Description

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

A storage type water heater is known (RU patent for utility model N44373, 2004), which comprises two parallel vertical tanks connected at the top and bottom by pipes, an inlet pipe for supplying cold water located in the lower part, and an outlet pipe for leaving hot water located in the upper parts of another tank. Tanks are located inside the outer protective casing, filled with thermal insulation. Two heating elements are mounted on the sealed flanges of each tank. The water heater is equipped with a remote thermostat. On the outer casing there is a control panel with a thermostat control knob and power mode switches for the heating elements. The lower part of the housing is equipped with a safety cover.

The disadvantages of this device are limited operational capabilities, the complexity of manufacturing, fragility due to corrosion of the heating elements and the inability to replace them during repair without draining the water, increased overall dimensions, including the depth dimension. Known design can only be used with pre-heating water.

Known domestic electric heater for hot decentralized water supply of premises, which contains vertically arranged two tanks connected by two pipes, the upper tank is equipped with a cold water supply pipe, the lower one has a hot water discharge pipe, and heating elements located in the lower part of the tank cavity, the exhaust pipe hot water is located in the bottom of the lower tank, and its inlet end is brought into the upper part of the cavity of this tank. The output end of the connecting pipe is brought into the lower part of the cavity of the lower tank in the area of the heating element, and the second connecting pipe is a pipe equipped with a valve and located between the bottom of the upper tank and the top of the lower tank (RU patent on invention No. 2116580, 1998).

In a known water heater, only one of the tanks is insulated, namely the lower one, which has a lower capacity, which leads to heat loss and, consequently, to an increase in energy consumption. The disadvantages of the known electric heater should also include the presence of three valves that ensure the operation of the device, which is controlled manually.

A known hot water system with a heat pump (application JP 3-173204, 2001), which contains several, for example two, parallel installed tanks for hot water, a water heater with a heat pump, a circulation circuit in which water circulates between the water heater and tanks and heated to a boil. The known system also includes a supply pipe for cold water connected to the bottom of the tanks; a hot water pipe connected to the top of the tanks; electric water heaters built into the tanks, as well as multi-way valves. One of the valves selectively connects the tanks to the circulation circuit, and the other selectively connects the corresponding tank to the cold water pipeline.

The disadvantages of the known electric heater include significant heat loss that occurs as a result of the lack of tanks insulation in the design of the device, which leads to additional heat loss and, consequently, to increased energy consumption. In addition, the design of the electric heater has a high energy intensity, due to the presence of a heat pump in the water circuit, as well as a complex system for switching tanks to the circulation circuit and to the cold water pipeline.

Closest to the proposed one is a instantaneous storage water heater, which contains first and second internal tanks made of stainless steel in series, a housing with upper and lower end caps, insulated from each other, a cold water supply pipe with a non-return safety valve, made with with a bend and a divider at the end of the pipe, a hot water intake pipe, four “dry” heating elements and magnesium anodes mounted on the first and second flanges, while m two “dry” heating elements, a magnesium anode and a capillary thermoswitch are mounted on the first flange, in the lower part of the first internal container, and two other “dry” heating elements with a magnesium anode and a contact thermal switch - on the second flange, in the upper part of the second internal container a solenoid valve mounted on the connecting pipe, a pipe for complete drainage of water, installed in the lower part of the second inner tank, and on the front of the housing there is a control panel with electronic grammatorom (RU patent for utility model number 71735, 2008).

The well-known water heater has increased operational capabilities, expressed in the possibility of use in both flow and storage modes. At the same time, its operational capabilities cannot be defined as universal, since it can only be installed vertically. In addition, the known water heater has a complex structure and increased energy consumption, due, inter alia, to the presence of several heating elements.

The objective of the claimed utility model is to expand the range of efficient storage heaters.

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

The problem is solved by the fact that a storage, storage water heater is declared that contains first and second water tanks communicated with each other and housed in the housing, the latter is equipped with end caps, the water tanks are equipped with a hot water intake fitting and a cold water supply fitting, an end part which has a distributor, a heating element with a magnesium anode, made with the possibility of connecting to the mains, while the heating element is placed in one tank for water, on which a cold water supply nozzle is installed, the distributor of the latter is configured to change the direction of the incoming cold water flow, and a hot water intake nozzle is mounted in another water tank, which has a tube located in the cavity of the water tank, the inlet and outlet of these nozzles are placed in one plane and separated relative to each other to the edges of the end cap, water tanks are communicated with each other by means of nozzles spaced relative to each other along the longitudinal axis and placed on adjacent side surfaces s water tanks.

The housing is preferably oval. Water tanks are made of steel of the same size, preferably cylindrical in shape and rigidly fixed inside the cavity of the housing. Water tanks are made insulated from each other. 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.

The message of the water tanks to each other is made by means of straight nozzles, which are taps that provide a tight connection of the tanks to each other. Additionally, connecting rings are installed on adjacent surfaces of the tanks, which ensure accurate positioning of the tanks relative to each other. These bends are spaced from each other along the length of the generatrix surface of the water tanks, are made on the adjacent sides of the water tanks at the same level, provide the possibility of water circulation between them and uniform heating of the water.

A heating element is installed in the water tank to which the cold water inlet is connected. 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 is not 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 (over 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. On the outside there is a control housing panel, 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 cold water supply and hot intake fittings are routed to the appropriate water tanks. 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:

- placement of the heating element in the water tank, to which the cold water supply fitting is connected;

- the implementation of the dispenser with the ability to change the direction of flow of incoming cold water;

- placement in another tank for water fitting hot water intake with a pipe placed in the cavity of the water tank;

- placing the inlet of the cold water supply nozzle and the outlet of the hot water intake nozzle in one plane and diluting them along the edges of the end cover of the housing;

- communication of water tanks with each other by means of nozzles that are placed on adjacent lateral surfaces of the water tanks and separated from each other.

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 has an oval shape. In the cavity of the housing 1, water tanks 2 and 3 made of stainless steel are mirrored, the cavity of the housing 1 is filled with a heat insulator 4, for example, polyurethane foam. A heating element (TEN) 5 and a magnesium anode 6 are placed in the cavity of the water tank 2 and a cold water supply nozzle 7 is connected, at the end of which a cold water flow distributor is installed, made in the form of a cap 8, which changes the direction of the cold water flow, turning it perpendicularly incoming stream. The heating element 5 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 3 is equipped with a hot water intake nozzle 9 with a tube placed in the cavity of the water tank 3, the length of which corresponds to the length of the forming surface of the water tank 3. The water tanks 2 and 3 are in communication with each other by means of two straight nozzles 10 made for example, from pipes with a diameter of Ø50 mm, and connected by means of connecting rings 11, which are placed on adjacent side surfaces of the water tanks 2 and 3. End caps 12 and 13 are placed from the ends of the housing 1. The inlet of the cold water inlet 7 and the outlet of the hot intake water 9 rasp laid on the edges of the end cover 13 of the housing 1. On the end cover 13 there is a protective thermostat 14, electrically connected to the heating element 5, an electronic power board 15, an electronic control board 16, a power cord 17 with a plug for connecting to an electrical outlet and with a residual current device 18 and a control panel 19 located on the outside of the housing 1. A safety thermostat 14, an electronic power board 15, and an electronic control board 16 constitute a control unit. On the outer side of the housing 1 there are elements of fastening 20 of the heater to a vertical surface.

The inventive device operates as follows.

The assembled water heater is installed in a convenient place in a vertical or horizontal position and is connected to the power grid by means of a power cord 17 with a plug that connects to the outlet. The water heater is connected to the water supply through the cold water supply nozzle 7, according to the connection diagram specified in the instruction manual. The heating element (TEN) 5 heats the water in the water tank 2 to the temperature set on the control panel 19, and turns off. The heat insulator 4 allows you to keep the water hot in the water tanks 2 and 3 for a long time. As the water cools, the water heater automatically turns on the heating element (TEN) 5 and maintains the water temperature at a preset 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 8 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. Since the water tanks 2 and 3 are made communicating, partially heated water flows through the lower pipe 10 into the water tank 3, where it displaces the water heated to the set temperature and coming from the water tank 2 through the upper pipe 10. When filling the working volumes of the tanks for water 2 and 3, in their upper part there is hot water that flows over the upper edge of the tube of the hot water intake fitting 9 and is discharged downward through the outlet into the end cap 13.

When the water heater is installed horizontally, 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) 5 , the water is heated and through the nozzles 10, communicating the water tank 2 with the water tank 3, enters the water tank 3. Heated water is forced out of the water tank 3 under the influence of pressure of incoming cold water and through the open end of the nozzle pipe for Abora hot water 9 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.
