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, comprising a vessel for preparing boiling water connected to a nutrient vessel (a source of cold water), and a vessel for collecting boiling water with a drain pipe (See utility model description No. 422376 "Electric boiler" claim 2 of the formula ПМ, dated 30.05.04., publ. 27.11.04. Н 05 В 1/00, 3/78, A 47 J 31/54, 31/56, Fisenko B.L., Fisenko A.B. Fisenko S.B.)

The location of the drain pipe on the cylindrical surface of the vessel for collecting boiling water does not provide a complete drain of boiling water from the vessel. And when the boiler is turned on to obtain a new portion of boiling water, the newly obtained boiling water will mix with the remaining balance of boiling water, which will ultimately lower the temperature of the boiling water in the vessel.

The technical task of the claimed utility model is to increase the efficiency of the boiler by increasing the temperature of the finished boiling water.

The problem is solved by performing a well-known continuous electric boiler containing a vessel for preparing boiling water and a vessel for collecting boiling water with a drain pipe connected to a source of cold water, in which, according to a utility model, the drain pipe is mounted in the bottom of the vessel for collecting boiling water.

At the same time, the bottom of the vessel for collecting boiling water can be made with a bias towards the location of the drain pipe.

A vessel for collecting boiling water is located on the upper part of the vessel for preparing boiling water.

Placing the drain pipe in the bottom of the vessel for collecting boiling water and performing the bottom of the vessel for collecting boiling water with a slope towards the location of the drain pipe allows the boiler to be completely drained from the vessel and thereby increase the efficiency of the boiler by raising the temperature of the finished boiling water.

Conducted patent research did not reveal similar technical solutions, which allows us to conclude about the novelty of the claimed technical solution.

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, which shows a General view of the boiler.

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 and a vessel for collecting boiling water 6, located on the top parts of the vessel for the preparation of boiling water 4. In the bottom 7 of the vessel for collecting boiling water 6, a drain pipe 8 is mounted for connecting to a tap for boiling water (not shown). And the bottom 7 of the vessel 6 is made with a slope towards the location of the drain pipe 8. The vessel for collecting boiling water 6 is equipped with a sensor with contacts 9 and 10 for monitoring the maximum water level in the vessel 6 and controlling the operation of the heating elements 5.

A vessel for preparing boiling water 4 may be located inside the nutrient vessel 3, representing communicating vessels. The feed vessel 3 is equipped with a pipe 11 for connection to the cold water supply system through a hose 12 and an electromagnetic valve 13. A sensor 14 with contacts 15 and 16 for monitoring the water level in the feed vessel 3 and, respectively, in the vessel for preparing boiling water 4 and control is also installed in the feeding vessel 3 the operation of the heating elements 5. In the housing of the boiler 2 is an automation unit.

The device operates as follows. The switch 17 is turned on. Voltage is applied to the automation unit. The valve opens on the pipeline of the cold water supply system (not shown in the drawing) and the filling vessel 3 and, accordingly, the vessel for filling

preparation of boiling water 4 through the solenoid valve 13, hose 12 and nozzle 11. Upon reaching the specified water level, ensuring the complete immersion of the heating elements, contact 15 of the sensor 14 will close and electric heaters (heating elements) will turn on 5. When the specified water level in the vessels (30-35 mm from the top of the vessel for preparing boiling water 4) the contact 16 of the sensor closes and the electromagnetic valve 13 for supplying cold water from the water supply closes. When boiling, the resulting vapor bubbles, covered with a shell of boiled water, rise upward, lift the lid 18 and into the gap formed between the edge of the vessel 4 and the lid 18, the boiling water is dragged along, which enters the internal cavity of the vessel to collect boiling water 6. The lid 18 serves as a reflector for spray boiling water. The tap for boiling water opens. After filling the vessel for collecting boiling water 5 to a predetermined level, the contact of the sensor 9 will close and the heating elements will be switched off. 4. When the water level drops below the contact of the sensor 10 in the vessel for collecting boiling water 6, 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 decreases. Through the contact of the sensor 15 there is a command to open the electromagnetic valve 13 and cold water enters the vessel for preparing boiling water 4 through the hose 12 and the pipe 11. The cycle is repeated. Since the drain pipe 8 is located in the bottom 7, and the bottom is inclined towards the drain pipe 8, when consuming boiling water, unused boiling water will remain in the vessel 6, which could partially cool the newly prepared portion of boiling water. Therefore, the temperature of boiling water in the collection vessel of the finished boiling water 6 will be higher than that of the prototype.
