Description

Technical field

The present invention relates to a device for cooling drinking liquids, preferably drinking water, which contains at least a supply and a drain for water, an internal container containing ice and / or liquid, and an external container containing drinking liquid.

State of the art

Many devices for cooling drinking liquids are known in the art. So, in conventional devices for storing and bottling chilled beer, the necessary cooling is done by a bath of cold water. The drink flows through a coil completely immersed in a container of cold water. In this case, the temperature regime of cold water is maintained using a refrigeration circuit containing a compressor. Such a construction is described, for example, in patent application DE 202006013990 U1. In addition, refrigerators for drinks are known in which a coil with drinking water is poured into an aluminum block together with a coil of an evaporator of a refrigeration circuit containing a compressor. Such a construction is described, for example, in patent application DE 8026851 U1.

Modern water cooling devices function as storage systems, inside which the temperature regime of drinking water is supported by hoses or protrusions with refrigerant. These hoses or protrusions are cooled using compressor refrigeration circuits, as described, for example, in patent application DE 4039385 C2. In this regard, patent application DE 2147222 A1 describes a device for cooling drinks using a bar-shaped latent heat exchanger, which is immersed in a drink or in a container with a drink and, thus, maintains the temperature regime of the drink.

The disadvantage of all these solutions, available at the prior art, is the comparative complexity of the design, the demanding for service due to the complex structure and, in part, the disadvantage from the point of view of hygiene due to direct contact of the cooling elements with drinking liquid.

Disclosure of invention

Based on the prior art, the objective of the invention is to develop a device for cooling drinking liquids, which will have a simple and less expensive design and differ in favorable hygienic properties.

The problem is solved by the features described in paragraph 1 of the claims. Advantageous embodiments of the invention, which can be used individually or in combination with each other, are disclosed in the dependent claims.

According to the invention, a device for cooling drinking liquids is based on the features of the restrictive part of the claim and is characterized in that the drinking liquid in the external container can be cooled due to surface contact with the internal container.

The result is cooling of drinking liquids, significantly improved compared to the prior art. According to the invention, the device for cooling drinking liquids is characterized by a very compact and very inexpensive system structure, and also provides the most rational use of the installation space. The compact structure, in turn, guarantees low losses of cold in the system, so that the device compares favorably with energy consumption. Due to the lack of direct contact of the cooled drinking liquid and ice, the device according to the invention has advantages from the point of view of hygiene.

According to a preferred embodiment, the device consists of metal and / or plastic. If the device is made of metal, then it can consist of two containers, if it is made of plastic, then it can be made as a whole, for example, a blown part.

An especially advantageous option is that in the lower part of the inner tank there is a sump for melt water. It improves water cooling, as it improves the transfer of cold from ice to the walls of the inner tank.

Also advantageous is the option in which the device comprises an ice maker that produces the necessary ice.

In this case, a variant in which the device comprises a feeding mechanism by means of which ice is transferred to the internal container is particularly advantageous. In this case, the device may also have an automatic control unit, which, by measuring the current temperature, determines the need for ice and, using a feeding mechanism, guarantees the production of an appropriate amount of ice and / or its transfer to the cooled internal cavity.

Also advantageous is the option in which the device for cooling drinking liquids has a connection in the form of a channel between the water supply and the water drain, and cooled drinking liquid can be transported through this connection. This preferred embodiment allows flow cooling of the liquid to be realized.

It turns out to be particularly advantageous in which the device for cooling drinking liquids contains a connection in the form of a channel surrounding an internal container like a spiral. Such a construction advantageously guarantees a particularly efficient transfer of cold from the inner tank to the outer tank. In addition, this preferred embodiment provides a particularly compact design.

A device for cooling drinking liquids guarantees high. cooling power with efficient energy consumption and low installation space requirements.

Brief Description of the Drawings

The invention is described in detail below on the basis of the options presented on the figures, which depict:

Figure 1: schematic view of a preferred embodiment of a device for cooling drinking liquids.

Figure 2: schematic view of a preferred embodiment of a device for cooling drinking liquids.

The implementation of the invention

The same or essentially the same elements have the same designations in the figures.

1, for the purpose of explaining the invention, a perspective schematic view of a preferred embodiment of a device 1 for cooling drinking liquids is taken, taken at an angle from the front. In this case, the device 1 contains a supply of water 2, as well as a drain 3 of water. In addition, the device 1 contains an internal container 4, as well as an external container 5. In the internal container 4 there is a liquid 11 and ice cubes 11, which in this case are used as phase transition material and give off cold when melting. Cold is transferred to the outer wall 7 of the inner container. The inner tank 4 is surrounded by an external tank 5. A water supply 2 and a drain 3 of water are connected to the external tank and provide fluid exchange inside the external tank. Through the outer wall 7 of the inner container 4, the liquid 9 in the outer container 5 is cooled. In this figure, the liquid 9 in the outer container 5 is shown in gray shading. In the upper part of the outer container 5, a boundary 10 is shown between the liquid and the surrounding air. Inside the inner container there are ice cubes 11 or liquid 11. Preferably, this embodiment works according to the storage system: in this case, the liquid to be cooled is supplied to the external container 5 through the water supply 2 and is cooled due to surface contact with the internal container 4. After cooling, the liquid is discharged 3 runoff for water. With sufficient cooling power of the inner tank 4, cooling can also be carried out by the flow method, in which a constant amount of water is simultaneously supplied and discharged.

Figure 2 presents another preferred embodiment of the invention. The device 1 for cooling drinking liquids contains a supply 2 for water and a drain 3 for water. In the inner tank 4 there are ice cubes 11, as well as liquid 11. The inner tank 4 is surrounded by an external tank 5. This external tank 5 has a connection 6 in the form of a channel that connects a water inlet 2 and a water outlet 3. A compound 6 having a channel shape flows with a cooled drinking liquid. Through the outer wall 7 of the inner container 4, the cold is transferred to the liquid 9 located in the outer container 5, and from it to the connection 6 in the form of a channel. This embodiment advantageously allows water to be cooled in a flowing manner.

The subject matter to be protected is as follows. The invention relates to a receiving container for ice cubes, which at the same time contains a storage tank for drinking water / drink with the aim of cooling it using a latent ice exchanger. The device can consist of two containers (in the manufacture of metal) or can be made as a single piece of plastic (for example, in the form of a blowing part). The inner tank contains ice and thereby cools the water in the volume between the two tanks. To improve water cooling, a small sump for melt water may be provided in the lower region of the inner tank. The ice needed for this design is produced by an ice maker. Water flow cooling in this design is possible if there is a channel connection between the inner tank and the outer tank. Such a connecting element must be twisted in a spiral around the inner container and extend from the water inlet to the water outlet, that is, conduct water along a cold surface. This invention is advantageous in that the system is compact, maximally rational use of the installation space and hygienic, since there is no direct contact between ice and the cooled liquid.

The device for cooling drinking liquids guarantees high cooling capacity with efficient energy consumption and low installation space requirements.
