Description

DESCRIPTION

Refrigerated or heated cabinet

The invention relates to a refrigerated cabinet or heated cabinet according to the preamble of claim 1.

From DE 112006000823 T5 such a refrigerating cabinet is known, with at least one refrigerated chamber, having a subspace or compartment divided by a shelf, for a receptacle, with an open top side. The receptacle is associated with a cover, which is supported on the subspace, the fastening means for the cover being configured such that it, in at least one state of open, releases an interstitium towards the receptacle and in a closed state closes the receptacle . The complete conduction of the cover is quite expensive and, in addition, the receptacle can only be opened in a gap, which, when there is a lot of moisture in the receptacle, is not sufficient to evacuate the moisture. In this case, climate compensation is also not optimally possible within the cold room and / or within the subspace.

From DE 102007005953 A1 a refrigerating cabinet is known which includes a receptacle with a cover resting on the cold room, which can be covered with a so-called diffusion layer. Under the diffusion layer the cover includes a plurality of openings, arranged distributed from the surface of the cover. To regulate the exchange of air, the openings can be closed by means of a perforated plate that can be moved. An air exchange can then take place only on the upper side of the receptacle cover, so that a good thorough mixing of the air or even uniform humidity of the air inside the receptacle cannot be ensured.

Document DE 19751 309 A1 discloses a refrigerator cabinet that includes a receptacle open at the top, closed by a cover plate and a cover. The cover can be deployed, to facilitate access to the interior of the container. In the rear area of the fixed cover plate, openings that can be closed have been made to regulate the humidity of the air in the receptacle. A similar configuration in a refrigerator cabinet is known from DE 296 11644 U1, in which a cartridge with a moisture filter is mounted on the fixed cover plate.

WO 2004/038312 A1 discloses a refrigerator cabinet that includes a receptacle open at the top, closed by a cover plate I. The cover plate in turn includes openings, which can be opened and closed in each case with flappers that can be folded down. In another embodiment, the cover plate can be lifted from the edge of the opening.

The invention thus formulates the objective of providing a refrigeration cabinet in which in an easy way an optimum adjustment of the humidity of the air within at least one refrigeration zone can be chosen and / or performed.

According to the invention, the objective is achieved by means of a refrigerated or air-conditioned cabinet with the characteristics of independent claim 1. Advantageous variants and improvements of the invention result from the following dependent claims.

The advantages that can be achieved by the invention are then that the air exchange can be adjusted in a simple manner, that is, the supply of air to the receptacle and the evacuation of air from the receptacle to the cold room. When the cover is closed, the receptacle is sufficiently separated from the cold room, which ensures uniformly high humidity in the receptacle. When the cover is open, a good inlet of the cold air flow into the receptacle is provided by raising at least one side of the cover and through the additional open openings of the cover, a flow outlet and / or an additional exchange of air between the cold room and the interior of the container. This is especially advantageous when the product to be cooled in the receptacle needs dry air. For this, on the cover, which can be lifted to open it, at least one opening can be closed. This additional opening or additional openings can be easily made in the cover, without having to keep additional movement space available for the cover itself in the openings refrigerating chamber, which.

In a convenient embodiment, the cover includes at least one plate that can be moved in or on the cover, to open and close the openings, which is essentially supported parallel to the extension of the cover and which by displacement to at least a first position it provides a closure and at least a second position an opening of the openings in the cover. In this way, a configuration of the closing means that occupies extremely little space is provided in a simple manner.

In an advantageous improvement, the guide means for guiding the cover are provided with sliding tracks, which interact with guide projections made on the plate, which are arranged fixed in the cold room. This means that the cover with the mechanism for displacing the position and the plate is arranged such that it practically cannot be removed inside the cold room. This always results in reliable operation of the cover, regardless of the position of the receptacle below. All directions and position indications refer to the operating position of the refrigerated or air-conditioned cabinet.

In a convenient refinement the plate is driven such that it can be moved by means of a groove / tongue joint in the cover. Thus the plate can also cause a lifting movement of the cover.

In another refinement, the sliding tracks are arranged in adapter strips, which are mounted on respective inner sides of the side walls of the cold room or cooling chamber. In this way, the inner surface of the side walls can be manufactured without inward conformations, since a sliding path with filigree can be made in a separate injection molding piece or milled part. It is also possible to constitute a variant or to subsequently equip the refrigerator cabinet with the corresponding functional cover. Together, the assembly is also simplified accordingly.

In an advantageous embodiment as a whole, the plate is conducted in the cover such that a displacement of the plate to open the openings also causes the cover to be lifted. With this, sliding the plate causes, in addition to the opening movement to open the opening of the cover, as a combined movement a lifting of the cover on at least one side. The user can thus originate both opening movements in a single operation. The closing of the cover takes place by the movement of the plate in the reverse direction, then the descent of the cover is carried out in a movement combined with the closing of the opening. To provide this form of combined movement, the control curve mentioned above is correspondingly configured.

In a convenient embodiment as a whole, the cover is supported such that it can rotate by means of a rotation axis, the rotation axis being arranged on the front side of the refrigerated or air-conditioned cabinet. This results in stable support and correspondingly an appearance of reliability.

In another development of the invention convenient as a whole, it is divided into the cold room, by means of fixed bottoms or which can be inserted, in at least two cooling or air conditioning zones located one above the other, the receptacle being arranged with the mobile cover on the minus a cooling or air conditioning zone below the bottom. Conveniently the aforementioned cover is provided for at least one so-called fruit and vegetable compartment or compartment for cold storage in the lower compartment of the cold store.

In another convenient embodiment, a handle is provided on the cover to move the plate along a direction of travel at least predominantly horizontal. This is how the user's attention is drawn to the possibilities of the so-called regulation of the humidity of the air by means of the visible operation handle, avoiding to a large extent incorrect operations based on the logic of the operation.

In an advantageous refinement, the handle is driven on the cover such that, by conduction, various fixing positions of the plate can be provided to provide different cross sections for opening the gaps and gaps between the cover and the edge of the container.

To this end, a configuration of sliding tracks with correspondingly acting spring means is provided, in order to cause a so-called push-pull movement of the handle and due to this an unequivocal movement of the plate and the cover. In addition, it is transmitted to the user and / or a pleasant tactile feedback of the operating operation is made available.

In another embodiment, the insertion movement or extraction movement of the operating handle on the cover is influenced by means of interlocking means, to cause an unequivocal opening position of the cover together with a tactile feedback to the user.

In an advantageous embodiment as a whole, the cover includes a configuration of holes with an arrangement of a plurality of openings, the plate including a configuration of holes corresponding to the previous one with an arrangement of a plurality of openings. In this way it is achieved that in a position of opening the configuration of holes of the plate coincides, at least predominantly, with the configuration of holes of the cover, being in the closed position the configuration of holes of the plate displaced in parallel with respect to to the configuration of cover holes such that the cover openings are closed. Due to the plurality of arranged holes distributed on the surface of the cover, a very good air exchange between the receptacle and the cold room can be achieved in the opening position.

In a convenient embodiment as a whole, the receptacle is constituted as a drawer that can be removed from the cold room, the cover being supported and / or driven to remain inside the cold room.

In another advantageous embodiment as a whole, the lubricant cover is provided on its side facing the edge of the opening. In this way the cover can rest on the upper edge of the receptacle when it is closed. In this position the receptacle can be easily removed or inserted from / in the subspace and / or cold room.

An exemplary embodiment of the invention is simply depicted in the drawings and will be described in more detail below. It shows in

Figure 1: an open refrigerator cabinet, viewed from the side of the door;

Figure 2: the receptacle with the cover in the closed position;

Figure 3: schematically, the receptacle in the cold room;

Figures 4, 5: the receptacle with cover in the open position;

Figure 6: the cover with plate and guide means in an exploded view;

Figure 7: the cover with guide means in a detailed perspective view;

Figures 8, 9: the means of guidance in different situations and

Figures 10, 11 12: an operation handle in different operating states.

Figure 1 shows by way of example a refrigerated or air-conditioned cabinet 1 in an overall view from the loading side. The refrigerated cabinet shown includes a refrigeration chamber 2, which in the embodiment shown is divided by fixed shelves 12 into several subspaces with the corresponding cooling or heated zones 2a, 2b and 2c. The complete refrigerating chamber 2 can be closed with the door 3. To generate the cold air, the refrigerating cabinet 1 has at least one refrigerating unit 5, which, through a cooling air outlet, causes an exchange of temperatures and thereby a cooling of the air in the cold room 2. The cold room 2 further includes several additional shelves 12, which are conveniently fastened such that they can be moved on the inner sides of the side walls 17a and 17b and are made such that they can be removed. Receptacles 4 are housed in the lower part in the cooling zone 2b and 2c, a cover 7 being associated with at least one receptacle 4, for the controlled adjustment of the humidity of the air inside the receptacle 4.

Figure 2 shows in a detailed view the receptacle 4, which is closed by the cover 7. The cover 7 is closed in the situation shown, which means that it rests on the upper edge 9 (Figures 4, 5) of the receptacle 4. The cover 7 is provided with a plate 13, which can be moved with respect to the cover 7 by means of spikes or projections 15 mounted laterally on the plate 13 on sliding tracks 14 of the adapter strips 20. The handle 22 can move the plate 13 parallel to the cover 7. In the shown closed situation, it can also be seen that only the openings 10a of the plate 13 are observed, but the surface of the cover 7a is below the openings 10a, whereby openings 10a and 10 are closed.

Figure 3 shows the closed container 4 in the cold room 2 and in the cooling zone 2b, which here is only schematically represented. It can be seen that the air L bathes the container 4 and there is no exchange of air between the interior of the container 4 and the cooling chamber 2 or the cooling zone 2. Inside the receptacle 4 there is thus a high humidity of the air when wet products are introduced there. Figure 9 also shows in detail an adapter strip 20 with the sliding track 14 as a sectioned perspective view, showing the sectioned cover 7 and the spindle 15. Here it can be seen that the spike 15 is in the lower, forward position of the ascending slide track 14. The cover 7 is then located on the edge of the opening 9 of the receptacle 4 and therefore closes the receptacle 4. The cover is supported on the front side of the refrigerator cabinet 1 by the pivot axis 21. The adapter strip with the sliding track 14 is mounted on the inner side of the side wall 17a and correspondingly 17b.

Figure 4 shows in a detailed view the receptacle 4, on which the cover 7 certainly rests frontally, but does not completely close the container 4. The lid 7 is therefore in the situation shown in the opening position, which means that it is held up from the upper edge 9 of the receptacle 4 and releases a gap 11. Furthermore, the openings 10 on the upper side of the cover 7 are open, since the plate 13 has a corresponding configuration of holes 10a ( Figure 6), which in the open position coincide with the configuration of the openings 10 of the plate. Since the plate 13 is displaced in the open position, the pin 15 mounted on the cover is located in an ascending area of the slide track 14, whereby in interaction with the cover 7, the edge of the edge is raised. opening 9. In figure 7 the adapter strip is shown in a vertical section of the longitudinal side, the ascending slide path 14 and the spike or projection 15 being conducted there can be seen. As already mentioned before, the pin 15 is fixedly connected with the plate 13 that can be moved, whereby a displacement of the plate 13 horizontally backwards causes the plate to be lifted due to the sliding path 14 upward. The plate 13 is driven by a tongue-and-groove joint 18, 19 through the cover 7 (figure 6), whereby a lifting movement of the plate 13 simultaneously raises the cover 7. In figure 7 it can also be seen that in the open position, in addition to lifting the plate 7, the hole configuration of the openings 10a of the plate 13 (figure 6) is also brought to coincide with the hole configuration of the openings 10 of the cover, with that all openings 10, 10a are open in this position, at least almost open or almost completely open. By means of the handle 22, the plate 13 is moved, the handle being held with a configuration of slide tracks 25 and spring means 24 and other functional parts in the receptacle 22a in the cover. Figure 8 also shows in detail an adapter strip 20 with the sliding track 14 as a sectioned perspective view, showing the sectioned cover 7 and the spike 15. In this regard it can be seen that the spike 15 is, based on the track of ascending slide, in the upper, rear position. The cover 7 is then lifted or distanced from the edge of the opening 9 of the receptacle 4 and releases, at least in the rear area, the gap 11. The cover 7 is supported on the front side of the refrigerator cabinet 1 by means of the rotation axis 21. In a convenient embodiment, the adapter strips 20 are fixed to the side walls such that they can be released, whereby the complete cover configuration can be easily removed with the adapter strips 20 of the cold room or subspace and also be placed new.

The lower side of the cover 7 is provided here, in an embodiment of sliding elements 7b, preferably with a Teflon® coating or bands of silicone material, which provide the contact area with the edge of the opening when the cover 7 is closed. In this way, the receptacle 4 of / in the refrigerating chamber 2b, 2c can also be easily removed or inserted when the cover 7 is closed. Furthermore, the cover can rest in the closed state at the edge of the opening in a sealed or at least almost airtight manner.

Figure 5 shows the container 4 in the open situation in the cold room 2 or in the cooling zone 2b, which is shown here only schematically. It can be seen that the air flow L enters the container 4 through the gap 11 and there is an exchange of air between the interior of the container 4 and the cooling chamber 2 or the cooling zone 2b. The air exchange is further favored by the openings 10 being open, whereby the interior of the receptacle 4 is flown through, at least almost completely, and a very good air exchange occurs between the interior of the container and the cold room 2 or the cooling zone 2b. Inside the receptacle 4 there is thus a lower air humidity, whereby wet product can be dried to be refrigerated and / or product refrigerated can be cooled evenly, due to the flow of cooling air L passing through it.

Figures 10 to 12 show in detail the operation of the operation handle 22 to provide a so-called push-pull function to move the plate 13. Figure 10 shows the handle 22 in this regard, as corresponds to the open position of the cover 7. The handle 22 includes in the embodiment shown a fixed base piece 22b, which interacts with a push button 22a that can be moved thereon. The button 22a is coupled with the plate 13 by means of coupling 22c (Figure 6). It can also be seen that the base piece 22b has a sliding track 23 and a guide track 26b configured as an elongated hole. By means of pressure springs 24, the button 22a is supported on the rear side of the base piece 22b, whereby the button 22a preferably moves out of the base piece 22b. The button 22a includes at least one guide pin 26, to drive it with stability and reliability within the base piece 22b. In addition, the button 22a is provided with a ratchet 25, which is driven by the slide track 23 and which can set the button 22a in the retention positions 23a, 23b, 23c provided in the track. In the situation shown, the ratchet 25 is in the retention position 23a.

Figure 11 shows the handle 22 for the so-called semi-open position of the cover 7. It can be seen that the ratchet 25 is in the central retention position 23b and thereby keeps the button 22a in the central position. The plate 13 coupled with the button 22a (Figure 6) is here in a position such that the hole configuration of the plate 13 does not completely cover the hole configuration of the cover 7 and the openings 10 are partially closed.

Figure 12 shows the handle 22 for the so-called open position of the cover 7. It can be seen that the ratchet 25 is in the last holding position 23c and thereby keeps the button 22a in the outer position. The plate 13 coupled with the push button 22a (Figure 6) is then in a position such that the hole configuration of the plate 13v completely covers the hole configuration of the cover 7 and the openings 10 are completely open. In order for the ratchet 25 to travel the slide path, it is coupled laterally with the button 22a, referred to the driving direction B, such that it can move or rotate. Due to the recovery force of the spring means 24, the button 22a can be moved by pressing from a holding position to the next holding position. The recovery of the button 22a or the arrival at the corresponding holding position is provided by the spring means 24.

As for the realization of the handle 22, it should be noted that the slide path 13 can be supported on the movable part 22a and the ratchet 25 on the base piece 22b.
