Description

The invention relates primarily to a steam cabin having a steam room adapted to accommodate one or more persons, comprising an ultra-vapor system adapted to realize a visible vapor cloud in the vapor space.

The invention secondly relates to a refrigerated cabin having a refrigerated space adapted to accommodate one or more persons, comprising a refrigeration system.

The invention relates in the third place to a module configured to discharge cold water mist into a room.

A steam cabin is designed to accommodate one or more persons and has a steam room in which certain conditions can be created under the influence of the supply of steam. In general, these conditions are a temperature of the order of 40 ° C to 50 ° C and an atmospheric humidity of about 80% to 90% or even higher. This distinguishes a steam cabin from a sauna, where the temperature during use must be much higher and the humidity just lower.

A basic part of a steam cabin is a steam generator adapted to generate steam and having an outlet for venting the steam to the steam space. In addition, a steam cabin can be provided with other components, in particular components such as a shower, massage jig, etc. for the direct supply of water to the steam room.

It is a common misconception that steam is visible. This misunderstanding is based on perceptions of fog, that is, visible clouds that actually consist of (very) fine water droplets at a high temperature. Due to this misunderstanding, many users of steam cabins expect to see clouds in the steam cabin when it is in operation. However, this is not always the case, giving users of a steam cabin the wrong feeling that the steam cabin is not functioning optimally.

It is an object of the invention to provide a technique by which the expectation of being able to see clouds in a steam cabin can be fulfilled. To this end, the invention provides a steam cabin having a steam room adapted to accommodate one or more persons, comprising a steam generator adapted to generate steam and having an outlet for venting the steam to the steam room. and an ultradampfsystem configured to realize a visible cloud of vapor in the vapor space, wherein the ultradampfsystem comprises a mist device having an ultrasonic nebulizer configured to produce cold water mist, the mist device having an outlet for capturing the cold water mist at a vaporization point Leave position in the steam room in the steam room to let the cold water mist come into contact with the steam.

The invention is based on the recognition that steam can be made visible by bringing cold water mist into contact with it. As soon as cold water mist is introduced into the steam room and steam present in the steam room penetrates, a process takes place in which steam is removed from the heat, resulting in partial condensation of the steam. By causing the cooling of the steam with cold water mist, it is possible to let a volume of steam penetrate well with the cold at once, whereby a spectacular effect of a large visible cloud can be obtained.

In order to produce the cold water mist, an ultrasonic atomizer is used according to the invention. An ultrasonic nebulizer is a compact device that can be easily installed. For a correct function of such a nebulizer, it is actually only necessary to have a power connection and a tap water supply. The tap water may eventually be cooled at a position upstream of the ultrasonic nebulizer. Within the scope of the invention, it has been found that good results can be obtained with generally available ultrasonic nebulizers, whereby large visible clouds of vapor can be realized in a very effective manner.

Within the scope of the invention, it is possible to provide a control which allows a user to create a visible steam effect at a time which he desires. The mist device may for this purpose have an inlet for introducing optionally cooled tap water into the mist device, wherein a control of the water supply to the mist device is provided, which is intended to supply a limited amount of tap water to the mist device upon activation of the Ultradampfsystems. Here, the ultradampfsystem may include a radiator configured and arranged to cool the tap water upstream of the inlet of the mist device.

For example, it may be convenient to have a button shorted by a user can be pressed to activate the fog device. In practice, it is most convenient for a user if the steam effect can be temporarily generated as desired and needed. In general, it is convenient if the cold water mist is supplied in a limited amount to the vapor space. A supply of a small amount of cold water mist immediately creates a great effect as soon as it enters a steam-filled steam room. In practice it can be easily tuned, which is a suitable amount for a steam room of a certain size. Too much cold water mist does not produce any additional effect when it comes to providing a visible vapor effect, and moreover has a cooling effect, which in most cases may not be desirable.

Preferably, the cold water mist at a higher level than the steam is supplied to the vapor space. In fact, in this way, a good penetration of the cold water mist in the steam can be effected, which is due to the fact that cold provides for a downward flow and heat for an upward flow. In particular, the outlet of the mist device with respect to the vapor space may be at a higher level than the outlet of the steam generator.

It may be convenient if the cold water mist is forced to blow into the steam room to supply the cold water mist to the steam room. For example, a fan can be used to realize an effective flow of the cold water mist; In particular, the ultradampfsystem may include a fan arranged and arranged to force the cold water mist into the vapor space for supplying the cold water mist into the vapor space.

In terms of safety, in terms of user health, it is beneficial for the Ultradampfsystem to include a Legionella protection system that is set up and arranged to subject the water mist to Legionella protection treatment before it is discharged to the steam room. For example, such a legionella protection system may comprise a lamp for emitting ultraviolet radiation, which type of ultraviolet radiation may be UV-B. It is also possible to subject the water used to generate the water mist to a legionella protection treatment, for example, by flowing it through a legionella protection filter.

The invention further provides a refrigerated cabin having a refrigerated space adapted to accommodate one or more persons, comprising a refrigeration system having a mist device having an ultrasonic nebulizer arranged to produce cold water mist and an outlet has to omit the cold water mist to the cooling room. According to a finding on which the invention is based, the use of cold water mist to realize cooling in a cooling booth offers advantages over conventional cooling techniques, in particular because the ratio between the cooling effect obtained and the energy required is relatively favorable. Incidentally, by cooling cabin is meant a cabin in which at least one person can sit, and which can be applied, for example, to a high-temperature device such as a sauna or a steam bath. The various options described above with respect to the steam cabin can be applied to the cooling cabin in a similar manner.

It may be practical if the steam cabin or chilling cabin comprises a module installed in a wall of the cabin housing the misting device and provided with a grid configured to expel cold water mist generated by the misting device Leave module. By working with such a module, it is possible to easily apply the invention to existing cabins and / or to integrate them into their design. The invention therefore further provides a module configured to generate cold water mist and to discharge the cold water mist into a room, comprising a mist housing in which a mist space is located, an ultrasonic nebulizer disposed in the mist space, a water inlet, which gives access to the fog room from outside the fog housing, and a grid located in a wall of the fog housing. For example, as noted above, it is possible for the module to include a fan located in the mist space and / or including a lamp located in the mist space and configured to emit ultraviolet radiation.

In the context of the invention, an arrangement of said module and a mounting box can be provided, which encloses the module largely. The mounting box is then a tool to mount the module, for example in the wall of a steam cabin. It can be seen from the above that the design of the mounting box must always be directed to allow connection of the module to water and electricity at suitable locations and also to allow the outlet of the cold water mist from the module.

The figures relate to a module 100 according to the invention, which is adapted to be used in a steam cabin and for which other applications are conceivable, as will be explained later in this description. Since steam cabins are known per se, no further explanation is offered in this text. For the sake of completeness, however, it is expressly pointed out that a steam cabin has a steam space and is provided with a steam generator, wherein the steam generator is arranged to generate steam and has an outlet to discharge the steam to the steam space. For residential applications, the dimensions of the steam room may be adapted to a limited number of people, for example one or two, while for professional applications the dimensions may be significantly larger.

module 100 is configured to generate and dispense cold water mist and will therefore hereinafter be referred to as a fog module 100 designated. An important component of the fog module 100 is an ultrasonic nebulizer 10 , The ultrasonic nebulizer 10 is capable of producing a fine mist of water based on a supply of water. In the example shown is the Ultraschallvernebeler 10 with a series of buttons 11 provided to drain the water mist. The number of keys 11 is at least one and can be freely selected within the scope of the invention. Further, the ultrasonic nebulizer 10 with a steam connection point 12 and a fuse 13 which is part of a regulation to the nebulizer 10 Turn off when it detects that the nebulizer 10 is underwater to an insufficient degree. Said regulation, which is known per se, is in a Ultraschallvernebeler 10 important to ensure proper functioning of this type nebulizer.

In the fog module shown 100 is the ultrasonic nebulizer 10 in the inner space of a housing 20 arranged, the housing 20 subsequently as a mist housing 20 referred to and the inner space is hereinafter referred to as fog room. In the following description, the use of terms such as below and above will refer to a normal, operative orientation of the fog module 100 assumed, that is, an orientation as shown in the various figures, wherein a bottom wall 21 with the ultrasonic atomizer on it 10 on a bottom of the fog module 100 located in which adjoining towering walls 22 . 23 . 24 the fog module 100 of which three are shown in the figures for clarity, extend substantially in the vertical direction, and one in which a top wall 25 at a top of the fog module 100 located. One of the towering walls 22 . 23 . 24 is a composite wall with a grid 26 , which serves to let out the cold water mist from the fog room. This towering wall is subsequently called the front wall 22 referred to, while the opposite towering wall as the back wall 24 referred to as. A lower part of the housing 20 is considered a waterproof container, which is suitable to take a lot of water, which is necessary to the ultrasonic nebulizer 10 work well, record.

In the back wall 24 there is an air inlet opening 27 , A fan 30 is at the height of the air inlet opening 27 in the fog box 20 arranged and serves to during the operation of the fog module 100 through the ultrasonic nebulizer 10 generated cold water mist over the grid 26 the front wall 22 from the mist housing 20 to blow. During operation is the fog module 100 in dispensing cold water mist effectively, because the ultrasonic nebulizer 10 at a position directly behind the grid 26 and no hoses, lines or the like must be used to discharge the cold water mist in a desired area.

The back wall 24 is at the back with a holder 35 provided for serving (not shown) components of the electronic control of the fog module 100 take. The electronic control of the fog module 100 acts among other things with a water level sensor 36 to the water level in the mist housing 20 maintain, and a temperature sensor 37 to the temperature of the water in the mist housing 20 uphold, together. The water supply and drainage from the mist housing 20 be based on data regarding the water level and the Temperature regulated. For the aforementioned water supply and water drainage is the back wall 24 at the back with connecting parts 38 and at the front with an opening 39 provided that the exchange of water between the inside and the outside of the mist housing 20 over the connecting parts 38 allows to which water pipes (not shown) can be connected.

Wherever water, especially water mist, is used, there is a risk of contaminating the water with Legionella bacteria. To exclude this risk, is the fog module 100 with a legionella protection system 40 Provided. In the example shown, this system includes 40 a lamp 41 for emitting ultraviolet radiation, for example UV-B ultraviolet radiation. The lamp 41 is at a strategic location in the fog module 100 positioned, namely at an elevated location in the fog module 100 , to the upper wall 25 so that it can be ensured that during operation of the fog module 100 the entire water mist is subjected to a legionella protection treatment. Not just the water mist, the fog module 100 leaves, it is guaranteed that this is free of Legionellenkontamination, even any (spray) water that is above the grid 26 the front wall 22 in the mist housing 20 comes directly under the influence of the lamp 41 , Convenient is when the fog module 100 provided with a regulation that ensures that the fog module 100 can not be put into operation if the legionella protection system 40 does not seem to work, which, for example, may be the case when the lamp 41 is defective.

For mounting the fog module 100 For example, in a wall of a steam cabin, it is convenient if for the fog module 100 a mounting box 101 , as in 9 shown is applied. This mounting box 101 may have a simple shape and consist for example of a series of stainless plates. In the example shown, the fog module has 100 a terminal block 45 that is below and behind the fog module 100 at some distance from the connecting parts 38 located. Practical is when the design of the mounting box 101 matched, on the back of this terminal block 45 reachable, and at the front of the grid 26 the front wall 22 to release. In 9 is illustrated as the fog module 100 in the mounting box 101 can be pushed. In an end position of the fog module 100 in the mounting box 101 lies the grid 26 the front wall 22 on a front edge 102 of the mounting box 101 on.

Attaching the fog module 100 For example, in the wall of a steam cabin can be done by first the mounting box 101 placed in the wall and then the fog module 100 is pushed in and the necessary connections are made. In this design, it's easy, the fog module 100 For example, for maintenance purposes or to replace this. The design of the steam cabin does not or hardly needs to be adapted, as it is actually sufficient if there is room to place the mounting box 101 is.

In reference to 10 subsequently becomes the function of the fog module 100 explained. It is assumed that the fog module 100 is connected to water and electricity, and also that the mist space is sufficiently filled with water to ensure proper functioning of the ultrasonic nebulizer 10 to enable. In 10 is the water level of the existing in the fog room water with the reference number 14 designated.

If the fog module 100 is activated, the Ultraschallvernebeler 10 put into operation to produce water mist, and the fan 30 is put into operation to blow the water mist out of the fog room. This water mist passes over the water level 14 , what in 10 is schematically indicated by a vertically oriented arrow, wherein the water mist itself is shown as an arrangement of curved lines. At the above point above the water level 14 is the water mist in the area of the lamp 41 of the legionella protection system 40 , Furthermore, the water mist at this point under the influence of the fan 30 , whereby an outgoing flow is obtained by the fog space through the grid 66 the front wall 22 is directed. This flow is in 10 shown schematically by a horizontal arrow in the left portion of the figure, while an air supply for generating the flow by means of a horizontal arrow, in the right area of the figure in the amount of the representation of the fan 30 is shown schematically.

Water supplied to the mist space may be tap water taken directly from the tap water system. However, a suitable cooler may also be used to lower the temperature of the tap water before it is admitted into the mist space. The temperature of the tap water may be, for example, in a range of 5 ° C to 8 ° C, while with a cooler, a temperature in a range of 1 ° C to 2 ° C can be realized. In any case, the temperature sensor has 37 during operation of the fog module 100 a function to prevent the temperature of the water from reaching a value above a certain maximum value, otherwise under the influence of the function of the ultrasonic nebulizer 10 could take place because it releases heat. A maximum temperature may be, for example, 10 ° C. If it turns out that the temperature of the water in the fog room is too high, this causes a supply of water to the fog room and possibly also a discharge of water. The water supply and drainage are in 10 by means of two horizontal arrows, in the right area of the figure at the level of the representation of Ultraschallvernebelers 10 can be seen, shown schematically. The water supply and drainage are also using the water level sensor 36 regulated. If the water in the fog room is lower than a certain minimum, this causes a water supply into the fog room. It should be clear to a person skilled in the art that a control circuit can be provided by means known per se, in which the water level sensor 36 and the temperature sensor 37 are incorporated, wherein the control circuit is arranged to realize in each case, the above-mentioned control steps.

If the fog module 100 is put into operation, the result is that cold water mist is generated and out of the grid 26 the front wall 22 flows. As mentioned above, the fog module is 100 are set up to be used in a steam cabin and, in addition, are other applications of the fog module 100 conceivable. In the context of a steam cabin is the fog module 100 Excellent for contributing to a visible vapor effect. A steam cabin has a steam room to which steam is supplied during operation. At times, cold water mist is also supplied to the steam room so that the cold water mist can penetrate the steam, creating spectacular clouds, which are experienced by the user (s) of the steam cabin as clouds of steam. The user then sees / sees this as a confirmation that the steam cabin is working well. In the context of a steam cabin, it is possible that the fog module 100 will operate continuously during the steam process, but this is not necessary. For example, precautions may be taken that are directed to the fog module 100 can be manually activated for a short time to give off a burst of cold water mist to achieve a temporary visible steam effect. It is also possible to have a regulation that is directed to the fog module 100 be automatically activated for a certain period of time and then switch off.

From the above follows that by equipping a steam cabin with at least one mist module 100 in the steam cabin, an ultra-vapor system is realized, that is, a system that can be used to create the desired visible steam effect in the steam cabin as desired. In view of the fact that heat rises and cold sinks, it is favorable for the realization of the intended penetration of the steam with cold water mist when the outlet of the cold water mist is at a higher level in the steam cabin than the outlet of the steam.

Another possible application of the fog module 100 is an application in a refrigerated cabin. This may be a good and energy saving alternative, for example for a cold dip or a cooling booth comprising a conventional cooling system. The fog module 100 is using the mounting box 101 easy to build. Safety can be achieved by applying the Legionella protection system 40 be guaranteed at all times.

It will be apparent to one skilled in the art that the scope of the invention is not limited to the examples discussed above, but that various variations and modifications may be made thereto without departing from the scope of the invention as defined in the appended claims.

For the sake of completeness, it should be noted that where the language in this text is warm and cold, high and low temperatures, this is to be understood as referring to people's feelings of cold and heat.

In summary, according to the invention, there is provided a means for realizing a visible vapor cloud in a vapor space in which one or more persons can sit, generating and delivering steam to the vapor space, further generating cold water mist and delivering it to the vapor space at a position in the vapor space is to come in contact with the steam, and wherein for generating the cold water mist an ultrasonic nebulizer 10 is used. For example, the invention may be applied to a steam cabin by equipping a steam cabin with an ultradampfsystem having a mist device adapted to produce cold water mist and having an outlet to direct the cold water mist into the vapor space of the steam cabin leaving out a position in the steam room to allow the cold water mist to come into contact with steam present in the steam cabin. Other applications are also conceivable for said mist device, for example an application in a cooling booth.
