Description

The present invention relates to a bottle heating apparatus

  containing liquids such as hair treatment liquids at a temperature of

in the range of 35 to 45 C.

  This device is more particularly intended

at hair salons.

  When washing their clients' hair, hairdressers use hot water at a temperature of

  of the order of 40 ° C., that is to say essentially at the temperature

  body, but at the same time pour a shampoo which is at room temperature, that is to say about 19 C; gold,

  this difference in temperature provides a

  pleasant on the scalp.

  To remedy this problem and improve the con-

  With their clientele, hairdressers have become accustomed to using empirical means consisting, for example, of placing the bottle of shampoo on a radiator

  or in a double boiler, pour it over your hand for

  heat before application or spray it on

  the heads of their customers, which is particularly incom-

fashion.

  An essentially similar problem is encountered

  be when the hairdresser technician performs a perm.

  Indeed, during a first step, he then applies the product to perm on the hair to be treated previously wound on rollers; it then covers the hair thus treated with a plastic cap so as to increase its temperature and to catalyze the reaction and leaves the product to act permanently for approximately

15 minutes.

  The second step in this process is to rinse

  hair treated with hot water (around 40 C) and at

  apply a fixing product to it, which is also

ambient temperature.

  It should be noted that in this case, the temperature contrast is even more unpleasant for the customer than

  in the case of a shampoo, since his scalp has previously

  have been exposed to a higher temperature over the long term

vee and is therefore more sensitive.

  To remedy this problem and improve the con-

  strong of their clientele, the hairdressers have, there again, resort to empirical means such as the preliminary heating of the fixing product in a water bath or the mixture of this with

lukewarm water.

  We have never proposed simple and practical means to solve the above problems by removing the unpleasant feeling that can be felt by customers of hair salons in their leather

  hairy due to temperature differences that may exist

  ter between different treatment products.

  The object of the present invention is to fill

  this shortcoming by offering a bou-

  bees, generally made of glass or plastic, containing liquids and in particular hair treatment liquids at a temperature of the order of 35 to C. This apparatus is characterized in that it is constituted by a resting box on feet and delimiting at its internal part a heating enclosure of one or

several bottles.

  According to the invention, this box is closed, on the one hand, laterally by a thermally insulating envelope and, on the other hand, at its lower part by a grid

  air access and at its upper part by a partition

  drilled lid forming the introduction into

  the heating chamber of the bottle or bottles to be heated.

  The box is furthermore equipped in its part

  dull a grid for receiving the bottle (s)

  heat or bottle holder grid, as well as at least one

  heating element located below the installation grid

  bottles when the appliance rests on its feet and cooperates

  rant with electricity supply devices.

  It should be noted that this device is more particu-

  intended for hairdressing salons but could be used in another field, without going beyond the framework

of the invention.

  In order for the heating chamber to be kept at the optimum temperature, it is necessary that it is as airtight as possible at its upper part and therefore that the dimensions of the perforations of the

  partition forming a cover correspond to the section of the bou-

  seals to be heated, however providing sufficient clearance to allow them to expand following

the increase in temperature.

  It is also necessary that all bou-

  pins to be heated are constantly in place on the bottle rack and are immediately reintroduced into the heating enclosure by the hairdresser after each

use.

  Taking into account the aforementioned configuration, the ambient air enters the heating enclosure through its lower part, through the air access grille and

  is then heated by the heating element, which pro-

  evokes its displacement upwards around the boulevard (s)

  to be reheated due to the variation of its mass

  volume following the increase in its temperature.

  The relative tightness of the partition forming

  circle, linked to the presence of the bottles in the perforations

  tion of the latter, makes it possible to confine the hot air to this level so as to obtain the desired reheating of the treatment liquids. It should be noted that the device conforms to

  the invention may, depending on the case, have a rectangular section

  circular or circular and is generally suitable for re-

  ception of one to three bottles which can if necessary be made up of graduated containers replacing the bottles

  usual shampoo or fixer.

  According to another characteristic of the invention,

  the lateral envelope is constituted by a central block

  metal, preferably stainless steel, on which is

  fixed for example clipped a piece of external coating no-

  so much plastic so as to define a double

  wall which may, if necessary, contain thermal insulation

  than. It is necessary that the inner wall and the pa-

  external king constituting this double wall is sufficiently spaced, this to guarantee a good thermal insulation of

  the heating chamber, but also to allow the lo-

  management of the electricity supply members of the resistance

  heating element (cables, connection devices, ...).

  According to the invention, the perforated partition forming a cover is also preferably constituted by a double metal wall, preferably made of stainless steel.

  designed to guarantee satisfactory thermal insulation

  doing at the top of the heating enclosure and trapping the air heated by the resistance around the or

bottles to warm up.

  According to another characteristic of the invention, the resistance is a fin resistance fixed to the central block of the lateral envelope and electrically insulated by

compared to this one.

  This resistor is preferably equipped with an armored body allowing it to withstand splashing water. To guarantee optimal thermal insulation of the heating enclosure, the bottle-laying grid and the central block of the side envelope are also electrically

  isolated from each other.

  According to another characteristic of the invention, the elements for supplying electricity to the heating resistor include a switch which can in particular be actuated by the hairdresser each morning to start the

  heating of the heating chamber.

  These members are also preferably equipped with a variator making it possible to adjust the electric power dissipated by the heating resistor, and consequently, the

  temperature of the heating chamber; it can, in particular

  link, be expected to speed up the heating process at the start of the day so that the temperature of the heating chamber quickly reaches the desired temperature and that the first customers can benefit from shampoos or

  fixers previously warmed.

  One can also advantageously provide

  to equip the electricity supply organs of the

  heating element of a thermostat fitted with a bimetallic strip capable of cutting off the electricity supply when the

  heating chamber temperature exceeds a pre-

  determined adjustable, so as to exclude any risk of

  heating the process liquids to a temperature

  before causing scalp burns, or to avoid any deterioration of these products following

  raising their temperature to too high a level.

  According to another characteristic of the invention, the lateral envelope is equipped with wall fixing lugs

of the device.

  The apparatus according to the invention can, of course,

  stretched, simply placed on a horizontal surface or

  still embedded in the cabinet of a shampoo tank.

  The characteristics of the device for heating bottles containing liquids which is the subject of the invention will be described in more detail with reference to

  attached drawing which is a representative diagram of this apparatus

reil.

  According to the figure, the device is intended for re-

  heating of hair treatment liquids contained in three bottles B1, B2 and B3; this number has been chosen only as an example and is, of course, in no way limiting

of the invention.

  This device consists of a 1 repository

  on four feet 2 and delimiting, on its internal part,

  a heating chamber 3 for bottles B1, B2 and B3.

  According to the figure, the box 1 is closed, of a

  share, laterally by a cylindrical envelope 4 thermal-

  insulating and, on the other hand at its lower part, by an air access grid 5 and at its upper part by a partition 6 forming a cover provided with three perforations 17; these perforations allow the introduction of bottles B1, B2 and B3 into the enclosure 3 and have a shape and dimensions corresponding to the section thereof, apart from the expansion gap.

  The box 1 is also equipped in its part

  internal tie of a bottle-laying grid 7 as well as a fin resistor 8 disposed below the bottle-laying grid 7 and cooperating with members

electricity supply 9.

  According to the figure, the side envelope 4 is cons-

  with a double wall 101, 102 sandwiching a thermal insulator 11 and enclosing the cables and connections

  electrical components of the power supply 9.

  This double wall is more precisely formed by a central block of stainless steel 101 on which is

  fixed a piece of plastic covering 102.

  The fin resistance 8 as well as the bottle holder grid 7 are fixed on the internal wall 101 of

  the casing 4 being electrically isolated from this wall.

  According to the figure, the perforated partition forming a

  circle 6 is also constituted by a double wall

  size 121, 122 ensuring good thermal insulation of the heating chamber 3 around the bottles

B1, B2 and B3.

  According to the figure, the ambient air enters

  the heating chamber 3 through its lower part, through

  towards the air access grid 5, according to the arrows a and is heated at the level of the fin resistance 8; following its temperature increase, it then moves upwards through the bottle-laying grid 7 and is blocked around the bottles B1, B2 and B3 taking into account the relative tightness of the partition forming the cover 6 ; the treatment liquid contained in bottles B1, B2 and

  B3 can thus be reheated to the desired temperature.

  Furthermore, and according to the figure, the organs 9 for supplying electricity to the fin resistor 8 comprise a switch 13, a variator 14 making it possible to adjust the electric power dissipated by the fin resistor 8 as well as a bimetallic strip 15 capable of cut off the electricity supply when the temperature in

  enclosure 3 exceeds a preset predetermined threshold value

  corn. The heating device, according to the invention, can contain other elements such as for example wall fixing lugs not shown.
