A stamped resistive element for use in electrical equipment, manufacturing process of stamped resistive element and apparatus equipped with stamped resistive element are provided. The stamped resistive element is produced from a stamping process and is intended to be used in replacement of conventional helical electrical resistances, whether in hair dryers and similar equipment or in other types of heating equipment. The stamped resistive element is produced as a blank from a metal sheet presenting a known resistive coefficient.

An attachment for a handheld appliance, the attachment having a first end for connection to the appliance and a second end, a first wall extending from the first end towards the second end and defining a fluid flow path through the attachment, a second wall extending from the second end towards the first end about the first wall and defining a second fluid flow path extending between the first wall and the second wall. The first end of the appliance may be substantially circular. The fluid flow path may have a fluid inlet that may be annular at the first end. The fluid inlet may be defined by the first wall and an inner wall extending around and at least partially along the first wall. The inner wall may be substantially equidistant from the first wall around the fluid inlet. A hair care appliance comprises such as attachment.

The invention relates to a hot-air fan including a fan device for generating an air flow, a heating device for heating the air flow, and a control unit connected to the fan device and to the heating device. In this process, the control unit is designed to control the fan device in such a manner that, when the heating device is switched on, the fan device generates a starting air flow that is reduced to an operating air flow. The invention also relates to a method for operating the hot-air fan, including the steps of switching on the heating device and generating a starting air flow that is reduced to an operating air flow.

A battery operated hair dryer includes a battery management and control module to control how to efficiently dry a user's hair while maintaining the health and charge of the battery.

Provided are thermal insulation components, the thermal insulation component extending in the direction of a major axis and the thermal insulation component comprising: an inner wall, the inner wall defining a lumen therein, the lumen having a centerline; an outer wall, the outer wall encircling the inner wall, the outer wall having a plurality of corrugations, the inner wall and the outer wall defining an insulating space therebetween, the insulating space optionally being evacuated; and at least one engagement feature configured to secure the component to an outlet, the engagement feature being arranged such that a line extending radially outward from the centerline of the lumen passes through the engagement feature without passing through the insulating space. Also provided are related methods.

A snow, ice and debris removal device is disclosed. The multipurpose device includes a handle, a cylindrically-shaped forced air blowing system and a plurality of controls. The cylindrical shaped forced air blowing system features a front opening for expelling cool or heated air, which is adjustable via a switch to suit the application for which the device is being used. The forced air blowing system comprises an internal induction heating/cooling coil that heats or cools the air expelled through the system. When the switch is set to hot air mode, the device expels a stream of heated air which the user can easily direct at snow and ice accumulations on, for example, a sidewalk, driveway, parked vehicle, etc. or to dry a surface. Alternatively, when the cool air mode is selected, the device expels a stream of cool air that the user can use to displace leaves and other debris.

The invention relates to an electrical, pistol-like handheld tool. The handheld tool includes a tool body for electrically activated machining of a workpiece, a grip part connected to the tool body at an angle thereto, an actuation device for manually activating and/or deactivating the handheld tool, which actuation device is arranged on the tool body or the grip part, and an unlocking device for manually unlocking and/or locking the actuation device. The unlocking device is arranged on the tool body or the grip part such that unlocking is effected by the handheld tool being supported in stable equilibrium on one of the fingers of a user's hand when the grip part is gripped by a user.

A heater including a ceramic heater element and ceramic heat sink whereby the ceramic heater element and the ceramic heat sink are both formed from a plurality of layers of tape cast ceramic material. The ceramic heater element may be generally planar and extends within a first plane. The ceramic heat sink may extend in a second plane which is orthogonal to the first plane. The ceramic heat sink may include a plurality of fins which may be discrete. The layers of the ceramic heater element may be orientated orthogonal to the layers of the ceramic heat sink. The ceramic heater element may comprise a conductive track which may be surface mounted to a distal side of the ceramic heater element than the ceramic heat sink or embedded within the ceramic heater element.

A battery operated hair dryer includes a battery management and control module to control how to efficiently dry a user's hair while maintaining the health and charge of the battery.

A heater comprising a ceramic heater element and at least two fins for dissipating heat from the ceramic heater element, wherein the ceramic heater element extends along a plane in one dimension and the at least two fins extend away from the plane, and wherein the at least two fins are connected to the ceramic heater element via discrete connecting portions.
