Abstract

HAIR DRYER INCLUDING A TUBULAR BOX, A RESISTOR, AND A MOTOR FAN UNIT SUITABLE TO CREATE IN THE BOX AN AIR CURRENT PASSING ON THE RESISTANCE. ACCORDING TO THE INVENTION, THE CASE INCLUDES A REAR TRUNK 30 AND A FRONT TRUNK 32 WHICH JOIN TO ONE ANOTHER BY ELASTIC SNAPPING; THE MOTOR-FAN UNIT AND THE RESISTOR 12 ARE MOUNTED ON THE REAR TRUNK 30; THE ANTERIOR TRUNCON 32 COMES TO STYLE THE RESISTOR 12 WHICH, AFTER THE ASSEMBLY OF THE TWO TRUNKS, IS THUS LOCATED INSIDE THE ANTERIOR TRUNCON 32. THE INVENTION IS APPLICABLE TO VERY LIGHT HAIRDRYERS HELD BY HAND.

Description

The invention relates to light hair dryers des-

  designed to be hand-held and, more specifically, to those who understand, in a tubular case, a

  heating element and a motor-cooling unit

  connected to a power supply cord,

  group being adapted to create the posterior end

  at the anterior end of said housing a current

of air passing on the resistance.

  The object of the invention is to propose a hair dryer

  of this kind which is of simple realization and of

  fast, and therefore particularly well adapted to

mass production.

  In a hair dryer according to the invention, the housing

  comprises a posterior tubular section and a section

  tubular anterior section assembled in the extension

  from each other by means of el-

  tick, and the fan unit is arranged in

  the posterior segment while the resistance is

  on a support engaged in a seat on the said

  posterior section and extends in said anterior section.

  Thanks to this arrangement, we can perform first

  on the rear section the assembly of all

  Electrical elements: fan assembly, resistance, 2- cord Then, to complete the casing of the device, put the anterior section on the support of the resistance until the assembly

  mutuel of the two sections by snap elastic.

  The features and advantages of the invention

  will come out from the following description,

  for example, with reference to the accompanying drawings in which Figure 1 is a longitudinal section of a hair dryer according to the invention i Figure 2 represents the hair dryer seen from the rear;

  The hair dryer shown comprises, in a cylindrical tubular housing 10, a heating resistor

  12 and a motor-fan unit 14 consisting of a motor

  16 and a fan 18 The motoventilator group

  14 is adapted to create from the rear end to the front end 22 of the housing a stream of air passing over the resistor 12. These ends 20 and 22 respectively carry a cold air intake grille 24 and a cooling grid. hot air outlet 26 The resistor 12 and the group 14 are connected to a cord

power supply 28.

  According to the invention, the casing 10 is made in two parts, namely a posterior tubular section 30 and an anterior tubular section 32, which are assembled in the extension of one another by resilient snap-fastening devices comprising, in particular, pins 34 carried by the inner face of the section

  posterior 30 and engaged in lights 36 practically

  in the wall of the anterior section 32 The group

  The motor-fan 14 is arranged in the section

  30, while the resistor 12 is mounted on a support 38 engaged in a seat 40 formed by two spaced extensions 42, the posterior portion La

  resistance-12 thus extends inside the

previous issue 32.

  The power cord 28 enters the housing through a passage 44 left between the sections 30 and 32 of this housing. Part 46 of this cord, close to the passage 44, is applied longitudinally against the external face of the rear section 30 and is housed for this purpose in a groove 48 formed on this outer face and closed by a hood 50 The edges 52

  of this hood 50 are engaged with the longitudinal edges

  dinaux 54 of the gutter (see fig 7), this cover pre-

  feeling for this purpose a shaped cross-section

  of U and being slidably mounted longitudinally-

  4. The front end to the rear according to the arrow F of Figures 4 and 6 The front end 55 of the cover comprises lugs 56 which, during assembly of the anterior section 32 with the rear section 30 (arrow G in Figure 4), hang on

  bosses 58 formed on the inner face of the section

  prior art 32, the anterior end 55 of this

  pot 50 penetrating for this purpose in the anterior section

  32 through the passageway 44 The legs 56 then form

  if part of the elastic snap-in devices

  rant assembly of the two sections of the box.

  As seen in Figures 6 and 8, the edges

  longitudinal lines 54 of the channel 48 comprise each

  one flexible wing 60 So the cap 50, when

  sliding installation (arrow F), as-

  sure of a rapprochement of the two wings 60 and a clamp

  part 46 of the cord 28 housed in the droplet

  48 The hood 50 and the trough 48 together constitute a clean cable holder to retain the

  cord 28 against slipping relative to the housing

  This clamping effect is even better

  because the flexible wings 60 are respectively

  two bosses 62 facing one another,

  as well as streaks 64 (FIG. 8) which come into

with the cord.

  As illustrated in Figure 4, during manufacture

  of the apparatus, the first step is to carry out the

  interior 30 assembly of all the electrical elements: fan assembly 14, resistance 12 on its

  support 38, and cord 28 retained by the cover of ser-

  Then, to complete the housing of the apparatus, the front section 32 is threaded onto the support 38

  resistance (arrow G), until the assembly is

  between the two sections 30 and 32 by means of

  resilient stage of the lugs 34 in the lights 36.

  During this movement, the front end 55 of the body

  pot 50 penetrates the former section 32 by the

  passage 44, and the legs 56 also come into play.

  elastically snap on the bosses 58 (FIG. 5), the cable-grip cover 50 thus plays the role of a worm.

  which reinforces the assembly of the two parts of the bot-

  tier. In the variant embodiment shown in

  9, the cover 50 carries an appendix 66 which forms a
