Definitions

  • the invention relates to a hairdryer according to the preamble of the main claim.
  • the object on which the invention is based is to use a conventional disposable or quartz pocket lighter or an interchangeable gas container to construct a safe, light, and simple hair dryer that is fit for travel.
  • a conventional gas pocket lighter or a gas container is used as a heat-generating part in a hairdryer housing equipped with a suction and a blow-out opening as well as a battery-operated blower.
  • the lighter or the gas container is to be inserted into the hairdryer housing by means of a recess so that the lever on the gas lever stop lug actuates by the thumb pressure exerted on the sole, the ignition and the gas outlet.
  • the lighter or the gas tank also serve to actuate a switch, so that the blower is started up shortly before the ignition.
  • the air baffle accommodated in the housing forms a connecting gap with the air baffle between the receiving chamber and that towards the hot air blowing nozzle _ _
  • a- Security by dispensing with the power grid b- Independence from limited cable lengths, from different types of sockets in different countries. This means that it can be used absolutely anywhere, such as in the car, on campsites, on bathing beaches, etc.
  • the lighter or gas container can be removed and used for the usual purpose. In this case, the hair dryer without a lighter is completely harmless even in children's hands.
  • thermodot attached to the housing surface forms an optical security. If for some reason a critical temperature is reached, the thermodot changes color. Then switch off the device. The light pressure applied to the lighter with the thumb is released. Thus, the lighter jumps back a few millimeters from its position due to the spring pressure of its gas lever, and as a result both the gas outlet and the operation of the blower are interrupted. This also happens if you leave the hair dryer out of your hand or put it down. This ensures that the device does not continue to run unintentionally.
  • the hair dryer according to the invention is simple and inexpensive to manufacture.
  • Figure 1 shows a hair dryer in a schematic representation without the housing cover.
  • 2 shows a nice side view of the hair dryer with the inserted lighter in operation (without housing cover);
  • 3 shows a perspective illustration of the housing cover;
  • FIG. 4 shows a perspective view of the housing without housing cover in a side view, seen obliquely from the front;
  • FIG. 5 shows a perspective view of the housing (without housing cover) with the lighter and the removed fan propeller in a side view, seen obliquely from behind;
  • Fig. 6 shows the hair dryer with the battery box cover removed with the lighter in perspective (rear view " “: view from an angle obliquely from the front);
  • FIG. 7 shows a perspective illustration of the hair dryer in operation (handling with the left hand);
  • FIG. 8 shows a perspective illustration of the hair dryer when handled with the right hand (front view seen obliquely from the side);
  • FIG. 9 shows the hair dryer in an embodiment for disposable lighters with flint ignition; schematic side view without housing cover, but with inserted lighter;
  • FIG. 11 shows the hair dryer for disposable lighters, Perspecti v ic shown in a front view, obliquely from the side ge see (with U-guide and disposable lighter).
  • a hair dryer (1) shown schematically in a side view without a housing cover, has a blower (2), a lighter receiving chamber (6) delimited from the air flow channel (5) by an air baffle (3) and air baffle (4).
  • the free-standing end (7) of the air baffle (3) is bent into the air flow channel (5), which is the free-standing end (8) of the air baffle (4) bent into the lighter receiving chamber (6).
  • the two free-standing ends (7, 8) form a connecting gap (9) between the air flow channel (5) and the lighter receiving chamber (6).
  • the lighter receiving chamber (6) has two lighter guide strips (12) and the limiting strips (10, 11).
  • the limiting strip (10) attached to the side of the air deflection plate (4) has a throttle lever stop lug (13).
  • the limiting strip (11) attached on the fan side has a mounting device (14) for the housing cover (la, FIG. 3).
  • the spring plate (16) attached to the front surface (1b) with a screw connection (15) ensures pressure on the inserted lighter (17, Fig. 2).
  • the fins (18) placed in the lighter receiving chamber (6) serve for the contact of the blower current line.
  • FIG. 2 shows a schematic side view of the hair dryer (1) with the inserted lighter (17) without a housing cover.
  • the throttle lever (17a) of the lighter (17) snaps onto the throttle lever stop lug (13) of the limiting strip (10) in such a way that when the lighter (17) is pushed further into the housing (1) the throttle lever (17a) yields, so that both the Gas outlet and the ignition of the gas take place.
  • the end face (19) of the lighter (17) compresses the fins (18) of the blower power line, so that the blower (2) is started to rotate in the direction of the arrow (2a).
  • the fan draws in the air perpendicular to the plane of the drawing, blows it through the air flow channel (5) in the direction of the arrow (2b) and through the warm air blowing nozzle (20).
  • a suction effect occurs in the connecting gap (9), so that fresh air into the lighter receiving chamber (6.)
  • the recess 21, FIG. 4
  • the lighter cooling slots 22, FIG. 4
  • This causes the lighter (17) to cool and the Lighter flame (17b) receives more oxygen per unit of time, whereby a complete combustion can take place.
  • the combustion takes place in the connecting gap (9).
  • the resulting heat is sucked into the air flow channel (5) and mixed with the blower air with the help of the curve (5a) and the semicircular arc (4a) of the air deflection plate (4) and blown out as warm air through the warm air blowing nozzle (20) (2c ).
  • air temperatures around 70 C were measured on the warm air blowing nozzle, which correspond to the temperature values of conventional hair dryers.
  • Fig. 3 the housing cover (la) is shown with the air intake opening (24) and with the thermodot (25) which changes color in the event of overheating.
  • the housing cover (la) is designed in such a way that, when assembled, it seals both the mounting surface (1c) and the edges of the air guide and air deflection plates (3, 4) in an airtight manner.
  • Fig. 4 the hair dryer housing shown schematically in Fig. 1 without housing cover is shown in perspective. It can be seen here that the air baffles and air deflection plates (3, 4), the limiting strips (10, 11) and the lighter guide strips (12) are arranged perpendicular to the mounting surface (1c).
  • An aluminum sheet (26) is provided as heat insulation on the mounting surface (1c), and also on the inside of the housing cover (la).
  • the recess (21) is designed so that its shape is adapted to the contours of the lighter (17) perpendicular to its longitudinal axis.
  • the battery box (27) can be seen on the back of the mounting surface (1c).
  • 5 shows the hair dryer housing (1) without the housing cover (la) in a perspective view. The most important components of the hair dryer according to the invention are shown here in a side view, seen obliquely from behind.
  • the lighter (17) is to be inserted into the recess (21) in the direction of the arrow (17c) so that the gas lever (17a) is directed upwards and the gas outlet valve (28) is directed downwards.
  • the gas flows directly into the opening of the connecting gap (9) on the lighter receptacle, where the combustion takes place.
  • the motor (29) with its shaft (30) is shown with the blower (2) removed, so that the vertical position of the shaft axis relative to the mounting surface (1c) is illustrated.
  • Fig. 6 the hairdryer is shown with the cover (31) of the battery box (27) removed and with the lighter (17).

  • the lighter (40) jumps in the direction of the spring plate (16a) until the throttle lever (42 ) on the rubber cylinder (37), so that the throttle is pressed simultaneously with the ignition and the gas is discharged.
  • the spring plate (16a) bends in such a way that it makes contact with the fins (18a) and thereby starts the fan (2) shortly before the actual ignition (FIG. 10).
  • the gas combustion in the connecting gap (9) and the hot air discharge through the hot air blowing nozzle (20) take place as in the previous descriptions.
  • FIG. 11 shows the hair dryer according to the invention, the U-guide (36) and the disposable lighter (40) in a perspective view. From this it can be seen that the shape of the recess (21a) is adapted to the contours of the disposable lighter (40) transversely to its longitudinal axis.
  • the gas lighter can be easily replaced by a gas container, in which case the ignition device of any type is fixed in the housing of the hair dryer.
  • the ignition device can be actuated either by a separate switch attached to the hairdryer housing or by means of the gas container by pushing it into the hairdryer.

Abstract

Le corps chauffant, le commutateur, le mécanisme d'allumage et le récipient de gaz d'un sèche-cheveux sont formés par un briquet usuel à gaz (17), de préférence pourvu d'un allumage à batterie ou à quartz piézoélectrique, ou par un autre mode de réalisation d'un briquet jetable ayant un allumage à silex (40). L'utilisation d'un récipient remplaçable avec un dispositif d'allumage solidaire du boîtier du sèche-cheveux fait également partie de l'invention. l'allumage se fait lorsque l'on introduit le briquet (17, resp. 40) dans la cavité (21, resp. 21a) du boîtier (1) du sèche-cheveux, le ventilateur (2) étant mis en marche juste avant, par contact avec les lames (18, resp. 18a). Le courant d'alimentation du ventilateur est fourni par des piles jetables ou par des accumulateurs rechargeables. Le sèche-cheveux est arrêté simplement en relâchant la pression exercée par le pouce, ce qui assure en outre que l'appareil ne sera pas involontairement laissé en marche. Le briquet (17, resp. 40) peut être retiré à volonté du boîtier (1) du sèche-cheveux et être utilisé normalement comme tel. Etant complètement indépendant du réseau, ce sèche-cheveux est absolument sûr dans des pièces humides et peut être utilisé partout. Son faible poids et ses petites dimensions le rendent particulièrement approprié pour des voyages. L'appareil peut être aisément et économiquement produit.
