AI Technical Summary

Benefits of technology

The invention is a device that reduces turbulence and pressure loss in a fluid flow path, by using several arms that are symmetrically arranged across the path. The arms extend symmetrically from a central hub and are equally spaced around it. The device also includes a PCB that is located between the handle and the upstream end of the device. This setup helps to minimize the interaction between the fluid and the PCB, which can help to reduce noise and improve efficiency. Overall, the device improves the performance and stability of fluid flow systems.

Problems solved by technology

The motor is susceptible to damage from foreign objects such as dirt or hair so conventionally a filter is provided at the fluid intake end of the blower.

Embodiment Construction

[0105]FIG. 1 shows a hairdryer 10 with a handle 20 and a body 30. The handle has a first end 22 which is connected to the body 30 and a second end 24 distal from the body 30 and which includes a primary inlet 40. Power is supplied to the hairdryer 10 via a cable 50. At a distal end of the cable 50 from the hairdryer 10 a plug (not shown) is provided, the plug may provide electrical connection to mains power or to a battery pack for example.

[0106]The body 30 has a first end 32 and a second end 34 and can be considered to have two parts. A first part 36 which extends from the first end 32 which is tubular and of a generally consistent diameter and a second part 38 which extends from the second end 34 to join the first part 36. The second part 38 is cone shaped and varies in diameter along its length from the diameter of the first part 36 of the body 30 to a smaller diameter at the second end 34 of the body.

[0107]The handle 20 has an outer wall 200 which extends from the body 30 to a d...

Abstract

A device for distributing at least one wire within a housing, comprising a central hub and at least one arm extending from the central hub towards the housing and wherein the at least one arm houses the at least one wire. The housing may be a tube having a larger diameter than the central hub. The at least one arm may comprise a pair of arms. The pair of arms may describe a Y shape. The device may be formed from a first part and a second part that may both provide a portion of the at least one arm and may both provide a portion of the hub. Also disclosed is a hand held appliance comprising a tube defining a fluid flow path from a fluid inlet into the tube to a fluid outlet from the tube and a device for distributing at least one wire to the tube.

Description

REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of United Kingdom Application No. 1321809.4, filed Dec. 10, 2013, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates to a hand held appliance and in particular a hair care appliance such as a hairdryer.BACKGROUND OF THE INVENTION[0003]Generally, a motor and fan are provided which draw fluid into a body; the fluid may be heated prior to exiting the body. The motor is susceptible to damage from foreign objects such as dirt or hair so conventionally a filter is provided at the fluid intake end of the blower. Conventionally such appliances are provided with a nozzle which can be attached and detached from the appliance and changes the shape and velocity of fluid flow that exits the appliance. Such nozzles can be used to focus the outflow of the appliance or to diffuse the outflow depending on the requirements of the user at that time.[0004]The fan...
