Description

closing device

The invention is based on a closing device, in particular a household appliance closing device, for movably supporting a door on a functional body according to the preamble of claim 1.

It is known from EP 1 055 881 A2 discloses a closing device in the form of a domestic appliance hinge device for pivotally mounting a door to an oven, which generates a force unit which generates in an open position of the door a pulling force urging the door in the closing direction, as well as a Damping unit which serves to damp a movement of the door relative to the oven.

The object of the invention is in particular to provide a generic Schließvor- direction with a power unit and a damping unit, in which a compact design can be achieved.

The object is achieved by the features of claim 1, while advantageous embodiments and modifications of the invention, the subclaims can be taken.

The invention is based on a closing device, in particular a household appliance closing device, for the movable, in particular pivotable, mounting of a door on a functional body between a closing position closing a functional body space and at least one opening position, with a first unit designed as a force unit for generating a force at least in an open position the door loaded, and a second, designed as a damping unit unit, which is intended to damp at least a part of a movement of the door relative to the functional body.

It is proposed that one of the units is at least partially incorporated in the other unit. This can be advantageously saved space. In particular, an existing, formed by one of the units space for introducing the second unit. Particularly advantageously, in the case of an existing closing device which has a power unit, a damping unit can additionally be used, wherein the dimensions of the closing device can be maintained. Furthermore, this insertion can take place in different closing devices, which differ in size and weight, whereby a particularly high flexibility in the use can be achieved. An "opening position" of the door is to be understood as meaning, in particular, a position of the door relative to the functional body that differs from the closed position, in which case the opening position may be an end opening position at which the movement of the door is locked or an intermediate opening position between For the movable mounting of the door on the functional body, the closing device preferably has a means, such as in the form of a hinge unit, which serves to hold the door on the functional body and additionally a degree of freedom to a movement, in particular a pivoting movement of the Door relative to the functional body, provides.

Preferably, the door is loaded at least in an opening position by the force generated by the power unit in the direction of the closed position. In the case of a pivotable mounting of the door, a "force that loads the door in the direction of the closed position" is to be understood in particular to mean a force which generates a torque relative to a pivot axis of the door, which tends to pivot the door into its closed position. Further, the force generated by the power unit may serve as a balancing force tending to produce a torque balancing torque generated by the door weight, In particular, the door may have a stable opening position by the power unit in which both torques cancel each other out. The torque generated by the power unit contributes, in particular, as a driving force during a closing movement of the door, in particular in an angular range between the stable opening position and the closing position In this connection, it is advantageous, if the damping unit is provided, for at least a part l a closing movement of the door relative to the functional body to dampen.

A "damping of a movement of the door" should be understood in particular a process in which a kinetic energy of the door is dissipated by at least one damping means of the damping unit to a speed reduction of Door relative to the functional body to achieve. "Provided" is to be understood in particular to be specially designed or specially equipped.

A "unit which is at least partially incorporated in another unit" is to be understood as meaning, in particular, a unit which is at least partly arranged or accommodated in a space formed by the other unit, in the inserted state of one of the units in the other unit Preferably, the introduced unit is at least partially, preferably completely, enclosed by the other unit. [0009] In a mounting of the locking device, the inserted condition is achieved, in particular, by the inserted unit engaging in the other unit Preferably, this engagement in an engagement direction, which is aligned parallel to the longitudinal direction of the female unit.

In order to achieve a particularly high space saving, it is proposed that at least a majority of the introduced unit is arranged in a space formed by the other unit. A "large part of a unit" is to be understood as meaning, in particular, a part of the unit which forms at least 50%, advantageously 70% and preferably 80% of the total mass of the unit If the unit is designed as an elongate unit, it may also form part of the unit below be understood, whose length has at least 50%, preferably 70% and preferably 80% of the total length of the unit.

It is particularly proposed that the power unit is designed as a spring, whereby existing and inexpensive means can be used.

In a preferred embodiment of the invention it is proposed that the damping unit is at least partially introduced into the power unit. As a result, existing and common power units and damping units can be used. This is particularly suitable when the power unit as a spring, in particular as a tension spring, e.g. as a helical compression spring is formed. Here, the damping unit is advantageously at least partially introduced in an inner space of the power unit formed by spring windings.

A structurally simple construction can also be achieved if the damping unit has a damping means and an actuating means, which leads to an actuation the damping means is provided in a damping operation, and the damping means is arranged completely in a space formed by the power unit. An "actuating means for actuating the damping means" is to be understood in particular as a means movable relative to the damping means, wherein relative to the damping means relative movement of the actuating means, which is preferably in operative connection with a movement transmission unit for transmitting a movement of the door, a dissipation of the kinetic energy Door causes.

It is also proposed that the damping unit and the power unit are arranged coaxially with each other, whereby an optimal utilization of an existing space can be achieved. By "two units coaxial with each other" it is to be understood, in particular, that the units each have a characteristic axis, such as a symmetry and / or longitudinal axis, and that the characteristic axes of the units coincide.

Preferably, the locking device has a door body of the door, in which the damping unit is mounted. By the door-side arrangement of the damping unit can advantageously be achieved a particularly simple and compact mechanism for transmitting a movement of the door to the damping unit. This can be achieved particularly easily if the door body is designed as a hinge housing in which the damping unit and the power unit are arranged.

A particularly high degree of user comfort can be achieved if the door is pivotable from the closed position into an end opening position with a maximum opening angle, wherein the damping unit defines an intermediate opening position between the closing position and the end opening position, in which the damping unit is switched on when closing from the end opening position , The intermediate opening position of the door corresponds in particular to a position of the door in which a means for direct or indirect coupling of the damping unit with a pivoting movement of the door leading pivot means in a closing operation from the Endöffnungsposition comes into operative connection with the damping unit. Here, this position is preferably given by a special embodiment of the damping unit, such as by a convenient choice of dimensions. It is also proposed that the damping unit has a housing for receiving a damping medium, whereby existing and robust damping means for the damping unit can be used. In particular, the damping medium is formed as a fluid, ie gas or liquid.

In a development of the invention, it is proposed that the closing device has a movement transmission unit which is provided to transmit a movement of the door relative to the functional body to the force unit and the damping unit. By these agreed functions of the motion transmission unit, the space can be further reduced. Particularly advantageously, the movement transmission unit has an integral means, which cooperates both with the force unit for varying the force generated and with the damping unit for achieving a damping effect.

In this connection, it is proposed that the damping unit has a damping means, an actuating means, which is provided for an actuation of the damping means in a damping operation, and a coupling means for coupling to the movement transmission unit, which adjoins the actuating means introduced in the power unit. As a result, an optimal use of an existing space can be achieved. This can be achieved in a structurally simple manner if the coupling means has a slot in which a means of the motion transmission unit is guided.

Furthermore, further components can be saved if the closing device has a holding means for holding the power unit, which serves as a support means for supporting the damping unit in a damping operation.

The locking device according to the invention is particularly suitable for use in household appliances, in which a space provided for a closing device is typically to be kept low. By means of the closing device according to the invention, an increase in the ease of use can be achieved by the use of a damping unit, wherein an additional installation space can be dispensed with and the use of components of standardized dimensions can be maintained. Further advantages emerge from the following description of the drawing. In the drawings, embodiments of the invention are shown. The drawing, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into meaningful further combinations.

2 shows a detailed view of the door pivotally mounted on a functional body of the household appliance with a closing device, and FIG. 3 shows a hinge unit of the closing device with a force unit and a damping unit incorporated in the force unit.

FIG. 1 shows a domestic appliance 10 embodied as a cooking appliance in a front view, which has a baking oven muffle designed as a functional body 12. The functional body 12 forms a functional body space 14, which is designed as a cooking chamber. The design of the domestic appliance 10 as a cooking appliance is exemplary. In a further embodiment, the domestic appliance 10 can be, for example, a dishwasher with a functional body 12, which forms a functional body space 14 as a washing compartment. The domestic appliance 10 furthermore has a door device 16, which comprises a door 18 with a door main body 20 and a closing device 22. The closing device 22 is provided for the pivotable mounting of the door main body 20 on the functional body 12 between a closing position (shown in FIG. 1) closing the functional body space 14 and a substantially horizontal end opening position (see FIG. 2). For this purpose, the closing device 22 on two hinge units 24.1, 24.2, which are attached to the door base 20. The hinge units 24.1, 24.2 are arranged in the lateral areas of the door 18 on both sides of the feed opening of the functional body space 14. They are shown schematically in FIG. 1 by dashed lines and are shown in greater detail with reference to FIGS. 2 and 3. In the description of Figures 1 and 2, the terms "up", "down", "side", etc., refer to the basic installation position of the functional body 12 when the domestic appliance 10 is used under normal or prescribed conditions. Front "," Front "," Rear "etc. on a consideration of the domestic appliance 10 as shown in FIG. FIG. 2 shows the functional body 12 and the door device 16 in a sectional view along the line M-II in FIG. 1 in the end opening position of the door 18. In particular, the closing device 22 is shown, which has the hinge unit 24.1. The following text is limited to the description of the hinge unit 24.1 to avoid repetition. It also applies to the construction of the hinge unit 24.2. The hinge unit 24.1 has a hinge housing. This is designed as a door body 26 which is rigidly coupled to the door base 20. The door body 26 is formed as a cuboidal, elongate component, which forms a receiving space in which further elements of the closing device 22 are accommodated. These further elements are shown in the detailed representation of FIG. The main extension direction 27 of the door body 26 is aligned vertically in the closed position of the door 18 (FIG. 1) and substantially horizontally in the end opening position (FIG. 2). The main extension direction 27 and the vertical direction V are shown schematically in the figures. The door 18 has a door front surface 28 which, in the closed position, covers the hinge units 24 from the front (see FIG. 1). The hinge unit 24.1 further comprises a pivoting element 30, which is pivotally mounted on the one hand on the housing formed as a hinge body 26 about a pivot axis 32 and on the other hand secured to the functional body 12 and is rigidly coupled thereto. When the door is actuated by an operator, the door 18 pivots about the pivot axis 32, wherein an opening angle W characterizing the position of the door 18 between 0 ° (closing position of FIG. 1) and a maximum angle W _max (end opening position of FIG 2) can be varied, wherein W _{max is} about 90 °.

In Figure 3, the closure device 22 is shown with the hinge unit 24.1 separated from the functional body 12 in a perspective view. It can be seen as a hinge housing formed door body 26, which has a U-shaped profile. For a clear representation of the arranged in the door body 26 elements a section is performed in a housing wall. Furthermore, the pivoting element 30, which is likewise shown in FIG. 2, can be seen, which is mounted so as to be pivotable relative to the door body 26 by means of the pivot axis 32 mounted on the door body 26. It is shown in Figure 3 in a position relative to the door body 26, which corresponds to the closed position of the door 18 of Figure 1. Starting from this position, it can be pivoted relative to the door body 26 until its main direction of extension coincides with the main extension direction 27 of the door body 26, the door 18 being in its end opening position. tion (Figure 2) is arranged. In the description of FIG. 3, the terms "up" and "down" are defined in relation to the arrangement of the pivot axis 32 in the door body 26. Here, the lower portion of the door body 26 corresponds to the region of the door body 26 in which the pivot axis 32 is arranged. The pivoting element 30 is in operative connection with a connecting rod element 34. By a pivoting movement of the pivoting element 30 relative to the door body 26, according to a known principle, a translational movement of the connecting rod element 34 occurs parallel to the main extension direction 27 of the door body 26 along an inner wall of the door body 26 is executed. During an opening movement of the door 18, the coupling element with the pivoting element 30 moves the connecting rod element 34 in the direction of the pivot axis 32, and during a closing movement of the door 18, it is moved away from the pivot axis 32.

The closing device 22 also has a force unit 36 designed as a helical spring, which is arranged in the hinge unit 24.1, specifically in the door body 26 of the hinge unit 24.1 designed as a hinge housing. This has an axis of symmetry 38, which corresponds in particular to the spring longitudinal axis about which the spring coil is wound, and is aligned in the main extension direction 27 of the door body 26. This force unit 36 is intended to generate a force which loads the door 18 in the direction of the closed position, at least in an opening position. For this purpose, the power unit 36 at its upper, the pivot axis 32 opposite end to the door body 26 is rigid and connected at its lower, the pivot axis 32 facing the end with the connecting rod 34 by a means 54 described in more detail below such that movement of the connecting rod 34 causes a tensioning of the power unit 36 in the direction of the pivot axis 32. In this sense, the pivot member 30, the pivot axis 32, the connecting rod member 34 and the means serve as Bewegungsübertragungs- 40, which is intended to transmit a movement of the door 18 relative to the functional body 12 to the power unit 36, wherein a change in Force generated by the force unit 36 can be achieved by this movement. The provision of such a motion transmission unit 40 for cooperation with the force unit 36 by means which appears to the skilled person as meaningful is conceivable. During an opening movement or a closing movement of the door 18, the movement transfer unit 40 causes an increase or a reduction in the force generated by the force unit 36. The force unit 36 in an opening position of the door 18 tends to guide the connecting rod 34 away from the pivot axis 32, whereby a torque for assisting via the pivot axis 32 and the pivoting element 30 is provided. tion of a closing movement of the door 18 is generated. Further, by the power unit 36, the weight of the door can be balanced. In particular, a stable opening position of the door 18 can be achieved, in which the torque generated by the power unit 36 balances the torque resulting from the door weight. This stable opening position is achieved, for example, at the opening angle W = approximately 45 °.

In order to avoid an impact of the door 18 on the functional body 12 at the end of the closing movement, the closing device 22 has a damping unit 42, which is provided to damp at least a part of the closing movement of the door 18. The damping unit 42, which, like the power unit 36, is arranged in the hinge unit 24.1, namely in the door body 26 of the hinge unit 24.1 designed as a hinge housing, has a damping means 44 with a housing 46, in which a damping medium, such as a gas or a liquid is absorbed. In particular, in the embodiment shown, the damping medium is designed as an oil by way of example. The damping unit 42 further comprises an actuating means 48, which - as explained below - is provided for actuation of the damping means 44 during a closing movement of the door 18. It is movably mounted for movement parallel to the main extension direction 27 of the door body 26 or to the axis of symmetry 38 of the power unit 36 relative to the door body 26 and to the housing 46. The actuating means 48, which is designed in particular as a plunger, engages in the housing 46, in which it cooperates according to a known principle with the damping medium to a damping effect. To the actuating means 48 further includes a coupling means 50 of the damping unit 42, which is provided for coupling to the movement transmission unit 40 and is formed in the form of a pair of eyelets, each having a slot 52. An embodiment of the coupling means 50 with only one eyelet with a slot 52 is conceivable. These elongated holes 52 extend parallel to the main extension direction 27 of the door body 26 and surround the means 54 of the movement transfer unit 40, which is rigidly connected to the connecting rod 34 on the one hand and on the other hand with the power unit 36. For example, the means 54 may be integrally formed with the power unit 36. The means 54, which is formed as a two opposite side walls of the door body 26 connecting crossbar is movably mounted relative to the door body 26. For this purpose, 26 oblong holes 56 are recessed in opposite side walls of the door body, in each of which one end of the means 54 is guided. By the engagement of the means 54 of the movement transmission unit 40 in the coupling means 50 of the damping unit 42 and the rigid coupling With the power unit 36, the motion transmission unit 40 serves to transmit movement of the door 18 relative to the functional body 26 to both the power unit 36 and the damping unit 42. This is realized particularly simply in the embodiment shown by the integral means 54 both with the power unit 36 for varying the generated force as well as with the damping unit 42 cooperates to achieve a damping effect. The interaction of the movement transfer unit 40, the means 54 and the coupling means 50 to achieve a damping effect in a closing movement of the door 18 will be described in more detail below.

The power unit 36 and the damping unit 42 represent two units which are arranged such that one of the units is at least partially incorporated in the other unit. As a result, a large space can be advantageously saved. In the embodiment shown, the damping unit 42 with the damping means 44, the actuating means 48 and the coupling means 50 is partially incorporated in the power unit 36, namely, it is partially disposed in a space 58 formed by the power unit 36. In particular, the damping means 44 with the housing 46 and the actuating means 48 are disposed completely in this space 58, wherein the damping means 44 and the actuating means 48 are surrounded by the spring coils by 360 °, while the coupling means 50 in engagement with the means 54 below the power unit 36 stands and extends in the direction of the pivot axis 32 out. Thus, with the damping means 44 and the actuating means 48, a majority of the damping unit 42 is received in the space 58. The housing 46 of the damping means 44 is cylindrical and has a cylinder axis. The actuating means 48 is likewise cylindrical, with a cylinder axis which corresponds to the cylinder axis of the damping means 44. The diameter of the actuating means 48 is smaller than the diameter of the damping means 44. The cylinder axes form an axis of symmetry of the damping unit 42. This axis of symmetry corresponds to the axis of symmetry 38 of the power unit 36, so that the power unit 36 and the damping unit 42 are arranged coaxially to one another. The inventive arrangement of the power unit 36 and the damping unit 42 can be dispensed with an additional space for the damping unit 42, wherein existing door body 26 can be achieved with standardized dimensions. Furthermore, a damping unit 42 with the proposal according to the invention can thereby be inserted particularly easily into further door bodies be adapted to other doors of different sizes and weights.

The closing device 22 also has a holding means 60, which serves to hold the power unit 36. By the holding means 60, the power unit 36 which is mounted in the door body 26, rigidly connected at its upper end with this door body 26. The holding means 60 has at its upper end a hook 62 which is supported on a transverse bar 64 extending between two opposite side walls of the door body 26 and rigidly coupled to these side walls. Integrally connected to the hook 62 is a partial region 66 which, starting from the hook 62, extends downwards and has an interface which is not visible in the figure and which is provided for fastening the force unit 36. In particular, the interface for producing a positive connection with the force unit 36 is provided. In the present example, the power unit 36 is attached to the holding means 60 by making a screw connection. Other types of fasteners which appear to be suitable for the person skilled in the art, for example the production of a latching connection or an adhesive connection, such as a welded connection, are likewise conceivable. Below the interface, the holding means 60 continues as a guide region 68, which engages in the space 58 and serves to guide the power unit 36 during an expansion and relaxation process. Between the uppermost windings of the power unit 36 punched parts 70 are arranged from sheet metal. In the present example, a connecting piece 72 further adjoins the guide region 68, by means of which the damping means 44 is connected to the holding means 60, namely to the guide region 68. Through the connector 72, which is arranged completely in the space 58, the damping means 44 is rigidly coupled to the door body 26. In an alternative embodiment, it is conceivable that the damping means 44 is mounted floating in the space 58, wherein it - guided by the power unit 36 - can perform movements in the main extension direction 27 of the door body 26 relative to this. In this case, a movement of the damping means 44 triggered by the actuating means 48 can be stopped upwards by striking it on the underside of the guide region 68, this guide region 68 then being additionally designed as a locking means for the damping means 44. In both embodiments, the holding means 60 serves either directly or via the connecting piece 72 indirectly as support means for supporting the damping means 44 in a damping operation, when a damping operation by the action of the movement transmission unit 40 with the means 54 is introduced via the coupling means 50 and thereby the actuating means 48 is pressed into the housing 46.

The interaction of the above-described elements of the hinge unit 24.1 during an opening and closing movement of the door 18 will now be explained. When the door 18 moves from the closed position, as described above, the movement of the door 18 is transmitted to the force unit 36 by means of the movement transfer unit 40. Here, the means 54 is moved by the connecting rod member 34 down, whereby the power unit 36 is tensioned. The means 54 is guided in the elongated holes 56 of the door body 26 and the elongated holes 52 of the coupling means 50. The means 54 comes here to abut the lower edge of the slots 52. If the opening movement continues, the coupling means 50 and with it the actuating means 48 is moved downward, wherein the actuating means 48 is driven out of the housing 46 down. The end position of the means 54 at the lower edge of the elongated holes 56 corresponds to the end opening position of the door 18 (Figure 2).

It is now assumed that an operator closes the door 18. Here, the means 54, starting from its end position, guided at the lower edge of the slots 56 and 52 upwards. Since the elongated holes 52 have a smaller length than the elongated holes 56, the means 54 abuts against the upper edge of the slots 52 before the means 54 reaches the upper edge of the elongated holes 56. The dimension of the elongated holes 52 and the relative arrangement of the slots 52 and 56 to each other are selected such that the striking of the means 54 to the upper edge of the slots 52 takes place when the means 54 approximately two-thirds of the length of the slots 56 covered upwards Has. This position of the means 54 corresponds to an intermediate opening position of the door 18 at an opening angle W, which corresponds to approximately 30 °. As the door 18 moves beyond this intermediate opening position toward the closing position, which movement is driven by the force generated by the power unit 36, the coupling means 50, which is now in operative connection with the means 54, is carried upwardly by the means 54 , whereby the actuating means 48 is inserted into the damping means 44. Thus, in the intermediate opening position of the door 18 at which the coupling means 50 and the means 54 engage each other, the damping unit 42 is turned on and the movement of the door 18 beyond the intermediate opening position to the closing position is damped by the action of the damping unit 42. This part of the closing movement of the door 18, namely the part, starting from the intermediate opening position to the closing position, which represents approximately one third of the total closing movement from the Endöffnungsposition, damped by the damping unit 42. The intermediate opening position, in which the damping unit 42 is turned on from the end opening position during a closing movement, is predetermined by the damping unit 42 with the design of the coupling means 50 and its arrangement relative to the door body 26.
