Description

Technical Field

[0001] The present invention relates to household appliances, in particular refrigerators or freezers, comprising a framework and a slide element that can be pulled out from the framework, and a storage container that can be raised can be taken out from the framework by the slide element.

Background Art

[0002] In household appliances such as refrigerators and freezers, in addition to compartments for storing items such as foodstuffs, there are often containers that are stored in guide rails and can be moved outside the framework to tidy up or take out the stored goods. When the container is arranged in the lower region of the household appliance extending to the base, this is cumbersome for the user.

[0003] European Patent No. 1630506 describes a refrigerator in which a basket is displaceably arranged in a drawer, and a lifting device is assigned to the basket. After the drawer is pulled out, it is driven by a drive unit and lifted, making it easier to store and take out goods. The lifting device comprises a frame mounted to move linearly on vertically aligned guide rails, and a basket is arranged as a storage container on the frame. To raise and lower the lifting frame, an electrically driven pivoting arm is provided, and a roller that rolls on the lower side of the lifting frame is rotatably mounted at its free end. The drive unit comprising the guide for the lifting frame and the pivoting arm is mounted inside the front panel, and the front panel is mounted to the aforementioned drawer guide and can be moved from the framework.

[0004] The drawback of such a device is that the drawer is pulled out manually, for which the user has to bend down to the drawer. Therefore, it would be desirable if the drawer could also be pulled out automatically. However, in this case, either two separate drive units for the pulling-out movement and the lifting movement respectively, or a drive unit that is temporarily coupled in a complex way to the pulling-out movement and temporarily coupled in a complex way to the lifting-out movement would be required.

SUMMARY OF THE INVENTION

PROBLEM TO BE SOLVED BY THE INVENTION

[0005] The object of the present invention is to create a household appliance of the aforementioned type that can move and lift a storage container out of a frame without the need for manual intervention. A further object is to enable this to be achieved by a single drive unit that is mechanically simple and drives both the pressing and lifting operations in a coordinated manner without performing a series of complex and error-prone controls.

MEANS FOR SOLVING THE PROBLEM

[0006] This object is solved by a household appliance having the features of the independent claims. Advantageous configurations and further developments are the subject matter of the dependent claims.

[0007] The household appliance according to the present invention is provided with a pressing chain assembly having at least one pressing chain driven by a drive assembly, wherein at least one pressing chain is fixed to the storage container by a free end and is pulled between the drive assembly and the storage container through a return guide arranged on a slide element.

[0008] The pressing chain is a chain in which the movement between two chain links is only possible in one turning direction of the links relative to each other, whereby not only is the chain loaded in a tensioned state, but also the pressing force can be propagated. According to the present invention, this characteristic is utilized in a pressing chain which is one element to realize the sliding movement of the sliding element with respect to the support container and the upward movement of the support container after deflection.

[0009] Therefore, at least one pressing chain driven by the drive assembly acts directly only on the storage container, but due to the deflection, the sliding element and the storage container are subjected to a force in the pulling-out direction.

[0010] The fact that the sliding movement requires a considerably lower force than the upward movement means that a series of controls are inherent. Starting from the state where the sliding element is retracted, first the sliding element is pulled out to the stopper, and further the pressing chain is pushed to lift the storage container. When the pressing chain is pulled in again, this series of operations runs in reverse without requiring a complicated series of controls. For this purpose, it is preferable that the return guide is configured to convert the horizontal movement of the pressing chain into a vertical movement. For example, it may have a circular quarter slide path for the pressing chain.

[0011] More advantageously, at least one pressing chain also represents the lifting guide of the storage container at the same time, which also simplifies the structure of the configuration.

[0012] In the context of the application, the term "storage container" means any configuration that enables the storage of an object that can be accommodated. In particular, the storage container may be a configuration consisting of a plurality of parts, for example, it comprises a frame-shaped container that accommodates at least one removable container.

[0013] In an advantageous configuration of the household appliance, at least one pressing chain is fixed to the rear (lateral) side of the storage container, particularly in the center of this side, as seen in the pulling-out direction. In this way, a single pressing chain is sufficient for lifting, particularly in the case of a storage container that is not overly wide. In a further exemplary embodiment for supporting the lifting guide, the storage container can be additionally attached to the sliding element such that it is vertically movable via the sliding guide.

[0014] In a further advantageous configuration of the household appliance, the pressing chain assembly includes a plurality of pressing chains that extend parallel to and are spaced apart from each other. One pressing chain is fixed to the center of the rear (lateral) side of the storage container as described above, and another is fixed to each of the two corner regions or sides of the storage container. In one configuration, it is further provided that at least two of the plurality of pressing chains are spaced apart parallel to each other in the pulling-out direction of the sliding element, thereby achieving stable support of the storage container against backward tipping (i.e., with respect to the extension direction) during lifting.

[0015] The plurality of pressing chains are preferably moved synchronously by a drive assembly. This can be done mechanically, for example, via a synchronizing shaft that extends transversely to the arrangement of the pressing chains, or by a stepper motor, or by a DC motor equipped with a hall sensor.

[0016] The restricted freedom of movement of the chain links of the pressing chain prevents them from bending, and thus prevents the storage container from tilting forward, i.e., moving away from the framework. The fact that the pressing chains are arranged in the front and rear regions of the storage container and are pulled out in parallel at the same time also prevents the storage container from tilting backward, i.e., moving towards the framework.

[0017] In particular, when at least one pressing chain is non-rotatably connected to the storage container at its end, a high stability of the lifting guide is achieved by the pressing chain assembly. For this purpose, at least one chain sleeve can be attached to the storage container or can be formed in the storage container, for example, the free end of at least one pressing chain is non-rotatably fixed.

[0018] In another advantageous configuration of the household appliance, the drive assembly comprises a drive motor having an output gear that engages with at least one pressing chain. The drive motor preferably acts on the output gear via a self-locking gear, such as a worm gear. Thereafter, the storage container remains in the lifted position without taking further action. Alternatively, a blocking device or a braking device may be provided to prevent the support container from sinking. Also, in order to achieve the holding function, it is also conceivable to continue to energize the drive motor at a lower operating current at the raised position of the storage container.

[0019] The slide element can be linearly guided on the framework by at least one drawer guide. Preferably, the drawer guide comprises rolling elements associated with a smoothly running guide. The smoothly running guide is advantageous for a series of operations. This prevents the storage container from being lifted until the sliding movement is already completed or until the storage container is lowered.

[0020] Furthermore, a retraction lock, for example, a retraction lock by latch means or claws, can be provided to prevent the drawer guide from being retracted as long as the storage container is still lifted. This retraction lock can act non-actively and / or actively and can be actuated or released, for example, by the storage container. Alternatively, it is possible to consider the use of an electromechanical switch or any type of sensor that detects whether the storage container is in the lowered position or the raised position.

[0021] Particularly advantageously, the above-described device with a liftable storage container can be implemented in a refrigerator and / or freezer as a household appliance.

Best Mode for Carrying Out the Invention

[0023] In all the figures, the same reference numerals indicate elements that act in the same or similar manner. For the sake of clarity, not all elements in all the drawings are labeled.

[0024] In the description, terms such as "upper", "lower", "left", and "right" initially mean the exemplary expressions selected in each drawing. For the terms "upper" and "lower", the display in the figure usually coincides with the directions adopted in space. The terms "front" and "rear" should be understood with respect to the household appliance. In front of the household appliance, there is a front side facing the user, and on it, there are doors, flaps, or similar elements of the household appliance.

[0025] Figures 1a - 1d show a first exemplary embodiment of the household appliance 1 in perspective views for different states of the movement of the storage container 41 in each case. In Figures 2a - 2d, the household appliance 1 is shown in different vertical cross-sections for the same movement state of the storage container 41 in each case.

[0026] Before the detailed technical implementation is described below, first, an overview of the operation procedure is shown. The partial images with the same subscripts (a, b, c, d) in two consecutive figures of Figures 1a - 1d and Figures 2a - 2d show the same state in the operation procedure respectively.

[0027] Household appliance 1 has a framework 2 with side walls 21 and two or more bases 22. For clarity, the rear wall is not shown. Household appliance 1 may be, for example, a refrigerator or a freezer. Thus, household appliance 1 generally has a thermally insulated framework of a number of shells, and technical cooling and sealing devices for closing the openings. For clarity, these are not reproduced in the drawings of the present application. The representation of the framework 2 should be considered, in that sense, as a purely schematic representation. The framework 2 has an opening facing forward, one of which is here closed by the front panel 31 (Figs. 1a, 2a).

[0028] The front panel 31 is part of a slide element 3, which also comprises a drawer guide 32 on which the front panel 31 is guided and through which the front panel 31 is pulled out of the framework 2. The connection between the front panel 31 and the drawer guide is realized by a lateral frame element 33. The slide element 3 is configured, for example, similarly to a drawer, but, unlike a drawer, does not require a base.

[0029] When the release device is actuated, the operating procedure begins with the pulling out of the slide element 3, as can be seen in Figs. 1b and 2b. The entire operating procedure, i.e., the pulling out of the slide element 3, is also driven by a drive assembly 5, which can be seen, for example, in the cross-sectional views of Figs. 2a - 2d. The drive assembly 5 comprises, for example, a drive motor with a downstream gearbox and will be explained in more detail in connection with Fig. 4.

[0030] The drive assembly 5 is controlled by a control device, which is not visible here and is actuated by a release device. This release device can be, for example, a manually actuated push button arranged at a convenient reach height on the household appliance 1. Alternatively or additionally, a remote trigger is executed, for example, via a wireless switch coupled to the control device, which wireless switch may be, for example, a mobile terminal such as the user's mobile phone. Contact-sensing or proximity-sensing switches, and / or switches controlled by voice or gesture may also be used.

[0031] Due to the slide element 3, the storage container 41 first moves substantially forward from the frame 2 until it reaches the fully extended position (Figs. 1c, 2c) (Figs. 1b, 2b). In a further operating procedure (see Figs. 1d, 2d), the storage container 41 is lifted upwards while maintaining its orientation.

[0032] It is understood that the opening procedure shown in Figs. 1a - 1d or Figs. 2a - 2d can be executed in reverse to lower the storage container 41 again and move it into the frame 2. This is preferably carried out after a re - request by the user. Alternatively or furthermore, after a certain time has elapsed since the storage container 41 has been pulled out to the position shown in Fig. 1d, perhaps after an acoustic signal as a display, it can be considered that this is automatically pulled in again. In this way, inadvertent failure to close the domestic appliance 1 can be prevented.

[0033] Sensors can be used to detect the presence of a person in the area of the domestic appliance 1, so that the retraction only takes place when there is no person in the vicinity of the domestic appliance 1, and the storage container 41 left intentionally in the pulled - out position cannot be undesirably retracted, and / or the risk of injury in the case of an unexpected retraction can be eliminated.

[0034] The details of the technical implementation of the above - mentioned operating procedure will be described below. As already mentioned, the overall movement is driven by a drive assembly 5 arranged in the rear region of the frame 2. Alternatively, the drive assembly 5 can also be arranged outside the frame 2.

[0035] The storage container 41 and the slide element 3 are indirectly connected to the drive assembly 5 via a pressing chain assembly 42, in this case comprising three pressing chains 421. A pressing chain is a chain where the movement between two chain links is only possible in one swiveling direction of the links relative to each other. This is achieved by the corresponding geometric shape of the chain links, where the end regions of the chain links are rounded only towards one side of the chain. The chain links can pivot relative to each other in this direction, but when bent in the opposite direction, they are held stationary relative to each other due to the corresponding shape. The possible shape of the pressing chain 421 can be seen enlarged in, for example, FIG. 4.

[0036] The three pressing chains 421 are pushed forward or pulled backward in synchronization by the drive assembly 5. Inside the slide element 3, the pressing chains 421 each travel along a return guide 422, in which they are deflected upward along a quarter-circular slide path. Thus, the pressing chains 421 are arranged so as to be deflectable upward. Next, in the example shown by the chain sleeve 411, the pressing chain 421 is coupled to the storage container 41, and the pressing chain 421 is inserted into the chain sleeve 411 by at least one, preferably several, chain links. The chain sleeve 411 may be arranged directly on the storage container 41 or, for example, indirectly on a frame into which the storage container 41 is inserted.

[0037] Of the three pressing chains 421, two pressing chains extend laterally along the upper corners of the two front faces of the storage container 41. The third pressing chain 421 ends approximately at the center of the upper rear transverse edge of the storage container 41. Thus, the chain sleeve 411 is attached to the upper corners of the two front faces and the approximately central rear transverse edge of the storage container 41.

[0038] Such an arrangement of the three pressing chains 421 supports the storage container 41 in a well-balanced and stable manner when lifted, preventing tipping over.

[0039] Rather than being arranged in the center, arranging "at the corner" means that one or more pressing chains 421 are intentionally attached with a shift from the center. Further, the pressing chain 421 is attached toward the corner of the storage container, and the lever arm for stabilizing the storage container 41 becomes larger.

[0040] As shown in FIG. 1a or FIG. 2a, starting from the retracted position of the slide element 3, the drive assembly 5 is actuated to pull out the pressing chain 421, which is first connected to the pulling out of the slide element 3 as shown in FIGS. 1b or 2b respectively. The prerequisite for this is that a smaller force is required for the movement of pushing in the slide element 3 than for the deflection of the pressing chain 421 or the lifting of the storage container 41. In particular, in the case of the drawing guide 32 that is not configured as a slide guide and is provided with rolling elements, this prerequisite is also given when the storage container 41 is not filled.

[0041] The pulling out of the slide element 3 continues with further actuation of the drive assembly 5 until the slide element 3 reaches its maximum pulling out position and stops at this position, for example, by a stopper formed in the drawing guide 32. The maximum pulling out positions of the slide element 3 are shown in FIGS. 1c and 2c respectively.

[0042] The further pulling out of the pressing chain 421 brings about the deflection of its horizontal movement in the return guide 422 and the vertical movement of the front surface region of the pressing chain 421, and accordingly, the storage container 41 is lifted via the chain sleeve 411 as shown in FIGS. 1d and 2d respectively. Thereby, the maximum height reached together with the storage container 41 is predetermined by the length of the pressing chain 421 used. The movement is stopped by sensing the maximum pulling out position and controlling the drive assembly 5 accordingly. For example, limitation by a mechanical stopper realized at the free end of the pressing chain 421 is also conceivable. Any type of limit switch can be used.

[0043] By using the self-locking drive assembly 5 and / or by continuously energizing the drive assembly 5, it is possible to hold the storage container 41 in the raised position at an optionally reduced current value until the storage container 41 descends and is retracted again.

[0044] In the illustrated exemplary embodiment, the vertical guidance, i.e., the guidance of the storage container 41 during the lifting movement, is achieved only by the pressing chain 421. Since the degree of freedom of movement of the chain links of the pressing chain 421 is restricted, buckling of the pressing chain 421 and thus tilting forward of the storage container 41, i.e., moving away from the frame 2, is prevented.

[0045] Since the pressing chain 421 is arranged in the front and rear regions of the storage container 41 and also extends in a synchronized and parallel manner, tilting of the storage container 41 towards the rear, i.e., towards the frame 2, is also prevented. The stability of this arrangement is enhanced by fixing at least one, more preferably a plurality, of the chain links of the pressing chain 421 rotatably to the storage container 41 and fixing them to the chain sleeve 411.

[0046] The return guide 422 of the laterally arranged pressing chain 421 is directly attached to the frame element 33. The return guide 422 for the middle part of the pressing chain 421 is located on the intersection member 423 behind the center of the storage container 41. In the illustrated exemplary embodiment, the intersection member 423 is formed by a tube to save material.

[0047] Figures 3a, 3b and 4 - 6 show the details of the pressing chain assembly 42 and the drive assembly 5 in various views.

[0048] Figures 3a and 3b first show a vertical cross-section through the pressing chain assembly 42 and the drive assembly 5 in the plane in which the central pressing chain 421 extends. Here, Figure 3a shows the fully extended position with the storage container 41 still in a lowered position, and Figure 3b shows the fully extended state with the storage container 41 raised. Thus, the state shown in Figure 3a corresponds to the states shown in Figures 1c and 2c respectively, and the state shown in Figure 3b corresponds to the states shown in Figures 1d and 2d respectively.

[0049] Figure 4 shows an enlarged perspective view of the drive assembly 5. Figure 5 is also a perspective view showing the area of the central pressing chain 421 in the pulled-out state, and Figure 6 shows a detailed perspective view of the area of the central return guide 422 with the storage container 41 slightly raised.

[0050] The drive assembly 5 has a drive motor 51 that acts on the pressing chain 421 via an output gear 52. Advantageously, only one drive assembly 5 with only one drive motor 51 is provided for the overall configuration. In the illustrated exemplary embodiment, the drive motor 51 acts on the middle part of the pressing chain 421 via the output gear 52.

[0051] The drive motor 51 is preferably provided with an integrated gearbox that moves the pressing chain 421 with a correspondingly reduced speed and high thrust. Advantageously, the gearbox is self-locked, for example, by including a single or multiple worm gears. Power is transmitted from the output gear 52 to the pressing chain 421 by guiding the pressing chain 421 around the output gear 52 within a certain angular range, in this example approximately 60 degrees.

[0052] The end of the pressing chain 421 facing away from the storage container 41 is guided within the receiving tube 53, which is substantially vertical and can be guided along the back side of the furniture frame 2. The receiving tube 53 is formed as a tubular socket as in the illustrated example, so that the pressing chain 421 can move freely upward behind the furniture frame when the slide element 3 is retracted.

[0053] Alternatively, the receiving tube 53 may have a corresponding length to completely accommodate the pressing chain 421 and may be closed. A closed receiving tube 53 is advantageous to avoid contamination of the pressing chain 421. Alternatively, another form of chain storage device can be used following a shortened receiving tube 53 around which the chain is wound, for example, when the installation space of the furniture frame is restricted in this area and a larger vertical drawer is not possible. For the sake of explanation, the free end of the pressing chain 421 is shown shortened in Figure 3a.

[0054] To enable the movement of the device with only one drive motor 51 and to achieve synchronization of the movement of all three pressing chains 421, the movement of the central pressing chain 421 is transmitted to the lateral pressing chains 421 via a synchronization shaft 56. For this purpose, a synchronization gear 54 is provided that picks up the movement of the central pressing chain 421 with a gear 55 and transmits this to the equivalent synchronization shafts 56 on both sides. The equivalent synchronization gears drive the respective lateral pressing chains 421 in turn. In an alternative configuration, synchronization can also be performed directly from the output gear 52 of the drive motor 51 via a synchronization shaft.

[0055] It is understood that such mechanical synchronization may also be implemented when multiple drive motors are provided. Also, in the illustrated example, the position of the drive motor driving the middle part of the pressing chain 421 is purely exemplary. It is equally conceivable that only one or both of the lateral pressing chains 421 are driven and their movement is transmitted via the corresponding synchronization shafts 56.

[0056] Figures 7 and 8 each show a detailed perspective view of a second exemplary embodiment of a household appliance with a slide element 3 and a slide and lift device 4. Regarding the basic structure, the examples of the embodiments shown here correspond to the examples of the embodiments described above, and the description thereof is explicitly referred to here. In particular, the differences between the two exemplary embodiments are described below.

[0057] Also in this exemplary embodiment, a storage container 41 is arranged on the slide element 3, and a frame element 33 guided via a drawer guide 32 and a front panel 31 connecting the frame element 33 are shown in FIGS. 7 and 8. In this (above-described) exemplary embodiment, the drawer guide 32 is configured as a drawer guide that is fully pulled out, and includes a frame rail 321 attached to the framework 2, a central rail 322 mounted so as to be displaceable with respect to the frame rail 321, and a running rail 323 attached so as to be displaceable with respect to the central rail 322.

[0058] In the exemplary embodiments of FIGS. 7 and 8, a lock lever 324 is pivotally mounted on the track. This lock lever 324 is formed as a two-sided lever and includes a first lever arm on the front side of the lock lever 324 that freely projects forward toward the front panel 31. A claw 325 is provided on the second lever arm on the opposite side. As shown in the figure, in the position where the drawer guide 32 is fully pulled out, it projects along the central rail 322 in front of the front end of the frame rail 321. The lock lever 324 is slightly angled. In the illustrated position, it is assumed that when the front part of the lock lever 324 moves freely, the reinsertion of the drawer guide 32 is prevented due to gravity because the claw 325 hits the front end of the frame rail 321 and stops.

[0059] The locking lever 324 is assumed to be in the illustrated position as long as the storage container 41 is rising. When the storage container 41 descends, an actuator 412 that protrudes laterally from the storage container 41 and has a shape like a bolt here pushes down the free end of the locking lever 324, the claw 325 rises, and the movement of the running rail or the central rail relative to the framework rail 321 is released again.

[0060] The locking lever 324, together with the actuator 412, forms a retraction lock that ensures that the slide element 3 is not retracted when the storage container 41 rises. Without the retraction lock, the storage container 41 could collide with the framework 2 of the household appliance 1. As an alternative possible retraction lock, the use of an electromechanical switch or sensor that detects whether the storage container 41 is in the lowered position or the raised position is conceivable. Then, an appropriate actuator can be used to prevent the retraction of the storage container 41 according to the detected position.

[0061] A further difference between the above exemplary embodiment and the exemplary embodiment of FIGS. 7 and 8 is that, in addition to the pressing chain assembly 42, a slide guide 43 is provided between the slide element 3 and the storage container 41 to support the vertical guidance of the storage container 41. In this example, the slide guide 43 is mounted on the frame element 33 on the side of the slide element 3. Attachment of the slide guide 43 to the front panel 31 is also conceivable.

[0062] With this slide guide 43, the storage container 41 can only move linearly relative to the front panel 31, and tilting is prevented. Thereby, the number of pressing chains 421 can be minimized, and ultimately, although the pressing chain only has to be configured for pulling out and lifting, the additional function of stabilizing the storage container 41 against tipping by the pressing chain 421 is unnecessary. In this exemplary embodiment, in this way, for example, it is sufficient when only the central pressing chain 421 is used.
