Description

technical field

The invention relates to a portable hygiene station for construction sites, in particular for small construction sites.

State of the art

It is known to set up toilet cubicles as hygiene stations on construction sites. Such hygiene stations typically have a simple cabin with a cabin door, by means of which an interior of the cabin can be selectively opened and closed. A toilet and, in better-equipped cabins, a washbasin with a water tank are often designed as hygiene facilities.

Such a hygiene station is, for example, from DE 20 2016 101 186 U1 known. The one in the DE 20 2016 101 186 U1 The hygiene station described has a booth with a floor part, a ceiling part, corner posts which extend between the floor part and the ceiling part and side walls which are 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 hygiene station has a sanitary unit designed as a toilet with a water tank. The water tank is designed so that it can be hung on an end section of one of the corner posts by means of a holder.

Although the hygiene stations known from the prior art can be used uncomplicatedly and quickly on construction sites with their simple structure, the known hygiene stations are not adequately adapted to the conditions and needs on construction sites, in particular small construction sites. It would therefore be desirable to further develop the known hygiene stations to the effect that they are better suited for use on construction sites.

Presentation of the invention

The invention is therefore based on the object of specifying a hygiene station that eliminates the above-mentioned problems and disadvantages of the prior art. In particular, it is the object of the present invention to specify a hygiene station that is well suited for use on construction sites, in particular small construction sites.

This object is solved by the subject matter of independent claim 1. Further possible developments of the invention are specified in particular in the dependent claims.

The solution according to the invention consists in particular in specifying a portable hygiene station for construction sites, in particular small construction sites, which has at least one hygiene device and an insulated container in which the at least one hygiene device is arranged, the insulated container having the following: an insulated housing, which in its interior defines a usable space in which the at least one hygiene device is accommodated; and a container door which is hinged to the insulated housing and by means of which the usable space of the insulated container can be selectively opened and closed, with an external water supply connection being formed on the insulated housing, with the hygiene facility having at least one washbasin with a water outlet and a water outlet has, wherein the portable hygiene station has a frost protection device, which is arranged in the usable space of the insulated housing.

The hygiene station is characterized in that it is designed to be portable or transportable, that is to say easily transportable. The hygiene station is therefore not tied to a fixed location, but can be used at changing locations.

A small construction site is understood to mean a construction site of the size required for a single-family house. Here, the hygiene requirements are the same as for larger construction sites, depending on the maximum number of employees. The sanitary containers available on the market are usually equipped with a large number of washing areas, which are not required on small construction sites. Therefore, they cannot be used economically.

A thermally insulated container is understood to be an insulated container. In particular, this is a container that is designed with thermal insulation that reduces the passage of thermal energy in order to protect the useful space from cooling down too much. This can be done, for example, by an appropriate covering that is arranged in a wall of the insulated container.

The housing of the insulated container can be closed using the container door. The joint used here is preferably a swivel joint, so that the container door is pivotably attached to the insulated housing. The insulated container separates the usable space from an external environment. It is on an outside, so on a dem The side facing away from the usable space, the insulated container attached to the outside water supply connection. The water supply connection is used to supply water to the hygiene facility. For this purpose, a water supply hose can be connected to the water supply connection.

The hygiene facility is at least the wash basin, which is designed in particular as a hand wash basin. The washbasin is designed as a container that is concave towards the top. The water outlet can be designed as a fitting for metered dispensing of warm and/or cold water. The water outlet can be designed as a siphon. The fitting for dispensing the water can be sensor-controlled. Furthermore, a waste water lifting system can be arranged within the housing in order to lift waste water or waste water to a waste water connection. Precisely one washbasin is preferably designed as a hygiene facility. Further items of equipment can be assigned to the hygiene facility, so that further items of equipment are arranged in the usable space.

For example, a soap dispenser, a cream dispenser, a disinfectant dispenser, a towel dispenser, a mirror and/or lighting can be arranged. The lighting can be linked to the opening status of the container door, for example by means of a push button, or can include a motion detector. This means that no switch needs to be pressed to switch on the lighting in the insulated container.

For example, a water meter connection bracket with a cold water meter, a pressure reducer or an electrical distributor can also be designed as equipment. Other examples of equipment include a waste bin with or without a lid as a collection point for used paper towels, for example.

A high-pressure cleaner is preferably arranged in the hygiene device.

The frost protection device is designed to prevent the temperature inside the usable space from falling below zero degrees Celsius.

The advantage of the proposed solution is that the hygiene station fulfills a large number of construction site-specific needs in a compact manner. Particularly noteworthy is the good usability of the hygiene station at low temperatures below zero degrees Celsius. The combination of the well-insulated container and the frost protection device is a simple and at the same time extremely effective method of protecting the usable space from frost. In this way, all elements that are susceptible to frost, in particular the water pipes, can be arranged in a protected manner within the usable space. The hygiene station is therefore particularly well suited for use on construction sites, especially small construction sites.

According to an advantageous development 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.

Preferably, the width is in a range from 60 cm to 100 cm, the depth is in a range from 90 cm to 120 cm and the height is in a range from 180 cm to 220 cm. The width is particularly preferably about 80 cm, the depth about 120 cm and the height about 195 cm. The usable space then preferably has a width in a range of 50 cm to 70 cm, a depth in a range of 90 cm and 110 cm and a height in a range of 150 cm and 170 cm. The width of the usable space is particularly preferably about 60 cm, the depth is about 100 cm and the height is about 160 cm. With these dimensions, on the one hand particularly good transportability and mobility and on the other hand good thermal insulation of the walls of the insulated container are possible.

The dimensions mentioned above also allow the hygiene facility, in particular the washbasin, to be used without having to step on the container. This eliminates cleaning costs for the floor, resulting in an economic advantage.

An advantageous development of the invention provides that the frost protection device has a heating unit for heating the usable space of the insulated housing and an frost protection controller, the frost protection controller being designed to turn on the heating unit when the temperature falls below a predetermined minimum.

The heating unit is generally suitable for supplying thermal energy to the usable space. In particular, it is an electric heater, preferably a fan heater or radiant heater. The freeze protection control can have a thermostat with a temperature sensor. If the minimum temperature is specified as a temperature above zero degrees Celsius, it can be reliably prevented that lines in the usable space freeze.

Alternatively, an advantageous development provides that the antifreeze device is designed as a currentless antifreeze device. The anti-freeze device can then be placed in a behind the what water supply connection trained water supply system to be integrated. The antifreeze device then has an antifreeze controller with a temperature sensor and a valve and is designed to open the valve when the temperature falls below a minimum level in such a way that water flows through the water supply system. As a result, the part through which flow occurs can be prevented from freezing.

In a further advantageous development of the invention, the portable hygiene station has a water supply hose which is connected and/or can be connected to the water supply connection, the water supply hose being heatable.

For example, the water supply hose has a heating band or the like. In this way, the water inlet hose arranged outside the hygiene station can also be protected from frost. Overall, in combination with the insulated container and the frost protection device, this results in a particularly reliable system.

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

In particular, the water heating device is arranged between the water supply connection and the water outlet of the washbasin. The water heating device is preferably a flow heater or a boiler. If the boiler is not completely insulated, it would also be conceivable to use the boiler as a heating unit to heat the usable space. Thus, the heating unit could also be designed as a boiler.

Using the water heating device, it is possible to easily provide hot water at the construction site. This makes it easier and more convenient to remove stubborn dirt. There is also the possibility of hand cleaning with warm water.

In an advantageous development of the invention, a large number of external water discharge connections are formed on the outside of the insulated housing, with a water distribution device for dividing water supplied by means of the water supply connection to at least the large number of external water discharge connections and the water outlet of the washbasin in the usable space.

The water distribution device is therefore designed to distribute supplied water to a number of water connections. Since the water distribution device is arranged within the usable space, it can be reliably protected from frost by means of the insulated container and the antifreeze device. A frost-proof system results, especially in combination with the heatable water inlet hose. With such an arrangement, a water supply can always be reliably provided on the construction site by means of the water discharge connections arranged on the outside, without having to use complex systems.

The water heating device can preferably also be designed at the same time to heat at least part of the water flowing to the external connections. In this way, cold water in the work space can be heated by means of the water heating device and fed back outside in order to also be able to draw warm water from the hygiene station at a tapping point, i.e. the external connections. The water heating device is then arranged, for example, between the water supply connection and the water distribution device. The water heating device can be, for example, a flow heater. A flow heater with an operating voltage of 400V, a fuse of 32A and an output of 21 kW is particularly suitable.

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

This can be used for automatic watering on the construction site. In particular, it would be possible in this way to automatically water a concrete slab, for example a concrete floor slab. The concrete floor slab is often covered on construction sites to reduce evaporation and thus prevent it from having to be watered at too short intervals. However, there is a risk that this will lead to insufficient irrigation, which can cause cracks in the concrete slab. Permanent watering of the concrete slab, on the other hand, leads to very high water consumption and dedicating an employee to water it is very expensive.

By means of the irrigation control, an optimal result can be achieved with low water consumption and without personnel costs. The irrigation control can be set, for example, so that the base plate in a hour is watered for about ¼ hour and watering is carried out for 6 hours.

According to an advantageous development of the invention, the portable hygiene station has at least one high-pressure cleaner, which is arranged inside the usable space.

The high-pressure cleaner and its lines are also protected by the insulated container. Another high-pressure cleaner can optionally be provided. This can also be arranged on the outside of the insulated container.

In an advantageous development of the invention, the insulated housing is designed in two shells with an outer shell and an inner shell, with an insulating core being arranged between the outer shell and the inner shell.

A cohesive shell-shaped structure is understood as a shell.

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 a plastic, in particular a glass fiber reinforced plastic. The insulating core is preferably formed from a rigid polyurethane foam. The insulating core is injected into the space between the outer shell and the inner shell in such a way that the insulating core closes the space tightly and seamlessly.

Particularly good thermal insulation of the insulated container can be achieved with the structure of a double shell and an insulating core arranged in between. The above materials further enhance this effect.

According to an advantageous development of the invention, the container door is formed from an inner panel and an outer panel, with an insulating core preferably being arranged between the inner panel and the outer panel.

For example, the inner panel and the outer panel are each formed as polyethylene panels. The insulation core can also be rigid polyurethane foam. This further improves the thermal insulation of the insulated container.

An advantageous further development of the invention provides that the insulated container or the container door has an at least essentially circumferential seal, by means of which the container door effectively seals the usable space when it is closed.

The seal is preferably designed to be completely circumferential. The seal particularly preferably completely surrounds the opening that can be closed by means of the container door. This further improves the thermal insulation of the insulated container.

As an alternative to this, a recess can also be formed in a lower region of the seal. At this point, a leak is created from the usable space to the outside. This allows water to escape in the event of a leak, so that the usable space does not fill up completely with water. For example, the entire lower area of the seal can also be left out. Then the seal would only run at the top and sides of the container door when closed.

In a further advantageous development of the invention, the insulated container has a large number of metal profiles arranged on the outside and lifting elements arranged on the top and/or bottom.

On the one hand, the metal profiles on the outside of the insulated container ensure high stability. On the other hand, the metal profiles can improve the craneability of the insulated container by stiffening it. The lifting elements can, for example, be eyelets for crane lifting, which are preferably arranged on an upper side of the insulated container. Alternatively or additionally, these can be lifting rails that are formed on an underside of the insulated container. Guided and safe lifting by means of an industrial truck, for example a forklift, can be carried out on the lifting rails.

A cleaning device for cleaning shoes/boots can be arranged on the outside of the insulated container. This is fed in particular with water from inside the container. The regulation of the cleaning device can thus also be housed in a frost-free area.

Furthermore, signs for advertising purposes or identification can be attached to the container surface. For example, the signs are made of aluminum composite panels, which are attached to the side surfaces with an exemplary size of w=60cm and h=40cm. In this way, the hygiene facility can be provided with a company nameplate.

Furthermore, the container can also have a waste water connection for dispensing/transferring waste water. In particular, the container rear or the waste water connection on the side. The waste water can be discharged into the local sewage system using a gravity sewer pipe or a hose line or the built-in waste water lifting station with a pressurized line.

Ways to carry out the invention

the 1 12 shows a portable hygiene station 100 according to an embodiment of the present invention.

The hygiene station 100 has an insulated container 120 . The container 120 is made up of an insulated housing 121 and a container door 122 . A usable space N is defined within the container 120, which can be made accessible and closed as desired by means of the container door 122. From the container door 122 is in the 1 only one trailing edge shown. The remainder of the bin door 122 is concealed by the right side of the insulated bin 120 .

The insulated container 120 also has, as in 1 to recognize a peripheral seal 123, by means of which the container door 122 and the insulated housing 121 in the closed state effectively seal the usable space N. The seal 123 completely surrounds an opening, which can be closed by means of the container door 122, for access to the usable space N. Here the seal 123 is attached to the insulated housing 121 . As an alternative to this, it would also be conceivable to attach the seal 123 to the container door 122 .

A multiplicity of metal profiles 124 are formed on the insulated container 120 and 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. In this case, the lifting elements 125a arranged on the upper side of the insulated container 120 are eyelets which can be grasped by means of a crane hook. The elevating members 125b formed on a bottom of the insulated container 120 are elevating rails, which facilitate transportation by a forklift or an ant. Although in the 1 both types of lifting elements 125a and 125b are shown, only the lifting elements 125a, only the lifting elements 125b, both types of lifting elements 125a, 125b or none of the lifting elements 125a, 125b can be formed.

The insulated container 120 has a width w, a height h and a depth d. The width w is preferably at most 100 cm, the depth d is at most 150 cm and the height h is at most 220 cm.

A hygiene device 110 is arranged inside, ie the usable space N, of the insulated container 120 . The hygiene device 110 has a washbasin 111 with a water outlet 111a and a water outlet 111b. The hygiene facility 110 includes a large number of items of equipment 114 1 a soap dispenser, a cream dispenser, a towel dispenser, and lighting arranged. Although this is not in the 1 as can be seen, a mirror can preferably be arranged on the container door 122 . In the utility space N, a water heating device is also preferably arranged, which is more precisely in connection with 2 is described.

As in 1 As can be seen, the washbasin is arranged within the container 120 in such a way that it is possible for a user to use the hygiene device 110 without entering the container 120 . When entering the sanitary containers typically available on the market, soiled shoes cause heavy soiling, which entails additional costs for cleaning the floor surfaces.

As in 1 to recognize, an antifreeze device 140 is also arranged in the usable space N, which is designed to prevent that the temperature within the usable space N falls below zero degrees Celsius.

An outside water supply port 130 is formed on an outside of the insulated container 120 . A water supply hose 131 is connected to the outside water supply port 130 . The water inlet hose 131 is preferably designed to be heatable. In particular, the water supply hose 131 can have a heating tape, a heating layer, a heating wire or the like. In this way, the water supply to the portable hygiene station 100 can be ensured. Furthermore, there are a large number of external water discharge connections 135 on the outside of the insulated container 120. These enable hoses and/or devices to be supplied with water. A water sprayer on the hose or a high-pressure cleaner 136 as a further high-pressure cleaner 136 in addition to or as an alternative to a high-pressure cleaner 113 in the usable space N is also embodied on the outside. The high-pressure cleaner 113 is only in the 2 to recognize.

the 2 12 is a schematic plan view of the portable sanitation station 100 according to the present invention. The schematic 2 shows details in the 1 are not recognizable. It can be in the in the 2 shown hygiene station 100 in the 1 acting hygiene station 100 shown. On aspects already related to 1 have been described will not be discussed in detail. However, these are general to the 2 transferable.

A first in the 2 The detail to be recognized relates to the insulated container 120 or its insulated housing 121. The insulated housing 121 is of two-shell construction. 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 plastic. The insulating core 121b is preferably formed from a rigid polyurethane foam. This structure, together with the frost protection device 140, provides simple and efficient protection of the elements arranged in the useful space N.

Like in the 2 indicated, the antifreeze device 140 has a heating unit 141 and an antifreeze controller 142 . The heating unit 141 is designed to heat the usable space by supplying thermal energy when the frost protection controller 142 determines that the temperature has fallen below a predetermined minimum.

Another in the 2 The detail to be recognized relates to the water distribution of the portable hygiene station 100. The portable hygiene station 100 has a water distribution device 150. In this case, the water distribution device 150 has, for example, an inner water supply connection 151 and four inner water discharge connections 152 . The water distribution device 150 is thus designed to distribute the supplied water to four connections. As an alternative to this, a different number of water discharge connections 152 would also be conceivable, depending on the application.

The water distribution device 150 or the inner water supply connection 151 thereof is connected to the water supply connection 130 arranged on the outside of the insulated housing 121 . Thus, water can be supplied from the water supply hose 131 to the water distribution device 150 by means of the external water supply connection 130 . The water inlet hose 131 and the antifreeze device 140, together with the insulated container 120, reliably prevent the associated lines and the water distribution device 150 from freezing.

The water distribution device 150 or three of the inner water discharge connections 152 thereof are connected to the three water discharge connections 135 arranged on the outside of the insulated housing 121 . In this way, a frost-proof water supply can always be reliably provided on the construction site.

Another of the inner water discharge connections 152 is connected to the water inlet 111a of the washbasin 111 via a water heating device 112 . In this way, the washbasin 111 can also be supplied with water. The water can also be heated via the coupling to the water heating device 112 .

In the 2 indicates that the high-pressure cleaner 130 can also be designed to be connected to the water distribution device 150 .

Overall, the portable hygiene station 100 described fulfills a large number of construction site-specific needs in a compact manner. The hygiene station is also ideal for use at low temperatures thanks to a large number of measures.

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 components and their exact dimensions and spatial arrangement can also be present in other embodiments, unless otherwise stated or prohibited for technical reasons. In addition, of such features of individual embodiments described in combination, not all features necessarily have to be implemented in a relevant embodiment.
