The invention relates to refrigeration, and in particular to small-size thermoelectric generators to obtain pieces of a block of ice used, for example, in the preparation of chilled drinks. Can be applied at the enterprises of trade, public catering, and home offices.

Known thermoelectric ice maker (A.S. USSR №1763818, F 25 C 1/12, 1992, Bulletin 35). This device is used to obtain a thin layer of ice on the elements and may not be used for the preparation of pieces of block ice. Known thermoelectric ice maker (A.S. USSR 1723415, F 25 C 1/12, 1992, Bulletin 12)intended for the preparation of lump tubular ice (classification according to the textbook for high schools “Refrigeration systems”, Moscow, 1991, str-356) in a moving vehicle. Cooling of the hot sides of thermoelectric modules in it is due to the oncoming air flow. thermal conductivity of air is 2.1 kcal/m·h·hail, and water 47.4 kcal/m·h·grad. Therefore, the performance of thermoelectric generators air cooled significantly lower than with running water cooling. Thermoelectric ice maker according to the patent of Russia №2225969, F 25 C 1/12 from 2004 is also for making lump tubular ice and it is also used for air cooling thermoelectric modules. Drip pouring water in laforme, which is applied in this invention, can be effective only in laforme with tubular cross-section, as drop it spreads evenly across the diameter and cools quickly.

Analog of the present invention is an invention, as the USSR №1753213, F 25 C 1/12 (1992 Bulletin 29) “Thermoelectric ice machine”. It contains mounted on a horizontal axis, can be rotated, the cooling unit comprising laforme with zamorajivanie elements. Under laforme and placed thermopile flow heat exchangers. In this thermoelectric ice machine provided by the tank, where water is poured into the cell laforme. But no pre-treatment of water passing through the flowing heat exchangers and poured from the container in laforme. It is therefore possible contamination of the flow channels of the heat exchangers, which reduces the reliability of their work, and the ice of untreated water in laforme turns opaque. In the tank, where water is poured into laforme, not provided for pre-cooling, which makes it possible to reduce the cooking time pieces block of ice in laforme, and therefore, increase the performance of thermoelectric ice machine. In this thermoelectric ldog is nerator not possible education stock of purified ice water with spill it in small portions. It is not automated the process of unloading the pieces of ice from cells laforme, they fall under their own weight. A piece of ice that can hang in the cell laforme due to forces of surface tension, formed in interlayer water during thawing of the surface layer of ice, which reduces the performance and reliability of thermoelectric ice machine.

A prototype of the selected patent of Russia №2122693, F 25 C 1/12 from 1998, “Thermoelectric ice machine”. In the case of the ice machine is installed lofarma with a flat bottom and vertical side walls, which are thermoelectric modules with flow heat exchangers. Cover laforme has rods that marginalise in a piece block of ice with which you can manually unload a piece of ice from laforme. Then, manually, using the button with the ejector, a piece of ice is removed from the terminals. As can be seen from the description, there are manual operations, which increase the time of receipt of the piece of ice, which reduces the performance of thermoelectric ice machine. The process of unloading a piece of ice from laforme for rods, frozen in him unreliable as it is possible, with some effort and lack of freezing cores in the ice, pulling them out of a piece of ice, which may remain in place, laforme. In this thermoelectric ice machine as well as in similar, is not provided for pre-treatment of water passing through the flow channels of the heat exchangers and fill laforme, which reduces the reliability of thermoelectric ice machine and reduces the transparency of the obtained piece of ice. And since there is no pre-cooling of water, pour in laforme, it is not possible to reduce the time of cooking piece block of ice, and therefore, the possibility of increasing the performance of thermoelectric ice machine. It is not possible education stock “ice” purified water and spill it in small portions, for example, for the preparation of chilled cocktails that does not allow you to extend the functionality of thermoelectric ice machine.

The problem solved by the invention is the improvement of thermoelectric ice machine. The technical result consists in increasing the performance of thermoelectric ice machine by reducing the preparation time of the piece of block ice in laforme and its discharge therefrom, to increase reliability by reducing contamination of the flow channels of the heat exchangers, increasing the clarity and transparency derived from water is a piece of a block of ice due to its pre-treatment in the ice machine, in extending the functionality of thermoelectric ice machine, namely, providing educational opportunities in it stock ice water treated with spill it in small portions, for example, for the preparation of chilled cocktails.

This technical result is achieved in that thermoelectric ice maker is equipped with a water filter installed in the housing over capacity and hydraulically connected with it. Therefore, the water poured into the tank, first passes through the filter and is cleaned. Then the purified water from the tank is used to feed laforme, as the capacity hydraulically, through the hydraulic valve associated with laforme. The tank is made with thermoelectric modules and a flow-through heat exchangers on its vertical heat conducting walls. Thermoelectric modules through the heat-conducting walls of the cooled water in the tank to the temperature of ice water (<+10°). The vertical position of the side walls of the container, which are thermoelectric modules, allows water to penetrate through the channels of the flow-through heat exchangers for cooling the heated sides of the modules by gravity under its own weight. The portion of water in laforme obtained from the tank, not only pre-cleaned, but chilled. This allows significantly when cretit cooking time a piece of ice in laforme. As a water filter hydraulically connected to the flow heat exchangers, at their canals running purified water, which significantly reduces the deposition of, for example salts on the walls of the channels, which significantly increases the reliability of work flow heat exchangers. It should be noted that in this invention all hydraulic filter elements, capacity, flow-through heat exchangers, lofarma, drain pipes arranged in series-parallel from top to bottom that allows water to penetrate through them by gravity, without using the water pump, which greatly simplifies the design of thermoelectric ice machine. The presence of a reversible motor provides an opportunity not only to forcibly push the piece of block ice from laforme, opening the flip cover, but also to return the plunger to its original position, closing this again laforme hinged lid and thereby automatically prepare lodoform to fill it with a new portion of water. These activities increase the reliability of the discharge piece block of ice from laforme and reduce the time of auxiliary operations, aimed at training and fill laforme. The analysis shows, due to which the present invention increases the performance and reliability of thermoelectric ice machine in General is om. The presence of the drain pipe with the crane mounted on the outside of the body under capacity and hydraulically associated with it, allows you to use the stock of purified ice water from the tank, pouring it in small portions using a crane, for example, for the preparation of chilled cocktails that extends the functionality of thermoelectric ice machine. The performance of hydraulic connections in the ice machine through the electric hydraulic valves, and sensors for temperature and water level in the tank, electrically connected with thermoelectric modules and electric hydraulic valves, will allow you to completely automate the process of making a stock of purified ice water in the tank and transparent, environmentally friendly piece of block ice in laforme, which also improves the performance of a thermoelectric ice machine. Flood openings in the pusher laforme simplify the process of filling in her portion of the purified ice water from the tank. Running outside of the chassis, under laforme, additional drain pipe, hydraulically associated with running exchangers capacity and laforme allow the use of treated water from them for domestic purposes. The area under laforme allows you to install a glass and load directly into it, the piece is a block of ice, that increases the convenience of operation of thermoelectric ice machine.

Thermoelectric ice machine (figures 1 and 2) includes a housing 1 that is installed in it laforme 2 (figure 2) with thermoelectric modules 3 and a flow-through heat exchangers 4 on its vertical walls and a hinged lid 5 under laforme 2. Over laforme installed capacity of 6. The housing 1 includes a switch polarity 7 (figures 1 and 2), which simultaneously gives a command for unloading a piece of ice 35 of lodoform 2 (figure 2). In the housing 1 above the capacity of the installed water filter 8 (any of the commercially available, for example a membrane, such as “Brook” 1C, Vladimir JSC “Polymersintez”), through which water from the water pipe 33 through the hose 32 enters the tank, pre-diocesana filter. The tank 6 is made with thermoelectric modules 9 and a flow-through heat exchangers 10 on its vertical walls, which are made of heat-conductive. The ice machine is equipped with a drain pipe 11 with a valve 12 mounted externally of the housing 1 under the tank 6, as well as reversible engine 13 engine type DC EP, which can b shall be installed in any location in the housing 1 within and outside. He mechanically through a system of levers 14, screws and nuts (Fig. not shown) associated with the pusher 15 (2 and 5), is made between the vertical walls laforme 2, and with hinged lid 5. Water filter 8 hydraulically, for example through the hose 16, is associated with the capacity of 6 (figure 2), through the hose 17 flow-through heat exchangers 9 of the container 6 and the flowing heat exchangers laforme 2. Capacity 6 hydraulically through the hose 18 is connected with the drain pipe 11. Water filter 6 hydraulically connected to the tank, flow heat exchangers capacity and laforme through the electric hydraulic valves 19, 20 and 21. The tank 6 is hydraulically connected with the drain pipe 11 and laforme 2 through the electric hydraulic valves 22 and 23.

The tank 6 is made with water level sensors 24 and its temperature 25 electrically connected (Fig. shown) with thermoelectric modules capacity and all electric hydraulic valves of the ice machine. The pusher 15 (2 and 5) is made water holes 26, through which the purified, chilled water from the tank 6 through the hydraulic valve 23 is poured into laforme 2 (Fig. not shown). Outside the housing 1, laforme 2 (2 and 1) made additional drain pipe 27, hydraulic hoses 28 and 29 associated with the flow-through heat exchangers 4 capacity and laforme 2. In the housing 1 under laforme 2 made space 30 to set the Cup 31. The hose 32 connects the filter 8 with the water pipe 33, on which is located the valve 34. Figure 2 shows a piece of clean, transparent block of ice 35 downloaded from laforme 2. Figure 1 and 2 shows that thermoelectric ice maker installed on a stand 36 (which can be purchased) for convenience, draining the water from the pipe 27.

Thermoelectric ice machine works as follows.

Press the switch 7 is in position “OHL” (figure 1 and 2), while connected to the mains thermoelectric modules 9 through the voltage Converter from 220 V to 12 V (Fig. not shown) and the electric hydraulic valves 19, 20, 21 (figure 2). The valve 34 water 33 is open and running water through the hose 32 enters the water filter 8 ice machine. Tap water in the filter decimals from harmful impurities and hoses 16 and 17 through the open electric hydraulic valves 19, 20, 21 respectively supplied to the heat transfer capacity of 6 and the flow-through heat exchangers 10 and 4 tanks 6 and laforme 2. In flow heat exchangers 10 and 4 diocesana water moves by gravity under its own weight, through the channels 37 and 38 (Fig 3, 4, 5). These channels due to the purification of water in the filter 8 (2) clogged much smaller and longer the reliable cooling of thermoelectric modules 9 and 3. Diocesana water fills the tank 6 to ur is una, given float sensor 24. He gives the command to activate thermoelectric modules 9, along the vertical, the heat transfer walls of the container 6. Due to the effect of Pelite one side of thermoelectric module 9, which is in contact with the vessel wall 6, is cooled, thereby cooling through the heat-conducting wall and the stock of tertiary treated water 39 in the tank 6. The other side of thermoelectric modules 9 in contact with the flowing heat exchangers 10, is heated (figure 3), the heat from which is given to the flowing, tertiary treated water through the channels 37 of the heat exchangers 10. Thermoelectric modules 9 and the hydraulic valve 20 is enabled as long as the temperature of the water 39 in the tank 6 reaches a given value, for example, +5°C (ice water). The temperature level is set using the temperature sensor 25 (figure 2). Upon reaching a predetermined temperature, the sensor 25 gives the command to open the electric hydraulic valves 22 and 23. Purified ice water when it enters the drain pipe 11 and stops in front of the closed valve 12. Opening it (manually) you can pour small portions purified ice water. When you open the valve 23 and the portion of the purified ice water from the tank 6 can get through the hose 40 through flooded holes 26 of the pusher 15 in laforme 2. Volume portions of water can regulirovanie is, for example, by the time the opening and closing of the hydraulic valve 23. This hydraulic valve gives the command to activate thermoelectric modules 3, located on the vertical walls of lodoform 2. Process cooling water in laforme and heat from thermoelectric modules 3 takes place similar to the same process on the vertical, the heat-conducting walls of the container 6, as described above. The portion of water in laforme 2 is cooled to turning it into a piece of ice 35. Since this piece of ice is formed from re-purified ice water, then in time the formation of the piece of ice is greatly reduced and it is transparent. The command for unloading a piece of ice 35 of lodoform 2 may serve time relay (Fig. not shown). This enables reversible motor 13, and the plunger 15 begins to move downward, opening through the hinge levers 14 hinged cover 5 (figure 2). Specified time relays can also give the command for automatic switching polarity of thermoelectric modules 3. While the cold side of thermoelectric modules 3 a short time becomes heated, and hot and cold surface layer of a piece of ice 35 in laforme 2 thaws, which helps to forcibly push a piece of ice from laforme, for example, in the glass 31, preinstalled on the pad 30 to the pus 1 thermoelectric ice machine. Switching the polarity of thermoelectric modules 3 and the inclusion of the reversible motor 13 for discharging piece block of ice 35 may be done manually, as needed, by pressing the switch 7 (Fig 1 and 2) to position “Wygr.” A piece of ice 35 in laforme 2 can be stored for a long time with automatic lowering the voltage to thermoelectric modules 12 to 6 In order to save electricity. Thus, such a thermoelectric ice maker gives you the opportunity to prepare, store, and retrieve the piece of block ice clean, transparent with greater performance and reliability, and also gives an opportunity to form a stock of purified ice water to spill it in small portions.
