Description

The utility model relates to electric water heating devices and can be used in catering: in canteens, in cafes, in bars, in restaurants, as well as in various institutions and enterprises, including: in educational institutions, in hospitals, in kindergartens , in military units, in passenger cars, etc.

A continuous electric boiler is known, selected by the applicant as a prototype, containing a vessel for preparing boiling water, on the top of which there is a collection of boiling water with a tap for boiling water, and inside the vessel for preparing boiling water, a hollow, removable glass with bent upper edges is bent to the periphery towards the bottom, a collection of boiling water with the formation of an annular channel between the outer surface of the vessel for boiling water and the curved edges of the glass Contents of the invention RF №673819 «Boiler" of 06.03.77., opubl.15.07.79., A 47 J 27/21). The position of the empty glass is not stable, as when boiling and increasing pressure on the bottom of the glass, it can rise with a bias in one direction or another. As a result, the gap above the edge of the vessel for the preparation of boiling water is unstable. As a result of this, as well as the presence of two annular channels inside and outside the vessel for boiling water, it makes it difficult for the resulting vapor bubbles, coated with a shell of boiled water, to pass from the vessel for preparing boiling water to the vessel for collecting boiling water.

The technical task of the claimed utility model is to increase the reliability of the boiler by unhindered passage of vapor bubbles, the resulting vapor bubbles, coated with a shell of boiled water, from a vessel for preparing boiling water to a vessel for collecting boiling water.

The problem is solved by performing a continuous electric boiler containing a vessel for boiling water, on the top of which there is a collection of boiling water with a boiling water tap, and a glass is located inside the vessel for boiling water, according to

utility model, a hole is made in the bottom of the glass, and a lid is fixed on top of the glass, the diameter of which exceeds the diameter of the boiling chamber.

The edges of the lid are bent down.

The hole located in the bottom allows you to fill the glass with water. The position of the glass in the boiling water vessel becomes more stable, and the annular gap between the boiling water vessel and the glass remains stable, because less prone to fluctuations in size. A glass of water is essentially a stabilizer and acts as a damping pad. Bent down the edges of the lid facilitate the descent (rolling) of steam bubbles coated with a shell of boiled water in a vessel for collecting boiling water.

Conducted patent research did not reveal similar technical solutions, which allows us to conclude that the proposed technical solution is new.

The domestic industry has all the means (materials, equipment, technology) necessary for the manufacture of the inventive boiler and its widespread use.

The essence of the utility model is illustrated by the drawing, where Fig. 1 shows a boiler in longitudinal section.

Electric continuous boiler 1 contains a housing 2. In the housing 2 are located interconnected nutrient vessel 3, (or another source of cold water), a vessel for preparing boiling water 4 with tubular electric heaters (heating elements) 5, in the upper part of which there is a vessel for collecting boiling water 6, with a boiling water selection valve 7. Inside the vessel for preparing boiling water 4, a glass 8 is located with a hole 9 made in its bottom. On top of the glass 8 is closed a lid 10, which is mounted on the glass 8. The diameter of the lid 10 exceeds the diameter of vessels for preparing boiling water 4, and its edges 11 are bent down towards the bottom of the vessel for collecting boiling water 6 at an angle of 10-15 °. The vessel for collecting boiling water 6 is equipped with a sensor with contacts for monitoring the maximum water level in the vessel and controlling the operation of the heating elements 5 (not shown in the drawing). A vessel for preparing boiling water 4 may be located inside the nutrient vessel 3, representing communicating vessels. The feeding vessel 3 is connected to a cold water supply system. In the feeding vessel 3 there is a sensor with contacts for monitoring the water level in the feeding vessel 3 and the vessel for preparing boiling water 4 and controlling the operation of the heating elements 5 (not shown in the drawing).

The device operates as follows. After the boiler 1 is turned on, the nutrient vessel 3 and the vessel for preparing boiling water 4 and, accordingly, the glass 8 are filled with water through the opening 9. When the heating elements 5 are completely immersed, the latter are switched on. When the set water level in the vessels is reached, the supply of cold water from the water supply is interrupted. The water in the vessel for preparing boiling water 4 is heated to a boil. As a result of boiling water, the pressure in the vessel 4 increases. The glass 8 rises, while the water level in it decreases, and the gap between the edge of the vessel 4 and the lid 10 increases. The resulting vapor bubbles, covered with a shell of boiled water, rise up into the gap between the edge of the vessel 4 and the lid 10 and carry the boiling water behind them, which, rolling along the edges 11 of the lid 10, enters the inner cavity of the vessel to collect boiling water 6. The lid 10 serves reflector for spray boiling water. The boiling water selection valve opens 7. After filling the vessel for collecting boiling water 6 to a predetermined level, the sensor contact closes and the heating elements are switched off. 5. When the water level in the vessel for collecting boiling water 6 decreases, the heating elements 5 are switched on. At the stage of boiling water and collecting boiling water, the water level in the vessel for preparing boiling water 4 and, accordingly, in a glass 8 decreases. Through the contact of the sensor located in the nutrient vessel 3, there is a command to supply cold water to the vessel for preparing boiling water 4 and, accordingly, to the glass 8. The cycle is repeated.
