Description

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

The well-known electric heater described in the patent for utility model No. 44373 dated 02/11/2004 contains a housing thermally insulated from two internal tanks arranged in parallel, each of which contains a cold water supply pipe with a check valve on the heating element mounted on the flanges , hot water intake pipe, safety cap. One of the heating elements is equipped with a thermostat mounted on the flange. The control panel is located on the front wall of the housing.

The disadvantage of this technical solution is the limited operational capabilities, since this design can only be used with pre-heating water and cannot be used in flow mode. This reduces economy. This design does not provide the necessary durability of the internal containers and heating elements due to corrosion. This design does not allow to work in the mode, using only one internal capacity, which reduces its efficiency.

The solved problem of this utility model is the expansion of its operational capabilities, increasing efficiency and durability.

The problem is solved due to the fact that the instantaneous storage water heater contains serially connected first and second internal containers made of stainless steel, 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 a bend and a divider at the end of the pipe, pipe

hot water intake, four “dry” heating elements and magnesium anodes mounted on the first and second flanges, while two “dry” heating elements, a magnesium anode and a capillary thermal switch are mounted on the first flange, in the lower part of the first internal container, and two others dry ”heating elements with a magnesium anode and a contact thermal switch - on the second flange, in the upper part of the second inner tank, an electromagnetic valve mounted on the connecting pipe, a pipe for complete drainage of water, Installed in the lower part of the second internal capacity, and on the front of the case there is a control panel with an electronic programmer.

The inventive utility model is presented in Fig. 1, where in three types the design of this water heater is given.

The instantaneous storage water heater (Fig. 1) contains the first 1 and second 15 inner tanks made of stainless steel and connected in series with each other by a connecting pipe 19 so that the lower part of the second inner tank is connected to the upper part of the first inner tank. The housing 22 with the upper 20 and lower 24 end caps has thermal insulation 16 of the first 1 and second 15 internal containers, made, for example, of polyurethane foam. The end of the cold water supply pipe 8 is made curved and a divider is mounted on it, which carries out a directed circular movement of water in the lower part of the first 1 inner container, which contributes to uniform heating of the water. The other end of the cold water supply pipe 8 is equipped with a non-return safety valve 10 and a blue sleeve 9. A hot water intake pipe 13 is connected to the lower part of the second 15 of the internal tank, connected to the connecting pipe 19 and the electromagnetic valve 11, which switches the operating modes from accumulative to flow and back.

In the lower part of the second 15 of the inner tank mounted pipe 12 for complete drainage of water.

In the lower part of the first 1 inner container and in the upper part of the second 15 inner container, the first and second flanges are installed, respectively. Two “dry” heating elements 4 mounted in a glass case 3, a magnesium anode 5 and a capillary thermal switch 6 are mounted on the first flange. Two two “dry” heating elements 4, a magnesium anode 5 and a contact thermal switch 18 are also installed on the second flange.

The upper 20 and lower 24 end caps have plastic caps 17 and 7, respectively, designed to change the elements mounted on the flanges. On the front of the housing 22 mounted control panel 2 with an electronic programmer that provides a preset mode of operation.

For mounting the water heater on the rear of the housing 22, a bracket 21 and an emphasis 23 are fixed, allowing the water heater to be installed strictly vertically.

The operation of the water heater is as follows.

Cold water through the pipe 8 for supplying cold water enters the first 1 inner container and through the connecting pipe 19 enters the second 15 inner container. Depending on the operating mode installed on the electronic programmer of the control panel 2, two “dry” heating elements 4, a magnesium anode 5 and a capillary thermal switch of the first 1 internal capacity providing a storage mode, or two “dry” heating elements 4, a magnesium anode are turned on 5 and a contact thermal switch 18 of the second 15 internal capacity, providing a flow mode of operation, or both internal capacities 1 and 15, providing a cumulative mode. Solenoid valve 11 is working

only in flow mode, blocking the connecting pipe 13, ensuring the operation of the second 15 internal capacity in flow mode.

If necessary, pipe 12 is turned on to completely drain the water.

Using the proposed design of the water heater (Fig. 1) allows it to operate in flow and storage mode, which extends the functionality of the device.

This increases the efficiency of the water heater due to the possibility of using one of the internal containers 1 or 15. The presence of plastic covers 17 and 7 allows to improve the maintainability of the water heater due to better access to replaceable elements.

The implementation of the internal containers 1 and 15 of stainless steel, as well as the use of a magnesium anode, increases the life of the water heater by eliminating corrosion.

In addition, this water heater can be used not only from electricity, but any other energy source can be used.
