Description

The invention relates to a device for Dämmschichttrocknung, with a lower part and a detachably supported upper part, wherein one of the two parts for the purpose of forming an electrical contact a spring contact and the other of the two parts has a cooperating with the spring contact in the final assembled state of the two parts contact point wherein the contact point is formed on an upper side of a base element facing the one part, wherein the spring contact is arranged within a volume space provided by a recess corresponding to the base element.

Modern building methods provide an insulation of the floor, wherein typically an insulating layer between an underbody, such as a cement floor, and an upper floor, such as a screed floor, is arranged. To form such an insulating layer a variety of insulating materials can be used, such as polystyrene or glass fabric.

As a result of an unwanted leakage of water, for example due to pipe breakage, water damage can occur due to the fact that water also accumulates in the intermediate space between the underbody and the topsoil, which leads to wetting of the insulating material forming the insulating layer. Depending on the insulation used, it may possibly even come to a real sucking of leaked water through the insulation material.

In order to avoid a costly dismantling and reconstruction of the floor to eliminate such water damage, it is known from the prior art to make a Dämmschichttrocknung, for example by means of a device for insulating drying, as it is known from DE 10 2015 005 565 A1 is known.

Basically, two different process variants can be used in the insulation drying, namely on the one hand the so-called overpressure process and on the other hand the so-called vacuum process. In the overpressure method, dry, heated air is blown into the insulation layer through openings specially introduced into the topsoil and the intermediate layer, which then accumulate with the moisture from the insulation layer and over Edge joints and / or relief openings escapes up into the room where it is dried by means of dehumidifying units installed in the room. However, the vacuum method has proved to be more effective. In this method, no air is blown through the openings provided for this purpose in the space between the bottom and topsoil, but rather sucked there moist air located. For this purpose, a vacuum pump, for example, in the embodiment of a suction motor is provided, which is fluidly connected via a corresponding tubing to existing or prepared for this purpose openings in the topsoil. The moist air extracted by means of the vacuum pump is typically supplied to a water separator in which the water contained in the moist air is separated off. As a result of the moist air extraction created in the insulation layer, a negative pressure, which compensates due to trailing air by open edge joints and / or provided for this discharge openings again. It can be provided to accelerate the drying process additional dehumidifiers, which serve to dry the trailing air.

In the device according to the DE 10 2015 005 865 A1 It is a device for drying the insulation by means of vacuum, that is by means of negative pressure. The device has a lower part on the one hand and a top part on the other hand, wherein the upper part in the final assembled, ie ready-to-use condition is detachably supported by the lower part. In the intended use, the upper part is arranged on the lower part.

The upper part houses in particular the vacuum pump and a device electronics unit. For this purpose, the upper part provides a housing, which is divided into two compartments, wherein the first compartment serves as an engine compartment of the at least partially receiving the vacuum pump, whereas the second compartment for receiving the device electronics unit provides a space serving as an electronics space volume space.

The device base houses a vacuum chamber in which a water separator is arranged. In the intended use case, it comes as a result of operation of the vacuum pump to form a vacuum in the vacuum chamber, resulting in a suction of moist air from the hose-lined with the insulation layer. At the water separator, the water contained in the moist air is separated, which then accumulates in the vacuum chamber.

By means of a pump arranged in the vacuum chamber, the water accumulating in the vacuum chamber during operation is pumped off depending on the filling level.

The subdivision into the upper and lower part provides in particular the advantage that the device electronics unit accommodated by the upper part is largely moisture-decoupled from the vacuum chamber which absorbs water in the intended use.

The upper part of the device has a mains connection, which is in the normal operating conditions by means of a corresponding current-carrying cable in electrical connection, for example, with the public power grid. All device-internal electrical consumers are coupled in the final assembled state of the device to the device-internal power supply, including the housed by the lower part of electrical consumers, in particular arranged in the vacuum chamber pump. In order to form an electrical contact between the lower part and the upper part, a spring contact and a contact point cooperating therewith are provided, wherein the spring contact of the one of the two parts and the contact point of the other of the two parts is provided. In the final assembled state of the upper part and lower part of the spring contact and the contact point come into electrical contact, as a result, the housed by the lower part electrical loads are electrically connected to the device-internal power supply of the upper part.

From the prior art is according to the WO 2005/039375 A1 Furthermore, a dry and / or wet vacuum known, which has a body to which a motor can be interchangeable arranged. The body includes a steam generator, wherein a plug is provided for the power supply of the steam generator. For contacting this plug is a socket, which is designed as part of the interchangeable arranged on the body motor. The motor is powered by a cable. In the assembled state of engine and body, the motor is therefore used as an intermediate component to power the body.

Although the above-described construction has proven itself in everyday practice, there is room for improvement. In particular, it has been shown that the spring contacts formed on the upper part according to the prior art can be affected in particular due to mechanical stresses, which is in the worst case can lead to a proper contact between the upper and lower part is no longer guaranteed safe. It is therefore an object of the invention to further develop a device of the type mentioned in that constructive secure electrical contact between the upper and lower part is guaranteed, and this at the same time improved assembly and disassembly possibility of upper and lower part.

To solve this problem, a device of the type mentioned is proposed with the invention, which is characterized in that the lower part a non-contact second socket element is arranged, wherein the upper part provides a second, cooperating with the second base member recess.

To form an electrical contact between the upper part and lower part come in a conventional manner, a spring contact on the one hand and a cooperating contact point on the other hand for use. It is provided that the contact point is provided by a base element. In this case, the contact point is formed on the upper side of the base element, which faces the other part in the final assembled state. In this case, however, it is preferred that the lower part provides the base element, so that the contact point provided by the base element is formed on the upper side of the base element facing the upper part.

The spring contact is thus arranged within a volume space. Thus, the contact pin is advantageously deepened protection, which ensures an effective protection against mechanical loads in particular in an advantageous manner.

The volume space receiving the spring contact is provided by a recess which is formed corresponding to the base element. Thus, the recess providing the volume space serves as a guide aid for the base element, which completely accommodates the base element in the final assembled state.

Of course, plug-in systems as such are not unknown from the prior art. For example, the DE 196 04 346 A1 a cordless power tool with an interchangeable absorbed by a housing energy storage. In this case, contacts for pluggable electrical connection with mating contacts on the housing are on the housing Energy storage provided. From the US 2016/0218446 A1 Furthermore, a plug connection for signal transmission between a portable computer on the one hand and a monitor unit which can be arranged thereon is known on the other hand.

The previously known devices for contacting a rechargeable battery and / or a monitor unit are therefore not applicable to a generic device for Dämmschichttrocknung because the application is another. Thus, a proper use of a generic device takes place under damp conditions. In addition, the upper part to be contacted with the lower part of the device can not be handled on the user side in a simple manner, such as a one-hand battery and / or a one-hand laptop monitor.

The construction according to the invention also provides the synergistic effect that is provided by the enclosure of the spring contact in the volume space providing recess safe protection against mechanical external force effects on the one hand and that a guide is given by the interaction of recess and base element on the other hand, which guide help the user serves to align the upper part arranged detachably on the lower part in the correct position in relation to the lower part in case of assembly. An incorrect assembly by a twisted in relation to the lower part arranged on the lower part upper part can be safely avoided.

According to the invention, it is provided that a contact-point-free second base element is furthermore arranged on the lower part. This second base element cooperates with a second recess provided by the upper part. This embodiment serves a further coding protection and a better, because biaxial leadership. Consequently, in the case of installation, not only is there a guide via the base element and the associated recess, but also via the second contact element-free base element and the second recess cooperating therewith.

The volume space provided by the recess according to a further feature of the invention exceeds the spring contact in the height direction. The spring contact is thus completely absorbed by the volume space and does not protrude out of it. As a result of this embodiment, it comes in the case of assembly initially to a Immersion of the base member in the recess, before then accommodated by the volume space of the recess spring contact is in operative connection with the contact point provided by the base member. Consequently, there is initially a guided by the recess insertion of the base member instead of in the recess, which unwanted tilting and misalignment of the upper part are avoided on the lower part. As a result, a proper contact of the contact point is ensured by the spring contact.

The base element is preferably arranged on the lower part according to a further feature of the invention. It is provided that the base element protrudes in the height direction beyond the upper edge of the lower part facing the upper part. The base element thus forms a projection formed to the upper peripheral edge of the lower part. The volume space provided by the recess of the upper part accordingly represents a recess in the form of a depression into which the base element engages in the final assembled state. Because of this recessed embodiment, the already above-described protective recess arrangement of the spring contact.

The base element has according to a further feature of the invention a cross section of the circular shape deviating configuration. This serves an additional coding protection. In particular, it is not possible in such an embodiment, the upper part relative to the lower part to rotate about a device vertical axis, as soon as the base element is immersed in the cooperating recess.

According to a further feature of the invention it is provided that the upper part has a base plate facing the lower part, which has a breakthrough opening into the volume space provided by the recess.

The upper part is preferably encapsulated and has a bottom plate facing in the final assembled state base plate. This base plate is equipped with a breakthrough, in which opens the spring contact accommodating volume space. In the final assembled state, the base element consequently reaches through the opening formed on the base plate side and protrudes into the volume space located behind it, starting from the base element.

The breakthrough opposite a volume space limiting wall is provided which carries the spring contact. As a result, there is an overall extremely robust construction that is largely protected from external influences.

The embodiment of the invention takes into account in particular the fact that the upper part is detachably arranged on the lower part. Because by the protective-deepened arrangement of the spring contact ensures that it can not be damaged by bending, for example, that an upper part separated from the lower part is handled improperly, for example, that it is placed on its bottom part in the final assembled state opposite base plate. At the time of the DE 10 2015 005 865 A1 previously known construction has such a placement of the upper part alone by the weight of the upper part led to an unwanted application of force to the spring contact.

The invention further proposes an apparatus for drying an intumescent by means of a vacuum, with a vacuum chamber accommodating a water separator and a suction motor serving to form a vacuum in the vacuum chamber, the suction motor being at least partially disposed within a housing providing an engine compartment, the housing being two Compartments and wherein the first compartment provide the engine compartment and the second compartment a volume space for receiving a device electronics unit, wherein between the volume space and the vacuum chamber, a fluidic connection is formed.

The volume space provided by the second compartment of the housing serves as the electronics space for accommodating the device electronics unit. In order to protect the device electronics unit from accidental damage by external influences, in particular from contact with moist air and / or water, the compartment accommodating the electronics compartment is largely dense, in particular designed to be splash-proof. However, as a result of this structural measure for the protection of the electronic unit of the appliance, it is disadvantageously obtained that cooling of the appliance electronics unit which becomes warm in the event of operation is not permitted due to the lack of possibility of draining hot air. To make matters worse in this context, that the second compartment adjacent to the first compartment of the housing absorbs the suction motor at least partially, so that from Saugmotor outgoing waste heat can contribute to an additional heating of the device electronics unit. The result is also in the intended use, an operation of the device electronics unit at a relatively high temperature level, which negatively affects the life and reliability.

The embodiment of the invention provides a remedy, because it allows the invention provided fluidic connection between the volume chamber and vacuum chamber cooling the unit electronics unit, without having to forego a largely dense, that is in particular splash-proof design of the volume space providing compartment. The embodiment according to the invention thus provides the synergistic effect that the electronics compartment providing compartment for protecting the device electronics unit received constructive largely dense, especially designed splash-proof and this while providing cooling for the unit electronics unit, so that adverse effects due to a case of operation to high Temperature levels are excluded. Thus, the reliability and life of the device according to the invention is increased, on the one hand by the fact that the housing electronics unit is arranged protected within the second compartment, and on the other hand, that a heat dissipation from the second compartment is allowed, resulting in a cooling of the unit electronics unit result Has.

In the intended use, a vacuum is formed in the vacuum chamber by means of the suction motor. The vacuum chamber is in turn connected via a corresponding tubing with the insulating layer to be dried in fluidic connection. Due to the vacuum formed in the vacuum chamber during operation, moist air is sucked out of the insulating layer to be dried and fed to the vacuum chamber via the tubing. Here then takes place by means of the water separator, a separation of water from the humid air. The dehumidified so far air is then discharged via a corresponding device outlet opening to the atmosphere surrounding the device and / or directed into the open air. This created by the device air flow is also referred to as process air.

According to the invention it is now provided that the basically dense, ie in particular spritzwassergeschützt trained compartment, the electronics compartment provides, is in fluid communication with the vacuum chamber. This fluidic connection ensures in the case of operation that due to the resulting vacuum in the vacuum chamber air is sucked from the second compartment, which air is then mixed in the vacuum chamber in the process air flow with. Since a negative pressure is formed within the vacuum chamber during operation, only air from the second compartment is always transferred into the vacuum chamber, but not in the opposite direction, moist air is transported from the vacuum chamber into the second compartment. The device electronics unit is so far systemic protected against unwanted moisture entry from the vacuum chamber in the second compartment. Although the second compartment is basically tight, that is, in particular designed to be splash-proof, it is not hermetically sealed. In the case of a vacuum-related suction of air from the second compartment, air can then flow from the outside into the second compartment via assembly gaps and cracks, which leads to a pressure equalization within the second compartment.

The embodiment of the invention allows in a structurally simple way heat dissipation from the unit housing the electronics unit second compartment. There is no risk of unwanted moisture entry into the second compartment, since the heat dissipation is achieved due to vacuum, which makes an overflow of air in the opposite direction, that is from the vacuum chamber out into the second compartment impossible.

The fluidic connection between the second compartment and the vacuum chamber may be formed in a variety of forms per se. However, it is particularly preferred that the housing terminates on the vacuum chamber side with a wall which has a passage opening for forming a fluidic connection between the volume space and the vacuum chamber. Due to the design of the vacuum chamber side formed wall is provided anyway. To form the fluidic connection between the volume chamber and the vacuum chamber, an opening is introduced into this wall, which is present anyway. In such a passage opening may be, for example, a bore having a diameter between 10 mm and 2 mm, preferably between 6 mm and 3 mm. The formation of a passage opening as fluidic connection is particularly easy to design manufacturer and therefore proves to be in the making as a particularly cost-effective. Alternatively, instead of a passage opening, a tubing may also be provided, if appropriate one which is installed either inside the device or also outside the device.

The diameter of the passage opening is preferably dimensioned such that always at least a small flow of air from the second compartment can take place into the vacuum chamber. To ensure this, it is also possible to provide a plurality of passage openings, for example three passage openings or even more.

The volume space providing housing is arranged according to a further feature of the invention in the height direction above the vacuum chamber. The air flow from the second compartment into the vacuum chamber is thus favored. In particular, no labyrinth guide and / or the like is provided which could clog. The preferably formed as a bore fluidic connection connects the volume space with the vacuum chamber rather directly.

For additional protection of the device electronics unit optionally a valve closing off the passage opening, for example a poppet valve, can be provided which opens from the application of a specific vacuum within the vacuum chamber. As long as the vacuum is not reached within the vacuum chamber, the passage opening is closed by the valve. This optional measure provides added security against unwanted moisture application to the second compartment.

The vacuum chamber side of the housing provided wall is preferably plate-shaped and carries the suction motor. It is provided for a particularly compact design of the device according to the invention, that the wall has an opening through which the suction motor extends at least partially into the vacuum chamber. Thus, the suction side of the suction motor is disposed within the vacuum chamber, whereas the pressure side of the suction motor projects into the engine compartment provided by the housing.

According to a further feature of the invention, it is provided that a fluidic connection is formed between the engine compartment and the vacuum chamber.

In this way, the above-described effect is also used for cooling the engine. Although the naturally aspirated engine is exposed to its own cooling air flow, an additional cooling effect can also be achieved for the engine by forming a fluidic connection between the engine compartment and the vacuum chamber. The compartment forming the engine compartment is at least partially filled with a sound insulation material in order to be able to ensure a minimized noise nuisance during operation. Nevertheless, in order to be able to allow a removal of hot air from the engine compartment into the vacuum chamber in the event of the formation of a fluidic connection between the engine compartment and the vacuum chamber, the soundproofing material preferably provides air ducts. These can either be present as channels introduced into the sound insulation material or can result from the fact that the sound insulation material as such is porous and thus permeable to air.

Fig. 1 can be seen in a schematic view from the front of an inventive device 1 for Dämmschichttrocknung. The device 1 has a known manner on a lower part 2 on the one hand and on an upper part 3 on the other. In this case, the upper part 3 is detachably arranged on the lower part 2.

The lower part 2 houses a vacuum chamber not shown in the figures. This is the user side of the top with removed top 3 accessible.

For a proper assembly, the upper part 3 is placed from above in the direction of the arrows 20 on the lower part 2. A positionally secure arrangement of the upper part 3 on the lower part 2 can be achieved by clamping and / or screwing means, not shown in the figures.

The upper part 3 has a network connection not shown in the figures. This is in the intended use in electrical connection with a power source, such as the public power grid. All provided by the device 1 electrical loads are coupled in the intended use case to the housed from the upper part 3 device-internal power supply, including the housed by the lower part 2 electrical consumers, such as a arranged in the vacuum chamber pump.

For electrical contacting of upper and lower part arranged on the upper part 3 spring contact strip 5 and a hereby cooperating and arranged on the lower part 2 contact point strip 7 are provided in the illustrated embodiment. In the final assembled state, the spring contacts 4 of the spring contact strip 5 are electrically contacted at the respectively associated contact points 6 of the contact point strip 7, so that a current flow from the power connection of the upper part 3 to the electrical loads of the lower part 2 can take place.

How Fig. 1 can recognize, the lower part 2 has a base element 8, which protrudes in the height direction 12 on the upper part 3 facing the peripheral edge 13 of the lower part 2 addition. This base element 8 has a the upper part 3 facing Top 9. This top side 9 of the base element 8 provides the contact points 6 of the contact point strip 7.

The base member 8 in the final assembled state of the device 1 opposite to the upper part 3, a recess in the form of a recess 10 is provided, which provides a volume space 11. This volume space 11 is accessible through an opening 15 in the base plate 14 of the upper part 3. At the opening 15 opposite and the volume space 11 delimiting wall 16, the spring contacts 4 of the spring contact strip 5 are arranged. In the final assembled state, the base element 8 engages in the recess 10, so that it comes to form an electrical contact between the spring contacts 4 and the contact points 6. In this case, at the moment of contacting the spring contacts 4 spring back in accordance with the arrows 21, whereby a secure contact of the spring contacts 4 is ensured at the associated contact points 6.

The FIGS. 2 and 3 can be seen in detail in a schematic representation of the formation of base element 8 and recess 10 in detail.

As is clear from the FIGS. 2 and 3 In particular, the recess 10 serves the base element 8 at the moment of merging, that is, during assembly of the upper part and lower part as a guide. The base 8 emerges for the purpose of contacting the contact points 6 provided by the base element 8 with the spring contacts 4 in the volume space 11 provided by the recess 10. The lateral boundary wall of the recess 11 serves as a guide surface for the base element 8.

As in particular the representation after Fig. 2 can be seen, the provided by the recess 10 volume space 11 exceeds the spring contacts 4 in the height direction 22 of the spring contacts 4. This ensures that it comes to contacting the spring contacts 4 with the associated contact points 6 only when the base element 8 in the recess 10 already immersed and applied to the serving as a guide surface side wall of the recess 10. An unwanted tilting is prevented. In addition, a torsion protection is given, because the base element 8 and the associated recess 10 are formed in cross-section deviating from the circular shape, as in particular the FIGS. 4 and 5 reveal. This is in the Secured moment of immersion of the base member 8 in the recess 10, the upper part 3 and lower part 2 can not be rotated relative to each other.

As the FIGS. 4 and 5 can be seen further, with respect to the spring strip 5 a total of four spring contacts 4 and also four contact points 6 are provided with respect to the contact point strip 7. For screwing the spring contact strip 5 with the upper part or for screwing the contact point strip 7 with the lower part 2 corresponding holes 19 are provided.

As is apparent from the above illustration, the inventive design of recess 10 on the one hand and base element 8 on the other hand serves to protect the spring contacts 4 protectively and provide a guide to the simplified orderly arrangement of the upper part 3 on the lower part 2.

Protective for themselves show the FIGS. 6 and 7 a preferred further development of the device according to the invention, wherein it is provided that the device has a housing which is divided into two compartments, wherein a first compartment an engine compartment and a second compartment provide a volume space for receiving a device electronics unit, wherein between the volume space and one of a fluidic connection is formed in a vacuum provided a water separator of the device. For this purpose as follows in detail.

Fig. 6 can be seen in a schematic view from the front of an inventive device 101 for insulation drying. The device 101 has, in a manner known per se, a lower part 120 on the one hand and an upper part 121 on the other hand. In this case, the upper part 121 is detachably arranged on the lower part 120.

The lower part 120 houses a vacuum chamber 102. This is the user side accessible from the top with the top 121 removed. Within the vacuum chamber 102, a water separator 103 is arranged.

For a proper assembly, the upper part 121 is to be placed on the lower part 120 from above against the height direction 117 downwards. A positionally secure arrangement of the upper part 121 on the lower part 120 can by Spann- and / or Bolting 125 can be achieved as shown in Fig. 7 can be seen schematically.

The device 101 further has a suction motor 104. This is at least partially disposed within a motor space 111 providing housing 107 of the upper part 121. In particular Fig. 6 can recognize, the housing 107 has two compartments 108 and 109, which are separated by a separating plate 110 from each other. In this case, the first compartment 108 provides the engine compartment 111 and the second compartment 109 a volume space 112 for receiving a device electronics unit 113.

The housing 107 of the upper part 121 has an upper wall 116, a side wall 115 and a wall 120 facing the lower part 120. This wall 114 is plate-shaped. It has an opening through which the suction motor 104 projects into the vacuum chamber 102. With its pressure side 105 of the suction motor 104 is thus arranged in the upper part 121 and thus with its suction side 106 within the vacuum chamber 102 of the lower part 120. This advantageously provides a very compact construction, in particular in the height direction 117.

The vacuum chamber 102 has not shown in the figures ports for a tubing. At least one hose for incoming process air and one hose for outgoing process air are provided.

In the intended use, a vacuum is generated by means of the suction motor 104 within the vacuum chamber 102. As a result, process air is sucked in via the at least one inlet hose. The process air is humid air, which comes from the insulating layer to be dried, which is fluidly connected to the device 101 via the tubing. The moist process air flows in accordance with the arrows 122 in the vacuum chamber 102 a. There it comes with the help of the water separator 103 to a separation of water from the humid air. The dried process air so far is released via the at least one process air discharge hose in the atmosphere surrounding the device 101, possibly also to the outside.

According to the invention, it is provided that the volume space 112 housing the housing electronics 113 is in fluidic connection 118 with the vacuum chamber 102. In the illustrated embodiment, this fluidic connection 118 is achieved by three passage openings 119, which are bores formed in the wall 114, as shown in particular the illustration Fig. 7 lets recognize.

The fluidic connection 118 ensures in the case of operation due to the vacuum forming in the vacuum chamber 102 that is sucked out of the volume space 112 in accordance with the arrow 123 air, which is then mixed in the vacuum chamber 102 with the process air and discharged. By this air discharge from the volume space 102, a cooling of the device electronics unit 113 is achieved by heat dissipation in an advantageous manner.

The second compartment 109 of the housing 107, which provides the volume space 112, is substantially dense in order to protect the electronics unit 113, in particular, splash-proof. Nevertheless, the compartment 9 is not hermetically sealed off from the atmosphere surrounding the device 101, so that air can flow into the volume space 112 through device slots, expansion joints, screw holes and / or similar openings in correspondence with the arrows 124, so that there is compensation for the result the vacuum created by the air suction comes.

The embodiment according to the invention advantageously makes it possible to make the volume space 112 dense for the most part, which serves to protect the device electronics unit 113. Unintentional dust and / or water entries in the second compartment 109 are thus largely excluded to protect the device electronics unit 113. Nevertheless, despite this largely dense configuration of the volume space 112, a cooling of the device electronics unit 113 is ensured by hot air removal, which increases the reliability and longevity of the device 101. In this case, the removal of hot air from the volume space 112 takes place due to the fluidic connection 118 between the volume space 112 and the vacuum chamber 102.

Since a removal of hot air from the volume space 112 into the vacuum chamber 102 takes place with an adjacent vacuum within the vacuum chamber 102, an overflow of moist air from the vacuum chamber 102 into the volume space 112 is excluded. Nevertheless, a one-way valve can optionally be provided which opens the fluidic connection 18 only when a specific vacuum is present within the vacuum chamber 102.
