Description

Technical field

[0001] The invention relates to a portable hygiene station, in particular a cleaning station, for construction sites, especially for small construction sites. State of the art

[0002] It is common practice to install portable toilets on construction sites. Such portable toilets typically consist of a simple cubicle with a <abinentür auf, mittels derer ein Innenraum der Kabine wahlweise geöffnet und geschlossen werden kann. Als Sanitäreinrichtung ist eine Toilette und in besser ausgestatteten Kabinen eine Hygieneeinrichtung, wie beispielsweise ein Waschbecken, mit einem Wassertank ausgebildet. Der Fokus derartiger Toilettenkabinen liegt allerdings auf dem Bereitstellen einer Toilette und nicht dem Bereitstellen einer Hygieneeinrichtung.

[0003] Such a toilet cubicle is known, for example, from DE 20 2016 101 186 U1. The toilet cubicle described in DE 20 2016 101 186 U1 comprises a cubicle with a floor section, a ceiling section, corner posts extending between the floor and ceiling sections, and side walls, each arranged between two corner posts. One of the side walls is pivotally attached to one of the corner posts to allow access to the interior. Furthermore, the toilet cubicle includes a sanitary unit designed as a toilet with a water tank. The water tank is designed to be suspended from an end section of one of the corner posts by means of a bracket.

[0004] Furthermore, WO 00 / 36234 A2 shows a portable toilet cabin and DE20 2020 101 660U1 a mobile cleaning station for handwashing.

[0005] While existing toilet cabins, with their simple design, are quick and easy to deploy on construction sites, they are not adequately adapted to the conditions and needs of construction sites, especially small ones. Therefore, it would be desirable to develop a hygiene station better suited for use on construction sites. Description of the invention

[0006] The invention is therefore based on the objective of providing a hygiene station that eliminates the aforementioned problems and disadvantages of the prior art. In particular, it is an objective of the present invention to provide a hygiene station that is well suited for use on construction sites, especially small construction sites.

[0007] This problem is solved by the subject matter of independent claim 1. Further possible embodiments of the invention are specified in particular in the dependent claims.

[0008] The solution according to the invention comprises a portable hygiene station, in particular a cleaning station, for construction sites, especially small construction sites, which has at least one hygiene device and an insulated container in which the at least one hygiene device is arranged, wherein the insulated container has the following: an insulated housing which defines a usable space inside in which the at least one hygiene device is housed; and a container door which is hingedly connected to the insulated housing and by means of which the usable space of the insulated container can be selectively opened and closed, wherein an external water supply connection is provided on the insulated housing, wherein the hygiene device has at least one washbasin with a water outlet and a water drain, and wherein the portable hygiene station has a frost protection device which is arranged in the usable space of the insulated housing.

[0009] The hygiene station is characterized by its portability and transportability. It is therefore not tied to a fixed location and can be used at various sites. The hygiene station serves as a cleaning station, particularly for personal hygiene. Furthermore, it provides a water supply.

[0010] A small construction site is defined as one the size required for a single-family home. Here, the hygiene requirements, depending on the maximum number of workers, are the same as for larger construction sites. The sanitary containers available on the market are usually equipped with numerous washing stations, which are not needed on small construction sites. Therefore, their use is not economical.

[0011] An insulated container is understood to be a thermally insulated container. Specifically, this refers to a container designed with thermal insulation that reduces the transfer of heat energy in order to protect the usable space from excessive cooling. This can be achieved, for example, by a suitable covering arranged within a wall of the insulated container.

[0012] The housing of the insulated container can be closed using the container door. The hinge used for this purpose is preferably a pivot hinge, allowing the container door to be pivotally attached to the insulated housing. The insulated container separates the usable space from the external environment. The external water supply connection is located on one side of the insulated container, i.e., on the side facing away from the usable space. This water supply connection provides water to the hygiene equipment. A water supply hose can be connected to the water supply connection for this purpose.

[0013] The hygiene facility is a device used for cleaning, particularly personal hygiene. It is specifically not a sanitary facility primarily intended for the collection or disposal of bodily excretions. The hygiene facility is the washbasin, specifically designed as a handwashing basin. The washbasin is designed as an upwardly concave container. The water outlet can be a fitting for the metered dispensing of hot and / or cold water. The water outlet can be designed as a siphon. The water dispensing fitting can be sensor-controlled. Furthermore, a wastewater lifting station can be arranged within the housing to pump wastewater to a wastewater connection. Preferably, exactly one washbasin is designed as the hygiene facility. Alternatively, the hygiene facility can also include several washbasins.Additional equipment may be assigned to the hygiene facility, so that further equipment is arranged in the usable room.

[0014] For example, a soap dispenser, a cream dispenser, a disinfectant dispenser, a towel dispenser, a mirror, and / or lighting can be installed. The lighting can be linked to the open / closed status of the container door, for example, via a push button, or it can include a motion detector. This eliminates the need to press a switch to turn on the lighting in the insulated container.

[0015] For example, a water meter connection bracket with I can also be included as equipment. <altwasserzähler, ein Druckminderer oder eine Elektroverteilung ausgebildet sein. Weitere Ausstattungsbeispiele sind ein Abfallbehälter wahlweise mit oder ohne Deckel als Sammelstelle für beispielsweise benutzte Papierhandtücher.

[0016] Preferably, a high-pressure cleaner is installed in the hygiene station.

[0017] The frost protection device is designed to prevent the temperature inside the usable space from dropping below zero degrees Celsius.

[0018] The advantage of the proposed solution lies in the fact that the hygiene station, in a compact form, fulfills a wide range of construction site-specific needs. Its excellent usability at sub-zero temperatures is particularly noteworthy. The combination of the well-insulated tank and the frost protection system is a simple yet highly effective method of protecting the usable space from freezing. This allows all frost-sensitive elements, especially water pipes, to be safely located within the usable space. The hygiene station is therefore particularly well-suited for use on construction sites, especially small ones. It is not intended as a toilet, but rather as a hygiene station for cleaning purposes, thus providing a cleaning facility on the construction site.In particular, the hygiene station, due to its frost protection device and insulated tank, is also suitable for use in water supply and distribution. All elements requiring frost protection can be advantageously arranged within the protected tank.

[0019] According to an advantageous embodiment of the invention, the portable hygiene station does not have any sanitary facilities that primarily serve to receive or convey bodily excretions, in particular stool and / or urine.

[0020] In other words, the space contains neither a toilet nor a urinal or anything similar. The hygiene station is therefore not a toilet cubicle, but rather a hygiene station equipped internally only with hygiene facilities for personal care and / or cleaning.

[0021] An advantageous embodiment of the invention provides that the hygiene device can be used from the outside with the container door open, without entering the container. The hygiene device, or the washbasin, is thus arranged and designed within reach of a user standing outside the hygiene device.

[0022] According to an advantageous embodiment of the invention, the insulated housing of the portable hygiene station has a maximum width of 100 cm, a maximum depth of 150 cm and a maximum height of 220 cm.

[0023] Preferably, the width is in the range of 60 cm to 100 cm, the depth in the range of 90 cm to 120 cm, and the height in the range of 180 cm to 220 cm. Particularly preferred are a width of approximately 80 cm, a depth of approximately 120 cm, and a height of approximately 195 cm. The usable space then preferably has a width in the range of 50 cm to 70 cm, a depth in the range of 90 cm to 110 cm, and a height in the range of 150 cm to 170 cm. Particularly preferred is the width of the usable space of approximately 60 cm, a depth of approximately 100 cm, and a height of approximately 160 cm. These dimensions allow for both excellent transportability and mobility, as well as good thermal insulation of the walls of the insulated container.

[0024] The dimensions mentioned above also allow the hygiene facilities, especially the sink, to be used without having to enter the container. This eliminates floor cleaning costs, resulting in an economic advantage.

[0025] An advantageous further development of the invention provides that the frost protection device has a heating unit for heating the usable space of the insulated housing and a frost protection control, wherein the frost protection control is configured to switch on the heating unit when a predetermined minimum temperature is undershot.

[0026] The heating unit is generally suitable for supplying heat energy to the usable space. Specifically, it is an electric heater, preferably a fan heater or radiant heater. The frost protection control can include a thermostat with a temperature sensor. Setting the minimum temperature above zero degrees Celsius reliably prevents pipes in the usable space from freezing.

[0027] An advantageous further development provides, either alternatively or cumulatively, that the frost protection device is designed as a non-electric frost protection device. The frost protection device can then be integrated into a water supply system located downstream of the water supply connection. This frost protection device then includes a frost protection controller with a temperature sensor and a valve, and is designed to open the valve when a minimum temperature is undershot, allowing water to flow through the water supply system. This prevents the part through which the water flows from freezing.

[0028] In a further advantageous embodiment of the invention, the portable hygiene station has a water inlet hose which is connected and / or connectable to the water supply connection, wherein the water inlet hose is designed to be heated.

[0029] For example, the water inlet hose has a heating cable or similar component. This protects the water inlet hose, which is located outside the hygiene station, from freezing. Overall, this results in I <ombination mit dem gedämmten Behälter und der Frostschutzeinrichtung ein besonders zuverlässiges System.

[0030] An advantageous further development of the invention provides that a water heating device is arranged in the usable space for heating at least part of the water flowing to the water outlet.

[0031] In particular, the water heating device is located between the water supply connection and the water outlet of the washbasin. The water heating device is preferably an instantaneous water heater or a boiler. If the boiler is not fully insulated, it would also be conceivable to use the boiler as a heating unit to heat the room. Thus, the heating unit could also be designed as a boiler.

[0032] The water heating system makes it easy to provide hot water on the construction site. This allows for easier and more pleasant removal of stubborn dirt. It also enables hand cleaning with warm water.

[0033] According to the invention, a plurality of external water drainage connections are provided on the outside of the insulated housing, wherein a water distribution device for dividing water supplied by means of the water supply connection to at least the plurality of external water drainage connections and the water outlet of the washbasin is located in the usable space.

[0034] The numerous external water drainage connections are designed for the supply of fresh water on the construction site. In addition to providing a cleaning station, the hygiene station is thus also equipped to supply a comprehensive water supply on a construction site.

[0035] The water distribution system is therefore designed to distribute supplied water to multiple water connections. Since the water distribution system is located within the usable space, it can be reliably protected from frost by means of the insulated tank and the frost protection device. Especially in I <ombination mit dem beheizbaren Wasserzulaufschlauch ergibt sich ein frostschutzsicheres System. Durch die derartige Anordnung kann mittels der außenseitig angeordneten Wasserabfuhranschlüsse immer zuverlässig eine Wasserversorgung auf der Baustelle bereitgestellt werden, ohne aufwendige Systeme verwenden zu müssen.

[0036] The water heating device can preferably also be designed to heat at least a portion of the water flowing to the external connections, i.e., the external water outlets. This allows cold water in the room to be heated by the water heating device and then piped back outside so that warm water can be drawn from the hygiene station at a tap, i.e., the external connections. The water heating device is then, for example, located between the water supply connection and the water distribution system. The water heating device can, for example, be an instantaneous water heater. An instantaneous water heater with an operating voltage of 400V, a 32A fuse rating, and a power output of 21 kW is particularly suitable.

[0037] According to a particularly preferred variant of this embodiment, the hygiene station has an irrigation control system by means of which an automatic water supply can be set at at least one of the external water discharge connections.

[0038] This allows for automatic irrigation on construction sites. In particular, it would be possible to automatically water a concrete slab, such as a concrete floor slab. Often, concrete floor slabs are covered on construction sites to reduce evaporation and thus prevent the need for frequent watering. However, this carries the risk of insufficient watering, which can cause cracks in the concrete slab. On the other hand, continuous watering of the concrete slab leads to very high water consumption, and assigning a worker to watering results in high costs.

[0039] The irrigation controller enables optimal results with low water consumption and no manual effort. For example, the controller can be set to irrigate the base slab for approximately 15 minutes every hour, with irrigation continuing for 6 hours.

[0040] According to an advantageous embodiment of the invention, the portable hygiene station has at least one high-pressure cleaner which is arranged within the usable space.

[0041] The pressure washer and its lines are also protected by the insulated tank. An additional pressure washer can be provided as an option. This can also be mounted externally on the insulated tank.

[0042] In an advantageous embodiment of the invention, the insulated housing is designed as a double shell with an outer shell and an inner shell, wherein an insulating core is arranged between the outer shell and the inner shell. Preferably, the outer shell and / or the inner shell are formed in one piece. Particularly preferably, both shells are formed in one piece.

[0043] The term "bowl" here refers to a continuous, bowl-shaped structure. <tur verstanden. Die jeweiligen Schalen bildet hierbei mehrere, vorzugsweise alle, raumbegrenzenden Elemente des Gehäuses jeweils einstückig zusammenhängend aus. Als raumbegrenzende Elemente werden der Boden, die Decke, die Rückwand und die beiden Seitenwände verstanden, und zwar aus einer Ansicht von vorne bei geöffnetem Gehäuse.

[0044] The individual space-defining elements do not consist of individual panels that are then connected to other space-defining elements. Rather, the individual space-defining elements are formed with other space-defining elements in a continuous surface.

[0045] The outer shell is preferably designed to be impact and shock resistant. For example, the outer shell is made of polyethylene. The inner shell is made of an I <unststoff, insbesondere aus einem glasfaserverstärkten I<unststoff ausgebildet. Besonders bevorzugt sind die Außenschale und / oder die Innenschale als schalenförmig Formteile, insbesondere Spritzgußteile ausgebildet. Der Dämmkern ist vorzugsweise aus einem Polyurethan-Hartschaum ausgebildet. Der Dämmkern ist derart in den Zwischenraum zwischen Außenschale und Innenschale eingespritzt, dass der Dämmkern den Zwischenraum fest und fugenlos abschließt. Somit ist auch der Dämmkern zusammenhängend entlang mehrerer raumbegrenzenden Elemente ausgebildet.

[0046] The double-shell structure with an insulating core in between allows for particularly good thermal insulation of the insulated container. The materials mentioned above further enhance this effect.

[0047] According to an advantageous embodiment of the invention, the container door is formed from an inner plate and an outer plate, wherein an insulating core is preferably arranged between the inner plate and the outer plate.

[0048] For example, the inner and outer panels are each made of polyethylene. The insulating core can also be made of rigid polyurethane foam. This further improves the thermal insulation of the insulated container.

[0049] An advantageous further development of the invention provides that the insulated container or the container door has a seal that is at least substantially circumferential, by means of which the container door effectively seals the usable space when closed.

[0050] The seal preferably forms a complete circumferential seal. Particularly preferably, the seal completely surrounds the opening that can be closed by means of the container door. This further improves the thermal insulation of the insulated container.

[0051] Alternatively, a recess can be formed in the lower section of the seal. This creates a leakage opening from the usable space to the outside. In the event of a leak, this allows water to escape, preventing the usable space from filling completely with water. For example, the entire lower section of the seal can be recessed. In this case, when closed, the seal would only extend along the top and sides of the container door.

[0052] In a further advantageous embodiment of the invention, the insulated container has a plurality of externally arranged metal profiles and lifting elements arranged on the top and / or bottom.

[0053] On the one hand, the metal profiles on the outside of the insulated container ensure high stability. On the other hand, these metal profiles can improve the container's craneability by stiffening it. The lifting elements can, for example, consist of lifting eyes, preferably located on the top of the insulated container, for crane lifting. Alternatively or additionally, they can be lifting rails formed on the underside of the insulated container. These lifting rails allow for guided and safe lifting using a material handling equipment, such as a forklift.

[0054] A cleaning device for shoes / boots can be mounted on the outside of the insulated container. This device is supplied primarily with water from inside the container. The control unit for the cleaning device can therefore also be located in a frost-free area.

[0055] Furthermore, signs can be used for advertising purposes or I <ennzeichnung auf der Behälteroberfläche angebracht sein. Beispielsweise sind die Schilder aus Aluverbundplatten, welche an den Seitenflächen mit einer beispielhaften Größe von b=60cm und h=40cm angebracht sind. Somit kann die Hygieneeinrichtung mit einem Firmenschild versehen werden.

[0056] Furthermore, the tank may also have a wastewater connection for the discharge / transfer of wastewater. In particular, the tank has the wastewater connection at the rear or side. The wastewater can be discharged into the local sewer system via a gravity drain, a hose, or via the integrated wastewater pumping station with a pressurized line. <analnetz abgeleitet werden.

[0057] Further advantages of the invention will become apparent from the description and the drawings.

[0058] The invention is explained in more detail below with reference to a specific embodiment and the accompanying drawing. Further advantageous embodiments and combinations of features of the invention will become apparent from the following description and the entirety of the claims. Identical or equivalently functioning parts are designated with the same reference numerals. Brief description of the drawings

[0059] The drawings used to illustrate the exemplary embodiment show: Fig. 1 is a schematic perspective view of the portable hygiene station according to an embodiment of the present invention, and Fig. 2 is a schematic top view of the portable hygiene station according to an embodiment of the present invention.

[0060] Basically, identical parts in the figures are marked with the same reference symbols. Ways to implement the invention

[0061] The Fig. 1 shows a portable hygiene station 100 according to an embodiment of the present invention.

[0062] Hygiene station 100 has an insulated container 120. The container 120 consists of an insulated housing 121 and a container door 122. A usable space N is defined within the container 120, which can be selectively accessed and closed by means of the container door 122. The container door 122 is located in the Fig. 1 Only a trailing edge is shown. The rest of the container door 122 is obscured by the right side of the insulated container 120.

[0063] The insulated container 120 further features, as shown in Fig. 1 A circumferential seal 123 can be seen, by means of which the container door 122 and the insulated housing 121 effectively seal the usable space N when closed. The seal 123 completely surrounds an opening for access to the usable space N, which can be closed by means of the container door 122. Here, the seal 123 is attached to the insulated housing 121. Alternatively, it would also be conceivable to attach the seal 123 to the container door 122.

[0064] The insulated container 120 is fitted with a multitude of metal profiles 124, which stabilize the insulated container 120. Furthermore, exemplary lifting elements 125a and 125b are shown on the insulated container 120, which improve the mobility of the hygiene station 100. The lifting elements 125a arranged on the top of the insulated container 120 are eyelets that can be gripped using a crane hook. The lifting elements 125b formed on the underside of the insulated container 120 are lifting rails that simplify transport using a forklift or pallet jack. Although in the Fig. 1 Since both types of lifting elements 125a and 125b are shown, optionally only the lifting elements 125a, only the lifting elements 125b, both types of lifting elements 125a, 125b or neither of the lifting elements 125a, 125b can be formed.

[0065] The insulated container 120 has a width w, a height h and a depth d. Preferably, the width w is a maximum of 100 cm, the depth d a maximum of 150 cm and the height h a maximum of 220 cm.

[0066] Inside, i.e., in the usable space N, of the insulated container 120, a hygiene unit 110 is arranged. The hygiene unit 110 has a washbasin 111 with a water outlet 111a and a water drain 111b. The hygiene unit 110 includes a variety of equipment 114. Examples are shown in Fig. 1 A soap dispenser, a cream dispenser, a towel dispenser, and a light were arranged. Although this was not in the Fig. 1 As can be seen, a mirror may preferably be arranged on the container door 122. Furthermore, a water heating device is preferably arranged in the usable space N, which is described in more detail in connection with Fig. 2 is described.

[0067] As in Fig. 1As can be seen, the washbasin is arranged within container 120 in such a way that a user can use the hygiene facility 110 without entering container 120. Entering typical sanitary containers available on the market results in significant soiling from dirty shoes, which incurs additional costs for cleaning the floor surfaces.

[0068] As in Fig. 1 It can also be seen that a frost protection device 140 is arranged in the usable space N, which is designed to prevent the temperature inside the usable space N from falling below zero degrees Celsius.

[0069] An external water supply connection 130 is provided on one side of the insulated container 120. A water inlet hose 131 is connected to the external water supply connection 130. The water inlet hose 131 is preferably designed to be heated. In particular, the water inlet hose 131 can have a heating cable, a heating layer, a heating wire, or the like. This ensures the water supply to the portable hygiene station 100. Furthermore, a plurality of external water outlet connections 135 are located on the outside of the insulated container 120. These allow hoses and / or devices to be supplied with water. A water sprayer on the hose or a high-pressure cleaner 136 is also provided on the outside as an additional high-pressure cleaner 136, either in addition to or as an alternative to a high-pressure cleaner 113 in the usable space N. The high-pressure cleaner 113 is only in the Fig. 2 to recognize.

[0070] The Fig. 2 This is a schematic top view of the portable hygiene station 100 according to the present invention. The schematic Fig. 2 This shows details that are in the Fig. 1 are not recognizable. This could be the case with the one in the Fig. 2 hygiene station 100 shown around the one in the Fig. 1 Hygiene station 100 shown. Aspects already related to Fig. 1 These points, which have already been described, will not be discussed in detail here. However, they generally refer to the Fig. 2 transferable.

[0071] A first in the Fig. 2The detail to be observed relates to the insulated container 120 and its insulated housing 121. The insulated housing 121 is designed as a double shell. In particular, the insulated housing 121 has an outer shell 121a and an inner shell 121c. An insulating core 121b is formed between the outer shell 121a and the inner shell 121c. The outer shell 121a is preferably made of polyethylene. The inner shell 121c is preferably also made of polyethylene or of a glass fiber reinforced <unststoff ausgebildet. Der Dämmkern 121b ist vorzugsweise aus einem Polyurethan-Hartschaum ausgebildet. Diese Struktur schafft gemeinsam mit der Frostschutzeinrichtung 140 einen einfachen und effizienten Schutz der in dem Nutzraum N angeordneten Elemente.

[0072] As in the Fig. 2As indicated, the frost protection device 140 comprises a heating unit 141 and a frost protection control unit 142. The heating unit 141 is designed to heat the usable space by supplying thermal energy when the frost protection control unit 142 detects that a predetermined minimum temperature has been undershot.

[0073] Another one in the Fig. 2 The detail to be observed concerns the water distribution of the portable hygiene station 100. The portable hygiene station 100 has a water distribution unit 150. This water distribution unit 150, for example, has one internal water supply connection 151 and four internal water outlet connections 152. The water distribution unit 150 is thus designed to distribute the supplied water to four connections. Alternatively, depending on the application, a different number of water outlet connections 152 would also be conceivable.

[0074] The water distribution device 150, or rather its internal water supply connection 151, is connected to the water supply connection 130 located on the outside of the insulated housing 121. Water can thus be supplied from the water inlet hose 131 to the water distribution device 150 via the external water supply connection 130. The water inlet hose 131 and the frost protection device 140, together with the insulated tank 120, reliably prevent the associated pipes and the water distribution device 150 from freezing.

[0075] The water distribution device 150, or rather three of its internal water drainage connections 152, are connected to the three water drainage connections 135 located on the outside of the insulated housing 121. This ensures a reliable, frost-proof water supply at the construction site at all times.

[0076] Another of the internal water drain connections 152 is connected via a water heating device 112 to the water inlet 111a of the washbasin 111. This allows the washbasin 111 to also be supplied with water. Via the I <opplung mit der Wasserheizeinrichtung 112 kann das Wasser zudem erwärmt werden.

[0077] In the Fig. 2 It is indicated that the high-pressure cleaner 130 can also be designed to be connected to the water distribution device 150.

[0078] Overall, the described portable hygiene station 100 compactly fulfills a wide range of construction site-specific needs. Thanks to a variety of features, the hygiene station is also ideally suited for use in low temperatures.

[0079] It should be noted that the features of the invention described with reference to individual embodiments or variants, such as the type and design of the individual I
