Description

The utility model relates to household appliances and can be used to heat water below the boiling point in domestic, office premises with the possibility of using hot water at several points (kitchen, bathroom, toilet).

The known storage type electric water heater described in Utility Model Patent No. 44373 of 02/11/04 contains two vertical tanks arranged in parallel, connected by two connecting pipes. Each tank has a heating element. The cold water inlet is located at the bottom of one of the tanks. The hot water outlet is located at the top of another tank. Tanks are located inside a protective housing filled with thermal insulation. The heating element is mounted on a flange sealed in the lower part of the end part of one of the tanks and is equipped with a thermostat. The cold water inlet is equipped with a check valve. Connecting nozzles connect the adjacent walls of the tanks in their upper and lower parts. The control panel is located on the outer casing. The safety cover is located at the bottom of the outer casing.

The disadvantage of this design is the complexity of the design and low maintainability due to the presence of a magnesium anode, which often fails and requires replacement, which is technically difficult. However, you can not do without a magnesium anode, because it helps protect welds from corrosion, increasing the durability of the device.

The objective of this utility model is to increase the maintainability of the device, as well as the durability of its work.

silicone, connected in series with each other by an adapter pipe, a steel outer casing with upper and lower covers, thermally insulated with polyurethane foam, heating elements with thermal switches installed in the base of each tank by screwing, while a cold water supply pipe with a safety tap is installed in the lower part of one tank a valve and a hot water intake pipe connected to a hot water supply pipe of another capacity, into the base of which a pipe for complete drainage of water with a plug and pipe hot water is drained, and on the front of the outer case, in its lower part, a control panel is installed with an electronic programmer containing an electronic display, buttons for switching on the operating modes of heating elements, buttons for setting temperature modes and an indication lamp.

The essence of the utility model is illustrated by graphic materials, which presents a diagram of an electric heater.

The storage electric household heater contains two containers 1 and 17, connected to each other in series by an adapter pipe 11. Tanks 1 and 17 are made of steel and coated with silicone 19 inside for protection against corrosion. The outer case 22 is made of steel, the upper and lower covers are 23 and 24 respectively made of plastic. The outer casing 22 and the lower and upper 24 and 23 are insulated from containers 1 and 17 with polyurethane foam 18. At the base of the lower part of each container, heating elements 3 and 4 are installed by screwing in the threads. A capillary thermal switch 16 is fixed at the base of the lower part of the tank 17, and a contact thermal switch 8. is fixed at the bottom of the container 1. A cold water supply pipe 12 with a blue sleeve 13 is installed at the bottom of the container 17. A non-return safety valve 14 is installed on the cold water supply pipe 12, preventing draining of water into the system and for draining water at overpressure. The hot water intake pipe 15 is welded into the base of the tank 17 and, through an adapter pipe 11, is connected to the hot water supply pipe 10

through the adapter pipe 11, connected to the pipe 10 for supplying hot water to another tank 1. A pipe 5 for complete drainage of water with a plug 6 and a blue sleeve 7 is welded into the base of the tank 1.

The pipe 20 draining hot water with a red sleeve 9 is welded into the base of the tank 1.

On the front of the outer casing 22, in its lower part, a control panel 2 is installed with an electronic programmer containing an electronic scoreboard, buttons for switching on the operating modes of heating elements, buttons for setting temperature modes and an indication lamp. In the lower and upper part of the rear wall of the outer housing 22 are brackets 21 for mounting an electric heater.

Use the buttons on the control panel 2 to set the required temperature mode: accelerated and economical. Cold water through the cold water supply pipe 12 enters the tank 17, is heated by the heating element 4 and through the hot water intake pipe 15 enters through the adapter pipe 11 into the hot water supply pipe 10 of the tank 1 and enters the consumer through the hot water drain pipe 20.

If it is necessary to increase the volume of water and increase its temperature with the buttons of the control panel 2, we adjust the inclusion of another heating element 3 of the tank 1. At the same time, the set water temperature is displayed on the electronic display.

The use of the proposed technical solution increases the durability of the device by coating the inner surfaces of containers 1 and 17 with silicone 18, therefore, eliminating corrosion of welds of containers 1 and 17. This simplifies the design and increases the maintainability of the device. The ability to control operating modes (turning on one or both heating elements) allows you to save electricity.
