Description

An accumulator household flat water heater is a stationary household heating device designed to heat water below the boiling point in domestic, office premises with the possibility of using hot water at several points (kitchen, bathroom, toilet).

A known storage type water heater is described in utility patent No. 44373 dated 02/11/2004, it contains 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 hot water outlet, located at the top 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 disadvantage of this device is the inability to use it with other sources of heat, which limits its operational capabilities, the complexity of manufacturing, the fragility due to corrosion of the heating elements and welds of the inner tanks, the inability to replace heating elements during repairs without draining the water, high cost, increased size altitude due to non-use of the area between the tanks.

The technical result of this utility model is the expansion of operational capabilities by connecting to a central or individual heating system, increasing efficiency, durability, reducing overall dimensions.

The problem is solved due to the fact that the storage water heater is flat, contains an internal tank,

made of stainless steel, and made of segments and horizontal plates interconnected by anti-corrosion welding, a heat-insulated outer casing with upper and lower end caps on latches, with upper and lower panels mounted on the upper and lower end caps, respectively, the heating element casing, covered with porcelain glass enamel, in the hermetic tubes of which two air heating elements are installed, a hot water intake pipe and a cold water supply pipe with a dissector a control panel with buttons for regulating the temperature and power modes of the heating elements and a digital thermometer located on the outer casing, a temperature sensor, a thermal switch and an arm, and at least two spiral heat exchangers are mounted in the cylindrical segments of the internal container and are equipped with pipes for supply and removal hot water from a central or individual heating system.

The accumulator household flat water heater is shown in Fig. 1. The water heater contains an internal container 5, consisting of segments and oval-shaped plates made of stainless steel with external welds along the contour.

Plate capacity 5, stitched with holes, create rigidity.

The outer case 6 is made with grooves at the edges, which allows you to snap the upper 4 and lower 7 end caps using latches. The inner container 5 is made of segments and horizontal plates interconnected by anti-corrosion welding along the outer contour.

The inner container 5 and the outer case 6 are isolated from each other by thermal insulation 23, which reduces heat loss. A hot water pipe 11 is vertically inserted into the inner container 5 through the pipe end of the hot water pipe 12 with the red sleeve 14, which allows hot water to be taken from the highest point of the water heater. A safety check valve 10 is connected to the cold water supply pipe 9, through which excess

pressure. The cold water supply pipe 8 has a divider that provides high-quality mixing of water for quick heating.

The housing of the heating elements 15 and the gasket 16 are attached to the bottom of the inner tank 5 at an angle. In the housing of the heating elements 15, two “dry” heating elements 17 and a magnesium anode 19 are installed, which protects the joints from corrosion. The heating elements 17 are located in the sealed tubes of the housing of the heating elements 15, which protects them from scale and allows them to be replaced without draining the water.

The bottom panel 1 and the top panel 26 provide easy access to all functional units and are attached to the corresponding end caps 4, 7.

The control of the power mode and the adjustment of the water temperature are made to the control panel 20 with buttons.

Electronic control allows you to select the power mode and set the heating temperature, which is displayed on the LCD-display.

On the bottom end cover 7 there is a light indication 21 of the operation of the heating elements 17 (heating elements) and their power supply 22.

In addition, in a constant mode, the display panel of the digital thermometer 24 displays information about the current temperature of the water in the water heater. The self-diagnosis function is also useful, which in case of malfunctions (overheating, failure of the heating elements or thermostat) gives the corresponding error code to the display and turns off the power.

The temperature switch 18 automatically shuts off and blocks the heating elements 17 from shutting down in case of emergency heating of water above the permissible temperature and does not allow the water heater to work in emergency mode, and returning to emergency mode, allowing further heating of the water, is carried out only manually.

The buttons on the control panel 20 can control the water temperature and the power of the heating elements 17: 0.75 kW - economical heating; 1,5 kW - fast heating.

The incoming cold water through the pipe 9 and the cold water pipe with a divider 8 will fall into the inner container 5, passes through the plates of the inner container 5, heats up and goes out for use through the hot water intake pipe 11.

The temperature sensor 25, installed at the highest point of the inner container 5, and the thermal switch 18, located on the flange of the housing of the heating elements 15, allow twice to protect the heating elements 17 from overheating.

The implementation of the inner tank 5 with welded brackets 2 reduces the cost of the design.

At least two heat exchangers 27, 28 are mounted in the cylindrical segments of the inner tank 5. Each spiral heat exchanger is equipped with a pipe for supplying hot water 29, 31 and pipes for removing hot water 30, 32 for connection to central or individual heating systems.

The nozzles for supplying hot water 29, 31 are equipped with red bushings, the nozzles for draining hot water 30, 32 are equipped with blue bushings.

Thus, for heating water use the heat of a central or individual heating system, for example, AGV. This extends the operational capabilities of the water heater. In addition, the water in the water heater is heated as economically as possible for the consumer. If the water temperature in the spiral heat exchangers is sufficient to reach the temperature set by the consumer, then the heating elements 17 (heating elements) are turned off, and if insufficient, then the heating elements are switched on only for a short time. The digital thermometer 24 installed on the control panel displays the actual temperature of the water heater.

Thus, the use of this compact design in the form of a flat cylinder allows the heating elements to be replaced without removing it from the mount, without draining the water, saving energy, ensuring reliability and ease of maintenance, reducing manufacturing costs and expanding the functionality of the water heater.
