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, and a vessel for collecting boiling water with a drain pipe (See the description of utility model No. 42376 "Electric boiler" The variant according to claim 2 of the PM formula , dated 05/30/04., published on 11/27/04. Н 05 В 1/00, 3/78, A 47 J 31/54, 31/56, Fisenko B.L., Fisenko A.B. Fisenko S.B. .)

The technical task of the claimed utility model is to increase the efficiency of the boiler and reduce its size.

The problem is solved by performing a known continuous electric boiler containing a vessel for boiling water with tubular electric heaters (heating elements), a vessel for collecting boiling water and a sensor for monitoring the water level and controlling the operation of heating elements, in which, according to a utility model, the vessel for preparing boiling water is equipped with a pipe for connection to a cold water supply system and a tubular outlet, in which a sensor for monitoring the water level and controlling the operation of the heating elements is installed.

The proposed design of a continuous electric boiler is characterized by a new layout of the main, functional elements of the device, which is associated with the absence of a nutrient vessel. Cold water is no longer supplied to the vessel for boiling water from the nutrient vessel, but directly from the cold water supply system. This significantly reduces the dimensions of the boiler. In addition, it allows you to adjust the ratio of the volumes of water again entering the vessel for boiling water and ready boiling water, which goes into the vessel for collecting boiling water, which makes it possible

to carry out continuous (rather than portioned) water supply and to keep the volume of water in the vessel for preparing boiling water practically at the same level. This increases the reliability and efficiency of the boiler.

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 and widespread use of the inventive boiler.

The essence of the utility model is illustrated by the drawing, which shows a General view of the boiler.

Electric boiler 1 of continuous operation contains a housing 2. In the housing 2 are interconnected vessel for the preparation of boiling water 3 with tubular electric heaters (heating elements) 4 and a vessel for collecting boiling water 5. Heating elements 4 can be fixed on the bottom of the vessel for preparing boiling water 3. A vessel for collecting boiling water 5 can be located both inside the vessel for preparing boiling water 3 and outside on its upper part. The vessel for cooking boiling water 3 is equipped with a pipe 6 for connecting to the cold water supply system through a hose 7 and an electromagnetic valve 8 and a tap 9 with a sensor 10 installed in it with contacts 11 and 12 for monitoring the water level in the vessel for preparing boiling water 3 and controlling the operation of heating elements 4. The vessel for collecting boiling water 5 is equipped with a pipe 13 for connecting boiling water to a tap (not shown in the drawing) and a sensor with contacts 14 and 15 for monitoring the maximum water level in vessel 5 and controlling the operation of the heating elements. In case 2 is located the automation unit.

The device operates as follows. The switch 16 is turned on. Voltage is applied to the automation unit. The valve on the cold water supply system pipe opens (not shown in the drawing) and the vessel for filling boiling water 3 is filled with water through the solenoid valve 8, hose 7 and pipe 6. When the set water level is reached, which ensures complete immersion of the heating elements, the sensor 10 closes (contact 11 ) and the electric heaters (heating elements) will turn on. The sensor 10 controls the level of incoming water from the water supply. Upon reaching the set water level in the tanks (30-35 mm from the top of the tank for boiling water) it will close

sensor 10 (contact 12) and the electromagnetic valve 8 for supplying cold water from the water supply system closes. During boiling, the resulting vapor bubbles coated with a shell of boiled water, rising upward, they lift the lid 17 into the gap between the edge of the vessel 3 and the lid 17 entrain boiling water, which 7 enters the inner cavity of the vessel to collect boiling water. The cover 17 is a reflector for spray boiling water. The tap for boiling water opens. After filling the tank for collecting boiling water 5 to a predetermined level, the sensor 14 closes and the heating elements are switched off. 4. When the water level drops below contact 15 in the vessel for collecting boiling water 5, the heating elements 4 are switched on. At the stage of boiling water and collecting boiling water, the water level in the vessel for preparing boiling water 3 decreases, the sensor 10 (contact 11) opens the solenoid valve 14 and cold water enters the vessel for preparing boiling water 3 through a hose7 and pipe 6. The cycle is repeated.
