Description

The vertical gas furnace of displacement type

Technical field:

The utility model design relates to the vertical gas furnace of a kind of displacement type, belong to domestic gas hot water be used for heating and (or) technical field of function such as bathing.

Background technology:

Vertical gas furnace of displacement type and the wall-hanging gas furnace of once-through type have his own strong points, and are the main utensils that family's gas and hot water is used for heating and bathing.Mostly the at present popular vertical gas furnace of displacement type (as brands such as the Smith of import, heat wave, permanent heat) is the double-level-metal tube-in-tube structure, that is: the inner core bottom is that combustion chamber, middle and upper part are flues, the big water cavities of looping such as inner tank theca face and outer tube inner wall face; Simple in structure, the characteristics of shortage enhanced heat exchange, thereby volume is big, efficient is low; With common other the not too free from worry residence space of present China and relatively the folk custom national conditions of nervous energy situation very do not conform to.

Goal of the invention and content:

The purpose of the utility model design is the build that dwindles vertical gas furnace relatively, makes it account for very small size and space in general family room, improves its heat exchange efficiency simultaneously, outstanding energy-conservation province gas, economical and practical advantage.Summary of the invention is to adopt inner rib cast heat exchanger, its build is dwindled, but have the advantage that the heat exchange stroke is long, heat exchange area is big, heat exchange efficiency is high, can embody the advantage of small body type, big load.

The specific embodiment:

With reference to Figure of description 1 accompanying drawing 2, on top configuration bell (2) bell (2) of body of heater shell (1), smokestack base (3) is arranged; The top of furnace shell (1) is embedded with water temperature and shows that version (5), power switch key (6), water temperature are provided with knob (7), and furnace shell (1) top left and right sides is shaped on number row louvre (8), and furnace shell (1) bottom is shaped on quantity bar shaped fresh air inlet (40); Also dispose temperature controller blind patch (26) and gauge hole cover plate (28) on the furnace shell (1), be shaped on glory hole (9) on the furnace shell (1).

With reference to Fig. 3, in furnace shell (1) bottom, interior configuration burner with stand courage dish (4), flue: promptly be that heat exchanger is commonly called as and be called for short.Burner with stand courage dish (4) is bolt knot burner (29) down, and burner (29) is bolt knot air inlet adjustment valve (30) down, air inlet adjustment valve (30) bolt knot magnetic valve (32), magnetic valve (32) bolt knot combustion gas inlet pipe (33).Placing heat exchanger on the burner with stand courage dish is flue, at flue top configuration flue gas baffle liner (34), flue gas baffle liner (34) is gone up configuration blower fan supporting plate (35), be shaped on mesopore (36) on the blower fan supporting plate, be equipped with flue gas water conservancy diversion box (37) on the blower fan supporting plate (35), flue gas water conservancy diversion box (37) bolt knot blower fan (38), the volute of blower upper end is shaped on exhaust opening (39).

With reference to Fig. 3 Fig. 4 Fig. 5 Fig. 6, placing heat exchanger at burner with stand courage dish (4) is flue.Flue shell (11) and combustion chamber shell (15) looping water cavity (16); The internal face of combustion chamber shell (15) forms combustion chamber (17); Upright between combustion chamber shell (15) and upper perforated plate (18) have several internal-rib fire tubes (12), and being shaped on the internal face of internal-rib fire tube (12) with tube wall is the inner rib plate (13) of one; Constitute the main water cavity (14) of flue by the internal face of flue shell (11) and the outside wall surface of several internal-rib fire tubes (12), the outside wall surface of combustion chamber shell (15), the internal face of upper perforated plate (18) etc., main water cavity (14) is two parts of same water cavity with above-mentioned annular water chamber (16).In the flue bottom, annular water chamber (16) is shaped on glory hole (9) on the position, should be same coaxial aperture with the glory hole (9) on the furnace shell (1).Flue top is shaped on left and right sides delivery port (19), the bottom is shaped on and is shaped on temperature controller seat (25) and sensor holder (27) on left and right sides water inlet (20), the flue shell (11); Be shaped on relief valve connection (21).Be built-in with the heat exchange coil (22) of domestic hot-water supply at main water cavity (14), the intake-outlet joint of heat exchange coil (22) promptly is a sequence number among the figure (23) (24).

The embodiment operation principle:

Combustion gas is flowed into by combustion gas inlet pipe (33), through magnetic valve (32), air inlet adjustment valve (30), is got angry in combustion chamber (17) by burner; Annular water chamber (16) prevents the flame heatsink transverse, flame rises along several internal-rib fire tubes (12) inner chamber, and heat is reinforced and is transformed in the water, and flue gas is through baffle liner (34), blower fan supporting plate mesopore (36), water conservancy diversion box (37), by the blower fan suction, discharge from exhaust opening (39); Meanwhile, heating recirculated water flows into from flue water inlet (20), is reinforced heating in water cavity, flows out from flue delivery port (19), to the interior radiator device.The running water heat exchange coil (22) in the water cavity of flowing through, be the domestic hot-water.Temperature controller is inlaid on the temperature controller seat (25), rotates knob (7), and the water temperature upper limit in the flue can be set; Sensor is inlaid on the sensor holder (27), and the water temperature induced signal is treated to be presented on the water temperature display board (5).The safety valve spinning is on relief valve connection (21), and hydraulic pressure increases in water cavity, overflow decompression thus.

The advantage of vertical gas furnace of the present utility model is that flue heat exchange stroke is long, area is big, and the feature of enhanced heat exchange is outstanding, thus small, efficient is high; Safety is safe, economical and practical, durable durable.
