Description

Description of storage compartment module

The invention relates to a storage compartment module, in particular in the form of a drawer for dental workplaces, which is arranged below a table top and is constructed from a frame device and a drawer device which is mounted on the frame device.

Such modules are used in workplaces that are equipped with a single-place extraction system. In such a conventional structure, for. B. according to DE-U-79 31 254, a support frame is arranged on the underside of a worktop, in which a filter drawer is insertably mounted. The filter drawer is completely filled by a dust filter bag located therein and has a connection opening for a suction funnel on the front panel. On the back of the filter drawer is arranged a bulky housing which projects approximately at a right angle from the drawer and which essentially comprises a motor with a turbine and an electronic control part. The electronic control part of this motor and control part housing is coupled to a toggle switch arranged on the front panel, with which the single-place extraction system can be switched on or off. In an alternative embodiment, instead of a suction funnel arranged on the front panel, a flexible suction hose can also be arranged on the back of the filter drawer. Furthermore, the support frame of the filter drawer can be constructed in such a way that additional waste drawers can be used below the filter drawer.

A disadvantage of such a filter drawer arrangement limited to single-place extraction systems is that the motor and control part housing flanged to the rear of the filter drawer limits the legroom of a person working at such a workstation and thus makes sitting longer uncomfortable. In addition, such heats Motor arrangement on the dental work station and there is often still an odor nuisance, since the exhaust air is returned to the work area. Furthermore, a filter that is arranged horizontally forms a larger inactive part than an approximately vertically arranged filter, especially at the clamping point. Another disadvantage is that the entire arrangement consists of two parts, namely a filter drawer arrangement and a motor and control part housing, which makes assembly difficult and therefore more time-consuming and expensive.

US-A-5,033,238 describes a work table for dental technicians, in which a hand grinding device and a suction device are coupled via two control parts such that the first control part specifies the required speed of the milling head, while the second control part determines the suction power as a function of this speed, which ensures optimal coordination. While the hand grinding device together with the integrated keyboard device is arranged on the worktop, the control parts of the processing device and the suction device are arranged in the area of the work table near the floor.

A disadvantage of this arrangement is the relatively complicated structure, since the electronic control parts arranged in the vicinity of the floor in a work table have to be coupled to a hand-held grinding device by means of lines leading upwards. Furthermore, an elaborately installed suction pipe structure is necessary in order to also lay a suction pipe from bottom to top in such a way that the suction funnel is optimally attached to the workplace.

Accordingly, the object of the invention is to create a drawer-shaped storage compartment module, in particular for dental workplaces, which has a compact and simple structure, is easy to assemble and can be connected to central suction systems. This object is achieved by a storage compartment module with the features of patent claim 1.

Accordingly, an electronic control part for a processing device is arranged in the immediate vicinity of a central suction system connection element in a drawer device, this central suction system connection element being arranged by the

Drawer device is arranged leading. Functional units such as e.g. Tools and / or processing aids can be arranged to save space on the worktop. The compact arrangement of functional units, central suction system connection element and electronic control unit in a single drawer device provides storage compartment modules that can be quickly and easily converted or upgraded to the respective need. Furthermore, these storage compartment modules also allow a quick and, above all, simple connection to a central suction system, so that time-consuming retrofitting and assembly at the workplace are eliminated. If, for example, a dental technician has to switch from alloy work to milling work at his workplace in a dental laboratory, it is sufficient to replace a storage compartment module designed for alloy work with a storage compartment module designed for milling work, the storage compartment modules preferably being designed in such a way that they are connected to each other by the same connections Work place can be arranged within a laboratory.

Advantageous embodiments are the subject of the subclaims, in particular an electronic control part with a pressure detection device arranged on a central suction system connection element, which checks whether the necessary negative pressure required for powerful suction is generated in the suction line. Due to the immediate vicinity of the central suction system connection element and the electronic control part, the pressure detection device can be arranged with an extremely short connection to the electronic control part, so that no complicated structure for pressure measurement is necessary, which contributes significantly to facilitating the vacuum determination. Furthermore, in a preferred embodiment, the electronic control part controls a control valve with which a closure valve arranged in the central suction system connection element can be set into an open or closed position. In addition to the electronics control part and the central suction system connection element, all other functional units that can be coupled to the electronics control part or to other elements, such as a blower for drying ceramic layers, can be arranged in the drawer device Compressed air nozzle with a first and second suction point as well as a technology module which is arranged in the drawer device manually or electrically extractable or extendable or which can also be manually or electrically pivoted out of the drawer device by means of a swivel joint.

Several exemplary embodiments are explained and described in more detail below with reference to the drawing. Show it:

Fig. 1 is a schematic front view of a

Table top arrangement, in particular for dental technician workstations, in which a storage compartment module is arranged below the table top;

FIG. 2 shows a side view of the table top arrangement of a dental technician work table according to FIG. 1;

FIG. 3 shows a plan view of a storage compartment module along a section shown in FIG. 2;

4 shows an embodiment in which a blower device is arranged in the storage compartment module;

5 shows an embodiment in which the storage compartment module is provided with a second suction point;

6 shows an embodiment in which a technology module can be displaced between guides in the storage compartment module; -5- Fiq. 7 shows an embodiment in which a technology module on the

Storage compartment module is pivotally mounted; and FIG. 8 shows an embodiment in which a filter element is arranged so that it can be pulled out in the storage compartment module.

1 and 2 show a table top 100, below which a storage compartment module is preferably arranged in the center and is composed of a frame device 1 and a drawer device 2. The drawer device 2 is arranged approximately flush with the front edge of the table top 100 and is preferably fastened to the frame device 1, for example by means of screws, as is indicated by the broken line in FIG. 2. However, the drawer device 2 can also be guided in the frame device 1, for example be mounted on guides in the manner of a drawer. FIG. 2 also shows how a connection piece 4a of a central suction system connection element 4 (see FIG. 3) to be discussed in detail is connected to a pipe socket 144 of a central suction system. Central extraction systems of this type are replacing more and more individual workplace extraction systems due to their more efficient application possibilities, whereby they are installed in separate rooms and no longer return the cleaned exhaust air to the work area. Of course, a frame device 1 would also be conceivable, which is constructed in such a way that it can be expanded downwards or laterally in order to arrange additional storage compartment modules or drawers below the table top 100. The storage compartment module can also be used with the

The frame device 1 can be permanently installed in the work table or the frame device 1 can be designed as part of the work table or the table top 100.

3 shows a plan view of such a storage compartment module along the section line AA shown in FIG. 2, in which, for reasons of clarity, only the respective connection areas of the central suction system connection element 4 are shown in section. In a In a preferred embodiment, an electronic control part 3 is arranged in the front right area of the drawer device 2. The electronics control part 3 is coupled via a line 53 to a pressure detection device 5, which is arranged on a central suction system connection element 4. This pressure detection device 5 measures the pressure prevailing in the suction line in order to start up a

Block processing device 10 when the negative pressure generated by a turbine of the central suction system is not sufficient for effective suction. This provides additional security that the workplace is being vacuumed properly, which reduces the stress to which the technicians are exposed at the workplace.

Furthermore, a connection 9 for a processing device 10 is coupled to the electronic control part 3 via a line 93. The connection 9 is preferably arranged in the rear 2a of the drawer device 2 to bring the processing device 10 from the rear of the work table, or through a recess in the table top 100, forward to the object to be processed, thereby preventing that Connection cable of the processing device 10 is in the way of editing a model.

Furthermore, the electronic control part 3 is coupled via a line 63 to a control valve 6, which is connected via a line 46 to a shut-off valve 4b arranged in the immediate vicinity of the control valve 6 on the central suction system connection element 4 and to one on the rear side 2a of the drawer device 2 Compressed air connection 8 is connected. If the processing device 10 is not actuated, the control valve 6, which can be, for example, a conventional 3/2-way valve, is in the open position for the compressed air admitted via the compressed air connection 8, so that the closure valve 4b is acted upon via line 46 with compressed air that it is in its closed position. For example, if a The switch located on the processing device 10 is actuated, the electronic control part 3 receives a pulse, on which the electronic control part 3 controls the control valve 6 via line 63. This causes the control valve 6 to be placed in its closed position so that the compressed air let in through the compressed air connection 8 is no longer allowed to pass. In this case, the closure valve 4b is vented via line 46, which is therefore in its open position, which enables suction at the workplace.

Furthermore, a mains connection 7 is arranged on the rear side 2a of the drawer device 2 and is coupled to the electronic control part 3 via a line 73. This ensures that all connections and cables run in the rear area of the drawer device 2. In addition, all connections are hereby permanently installed on the storage compartment module, preferably on the rear 2a, so that simple installation and removal is achieved.

The electronic control part 3 is also via a line 193 with a switch 19, which gives the operator a choice between automatic operation or continuous operation of the central exhaust system, via a line 203 with a reset switch 20 and via a line 223 with a Control lamp 22 coupled, which are all arranged in the front panel 2b of the drawer device 2. The arrangement is of course not limited to these elements 19, 20 and 22. So z. B. also provided additional connections, switches, etc. on the front panel 2b of the drawer device 2 and coupled to the electronics control part 3, but this is not shown here.

A central suction system connection element 4 is arranged in the immediate vicinity of the electronic control part 3, as shown in FIG. 3. In particular, the central suction system connection element 4 consists of a first one Connector 4a, a shutoff valve 4b, a silencer 4c and a second connector 4d. The first connection piece 4a is mounted in the back 2a of the drawer device 2 and is pluggable with the end protruding from the back of the drawer device 2 with a pipe socket 144 of a central suction system, while the other end of the first connection piece 4a is pluggable with one of the back 2a the drawer device 2 facing end of a closure valve 4b is connected. In the preferred embodiment of FIG. 3 shown here, the pressure detection device 5 is arranged between the first connection piece 4a and the closure valve 4b. The closure valve 4b is preferably a valve which can be closed by means of compressed air and which has a rubber sleeve in its interior. However, any other type of closure device which is well known to the person skilled in the art can also be selected, for example a slide mechanism which is coupled to the control electronics 3, but which is not shown here. Furthermore, the end of the closure valve 4b facing the front panel 2b of the drawer device 2 is pluggably connected to an end of a muffler 4c facing the rear 2a of the drawer device 2. The silencer 4c can have any structure which is well known to the person skilled in the art and which allows the air flow to be deflected, divided and braked. The end of the muffler 4c facing the front panel 2b of the drawer device 2 is finally connected to a second connecting piece 4d which is mounted in the front panel 2b of the drawer device 2. This second connecting piece 4d is preferably pluggably connected to an extraction funnel 145, as shown in FIG. 3, an arrangement in which an extraction funnel is screwed into the front panel 2b is also conceivable. The entire central suction system connection element 4 is preferably arranged in the drawer device 2 such that it is inserted at a distance from the floor between the first and second connecting pieces 4a, 4d of the drawer device 2. As can also be seen from FIG. 3, the compact arrangement of the electronic control part 3 and

Central suction system connection element 4, a free space 2c is formed in the drawer device 2, in which any type of additional functional units, such as e.g. Tools and processing aids can be arranged. These functional units can be coupled to data lines 23 or supply lines 24 of the electronic control part 3, the number of data and supply lines starting from the electronic control part 3 being arbitrarily high. Likewise, the arrangement of the electronic control part 3, the central suction system connection element 4 and all other devices arranged in the storage compartment module is not restricted to any position in or on the drawer device 2. Rather, these elements, which are matched to the individual need and application, can be arranged in or on them as desired, i.e. also several functional units next to or on top of each other.

4 shows such a processing aid, which is arranged in the free space 2c of the drawer device 2. There, a blower 21 is arranged in the drawer device 2 such that a front nozzle end 21a of the blower 21 protrudes from the front panel 2b of the drawer device 2 and thus enables the dental technician, for. B. Blow dry ceramic layers. In this case, a movement detector 40 can be arranged on the front panel 2b of the drawer device 2, which activates the blower 21 when an object to be processed is moved past it. The blower 21 and the motion detector 40 are preferably coupled to the electronic control part 3, which is not shown in more detail here. Furthermore, part of the central suction system connection element 4 is shown schematically in FIG. 4, which here merely forms a suction point, but could also be connected to a suction funnel. Fig. 5 shows a further possibility of utilizing the free space 2c in the drawer device 2, in which, in addition to the original central suction system connection element 4, which forms a first suction point 37, a suction element 27 opening into the central suction system connection element 4 is arranged, which is a second Forms suction point 29 and includes a closure valve 38. This second suction point 29 can be designed as a fine suction point in order to blow away, for example, the fine milling dust that is statically adhering to a model by means of a compressed air nozzle 36, which is preferably connected to the compressed air connection 8, which is then suctioned off via the suction element 27. In this case, the first suction point 37 is designed as a rough suction point for conventional suction situations and has a structure similar to that of the central suction system connection element 4. 5 also shows a motion detector 35, which activates both the compressed air nozzle 36 and the fine suction by means of the suction element 27, wherein the suction element 27 can be closed by means of the closure valve 38 or can be set for passage. Preferably, the closure valve 38 is also connected to the compressed air connection 8 or the motion detector 35 is coupled to the electronic control part 3, but this is not shown in more detail here.

Fig. 6 shows a further embodiment in which a technology module 18 is arranged in the left space 2c in the drawer device 2 in such a way that it is guided between two guide angles 14, the guide angles 14 being form-fitting in complementary recesses 17 of the technology - Intervene in module 18. The guide brackets 14 are fastened to the bottom of the drawer device 2 and can be arranged along the entire length (see FIG. 6) or only partially (not shown) along the technology module 18. Instead of the guide bracket 14 shown in FIG. 6, any other type of guide can also be selected, for example a flat or prism guide as an open guide or a dovetail guide as a closed guide. The technology module 18 is likewise not limited to the structure shown in FIG. 6, but can be arranged in the drawer device 2 in accordance with the respective need. The arrangement of more than one such technology module 18 is also possible. The technology module 18 can also be pulled manually out of the drawer device 2 or can also be provided or coupled with an electronic device which is well known to the person skilled in the art and which enables the technology module 18 in the manner of a CD recording carriage of a CD player to move out of the drawer device 2, for example by actuating a switch arranged on the front panel 2b of a drawer device 2, only the manual arrangement being shown in FIG. 6.

As shown in FIG. 7, the technology module 18 can also be arranged pivotably on the drawer device 2 by means of a pivot joint 16, as a result of which it can be pivoted out of the latter. The pivoting out can also be done manually or by means of an electronic arrangement. The technology module 18 can also be designed as a tool compartment or as a storage compartment for others

Operational tools serve. For example, the arrangement of a hand-held grinder work station in such a technology module 18, which is not shown here, is conceivable, which is in the inserted or retracted position of the technology module 18 in the parking position in the free space 2c next to the muffler 4c (cf. FIG. 3 ) and in the extended or extended position of the technology module 18 in the working position. This will Space saved on the worktop that can be used for other purposes.

Fig. 8 shows such a work station arranged in the drawer device 2, in which a filter element 26, which comprises a perforated sheet casing and an activated carbon filter (not shown) arranged therein, is telescopically arranged in a filter housing 32, which is connected to the central suction systems Connection element 4 is connected via a branch line. When mixing monomer solvents in a mixing vessel (not shown) placed on the perforated metal casing of the filter element 26, the resulting solvent vapors, which are heavier than the ambient air, fall down and are sucked out of the workplace through the holes in the metal casing of the filter element 26 . In this case, the telescopic filter element 26 can either be pulled out manually from the front panel 2b of the drawer device 2 via a flat guide 15, or it can be moved out electrically.

Another embodiment, not shown here, provides for the pluggable attachment of a model processing station, which comprises, for example, a end mill, to the front panel 2b of the drawer device 2, in which the pins of the model processing station serve both as a guide and on the other hand for electrical contacting.
