer is proximal to the hair of the user to transfer the cooling gas to the hair.

In a hair styling device (20) having a two-dimensional array (21) of elements to bring hair at a styling temperature, the elements produce optical radiation energy. The elements may include one or more LEDs, and preferably a plurality of LEDs, in which case the LEDS are driven in clusters that may be of mutually different shapes and sizes. The hair styling device (20) further comprises sensors to obtain an areal light absorption measurement opposed to the two-dimensional array of elements, and a control unit for individually controlling the elements in dependence of the measurement. The sensors may be arranged for measuring an areal light density profile of a whole treatment area. The hair styling device may radiate hair from two sides, both of which includes an areal light absorption measurement. The sensors may include LEDs that do not produce light.

A control device (1) for a washroom facility that includes an actuator (2); a sensor (4) configured to detect the presence of a user in the proximity of the sensor (4); and a control circuit (6) receiving, as input, signals from the sensor (4) and configured to control the actuator (2). The sensor (4) includes an emitter (10) configured to emit an infrared signal; and a receiver (8) configured to detect the infrared signal emitted by the emitter (10). The invention also provides a washroom facility, a substance dispenser, and a hair dryer or hand dryer, including such a control device (1).

A liquid spraying device including a tank configured to store liquid, a spraying device including a discharger configured to discharge the liquid in a form of a mist, a first flow path forming part disposed between the tank and the discharger and forms a first flow path of the liquid, a pump provided midway of the first flow path, and feeds the liquid from the tank toward the discharger, and a second flow path forming part configured to form a second flow path that branches off from the first flow path at a branching position between the pump and the discharger, and returns to tank. The first flow path forming part includes a small sectional-area part between the branching position of the first flow path and the discharger, the small sectional-area part forming a flow path having a sectional area smaller than a sectional area of the second flow path.

An attachment for a hand held appliance comprising a body having a first wall; a second wall; and a slot formed along at least part of the length of the attachment, wherein the slot is defined on a first side by a surface of the first wall and on a second side by a surface of the second wall. The first wall may be generally tubular. The surface of the second wall may be substantially linear. The second wall may extend out from the first wall. The second wall may be moveable or rotatable relative to the first wall. The second wall may be generally triangular. The second wall may have a first indexed position defining a first slot position. The second wall may have a second indexed position defining a second slot position. An indexed position may be defined by a detent mechanism.

A hands-free dryer allows for drying of a target while permitting the hands of a user to not be controlling the operation of the hands-free dryer. The hands-free dryer includes a blower for providing air flow, an orientation system allowing the blower to be adjustably oriented at an angle. There is a semi-rigid flexible hose connected to the blower that retains its configuration without the user having to maintain the configuration. Also, there is a support system that provides support for the hands-free dryer while worn by the user.
