Description

[0001] Device for cooling or frosting glasses

[0002] The invention relates to a device for cooling or frosting glasses using carbon dioxide (CO2) and its accessories.

[0003] According to the state of the art, devices for cooling or freezing glasses are known in many different designs. The generic design of the present invention resembles a glass shower. In this design, a glass is placed over a nozzle surrounded by a perforated support plate or a support grid for the glass. As soon as the glass is placed over the nozzle, a suitable actuation (push button or by pressing the glass against the support) opens the gas flow to the nozzle, releasing CO2 into the glass and subsequently around the glass.

[0004] For example, EP 1568956 A1 discloses a device for cooling or freezing glasses that does not correspond to this design, as it has a ring nozzle located outside the glass. The arrangement of the ring nozzle around the glass requires a different design of the device compared to devices of the above design.

[0005] WO 2016084108 A1 shows a device of the above design. The nozzle is surrounded by a support plate. As soon as a glass is pressed against the support plate (shown in a flower shape), CO2 flows from the nozzle into the interior of the glass. Due to the openings in the support plate, the CO2 flows downwards from the interior of the glass through these openings and rises again outside between the closed inner wall of the device and the glass.

[0006] US 3668888 A and US 3602008 A show similar devices that operate in the same way. The device in US 3602008 A is permanently installed in a housing that surrounds a gas cylinder on the side.

[0007] W02022020873A2 shows a device for cooling or frosting glasses, in which the nozzle is located downwards in an interior of the device, with a collecting container for dry ice snow accumulating at the nozzle located below a support plate.

[0008] The object underlying the invention is to further improve or expand a device for cooling glasses of the type disclosed in W02022020873A2 and its usability.

[0009] To solve the problem, devices and accessories for these devices are proposed according to the appended claims.

[0010] In one embodiment, a device for cooling or frosting glasses with carbon dioxide is proposed, which device has an interior space which is open at the top to accommodate a glass, the interior space being enclosed on all sides by an inner wall, a nozzle and a support element being arranged in the interior space and a glass to be cooled or frosted being movable from above into the interior space and against the support element, the inner wall being open into the interior of the device below the support element and a container, preferably as a drawer, being arranged below in the interior of the device, dry ice forming at the nozzle falling through openings in the support or through openings between the support and the nozzle into the container, the support element being funnel-shaped and the region of the inner wall below the support element also being funnel-shaped and extending below the support element.

[0011] The inner wall is preferably part of a foam part, in particular a rigid foam part.

[0012] Alternatively, the inner wall can be formed by an additional element which is located within the foam part and has openings towards the foam part.

[0013] The openings into the device's interior ensure that the carbon dioxide escaping from the nozzle, which may contain a portion of carbon dioxide snow, and the resulting sound are diverted into the device's interior, so that less carbon dioxide snow and less sound escapes to the outside. This advantageously reduces the device's emissions (in the form of carbon dioxide snow and sound) compared to the state of the art.

[0014] It has been found that a hollow, truncated cone or funnel-shaped support is advantageous because it allows for a better fit of the glass edge to the support. This measure results in less carbon dioxide snow and less sound being released to the outside. The improved fit of the glass edge to the support better directs carbon dioxide snow and sound downward through the openings in the support.

[0015] In the embodiment variant in which the inner wall below the support plate is open into the device interior or is closed with an inner base element having several openings leading into the device interior, it is preferred that a container be arranged below the support plate inside the device interior, with dry ice formed at the nozzle falling into the container through openings in the support plate or through openings between the support plate and the nozzle. The container is preferably accessible or removable through an opening located laterally in the outer wall.

[0016] Instead of a support plate with openings or a support grid, as is common with devices of this type, a support element without openings in the area of ​​the glass wall is preferably used. The support element preferably has a central opening for the passage of the nozzle. The support element preferably has several openings around the central opening for the passage of the nozzle, which openings are located within the wall of a usable glass. These several openings are preferably located entirely within half the radius of the support element.

[0017] In a preferred embodiment, the support plate has a funnel-shaped support area for a glass, and dry ice formed at the nozzle flows into the interior of the device through openings located between the funnel-shaped support area of ​​the support plate and the nozzle. It is preferred that a removable tray be arranged below the support plate, with dry ice formed at the nozzle falling through openings in the support plate into the tray. The tray is also advantageous in the event that foreign objects or liquids enter the device.

[0018] Preferably, the distance between the upper edge of the interior space and the upper edge of the support element is at least 2, particularly preferably at least 4 cm, in particular at least 6 cm.

[0019] In one design variant there is a cavity between the inner wall and the outer wall.

[0020] In one design variant, a sound-insulating material is present in this cavity.

[0021] A preferred variant provides that the support element is formed from elastic material, in particular silicone, or has a surface or support made from elastic material, in particular silicone.

[0022] A preferred variant provides that the device has a sensor which detects the pressing of a glass against the support plate, or has a switch or a button which is actuated when a glass is pressed against the support plate, wherein the device has a valve for releasing carbon dioxide via the nozzle, which valve is opened due to a signal from the sensor or due to the actuation of the switch or button.

[0023] In the device in question, the nozzle and support plate are recessed into the interior of the device. The upper edge of the container wall is preferably at least 3 cm from the nozzle, in particular at least 7 cm.

[0024] The interior of the device is preferably cylindrical.

[0025] The interior preferably offers space for exactly one glass.

[0026] The interior preferably has an inner diameter in the range of 10 to 20 cm, particularly preferably in the range of 13 to 17 cm.

[0027] The inner wall surrounds the support element on all sides or all around.

[0028] In one embodiment, when a glass is pressed against the support plate, a valve for the CO2 is opened for a period of time that is independent of the time the glass is pressed against the support plate. For this purpose, an electronic circuit can be provided that opens a nozzle when the glass is initially pressed against the support plate and closes the valve again after a predetermined or adjustable time.

[0029] The device is preferably activated by pressing a glass against the support plate. The release of CO2 can be achieved by a mechanism that is activated by pressing downwards. The release can be achieved by a magnetic switch or another electrical, electronic, or electromechanical component that is activated by a downward movement. The release can be triggered by a sensor that detects pressure on the support plate. The release can be triggered by a sensor that detects the downward movement of the support plate. In one embodiment, the container below the support plate is accessible through a closable opening in the outer wall, which is located below the support plate on the outer wall of the housing.To close the lockable opening, there may be a flap or a door with a hinged joint on the outer wall, or there may be a slider which can be moved along the outer wall.

[0030] In one design variant, the container is provided as a drawer below the support plate, which can be removed from the side of the device's housing below the support plate.

[0050] The scope of protection is defined by the claims. The description of the figures merely discusses possible embodiments and preferred features with reference to the figures, whereby the invention is in no way limited to the embodiments discussed. Those skilled in the art will be able to combine the teaching of the above-mentioned general section with the description of the figures or the descriptions of the figures for the individual figures.

[0051] Fig. 1 shows an exemplary device for cooling or freezing glasses with CO2 in a first embodiment. The device essentially corresponds to the device disclosed in WÖ2022020873A2, although the device shown in Fig. 1 differs from the device in W02022020873A2 in the structure of the inner wall.

[0052] The device comprises an outer wall 1 and an inner wall 2. The inner wall 2 surrounds the interior of the device, which can precisely accommodate a glass to be cooled. The inner wall 2 is formed by a body 3, which can be made entirely of sound-insulating material. A cavity can be present between the body 3 and the outer wall 1, or, as shown, the body 3 can be adjacent to the outer wall 1.

[0053] The inner wall 2 is open at the lower end. A container 13 that can be removed from the device or is accessible or emptied from the outside is arranged below the open end.

[0054] The interior contains a support element 5 and a nozzle 6. The nozzle 6 is preferably located centrally on the support element 5 and above it. The lower outer circumference of the nozzle 6, which faces the support element 5, can be larger than the outer circumference of the opening of the support element 5. The nozzle 6 and the support element 5 are located on a component or assembly 7. The component or assembly 7 extends downwards into an inner housing 14 of the device. The inner housing 14 protects mechanical and electronic components of the device and ensures that dry ice snow reaches the container 13. As illustrated, the support element 5 preferably has a funnel-shaped support surface. Between the support surface and the nozzle 6 are openings through which carbon dioxide in the gaseous state and in the solid state as dry ice snow reaches the interior of the housing and thus into the container 13.The dry ice snow is thus advantageously collected inside the housing of the device.

[0055] The device shown in Fig. 1 is designed as a freestanding unit, with the outer wall 1 formed by an outer housing element, which is provided at the bottom with a base element 11. The container 13 is accessible from the side of the housing, preferably as a drawer that can be pulled out of the device. The drawer and the outer housing element are preferably thermally insulated. A supply line 8 for gaseous carbon dioxide and a power cable 9 are shown in Fig. 1.

[0056] The device in Fig. 2 is designed as a built-in device. The device is preferably integrated flush into a worktop, in particular a worktop of a piece of furniture, a bar, or a larger device such as a catering cooler. The structure of the interior of the device can be as described for Fig. 1. This means that the inner wall 2 can be formed by a body 3, wherein the body 3 has a funnel-shaped region below the funnel-shaped support element 5. The device can have a flange 48, which can be inserted into a recess in the plate. The device can have an outer housing located beneath the plate. The device has a container 13, which is accessible beneath the plate, preferably in that it can be removed from the side of the device, in particular from the outer housing.

[0057] In particular, a cylindrical inner housing part could be inserted in the cylindrical region of the body 3, which covers the body 3 inward toward the interior, so that at least part of the inner wall 2 is formed by the inner housing part. The inner housing part can have openings 4 that extend toward the body 3, as illustrated by way of example in Fig. 5. In another embodiment, the inner housing part can also form the conical region of the inner wall 2.

[0058] Figs. 1 and 2 schematically depict a relay 15 that interrupts the flow of carbon dioxide after a definable period of time. Relay 15 can be a time relay or controlled by a microcontroller. Preferably, relay 15 de-energizes a valve in the carbon dioxide line after a certain period of time, for example, after 3-6 seconds, causing the valve to close. Relay 15 and / or the microcontroller can be located within inner housing 14 or in a space between inner housing 14 and container 13.

[0059] Fig. 3 shows a preferred variant of the support element 5, which comprises a carrier element 16 and a support 17. For better visibility, the two elements are provided with different dot patterns in the upper view of the figure. The carrier element 16 is preferably connected via rods 18 to a central ring 19, which is located below the nozzle 6 on the component 7. The nozzle 6 can preferably be screwed on, with the screwed-on nozzle 6 fastening the ring 19 to the component 7. The carrier element 16 has a funnel-shaped, inclined outer ring 20, which is connected to the inner ring 19 by the rods 18.

[0060] The funnel-shaped support 17 is preferably positively secured to the support element 16. As shown, the funnel-shaped support 17 preferably has several beads 21 on its underside, which engage beneath the funnel-shaped, inclined outer ring 20 of the support element 16. Preferably, at least one bead 21 is located between each two rods 18. The support 17 is made of an elastic material, in particular rubber or silicone. The support element 16 is made of a rigid material, for example, hard plastic or metal.

[0061] Dry ice snow can be moved downwards along the funnel-shaped support 17, where it flows downwards between the rods 18 and the component 7 and into the container 13. Gaseous carbon dioxide is discharged into the housing interior along the same path and, at least partially, flows upwards and outwards in the area between the funnel-shaped support and the funnel-shaped section of the inner wall.

[0062] Figs. 4 and 5 illustrate the use of the device using the support adapter 22. A support adapter 22 is required when a container to be cooled or frozen does not fit in the interior or is too small to be placed over the nozzle 6.

[0063] Fig. 4 shows an exemplary adapter for large containers and / or containers, particularly jars, with a handle or grip. Fig. 5 shows an exemplary adapter for very small containers, particularly jars.

[0064] In both cases, the adapter 22 has a lower conical portion 23, which fits into the funnel of the support element 5. The adapter 22 has an opening in the center, which runs from its lower end to its upper end, with the nozzle being accommodated in or below the opening. The opening can be cylindrical or conical. The opening can widen or taper towards the top.

[0065] The outer wall of the adapter 22 above the lower conical region 23 can be cylindrical or conical. The outer wall can widen or taper upwards. The adapter has an upper annular surface 24. This surface 24 can be horizontal or conical. This surface 24 can be funnel-shaped and inclined inward or conically inclined outward.

[0066] Preferably, the outer circumference of the adapter 22 is provided with ribs in the lower region. Recesses 36 are located between the ribs. The recesses 36 extend from the lower conical region and end below and spaced from the upper annular surface 24. In the adapters 22 shown in Figs. 4 and 5, the section runs through a recess 36 on the left and a rib on the right.

[0067] As shown in Fig. 4, the adapter 22, in particular the adapter 22 for large containers, can have at least one handle 37, which projects upwards above or protrudes from the upper annular surface 24. The handle 37 is preferably formed by a material tongue that is monolithic with the adapter 22. Preferably, two handles 37 are provided.

[0068] In Figs. 4 and 5, the container 13 is shown with dry ice snow 25. This is a by-product of cooling the containers, particularly the glasses. The accumulation and collection of dry ice snow is particularly advantageous for use in bars, as some cocktails are served with dry ice pellets enclosed in stirring rods known from the prior art. Instead of always having to keep dry ice pellets on hand, the dry ice snow 25 can be easily produced on-site with the device in question. For the described use, however, it is advantageous if the dry ice is in pellet form.

[0069] Fig. 6 shows a press 26 developed for the device in question. Fig. 7 shows a preferred use of the dry ice snow 25 using the press 26. Press molds are known from the food industry in the form of one-piece mats with multiple recesses, in which the mass to be molded is pressed into the recesses and then removed from them. Two-part press devices are also known, in which a mass to be molded is placed between two half-shells.

[0070] The press 26 in question differs from known press molds (e.g. silicone molds) in that it has a three-part construction.

[0071] The press 26 in question comprises two forming elements 27, 29 and a guide element 28. The guide element 28 has at least one through-opening 30, preferably a plurality of through-openings 30. Each of the two forming elements 27, 29 has at least one projection 31, preferably a plurality of projections 31. At least one recess 32 is present in each of the projections 31. A dry ice pellet is shaped by two corresponding recesses 32 in the first forming element 27 and the second forming element 29. Each projection 31 fits into a through-opening 30 in the guide element 28.

[0072] Preferably, each mold element 27, 29 comprises a plate-shaped or shell-shaped base body 33 from which several discrete projections 31 protrude. The projections 31 correspond to several through-openings 30 of the guide element 28, so that the two mold elements 27, 29 can be inserted into the guide element 28 from different sides with their projections 31. The length of the through-openings 30 is longer than the length of the projections 31 of a mold element 27, 29. The length of the through-openings 30 can be approximately twice the length of the projections 31. If the length is less than or equal to twice, the dry ice pellets can be formed exclusively in the recesses 32. If the length is greater than twice, the central region of the pellet is formed in the through-opening 30, so that the pellets have a central, widened bulge. The use of the press 26 is illustrated in Fig. 7.Although the press 26 was developed for pressing dry ice snow and is particularly advantageous for this application as it provides good protection against contact, other uses are not excluded.

[0073] In the first step, the guide element 28 is placed on a forming element 27 so that the projections 31 protrude into the through openings 30. In the second step, the mass to be pressed is distributed and spread on top of the guide element 28 or introduced into the through openings 30 in a targeted manner. The through openings 30 can be provided with a rounded portion or a chamfer on one or both sides to facilitate the penetration of the mass and the projections 31. In the third step, the second forming element 29 is moved from above against the guide element 28 so that the projections 31 of the second forming element 29 move into the through openings 30 and the mass is pressed into pellets between corresponding projections 31. In the fourth step, the second forming element 27 and the guide element 28 are lifted off so that the pellets can be removed from the recesses 32.

[0074] A known use of a dry ice pellet is to place and enclose it in a sealable cage 34 of a stirring rod 35 and then add it to a beverage. The illustrated stirring rod 35 has a hinge at its front end, by means of which one half of the cage can be pivoted relative to the other, with the hinge axis oriented perpendicular to the longitudinal direction of the stirring rod 35.

[0075] However, the technical steps for producing the dry ice pellets, which include producing and collecting dry ice snow in a device for cooling or frosting glasses and pressing this dry ice snow into pellets, are new, since previously dry ice pellets had to be purchased and stored in addition to the stirring rods 35.
