RU79648U1 - ELECTRIC WATER HEATER HOUSEHOLD - Google Patents

Abstract

The utility model relates to household appliances and can be used to heat water in domestic and office buildings. The electric heater contains two tanks 1 and 20, connected in series by an adapter pipe 11. Tanks 1 and 20 are made of aluminum and strengthened in three places by couplers 22 with gaskets 21. Tanks 1 and 20 are thermally insulated from the outer case 26. Each tank 1 and 20 has heating elements 3 and 4, respectively. Use the control knob 19 of the control panel 2 to set the desired temperature for heating the water. Through the pipe 12, cold water enters the tank 20, is heated and through the pipe 15 enters through the adapter pipe 11 into the hot water supply pipe 10 of the tank 1, and through the hot water drain pipe 24 it goes to the consumer. 1 p.

Description

The utility model relates to household appliances and can be used to heat water below the boiling point in domestic and office premises.

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 pipe is located at the bottom of one of the tanks, and the hot water outlet is located at the top of the other tank. Both tanks are located inside a protective housing filled with thermal insulation. The heating elements are mounted on flanges that are hermetically seated at the bottom of the end of the tanks. The inlet pipe for supplying cold water is equipped with a check valve, and the connecting pipes connect the adjacent walls of the tanks in their upper and lower parts. The control panel is located on the outer case, and the safety cover is located on the bottom of the outer case.

The disadvantage of this design is the presence of magnesium anodes mounted on the flanges of the heating elements and designed to protect welds from corrosion. Magnesium anodes quickly fail, and replacing them is very difficult, which reduces the maintainability of the electric heater and increases the cost of the device as a whole.

The objective of this utility model is to increase the efficiency, maintainability and durability of the electric heater. The problem is solved due to the fact that the electric storage heater contains a steel outer casing, two containers,

made of aluminum, connected in series with each other by an adapter pipe, a heating element installed in each tank with a thermal switch, a cold water supply pipe with a non-return safety valve in one tank and a hot water intake pipe and a complete drain pipe in another tank, and on the front of the outer case there is a control panel with a control knob with a temperature controller, a button for switching on the operating modes of the heating elements and light indication.

The essence of the utility model is illustrated by graphic materials, where Fig. 1 shows a diagram of a storage electric domestic heater in three forms (front, side and bottom).

The storage electric household heater (Fig. 1, front view) contains two containers 1 and 20, connected in series by an adapter pipe 11. Tanks 1 and 20 are made of aluminum and reinforced in three places with tie-clips 22. Between each container and couplers- gaskets 21.

The outer casing 26 is made of steel and has a top 27 and a bottom 28 end caps made of plastic. Capacities 1 and 20 are thermally insulated from the outer casing 26 and the upper 27 and lower 28 end caps with thermal insulation 23 of polyurethane foam. At the base of the lower part of each tank 1 and 20, heating tanks 3 and 4 are installed by screwing on the thread. At the base of the lower part of the tank 20, a cold water supply pipe 12 is installed, with a blue sleeve 13. On the cold water supply pipe 12, a non-return safety valve 14 is installed, which prevents water from draining into the system and draining water at overpressure. The hot water intake pipe 15 is welded into the base of the vessel 20 and connected through the adapter pipe 11 to the hot water supply pipe 10. A pipe 24 for draining hot water is welded into the base of the tank 1, the outlet of which is fixed a red sleeve 9. At the base of the tank 1 is also welded pipe 5 full drain of water with a plug 6 and a blue sleeve 7. In the lower

parts of the bases of the containers 20 and 1 are fixed contact thermal switches 16 and 8, respectively. On the front of the outer casing 26 there is a control panel 2, on which a control knob 19 with a temperature controller, a button 17 for activating the operating modes of the heating elements 3 and 4, and a light indication 18 are fixed.

In the upper and lower parts of the rear wall of the outer casing 26 (Fig. 1, side view), brackets 25 are arranged for fastening the water heater.

The operation of the device is as follows.

Use the control knob 19 with the temperature controller to set the desired temperature for heating the water. Cold water through the cold water supply pipe 12 enters the tank 20, 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 goes to the consumer through the hot water drain pipe 24.

If it is necessary to increase the water temperature for the consumer, the heating element 3 is switched on with the button 17 and goes through the hot water drain pipe 24 to the consumer. At the same time, on the control panel 2, the indicator light 18 lights up.

The use of the proposed technical solution increases the efficiency and maintainability of the electric heater by simplifying the design (eliminating magnesium anodes and making aluminum containers). In this case, the durability of the device increases.
