Description

The inventive utility model relates to electrical engineering, namely to accumulative storage water heaters for domestic premises such as residential premises, offices, country houses, cabins of construction organizations and other objects.

Known electric water heater containing a housing with inlet and outlet nozzles, placed in it coaxially towards each other phase and zero electrodes, at least one of which is installed with the possibility of reciprocating movement, and insulated from the housing conductive rod with a power cable connected to a current source and with a phase electrode, a cavity is formed inside the zero electrode forming its working surface, and the working surface of the phase electrode is placed in the said strips and zero concentrically working surface of the electrode to form therebetween an annular gap (RU Patent for Utility Model № 13083, 2000).

A known hot water reservoir containing a reservoir, in the lower part of which cold water is supplied, and heated water is discharged from the upper part. In the lower part of the tank there is a heat source (TEN), which is covered by a cap with an inlet located below at the bottom to enter cold water into the cap. At the top of the tank is an outlet to which the pipe is connected. The outlet end of the pipe is located above or at the height of the boundary layer created in the tank between the upper volume of hot water and the lower volume of cold water, and moves with it. In this case, cold water heated inside the cap rises through the pipe through the surrounding cold water and enters the reservoir in the region of the boundary layer or slightly higher (European patent EP No. 1171742, 2002).

Also known is a boiler containing a housing, which is made of a complex polymer composition and consists of two layers: internal and external. The inner layer is made of thermoplastic elastomer and is designed for direct contact with water, and the outer layer of the boiler body is formed by many threads or strips of synthetic material coated with resin. The outer layer is sintered, resulting in the formation of a mesh structure that is resistant to relatively high pressures. In the lower part of the working tank are installed: a heating element (TEN), a thermostat and a cold water supply pipe. Hot water is released from the tank by a hot water outlet (German Patent No. 60105123T, 2005 and its analogue patent: EP No. 1254343).

Known household water heater, which contains a thermally insulated working tank, pipes for supplying cold water and the release of hot water. Inside the working tank is placed an electric heating device (TEN). The entire inner surface of the working tank, which has direct contact with water, is coated with silver or titanium and is a product of advanced European technologies. This coating provides corrosion resistance of the working tank, as well as biological treatment of water by its disinfection with silver ions (RU patent for utility model No. 75013, 2008).

The closest in design and technical nature to the proposed utility model is a water heater, which contains a thermally insulated sealed working tank, a cold water supply pipe, a hot water discharge pipe and a heating element located inside the working tank, a silver coating is applied to the outer surface of the heating device (RU patent Utility Model No. 88779, 2009).

The disadvantages of all of the above devices should include limited operational capabilities, since each of the known devices can be installed in only one position, namely only vertically or only horizontally.

The technical problem solved by the claimed utility model is the expansion of the range of efficient storage heaters.

The technical result is the expansion of the functionality of a storage water heater by providing the possibility of its horizontal and vertical installations.

The problem is solved by the fact that the claimed storage water heater, which contains a water tank equipped with a hot water intake fitting and a cold water supply fitting, a heating element with a magnesium anode made with the possibility of connecting to the mains, while the water tank is placed in the housing, the latter is equipped with end caps, the end part of the cold water supply fitting has a distributor configured to change the direction of the incoming cold water flow, the intake fitting hot water is made with a tube placed in the cavity of the tank for water inlet and outlet nozzles for supplying cold water are arranged in one plane and are separated from each other to the end edges of the housing cover.

The body of the water heater is preferably made with a cross-section in the shape of a circle. The water tank is made of steel, preferably cylindrical in shape and rigidly fixed inside the cavity of the housing. The water tank is made insulated from the body. As a heat insulator, preferably polyurethane foam is used, which is placed in the internal cavity of the housing.

The dispenser at the end of the cold water supply nozzle is preferably in the form of a cap that is mounted directly at the inlet of the water tank and allows changing the direction of flow of the incoming cold water. The change in direction is preferably provided by turning the incoming cold water stream in a perpendicular direction, i.e. perpendicular to the forming surface of the water tank. This prevents the upward flow of incoming cold water from flowing and prevents the incoming cold water from mixing with the volume of hot water in the water tank.

A heating element is installed in the water tank. For these purposes, any known heating element can be used, for example, directly contacting with water, or a heating element that is placed in a stainless steel capsule and does not come in direct contact with water (“dry” TEN). The heating element may have a shell of various materials, for example, stainless steel with and without coating, copper. The magnesium anode is widely known for use in various types of heaters; it protects the water tank from corrosion.

The water heater further comprises a control unit configured to be connected to the mains, and a control panel. The control unit can be represented by an electronic power board, an electronic control board, a safety thermostat and a power cord connected to each other with a residual current device. As a protective thermostat can be any known device that shuts off the supply of electricity to the internal circuit of the device when the water is excessively heated (above 95 ° C). On the electronic control board, push-button and adjustment switches are made to control the operating modes of the water heater and adjust the temperature of water heating. The electronic control board may be able to connect a Wi-Fi switch and control the water heater remotely through a WEB page or program on a mobile phone. The electronic power board converts the low-voltage direct current that is necessary for the electronic power board to work from the mains voltage. A circuit with a high current load is mounted on the electronic power board, using a relay high current and voltage are supplied to the heating element. The control panel is located on the external part of the housing, onto which the controls of all the above control devices are displayed.

The housing of the claimed device is equipped with removable end caps, which can be made of metal of various grades, including painted or uncoated. The working end cover is configured to place a protective thermostat on it, an inlet of a cold water supply fitting and a hot water intake fitting. The hot water intake fitting has a tube located in the cavity of the water tank. The specified tube allows hot water to be drawn from the working volume of the tank. The length of the tube of the hot water intake fitting is preferably comparable to the length of the generatrix surface of the water tank, which makes it possible to efficiently draw hot water from the side opposite to the side of the working end cap.

The inlet of the cold water supply nozzle and the outlet of the hot water intake nozzle are placed in one plane, i.e. along the edges of the working end cover of the heater. Since the cold water supply nozzle and the hot water intake nozzle are separated along the edges of the heater body in the same plane, this makes it possible to ensure that the tank is filled with cold water from below and the hot water intake is from above in two positions of the heater installation - vertical and horizontal.

The inventive water heater can be installed both vertically and horizontally, ensuring its intended use.

The inventive device differs from the known composition and relative position of structural elements, namely:

- a water tank is placed in the housing;

- the housing is equipped with end caps;

- the end part of the cold water supply nozzle has a distributor configured to change the direction of the incoming cold water flow;

- the hot water intake fitting is made with a tube placed in the cavity of the water tank;

- the inlet and outlet of the cold water supply fittings are placed in the same plane and separated relative to each other to the edges of the end cover of the housing.

Comparison of the claimed utility model with the prototype allows us to conclude that the criterion of "novelty", since the claimed combination of essential features is not known from the prior art.

The inventive utility model can be made of known materials and using well-known techniques, which allows us to conclude that the criterion of "industrial applicability".

The inventive water heater consists of a housing 1 made of stainless steel, which in cross section has a cross section in the form of a circle. In the cavity of the housing 1 is fixed a water tank 2 made of stainless steel. The cavity of the housing 1 is filled with a heat insulator 3, for example, polyurethane foam. In the cavity of the water tank 2, a heating element (TEN) 4 and a magnesium anode 5 are placed, and a cold water supply nozzle 6 is connected, at the end of which a cold water flow distributor is installed, made in the form of a cap 7. Cap 7 changes the direction of the cold water flow, turning it perpendicular to the incoming stream. The heating element 4 is made in the form of two parallel-connected tubular heaters connected to one neutral wire and mounted on a common sealed flange. The water tank 2 is equipped with a hot water intake nozzle 8 with a tube 9 located in the cavity of the water tank 2, the length of which corresponds to the length of the forming surface of the water tank 2. End caps 10 and 11 are placed from the ends of the housing 1. The inlet of the cold water supply nozzle 6 and the outlet of the hot water intake nipple 8 is located at the edges of the end cover 11 of the housing 1. On the end cover 11 there is a protective thermostat 12, electrically connected to the heating element 4, an electronic power board 13, an electronic control board 14, a power cord 15 with a plug d I mains connection and the device breaker 16 and a control panel 17, placed on the outside of the housing 1. The safety thermostat 12, the electronic power board 13 and the electronic control board 14 constitute a control unit. On the outer side of the housing 1 there are elements of the mounting 18 of the water heater to a vertical surface.

The inventive device operates as follows.

The assembled water heater is installed in a convenient place in vertical or horizontal positions and is connected to the mains by means of a power cord 15 with a plug that connects to the outlet. The water heater is connected to the water supply through the cold water supply nozzle 6, according to the connection diagram specified in the instruction manual. The heating element (TEN) 4 heats the water in the water tank 2 to the temperature set on the control panel 17, and turns off. The heat insulator 3 allows you to keep the water hot in the water tank 2 for a long time. As the water cools, the water heater automatically turns on the heating element (TEN) 4 and maintains the water temperature at a set value (the value is set from 35 ° C to 75 ° C).

When the heater is installed vertically, the flow of cold water entering the water tank 2 through the cap 7 is first distributed on the bottom of the water tank 2, then its level in the water tank 2 rises. The incoming water is heated by heat exchange processes. When filling the working volume of the water tank 2, in its upper part is hot water, which is poured over the upper edge of the tube 9 of the hot water intake fitting 8 and is discharged down through the outlet into the end cap 11.

With a horizontal installation of the water heater, the flow of cold water entering the water tank 2 through the cap 8 is first distributed in the cavity of the water tank 2 along the line of its forming surface, and then the level of cold water rises and passes through the zone of the heating element (TEN) 4, water heats up. Heated water is displaced from the water tank 2 under the influence of the pressure of the incoming cold water and through the open end of the pipe 9 of the nozzle for the intake of hot water 8 is supplied to the consumer. Thus, with a horizontal installation of a water heater, its working volume is fully used and the temperature of hot water does not decrease as it flows.

The inventive water heater provides efficient operation both horizontally and vertically, provides an extension of the range of storage water heaters with high heat transfer per unit surface heat transfer. Ensuring the versatility of the installation of a water heater leads to a reduction in production and logistics costs, because reduces the range of products specifically designed for installation vertically or horizontally.
