Description

The invention relates to a device according to the preamble of the preamble of claim 1 and 2, respectively.

Such a device for a steam treatment of head hair is for example from the US 4,314,138 A known. Another steam generator of this genus is z. In document GB 2158210 A disclosed. There is a risk that the boiler can be overfilled with water, which can affect the production of steam. Namely, it is possible to fill the boiler to a steam outlet opening, whereby boiling, flowing water from the boiler is pressed into the device and can even get into a treatment dome of the steam treatment apparatus, which is a danger of scalding for a person to be treated can bring.

The invention is therefore based on the object to provide a generic same device that does not have this disadvantage by simple measures.

This object is achieved according to the features of the characterizing part of claim 1 or 2. Thus, a sufficient wall space is always available when operating the device in the boiler used.

The invention will be explained in more detail with reference to two exemplary embodiments.

Fig. 1 shows a device 2 with a boiler 1 for generating water vapor for example, a steam treatment of hair of the head, wherein the inserted into a receptacle 15 boiler 1 has a top refill closure 3 and a steam outlet opening 4. The steam outlet opening 4 is arranged in the upper side region 5 of the boiler 1. The boiler 1 is provided below the steam outlet opening 4 with an outflow opening 6, wherein a lower edge 7 of the steam outlet opening 4 and a lower edge 8 of the outflow opening 6 forms a height H of a wall space W, and wherein the steam outlet opening 4 with a steam channel coupling 9 of a steam channel 10th and the outflow opening 6 corresponds to a closure part 11 of the receptacle 15.

By simple measure, the closure part 11 is formed by an inner wall 16 of the receptacle 15.

The steam channel coupling 9 or the steam outlet opening 4 and the outflow opening 6 are provided with an elastic seal 13,13.1, whereby with appropriate dimensioning of the receptacle 15 a liquid-tight and pressure-resistant steam channel coupling 9 is created in relation to an inner wall 16 of the receptacle 15 as a sealing surface.

To refill the kettle 1, it is removed from the receptacle 15 and water is admitted through the closure 3 until it flows out of the outflow opening 6, resulting in a maximum filling height, which is determined by the lower edge 8 of the outflow opening 6. Then, the boiler 1 is again inserted into the receptacle 15, whereby the outflow opening 6 is closed by the closure part 11 and by the inner wall 16. This inevitably results in an enlarged wall space W, which is necessary for bubbling, boiling water 20 during operation of the device 2, whereby spilling over of bubbling, boiling water 20 in the device 2 and thus a scalding injury is prevented.

Fig. 2 shows a side view II-II on the boiler 1 after the Fig.1 from which the seals 13, 13.1 further emerge in a plan view. The boiler 1 may optionally have a circular, rectangular or elliptical cross-sectional area.

Fig. 3 shows a side view III-III on a steam channel inlet 17 of the receptacle 15, wherein the steam channel inlet 17 is arranged in the plane of the inner wall 16 and corresponds to the steam outlet opening 4 of the seal 13. The outflow opening 6 is liquid-tight or vapor-tight closed by the inner wall 16 of the receptacle 15, so that only steam from the steam outlet opening 4 can flow into the steam channel inlet 17.

Fig. 4 shows as a second embodiment, a device 2 with a boiler 1.1 for generating water vapor for example, a steam treatment of hair, wherein the inserted into a receptacle 15 boiler 1.1 has a top refill 3.1 and a steam outlet opening 4.1 arranged. The steam outlet opening 4.1 is arranged in the upper side region 5 of the boiler 1.1. The steam outlet opening 4.1 is enlarged downward with a depth T, wherein the enlarged part V of the steam outlet opening 4.1 forms an outflow opening 6.1, wherein the depth T forms a height H of a wall space W, wherein a peak HP of the height H by a lower edge 18 of a Steam channel input 17 of the steam channel 10 is predetermined. Below the steam channel input 17, a region 12 of an inner wall 16 of the receptacle 15 closes the outflow opening 6.1.

The steam channel coupling 9.1 is provided with an elastic seal 13.2, whereby a liquid-tight and pressure-resistant connection in relation to the area 12 of the inner wall 16 of the receptacle 15 is provided as a sealing surface.

To refill the boiler 1.1 this is removed from the receptacle 15 and as long as water 20 is admitted through the shutter 3 until it flows out of the outflow opening 6.1, resulting in a lower level 8.1 a maximum filling level. This inevitably results in a wall space W, which is necessary for bubbling, boiling water 20 during operation of the device 2. Then the boiler is 1.1 again in the recording 15 used, wherein below the steam channel entrance 17, a region 12 of an inner wall 16 of the receptacle 15, the outflow opening 6.1 closes.

Fig. 5 shows a side view VV on the boiler after the Figure 4 , The steam outlet opening 4.1 and the outflow opening 6.1 together have a shape of an upstanding ellipse 19, wherein a sealing ring in the form of an ellipse 19 is provided as the seal 13.2.

Fig. 6 shows a side view VI-VI on a steam channel inlet 17, wherein the steam channel inlet 17 is arranged in the plane of the inner wall 16.

Fig. 7 shows in an overall view of a designed as a steam treatment apparatus 14 with a steam hood 31 device 2 for a steam treatment of hair of the head, wherein the steam hood 31 is provided with a steam distribution ring 37. In this embodiment, the boiler 1.1 is provided with an electric heater 21 and an electrical coupling 22 as a structural unit 32, which is completely removed from the receptacle 15. In the Fig. 1 . 2 . 4 and 5 this unit 32 is indicated by dashed lines. Preferably, the boiler 1.1.1 is inexpensively made of heat-resistant plastic and can thus be removed in the upper area without the risk of burns. Alternatively, a heat-insulated handle can be provided. For fixing the boiler 1.1 in the receptacle 15, the steam treatment apparatus 14 is provided with a pivot cover 33, which is shown in an open position. The steam treatment device 14 has a handle 34 for displacing the steam hood 31. Furthermore, a tripod connection 35 is provided for connection to a floor stand, not shown, with which the steam treatment device 14 can also be adjusted in height. For electrical power supply, the steam treatment device 14 has a network connection 36. For the operation of the steam treatment device 14, a display / control panel 38 is provided.
