Description

Technical Field

[0001] The present invention relates to a door for a household cooking appliance and a household cooking appliance having such a door. Background Technology

[0002] Household cooking appliances can have a cooking chamber with a door pivotally fixed to it. The door can have an inner window facing the cooking chamber, an outer window facing away from the cooking chamber, and an intermediate window disposed between the inner and outer window panels. For household cooking appliances with a ventilated door, it may be necessary to remove the door to clean the inner and intermediate window panels. Therefore, it is desirable that the door be easily removable. Summary of the Invention

[0003] In light of this background, the objective of this invention is to provide an improved door for household cooking appliances.

[0004] Therefore, a door for household cooking appliances is proposed. The door includes an outer window panel, an inner window panel, at least one intermediate window panel disposed between the outer and inner window panels, and a window panel positioning device for positioning the at least one intermediate window panel on the door, wherein the window panel positioning device is supported on the door in a manner rotatable about a rotation axis, and wherein, when the at least one intermediate window panel is guided toward the outer window panel, the window panel positioning device pivots about the rotation axis such that the window panel positioning device surrounds the at least one intermediate window panel.

[0005] The window slat positioning device is rotatably supported on the door, thereby ensuring that the window slat positioning device is permanently connected to the door. The pivoting movement of the window slat positioning device allows the user to easily disassemble and reinstall the door.

[0006] The household cooking appliance can be a stove, oven, microwave oven combination, double oven, etc. Preferably, the household cooking appliance includes a cooking chamber, and the door is fixed to the cooking chamber, for example, in a pivotable manner. Hinges can be provided for this purpose. The hinges can be coupled to the door's support frame. However, this is not mandatory. Alternatively, the door can also be mounted on a baking backwagen or similar device that can be pulled out of the cooking chamber. In this case, the door is not pivotally fixed to the cooking chamber, but can move linearly relative to the cooking chamber.

[0007] The door specifically includes at least one door support. The door support is particularly positioned between the inner and outer window panels. The door support is particularly fixedly connected to the outer window panel. Preferably, two door supports, namely a first door support and a second door support, are provided, fixedly connected to the outer window panel. The door support is mounted on the outer window panel on its side and moves along the y-direction or height direction of the cooking appliance or door when the door is closed. The door support is mounted on the outer window panel on its back side, for example, glued to the outer window panel. The window panel positioning device can be rotatably supported on one of the door supports. However, the window panel positioning device can also be rotatably supported on any other component of the door. Preferably, the axis of rotation is oriented parallel to the height direction. That is, the axis of rotation is vertically positioned. However, the axis of rotation can also be oriented parallel to the x-direction or width direction of the cooking appliance or door. In this case, the axis of rotation is horizontally positioned.

[0008] The door is preferably detachable from the cooking chamber, allowing it to be disassembled and reassembled while detached. Alternatively, the door can also be disassembled and reassembled while installed in the cooking chamber. The window slat positioning device is particularly suitable for positioning and thus installing the inner and middle window slats onto the door. The door can also be disassembled again using the window slat positioning device. The window slat positioning device can also be referred to as an installation and removal device. Furthermore, the window slat positioning device can also be referred to as a window slat receiving part or a window slat receiving device.

[0009] The outer, inner, and intermediate windows are preferably at least partially transparent. The number of intermediate windows is, in principle, arbitrary. For example, one intermediate window can be provided. However, two or three intermediate windows can also be provided. When the intermediate windows are guided toward the outer windows, they are specifically placed on a window positioning device, whereby the window positioning device rotates about a rotation axis. The intermediate windows can be made of glass, sol-gel, polycarbonate, or similar materials. Alternatively, the intermediate windows can be constructed as observation baffles made of metal, non-ferrous metals, or plastic.

[0010] The window slat positioning device "encircles" the intermediate window slat, which specifically means that the window slat positioning device is engaged around the upper edge, lower edge, or side edge of the intermediate window slat. This means that the intermediate window slat is received in sections within the window slat positioning device. In particular, the window slat positioning device form-locks around the intermediate window slat. The form-locking connection is achieved by two connecting mating parts, in this case, the intermediate window slat and the window slat positioning device, engaging with each other or engaging from behind. The intermediate window slat can only be disengaged from the window slat positioning device by re-pivoting the window slat positioning device. This pivoting movement can be initiated, for example, by lifting the intermediate window slat from the door.

[0011] According to one embodiment, the window positioning device includes a spring element that preloads the window positioning device toward an initial position.

[0012] In the initial position, the spring element is almost slack or powerless. However, the spring element is minimally preloaded so that the window slat positioning device is held in the initial position. The window slat positioning device can be positioned from the initial position through one or more intermediate positions into the final position. With the door installed, the window slat positioning device is in its final state, with the inner window slat resting on the buffer element of the window slat positioning device. In the final state, the spring element is maximally preloaded. The spring element "spring-preloads" the window slat positioning device toward the initial position, which means that the window slat positioning device can be positioned from the initial position into the final position by the application of force, i.e., by the placement of the intermediate window slat. Once the force is no longer applied, that is, once the intermediate window slat is no longer placed on the window slat positioning device, the window slat positioning device automatically returns from the final position to the initial position. The spring element is in particular a helical torsion spring or a torsion spring. The spring element can also be a leaf spring. The spring element is particularly suitable for applying torque to a rotating shaft.

[0013] According to another embodiment, the door further includes a door bracket fixedly connected to the outer window panel.

[0014] As mentioned above, two door brackets are preferably provided. Specifically, the rotating shaft is located on one of the door brackets. Preferably, the door bracket is bonded to the outer window slat. This ensures a reliable connection between the door bracket and the outer window slat. Each door bracket can be equipped with a window slat positioning device. Preferably, the door bracket is made of plastic material. Alternatively, the door bracket can also be made of metal. For example, the door bracket is made of acrylonitrile-butadiene-styrene (ABS), especially fiber-reinforced ABS. Alternatively, any other plastic material can be used. By using plastic material for the door bracket, the door bracket can be manufactured cost-effectively as a plastic injection-molded component.

[0015] In another embodiment, the rotation axis is oriented parallel to the y-direction or the x-direction of the door.

[0016] In the first case, the rotation axis is arranged vertically. In the second case, the rotation axis is arranged horizontally. As mentioned earlier, the y-direction can also be referred to as the height direction, and the x-direction can also be referred to as the width direction.

[0017] In another embodiment, when at least one intermediate window pane is guided toward the outer window pane, the window pane positioning device pivots about a rotation axis such that the buffer element of the window pane positioning device moves such that the at least one intermediate window pane is arranged between the buffer element and the outer window pane, wherein the inner window pane is placed on the buffer element such that the buffer element is arranged between the at least one intermediate window pane and the inner window pane.

[0018] The buffer element advantageously achieves tolerance compensation during door assembly. The buffer element is pivoted such that the intermediate window is positioned between the buffer element and the outer window. That is, the buffer element performs a pivoting movement. The inner window is positioned on the buffer element in such a way that the buffer element is compressed.

[0019] In another embodiment, the window positioning device includes a plurality of manipulators, wherein at least one intermediate window is positioned on one of the manipulators as it is guided toward the outward window, such that the window positioning device pivots about a rotation axis.

[0020] The window positioning device pivots about a rotation axis by placing the intermediate window onto the corresponding control arm, wherein the spring element is tensioned.

[0021] In another embodiment, the buffer element is mounted on one of the other control arms.

[0022] Once the intermediate window is placed onto the aforementioned control arm, this other control arm pivots about the rotation axis. Preferably, two cushioning elements are provided on the other control arm, with the control arm arranged between the cushioning elements. The cushioning elements face the intermediate window and the inner window, respectively. Alternatively, only a single continuous cushioning element can be provided. The cushioning element can be made of, for example, thermoplastic elastomer (TPE), especially thermoplastic polyurethane (TPU). For example, the window positioning device can be a plastic injection molded component manufactured using a multi-component plastic injection molding process.

[0023] In another embodiment, the window positioning device includes a first manipulator, a second manipulator, and a third manipulator, wherein the manipulators are interconnected by means of a rotating shaft.

[0024] In other words, the window positioning device is preferably a one-piece or integral component. Here, "one-piece" or "integrated" means that the first, second, and third operating arms, together with the rotating shaft, form a common component and are not composed of separate components. As mentioned earlier, the window positioning device is preferably manufactured using a plastic injection molding method. The second operating arm is optional. It is only necessary when there is more than one intermediate window.

[0025] In another embodiment, the second manipulator includes a first buffer element and a second buffer element, wherein the second manipulator is disposed between the first buffer element and the second buffer element.

[0026] Alternatively, a single, continuous buffer element can be provided. Preferably, the first buffer element abuts against the first intermediate window panel of the door, and the second buffer element abuts against the second intermediate window panel of the door.

[0027] In another embodiment, the third manipulator includes a third buffer element and a fourth buffer element, wherein the third manipulator is arranged between the third buffer element and the fourth buffer element.

[0028] Alternatively, continuous buffer elements can be provided on the third control arm. The third buffer element abuts against the second intermediate window, and the fourth buffer element abuts against the inner window. In the case where only one intermediate window is provided, the third buffer element abuts against this intermediate window.

[0029] In another embodiment, the third buffer element includes an inlet ramp.

[0030] This allows for a simplified installation of the second intermediate window. Therefore, the second intermediate window can easily pass beside the third buffer element without colliding with it.

[0031] In another embodiment, the third buffer element abuts against at least one intermediate window, wherein the fourth buffer element abuts against an inner window.

[0032] In other words, the third and fourth buffer elements are arranged between the intermediate window and the inner window. As mentioned earlier, the third and fourth buffer elements can also include a common buffer element for the third operating arm. These buffer elements are preferably cylindrical in shape.

[0033] In another embodiment, the door includes a first intermediate window panel and a second intermediate window panel, wherein the two intermediate window panels are arranged between an inner window panel and an outer window panel.

[0034] The number of intermediate windows is arbitrary in principle. It is also possible to set only one intermediate window. Furthermore, it is also possible to set more than two intermediate windows, such as three intermediate windows.

[0035] In another embodiment, the first buffer element abuts against the first intermediate window, wherein the second buffer element abuts against the second intermediate window.

[0036] In other words, the first and second buffer elements are arranged between the first and second intermediate windows. As mentioned earlier, the first and second buffer elements can also form a common, continuous buffer element for the second control arm.

[0037] In addition, a household cooking appliance having a cooking chamber and a door fixed to the cooking chamber is proposed.

[0038] As mentioned earlier, the household cooking appliance can be a stove, oven, microwave oven combination, double oven, etc. "Fixed" here means that the door is connected to the cooking chamber, for example, in a manner that allows it to pivot vertically or horizontally. Alternatively, the door can also be mounted on a baking rack that can be removed from the cooking chamber. In this case, the door is not pivotally supported on the cooking chamber, but rather can move or move linearly relative to the cooking chamber. However, the door can perform any of these arbitrary movements when it is open.

[0039] Other possible implementations of the door and / or household cooking appliance also include combinations of features or implementations not explicitly mentioned in the foregoing or following descriptions of the embodiments. Here, those skilled in the art may also add individual aspects as improvements or supplements to the corresponding basic forms of the door and / or household cooking appliance.

[0049] Figure 9 It shows according to Figure 8 View IX. Detailed Implementation

[0050] In the accompanying drawings, unless otherwise specified, the same or functionally equivalent elements are given the same reference numerals.

[0051] Figure 1A schematic perspective view of one embodiment of a household cooking appliance 1 is shown. The household cooking appliance 1 can be a stove, oven, microwave oven combination, double oven, etc. The household cooking appliance 1 has a cooking chamber 2, which can be closed by means of a door 3. The cooking chamber 2 can also be referred to as a muffle oven or oven muffler. The cooking chamber 2 can be arranged inside the housing of the household cooking appliance 1. The door 3 is... Figure 1 The door 3 is shown in the closed position. It can be closed or opened by rotating around a rotation axis provided at the lower end or lower edge 4 of the door 3. Alternatively, the door 3 can be fixed to the cooking chamber 2 from the side. Furthermore, the door 3 can be mounted on a baking rack that can be pulled out of the cooking chamber 2. However, the movement of the door 3 when it is open can be arbitrarily selected. That is, the door 3 can, in principle, perform any arbitrary movement when it is open.

[0052] A handle 6 can be provided on the upper section or upper edge 5 of the door 3. The cooking chamber 2 has a bottom 7, a top cover 8 opposite to the bottom 7, a rear wall 9 opposite to the closed door 3, and two side walls 10 and 11 opposite to each other. The cooking chamber 2 is preferably square or cubic. The cooking chamber 2 can be made of metal, especially steel plate.

[0053] Furthermore, the household cooking appliance 1 includes operating ball handles 13 and 14 disposed on a switch panel or control panel 12. The operating ball handles 13 and 14 may, for example, be rotatable. A control device 15, shown only schematically, may be disposed on the back of the control panel 12 for controlling the household cooking appliance 1. The control device 15 may be an adjustment and / or control device. Additionally, a display 16 may be disposed on the control panel 12. The operating status of the household cooking appliance 1 can be displayed by means of the display 16. For example, the temperature set by means of one of the operating ball handles 13 and 14 can be displayed by means of the display 16.

[0054] The household cooking appliance 1 is pyrolytic. That is, the cooking chamber 2 can be heated by a correspondingly high temperature. Dirt adhering to the inner surface of the cooking chamber 2 and to the door 3 is carbonized here, causing the dirt to either fall off on its own or be easily removed. However, this pyrolytic function is not mandatory. The door 3 is a ventilation door. That is, airflow is directed through the door 3.

[0055] The household cooking appliance 1 or door 3 is equipped with a coordinate system having a width direction (x-direction), a height direction (y-direction), and a depth direction (z-direction). The x, y, and z directions are oriented perpendicularly to each other. The door 3 includes an outer window 17, which lies in a plane opened by the x and y directions. A first door bracket 18 and a second door bracket 19 are mounted on the outer window 17 on its back side, i.e., facing the cooking chamber 2. The door brackets 18 and 19 extend along the y-direction when the door 3 is closed. The door brackets 18 and 19 are preferably glued to the outer window 17 on their back side. The door brackets 18 and 19 are made of plastic. Hinges (not shown) can be mounted on the door brackets 18 and 19, allowing the door 3 to be pivotally fixed to the cooking chamber 2.

[0056] Figure 2 A schematic partial perspective view of one embodiment of the door 3 as mentioned above is shown. Figure 3 It shows according to Figure 2 View III. See also below. Figure 2 and 3 .

[0057] As mentioned above, the door 3 includes an outer window panel 17, on which door brackets 18 and 19 are attached to the back. Figure 2 and 3 Only the first door support 18 is shown. Besides the outer window 17, the door 3 includes an inner window 20 facing the cooking chamber 2. A first intermediate window 21 and a second intermediate window 22 are disposed between the outer window 17 and the inner window 20. The number of intermediate windows 21 and 22 is arbitrary in principle. The first intermediate window 21 is positioned closer to the outer window 17 than the second intermediate window 22. Correspondingly, the second intermediate window 22 is positioned closer to the inner window 20 than the first intermediate window 21. The inner window 20 is held by a locking device 23 that can move along the first door support 18. The locking device 23 can also be referred to as a sliding cover.

[0058] During the operation of the household cooking appliance 1, especially during pyrolysis operation, air circulates between the outer window slat 17 and the first intermediate window slat 21, and between the first intermediate window slat 21 and the second intermediate window slat 22. An upright air cushion is provided between the second intermediate window slat 22 and the inner window slat 20. This air cushion serves as insulation. However, this upright air cushion is not mandatory. Dirt may accumulate on the intermediate window slats 21, 22, the inner window slat 20, and / or the outer window slat 17. Therefore, as will be explained below, the user can remove the inner window slat 20 and the intermediate window slats 21, 22 from the door 3 for cleaning.

[0059] Figure 4 It shows according to Figure 2 Another schematic partial perspective view of door 3. Figure 5 It shows according to Figure 4 View V. See also the following: Figure 4 and 5 .

[0060] For the installation and removal of the inner window slats 20 and the intermediate window slats 21, 22, the door 3 includes a window slat positioning device 24. The window slat positioning device 24 is adapted to position and install the inner window slats 20 and the intermediate window slats 21, 22 onto the door 3. The door 3 can also be removed again by means of the window slat positioning device 24. The window slat positioning device 24 can also be referred to as an installation and removal device. The window slat positioning device 24 can also be referred to as a window slat receiving part or a window slat receiving device. The window slat positioning device 24 is fixedly connected to the door 3, and particularly fixedly connected to the first door bracket 18. Preferably, such a window slat positioning device 24 is provided on each door bracket 18, 19. However, only the window slat positioning device 24 will be discussed below.

[0061] The window slat positioning device 24 includes a first operating arm 25, a second operating arm 26, and a third operating arm 27. The operating arms 25 to 27 are fixedly connected to each other. The window slat positioning device 24 also includes a rotation shaft 28, about which the window slat positioning device 24 is supported on the first door bracket 18. However, the window slat positioning device 24 need not be rotatably supported on the first door profile 18. The window slat positioning device 24 can also be supported on any other component of the door 3 about the rotation shaft 28. The operating arms 25 to 27 are fixedly connected to the rotation shaft 28. In particular, the operating arms 25 to 27 and the rotation shaft 28 form an integral component. "Integral" or "one-piece" here means that the window slat positioning device 24 is not composed of multiple individual components, but rather the operating arms 25 to 27 and the rotation shaft 28 form a common component.

[0062] In particular, the control arms 25 to 27 and the rotating shaft 28 form a component of uniform material. "Uniform material" here means that the control arms 25 to 27 and the rotating shaft 28 are continuously made of the same material. Alternatively, the third control arm 27 can also be made of other materials, especially silicone rubber or other soft components. For example, the window positioning device 24 is a plastic injection-molded component. The first control arm 25 and the second control arm 26 are positioned on the rotating shaft 28 such that the control arms 25, 26, in accordance with... Figure 5 In the view, it forms a U-shaped or C-shaped geometry. Viewed along the rotation axis 28, the third control arm 27 is positioned next to the control arms 25 and 26.

[0063] The second control arm 26 includes a first buffer element 29 facing the first control arm 25 and a second buffer element 30 facing away from the first control arm 25. The buffer elements 29 and 30 are square or block-shaped. The second control arm 26 is arranged between the buffer elements 29 and 30. Alternatively, a single, continuous buffer element can be used instead of two buffer elements 29 and 30.

[0064] The cushioning elements 29 and 30 can be made of a different material than the second operating arm 26. For example, the cushioning elements 29 and 30 can be made of thermoplastic elastomer (TPE), especially thermoplastic polyurethane (TPU). For this purpose, the window positioning device 24 can be manufactured, for example, by means of a two-component plastic injection molding method. The third operating arm 27 is provided with a third cushioning element 31 facing the second operating arm 26 and a fourth cushioning element 32 facing away from the second operating arm 26. The cushioning elements 31 and 32 can be made of a different material than the third operating arm 27. For example, the cushioning elements 31 and 32 can be made of TPE, especially TPU. Alternatively, a single, continuous cushioning element can be provided instead of two cushioning elements 31 and 32. An inlet ramp 33 is provided on the third cushioning element 31. The cushioning elements 29 to 32 can also be made of silicone rubber, for example, so-called liquid silicone rubber (LSR), HTV silicone, or RTV silicone. The cushioning elements 29 to 32 act as spacer pads. Therefore, the buffer elements 29 to 32 can also be referred to as spacer pads or spacer pad elements.

[0065] The window slat positioning device 24 is equipped with a spring element 34, in which the rotating shaft 28 is received at least in sections. The spring element 34 can be part of the window slat positioning device 24. The spring element 34 can be a coil spring or a leaf spring. Specifically, the spring element 34 is a coil torsion spring. That is, the spring element 34 can generate torque acting on the rotating shaft 28. The spring element 34 preloads the window slat positioning device 24 relative to the first door bracket 18 such that the window slat positioning device 24 remains in place. Figure 4 and Figure 5 The spring element 34 is nearly relaxed in the initial position AP. However, the spring element 34 has minimal preload in the initial position AP, causing the window slat positioning device 24 to remain in the initial position AP. A support section 35 is provided on the first door bracket 18, on which the first intermediate window slat 21 can be placed.

[0066] Figure 6 Another schematic partial perspective view of the door 3 is shown. Figure 7 It shows according to Figure 6 View VII. Figure 8 Another schematic partial perspective view of the door 3 is shown. Figure 9 It shows according to Figure 8 View IX. The following uses... Figures 2 to 9 To explain the functionality of the window positioning device 24.

[0067] First, the window positioning device 24 is in Figure 4 and 5 The initial position AP is shown in the diagram. (As in...) Figure 6 and 7 As shown, the first intermediate window 21 is introduced along the introduction direction E toward the outer window 17. Here, the first intermediate window 21 abuts against the first operating arm 25, thereby the window positioning device 24 moves from the outer window 17... Figure 4 and 5 The initial position AP shown is twisted to in Figure 6 and 7 The first intermediate window slat 21 is positioned in the middle position ZP shown and is held in place here. Here, the spring element 34 is tensioned. Here, the window slat positioning device 24 is rotated counterclockwise until the first intermediate window slat 21 abuts against the support section 35.

[0068] Next, as in Figure 8 and 9 As shown, the second intermediate window 22 is introduced along the introduction direction E toward the outer window 17. The introduction of the second intermediate window 22 is facilitated by the introduction ramp 33. During the introduction of the second intermediate window 22, it is positioned on the second buffer element 30 of the second operating arm 26 such that the window positioning device 24 moves from the intermediate position ZP to the final position EP, in which the second operating arm 26 is positioned between the first intermediate window 14 and the second intermediate plate 22. The second intermediate window 22 is also engaged by the window positioning device 24 when it is moved from the intermediate position ZP to the final position EP. Here, the first buffer element 29 abuts against the first intermediate window 21, and the second buffer element 30 abuts against the second intermediate window 22. Here, the buffer elements 29 and 30 can be compressed. Furthermore, the third operating arm 27 is also pivoted such that the second intermediate window 22 is positioned between the second operating arm 26 and the third operating arm 27.

[0069] Finally, as in Figure 2 and 3As shown, the inner window slat 20 is placed on the third operating arm 27, and more particularly on the fourth buffer element 32. Here, the third operating arm 27 is elastically deformable such that the third buffer element 31 abuts against the second intermediate window slat 22 and the fourth buffer element 32 abuts against the inner window slat 20. Here, the buffer elements 31 and 32 can be compressed. Here, the third operating arm 27 is optional. The function of the third operating arm 27 is to receive and position the buffer elements 31 and 32 between the second intermediate window slat 22 and the inner window slat 20. During the installation of the inner window slat 20, the buffer elements 31 and 32 are compressed. After the inner window slat 20 is installed, the locking device 23 is pushed into the first door bracket 18, such that the locking device 23 secures the inner window slat 20 and presses it against the fourth buffer element 32. Here, the locking device 23 partially surrounds the inner window slat 20.

[0070] The advantages of the window slat positioning device 24 are explained below. The window slat positioning device 24 is fixedly mounted on the door 3 or on the corresponding door brackets 18 and 19. Therefore, the window slat positioning device 24 is inextricably linked to the door 3. The integration of the spring element 34 ensures that the window slat positioning device 24 returns to its initial position AP. The function of the window slat positioning device 24 is independent of the top panel or upper sealing strip of the door 3. No tools are required for the removal and installation of the inner window slat 20 and the intermediate window slats 21 and 22.

[0071] The window slat positioning device 24 can be made of different materials, thereby allowing adjustment of the cushioning characteristics of the buffer elements 29 to 32. An guide ramp 33 is provided on the third buffer element 31, which facilitates the installation of the second intermediate window slat 22. The window slat positioning device 24 can be used not only when the door 3 is installed on the household cooking appliance 1 but also when the door 3 is removed from the household cooking appliance 1. The window slat positioning device 24 can also be made of metal instead of plastic. The window slat positioning device 24 is inextricably linked to the corresponding door brackets 18, 19. Large tolerance compensation can be achieved by means of the flexible and deformable buffer elements 29 to 32. Furthermore, the door 3 can be opened with just one hand. Other functions, such as window slat inspection, can be combined with the window slat positioning device 24.

[0072] Although the invention has been described with reference to embodiments, it can be modified in a variety of ways.
