(13) FIGS. 1-10 show the hairdressing device 1 in accordance with a first embodiment of the invention, and FIGS. 11-18 show a second embodiment of the hairdressing device. In the following the common features of the two embodiments of the hairdressing device 1 will be described and the specific features of the two embodiments will be pointed out. As seen in the figures, for instance FIGS. 1-4 and 11-14, a holder 2 is arranged with a plurality of combing teeth 20 and hollow teeth 50 extending from the holder 2. These combing teeth 20 and hollow teeth 50 constitute a combined drying and combing section. The holder 2 has an air distribution chamber 3, see for instance FIGS. 9, 10, 15 and 16. The holder 2 as illustrated in the figs has an attachment portion 10 for connection to an apparatus suitable for supplying an air flow into the air distribution chamber 3, for instance a hot air source, e.g., a blow-dryer, a hose with a nipple etc., from where the hot air is blown into the air distribution chamber 3. The hairdressing device 1 may also be integrated as a part of hairdressing apparatus, such as being a fixed part of the hairdressing apparatus, wherein hairdressing apparatus generates a flow of air, such as is known from present blow dryers.

(14) Each hollow tooth 50 is configured with a channel 51 that in accordance with the first embodiment as shown in FIGS. 1-10 has an outlet opening 52 for the air to flow from the air distribution chamber 3 and out through the outlet opening 52, and according to the second embodiment the channel 51 has two outlet openings 52a, 52b, see FIGS. 11-15. The outlet openings 52 are oriented inclined relative to a central longitudinal plane L through the holder 2, and may as shown for instance in FIGS. 9 and 15 form an acute angle with the central longitudinal plane L. When in use the air flow as distributed through the channels 52 of the hollow teeth 50, will be directed away from the scalp and towards the hair to be dried and formed. The outlet openings 52, 52a, 52b are positioned in a distance above the tips 21 which are situated closest to the scalp and are inclined in a direction upward from the tips 55 of the teeth 50. The channel 51 has an inclined inner channel wall 80 forming a first portion of the channel 81 adjacent the air distribution chamber 3 with a tapering shape for direction of the air flow into a second portion of the channel leading the airflow out through the outlet opening(s) 52, 52a, 52b. Air holes 90 are arranged in between the hollow teeth 50 for supply of air also into the area of the combing teeth 20, wherein the air supply is to be directed in the extension direction of the combing teeth, perpendicular to the holder 2.

(15) The hollow teeth 50 and the combing teeth 20 are positioned in an alternating pattern where a hollow tooth is placed next to a combing tooth. The hollow teeth 50 are configured for the air to flow out from outlet openings 52 at opposite sides A, B of a central longitudinal plane L through the holder 2. As the air flow is distributed symmetrically on both sides of the central longitudinal plane L, hairdressing device may easily be employed in most hand-held positions and combing directions and may be used equally by left and right-handed users.

(16) In the first embodiment, see FIG. 1-10, the distribution of air flow through the hollow teeth 50 is carried out by every other hollow tooth 50 being turned oppositely to the next one, so that the outlet openings 52 of every other hollow tooth 50 is facing a diametrically opposite direction of the next hollow tooth, see for instance FIGS. 5-9.

(17) By this alternating pattern of the hollow teeth 50, the air flow exits from every other hollow tooth at one side A of the central longitudinal plane and from the remaining hollow teeth at other side B of the central longitudinal plane. The hollow tooth has an exterior combing structure 58 surrounding the channel 51 and being positioned at both sides of the central longitudinal plane L so that a combing effect is also achieved by the hollow teeth 50. As seen the contours or exterior outlines of the exterior combing structures 58 match those of the combing teeth.

(18) As seen for instance in FIGS. 1-3, the combing teeth 20 comprises two tooth sections positioned at equal distances form the central longitudinal plane L. The tooth sections are arranged with an inclined orientation so that the lateral distance between tips 21 of the pair of combing teeth 20 at each side of the central longitudinal plane L is larger than the lateral distance between roots 22 of the combing tooth. Likewise, the lateral distance between tips 70, 71 of the exterior combing structure 58 at each side of the central longitudinal plane L is larger than the lateral distance between roots 72, 73 of the exterior combing structure. As seen in the FIGS. 1-3, the lateral distances of the combing teeth 20 correspond to those of the hollow teeth 50, and thus the drying and combing zone of the hairdressing device 1 has a uniform appearance when moving in direction of the central longitudinal plane L.

(19) An alternative configuration of the hollow teeth 50 to direct the air to flow out from outlet openings 52 at opposite sides A, B of a central longitudinal plane L, is suggested in accordance with the second embodiment of the hairdressing device as shown in FIGS. 11-17. The channels 51 run from the air distribution chamber 3 and is separated into a first opening 52a and a second opening 52b facing the opposite sides A, B of the central longitudinal plane L. See FIGS. 15 and 16. These hollow teeth are also surrounded by external combing structures 58 and the dimensions and external shape of the hollow teeth 50 correspond to those of the combing teeth 20, thereby providing the hairdressing device 1 with an external shape that is similar to the first embodiment, is uniform along the central longitudinal plane L. The cross-section of the combing teeth 20 and the hollow teeth 50 as shown in first embodiment in FIGS. 1-10 is right-sided, whereas the cross sections of the external combing structures 58 and the combing teeth 20 show curved outer sides, as seen in FIGS. 11-13.
