Definitions
- a hair curler heater has a thermostatically controlled electrically heated support plate provided with upstanding short projections each of which cooperates with a complementary depression in the bottom of a plastic coated hair curler.
- the curlers are filled with a heat storing substance and have a central core of high heat conductivity material.
- a heat insulating diaphragm is spaced above the projections and has holes so that curlers may rest on the projections.
- a transparent cover is provided over the plate. The cover controls an electric heater switch and signal lamps are provided to indicate operation.
- This invention relates to hair curler heaters.
- British patent specification No. 499,904 of 1936 discloses a hair curler heater comprising a plurality of rods adapted to transmit heat, on which the hair curlers are slipped and heated from the inside.
- the rods extend at right angles beyond a hollow or solid conductive support to which heat is supplied.
- British patent specification No. 419,043 of 1934 discloses heating hair curlers from the inside by placing them on electrically heated rods which are in contact with a metallic inner liner of the hair curler.
- the liner is hollow and filled with a heat retaining substance.
- British patent specification No. 581,101 of 1944 discloses slipping hair curlers for heating on rods carried by a plate incorporating a heating resistor controlled by a thermostat.
- this invention provides an apparatus for heating hair curlers, of the type comprising a plate-shaped conductive support to which heat is supplied and a plurality of heat conductive elements extending at right angles to the said support, each adapted to reach into a hair curler for transmitting heat thereto, wherein the heat conductive elements exend in height from the support a distance equalling a small fraction of the height of the hair curlers.
- Each hair curler comprises a metallic casing having a bottom portion shaped to interfit with one of the heat conductive elements, and a coating on the outer surface of the easing leaves the bottom portion exposed.
- the apparatus is also provided with a heat insulating partition superposed in a parallel relationship to the plate-shaped conductive support from which it is spaced a distance substantially exceeding the height of the heat conducting elements, the partition having openings coaxial with the heat conductive elements, the openings being of a size such as to allow the hair curlers to extend therethrough.
- FIGURE 1 is a perspective view of an apparatus for heating hair curlers according to this invention
- FIGURE 2 is a cross sectional view taken on line IIII of FIGURE 1;
- FIGURE 3 is an enlarged detailed view of FIGURE 2.
- FIGURES 4 and 5 are two enlarged sectional views showing two different embodiments of the base plate.
- a casing 1 molded of insulating plastic material rests on studs 7 and has a rear wall 2 and two side walls 3 decreasing in height towards a front wall.
- the rear wall 2 of the casing 1 has a transparent cover 4 articulated thereto by a hinge 5 which incorporates a microswitch 6.
- the casing 1 encloses a heat conductive support comprising a metal plate 8 incorporating a heating resistor 9 connectable to an electric power source and controlled by a thermostat 10 adapted to cut off the supply of current, as a predetermined temperature is reached.
- the microswitch 6 is placed in series in the supply circuit for the resistor 8 and is connected to the hinge 5 for the cover plate to allow electric current to flow to the heating plate 9 only when the cover plate is fully open, as shown in dash lines in FIGURE 2, and to cut off the supply circuit on closure of the cover plate.
- the heating plate 8 is provided on its top face with heat conductive elements in the form of conductor elements or projections 11 engaging hair curlers 13.
- the heat conductive projections 11 have their top portion of frusto-conical shape 12, see FIG. 3, for assisting in centering and retaining the hair curlers.
- the elements 11 extend in height beyond the plate 8 by an extent equalling a small fraction of the height of the hair curlers 13.
- the height of the elements 11 conveniently ranges be tween and of the height of the hair curlers 13.
- Each hair curler 13 includes a metal casing 14, having a bottom 15 which is formed with a frusto-conical recess 16 for interfitting with the frusto-conical ends 12 of each projection 11.
- An inner hollow space 18 in the metal casing 14 contains a heat storing substance 10, such as water or a water-wax mixture.
- a core 17 of a material of high heat conductivity may be positioned in the central portion of the casing 14 and extends axially upwardly within the casing from its bottom 15.
- the core generally may comprise a copper cylinder welded to the middle of the bottom 15.
- the outer surface of the metal casing 14 is provided with a coating 20 of plastic, such as polyamide resin, provided .at the middle of the bottom 15 with an opening 21 to allow the bottom 15 to directly contact and fit on one of the heat conductive elements 11 on the heating plate 8.
- a coating 20 of plastic such as polyamide resin
- the copper cylinder 17 accelerates transmission of heat to the heat storing substance 19; however, the cylinder 17 is not essential, for it was found, in actual use that a satisfactory transmission of heat already results from the interfit of the members 11, 15.
- a heat insulating diaphragm 22 is arranged over the heating plate 8 at a substantially higher level than the conductive elements 11 and is formed with a plurality of through holes 23 coaxial with the elements 11 through which the hair curlers extend. This avoids any direct contact of the users hands with the hot surfaces of the plate 8 and elements 11, preventing scorching.
- the diaphragm 22 is provided on its forward edge with an inclined portion 24 having arranged thereon two indicating lamp lights 25, 26, the lamp 25 indicating that the electric resistor is energized and the apparatus is operating, the lamp 26 being connected with the thermostat 1 and providing an intermittent light signal when the thermostat has cut-off the electric circuit of the resistor 9 as the predetermined temperature for heating the hair curlers is reached.
- the elements 11 extending from the heating plate 8 can be formed in various manners.
- a projecting element 11a is obtained by punching the plate 8.
- an element 11b is made as a separate part having a mushroom shaped head 27 and a cylindrical stem 28 be secured to the plate 8.
- each hair curler comprising :a metal casing having a bottom portion shaped to interfit with one of the heat conductive elements, and having a heat insulating plastic coating on the outer surface of the casing except the shaped bottom portion, and a heat insulating diaphragm in a parallel spaced relationship to the conductive plate-shaped support, the diaphragm being spaced from the conductive plate-shaped support a distance exceeding the height of the conductive elements but substantially less than the length of the hair curlers, the diaphragm including openings coaxial with the said conductive elements, the openings being of a suitable size for the hair curlers
- Apparatus for heating hair curlers of the type having a conductive plate-shaped support with an electric heating element and a plurality of heat conductive elements extending at right angles from the support each adapted to extend into a hair curler for transmitting heat thereto, the inventive improvements wherein the heat conductive elements project from the support by an extent amounting to a minor portion of the length of the hair curlers, each hair curler comprising a metal casing having a bottom portion shaped to interfit with one of the heat conductive elements, and having a heat insulating plastic coating on the outer surface of the casing except the shaped bottom portion, and .a heat insulating diaphragm in a parallel spaced relationship to the conductive plate-shaped sup port, the diaphragm being spaced from the conductive plate-shaped support a distance substantially less than the length of the hair curlers, the diaphragm including openings coaxial with the said conductive elements, the openings being of a suitable size for the hair curlers to extend therethrough an insulating cas
- Apparatus as claimed in claim 4 further comprising a first indicating light adapted to indicate operation of the electric heating element, and a second indicating light operating intermittently to indicate disconnection of the current supply due to the action of a thermostat in heat exchange relationship to the plate-shaped conductive support and connected in an electric circuit to the heating element.
