Description

The subject of this invention is a mono-block device for icing, frosting or

mist, a glass or

hollow body containers.

  This invention relates to the technical sector of refrigeration and cooling.

  To obtain this icing, this fogging or this icing, the principle of expansion of a gas in liquid phase maintained in a tank or bottle using compression is used.

  The first characteristic of the mono-block device is that it consists of a tank or a bottle containing under pressure a gas in liquid phase which, after opening, is evacuated by any means allowing to be 100% in liquid phase to a valve (this being integrated into the body of the device) serving as expansion and transformation chamber, thanks to the path taken by the gas inside this integrated valve, connected to a means diffusion which will serve as a time delay and will finalize the transformation into an ideal gas-liquid state before opening into a final expansion chamber, constituted by the internal walls of the container or hollow body placed on the plate, allowing cooling from the interior of this container or hollow body and the formation of frost, due to the fixation of the ambient vapors contained in the air, on the external walls.

  In addition, it comprises a projection nozzle and means for controlling, from the support means of the glasses or hollow containers, the opening or closing of an integrated valve 20 which distributes the gas to the nozzle and to the frosting container.

  Another characteristic of the mono-block device lies in the fact that the integrated valve and the diffuser means cannot be separated to allow 100% liquid transformation from the start to the ideal gas-liquid state on arrival. Indeed, the diffuser means attached to the integrated expansion valve 25 will finalize the heat exchange and will serve as a time delay for the passage of gas.

  For that it will have to be judiciously dimensioned and carried out in one o several coils.

  According to other characteristics: - the body of the device has a drainage of condensation water - it can undergo a surface treatment (anodization), without altering its functioning.

  These characteristics and others will emerge from the following description.

  To fix the subject of the invention, without however limiting it, in the appended drawing: FIG. 1 and a schematic sectional view of the mono-block device according to a preferred but non-limiting embodiment. The mono-block device is shown in the rest or closed position.

  Figure 2 and similar but the mono-block device being in operation.

  Figure 3 is a sectional view of the diffuser means on a larger scale.

  In order to make the object of the invention more realistic and concrete, it will now be described in a nonlimiting manner with reference to the examples illustrated by the figures in the drawing.

  The mono-block device consists of a tank o existing bottle, o to be added during the acquisition, containing a liquid gas (50 bars at 15 degrees Celsius for carbon dioxide).

  If the reservoir or bottle exists, then a double tap is enough to supply the object of the invention. If it does not exist, a complete installation is to be expected. Thanks to the flexible supply hose, the mono-block device becomes mobile on the surface o it is in service, o can be fixed on this surface thanks to the thread made on the body (1) of the mono-block device .

  The gas, in the liquid phase, is drawn from the bottom of the bottle via a dip tube 20 or by inverting the bottle or by any means allowing this gas to be conveyed to an integrated valve forming part of the mono-block device as will be shown in the following description. Note that the liquid gas is kept at the bottom of the bottle by the gas formed in the unfilled part of said bottle.

  Preferably, carbon dioxide (CO2) is used as the liquid phase gas and more generally any liquid gas which creates cold when it is relaxed.

  The need to control the expansion of this gas is due to the fact that if one relaxes this gas at the outlet of the valve closing the bottle, carbon dioxide snow is created.

  This is why, the gas is channeled in a diffuser means acting as timer, heat exchanger, arriving from an expansion chamber, located in an integrated valve (2) to bring the gas into a gas-liquid state, ideal end state. This diffuser means opening out at the center of a plate (5) on which a container (R) is placed.

  The internal walls (Ri) of this container forming a final expansion chamber, the thermal reaction between the internal and external walls of this container aims to create frost on the external walls of the container or hollow body, if it is suitably arranged on the plate (5) into which the diffuser means (4) opens.

  This diffuser means (4) acting as a timer and heat exchanger is formed by one or more capillaries (6) arranged in one or more coils judiciously sized according to the nature, shape and dimensions of the container or hollow body.

  Obviously, depending on the uses and the gases used, the capillary (6) may consist of a simple conduit receiving at the end a diffuser.

  According to a preferred embodiment of the invention, but not limiting, we have the body (1) of the mono-block device which integrates the valve (2) from which the diffuser means (4). of the body (1) is the tray (5) receiving the container (R) or hollow body into which the diffuser means (4) opens.

  In order to have a good centering of this plate (5) inside the body (1) a centering system will be put in place. Between the body (1) of the mono-block device and the underside of the plate (5) will be arranged a flexible operating spring. The mono-block device thus produced in a compact manner can be fixed either directly on the work station, or in an annex piece of furniture, or in a box of any compatible material, in order to make the mono-block device mobile.

  The connection of the mono-block device and the tank or bottle will be made by means of a suitable hose. The integrated valve (2), in the body (1) of the mono-block device, receives a piston (3) fitted with seals (IOa, 1Ob), is mounted in the axis of the mono-device -block, therefore in that of the tray (5) receptacle of the container (R) o hollow body. This container (R) o hollow body, receiving a manual and vertical thrust (P) from top to bottom, the plate (5) fitted with an adjustment screw will press the piston (3) which will allow the passage of gas stored in the body of the integrated valve (2).

  When the thrust is stopped (P), a spring (7) will close the piston (3) and maintain the seal in the rest position of the mono-block device.

  We note in the body of the mono-block device (1), two recesses allowing the passage, on one side of the pipe arriving from the reservoir or bottle, and on the other the passage of the capillary (6) formed in serpentines .

  The operation of the mono-block device according to the invention will now be described: After opening the valve of the tank or bottle, the container (R) or hollow body 50 is placed upside down on the plate (5). Thanks to a manual push on the container (R) o hollow body, thus causing the displacement of the plate (5) vertically downwards, one obtains jointly a push on the piston (3) and the release of the passage of the gas under pressure in the integrated valve (2). Passing through the capillary coil (6) the vapor titer increases.

  While holding the container (R) o hollow body in position, the pressure exerted on it is released. The internal walls of the container (R) o hollow body being therefore cooled by the expansion of carbon dioxide, the water vapor contained in the air is frosted, by reaction, on the external walls of the container (R) o body hollow. Note that the downward movement of the plate (5) compresses its flexible spring and the spring (7), which ensures the closing of the piston, when the thrust is released (P), causing at the same time sealing in the rest position. Note also the flexibility of the capillary (6) since it is integral with the plate (5).

  It should be considered that the capillary (6) is made of any material compatible with the gas used. Without departing from the scope of the invention, a device allowing the descent or the timed ascent of the platform (5) may be provided.

  Likewise, the opening and closing system of the integrated valve (2) as well as its operating principle can be modified.

  This invention is not limited to a single mono-block device per tank or bottle. Similarly, the mono-block device can be bare to be fixed directly on a work surface, o receive a covering giving it any desired presentation.

  The mono-block device produced according to the invention is used in particular, in its primary role for frosting glasses to serve drinks, and thus refreshments, can also be used for other applications. The means will be adapted for the desired uses.

  The advantages are apparent from the description and in particular: - The simplicity of manufacture.

- Utilisation facility.

  The invention is in no way limited to that of these modes of application any more than to those of embodiments of these various parts having been more particularly indicated. On the contrary, it embraces all variants.
