Description

This invention relates to techniques for storage and processing of products, in particular to household freezers and refrigerators.

Known household refrigeration devices containing refrigeration and freezers, however, they do not have a standard section for clean melt water. Some of them have small cellular containers [Babakin B.S., Vygodin V.A. Household refrigerators and freezers: Directory / M .: Kolos. 2000, p.183, fig.8.7], which serve to freeze tap water, however, on the one hand, they are too small to satisfy the needs of the average family in such water, and on the other hand, this refrigerator does not provide for the separation of water into clean water and dirty fractions during the freeze-thaw cycle, therefore, when the source water in the water supply is not very high-quality, this does not allow to obtain clean melt water, free of toxic, carcinogenic and mutagenic substances dissolved in it.

There are various devices for producing melt water (RF patents 2274607 C2, 04.20.2006; RF 2128144 C1, 03/27/1999; Japan 5123668 A, 05/21/1993; USA 5113664 A, 05/19/1992), where it is possible to separate the source water into clean and dirty fractions, however, all these units are made in the form of independent original devices.

A device for cleaning (desalting) water (application for the invention of the Russian Federation 94023948 A1, 09/27/1996), selected as a prototype, in which the purification of water from impurities is carried out in a vessel similar to a pan with a lid placed in the freezer. This device is made in the form of two hermetically connected polished vessels having an air or vacuum layer to reduce heat transfer, and a number of heat pipes made of highly heat-conducting materials are installed in the upper part of the lid to accelerate freezing of water. In this device, water is separated into clean and dirty fractions, however, its ability to obtain melt water is small due to design features, which does not allow in practice to effectively freeze a significant amount of source water.

The technical task of this invention is to expand the capabilities of household refrigerators and freezers, which in addition to performing their usual functions: cooling, freezing, sublimating and thawing various products, get clean melt water.

The problem is solved due to the fact that the freezer and / or refrigerator contains a housing in which thermally insulated freezer and / or refrigeration chambers are located, including a section for receiving thawed drinking water, having a tank 1 for filling with water, draining the water, the refrigerant circuit, freezer, refrigerator and section control means.

The section for receiving thawed drinking water is additionally equipped with a removable basket 2 inserted into the container 1, the removable basket 2 is made with a mesh bottom 3, and a valve 8 for draining the water is made in the lower part of the container 1.

Preferably, the section for producing melt water is in the form of a separate chamber.

Preferably, the melt water section is integrated in the freezer and / or refrigerator.

Preferably, the section for producing melt water is provided with an additional circuit for circulating refrigerant.

Preferably, the section for producing melt water has a valve for pouring water from the water supply into the container 1.

Preferably, the freezer and / or refrigerator has an automation unit that controls the operation of the section to obtain melt water according to a given program.

Preferably, the valve 8 for draining unfrozen dirty water is configured to automatically open when filling a removable basket with ice.

In the proposed solution, a serial household freezer and / or refrigerator has a section for receiving melt water, which is made in the form of a separate chamber, or such a section is built into the freezer and / or refrigerator; the freezer and / or refrigerator section for obtaining melt water is provided with an additional circuit for the circulation of the refrigerant; the section for receiving melt water has a valve for pouring water from the water supply into the container; the freezer and / or refrigerator have an automation unit that controls the operation of the section for receiving melt water according to a given program, as well as a valve for draining unfrozen dirty water, which is configured to automatically open when filling a removable basket with ice.

Thus, a new function appears in serial household refrigerators and freezers - obtaining clean melt water. The resulting water is free from toxic, carcinogenic and mutagenic substances dissolved in it that are present in the original tap water, and in an amount sufficient to satisfy the average family's need for melt water.

The proposed section (figure 1) can be integrated into the lower, middle or upper parts of the refrigerator or freezer. It contains a container 1 with weakly conductive walls, a removable basket 2 with a mesh bottom 3, inserted into a container 1, filled to a certain level with tap water 4, a water freezing unit 5 and a control unit 6, powered from an external electrical network 7, and also a valve 8 for plum dirty water.

As means for controlling the operation of the freezer and / or refrigerator, any means known from the prior art is used.

Section for obtaining melt water works as follows.

If it is necessary to obtain melt water, this section is switched on using the control unit 6. In this case, the freezing unit 5 starts to work, and the container 1 is filled either with the help of an improvised vessel or, if there is an appropriate supply of cold water to the refrigerator and / or freezer, by opening valve 10 using the control unit 6.

Cold water, the filling level of which is also controlled by the control unit 6, entering the tank 1 from the water supply, simultaneously penetrates from below through the mesh bottom 3, filling the removable basket 2. Under the influence of low temperatures, this water gradually freezes, and ice 11 (figure 2) begins form from above, since the walls and bottom of the tank 1 are weakly conductive. During the freezing process, the vast majority of impurities will remain in the water, and the resulting ice will be without these impurities. The automation 6 of this device is configured so that the valve 8 opens when the front of crystallizing ice 11, gradually moving down, comes in contact with the mesh 3 of the removable basket 2. In this case, the non-frozen part of the water, together with impurities, is drained into a special container 12 located outside the freezer or refrigerator, or disposed of in a sewer.

Then, the removable basket 2 with pure ice is either removed from the section for obtaining melt water and placed in conditions with a positive temperature, or conditions conducive to melting ice are formed in the section itself. When ice is thawing, the resulting pure water is used as intended.

The technical result of this invention is to expand the capabilities of household refrigerators and freezers, which in addition to performing their usual functions: cooling, freezing, sublimating and thawing various products to obtain clean melt water.
