Abstract

The utility model relates to a novel household energy saving heating boiler. The novel household energy saving heating boiler is characterized in that a movable water jacket boiler cover is arranged on a boiler body; a smoke channel is designed into a square, and a plurality of water pipes are arranged in the interior; the water pipes are mutually parallel, are arranged line to line, and are respectively connected with the water jacket of the smoke channel; the top hole of the smoke channel is provided with a movable upper cover. As water heating area is added on the household energy saving heating boiler and a structure which is convenient to remove dust is adopted, smoke heat obtains full use, and heat efficiency is raised to 72 to 80% from original 35 to 40%. The household energy saving heating boiler is suitable for heating with radiators for companies and households; meanwhile, the utility model can also boil water, cook dishes, make meals, etc.

Description

Household energy saving heating boiler

The utility model relates to a kind of civilian heating boiler, belongs to heating service equipment.

The flue of existing civilian heating boiler is cylindrical, is provided with the some water pipes that communicate with the flue water jacket in the flue.When flame and flue gas enter flue from boiler body, when being discharged by floss hole then, body of heater stays a part of heat, and water jacket, water pipe in the flue stay the remaining heat of part again, pass in the heating system by recirculated water, realize the heat supply purpose.Owing to cylindrical flue all is an acute angle with crossing two angles that form of every inner water pipe, so the water pipe setting is many more, its angle is many more, the easiest deposition dust in the angle, difficult again dedusting, directly influence heating, smoke discharging effect.So existing cylindrical boiler flue, inner water pipe arrangement mode is simple, and quantity is few, and flue gas is with the straight-line pass flue basically, smoke evacuation afterbody temperature height, thermal loss is big.In addition, the body of heater of most of boilers is vertical setting with flue, the boiler function singleness of this structure.Also have body of heater and flue off plumb, it has increased the direct-fired function of heater, the user, but when not needing to the heater heat supply, the flame in the combustion chamber concentrates on the bell, and most radiant heat has been wasted.

The purpose of this utility model is: change the shape of existing flue, the heating surface area of increase water pipe in flue and on the body of heater, thereby the thermal efficiency of raising boiler.

The technical solution of the utility model is: a kind of domestic energy-saving heating boiler, form by water jacket furnace and water jacket flue, on this water jacket furnace feeding port is arranged, air outlet and returning pipe joint, there is fire grate the centre, on the water jacket flue titting water outlet is arranged, it is characterized in that: its cross section of said flue is square, and there are the some water pipes that communicate with water jacket in the walling of flue respectively inside, and this water pipe is parallel to each other, alternately, flue top mouth has movable loam cake.

Can be connected in the side between the flue of present technique and the body of heater, be provided with movably water jacket bell at the body of heater top, have on this bell two with heating system water pipe connecting joint.

Because movable water jacket bell is in the top that flame is concentrated, and removes bell, can cook, it is civilian very convenient to heat up water etc.When not required with water jacket bell return, continue as the heating system heating, this is than the original boiler thermal output that improved during with iron covering.Adopt square flue, flue sidewall is the plane, it and water pipe join, at first, on manufacturing process, be the simple of concave surface than sidewall, second, what contact-making surface formed all is the right angle, compare with original acute angle and to help dedusting, so the water pipe of square flue internal arrangement just can be than original arrangement mode freedom during with circular flue, quantity is many.Present technique in square flue with some water pipes alternately, both increased water pipe, made heating surface many, make the flue gas curve negotiating again, increased stroke distances and strengthened flue gas washing away heating surface, in a word when not influencing normal ventilation smoke exhaust, utilize the heat of flue gas fully, reduce heat loss due to exhaust gas to greatest extent.Being also advantageous in that of present technique: a mobilizable loam cake is arranged at the flue top, though it is the connector between square flue and the round kiln tube, the more important thing is open this loam cake can be with hairbrush to the flue dedusting, the each side that boiler is heated has good thermal conductivity.Adopt the design's civil boiler, its thermal efficiency brings up to 72～80% by original 35～40%.

Below in conjunction with a description of drawings embodiment of the present utility model.

Fig. 1 is the structural representation of the utility model domestic energy-saving heating boiler.

Fig. 2 is the vertical view of Fig. 1.

Among the figure, body of heater (5) has water jacket samdwich, and air outlet (1) is arranged on the sidewall of body of heater (5), feeding port (4), return pipe (3) joint, there is fire grate (2) at the middle part, and technical characterictic of the present utility model is, body of heater (5) is connected with flue (9) side, the movable bell (7) of a band water jacket is arranged on the body of heater (5), remove this bell (7) and can do civilian heating up water, cook etc., bell (7) return can be the heating system heat supply.Water swivel (6) on the bell of present embodiment (7) is connected with heat-resistant rubber hose with the steam heating pipe coupling part.Body of heater (5) and flue (9) are connected by one section passage of flame (8) between the side, and this passage also is a water jacket, is deltiod.The water jacket flue (9) of present technique is designed to square, inside is equipped with the some water pipes (10) that communicate with the water jacket of walling of flue respectively, this water pipe is parallel to each other, alternately, square flue (9) top connects circular stove tube by movable loam cake (12), and pulling down loam cake (12) can be to the dedusting of flue inside.The square flue surface is provided with titting water outlet (11).

Claims

1, a kind of domestic energy-saving heating boiler, form by water jacket furnace and water jacket flue, on this water jacket furnace feeding port is arranged, air outlet, returning pipe joint, fire grate is arranged in the water jacket furnace, on the water jacket flue titting water outlet is arranged, it is characterized in that: its cross section of said flue is square, there are the some water pipes that communicate with water jacket in the walling of flue respectively inside, this water pipe is parallel to each other, and alternately, flue top mouth has movable loam cake.

2, according to the said a kind of domestic energy-saving heating boiler of claim 1, it is characterized in that: be connected in the side between flue and the body of heater, the body of heater top is provided with movable water jacket bell, have on this bell two with heating system water pipe connecting joint.
