Description

[0001] The present invention relates to a household appliance with a treatment chamber that can be closed by a door and with a filling device for filling an operating liquid or an operating powder, which can be introduced into the treatment chamber in an operating mode of the household appliance, treated or untreated.

[0002] Such a household appliance is known from WO 2009 / 027052 A2. This known household appliance has a treatment chamber that can be closed by a door. The treatment chamber is bounded by a frame. A filling device is provided for a flow-conducting connection to an external container holding the operating fluid or powder. The filling device is arranged on the frame, and the opening for filling the operating fluid or powder is accessible at least when the door is fully open and is covered by the door when it is closed. The filling device, or a nozzle of the filling device, is movable back and forth between a rest position in which the nozzle rests against the frame and a filling position in which the nozzle protrudes from the frame with its free end.The spout is bent at a right angle at its upper end and is pivotally clamped between the upper and lower parts of a holder. This allows the spout to be fixed in any position by the frictional forces acting between the spout and the holder. This enables the lower filling end of the spout to be swung out when the treatment room door is open, before an external container is brought in. The frictional forces are intended to ensure that the spout remains in this position after being swung out. This well-known household device functions satisfactorily. However, it has been observed that in isolated cases, disturbing noises can occur when the spout is swung out. Furthermore, it is possible that the frictional forces may decrease over time to such an extent that effective clamping of the spout can no longer be guaranteed.Then, after being swung out, the nozzle no longer retains its filling position but slides back into its resting position, which makes operation more difficult.

[0003] It is therefore the object of the present invention to provide a household appliance with which an improved function can be achieved and in which at least one of the aforementioned disadvantages is eliminated.

[0004] This problem is solved by a household appliance having the features of claim 1. Preferred embodiments of the invention are the subject of the dependent claims. Further advantages and features of the present invention will become apparent from the general description and the description of exemplary embodiments.

[0005] A household appliance according to the invention has a treatment chamber that can be closed by a door. The household appliance includes a filling device for filling it with an operating medium. For the purposes of this invention, an operating medium is understood to be an operating liquid or an operating powder. The operating medium, and in particular an operating liquid or an operating powder, can be introduced into the treatment chamber in one operating mode of the household appliance, either treated or untreated. The opening of the treatment chamber, which can be closed by the door, is bounded by at least one frame part. The filling device is designed to be suitable for a flow-conducting connection with an external container containing the operating medium, and in particular the operating liquid or the operating powder. The filling device is arranged on the frame part.An opening in the filling device for filling the operating medium, and in particular the operating liquid or operating powder, is accessible at least when the door is fully open and is covered by the door when it is closed. The filling device has a pivoting mechanism with a nozzle, wherein the pivoting mechanism can be pivoted back and forth along at least one pivot path between a rest position, in which the nozzle essentially rests against the frame part, and a filling position, in which the nozzle protrudes from the frame part at least with its free end. At least one clamping profile is associated with the pivoting mechanism, which clamping profile acts on the pivoting mechanism within a defined angular range of the pivot path to ensure a defined separation between the rest position and the filling position.

[0006] The household appliance according to the invention has many advantages. A significant advantage of the household appliance according to the invention is that the spout of the filling device can be moved into defined positions, wherein the clamping profile, or at least one clamping profile, acts on the swivel mechanism within a defined angular range of the swivel path, thus ensuring a defined separation between the rest position and the filling position. In contrast to the known prior art, the clamping profile does not act on the spout or the swivel mechanism at any arbitrary angular position, but rather the profile acts on the swivel mechanism within precisely a defined angular range of the swivel path between the rest position and the filling position, while the swivel mechanism is not clamped by the clamping profile in the rest position and / or the filling position and is preferably unaffected by the clamping profile.

[0007] The clamping profile creates a defined separation, thereby achieving, in accordance with the present invention, at least a tactilely perceptible separation of the rest position from the filling position during the pivoting movement. The clamping profile provides a defined angular position for filling. In the filling position, the pivoting mechanism and thus also the spout are in a secured position, preventing automatic pivoting back, for example, due to gravity. In particular, the clamping profile prevents automatic pivoting back. The clamping profile preferably acts as a stop.

[0008] The invention advantageously provides a household appliance in which the spout of the filling device can be pivoted without disturbing noises. Furthermore, the spout remains in the position to which it has been moved. This leaves both hands free for the user during operation. With the prior art, the spout does not remain in the intended position if the clamping force is too weak, and excessive clamping can sometimes result in noticeable grinding noises during use. The present invention provides a defined separation between the rest position and the filling position. The clamping profile does not constantly exert full force on the pivoting mechanism. The set clamping conditions can also be reliably maintained over the long term.

[0009] The clamping profile ensures a defined and tactilely perceptible separation between the rest position and the filling position during the swiveling movement. In the filling position, a secure position is provided, preventing any automatic swiveling back.

[0010] In preferred embodiments, the clamping profile is attached to or formed on the filling device. It is also possible for the clamping profile to be attached as a separate part, for example, to the frame component. For assembly purposes, it is simpler if the clamping profile is attached directly to the filling device or, in particular, formed on it.

[0011] Preferably, the clamping profile comprises at least one lateral retaining cam. In particular, it is also possible for the clamping profile to comprise at least two lateral retaining cams, which act symmetrically and on both sides of the pivoting mechanism.

[0012] In advantageous embodiments, the clamping profile acts on the nozzle within a defined angular range. The nozzle, as part of the swivel mechanism, is pivoted back and forth at least between the rest position and the filling position during the swiveling movement. It is therefore advantageous if the clamping profile acts on the nozzle within this defined angular range. However, it is also possible for the clamping profile to act on other parts or components of the swivel mechanism.

[0013] Preferably, the pivoting mechanism is pivotably mounted on a bearing, particularly on the filling device. The nozzle can be pivotally mounted on the bearing by at least one bearing pin. The bearing pin can be designed as a through bearing bolt that passes through the nozzle and its conduit. Alternatively, the bearing pin can be designed as a bearing cam that projects (only) laterally and, in particular, transversely from the nozzle. It is especially preferred if two laterally projecting bearing cams are provided or formed on the nozzle, while the conduit for the operating medium remains unobstructed.

[0014] In all embodiments, it is preferred that the bearing comprises at least one bearing shell. It is also possible that the bearing is formed by two laterally spaced bearing shells, on which the bearing pin is pivotably mounted on both sides.

[0015] It is possible and preferred that the clamping profile, or at least one, is formed on the bearing. In such an embodiment, at least one radially inwardly projecting clamping unit is provided on the bearing, and at least one radially outwardly projecting clamping cam is provided on the bearing pin. The clamping unit and the clamping cam engage with each other during the pivoting movement of the pivoting mechanism, so that the clamping profile clamps the clamping mechanism. By selecting suitable materials for the clamping unit and the clamping cam and / or the retaining cam of the clamping profile(s), a suitable force can be set that enables reliable separation of the rest position from the filling position and whose clamping force is maintained, at least substantially, even after numerous uses.

[0016] Preferably, the nozzle is (at least) substantially rod-shaped. Preferably, the nozzle has no kink or significant bends and is, in particular, at least substantially straight.

[0017] In advantageous embodiments, a flexible hose is connected to the end of the nozzle opposite the (filling) opening. The operating medium (in particular an operating liquid or an operating powder) is transported further through the flexible hose.

[0018] In all embodiments, it is possible and preferred that a clamping profile comprises several clamping units in different angular ranges of the swivel path, or that two or more clamping profiles are arranged in different angular ranges of the swivel path. In both cases, this provides several defined grid positions along the swivel path. Various swivel positions can be defined. Clamping elements of the clamping profile, such as retaining cams, etc., can be mounted in a guide.

[0019] The invention further has the advantage that a filling device can be accommodated in a (tightly) limited space, which houses and guides the pivoting mechanism with the pivoting nozzle. In simple cases, the working and resting positions of the nozzle can be defined by plastic cams in a guide. The pivoting movement is silent.

[0020] It is possible to define not only a rest position and a filling position, but also several different filling positions along the swivel path.

[0021] The invention enables a visually unobtrusive arrangement of the filling device on the household appliance. The filling device, which is generally not required except during the filling process, recedes into the background both visually and in terms of user operation. This allows for a functionally and structurally simpler separation of electrical and liquid-carrying components. The filling device and its opening are automatically covered by the closed door of the treatment chamber during operation of the household appliance.

[0022] Preferably, the filling device and its nozzle are designed and arranged such that the nozzle automatically moves from the filling position to the resting position when the door is closed. This ensures that the nozzle cannot be pinched between the door and the body of the appliance, even if it is operated carelessly.

[0023] In all embodiments, it is possible to arrange an elastic buffer element surrounding the opening of the filling device at its free end. Such an elastic buffer element can be made of suitable materials known to those skilled in the art. This ensures a dampened, material-friendly, and quiet contact of the filling device with the door when it is closed.

[0024] In all embodiments, it is preferred that the swivel range is limited by end stops. The end stops can be located adjacent to the rest position and the filling position. End stops effectively prevent movement beyond these two end positions.

[0025] In all designs, the nozzle is limited or fixed in the filling position in such a way that a change in position does not occur solely due to the force of gravity.

[0026] It is particularly preferred that a household appliance according to the invention is designed as a cooking appliance, and in particular as an oven. In particular, the cooking appliance or oven is a combination appliance in which several different heating methods are provided, depending on the selected operating mode or program. Preferably, radiant heaters designed for top and bottom heat can be used. In particular, saturated steam can also be supplied. It is equally preferred that energy can be supplied via electromagnetic radiation such as microwave radiation or electromagnetic radiation in other frequency ranges, or the like. Other known heating methods, such as contact heating, as well as other forms of steam, such as superheated steam, are also possible as an alternative or in addition to the aforementioned heating methods.
