Description

The accumulator electric household heater is a flat household appliance and can be used as a heating device for heating 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 is described in Utility Model Patent No. 44373 dated February 11, 2004, class F 24 H 1/20, it contains two parallel vertical tanks connected by two connecting pipes and a first heating element installed in one of the tanks. 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. Tanks are located inside the outer, protective housing, filled with thermal insulation. The heating element is mounted on a flange sealed in the lower end part of one of the tanks and is equipped with a thermostat. Additionally, the electric water heater has a second heating element.

A control panel with a thermostat control knob and power mode switches for the heating elements is installed on the protective case. The lower part of the protective housing is equipped with a safety cover.

The disadvantage of this device is the inability to use this device in a horizontal position. This limits the operational capabilities of the device.

In addition, this device is uneconomical due to the formation of scale inside the tanks and on the heating elements.

This device is short-lived due to corrosion of tanks.

The objective of this utility model is to expand operational capabilities, increase its efficiency and durability. The problem is solved due to the fact that the accumulator household electric heater contains an internal container made of stainless steel, consisting of segments and horizontal plates interconnected by anti-corrosion welding along the outer contour and made in the form of a flat oval, the outer case is insulated with heat insulation with upper and lower end caps with latches, the housing of the heating elements covered with porcelain glass enamel, in the hermetic pipes of which two “dry” n heating elements, lower and upper panels installed on the lower and upper end caps, respectively, a hot water intake pipe, a cold water supply pipe made curved, a control panel power supply, a temperature sensor mounted on the upper part of the inner tank, brackets connected to each other, one of which is fixed in the inner part of the outer casing, and the other is on the outer side of it, a control panel mounted on the outer casing, the power supply of which is fixed on the lower end cover.

This design of the electric heater is illustrated in Fig. 1 and contains an internal container 5 made of stainless steel, consisting of segments and horizontal plates interconnected by anti-corrosion welding along the outer contour, forming a flat oval shape. The horizontal plates of the inner container 5 are stitched with a large number of holes, ensuring the unhindered penetration of water from the lower part of the inner container 5 to the upper. In addition, the horizontal plates perform the function of stiffeners to prevent deformation of the inner tank 5. The outer case 19 is made with grooves at the edges

and is insulated from the inner tank 5 by thermal insulation 18 of polyurethane foam. The hot water intake pipe 23 is made with a large bend radius and is connected to the red sleeve 14 through the hot water intake pipe 15. The cold water supply pipe 6 is connected to the blue sleeve 10 through the pipe 7 and the safety valve 9 is non-return. The pipe 6 for supplying cold water is bent toward the wall of the inner tank 5. The housing 24 of the heating elements 16 consists of two sealed pipes, covered with glass enamel and attached to the flange 13 with a gasket 11.

Two “dry” heating elements 16 are installed in the housing 24 of the heating elements 16. The magnesium anode 17 is mounted on the flange 13, parallel to the housing 24 of the heating elements. The lower panel 1 and the upper panel 26 are attached to the lower end cover 8 and the upper end cover 4, respectively, with latches.

The control panel 20 is located on the outer casing 19, the power supply 22 of which is mounted on the bottom end cover 8. The temperature switch 12 has a probe and is mounted on the flange 13. It automatically turns off and blocks the operation of the heating elements 16 when the water is heated above the permissible temperature, which ensures operation electric heater in safe mode.

The buttons and bulbs of the control panel 20 control (set) the temperature of water heating and the power of the heating elements 16: 0.75 kW - economical heating, 1.5 kW - fast heating and notifies about this. In addition, in constant mode, the display shows information about the current water temperature and a self-diagnosis function is carried out, which in case of a malfunction (overheating, failure of the heating elements or thermostat) gives an error code to the display and turns off the power.

A light indication of 21 heating elements 16 is installed on the lower end cover 8. For vertical and horizontal

fastenings of an electric heater use an arm 2 and 3. Actually it is one arm consisting of two parts 2 and 3 connected among themselves. In this case, the bracket 2 is fixed in the inner part of the outer casing 19, and the bracket 3 is fixed on its outer part.

The bushings 10 and 14 are made in the form of hexagons, painted in blue and red colors, respectively, which facilitates installation and connection to cold and hot water. Safety check valve 9 relieves excess pressure.

The implementation of the pipe 6 supply of cold water curved provides turbulence (mixing) of cold water, which accelerates the heating of water and makes the electric heater more economical.

The upper panel 26 is designed for ease of maintenance of the temperature sensor 25 installed at the highest point of the inner tank 5. In addition, the presence of the upper panel 26 and the lower panel 1 increases the ease of installation and maintenance of the electric heater.

The location of the housing 24 of the heating elements 16 at an angle to the inner container 5 ensures the economical use of the electric heater in a horizontal position, which expands the possibility of its use (in small and low rooms).

The implementation of the inner container 5 of stainless steel with external welds of horizontal plates and the use of a magnesium anode 17, eliminates the formation of scale, which increases the durability of the electric heater and its efficiency. The magnesium anode 17, reacting with water and providing its softening, helps to increase the life of the electric heater.

Coating the housing 24 of the heating elements 16 with porcelain glass enamel allows the use of “dry” heating elements that do not come into contact with water and prevent the formation of scale on them, which increases the efficiency of heating water. In addition, the housing design

24 heating elements allows you to change them without draining the water, which ensures their change and ease of use.

The execution of the pipe 23 of the curved hot water intake allows you to take hot water from the highest point, both in vertical and horizontal position.

The implementation of this electric heater of a flat oval shape expands the possibility of its use.

The operation of the electric heater in a vertical position is as follows (Fig. 1).

When connecting an electric heater and setting the required temperature and power, cold water enters through the cold water supply pipe 7 and the cold water supply pipe 6 into the internal tank 5. The water, heated by two or one heating elements 16, enters the upper part of the internal tank 5 and from the upper points through the pipe 23 of the intake of hot water and the pipe 15 exits for use. In this case, when the set heating temperature is reached, the temperature switch 12 turns off the operation of the heating elements 16. The temperature sensor 25 does not allow to increase the temperature of water heating above the boiling point, it activates and turns off the heating elements 16, i.e. the temperature sensor 25 further controls the operation of the heating elements 16.

When installing the electric heater in a horizontal position, the work is carried out similarly to work in a vertical position. Even with a partial filling of the tank 5, water is heated. Hot water under pressure is forced out by cold water from the cold water supply pipe 6 and rises. Upon reaching the upper maximum point of the hot water intake pipe 23, it exits for use through the pipe 23 and the hot water intake pipe 15.
