Description

The Tubulation type miniature hot-water boiler

The utility model design relate to a kind of Tubulation type miniature hot-water boiler (hereinafter to be referred as: miniature boiler), be to of the improvement of popular civilian small size hot-water boiler at structure and technical elements.

Small size hot-water boiler can be suitable for the general family in cities and towns by being loaded on heating and Water-heating shower system.The existing common weak point of the domestic small size hot-water boiler that is popular at present is: 1, burner in the boiler and heat exchanger are overall structure, if any fault, then the water in boiler and even the system all to be bled off, boiler is disassembled from system, could overhaul, program is numerous and diverse; Though say miniature boiler for 2, the still thick heaviness of body of heater, incompatible with the living space of general family; 3,, be difficult to bear in the economic condition of general family owing to complex structure causes price higher.

The purpose of the utility model design is to overcome the existing above-mentioned deficiency of popular small size hot-water boiler; Under the prerequisite that guarantees the miniature boiler basic function, simplified structure, reduced volume, weight reduction improve utility function.

The improvement measure of miniature boiler of the present utility model is: 1, miniature boiler is to combine the cross sectional shape basically identical of the shell of the two by burner assembly and the two part splits of heat exchange body.Burner assembly be positioned at the heat exchange body under, after the boiler erection, can extract out down from the heat exchange body, be convenient to maintenance.2, adopt the harmonica-type burner of making by stainless sheet steel in the burner assembly, and have devices such as automatic igniting, flame-out safeguard protection, timing, structure light and handy.3, the heat exchange body is to surround a tubular heat exchanger made from thin-wall metal pipe and sheet metal by shell, also has the light and handy characteristics of structure.

Specification drawings attached 9 width of cloth of the miniature boiler of the utility model design, represented parts and the position of sequence number is respectively among the figure: 1, burner assembly, 2, ignition switch, 3, indicator lamp, 4, timer knob, 5, the flame adjusting knob, 6, burner, 7, the discharge needle bar, 8, breather valve, 9, magnetic valve, 10, the tracheae plug, 11, battery case, 12, ignition, 13, burner assembly shell, 14, footing, 15, fish cheek formula wind hole; 16, heat exchange body, 17, the heat exchange body housing, 18, the combustion chamber, 19, the combustion chamber inner casing, 20, combustor outer casing, 21, glory hole, 22, flame observes conduit, 23, lower perforated plate, 24, upper perforated plate, 25, tube bank, 26, heat exchanger water cavity shell, 27, water cavity, 28, water inlet pipe, 29, outlet pipe, 30, snap ring, 31, smoke guiding cover, 32, enclosure, 33, fish cheek formula wind hole, 34, anti-down aerofoil, 35, go up the hole circle, 36, cover on the heat exchange body housing.

Now in conjunction with Figure of description, the architectural feature of miniature boiler of the present utility model is described further.

Fig. 1 is the front view of miniature boiler, and Fig. 2 is that the C of Fig. 1 is the side view of miniature boiler to view, illustrates that miniature boiler is to be combined by burner assembly 1 and 16 splits of heat exchange body, burner become 1 be positioned at heat exchange body 16 under; After the boiler erection, burner assembly can be extracted out down from the heat exchange body, thus convenient maintenance to burner.

Fig. 3 is the B-B cutaway view (double as specification digest accompanying drawing) of Fig. 2, Fig. 4 is the A-A cutaway view of Fig. 1, the design feature of heat exchange body 16 that miniature boiler is described is as follows: surround a tubular heat exchanger by body housing 17, the bottom of this tubular heat exchanger is shaped on combustion chamber 18, and combustion chamber 18 is made of inner casing 19 and shell 20; The top of inner casing 18 promptly is a lower perforated plate 23, plays fixing tube bank 25 two-port with upper perforated plate 24; So just formed by the internal face of the outside wall surface of combustion chamber inner casing 19, shell 20 and restrained the same water cavity 27 that the forward surface etc. of internal face, lower perforated plate 23 and the upper perforated plate 24 of 25 outside wall surface, water cavity shell 26 is constituted.Also be shaped on glory hole 21 on the intermediate water jacket wall of combustion chamber 18, glory hole 21 outer being equipped with are observed conduit 22.On the outer wall of combustor outer casing 19, be shaped on water inlet pipe 28, top at heat exchanger water cavity shell 26 is shaped on outlet pipe 29, the port that connects water inlet pipe 28 and outlet pipe 29 with snap ring 80, and snap ring 30 is fastened on the inwall that fixes on body housing 17, thereby has realized the connection of tubular heat exchanger and body housing 17.Fig. 5 is the D-D profile of Fig. 1, and Fig. 6 is the E-E profile of Fig. 1, the said structure of aid illustration miniature boiler heat exchange body 16.

Fig. 7 also is the A-A cutaway view of Fig. 1, with Fig. 4 difference is: combustor outer casing 20 is linked to be with same cylinder directly with water cavity shell 26, to enlarge the volume of heat exchanger water cavity, increases water capacity, the suitable water boiler of doing.Miniature boiler as water boiler also should be shaped on water level meter and temperature controller etc.

Fig. 8 be the F of Fig. 1 to view, in conjunction with Fig. 3 Fig. 4, the harmonica-type burner 6 that burner assembly 1 adopts stainless sheet steel to make is described, this has brought into play important function for weight that alleviates burner assembly and reduced volume.Both sides at burning assembly shell 13 also are shaped on fish cheek formula fresh air inlet 15.

By Fig. 1 to Fig. 4, also shown the structure of enclosure 32, in the shell of enclosure 32, be shaped on anti-down aerofoil 34, on the two side wall panels of smoke evacuation, be shaped on fish cheek formula wind hole 33, the top of enclosure 32 is shaped on hole circle 35, but the general chimney of socket.

In the shaft space of tube bank 25 is in the pore, can place spoiler, and to strengthen flame and the exothermic coefficient of restraining inwall, spoiler (not showing in the Figure of description) can be made helical form or irregular with sheet metal.Be to enlarge the effective heat exchange area of hot flame cigarette and tube bank, can make and be shaped on some and tube wall on the inwall of tube bank 25 is the longitudinal fin of one, and Fig. 9 is as the another width of cloth D-D profile of Fig. 1, and explanation is the tube bank 25 that employing is shaped on some inner rib plates.

The operation principle of miniature boiler of the present utility model is: press ignition switch 2, flame fires in combustion chamber 18, the water in the heating interlayer water jacket; The hot flame cigarette rises along the inwall of several tube banks 25, adds the water in the hot-water cavity 27.Meanwhile, water flows into water cavity from water inlet pipe 28, after being heated, flows out from outlet pipe 29, flows to required parts such as radiator or shower cabinet.

Because miniature boiler of the present utility model has that structure is light and handy, build is modest, hot water speed is fast, the thermal efficiency is high, manufacturing cost is lower and advantage such as energy savings, and has good utility function, is applicable to general family.
