Abstract
The utility model discloses a gas combustion type domestic water heater, comprising a coal furnace and a hot water exchanger which are connected by pipes. The coal furnace is composed of the boiler base of a bottom, a middle furnace body and an upper furnace cover. The furnace body is a sandwich structure, the upper part thereof is provided with a water inlet opening, and the lower part thereof is provided with a return water opening. The heat exchanger is composed of a shell, heat exchange pieces arranged in the shell and an expansion tank. The heat exchange pieces are connected with the expansion tank. A water inlet opening and a return water opening on the heat exchange pieces are communicated with a water inlet opening and a return water opening on the furnace body. The utility model has the advantages of high thermal efficiency, high safety and more functions.
Description
The utility model relates to a kind of pot-type boiler, particularly a kind of coal pot-type boiler.
Pot-type boiler commonly used at present is generally gas heater or electric heater.The gas heater price is higher, and instructions for use is higher, accident-proneness; The direct-heating type electric heater, though simple in structure, use dangerous; Water-storage electric heater is limited by electricity consumption, and is fragile.More than various water heaters only can be used to provide hot water, function singleness.
The new purpose of this practicality provide a kind of cost lower, safe in utilization, the coal pot-type boiler, this coal pot-type boiler also can be used as common cooking stove.
The technical solution of the utility model is, coal furnace is connected by pipeline with hot water exchanger, coal furnace is made up of the stove seat of bottom, the body of heater at middle part, the bell on top, body of heater is a sandwich, be used to be filled with water, its top is provided with the admission port, and the bottom is provided with water return outlet, burner hearth in the body of heater is a changeable type, comprises coal-fired piece formula or honeycomb briquette fired formula burner hearth; Hot water exchanger comprises housing, housing top is provided with water inlet, the bottom is provided with hot water outlet, the bottom is provided with the hot water changing plate in the housing, admission port on the hot water changing plate, water return outlet are communicated with admission port, water return outlet on the body of heater respectively, the expansion tank of being located at housing top is connected with the hot water changing plate, and expansion tank is provided with water supplement port and water level inspection socket.
For preventing that bell is a sandwich, is provided with asbestos layer in the interlayer from the fire door heat radiation.
The structure of honeycomb briquette fired burner hearth is, upper and lower is annulus, and the centre is a joint pin.
For making hot water circuit better, the admission port on the hot water changing plate, water return outlet can be located at its underpart, and the top of hot water changing plate is connected with expansion tank.
For ease of moisturizing and inspection water level, the level height of the water inlet on the water level inspection socket on the expansion tank, water supplement port, the housing is slightly high successively.
Expansion tank is salable in housing.
The utility model cost is lower, and thermal efficiency height is safe in utilization, can use as common cooking stove at ordinary times, is suitable for applying.
