Description

Refrigerating appliance with a mechanical

Ventilation device airtight lockable storage compartment

The invention relates to a refrigeration appliance, in particular domestic refrigeration appliance, comprising a body with a coolable interior, a door leaf provided for opening and closing the interior, mounted on the body and an airtightly closable storage compartment arranged in the interior.

DE 102 48 510 A1 discloses a refrigeration device with a housing surrounding a hollow-walled housing and with a vacuum pump which is connected via a suction line to a cavity of the housing. The suction line is also connected to the storage compartment.

Object of the present invention is to provide a refrigeration device with a simple, inexpensive airtight sealable storage compartment.

The object of the invention is achieved by a refrigeration device, in particular

Household refrigerating appliance, comprising a body with a coolable interior, a door leaf provided for opening and closing the interior, a door leaf mounted on the body, and an airtightly closable storage compartment arranged inside, having a mechanical ventilation device for venting through a pressure force acting on the storage compartment and / or or ventilate the storage compartment is to operate.

In known evacuable storage compartments on the one hand controls are provided which serve to open and close the storage compartment and on the other hand separate controls are provided which serve in the

closed storage compartment to cause the generation of a vacuum or serve to ventilate the storage compartment to reduce a pressure prevailing in the storage compartment vacuum to ambient pressure, so that the storage compartment can be opened without much effort. So far, it has been necessary that a vacuum or a vacuum is produced by means of elaborate pump devices and, before opening the storage compartment, first the vacuum by operating a separate

Actuating is to be solved. This is awkward for a user and time-consuming. Also, such a device is very expensive to manufacture and in operation.

The invention therefore provides a solution in which the user can easily ventilate the storage compartment by means of the mechanical ventilation device, for example by a single intuitive movement, i. can dissolve an existing negative pressure or a vacuum and can open the storage compartment almost simultaneously. Thus, the stored in the storage compartment refrigerated goods for the user is directly and quickly accessible. By means of an intuitive closing movement, the storage compartment can be vented by means of the mechanical ventilation device when the closing position is reached, i. the generation of a negative pressure can be achieved by means of this movement.

The mechanical ventilation device can be made of a compressible elastic

Wall section are formed, upon actuation of which an overpressure is built up in the storage compartment and the storage compartment is vented via an opening valve lip. An overpressure is built up by the volume of the storage compartment is reduced by pressing the elastic wall portion and thereby initially increases the internal pressure of the airtight storage compartment. Thereafter, a valve lip opens, so that the overpressure is reduced and air escapes from the storage compartment. When the elastic wall section is released again, the elastic wall section returns to its original position, the storage compartment resuming its original volume, but closing tightly, that is to say the storage compartment is in its original position. the valve lip is closed again, so that no air from the outside can penetrate into the expanding volume and thus a negative pressure in the storage compartment is built. In other words, the mechanical ventilation device may be designed as a ventilation device of known food storage boxes.

The storage compartment may be a compartment permanently installed in the refrigeration appliance, which in particular has a forward position, ie. having opening to the door of the refrigerator. The opening can be closed by a closure lid.

The storage compartment may have a closing cover, in particular pivotally mounted on the storage compartment closure lid with a pressure-opening lock, which is formed at one on the closure lid for unlocking and / or locking acting pressure force to actuate the mechanical ventilation device for venting and / or venting the storage compartment. The storage compartment can be provided analogously to a food storage box with a removable ie separate closure lid. However, the closure cover can also be pivotally mounted, in particular by means of a hinge arrangement, such as a film hinge on the storage compartment. The closing cover can also be one piece with a firmly fixed in the interior of the refrigerator in this respect

Storage compartment be connected. At least one side wall of the storage compartment can be formed by a section of an inner wall of the interior of the refrigeration device.

The pressure-opening lock may be a mechanism mechanically locking and / or unlocking the storage compartment or the closure lid by a compressive force.

The storage compartment can be designed as a drawer, in which by a on the

Drawer acting compressive force to actuate the mechanical ventilation device for venting and / or venting the drawer is. In this case, a pressure movement to be carried out in a conventional manner for opening and / or closing the drawer can also be used to actuate the mechanical ventilation device, which can vent the sealed drawer or ventilate it. Removal of a negative pressure causes the drawer to be opened. If a vented drawer is to be opened, then by a slight pressure on the drawer or a drawer front of the drawer, the mechanical

Ventilation be operated so that the drawer vented and by a subsequent pulling movement, for example by means of a hand of the user, the drawer can be raised. If an open drawer is to be closed again, it is not only the drawer that can be pushed back by pressing the drawer or the drawer front, but also the mechanical drawer

Ventilation device can be actuated so that in the drawer, a negative pressure can be generated as soon as the drawer is hermetically sealed. In that regard, both when opening and when closing the drawer, the mechanical ventilation device to be coupled to the movement to open and / or close the drawer.

A refrigeration device is understood in particular to mean a domestic refrigeration appliance, that is to say a refrigeration appliance that is used for housekeeping in households or in the gastronomy sector is used, and in particular serves to store food and / or drinks at certain temperatures, such as a refrigerator, a

Freezer, fridge freezer or wine fridge.

In addition to a mechanical pressure-opening lock, other types of pressure-opening lock can be provided which not only unlock the drawer by pressing the drawer, but also, in particular simultaneously, actuate the mechanical ventilation device, which is designed for venting and / or aerating the drawer , For example, pressing on one of them

Drawer front of the closed drawer not only unlocks the drawer to open and / or moved on, but also solved an existing negative pressure by aerating the drawer. The drawer or the drawer front may for this purpose have a button, which has, for example, an elastic portion which is part of the mechanical ventilation device in order to ventilate the drawer. In the case of a mechanical pressure-release lock, which is also known as "push-to-open"

Fitting is called, unlocking and possibly a spring-activated pushing out of the drawer triggered by a press, for example, on a drawer front of the drawer, which is unlocked by this pressing the pressure-opening lock. A pressure-opening lock can

For example, be realized by a pin which is guided in a backdrop that can be performed with two different gate paths for opening or closing. For example, the gate may have a so-called heart curve in which the pin is guided so that in a locking position of the pressure-opening lock the pin is spring-biased held in a position in which the pressure-opening latch is in a closed position and by pressing the Pressure-opening lock is pressed in the closing direction of the pin in a gate path along which the pin is moved from the closed position to an open position in which the pressure-opening lock is relaxed and thereby moves to an open position. Upon a subsequent pressing of the pressure-opening lock in the closed position, the pin moves along a second gate path in the closed position, in which the pin is spring-biased held in the closed position. This principle is also used, for example

Applied to ballpoint pens. In one embodiment, the drawer can be slidably mounted in the interior by means of a linear guide and to actuate the mechanical ventilation device by moving the drawer from a closed position against an opening direction for venting. In a modified embodiment, the drawer can be slidably mounted in the interior by means of a linear guide and to actuate the mechanical ventilation device by moving the drawer from an open position in a closing direction for venting.

In a further embodiment, the mechanical ventilation device can be actuated by pressing a drawer front of the drawer. These

Embodiment is particularly suitable for mechanical pressure-opening locks, which are also referred to as "push-to-open" fittings.

The drawer front can in particular have an elastic pressure section, by the actuation of which the mechanical ventilation device is to be actuated for venting and / or ventilating the drawer. It can be provided that the

mechanical ventilation device for venting and / or aerating the drawer can be operated by pressing any point of the drawer front. However, it can also be provided that only a certain, in particular optically exposed pressing portion of the drawer front is formed to be able to activate by pressing the mechanical ventilation device for venting and / or venting the drawer. If pressure is pressed on a different point of the drawer front than the press section intended for this, no activation of the mechanical ventilation device takes place. This can help to avoid unintentional actuation of the mechanical ventilation device.

In one development, a drawer airtight closing ceiling wall of a shelf, in particular designed as a glass plate shelf in

Interior of the refrigerator are formed. The drawer can be mounted extendable in particular hanging on the shelf. In this embodiment, the drawer can be removed, for example, together with the shelf from the refrigerator. The mechanical ventilation device can take place on the

Shelf be provided on a side wall or the bottom of the drawer. If the shelf is designed as a glass plate, a user can change the content of the

See drawer through the transparent shelf without having to open the drawer. This has the particular advantage that the contents of the drawer for a user is immediately recognizable and, where appropriate, the drawer does not need to be opened when it is recognized that the content is not available in the drawer.

Two exemplary embodiments of the invention are described with reference to FIGS. 1 and 2. From the detailed description of these specific embodiments, there are also other general features and advantages of the present invention. Show it:

In the interior 3, a storage compartment 6 is further attached. The storage compartment 6 has a closing cover 7. The closing cover 7 comprises a mechanical

Ventilation device 8, which may have an elastic wall portion 8a. By pressing the mechanical ventilation device 8, or the elastic wall portion 8a, the volume in the storage compartment 6 is reduced, so that an overpressure is created. If the overpressure exceeds a minimum size, a valve lip 9 is opened and air can escape from the storage compartment 6 into the interior 3. The valve lip 9 closes after releasing the elastic wall portion 8a again and the volume of the storage compartment 6 increases again due to the relaxing elastic wall portion 8a, whereby a negative pressure in the storage compartment 6 is generated.

At the storage compartment 6, a pressure-opening lock 12 is also provided. The pressure-opening lock 12 can be operated by pressing the elastic wall portion 8a to vent and / or aerate the drawer 6. The elastic wall section 8a can be integrated in the closing cover 7, as shown in the present exemplary embodiment. In particular, the elastic wall section 8a can be arranged centered in the closing cover 7.

In the case of the present second embodiment shown in FIG. 2, the storage compartment 6 is designed as a drawer 6a. The drawer 6a is extendable stored in the household refrigerator 1. The drawer 6a has a drawer front 7a. The drawer front 7a is formed as a flat plate. The drawer front 7a forms a vertical front wall of the drawer 6a. In addition, the drawer 6a has two side walls, a rear wall and a bottom. The drawer 6a is accessible from above. The

Drawer 6a is in the present embodiment on an underside 10 of the

Shelf 5 stored extensible. Between upper edges of the drawer 6a and the bottom 10 of the shelf 5, a seal 1 1 may be arranged. In order to be able to actuate the mechanical ventilation device 8 by a pressure force acting on the drawer 6a, the mechanical ventilation device 8 has the elastic wall section 8a, with which the drawer 6a can be vented. If pressure is applied to the elastic wall section 8a shown in FIG. 1 in the closed drawer front 7a, the elastic force becomes due to the pressure force

Wall section 8a of the mechanical ventilation device 8 deforms curved inward, so that an overpressure arises and the valve lip 9 is opened and air is pushed out of the drawer 6a in the interior 3 of the domestic refrigerator 1 out. The valve lip 9 closes after releasing the elastic wall portion 8a again and the volume of the drawer 6a increases again due to the relaxing elastic wall portion 8a, whereby a negative pressure in the drawer 6a is generated.

At the drawer 6a also a pressure-opening lock 12 is provided. The pressure-opening lock 12 can be operated by pressing the elastic wall portion 8a to vent and / or aerate the drawer 6a. The elastic wall section 8a can be integrated in the drawer front 7a as shown in the present embodiment. In particular, the elastic wall section 8a can be arranged centered in the drawer front 7a.
