Description

The utility model relates to household appliances and can be used to heat water below the boiling point, for example, in kitchens, bathrooms, etc.

The well-known electric water heater of the storage type described in the patent for utility model No. 49197 dated 10/11/2005 contains an inner tank (inner tank) and an outer case with end caps that are insulated from each other. The inner tank (inner tank) is made of stainless steel and an electric heating element and a hot water intake pipe are mounted on it. A temperature indicator is installed on the outer casing. In the lower part of the outer casing there is a plastic cover with a light indication of the electric heating element.

The disadvantage of this device is the inability to use it from other sources of heating, for example, from AGV and central hot water supply, etc., which limits its operational capabilities.

In addition, this installation is uneconomical due to the lack of temperature control and high power consumption.

The technical result of this utility model is the expansion of operational capabilities by the possibility of using from other sources of heat, which extends the operational capabilities of the device and increases its efficiency.

This goal is solved due to the fact that the accumulator household water heater contains an internal container covered with porcelain glass enamel, a body with end caps that are thermally insulated from each other, a hot water intake pipe and a cold water supply pipe, a heating element casing fixed in the lower part of the internal container and covered porcelain glass enamel, in the airtight tubes of which two air “dry” heating elements are installed, a magnesium anode mounted on the housing of the heating elements, and a mouth in the lower part of the water heater ovlena

a plastic cover, on the front panel of which there is a thermostat knob, a light indication of the operation of the heating elements and a button for switching the power modes of the heating elements and a digital thermometer, while the spiral heat exchanger coated with porcelain glass is connected to the circuit of an external heating source.

The essence of the utility model is illustrated by graphic materials: Fig. 1 - diagram of the storage water heater

The household storage water heater (Fig. 1) contains an inner tank 1 and a housing 2 with end caps - top 3 and bottom 4. The inner tank 1 is covered with porcelain glass enamel, which protects it from corrosion. End caps 3 and 4 are powder coated. Between the inner tank 1 and the housing 2, thermal insulation 5 made of polyurethane foam is installed.

In the lower part of the inner tank 1, the housing 6 of the heating elements is fastened, covered with porcelain glass enamel and made of two sealed tubes installed obliquely to the inner container 1, in which two air “dry” heating elements 7 (heating elements) are installed.

A magnesium anode 8 is mounted on the inner part of the housing 6 of the heating elements, preventing corrosion of the inner container 1 and the housing of the 6 heating elements. A thermal switch 9 is mounted on the inside of the housing 6 of the heating elements, protecting the heater from overheating. The hot water intake pipe 10 is installed vertically and allows water to be drawn from the maximum point of the inner tank 1. The sealed tubes of the housing 6 heaters are installed at an angle to the inner tank 1. The cold water supply pipe 11 is located directly under the sealed tubes of the housing 6 heaters, and has a divider at the end, creating a swirling wave for uniform and quick mixing of hot and cold water. In the lower part of the water heater there is a plastic cover 12, on the front panel of which a handle 17 of the thermostat 13, a light indication 14 of the operation of the heating elements and a button 15 for switching the power modes of the heating elements are fixed. The bracket 16 of the heater is attached to the wall of the domestic premises. Handle 17

thermostat 13 is designed to set the desired power mode.

In the inner tank 1, a spiral heat exchanger 20 is installed, covered with porcelain glass enamel and connected through pipes 18 and 19 for supplying and discharging hot water, respectively, to a central or individual heating system.

A digital thermometer 21 is installed on the plastic cover 12, on the display of which the actual temperature of the water heater is displayed.

The operation of the device (Fig. 1) is as follows.

Through the pipe branch pipe 11, cold water fills the inner container 1. Using the handle 17 of the temperature controller 13, we set the required heating temperature. Using the button 15 for switching power modes, we set the operation mode - weak heating - 1 kW or fast heating - 2 kW.

The heating elements 7 (heating elements) heat the water to the set temperature and through the pipe nozzle 10 of the hot water intake from the highest point of the inner tank 1, the hot water comes out for use. If the temperature rises above a predetermined temperature switch 9, the water heater is disconnected from the network and then turned on.

This design allows you to turn off the power of the water heater and use the heat of the central heating system or individual water heating, for example AGV. In this case, the most economical heating of water is carried out for the consumer. In this case, hot water through the pipe 19 and the spiral heat exchanger 20 enters the consumer through the pipe 18. The digital thermometer 21 allows you to detect the actual temperature at the outlet and, if necessary, by pressing the power mode switching button 15 to bring the heating temperature to the required one. This allows you to interrupt the constant use of electricity for heating water and use for this purpose a spiral heat exchanger 20. All this extends the operational capabilities of the device and makes it more economical.
