[0007] The invention aims to create an improved extractor hood with a mounting device and an improved wall mounting rail, as well as an improved method for mounting an extractor hood.

[0008] According to the invention, this problem is solved by a cooker hood with a mounting device and a method for mounting a cooker hood with the features of the main claims. Advantageous embodiments and further developments of the invention are described in the following dependent claims.

[0009] To attach the extractor hood to the wall mounting rail with minimal gap to the upper cabinet or ceiling, the hood can be slid onto the rail, essentially parallel to the cabinet or ceiling. To prevent the hood from falling, it can be locked into place using a locking mechanism. The extractor hood can then be screwed to the wall mounting rail.

[0010] The advantages achievable with the invention include, in addition to a gap-free mounting of the extractor hood, easy installation and fall protection of the extractor hood.

[0011] A range hood with the following features is presented: a wall mounting rail with at least one undercut; and a mounting device, wherein the mounting device has at least one contact surface and at least one locking device, wherein the locking device is designed to engage in the undercut of the wall mounting rail when the contact surface is pushed onto a contact surface of the wall mounting rail.

[0012] A range hood is a household appliance that includes a fan and a filter system for extracting and filtering cooking fumes. Range hoods are designed to be mounted on a wall above a cooktop. This is achieved using a mounting bracket, which is part of the range hood's housing, and a wall mounting rail. The wall mounting rail is a rail that can be attached to the wall and has a contact surface for the range hood and at least one undercut for engaging the locking mechanism. For example, the wall mounting rail can be screwed to the wall.

[0013] The locking mechanism can have a movable latch. The latch can protrude beyond the mounting surface in a first position and be at least partially retracted behind the mounting surface in a second position. The latch can be rotatably mounted in the locking mechanism. The latch can also be guided in a track. The latch can have an incline to facilitate its movement from the first to the second position when slid onto the wall mounting rail.

[0014] The trap can be pushed into the first position by a spring. The trap can be moved against the spring force into the second position. A spring allows the trap to snap shut quickly. The spring-assisted movement can produce a clicking sound, indicating that the trap has engaged.

[0015] The trap may have an actuating device for retracting the trap. This actuating device may be a lever coupled to the trap. The actuating device allows the trap to be held in the second position, thus facilitating easy removal of the extractor hood.

[0016] The mounting surface can be horizontally oriented when installed. This horizontal mounting surface ensures the extractor hood is securely positioned without the risk of slipping.

[0017] The mounting surface can be designed as an inclined sliding surface. A sliding surface can be an inclined plane onto which the extractor hood can be slid. The incline allows the extractor hood to be positioned lower and slid into its final position. This prevents contact with a surface located above the extractor hood.

[0018] The mounting device may include a screw connection in which one axis of rotation of the screw connection is oriented substantially parallel to the mounting surface. A screw connection may comprise a screw, a through-hole for the screw, and a threaded bushing for the screw. The mounting device may at least partially encompass the screw connection. The remainder of the screw connection may be part of the wall mounting rail. Due to the parallelism of the axis of rotation and the mounting surface, a relative position between the extractor hood and the wall mounting rail can be established via the screw connection.

[0019] The mounting fixture can be designed as a stamped and bent part. A stamped and bent part can be manufactured cost-effectively in large quantities. Alternatively, a sheet metal part for the mounting fixture can be cut by jet cutting and subsequently bent.

[0020] The undercut can be formed as a recess in the wall mounting rail. The edge of the recess can form the undercut.

[0021] Furthermore, a method for mounting a cooker hood according to the approach presented here is introduced. In this method, at least one locking device of the mounting fixture engages in the undercut during a single step of the locking process while the mounting surface is being slid onto a mounting surface of a wall mounting rail, according to the approach presented here.

[0022] An embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows Fig. 1 a representation of a cooker hood according to an embodiment with a wall mounting rail according to an embodiment; Fig. 2 a sectional view through a mounting device according to an embodiment and a wall mounting rail according to an embodiment; Fig. 3 a sectional view through a mounting device mounted on a wall mounting rail according to an embodiment; Fig. 4 a sectional view through a mounting device screwed to a wall mounting rail according to an embodiment; Fig. 5 a sectional view through a mounting device with an inclined contact surface according to an embodiment and a wall mounting rail with an inclined contact surface according to an embodiment; Fig. 6 a sectional view through a mounting device with an inclined contact surface mounted on a wall mounting rail according to an exemplary embodiment; Fig. 7 a sectional view through a mounting device with an inclined contact surface mounted on a wall mounting rail according to a further embodiment; and Fig. 8 a flowchart of a method for mounting a cooker hood according to an exemplary embodiment.

[0023] Fig. Figure 1 shows a representation of a range hood 100 according to an exemplary embodiment with a wall mounting rail 102 according to an exemplary embodiment. The range hood 100 is intended for installation below a wall cabinet or under the ceiling of a room. A small gap between an upper edge 104 of the range hood 100 and the underside of the wall cabinet or the ceiling is desired. The wall mounting rail 102 is aligned parallel to a lower edge of the wall cabinet or the ceiling and is attached to a wall of the room or to the back of the wall cabinet. During installation, the range hood 100 is slid onto the wall mounting rail 102, essentially parallel to the underside or the ceiling. A contact surface of the range hood then slides onto a contact surface 106 of the wall mounting rail 102.At least one locking mechanism of the extractor hood 100 engages in an undercut of the wall mounting rail 102. This fixes the extractor hood 100 to the wall mounting rail 102, allowing it to be screwed to the wall mounting rail 102 in a subsequent assembly step.

[0024] Fig. Figure 2 shows a sectional view through a mounting device 200 according to an exemplary embodiment and a wall mounting rail 102 according to an exemplary embodiment. The mounting device 200 is a component of a cooker hood 100, such as those found, for example, in Fig. The wall mounting rail 102 is shown in Figure 1. The wall mounting rail 102 essentially corresponds to the wall mounting rail in Figure 1. Fig. 1. The mounting surface 106 is aligned perpendicular to the wall 202 and therefore horizontally.

[0025] The locking device 204 comprises a rotatably mounted latch 206. The latch 206 is pressed by a spring 208 through an opening in a contact surface 210 of the mounting device 200. When the contact surface 210 is slid onto the contact surface 106 of the wall mounting rail 102, the latch 206 is moved back against the spring 208. When the contact surfaces 106 and 210 have been slid far enough over each other, the spring 208 presses the latch 206 into a recess 212 of the wall mounting rail 102. The latch 206 engages in an undercut 214 of the recess 212.

[0026] In one embodiment, the locking device 204 has no spring. Here, the latch 206 is pulled through the opening in the contact surface 210 by gravity.

[0027] The latch 206 has an actuating device 216. The actuating device 216 allows the latch 206 to be lifted out of the recess 212 in the wall mounting rail 102 in order to remove the extractor hood 100. The actuating device 216 is designed as a lever 216.

[0028] Fig. Figure 3 shows a sectional view through a mounting device 200 mounted on a wall mounting rail 102 according to an exemplary embodiment. The wall mounting rail 102 and the mounting device 200 essentially correspond to the illustration in Figure 3. Fig. 2. The mounting surfaces 106 and 210 rest against each other, and the latch 206 is engaged in the recess 212. Additionally, the extractor hood 100 is connected to the wall mounting rail 102 via a screw connection 300. One axis of rotation of the screw connection 300 is aligned parallel to the mounting surfaces 106 and 210. The extractor hood 100 is positioned with a small gap 302 to the surface 304 located above it. Here, surface 304 is the underside of a wall cabinet located above the extractor hood 100. Surface 304 could also be a ceiling.

[0029] A safety device 204 for a cooker hood 100 is presented for installation / disassembly.

[0030] A range hood 100 is slid onto a wall mounting rail 102 due to the presence of already installed cabinets 304 and is fastened to the rail 102 with screws 300. With the approach presented here, a gap 302 between the hood 100 and the cabinets 304 can be avoided. To prevent falling during installation and removal, the range hood 100 and the wall mounting rail 102 have a fall protection device 204.

[0031] The hood 100 is currently lifted using a slanted undercut to prevent it from falling. However, this creates a gap between the hood 100 and the cabinet 304.

[0032] Alternatively, screws can be pre-installed and the hood 100 attached by subsequently screwing on nuts. However, the screws are difficult to access, and with a heavy hood 100, it is necessary for additional workers to support the weight during installation.

[0033] The approach presented here enables simpler assembly of the hood 100 by means of a snap-in system 204. The snap-in system 204 also serves as a fall arrestor for safe handling when loosening the screws 300 during disassembly.

[0034] The locking bracket 206 is displaced when the extractor hood 100 is pushed onto the wall mounting rail 102 and locks into the recesses 212 of the wall mounting rail 102 in the final position.

[0035] In other words, a range hood 100 is presented with a wall mounting rail 102, which can be mounted on the room wall 202 or the back panel 202 of a furniture, for receiving and storing the range hood 100. The range hood 100 is mounted in or under a kitchen cabinet 304. The gap 302 between the kitchen cabinet 304 and the range hood 100 should be as small as possible.

[0036] To facilitate and improve the safety of installation, while simultaneously maintaining a small gap 302, the extractor hood 100 has a locking element 206 which engages in a recess 212 of the wall mounting rail 102, thus preventing the extractor hood 100 from sliding off the wall mounting rail 102. In the illustrated embodiments, the locking element 206 engages in a recess 212 of the contact surface 106 of the wall mounting rail 102.

[0037] In one embodiment, the mounting surface 106 is arranged horizontally in the assembled state. The extractor hood 100 is secured to the wall mounting rail 102 by means of a screw connection 300, comprising a screw and a bushing.

[0038] Fig. Figure 4 shows a sectional view through a mounting device 200 screwed to a wall mounting rail 102 according to an exemplary embodiment. The illustration essentially corresponds to the illustration in Fig. 3. In addition, another screw connection 400 is arranged perpendicular to the contact surfaces 106, 210.

[0039] Fig. Figure 5 shows a sectional view through a mounting device 200 with an inclined contact surface 210 according to an exemplary embodiment and a wall mounting rail 102 with an inclined contact surface 106 according to an exemplary embodiment. The illustration essentially corresponds to the illustration in Figure 5. Fig. 3. In contrast, the contact surfaces 106, 210 are designed as sliding surfaces sloping away from the wall 202. The axis of rotation of the screw connection 300 is aligned at an angle to the contact surfaces 106, 210 and is essentially perpendicular to the wall 202.

[0040] The mounting surfaces 106 and 210 form an inclined plane on which the extractor hood 100 can slide into its final position. This allows the extractor hood 100 to be mounted at a greater distance from surface 304, thus simplifying installation.

[0041] In one embodiment, the mounting surface 106 of the wall mounting rail 102 is inclined, with one edge of the mounting surface 106 facing the wall 202 being higher than an edge of the mounting surface 106 facing away from the wall 202. The wedge thus formed facilitates sliding the extractor hood 100 onto the wall mounting rail 102 and thus positioning it in the final position.

[0042] Fig. Figure 6 shows a sectional view through a mounting device 200 with an inclined contact surface 210, mounted on a wall mounting rail 102 with an inclined contact surface 106, according to an exemplary embodiment. The wall mounting rail 102 and the mounting device 200 essentially correspond to the illustration in Figure 6. Fig. 5. Here the screw connection 300 is screwed in and the latch 206 is engaged in the wall mounting rail 102.

[0043] Fig. Figure 7 shows a sectional view through a mounting device 200 with an inclined contact surface 210, mounted on a wall mounting rail 102 with an inclined contact surface 106, according to a further embodiment. The wall mounting rail 102 and the mounting device 200 essentially correspond to the illustration in the Fig. 5 and Fig. 6. In contrast, here the axis of rotation of the screw connection 300 is as in the Fig. 2 to 4 are aligned parallel to the mounting surfaces 106, 210. This means the axis of rotation is angled relative to the wall 202. The angled orientation of the screw connection 300 allows the position of the extractor hood 100 relative to the wall mounting rail 102 to be changed. The gap dimension 302 can be adjusted via the screw connection 300 and the angled mounting surfaces 106, 210.

[0044] In one embodiment, a rotational axis of the screw connection 300 is aligned parallel to the contact surface 106. The contact surface 106 serves as a sliding surface. The position of the extractor hood 100 can be adjusted by means of the screw connection 300, i.e., the gap 302 can be minimized or a desired installation depth achieved.

[0045] Fig. Figure 8 shows a flowchart of a method for mounting a cooker hood according to an exemplary embodiment. The method can be used to mount a cooker hood such as those found in the Fig. The process is as shown in Figures 1 to 7. To mount the extractor hood, a mounting surface is placed onto a mounting surface of a wall-mounted bracket. The extractor hood is then slid along the mounting surfaces towards the wall. This displaces a locking mechanism of the extractor hood's mounting bracket. Once the extractor hood has been slid far enough towards the wall, the locking mechanism engages in an undercut of the wall-mounted bracket in an 80° increment. This secures the extractor hood against falling. The extractor hood can then be screwed to the wall-mounted bracket.
