PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf eine Vorrichtung zur Erzeugung von erwärmter Druckluft an Heißluftduschen u. dgl. für Haar- und Körperpflege, solcher Art, bei der der von einem Elektromotor angetriebene Ventilator die Luft über einen elektrisch beheizten Wider-' stand bläst.The invention relates to a device for generating heated compressed air on hot air showers and the like for hair and body care, of the kind in which the of an electric motor driven fan blows the air through an electrically heated resistor stand blowing.

Die bekannten Vorrichtungen dieser Art be-The known devices of this type

ιό als Träger der ganzen Vorrichtung und befestigen auf der einen Seite den Eektromotor und vor dem Einsaug oder Ausblas einen elektrischen Widerstand.ιό as a carrier of the whole device and attach the electric motor on one side and an electrical resistance before the intake or exhaust.

Gemäß der Erfindung ist jedoch der mit Antrieb und Heizvorrichtung versehene Ventilator, nochmals in einem besonderen, vorteilhaft kugelförmigen Gehäuse untergebracht.According to the invention, however, the fan provided with a drive and heating device, again housed in a special, advantageously spherical housing.

Diese Anordnung gestattet eine erhebliche Ermäßigung der Herstellungskosten. Während nämlich sonst die sämtlichen Einzelteile sowohl einzeln verkapselt, um unachtsame Benutzer vor Schaden zu bewahren, als auch .■". gleichzeitig so ansehnlich ausgeführt werden müssen, daß sie im'Wohnraum, Friseursalon Usw. gebraucht werden können, ist im vorliegenden Falle nur ein einziges Gehäuse erforderlich, das billigst mit dem erforderlichenThis arrangement allows a significant reduction in manufacturing costs. While namely otherwise all the individual parts both individually encapsulated, to careless users to protect them from damage, as well as. ■ ". at the same time be so attractive have to be in the living room, hairdressing salon Etc. can be used, in the present case only a single housing is required, the cheapest with the necessary

; schmückenden Beiwerk versehen werden kann. ; Das Gehäuse soll nun nicht,' wie dies bei Schutzgehäusen üblich ist, den Formen der eingeschlossenen Vorrichtung möglichst genau folgen, sondern den ganzen Ventilator mit seinen Hilfsvorrichtungen mit größerem Spielraum umschließen, weshalb z.B. eine Kugel- ; decorative accessories can be provided. ; The case should now not 'like this in the case of Protective housing is common, the shapes of the enclosed device as closely as possible but the whole fan with it enclose its auxiliary devices with greater clearance, which is why, for example, a ball

35_t oder Eiform benutzt wird. Hierdurch wird nicht nur die Herstellung des Schutzgehäuses vereinfacht, sondern der vorhandene Hohlraum wirkt günstig auf die Arbeitsweise der Vorrichtung ein.35 _t or egg shape is used. This not only simplifies the manufacture of the protective housing, but the existing cavity has a favorable effect on the operation of the device.

Wird die ganze Vorrichtung in dem Kugelgehäuse im wesentlichen nur an einer einzigen Stelle befestigt, so daß dieselbe ringsum von Luft umspült ist, so wirkt die zwischenliegende, ständig erneuerte Luft ' wärmeisolierend und schalldämpfend.If the entire device in the ball housing is essentially only a single one So that it is surrounded by air all around, so the intervening, constantly renewed air 'heat-insulating and sound-absorbing.

Infolge des eingeschlossenen Luftraumes um den Ventilator kann die Heizvorrichtung besser ausgenutzt werden, da dieselbe die Luft im Zustande geringerer Beschleunigung berührt. Da das Ventilatorgehäuse vor unachtsamer Berührung geschützt ist, so kann dasselbe auch als Heizfläche mitbenutzt werden, indem die Heizvorrichtung in unmittelbarer Nähe desselben angeordnet wird. Auch die Kühlung des Elektromotors wird nur dadurch ohne Schaden für die gleichmäßige Wärme der erzeugten Druckluft möglich, wenn ein mit entsprechendem Spielraum um die ganze Vorrichtung greifendes Gehäuse vorhanden ist.As a result of the enclosed air space around the fan, the heating device can do better be exploited, since it touches the air in a state of lower acceleration. Since the fan housing is protected from careless contact, the same can be done can also be used as a heating surface by placing the heating device in the immediate vicinity the same is arranged. The cooling of the electric motor is also only thereby without Damage to the uniform heat of the compressed air generated is possible if one is used accordingly There is room for the entire device gripping housing.

Ein weiterer Vorteil des zweiten Gehäuses beruht ferner in der Möglichkeit, die Regelung des elektrischen Stromes, die sich in ,Rücksicht-auf'die Laienbenützung, die räumlichen Verhältnisse und · die Wohlfeilheit der Einrichtung schwierig gestalten würde, vermeiden zu können.Another advantage of the second housing is based on the possibility of the regulation of the electric current, which is in "consideration for" lay use, the spatial Conditions and the cheapness of the institution would make it difficult to avoid to be able to.

Claims

The suction port is connected to the electric heater, the air flow more from the side of the electrical resistance or more from the. Side of the windings of the motor, so can be brought about a sufficient gradation in the degrees of heat of the conveyed air without interfering with the electrical conditions. The windings of the motor and the electrical resistance act ίο in this case like two heat generators with different capacities connected to one another depending on the requirements. If this slide for deflecting the air flow is made so narrow that it can only cover a part of the air inlet, it is possible to set it in the middle of the air jet so that the ratio of the air flowing over the two heat generators is still arbitrary can be set (■ {at the same time, however, the air jet is throttled accordingly or the air volume is reduced. In order to be able to give this reduced air volume the normal or a higher pressure, or to change the pressure conditions within any limits A device for changing the cross-section as desired can also be provided behind the air mover. The drawing shows an exemplary embodiment of the invention 'Both side walls of the fan have cutouts as Suction openings, in front of which the windings of the electric motor b. and in front of the other the heating resistor e is arranged. The whole device is arranged at an angle opposite the air inlet 'h in the ball housing, in particular to bring the motor as close as possible to the air inlet, while the outlet g at the periphery of the fan opens directly into the outlet connection f of the ball housing. The hose line is connected to the socket f of the spherical housing, while the suspension device engages the diametrically opposite parts of the spherical housing Air flow can be deflected either more towards the heating resistor e or the windings of the electric motor 6, for the purpose of regulating the degree of heat of the conveyed air. In the middle position, the narrow slide reduces the cross section of the air inlet h and thus the amount of air conveyed With the aid of the device t, the compressed air jet can be throttled and the pressure of the compressed air can be changed

1. With an electric drive motor and electric heater provided fan for generating heated compressed air in hot air showers, characterized in that 75 / that the fan and its auxiliary devices by a special, advantageous' round housing (a) is enclosed with clearance, on which it is advantageous is attached only in a few 'places' in order to create a simple joint closure for the individual parts, a heat and sound insulation to the outside.

2. Apparatus according to claim 1, 85 'characterized in that within the ■ common, advantageously spherical housing (a) a fan with two suction openings, in front of which the windings of an electric drive motor (b) and in front of which the electric heating device (e) is arranged opposite an air inlet in the housing so that the amount of air sucked into the housing and the flows directed towards the two fan suction openings either simultaneously or each individually by means of a slide which is narrower than the air inlet width Reduction of the flow cross-sections or lengthening of the flow path can be reduced for the purpose of changing the degree of heat of the compressed air.
