Description

The invention relates to a household refrigerator with a housing in which at least one limited by walls of an inner container first receiving space for food is formed. The domestic refrigerator further comprises a linear in the depth direction of this household refrigeration appliance and relative to the housing in a direction of movement movable drawer. This pull-out trolley comprises a door for closing the first receiving space.

From the DE 10 2013 211 103 A1 a refrigeration device is known in which a laterally hinged door is opened with a door opening aid.

From the WO 2009/127696 A2 is a refrigerator with a drawer known. It is envisaged that in this case a drawer-in-drawer system is formed.

In addition, from the DE 10 2008 040 609 A1 a refrigerator with a so-called Apothekerauszug known. It is envisaged there that a carriage is provided in an interior retractable and retractable, which has a door, on which a plurality of arranged at different altitudes shelves are formed.

The extraction of such a drawer car from the fully closed position can be difficult to navigate just in the case of fully equipped pull-out trolley.

It is an object of the present invention to provide a household refrigerator, in which the mobility of the drawer car is improved.

This object is achieved by a household refrigerator according to claim 1.

An inventive domestic refrigerator comprises a housing in which at least one limited by walls of an inner container first receiving space for food is formed. The domestic refrigerator further comprises a drawer, which is in the depth direction of the household refrigerator linear and relative to the housing in a direction of movement into the first receiving space and out of the first receiving space displaced. In addition, the drawer comprises a door for closing the first receiving space when the drawer is in the fully inserted end position.

An essential idea of the invention is the fact that the household refrigerator has an electronic drawer opening aid. With this, the pullout trolley can be opened starting from its closed position to a pull-out carriage opening path or pushed outward. This is then done automatically by this electronic drawer opening aid, if such an extension of the drawer carriage is desired on the user side and in particular accessed and started by a user-side action.

The household refrigerator also includes a separate electronic drawer opening aid mechanical Öffnungswegverlängerer coupled with the drawer opening aid. Through the Öffnungswegverlängerer the pull-out carriage opening path when opening or pushing out the drawer carriage on an extended drawer carriage opening path is extended. This thus means that the Öffnungswegverlängerer is so coupled with the electronic drawer opening aid that when initiated by the electronic drawer opening aid or carried out moving the drawer carriage from the closed end position to an open position then not only the drawer opening path of the drawer is run through, but automatically and independently a longer path in this regard is passed, namely the extended Auszugswagen-Öffnungsweg. This embodiment thus makes it possible, especially for pull-out cars, to move them with a larger extension path while at the same time reducing the load on the electronic drawer opening aid. Since a drawer car can be loaded with food and / or storage vessels due to its design also circumferentially, relatively high masses or weights can occur here, which then have to be moved out of a rest position. Since in the context of the closed state of such a drawer carriage and thus in the inserted end position, in particular due to possibly generated negative pressure in the first receiving space, the opening and ejection is difficult, this is also favored by the invention now. By this extended or extended drawer carriage opening path then the further handling for a user for complete removal is made easier in the fully open end position. Another significant advantage is the fact that different extended Auszugswagen-opening paths can then be realized by different Öffnungswegverlängerer and yet a same electronic drawer opening aid can be provided for these variants. This pull-out carriage opening aid can then be used as an equal component for different household refrigerators. Demand-dependent is then for variants the household refrigerator only the Öffnungswegverlängerer designed individually, so that can be here pretend shorter or longer extended Auszugswagen-opening paths.

Preferably, the mechanical Öffnungswegverlängerer is formed such that the extended Auszugswagen-opening path is at least 50%, in particular at least 90%, greater or longer than the Auszugswagen-opening path, which can be achieved only by the electronic drawer opening help alone. By such a long range extensions or extensions of the drawer opening path, it is possible that the electronic drawer opening aid can be relatively small dimensions.

Preferably, the pull-out carriage opening path and the extended pull-out carriage opening path are straight-line paths. This means that the electronic drawer opening aid and the mechanical Öffnungswegverlängerer are designed so that their direction of movement or their force to the opening of the drawer carriage is rectilinear. Especially with drawer, which can be moved back and forth only in a straight linear motion, this is advantageous because there are no undesirable forces to the direction of movement at an angle and thus no jamming or Verspreizungen occur in this linear movement of the drawer car. In particular, it is provided that the force effects of the electronic drawer opening aid and the mechanical Öffnungswegverlängerers are oriented parallel to the linear movement possibility of the drawer car.

It is preferably provided that the extended pull-out carriage opening path is between 4 cm and 7 cm, in particular between 4 cm and 6 cm.

In particular, the mechanical Öffnungswegverlängerer on a scissors gear. This is a very advantageous embodiment, since the scissors gear very gleichgleich generates a linear force on the drawer and on the other hand is mechanically very stable. As a result, a relatively heavy pull-out carriage can be moved uniformly even without twisting the scissors gear. In addition, it is also possible with such a scissors gear improved to produce mechanical contacts with the drawer cars, so that force discharges on the drawer and the entire movement of the drawer carriage are favored.

It is preferably provided that the mechanical Öffnungswegverlängerer is coupled with a retraction of the drawer carriage in the closed end position with the drawer opening aid. This is advantageous to the effect that then also the Öffnungswegverlängerer is automatically transferred back to its retracted position and in a next extension of the drawer then already fundamentally present again in this extendable position.

The drawer opening aid can preferably be activated by a user by actuating an operating element. This can be done for example by touching a front portion of a door of the drawer or by touching or gripping a door handle of the drawer car. In this context, for example, a touch-sensitive control element may be provided or else a control element to be pressed mechanically, which then moves relative to the surrounding area by pressing, as is the case, for example, with a push button or a toggle switch or a rotary element.

The drawer opening aid preferably has a plunger which can be extended to the drawer opening path by an engine and a gear of the drawer opening aid coupled thereto. Especially with such an embodiment of the electronic drawer opening aid can be formed by the addition of a mechanical Öffnungswegverlängerer the plunger is relatively small and with a small stroke. As a result, it is no longer necessary to provide a relatively large-sized engine.

This plunger is in particular straight and thus moved linear. By the plunger and the mechanical Öffnungswegverlängerer the excerpt car is pressed from its fully inserted and thus its closed end position.

Since it is necessary especially for pull-out trolley due to the structural design and the movement path, in contrast to laterally hinged doors, which are then pivoted about a horizontal axis, the independent opening travel larger than in such pivotable doors, the invention is particularly advantageous.

In particular, it is provided that the plunger of the electronic drawer opening aid with a crossing point on which lever elements of the scissors gear are rotatably connected to each other, is connected. This will be a very achieved symmetrical arrangement of the plunger to the components of the scissors gear. The occurring by the plunger displacement is then transmitted relatively evenly to the mechanical Öffnungswegverlängerer, so just in a scissors gear then a very uniform force can be transmitted to the Öffnungswegverlängerer and the lever elements of the scissors gear can move very smoothly.

The directions "width direction", "height direction", "depth direction", "top", "bottom", "front", "rear", "outside", "inside" etc. refer to the state of one to one conventional household refrigerating appliance set up, the door is arranged in front for a viewer and the back behind.

The household refrigerator 1 includes a housing 2 in which an inner container is arranged, which has a first receiving space 3 which is a freezer room, for example, and a second storage room 4 which is, for example, a refrigerator. The two recording rooms 3 and 4 are separated from each other and each with separate doors 5 and 6 closable. In 1 is the second recording room 4 im through the door 6 shown closed state.

In contrast, the door is 5 open. The door 5 is here in the embodiment part of a drawer car 7 , with a linear movement in the depth direction and thus in the z direction of the household refrigerator 1 pulled out in the straight direction of movement and can be inserted again. In 1 is the excerpt car 7 shown in fully extended condition.

The pull-out cart 7 also includes, for example, a first food intake unit 8th which is a tub-like container. This food intake unit 8th is thus not accessible from the side and can be reached only in the vertical direction and thus in the y-direction from above and thus is an access into the interior or the useful volume of this food storage container or this food receiving unit 8th only possible from above. In the exemplary embodiment, this is a first food intake unit 8th arranged in the height direction and thus in the y-direction at a first altitude, preferably on a plate-like base 9 the door 6 attached.

The pull-out cart 7 also includes, by way of example, two second food intake units 10 and 11 , which are also designed as a trough-like container and only from above their useful volume accessible. As can be seen, these are in number of exemplary second food intake units 10 and 11 on a first altitude, on which the first food intake unit 8th is arranged, different, higher located second altitude.

As in 1 is shown on an outer side of the plate-like base part 9 a handle 12 educated.

The household refrigerator 1 includes an electronic drawer opening aid 13 , with which the drawer car 7 starting from its closed position to a rectilinear, in the depth direction and thus oriented in the z-direction pull-out carriage opening path can be opened or ejected. In 1 is only the reference number of this electronic drawer opening aid 13 shown and the clarity serving the actual representational components are not shown. In addition, the household refrigerator includes 1 a separate mechanical opening path extender 14 Using the electronic abstract carriage opening aid 13 is coupled. Through the opening travel extender 14 is the pull-out carriage opening path, the only by the electronic drawer opening aid 13 can be provided when opening the drawer car 7 Extendable on an extended extension carriage opening path in this respect.

In 2 is an exemplary embodiment of the device comprising the electronic drawer opening aid 13 and the coupled mechanical Öffnungswegverlängerers 14 shown. In this embodiment and illustration are both the electronic drawer opening aid 13 as well as the mechanical opening stroke extender 14 shown fully retracted.

In the embodiment, the mechanical Öffnungswegverlängerer 14 a scissors gear, which has several lever arms 14a . 14b . 14c . 14d has, which are hinged together. Preferably in this context is the electronic drawer opening aid 13 without direct contact with the pull-out car 7 , in particular without direct contact with the plate-shaped base part 9 the door 5 , In this context, a direct mechanical contact between the mechanical Öffnungswegverlängerer 14 and the pull-out cart 7 , in particular the basic part 9 , intended.

In addition, the mechanical coupling between the electronic drawer opening aid 13 and the mechanical opening stroke extender 14 at a coupling point 15 intended. The coupling point 15 is at the same time also a hinge connection between the lever elements 14a and 14b ,

The electronic drawer carriage opening aid 13 includes a motor 13a and a so coupled via a transmission and by the engine 13a movable plunger 13b , The pestle 13b is a pull-out carriage opening path straight and linear, in particular in the z-direction, displaceable, said pull-out carriage opening path between 2 cm and 3 cm, in particular about 2.5 cm.

By coupling the electronic drawer opening aid 13 with the additional mechanical opening stroke extender 14 an extended Auszugswagen-opening path is reached, which is between 4.5 cm and 6 cm, in particular about 5 cm.

In 3 For this purpose, a situation is shown in which the extended extension carriage opening path is reached to the maximum and thus both the electronic pull-out carriage opening aid 13 as well as the mechanical opening stroke extender 14 are maximally extended. The coupling between the electronic drawer opening aid 13 and the mechanical opening stroke extender 14 In addition, it is such that by the movement of the plunger 13b automatically and at the same time the movement and thus opening or spreading of the scissors gear of the mechanical Öffnungswegverlängerers 14 is done and then on the way of the plunger 13b also concurrently then this scissors gear is opened or spread. In particular, then the coupling is also such that when the plunger 13b has reached its maximum displacement and thus the Auszugswagen-opening path, and the Öffnungswegverlängerer 14 has reached the extended extension carriage opening path.
