Description

The utility model relates to domestic mechanical engineering and can be used in gas heating household appliances.

A known heating apparatus (RU 2238483 C2, 7 F24H 1/24, 10/20/2004), comprising a housing with a water jacket that covers the firebox and gas duct, a heat exchanger, which is located in the upper part of the heating apparatus, in the form of a pipe block with rectangular or square pipes sections with turbulators, while the turbulators are freely inserted into the pipes on the rods, and the elements of the turbulators are placed at an angle of 90 ° to the flow of combustion gases [1].

Known heating gas boiler (RU 2269065, F24H 1/00 (2006.01), F23J 15/02 (2006.01), 01/27/2006), made in the form of a rectangular cabinet with thermal protection and a casing, inside which there is a furnace with a burner, a heat exchanger and a pipe the exit of combustion products through the outer wall of the room. In addition, it contains a cartridge with an adsorbing substance, hermetically installed in the outlet of the combustion products between the casing of the rectangular cabinet with thermal protection and the inner surface of the outer wall of the room. In this case, the outlet pipe of the products of combustion behind the outer wall of the room is installed vertically and contains a cone-shaped nozzle with curved planes and guiding and twisting ribs [2].

Known for the prototype apparatus is a gas heating household appliance AOGV-7.4 of the Helios brand, comprising a body with a chimney, a water heating tank, a gas burner, a starting and regulating device [3].

The disadvantage of these heating devices and the boiler is that they cannot be repaired, since all of their working bodies and elements are rigidly fixed in the housing and in case of cracks, burnout of metal, rust holes in the housing, for example pipes or a water jacket, there is no access inside the housing for welding on damaged areas. With such malfunctions, the heating apparatus is usually scrapped and you have to buy a new one, which causes economic damage to consumers.

The design of the heating gas household appliance with the possibility of repairing the water tank is based on the task of extending its service life by giving it maintainability.

This is achieved by the fact that the heating water tank is made in the form of a separate removable tank, equipped with a flange for tight mounting to the housing using fasteners. In this case, the apparatus body is made with a window and support rails on the inner side walls for mounting and dismounting the heating water tank.

The essence of the utility model is illustrated by drawings, which show a household gas heating apparatus with the ability to repair a water tank:

FIG. 1 - household gas heating apparatus with the ability to repair a water tank, side view;

FIG. 2 - view in plan;

FIG. 3 is a view along arrow A in FIG. one;

FIG. 4 is a sectional view of the apparatus according to BB in FIG. 2;

FIG. 5 is a view of a window in the boiler housing along arrow B in FIG. one.

A gas heating household appliance with the possibility of repairing a water tank contains a housing 1 with a chimney 2, a heating water tank 3, a gas burner 4, a starting and regulating device 5. The heating water tank 3 is equipped with vertically mounted pipes 6 for the passage of heated gases to the exhaust pipe 2.

The heating water tank 3 is equipped with nozzles 7 and 8 for water inlet and outlet. A flange 9 is welded to the right side of the heating water tank 3 for tightly fastening it to the housing 1 by means of fasteners 10. For mounting and dismounting the heating water tank 3, the housing 1 is provided with a window 11 and, for example, threaded holes 12 for tightly mounting the heating water flange 9 tank 3. To hold and guide the heating water tank 3 during its installation and dismantling inside the housing 1, support rails 13 and 14 are installed on its side walls. The gas burner 4 is made in the form of a pipe with holes yami to exit the gas. To supply air to the burner 4, holes are provided in the housing 1, not shown in the drawing. A pipe 15 is provided for supplying gas to the burner 4. The starting and control device 5 is equipped with an ignition tube 16 and a spark electrode 17. The housing 1 is mounted on the legs 18.

Gas household heating apparatus with the ability to repair a water tank works as follows. Through the pipe 7 by gravity or using a pump from the heating system, water is supplied to the heating water tank 3, and from the pipe 8 is removed. Using the starting and regulating device 5, gas is supplied to the ignition tube 16. Using the spark electrode 17, the gas in the ignition tube 16 is ignited. After that, gas is supplied through the tube 15 to the gas burner 4. Heated gases pass around the heating water tank 3, as well as through the pipes 6 and heat the water in the tank. The exhaust gases through the pipe 2 are discharged into the atmosphere. Heated water, circulating through the batteries of the heating system, heats the air in the room. The heating of the water is regulated using the starting and regulating device 5. If the heating water tank 3 fails due to cracks, holes from rust, burnout of the metal of the walls or pipes, the fasteners 10 are unscrewed and the heating water tank 3 is removed from the housing 1 through the window 11. Defects in the heating water tank 3 become visible and are eliminated

by welding or welding new sheet overlays. If a defect is found, for example, in pipes 6, then they are cut out by gas cutting in zones “G”, the defects are welded, the pipes are put back into place and welded on the tank. Instead of failed pipes, you can install and weld new pipes.

The proposed gas heating household appliance with the ability to repair a water tank ensures maintainability, increasing the life of the apparatus and obtaining an economic effect.
