Device for supplying steam and hot air to the hair and eyelet,

The invention relates to a device for supplying steam and hot air on hair and face, which works with high efficiency «is electrically safe and in a simple way allowed the selection of the desired operating mode

According to a preferred embodiment of the invention, a hot air line leads from a hot air source to a hair dryer hood in order to supply it with hot air, and a steam line having a valve leads from a water heater to an outlet which supplies steam to the face. The steam line has a branch between the water heater and the valve, which is introduced into the hot air line in such a way that the air pressure in the air line selectively regulates the flow of hot air and steam to the hood and to the gas outlet. The device

is suitable for further optional operation «as explained below.

Home appliances in which water is immersed in a pair of Electrodes arranged at a distance from one another are heated "carry the risk of electric shock" if , the user inadvertently turns on the heater, before the device is filled and then touches the device and a faucet, for example, whereby the body of the user is enclosed in an electrical circuit, which is closed via the conductive water flow to earth. The invention is based on the object of reducing such a risk to a minimum the water flow is interrupted to such an extent that its electrical conductivity increases is limited to a safe value.

are, like preferably all other such fastening devices, protected against unintentional bodily harm.

According to the wing. 7, 9 and 10, a water trough 50 with side walls 51 is provided, in which water is filled and from which it flows through the opening 52 to the device. A receptacle 54 (FIG. 6) is provided vertically below the opening 52

"Rare walls 53 arranged" with the latter including a bottom 55 which is provided with a recess at 56, which forms an inclined feeder which is formed by rare walls 58 1st limited and opens into an outlet 60 vertically above the water heater 40. A pronounced rounding 57 of the bottom is provided in the vessel 54, which emerges from the opening 52 Water opposite. The trough 50 has sufficient water absorption capacity to accommodate a water supply sufficient to use the device · The diameter of the opening 52 is small »so that the water outflow from this opening is kept small, preferably in the form of discrete drops, and to achieve this, instead of one

^ Opening several openings are provided, which are from the trough open into the inclined feeder dos OefAsses 54.

The bottom of the Öefäsees 54 is compared to the diameter of the opening 52 is large, and the water-carrying capacity of the oef & sses is greater than the inlet capacity of the opening which adds water to the vessel. As a result of the downward inclination of the feed, "the feed speed preferably" increases so that the flow is in the longitudinal direction is distributed »whereby the mean flow area is reduced and the resistance is increased.

The acceleration of the water as a result of gravity during the palla from the opening 52 reduces the electrical Conductivity, since the water is separated into droplets, although this applies to a greater extent if several openings are used. A further breakdown of the water flow occurs when the water hits the inner edge of the floor of the container 5 * strikes and is deflected by this. the Ausnhmg 5θ forms a pouring point for shaping the Water flow so that it falls freely at the end of 60 * From the end of 60 there is a further acceleration due to gravity and a separation of the Kaaserstrones into drops. " before the water comes into contact with the electrically charged one Areas of the electrodes 44 and 46 arrives. In this catfish will in the device «in maximum electrical resistance with respect to a ground fault current flow a along the water flow achieved.

The water heater has a central outlet 7Q. the one with a steam line 72 is connected, which opens into a vertical outlet 74 and a horizontal channel 76 ″. Of the Steam exits from channel 76 via a valve 78 * that through a Druekfedex80 is spring-loaded in a closed position, The compression spring 80 is arranged between a holder 82 formed in the frame 47 and a circular projection 84 of the valve plate 78, which serves as a spring seat. If the valve is closed, this blocks the. Passage of steam from Channel 76 to outlet 86 by pressing the valve element against the lower edge of outlet 86.

The bayonet lock is Shown in Fig. Ha and 11b and consists of opposing projections 92 & ra Bohr 90 »which an L-shaped Slots in the wall of outlet 86 engage. The connecting tube 90 is a flexible tube 96 (Fig. 5) connected, which leads to a calibration mask 98 made of plastic.

The drain pipe 100 for the water heater (Fig. 12), the has the same diameter as the connecting pipe 90, can be locked in the same way «to drain water from the water heater.

The steam generated in the water heater 40 can pass through the branch 72 flow upwards, whereupon it flows into the hot air pipe 6 enters and flows upwards to the dryer hood. Steam inlet flaps 102 and 104 (FIGS. 15 and 13a) are on their lower Xanten 105 unö I06 pivotable on the inside wand <ler line 6 just below the upper joint IC stored.

In the upper wall of the water heater (Pig. 7) there is an opening 112, the cover U * of which is hinged at 116 to the top of the water heater. When calibrating the device in the Pig. 7, the cover 114 rests on the opening 112 as a result of its weight in order to close it, whereby the steam is directed through the medium outlet 70 to Russians (Pig. 12) is used to block the valve 78 in its open position and the device is pivoted into the position shown so that the water 70m from the heater can drain through the drain pipe 100, which is inclined near the bottom. In this position, the cover 214 swings into an open position _{/ in} order to enable the water to be drawn off in the specified manner. The electrodes 44 and 46 are located above the outflowing water and have no electrical contact with it.

When the device is in operation, it proves to be extraordinarily flexible with regard to the selection of its operating states using a minimum »mass of hand-operated control devices. The device can be used as a conventional hairdryer work. By setting the fan to the desired speed, the flaps 102 and 104 and the valve 78 are closed and the water heater 40 is empty. The openings 18 in the hood are dimensioned such that the openings in a commercially used dryer that air flows are passed around the hair at such a speed that the hair is dried to the maximum degree of effectiveness; the openings are smaller than they let in steam,

if this should be supplied by pure convection. If the user wants steam to be supplied to the hair, the water heater is filled with water "with the power switched on, steam is automatically generated" which enters the air line 6 as cooled steam "with the motor switched off and flaps 102 and 104 open {valve 78 closed) the steam rises by itself and enters the hood through the openings 108 in order to fill it. The steam can be forcibly supplied to the hair together with a stream of hot air by closing the bottom of the flaps 102 and 104 and switching on the OeblKses. After a certain time, the water in the water heater is used up and hot, dry air is automatically supplied to the hair without any control by the user. This is an effective way of putting hair on rollers and for this purpose care does not need to be taken to saturate the curls with water before laying them on. In order to add steam to the Qe & icht while the hair is being dried, the blower is switched on after the hose connection 90 has been inserted into the “open” valve 78 and the flaps 102 and 104 are now closed. The heated air enters at the base of the conduit 6 and is mostly forced into the hood and through the openings 18. As a result of the positive air pressure above the outlet Tk , a softening of steam upwards in the line 6 and to the hair is prevented and part of the air flows downwards through the outlet 7 to mix with the steam and this along the line fs for face & uslaae to lead · to steam the face has reached "1st'er avoid sufficiently cooled zn to burning of the skin" because the water heater produces slow Danpf and di · atm lines Ctosichtsauelass cause Kühlwlrkung.
